Abstract
Description
Technical Field
[0001] This utility model relates to a waste recycling and stripping device for PTC auxiliary electric heaters. Background Technology
[0002] PTC auxiliary electric heaters are widely used in household appliances such as air conditioners and space heaters, and their scrap volume is increasing year by year. Scrapped PTC heaters are typically made of aluminum alloy heat sinks, PTC ceramic heating elements, and high-temperature resistant adhesive layers pressed together.
[0003] Currently, most recycling methods involve first heating the entire piece to around 200°C to soften the adhesive layer, then manually peeling off the heat sink fins piece by piece using chisels and pry bars. This method is labor-intensive, inefficient (taking about 5-8 minutes per piece), and the high temperature environment can easily cause burns to operators. The adhesive fumes also pose occupational health hazards.
[0004] Therefore, a PTC-assisted electric heater waste recycling and stripping device is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a waste recycling and stripping device for PTC auxiliary electric heaters, so as to solve the problems of high labor intensity and low efficiency in the current PTC auxiliary electric heater waste recycling process mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PTC auxiliary electric heater waste recycling and stripping device, comprising: a recycling workbench; A guide assembly, mounted on the upper part of the recycling workbench, is used to guide the waste from the PTC auxiliary electric heater in a straight line; and A stripping assembly, installed at the lower part of the recycling workbench and directly below the guide assembly, is used to cut and strip the guided PTC auxiliary electric heater waste.
[0007] Preferably, the guide assembly includes two sets of fixing plates, each set of fixing plates is "L" shaped and has a vertical arm and a horizontal arm, the horizontal arm extends inward and is fixedly connected to the recycling workbench by fixing bolts; Both sets of vertical arms are provided with guide plates on their inner sides, and a guide channel is formed between the two sets of guide plates to match the width of the waste product of the PTC auxiliary electric heater.
[0008] Preferably, an adjusting bolt is provided between the guide plate and the corresponding vertical arm. The screw end of the adjusting bolt passes through the vertical arm and pushes against the guide plate to change the distance between the two guide plates.
[0009] Preferably, a plurality of pressure rollers are provided between the two sets of fixed plates. The axis of the pressure rollers is perpendicular to the guide direction, and a gap is left between the outer peripheral surface of the pressure rollers and the top surface of the guide plate for the PTC auxiliary electric heater waste to pass through. The pressure rollers are used to limit the PTC auxiliary electric heater waste in the height direction.
[0010] Preferably, the stripping assembly includes a support frame fixed below the recycling workbench, and the support frame is connected to a support seat by height adjustment bolts to adjust the height of the support seat relative to the recycling workbench; The support base is equipped with a saw box, and a stripping motor is installed inside the saw box. The output end of the stripping motor is equipped with a saw blade to directly drive the saw blade to rotate.
[0011] Preferably, the tail end of the height adjusting bolt is provided with a pin. After the pin is inserted into the corresponding positioning hole of the bearing seat, it is locked by a cotter pin to prevent the height adjusting bolt from loosening from the bearing seat.
[0012] Preferably, the height adjusting bolt is further threaded with a fixing nut, which is locked onto the lower surface of the support seat after the height adjustment is completed, so as to maintain the height of the support seat unchanged. The height adjusting bolt is connected to the support frame via threads, and rotating the height adjusting bolt causes the support seat to be lifted through the support frame.
[0013] Preferably, the recycling workbench has a through-saw groove at the position directly opposite the saw blade, and the upper edge of the saw blade passes through the saw groove and protrudes from the upper surface of the recycling workbench to complete the cutting and stripping when the waste from the PTC auxiliary electric heater is guided and moved.
[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a peeling component to directly cut the high-temperature resistant adhesive layer at room temperature using a rotating saw blade, eliminating the need for overall heating to 200°C, reducing energy consumption by 80%, and completely eliminating the risk of high-temperature fumes and burns to operators.
[0015] The guide assembly forms a straight guide channel, which, together with the pressure roller, allows for continuous feeding and continuous rotation of the saw blade for cutting, realizing a "push-in - cut-out" assembly line operation, increasing efficiency by more than 10 times.
[0016] The saw blade only cuts the glue layer connection, and the heat dissipation strip retains its original sheet shape, avoiding the problems of metal inclusion and surface glue accumulation caused by traditional crushing methods. Subsequent remelting does not require refining, and the recovery rate is increased by 10-15 percentage points.
[0017] The adjusting bolt can steplessly change the distance between the two guide plates; the height adjusting bolt can raise and lower the saw blade within a certain range to adapt to waste products of different thicknesses, without the need for additional tooling, thus solving the pain point of "single-specification special machine".
[0018] The height adjustment bolt end uses a "pin + cotter pin" to prevent loosening, and is tightened with a fixing nut to eliminate saw blade sinking caused by vibration and avoid damage to the ceramic blade or glue residue caused by "cutting depth drift". Attached Figure Description

[0021] To address the current problems of high labor intensity and low efficiency in the recycling of PTC auxiliary electric heater waste, this utility model provides a PTC auxiliary electric heater waste recycling and stripping device. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0022] Please see Figure 1-5 This utility model provides a recycling workbench 1; A guide assembly 2, installed on the upper part of the recycling workbench 1, is used to guide the waste from the PTC auxiliary electric heater in a straight line. The guide assembly 2 includes two sets of fixing plates 21, each set of fixing plates 21 being "L"-shaped, having a vertical arm 211 and a horizontal arm 212. The horizontal arm 212 extends inward and is fixedly connected to the recycling workbench 1 by fixing bolts 22. Guide plates 23 are provided on the inner sides of both sets of vertical arms 211, forming a guide channel 24 between the two sets of guide plates 23 that is adapted to the width of the waste from the PTC auxiliary electric heater. An adjusting bolt 25 is provided between the guide plate 23 and the corresponding vertical arm 211. The screw end of the adjusting bolt 25 passes through the vertical arm 211 and pushes against the guide plate 23 to change the distance between the two guide plates 23. A plurality of pressure rollers 26 are provided between the two sets of fixed plates 21. The axis of the pressure rollers 26 is perpendicular to the guide direction, and a gap is left between the outer peripheral surface of the pressure rollers 26 and the top surface of the guide plate 23 for the PTC auxiliary electric heater waste to pass through. The pressure rollers 26 are used to limit the PTC auxiliary electric heater waste in the height direction.
[0023] And the stripping component 3, installed at the lower part of the recycling workbench 1 and located directly below the guide component 2, is used to cut and strip the PTC auxiliary electric heater waste after it has been guided.
[0024] The stripping assembly 3 includes a support frame 31 fixed below the recycling workbench 1. The support frame 31 is connected to a support seat 33 via a height adjustment bolt 32 to adjust the height of the support seat 33 relative to the recycling workbench 1. A saw box 34 is mounted on the support seat 33, and a stripping motor is installed inside the saw box 34. A saw blade 36 is mounted at the output end of the stripping motor to directly drive the saw blade 36 to rotate. The tail end of the height adjustment bolt 32 is provided with a pin 321. After the pin 321 is inserted into the corresponding positioning hole of the support seat 33, it is locked by a cotter pin 35 to prevent the height adjustment bolt 32 from loosening from the support seat 33. A fixing nut 37 is also threaded onto the outer periphery of the height adjustment bolt 32. After the height is adjusted to the correct position, the fixing nut 37 is locked onto the lower surface of the support seat 33 to maintain the height of the support seat 33.
[0025] The recycling workbench 1 has a through-saw groove 38 directly opposite the saw blade 36. The upper edge of the saw blade 36 passes through the saw groove 38 and protrudes from the upper surface of the recycling workbench 1 to complete the cutting and stripping when the waste from the PTC auxiliary electric heater is guided and moved.
[0026] The working principle of the PTC auxiliary electric heater waste recycling and stripping equipment provided by this utility model is as follows: Width adjustment: Simultaneously rotate the adjusting bolts 25 located on both sides of the fixed plate 21, so that the adjusting bolts 25 abut against the two sets of guide plates 23 and move, controlling the distance between the two sets of guide plates 23 to match the width of the PTC auxiliary electric heater waste, so that the PTC auxiliary electric heater waste can move linearly through the distance between the two sets of guide plates 23.
[0027] Thickness / cutting depth adjustment: First, loosen the fixing nut 37, rotate the height adjusting bolt 32, which is connected to the support frame 31 via threads. Rotating the height adjusting bolt 32 will lift the support seat 33 through the support frame 31 until the upper edge of the saw blade 36 protrudes from the upper surface of the recovery worktable 1, allowing the upper edge of the saw blade 36 to cut the adhesive layer. Then, tighten the fixing nut 37 and insert the cotter pin 35 to prevent loosening.
[0028] Start the stripping motor to rotate the saw blade 36, pushing the PTC heater waste along the guide channel 24 until the front end touches the saw blade 36. Manually advance at a uniform speed, while the pressure roller 26 automatically presses the upper surface of the waste to prevent jumping during cutting. This cuts the adhesive layer within the saw groove 38, separating the aluminum alloy heat sink from the PTC ceramic sheet.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
