Description

Technical Field

[0001] The present invention belongs to the technical field of packaging paper production, and in particular relates to packaging paper production equipment with a self-cleaning function. Background Art

[0002] Wrapping paper is a general term for a type of paper used primarily for packaging. It typically possesses high strength and toughness, and is resistant to pressure and folding. Its quality requirements are simpler than those for other types of paper, such as cultural printing paper. There are many different types of paper, each with different properties and uses.

[0003] The current wrapping paper production process requires a large amount of mechanical equipment, such as rinsing the base paper and cutting and splitting the finished paper, which is mainly processed and produced by mechanical equipment. However, the following problems still exist in the wrapping paper production process: First, because the wrapping paper can only be used after cutting, the raw wrapping paper is often accompanied by dust and debris. When the wrapping paper is trimmed, the debris particles are easily squeezed by the cutting tool, causing indentations at the cut part of the wrapping paper below, damaging the integrity of the paper. The paper trimming process also produces a large amount of debris and scraps, which will affect the subsequent cutting. Second, the cut pieces of wrapping paper are directly scattered on the ground, and they need to be manually collected and compressed for recycling, which not only wastes manpower and material resources, but also affects recycling efficiency.

The second pulley 710, the inner side of the second pulley 710 is fixedly connected to the third driven pulley 711, the middle part of the third driven pulley 711 is fixedly connected to the third pressure roller 712 whose two ends are movably connected to the shell 2, the upper part of the third driven pulley 711 is meshed with the fourth driven pulley 713, the middle part of the fourth driven pulley 713 is fixedly connected to the fourth pressure roller 714 whose two ends are movably connected to the shell 2, the first guide rod 715 which is movably connected to the shell 2 is installed above the second pressure roller 708, the front of the first guide rod 715 is installed with the second guide rod 716 which is movably connected to the shell 2, the lower part of the second guide rod 716 is installed with the fourth guide rod 718 which is movably connected to the shell 2, and the rear part of the fourth guide rod 718 is installed with the third guide rod 717 which is movably connected to the shell 2.

[0048] Its function is to drive the first pressing roller 706, the second pressing roller 708, the third pressing roller 712, and the fourth pressing roller 714 to rotate through the motor, and drive the collecting rod 103 to rotate through the toothed belt 101.

[0049] Among them, the small driving gear 703 is engaged with a toothed belt 2 101, the middle part of the toothed belt 2 101 is engaged with a large driven wheel 102, the middle part of the large driven wheel 102 is fixedly connected to a collecting rod 103 movably connected to the shell 2, and a waste guide rod 104 fixedly connected to the shell 2 is installed between the collecting rod 103 and the third guide rod 717.

[0050] Its function is to allow the trimmed waste to pass through the third guide rod 717 and the waste guide rod 104, and the motor 701 drives the collection rod 103 to rotate, so that the waste is rotated and tightened on the collection rod 103. The waste on the collection rod 103 is collected to a certain extent and then removed.

[0051] In which, a cavity is opened in the middle of the shell 2, the threads on the threaded rod 81 are symmetrical about the center, the trimming mechanism 8 is installed between the second guide rod and the third guide rod, the cleaning mechanism 9 is installed between the third guide rod 717 and the fourth guide rod 718, and the waste collection mechanism 10 is installed below the third guide rod 717.

[0052] Its function is to increase the distance between the two trimming blades 83 by rotating the threaded rod 81 clockwise, and decrease the distance between the two trimming blades 83 by rotating the threaded rod 81 counterclockwise, so that the purpose of changing the trimming material width can be achieved by rotating the threaded rod 81.

[0053] The wide parts of the first pressing roller 706 , the second pressing roller 708 , the third pressing roller 712 , and the fourth pressing roller 714 are made of rubber.

[0054] Its function is to not damage the raw materials when the motor drives the first pressing roller 706, the second pressing roller 708, the third pressing roller 712, and the fourth pressing roller 714 to rotate, and to transmit the raw materials forward without slipping.

[0055] The opening direction of the one-way valve 95 is from the exhaust pipe 67 to the pipe head 92 , and the opening pressure of the one-way valve 95 is the pressure when the partition 63 moves down to the bottom.

[0056] Its function is that when the air pump 51 is working, it pumps air into the air storage chamber 53. When the pressure in the air storage chamber 53 is greater than the pressure required for the partition 63 to move down to the bottom, the one-way valve 95 is opened, and the compressed gas enters the tube body 91 through the compressed air pipe 94 and the pipe head 92, and then is discharged from the air outlet 93 on the tube body 91 to clean the raw materials; when the control valve 69 opens the air inlet pipe 61, the gas in the air storage chamber 53 enters the compression chamber 62 in a very short time and causes the partition 63 to move downward. In this process, only the opening size of the one-way valve 95 is changed, and gas still passes through the one-way valve 95.

[0057] Working principle and usage process:

[0058] Before use, the distance between the trimming blades 83 is controlled to the target width by adjusting the knob 82. The raw material is placed at the rear of the housing 2 and passed through the gap between the first pressing roller 706 and the second pressing roller 708. The raw material then passes through the first guide rod 715, the second guide rod 716, the third guide rod 717, the fourth guide rod 718, and the gaps between the third pressing roller 712 and the fourth pressing roller 714. During this process, the waste material, trimmed on both sides of the raw material, passes through the third guide rod 717 and the waste guide rod 104 and is fixed to the collection rod 103. The control panel 4 is controlled to operate the air pump 51 to pump air into the air storage chamber 53. When the pressure in the air storage chamber 53 causes the opening of the one-way valve 95 to be at its maximum position, and when compressed gas is discharged from the air outlet 93, the control panel 4 is controlled to operate the motor 701.

[0059] The output shaft of the motor 701 drives the large driving gear 702 and the small driving gear 703 clockwise, and the small driving gear 703 drives the large driven wheel 102 to rotate clockwise through the toothed belt 2 101, thereby driving the collecting rod 103 to rotate; the large driving gear 702 drives the meshing first driven wheel 704 to rotate counterclockwise, thereby driving the fixedly connected first pulley 705 and the first pressure roller 706 to rotate counterclockwise, the first driven wheel 704 drives the meshing second driven wheel 707 to rotate clockwise, thereby driving the second pressure roller 708 to rotate clockwise, the first pulley 705 drives the second pulley 710 to rotate counterclockwise through the toothed belt 1 709, thereby driving the fixedly connected third driven wheel 711 and the third pressure roller 712 to rotate counterclockwise, the third driven wheel 711 drives the meshing fourth driven wheel 713 to rotate clockwise, thereby driving the fourth pressure roller 714 fixedly connected to the fourth driven wheel 713 to rotate clockwise. When the first pressing roller 706 and the second pressing roller 708 rotate, the raw material is transmitted forward, passes through the trimming mechanism 8, and is trimmed into the target width by the trimming blade 83. The trimmed waste passes through the third guide rod 717 and the waste guide rod 104 and is tightly rolled up by the collecting rod 103.

[0060] When the trimmed material passes through the cleaning mechanism 9, the gas in the air storage chamber 53 enters the two tube bodies 91 through the air inlet pipe 61, the compressed air pipe 94, and the pipe head 92, and is discharged from the air outlet 93 on the two tube bodies 91. The compressed air cleans the trimmed material. The cleaned material is then transferred to the trimming table by the third and fourth pressure rollers 712 and 714. When the length of the raw material delivered is the target length, the control valve 69 is controlled to open the air inlet pipe 61 and close the exhaust pipe 67. The air in the air storage chamber 53 enters the compression chamber 62, thereby quickly pushing the partition 63 and the cutting blade 66 on the tool holder 65 to cut the target length of the raw material. During the process, the partition 63 compresses the compression spring 68. After the cutting is completed, the control panel 4 controls the control valve 69 to close the air inlet pipe 61 and open the exhaust pipe 67. The compression spring 68 returns to its original length upward. The partition 63 pushes the compressed gas in the compression chamber through the exhaust pipe 67 and the compression air pipe 94 and then enters the tube body 91. The gas is discharged from the air outlet 93 of the tube body 91 to clean the material. During the process, the cutting blade 66 returns to its initial position, and the cutting is repeated.
