Description

Technical Field

[0001] The invention relates to the technical field of textile processing, in particular to a waste gas recovery device for combing pile for long-haired carpets. Background Art

[0002] Long-haired carpets are usually made of materials such as animal hair, plant hemp or synthetic fibers, and are processed through fine weaving and cutting. The selection and processing of these materials make long-haired carpets soft and comfortable to walk on. Long-haired carpets also have certain anti-slip functions, which can reduce the risk of family members falling due to slippery floors.

[0003] During the processing of long-haired carpets, dust may fly. This is mainly because the dust, hair, dandruff and other debris accumulated in the carpet fibers are stirred during combing, generating a large amount of organic waste gas and releasing it into the air. The mixed dust and fluff are easily inhaled by production personnel, affecting their health. For this reason, we propose a combing waste gas recovery equipment for long-haired carpets to solve the above problem. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 8The present invention provides a technical solution: a combing waste gas recovery device for long-haired carpets, comprising a combing box 1, an auxiliary combing mechanism 2 arranged inside the combing box 1, and an exhaust gas extraction box 3 installed outside the combing box 1, a pair of positioning plates are installed on the top of the combing box 1, and a sealing plate can be clamped on the positioning plate, and slide grooves are provided on the side walls at both ends of the combing box 1, and the auxiliary combing mechanism 2 is movably clamped inside the slide groove and can be adjusted according to the material of the carpet, and rectangular grooves are provided on both sides of the combing box 1, and the rectangular grooves are symmetrically arranged on both sides of the combing box 1, and the exhaust gas extraction box 3 is clamped inside the rectangular groove, and the exhaust hole of the exhaust gas extraction box 3 is connected to the external air pressure equipment;

[0034] A pair of positioning frames 4 are installed inside the combing box 1. A conveying roller 41 is rotatably provided inside the positioning frames 4. The positioning frames 4 are located on both sides of the auxiliary combing mechanism 2. When the long-haired carpet needs to be combed, one end of the positioning frames 4 can be clamped on the limiting roller 11. As the limiting roller 11 rotates, the carpet can be driven to move inside the combing box 1. Under the action of the auxiliary combing mechanism 2 and the exhaust gas extraction box 3, the pile surface of the carpet can be combed and dusted, which can reduce the mixed debris and dirt in the carpet.

[0035] like Figure 3 As shown, the fluff on the surface of the long-haired carpet is easily messed up and tangled under the action of external force during the transmission process. The auxiliary combing mechanism 2 includes a pair of transmission plates 21, and positioning rods are installed on the outer sides of the transmission plates 21, and the positioning rods are movably clamped in the inside of the slide groove. A pair of positioning shafts 22 are installed between the transmission plates 21, and the positioning shafts 22 are arranged in parallel. A plurality of fixed tubes 26 are installed on the top of the positioning shafts 22, and a movable sleeve 23 is sleeved on the top of the fixed tube 26. A pair of elastic rods 231 are installed at the bottom of the movable sleeve 23, and the elastic rods 231 are clamped at both ends of the fixed tube 26;

[0036] The movable sleeves 23 are symmetrically arranged in pairs at the top of the auxiliary combing mechanism 2. A support plate 24 is installed between a pair of movable sleeves 23. A combing shaft 25 is clamped on the support plate 24. The combing shaft 25 is rectangular and elastic. Tooth grooves are provided at both ends of the combing shaft 25. During the transmission process, the position of the auxiliary combing mechanism 2 can be controlled and can be adjusted according to the length of the pile surface. During the transmission process, the combing shaft 25 can comb the pile on the surface. Impurities attached to the surface of the pile can also be quickly cleaned under the action of the tooth grooves, which can reduce the debris remaining in the carpet.

[0037] like Figure 4As shown, during the transmission process, the carpet is prone to accumulation of debris that is inconvenient to be discharged. A plurality of arc grooves are provided on the side wall of the fixed tube 26, and an annular shaft 261 is fixedly connected to the inner wall of the fixed tube 26. The annular shaft 261 is evenly arranged in an array inside the fixed tube 26 and is elastic. The outer wall of the annular shaft 261 is in contact with the inner wall of the movable sleeve 23, and a conical pressing block 27 is installed at the bottom of the inner wall of the fixed tube 26. During the transmission process, the conical pressing block 27 can be squeezed between the expansion ball 281. The deformation of the expansion ball 281 can push the carpet to stretch, and can make the pile surface slightly away from the combing shaft 25, so as to facilitate the rapid discharge of the residual debris inside along the airflow, thereby ensuring the cleaning effect of the equipment and reducing the accumulation of residual debris caused by long-term processing.

[0038] like Figure 5 As shown, in order to facilitate chip removal during carpet transmission, a limit ring 28 is installed on the top of the movable sleeve 23, and an expansion ball 281 is clamped inside the limit ring 28. The bottom of the expansion ball 281 is against the top of the conical pressure block 27, and a plurality of elastic sheets 282 are fixedly connected to the top of the expansion ball 281. The elastic sheets 282 are provided with a plurality of semicircular grooves. When the expansion ball 281 is deformed, the elastic sheets 282 can be pressed against the bottom of the carpet, and the contacted fluff can be expanded and combed outward, thereby reducing the occurrence of knots during the lifting process.

[0039] like Figure 6 As shown, in the process of waste gas separation, the screen plate is prone to blockage, which affects the separation efficiency of the equipment. The waste gas extraction box 3 is located on one side of the combing box 1 and is open. A sealing baffle 31 is installed inside the waste gas extraction box 3. A plurality of air inlet grooves are provided on the surface of the sealing baffle 31. Separation liquid is stored at the bottom of the waste gas extraction box 3, and the separation liquid is generally clean water. A rotating shaft 32 is rotatably provided at the bottom of the waste gas extraction box 3. The rotating shaft 32 is located inside the separation liquid, and the movable screen plate 33 can be circulated in the separation liquid for soaking and cleaning, thereby reducing the residue of debris and dust on the surface, and can effectively extend the maintenance cycle of the equipment.

[0040] A reset ring 34 is rotatably provided on the side wall at the top of the exhaust gas extraction box 3. The reset ring 34 is symmetrically arranged. A movable gear 36 is rotatably provided inside the reset ring 34. The movable gear 36 is concentrically arranged with the reset ring 34. A transmission rod 361 is installed between the movable gears 36. A movable sieve plate 33 is movably provided on the rotating shaft 32 and the transmission rod 361. The movable sieve plate 33 is elastic and grid-shaped. When the external air pressure equipment is operated, the dusty exhaust gas can enter the exhaust gas extraction box 3 along the air flow. Under the blocking effect of the wetted movable sieve plate 33, the floating particles and debris in the exhaust gas can be collected, thereby playing a role in dust reduction.

[0041] like Figure 7 and Figure 8As shown, in order to prevent the problem of excessive accumulation of dust and debris on the movable screen plate 33, a clamping ring 341 is clamped inside the reset ring 34, and a toggle shaft 342 is hinged inside the clamping ring 341. One end of the toggle shaft 342 is against the inside of the outer teeth of the movable gear 36. A plurality of limiting protrusions are movably inserted inside the exhaust gas extraction box 3, and a positioning slot 37 is opened on the surface of the movable gear 36, and the limiting protrusion can be movably clamped inside the positioning slot 37.

[0042] A blocking frame 35 is installed on the outer wall of the reset ring 34. The length of the blocking frame 35 can be adjusted. The blocking frame 35 can be against the top of the carpet, and the top of the carpet can be squeezed between the blocking frame 35, so that the blocking frame 35 can drive the reset ring 34 to rotate, thereby moving the dial shaft 342 to make it clamped between the next outer teeth of the movable gear 36, and with the help of the positioning slot 37 and the limiting protrusion, the movable gear 36 is positioned, driving the transmission rod 361 to rotate, so that the movable sieve plate 33 can move in the separation liquid, and the separation liquid can be replaced regularly, reducing the labor intensity of maintenance and cleaning.

[0043] like Figure 2 As shown, in order to ensure the stability of carpet transmission, a plurality of compression shafts 42 are installed inside the positioning frame 4. The bottom of the compression shaft 42 is arc-shaped and abuts against the conveying roller 41, which is used for auxiliary cleaning of the surface of the conveying roller 41. During the transmission process, the rubber surface of the carpet can abut against the surface of the conveying roller 41. During the transmission process, the lint and silk threads remaining on the rubber surface are easy to adhere to the surface of the conveying roller 41 and are prone to winding. Long-term use will cause the surface of the carpet to be uneven during transportation. With the help of the compression shaft 42, the silk threads wound on the conveying roller 41 can be collected, thereby reducing the unevenness of the carpet during transmission and reducing the impact on subsequent cleaning.

[0044] like Figure 1 As shown, a movable frame is installed at one end of the combing box 1, and a limiting roller 11 is rotatably provided inside the movable frame. A clamping frame is installed at both ends of the combing box 1, and a guide roller 12 is rotatably provided on the clamping frame. The guide roller 12 and the limiting roller 11 are both used for limiting the transmission of the carpet, which can ensure the stability of the carpet transmission, and the limiting roller 11 is used for temporarily collecting the carpet.

[0045] Working principle: first, when it is necessary to comb the long-haired carpet, one end of the carpet can be clamped on the limiting roller 11. As the limiting roller 11 rotates, the carpet can be driven to move inside the combing box 1. The pile surface of the carpet can be combed and dusted under the action of the auxiliary combing mechanism 2 and the exhaust gas extraction box 3, which can reduce the debris and dirt mixed in the carpet. As the carpet is transmitted inside the equipment, the position of the auxiliary combing mechanism 2 can be adjusted according to the pile on the surface of the carpet, which is convenient for combing the pile and preventing knotting and confusion. As the carpet is being transmitted, the movable sleeve 23 can be intermittently squeezed, so that the combing shaft 25 moves with the movable sleeve 23, and the combing shaft 25 can be against one side of the pile surface of the carpet to quickly clean and shake off the debris inside the pile. As the transmission process, the conical pressing block 27 can be squeezed between the expansion ball 281, and the deformation of the expansion ball 281 can push the carpet to stretch, which can make the pile surface slightly away from the combing shaft 25, so that the debris remaining inside can be quickly discharged along the airflow, thereby ensuring the cleaning effect of the equipment.

[0046] Then, during the transportation process, the rubber surface of the carpet can be against the surface of the conveying roller 41. During the transportation process, the lint and silk threads remaining on the rubber surface are easy to adhere to the surface of the conveying roller 41 and are easy to be wound. After long-term use, the surface of the carpet will be uneven during transportation. The compression shaft 42 can be used to collect the silk threads and the like wound on the conveying roller 41 for subsequent unified processing.

[0047] Finally, when waste gas and dust are generated, as the external air pressure equipment operates, the dusty waste gas can follow the airflow into the waste gas extraction box 3, and the floating particles and debris in the waste gas can be collected under the blocking effect of the wetted movable screen plate 33, thereby playing a role in dust reduction. As the top of the carpet can be squeezed between the blocking frame 35, the blocking frame 35 can drive the reset ring 34 to rotate, thereby moving the toggle shaft 342 so that it is clamped between the next outer teeth of the movable gear 36. The positioning slot 37 and the limiting protrusion cooperate to position the movable gear 36, driving the transmission rod 361 to rotate, so that the movable screen plate 33 can move in the separation liquid to play a cleaning role, thereby ensuring the recovery efficiency of the equipment.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
