Description

Technical Field

[0001] The utility model relates to the technical field of production of PPS modified plastic particles, in particular to a water-cooling cutting device for production of PPS modified plastic particles. Background Art

[0002] Polyphenylene sulfide, referred to as PPS, is a thermoplastic special engineering plastic with excellent comprehensive performance. During the cutting process of PPS modified plastic after extrusion molding, a water-cooled cutting device is required to cut the PPS modified plastic.

[0003] For example, a water-cooled cutting device for producing PPS modified plastic particles disclosed in a Chinese patent document (Announcement No.: CN221834733U) includes a base; an extruder body is fixedly connected to one side of the top of the base, a support frame is welded to the extruder body, a pneumatic cylinder is installed on the top of the support frame, the active end of the pneumatic cylinder is equipped with a pneumatic rod, the bottom end of the pneumatic rod is fixedly connected to a cutting knife, and a cold water tank is fixedly connected to the other side of the top of the base; when the extruded plastic is water-cooled and cut, the coordinated cooperation of the swing rod, the scraper and the spring can ensure that the scraper is always in close contact with the side wall of the cutting knife during the lifting and cutting process, so that the plastic particles adhered to the cutting knife can be scraped and cleaned, and the occurrence of adhesion at the cutting point can be prevented, thereby improving the cutting effect and ensuring the smoothness of the plastic strip cut, so that the PPS modified plastic cutting and molding effect is better.

[0004] However, the above solution still has the following shortcomings when implemented:

[0005] During cutting, the water pump is started to cool the cutting area through water flow. After the cooling is completed, the water flow mixed with small cutting fragments will enter the cold water tank. Therefore, when the water in the cold water tank is subsequently pumped out, the water pump will be blocked, and the small fragments cannot be effectively utilized and recycled, resulting in a waste of resources.

[0006] Therefore, we propose a water-cooling cutting device for producing PPS modified plastic particles. Utility Model Content

[0029] Example

[0030] like Figure 1-5 As shown, the utility model provides a technical solution: a water-cooled cutting device for producing PPS modified plastic particles, including a recovery box 1. The recovery box 1 is the core shell part of the entire device. It provides installation and working space for other components, and at the same time plays a role in protecting the internal structure and accommodating working media (such as water and plastic particles).

[0031] A partition net 4 is provided at the center of the recycling box 1. The partition net 4 has an important function in this device. Its principle is based on the difference in physical properties of different substances. For the water-cooled cutting environment in the production process of PPS modified plastic particles, the cut particles and water are mixed together. The mesh size of the partition net 4 is cleverly designed. It can block fine particles and allow the particles to remain above the partition net 4 according to the size of the particles, while water can flow smoothly through the mesh to the bottom. In this way, not only can the particles be recycled through the recycling component, but also the water and particles can be separated from each other, thereby realizing the filtration of the water. If the water contains a large amount of particles that directly enter the pipe and water pump, the particles may accumulate in the narrow part of the pipe or enter the inside of the water pump to destroy the normal operation of its impeller and other components, thereby avoiding blockage of the pipe and water pump.

[0032] A sliding groove 11 is provided on the back wall of the recovery box 1 , and a recovery component is installed on the back side of the recovery box 1 , and the recovery component is used to recover the particles on the separation net 4 .

[0033] The recovery component includes a screw rod 7, and a drive motor 8 is provided on the right side of the screw rod 7. The screw rod 7 is a key component that converts rotational motion into linear motion. Its principle is based on spiral transmission. The drive motor 8 provides power for the rotation of the screw rod 7. When the drive motor 8 rotates, the output shaft of the motor drives the screw rod 7 to rotate.

[0034] A connector 9 is installed on the screw rod 7, and a scraper 10 is provided at the connection of the connector 9. The connector 9 passes through the sliding groove 11. The scraper 10 is installed inside the recycling box 1 and is located on the top of the partition net 4. The drive motor 8 can drive the screw rod 7 to rotate, thereby driving the connector 9 to perform linear motion. When the screw rod 7 rotates, the connector 9 will perform linear motion along the axial direction of the screw rod 7 due to the spiral fit with the screw rod 7. The connector 9 drives the scraper 10 to move together, and the scraper 10 can slide on the upper surface of the partition net 4, scraping the plastic particles on the partition net 4 to the designated collection position, thereby realizing the recovery of the particles.

[0035] The recovery component also includes a fixed seat 5, which has an installation cavity 6 inside. The screw rod 7 is installed inside the installation cavity 6, and the left side of the screw rod 7 is connected to the side wall of the fixed seat 5 through a bearing. The fixed seat 5 provides a stable installation support for the screw rod 7, and the installation cavity 6 provides a suitable space for the rotation of the screw rod 7. The bearing reduces the friction between the screw rod 7 and the fixed seat 5 when it rotates, ensuring that the screw rod 7 can rotate smoothly.

[0036] A water storage seat 13 is provided below the partition net 4, and a recovery pipe 14 is installed at the bottom of the water storage seat 13. The water storage seat 13 is used to collect water filtered through the partition net 4, and the recovery pipe 14 is a channel for draining the water so that the water can be recycled or subjected to other treatments.

[0037] A material guide trough 2 is installed on the top of the recycling box 1. A number of flow holes 3 are opened on the top of the material guide trough 2. The material guide trough 2 is used to receive a mixture of plastic particles and water transmitted from the water-cooled cutting equipment. The design of the flow holes 3 allows water and unqualified particles or impurities cut off to enter the recycling box 1 evenly, which is beneficial to subsequent separation and recycling work.

[0038] A water pump is installed at the connection of the recovery pipe 14 to provide power for water recovery. The water pump rotates its own impeller to form a negative pressure in the pipe, thereby pumping out the water in the water storage seat 13 and allowing the water to flow along the recovery pipe 14.

[0039] A sealing door 12 is installed on the left side wall of the recovery box 1. The sealing door 12 and the recovery component cooperate with each other. The function of the sealing door 12 is to facilitate the maintenance, cleaning and removal of the recycled materials inside the recovery box 1. When it is necessary to inspect the recovery component (such as the scraper 10) or clean the residual particles inside the recovery box 1, the sealing door 12 can be opened for operation.

[0040] A fixed base frame 15 is installed at the bottom of the recycling box 1, and the fixed base frame 15 is welded to the recycling box 1. The fixed base frame 15 provides stable support for the entire recycling box 1 to ensure that the device will not shake or tip over during operation. The welding connection method ensures the connection strength between the fixed base frame 15 and the recycling box 1.

[0041] During operation, a mixture containing PPS modified plastic particles and water enters the recovery box 1 from the guide trough 2, and the mixture is evenly sprinkled on the partition net 4 through the flow hole 3 of the guide trough 2. The water flows through the partition net 4 to the water storage seat 13, and the particles remain on the partition net 4. Then the drive motor 8 is started, and the drive motor 8 drives the screw rod 7 to rotate. The connecting piece 9 on the screw rod 7 carries the scraper 10 to move linearly along the sliding groove 11. The scraper 10 scrapes the particles on the partition net 4 to the designated position for collection. The water in the water storage seat 13 is pumped out through the recovery pipe 14 under the action of the water pump and can be recycled or otherwise processed.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
