Description

Technical Field

[0001] The utility model relates to the technical field of cooling in the production and processing of cosmetics, and particularly relates to a circulating cooling air hood. Background Art

[0002] In the current common filling cosmetics, during their production and processing, it is generally necessary to cool and form the filled cosmetic material through a cooling device. The common cooling device cools the filled cosmetics by using cold air. Currently, the air-cooling cooling devices are all simple single-layer structures. A single-layer cover is added at a fixed station or on a production line to form a cooling station, and an air inlet and an air outlet are provided on the cover housing.

[0003] It is very difficult for the above-mentioned single-layer air-cooling cooling device to achieve the recycling of cold air, which will lead to an increase in energy consumption. At the same time, the single-layer air duct will directly expose the cosmetic products to the cold air, causing the surface of the products to cool too quickly and the wind speed to be too concentrated, resulting in an increase in the defective rate of the cosmetics. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a circulating cooling air hood with low energy consumption.

[0005] The technical solution adopted by the utility model to solve its technical problem is:

[0006] A circulating cooling air hood includes a double-layer structure of an outer cover housing and an inner cover. The inner cover is fixed inside the outer cover housing and forms an air hood interlayer sealed from the external environment between it and the outer cover housing. A number of air inlet small holes are regularly arranged on the front and rear side panels of the inner cover, and a cooling chamber is formed inside. An air inlet port and a return air port are respectively arranged at the head and tail ends of the outer cover housing. The air inlet port is communicated with the air hood interlayer, and the return air port is communicated with the cooling chamber.

[0007] The front and rear sides between the inner cover and the outer cover housing are isolated and fixed by a number of positioning columns to form the air hood interlayer.

[0008] Preferably, the number of positioning columns is regularly and vertically arranged at the four corners of the inner cover and the outer cover housing.

[0009] Furthermore, the bottom surfaces of the number of positioning columns are horizontal to form the front and rear bases of the circulating cooling air hood. The front and rear side panels of the inner cover are fixed to the inner sides of the front and rear bases, and the front and rear side panels of the outer cover housing are fixed to the outer sides of the front and rear bases. The circulating cooling air hood is placed on the production line brackets on both sides of the production line through its front and rear bases, so as to quickly install the circulating cooling air hood on the production line. The conveyor belt between the production line brackets is located in the cooling chamber of the circulating cooling air hood.

[0010] Furthermore, the lower ends of the front and rear side panels of the outer cover housing extend beyond the lower end of the base of the circulating cooling air hood, so that the front and rear side panels of the outer cover housing are arranged outside the assembly line support.

[0011] Furthermore, the inner cover includes inner cover side panels on both the front and rear sides and an inner cover top panel at the top. The inner cover side panels on both the front and rear sides and the inner cover top panel are regularly fixed and formed by a number of inner cover suspension beams; the outer cover housing also includes outer cover side panels on both the front and rear sides and an outer cover top panel at the top. The outer cover side panels on both the front and rear sides and the outer cover top panel are regularly fixed and formed by a number of positioning columns and a number of outer cover suspension beams; the number of positioning columns and the number of outer cover suspension beams isolate and fix the outer cover housing and the inner cover to form the air hood sandwich layer sealed from the external environment.

[0012] Preferably, the number of air inlet small holes are regularly arranged at the middle and lower positions of the inner cover side panels.

[0013] Furthermore, adjustment plates are flexibly arranged on both the head and tail sides of the circulating cooling air hood. Positioning slotted holes are arranged on the adjustment plates, and the adjustment plates are flexibly arranged on the circulating cooling air hood by bolts passing through the positioning slotted holes.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The circulating cooling air hood of the present utility model adopts a double-layer structure design of an inner cover and an outer cover, forming an air hood sandwich layer between the inner cover and the outer cover. Then, a number of air inlet small holes are regularly arranged on the side panels on both the front and rear sides of the inner cover. By delivering cold air into the air hood sandwich layer, the cold air flows forward in the air hood sandwich layer and blows into the cooling chamber inside the inner cover through the number of air inlet small holes on the side panels on both the front and rear sides of the inner cover, so as to cool the products conveyed on the assembly line located in the cooling chamber with cold air. Therefore, the cold air sent in from the air inlet port will not come into contact with the cosmetic material body immediately, and thus the product defects caused by rapid cooling can be avoided. Moreover, the cold air at the air inlet port will not directly contact the product immediately. The cold air at the air inlet port needs to be transmitted through the number of air inlet small holes on the front and rear side panels of the inner cover to form a cooling chamber inside the inner cover, and the products on the assembly line inside are cooled, so that the surface of the product can be prevented from cooling too fast and the wind speed from being too concentrated, resulting in an increase in the defective rate.

[0016] 2. The circulating cooling air hood of the present utility model regularly arranges a number of positioning columns between the side panels on both the front and rear sides of the inner cover and the outer cover housing, and isolates and fixes them through the number of positioning columns to form an air hood sandwich layer. Therefore, the number of positioning columns also serves as the front and rear installation bases of the circulating cooling air hood. By placing the front and rear installation bases of the circulating cooling air hood on the assembly line supports on both sides of the assembly line, it can be quickly installed on the assembly line workstations that need to be cooled.

[0017] 3. The circulating cooling air hood of the present utility model forms a positioning groove for the assembly line bracket between the front and rear side panels of the outer casing by extending the lower end of the outer casing beyond the lower ends of the front and rear mounting bases. By arranging the front and rear side edges of the outer casing extending beyond the lower ends of the mounting bases on the outer sides of the assembly line bracket, not only the stability of the installation of the circulating cooling air hood on the assembly line is improved, but also the position of the circulating cooling air hood on the assembly line is convenient to adjust.

[0018] 4. The present utility model is flexibly provided with adjusting plates on both the head and tail sides of the circulating cooling air hood, so that the height distance between the adjusting plates and the assembly line can be adjusted and controlled according to the height of the cosmetic products, thereby minimizing the loss of cold air inside the air hood as much as possible.

[0027] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following describes in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] As Figures 1-4 shown, the present utility model provides a circulating cooling air hood, including a double-layer structure of an outer hood housing 101 and an inner hood 104. The inner hood 104 is fixed inside the outer hood housing 101 and forms an air hood interlayer 105 with the outer hood housing. A number of air inlet small holes 1041 are regularly arranged on the front and rear side panels of the inner hood 104, and a cooling chamber 106 is formed inside. Air inlet ports 102 and a return air port 103 are respectively arranged at the head and tail ends of the outer hood housing 101. The air inlet port 102 is internally communicated with the air hood interlayer 105 between the outer hood housing and the inner hood, and the return air port 103 is internally communicated with the cooling chamber 106 inside the inner hood.

[0030] Among them, in actual use, the air inlet port 102 is connected to the air outlet of an industrial refrigeration fan through an air inlet pipeline, and the return air port 103 is connected to the air return port of the industrial refrigeration fan through a return air pipeline. The refrigeration fan conveys cold air into the air hood interlayer 105 through the air inlet pipeline and the air inlet port. The cold air flows forward in the air hood interlayer (i.e., flows to the Figure 2 left side in the figure), and the cold air flowing in the air hood interlayer then flows into the cooling chamber 106 inside the inner hood through a number of air inlet small holes 1041 on the front and rear side panels of the inner hood, and cools the cosmetic products conveyed on the production line 2 in the cooling chamber with cold air. The return air port extends into the cooling chamber inside the inner hood through structures such as flanges, so as to pump the air in the cooling chamber to the industrial refrigeration machine for cooling through the return air port.

[0031] The utility model adopts a double-layer structure of an inner cover and an outer cover, forming an air duct sandwich layer between the inner cover and the outer cover. Then, a number of air inlet small holes are regularly arranged on the side panels on the front and rear sides of the inner cover. By conveying cold air into the air duct sandwich layer, the cold air flows forward in the air duct sandwich layer and blows into the cooling chamber inside the inner cover through a number of air inlet small holes on the side panels on the front and rear sides of the inner cover, so as to perform cold air cooling on the products conveyed on the production line located in the cooling chamber.

[0032] As Figure 1 and Figure 2 shown, the air inlet port 102 and the air return port 103 are respectively arranged on the right side and the left side of the circulating cooling air duct. During the use process, the conveying direction of the production line 2 is from left to right. Therefore, the cold air sent in by the air inlet port will not contact the cosmetic material body immediately, and thus the defects caused by rapid cooling can be avoided. Moreover, the cold air at the air inlet port will not directly contact the product immediately. The cold air at the air inlet port needs to be conveyed through a number of air inlet small holes on the front and rear side panels of the inner cover to form a cooling chamber inside the inner cover, and the products on the production line inside it are cooled, so that the surface of the product can be prevented from cooling too fast and the wind speed from being too concentrated, resulting in an increase in the defective rate.

[0033] The utility model sets the air inlet port at the end (right side) of the production line and the air return port at the head (left side) of the production line. Through the double-layer circulating cold air structure, there is a certain temperature difference between the internal temperatures at both ends, and the temperature change is a process of slowly getting colder. Therefore, for the just-filled cosmetic products, their surface temperatures are relatively high. When they are conveyed from the left side to the right side of the production line, their surface temperatures are gradually and slowly reduced and cooled, thus avoiding the defective rate of the products. Moreover, through the circulating design, the energy consumption can be reduced and the cost can be saved.

[0034] Furthermore, in order to facilitate the installation of the circulating cooling air duct onto the production line 2, as Figure 3 and Figure 4 shown, a number of positioning columns 107 are arranged between the outer cover shell 101 and the inner cover 104. The number of positioning columns 107 is regularly arranged between the side panels on the front and rear sides of the outer cover shell and the inner cover, so as to separate and fix the outer cover shell and the inner cover, and form an air duct sandwich layer 105 therebetween. The lengths of the number of positioning columns are the same and the bottom surfaces are horizontally arranged, thus forming the mounting seat of the circulating cooling air duct. By placing the mounting seat formed by the number of fixing columns on both sides in front and rear onto the production line brackets 202 on both sides of the production line 2, the rapid installation of the circulating cooling air duct onto the production line can be completed, thus facilitating the installation of the circulating cooling air duct onto the production line.

[0035] Among them, the side panels on the front and rear sides of the inner cover are fixed inside a number of positioning posts, and the side panels on the front and rear sides of the outer cover housing are fixed outside the number of positioning posts. Moreover, the length of the side panel of the inner cover is less than the length of the positioning post, thereby forming an air duct sandwich layer between the inner cover and the outer cover housing.

[0036] Furthermore, in order to improve the stability of the circulating cooling air duct and the production line, the length of the side panels on the front and rear sides of the outer cover housing 101 is greater than the length of the positioning post, so as to facilitate the front and rear side panels of the outer cover housing to extend out of the bottom end of the positioning post. Thus, it can be convenient for the front and rear side panels of the outer cover housing to be respectively arranged outside the production line support profiles on the front and rear sides of the production line, facilitating the outer cover housing to be clamped on the profiles on the front and rear sides of the production line and preventing the air duct from falling. It also facilitates the left and right movement of the circulating cooling air duct on the production line support for positioning. The circulating cooling air duct can quickly adjust the front and rear positions of the air duct in the movement direction of the production line through the outer cover housing, so as to achieve a more ideal production effect.

[0037] As Figure 4 shown, the inner cover 104 includes inner cover side panels 1042 on the front and rear sides and an inner cover top panel 1043 on the top. The front and rear inner cover side panels and the inner cover top panel are fixed and formed by a number of inner cover suspension beams 108, forming a rectangular structure or an arched structure with open ends and bottom. Among them, the inner cover suspension beam 108 includes a crisscrossed suspension beam structure. The front and rear inner cover side panels are arranged on the front and rear sides of the suspension beam structure, and a number of air inlet small holes are regularly arranged on them. The air inlet small holes are preferably arranged at the middle and lower positions of the side panel, and the inner cover top panel on the top is sealed, so that the cold air only enters the cooling chamber through the air inlet small holes on the inner cover side panel.

[0038] Furthermore, a number of positioning posts 107 are arranged at the four corners of the side panels on the front and rear sides of the inner cover, so as to fix the inner cover in the outer cover housing through the positioning posts at the four corners. The number of positioning posts separates the inner cover and the outer cover housing to form an air duct sandwich layer.

[0039] Furthermore, as Figure 4 shown, a suspension beam is also arranged between the positioning posts on both sides of the head and tail ends of the inner cover to form an outer cover suspension beam 109, thus facilitating the fixation and formation of the top panel of the outer cover housing.

[0040] As Figure 3 and Figure 4As shown, the positioning columns at the four corners between the inner cover and the outer cover shell can, on the one hand, conveniently isolate and fix the inner cover and the outer cover shell to form a hood interlayer between them; on the other hand, the hood interlayer can be sealed from the outside by combining with the outer cover suspension beam 109 connected to the upper ends of both ends to reduce the loss of cold air in the hood interlayer. In addition, the cold air transported into the hood interlayer is limited to enter the internal cooling chamber only through the several air inlet holes on the inner cover side panels by blocking the outer cover side panels outside the positioning columns.

[0041] Furthermore, in order to avoid deformation of the circulating cooling hood and facilitate its transportation or assembly, when the production line is relatively long, the inner hood and the outer hood shell can be modularly designed. Figure 3 and Figure 4 As shown, two groups of inner cover structures are spliced ​​together. The two inner covers are spliced ​​together by sharing a longitudinal cantilever beam, and then positioning columns 107 are set at the four corners of each inner cover and fixed to them. Two groups of corresponding outer cover shells are also set, and the two groups of outer cover side panels 1011 are respectively fixed to the outside of the fixing columns on the outside of the two groups of inner covers. The modular design can facilitate the transportation of the circulating cooling hood components and facilitate rapid assembly. At the same time, it can also avoid the problem of deformation during use due to the inner cover or outer cover components being too long.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown in FIG. 1 , the front and rear sides of the circulating cooling hood 2 are also flexibly provided with adjustment plates 3, so that the height distance between the adjustment plates 3 and the assembly line can be adjusted according to the height of the cosmetic product, thereby minimizing the loss of cold air inside the hood.

[0043] Locking bars are provided on both sides of the adjusting plate 3, and screws or bolts are passed through the holes to fix it to the circulating cooling hood. The adjusting plate can be released by loosening the bolts, and then its height can be adjusted through the holes, and it can be fixed by tightening the bolts.

[0044] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.​​​
