Description

Technical Field

[0001] This utility model relates to the field of filling devices, specifically an automatic quantitative filling device for industrial glue. Background Technology

[0002] Industrial glue quantitative filling devices achieve high-precision filling through PLC control and a weighing or metering valve feedback system. They support multi-speed adjustment to adapt to glues of different viscosities and have anti-drip, barrel collision protection, and automatic tare functions. The equipment has a wide capacity range, and the filling speed varies depending on the capacity. The materials are mostly stainless steel and PTFE sealing for corrosion resistance. Some models support explosion-proof and nitrogen-filling options and are suitable for chemical, food and other industries.

[0003] Current glue filling devices typically use metering valves to dispense a fixed amount of glue into the bottle. However, a problem exists in actual operation: after the glue is dispensed, the throttle valve closes the passage, leaving a small amount of residual glue dripping from the dispensing gun port. In traditional solutions, when the dispensing gun retracts, an electric actuator immediately pushes a receiving plate to catch the small amount of glue that may fall. This solution involves additional electrical components and requires precise logic coordination, which undoubtedly increases the cost of the filling device and poses certain safety risks. Therefore, the inventors urgently need to design a glue receiving mechanism to reduce the use of the actuator in traditional solutions and improve the ease of use of the filling device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automatic quantitative filling device for industrial adhesives, so as to solve the technical problem that the use of electric push rods in traditional receiving mechanisms leads to complex control logic and increased device cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic quantitative filling device for industrial adhesive, comprising a conveyor belt, a bottle, a support rod, and a filling assembly. The support rod is fixed above a support table. The filling assembly includes an electric push rod and several filling guns. The electric push rod is installed at the top of the support rod. A receiving mechanism is provided on one side of each filling gun. The receiving mechanism includes a receiving box. A movable plate is fixedly provided on one side of the receiving box, and the movable plate is rotatably connected to one side of the filling gun via a rotating shaft. A connecting rod is hinged between one side of the movable plate and the electric push rod mounting plate.

[0006] By adopting the above technical solution, the filling component and the receiving mechanism are integrated on the support rod to form a compact mechanical linkage structure. The electric actuator serves as the sole power source, simultaneously controlling the lifting and lowering of the filling gun and the swinging of the receiving box, which significantly simplifies the complex structure of the traditional design that requires an independently driven anti-drip device.

[0007] Furthermore, the connecting rod includes a first connecting rod and a second connecting rod, and an adjusting sleeve is threadedly connected between the first connecting rod and the second connecting rod for adjusting the length of the connecting rod.

[0008] By adopting the above technical solution, using a first connecting rod and a second connecting rod and achieving a threaded connection through an adjusting sleeve, the length of the connecting rod is precisely adjustable, allowing operators to flexibly adjust it according to the actual height of the filling head, the position of the bottle mouth, and the optimal swing trajectory required by the receiving box, greatly enhancing the equipment's adaptability to bottles of different sizes.

[0009] Furthermore, the cross-section of the receiving box and the movable plate is Z-shaped, and the top surface of the receiving box has several openings, which are opposite to the longitudinal position of the injection head of the injection gun.

[0010] By adopting the above technical solution, the receiving box and the movable plate adopt a "Z" shaped cross-section structure, which achieves the maximum structural strength and functional integration in a limited space. The "Z" shaped bend provides the necessary rigidity to ensure that it is not easily deformed during frequent swings. At the same time, its shape allows the receiving box to effectively avoid the descending filling gun and bottle, and the movement path is more reasonable.

[0011] Furthermore, the receiving box has an interior cavity, and the bottom of the interior cavity is filled with a sponge for securing the adhesive.

[0012] By adopting the above technical solution, the bottom of the cavity inside the receiving box is filled with sponge material. Utilizing the porous adsorption properties of the sponge, it can quickly absorb and contain the dripping liquid adhesive, preventing it from shaking or splashing out of the box due to its fluidity, thus achieving instant curing and stabilization of the dripping adhesive.

[0013] Furthermore, the telescopic end of the electric actuator is equipped with a movable frame, which is detachably connected to several injection guns.

[0014] By adopting the above technical solution, a movable frame is installed at the telescopic end of the electric push rod, and several filling guns are detachably connected to it, thus constructing a modular filling head assembly. This allows for the quick installation or replacement of different numbers and specifications of filling guns as needed, enabling the equipment to flexibly adapt to the filling needs of single-row, multi-row, or different-spacing bottles, greatly improving the flexibility of the production line.

[0015] Furthermore, a proximity sensor is installed on one side of the conveyor belt. The proximity sensor is used to detect the number of bottles transported by the conveyor belt. The model of the proximity sensor is GHRA-F23K.

[0016] By adopting the above technical solution, the sensor can reliably detect bottles and achieve non-contact counting of bottles passing through them. This counting method is not affected by ambient light, dust or bottle color, has high stability, and provides the system with accurate bottle flow data.

[0017] Furthermore, a servo motor is also installed on one side of the conveyor belt, and a baffle plate for intercepting the bottle is installed at the output end of the servo motor.

[0018] By adopting the above technical solution and using a servo motor to drive the blocking plate, extremely high-precision angle and position control can be achieved. After receiving the signal from the proximity sensor, the servo system can quickly drive the blocking plate to rotate to a precise angle and intercept the bottle at the predetermined station.

[0019] Furthermore, a liquid level sensor for detecting the level of adhesive inside the bottle is installed on one side of the servo motor. The model of the liquid level sensor is DEUZE PA28 series.

[0020] By adopting the above technical solution, a DEUZE PA28 series liquid level sensor is added to the filling station. This photoelectric sensor can perform non-contact detection of the glue level in the bottle. The detection result serves as an important basis for judging whether the filling amount is qualified. The data is transmitted to the control system in real time to participate in quality judgment and statistics, realizing the post-event monitoring and closed-loop feedback of filling accuracy.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model uses a receiving mechanism and an electric actuator as a single power source to simultaneously drive the lifting and lowering of the filling gun and the swinging of the receiving mechanism, eliminating the need for an independent electric actuator in traditional solutions. Its direct effect is to reduce hardware costs and simplify control logic, avoiding timing errors in the coordination of multiple actuators. At the same time, the receiving box is rigidly connected to the electric actuator through a movable plate and a connecting rod, ensuring that the receiving box can instantly return to the position directly below the nozzle when the filling head rises. This purely mechanical synchronization mechanism completely solves the problem of glue contamination caused by control delay.

[0023] 2. This utility model uses a liquid level sensor to detect the filling result and transmit the detection data to the controller. The quality of the glue inside the bottle is calculated based on the liquid level height, and the pass rate is calculated, thereby further improving the filling quality of the glue in the bottle.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In this embodiment:

[0032] An automatic quantitative filling device for industrial adhesives, such as Figure 1-5As shown, the assembly includes a conveyor belt 2, a bottle body 4, a support rod 5, and a filling component 6. The support rod 5 is fixed above the support table 1. The filling component 6 includes an electric push rod 601 and several filling guns 603. The electric push rod 601 is installed at the top of the support rod 5. A receiving mechanism 7 is provided on one side of each filling gun 603. The receiving mechanism 7 includes a receiving box 701. A movable plate 702 is fixedly installed on one side of the receiving box 701, and the movable plate 702 is rotatably connected to one side of the filling gun 603 via a rotating shaft. A connecting rod is hinged between one side of the movable plate 702 and the fixed mounting plate of the electric push rod 601. By integrating the filling component 6 and the receiving mechanism 7 into the support rod... 5. A compact mechanical linkage structure is formed, with the electric actuator 601 serving as the sole power source, simultaneously controlling the lifting and lowering of the filling gun 603 and the swinging of the receiving box 701. This significantly simplifies the complex structure of the anti-drip device that requires independent driving in traditional designs. Meanwhile, the movable plate 702 is connected to the filling gun 603 via a rotating shaft and hinged to the fixed plate of the electric actuator 601 via a connecting rod, so that the movement of the receiving mechanism is naturally synchronized with the filling action. This purely mechanical linkage method not only reduces the risk of receiving failure due to electrical signal delay or logic error, but also reduces the use of additional sensors and control components, thereby improving system reliability and economy.

[0033] See Figure 3 , Figure 4 , Figure 5 The connecting rod includes a first connecting rod 703 and a second connecting rod 704. An adjusting sleeve 705 is threadedly connected between the first connecting rod 703 and the second connecting rod 704 for adjusting the length of the connecting rod. The use of the first connecting rod 703 and the second connecting rod 704 and the threaded connection through the adjusting sleeve 705 provides a fine adjustment capability for the length of the connecting rod. This allows the operator to flexibly adjust the length according to the actual height of the filling head, the position of the bottle mouth, and the optimal swing trajectory required by the receiving box 701. This greatly enhances the adaptability of the equipment to bottles of different sizes. At the same time, the threaded structure of the adjusting sleeve 705 has a self-locking characteristic, which can maintain the length stability in a vibration environment and ensure the repeatability accuracy of the motion parameters of the receiving mechanism 7.

[0034] See Figure 3 , Figure 4 , Figure 5The receiving box 701 and the movable plate 702 have a "Z" shaped cross-section. The top surface of the receiving box 701 has several openings 706, which are longitudinally opposite to the filling head of the filling gun 603. The receiving box 701 and the movable plate 702 adopt a "Z" shaped cross-section structure, which achieves maximum structural strength and functional integration in a limited space. The "Z" shaped bend provides the necessary rigidity to ensure that it is not easily deformed during frequent swinging. At the same time, its shape allows the receiving box to effectively avoid the descending filling gun 603 and bottle 4, making the movement path more reasonable. Meanwhile, the several openings 706 on the top surface of the receiving box 701 are precisely aligned longitudinally with the filling head of the filling gun 603, ensuring that the residual glue dripping from the gun head during the rising process can fall into the openings without deviation and be directly received by the receiving box cavity below.

[0035] See Figure 3 , Figure 4 , Figure 5 The receiving box 701 has an internal cavity, and the bottom of the cavity is filled with a sponge for stabilizing the adhesive. The sponge material fills the bottom of the cavity inside the receiving box 701. Utilizing the porous adsorption properties of the sponge, it can quickly absorb and contain the dripping liquid adhesive, preventing it from shaking or splashing out of the box due to its fluidity. This achieves instant curing and stabilization of the dripping adhesive. At the same time, the sponge, as a soft and low-cost consumable material, is easy to replace and clean regularly, effectively avoiding cross-contamination.

[0036] See Figure 1 , Figure 2 The telescopic end of the electric push rod 601 is equipped with a movable frame 602, which is detachably connected to several filling guns 603. By installing the movable frame 602 on the telescopic end of the electric push rod 601 and detachably connecting several filling guns 603 to it, a modular filling head assembly is constructed. This allows for the quick installation or replacement of different numbers and specifications of filling guns as needed, enabling the equipment to flexibly adapt to the filling requirements of single-row, multi-row, or bottles with different spacing, greatly improving the flexibility of the production line. At the same time, the movable frame 602 ensures that all filling guns 603 maintain synchronous lifting and lowering motion under the drive of the electric push rod 601, with consistent filling depth, thereby ensuring the consistency of the filling volume of each bottle.

[0037] See Figure 1 , Figure 2A proximity sensor 301 is installed on one side of the conveyor belt 2. The proximity sensor 301 is used to detect the number of bottles 4 transported by the conveyor belt 2. The model of the proximity sensor 301 is GHRA-F23K. This sensor can reliably detect bottles 4 and realize non-contact counting of the bottles passing through. This counting method is not affected by ambient light, dust or bottle color, and has high stability. It provides the system with accurate bottle flow data. At the same time, the counting signal is the basis for triggering the subsequent filling and positioning process, ensuring that the filling component 6 only starts working after the bottle is accurately in place, avoiding empty filling or malfunction. It is a key link in realizing fully automatic cycle control and ensures the orderly production cycle.

[0038] See Figure 1 , Figure 2 A servo motor 302 is also installed on one side of the conveyor belt 2. A baffle plate 303 for intercepting the bottle 4 is installed at the output end of the servo motor 302. The setting of using the servo motor 302 to drive the baffle plate 303 can achieve extremely high-precision angle and position control. After receiving the signal from the proximity sensor 301, the servo system can quickly drive the baffle plate 303 to rotate to a precise angle to intercept the bottle 4 at the predetermined station. At the same time, the running speed and torque of the servo motor 302 can be flexibly programmed, which can achieve both rapid response to match the speed of the conveyor belt 2 and smooth start and stop control, avoiding violent impact on the bottle and causing it to tip over or be damaged, thus ensuring the smoothness and efficiency of the production process.

[0039] See Figure 1 , Figure 2 A level sensor 304 is installed on one side of the servo motor 302 to detect the glue level inside the bottle 4. The level sensor 304 is a DEUZE PA28 series sensor. The addition of a DEUZE PA28 series level sensor 304 at the filling station allows for non-contact detection of the glue level inside the bottle. The detection result serves as an important basis for judging whether the filling quantity is qualified. This data is transmitted to the control system in real time to participate in quality judgment and statistics, realizing post-event monitoring and closed-loop feedback of filling accuracy. At the same time, the level detection function can also serve as a safety redundancy barrier, promptly detecting and rejecting unqualified products when there is a slight deviation in the metering valve, or triggering an alarm to prompt maintenance personnel to adjust the filling parameters, thereby continuously improving the consistency and reliability of the overall filling quality.

[0040] The implementation principle of this embodiment is as follows: the conveyor belt 2 continuously transports the bottle 4. When the proximity sensor 301 detects that the bottle has arrived at the filling station, the servo motor 302 drives the baffle plate 303 to rotate to accurately position the bottle. Subsequently, the electric push rod 601 of the filling assembly 6 pushes the movable frame 602 and the filling gun 603 to descend, so that the end of the filling gun extends into the bottle mouth for quantitative filling. During this process, the descent of the electric push rod 601 drives the movable plate 702 of the receiving mechanism 7 to rotate around the pivot through the connecting rod, so that the receiving box 701 swings outward synchronously to avoid the obstruction. After filling is completed, the electric push rod 601 rises back, and the filling gun 603 rises accordingly. The reverse movement of the connecting rod drives the movable plate 702 to rotate, quickly resetting the receiving box 701 to directly below the port of the filling gun 603 to catch any dripping residual glue. The sponge inside the box can absorb the glue. At the same time, the baffle plate 303 rotates to one side, and the filled bottle 4 continues to be transported by the conveyor belt 2. Subsequently, the liquid level sensor 304 detects the filling result and transmits the detection data to the controller. The quality of the glue inside the bottle 4 is calculated based on the liquid level height, and the pass rate is calculated to further improve the filling quality of the glue in the bottle 4. The filled bottle is transported out by the conveyor belt 2, and the system enters the next working cycle.
