Description

Technical Field

[0001] This utility model relates to the field of adhesive technology, and in particular to an adhesive mixing ratio control device. Background Technology

[0002] Adhesives, also known as "bonding agents" or "adhesives," are substances that firmly bond two or more parts or materials together through interfacial adhesion and cohesion (chemical and physical forces). They include epoxy resins, acrylic resins, polyurethanes, and others. Adhesives are typically composed of a main ingredient and various auxiliary materials.

[0003] In traditional adhesive production processes, proportioning control devices typically use preset fixed parameters to quantitatively add main and auxiliary materials. While this standardized operating mode can meet the production needs of large-scale, conventional proportioning, it has significant limitations in small-batch trial production or formula development stages, requiring adjustments to the parameters of each ingredient, which is inconvenient. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an adhesive mixing ratio control device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adhesive mixing ratio control device, including a base, a mounting frame on the base, a mixing tank vertically slidably arranged inside the mounting frame, a main material pipe on the mounting frame, a main material outlet on the top of the mixing tank corresponding to the output end of the main material pipe, a lifting seat vertically slidably arranged below the mixing tank on the base, an electronic scale on the top surface of the lifting seat, several feeding components on the top of the mounting frame, each feeding component including a storage tank, an upward-opening receiving cylinder on one side wall of the storage tank, two through holes at the bottom of the receiving cylinder, two one-way valves with opposite flow directions arranged in the through holes, one of the one-way valves being connected to the bottom of the storage tank via a connecting pipe, and a discharge pipe on the other one-way valve, an inlet on the top of the mixing tank corresponding to the discharge pipe, a piston block vertically slidably arranged inside the receiving cylinder, and an electric push rod vertically arranged above the receiving cylinder on the side wall of the storage tank, the piston rod of the electric push rod pointing downward and connected to the piston block.

[0006] By adopting the above technical solution, a base, mixing tank, main material pipe, electronic scale, and feeding assembly are set up. The lifting seat slides upward to bring the electronic scale into contact with the bottom of the mixing tank. The main material enters the mixing tank through the main material pipe and main material inlet, and the electronic scale measures the weight of the main material entering the mixing tank. Based on the preset mixing ratio, the required volume of each auxiliary material is determined, and the volume of added auxiliary materials is controlled by the lifting stroke of the piston block driven by an electric push rod. The electric push rod drives the piston block to rise, allowing the auxiliary material in the storage tank to enter the receiving cylinder through the connecting pipe. Subsequently, the piston block is driven to fall, precisely extruding a fixed amount of auxiliary material from the discharge pipe, thereby achieving automated control of the main and auxiliary material mixing ratio. There is no need to adjust the parameters of each ingredient individually; only the mixing ratio needs to be input, making the operation quite convenient.

[0007] Furthermore, the mounting frame includes four support rods circumferentially spaced on the base, with a bottom ring at the upper end of the four support rods, four sliding rods circumferentially spaced on the bottom ring, a top ring at the upper end of the four sliding rods, and a mounting seat on the top ring. The feeding components are all mounted on the mounting seats, and two sliding seats connected to the outer wall of the mixing tank are vertically slidably mounted on each of the four sliding rods.

[0008] By adopting the above technical solution, which includes a support rod, bottom ring, sliding rod, top ring, and sliding seat, the sliding seat at the bottom does not contact the bottom ring during the feeding process of the mixing tank. This ensures that the electronic scale supports the mixing tank to measure the weight of the fed material. After feeding, before the mixing tank needs to be stirred, the lifting seat lowers, causing the sliding seat at the bottom to contact the bottom ring, separating the electronic scale from the bottom of the mixing tank and preventing damage to the electronic scale due to vibration during the stirring process.

[0009] Furthermore, the base is provided with four vertical tubes spaced circumferentially, and a lifting rod is slidably installed vertically inside the vertical tube. The bottom of the lifting seat is connected to the upper ends of the four lifting rods. A cylinder is installed vertically on the base, and the piston rod of the cylinder is upward and connected to the bottom of the lifting seat.

[0010] By adopting the above technical solution, a riser, a lifting rod, and a cylinder are set up. The lifting seat is driven to rise and fall by the cylinder. When the lifting seat rises and falls, the lifting rod slides inside the riser to ensure the stability of the lifting seat.

[0011] Furthermore, the bottom of the mixing tank is connected to a discharge pipe, a solenoid valve is installed on the discharge pipe, a connecting seat is installed at the bottom of the bottom ring, an L-shaped pipe is installed on the connecting seat, and the top end of the vertical section of the L-shaped pipe corresponds to the bottom end of the discharge pipe.

[0012] By adopting the above technical solution, a discharge pipe, an electronic valve, a connecting seat, and an L-shaped pipe are set up. After the ingredients in the mixing tank are mixed into an adhesive, the solenoid valve is opened, and the adhesive in the mixing tank is discharged from the discharge pipe and falls into the L-shaped pipe for delivery. The discharge pipe and the L-shaped pipe do not contact each other and will not interfere with the electronic scale's weight measurement.

[0013] Furthermore, an annular groove is formed on the outer wall of the piston block, and a rubber ring is provided in the annular groove. The outer diameter of the rubber ring is the same as the inner diameter of the receiving cylinder.

[0014] Furthermore, a vertically arranged strip-shaped hole is provided on one side of the storage box, and a glass plate is placed inside the strip-shaped hole.

[0015] By adopting the above technical solution and setting up strip holes and glass plates, staff can intuitively observe the remaining amount of auxiliary materials in the storage box, which facilitates timely replenishment of materials.

[0016] Furthermore, the storage box is hinged to a lid at the top.

[0017] In summary, this utility model has the following beneficial effects: This application includes a base, a mixing tank, a main material pipe, an electronic scale, and a feeding assembly. The lifting seat slides upwards to bring the electronic scale into contact with the bottom of the mixing tank. The main material enters the mixing tank through the main material pipe and main material inlet, and the electronic scale measures the weight of the main material entering the mixing tank. Based on a preset mixing ratio, the required volume of each auxiliary material is determined, and the volume of added auxiliary materials is controlled by the lifting stroke of the piston block driven by an electric push rod. The electric push rod drives the piston block to rise, allowing the auxiliary materials in the storage tank to enter the receiving cylinder through the connecting pipe. Subsequently, the piston block is driven to fall, precisely extruding a measured amount of auxiliary materials from the discharge pipe, thereby achieving automated mixing ratio control of the main and auxiliary materials. It eliminates the need to adjust the parameters of each ingredient individually; only the mixing ratio needs to be input, making operation more convenient. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-5As shown in the illustration, this application discloses an adhesive mixing ratio control device, including a base 10, a mixing tank 30, a main material pipe 21, an electronic scale 41, and a feeding assembly 50. A mounting frame 20 is mounted on the base 10. The mixing tank 30 is vertically slidably mounted within the mounting frame 20. The main material pipe 21 is mounted on the mounting frame 20 and is L-shaped overall, with the lower end of the vertical section of the main material pipe 21 serving as the output end. A main material inlet 31 is located at the top of the mixing tank 30 corresponding to the output end of the main material pipe 21. A lifting seat 40 is vertically slidably mounted on the base 10 below the mixing tank 30, and the electronic scale 41 is mounted on the top surface of the lifting seat 40. The lifting seat 40 slides upwards to bring the electronic scale 41 into contact with the bottom of the mixing tank 30. The main material enters the mixing tank 30 through the main material pipe 21 and the main material inlet 31, and the electronic scale 41 measures the weight of the main material entering the mixing tank 30. The top of the mounting frame 20 is equipped with several feeding components 50, each including a storage tank 51. A receiving cylinder 52 with an upward-facing opening is located on one side wall of the storage tank 51. Two through holes are opened at the bottom of the receiving cylinder 52, each containing two one-way valves 53 with opposite flow-limiting directions. One one-way valve 53 is connected to the bottom of the storage tank 51 via a connecting pipe 54, while the other one-way valve 53 has a discharge pipe 55. A feeding port 56 is located at the top of the mixing tank 30 corresponding to the discharge pipe 55. A piston block 57 is vertically slidably mounted inside the receiving cylinder 52. An electric push rod 58 is vertically mounted on the side wall of the storage tank 51 above the receiving cylinder 52. The piston rod of the electric push rod 58 points downward and connects to the piston block 57. Based on a preset mixing ratio, the required volume of each auxiliary material is determined, and the volume of added auxiliary materials is controlled by the lifting stroke of the piston block 57 driven by the electric push rod 58. The electric push rod 58 drives the piston block 57 to rise, allowing the auxiliary materials in the storage tank 51 to enter the receiving cylinder 52 through the connecting pipe 54. Then, the piston block 57 descends, precisely extruding a measured amount of auxiliary materials from the discharge pipe 55, thus achieving automated proportioning control of the main and auxiliary materials. There is no need to adjust the parameters of each ingredient individually; only the proportion needs to be input, making operation quite convenient.

[0026] Specifically, the one-way valve 53 connected to the connecting pipe 54 only allows auxiliary materials to flow unidirectionally from the connecting pipe 54 into the receiving cylinder 52, and the one-way valve 53 connected to the discharge pipe 55 only allows auxiliary materials to flow unidirectionally from the receiving cylinder 52 to the discharge pipe 55. When the piston block 57 rises, the auxiliary materials in the storage tank 51, under negative pressure, can only enter the receiving cylinder 52 through the one-way valve 53 connected to the connecting pipe 54; when the piston block 57 falls, the auxiliary materials in the receiving cylinder 52, under positive pressure, can only be discharged to the discharge pipe 55 through the one-way valve 53 connected to the discharge pipe 55. This design effectively prevents the backflow or mixing of auxiliary materials, ensuring the accuracy and reliability of the batching process. The bottom of the mixing tank 30 is connected to a discharge pipe 32, and a solenoid valve 33 is installed on the discharge pipe 32. A connecting seat 28 is installed at the bottom of the bottom ring 23, and an L-shaped pipe 29 is installed on the connecting seat 28. The top of the vertical section of the L-shaped pipe 29 corresponds to the bottom of the discharge pipe 32. After the ingredients in the mixing tank 30 are mixed into an adhesive, the solenoid valve 33 is opened, and the adhesive in the mixing tank 30 is discharged from the discharge pipe 32 and falls into the L-shaped pipe 29 to be conveyed out. The discharge pipe 55 does not contact the L-shaped pipe 29 and will not interfere with the electronic scale 41 to measure the weight.

[0027] The piston block 57 has an annular groove 571 on its outer wall, and a rubber ring 572 is installed inside the annular groove 571. The outer diameter of the rubber ring 572 is the same as the inner diameter of the receiving cylinder 52, ensuring the sealing between the piston block 57 and the receiving cylinder 52. A vertically arranged strip hole 511 is provided on one side of the storage box 51, and a glass plate 512 is installed inside the strip hole 511, allowing the staff to visually observe the remaining amount of auxiliary materials in the storage box 51, facilitating timely replenishment. A box cover 513 is hinged to the top of the storage box 51. The staff can add auxiliary materials to the storage box 51 by opening the box cover 513. The box cover 513 has a vent hole to allow outside air to enter the storage box 51. When the auxiliary materials in the storage box 51 flow out, outside air can enter the storage box 51.

[0028] During setup, the mounting frame 20 includes four support rods 22 circumferentially spaced on the base 10. A bottom ring 23 is shared at the upper end of the four support rods 22. Four sliding rods 24 are circumferentially spaced on the bottom ring 23. A top ring 25 is shared at the upper end of the four sliding rods 24. A mounting seat 26 is mounted on the top ring 25. All feeding components 50 are mounted on the mounting seats 26. Two sliding seats 27, connected to the outer wall of the mixing tank 30, are vertically slidably mounted on each of the four sliding rods 24. The sliding rods 24 and support rods 22 are all vertically arranged. During feeding into the mixing tank 30, the lowest sliding seat 27 does not contact the bottom ring 23, ensuring that the electronic scale 41 supports the mixing tank 30 to measure the weight of the fed material. After feeding, before stirring the ingredients inside the mixing tank 30, the lifting seat 40 descends, causing the lowest sliding seat 27 to contact the bottom ring 23, separating the electronic scale 41 from the bottom of the mixing tank 30, thus preventing damage to the electronic scale 41 from vibrations during the mixing process.

[0029] In the specific configuration, the base 10 has four vertical tubes 42 spaced circumferentially. A lifting rod 43 is vertically slidably mounted inside each vertical tube 42. The bottom of the lifting seat 40 is connected to the upper ends of the four lifting rods 43, allowing the lifting seat 40 and the lifting rods 43 to move synchronously. A cylinder 44 is vertically mounted on the base 10. The piston rod of the cylinder 44 points upward and is connected to the bottom of the lifting seat 40. The cylinder 44 drives the lifting seat 40 to rise and fall. When the lifting seat 40 rises and falls, the lifting rods 43 slide within the vertical tubes 42 to ensure the stability of the lifting seat 40's movement.

[0030] The mixing tank 30 includes a tank body and a rotating shaft that is vertically rotatably installed inside the tank body. Several stirring blades are arranged circumferentially on the rotating shaft. The upper end of the rotating shaft passes through the top of the tank body. A drive motor is vertically installed on the top of the tank body. The output shaft of the drive motor is connected to the end of the rotating shaft that passes through the tank body.

[0031] The principle of the adhesive mixing ratio control device in this embodiment is as follows: The cylinder 44 first drives the lifting seat 40 and the electronic scale 41 to rise, lifting the mixing tank 30 and separating the bottom of the mixing tank 30 from the bottom ring 23. Then, the main material enters the mixing tank 30 through the main material pipe 21 and the main material inlet 31. The electronic scale 41 measures the weight of the main material entering the mixing tank 30. Based on the preset mixing ratio, the required volume of each auxiliary material is determined. The volume of the auxiliary material is controlled by the lifting stroke of the piston block 57 driven by the electric push rod 58. The electric push rod 58 is activated to drive the piston block 57 to rise, allowing the auxiliary material in the storage tank 51 to enter the receiving cylinder 52 through the connecting pipe 54. Then, the piston block 57 is driven to descend, precisely extruding a measured amount of auxiliary material from the discharge pipe 55 into the mixing tank 30. Next, the cylinder 44 drives the lifting seat 40 and the electronic scale 41 to descend, bringing the bottom of the mixing tank 30 into contact with the bottom ring 23. There's no need to adjust the parameters for each ingredient individually; you only need to input the ingredient ratio, making it quite convenient to operate.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
