Description

Technical Field

[0001] This utility model relates to the field of folding machine technology, specifically to a tissue paper folding machine. Background Technology

[0002] Facial tissue folding machines typically use two rolls of raw paper to draw paper strips. These strips are then cut at equal intervals according to the required tissue length, staggered, and stacked into piles. The piles are then further cut and packaged individually according to the tissue width. Existing tissue folding equipment suffers from significant tension during traction due to the large width of the paper strips. Furthermore, static electricity is generated during traction, leading to curling, shrinkage, and sticking of the paper strips after cutting, affecting folding quality and paper jams, thus impacting folding efficiency. Additionally, the intermittent conveying of tissue piles in these machines results in low automation in sorting and receiving, further reducing overall production efficiency. Therefore, a facial tissue folding machine needs to be developed to eliminate curling, shrinkage, and sticking caused by high tension during traction and cutting, and to remove static electricity from the paper strip surface, thereby improving folding quality and efficiency.

When the distance between the fourth sensor and the first shaft clamp is at its maximum, the third geared motor starts, and the first geared motor stops. The first front-and-back conveying assembly then drives the rear top support assembly to slide forward until the first shaft clamp and the first connecting rod are in a straight line, sliding the rear top support bracket directly below the folded tissues to be formed into a new tissue stack. A pair of fifth sensors are fixedly mounted on the second crossbeam and are used to control the second geared motor. The fourth geared motor, with its sensing ends all facing downwards, is directly opposite the corresponding first shaft clamp. When the second shaft clamp and the second connecting rod are aligned in a straight line, under the action of the second geared motor, the second vertical conveying assembly drives the second front-rear conveying assembly to slide downwards. Simultaneously, the fourth geared motor stops, causing the tissue stack on the front top support assembly to move vertically downwards. The sixth sensor is fixedly mounted on the side plate, with its sensing end facing inwards. When it is directly opposite the straight end of the outermost rear top support bracket, the first geared motor stops, and the third geared motor starts, causing the rear top support assembly to slide backwards until the rear top support bracket is pulled out from under the tissue stack.

A pair of antistatic devices 24 are respectively disposed directly below the corresponding lower wheel shafts 231.Both ends are fixedly connected to the corresponding side plates 12 and are parallel to the lower wheel axle 231 to eliminate static electricity on the paper tape. The transition roller assembly 25 includes transition roller connectors 251 and transition rollers 252. Two pairs of transition roller connectors 251 are fixedly connected to the corresponding side plates 12. By adjusting the deflection angle of the transition roller connectors 251, the paper tape is made to fit against the inner side of the antistatic device 24. Both ends of a pair of transition rollers 252 are rolledly connected to the corresponding transition roller connectors 251. By setting the traction feeding mechanism 2, the front and rear paper tapes pass through the front glue bending roller 211 and the rear glue bending roller 231 respectively. After the bending roller 213, the rollers are led out from the inside out and downwards from between the corresponding middle roller 221 and lower wheel shaft 231, passing sequentially through the inner side of the corresponding antistatic device 24 and the lower edge of the transition roller 252. Under the action of a pair of first gears 235, they drive a pair of lower knurling shafts 236 to rotate in opposite directions. This, in turn, via the corresponding belt 237, drives the corresponding upper knurling shaft 233 and lower wheel shaft 231 to rotate synchronously in opposite directions. Furthermore, via the corresponding lower gear 232 and middle gear 222, the corresponding middle roller 221 rotates synchronously in opposite directions, thus drawing the two paper strips into the rolling slitting mechanism 3.

The two ends of the air suction pipe 301 are fixedly mounted on corresponding side plates 12. On the front side of the front rubber bending roller 211, a pair of first air suction holes 301a and second air suction holes 301b are respectively provided on its front side and top surface, respectively, communicating with a pair of air suction hoods 304 on the corresponding sides. A pair of upper cutter shafts 302 are respectively horizontally arranged on the corresponding lower roller shafts 2. The inner side of the 31 is lower, and both ends are tumblingly connected to the corresponding side plate 12. Each has an upper blade 302a facing downwards. A pair of lower blade shafts 303 are laterally arranged below the inner side of the corresponding upper blade shaft 302, with both ends tumblingly connected to the corresponding side plate 12. Three lower blades 303a are equidistantly arranged radially. The blades have internal cavities and several suction holes on their surfaces. Both ends have axial connecting holes. Negative pressure is used to adhere the paper strip to the lower blade shaft 303, and as the lower blade shaft 303 rotates in opposite directions, it conveys the paper downwards. Two pairs of suction hoods 304 are movably sleeved at both ends of the corresponding lower blade shaft 303. Their inner sides are connected to the connecting holes at the ends of the corresponding lower blade shaft 303, and their other sides are fixedly connected to the inner side of the corresponding side plate 12. A pair of second... Gears 305 are fixedly connected to the left end of the corresponding lower cutter shaft 303 and mesh with the corresponding first gear 235. One end of each pair of upper cutter shaft swing arms 306 is fixedly connected to the end of the corresponding upper cutter shaft 302 and is located on the outside of the side plate 12 on the other side. A pair of second cylinders 307 are fixedly connected to the side plate 12, with their output ends rolling upwards and connected to the other end of the corresponding upper cutter shaft swing arms 306. The triangular sensing plate 308 is fixedly mounted on the right end of the lower cutter shaft 303 at the rear. The first sensor 309 is fixedly mounted on the outside of the right side plate 12, with its sensing end facing downwards toward the triangular sensing plate 308. The main synchronous pulley 310, the synchronous tensioning pulley 311, and the secondary synchronous pulley 312 are arranged from bottom to top in front of the triangular sensing plate 308 and pass through... The main synchronous belt drive connects to the front lower cutter shaft 303, causing it to rotate counterclockwise. This, in turn, drives the second gear 305 on the left side of the front shaft and the corresponding lower cutter shaft 303 to rotate counterclockwise. The main synchronous belt pulley 310 is fixedly connected to the main motor output shaft, and the secondary synchronous belt pulley 312 is fixedly connected to the right end of the front lower cutter shaft 303. Through the rolling slitting mechanism 3, the front and rear paper tapes pass between the corresponding upper cutter shaft 302 and lower cutter shaft 303 from the outside in, rotating in opposite directions with the pair of lower cutter shafts 303. When the triangular end of the triangular sensing plate 308 rotates to face the first sensor 309, both second cylinders 307 draw air and push upwards, driving the corresponding upper cutter shaft 302 to rotate via the corresponding upper cutter shaft swing arm 306.This causes the corresponding upper blade 302a to press downwards against the corresponding lower blade 303a, thereby cutting the front and rear paper tapes covering the corresponding lower blade 303a into single sheets of paper. After cutting the paper tapes, both second cylinders 307 release air, which drives the corresponding upper blade shaft 302 to rotate upwards and reset via the upper blade shaft swing arm 306, thus separating the upper blade 302a from the lower blade 303a.

[0032] See Figure 4 , Figure 5 , Figure 6The dispensing and folding mechanism 4 includes a rear dispensing assembly 41, a front dispensing assembly 42, a rear top folding assembly 43, a front top folding assembly 44, a third gear 45, a rotating assembly 46, a second sensor 47, and a third sensor 48.

The front dispensing assembly 42, arranged opposite to the rear dispensing assembly 41, is used to dispense the front tissue paper downwards and cooperates with the front top folding assembly 44 to fold the front tissue paper. It includes a front dispensing shaft 421 and front dispensing teeth 422, whose connection relationship is similar to that of the rear dispensing assembly 41 and will not be described again. The rear top folding assembly 43 includes a rear crossbeam 431, a third cylinder 432, a rear support mounting crossbeam 433, and a rear top folding bracket 434. The rear crossbeam 431 is laterally arranged behind the rear dispensing shaft 411, with both ends fixedly connected to the corresponding side plates 12. A pair of third cylinders 432 are fixedly connected to the rear crossbeam 431. The front end is fixedly connected to the rear support mounting beam 433. During normal operation, it is in a suction state. When a paper jam occurs, the third cylinder 432 releases air, which drives the rear top folding bracket 434 to retract via the rear support mounting beam 433, increasing the operating space for handling paper jams. The rear support mounting beam 433 is longitudinally slidably connected to the rear beam 431. The rear ends of several rear top folding brackets 434 are fixedly connected to the rear support mounting beam 433 and are staggered from the rear separating teeth 412. During normal operation, the top of the rear top folding bracket 434 engages with the rear separating teeth 412 to form a crease. The front top folding assembly 44 and the rear top folding assembly 434... The three components are arranged in a front-to-back configuration, including a front crossbeam 441, a front top-folding bracket 442, and a front bracket crossbeam 443. Their connection relationship is similar to that of the rear top-folding assembly 43, and will not be described again. A pair of third gears 45 are spaced between the rear shift shaft 411 and the front shift shaft 421, respectively meshing with the corresponding second gears 305, and both are fixedly connected to the outer side of the left side plate 12. The rotating assembly 46 includes a rotating bracket 461, a shift swing arm 462, a spring 463, a sensor fixing plate 464, a bolt 465, and an eccentric shaft 466. Each pair of rotating brackets 461 is provided with an upper bracket 461a and a lower bracket 461b.Each of the above is fixedly connected to the left end of the rear shift shaft 411 and the front shift shaft 421, respectively. A pair of upper supports 461a and corresponding lower supports 461b are rolled together. During normal operation, the upper supports 461a and lower supports 461b form a whole, and under the action of the shift swing arms 462, they drive the corresponding rear shift shaft 411 and front shift shaft 421 to rotate. The lower ends of the pair of shift swing arms 462 are rolled together with the lower ends of the corresponding lower supports 461b. The upper and lower ends of a pair of springs 463 are fixedly connected to the corresponding sensor fixing plates 464 and bolts 465, respectively. A pair of bolts 465 movably pass through the corresponding springs 463 and sensor fixing plates 464 and are fixedly connected to the corresponding upper supports 461a. The inner sides of a pair of eccentric shafts 466 are coaxially fixedly connected to the corresponding third gear 45, and the outer sides are rolled together with the upper ends of the corresponding shift swing arms 462. The second sensor 47 and the third sensor 48 are fixedly connected to the corresponding sensor fixing plates 464, with the sensing ends facing... When a paper jam occurs, the upper outer end of the lower bracket 461b abuts against the sensor fixing piece 464, increasing the distance between it and the corresponding second sensor 47 and third sensor 48. This causes the entire machine to stop and reset, facilitating timely handling of paper jams and preventing damage to the corresponding components. Through the separation and folding mechanism 4, when a misaligned single sheet of paper is conveyed along the inner surface of the corresponding lower cutter shaft 303 to the front end of the rear separation tooth 412 and the front separation tooth 422, a pair of third gears 45... Under the action of the second gear 305, a pair of eccentric shafts 466 are driven to rotate in opposite directions. These shafts, via a pair of distributing swing arms 462 and a rotating bracket 461, respectively drive the front distributing shaft 421 and the rear distributing shaft 411 to rotate in opposite directions. This, in turn, causes the front distributing teeth 422 and the rear distributing teeth 412 to oscillate synchronously up and down. In conjunction with the front folding bracket 442 and the rear folding bracket 434, the two sheets of tissue paper are simultaneously distributed and folded in a staggered manner, then slide down and stack along the rear folding bracket 434 and the front folding bracket 442.

The third synchronous pulley 537, the first tensioning pulley 538, and the fourth synchronous pulley 539 are connected by a synchronous belt drive. When the horizontal end of the rear top support bracket (552) approaches the longitudinally arranged conveyor, the second reduction motor (536) drives the first optical shaft (532) to rotate slightly. The first optical shaft (532) pushes the rear top support assembly (55) backward through the first shaft clamp (533) and the first connecting rod (534). After the horizontal end of the rear top support bracket (552) is pulled away from under the paper stack, under the action of the first up-down conveying assembly (51), the rear top support assembly (55) is driven to move upward to the highest point. Then, the second reduction motor (536) drives the first optical shaft 532 to rotate slightly. The shaft (532) rotates slightly, and the first optical shaft (532) pushes the rear top support assembly (55) forward through the first shaft clamp (533) and the first connecting rod (534), so that the horizontal end of the rear top support bracket (552) extends directly under the new paper stack. The second front and rear transfer assembly 54 is used to drive the front top support assembly 56 to slide back and forth. It is arranged in front of the first front and rear transfer assembly 53 and includes a second mounting plate 541, a second optical shaft 542, a second shaft clamp 543, a second connecting rod 544, a second crossbeam 545, a fourth reduction motor 546, a fifth synchronous pulley 547, a second tensioning pulley 548, and a sixth synchronous pulley 549.

A pair of fourth sensors 57 are fixedly installed above the first mounting plate 531, and are used to control the first reduction motor 515 and the third reduction motor 536 respectively. The sensing ends are all facing downwards, directly opposite the corresponding first shaft clamp 533. When the first shaft clamp 533 and the first connecting rod 534 are in a straight line, the first reduction motor 515 starts, and the third reduction motor 536 stops, causing the first up-down conveying assembly 51 to drive the first front-back conveying assembly 53 to slide downwards, and causing the paper stack on the rear support assembly 55 to move vertically downwards. When the distance between the fourth sensor 57 and the first shaft clamp 533 is at its maximum, the third reduction motor 536 starts, and the first reduction motor 515 stops.The first forward and backward conveying assembly 53 drives the rear top support assembly 55 to slide forward until the first shaft clamp 533 and the first connecting rod 534 are in a straight line. This slides the rear top support bracket 552 directly below the folded tissues to be formed into a new tissue stack. A pair of fifth sensors 58 are fixedly mounted on the second crossbeam 545, respectively controlling the second reduction motor 525 and the fourth reduction motor 546. The sensing ends of both sensors face downwards, directly opposite the corresponding first shaft clamp 533. When the second shaft clamp 543 and the second connecting rod 544 are in a straight line, under the action of the second reduction motor 525, the second up and down conveying assembly 52 drives the second forward and backward conveying assembly 54 to slide downwards. Simultaneously, the fourth reduction motor 546 stops, causing the paper stack on the front top support assembly 56 to move vertically downwards. The sixth sensor 59 is fixedly mounted on the side plate 12, with its sensing end facing inwards. When it is directly facing the straight end of the outermost rear top support bracket 552, the first reduction motor 515 stops, and the third reduction motor 536 starts, causing the rear top support assembly 55 to slide backwards until the rear top support bracket 552 is pulled out from under the paper stack. By setting up the top support conveying mechanism 5, when the first up-down conveying assembly 51 drives the rear top support assembly 55 to move downwards from the front of the highest point via the first front-rear conveying assembly 53, the second up-down conveying assembly 52 drives the second front-rear conveying assembly 546 to move downwards via the second front-rear conveying assembly 546. 54 drives the front support assembly 56 to move vertically upward from the lowest point. When the front support assembly 56 moves vertically upward to the highest point, the folded tissues are stacked on the rear support assembly 55. The second front-to-back transfer assembly 54 drives the front support assembly 56 to slide horizontally from the highest point towards the rear support assembly 55 until the front support bracket 562 is moved directly under the new folded tissues to be stacked. Then, the second up-down transfer assembly 52, via the second front-to-back transfer assembly 54, drives the front support assembly 56 to slide downward from the highest point until the rear support assembly 55 supports the new folded tissues to be stacked again. When the first up-down transfer assembly 51 passes through the first front-to-back transfer assembly... When component 53 drives the rear support component 55 to slide down to the front of the lowest point, the first front-to-back transfer component 53 drives the rear support component 55 to slide backward until the stack of tissues is completely placed on the vertically arranged conveyor. Then, the first up-down transfer component 51, driven by the first front-to-back transfer component 53, drives the rear support component 55 to slide upward from behind the lowest point to the highest point. Next, the first front-to-back transfer component 53 drives the rear support component 55 to slide horizontally from behind the highest point towards the front support component 56 until the rear support component 55 is moved directly under the new stack of folded tissues. Subsequently, the second front-to-back transfer component 54 drives the front support component 56 to slide forward and reset from the lowest point.

Initially, they are all vertically upward. By setting the pressing and leveling mechanism 6, when the horizontal section of the rear top support bracket 552 is pulled away from under the paper stack, a pair of fifth cylinders 65 draw air, which drives the number of pressure rods 68 to press down through the corresponding third shaft clamps 66 and the third optical axis 67, pressing and flattening the paper stack placed on the longitudinally arranged conveyor.
