[0002] A washing machine assembly line is a production system specifically used to assemble the various components of a washing machine into a complete washing machine product in accordance with a predetermined process flow and sequence. It usually includes a series of workstations and equipment, with each workstation responsible for completing a specific assembly task. On this production line, components are transported to the corresponding workstations via belt conveyors.

[0003] Due to the large variations in size of washing machine assembly parts, the conveyor belt width is typically between 80cm and 100cm. Small parts assembly stations often require workers to stretch their arms to retrieve them because the parts are delivered far from their workstations. This long work schedule severely drains workers' energy, leaving them with limited practicality. Therefore, to address these issues, we propose a belt conveyor for washing machine assembly lines to address them. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a belt conveyor for a washing machine assembly production line, comprising a U-shaped frame 1, wherein rollers 11 are symmetrically rotatably connected between the front and rear inner walls of the U-shaped frame 1, a conveyor belt 12 is transmission-connected between the outer surfaces of the two rollers 11, a guide mechanism 3 is provided near the upper portion of the front and rear inner walls of the U-shaped frame 1, and a tensioning mechanism is provided near the lower portion between the inner walls of the U-shaped frame 1.

[0023] The two guide mechanisms 3 each include an H-shaped frame 301, a first mounting groove 302 is provided inside the H-shaped frame 301, a plurality of first rotating rollers 303 are equidistantly connected to the inner top and inner bottom of the first mounting groove 302, the outer surfaces of the two H-shaped frames 301 on opposite sides are fixedly connected to a connecting shell 308, the outer surfaces of the two connecting shells 308 on opposite sides are rotatably connected to an adjusting screw rod 310 near the middle, the outer surfaces of the two connecting shells 308 on opposite sides are symmetrically fixedly connected to guide rods 309 on both sides of the adjusting screw rod 310, and the guide rods The outer surface of 309 slides through the inner wall of the U-shaped frame 1 and extends to the outside. The outer surface of the adjusting screw rod 310 is threaded through the inner wall of the U-shaped frame 1 and extends to the outside. Both ends of the H-shaped frame 301 are rotatably connected to the oblique frame 304. A second mounting groove 305 is provided on the outer surface of one side of the oblique frame 304. A second rotating roller 306 is rotatably connected between the inner top and the inner bottom of the second mounting groove 305. The outer surface of the second rotating roller 306 is in contact with the inner wall of the U-shaped frame 1. A tie rod 307 is connected between the outer surfaces of the oblique frame 304 and the H-shaped frame 301.

[0024] The front surface of the U-shaped frame 1 is fixedly connected to a motor frame 13, and a servo motor 14 is installed on the top of the motor frame 13. The output end of the servo motor 14 is fixedly connected to the front end of one of the rollers 11. A plurality of support rollers 2 are equidistantly connected to the front and rear inner walls of the U-shaped frame 1, and the outer surface of the support roller 2 is in contact with the inner top of the conveyor belt 12.

[0025] During use, the servo motor 14 is started by the external PLC controller to drive one of the rollers 11 to rotate, and the other roller 11 and the conveyor belt 12 start to move under the action of friction, thereby conveying the washing machine accessories to the assembly station; according to the different order of the stations, the station personnel who assemble the small accessories of the washing machine can rotate the adjusting screw 310 at the opposite position. At this time, the adjusting screw 310 will push the connecting shell 308 and the H-shaped frame 301 to move toward the middle direction of the conveyor belt 12 under the action of the thread. At this time, the inclined frames 304 on both sides of the H-shaped frame 301 will be retracted inwardly under the action of the tension rod 307 until the second rotating roller 306 is in contact with the inner wall of the U-shaped frame 1. At this time, the inclined frames 304 and H A bent trapezoid is formed between the frame 301 and the inner wall of the U-frame 1; when the washing machine assembly on the conveyor belt 12 passes through this area, it will slide down to the side of the H-frame 301 close to the employee under the action of the inclined frame 304, and when it contacts the first rotating roller 303 in the first mounting groove 302 inside the H-frame 301, it plays a role in converting the sliding friction between the H-frame 301 and the washing machine assembly into rolling friction, so that it can be smoothly transported to the work station for assembly; this design can adjust the distance of the H-frame 301 so that the small washing machine accessories can be transported close to the work station when they are transported to the work station, which is convenient for employees to pick up and assemble, and can save a lot of physical strength under long-term working conditions, and is highly practical.

[0026] The support roller 2 designed between the conveyor belts 12 is mainly used to support the conveying surface of the conveyor belt 12, ensuring stability when conveying heavier accessories in the washing machine. When one end of the inclined frame 304 slides closely against the inner wall of the U-shaped frame 1 during the movement of the H-shaped frame 301, the second rotating roller 306 converts sliding friction into rolling friction, reducing friction damage and increasing the service life of the equipment. The guide rod 309 guides the H-shaped frame 301, allowing it to move stably in a straight line.

[0027] The tensioning mechanism 4 includes a mounting plate 401, which is fixedly connected between the front and rear inner walls of the U-shaped frame 1. An electric push rod 402 is fixedly installed on the outer surface of one side of the mounting plate 401. The telescopic end of the electric push rod 402 is fixedly connected to a rotating seat 403. A tensioning roller 404 is rotatably connected to a position near the top between the inner walls of the rotating seat 403. The outer surface of the tensioning roller 404 is in contact with the outer surface of the conveyor belt 12.

[0028] When the conveyor belt 12 becomes loose due to long-term use, the electric push rod 402 on the mounting plate 401 is started to push the rotating seat 403 upward. At this time, the rotating tensioning roller 404 on the rotating seat 403 will squeeze the position below the conveyor belt 12 upward, so that the conveying surface above the conveyor belt 12 remains taut, ensuring the stability of the conveying washing machine assembly and better use effect.
