Description

Technical Field

[0001] The present application relates to the field of raw sliver bundling, and in particular to a raw sliver uniform bundling device. Background Art

[0002] Raw sliver refers to a continuous strip-shaped semi-finished product made by opening and combing the fiber material in the previous process. Raw sliver in the prior art is mostly made by roller carding machine.

[0003] In the prior art, a buncher generally refers to a device that gathers fibers into bundles in a roller carding machine. The fibers first pass through the carding rollers to form a cotton web, and the cotton web passes through the buncher to form a raw sliver. The cotton web between the carding rollers and the buncher is formed into a triangle that is narrow in the front and wide in the back.

[0004] With respect to the above-mentioned related technologies, in the actual production process of raw sliver, the cotton web used to constitute the raw sliver may come into contact with the roller carding machine due to various reasons, one of which is the influence of static electricity. The friction between the raw sliver and the roller causes static electricity to be generated, which in turn causes static electricity to adsorb the fibers constituting the raw sliver, causing a part of the fibers to come into contact with the roller carding machine. The contact between the cotton web and the roller carding machine will affect the quality of the produced raw sliver, and further affect the spinnability of the raw sliver. Summary of the invention

[0005] In order to reduce the contact between the cotton web and the roller carding machine, and thus improve the quality of the produced raw sliver, the present application provides a raw sliver uniform bundling device.

[0006] The present application provides a uniform sliver bundling device that adopts the following technical solution:

[0007] A device for uniformly bundling raw slivers comprises a machine base, a carding mechanism and a bundling mechanism, wherein the carding mechanism is used to card fibers into a cotton web, the bundling mechanism comprises a bundling assembly and a floating assembly, the bundling assembly is arranged on the machine base and is used to bundle the cotton web into raw slivers, the floating assembly comprises an air pump and a plurality of air blowing pipes, the air pump is fixedly arranged on the machine base, each of the air blowing pipes is fixedly arranged on the machine base and connected to the air pump, and the blowing area of ​​each of the air blowing pipes is a triangular area formed from wide to narrow during the bundling process of the cotton web between the carding mechanism and the bundling assembly.

[0008] By adopting the above technical scheme, when the bundling device is working, the combing mechanism combs the fibers into a cotton web and conveys it to the bundling assembly.

At this time, the air pump is working, and the air flow output by the air pump is blown out through each air pipe, so that the cotton web is kept floating by the air flow, so that the cotton web is not easily adsorbed by the static electricity of the roller combing machine, and the problem of the cotton web used to constitute the raw strips being in contact with the roller combing machine for various reasons during the actual production of the raw strips is improved, among which the reasons include the influence of static electricity. The friction between the raw strips and the rollers causes static electricity to be generated, which in turn causes static electricity to adsorb the cotton web constituting the raw strips, thereby causing a part of the cotton web to contact with the roller combing machine.

The bundling block is provided with a plurality of bundling teeth, and each of the bundling teeth is respectively abutted against the cotton net.

[0016] By adopting the above technical scheme, when the cotton web enters the bundling block through the bundling hole, the cotton web moves along the length direction of the bundling block, so that the cotton webs move closer to each other, so that the cotton webs are further bundled, so that the bundling block amplifies the bundling effect of the bundling hole, and at the same time, each bundling tooth abuts against the cotton web respectively, so that when the bundling block bundles the cotton web, the cotton web is combed by each bundling tooth respectively, so that the cotton web is combed more smoothly, thereby making the bundling effect of the cotton web better and making it more usable.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a device for uniformly bundling raw slivers. Figure 1 A sliver uniform bundling device comprises a machine base 1, a carding mechanism 2 and a bundling mechanism 3, wherein the carding mechanism 2 is arranged on the machine base 1, the bundling mechanism 3 is arranged on the machine base 1, and the bottom of the machine base 1 is rectangular.

[0034] Reference Figure 1The combing mechanism 2 includes a bristle roller 21, an upper pressure roller 22, a lower pressure roller 23 and two combing rollers 24. The bristle roller 21, the upper pressure roller 22, the lower pressure roller 23 and the two combing rollers 24 are sequentially arranged inside the machine base 1 along the length direction of the bottom of the machine base 1. The bristle roller 21 is rotatably arranged inside the machine base 1. The upper pressure roller 22 is rotatably arranged inside the machine base 1 and abuts and cooperates with one side of the bristle roller 21. The upper pressure roller 22 and the bristle roller 21 rotate in opposite directions. The lower pressure roller 23 is rotatably arranged on the machine base 1. The lower pressure roller 23 abuts and cooperates with the upper pressure roller 22 and rotates in the opposite direction to the upper pressure roller 22. Both combing rollers 24 are rotatably arranged on the machine base 1. The two combing rollers 24 abut and cooperate with each other. The upper pressure roller 22 transports the fiber to the abutment position of the two combing rollers 24.

[0035] When the combing mechanism 2 combs the cotton web, the brush roller 21 rotates to brush the cotton web, so that the cotton web fibers are preliminarily arranged, and then transported to the upper pressing roller 22. The upper pressing roller 22 rotates to transport the preliminarily arranged cotton web to the lower pressing roller 23. At the same time, the cotton web is rolled through the abutment between the upper pressing roller 22 and the lower pressing roller 23, so that the cotton web is more concentrated and easier to be bundled. Then the lower pressing roller 23 rolls the cotton web to the position where the two combing rollers 24 abut against each other, so that the fibers are preliminarily regularized by the combing of the two combing rollers 24 to form a cotton web, thereby facilitating the bundling of the bundling component 31, thereby making the bundling effect better.

[0036] Reference Figure 2 The combing mechanism 2 also includes two groups of brush cleaning assemblies 25, which correspond to the two combing rollers 24 respectively. The two groups of brush cleaning assemblies 25 each include a brush cleaning block 251, a brush cleaning head 252, two clamping rods 253 and two brush cleaning springs 254. The two brush cleaning blocks 251 are rotatably arranged inside the machine base 1 and are respectively located on the side of the two combing rollers 24 that are away from each other. A brush cleaning groove is opened on one side of the two brush cleaning blocks 251, and the two brush cleaning heads 252 are respectively penetrated and fixed in the two brush cleaning grooves, and the two brush cleaning heads 252 are respectively abutted and matched with the two combing rollers 24. Each clamping rod 253 is respectively fixedly arranged on the two brush cleaning blocks 251, and one end of each brush cleaning spring 254 is fixedly connected to the machine base 1, and the other end of each brush cleaning spring 254 is respectively fixedly connected to each clamping rod 253.

[0037] When the combing roller 24 rotates, the cleaning brush block 251 presses the cleaning brush head 252 to the outer peripheral surface of the combing roller 24, so that the cleaning brush head 252 brushes off the cotton net adhered to the outer peripheral surface of the combing roller 24 as the combing roller 24 rotates, so that the cotton net adhered to the outer peripheral surface of the combing roller 24 is not easy to affect the combing work of the combing roller 24, thereby making the combing effect of the combing roller 24 better. The setting of the cleaning brush spring 254 enables the cleaning brush spring 254 to provide thrust for the cleaning brush block 251, so that the cleaning brush block 251 pushes the cleaning brush head 252 close to the direction of the combing roller 24 until it abuts against the combing roller 24, so that the cleaning brush head 252 always keeps abutting against the combing roller 24, so that the cleaning effect of the cleaning brush head 252 is further improved.

[0038] Reference Figure 3 The bundling mechanism 3 includes a bundling assembly 31, which includes a bundling motor 311, a bundling moving wheel 312 and a bundling idler wheel 313. The bundling motor 311 is fixedly arranged on one side of the machine base 1, and the bundling moving wheel 312 is cylindrical. The bundling moving wheel 312 is coaxially fixed on the output shaft of the bundling motor 311. The bundling idler wheel 313 is cylindrical. The bundling idler wheel 313 is fixedly arranged on the shell of the bundling motor 311 and is located at the bottom of the bundling moving wheel 312. The bundling idler wheel 313 is abutted against the bundling moving wheel 312. An annular bundling groove is provided on the outer circumference of the bundling idler wheel 313, and the bundling groove is used to bundling the cotton web. A bundling hole is provided on one side of the bundling motor 311, and the bundling hole is opposite to the center position of the two combing rollers 24, so that when the cotton web is bundled, it is symmetrical along the middle position of the two combing rollers 24.

[0039] When the bundling assembly 31 is bundling the cotton web, the bundling motor 311 is driven, and the output shaft of the bundling motor 311 drives the bundling wheel 312 to rotate, and the bundling wheel 312 drives the cotton web to pass through the bundling hole for preliminary bundling, and then the initially bundled cotton web moves to the abutment and cooperation position between the bundling wheel 312 and the bundling idler wheel 313, so that the initially bundled cotton web is further bundled and squeezed through the abutment and cooperation between the bundling wheel 312 and the bundling idler wheel 313, so that the cotton web is bundled into raw strips, thereby completing the bundling of the cotton web, making the bundling of the cotton web simpler and more convenient.

[0040] Reference Figure 3 The clustering assembly 31 also includes a clustering block 314, which is in a truncated cone shape. The clustering block 314 is fixedly arranged on the side of the clustering hole close to the clustering impeller 312 and is coaxially arranged with the clustering hole. The diameter of the clustering block 314 gradually decreases from the side close to the clustering hole to the side close to the clustering impeller 312. The clustering block 314 is provided with a plurality of clustering teeth 315 on the side close to the clustering impeller 312. The clustering teeth 315 are evenly distributed circumferentially around the axis of the clustering block 314, and the clustering teeth 315 are respectively abutted against the cotton net.

[0041] When the cotton web enters the clustering block 314 through the clustering holes, the cotton web moves along the length direction of the clustering block 314, so that the cotton webs move closer to each other, so that the cotton webs are further clustered, so that the clustering block 314 amplifies the clustering effect of the clustering holes, and at the same time, each clustering tooth 315 is respectively in contact with the cotton web, so that when the clustering block 314 clusters the cotton web, the cotton web is combed by each clustering tooth 315, so that the cotton web is combed more smoothly.

[0042] Reference Figure 4 The bundling machine also includes a floating component 32, which includes an air pump 321, an adjusting air valve 322, and two air pipes 323. The air pump 321 is fixedly arranged inside the machine base 1, and the adjusting air valve 322 is fixedly arranged on the air pump 321. The air inlet of the adjusting air valve 322 is connected with the air pump 321. The two air pipes 323 are respectively fixedly arranged on both sides of the machine base 1 and located at both ends of the two combing rollers 24. The middle height of the air blowing of each air pipe 323 is higher than the abutment position of the two combing rollers 24. The two air pipes 323 are respectively connected with the two air outlets of the adjusting air valve 322. The blowing area of ​​each air pipe 323 is a triangular area formed from wide to narrow during the cotton web bundling process between the combing mechanism 2 and the bundling component 31.

[0043] When each blowing pipe 323 is blowing, the air flow rate on the side of the cotton net close to the machine base 1 is smaller than the air flow rate on the side of the cotton net away from the machine base 1, thereby causing a pressure difference on both sides of the cotton net away from the machine base 1. Therefore, when the blowing pipe 323 blows air, the cotton net moves in the direction away from the machine base 1, making it difficult for the cotton net to contact the machine base 1. At the same time, each blowing pipe 323 blows air on both sides of the cotton net, and the blown air flow pushes the cotton net to the middle position for bundling. The setting of the air valve 322 is adjusted so that the air flow rate blown out by each blowing pipe 323 has controllable performance, so that the air flow blown out by each blowing pipe 323 is more suitable for cotton nets of various materials and in various environments, so that the blowing effect of each blowing pipe 323 is better and the bundling effect of the cotton net is better.

[0044] The implementation principle of a uniform bundling device for raw slivers in an embodiment of the present application is as follows: when the bundling device is working, the combing mechanism 2 combs the fibers into a cotton web and conveys it to the bundling assembly 31. When the bundling assembly 31 is bundling the cotton web into raw slivers, the cotton web is formed into a triangle from the combing mechanism 2 to the bundling assembly 31 from wide to narrow. At this time, the air pump 321 is working, and the air flow output by the air pump 321 is blown out through each air pipe 323, so that the cotton web is kept floating by the air flow, so that the cotton web is not easily adsorbed by the static electricity of the roller combing machine, thereby improving the problem that in the actual production process of raw slivers, the cotton web used to constitute the raw sliver may contact the roller combing machine due to various reasons, among which the reasons include the influence of static electricity. The friction between the raw sliver and the roller causes static electricity to be generated, which in turn causes static electricity to adsorb the fibers constituting the raw sliver, thereby causing a part of the fibers to contact the roller combing machine. The contact of the cotton web with the roller combing machine will affect the quality of the raw sliver produced, and then affect the spinnability of the raw sliver.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
