[0003] The existing high-efficiency crushing device for plastic product manufacturing has the following disadvantages: the existing device relies on two crushing columns for crushing operation during plastic processing to meet the daily basic needs. However, this single working mode has significant limitations, as it can only produce one form of plastic fragments. When the actual application scenario requires more finely crushed plastic particles, the current device with only two crushing columns is not up to the task and cannot complete the corresponding fine crushing task. INVENTION CONTENTS

[0005] The primary crushing structure comprises a crushing column rotatably connected to the inner wall of the charging box, a mounting frame assembled to the right side of the charging box, a driving motor mounted outside the mounting frame, and a first sprocket fixedly connected between the two crushing columns and located in the mounting frame.

[0006] Preferably, the output end of the driving motor extends to the inside of the mounting frame and is fixedly connected with one of the first sprockets.

[0007] Preferably, the screening structure comprises a servo motor and a second sprocket fixedly connected with the servo motor, and a screening plate located directly below the charging box, the outside of the second sprocket is meshingly connected with a second chain, and the inner wall of the second chain is meshingly connected with a third sprocket.

[0008] Preferably, a turntable is fixedly connected to the end of the second sprocket away from the servo motor, a connecting rod is rotatably connected to the outside of the turntable, slide rails are provided on both sides of the screening plate to limit the position of the screening plate and for its sliding, a fixing block is installed behind the screening plate, and the end of the connecting rod away from the turntable is rotatably connected to the inner wall of the fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the design of a primary crushing structure, a screening structure, and a secondary crushing structure, uses a drive motor to drive a first sprocket, which in turn causes two crushing columns to rotate synchronously in opposite directions via a first chain. This process initially crushes the plastic products loaded into the feeding box, breaking down large pieces of plastic. Subsequently, the plastic is screened through a screening structure. Fragments that do not meet the standards pass through a screening plate and enter a collection box. The high-speed rotation of the cutting column further cuts the plastic fragments that do not meet the fineness requirements after screening, producing finer plastic particles. This fully meets the diverse needs of different production stages for the fineness of plastic fragments, greatly improving production efficiency and product quality.

[0014] This invention achieves efficient power sharing and energy conservation through the transmission of sprockets and chains. The servo motor, as the main power source of the entire device, drives the second sprocket to rotate. The second sprocket drives the screening plate and, through the second chain, drives the third sprocket, causing the turntable connected to the second sprocket to drive the screening plate to reciprocate on the slide rail via a connecting rod, thereby screening the plastic fragments after the initial crushing. On the other hand, the third sprocket is connected to a round rod, transmitting power to the fifth sprocket. The fifth sprocket drives the fourth sprocket through the third chain, which in turn causes the cutting column in the collection box to rotate at high speed, performing secondary crushing on the plastic fragments that do not meet the fineness requirements after screening. Through this power sharing method, the device achieves energy conservation and reduces production costs while ensuring efficient crushing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a high-efficiency crushing device for manufacturing plastic products, including a loading box 1, a primary crushing structure 2 for crushing plastic products in one step is provided on the outside and inside of the loading box 1, and a screening structure 3 and a secondary crushing structure 4 are provided below the loading box 1.

[0023] The primary crushing structure 2 includes a crushing column 21 rotatably connected to the inner wall of the feeding box 1 and a mounting frame 22 assembled on the right side of the feeding box 1, a drive motor 23 mounted on the outside of the mounting frame 22, and a first sprocket 24 fixedly connected to the two crushing columns 21 and located inside the mounting frame 22, with the two first sprockets 24 meshing with each other.

[0024] The above scheme employs a primary crushing structure 2, a screening structure 3, and a secondary crushing structure 4. Driven by a motor 23, the first sprocket 24 rotates synchronously in opposite directions via a first chain, initially crushing the plastic products loaded into the loading box 1 and breaking down large pieces of plastic. The plastic is then screened by the screening structure 3. Fragments that do not meet the standards pass through the screening plate 33 into the collection box 41. The high-speed rotation of the cutting column 42 further cuts the screened plastic fragments that do not meet the required fineness, producing finer plastic particles. This comprehensively meets the diverse needs of different production stages for the fineness of plastic fragments, greatly improving production efficiency and product quality.

[0025] like Figures 1 to 5 As shown, the output end of the drive motor 23 extends into the interior of the mounting frame 22 and is fixedly connected to one of the first sprockets 24. The screening structure 3 includes a servo motor 31 and a second sprocket 32 ​​fixedly connected to the servo motor 31, as well as a screening plate 33 located directly below the loading box 1. The second sprocket 32 ​​is externally meshed with a second chain 34, and the inner wall of the second chain 34 is meshed with a third sprocket 35.

[0026] The above scheme achieves efficient power sharing and energy saving through the transmission of sprockets and chains. The servo motor 31, as a crucial power source for the entire device, drives the second sprocket 32. The second sprocket 32 ​​drives the screening plate 33, and the second chain 34 drives the third sprocket 35, causing the turntable 36 connected to the second sprocket 32 ​​to drive the screening plate 33 to reciprocate on the slide rail 38 via the connecting rod 37, thus screening the plastic fragments after initial crushing. Simultaneously, the third sprocket 35 is connected to the round rod 46, transmitting power to the fifth sprocket 45. The fifth sprocket 45 drives the fourth sprocket 43 through the third chain 44, which in turn causes the cutting column 42 in the collection box 41 to rotate at high speed, and performs secondary crushing on plastic fragments that do not meet the fineness requirements after screening. Through this power sharing method, the device achieves energy saving and reduces production costs while ensuring efficient crushing function. The side of the screening plate 33 away from the fixed block 39 is provided with an inclined groove, which allows large plastic pieces to gradually slide into the inclined groove and fall into the collection box 41. In subsequent production, a collection bag needs to be placed at the bottom of the screening plate 33 to collect the screened plastic fragments.

[0027] like Figures 1 to 5As shown, the second sprocket 32 ​​is fixedly connected to a turntable 36 at the end away from the servo motor 31. A connecting rod 37 is rotatably connected to the outside of the turntable 36. Slide rails 38 are provided on both sides of the screening plate 33 to limit the position of the screening plate 33 and for its sliding. A fixing block 39 is installed behind the screening plate 33. The end of the connecting rod 37 away from the turntable 36 is rotatably connected to the inner wall of the fixing block 39. The secondary crushing structure 4 includes a collection box 41 located below the screening plate 33 and a cutting column 42 located inside the collection box 41, as well as a fourth sprocket 43 fixedly connected to one end of the cutting column 42. A third chain 44 is meshed with the outside of the fourth sprocket 43.

[0028] Using the above scheme: when the turntable 36 rotates, the connecting rod 37 moves accordingly. Since the two sides of the screening plate 33 are restricted by the slide rail 38, the movement of the connecting rod 37 is converted into the reciprocating linear sliding of the screening plate 33 on the slide rail 38, which allows the screening plate 33 to work in a stable and regular manner and efficiently screen plastic fragments. The collection box 41 is located below the screening plate 33 and can directly receive plastic fragments that have not passed the screening and need to be further crushed.

[0029] like Figures 1 to 5 As shown, the inner wall of the third chain 44 is also meshed with a fifth sprocket 45. A round rod 46 for transmission is provided between the fifth sprocket 45 and the third sprocket 35. It also includes a support frame 5 located in the loading box 1 and used to support and fix its position. Two slide rails 38 are installed on the outer wall of the support frame 5. An extension block and a support rod 51 for fixing the position of the servo motor 31 are provided on the outside of the support frame 5. The end of the third sprocket 35 away from the fifth sprocket 45 is fixedly connected to one end of the support rod 51, and the other end of the support rod 51 is rotatably connected to the outer wall of the extension block.

[0030] The above solution is adopted: the support frame 5 is used to support and fix the position of the loading box 1, providing a stable foundation for the entire device. It can withstand the weight of the loading box 1 and the plastic products inside, as well as the vibration and impact generated during the operation of the equipment, ensuring that the device will not shake or tip over during operation, thus guaranteeing the safety and stability of the equipment. When the servo motor 31 drives the second sprocket 32 ​​to rotate, the third sprocket 35 is rotated through the chain drive, and then the power is transmitted to the fifth sprocket 45 through the round rod 46, which in turn drives the fourth sprocket 43 and the cutting column 42 to work. This means that only one power source, the servo motor 31, is needed to drive two key functional components, reducing the use of additional power equipment and reducing energy consumption and equipment costs.

[0031] The working principle of this utility model:

[0032] First, the plastic to be crushed is placed into the loading box 1. The drive motor 23 is started, and its output end drives the first sprocket 24 fixedly connected to it in the mounting frame 22 to rotate. Since the two first sprockets 24 mesh with each other, the two crushing columns 21 rotatably connected to the inner wall of the loading box 1 rotate synchronously in opposite directions, performing initial crushing of the plastic in the loading box 1, breaking down large pieces of plastic into smaller fragments. Then, the servo motor 31 is turned on, which drives the second sprocket 32 ​​fixedly connected to it to rotate. The second sprocket 32 ​​drives the third sprocket 35 to rotate through the second chain 34. At this time, the turntable 36 fixedly connected to the end of the second sprocket 32 ​​away from the servo motor 31 rotates accordingly. The connecting rod 37 rotatably connected to the outside of the turntable 36 is restricted by the slide rail 38 on the outer wall of the support frame 5 on both sides of the screening plate 33, causing the screening plate 33 to reciprocate on the slide rail 38. The device screens the plastic fragments after initial crushing. Fragments that meet the standards fall from the screening plate 33 and can be collected in a collection bag placed at the bottom of the screening plate 33. Larger fragments that do not meet the standards slide along the inclined groove on the screening plate 33 and eventually fall into the collection box 41 below the screening plate 33. At this time, the third sprocket 35 transmits power to the fifth sprocket 45 through the round rod 46. The fifth sprocket 45 then drives the fourth sprocket 43 to rotate through the third chain 44. The fourth sprocket 43 is fixedly connected to one end of the cutting column 42 inside the collection box 41, so that the cutting column 42 rotates at high speed, further cutting the plastic fragments that do not meet the fineness requirements after screening in the collection box 41, producing finer plastic particles that meet the needs of different production stages. Throughout the entire operation, the support frame 5 provides stable support for the device, ensuring the safe and stable operation of the equipment.
