Description

Technical Field

[0001] The utility model relates to the technical field of glue coating ratio, in particular to a two-component ratio metering glue coating device. Background Art

[0002] A glue coating machine is an automatic or semi-automatic mechanical device used to evenly coat adhesives on the surfaces of various materials.

[0003] Glue coating machines are widely used in wood, furniture, building materials, packaging, printing, automobiles and other manufacturing industries to improve production efficiency and the consistency of glue coating. At the same time, glue coating machines can use different technologies for glue coating, such as roller glue coating, spray gun glue coating, brush glue coating, etc. The appropriate glue coating method is selected according to the amount of glue coating and the type of material. These machines usually consist of a control system, a conveying system, a glue coating system, a drying system, etc. to ensure precise and efficient operation.

[0004] However, before the glue coating machine performs glue coating, the glue needs to be mixed. Since the glue requires two-component ratio and mixing into glue, the ratio of the two different materials is controlled manually. Not only is it easy to cause incorrect ratio due to mistakes, affecting the normal viscosity of the glue, but also the glue itself is viscous. Before formal stirring and mixing, manual pre-stirring of the two materials is required to make the two materials fully mixed. After full mixing, the formal stirring and mixing equipment rotates the materials at high speed to form viscosity. And manual pre-stirring and mixing increases the labor intensity of the operator. In view of this, a two-component ratio metering glue coating device is provided to overcome the above defects. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art and propose a two-component ratio metering glue coating device.

[0006] To achieve the above object, the utility model adopts the following technical solution: A two-component proportioning and metering glue coating device, including an operation table, on the top left side of the operation table, there are fixedly connected an A-group glue delivery pump and a B-group glue delivery pump. The input end of the A-group glue delivery pump is fixedly connected with an A-group material storage tank, and the input end of the B-group glue delivery pump is fixedly connected with a B-group material storage tank. The output end of the A-group glue delivery pump is fixedly connected with an A-group material delivery pipe, and the output end of the B-group glue delivery pump is fixedly connected with a B-group material delivery pipe. The other ends of the A-group material delivery pipe and the B-group material delivery pipe are fixedly connected with a hollow shell. Inside the hollow shell, there is fixedly connected a first partition on the front side, and a second partition is fixedly connected on the rear side. From the front top end inside the hollow shell to the front end face of the first partition, there is an A-group material bin, and from the rear top end inside the hollow shell to the rear end face of the second partition, there is a B-group material bin. In the lower left corner of the first partition and the second partition, there is fixedly connected a one-way valve. In the middle of the bottom of the hollow shell, there is fixedly connected a motor, and the output end of the motor is fixedly connected with a frame-type stirring blade. From the rear end face of the first partition to the front end face of the second partition, there is a mixing bin. In the middle above the inside of the hollow shell, there is fixedly connected a plunger pump, and the output end of the plunger pump is fixedly connected with a glue delivery pipe. On the top right side of the operation table, there is fixedly connected a frame, and inside the frame, there is fixedly connected a glue coater above.

[0007] As a further description of the above technical solution: Both the front and rear sides of the lower left corner inside the hollow shell are fixedly connected to the left side of the one-way valve. The outer bottom of the frame-type stirring blade contacts the middle lower part inside the hollow shell. The middle above the inside of the hollow shell is fixedly connected to the outer side below the glue delivery pipe. It can transport the materials stored in the A-group material storage tank and the B-group material storage tank to the A-group material bin and the B-group material bin inside the hollow shell for stirring, avoiding the situation that the glue needs to be pre-stirred before mixing, reducing the time and floor area required for pre-stirring the glue, and improving the efficiency of mixing the raw materials into glue.

[0008] As a further description of the above technical solution: Both the A-group glue delivery pump and the B-group glue delivery pump are metering pumps that can quantitatively transport, and both the A-group glue delivery pump and the B-group glue delivery pump are controlled by a PLC control console. According to the different material ratios in the A-group material storage tank and the B-group material storage tank, the flow rates of the A-group glue delivery pump and the B-group glue delivery pump can be controlled by the PLC control console.

[0009] As a further description of the above technical solution: The one-way valve in the lower left corner of the first partition flows from front to back, and the one-way valve in the lower left corner of the second partition flows from back to front. It can allow the A-group material entering the A-group material bin and the B-group material entering the B-group material bin to enter the mixing bin through the one-way valve. The one-way valve can prevent the A-group material and the B-group material from entering the mixing bin simultaneously and causing overflow.

[0010] As a further description of the above technical solution: a horizontal baffle is provided at the bottom of the plunger pump, and the area of the horizontal baffle is the same as the horizontal area of the mixing bin. The edge of the horizontal baffle is fixed above the rear end face of the first partition and above the front end face of the second partition. The horizontal baffle not only serves as the bottom fixation of the plunger pump, but also longitudinally blocks the glue in the mixing bin to prevent the glue from contacting the surface of the plunger pump.

The top of the frame-type stirring blade is connected to the inner ring of the fixed shaft, and the outer ring of the fixed shaft is fixed at the middle position of the bottom of the horizontal baffle provided at the bottom of the plunger pump. The edge of the horizontal baffle is fixed at the rear end face of the first partition and the front end face of the second partition, which can limit the glue in the mixing bin while allowing the top of the frame-type stirring blade to be limited, improving the overall stability of the frame-type stirring blade.

[0012] As a further description of the above technical solution: the glue delivery pipe is a bendable transparent hose, and the total length of the glue delivery pipe is twice the length from the top of the hollow shell to the top of the glue applicator. The length is twice the length from the top of the hollow shell to the top of the glue applicator, which can prevent the glue delivery pipe from detaching from the glue applicator due to insufficient length when the glue applicator slides up and down.

[0013] The utility model has the following beneficial effects:

[0014] The two-component ratio metering glue application equipment designed by the utility model, through design cooperation, enables the device to transport the materials stored in the A-group material storage tank and the B-group material storage tank to the A-group material bin and the B-group material bin inside the hollow shell. The one-way valves leading to the mixing bin transport the A-group material and the B-group material to the mixing bin for mixing to form glue, which is then transported to the glue applicator by the plunger pump, avoiding the need for pre-stirring the glue before mixing, reducing the time and floor area required for pre-stirring the glue, improving the efficiency of mixing the glue from raw materials, and a frame-type stirring blade is provided in the mixing bin where the glue is mixed. The frame-type stirring blade can stir in all directions in the mixing bin, avoiding the situation where only the AB two groups of materials at the bottom of the mixing bin are stirred and mixed when using an ordinary stirring blade, and improving the mixing uniformity of the AB two groups of materials to a certain extent.

The output shaft at the output end of the motor 19 is welded to the middle bottom of the frame-type stirring blade 20 at the top. A mixing bin 17 is opened from the rear end face of the first partition 12 to the front end face of the second partition 13. A plunger pump 18 is fixedly connected to the middle of the upper part inside the hollow shell 8 by bolts. A glue delivery pipe 11 is arranged at the output end of the plunger pump 18. A frame 9 is welded to the right side of the top of the operating platform 1. A glue applicator 10 is fixedly connected to the upper part inside the frame 9 by bolts. Both the front and rear sides of the lower left corner inside the hollow shell 8 are fixedly connected to the left side of the check valve 16. The outer side of the bottom of the frame-type stirring blade 20 is in contact with the middle lower part inside the hollow shell 8.

[0022] As a further implementation of the above technical solution: The glue delivery pumps of Group A 2 and the glue delivery pumps of Group B 3 are both metering pumps capable of quantitative delivery, and the glue delivery pumps of Group A 2 and the glue delivery pumps of Group B 3 are both controlled by a PLC console.

This enables the Group A materials entering the Group A material bin 14 and the Group B materials entering the Group B material bin 15 to enter the mixing bin 17 through the one-way valve 16.

[0024] As a further implementation of the above technical solution: A horizontal baffle is provided at the bottom of the plunger pump 18, and the area of the horizontal baffle is the same as the horizontal area of the mixing bin 17. The edge of the horizontal baffle is fixed above the rear end face of the first partition 12 and above the front end face of the second partition 13. The horizontal baffle not only serves as the bottom fixation of the plunger pump 18 but also longitudinally blocks the glue in the mixing bin 17 to prevent the glue from coming into contact with the surface of the plunger pump 18.

At the same time, the model of the glue applicator 10 is MH6113A. The internal structures and usage methods of these two common devices have not been changed in this application, so this application will not describe them in detail.

[0028] Working principle:

[0029] When using the present utility model, inject the materials in Group A into the storage tank 4 for materials in Group A at the top of the operation table 1, and inject the materials in Group B into the storage tank 5 for materials in Group B. After injection, control the conveying flow rates of the glue conveying pump 2 for Group A and the glue conveying pump 3 for Group B through the PLC console. The glue conveying pump 2 for Group A and the glue conveying pump 3 for Group B pump out the materials in Group A and Group B in the storage tank 4 for materials in Group A and the storage tank 5 for materials in Group B, and inject them into the material bin 14 for Group A and the material bin 15 for Group B in the hollow shell 8 through the material conveying pipe 6 for Group A and the material conveying pipe 7 for Group B.

Turn on the motor 19 at the bottom of the hollow shell 8. The motor 19 drives the frame-type stirring blade 20 through the output shaft at the output end to pre-stir and mix the materials in Group A and Group B entering the mixing bin 17. The materials in Group A and Group B form glue after being fully stirred and mixed. At this time, turn on the plunger pump 18. The plunger pump 18 pumps out the mixed glue from the top of the mixing bin 17, and injects the glue into the glue applicator 10 at the top of the frame 9 through the glue conveying pipe 11 at the output end of the plunger pump 18. The glue applicator 10 performs glue application operations on equipment or objects by spraying glue.
