Description

Technical Field

[0001] The invention belongs to the technical field of textile machinery, in particular to a cotton net cleaner of a carding machine. Background Art

[0002] As a key equipment in the textile industry, the core function of the carding machine is to carry out fine processing of the preliminary processed cotton fiber raw materials. These raw materials may come from the cotton rolls in the previous process, or they may be the oily cotton layer directly supplied by the cotton box. The carding machine achieves the thorough separation, careful combing and deep purification of the cotton fibers through a series of complex mechanical operations.

[0003] However, in the current cotton web cleaner technology, a problem that cannot be ignored is the limitations of the traditional clamping mechanism. Due to the different requirements of different spinning raw materials and processes, the styles and sizes of the cylinders (i.e., combing elements) are also different, but the traditional clamping mechanisms mostly adopt a fixed or limited adjustment method, which is difficult to flexibly cope with cylinders of different specifications and sizes. This results in that every time the production line needs to replace the cylinder to adapt to new spinning requirements, it has to take measures such as replacing the entire set of clamping devices or making complex adjustments. These extra steps not only increase production costs and downtime, but also reduce production efficiency and ease of operation.

[0004] What is more serious is that this cumbersome and time-consuming clamping and releasing process has a significant impact on the overall operating efficiency of the carding machine. Each replacement or adjustment of the cylinder will extend the production cycle, thereby reducing the overall production output. At the same time, due to the lack of the ability of traditional mechanisms to quickly adapt to changes in production lines, the application scope of the carding machine is also greatly limited. Therefore, it needs to be improved and optimized. Summary of the invention

[0005] In order to solve the problems of limited adjustment and low efficiency mentioned in the above background technology, the present invention provides a cotton web cleaner for a carding machine.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cotton net cleaner of a cotton carding machine, comprising two mounting blocks, a mounting mechanism is respectively provided on the side where the two mounting blocks are close to each other, the mounting mechanism comprises a slide groove opened on the front side of the mounting block, a screw rod is threadedly installed on the inner wall at the bottom of the slide groove, the screw rod passes through the mounting block, a rotating button and a gear are fixedly sleeved on the outer wall of the screw rod, two racks are slidably installed in the slide groove, both of the two racks are meshed with the gear, connecting blocks are respectively fixedly installed on the outer walls of the two racks, and clamping blocks are respectively fixedly installed on the side where the two connecting blocks are close to each other.

[0007] Preferably, hollow tube one and hollow tube two are fixedly installed on the sides of the two mounting blocks close to each other, and the sides of the two mounting blocks close to each other are elastically connected by a reset spring, and the reset spring is located at the center of the wall of hollow tube one and hollow tube two, and mounting sleeves are fixedly provided on the outer walls of hollow tube one and hollow tube two, and a cotton mesh cleaner is arranged under the two mounting sleeves, and the cotton mesh cleaner is fixedly connected to the two mounting sleeves by a plurality of bolt and nut fixings.

[0008] Preferably, two arc blocks are respectively arranged in the middle of the two clamping blocks, and the two arc blocks are elastically connected to the clamping blocks adjacent to each other through a plurality of spring damping rod assemblies.

[0009] Preferably, the outer walls of the two arc-shaped blocks are respectively slidably connected to the inner walls of the clamping blocks adjacent to each other, and the arc-shaped blocks maintain the same arc shape as the clamping blocks, but are proportionally reduced in size.

[0010] Preferably, a limiting disc is fixedly mounted on one end of the screw rod away from the gear, and the diameter of the limiting disc is greater than the diameter of the cross section of the screw rod.

[0011] Preferably, a fixing auxiliary block is threadedly sleeved on the outer wall of the screw rod, two concave limiting grooves are provided on the side of the fixing auxiliary block close to the gear, and an anti-collision block is fixedly installed on the outer wall of the fixing auxiliary block away from the gear.

[0012] Preferably, a T-shaped protrusion and a convex limiting block are fixedly mounted on the outer walls of the two racks respectively, the two T-shaped protrusions are slidably connected to the slide grooves, and the two convex limiting blocks are slidably connected to the corresponding concave limiting grooves respectively.

[0013] Preferably, two limiting grooves are fixedly installed on the outer wall of the hollow tube 1, and the two limiting grooves completely overlap in the vertical direction.

[0014] Preferably, the inner wall of the second hollow tube is provided with two limiting convex strips, and the two limiting convex strips are matched with the corresponding limiting concave strip grooves and are slidably connected with the corresponding limiting concave strip grooves.

[0015] Preferably, a cylinder is arranged between the two mounting blocks, and the four arc blocks are all in contact with the axis of the cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention drives the screw to rotate by rotating the rotary knob. The rotation of the screw rod will drive the gear to rotate synchronously, and then drive the two racks to make relative or opposite linear motion in the slide groove. Since the clamping block is connected to the rack through the connecting block, the clamping block will also move with the movement of the rack, thereby realizing flexible clamping and release of the cylinder. Compared with the traditional device, the position of the clamping block is adjusted by rotating the rotary knob, so that the device can adapt to cylinders of different specifications. The flexible fixing method avoids the adaptability problem caused by the single fixing method in the traditional device. The user only needs to simply rotate the rotary knob to complete the adjustment of the clamping block. No complicated operating steps or tools are required, which reduces the operating difficulty and labor intensity and improves work efficiency. Since the clamping block can quickly and accurately clamp or release the cylinder, the time required for replacing or adjusting components is reduced, which helps to improve the overall production efficiency of the carding machine.

[0018] The present invention fixes and installs hollow tube one and hollow tube two respectively on one side of two mounting blocks close to each other. This hollow tube design not only reduces the overall weight, but also cleverly hides the internal components, making the structure more compact and beautiful. A return spring is hidden in the center of the wall of hollow tube one and hollow tube two. The return spring provides elastic support for the relative movement between the mounting blocks, allowing flexible adjustment according to the length of the cylinder. When the hollow tube is pulled, the return spring provides a certain resistance to ensure that it can remain stable after being adjusted to the appropriate position. The cotton net cleaner and the two mounting sleeves are firmly fixedly connected by a plurality of bolt and nut fixings. This connection method is simple and reliable, which can not only ensure the stability of the cotton net cleaner during high-speed operation, but also facilitate disassembly and maintenance when needed. Compared with traditional devices, through the design of the return spring and the hollow tube, the size of the cotton net cleaner can be flexibly selected according to the requirements of different cylinder lengths, thereby improving the adaptability and flexibility of the equipment.

[0030] 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.

[0031] like Figures 1 to 10 As shown, the present invention provides a cotton web cleaner for a cotton carding machine, comprising two mounting blocks 1, wherein mounting mechanisms are respectively arranged on the sides of the two mounting blocks 1 close to each other, and the mounting mechanisms include a slide groove 101 opened on the front side of the mounting block 1, a screw rod 2 is threadedly installed on the bottom inner wall of the slide groove 101, the screw rod 2 passes through the mounting block 1, and a rotating button 3 and a gear 4 are fixedly sleeved on the outer wall of the screw rod 2, two racks 5 are slidably installed in the slide groove 101, and the two racks 5 are meshed with the gear 4, and connecting blocks 7 are respectively fixedly installed on the outer walls of the two racks 5, and clamping blocks 8 are respectively fixedly installed on the sides of the two connecting blocks 7 close to each other.

[0032] The screw rod 2 is driven to rotate by rotating the rotary knob 3, and the rotation of the screw rod 2 will drive the gear 4 to rotate synchronously, thereby driving the two racks 5 to make relative or opposite linear motion in the slide groove 101. Since the clamping block 8 is connected to the rack 5 through the connecting block 7, the clamping block 8 will also move with the movement of the rack 5, thereby realizing flexible clamping and release of the cylinder 17. Compared with the traditional device, the position of the clamping block 8 is adjusted by rotating the rotary knob 3, so that the device can adapt to cylinders 17 of different specifications. The flexible fixing method avoids the adaptability problem caused by the single fixing method in the traditional device. The user only needs to simply rotate the rotary knob 3 to complete the adjustment of the clamping block 8. No complicated operating steps or tools are required, which reduces the operating difficulty and labor intensity and improves work efficiency. Since the clamping block 8 can quickly and accurately clamp or release the cylinder 17, the time required for replacing or adjusting parts is reduced, which helps to improve the overall production efficiency of the carding machine.

[0033] like Figures 8 to 10 As shown, a hollow tube 10 and a hollow tube 2 11 are fixedly installed on one side of the two mounting blocks 1 close to each other, and the two mounting blocks 1 are elastically connected on one side of the two mounting blocks 1 close to each other through a reset spring 12, and the reset spring 12 is located at the center of the wall of the hollow tube 10 and the hollow tube 2 11, and mounting sleeves 15 are fixedly sleeved on the outer walls of the hollow tube 10 and the hollow tube 2 11, and a cotton mesh cleaner 16 is arranged under the two mounting sleeves 15, and the cotton mesh cleaner 16 is fixedly connected to the two mounting sleeves 15 by a plurality of bolt and nut fixings 18.

[0034] Hollow tube 10 and hollow tube 2 11 are fixedly installed on the side where two mounting blocks 1 are close to each other. This hollow tube design not only reduces the overall weight, but also cleverly hides the internal components, making the structure more compact and beautiful. The return spring 12 is hidden in the center of the wall of hollow tube 10 and hollow tube 2 11. The return spring provides elastic support for the relative movement between the mounting blocks 1, allowing flexible adjustment according to the length of the cylinder 17. When the hollow tube is pulled, the return spring will provide a certain resistance to ensure that it can remain stable after being adjusted to the appropriate position. The cotton mesh cleaner 16 and the two mounting sleeves 15 are firmly fixedly connected by a number of bolt and nut fixings 18. This connection method is simple and reliable, which can not only ensure the stability of the cotton mesh cleaner during high-speed operation, but also facilitate disassembly and maintenance when necessary. Compared with traditional devices, through the design of the return spring 12 and the hollow tube, the size of the cotton mesh cleaner 16 can be flexibly selected according to the requirements of different cylinder lengths, thereby improving the adaptability and flexibility of the equipment.

[0035] like Figure 6As shown, two arc blocks 801 are respectively arranged in the middle of the two clamping blocks 8, and the two arc blocks 801 are elastically connected to the clamping blocks 8 close to each other through a plurality of spring damping rod assemblies 9.

[0036] The elastic connection through the spring damping rod assembly 9 allows the arc block 801 to be fine-tuned as needed, thereby achieving flexible adaptation and stable clamping of different specifications.

[0037] like Figure 6 As shown, the outer walls of the two arc blocks 801 are respectively slidably connected to the inner walls of the clamping blocks 8 close to each other, and the arc block 801 maintains the same arc shape as the clamping block 8, but is proportionally reduced in size.

[0038] The arc block 801 has exactly the same arc shape as the clamping block 8 and is proportionally reduced, and the sliding connection can achieve highly precise adaptation, ensuring the smoothness and stability of the arc block 801 sliding on the inner wall of the clamping block 8, reducing wear and noise caused by friction.

[0039] like Figure 5 As shown, a limiting disc 201 is fixedly mounted on one end of the screw rod 2 away from the gear 4 , and the diameter of the limiting disc 201 is greater than the diameter of the cross section of the screw rod 2 .

[0040] The main function of the limiting disc 201 is to prevent the screw rod 2 from accidentally falling off from the installation position during operation. Since the diameter of the limiting disc 201 is larger than the diameter of the screw rod 2, it can form an effective barrier at one end of the screw rod 2 to ensure that the screw rod 2 is firmly maintained in the predetermined position and is not easy to loosen or fall off even when running at high speed or being impacted by external force.

[0041] like Figures 3 to 7 As shown, a threaded sleeve is provided on the outer wall of the screw rod 2 with a fixing auxiliary block 6 , and two concave limiting grooves 601 are provided on the side of the fixing auxiliary block 6 close to the gear 4 , and an anti-collision block 602 is fixedly installed on the outer wall of the fixing auxiliary block 6 away from the gear 4 .

[0042] The screw rod 2 is used as a rotating transmission component, and a fixed auxiliary block 6 is arranged on its outer wall through a threaded sleeve, so that the fixed auxiliary block 6 can be firmly fixed on the screw rod 2 and is not easy to loosen or move. Through the precise fit between the screw rod 2 and the thread, the position of the fixed auxiliary block 6 can be accurately adjusted by rotating the screw rod 2, so that the system can adapt to different needs, realize precise positioning or adjustment, and improve the flexibility and adaptability of the system.

[0043] like Figures 3 to 5As shown, T-shaped protrusions 501 and convex limiting blocks 502 are fixedly mounted on the outer walls of the two racks 5, respectively. The two T-shaped protrusions 501 are slidably connected to the slide groove 101, and the two convex limiting blocks 502 are slidably connected to the corresponding concave limiting grooves 601.

[0044] The sliding connection between the T-shaped protrusion 501 and the slide groove 101 provides precise positioning and stable guidance for the horizontal movement of the rack 5, ensuring the stability and accuracy of the rack 5 during movement and avoiding a decrease in cleaning effect or damage to the equipment due to position offset or shaking.

[0045] like Figures 8 to 10 As shown, two limiting grooves 13 are fixedly installed on the outer wall of the hollow tube 10, and the two limiting grooves 13 completely overlap in the vertical direction.

[0046] Through two vertically overlapping limiting grooves 13, a more stable support structure is provided for the hollow tube 10 and the components connected thereto, thereby greatly enhancing the stability and rigidity of the entire structure, so that the system can maintain precise positioning and stable support even when subjected to large external forces or vibrations, reducing the risk of performance degradation or failure caused by loose or offset components.

[0047] like Figures 8 to 10 As shown, the inner wall of the hollow tube 11 is provided with two limiting convex strips 14 , and the two limiting convex strips 14 are matched with the corresponding limiting concave strip grooves 13 and are slidably connected with the corresponding limiting concave strip grooves 13 .

[0048] Through the sliding connection mechanism of the limiting convex strip 14 and the limiting concave strip groove 13, additional support and guiding effects are provided for the hollow tube 11 and the components connected thereto, effectively preventing the components from shifting or loosening when running at high speed or under the action of external forces, thereby enhancing the structural stability and reliability of the entire cleaner.

[0049] like Figure 1 As shown, a cylinder 17 is arranged between the two mounting blocks 1 , and the four arc blocks 801 are all in contact with the axis of the cylinder 17 .

[0050] The four arc blocks 801 are in direct contact with the axis of the cylinder 17. This close-fitting design ensures that any attached impurities or short fibers can be more effectively stripped and removed when the cotton web passes through the cylinder 17. The design of the arc block 801 also optimizes the contact area and angle, further improving the cleaning efficiency and ensuring the purity of the cotton web and the quality of subsequent processing.

[0051] The working principle and use process of the present invention:

[0052] The operator first pulls apart the hollow tube 2 11 and the hollow tube 1 10. Through the elastic action of the reset spring 12, the distance between the two hollow tubes can be adjusted so as to successfully fit the two ends of the cylinder 17 shaft. The operator selects a suitable length of the cotton web cleaner 16, rotates it to a suitable position, and securely fixes it to the two mounting sleeves 15 through the bolt and nut fixings 18. The operator rotates the rotating knob 3, and this action drives the screw rod 2 to rotate on the bottom inner wall of the slide 101. The rotation of the screw rod 2 drives the screw rod 2 fixed thereon. The gear 4 on the outer wall rotates synchronously, and the gear 4 is meshed with the two racks 5, thereby driving the two racks 5 to make relative linear motion in the slide groove 101. Since the clamping block 8 is connected to the rack 5 through the connecting block 7, as the rack 5 moves towards each other, the clamping block 8 gradually approaches the axis of the cylinder 17. The arc block 801 is elastically connected to the clamping block 8 through the spring damping rod assembly 9, and can be fine-tuned according to the shaft diameter of the cylinder 17 to ensure that the clamping block 8 is tightly fitted to the axis of the cylinder 17, neither too tight nor too loose.
