Description

Technical Field

[0001] This utility model relates to the field of film production technology, and in particular to a device for cleaning adhesive residue from the edge of a coating roller. Background Technology

[0002] In the film production process, some types of films require solvent-free lamination on a coating machine. However, during low-speed operation, solvent-free lamination can lead to problems due to the transfer tube (also known as the coating roller, which has...) Figure 1 The working part 100, working part end face 200, transition part 300 and working part outer edge 400 shown (where the working part outer edge is also the working part end face outer edge) work part cooperates with the coating roller surface, the adhesive will be transferred to the edge of the working part of the coating roller and accumulate over time; if it is cleaned for a long time, the adhesive will solidify and affect the subsequent adhesive application width, that is, affect the adhesive application operation at the edge of the film, and increase the loss of film edge material.

[0003] The current practice is that after working for a certain period of time, the machine needs to be stopped and the coating rollers disassembled to clean the adhesive residue from the edges of the coating rollers' working section. This practice not only affects production but also requires manual labor.

[0004] To address this, we designed a device for cleaning residual adhesive on the edge of a coated roller. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a device for cleaning adhesive residue on the edge of a coated roller.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A device for cleaning adhesive residue from the edge of a coating roller includes a mounting plate. An extension rod is provided in the middle of one side of the mounting plate, and a scraper is provided at the end of the extension rod away from the mounting plate. One side of the scraper is an inclined section, and the distance from the outer side of the inclined section to the central axis of the coating roller is greater than the distance from the inner side of the inclined section to the central axis of the coating roller. The outer side of the inclined section is correspondingly and intersecting with the outer edge of the working part of the coating roller to facilitate scraping off the adhesive from the outer edge of the working part of the coating roller. The other side of the scraper is an upward-curved section, such that the inner side of the upward-curved section and the inner side of the inclined section form an adhesive flow groove.

[0008] Preferably, the outer side of the inclined section is parallel to the end face of the working part of the coating roller.

[0009] Preferably, the back of the scraper is provided with a set of support wheels.

[0010] Preferably, the support wheel assembly includes a wheel bracket, the top of which is attached to the back of the scraper to increase the scraper strength, and the bottom of the wheel bracket is provided with a support wheel that can be rolled onto the adhesive roller.

[0011] Preferably, the extension rod is a rod with telescopic function.

[0012] Preferably, the extension rod includes a first rod, one end of which is disposed on the mounting plate, and the other end is threaded with an adjusting nut. A magnetic slider is slidably connected to the first rod body, and a second rod for mounting a scraper is provided on one side of the magnetic slider.

[0013] Preferably, the outer end of the second rod is sealed at the lower port of the glue flow channel.

[0014] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0015] 1. It can scrape off the glue from the outer edge of the working section of the coating roller through the inclined section, and make the scraped glue flow down along the glue flow groove, so as to prevent the glue from accumulating in the scraper working area and affecting the glue cleaning operation. It solves the technical problem caused by the need to stop the machine for manual cleaning in the existing technology.

[0016] 2. The support wheel assembly not only effectively supports the scraper and prevents it from deforming, but also improves the stability of the scraper during operation by enabling the support wheel to roll in conjunction with the transition part.

[0017] 3. The specific structure of the extension rod allows for adjusting the travel of the magnetic slider by rotating the adjusting nut, thereby adjusting the length of the extension rod after extension; it also allows the installation plate to be attracted by the magnetic slider, keeping the extension rod in a stable retracted state, and the adjusting nut to be attracted by the magnetic slider, keeping the extension rod in a stable extended state.

Detailed Implementation

[0023] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0024] Example 1, in conjunction with Appendix Figure 1-4 A device for cleaning residual adhesive on the edge of a coating roller includes a mounting plate 1. An extension rod 2 is provided in the middle of one side of the mounting plate 1. A scraper 3 is provided at one end of the extension rod 2 away from the mounting plate 1. One side of the scraper 3 is an inclined section 31. The distance from the outer side of the inclined section 31 to the center axis of the coating roller is greater than the distance from the inner side of the inclined section 31 to the center axis of the coating roller. The outer side of the inclined section 31 is correspondingly and crosses the outer edge 400 of the working part of the coating roller to facilitate scraping off the adhesive on the outer edge of the working part of the coating roller.

[0025] As required, since the working end face 200 is not a working surface, the manufacturing tolerance is relatively large. In order to prevent the scraper 3 from contacting the working end face 200 and causing the scraper 3 to vibrate significantly, the outer side of the inclined section 31 does not contact the outer edge 400 of the working part of the rubber coating roller. Preferably, the distance between the outer side of the inclined section 31 and the outer edge 400 of the working part of the rubber coating roller is 1~3mm.

[0026] The other side of the scraper blade 3 is an upward-curving section 32, which forms a glue flow groove 33 with the inner side of the upward-curving section 32 and the inner side of the inclined section 31. That is, the glue scraped off by the scraper blade 3 from the edge of the coating roller can flow downward along the glue flow groove 33, preventing the glue from accumulating in the working area of ​​the scraper blade 3 and affecting the cleaning operation. In other words, the cross-section of the scraper blade 3 is approximately V-shaped; the bottom of this V-shape can also be flat or curved.

[0027] To prevent the adhesive from flowing onto the ground, the lower port of the adhesive flow channel 33 is sealed.

[0028] When in use, mounting plate 1 is installed on the frame of the glue applicator.

[0029] Example 2, in conjunction with Appendix Figure 4A device for cleaning residual adhesive on the edge of a coating roller, based on Embodiment 1, wherein, in order to prevent a large amount of adhesive from flowing to the end face 200 of the working section of the coating roller, the outer side of the inclined section 31 is parallel to the end face of the working section of the coating roller.

[0030] Example 3, in conjunction with Appendix Figure 2-3 A device for cleaning adhesive residue on the edge of a coated roller, based on embodiment one or two, provides a support wheel set 4 on the back of the scraper 3 to prevent the upper end of the scraper 3 from contacting the transition part 300, which could cause the scraper 3 to vibrate or be damaged; that is, the scraper 3 is supported by the support wheel set 4 to ensure that the scraper 3 will not come into contact with the transition part 300 in the rotating state due to the upper end shifting downward when scraping the adhesive.

[0031] Furthermore, the support wheel assembly 4 includes a wheel bracket 41, the top of which is attached to the back of the scraper 3. In other words, the top of the wheel bracket 41 is designed according to the width direction of the scraper 3, which can effectively support the scraper 3 and prevent it from deforming. The bottom of the wheel bracket 41 is provided with a support wheel 42 that can roll onto the adhesive roller; that is, by enabling the support wheel 42 to roll in cooperation with the transition part 300, the stability of the scraper 3 during operation can be improved.

[0032] Example 4, in conjunction with Appendix Figure 2 A device for cleaning adhesive residue on the edge of a coated roller, based on any one of the embodiments 1 to 3, wherein in order to prevent the device from affecting the disassembly and assembly of the coated roller, the extension rod 2 is a rod with telescopic function; that is, by shortening the length of the extension rod 2, the scraper 3 can be moved away from the working part 100.

[0033] To eliminate situations where the scraper 3 is too short from the mounting plate 1 due to manufacturing tolerances, resulting in a large distance between the scraper 3 and the end face 200 of the working part, or too long, causing the scraper 3 to abut against the outer edge 400 of the working part or even making it impossible to install, the extension rod 2 includes a first rod 21. One end of the first rod 21 is located on the mounting plate 1, and the other end is threaded with an adjusting nut 22. The first rod 21 is slidably connected to a magnetic slider 23, and a second rod 24 for installing the scraper 3 is provided on one side of the magnetic slider 23. That is, by rotating the adjusting nut 22, the travel of the magnetic slider 23 can be adjusted, thereby realizing the function of adjusting the length of the extension rod 2 after extension.

[0034] Specifically, the magnetic slider 23 can attract the mounting plate 1, so that the extension rod 2 is in a stable retracted state; the magnetic slider 23 can attract the adjusting nut 22, so that the extension rod 2 is in a stable extended state.

[0035] As needed, the first rod 21 is a cylindrical rod, and the magnetic slider 23 can rotate on the body of the first rod 21.

[0036] As needed, the outer end of the second rod 24 is sealed at the lower port of the glue flow channel 33, that is, the sealing operation of the lower port of the glue flow channel 33 is achieved through the outer end of the second rod 24.

[0037] In this example, the second rod 24 can be made of angle iron.

[0038] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
