In addition, the mounting base plate 310 is fixedly arranged on the guide seat 200, the plane where the mounting base plate 310 is located is parallel to the plane where the conveying table 120 is located, so that the flatness of the material belt 20 clamped by the driving roller 320 and the conveying table 120 is ensured under the driving of the motor, the bending of the material belt 20 is avoided, the contact area between the material belt 20 and the driving roller 320 is reduced compared with the existing technology of the clamp conveying mode, the clamping force of the driving roller 320 on the material belt 20 is reduced, and thus the indentation on the surface of the material belt 20 is reduced. In addition, the driven roller 330 is located between the placement table 110 and the conveying table 120, and the driven roller 330 abuts against the material belt 20 to cooperate with the driving roller 320 to advance with the material belt 20, so as to ensure the flatness of the material belt 20 in the conveying process and avoid the bending of the material belt 20, thereby improving the stability of the conveying of the material belt 20 and the production quality of the product.

[0033] In one of the embodiments, the conveying table 120 and the guide seat 200 are integrally formed, so as to improve the connection strength of the conveying table 120 and the guide seat 200 and ensure a stable conveying channel of the material belt 20 through the guide through slot 201.

[0034] As shown in FIGS. 1, 2 and 3, in one of the embodiments, the first end of the mounting base plate 310 is provided with a first mounting portion 311, the second end of the mounting base plate 310 is provided with a second mounting portion 312, the driving roller 320 is rotatably arranged on the first mounting portion 311, the driven roller 330 is rotatably arranged on the second mounting portion 312, and the first mounting portion 311 and the second mounting portion 312 are located on the same side of the mounting base plate 310.

[0035] ​In one of the embodiments, the height of the placing table 110 is equal to the height of the conveying table 120, so that the height of the material belt 20 on the placing table 110 is consistent with the height of the conveying table 120, avoiding the height difference between the placing table 110 and the conveying table 120, thereby avoiding the bending of the material belt 20 due to the inclined placement during the conveying process of the material belt 20.

[0036] As shown in Figure 1 and Figure 2 In one of the embodiments, the base 100 further comprises a connecting guide shaft 130, the placing table 110 and the conveying table 120 are oppositely arranged, and the two ends of the connecting guide shaft 130 are connected to the placing table 110 and the conveying table 120 respectively. In this embodiment, since the two ends of the connecting guide shaft 130 are connected to the placing table 110 and the conveying table 120 respectively, the positions of the placing table 110 and the conveying table 120 are relatively fixed, avoiding the separation of the placing table 110 and the conveying table 120 during the conveying process of the material belt 20, thereby affecting the conveying of the material belt 20.

The operator can appropriately adjust the distance between the placing table 110 and the conveying table 120 according to the length or weight of the material belt 20, preventing the material belt 20 from being too heavy or too long, so that the material belt 20 bends and falls into the space region between the placing table 110 and the conveying table 120, thereby affecting the conveying of the material belt 20.

[0038] In one of the embodiments, the anti-indentation and anti-bending feeding mechanism 10 further comprises a buffer rubber layer (not shown in the figure), which is arranged on the placing table 110. Specifically, the buffer rubber layer is arranged on the upper surface of the placing table 110, i.e. the side of the placing table 110 that contacts the material belt 20. The buffer rubber layer is used to prevent the material belt 20 from being abraded by the placing table 110. In this embodiment, the buffer rubber layer is arranged on the placing table 110, effectively preventing the surface of the material belt 20 from directly contacting the upper surface of the placing table 110 during the conveying process, thereby reducing the occurrence of scratches on the surface of the material belt 20.

[0039] In one of the embodiments, the inner wall of the guide channel 201 is coated with heat-conducting silicone grease (not shown in the figure), which is used to quickly dissipate heat from the guide channel 201. In this embodiment, since the driving roller 320 and the driven roller 330 respectively contact and rub against the material belt 20, some heat is generated. In order to prevent the material belt 20 from softening and bending due to heat, the inner wall of the guide channel 201 is coated with heat-conducting silicone grease, ensuring that the heat in the guide channel 201 is quickly dissipated.

[0040] Further, as Figure 1 and Figure 2 shown, in one embodiment, the mounting substrate 310 is formed with a plurality of heat dissipation through holes 310a, which are arranged at intervals adjacent to the guide through groove 201 to ensure that the heat in the guide through groove 201 is quickly dissipated from the plurality of heat dissipation through holes 310a.

[0041] The present disclosure also provides a stamping die comprising the anti-indentation and anti-bending feeding mechanism 10 of any of the above embodiments.

[0042] Compared with the prior art, the present disclosure has at least the following advantages:

[0043] The anti-indentation and anti-bending feeding mechanism 10 of the present disclosure, since the guide seat 200 is arranged on the transmission table 120, the guide seat 200 is provided with a guide through groove 201, and the placement table 110 and the transmission table 120 are arranged at intervals, so that the material belt 20 can be guided from the placement table 110 to the transmission table 120 through the guide through groove 201, preventing the material belt 20 from being bent due to position deviation during the conveying process, so as to continuously stamp the material belt 20 subsequently. In addition, since the mounting substrate 310 is fixedly arranged on the guide seat 200, the plane on which the mounting substrate 310 is arranged is parallel to the plane on which the transmission table 120 is arranged, ensuring that the driven roller 320 and the transmission table 120 clamp the material belt 20 flat under the drive of the motor, avoiding the bending of the material belt 20. Compared with the existing clamp conveying method, the contact area between the material belt 20 and the driven roller 320 is reduced, the clamping force of the driven roller 320 on the material belt 20 is reduced, and the indentation on the surface of the material belt 20 is reduced. Since the driven roller 330 is located between the placement table 110 and the transmission table 120, and the driven roller 330 abuts against the material belt 20 to cooperate with the driven roller 320 to advance with the material belt 20, the flatness of the material belt 20 during the conveying process is ensured, and the bending of the material belt 20 is avoided, thereby improving the stability of the conveying of the material belt 20, and further improving the production quality of the product.

[0044] The above-described embodiments only express several embodiments of the present disclosure, which are described in detail and specifically, but should not be understood as limiting the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are within the protection scope of the present disclosure.
