Description

Technical Field

[0001] The present application relates to the technical field of recycling equipment, and in particular to a powder recycling device for a plastic spraying production line. Background Art

[0002] Powder spraying is a commonly used surface processing technology. During the spraying process, not all raw material powders can adhere to the workpiece. A lot of them will adhere to the assembly line equipment that transports the workpiece, which not only affects the heat dissipation of the equipment, but also reduces the utilization rate of the spraying raw materials. Therefore, they need to be recycled.

[0003] However, the existing powder recovery devices used in the plastic spraying production line mostly suck the powder into the storage container by means of negative pressure. This is feasible for powders with little adhesion, but it is more difficult to recover powders with a little adhesion. If the recovery rate is to be improved, the suction force of the recovery equipment needs to be increased, or the suction head needs to be very close to the adhesion part of the powder, which is not convenient to operate. Summary of the invention

[0004] The purpose of the present application is to provide a powder recovery device for a plastic spraying line which is easy to use and has high recovery efficiency.

[0005] To achieve the above objectives, the present application provides a powder recovery device for a plastic spraying line: comprising a dust box, the outer side of the dust box is fixedly connected to a first fan and a second fan, the output end of the first fan is connected to an air blow cap through an air supply pipe, the input end of the second fan is connected to an air suction hood through a return air pipe, the output end of the first fan and the output end of the second fan are connected to the interior of the dust box, and a material drawer is provided in the dust box, which is suitable for intercepting powder in the airflow passing through the dust box, thereby realizing centralized recovery of plastic spraying powder.

[0006] Preferably, the main body of the dust box is a box body having a configuration cavity therein, the configuration cavity running through a side surface of the box body, the material drawer comprising a filter bag suitable for being embedded in the configuration cavity, the filter bag having air holes that only allow air to pass through, while solid powder will be intercepted.

[0007] Preferably, a sealing plate is fixedly connected to one side of the filter pocket, which is suitable for fitting with the side of the box body connected to the configuration cavity, so as to ensure the air tightness inside the dust collecting box during the powder recovery process and reduce the probability of dust leakage.

[0008] As a preference, a handle is provided on the side of the sealing plate facing away from the filter pocket, and a handle is also provided on the outer side of the box body, so that the dust box is easy to carry and transfer.

[0009] Preferably, the blow cap comprises a pressurized cabin, which has one large end and a small end, the smaller end being provided with an open opening, and the larger end being fixedly connected with a first pipe connecting end suitable for being fixedly connected with the air supply pipe for discharging high-pressure airflow to the outside.

[0010] As a preferred embodiment, the air intake hood includes a collecting cabin, which also has one large end and a small end. The larger end is provided with an open mouth, and the smaller end is fixedly connected to a second pipe connecting end, which is suitable for fixed connection with the return air duct; the open mouth of the blowing cap is also provided with a yield groove, which is suitable for fitting with the outer side surface of the larger end of the collecting cabin, making it easier to form a high-pressure annular airflow.

[0011] Preferably, the blow cap and the suction hood are connected to an operating rod, which includes an extension rod, one end of which is fixedly connected to a bridging plate suitable for connecting the first pipe connection end and the second pipe connection end, and the other end of the extension rod is fixedly connected to a handle to facilitate the operator to adjust the collection position of the spray powder.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] (1) By setting the blowing cap and the suction hood very close to each other, an arc-shaped high-pressure airflow is generated at the end driven by the fan. The powder attached to the assembly line equipment is peeled off under the impact of the high-pressure airflow and then sucked in by negative pressure. The effective suction range is larger, thereby facilitating the recovery operation and improving the recovery efficiency of the powder;

[0015] (2) By providing a material drawer that is easy to disassemble and assemble, powder cleaning can be done quickly, allowing the recovery device to maintain a strong suction force. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0029] like Figure 1-8 The powder recovery device of the spray-painting assembly line shown includes a dust box 6, the interior of which is the main space for storing spray-painted powder. The main part of the dust box 6 is a hollow box body 601. Usually, the box body 601 is a rectangular parallelepiped, and has a configuration cavity 602 inside the box body 601. The configuration cavity 602 only passes through one side of the box body 601. A handle 605 is also provided on the outer side of the box body 601. The side where the handle 605 is located is not the same side as the side through which the configuration cavity 602 passes.

[0030] The outer side of the dust box 6 is fixedly connected with a first fan 603 and a second fan 604, both of which can push air to generate airflow. The output end of the first fan 603 and the output end of the second fan 604 are connected to the inside of the dust box 6, that is to say, the direction of the airflow pushed by the two is the same. The two fans actually share the work of one fan, effectively reducing the power of a single fan, which is beneficial to avoid overheating during long-term operation. The input end of the second fan 604 is connected to an air suction hood 2 through a return air duct 4, which is used to gather the airflow to the end of the return air duct 4. The air suction hood 2 includes a collecting cabin 201, which also has one large end and a small end. The larger end is provided with an open mouth, and the smaller end is fixedly connected with a second pipe connecting end 202 for fixed connection with the return air duct 4. The structure of the collecting cabin 201 with an enlarged end is similar to a horn, which facilitates the air to be inhaled.

[0031] The output end of the first fan 603 is connected to a blowing cap 1 through an air supply pipe 3, which is used to discharge high-pressure airflow outward. The blowing cap 1 includes a pressurized cabin 101, which has a large end and a small end. The smaller end is provided with an open mouth, and the larger end is fixedly connected with a first pipe connecting end 103, which is suitable for being fixedly connected to the air supply pipe 3. The end-contracted structure of the blowing cap 1 is conducive to squeezing the airflow so that the airflow has a higher air pressure, thereby making it easier to blow up the powder attached to the assembly line components. The open mouth of the blowing cap 1 is also provided with a clearance groove 102, which is actually located at the end of the pressurized cabin 101, and is used to fit with the outer side surface of the larger end of the collecting cabin 201, so that the end of the collecting cabin 201 is closer to the end of the pressurized cabin 101, and the high-pressure airflow blown out from the pressurized cabin 101 can immediately enter the collecting cabin 201 after blowing up the powder, that is, a circular arc-shaped airflow is formed, which can effectively avoid dust pollution of the environment.

[0032] In order to maintain the stability of the relative position of the blowing cap 1 and the suction hood 2 during operation, the blowing cap 1 and the suction hood 2 are also connected to an operating rod 5, which includes an extension rod 503. The extension rod 503 is relatively long and almost occupies most of the operating rod 5. One end of the extension rod 503 is fixedly connected to a bridging plate 501 for connecting the first pipe connection end 103 and the second pipe connection end 202. Specifically: the bridging plate 501 has a pair of connecting sleeves 502, which are respectively located at the two ends of the bridging plate 501. The outer side surface of the first pipe connection end 103 is provided with a first limiting groove 104, which is exactly matched with one connecting sleeve 502, and the outer side surface of the second pipe connection end 202 is provided with a second limiting groove 203, which is exactly matched with the other connecting sleeve 502. The connecting sleeve 502 can adopt a clamp structure to facilitate installation and disassembly operations. The other end of the extension rod 503 is fixedly connected to a handle 504, which is convenient for the staff to hold the operating rod 5.

[0033] A material drawer 7 is provided in the dust box 6. The powder entering the dust box 6 will eventually remain in the material drawer 7. The specific structure of the material drawer 7 includes a filter pocket 701. The filter pocket 701 usually has five side walls, which are all hard filter plates. That is to say, the filter pocket 701 is a rectangular parallelepiped with one end open. The filter pocket 701 is embedded in the configuration cavity 602, and the only open end of the filter pocket 701 faces the direction of the airflow. The side wall of the filter pocket 701 has air holes 702, which only allow air to pass through, so as to intercept the powder in the airflow passing through the dust box 6. A sealing plate 703 is fixedly connected to one side of the filter pocket 701, which is used to fit the side of the configuration cavity 602 connected to the box body 601 to ensure the sealing of the inside of the configuration cavity 602 when the material drawer 7 and the dust box 6 are in the matching state. A handle 704 is provided on the side of the sealing plate 703 facing away from the filter pocket 701, so as to facilitate the separation of the material drawer 7 from the dust box 6.

[0034] Working principle: When in use, the staff holds the handle 605 with one hand to lift the dust box 6, and holds the grip 504 with the other hand to lift the operating rod 5, starts the first fan 603 and the second fan 604, and lets the blowing cap 1 and the suction hood 2 face the place where the spray powder is attached on the assembly line equipment. The high-pressure airflow ejected by the blowing cap 1 blows up the attached powder, and then it is sucked into the suction hood 2 with a strong negative pressure inside. When the airflow carrying the spray powder passes through the dust box 6, the powder in the air will be intercepted by the filter bag 701, and the air will continue to circulate through the air vents 702 of the filter bag 701. When the clean powder is obviously not sucked, it means that the powder in the material drawer 7 has been collected too much, and the filter bag 701 can be pulled out and emptied and then inserted into the box body 601 to restore the suction force. This can be repeated to complete the powder recovery work on the entire assembly line.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
