Description

Technical Field

[0001] This utility model relates to the technical field of belt conveying, specifically to a belt drive structure. Background Technology

[0002] After the continuous strip material is stamped into the corresponding shaped product by the stamping die, the strip material needs to be collected by the scrap collection wheel at the rear. When the strip material is metal, due to the smooth surface of the strip material, slippage may occur during the actual scrap collection process. This will cause asynchrony between the conveying of the strip material at the front and the winding of the scrap collection wheel at the rear. In addition, the inertia of the scrap collection wheel will also pull the strip material when it is not needed, which will cause the strip material located below the stamping die to be misaligned, making it impossible to obtain the stamped product accurately and reliably. Therefore, it is urgent to develop a strip material transmission mechanism to ensure that the strip material located at the stamping die position is always in a taut state, and to ensure the reliable and stable operation of the stamping die. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a material belt drive structure that ensures the material belt located at the stamping die position is always under tension, thereby ensuring reliable and stable operation of the die stamping process.

[0004] A belt drive structure, characterized in that it comprises: Mold assembly, which includes upper mold, lower mold, lower mold platform, and mold placement rack; Material strip; First set of material pulling rollers; First buffer wheel; Second set of material pulling rollers; Second buffer wheel; Scrap wheels; And product conveying equipment, including an upper conveyor belt and a vertical frame; The strip material is conveyed backward through the punching area between the upper and lower dies. A lower die platform is provided on the outer periphery of the lower die. A first pull roller group is fixed behind the lower die platform corresponding to the direction of the strip's travel. The strip material passes through the passage gap between the first pull roller groups. A first buffer wheel is provided below the mounting plate of the mold placement frame. The strip material is conveyed towards the first buffer wheel after being turned by the first pull roller group. The upper die punches the corresponding area of ​​the strip to obtain a product. The product is separated from the scrap belt and transferred to the upper conveyor belt by a transfer robot. The product conveying device is located behind the mold assembly. The vertical frame... A second pulling roller group and a second buffer wheel should be arranged sequentially from top to bottom between the front uprights on both sides of the first buffer wheel. After the material belt changes direction along the first buffer wheel, it passes through the gap of the second pulling roller group and turns, and then passes through the second buffer wheel towards the waste collection wheel. The second buffer wheel is sleeved in the central area of ​​the crossbar along its length. The two ends of the crossbar along its length are respectively embedded in the vertical guide slots of the corresponding front uprights. A buffer spring is also provided in the vertical guide slot. The top of the buffer spring is fixedly sleeved to the corresponding end of the crossbar. The buffer spring is used to adjust the height position of the second buffer wheel, thereby ensuring the tension of the material belt.

[0005] Its further features are: The waste collection wheel is located in the lower cavity of the vertical frame, which makes the entire structure occupy a relatively small area and reduces land costs. Both the first and second pull roller groups include a drive wheel and a driven wheel. The travel speed and travel time of the two sets of drive wheels are synchronized. The drive wheel and the driven wheel press tightly against the surface of the material strip. When the drive wheel has no power, the material strip is locked and cannot travel. This ensures that after each mold opening, the first and second pull roller groups synchronously pull the material strip of the same length. A reversing wheel is also provided between the second pulling roller group and the second buffer wheel. The material belt output by the second pulling roller group is reversed again by the reversing wheel and flows to the input area of ​​the second buffer wheel. The second buffer wheel turns the material belt again and flows to the waste collection wheel behind. The winding of the waste collection wheel and the material belt conveyor wheel move or stop synchronously. When the waste collection wheel stops, it will generate inertial rotation. Since the material belt is locked by the first pulling roller group and the second pulling roller group, the material belt will not be misaligned, ensuring the stable and reliable operation of the material belt. The first pull roller group is located on the side of the lower mold table near the vertical frame. A first buffer wheel is located directly below the first pull roller group to ensure that the material strip is turned into a vertical conveying strip as it passes through the first pull roller group. The clearance of the second pull roller group is higher than the upper surface of the first buffer wheel, which ensures that the material strip is conveyed obliquely upward through the clearance of the second pull roller group.

[0006] With this invention, two sets of pull rollers are set after the strip leaves the mold to ensure that the inertia of the waste collection wheel will not affect the front strip. When the strip slips relative to the waste collection wheel, the buffer spring is used to adjust the height of the second buffer wheel, thereby ensuring the tension of the strip. This ensures that the strip located at the stamping mold position is always in a taut state, ensuring reliable and stable operation of the mold stamping operation. Attached Figure Description

Detailed Implementation

[0008] A belt drive structure, see Figure 1 It includes a mold assembly 10, a material strip 20, a first pulling roller group 30, a first buffer wheel 40, a second pulling roller group 50, a second buffer wheel 60, a waste collection wheel 70, and a product conveying device 80. Mold assembly 10 includes upper mold 11, lower mold 12, lower mold platform 13, and mold placement rack 14; The product conveying equipment 80 includes an upper conveyor belt 81 and a vertical frame 82; The strip 20 is conveyed backward through the punching area between the upper die 11 and the lower die 12. A lower die platform 13 is provided on the outer periphery of the lower die 12. A first pull roller group 30 is fixed behind the lower die platform 13 corresponding to the traveling direction of the strip 20. The strip 20 passes through the passage gap between the first pull roller groups 30. A first buffer wheel 40 is provided below the mounting plate of the mold placement frame 14. The strip 20 is conveyed towards the first buffer wheel 40 after being turned by the first pull roller group 30. The upper die 11 punches the corresponding area of ​​the strip to obtain the product. The product is separated from the waste strip and transferred to the upper conveyor belt 81 by a transfer robot (not shown in the figure, which is a mature existing technology). The product transfer device 80 is located behind the mold assembly 10. Vertical frame 82 A second material pulling roller group 50 and a second buffer roller 60 are arranged sequentially from top to bottom between the two front uprights 83 corresponding to the first buffer roller 40. After the material belt 20 changes direction along the first buffer roller 40, it passes through the gap of the second material pulling roller group 50 and turns. Then it passes through the second buffer roller 60 and faces the waste collection wheel 70. The second buffer roller 60 is sleeved in the central area of ​​the crossbar 61 along its length. The two ends of the crossbar 61 along its length are respectively embedded in the vertical guide slots 84 of the corresponding front uprights 83. A buffer spring 62 is also provided in the vertical guide slots 84. The top of the buffer spring 62 is fixedly sleeved to the corresponding end of the crossbar 61. The buffer spring 62 is used to adjust the height position of the second buffer roller 60, thereby ensuring the tension of the material belt.

[0009] In a specific embodiment, the waste collection wheel 70 is set in the lower cavity of the vertical frame 82, which makes the entire structure occupy a relatively small area and reduces land costs. Both the first pulling roller group 30 and the second pulling roller group 50 include a driving wheel 1 and a driven wheel 2. The traveling speed and traveling time of the two driving wheels 1 are synchronized. The driving wheel 1 and the driven wheel 2 press tightly against the surface of the material strip 20. When the driving wheel 1 has no power, the material strip 20 is locked and cannot travel. This ensures that after each mold opening, the first pulling roller group 30 and the second pulling roller group 50 synchronously pull the material strip of the same length. A reversing wheel 90 is also provided between the second pulling roller group 50 and the second buffer wheel 60. The material belt output from the second pulling roller group 50 is reversed again by the reversing wheel 90 and flows to the input area of ​​the second buffer wheel 60. The second buffer wheel 60 turns the material belt 20 again and flows to the waste collection wheel 70 behind. The winding of the waste collection wheel 70 and the material belt conveyor wheel move or stop synchronously. When the waste collection wheel 70 stops, it will generate inertial rotation. Since the material belt is locked by the first pulling roller group 30 and the second pulling roller group 50 at the same time, the material belt 20 will not be misaligned, ensuring the stable and reliable operation of the material belt 20. The first pull roller group 30 is located on the side of the lower mold table 13 near the vertical frame 82. A first buffer wheel 40 is located directly below the first pull roller group 30 to ensure that the material strip is turned into a vertical conveying strip as it passes through the first pull roller group 30. The passage gap of the second pull roller group 50 is higher than the upper surface of the first buffer wheel 40, which ensures that the material belt is conveyed obliquely upward through the passage gap of the second pull roller group 50.

[0010] Its working principle is as follows: After the material strip leaves the mold, two sets of pull rollers are set to ensure that the inertia of the waste collection wheel will not affect the front material strip. When the material strip slips relative to the waste collection wheel, the buffer spring is used to adjust the height position of the second buffer wheel, thereby ensuring the tension arrangement of the material strip. This ensures that the material strip located at the stamping die position is always in a taut state, ensuring reliable and stable operation of the die stamping operation.
