[0002] The cotton combing roller is also called the licker-in roller, and has a cotton combing needle on its surface. The licker-in roller drives the cotton combing needle to comb the cotton balls and remove impurities in the cotton balls through rotation. In the continuous cotton combing process, cotton wool and the like will be entangled and entangled on the cotton combing needle, making the cotton combing effect of the cotton combing needle poor, and even causing the cotton combing needle to be stuck in the cotton wool and break. Manual cleaning is time-consuming and laborious, and it is easy to injure the staff, and it is difficult to clean it. In the prior art, there is a device that uses a cam to push the cotton combing needle to make a reciprocating motion from the inside to the outside, and uses the surface of the cotton combing roller to remove the entangled cotton wool. However, this structure can only push the cotton wool to a position near the needle tip, and cannot push it out of the cotton combing needle. Moreover, if the cotton combing needle completely enters the cotton combing roller, there is a risk of friction or collision with the cotton combing roller during the reciprocating stroke;

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0025] Specific implementation examples Figure 1 , 2 , 3, 4, 5 and 6, a textile combing roller, characterized in that:

[0026] The combing roller 1 comprises a cylindrical and hollow roller body 101, on which combing needles 102 are fixedly connected, and through slots 103 are provided between each row of combing needles 102; connectors 104 are fixedly connected at both ends of the roller body, and the connectors are transmission-connected to an external transmission device;

[0027] The telescopic structure 2 is inserted into the through slot 103, and includes a telescopic plate 201 that penetrates the through slot 103 and an arc-shaped bottom plate 202 at the bottom of the telescopic plate 201; a first elastic member 203 is connected between the arc-shaped bottom plate 202 and the inner surface of the roller body 101, and a plurality of arc-shaped bottom plates are in contact to form a hollow cylindrical structure;

[0028] The driving structure 3 includes a telescopic rod 301 and an electric push rod 302. The telescopic rod 301 includes a conical section 303 and a cylindrical section 304. The diameter of the cylindrical section 304 is larger than the diameter of the hollow cylindrical structure formed by the contact of multiple arc-shaped bottom plates, and the front end diameter of the conical section 303 is smaller than the diameter of the hollow cylindrical structure formed by the contact of multiple arc-shaped bottom plates. The telescopic rod 301 reciprocates inside the hollow cylindrical structure formed by the contact of multiple arc-shaped bottom plates.

[0029] Under the action of the driving structure 3, the telescopic plate 101 performs a linear reciprocating motion and can easily enter the diameter of the hollow cylindrical structure formed by contacting multiple arc bottom plates 202 through the tapered section, squeezing the arc bottom plates 202 to diffuse outward and push out the cotton wool. After the telescopic rod 101 retracts, the first elastic member 203 pushes the arc bottom plate 202 to return to its original position. The structure is simple and convenient, easy to use, and can be cleaned while combing cotton.

[0030] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the telescopic plate 201 travels to a maximum of 5 mm beyond the top of the carding needle 102, and the telescopic plate 201 travels to a minimum of 5 mm beyond the surface of the roller body 101.

[0031] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the arc bottom plates 202 are connected with second elastic members 204. The second elastic members 204 can connect the arc bottom plates 202 to avoid dislocation and deformation.

[0032] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the top surface of the telescopic plate 201 has a push plate 205, and the arc-shaped push plate 205 matches the outer surface of the roller body 101. The arc-shaped push plate 205 matches the outer surface of the roller body 101 to prevent cotton wool from rolling into the escalator 101 along the gap between the two.

[0033] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the push plate 205 is at least 5 mm away from the combing needles 102 on both sides. Leaving a certain distance can avoid bumping against the combing needles 102 and damaging the combing needles 102.

[0034] In order to avoid cotton wool from sticking to the push plate 205, the outer surface of the push plate 205 is a smooth metal surface. The smooth metal surface can prevent cotton wool from sticking to the push plate 205.

[0035] like Figure 1 , 2 As shown in , 3, 4, 5 and 6, the first elastic member 203 is a spring, and two ends of the first elastic member 203 are fixedly connected to the inner surface of the roller body 101 and the arc-shaped bottom plate respectively.

[0036] like Figure 6 As shown, the second elastic member 204 is a spring, and grooves 206 are provided on both sides of the arc bottom plate. Both ends of the second elastic member 204 are respectively fixedly connected in the opposite grooves 206 of two adjacent arc bottom plates 202 .

[0037] Working principle: The combing roller 1 drives the combing needles 102 on the rolling ladder 101 to comb the cotton balls. The driving structure 3 is controlled by a pre-set program to make the telescopic rod 301 reciprocate. The front end diameter of the conical section 303 of the telescopic rod 301 is smaller than the diameter of the hollow cylindrical structure formed by the contact of multiple arc bottom plates, which can facilitate the insertion of the telescopic rod 301 and squeeze the telescopic structure 2 outward, so that the arc bottom plate 202 drives the telescopic plate 201 to extend outward in a circular diffusion shape and compress the first elastic member 203. The cotton wool between the carding needles 102 is pushed out; the telescopic rod 301 is pulled out, and the arc-shaped bottom plate 202 is reset under the elastic force of the first elastic member 203. The interval of extending and retracting the telescopic rod 301 is determined according to the actual application to avoid squeezing the cotton balls as much as possible; the arc-shaped bottom plate 202 is squeezed by the linear reciprocating motion of the telescopic rod 301, so that the telescopic plate 201 performs a reciprocating motion to push out the cotton wool between the carding needles 102. The structure is simple, and there is no need to stop the machine to clean the carding roller 1, thereby reducing time waste.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
