Description

Technical Field

[0001] The utility model belongs to the technical field of plastic water pipes, and particularly relates to a mixer for granular masterbatch used in the production of plastic water pipes. Background Technique

[0002] In the production of plastic water pipes, especially PVC (polyvinyl chloride) plastic water pipes, the mixing of raw materials is a key step. Plastic particles are the basic raw materials for the production of plastic pipes, and they can be general plastics, engineering plastics, special plastics, etc. After granulation and mixing, these particles need to go through a packaging process for subsequent processing and use. During the production process, different types of raw materials need to be stored separately and mixed in a specific proportion and method at the appropriate time to ensure the quality of the final product. However, some existing mixers are usually integrated, without moving wheels at the bottom for convenient movement of the device. A mixer without moving wheels will be more laborious when it needs to be moved, and more manpower or handling equipment may be required, which will increase production costs and time. At the same time, some mixers only have a small feeding port. The small feeding port will limit the speed of adding raw materials, and it is not convenient to observe the working conditions in the mixing chamber. It is also not convenient to clean the device. The raw materials remaining inside the mixer may solidify or adhere to the equipment, resulting in blockage of the discharge port or difficulty in cleaning. This will increase the maintenance cost and downtime of the equipment.

[0003] The existing authorized publication number is CN 218905911 U, which discloses a mixer for granular masterbatch used in the production of plastic water pipes, including a mixer box body. One side of the mixer box body is fixedly connected with a driving motor. The output shaft of the driving motor is fixedly connected with a driving shaft through a coupling. The outer wall of the driving shaft is fixedly connected with stirring blades. One side of the mixer box body is provided with a discharge port. The bottom wall of the mixer box body is fixedly connected with a guide plate. The top wall of the mixer box body is fixedly connected with a storage tank. The bottom of the storage tank is fixedly connected with a feeding pipe, and an electromagnetic valve is fixedly connected to the outer wall of the feeding pipe. This mixer for granular raw materials used in the production of PVC plastic water pipes realizes the function of classifying and storing different types of raw materials, thus facilitating the control of different raw materials to enter the mixing process at the appropriate time during subsequent raw material mixing, and improving the convenience during raw material mixing.

[0004] However, the bottom of the above device is a smooth plane, and there are no moving wheels provided on the bottom for moving the device. During the production process, it may be necessary to move the mixer to different positions according to different production requirements. The lack of moving wheels will make this process complicated, thus affecting the overall production efficiency. At the same time, the discharge port of the device is arranged on the side wall at the lowest side of the bottom of the box body, which may cause some raw materials to remain in the corners or at the bottom of the mixer and be difficult to be completely discharged. This will result in waste of raw materials and reduction of production efficiency. The raw materials remaining inside the mixer may solidify or adhere to the equipment, causing blockage of the discharge port or difficulty in cleaning. This will increase the maintenance cost and downtime of the equipment. Therefore, it is necessary to propose a mixer for granular masterbatch used in the production of plastic water pipes to solve the above problems. Summary of the Invention

Detailed implementation manners

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 . A mixer for granular masterbatch used in the production of plastic water pipes includes: a box 6 for placing the masterbatch, a support frame 5 fixedly arranged on the side wall of the box 6, a stirring mechanism 8 rotatably connected inside the box 6 for stirring the masterbatch inside the box 6, a drive motor 4 for stirring the stirring mechanism 8 placed on the top of the support frame 5, a bottom plate 1 fixedly arranged at the bottom of the support frame 5 for supporting the whole device, a box lid 7 rotatably connected above the box 6, a guide plate 12 arranged below the stirring mechanism 8, a baffle plate 11 inserted in the front side of the box 6 for controlling the falling of the stirred masterbatch, a control mechanism 9 for controlling the mixed masterbatch opened at the bottom of the box 6, moving wheels 2 arranged at the bottom of the bottom plate 1 for moving the whole device, and a support mechanism arranged on the side of the bottom plate 1 for providing additional support. The support mechanism includes a fixed sleeve 4, wherein the connecting fixed sleeve 4 is fixed on the side of the bottom plate 1; the stirring mechanism 8 includes a rotating shaft 82, wherein the rotating shaft 82 is fixed on both sides inside the box 6 and is rotatably connected to the drive motor 10 at one end.

[0027] Four moving wheels 2 are fixed around the bottom of the bottom plate 1. The moving wheels can conveniently move the mixer to different positions, improving the flexibility and adaptability of the equipment. When it is necessary to switch production lines or perform equipment maintenance, the moving wheels can help quickly move the mixer to the corresponding position, reducing the downtime and improving the production efficiency.

[0028] The support mechanism includes support rods 3 and fixed sleeves 4. Threads are evenly distributed on the outer surface of the support rods 3. The support rods 3 are threadedly inserted into the fixed sleeves 4, and threaded grooves matching the support rods 3 are opened inside the fixed sleeves 4. By rotating the support rods 3 to make their bottoms contact the ground, additional stability and strength can be provided. At the same time, it helps to reduce the pressure of the whole device on the moving wheels 2 and improve the service life of the device.

[0029] Support frames 5 are fixed on both sides of the box 6, and the support frames 5 are in an inverted L-shaped structure. The drive motor 10 is fixed by abutting on the top of the support frame 5. The support frame 5 provides additional support force for the drive motor 10 and reduces the pressure on the connection part between the drive motor 10 and the rotating shaft 82.

[0030] The material guiding plate 12 is designed with a wider upper part and a narrower lower part. Above the outlet of the material guiding plate 12, a baffle plate 11 is placed to control the masterbatch to be stirred above the material guiding plate 12. By clamping a baffle plate on the material guiding plate of the box body, a stirring bin space is formed above the material guiding plate of the box body. The stirring mechanism 8 includes blades 81, a rotating shaft 82 and fixed columns 83. The blades 81 of the stirring mechanism 8 are strip-shaped structures. The blades 81 are disc-shaped structures with sharp edges. They are installed on the rotating shaft 82 and contact the masterbatch through rotation. The fixed columns 83 are fixed on the blades 81 and the rotating shaft 82. Since the strip-shaped blades 81 are affected in firmness, the fixed columns 83 are needed to provide additional fixation. The design of the baffle plate can concentrate the stirring mechanism to mix and stir the raw materials, improving the stirring efficiency and speed, ensuring that the raw materials are fully mixed and evenly stirred, thus guaranteeing the quality stability of the final product. At the same time, pulling out the baffle plate enables the stirred masterbatch to enter the lower box body 6 from the discharge port of the material guiding plate 12 for storage, reducing the waiting time for the next batch of masterbatch to be stirred.

[0031] The bottom of the inner cavity of the box body 6 is set as a quadrangular pyramid structure with a wider upper part and a narrower lower part. The inner cavity of the box body 6 is connected through the control mechanism 9 arranged at the bottom. The control mechanism 9 includes a discharge pipe 91, a retaining piece 92 and a fixed pipe 93. The discharge pipe 91 and the fixed pipe 93 are connected by nuts, and a groove for the retaining piece 92 to be inserted and move is opened at the connection of the two. By using the baffle plate 11, a space is formed at the lower part of the box body 6 to temporarily store the already stirred masterbatch, and a control mechanism 9 is arranged at its bottom to control the discharge of the masterbatch. The control mechanism 9 can accurately control the discharge amount by inserting and removing the retaining piece 92 inserted between the discharge pipe 91 and the fixed pipe 93 as needed, which helps to avoid waste or overproduction, thus improving the resource utilization rate and reducing costs.

[0032] The working principle of a mixer for granular masterbatch used in the production of plastic water pipes provided by the present utility model is as follows:

[0033] First, ensure that the mixer is on a flat ground and the moving wheels 2 are not blocked. Check whether the equipment is in good condition, especially whether the moving wheels 2 can rotate normally. Push it to a suitable position and lock the moving wheels 2, and then support the ground by rotating the support rod 3 threadedly connected in the fixed sleeve 4.

[0034] Insert the baffle plate 11 into the box body 6, open the box cover 7 of the mixer, and add the granular raw materials to be mixed into the inside of the box body 6. During the feeding process, attention should be paid to avoiding the raw materials from spilling or piling up on the moving wheels 2. Start the driving motor 10 to drive the stirring mechanism 8 to rotate, and set the stirring speed and time as needed. During the stirring process, closely observe the operation of the equipment. If there is any abnormality, stop the machine immediately for inspection.

[0035] After the stirring is completed, the baffle 11 is withdrawn, and the mixed raw materials are discharged to the bottom of the box body 6 through the material guide plate 12. If necessary, the baffle piece 92 of the control mechanism 9 is operated and taken out. If it is necessary to move the mixer to other positions, it should be ensured that the equipment has stopped running and cooled down first. Then, the support rod 3 threadedly connected and rotated in the fixed sleeve 4 is moved away from the ground, and the moving wheels 2 are used for moving. During the moving process, attention should be paid to avoiding collision or friction to prevent damage to the equipment or the ground.

[0036] After use, the residual raw materials inside and outside the box body 6 should be cleaned in time to keep the equipment clean. At the same time, the moving wheels 2 should be regularly inspected and maintained to ensure their normal operation.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, or directly or indirectly applied.
