Detailed Implementation

[0024] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0025] This application provides a sheet conveying device for receiving and conveying sheets conveyed in the previous process. This device acts as an intermediary between two processes, saving time and effort and improving production efficiency.

[0026] like Figure 1-3 As shown, the conveying device 100 includes: a frame 10 supported on the ground, a drive roller 20 rotatably mounted at the front end of the frame 10, a tension roller 30 rotatably mounted at the rear end of the frame 10, a drive mechanism 40 that is connected to the drive roller 20, and a conveyor belt 50 that is wound around the drive roller 20 and the tension roller 30 at the same time.

[0027] The frame 10 includes a support base 1 and a pair of support beams 2 mounted on top of the support base 1. The pair of support beams 2 are arranged opposite each other from left to right, and each support beam 2 extends in the front-to-back direction. The support base 1 provides stable support at the bottom of the pair of support beams 2. A drive roller 20 and a tension roller 30 are supported opposite each other from front to back between the pair of support beams 2, and both extend in the left-to-right direction. The drive roller 20 is mounted between the front ends of the pair of support beams 2, and the tension roller 30 is mounted between the rear ends of the pair of support beams 2.

[0028] The bottom of the support frame 1 is also equipped with several adjustable feet 9. The overall height of the frame 10 can be adjusted by adjusting the feet 9 to adapt to the height of different production lines and avoid height differences with other workstations that may affect the conveying of sheet materials.

[0029] The conveyor belt 50 is taut between the drive roller 20 and the tension roller 30. When the drive roller 20 rotates, it drives the tension roller 30 to rotate synchronously. It also moves in the front-back direction along with the rotation of the drive roller 20 and the tension roller 30 to realize the conveying of the sheet material.

[0030] The drive mechanism 40 is used to drive the drive roller 20 to rotate relative to the frame 10 around its own axis, thereby driving the conveyor belt 50 that is tensioned on the drive roller 20.

[0031] like Figure 1 , 3 As shown, the drive mechanism 40 includes a drive motor 3, a first gear 4, a second gear 5, and a transmission chain 6. The drive motor 3 is fixedly mounted on the support base 1. The first gear 4 and the second gear 5 are arranged on the same side of the frame 10. The first gear 4 is coaxially arranged with the transmission shaft of the drive motor 3, and the second gear 5 is coaxially arranged with the drive roller 20. The transmission chain 6 meshes with the first gear 4 and the second gear 5 simultaneously. The drive mechanism 40 drives the drive roller 20 to rotate through the meshing between the gears and the chain.

[0032] To ensure the safety of the operating environment, the drive mechanism 40 also includes a protective cover 7, which covers the outside of the second gear 5 and at least part of the transmission chain 6, thereby preventing the sheet material on the conveyor belt 50 and the operator from coming into contact with the second gear 5 and the transmission chain 6, and ensuring the safe transport of the sheet material.

[0033] like Figure 1-3As shown, each of the rear ends of a pair of support beams 2 is equipped with a tensioning assembly 8 that is pulsatorically connected to the tensioning roller 30. Each tensioning assembly 8 includes a mounting base 81 fixed to the inner side of the support beam 2, a sliding bearing seat (not shown) that slidably engages with the mounting base 81, and an adjusting screw 82 that is pulsatorically connected to the sliding bearing seat. The two ends of the tensioning roller 30 engage with the sliding bearing seats of the tensioning assembly 8, and are mounted on the frame 10 so as to be able to rotate around its own axis and move in the front-back direction. The sliding bearing seat is configured to move relative to the frame 10 in the front-back direction on the mounting base 81 when the adjusting screw 82 is rotated. The operator controls the position of the sliding bearing seat in the front-back direction by rotating the adjusting screw 82. After prolonged use, the conveyor belt 50 will gradually stretch and become loose between the drive roller 20 and the tension roller 30. During rotation, the conveyor belt 50 will slip on the drive roller 20 and the tension roller 30, causing conveying delays and severely affecting conveying efficiency. The tensioning assembly 8 adjusts the position of the tension roller 30 in the front-back direction, ensuring that the conveyor belt 50 is taut between the drive roller 20 and the tension roller 30, maintaining a tight fit with them, thus preventing slippage during rotation. This tensioning assembly 8 has a simple structure, is easy to adjust, reduces production costs, and is suitable for various production lines.

[0034] like Figure 1 , 4 As shown in Figure 5, the surface of the drive roller 20 has at least one first limiting annular groove 201; the surface of the tension roller 30 has at least one second limiting annular groove 301; the side of the conveyor belt 50 that contacts the drive roller 20 and the tension roller 30 has at least one limiting rib (not shown in the figure), which extends in the front-back direction and simultaneously cooperates with at least one first limiting annular groove 201 and at least one second limiting annular groove 301. The first limiting annular groove 201 and the second limiting annular groove 301 are both annular grooves with a width of 8-12 mm and a depth of 5-10 mm, for the limiting rib to be embedded in, so as to prevent the conveyor belt 50 from deviating from the conveying direction on the drive roller 20 and the tension roller 30, which would cause the sheet to run off-center, and further ensure the stability of the sheet conveying.

[0035] like Figure 1 , 3 As shown, between the drive roller 20 and the tension roller 30, there are several transition steel rollers 60 arranged at intervals from front to back. These transition steel rollers 60 are all parallel to the drive roller 20. Each transition steel roller 60 is rotatably mounted between a pair of support beams 2, increasing the stability of the pair of support beams 2 and providing support force below the conveyor belt 50. If there were no transition steel rollers 60 supporting the conveyor belt 50, it would sag under the weight of the sheet when carrying it, and would gradually stretch after long-term transportation, affecting the service life of the conveyor belt 50.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application. The scope of protection claimed by this application is defined by the appended claims, specification, and their equivalents.
