Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a positioning device for cardboard lamination. Background Technology

[0002] Cardboard lamination is a process that coats the surface of cardboard with a thin film to enhance its appearance, protective properties, and durability. It is commonly used in packaging boxes, book covers, and other applications. Lamination makes the cardboard surface smooth, waterproof, abrasion-resistant, and stain-resistant, improves printing quality and results, extends the cardboard's lifespan, and enhances its protective properties and aesthetic appeal. During the cardboard lamination process, a positioning device is required to hold the cardboard in place.

[0003] Current positioning devices typically use clamping to position the cardboard, which can easily cause bending and deformation, affecting the lamination effect. Furthermore, they are not convenient for leveling the cardboard, and uneven cardboard surfaces also negatively impact the lamination result. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for cardboard lamination, which solves the problem of insufficient positioning effect of cardboard and the problem that uneven cardboard surface will affect the lamination effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for cardboard lamination, comprising a base plate, a support rod fixedly connected to the bottom of the base plate, an anti-slip pad fixedly connected to the bottom of the support rod, a plurality of evenly distributed fixing rods fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the fixing rods, two symmetrically distributed pressure rollers contacting the upper end of the base plate, a bracket hinged to the outer side of the pressure rollers, a positioning mechanism provided on the bracket, and a leveling mechanism provided on the positioning mechanism;

[0006] The positioning mechanism includes two symmetrically distributed hinged rods. A hinged rod is fixedly connected to the top of the bracket. A hinged seat is hinged to the outer side of each hinged rod. A fixing block is fixedly connected inside the hinged seat. A guide block is fixedly connected inside each fixing block. A connecting frame is slidably sleeved on the outer side of each guide block. A guide rod is fixedly connected inside each connecting frame. A spring is provided on the outer side of each guide rod. The guide rod is slidably connected to the guide block. A pulley is hinged inside the connecting frame on the side away from the guide block, and the pulley contacts the hinged rod. By designing this positioning mechanism, cardboard can be clamped and positioned.

[0007] The leveling mechanism includes two symmetrically distributed connecting rods. A connecting rod is fixedly connected to the top of the hinged seat. The connecting rod is slidably connected to the top plate. A double-threaded rod is threaded inside the connecting rod. A rotating seat is rotatably connected to the outer side of the double-threaded rod via a bearing. The rotating seat is fixedly connected to the top plate. A drive motor is fixedly mounted on the top of the top plate. The output shaft of the drive motor passes through one of the rotating seats and is fixedly connected to the double-threaded rod. A guide rod is slidably sleeved inside the connecting rod. By designing this leveling mechanism, cardboard can be leveled.

[0008] Preferably, there are multiple support rods, which are evenly distributed at the lower end of the base plate. By designing support rods, the overall structure can be supported.

[0009] Preferably, one end of the spring is fixedly connected to the guide block, and the other end of the spring is fixedly connected to the connecting frame. The spring is designed so that its force can be applied to the guide block.

[0010] Preferably, the top plate has a through groove inside, which slides with the connecting rod. This through groove design allows the connecting rod to slide inside the top plate.

[0011] Preferably, both ends of the guide rod are fixedly connected to a mounting base, and the mounting base is fixedly connected to the top plate. The mounting base provides support for the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of the pressure roller, allows the cardboard to be placed between the base plate and the pressure roller after the deflection of the pressure roller and the support. The deflection of the hinge rod can squeeze and push the pulley. When the pressure roller is lowered and contacts the cardboard, the elasticity of the spring can press down and tighten the cardboard. The use of elastic pressing can effectively avoid the deformation of the cardboard caused by the clamping and positioning method, which affects the lamination effect.

[0014] 2. This utility model, through the design of a drive motor, enables the output end of the drive motor to drive the bidirectional threaded rod to rotate, thereby realizing the threaded movement of the connecting rod. The movement of the connecting rod can drive the hinge seat, hinge rod bracket and pressure roller to move horizontally. The pressure roller can level the paperboard by rolling along it, thereby improving the coating effect on the paperboard. Attached Figure Description
