Description

Technical Field

[0001] This utility model relates to the field of manufacturing processing technology, specifically to a glue tank with liquid level control. Background Technology

[0002] In manufacturing industries that use large amounts of glue, such as paper processing and packaging material production, glue tanks are used. These tanks are primarily for storing glue, ensuring a continuous supply. The size of the glue tank can be designed according to the production scale and glue usage; small tanks may only be a few cubic meters, while large tanks can reach tens of cubic meters. Glue tanks are usually enclosed to prevent glue evaporation and environmental pollution, and they are equipped with appropriate stirring devices to ensure the glue composition is uniform. For example, in cardboard box production, the glue in the tank is piped to the coating equipment, and then applied to the joints of the cardboard boxes for bonding.

[0003] In the use of glue tanks, liquid level control is a critical aspect. Precise liquid level control ensures a stable supply of glue, preventing production interruptions due to insufficient glue or waste and environmental pollution caused by excessive glue overflow. In automated packaging production lines, if the glue level in the glue tank is too low, the glue application device may malfunction, affecting the packaging quality of the product; while if the level is too high, glue may overflow from the glue tank, damaging the equipment and increasing cleaning costs.

[0004] Therefore, in the manufacturing process, it is necessary to precisely control the glue level inside the glue tank to avoid insufficient glue supply during processing, which would lead to low work efficiency and ensure the stability and continuity of glue supply during processing. Hence, a glue tank with liquid level control is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a glue tank with liquid level control, which has advantages such as high precision and good stability, and solves the problem of unstable supply caused by low precision in glue level control during manufacturing processes.

[0006] To achieve the aforementioned high accuracy and good stability, this utility model provides the following technical solution: a glue tank with liquid level control, comprising a tank body, an infusion pump installed at the top of the tank body, and a suction pump installed at the top of the tank body, wherein a control component is installed inside the tank body;

[0007] The control assembly includes several electric telescopic rods fixedly installed on the top wall of the pool body, an adjusting cylinder fixedly installed at the bottom of the electric telescopic rods, several connecting rods fixedly installed on the top wall of the adjusting cylinders, a limiting plate fixedly installed at the bottom of the connecting rods, a liquid level float movably connected inside the limiting plate, an infrared transmitter set on the side of the liquid level float, an infrared receiving plate fixedly installed on the inner wall of the pool body, and a main control module fixedly installed on the top of the pool body.

[0008] Furthermore, a liquid supply pipe is provided on one side of the infusion pump, which extends to the inner bottom wall of the pool. A support pipe is provided on the inner bottom wall of the pool, and a circular feeding tray is fixedly installed on the top of the support pipe.

[0009] Furthermore, the circular feeding tray has an internal cavity and several liquid outlet holes at the top. The end of the liquid supply pipe is connected to the side of the support pipe, and the top of the support pipe is embedded in the internal cavity of the circular feeding tray.

[0010] Furthermore, a suction pipe is provided on one side of the suction pump. One end of the suction pipe passes through the top wall of the pool and the regulating cylinder to the inside of the regulating cylinder. The part of the suction pipe located on the outside of the regulating cylinder is a flexible pipe.

[0011] Furthermore, the top of the regulating cylinder is provided with a circular liquid inlet, the top of the limiting plate is provided with a sliding groove, and the inner side of the sliding groove is provided with several evenly distributed limiting arc grooves.

[0012] Furthermore, the liquid level buoy includes a float plate, which has a conical structure and a vertical rod that is inserted and fixed at the top. A counterweight block that is inserted and fixed at the top of the vertical rod is also provided.

[0013] Furthermore, the float plate vertically penetrates the sliding groove and is slidably connected to the inner wall of the sliding groove, and the side of the float plate is provided with several limiting slide rods that cooperate with the limiting arc groove.

[0014] Compared with the prior art, this utility model provides a glue tank with liquid level control, which has the following features:

[0015] Beneficial effects:

[0016] 1. This glue tank with liquid level control draws external glue into the supply pipe by starting the infusion pump. The glue inside the supply pipe passes through the support pipe and enters the circular feeding tray. It then enters the tank body through the discharge hole at the top of the circular feeding tray. After the top liquid level overflows the inside of the regulating cylinder, the glue enters the inside of the regulating cylinder through the circular inlet. The continuous flow of glue into the regulating cylinder supports the bottom of the float plate, raising the float plate.

[0017] 2. This glue tank with liquid level control uses the buoyancy of the glue to raise the float plate, which in turn raises the infrared transmitter on the side of the vertical rod, preventing the infrared receiver from receiving a signal. At this point, the main control module stops the infusion pump and starts the suction pump to extract the glue from the regulating cylinder through the suction pipe. Once the infrared receiver receives a signal again, the main control module stops the suction pump, thus maintaining a stable glue level inside the tank. This solves the problem of unstable glue supply caused by low precision in glue level control during manufacturing processes. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 3 In this embodiment, a glue tank with liquid level control includes a tank body 1, an infusion pump 2 disposed on the top of the tank body 1, and a suction pump 3 disposed on the top of the tank body 1. A control component 4 is disposed inside the tank body 1. The control component 4 includes several electric telescopic rods 41 fixedly installed on the inner top wall of the tank body 1, an adjusting cylinder 42 fixedly installed on the bottom of the electric telescopic rods 41, several connecting rods 43 fixedly installed on the inner top wall of the adjusting cylinders 42, a limiting plate 44 fixedly installed on the bottom of the connecting rods 43, a liquid level float 45 movably connected inside the limiting plate 44, an infrared transmitter 46 disposed on the side of the liquid level float 45, an infrared receiving plate 47 fixedly installed on the inner side wall of the tank body 1, and a main control module 48 fixedly installed on the top of the tank body 1.

[0024] It should be noted that when using pool 1, a sealing cover plate needs to be installed on the top to seal the glue pool, preventing the glue from coming into direct contact with the outside world and preventing the glue from evaporating and polluting the environment.

[0025] In this embodiment, a liquid supply pipe 21 is provided on one side of the infusion pump 2. The liquid supply pipe 21 extends to the inner bottom wall of the pool body 1. A support pipe 22 is provided on the inner bottom wall of the pool body 1. A circular feeding tray 23 is fixedly installed on the top of the support pipe 22. The circular feeding tray 23 has a cavity inside and several liquid outlet holes on the top. The end of the liquid supply pipe 21 is connected to the side of the support pipe 22. The liquid supply pipe 21 delivers the adhesive liquid drawn by the infusion pump 2 to the support pipe 22. The top of the support pipe 22 is embedded in the inner cavity of the circular feeding tray 23. While fixing the circular feeding tray 23, the support pipe 22 is connected to the circular feeding tray 23 to supply the circular feeding tray 23.

[0026] In this embodiment, a suction pipe 31 is provided on one side of the suction pump 3. One end of the suction pipe 31 penetrates the top wall of the pool body 1 and the regulating cylinder 42 to the inside of the regulating cylinder 42. The suction pump 3 extracts the adhesive liquid inside the regulating cylinder 42 through the suction pipe 31. The part of the suction pipe 31 located on the outside of the regulating cylinder 42 is a flexible pipe. When the regulating cylinder 42 is contracted by the electric telescopic rod 41, the regulating cylinder 42 will change in height. The flexible suction pipe 31 will not affect the raising and lowering of the regulating cylinder 42.

[0027] In this embodiment, a circular liquid inlet 421 is provided at the top of the regulating cylinder 42. When the liquid inside the pool 1 exceeds the top of the regulating cylinder 42, it will enter the interior of the regulating cylinder 42 through the circular liquid inlet 421. A sliding groove 441 is provided at the top of the limiting plate 44, and several evenly distributed limiting arc grooves 442 are provided on the inner side of the sliding groove 441. The level float 45 includes a float plate 451, which has a conical structure and a vertical rod 452 fixed at the top. The conical shape of the float plate 451 can ensure that the float plate 451 remains vertical to a certain extent, while preventing adhesive residue from remaining on the surface of the float plate 451 and affecting its floating. A counterweight 453 is fixed at the top of the vertical rod 452. The counterweight 453 can adjust the buoyancy required for the float plate 451, thereby adjusting the height of the float plate 451 on the adhesive surface. The float plate 451 vertically passes through the sliding groove 441 and is slidably connected to the inner wall of the sliding groove 441. When the bottom of the float plate 451 is supported by the adhesive, it can float upward. Several limiting slide rods 454 are provided on the side of the float plate 451 to cooperate with the limiting arc groove 442. The limiting slide rods 454 ensure that the float plate 451 always remains vertical when it floats.

[0028] The working principle of the above embodiments is as follows:

[0029] By starting the infusion pump 2, the external adhesive is drawn into the interior of the supply pipe 21. The adhesive inside the supply pipe 21 passes through the support pipe 22 and enters the interior of the circular feeding tray 23. It then enters the interior of the tank body 1 through the discharge hole at the top of the circular feeding tray 23. After the top liquid level of the adhesive overflows the interior of the regulating cylinder 42, the adhesive enters the interior of the regulating cylinder 42 through the circular inlet 421. As the adhesive continuously flows into the interior of the regulating cylinder 42, it supports the bottom of the float 451, raising the float 451.

[0030] In addition, the buoyancy of the adhesive causes the float plate 451 to rise, which in turn pushes the infrared transmitter 46 on the side of the vertical rod 452 to rise, making the infrared receiver plate 47 unable to receive the signal. At this time, the main control module 48 controls the infusion pump 2 to stop running, and at the same time starts the liquid extraction pump 3 to extract the adhesive from the regulating cylinder 42 through the liquid extraction pipe 31. After the infrared receiver plate 47 receives the signal again, the main control module 48 stops the liquid extraction pump 3, thereby maintaining a stable adhesive level inside the pool 1. This solves the problem of unstable supply caused by low precision in adhesive level control during manufacturing processes.
