Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile production technology especially relates to a even cotton mixing equipment for textile production. BACKGROUND

[0002] Textile refers to the process of spinning cotton, hemp, silk, wool and other fibers into yarn or thread, and then weaving these yarns or threads into cloth, silk, wool and other textiles. The uniform mixing of cotton is a key factor in ensuring the quality of subsequent spinning, weaving and other processes.

[0003] In the process of textile production, cotton mixing is a crucial link that directly affects the quality of subsequent spinning and weaving. However, the existing cotton mixing equipment for textile production, such as the equipment disclosed in the utility model with announcement number CN219430205U, still has many shortcomings in actual application. First of all, when mixing cotton, the equipment often ignores the opening operation of the cotton. Since cotton is prone to clumping during storage and transportation, cotton that has not been opened will not be evenly dispersed during mixing, resulting in poor cotton mixing effect and affecting the quality of the final product.

[0004] Secondly, the existing cotton mixing equipment often cannot effectively remove impurities from the cotton during the mixing process. These impurities may include dust, short fibers, cottonseed hulls, etc., which not only affect the uniformity of cotton mixing, but also may damage textile machinery, reduce production efficiency, and even affect the use performance and appearance quality of the final product.

[0005] In addition, the mixing efficiency and automation level of the existing equipment need to be improved. Traditional cotton mixing equipment relies on manual operation or simple mechanical structures, making it difficult to achieve synchronous operation and precise control of various components, resulting in low mixing efficiency and poor production stability. Therefore, we propose a uniform cotton mixing equipment for textile production to solve the above problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at solving the shortcomings that cotton is not opened and impurities are not removed during mixing in the prior art, resulting in poor cotton mixing effect and affecting the quality of cotton mixing, and proposes a uniform cotton mixing equipment for textile production.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A uniform cotton mixing equipment for textile production, comprising a cotton mixing box, a feed inlet for feeding cotton is formed on the top of the cotton mixing box, a discharge outlet for discharging is formed on one side of the cotton mixing box, fixed plates are arranged on the inner walls of both sides of the cotton mixing box, a conveying belt machine is arranged inside the cotton mixing box, and the equipment further comprises:

[0009] Two sets of preliminary mixing assemblies are arranged inside the cotton mixing box and horizontally, and each set of preliminary mixing assembly comprises a plurality of feed rollers and beaters for preliminary mixing of cotton;

[0010] A secondary mixing assembly is arranged inside the cotton mixing box and comprises a stirring rod, which is located below the two sets of preliminary mixing assemblies for further mixing of cotton;

[0011] An impurity collecting assembly is arranged on one side of the cotton mixing box and comprises a dust collecting box for collecting impurities in the cotton.

[0012] In a possible design, the preliminary mixing assembly comprises two feed rollers and beaters, both of which are rotatably connected to the inner walls of the two sides of the cotton mixing box, and both of which extend to the outside of the cotton mixing box. The outer wall of each feed roller is fixedly sleeved with a first driven gear, and the two first driven gears are in meshing connection. The outer wall of one of the feed rollers is fixedly sleeved with a second driven gear, the outer wall of the beater is fixedly sleeved with a first driving gear, and the second driven gear is in meshing connection with the first driving gear.

[0013] In a possible design, the secondary mixing assembly comprises a stirring rod rotatably connected to the inside of the cotton mixing box, one end of the stirring rod extending to the outside of the cotton mixing box, a first motor fixedly arranged on one side of the cotton mixing box, and the output end of the first motor fixedly connected with the stirring rod.

[0014] In a possible design, the outer wall of the stirring rod is fixedly sleeved with a first driving sprocket, the outer wall of the beater of each set of preliminary mixing assembly is fixedly sleeved with a first driven sprocket, and the first driving sprocket and the two first driven sprockets are in transmission connection with the same first chain.

[0015] In a possible design, two blow pipes are fixedly and penetratively connected in one of the fixed plates, the air inlets of the two blow pipes are fixedly connected with the same connecting pipe, a blower is fixedly connected on one side of the cotton mixing box, and the air outlet of the blower is fixedly connected with the connecting pipe.

[0016] In a possible design, the two blow pipes are both conical and internally provided with helical blades for generating rotating air flow by blowing in gas, so that the cotton moves more strongly and the cotton mixing effect is improved.

[0017] In a possible design, the impurity collecting assembly comprises a dust collecting box fixedly arranged on one side of the cotton mixing box, the dust collecting box is in communication with the inside of the cotton mixing box, the dust collecting box is provided with a separation net on the side close to the cotton mixing box, and the dust collecting box is fixedly provided with an air extractor on the side away from the cotton mixing box.

[0018] In a possible design, one side of the stirring rod is fixedly provided with a scraper made of soft rubber material, and the scraper is in contact with a separation net on one side of the dust collecting box. The separation net is arc-shaped, and the curvature of the bending is the same as the curvature of the running track of the scraper. When the stirring rod rotates, the scraper on the stirring rod is used to clean the separation net, so that the cotton is prevented from being adsorbed on the separation net due to the influence of the air extractor, and thus the impurities cannot be collected.

[0019] In a possible design, the inside of the cotton mixing box is rotationally connected with two cotton combing rollers. The two cotton combing rollers are horizontally arranged and located below the stirring rod. One end of each of the two cotton combing rollers extends to the outside of the cotton mixing box. The outer wall of each of the two cotton combing rollers is fixedly sleeved with a third driven gear. The two third driven gears are in mesh with each other. One side of the cotton mixing box is fixedly provided with a second motor. The output end of the second motor is fixedly connected with one of the transmission rollers of the conveying belt machine. The outer wall of each of the one of the transmission rollers of the conveying belt machine and the one of the cotton combing rollers is fixedly sleeved with a second driven sprocket. The two second driven sprockets are transmissionally connected with a second chain.

[0020] In the application, first, the cotton is put into the cotton mixing box through the feeding port, and then the first motor is started. The first motor drives the stirring rod to rotate, and at the same time, the first motor drives the first driven sprocket on the two beaters to rotate through the first driven sprocket on the stirring rod and the first chain. Thus, the two beaters rotate, and the first driven sprocket on each of the two beaters drives the corresponding second driven sprocket to rotate. The rotation of the two second driven sprockets drives the two feed rollers to rotate. The two rotating feed rollers drive the other two feed rollers to rotate through the first driven sprocket, so that the power of each component is synchronously transmitted.

[0021] The relative rotation of the two rollers conveys the cotton to the direction of the beater. The beater further disperses and mixes the cotton while rotating. The preliminarily mixed cotton falls into the middle part of the cotton mixing box and is subjected to secondary mixing by the stirring rod.

[0022] During the secondary mixing process, the air blower continuously works. The air blower blows the external air into the cotton mixing box through the connecting pipe. The spiral blades arranged in the blowing pipe can make the blown gas rotate and accelerate the circulation of the gas, so that the cotton can move more violently, the mixing process and efficiency are accelerated, and the impurities in the cotton can be blown up.

[0023] The impurities enter the dust collecting box along with the airflow, are extracted by the air extractor after being filtered by the separation net, and are collected. In addition, the scraper on one side of the stirring rod continuously cleans the separation net during the rotation process, so that the cotton is prevented from being adsorbed to cause poor collection of the impurities.

[0024] After being mixed fully and impurities being separated, the cotton is finally output from the discharge port through the conveying belt machine and enters the next process, and meanwhile, the two cotton cards are rotated under the driving of the second motor and the second chain to card the cotton about to be output, so that the evenness and quality of the cotton are further improved.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0038] Embodiment 1

[0039] Reference Figures 1-5 A cotton mixing equipment, comprising a cotton mixing box 1, the top of the cotton mixing box 1 is provided with a feeding port for feeding the cotton raw materials to be mixed. A mixing cavity is formed inside the cotton mixing box 1 for uniform mixing of the cotton. The cotton mixing box 1 is provided with a discharge port on one side for outputting the uniformly mixed cotton. Fixed plates 4 are installed on both sides of the inside of the cotton mixing box 1 for supporting and fixing the components inside the equipment. In addition, a conveying belt machine 8 is also installed inside the cotton mixing box 1. The conveying belt machine 8, also known as a belt conveyor, a belt conveyor or a rubber belt conveyor, is a commonly used material conveying equipment. According to the friction transmission principle, the motor transmits power to the speed reducer, and the speed reducer drives the driving roller through the chain wheel and chain to make the belt run, thereby realizing the continuous operation of the material. The mixed cotton falls on the belt, and the cotton is conveyed to the next process through the belt, which is used for conveying the cotton during and after mixing.

[0040] Two groups of preliminary mixing components are arranged inside the cotton mixing box 1 and are arranged horizontally. The components include two cotton feeding rollers 2 and a beater 3. The two cotton feeding rollers 2 and the beater 3 are rotatably connected with the inner walls of both sides of the cotton mixing box 1, and one end thereof extends to the outside of the cotton mixing box 1 for easy driving.

[0041] Specifically, the feed rollers 2 and beaters 3 are generally rotatably connected to the shell of the rear side wall of the mixing box 1 through bearings, and are located outside the mixing box 1 for connecting driving devices (such as motors, reducers, etc.), so as to control the rotating speed and direction thereof. The two feed rollers 2 are horizontally arranged, and a gap is left between the two adjacent feed rollers 2, so as to control the thickness and uniformity of the cotton layer, and ensure that the cotton fibers enter the mixing area in a stable manner. The beaters 3 are located between or slightly behind the two feed rollers 2, and generate strong mechanical forces through high-speed rotation to strike, tear and mix the cotton fibers passing between the two feed rollers 2, so as to realize the opening and preliminary mixing of the fibers.

[0042] The outer walls of the two feed rollers 2 are respectively fixedly sleeved with first driven gears 201 which are meshed with each other, so as to realize synchronous reverse rotation, thereby effectively grabbing and conveying the cotton. One of the feed rollers 2 is additionally fixedly sleeved with a second driven gear 202, which is meshed with a first driving gear 301 on the outer wall of the beater 3, so that the beater 3 can rotate with the feed roller 2, and further scatter and preliminarily mix the cotton.

[0043] Specifically, when the first driving gear 301 rotates clockwise, the second driven gear 202 and the first driven gear 201 will rotate counterclockwise. The counterclockwise rotation of the first driven gear 201 will drive the first driven gear 201 of the adjacent feed roller 2 to rotate clockwise. At this time, the left feed roller 2 of the two adjacent feed rollers 2 rotates clockwise, and the right feed roller 2 rotates counterclockwise. The two feed rollers 2 push the cotton layer to the gap, and the beater 3 below the gap rotates clockwise to preliminarily strike, tear and mix the cotton layer.

[0044] The secondary mixing assembly is arranged below the two preliminary mixing assemblies, and mainly comprises a stirring rod 6. The stirring rod 6 is rotatably connected to the inside of the mixing box 1, and one end thereof extends to the outside of the mixing box 1 and is fixedly connected with the output end of the first motor 12, and is driven to rotate by the first motor 12. The outer wall of the stirring rod 6 is fixedly sleeved with a first driving sprocket 601, which is drivingly connected with the first driven sprocket 302 on the outer wall of the beater 3 in the two preliminary mixing assemblies through a first chain 14, so as to realize power transmission and synchronous movement, and further enhance the mixing effect.

[0045] Specifically, the stirring rod 6 is rotatably connected to the shell of the rear side wall of the mixing box 1 through a bearing. When the output end of the first motor 12 rotates, the stirring rod 6 rotates synchronously, and the first driving sprocket 601 rotates synchronously, so as to drive the two first driving gears 301 to rotate through the first chain 14. Therefore, the two beaters 3 rotate synchronously, and when the two first driving gears 301 rotate, the two feed rollers 2 also rotate synchronously, so as to continuously perform the preliminary mixing and secondary mixing actions.

[0046] Two conical blowing pipes 5 are fixedly connected in one of the fixed plates 4, and each blowing pipe is internally provided with a spiral blade to generate a rotating air flow. The air inlet of the blowing pipe 5 is connected with the air outlet of the blower 16 through a connecting pipe 17, and the blower 16 sends air into the blowing pipe 5 when working to form a rotating air flow, so that the cotton moves more violently in the mixing box 1, thereby improving the mixing uniformity.

[0047] Specifically, the blower is a device for imparting energy to gas to increase its pressure, increase its speed and send it out. According to the working principle and structure form, the blower can be divided into various types, such as Roots blower, blast furnace blower, centrifugal blower, etc. The centrifugal blower used in the present application sucks and accelerates air through a high-speed impeller to form a certain air pressure and flow rate, and then guides the air to the desired position through a flow guide.

[0048] The gas blown by the blower 16 enters the blowing pipe 5 through the connecting pipe 17, and finally the rotating air flow is sprayed out from the lower outlet of the blowing pipe 5. The sprayed rotating air enters the secondary mixing stirring cavity to provide mixing effect on the secondary mixed cotton fibers.

[0049] The impurity collecting assembly includes a dust collecting box 9 fixedly arranged on one side of the mixing box 1 and connected with the inside of the mixing box 1. The dust collecting box 9 is provided with a separation net on the side close to the mixing box 1 for separating cotton and impurities. The dust collecting box 9 is provided with an air extractor 10 on the side away from the mixing box 1 for extracting and collecting the impurities generated in the mixing process.

[0050] Specifically, the air extractor 10, also known as a side flow blower, a centrifugal blower or a small blower, is a general air source for blowing or sucking, which is widely used in various industrial, agricultural and public facilities fields. When the motor drives the impeller to rotate, air enters from the two air inlets, rotates with the impeller and is thrown to the edge from the center of the impeller under the action of centrifugal force, and then flows into the volute at a high speed and is guided by the volute to the exhaust port. In this process, the fan forms a certain vacuum degree (negative pressure) at the air inlet, and the air inlet of the air extractor 10 is arranged in the dust collecting box 9, so that air can be sucked in, and the impurities generated in the mixing process enter the dust collecting box 9 by forming negative pressure.

[0051] The present application can be used in the field of textile production, and can also be used in other fields applicable to the present application.

[0052] Example 2

[0053] Reference Figures 1-3The improved example one is a uniform cotton mixing equipment for textile production, which is applied to the technical field of textile production. The stirring rod 6 is fixedly provided with a scraper 11 made of soft rubber material on one side, and the scraper 11 is in close contact with the isolation screen on one side of the dust collection box 9. The bending radius of the scraper 11 matches the track radius of the stirring rod 6 during rotation, so that the scraper 11 can effectively clean the attachments on the isolation screen during the rotation of the stirring rod 6, preventing the cotton from being adsorbed on the isolation screen due to the suction of the air extractor 10, and affecting the normal collection of impurities.

[0054] Specifically, the dust collection box 9 generates negative pressure through the air extractor 10, part of the cotton is adsorbed on the isolation screen, and the smaller impurities enter the dust collection box 9 for collection through the isolation screen. During the rotation of the stirring rod 6, the scraper 11 is scraped from the isolation screen, thereby scraping the attachments on the isolation screen.

[0055] The mixing box 1 is also provided with two cotton combing rollers 7, which are horizontally arranged and located below the stirring rod 6. The two cotton combing rollers 7 are synchronously and reversely rotated by being meshed with each other through the third driven gear 701, further combing and mixing the cotton. The output end of the second motor 13 is fixedly connected with a transmission roller of the conveying belt conveyor 8, and the transmission roller of the conveying belt conveyor 8 and the outer wall of one cotton combing roller 7 are both fixedly sleeved with the second driven sprocket 702, which are transmission connected through the second chain 15, thereby realizing the linkage between the conveying belt conveyor 8 and the cotton combing roller 7 and improving the overall operation efficiency of the equipment.

[0056] Specifically, the output end of the second motor 13 rotates clockwise after being powered on, drives the transmission roller on the left side of the conveying belt conveyor 8 to rotate clockwise, and synchronously drives the second driven sprocket 702 to rotate clockwise through the second chain 15. The clockwise rotation of the second driven sprocket 702 drives the coaxial third driven gear 701 to rotate clockwise, and the third driven gear 701 drives the third driven gear 701 of the other cotton combing roller 7 on the right side to rotate counterclockwise, so that the left cotton combing roller 7 rotates clockwise and the right cotton combing roller 7 rotates counterclockwise when the left cotton combing roller 7 rotates clockwise, so that the cotton layer mixed once and twice is conveyed downward from the gap between the two cotton combing rollers 7 and falls on the conveying belt of the conveying belt conveyor 8. The transmission rollers at both ends of the conveying belt conveyor 8 rotate clockwise, so that the conveying belt moves towards the discharge port, thereby completing the discharging action.

[0057] However, as known to those skilled in the art, the working principle and wiring method of the first motor 12 and the second motor 13 are common, which belong to conventional means or common knowledge, and will not be described here. Those skilled in the art can make any selection according to their needs or convenience.

[0058] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
