Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of packaging material manufacturing, and particularly relates to a glue dirt removing device of a composite roller. BACKGROUND

[0002] In the field of soft packaging material manufacturing, during the compounding process of a compounding machine, the transfer film is compounded with the original white cardboard after being glued, and glue overflow is generated at the edges of the product under certain pressure during compounding. Glue dirt is accumulated and formed at the position close to the edges of the transfer film on the composite roller. Under the mutual extrusion of the glue dirt and the just compounded product, the glue amount of the un-solidified product edge is abnormal, which causes poor adhesion of the aluminum layer of the product after the product is peeled off, and the aluminum layer is prone to falling off after frequent rubbing in the subsequent printing process, resulting in quality problems and seriously affecting the normal production of the product.

[0003] In order to remove the glue dirt accumulated and formed on the composite roller, a special glue dirt removing device is generally used for scraping. The glue dirt removing device of the prior art is usually provided with a blade structure on a frame body arranged along the length direction of the composite roller, and the glue dirt on both sides of the transfer film on the composite roller is removed, and the blade needs to be replaced according to the degree of wear. Although the glue dirt can be scraped to a certain extent, the blade needs to be replaced as a whole when it is replaced, which is not very convenient to operate in a small space, and the angle adjustment freedom of the blade and the composite roller is small, which may affect the removal effect. CONTENT OF THE UTILITY MODEL

[0004] The technical problem to be solved by the application is to provide a glue dirt removing device of a composite roller, and the problem of inconvenient replacement of the blade in the prior art is solved.

[0005] The application provides a glue dirt removing device of a composite roller, which comprises:

Detailed Implementation

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] like Figure 1 and Figure 2 As shown, the present application provides a device for removing adhesive residue from a composite roller, comprising: a support structure 10 and at least two scraping mechanisms 20; wherein each scraping mechanism 20 includes a connecting seat 210, a support arm 220 disposed on the connecting seat 210, and a scraper assembly 230 detachably disposed at one end of the support arm 220, and at least two scraper assemblies 230 are respectively used to remove adhesive residue from both sides of the transfer film.

[0023] Compared with the prior art, the adhesive residue removal device for the composite roller provided in this application removes adhesive residue from the positions near the two sides of the transfer film on the composite roller after assembly. When the scraper assembly 230 is worn to a certain extent, it is only necessary to disassemble the corresponding scraper assembly 230 and replace it with a new scraper assembly 230. The size of a single scraper assembly 230 is smaller and it is relatively easier to replace, which has high convenience.

[0024] In one possible implementation, the support structure 10 includes a support beam 110, at least two mounting seats 120 for fixing the support beam 110, and a connecting seat 210 disposed on the support beam 110. The connecting seat 210 is sleeved on the support beam 110 and can be rotated and adjusted. A knob bolt 211 is screwed onto the connecting seat 210 for fastening. Specifically, the support beam 110 is arranged parallel to the composite roller that needs to be cleaned of adhesive residue, and its length is slightly larger. By loosening the knob bolt 211, the connecting seat 210 can be rotated according to the actual situation, causing the support arm 220 to deflect at a certain angle. Then, the knob bolt 211 is tightened to fix the connecting seat 210, thereby adjusting the distance between the scraper assembly 230 and the surface of the composite roller within a certain range, which is beneficial for more thorough removal of adhesive residue. This effectively avoids the potential problems of poor aluminum layer adhesion and aluminum powder shedding in various products after composite peeling due to incomplete removal of adhesive residue.

[0025] In one possible implementation, the support beam 110 includes a cylindrical rod 111, and the connecting seat 210 has a first circular hole 212 for the cylindrical rod 111 to pass through. A knob bolt 211 abuts against the cylindrical rod 111 to secure the connecting seat 210. Specifically, the side of the connecting seat 210 has a threaded hole that matches the knob bolt 211. The operator holds the knob bolt 211 with one hand and the support arm with the other to deflect it. When the surface distance between the scraper assembly 230 and the composite roller is appropriate, the knob bolt 211 is tightened.

[0026] In some embodiments, the connecting seat 210 and the supporting beam 110 can also be fixedly connected by bolts, or the connecting seat 210 and the supporting beam 110 can be fixed by welding.

[0027] In one possible implementation, the supporting beam 110 further includes two polygonal prisms 112 respectively disposed at both ends of the cylindrical rod 111. The mounting base 120 has polygonal holes 121 that match the polygonal prisms 112, and the mounting base 120 is screwed with a first fastening bolt 122 for fixing the polygonal prisms 112. Specifically, the polygonal prisms 112 can be triangular, quadrangular, or hexagonal prisms. The polygonal prisms 112 and the cylindrical rod 111 are integrally formed and can be made of steel, formed by casting or machining. During assembly, the two polygonal prisms 112 at both ends of the cylindrical rod 111 are inserted into the polygonal holes 121 of the two mounting bases 120 respectively, and then the two mounting bases 120 are fixed on corresponding bases, which can be frames for mounting composite rollers, thereby fixing the cylindrical rod 111.

[0028] In one possible implementation, one edge of the polygonal prism 112 has a positioning hole 1121, and a fastening bolt is screwed to the top of the mounting base 120 and engages with the positioning hole 1121. The engagement of the fastening bolt with the positioning hole 1121 can improve the stability of the support beam 110 and allow the support beam 110 to be pre-assembled with the two mounting bases 120.

[0029] In one possible implementation, the connecting seat 210 has a positioning screw hole 213, and the support arm 220 has an elongated hole 221. A second fastening bolt 222 is disposed in the elongated hole 221, and the second fastening bolt 222 is screwed into the positioning screw hole 213 to fix the support arm 220. Specifically, loosening the second fastening bolt 222 allows the support arm 220 to move along the elongated hole 221 to adjust the distance between the scraper assembly 230 and the composite roller, and then tightening the second fastening bolt 222 fixes the support arm 220.

[0030] In one possible implementation, the scraper assembly 230 includes a blade holder 231 sleeved on one end of the support arm 220 and rotatably adjustable, and a blade 232 disposed on the blade holder 231. A third fastening bolt is screwed to the side of the blade holder 231 for abutting against the support arm 220 to fix the blade holder 231. Specifically, after adjusting the distance between the scraper assembly 230 and the composite roller, the scraper assembly 230 can be rotated and adjusted by loosening the third fastening bolt, so that the blade 232 is parallel to or at a certain angle to the axis of the composite roller. When the blade 232 has a certain angle with the axis of the composite roller, the blade 232 used is a blade with an arc-shaped cutting edge, ensuring full contact with the surface of the composite roller (distance close to zero), making it easier to remove adhesive residue, and pushing the removed adhesive residue away from the transfer film like a plow, preventing the detached adhesive from sticking to the transfer film.

[0031] In one possible implementation, a circular shaft 223 is provided at one end of the support arm 220, and the blade holder 231 has a second circular hole 2311 that matches the circular shaft 223 for inserting the circular shaft 223. A third fastening bolt abuts against the side of the circular shaft 223 to fasten the blade holder 231. Specifically, the support arm 220 and the circular shaft 223 are integrally formed and can be made of steel, which can be formed by casting or machining. Loosening the third fastening bolt allows the blade holder 231 to rotate around the axis of the circular shaft 223, thereby adjusting the angle of the blade 232. Tightening the third fastening bolt secures the scraper assembly 230.

[0032] In one possible implementation, the blade holder 231 and the blade 232 are fastened together by at least two bolts. This facilitates the replacement of the blade 232 without replacing the entire scraper assembly 230, and ensures the strength of the connection between the blade holder 231 and the blade 232.

[0033] In one possible implementation, the mounting base 120 has at least two mounting holes 123 for securing the mounting base 120 to the corresponding base by at least two bolts. This facilitates the installation and removal of the support structure 10.
