Description

Technical Field

[0001] The utility model relates to the field of paper processing equipment design, in particular to a multi-stage air extraction energy-saving folding paper roller. Background Art

[0002] In current facial tissues, the paper is usually arranged in a folded form inside the packaging box, and currently the folding of the paper mostly relies on the use of a folding paper roller. Multiple folding grooves are arranged on the surface of a common folding paper roller. At the same time, multiple air extraction holes for air extraction are arranged on both side parts of the folding paper roller body. The multiple air extraction holes are in one-to-one correspondence and communication with the multiple folding grooves. During use, by relying on an external vacuum device to extract air from the air extraction holes, the paper can be partially sucked on the folding grooves to achieve folding.

[0003] However, in order to improve work efficiency, the upper limit of the width dimension of the original paper processed at one time is getting larger and larger, and correspondingly, the length dimension of the folding paper roller is also getting longer. Then, only extracting vacuum from both side parts of the folding paper roller, due to the large difference between the folding grooves in the middle of the folding paper roller body and both side parts of the folding paper roller, it will lead to a huge difference in the timing of the folding action of the paper on the folding grooves in the middle of the folding paper roller body, which easily causes the paper to be unable to be effectively folded or even distorted, affecting the quality of the folded finished product.

[0004] On the other hand, for a large folding paper roller with a long length, directly extracting vacuum from both side parts, in order to effectively extract air from the holes at each slot position in the middle of the folding paper roller body, the power requirement of the vacuum device is high and the energy consumption is relatively serious. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-stage air extraction energy-saving folding paper roller, which can solve one or more of the above problems.

[0006] According to one aspect of the utility model, a multi-stage air extraction energy-saving folding paper roller is provided, including a folding paper roller body and an air extraction component.

[0007] The folding paper roller body is provided with multiple annular grooves, and an air channel is arranged inside the folding paper roller body.

[0008] The air extraction component is provided with side holes, and an air outlet channel is arranged on the air extraction component. The air outlet channel is in communication with the side holes.

[0009] The air extraction components are rotatably installed on the annular grooves in one-to-one correspondence. An air flow channel is arranged on the side wall of the annular groove. The air flow channel is in communication with the air channel. The air flow channel on the annular groove is in communication with the side holes of the corresponding air extraction component.

[0010] The beneficial effects of the present utility model are as follows: In the present utility model, the air outlet channels of the air extraction components in the annular groove can be respectively connected to an external vacuum extraction device. Thus, when the present utility model is in use, by extracting air from each air extraction component, air can be successively extracted after passing through the paper folding grooves, air channels, air flow channels, side holes, and air outlet channels on the paper folding roller, so as to achieve the folding of paper towels. Therefore, the present utility model can facilitate the air extraction of various parts of the paper folding roller body, avoiding the problems that when a traditional single vacuum extraction device extracts air from the entire paper folding roller body, due to the overlong and overlarge size of the paper folding roller body, the air extraction intensity of each part varies greatly, and the response of air extraction at some positions is slow, ensuring the quality of the folded paper. At the same time, there is no need to use a specific high-power vacuum extraction device, effectively reducing energy consumption and improving efficiency.

[0011] In some embodiments, the air extraction component is provided with a reinforcing rib in the side hole, and the reinforcing rib is provided with a through hole. The setting of the reinforcing rib can improve the strength of the air extraction component, and the setting of the through hole can reduce the blockage of the air flow by the reinforcing rib during vacuum extraction, so as to ensure the effective progress of vacuum extraction.

[0012] In some embodiments, a plurality of paper folding grooves are evenly arranged on the circumferential surface of the paper folding roller body around the center of the paper folding roller body. The paper folding grooves linearly cross the annular groove and are arranged in the length direction of the paper folding roller body, and the paper folding grooves are communicated with the air channels.

[0013] In some embodiments, the paper folding groove is provided with an air extraction hole, and the paper folding groove is communicated with the air channel through the air extraction hole.

[0014] In some embodiments, there are a plurality of air channels, and the same air channel can be communicated with a plurality of paper folding grooves. This facilitates the simultaneous air extraction of a plurality of paper folding grooves by one air channel.

[0015] In some embodiments, the air extraction component is in an annular arc shape, and the air extraction component is provided with a notch. The annular arc-shaped air extraction component enables the air extraction component to effectively cooperate with the installation of the paper folding roller body, and the setting of the notch can effectively avoid the movement of other workpieces.

[0016] In some embodiments, connecting shafts are respectively arranged at both ends of the paper folding roller body. The setting of the connecting shafts can facilitate the connection of the paper folding roller body with an external power device to realize the rotation of the paper folding roller body.

All the origami slots 13 on the multiple origami slot rows are respectively connected to the multiple air ducts 15 through the air extraction holes 14 on them one by one, that is, the same air duct 15 can be connected to multiple origami slots 13.

[0028] The air extraction component 2 is in an arc shape, and the air extraction component 2 is provided with a notch 21. Side holes 22 are provided on the side of the air extraction component 2. In order to ensure the strength at the position where the side holes 22 are provided, reinforcing ribs 23 are further provided in the side holes 22 of the air extraction component 2. Through holes 231 are provided on the reinforcing ribs 23. There can be multiple through holes 231, and the through holes 231 can effectively connect the two sides of the reinforcing ribs 23 to facilitate the passage of air flow.

[0029] The air extraction member 2 is further provided with an air outlet interface 24, and an air outlet channel 241 is arranged on the air outlet interface 24. The air outlet channel 241 is communicated with the side hole 22.

[0030] The folding paper roller body 1 is further provided with annular grooves 10. There can be multiple annular grooves 10. Each row of folding paper grooves will straddle each annular groove 10. As required, some or all of the annular grooves 10 can be respectively and correspondingly installed with air extraction members 2. The air extraction members 2 are sleeved on the annular grooves 10, and the air extraction members 2 and the annular grooves 10 can rotate relatively. Thus, when the folding paper roller body 1 rotates, the air extraction members 2 can not rotate with it.

[0031] In addition, the size of the annular groove 10 matches the size of the air extraction member 2. After setting, the main body of the air extraction member 2 is embedded in the annular groove 10, and the air outlet interface 24 on the air extraction member 2 can penetrate out of the annular groove 10, and both sides of the air extraction member 2 can be respectively attached to the side walls of the annular groove 10.

[0032] The side wall of the annular groove 10 is further provided with an air flow channel 101.

In this embodiment, there are multiple air flow channels 101 arranged on the side wall of one side of each annular groove 10, and the multiple air flow channels 101 are respectively communicated with multiple air channels 15. And the air flow channel 101 on each annular groove 10 is communicated with the side hole 22 of the air extraction member 2 correspondingly arranged in the annular groove 10.

And during actual use, two such multi-stage air extraction energy-saving folding paper rollers are arranged side by side, and the folding paper grooves 13 on the two multi-stage air extraction energy-saving folding paper rollers can be staggered, so that the paper can be effectively folded after passing between the two multi-stage air extraction energy-saving folding paper rollers.

[0035] Specifically, when the paper is being folded, the two paper folding roller bodies 1 can rotate by relying on an external power device, so that the paper can pass through between the two paper folding roller bodies 1 driven by the paper folding roller bodies. During the movement of the paper, when the paper folding groove 13 on the paper folding roller body 1 comes into contact with a certain part of the paper, at this time, the vacuum device can work, the air extraction member 2 can extract air, and the air in the air extraction holes 14, air channels 15, air flow channels 101, side holes 22 and air outlet channels 241 on the paper folding groove 13 is extracted, then this part of the paper towel can be adsorbed on the paper folding groove 13, thereby realizing the folding of this position of the paper towel. Since the multi-stage air extraction energy-saving paper folding rollers are arranged staggeredly and there are multiple paper folding grooves 13, after the paper towel passes through the two paper folding rollers, the multi-position folding of the paper towel can be realized.

[0036] The above are only some embodiments of the present invention.
