Description

Technical Field

[0001] The invention relates to the technical field of paper product manufacturing, and in particular to a waste collection device for paper product manufacturing. Background Art

[0002] During the paper product manufacturing process, the formed paper needs to be cut, printed, and bound according to the purpose of the paper product to make various finished products such as books, cartons, and paper towels. When making books and cartons, in order to optimize the printing quality of the product edges and make the product specifications uniform, the edges of the paper need to be cut. Since paper product waste is essentially still a fiber resource with a high recycling value, collecting and processing the cut waste can reduce dependence on virgin fiber resources, reduce production costs, and achieve resource recycling.

[0003] Traditional paper waste collection devices can collect the waste generated by cutting cardboard in a unified manner so that the waste can be reused. In the collection process, in order to make the waste uniform in size and facilitate the reprocessing of the waste, it is necessary to use a motor to drive the crushing roller to crush the waste. At the same time, in order to continuously and efficiently collect, the crushing rollers are usually arranged horizontally, and the blades on adjacent crushing rollers are staggered. After the wider paper waste enters between the crushing rollers, it will be quickly cut and crushed by the blades. However, the waste generated when trimming the cardboard is in the shape of strips, and the width is generally less than three centimeters, or even only a few millimeters, and the shape of this kind of paper waste is The irregularity makes it difficult to maintain a horizontal posture when sliding between the crushing rollers. Therefore, the following two situations may occur during the crushing process. First, when the cardboard strips vertically enter between the crushing rollers, they are easily misaligned with the cutting position of the blades, and the blades are difficult to effectively grab the cardboard strips; second, the cardboard strips fall vertically and rest on the crushing rollers. At this time, the crushing rollers and the cardboard strips will slip. Both of the above situations will result in the cardboard strips not being brought into the crushing area in time when they are collected, resulting in low waste collection efficiency, and even causing the cardboard strips to be entangled on the crushing rollers, hindering subsequent waste collection. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the strip paper waste is narrow in width and irregular in shape, and it is difficult to maintain a horizontal posture when sliding between the crushing rollers. When entering between the crushing rollers, it is easy to be misaligned with the cutting position of the blade or slip on the crushing roller, making it difficult for the blade to effectively grab the strip paperboard and unable to bring the strip paperboard into the crushing area in time, resulting in low waste collection efficiency. A waste collection device for paper product manufacturing is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a waste collection device for paper product manufacturing: comprising a collection box, a crushing mechanism is installed on the top of the collection box, and a feed port is provided on the top of the crushing mechanism, and further comprising: The posture adjustment mechanism includes a servo motor fixedly mounted on the outer shell of the pulverizing mechanism, a plurality of drive units are arranged inside the feed port, a transmission assembly is arranged between the servo motor and the drive unit, the inside of the feed port is fixedly connected to the support frame, and each of the drive units is provided with two push plates; An auxiliary mechanism, the auxiliary mechanism comprising a rotating shaft rotatably connected to the inside of the feed port, a gear fixedly connected to the rotating shaft, and a pressing unit disposed outside the rotating shaft; Driven by the servo motor, the transmission assembly and the driving unit, the adjacent push plates push the two ends of the strip paperboard in opposite directions, so that the strip paperboard falls in a horizontal posture.

[0006] As a further description of the above technology, a waste collection device for paper product manufacturing is as follows: the driving unit includes two toothed discs rotatably connected to the inside of the feed port, and the external transmission of the two toothed discs is connected with a transmission belt.

[0007] As a further description of the above technology, a waste collection device for paper product manufacturing is described as follows: the transmission assembly includes a pulley 1 and a pulley 2 which are fixed to the servo motor drive shaft and the gear disk respectively, and a synchronous belt is connected between the pulley 1 and the pulley 2.

[0008] As a further description of the above technology, a waste collection device for paper product manufacturing is provided: the pressing unit comprises a paper pressing plate, and a cutter is fixedly connected to the inner wall of the feed port.

[0009] As a further description of the above technology, a waste collection device for paper product manufacturing is provided: a folding groove is provided at the blade of the cutter, and when the paper pressing plate presses the strip of paperboard into the folding groove of the cutter, the strip of paperboard is aligned and folded.

[0010] As a further description of the above-mentioned technology, a waste collection device for paper product manufacturing is provided: a filter assembly is arranged on the feed port, and the filter assembly includes a cover body fixed to the inner wall of the feed port, and filter boxes are detachably connected to both sides of the feed port, and air pipes are fixedly connected between the cover body and the filter box and between adjacent cover bodies, and blades are fixedly connected between the paper pressing plate and the rotating shaft.

[0011] As a further description of the above-mentioned technology, a waste collection device for paper product manufacturing is provided: the inner wall of the pulverizing chamber of the pulverizing mechanism is fixedly connected with a hollow baffle plate which is connected with the cover body through an air pipe.

[0012] As a further description of the above-mentioned technology, a waste collection device for paper product manufacturing is provided: the gear is meshed and connected with the transmission belt, and the transmission belt drives the gear to rotate when it moves in a circular motion.

[0013] As a further description of the above-mentioned technology, a waste collection device for paper product manufacturing is provided: the inner wall of the feed port is fixedly connected with a guide plate located above the toothed disc.

[0014] As a further description of the above-mentioned technology, a waste collection device for paper product manufacturing also includes: a separation mechanism, which includes a mounting seat fixed between a push plate and a transmission belt, a roller rotatably connected inside the mounting seat, a worm fixedly connected to the top of the roller, and a worm gear and a paddle roller rotatably connected to one side of the push plate, and the worm gear and the worm gear are meshed with each other.

[0015] In summary, due to the use of the above-mentioned technology, the waste collection device for paper product manufacturing has the following beneficial effects: When collecting cardboard cutting waste, the present application allows the strip cardboard falling horizontally to pass through the gap between the support frames and be quickly shredded by the pulverizing rollers inside the pulverizing mechanism. The cardboard falling vertically is supported by the support frames, and the longitudinal cardboard is pushed by the staggered push plates, so that the longitudinal cardboard can be deflected horizontally until the cardboard falls from between the support frames. This design can adjust the falling posture of the strip cardboard when collecting cardboard cutting waste, so that the strip cardboard falls horizontally, making full use of the pulverizing rollers arranged horizontally in the pulverizing mechanism, accelerating the pulverizing and collecting efficiency, and helping to make the pulverized cardboard more uniform, which is convenient for reprocessing after collection. At the same time, it can also reduce the local wear of the pulverizing rollers and extend the service life of the pulverizing mechanism. The paperboard that cannot be adjusted in angle can be pressed down by the paper pressing plate, so as to achieve the effect of auxiliary feeding and prevent the paperboard from being blocked between the push plate and the end of the support frame. Moreover, the paper pressing plate presses down the paperboard, so that the paperboard will bend and pass through between the support frames. After the paperboard is pressed into the folding groove of the cutter, the bent strip of paperboard is folded in half under the pressure of the folding groove, and then the cutter cuts the paperboard. In this process, the strip of paperboard is cut and the transition from longitudinal to transverse is achieved, so as to accelerate the efficiency of the paperboard being crushed by the crushing mechanism, thereby improving the collection efficiency of waste materials. The vertically falling strip cardboard will be crushed slowly, or even misaligned with the cutting position of the blade and cannot be crushed. The push plate can also push the vertical cardboard while moving, causing the vertical cardboard to tilt or even fall sideways, thereby improving the crushing and collection efficiency of the device for the vertically falling cardboard; When the cut strip waste cardboard is crushed and collected, the blades rotate to suck the generated dust into the filter box, thereby filtering and collecting the dust and avoiding dust. Moreover, the output airflow can be ejected through the holes on the hollow baffle plate to push the cardboard close to the inner wall of the crushing chamber of the crushing mechanism into the crushing chamber, thereby avoiding the situation where the cardboard is attached to the inner wall of the crushing chamber of the crushing mechanism and cannot be grasped by the crushing roller, thereby avoiding the presence of waste residue in the crushing mechanism and improving the collection rate of waste. Cardboard will be pressed when being cut, so it is easy for adjacent cardboards to stick together. The separation mechanism can break the adhesion between cardboards when the push plate pushes the cardboard, so that the cardboard is spread out and easier to be crushed, which helps save energy and reduce the probability of servo motor failure due to long-term high-load operation.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a waste collection device for paper product manufacturing. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 8 As shown, the present invention provides a waste collection device for paper product manufacturing: comprising a collection box 10, a crushing mechanism 12 is installed on the top of the collection box 10, the crushing mechanism 12 is composed of a shell, a motor and a plurality of crushing rollers, the crushing rollers are located in a crushing cavity inside the shell, a feed port 11 is provided on the top of the crushing mechanism 12, and further comprising: The posture adjustment mechanism 20 includes a servo motor 21 fixedly mounted on the outer shell of the crushing mechanism 12, a plurality of drive units 23 are arranged inside the feed port 11, a transmission assembly 22 is arranged between the servo motor 21 and the drive unit 23, a plurality of support frames 24 arranged in parallel and at equal distances are fixedly connected inside the feed port 11, and each drive unit 23 is provided with two push plates 25 facing in opposite directions; The auxiliary mechanism 30 includes a rotating shaft 32 rotatably connected to the inside of the feed port 11, a gear 31 is fixedly connected to the rotating shaft 32, and a pressing unit 33 is arranged outside the rotating shaft 32; Driven by the servo motor 21, the transmission assembly 22 and the driving unit 23, the adjacent push plates 25 push the two ends of the strip paperboard in opposite directions, so that the strip paperboard falls in a horizontal posture.

[0020] Reference Figure 3 and Figure 4The driving unit 23 includes two toothed discs 231 rotatably connected to the inside of the feed port 11. The inner wall of the feed port 11 is fixedly connected with a guide plate 26 located above the toothed discs 231, which is used to guide the falling strip paperboard to prevent the paperboard from contacting the toothed discs 231. The external transmission of the two toothed discs 231 is connected with a transmission belt 232. The rotation of one of the toothed discs 231 can drive the transmission belt 232 to circulate outside the two toothed discs 231. The inner wall of the transmission belt 232 is provided with convex teeth. When the toothed discs 231 and the transmission belt 232 are transmitted, it can be ensured that there is no slippage between the two, so as to avoid the misalignment of the push plates 25 on the adjacent driving units 23. Each support frame 24 is supported below the position where the transmission belt 232 is not in contact with the toothed disc 231, so as to improve the bearing capacity of the transmission belt 232, avoid the bending of the transmission belt 232 caused by the gravity of the paperboard, and The vertically falling strip cardboard is supported to prevent the longitudinal cardboard from falling directly into the crushing chamber of the crushing mechanism 12, waiting for the subsequent angle adjustment of the longitudinal cardboard by the push plate 25. At the same time, each push plate 25 is located at the center position of the support frame 24 below it, so that adjacent push plates 25 can move in the opposite direction synchronously by the same distance, giving full play to the effect of pushing and adjusting the angle of the strip cardboard. The gear 31 is meshed and connected with the transmission belt 232. The transmission belt 232 drives the gear 31 to rotate when it moves in a cycle. There is no need to set up an additional driving structure, which simplifies the equipment structure, and enables the posture adjustment mechanism 20 and the auxiliary mechanism 30 to be used synchronously, reducing the operating complexity of the device. The gears 31 located on both sides of the feed port 11 are respectively meshed with the two sides of the transmission belt 232, so that the transmission belt 232 drives the gears 31 on both sides of the feed port 11 to rotate in the opposite direction when it moves in a cycle.

[0021] The transmission assembly 22 includes a pulley 1 221 and a pulley 2 222 respectively fixed to the driving shaft of the servo motor 21 and the toothed disc 231. The toothed disc 231 close to the servo motor 21 in each driving unit 23 is fixed to the pulley 2 222. The number of pulleys 1 221 fixed on the driving shaft of the servo motor 21 is the same as the number of pulleys 2 222. A synchronous belt 223 is connected between each pulley 1 221 and each pulley 2 222. When the servo motor 21 is started to drive all the pulleys 1 221 to rotate, each pulley 2 222 is driven by the synchronous belt 223 to rotate, so that the toothed disc 231 in each driving unit 23 rotates synchronously.

[0022] Reference Figure 6In order to prevent the strip of cardboard from being blocked on one side of the push plate 25, the pressing unit 33 includes a paper pressing plate 331. The inner wall of the feed port 11 is fixedly connected with a cutter 332. When the transmission belt 232 moves to drive the push plate 25 to push the cardboard that cannot be adjusted in angle to one end of the support frame 24, the transmission belt 232 simultaneously drives the gear 31 and the rotating shaft 32 to rotate, driving the paper pressing plate 331 to rotate and press the strip of cardboard downward. At this time, the strip of cardboard is bent under the pressure of the paper pressing plate 331, so that the cardboard is no longer placed on the support frame 24. Then the paper pressing plate 331 rotates to drive the cardboard close to the cutter 332. In this process, the cardboard will not be moved under the action of friction. When the paper strip falls off the paper pressing plate 331 and the paper pressing plate 331 and the cutter 332 are interlaced, the cardboard is cut. A folding groove is provided at the blade of the cutter 332. When the paper pressing plate 331 presses the strip cardboard into the folding groove of the cutter 332, the strip cardboard is aligned and folded, so that the cardboard is more parallel to the support frame 24 and the pulverizing roller inside the pulverizing mechanism 12. During the above process, the strip cardboard is switched from a state of being erected on the support frame 24 and perpendicular to the support frame 24 to a state of falling into the pulverizing chamber and being parallel to the support frame 24. Since the support frame 24 is parallel to the pulverizing roller, the efficiency of the pulverizing roller in shredding the strip cardboard can be accelerated after the state of the strip cardboard is switched.

[0023] Reference Figure 2-Figure 5 A filter assembly 34 is provided on the feed port 11. The filter assembly 34 includes a cover body 341 fixed to the inner wall of the feed port 11. A blade 343 located inside the cover body 341 is fixedly connected between the paper pressing plate 331 and the rotating shaft 32. A plurality of blades 343 are arranged in a central array around the rotating shaft 32. Filter boxes 344 are detachably connected to both sides of the feed port 11. Air pipes 342 are fixedly connected between the cover body 341 and the filter boxes 344 and between adjacent cover bodies 341. When the rotating shaft 32 drives the blades 343 to rotate, negative pressure is generated inside the cover body 341, and external air enters the cover body 341 through the filter box 344. 41, the air inlet of the filter box 344 is located in the feed port 11. When the air passes through the inside of the filter box 344, the dust generated when the waste is crushed and collected is filtered by the filter box 344. The inner wall of the crushing chamber of the crushing mechanism 12 is fixedly connected with a hollow baffle 35 which is connected to the cover body 341 through an air pipe 342. The blade 343 rotates to input the air into the hollow baffle 35 through the air pipe 342, so that the air is ejected through the air outlet of the hollow baffle 35, and the cardboard close to the inner wall of the crushing chamber of the crushing mechanism 12 is pushed into the crushing chamber to avoid the situation that the cardboard sticks to the inner wall of the crushing chamber of the crushing mechanism 12 and cannot be grasped by the crushing roller.

[0024] Reference Figure 7 and Figure 8In order to prevent the strips of cardboard from sticking together and being difficult to crush and collect, a separation mechanism 40 is also included. The separation mechanism 40 includes a mounting seat 41 fixed between the push plate 25 and the transmission belt 232. The mounting seat 41 is internally rotatably connected with a roller 42 that fits the inner wall of the support frame 24. During the process of the transmission belt 232 cyclically rotating to drive the mounting seat 41 to move, the roller 42 rolls on the inner wall of the support frame 24. A worm 43 is fixedly connected to the top of the roller 42. A worm gear 44 and a toggle roller 45 that are fixed to each other are rotatably connected to one side of the push plate 25. The worm 43 and the worm gear 44 are meshed with each other. When the roller 42 rolls, the worm 43 is driven to rotate. The toggle roller 45 is driven by the worm gear 44 to rotate and toggle the strip of cardboard pushed by the push plate 25 upward, so that the cardboard is dispersed and spread out to be easier to crush.

[0025] Working principle: In the initial state, each push plate 25 is located below the guide plate 26, the pulverizing mechanism 12 is started, and then the strip waste generated after the cardboard is cut is put into the feed port 11, and the cardboard falling horizontally passes through the gap between the support frames 24 and falls into the pulverizing chamber of the pulverizing mechanism 12, and is collected by the collection box 10 after being pulverized. The cardboard falling vertically is supported by the support frame 24, and the cardboard falling vertically is inserted into the pulverizing roller. When the pulverizing roller rotates, the horizontal cardboard is quickly pulverized, and the vertical cardboard is pulverized slowly, and even the cardboard and the blade of the pulverizing roller are offset and cannot be pulverized; The servo motor 21 is started to drive the pulley 1 221 to rotate, and the pulley 2 222 is driven to rotate through the synchronous belt 223, so that a toothed disc 231 in each driving unit 23 rotates, and the transmission belt 232 is driven to circulate and rotate outside the two toothed discs 231, and the mounting seat 41 and the push plate 25 move following the transmission belt 232, and the adjacent push plates 25 move toward each other, pushing the strip paperboard mounted on the support frame 24, so that the paperboard changes from the longitudinal direction to the transverse direction, so that the paperboard falls from the gap between the support frames 24 to be crushed and collected; When there is a cardboard that cannot be adjusted to fall, the push plate 25 moves to push the cardboard to one end of the support frame 24. At this time, the transmission belt 232 circulates to drive the gear 31 and the rotating shaft 32 to rotate, and then drives the blade 343 and the pressure plate 331 to rotate. The pressure plate 331 rotates to press the strip of cardboard downward. At this time, the strip of cardboard is bent under the pressure of the pressure plate 331, causing the cardboard to pass through the gap between the support frames 24. Then the pressure plate 331 rotates to drive the cardboard close to the cutter 332. In this process, the cardboard will not fall off the pressure plate 331 due to the friction force. When the cardboard enters the folding groove of the cutter 332, under the pressure of the inner wall of the folding groove, the cardboard is folded in half and tends to be parallel to the crushing roller. Then the pressure plate 331 and the cutter 332 alternately cut the cardboard, so that the cardboard falls and is crushed and collected. During the rotation of the blades 343, the air around the feed port 11 is sucked into the cover body 341 through the filter box 344 and the air pipe 342, and the air is ejected from the air outlet holes on the hollow baffle 35 through the air pipe 342. The ejected air pushes the cardboard close to the inner wall of the pulverizing chamber of the pulverizing mechanism 12 into the pulverizing chamber, thereby preventing the cardboard from being attached to the inner wall of the pulverizing chamber of the pulverizing mechanism 12 and being unable to be caught by the pulverizing roller. When the push plate 25 pushes the cardboard, the mounting seat 41 moves inside the support frame 24, causing the roller 42 to roll on the inner wall of the support frame 24, driving the worm 43 to rotate, and the worm gear 44 drives the shifting roller 45 to rotate upward to shift the strip of cardboard pushed by the push plate 25, so that the cardboard is dispersed and spread out, making it easier to be broken under the shearing of the crushing roller.
