Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a hot pressing device of a laminating machine. Background Art

[0002] Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. They are special equipment for paper, board materials, and film mounting. After being pressurized by rubber rollers and heating rollers, they are combined to form a paper-plastic product. When existing laminating machines laminate materials, the materials are placed on the machine table, and the materials are moved by conveyor belts so that the materials pass through hot pressing equipment for lamination. However, the position of the materials is not limited during the movement of the materials. When the material position is not aligned, the laminating effect will be unsatisfactory, affecting subsequent use.

[0003] An existing hot pressing device of a laminating machine (Announcement No.: CN219583530U) has at least the following disadvantages: the device can support and fix the position of the bidirectional hydraulic rod by setting the second fixed block, and by setting the bidirectional hydraulic rod and the third fixed block, the bidirectional hydraulic rod is started, and the bidirectional hydraulic rod can drive the third fixed block to move. When the third fixed block moves, it can drive the moving block to slide on the side wall of the sliding rod, so as to limit the material. However, the device realizes the limiting function through the bidirectional hydraulic rod. Since the width of the material may be different, the bidirectional hydraulic rod needs to be constantly adjusted, which reduces the work efficiency. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a heat pressing device for a laminating machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hot pressing device for a laminating machine comprises a general mounting frame, a transmission belt is installed on the general mounting frame, a mounting beam is welded and fixed at a position near the front end of the top surface of the general mounting frame, a cylinder is installed in the middle of the top surface of the crossbeam of the mounting beam, the telescopic end of the cylinder is connected with a positioning assembly, the positioning assembly comprises a mounting plate, a fixing plate 1 is integrally formed on the mounting plate, a mounting arm is welded and fixed to the rear of the mounting beam on the general mounting frame, a mounting bracket is slidably installed on the mounting arm, a hot pressing roller is rotatably installed on the mounting bracket, the rotating shaft of the hot pressing roller passes through the mounting bracket and is coaxially connected to a motor, a fixing plate 2 is integrally formed on the mounting bracket, and the fixing plate 2 is connected to the fixing plate 1 through a linkage plate.

[0007] As a further solution of the utility model, two sliding grooves are symmetrically provided on the mounting plate, active sliders are slidably connected in the two sliding grooves, and connecting rods are hinged on the top surfaces of the two active sliders.

[0008] As a further solution of the utility model, two hinge blocks are symmetrically provided on the bottom surface of the mounting beam on both sides of the cylinder, and ends of the two connecting rods away from the active slider are respectively hinged to the two hinge blocks.

[0009] As a further solution of the utility model, driven sliders are slidably connected in both slide grooves, and the driven sliders are connected to the active slider via spring 1, and spring 1 can enable the driven sliders to adapt to materials of different widths.

[0010] As a further solution of the utility model, a through square groove is provided on the top surface of the driven slider, and sliding limit plates are slidably inserted in the square grooves of the two driven sliders, and the bottom surface of the limit clamp plate abuts against the top surface of the transmission belt.

[0011] As a further solution of the utility model, the sliding limit plate includes a square column, the bottom surface of the square column is integrally formed with a limit clamp, the top surface of the square column is integrally formed with a blocking block, the outer wall of the square column is sleeved with a second spring, the top surface of the second spring abuts against the bottom surface of the driven slider, the bottom surface of the second spring abuts against the top surface of the limit clamp, and the second spring can reset the sliding limit plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The device drives the mounting plate downward through the cylinder, and the two active sliders move toward each other under the action of the connecting rod. At the same time, the active slider drives the driven slider and the sliding limit plate to move toward each other through the spring until the side walls of the two limit clamps abut against the material. The spring is stretched and the two limit clamps limit the material. During this process, the mounting plate drives the mounting bracket to move downward synchronously through the linkage plate until the outer wall of the hot pressing roller installed on the mounting bracket abuts against the material, the cylinder stops working, and the motor drives the hot pressing roller to rotate and coat the material. The device provides a stretching spring to allow the sliding limit plate to move with plenty of margin, so that materials of different widths can be limited and clamped, reducing manual adjustment and improving work efficiency. At the same time, the limit device is connected to the hot pressing device through a linkage rod, reducing the use of circuit components and reducing production costs.
