Description

Technical Field

[0001] This utility model relates to the field of EVA sheet processing technology, specifically an embossing machine that facilitates the winding of EVA sheets. Background Technology

[0002] EVA sheet is a sheet made of ethylene-vinyl acetate copolymer. It has the characteristics of good flexibility, chemical corrosion resistance and excellent insulation, and is widely used in packaging, building materials, electronics and other fields.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN217849877U) discloses an embossing machine for facilitating the winding of EVA sheets. The machine includes a base, on which a transmission roller and an embossing roller driven by two motors are mounted. It also includes a rotating roller, which is mounted on the base and located on the side of the embossing roller away from the transmission roller. The rotating roller is connected to the output shaft of a first motor mounted on the base. A hollow tube is fitted onto the rotating roller, and the hollow tube has two openings, the width of which is the same as the width of the EVA sheet. One end of the EVA sheet passes through the transmission roller and the embossing roller, enters the hollow tube through one opening, and exits through the other opening.

[0004] Although the aforementioned patent provides an embossing machine that can fix and wind EVA sheets, with dual-motor driven transmission rollers working in conjunction with embossing rollers to stably transport EVA sheets and efficiently complete the embossing process, and two openings matching the width of the EVA sheets to guide and wind the embossed sheets in an orderly manner, the equipment lacks a cleaning structure. When the EVA sheets pass through components such as the transmission rollers and embossing rollers, the surface of the EVA sheets is easily contaminated with dust, impurities, or debris remaining on the rollers. These contaminants will enter the embossing process with the sheets, causing defects in the embossed pattern, or scratches and foreign object indentations on the sheet surface, reducing the appearance and performance of the product. Impurities may also be trapped between the rollers and the sheets, causing wear on the surfaces of the transmission rollers and embossing rollers as the rollers rotate and rub against the roller surfaces repeatedly.

[0005] Therefore, this utility model provides an embossing machine that facilitates the winding of EVA sheets to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides an embossing machine that facilitates the winding of EVA sheets, such as... Figure 1 - Figure 5 As shown, the device includes a placement platform 1, a collection box 12 installed below the placement platform 1, a fan 15 installed behind the collection box 12, a filter screen 14 installed inside the collection box 12, a third mounting plate 8 installed on the upper surface of the placement platform 1, a first hollow tube 9 installed inside the third mounting plate 8, a first dust suction port 31 opened on the outside of the first hollow tube 9, one end of the first hollow tube 9 being connected to the collection box 12, a lifting rod 10 installed on the right side of the third mounting plate 8, a second hollow tube 11 installed inside the lifting rod 10, a second dust suction port 32 opened on the outside of the second hollow tube 11, one end of the second hollow tube 11 being connected to the collection box 12.

[0029] The core dust collection and filtration structure consists of a collection box 12, a fan 15, and a filter 14. Combined with the zoned dust collection design of the first hollow tube 9 and the first suction port 31, and the second hollow tube 11 and the second suction port 32, a closed loop for impurity cleaning is formed from embossing to rewinding. The first hollow tube 9 removes debris and dust generated during embossing at close range. The second hollow tube 11, with the height adjustment function of the lifting rod 10, is adapted to sheets of different thicknesses and performs a second cleaning of residual impurities on the surface before rewinding. This dual protection effectively reduces impurity adhesion and significantly improves the embossing quality and surface cleanliness of the EVA sheet. The collection box 12 and the filter 14 achieve centralized collection and filtration of impurities, preventing dust diffusion and environmental pollution. This maintains a clean working environment and facilitates subsequent unified processing of impurities, reducing manual cleaning costs.

[0030] The upper surface of the placement platform 1 is equipped with a first mounting plate 2, a first motor 5 is mounted in front of the first mounting plate 2, a drive transmission roller 3 and a driven transmission roller 4 are mounted on the inner side of the first mounting plate 2 respectively, the output end of the first motor 5 is connected to the drive transmission roller 3, and the driven transmission roller 4 is located above the drive transmission roller 3. The upper surface of the placement platform 1 is equipped with a second mounting plate 6, a heating roller 7 is mounted inside the second mounting plate 6, the upper surface of the placement platform 1 is equipped with a first support plate 17, a second motor 20 is mounted in front of the first support plate 17, a drive embossing roller 18 and a driven embossing roller 19 are mounted on the inner side of the first support plate 17 respectively, the output end of the second motor 20 is connected to the drive embossing roller 18, and the driven embossing roller 19 is located above the drive embossing roller 18.

[0031] The first motor 5 drives the transmission roller 3 to rotate, forming a clamping and conveying structure with the driven transmission roller 4, which can smoothly convey the EVA sheet. The heating roller 7 in the second mounting plate 6 can heat and soften the conveyed EVA sheet, making the sheet easier to shape. The second motor 20 drives the embossing roller 18 to rotate, which works with the driven embossing roller 19 to perform embossing operation on the sheet. The motor drive ensures stable embossing force and speed. From the conveying of the drive transmission roller 3 and the driven transmission roller 4, to the pretreatment of the heating roller 7, and then to the embossing of the drive embossing roller 18 and the driven embossing roller 19, the components cooperate in an orderly manner under the support of the first mounting plate 2, the second mounting plate 6, and the first support plate 17, to build a continuous EVA sheet processing line, reduce the process connection time, and improve the overall production efficiency.

[0032] The upper surface of the placement platform 1 is equipped with a second support plate 21, a third motor 23 is installed in front of the second support plate 21, an auxiliary roller 22 is installed on the inner side of the second support plate 21, the output end of the third motor 23 is connected to the auxiliary roller 22, a fourth motor 25 is installed in front of the second support plate 21, a take-up roller 24 is provided on the inner side of the second support plate 21, bearing bases 26 are installed at both ends of the take-up roller 24, locking parts 27 are installed on the outer surface of the bearing bases 26, the two bearing bases 26 are connected to the second support plate 21 together, and the output end of the fourth motor 25 is connected to the take-up roller 24.

The pull-out door 16 is slidably connected to the sliding groove 13. The third motor 23 drives the auxiliary roller 22 to rotate, which can provide stable conveying force when the sheet transitions from the embossing stage to the winding stage. The fourth motor 25 drives the winding roller 24 to rotate, which can automatically complete the embossing process. The EVA sheet winding process replaces manual winding, reducing labor costs. The locking component 27 can stop and resume the winding roller 24 in a timely manner. The four support legs 29 provide stable support for the placement platform 1. The support feet 30 increase the contact area with the ground, reducing displacement caused by vibration during equipment operation.
