Description

Technical Field

[0001] The utility model relates to the technical field of vending machines, in particular to a grab hook structure of a laundry ball vending machine. Background Art

[0002] Laundry balls are small transparent balls with laundry detergent wrapped in a water-soluble film. They are small in size and will automatically dissolve when thrown into the washing machine and stirred with water. The outer packaging film of the laundry ball is soft, smooth and very thin. It is a product that changes greatly due to environmental factors such as temperature and humidity. It has very poor acid resistance, and its shear tension and pressure resistance are very small. It will break if poked by a sharp object. The place where this kind of laundry ball vending machine is used is generally where there is a washing machine for rent nearby, and the environment is humid. At the same time, the profit of selling such products is generally not high. Based on this environmental background, we proposed a grab hook mechanism for the laundry ball vending machine.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 , 2 The utility model provides a technical solution: a hook structure for a laundry ball vending machine, comprising a chain 1 and a hook 3. Figure 2 Taking the perspective as a reference, the chain 1 rotates in a clockwise direction (the chain 1 is driven by an internal gear set, not shown in the figure), and the chain 1 and the grab hook 3 are connected and fixed by an "L"-shaped connecting piece 2. Holes are reserved at both ends of the connecting piece 2, and the grab hook 3 is installed on the connecting piece 2 by bolts.

[0028] In addition, the grab hook 3 includes a mounting connection portion 31, a limiting portion 33, a pressure bearing portion 34 and a warping portion 36. Figure 3 , 4 It can be seen that the various parts of the grab hook 3 are formed by bending, so the connecting portion 31, the limiting portion 33, the pressure-bearing portion 34 and the warping portion 36 are a whole, the installation connecting portion 31 is connected to the connecting member 2 by bolts, and a triangular protrusion 32 is fixedly installed on the upper part of the installation connecting portion 31 by bolts. The main function of the triangular protrusion 32 is to prevent two laundry balls 4 from being stacked on the grab hook 3 when the laundry ball 4 is obtained at one time. Therefore, the existence of the triangular protrusion 32 makes it possible for each grab hook 3 to carry only one laundry ball 4. Therefore, it is necessary to set the cross-section of the triangular protrusion 32 to be an equilateral triangle, and the tip is facing In addition, in order to protect the washing ball 4, the tip is also provided with a rounded corner, and the bottom end of the limiting portion 33 begins to fork to form two pressure-bearing portions 34, and the pressure-bearing portion 34 is the position for carrying the washing ball 4. Because of the fork, a hollow portion 35 is hollowed out in the middle of the pressure-bearing portion 34. The existence of the hollow portion 35 makes the bottom of the washing ball 4 sink a little bit, because the washing ball 4 is an outer layer of membrane with a structure of laundry liquid inside, which has good flexibility. The end of the pressure-bearing portion 34 is bent upward to form a warped edge portion 36, and the upward bending angle is 130°, which can effectively prevent the washing ball 4 from falling off the hook 3.

[0029] When in use, the movement trajectory of each grab hook 3 is as follows Figure 2 As shown, it includes four cycle actions of grabbing, waiting, releasing and idling. Specifically for each station:

[0030] Grabbing materials: Driven by the chain 1, the grab hook 3 passes through the bottom of the hopper (the hopper is not shown in the figure) and enters the hopper. When the washing ball 4 enters the pressure-bearing part 34 of the grab hook 3, the warped edge part 36 is a 130° inclined surface. Under the action of external force, the washing ball 4 will automatically move toward the limiting part 33 and adhere to the surface of the limiting part 33. Subsequently, the liquid in the soft washing ball 4 will sink a little bit in the hollow part 35 under the action of gravity, and the other parts of the bottom surface of the washing ball 4 will fit with the upper surface of the pressure-bearing part 34. At this time, the washing ball 4 is in a completely restrained state, and the grab hook 3 can grab the washing ball 4 and smoothly take it out of the material bin;

[0031] Waiting for materials: When the hook 3 grabs the washing ball 4, the chain 1 continues to rotate, and the hook 3 carries the washing ball 4 upward. During the upward movement, the washing ball will touch the sensing rod of the sensing device to trigger a sensing signal (not shown in the figure). The signal is fed back to the control center, and the control center issues an instruction to stop the motor. The hook 3 grabs the washing ball 4 and waits in the waiting area. The washing ball 4 is in a semi-restrained state.

[0032] Discharging: When the control center receives the selling signal, it sends a signal to start the motor, and the chain 1 with the grab hook 3 continues to move forward in a semicircle around the sprocket. At this time, the washing ball 4 is in an unconstrained state and is thrown forward to the pre-sale area under the action of gravity acceleration.

[0033] Idle running: After the grab hook 4 throws out the laundry ball, it continues to move forward, enters the material grabbing station, and enters the next cycle.
