Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive production, and particularly relates to an adhesive filling mechanism. Background Art

[0002] During the liquid filling process, liquid often splashes, generally due to too fast filling speed or unstable filling air pressure. Especially during the filling process of adhesives, due to the certain viscosity of adhesives, long-term use will cause pipeline blockage, so the sudden release of pressure during filling will cause the adhesive to splash.

[0003] This kind of splashing phenomenon will, on the one hand, lead to unstable filling volume, and on the other hand, the splashed adhesive will affect the normal operation of the conveyor belt.

[0004] CN218879422U discloses a speed control filling machine for preventing impact splashing at the end of filling, including: a conveying roller table, a conveying mechanism for conveying filling containers, a lifting and conveying table for lifting the container is arranged in the middle section of the conveying roller table, a storage oil cylinder for storing injected oil liquid is arranged at the rear end of the conveying roller table, a conveying control console for controlling the oil injection volume of the equipment is arranged on one side of the storage oil cylinder, and an extension bracket is connected to one side of the conveying control console. This speed control filling machine for preventing impact splashing at the end of filling for lubricating oil can avoid liquid splashing caused by fast flow rate when the container is almost full during filling of lubricating oil. The device adopts automatic control and uses a piston injection pump to regulate the injection volume and injection flow rate, so as to achieve the purpose of preventing oil splashing. However, it is still difficult to solve the situation of adhesive splashing caused by the sudden release of pressure during the filling process of adhesives.

[0005] Based on this, the technical problem to be solved in this case is: how to solve the problem of adhesive splashing during the filling process of adhesives. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides an adhesive filling mechanism, which can prevent the adhesive from splashing and accurately control the falling point of filling, and can further prevent the adhesive from splashing out of the tank to be filled.

[0007] The technical solution of the utility model is:

[0008] An adhesive filling mechanism includes a base, a filling nozzle, and a lifting unit. The lifting unit is arranged on the base and is used to drive the filling nozzle to move vertically up and down. It also includes a positioning unit for positioning the tank to be filled. The positioning unit is arranged on the base and is provided with a splash-proof block for preventing the adhesive from splashing; the splash-proof block can wrap the connection between the bottle mouth of the tank to be filled and the filling nozzle.

[0009] One of the technical solutions in the above technical solutions of the present utility model has at least one of the following advantages or beneficial effects:

[0010] The filling nozzle of the present utility model can move up and down along with the lifting unit. During filling, the filling nozzle can approach the tank body to be filled, reducing the height difference between the two, thereby achieving a certain anti-splash effect. In addition, the present utility model adjusts the tank body to be filled through the positioning unit, making the axis of the tank body to be filled coincide with the axis of the filling nozzle, thereby further preventing splashing. On this basis, a splash-proof block is also provided on the positioning unit. The splash-proof block wraps the connection between the bottle mouth of the tank body to be filled and the filling nozzle during filling, and can avoid splashing caused by unstable spraying direction of the adhesive due to pipeline blockage.

The positioning unit 4 is arranged on the base 1 and is provided with a splash-proof block 43 for preventing adhesive from splashing; the splash-proof block 43 can wrap the connection between the bottle mouth of the tank body to be filled and the filling nozzle 2.

[0016] The filling nozzle 2 of this embodiment can move up and down along with the lifting unit 3. During filling, the filling nozzle 2 can approach the tank body to be filled, reducing the height difference between the two, thereby achieving a certain anti-splash effect. In addition, in this embodiment, the positioning unit 4 is used to adjust the tank body to be filled, so that the axis of the tank body to be filled coincides with the axis of the filling nozzle 2, thereby further preventing splashing. On this basis, a splash-proof block 43 is also provided on the positioning unit 4. During filling, the splash-proof block 43 wraps around the connection between the mouth of the tank body to be filled and the filling nozzle 2, which can prevent splashing caused by unstable spraying direction of the adhesive due to pipeline blockage.

[0017] In this embodiment, specifically, the positioning unit 4 includes a first power assembly and a clamping block 42; the first power assembly is arranged on the base 1; the clamping block 42 is arranged on the power output end of the first power assembly and is used to position the tank body to be filled.

[0018] In this embodiment, more specifically, the first power assembly is a first cylinder 41; the first cylinder 41 is a double-acting cylinder; clamping blocks 42 are respectively arranged on the power output ends on both sides of the first cylinder 41.

[0019] Under the above design, driven by the first cylinder 41, the positioning unit 4 moves the clamping blocks 42 closer to the middle, thereby achieving the purpose of positioning the tank body to be filled. Among them, the first cylinder 41 is a double-acting cylinder, which is beneficial to maintaining stable pressure at both ends and preventing the tank body to be filled from deviating.

[0020] As a preference of this embodiment, a concave portion 421 is provided at the front end of the clamping block 42; the concave portion 421 matches the outer circumference of the tank body to be filled and faces the filling nozzle 2.

[0021] As a further preference of this embodiment, the concave portion 421 matches the outer circumference of the filling port of the tank body to be filled.

[0022] Under the above preference, the clamping block 42 fixes the filling port of the tank body to be filled through the concave portion 421 at the front end. It should be noted that this embodiment only gives one way to make the axis of the tank body to be filled coincide with the axis of the filling nozzle 2, and those skilled in the art can easily think of other implementation methods, such as positioning the body of the tank body to be filled, etc.

[0023] In this embodiment, the splash-proof block 43 is arranged at the front end of the clamping block 42 and wraps around the connection between the tank body to be filled and the filling nozzle 2.

[0024] In this embodiment, the lifting unit 3 includes a guide post 31 disposed on the base 1, a slider 32 slidably connected to the guide post 31, and a second power assembly for driving the slider 32 to move up and down along the guide post 31; the second power assembly is disposed externally, and the power output end of the second power assembly is disposed on the slider 32.

[0025] To stably control the glue output, the filling nozzle 2 includes a third power assembly and a filling body 21; the filling body 21 is provided with a glue inlet, a cavity, and a glue outlet; the glue inlet is communicated with an externally provided adhesive storage device; the third power assembly is disposed on the slider 32, and the power output end of the third power assembly extends into the cavity of the filling body 21 and is provided with a valve ball for closing or opening the glue outlet.

[0026] In this embodiment, the second power assembly and the third power assembly are a second air cylinder 33 and a third air cylinder 22 respectively. In this technical field, the designs of the filling nozzle 2, the second power assembly, and the third power assembly are common technologies, so no further explanation is given in this embodiment, and the internal structure of the filling nozzle 2 is not shown in the figure. The structure can be referred to CN215475892U.

[0027] Under the above design, the working process of this embodiment is that an externally provided conveyor belt transports the cans to be filled to the working position of the filling mechanism. After being detected by an externally provided sensor, a working instruction is sent to the filling mechanism. First, the positioning unit 4 drives the clamping block 42 to approach and clamp the filling port of the can to be filled through the first air cylinder 41. At the same time, the lifting unit 3 works, and the second air cylinder 33 drives the slider 32 to move downward along the guide post 31, making the filling nozzle 2 approach the filling port of the can to be filled. It should be noted that in practical applications, the positioning unit 4 and the lifting unit 3 cooperate to reduce the filling time and improve the filling efficiency. When the can to be filled is positioned and the filling nozzle 2 reaches the specified position, the third air cylinder 22 is controlled to open the glue outlet for filling. After the filling is completed, the third air cylinder 22 is controlled to close the glue outlet, and the second air cylinder 33 and the first air cylinder 41 return to the initial position, waiting for the next filling operation.
