Description

Technical Field

[0001] This utility model relates to the field of leather production technology, specifically to a uniform spraying device for leather finishing agents. Background Technology

[0002] Modern leather production has evolved from the traditional three-step process of preparation, tanning, and finishing to a two-stage process of dry and wet processing. Wet processing has begun to be separated from traditional tanneries, with factories set up near the raw hide production sites or slaughterhouses to tan raw hides into wet blue leather or wet white leather. Traditional tanneries only perform dry processing, turning wet blue or wet white leather into finished leather. This saves on salt used for preservatives in raw hides, reduces pollution, and improves the quality of finished leather. Modern leather shoe manufacturing is based on the standardization of components and assembly of production, implementing small-batch, multi-variety production to adapt to changes in market demand.

[0003] Publication No. CN211079200U discloses a spraying device for leather production. By incorporating an outer protective box, operators can place the leather to be sprayed on top of a leather support plate. A switch panel controls a linear motor to lower the entire outer protective box. When the automatic spray gun inside the outer protective box reaches the appropriate position and the outer protective box completely surrounds the leather support plate, the switch panel is used to activate the automatic spray gun to spray the leather at the bottom. This method ensures that the spraying material is blocked by the inner wall of the outer protective box, preventing splashing and thus avoiding negative impacts on the production environment and operators. However, this patent still has the following problems in practical use:

[0004] By incorporating an outer protective box, operators can place the leather to be sprayed on top of the leather support plate and control the linear motor via the switch panel to lower the entire outer protective box. Once the automatic spray gun inside the outer protective box has descended to the appropriate position and the outer protective box completely surrounds the leather support plate, the automatic spray gun can be activated using the switch panel to spray the leather at the bottom. In this way, the spray material is directly blocked by the inner wall of the outer protective box during the entire spraying process, preventing it from splashing out and thus avoiding the negative impact of splashed spray material on the production environment and operators. However, because the bottom of the outer protective box is hollow, the nozzle cannot filter dust from the air when not in use. This allows dust in the air to enter the nozzle, causing it to become clogged and reducing its service life to some extent.

[0005] A uniform spraying device for leather finishing agents is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a uniform spraying device for leather finishing agents, to solve the problems mentioned in the background art. Currently, the device uses an outer protective box. During use, the operator can place the leather to be sprayed on top of the leather support plate and control the linear motor via a switch panel to lower the entire outer protective box. When the automatic spray gun inside the outer protective box reaches the appropriate position and the outer protective box completely surrounds the leather support plate, the automatic spray gun can be activated using the switch panel to spray the leather at the bottom. In this way, the spraying material is directly blocked by the inner wall of the outer protective box and will not splash out, thus avoiding the negative impact of splashed spraying material on the production environment and operators. However, because the bottom of the outer protective box is hollow, the nozzle cannot filter dust from the air when not in use. This allows dust in the air to enter the nozzle, causing blockage and reducing the lifespan of the nozzle.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a uniform spraying device for leather finishing agent, including a support base, wherein a connecting frame is fixedly installed on the top surface of the support base;

[0008] A cylinder is fixedly installed in the middle of the top surface of the connecting frame, and a slide plate is fixedly connected to the bottom surface of the cylinder. Several slide rods are connected through the two sides of the slide plate. The top surface of the slide rod is fixedly connected to the connecting frame, and the bottom surface of the slide rod is fixedly connected to the support base. A groove is opened in the middle of the bottom surface of the slide plate, and a protective cover is slidably connected inside the groove.

[0009] Also includes:

[0010] The protective cover has fixing components on both sides.

[0011] The fixing component includes a connecting sleeve that is fixedly connected to the protective cover;

[0012] A pull rod is connected through the inside of the connecting sleeve.

[0013] Preferably, a return spring is sleeved on the surface of the pull rod, a sliding plate is fixedly connected to one side of the return spring, and the other side of the return spring is fixedly connected to the connecting sleeve.

[0014] Preferably, the connecting sleeve has symmetrically installed blocks inside, and the blocks are in contact with the sliding plate.

[0015] Preferably, a connecting pipe is connected through one side of the top surface of the connecting frame, a conveying pipe is connected through the bottom surface of the connecting pipe, a nozzle is connected through the bottom surface of the conveying pipe, the connecting pipe is connected through the slide plate, and a fixing frame is connected through both sides of the surface of the conveying pipe, with the top surface of the fixing frame fixedly connected to the groove.

[0016] Preferably, electric push rods are fixedly installed on both sides of the top surface of the skateboard, and the output end of the electric push rod passes through one side surface of the skateboard and is fixedly connected to the protective cover.

[0017] Preferably, a filter screen is snapped onto the bottom surface of the protective cover, a number of locking blocks are fixedly installed around the top surface of the filter screen, and a number of locking slots are opened around the bottom surface of the protective cover, with the locking blocks engaging with the locking slots.

[0018] Preferably, the pull rod is connected through the protective cover and the locking block.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This uniform spraying equipment for leather finishing agents, by setting up a fixing component and a filter screen, allows the filter screen to filter dust in the air when the spray nozzle is not in use, thereby reducing dust from entering the spray nozzle and causing clogging. The fixing component makes it convenient to disassemble and install the filter screen. The specific details are as follows:

[0020] 1. By setting up a fixing component and a filter screen, when the leather needs to be sprayed, the operator can use considerable force to pull the lever, causing it to separate from the locking block and protective cover. Then, by pulling the filter screen, the locking block on the filter screen separates from the slot on the protective cover, thus completing the removal of the filter screen. At the same time, when the lever is pulled, it will drive the sliding plate to move. The movement of the sliding plate will compress the return spring, causing it to deform. After the leather is sprayed, by engaging the locking block on the filter screen with the slot on the protective cover, the lever can be loosened, causing the return spring to compress the sliding plate, thus returning the sliding plate to its original position. The sliding plate and the lever are fixedly connected, which means that when the sliding plate returns to its original position, it can drive the lever to return to its original position, allowing the lever to pass through the protective cover and locking block again, thus providing an auxiliary fixing effect for the filter screen and ensuring that the filter screen does not fall off.

[0021] 2. By setting up a cylinder, slide plate, slide bar, and protective cover, and after removing the filter screen, the cylinder is activated via the control terminal, causing the cylinder output to drive the slide plate to slide on the slide bar. The descent of the slide plate causes the protective cover to descend as well. Once the protective cover descends and its bottom is tightly fitted against the top of the leather bracket, the paint is conveyed through a conveying device into the connecting pipe, then through the connecting pipe into the conveying pipe, and finally sprayed out through the nozzle on the conveying pipe. This allows the leather on the leather bracket to be sprayed. The protective cover prevents the sprayed material from splashing outwards during the entire spraying process, thus avoiding the negative impact of splashed sprayed material on the production environment and operators.

[0022] 3. By setting up an electric push rod and a protective cover, when the nozzle needs to be inspected, the electric push rod is activated through the control terminal, causing the output end of the electric push rod to drive the protective cover to rise, thereby exposing the nozzle inside the protective cover, which facilitates the inspection and maintenance of the nozzle. At the same time, the nozzle and the delivery pipe are connected by threads, which makes it relatively convenient to replace the nozzle. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a uniform spraying device for leather finishing agent, including a support base 1, a connecting frame 2 fixedly installed on the top surface of the support base 1; a cylinder 3 fixedly installed in the middle of the top surface of the connecting frame 2, a slide plate 4 fixedly connected to the bottom surface of the cylinder 3, a plurality of slide rods 5 penetratingly connected to both sides of the slide plate 4, the top surface of the slide rods 5 fixedly connected to the connecting frame 2, the bottom surface of the slide rods 5 fixedly connected to the support base 1, a groove 10 is formed in the middle of the bottom surface of the slide plate 4, and a protective cover 12 is slidably connected inside the groove 10; it also includes: fixing components 14 provided on both sides of the protective cover 12; wherein, the fixing components 14 include connecting sleeves 1401 fixedly connected to the protective cover 12; wherein, a pull rod 1402 is penetratingly connected inside the connecting sleeves 1401, such as Figure 1-5 As shown, by setting the fixing component 14 and the filter screen 13, the function of the filter screen 13 is to filter the dust in the air when the nozzle 8 is not in use, thereby reducing the dust from entering the nozzle 8 and causing the nozzle 8 to become clogged. The fixing component 14 makes it easier to disassemble and install the filter screen 13. At the same time, the cylinder 3 is electrically connected to the control terminal.

[0031] A return spring 1403 is sleeved on the surface of the pull rod 1402. A sliding plate 1404 is fixedly connected to one side of the return spring 1403, and the other side of the return spring 1403 is fixedly connected to the connecting sleeve 1401. Stops 1405 are symmetrically installed inside the connecting sleeve 1401, and the stops 1405 are in close contact with the sliding plate 1404. Figure 5As shown, when the leather needs to be sprayed, the operator can use considerable force to pull the lever 1402, causing it to separate from the locking block 15 and the protective cover 12. Then, by pulling the filter screen 13, the locking block 15 on the filter screen 13 separates from the locking groove 16 on the protective cover 12, thus completing the disassembly of the filter screen 13 and preventing it from obstructing the view. Meanwhile, the return spring 1403 can be made of alloy spring steel to ensure its stability. Under prolonged and frequent deformation, 1403 can slow down the fatigue time, thus ensuring the service life of the return spring 1403 to a certain extent. At the same time, anti-corrosion and anti-rust coatings can be applied according to the actual situation to prevent the return spring 1403 from rusting. In addition, the return spring 1403 made of alloy spring steel has greater stiffness and elasticity, which allows the pull rod 1402 to pass through the protective cover 12 and the locking block 15 steadily, so that the pull rod 1402 will not separate from the protective cover 12 and the locking block 15 without interference from external forces.

[0032] A connecting pipe 6 is connected through one side of the top surface of the connecting frame 2. A conveying pipe 7 is connected through the bottom surface of the connecting pipe 6. A nozzle 8 is connected through the bottom surface of the conveying pipe 7. The connecting pipe 6 is connected through the slide plate 4. Fixing frames 9 are connected through both sides of the surface of the conveying pipe 7. The top surface of the fixing frame 9 is fixedly connected to the groove 10. Figure 2 As shown, the connecting pipe 6 is fixedly installed with the conveying device in the prior art. The conveying device includes a paint tank, a discharge pipe, a water pump, and a feed pipe, so that the paint can be conveyed into the interior of the connecting pipe 6, and then conveyed into the interior of the conveying pipe 7 through the connecting pipe 6, and finally sprayed out through the nozzle 8. At the same time, the nozzle 8 can be selected as an atomizing nozzle, so that the paint is evenly sprayed on the leather, thereby achieving uniform spraying of the leather. The connecting pipe 6 is a flexible hose.

[0033] Electric push rods 11 are fixedly installed on both sides of the top surface of the slide plate 4. The output end of the electric push rod 11 passes through one side surface of the slide plate 4 and is fixedly connected to the protective cover 12. Figure 2 As shown, by setting up an electric push rod 11 and a protective cover 12, when the nozzle 8 needs to be inspected, the electric push rod 11 is activated through the control terminal, causing the output end of the electric push rod 11 to drive the protective cover 12 to rise, thereby exposing the nozzle 8 inside the protective cover 12, which facilitates the inspection and maintenance of the nozzle 8. Simultaneously, the nozzle 8 is threadedly connected to the delivery pipe 7, making it relatively convenient to replace the nozzle 8. The electric push rod 11 is model LAM33-A, and the electric push rod 11 is electrically connected to the control terminal.

[0034] A filter screen 13 is snapped onto the bottom surface of the protective cover 12. Several locking blocks 15 are fixedly installed around the top surface of the filter screen 13. Several slots 16 are formed around the bottom surface of the protective cover 12, and the locking blocks 15 engage with the slots 16. The pull rod 1402 is connected through the protective cover 12 and the locking blocks 15. Figure 2-4 As shown, after the locking block 15 on the filter screen 13 is engaged with the locking groove 16 on the protective cover 12, the pull rod 1402 is loosened, causing the return spring 1403 to press the sliding plate 1404, thereby causing the sliding plate 1404 to return to its original position. At the same time, the sliding plate 1404 and the pull rod 1402 are fixedly connected through each other, which means that when the sliding plate 1404 returns to its original position, it can drive the pull rod 1402 to return to its original position, so that the pull rod 1402 passes through the protective cover 12 and the locking block 15 again, thereby playing an auxiliary role in fixing the filter screen 13 and ensuring that the filter screen 13 will not fall off.

[0035] Working principle: Before using this leather finishing agent uniform spraying equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, by first setting the fixing component 14 and the filter screen 13, when the leather needs to be sprayed, the operator can use a large force to pull the lever 1402, causing the lever 1402 to be pulled. After the lever 1402 is pulled, it separates from the locking block 15 and the protective cover 12. Then, by pulling the filter screen 13, the locking block 15 on the filter screen 13 separates from the locking groove 16 on the protective cover 12, thus completing the disassembly of the filter screen 13. At the same time, when the lever 1402 is pulled, it will drive the sliding plate 1404 to move. The movement of the sliding plate 1404 will compress the return spring 1403, thereby causing the return spring 1403 to... 3. After the leather is coated, the filter screen 13 is engaged with the slot 16 on the protective cover 12 by locking the clip 15 on the filter screen 13. Then, by loosening the pull rod 1402, the return spring 1403 will press the sliding plate 1404, thereby restoring the sliding plate 1404 to its original position. At the same time, the sliding plate 1404 and the pull rod 1402 are fixedly connected through the filter screen. This means that when the sliding plate 1404 returns to its original position, it can drive the pull rod 1402 to return to its original position. This allows the pull rod 1402 to pass through the protective cover 12 and the clip 15 again, thus providing an auxiliary fixing effect for the filter screen 13 and ensuring that the filter screen 13 will not fall off.

[0036] Secondly, by setting up cylinder 3, slide plate 4, slide bar 5, and protective cover 12, and after removing filter screen 13, cylinder 3 is started through the control terminal, so that the output end of cylinder 3 drives slide plate 4 to slide on slide bar 5. The descent of slide plate 4 can drive the protective cover 12 to descend. After the protective cover 12 descends and the bottom is tightly attached to the top of the leather bracket, the paint is transported to the inside of connecting pipe 6 through the conveying device, and then to the inside of conveying pipe 7 through connecting pipe 6. Finally, it is sprayed out through the nozzle 8 on conveying pipe 7, so that the leather on the leather bracket can be sprayed. The function of protective cover 12 is to prevent the sprayed material from being directly blocked by the outer protective box on the inner wall during the entire spraying process, thus avoiding the negative impact of the sprayed material on the production environment and operators.

[0037] Finally, by setting up an electric push rod 11 and a protective cover 12, when it is necessary to inspect the nozzle 8, the electric push rod 11 is activated through the control terminal, so that the output end of the electric push rod 11 drives the protective cover 12 to rise, thereby exposing the nozzle 8 inside the protective cover 12, which facilitates the inspection and maintenance of the nozzle 8. At the same time, the nozzle 8 and the delivery pipe 7 are connected by threads, which makes it relatively convenient to replace the nozzle 8.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
