Description

Technical Field

[0001] The present application relates to the technical field of solvent-free laminating machines, and in particular to a material discharge mechanism for a hydraulic solvent-free laminating machine. Background Art

[0002] A solventless laminating machine uses solventless adhesives to combine two or more substrates. Its main components include a first unwinding unit, a coating unit, a second unwinding unit, a laminating unit, and a winding unit. Lamination of the two substrates is accomplished through a process of unwinding, coating, laminating, and winding. Currently, most substrates are film materials. A roll of film is relatively light, and the unwinding or winding unit uses a clamping method that uses two arms extending in the same direction from the solventless laminating machine to clamp the film. The arms are equipped with a core tube that secures the roll of film, and the rotation of the head drives the film to be retracted and released. However, with increasing demands on packaging materials, paper and plastic sheets are increasingly being used as substrates. The weight of the same volume of paper or plastic is several times greater than that of film. As a result, the clamping method used by existing solventless laminating machines for film materials is unsuitable for heavy paper or plastic sheets. Utility Model Content

In the discharging mechanism, the unwinding roller is clamped by the clamping arms 31. The clamping arms 31 are slidably adjusted on the mounting bracket 3 and fixed to the mounting bracket 3 by a locking mechanism, thereby meeting the installation requirements of unwinding rollers of different lengths. A hydraulic cylinder 11 connected between the top of the unloading base 1 and the mounting bracket 3 drives the mounting bracket 3 to rotate, enabling the unloading mechanism to switch between the working position and the loading and unloading position. An adjustment base 2 mounted at the bottom of the unloading base 1 allows the mounting bracket 3 in the unloading mechanism to be adjusted laterally, thereby aligning with the overall position of the multifunction machine.

[0026] Reference Figure 1 The adjustment seat 2 includes a base 21 with a first slide rail 211 installed on the top, and a first slider 12 installed at the bottom of the discharge base 1, wherein the first slider 12 can move along the length direction of the discharge base 1 on the first slide rail 211. The adjustment seat 2 is installed at the bottom of both ends of the discharge base 1, wherein the length of the base 21 at both ends of the adjustment seat 2 is less than the length of the discharge base 1. Support legs 22 are installed at the four top corners of the base 21, wherein the height of the support legs 22 is adjustable. The first slider 12 at the bottom of the discharge base 1 can slide on the first slide rail 211 on the base 21, and the width of the adjustment seat 2 is greater than the discharge base 1, which can stably install the discharge base 1, and can realize the lateral short-distance adjustment of the discharge mechanism during installation. And height-adjustable support legs 22 are installed around the bottom of the base 21, which can meet the installation requirements of the adjustment seat 2 in different environments.

[0027] Reference Figure 1 and Figure 2The mounting bracket 3 includes a back plate 33 and side plates 34 mounted at both ends of the back plate 33, wherein the side plates 34 are rotatably mounted on the inner sides of the discharge base 1 on both sides, and the back plate 33 is mounted with a second slide rail 331 that slides in cooperation with the second slider 311 on the clamping arm 31. The back plate 33 is also mounted with an adjustment screw 332 distributed along its length, wherein one end of the adjustment screw 332 passes through the side plate 34 and the discharge base 1, and the other end is rotatably mounted on the bearing seat 333 on the back plate 33.
