Description

Technical Field

[0001] The invention relates to the technical field of carton raw material processing, and in particular to a raw material crusher for producing and processing packaging cartons. Background Art

[0002] Cartons are the most widely used packaging products. According to the materials used, they are divided into corrugated boxes, single-layer paperboard boxes, etc. They are light in weight and easy to carry and transport. Compared with other packaging materials, the production cost of cartons is relatively low. At the same time, cartons can be recycled and reused, which meets environmental protection requirements, and can protect the internal items from collision, extrusion and other damage to a certain extent. During the manufacturing process of cartons, the raw materials need to be crushed. Straws, wood, waste paper and wheat straw can all be used as raw materials for packaging cartons. The raw materials are crushed and processed into pulp to make packaging cartons. As an indispensable part of modern logistics, packaging cartons play an important role in containing, protecting products and appearance.

[0003] Since there are many types of raw materials for carton production, it is difficult to crush them completely at one time. After a long period of raw material crushing, more and more incompletely crushed raw materials are mixed with the completely crushed materials and piled up together, resulting in poor quality when subsequently processed into pulp. Therefore, we proposed a raw material crusher for packaging carton production and processing. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a raw material crusher for producing and processing packaging cartons, comprising:

[0005] A crushing box, wherein a feed hopper is arranged on the top of the crushing box;

[0006] A crushing roller, which is used to crush the raw materials poured into the feed hopper by roller pressure;

[0007] The re-crushing device is used to repeatedly crush the raw materials that are not completely crushed by the crushing rollers at one time, so as to prevent more and more incompletely crushed raw materials from mixing and piling up with the completely crushed materials, resulting in poor quality of pulp when subsequently processed;

[0008] A cleaning device, which is used to clean the raw material fragments remaining in the re-crushing device to prevent the incompletely crushed raw materials from being easily accumulated and causing blockage between the re-crushing device and the crushing roller when they are crushed for a long time;

[0009] The material pressing device is used to push and feed the raw materials accumulated in the feed hopper to prevent some objects with smooth surfaces or strange shapes from being difficult to insert into the two crushing rollers for a long time and being quickly crushed;

[0010] The top of the crushing box is connected to the bottom of the feed hopper, one end of the crushing roller is rotatably connected to the inner wall of the crushing box through a rotating bolt, one side of the re-crushing device is fixedly connected to the inner wall of the crushing box, the bottom of the re-crushing device is slidably connected to the top of the cleaning device, one end of the cleaning device is rotatably connected to the inner wall of the crushing device through a rotating bolt, and the inner wall of the feed hopper is slidably connected to one side of the pressing device;

[0011] Wherein, the re-crushing device comprises:

[0012] V-shaped arc plate, which has an inverted V-shaped plate body with an arc surface, is arranged at the bottom of the two crushing rollers with the same outer surface as the V-shaped arc plate to retain the raw materials that are not completely crushed and not broken between the crushing rollers and the V-shaped arc plate for repeated crushing, thereby preventing more and more raw materials that are not completely crushed from mixing and piling up with the completely crushed materials, resulting in poor quality of pulp when subsequently processed;

[0013] One side of the V-shaped arc plate is fixedly connected to the inner wall of the crushing box;

[0014] One end of the crushing roller is fixedly connected to a large motor, one end of the cleaning device is fixedly connected to a small motor, the bottom of the crushing box is fixedly connected to a bottom square shell, and the inner wall of the bottom square shell is slidably connected to a pull-out box;

[0015] The output end of the large motor is fixedly connected to the outer surface of the crushing box, and the output end of the small motor is fixedly connected to the outer surface of the crushing box;

[0016] The outer surface of the V-shaped arc plate is fixedly connected with a threaded arc block, and a plurality of threaded arc blocks matched with the crushing roller are arranged on the outer surface of the V-shaped arc plate to reduce the area of ​​the thread gap of the crushing roller, thereby preventing a part of the crushed raw materials from being torn by the roller pressure, and the short strip-shaped crushed materials are mixed in the thread gap of the crushing roller and are difficult to be crushed. The inner side of the V-shaped arc plate is provided with a square perforation, and the plurality of square perforations are arranged on the inner side of the V-shaped arc plate to facilitate screening of the crushed raw materials, and to prevent the completely crushed raw materials from still needing to be repeatedly crushed along the arc surface of the V-shaped arc plate before they can fall down and be discharged, affecting the crushing efficiency. The plurality of square perforations are arranged on the V-shaped arc plate to facilitate the completely crushed raw materials to fall down and be discharged in time, and to prevent the area between the V-shaped arc plate with a plurality of threaded arc blocks arranged on the surface and the crushing roller from being too small, resulting in the accumulation speed of the crushed raw materials being greater than the discharge speed, affecting the crushing effect.

[0017] There are multiple threaded arc blocks, and the multiple threaded arc blocks are evenly distributed on the V-shaped arc plate. There are multiple square perforations, and the multiple square perforations are evenly distributed on the inner side of the V-shaped arc plate. The square perforations penetrate the V-shaped arc plate and extend to the side of the threaded arc block close to the V-shaped arc plate.

[0018] Furthermore, the cleaning device comprises a long threaded rod, the outer surface of which is sleeved with a square scraper and threadedly connected thereto. When the square scraper moves, the inner side of the square scraper is scraped and cleaned to prevent the accumulated fine raw materials from falling downward for a long time, causing a large amount of dust to adhere to the inner side and accumulate, affecting the movement of the square scraper. Both sides of the square scraper are fixedly connected with corrugated ring sheets, and retractable corrugated ring sheets are arranged on both sides of the square scraper to wrap and cover the long threaded rod at all times, to prevent a large amount of dust and fine raw materials generated when the raw materials are crushed from accumulating on the thread surface of the long threaded rod and affecting the thread fit. The top of the square scraper is fixedly connected with an oblique thorn bar, which is always located in the square perforation as the square scraper moves, and performs puncturing and dredging in the square perforation to prevent the crushing after a long time. The finely crushed raw materials gradually accumulate in the square perforations, causing blockage, making it difficult to discharge the crushed raw materials in time. Hard brushes are fixedly connected to both sides of the square scraper. The movable hard brushes always wipe and clean the outer surface and threaded surface of the rotating crushing roller to prevent excessive dust and debris from adhering to the surface of the crushing roller after long-term use, causing excessive friction damage during extrusion and crushing and making it difficult to use for a long time. One end of the long threaded rod is rotatably connected to the inner wall of the crushing box through a rotating bolt, and one end of the long threaded rod is fixedly connected to the driving shaft of a small motor. The side of the corrugated ring sheet away from the square scraper is fixedly connected to the inner wall of the crushing box, and the top of the square scraper is slidably connected to the inner side of the V-shaped arc plate, and the top surface of the square scraper is set to an inverted V-shaped arc surface that fits the inner side of the V-shaped arc plate.

[0019] Furthermore, the material pressing device includes an inclined support plate, the top of the inclined support plate is fixedly connected to an electric push rod, the driving shaft of the electric push rod is fixedly connected to a long connecting plate, the side of the long connecting plate close to the electric push rod is fixedly connected to a thin connecting plate, the side of the thin connecting plate away from the long connecting plate is fixedly connected to a thin connecting rod, and the end of the thin connecting rod away from the thin connecting plate is fixedly connected to a V-shaped scraper, and at the same time, a pair of symmetrically arranged V-shaped scrapers are moved obliquely downward to push the accumulated raw materials between the two crushing rollers to prevent some objects with relatively smooth surfaces or peculiar shapes from being difficult to insert into the two crushing rollers for a long time and being quickly crushed, and the moving V-shaped scraper scrapes and cleans the inner wall of the feed hopper to prevent the surface from gradually accumulating after too much raw materials are placed in the feed hopper for a long time. Too much dust increases the friction loss of subsequent contact with raw materials. The V-shaped scraper is set to an inverted V shape, which makes it easier for the raw materials overflowing above the V-shaped scraper to slide along the V-shaped inclined surface to both sides into the feed hopper, thereby preventing a portion of the overflowed raw materials from accumulating above the V-shaped scraper and being difficult to fall into the feed hopper again and being crushed between the two crushing rollers. The outer surface of the V-shaped scraper is provided with inclined circular holes. By providing a plurality of inclined circular holes on the surface of the V-shaped scraper to reduce the contact area, it is difficult for the surface of the V-shaped scraper to accumulate too much dust, thereby preventing the V-shaped scraper from accumulating too much dust on the surface after long-term use, causing friction loss during multiple pushes and making it difficult to use for a long time. One side of the inclined support plate is fixedly connected to the outer side of the feed hopper, and one side of the V-shaped scraper is slidably connected to the inner wall of the feed hopper.

[0020] The present invention has the beneficial effects:

[0021] 1. The present invention arranges V-shaped arc plates at the bottom of the two crushing rollers that are consistent with their outer circular surfaces to retain the raw materials that are not completely crushed and not broken between the crushing rollers and the V-shaped arc plates for repeated crushing, thereby preventing more and more raw materials that are not completely crushed from mixing and piling up with the completely crushed materials, resulting in poor quality when subsequently processed into pulp. The oblique bar is always located in the square perforation as the square scraper moves, and punctures and clears the square perforation, thereby preventing the fine raw materials from gradually piling up in the square perforation after a long period of crushing, causing blockage and making it difficult for the crushed raw materials to be discharged in time. At the same time, a pair of symmetrically arranged V-shaped scrapers are moved obliquely downward to push the accumulated raw materials between the two crushing rollers, thereby preventing some objects with relatively smooth surfaces or peculiar shapes from being difficult to insert into the two crushing rollers for a long time and being quickly crushed.

[0022] 2. The present invention provides a re-crushing device, and provides a V-shaped arc plate at the bottom of the two crushing rollers that is consistent with the outer circular surface thereof to retain the raw materials that are not completely crushed and not broken between the crushing rollers and the V-shaped arc plate for repeated crushing, so as to prevent more and more raw materials that are not completely crushed from being mixed and piled up with the completely crushed materials, resulting in poor quality when subsequently processed into pulp; multiple threaded arc blocks that are compatible with the crushing rollers are provided on the outer surface of the V-shaped arc plate to reduce the area of ​​the thread gap of the crushing roller, so as to prevent a part of the crushed raw materials from being torn by the roller pressure, and the relatively long strip-shaped fragments that are not broken are mixed in the thread gap of the crushing roller and are difficult to be crushed; multiple square perforations are provided on the inner side of the V-shaped arc plate to facilitate screening of the crushed raw materials, and prevent the raw materials that have been completely crushed from still needing to be repeatedly crushed along the arc surface of the V-shaped arc plate before they can fall down and be discharged, thereby affecting the crushing efficiency; multiple square perforations are provided on the V-shaped arc plate to facilitate the timely falling and discharge of the completely crushed raw materials, and prevent the area between the V-shaped arc plate with multiple threaded arc blocks provided on the surface and the crushing roller from being too small, resulting in the accumulation speed of the crushed raw materials being greater than the discharge speed, thereby affecting the crushing effect.

[0023] 3. The present invention provides a cleaning device to scrape and clean the inner side surface of the square scraper when the square scraper moves, so as to prevent the accumulation of fine and broken raw materials that fall downward for a long time and cause a large amount of dust to adhere to the inner side surface and accumulate, affecting the movement of the square scraper; by arranging retractable corrugated ring sheets on both sides of the square scraper to wrap and cover the threaded long rod at all times, so as to prevent a large amount of dust and fine and broken raw materials generated when the raw materials are crushed from accumulating on the thread surface of the threaded long rod and affecting the thread fit; the oblique bar is always located in the square perforation as the square scraper moves and performs puncturing and dredging in the square perforation, so as to prevent the fine and broken raw materials from gradually accumulating in the square perforation after long-term crushing and causing blockage, making it difficult to discharge the crushed raw materials in time; the moving hard brush wipes and cleans the outer surface and thread surface of the rotating crushing roller at all times, so as to prevent the crushing roller from being attached to the surface of the roller after long-term use due to excessive dust and broken materials, causing excessive friction damage during extrusion and crushing and making it difficult to use for a long time.

[0024] 4. The present invention sets a material pressing device and moves a pair of symmetrically arranged V-shaped scrapers obliquely downward to push the accumulated raw materials between the two crushing rollers, so as to prevent some objects with relatively smooth surfaces or peculiar shapes from being difficult to insert into the two crushing rollers for a long time and being quickly crushed. The moving V-shaped scraper scrapes and cleans the inner wall of the feed hopper, so as to prevent excessive dust from gradually accumulating on the surface of the feed hopper after too much raw materials are placed in the feed hopper for a long time, thereby increasing the friction loss of subsequent contact with the raw materials. By setting the V-shaped scraper in an inverted V shape, it is convenient for the raw materials overflowing above the V-shaped scraper to slide along the V-shaped inclined surface to both sides into the feed hopper, so as to prevent a part of the overflowed raw materials from accumulating above the V-shaped scraper and being difficult to fall again between the two crushing rollers in the feed hopper and being crushed. By opening a plurality of inclined circular holes on the surface of the V-shaped scraper to reduce the contact area, it is difficult for the surface of the V-shaped scraper to accumulate too much dust, so as to prevent the surface of the V-shaped scraper from accumulating too much dust after long-term use, thereby preventing the friction loss caused by multiple pushing and making it difficult to use for a long time.

When in use , start the small motor 8 to drive the threaded long rod 501 to rotate. When the threaded long rod 501 rotates, it drives the square scraper 502 that is threadedly matched with it and in contact with the inner side surface of the V-shaped arc plate 401 to be locked and limited to move. When the square scraper 502 moves, the inner side surface of the square scraper 502 is scraped and cleaned. When the square scraper 502 moves, it pushes the corrugated ring piece 503 on one side to shrink the corrugation and pulls the corrugated ring piece 503 on the other side to stretch. By arranging retractable corrugated ring pieces 503 on both sides of the square scraper 502 to wrap and cover the threaded long rod 501 at all times, when the square scraper 502 moves, it drives the oblique bar 504 on the top and the hard brushes on both sides. 505 moves together, the oblique bar 504 is always located in the square perforation 403 as the square scraper 502 moves, and the square perforation 403 is punctured and cleared, the hard brush 505 is always in friction contact with the outer surface and thread surface of the crushing roller 3 as the square scraper 502 moves, and the moving hard brush 505 is always wiping and cleaning the outer surface and thread surface of the rotating crushing roller 3.

At the same time, the batches of raw materials are symmetrically pushed by the symmetrically arranged pressing devices 6. The raw materials are pushed between the two crushing rollers 3 by the pressing devices 6 in two opposite directions to be crushed. The raw materials crushed once by the crushing rollers 3 fall downward from between the two crushing rollers 3 and fall between the re-crushing device 4 and the crushing rollers 3 to be repeatedly crushed for a long time. At the same time, the small motor 8 is started to drive the cleaning device 5 to move at the bottom of the re-crushing device 4 and clean the residual raw materials in the re-crushing device 4. The raw materials that are completely crushed into fragments will fall downward into the drawer box 10 in the bottom square shell 9, and the raw materials will be crushed and collected for a long time. After the collection, the pull-out box 10 can be pulled out of the bottom square shell 9, and the collected crushed raw materials will be processed uniformly.

By arranging a V-shaped arc plate 401 in line with the outer surface of the two crushing rollers 3 at the bottom, the raw materials that are not completely crushed and not broken will be retained between the crushing rollers 3 and the V-shaped arc plate 401 for repeated crushing. By arranging a plurality of threaded arc blocks 402 that are compatible with the crushing rollers 3 on the outer surface of the V-shaped arc plate 401 to reduce the area of ​​the thread gap of the crushing rollers 3, the raw materials that are not finely crushed will pass through the square perforations 403 and fall downward into the pull-out box 10. By opening a V-shaped arc plate 401 on the inner side The plurality of square perforations 403 facilitate screening of the crushed raw materials. By providing the plurality of square perforations 403 on the V-shaped arc plate 401, the crushed raw materials can be promptly dropped and discharged. The small motor 8 is started to drive the threaded long rod 501 to rotate. When the threaded long rod 501 rotates, the square scraper 502 that is threadedly matched with the threaded long rod 501 and in contact with the inner side surface of the V-shaped arc plate 401 and is locked and limited is moved. When the square scraper 502 moves, the inner side surface of the square scraper 502 is scraped and cleaned.

By arranging retractable corrugated ring pieces 503 on both sides of the square scraper 502, the threaded long rod 501 is constantly pressed against the threaded long rod 501. 1 is wrapped and covered, and when the square scraper 502 moves, it drives the oblique thorn bar 504 on the top and the hard brushes 505 on both sides to move together. When the square scraper 502 moves, the oblique thorn bar 504 is always located in the square perforation 403 and performs puncturing and cleaning on the square perforation 403. When the square scraper 502 moves, the hard brush 505 is in friction contact with the outer surface and thread surface of the crushing roller 3 at all times. The moving hard brush 505 wipes and cleans the outer surface and thread surface of the rotating crushing roller 3 at all times. After a large amount of raw materials are put into the feed hopper 2, the electric push rod 602 drives the long connecting plate 603 to move obliquely downward. The movement of the long connecting plate 603 drives the inner thin connecting plate 604 and the thin connecting rod 605 to move obliquely downward together.When the thin connecting rod 605 moves, it drives the V-shaped scraper 606 at the bottom to move together, and at the same time, the symmetrically arranged pair of V-shaped scrapers 606 move diagonally downward to push the accumulated raw materials between the two crushing rollers 3. When the V-shaped scraper 606 moves diagonally downward, the side surface is always in contact with the inner wall of the feed hopper 2. The moving V-shaped scraper 606 scrapes and cleans the inner wall of the feed hopper 2. By setting the V-shaped scraper 606 in an inverted V shape, it is convenient for the raw materials overflowing above the V-shaped scraper 606 to slide along the V-shaped inclined surface to both sides into the feed hopper 2.
