Description

Technical Field

[0001] This utility model belongs to the field of antistatic woven bag production and processing technology, specifically, it relates to an antistatic woven bag raw material pretreatment device. Background Technology

[0002] Antistatic woven bag raw material pretreatment equipment is a device specifically designed to pretreat raw materials before woven bag production. Its core function is to improve the antistatic properties of raw materials through a series of process steps, ensuring the quality and safety of subsequent woven bags. This device typically integrates functional modules such as dust removal, preheating, antistatic agent spraying, and drying to achieve an automated and large-scale pretreatment process.

[0003] The prior art discloses an antistatic device for processing plastic woven bags (CN215551369U), which includes a base, symmetrically arranged fixing plates fixedly connected to the top two sides of the base, a top plate fixedly connected to the opposite side of the top of the two fixing plates, a high-voltage power generator fixedly connected to the top outer wall of the top plate, a mounting frame fixedly connected to the bottom outer wall of the top plate, and a connecting plate fixedly connected to the bottom end of the mounting frame, and ion needles evenly distributed on both sides of the bottom of the connecting plate, and the high-voltage power generator is connected to the ion needles through wires.

[0004] Search results revealed that the patent uses an ion needle discharge structure, which can only eliminate static electricity on the surface of the woven bag. It cannot solve the problem of unneutralized charges generated by friction inside the raw material. Furthermore, the existing technology lacks dust pretreatment measures for the woven bag raw material, which causes dust to adhere to the surface of the raw material and affect the effect of subsequent antistatic woven bag production and processing.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An antistatic woven bag raw material pretreatment device, comprising:

[0008] A dust collector box has a door hinged to one side. Inside the dust collector box, a dust collector component and a support component are movably arranged. The dust collector box is movably supported by the support component. The dust collector component includes an inner nozzle, two air jet pipes, and two outer nozzles symmetrically arranged vertically. The two air jet pipes are symmetrically arranged on both sides of the inner nozzle, and the two air jet pipes are perpendicularly intersecting the two outer nozzles.

[0009] In a preferred embodiment of this utility model, the dust collection box is symmetrically provided with a diversion structure, the diversion structure including a diversion plate and an electric fan, the diversion plate being fixedly installed on the inner wall of the dust collection box, and the electric fan being installed on the inner top surface of the dust collection box.

[0010] In a preferred embodiment of this utility model, an ultraviolet curing lamp is symmetrically arranged on the inner side of the diversion plate, a one-way valve is provided at the bottom of the dust collection box, and a dust extraction pipe is installed on the bottom surface of the dust collection box. The dust extraction pipe and the one-way valve are both located between the two diversion plates.

[0011] In a preferred embodiment of this utility model, the support includes a support base and a positive and negative lead screw. The support base is fixedly installed on the inner wall of the dust collector. A motor is fixedly installed on one side of the outer wall of the dust collector. The positive and negative lead screw is rotatably connected to one end of the support base near the dust collector. The output end of the motor passes through the dust collector and is connected to one end of the positive and negative lead screw.

[0012] In a preferred embodiment of this utility model, each end of the positive and negative lead screw is threaded with a movable block, which moves between the dust collection box and the positive and negative lead screw, and the side of the movable block away from the dust collection box is fixedly connected to the air jet pipe.

[0013] In a preferred embodiment of this utility model, a high-pressure gas input pipe is installed on the dust collection box. The input end of the high-pressure gas input pipe is connected to an air pump, and a corrugated pipe is fixedly connected to each of the two output ends of the high-pressure gas input pipe. The two corrugated pipes are connected to different jet pipes.

[0014] In a preferred embodiment of this utility model, the dust removal box is provided with a coating input pipe for connecting an external coating storage device. The coating input pipe is snapped into the other end of the support base. The internal spray nozzle passes through the support base and communicates with the coating input pipe. The two external spray nozzles are arranged symmetrically above and below the internal spray nozzle.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. For woven bags to be pretreated with antistatic agent before antistatic treatment, the antistatic agent is sprayed directly into the gaps inside the raw material by spraying atomized airflow into the inside of the woven bag through an internal nozzle. Two external nozzles spray atomized airflow to cover the outer surface of the raw material. Combined with vertically intersecting air jet pipes to assist in purging, and combined with ultraviolet curing lamps to accelerate the curing of the antistatic agent, a uniform conductive film layer is formed, which realizes the deep neutralization of the charge on the inner and outer surfaces and inside the raw material, solving the problem that traditional devices can only deal with surface static electricity.

[0017] 2. For woven bags before antistatic treatment, a preliminary dust removal pretreatment is performed. The motor drives the positive and negative lead screws to rotate, causing the moving blocks at both ends to move relative to each other along the positive and negative lead screws, thereby adjusting the distance between the two air jet pipes to adapt to woven bag materials of different sizes. The high-pressure airflow from the air jet pipes can blow out the dust attached to the inside of the material. The electric fan guides the dust-laden airflow to slide down from the diversion plate area. At the same time, the one-way valve and dust extraction pipe connect the dust to the external dust collection device for centralized treatment, avoiding secondary dust pollution.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] An antistatic woven bag raw material pretreatment device, such as Figure 1 , Figure 3 and Figure 5 As shown, including

[0028] The dust collector 10 has a hinged door 11 on one side. Inside the dust collector 10, dust collector components and supporting components are movably arranged. The dust collector components are movably supported by the supporting components. The dust collector components include an inner nozzle 23, two air jet pipes 27, and two symmetrically arranged outer nozzles 22. The two air jet pipes 27 are symmetrically arranged on both sides of the inner nozzle 23, and the two air jet pipes 27 and the two outer nozzles 22 are arranged perpendicularly. The inner wall of the dust collector 10 is coated with a Teflon coating to reduce electrostatic adsorption. The door 11 adopts a double-sealed structure. When in use, closing the door and the dust collector 10 can prevent leakage of internal dust or antistatic agent. The dust collector components are movably supported by the supporting components, which are driven by a motor 20 with positive and negative lead screws 25. This allows for the support of different specifications of woven bag materials, creating internal space for spraying antistatic agent and dust discharge.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a flow diversion structure is symmetrically arranged inside the dust collection box 10. The flow diversion structure includes a flow diversion plate 17 and an electric fan 19. The flow diversion plate 17 is fixedly arranged on the inner wall of the dust collection box 10, and the electric fan 19 is installed on the inner top surface of the dust collection box 10. The flow diversion plate 17 is an arc-shaped plate, and an installation groove is opened on the inner top surface of the dust collection box 10. The electric fan 19 is installed in the installation groove.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an ultraviolet curing lamp 18 is symmetrically arranged on the inner side of the diversion plate 17. A one-way valve 16 is provided at the bottom of the dust collection box 10. A dust extraction pipe 15 is installed on the bottom surface of the dust collection box 10. The dust extraction pipe 15 and the one-way valve 16 are both located between the two diversion plates 17. The dust extraction pipe 15 corresponding to the one-way valve 16 faces the same direction. The dust extraction pipe 15 is connected to a dust removal device.

[0031] The working principle is as follows: the arc-shaped diversion plate 17, together with the top electric fan 19, can assist the atomized antistatic agent sprayed from the dust removal component to sink and the dust sprayed from the jet pipe 27 to fall. The dust extraction pipe 15 is connected to the negative pressure fan, and the dust is collected in a directional manner through the one-way valve 16. The ultraviolet curing lamp 18 uses an LED light source, and the curing time is automatically adjusted by the external PLC controller to ensure that the antistatic agent coating is completely cured in a short time.

[0032] like Figure 4 and Figure 5As shown, the support includes a support base 24 and a positive and negative lead screw 25. The support base 24 is fixedly installed on the inner wall of the dust collector 10. A motor 20 is fixedly installed on one side of the outer wall of the dust collector 10. The positive and negative lead screw 25 is rotatably connected to one end of the support base 24 near the dust collector 10. The output end of the motor 20 passes through the dust collector 10 and is connected to one end of the positive and negative lead screw 25. The support base 24 is composed of a square seat and an annular seat. The positive and negative lead screw 25 is rotatably installed in the square seat through a bearing.

[0033] like Figure 5 As shown, each end of the positive and negative lead screw 25 is threaded with a movable block 28. The movable block 28 moves between the dust collection box 10 and the positive and negative lead screw 25. The side of the movable block 28 away from the dust collection box 10 is fixedly connected to the jet pipe 27.

[0034] like Figure 5 As shown, a high-pressure gas input pipe 13 is installed on the dust collection box 10. The input end of the high-pressure gas input pipe 13 is connected to an air pump 14. The output ends of the high-pressure gas input pipe 13 are respectively fixedly connected to a bellows 26. The two bellows 26 are connected to different jet pipes 27. The high-pressure gas input pipe 13 consists of a U-shaped pipe and a J-shaped pipe. The J-shaped pipe is connected to the air pump 14. The two ends of the U-shaped pipe are respectively connected to a J-shaped bellows 26.

[0035] The working principle is as follows: the surface of the jet pipe 27 is evenly distributed with jet micro-holes. When the motor 20 starts, the motor 20 drives the positive and negative lead screws 25 to rotate, so that the moving blocks 28 at both ends of the positive and negative lead screws 25 move synchronously in opposite directions, driving the corresponding jet pipes 27 to move axially. At the same time, the high-pressure airflow passes through the air pump 14 and flows through the high-pressure gas input pipe 13, and then enters the two jet pipes 27 through the two ends of the U-shaped tube of the high-pressure gas input pipe 13 respectively, thereby removing the dust inside the woven bag raw material. The relative movement of the two jet pipes 27 is used to adapt to the setting of woven bag raw materials of different specifications. At the same time, when the two jet pipes 27 move, the corresponding corrugated pipes 26 automatically extend and retract to ensure a continuous and stable supply of high-pressure airflow.

[0036] like Figure 1 and Figure 3 As shown, the dust collection box 10 is equipped with a coating input pipe 12 for connecting an external coating storage device. The coating input pipe 12 is snapped into the other end of the support base 24. The internal nozzle 23 passes through the support base 24 and communicates with the coating input pipe 12. Two external nozzles 22 are arranged symmetrically above and below the internal nozzle 23. The coating input pipe 12 is snapped into the annular seat of the support base 24. A circular hole is opened on the side of the annular seat away from the square seat, and the internal nozzle 23 passes through the circular hole.

[0037] The specific implementation method is as follows: the internal spray nozzle 23 adopts a high-pressure atomizing nozzle, which can produce antistatic agent droplets. The coating input pipe 12 is connected to the coating storage device through a metering pump. The spraying flow rate is precisely controlled by the metering pump. The external spray nozzle 22 has wide-angle atomizing nozzles arranged symmetrically at the top and bottom, which are set at an angle with the internal spray nozzle 23 to form an upper, middle and lower three-dimensional spraying area. In use, the motor 20 is started to drive the positive and negative lead screws 25 to rotate. The moving blocks 28 at both ends of the positive and negative lead screws 25 move relative to each other, driving the jet pipes 27 to adjust their horizontal position until the distance between the two jet pipes 27 is adapted to the width of the woven bag material. The woven bag material is then placed on the two jet pipes 27. The box door 11 is closed to seal the dust collection box 10. The air pump 14 is started. High-pressure gas enters through the high-pressure gas input pipe 13 and is diverted to the two J-shaped corrugated pipes 26. Then, it enters the jet pipes 27 through the corrugated pipes 26. The jet pipes 27 spray into the woven bag material. High-pressure airflow is sprayed from the jet nozzle 27. While blowing out the internal charge of the raw material, the high-pressure airflow also blows the dust attached to the inside of the raw material off the surface. The dust-laden airflow flows downward along the arc-shaped guide plate 17. The electric fan 19 blows and accelerates the airflow to the bottom of the dust collection box 10. The dust is carried by the airflow to the one-way valve 16 and collected by the dust collection device connected to the dust extraction pipe 15. After the dust treatment is completed, the coating storage device and metering pump are started. The inner nozzle 23 sprays atomized antistatic agent synchronously to neutralize the charge generated by friction inside the raw material. The upper and lower outer nozzles 22 spray the same atomized antistatic agent to the upper and lower sides of the raw material to neutralize the external surface charge, thus achieving the neutralization of the internal and external charges of the woven bag raw material. After the spraying is completed, the ultraviolet curing lamp 18 is started to irradiate and accelerate the curing of the antistatic agent into a film. After the treatment is completed, the box door 11 is opened and the woven bag raw material is removed, completing the pretreatment process of the woven bag raw material body in one go.
