Technical Field
[0001] This utility model belongs to the field of carding machine technology, and more specifically, it relates to a double-doffer carding device for a carding machine. Background Technology
[0002] Carding machines are key equipment in the textile industry. Their core function is to comb the fiber raw materials to make them into a uniform and clean fiber web, laying the foundation for subsequent spinning processes. The doffer, as an important component of the carding machine, mainly functions to peel off the fiber layer on the surface of the cylinder and form a fiber web through combing and cohesion.
[0003] Application number CN201820152035.0 discloses a novel double doffer carding machine comprising: a base beam, a main frame, a lower connecting frame, a vertical support, an upper connecting frame, a stripping roller, a randomizing roller, a doffer, a dust suction hood, a wind deflector roller, a movable cover plate, a cylinder wall panel, a cylinder, a fixed cover plate, a cotton opening roller, a cotton feeding roller, a cotton feeding plate, and a base beam. The base beam is fixedly connected to the main frame, and the main frame and the lower connecting frame are connected together with high-strength screws and tapered pins to form a single unit. The lower connecting frame is fixedly connected to one end of the vertical support. The other end of the upright support is fixedly connected to the upper connecting frame. The dust hood is detached and connected to the upper connecting frame. The cylinder roller is installed on the main frame. The movable cover plate carding area is installed on the cylinder roller. The bottom beam, main frame, upper connecting frame and lower connecting frame together form the base. The base length is 1.88m-2.95m and the frame height is 950mm. This utility model can accommodate two sets of working rollers at the same time by modifying the main frame and adding upper and lower connecting frames, making the double doffer carding machine more convenient to operate, install and maintain.
[0004] Based on the above patent search and understanding of the application of double doffer carding in existing carding machines: Currently, there is a lack of efficient collection devices for dust, short fibers and other impurities generated during the carding process of carding machines, which can easily cause a dirty and messy working environment and may affect the stability of equipment operation. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a double-doffer carding device for a carding machine, which solves the problem that existing carding machines lack efficient collection devices for dust, short fibers, and other impurities generated during the carding process, easily causing a dirty and messy working environment and potentially affecting the stability of equipment operation.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A carding machine double-doffer carding device includes a frame; a conveyor belt is provided at the top rear end of the frame, and a protective cover is provided at the top front end of the frame. The protective cover is located at the front end of the conveyor belt. A rectangular groove is opened at the top middle of the protective cover, and a vacuum cleaner is fixedly installed in the rectangular groove of the protective cover. A conveying pipe is provided at the top of the vacuum cleaner, and the vacuum cleaner is located at the top front end of the frame.
[0008] According to one embodiment of the present invention, a limiting roller is rotatably connected to the upper and lower sides of the inner rear end of the protective cover, and a motor is fixedly installed at the lower middle position of the left side of the protective cover.
[0009] According to one embodiment of the present invention, the motor shaft is fixedly connected to the left side of the combing roller A, the combing roller A is rotatably connected to the lower middle position inside the protective cover, and the combing roller A is located directly below the vacuum cleaner.
[0010] According to one embodiment of the present invention, a combing roller B is rotatably connected to the upper middle position inside the protective cover, and the combing roller B is located directly above the combing roller A.
[0011] According to one embodiment of the present invention, the left and right sides of the carding roller A and the carding roller B are respectively provided with carding brushes with a reverse spiral design.
[0012] According to one embodiment of the present invention, the right side of the carding roller A and the carding roller B are sleeved inside the belt.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By arranging carding rollers A and B vertically, a dual carding path is formed. Combined with a reverse spiral carding brush, the fiber raw material can be cross-carded from different directions, effectively dispersing fiber clumps, improving fiber straightness and parallelism, and reducing cotton knots and short fibers.
[0015] 2. The vacuum cleaner is fixed in the rectangular groove at the top of the protective cover. It can directly adsorb the impurities generated during the combing process and discharge them through the conveying pipe to avoid secondary pollution of impurities, improve the workshop environment, reduce the accumulation of impurities inside the equipment, and reduce the risk of failure.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0025] Example:
[0026] As attached Figure 1 To be continued Figure 4 As shown:
[0027] This utility model provides a double-doffer carding device for a carding machine, including a frame 1; a conveyor belt 101 is provided at the rear end of the top of the frame 1, and a protective cover 102 is provided at the front end of the top of the frame 1. The protective cover 102 is located at the front end of the conveyor belt 101. A rectangular groove is provided at the middle of the top of the protective cover 102, and a vacuum cleaner 2 is fixedly installed in the rectangular groove of the protective cover 102. A conveying pipe 201 is provided at the top of the vacuum cleaner 2, and the vacuum cleaner 2 is located at the front end of the top of the frame 1.
[0028] The protective cover 102 has a limiting roller 103 rotatably connected to the upper and lower sides of the inner rear end. A motor 104 is fixedly installed at the lower left side of the protective cover 102. The rotating shaft of the motor 104 is fixedly connected to the left side of the combing roller A105. The combing roller A105 is rotatably connected to the lower inside of the protective cover 102 and is located directly below the vacuum cleaner 2.
[0029] The protective cover 102 is rotatably connected to the upper middle position of the carding roller B106. The carding roller B106 is located directly above the carding roller A105. The carding roller A105 and the carding roller B106 are respectively provided with carding brushes with a reverse spiral design on the left and right sides. The right side of the carding roller A105 and the carding roller B106 is sleeved inside the belt 107.
[0030] When using:
[0031] Fix the equipment frame 1 at the designated position on the carding machine production line, ensuring that the conveyor belt 101 is aligned with the upstream cotton feeding equipment to facilitate the smooth transport of the cotton layer. Next, introduce the cotton layer into the middle position between the two limit rollers 103 and into the middle position inside the carding roller A105 and carding roller B106, and then pull it out.
[0032] When motor 104 is turned on, it drives carding roller A105 to rotate. Since carding roller A105 and carding roller B106 are connected by belt 107, carding roller B106 will also rotate. The reverse spiral carding brushes on the two carding rollers start to work and card the fiber raw material that enters the protective cover 102. During this process, vacuum cleaner 2 is started to suck up the dust, short fibers and other impurities generated during the carding process and discharge them through conveyor pipe 201 to the collection position to keep the carding environment clean.
