Description

Technical Field

[0001] This utility model belongs to the field of PU foam wheel production equipment, and specifically relates to a cooling device for manufacturing PU foam wheels. Background Technology

[0002] Currently, in the production process of PU foaming wheels, the cooling process after foaming directly affects product quality and production efficiency. Existing technologies have the following drawbacks: when using existing foaming wheel cooling devices, it is mostly necessary to cool each foaming wheel individually for a long time after production. However, this method is not conducive to mass production because the cooling time for a single foaming wheel is too long.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a cooling device for manufacturing PU foam wheels, which solves the problem that existing foam wheel cooling devices often require long-term, time-limited cooling of each foam wheel after production. However, this method is not conducive to mass production because the cooling time for a single foam wheel is too long. Utility Model Content

[0004] This utility model proposes a cooling device for manufacturing PU foam wheels, which solves the problem that existing foam wheel cooling devices often require cooling each foam wheel individually for a long time after production, but this method is not conducive to mass production because the cooling time for a single foam wheel is too long.

[0005] The technical solution of this utility model is implemented as follows: A cooling device for manufacturing PU foam wheels includes: a housing mechanism, the main body of which is a one-way open structure at the front end, and a partition assembly is fixedly connected inside the front opening of the housing mechanism. The partition assembly has two through holes inside, and a filter assembly is fixedly connected inside each through hole. There are four filter assemblies in total, with each pair of longitudinally adjacent filter assemblies forming a group. Two groups of filter assemblies are fixedly connected in a linear array inside the left and right through holes of the partition assembly. A servo motor B is installed at the bottom of each group of filter assemblies, and a fan blade assembly is installed on the top output shaft of the servo motor B.

[0006] In a preferred embodiment, the servo motor B and the fan blade assembly together form a drive and heat dissipation structure, and a door assembly is hinged to the bottom of the front opening of the housing mechanism, and a hatch assembly is also hinged to the upper side of the front opening of the housing mechanism.

[0007] In a preferred embodiment, the interior of the door assembly has a rectangular array of heat dissipation slots, which together with the door assembly form an air intake structure.

[0008] In a preferred embodiment, the hatch assembly has a through slot inside, into which a glass window is embedded, and handle assemblies are fixedly connected to the front end faces of both the hatch assembly and the box door assembly.

[0009] In a preferred embodiment, a through groove is provided on the inner side of the housing mechanism, and a support mechanism is fixedly connected inside the through groove. There are two support mechanisms, which are fixedly connected to the front and rear sides of the housing mechanism in opposite directions.

[0010] In a preferred embodiment, guide roller assemblies are rotatably connected to the inner sides of the two support mechanisms. There are two guide roller assemblies in total, and the two guide roller assemblies are rotatably connected to the inner sides of the two support mechanisms in a linear array.

[0011] In a preferred embodiment, a servo motor A is mounted on the front end face of the support mechanism located on the front side. The servo motor A is connected to the guide roller assembly located on the left side. A conveying assembly for conveying the foaming wheel is also mounted on the outer side of the two guide roller assemblies.

[0012] After using the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the conveying component operates continuously under the drive of servo motor A, allowing the foaming wheel to pass through the cooling chamber without stopping, breaking through the limitations of traditional limited cooling. The cooling time per cycle is shortened by about %. At the same time, the forced convection heat dissipation formed by servo motor B and fan blade assembly, combined with the circulating filtration of filter assembly, maintains a stable low-temperature airflow environment in the cooling chamber. Compared with natural cooling, the efficiency is significantly improved, the overall production cycle is significantly shortened, and the needs of mass production are met.

[0014] 2. In this utility model, the box door assembly and hatch assembly at the front end of the shell mechanism can be opened independently through the handle assembly, which facilitates the operator to quickly inspect the conveying system or clean the filter assembly, significantly reducing maintenance time. The rectangular array design of the heat dissipation slot increases the air intake volume. Combined with the through hole layout of the partition assembly, the airflow evenly covers the surface of the foaming wheel, avoiding the problem of uneven cooling caused by the traditional single air inlet. The product cooling consistency is improved, effectively reducing defects such as bubbles and deformation caused by local overheating, and significantly improving the yield rate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, a cooling device for manufacturing PU foam wheels includes: a housing mechanism 1, the main body of the housing mechanism 1 having a one-way opening at the front end, and a partition assembly 101 fixedly connected inside the front opening of the housing mechanism 1.

[0025] The partition assembly 101 has two through holes inside, and filter screen assemblies 3 are fixedly connected inside the through holes. There are four filter screen assemblies 3 in total, with each pair of longitudinally adjacent filter screen assemblies 3 forming a group. The two groups of filter screen assemblies 3 are fixedly connected in a linear array in the through holes on the left and right sides inside the partition assembly 101. A servo motor B301 is installed at the bottom of each group of filter screen assemblies 3, and a fan blade assembly 3011 is installed on the top output shaft of the servo motor B301.

[0026] Among them, the servo motor B301 and the fan blade assembly 3011 together form the drive heat dissipation structure, and the bottom of the front opening of the housing mechanism 1 is hinged to the door assembly 1011, and the upper side of the front opening of the housing mechanism 1 is also hinged to the hatch assembly 1013. The interior of the door assembly 1011 has heat dissipation slots 1012 arranged in a rectangular array. The heat dissipation slots 1012 and the door assembly 1011 together form the air intake structure.

[0027] The hatch assembly 1013 has a through groove inside, and a glass window is embedded in the through groove. Both the hatch assembly 1013 and the front end of the box door assembly 1011 are fixedly connected to handle assemblies 1014. The inner side of the shell mechanism 1 has a through groove, and a support mechanism 2 is fixedly connected inside the through groove. There are two support mechanisms 2, which are fixedly connected to the front and rear sides inside the shell mechanism 1 in opposite directions.

[0028] Among them, guide roller assemblies 201 are rotatably connected to the inner side of the two support mechanisms 2. There are two guide roller assemblies 201 in total. The two guide roller assemblies 201 are rotatably connected to the inner side of the two support mechanisms 2 in a linear array. A servo motor A2011 is installed on the front end face of the support mechanism 2 on the front side. The servo motor A2011 is connected to the guide roller assembly 201 on the left side. A conveyor assembly 2012 for conveying the foaming wheel is also installed on the outer side of the two guide roller assemblies 201.

[0029] When in use, after the servo motor A2011 is started, it drives the left guide roller assembly 201 to rotate through the transmission structure, which in turn drives the conveyor assembly 2012 (conveyor belt) sleeved on the outside of the two guide roller assemblies 201 to run. The PU foaming wheel is placed on the conveyor assembly 2012 by hand and enters the cooling chamber from the front opening of the housing mechanism 1 along with the conveyor belt. The support mechanism 2 is fixed on the front and rear sides of the housing mechanism 1 to provide support for the guide roller assembly 201 and ensure the stability of the conveying process.

[0030] Servo motor B301 drives fan blade assembly 3011 to rotate at high speed, forming a negative pressure airflow inside housing mechanism 1. External cold air enters the cooling chamber (air intake structure) through heat dissipation slots 1012 on the door assembly 1011. After absorbing heat on the surface of the foaming wheel, it passes through filter screen assembly 3 (two sets in total, with two longitudinally arranged locations in each set) in partition assembly 101 to filter dust. Then, it is driven upward by fan blade assembly 3011 to be discharged, forming a "air intake-cooling-filtration-exhaust" circulating heat dissipation path. Filter screen assembly 3 can intercept impurities in the airflow to avoid contaminating the surface of the foaming wheel.

[0031] The door assembly 1013 can be opened or closed via the handle assembly 1014. Its embedded glass window facilitates observation of the conveying status of the foaming wheel inside the cooling chamber. When it is necessary to clean the filter assembly 3 or maintain the internal structure, the door assembly 1011 and the door assembly 1013 can be opened respectively via the handle assembly 1014. The former is used to access the bottom conveying area, and the latter is used to inspect the upper heat dissipation structure. Throughout the cooling process, the foaming wheel moves continuously with the conveying assembly 2012, avoiding prolonged limited cooling and enabling continuous batch production.
