Description

Technical Field

[0001] This utility model relates to the field of laundry detergent filling, and in particular to a laundry detergent filling anti-overflow device. Background Technology

[0002] Laundry detergent filling is a key step in the laundry detergent production process. It refers to the process of accurately filling the produced laundry detergent into packaging containers (such as plastic bottles, buckets, etc.) according to certain specifications and quantities. The filling equipment is cleaned and disinfected to ensure that the equipment meets hygiene standards. At the same time, clean packaging containers are prepared, and the produced laundry detergent is stored in a suitable storage tank.

[0003] In related technologies, laundry detergent filling equipment uses a filling head that is directly inserted into the bottle opening for filling. If the filling control precision is insufficient or the response is delayed, overflow is very likely to occur. Excess laundry detergent will spill out of the bottle opening, which will not only dirty the bottle but may also contaminate the surface of the equipment that transports the laundry detergent bottles. This overflow phenomenon not only affects the appearance and quality of the laundry detergent but may also cause subsequent filling processes to be unsmooth, thereby affecting the efficiency and output of the entire production line.

[0004] Therefore, it is necessary to provide a laundry detergent filling anti-overflow device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a laundry detergent filling anti-overflow device.

[0009] An overflow prevention assembly includes a filling tube connected to the bottom of a laundry detergent filling hopper. A fixed hopper is fixedly connected to the bottom surface of the filling tube. A return pipe is connected to the side wall of the fixed hopper. A collection box is fixedly connected to the side wall of the laundry detergent filling hopper. The top of the return pipe extends into the interior of the collection box. A first one-way valve is connected to the surface of the return pipe. A second one-way valve is connected to the side wall of the collection box. A piston tube is connected to the end of the second one-way valve away from the laundry detergent filling hopper. A sealing plate is slidably connected inside the piston tube. A third one-way valve is connected to the top of the piston tube.

[0010] A transmission assembly for driving the sealing sheet.

[0011] Preferably, the transmission assembly includes a main assembly frame, which is fixedly connected to the side wall of the collection box. A servo motor is fixedly connected to the top of the main assembly frame, and a disc is fixedly connected to the output end of the servo motor. A round rod is fixedly connected to the side wall of the disc, and a transmission frame is sleeved on the surface of the round rod. A metal rod is fixedly connected to the bottom of the sealing plate, and the top of the transmission frame is fixedly connected to the bottom of the metal rod.

[0012] Preferably, a silicone ring is fixedly connected to the surface of the fixed bucket, and the silicone ring is located at the top of the bottom end of the return pipe.

[0016] Compared with related technologies, the laundry detergent filling anti-overflow device provided by this utility model has the following beneficial effects:

[0017] 1. In the process of filling laundry detergent, first install the bracket onto a standardized filling device, then connect the external laundry detergent supply pipe to the left end of the laundry detergent filling hopper. Next, activate the electric push rod to push the laundry detergent filling hopper downwards, allowing the fixed hopper to be inserted into the mouth of the laundry detergent bottle and sealed with a silicone ring. Then, laundry detergent can be filled. Simultaneously, activate the servo motor to rotate the disc, which in turn rotates the rod, causing the transmission frame to move up and down reciprocally. This reciprocating movement of the transmission frame drives the metal rod... The metal rod moves, causing the sealing plate to move. When the sealing plate moves downward, it draws air from inside the collection box into the piston tube. As the air inside the collection box decreases, it draws air from the return pipe, causing the return pipe to draw detergent from the bottle opening. The first one-way valve ensures that detergent does not flow downward through the return pipe. The return pipe draws detergent into the collection box. Then, the sealing plate moves upward, and the piston tube discharges excess air through the third one-way valve. The process of drawing detergent is repeated to prevent overflow.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 5 A laundry detergent filling overflow prevention device, comprising:

[0026] Laundry detergent filling hopper 1 and support 2 located on top of laundry detergent filling hopper 1;

[0027] Electric push rod 3 is fixedly connected to the top of bracket 2, and the telescopic end of electric push rod 3 is fixedly connected to the top of laundry detergent filling hopper 1.

[0028] An overflow prevention assembly 4 includes a filling tube 41 connected to the bottom of the laundry detergent filling hopper 1. A fixed hopper 42 is fixedly connected to the bottom surface of the filling tube 41. A return pipe 43 is connected to the side wall of the fixed hopper 42. A collection box 44 is fixedly connected to the side wall of the laundry detergent filling hopper 1. The top of the return pipe 43 extends into the interior of the collection box 44. A first one-way valve 45 is connected to the surface of the return pipe 43. A second one-way valve 46 is connected to the side wall of the collection box 44. A piston tube 47 is connected to the end of the second one-way valve 46 away from the laundry detergent filling hopper 1. A sealing plate 48 is slidably connected inside the piston tube 47. A third one-way valve 49 is connected to the top of the piston tube 47.

[0029] Transmission assembly 5, which is used to drive the sealing sheet 48;

[0030] The transmission assembly 5 includes a general assembly frame 51, which is fixedly connected to the side wall of the collection box 44. A servo motor 52 is fixedly connected to the top of the general assembly frame 51. A disc 53 is fixedly connected to the output end of the servo motor 52. A round rod 54 is fixedly connected to the side wall of the disc 53. A transmission frame 55 is sleeved on the surface of the round rod 54. A metal rod 56 is fixedly connected to the bottom of the sealing plate 48. The top of the transmission frame 55 is fixedly connected to the bottom of the metal rod 56.

[0031] A silicone ring 6 is fixedly connected to the surface of the fixed bucket 42, and the silicone ring 6 is located at the top of the bottom end of the return pipe 43.

[0032] In the specific implementation process, during the laundry detergent filling process, firstly, the bracket 2 needs to be installed on the pre-configured filling equipment. Next, the external laundry detergent supply pipe is connected to the left end of the laundry detergent filling hopper 1 of the filling equipment. After the preparation is complete, the electric push rod 3 is activated, which allows the laundry detergent filling hopper 1 to move downwards, thereby allowing the fixed hopper 42 to be inserted into the inside of the laundry detergent bottle mouth. To ensure the sealing during the filling process, a silicone ring 6 is used for sealing. Then, the filling of laundry detergent can begin. At the same time, the servo motor 52 is activated. The operation of the servo motor 52 will drive the disc 53 to rotate. The rotation of the disc 53 will further drive the round rod 54 to rotate. The rotation of the round rod 54 will drive the transmission frame 55 to move up and down reciprocally. This reciprocating movement of the transmission frame 55 can drive the metal rod 56 to move accordingly. The movement of the metal rod 56 will cause the sealing plate 48 to move downwards. When the sealing plate 48 moves downwards, it will fill the empty space inside the collection box 44. Air is drawn into the piston tube 47. As the air inside the collection tank 44 decreases, a negative pressure is created, which draws air from the return tube 43. This negative pressure effect allows the return tube 43 to draw laundry detergent from the bottle opening. To prevent the detergent from flowing downwards during the return process, a first one-way valve 45 ensures one-way flow in the return tube 43. After the return tube 43 draws the detergent into the collection tank 44, the sealing plate 48 moves upward, and the piston tube 47 discharges excess air through the third one-way valve 49. This reciprocating extraction process effectively prevents the overflow of laundry detergent. During the collection of laundry detergent in the collection tank 44, the operator can observe and monitor the detergent volume inside the collection tank 44 in real time through the observation window 10. When the detergent in the collection tank 44 reaches a certain level, the valve at the bottom of the collection tank 44 needs to be opened in time to discharge the detergent. This ensures the normal supply and use of laundry detergent and achieves the effect of preventing overflow.

[0033] refer to Figure 5 As shown, an end cap 7 is fixedly connected to the end of the round rod 54 away from the disc 53. The end cap 7 is located on the side of the transmission frame 55 away from the disc 53.

[0034] Furthermore, during the transmission process between the round rod 54 and the transmission frame 55, the end cover 7 effectively protects the side wall of the transmission frame 55, which can effectively prevent the round rod 54 from detaching from the transmission frame 55, thus making it more convenient and smooth for the user to use.

[0035] refer to Figure 4 As shown, multiple positioning rods 8 are fixedly connected to the top of the transmission frame 55, and multiple positioning rings 9 are slidably connected to the surfaces of the multiple positioning rods 8. All multiple positioning rings 9 are fixedly connected to the surface of the piston tube 47.

[0036] Furthermore, when the transmission frame 55 moves up and down, the interaction between the positioning rod 8 and the positioning ring 9 can precisely restrict the transmission frame 55, which can effectively prevent the transmission frame 55 from shaking and deviating during the movement, and ensure the stability and reliability of the transmission frame 55.

[0037] refer to Figure 1 As shown, the front of the collection box 44 is fitted with an observation window 10.

[0038] Furthermore, during the process of collecting laundry detergent in the collection box 44, the capacity of laundry detergent inside the collection box 44 can be observed and monitored in real time through the observation window 10. When the storage reaches a certain level, the valve at the bottom of the collection box 44 needs to be opened in time to facilitate the timely discharge of laundry detergent and ensure the normal supply and use of laundry detergent.

[0039] The working principle of the laundry detergent filling anti-overflow device provided by this utility model is as follows: During the filling of laundry detergent, the bracket 2 is first installed on a uniform filling equipment. Then, the external laundry detergent supply pipe is connected to the left end of the laundry detergent filling hopper 1. Then, the electric push rod 3 is activated, which can push the laundry detergent filling hopper 1 downward, so that the fixed hopper 42 can be inserted into the inside of the laundry detergent bottle mouth and sealed by the silicone ring 6. Then, the laundry detergent can be filled. At the same time, the servo motor 52 is activated, which drives the disc 53 to rotate. The rotation of the disc 53 drives the circular rod 54 to rotate. The circular rod 54 drives the transmission frame 55 to move up and down. The up and down movement of the transmission frame 55 drives the metal rod 56 to move. The metal rod 56 drives the sealing plate 48 to move. When the sealing plate 48 moves downward, it can draw the air out of the collection box 44. As the air inside the collection tank 44 decreases, it draws air from the return pipe 43, causing the return pipe 43 to draw detergent from the bottle opening. The first one-way valve 45 ensures that detergent does not flow downwards from the return pipe 43. The return pipe 43 draws detergent into the collection tank 44. Then, the sealing plate 48 moves upward, and the piston tube 47 releases excess air through the third one-way valve 49. This process repeats to prevent overflow. During detergent collection, the capacity of the collection tank 44 can be monitored in real-time through the observation window 10. When a certain level is reached, the valve at the bottom of the collection tank 44 needs to be opened to facilitate timely detergent discharge, ensuring a normal supply and use of detergent and preventing overflow.
