Embodiment 1

[0029] refer to Figure 1-4 , an embossing device for PVC tablecloth processing, comprising a fixed frame 1, two embossing rollers 2 are rotatably connected to the middle position between the inner walls at both ends of the fixed frame 1, and the embossing rollers 2 are located between the inner walls at both ends of the fixed frame 1 Two limit rollers 3 are rotatably connected on both sides of the fixed frame 1, and the position corresponding to the limit roller 3 on the inner wall of the two ends of the fixed frame 1 is provided with a limit groove 4 arranged obliquely, and the top of the limit groove 4 is far away from the embossing roller. One side of 2 is inclined, the inner wall of the limiting groove 4 is slidingly connected to the limiting block, and the end of the limiting roller 3 is connected to the limiting block in rotation, and a limiting rod is fixed between the top and bottom inner walls of the limiting groove 4 5, and the middle position of the top of the limi...

Embodiment 2

[0035] refer to Figure 5-6 , an embossing device for PVC tablecloth processing, two airflow parts 15 are fixed on the side of the embossing roller 2 away from the auxiliary box 11 between the inner walls of the two ends of the fixed frame 1, and the inside of the airflow part 15 is hollow. The opposite outer walls of the air flow parts 15 are fixed with a plurality of ventilation pipes 16, and the opposite outer walls of the two air flow parts 15 are provided with a plurality of ventilation holes 17, and the opposite outer walls of the two air flow parts 15 are all arranged as an outwardly arched arc surface structure.

[0036] When in use, use the ventilation pipe 16 on the top of the airflow part 15 and the ventilation hole 17 at the bottom to carry out the blowing operation on the surface of the PVC base layer, and use the arc surface at the bottom of the airflow part 15 to ensure the effect of uniform heat dissipation on the surface of the PVC base layer, and through the ...

Abstract

The invention belongs to the technical field of polyvinyl chloride (PVC) tablecloth processing, in particular to an embossing device for PVC tablecloth processing. Aiming at the problem of a poor embossing effect on a PVC base layer in the prior art, the invention provides the following scheme that the embossing device for PVC tablecloth processing comprises a fixed frame, wherein two embossing rollers are rotatably connected in the middle position between the inner walls of two ends of the fixed frame; two limiting rollers are rotatably connected to the positions, located on two sides of theembossing rollers, between the inner walls of two ends of the fixed frame; inclinedly arranged limiting grooves are formed in the positions, corresponding to the limiting rollers, on the inner walls of two ends of the fixed frame; the top ends of the limiting grooves are inclined toward one sides far away from the embossing rollers; and limiting blocks are slidably connected to the inner walls ofthe limiting grooves. According to the embossing device for PVC tablecloth processing provided by the invention, by utilizing first springs, the shrinkage or elongation of the PVC base layer in the horizontal direction during embossing operation can be reduced; and by utilizing protruding pieces spirally distributed on the outer walls of the limiting rollers, the friction force between the limiting rollers and the PVC base layer in the horizontal direction is improved, so that an embossing error is reduced, and an actual embossing effect of the PVC base layer is improved.

Description

technical field [0001] The invention relates to the technical field of PVC tablecloth processing, in particular to an embossing device for PVC tablecloth processing. Background technique [0002] Tablecloths are items that are covered on tables and desktops to prevent pollution or increase aesthetics. Because they are habitually covered on tables, they are also called tablecloths. Tablecloths are divided into plastics and textiles according to their production processes. PVC tablecloth is a common type of plastic tablecloth. [0003] In the process of production and processing of PVC tablecloth, PVC base layer and printing film are generally prepared. After embossing and laminating the PVC base layer, the finished PVC tablecloth is obtained. Now in the process of embossing the PVC base layer Generally, the conveying roller is used to send the PVC base layer between the two embossing rollers, and the texture of the outer wall of the two embossing rollers is used to emboss th...
