Description

Technical Field

[0001] This utility model relates to the field of EVA pad processing technology, specifically to an EVA pad surface texture embossing machine. Background Technology

[0002] EVA padding refers to padding material made of ethylene-vinyl acetate copolymer. EVA padding has many excellent properties and a wide range of applications. When embossing the surface texture of EVA padding, an EVA pad surface texture embossing machine is required. The EVA pad surface texture embossing machine uses upper and lower texture rollers to rotate and emboss.

[0003] In the embossing machine for EVA pads, the upper embossing roller is raised and lowered by a lifting device to meet the embossing needs of EVA pads of different thicknesses. When embossing EVA pads for gifts, the outer side lacks a conveying limit structure and a positioning conveying structure, which can easily cause the embossing of EVA pads to deviate during the embossing process.

[0004] Therefore, we propose a novel EVA pad surface texture embossing machine to solve the above-mentioned technical problems. Utility Model Content

Figures 1-6 As shown, it includes the surface texture embossing machine body, a four-hole mounting base plate 11, a conveying and limiting mechanism, a rolling positioning mechanism, and an EVA pad workpiece 5.

[0035] The four-hole mounting base plate 11 is fixed to the lower end of the surface texture embossing machine body. The surface texture embossing machine body can be installed in the designated position by screws through the four-hole mounting base plate 11 at the lower end.

The conveying limiting mechanism on both sides of the front end of the surface texture embossing machine body can effectively clamp and limit. The rolling positioning mechanism is installed and connected to the upper side of the inner end of the conveying limiting mechanism. The rolling positioning mechanism can roll and press down on the conveying limiting mechanism for positioning. The EVA pad workpiece 5 is located between the two conveying limiting mechanisms. The EVA pad workpiece 5 can be effectively limited in position and conveyed by the conveying limiting mechanism during feeding. Moreover, the EVA pad workpiece 5 can be effectively rolled and pressed down by the rolling positioning mechanism during conveying, so as to play a positioning role.

[0036] The surface texture embossing machine body includes an embossing body 1. A workpiece placement table 12 is fixedly connected to the front end of the embossing body 1. The EVA pad workpiece 5 can be placed on the workpiece placement table 12 for feeding. An upward lifting embossing mechanism is installed at the top inside the embossing body 1. The upward lifting embossing mechanism can change the embossing height position at the top inside the embossing body 1, so that the embossing can be adjusted according to the thickness of the EVA pad workpiece 5. A lower driven embossing roller 13 is installed in the middle of the bottom inside the embossing body 1. The lower driven embossing roller 13 can perform driven embossing in the embossing body 1. The upward lifting embossing mechanism is electrically connected to an external control box through a connecting line, so that it can be controlled by the external control box.

[0037] The lifting embossing mechanism includes a positioning sleeve 31 fixed to the top of the embossing texture machine body 1. A hollow limiting sleeve 3 is sleeved around the lower periphery of the positioning sleeve 31, allowing the hollow limiting sleeve 3 to move around the periphery of the positioning sleeve 31. A movable concave shell 41 is fixed to the lower end of the hollow limiting sleeve 3, which can move the movable concave shell 41 during positioning. Third electric telescopic cylinders 32 are installed on both sides of the hollow limiting sleeve 3 on the movable concave shell 41, with the upper ends of the third electric telescopic cylinders 32 mounted on the embossing... At the top of the interior of the texture machine body 1, the telescopic rod of the third electric telescopic cylinder 32 can drive the movable concave shell 41 to rise and fall when it extends and retracts. The upper texture embossing roller body 4 is installed on the inner side of the lower end of the movable concave shell 41. The movable concave shell 41 can drive the upper texture embossing roller body 4 installed inside to rise and fall. The right end of the upper texture embossing roller body 4 is located on the movable concave shell 41 and a roller pressing motor 42 is installed. When the output shaft of the roller pressing motor 42 rotates, it can drive the roller pressing motor 42 to rotate, so that it can actively rotate and emboss.

[0038] The output shaft of the roller press motor 42 is connected to the upper texture embossing roller body 4 through a coupling. When the output shaft of the roller press motor 42 rotates, it can drive the upper texture embossing roller body 4 to rotate and emboss through the coupling.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the rolling positioning mechanism includes a second electric telescopic cylinder 64. A telescopic cylinder mounting plate 65 is fixedly connected to the periphery of the second electric telescopic cylinder 64. The second electric telescopic cylinder 64 is mounted on the right-angle push plate 21 through the telescopic cylinder mounting plate 65, so that the second electric telescopic cylinder 64 can be installed accordingly. A connecting end column 61 is installed at the telescopic rod end of the second electric telescopic cylinder 64. When the telescopic rod of the second electric telescopic cylinder 64 is extended or retracted, it can drive the connecting end column 61 to rise or fall.

The height position of the concave housing 6 can be changed during the rising or falling of the connecting end column 61. A constant pressure roller 63 is sleeved on the inner side of the lower end of the concave housing 6. The concave housing 6 and the constant pressure roller 63 are movably connected by a connecting pin 62. The position height of the constant pressure roller 63 can be changed by the connecting pin 62, so that the overall constant pressure height can be changed, thereby adjusting the rolling positioning according to the thickness of the EVA pad workpiece 5.

[0040] In use, the surface texture embossing machine body is mounted on a four-hole mounting base plate 11 at the bottom, allowing it to be installed in the designated position using screws. The operator places the EVA padding workpiece 5 on the workpiece placement platform 12 of the surface texture embossing machine body. The EVA padding workpiece 5 is positioned between the two conveying limiting mechanisms on both sides of the upper end of the workpiece placement platform 12. The conveying limiting mechanism effectively limits the transport of the EVA padding workpiece 5 via a right-angle push plate 21. During transport, the rolling positioning mechanism at the upper end of the right-angle push plate 21 effectively rolls and positions the workpiece. The rolling positioning mechanism contacts the upper surface of the EVA padding workpiece 5 via a pressure roller 63, allowing the EVA padding workpiece 5 to be transported by the pressure roller 63 with constant pressure. This makes the transport more stable and effectively prevents the workpiece from shifting position during feeding, ensuring accurate surface texture embossing.

[0043] The conveying limiting mechanism includes a telescopic cylinder mounting base 2, which is fixedly connected to the workpiece placement platform 12 of the surface texture embossing machine body for stable placement. A first electric telescopic cylinder 22 is installed on the inner middle screw of the telescopic cylinder mounting base 2, allowing for corresponding installation. A right-angle push plate 21 is installed at the telescopic rod end of the first electric telescopic cylinder 22, allowing the position of the right-angle push plate 21 to be changed during telescopic extension and retraction. Movable sleeve plates 23 are installed at both ends of the right-angle push plate 21. The right-angle push plate 21 can drive the movable sleeve plate 23 to move. The telescopic cylinder mounting base 2 and the movable sleeve plate 23 are connected by a sleeve. The movable sleeve plate 23 can be positioned and moved in the telescopic cylinder mounting base 2, making the right-angle push plate 21 more stable when moving and changing position. Rolling positioning mechanisms are installed on both sides of the upper end of the right-angle push plate 21. The right-angle push plate 21 can change the position of the rolling positioning mechanism. The right-angle push plate 21 can effectively limit and block the EVA pad workpiece 5, so that the EVA pad workpiece 5 can be conveyed in a limited position.
