Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and in particular to an edge banding machine heating device. Background Technology

[0002] An edge banding machine is a device specifically designed for woodworking edge banding. It is widely used in the edge banding of wooden cabinets, wooden tables and chairs, and other wooden furniture. At the same time, the edge banding machine can use special settings and structures to apply glue to both the workpiece and the edge banding strip, making the adhesion between the edge banding strip and the board stronger.

[0003] In existing plate edge banding processes, due to the low indoor temperature and large temperature difference in winter, the edge banding strip becomes harder and more brittle at low temperatures, often resulting in poor adhesion. Existing technologies typically use edge banding preheating devices to heat the edge banding strip. However, after the edge banding machine stops working, the residual heat from the preheating device continues to heat the edge banding strip remaining inside the machine. The edge banding strip will be damaged by prolonged exposure to the high temperature of residual heat. Existing technologies use fans for heat dissipation, which consumes too much energy.

[0004] CN 220699939 U discloses a preheating device for edge banding processes, comprising two sets of support frames, with fixed plates fixedly mounted on the two sets of support frames. Two sets of mounting plates are movably mounted on the fixed plates, and a preheating mechanism is provided on each mounting plate. A heat insulation mechanism is provided on the two sets of support frames. This edge banding preheating device, through the cooperation of a heating pipe and a heat-conducting plate in the preheating mechanism, preheats the edge banding strip, preventing it from becoming harder and more brittle at low temperatures, thus preventing poor adhesion. When the edge banding machine is turned off, a cylinder pushes the base plate upwards, causing a top rod to push the mounting plates open to both sides. This moves the heat insulation cover and heat insulation layer upwards between the two sets of heat-conducting plates, placing the edge banding strip inside the heat insulation layer. This prevents the edge banding strip from being damaged by prolonged exposure to high temperatures from residual heat. Furthermore, the use of a cylinder for pushing achieves physical temperature isolation, without consuming a large amount of electrical energy.

[0005] However, even when the edge banding preheating device isolates the edge banding from the preheating mechanism through the heat insulation cover, some of the heat from the preheating mechanism will still pass through the heat insulation cover to heat the edge banding, which may cause damage to the edge banding. Furthermore, the edge banding preheating device lacks a limiting device for the edge banding, which may cause the edge banding to shake when passing between the two sets of heat-conducting plates, resulting in direct contact between the edge banding and the heat-conducting plates, causing the edge banding to be damaged due to high temperature. Utility Model Content

[0006] In order to overcome the above-mentioned defects in the prior art, this utility model provides a heating device for an edge banding machine.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a heating device for an edge banding machine, including two sets of support frames, a fixed plate fixedly installed on the top of the two sets of support frames, and mounting plates that can be raised and lowered at the front and rear ends of the fixed plates.

Guide sliders are slidably installed on the guide slide rails, and connecting frames are fixedly installed on the guide sliders. The connecting frames are fixedly installed at the bottom of the mounting plate.

[0009] Furthermore, the fixing plate has mounting slots at both the front and rear ends, the first cylinder is located on either the left or right side of each set of mounting slots, the first cylinder is fixedly installed on the top of the fixing plate, the power output end of the first cylinder is fixedly installed with a first push plate, the first push plate is fixedly installed on the bottom of the mounting plate, and the mounting plate is located inside the mounting slot.

[0010] Furthermore, the top of the left and right ends of the mounting groove is provided with a limiting platform, and the top wall of the mounting plate is provided with grooves that match the limiting platform at the left and right ends.

[0011] Furthermore, the mounting plate is provided with several sets of sliding grooves, and the bottom of the preheating component is fixedly installed with a slider that matches the sliding groove.

[0012] Furthermore, a contact switch is fixedly installed on the top side of the mounting plate away from the middle of the fixing plate.

[0013] Furthermore, the fixed roller assembly includes a fixed roller, which is rotatably mounted on a first bearing seat.

[0014] Furthermore, springs are fitted onto each of the two sets of guide rods, with the two ends of the springs abutting against the second bearing seat and the second mounting bracket, respectively. A baffle is fixedly installed on the end of each set of guide rods away from the movable roller, and a handle is fixedly installed on the baffle.

[0015] The beneficial effects of this utility model are:

[0016] 1. The design of this utility model is based on the design of mounting plates that can be raised and lowered at both ends of the fixed plate.

When the edge banding machine is working, the edge banding strip passes between the fixed roller 19 and the movable roller 22. The movable roller 22 cooperates with the fixed roller 19 to clamp the two ends of the edge banding strip, so that the part of the edge banding strip located between the preheating components 5 is in a straight state, thereby avoiding the edge banding strip from shaking during operation, and thus preventing the edge banding strip from directly contacting the preheating components.
