Description

Technical Field

[0001] This utility model relates to the technical field of glue conveying equipment, and in particular to a glue conveying device. Background Technology

[0002] A large amount of glue is required in the production of composite fabrics. This glue is usually transported from glue tanks to designated locations via glue pumps and pipelines.

[0003] However, during the delivery process, the heat generated by the motor and pump body is transferred to the adhesive, causing the adhesive temperature to rise. This may cause the adhesive to undergo a premature chemical reaction and solidify, resulting in irreversible changes in viscosity. Consequently, this can lead to pipe blockage, uneven adhesive dispensing, and other consequences, affecting production efficiency. Utility Model Content

[0004] Therefore, there is a need for an adhesive conveying device to solve the technical problem that during the conveying process, the heat generated by the motor and pump body is transferred to the adhesive, causing the adhesive temperature to rise, which may trigger premature chemical reaction and solidification, irreversible changes in viscosity, and thus cause pipeline blockage, uneven adhesive dispensing, and other consequences, affecting production efficiency.

[0005] To achieve the above objectives, this utility model provides an adhesive conveying device, comprising:

[0006] The conveying assembly includes a conveying motor, a conveying pump, and a conveying pipe. The conveying motor is connected to the conveying pump, the inlet of the conveying pump is connected to an external glue tank, and the outlet of the conveying pump is connected to the inlet of the conveying pipe.

[0007] The heat dissipation assembly includes a housing, a coolant tank, and a circulating pump. The housing is fitted over the delivery pump and delivery pipe. The housing has a main inlet and a main outlet. The interior of the housing has a cooling channel. The main inlet and the main outlet are both connected to the cooling channel. The outlet of the coolant tank is connected to the main inlet through the circulating pump. The inlet of the coolant tank is connected to the main outlet. The cooling channel is used to cool the delivery pump and the delivery pipe.

[0008] Unlike existing technologies, the above-mentioned technical solution uses a circulating pump to create a closed-loop coolant system. The coolant flowing through the cooling channel continuously carries away the heat from the delivery pump and delivery pipe, achieving efficient cooling throughout the glue route. This effectively removes shear heat and conduction heat from the source, preventing the glue from curing, degenerating, or changing viscosity due to overheating during delivery, thus ensuring glue quality and process stability.

[0009] In one embodiment of this utility model, the cooling channel is spiral or S-shaped.

[0010] In this way, the meandering flow channel can significantly increase the flow path and residence time of the coolant in the casing, thereby fully exchanging heat with the delivery pipe and improving heat dissipation efficiency.

[0011] As one embodiment of the present invention, the housing includes a first heat dissipation shell and a second heat dissipation shell, the first heat dissipation shell and the second heat dissipation shell are fitted together and sleeved on the outside of the delivery pump and the delivery pipe, and the first heat dissipation shell and the second heat dissipation shell are sealed together.

[0012] The cooling channel includes a first cooling channel and a second cooling channel. The first heat dissipation shell has a first cooling channel inside, and the second heat dissipation shell has a second cooling channel inside.

[0013] Thus, the housing adopts a split structure, which can be detachably assembled with bolts or other fasteners, together wrapping around the delivery pump and delivery pipe, and the joint surfaces are sealed with sealing rings or other means. This makes the installation and maintenance of the equipment extremely convenient; simply opening the outer casing allows access to the internal delivery pump and delivery pipe.

[0014] In one embodiment of this utility model, a main liquid inlet is installed on the upper part of the first heat dissipation shell, a main liquid outlet is installed on the lower part of the second heat dissipation shell, and the first cooling channel is connected to the second cooling channel.

[0015] In this way, the coolant enters from the top, flows through the first cooling channel, then enters the second cooling channel, and finally flows out from the bottom. The series arrangement ensures that the coolant can flow through all areas that need heat dissipation and conforms to the efficient heat exchange principle of "low inlet, high outlet" or "high inlet, low outlet".

[0016] In one embodiment of this utility model, the first heat dissipation shell is hollow to form a first cooling channel, and the second heat dissipation shell is hollow to form a second cooling channel.

[0017] In this way, by setting up cooling channels to directly cover the heat dissipation shell, only a seal needs to be set at the connection between the first heat dissipation shell and the second heat dissipation shell, thus reducing the difficulty of connecting the first cooling channel and the second cooling channel.

[0018] In one embodiment of this utility model, both the first cooling channel and the second cooling channel are C-shaped and wavy. The first end of the first cooling channel is connected to the first end of the second cooling channel, and the tail end of the first cooling channel is connected to the tail end of the second cooling channel.

[0019] In this way, the beginning and end of the two C-shaped channels are connected to each other, forming a complete and complex cooling channel network that covers the entire shell, maximizing the heat exchange area.

[0020] As one embodiment of the present invention, the main liquid inlet includes a first liquid inlet and a second liquid inlet, the main liquid outlet includes a first liquid outlet and a second liquid outlet, and the first cooling channel and the second cooling channel are both S-shaped.

[0021] The first liquid inlet is installed on the upper part of the first heat dissipation shell, and the first liquid outlet is installed on the lower part of the first heat dissipation shell. Both the first liquid inlet and the first liquid outlet are connected to the first cooling channel.

[0022] The second liquid inlet is installed on the upper part of the second heat dissipation shell, and the second liquid outlet is installed on the lower part of the second heat dissipation shell. Both the second liquid inlet and the second liquid outlet are connected to the second cooling channel.

[0023] Thus, both the first and second cooling channels are S-shaped and independent of each other, forming parallel loops. The first inlet and the first outlet form an independent circulation with the first cooling channel; the second inlet and the second outlet form another independent circulation with the second cooling channel. This parallel arrangement reduces flow resistance, increases coolant flow rate, and achieves zoned and uniform cooling of the delivery pump and delivery pipes, resulting in more precise temperature control.

[0024] As one embodiment of this utility model, the heat dissipation assembly also includes a heat sink, which is installed outside the housing.

[0025] Thus, heat sinks are installed on the outer surface of the casing to increase the contact area with the air, allowing heat from the casing to be dissipated into the surrounding environment more quickly through convection and radiation.

[0026] As one embodiment of this utility model, the heat dissipation assembly also includes a guide plate, which is installed in the cooling channel.

[0027] Thus, the baffle plate is installed inside the cooling channel to guide and optimize the flow of coolant, avoid dead zones, and ensure that the coolant can flow evenly across all surfaces of the cooling channel, making heat dissipation more uniform and efficient.

[0048] During the delivery process, the heat generated by the motor and pump body is transferred to the adhesive, causing the adhesive temperature to rise. This may trigger a premature chemical reaction and solidification, resulting in irreversible changes in viscosity. Consequently, this can lead to pipe blockage, uneven adhesive dispensing, and other consequences, affecting production efficiency.

[0049] In view of this, this application provides an adhesive delivery device 100, including a delivery assembly 1 and a heat dissipation assembly 2. The delivery assembly 1 includes a delivery motor 11, a delivery pump 12, and a delivery pipe 13. The delivery motor 11 is drivenly connected to the delivery pump 12. The inlet of the delivery pump 12 is connected to an external adhesive tank 200, and the outlet of the delivery pump 12 is connected to the inlet of the delivery pipe 13. The heat dissipation assembly 2 includes a housing 21, a coolant tank 22, and a circulation pump 23. The housing 21 is fitted with... Outside the delivery pump 12 and delivery pipe 13, the housing 21 is provided with a main liquid inlet 213 and a main liquid outlet 214. The interior of the housing 21 has a cooling channel 215. The main liquid inlet 213 and the main liquid outlet 214 are both connected to the cooling channel 215. The outlet of the coolant tank 22 is connected to the main liquid inlet 213 through the circulation pump 23. The inlet of the coolant tank 22 is connected to the main liquid outlet 214. The cooling channel 215 is used to cool the delivery pump 12 and delivery pipe 13.

[0050] According to some embodiments of this application, please refer to Figures 1 to 6This embodiment relates to an adhesive conveying device 100, including a conveying assembly 1 and a heat dissipation assembly 2. The conveying assembly 1 includes a conveying motor 11, a conveying pump 12, and a conveying pipe 13. The conveying motor 11 is connected to the conveying pump 12. The inlet of the conveying pump 12 is connected to an external adhesive tank 200, and the outlet of the conveying pump 12 is connected to the inlet of the conveying pipe 13. The heat dissipation assembly 2 includes a housing 21, a coolant tank 22, and a circulating pump 23. The housing 21 is sleeved on the conveying assembly. Outside of the pump 12 and the delivery pipe 13, the housing 21 is provided with a main liquid inlet 213 and a main liquid outlet 214. The interior of the housing 21 has a cooling channel 215. The main liquid inlet 213 and the main liquid outlet 214 are both connected to the cooling channel 215. The outlet of the coolant tank 22 is connected to the main liquid inlet 213 through the circulating pump 23. The inlet of the coolant tank 22 is connected to the main liquid outlet 214. The cooling channel 215 is used to cool the delivery pump 12 and the delivery pipe 13.

[0051] The conveyor motor 11 and the conveyor pump 12 can be connected by chain and gear transmission. The conveyor motor 11 drives the conveyor pump 12 to pump the glue from the external glue tank through the glue inlet, and discharge it from the glue outlet to the conveyor pipe 13, and finally deliver it to the designated location through the conveyor pipe 13.

[0052] The heat dissipation assembly 2 includes a housing 21 that surrounds the delivery pump 12 and the delivery pipe 13, a coolant tank 22, and a circulation pump 23. The circulation pump 23 pumps coolant from the coolant tank 22 into the main inlet 213 of the housing 21, flows through the internal cooling channel 215, and returns to the coolant tank 22 from the main outlet 214, forming a circulating cooling system.

[0053] Optionally, an inlet valve is provided at the main inlet 213 and an outlet valve is provided at the main outlet 214.

[0054] The working principle of the glue delivery device 100 is as follows: the delivery motor 11 and the circulation pump 23 are started, and the delivery pump 12 begins to deliver the glue. At the same time, the coolant begins to circulate. The heat generated by the glue during delivery by the circulation pump 23 is quickly carried away by the flowing coolant, thereby keeping its temperature within a safe range and effectively preventing various problems caused by overheating.

[0055] Unlike existing technologies, the coolant in the above-mentioned technical solution forms a closed loop under the drive of the circulating pump 23. The coolant flowing through the cooling channel 215 continuously carries away the heat from the delivery pump 12 and the delivery pipe 13, achieving efficient cooling of the entire glue route. It can effectively remove shear heat and conduction heat from the source, preventing the glue from curing, degenerating or changing viscosity due to overheating during delivery, thus ensuring the glue quality and process stability.

[0056] like Figure 2 and Figure 3As shown, the cooling channel 215 is spiral or S-shaped.

[0057] In this way, the meandering flow channel can significantly increase the flow path and residence time of the coolant in the housing 21, thereby fully exchanging heat with the delivery pipe 13 and improving heat dissipation efficiency.

[0058] like Figures 4 to 6 As shown, the housing 21 includes a first heat dissipation shell 211 and a second heat dissipation shell 212. The first heat dissipation shell 211 and the second heat dissipation shell 212 are fitted together and sleeved on the outside of the delivery pump 12 and the delivery pipe 13, and the first heat dissipation shell 211 and the second heat dissipation shell 212 are sealed together. The cooling channel 215 includes a first cooling channel 2151 and a second cooling channel 2152. The first heat dissipation shell 211 has a first cooling channel 2151 inside, and the second heat dissipation shell 212 has a second cooling channel 2152 inside.

[0059] The first heat dissipation housing 211 and the second heat dissipation housing 212 can be detachably connected by bolts.

[0060] Thus, the housing 21 adopts a split structure, which can be detachably assembled together by bolts or other fasteners, and together wrap around the delivery pump 12 and the delivery pipe 13, with the joint surfaces sealed by sealing rings or other means. This makes the installation and maintenance of the equipment extremely convenient, as the internal delivery pump 12 and delivery pipe 13 can be accessed simply by opening the housing.

[0061] like Figures 4 to 6 As shown, the upper part of the first heat dissipation shell 211 is equipped with a main liquid inlet 213, the lower part of the second heat dissipation shell 212 is equipped with a main liquid outlet 214, and the first cooling channel 2151 is connected to the second cooling channel 2152.

[0062] The interiors of the first heat dissipation shell 211 and the second heat dissipation shell 212 together form a series cooling channel 215. The main liquid inlet 213 is located at the upper part of the first heat dissipation shell 211, and the main liquid outlet 214 is located at the lower part of the second heat dissipation shell 212. The coolant flow direction is: main liquid inlet 213 → first cooling channel 2151 → second cooling channel 2152 → main liquid outlet 214, thereby realizing full-process flow cooling of the entire enclosed area by the coolant.

[0063] In this way, the coolant enters from the top, flows through the first cooling channel 2151, then enters the second cooling channel 2152, and finally flows out from the bottom. The series arrangement ensures that the coolant can flow through all areas that need heat dissipation and conforms to the efficient heat exchange principle of "low inlet, high outlet" or "high inlet, low outlet".

[0064] like Figure 4As shown, the first heat dissipation shell 211 has a hollow interior forming a first cooling channel 2151, and the second heat dissipation shell 212 has a hollow interior forming a second cooling channel 2152.

[0065] Thus, by setting the cooling channel 215 to directly cover the heat dissipation shell, only a seal needs to be provided at the connection between the first heat dissipation shell 211 and the second heat dissipation shell 212, reducing the difficulty of connecting the first cooling channel 2151 and the second cooling channel 2152.

[0066] like Figure 5 As shown, both the first cooling channel 2151 and the second cooling channel 2152 are C-shaped and wavy. The first end of the first cooling channel 2151 is connected to the first end of the second cooling channel 2152, and the last end of the first cooling channel 2151 is connected to the last end of the second cooling channel 2152.

[0067] In this way, the beginning and end of the two C-shaped channels are connected to each other, forming a complete and complex cooling channel network covering the entire shell 21, maximizing the heat exchange area.

[0068] like Figure 6 As shown, the main liquid inlet 213 includes a first liquid inlet 2131 and a second liquid inlet 2132, and the main liquid outlet 214 includes a first liquid outlet 2141 and a second liquid outlet 2142. The first cooling channel 2151 and the second cooling channel 2152 are both S-shaped. The first liquid inlet 2131 is installed on the upper part of the first heat dissipation shell 211, and the first liquid outlet 2141 is installed on the lower part of the first heat dissipation shell 211. Both the first liquid inlet 2131 and the first liquid outlet 2141 are connected to the first cooling channel 2151. The second liquid inlet 2132 is installed on the upper part of the second heat dissipation shell 212, and the second liquid outlet 2142 is installed on the lower part of the second heat dissipation shell 212. Both the second liquid inlet 2132 and the second liquid outlet 2142 are connected to the second cooling channel 2152.

[0069] The housing 21 can also adopt a parallel flow channel pattern. At the same time, there are two corresponding coolant tanks and circulating pumps, with one coolant tank and one circulating pump corresponding to one cooling flow channel.

[0070] Thus, both the first cooling channel 2151 and the second cooling channel 2152 are S-shaped and independent of each other, forming a parallel loop. The first liquid inlet 2131 and the first liquid outlet 2141 form an independent loop with the first cooling channel 2151; the second liquid inlet 2132 and the second liquid outlet 2142 form another independent loop with the second cooling channel 2152. This parallel arrangement reduces flow resistance, increases coolant flow rate, and achieves zoned and uniform cooling of the delivery pump 12 and the delivery pipe 13, resulting in more precise temperature control.

[0071] According to some embodiments of this application, optionally, the heat dissipation assembly 2 further includes a heat sink, which is mounted outside the housing 21.

[0072] Thus, the heat sink is installed on the outer surface of the housing 21 to increase the contact area with the air, so that the heat on the housing 21 can be dissipated to the surrounding environment more quickly through convection and radiation.

[0073] According to some embodiments of this application, optionally, the heat dissipation assembly 2 also includes a guide plate, which is installed in the cooling channel 215.

[0074] Thus, the guide plate is installed inside the cooling channel 215 to guide and optimize the flow of coolant, avoid dead zones, and ensure that the coolant can flow evenly across all surfaces of the entire cooling channel 215, making heat dissipation more uniform and efficient.

[0075] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
