Description

Technical Field

[0002] Roll toilet paper is mainly used for people's daily hygiene and is one of the indispensable paper types for the people. Before packaging, the toilet paper needs to be cut into sections. There are many types of toilet paper cutting devices on the market, but there are still some shortcomings.

[0003] To this end, the authorized announcement is CN218285765 Chinese Utility Model, which discloses a toilet paper roll fixed-distance cutting device, including a base plate and a box body, the upper surface of the base plate and the bottom surface of the box body... The reset spring and the telescopic rod can reset the positioning plate, so that the toilet paper roll is not easy to deviate, the first hydraulic push rod can drive the fixed block to move, and the toilet paper roll is better fixed, so that it is not easy to deviate when cutting the toilet paper roll, thereby achieving a more uniform effect of cutting the toilet paper roll.

[0004] The above device has the following shortcomings: although it can handle waste paper scraps very well, the surface of the belt is smooth, which will cause insufficient conveying force during the conveying process of the toilet paper roll, resulting in the toilet paper roll being unable to be conveyed to the cutting position due to insufficient thrust, and the device only fixes one end of the toilet paper roll after cutting. If only one end is fixed and the part to be cut is not fixed, the cutting will be offset during cutting, resulting in uneven cutting.

[0005] For this reason, we propose a paper cutting device for roll-type toilet paper production to solve the above problems. Utility Model Content

The bottom parts of both ends of the transport troughs 2 are fixedly connected to the tops of a number of transport trough bases 201. The chain conveyor 1 is located between the number of transport trough bases 201. A number of power blocks 106 are located at the center line of the notch of the transport trough 2. When the servo motor 101 is started, it drives the chain plate 105 to move at a fixed distance and indirectly. The movement of the chain plate 105 drives the power block 106 to follow the movement.

[0030] Example 2

Specifically, a plurality of cutting grooves 203 are provided in parallel at one end of the plurality of transport grooves 2, and a plurality of cutting groove bases 204 are estimated to be provided at the bottom of the plurality of cutting grooves 203. The transport grooves 2 and the cutting grooves 203 are inverted trapezoids with notches in the middle, which can serve as a fulcrum when the unprocessed toilet paper roll is relaxed, and its special shape can meet the needs of toilet paper rolls of different diameters.

[0032] The tops of the piston rods of the two cylinders 3 are respectively fixedly connected to the centers of the bottoms of two connecting plates 301 , and the bottoms of four spacing plates 302 are respectively fixedly connected to the two ends of the tops of the two connecting plates 301 .

The bottoms of the two cylinders 3 are respectively fixedly connected to the tops of the two cylinder bases 305. The plurality of cutting trough bases 204 and the plurality of transport trough bases 201 are located between the two cylinder bases 305. The extension and retraction of the piston rods of the two cylinders 3 drives the two connecting plates 301 to extend and retract. The extension and retraction of the connecting plates 301 drives the four spacing plates 302 to extend and retract. The extension and retraction of the four spacing plates 302 drives the two cross bars 303 to extend and retract, thereby the plurality of U-shaped pressure plates 304 at the bottom of the two cross bars 303 follow the extension and retraction.

[0035] The tops of the two mounting frames 103 are respectively fixedly connected to the bottoms of the two linear guide rail bases 402 , and the middle parts of the top surfaces of the two linear guide rail bases 402 are respectively fixedly connected to the two ends of the linear guide rail 4 .

[0036] The top of the linear guide 4 is transmission-connected to the bottom of the slider 401, and the top of the slider 401 is fixedly connected to the bottom of the cutting motor base 502. When the linear guide 4 is started, it drives the slider 401 to move left and right on it. The movement of the slider 401 drives the cutting motor base 502 to move. The movement of the cutting motor base 502 drives the cutting motor 5 to follow the movement, so that the cutting disc 501 follows its left and right parallel movement.

Since the above is not the key point of the present invention, no further arrangement or elaboration is made.

[0039] Example 3

[0040] Reference Figure 1-7, which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, after a number of long rolls of toilet paper to be processed are placed in a number of transport slots 2, the servo motor 101 is started to drive the chain plate 105 to move at a fixed distance and indirectly. The movement of the chain plate 105 drives the power block 106 to follow the movement. As the power block 106 moves, a number of long rolls of toilet paper to be processed are pushed by the power block 106 to follow the movement on the number of transport slots 2. Further, as the movement, one end of a number of long rolls of toilet paper to be processed begins to be pushed into a number of cutting slots 203. At this time, the two cylinders 3 are started, and the piston rods of the two cylinders 3 shrink and drive the two connecting plates 301 to shrink. The shrinkage of the connecting plates 301 drives the four spacing plates 302 to shrink. The shrinkage of the four spacing plates 302 drives the two cross bars 303 to shrink, so that the several U-shaped pressing plates 304 at the bottom of the two cross bars 303 shrink and follow. As the two cylinders 3 shrink, A number of U-shaped pressure plates 304 begin to press downward to partially fix a number of long rolls of toilet paper to be processed located on a number of transport slots 2 and a number of cutting slots 203. At this time, the conditions for cutting and fixing are met, and the linear guide rail 4 is started to drive the slider 401 to move left and right on it. The movement of the slider 401 drives the cutting motor base 502 to move, and the movement of the cutting motor base 502 drives the cutting motor 5 to follow the movement, so that the cutting disc 501 follows its left and right parallel movement, and further synchronously starts the cutting motor 5. The cutting motor 5 starts to drive the cutting disc 501 to rotate, so that the cutting disc 501 can cut the toilet paper roll from left to right or from right to left. After the cutting is completed, the chain plate 105 continues to run to drive the power block 106 to move. The thrust generated by the power block 106 pushes the cut toilet paper roll away from the cutting slot 203, and then continues the operation. Finally, the toilet paper roll is well cut.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
