Description

Technical Field

[0001] This utility model belongs to the field of stiffening masterbatch production and processing technology, specifically relating to a crushing device for stiffening masterbatch. Background Technology

[0002] In the production and processing of stiffening masterbatch, the crushing process is one of the key steps. Its purpose is to process the masterbatch, which is in the form of large lumps or particles, into fine particles with uniform particle size, so that subsequent processes such as mixing and granulation can proceed smoothly. However, the stiffening masterbatch crushing equipment currently on the market still has many technical defects in practical applications, making it difficult to meet the requirements of efficient, stable, and precise production. These problems have become the main bottlenecks restricting the improvement of production efficiency and product quality.

[0003] During the production of stiffening masterbatch, there are significant differences in its initial morphology and particle size. Some devices can only pre-treat masterbatch of a single specification. If the masterbatch particle size is too large, insufficient pre-treatment may occur, leading to increased crushing load and reduced crushing efficiency in subsequent processes. If the masterbatch particle size is too small, excessive crushing may result in material waste and excessive dust pollution. In addition, in some pre-treatment devices, masterbatch tends to accumulate on the processing platform, failing to distribute evenly and further affecting the pre-treatment effect, creating potential problems for subsequent crushing processes. Therefore, those skilled in the art provide a crushing device for stiffening masterbatch to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed crushing device for stiffening masterbatch in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A crushing device for stiffening masterbatch includes a base, a crushing chamber and a pre-treatment crushing chamber are provided on the top of the base, the discharge port of the pre-treatment crushing chamber is connected to the feed port of the crushing chamber, a crushing platform is movably connected to the inner side wall of the pre-treatment crushing chamber, and a crushing roller is movably connected to the upper part of the crushing platform inside the pre-treatment crushing chamber.

[0007] As a further optimization of this utility model, a second servo motor is fixedly installed on the side wall of the pretreatment crusher box. The output end of the second servo motor rotates through the side wall of the pretreatment crusher box and is fixedly connected to the center position of the side wall of the crushing platform.

[0008] As a further optimization of this utility model, recesses are slidably connected to both sides of the inner wall of the pretreatment crusher box and above the crushing platform. The two recesses are symmetrically distributed, and the crushing roller is movably connected between the two recesses. Cylinders are fixedly installed on the top of the pretreatment crusher box and at the front and rear sides above the recesses. The output end of the cylinder is fixedly connected to the top of the recesses.

[0009] As a further optimization of this utility model, the side wall of the pretreatment crusher box is provided with a movable groove for the lifting and lowering of the crushing roller and the matching concave block. One end of the crushing roller is fixedly connected to a rotating rod, and one end of the rotating rod passes through the side wall of the corresponding concave block. A displacement plate is slidably sleeved on the outer side wall of one end of the rotating rod, and a third servo motor fixedly installed on the side wall of the displacement plate and fixedly connected to one end of the rotating rod.

[0010] As a further optimization of this utility model, the inner sidewall of the crusher box is rotatably connected to two cooperating crushing rollers on both sides. One end of each of the two crushing rollers is fixedly connected to a transmission rod. The outer sidewall of each of the two transmission rods is fixedly fitted with a transmission gear. The two transmission gears mesh with each other. One end of any of the transmission rods is fixedly connected to a first servo motor installed on the top of the base.

[0011] As a further optimization of this utility model, a protective cover is fixedly installed on the top of the crusher box and above the two transmission gears; a feeding port communicating with the feeding end of the pretreatment crusher box is fixedly installed on the top of the pretreatment crusher box; and a screen plate is fixedly installed on the inner side wall of the crusher box and below the two crushing rollers.

[0012] As a further optimization of this utility model, a chute is provided on the top of the base and below the discharge end of the crusher box, and a receiving box for receiving materials is slidably connected on the chute.

[0013] As a further optimization of this utility model, a controller is installed on the base, and the controller is electrically connected to the first servo motor, the third servo motor, the second servo motor and the four cylinders respectively.

[0014] The present invention is as follows:

[0015] 1. In this utility model, four cylinders on the top of the pre-treatment crusher can push concave blocks to move the crushing rollers up and down. With the space avoidance of the movable groove on the side wall, the distance between the crushing rollers and the crushing platform can be precisely adjusted according to the initial size of the masterbatch. At the same time, the second servo motor drives the crushing platform to tilt, ensuring that the masterbatch can be fed into the crusher. Compared with the prior art, this structure realizes dynamic adaptation of pre-treatment parameters, avoids the problem of poor pre-treatment effect caused by masterbatch accumulation or improper spacing, lays a better foundation for subsequent crushing processes, and improves the overall crushing quality stability.

[0016] 2. In this utility model, the first servo motor drives the crushing roller to rotate in the opposite direction through two meshing transmission gears. The gear meshing transmission ensures that the power transmission is not delayed. Compared with belt transmission and other methods, it reduces transmission loss and improves crushing efficiency. At the same time, the protective cover on the top of the crusher box completely isolates the transmission gears, preventing dust and foreign objects from entering and affecting the transmission, and also preventing operators from accidentally touching and getting injured. In addition, the third servo motor moves synchronously with the crushing roller through the displacement plate, ensuring stable transmission connection during crushing. This solves the problem of easy disengagement between the motor and the crushing roller in the existing pretreatment device, and further enhances the efficiency and safety of equipment operation.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 , Figure 2 As shown in Figures 1 and 4, a crushing device for reinforcing masterbatch includes a pre-treatment crushing chamber 7. The equipment is fed into the pre-treatment crushing chamber 7 through a feeding port 9 fixedly installed on the top of the pre-treatment crushing chamber 7. The feeding port 9 is connected to the feed end of the pre-treatment crushing chamber 7. By increasing the area of ​​the feeding opening, the probability of spillage when the masterbatch is fed in is reduced, the feeding efficiency is improved, and raw material waste is avoided. At the same time, the controller 13 installed on the base 1 starts to function. The controller 13 is electrically connected to the first servo motor 3, the third servo motor 15, the second servo motor 11, and four cylinders 8, respectively. The coordinated operation of each component is realized through centralized circuit control, eliminating the need for manual operation of each device, simplifying the operation process, and improving the overall coordination and automation of the device.

[0026] like Figure 1 , Figure 2 , Figure 4 As shown, upon entering the pretreatment crushing stage, the second servo motor 11, fixedly installed on the side wall of the pretreatment crusher box 7, starts. Its output end rotates through the side wall of the pretreatment crusher box 7 and is fixedly connected to the center of the side wall of the crushing platform 10. The rotational driving force of the motor drives the crushing platform 10 to rotate within the side wall of the pretreatment crusher box 7, ensuring even distribution of the stiffening masterbatch on the platform and preventing local accumulation. Simultaneously, four cylinders 8 at the top of the pretreatment crusher box 7, located on the front and rear sides above the recess 21, start. The output end of the cylinders 8 is fixedly connected to the recess 21. 1. The top of the pre-treatment crusher box 7 has a recess 21 that is slidably connected to both sides of the inner wall of the pre-treatment crusher box 7. The linear extension and retraction of the cylinder pushes the recess 21 to slide up and down along the inner wall, thereby adjusting the distance between the crushing roller 14 and the crushing platform 10 that are movably connected between the recesses 21. The movable groove 20 opened on the side wall of the pre-treatment crusher box 7 cooperates with the lifting and lowering of the recesses 21 and the crushing roller 14 to provide lifting and lowering space for the recesses 21 and the crushing roller 14, avoiding interference with the side wall of the box during movement. The crushing distance can be adjusted according to the initial size of the masterbatch to ensure that the pre-treatment effect is suitable for the subsequent crushing process.

[0027] like Figures 1-5As shown, the crushing and grinding drive structure is activated. A rotating rod fixedly connected to one end of the crushing roller 14 passes through the side wall of the corresponding concave block 21. A third servo motor 15, fixedly connected to one end of the rotating rod, is slidably sleeved on the outer side wall of the rotating rod. The third servo motor 15 drives the rotating rod and the crushing roller 14 to rotate. At the same time, the displacement plate 19 moves synchronously with the rise and fall of the concave block 21, ensuring a stable transmission connection between the motor and the crushing roller 14, and realizing the stable rotation of the crushing roller 14. This performs preliminary crushing of the masterbatch on the crushing platform 10, reducing the volume of the masterbatch. The pre-treated masterbatch enters the crushing box 2 through the discharge port of the pre-treatment crushing box 7. The crushing rollers 6, which are rotatably connected to the two sides of the inner wall, start working. The first servo motor 3, which is fixedly connected to one end of any transmission rod 16, starts. The transmission gears 17, which are fixedly sleeved on the outer walls of the two transmission rods 16, mesh with each other. The first servo motor 3 drives one transmission rod 16 to rotate. Through the meshing transmission gear 17, the other transmission rod 16 is driven to rotate in the opposite direction, thereby causing the two crushing rollers 6 to rotate in the opposite direction to achieve the crushing action. The protective cover 4, which is fixedly installed on the top of the crusher box 2, is located above the two transmission gears 17. It isolates the gear transmission structure from the external environment, prevents foreign objects from entering and affecting the transmission or causing safety hazards, achieves efficient crushing of the masterbatch, and ensures the safe operation of the equipment.

[0028] like Figure 1 , Figure 5 As shown, the screen plate 18, which is fixedly installed on the inner wall of the crusher box 2 and below the two crushing rollers 6, plays a role in screening the crushed masterbatch through the screen holes. The masterbatch that meets the particle size requirements falls through the screen holes, while the masterbatch that does not meet the requirements remains on the screen plate 18 and can be crushed again in subsequent crushing processes to ensure the uniformity of the particle size of the crushed masterbatch and meet the processing requirements. The receiving box 12 is slidably connected to the slide 5 opened on the top of the base 1 and below the discharge end of the crusher box 2. The receiving box 12 can be easily pulled and moved through the slide 5 to receive the falling qualified masterbatch. After the receiving is completed, the operator can pull out the receiving box 12 along the slide 5 to unload the material, simplifying the receiving and unloading process, improving the work efficiency, and preventing the masterbatch from spilling during the collection process.

[0029] It should be noted that this type of stiffening masterbatch crushing device achieves automated crushing of masterbatch through the coordinated operation of multiple components. The controller 13 uniformly controls each execution component. At the start of operation, the operator feeds the stiffening masterbatch into the pretreatment crushing chamber 7 through the feed port 9. The feed port 9 reduces the probability of masterbatch spillage by widening the feed opening. At the same time, the controller 13 starts each power component to achieve centralized and automated control, eliminating the need for individual manual operation and improving overall coordination.

[0030] In the pretreatment stage, the second servo motor 11 drives the crushing platform 10 to rotate, so that the masterbatch is evenly distributed on the platform and avoids local accumulation that affects the crushing effect. At the same time, the four cylinders 8 push the concave block 21 to slide up and down along the inner side wall of the pretreatment crusher box 7, adjust the distance between the crushing roller 14 on the concave block 21 and the crushing platform 10 to match the initial size of the masterbatch. The movable groove 20 provides lifting space for the concave block 21 and the crushing roller 14 to prevent motion interference. Then, the third servo motor 15 drives the crushing roller 14 to rotate through the rotating rod. The displacement plate 19 moves synchronously with the concave block 21 to ensure stable transmission and perform preliminary crushing of the masterbatch to reduce its volume for subsequent crushing.

[0031] After initial crushing, the masterbatch is driven by the second servo motor 11 to rotate the crushing platform 10, causing the crushing platform 10 to tilt at a 30-degree angle. The masterbatch enters the crusher box 2. The first servo motor 3 drives a transmission rod 16 to rotate. Through two meshing transmission gears 17, the other transmission rod 16 rotates in the opposite direction, thereby driving the two crushing rollers 6 to run in the opposite direction, achieving efficient crushing of the masterbatch. The protective cover 4 isolates the transmission gears 17 from the external environment, avoiding interference from foreign objects and safety hazards.

[0032] The crushed masterbatch falls onto the screen plate 18, which filters out masterbatch with qualified particle size through the screen holes. Unqualified masterbatch is retained for further crushing to ensure uniform output. Qualified masterbatch finally falls into the receiving box 12 below. The receiving box 12 can be pulled and moved along the chute 5 for easy receiving and unloading, thus completing the entire crushing operation process.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
