[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides an embossing roller for paper product production, comprising an inner cylinder 1 and an embossing cylinder, wherein a fixing block 1 3 is fixed to one end of the inner cylinder 1, and a fixing block 2 4 is fixed to the other end of the inner cylinder 1. The setting of the fixing block 1 3 and the fixing block 2 4 facilitates the fixing of the inner cylinder 1, the outer surface of the inner cylinder 1 is fixedly connected with the fixing cylinder 2, and the outer diameter of the end of the fixing block 1 3 connected to the inner cylinder 1 is the same as the outer diameter of the fixing cylinder 2, and the outer diameter of the end of the fixing block 2 4 connected to the inner cylinder 1 is the same as the outer diameter of the inner cylinder 1. By setting the size of the fixing block 1 3 and the fixing block 2 4, the embossing cylinder to be replaced is replaced from one end of the inner cylinder 1, so that when the embossing cylinder is replaced, the inner cylinder 1 does not need to be disassembled, thereby improving the convenience of replacing the embossing cylinder.

[0028] The outer surface of the fixed cylinder 2 is provided with scale lines, and the setting of the scale lines facilitates the staff to adjust the position of the embossing cylinder on the inner cylinder 1, thereby improving the accuracy of the fixed position of the embossing cylinder.

[0029] A heating plate 11 is evenly fixedly connected in the inner cavity of the inner cylinder 1, and an electric heating rod 12 is fixedly connected in the middle of the inner cavity of the heating plate 11. The inner cavity of the heating plate 11 is filled with a heating liquid, such as water. A control switch 13 is fixed on one side of the heating plate 11, and the electric heating rod 12 is electrically connected to the control switch 13. When the embossing roller is in use, the staff can control the on and off of the electric heating rod 12 through the control switch 13, so that when the embossing roller is in use, the heating plate 11 located outside the embossing cylinder does not need to work, which can save the power of the embossing roller when in use.

[0030] In some embodiments of the present application, the control switch 13 is a push switch, and through holes 14 are evenly arranged on the side wall of the inner cylinder 1, and the control switch 13 is located in the inner cavity of the through holes 14. The through holes 14 are arranged to facilitate the staff to press the control switch 13, and before the embossing cylinder is installed, the staff can accurately adjust the opening and closing of the control switch 13 through the scale line, which is convenient for the use of the embossing roller.

[0031] The above-mentioned embossing cylinder includes a heat transfer cylinder 6 and an embossing cylinder body 5. The inner diameter of the heat transfer cylinder 6 is adapted to the outer diameter of the inner cylinder 1, and the outer diameter of the heat transfer cylinder 6 is adapted to the inner diameter of the fixed cylinder 2. When the embossing cylinder is installed, the heat transfer cylinder 6 is located between the inner cylinder 1 and the fixed cylinder 2. By using the heat transfer cylinder 6, the heat generated by the heating plate 11 during operation can be transferred to the embossing cylinder body 5.

[0032] The outer surface of the heat transfer tube 6 is fixedly connected to the embossing tube body 5, the end of the embossing tube body 5 is fixedly connected to the fixing sleeve 7, the middle of the fixing sleeve 7 is movably connected to the double-headed screw 8, the top of the fixing sleeve 7 is flush with the top of the double-headed screw 8, and the distance between the top of the fixing sleeve 7 and the inner wall of the heat transfer tube 6 is smaller than the distance between the inner wall of the heat transfer tube 6 and the outer wall of the embossing tube body 5. It can be seen from the above description that the fixing sleeve 7 will not affect the embossing tube.

[0033] The outer circle thread at one end of the double-headed screw 8 is connected to the upper pressing plate 10, and the outer circle thread at the other end of the double-headed screw 8 is connected to the lower pressing plate 9. Both the upper pressing plate 10 and the lower pressing plate 9 are in contact with the end of the embossing cylinder body 5. The embossing cylinder body 5 can limit the upper pressing plate 10 and the lower pressing plate 9 so that the upper pressing plate 10 and the lower pressing plate 9 can only move in the direction where the double-headed screw 8 is located, and the upper pressing plate 10 and the lower pressing plate 9 have different moving directions. The inner diameter of the upper pressing plate 10 is the same as the outer diameter of the fixed cylinder 2, and the outer diameter of the lower pressing plate 9 is the same as the inner diameter of the fixed cylinder 2.

[0034] From the above description, it can be seen that the rotation of the double-headed screw 8 can change the positions of the upper pressure plate 10 and the lower pressure plate 9. The upper pressure plate 10 can fit tightly with the outer wall of the fixed cylinder 2, and the lower pressure plate 9 can fit with the inner wall of the fixed cylinder 2, thereby realizing the fixation of the embossing cylinder.

[0035] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0036] To sum up: when the embossing roller for paper product production is in use, the electric heating rod 12 located in the inner cavity of the embossing cylinder is in a powered state. The heat generated by the electric heating rod 12 when working is transferred to the liquid around it. The heat in the liquid is transferred to the embossing cylinder body 5 through the cylinder wall of the inner cylinder 1, the heat transfer cylinder 6 and the fixed cylinder 2. When the embossing cylinder body 5 embosses paper products, the embossing can be heated for shaping the embossing. If the embossing cylinder body 5 needs to be replaced, the staff rotates the double-headed screw 8. The rotation of the double-headed screw 8 makes the upper pressure plate 10 and the lower pressure plate 9 threadedly connected thereto move away from each other until the upper pressure plate 10 and the lower pressure plate 9 are separated from the fixed cylinder 2, thereby releasing the fixation of the embossing cylinder. The staff translates the embossing cylinder to achieve the removal of the embossing cylinder. The staff puts the replaced embossing cylinder on the outside of the inner cylinder 1, and after moving the replaced embossing cylinder to a suitable position of the inner cylinder 1, the staff rotates the double-headed screw 8 and uses the upper pressure plate 10 and the lower pressure plate 9 to fix the embossing cylinder and the fixed cylinder 2 together. After removing the old embossing cylinder, the staff can adjust the on and off of the electric heating rod 12 according to the fixed position of the replaced embossing cylinder.

[0037] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
