Description

Technical Field

[0001] This utility model relates to the technical field of winding machines, specifically to roller pressing scrapers. Background Technology

[0002] Currently, sliver lap machines are widely used in the textile industry for processing cotton fabrics, especially in the production process of rolling or compacting cotton fabrics, where pressure rollers play a crucial role. The main function of pressure rollers is to ensure the smoothness of cotton fabrics, while simultaneously making the fabric more compact through high pressure.

[0003] However, when producing some cotton-wax-heavy fabrics, the bakelite blades currently used are difficult to clean the pressure rollers completely, which can easily cause the pressure rollers to become entangled, thus affecting the production efficiency of the sliver lap machine and the production quality of the textiles.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a roller-pressed scraper.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a roller-type scraper, comprising a pressure roller cylinder mounted on a winding machine for winding or pressing cotton textiles, a fixed frame mounted on one side of the pressure roller cylinder, and a scraper detachably mounted on the fixed frame, further comprising:

[0007] A felt roll, wrapped around the outside of the scraper, is used to rub and clean the cotton wax adhering to the outer surface of the pressure roller.

[0008] The drive assembly includes a mounting plate correspondingly disposed on the fixed frame and a rotating drum rotatably disposed within the mounting plate and connected to one end of the scraper. Rotating the rotating drum causes the felt roll to move to one side through friction between the rotating drum and the felt roll, thereby moving the felt roll on the scraper at the position used to scrape off the cotton wax.

[0009] Furthermore, the scraper has an arc-shaped end at one end away from the rotating drum, and the outer part of the arc-shaped end is rubbed and bonded to the corresponding contact portion of the felt roll.

[0010] Furthermore, a circular handle is provided at one end of the rotating drum and in a slot on the mounting plate;

[0011] The circular handle is used to drive the felt roll that is frictionally connected to the rotating drum to move to one side.

[0012] Furthermore, the mounting plate is provided with several comb teeth evenly distributed at the ends of the corresponding felt rolls;

[0013] The comb teeth are used to remove the cotton wax that adheres to the felt roll after cleaning.

[0014] Furthermore, the two ends of the felt roll that are joined together are provided with corresponding Velcro fasteners.

[0015] Furthermore, the mounting plate has screw holes at the end that is fixed to the fixing frame.

[0016] Compared with the prior art, this utility model has the following beneficial effects: The utility model, through the provided felt roll and the scraper contained within the felt roll, can effectively clean the cotton wax adhering to the pressure roller simultaneously after the pressure roller rolls up or compacts the cotton fabric, improving the cleaning effect on the pressure roller and providing a better anti-winding effect, thus ensuring the output of the sliver lap machine; furthermore, through the provided drive component, the felt roll can be periodically moved on the scraper at the position used to remove cotton wax, maintaining multiple surfaces in contact and friction with the pressure roller, further achieving a good cleaning effect.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figure 1-3 As shown, this utility model of a roller-pressed scraper is used on a winding machine. It includes a pressure roller mounted on the winding machine for winding or pressing cotton fabric, a fixed frame 1 mounted on one side of the pressure roller, and a scraper 2 detachably mounted on the fixed frame 1. It also includes:

[0024] The felt roll 3 is wrapped around the outside of the scraper 2 and is used to rub and clean the cotton wax adhering to the outer surface of the pressure roller.

[0025] The drive assembly 4 includes a mounting plate 41 correspondingly disposed on the fixed frame 1 and a rotating drum 42 rotatably disposed within the mounting plate 41 and connected to one end of the scraper 2. Rotating the rotating drum 42 causes the felt roll 3 to move to one side through friction between the rotating drum 42 and the felt roll 3, thereby moving the felt roll 3 to the position on the scraper 2 used to scrape off the cotton wax.

[0026] In specific implementation, by using a fixed frame 1 installed on one side of the pressure roller facing the roller surface and a scraper 2 detachably installed on the fixed frame 1, the pressure roller will roll up or compact the cotton textiles during the winding machine operation. For some fabric varieties with heavy cotton wax, the cotton wax will transfer and adhere to the outer surface of the pressure roller during the rolling or compaction process. At this time, the scraper 2 located on the adjacent side will simultaneously scrape off and clean the cotton wax adhering to the surface of the pressure roller. The friction method adopted by the felt roll 3 covering the scraper 2 improves the cleaning effect on the pressure roller and solves the adverse effects of cotton wax on the pressure roller.

[0027] The mounting plate 41, which is screwed onto the fixed frame 1, and the rotating drum 42, which is rotatably mounted at both ends inside the mounting plate 41, can drive the felt roll 3 to move on the scraper 2 at the position used to scrape off the cotton wax under the friction between the rotating drum 42 and the felt roll 3 during the periodic operation of the external rotating drum 42. This keeps multiple surfaces of the felt roll 3 in contact with the pressure roller and friction, thereby achieving a better cleaning effect.

[0028] It should be noted that scraper 2 uses a bakelite blade structure.

[0029] In one embodiment, an arc-shaped end 21 is provided at the end of the scraper 2 away from the rotating drum 42, and the outer part of the arc-shaped end 21 is rubbed and bonded to the corresponding contact portion of the felt roll 3. This design, with the arc-shaped end 21 integrally formed at the end of the scraper 2 away from the rotating drum 42, and the outer shape of the arc-shaped end 21 fitting and bonded to the inner contact portion of the felt roll 3, allows the arc-shaped end 21 to function as a "driven roller structure" of a "conveyor belt" when the rotating drum 42 rotates, thus assisting the felt roll 3 in moving outside the scraper 2, achieving a structure similar to a "conveyor belt".

[0030] It should be noted that one end of the felt roll 3 is tightly wrapped around the rotating drum 42. The friction of the rotating drum 42 directly acts on the felt roll 3. The rotating drum 42 will contact the felt roll 3 through the friction of its surface, generating sufficient traction force to make the felt roll 3 start to move.

[0031] Furthermore, the inner surface of the felt roll 3 is covered with a metal support surface, which provides greater friction when it comes into contact with the scraper 2, which has a bakelite blade structure. The felt roll 3 is wrapped around the outside of the scraper 2 to maintain appropriate tension, ensuring sufficient friction and preventing slippage.

[0032] In one embodiment, a circular handle 421 is provided at one end of the rotating drum 42 and slotted on the mounting plate 41;

[0033] The circular handle 421 is used to drive the felt roll 3, which is frictionally connected to the rotating drum 42, to move to one side. This design increases the external operating area of ​​the rotating drum 42 by using the circular handle 421 fitted on one end of the rotating drum 42, making it more convenient and time-saving to rotate the rotating drum 42.

[0034] In one embodiment, a plurality of comb teeth 43 are evenly provided on the mounting plate 41 corresponding to the end of the felt roll 3;

[0035] The comb teeth 43 are used to remove the cotton wax adhering to the felt roll 3 after cleaning. This design, with several comb teeth 43 evenly spaced at the ends of the felt roll 3 on the mounting plate 41 through turning, allows the comb teeth 43 to penetrate deep into the fiber gaps on the surface of the felt roll 3, grasping and peeling off the cotton wax particles as they pass over the areas where cotton wax adheres, thus extending the service life of the felt roll 3.

[0036] In one embodiment, the two ends of the felt roll 3 that are joined together are provided with corresponding Velcro 31. With this design, by sewing the "hook side" and "loop side" of the Velcro 31 to the two ends of the felt roll 3 that are joined together, when the two sides are facing each other, the "hook side" will grab the fibers on the "loop side" to form a tight connection to provide a temporary adhesive effect. When disassembling, it can be directly separated, which is simple to operate.

[0037] In one embodiment, the mounting plate 41 has screw holes at the end that is fixed to the fixing bracket 1. This design allows the drive assembly 4 to be fixed to the fixing bracket 1 by screwing in screws into the screw holes machined at the connection positions of the mounting plate 41 and corresponding to the fixing bracket 1.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0039] It should be noted that if the embodiments of this utility model involve directional indicators, such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0040] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, "several" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
