The terminology used in the description herein is for the purpose of description The term "and/or" used herein includes any combination of one or more of the associated listed items.

参照图1，示出了本发明一个实施例的立体示意图。如图所示，本实施例包括基板101、调节板102、传送带201、主动带轮202、从动带轮203与电机204。主动带轮202与电机204的驱动轴固接，传送带201分别绕设在主动带轮202与从动带轮203之上，随着电机204的转动，传送带201可以发生正反转动。Referring to Figure 1, a perspective schematic view of one embodiment of the present invention is shown. As shown, the present embodiment includes a substrate 101, an adjustment plate 102, a conveyor belt 201, a drive pulley 202, a driven pulley 203, and a motor 204. The driving pulley 202 is fixed to the driving shaft of the motor 204, and the conveyor belt 201 is respectively wound around the driving pulley 202 and the driven pulley 203. As the motor 204 rotates, the conveyor belt 201 can rotate forward and backward.

电机204固接在调节板102的一侧，其驱动轴穿过基板101与调节板102上的开口后与位于基板101一侧的主动带轮202固接。从动带轮203相对基板101固定，具体的，传动机构还包括转轴103、转轴板104与支撑螺钉301，转轴板104通过支撑螺钉301与基板101固定连接，并相对基板101平行，转轴103的两端分别与基板101、转轴板104转动连接，从动带轮203固定在转轴103上，可与转轴103一体转动。The motor 204 is fixed to one side of the adjustment plate 102, and the drive shaft passes through the opening of the substrate 101 and the adjustment plate 102, and is fixed to the driving pulley 202 on the side of the substrate 101. The driven pulley 203 is fixed to the substrate 101. Specifically, the transmission mechanism further includes a rotating shaft 103, a rotating shaft plate 104 and a supporting screw 301. The rotating shaft plate 104 is fixedly connected to the substrate 101 through the supporting screw 301, and is parallel to the substrate 101, and the rotating shaft 103 is The two ends are respectively rotatably connected to the substrate 101 and the rotating shaft 104, and the driven pulley 203 is fixed to the rotating shaft 103, and is rotatable integrally with the rotating shaft 103.

As the pulley axial spacing changes, the tension of the conveyor belt 201 also changes. In this way, the tension adjustment of the conveyor belt 201 can be performed. Since there is no resistance to the belt 201 by the tensioning wheel, the sides of the belt 201 are not deformed, so that the belt 201 can be accurately driven with the loose side and the tight side alternately changed.

The substrate 101 is provided with a strip hole 1011 along the moving direction of the adjustment plate 102. The fastening screw 302 passes through the strip hole 1011 and then rotates. The adjusting plate 102 can be slid along the strip hole with respect to the substrate 101 after the fastening screw 302 is unscrewed, and can be locked on the substrate 101 by the fastening screw 302.

紧固螺钉302优选为四处，分别设置在基板101的四角，保证调节板102与基板101之间牢固连接。The fastening screws 302 are preferably four places, which are respectively disposed at the four corners of the substrate 101 to ensure a firm connection between the adjustment plate 102 and the substrate 101.

此外，为实现调节板102相对基板101的运动，本发明还包括调节螺钉303，基板101的一侧设有凸台1012，凸台1012上设有螺纹孔，调节螺钉303沿调节板102的运动方向旋在螺纹孔内，其端部与调节板102相互抵持，随着调节螺钉303的旋动便可以推动调节板102相对基板101运动。In addition, in order to realize the movement of the adjusting plate 102 relative to the substrate 101, the present invention further includes an adjusting screw 303. One side of the substrate 101 is provided with a boss 1012, and the boss 1012 is provided with a threaded hole, and the movement of the adjusting screw 303 along the adjusting plate 102 is provided. The direction is screwed into the threaded hole, and the end portion thereof abuts against the adjusting plate 102, and the adjustment plate 102 can be pushed to move relative to the substrate 101 as the adjusting screw 303 is rotated.

除上述实施例外，本发明还公开了其他的实施例，比如可以是从动带轮相对主动带轮运动，具体是将主动带轮以及电机固定在基板上，而将从动带轮固定在调节板上，调节板与基板之间仍采用紧固螺钉、调节螺钉连接，同样可以实现传送带的张紧。In addition to the above embodiments, the present invention also discloses other embodiments, such as the driven pulley relative to the driving pulley, specifically the driving pulley and the motor are fixed on the substrate, and the driven pulley is fixed in the adjustment. On the plate, the adjusting plate and the substrate are still connected by fastening screws and adjusting screws, and the tension of the conveyor belt can also be achieved.

又比如主动带轮与从动带轮均可以运动，主动带轮与电机固定在一块调节板上，从动带轮固定在另一块调节板上，两块调节板可独立的相对基板运动，此实施例适用于单侧行程受限的情况。For example, both the primary pulley and the driven pulley can be moved, the primary pulley and the motor are fixed on one adjustment plate, and the driven pulley is fixed on another adjustment plate, and the two adjustment plates can independently move relative to the substrate.
