Description

Technical Field

[0001] The utility model relates to the technical field of facial tissue folding equipment, in particular to a fully automatic facial tissue folding machine with a four-knife structure. Background Art

[0002] The working principle of a facial tissue folding machine is to cut the base paper with a knife roller, fold it alternately into hinged rectangular sheets, and then package it into finished tissue paper. The machine mainly consists of a paper feed mechanism, a folding mechanism, a load-bearing mechanism, and a paper separator. The base paper enters the folding mechanism through the paper feed mechanism, where it is continuously cut and folded. The load-bearing mechanism below gradually moves downward as the number of sheets increases. When the specified number of sheets is reached, the paper separator inserts into the paper to complete the quantitative separation.

[0003] The base paper produced by existing facial tissue papermaking machines is generally around 2.8 to 5 meters wide. The total number of tissues that can be produced per unit time is limited by the base paper width and the folding rate. While maintaining the same folding rate, production needs to be increased by increasing the base paper width. To achieve this, the length of the folding roller must be increased. This length is limited by the roller diameter, so as the roller length increases, its diameter also needs to increase to prevent deformation caused by excessive roller length. The circumference of the folding roller must be a multiple of the width of the finished tissue paper. In existing fully automatic facial tissue folding machines with a four-roller, four-knife structure, the circumference of the folding roller is generally three times the width of the finished tissue paper. This means that the folding roller can cut and fold three sheets of paper in one rotation. Therefore, to increase the length of the folding roller, its circumference needs to be increased to four times or more the finished tissue paper specifications, significantly increasing its diameter. After the roller diameter increases, when producing tissue paper of the same specifications, the position of the paper outlet below the folding mechanism remains unchanged, but the paper separation mechanism extending into the paper outlet is interfered with by the roller with increased diameter, resulting in an increase in the height difference between the paper outlet and the paper receiving position, causing uneven folding, excessive width at the lower end of the folded finished tissue paper, unstable separation, and the separated paper being very loose. Utility Model Content

[0004] The present invention aims to at least solve the technical problem in the prior art that "after the roller diameter is increased, when producing tissue paper of the same specification, the position of the paper outlet below the folding mechanism remains unchanged, but the position where the paper separation mechanism extends into the paper outlet is interfered with by the roller with the increased diameter, resulting in an increase in the height difference between the paper outlet and the paper receiving position, causing uneven folding, excessive width at the lower end of the folded finished tissue paper, unstable separation, and very loose separated paper." To this end, the present invention proposes a fully automatic facial tissue folding machine with a four-blade structure, which has a paper separation fork assembly that can swing from under the large-diameter roller and insert into the paper outlet area, ensuring that the specifications of the tissue paper produced remain unchanged, improving production efficiency, and enhancing the production specifications and production efficiency of the equipment.

[0045] Reference below Figures 1-8The invention describes a fully automatic facial tissue folding machine with a four-blade structure according to an embodiment of the invention.

[0046] like Figures 1-8 As shown, the four-blade fully automatic facial tissue folder includes a frame 500, a pulling roller assembly 530, a fixed blade shaft assembly 540, a folding roller assembly 550, a support assembly 560, and a paper separation fork assembly 570. A paper inlet 510 and a paper outlet 520 are located above the frame 500. The paper inlet 510 and the paper outlet 520 are vertically connected. The base paper enters the paper inlet 510 via the pulling roller assembly 530. After being cut and folded by the fixed blade shaft assembly 540 and the folding roller assembly 550, the paper is stacked at the paper outlet 520 below. The support assembly 560 is used to support the paper below the paper outlet 520, and the paper separation fork assembly 570 is used to stack the paper according to the set number of stacking layers.

[0047] Specifically, a pulling roller assembly 530 is disposed above the paper inlet 510 to guide the base paper into the paper inlet 510. Two sets of pulling roller assemblies 530 are provided, one on each side above the paper inlet 510. The base paper on each side enters the paper inlet 510 through the corresponding pulling roller assembly 530. The pulling roller assembly 530 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0048] The fixed blade shaft assembly 540 is disposed below the pulling roller assembly 530. The folding roller assembly 550 is also disposed below the fixed blade shaft assembly 540 and abuts against the fixed blade shaft assembly 540. The pulling roller assembly 530, fixed blade shaft assembly 540, and folding roller assembly are all disposed on both sides of the paper outlet 520. The rollers of the fixed blade shaft assembly 540 and folding roller assembly 550 perform operations such as splitting and embossing the base paper, a technical solution well known to those skilled in the art. The main improvement in this embodiment is the structure of the paper separation fork assembly 570.

[0049] Existing four-roller fully automatic folding machines typically use a three-knife structure, meaning the folding roller is equipped with three bed knives, capable of cutting and folding three sheets of paper per rotation. In this embodiment, the folding roller assembly 550 has a larger roller diameter and is axially equipped with four sets of bed knives. This allows the folding roller assembly 550 to cut and fold four sheets of paper per rotation. At the same rotational speed, the folding roller assembly 550 in this embodiment achieves a faster folding rate, effectively improving the production efficiency of the folding machine.

[0050] The support assembly 560 is positioned below the paper outlet 520 and rises and falls along the paper outlet 520 to carry the paper removed from the paper outlet 520 and transport it to the next station. In this embodiment, the support assembly 560 is primarily located below the paper outlet 520, at a distance from the rollers of the folding roller assembly 550. This allows the existing vertical lifting structure to accommodate folding machines with large-diameter rollers.

[0051] The paper separation fork assembly 570 is located on the other side below the paper outlet 520. The paper separation fork assembly 570 moves up and down below the paper outlet 520, approaches the paper outlet 520, and inserts into the paper extraction area to separate the paper. The paper separation fork assembly 570 includes a paper separation base 100, a paper separation structure, and a sliding link 330.

[0052] The paper separation base 100 adopts a frame structure, and its two ends are movably connected to the frame 500 of the folder. The paper separation base 100 is driven by a conveyor belt structure and a motor to reciprocate along the paper stacking direction, that is, close to or away from the paper outlet 520. A first guide rail mounting plate 110 is provided at each end of the paper separation base 100, and a paper separation guide seat 120 is provided on the first guide rail mounting plate 110. A second guide rail mounting plate 130 is provided in the middle area of ​​the paper separation base 100, and a support guide seat 140 is provided on the second guide rail mounting plate 130. Specifically, the paper separation base 100 is provided with two sets of paper guide seats 120, which are provided on the first guide rail mounting plates 110 at both ends of the paper separation base 100. The support guide rail seat 140 is installed on the second guide rail mounting plate 130. At least one group of support guide rail seats 140 is provided. The actual number of support guide rail seats 140 is adjusted according to the length of the paper separation base 100. In this embodiment, two groups of support guide rail seats 140 are provided.

[0053] The paper separation structure includes a paper separation base 200 and paper separation forks 210 arranged at equal intervals along the length of the paper separation base 200. Fork shaft mounting seats 220 are rotatably connected at both ends of the paper separation base 200. The bottom of the fork shaft mounting seats 220 is slidably connected to the paper separation guide seat 120 via guide rails. Specifically, the fork shaft mounting seats 220 slide on the paper separation guide seat 120 via slide rails, and the two ends of the paper separation base 200 are connected to the fork shaft mounting seats 220, so that the paper separation base 200 can move back and forth along the direction in which the slide rails are set, causing the paper separation forks 210 to move closer to or further away from the paper outlet 520.

[0054] One end of the sliding link 330 is hingedly connected to a support rail connector 340. The support rail connector 340 is slidably connected to the slide rail of the support rail base 140 and abuts the paper separation base 200. Specifically, the paper separation base 200 is pushed by the sliding link 330 as it slides along the slide rail of the paper separation guide base 120. The support rail connector 340 slides along the guide rail of the support rail base 140, thereby enabling the support rail connector 340 to push the paper separation base 200 to move.

[0055] The surfaces of the paper separation guide seat 120 and the support guide seat 140 are respectively inclined, with the difference in the inclination angle between the two surfaces being 1° to 6°. When the fork shaft mounting seat 220 and the support guide connecting seat 340 are located at the bottom of the inclined surface, the paper separation fork 210 is placed in an inclined position. When the fork shaft mounting seat 220 and the support guide connecting seat 340 move toward the top of the inclined surface, the paper separation base 200 drives the paper separation fork 210 to flip and insert into the paper drawer. The paper separation base 200 rises and simultaneously drives the paper separation fork 210 to swing and insert into the paper drawer.

[0056] Specifically, there is an angle difference between the surface inclinations of the paper separation guide seat 120 and the support guide seat 140. When the paper separation base 200 is in the initial state, the paper separation fork 210 is located at the lowest end of the surface of the paper separation guide seat 120 and the support guide seat 140. At this time, the paper separation fork 210 is tilted and placed one after another. As the paper separation base 200 approaches the paper outlet 520, the paper separation base 200 slides along the guide surface with a larger inclination angle. At this time, the paper separation base 200 swings around the fork shaft mounting seat 220, driving the paper separation fork 210 to swing. When the paper separation base 200 reaches the top of the inclined surface, the paper separation fork 210 is inserted into the paper extraction area and is in a vertical state. Then, the paper separation base 100 is lowered and away from the paper outlet 520 under the action of the transmission belt, realizing the oblique insertion of the paper separation fork 210, avoiding the bottom of the large-diameter roller and swinging in an arc to insert the paper. This solves the problem that the traditional paper separation fork 210 cannot be inserted into the paper outlet of the original paper extraction specification after the folder roller is enlarged.

[0057] The tilt angle of the paper separation guide 120 and the support guide 140 determines the height at which the paper separation fork rises when inserted. The angle difference between the two determines the swing angle of the paper separation fork 210. Adjusting the tilt angle of the paper separation guide 120 and the support guide 140 changes the height at which the paper separation fork rises when inserted, and adjusting the angle difference between the two determines the swing angle of the paper separation fork 210 to accommodate rollers of varying diameters. Increasing the roller diameter, combined with the four sets of bottom blades in the folding roller assembly, effectively improves the paper extraction and folding efficiency of the folding device.

[0058] In some embodiments of the present invention, Figures 1-8 As shown, the drive structure includes a drive motor 400 and a transmission shaft 410. The output end of the drive motor 400 is in driving connection with the transmission shaft 410, and the transmission shaft 410 is keyed to the other end of the sliding link 330. The drive motor 400 cooperates with the transmission shaft 410 to transmit power to the sliding link 330, driving the sliding link 330 to flip, thereby pushing the paper separation base 200 to reciprocate and extend.

[0059] In some embodiments of the present invention, Figure 3-Figure 6As shown, the surfaces of the paper-separating guide rail seat 120 and the supporting guide rail seat 140 are respectively inclined, and the surface inclination angle of the supporting guide rail seat 140 is 2° greater than the surface inclination angle of the paper-separating guide rail seat 120. Specifically, the angle difference adopted in this embodiment is 2°, and the surface inclination angle of the supporting guide rail seat 140 is greater than the surface inclination angle of the paper-separating guide rail seat 120. As the paper-separating base 200 is pushed out, the fork shaft mounting seat 220 slides along the slide rail of the paper-separating guide rail seat 120, and the supporting guide rail connecting seat 340 slides along the slide rail of the support guide rail seat 140. When the angle difference between the two slide rails gradually increases, the supporting guide rail connecting seat 340 pushes the paper-separating base 200 to swing, and the two ends of the paper-separating base 200 rotate around the fork shaft mounting seat 220, thereby realizing the swing insertion of the paper-separating fork 210.

[0060] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, it includes a transmission connecting rod 310, one end of the transmission connecting rod 310 is connected to the side wall of the paper separation base 200, and the other end is key-connected to the transmission shaft 410. When the transmission shaft 410 rotates, the transmission connecting rod 310 pushes the paper separation base 200 to extend or retract.

[0061] Specifically, the sliding link 330 primarily adjusts the swing direction of the paper separation base 200, while the drive link 310 acts as a power transmission mechanism to drive the paper separation base 200 along the slide rails. Both the drive link 310 and the sliding link 330 are keyed to the drive shaft 410, allowing them to operate synchronously when the drive shaft 410 rotates. The drive link 310 is responsible for pushing the paper separation base 200, while the sliding link 330 is responsible for adjusting the angle of the paper separation base 200.

[0062] Furthermore, two groups of transmission links 310 and sliding links 330 are provided, distributed in the middle area of ​​the paper separation base 100. Specifically, the number of transmission links 310 and sliding links 330 provided is adjusted according to the length of the paper separation base 100. In this embodiment, the transmission links 310 are provided on one side of the sliding links 330. The transmission links 310 can also be provided on either side of the transmission shaft 410.

[0063] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the end of the transmission connecting rod 310 is rotatably connected to the transmission connecting seat 320, and the transmission connecting seat 320 is connected to the side wall of the paper separation base 200. Specifically, the transmission connecting seat 320 is hinged to the end of the transmission connecting rod 310, and the transmission connecting seat 320 is connected to the side wall of the paper separation base 200 by screws. When the transmission connecting rod 310 swings, the transmission connecting seat 320 links with the paper separation base 200 to move.

[0064] In some embodiments of the present invention, Figure 5 and Figure 6As shown, a swing connection seat 342 is provided on the side of the support guide rail connection seat 340 close to the paper separation base 200. The swing connection seat 342 is connected to the paper separation base 200, and the paper separation base 200 and the swing connection seat 342 swing synchronously around the rotation axis of the swing connection seat 342.

[0065] Furthermore, the swing connection base 342 has an L-shaped structure, with the long side of the swing connection base 342 connected to the bottom of the paper separation base 200 and the short side abutting the side wall of the paper separation base 200. Specifically, the long side and the short side of the swing connection base 342 are always in contact with each other, and the swing connection base 342 rotates around the connection point of the support rail connection base 340, thereby driving the paper separation base 200 to swing a certain angle.

[0066] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, a connecting rod seat 341 is provided on the top of the support rail connecting seat 340, and the connecting rod seat 341 is rotatably connected to the end of the sliding connecting rod 330. Specifically, the connecting rod seat 341 is detachably connected to the support rail connecting seat 340, and the connecting rod seat 341 and the sliding connecting rod 330 are plugged in by pins.

[0067] In some embodiments of the present invention, Figure 5-Figure 8 As shown, a swing bearing 221 is disposed within the fork shaft mounting seat 220, and a connecting shaft 201 is disposed at the end of the paper separation base 200. The connecting shaft 201 is connected to the inner ring of the swing bearing 221, and the paper separation base 200 swings around the connecting shaft 201. Specifically, the outer ring of the swing bearing 221 is embedded in the fork shaft mounting seat 220, and the inner ring of the swing bearing 221 is sleeved with the connecting shaft 201 of the paper separation base 200, allowing the paper separation base 200 to swing around the fork shaft mounting seat 220.

[0068] In some embodiments of the present invention, Figure 3 and Figure 7 As shown, a buffer assembly 222 is provided on one side of the fork shaft mounting base 220. The buffer assembly 222 is in releasable, elastic contact with the paper separation base 100. Specifically, the buffer assembly 222 utilizes a hydraulic buffer. When the fork shaft mounting base 220 reaches the end of its travel, the push rod of the hydraulic buffer abuts the end surface of the paper separation base 100, thereby mitigating the vibration of the fork shaft mounting base 220 upon its arrival. The buffer assembly 222 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.
