Description

Technical Field

[0001] This utility model belongs to the field of adhesive production technology, specifically relating to an adhesive quantitative filling machine for adhesive production. Background Technology

[0002] Adhesives are intermediates that connect two materials, often appearing as water-based solutions. They belong to the fine chemical category and are diverse, primarily classified by adhesive type, physical form, curing method, and the materials being bonded. The bonding of objects relies on the tension between the polymer molecules in the adhesive. Water acts as a carrier for these polymer molecules, slowly penetrating the material's structure. Once the water evaporates, the polymer molecules bind the two materials together tightly through mutual tension. During the adhesive processing, filling machines are needed for later packaging. However, existing filling machines are often unsuitable for different sizes of adhesive containers, limiting their applicability and overall limitations.

[0003] A patent with publication number CN214570666U discloses a filling device for flame-retardant adhesives. The device includes can placement slots, a filling workbench, a suction pump, a dispensing pipe, a mixing tank, a guiding pipe, and a dispensing head. In use, the adhesive holding devices are sequentially and fixedly installed inside multiple can placement slots at the top of the filling workbench. The suction pump is activated, drawing uniformly mixed adhesive from the mixing tank through the dispensing pipe and guiding it through the guiding pipe to the dispensing head, thereby delivering it to the holding devices within the can placement slots.

[0004] However, the size of the tank placement slot in the above solution is fixed, making it unsuitable for containers of different sizes, resulting in a limited overall applicability and strong limitations. Furthermore, the above solution cannot promptly replace the container after filling, further increasing the limitations of the device and leading to poor practical performance. Utility Model Content

[0005] To address the problems existing in the background art, this utility model provides a quantitative filling machine for adhesive production.

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

[0007] An adhesive quantitative filling machine for adhesive production includes a worktable, on which a rotating platform is rotatably mounted. A plurality of second gears are rotatably mounted within the rotating platform, arranged in a circular array along the central axis of the rotating platform. A drive mechanism is provided within the rotating platform to drive the plurality of second gears to rotate synchronously. A connecting rod is fixedly mounted on the top of each second gear, and the top of each connecting rod rotatably passes through the top of the worktable and is fixedly mounted on a placement platform. A plurality of limiting plates are slidably mounted on each placement platform, with the limiting plates on the same placement platform moving closer to or further away from the central axis of the placement platform. The placement platform and the limiting plates are in a transmission engagement.

[0008] Furthermore, the driving mechanism includes a second motor, which is fixedly installed inside the rotating platform. The output shaft of the second motor is coaxially and fixedly connected to the first gear. The first gear is coaxially arranged with the rotating platform, and a plurality of second gears mesh with the first gear for transmission.

[0009] Furthermore, the top of the rotating platform is provided with several limiting groove assemblies, the number of which is equal to the number of the placement platform and they correspond one-to-one. Each limiting groove assembly includes several limiting grooves. A limiting block is slidably arranged in each limiting groove, and a limiting rod is fixedly arranged at the bottom of each limiting plate. The number of limiting blocks and limiting rods is equal and they are fixedly connected one-to-one. In addition, several guide grooves are provided on each placement platform, the number of which is equal to the number of limiting rods and they correspond one-to-one. Each limiting rod is slidably arranged in the corresponding guide groove.

[0010] Furthermore, a material box and a fixed frame are fixedly installed on the workbench. A rotating rod is rotatably installed inside the fixed frame, and a lifting plate is slidably installed in a vertical direction. An airbag is fixedly installed on the top of the lifting plate, and the top of the airbag is fixedly connected to the fixed frame. The rotating rod and the lifting plate are in transmission cooperation.

[0011] Furthermore, a second glue delivery tube is provided between the material box and the air bladder, and a first glue delivery tube is fixedly provided on the top of the air bladder. One end of the first glue delivery tube is connected to the inside of the air bladder, and a filling gun is fixedly provided on the other end of the first glue delivery tube. The filling gun is located above the placement platform. Valves are installed inside both the first glue delivery tube and the second glue delivery tube.

[0012] Furthermore, a sliding groove is formed on the outer surface of the rotating rod, and a sliding block is fixedly installed on the lifting plate. The sliding block is limited and slidably installed in the sliding groove. The sliding groove is a periodic arc-shaped groove, which includes two rising arc-shaped grooves and two falling arc-shaped grooves. The rising arc-shaped grooves and falling arc-shaped grooves are arranged alternately and connected end to end.

[0013] Furthermore, a first motor is fixedly installed inside the workbench, and a turntable is fixedly mounted on the output shaft of the first motor. The top of the turntable is coaxially and fixedly connected to the bottom of the rotating rod. Two transmission components are fixedly mounted on the outer surface of the turntable. The two transmission components are symmetrically arranged, and each transmission component contains multiple teeth. A toothed ring is fixedly fitted on the outer arc surface of the rotating table, and both transmission components are engaged with the toothed ring in a contact-type transmission.

[0014] This application has the following beneficial effects:

[0015] 1. The drive mechanism can drive the second gear to rotate, causing the placement platform connected to the second gear to rotate. This causes several limiting plates on the placement platform to move closer to or further away from the central axis of the placement platform, thereby centering and clamping the containers of different sizes. This has a wider range of applications and better practical effects.

[0016] 2. This solution not only enables precise dispensing of adhesives, but also allows for timely replacement of the container after dispensing, further improving the overall practical effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A quantitative filling machine for adhesive production includes a worktable 1, a rotating platform 4 is rotatably arranged inside the worktable 1, and a plurality of second gears 8 are rotatably arranged inside the rotating platform 4. The plurality of second gears 8 are arranged in a circular array along the central axis of the rotating platform 4, and a drive mechanism is provided inside the rotating platform 4 to drive the plurality of second gears 8 to rotate synchronously.

[0027] The drive mechanism includes a second motor 6, which is fixedly installed inside the rotating platform 4. The output shaft of the second motor 6 is coaxially and fixedly connected to a first gear 7. The first gear 7 is coaxially arranged with the rotating platform 4, and several second gears 8 mesh with the first gear 7 for transmission.

[0028] Each second gear 8 has a connecting rod 25 fixedly mounted on its top coaxially. The top of each connecting rod 25 rotatably passes through the rotating platform 4 and is fixedly mounted on a placement platform 9 coaxially. Each placement platform 9 has several limiting plates 14 slidably mounted on its top. The limiting plates 14 are arc-shaped plates, and the limiting plates 14 move closer to or further away from the central axis of the placement platform 9. The limiting plates 14 are in a transmission engagement with the placement platform 9.

[0029] The rotating platform 4 has several limiting groove assemblies on its top, with the number of limiting groove assemblies equal to and corresponding one-to-one with the placement platform 9. Each limiting groove assembly includes several limiting grooves 10. A limiting block 11 is slidably disposed within each limiting groove 10, and a limiting rod 12 is fixedly disposed at the bottom of each limiting plate 14. The number of limiting blocks 11 and limiting rods 12 are equal and fixedly connected one-to-one. In addition, several guide grooves 13 are provided on each placement platform 9. The guide grooves 13 are arc-shaped, and the number of guide grooves 13 is equal to and corresponds one-to-one with the limiting rods 12. Each limiting rod 12 is slidably disposed within its corresponding guide groove 13.

[0030] The rotation of the second gear 8 drives the placement platform 9 to rotate. Under the guidance of the guide groove 13 and the limitation of the limiting groove 10, the limiting plate 14 on the top of the placement platform 9 moves closer to or further away from the central axis of the placement platform 9, thereby centering and clamping the container on the placement platform 9. At the same time, by adjusting the rotation angle of the placement platform 9, it can be adapted to container of different specifications.

[0031] A material box 23 and a fixed frame 24 are fixedly installed on the workbench 1. The fixed frame 24 is T-shaped. Inside the fixed frame 24, a rotating rod 15 is rotatably mounted, and a lifting plate 18 is slidably mounted in a vertical direction. An airbag 20 is fixedly mounted on the top of the lifting plate 18, and the top of the airbag 20 is fixedly connected to the fixed frame 24. The rotating rod 15 and the lifting plate 18 are driven together. By rotating the rotating rod 15, the lifting plate 18 can be driven to slide up and down repeatedly, thereby repeatedly squeezing and stretching the airbag 20.

[0032] The material box 23 is fixedly provided with a second glue delivery pipe 22. The second glue delivery pipe 22 is a telescopic pipe. The bottom opening of the second glue delivery pipe 22 extends into the material box 23 and communicates with the interior of the material box 23. The top opening of the second glue delivery pipe 22 passes through the fixing frame 24 and the lifting plate 18 in sequence and extends into the air bag 20 and communicates with the interior of the air bag 20.

[0033] A first glue delivery tube 21 is fixedly installed on the top of the airbag 20. One end of the first glue delivery tube 21 is connected to the inside of the airbag 20, and a filling gun 19 is fixedly installed on the other end of the first glue delivery tube 21. The filling gun 19 is located above the placement platform 9.

[0034] Both the first glue delivery pipe 21 and the second glue delivery pipe 22 are equipped with valves (not shown in the figure). The valve in the first glue delivery pipe 21 is used to prevent the adhesive in the first glue delivery pipe 21 from flowing back into the airbag 20, and the valve in the second glue delivery pipe 22 is used to prevent the adhesive in the airbag 20 from flowing back into the material box 23, thereby realizing the discharge and delivery of the airbag 20.

[0035] The outer surface of the rotating rod 15 has a groove 16, and a sliding block 17 is fixedly installed on the lifting plate 18. The sliding block 17 is limited and slidably installed in the groove 16.

[0036] The slide 16 is a periodic arc-shaped groove, including two rising arc-shaped grooves and two falling arc-shaped grooves. The rising and falling arc-shaped grooves are arranged alternately and are connected end to end. For each rotation of the rotating rod 15, the lifting plate 18 will slide up and down twice, thereby compressing and stretching the airbag 20 twice.

[0037] A first motor 2 is fixedly installed inside the workbench 1. The output shaft of the first motor 2 is fixedly mounted on a turntable 3. The top of the turntable 3 is coaxially and fixedly connected to the bottom of the rotating rod 15. Two transmission components 31 are fixedly mounted on the outer surface of the turntable 3. The two transmission components 31 are symmetrically arranged and spaced 180 degrees apart. Each transmission component 31 contains multiple teeth. At the same time, a toothed ring 5 is fixedly fitted on the outer arc surface of the rotating table 4. Both transmission components 31 are engaged with the toothed ring 5 in a contact-type transmission.

[0038] Working principle: When in use, place several containers on the top of the placement platform 9, start the second motor 6, and drive the first gear 7 to rotate through the output shaft of the second motor 6. The first gear 7 drives several second gears 8 to rotate synchronously, and the second gears 8 drive the placement platform 9 to rotate through the connecting rod 25.

[0039] During the rotation of the placement platform 9, the sliding cooperation between the limiting rod 12 and the guide groove 13 drives the limiting plate 14 to slide towards the central axis of the placement platform 9 under the limiting guidance of the limiting groove 10, thereby centering and clamping the container on the top of the placement platform 9.

[0040] Initial state as Figure 2 As shown, the filling gun 19 is directly opposite the container on the lower platform 9. The first motor 2 is started, and the output shaft of the first motor 2 drives the turntable 3 to rotate 90 degrees clockwise. At this time, one of the transmission components 31 is just disengaged from the gear ring 5, while the other transmission component 31 is not yet engaged with the gear ring 5, so the turntable 4 does not rotate.

[0041] Meanwhile, the turntable 3 in the above process will also drive the rotating rod 15 to rotate synchronously. Under the sliding cooperation of the sliding block 17 and the slide groove 16, the lifting plate 18 will rise and gradually compress the air bag 20. Thus, under the restriction of the valve in the second glue delivery tube 22, the adhesive in the air bag 20 will be squeezed into the first glue delivery tube 21 and sprayed into the container through the filling gun 19 to achieve quantitative filling.

[0042] Subsequently, the output shaft of the first motor 2 continues to rotate 90 degrees clockwise. The lifting plate 18 will descend and stretch the airbag 20 under the sliding cooperation of the sliding block 17 and the sliding groove 16, so that negative pressure adsorption is generated in the airbag 20. Thus, under the restriction of the valve in the first glue delivery pipe 21, the adhesive in the material box 23 is delivered to the airbag 20 to achieve material replenishment.

[0043] At the beginning of this process, another transmission component 31 just comes into contact with the gear ring 5 and engages. As the rotation continues, the transmission component 31 drives the rotating table 4 to rotate through the gear ring 5, thereby rotating the other placement table 9 to directly below the filling gun 19. The transmission component 31 also just reaches the initial position of the other transmission component 31, thus realizing the timely replacement of the container and the quantitative feeding of the adhesive.

[0044] Following the above steps, all containers can be filled. After filling is complete, control the output shaft of the second motor 6 to rotate in the opposite direction, release the limit on the containers, and remove the containers.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
