Description

Technical Field

[0001] This utility model belongs to the field of winding machine technology, and in particular relates to a wrinkle-resistant barrel-shaped self-adhesive high-efficiency winding machine. Background Technology

[0002] Self-adhesive labels (also known as pressure-sensitive labels) are ubiquitous in daily life, widely used in food and beverage packaging, logistics and transportation, daily chemical products, pharmaceuticals, electronics, retail, and many other fields. Their basic structure typically consists of three layers: the face stock (printing substrate), the pressure-sensitive adhesive (adhesive layer), and the backing paper (release layer, protective adhesive layer). In the entire self-adhesive label manufacturing process, the winding device plays a crucial role, serving as a key link connecting coating, printing, and slitting processes with the final product.

[0003] However, traditional winding machines require complete disassembly or complex operations to remove the roll of material after winding the barrel-shaped self-adhesive labels, resulting in low efficiency and potential material damage. Furthermore, the high-speed rotation of the disc during winding causes traditional bearings or fixed supports to generate significant frictional resistance, radial runout, or positional misalignment, leading to uneven winding and even wrinkles. To address these issues, we have developed a wrinkle-resistant, high-efficiency barrel-shaped self-adhesive label winding machine. Utility Model Content

[0004] The purpose of this invention is to provide a wrinkle-resistant, barrel-shaped, high-efficiency self-adhesive roll rewinding machine. By using a combination of a diagonal plate and a cylinder, the rewinding roller is controlled to rotate out between two sets of discs, thereby removing the rewound self-adhesive roll. At the same time, the ball block is positioned in the ball opening to ensure stable rotation of the discs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a wrinkle-resistant, barrel-shaped, high-efficiency self-adhesive rewinding machine, including a base plate; a rewinding roller is provided on the upper end face of the base plate, and discs are provided at both ends of the rewinding roller. A collar is fitted on the middle of the surface of the rewinding roller, and diagonal strips are fixed on the surface of the collar. A positioning plate is provided below each set of discs and bolted to the upper end face of the base plate. The lower part of the disc is located at the concave position on the upper surface of the positioning plate. A ball opening is opened on the concave surface of the upper surface of the positioning plate, and a ball block is provided inside the ball opening. An abutment frame is provided on the lower surface of the collar and bolted to the upper end face of the base plate. A cylinder is bolted to the upper end face of the base plate and located inside the abutment frame. The piston ends on both sides of the cylinder are bolted to the corresponding positioning plates. A motor is connected to the end face of the disc located to the right of the rewinding roller away from the rewinding roller, and the motor is mounted on the adjacent positioning plate.

[0007] The present invention is further configured such that a cross opening is provided at the middle position of both ends of the winding roller, and a cross post inserted into the cross opening is fixed on the end face of the disc.

[0008] The present invention is further configured such that sliding openings are provided on the upper surface of the bottom plate located on the left and right sides of the cylinder, and sliding blocks disposed in the sliding openings are fixed on the lower surface of the positioning plate.

[0009] The present invention is further configured such that an annular groove is provided at the middle position of the surface of the take-up roller, and an annular block is fixed at the middle of the inner wall of the collar, and the annular block is sleeved on the take-up roller located at the annular groove position.

[0010] The present invention is further configured such that a fulcrum shaft is fixed to the curved part of the diagonal strip on the upper end face of the base plate, the curved part of the diagonal strip is sleeved on the shaft of the fulcrum shaft through the through-hole, and a handle is fixed to the other end face of the diagonal strip away from the take-up roller.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model controls the position of the take-up roller between two sets of discs by using diagonal strips. Therefore, after the take-up roller rotates to the position above the two sets of discs, both ends of the take-up roller are exposed, and the self-adhesive rolls in drums can be directly pulled out on the take-up roller, which facilitates the quick removal of the self-adhesive rolls after they have been wound up.

[0013] 2. The lower part of the disc of this utility model is located at the upper recess of the positioning plate, so that the surface of the disc is in contact with the ball block on the inner wall of the recess on the positioning plate. After the disc rotates, it will drive the ball block to rotate in the ball opening, thereby reducing the friction of the disc during rotation and ensuring the stability of the disc position during rotation.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model is a high-efficiency anti-wrinkle barrel-shaped self-adhesive roll rewinding machine. By using the cooperation of the diagonal plate and the cylinder 4, the rewinding roller 2 is controlled to rotate out between the two sets of discs 3, so as to remove the rewinding self-adhesive roll. At the same time, the ball block 503 is in the ball mouth 501 to ensure the stable rotation of the disc 3.

[0025] Specifically, a base plate 1 is provided; a take-up roller 2 is provided on the upper end face of the base plate 1, and a disc 3 is provided at both ends of the take-up roller 2. A collar 201 is sleeved on the middle of the surface of the take-up roller 2, and a diagonal strip 205 is fixed on the surface of the collar 201. A positioning plate 5 is provided below each set of discs 3 and is bolted to the upper end face of the base plate 1. The lower part of the disc 3 is located in the concave position on the upper surface of the positioning plate 5. A ball opening 501 is opened on the concave surface of the upper surface of the positioning plate 5. A ball block 503 is provided inside the ball opening 501. An abutment frame 6 is provided on the lower surface of the collar 201 and is bolted to the upper end face of the base plate 1. A cylinder 4 is bolted to the upper end face of the base plate 1 and is located inside the abutment frame 6. The piston ends on both sides of the cylinder 4 are bolted to the corresponding positioning plates 5. A motor 7 is connected to the end face of the disc 3 located to the right of the take-up roller 2 away from the take-up roller 2, and the motor 7 is mounted on the adjacent positioning plate 5.

[0026] The operation process of this embodiment is as follows: Using the above-described structure, the non-adhesive surface of the self-adhesive is attached to the surface of the take-up roller 2 on one side of the collar 201. The motor 7 is then controlled to operate, causing the disc 3 to rotate. This, in turn, controls the take-up roller 2 and another set of discs 3 to rotate synchronously. The take-up roller 2 then winds up the self-adhesive attached to its surface. When the winding is complete and the self-adhesive, wound into a drum, needs to be removed from the take-up roller 2, the cylinder 4 is controlled to operate, pushing the two sets of discs 3 away from the take-up roller 2, thus disengaging the discs 3 from the take-up roller 2. The diagonal strip 205 controls the take-up roller 2's movement between the two sets of discs 3. The take-up roller 2 rotates to a position above the two sets of discs 3, exposing both ends of the take-up roller 2. This allows the packaged adhesive tape rolls to be directly pulled out from the take-up roller 2, facilitating quick removal of the rolled adhesive tape rolls. Simultaneously, when the motor 7 controls the rotation of the two sets of discs 3, the lower part of the disc 3 is located in the upper recess of the positioning plate 5, causing the surface of the disc 3 to contact the ball block 503 on the inner wall of the upper recess of the positioning plate 5. As a result, after the disc 3 rotates, it will drive the ball block 503 to rotate in the ball opening 501, thereby reducing the friction experienced by the disc 3 during rotation and ensuring the stability of the disc 3's position during rotation.

[0027] Example 2

[0028] Please see Figures 1 to 5 Based on Example 1, the use of the cross column 301 and the cross mouth 203 ensures that the winding roller 2 and the disc 3 can rotate synchronously.

[0029] Specifically, a cross opening 203 is provided at the middle of both ends of the winding roller 2, a cross post 301 inserted into the cross opening 203 is fixed on the end face of the disc 3, a sliding opening 102 is provided on the upper end face of the base plate 1 located to the left and right of the cylinder 4, and a sliding block 502 provided in the sliding opening 102 is fixed on the lower end face of the positioning plate 5.

[0030] The operation process of this embodiment is as follows: When the cross post 301 on the end face of the disc 3 is inserted into the cross opening 203 through the above structure, the disc 3 is assembled with the take-up roller 2. Therefore, after one set of discs 3 is driven to rotate, it will synchronously drive the take-up roller 2 and the other set of discs 3 to rotate, so that the self-adhesive can be wound up. At the same time, when the cylinder 4 controls the two sets of positioning plates 5 to move along the upper end face of the base plate 1, the positioning plate 5 will move in the sliding opening 102 through the sliding block 502. The sliding opening 102 limits the sliding block 502 to ensure the stable movement of the positioning plate 5.

[0031] Example 3

[0032] Please see Figure 3Based on Example 1, the take-up roller 2 is tilted up by the combined use of the fulcrum shaft, collar 201 and take-up roller 2.

[0033] Specifically, an annular groove 204 is provided in the middle of the surface of the take-up roller 2, and an annular block 202 is fixed in the middle of the inner wall of the collar 201. The annular block 202 is sleeved on the take-up roller 2 located in the annular groove 204. A fulcrum shaft bracket 101 is fixed to the bent part of the diagonal strip 205 on the upper end face of the base plate 1. The bent part of the diagonal strip 205 is sleeved on the shaft of the fulcrum shaft bracket 101 through the through shaft hole 207. A handle 206 is fixed to the other end face of the diagonal strip 205 away from the take-up roller 2.

[0034] The operation process of this embodiment is as follows: When it is necessary to control the take-up roller 2 to rotate out of the position between the two sets of discs 3, the lever 206 can be operated to move downward. The lever 206 will control the diagonal bar 205 to lift the take-up roller 2 with the fulcrum shaft 101 as the fulcrum, so that the take-up roller 2 can be directly rotated out of the position between the two sets of discs 3. At the same time, when the take-up roller 2 rotates, the annular groove 204 on the surface of the take-up roller 2 will rotate along the position of the annular block 202. The annular block 202 limits the annular groove 204 to ensure the stability of the rotation of the take-up roller 2. At the same time, through the cooperation of the annular block 202 and the take-up roller 2, the take-up roller 2 will not drive the annular block 202 to rotate when it rotates.
