Description

Technical Field

[0001] The utility model belongs to the technical field of laminating machines and relates to an anti-jamming structure of a laminating machine. Background Art

[0002] The laminating process involves bonding the encapsulated item to a polyester film coated with hot-melt adhesive through a laminating machine. Because the process is performed under pressure and high temperature, and because high-quality polyester film and transparent hot-melt adhesive are used, the encapsulated item is not only protected from damage at room temperature but also visually enhanced. However, during the laminating process, the film may warp due to the high temperature and become entangled in the laminating machine's rollers, causing it to become stuck and scrapped.

[0003] The patent with authorization announcement number CN213622547U discloses a laminating machine for preventing film jamming, including at least a pair of first roller and second roller squeezing each other, the two ends of the first roller and the second roller are fixed to the frame, and the film to be laminarized passes through the middle of the hot first roller and the second roller to realize hot melt lamination; annular narrow grooves are provided on the roller bodies of the first roller and the second roller; an anti-film jam device is provided downstream of the extrusion of the first roller and the second roller, and the anti-film jam device includes a thin sheet inserted into the annular narrow groove and a plate provided at the root of the thin sheet, and the root of the thin sheet is not lower than the side of the plate.

[0004] The above device can reduce the warping of the diaphragm due to heat and then roll it onto the first roller and the second roller, but there are still shortcomings: the thin sheet and the upper and lower side panels are made of different materials and are separate parts. During assembly, they need to be independently assembled through glue or connectors. The assembly process is inefficient and the thin sheet is constantly subjected to force during use, which makes it easy to separate from the side panels, resulting in structural failure. Summary of the Invention

[0005] The utility model aims at solving the above problems existing in the prior art and provides an anti-jamming structure for a laminating machine. The utility model aims to solve the technical problem that the anti-jamming structure for the prior art laminating machine has low manufacturing efficiency and weak stability.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A laminating machine anti-stuck structure includes an anti-stuck vertical plate and a plurality of upper anti-stuck plates and lower anti-stuck plates located on the anti-stuck vertical plate, wherein the upper anti-stuck plates and the lower anti-stuck plates are both vertically arranged and extend toward one side of the anti-stuck vertical plate, and is characterized in that the anti-stuck vertical plate has a strip hole that passes through both sides of the anti-stuck vertical plate and is arranged in a horizontal direction, and the upper anti-stuck plates and the lower anti-stuck plates are respectively integrally connected to the upper edge and the lower edge of the strip hole.

[0008] The anti-jamming vertical plate is arranged downstream of the upper and lower rubber rollers. The upper anti-jamming plate and the lower anti-jamming plate extend towards the side where the upper and lower rubber rollers are arranged to be respectively embedded in the annular grooves on the outer circumferences of the upper and lower rubber rollers to provide limit, so that the rubber film will not be wound onto the rubber rollers and interference with the rotation of the rubber rollers is avoided. By arranging strip-shaped holes on the anti-jamming vertical plate and integrally connecting the upper anti-jamming plate and the lower anti-jamming plate to the upper and lower edges of the strip-shaped holes respectively, the upper anti-jamming plate and the lower anti-jamming plate can be formed by means of integral plate cutting and bending or integral injection molding, which is an integral component, eliminating the process of assembling split parts, and the connection between the upper anti-jamming plate and the lower anti-jamming plate and the anti-jamming vertical plate is more stable, taking into account both manufacturing efficiency and working stability.

[0009] In the anti-jamming structure of the above laminator, the upper anti-jamming plate and the lower anti-jamming plate are arranged in a staggered manner along the length direction of the strip-shaped hole. In this way, for the process of integral plate cutting and bending, it is beneficial to enable the upper anti-jamming plate and the lower anti-jamming plate to make full use of the materials in the strip-shaped hole area, avoid material waste, and enable the sizes of the upper anti-jamming plate and the lower anti-jamming plate to meet the requirements of stable operation.

[0010] In the anti-jamming structure of the above laminator, the upper and lower inner walls of the strip-shaped hole respectively have a plurality of upper suspension plates and lower suspension plates that are bent towards the side where the upper anti-jamming plate extends. The plurality of upper suspension plates and lower suspension plates are arranged at intervals along the length direction of the strip-shaped hole. The upper suspension plate is perpendicular to the upper anti-jamming plate, and the lower suspension plate is perpendicular to the lower anti-jamming plate. Bending the upper suspension plate and the lower suspension plate in this way is beneficial to increasing the smoothness of the upper and lower edges of the strip-shaped hole. In addition, the upper suspension plate and the lower suspension plate can provide support and limit for the warped rubber film, enabling it to pass through the strip-shaped hole smoothly.

[0011] In the anti-jamming structure of the above laminator, the upper suspension plate and the lower suspension plate are inclined in a direction away from each other vertically. In this way, the upper suspension plate and the lower suspension plate cooperate to form a flared shape as a whole, which is beneficial to making the rubber film more likely to come into contact with the upper suspension plate or the lower suspension plate and be guided by them when the rubber film warps, and then pass through the anti-jamming vertical plate smoothly.

[0012] In the anti-jamming structure of the above laminator, the upper anti-jamming plate is integrally connected to the side of the upper suspension plate opposite to the adjacent upper suspension plate, and the lower anti-jamming plate is integrally connected to the side of the lower suspension plate opposite to the adjacent lower suspension plate. In this way, the root of the upper anti-jamming plate is located on the side edge of the upper suspension plate, and using the upper suspension plate as a step is beneficial to enabling the upper anti-jamming plate to be closer to the position where the rubber film passes. Similarly, it is also beneficial to enable the lower anti-jamming plate to be closer to the position where the rubber film passes, which can provide more accurate and stable limit for the rubber film and prevent jamming.

[0013] As another solution, the protruding ends of the upper anti-jamming plate and the lower anti-jamming plate respectively extend beyond the upper suspension plate and the lower suspension plate. The bottom of the upper suspension plate is lower than the upper anti-jamming plate, and the lower edge of the upper anti-jamming plate is lower than the high point of the bottom surface of the upper suspension plate. The top of the lower suspension plate is higher than the lower anti-jamming plate, and the upper edge of the lower anti-jamming plate is higher than the low point of the top surface of the lower suspension plate. In this way, after the adhesive film passes through the upper and lower rubber rollers, it will first contact the upper anti-jamming plate or the lower anti-jamming plate to avoid jamming. Then, when the adhesive film continues to be conveyed, it will be supported and constrained by the larger-area upper suspension plate or lower suspension plate, avoiding obvious scratches caused by the continuous contact of the adhesive film with the thinner upper anti-jamming plate or lower anti-jamming plate, and ensuring the plastic sealing quality.

[0014] In the anti-jamming structure of the above laminator, the protruding ends of the upper anti-jamming plate and the lower anti-jamming plate are both processed with rounded corners. This helps to avoid scratching and interference of the sharp edges of the upper anti-jamming plate and the lower anti-jamming plate on the upper and lower rubber rollers, and avoids the hindrance of rotation.

[0015] As another solution, the upper and lower inner walls of the strip-shaped hole are respectively provided with a plurality of upper suspension plates and lower suspension plates that are bent toward the side away from the protruding side of the upper anti-jamming plate. The plurality of upper suspension plates and lower suspension plates are all arranged at intervals along the length direction of the strip-shaped hole. The upper suspension plate is perpendicular to the upper anti-jamming plate, and the lower suspension plate is perpendicular to the lower anti-jamming plate. In this way, the adhesive film can still be supported by the upper suspension plate or the lower suspension plate when passing through the strip-shaped hole, which helps to make the adhesive film be conveyed smoothly.

[0016] In the anti-jamming structure of the above laminator, baffles are provided on both the upper and lower sides of the anti-jamming vertical plate and are bent toward the side where the upper anti-jamming plate protrudes. In this way, the baffles can provide effective protection for the upper and lower rubber rollers, and thus ensure the stable operation of the rubber rollers.

[0017] In the anti-jamming structure of the above laminator, the anti-jamming vertical plate is a stamping metal plate part. This helps to ensure the structural strength of the upper anti-jamming plate or the lower anti-jamming plate itself, and the stamping and bending process has high processing efficiency, taking into account both the manufacturing efficiency and the structural stability.

[0018] Compared with the prior art, the advantages of the present utility model are as follows:

[0019] The upper anti-jamming plate and the lower anti-jamming plate in the anti-jamming structure of this laminator are of an integrally formed structure, eliminating the process of assembling split parts, and the connection between the upper anti-jamming plate and the lower anti-jamming plate and the anti-jamming vertical plate is more stable, taking into account both the manufacturing efficiency and the working stability.
