Description

Technical Field

[0001] The utility model relates to the technical field of cloth guide rollers, and more specifically to a prestressed high-rigidity cloth guide roller. Background Art

[0002] The cloth guide roller is the most common general device in open-width dyeing and finishing equipment. Its main function is to support and guide the fabric to run in a certain direction and adjust the tension of the fabric in the running direction. Since the cloth guide roller has to bear the tension in the warp direction of the fabric for a long time in order to prevent the fabric from wrinkling during operation, the cloth guide roller is required to have a high rigidity;

[0003] The existing cloth guide roller (such as application number: CN202121325402.0, a prestressed high-rigidity cloth guide roller) adopts "hard material of stainless steel to make the roller surface part", "uses structural foam as a filling material to fill in the cavity of the cloth guide roller, and uses the low density and high strength of the structural foam to improve the rigidity of the cloth guide roller", and also provides the effect of "preventing the plastic deformation of the cloth guide roller after being stressed";

[0004] However, the above-mentioned "fabric guide roller" adopts the method of filling the cavity of the fabric guide roller with structural foam, which not only requires a large amount of material, but also the process of adding liquid is troublesome and will increase the weight to a certain extent, and has low practicality; at the same time, the effect of improving the plastic deformation recovery of rigid materials by using the method of internal filling of the material is poor. Utility Model Content

[0005] The purpose of the utility model is to solve the above technical problems and provide a prestressed high-rigidity cloth guide roller.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model proposes a prestressed high-rigidity cloth guide roller, comprising a roller tube and a roller shaft arranged centrally inside the roller tube, the roller tube and the roller shaft being fixed by a support member, a reinforcing component for improving the overall surface hardness of the roller tube is provided on the roller tube, and an elastic supporting force is provided by the support member in the direction of the roller tube toward the roller shaft to prevent the roller tube from deforming.

[0008] As a preferred technical solution of the utility model, the support members are provided in multiple groups and are evenly distributed along the two ends of the roller tube.

[0009] As a preferred technical solution of the utility model, the support member includes a ring sleeve fixed around the outside of the roller shaft, a ring cavity is provided on the outer periphery of the ring sleeve, and a ring plate fixed to the reinforcing component is provided on the inner side of the ring cavity, and the ring plate and the ring cavity are elastically connected by an elastic member.

[0010] As a preferred technical solution of the utility model, the elastic members are provided in multiple groups and are evenly distributed between the ring plate and the ring cavity.

[0011] As a preferred technical solution of the utility model, the reinforcing component includes a heat treatment layer fixedly arranged on the surface of the roller tube, a chrome plating layer fixedly arranged on the surface of the heat treatment layer, and the heat treatment layer is a carburizing treatment layer or a nitriding treatment layer.

[0012] As a preferred technical solution of the utility model, the reinforcing component also includes a wear-resistant layer fixedly arranged on the outside of the chrome-plated layer, and the outer side of the ring plate is fixed to the wear-resistant layer.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting a reinforcement component on the outer surface of the roller tube, the heat treatment layer and the chrome plating layer in the reinforcement component are sequentially arranged on the surface of the roller tube, so that the hardness can be enhanced, and the overall weight is extremely low, the manufacturing process is simple, and the practicality is high;

[0015] At the same time, the roller tube adopts a support member to directly elastically support the roller shaft, and when the roller tube surface is subjected to a force close to the roller tube deformation, an elastic buffer is provided to protect the roller tube.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0020] Embodiment 1:

[0021] like Figure 1As shown, this embodiment proposes: a prestressed high-rigidity cloth guide roller, comprising a roller tube 1 and a roller shaft 2 centrally arranged inside the roller tube 1 (as shown in the figure, the tube end of the roller tube 1 faces left and right, and the roller shaft 2 is centrally inserted into the roller tube 1);

[0022] The roller tube 1 and the roller shaft 2 are fixed by a support member 3 to stabilize the relative position of the roller tube 1 and the roller shaft 2;

[0023] Among them, the support members 3 are provided in multiple groups and are evenly distributed along the two ends of the roller tube 1 (multiple groups are reasonably provided to improve the stability of the overall support and increase the overall strength);

[0024] The roller tube 1 is provided with a reinforcing component 4 for increasing the overall surface hardness thereof, thereby increasing the strength in use;

[0025] In order to implement the above-mentioned strengthening component 4, it is proposed that Figure 1 As shown, the specific structure and composition of the reinforcement component 4 can be as follows: the reinforcement component 4 includes a heat treatment layer 41 fixedly arranged on the surface of the roller tube 1, and the heat treatment layer 41 is a carburizing treatment layer or a nitriding treatment layer (carburizing treatment: forming a hard and wear-resistant carbide layer on the outer surface of the roller tube 1, which can significantly improve the surface hardness and wear resistance);

[0026] The chrome-plated layer 42 is fixedly provided on the surface of the heat-treated layer 41 (the chrome-plated layer 42 is provided on the surface of the heat-treated layer 41 to obtain the effects of improving hardness, corrosion resistance, wear resistance, etc.).

[0027] Among them, the reinforcing component 4 also includes a wear-resistant layer 43 fixed to the outside of the chrome-plated layer 42, and the outside of the ring plate 32 is fixed to the wear-resistant layer 43 (the wear-resistant layer 43 is a polytetrafluoroethylene layer, etc., which can reduce the friction coefficient and protect the contacting cloth; it can effectively prevent the fabric from sticking or adsorbing on the roller surface in complex environments such as high temperature and high humidity, ensuring the smooth passage of the fabric and improving production efficiency).

[0028] Embodiment 2:

[0029] like Figure 1 As shown, the difference from Example 1 is that the support member 3 provides elastic supporting force in the direction of the roller tube 1 toward the roller axis 2 to prevent the roller tube 1 from deforming (when the surface of the roller tube 1 is subjected to a force close to the deformation of the roller tube 1, an elastic buffer is provided to protect the roller tube 1).

[0030] In order to implement the above-mentioned support member 3, it is proposed that Figure 1 As shown, the specific structure and composition of the support member 3 can be as follows: the support member 3 includes a ring sleeve 31 fixedly arranged outside the roller shaft 2, and a ring cavity is arranged outside the ring sleeve 31 (as shown in the figure, the ring cavity is arranged at the position of the ring sleeve 31 outside the roller shaft 2);

[0031] An annular plate 32 fixed to the reinforcing assembly 4 is provided inside the annular cavity. The annular plate 32 and the annular cavity are elastically connected by an elastic member 33 (the elastic member 33 may be a spring, etc.), providing elastic support for the annular plate 32 in the annular cavity.

[0032] Among them, the elastic members 33 are provided in multiple groups and are evenly distributed between the ring plate 32 and the ring cavity (multiple groups are reasonably arranged to improve the elastic stability of the overall support and improve the balancing force). The elastic deformation force of the multiple groups of elastic members 33 in the ring cavity on the ring plate 32 is not greater than the deformation force of the roller tube 1, providing protection.
