Description

Technical Field

[0001] The utility model relates to the technical field of disposable glove production equipment, in particular to a conveyor belt for disposable glove production and a conveying device using the conveyor belt. Background Art

[0002] Disposable PE gloves are made of polyethylene blow mold, with the characteristics of low cost, good softness, strong tensile strength, not easy to break, etc., which can not only avoid cross infection, but also greatly save replacement costs. In recent years, they have been used more and more widely in our daily life, especially in some industries with high frequency of gloves replacement, such as medical industry, laboratory, food processing industry and other industries with high hygiene requirements.

[0003] In the production process of disposable PE gloves, the film raw material is usually intermittently punched to make the film raw material evenly spaced with glove prototypes in the shape of human hands, and then the glove prototypes are torn off the film raw material to make PE gloves; the PE gloves are then transported to the packaging room for packaging through a conveyor. However, in the current conveyor device, the surface of the conveyor belt is relatively smooth and there is no limit device, so that when the conveyor device is tilted, the gloves are easy to slide down, which is not conducive to the transportation of the gloves. In addition, after the gloves slide down, it is easy to cause multiple gloves to stack together, and the gloves still have a certain temperature after demolding, which may cause adjacent gloves to stick to each other, leaving marks on the surface of the gloves, affecting the appearance of the gloves. In severe cases, the gloves may be damaged and affect the product quality. Utility Model Content

[0004] In order to overcome the above-mentioned problems existing in the prior art, the present application provides a conveyor belt for the production of disposable gloves. The conveyor belt for the production of disposable gloves of the present application is cast and molded by polyurethane material, and has good wear resistance and high temperature resistance. It is not easy to wear after long-term use and has a long service life. By setting a group of spaced strip protrusions on the outer peripheral surface of the conveyor belt body, the friction between the gloves and the conveyor belt surface can be increased, so that when the conveyor belt is tilted, the gloves are not easy to slide down and can be stably placed on the conveyor belt. A ventilation flow channel can also be formed between the gloves and the conveyor belt body to facilitate the heat dissipation of the gloves during the transportation process, so as to prevent the adhesion of multiple gloves after being stacked together. In addition, the conveyor belt transmits power by meshing the annular belt teeth with the annular tooth grooves on the pulley, and the transmission is relatively stable and the running speed is relatively fast. Correspondingly, the present application also provides a conveying device using the conveyor belt.

[0005] For the conveyor belt, the technical solution of this application is:

[0006] A conveyor belt for producing disposable gloves comprises a conveyor belt body; a group of strip-shaped protrusions spaced apart along the length direction of the conveyor belt body are provided on the outer circumferential surface of the conveyor belt body; a group of annular belt teeth spaced apart along the width direction of the conveyor belt body are provided on the inner circumferential surface of the conveyor belt body, and an annular groove is formed between two adjacent annular belt teeth; the annular belt teeth are used to mesh with annular tooth grooves on a pulley to transmit power; the conveyor belt body, the strip-shaped protrusions and the annular belt teeth are integrally cast and molded by polyurethane material; a frame is provided between the strip-shaped protrusions and the conveyor belt body.

[0007] Compared with the prior art, the conveyor belt for producing disposable gloves of the present application is provided with a group of strip-shaped protrusions on the outer peripheral surface of the conveyor belt body to increase the friction between the gloves and the conveyor belt surface, reduce the possibility of the gloves sliding down due to gravity during the conveying process of the conveyor belt, so that when the conveyor belt is tilted, the gloves can also be stably placed on the conveyor belt, which is conducive to the conveying of the gloves; and the strip-shaped protrusions are distributed at intervals, and a ventilation flow channel can be formed between the gloves and the conveyor belt body, which is convenient for heat dissipation of the gloves during the conveying process, so as to prevent the phenomenon of adhesion of multiple gloves after being stacked together, and ensure the product quality; the conveyor belt is provided with a group of annular belt teeth on the inner peripheral surface, which are used to mesh with the annular tooth grooves on the pulley to transmit power during operation, so as to improve the transmission stability and running speed of the conveyor belt; in addition, the conveyor belt body, the strip-shaped protrusions and the annular belt teeth are integrally cast and molded with polyurethane material, which has good wear resistance and high temperature resistance, is not easy to wear after long-term use, and has a long service life.

[0008] As an optimization, in the aforementioned conveyor belt for producing disposable gloves, the skeleton includes an adhesive layer provided between the strip-shaped protrusions and the conveyor belt body; and a tensile cord is embedded in the adhesive layer. Providing the tensile cord in the skeleton is beneficial to enhancing the tension and bending resistance of the conveyor belt and extending its service life. In addition, the design of the adhesive layer improves the peeling strength between the tensile cord and the conveyor belt body and the strip-shaped protrusions on both sides, thereby avoiding the tensile cord from falling off during the use of the conveyor belt. Furthermore, the tensile cord can be a Kevlar cord. The Kevlar cord has high strength and strong tensile resistance, thereby being able to improve the tensile strength of the conveyor belt and further ensure its service life.

[0009] As an optimization, in the aforementioned conveyor belt for producing disposable gloves, the cross section of the annular belt teeth is V-shaped, that is, the ends of the annular belt teeth are thin and the roots are thick. In this case, the notch size of the annular groove will be relatively large, so that it is easier to insert the annular gear teeth on the pulley into the corresponding annular groove during assembly.

[0010] As an optimization, in the aforementioned conveyor belt for producing disposable gloves, the length of the strip protrusion is consistent with the width of the conveyor belt body. In this case, the manufacturing is relatively simple. Furthermore, the two end faces of the strip protrusion are trapezoidal surfaces that are small at the top and large at the bottom. In the actual production process, the edge of the skeleton may be exposed a little. After the two end faces of the strip protrusion are cut into a trapezoid, the exposed edge of the skeleton can be folded upwards, and will not interfere with the pulley during use.

[0011] For the transmission device, the technical solution of this application is:

[0012] A conveying device comprises a frame; a pulley and a conveyor belt tensioned outside the pulley are provided on the frame; the conveyor belt comprises a conveyor belt body; a group of strip protrusions spaced apart along the length direction of the conveyor belt body are provided on the outer circumference of the conveyor belt body; a group of annular belt teeth spaced apart along the width direction of the conveyor belt body are provided on the inner circumference of the conveyor belt body, and an annular groove is formed between two adjacent annular belt teeth; the annular belt teeth are meshed with the annular tooth grooves on the pulley for transmitting power; the conveyor belt body, the strip protrusions and the annular belt teeth are integrally cast and molded by polyurethane material; a skeleton is provided between the strip protrusions and the conveyor belt body.

When the conveyor device is used to convey disposable gloves, even if the conveyor device is tilted, the gloves can be stably placed on the conveyor belt; and the gloves can dissipate heat during the conveying process, thereby preventing the gloves from sticking after being transported to the packaging room and stacked together, thereby ensuring the quality of the gloves.

[0014] As an optimization, in the aforementioned conveying device, the skeleton includes an adhesive layer provided between the strip-shaped protrusion and the conveyor belt body; a tensile cord is embedded in the adhesive layer. Providing the tensile cord in the skeleton is beneficial to enhancing the tension and bending resistance of the conveyor belt and extending its service life; the design of the adhesive layer improves the peeling strength between the tensile cord and the conveyor belt body and the strip-shaped protrusion on both sides, thereby avoiding the tensile cord from falling off during the use of the conveyor belt. Furthermore, the tensile cord can be a Kevlar cord. The Kevlar cord has high strength and strong tensile resistance, thereby being able to improve the tensile strength of the conveyor belt and further ensure its service life.

[0015] As an optimization, in the aforementioned transmission device, the cross section of the annular belt teeth is V-shaped, that is, the ends of the annular belt teeth are thin and the roots are thick. In this case, the notch size of the annular groove will be relatively large, so that it is more convenient to insert the annular gear teeth on the pulley into the corresponding annular groove during assembly.
