Film edge scraper structure of high-speed compound machine

Abstract

The utility model discloses a film edge scraper structure of a high-speed compound machine, which is characterized in that an arc R-angle scraper (with the radius of 4-7mm) is driven by a rotating shaft to swing to be in contact with a rubber roller so as to scrape a wound film edge in real time, and a standby pressing roller is arranged to adjust the fitting precision of the rubber roller and a compound roller, so that the compound quality problem caused by film edge accumulation is solved. The laminating machine has the characteristics of automatic cleaning, stable lamination and continuous production, and is suitable for a laminating composite production line.

Description

Technical Field

[0001] This utility model relates to the technical field of composite coating equipment, specifically to a high-speed composite machine film edge scraper structure. Background Technology

[0002] A coating machine creates composite materials with specific properties by uniformly applying a coating to the surface of flexible substrates such as paper, plastic film, non-woven fabric, and woven fabric, followed by cooling and setting. These properties include improved surface gloss, increased hardness and abrasion resistance, enhanced airtightness, water resistance, oil resistance, and moisture resistance.

[0003] When roll materials are laminated, film edges are left over during the molding process. These film edges are prone to getting tangled in the rubber rollers, leading to poor bonding of the roll material. Traditional manual cleaning methods are inefficient and affect production continuity. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a high-speed laminating machine film edge scraper structure that can automatically scrape off the film edge of the rubber roller, prevent entanglement, and maintain the flatness of the composite.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed laminating machine film edge scraper structure, comprising:

[0006] A frame on which a composite roller and a rubber roller are mounted, wherein the composite roller is driven by a motor and is in contact with the rubber roller;

[0007] A rotating shaft is mounted on the frame. A swing seat is mounted on the rotating shaft, and a scraper is fixed on the swing seat. The tip of the scraper has an arc-shaped R-angle. The length of the scraper matches the length of the rubber roller. A handwheel is provided at the end of the rotating shaft. By rotating the handwheel, the rotating shaft is rotated, thereby causing the R-angle of the scraper to swing and contact the peripheral wall of the rubber roller to scrape off the film edge.

[0008] The backup pressure roller slides on a slide block mounted on a linear guide rail and is driven by a hydraulic cylinder. During its movement, the backup pressure roller pushes the rubber roller to contact and tightly adhere to the composite roller.

[0009] The radius of the R-angle is 4mm-7mm.

[0010] The scraper is made of stainless steel.

[0011] The axis of the backup pressure roller is parallel to the axis of the rubber roller.

[0012] The beneficial effects of this utility model are:

[0013] 1. The scraper's radius (R-angle) design enables damage-free edge scraping, and the rotation speed adapts for cleaning;

[0014] 2. Adjust the pressure rollers to ensure the alignment accuracy of the composite rollers;

[0015] 3. Reduce downtime for maintenance and improve production efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] like Figure 1 — Figure 3 As shown, this embodiment discloses a film edge scraper structure for a high-speed laminating machine, comprising:

[0023] A frame 1 is provided with a composite roller 2 and a rubber roller 3, wherein the composite roller 2 is driven by a motor and is in contact with the rubber roller 3;

[0024] A rotating shaft 5 is mounted on the frame 1. A swing seat 6 is mounted on the rotating shaft 5. A scraper 7 is fixed on the swing seat 6. The tip of the scraper 7 is provided with an arc-shaped R angle 71. The length of the scraper 7 matches the length of the rubber roller 3. A handwheel 51 is provided at the end of the rotating shaft 5. By rotating the handwheel 51, the rotating shaft 5 is driven to rotate, thereby causing the R angle 71 of the scraper 7 to swing and contact the peripheral wall of the rubber roller 3 to scrape off the film edge.

[0025] The backup pressure roller 4 is mounted on a slide block on a linear guide rail and is driven by a hydraulic cylinder. During its movement, the backup pressure roller 4 pushes the rubber roller 3 into contact with the composite roller 2.

[0026] The radius of the R-angle 71 is 4mm-7mm.

[0027] The scraper 7 is made of stainless steel.

[0028] The axis of the backup pressure roller 4 is parallel to the axis of the rubber roller 3.

[0029] When it is necessary to remove the film edge, the composite roller 2 operates, and the composite roller 2 is driven to rotate in conjunction with the adhesive roller 3. The rotating handwheel 51 drives the scraper 7 to contact the adhesive roller 3, and the R angle 71 scrapes off the film edge. The standby pressure roller 4 presses the adhesive roller 3 with a hydraulic cylinder to prevent swaying, and drives it to be lifted and bonded with the composite roller 2, while ensuring that the scraper 7 is in flat contact with the adhesive roller 3.

[0030] The above technical solution can achieve the following technical effects:

[0031] 1. The scraper's radius (R-angle) design enables damage-free edge scraping, and the rotation speed adapts for cleaning;

[0032] 2. Adjust the pressure rollers to ensure the alignment accuracy of the composite rollers;

[0033] 3. Reduce downtime for maintenance and improve production efficiency.
