[0030] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1 and Figure 2 , 3This invention provides a folding device for paper towel production, including a base platform 1 for folding and unloading paper towels. A top platform 3 is mounted on the top of the base platform 1 via a bracket 2. The top of the top platform 3 has an opening, and a stacking platform 4 is arranged inside the opening. Several transverse cutters 5 are arranged on the top of the stacking platform 4, which is connected to the base platform 1. A self-cleaning folding mechanism 6 is connected to the top of the top platform 3 via several fixing frames 7. A counting mechanism 8 for counting the folds of paper towels is arranged on the fixing frames 7. Auxiliary arm assemblies 9 are installed on both sides of the top of the top platform 3. The two auxiliary arm assemblies 9 are mechanically linked with the self-cleaning folding mechanism 6 to press the folded edges of the paper towels. The two auxiliary arm assemblies 9 cooperate with the transverse cutters 5 to cut the paper towels.

[0032] The self-cleaning folding mechanism 6 includes two reciprocating drive mechanisms 61. The output ends of the two reciprocating drive mechanisms 61 are connected to end blocks 62. Two conveying rollers 63 are movably sleeved on the inner sides of the two end blocks 62. The two conveying rollers 63 are driven to rotate by an anti-rotation drive mechanism 66. Dust collection hoods 64 are provided on the outer sides of the two conveying rollers 63. The two dust collection hoods 64 are interconnected by a three-way pipe 67. The three-way pipe 67 is connected to a centrifugal fan through a flexible hose. The top of the two dust collection hoods 64 is connected to an L-shaped air duct plate 65. The two ends of the two dust collection hoods 64 are connected to the inner sides of the two end blocks 62 and respectively fit against the two conveying rollers 63.

[0033] Reference Figure 4 The auxiliary arm assembly 9 includes two fixed blocks 91, two support frames 95, and a push rod 910. The inner sides of the two support frames 95 are provided with inclined grooves, within which inclined sliding arms 99 are movably sleeved. A pressure plate 912 is fixedly connected to the bottom of the inclined sliding arm 99, and a connecting rod 97 is movably sleeved to the top of the inclined sliding arm 99 via two connecting frames 96. The two fixed blocks 91 are fixedly connected to the bottom of two reciprocating drive mechanisms 61. Moving rods 92 are slidably sleeved within the inner cavities of both reciprocating drive mechanisms 61. One end of the moving rod 92 is provided with a push plate 93, which is connected to the fixed blocks 91 via a spring 94. The other end of the moving rod 92 is movably sleeved to the connecting rod 97 via a rotating column 911. The push rod 910 is fixed to the output end of the reciprocating drive mechanism 61. In the initial state, the spring force of spring 94, in conjunction with the push plate 93, allows the moving rod 92 to move towards the push rod 910. At this time, the moving rod 92 exerts a lateral pulling force on one end of the connecting rod 97. Since the height of the connecting rod 97 and the spring 94 connection end is limited, the bottom end of the connecting rod 97 exerts a downward force on the inclined sliding arm 99, causing the inclined sliding arm 99 to slide along the support frame 95 in the inclined groove. At this time, the pressure plate 912 moves downward along an inclined trajectory, achieving the effect of pressing the folded edge of the paper towel. When the reciprocating drive mechanism 61 runs and drives the push rod 910 to abut against the push plate 93 and move the moving rod 92, the inclined sliding arm 99 will have the opposite movement relationship, causing the pressure plate 912 to move upward at an angle. This can prevent the next folded paper towel from accumulating on the top of the pressure plate 912.

[0034] Reference Figure 4 The inclined arm 99 is equipped with a longitudinal cutting device 98. The top of the pressure plate 912 is provided with a longitudinal knife groove 913 that extends to the bottom. The output end of the longitudinal cutting device 98 passes through the longitudinal knife groove 913. The longitudinal cutting device 98 is used for longitudinal cutting of paper towels. The number of folded layers of a single paper towel is set according to the production process. When the number of folded layers of the paper towel is set, it is longitudinally cut by the longitudinal cutting device 98 to process a single paper towel.

[0035] Reference Figure 5 The longitudinal cutting device 98 includes a threaded rod 981, which is movably sleeved inside the inclined sliding arm 99. A longitudinal sliding arm 982 is threadedly sleeved on the side wall of the threaded rod 981. A sliding groove penetrating into the interior is provided on one side of the inclined sliding arm 99. One end of the longitudinal sliding arm 982 passes through the sliding groove and is movably sleeved with a cutting blade 984 via a rotating column 983. The cutting blade 984 passes through a longitudinal cutting groove 913. The threaded rod 981 is driven to rotate by a servo motor 985, which is fixedly installed at one end of the inclined sliding arm 99. When the longitudinal cutting device 98 is running, the threaded rod 981 is driven to rotate by the servo motor 985. Under the influence of the threaded structure, the longitudinal sliding arm 982 moves longitudinally, thereby driving the cutting blade 984 to move longitudinally to cut the paper towel longitudinally.

[0036] Reference Figure 5 The cutter 984 is disc-shaped and rotates during the cutting process of the paper towel, which can prevent the paper towel from being pushed out of the wrinkles during the cutting process.

[0037] Reference Figure 4 The pressure plate 912 has several transverse grooves on one side that correspond to several transverse cutters 5. During the pressing process of the pressure plate 912, the transverse cutters 5 can be embedded in the transverse grooves to avoid the transverse cutters 5 blocking the pressing process of the pressure plate 912.

[0038] Reference Figure 6 The base platform 1 includes a main platform body 11. An electric cylinder 13 is installed at the bottom of the main platform body 11. The output shaft of the electric cylinder 13 is connected to the bottom of the stacking table 4. Several positioning posts 12 are set at the top of the main platform body 11. The tops of the positioning posts 12 penetrate the stacking table 4. An electric cylinder 2 14 is fixedly installed at the top of the main platform body 11. The output shaft of the electric cylinder 2 14 is connected to a pusher plate 15. Several slots corresponding to several transverse cutters 5 are set at the bottom of the pusher plate 15. When the base platform 1 is running, the electric cylinder 13 retracts and drives the stacking table 4 to move down to the bottom. Then, the output of the electric cylinder 2 14 drives the pusher plate 15 to move, so that the pusher plate 15 pushes out the folded paper towels at the top of the stacking table 4, thereby achieving the effect of unloading materials. By setting slots at the bottom of the pusher plate 15, the transverse cutters 5 can be prevented from forming a barrier on the pusher plate 15.

[0039] Reference Figure 7The counting mechanism 8 includes a pressure sensor 1 81, a pressure sensor 2 82, a controller, and a display screen. The pressure sensor 1 81 and the pressure sensor 2 82 are fixedly installed on both sides of the inner wall of the fixed frame 7. The pressure sensor 1 81 and the pressure sensor 2 82 are electrically connected to the controller, and the display screen is electrically connected to the controller. When the self-cleaning folding mechanism 6 operates to fold the paper towel, the end block 62 moves back and forth, thereby intermittently exerting pressure on the pressure sensor 1 81 and the pressure sensor 2 82. When the pressure sensor 1 81 or the pressure sensor 2 82 detects a pressure value, a single fold of the paper towel is completed. The number of folds is counted by displaying the video, thereby achieving the counting effect.

[0040] Reference Figure 8 The counter-rotating drive mechanism 66 includes a U-shaped plate 661, inside which are two gears 663 meshing with each other. A servo motor 662 is mounted on the back of the U-shaped plate 661. The output end of the servo motor 662 passes through the U-shaped plate 661 and is connected to a single gear 663. The two gears 663 are respectively connected to one end of the two conveying rollers 63. The servo motor 662 drives one gear 663 to rotate. According to their meshing relationship, the two gears 663 rotate in opposite directions, thereby causing the two conveying rollers 63 to rotate in opposite directions.

[0041] Reference Figure 9 The reciprocating drive mechanism 61 includes a track 611, a slider 612 slidably sleeved on the top of the track 611, the top of the slider 612 being fixedly connected to the end block 62, two end plates 613 being fixedly connected to the front of the track 611, a reciprocating lead screw 614 being movably sleeved on the inner side of the two end plates 613, a sleeve 616 being threadedly sleeved on the side wall of the reciprocating lead screw 614, the top of the sleeve 616 being fixedly connected to the end block 62, a servo motor 615 being fixedly installed on one side of the end plate 613, the output shaft of the servo motor 615 passing through the end plate 613 and connected to the reciprocating lead screw 614, the servo motor 615 driving the reciprocating lead screw 614 to rotate, and the sleeve 616 reciprocating laterally under the effect of the reciprocating thread structure, thereby achieving the effect of controlling the reciprocating lateral movement of the end block 62. By setting the slider 612 and the track 611, the stability of the end block 62 during movement can be improved.

[0042] The working principle of this invention is as follows: During use, the counter-rotating drive mechanism 66 drives the two conveying rollers 63 to rotate in opposite directions. When the tissue is between the two conveying rollers 63, it can be output downwards. During this process, the two reciprocating drive mechanisms 61 drive the two end blocks 62 to move laterally back and forth, so that when the two conveying rollers 63 output the tissue downwards, they simultaneously move left and right, thereby achieving a folding effect on the top of the stacking table 4. The centrifugal fan operates to draw air from the three-way pipe 67, creating a negative pressure inside the two dust collection hoods 64, thereby creating an adsorption effect on the side wall of the conveying rollers 63. This absorbs the dust on the side wall of the conveying rollers 63, achieving a self-cleaning effect. The two L-shaped air duct plates 65 can shield the area above the conveying rollers 63 to prevent dust from falling. At the same time, since the two L-shaped air duct plates 65 are connected to the two dust collection hoods 64, when the tissue passes between the two L-shaped air duct plates 65, a dust collection effect can be achieved on the surface of the tissue.

[0043] In the initial state, the two auxiliary arm assemblies 9 are in a downward pressing state, which can tighten the folded edge of the paper towel. When the self-cleaning folding mechanism 6 operates and forms a mechanical linkage with one of the auxiliary arm assemblies 9, the auxiliary arm assembly 9 can be automatically raised to prevent the paper towel from piling up on the auxiliary arm assembly 9. When the self-cleaning folding mechanism 6 operates and is disengaged from the auxiliary arm assembly 9, the paper towel is repressed by the auxiliary arm assembly 9. At this time, under the pressure, the paper towel comes into contact with several transverse cutters, thereby achieving a cutting effect.

[0044] During the reciprocating horizontal movement of the two end blocks 62, the counting mechanism 8 can detect the number of reciprocating horizontal movements to obtain the number of times the tissue paper covers the surface. Based on the production process, the number of times a single tissue paper is folded can be set. The total number of folds detected can be used to calculate the number of tissue paper, thus achieving the counting effect.

[0045] Once the tissues are folded to a certain number of layers, the folded tissues can be output through the base plate 1, completing the automatic unloading and thus saving manpower.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The present invention is not limited to the above embodiments; the embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this invention is defined by the appended claims and their equivalents.
