Description

Technical Field

[0001] This utility model relates to the field of heat sealing device technology, specifically a heat sealing device for coated paper that is easy to transport. Background Technology

[0002] Coated paper is a composite material made by casting plastic particles into a thin film and then heat-sealing the film evenly onto the surface of paper. Its main characteristics are oil and water resistance, and it is widely used in packaging, catering and other industries.

[0003] In current coated paper production workshops, heat sealing is mainly achieved through roller heat sealing, where two sets of relatively rotating heated rollers press the plastic film and the substrate together. However, this method has some functional shortcomings and room for improvement in actual use. For example, the heat sealing of coated paper involves the supply and conveying of two sets of materials: one set of plastic film from the casting machine and the other set of base paper. The height of the release mechanism for the two sets of materials depends on the model of the corresponding equipment, while the height of the raw material conveying guide roller of the heat sealing machine is fixed. This can easily lead to mismatch in equipment height, affecting the normal feeding process and lacking the function of adjusting the roller height for easy conveying.

[0004] Now, a novel heat-sealing device for coated paper that is easy to transport is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat-sealing device for coated paper that is easy to transport, so as to solve the problem mentioned in the background art that it does not have the function of adjusting the roller height for easy transport.

[0007] The conveying assembly includes two sets of I-beams, which are vertically fixed to the front and rear ends of the top of the concave support frame. Multiple sets of internal thread positioning holes are opened on the left and right sides of the I-beams. Slider blocks are sleeved on the left and right sides of the outside of the I-beams. A roller mounting bracket is welded to the middle position of the outer side of the slider. A conveying guide roller is movably connected between the two sets of roller mounting brackets. Internal thread tube seats are fixedly connected to the upper and lower ends of the outer side of the slider. Positioning bolts are inserted laterally inside the internal thread tube seats.

[0008] As a further technical solution of this utility model, the I-shaped frame is symmetrically distributed about the vertical center line of the concave support frame, and the internal thread positioning holes are arranged at equal intervals.

[0009] As a further technical solution of this utility model, the shape and size of the outside of the I-shaped frame are adapted to the shape and size of the inside of the slider, and the slider can slide up and down along the outside of the I-shaped frame.

[0010] As a further technical solution of this utility model, the external thread of the positioning bolt matches the internal thread positioning hole and the internal thread of the internal thread pipe seat, and the positioning bolt passes through the slider and the internal thread pipe seat and extends into the interior of the internal thread positioning hole.

[0011] As a further technical solution of this utility model, the blower passes through both the inner and outer sides of the side mounting plate, there is a distance between the heat sealing roller and the heating wire, and the PLC controller, the heating wire and the blower are electrically connected.

[0012] As a further technical solution of this utility model, hand-tightening bolts are inserted into the four corners of the outer side of the side mounting plate, and handles are fixedly connected to the upper and lower ends of the outer side of the side mounting plate. The hand-tightening bolts pass through the side mounting plate and extend into the interior of the side shell. The handles are symmetrically distributed about the horizontal center line of the side mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-carry coated paper heat sealing device not only realizes the function of adjusting the roller height for easy conveying, but also realizes the function of easy temperature control and heating, and also realizes the function of easy disassembly and maintenance.

[0014] Equipped with an I-shaped frame, internal thread positioning holes, sliders, roller mounting brackets, conveyor guide rollers, internal thread pipe seats, and positioning bolts, the two sets of conveyor guide rollers, one guiding the plastic film pulled from the casting machine and the other guiding the base paper, can be adjusted according to the height of the base paper release mechanism and the release mechanism of the casting machine.

[0033] Working Principle: In use, this invention firstly uses two sets of conveying guide rollers 11. One set guides the plastic film pulled from the casting machine, and the other set guides the base paper. The actual height of the two sets of conveying guide rollers 11 can be adjusted according to the height of the base paper release mechanism and the release mechanism of the casting machine. Loosening the positioning bolts 13 on the internal threaded tube seat 12 disengages it from the internal threaded positioning hole 8. The slider 9, along with the conveying guide rollers 11, can then slide up and down along the outside of the I-beam frame 7 for adjustment. Multiple sets of internal threaded positioning holes 8 provide various adjustment options. A suitable height for the conveying guide rollers 11 ensures smoother and more efficient material conveying. The blower 19 blows air into the side shell 6, transferring heat from the heating wire 17 to the heat-sealing roller 4 via the airflow, raising its temperature. The temperature of the heat-sealing roller 4 can be quickly adjusted by adjusting the output power of the heating wire 17 and the blower 19. The equipment has a small footprint and requires no additional oil heating equipment. The infrared temperature sensor 15 on the sensor fixing plate 14 monitors the temperature of the heat-sealing roller 4 in real time and displays the value on the LCD screen 16 for easy viewing and adjustment. As the core heating components, the heating wire 17 and the blower 19 can be removed as a whole when one of them is damaged. Alternatively, the hand-tightening bolts 20 on the side mounting plate 18 can be loosened and pulled out, and the side mounting plate 18 can be removed individually by grasping the handle 21, making maintenance more flexible and convenient.
