[0036] An article replacement device, comprising a housing 5, a lifting device, a weighing platform 4, a support frame 3, an exchange box 2 and a controller;

[0037] The housing 5 encloses the support frame 3 to form a cabinet, the lower portion of the cabinet is provided with an item outlet 6, the upper portion of the cabinet is provided with an item inlet 7, and the item inlet 7 is provided with a sensor 1 for sensing whether there is an item on the plane where the item inlet 7 is located;

[0038] The exchange box 2 is installed at the lower end of the support frame 3. The exchange box 2 is used to store the target replacement object. The discharge port 24 of the exchange box 2 is connected to the item outlet 6.

[0039] The lifting device is installed above the exchange box 2, and the lifting device includes a lifting platform 12 that can move up and down. The top surface of the lifting platform 12 is installed with the weighing platform 4, and the top surface of the weighing platform 4 is the loading surface;

[0040] The space formed by the plane where the article entrance 7 is located, the loading surface and the housing 5 is a storage space 32, and the storage space 32 is used to store articles put in through the article entrance 7;

[0041] The lifting device, the weighing platform 4, the sensor 1 and the exchange box 2 are respectively communicated with the controller; the controller is used to receive the sensing information of the sensor 1, and is also used to receive the weighing information of the weighing platform 4, and is also used to control the lifting and lowering of the lifting device, and is also used to control the switch of the discharge port 24 of the exchange box 2 according to the weighing information.

[0042] Specifically, if Figure 1-5 As shown, the support frame 3 serves as the supporting structure of the entire device. Its external shape can be rectangular or square. In this embodiment, the support frame 3 is rectangular in shape and is enclosed by a housing 5 to form a cabinet. In actual use, this cabinet can be a closed cabinet. The cabinet can be divided into two parts, upper and lower. The lower part of the cabinet is equipped with an exchange box 2 and an item outlet 6. The exchange box 2 contains items that users can exchange for, called target exchange items. The upper part of the cabinet has an item inlet 7, through which users can insert exchange items. The exchange items land on the weighing platform 4 inside the support frame 3. The space formed by the plane of the item inlet 7, the loading surface, and the housing 5 is the storage space 32 for storing the exchange items. It is worth noting that the exchange items can be recyclable garbage or resources, and the target exchange items can be practical items in daily life. Therefore, the exchange items may contain fragile items, such as glass bottles. Therefore, the weighing platform 4 in this embodiment is initially positioned close to the item inlet 7 to prevent the glass bottles from breaking when reaching the weighing platform 4. During specific use, the designated exchange object is put into the item entrance 7. When the exchange objects on the weighing platform 4 increase, the controller receives the weighing information of the weighing platform 4. According to the pre-set ratio, for example, 1g of exchange object is exchanged for 1g of target exchange object, the controller controls the discharge port 24 of the exchange box 2 to open, and the target exchange object enters the item outlet 6 from the discharge port 24; after multiple item exchanges, the items in the storage space 32 gradually accumulate. When the sensor senses that there are items on the plane where the item entrance 7 is located, in order to free up the storage space 32, the sensor sends a sensing information, and the controller controls the lifting device to move the position of the weighing platform 4 to the bottom end of the support frame 3, and the weighing platform 4 moves downward accordingly to expand the storage space 32 to prevent the exchange objects from blocking the item entrance 7.

[0043] This solution uses the weighing platform 4 to sense the weight change of the exchange object and control the exchange with the target replacement object in the exchange box 2, reducing manual intervention and the complexity of operation. The lifting device can effectively expand or reduce the storage space 32, improving the adaptability of the device when space is insufficient; the equipment structure of this solution is simple. Compared with complex automated equipment, the components and structural design of this device are relatively simple, with lower production cost and assembly cost.

[0044] Furthermore, the support frame 3 is further provided with a top limit member 33 and a bottom limit member 34 , and the top limit member 33 and the bottom limit member 34 are respectively used to limit the top limit position and the bottom limit position of the movement of the lifting platform 12 .

[0045] Specifically, the top limit member 33 and the bottom limit member 34 ensure that the lifting platform 12 does not exceed a predetermined range during movement, preventing the lifting platform 12 from damaging other objects in the device due to excessive movement, and indirectly extending the service life of the device.

[0046] Preferably, the lifting device also includes a guide rod 11 and a belt 13, the lifting platform 12 is slidably mounted on the guide rod 11, the lifting platform 12 is installed with a belt clamping member 121, the guide rod 11 and the belt 13 are both vertically arranged, and when the belt 13 is transmitted, the lifting platform 12 is driven to slide up and down through the belt clamping member 121.

[0047] Specifically, the lifting device also includes a guide rod 11 and a belt 13. A weighing platform 4 is placed on the lifting platform 12. When the weighing platform 4 needs to be moved, the belt 13 is driven by an external force. The belt clamping member 121 clamps the belt 13 to move the lifting platform 12 along the installation direction of the guide rod 11, thereby expanding the storage space 32 when there is insufficient space, and reducing the distance between the weighing platform 4 and the item entrance 7 when there is sufficient space, thereby preventing damage to the exchanged items.

[0048] The design of the belt clamping member 121 helps to maintain the stability of the lifting platform 12 when sliding up and down, and can help prevent the lifting platform 12 from unnecessary shaking or deviation during the lifting process.

[0049] Furthermore, the number of the belts 13 is an even number, and the belts 13 are symmetrically and vertically arranged on both sides of the lifting platform 12. A driving motor 35 is provided at the top of the support frame 3, and a coupling 36 is provided at the output end of the driving motor 35.

[0050] Each of the belts 13 is provided with two corresponding pulleys 131 , and the driving motor 35 drives the pulleys 131 through the coupling 36 to drive the belts 13 .

[0051] Specifically, a drive motor 35 is provided at the top of the support frame 3. In this embodiment, a coupling 36 is used to connect the output end of the drive motor 35 and the pulley 131, so that the rotational motion generated by the motor can be effectively transmitted to the pulley 131. The coupling 36 transmits the torque of the motor to the rotating shaft of the pulley 131. The symmetrical pulleys 131 can rotate synchronously so that the lifting platform 12 can be lifted and lowered smoothly. The drive motor 35 set at the top can avoid occupying additional space at the bottom or side of the equipment, making the overall layout more compact.

[0052] Preferably, the number of the guide rods 11 is 4;

[0053] The four guide rods 11 are symmetrically and vertically arranged on both sides of the lifting platform 12;

[0054] The support frame 3 is provided with a polished rod support 37 for fixing the guide rod 11 , and both ends of the guide rod 11 are provided with the polished rod support 37 .

[0055] Specifically, the design of the light rod support 37 ensures the stable installation of the guide rod 11. The four guide rods 11 are symmetrically arranged on both sides of the lifting platform 12, which helps to evenly distribute the weight of the lifting platform 12 and reduce the tilting or shaking of the lifting platform 12 during the lifting process, thereby improving the overall stability. The four guide rods 11 effectively share the pressure of the platform and the load, improve the overall carrying capacity, and avoid deformation or damage of a single light rod due to overload.

[0056] Preferably, the exchange box 2 includes a pushing device 21, and the output end of the pushing device 21 is connected to a pushing plate 23;

[0057] A rotatable material baffle 22 is provided at the bottom of the exchange box 2. The pushing plate 23 is pushed by the output end of the pushing device 21 to rotate the material baffle 22 relative to the exchange box 2, and the discharge port 24 is formed at the bottom of the exchange box 2.

[0058] Specifically, if Figure 5 As shown, during item exchange, a pusher 21 on the surface of the exchange box 2 drives a push plate 23 to move. Because the push plate 23 is located on one side of the material baffle 22, its movement causes the material baffle 22 to rotate, forming an open discharge port 24 between the bottom of the exchange box 2 and the material baffle 22. The target exchanged item is removed from the discharge port 24. The pusher 21 automatically drives the push plate 23, thereby controlling the opening and closing of the material baffle 22, achieving automated adjustment of the discharge port 24. The size of the discharge port 24 can be changed according to the load-bearing changes of the weighing platform 4, reducing reliance on manual operation.

[0059] Furthermore, a drop area 25 is provided at the article outlet 6, and the drop area 25 is provided below the exchange box 2;

[0060] The discharge port 24 is connected to the blanking area 25 , and the target replacement object in the exchange box 2 enters the blanking area 25 through the discharge port 24 .

[0061] Specifically, by setting the drop-off area 25 below the exchange box 2, it can be ensured that the target replacement object falls accurately into the designated area when discharged, and the target replacement object will not fall outside the device. The target replacement object can be protected from external influences for a short time. For example, if there is water on the ground or it is raining outside, the target replacement object will be immediately soaked by water, so the setting of the drop-off area 25 helps to reduce the possibility of damage to the items.

[0062] Preferably, the article inlet 7 is a long strip opening, the height of the long strip opening is 2CM-3CM, the length direction of the long strip opening is parallel to the horizontal direction, and the article inlet 7 is used to put cardboard.

[0063] By limiting the size of the article inlet 7, it is ensured that only cardboard can be put in.

[0064] Furthermore, the exchange box 2 is used to store pet food, and a door for taking in and out is provided on the back of the cabinet.

[0065] By self-service recycling of used cardboard, an equal amount can be exchanged for pet food. The access door is set to open the item replacement device from the back, making it convenient to take out the cardboard placed in the storage space. At the same time, the target replacement items in the exchange box 2 can also be replenished by opening the access door, which facilitates the inspection of the interior of the cabinet and has high commercial value.
