Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to a heald piece processing device for a drawing-in machine. Background Art

[0002] In the textile production process, there is a process called drawing in. The process of drawing in is usually to pass each warp thread through the heald eyelet of the heald in the order required by the process. The main purpose is to use the heald to drive the warp thread to move up and down during the weaving process, so that the upper and lower openings and closings of different warps can be moved; the weft thread passes through the middle when the warp thread moves up and down, completing the weaving process. This process is traditionally completed manually, but the manual efficiency is low. The labor intensity is high. With the development of automation, the drawing in machine has gradually replaced the traditional manual drawing in, which has greatly improved the work efficiency.

[0003] The heald drawing machine is an automated device used to automatically thread the yarn into the heald and the dropper. It uses mechanical operation to lift the heald and uses the hanging needle to pass the warp yarn through the heald eye on the heald to complete the drawing. For the heald that has been drawn into the heald, a piston is usually used to push it forward and hang it on the heald. The heald is also called the heald bar. Since the heald is the carrier on which the heald is hung after the heald is drawn into the heald, the installation position cannot be too far, otherwise the piston cannot push the heald to hang on the heald. However, if it is installed too close, it will contact with the hanging needle during the drawing, causing damage to the hanging needle. Therefore, a processing device for the installation of the heald is usually provided. Its main structure is an aluminum plate with threaded holes. The aluminum plate is installed on the heald drawing machine with screws. The heald is directly pressed against the aluminum plate for installation. The installation distance of the heald is determined by the thickness of the aluminum plate. After installation, the aluminum plate is removed to complete the installation of the heald.

[0004] Such a design simplifies the installation steps and is highly practical. However, since the heald is made of thin stainless steel, the aluminum plate on the processing device is cut each time the heald is pressed against the aluminum plate for installation, which causes grooves and deformation on the processing device during installation. The installation is not precise enough, so the processing device has to be replaced, causing a large amount of work damage, increasing the maintenance cost of the heald drawing machine, and further increasing the production cost of the enterprise. Utility Model Content

[0005] The utility model aims to provide a heald processing device for a drawing-in machine, so as to solve the technical problem that the processing device for adjusting the installation distance of the healds in the prior art mentioned above is damaged by the heald cutting and needs to be frequently replaced.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a heald piece processing device of a heald drawing machine, comprising a thickness plate, one side of the thickness plate is provided with an anti-cutting plate with a hardness greater than that of the heald strip, and the other side is provided with a connecting device, and the anti-cutting plate is fixedly connected to the thickness plate by screws.

[0007] The beneficial effects of this embodiment are:

[0008] 1. The aluminum plate of the heald processing device used in the prior art has low strength and is soft. It is easily cut and damaged during multiple installations and needs to be replaced frequently. The technical solution of the present application is designed with a thickness plate and an anti-cutting plate. The thickness of the thickness plate is used to provide the installation distance of the heald, and the anti-cutting plate is fixed on its surface with screws. The anti-cutting plate has high strength and less wear when installed multiple times, making it more durable. When the anti-cutting plate is damaged, only the anti-cutting plate needs to be replaced, and there is no need to discard the entire processing device.

[0009] 2. In the prior art, the processing device is an aluminum plate, which has low strength and is easily damaged by the cutting of the heald during installation. If the aluminum plate is simply replaced with a stronger stainless steel material, the stainless steel has high strength and hardness greater than the hardness of the heald, and will not be worn by the cutting of the heald. However, the processing device for installing the entire heald is a rectangular block with a length of 23.6 cm, a width of 4.0 cm and a thickness of 1.0 cm. In addition, the rectangular block is connected to the frame, which is too heavy. Most of the workers in the textile industry are female workers with low arm strength. During installation, the entire device must be installed deep under the frame with one hand, which is difficult for female textile workers to operate. If it is designed as a hollow structure for easy operation, it will also be deformed by the heald multiple times, and the correct installation distance cannot be provided. However, the present application utilizes a multi-layer structure, and the thickness layer uses a material with a lower density, such as aluminum, and the anti-cutting layer uses a material with a high hardness, such as stainless steel. In this way, female textile workers can hold the device with one hand and install it deep into the frame, and can also avoid the device being deformed by the heald cutting, thereby causing a large amount of loss.

[0010] Furthermore, the connecting device includes an adsorption magnet. In the prior art, bolts are used to install the processing device on the frame. Therefore, during operation, the textile workers need to squat under the frame, hold the device with one hand, and tighten the bolts with the other hand. However, the processing device in the present application is small in mass, and an adsorption magnet is designed on the side connected to the frame. The adsorption magnet is directly adsorbed and installed on the frame by utilizing its magnetism. There is no need for the female workers to squat and tighten the bolts. The operation is simple and efficient, and the female workers are prevented from being under the frame, which is safer.

[0011] Furthermore, the thickness plate is provided with a connection groove, the connection groove is provided with a connection flange, the adsorption magnet is provided with a connection protrusion, and the adsorption magnet is installed in the connection groove. Since the magnet and the aluminum plate cannot be welded, the adsorption magnet is embedded in the thickness plate by using the connection groove, so that the adsorption magnet is exposed and is more stable when installed on the frame.

[0012] Furthermore, a limiting rod for limiting the position of the adsorption magnet is provided on the connecting flange to prevent the adsorption magnet from slipping.

[0013] Furthermore, it also includes a limit bar, the limit bar wraps the two ends of the adsorption magnet, and the limit bar is fixedly connected to the thickness plate. The magnet is directly mounted on the thickness plate using the limit bar, which has a simple structure and avoids grooving the thickness plate.

[0014] Furthermore, the thickness of the plate is less than 3g / cm 3 The device size and density of the device, which is 23.6cm long, 4.0cm wide and 1.0cm thick, is less than 3g / cm 3 The design makes the overall weight less than 283.2g, which is convenient for female workers to operate with one hand.

[0019] The following is further described in detail through specific implementation methods:

[0020] The figure marks in the drawings of the specification include: thickness plate 1, connecting groove 12, connecting flange 13, limiting rod 131, limiting strip 14, anti-cutting plate 2, screw 21, adsorption magnet 3, connecting protrusion 31.

[0021] Example 1

[0022] As attached Figures 1 to 3 As shown: A heald processing device for a drawing machine includes a thickness plate 1. The density of the thickness plate 1 is less than 3, so its material can be selected from aluminum plates, wooden boards and other materials with low density. Its main structure is a rectangular block structure. An anti-cutting plate 2 is provided on the right side of the thickness plate 1. The anti-cutting plate 2 is a thin plate structure, so it accounts for a very small proportion of the mass of the entire processing device, making the mass of the entire processing device small, which is convenient for female workers to operate with one hand. The hardness of the anti-cutting plate 2 is greater than the hardness of the heald strip, and stainless steel is used. The anti-cutting plate 2 is fixedly connected to the thickness plate 1 by screws 21. The screws also facilitate the replacement of the anti-cutting plate 2 in later maintenance.

[0023] like Figure 1 , Figure 3As shown, a connecting groove 12 is opened on the left side of the thickness plate 1. Two connecting grooves 12 are provided at the upper and lower ends of the thickness plate 1. The two structures are completely the same. The upper and lower sides of the surface of the connecting groove 12 are provided with connecting flanges 13. The connecting flanges 13 and the thickness plate 1 are an integral structure and do not need to be connected. An adsorption magnet 3 is embedded in the connecting groove 12. The cross section of the adsorption magnet 3 is a convex shape. The protruding parts on the upper and lower sides are connecting convex heads 31. The connecting convex heads 31 are limited in the connecting groove 12 by the connecting flanges 13, and then the adsorption magnet 3 is limited in the connecting groove 12. A limiting rod 131 is also provided between the upper and lower connecting flanges 13 of a connecting groove 12. The two ends of the limiting rod 131 are fixed to the connecting flanges with screws to limit the adsorption magnet 3 in the connecting groove 12 without displacement.

[0024] Example 2

[0025] Example 2 Figure 4 As shown, the difference from Example 1 is that the adsorption magnet 3 is a rectangular bar structure, and the adsorption magnet 3 is fixed to the left side of the thickness plate 1 by the limiting bar 14. The limiting bar 14 wraps the front and rear ends of the adsorption magnet 3, and the two ends of the limiting bar 14 extend and are directly fixed to the thickness plate 1 by screws. Compared with Example 1, Example 2 avoids grooving on the thickness plate 1, and the structure of the adsorption magnet 3 is simpler, and processing of the adsorption magnet 3 is also avoided.

[0026] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
