Description

Technical Field

[0001] The utility model relates to the technical field of paper tube processing equipment, in particular to a top pressing device. Background Art

[0002] With the widespread application of chemical fiber paper tubes in packaging and other fields, their production efficiency and product quality have become a focus of industry attention. As a key step in the production process of chemical fiber paper tubes, the cutting and feeding process plays an indispensable role in ensuring the dimensional accuracy, appearance quality, and overall production efficiency of the paper tubes.

[0003] Traditionally, in order to accurately groove chemical fiber paper tubes, a ram is usually used in the cutting and feeding process. The paper tube is pushed in for precise grooving, and then the ram is withdrawn from the paper tube to ensure that the paper tube is not easily dropped. However, this process requires frequent pushing and pulling operations. After long-term use, the surface where the ram contacts the chemical fiber paper tube is prone to wear due to long-term friction. This wear not only affects the positioning accuracy and stability of the ram, but also directly threatens the production quality of chemical fiber paper tubes.

[0004] To address the wear problem, manufacturers will first repair the worn surface of the plug by wrapping tape around it. However, the tape is easily worn and adheres to the chemical fiber paper tube after friction with the chemical fiber paper tube, making the pushing and pulling process more difficult. If the entire plug is replaced directly, it will not only be costly but also inconvenient to operate. Utility Model Content

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, a top pressing device includes a support frame 1, which is fixed on a workbench, a servo cylinder 2 is provided on the support frame 1, and a pushing portion is provided at the output end of the servo cylinder 2, which includes a boss 3, a limiting plate 4 is provided at one end of the boss 3, and at least three grooves 5 are evenly provided on the outer surface of the boss 3, and an extrusion portion is provided inside each groove 5, which includes a top block 6, a mounting groove 7 is provided on the lower surface of the top block 6, a compression spring 8 is provided at the bottom of the groove 5, the mounting groove 7 on the top block 6 is sleeved on the outside of the compression spring 8, a through waist hole 9 is provided on the top block 6, a pin hole is provided on the limiting plate 4 and the boss 3, and also includes a pin shaft 10 for passing through the pin hole and the waist hole 9, a threaded hole is provided on the outer surface of the limiting plate 4 and the pin hole, and the internal thread of the threaded hole is connected with a locking bolt 11.

[0020] The presence of the pin 10 will restrict the top block 6 in the groove 5 , and at the same time, due to the presence of the waist hole 9 , the top block 6 can move up and down in the groove 5 .

[0021] When the boss 3 is pushed into the chemical fiber paper tube by the servo cylinder 2, the inner wall of the chemical fiber paper tube will squeeze the top block 6 on the boss 3. When the top block 6 is squeezed, it will enter the inside of the groove 5. At the same time, the compression spring 8 will be compressed. The reaction force of the compression spring 8 will act on the chemical fiber paper tube through the top block 6. When one end of the chemical fiber paper tube contacts the limit plate 4, the chemical fiber paper tube cannot continue to move on the boss 3. After the servo cylinder 2 pulls the boss 3 out of the chemical fiber paper tube, under the action of the compression spring 8, the top block 6 is reset to facilitate the pressing of the next chemical fiber paper tube.

[0022] Furthermore, four mounting grooves 7 are provided, and the four mounting grooves 7 are evenly arranged on the lower surface of the top block 6. Four compression springs 8 are provided, and the four compression springs 8 are evenly arranged at the bottom of the groove 5. The positions of the compression springs 8 correspond one to one to the positions of the mounting grooves 7. When the top block 6 contacts the chemical fiber paper tube, multiple compression springs 8 can provide a more uniform and comprehensive buffering effect, jointly absorb the impact force, and enhance the buffering effect.

[0023] Furthermore, one end of the top block 6 away from the limiting plate 4 is configured as an arc-shaped surface, so that the chemical fiber paper tube can be more smoothly sleeved on the outer surface of the top block 6, facilitating the pushing and pulling operation.

[0024] Furthermore, the surface of the top block 6 that contacts the inner wall of the chemical fiber paper tube is configured as an arc-shaped surface, thereby increasing the contact area between the top block 6 and the inner wall of the chemical fiber paper tube and avoiding severe local friction.

[0025] Furthermore, the top block 6 is made of nylon plastic to further reduce the friction between it and the chemical fiber paper tube.

[0026] When the top block 6 is worn, the locking bolt 11 can be unscrewed and the pin 10 can be pulled out to complete the replacement of the top block 6, so there is no need to replace the entire pushing part, which reduces the replacement cost and makes replacement convenient. In addition, the provided compression spring 8 can reduce the wear between the chemical fiber paper tube and the top block 6, extend the service life of the top block 6, and have a good use effect.

[0027] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
