Description

Technical Field

[0001] This utility model relates to the technical field of glass bottle filling equipment, specifically a glass bottle filling machine that can prevent leakage. Background Technology

[0002] Filling machines are a small category of packaging machines. They are widely used in pharmaceutical, food, and chemical industries. There are various types of filling machines, such as the common glass bottle filling machine, which is filled by a filling head. In the current technology, after the filling head fills the glass bottle, the liquid remaining in the filling head is very easy to drip, and the leaked liquid can easily drip onto the worktable and other equipment, making it difficult to clean.

[0003] In response, a search of announcement number CN212222394U reveals a leak-proof glass bottle filling machine, comprising two parallel fixed plates. Support rods are fixed near the four corners between the fixed plates. A cylinder is bolted to the bottom surface of the upper fixed plate near its front and rear edges. This leak-proof glass bottle filling machine, through its liquid tank, cylinder, filling mechanism, movable plate, and U-shaped plate, ensures that after filling, a spring returns to its original position, causing a sealing block to insert into a sealing groove to form a seal. This design, through the cooperation of the sealing groove, sealing block, pressure block, filling tube, and strip groove, prevents liquid from entering the filling tube after filling, thus avoiding leakage and dripping onto the worktable and other equipment, and preventing unnecessary cleaning and bacterial growth.

[0004] The aforementioned technology discloses a glass bottle filling machine that can prevent leakage. This machine uses a strip groove at the top of the filling tube for liquid flow, which is then blocked when the tube is raised after filling, reducing the amount of liquid flowing downwards. However, it still has the following shortcomings: 1. It cannot quantitatively fill the liquid, making it difficult to automatically control the filling amount according to the filling demand, easily resulting in overfilling or underfilling, and poor filling accuracy; 2. Even with the top of the filling tube blocked, residual liquid inside the tube still drips, resulting in an unsatisfactory anti-leakage dripping effect after filling. Therefore, this application proposes a glass bottle filling machine that can prevent leakage to solve the above-mentioned problems. Utility Model Content

[0023] 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.

[0024] like Figures 1 to 3 As shown, the glass bottle filling machine proposed in this embodiment can prevent leakage, including a U-shaped support plate 1 and a liquid storage tank 2 fixedly connected to the top of the U-shaped support plate 1. A support plate 101 is fixedly connected between the inner walls of the two sides of the U-shaped support plate 1. The top of the support plate 101 is provided with a plurality of positioning holes 102 for inserting glass bottles. A feeding pipe is fixedly connected to the top left side of the liquid storage tank 2, and a drain valve is fixedly connected to the bottom right side of the liquid storage tank 2.

[0025] An electric telescopic rod 201 and a PLC controller 203 are fixedly installed at the bottom of the liquid storage tank 2. The extended end of the electric telescopic rod 201 is fixedly connected to a lifting plate 202 that is slidably sleeved on the U-shaped support plate 1. The top of the lifting plate 202 has two rectangular guide holes that slide in contact with the outer side of the U-shaped support plate 1, serving as a vertical guide for the lifting plate 202. Multiple transparent shells 3 are embedded and fixedly installed on the top of the lifting plate 202. The top of the lifting plate 202 has multiple mounting holes that are fixedly connected to the outer side of the corresponding transparent shell 3. The bottom of the transparent shell 3 is connected to a corresponding... The filling tube 301 above the positioning hole 102 is equipped with a quantitative liquid supply warning component between the top of the transparent shell 3 and the bottom of the liquid storage tank 2. The quantitative liquid supply warning component and the electric telescopic rod 201 are both electrically connected to the PLC controller 203. The electric telescopic rod 201 is used to drive the lifting plate 202 to move up and down. The lifting plate 202 moves down and drives multiple filling tubes 301 to be inserted into the glass bottles to be filled through multiple transparent shells 3. The quantitative liquid supply warning component is used to supply liquid quantitatively into the corresponding transparent shell 3 under the control of the PLC controller 203, and to clearly remind personnel after quantitative supply.

[0026] A sealing plate 5 is slidably fitted on the bottom outer side of the filling tube 301. A food-grade silicone pad is bonded and fixed to the bottom of the sealing plate 5. Both the bottom of the food-grade silicone pad and the bottom of the sealing plate 5 have round through holes that slide onto the corresponding outer side of the filling tube 301, allowing the filling tube 301 to slide through. The top of the sealing plate 5 and the bottom inner side of the filling tube 301 are equipped with the same spring-loaded self-opening and unsealing component, which automatically unseals when the sealing plate 5 is squeezed and automatically seals the bottom of the filling tube 301 when the squeeze is released. The sealing plate 5 is used to squeeze and seal the top of the corresponding glass bottle when the filling tube 301 moves down. The spring-loaded self-opening and unsealing component is used to unseal the bottom of the filling tube 301 for filling when it continues to move down after sealing, and to automatically seal the bottom of the filling tube 301 when it is lifted after filling, so as to prevent a large amount of liquid residue from dripping out of the filling tube 301 after it is lifted.

[0027] Specifically, the quantitative liquid supply warning component includes a solenoid valve 401 fixedly connected to the top of the corresponding transparent shell 3. A liquid flow sensor 402 is fixedly connected to the top of the solenoid valve 401. A food-grade hose 403 is fixedly connected between the top of the liquid flow sensor 402 and the bottom of the liquid storage tank 2. A warning light 4 is fixedly connected to the top left side of the transparent shell 3. The warning light 4, solenoid valve 401, and liquid flow sensor 402 are all electrically connected to the PLC controller 203. The solenoid valve 401, liquid flow sensor 402, food-grade hose 403, and warning light 4 work together to pre-set the flow rate for controlling the solenoid valve 401 to close and the warning light 4 to open according to the filling requirements using the PLC controller 203. The system is set to reset ten seconds after all warning lights 4 are turned on. When the solenoid valve 401 is open, the liquid is supplied into the transparent shell 3 sequentially through the corresponding food-grade hose 403, liquid flow sensor 402, and solenoid valve 401. The liquid flow sensor 402 detects the liquid flow and transmits the flow value to the PLC controller 203. When the preset value is reached, the PLC controller 203 controls the corresponding solenoid valve 401 to close and the warning lights 4 to turn on, so as to achieve the effect of quantitatively supplying liquid into the corresponding transparent shell 3 and clearly reminding personnel after quantitative supply. Ten seconds after all warning lights 4 are turned on, the PLC controller 203 controls the electric telescopic rod 201 to start in reverse to reset and controls the multiple warning lights 4 to turn off.

[0028] Furthermore, the self-opening and unsealing assembly includes a U-shaped guide rod 501 fixedly connected to the top of the corresponding sealing plate 5, and a transparent shell 3 slidably sleeved on the corresponding U-shaped guide rod 501. The bottom inner wall of the transparent shell 3 has two vertical guide holes, both of which slide in contact with the outer side of the corresponding U-shaped guide rod 501, allowing the U-shaped guide rod 501 to slide through. A connecting rod 505 is fixedly connected to the top inner wall of the U-shaped guide rod 501. The bottom end of the connecting rod 505 extends into the corresponding filling tube 301 and is fixedly connected to a ball plug 504. A conical sleeve 503 is fixedly connected to the inner bottom of the filling tube 301. The outer bottom of the ball plug 504 is pressed tightly against the inner side of the corresponding conical sleeve 503. Two springs 502 are fixedly connected between the top of the sealing plate 5 and the bottom of the transparent shell 3, and the springs 502 are movably sleeved on the corresponding U-shaped guide rod 501. The U-shaped guide rod 501, connecting rod 505, and ball plug are configured as follows: 504, the conical sleeve 503, and the spring 502 work together. After the sealing plate 5 moves down to contact the top of the glass bottle, it is blocked and restricted by the sealing plate 5. As the transparent shell 3 continues to move down, it slides downward on the corresponding U-shaped guide rod 501 and compresses the spring 502. At the same time, the continuing downward movement of the filling tube 301 drives the corresponding conical sleeve 503 downward to separate from the sealing ball 504, releasing the bottom seal and allowing the filling process to begin. When it rises after filling, the elastic force of the spring 502 tightens the seal. Under the action of the filling tube 301, when it moves upward, it first drives the conical sleeve 503 to move upward and clamp and seal with the plug ball 504. After sealing, the corresponding plug ball 504, connecting rod 505 and U-shaped guide rod 501 drive the sealing plate 5 to rise and reset, so as to achieve the effect of directly sealing the bottom of the filling tube 301 after filling. By using the bottom sealing, it can prevent some liquid from remaining in the filling tube 301 after rising and leaking and dripping, thus improving the anti-leakage effect.

[0029] The usage method of this embodiment is as follows: When using the leak-proof glass bottle filling machine, insert the glass bottles to be filled into the corresponding positioning holes 102. The PLC controller 203 is pre-set according to the filling requirements to control the flow rate values ​​for closing the solenoid valve 401 and opening the warning light 4. It is also pre-set to reset ten seconds after all warning lights 4 are turned on. During filling, the operator controls the PLC controller 203 to drive the electric telescopic rod 201 forward and open multiple solenoid valves 401. The electric telescopic rod 201 drives the lifting plate 202 downward. The lifting plate 202 drives multiple transparent shells 3 downward. The transparent shells 3 sequentially stretch the food-grade hose 403 through multiple solenoid valves 401 and multiple liquid flow sensors 402. Simultaneously, the multiple transparent shells 3 drive multiple filling tubes 301 downward. The filling tubes 301 drive the corresponding sealing plates 5 downward. After the sealing plates 5 reach the top of the glass bottle, they are blocked and restricted. At this time, when the transparent shells 3 continue to move downward, they will... The guide rod 501 slides downwards and compresses the spring 502. At the same time, the filling tube 301 continues to move downwards, causing the corresponding conical sleeve 503 to separate downwards from the ball stopper 504, releasing the bottom seal. When the solenoid valve 401 is opened, the liquid is supplied into the transparent shell 3 through the corresponding food-grade hose 403, liquid flow sensor 402 and solenoid valve 401 in sequence, and then filled into the corresponding glass bottle through the filling tube 301. The liquid flow sensor 402 detects the liquid flow in real time and transmits the flow value to the PLC controller 203. When the preset value is reached, the PLC controller 203 controls the corresponding solenoid valve 401 to close and the warning light 4 to turn on, realizing the effect of quantitative filling into the corresponding transparent shell 3 and clearly reminding the personnel after quantitative supply. It is convenient to automatically control the filling amount according to the filling demand, avoid the phenomenon of filling too much or too little, and improve the filling accuracy. Ten seconds after all the warning lights 4 are turned on, the PLC controller 203 controls the electric telescopic rod 201 to start in reverse and reset, and controls the multiple warning lights 4 to turn off.

[0030] When the electric telescopic rod 201 reverses and resets to drive the lifting plate 202 to rise, the lifting plate 202 drives multiple transparent shells 3 to rise and reset. The transparent shells 3 drive the corresponding filling tubes 301 to rise. During the initial lifting process, under the tension of the spring 502, when the filling tube 301 moves upward, it first drives the conical sleeve 503 to move upward and clamp and seal with the ball 504. After sealing, the corresponding ball 504, connecting rod 505 and U-shaped guide rod 501 drive the sealing plate 5 to rise and reset in sequence. This achieves the effect of directly sealing the bottom of the filling tube 301 after filling. By sealing the bottom, it can prevent some liquid from remaining in the filling tube 301 after lifting and leaking and dripping, thus improving the anti-leakage and dripping effect.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
