Abstract
Description
Technical Field
[0001] The utility model relates to the field of napkin production, in particular to a detachable folding block structure. Background Art
[0002] The folding block is used on the folding roller of the napkin automatic production line folding machine. In the prior art, the folding block and the folding roller of the folding machine are integrated. When the folding roller runs for a long time, the folding block will be worn, causing the end surface of the folding block to be uneven and arc-shaped, making it difficult to clamp the napkin paper or the paper clamping is unstable, and the entire folding roller needs to be replaced. The folding roller has a complex structure, and it requires multiple technicians to cooperate with each other to complete the replacement, which takes a long time and is costly.
[0003] Therefore, it is necessary to develop a detachable folding block structure for easy operation. Utility Model Content
[0004] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides a detachable folding block structure, in which the folding roller and the folding block are separated and designed independently, and fixed with hexagon socket bolts; when the folding block is worn, it is only necessary to remove the hexagon socket bolts and replace the new folding block, without replacing the entire folding roller, which is easy to operate and use.
[0005] Technical solution: The utility model is a detachable folding block structure, characterized in that it includes a detachable folding block, the detachable folding block is connected to the folding roller through a concave and convex groove, the detachable folding block and the folding roller are provided with corresponding bolt holes, and the detachable folding block and the folding roller are connected by hexagon socket bolts passing through the corresponding bolt holes; the circumference of the folding roller is 460mm-840mm, and the radius is 73.2mm-133.8mm.
[0006] Wherein, the concave-convex groove includes a convex portion located on the detachable folding block and a concave portion located on the folding roller.
[0007] Among them, the number of the detachable folding blocks is 2; the hexagon socket bolts are M8 hexagon socket bolts.
[0008] Wherein, the detachable folding block is provided with two countersunk holes, and the two countersunk holes are horizontal.
[0009] Wherein, the circumference of the folding roller is 460 mm and the radius is 73.2 mm.
[0010] Wherein, the circumference of the folding roller is 550 mm and the radius is 87.6 mm.
[0011] Wherein, the circumference of the folding roller is 650 mm and the radius is 103.5 mm.
[0012] Wherein, the circumference of the folding roller is 840 mm and the radius is 133.8 mm.
[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model separates the folding roller and the folding block into independent designs and fixes them with hexagon socket bolts; when the folding block is worn, only the hexagon socket bolts need to be removed and replaced with a new folding block, without replacing the entire folding roller, which is convenient for operation and use. Quick replacement of wearing parts reduces replacement time and improves efficiency; reduces material consumption costs, and changes from replacing the folding roller to replacing the folding block.

[0015] Figure 2 It is a structural schematic diagram of the utility model;
[0016] Figure 3 This is a schematic diagram of the structure of the detachable folding block of the utility model;
[0017] In the figure, 1 is a detachable folding block; 2 is a hexagon socket bolt; 3 is a concave-convex slot; and 4 is a folding roller. DETAILED DESCRIPTION
[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0019] The detachable folding block structure of the utility model comprises a detachable folding block 1, which is connected to a folding roller 4 via a concave-convex groove 3, and the detachable folding block 1 and the folding roller 4 are provided with corresponding bolt holes, and the detachable folding block 1 and the folding roller 4 are connected via a hexagon socket bolt 2 passing through the corresponding bolt hole; the circumference of the folding roller 4 is 460mm-840mm, and the radius is 73.2mm-133.8mm. Among them, the concave-convex groove 3 includes a convex portion located on the detachable folding block 1 and a concave portion located on the folding roller 4. The number of detachable folding blocks 1 is 2; the hexagon socket bolt 2 is an M8 hexagon socket bolt. Two countersunk holes are provided on the detachable folding block 1, and the two countersunk holes are horizontal.
[0020] According to specific needs, the folding roller 4 is commonly used in four sizes, namely:
[0021] Dimension 1: The circumference of the folding roller 4 is 460 mm and the radius is 73.2 mm.
[0022] Dimension 2: The circumference of the folding roller 4 is 550 mm and the radius is 87.6 mm.
[0023] Dimension three: The circumference of the folding roller 4 is 650 mm and the radius is 103.5 mm.
[0024] Dimension 4: The circumference of the folding roller 4 is 840 mm and the radius is 133.8 mm.
[0025] Taking size 1 as an example, the circumference of the folding roller 4 is 460 mm and the radius is 73.2 mm. The size of the detachable folding block 1 is 44 mm*46.2 mm. The inside of the detachable folding block 1 is a vertical and arc structure, and the inside of the detachable folding block 1 is a vertical and oblique structure, and the angle between the oblique part and the vertical part is 120°.
[0026] The utility model separates the folding block and the folding roller so that the folding block is independently designed to be detachable. In order to prevent the installation position from shifting, the connection between the folding block and the folding roller adopts a concave-convex card groove so that they can be fixed together more tightly and have higher load-bearing capacity and stability.
[0027] The utility model opens two countersunk holes on the folding block, the two holes are horizontal, opens holes on the corresponding folding rollers and taps the threads to M8, and fixes the folding block to the folding rollers with two M8 hexagon socket bolts. The material of the folding block is adjusted from ordinary carbon structural steel to copper alloy, which has higher wear resistance and prolongs the service life of the folding block.
