Description

Technical Field

[0001] The invention belongs to the field of detergent filling, in particular to an automatic detergent filling device and an automatic filling method. Background Art

[0002] Detergent is a product specially formulated for cleaning. It is mainly composed of surfactants, builders and additives. There are many types of detergents, which can be divided into powder, block, paste, slurry and liquid states according to product type.

[0003] Liquid detergents in the prior art are mostly filled in bottles or cans of various shapes, and some detergents are packaged in packaging bags. After the detergent is filled into the packaging bag, the bag opening is heat-sealed by a heat sealing machine to complete the sealed storage of the detergent.

[0004] In the prior art, during the filling process of bagged liquid detergent, some detergent will splash near the bag opening of the packaging bag, causing the bag opening to be wet. When the bag opening is then heat-sealed, the wet bag opening will affect the heat-sealing effect, causing the bag opening to be loosely sealed, resulting in leakage of the detergent in the bag.

[0005] To this end, the present invention provides a detergent automatic filling device and an automatic filling method. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: the automatic detergent filling device described in the present invention comprises a base; a turntable is rotatably connected to the top of the base, and the turntable is driven by a servo motor; a plurality of pairs of evenly arranged connecting plates are fixedly connected to the side surface of the turntable; a plurality of evenly arranged clamping assemblies are installed between the pairs of connecting plates; the clamping assemblies are used to clamp the packaging bag; a support frame is fixedly connected to the top surface of the base on one side of the turntable; a hydraulic rod is fixedly connected to the side of the support frame close to the turntable; a filling bucket is fixedly connected to the telescopic end of the hydraulic rod; a material discharge assembly is fixedly connected to the top surface of the filling bucket; the material discharge assembly is used to inject detergent into the filling bucket; Both sides of the filling bucket are fixedly connected with a support seat; a pair of abutment plates are slidably connected to the surface of the support seat; the ends of the two abutment plates close to each other are wedge-shaped; a pair of springs are fixedly connected between the two abutment plates at the top position; a top plate is arranged between the two abutment plates; the top plate is fixedly connected to the top surface of the connecting plate, and the top surface of the top plate is arranged in an arc shape; a support plate is fixedly connected to the ends of the two abutment plates away from each other; the top plate is located between the pair of springs; a heat sealer is installed on the top surface of the base at a position adjacent to the support frame; the heat sealer is used to heat-seal the top of the packaging bag; when working, when it is necessary to fill the detergent, the embodiment of the present invention can be used, first the top of the base is The turntable on the surface rotates driven by the servo motor, and the packaging bag to be filled is rotated to the bottom of the filling bucket through the clamping assembly. Then the hydraulic rod on the top of the support frame drives the filling bucket to descend, so that the bottom of the filling bucket extends into the packaging bag clamped by the clamping assembly, and the connecting seats on both sides of the filling bucket will also descend with the filling bucket. During the descent of the connecting seat, the two abutment plates on the surface of the connecting seat will squeeze the top plate on the top surface of the connecting plate, so that the two abutment plates move away from each other and stretch the spring. The abutment plates moving away from each other will drive the support plates connected to them to move away from each other, so that the bag mouth of the packaging bag is attached to the surface of the support plate, and then the unloading assembly injects detergent into the filling bucket. Then the detergent is poured into the packaging bag by the filling bucket. At this time, the bag opening is blocked by the support plate, so the splashing detergent will be blocked by the support plate and will not directly adhere to the bag opening of the packaging bag. After the filling is completed, the filling bucket rises under the drive of the hydraulic rod, and the top plate no longer squeezes the back plate. At this time, the stretched spring recovers, thereby driving the back plate and the support plate to approach each other and detach from the packaging bag. After that, the turntable rotates the packaging bag to the heat sealing machine for heat sealing. Since the area near the bag opening of the packaging bag is no longer humid, during the heat sealing process, the bag opening of the packaging bag will not be unevenly heated due to humidity, which will lead to poor heat sealing of the bag opening and cause detergent leakage.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

A support seat 7; a pair of abutment plates 8 are slidably connected to the surface of the support seat 7; the ends of the two abutment plates 8 that are close to each other are wedge-shaped; a pair of springs 9 are fixedly connected between the two abutment plates 8 at the top position; a top plate 10 is arranged between the two abutment plates 8; the top plate 10 is fixedly connected to the top surface of the connecting plate 3, and the top surface of the top plate 10 is arranged in an arc shape; a support plate 11 is fixedly connected to the ends of the two abutment plates 8 that are away from each other; the top plate 10 is located between the pair of springs 9; a heat sealer is installed on the top surface of the base 1 at a position adjacent to the support frame 4; the heat sealer is used to heat-seal the top of the packaging bag; when working, when it is necessary to fill the detergent, the embodiment of the present invention can be used, first, the turntable 2 on the top surface of the base 1 is servo-operated The servo motor rotates, and the packaging bag to be filled is rotated to the bottom of the filling bucket 6 through the clamping assembly. Then the hydraulic rod 5 on the top of the support frame 4 will drive the filling bucket 6 to descend, so that the bottom of the filling bucket 6 is extended into the packaging bag clamped by the clamping assembly, and the connecting seats 12 on both sides of the filling bucket 6 will also descend with the filling bucket 6. During the descent of the connecting seat 12, the two abutment plates 8 on the surface of the connecting seat 12 will squeeze the top plate 10 on the top surface of the connecting plate 3, so that the two abutment plates 8 move away from each other and stretch the spring 9. The abutment plates 8 moving away from each other will drive the support plates 11 fixed thereto to move away from each other, so that the bag mouth of the packaging bag is attached to the surface of the support plates 11, and then the feeding assembly injects washing liquid into the filling bucket 6. The detergent is then poured into the packaging bag by the filling hopper 6. At this time, the bag opening is blocked by the support plate 11, so the splashing detergent will be blocked by the support plate 11 and will not directly adhere to the vicinity of the bag opening of the packaging bag. After the filling is completed, the filling hopper 6 rises under the drive of the hydraulic rod 5, and the top plate 10 no longer squeezes the back plate 8. At this time, the stretched spring 9 recovers, thereby driving the back plate 8 and the support plate 11 to approach each other and separate from the packaging bag. Then the turntable 2 rotates the packaging bag to the heat sealing machine for heat sealing. Since the vicinity of the bag opening of the packaging bag is no longer humid, during the heat sealing process, the bag opening of the packaging bag will not be unevenly heated due to humidity, which will lead to poor heat sealing of the bag opening, causing leakage of detergent.

When the support plate 11 is pushed against the inner wall of the packaging bag, the rotating rod 14, the airbag 15 and the absorbent pad 13 are also pressed against the surface of the packaging bag. During the squeezing process, the airbag 15 will be deformed, thereby increasing the contact area between the absorbent pad 13 and the inner wall of the packaging bag, ensuring that the position of the packaging bag that needs to be heat-sealed can be in a dry state.

[0039] As shown in Figure 6, the thickness of the support plate 20 around is greater than the thickness at the center; a rubber ring 24 is fixedly connected to the edge of the surface of the support plate 20 close to the inner wall of the separator tank 17; the cross-section of the rubber ring 24 is triangular; during operation, when the detergent in the separator tank 17 needs to be discharged, since the thickness of the support plate 20 around is greater than the thickness at the center, the detergent can flow more smoothly to the through hole 21 at the center of the support plate 20, and the rubber ring 24 at the edge of the support plate 20 and the separator tank 17 can also play a sealing role to prevent the detergent from penetrating into the bottom of the separator tank 17 through the gap between the support plate 20 and the inner wall of the separator tank 17, thereby wasting the detergent.

[0040] like Figures 5 and 6 As shown, a pair of connecting rings 25 are fixedly connected at the middle position on the surface of the bellows 22; the connecting rings 25 are symmetrical about the bellows 22; a limiting rod 26 is slidably connected inside the connecting rings 25; the bottom of the limiting rod 26 is slidably connected to the liquid separator 17; during operation, when the support plate 20 rises or falls along the liquid separator 17, the support plate 20 will also drive the top end of the bellows 22 to rise or fall, thereby driving the bellows 22 to compress or stretch, and when the bellows 22 is compressed or stretched, the limiting rod 26 will cooperate with the connecting rings 25 on the surface of the bellows 22 to limit the twisting of the bellows 22, thereby avoiding the bellows 22 from bending during the compression process, which causes the bellows 22 to be blocked, so that the detergent cannot flow smoothly through the bellows 22.

[0041] like Figures 5 and 6As shown, an air pipe 27 is fixedly connected to the top of the separating tank 17; the air pipe 27 is connected to an external air pump; a one-way valve is provided at one end of the air pipe 27 close to the separating tank 17; during operation, when it is necessary to discharge the detergent in the separating tank 17 to the liquid outlet pipe 18, the user pumps gas into the air pipe 27 through an external air pump, and after the gas enters the separating tank 17 through the one-way valve, the detergent in the separating tank 17 will be pressed toward the through hole 21 on the surface of the support plate 20, thereby reducing the residual detergent in the separating tank 17 and ensuring that the detergent in the separating tank 17 can flow out smoothly.

[0042] like Figure 6 to Figure 7 As shown, the locking assembly includes an arc plate 1 28; the arc plate 1 28 is slidably connected to the bottom surface of the liquid separation tank 17, and the surface of the arc plate 1 28 is in contact with the surface of the ejector rod 19; the two ends of the arc plate are connected with an arc plate 29 by bolts; the arc plate 1 28 and the arc plate 29 are respectively located on both sides of the ejector rod 19, and the ejector rod 19 is clamped therebetween; when working, when the user needs to push or pull the ejector rod 19, the user needs to release the bolts connecting the arc plate 1 28 and the arc plate 29, and remove the arc plate 29, and then Then the user can slide the push rod 19 normally. When the push rod 19 moves to the desired position, the user connects the arc plate 29 and the arc plate 1 28 together by bolts, so that the arc plate 1 28 and the arc plate 2 29 cooperate to clamp the push rod 19, and the push rod 19 is fixed by the friction between the arc plates 1 28, the arc plates 2 29 and the push rod 19, thereby controlling the space between the support plate 20 at the end of the push rod 19 and the branch pipe, thereby realizing stepless adjustment of the volume of the liquid separation tank 17 to meet the user's needs for filling packaging bags of different volumes.

[0043] like Figure 8 As shown, an automatic filling method, which uses the above-mentioned automatic detergent filling device, includes the following steps:

[0044] S1. First, the user needs to determine the volume of detergent required to be filled in each packaging bag, and introduce the volume of detergent into the separator tank 17. Then, the user closes the solenoid valve between the separator tank 17, the storage tank 16 and the liquid outlet pipe 18. Then, the user pushes the support plate 20 through the handle 23 and the push rod 19 until the support plate 20 is blocked by the detergent in the separator tank 17 and cannot continue to rise. At this time, the volume in the separator tank 17 is the volume of detergent that the user needs to pour;

[0045] S2, then the robot arm delivers the packaging bag to be filled to the clamping assembly, and the clamping assembly clamps the packaging bag and stretches the packaging bag, and then the turntable 2 rotates the clamping assembly and the stretched packaging bag to the bottom of the filling bucket 6, and then the hydraulic rod 5 lowers the filling bucket 6, so that the filling bucket 6 extends into the packaging bag, and the liquid separation tank 17 introduces the detergent into the filling bucket 6, and then the filling bucket 6 introduces the detergent into the packaging bag, thereby completing the detergent filling operation;

[0046] S3, then the turntable 2 carries the filled packaging bag to the heat sealing machine, and the heat sealing machine completes the heat sealing of the packaging bag mouth, thereby completing the entire filling and packaging operation.

[0047] During operation, when it is necessary to fill detergent, the embodiment of the present invention can be used. First, the turntable 2 on the top surface of the base 1 rotates driven by the servo motor, and the packaging bag to be filled is rotated to the bottom of the filling bucket 6 through the clamping assembly. Then the hydraulic rod 5 on the top of the support frame 4 drives the filling bucket 6 to descend, so that the bottom of the filling bucket 6 extends into the packaging bag clamped by the clamping assembly, and the connecting seats 12 on both sides of the filling bucket 6 will also descend with the filling bucket 6. During the descent of the connecting seat 12, the two abutment plates 8 on the surface of the connecting seat 12 will squeeze the top plate 10 on the top surface of the connecting plate 3, so that the two abutment plates 8 move away from each other and stretch the spring 9. The abutment plates 8 that move away from each other will drive the support plates 11 fixed thereto to move away from each other, so that the surface of the support plates 11 fits the packaging bag. The bag opening, and then the feeding assembly injects detergent into the filling bucket 6, and then the filling bucket 6 pours the detergent into the packaging bag. At this time, the bag opening is blocked by the support plate 11, so the splashing detergent will be blocked by the support plate 11 and will not directly adhere to the bag opening of the packaging bag. After the filling is completed, the filling bucket 6 rises under the drive of the hydraulic rod 5, and the top plate 10 no longer squeezes the push plate 8. At this time, the stretched spring 9 recovers, thereby driving the push plate 8 and the support plate 11 to approach each other and detach from the packaging bag. Then the turntable 2 rotates the packaging bag to the heat sealing machine for heat sealing. Since the area near the bag opening of the packaging bag is no longer humid, during the heat sealing process, the bag opening of the packaging bag will not be unevenly heated due to humidity, which will lead to poor heat sealing of the bag opening, causing leakage of detergent.

[0048] When the support plate 11 moves toward the inner wall of the packaging bag, the support plate 11 will move toward the inner wall of the packaging bag with the connecting seat 12 on its surface, and then the absorbent pad 13 between the connecting seats 12 will be pressed against the surface of the packaging bag, thereby absorbing the detergent at the bag opening of the packaging bag, ensuring the dryness of the bag opening, thereby further ensuring the sealing of the packaging bag during heat sealing.

[0049] When the filling bucket 6 rises and separates from the packaging bag, the connecting seat 12, rotating rod 14, air bag 15 and water absorbent pad 13 on the surface of the filling bucket 6 will also rise accordingly. Then, the rotating rod 14 rotates under the drive of the motor, and drives the air bag 15 and water absorbent pad 13 on its surface to rotate together. The detergent adsorbed by the water absorbent pad 13 is thrown off the water absorbent pad 13 through centrifugal action, thereby ensuring the dryness of the water absorbent pad 13 and the subsequent adsorption capacity of the water absorbent pad 13 for detergent. When the support plate 11 is pushed against the inner wall of the packaging bag, the rotating rod 14, air bag 15 and water absorbent pad 13 will also be pressed against the surface of the packaging bag. During the squeezing process, the air bag 15 will be deformed, thereby increasing the contact area between the water absorbent pad 13 and the inner wall of the packaging bag, ensuring that the position of the packaging bag that needs to be heat sealed can be in a dry state.

[0050] When it is necessary to fill the detergent, the liquid storage tank 16 will first introduce the detergent into the liquid separation tank 17, and after the liquid separation tank 17 is filled, the solenoid valve between the liquid separation tank 17 and the liquid storage tank 16 is closed, so that the liquid storage tank 16 is separated from the liquid separation tank 17, and then the solenoid valve in the liquid outlet pipe 18 is opened, so that the detergent in the liquid separation tank 17 can flow to the liquid outlet pipe 18, and then be guided by the liquid outlet pipe 18 to the filling bucket 6, and finally flow from the filling bucket 6 into the packaging bag, and the volume of the detergent filled each time is ensured to remain unchanged through the volume of the liquid separation tank 17, thereby realizing the quantitative filling of the detergent.

[0051] When the user needs to adjust the filling volume of the detergent, the user can push and pull the push rod 19 through the handle 23, and then the push rod 19 controls the position of the support plate 20 in the separator tank 17, and stretches or compresses the bellows 22 at the through hole 21, thereby controlling the volume between the support plate 20 and the top of the separator tank 17, thereby controlling the volume of the detergent entering the separator tank 17, so as to adjust the volume of the detergent filled into the packaging bag.

[0052] When the detergent in the separator tank 17 needs to be discharged, since the thickness around the support plate 20 is greater than the thickness at the center, the detergent can flow more smoothly to the through hole 21 at the center of the support plate 20. At the same time, the rubber ring 24 at the edge of the support plate 20 and the separator tank 17 can also play a sealing role to prevent the detergent from seeping into the bottom of the separator tank 17 through the gap between the support plate 20 and the inner wall of the separator tank 17, thereby causing waste of detergent.

[0053] When the support plate 20 rises or falls along the liquid separator 17, the support plate 20 will also drive the top end of the bellows 22 to rise or fall, thereby driving the bellows 22 to compress or stretch. When the bellows 22 is compressed or stretched, the limit rod 26 will cooperate with the connecting ring 25 on the surface of the bellows 22 to limit the twisting of the bellows 22, thereby preventing the bellows 22 from bending during the compression process, which will cause the bellows 22 to be blocked, making it impossible for the detergent to flow smoothly through the bellows 22.

[0054] When it is necessary to discharge the detergent in the separator tank 17 to the liquid outlet pipe 18, the user pumps gas into the air pipe 27 through an external air pump. After the gas enters the separator tank 17 through the one-way valve, the detergent in the separator tank 17 is pressed toward the through hole 21 on the surface of the support plate 20, thereby reducing the residual detergent in the separator tank 17 and ensuring that the detergent in the separator tank 17 can flow out smoothly.

[0055] When the user needs to push or pull the push rod 19, the user needs to release the bolts connecting the arc plate 1 28 and the arc plate 29, and remove the arc plate 29. Then the user can slide the push rod 19 normally. When the push rod 19 moves to the desired position, the user connects the arc plate 29 and the arc plate 1 28 together with bolts, so that the arc plate 1 28 and the arc plate 29 cooperate to clamp the push rod 19, and the push rod 19 is fixed by the friction between the arc plate 1 28, the arc plate 29 and the push rod 19, thereby controlling the space between the support plate 20 at the end of the push rod 19 and the branch pipe, thereby realizing stepless adjustment of the volume of the liquid separation tank 17 to meet the user's needs for filling packaging bags of different volumes.
