Tissue cutting roll set cleaning device

Abstract

This invention relates to the field of tissue packaging machine technology, and more particularly to a tissue cutting roller assembly cleaning device. It includes a relaxation structure located below the folding rollers, which allows the upper end of the guardrail to move away from the folding rollers. It also includes a pull-out structure located on the side, comprising a pull-out operating port on the frame. A crease roller performs point-breaking processing on the paper strip, resulting in creases with point breaks. The folding rollers then fold the paper strip along the creases, and a claw assembly presses the paper strip to the receiving assembly. When the folding is irregular or the paper strip fails to break, tissue paper remains in the space enclosed by the guardrail, the receiving assembly, and the claw assembly. The machine stops, the receiving assembly lowers to its lowest position, the claws and the breaking assembly move to the outside, and then a linear motor actuates, increasing the gap between the guardrail and the folding rollers. The tissue paper is then pulled out through the pull-out operating port using tools such as pliers, completing the maintenance operation. The linear motor then drives the mounting frame to reset.

Description

Technical Field

[0001] This invention relates to the field of tissue packaging machine technology, and more particularly to a tissue cutting roller assembly cleaning device. Background Technology

[0002] The cutting roller assembly of the tissue packaging machine includes a frame, on which crease rollers and folding rollers are distributed from top to bottom. The crease rollers perform spot cutting on the paper strip to obtain creases with spot breaks. Then, the folding rollers fold the paper strip along the creases, and the paper strip is pressed to the receiving assembly by the claw assembly. After a certain quantity is reached, the paper strip is broken by the breaking assembly and sent out by the discharge conveyor belt. After further cutting and packaging, individual tissues are obtained. A railing is installed below the folding rollers. The railing is fixed to the frame by the mounting frame and limits the downward conveying of tissues.

[0003] During use, if the paper towel is not folded properly or fails to break, it will remain in the space enclosed by the railing, the paper receiving component, and the claw component. The machine needs to be stopped to remove the paper towel. At present, it is difficult to remove the paper towel through the gap of the paper receiving component, and it is easy to leave behind crumbs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a paper towel cutting roller assembly cleaning device.

[0005] The present invention is achieved through the following technical solution: a paper towel cutting roller assembly cleaning device, including a relaxation structure located below the folding rollers, through which the upper end of the railing can be moved away from the folding rollers; It also includes a pull-out structure located on the side, the pull-out structure including a pull-out operation port provided on the frame.

[0006] Furthermore, the relaxation structure includes a lifting drive structure connected to the mounting frame. The lifting drive structure includes a connecting seat mounted on the frame, a downward slide rail mounted on the connecting seat, the mounting frame connected to the slide rail via a slider, and a linear motor for driving the mounting frame to lift and lower is mounted on the connecting seat.

[0007] Furthermore, it also includes an auxiliary push-out structure located at the railing, through which the paper towel is pushed out towards the pull-out operation port.

[0008] Furthermore, the auxiliary ejection structure includes a push rod that can be inserted through the gap in the railing and push the tissue paper.

[0009] Furthermore, it also includes an auxiliary pull-off structure located at the upper end of the railing, which pulls the paper towel at the folded rollers apart.

[0010] Furthermore, the auxiliary breakage structure includes a transverse guide rod disposed at the upper end of the railing, which guides the cutting tool.

[0011] The beneficial effects of this invention are as follows: the crease roller performs spot-breaking processing on the paper tape to obtain creases with spot breaks, and then the folding roller folds the paper tape along the creases. The paper tape is then pressed to the receiving assembly by the claw assembly. When the folding is irregular or the paper fails to break, the paper towel will remain in the space enclosed by the railing, the receiving assembly, and the claw assembly. The machine stops, the receiving assembly falls to the lowest position, the claw and the breaking assembly move to the outside, and then the linear motor moves to increase the gap between the railing and the folding roller. Then, the paper towel is pulled out from the pull-out operation port by using tools such as pliers to complete the maintenance operation. The linear motor then drives the mounting bracket to reset.

[0014] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1 like Figure 1-3 As shown, a paper towel cutting roller assembly cleaning device includes a relaxation structure located below the folding rollers 3. The relaxation structure allows the upper end of the railing 4 to move away from the folding rollers 3. Specifically, the relaxation structure includes a lifting drive structure connected to the mounting frame 7. The lifting drive structure includes a connecting seat 8 mounted on the frame 1. A downward slide rail 9 is mounted on the connecting seat 8. The mounting frame 7 is connected to the slide rail 9 via a slider 10, thereby enabling it to move up and down along the slide rail 9. A linear motor 11 for driving the mounting frame 7 to move up and down is mounted on the connecting seat.

[0017] It also includes a pull-out structure located on the side, which includes a pull-out operation port 5 pre-reserved on the frame 1, and the pull-out operation port 5 corresponds to the position of the railing 4.

[0018] The paper towel cutting roller assembly cleaning device provided in this embodiment uses a crease roller 2 to perform spot-breaking processing on the paper strip, resulting in creases with spot breaks. Then, the paper strip is folded along the creases by the folding roller 3, and the paper strip is pressed to the receiving assembly by the claw assembly. When the folding is irregular or the paper strip fails to break, the paper towel will remain in the space enclosed by the railing 4, the receiving assembly, and the claw assembly. The machine stops, the receiving assembly falls to the lowest position, the claw and the breaking assembly move to the outside, and then the linear motor 11 moves to increase the gap between the railing 4 and the folding roller 3. Then, the paper towel is pulled out from the pull-out operation port 5 by using tools such as pliers to complete the maintenance operation. The linear motor 11 then moves to drive the mounting bracket 7 to reset.

[0019] During maintenance, it was discovered that when the tissue paper is long, it is easy to tear when pulled out from the pull-out operation port 5. Therefore, an auxiliary pushing structure is also included at the railing 4. The auxiliary pushing structure pushes the tissue paper towards the pull-out operation port 5. Specifically, the auxiliary pushing structure includes a push rod. The push rod can be inserted into the gap of the railing 4 and push the tissue paper. The push rod can be inserted from the top of the railing 4 to continuously push the tissue paper, or it can be inserted into each gap of the railing 4 to push the tissue paper segment by segment. The end of the push rod can be made into a tooth shape to avoid slipping when pushing the tissue paper.

[0020] It is worth noting that during use, the probability of irregular folding or failure to break is low. The probability of irregular folding or failure to break is higher mainly during the debugging stage. The paper towel cutting roller cleaning device can greatly improve the debugging efficiency.

[0021] Example 2 like Figure 4As shown, a paper towel cutting roller assembly cleaning device, unlike embodiment 1, also includes an auxiliary breakage structure located at the upper end of the railing 4. The auxiliary breakage structure breaks the paper towel at the folding roller 3. Specifically, the auxiliary breakage structure includes a transverse guide rod 12 installed at the upper end of the railing 4. The guide rod 12 can guide the cutting tool. The guide rod 12 can be a structure that is easy to obtain, such as round steel, rectangular tube, or profile. In this embodiment, the guide rod 12 is made of aluminum alloy profile with a rectangular cross-section. It is fixed to the upper end face of the railing 4 by countersunk bolts, so as not to affect the smoothness of the upper end face.

[0022] When the linear motor 11 drives the railing 4 to move down, the distance between the guide rod 12 and the folding roller 3 increases. The hand-held cutting knife is operated. The cutting knife is connected to the operating handle. The operating handle is supported by the guide rod 12 and slides along the guide rod 12, which enables the cutting knife to move laterally in a straight line to cut the paper towel connection near the folding roller 3, reducing the resistance when pulling out the paper towel from the pull-out operating port 5.

[0023] The test also found that the introduction of guide rod 12 can position the upper ends of each railing 4, thereby improving the anti-loosening and deformation performance of the railing 4.

[0024] Example 3 like Figure 5 As shown, a paper towel cutting roller cleaning device differs from Embodiment 2 in that, due to limited installation space, the guide rod 12 has a smaller size. When the guide rod 12 is long, it is prone to deformation during storage and transportation. In this embodiment, the guide rod 12 is designed as a multi-segment structure, and the end of any segment of the guide rod 12 is fixed to the upper end of the railing 4 by countersunk bolts, thereby avoiding interference between the end of the guide rod 12 and the paper towel.

[0025] A single-segment guide rod 12 is connected to 3-6 railings 4.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
