[0025] Please refer to Figures 1-10 , the embodiments of the present invention provide a technical solution: a paper towel cutting and conveying device, including a conveying frame 1, a U-shaped frame 5 is fixedly installed in the middle of the top wall of the conveying frame 1, a cutting assembly 6 is installed on the top wall of the U-shaped frame 5, a leveling assembly 7 is fixedly installed on the left side wall of the cutting assembly 6, a lifting assembly 8 is installed on the outer wall of the conveying frame 1, a pushing assembly 9 is installed on the inner wall of the conveying frame 1, a placing frame 2 is installed on the left side of the top wall of the conveying frame 1, a U-shaped seat 3 is fixedly installed on the top wall of the conveying frame 1, and a conveying roller 4 is rotatably installed in the inner wall of the U-shaped seat 3; The cutting assembly 6 includes an electric push rod 61, the electric push rod 61 is fixedly connected to the top wall of the U-shaped frame 5, the movable end of the electric push rod 61 slidably penetrates through the U-shaped frame 5 and is fixedly installed with a lifting seat 62, a cutting knife 65 is fixedly installed on the bottom wall of the lifting seat 62, and a knife groove 66 is opened on the top wall of the conveying frame 1 corresponding to the position of the cutting knife 65; Installation plates 614 are fixedly installed on the outer side walls of the lifting seat 62, a plurality of high-precision measuring instruments 67 are fixedly installed on the side walls of the installation plates 614 on the right side, installation cylinders 68 are fixedly installed on the outer side walls of the two installation plates 614, installation cavities 69 are opened in the inner walls of the plurality of installation cylinders 68, abutting springs 610 are installed in the inner walls of the plurality of installation cavities 69, sliding seats 611 are slidably installed at the bottom ends of the plurality of abutting springs 610, sliding rods 612 are fixedly installed at the bottom ends of the plurality of sliding seats 611, and rubber pads 613 are fixedly installed at the bottom ends of the plurality of sliding rods 612.

[0026] In this implementation scheme, when cutting the paper towel, it is possible to abut and fix the left and right sides of the cutting position of the paper towel to prevent the paper towel from wrinkling after being stressed during cutting. The sliding rod 612 and the rubber pad 613 can increase the friction with the paper towel to prevent misalignment problems. At the same time, the cutting length of the paper towel is limited to reduce material loss problems. When the high-precision measuring instrument 67 measures the discharged length of the diameter, the external controller controls the conveying roller 4 to stop working.

[0027] Specifically, limit sliders 63 are fixedly installed on both the front and rear walls of the lifting seat 62. Limit sliding grooves 64 are provided on both the front and rear walls of the U-shaped frame 5 at positions corresponding to the limit sliders 63. The inner walls of the two limit sliding grooves 64 are slidably connected to the outer walls of the corresponding limit sliders 63. Both limit sliders 63 are fixedly connected to the lifting assembly 8. A number of mounting cylinders 68 are in an "L" shape, and the outer walls of a number of sliding seats 611 are slidably connected to the inner wall of the mounting cavity 69.

[0028] In this implementation scheme, the limit slider 63 slides in the inner wall of the limit sliding groove 64 mainly to limit the position of the lifting seat 62 and prevent the position from shifting during the up and down movement.

[0029] Specifically, the leveling assembly 7 includes a U-shaped platform 71. The U-shaped platform 71 is fixedly connected to the left mounting plate 614. Limit seats 72 are fixedly installed on both the front and rear walls of the U-shaped platform 71. Positioning rods 73 are installed at the tops of the two limit seats 72. The bottom ends of the two positioning rods 73 slidably penetrate through the corresponding limit seats 72 and are fixedly installed with the same L-shaped frame 75. Support springs 74 are sleeved and installed on the top wall of the L-shaped frame 75 at positions corresponding to the positioning rods 73. The top ends of the two support springs 74 are fixedly connected to the bottom wall of the corresponding limit seats 72.

[0030] In this implementation scheme, the setting of the support spring 74 and the positioning rod 73 mainly serves to support and limit the L-shaped frame 75.

[0031] Specifically, a leveling roller 76 is rotatably installed on the inner wall of the L-shaped frame 75, and a scraping plate 77 is fixedly installed on the side wall of the L-shaped frame 75.

[0032] In this implementation scheme, the leveling roller 76 and the scraping plate 77 can scrape and roll-press the possible wrinkles on the surface of the conveyed paper towels to make its surface flat and prevent the cutting misalignment problem.

[0033] Specifically, the lifting assembly 8 includes two connecting blocks 81 arranged symmetrically in the front and rear. Both connecting blocks 81 are fixedly connected to the corresponding limit sliders 63. Tooth plates 82 are fixedly installed on the mutually remote sides of the two connecting blocks 81. A trapezoidal seat 83 is fixedly installed on the rear wall of the tooth plate 82. A trapezoidal groove 811 is opened in the middle of the outer wall of the conveying frame 1. The inner walls of the two trapezoidal grooves 811 are slidably connected to the outer walls of the corresponding trapezoidal seats 83.

[0034] In this implementation scheme, when the limit slider 63 moves, it will drive the connecting block 81 and the tooth plate 82 to move. The tooth plate 82 drives the trapezoidal seat 83 to slide in the inner wall of the trapezoidal groove 811, which can limit the movement track of the tooth plate 82 and prevent the problem of position deviation.

[0035] Specifically, a second trapezoidal groove 86 is formed on the right side of the outer wall of the conveying frame 1. Two second trapezoidal seats 88 are slidably installed on the inner walls of the two second trapezoidal grooves 86. A second toothed plate 87 is fixedly installed on the side of each of the two second trapezoidal seats 88 away from each other. A same receiving seat 89 is fixedly installed at the bottom of the two second toothed plates 87.

[0036] In this implementation, the second toothed plate 87 drives the second trapezoidal seat 88 to slide on the inner wall of the second trapezoidal groove 86, which can limit the movement track of the second toothed plate 87, so that it can accurately mesh and drive with the transmission gear 85, and the second toothed plate 87 will drive the receiving seat 89 to move up and down when it moves.

[0037] Specifically, rotating shafts 84 are rotatably installed on the front and rear walls of the conveying frame 1. The two rotating shafts 84 are fixedly connected to the pushing assembly 9. Transmission gears 85 are fixedly installed on the outer walls of the two rotating shafts 84. The two transmission gears 85 are meshed and connected with the corresponding first toothed plates 82 and second toothed plates 87 respectively. A through port 810 is formed on the right side of the top wall of the conveying frame 1 corresponding to the position of the receiving seat 89.

[0038] In this implementation, the movement of the first toothed plate 82 will drive the transmission gear 85 to rotate, and then drive the second toothed plate 87 to move up and down. At the same time, the transmission gear 85 and the rotating shaft 84 will drive the pushing assembly 9 to work in cooperation when rotating.

[0039] Specifically, the pushing assembly 9 includes an installation table 91. The bottom wall of the installation table 91 is fixedly connected to the inner wall of the conveying frame 1. First supports 92 are fixedly installed at the front and rear parts of the top wall of the installation table 91. A transmission rod 93 is rotatably installed on the adjacent sides of the two first supports 92. First synchronous wheels 99 are fixedly installed at the front and rear ends of the transmission rod 93. A first bevel gear 94 is fixedly installed on the outer wall of the transmission rod 93. Second synchronous wheels 910 are fixedly installed on the outer walls of the two rotating shafts 84. The two second synchronous wheels 910 are connected by a synchronous belt to the corresponding first synchronous wheels 99 for transmission.

[0040] In this implementation, when the rotating shaft 84 rotates, it will drive the first synchronous wheel 99, the synchronous belt and the second synchronous wheel 910 to transmit, and then drive the transmission rod 93 and the first bevel gear 94 to rotate between the first supports 92.

[0041] Specifically, second supports 96 are arranged symmetrically on the left and right of the top wall of the installation table 91. An adjusting screw rod 97 is rotatably installed on the adjacent sides of the two second supports 96. The left end of the adjusting screw rod 97 passes through the corresponding second support 96 through a bearing and is fixedly installed with a second bevel gear 95. The second bevel gear 95 is meshed with the first bevel gear 94.

[0042] In this implementation, when the first bevel gear 94 rotates, it will drive the second bevel gear 95 and the adjusting screw rod 97 to rotate between the second supports 96.

[0043] Specifically, a sliding seat 98 is screwed and installed on the outer wall of the adjusting lead screw 97. A moving frame 911 is fixedly installed on the top wall of the sliding seat 98. Push plates 912 are hinged and installed on the front and rear walls on the right side of the moving frame 911. A collection box 913 is fixedly installed on the right side inside the conveying frame 1.

[0044] In this implementation scheme, when the adjusting lead screw 97 rotates, it will drive the sliding seat 98 to slide along the top wall of the conveying frame 1, which can prevent the sliding seat 98 from flipping, and simultaneously drive the moving frame 911 and the push plate 912 to move, so as to push the cut paper towels on the receiving seat 89 into the inner wall of the collection box 913 for placement, and collect the paper towels uniformly.

[0045] Working principle: Electric push rod 61 and high-precision measuring instrument 67 are electrically connected through an external power supply and a controller. When officially working, first place the paper towel roller on the placing rack 2, and pass the movable end through the conveying roller 4 inside the U-shaped seat 3, so that the conveying roller 4 can electrically convey the paper towel to the bottom position of the cutting assembly 6. When the paper towel gradually moves to the right on the top wall of the conveying frame 1, the high-precision measuring instrument 67 is used to monitor the moving length of the paper towel in real time. The electric push rod 61 is used to push the lifting seat 62 to slide downward inside the U-shaped frame 5. The lifting seat 62 drives the U-shaped table 71 and the limiting seat 72 to move downward. When the limiting seat 72 drives the positioning rod 73 and the L-shaped frame 75 to move downward, the L-shaped frame 75 drives the flattening roller 76 and the scraping plate 77 to move downward and gradually contact the paper towel. The scraping plate 77 can scrape the possible wrinkles on the surface of the paper towel flat, and after being roll-pressed by the flattening roller 76, the surface of the paper towel becomes smoother. When the L-shaped frame 75 continues to move downward, it will compress the support spring 74 to drive the positioning rod 73 to slide upward inside the limiting seat 72. The support spring 74 mainly plays a role in connecting and supporting between the limiting seat 72 and the L-shaped frame 75; The lifting seat 62 drives the limiting slider 63 to slide downward inside the corresponding limiting chute 64, so that when the lifting seat 62 moves downward, it will drive the mounting plate 614 and the mounting cylinder 68 to move downward. The mounting cylinder 68 drives the sliding rod 612 and the rubber pad 613 to move downward. When the rubber pad 613 abuts against the paper towel in contact, when the lifting seat 62 drives the cutting knife 65 to continue to move downward, the rubber pad 613 and the sliding rod 612 are stressed and will drive the sliding seat 611 to slide inside the mounting cavity 69 and compress the abutting spring 610. At the same time, the cutting knife 65 enters the inner wall of the knife groove 66, and can cut the paper towel passing through the bottom of the cutting knife 65; When the limit slider 63 slides downward along the inner wall of the limit chute 64, it will drive the connecting block 81 and the first toothed plate 82 to move downward. The first toothed plate 82 drives the first trapezoidal seat 83 to slide downward along the inner wall of the first trapezoidal groove 811, which can limit the movement path of the first toothed plate 82 to prevent position deviation. When the first toothed plate 82 moves downward, it will drive the transmission gear 85 and the rotating shaft 84 meshed with it to rotate. After the transmission gear 85 rotates, it will drive the second toothed plate 87 and the second trapezoidal seat 88 to move upward. The second trapezoidal seat 88 slides upward along the inner wall of the second trapezoidal groove 86. After the second trapezoidal seat 88 moves upward, it will drive the receiving seat 89 to move upward and gradually pass through the through-hole 810 to be horizontal with the top wall of the conveying frame 1. When the cutting knife 65 starts to contact the paper towel, the receiving seat 89 enters the inner wall of the through-hole 810 and is horizontal with the top wall of the conveying frame 1. The cut paper towel falls on the top wall of the receiving seat 89; When the receiving seat 89 rises, the rotation of the rotating shaft 84 and the transmission gear 85 will drive the second synchronous pulley 910 and the synchronous belt to rotate. The synchronous belt drives the corresponding first synchronous pulley 99 to rotate. Then, the first synchronous pulley 99 drives the transmission rod 93 and the first bevel gear 94 to rotate. When the transmission rod 93 and the first bevel gear 94 rotate on the top wall of the mounting table 91, they will drive the meshing second bevel gear 95 to rotate. The second bevel gear 95 drives the adjusting screw rod 97 to rotate on the inner wall of the second support 96. Then, the sliding seat 98 drives the moving frame 911 and the pushing plate 912 to slide leftward along the outer wall of the adjusting screw rod 97; After the paper towel is cut, the movable end of the electric push rod 61 contracts to drive the leveling assembly 7 and the rubber pad 613 to rise back to the original position. Then, the limit slider 63 will drive the connecting block 81 and the first toothed plate 82 to move upward. The first toothed plate 82 drives the first trapezoidal seat 83 to slide upward along the inner wall of the first trapezoidal groove 811. When the first toothed plate 82 moves upward, it will drive the transmission gear 85 and the rotating shaft 84 meshed with it to rotate. After the transmission gear 85 rotates, it will drive the second toothed plate 87 and the second trapezoidal seat 88 to move downward. The second trapezoidal seat 88 slides downward along the inner wall of the second trapezoidal groove 86. After the second trapezoidal seat 88 moves downward, it will drive the receiving seat 89 to move downward and gradually disengage from the through-hole 810. Then, the cut paper towel slowly moves downward on the receiving seat 89; When the receiving seat 89 descends, the rotation of the rotating shaft 84 and the transmission gear 85 will drive the second synchronous pulley 910 and the synchronous belt to rotate. The synchronous belt drives the corresponding first synchronous pulley 99 to rotate. Furthermore, the first synchronous pulley 99 drives the transmission rod 93 and the first bevel gear 94 to rotate. When the transmission rod 93 and the first bevel gear 94 rotate on the top wall of the mounting table 91, they will drive the engaged second bevel gear 95 to rotate. The second bevel gear 95 drives the adjusting lead screw 97 to rotate on the inner wall of the second support 96. Furthermore, the sliding seat 98 drives the moving frame 911 and the push plate 912 to slide rightward along the outer wall of the adjusting lead screw 97. The cut tissue paper on the receiving seat 89 is pushed into the inner wall of the collection box 913 for placement by the push plate 912. Through the mutual cooperation and linkage of the above-mentioned various components, it is possible to continuously fix the left and right sides of the cutting position of the tissue paper, and at the same time scrape and roll the wrinkles of the diameter during the conveying process. After the tissue paper is cut, it is received and transferred, and after the transfer is completed, it is pushed out and collected uniformly.
