Technical Field

[0001] The invention belongs to the technical field of foam sheets, and in particular relates to an XPE foam sheet thinning processing device. Background Art

[0002] XPE foam sheet is a new type of environmentally friendly material with excellent performance, and has multiple advantages such as flame retardancy, insulation, waterproof and moisture-proof, shock absorption, heat preservation and anti-aging. It is widely used in automotive interior, electronic component shock absorption, luggage production and children's toys, etc., showing broad market prospects and extremely high practical value.

[0003] In the traditional XPE foam sheet thinning process, mechanical thinning equipment is usually used. However, traditional equipment has many shortcomings, such as low efficiency in adjusting the gap between the rolling rollers and low adjustment accuracy, making it difficult to meet the requirements of sheet thinning with different thicknesses. At the same time, the thinning effect on XPE foam sheets is relatively general. Summary of the invention

[0007] Furthermore, the cooling assembly includes a fan bracket, the fan bracket is connected to the support frame by screws, and a plurality of cooling fans are installed inside the fan bracket.

[0008] Furthermore, the slider is connected to the screw motor through the lifting of the screw, and the slider is slidably connected to the mounting frame.

[0009] Furthermore, an oblique conveying pipe is fixedly provided at the bottom of the residual material tray, and the residual material tray is connected to the supporting frame by screws.

[0012] Beneficial effects: The invention is reasonably designed and has the following beneficial effects:

[0013] 1. In the scheme of the present invention, the slider is driven up and down by the screw motor to accurately adjust the gap between the first laminating roller and the second laminating roller, thereby realizing accurate control of the thinning thickness. Compared with the manual adjustment or rough mechanical adjustment in the conventional technology, this design has higher accuracy and stability, and can meet the thinning processing of sheets with different thickness requirements;

[0014] 2. In the scheme of the present invention, a heating frame is provided before the thinning mechanism, and the sheet is preheated by an electric heating plate to soften it and make it easier to be thinned.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Combination Figures 1 to 3 An XPE foam sheet thinning processing equipment shown in the figure includes a support frame 1, a thinning mechanism 2 is provided on the inner side of the support frame 1, the thinning mechanism 2 includes a first rolling roller 201 and a second rolling roller 202, mounting frames 203 are provided at both ends of the first rolling roller 201 and the second rolling roller 202, screw motors 204 are installed on the top of the two mounting frames 203, sliders 205 are provided at both ends of the first rolling roller 201 and are connected through a rotating shaft, a residual material tray 3 is provided under the thinning mechanism 2, feed rollers 4 are provided on both sides of the mounting frame 203, and the two feed rollers 4 are connected to the support frame 1 through a rotating shaft, a heating frame 5 is provided between one of the feed rollers 4 and the thinning mechanism 2, and a cooling component 6 is provided under the other feed roller 4.

[0023] Among them, the two ends of the heating frame 5 are connected to the support frame 1 by screws, and an electric heating plate 501 is provided on the inner wall of the heating frame 5. The XPE foam sheet is preheated by the electric heating plate 501 to make it easier to be thinned, thereby improving the thinning efficiency and helping to maintain the flatness of the sheet.

[0024] The cooling assembly 6 includes a fan bracket 601, which is connected to the support frame 1 by screws. A plurality of cooling fans 602 are installed inside the fan bracket 601. The cooling fans 602 are used to quickly cool the thinned sheet to prevent it from being deformed or damaged due to high temperature, thereby helping to maintain the stability and durability of the sheet.

[0025] The slider 205 is connected to the screw motor 204 through the screw lifting, and the slider 205 is slidably connected to the mounting frame 203. The slider 205 cooperates with the screw motor 204 to achieve precise lifting and lowering adjustment, thereby controlling the pressure size and the thinning thickness of the thinning mechanism.

[0026] An oblique conveying pipe 301 is fixedly provided at the bottom of the residual material tray 3, and the residual material tray 3 is connected to the support frame 1 by screws.

[0027] A motor 7 is provided at the lower part of the support frame 1 and connected by screws. The output end of the motor 7 is connected to one end of the second rolling roller 202 through a transmission structure, and the transmission structure is one of a chain drive, a belt drive, and a transmission shaft.

[0028] The mounting frame 203 is connected to the support frame 1 via screws, and the mounting frame 203 is connected to the second laminating roller 202 via a rotating shaft.

[0029] Working principle: During the use of the present invention, the XPE foamed sheet enters the thinning mechanism 2 smoothly and continuously through the feeding roller 4. Before entering the thinning mechanism 2, the sheet first passes through the heating frame 5. The electric heating plate 501 in the heating frame 5 preheats the sheet to soften it and make it easier to be thinned. The preheated sheet enters the thinning mechanism 2, and the screw motor 204 drives the slider 205 to rise and fall, thereby adjusting the gap between the first rolling roller 201 and the second rolling roller 202, thereby controlling the thinning thickness. The motor 7 drives the second rolling roller 202 to rotate, and drives the first rolling roller 201 to rotate through a transmission structure (such as a chain drive, a belt drive or a transmission shaft), and the two together perform thinning on the sheet;

[0030] During the thinning process, excess sheets or waste materials are collected in the residual material tray 3 and slide to the designated position through the inclined conveying pipe 301. The thinned sheets enter the cooling assembly 6 for rapid cooling, which helps to improve the stability and durability of the sheets. The cooled and shaped sheets are conveyed to the outlet of the equipment.
