Description

Technical Field

[0001] This utility model belongs to the field of paperboard crushing technology, and in particular relates to a raw material crushing device for paper pallet production. Background Technology

[0002] According to existing technology, a search revealed a Chinese patent that discloses "a crushing device for raw materials in paper pallet production", with the publication number "CN221218288U". This patent mainly uses the rotation of the crushing roller to crush the raw materials with the cutting tool, and then uses the rotation of the crushing wheel to further crush the raw materials. Through two crushing processes, both horizontal and vertical, the crushing effect is more significant, improving the practicality of the machine.

[0003] However, when crushing paper pallet raw materials, the aforementioned device cannot effectively shred the raw materials into flocculent form, which affects subsequent processing steps and prevents the achievement of the ideal material form. This not only prolongs the production cycle but also increases the complexity of the process, resulting in a decrease in overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a raw material crushing device for paper pallet production. By setting a crushing mechanism, it can pull wet paperboard particles into flocculent form, so that the flocculent raw material is discharged from the right side of the crushing cylinder under the push of the particles, thereby improving the raw material crushing effect and making the flocculent raw material easier to process in subsequent paper pallet production. This solves the problem that when crushing paper pallet raw materials, the above-mentioned device cannot effectively tear the raw material into flocculent form, which affects subsequent processing steps.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a raw material crushing device for paper pallet production, including a base plate, on which a crushing mechanism and a pulverizing mechanism are provided;

[0007] The crushing mechanism includes a conveying cylinder fixedly connected to the top surface of the base plate. A crushing box is connected to the top of the conveying cylinder. The crushing box is fixedly connected to the conveying cylinder. A motor is fixedly connected to the right side of the crushing box. A crushing roller one is fixedly connected to the output end of the motor through a coupling. A crushing roller two passes through the crushing box. The crushing roller two is rotatably connected to the crushing box. Gears are fixedly connected to the outer walls of both the crushing roller one and the crushing roller two. The two gears mesh with each other. Both gears are located on the left side of the crushing box. A feed inlet is opened on the top surface of the crushing box.

[0008] Furthermore, a rotating rod is rotatably connected to the inner wall of the conveying cylinder, and a pulley is fixedly connected to the outer wall of the rotating rod. Both the outer wall of the rotating rod and the outer wall of the crushing roller are fixedly connected to pulleys, and a belt is sleeved between the two pulleys.

[0009] Furthermore, a crushing mechanism is provided on the right side of the conveying cylinder, the crushing mechanism including a crushing cylinder connected to the right side of the conveying cylinder, the crushing cylinder being fixedly connected to the conveying cylinder.

[0010] Furthermore, the right end of the rotating rod extends rotatably to the right side of the crushing cylinder, a rotating roller is fixedly connected to the outer wall of the rotating rod, a support frame is fixedly connected to the top surface of the crushing cylinder, and the rotating rod rotates through the support frame.

[0011] Furthermore, a number of crushing teeth are fixedly connected to both the outer wall of the rotating roller and the inner wall of the crushing cylinder, with the crushing teeth on the inner wall of the rotating roller and the crushing teeth on the inner wall of the crushing cylinder interlacing with each other.

[0012] Furthermore, a constricted tube is connected to the top surface of the crushing cylinder, and the constricted tube is fixedly connected to the crushing cylinder. A sealing sleeve is connected to the top end of the constricted tube, and the sealing sleeve is fixedly connected to the constricted tube. A piston is slidably connected to the inner wall of the sealing sleeve, and a sliding rod is fixedly connected to the top surface of the piston. The sliding rod extends slidably to the top of the sealing sleeve, and a pressure block is fixedly connected to the top end of the sliding rod. A spring is wound around the outer wall of the sliding rod, one end of the spring is fixedly connected to the pressure block, and the other end of the spring is fixedly connected to the sealing sleeve.

[0013] Furthermore, a protrusion is fixedly connected to the outer wall of the second crushing roller, and the protrusion contacts the pressure block. A water storage box is fixedly connected to the right side of the crushing box. The top surface of the water storage box has a liquid inlet, and the bottom surface of the water storage box is connected to a liquid delivery pipe. The water storage box and the liquid delivery pipe are fixedly connected. One end of the liquid delivery pipe away from the water storage box extends into the interior of the sealing sleeve. The liquid delivery pipe and the sealing sleeve are fixedly connected. The connection point between the liquid delivery pipe and the sealing sleeve is located above the constricted tube and below the piston.

[0014] This utility model has the following beneficial effects:

[0015] 1. With the crushing mechanism installed, when the drive motor drives the first crushing roller to rotate, the second crushing roller rotates relative to the first crushing roller under the cooperation of two gears. This allows the second crushing roller and the first crushing roller to crush the paper pallet raw material fed into the feed inlet into large particles for subsequent processing. The crushed material falls into the inside of the conveying cylinder. At this time, under the action of two pulleys, the rotating rod and the first crushing roller rotate synchronously. The rotating rod drives the spiral blade to rotate, conveying the large particles of material that have fallen into the conveying cylinder from left to right.

[0016] 2. Equipped with a crushing mechanism, after water is added to the storage box through the inlet, the water flows into the sealed sleeve through the delivery pipe and slowly falls into the crushing cylinder under the action of the constriction tube. As the crushing roller slowly rotates to crush the raw material, it drives the protrusions to rotate. When the protrusions touch the pressure block, they press against the pressure block and slide rod, moving downwards. This allows the piston to squeeze the water below the piston, causing the water in the constriction tube to spray out quickly, increasing the water output speed. After the protrusions move away from the pressure block, the pressure block moves upwards under the reset action of the spring. The resetting mechanism can intermittently increase the water output speed. When the rotating rod drives the rotating roller, it will drive multiple crushing teeth to rotate. There is a gap between the outer wall of the rotating roller and the inner wall of the crushing cylinder to accommodate multiple crushing teeth. This allows the spiral blades to transport multiple large particles of material between the crushing cylinder and the rotating roller. The multiple staggered crushing teeth work together to pull the wet paperboard particles into flocculent material. The flocculent material is then discharged from the right side of the crushing cylinder under the push of the particles, improving the raw material crushing effect and making the flocculent material easier to process in subsequent paper tray production.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a raw material crushing device for paper pallet production, including a base plate 1, on which a crushing mechanism 2 and a pulverizing mechanism 3 are provided;

[0028] The crushing mechanism 2 includes a conveying cylinder 21 fixedly connected to the top surface of the base plate 1. A crushing box 22 is connected to the top of the conveying cylinder 21. The crushing box 22 is fixedly connected to the conveying cylinder 21. A motor 23 is fixedly connected to the right side of the crushing box 22. A crushing roller 24 is fixedly connected to the output end of the motor 23 via a coupling. A crushing roller 25 passes through the crushing box 22 and is rotatably connected to the crushing box 22. Gears 26 are fixedly connected to the outer walls of both the crushing roller 24 and the crushing roller 25. The two gears 26 mesh with each other and are located on the left side of the crushing box 22. A feed inlet 4 is opened on the top surface of the crushing box 22. A rotating rod 27 is rotatably connected to the inner wall of the conveying cylinder 21. A pulley 28 is fixedly connected to the outer wall of the rotating rod 27. Both the outer wall of 7 and the outer wall of crushing roller 24 are fixedly connected to pulleys 28. A belt 29 is sleeved between the two pulleys 28. With the crushing mechanism 2, when the drive motor 23 drives the crushing roller 24 to rotate, the crushing roller 25 rotates relative to the crushing roller 24 under the cooperation of the two gears 26. This allows the crushing roller 25 and the crushing roller 24 to crush the paper pallet raw material inside the feed inlet 4 into large particles for subsequent processing. The crushed material falls into the inside of the conveying cylinder 21. At this time, under the action of the two pulleys 28, the rotating rod 27 rotates synchronously with the crushing roller 24. The rotating rod 27 drives the spiral blade 31 to rotate, conveying the large particles inside the conveying cylinder 21 from left to right.

[0029] A crushing mechanism 3 is provided on the right side of the conveying cylinder 21. The crushing mechanism 3 includes a crushing cylinder 32 connected to the right side of the conveying cylinder 21. The crushing cylinder 32 is fixedly connected to the conveying cylinder 21. The right end of the rotating rod 27 extends rotatably to the right side of the crushing cylinder 32. A rotating roller 33 is fixedly connected to the outer wall of the rotating rod 27. A support frame 35 is fixedly connected to the top surface of the crushing cylinder 32. The rotating rod 27 rotates through the support frame 35. Several crushing teeth 34 are fixedly connected to both the outer wall of the rotating roller 33 and the inner wall of the crushing cylinder 32. The crushing teeth 34 on the inner wall of the rotating roller 33 and the crushing teeth 34 on the inner wall of the crushing cylinder 32 are interleaved. A constricting tube 36 is provided on the top surface of the crushing cylinder 32. The constricting tube 36 is fixedly connected to the crushing cylinder 32. A sealing sleeve 37 is provided at the end of the crushing roller 25. The sealing sleeve 37 is fixedly connected to the constricted tube 36. A piston 38 is slidably connected to the inner wall of the sealing sleeve 37. A sliding rod 39 is fixedly connected to the top surface of the piston 38. The sliding rod 39 extends slidably to the top of the sealing sleeve 37. A pressure block 391 is fixedly connected to the top of the sliding rod 39. A spring 396 is wound around the outer wall of the sliding rod 39. One end of the spring 396 is fixedly connected to the pressure block 391, and the other end of the spring 396 is fixedly connected to the sealing sleeve 37. A protrusion 392 is fixedly connected to the outer wall of the crushing roller 25. The protrusion 392 contacts the pressure block 391. A water storage box 393 is fixedly connected to the right side of the crushing box 22. An inlet 394 is opened on the top surface of the water storage box 393. An infusion port is provided on the bottom surface of the water storage box 393. Pipe 395, water storage box 393 and infusion pipe 395 are fixedly connected. The end of infusion pipe 395 away from water storage box 393 extends into the interior of sealing sleeve 37. Infusion pipe 395 and sealing sleeve 37 are fixedly connected. The connection between infusion pipe 395 and sealing sleeve 37 is located above constricted tube 36 and below piston 38. With the crushing mechanism 3, after water is injected into water storage box 393 through inlet 394, water flows into the interior of sealing sleeve 37 through infusion pipe 395 and slowly falls into crushing cylinder 32 under the action of constricted tube 36. When crushing roller 25 slowly rotates to crush raw materials, it will drive protrusion 392 to rotate, so that protrusion 392 touches the pressure block 3. At position 91, the pressure block 391 and slide rod 39 move downwards, allowing piston 38 to squeeze the water in the lower part of piston 38, causing the water in constricted tube 36 to spray out quickly, increasing the water output speed. After the protrusion 392 moves away from the pressure block 391, the pressure block 391 moves upwards to reset under the reset action of spring 396, intermittently increasing the water output speed. When the rotating rod 27 drives the rotating roller 33 to rotate, it drives multiple crushing teeth 34 to rotate. A gap is provided between the outer wall of the rotating roller 33 and the inner wall of the crushing cylinder 32 to accommodate multiple crushing teeth 34, so that the spiral blades 31 can transport multiple large particles of material between the crushing cylinder 32 and the rotating roller 33. The multiple staggered crushing teeth 34 cooperate with each other to pull the wet paperboard particles into flocculent form.This allows the flocculent raw material to be discharged from the right side of the crushing cylinder 32 under the push of the granular material, improving the raw material crushing effect and making the flocculent raw material easier to process into paper pallets later.

[0030] One specific application of this embodiment is as follows: The main component of paper is cellulose fiber. When a small amount of water is added, water molecules will enter the amorphous region of the cellulose fiber, causing the fiber to swell. The swollen fiber becomes softer and more elastic, and the binding force between the fibers is relatively weakened. It is easier to separate them during the crushing process, which is conducive to the formation of flocculent structure and facilitates subsequent processing.

[0031] With the crushing mechanism 2 in place, when the drive motor 23 drives the first crushing roller 24 to rotate, the two gears 26 work together to make the second crushing roller 25 rotate relative to the first crushing roller 24. This allows the second crushing roller 25 and the first crushing roller 24 to crush the paper tray raw material inside the feed inlet 4 into large particles for easier subsequent processing. The crushed material falls into the conveying cylinder 21. At this time, under the action of the two pulleys 28, the rotating rod 27 rotates synchronously with the first crushing roller 24. The rotating rod 27 drives the spiral blade 31 to rotate, conveying the large particles inside the conveying cylinder 21 from left to right.

[0032] With the crushing mechanism 3 in place, after water is poured into the water storage box 393 through the inlet 394, the water flows into the sealed sleeve 37 through the delivery pipe 395 and slowly falls into the crushing cylinder 32 under the action of the constriction tube 36. When the crushing roller 25 slowly rotates to crush the raw material, it drives the protrusion 392 to rotate. When the protrusion 392 touches the pressure block 391, it will push against the pressure block 391 and the slide rod 39 and move downward, so that the piston 38 can squeeze the water in the lower part of the piston 38, so that the water in the constriction tube 36 can be sprayed out quickly, increasing the water output speed. After the protrusion 392 moves away from the pressure block 391, the spring 396 returns to its original position. The pressure block 391 moves upward and resets, intermittently increasing the water output speed. When the rotating rod 27 drives the rotating roller 33 to rotate, it drives multiple crushing teeth 34 to rotate. A gap is provided between the outer wall of the rotating roller 33 and the inner wall of the crushing cylinder 32 to accommodate multiple crushing teeth 34. This allows the spiral blades 31 to transport multiple large particles to the space between the crushing cylinder 32 and the rotating roller 33. The multiple staggered crushing teeth 34 work together to pull the wet paperboard particles into flocculent material. The flocculent material is then discharged from the right side of the crushing cylinder 32 under the push of the particles, improving the raw material crushing effect and making the flocculent material easier for subsequent paper tray processing.
