Description

Technical Field

[0001] This invention relates to the field of calcium carbonate filler masterbatch technology, specifically a pelletizer for the production of calcium carbonate filler masterbatch. Background Technology

[0002] With the rising prices of plastic raw materials, calcium carbonate filler masterbatch has become increasingly popular in the plastics industry due to its abundant resources, low price, and superior performance. It offers numerous advantages, such as: reducing the cost of plastic products, improving production efficiency, and achieving good economic benefits; enhancing the rigidity and increasing the weight of plastic products; reducing shrinkage and deformation caused by shrinkage; excellent compatibility with polypropylene and polyethylene, thus maintaining a smooth appearance even with large filler volumes; high whiteness, allowing for flexible formulation to produce products in various colors; and the use of coupling agents and dispersants during processing, which helps maintain good mechanical properties even with large filler volumes.

[0003] For example, application number 202221810635.4 discloses a pelletizer for the production of calcium carbonate filler masterbatch, relating to the field of calcium carbonate filler masterbatch technology. It includes a machine body, with a traction component at the upper internal end, limiting components fixedly installed on both internal sides, a cutting component at the lower internal end, and a shock-absorbing component fixedly installed at the lower end of the support legs. This invention solves the problem of inefficient material loading by workers through the traction component, which provides traction and can compress materials into regular shapes, facilitating efficiency. The limiting components create a space for material movement, fixing and restricting the material's transport path. The cutting component can cut and trim at high speed and efficiency; its unique blade assembly forms a cross shape, facilitating continuous cutting. The shock-absorbing components reduce vibration during operation, making the pelletizer run more smoothly. However, this pelletizer is not convenient for screening the finished product after cutting, nor for collecting the screened product, and it is not convenient for automatically and quantitatively replenishing raw materials.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention, through the arrangement of a main body, a discharge trough, a slide rail, a filter plate, a motor, a cam, a buffer plate, a spring, a slide groove, a baffle, a fixing hole, a slot, a pin, a vertical plate, a slide rod, and a spring, allows the finished product cut by the main body to enter the discharge trough and be filtered by the filter plate. During filtration, the motor drives the cam to rotate, and the rotation of the cam pushes the filter plate to one side. It cooperates with the buffer plate and spring at the other end to make the filter plate vibrate, thereby accelerating the filtration efficiency and improving the working efficiency of the device.

[0018] 2. This invention, through the arrangement of a tray, spring three, flap one, base, inclined plate, conveyor belt one, elastic component, mounting plate, roller, and conveyor belt two, allows the finished product to fall onto the inclined plate after filtering and eventually accumulate above flap one. When collecting the finished product, the collection box is directly placed into conveyor belt two. Under the action of conveyor belt two, the collection box can push flap one above it and simultaneously position it on the mounting plate. In this way, the finished product above flap one can be collected. When a certain weight is collected, the mounting plate falls, so that the lower end of the collection box contacts conveyor belt one. When conveyor belt one transports the collection box away, flap one is reset under the action of spring three to prevent the finished product from falling and scattering, thereby reducing the waste of finished product.

[0019] 3. This invention, through the arrangement of a base plate, sleeve, bolts, spring four, slide rod two, threading rod, hopper, outer shell, transmission belt three, spring five, hinged plate two, limiting block, threading hole, roller, and slide groove two, allows workers to directly place raw materials into the lower end of the outer shell during feeding. The materials are then transported to the top of the hopper via transmission belt three. After the raw materials in the hopper are used up, the hopper is lifted by spring four. When the hopper returns to its original position, the cable is released. Spring five then opens hinged plate two, allowing raw materials to enter the hopper. Once a certain weight is reached, the hopper is pressed down, and the cable, through hinged plate two, clamps the raw materials, preventing excessive material from entering the hopper and causing blockage, thus simplifying the operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-3 As shown, a pelletizer for producing calcium carbonate filler masterbatch includes a main body 1. A discharge trough 2 is fixedly installed at the lower end of the main body 1, and a slide rail 3 is fixedly installed in the middle of the discharge trough 2. Two slide rails 3 are symmetrically arranged along the center line of the discharge trough 2 and pass through the discharge trough 2. A filter plate 4 is slidably installed in the middle of the slide rail 3, and a motor 5 is installed on the lower side of one end of the filter plate 4. The motor 5 is fixedly connected to the main body 1. A cam 6 is fixedly installed on the upper end of the motor 5, and two motors 5 are symmetrically arranged along the center line of the discharge trough 2. A buffer plate 7 is installed at the other end of the filter plate 4 and is slidably connected to the discharge trough 2. The buffer plates 7 are set as a set of two. The finished product cut by the main body 1 enters the discharge trough 2 and can be filtered by the filter plate 4. During filtration, the motor 5 drives the cam 6 to rotate. The rotation of the cam 6 pushes the filter plate 4 to one side and cooperates with the buffer plate 7 and spring 8 at the other end to make the filter plate 4 vibrate, thereby speeding up the filtration efficiency and improving the working efficiency of the device.

[0028] Furthermore, the filter plate 4 can be replaced with different specifications according to different usage requirements. When replacing the filter plate 4, first pull open the vertical plate 14 so that the pin 13 disengages from the slot 12, and then slide the baffle 10 to one side. After the baffle 10 slides out, the filter plate 4 can be taken out and replaced, so as to improve the adaptability of the device.

[0029] like Figure 2 , Figures 3-5As shown, a spring 8 is fixedly installed between the buffer plates 7. Slide grooves 9 are provided on both sides of the filter plate 4 inside the discharge trough 2. A baffle 10 is slidably installed inside the slide groove 9, and a fixing hole 11 is provided in the middle of one side of the baffle 10. A slot 12 is provided at the rear end of the fixing hole 11 through the discharge trough 2, and a pin 13 is slidably installed in the middle of the slot 12. A vertical plate 14 is fixedly installed at the other end of the pin 13, and slide rods 15 are fixedly installed on both sides of the vertical plate 14. The slide rods 15 are fixedly connected to the vertical plate 14. A spring 16 is fixedly installed at the other end of the slide bar 15. The other end of the spring 16 is also fixedly connected to the discharge chute 2. A tray 17 is fixedly installed on one side of the lower end of the discharge chute 2. A hinged plate 19 is slidably installed inside the tray 17. The other end of the hinged plate 19 is fixedly connected to a spring 18. The other end of the spring 18 is fixedly connected to the tray 17. A base 20 is installed at the lower end of the main body 1. An inclined plate 21 is fixedly installed on the upper end of the base 20 on one side of the discharge chute 2. A conveyor belt is installed in the middle of one side of the base 20. Conveyor belt 22 has elastic components 23 fixedly installed at both ends. The lower end of the elastic component 23 is fixedly connected to the base 20, and the upper end of the elastic component 23 is fixedly installed with a mounting plate 24. Four elastic components 23 are symmetrically arranged along the center line of the mounting plate 24. A roller 25 is rotatably installed on the upper end of the mounting plate 24. A second conveyor belt 26 is installed above the first conveyor belt 22 on one side of the mounting plate 24. The second conveyor belt 26 passes through one side of the base 20. After the finished product is filtered, it falls onto the inclined plate 21 and finally onto the movable plate 1. When collecting finished products, the collection box is placed directly into the conveyor belt 26. Under the action of the conveyor belt 26, the collection box can push the upper flap 19 and simultaneously be positioned on the mounting plate 24. This can collect the finished products above the flap 19. When a certain weight is collected, the mounting plate 24 falls, so that the lower end of the collection box contacts the conveyor belt 22. When the conveyor belt 22 transports the collection box away, the flap 19 is reset under the action of the spring 3 18 to prevent the finished products from falling and scattering, thereby reducing the waste of finished products.A base plate 27 is fixedly installed around the upper perimeter of the main body 1, and four base plates 27 are symmetrically arranged along the center line of the main body 1. A sleeve 28 is fixedly installed in the middle of the upper end of the base plate 27, and a bolt 29 is slidably installed inside the sleeve 28. The bolt 29 engages with the base plate 27, and a spring 30 is rotatably installed at the upper end of the bolt 29. A sliding rod 31 is fixedly installed at the upper end of the spring 30, and the sliding rod 31 is slidably connected to the sleeve 28. The base plate 27 is also fixedly installed at the upper end of the sliding rod 31, and a threading rod 32 is fixedly installed at the upper end of the base plate 27. A hopper 33 is installed inside the base plate 27 at the upper end of the main body 1, and the upper and lower ends of the hopper 33 are fixedly connected to the base plate 27 and the main body 1, respectively. A shell 34 is installed on one side above the hopper 33, and a transmission belt 35 is installed inside the shell 34 on the side away from the hopper 33. The transmission belt 35 passes through the interior of the shell 34. A spring 36 is fixedly installed inside the upper end of the outer shell 34, and two springs 36 are symmetrically arranged along the center line of the outer shell 34. A hinged plate 37 is fixedly installed at the other end of the spring 36, and the hinged plate 37 is slidably connected to the outer shell 34. A sliding groove 41 is opened on both sides of the outer shell 34, and the sliding groove 41 is symmetrical about the upper end of the outer shell 34. The sliding groove 41 is slidably connected to the hinged plate 37, and a limit block 38 is fixedly installed inside the sliding groove 41 at the front end of the hinged plate 37. A wire hole 39 is opened at the upper end of the limit block 38, and a roller 40 is set on the side of the limit block 38 away from the hinged plate 37. The roller 40 is rotatably connected to the sliding groove 41. When feeding, the worker directly puts the raw material into the lower end of the outer shell 34, and it is transported to the top of the hopper 33 by the transmission belt 35. After the raw material in the hopper 33 is used up, the hopper 33 is lifted by the action of the spring 40. When the hopper 33 is reset, the cable is released. The spring 36 opens the flap 37, allowing the material above to enter the hopper 33. Once a certain weight is reached, the hopper 33 is pressed down, causing the flap 37 to clamp the material via a cable. This prevents excessive material from entering the hopper 33 and causing blockage, thus simplifying the operation.

[0030] Furthermore, the bolt 29 can be rotated to move along the thread direction, thus changing the stroke range of the spring 30 and adjusting the weight of the raw materials it can withstand.

[0031] Working Principle: When using this pelletizer for calcium carbonate filler masterbatch production, firstly, the finished product cut by the main body 1 enters the discharge trough 2 and is filtered through the filter plate 4. During filtration, the motor 5 drives the cam 6 to rotate, pushing the filter plate 4 to one side. This, in conjunction with the buffer plate 7 and spring 8 at the other end, causes the filter plate 4 to vibrate, thereby accelerating the filtration efficiency and improving the working efficiency of the device. Secondly, after filtration, the finished product falls onto the inclined plate 21 and eventually accumulates above the movable plate 19. When collecting the finished product, the collection box is directly placed into the conveyor belt 26. Under the action of the conveyor belt 26, the finished product can be... The collection box pushes the upper flap 19 and simultaneously positions it on the mounting plate 24. This allows the finished products above the flap 19 to be collected. When a certain weight is collected, the mounting plate 24 falls, causing the lower end of the collection box to contact the conveyor belt 22. As the conveyor belt 22 transports the collection box away, the flap 19 resets under the action of the spring 38, preventing finished products from falling and scattering, thus reducing waste. Finally, during loading, the worker directly places the raw materials into the lower end of the outer casing 34, which is then transported to the top of the hopper 33 via the transmission belt 35. After the raw materials in the hopper 33 are used up, the hopper 33 is lifted by the action of the spring 40. When the hopper 33 resets, the cable is released. The flap 27 opens under the action of the spring 5 36, allowing the raw materials above to enter the hopper 33. When a certain weight is reached, the hopper 33 is pressed down, and the cable drives the flap 2 37 to clamp the raw materials, preventing excessive material from entering the hopper 33 and causing blockage, thus simplifying the operation. This is the working principle of the pelletizer used for producing calcium carbonate filler masterbatch.
