Description

Technical Field

[0001] This utility model relates to the technical field of paper product manufacturing equipment, specifically a slitting device for paper product manufacturing. Background Technology

[0002] Paper products are various products made from raw materials such as pulp, paperboard, and paper through processing. During the processing of paper products, a slitting machine is needed to cut the paper into strips. The principle of the slitting machine is to use a cutting blade to cut wide paper or film into multiple narrow strips, which makes it easier to process the paper. Traditional paper product slitting equipment cannot assist in adsorbing the paper. When the gap between the paper and the conveyor surface is large, the paper is prone to shaking or warping, resulting in uneven slitting in the later stages.

[0003] For example, the authorized patent document with application number CN202420124443.0 discloses an automatic slitting machine for paper product production, which includes a base, a support frame on the top of the base, support plates on both sides of the support frame, and a slitting frame electric push rod on the top of each support plate. The output end of each slitting frame electric push rod is provided with a limit block. In the above structure, the paper product slitting equipment cannot perform auxiliary adsorption of the paper, that is, there is a large gap between the paper and the conveying surface, which makes the paper prone to shaking or warping, resulting in uneven slitting in the subsequent process. Therefore, we need to provide a slitting device for paper product production. Utility Model Content

[0027] The adsorption guiding mechanism 3 includes a mechanical pressing member 31 and a flexible adsorption member 32. The mechanical pressing member 31 is installed in the frame 1 and is used for paper conveying and rigid pressing. The flexible adsorption member 32 is located below the mechanical pressing member 31 and is used for auxiliary adsorption of paper to reduce the gap between the paper and the conveying surface.

[0028] Specifically, a cutter 2 is installed on the surface of the frame 1 to cut the paper, and an adsorption and guiding mechanism 3 is provided to press and guide the paper, while also adsorbing the paper to reduce the gap between the paper and the conveying surface.

[0029] The mechanical holding component 31 and the flexible adsorption component 32 of the adsorption guiding mechanism 3 cooperate with each other to form a paper processing mode that combines rigidity and flexibility. The mechanical holding component 31, through the cooperation of the drive roller 312 and the pressure roller 313, ensures that the paper does not deviate or slip during the conveying process with rigid pressure, providing a stable foundation for slitting. The flexible adsorption component 32 forms negative pressure adsorption by exhaust, and utilizes the structure of the air hole 322 and the air frame 323 to effectively reduce the gap between the paper and the conveying surface, avoid problems such as wrinkles and shaking caused by the paper being suspended, and ensure slitting accuracy.

[0030] The flexible adsorption component 32 includes a plate 321, air holes 322, an air frame 323, and an exhaust component 324. The plate 321 is embedded in the frame 1, with one side flush with the surface of the frame 1. Multiple air holes 322 are provided inside the plate 321. An exhaust component 324 is installed on one side of the plate 321 through the air frame 323. The exhaust component 324 is used to extract air from the air frame 323.

[0031] Furthermore, the plate 321 is made of hard aluminum alloy and is embedded in the frame 1 through an inlay process. One side of it is flush with the surface of the frame 1 to form a smooth paper conveying surface. Multiple air holes 322 with a diameter of 3mm are evenly opened inside the plate 321. The air holes 322 are distributed in a honeycomb pattern to ensure uniform adsorption force. One side of the plate 321 is fixedly connected to the air frame 323 by bolts. The air frame 323 is made of stainless steel and has good sealing and corrosion resistance. An exhaust component 324 is installed on one side of the air frame 323. The exhaust component 324 is used to extract the air inside the air frame 323 and form a negative pressure on the surface of the plate 321 to adsorb the paper.

[0032] The exhaust component 324 includes a frame 3241, a fan 3242, and a protective net 3243. The frame 3241 is connected to the air frame 323 and has three fans 3242 installed inside. The air outlet of the fans 3242 is facing upward, and the protective net 3243 is installed at the air outlet of the fans 3242.

[0033] It is worth noting that the frame 3241 is made of PVC engineering plastic in one piece and is sealed to the air frame 323 to ensure airtightness. Three axial flow fans 3242 are installed at equal intervals inside the frame 3241. The fans 3242 have a power of 30W and a speed of 1500r / min. The air outlet is located facing upwards, which can quickly exhaust the air in the air frame 323. A metal protective net 3243 is fixedly installed at the air outlet of the fans 3242 with screws. The protective net 3243 can prevent foreign objects from entering and damaging the fans 3242 without affecting the exhaust efficiency.

[0034] A spoiler 4 is fixedly installed inside the air frame 323, and the spoiler 4 is located at the air inlet of the frame 3241;

[0035] It should be noted that the baffle 4 is made of a corrugated stainless steel plate, located at the air inlet of the air frame 323 and connected to the air hole 322 of the plate body 321. The corrugated design of the baffle 4 can extend the airflow path at the center of the plate body 321, making the negative pressure suction on the surface of the plate body 321 more uniform, effectively avoiding the problem of wrinkles caused by insufficient or excessive local adsorption of paper.

[0036] A baffle plate 5 is fixedly installed between the air frame 323 and the stand 1, and a filter plate 6 is slidably installed inside the air frame 323.

[0037] Among them, the wind deflector 5 is a transparent acrylic plate used to block the air from the fan 3242 from blowing onto the paper; a filter plate 6 is slidably installed inside the air frame 323. The filter plate 6 has a detachable structure and uses an activated carbon fiber filter screen, which can intercept dust and debris in the air, prevent them from entering the exhaust component 324 and damaging the fan 3242, and is convenient for regular cleaning and replacement.

[0038] The mechanical pressing component 31 includes a rectangular groove 311, a drive roller 312, a pressure roller 313, a driver 314, and an elastic element 315. The rectangular groove 311 is opened in the frame 1, and the drive roller 312 is rotatably mounted inside it. The driver 314 for driving the roller 312 to rotate is embedded in the frame 1. The pressure roller 313 is mounted on one side of the frame 1 through the elastic element 315, so that the pressure roller 313 and the drive roller 312 are in close contact with each other.

[0039] Specifically, a rectangular groove 311 is formed inside the frame 1, and a drive roller 312 is rotatably mounted inside. The outer surface of the drive roller 312 is covered with a 5mm thick layer of natural rubber to increase the friction with the paper. A servo motor 314 is embedded in the frame 1 as a driver, and is connected to the drive roller 312 via a coupling, which can precisely control the speed of the drive roller 312. A pressure roller 313 is mounted on one side of the frame 1 via an elastic element 315. The outer surface of the pressure roller 313 is also covered with a layer of natural rubber, so that the pressure roller 313 and the drive roller 312 are in close contact and stably hold the paper.

[0040] The elastic element 315 includes a base 3151, a spring 3152 and a pusher block 3153. Pushers block 3153 are rotatably mounted on both ends of the pressure roller 313. Pushers block 3153 are slidably mounted in the base 3151, and spring 3152 is installed between the pusher block 3153 and the inner wall of the base 3151. One side of each of the two bases 3151 is fixed to the surface of the frame 1.

[0041] The pressure roller 313 has push blocks 3153 mounted on both ends of the roller via bearings. The push blocks 3153 are made of carbon steel and have been treated with anti-rust coating. The push blocks 3153 are slidably installed in the base 3151. The base 3151 adopts a U-shaped channel steel structure to ensure that the push blocks 3153 slide smoothly. A compression spring 3152 is installed between the push blocks 3153 and the inner wall of the base 3151, which can adaptively adjust the pressure of the pressure roller 313 according to the paper thickness. Both bases 3151 are fixed to the surface of the frame 1 by bolts on one side.

[0042] Two push blocks 3153 have rods 7 fixedly installed on one side, and one end of the two rods 7 passes through one side of the base 3151 and is fixedly installed with a pull rod 8.

[0043] Specifically, the rod 7 is a hollow stainless steel tube. One end of each rod 7 passes through a through hole on one side of the base 3151 and is fixedly installed with a circular pull rod 8. The surface of the pull rod 8 is provided with anti-slip texture. By pulling the pull rod 8, the position of the push block 3153 can be manually adjusted to facilitate the insertion of paper.

[0044] The cutter 2, motor and fan 3242 involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0045] The cutter in this application includes a driver, baffles, an output rod, and a cutting disc. Two baffles are fixed to one side of the frame 1, and an output rod with a cutting disc is rotatably mounted inside. One end of the output rod is equipped with a driver.

[0046] The top of the frame 1 of this device is equipped with a tube for placing the roll. The paper on the surface of the roll is pulled out, and the end passes through the drive roller 312 and the pressure roller 313. Under the action of the spring 3152, the push block 3153 drives the pressure roller 313 to come into contact with the surface of the drive roller 312, providing pressure for the paper. The motor can drive the drive roller 312 to rotate, realizing the paper conveying. The fan 3242 is started to discharge the air in the air frame 323 through the frame body 3241, so that the air frame 323 generates negative pressure. External air enters the air frame 323 through multiple air holes 322 in the plate body 321, so that the surface of the plate body 321 on the side of the paper generates negative pressure, reducing the gap between the paper and the conveying surface on one side of the frame 1. In the gap, under the rotation of the drive roller 312, the paper is cut by the cutter 2. A baffle 4 is provided in the air frame 323. The baffle 4 is located at the air inlet of the frame 3241. The air inlet of the frame 3241 is close to the center of the plate 321, which causes the airflow to be faster at the center of the plate 321 and slower at the edge. By setting the baffle 4 at the air inlet of the frame 3241, the airflow path at the center of the plate 321 can be extended, making the negative pressure suction on one side of the plate 321 more uniform. The drive roller 312 and the pressure roller 313 are both fixedly installed with rubber sleeves to increase friction. A filter plate 6 is provided in the frame 3241 to intercept dust and debris in the air and protect the fan 3242.
