Description

Technical Field

[0001] This utility model relates to a filling equipment, and more particularly to a continuous quantitative filling equipment for producing sealant. Background Technology

[0002] Sealant typically refers to a product used to seal or seal specific surfaces, seams, or materials. They can be liquids, pastes, or gels, and after application, they form a protective film to prevent the passage of moisture, air, or other substances. Continuous quantitative filling of sealants refers to an efficient and precise packaging method for this special material in industrial production. Specifically, it involves using specially designed automated equipment to continuously and accurately fill the sealant into the corresponding container (such as a bottle or can) according to a preset dosage (such as 50ml, 100ml, etc.).

[0003] Patent CN215160920U discloses a continuous quantitative filling machine for sealant production. This patent, through the combination of a blower box, fan, and exhaust vents, can blow air onto the conveyor belt during filling to dissipate heat from the sealant inside the filled bottles, preventing expansion. Camphor balls in the first and second hemispheres, combined with the airflow, can blow air around the bottles during filling, repelling insects with scent and airflow, preventing them from falling into the bottles and indirectly protecting the company's image. Overall, it is convenient to use and suitable for mass production. However, this patent still has shortcomings in practical application: it fails to fully solve the problem of continuous quantitative filling of the sealant, resulting in inconsistent sealant volume in each bottle. This not only affects product quality consistency but may also lead to rework later, severely impacting production efficiency.

[0004] Therefore, it is necessary to design a continuous quantitative filling equipment for sealing agent production to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a continuous quantitative filling equipment for sealing agent production.

[0006] The technical solution is: a continuous quantitative filling equipment for sealing agent production, comprising a base, a support frame, a storage tank, an inlet pipe, a discharge pipe, a solenoid valve 1, a check valve 1, a buffer cylinder, a hydraulic cylinder, an extrusion plate, a guide pipe, a check valve 2, a discharge pipe, a check valve 3, a solenoid valve 2, a filling head, and a controller. A support frame is fixedly connected between the two sides of the top of the base. A storage tank is fixedly connected to one side of the support frame. An inlet pipe is connected to one side of the storage tank, and a discharge pipe is connected to the other side of the storage tank. A solenoid valve 1 is fixedly connected to one end of the discharge pipe, and a check valve 1 is rotatably connected to the inner wall of the other end of the discharge pipe. A hydraulic cylinder is fixedly connected to the other side of the support frame. There is a slowing cylinder, one side wall of which is connected to and communicates with one end of the discharge pipe. A hydraulic cylinder is fixedly connected to the top of the slowing cylinder. The piston of the hydraulic cylinder passes through the top of the slowing cylinder and is fixedly connected to an extrusion plate. The extrusion plate is located inside the slowing cylinder and is slidably connected to the inner wall of the slowing cylinder. A guide pipe is connected to and communicates with one side of the extrusion plate. A one-way valve is rotatably connected to the inner wall of the guide pipe. A discharge pipe is connected to and communicates with the bottom of the slowing cylinder. A one-way valve is rotatably connected to the inner wall of one end of the discharge pipe. A solenoid valve is fixedly connected to the middle of the discharge pipe. A filling head is connected to and communicates with the other end of the discharge pipe. A controller is fixedly connected to one side of the base. The hydraulic cylinder is electrically connected to the controller.

[0007] Furthermore, it also includes rollers, sprockets, chains, chain plates, and a motor. Rollers are symmetrically and rotatably connected to both sides of the base. Both rollers are located between the inner walls of both sides of the base. Sprockets are fixed to both ends of both rollers. Chains are wound around the two sprockets on both sides. Chain plates are fixed at equal intervals between the inner walls of the two chains. A motor is fixed to one side of the base. The motor output shaft passes through the outer wall of one side of the base and is fixed to one of the rollers. The motor is located to the left of the controller and is electrically connected to the controller.

[0008] Furthermore, it also includes a limit seat, a guide rod, a spring, and a limit ring. The guide rod, spring, and limit ring are a group, each group is located on the top of the chain plate, and every two chain plates are a group, with one of the chain plates having a group of limit seats, guide rods, springs, and limit rings on its top. Limit seats are symmetrically fixed to the top of the chain plates. A guide rod is slidably connected to the side of each pair of limit seats that are close to each other. A spring is fixed between the guide rod and the limit seat. A limit ring is fixed to the side of each guide rod that is close to each other. The limit rings in the same group are distributed opposite each other.

[0009] Furthermore, it also includes a laser transmitter and a laser receiver. The laser transmitter is fixedly attached to one side of the top of the base, and the laser receiver is fixedly attached to the other side of the top of the base. The laser transmitter and the laser receiver are symmetrically distributed, and both the laser transmitter and the laser receiver are electrically connected to the controller.

[0010] Furthermore, the outer wall of the slow-feeding cylinder is symmetrically marked with graduation lines on both the front and back.

[0011] Furthermore, a sealing strip is tightly wrapped around both the upper and lower edges of the extrusion plate. This sealing strip covers the vertical surface of the extrusion plate and extends to the edge of its horizontal surface.

[0012] The beneficial effects are as follows: 1. This utility model uses a cylinder piston to retract upwards and drive the extrusion plate to move upwards, so that a certain space is formed between the bottom of the extrusion plate and the bottom of the slowing cylinder; the sealant inside the storage box is first transported to the slowing cylinder through the discharge pipe, and then enters the space between the bottom of the extrusion plate and the bottom of the slowing cylinder through the guide pipe, and is finally output by the filling head through the discharge pipe, thereby effectively realizing continuous quantitative filling of sealant.

[0013] 2. This utility model starts the motor through the controller. The motor output shaft drives the left roller and sprocket to rotate clockwise. The chain drives the right roller and sprocket to rotate clockwise synchronously, so that the chain plate, which is kept horizontal, moves continuously from left to right. When the filling bottle is conveyed to the right and is directly below the filling head, the next filling bottle will be automatically placed between the other two limit rings, thereby achieving the effect of continuous automatic placement of filling bottles.

Detailed Implementation

[0023] Example: A continuous quantitative filling equipment for sealing agent production, such as... Figures 1-4 As shown, the system includes a base 1, a support frame 2, a storage tank 3, a feed pipe 4, a discharge pipe 5, a solenoid valve 6, a check valve 7, a buffer cylinder 8, a hydraulic cylinder 9, an extrusion plate 10, a guide pipe 11, a check valve 12, a discharge pipe 13, a check valve 14, a solenoid valve 15, a filling head 16, and a controller 21. The support frame 2 is connected to the front and rear sides of the top of the base 1 by screws. The storage tank 3 is connected to the top of the support frame 2 by screws. The top of the storage tank 3 is connected to and communicates with the feed pipe 4, and the bottom of the storage tank 3 is connected to and communicates with the feed pipe 4. A feeding pipe 5 is provided, with a solenoid valve 6 installed at the upper end of the feeding pipe 5 via screws. A one-way valve 7 is rotatably connected to the inner wall of the right end of the feeding pipe 5. A buffer cylinder 8 is connected to the right side of the support frame 2 via screws. The outer wall of the buffer cylinder 8 has symmetrical graduation lines on both the front and back. By observing the graduation lines, the operator can accurately adjust the position of the extrusion plate 10, thereby determining the space between the bottom of the extrusion plate 10 and the bottom of the buffer cylinder 8, ensuring consistent sealing dosage for each filling and improving product quality consistency. The left side wall of the buffer cylinder 8 is connected to the lower... The right end of the feed pipe 5 is connected and open. A hydraulic cylinder 9 is screwed onto the top of the buffer cylinder 8. The piston of the hydraulic cylinder 9 passes through the top of the buffer cylinder 8 and is keyed to an extrusion plate 10. The extrusion plate 10 is located inside the buffer cylinder 8 and is slidably connected to the inner wall of the buffer cylinder 8. A sealing strip is tightly wrapped around both the upper and lower edges of the extrusion plate 10. This sealing strip covers the vertical surface of the extrusion plate 10 and extends to its horizontal edge, ensuring a good seal between the extrusion plate 10 and the inner wall of the buffer cylinder 8, effectively preventing leaks. During the extrusion process, the agent leaks from the edge of the extrusion plate 10. The left side of the extrusion plate 10 is connected to and connected to the guide pipe 11. The inner wall of the guide pipe 11 is rotatably connected to the one-way valve 12. The bottom right side of the slowing cylinder 8 is connected to and connected to the discharge pipe 13. The upper inner wall of the discharge pipe 13 is rotatably connected to the one-way valve 3. The middle part of the discharge pipe 13 is equipped with the solenoid valve 15 by screws. The lower end of the discharge pipe 13 is connected to and connected to the filling head 16. The front outer wall of the base 1 is equipped with the controller 21 by screws. The hydraulic cylinder 9 is electrically connected to the controller 21.

Rollers 17 are symmetrically and rotatably connected to the left and right sides of the base 1. Both rollers 17 are located between the inner walls of the front and rear sides of the base 1. Sprockets 18 are keyed to the front and rear ends of both rollers 17. Chains 19 are wound around the two sprockets 18 on the front and rear sides. Chain plates 1901 are keyed at equal intervals between the inner walls of the two chains 19. A motor 20 is installed on the outer front wall of the base 1 by screws. The output shaft of the motor 20 passes through the outer front wall of the base 1 and is keyed to the left roller 17. The motor 20 is located to the left of the controller 21. (Each pair of symmetrically distributed limit seats 22, guide rods 23, springs 24, and limit rings 25 form a group, and each group is...) At the top of the chain plate 1901, each pair of chain plates 1901 forms a group, and one of the chain plates 1901 is provided with a set of limiting seats 22, guide rods 23, springs 24 and limiting rings 25. The top of the chain plate 1901 is symmetrically connected to the limiting seats 22 by screws. The guide rods 23 are slidably connected to the side of each pair of limiting seats 22 that are close to each other. Springs 24 are welded between the guide rods 23 and the limiting seats 22. The end of each pair of guide rods 23 that are close to each other is connected to the limiting rings 25 by screws. The limiting rings 25 in the same group are distributed opposite each other. A laser emitter 26 is installed on the rear side of the top of the base 1 by screws, and a laser receiver 27 is installed on the front side of the top of the base 1 by screws. The laser emitter 26 and the laser receiver 27 are symmetrically distributed front and back. The motor 20, the laser emitter 26 and the laser receiver 27 are all electrically connected to the controller 21.

[0025] When continuous quantitative filling of the produced sealant is required, the staff first place the equipment horizontally in the designated work area and install it in coordination with the equipment for producing and packaging sealant. Specifically, the left side of the continuous quantitative filling equipment for sealant production is closely connected with the equipment for pre-placed filling bottles, and the right side is closely connected with another piece of equipment for packaging and extracting the filled bottles. Then, the feed pipe 4 is connected to another pipe for conveying sealant, and the storage tank 3 is filled with sealant through the feed pipe 4, thus forming a complete production and packaging process. Then, the operator starts the motor 20 via the controller 21. The output shaft of the motor 20 drives the left roller 17 and sprocket 18 to rotate clockwise, and the chain 19 drives the right roller 17 and sprocket 18 to rotate clockwise synchronously, thereby moving the horizontal chain plate 1901 from left to right. At this time, the pre-positioned bottle-filling device places empty bottles one by one on top of the chain plate 1901. Each bottle is located between two limit rings 25, and its bottle body is in contact with the two limit rings 25. During this process, the bottle... The body presses the two limiting rings 25 forward and backward respectively, causing the two guide rods 23 to move forward and backward respectively as the limiting rings 25 move. Both guide rods 23 slide in the middle of the limiting seat 22 on the same side and compress the spring 24, keeping the spring 24 in a contracted state, thereby achieving the effect of fixing and limiting the filling bottle. When the filling bottle is conveyed to the right to the position directly below the filling head 16, the next filling bottle is automatically placed between the other two limiting rings 25, thus achieving the effect of continuously and automatically placing the filling bottle.

[0026] Next, the filling quantity is adjusted according to the capacity of the bottle. For example, when the bottle capacity is 50ml, the operator first adjusts the quantity using the scale lines on the outer wall of the buffer cylinder 8. Initially, the bottom of the extrusion plate 10 is in close contact with the bottom of the buffer cylinder 8 and maintains an absolute seal. Then, the controller 21 starts the hydraulic cylinder 9 and opens the solenoid valve 6, causing the piston of the hydraulic cylinder 9 to retract upwards and move the extrusion plate 10 upwards to the 50ml scale line, so that the space between the bottom of the extrusion plate 10 and the bottom of the buffer cylinder 8 is 50ml. During this process, the sealant inside the storage tank 3 is transported to the buffer cylinder 8 through the discharge pipe 5. When the amount of sealant continuously transported to the top of the extrusion plate 10 exceeds the limits of the one-way valve 12 and the one-way valve 3, the sealant is not blocked by the one-way valve 12 and the one-way valve 3, but instead flows through the guide pipe 1. 1. The material enters between the bottom of the extrusion plate 10 and the bottom of the buffer cylinder 8, and then enters the discharge pipe 13. During this process, the laser of the laser emitter 26 is blocked by the filling bottle being conveyed to the right. The laser receiver 27 receives the relevant signal and transmits the signal to the controller 21. At this time, the controller 21 temporarily shuts down the motor 20, causing the motor 20 to pause driving the rotation of the roller 17, so that the bottle mouth is facing the filling head 16. At this time, the controller 21 activates the solenoid valve 15, allowing the sealant inside the discharge pipe 13 to enter the filling head 16. The filling head 16 fills 50ml of sealant into the empty filling bottle. Subsequently, the equipment responsible for packaging the filling bottle starts working. First, the filling bottle filled with sealant is sealed, and then the filling bottle is removed and placed in the designated area to complete the quantitative filling process of the sealant. After the packaged bottle is removed, the controller 21 restarts the motor 20. The output shaft of the motor 20 drives the left roller 17 and sprocket 18 to rotate clockwise. The chain 19 then drives the right roller 17 and sprocket 18 to rotate clockwise in sync. This reciprocating action achieves continuous quantitative filling of the sealant.
