Description

Technical Field

[0001] The invention belongs to the technical field of plastic product production, in particular to a raw material cleaning device for plastic product production. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. During the production process of plastic products, the plastic raw materials need to be cleaned before processing.

[0003] The utility model patent with the announcement number CN216126213U discloses a raw material cleaning device for the production of plastic products, wherein a cleaning cylinder is provided inside the box body, the cleaning cylinder includes a fixed ring and a rotating filter cylinder, the coarser end of the rotating filter is rotatably connected to the fixed ring, a rotating support shaft is provided inside the cleaning cylinder, and the ends of the two rotating filter cylinders that are away from each other are fixedly connected to the rotating support shaft; and a clearing device is provided on both side walls of the box body. Compared with the prior art, the utility model has the following advantages: water is injected into the box body, the cleaning cylinder rotates, driving the plastic particles to pass through the water, and the plastic particles are rinsed and washed. The plastic particles are driven to flip by the cleaning cylinder, and friction is generated between them to loosen the dust, making it easier to clean. After cleaning, the water is discharged, and the cleaning cylinder rotates again to cause the water to be thrown out by centrifugal force, reducing the water adhering to the plastic particles, avoiding the water from absorbing dust, and saving the drying time at the same time. A clearing device is provided on both side walls of the box body to avoid the mesh of the rotating filter cylinder from being blocked.

[0004] However, the above technical solution still has the following deficiencies in practical application: Although the water can be drained after cleaning, and then the cleaning cylinder can be driven to rotate, and the residual water on the surface of the raw material can be thrown out through the mesh under the action of centrifugal force, so as to reduce the water adhering to the plastic particles, avoid the water adsorbing dust, and save drying time. However, when the water is discharged from the cleaning cylinder, it will be discharged together with the dust. Therefore, some dust will adhere to the hole wall of the mesh, and even cause the mesh to be blocked, resulting in some water being unable to pass through the mesh during the subsequent throwing-out work, thereby affecting the effect of throwing out the water on the surface of the plastic raw material.

[0005] To this end, the present invention provides a raw material cleaning device for producing plastic products. Summary of the invention

A motor 6 42 is fixedly connected to the front end of the upper side of the right end surface of the cleaning box 1, and the output end of the motor 6 42 is fixedly connected to the right end of the bidirectional threaded rod 40; Specifically, plastic is a polymer compound polymerized by addition polymerization or condensation polymerization with monomers as raw materials. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. During the production and manufacturing process of plastic products, the plastic raw materials before processing need to be cleaned. When the existing plastic product raw material cleaning device is used, although the water can be discharged after the cleaning is completed, and then the cleaning cylinder 37 is driven to rotate, under the action of centrifugal force, the residual water on the surface of the raw material is thrown out through the mesh to reduce the water adhering to the plastic particles, avoid the water adsorbing dust, and save drying time. However, when the water is discharged from the cleaning cylinder 37, it will be discharged together with the dust. Therefore, part of the dust will adhere to the hole wall of the mesh, and even cause the mesh to be blocked, resulting in the water being unable to pass through the mesh during the subsequent throwing-out work, thereby affecting the throwing-out effect of the water on the surface of the plastic raw material; Therefore, in order to solve the above problems, when using the present embodiment, the plastic raw material to be cleaned is first added into the cleaning cylinder 37, and then the motor 6 42 is started to drive the bidirectional threaded rod 40 to rotate, so that the shells 35 on the left and right sides move simultaneously and approach each other until the two shells 35 are meshed with each other, so that the through hole 38 on the cleaning cylinder 37 can be covered, and the two shells 35 after being fitted together will not affect the rotation of the cleaning cylinder 37, and then the cleaning water is added into the cleaning cylinder 37, so that a cleaning chamber can be formed under the cooperation of the two shells 35, and then the motor 7 41 is started to rotate the cylinder cover 36, so that the cylinder cover 36 is fitted with the upper end of the cleaning cylinder 37 to complete the closing of the cylinder cover 36, and then the motor 5 44 is started to drive the cleaning cylinder 37 to rotate, so that the plastic raw material inside the cleaning cylinder 37 is turbulent, so as to clean the plastic raw material; When the plastic raw material has been cleaned for a sufficient time, the cleaning cylinder 37 is driven to stop rotating, and then the two shells 35 are driven to separate again, so that the water in the cleaning cylinder 37 and the shell 35 is discharged, and the cylinder cover 36 is opened again, and the motor 13 is started to drive the gear 12 to rotate, and the threaded rod 14 can be rotated with the cooperation of the gear 25, and the lifting plate 7 is lowered, so that the bottom of the baffle 16 contacts the upper edge of the cleaning cylinder 37, and the upper edge of the cleaning cylinder 37 is an inclined surface, so when the lifting plate 7 is lowered, the outer side of the baffle 16 is fitted with the inner side of the cleaning cylinder 37, and the baffle 2 17 will be against the upper end of the cleaning cylinder 37, so that the slide bar 3 19 slides into the inner cavity of the sleeve 18, and the spring 21 is compressed until the baffle 2 17 and The outer sides of baffle plate 16 are against the inner wall of cleaning cylinder 37. When baffle plate 16 and baffle plate 2 17 are lowered, baffle plate 16 will squeeze the plastic material attached to the inner wall of cleaning cylinder 37, so that the plastic material attached to the inner wall of cleaning cylinder 37 is away from the inner wall of cleaning cylinder 37. At the same time, baffle plate 2 17 will also be inserted into the plastic material until the bottom of baffle plate 16 and baffle plate 2 17 are attached to the bottom of the inner cavity of cleaning cylinder 37. Then, motors 2 14 on both sides are started at the same time, and drive connecting rod 13 to rotate. When the angle between connecting rod 13 and connecting rod 2 15 changes, baffle plate 16 can be moved, and L-shaped rod 12 can slide on limit block 11 to move baffle plate 16 in the direction away from the inner wall of cleaning cylinder 37, so as to clean the plastic material. The plastic particles are pushed. At the same time, under the action of the spring 21, the baffle plate 2 17 will always be against the inner wall of the cleaning cylinder 37, and the slide rod 3 19 will extend from the sleeve 18, so that a fence can be formed under the cooperation of the baffle plate 16 and the baffle plate 2 17. There are no plastic particles in this fence. Then the motor 3 23 is started to drive the threaded rod 2 9 to rotate, so that the mounting plate 24 moves on the threaded rod 2 9 and the slide rod 2 10, so that the mounting plate 24 is lowered, and the displacement column 28 is extended into the enclosure until the multiple dredging rods 29 are aligned with the multiple through holes 38 in a row of the cleaning cylinder 37. Then the electric push rod 25 is used to drive the rectangular block 26 to rise, so that the connecting rod 3 27 drives the displacement column 28 to slide on the mounting plate 24, so that the dredging rod 29 passes through The through hole 38 can be pushed down by the dust attached to the hole wall of the through hole 38, and then the dredging rod 29 is driven to extend from the through hole 38 and reset upward, and then the cleaning cylinder 37 is driven to rotate, so that the next row of through holes 38 moves to the position where the previous row of through holes 38 is located, and during the rotation of the cleaning cylinder 37, the motor 4 33 is started and drives the threaded rod 32 to rotate, so that the scraper 31 moves on the threaded rod 32 and the sliding rod 4 30, so that the scraper 31 uses its edge to be flush with the end of the dredging rod 29 to scrape off the dust attached to the end of the dredging rod 29, so as to prevent the dust attached to the end of the dredging rod 29 from falling into the cleaning cylinder 37 again when the dredging rod 29 is dredging the next row of through holes 38, and the recycling effect is good;Then repeat the above operation to push off the dust attached to the walls of the through holes 38. After the dust on the walls of the through holes 38 is removed, the cylinder cover 36 is driven to close the upper end of the cleaning cylinder 37, and the cleaning cylinder 37 is driven to rotate again. Under the action of centrifugal force, the water remaining on the surface of the plastic particles can be thrown out, thereby reducing the water adhering to the plastic particles, preventing the water from absorbing dust, and saving the subsequent drying time of the plastic particles. Therefore, by using the anti-raw material covering dredging mechanism, before using the cleaning cylinder 37 to throw out the residual water on the surface of the plastic particles, the dredging rod 29 can pass through the through holes 38 in sequence to remove the dust attached to the wall of the through hole 38, so as to avoid the situation that the dust blocks the through hole 38 and affects the effect of throwing out the water. In addition, before the dredging rod 29 enters the cleaning cylinder 37, the plastic raw material near the through hole 38 can be pushed, and under the action of the baffle 1 16 and the baffle 2 17, a fence is formed so that there is no plastic raw material within the fence, so as to avoid the dredging rod 29 squeezing the plastic raw material during the dredging process and causing damage to the plastic raw material, thereby playing a protective effect on the plastic raw material. In addition, after the dredging rod 29 completes a dredging action, the dust attached to its end can be scraped off, so as to avoid the situation that the dust attached to the end of the dredging rod 29 falls into the cleaning cylinder 37 again during the subsequent dredging, thereby avoiding repeated contamination of dust and achieving a good recycling effect.

[0026] In this embodiment, Fig. 9 As shown, a drain pipe 8 is provided at the middle of the lower end of the right side of the cleaning box 1, and a valve is provided on the drain pipe 8; Specifically, after the cleaning water is discharged from the cleaning cylinder 37, it will be filtered through the filter 45. The filtered water will be at the bottom of the inner cavity of the cleaning box 1. Then the valve at the drain pipe 8 can be opened to discharge the filtered cleaning water. The cleaning water can be recycled, which saves water resources.

[0027] Working principle: first add the plastic raw material to be cleaned into the cleaning cylinder 37, then start the motor six 42 to drive the bidirectional threaded rod 40 to rotate, so that the shells 35 on the left and right sides move simultaneously and approach each other until the two shells 35 mesh with each other, so that the through hole 38 on the cleaning cylinder 37 can be covered, and the two shells 35 after fitting will not affect the rotation of the cleaning cylinder 37, then add cleaning water into the cleaning cylinder 37, and a cleaning chamber can be formed under the cooperation of the two shells 35, then start the motor seven 41 to rotate the cylinder cover 36, so that the cylinder cover 36 fits with the upper end of the cleaning cylinder 37, and the cylinder cover 36 is closed, and then start the motor five 44 to drive the cleaning cylinder 37 to rotate, so that the plastic raw material inside the cleaning cylinder 37 surges, so as to clean the plastic raw material;When the plastic raw material has been cleaned for a sufficient time, the cleaning cylinder 37 is driven to stop rotating, and then the two shells 35 are driven to separate again, so that the water in the cleaning cylinder 37 and the shell 35 is discharged, and the cylinder cover 36 is opened again, and the motor 13 is started to drive the gear 12 to rotate, and the threaded rod 14 can be rotated with the cooperation of the gear 25, and the lifting plate 7 is lowered, so that the bottom of the baffle 16 contacts the upper edge of the cleaning cylinder 37, and the upper edge of the cleaning cylinder 37 is an inclined surface, so when the lifting plate 7 is lowered, the outer side of the baffle 16 is fitted with the inner side of the cleaning cylinder 37, and the baffle 2 17 will be against the upper end of the cleaning cylinder 37, so that the slide bar 3 19 slides into the inner cavity of the sleeve 18, and the spring 21 is compressed until the baffle 2 17 and The outer sides of baffle plate 16 are against the inner wall of cleaning cylinder 37. When baffle plate 16 and baffle plate 2 17 are lowered, baffle plate 16 will squeeze the plastic material attached to the inner wall of cleaning cylinder 37, so that the plastic material attached to the inner wall of cleaning cylinder 37 is away from the inner wall of cleaning cylinder 37. At the same time, baffle plate 2 17 will also be inserted into the plastic material until the bottom of baffle plate 16 and baffle plate 2 17 are attached to the bottom of the inner cavity of cleaning cylinder 37. Then, motors 2 14 on both sides are started at the same time, and drive connecting rod 13 to rotate. When the angle between connecting rod 13 and connecting rod 2 15 changes, baffle plate 16 can be moved, and L-shaped rod 12 can slide on limit block 11 to move baffle plate 16 in the direction away from the inner wall of cleaning cylinder 37, so as to clean the plastic material. The plastic particles are pushed. At the same time, under the action of the spring 21, the baffle plate 2 17 will always be against the inner wall of the cleaning cylinder 37, and the slide rod 3 19 will extend from the sleeve 18, so that a fence can be formed under the cooperation of the baffle plate 16 and the baffle plate 2 17. There are no plastic particles in this fence. Then the motor 3 23 is started to drive the threaded rod 2 9 to rotate, so that the mounting plate 24 moves on the threaded rod 2 9 and the slide rod 2 10, so that the mounting plate 24 is lowered, and the displacement column 28 is extended into the enclosure until the multiple dredging rods 29 are aligned with the multiple through holes 38 in a row of the cleaning cylinder 37. Then the electric push rod 25 is used to drive the rectangular block 26 to rise, so that the connecting rod 3 27 drives the displacement column 28 to slide on the mounting plate 24, so that the dredging rod 29 passes through The through hole 38 can be pushed down by the dust attached to the hole wall of the through hole 38, and then the dredging rod 29 is driven to extend from the through hole 38 and reset upward, and then the cleaning cylinder 37 is driven to rotate, so that the next row of through holes 38 moves to the position where the previous row of through holes 38 is located, and during the rotation of the cleaning cylinder 37, the motor 4 33 is started and drives the threaded rod 32 to rotate, so that the scraper 31 moves on the threaded rod 32 and the sliding rod 4 30, so that the scraper 31 uses its edge to be flush with the end of the dredging rod 29 to scrape off the dust attached to the end of the dredging rod 29, so as to prevent the dust attached to the end of the dredging rod 29 from falling into the cleaning cylinder 37 again when the dredging rod 29 is dredging the next row of through holes 38, and the recycling effect is good;Then, the above operation is repeated to push off the dust attached to the walls of the multiple through holes 38. After the dust on the walls of the multiple through holes 38 is removed, the barrel cover 36 is driven to close the upper end of the cleaning barrel 37, and the cleaning barrel 37 is driven to rotate again, so that the water remaining on the surface of the plastic particles can be thrown out under the action of centrifugal force, so as to reduce the water adhering to the plastic particles, avoid the water adsorbing dust, and save the subsequent drying time of the plastic particles; thus, the anti-raw material covering dredging mechanism can be used to remove the dust attached to the walls of the through holes 38 by passing the dredging rod 29 through the through holes 38 in turn before the cleaning barrel 37 is used to throw out the water remaining on the surface of the plastic particles, so as to avoid the situation where dust blocks the through holes 38 and affects the water throwing effect, and before the dredging rod 29 enters the cleaning barrel 37, the plastic raw material near the through hole 38 can be cleaned. Push, and under the action of baffle plate 16 and baffle plate 2 17, a fence is formed, so that there is no plastic raw material in the fence range, which can prevent the dredging rod 29 from squeezing the plastic raw material during the dredging process and causing damage to the plastic raw material, and play a protective effect on the plastic raw material. In addition, after the dredging rod 29 completes a dredging action, the dust attached to the end of the dredging rod 29 can be scraped off to prevent the dust attached to the end of the dredging rod 29 from falling into the cleaning cylinder 37 again during the subsequent dredging, thereby avoiding repeated contamination of dust and having a good recycling effect. When the cleaning water is discharged from the cleaning cylinder 37, it will be filtered through the filter screen 45, and the filtered water will be at the bottom of the inner cavity of the cleaning box 1. Then, the valve at the drain pipe 8 can be opened to discharge the filtered cleaning water, so that the cleaning water can be recycled, which saves water resources. ;
