Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic painting, in particular to a multi-pipe quantitative paint supply and bead running system. BACKGROUND

[0002] In the field of automatic painting, surface painting process plays a crucial role in the appearance and protection of components such as automobile bodies and bumpers. With the continuous development of the automobile industry, higher requirements are placed on the efficiency, quality, and cost control of the painting process. An efficient painting process not only improves the appearance quality of products and enhances their market competitiveness, but also reduces production costs and improves production efficiency to a certain extent. Therefore, developing advanced painting technology and equipment has become an important research direction in this field.

[0003] Traditional paint supply systems often use gear pumps, diaphragm pumps, etc. as power sources to transport paint from storage tanks to spraying robots or guns through pipelines. When frequent color changes are required in production, the traditional pipeline system has a large amount of residual paint inside, which requires a large amount of cleaning solvent and a long downtime during the cleaning process. This not only reduces production efficiency, but also causes a huge waste of paint and solvent, increasing production costs and environmental burden, which needs to be improved. SUMMARY

[0004] In order to reduce the waste of paint and solvent, the present application provides a multi-pipe quantitative paint supply and bead running system.

[0005] The multi-pipe quantitative paint supply and bead running system provided by the present application adopts the following technical solutions: A multi-pipe quantitative paint supply and bead running system, comprising a feeding mechanism, a feeding mechanism, and a spraying mechanism, the feeding mechanism is used to transport paint in the feeding mechanism to the spraying mechanism; the feeding mechanism comprises a feeding pipeline and a first quantitative bead and a second quantitative bead movably installed in the feeding pipeline, the feeding mechanism and the spraying mechanism are installed at both ends of the feeding pipeline; A storage channel is formed between the first quantitative bead and the second quantitative bead, the feeding pipeline is provided with a driving structure and a positioning structure, the driving structure is used to drive the first quantitative bead and the second quantitative bead to slide in the feeding pipeline, and the positioning structure is used to fix the first quantitative bead and the second quantitative bead.

[0006] By adopting the technical scheme, at the initial stage of the system, the first quantitative bead is fixed at one end of the pipeline, the paint supply mechanism injects paint into the storage channel, and the second quantitative bead is driven to move to accommodate the paint; then, the driving structure drives the double quantitative beads as a whole to move to the other end of the pipeline, and the first quantitative bead is fixed again; finally, the second quantitative bead is driven to move alone, and the paint in the storage channel is almost emptied to the spraying mechanism, and the spraying is completed. This way reduces the paint residue and sediment in the pipeline, and reduces the risk of solidification and scaling.

[0007] During color changing or maintenance, the system only needs to inject a small amount of solvent into the emptied storage channel and push the double quantitative beads back to the initial position; this process only cleans the short pipeline wall and the surface of the quantitative beads corresponding to the storage channel, making the cleaning process fast and the solvent consumption low, reducing the cost.

[0008] Optionally, the driving structure is provided with two groups, and the two groups of driving structures are respectively arranged at two ends of the conveying pipeline; the driving structure comprises an air outlet pipe and an air extraction device, and the air outlet pipe is used to connect the conveying pipeline and the air extraction device.

[0009] By adopting the technical scheme, the driving structure at one end applies pressure to the second quantitative bead, and the two quantitative beads are pushed as a whole to the end for spraying. The driving structure at the other end applies pressure to the first quantitative bead, and the two quantitative beads are pushed as a whole back to the initial end; this process can add solvent to empty the residual between the two quantitative beads and prepare for the next cycle.

[0010] Optionally, the conveying pipeline is provided with two air guide rings, and the two air guide rings are located on the sides away from each other of the first quantitative bead and the second quantitative bead; the air guide ring is provided with an air guide opening, and the center of the air guide opening is located away from the center of the air guide ring.

[0011] By adopting the technical scheme, when the air blowing pipe at one side blows air into the conveying pipeline, the high-speed airflow is sprayed from the eccentric air guide opening and impacts the quantitative bead. Since the force of the air on the quantitative bead is away from the center of the quantitative bead, a rotational torque is generated, causing the quantitative bead to rotate quickly; thereby reducing the static friction between the quantitative bead and the conveying pipeline and improving the service life of the quantitative bead.

[0012] Optionally, the air guide ring is rotatably installed on the conveying pipeline, and the conveying pipeline is provided with a rotating assembly for driving the air guide ring to rotate.

[0013] By adopting the technical scheme, the rotation assembly drives the air guide ring to rotate, and the rotating air guide ring no longer blows air to a fixed direction, but instead applies force on the entire circumferential surface of the quantitative walking bead in a circulating and alternating manner. This ensures that the quantitative walking bead is subjected to more uniform force and eliminates local wear or deformation that may be caused by long-term force on a single fixed point.

[0014] Optionally, the rotation assembly comprises an internal gear, an external gear and a plurality of fan blades, the inner wall of the conveying pipeline is provided with a mounting seat, and the air guide ring is rotatably mounted on the mounting seat; the internal gear is fixed with the air guide ring, and the axis of the air guide ring is coaxially arranged with the axis of the internal gear; the external gear is rotatably mounted on the mounting seat through a rotating shaft, the external gear is engaged with the internal gear, and all the fan blades are fixed on the rotating shaft.

[0015] By adopting the technical scheme, the airflow in the conveying pipeline is used as a power source to drive the fan blades to rotate, and then the rotating shaft and the external gear drive the internal gear and the air guide ring. The rotation assembly does not need to be equipped with a motor or other power device to drive the air guide ring, thereby reducing manufacturing cost and energy consumption.

[0016] Optionally, the water conveying pipeline is provided with a connecting seat at both ends, the air outlet pipe is connected with the mounting seat, the connecting seat is provided with a sliding hole, a sliding part is slidably mounted in the sliding hole, one end of the sliding part is connected with the air guide ring, a rotating groove is formed in the inner wall of the sliding hole, a driving gear is rotatably mounted in the rotating groove, and a tooth groove is formed in the outer wall of the sliding part for engaging the driving gear. Both the connecting seats are provided with a pulling groove, one of the air guide rings is fixed with a pulling rope, and the free end of the pulling rope is arranged in the pulling grooves of the two connecting seats and connected with the other air guide ring.

[0017] By adopting the technical scheme, when the high-pressure airflow is blown into the conveying pipeline, the high-pressure airflow can abut against one side of the air guide ring, so that the air guide ring slides in the conveying pipeline. However, due to the cooperation between the gear and the tooth groove in the outer wall of the sliding part, the sliding resistance of the air guide ring is increased. Therefore, the air guide ring can avoid contacting the quantitative walking bead on the same side during the process of the high-pressure airflow entering the conveying pipeline. In addition, the air guide ring and the quantitative walking bead on the same side can move simultaneously, so that the high-speed airflow can be concentrated to blow to the eccentric position of the outer edge of the quantitative walking bead, thereby maintaining the rotation effect of the quantitative walking bead.

[0018] The pulling rope connected with the two air guide rings can drive the other air guide ring to move when one air guide ring moves in a certain direction under the action of the wind force, thereby avoiding the contact between the other air guide ring and the quantitative walking bead on the same side.

[0019] Optionally, the sliding part comprises multiple sliding plates and a hinge installed between two sliding plates, and the sliding plate at the first end is connected with the air guide ring.

[0020] By adopting the technical scheme, when the sliding part needs to be extended outward for work and exposed outside the conveying pipeline, the two sliding plates connected by the hinge are actively bent, so that the sliding part is prevented from being excessively exposed in a long straight line.

[0021] Optionally, the air guide ring is provided with a guide surface away from the first / second quantitative bead side, and the guide surface is used to guide the air to pass through the air guide opening.

[0022] By adopting the technical scheme, the resistance generated by the air blowing through the air guide ring can be reduced, and the air is guided to flow to the air guide opening at a high speed, so that the air flow sprayed from the air guide opening has a higher speed.

[0023] Optionally, the first / second quantitative bead is wrapped with a rubber layer.

[0024] By adopting the technical scheme, the rubber layer can make the quantitative bead tightly abut against the inner wall of the conveying pipeline, so that the quantitative bead is prevented from leaking during movement.

[0025] In summary, the present application has at least one of the following beneficial technical effects: 1. By providing two quantitative beads, the feeding mechanism injects paint into the storage channel, pushes the second quantitative bead to move to accommodate the paint, and uses the driving structure to push the double quantitative beads to move in the pipeline, so that the outer wall of the quantitative bead can scrape the paint on the wall of the conveying pipeline, thereby almost emptying the paint in the storage channel to the spraying mechanism to complete the spraying. When the double quantitative beads are pushed back to the initial position, the solvent is added to the storage channel, so that the short pipeline wall and the surface of the quantitative bead corresponding to the storage channel can be cleaned, the cleaning work becomes fast, the solvent consumption is low, and the cost is reduced. 2. By providing the air guide ring, when the air blowing pipe on one side blows air into the conveying pipeline, the high-speed air flow is sprayed from the eccentric air guide opening and impacts the quantitative bead, so that the rotational torque is generated due to the force of the air away from the center of the quantitative bead, so that the quantitative bead rotates quickly. Thus, the static friction between the quantitative bead and the conveying pipeline is reduced, and the service life of the quantitative bead is improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying Figures 1-9 The present application is further described in detail. Example 1:

[0029] The embodiments of the present application disclose a multi-pipe quantitative paint feeding and bead walking system.

[0030] With reference to Figure 1 A multi-pipe quantitative paint feeding and bead walking system comprises a control mechanism 1, a feeding mechanism 2, a material conveying mechanism 3 and a spraying mechanism 4, wherein the material conveying mechanism 3 and the spraying mechanism 4 are provided in multiple groups, and all the spraying mechanisms 4 are connected with the respective material conveying mechanisms 3; the feeding mechanism 2 is used for conveying paint into the respective material conveying mechanisms 3, and the material conveying mechanism 3 is used for conveying paint to the spraying mechanism 4 connected therewith.

[0031] The paint supply mechanism 2 comprises a paint bucket 21, a paint taking pipe 22, a paint supply pump 23, a filter 24, a flow meter 25 and a plurality of connecting pipes 26. The paint taking pipe 22 is installed at one end of the paint bucket 21, the paint supply pump 23 is used to draw the paint in the paint bucket 21 into the paint taking pipe 22, the filter 24 is used to filter the paint in the paint taking pipe 22, and the flow meter 25 is used to calculate the paint taking amount. All the connecting pipes 26 are connected with the respective paint feeding mechanisms 3, and the ends of the connecting pipes 26 away from the paint feeding pipes 31 are connected with the paint taking pipe 22, so that the paint bucket 21 can supply paint to the plurality of spraying mechanisms 4. In this embodiment, the connecting pipes 26 are provided with valves 27.

[0032] The paint feeding pipe 31 comprises the paint feeding pipe 31 and first and second fixed-volume beads 32 and 33 movably installed in the paint feeding pipe 31. The two ends of the paint feeding pipe 31 are provided with a launching station 34 and a receiving station 35, respectively. The connecting pipes 26 are installed in the paint feeding pipe 31 and are in communication with the launching station 34. The spraying mechanism 4 is installed in the paint feeding pipe 31 and is in communication with the receiving station 35.

[0033] Referring to Figure 2 , the first and second fixed-volume beads 32 and 33 are both installed in the paint feeding pipe 31. The first and second fixed-volume beads 32 and 33 are spherical in shape, and the inner walls of the first and second fixed-volume beads 32 and 33 abut against the outer wall of the paint feeding pipe 31. The first and second fixed-volume beads 32 and 33 form a paint storage channel 36 between them for storing paint. The paint supply mechanism 2 injects paint into the paint storage channel 36 to push the second fixed-volume bead 33 to accommodate the paint.

[0034] The outer walls of the first and second fixed-volume beads 32 and 33 are wrapped with a rubber layer 37. The rubber layer 37 is elastic, wear-resistant and does not react with paint. The fixed-volume beads wrapped with the rubber layer 37 are in interference fit with the paint feeding pipe 31, which increases the sealing property of the first and second fixed-volume beads 32 and 33 in the paint feeding pipe 31.

[0035] The paint feeding pipe 31 is provided with a positioning structure comprising two groups of electromagnetic components. The two groups of electromagnetic components are installed at the launching station 34 and the receiving station 35, respectively. The electromagnetic components at the launching station 34 are used to fix the second fixed-volume bead 33 with the paint feeding pipe 31, and the electromagnetic components at the receiving station 35 are used to fix the first fixed-volume bead 32 with the paint feeding pipe 31. Since the electromagnetic components are prior art, they will not be described here.

[0036] When the second dosing bead 33 is fixed to the feed pipe 31 by the electromagnetic component at the transmitting station 34, the paint is injected into the storage channel 36 by the feeding mechanism 2, and the paint pushes the first dosing bead 32 to accommodate the paint; when the first dosing bead 32 is fixed to the feed pipe 31 by the electromagnetic component at the receiving station 35, the second dosing bead 33 is continuously pushed, and the paint in the storage channel 36 can be squeezed to the spraying mechanism 4.

[0037] The feed pipe 31 is provided with two groups of driving structures 5, and the two groups of driving structures 5 are respectively installed at both ends of the feed pipe 31; the driving structure 5 includes an air outlet pipe and an air extraction device, and the feed pipe 31 is provided with a connecting seat 38 at both ends, and the air outlet pipe is used to connect the connecting seat 38 with the air extraction device; in the embodiment, the air extraction device is set as a fan, and the fan introduces high-pressure gas into the feed pipe 31 through the air outlet pipe; so as to push the first dosing bead 32 and the second dosing bead 33 to move in the feed pipe 31.

[0038] With reference to Figure 1 and Figure 2 In the embodiment, the feed pipe 31 is provided with an injection pipe 311 and a discharge pipe 312, the injection pipe 311 is installed at the receiving station 35 of the feed pipe, and is used to inject the solvent into the storage channel 36; and the discharge pipe 312 is installed at the transmitting station 34 of the feed pipe, and is used to receive the solvent in the storage channel 36.

[0039] The control mechanism 1 is used to control the opening and closing of all switches of the whole system, so as to feed the paint in each feed pipe 31, and spray the paint by using the spraying mechanism 4; since the spraying mechanism 4 is a prior art, it will not be described here.

[0040] The implementation principle of the embodiment 1 of the application is as follows: At the beginning of the system, the first dosing bead 32 is fixed at one end of the pipe, the feeding mechanism 2 injects the paint into the storage channel 36, and pushes the second dosing bead 33 to move to accommodate the paint; then, the driving structure 5 pushes the whole double-bead to move to the other end of the pipe, and fixes the first dosing bead again; finally, the second dosing bead 33 is pushed to move alone, so that the second dosing bead 33 abuts against the first dosing bead 32, and the paint in the storage channel 36 can be almost emptied to the spraying mechanism 4, and the spraying is completed. This mode reduces the paint residue and precipitation in the pipe, and reduces the risk of solidification and scaling.

[0041] When the color is changed or the system is maintained, only a small amount of solvent needs to be injected into the emptied storage channel 36, and the double-bead is pushed back to the initial position; this process only cleans the short pipe wall and the surface of the bead corresponding to the storage channel 36, so that the cleaning work becomes fast, efficient and low in solvent consumption. Embodiment 2:

[0042] The embodiment of the present application discloses a multi-pipe quantitative paint supply and bead running system.

[0043] With reference to Figure 3 The embodiment 2 of the present application is different from the embodiment 1 in that two groups of air guide rings 6 are arranged in the material conveying pipeline 31, and the two groups of air guide rings 6 are located on the sides away from each other of the first quantitative bead runner 32 and the second quantitative bead runner 33.

[0044] The air guide ring 6 is fixed to the end of the material conveying pipeline 31, and the air guide ring 6 is provided with an air guide hole 61, and the axis of the air guide hole 61 is eccentric to the axis of the air guide ring 6.

[0045] The embodiment principle of the embodiment 2 of the present application is as follows: When the air blowing pipe on one side blows air into the material conveying pipeline 31, the high-speed airflow is sprayed from the eccentric air guide hole and impacts the quantitative bead runner, and since the force of the air on the quantitative bead runner is away from the center of the bead runner, a rotating torque can be generated, so that the quantitative bead runner rotates rapidly; in this way, the static friction between the quantitative bead runner and the conveying pipeline can be reduced, and the service life of the quantitative bead runner can be improved. Embodiment 3:

[0046] The embodiment of the present application discloses a multi-pipe quantitative paint supply and bead running system.

[0047] With reference to Figure 4 The embodiment 3 of the present application is different from the embodiment 2 in that a mounting seat 63 is arranged on the inner wall of the conveying pipeline, and the air guide ring 6 is rotatably mounted on the mounting seat 63; and the mounting seat 63 is provided with a rotating assembly 7, and the rotating assembly 7 is used for driving the air guide ring 6 to rotate.

[0048] With reference to Figure 5 The rotating assembly 7 comprises an internal gear 71, an external gear 72 and a fan blade 73, the internal gear 71 is fixed to the side of the air guide ring 6 away from the quantitative bead runner, and the axis of the internal gear 71 is coaxially arranged with the axis of the air guide ring 6; the mounting seat 63 is provided with a rotating seat 64, the external gear 72 is rotatably mounted on the rotating seat 64 through a rotating shaft 74, and the internal gear 71 and the external gear 72 are engaged.

[0049] The fan blade 73 is provided with a plurality of groups, and all the fan blades 73 are fixed to the outer wall of the rotating shaft 74; when the airflow flows in the conveying pipeline, the airflow drives the fan blade 73 to rotate, the fan blade 73 drives the rotating shaft 74 to rotate, the rotating shaft 74 drives the external gear 72 to rotate, and the external gear 72 drives the internal gear 71 to rotate, so that the air guide ring 6 rotates.

[0050] The implementation principle of the embodiment 3 of the present application is as follows: The air flow in the conveying pipeline is used as a power source to push the fan blades 73 to rotate, and further push the air guide ring 6; the rotating air guide ring 6 makes the air outlet that is out of position no longer fixedly blow air in a certain direction; instead, the air outlet cyclically and alternately exerts force on the entire circumferential surface of the bead. This ensures that the force on the bead is more uniform, and eliminates local wear or deformation that may be caused by long-term force on a single fixed point. Embodiment 4:

[0051] The embodiment of the present application discloses a multi-pipe quantitative paint supply and bead running system.

[0052] With reference to Figure 6 , the embodiment 4 of the present application is different from the embodiment 2 in that the air guide ring 6 is slidingly installed in the conveying pipeline 31, the connecting seat 38 is provided with a sliding hole 631, and the sliding part 8 is slidingly installed in the sliding hole 631, and one end of the sliding part 8 is fixed with the air guide ring 6.

[0053] The sliding part 8 includes multiple sliding plates 81 and a hinge 82 installed between the two sliding plates 81, and the sliding plate 81 at the first end is connected with the air guide ring 6. When the air guide ring 6 moves towards one side of the connecting seat 38, the sliding part 8 protrudes out of the outside; at this time, the two sliding plates 81 connected by the hinge 82 are actively bent, so as to avoid the sliding part 8 from excessively protruding out in a long straight line.

[0054] With reference to Figure 7 , the inner wall of the sliding hole 631 is provided with a rotating groove 632, and the driving gear 84 is rotatably installed in the rotating groove 632; the outer wall of all the sliding plates 81 is provided with a tooth groove 83 engaged with the driving gear 84; when the air guide ring 6 moves away from one side of the connecting seat 38 under the blowing of the high-pressure airflow, the engagement of the driving gear 84 and the tooth groove 83 can increase the sliding resistance of the air guide ring 6; and the engagement avoids the situation that the air guide ring 6 abuts against the quantitative bead after the high-pressure airflow is blown into the conveying pipeline 31.

[0055] With reference to Figure 8 , in the embodiment, one end of the driving gear 84 is fixed with a mounting rod 85, the mounting rod 85 is provided through the connecting seat 38 and protrudes out of the outside, the outer wall of the mounting rod 85 is provided with a threaded portion 86, and the outer wall of the mounting rod 85 is sleeved with a nut 87 for threadedly cooperating with the threaded portion 86; the outer wall of the connecting seat 38 is integrally formed with an abutting portion 39, a rubber ring 88 is sleeved on the outer wall of the mounting rod 85, and the rubber ring 88 is clamped between the outer wall of the nut 87 and the abutting portion 39. The setting of the rubber ring 88 can increase the rotating resistance of the driving gear 84, and further reduce the situation that the air guide ring 6 abuts against the quantitative bead under the driving of the high-pressure airflow.

[0056] It should be noted that when the first quantitative bead 32 is fixed to the material conveying pipeline 31 by the electromagnetic component, the air guide ring 6 on the same side as the first quantitative bead 32 abuts against the connecting seat 38.

[0057] With reference to Figure 9 The two connecting seats 38 are provided with pull grooves 633, one of the air guide rings 6 is fixed with a pull rope 65, the pull rope 65 is connected with the other air guide ring 6 by being arranged in the pull grooves 633 of the two connecting seats 38. When one of the air guide rings 6 moves under the action of the high-pressure airflow, the other air guide ring 6 moves under the action of the pull rope 65, so that the other air guide ring 6 does not abut against the quantitative bead on the same side.

[0058] In order to increase the smoothness of the pull rope 65 sliding in the pull groove 633, the connecting seat 38 is rotatably provided with a reversing roller 66, and the pull rope 65 cooperates with the reversing roller 66.

[0059] The implementation principle of the embodiment 4 of the application is as follows: When the high-pressure airflow blows into the material conveying pipeline 31, the high-pressure airflow can abut against one side of the air guide ring 6, so that the air guide ring 6 slides in the material conveying pipeline 31. However, due to the cooperation between the driving gear 84 and the tooth groove 83 on the outer wall of the sliding part 8, the sliding resistance of the air guide ring 6 is increased. Therefore, the air guide ring 6 can avoid contacting the quantitative bead on the same side during the process of the high-pressure airflow entering the material conveying pipeline 31, and the air guide ring 6 and the quantitative bead on the same side can move simultaneously, so that the high-speed airflow can be concentrated to blow to the eccentric position of the outer edge of the quantitative bead, thereby maintaining the rotation effect of the quantitative bead.

[0060] The above is the preferred embodiment of the application, which does not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
