Description

Technical Field

[0001] This application relates to the field of paper rope production, and in particular to a paper rope discharge guide mechanism. Background Technology

[0002] Paper rope is an environmentally friendly type of rope made by mechanically or manually twisting strips of paper into a cord. It's a branch of rope production. Primarily used in packaging products such as paper bags, gift bundling, and product packaging. Besides packaging, paper rope is also widely used in furniture manufacturing, interior decoration, automotive parts, and many other fields.

[0003] The utility model patent with announcement number CN221253432U proposes a paper rope thread discharge guide mechanism, which includes a shell with an inner cavity and an open front, a front cover fixedly installed at the open position, a thread outlet hole opened on the front cover, a thread pressing device installed in the shell, a thread spool installed in the shell, and a tension adjustment device installed between the thread spool and the thread pressing device.

[0004] The aforementioned paper rope feeding guide mechanism uses a rotating screw to press the paper rope tightly with a first rotating roller and a second rotating roller, shaping the paper rope and making it straight. A rubber ring is provided to prevent the paper rope from disintegrating during pressing. However, manually rotating the screw makes it difficult to control the pressing force of the first and second rotating rollers on the paper rope. Excessive force may deform the rubber ring, damaging the paper rope and reducing its applicability. Utility Model Content

[0005] To address the aforementioned problems, this application provides a paper rope feeding guide mechanism.

[0006] The paper rope feeding guide mechanism provided in this application adopts the following technical solution:

[0007] A paper rope feeding guide mechanism includes a base plate. The base plate is provided with a straightening component for straightening the paper rope and a tensioning component for adjusting the tension of the paper rope. The straightening component includes two support plates fixedly connected to the upper surface of the base plate. A first pressure roller is rotatably connected between the two support plates. A U-shaped frame is provided above the first pressure roller. The two ends of the U-shaped frame pass through the top of the support plates and are slidably connected. A second pressure roller is rotatably connected to the inner cavity of the U-shaped frame. An L-shaped plate is fixedly connected to the upper surface of the base plate on one side of the support plates. Two sliding columns are fixedly connected to the top of the U-shaped frame. The tops of the sliding columns pass through the L-shaped plate and are slidably connected. A locking component is provided on the L-shaped plate for fixing the sliding columns.

[0008] By adopting the above technical solution, during use, the paper rope passes between the first and second pressing rollers, and then the sliding column is released, allowing the U-shaped frame to slide in the support plate under its own weight. This brings the second pressing roller closer to the first pressing roller, pressing the paper rope. Then, by activating the locking assembly, the sliding column is fixed, so that the paper rope is shaped and straightened as it passes through the first and second pressing rollers. This avoids the problem of manually turning the screw, which makes it difficult to control the pressing force of the first and second rotating rollers on the paper rope. If the force is too great, the rubber ring may deform, damaging the paper rope and reducing its applicability.

[0009] Preferably, the locking assembly includes a first through groove formed at the top of one side wall of the L-shaped plate, a bidirectional screw rotatably connected in the first through groove, two clamping plates threaded onto the bidirectional screw, the clamping plates being located on both sides of the sliding column, and a drive motor for driving the bidirectional screw to rotate is installed on one side wall of the L-shaped plate.

[0010] By adopting the above technical solution, the drive motor is started to drive the bidirectional screw to rotate, so that the two clamping plates move closer to each other under the restriction of the first through slot, clamping the sliding column. This can prevent the sliding column from moving during use and causing the second pressing roller to move.

[0011] Preferably, the tensioning assembly includes a fixed plate fixedly connected to the upper surface of the base plate on the other side of the support plate. Two first tensioning rollers are rotatably connected to one side wall of the fixed plate. A second through groove is formed above the two first tensioning rollers on one side wall of the fixed plate. A sliding block is slidably connected in the second through groove. A second tensioning roller is rotatably connected to one side wall of the sliding block. An adjusting bolt is provided at the top of the fixed plate. The screw end of the adjusting bolt passes through the fixed plate and is rotatably connected to the sliding block. The adjusting bolt is threadedly connected to the fixed plate.

[0012] By adopting the above technical solution, the paper rope can be pressed down and its tension adjusted by passing it between the first tension roller and the second tension roller, and then by rotating the adjusting bolt to make the sliding block slide in the second through groove, thereby moving the second tension roller.

[0013] Preferably, both the first pressing roller and the second pressing roller are fixedly connected with two rubber rings.

[0014] By adopting the above technical solution, the damage to the paper rope caused by the first and second pressing rollers during pressing can be reduced by the rubber ring.

[0015] Preferably, both the first tension roller and the second tension roller have annular guide grooves on their sidewalls.

[0016] By adopting the above technical solution, the annular guide groove can prevent the paper rope from moving left and right when passing through the first tension roller and the second tension roller, thereby improving the stability of the paper rope passing through.

[0017] Preferably, a spring is fixedly connected to the top of the U-shaped frame, and the end of the spring away from the U-shaped frame is fixedly connected to the L-shaped plate.

[0018] By adopting the above technical solution, the U-shaped frame can be pressed down by the spring, which increases the clamping force of the second clamping roller and the first clamping roller on the paper rope and prevents the clamping force from being too small.

[0019] Preferably, the two clamps are fixedly connected to the opposite sidewalls with rubber pads for increasing friction.

[0020] By adopting the above technical solution, the stability of the clamping plate in holding the sliding column can be improved by using the rubber pad.

[0021] Preferably, a limiting groove is formed at the top of one side wall of the fixing plate, and a limiting rod is fixedly connected in the limiting groove. The end of the clamping plate away from the bidirectional screw is sleeved on the limiting rod.

[0022] By adopting the above technical solution, the stability of the clamping plate can be improved by using the limiting rod, preventing the end of the clamping plate away from the bidirectional screw from bending when clamping the sliding column, which would reduce the clamping effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes a combination of structures such as a U-shaped frame, an L-shaped plate, and a sliding column. In use, the paper rope passes between the first and second pressure rollers, and then the sliding column is released, allowing the U-shaped frame to slide within the support plate under its own weight. This brings the second pressure roller closer to the first pressure roller, pressing the paper rope. Then, by activating the locking assembly, the sliding column is fixed, shaping the paper rope as it passes through the first and second pressure rollers, making it straight. This avoids the problem of manually turning the screw, which makes it difficult to control the pressing force of the first and second rotating rollers on the paper rope. Excessive force may deform the rubber ring, damaging the paper rope and reducing its applicability.

[0025] 2. By passing the paper rope between the first tension roller and the second tension roller, and then rotating the adjusting bolt to make the sliding block slide in the second through groove, the second tension roller can be moved to press down on the paper rope and adjust the tension of the paper rope.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a paper rope feeding guide mechanism.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A paper rope feeding guide mechanism includes a base plate 1. The base plate 1 is provided with a straightening component for straightening the paper rope and a tensioning component for adjusting the tension of the paper rope. The straightening component includes a support plate 2, a first pressing roller 3, a U-shaped frame 4, a second pressing roller 5, an L-shaped plate 6, and a sliding column 7.

[0034] Two support plates 2 are fixedly connected to the upper surface of the base plate 1. A first pressing roller 3 is rotatably connected between the two support plates 2. A U-shaped frame 4 is located above the first pressing roller 3. Both ends of the U-shaped frame 4 pass through the top of the support plate 2 and are slidably connected. A second pressing roller 5 is rotatably connected in the inner cavity of the U-shaped frame 4. An L-shaped plate 6 is fixedly connected to the upper surface of the base plate 1 and located on one side of the support plate 2. Two sliding columns 7 are fixedly connected to the top of the U-shaped frame 4. The top of each sliding column 7 passes through the L-shaped plate 6 and is slidably connected. The L-shaped plate 6 is provided with a locking assembly for fixing the sliding columns 7.

[0035] Reference Figure 1The locking assembly includes a first through groove 8 opened at the top of one side wall of the L-shaped plate 6. A bidirectional screw 9 is rotatably connected in the first through groove 8. Two clamping plates 10 are threadedly connected to the bidirectional screw 9. The clamping plates 10 are located on both sides of the sliding column 7. A drive motor 11 for driving the bidirectional screw 9 to rotate is installed on one side wall of the L-shaped plate 6. By starting the drive motor 11, the bidirectional screw 9 is driven to rotate, so that the two clamping plates 10 are brought closer to each other under the restriction of the first through groove 8, clamping the sliding column 7. This can prevent the sliding column 7 from moving during use and driving the second pressing roller 5 to move.

[0036] Reference Figure 1 The tensioning assembly includes a fixed plate 12 fixedly connected to the upper surface of the base plate 1 on the other side of the support plate 2. Two first tensioning rollers 13 are rotatably connected to one side wall of the fixed plate 12. A second through groove 14 is provided above the two first tensioning rollers 13 on one side wall of the fixed plate 12. A sliding block 15 is slidably connected in the second through groove 14. A second tensioning roller 16 is rotatably connected to one side wall of the sliding block 15. An adjusting bolt 17 is provided at the top of the fixed plate 12. The screw end of the adjusting bolt 17 passes through the fixed plate 12 and is rotatably connected to the sliding block 15. The adjusting bolt 17 is threadedly connected to the fixed plate 12. By passing the paper rope between the first tensioning rollers 13 and the second tensioning roller 16, and then rotating the adjusting bolt 17, the sliding block 15 slides in the second through groove 14, driving the second tensioning roller 16 to move. This can press down on the passing paper rope and adjust the tension of the paper rope.

[0037] Reference Figure 2 Two rubber rings 18 are fixedly connected to both the first pressing roller 3 and the second pressing roller 5. A groove is formed between each pair of rubber rings 18 for the paper rope to pass through. The rubber rings 18 can reduce the damage to the paper rope caused by the first pressing roller 3 and the second pressing roller 5 when pressing.

[0038] Reference Figure 1 and Figure 4 Both the first tension roller 13 and the second tension roller 16 have annular guide grooves 19 on their side walls. The annular guide grooves 19 can prevent the paper rope from moving left and right when passing through the first tension roller 13 and the second tension roller 16, thereby improving the stability of the paper rope passing through.

[0039] Reference Figure 1 A spring 20 is fixedly connected to the top of the U-shaped frame 4. The end of the spring 20 away from the U-shaped frame 4 is fixedly connected to the L-shaped plate 6. The spring 20 can press down the U-shaped frame 4 to increase the pressing force of the second pressing roller 5 and the first pressing roller 3 on the paper rope and prevent the pressing force from being too small.

[0040] Reference Figure 1 and Figure 3A rubber pad 21 for increasing friction is fixedly connected to one side wall of the two clamping plates 10 opposite to each other. The rubber pad 21 can improve the stability of the clamping plates 10 in clamping the sliding column 7.

[0041] Reference Figure 1 and Figure 3 A limiting groove 22 is provided at the top of one side wall of the fixed plate 12. A limiting rod 23 is fixedly connected in the limiting groove 22. The end of the clamping plate 10 away from the bidirectional screw 9 is sleeved on the limiting rod 23. The limiting rod 23 can improve the stability of the clamping plate 10 and prevent the end of the clamping plate 10 away from the bidirectional screw 9 from bending when clamping the sliding column 7, which would reduce the clamping effect.

[0042] The implementation principle of the paper rope feeding guide mechanism in this application embodiment is as follows: In use, the user first pulls the sliding column 7, causing the U-shaped frame 4 to move upwards, allowing the paper rope to pass between the first pressing roller 3 and the second pressing roller 5. Then, the user releases the sliding column 7, causing the U-shaped frame 4 to move downwards under the return of the spring 20, bringing the second pressing roller 5 closer to the first pressing roller 3 to press the paper rope. Then, by starting the drive motor 11, the bidirectional screw 9 rotates, causing the two clamping plates 10 to move closer to each other under the constraint of the first through groove 8, clamping and fixing the sliding column 7, so that the paper rope passes between the first pressing roller 3 and the second pressing roller 5. The paper rope is shaped and straightened. It passes between the first tension roller 13 and the second tension roller 16. By rotating the adjusting bolt 17, the sliding block 15 slides in the second through groove 14, which moves the second tension roller 16. This presses down on the paper rope and adjusts its tension, making it easier to transport the paper rope to the processing position. This method avoids the difficulty of controlling the pressing force of the first and second rotating rollers on the paper rope by manually rotating the screw. Excessive force may deform the rubber ring and damage the paper rope, reducing its applicability.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
