DETAILED DESCRIPTION
[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0022] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.
[0023] Reference Figures 1 to 7 The device shown is a device for horizontally flipping and folding a bed sheet, comprising a frame 1, a pressing mechanism 2, a left-side folding mechanism 3, a right-side folding mechanism 4 and a conveyor belt 5. The conveyor belt 5 is fixedly mounted on the frame 1, and the conveyor belt 5 is used to horizontally convey the bed sheet. The pressing mechanism 2 is located directly above the conveyor belt 5, and the pressing mechanism 2 is fixedly connected to the frame 1. The pressing mechanism 2 is used to press the middle area of the bed sheet conveyed directly below. The left-side folding mechanism 3 is located on the left side of the conveyor belt 5, and the left-side folding mechanism 3 is fixedly mounted on the frame 1. The left-side folding mechanism 3 is used to fold the left-side area of the bed sheet toward the middle. The right-side folding mechanism 4 is located on the right side of the conveyor belt 5, and the left-side folding mechanism 3 is fixedly mounted on the frame 1. The right-side folding mechanism 4 is used to fold the right-side area of the bed sheet toward the middle. The specific working method is as follows: first, the middle part of the bed sheet located at the bottom is pressed by the pressing mechanism 2, so that the middle part of the bed sheet cannot move, then the left side area of the bed sheet not pressed by the pressing mechanism 2 is folded toward the middle part by the left folding mechanism 3, and then the right side area of the bed sheet not pressed by the pressing mechanism 2 is folded toward the middle part by the right folding mechanism 4, so that the bed sheet can be folded. Then, the pressing mechanism 2 is slightly lifted upwards, and the bed sheet is no longer pressed, and then the conveyor belt 5 transmits the folded bed sheet, so that the bed sheet can be drawn out from the horizontal pressing part of the pressing mechanism 2 and enter the next process.
[0024] It also includes an adjusting mechanism 6, a sealing plate 1 7 and a sealing plate 2 8. The left folding mechanism 3 is fixedly installed on the displacement seat of the adjusting mechanism 6. The adjusting mechanism 6 is used to adjust the horizontal position of the left folding mechanism 3, so that it can be suitable for sheets of various specifications. The sealing plate 1 7 is located on the side of the left folding mechanism 3 close to the right folding mechanism 4, and the sealing plate 2 8 is located on the other side of the left folding mechanism 3. The sealing plate 1 7 and the sealing plate 2 8 are both fixedly installed on the adjusting mechanism 6, and the sealing plate 1 7 is inserted in the middle of the conveyor belt 5. Through this structural arrangement, the gap opened by adjusting the position of the left folding mechanism 3 can be covered by the sealing plate 1 7 and the sealing plate 2 8 to prevent the edge of the sheet from falling into the gap.
[0025] The left folding mechanism 3 includes a push plate 3a, a lifting mechanism 3b and a horizontal displacement mechanism 3c. The push plate 3a is fixedly mounted on the lifting end of the lifting mechanism 3b. The lifting mechanism 3b is used to lift the push plate 3a vertically upward. The lifting mechanism 3b is fixedly mounted on the horizontal pushing end of the horizontal displacement mechanism 3c. The horizontal displacement mechanism 3c is used to drive the push plate 3a to move horizontally toward the middle of the bed sheet. The push plate 3a is fixedly mounted on the adjustment mechanism 6. When the bed sheet is conveyed, the left side of the bed sheet will fall above the push plate 3a, and then the bed sheet will be lifted upward by the push plate 3a, and at the same time, the horizontal displacement mechanism 3c pushes the push plate 3a horizontally, so that the push plate 3a pushes the bed sheet horizontally. The left side of the bed sheet will move toward the middle, and the bed sheet will be blocked by the edge of the pressing mechanism 2 during the movement, and the bed sheet will gradually slide off the push plate 3a, so that the bed sheet can be folded. Among them, the structure of the right folding mechanism 4 is the same as that of the left folding mechanism 3 and will not be described below. The difference is that the left folding mechanism 3 is installed on the adjustment mechanism 6, while the right folding mechanism 4 is installed on the frame 1.
[0026] The adjusting mechanism 6 includes a slide rail 1 6a, a slide seat 1 6b, a slide rail 2 6c, a slide seat 2 6d and an electric slide table 6e. The sealing plate 1 7 and the sealing plate 2 8 are fixedly connected to the top of the slide seat 2 6d through the connecting frame 6f. The slide seat 2 6d is slidably connected to the slide rail 2 6c. The slide rail 2 6c is fixedly installed on the frame 1. The slide seat 1 6b is fixedly installed on the top of the connecting frame 6f. The slide rail 1 6a is fixedly installed on the frame 1. The slide rail 1 6a is slidably connected to the slide seat 1 6b. The connecting frame 6f is fixedly connected to the displacement slide seat of the electric slide 6e. The electric slide 6e is fixedly mounted on the frame body 1. The horizontal displacement mechanism 3c is fixedly mounted on the connecting frame 6f. By controlling the electric slide 6e to work, the electric slide 6e will push the connecting frame 6f to move horizontally, so that the connecting frame 6f can drive the sealing plate 1 7, the push plate 3a and the sealing plate 2 8 to adjust their positions at the same time.
[0027] The pressing mechanism 2 includes a pressing cylinder 2a, a connecting rod 2b and two pressing rods 2c. The pressing cylinder 2a is fixedly mounted on the frame 1, the connecting rod 2b is fixedly mounted on the downward push end of the pressing cylinder 2a, and the pressing rods 2c are fixedly mounted on both sides of the connecting rod 2b. By controlling the pressing cylinder 2a to press downward, the two pressing rods 2c press the bed sheet, and the area between the two pressing rods 2c is the middle area of the bed sheet pressed by the pressing mechanism 2 described above. The pressing rod 2c can be shaft-shaped or flat.
[0028] The lifting mechanism 3b includes a lifting cylinder 3b1, a guide seat 3b3 and two guide pillars 3b2. The guide seat 3b3 is fixedly mounted on the horizontal pushing end of the horizontal displacement mechanism 3c. Both guide pillars 3b2 are slidably connected to the guide seat 3b3. The top of the guide pillar 3b2 is fixedly connected to the push plate 3a. 3b is fixedly mounted on the horizontal pushing end of the horizontal displacement mechanism 3c. The output end of 3b is fixedly connected to the push plate 3a. By controlling 3b to work, 3b will lift the push plate 3a vertically upward. The guide pillars 3b2 and the guide seat 3b3 are used to guide the vertical movement of the push plate 3a.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
