Description

Technical Field

[0001] This invention relates to the field of plastic woven bag production technology, specifically to a dust removal device for plastic woven bag production. Background Technology

[0002] Plastic woven bags are bags woven from plastic fibers, usually made of materials such as polypropylene. Due to their durability, lightness, and waterproofness, plastic woven bags are widely used in agriculture, construction, transportation and other fields. During the production process of plastic woven bags, a large amount of plastic dust and particles are generated. If not handled in time, it may affect product quality, employee health and the production environment. When cutting plastic woven bags, some plastic dust and particles are generated. Traditional dust removal devices are mostly installed above the cutting station, using suction to create negative pressure to draw the plastic dust and particles into the channel, reducing the impact of plastic dust and particles on the working environment. However, during dust removal, because some plastic dust and particles are large or plentiful, they can easily clog the channel, requiring frequent manual cleaning and maintenance, and in severe cases, machine shutdown, which affects the overall processing efficiency of plastic woven bags. To address these issues, we propose a dust removal device for plastic woven bag production. Summary of the Invention

Detailed Implementation

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

[0030] Example: Figure 1-9 As shown, the present invention provides a dust removal device for the production of plastic woven bags, including a mounting top frame 1, and a primary dust removal mechanism 2 is fixedly installed at the bottom end of the mounting top frame 1. The entire dust removal device is fixedly installed at a suitable position in the cutting station of plastic woven bag production through the mounting top frame 1. The primary removal mechanism 2 includes a primary removal outer cylinder 21, which is fixedly installed at the bottom of the mounting frame 1. A primary removal middle cylinder 22 is rotatably mounted in the primary removal outer cylinder 21, and a primary removal inner cylinder 23 is rotatably mounted in the primary removal middle cylinder 22. The primary removal middle cylinder 22 is easy to rotate in the primary removal outer cylinder 21 and is easy to rotate outside the primary removal inner cylinder 23. Two dust removal channels 211 are symmetrically distributed on the primary removal outer cylinder 21. The two dust removal channels 211 are arranged horizontally. Waste removal channels 212 are provided at the top and bottom of the primary removal outer cylinder 21. The two dust removal channels 211 and the two waste removal channels 212 are vertically distributed. Multiple sets of dust storage channels 221 are arranged in a ring array on the primary removal middle cylinder 22. In the initial state, the two dust removal channels 211 and the corresponding set of dust storage channels 221 are interconnected; the two waste removal channels 212 and the corresponding set of dust storage channels 221 are interconnected. Multiple dust collection channels 221 are fixedly installed with ventilation filter plates 222 by screws at opposite ends, which facilitates the disassembly of ventilation filter plates 222 and forms a dust collection chamber at the opposite ends of each dust collection channel 221. The ventilation filter plates 222 facilitate ventilation and perform primary filtration of the inhaled plastic dust and particles. The filtered material is retained in the corresponding dust collection chamber. The outer side of the primary cleaning inner cylinder 23 is provided with a dust removal groove 231 corresponding to the dust removal channel 211. The two dust removal grooves 231 are arranged horizontally. The top and bottom of the primary cleaning inner cylinder 23 are provided with waste removal grooves 232 corresponding to the waste removal channel 212. One end of the primary cleaning inner cylinder 23 is provided with a suction channel 2311 that communicates with the dust removal groove 231. A first channel 2312 is provided between the two suction channels 2311. The two suction channels 2311 are connected by the first channel 2312. A connecting suction pipe 2313 is fixedly attached to the ends of the two suction channels 2311. The two suction channels 2311 are connected by the connecting suction pipe 2313. A secondary cleaning mechanism 3 is provided at the end of the connecting suction pipe 2313 away from the primary cleaning inner cylinder 23. A dust collection frame 5 is fixedly installed on the outer wall of the primary dust collection outer cylinder 21 at the dust collection channel 211. The dust collection frame 5 and the dust collection channel 211 are interconnected. During specific installation and use, the length and structural type of the dust collection frame 5 are selected according to the different cutting stations of plastic woven bags. After the entire device is installed, the dust collection ports at the bottom of the two dust collection frames 5 correspond to the cutting parts of the woven bags, which facilitates the precise suction of plastic dust and particles generated at the cutting parts of the woven bags. The end of the primary dust collection inner cylinder 23 near the secondary dust collection mechanism 3 extends out to the end of the primary dust collection middle cylinder 22 and is fixedly installed with a U-shaped frame 25. The U-shaped frame 25 is fixedly installed on the dust collection outer frame 5. By setting the U-shaped frame 25 and fixing it on the dust collection outer frame 5, the primary dust collection inner cylinder 23 is fixed, which facilitates the rotation of the primary dust collection middle cylinder 22 on the outside of the primary dust collection inner cylinder 23. A waste removal frame 6 is fixedly installed on the outer wall of the outer cylinder 21 at the location of the waste removal channel 212. A waste removal pipe head 61 is fixedly installed at the end of the waste removal frame 6. A waste removal main pipe 62 is fixedly installed at the end of the waste removal pipe head 61 away from the waste removal frame 6. The waste removal main pipe 62 is used to connect the two waste removal frames 6. An installation pipe 63 is vertically installed at the bottom of the waste removal main pipe 62. A processing mechanism 4 is provided at the end of the installation pipe 63 away from the waste removal main pipe 62.

[0031] The secondary removal mechanism 3 includes a secondary outer frame 31. A third tube 311 is fixedly installed at one end of the secondary outer frame 31, and a third valve 32 is fixedly installed at the end of the third tube 311. The end of the third valve 32 is fixedly installed at the end of the connecting suction pipe 2313 away from the primary removal inner cylinder 23, connecting the secondary removal mechanism 3 and the primary removal mechanism 2. A filter inner core 33 is detachably installed in the secondary outer frame 31 for easy removal and replacement. A fourth tube 312 is fixedly installed at the end of the secondary outer frame 31 away from the third tube 311, and a vacuum suction hose 34 is fixedly installed at the end of the fourth tube 312 away from the secondary outer frame 31. In use, the end of the vacuum suction hose 34 is connected to the suction end of the vacuum system. The system controls the activation of the vacuum system and the third valve 32, creating a negative pressure at the bottom of the two vacuum frames 5. This precisely sucks up the plastic dust and particles generated at the cut part of the woven bag. The dust and particles are drawn into the corresponding set of dust storage slots 221 through the vacuum frames 5 on both sides and the dust removal channel 211. They undergo primary filtration through the corresponding set of ventilation filter plates 222, and the filtered material is retained in the corresponding dust storage bin. This achieves primary and effective filtration of dust and particles. After filtration, the material is introduced into the secondary outer frame 31 through the corresponding dust removal groove 231, the connecting suction pipe 2313, and the third pipe 311. It then undergoes secondary filtration through the filter core 33, effectively improving the filtration and dust removal effect of dust and particles. The inner cylinder 23 of the primary cleaning system has a waste removal groove 2321 that communicates with the waste removal groove 232 at one end near the dust suction groove 2311. A second through groove 2322 is provided between the two waste removal grooves 2321 to connect the two waste removal grooves 2321. An air injection pipe 2323 and a liquid injection pipe 2326 are fixedly fastened to the ends of the two waste removal grooves 2321 respectively.

[0032] A first valve 2324 is fixedly installed at one end of the air injection pipe 2323 away from the primary cleaning inner cylinder 23. A first pipe 2325 is fixedly installed at one end of the first valve 2324 away from the air injection pipe 2323. A connecting air hose 7 is fixedly installed at one end of the first pipe 2325 away from the first valve 2324. In use, the end of the connecting air hose 7 is connected to the output port of the drying air output pump mechanism.

[0033] A second valve 2327 is fixedly installed at one end of the injection pipe 2326 away from the inner cylinder 23. A second pipe 2328 is fixedly installed at one end of the second valve 2327 away from the injection pipe 2326. A connecting hose 71 is fixedly installed at one end of the second pipe 2328 away from the second valve 2327. In use, the end of the connecting hose 71 is connected to the output port of the cleaning fluid output pump mechanism.

[0034] A rotating shaft 24 is fixedly installed at the middle of the end of the primary dust collector 22 away from the secondary dust collector 3. A driven worm gear 241 is fixedly installed on the outer side of the rotating shaft 24. A drive worm 242 is meshed with the outer side of the driven worm gear 241. The drive worm 242 is rotatably mounted on the mounting bracket 1. By controlling the rotation of the drive worm 242, the driven worm gear 241 is driven to rotate, thereby controlling the rotating shaft 24 to drive the primary dust collector 22 to rotate. The primary dust collector 22 rotates between the primary dust collector outer cylinder 21 and the primary dust collector inner cylinder 23, flexibly adjusting the position of multiple sets of dust storage slots 221 so that each set of dust storage slots 221 corresponds to the dust removal channel 211 and the dust removal groove 231. This allows multiple sets of ventilation filter plates 222 to correspond sequentially to the dust removal channel 211 and the dust removal groove 231, facilitating primary filtration of the inhaled plastic dust and particles through different sets of ventilation filter plates 222, preventing the filtered material from clogging the ventilation filter plates 222.

[0035] A drive motor 243 is fixedly installed at one end of the mounting bracket 1 near the drive worm 242. The drive end of the drive motor 243 is fixedly installed at the top end of the drive worm 242. The drive worm 242 is rotated by controlling the start of the drive motor 243.

[0036] After one set of ventilation filter plates 222 has been filtering for a long time, the dust collection bin accumulates a large amount of filter material, causing blockage of the ventilation filter plate 222. At this time, it is necessary to rotate and replace it with the next set of ventilation filter plates 222. At the same time, the dust collection channel 221 that originally stored a large amount of filter material corresponds to the waste removal channel 212 and the waste removal groove 232. At this time, the cleaning fluid output pump mechanism and the second valve 2327 can be controlled to be turned on, and the first valve 2324 can be turned off. The cleaning fluid is introduced into the two waste removal channels 2321 through the connecting hose 71, the second pipe 2328, and the injection pipe 2326, and then into the waste removal groove 232. Subsequently, it enters the corresponding dust collection channel 221 to remove the accumulated filter material. The accumulated filter material is cleaned and discharged into two waste removal frames 6 through the waste removal channel 212. It is then introduced into the treatment mechanism 4 through the waste removal pipe head 61, the waste removal main pipe 62, and the installation pipe 63 for automatic cleaning and discharge of the filter material, eliminating the need for manual cleaning. After the filter material is cleaned and discharged, the drying air output pump mechanism and the first valve 2324 are activated, and the second valve 2327 is closed. The drying air is introduced into two waste removal channels 2321 through the liquid connecting hose 71, the second pipe 2328, and the liquid injection pipe 2326, and then enters the waste removal groove 232. Subsequently, it enters the corresponding dust storage channel 221 to dry the corresponding ventilation filter plate 222, facilitating its continued use in the future.

[0037] The processing mechanism 4 includes a processing frame 41. A fifth pipe 42 is fixedly installed at the middle of one end of the processing frame 41. The end of the fifth pipe 42 and the end of the installation pipe 63 away from the waste removal main pipe 62 are fixedly installed to connect and fix the processing mechanism 4 and the installation pipe 63. A drain pipe 43 is fixedly installed at the bottom side of the processing frame 41. An exhaust pipe 411 is fixedly installed at the top of the processing frame 41 away from the fifth pipe 42. A fourth valve 431 is fixedly installed at the end of the drain pipe 43 away from the processing frame 41. A recovery pipe 432 is fixedly installed at the end of the fourth valve 431 away from the drain pipe 43. A filter base plate 44 is fixedly installed at the bottom inner side of the processing frame 41. A filter base plate 44 is fixedly installed at the top inner side of the processing frame 41. A filter top plate 45 is fixedly installed. The fifth pipe 42 is located between the filter bottom plate 44 and the filter top plate 45. A cover 46 is detachably installed on the side of the processing frame 41 away from the fifth pipe 42. The filtered material discharged after cleaning is introduced into the processing frame 41 through the fifth pipe 42 and placed between the filter bottom plate 44 and the filter top plate 45. After being filtered by the filter bottom plate 44 and the filter top plate 45 respectively, the gas is discharged through the exhaust pipe 411. The filtered liquid is left at the bottom of the processing frame 41. By opening the fourth valve 431, the filtered liquid is discharged through the recovery pipe 432 for recycling. The filtered material is left on the filter bottom plate 44. The filtered material can be cleaned out later by opening the cover 46.

[0038] Working principle: When in use, the entire dust removal device is fixedly installed at a suitable position in the plastic woven bag production and cutting station using the mounting top frame 1. During specific installation and use, the length and structural type of the dust suction frame 5 are selected according to the different plastic woven bag cutting stations. After the entire device is installed, the dust suction ports at the bottom of the two dust suction frames 5 correspond to the cutting parts of the woven bags, which facilitates the precise suction of plastic dust and particles generated at the cutting parts of the woven bags. The end of the dust suction hose 34 is connected to the suction end of the dust suction system, the end of the connecting air hose 7 is connected to the output port of the drying air output pump mechanism, and the end of the connecting liquid hose 71 is connected to the output port of the cleaning liquid output pump mechanism. The vacuum system and the third valve 32 are activated, creating a negative pressure at the bottom of the two vacuum frames 5. This allows for the precise suction of plastic dust and particles generated from the cut parts of the woven bag. The dust and particles are drawn into a corresponding set of dust storage channels 221 through the vacuum frames 5 on both sides and the dust removal channel 211. They undergo primary filtration through a corresponding set of ventilation filter plates 222, and the filtered material is stored in the corresponding dust storage bin. This provides primary and effective dust removal for the dust and particles. After filtration, the material is introduced into the secondary outer frame 31 through the corresponding dust removal groove 231, the connecting suction pipe 2313, and the third pipe 311. It then undergoes secondary filtration through the filter core 33, effectively improving the dust removal effect. When one set of ventilation filter plates 222 has been filtering for a long time, the dust collection bin stores a lot of filter material, which causes blockage of the ventilation filter plate 222. At this time, it is necessary to rotate and replace it with the next set of ventilation filter plates 222. By controlling the drive worm gear 242 to rotate, the driven worm wheel 241 is driven to rotate, thereby controlling the rotating shaft 24 to drive the primary filter cylinder 22 to rotate. The primary filter cylinder 22 rotates between the primary filter outer cylinder 21 and the primary filter inner cylinder 23, flexibly adjusting the position of multiple sets of dust collection slots 221 so that each set of dust collection slots 221 corresponds to the dust removal channel 211 and the dust removal groove 231. This allows multiple sets of ventilation filter plates 222 to correspond to the dust removal channel 211 and the dust removal groove 231 in sequence, which facilitates the primary filtration of plastic dust and particles by different sets of ventilation filter plates 222, and prevents the filter material generated by filtration from causing blockage of the ventilation filter plates 222. Simultaneously, the dust storage trough 221, which originally stored a large amount of filter material, corresponds to the waste removal trough 212 and the waste removal recess 232. At this time, the cleaning fluid output pump mechanism and the second valve 2327 can be controlled to open, and the first valve 2324 can be closed. The cleaning fluid is introduced into the two waste removal troughs 2321 through the connecting hose 71, the second pipe 2328, and the injection pipe 2326, and then enters the waste removal recess 232. Subsequently, it enters the corresponding dust storage trough 221, and the accumulated filter material is cleaned through the waste removal trough 212 and discharged into the two waste removal frames 6. The filter material is then discharged through the waste removal pipe head 61 and the waste removal... The main pipe 62 and the installation pipe 63 are introduced into the treatment mechanism 4 for automatic cleaning and discharge of the filtered material, which does not require manual cleaning. After the filtered material is cleaned and discharged, the drying air output pump mechanism and the first valve 2324 are turned on and the second valve 2327 is turned off. The drying air is introduced into the two waste removal channels 2321 through the liquid connecting hose 71, the second pipe 2328 and the liquid injection pipe 2326, and then enters the waste removal groove 232. Subsequently, it enters the corresponding dust storage channel 221 to dry the corresponding ventilation filter plate 222, so that the ventilation filter plate 222 can be used again in the future. The filtered material discharged from the cleaning process is introduced into the processing frame 41 through the fifth pipe 42 and placed between the filter bottom plate 44 and the filter top plate 45. After being filtered by the filter bottom plate 44 and the filter top plate 45 respectively, the gas is discharged through the exhaust pipe 411. The filtered liquid is left at the bottom of the processing frame 41. By opening the fourth valve 431, the filtered liquid is discharged through the recovery pipe 432 for recycling. The filtered material is left on the filter bottom plate 44. The filtered material can be cleaned out later by opening the cover 46.
