Description

Technical Field

[0001] The invention relates to the field of pulverizers, in particular to a pulverizer. Background Art

[0002] A pulverizer is a mechanical device used to break larger objects into small pieces or powder. Among pulverizers, there is a plastic pulverizer, which is a device specifically used to process waste plastics. It can break plastic packaging into smaller pieces for further recycling or processing. This equipment is of great significance in reducing environmental pollution and saving resources.

[0003] The plastic crusher that actually crushes the plastic packaging tape usually takes out the plastic packaging tape raw materials placed in bags manually and places them on a horizontal conveyor belt. The moving knife inside the crusher cooperates with the fixed knife to crush the plastic packaging tape raw materials, and the crushed plastic packaging tape raw materials are discharged by an oblique conveyor belt.

[0004] Although the above-mentioned plastic crusher can effectively crush the plastic packaging tape raw materials, since the plastic packaging tape raw materials are loaded manually, the placement position of the plastic packaging tape raw materials cannot be determined, so that the plastic packaging tape raw materials may be stuck between the horizontal conveyor belt and the plastic crusher shell, and since the plastic packaging tape raw materials are in a fluffy state, they are very easy to fall from the upper side of the plastic crusher shell, and need to be picked up and placed again manually, thereby reducing the crushing efficiency of the plastic packaging tape raw materials; in addition, since the movable knife cooperates with the fixed knife to crush the plastic packaging tape raw materials, the plastic packaging tape raw materials will be entangled on the movable knife due to their own long strip shape, which will not only reduce the crushing efficiency of the movable knife and the fixed knife, but also the movable knife cannot rotate smoothly after the plastic packaging tape raw materials are entangled too much, thereby affecting the normal operation of the crusher.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0029] See also Figure 1 and Figure 8 A crusher comprises a U-shaped shell 1, a closing plate 11 is fixed on both sides of the left and right sides of the U-shaped shell 1, a horizontal conveyor belt 12 and an oblique conveyor belt 13 are respectively arranged between the two vertical sections of the U-shaped shell 1 and on the left and right sides, and a material blocking plate 131 is evenly arranged on the oblique conveyor belt 13, a crushing part 2 is arranged between the two vertical sections of the U-shaped shell 1 and between the horizontal conveyor belt 12 and the oblique conveyor belt 13, and a raw material concentrating part 3 and a pressing part 4 are arranged in sequence from left to right at the top of the two vertical sections of the U-shaped shell 1 and above the horizontal conveyor belt 12.

[0030] The present invention sequentially feeds and discharges materials through a horizontal conveyor belt 12 and an oblique conveyor belt 13, and at the same time, the plastic packaging tape raw material is thoroughly crushed through the crushing section 2, and the raw material concentrating section 3 and the pressing section 4 can compress and tighten the plastic packaging tape raw material during the process of being conveyed by the horizontal conveyor belt 12, and at the same time, the raw material concentrating section 3 can also push the plastic packaging tape raw material to the middle position of the horizontal conveyor belt 12, thereby preventing the plastic packaging tape raw material from falling from the top of the U-shaped shell 1 or getting stuck in the gap between the horizontal conveyor belt 12 and the U-shaped shell 1, thereby ensuring the utilization rate of the plastic packaging tape raw material.

[0031] Specifically, the operator first takes out the plastic packaging tape raw materials placed in bags and places them on the horizontal conveyor belt 12, and then controls the horizontal conveyor belt 12 to transfer the plastic packaging tape raw materials from left to right. Since the plastic packaging tape raw materials just taken out are in a fluffy state, the plastic packaging tape raw materials may fall from the U-shaped shell 1, and in the conveying process, the operator loads the materials, which causes the position of the plastic packaging tape raw materials to be biased towards the edge of the horizontal conveyor belt 12, and then causes the plastic packaging tape raw materials to be stuck in the gap between the horizontal conveyor belt 12 and the U-shaped shell 1, thereby reducing the utilization rate of the raw materials. The raw material concentrating part 3 is driven by the pressing part 4 to push the plastic packaging tape raw materials to the middle position of the horizontal conveyor belt 12, and the pressing part 4 and the raw material concentrating part 3 can both press down the plastic packaging tape raw materials, so that the plastic packaging tape raw materials can be smoothly conveyed to the right end position by the horizontal conveyor belt 12.

[0032] When the plastic packaging tape raw material is transported to the crushing section 2 by the horizontal conveyor belt 12, the crushing section 2 will fully crush the plastic packaging tape raw material. After the plastic packaging tape raw material is crushed, it will fall onto the inclined conveyor belt 13 and be transported to the upper right by the inclined conveyor belt 13 to complete the discharge.

[0033] See also Figure 2 and Figure 3 The pressing part 4 includes a vertical plate 41 fixed on the top of the two vertical sections of the U-shaped shell 1 respectively, and a second motor 411 is installed on the front side of the vertical plate 41 on the front side through a motor sleeve, and a power shaft 412 is installed on the two vertical plates 41 for rotation together, and a plurality of groups of circumferentially arranged pressing pointed rods 413 are linearly and evenly arranged on the side of the power shaft 412, and the output end of the second motor 411 is connected to the front end of the power shaft 412, and a transmission component 42 is arranged at the rear end of the power shaft 412; the transmission component 42 includes a power rod 421 fixed on the side of the rear end of the power shaft 412, and a connecting rod 422 is rotatably installed on the power rod 421; a vertical rod 423 is fixed on the top of the vertical plate 41 on the rear side, and a vertical sliding sleeve 424 is sleeved on the outer side of the vertical rod 423, and a driven shaft 425 is fixed on the rear side of the vertical sliding sleeve 424, and the rear end of the driven shaft 425 is rotatably installed on the end of the connecting rod 422 away from the power rod 421.

[0034] The pressing portion 4 mainly presses the plastic packaging belt raw material by means of the continuously rotating pressing pointed rod 413, so that the fluffy plastic packaging belt raw material is pressed and close to the horizontal conveyor belt 12, thereby preventing the plastic packaging belt raw material from falling from the horizontal conveyor belt 12 to the outside of the U-shaped shell 1, and the transmission component 42 can drive the raw material concentrating portion 3 to concentrate and further press the plastic packaging belt raw material, thereby avoiding the situation where the plastic packaging belt raw material cannot be completely close to the horizontal conveyor belt 12 due to a single pressing.

[0035] Specifically, the operator first takes out the plastic packaging tape raw materials placed in bags and places them on the horizontal conveyor belt 12, and then controls the horizontal conveyor belt 12 to transfer the plastic packaging tape raw materials from left to right. In the process of the plastic packaging tape raw materials moving from left to right, the second motor 411 is controlled to drive the power shaft 412 to rotate counterclockwise. Due to the rotation of the power shaft 412, the pressing pointed rod 413 will press and pierce the plastic packaging tape raw materials downward, thereby ensuring that the plastic packaging tape raw materials are close to the horizontal conveyor belt 12.

[0036] And the power shaft 412 will drive the power rod 421 to rotate, and the rotating power rod 421, connecting rod 422 and vertical sleeve 424 will form a crank slider structure, so that the vertical sleeve 424 will reciprocate up and down, and then the vertical sleeve 424 will synchronously drive the raw material concentration part 3 to reciprocate up and down. In the process of the raw material concentration part 3 moving downward, it will press the plastic packaging belt raw material downward and concentrate the pressed plastic packaging belt raw material to the middle position of the horizontal conveyor belt 12.

[0037] Continue reading Figure 2 and Figure 3 A fixing rod 414 is fixed to the front side of the front vertical section of the U-shaped housing 1 and is located on the right side of the power shaft 412. A positioning plate 415 is fixed to the rear side of the top of the fixing rod 414. A plurality of positioning pins 416 are provided through the middle of the positioning plate 415. A tension spring is connected between the end of each positioning pin 416 away from the power shaft 412 and the positioning plate 415. A sloped abutment rod 417 is fixed to the end of all positioning pins 416 close to the power shaft 412. The sloped abutment rod 417 is used to prevent the plastic packaging tape material from being twisted around the pressing point rod 413, thereby ensuring the pressing efficiency of the pressing point rod 413. Through the elastic action of the tension spring, the sloped abutment rod 417 removes the plastic packaging tape material on the pressing point rod 413 without hindering the continuous rotation of the pressing point rod 413.

[0038] See also Figure 2-Figure 4The raw material concentration part 3 includes a sliding column 31 fixed on the top of the two vertical sections of the U-shaped shell 1, and a synchronous sleeve 311 is sleeved on the side of each sliding column 31. A horizontal rod 312 is fixed between the synchronous sleeve 311 on the rear side and the vertical sleeve 424. A vertical moving plate 313 is fixed between the two synchronous sleeves 311. A vertical moving block 314 is fixed at the bottom of the vertical moving plate 313. A lower pressing plate 315 is fixed at the bottom of the vertical moving block 314. Concentrating components 32 are symmetrically arranged on the front and rear sides of the vertical moving block 314.

[0039] See also Figure 2-Figure 5 The central component 32 includes a longitudinal limit rod 321 symmetrically fixed on the top of the two vertical sections of the U-shaped shell 1, and the opposite ends of the two longitudinal limit rods 321 are slidably connected with a longitudinal sliding sleeve 322. A mounting rod 323 is fixed on the top of each longitudinal sliding sleeve 322. A circular sleeve 324 is slidably connected to the side of the mounting rod 323. A vertical spring is connected between the circular sleeve 324 and the longitudinal sliding sleeve 322. A downward pressing frame 325 is fixed on the left side of the circular sleeve 324, and an oblique limit rod 326 is fixed in the downward pressing frame 325. An oblique sliding sleeve 327 sleeved on the oblique limit rod 326 is symmetrically fixed on the front and rear sides of the vertical moving block 314, and an oblique spring is connected between the oblique sliding sleeve 327 and the bottom of the downward pressing frame 325.

[0040] The raw material concentration part 3 can be driven by the transmission component 42 and concentrate the raw materials to the middle position of the horizontal conveyor belt 12. The inclined sliding sleeve 327 cooperates with the inclined limiting rod 326 to enable the downward pressing frame 325 to drive the plastic packaging belt raw materials to move to the middle position of the horizontal conveyor belt 12, thereby avoiding the situation where the plastic packaging belt raw materials are stuck in the gap between the horizontal conveyor belt 12 and the U-shaped shell 1, thereby ensuring the utilization rate of the plastic packaging belt raw materials and ensuring the normal transportation of the horizontal conveyor belt 12. At the same time, the downward pressing frame 325 can press down the plastic packaging belt raw materials in advance, thereby cooperating with the downward pressing part 4 to ensure the downward pressing effect on the plastic packaging belt raw materials.

[0041] Specifically, as the vertical sleeve 424 reciprocates up and down, the synchronous sleeve 311 will reciprocate up and down together with the vertical sleeve 424 due to the driving action of the horizontal rod 312. When the synchronous sleeve 311 moves downward, the vertical movable plate 313 will drive the vertical movable block 314 and the lower pressure plate 315 to move downward together, so that the lower pressure plate 315 presses the plastic packaging belt raw material in the middle position of the horizontal conveyor belt 12 and makes the plastic packaging belt raw material close to the horizontal conveyor belt 12.

[0042] The inclined sleeve 327 will compress the oblique spring and, under the action of the oblique limit rod 326, make the two pressing frames 325 move toward each other, thereby making the plastic packaging tape raw materials at the edge of the horizontal conveyor belt 12 move to the middle position of the horizontal conveyor belt 12.

[0043] In this embodiment, if Figure 4 As shown, in order to ensure that the oblique sliding sleeve 327 first drives the lower pressing frame 325 to move downward, the elastic coefficient of the oblique spring should be higher than the elastic coefficient of the vertical spring, so that the vertical spring is deformed first.

[0044] See also Figure 1 , Figure 2 and Figure 6 A closing component 43 driven by a transmission component 42 is arranged on the left side of the crushing part 2; the closing component 43 includes a rotating plate 431 hinged on the left side of the crushing part 2, and a plurality of pressing rods 432 are evenly arranged longitudinally on the bottom of the rotating plate 431; a transmission rod 433 is hinged on the right side of the vertical sliding sleeve 424, and one end of the transmission rod 433 away from the vertical sliding sleeve 424 is rotatably installed on the rear side of the rotating plate 431.

[0045] The closing component 43 is used to push the plastic packaging tape raw material conveyed by the horizontal conveyor belt 12 to the right, so that the plastic packaging tape raw material can completely enter the crushing section 2 and be crushed by the crushing section 2, and the rotating plate 431 cooperates with the pressing rod 432 to prevent the crushing section 2 from throwing the shredded plastic packaging tape raw material to the left, thereby further improving the utilization rate of the plastic packaging tape raw material while ensuring the safety of the operator.

[0046] Specifically, as the vertical sleeve 424 reciprocates up and down, the transmission rod 433 will cause the rotating plate 431 to swing back and forth due to the drive of the vertical sleeve 424, so that the pressing rod 432 and the rotating plate 431 push the plastic packaging tape raw material on the horizontal conveyor belt 12 to the right and push it into the crushing part 2.

[0047] See also Figure 6 and Figure 8The crushing part 2 includes longitudinal notches arranged on two vertical sections of the U-shaped shell 1, and a square shell 21 is fixed on the two vertical sections of the U-shaped shell 1 and at the position of the longitudinal notches. A No. 1 motor 211 is installed on the front side of the square shell 21 through a motor box. The output section of the No. 1 motor 211 passes through the front side of the square shell 21 and is fixed with a rotating shaft 212 rotatably installed in the square shell 21. A plurality of herringbone moving knives 213 are evenly fixed on the side of the rotating shaft 212 in a circumferential direction. Two arc-shaped baffles 214 are fixed between the two vertical sections of the U-shaped shell 1, and each arc-shaped baffle 214 is provided with a fixed knife 22. A pulling component 23 for preventing the raw material from being twisted is provided on the top of the arc-shaped baffle 214 on the right.

[0048] The crushing section 2 mainly achieves the purpose of crushing the plastic packaging tape raw material through the cooperation of the herringbone movable knife 213 and the fixed knife 22, and the herringbone movable knife 213 can prevent the plastic packaging tape raw material from being entangled on the herringbone movable knife 213, thereby ensuring the crushing efficiency of the plastic packaging tape raw material by the herringbone movable knife 213 and the fixed knife 22, and the plastic packaging tape raw material can be pulled by the pulling component 23, thereby further avoiding the situation where the plastic packaging tape raw material is entangled on the herringbone movable knife 213.

[0049] Specifically, when the pressing rod 432 and the rotating plate 431 push the plastic packaging tape raw materials on the horizontal conveyor belt 12 into the crushing part 2, the No. 1 motor 211 is first controlled to drive the rotating shaft 212 and the herringbone movable knife 213 to rotate clockwise, and the herringbone movable knife 213 will drive the plastic packaging tape raw materials to rotate synchronously. When the plastic packaging tape raw materials are driven to the position of the fixed knife 22 by the herringbone movable knife 213, the fixed knife 22 will cooperate with the herringbone movable knife 213 to crush the plastic packaging tape raw materials, and due to the setting of the pulling component 23, when the herringbone movable knife 213 rotates to the position of the pulling component 23, the pulling component 23 will pull the plastic packaging tape raw materials that may be entangled on the herringbone movable knife 213, thereby preventing the plastic packaging tape raw materials from being entangled on the herringbone movable knife 213 and ensuring the crushing efficiency.

[0050] See also Figure 1 and Figure 8 The fixed knife 22 is slidably connected to the middle part of the arc baffle 214, the central angle corresponding to the arc baffle 214 on the left is smaller than the central angle corresponding to the arc baffle 214 on the right, the fixed knife 22 on the left is inclined, and the fixed knife 22 on the right is horizontally set; the opposite sides of the two vertical sections of the U-shaped shell 1 are fixed by a square plate 221, and the end of the fixed knife 22 close to the square plate 221 is fixed with a positioning rod 222 that penetrates the square plate 221, and a compression spring is connected between the end of the fixed knife 22 close to the square plate 221 and the square plate 221.

[0051] The fixed knife 22 is used to cooperate with the herringbone movable knife 213 to crush the plastic packaging tape raw material, mainly by the positions of the knife tips of the two to press, cut and crush the plastic packaging tape raw material as a whole. At the same time, since there may be hard debris in the plastic packaging tape raw material during the collection process, it is very easy to cause damage to the knife when the herringbone movable knife 213 and the fixed knife 22 press the plastic packaging tape raw material. Therefore, a compressed spring and a positioning rod 222 are used to achieve the purpose of automatically avoiding hard debris by the fixed knife 22.

[0052] See also Figure 6-Figure 9 The pulling component 23 includes a longitudinal groove 231 arranged at the top of the arc-shaped baffle 214 on the right side, a rotating block 232 is rotatably installed in the middle of the longitudinal groove 231, a torsion spring is arranged between the rotating block 232 and the longitudinal groove 231 to maintain the rotating block 232 vertical, and a plurality of limit sleeves 233 are evenly arranged longitudinally at the bottom of the rotating block 232, each limit sleeve 233 is slidably connected with a needle block 234, a connecting spring is connected between the needle block 234 and the rotating block 232, and all the needle blocks 234 are fixed with a synchronization rod 235; the front and rear inner walls of the square shell 21 are symmetrically fixed with arc-shaped guide plates 236 that cooperate with the synchronization rod 235 to push the needle block 234 away from the rotating block 232.

[0053] The pulling component 23 can be supported by the herringbone movable knife 213 to separate the plastic packaging tape material on the herringbone movable knife 213 from the herringbone movable knife 213, thereby avoiding the plastic packaging tape material being entangled on the herringbone movable knife 213, and the needle block 234 and the synchronization rod 235 cooperate with the arc guide plate 236 to pull the plastic packaging tape material on the herringbone movable knife 213 in a direction away from the herringbone movable knife 213.

[0054] Specifically, when the No. 1 motor 211 drives the rotating shaft 212 and the herringbone movable knife 213 to rotate clockwise, the herringbone movable knife 213 will push the needling block 234 to rotate to the right. As the needling block 234 rotates to the right, the synchronization rod 235 will move the needling block 234 away from the limiting sleeve 233 under the action of the trajectory of the arc guide plate 236, so that the needling block 234 pierces the plastic packaging tape raw material and pulls the plastic packaging tape raw material away from the herringbone movable knife 213.

[0055] The working steps of the present invention are as follows: In the first step, the operator takes out the plastic packaging tape raw materials placed in bags and places them on the horizontal conveyor belt 12, and then controls the horizontal conveyor belt 12 to transmit the plastic packaging tape raw materials from left to right. In the process of the plastic packaging tape raw materials moving from left to right, the second motor 411 is controlled to drive the power shaft 412 to rotate counterclockwise. Due to the rotation of the power shaft 412, the pressing pointed rod 413 will press and puncture the plastic packaging tape raw materials downward, thereby ensuring that the plastic packaging tape raw materials are close to the horizontal conveyor belt 12.

[0056] In the second step, as the No. 2 motor 411 drives the power shaft 412 to rotate counterclockwise, the power shaft 412 will drive the synchronous sleeve 311 to reciprocate up and down through the transmission component 42. When the synchronous sleeve 311 moves downward, the vertical moving plate 313 will drive the vertical moving block 314 and the lower pressure plate 315 to move downward together, so that the lower pressure plate 315 presses the plastic packaging tape raw material in the middle position of the horizontal conveyor belt 12 and makes the plastic packaging tape raw material close to the horizontal conveyor belt 12, and the concentrating component 32 will push the plastic packaging tape raw material at the edge position of the horizontal conveyor belt 12 to the middle position of the horizontal conveyor belt 12.

[0057] In the third step, when the compressed plastic packaging tape material moves to the rightmost end along with the horizontal conveyor belt 12, the transmission rod 433 will drive the rotating plate 431 to swing back and forth due to the transmission action of the transmission component 42, so that the pressing rod 432 and the rotating plate 431 push the plastic packaging tape material on the horizontal conveyor belt 12 to the right and push it into the crushing part 2.

[0058] In the fourth step, after the pressing rod 432 and the rotating plate 431 push the plastic packaging tape raw materials on the horizontal conveyor belt 12 into the crushing part 2, first control the No. 1 motor 211 to drive the rotating shaft 212 and the herringbone movable knife 213 to rotate clockwise, and the herringbone movable knife 213 will drive the plastic packaging tape raw materials to rotate synchronously. When the plastic packaging tape raw materials are driven to the position of the fixed knife 22 by the herringbone movable knife 213, the fixed knife 22 will cooperate with the herringbone movable knife 213 to crush the plastic packaging tape raw materials, and due to the setting of the pulling component 23, when the herringbone movable knife 213 rotates to the position of the pulling component 23, the pulling component 23 will pull the plastic packaging tape raw materials that may be wrapped around the herringbone movable knife 213.

[0059] In the fifth step, after the plastic packaging tape raw material is crushed, it will fall onto the oblique conveyor belt 13 and be transported to the upper right by the oblique conveyor belt 13 to complete the discharge. Then, the operator will collect and store the discharged plastic packaging tape fragments.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
