Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, specifically to an adhesive filling device for adhesive production. Background Technology

[0002] The glue filling equipment used in the production of water-based adhesives is an automated or semi-automated mechanical device specifically designed to accurately and efficiently inject the produced adhesive into packaging containers. Its core function is to solve the problems of low efficiency, poor accuracy, and easy contamination caused by manual filling due to the high viscosity, easy sedimentation, easy curing, and corrosiveness of adhesives. At the same time, it ensures the sealing, safety, and consistency of the production process. It is the core equipment in the filling and packaging stage of large-scale adhesive production.

[0003] However, in current mainstream glue filling equipment, the connection between the filling head and the glue inlet tube generally adopts a multi-bolt threaded fastening structure. Since the filling head is the core component that directly contacts the glue during glue production, it needs to be replaced depending on the glue type. Frequent disassembly, cleaning, and replacement are also necessary due to glue residue drying and reducing filling accuracy. However, the multi-bolt threaded structure limits the complexity of each maintenance operation. Operators must use wrenches and other tools to loosen all bolts one by one in a diagonal sequence. After cleaning or replacing the filling head, reinstallation requires aligning each bolt with the threaded hole and tightening it again, strictly controlling the tightening torque of each bolt to avoid uneven torque leading to poor sealing. This entire maintenance process is time-consuming, significantly reducing production time, increasing operator workload, and shortening the effective operating time of the equipment. Therefore, we propose a glue filling equipment for glue production. Summary of the Invention

[0004] The purpose of this utility model is to provide an adhesive filling equipment for adhesive production, so as to solve the problem mentioned in the background art that the entire maintenance process is time-consuming, which not only greatly occupies production time, but also increases the labor intensity of operators, and also leads to a reduction in the effective operating time of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glue filling equipment for glue production, comprising a filling machine body, an inlet pipe inside the filling machine body, a quick-connect assembly at the bottom of the inlet pipe, and a double-sealing assembly at the bottom of the quick-connect assembly. The quick-connect assembly enables quick assembly and fixation between the inlet pipe and the double-sealing assembly, and the double-sealing assembly seals the filling process and monitors glue leakage.

[0006] The quick-connect assembly includes a glue inlet connector, which is fixedly installed at the bottom of the glue inlet tube. A fixing bracket is fixedly installed on the outside of the glue inlet connector. A fixing shaft is fixedly installed on one side of the fixing bracket. An L-shaped bracket is rotatably connected to the outside of the fixing shaft. An inverted L-shaped bracket is fixedly installed on the top of the L-shaped bracket. Buffer pads are fixedly installed on the top of the protruding part of the L-shaped bracket and the bottom of the protruding part of the inverted L-shaped bracket.

[0007] The protruding part of the fixing frame is slidably connected to the protruding part of the inverted L-shaped bracket through a sliding groove inside it. A rubber pad is fixedly installed on the side of the protruding part of the L-shaped bracket, and a protruding frame is fixedly installed on the other side of the protruding part of the L-shaped bracket. A spring key is provided on the side of the protruding frame, and a mounting bracket is provided at the bottom of the fixing frame.

[0008] The mounting bracket is slidably connected to the rubber pad through an internal groove. The protruding bracket passes through the mounting bracket, and part of the protruding bracket and the spring key are located on the outside of the mounting bracket. The inside of the mounting bracket is slidably connected to the protruding part of the L-shaped bracket. The fixed bracket, mounting bracket, fixed shaft, L-shaped bracket, inverted L-shaped bracket, buffer pad, rubber pad, spring key and protruding bracket are all provided on the outside of the glue inlet joint in twos.

[0009] The dual sealing assembly includes a guide frame, an inlet connector that is slidably connected to the guide frame through a groove inside the guide frame, multiple ball spring pins inside the guide frame, an inlet connector that is slidably connected to the ball spring pins through a through hole inside the guide frame, an inlet head that is fixedly installed at the bottom of the guide frame, and an mounting bracket that is fixedly installed on the outside of the inlet head.

[0010] The dispensing head has a transparent window on its exterior, a first sealing ring is fixedly installed on the top of the dispensing head, and a second sealing ring is fixedly installed on the top of the dispensing head. The diameter of the second sealing ring is larger than that of the first sealing ring. A leakage groove is provided on the top of the dispensing head, which is located between the second sealing ring and the first sealing ring. The transparent window allows observation of the leakage groove.

[0011] This utility model has at least the following beneficial effects:

[0012] The quick-connect assembly, with its bidirectional guiding L-shaped and inverted L-shaped brackets, prevents component misalignment during connection. Buffer pads reduce component impact and wear, extending assembly lifespan and initially enhancing connection stability. The tight fit between the rubber pad and the mounting bracket's groove, along with the locking action of the spring key, further improves connection strength, preventing loosening during use. The dual-seal assembly utilizes a double-seal structure: the first sealing ring acts as a primary seal, directly preventing adhesive leakage from the core contact surface, while the second sealing ring acts as a secondary seal, intercepting any small amount of adhesive that breaches the primary seal. This dual protection significantly reduces the probability of adhesive leakage, ensuring a clean dispensing environment and preventing adhesive waste. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: an adhesive filling equipment for adhesive production, including a filling machine body 1, an adhesive inlet pipe 2 is provided inside the filling machine body 1, a quick connection component 3 is provided at the bottom of the adhesive inlet pipe 2, and a double sealing component 4 is provided at the bottom of the quick connection component 3. The quick connection component 3 is used to quickly assemble and fix the adhesive inlet pipe 2 and the double sealing component 4, and the double sealing component 4 is used to seal the filling process and monitor adhesive leakage.

[0021] The quick-connect assembly 3 includes a glue inlet connector 31, which is fixedly installed at the bottom of the glue inlet tube 2. A fixing bracket 32 ​​is fixedly installed on the outside of the glue inlet connector 31. A fixing shaft 34 is fixedly installed on one side of the fixing bracket 32. An L-shaped bracket 35 is rotatably connected to the outside of the fixing shaft 34. An inverted L-shaped bracket 36 is fixedly installed on the top of the L-shaped bracket 35. Buffer pads 37 are fixedly installed on the top of the protruding part of the L-shaped bracket 35 and the bottom of the protruding part of the inverted L-shaped bracket 36. The protruding part of the fixing bracket 32 ​​is slidably connected to the protruding part of the inverted L-shaped bracket 36 through a sliding groove provided inside. A rubber pad 38 is fixedly installed on the side of the protruding part of the L-shaped bracket 35. A protruding bracket 310 is fixedly installed on the other side of the protruding part of the L-shaped bracket 35. A spring key 39 is provided on the side of the protruding bracket 310. A mounting bracket 33 is provided at the bottom of the fixing bracket 32. The mounting bracket 33 is connected to the rubber pad through a sliding groove provided inside. The 38 sliding connection has a protruding bracket 310 penetrating the mounting bracket 33. A portion of the protruding bracket 310 and the spring key 39 are located outside the mounting bracket 33. The interior of the mounting bracket 33 is slidably connected to the protruding portion of the L-shaped bracket 35. Two of the following components are located outside the glue inlet connector 31: the fixed bracket 32, mounting bracket 33, fixed shaft 34, L-shaped bracket 35, inverted L-shaped bracket 36, buffer pad 37, rubber pad 38, spring key 39, and protruding bracket 310. The core objective is to achieve a precise and stable connection between the glue inlet tube 2 and the glue dispensing head 41. Initial positioning is achieved by first aligning and sliding the guide bracket 43 with the glue inlet connector 31, and then embedding the ball spring pin 44 into the through hole. Next, the L-shaped bracket 35 and the inverted L-shaped bracket 36 engage bidirectionally, with the buffer pad 37 reducing wear and the rubber pad 38 enhancing stability. Finally, the spring key 39 pops out for locking, and the symmetrically arranged fixed bracket 32 ​​and mounting bracket 33 ensure coaxiality, ultimately achieving a precise connection without any loosening.

[0022] The double sealing assembly 4 includes a guide frame 43, an inlet connector 31 which is slidably connected to the guide frame 43 via an internal groove, a plurality of ball spring pins 44 which are internally arranged in the guide frame 43, and the inlet connector 31 which is slidably connected to the ball spring pins 44 via internal through holes, a dispensing head 41 which is fixedly mounted at the bottom of the guide frame 43, a mounting bracket 33 which is fixedly mounted on the outside of the dispensing head 41, a transparent window 42 which is provided on the outside of the dispensing head 41, a first sealing ring 45 which is fixedly mounted on the top of the dispensing head 41, and a second sealing ring 46 which is fixedly mounted on the top of the dispensing head 41, the diameter of the second sealing ring 46 being larger than that of the first sealing ring 45. The dispensing head 41 has a diameter of 5 mm and a leakage groove 47 is provided on its top. The leakage groove 47 is located between the second sealing ring 46 and the first sealing ring 45. The transparent window 42 allows observation of the leakage groove 47. With leakage prevention and timely monitoring as the core, after quick connection, the first sealing ring 45 forms a primary seal and the second sealing ring 46 forms a secondary seal to prevent glue leakage. If the first sealing ring 45 fails, the leaked glue will flow into the leakage groove 47 located between the two sealing rings. The operator can observe in real time through the transparent window 42 corresponding to the leakage groove 47, promptly detect and deal with sealing problems, and avoid the leakage from expanding and causing losses.

[0023] During initial assembly, the connection between the glue inlet tube 2 and the glue dispensing head 41 must be completed first. This process is led by the quick-connect assembly 3. The guide frame 43 on the top of the glue dispensing head 41 is first aligned with the bottom of the glue inlet connector 31. The glue inlet connector 31 slides with the guide frame 43 through the internal groove. At the same time, multiple ball spring pins 44 inside the guide frame 43 will be embedded in the through hole of the glue inlet connector 31 to achieve precise positioning of the glue inlet connector 31 and the glue dispensing head 41, ensuring that the subsequent connection sealing structure is completely fitted. Since the glue inlet connector 31 is fixed at the bottom of the glue inlet tube 2, and the mounting bracket 33 is fixed outside the glue dispensing head 41, it is necessary to ensure that the groove of the mounting bracket 33 is aligned with the protruding part of the L-shaped bracket 35 on one side of the fixed bracket 32. Then, manually push the L-shaped bracket 35 to rotate around the fixed shaft 34, so that the protruding part of the L-shaped bracket 35 is inserted into the internal groove of the mounting bracket 33. At the same time, the inverted L-shaped bracket 36 fixed to the top of the L-shaped bracket 35 will move synchronously with the L-shaped bracket 35, and its protruding part moves along the fixed shaft 34. The internal sliding groove of the protruding part of the fixed bracket 32 ​​slides, forming a two-way guide to prevent the L-shaped bracket 35 from shifting. Due to the buffer pad 37 at the top of the protruding part of the L-shaped bracket 35 and the bottom of the protruding part of the inverted L-shaped bracket 36, it will fit against the contact surface of the mounting bracket 33 and the fixed bracket 32 ​​during the locking process, which reduces the collision and wear of the components and initially enhances the stability after connection. At the same time, the rubber pad 38 on the side of the L-shaped bracket 35 slides tightly with the sliding groove of the mounting bracket 33, further improving the connection stability. When the L-shaped bracket 35 is fully locked in place, the protruding bracket 310 will pass through the mounting bracket 33 and extend to the outside. At this time, the spring key 39 on the side of the protruding bracket 310 will automatically pop out and lock on the outer wall of the mounting bracket 33, realizing the locking of the L-shaped bracket 35 and the mounting bracket 33. Since the fixed bracket 32, the mounting bracket 33 and other components are symmetrically arranged on the outside of the glue inlet joint 31, the coaxiality of the glue inlet joint 31 and the glue dispensing head 41 can be ensured after the two sides are locked simultaneously, thus preventing the connection from loosening.

[0024] After the quick connection is completed, the equipment enters the glue dispensing preparation state. The dispensing speed of the dispensing head 41 needs to be coordinated with the operating speed of the finished product conveying drive system to avoid glue overflow due to untimely delivery of finished products caused by excessively fast dispensing speed, or waste of energy due to idling of the finished product conveying drive system caused by excessively slow dispensing speed. The first sealing ring 45 and the second sealing ring 46 fixed on the top of the dispensing head 41 will fit tightly against the bottom end face of the glue inlet connector 31 as the guide frame 43 aligns with the glue inlet connector 31. The smaller diameter first sealing ring 45 directly contacts the periphery of the glue outlet of the glue inlet connector 31, forming a primary seal to prevent glue from leaking outward from the core contact surface between the glue outlet and the dispensing head 41. The larger diameter second sealing ring 46 forms a secondary seal outside the first sealing ring 45. Even if a small amount of glue breaks through the primary seal, it will be blocked by the secondary seal, forming double protection. Since the leakage groove 47 on the top of the dispensing head 41 is located between the first sealing ring 45 and the second sealing ring 46, if the first sealing ring 45 fails to seal, a small amount of glue will leak out. Leaked glue will flow into the leakage tank 47 due to gravity, rather than dripping directly onto the external environment or product. The transparent window 42 on the outside of the dispensing head 41 corresponds to the position of the leakage tank 47. The operator can observe the internal status of the leakage tank 47 in real time through the transparent window 42. If there is no glue accumulation in the leakage tank 47, it indicates that the double seal is normal. If glue is observed in the leakage tank 47, it can be immediately determined that there is a leakage problem with the first sealing ring 45. The machine needs to be stopped for inspection or the sealing ring needs to be replaced to avoid the leakage from expanding and causing product scrapping or equipment contamination. When adjusting the dispensing speed of the dispensing head 41, the sealing fit of the first sealing ring 45 and the second sealing ring 46 should be checked simultaneously to ensure that the double sealing structure can still fit tightly against the bottom end face of the glue inlet connector 31 at different dispensing speeds, effectively blocking glue leakage. At the same time, the finished product conveying drive system needs to be adapted to the corresponding parameters according to the dispensing speed adjusted by the dispensing head 41 to avoid subsequent finished product accumulation or excessive conveying gap due to speed mismatch, and further maintain the overall coordination of equipment operation.
