Description

Technical Field

[0001] The present invention belongs to the technical field of paper packaging machines, and particularly relates to a packaging paper tape conveying mechanism for a facial tissue packaging machine. Background Art

[0002] Facial tissues are also called boxed tissues, paper tissues, boxed facial tissues, tissue papers, etc. To avoid waste, they are divided into square or rectangular shapes, stacked on top of each other, and then placed in a paper box with a small opening. Each time, one sheet can be drawn out from the small opening, and another sheet will be brought out, hence the name "facial tissue".

[0003] In the early stage of facial tissue manufacturing, the papers are usually stacked into a long strip, and then a packaging paper tape is used by a paper packaging machine to package the long strip of facial tissues. Subsequently, it is cut into small segments, and after removing the packaging paper tape, it is placed in a facial tissue box for convenient use. In the design of the paper packaging machine, since the width dimension of the packaging paper tape for packaging the long strip of facial tissues is large, and the distance from the cutting position to the dropping terminal at the bottom of the packaging paper tape is long, the design of the conveying mechanism needs to be comprehensively considered. In particular, it is difficult for the packaging paper tape to smoothly drop from the cutting position to the terminal. Summary of the Invention

[0039] As Figure 1-17As shown, a packaging paper belt conveying mechanism of a paper-pulling packaging machine includes a frame 1, a paper supporting device is arranged inside the frame 1, a paper feeding and cutting device is arranged above the paper supporting device, and a lifting device 2 for adjusting the up and down movement of the paper feeding and cutting device is arranged above the paper feeding and cutting device.

[0040] With this design, the cutting position of the packaging paper strip 10 can be adjusted by the lifting device 2, so that the packaging paper strips 10 of different lengths can be cut conveniently, thereby packaging paper strips of different specifications.

[0041] The frame 1 is formed by splicing aluminum profiles.

[0042] The paper feeding and cutting device comprises a first wall panel 3 and a second wall panel 4 which are arranged in parallel at a certain distance. A paper feeding device 5 and a cutting device 6 are arranged between the first wall panel 3 and the second wall panel 4 . The cutting device 6 is located below the paper feeding device 5 .

[0043] The paper supporting device includes a lower paper supporting assembly 7, which is fixedly mounted on the frame 1. An upper paper supporting assembly 8 is arranged above the lower paper supporting assembly 7. Adjustment assemblies 9 for adjusting the upper paper supporting assembly 8 to be close to or away from the lower paper supporting assembly 7 are arranged at both ends of the lower paper supporting assembly 7.

[0044] The lifting device 2 includes two lifting support plates 201, which are fixedly connected to the frame 1 and are respectively arranged above the first wall panel 3 and the second wall panel 4. A screw lifting type worm gear screw lift 202 is arranged on the two lifting support plates 201.

[0045] The screw lifting type worm gear screw lift 202 is a prior art and can be purchased from the market.

[0046] The lifting support plate 201 is slidably connected with a first guide rod 203 at the positions on both sides of the screw-lifting type worm gear screw lift 202. The bottom end of the first guide rod 203 is fixedly connected to the corresponding first wall panel 3 or second wall panel 4. The bottom end of the screw of the screw-lifting type worm gear screw lift 202 is hinged to the corresponding first wall panel 3 or second wall panel 4, which is conducive to eliminating the installation error of the screw-lifting type worm gear screw lift 202.

[0047] In addition to this embodiment, the bottom end of the screw of the screw lifting type worm gear screw lift 202 can also be fixedly connected to the corresponding first wall panel 3 or second wall panel 4.

[0048] A transmission shaft 204 is connected between the two screw-lifting worm-gear screw jacks 202 , and a first hand wheel 206 is provided on any one of the screw-lifting worm-gear screw jacks 202 .

[0049] With this design, the first hand wheel 206 can be turned to facilitate the adjustment of the upper and lower positions of the paper feeding and cutting device.

[0050] A first paper guide roller 205 is rotatably connected to the transmission shaft 204.

[0051] The paper feeding device 5 includes a driving roller assembly 501. A first driven roller assembly 502 and a second driven roller assembly 503 are respectively arranged on two sides of the driving roller assembly 501. A paper guide roller assembly 505 is arranged above the driving roller assembly 501. A paper blocking assembly 504 is arranged between the driving roller assembly 501 and the second driven roller assembly 503.

[0052] With such a design, the first driven roller assembly 502 and the second driven roller assembly 503 respectively act with the driving roller assembly 501 to convey the packaging paper tape 10, and the conveying effect is good. The packaging paper tape 10 is not prone to wrinkles. The packaging paper tape 10 passes through the paper blocking assembly 504, ensuring smoother conveying.

[0053] The driving roller assembly 501 includes a driving shaft 5011. The driving shaft 5011 is rotatably connected to the first wallboard 3 and the second wallboard 4 through a mounting seat. A driving roller 5012 is fixedly sleeved on the driving shaft 5011. A plurality of first avoiding grooves 5013 are formed in the driving roller 5012.

[0054] A first motor 5014 is installed on the first wallboard 3. The output end of the first motor 5014 is in transmission connection with the driving shaft 5011.

[0055] The first driven roller assembly 502 includes two rocker arm seats 5021. The two rocker arm seats 5021 are respectively rotatably connected to the first wallboard 3 and the second wallboard 4. A first driven roller 5022 is rotatably connected between the two rocker arm seats 5021. First air cylinders 5023 are respectively hinged on the first wallboard 3 and the second wallboard 4. The telescopic rods of the first air cylinders 5023 are hinged to their corresponding rocker arm seats 5021.

[0056] With such a design, when the first air cylinder 5023 acts, it is convenient to drive the first driven roller 5022 to approach or move away from the driving roller 5012, so as to conveniently and effectively convey the packaging paper tape 10.

[0057] The second driven roller assembly 503 includes two sliders 5034. The two sliders 5034 are respectively slidably connected to the first wallboard 3 and the second wallboard 4. A driven shaft 5031 is fixedly connected between the two sliders 5034. A second driven roller 5032 is rotatably connected to the driven shaft 5031. A plurality of second avoiding grooves 5033 are formed in the second driven roller 5032.

[0058] Fixed stoppers 5035 are respectively fixedly connected to the first wallboard 3 and the second wallboard 4. A spring 5036 is arranged between the fixed stopper 5035 and its corresponding slider 5034. Two ends of the spring 5036 are respectively fixedly connected to the fixed stopper 5035 and the slider 5034.

[0059] With such a design, under the elastic force of the spring 5036, the second driven roller 5032 is pressed against the driving roller 5012, thereby effectively conveying the packaging paper tape 10.

[0060] The paper blocking assembly 504 includes a paper blocking plate 5041.

[0061] On one side of the paper blocking plate 5041 close to the second driven roller 5032, two support bars 5042 are fixedly connected through a spacer ring. On one side of the two support bars 5042 close to the paper blocking plate 5041, a plurality of paper blocking blocks 5043 are fixedly connected. The plurality of paper blocking blocks 5043 are arranged corresponding to the plurality of second avoidance grooves 5033.

[0062] With such a design, the packaging paper tape 10 passes between the paper blocking plate 5041 and the plurality of paper blocking blocks 5043, playing a good guiding role for the packaging paper tape 10.

[0063] The paper guiding roller assembly 505 includes a paper guiding shaft 5051. The paper guiding shaft 5051 is fixedly connected between the first wallboard 3 and the second wallboard 4. A second paper guiding roller 5052 is rotatably connected to the paper guiding shaft 5051.

A cutting knife 606 is fixedly connected to the cutting knife shaft 604 through a plurality of pressing knife blocks 605.

[0066] Adjusting screws for adjusting the positions of the sliding seats 603 are threadedly connected to positions on both sides of the sliding seats 603 on the first wallboard 3 and the second wallboard 4. By adjusting the positions of the sliding seats 603 through the adjusting screws, the relative positions of the cutting knife shaft 604 and the cutting knife 606 and the fixed knife 602 can be further adjusted.

[0067] The cutting knife 606 is installed on the cutting knife shaft 604 in a spiral shape, so that when the cutting knife 606 cooperates with the fixed knife 602 to cut the packaging paper tape 10, it is a point contact rather than a line contact, making the cutting more labor-saving, the cutting effect better, and it is not easy to produce wrinkles at the cutting place.

[0068] A second motor 607 is installed on the first wallboard 3. The output end of the second motor 607 is in transmission connection with the cutting knife shaft 604.

[0070] On one side of the paper blocking plate 5041 away from the paper blocking blocks 5043, a second air blowing pipe 5047 is fixedly connected through a plurality of first support blocks 5046. The second air blowing pipe 5047 is communicated with the air source, and a plurality of second air blowing holes are formed in the second air blowing pipe 5047.

[0071] A plurality of air passing grooves 5048 are formed in the bottom end of the paper blocking plate 5041, and the plurality of air passing grooves 5048 are arranged corresponding to the plurality of second air blowing holes.

[0072] With such a design, the air blown out from the first air blowing holes blows onto the packaging paper tape 10, avoiding the packaging paper tape 10 from adhering to the cutting knife shaft 604 and affecting the transmission of the packaging paper tape 10; the air blown out from the second air blowing holes blows onto the packaging paper tape 10 through the air passing grooves 5048, avoiding the packaging paper tape 10 from adhering to the fixed knife 602 and affecting the transmission of the packaging paper tape 10, and the air blown out from the first air blowing holes forms an air flow, which together with the fixed knife seat 601 forms a first channel. The packaging paper tape 10 is guided through the first channel, ensuring the smooth downward movement of the packaging paper tape 10.

[0073] Four first paper guiding plates 608 are fixedly connected to the bottom surface of the fixed knife seat 601, and the cross section of the first paper guiding plates 608 is in an "L" shape structure.

[0074] Except for this embodiment, the number of the first paper guiding plates 608 can also be one, two, three or more than four.

[0075] A third air blowing pipe 610 is fixedly connected between the first wallboard 3 and the second wallboard 4 through a connecting frame 609. The third air blowing pipe 610 is communicated with the air source, and a plurality of third air blowing holes are formed in the third air blowing pipe 610, and the third air blowing holes are formed at the bottom of the third air blowing pipe 610.

[0076] With such a design, the air blown out from the third air blowing holes forms an air flow, which together with the first paper guiding plates 608 forms a second channel.

[0078] The support frame 701 is formed by splicing aluminum profiles.

[0079] The flap assembly includes four support seats 705 fixedly connected to the bottom surface of the support plate 703. A swing shaft 706 is rotatably connected within the four support seats 705. Four first connection blocks 707 are fixedly connected to the swing shaft 706. A flap 704 is fixedly connected to the ends of the four first connection blocks 707 away from the swing shaft 706. The flap 704 is correspondingly arranged with the flap hole formed on the support plate 703.

[0080] With such a design, when the flap 704 is flipped into the flap hole, the support plate 703 and the flap 704 jointly play a role in supporting the paper towel strip. A gap through which the packaging paper tape 10 passes is formed between the flap 704 and the support plate 703.

[0084] Except for this embodiment, the number of the second connection blocks 806 and the guide rail slider assembly can also be two, three or more than four. The guide rail slider assembly is a prior art and can be purchased from the market.

[0085] A third support block 807 is fixedly connected to the position on the top surface of the positioning plate 801 on one side of the second support block 805. Second air cylinders 808 are installed at positions near both ends of the third support block 807. The telescopic rods of the second air cylinders 808 are hinged to the second support block 805, which is beneficial to eliminating the installation error of the second air cylinders 808.

[0086] Except for this embodiment, the telescopic rods of the second air cylinders 808 can also be fixedly connected to the second support block 805.

[0087] The third support block 807 is processed from aluminum profiles.

[0088] On the top surface of the positioning plate 801, at a position on one side of the paper passing hole 803, a fourth support block 809 is fixedly connected. On the top surface of the fourth support block 809, four second paper guide plates 810 are fixedly connected. The second paper guide plates 810 and the first paper guide plate 608 together form a guiding surface of the second channel.

[0089] With such a design, the second air cylinder 808 drives the paper guiding block 804 and the second support block 805 away from the fourth support block 809, facilitating the packaging paper tape 10 to pass through the paper passing hole 803.

[0090] Except for this embodiment, the number of the second paper guide plates 810 can also be one, two, three or more than four.

[0091] On the side surface of the fourth support block 809 close to the positioning plate 801, a first air chamber groove 8091 is formed. The first air chamber groove 8091 and the top surface of the positioning plate 801 together form a first air chamber, which is communicated with the air source. At the position of the positioning plate 801 close to the paper passing hole 803, a plurality of fourth air blowing holes 8011 are formed, and the fourth air blowing holes 8011 are communicated with the first air chamber.

[0092] On the side surface of the second support block 805 close to the paper guiding block 804, a second air chamber groove 8051 is formed. The second air chamber groove 8051 and the top surface of the paper guiding block 804 together form a second air chamber, which is communicated with the air source. On the paper guiding block 804, a plurality of fifth air blowing holes 8041 are formed, and the fifth air blowing holes 8041 are communicated with the second air chamber.

[0093] With such a design, the air flows blown out from the fourth air blowing holes 8011 and the fifth air blowing holes 8041 form air walls on both sides of the packaging paper tape 10. A third channel is formed between the two air walls, which effectively guides the packaging paper tape 10 and ensures the smooth downward movement of the packaging paper tape 10.

[0094] The adjusting assembly 9 includes a third connecting block 901, the third connecting block 901 is fixedly connected with the support frame 701. A second guiding rod 902 is slidably connected in the third connecting block 901. A threaded rod 903 is threadedly connected in the third connecting block 901. The threaded rod 903 and the second guiding rod 902 are arranged in parallel. Above the third connecting block 901, a fourth connecting block 904 is provided. The fourth connecting block 904 is fixedly connected with the corresponding third support plate 802. The second guiding rod 902 is fixedly connected with the fourth connecting block 904. The threaded rod 903 is rotatably connected with the fourth connecting block 904. The top end of the threaded rod 903 passes through the fourth connecting block 904 and is fixedly connected with a second hand wheel 905.

[0095] With such a design, rotating the second hand wheel 905 facilitates adjusting the upper paper supporting assembly 8 to be close to or away from the lower paper supporting assembly 7, so that the paper strips of different specifications can conveniently pass through the cavity between the supporting plate 703 and the positioning plate 801 and enter the next process.

[0096] Finger-turning screws 906 are installed at both ends of the support frame 701. After adjusting the position of the upper paper supporting component 8 through the adjusting component 9, locking the finger-turning screws 906 can conveniently fix the third support plate 802 and the support frame 701 together, and further fasten the upper paper supporting component 8 and the lower paper supporting component 7 together.

[0097] During use, the packaging paper tape 10 coming from the paper feeding mechanism is wound around the first paper guiding roller 205, the first driven roller 5022, the driving roller 5012, the second paper guiding roller 5052 and the second driven roller 5032 as shown in Figure 3 the figure. The rotation of the driving roller 5012 drives the packaging paper tape 10 to move downward. The rational design of the first driven roller assembly 502 facilitates the packaging paper tape 10 to pass between the first driven roller 5022 and the driving roller 5012. The rational design of the second driven roller assembly 503 facilitates the packaging paper tape 10 to pass between the second driven roller 5032 and the driving roller 5012. The rational design of the paper blocking component 504 facilitates the packaging paper tape 10 to pass between the paper blocking plate 5041 and the multiple paper blocking blocks 5043, playing a good guiding role for the packaging paper tape 10.

[0098] The packaging paper tape 10 continues to move downward through the first channel and the second channel. When the packaging paper tape 10 passes through the paper passing hole 803, the paper guiding block 804 and the second support block 805 move away from the fourth support block 809, facilitating the packaging paper tape 10 to pass through the paper passing hole 803.

[0099] The packaging paper tape 10 continues to move downward through the third channel. When the packaging paper tape 10 passes through the flap hole, the flap 704 moves away from the flap hole, increasing the space for the packaging paper tape 10 to pass through the flap hole and facilitating the packaging paper tape 10 to pass through the flap hole.

[0100] When the packaging paper tape 10 reaches the specified position, the flap 704 swings to block the flap hole and jointly forms a supporting surface with the support plate 703, facilitating the effective support for the paper towel strip pushed from the conveyor belt mechanism. At this time, the paper guiding block 804 and the second support block 805 also move and approach the fourth support block 809, leaving only a gap for the packaging paper tape 10 to pass through.

[0101] Then, the cutting knife shaft 604 rotates and drives the cutting knife 606 to act. The cutting knife 606 cooperates with the fixed knife 602 to cut the packaging paper tape 10. The pushing mechanism pushes the packaging paper tape 10 and the paper towel strip to the next process for paper pressing and heat sealing. During the process of the packaging paper tape 10 and the paper towel strip passing through the cavity between the support plate 703 and the positioning plate 801, through the limitation of the support plate 703 and the positioning plate 801, the packaging paper tape 10 effectively wraps the front, top and bottom surfaces of the paper towel strip during its advancement.

[0102] Embodiment 2:

[0103] Four air blowing plates 611 are fixedly connected to the bottom surface of the fixed tool holder 601. The air blowing plates 611 replace the first guide paper board 608 and jointly form a second channel with the air flow blown out from the third air blowing holes, ensuring the smooth downward movement of the packaging paper tape 10.

[0104] Except for this embodiment, the number of the air blowing plates 611 can also be one, two, three or more than four.

[0105] Such as Figure 18 shown, two air blowing components are arranged on the air blowing plate 611.

[0106] Except for this embodiment, the number of the air blowing components can also be one or more than two.

[0107] The air blowing component includes an air cavity 6111 opened in the air blowing plate 611. The air cavity 6111 is communicated with an air source. An air outlet surface 6112 and a air guiding surface 6114 are arranged on one side of the air blowing plate 611 close to the third air blowing pipe 610. A plurality of sixth air blowing holes 6113 are opened on the air outlet surface 6112. The sixth air blowing holes 6113 are communicated with the air cavity 6111.

[0108] With such a design, the air flow blown out from the sixth air blowing holes 6113 and the air flow blown out from the third air blowing holes jointly form a second channel. The packaging paper tape 10 is guided through the second channel, ensuring the smooth downward movement of the packaging paper tape 10.

[0109] A plurality of air leakage holes 6115 are opened on the air guiding surface 6114.

[0110] With such a design, when the air flow blown out from the sixth air blowing holes 6113 is too large, it can be discharged from the air leakage holes 6115, so that the air flow on both sides of the packaging paper tape 10 is more balanced and stable, further ensuring the smooth downward movement of the packaging paper tape 10.

[0111] For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, the changes, modifications, substitutions and variations made to the embodiments still fall within the protection scope of the present invention.
