Description

Technical Field

[0001] The utility model relates to the field of toilet paper roll production equipment, in particular to a toilet paper cutting device. Background Art

[0002] Toilet paper is mainly used for daily hygiene in people's lives and is one of the indispensable paper types for the masses. There are many raw materials for making toilet paper, and commonly used raw materials include cotton pulp, wood pulp, bamboo pulp, straw pulp, etc. The finished toilet paper is generally in roll form, which requires the long toilet paper rolls produced initially to be cut at fixed distances during the production and processing of toilet paper. In the prior art, when cutting toilet paper rolls, manual feeding and control of the length of the paper rolls are used, which has high labor intensity, low safety factor, easy to hurt hands, low efficiency, low precision, and affects product quality.

[0003] In order to solve the above technical problems, a Chinese patent document (publication number CN215037811U) discloses a toilet paper roll fixed-distance cutting device, including a main frame, a sliding frame connected to the front side of the main frame, a cutting table for placing toilet paper rolls slidably connected above the sliding frame, and a table cylinder capable of pushing the cutting table to move forward and backward is connected to the front side of the sliding frame; a reciprocating saw connected to the main frame and capable of cutting in a vertical direction is provided on the rear side of the cutting table, and a saw blade groove allowing the reciprocating saw to pass through is provided on the cutting table; a fixed-distance baffle is connected to one side of the top surface of the cutting table; a blanking cylinder connected to the cutting table is provided between the reciprocating saw and the fixed-distance baffle; a pushing component capable of continuously pushing the toilet paper roll backward is connected above the cutting table.

[0004] The above technical solution uses a reciprocating saw, a fixed-distance baffle and a pushing component to continuously push the toilet paper roll backward for cutting.

In addition, the position of the toilet paper roll is not fixed well during cutting, and the toilet paper roll is prone to offset during cutting, thereby affecting the cutting quality.

[0027] Reference will now be made in detail to the embodiments disclosed in the present invention, examples of which are described herein and illustrated in the accompanying drawings. Although the present invention will be described in conjunction with the embodiments and / or examples, they do not limit the present invention to these embodiments and / or examples. On the contrary, the present invention discloses alternatives, modifications and equivalents.

[0028] In e.g. Figure 1 In the generally shown embodiment, the sanitary paper cutting device of the utility model comprises a frame body and a cutting body which are relatively arranged in position, the frame body is provided with an input conveying mechanism, a cutting table 3 and an output conveying mechanism in sequence along its conveying direction, and the cutting body has a cutting mechanism facing the cutting table 3.

[0029] The cutting mechanism includes a driving motor, a driving shaft 9 and a plurality of rotating blades 10. The rotating blades 10 are in a cross-shaped structure. The output shaft of the driving motor is axially connected to the driving shaft 9. The driving shaft 9 is parallel to the cutting table 3 along its axial direction. A plurality of strip grooves 8 are evenly distributed along the driving shaft 9 on the cutting table 3. The positions of the plurality of strip grooves 8 correspond one by one to the positions of the plurality of rotating blades 10. The plurality of rotating blades 10 are sleeved on the driving shaft 9 and evenly distributed along the axial direction of the driving shaft 9. A plurality of fixed bearings 11 are evenly distributed on the driving shaft 9 along its axial direction. Adjacent fixed bearings 11 are located on both sides of the rotating blade 10 and lock both sides of the rotating blade 10. All rotating blades 10 pass through the corresponding strip grooves 8 synchronously and respectively.

[0030] The utility model utilizes an input conveying mechanism and an output conveying mechanism to drive and transport the two ends of the toilet paper roll; when the input conveying mechanism conveys the toilet paper roll to the cutting table 3, the cutting mechanism on the cutting body starts to operate, and by starting the driving motor, the driving shaft 9 is driven to rotate, and all the rotating blades 10 on the driving shaft 9 rotate synchronously. Because the positions of the multiple rotating blades 10 correspond to the positions of the multiple strip-shaped slots 8 one by one, all the rotating blades 10 rotate synchronously and pass through the corresponding strip-shaped slots 8 at the same time, and the toilet paper roll is cut into multiple sections at one time along its length direction, thereby improving the cutting efficiency.

[0031] Among them, the frame body includes an upper frame 2 and a lower frame 1. The upper frame 2 can move toward the lower frame 1. A channel for toilet roll paper to pass through is formed between the upper frame 2 and the lower frame 1. The cutting table 3 is located in the middle of the channel. The input transmission mechanism is located at the input end of the channel, and the output transmission mechanism is located at the output end of the channel.

[0032] The top of the upper frame 2 is connected with a moving shaft 12, and the other end of the moving shaft 12 is connected to the output shaft of the telescopic cylinder. The telescopic cylinder drives the moving shaft 12 to move up and down, and drives the upper frame 2 to move toward or away from the lower frame 1, thereby changing the width of the channel to adapt to the cutting of toilet rolls of different sizes.

[0034] This solution utilizes the first conveyor belt of the upper input conveyor mechanism 6 combined with the first conveyor belt of the lower input conveyor mechanism to clamp the upper and lower surfaces of the toilet paper roll, so that the upper and lower surfaces of the toilet paper roll are squeezed and driven to move along the conveying direction.

[0035] The output conveying mechanism includes an upper output conveying mechanism 4 arranged on the upper frame 2, and a lower output conveying mechanism 5 arranged on the lower frame 1. The position of the upper output conveying mechanism 4 corresponds to the lower output conveying mechanism 5. The upper output conveying mechanism 4 and the lower output conveying mechanism 5 both include a second driving wheel and a second driven wheel. A second conveying belt is wound around the second driving wheel and the second driven wheel. The belt surface of the second conveying belt of the upper output conveying mechanism 4 corresponds to the belt surface of the second conveying belt of the lower input conveying mechanism and forms an extrusion driving force on the toilet paper roll.

There is no need for manual operation of the cutting process, which improves the safety factor and production progress. The production efficiency is further improved by directly completing the feeding process, saving labor costs.
