Description

Technical Field

[0001] This utility model relates to the field of finishing equipment technology, specifically a polishing roller with a patting function. Background Technology

[0002] In the field of textile finishing, napping is a key process for improving the softness and surface texture of fabrics. Traditional napping equipment mainly relies on rollers (nailing rollers) with abrasive or diamond grit embedded in their surface to perform unidirectional abrasion on the fabric. However, such equipment has significant drawbacks:

[0003] (1) The current brushing rollers can only achieve basic brushing and cannot simultaneously complete the fluffing process, resulting in stiff fabric feel and insufficient fluffiness;

[0004] (2) During the brushing process, the brushing roller with conventional brushing texture is always perpendicular to the roller axis and parallel to the direction of fabric feeding. This also causes the fabric fibers to break due to continuous unidirectional force, especially for high-count yarn lightweight fabrics, such as Tencel and pure cotton, which are prone to irreversible damage.

[0005] (3) If the fabric needs to be patted to keep it fluffy according to the processing requirements, the existing patting rollers are independent single rollers or multiple rollers. When it is necessary to abrade, at least one single roller is needed to pat the fabric to keep it fluffy, and at least one single roller is needed to abrade. Thus, at least two single rollers are connected in series to achieve abrasion and patting, which leads to an increase in equipment length, increased floor space, and increased energy consumption.

[0006] Therefore, to address the shortcomings of existing finishing and patting functions, we have improved the existing roller body to simplify the finishing and patting process. Utility Model Content

[0007] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a brushing roller with a patting function that integrates brushing and patting of fabric, thereby simplifying the brushing and patting process and making the brushing process smoother.

[0008] The technical problem to be solved by this utility model is achieved through the following technical solution: a polishing roller with a patting function, which includes a roller body;

[0009] The two ends of the roller body are respectively provided with transmission shafts to facilitate transmission, and the axis of the transmission shafts is collinear with the axis of the roller body;

[0010] The outer circumferential surface of the roller is formed into a grinding circumferential surface for grinding, and a grinding part is fixedly provided on the grinding circumferential surface;

[0011] Several spiral grooves are formed on the abrasive circumferential surface of the roller, and the abrasive circumferential surface between two adjacent spiral grooves forms a patting surface for patting the fabric.

[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned abrasive roller with a patting function has an outer diameter of 195mm, a spiral groove pitch of 550mm, and the spiral groove has 4 consecutive full turns.

[0013] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned abrasive roller with a patting function, wherein the width of the patting surface is 24mm-25mm.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned abrasive roller with a patting function, wherein the abrasive part is sandpaper fixed on the abrasive circumferential surface.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are:

[0016] (1) Because a patting surface is formed on the circumferential surface of the roller, and the patting surface is a spiral arc surface, the patting parts on the arc surface cause the patting force direction of the fabric surface to present multiple angles and constantly change during the patting process. Compared with the patting trajectory of the traditional patting roller, the spiral patting trajectory is less likely to cause the fabric fibers to break due to continuous unidirectional force.

[0017] (2) By milling spiral grooves on the grinding circumference of the grinding roller to form a patting surface, the grinding + patting dual functions of a single roller are realized, completely replacing the traditional separate double roller structure, significantly reducing the footprint and transmission energy consumption, and solving the problems of the redundant equipment and complex control of the patting and grinding double roller structure in the previous finishing system.

[0022] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0023] Example 1, referring to Figure 1-3 A patting roller with a patting function includes a roller body 1, specifically a cylindrical roller body 1 structure. The outer diameter of the roller body 1 is 195mm. Its outer diameter or length can be selected according to the usage requirements and is not limited to an outer diameter of 195mm.

[0024] The two shaft end planes of the roller body 1 are respectively provided with transmission shafts 2 for easy transmission. The axis of the transmission shaft 2 is collinear with the axis of the roller body 1. The transmission shaft 2 may be provided with a keyway or a connecting key (not shown in the figure) for transmission with an external transmission structure. A grinding part for grinding is fixed on the outer circumferential surface of the roller body 1. The grinding part may be sandpaper (not shown in the figure) in the prior art.

[0025] The outer circumferential surface of the roller body 1 is formed as a brushing circumferential surface for brushing. In order to enable the roller body 1 to have a patting function, a spiral groove 3 is formed on the brushing circumferential surface. The brushing circumferential surface between two adjacent spiral grooves 3 forms a patting surface for patting the fabric. The pitch of the spiral groove 3 is 550mm. The pitch value can be customized according to the usage requirements and is not limited to a pitch of 550mm. The number of turns of the spiral groove 3 is 4 consecutive full turns. The specific number of turns is not limited to 4 full turns. The number of turns can be selected according to the usage requirements.

[0026] It needs to be explained that because there is a height difference between the milled spiral groove 3 and the outer peripheral surface of the roller body 1, the height difference between the spiral groove 3 and the patting surface 4 formed between two adjacent spiral grooves 3 actually forms a patting action on the fabric. Therefore, while the fabric is in contact with the patting surface 4, the patting operation on the fabric is achieved on the one hand, and the abrasion operation on the fabric is also achieved on the other hand.

[0027] The width of the patting surface 4 is 24mm-25mm, but its specific size is not limited to this and can be customized according to usage requirements.

[0028] The working principle of the abrasive roller with a patting function in Example 1 is as follows:

[0029] In the finishing process, the fabric comes into contact with the outer circumferential surface of the roller 1. Because the bottom of the spiral groove 3 and the surface of the patting surface 4 form a height difference, this contact process is actually a continuous dynamic patting process on the fabric. Since the outer circumferential surface of the roller 1 is fixedly equipped with abrasive parts, such as sandpaper, abrasive work is also carried out during the patting process, which maximizes the finishing efficiency of abrasive and patting, thereby increasing the fabric production capacity.
