Abstract
Description
Technical fields:
[0001] This utility model relates to the field of yarn manufacturing and processing technology, and more specifically to a dust collection device for a carding machine. Background technology:
[0002] Carding machines are used to process cotton and chemical fibers and belong to textile machinery. Carding is an important step in the spinning process.
[0003] In a carding machine, before the fiber material enters the licker-in roller, it throws out impurities, short fibers, and some ungrasped fibers generated during the carding process. These are then removed by a suction pipe. However, existing suction pipes are directly fixed to the frame, and the suction port is in a fixed position. The distance between the suction pipe and the raw materials such as cotton or chemical fibers conveyed on the licker-in roller is relatively large, making it impossible to timely absorb the thrown material. This affects the suction effect and efficiency. Utility Model Content:
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dust collection device for a carding machine. Its elongated suction channel is located near the lower rear part of the licker-in roller, allowing it to adsorb debris, short fibers, and other materials at the ejection position of the licker-in roller at close range. Moreover, the position of the transverse suction connecting pipe can be adjusted to change the suction position of the elongated suction channel, ensuring that it is in the optimal position to adsorb the impurities and other materials ejected by the licker-in roller while maintaining the distance between it and the carded fiber material, thus preventing the adsorption of too much fiber material (processing material).
[0005] The solution of this utility model to the aforementioned technical problem is:
[0006] A dust collection device for a carding machine includes a transverse suction connecting pipe installed in the main body of the carding machine. The transverse suction connecting pipe is located below the rear side of the licker-in roller. A rotating shaft is fixed in the middle of the two end plates of the transverse suction connecting pipe. The rotating shaft is movably connected to the left and right side plates of the main body of the carding machine through bearings.
[0007] The upper part of the transverse suction connecting pipe is formed with two side plates extending obliquely in opposite directions. The upper ends of the two side plates are formed together to form a top connecting part. The middle part of the top connecting part is formed with a long suction groove extending to the left and right. The long suction groove is opposite to the lower part between the licker-in roller and the conveying guide roller set in the carding machine body behind the licker-in roller.
[0008] One of the rotating shafts has a central suction hole formed in the middle, which communicates with the central hole of the corresponding end plate of the transverse suction connecting pipe and is connected to the transverse suction connecting pipe. The outer end of this rotating shaft extends out of the corresponding side plate of the carding machine body and is movably connected to the external suction connecting pipe. The outer end of the other rotating shaft extends out of the corresponding side plate in the carding machine body, and a fixing bracket is fixed on the outer side wall of this side plate.
[0009] Below the transverse suction connecting pipe is a lower support frame. The bottom of the lower support frame is fixed to the top surface of the bottom plate of the carding machine body. A left-right extending feeding block is fixed on the top surface of the top fixing plate of the lower support frame. A left-right extending arc-shaped slot is formed in the middle of the top surface of the feeding block. The lower part of the lower tube body of the transverse suction connecting pipe is in the arc-shaped slot.
[0010] A limiting gear is fixed on the outer wall of the rotating shaft at the left end of the transverse suction connecting pipe. A fixing frame is fixed on the outer wall of the side plate of the carding machine body at this rotating shaft. A through hole is formed in the middle of the top plate of the fixing frame. The positioning rod is inserted into the through hole. The outer wall of the positioning rod is close to or tightly attached to the inner wall of the through hole. A radially extending edge is fixed on the outer wall of the bottom end of the positioning rod. A positioning part is formed at the bottom end of the positioning rod and is inserted into the corresponding tooth groove of the limiting gear. The top of the positioning rod extends out of the top surface of the top plate of the fixing frame and is fixed with a gripping part. A compression spring is inserted into the lower part of the positioning rod. One end of the spring is applied to the top surface of the radially extending edge, and the other end is applied to the bottom surface of the top plate of the fixing frame.
[0011] The outstanding effect of this utility model is:
[0012] Its elongated suction channel is located near the rear and lower part of the licker-in roller, allowing it to adsorb debris, short fibers, and other materials at the ejection position of the licker-in roller at close range. Moreover, the position of the transverse suction connecting pipe can be adjusted to change the suction position of the elongated suction channel, ensuring that it is in the optimal position to adsorb impurities and other materials ejected by the licker-in roller while maintaining the distance between it and the combed fiber material to prevent the adsorption of too much fiber material.

[0017] For example, see below. Figures 1 to 4 As shown, a dust collection device for a carding machine includes a transverse suction connecting pipe 10 installed in the main body of the carding machine. The transverse suction connecting pipe 10 is located below the rear side of the licker-in roller 100. A rotating shaft 11 is fixed in the middle of the left and right end plates of the transverse suction connecting pipe 10. The rotating shaft 11 is movably connected to the left and right end plates of the main body of the carding machine through bearings.
[0018] The transverse suction connecting pipe 10 includes a lower pipe body 15 with an arc-shaped cross-section. The upper front end and the upper rear end of the lower pipe body 15 are both formed with side plate parts 12. The two side plate parts 12 extend obliquely towards each other. The upper ends of the two side plate parts 12 are formed together to form a top connecting part 13. The middle part of the top connecting part 13 to the upper part of the rear side plate part 12 is formed with a long suction groove 14 extending to the left and right. The long suction groove 14 is located between the licker-in roller 100 and the conveying guide roller 200 provided in the carding machine body behind the licker-in roller 100. The long suction groove 14 is close to the rear part of the licker-in roller 100.
[0019] Furthermore, one of the rotating shafts 11 has a central suction hole formed in the middle, which communicates with the central hole of the corresponding end plate of the transverse suction connecting pipe 10 and the inner cavity of the transverse suction connecting pipe 10. The outer end of this rotating shaft 11 extends out of the corresponding side plate of the carding machine body and is movably connected to the outer suction connecting pipe 20. The outer end of the other rotating shaft 11 extends out of the corresponding side plate in the carding machine body, and a fixing bracket 30 is fixed on the outer side wall of this side plate.
[0020] Below the transverse suction connecting pipe 10, a lower support frame 40 is provided. The bottom of the lower support frame 40 is fixed to the top surface of the bottom plate of the carding machine body. A left-right extending feeding block 41 is fixed to the top surface of the top fixed plate of the lower support frame 40. A left-right extending arc-shaped slot 42 is formed in the middle of the top surface of the feeding block 41. The lower part of the lower tube body 15 of the transverse suction connecting pipe 10 is located in the arc-shaped slot 42. A self-lubricating arc-shaped block 43 is fixed to the bottom surface of the arc-shaped slot 42. Multiple arc-shaped grooves 44 are formed on the inner side wall of the self-lubricating arc-shaped block 43. Multiple arc-shaped guide blocks 151 are fixed to the outer side wall of the lower tube body 15. The arc-shaped guide blocks 151 are inserted into the corresponding arc-shaped grooves 44 and cooperate with the arc-shaped grooves 44. The outer wall surface of the arc-shaped guide block 151 is in close contact with the inner wall surface of the arc-shaped groove 44, and the side wall of the arc-shaped guide block 151 is in close contact with or close to the corresponding inner side wall of the arc-shaped groove 44.
[0021] The material discharge block 41 and the self-lubricating arc block 43 support the transverse suction connection pipe 10, while the arc groove 44 and the arc guide block 151 cooperate to limit the left and right movement of the transverse suction connection pipe 10 during adjustment and rotation, preventing it from moving.
[0022] Furthermore, a limiting gear 1 is fixed on the outer wall of the rotating shaft 11 at the left end of the transverse suction connecting pipe 10. A fixing frame 30 is fixed on the outer wall of the side plate of the carding machine body at this rotating shaft 11. A through hole 32 is formed in the middle of the top plate of the fixing frame 30. The positioning rod 33 is inserted into the through hole 32. The outer wall of the positioning rod 33 is close to or tightly attached to the inner wall of the through hole 32. A radially extending edge 331 is fixed on the outer wall of the bottom end of the positioning rod 33 (the radially extending edge 331 is located below the top plate of the fixing frame 30). The bottom end of the positioning rod 33 is formed with a positioning part 332 (the cross-section of which is triangular), which is inserted into the corresponding tooth groove of the limiting gear 1. The top of the positioning rod 33 extends out of the top surface of the top plate of the fixing frame 30 and is fixed with a gripping part (the bottom surface of the gripping part has a screw hole in the middle, and the top of the positioning rod 33 is screwed into the screw hole to achieve connection). The compression spring 34 is inserted in the lower part of the positioning rod 33, with one end bearing on the top surface of the radially extending edge 331 and the other end bearing on the bottom surface of the top plate of the fixing frame 30.
[0023] Furthermore, a central intake hole is formed in the middle of the rotating shaft 11 on the right side, an outer radial extension edge is formed on the outer wall of the right end of the rotating shaft 11, a second outer radial extension edge is formed on the outer wall of one end of the external intake connecting pipe 20, the outer radial extension edge and the second outer radial extension edge are inserted into the same external connecting sleeve 21, an inner radial extension annular portion is formed on the inner wall of the left end of the external connecting sleeve 21, a self-lubricating layer 22 is fixed on the inner wall of the annular portion, the rotating shaft 11 is inserted into the inner radial extension annular portion, the side wall of the self-lubricating layer 22 is close to or near the outer wall of the rotating shaft 11, a right annular sleeve 23 is fixedly connected to the right end face of the external connecting sleeve 21 by bolts, the end of the external intake connecting pipe 20 is inserted into the right annular sleeve 23, a second self-lubricating layer 24 is fixed on the inner wall of the right annular sleeve 23, the second self-lubricating layer 24 is close to or near the outer wall of the end of the external intake connecting pipe 20.
[0024] An elastic sealing ring 25 is fixed to the end face of the external air intake connection pipe 20, which is clamped between the end face of the external air intake connection pipe 20 and the corresponding end face of the corresponding rotating shaft 11. This elastic sealing ring 25 provides a certain damping effect to the rotating shaft 11 on the right side when it rotates, but does not affect its rotation.
[0025] A spring 2 is sleeved on the outer side of the end of the external air intake connecting pipe 20. One end of the spring 2 is applied to the inner end face of the right annular sleeve 23, and the other end is applied to the right end face of the second outer radial extension side. A self-lubricating pad 3 is fixed on the left end face of the outer radial extension side, and the left end face of the self-lubricating pad 3 is pressed against the right end face of the inner radial extension annular part.
[0026] In this embodiment, it can be installed in a carding machine. The positioning rod 33 can be pulled upward to move the positioning part 33 out of the corresponding tooth groove of the limiting gear 1. Then, the limiting gear 1 is rotated to rotate the transverse suction connecting pipe 10, changing the position of its elongated suction channel 14 between the licker-in roller 100 and the conveying guide roller 200 set in the carding machine body behind the licker-in roller 100. At the same time, when the transverse suction connecting pipe 10 is rotated, the distance between the elongated suction channel 14 and the raw material conveyed between the licker-in roller 100 and the conveying guide roller 200 is also changed. It can be adjusted to both absorb the debris at the ejection position and reduce the probability of absorbing the conveyed raw material, thus achieving the optimal position adjustment.
[0027] Furthermore, the side plate of the carding machine body at the corresponding position has an observation through hole and a transparent plate is fixed thereon. The transparent plate covers the observation through hole. When adjusting the transverse suction connecting pipe 10, the internal adsorption effect can be observed through the transparent plate (this transparent plate can also be opened). After the adjustment is completed, the positioning rod 33 is released, and the elastic reset of the compression spring 34 causes the positioning part 332 to be inserted into the corresponding tooth groove of the limiting gear 1 to achieve positioning. When the positioning part 332 cannot be inserted into the corresponding tooth groove, the limiting gear 1 is rotated slightly (the distance is only one tooth groove) so that it can be inserted into the adjacent tooth groove to achieve positioning. At this time, the fine adjustment has basically no impact on the dust suction.
[0028] Meanwhile, during use, the other end of the external suction connection pipe 20 in this embodiment is fixed in the vacuum cleaner, where it performs the vacuuming function.
[0029] In this embodiment, when the raw materials being processed are different, the ejection position of the spiked roller 100 and the thickness of the raw material conveying will change. In this case, the adjustment can be made again in the manner described above.
[0030] In this embodiment, because the elongated air intake channel 14 is close to the rear of the licker-in roller 100, it can quickly and timely adsorb impurities, short fibers and other materials at the ejection position of the licker-in roller, resulting in high adsorption efficiency. Moreover, the position of the transverse air intake connecting pipe 10 can be adjusted to change the air intake position of the elongated air intake channel 14, ensuring that it is in the optimal position to adsorb impurities and other materials ejected by the licker-in roller 100, while maintaining the distance between it and the combed fiber material (raw material), thus preventing the adsorption of too much fiber material.
[0031] After a certain period of operation, the right annular sleeve 23 needs to be separated from the outer connecting sleeve 21 for observation and maintenance of its internal parts.
[0032] Furthermore, when the external suction connecting pipe 20 needs to be replaced, it is only necessary to separate the right annular sleeve 23 from the outer connecting sleeve 21, and then the external suction connecting pipe 20 can be separated from the right rotating shaft 11, which facilitates the disassembly, replacement and maintenance of the external suction connecting pipe 20. Moreover, when there are cotton fibers or other debris entangled between the right annular sleeve 23 and the rotating shaft 11 and the end of the external suction connecting pipe 20, the right annular sleeve 23 can also be separated from the outer connecting sleeve 21 to remove the cotton fibers and other debris inside, which is very convenient.
[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
