Description

Technical Field

[0001] The utility model relates to the field of paper towel embossing machines, and more specifically, to a paper towel embossing machine. Background Art

[0002] As a necessity in daily life, the appearance and touch of paper towels are crucial to consumers. In the production process of paper towels, an embossing machine is needed to emboss the paper towels. As an important equipment in the production process of paper towels, the embossing machine mainly places the paper towels to be embossed on a conveying device for conveying. When the paper towels are conveyed to the embossing roller, the embossing process can be carried out. When the paper towels are embossed on the embossing machine, due to different production needs, the sizes of the paper towels are also different. In addition, due to the softness and deformability of the paper towel material, the paper towels may be offset and uneven when being conveyed on the conveying device, resulting in incorrect printing position, resulting in poor embossing effect on the paper towels and increased waste generation, reducing the work efficiency of printing. At the same time, the waste generation will cause economic losses.

[0017] Reference Figures 1 to 3 The utility model is further described in detail.

[0018] A paper towel embossing machine comprises a conveyor 1 for conveying paper towels and an embossing mechanism for embossing on paper towels in cooperation with the conveyor 1, wherein the embossing mechanism comprises a mounting frame 2, a second motor 3 and an embossing roller 4, wherein the mounting frame 2 is fixed on the conveyor 1, the second motor 3 is fixed on the mounting frame 2, the embossing roller 4 is fixedly connected to the shaft of the second motor 3, and the embossing roller 4 cooperates with a conveyor belt on the conveyor 1.

[0019] The conveyor 1 is provided with a positioning assembly corresponding to the embossing roller 4. The positioning assembly can be set to position a number of paper towels at different positions on the conveyor 1. The positioning assembly includes two fixed plates 5 respectively installed on both sides of the conveyor 1 and a positioning roller 6 placed between the two fixed plates 5 and corresponding to the conveyor 1. A first motor 7 cooperating with the positioning roller 6 is installed on one fixed plate 5. A bearing is passed through the fixed plate 5. The shaft of the first motor 7 passes through the corresponding fixed plate 5 through the bearing and is rotatably connected to the corresponding fixed plate 5. The shaft of the first motor 7 is fixedly connected to one end of the positioning roller 6. Another bearing is installed at the other end of the positioning roller 6. The other end of the positioning roller 6 is rotatably connected to another fixed plate 5 through this bearing. The upper sliding drive of the positioning roller 6 is connected to a number of evenly arranged fixed rollers. A positioning ring 8 is provided with a plurality of connecting holes 11, and the positioning ring 8 is provided with a plurality of screws 12 which are respectively threadedly connected with the plurality of connecting holes 11, and the screws 12 are in contact with the positioning roller 6, and the screws 12 include a contact surface which cooperates with the arc surface of the positioning roller 6, and a rubber pad 14 which cooperates with the positioning roller 6 is fixed on the contact surface, and the screws 12 are rotated to make the rubber pad 14 on the screws 12 in contact with the positioning roller 6, and the positioning ring 8 is provided with a plurality of elastic blocks 9 which surround the positioning ring 8 and a plurality of positioning plates 10 which correspond to the plurality of elastic blocks 9 one by one, and the two ends of the elastic blocks 9 are respectively fixedly connected with the positioning ring 8 and the corresponding positioning plates 10, and the plurality of positioning plates 10 cooperate with each other to form a pressing cylinder which cooperates with the conveyor belt on the conveyor 1, and the positioning plates 10 are arc-shaped, and the cross-section of the elastic blocks 9 is trapezoidal.

[0020] Working principle: According to the size of the embossed paper towel, adjust the position of the positioning ring 8 on the positioning roller 6. Specifically, rotate the screw 12 in the connecting hole 11 on the positioning ring 8 so that the screw 12 does not contact the positioning roller 6, and then slide the positioning ring 8 to the corresponding position on the positioning roller 6 to facilitate the mutual cooperation of several positioning rings 8. Then rotate the screw 12 to make the rubber pad 14 on the contact surface of the screw 12 contact with the surface of the positioning roller 6. The contact surface cooperates with the arc surface of the positioning roller 6 to facilitate better contact between the screw 12 and the positioning roller 6. The setting of the rubber pad 14 on the contact surface increases the friction between the screw 12 and the positioning roller 6, so that the positioning ring 8 is more stably fixed at this position of the positioning roller 6. The plurality of positioning plates 10 on the positioning ring 8 cooperate to form a positioning cylinder 13 that cooperates with the conveyor belt on the conveyor 1, so that the plurality of positioning cylinders 13 cooperate with each other. The conveyor 1 works to convey the paper towel to be embossed to the positioning roller 6. The first motor 7 works to drive the positioning roller 6 to rotate, thereby rotating the plurality of positioning rings 8 on the positioning roller 6, and then driving the plurality of positioning plates 10 on the positioning ring 8 to rotate. The elastic block 9 is deformed so that the positioning block will contact the paper towel on the conveyor belt of the conveyor 1, so as to achieve the positioning of the paper towel to be embossed. The positioning plate 10 is arc-shaped and the cross-section of the elastic block 9 is trapezoidal, which is convenient for better contact with the paper towel and does not damage the surface of the paper towel. The positioning plates 10 on the positioning ring 8 cooperate with each other, and the corresponding positioning plates 10 on several positioning rings 8 contact different positions in the width direction of the paper towel on the conveyor 1, further improving the positioning effect, and adjusting the spacing between two adjacent positioning rings 8 facilitates the positioning plates 10 on the positioning ring 8 to position paper towels of different sizes, thereby avoiding the deviation of paper towels of different sizes during the conveying process, and the positioning cylinders 13 formed by the cooperation of several positioning plates 10 rotate with the rotation of the positioning roller 6 and rotate on the surface of the paper towel, and cooperate with the conveyor belt of the conveyor 1 to flatten the paper towel to be embossed before embossing, and the positioning cylinders 13 on several positioning rings 8 cooperate with each other to further improve the flattening effect, thereby improving the subsequent embossing Quality, and then the paper towel to be embossed is conveyed to the embossing roller 4 through the conveyor 1, and the embossing roller 4 is driven by the second motor 3 to rotate to emboss the passing paper towel, and the paper towel is pressed against the conveyor belt of the conveyor 1 through a plurality of positioning cylinders 13 at the positioning roller 6 to avoid the paper towel from shifting when embossing at the embossing roller 4, thereby improving the positioning effect and facilitating the embossing mechanism to complete the embossing work, so that the embossing machine can position the produced paper towels of different sizes, improve the positioning effect of paper towels of different sizes during the transmission process, and flatten the paper towel to improve practicality, avoid the paper towel from shifting and being uneven, resulting in inaccurate printing position and poor printing effect, and reduce the printing work efficiency.
