[0004] The above - mentioned patent records a narrow - belt sorting machine. The conveyor belt of this narrow - belt sorting machine is driven and operated by a chain as a whole. During the actual operation process, it is necessary to lubricate the drive chain of the conveyor belt regularly. If the lubrication and maintenance are lacking, the running resistance of the conveyor belt will increase, affecting the conveying efficiency, increasing energy consumption. The lubrication work of the conveyor belt is usually carried out manually, and the degree of intelligence is relatively low. Therefore, we propose a belt conveying structure of a narrow - belt sorting machine to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further explain the technical solution of this utility model, the following will be elaborated in detail through specific embodiments.

[0022] Please refer to Figure 1 , this utility model provides a belt conveying structure of a narrow-band sorting machine, including a frame 1, a belt roller 2, a transmission chain 3, a motor 4, a conveyor belt 5, and an automatic lubrication device 6. A row of belt rollers 2 are rotatably installed inside the frame 1, and the belt rollers 2 are connected by a transmission chain 3 for transmission. A motor 4 is installed at the rear end of the side of the frame 1, and the output end of the motor 4 is connected to the end roller shaft of the belt roller 2. A conveyor belt 5 is sleeved outside the belt roller 2, and an automatic lubrication device 6 is arranged at the bottom of the transmission chain 3.

[0023] Please refer to Figures 2-4, the present utility model provides a belt conveying structure of a narrow-band sorting machine. The automatic lubrication device 6 includes a bracket 61, a lubricating gear 62, a lubricating cover 63, a hose 64, a liquid storage tank 65, a tank opening 66, a two-way pump 67, a controller 68, and a lubricant 69. The front end of the side of the frame 1 is bolted with a bracket 61. In the middle of the inner side of the bracket 61, a lubricating gear 62 is rotatably installed, and the lubricating gear 62 meshes with the bottom of the transmission chain 3 for transmission. In the middle of the inner side of the bracket 61, a lubricating cover 63 is screwed and installed. The lubricating cover 63 covers the lower half surface of the lubricating gear 62 but there is no direct contact between them. The bottom end opening of the lubricating cover 63 is communicated with a hose 64. On the horizontal plate at the bottom of the inner side of the bracket 61, a liquid storage tank 65 is installed. The end of the hose 64 is communicated and installed to the inner bottom surface of the liquid storage tank 65. On the front inclined surface of the liquid storage tank 65, a tank opening 66 is provided, and the lubricant 69 can be replenished into the liquid storage tank 65 through the tank opening 66. In the middle of the hose 64, a two-way pump 67 is communicated and installed, and the two-way pump 67 is screwed and installed on the inner side of the bracket 61. In the middle of the outer side of the bracket 61, a controller 68 is installed. The two-way pump 67 is connected to the controller 68 through a wire to establish a control connection. The liquid storage tank 65 is filled with the lubricant 69. The two-way pump 67 can pump the lubricant 69 into the lubricating cover 63 through the hose 64, so that the lower half of the lubricating gear 62 is immersed in the lubricant 69. When the transmission chain 3 operates, the rotating lubricating gear 62 can apply the lubricant 69 to the surface of the passing transmission chain 3, thereby realizing the lubrication and oiling operation of the whole transmission chain 3.

[0024] Further explanation, the longitudinal section shape of the lubricating cover 63 is semi-circular, so that the lubricant 69 in the lubricating cover 63 can be better pumped out by the hose 64 and is not easy to remain.

[0025] Further explanation, an air hole is provided at the top of the liquid storage tank 65 to maintain the air pressure balance inside the liquid storage tank 65 and ensure the normal operation of the two-way pump 67.

[0026] Further explanation, a counter 610 is installed on the side of the lubricating cover 63. The input shaft of the counter 610 is connected to the axle of the lubricating gear 62. The counter 610 can count and measure the number of rotations of the transmission chain 3 through the lubricating gear 62. The counter 610 is connected to the controller 68 through a wire to establish a data connection, so that the controller 68 can set the trigger threshold of lubrication and oiling according to the number of rotations of the transmission chain 3, and can more accurately control the timing of lubrication and maintenance.

[0027] Further explanation, a liquid level sensor 611 is installed on the side wall of the lubricating cover 63. The liquid level sensor 611 is connected to the controller 68 through a wire to establish a data connection, so that the controller 68 can accurately control the liquid volume of the lubricant 69 inside the lubricating cover 63 through the liquid level sensor 611.

[0028] Furthermore, when the automatic lubrication device 6 is in the standby state, the lubricant 69 inside the lubrication cover 63 will be completely pumped out by the two-way pump 67 into the liquid storage tank 65 for storage, avoiding the problem of deterioration caused by the long-term exposure of the lubricant 69.

[0029] The working principle is as follows:

[0030] First, before use, first place the frame 1 on a flat surface to ensure the stable operation of the equipment without shaking. Then, power on the motor 4 and the automatic lubrication device 6 to meet their power requirements. Subsequently, open the tank opening 66 and supplement an adequate amount of lubricant 69 into the liquid storage tank 65 through it. Finally, close the tank opening 66.

[0031] Second, during use, the motor 4 drives the single belt roller 2 to rotate, and the belt rollers 2 are synchronously driven through the transmission chain 3, thereby driving the conveyor belt 5 to operate. With the help of the conveyor belt 5, the conveying operation of the objects can be realized.

[0032] Third, while the transmission chain 3 is running, it will also drive the rotation of the lubrication gear 62 at its bottom. By connecting a counter 610 to the side of the lubrication gear 62, the counter 610 can count and measure the number of rotations of the transmission chain 3 through the lubrication gear 62, enabling the controller 68 to set the trigger threshold for lubrication and oiling according to the number of rotations of the transmission chain 3. For example, when the transmission chain 3 rotates 8000 circles, the controller 68 is triggered to perform the lubrication and oiling operation, which can more accurately control the timing of lubrication and maintenance.

[0033] Fourth, by setting the automatic lubrication device 6, during use, when the number of rotations of the transmission chain 3 reaches the trigger threshold set by the controller 68, the controller 68 starts the two-way pump 67. At this time, the two-way pump 67 pumps the lubricant 69 stored inside the liquid storage tank 65 into the lubrication cover 63 through the hose 64. The controller 68 can accurately control the liquid volume of the lubricant 69 inside the lubrication cover 63 through the liquid level sensor 611, immersing the lower half of the lubrication gear 62 in the lubricant 69. During the operation of the transmission chain 3, the driven rotating lubrication gear 62 can continuously apply the lubricant 69 to the surface of the passing transmission chain 3, thereby realizing the lubrication and oiling operation of the entire transmission chain 3, enabling automatic lubrication operation, reducing manual operation, and making the sorting line more intelligent.

[0034] Fifth, after completing a lubrication operation, the controller 68 starts the reverse rotation of the two-way pump 67, so that the two-way pump 67 pumps out and discharges the lubricant 69 inside the lubrication cover 63 through the hose 64 and pumps it back into the liquid storage tank 65 for storage, providing a better storage environment for the lubricant 69 to extend the service life of the lubricant 69.

[0035] The above are only the preferred examples of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
