Description

Technical Field

[0001] This invention relates to the field of tissue paper, and more particularly to a fully servo-driven automatic tissue paper counting machine. Background Technology

[0002] Existing tissue conveying devices use multiple sets of drive rollers staggered vertically to create a large pulling force on the tissues during the conveying process, preventing the tissues from sagging and the conveying speed from being mismatched. However, the tissues tend to wrinkle and bulge in the middle during the conveying process, which can lead to inaccurate cutting and tilted cutting positions. Furthermore, the wrinkles and bulges in the middle can cause the tissues in subsequent conveying processes to gradually shrink inward through the wrinkles, ultimately preventing the tissues from unfolding and being cut effectively.

[0003] Meanwhile, during the process of cutting the paper towels, due to the uneven force on both sides of the paper towels after cutting, the paper towels will have wrinkles, overlaps and shifts during transportation. In severe cases, it will affect the subsequent transportation of paper towels, and cause the equipment to be blocked, resulting in the machine not being able to operate normally, affecting production efficiency and cost.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention realizes the expansion of the paper towel to both sides by using the spiral structure that rotates to both sides on the expansion roller, so as to prevent the paper towel from wrinkling and folding during transportation.

[0016] By utilizing the arc shape on the upper side of the conveyor, the blocked tissues are pushed out when the conveyor rotates counterclockwise, preventing the tissues from clogging the device and causing it to malfunction.

[0017] The paper towels are supported by a rubber strip on the upper side of the conveyor. The arc-shaped structure on the front side of the rubber strip reduces friction during the paper towel support process, making the paper towels transported more effectively.

[0018] The threaded structure on the second drive roller, which rotates to the left and right, applies tension to the cut tissue paper on both sides, thereby stretching the tissue paper and preventing it from bunching up and wrinkling.

[0019] The outward-inclined spiral structure on the second driven roller applies an outward force to the end of the paper towel, thereby applying tension to the paper towel and preventing insufficient tension from causing wrinkles.

[0020] The ball bearings on the curved roller roll roll out due to friction with the paper towel when they come into contact with it, making the process of smoothing the middle of the paper towel more effective.

[0021] The outward-sloping protrusions on the movable block limit the paper towel and apply an outward pulling force. In conjunction with the second drive roller, the paper towel is pulled outward on both the front and back sides to prevent the paper towel from shifting, falling, or curling after cutting.

[0022] By contacting the paper towel with the electric smoothing block, the first extrusion plate causes the electric smoothing block to move on the paper towel during the rebound process, thereby smoothing the paper towel. Attached Figure Description

[0041] It also includes a conveying assembly, a stretching roller 3, a limiting rod 4, a flattening plate 5, a storage bin 6, a conveyor 7, a cutting assembly, and a folding counting assembly; the conveying assembly is installed on the two first support frames 1 and the second support frame 2; the stretching roller 3 is installed between the two second support frames 2; the surface of the stretching roller 3 is provided with a spiral rectangular structure extending to the left and right sides, which stretches the paper towel 8 from the middle to the left and right sides during the conveying process to prevent wrinkles from forming on the paper towel 8; the limiting rod 4 is installed on the conveying assembly; the flattening plate 5 is provided between the two second support frames 2; the stretching roller 3 is located to the left of the flattening plate 5; the storage bin 6 for storing the processed paper towel 8 is installed on the lower side of the two second support frames 2; the conveyor 7 is installed on the second support frame 2; the conveyor 7 is set as a semi-circular arc plate, and the upper side is set as an arc The shape, with a semi-circular arc structure, deflects at the center, conveying the tissue 8 while simultaneously clearing any blockages in the tissue 8 during rotation. A cutting component is positioned between the two second support frames 2; a folding counting component is installed between the two second support frames 2. The tissue 8 is conveyed to the cutting component via the conveying component, and the stretching roller 3 stretches the tissue 8 during conveying to prevent wrinkles. The flattening plate 5 lays the tissue 8 flat while pressing it onto the conveying component for transport. The conveying and cutting components work together to cut and convey the tissue 8. The folding counting component counts the folds of the cut tissue 8, thus counting the processed tissue 8. The processed tissue 8 is collected in the storage bin 6.

[0042] The upper side of the conveyor 7 is provided with rubber strips 7001 arranged at equal intervals and decreasing in length in an arc shape, and the front side of the rubber strips 7001 is set in an arc shape. Through reciprocating motion, the rubber strips 7001 reduce the friction force on the paper towel 8 during its reciprocating motion, thus preventing the paper towel 8 from wrinkling.

[0043] The conveying assembly includes a driver 101, a first driven roller 102, and a conveyor belt 103; a driver 101 is fixedly connected to the upper side of each of the two first support frames 1; a first driven roller 102 is fixedly connected to the front and rear sides of each of the two second support frames 2; two symmetrical conveyor belts 103 are fixedly connected between the two second support frames 2; by the cooperation of the driver 101 and the first driven roller 102, the paper towel 8 is conveyed while ensuring the tension of the paper towel 8 to prevent wrinkles, and the paper towel 8 is subsequently conveyed by the conveyor belt 103.

[0044] The cutting assembly includes a fixed frame 201, a drive unit 202, and a cutter 203; two fixed frames 201 are fixedly connected to the upper side of the second support frame 2; two drive units 202 are fixedly connected to the lower side of each of the two fixed frames 201; the drive unit 202 is an electric push rod; a cutter 203 for cutting paper towels 8 is fixedly connected to the lower side of the two drive units 202; the drive unit 202 and the cutter 203 cooperate to cut the paper towels 8 to a specified length during the conveying process.

[0045] The folding counting assembly includes a fan-shaped oscillator 301, a semi-circular fixing block 302, a connecting rod 303, a first drive roller 306, a fixing plate 307, a force-bearing plate 308, a wind baffle plate 309, a first extrusion plate 310, and a counter 311; two fan-shaped oscillators 301 are fixedly connected to the second support frame 2 on the right; two semi-circular fixing blocks 302 are movably connected to the two second support frames 2 on opposite sides; the center point of each semi-circular fixing block 302 and the center point of the conveyor 7 are on the same horizontal line; the two semi-circular fixing blocks 302 on the right are respectively fixedly connected to the adjacent fan-shaped oscillators 301; at least two connecting rods 303 are fixedly connected to each semi-circular fixing block 302; each connecting rod 303... The connecting rods 303 are all fixedly connected to the conveyor 7; the two second support frames 2 are movably connected to two front-to-back symmetrical first drive rollers 306; each of the two first drive rollers 306 is provided with an air suction hole 30601, which is used to absorb the paper towel 8 on the surface of the first drive roller 306 to prevent the paper towel 8 from falling off; each of the two first drive rollers 306 is movably connected to a wind baffle 309 on its inner side; the wind baffle 309 is always kept under the first drive roller 306, and the wind baffle 309 isolates the air suction hole 30601 on the lower side of the first drive roller 306, so that the paper towel 8 rotated to the lower side is not absorbed and hangs down; the two second support frames 2 are fixedly connected to each other. There are two symmetrical fixed plates 307; each fixed plate 307 is slidably connected to a force-bearing plate 308; several helical teeth 7002 are fixedly connected to the arc-shaped structure of the conveyor 7; the two force-bearing plates 308 are provided with inclined grooves 30801 that engage with the helical teeth 7002; at least four first extrusion plates 310 for paper towels 8 are fixedly connected to the opposite sides of the two force-bearing plates 308; two counters 311 are fixedly connected to the second support frame 2 on the right; the two counters 311 are movably connected to the lower side of the adjacent semi-circular fixed block 302; through the cooperation of the fan-shaped oscillator 301, the semi-circular fixed block 302 and the connecting rod 303, the conveyor 7 is centered on the semi-circular fixed block 302. The fan-shaped reciprocating motion conveys the tissue paper 8 to the first drive roller 306. The first drive roller 306 and the suction hole 30601 work together to attract the tissue paper 8 onto the first drive roller 306 and make it rotate. The air baffle 309 blocks the suction hole 30601 on the lower side of the first drive roller 306, causing the tissue paper 8 to fall between the first extrusion plates 310. The helical teeth 7002 and the inclined groove 30801 work together to make the force plate 308 slide on the fixed plate 307. The first extrusion plate 310 folds the falling tissue paper 8. The counter 311 counts the tissue paper 8 during the folding process driven by the semi-circular fixed block 302 and the first extrusion plate 310.

[0046] It also includes a rotary drive assembly, which includes a servo motor 304 and a gear 305; the servo motor 304 is fixedly connected to the first drive roller 306 at the front; a gear 305 is fixedly connected to each of the two first drive rollers 306; the two gears 305 mesh; the servo motor 304 drives the first drive roller 306 at the front to rotate, and the gears 305 drive the first drive roller 306 at the rear to rotate.

[0047] The specific operation of the folding counting device is as follows:

[0048] Because the thickness of the paper towel 8 being processed is too large during the initial conveying process, causing deviation during transport, the limiting rod 4 limits the paper towel 8 of different widths. The driver 101 drives the paper towel 8 to rotate, so that the end of the paper towel 8 passes under the first driven roller 102 and then over the stretching roller 3. Since the paper towel 8 has wrinkles and shrinkage during transport, the spiral structure extending to the left and right sides of the stretching roller 3 applies force to the paper towel 8 on both sides, thereby stretching the paper towel 8 and preventing wrinkles and folds. The flattened paper towel 8 is then laid flat on the conveyor belt 103 by the flat plate 5 for transport. When the paper towel 8 reaches the cutting length after passing the cutter 203, the driving component 2... 02 drives the cutter 203 to move downwards, thereby cutting the paper towel 8. At this time, the conveyor belt 103 continues to transport the paper towel 8. When the paper towel 8 is transported to the end of the conveyor belt 103, the fan-shaped oscillator 301 drives the semi-circular fixing block 302 to rotate. Through the semi-circular fixing block 302 as the central axis, it makes a semi-circular clockwise and counterclockwise reciprocating motion. The semi-circular fixing block 302 and the conveyor 7 share a common center point, thereby driving the conveyor 7 to rotate clockwise and counterclockwise. When the conveyor 7 rotates counterclockwise and approaches the conveyor belt 103, because the rubber strip 7001 is set with an arc structure on one side of the conveyor belt 103, the friction of the paper towel 8 on the upper side of the conveyor 7 is small during the process of the conveyor 7 approaching the conveyor belt 103, which facilitates the transport of the paper towel 8. The rubber strip 7001 on the upper side supports the tissue paper 8. The progressively decreasing length of the rubber strip 7001 gradually reduces friction on the tissue paper 8 during transport, minimizing friction at the ends of the tissue paper 8 and facilitating its landing on the first drive roller 306. However, some tissue paper 8 cannot be caught by the conveyor 7, causing it to accumulate between the conveyor belt 103 and the conveyor 7. As the conveyor belt 103 continuously transports tissue paper 8 to the conveyor 7, this accumulation occurs. Simultaneously, the conveyor 7 rotates counter-clockwise, and the arc-shaped structure on its upper side moves closer to the conveyor belt 103, pushing out the blocked tissue paper 8 and preventing blockage that could malfunction the device. During normal operation, when the conveyor 7 rotates clockwise away from the conveyor belt 103, the rubber strip 7001 on the upper side of the conveyor 7 has a straight edge structure on the other side. This results in greater friction between the paper towel 8 and the rubber strip 7001 when the conveyor 7 rotates, making the conveyor 7 more effective at conveying the paper towel 8 to the first drive roller 306. Consequently, the conveyor 7 can more effectively place the end of the paper towel 8 onto the first drive roller 306. An external air pump generates suction through the air holes 30601 on the first drive roller 306, thus adhering the paper towel 8 to the surface of the first drive roller 306. At this time, the servo motor 304 drives the first drive roller 306 to rotate clockwise, and the two gears 305 engage.The first drive roller 306 at the rear rotates counterclockwise, thereby conveying the tissues 8 on both sides between the two first drive rollers 306. To facilitate folding of the tissues 8, the front and rear ends of the first drive roller 306 adsorbing the tissues 8 are always positioned in the middle of the first drive roller 306 adsorbing the tissues 8. This allows the tissues 8 on the two first drive rollers 306 to interlock during subsequent folding. Because the baffle plate 309 blocks the air intake 30601 below the first drive roller 306, the air intake 30601 cannot adsorb the tissues 8 when they rotate to the lower side of the first drive roller 306. At this time, the fan-shaped oscillator 301 at the front drives the conveyor 7 to rotate, causing the inclined teeth 7002 below to engage with the inclined groove 30801, pushing the force plate 308 to slide on the fixed plate 307, thereby driving the first extrusion plate 310 to move. This causes the first extrusion plate 310 to press against the first drive roller 306 at the rear. The detached tissue 8 is folded, and then the rear tissue 8 is inserted onto the tissue 8 on the front first drive roller 306. At this time, the rear fan-shaped oscillator 301 drives the conveyor 7 to rotate, causing the rear first extrusion plate 310 to fold the detached tissue 8 on the front first drive roller 306, and then insert the front tissue 8 onto the rear first drive roller 306, causing the tissue 8 to reciprocate through folding. Simultaneously, as the fan-shaped oscillator 301 drives the conveyor 7 to rotate clockwise and counterclockwise, the semi-circular fixing block 302 rotates synchronously. Since the counter 311 is movably connected to the lower side of the semi-circular fixing block 302, when the first extrusion plate 310 folds the tissue 8, both the conveyor 7 and the semi-circular fixing block 302 rotate counterclockwise, causing the lower side of the semi-circular fixing block 302 to squeeze the counter 311, thereby counting the folding process of the tissue 8. After the folding count is completed, the tissue 8 is stored in the storage compartment 6.

[0049] Example 2

[0050] Based on Example 1, such as Figures 10-12As shown, it also includes a smoothing system, which includes a second extrusion plate 401, a connector 402, a second drive roller 403, a connecting plate 404, a second driven roller 405, an arc roller 406, a movable block 407, and an elastic element 408; a second extrusion plate 401 is fixedly connected to each of the two cutting blades 203 on their opposing sides; a connector 402 is rotatably connected to the lower side of each of the two second extrusion plates 401; a second drive roller 403 is rotatably connected to the lower side of each of the two connectors 402; the rotation direction of the second drive roller 403 is the same as that of the transmission plate 405. The conveyor belt 103 has the same transmission direction, and the initial height of the second drive roller 403 is lower than that of the cutter 203; two elastic elements 408 are fixedly connected to the opposing sides of the two second extrusion plates 401; the elastic elements 408 are torsion springs; a connecting plate 404 is provided between two adjacent elastic elements 408; at least four second driven rollers 405 are fixedly connected to the ends of the two connecting plates 404 away from the second extrusion plates 401; the second driven rollers 405 are provided with an outwardly inclined spiral structure, which applies pressure to both sides of the paper towel 8 through the outwardly inclined structure. The outward pulling force causes the tissue paper 8 to unfold during transport by the conveyor 7, preventing wrinkles from forming. An arc-shaped roller 406 is fixed to the side of each of the two connecting plates 404 away from the second extrusion plate 401. The arc-shaped roller 406 is located between the four second driven rollers 405. The arc-shaped roller 406 is designed in an arch shape, which guides the middle part of the tissue paper 8 to both sides through the arch structure, preventing the tissue paper 8 from arching and folding. Two movable blocks 407 are movably connected to the sides of each of the two connecting plates 404 away from the second extrusion plate 401. The cutter 203 drives the second extrusion plate 401 to move downward, which in turn drives the connector 402 to drive the second drive roller 403 to move downward. The second drive roller 403 first contacts and presses the tissue paper 8. Through the cooperation of the conveyor 7, the second extrusion plate 401 and the connecting plate 404, the second driven roller 405 and the arc roller 406 stretch the tissue paper 8 cut on the conveyor 7 to prevent wrinkles and folds. The movable block 407 pulls the two sides of the tissue paper 8 to prevent the front end of the tissue paper 8 from shifting.

[0051] The second drive roller 403 is provided with a spiral structure extending to the left and right sides. The spiral structure applies tension to the cut paper towel 8 to prevent the paper towel 8 from being untractioned and stretched at the front end during transportation, which would cause curling and deviation.

[0052] The curved roller 406 is equipped with multiple equally spaced ball bearings. The ball bearings reduce the friction with the middle part of the paper towel 8, making the smoothing of the middle part of the paper towel 8 more effective. This prevents the curved structure from hindering the transport of the paper towel 8 and causing the paper towel 8 to become clogged and piled up.

[0053] The lower side of the movable block 407 is provided with multiple inclined protrusions 40701 that tilt to the left and right. The outward tilting protrusions 40701 apply an outward pulling force to both sides of the paper towel 8 to prevent the front end of the paper towel 8 from shifting or folding during the conveyor 7's conveying of the paper towel 8.

[0054] The specific work of the smoothing system is as follows:

[0055] Because the paper towel 8 cannot be tensioned on both sides by the conveyor 7 during the conveying process, the paper towel 8 develops wrinkles and raised corrugated shapes. During the cutting process by the cutter 203, the second extrusion plate 401 on the cutter 203 moves downwards, which in turn moves the connector 402 and the second drive roller 403 downwards. Since the initial position of the second drive roller 403 is lower than the lowest point of the cutter 203, the second drive roller 403 contacts the paper towel 8 first during the downward movement of the cutter 203. While the second drive roller 403 rotates counterclockwise and cooperates with the conveyor belt 103 to convey the paper towel 8, it also cuts the paper towel 8 during this process. A tension is provided to ensure the paper towel 8 is cut neatly during the cutting process. Then, the cutter 203 continues to move downward to cut the paper towel 8, thereby driving the second extrusion plate 401 to extrude the connector 402. At this time, the second drive roller 403 applies left and right pulling force to the cut paper towel 8 through the threaded structure that rotates forward and backward, thereby stretching the paper towel 8 and preventing it from arching and wrinkling. When the second drive roller 403 conveys the front end of the paper towel 8 to the conveyor 7, the rear end of the paper towel 8 is still on the second drive roller 403. The downward movement of the second extrusion plate 401 drives the connecting plate 404 to move downward, thereby driving the second driven roller 405, the arc roller 406 and the movable block 407 on the connecting plate 404 to move downward. When the moving roller 405 contacts the tissue paper 8 on the conveyor 7, the clockwise rotation of the conveyor 7 causes the second driven roller 405 to rotate counterclockwise through friction with the tissue paper 8. The outward-inclined spiral structure on the second driven roller 405 applies an outward force to the end of the tissue paper 8, causing an outward pull on the left and right sides of the rear end of the tissue paper 8. This, in conjunction with the second drive roller 403, applies tension to the tissue paper 8, preventing insufficient tension and wrinkling. Since the tissue paper 8 arches in the middle during transport by the conveyor 7, the arc-shaped roller 406 on the second extrusion plate 401 smooths the arched portion to the left and right sides. To further enhance the smoothing effect of the arc-shaped roller 406... The ball bearings on the curved roller 406 contact the tissue paper 8, reducing friction between them and making the process of smoothing the tissue paper 8 more effective. Simultaneously, to prevent curling or shifting of the tissue paper 8 on the left and right sides, a movable block 407 contacts the left and right sides of the conveyor 7. This movable block 407 rotates and fits against the left and right sides of the conveyor 7, thus contacting the tissue paper 8 on the conveyor 7. The outwardly inclined protrusions 40701 on the movable block 407 limit the movement of the tissue paper 8 during transport by the conveyor 7, while simultaneously applying an outward pulling force to the front of the tissue paper 8. This, in conjunction with the second drive roller 403, ensures that both the front and rear sides of the tissue paper 8 experience outward pulling force.This tension at both ends of the paper towel 8 on the conveyor 7 prevents it from shifting, falling, or curling. Simultaneously, to prevent the connecting plate 404 from obstructing the transport of the paper towel 8 during its descent, it is connected to the second pressure plate 401 via an elastic element 408. When the connecting plate 404 is pressured by the conveyor 7, the elastic element 408 moves upward, thereby preventing the second driven roller 405, the arc roller 406, and the movable block 407 on the connecting plate 404 from obstructing the transport of the paper towel 8.

[0056] Example 3

[0057] Based on Examples 1 and 2, such as Figure 1 , Figure 2 , Figure 13 and Figure 14 As shown, it also includes an electric smoothing block 501; at least four electric smoothing blocks 501 are movably connected to each first extrusion plate 310; the first extrusion plate 310 is provided with a fitting groove 31001; the electric smoothing block 501 is stored in the fitting groove 31001 to prevent interference from the first extrusion plate 310 during the folding of the tissue paper 8, which would cause the tissue paper 8 to arch and misalign.

[0058] When the conveyor 7 rotates counterclockwise, it pushes the first extrusion plate 310 to fold the tissue paper 8. During this process, the electric smoothing block 501 is housed in the first extrusion plate 310 through the fitting groove 31001 to prevent interference during the folding process of the first extrusion plate 310, which could cause large-area arching and wrinkling of the tissue paper 8. When the conveyor 7 rotates clockwise, the first extrusion plate 310 springs back to its initial position. At this time, the electric smoothing block 501 unfolds and comes into contact with the tissue paper 8. During the springback process, the first extrusion plate 310 drives the electric smoothing block 501 to move on the tissue paper 8, thereby smoothing the tissue paper 8.
