Description

Technical Field

[0001] The utility model relates to the technical field of plastic production equipment, in particular to a reverse-folding wire wheel plastic cooling water tank. Background Art

[0002] In the production of engineering plastic modification, the material strips extruded from the extruder head after high-temperature melting in the plastic extruder need to be cooled before entering the pelletizing system for pelletizing, and this cooling process is the process of the material strips passing through the water tank. The cooling process of the material strips from the extruder to the water tank will release a lot of heat, and the temperature of the water tank will continue to rise, especially the water temperature at the water inlet of the material strips, that is, the water tank is close to the extruder head of the plastic extruder.

[0003] The general extruder water sink on the market is shown in the patent document with patent number CN202121447553.3 and name "A plastic extruder water sink", which includes a water tank and guide rollers. A number of guide rollers are provided and rotatably connected to the inside of the water tank. The water tank is filled with coolant, and the liquid level of the coolant is higher than the guide rollers. The water tank is connected with an inlet pipe and an outlet pipe, a water pump is connected in series on the inlet pipe, and an electromagnetic valve is connected in series on the outlet pipe. The inlet pipe and the outlet pipe are connected to a chiller at one end away from the water tank. The chiller is used to continuously circulate and cool the coolant, so as to achieve the effect of maintaining the cooling effect of the water sink on the high-temperature plastic strips for a long time.

[0004] However, since the high-temperature plastic strips output by the extruder need to be immersed in the water tank for a period of time before the surface can be cooled down, the water tank must occupy a long distance, especially when granulating soft plastics such as PP and PE. To provide sufficient immersion time for the plastic strips, the water tank requires a high space in the production workshop and cannot be placed in a relatively small workshop. In addition, although the water tanks on the market are equipped with equipment such as chillers to improve the cooling effect of the plastic strips in the water tank, if the high-temperature plastic strips are directly immersed in cold water with a large temperature difference, it is easy to cause cracks and other adverse reactions. Therefore, it is impossible to improve the cooling effect of the plastic strips simply by using cooling water.

[0005] In view of this, it is necessary to develop a cooling water tank that has a good cooling effect on high-temperature plastic strips and occupies a small volume. Utility Model Content

[0006] In order to solve the problem that the plastic strip cooling water tank configured at the rear of the general plastic production extruder occupies a large space, has an unstable cooling effect on the high-temperature plastic strips, and cannot guarantee the subsequent plastic strip raw material pelletizing production quality, a reverse-folding wire wheel plastic cooling water tank is provided.

[0007] The inverse folded wire wheel plastic cooling water trough comprises a water trough, in which a cold water layer is poured, in which a plurality of underwater wire wheels are arranged and installed, and reversing wire wheels are arranged at the front and rear ends of the cold water layer, wherein the height of the reversing wire wheel is greater than that of the underwater wire wheel, and the underwater wire wheels are arranged between the two reversing wire wheels, and a plurality of drain wire wheels are arranged above the water trough.

[0008] Furthermore, the surfaces of the underwater wire wheel, the reversing wire wheel and the drain wire wheel are all arranged with a plurality of guide grooves.

[0009] Furthermore, the underwater wire wheel, the reversing wire wheel and the drain wire wheel are all installed on a wire wheel bracket, and the wire wheel bracket is detachably installed in the water tank.

[0010] Furthermore, an inverted L-shaped holder is symmetrically arranged on the left and right sides of the wire wheel bracket, and the inverted L-shaped holder is movably sleeved on the top of the side wall of the water tank.

[0011] Furthermore, one side of the reel bracket is connected to one end of a wheel axle via an upper and lower hinge, and a wheel axle holder is provided on the opposite side of the reel bracket corresponding to the upper and lower hinges, and the underwater reel, reversing reel and drain reel are all individually rotatably sleeved on a wheel axle.

[0012] Furthermore, a lower wire pressing wheel is arranged at the inner front end of the water tank corresponding to the upstream of the underwater wire wheel.

[0013] Furthermore, the water tank is connected to a water inlet and a water outlet corresponding to the cold water layer, and the water inlet and the water outlet are both connected to a chiller.

[0014] The advantages of the utility model are:

[0015] 1. It can provide sufficient water-immersed heat dissipation path for the high-temperature plastic strips output by the plastic production extruder in a limited space to ensure that the plastic strips are fully cooled.

[0016] 2. After the plastic strips are cooled, they can be drained to avoid excessive humidity in the plastic strips that affects product quality.

[0017] 3. The space occupied by equipment is significantly reduced, which helps to reduce the site cost of the production workshop and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 3 As shown, the present embodiment provides an inverted wire wheel plastic cooling water trough, comprising a water trough 1, wherein the water trough 1 is filled with a cold water layer 101, wherein a plurality of underwater wire wheels 2 are arranged and installed in the cold water layer 101, and a reversing wire wheel 3 is arranged at the front end and the rear end inside the cold water layer 101, wherein the height of the reversing wire wheel 3 is greater than that of the underwater wire wheel 2, and the underwater wire wheels 2 are arranged between the two reversing wire wheels 3, and a plurality of drain wire wheels 4 are also arranged above the water trough 1.

[0029] In actual use, the underwater wire wheel 2 presses the plastic strip 10 downwards and is used to press the plastic strip 10 into the cold water layer 101. The reversing wire wheel 3 is used to guide the plastic strip 10 to reverse, so that the plastic strip 10 can be folded back and forth in the cold water layer 101 to increase the water cooling time and ensure the cooling effect. The drain wire wheel 4 is used to allow the plastic strip 10 to continue to be transported on the top of the drain wire wheel 4 after the plastic strip 10 leaves the cold water layer 101, so that the water on the surface of the plastic strip 10 falls into the water tank 1 for draining, so as to avoid excessive water content of the plastic strip 10 affecting product quality.

[0030] The surfaces of the underwater line wheel 2, the reversing line wheel 3 and the drain line wheel 4 are arranged with a plurality of guide grooves 5. The guide grooves 5 can effectively constrain the traveling direction of the plastic strip 10, avoid its deviation and winding, and ensure smooth transportation.

[0031] The underwater wire wheel 2, the reversing wire wheel 3 and the drain wire wheel 4 are all mounted on the wire wheel bracket 6, and the wire wheel bracket 6 is detachably mounted in the water tank 1. Each wire wheel is installed with the wire wheel bracket 6, which is convenient for management and convenient for staff to configure the positions of various wire wheels as needed.

[0032] The left and right sides of the wire wheel bracket 6 are symmetrically provided with an inverted L-shaped holder 7, and the inverted L-shaped holder 7 is movably sleeved on the top of the side wall of the water tank 1. The wire wheel bracket 6 can be adjusted and assembled and disassembled at any time, which is convenient for the staff to adjust the spatial arrangement and number of wire wheels at any time according to production needs.

[0033] One side of the reel bracket 6 is connected to one end of the axle 8 via an upper and lower hinge 801, and an axle holder 802 is provided on the opposite side of the reel bracket 6 corresponding to the upper and lower hinges 801, and the underwater reel 2, the reversing reel 3 and the drain reel 4 are all individually rotatably sleeved in an axle 8. The upper and lower opening and closing design of the axle 8 facilitates the removal of the reel for cleaning and maintenance, effectively improving the work efficiency of equipment maintenance.

[0034] A lower pressing wheel 9 is provided at the inner front end of the water tank 1 corresponding to the upstream of the underwater wire wheel 2. The lower pressing wheel 9 can provide guidance for the high-temperature plastic strip 10 output by the extruder, so that it can quickly sink into the depth of the cold water layer 101, which helps to extend the movement stroke of the plastic strip 10 in the water tank 1.

[0035] The water tank 1 is connected to a water inlet and a water outlet corresponding to the cold water layer 101, and the water inlet and the water outlet are connected to a chiller 102. The chiller 102 can timely cool the cold water layer 101 which has heated up due to absorbing the heat of the high-temperature plastic strip 10, ensuring that the water tank 1 provides a continuous and stable cooling effect.

[0036] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
