Embodiment

[0019] A symmetrical side embossing wheel pressing device, its structure is as follows figure 1 As shown, the device includes a side embossing wheel shaft 1, a shaft retaining ring 2, a side embossing wheel 3, a depressing guide post 4, and a pin shaft 5.

[0020] Side embossing wheel shafts 1 are arranged on both sides of the lower part of the depressing guide post 4, and the side embossing wheel shafts 1 are connected to the pressing down guide posts through pin shafts 5, and side embossing wheels 3 are sheathed on the side embossing wheel shafts 1. , the warp shaft is fixed on the side embossing wheel shaft 1 with the spring retaining ring 2, so that the side embossing wheel 3 is symmetrically arranged on both sides of the depressing guide post 4, and evenly distributes the pressure generated when the depressing guide post 4 is pressed down.

[0021] Working principle: Install two side embossing wheels 3 face-to-face symmetrically on both ends of the side embossing wheel sh...

Abstract

The invention relates to a symmetric edge-knurling roller hold-down device comprising a hold-down guide post (4) and two edge-knurling rollers (3) symmetrically disposed on two sides of the hold-down guide post (4). Pressure generated when the hold-down guide post (4) holds down is evenly distributed by the edge-knurling rollers (3). Compared to the prior art, the symmetric edge-knurling roller hold-down device has the advantages that the problem of uneven knurling depths of one side and the other side during edge knurling is solved, the service life of the device is prolonged, and the cost of using the device is reduced.

Description

technical field [0001] The invention relates to an embossing device, in particular to a symmetrical edge embossing wheel depressing device. Background technique [0002] In order to meet the requirements of consumers, the existing facial tissue processing machines mostly use edge embossing devices to ensure that the facial tissue products are not delaminated. However, the pressing device of the side embossing wheel of the facial tissue machine adopts an asymmetric structure design. During the production process, one side embossing is deep and the other side is shallow. The analysis reason is caused by the imbalance between the pressing force and the reaction force. The most important thing is the eccentric force. The side of the side embossing wheel under high pressure is easy to wear, and the side under small pressure is not easy to wear. Therefore, after a period of production, the embossing wheels on both sides wear differently, and the product quality cannot be guarantee...
