Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and more specifically to an adhesive application device. Background Technology

[0002] In refrigeration and heating equipment, water-cooled water heaters typically integrate both water and refrigerant systems to achieve temperature control through heat exchange between water and the refrigerant. However, statistics on water heater malfunctions show that leaks such as refrigerant and water leaks are frequent, becoming a key factor affecting product quality and equipment operational safety. Therefore, ensuring the airtightness of both the water and refrigerant systems is crucial for preventing leaks.

[0003] Currently, in water and refrigerant systems, safety valves and automatic air release valves commonly use threaded connections to connect with other components. To ensure reliable sealing at these connections, the traditional method is to manually apply pipe thread sealant to the threads. However, manual application can result in uneven application, potentially leading to insufficient sealant coverage in certain areas and increasing the risk of leakage.

[0004] Therefore, the industry urgently needs a glue application device that can assist in the uniform application of glue to the threaded parts, ensuring the tightness of the seal between the threaded parts and the connecting components. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue application device to solve the technical problem that manual glue application can easily lead to insufficient local glue coverage on the workpiece.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a glue application device, comprising: a mounting base and two glue application mechanisms symmetrically connected to the mounting base; each glue application mechanism includes: a glue gun, a placement sleeve, a delivery tube, and a pressing assembly; the glue gun is hinged to the mounting base, the placement sleeve is connected to the glue outlet end of the glue gun, and the placement sleeves of the two glue application mechanisms abut against each other to form a receiving space for accommodating a workpiece; the delivery tube is installed on the mounting base and communicates with the interior of the glue gun; one end of the pressing assembly is connected to the end of the glue gun near the placement sleeve, and the other end is movably connected to the delivery tube.

[0008] In one embodiment, the placement sleeve is arranged in an arc shape.

[0009] In one embodiment, the placement sleeve is provided with an inlet hole and a plurality of outlet holes. The inlet hole and the outlet holes are respectively located on the side wall of the placement sleeve near and away from the glue gun. The inlet hole connects the glue gun and the outlet holes.

[0010] In one embodiment, the placement sleeve is hinged to the dispensing end of the glue gun.

[0011] In one embodiment, the glue gun has a hinge and a telescopic rod arranged sequentially from top to bottom at the glue dispensing end, and the placement sleeve is hinged to the hinge and the telescopic rod.

[0012] In one embodiment, the pressing assembly includes a pressure rod and a piston; the piston is disposed inside the delivery tube, one end of the pressure rod is connected to the bottom of the glue gun, and the other end is hinged to the piston.

[0013] In one embodiment, the pushing assembly further includes a connecting rod; one end of the connecting rod is hinged to the end of the pressure rod away from the glue gun, and the other end is hinged to the piston.

[0014] In one embodiment, the pressure rod sleeve is provided with a return spring.

[0015] In one embodiment, the delivery tube includes a compression tube and a connecting hose; the pushing assembly is movably connected inside the compression tube, and the two ends of the connecting hose are respectively connected to the output end of the compression tube and the end of the glue gun away from the placement sleeve.

[0016] In one embodiment, the compression tube is disposed within the mounting base; the compression tube is arranged horizontally.

[0017] The advantages of this utility model compared with the prior art are as follows: By setting up a delivery pipe and a pushing component, the glue gun is pressed down when the workpiece comes into contact with the placement sleeve, thereby driving the pushing component to push the air in the delivery pipe, so as to squeeze the glue in the glue gun onto the placement sleeve.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0035] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0036] See Figure 1-6 As shown, this embodiment discloses an adhesive application device.

[0037] The adhesive applicator of this embodiment is suitable for applying adhesive to threaded connections of valves such as safety valves and automatic exhaust valves, or to workpieces with external threads such as threaded pipes, screws, and bolts. It has a simple structure, requires no power mechanism, resulting in lower production costs, and helps to achieve uniform adhesive application to the workpiece, thereby improving the system's sealing performance and the equipment's reliability.

[0038] The adhesive applicator of this embodiment includes: a mounting base 1 and two adhesive applicators symmetrically connected to the mounting base 1; the adhesive applicator includes: a glue gun 2, a placement sleeve 3, a delivery tube 4, and a pressing component 5; the glue gun 2 is hinged to the mounting base 1, the placement sleeve 3 is connected to the glue outlet end of the glue gun 2, and the placement sleeves 3 of the two adhesive applicators abut against each other to form a receiving space for accommodating the workpiece 6; the delivery tube 4 is installed on the mounting base 1 and communicates with the interior of the glue gun 2; one end of the pressing component 5 is connected to the end of the glue gun 2 near the placement sleeve 3, and the other end is movably connected to the delivery tube 4.

[0039] In practice, the threaded portion of the workpiece 6 is placed on the placement sleeves 3 of the two adhesive application mechanisms. The placement sleeves 3 are pressed down so that the adhesive is pushed onto the placement sleeves 3 under the action of the pushing component 5 and the conveying pipe 4. The placement sleeves 3 are rotated so that the outer periphery of the threaded portion is in contact with the placement sleeves 3, or the placement sleeves 3 are pressed down so that the outer periphery of the threaded portion is completely wrapped by the two placement sleeves 3. The workpiece 6 with adhesive applied is taken out from between the two placement sleeves 3 to complete the adhesive application of the workpiece 6.

[0040] The adhesive applicator in this embodiment, by setting up a delivery pipe 4 and a pressing component 5, allows the glue gun 2 to be pressed down when the workpiece 6 comes into contact with the placement sleeve 3. This, in turn, drives the pressing component 5 to push the air in the delivery pipe 4, thereby squeezing the glue in the glue gun 2 onto the placement sleeve 3. By manually or mechanically rotating the workpiece 6, or by pressing the workpiece 6 down onto the placement sleeve 3 until it is completely wrapped by the two placement sleeves 3, the workpiece 6 can be glued in all directions. This ensures the coverage and uniformity of the sealant on the workpiece 6, helps to improve the tightness of the connection between the workpiece 6 and the connecting parts, and thus improves the quality of the equipment and the safety of operation.

[0041] Specifically, the placement sleeve 3 is arranged in an arc shape. The arc shape of the placement sleeve 3 helps to improve the fit between the placement sleeve 3 and the workpiece 6, and helps to improve the smoothness and uniformity of gluing.

[0042] Preferably, the end of the placement sleeve 3 furthest from the glue gun 2 is arranged in an arc shape to adapt to the shape of the workpiece 6. The placement sleeve 3 is arranged to adapt to the shape of the workpiece 6, which ensures that the glue can be evenly distributed on the outer periphery of the workpiece 6. This can avoid uneven glue application or omissions, as well as avoid excessive local glue application and waste of sealant, effectively saving glue application costs for the workpiece 6.

[0043] Preferably, the end of the placement sleeve 3 furthest from the glue gun 2 is semi-circular, and the two placement sleeves 3 abut against each other to form a circular receiving space. The circular receiving space helps to completely surround the workpiece 6, so as to ensure that the threaded part of the workpiece 6 can be completely covered with glue.

[0044] Specifically, the placement sleeve 3 is provided with an inlet hole 31 and several outlet holes 32. The inlet hole 31 and outlet holes 32 are respectively located on the side wall of the placement sleeve 3 near and away from the glue gun 2. The inlet hole 31 connects the glue gun 2 and the outlet holes 32. The sealant in the glue gun 2 flows from the outlet end of the glue gun 2 through the inlet hole 31 to the outlet holes 32, allowing the sealant to diffuse from the outlet holes 32 to the side wall of the placement sleeve 3, and then contact and adhere to the surface of the threaded portion of the workpiece 6. The outlet holes 32 are distributed at the end of the placement sleeve 3 away from the glue gun 2, further improving the uniformity of the sealant coating on the workpiece 6.

[0045] Specifically, the placement sleeve 3 is hinged to the glue outlet end of the glue gun 2. The hinge of the placement sleeve 3 to the glue gun 2 allows the placement sleeve 3 to rotate relative to the glue gun 2, which helps to adjust the angle of the placement sleeve 3 and adjust the distance between the placement sleeves 3 of the two glue application mechanisms. This facilitates the separation or contact of the two placement sleeves 3, which helps to improve the ease with which the workpiece 6 enters or leaves the receiving space, thereby improving the glue application efficiency.

[0046] Specifically, the glue gun 2 has a hinge 21 and a telescopic rod 22 arranged sequentially from top to bottom at the glue dispensing end. The length of the hinge 21 is less than the length of the telescopic rod 22. The placement sleeve 3 is hinged to the hinge 21 and the telescopic rod 22. The top and bottom of the placement sleeve 3 are hinged to the glue gun 2, which improves the connection stability of the placement sleeve 3. The hinge 21 and the telescopic rod 22 limit the rotation angle of the placement sleeve 3, which facilitates the adjustment of the placement sleeve 3 to adapt to the angle and force of the workpiece 6 picking up and placing. When the top of the placement sleeve 3 abuts against the hinge part 21 and the telescopic rod 22 extends to its maximum distance, the tops of the two placement sleeves 3 move away from each other, opening the receiving space and facilitating the entry of the workpiece 6 from the top of the receiving space. After the workpiece 6 enters the receiving space, the placement sleeve 3 is pressed down further, causing the bottom of the placement sleeve 3 to be subjected to pressure from the outside of the receiving space, causing the telescopic rod 22 to retract, which in turn drives the top of the placement sleeve 3 to rotate towards the receiving space, bringing the tops of the placement sleeves 3 closer together and facilitating the fit of the placement sleeve 3 against the outer periphery of the workpiece 6. After the workpiece 6 is coated with adhesive, the workpiece 6 is lifted up, causing the top of the placement sleeve 3 to be subjected to a resisting force from the outside of the receiving space, causing the tops of the two placement sleeves 3 to move away from each other, so that the workpiece 6 can leave the receiving space.

[0047] Specifically, there are two hinges 21 and two telescopic rods 22. The two hinges 21 are symmetrically arranged at the top of the glue gun 2's glue outlet, and the two telescopic rods 22 are symmetrically hinged at the bottom of the glue gun 2's glue outlet. The top of the placement sleeve 3 is hinged to the two hinges 21, and the bottom is hinged to the two telescopic rods 22. This improves the connection stability of the placement sleeve 3, prevents the placement sleeve 3 from deviating from the center of the receiving space in the horizontal direction, and ensures that the two placement sleeves 3 are on the same straight line. This, in turn, ensures the tightness of the placement sleeve 3's fit to the workpiece 6, which is conducive to achieving uniform glue coating on the workpiece 6.

[0048] Specifically, a fixed rod 23 is horizontally positioned at the bottom of the glue gun 2, and shaft holes are provided at both ends of the telescopic rod 22; a connecting post 34 is provided at the bottom of the placement sleeve 3, and the connecting post 34 is parallel to the fixed rod 23; two shaft holes are respectively fitted onto the fixed rod 23 and the connecting post 34. The placement sleeve 3 is hinged to the glue gun 2 through the connecting post 34, the telescopic rod 22, and the fixed rod 23, which improves the connection stability and rotation flexibility of the placement sleeve 3, and has a simple structure, reducing the difficulty of setting up and maintaining the glue application device, while also helping to reduce the production cost of the glue application device and the processing cost of the refrigeration and heating equipment.

[0049] Specifically, the top of the placement sleeve 3 is provided with a fixing rod 23, and the hinge part 21 is rotatably connected to the hinge seat 33 via a pin. Through the hinge structure in which the pin, the hinge seat 33 and the hinge part 21 cooperate with each other, the top of the placement sleeve 3 is hinged to the glue gun 2, so that the top of the placement sleeve 3 can rotate within a certain angle range around the pin, thereby adapting to the shape requirements of the workpiece 6 and ensuring the adhesion and uniformity during the glue application process.

[0050] Specifically, the minimum length of the telescopic rod 22 is greater than or equal to the length of the hinge 21, and the maximum length of the telescopic rod 22 is greater than the length of the hinge 21. The minimum and maximum lengths of the telescopic rod 22 are the lengths of the telescopic rod 22 in its fully retracted and fully extended states, respectively. The telescopic rod 22 can accommodate workpieces 6 of different specifications and sizes. When the diameter of workpiece 6 is slightly less than or equal to the diameter of the receiving space, after workpiece 6 enters the receiving space, the tops and bottoms of the two placement sleeves 3 abut against each other to completely cover the outer circumference of the threaded part of workpiece 6. During the process of workpiece 6 entering the receiving space, the glue gun 2 is pressed, causing the pushing assembly 5 to compress the air in the delivery tube 4, so as to squeeze out the sealant and spread it on the side wall of the placement sleeve 3. Therefore, uniform glue application to workpiece 6 can be achieved without rotating workpiece 6. When the diameter of the threaded part of workpiece 6 is greater than the diameter of the receiving space, workpiece 6 enters the receiving space and squeezes the telescopic rod 22, causing the telescopic rod 22 to retract. At this time, the tops and bottoms of the two placement sleeves 3 are separated from each other. Rotating workpiece 6 so that the outer circumference of workpiece 6 has contacted the placement sleeve 3 can complete the uniform glue application to workpiece 6. The operation is simple and greatly reduces the burden on the workers. Workers do not need to hold the glue gun 2 for a long time and rotate workpiece 6 360°, which improves the glue application efficiency of workpiece 6. At the same time, it expands the application range of the glue application device, which can perform glue application operations on workpieces 6 of different specifications and sizes, and improves the practicality and versatility of the glue application device.

[0051] It is understood that in other embodiments, the hinge seat 33 can be disposed on the glue gun 2 and the corresponding hinge part 21 can be disposed on the placement sleeve 3, depending on actual needs.

[0052] Specifically, the glue inlet 31 is located between the hinge seat 33 and the connecting post 34, and the glue inlet 31 is connected to the glue gun 2 via a flexible hose. The flexible hose, positioned between the hinge seat 33 and the connecting post 34 of the placement sleeve 3, avoids interference between the hose and the hinge structure, ensuring the rotational flexibility of the placement sleeve 3. The flexible hose adapts to the rotation of the placement sleeve 3, reducing the risk of breakage of the connection between the glue inlet 31 and the glue gun 2 during angle adjustment of the placement sleeve 3, maintaining a stable connection between the glue inlet 31 and the glue gun 2, and ensuring the reliability and durability of the glue application device.

[0053] Specifically, the pressing assembly 5 includes a pressure rod 51 and a piston 52. The piston 52 is located inside the delivery pipe 4. One end of the pressure rod 51 is connected to the bottom of the glue gun 2, and the other end is hinged to the piston 52. When the workpiece 6 enters the receiving space, it presses against the placement sleeve 3, causing the glue gun 2 to be compressed and the pressure rod 51 to move downward. The downward movement of the pressure rod 51 causes the piston 52 to move closer to the end of the glue gun 2 inside the delivery pipe 4, thereby compressing the air inside the delivery pipe 4 and the glue gun 2, so that the sealant inside the glue gun 2 is squeezed out onto the placement sleeve 3. The pressing assembly 5 has a simple structure. By pressing the pressing assembly 5 down on the workpiece 6 and squeezing out the sealant by increasing the internal pressure of the glue gun 2, it does not require a power device. It is green, environmentally friendly, and cost-effective, greatly improving the economy and practicality of the glue application device. The glue application device is a purely mechanical structure, which has a lower failure rate and is easier to maintain compared to electronic or pneumatic devices, further improving the stability and durability of the glue application device.

[0054] Specifically, the pressing assembly 5 also includes a connecting rod 53; one end of the connecting rod 53 is hinged to the end of the pressure rod 51 away from the glue gun 2, and the other end is hinged to the piston 52. When the pressing assembly 5 is pressed, the pressure rod 51 moves, causing the connecting rod 53 to move, and the moving connecting rod 53 causes the piston 52 to move. The setting of the connecting rod 53 helps to change the pressing direction of the pressing assembly 5, making it easy to change the pressing direction from the vertical direction to the horizontal or inclined direction, which helps to flexibly adapt to the installation position of the delivery pipe 4, and facilitates the horizontal setting of the piston 52 to reduce the transmission path of the delivery pipe 4, thereby increasing the pushing force given to the glue gun 2 by the pressing assembly 5, which helps to improve the glue dispensing efficiency of the glue gun 2.

[0055] Specifically, a return spring 54 is provided on the outer sleeve of the pressure rod 51. When the pressure rod 51 is pressed down, one end of the return spring 54 abuts against the bottom of the glue gun 2, and the other end abuts against the outer wall of the delivery pipe 4. After the workpiece 6 leaves the receiving space, the return spring 54, through the force of restoring its own elasticity, lifts the glue gun 2 from the bottom, causing the glue gun 2 to return to its original position. The return of the glue gun 2 causes the pressure rod 51 to rise, which in turn causes the connecting rod 53 to move, so that the piston 52 moves away from the end of the delivery pipe 4 away from the glue gun 2, causing the air pressure in the glue gun 2 to recover and stop dispensing glue.

[0056] Specifically, the delivery pipe 4 includes a compression pipe 41 and a connecting hose 42; the pressing assembly 5 is movably connected inside the compression pipe 41, and the two ends of the connecting hose 42 are respectively connected to the output end of the compression pipe 41 and the end of the glue gun 2 away from the placement sleeve 3. The compression pipe 41 is installed on the mounting base 1 to facilitate the movement of the piston 52, so as to fit against the outer wall of the piston 52 and form a relatively closed compression space with the piston 52, thereby improving the compression efficiency and glue dispensing efficiency. The connecting hose 42 is flexible and can flexibly adapt to the angle changes of the glue gun 2, ensuring that the glue gun 2 can maintain a stable connection with the compression pipe 41 in the pressing state or during movement, reducing the failure rate of the glue application device and improving the durability and reliability of the glue application device.

[0057] Specifically, the compression tube 41 is housed within the mounting base 1. More specifically, a mounting groove is provided on the side wall of the mounting base 1 near the placement sleeve 3, and the compression tube 41 is housed within the mounting groove. The placement of the compression tube 41 within the mounting base 1 reduces the exposed structure of the adhesive applicator, effectively protecting the compression tube 41 from external environmental interference and damage. For example, it increases the difficulty for impurities such as dust and moisture to enter the compression tube 41, thereby extending its service life and significantly reducing the frequency of maintenance and repairs of the adhesive applicator. Simultaneously, the mounting groove provides a stable support for the compression tube 41, ensuring its stability during the movement of the working piston 52. This, in turn, ensures the smooth operation of the glue gun 2's pressurization function, preventing glue dispensing interruptions due to shaking or displacement, guaranteeing the reliability of the glue gun 2's dispensing, and thus ensuring the glue coverage rate of the workpiece 6. Furthermore, embedding the compression tube 41 within the mounting base 1 makes the entire adhesive applicator structure more compact and streamlined, and also helps reduce the size of the adhesive applicator, facilitating its carrying and transportation.

[0058] It is understood that, in other embodiments, the compression tube 41 may be fixedly connected to the outer wall of the mounting base 1 so as to facilitate the observation of the usage status of the compression tube 41 and to facilitate timely replacement or repair of the compression tube 41 with high wear or damage.

[0059] Specifically, the compression tube 41 is horizontally positioned. This horizontal positioning helps prevent the pressure rod 51 from impacting the compression rod, ensuring the service life of the pushing assembly 5 and the glue applicator. It also makes the pushing direction more controllable and reduces the distance between the output end of the compression tube 41 and the glue gun 2, thereby reducing the transmission path of the connecting hose 42 and increasing the pushing force provided by the pushing assembly 5 to the glue gun 2, thus improving the glue dispensing efficiency of the glue gun 2.

[0060] Specifically, the glue gun 2 has a glue storage chamber 24 for storing glue; the glue storage chamber 24 is connected to the connecting hose 42 and the glue inlet 31; the connecting hose 42 is connected to the top of the glue gun 2. The connecting hose 42 is located at the top of the glue gun 2 to prevent glue from entering the compression tube 41 from the connecting hose 42 and affecting the movement of the piston 52.

[0061] Specifically, the glue gun 2 has a glue inlet at the end away from the placement sleeve 3, and the glue inlet is equipped with a cap 25. The cap 25 and the glue inlet help to improve the convenience of adding sealant to the glue gun 2 and help to adjust the amount of sealant in the glue storage chamber 24 so that the glue gun 2 can continuously dispense glue when the workpiece 6 presses down on the placement sleeve 3, so as to ensure the smooth progress of the glue application work.

[0062] This embodiment provides an adhesive application device. By setting up a delivery pipe and a pushing component, when the workpiece comes into contact with the placement sleeve, the glue gun is pressed down, thereby driving the pushing component to push the air in the delivery pipe, so as to squeeze the glue in the glue gun onto the placement sleeve. By manually or mechanically rotating the workpiece, or by pressing the workpiece down into the placement sleeve until it is completely wrapped by the two placement sleeves, the workpiece can be glued from all directions, ensuring the coverage and uniformity of the sealant on the workpiece, which helps to improve the tightness of the connection between the workpiece and the connecting parts, thereby improving the quality of the equipment and the safety of operation.
