Description

Technical Field

[0001] This utility model belongs to the technical field of rubber strip cutting equipment, and relates to a feeding device for a rubber strip cutting machine. Background Technology

[0002] Rubber strip cutting equipment is a common mechanical device that helps people quickly cut rubber into uniform shapes. A feeding device is needed to transfer and load the cut rubber strips.

[0003] Patent application number CN202223158056.9 discloses a puncture device, including a puncture platform. Several evenly distributed puncture molds are fixedly connected to the lower surface of the puncture platform. The bottom sides of the puncture molds are arranged in a needle shape. Corresponding ejection blocks are slidably connected between the several puncture molds and on the inner side of the puncture molds. An ejection structure is provided at the top of the puncture platform. The ejection structure includes a central ejection plate, which is located directly above the puncture platform. A second adjusting cylinder is fixedly connected to the upper surface of the puncture platform.

[0004] The above-mentioned piercing device can realize the feeding and transfer of rubber strips, but it still has shortcomings: when picking up the material, the piercing platform is first driven to press down by the first adjusting cylinder, and the unloading is achieved by the second adjusting cylinder controlling the ejector plate to move down. The feeding requires the cooperation of multiple cylinders, the drive structure is complex and costly, and the ejector plate pushes the rubber strip down and it falls during unloading, which can easily cause the rubber strip to shift in position. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a feeding device for a rubber strip cutting machine. The technical problem this utility model aims to solve is: how to balance the low cost of the drive components and the feeding accuracy of the device.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A feeding device for a rubber strip cutting machine includes a feeding seat and a plate-shaped transfer plate. The bottom surface of the transfer plate is fixed with a plurality of pins arranged at intervals with their tips pointing downwards. The device further includes a plate-shaped straightening plate with a plurality of through-holes. The straightening plate is fixedly connected below the feeding seat and has a gap between it and the feeding seat. The transfer plate is located between the feeding seat and the straightening plate, with the pins inserted downwards into the through-holes. A driving cylinder is fixedly mounted on the feeding seat, and the output end of the driving cylinder is connected downwards to the transfer plate. When the driving cylinder extends, the lower end of the pin extends out of the through-hole; when the driving cylinder retracts, the lower end of the pin is located within the through-hole.

[0008] The existing feeding seat can move vertically and horizontally. Pins on the transfer plate can pierce the rubber strip downwards, thus lifting the rubber strip and moving it with the feeding seat for transfer. By installing a smoothing plate below the feeding seat, the transfer plate is positioned within the space between the feeding seat and the smoothing plate. Simultaneously, the pins are inserted into the strip-shaped holes on the smoothing plate. When the feeding seat moves above the rubber strip, a drive cylinder can be controlled to move the transfer plate downwards, causing the lower end of the pins to extend out of the strip-shaped holes and pierce the rubber strip below. Afterwards, the feeding seat can be moved upwards and horizontally above the feeding area and then moved downwards to press the rubber strip tightly. Then, the drive cylinder is controlled to retract, causing the transfer plate to move upwards. The lower end of the pin retracts into the strip-shaped insertion hole, causing the rubber strip to be blocked by the edge of the strip-shaped insertion hole and pulled off. Since the rubber strip is still pressed by the stripping plate, the positional accuracy of the rubber strip can be guaranteed, making the feeding accurate. In addition, the entire feeding process can be reasonably facilitated by the extension and retraction of the same drive cylinder, which can complete the feeding operation and save component costs.

[0009] In the feeding device of the aforementioned rubber strip cutting machine, several vertically arranged guide columns are fixed on the upper side of the transfer plate, and the guide columns slide through the feeding seat. This helps to ensure the directional stability of the entire transfer plate's up-and-down movement through the guide columns, thus ensuring operational accuracy.

[0010] In the feeding device of the aforementioned rubber strip cutting machine, a guide sleeve is fixed to the upper side of the feeding seat, and the guide post passes through the guide sleeve. This ensures that the upper end of the guide post is still constrained and guided by the guide sleeve after it passes through the feeding seat, which helps to ensure the moving accuracy of the transfer plate.

[0011] In the feeding device of the aforementioned rubber strip cutting machine, the material-straightening plate is fixed by several vertically arranged connecting columns, which are arranged around the outer periphery of the material-transferring plate. This helps to ensure the connection strength between the material-straightening plate and the feeding seat, while effectively ensuring that the space between the two does not easily change around the perimeter, thereby stabilizing the movement space of the material-transferring plate and avoiding interference.

[0012] In the feeding device of the aforementioned rubber strip cutting machine, the pins are arranged in several rows, with the upper ends of the pins in each row integrally connected. This design integrates multiple rows of pins into a single component, resulting in higher strength, easier assembly, and ensuring the stability of the pin structure.

[0013] In the feeding device of the aforementioned rubber strip cutting machine, the drive cylinder is located on the upper side of the feeding seat. This helps to prevent the drive cylinder from encroaching on the space between the straightening plate and the feeding seat, ensuring that the space is kept within a reasonable size range, and preventing insufficient connection strength between the straightening plate and the feeding seat due to excessive spacing.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] The feeding device of this rubber strip cutting machine achieves feeding operation and saves the cost of drive components by making reasonable use of the extension and retraction of the same drive cylinder. At the same time, during the feeding process, the feeding plate can stably press the rubber strip on the feeding area. After the insertion pin is withdrawn, it moves upward again, which can ensure that the rubber strip detached from the feeding plate can maintain the accurate feeding position.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 As shown, the feeding device of this rubber strip cutting machine includes a feeding seat 1 and a plate-shaped transfer plate 2. Several rows of pins 3, with their tips pointing downwards and arranged at intervals, are fixed to the bottom surface of the transfer plate 2. The upper ends of each row of pins 3 are integrally connected. The feeding device also includes a plate-shaped straightening plate 4, which is fixed below the feeding seat 1 and has a gap between it and the feeding seat 1. The transfer plate 2 is located between the feeding seat 1 and the straightening plate 4. Four drive cylinders 5 are fixed on the feeding seat 1, located on its upper side. Four vertically arranged guide posts 6 are fixed to the upper side of the transfer plate 2, and the guide posts 6 slide through the feeding seat 1. A guide sleeve 7 is fixed to the upper side of the feeding seat 1, and the guide posts 6 pass through the guide sleeve 7. The straightening plate 4 is fixed by several vertically arranged connecting posts 8, which are arranged around the outer periphery of the transfer plate 2.

[0024] like Figure 2-4As shown, the material feeding plate 4 has several through strip-shaped insertion holes 41. The pins 3 are all inserted downwards into the strip-shaped insertion holes 41. The output end of the drive cylinder 5 is connected downwards to the material transfer plate 2. When the drive cylinder 5 extends, the lower end of the pins 3 extends out of the strip-shaped insertion holes 41.

[0025] like Figure 5 As shown, when the drive cylinder 5 retracts, the lower end of the pin 3 is located inside the strip-shaped socket 41.

[0026] During feeding, the feeding seat 1 moves above the rubber strip, and the drive cylinder 5 is controlled to move the transfer plate 2 downward. The lower end of the pin 3 extends out of the strip-shaped insertion hole 41 and pierces the rubber strip below. Then the feeding seat 1 can move upward and horizontally to the feeding area. Then the feeding seat 1 is controlled to move downward and press the rubber strip onto the feeding area through the stripping plate 4. Then the drive cylinder 5 is controlled to retract and move the transfer plate 2 upward. The lower end of the pin 3 retracts into the strip-shaped insertion hole 41, so that the rubber strip is blocked by the edge of the strip-shaped insertion hole 41 and stripped off. Finally, the feeding seat 1 is controlled to move upward to complete the separation.
