Description

Technical Field

[0001] This utility model relates to the field of underwater pelletizer technology, specifically to a hydraulic control console for an underwater pelletizer. Background Technology

[0002] Underwater pelletizers, as the name suggests, are machines that process materials in water. They are characterized by high efficiency, high stability, and high safety, and have been favored by many users. Underwater pelletizers are a new type of polymer semi-finished product processing machine. They are named as such because the cutting process takes place in water. Currently, in China, the hydraulic control consoles of existing underwater pelletizers used for processing polyester polymer chips and pellets have many shortcomings.

[0003] An underwater pelletizer, as described in application number CN202221798574.4, belongs to the field of pelletizers. It includes a pelletizing box and an extrusion template mounted on one side of the pelletizing box. Support rods are fixedly installed at the four corners inside the pelletizing box, and the extrusion template is slidably sleeved onto the support rods at the four corners. A screw is rotatably installed on the top of the inner wall of the pelletizing box, and the top of the extrusion template is threaded onto the screw. A motor is fixedly installed on the side of the pelletizing box away from the extrusion template, and a cutter shaft is fixedly installed at the output end of the motor. A blade is fixedly installed at the end of the cutter shaft near the extrusion template. A discharge pipe is fixedly connected to the bottom of the pelletizing box, and a collection box is fixedly connected to the bottom of the discharge pipe. A filter screen is fixedly installed in the middle of the collection box. The support rods and screw facilitate the replacement of the extrusion template when producing pellets of different specifications, eliminating the need to replace the entire underwater pelletizer and reducing operating costs. However, the cooling effect of the hydraulic control console is not good. Excessive oil temperature will reduce the performance of components, and impurities are easy to clog the pipeline if not cleaned in time. The equipment maintenance is also more complicated.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a hydraulic control console for an underwater pelletizer. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic control console for an underwater pelletizer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic control console for an underwater pelletizer, comprising a fixed base and a cooling enhancement mechanism, characterized in that the cooling enhancement mechanism is fixedly connected to one side of the fixed base, and the cooling enhancement mechanism includes a guide fan fixedly connected to one side of the fixed base, and an airflow adjustment plate is rotatably connected to the top of the guide fan, cooling fins are provided on the top of the guide fan, and a power interface is provided on one side of the guide fan.

[0007] Preferably, a hydraulic pump unit is fixedly connected to the top of the fixed base, and a water inlet protection mechanism is fixedly connected to the top of the hydraulic pump unit.

[0008] Preferably, the water inlet protection mechanism includes a bypass pipe interface fixedly connected to the top of the hydraulic pump unit, and a filter screen cylinder is provided inside the bypass pipe interface, with a drain valve port opened on one side of the filter screen cylinder.

[0009] Preferably, a mold head assembly is fixedly connected to one side of the hydraulic pump unit, and the inner surface of the mold head assembly is provided with a mold outlet.

[0010] Preferably, a module interface is fixedly connected to one side of the hydraulic pump unit, and a slide rail is fixedly connected to the bottom of the fixed base.

[0011] Preferably, a slide block is slidably connected to the inner surface of the slide rail, and a lifting seat is slidably connected to the top of the slide block.

[0012] Preferably, a shock-absorbing and reinforcing seat is fixedly connected to the top of the lifting seat, and a pelletizing motor is provided on the inner surface of the shock-absorbing and reinforcing seat. A pelletizing knife is fixedly connected to the output end of the pelletizing motor, and an operation box is provided on one side of the slide.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model constructs an efficient heat dissipation system through the setting of a cooling enhancement mechanism, which quickly absorbs the large amount of heat generated by the die head assembly during pelletizing. When the temperature of the die head assembly rises, the opening and closing degree of the air volume regulating plate is increased to accelerate the air flow speed and enhance the heat dissipation effect. When the temperature drops, the air volume is appropriately reduced to avoid over-cooling. Through the close cooperation of the three, the cooling enhancement mechanism can accurately control the temperature of the die head assembly, effectively prevent the performance degradation of hydraulic components caused by high temperature, ensure the stability and reliability of equipment operation, and significantly improve production efficiency and pelletizing quality.

[0015] 2. This utility model, through the setting of a protective water inlet mechanism, provides a solid guarantee for the smooth operation of the bypass pipe interface. It can accurately intercept impurities of various sizes such as mud, rust, and plastic fragments in the water. When water flows through, these impurities are blocked and cannot enter the pipeline. The bypass pipe interface is always in a state free from impurity interference, and the water can flow smoothly without the flow rate decreasing or the pipeline becoming blocked due to the accumulation of impurities. This effectively maintains the stable operation of the entire hydraulic system, significantly reduces equipment failures caused by impurity blockage, extends the service life of the equipment, and ensures the efficient operation of the underwater pelletizer.

The cooling fins 203 are closely arranged on the outside of the die assembly 5 to increase the heat dissipation area. The guide fan 201 is located directly below the cooling fins 203. The airflow regulating plate 202 adjusts the airflow of the guide fan 201 and controls the cooling intensity according to the temperature of the die assembly 5.

[0023] like Figure 1As shown, a hydraulic pump assembly 3 is fixedly connected to the top of the fixed base 1, and a protective water inlet mechanism 4 is fixedly connected to the top of the hydraulic pump assembly 3. The protective water inlet mechanism 4 includes a bypass pipe interface 401 fixedly connected to the top of the hydraulic pump assembly 3, and a filter screen 402 is provided inside the bypass pipe interface 401. A drain valve port 403 is provided on one side of the filter screen 402. The filter screen 402 is installed at the inlet of the bypass pipe interface 401 to intercept impurities. By periodically opening the drain valve port 403, impurities in the filter screen 402 can be discharged to ensure smooth flow of liquid inside the bypass pipe interface 401.

[0024] Furthermore, a die head assembly 5 is fixedly connected to one side of the hydraulic pump unit 3, and a die outlet 6 is provided on the inner surface of the die head assembly 5. A module interface 7 is fixedly connected to one side of the hydraulic pump unit 3, and a slide rail 8 is fixedly connected to the bottom of the fixed base 1. A material outlet is provided on one side of the inner wall of the die head assembly 5. The module interface 7 is connected to an automatic feeding mechanism, and the die outlet 6 discharges material quantitatively, accurately matching the feeding and pelletizing speeds to improve production efficiency and pelletizing quality.

[0025] Furthermore, a slide seat 9 is slidably connected to the inner surface of the slide rail 8, and a lifting seat 10 is slidably connected to the top of the slide seat 9. A shock-absorbing and reinforcing seat 11 is fixedly connected to the top of the lifting seat 10, and a pelletizing motor 12 is provided on the inner surface of the shock-absorbing and reinforcing seat 11.
