Abstract
Description
Technical Field
[0001] This utility model relates to the field of toilet paper processing, specifically a fixing device for toilet paper roll processing. Background Technology
[0002] The processing of toilet paper rolls involves several key steps. After the narrow strip of paper is wound onto the paper core by the rolling machine to form a semi-finished roll of paper with a set diameter, the semi-finished roll needs to be fixed and clamped to prevent it from shifting during subsequent processing and affecting the processing.
[0003] Existing paper roll fixing devices mostly use a combination of rollers and clamps for fixing. However, this fixing method cannot achieve fast fixing, is inefficient, and affects subsequent paper roll processing. Therefore, it is necessary to invent a fixing device that can quickly fix paper rolls to improve production efficiency. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a fixing device for toilet paper roll processing to solve the technical problem that toilet paper rolls cannot be fixed quickly.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for toilet paper roll processing, comprising a cylinder and a paper core, a slide rod fixedly connected to the output end of the cylinder, an installation cylinder sleeved on the slide rod, a first slide platform and a second slide platform slidably connected to the outer wall of the installation cylinder, a first clamping plate rotatably connected to the first slide platform, a first support platform fixedly connected to the end of the first clamping plate away from the first slide platform, a first support plate rotatably connected to the bottom end of the installation cylinder, a first support plate rotatably connected to the side wall of the first support plate away from the installation cylinder, a second support plate rotatably connected to the second slide platform, a second clamping plate rotatably connected to the side wall of the installation cylinder, a second support platform fixedly connected to the end of the second clamping plate away from the installation cylinder, and a second support plate rotatably connected to the side wall of the second clamping plate away from the second slide platform, both the first slide platform and the second slide platform being bolted to the slide rod, and a groove for the bolt to pass through being provided on the installation cylinder.
[0006] By adopting the above technical solution, the device drives the slide rod to move through the cylinder, and then the slide rod drives the first slide table and the second slide table to slide on the mounting cylinder, thereby realizing the rotation of the first clamping plate and the second clamping plate and fixing the paper core. The setting of the support platform increases the contact area with the paper core.
[0007] Furthermore, the bottom end of the slide rod and the bottom end of the first slide are in the same plane.
[0008] By adopting the above technical solution, it is ensured that the slide bar has sufficient travel while facilitating the fixation of the first slide table.
[0009] Furthermore, the top end of the mounting cylinder is fixedly connected to the bottom end of the cylinder, and the length of the mounting cylinder is greater than that of the slide rod.
[0010] By adopting the above technical solution, the movement of the mounting cylinder is restricted, ensuring that the slide rod has sufficient sliding stroke in the mounting cylinder, and guaranteeing that the slide rod mounting cylinder can slide relative to each other.
[0011] Furthermore, when the bottom end of the first slide rod is on the same plane as the bottom end of the mounting cylinder, both the first clamping plate and the second clamping plate rotate to their maximum angle.
[0012] By adopting the above technical solution, a clear positional standard is provided for the operation of the device, limiting the excessive rotation of the first and second clamping plates and preventing damage to the paper core.
[0013] Furthermore, the second slide is positioned above the connection point between the second support plate and the mounting cylinder.
[0014] By adopting the above technical solution, the direction of force exerted by the second support plate on the second clamping plate on the second slide is ensured, thus ensuring the normal operation of the work.
[0015] Furthermore, a first clamping plate is evenly arranged on the side wall of the first slide, and a plurality of second support plates are evenly arranged on the side wall of the second slide.
[0016] By adopting the above technical solution, a uniform force can be provided when fixing the paper core, preventing damage to the paper core from a single direction and better fixing the paper core.
[0017] Furthermore, the ends of the first and second support platforms facing the paper core are configured as arc-shaped surfaces.
[0018] By adopting the above technical solution, it can better fit with the inner wall of the paper core, making the fixation more uniform.
[0019] In summary, the present invention has the following main advantages: This utility model achieves the rotation of the first clamping plate and the second clamping plate through the cooperation of the sliding rod mounting cylinder, the first sliding table, the second sliding table, the first support plate and the second support plate, thereby realizing the fixation of the paper core by the first support plate and the second support plate, which can achieve quick fixation and facilitate subsequent processing.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] In this example: A fixing device for toilet paper roll processing, such as Figure 1-4As shown, the device includes a cylinder 1 and a paper core 12. A slide rod 2 is fixedly connected to the output end of the cylinder 1. The slide rod 2 and the output end of the cylinder 1 have the same diameter. A mounting cylinder 3 is fitted over the slide rod 2, with the inner wall of the mounting cylinder 3 fitting against the outer wall of the slide rod 2. A first slide platform 4 and a second slide platform 5 are slidably connected to the outer wall of the mounting cylinder 3. The first slide platform 4 and the second slide platform 5 are cylindrical structures, fitted onto the outer wall of the mounting cylinder 3, and the inner walls of the first slide platform 4 and the second slide platform 5 are fitted against the outer wall of the mounting cylinder 3. A rotatable connection is made on the first slide platform 4. The device includes a first clamping plate 6. A plate-shaped protrusion is fixed to the outer wall of the first slide 4 to facilitate the rotation and installation of the first clamping plate 6. A first support platform 8 is fixedly connected to the end of the first clamping plate 6 away from the first slide 4. The first support platform 8, as a component that directly contacts the paper core 12, increases the contact area between the first clamping plate 6 and the paper core 12. A first support plate 10 is rotatably connected to the bottom end of the mounting cylinder 3. A protrusion is fixed to the bottom end of the mounting cylinder 3 to facilitate the installation of the first support plate 10. The end of the first support plate 10 away from the mounting cylinder 3 is rotatably connected to... On the side wall of the first support plate 10, the angle of the first support plate 10 can be adjusted synchronously with the rotation of the first clamping plate 6. A second support plate 11 is rotatably connected to the side wall of the second slide table 5. A protrusion is fixed on the side wall of the second slide table 5 to facilitate the connection of the second support plate 11. A second clamping plate 7 is rotatably connected to the side wall of the mounting cylinder 3. A protrusion is fixed on the mounting cylinder 3 to facilitate the installation of the second clamping plate 7. The second clamping plate 7 rotates vertically. A second support platform 9 is fixedly connected to the end of the second clamping plate 7 away from the mounting cylinder 3. The support platform 9, as a component that directly contacts the paper core 12, can increase the contact area between the second clamping plate 7 and the paper core 12. The end of the second support plate 11 away from the second slide 5 is rotatably connected to the side wall of the second clamping plate 7, so that the first support plate 10 and the second clamping plate 7 can rotate together. The first slide 4 and the second slide 5 are both connected to the slide rod 2 by bolts 13. The bolt 13 connection is convenient for disassembly and assembly. The mounting cylinder 3 is provided with a sliding groove 14 for the bolt 13 to pass through, providing sliding space for the first slide 4 and the second slide 5. See Figure 4 When the cylinder 1 retracts, the bottom end of the slide rod 2 and the bottom end of the first slide table 4 are in the same plane, ensuring that the slide rod 2 has sufficient stroke while facilitating the fixation of the first slide table 4. See Figure 1 Figure 4 The top end of the mounting cylinder 3 is fixedly connected to the bottom end of the cylinder 1. The length of the mounting cylinder 3 is greater than that of the sliding rod 2, ensuring that the sliding rod 2 can slide inside the mounting cylinder 3 without extending out of the mounting cylinder 3 and affecting the subsequent processing of the paper core 12. See Figure 1 , Figure 4When the bottom end of the slide bar 2 is on the same plane as the bottom end of the mounting cylinder 3, the first clamping plate 6 and the second clamping plate 7 are both rotated to the maximum angle, thus determining the maximum rotational stroke of the first clamping plate 6 and the second clamping plate 7, and thus determining the maximum inner diameter of the paper core 12 that can be fixed. See Figure 1 , Figure 4 The second slide 5 is positioned above the connection point between the second support plate 11 and the mounting cylinder 3, ensuring the direction of force exerted by the second support plate 11 on the second slide 5 on the second clamping plate 7, and ensuring normal operation. See Figure 1 Multiple first clamping plates 6 are evenly arranged on the side wall of the first slide table 4, and multiple second support plates 11 are evenly arranged on the side wall of the second slide table 5. They can provide all-round support and fixation for the paper roll from the circumferential direction, so as to avoid uneven stress on the paper core 12. See Figure 1 , Figure 2 , Figure 3 The ends of the first support platform 8 and the second support platform 9 facing the paper core 12 are set as arc-shaped surfaces. The arc-shaped surfaces can perfectly fit the cylindrical curved surface of the paper roll, further increasing the contact area and ensuring the stability of the fixation. The implementation principle of this embodiment is as follows: First, the output end of the cylinder 1 extends out, and the first slide 4 slides down along the mounting cylinder 3, causing the first clamping plate 6 to also move down. Under the action of the first support plate 10, the first clamping plate 6 rotates outward. The first clamping plate 6 drives the rotation of the first support plate 10, reducing the angle between the first support plate 10 and the first clamping plate 6. Under the action of the first clamping plate 6, the first support platform 8 contacts the inner wall of the paper core 12. Under the action of multiple supports, the paper core 12 is fixed. The second slide 5 moves down, causing the second support plate 11 to also move down. Then, the angle between the second support plate 11 and the second clamping plate 7 decreases, causing the second clamping plate 7 to also rotate outward. The second clamping plate 7 drives the second support platform 9 to fit against the inner wall of the paper core 12. Under the action of multiple second supports 9, the paper core 12 is fixed. At the same time, the interaction between the second support platform 9 and the first support platform 8 provides better fixation for the paper core 12, preventing the paper core 12 from deforming.
