Description

Technical Field

[0001] The utility model relates to the technical field of sealant production, and particularly relates to a material conveying pump for sealant production. Background Technique

[0002] A sealant refers to a sealing material that deforms with the shape of the sealing surface, does not easily flow, and has a certain adhesiveness. It is an adhesive used to fill the configuration gap to play a sealing role. It has functions such as anti-leakage, waterproof, anti-vibration, sound insulation, and heat insulation. In the processing of sealants, a powder conveying pump is required to convey powders.

[0003] At present, a check valve is generally installed at the discharge port of the material conveying pump for sealant production, so that the conveying pump can withstand higher back pressure. However, since the inside of the air box connected to the discharge port of the conveying pump is in a positive pressure state, gas will flow reversely into the conveying pipe during feeding, resulting in unstable discharge, affecting production. Based on this, we propose an improvement to the material conveying pump for sealant production. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a material conveying pump for sealant production, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A material conveying pump for sealant production, including a driving motor, a speed reducer, a blanking pipe, a connecting flange, a conveying pipe, and an air box. One side of the blanking pipe is fixedly connected with a connecting pipe. A conveying shaft is rotatably sleeved inside the blanking pipe. A conveying blade is fixedly sleeved on the outer wall of the conveying shaft. A guiding ring is fixedly sleeved on the inner wall of the conveying pipe near the lower end. A valve plate is rotatably connected to the lower end of the guiding ring. One side of the air box is fixedly connected with a guiding box. A slider is slidably sleeved inside the guiding box. A hinge plate is rotatably connected between the lower end surface of the valve plate and the upper end surface of the slider.

[0007] As a further scheme of the utility model, the output end of the driving motor is fixedly connected with the input end of the speed reducer through a coupling, and the output end of the speed reducer is fixedly connected with one end of the conveying shaft through a coupling.

[0008] As a further scheme of the utility model, connecting flanges are fixedly sleeved on the outer walls of the blanking pipe and the conveying pipe, and the two connecting flanges are fixedly connected by bolts.

[0009] As a further scheme of the utility model, the lower end of the conveying shaft extends into the conveying pipe and is rotatably arranged above the guiding ring, and the opening groove at the upper end of the guiding ring is made of an inverted conical structure.

[0010] As a further solution of the present utility model, an air inlet is provided at one end of the bellows, and a discharge port is provided at the other end of the bellows.

[0011] As a further solution of the present utility model, one end of the guiding box is rotatably sleeved with an adjusting screw rod. A pressing ring is threadedly sleeved on the outer wall of the adjusting screw rod. One end of the adjusting screw rod is fixedly connected with a sliding rod. The sliding block is slidably sleeved on the outer wall of the sliding rod, and a spring is fixedly connected between the sliding block and the pressing ring. One end of the adjusting screw rod penetrates through the side plate of the bellows and is fixedly sleeved with a rotating wheel.

[0012] As a further solution of the present utility model, limiting grooves are provided on the inner walls of both sides of the guiding box. Limiting blocks are slidably connected in the two limiting grooves respectively. The front and rear outer walls of the pressing ring are fixedly connected with the two limiting blocks respectively.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By setting the material guiding ring, valve plate, guiding box, sliding block, sliding rod, spring and hinged plate structures, when the device guides materials, the powder enters the feeding pipe from the connecting pipe, and then the powder is driven by the conveying blades and falls into the material guiding ring. As the powder gradually increases to a certain extent, the hinged plate compresses the sliding block to move, so that the valve plate opens for discharging. After discharging, as the pressure of the valve plate decreases, under the reaction force of the spring, the sliding block will be driven to reset, and then the valve plate will be driven to close by the hinged plate. During this process, the excess powder accumulated in the conveying pipe can form a blockage, so that the air flow cannot reverse and rush up to the upper part of the conveying pipe against the powder, thus avoiding affecting the stability of discharging;

[0015] By driving the pressing ring to move through the adjusting screw rod, and then adjusting the compression amount of the spring, the magnitude of the moving resistance of the sliding block can be adjusted, and the powder storage amount in the conveying pipe during feeding can be adjusted more conveniently, which has practicability.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-4 shown, a material conveying pump for making glue includes a driving motor 1, a reducer 2, a blanking pipe 3, a connecting flange 4, a conveying pipe 7 and an air box 8. A connecting pipe 5 is fixedly connected to one side of the blanking pipe 3. A conveying shaft 11 is rotatably sleeved in the blanking pipe 3. A conveying blade 12 is fixedly sleeved on the outer wall of the conveying shaft 11. A material guiding ring 13 is fixedly sleeved on the inner wall of the conveying pipe 7 near the lower end. A valve plate 14 is rotatably connected to the lower end of the material guiding ring 13. A guiding box 15 is fixedly connected to one side of the air box 8. A slider 18 is slidably sleeved in the guiding box 15. A hinge plate 19 is rotatably connected between the lower end surface of the valve plate 14 and the upper end surface of the slider 18.

[0023] In this embodiment, the output end of the driving motor 1 is fixedly connected to the input end of the reducer 2 through a coupling, and the output end of the reducer 2 is fixedly connected to one end of the conveying shaft 11 through a coupling.

[0024] In this embodiment, connecting flanges 4 are fixedly sleeved on the outer walls of both the blanking pipe 3 and the conveying pipe 7. The two connecting flanges 4 are fixedly connected by bolts. The blanking pipe 3 and the conveying pipe 7 are butted through the connecting flanges 4, which is convenient for later disassembly according to needs to clean the inner walls of the blanking pipe 3 and the conveying pipe 7.

[0025] In this embodiment, the lower end of the conveying shaft 11 extends into the conveying pipe 7 and is rotatably arranged above the material guiding ring 13. The opening groove at the upper end of the material guiding ring 13 is made into an inverted conical structure, which is convenient for guiding materials.

[0026] In this embodiment, an air inlet 9 is opened at one end of the air box 8, and a discharge port 10 is opened at the other end of the air box 8. Air is supplied through the air inlet 9 to drive the powder into the discharge port 10.

[0027] In this embodiment, one end of the guiding box 15 is rotatably sleeved with an adjusting screw rod 16. A pressing ring 20 is threadedly sleeved on the outer wall of the adjusting screw rod 16. One end of the adjusting screw rod 16 is fixedly connected with a sliding rod 17. A slider 18 is slidably sleeved on the outer wall of the sliding rod 17. A spring 21 is fixedly connected between the slider 18 and the pressing ring 20. One end of the adjusting screw rod 16 penetrates through the side plate of the air box 8 and is fixedly sleeved with a rotating wheel. By driving the rotating wheel to drive the adjusting screw rod 16 to rotate, the pressing ring 20 can be driven to move, so as to adjust the compression amount of the spring 21.

[0028] In this embodiment, limiting grooves 6 are formed on the inner walls of both sides of the guiding box 15. Limiting blocks 22 are slidably connected in the two limiting grooves 6 respectively. The front and rear outer walls of the pressing ring 20 are fixedly connected with the two limiting blocks 22 respectively. By sliding the limiting blocks 22 in the limiting grooves 6, the pressing ring 20 can be prevented from rotating according to the rotation of the adjusting screw rod 16.

[0029] It should be noted that the present utility model is a material conveying pump for glue making. When in use, the connecting pipe 5 is externally connected to a powder supply device, and materials are fed into the feeding pipe 3. At the same time, the driving motor 1 is started to drive the conveying shaft 11 to rotate after adjusting the motor speed through the reducer 2, and then drive the conveying blades 12 to rotate to send the materials in the feeding pipe 3 into the conveying pipe 7. As the powder accumulates to a certain extent, the valve plate 14 will be pressed open. At this time, the hinge plate 19 will press the slider 18 to move, thereby compressing the spring 21. The powder falls from the opening of the valve plate 14 and is blown to the discharge port 10 along with the air flow at the air inlet 9. As the powder decreases by a certain amount, under the reaction of the spring 21, the slider 18 will drive the valve plate 14 to close again through the hinge plate 19, so as to prevent too much powder from falling and causing the air flow to reverse and enter the conveying pipe 7;

[0030] In the above process, according to the actual situation, the rotating wheel can be driven to drive the adjusting screw rod 16 to rotate, and then drive the pressing ring 20 to move towards the slider 18 under the limiting action of the limiting block 22. As the compression amount of the spring 21 changes, the sliding resistance of the slider 18 will also increase accordingly, so as to be able to adjust the powder storage amount in the conveying pipe 7 during feeding in turn.

[0031] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
