[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 6 As shown, this utility model provides a linen lifting and turning feeding machine for the laundry industry, including a base plate 1, a bracket 2 fixedly connected to the upper surface of the base plate 1, a rotating shaft 3 rotatably connected inside the bracket 2, a gear 4 fixedly installed on the surface of the rotating shaft 3, a chain 5 drivingly connecting the upper and lower gears 4, a first bolt 6 fixedly connected inside the chain 5, a fixing plate 7 fixedly connected to the surface of the first bolt 6, a turning structure provided at the front of the fixing plate 7, a motor 26 fixedly connected to the upper right surface of the base plate 1, and the output shaft of the motor 26 fixedly connected to the right end of the lower rotating shaft 3.
[0023] When the staff puts the linens into the collection box 16, they start the motor 26. The rotation of the output shaft of the motor 26 drives the rotating shaft 3 inside the bracket 2 to rotate, which in turn drives the gear 4 to rotate. Since the upper and lower gears 4 are connected by a chain 5, the chain 5 is driven to move. At the same time, the fixing plate 7 is fixed to the lower part of the chain 5 by the first bolt 6, which in turn drives the spiral plate 8 to rise with the drive of the chain 5, thereby driving the collection box 16 set at the front end of the first bolt 6 to rise and fall.
[0024] The front of the fixed plate 7 is fixedly connected to a U-shaped plate 8. The upper end of the U-shaped plate 8 is rotatably connected to a hinge shaft 9. The surface of the hinge shaft 9 is fixedly connected to a flip plate 10. Limiting posts 11 are fixedly connected to the left and right sides of the flip plate 10. The rear of the flip plate 10 and the hinge shaft 9 are fixedly connected to a fixed block 12. The interior of the fixed block 12 is rotatably connected to a limiting wheel 13.
[0025] As the fixed plate 7 rises with the chain 5, and the fixed block 12 connected to the upper part of the flip plate 10 provides a position for the limiting wheel 13, the limiting wheel 13 slides inside the slide groove 24. When the upper limiting wheel 13 is located at the upper rear end of the bracket 2, the upper part of the flip plate 10 no longer rotates with the transmission of the chain 5. However, at this time, the limiting wheel 13 installed at the rear of the loop plate 8 still moves upward. Since the flip plate 10 and the loop plate 8 are hinged through the hinge shaft 9, the flip plate 10 is driven to flip, thereby driving the collection box 16 installed at the front of the loop plate 8 to rotate and dump the linens into the guide channel 19.
[0026] The front of the flip plate 10 is provided with a slide groove 14, and a second bolt 15 is movably connected inside the slide groove 14. A collection box 16 is fixedly connected to the front of the second bolt 15. A weighing platform 17 is provided at the lower part of the collection box 16 and is placed on the upper surface of the base plate 1.
[0027] With the transmission of the chain 5 via the fixed plate 7, when the lower limiting wheel 13 is located at the lower part of the slide 24, the collection box 16 will reach the upper surface of the weighing platform 17 first. At this time, the second bolt 15 slides upward along the inside of the slide 14, so that the flipping plate 10 will not exert downward pressure on the collection box 16. Finally, the weight of the linen inside the collection box 16 is equal to the weight weighed by the weighing platform 17 minus the weight of the collection box 16 and the second bolt 15 themselves.
[0028] The upper surface of the base plate 1 is fixedly connected to a first bracket 18, the inner side of the first bracket 18 is fixedly connected to a flow channel 19, the lower part of the flow channel 19 is fixedly connected to a second bracket 20, and the lower surface of the second bracket 20 is fixedly welded to the upper surface of the base plate 1.
[0029] The first support 18 and the second support 20 provide support for the flow channel 19. The first support 18 and the second support 20 are triangular, so the support effect is good. At the same time, the flow channel 19 guides the linens into the washing machine.
[0030] The rear part of the flip plate 10 is fixedly connected to a first tension spring connecting block 21, the lower upper surface of the spiral plate 8 is fixedly connected to a second tension spring connecting block 22, and a tension spring 23 is fixedly connected between the first tension spring connecting block 21 and the second tension spring connecting block 22.
[0031] With the tension spring 23 initially in a slightly stretched state, the flip plate 10 and the return plate 8 are stretched through the first tension spring connecting block 21 and the second tension spring connecting block 22, so that the collection box 16 will not shake when it is raised and lowered, ensuring the stability of the raising and lowering. However, the limiting post 11 contacts the front surface of the bracket 2 to prevent the collection box 16 from impacting the chain 5 when it is flipped and lowered.
[0032] The bracket 2 has a groove 24 on its inner side, and the inside of the groove 24 is movably connected to the outer end of the limiting wheel 13.
[0033] The cooperation between the slide groove 24 and the limiting wheel 13 ensures that the flip plate 10 and the spiral plate 8 will not shake during lifting and flipping, and provides conditions for the early flipping of the flip plate 10.
[0034] The upper surface of the base plate 1 is fixedly connected to the control box 25, which is electrically connected to the motor 26 and the weighing platform 17.
[0035] The control box 25 controls the start of the motor 26 and the measurement of the weighing platform 17, and retains the weighing value of the weighing platform 17.
[0036] Working principle and usage process of this utility model:
[0037] When the staff puts the linens into the collection box 16, they start the motor 26. The rotation of the output shaft of the motor 26 drives the rotating shaft 3 inside the bracket 2 to rotate, which in turn drives the gear 4 to rotate. Since the upper and lower gears 4 are connected by a chain 5, the chain 5 is driven to move. At the same time, the fixing plate 7 is fixed to the lower part of the chain 5 by the first bolt 6, which in turn drives the spiral plate 8 to rise with the drive of the chain 5, thereby driving the collection box 16 set at the front end of the first bolt 6 to rise and fall.
[0038] As the fixed plate 7 rises with the chain 5, and the fixed block 12 connected to the upper part of the flip plate 10 provides a position for the limiting wheel 13, the limiting wheel 13 slides inside the slide groove 24. When the upper limiting wheel 13 is located at the upper rear end of the bracket 2, the upper part of the flip plate 10 no longer rotates with the transmission of the chain 5. However, at this time, the limiting wheel 13 installed at the rear of the loop plate 8 still moves upward. Since the flip plate 10 and the loop plate 8 are hinged through the hinge shaft 9, the flip plate 10 is driven to flip, thereby driving the collection box 16 installed at the front of the loop plate 8 to rotate and dump the linens into the guide channel 19.
[0039] With the transmission of the chain 5 via the fixed plate 7, when the lower limiting wheel 13 is located at the lower part of the slide 24, the collection box 16 will reach the upper surface of the weighing platform 17 first. At this time, the second bolt 15 slides upward along the inside of the slide 14, so that the flipping plate 10 will not exert downward pressure on the collection box 16. Finally, the weight of the linen inside the collection box 16 is equal to the weight weighed by the weighing platform 17 minus the weight of the collection box 16 and the second bolt 15 themselves.
[0040] The first support 18 and the second support 20 provide support for the flow channel 19. The first support 18 and the second support 20 are triangular, so the support effect is good. At the same time, the flow channel 19 guides the linens into the washing machine.
[0041] With the tension spring 23 initially in a slightly stretched state, the flip plate 10 and the return plate 8 are stretched through the first tension spring connecting block 21 and the second tension spring connecting block 22, so that the collection box 16 will not shake when it is raised and lowered, ensuring the stability of the raising and lowering. However, the limiting post 11 contacts the front surface of the bracket 2 to prevent the collection box 16 from impacting the chain 5 when it is flipped and lowered.
[0042] The cooperation between the slide groove 24 and the limiting wheel 13 ensures that the flip plate 10 and the spiral plate 8 will not shake during lifting and flipping, and provides conditions for the early flipping of the flip plate 10.
[0043] The control box 25 controls the start of the motor 26 and the measurement of the weighing platform 17, and retains the weighing value of the weighing platform 17.
