Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to an anti-sticking transmission wheel for cable production. Background Art

[0002] During the production process of cables, traction machines, hoists, conveyors and other cable laying machines are required to pull the cables so that the cables can be moved within the processing equipment, which facilitates the processing of the cables. Due to the long length and heavy weight of the cables, a large number of transmission wheels need to be densely laid around the transmission path of the cables during the transmission process to provide support, position limiting and transmission effects for the cables. For example, Chinese patent CN213635514U discloses a cooling and transmission device for cable production, comprising an air-cooled box, a cooling box fixedly connected to one side of the air-cooled box, channels being provided on the side walls of the air-cooled box and the cooling box, a cable being provided inside one of the channels, a wire drawing machine being provided on one side of the air-cooled box, the wire drawing machine being engaged with the cable, and cooling mechanisms being provided inside the air-cooled box and the cooling box. This cable production cooling and transmission device uses a clamping block to quickly guide the cable through the cooling mechanism and then clamp it to the wire drawing machine. Cooling water inside the cooling box initially cools the cable, leaving the cable surface dry. During the cable cooling and transmission process, a large number of transmission wheels are densely arranged around the cable to ensure transmission stability. However, the transmission wheels fit tightly against the outer surface of the cable. After the cable moves rapidly, friction causes the contact area between the transmission wheels and the cable to heat up. This can cause cable surface materials, such as insulating rubber, to adhere to the transmission wheels, affecting transmission stability and product quality.

[0003] Therefore, it is necessary for technical personnel in this field to provide an anti-sticking transmission wheel for cable production, reduce the temperature of the contact part between the transmission wheel and the cable, prevent the insulating rubber from sticking to the transmission wheel due to high temperature, improve product quality, and ensure transmission stability. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-sticking transmission wheel for cable production, so as to solve the technical problem in the prior art that during the transmission and movement of the cable, the temperature of the part where the surface of the cable contacts the transmission wheel will rise rapidly, causing adhesion, affecting the transmission stability and product quality.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-sticking transmission wheel for cable production, including two symmetrically arranged brackets, multiple transmission wheels are symmetrically arranged around the symmetrical plane between the two brackets, the transmission wheels are rotatably arranged on the brackets around the axis and the circumferential side walls of the transmission wheels can abut the outer surface of the cable, multiple cylinders are installed on the brackets, the telescopic rods of the cylinders are fixedly connected to the mounting frame, the transmission wheels are rotatably connected to the mounting frame, and multiple injection pipes are also provided between the two brackets, the injection pipes are located below the transmission wheel and facing the circumferential side walls of the transmission wheel, and the injection pipes are connected to the high-pressure air pump.

[0006] Furthermore, a transmission wheel is respectively mounted on the telescopic rods of two cylinders, and the two cylinders controlling the movement of one transmission wheel form a cylinder group, and the multiple telescopic rods in the cylinder group are synchronously extended and retracted.

[0007] Furthermore, the cylinders are evenly arranged along the moving direction of the cable, and the cylinders are symmetrically arranged around the symmetry plane between the two brackets.

[0008] Furthermore, the transmission wheel is a cylindrical structure with large ends and a small middle, and the transmission wheel is made of stainless steel.

[0009] Furthermore, the air jet pipe is arranged at an angle, and the nozzle of the air jet pipe is directly facing the abutment point between the cable and the transmission wheel.

[0010] Furthermore, the air jet pipe is vertically arranged, and the nozzle of the air jet pipe faces the cable.

[0011] Furthermore, the air jet pipe is a plastic air blowing pipe, and the pipe body of the air jet pipe is flexible.

[0012] The beneficial effects of this utility model are as follows: the utility model directly sprays compressed air onto the contact area between the transmission wheel and the cable through the air jet pipe, thereby reducing the temperature of the contact area, thereby preventing the high temperature from causing the surface material of the cable, such as the insulating rubber, to peel off and adhere to the transmission wheel, thereby ensuring the stability and surface quality of the cable transmission. At the same time, the utility model also configures the transmission wheel to be movable. If the transmission wheel contacts the cable for too long, causing local overheating, the air cylinder can be adjusted to partially separate the transmission wheel from the outer surface of the cable, and then combined with the air jet pipe to achieve cooling.

[0018] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0019] See also Figure 1 The utility model provides an anti-sticking transmission wheel for cable production, including two symmetrically arranged brackets 10, and a plurality of transmission wheels 15 are symmetrically arranged around the symmetrical plane between the two brackets 10. The transmission wheel 15 is a cylindrical structure with large ends and a small middle. The transmission wheel 15 is rotatably arranged on the bracket 10 around an axis and the circumferential side wall of the transmission wheel 15 can abut the outer surface of the cable to achieve guided transmission of the cable.

[0020] Further, see Figure 2 、 Figure 3 、 Figure 4 A plurality of cylinders 11 are mounted on the bracket 10, and a mounting frame 12 is fixedly connected to the telescopic rod of the cylinder 11. The transmission wheel 15 is rotatably connected to the mounting frame 12 by a bearing. The transmission wheel 15 is made of metal, such as stainless steel, to ensure transmission while improving heat dissipation.

[0021] In this embodiment, a transmission wheel 15 is respectively installed on the telescopic rods of two cylinders 11. The two cylinders 11 that control the movement of one transmission wheel 15 form a cylinder group. The multiple telescopic rods in the cylinder group are synchronously extended and retracted, thereby ensuring the stability of the movement of the transmission wheel 15.

[0022] Furthermore, the cylinders 11 are evenly arranged along the moving direction of the cable, and at the same time, the cylinders 11 are symmetrically arranged around the symmetrical plane between the two brackets 10, so that the transmission wheels 15 located on the cylinders 11 can be evenly clamped on both sides of the cable, thereby ensuring the stability of the transmission.

[0023] The present invention realizes guided transmission of the cable by arranging two movable transmission wheels 15 on the cable. The symmetrically arranged transmission wheels 15 can ensure the stability of clamping. At the same time, the cylinder 11 can adjust the tightness of the clamping of the transmission wheels 15, thereby improving the use effect. When the transmission wheel 15 abuts against the cable for too long and causes local overheating, the cylinder 11 can be adjusted to make part of the transmission wheel 15 detach from the outer surface of the cable, thereby preventing the high temperature from causing the surface material of the cable, such as insulating rubber, to peel off and stick to the transmission wheel 15, thereby ensuring the stability and surface quality of the cable transmission.

[0024] It can be understood that the transmission wheel 15 is used to provide guidance and support for the transmission of the cable. When the transmission wheel 15 abuts the cable for too long and causes local overheating, the cylinder 11 is adjusted to make part of the transmission wheel 15 detach from the outer surface of the cable, while the other part of the transmission wheel 15 abuts the surface of the cable to maintain guidance and support to prevent the cable from detaching. After the transmission wheel 15 that has fallen off the cable is cooled, the cooled transmission wheel is re-adapted to the cable, and then the cylinder 11 is adjusted to make the other part of the transmission wheel 15 detach from the outer surface of the cable, thereby realizing intermittent replacement of the transmission wheel 15 while continuously supporting and transmitting the cable.

[0025] Please refer again Figure 4 A plurality of jet pipes 16 are further provided between the two brackets 10. The jet pipes 16 are located below the transmission wheel 15 and face the circumferential side wall of the transmission wheel 15. The jet pipes 16 are connected to a high-pressure air pump (not shown). When in use, compressed air is introduced into the jet pipes 16 through the high-pressure air pump, and then the compressed air is sprayed onto the circumferential surface of the transmission wheel 15 by the jet pipes 16 to cool the transmission wheel 15.

[0026] In this embodiment, the air jet pipe 16 is arranged at an angle, and the nozzle of the air jet pipe 16 is directly facing the contact point between the cable and the transmission wheel 15. Therefore, when the transmission wheel 15 is tightly attached to the outer surface of the cable, after the cable moves rapidly, the friction force will cause the temperature of the contact part between the transmission wheel 15 and the cable to rise. The compressed air is directly sprayed to the contact part through the air jet pipe 16 to reduce the temperature of the contact part, thereby preventing the high temperature from causing the surface material of the cable, such as insulating rubber, to peel off and stick to the transmission wheel 15, thereby ensuring the stability and surface quality of the cable transmission.

[0027] In another embodiment, the air jet pipe 16 is vertically arranged, and the nozzle of the air jet pipe 16 is facing the cable. By utilizing the circular outer contour of the cable, the compressed air ejected from the air jet pipe 16 can flow to both sides around the circumference of the cable, thereby achieving simultaneous cooling of the two transmission wheels 15 located on both sides of the cable, reducing the number of air jet pipes 16 and improving the use effect.

[0028] It can be understood that the air jet tube 16 is a common plastic air blowing tube on the market. The tube body of the air jet tube 16 is flexible and can be adjusted at multiple angles to ensure stability in use.

[0029] The specific operation method of the present invention is: using a traction device to movably set the cable between two brackets 10, starting the cylinder 11 to make multiple transmission wheels 15 abut against the cable, when the temperature of the contact part between the cable and the transmission wheel 15 is too high, starting the cylinder 11 to separate the transmission wheel 15 with the excessively high contact part from the cable, or opening the air injection pipe 16 to spray compressed air on the contact part between the transmission wheel 15 and the cable to achieve cooling.

[0030] The present invention uses an air jet 16 to directly spray compressed air onto the contact area between the transmission wheel 15 and the cable, reducing the temperature of the contact area. This prevents high temperatures from causing surface materials on the cable, such as insulating rubber, to peel off and adhere to the transmission wheel 15, thereby ensuring stable transmission and surface quality of the cable. Furthermore, the present invention also makes the transmission wheel 15 movable. If the transmission wheel 15 remains in contact with the cable for too long, causing local overheating, the air cylinder 11 can be adjusted to partially separate the transmission wheel 15 from the outer surface of the cable, thereby combining with the air jet 16 to achieve cooling.

[0031] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
