Description

Technical Field

[0001] The utility model relates to paper product production equipment, in particular to a heating embossing mechanism which uses a heated embossing roller to emboss patterns on multi-layer paper and heats the paper at the same time. Background Art

[0002] Some paper product production equipment is equipped with a heated embossing mechanism. This type of mechanism uses a heated embossing roller to emboss the pattern on the paper while heating the paper, so that the paper becomes fluffy and easier to use (for example, fluffy kitchen paper can absorb more moisture or oil stains), or when glue is used to bond multiple layers of paper, it can make the glue dry quickly and accelerate the adhesive bonding between paper layers. In the prior art, this type of heated embossing mechanism uses high-temperature oil, steam or water circulation system to heat the embossing roller, which poses the risk of hot oil ignition, high-pressure and high-temperature fluid leakage, etc., and requires a fluid channel to be set in the embossing roller, which has a complex structure and is difficult to maintain. Utility Model Content

[0003] The purpose of the utility model is to provide a heating embossing mechanism to eliminate the dangers existing in the above-mentioned prior art.

[0004] The utility model is implemented as follows: a heating embossing mechanism comprises an embossing roller with a convex pattern on the roller surface, in particular, an electric heating element is arranged near the embossing roller, the electric heating element has no contact with the embossing roller, and the electric heating element heats the embossing roller in a heat radiation manner.

[0005] As a best implementation, the electric heating element is bent or arranged into an arc shape, and the concave-convex direction of the arc shape is consistent with the concave-convex direction of the embossing roller surface it is close to.

[0006] As a best embodiment, the portion of the embossing roller close to the electric heating element is a portion of the roller surface that is not covered by paper.

[0007] The utility model has the advantages that there is no danger of hot oil ignition, high-pressure and high-temperature fluid leakage, etc., and the system using electric heating elements is easier to control temperature than high-temperature oil, steam or water circulation systems, has a simpler structure, and is easier to maintain.

[0011] To facilitate understanding of the present invention, a more comprehensive description is given below in conjunction with the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0012] See also Figure 1 The heating embossing mechanism of this embodiment includes two embossing rollers 1, and the roller surfaces of the two embossing rollers 1 are provided with raised patterns. The two embossing rollers 1 are respectively against a rubber roller 2. When two sheets of paper 3 from different sources pass between the embossing rollers 1 and the rubber roller 2, the two embossing rollers 1 emboss patterns on the two sheets of paper 3 respectively, and finally the two sheets of paper are pressed together by a plain roller 4 without patterns against one of the embossing rollers 1.

[0013] Two electric heating elements 5 are provided near the two embossing rollers 1. The electric heating elements 5 are not in contact with the embossing rollers 1. The electric heating elements 5 heat the embossing rollers 1 near them by heat radiation, so that the paper passing through the embossing rollers 1 is heated. In this embodiment, a temperature sensor 6 is also provided to monitor the temperature of the two embossing rollers 1 in real time. The temperature sensor 6 is provided at a position covered by the paper near the two embossing rollers 1 at the same time, so as to simultaneously sense the temperature of the two pieces of paper covered on the two embossing rollers.

[0014] As the best implementation, the electric heating element 5 of this embodiment is bent into an arc shape, and the concave and convex direction of the arc shape is consistent with the concave and convex direction of the embossing roller surface it is close to, so that the distances between various parts of the electric heating element 5 and the roller surface of the embossing roller 1 are equal or nearly equal, thereby improving the heating efficiency. The electric heating element 5 can be a commercially available Figure 2 A bendable finished heating plate is shown.

[0015] As another embodiment, Figure 3 As shown, multiple electric heating elements 5 are arranged into an arc shape shown by a dotted line, and the concave and convex direction of the arc shape is consistent with the concave and convex direction of the roller surface of the embossing roller 1 to which it is close. This embodiment is more suitable for inflexible electric heating elements, such as graphene electric heating tubes and quartz electric heating tubes, so that the distances between each electric heating element and the roller surface of the embossing roller are equal or nearly equal.

[0016] As the best implementation, Figure 1 As shown, the portion of the embossing roller 1 close to the electric heating element 5 is a portion of the roller surface not covered by paper material, so as to prevent the paper material from being heated and ignited by the electric heating element.

[0017] It should be noted that Figure 1This is just one embodiment, and different paper product production equipment may have different settings. For example, some paper product production equipment has only one embossing roller, some may have more than two embossing rollers, and some equipment also has a gluing mechanism for applying glue to the paper material. These equipment can all adopt the heating embossing mechanism described in the utility model.

[0018] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of protection of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these modifications and improvements all belong to the scope of protection of the utility model.
