Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a glue dispensing equipment for adhesive production. Background Technique

[0002] An adhesive is a substance with good adhesion performance, which connects objects by surface adhesion through adhesion and cohesion. It is usually in a viscous liquid shape. During the production process, a glue dispensing equipment is used to dispense it into plastic packaging bottles in specified amounts.

[0003] In order to achieve the purpose of quantitative dispensing, the prior art controls the opening time of the injection tube through a solenoid valve to ensure that an equal amount of glue is injected into each plastic bottle. However, since the glue is viscous and requires a certain pressure during injection, it is likely to cause different amounts of glue dispensed into different plastic bottles, and even glue overflow may occur. Therefore, we propose a glue dispensing equipment for adhesive production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a glue dispensing equipment for adhesive production. By arranging a liftable contact plate on the outer circle of each injection tube, which extends into the plastic bottle together with the injection tube. When the plastic bottle is filled with glue, it will push the contact plate upward to raise its height, and it is detected by the Hall sensor cooperating with the iron sheet. At this time, the solenoid valve is closed to stop injecting glue, ensuring that an equal amount of glue is filled into the plastic bottle and avoiding overflow, thus solving the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A glue dispensing equipment for adhesive production, including a base and an upper plate. The upper plate is supported directly above the base by columns at the four corners of its bottom. In the middle position of the upper surface of the upper plate, there is a material box. Vertically installed on the upper surface of the upper plate outside the material box is an electric push rod. The extending end of the electric push rod penetrates below the upper plate, and a lifting plate is horizontally fixed at the end of the electric push rod. A plurality of injection tubes are evenly arranged on the surface of the lifting plate. The injection tubes penetrate above the lifting plate, and the injection tubes are connected to the inside of the material box through hoses. Below the injection tubes on the lower side of the lifting plate, a solenoid valve communicating with the injection tubes is installed. A ring plate is fixedly surrounded on the outer circle of the injection tube below the solenoid valve. Below the ring plate, there is a contact plate slidably sleeved on the outer circle of the injection tube.

The top of the connecting rod is fixed with a limiting plate abutting against the upper surface of the ring plate. On both sides of the contact plate near the middle position, there are fixed iron sheets, and Hall sensors are fixed on the surface of the ring plate directly above the iron sheets.

[0006] By adopting the above technical solution, the glue solution is placed in the material box. After the electromagnetic valve of the glue injection pipe is opened, the glue solution is injected into the plastic bottle from the glue injection pipe by means of pressurization. When the plastic bottle is filled with the glue solution, it will push up the contact plate and cause it to rise in height, which is detected by the cooperation of the Hall sensor and the iron sheet. Then, the electromagnetic valve is closed in time to achieve the purpose of filling equal amounts of glue solution and avoiding overflow.

[0007] Optionally, a booster pump is installed on the surface of the upper plate on the side of the material box, and the output end of the booster pump is connected to the upper inner part of the material box through a conduit.

Detailed implementation manners

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution: a glue dispensing device for the production of adhesives, including a base 1 and an upper plate 2. The upper plate 2 is supported by support pillars 11 at the four corners of its bottom and placed directly above the base 1. The support pillars 11 at the four corners have the same height, so that the upper plate 2 is placed parallel to the base 1. In the middle of the surface of the upper plate 2, there is a material tank 4. In the middle of the surface of the material tank 4, there is a feed inlet 42. The glue to be dispensed is added into the interior of the material tank 4 through the feed inlet 42. Then, a sealing cover is connected to the upper part of the feed inlet 42 in a screwed manner to seal the feed inlet 42.

[0023] On the surface of the upper plate 2 outside the material tank 4, electric push rods 31 are vertically installed. The extending end of each electric push rod 31 penetrates below the upper plate 2, and a lifting plate 3 is horizontally fixed at the end of the electric push rod 31. The lifting plate 3 is parallel to the base 1 and the upper plate 2, and a plurality of glue injection tubes 5 are evenly arranged on the bottom surface of the lifting plate 3. The upper part of the glue injection tube 5 penetrates above the lifting plate 3, and the glue injection tube 5 is connected to the interior of the material tank 4 through a hose. A limit groove 12 is opened on the surface of the base 1, and the limit groove 12 is located in the middle of the surface of the base 1. Plastic bottles can be quickly aligned and placed through the limit groove 12, or after the plastic bottles are placed in a tray and then placed in the limit groove 12, ensuring that each plastic bottle is aligned below the corresponding glue injection tube 5. A solenoid valve 53 connected to it is installed above the glue injection tube 5 below the lifting plate 3. When the lifting plate 3 drives the glue injection tube 5 to lower to the plastic bottle, the solenoid valve 53 is opened to inject glue into the plastic bottle.

[0024] Since the glue has a large viscosity, in order to ensure that the glue can be smoothly discharged from the glue injection tube 5, a booster pump 41 is installed on the surface of the upper plate 2 on the side of the material box 4. The output end of the booster pump 41 is connected to the upper interior of the material box 4 through a conduit 411. The booster pump 41 will be started first before the solenoid valve 53 is opened, pressurizing the interior of the material box 4 so that the glue can be discharged from the glue injection tube 5 more smoothly.

[0025] In order to ensure that each plastic bottle is filled with an equal amount of glue and prevent the glue from overflowing, a ring plate 51 is fixedly wound around the outer circle of the glue injection tube 5 below the solenoid valve 53. A contact plate 52 is arranged below the ring plate 51 and is slidably sleeved on the outer circle of the glue injection tube 5. A through hole is arranged in the middle of the surface of the contact plate 52, and the glue injection tube 5 passes through the contact plate 52 through the through hole. On both sides of the contact plate 52, connecting rods 522 are vertically fixed and can slide through to the upper part of the ring plate 51. Through holes are arranged on the surface of the ring plate 51 at the position of the connecting rods 522, and the connecting rods 522 pass through the ring plate 51 through the through holes. The top of the connecting rod 522 is fixed with a limiting plate 523 that abuts against the upper surface of the ring plate 51. On both sides of the contact plate 52 near the middle position, iron sheets 521 are fixed. A Hall sensor 511 is fixed on the surface of the ring plate 51 directly above the iron sheet 521. When the glue injection tube 5 descends and extends into the plastic bottle, the contact plate 52 will also enter the plastic bottle, while the ring plate 51 is placed above the plastic bottle. When the glue fills the plastic bottle and overflows to the position below the contact plate 52, it will push up the contact plate 52 to raise its height. When the contact plate 52 raises its height, the iron sheet 521 on its surface will approach the Hall sensor 511 and be detected, and it can be judged that the plastic bottle has been filled with glue. At this time, the solenoid valve 53 corresponding to the glue injection tube 5 above it is controlled to close, so that each plastic bottle can be filled with an equal amount of glue and the glue can be prevented from overflowing.

[0026] During use, unscrew the sealing cap of the feed inlet 42, put the adhesive to be sub-packaged into the material box 4, and then screw on the sealing cap. Place the plastic bottles for sub-packaging neatly in the limiting grooves 12 on the surface of the base 1, or neatly place them in a tray and then place the tray in the limiting grooves 12. Each plastic bottle is placed directly below the glue injection tube 5. When performing the glue dispensing operation, the electric push rod 31 first drives the lifting plate 3 to lower the height, and drives the glue injection tube 5 to also lower the height, so that the annular plate 51 descends to above the plastic bottle, and the bottom of the glue injection tube 5 and the contact plate 52 both extend into the plastic bottle. In the initial state, the contact plate 52 is placed below under the action of gravity, and the limiting plate 523 supports on the surface of the annular plate 51. Subsequently, start the booster pump 41 to pressurize the inside of the material box 4 through the conduit 411, and at the same time open the solenoid valve 53 so that the glue liquid is injected into the plastic bottle from the glue injection tube 5 under the action of pressure until the plastic bottle is filled with glue liquid and overflows to the position below the contact plate 52 and pushes the contact plate 52 upward. When the contact plate 52 rises in height, the iron sheet 521 on its surface will approach the Hall sensor 511 and be detected, indicating that the plastic bottle has been filled with glue liquid. At this time, control the solenoid valve 53 of the corresponding glue injection tube 5 above it to close, so that each plastic bottle can be filled with an equal amount of glue liquid, and at the same time prevent the glue liquid from overflowing.
