Description

Technical Field

[0001] This utility model relates to the field of foam tape feeding technology, specifically a feeding device for the production of double-sided laminated foam tape. Background Technology

[0002] Currently, foam tape is made by coating both sides of EVA or PE foam with solvent-based (or hot-melt) pressure-sensitive adhesive and then covering it with release paper. It has the functions of sealing and shock absorption, and has excellent sealing performance, resistance to compression deformation, flame retardancy, and wettability.

[0003] According to the announcement number CN218753873U, a feeding device for foam tape production includes a device body. A first traction roller and a second traction roller are vertically mounted at one end of the device body. Rotating grooves are formed on both side walls of the device body, and connecting shafts are installed within these grooves. Annular grooves are formed at both ends of the connecting shafts. Connecting seats are provided at both ends of the device body. Arc-shaped fixing plates are coaxially rotatably connected to the connecting seats. Two first shafts are inserted into the arc-shaped fixing plates. Arc-shaped locking blocks are fixedly connected to the first shafts. First springs are sleeved on the first shafts. Buckles are provided at the ends of the arc-shaped fixing plates. Buttons are provided on the side walls of the device body. A rotating cavity is provided within the device body, and an arc-shaped fixing plate fixing mechanism is provided within the rotating cavity. This utility model employs a fixing mechanism to secure the connecting shafts, preventing them from falling off during rotation.

[0004] The above-mentioned device fixes the connecting shaft to prevent it from falling off when rotating, and has a certain degree of practicality. According to the instruction manual and the attached drawings, the distance between the two sets of traction rollers of the device is fixed. However, the foam tape is made of soft material. If the distance is too large, the compression force will be insufficient, which will cause the feeding to slip and affect the feeding. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for the production of double-sided laminated foam tape, which addresses the problem that the spacing between the two sets of traction rollers in the device is fixed, while the foam tape is made of soft material and the insufficient extrusion pressure when the spacing is too large will cause the material to slip and affect the feeding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for producing double-sided laminated foam tape, comprising a traction roller one and a traction roller two disposed inside the feeding device body. A through groove is provided at one end of the feeding device body. A connecting block one is rotatably connected to one end of the traction roller one. A threaded rod is rotatably connected inside the through groove, and the threaded rod is threadedly connected to the connecting block one. A limit gear is rotatably connected to the top of the feeding device body. A rotating handle is fixedly installed at the top of the limit gear. A cavity is provided inside the feeding device body. A sliding groove is provided at one end of the feeding device body, and the sliding groove is connected to the cavity. A connecting block two is slidably connected inside the sliding groove. The output shaft at one end of the traction roller one is rotatably connected to the connecting block two.

[0007] As a further embodiment of this utility model: a bevel gear is fixedly installed on the output shaft of the traction roller, an L-shaped fixing plate is fixedly installed on the top of the connecting block, a hollow connecting sleeve is rotatably connected to the bottom of the L-shaped fixing plate, and a bevel gear is fixedly installed on the bottom of the hollow connecting sleeve. The bevel gear and the bevel gear mesh with each other. A drive shaft is rotatably connected inside the cavity, and the drive shaft is connected through the hollow connecting sleeve.

[0008] As a further embodiment of this utility model: a bevel gear three is fixedly installed on the output shaft at one end of the traction roller two, and a bevel gear four is fixedly installed on the outer periphery of the drive shaft, and the bevel gear four is meshed with the bevel gear three.

[0009] As a further embodiment of this utility model: the hollow connecting sleeve is symmetrically provided with sliding grooves inside, the drive shaft is symmetrically fixedly installed with sliding rods on its outer periphery, and the sliding rods are adapted to the sliding grooves; the top of the feeding device body is fixedly installed with a rotating motor, and the output shaft at the bottom of the rotating motor is fixedly installed with the drive shaft.

[0010] As a further improvement of this utility model: both the sliding groove and the through groove are symmetrically provided with guide grooves, and both ends of the connecting block two and the connecting block one are symmetrically fixed with guide blocks, and the guide blocks are adapted to the guide grooves.

[0011] As a further embodiment of this utility model: a rotating seat is fixedly installed at the top of the feeding device body, and an L-shaped limiting rod is rotatably connected to one end of the rotating seat. The L-shaped limiting rod is adapted to the tooth groove of the limiting gear. A reset spring is fixedly installed at the top of the feeding device body, and the top of the reset spring is fixedly installed to the bottom of the L-shaped limiting rod.

[0012] As a further improvement of this utility model: a connecting shaft is provided at the top of the feeding device body, and a limiting mechanism for limiting the connecting shaft is provided at the top of the feeding device body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model only requires rotating the L-shaped limiting rod to release the limit, and then driving the threaded rod to rotate by rotating the handle, which can push the connecting block one and the connecting block two to slide along the through groove and the slide groove respectively, driving the traction roller one to move smoothly. It can accurately adapt to foam tapes of different thicknesses, avoiding damage to soft tapes due to too small a gap, and preventing insufficient extrusion pressure due to too large a gap, thus reducing the risk of feeding slippage from the root and having strong adaptability. After adjustment, the L-shaped limit rod is released, and the reset spring automatically pulls it back to its original position, engaging with the limit gear groove to quickly fix the threaded rod position. This locks the distance between traction roller one and traction roller two. The locking structure is stable and reliable, preventing distance deviation caused by vibration or other factors during feeding. It ensures that traction roller one and traction roller two always clamp the tape with a suitable distance, providing continuous protection for stable feeding. No additional manual fixing is required, improving operational efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0018] Reference Figures 1 to 6 In this embodiment of the present invention, a feeding device for producing double-sided laminated foam tape includes a traction roller 2 and a traction roller 3 disposed inside the feeding device body 1. A through groove 4 is provided at one end of the feeding device body 1. A connecting block 5 is rotatably connected to one end of the traction roller 2. A threaded rod 6 is rotatably connected inside the through groove 4, and the threaded rod 6 is threadedly connected to the connecting block 5. A limit gear 7 is rotatably connected to the top of the feeding device body 1. A rotating handle 8 is fixedly installed on the top of the limit gear 7. A cavity 12 is provided inside the feeding device body 1. A sliding groove 13 is provided at one end of the feeding device body 1, and the sliding groove 13 is connected to the cavity 12. A connecting block 14 is slidably connected inside the sliding groove 13. The output shaft at one end of the traction roller 2 is rotatably connected to the connecting block 14.

[0019] The above-mentioned scheme is adopted as follows: the feeding device body 1, traction roller 1 2, and traction roller 2 3 are all prior art referenced in the prior art documents and are not described in detail in this application. The smooth inner wall of the through groove 4 provides rotation space for the threaded rod 6 (made of high-strength alloy steel, chrome-plated for rust prevention, and with high thread precision). The connecting block 1 5 is made of wear-resistant alloy material and is rotatably connected to one end of the traction roller 1 2 via a bearing. The internal thread is precisely matched with the threaded rod 6. The limiting gear 7 is made of high-strength alloy steel, and the tooth surface is hardened to improve wear resistance. It is fixed to the threaded rod 6 by a key connection. The rotating handle 8 is made of engineering plastic wrapped around a metal core, with anti-slip texture on the surface. It is welded and fixed to the eccentric end of the top of the limiting gear 7. The cavity 12 and the slide 13 are the internal structures of the feeding device body 1, and their materials are consistent with each other. The smooth inner wall of the chute 13 ensures that the connecting block 14 (made of wear-resistant alloy with a polished surface) slides smoothly. The connecting block 14 and the output shaft at one end of the traction roller 2 are connected by a bearing to ensure that the traction roller 2 can rotate flexibly. The advantage of this structure is that rotating the handle 8 drives the limit gear 7 and the threaded rod 6 to rotate. By using the threaded engagement between the threaded rod 6 and the connecting block 5, the traction roller 2 is driven to slide along the chute 13 through the connecting block 14, thereby adjusting the distance between the traction roller 2 and the corresponding roller body to meet the conveying needs of materials of different thicknesses. The cooperation between the connecting block 14 and the chute 13 provides a stable guide for the traction roller 2, ensuring that its axis remains parallel during translation and avoiding material conveying deviation or damage due to tilting.

[0020] Reference Figures 1 to 6 A bevel gear 15 is fixedly installed on the output shaft of one end of the traction roller 2. An L-shaped fixing plate 16 is fixedly installed on the top of the connecting block 2 14. A hollow connecting sleeve 17 is rotatably connected to the bottom of the L-shaped fixing plate 16. A bevel gear 2 18 is fixedly installed on the bottom of the hollow connecting sleeve 17. The bevel gear 15 and the bevel gear 2 18 are meshed together. A drive shaft 19 is rotatably connected inside the cavity 12. The drive shaft 19 is connected through the hollow connecting sleeve 17. A bevel gear 3 22 is fixedly installed on the output shaft of one end of the traction roller 2 3. A bevel gear 4 23 is fixedly installed on the outer periphery of the drive shaft 19. The bevel gear 4 23 is meshed with the bevel gear 3 22. A sliding groove 21 is symmetrically opened inside the hollow connecting sleeve 17. A sliding rod 20 is symmetrically fixedly installed on the outer periphery of the drive shaft 19. The sliding rod 20 is adapted to the sliding groove 21. A rotating motor 26 is fixedly installed on the top of the feeding device body 1. The output shaft of the rotating motor 26 is fixedly installed on the bottom of the drive shaft 19. The above scheme is adopted: bevel gear 15, bevel gear 28, bevel gear 32, and bevel gear 423 are all made of high-strength alloy steel, and the tooth surface is carburized and quenched, resulting in high meshing accuracy and strong wear resistance. The L-shaped fixing plate 16 is made of high-strength alloy steel and is fixed to the connecting block 24 (made of wear-resistant alloy material) by welding, resulting in a stable structure. The hollow connecting sleeve 17 is made of wear-resistant alloy steel with a smooth inner wall and is rotatably connected to the L-shaped fixing plate 16 through bearings to ensure smooth rotation. The drive shaft 19 is made of high-strength alloy steel with a chrome-plated surface for rust prevention and is rotatably connected to the cavity 12 through bearings. The sliding groove 21 is opened inside the hollow connecting sleeve 17. The sliding rod 20 is made of the same material as the drive shaft 19, with a smooth surface that precisely matches the sliding groove 21. The rotating motor 26 is a servo motor with stable output torque and is fixed to the top of the feeding device body 1 by bolts. The output shaft and the drive shaft 19 are fixed by a coupling. The advantage of this structure is that the rotating motor 26 drives the drive shaft 19 to rotate, and the sliding... The cooperation between rod 20 and sliding groove 21 drives hollow connecting sleeve 17 to rotate synchronously, causing bevel gear 2 18 to mesh with bevel gear 15, driving traction roller 1 2 to rotate. At the same time, drive shaft 19 drives traction roller 2 3 to rotate through the meshing of bevel gear 4 23 and bevel gear 3 22, realizing synchronous reverse rotation of traction roller 1 2 and traction roller 2 3, ensuring stable material conveying. When traction roller 1 2 slides along sliding groove 13 to adjust the spacing, hollow connecting sleeve 17 moves synchronously with connecting block 2 14, and sliding rod 20 slides along sliding groove 21. This ensures that the power transmission between drive shaft 19 and hollow connecting sleeve 17 is not affected, and does not restrict the position adjustment of traction roller 1 2. The transmission of bevel gear 1 15, bevel gear 2 18, bevel gear 3 22 and bevel gear 4 23 can change the direction of force transmission, so that the power of drive shaft 19 is efficiently distributed to traction roller 1 2 and traction roller 2 3. The meshing transmission between them ensures that the speed of traction roller 1 2 and traction roller 2 3 is matched, avoiding relative slippage during material conveying that could cause damage.

[0021] Reference Figures 1 to 6 Both the sliding groove 13 and the through groove 4 are symmetrically provided with guide grooves 24. Both ends of the connecting block 2 14 and the connecting block 1 5 are symmetrically fixed with guide blocks 25, and the guide blocks 25 are adapted to the guide grooves 24. The above solution is adopted: the inner wall of the guide groove 24 is ground to make the surface smooth and highly parallel. The edge of the groove is rounded to avoid scratching the guide block 25. The guide block 25 is made of the same material as the connecting block 24 and the connecting block 15. It is fixed to both ends by welding. The surface is polished to reduce the coefficient of sliding friction and form a precise clearance fit with the guide groove 24. The advantage of this structure is that when the connecting block 24 and the connecting block 15 drive the traction roller 2 to slide along the slide groove 13 and the through groove 4, the guide block 25 slides synchronously along the guide groove 24, providing double precise guidance for the translation of the traction roller 2, restricting it to only move in a straight line, and avoiding the tilting, twisting or deviation of the traction roller 2 due to the thread gap between the threaded rod 6 and the connecting block 15 or uneven force. It ensures that the axes of the traction roller 2 and the traction roller 23 always remain parallel, and prevents the material from shifting, wrinkling or surface damage due to the lateral force generated by the non-parallelism of the two rollers during material conveying.

[0022] Reference Figures 1 to 6 A rotating seat 9 is fixedly installed at the top of the feeding device body 1, and an L-shaped limiting rod 10 is rotatably connected to one end of the rotating seat 9. The L-shaped limiting rod 10 is adapted to the tooth groove of the limiting gear 7. A reset spring 11 is fixedly installed at the top of the feeding device body 1, and the top of the reset spring 11 is fixedly installed at the bottom of the L-shaped limiting rod 10. The above-mentioned scheme is adopted as follows: the rotating seat 9 is made of high-strength alloy steel and is fixed to the top of the feeding device body 1 (high-strength alloy steel) by welding to ensure stable support. The L-shaped limit rod 10 is made of wear-resistant alloy material, and one end is rotatably connected to the rotating seat 9 through a rotating shaft. The contact end with the tooth groove of the limit gear 7 (high-strength alloy steel, with tooth surface quenching treatment) is hardened to ensure precise meshing. The return spring 11 is made of high-elasticity spring steel material with stable elasticity. Both ends are welded and fixed to the top of the feeding device body 1 and the bottom of the L-shaped limit rod 10, respectively, to ensure uniform force distribution. The advantage of this structure is that, under normal conditions, the return spring 11 causes the L-shaped limit rod 10 to be embedded in the limit position. The tooth groove of gear 7 restricts the rotation of the limiting gear 7, thereby fixing the position of the threaded rod 6 and the connecting block 5. This prevents the threaded rod 6 from rotating unexpectedly due to force during the feeding process of the traction roller 2, ensuring the stability of the distance between the traction roller 2 and the traction roller 3. This avoids stretching or wrinkling caused by changes in the distance during material conveying. When it is necessary to adjust the distance between the traction rollers, rotate the L-shaped limiting rod 10 to stretch the reset spring 18 so that it disengages from the tooth groove of the limiting gear 7. Then, the limiting gear 7 and the threaded rod 6 can be rotated by rotating the handle 8 to make the adjustment. After the adjustment is completed, release the L-shaped limiting rod 10, which will automatically reset and re-embed into the tooth groove under the action of the reset spring 11 to achieve locking.

[0023] Reference Figures 1 to 6 The top end of the feeding device body 1 is provided with a connecting shaft 27, and the top end of the feeding device body 1 is provided with a limiting mechanism 28 for limiting the connecting shaft 27. The above solution is adopted: the connecting shaft 27 and the limiting mechanism 28 are both prior art referenced in the prior art documents and are not described in detail in this application. The limiting mechanism 28 includes an arc block, an arc fixing plate, a connecting seat and a buckle, etc. The limiting mechanism 28 can limit the connecting shaft 27 and reduce the possibility of the connecting shaft 27 falling off.

[0024] The working principle of this utility model is as follows: When adjusting the distance between traction roller 2 and traction roller 3, first rotate the L-shaped limiting rod 10 on the rotating seat 9 at the top of the feeding device body 1 to disengage it from the tooth groove of the limiting gear 7. At the same time, stretch the return spring 11, rotate the rotating handle 8 at the top of the limiting gear 7, and drive the threaded rod 6, which is coaxial with the limiting gear 7, to rotate in the through groove 4. The threaded rod 6 is threadedly connected to the connecting block 5, pushing the connecting block 5 to slide along the through groove 4, thereby driving one end of traction roller 2 to move synchronously. The output shaft at the other end of traction roller 2 is rotatably connected to the connecting block 14. The connecting block 14 slides along the slide groove 13 with traction roller 2 until the distance between traction roller 2 and traction roller 3 is adapted to the thickness of the foam tape. If the distance is too small, it will avoid damaging the tape; if the distance is too large, it will prevent slippage. After adjustment, release the L-shaped limiting rod 10, and the return spring 11 will pull it back into the tooth groove of the limiting gear 7. The position of the fixed threaded rod 6 is fixed, and the distance between traction roller 1 2 and traction roller 2 3 is locked. When feeding, the rotating motor 26 at the top of the feeding device body 1 is started. Its output shaft drives the drive shaft 19 in the cavity 12 to rotate. The sliding rod 20 on the outer periphery of the drive shaft 19 is embedded in the sliding groove 21 inside the hollow connecting sleeve 17, which drives the hollow connecting sleeve 17 to rotate synchronously. When the hollow connecting sleeve 17 moves with the connecting block 2 14, the sliding rod 20 can slide along the sliding groove 21 without affecting the power transmission. The bevel gear 2 18 at the bottom of the hollow connecting sleeve 17 meshes with the bevel gear 1 15 on the output shaft of traction roller 1 2, which drives traction roller 1 2 to rotate. At the same time, the bevel gear 4 23 on the outer periphery of the drive shaft 19 meshes with the bevel gear 3 22 on the output shaft of traction roller 2 3, which drives traction roller 2 3 to rotate in the opposite direction. The two traction rollers cooperate to clamp the foam tape and deliver it stably, avoiding slippage caused by improper spacing and ensuring smooth feeding.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
