Description

Technical Field

[0001] This utility model relates to the technical field of waterproof coating filling equipment, specifically to an anti-drip filling pipe for coating filling. Background Technology

[0002] In the field of waterproof coating production and filling, the core requirement of coating filling is not only to achieve quantitative delivery, but also to solve the problem of dripping at the moment of material stoppage. This problem is directly related to product quality stability, production economy and cleanliness of the working environment.

[0003] Currently, anti-drip structures are usually installed on the discharge pipe to address this problem. For example, Chinese utility model patent with patent publication number CN222846448U discloses an anti-drip device for a filling head used in paint production. This anti-drip device is equipped with a discharge pipe, a rotating shaft on one side of the discharge pipe, and a baffle on one end of the rotating shaft. The rotating shaft is driven by a motor to rotate the baffle to the bottom outlet of the discharge pipe, thereby achieving the purpose of preventing dripping.

[0004] However, in actual operation, after the pumping equipment stops pumping, the rotating baffle blocks the discharge pipe. At this time, some paint remains in the discharge pipe. When the baffle moves away from the discharge pipe, the remaining paint flows down with gravity and sticks to the baffle. This not only wastes paint, but also risks causing paint to fall from the baffle and pollute the working environment. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an anti-drip filling pipe for paint filling, which solves the technical problem that residual paint in the discharge pipe in the prior art leads to paint waste and easy pollution of the working environment.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a drip-proof filling tube for paint filling, which includes a filling tube, a piston, a lifting component, a driving component, and a sliding baffle. The filling tube is arranged vertically, and a feed tube is provided through one side of the filling tube. The piston is slidably disposed inside the feed tube. The piston is used to block the feed tube and empty the paint inside the filling tube. The lifting component is disposed at the top of the filling tube and connected to the top of the piston. The driving component is disposed on one side of the top of the filling tube and is used to drive the lifting component to move the piston upward or downward. The sliding baffle is disposed on the outer side of the bottom of the filling tube and is used to scrape off residual paint at the bottom of the filling tube.

[0008] In the above embodiments, a filling tube and a feeding tube are provided, with a piston slidingly installed inside the filling tube. A lifting component and a sliding baffle are respectively installed at the top and bottom of the filling tube. Specifically, the filling tube is aligned with the paint bucket to be filled, and the paint is fed into the filling tube through the feeding tube. After a certain amount of paint is injected into the paint bucket, the driving component is activated. The driving component drives the lifting component to move the piston downward inside the filling tube. The downward movement of the piston will block the feeding tube, thereby stopping the feeding. At the same time, the piston continues to move downward until it is flush with the bottom of the filling tube, so that there is no residual paint in the filling tube. At this time, the sliding baffle can slide to the bottom of the filling tube to scrape off the residual material at the bottom of the filling tube. After replacing the new bucket, the above components are returned to their positions to continue operation.

[0009] In some embodiments, the side of the piston is adapted to the port of the feed tube, a support plate for mounting the drive is fixedly sleeved on the outer side of the top of the filling tube, and the sliding baffle is adapted to the bottom of the filling tube and the piston.

[0010] In some embodiments, limit sliders are fixedly provided on both opposite sides of the top of the piston, and grooves adapted to the limit sliders are opened on both opposite sides of the inner wall of the filling tube, with pressure relief holes opened in the two grooves.

[0011] In some embodiments, the lifting component includes a screw sleeve rotatably mounted inside the top end of the filling tube and a screw rod threadedly connected to the inner wall of the screw sleeve. The bottom end of the screw rod is fixedly connected to the top of the piston, and the outer side of the screw sleeve is connected to the driving component.

[0012] In some embodiments, the driving component includes a motor fixedly mounted on the top of the support plate and a main bevel gear fixedly mounted on the output shaft of the motor, and a driven bevel gear meshing with the main bevel gear is fixedly sleeved on the outside of the threaded sleeve.

[0013] In some embodiments, an N-shaped lifting rod is fixedly connected to the top of the screw, and sliding sleeves for sliding baffles are fixedly provided at both ends of the bottom of the lifting rod. A miniature cylinder fixedly connected to the bottom of the sliding baffle is fixedly provided between the opposite ends of the two sliding sleeves away from the feed pipe.

[0014] In some embodiments, the bottom surface of the filling tube and the bottom surface of the piston are both inclined cross-sections, and the top of the sliding baffle is adapted to the inclined cross-section of the piston.

[0015] Compared with the prior art, this utility model has the following beneficial effects: by adopting the method of using a lifting component to drive the piston to stop the material and scrape the material, it solves the technical problem of paint waste caused by residual paint in the feeding pipe and easy pollution of the working environment, thereby achieving the technical effect of saving paint and avoiding pollution of the working environment.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In an exemplary implementation, such as Figures 1-5As shown, this embodiment provides a drip-proof filling tube for paint filling, including a filling tube 100, a piston 200, a lifting component 300, a driving component 400, and a sliding baffle 500. The filling tube 100 is arranged vertically, and a feeding tube 110 is provided through one side of the filling tube 100. The piston 200 is slidably disposed inside the feeding tube 100. The piston 200 is used to block the feeding tube 110 and empty the paint inside the filling tube 100. The lifting component 300 is disposed at the top of the filling tube 100 and connected to the top of the piston 200. The driving component 400 is disposed on one side of the top of the filling tube 100 and is used to drive the lifting component 300 to move the piston 200 up or down. The sliding baffle 500 is disposed on the outer side of the bottom of the filling tube 100 and is used to scrape off residual paint at the bottom of the filling tube 100.

[0025] In this embodiment, the filling tube 100 is aligned with the paint bucket to be filled. One end of the feeding tube 110 is connected to the feeding device, and the other end is connected to the filling tube 100. The paint can then be fed into the filling tube 100 through the feeding tube 110. After a certain amount of paint is injected into the paint bucket, the drive component 400 is activated. The drive component 400 drives the lifting component 300 to move the piston 200 downward inside the filling tube 100. The downward movement of the piston 200 will block the feeding tube 110, thereby stopping the feeding. At the same time, the piston 200 continues to move downward until it is flush with the bottom of the filling tube 100, so that there is no residual paint in the filling tube 100. At this time, the sliding baffle 500 can slide to the bottom of the filling tube 100 to scrape off the residual material at the bottom of the filling tube 100. After replacing the new bucket, the above components are returned to their positions to continue operation.

[0026] The inner wall and bottom of the filling tube 100 and the bottom of the piston 200 are all coated to reduce the adhesion of the coating. This is existing technology and will not be described in detail.

[0027] In one embodiment, please refer to Figure 1 and Figure 2 The side of the piston 200 is adapted to the port of the feed pipe 110. A support plate 120 for mounting the drive component 400 is fixedly sleeved on the outer side of the top of the filling pipe 100. The sliding baffle 500 is adapted to the bottom of the filling pipe 100 and the piston 200.

[0028] In this embodiment, the piston 200 can block the feed pipe 110 by moving downward, thus stopping the feeding.

[0029] Furthermore, it can be connected to the main body of the filling line via the support plate 120.

[0030] In one embodiment, please refer to Figure 2Limiting sliders 210 are fixedly installed on both sides of the top of the piston 200. Slide grooves 130 adapted to the limiting sliders 210 are opened on both sides of the inner wall of the filling tube 100. Pressure relief holes 140 are opened in the two slide grooves 130.

[0031] In this embodiment, the limiting slider 210 can restrict the rotation of the piston 200, which can work with the lifting component 300 to drive the piston 200 to move up and down. In addition, the pressure relief hole 140 can balance the air pressure inside the filling tube 100 and reduce the movement resistance of the piston 200.

[0032] In one embodiment, please refer to Figure 5 The lifting component 300 includes a threaded sleeve 310 rotatably installed inside the top of the filling tube 100 and a screw 320 threadedly connected to the inner wall of the threaded sleeve 310. The bottom end of the screw 320 is fixedly connected to the top of the piston 200, and the outer side of the threaded sleeve 310 is connected to the driving component 400.

[0033] The drive unit 400 includes a motor 410 fixedly mounted on the top of the support plate 120 and a main bevel gear 420 fixedly mounted on the output shaft of the motor 410. The outer side of the threaded sleeve 310 is fixedly fitted with a driven bevel gear 430 that meshes with the main bevel gear 420.

[0034] In this embodiment, the motor 410 drives the main bevel gear 420 to mesh and drive the slave bevel gear 430 to rotate, which in turn drives the screw sleeve 310 to rotate. The rotation of the screw sleeve 310 can cause the screw 320 and the piston 200 to move up and down under the limit of the limiting slider 210.

[0035] In one embodiment, please refer to Figures 1-5 The top of the screw 320 is fixedly connected to an N-shaped lifting rod 510. Both ends of the bottom of the lifting rod 510 are fixedly provided with sliding sleeves 520 for sliding installation of the sliding baffle 500. A miniature cylinder 530 fixedly connected to the bottom of the sliding baffle 500 is fixedly provided between the two sliding sleeves 520 opposite to the end sides of the feed pipe 110.

[0036] In this embodiment, the lifting and lowering movement of the screw 320 can drive the sliding baffle 500 between the sliding sleeves 520 to move together through the lifting rod 510. That is, when the piston 200 descends to stop the material, the sliding baffle 500 descends with the lifting rod 510 to the bottom side of the filling tube 100. At this time, the sliding baffle 500 can be pushed by the micro cylinder 530 to scrape off the residual paint at the bottom of the filling tube 100.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 5The technical solution of this utility model is described in detail as follows: In use, the filling tube 100 is aligned with the paint bucket to be filled. One end of the feeding tube 110 is connected to the feeding equipment, and the other end is connected to the filling tube 100. The paint is then fed into the filling tube 100 through the feeding tube 110. After a certain amount of paint is injected, the motor 410 is started. The motor 410 drives the main bevel gear 420 to mesh and rotate the driven bevel gear 430, which in turn drives the screw sleeve 310 to rotate. The rotation of the screw sleeve 310 causes the screw 320 and piston 200 to move downwards under the limit of the limiting slider 210. The downward movement of piston 200 will block the feed pipe 110, thereby stopping the feeding. At the same time, piston 200 continues to move downward until it is flush with the bottom of filling pipe 100, so that there is no residual paint in filling pipe 100. Meanwhile, the lifting and lowering movement of screw 320 can drive the sliding baffle 500 between the sliding sleeves 520 to move together through the lifting rod 510. That is, piston 200 descends to stop feeding, and sliding baffle 500 descends with lifting rod 510 to the bottom side of filling pipe 100. At this time, the micro cylinder 530 can push sliding baffle 500 to scrape off the residual paint at the bottom of filling pipe 100, thus achieving the purpose of preventing dripping. After that, a new bucket is replaced, and the above components are returned to their positions to continue operation.

[0038] In summary, this utility model solves the technical problem of paint waste and easy pollution of the working environment caused by residual paint in the feeding pipe by using the lifting component 300 to drive the piston 200 to stop and scrape the material. This achieves the technical effect of saving paint and avoiding pollution of the working environment.
