Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispensing technology, and in particular to a dispensing valve cooling mechanism. Background Technology
[0002] With advancements in technology, dispensing processes are now widely used in product manufacturing. Dispensing primarily consists of adhesive, dispensing equipment, and dispensing valves. Some adhesives used in dispensing tend to cure at room temperature, making dispensing difficult. Cooling devices are often used in these cases, but the low temperature and large temperature difference with the surrounding environment can cause condensation to form on the surface. This condensation dripping onto the product can damage or cause defects. Current cooling devices typically collect condensation to prevent dripping, but this doesn't address the root cause of the condensation problem. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a dispensing valve cooling mechanism, which can fundamentally solve the problem of condensation and dripping that affects product quality. It can also make the disassembly and assembly process of the dispensing tube visible while ensuring the heat insulation effect between the heat-conducting shell and the cooling body.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dispensing valve cooling mechanism, comprising: a cooling body that is in contact with the cooling surface of a cooling plate; a heat-conducting shell that is spaced apart from the cooling body is provided on the outer side of the cooling body; the heat-conducting shell is in contact with at least one heating component; a receiving groove for embedding a dispensing tube is formed on the surface of the cooling body opposite to the cooling plate; a strip-shaped through hole corresponding to the receiving groove is formed on the side wall of the heat-conducting shell opposite to the cooling plate; and a strip block is detachably embedded in the receiving groove and press-fitted with the dispensing tube in the receiving groove.
[0005] The following are further improvements to the above technical solution: 1. In the above scheme, a heat dissipation plate is provided on the side of the cooling chip opposite to the cooling body, which is in contact with and connected to the heat dissipation surface of the cooling chip. The heat-conducting shell is in contact with and connected to the heat dissipation plate, so that the inner wall of the heat-conducting shell and the cooling body and the heat dissipation plate form a heat insulation cavity.
[0006] 2. In the above scheme, at least one heating rod is embedded in the heat-conducting shell.
[0007] 3. In the above scheme, the strip block further includes a body portion for pressing and engaging with the mixing tube and an outwardly protruding portion formed on the side of the body portion opposite to the mixing tube.
[0008] 4. In the above scheme, the body of the strip block embedded in the strip-shaped through hole is tightly fitted with the inner wall of the strip-shaped through hole.
[0009] 5. In the above scheme, the strip block is an elastic block.
[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a dispensing valve cooling mechanism. The cooling body is covered by a heat-conducting shell spaced apart from it. The heat-conducting shell is in contact with at least one heating element. A receiving groove for embedding a mixing tube is formed on the surface of the cooling body opposite to the cooling plate. A strip-shaped through hole corresponding to the receiving groove is formed on the side wall of the heat-conducting shell opposite to the cooling plate. A strip-shaped block is detachably embedded in the receiving groove and press-fitted with the mixing tube within the groove. By heating the heat-conducting shell spaced apart from the cooling body, the temperature difference between the cooling body and the surrounding environment can be reduced while maintaining the cooling effect, and the heat-conducting shell can be prevented from being affected by the low temperature of the cooling body. To address situations with significant temperature differences from the environment, this design fundamentally solves the problem of condensation dripping from the cooling unit and adjacent components during the dispensing process, which negatively impacts product quality. It also ensures effective insulation between the heat-conducting shell and the cooling unit while allowing visualization of the disassembly and assembly process of the mixing tube. Furthermore, a heat dissipation plate is located on the side of the cooling chip opposite to the cooling unit, contacting and connecting with the heat dissipation surface of the cooling chip. The heat-conducting shell is in contact with this heat dissipation plate, thus forming a heat-insulating cavity between the inner wall of the heat-conducting shell, the cooling unit, and the heat dissipation plate. The heat from the heat dissipation plate heats the heat-conducting shell, further improving the heat dissipation efficiency of the heat dissipation plate and saving energy.

Detailed Implementation
[0013] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.
[0014] Example 1: A dispensing valve cooling mechanism includes: a cooling body 1 that is in contact with the cooling surface of a cooling plate 2; a heat-conducting shell 3 that is spaced apart from the cooling body 1 is provided on the outer side of the cooling body 1; the heat-conducting shell 3 is in contact with at least one heating component; a receiving groove 6 for embedding a dispensing tube 100 is provided on the surface of the cooling body 1 opposite to the cooling plate 2; a strip-shaped through hole 14 corresponding to the receiving groove 6 is provided on the side wall of the heat-conducting shell 3 opposite to the cooling plate 2; and a strip-shaped block 15 is detachably embedded in the receiving groove 6 and press-fitted with the dispensing tube 100 in the receiving groove 6. Aluminum has good thermal conductivity, which allows the surface temperature of the refrigeration unit to remain close to room temperature. Using aluminum for heat conduction prevents the shell temperature from dropping too low, and prevents water molecules from condensing due to excessive temperature differences when air comes into contact with the metal surface.
[0015] At least one heating rod is embedded in the aforementioned heat-conducting housing 3.
[0016] The aforementioned strip block 15 further includes a body portion 151 for press-fitting with the mixing tube 100 and an outwardly protruding portion 152 formed on the side of the body portion 151 opposite to the mixing tube 100.
[0017] The body portion 151 of the strip block 15 embedded in the strip-shaped through hole 14 is tightly fitted with the inner wall of the strip-shaped through hole 14; the strip block 15 is an elastic block.
[0018] At least one temperature sensor 11 is embedded in the aforementioned refrigeration body 1, which can acquire the temperature of the refrigeration body in real time and control and adjust it as needed to maintain the stability of the refrigeration temperature. The specific control and adjustment methods can be adopted using existing technologies, and will not be elaborated here.
[0019] Example 2: A dispensing valve cooling mechanism includes: a cooling body 1 that is in contact with the cooling surface of a cooling plate 2; a heat-conducting shell 3 that is spaced apart from the cooling body 1 is provided on the outer side of the cooling body 1; the heat-conducting shell 3 is in contact with at least one heating component; a receiving groove 6 for embedding a dispensing tube 100 is provided on the surface of the cooling body 1 opposite to the cooling plate 2; a strip-shaped through hole 14 corresponding to the receiving groove 6 is provided on the side wall of the heat-conducting shell 3 opposite to the cooling plate 2; and a strip-shaped block 15 is detachably embedded in the receiving groove 6 and press-fitted with the dispensing tube 100 in the receiving groove 6. The heat-conducting shell remains hot and will not change due to the low temperature of the internal cooling unit, preventing the temperature of the heat-conducting shell from becoming too low. When air comes into contact with the surface of the heat-conducting shell, water molecules will not condense due to excessive temperature difference. The insulation cavity is filled with heat-insulating cotton or filled with foam insulation adhesive, forming a structure similar to a refrigerator. In principle, this avoids the formation of condensate, making it more stable and durable than adding a water collection device.
[0020] A heat dissipation plate 7 is provided on the side of the cooling chip 2 opposite to the cooling body 1, which is in contact with the heat dissipation surface of the cooling chip 2. The heat-conducting shell 3 is in contact with the heat dissipation plate 7, so that the inner wall of the heat-conducting shell 3, the cooling body 1, and the heat dissipation plate 7 form a heat insulation cavity 4. The cooling chip has two sides, a hot side and a cold side. The hot side of the cooling chip carries away some of the heat through the water flow in the heat sink. While ensuring the cooling effect, the heat sink itself still has a relatively hot and stable temperature close to room temperature. This heat is reused to heat the heat-conducting shell. The cold side of the cooling chip is used to cool the adhesive in the mixing tube. The heat sink plate, which is in contact with the hot surface of the cooling chip, is made of aluminum and is connected to a heat-conducting shell, which is also made of aluminum. The heat sink plate, which is close to room temperature, is transferred to the heat-conducting shell and encloses the cooling body.
[0021] The aforementioned heat sink 7 is located on the side of the cooling chip 2 opposite to the cooling body 1 and has interconnected liquid inlet channel 121 and liquid outlet channel 122. Water circulation in the channels is achieved through external components such as pumps to cool the cooling chip surface. Compared with directly using external heat dissipation equipment to cool the cooling chip, the combination of water circulation and a large-area heat sink results in a larger heat dissipation area and is more convenient to install.
[0022] The aforementioned heat sink 7 has a mounting slot 71 for embedding the cooling chip 2.
[0023] The edges of the aforementioned heat-conducting housing 3 are all in contact with the surface of the heat sink 7.
[0024] The aforementioned refrigeration body 1 and heat-conducting shell 3 are each fixedly installed on the heat sink 7 by bolts. The two side surfaces of the refrigeration chip 2 located between the refrigeration body 1 and the heat sink 7 are in close contact with the refrigeration body 1 and the heat sink 7, respectively.
[0025] The aforementioned refrigeration body 1, heat-conducting shell 3, and heat sink 7 are all metal bodies with high thermal conductivity.
[0026] The aforementioned refrigeration body 1 is a brass refrigeration body, the heat-conducting shell 3 is a copper shell, and the heat dissipation plate 7 is an aluminum plate; The mixing tube is wrapped with a brass refrigeration body to ensure uniform cooling and improve the uniformity of cooling of the adhesive liquid.
[0027] The aforementioned heat-conducting housing 3 is provided with a clearance through hole 31 for the rubber tube 100 to pass through.
[0028] The aforementioned heat insulation cavity 4 is filled with heat insulation material to further prevent heat conduction between the refrigeration body and the heat-conducting shell, ensuring that the temperature difference between the two and the surrounding environment is small, and preventing the generation of condensation. The aforementioned heat insulation material is heat insulation cotton.
[0029] The cooling chip has two sides, a hot side and a cold side. The hot side of the cooling chip carries away some of the heat through the water flow in the heat sink. While ensuring the cooling effect, the heat sink itself still has a relatively hot and stable temperature close to room temperature. This heat is reused to heat the heat-conducting shell. The cold side of the cooling chip is used to cool the adhesive in the mixing tube. Aluminum has good thermal conductivity, which allows the surface temperature of the refrigeration unit to be close to the room temperature. Using aluminum for heat conduction prevents the temperature of the shell from getting too low, and prevents water molecules from condensing due to excessive temperature difference when air comes into contact with the metal surface. In existing technologies, plastic insulation material is wrapped around the outside of the refrigeration unit, but water droplets will still form on the surface of the insulation material over time. The mixing tube is wrapped with a brass refrigeration body to ensure uniform cooling and improve the uniformity of cooling of the adhesive liquid. The heat sink plate that is in contact with the hot surface of the cooling chip is made of aluminum plate and is connected to the heat-conducting shell, which is also made of aluminum. The heat sink plate, which is close to room temperature, is transferred to the heat-conducting shell and wraps the cooling body. The heat-conducting shell remains hot and will not change due to the low temperature of the internal cooling unit, preventing the temperature of the heat-conducting shell from becoming too low. When air comes into contact with the surface of the heat-conducting shell, water molecules will not condense due to excessive temperature difference. The insulation cavity is filled with heat-insulating cotton or filled with foam insulation adhesive, forming a structure similar to a refrigerator. In principle, this avoids the formation of condensate, making it more stable and durable than adding a water collection device.
[0030] When the above-mentioned dispensing valve cooling mechanism is used, by heating the heat-conducting shell that is spaced apart from the cooling body, the temperature difference between the cooling body and the surrounding environment can be reduced while ensuring the cooling effect. This also avoids the situation where the heat-conducting shell is affected by the low temperature of the cooling body, resulting in a large temperature difference between the shell and the environment. This fundamentally solves the problem of condensation dripping from the cooling body and adjacent components during the dispensing process, which affects product quality. It also allows for visualization of the disassembly and assembly process of the mixing tube while ensuring the heat insulation effect between the heat-conducting shell and the cooling body. Furthermore, by heating the heat-conducting shell with heat from the heat sink, the heat dissipation efficiency of the heat sink can be further improved and energy consumption can be saved.
[0031] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
