Description

Technical Field

[0001] This invention relates to the field of positioning structure technology, and in particular to a positioning structure for processing rubber products. Background Technology

[0002] In the field of rubber product processing, thin rubber products (typically referring to rubber sheets, rubber films, precision gaskets, etc. with a thickness of ≤2mm) have always presented technical challenges in terms of positioning and flattening due to their high flexibility and strict requirements for surface flatness. With the increasing demands for product precision from downstream applications (such as electronic equipment, medical devices, and precision instruments), traditional positioning structures are no longer sufficient to meet the dual requirements of "precise positioning + wrinkle-free flattening" for thin rubber products. Problems such as dimensional deviations, surface wrinkles, and edge damage frequently occur during processing, severely impacting product quality and production efficiency.

[0003] Traditional positioning structures (such as pin positioning and slot positioning) are mostly designed for thick or irregularly shaped rubber parts, and are insufficient for thin rubber products. For example, pin positioning requires pre-drilled positioning holes in the rubber part, but thin rubber is prone to tearing at the hole edges after drilling; slot positioning, due to the flexibility of rubber, is prone to "wrinkling after insertion", and the positioning deviation usually exceeds ±0.5mm, which cannot meet the processing requirements of products such as electronic sealing gaskets (accuracy requirement ±0.1mm) and medical rubber patches (accuracy requirement ±0.05mm). Therefore, this application proposes a positioning structure for processing rubber products. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that thin rubber products are prone to wrinkling before processing, and to propose a positioning structure for processing rubber products.

[0005] The technical solution of the present invention: A positioning structure for processing rubber products, including a working plate, and further comprising: The mounting column is fixedly mounted on the work plate. A cylinder is slidably mounted on one side of the mounting column. The piston rod of the cylinder is fixedly mounted on the mounting plate. The mounting plate is provided with a flattening mechanism for flattening the rubber product to be processed.

[0006] Optionally, the leveling mechanism includes fixed rods fixedly installed on both sides of the mounting plate, a track plate fixedly installed at one end of the fixed rods, a slider slidably installed inside the track plate, a slide plate slidably installed at the bottom of the slider, the bottom of the slide plate being arc-shaped, a first spring fixedly installed at the bottom of the slider, one end of the first spring being fixedly connected to the slide plate, and connecting plates hinged to both sides of the mounting plate, the connecting plates being hinged to the slide plate.

[0007] Optionally, a blower is fixedly installed on the mounting column, a guide pipe is fixedly installed on one side of the blower, a heating block is fixedly installed on the guide pipe, a first track frame is fixedly installed at the bottom of the mounting plate, a guide block is slidably installed on the first track frame, a first reciprocating screw is rotatably installed inside the first track frame, the first reciprocating screw is threadedly connected to the guide block, a guide cavity is fixedly installed at the bottom of the guide block, the guide cavity is hollow, one end of the guide pipe communicates with the guide cavity, multiple nozzles arranged at equal intervals are fixedly installed at the bottom of the guide cavity, a placement plate is fixedly installed on the working plate, the placement plate is hollow, multiple vent holes are opened at the top of the placement plate, and a connecting pipe is fixedly installed on the other side of the blower, one end of the connecting pipe communicates with the placement plate.

[0008] Optionally, a second track frame is fixedly installed on the work plate, a guide post is slidably installed on the second track frame, a second reciprocating screw is rotatably installed inside the second track frame, the second reciprocating screw is threadedly connected to the guide post, a long plate is fixedly installed on one side of the guide post, a cleaning plate is slidably installed on the bottom of the long plate, and a plurality of cleaning blocks arranged at equal intervals are fixedly installed on the bottom of the cleaning plate, the cleaning blocks being in contact with the placement plate.

[0009] Optionally, the track plate is provided with a groove, and the slider is located in the groove.

[0010] Optionally, a fixing plate is fixedly installed on one side of the working plate, and the fixing plate is fixedly connected to the blower.

[0011] Optionally, a support plate is fixedly installed on one side of the mounting column, the support plate is fixedly connected to the cylinder, a positioning plate is fixedly installed on the cylinder, and a threaded rod is rotatably installed on the mounting column, the threaded rod being threadedly connected to the positioning plate.

[0012] Optionally, a first motor is fixedly installed on one side of the first track frame, and the output shaft of the first motor is fixedly connected to the first reciprocating lead screw.

[0013] Optionally, a second motor is fixedly installed on one side of the mounting column, and the output shaft of the second motor is fixedly connected to the threaded rod.

[0014] Optionally, a third motor is fixedly installed on one side of the second track frame, and the output shaft of the third motor is fixedly connected to the second reciprocating lead screw.

[0015] In summary, this application includes at least one of the following beneficial technical effects: This invention uses a starting cylinder to move a mounting plate downwards. A sliding plate hinged to the bottom of the mounting plate contacts the rubber product. As the mounting plate moves, the sliding plate moves to both sides, flattening the rubber product and achieving flattening before processing.

[0016] Furthermore, by starting the blower, air is drawn in through the vent on the placement plate via the connecting pipe on one side of the blower. At this time, the airflow on the surface of the placement plate moves inward, creating a negative pressure. The flattened rubber product is then adsorbed onto the placement plate, further improving the stability of the rubber product during processing and preventing it from moving. The drawn-in air is discharged from the blower via a guide pipe on one side, heated by the heating block, and then sprayed out from the nozzle at the bottom of the guide cavity. This, combined with the rotation of the first reciprocating screw, causes the guide block to move horizontally back and forth on the first track frame, making the nozzle on the guide cavity move together to dry the surface of the rubber product, preventing moisture from adhering and causing the rubber product to become sticky. At the same time, it cleans the surface of the rubber product before processing.

[0017] Furthermore, by reversing the start of the blower, air is drawn in from the nozzle, discharged through the connecting pipe into the placement plate, and then discharged through the vent. This is combined with the rotation of the second reciprocating screw, which drives the guide column to move horizontally back and forth on the second track frame. The guide column drives the long plate on one side to move together, and the cleaning block at the bottom of the long plate rubs back and forth against the vent, removing impurities. This, combined with the spray from the vent, improves the unblocking effect of the vent and prevents the vent from becoming clogged, thus affecting the adsorption effect on rubber products.

[0018] This invention provides a method for flattening and cleaning rubber products before processing, avoiding wrinkles that could affect the processing effect, improving processing quality, providing good fixation, high processing efficiency, and strong practicality. Attached Figure Description

[0027] Example 1 like Figure 1-2 As shown, the positioning structure for processing rubber products proposed in this invention includes a working plate 1 for placing the rubber products to be processed, and a mounting column 2. The mounting column 2 is fixedly installed on the working plate 1. A cylinder 7 is fixedly installed on one side of the mounting column 2. The piston rod of the cylinder 7 is fixedly installed on the mounting plate 8. When the cylinder 7 is started, the piston rod of the cylinder 7 drives the mounting plate 8 to move downward. The mounting plate 8 is provided with a flattening mechanism for flattening the rubber products to be processed. like Figure 3-4 As shown, this embodiment also includes a flattening mechanism, which includes fixed rods 20 fixedly installed on both sides of the mounting plate 8. A track plate 10 is fixedly installed at one end of the fixed rods 20. A slider 18 is slidably installed inside the track plate 10. A slide plate 9 is slidably installed at the bottom of the slider 18. The bottom of the slide plate 9 is arc-shaped. A spring 14 is fixedly installed at the bottom of the slider 18. One end of the spring 14 is fixedly connected to the slide plate 9. Connecting plates 15 are hinged to both sides of the mounting plate 8. The connecting plates 15 are hinged to the slide plate 9. When the cylinder 7 is activated, the piston rod of the cylinder 7 drives the mounting plate 8 to move downward. The mounting plate 8 drives the slide plate 9 at the bottom of the track plate 10 to contact the rubber product. Since the connecting plate 15 is hinged to the mounting plate 8, when the mounting plate 8 moves downward, it can squeeze the slide plate 9, causing the slide plate 9 to slide to both sides and flatten the rubber product. After processing, the cylinder 7 is reset, and the spring 14 rebounds, causing the slide plates 9 to move closer to each other, making it easier to flatten the rubber product again next time.

[0028] Example 2 like Figure 1, Figure 7 and Figure 8 As shown, a blower 4 is fixedly installed on the mounting column 2. A guide pipe 6 is fixedly installed on one side of the blower 4. A heating block 27 is fixedly installed on the guide pipe 6 to heat the air entering the guide pipe 6. The temperature is controlled at 40-60 degrees Celsius to prevent the rubber products from melting due to excessive temperature. A first track frame 17 is fixedly installed at the bottom of the mounting plate 8. A guide block 16 is slidably installed on the first track frame 17. A first reciprocating screw 33 is rotatably installed inside the first track frame 17. The first reciprocating screw 33 is threadedly connected to the guide block 16. A guide cavity 12 is fixedly installed at the bottom of the guide block 16. The guide cavity 12 is hollow. One end of the guide pipe 6 is connected to the guide cavity 12. Multiple nozzles 19 arranged at equal intervals are fixedly installed at the bottom of the guide cavity 12. A placement plate 24 is fixedly installed on the working plate 1. The placement plate 24 is hollow. Multiple ventilation holes 35 are opened on the top of the placement plate 24. A connecting pipe 25 is fixedly installed on the other side of the blower 4. One end of the connecting pipe 25 is connected to the placement plate 24. When the blower 4 is started, the connecting pipe 25 on one side of the blower 4 draws air in through the vent 35 on the placement plate 24. At this time, the airflow on the surface of the placement plate 24 moves inward, forming a negative pressure. The flattened rubber product is adsorbed on the placement plate 24, further improving the stability of the rubber product during processing and preventing it from moving. The drawn-in air is discharged from the blower 4 through the guide pipe 6, heated by the heating block 27, and then sprayed out by the nozzle 19 at the bottom of the guide cavity 12. In conjunction with the rotation of the first reciprocating screw 33, the first reciprocating screw 33 drives the guide block 16 to make horizontal reciprocating motion on the first track frame 17, so that the nozzle 19 on the guide cavity 12 moves together to dry the surface of the rubber product, preventing moisture from adhering and causing the rubber product to become sticky. At the same time, it cleans the surface of the rubber product before processing.

[0029] Example 3 like Figure 2-6As shown, a second track frame 26 is fixedly installed on the work plate 1. A guide post 32 is slidably installed on the second track frame 26. A second reciprocating screw 31 is rotatably installed inside the second track frame 26. The second reciprocating screw 31 is threadedly connected to the guide post 32. A long plate 28 is fixedly installed on one side of the guide post 32. A cleaning plate 29 is slidably installed on the bottom of the long plate 28. Multiple cleaning blocks 30 arranged at equal intervals are fixedly installed on the bottom of the cleaning plate 29. The cleaning blocks 30 are in contact with the placement plate 24. When it is necessary to unclog the vent holes 35 on the surface of the placement plate 24, the drum is reversed to start. The blower 4 draws air in from the nozzle 19, then discharges it through the connecting pipe 25 into the placement plate 24, and then out through the vent 35. In conjunction with the rotation of the second reciprocating screw 31, the second reciprocating screw 31 drives the guide column 32 to perform horizontal reciprocating motion on the second track frame 26. The guide column 32 drives the long plate 28 on one side to move together. The cleaning block 30 at the bottom of the long plate 28 rubs back and forth against the vent 35 to remove impurities. Combined with the spray from the vent 35, it improves the unblocking effect of the vent 35 and prevents the vent 35 from being blocked, thus affecting the adsorption effect on rubber products.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a groove 13 is provided on the track plate 10, and the slider 18 is located in the groove 13. A fixing plate 5 is fixedly installed on one side of the working plate 1, and the fixing plate 5 is fixedly connected to the blower 4. A support plate 3 is fixedly installed on one side of the mounting column 2, and the support plate 3 is fixedly connected to the cylinder 7. A positioning plate 21 is fixedly installed on the cylinder 7.

A first motor 11 is fixedly installed on one side of the first track frame 17, and the output shaft of the first motor 11 is fixedly connected to the first reciprocating screw 33. Next, the first motor 11 is started, and the output shaft of the first motor 11 drives the first reciprocating lead screw 33 to rotate. The second motor 23 is fixedly installed on one side of the mounting column 2, and the output shaft of the second motor 23 is fixedly connected to the threaded rod 22. The second motor 23 is started, and the output shaft of the second motor 23 drives the threaded rod 22 to rotate. The third motor 34 is fixedly installed on one side of the second track frame 26, and the output shaft of the third motor 34 is fixedly connected to the second reciprocating lead screw 31. The third motor 34 is started, and the output shaft of the third motor 34 drives the second reciprocating lead screw 31 to rotate.

[0031] Working principle: The rubber product to be processed is placed on the working plate 1. The cylinder 7 is started, and the piston rod of the cylinder 7 drives the mounting plate 8 to move downward. The mounting plate 8 drives the sliding plate 9 at the bottom of the track plate 10 to contact the rubber product. Since the connecting plate 15 is hinged to the mounting plate 8, the mounting plate 8 can squeeze the sliding plate 9 when it moves downward, causing the sliding plate 9 to slide to both sides and flatten the rubber product. The blower 4 is started, and the connecting pipe 25 on one side of the blower 4 draws air in through the vent 35 on the placement plate 24. At this time, the airflow on the surface of the placement plate 24 moves inward, forming a negative pressure. The flattened rubber product is adsorbed on the placement plate 24, further improving the stability of the rubber product during processing and preventing movement. The drawn-in air is discharged from the side of the blower 4 through the guide pipe 6, heated by the heating block 27, and then sprayed out by the nozzle 19 at the bottom of the guide cavity 12. In conjunction with the rotation of the first reciprocating screw 33, the first reciprocating screw 33 drives the guide block 16 to make horizontal reciprocating motion on the first track frame 17, so that the guide cavity The nozzles 19 on the 12 move together to dry the surface of the rubber products, preventing moisture from adhering and causing the rubber products to become sticky. At the same time, it cleans the surface of the rubber products before processing. When it is necessary to clear the vent holes 35 on the surface of the placement plate 24, the blower 4 is reversed and started. The blower 4 draws air in from the nozzles 19, and then discharges it into the placement plate 24 through the connecting pipe 25, and then out through the vent holes 35. In conjunction with the rotation of the second reciprocating screw 31, the second reciprocating screw 31 drives the guide column 32 to move horizontally back and forth on the second track frame 26. The guide column 32 drives the long plate 28 on one side to move together. The cleaning block 30 at the bottom of the long plate 28 rubs back and forth against the vent holes 35 to remove impurities. Combined with the spray from the vent holes 35, it improves the clearing effect of the vent holes 35, and avoids the vent holes 35 from being blocked, which affects the adsorption effect on the rubber products. It realizes the flattening and cleaning of the rubber products before processing, avoids wrinkles that affect the processing effect, improves the processing quality, has a good fixing effect, high processing efficiency, and strong practicality.
