Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of self-adhesive label production equipment, and in particular to an automatic waste discharge device for sheet-type self-adhesive label production. Background Technology
[0002] In the production process of sheet-type self-adhesive labels, a large amount of waste is generated after the labels are cut and separated from the raw materials;
[0003] Traditional waste removal methods often have many problems. For example, relying on manual operation is not only inefficient and costly, but also prone to damaging labels during operation. Some existing automated waste removal equipment is not adaptable to label waste of different thicknesses and materials, making it difficult to complete the waste removal work accurately and efficiently. In addition, some equipment has a complex structure and high maintenance costs, which cannot meet the actual production needs.
[0004] Therefore, this utility model proposes an automatic waste discharge device for the production of sheet-type self-adhesive labels. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic waste discharge device for the production of sheet-type self-adhesive labels.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic waste discharge device for the production of sheet-type self-adhesive labels, comprising a roller assembly, the roller assembly consisting of a cylinder and cover plates disposed on both sides, and further comprising:
[0007] An adaptive component is formed by a rubber cylinder disposed inside the cylindrical body. The rubber cylinder has a semi-circular cavity, and there are four semi-circular cavities in total, which are arranged in a ring. A rectangular cavity is formed on the rubber cylinder between the four semi-circular cavities.
[0008] Furthermore, the diameter of the rubber tube is smaller than the diameter of the cylinder body, and the length of the rubber tube is adapted to the length of the cylinder body.
[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: because the diameter of the rubber tube is smaller than that of the cylinder body, it can form a movable space inside. When the waste material comes into contact with the roller and generates pressure, the rubber tube undergoes elastic deformation due to its semi-arc and rectangular cavity structure. This deformation allows it to adapt to the shape and pressure of different waste materials. At the same time, it avoids damage to the label through its own elastic buffer. The length-adaptive design ensures that it can play a role in the entire range of the cylinder body. When the entire roller assembly rotates to discharge waste, it can not only stably adhere the waste material, but also improve the applicability and reliability of waste discharge through the adaptive deformation of the rubber tube.
[0010] Furthermore, the cylinder is provided with four adhesive waste discharge components, which are arranged in a rectangular pattern.
[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the four rectangularly distributed adhesive waste removal components rotate with the cylinder. The adhesive seat can elastically extend and retract through the sliding limit rod and spring structure. When the waste comes into contact with the arc-shaped adhesive plate, the elastic buffer of the spring allows the adhesive plate to adaptively adhere to waste of different thicknesses, maintain stable adhesion force, and avoid adhesion failure caused by uneven waste thickness. The rectangular distribution layout allows the roller to effectively contact the waste in all directions during rotation. The adhesiveness of the adhesive plate continuously carries the waste away, achieving efficient waste removal in the entire circumference. The structure is simple and has strong self-adaptability.
[0012] Furthermore, the adhesive waste discharge assembly consists of an adhesive base and a sliding limiting rod that penetrates the cylinder. A spring is provided on the sliding limiting rod, and the two ends of the spring are respectively connected to the adhesive base and the cylinder.
[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: the adhesive seat slides within the cylinder via a sliding limit rod, and the two ends of the spring are connected to the adhesive seat and the cylinder respectively, forming an elastic buffer structure. When the waste material contacts the adhesive seat, the spring can automatically adjust the extension and contraction of the adhesive seat according to the pressure of the waste material, so that the adhesive seat can not only closely adhere to the surface of the waste material to enhance the adhesion, but also adapt to waste materials of different hardness and thickness through elastic deformation, avoiding damage to the label or the waste material falling off due to hard contact. The sliding limit rod ensures that the adhesive seat slides in a fixed direction, ensuring the stability and reliability of the waste discharge process and achieving efficient adaptive waste discharge.
[0014] Furthermore, an arc-shaped adhesive plate is provided at the end of the adhesive seat away from the roller assembly. The arc-shaped adhesive plate has an arc-shaped structure, and the curvature of the arc-shaped adhesive plate is adapted to the curvature of the adhesive seat.
[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the arc-shaped adhesive plate, relying on the arc structure adapted to the adhesive seat, can form a smooth curved contact area during the rotation of the roller. When the waste material comes into contact with the arc surface, the curved surface design can increase the contact area with the waste material and improve the adhesive adsorption effect. At the same time, the buffering characteristics of the arc structure can reduce the hard collision between the waste material and the adhesive plate, and prevent the waste material from tearing or falling off due to uneven force. Moreover, the adapted arc allows the adhesive plate to closely fit the roller rotation trajectory, ensuring that the waste material can be stably adhered at different angles, and enhancing the continuity and reliability of waste discharge.
[0016] Furthermore, a connecting shaft is provided at the end of the cover plate away from the cylinder.
[0017] The beneficial effects of adopting the above-mentioned further solution are: the connecting shaft at one end of the cover plate can be connected to the transmission mechanism of the production equipment, and the roller assembly can be stably installed on the equipment through the connecting shaft, so that it can rotate synchronously with the transmission mechanism. The setting of the connecting shaft not only provides reliable rotation support for the roller assembly, but also ensures the smooth rotation of the roller during the waste discharge process, so that the adhesive waste discharge component and the self-adaptive component can continuously and evenly contact the waste, ensuring that the waste discharge action is carried out continuously. At the same time, it simplifies the assembly process of the device with other equipment and improves the stability and practicality of the overall structure.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, the rubber cylinder inside the cylinder forms an elastic deformation space through four annularly distributed semi-circular cavities and rectangular cavities. When waste material squeezes the roller, the rubber cylinder can adaptively deform with the help of the cavity structure, closely conforming to the contour of the waste material, enhancing the contact stability during waste discharge. The cavity design gives the rubber cylinder buffer performance, which can not only avoid squeezing the label, but also continuously provide adsorption force through elastic reset. During the rotation of the roller, the deformation characteristics of the rubber cylinder can adapt to the pressure and shape of different waste materials, improving the environmental adaptability and reliability of the waste discharge device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic waste discharge device for the production of sheet-type self-adhesive labels, including a roller assembly 1, which consists of a cylinder 11 and cover plates 12 disposed on both sides, and further includes:
[0031] The adaptive component 3 consists of a rubber cylinder 31 disposed inside the cylinder 11. Four semi-circular cavities 32 are provided inside the rubber cylinder 31 and are arranged in a ring. A rectangular cavity 33 is provided on the rubber cylinder 31 between the four semi-circular cavities 32. Through the structure of the four ring-shaped semi-circular cavities 32 and the rectangular cavity 33, an elastic deformation space is formed by the rubber cylinder 31 inside the cylinder 11. When waste material squeezes the roller, the rubber cylinder 31 can adaptively deform using the cavity structure, closely conforming to the contour of the waste material, enhancing contact stability during waste discharge. The cavity design gives the rubber cylinder 31 buffering performance, preventing label compression and providing continuous adsorption force through elastic reset. This allows the roller to adapt to the pressure and shape of different waste materials during rotation by utilizing the deformation characteristics of the rubber cylinder 31, improving the environmental adaptability and reliability of the waste discharge device.
[0032] The diameter of the rubber cylinder 31 is smaller than that of the cylinder 11, and the length of the rubber cylinder 31 is adapted to the length of the cylinder 11. During operation, the rubber cylinder 31 can form a moving space inside the cylinder 11 because its diameter is smaller than that of the cylinder 11. When the waste material comes into contact with the roller and generates pressure, the rubber cylinder 31 undergoes elastic deformation due to its semi-arc and rectangular cavity 33 structure. This deformation allows it to adapt to the shape and pressure of different waste materials. At the same time, it avoids damage to the label through its own elastic buffer. The length-adaptive design ensures that it can play a role in the entire range of the cylinder 11. When the entire roller assembly 1 rotates to discharge waste, it can not only stably adhere the waste material, but also improve the applicability and reliability of waste discharge through the adaptive deformation of the rubber cylinder 31.
[0033] The cylinder 11 is equipped with four adhesive waste removal components 2, which are arranged in a rectangular pattern. During operation, the four rectangular adhesive waste removal components 2 rotate with the cylinder 11. The adhesive seat 21 can elastically extend and retract through the sliding limit rod 23 and the spring 22. When the waste material contacts the arc-shaped adhesive plate 24, the elastic buffer of the spring 22 allows the adhesive plate to adapt to the different thicknesses of the waste material, maintain a stable adhesion force, and avoid adhesion failure caused by uneven thickness of the waste material. The rectangular layout allows the roller to effectively contact the waste material in all directions during rotation. The adhesiveness of the adhesive plate continuously carries away the waste material, achieving efficient waste removal in the entire circumference. The structure is simple and has strong self-adaptability.
[0034] The adhesive waste removal component 2 consists of an adhesive base 21 and a sliding limiting rod 23 penetrating the cylinder 11. A spring 22 is installed on the sliding limiting rod 23, with both ends of the spring 22 connected to the adhesive base 21 and the cylinder 11, respectively. During operation, the adhesive base 21 slides within the cylinder 11 via the sliding limiting rod 23. The two ends of the spring 22 are connected to the adhesive base 21 and the cylinder 11, forming an elastic buffer structure. When waste comes into contact with the adhesive base 21, the spring 22 can automatically adjust the extension and contraction of the adhesive base 21 according to the waste pressure, so that the adhesive base 21 can not only tightly adhere to the surface of the waste to enhance adhesion, but also adapt to waste of different hardness and thickness through elastic deformation, avoiding hard contact that could damage the label or cause the waste to fall off. The sliding limiting rod 23 ensures that the adhesive base 21 slides in a fixed direction, guaranteeing the stability and reliability of the waste removal process and achieving efficient adaptive waste removal.
[0035] An arc-shaped adhesive plate 24 is provided at the end of the adhesive seat 21 away from the roller assembly 1. The arc-shaped adhesive plate 24 has an arc structure, and the curvature of the arc-shaped adhesive plate 24 is adapted to the curvature of the adhesive seat 21. During operation, the arc-shaped adhesive plate 24, relying on the arc structure adapted to the adhesive seat 21, can form a smooth curved contact area as the roller rotates. When the waste material contacts the arc surface, the curved surface design can increase the contact area with the waste material and improve the adhesive adsorption effect. At the same time, the buffering characteristics of the arc structure can reduce the hard collision between the waste material and the adhesive plate, and prevent the waste material from tearing or falling off due to uneven force. Moreover, the adapted curvature allows the adhesive plate to closely fit the roller rotation trajectory, ensuring that the waste material can be stably adhered at different angles, and enhancing the continuity and reliability of waste discharge.
[0036] A connecting shaft 121 is provided at one end of the cover plate 12 away from the cylinder 11. During operation, the connecting shaft 121 at one end of the cover plate 12 can be connected to the transmission mechanism of the production equipment. The roller assembly 1 is stably installed on the equipment through the connecting shaft 121, so that it can rotate synchronously with the transmission mechanism. The setting of the connecting shaft 121 not only provides reliable rotation support for the roller assembly 1, but also ensures the smooth rotation of the roller during the waste discharge process. This allows the adhesive waste discharge assembly 2 and the adaptive assembly 3 to continuously and evenly contact the waste material, ensuring that the waste discharge action is carried out continuously. At the same time, it simplifies the assembly process of the device with other equipment and improves the stability and practicality of the overall structure.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
