Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, in particular to a cotton opener for textile production. Background Art

[0002] The cotton opener uses two rotating porcupine beaters to open the cotton. When in use, the blades on the porcupine beaters can hit all lateral points of the cotton layer fed into the beaters within one rotation of the beaters, thereby opening the cotton. However, the existing porcupine beater blades are fixed, which easily causes cotton or fibers to be entangled at the roots of the blades, making it difficult to clean and affecting the quality of cotton opening.

[0003] Chinese invention patent CN117626482A discloses a mixed cotton opening machine for textile production, which is provided with a variable porcupine beater for cleaning residual cotton. After the cotton opening is completed, the power supply of the mixed opening motor is cut off, and then the electric telescopic rod is started. At this time, the electric telescopic rod pulls the sliding rod outward through the bracket. At this time, the sliding rod drives the wave guide rail to move to the left, so that the pulley whose original cotton opening blade contacts the wave crest of the wave guide rail contacts the valley peak of the wave guide rail, thereby retracting the cotton opening blade into the inside of the rotating roller, so that the cotton originally entangled at the root of the cotton opening blade is detached. Compared with the existing cotton opener, the present invention can automatically clean the cotton entangled at the root of the cotton opening blade after the cotton opening is completed, without manual cleaning, and is more convenient to use and cleans thoroughly to avoid cotton residue, and the cotton opening quality is better.

[0004] In the prior art, the beater is set to a retractable structure so that the cotton wrapped around the beater can be removed when the beater is retracted. The retraction of the beater in the reference document needs to be achieved through a wave track, and the retraction of the beater needs to move a certain distance. Therefore, it is necessary to open a groove on the roller for the beater to move, which makes it easier for cotton to enter the groove and cause blockage. Summary of the invention

[0008] Preferably, a flange is provided outwardly at the upper end of the fixed tube, and the diameter of the flange is equal to the inner diameter of the movable tube. A tube support is integrally connected to the end of the movable tube, and the inner side surface of the tube support contacts the outer surface of the fixed tube. When the movable tube is pushed by high-pressure gas, the tube support and the flange are sealed, and when the inner surface of the tube support contacts the outer surface of the flange, the movement of the movable tube is restricted.

[0009] Preferably, a sealing sheet is provided in the movable tube away from the tube support, and the interior of the movable tube is divided into two cavities of different sizes by the sealing sheet. The fixed tube is inserted into the large cavity, and a thread is provided on the inner wall of the small cavity in the movable tube to form a threaded hole. The beater is placed in the threaded hole, and a blade is provided on the opposite side of the beater.

[0010] Preferably, the tail of the beater is connected to a connecting block, a groove is centrally formed on the upper surface of the connecting block, a hole is formed at the tail of the beater, a torsion spring is arranged in the hole, the beater is rotatably connected to the groove of the connecting block through the torsion spring, a pair of beaters are arranged in a scissors shape in the groove of the connecting block, the upper end of the outer surface of the beater is an inclined surface, and the width of the inclined surface gradually decreases from top to bottom, and the length of the inclined surface is half the length of the beater.

[0011] Preferably, a rotating joint is provided at one end of the pressure cylinder connected to the air pipe, the air pipe is connected to the end of the pressure cylinder through the rotating joint, and a counterweight block is provided inside the other end of the pressure cylinder.

[0012] Preferably, bearing seats are provided at both ends of the porcupine roller, and the porcupine roller is rotatably connected in the cotton opening box through the bearing seats. A first motor is installed outside the cotton opening box, and the output end thereof passes through the cotton opening box and is connected to one end of the porcupine roller.

[0013] Preferably, a feed hopper is provided on the upper surface of the cotton opening box, and the bottom of the feed hopper is located directly above the pair of porcupine beaters.

A second motor is installed on the outer side of the conveying box, and the driving end of the second motor is connected to one end of the crawler conveyor.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the movable tube is retracted by suction to pull the beater into the porcupine drum, the beater arranged in a scissor shape is closed. This design can directly cut the cotton wrapped around the beater. Compared with the traditional method, manual cleaning is not required, which greatly improves the cleaning efficiency. Furthermore, since the beater can be retracted inside the drum, the cotton wrapped around the beater is easier to withdraw from between the two beaters, reducing the cotton residue on the beater, further improving the thoroughness of cleaning, and the upper end of the outer surface of the beater is an inclined surface, and the width of the inclined surface gradually decreases from top to bottom, which is conducive to the retraction of the beater into the porcupine drum, and the beater arranged in a scissor shape is easier to close through the through hole extrusion to break the wrapped cotton through the blade. The above design does not need to open an excessively long groove, thereby avoiding cotton wool being blocked in the groove and causing the cleaning mechanism to be paralyzed, and gas propulsion can make multiple beaters synchronously extend and retract to complete the cleaning, without the need to use multiple propulsion components, thereby reducing costs.

[0016] The traditional cleaning method may require stopping the equipment and disassembling it to clean the entangled cotton. However, the design of the retractable beater in the present invention allows cleaning operations to be performed during the operation of the equipment. For example, suction operations are performed during the intervals between equipment operations to retract the beater for cleaning, thereby reducing the time the equipment is stopped for cleaning and improving production efficiency.

[0017] The porcupine beaters in the present invention rotate in opposite directions, so that the cotton can be subjected to forces from two opposite directions in the cotton opening box, thereby making the cotton more evenly and thoroughly opened; further, a rotating joint is provided at one end of the pressure cylinder connected to the air pipe, which can ensure that the connection between the air pipe and the pressure cylinder is stable during the rotation of the porcupine roller, thereby ensuring the normal supply of high-pressure gas.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0030] See also Figure 1 and Figure 2 This is a structural diagram of a cotton opener for textile production in this embodiment. The cotton opener in this embodiment includes a cotton opening box 100. Porcupine beaters are symmetrically arranged in the cotton opening box 100, and the rotation directions of the porcupine beaters are opposite. A feed hopper 101 is provided on the upper surface of the cotton opening box 100, and the bottom of the feed hopper 101 is located directly above a pair of porcupine beaters. In this embodiment, the rotation directions of the porcupine beaters are opposite, so that the cotton in the cotton opening box is subjected to forces from two opposite directions, thereby making the cotton opening more uniform and thorough. Cotton is fed through the feed hopper 101 and falls between a pair of porcupine beaters for easy opening.

[0031] See also Figure 4 The porcupine beater in this embodiment includes a porcupine roller 200, a pressure cylinder 203 is inserted into the porcupine roller 200, the pressure cylinder 203 is concentric with the porcupine roller 200, and air holes are evenly opened on the surface of the pressure cylinder 203. A fixed tube 205 is connected to the surface of the air holes. A movable tube 206 is slidably connected to the outside of the fixed tube 205, and a beater 2071 is installed at the end of the movable tube 206. One end of the pressure cylinder 203 is closed, and the other end of the pressure cylinder 203 is connected to an air pipe 2042. The air pipe 2042 is externally connected to a gas compressor. In this embodiment, the gas compressor inputs high-pressure gas into the pressure cylinder 203 through the air pipe 2042, and the gas flows into the fixed tube 205 in the pressure cylinder 203, so that the movable tube 206 is pushed outward on the fixed tube 205 by the high-pressure gas. When the movable tube 206 moves outward, the beater 2071 is pushed out, so that the device can loosen the cotton through the beater 2071; In the first step, in order to realize the extension and retraction of the beater 2071, in this embodiment, through holes 201 are evenly opened on the surface of the porcupine roller 200, and the through holes 201 correspond to the positions of the air holes. High-pressure gas is injected into the pressure cylinder 203 through the air pipe 2042, and the movable tube 206 is pushed to move toward the surface of the porcupine roller 200 by the gas. When the movable tube 206 moves, the beater 2071 is pushed out from the through hole 201, so that the beater 2071 protrudes from the surface of the porcupine roller 200. Further, the air in the pressure cylinder 203 can be evacuated by a gas compressor, so that the movable tube 206 moves inward under the air pressure difference, so that the beater 2071 is pulled into the porcupine roller 200 through the movable tube 206. In this embodiment, since the beater 2071 can shrink inside the porcupine roller 200, the cotton wrapped around the beater 2071 is easier to withdraw from between the two beaters, thereby reducing the cotton residue on the beater 2071.

[0032] See also Figure 5 and Figure 6In this embodiment, a flange 2051 is provided outwardly at the upper end of the fixed tube 205, and the diameter of the flange 2051 is equal to the inner diameter of the movable tube 206. The end of the movable tube 206 is integrally connected with a tube support 2062, and the inner side of the tube support 2062 contacts the outer surface of the fixed tube 205. In this embodiment, the flange 2051 at the upper end of the fixed tube 205 and the tube support 2062 at the end of the movable tube 206 are designed to cooperate. When the movable tube 206 is pushed by the high-pressure gas, the tube support 2062 and the flange 2051 can maintain a seal, ensuring that the high-pressure gas pushes the movable tube 206. 06 will not leak, thereby ensuring that the gas can effectively push the movable tube 206 outward, so that the beater 2071 can protrude from the surface of the porcupine roller 200 as expected, ensuring the normal function of the equipment. Further, when the inner surface of the tube support 2062 contacts the outer surface of the flange 2051, the movement of the movable tube 206 is restricted, and the extension distance of the movable tube 206 can be accurately controlled to avoid problems such as excessive extension of the movable tube 206 causing equipment failure or excessive protrusion of the beater 2071 affecting the cotton opening effect, thereby ensuring the stability and reliability of the equipment operation.

[0033] Continue reading Figure 5 and Figure 6In this embodiment, a sealing sheet 2061 is provided in the movable tube 206 away from the tube support 2062. The interior of the movable tube 206 is divided into two cavities, large and small, by the sealing sheet 2061. The fixed tube 205 is inserted into the large cavity. The inner wall of the small cavity in the movable tube 206 is provided with a thread to form a threaded hole 2063. The beater 2071 is placed in the threaded hole 2063. The above structure makes the connection of the beater 2071 in the movable tube 206 more stable. During the operation of the equipment, even if the beater 2071 is subjected to vibration or other external forces, it is not easy to loosen or shift, thereby ensuring that the beater 2071 can accurately perform the cotton opening work; further, the tail of the beater 2071 is connected to a connecting block 207, the upper surface of the connecting block 207 is grooved in the middle, the tail of the beater 2071 is opened, and a torsion spring is provided in the hole. The beater 2071 is rotatably connected to the groove of the connecting block 207 through the torsion spring. In this embodiment, the connecting block 207 is connected by threads, so that The beaters 2071 can be replaced to avoid the deterioration of the cotton opening effect caused by the wear of the beaters 2071, and a certain degree of adaptive adjustment can be made according to the state of the cotton during the cotton opening process. When encountering a larger piece of cotton, the beaters 2071 can be pushed and pulled by the movable tube 206, and the beaters 2071 can be slightly opened or adjusted in angle under the action of the torsion spring to better open the cotton; a pair of beaters 2071 are arranged in a scissor shape in the groove of the connecting block 207, and the upper ends of the outer surfaces of the beaters 2071 are inclined surfaces, and the width of the inclined surfaces gradually decreases from top to bottom, and the length of the inclined surfaces is half the length of the beaters 2071. A blade is arranged on one side opposite to the beaters 2071. The upper ends of the outer surfaces of the beaters 2071 of this embodiment are inclined surfaces, and the width of the inclined surfaces gradually decreases from top to bottom, which is conducive to the retraction of the beaters 2071 into the porcupine roller 200, and the beaters 2071 arranged in a scissor shape are squeezed through the through holes 201 so that it is easier to close the cotton that is entangled and broken by the blades.

[0034] See also Figure 7 and Figure 8 In the present invention, when the movable tube 206 is retracted by suction to pull the beater 2071 into the porcupine drum 200, the beater 2071 arranged in a scissor shape is closed. This design can directly cut the cotton wrapped around the beater 2071. Compared with the traditional method, manual cleaning is not required, which greatly improves the cleaning efficiency. Furthermore, since the beater 2071 can be retracted inside the porcupine drum 200, the cotton wrapped around the beater 2071 can be more easily withdrawn from between the two beaters 2071, reducing the cotton residue on the beater 2071, further improving the thoroughness of cleaning. The upper end of the outer surface of the beater 2071 is an inclined surface, and the width of the inclined surface gradually decreases from top to bottom, which is conducive to the retraction of the beater 2071 into the porcupine drum 200. The inclined surface is squeezed by the through hole 201, so that the beater 2071 arranged in a scissor shape is easier to close and the wound cotton is broken by the blade. The above design does not need to open an excessively long groove, thereby avoiding cotton wool being blocked in the groove and causing the cleaning mechanism to be paralyzed.

[0035] See also Figure 2 and Figure 3 In this embodiment, a rotary joint 2031 is provided at one end of the pressure cylinder 203 connected to the air pipe 2042. The air pipe 2042 is connected to the end of the pressure cylinder 203 through the rotary joint 2031. This can ensure that the connection between the air pipe 2042 and the pressure cylinder 203 is stable during the rotation of the porcupine roller 200, thereby ensuring the normal supply of high-pressure gas. Since the rotary joint 2031 and the air pipe 2042 have a certain weight, in order to maintain stability during rotation, a counterweight block 2043 for balancing the weight is provided inside the other end of the pressure cylinder 203 in this embodiment to ensure that the pressure The two ends of the drum 203 are balanced; further, bearing seats 202 are provided at both ends of the porcupine roller 200, and the porcupine roller 200 is rotatably connected to the cotton opening box 100 through the bearing seats 202. A first motor 102 is installed on the outside of the cotton opening box 100, and the output end passes through the cotton opening box 100 and is connected to one end of the porcupine roller 200. In this embodiment, the porcupine roller 200 is driven to rotate by the first motor 102, and the rotation direction of the porcupine roller 200 is opposite, so that the cotton can be subjected to forces from two opposite directions in the cotton opening box 100, thereby making the cotton better opened.

[0036] See also Figure 3 A conveying box 103 is installed at the bottom of the cotton opening box 100, and a crawler conveyor 104 is built in the conveying box 103. A second motor 1041 is installed on the outer side of the conveying box 103. The driving end of the second motor 1041 is connected to one end of the crawler conveyor 104. In this embodiment, the loosened cotton falls into the crawler conveyor 104 in the conveying box 103, and the crawler conveyor 104 is driven by the second motor 1041 to throw out the loosened cotton.
