Description

Technical Field

[0001] The utility model belongs to the technical field of plastic granulation equipment and relates to a drying mechanism on a cooling tank. Background Art

[0002] In the process of plastic granulation, the raw materials need to be stirred evenly, and then introduced into the extruder for heating and extrusion to form thin and long plastic strips. In order to make the extruded plastic strips cool and solidify quickly, they are generally passed through a cooling water tank and quickly cooled under the action of cold water, and then the thin and long plastic strips are pulled into the cutting machine and cut into granules. After the plastic strips are passed through the water, there is moisture on their surface, which needs to be dried before they are allowed to enter the granulator to avoid the moisture affecting the quality of the product. Therefore, a drying mechanism needs to be installed at the end of the cooling tank. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and provide a drying mechanism on a cooling tank, so that the plastic strips can be dried after being passed through water, thereby ensuring the quality of the product.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a drying mechanism on a cooling trough, the cooling trough comprises a frame, a hot air blower, a water-cooling trough and a drain trough, the drain trough being fixed at the rear end of the water-cooling trough; it is characterized in that a wiping mechanism and an air-drying mechanism are fixed at the top of the drain trough, and the wiping mechanism is located at the front end of the air-drying mechanism; the wiping mechanism comprises a wiping box with an open top, a mesh plate is provided at the bottom of the wiping box, a avoidance groove is provided on one side wall of the wiping box, and a sponge is provided in the wiping box; the air-drying mechanism comprises a bottom box fixed at the top of the drain trough 3, a plurality of guide grooves are provided on the upper surface of the bottom box; a bellows is hinged on one side wall of the bottom box, a plurality of air outlet holes corresponding to each guide groove are provided at the bottom of the bellows, and a soft sealing layer is provided at the bottom of the bellows; an air inlet pipe is provided at the top of the bellows, and a hose is provided between the air inlet pipe and the hot air blower for conduction connection; a tightening lock is also provided between the bellows and the bottom box.

[0005] The utility model has the advantages:

[0006] 1. In this drying mechanism, the air drying mechanism changes the direction of hot air through the air duct, increases the wind receiving area of ​​each plastic pull strip, and thus improves the air drying effect without increasing energy consumption, making it more energy-saving.

[0007] 2. This drying mechanism dries the plastic strips by wiping first and then air drying, which further reduces the drying energy consumption and can remove impurities during the wiping process to ensure product quality.

[0008] 3. In the drying mechanism, each air duct is composed of the guide groove 52 and the bottom of the bellows, so the staff does not need to insert each pull rod into each air duct one by one. It is only necessary to slightly adjust the position of each pull rod after the pull rod moves stably so that it is located in each guide groove respectively, and then close the bellows and the bottom box. This greatly reduces the workload of workers and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 As shown, a drying mechanism on a cooling tank, the cooling tank includes a frame 1, a hot air blower, a water cooling tank 2 and a drain tank 3, the drain tank 3 is fixed to the rear end of the water cooling tank 2; a wiping mechanism 4 and an air drying mechanism 5 are fixed to the top of the drain tank 3, and the wiping mechanism 4 is located at the front end of the air drying mechanism 5; Figure 2 As shown, the wiping mechanism 4 includes a wiping box 41 with an open top, a mesh plate 42 is provided at the bottom of the wiping box 41, a side wall of the wiping box 41 is provided with an avoidance groove 43, and a sponge 44 is provided in the wiping box 41; Figure 3 The air-drying mechanism 5 includes a bottom box 51 fixed on the top of the drain trough, and a plurality of guide grooves 52 are provided on the upper surface of the bottom box 51; a bellows 53 is hinged on one side wall of the bottom box 51, and a plurality of air outlet holes 54 corresponding to the guide grooves 52 are opened at the bottom of the bellows 53, and a soft sealing layer 55 is provided at the bottom of the bellows 53; an air inlet pipe 56 is provided at the top of the bellows 53, and a hose is provided between the air inlet pipe 56 and the hot air blower for conduction connection; a tension lock 57 is also provided between the bellows 53 and the bottom box 51.

[0015] Working principle: The plastic strip extruded by the extruder is cooled in the water cooling tank 2 and then pulled into the drain tank 3, and then passes through the wiping mechanism 4 and the air drying mechanism 5. A side wall at the front end of the wiping mechanism 4 is provided with an avoidance groove 43, which allows the plastic strip to contact the sponge 44 as much as possible, so that the moisture and impurities adhering to it are automatically wiped away during the movement of the plastic strip; and the sponge 44 continuously wipes the plastic strip, and the moisture contained in it becomes more and more, and leaks out through the mesh plate 42 at the bottom of the wiping box 41, thereby ensuring its wiping effect. The top of the bottom box 51 of the air drying mechanism 5 has a plurality of guide grooves 52, so when the hinged bellows 53 and the bottom box 51 are tightly closed, each guide groove 52 will be spliced ​​with the bottom of the bellows 53 to form an air duct; and the hot air provided by the hot air blower will be given to each air outlet 54 through the bellows 53, and then blown out from both ends of each air duct after being redirected by each air duct.

[0016] Compared with the prior art, the present air-drying mechanism 5 changes the direction of hot air through the air duct, increases the wind receiving area of ​​each plastic pull rod, and thus improves the air-drying effect without increasing energy consumption, making it more energy-efficient. Secondly, the present drying mechanism dries the plastic pull rod by wiping first and then air-drying, which further reduces the drying energy consumption, and can remove impurities during the wiping process to ensure the quality of the product. Thirdly, in the present drying mechanism, each air duct is composed of the guide grooves 52 on the bottom box 51 and the bottom of the bellows 53, so there is no need for the staff to insert each pull rod into each air duct one by one. It is only necessary to slightly adjust the position of each pull rod after the pull rod moves stably, so that it is respectively located in each guide groove 52, and then close the bellows 53 and the bottom box 51. This greatly reduces the workload of the workers and improves production efficiency.

[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
