An automatic rubber winding device

Abstract

This utility model discloses an automatic rubber winding device, including a work frame with symmetrically arranged processing rollers inside. Sleeves are symmetrically arranged below the processing rollers inside the work frame, with sliding plates slidably connected within each sleeve. A spring connects the sliding plate to the sleeve. Support rods are connected to the ends of the sliding plates away from the springs, and semi-circular lower support rings are connected to the upper ends of the support rods. A semi-circular upper retaining ring is rotatably connected above the semi-circular lower support rings. A take-up roller is positioned between the support rods. Moving the take-up roller away from the processing rollers causes the sliding plate to move out of the sleeves. The movement of the sliding plate pulls the springs, causing them to extend and store restoring force. Furthermore, the sliding plate, in conjunction with a second limiting rod and a groove, ensures the stability of the take-up roller. Through the cooperation of the sleeves, sliding plate, and springs, manual labor is saved during the winding of silicone rubber, ensuring the stability of the take-up roller and guaranteeing the uniformity of the winding process.

Description

Technical Field

[0001] This utility model belongs to the field of open mill technology, specifically relating to an automatic rubber winding device. Background Technology

[0002] Silicone rubber is a special synthetic rubber with silicon-oxygen bonds as the main chain and organic groups connected to the side chains. It combines the high and low temperature resistance of inorganic materials with the flexibility of organic materials and is widely used in aerospace, electronics, medical and health and daily life.

[0003] The open mill is a core piece of equipment commonly used in rubber processing. It continuously shears, squeezes, and folds rubber materials through two horizontally mounted, relatively rotating rollers, so that the raw rubber and various compounding agents are fully and evenly mixed. It has the characteristics of simple structure, flexible operation, and easy observation of the mixing state.

[0004] Patent application CN218196202U discloses an open mill, which facilitates the placement and unwinding of film through the coordinated use of a mounting plate, guide roller, winding drum, film applicator, fixing cone, circular plate, and spring, making it convenient for winding. While this open mill can place and unwind film, in actual use, when winding the processed silicone, the operator needs to hold the winding roller close to the open mill roller and wrap the end of the silicone around the outside of the winding roller, causing the open mill roller to rotate for winding. During winding, the silicone on the outside of the winding roller becomes increasingly thick, requiring the operator to adjust their position accordingly. Furthermore, the silicone on the outside of the winding roller becomes increasingly heavy, making it difficult for the operator to handle the winding roller and adjust their position, sometimes even resulting in the winding roller falling. This leads to high labor intensity, makes it difficult to guarantee the stability of the winding roller, and consequently, the uniformity of the silicone winding. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the high labor intensity during silicone winding leads to the inability to guarantee the stability of the winding roller and the uniformity of silicone winding, and to provide an automatic silicone winding device.

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

[0007] An automatic glue-winding device includes a work frame with symmetrically arranged processing rollers inside. Sleeves are symmetrically arranged below the processing rollers inside the work frame. A sliding plate is slidably connected inside each sleeve, and a spring connects the sliding plate to the sleeve. Support rods are connected to the ends of the sliding plates away from the springs. Semicircular lower support rings are connected to the upper ends of the support rods. A semicircular upper retaining ring is rotatably connected above the semicircular lower support ring. A take-up roller is arranged between the support rods. Round rods are connected to the middle of both ends of the take-up roller, positioned between the semicircular lower support ring and the semicircular upper retaining ring. External plates are connected to the ends of both the semicircular lower support ring and the semicircular upper retaining ring away from the processing rollers. A rotating rod is rotatably connected to the middle of the upper part of the lower external plate. A fixed pressure block is connected to the upper end of the rotating rod. Through holes are provided on the upper external plate corresponding to the positions of the rotating rod and the fixed pressure block, with the rotating rod located within the through holes.

[0008] Preferably, the outer side of the slide plate is connected to symmetrically arranged slide rods, and the sleeve is provided with symmetrical slide rails corresponding to the positions of the slide rods, and the slide rods are slidably connected in the slide rails.

[0009] Preferably, a second limiting rod is provided at the position corresponding to the support rod inside the work frame, and a limiting groove is opened at the position corresponding to the second limiting rod on the support rod. The second limiting rod is slidably connected in the limiting groove. Sliding grooves are opened at both ends of the work frame corresponding to the second limiting rod, and the second limiting rod is slidably connected in the sliding grooves.

[0010] Preferably, an outer ring is connected to the outer side of the round rod at the position corresponding to the lower semicircular support ring and the upper semicircular retaining ring. A ring groove is opened at the position corresponding to the outer ring on the lower semicircular support ring and the upper semicircular retaining ring, and the outer ring is rotatably connected in the ring groove.

[0011] Preferably, the end of the sleeve furthest from the support rod is threaded with a first bidirectional lead screw, one end of which passes through the work frame and is connected to a motor fixed to the work frame.

[0012] Preferably, a limit block is connected to the middle of the upper surface of the sleeve, and a first limit rod is connected to the position of the limit block inside the working frame, and the first limit rod is slidably connected to the limit block.

[0013] Preferably, the upper surface of the work frame is connected to symmetrically arranged supports, and a second bidirectional lead screw is rotatably connected between the supports. The outer side of the second bidirectional lead screw is threadedly connected to symmetrically arranged movable plates. Each movable plate is provided with a baffle, and the upper surface of each baffle is connected to a symmetrically arranged threaded rod, which is threadedly connected to the movable plate.

[0014] Preferably, the end of the first bidirectional lead screw away from the motor passes through the work frame and is connected to the first sprocket, and the end of the second bidirectional lead screw away from the motor passes through the support and is connected to the second sprocket. A chain meshes between the first sprocket and the second sprocket.

[0015] The beneficial effects of this utility model are:

[0016] 1) After the take-up roller is installed, the operator first rolls the end silicone rubber to the outside of the take-up roller and ensures that the take-up roller and the processing roller press the silicone rubber together. Then, the processing roller is started to rotate, which drives the take-up roller to rotate. During the rotation, the take-up roller winds up the silicone rubber. During the winding process, the silicone rubber on the outside of the take-up roller becomes thicker and thicker, causing the take-up roller to move away from the processing roller. The movement of the take-up roller causes the slide plate to move out of the sleeve. When the slide plate moves, it pulls the spring, which extends and stores the restoring force. When the slide plate moves, it works with the second limit rod and the slide groove to ensure the stability of the take-up roller. Through the cooperation of the sleeve, slide plate and spring, the labor intensity is reduced when winding the silicone rubber, and the stability of the take-up roller is ensured, thereby ensuring the uniformity of winding.

[0017] 2) When the silicone rubber is finished and winding is required, start the first motor. The first motor drives the first bidirectional lead screw to rotate. The rotation of the first bidirectional lead screw causes the two sleeves to move closer to each other. The movement of the sleeves causes the slide plate, support rod, lower semicircular support ring, and upper semicircular retaining ring to move. After the lower semicircular support ring and the upper semicircular retaining ring move to the designated position, the winding roller can be installed between the lower semicircular support ring and the upper semicircular retaining ring to fix the winding roller. During the rotation of the first bidirectional lead screw, it works with the first sprocket, the second sprocket, and the chain to move the moving plate and the baffle closer to each other, thereby determining the width of the silicone rubber winding. After the position of the sleeve and the moving plate is adjusted, the winding work can be carried out. After the winding work is completed, start the motor again to move the sleeve and the moving plate to a position close to the inner wall of the work frame to avoid affecting the subsequent silicone rubber processing. The position of the sleeve and the moving plate can be adjusted synchronously according to the required width of the silicone rubber, improving synchronization and adaptability.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] Please see Figure 1 - Figure 5 As shown, an automatic rubber winding device includes a work frame 1, in which processing rollers 11 are arranged symmetrically. The processing rollers 11 are used to process silicone rubber.

[0034] Inside the work frame 1, below the processing roller 11, there are symmetrically arranged sleeves 2. A slide plate 21 is slidably connected inside the sleeve 2. The sleeve 2 is used to store the slide plate 21, and the slide plate 21 is used to adjust the position of the take-up roller 32.

[0035] The outer side of the slide plate 21 is connected to symmetrically arranged slide rods 23. The sleeve 2 is provided with symmetrical slide rails 24 corresponding to the position of the slide rods 23. The slide rods 23 are slidably connected in the slide rails 24. Through the cooperation of the slide rods 23 and the slide rails 24, the movement position of the slide plate 21 can be limited.

[0036] A spring 22 is connected between the slide plate 21 and the sleeve 2, and the spring 22 is used to reset the slide plate 21.

[0037] The end of the slide plate 21 away from the spring 22 is connected to a support rod 25, which is used to support the semi-circular lower support ring 3.

[0038] A second limiting rod 54 is provided in the work frame 1 at the position corresponding to the support rod 25. A limiting groove 55 is opened at the position of the support rod 25 corresponding to the second limiting rod 54. The second limiting rod 54 is slidably connected in the limiting groove 55. A sliding groove 56 is opened at both ends of the work frame 1 corresponding to the second limiting rod 54. The second limiting rod 54 is slidably connected in the sliding groove 56. Through the cooperation of the second limiting rod 54 and the sliding groove 56, the end of the slide plate 21 away from the sleeve 2 can be supported, and the stability of the slide plate 21 can be ensured when the slide plate 21 is moved out of the sleeve 2.

[0039] The upper end of each support rod 25 is connected to a semi-circular lower support ring 3, which is used to support and fix the take-up roller 32.

[0040] A semi-circular upper retaining ring 31 is rotatably connected above the semi-circular lower support ring 3. The semi-circular upper retaining ring 31 is used to limit the winding roller 32, ensure the stability of the winding roller 32, and prevent the winding roller 32 from falling out of the semi-circular lower support ring 3.

[0041] A take-up roller 32 is provided between the support rods 25. The take-up roller 32 is used to take up the silicone rubber after the processing is completed.

[0042] Both ends of the take-up roller 32 are connected to a round rod 33. The round rod 33 is located between the lower semicircular support ring 3 and the upper semicircular retaining ring 31. The round rod 33 is used to support the take-up roller 32.

[0043] An outer ring 34 is connected to the outer side of the round rod 33 at the positions corresponding to the lower semicircular support ring 3 and the upper semicircular retaining ring 31. An annular groove 35 is opened at the positions corresponding to the outer ring 34 of the lower semicircular support ring 3 and the upper semicircular retaining ring 31. The outer ring 34 is rotatably connected in the annular groove 35. Through the cooperation between the outer ring 34 and the annular groove 35, the positions of the round rod 33 and the winding roller 32 can be fixed to prevent the winding roller 32 from shifting during the winding of silicone rubber.

[0044] The lower semicircular support ring 3 and the upper semicircular retaining ring 31 are both connected to an outer plate 4 at the ends away from the processing roller 11. The outer plate 4 is used to assist in connecting the lower semicircular support ring 3 and the upper semicircular retaining ring 31.

[0045] A rotating rod 41 is rotatably connected to the upper center of the lower outer plate 4. A fixed pressure block 43 is connected to the upper end of the rotating rod 41. The rotating rod 41 is used to adjust the angle of the fixed pressure block 43. The fixed pressure block 43 is used to press the semi-circular upper retaining ring 31 to prevent the semi-circular upper retaining ring 31 from rotating.

[0046] The outer plate 4 located above has through holes 42 at the positions corresponding to the rotating rod 41 and the fixed pressure block 43. The rotating rod 41 is located in the through hole 42, and the through hole 42 is used for the rotating rod 41 and the fixed pressure block 43 to pass through.

[0047] The height of the rotating rod 41 is equal to the thickness of the outer plate 4. This setting ensures that the fixing block 43 can press the semi-circular upper retaining ring 31 tightly.

[0048] In practical use, after the silicone rubber is processed, rotate the upper semicircular retaining ring 31 to move it away from the lower semicircular support ring 3. After rotation, align the outer ring 34 with the ring groove 35 and insert it so that the round rod 33 is located between the upper semicircular retaining ring 31 and the lower semicircular support ring 3. After placement, rotate the upper semicircular retaining ring 31 to bring it closer to the lower semicircular support ring 3. After it gets close, screw the fixing block 43 so that the lower surface of the fixing block 43 contacts the upper surface of the outer plate 4 above. After contact, the fixing block 43 presses the upper semicircular retaining ring 31 tightly, thereby installing and fixing the take-up roller 32, ensuring the stability of the take-up roller 32, and preventing the take-up roller 32 from falling out of the lower semicircular support ring 3.

[0049] After the take-up roller 32 is installed, the operator first rolls the end silicone rubber to the outside of the take-up roller 32 and ensures that the take-up roller 32 and the processing roller 11 press the silicone rubber together. Then, the processing roller 11 is started and rotated. The rotation of the processing roller 11 drives the take-up roller 32 to rotate. During the rotation, the take-up roller 32 rolls up the silicone rubber. During the winding process, the silicone rubber on the outside of the take-up roller 32 becomes thicker and thicker, causing the take-up roller 32 to move away from the processing roller 11. The movement of the take-up roller 32 causes the slide plate 21 to move out of the sleeve 2. When the slide plate 21 moves, it pulls the spring 22, causing the spring 22 to extend and store the restoring force. When the slide plate 21 moves, it cooperates with the second limit rod 54 and the slide groove 56 to ensure the stability of the take-up roller 32. Through the cooperation of the sleeve 2, the slide plate 21 and the spring 22, the labor intensity is reduced when winding the silicone rubber, and the stability of the take-up roller 32 can be ensured, thereby ensuring the uniformity of winding.

[0050] After the silicone rubber is wound up, tighten the fixing block 43 so that the fixing block 43 aligns with the through hole 42. After alignment, rotate the upper semicircular retaining ring 31 so that the upper semicircular retaining ring 31 moves away from the lower semicircular support ring 3, so that the round rod 33 is no longer fixed. Then the winding roller 32 can be removed. After the winding roller 32 is removed, the spring 22 loses its tension. Under the action of the spring 22's restoring force, the slide plate 21 returns to its original position, preparing for the subsequent winding of silicone rubber.

[0051] The end of the sleeve 2 away from the support rod 25 is threaded with a first double-acting screw 5, which is used to adjust the position of the sleeve 2.

[0052] One end of the first bidirectional lead screw 5 passes through the work frame 1 and is connected to the motor 51 fixed on the work frame 1. The motor 51 is used to drive the first bidirectional lead screw 5 to rotate.

[0053] Limiting blocks 52 are connected to the middle of the upper surface of the sleeve 2. A first limiting rod 53 is connected to the position of the limiting block 52 in the working frame 1. The first limiting rod 53 is slidably connected to the limiting block 52. Through the cooperation of the limiting block 52 and the first limiting rod 53, the position of the sleeve 2 can be limited to prevent the sleeve 2 from deflecting during movement.

[0054] The upper surface of the work frame 1 is connected to symmetrically arranged supports 6, which are used to support and fix the second bidirectional lead screw 61.

[0055] A second bidirectional lead screw 61 is rotatably connected between the supports 6, and the second bidirectional lead screw 61 is used to adjust the position of the moving plate 62.

[0056] The second bidirectional lead screw 61 has a symmetrically arranged movable plate 62 connected to its outer thread. The movable plate 62 is used to install the baffle 63.

[0057] Each movable plate 62 is equipped with a baffle 63, which is used to block the silicone rubber, allowing the silicone rubber to enter between the baffles 63, thereby determining the width of the processed silicone rubber.

[0058] The upper surface of the baffle 63 is connected with symmetrically arranged threaded rods 64. The threaded rods 64 are threadedly connected to the movable plate 62. Through the cooperation of the threaded rods 64, the position of the baffle 63 can be fixed, and the height of the baffle 63 can be adjusted.

[0059] The end of the first bidirectional lead screw 5 away from the motor 51 passes through the work frame 1 and is connected to the first sprocket 7. The end of the second bidirectional lead screw 61 away from the motor 51 passes through the support 6 and is connected to the second sprocket 71. A chain 72 meshes between the first sprocket 7 and the second sprocket 71. Through the cooperation of the first sprocket 7, the second sprocket 71 and the chain 72, the first bidirectional lead screw 5 and the second bidirectional lead screw 61 can rotate synchronously.

[0060] In practical use, when the silicone rubber needs to be wound up after processing, the first motor 51 is started. The first motor 51 drives the first bidirectional lead screw 5 to rotate. The rotation of the first bidirectional lead screw 5 causes the two sleeves 2 to move closer to each other. The movement of the sleeves 2 causes the slide plate 21, support rod 25, lower semicircular support ring 3, and upper semicircular retaining ring 31 to move. After the lower semicircular support ring 3 and the upper semicircular retaining ring 31 move to the designated position, the winding roller 32 can be installed between the lower semicircular support ring 3 and the upper semicircular retaining ring 31 to fix the winding roller 32. During the rotation of the first bidirectional lead screw 5... The first sprocket 7, the second sprocket 71, and the chain 72 work together to move the movable plate 62 and the baffle 63 closer together, thereby determining the width of the silicone rubber winding. After the position of the sleeve 2 and the movable plate 62 is adjusted, the winding work can be carried out. After the winding work is completed, the motor 51 is started again to move the sleeve 2 and the movable plate 62 to a position close to the inner wall of the work frame 1 to avoid affecting the subsequent processing of silicone rubber. The position of the sleeve 2 and the movable plate 62 can be adjusted synchronously according to the required width of the silicone rubber, improving synchronization and adaptability.
