Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste recycling technology, and in particular to a disposal door for a recycling bin. Background Technology
[0002] Automated recycling bins are widely used, typically featuring enclosed bins and automatically opening / closing doors. These doors are electrically driven. To ensure user safety, all automatic doors are equipped with anti-pinch devices to prevent users' hands from being pinched during the opening and closing process.
[0003] To achieve the opening and closing function, existing products require an electric drive device with the same vertical opening and closing stroke as the delivery door, and the vertical opening and closing distance is limited by the distance between the delivery door and the cabinet. To ensure the opening and closing stroke distance, a longer electric drive device is needed, which, combined with the opening and closing stroke of the delivery door, results in very low utilization of the top space of the enclosed cabinet and increases the cost of the electric actuator, guide rail, and cabinet. Moreover, the anti-pinch function mostly uses complex mechanisms with multiple sensors, which are complex in structure and expensive. Utility Model Content

[0005] The technical solution adopted in this utility model is as follows:
[0006] A recycling bin's delivery door includes a first door body, a second door body, a drive device, an anti-pinch device, and a guide mechanism. The first door body and the second door body are rotatably connected. The anti-pinch device is provided on the first door body. The drive device is installed on the side wall of the recycling bin and connected to the anti-pinch device. The lower end of the second door body is connected to the side wall of the recycling bin through the guide mechanism.
[0007] Preferably, a pivot hinge is also included, through which the lower end of the first door body and the upper end of the second door body are rotatably connected.

The fixing plate is disposed on one side of the guide rail, the connecting plate is disposed on the side wall of the first door body, one end of the rotating shaft passes through the guide rail, the fixing plate, and the connecting plate, and the nut is disposed on one end of the rotating shaft.
[0012] Preferably, the anti-pinch device includes a first bracket, a second bracket, a cylindrical pin, and a metal proximity sensor. The first bracket is installed on the first door body, the second bracket is installed on the output end of the drive device, the first bracket has an inclined waist-shaped hole, the cylindrical pin is installed in the waist-shaped hole and connected to the second bracket, and the metal proximity sensor is provided at one end of the first bracket.
[0013] Preferably, the driving device is an electric driver.
[0014] As a further preferred embodiment, a first reinforcing rib is also included, wherein the first reinforcing rib is provided between the connecting plate and the first door body.

[0016] The above technical solution has the following advantages or beneficial effects:
[0017] (1) In this utility model, by setting the first door body and the second door body, and the first door body and the second door body can rotate relative to each other, the structure can use a shorter electric drive device to achieve a larger opening and closing stroke. Compared with the traditional design, which requires a longer electric drive device with the same opening and closing stroke as the delivery door, this utility model reduces the procurement cost of the electric drive device.
[0018] (2) The anti-pinch device in this utility model only uses the original first bracket to add a metal proximity sensor to achieve the anti-pinch function. There is no need to add a complex mechanism and multiple sensors. Compared with the traditional anti-pinch device, it saves a lot of hardware and design costs.
[0019] (3) In this utility model, the opening and closing of the delivery door can be realized by using a short-stroke drive device, which reduces the occupation of the top space of the closed box and improves the utilization rate of the top space of the box, making the automatic recycling box more flexible in design and layout, and better able to adapt to different installation environments and user needs.
[0020] (4) In this utility model, the opening and closing action of the delivery door is smooth by setting the guide mechanism, so that users do not have to wait too long when delivering items, thus improving delivery efficiency.

[0040] Figure 8 yes Figure 4 Enlarged view at point D; Figure 9 This is a schematic diagram of the normal opening and closing state of the recycling bin's delivery door in this utility model; Figure 10 This is a schematic diagram of the state of the recycling bin's delivery door when it encounters a foreign object that is stuck. Figure 11 This is a side view of the recycling bin when the delivery door is fully closed. Figure 12 This is a side view of the recycling bin's delivery door when it is half-open. Figure 13 This is a schematic diagram of the recycling bin's delivery door when it is fully open. Please refer to [link / reference]. Figures 1 to 13 The diagram illustrates a preferred embodiment of a recycling bin's delivery door, comprising a first door body 1, a second door body 2, a drive unit 3, an anti-pinch device 4, and a guide mechanism 5. The first door body 1 and the second door body 2 are rotatably connected. The anti-pinch device 4 is mounted on the first door body 1. The drive unit 3 is mounted on the side wall of the recycling bin and connected to the anti-pinch device 4. The lower end of the second door body 2 is connected to the side wall of the recycling bin via the guide mechanism 5. In this embodiment, the second door body 2 can rotate relative to the first door body 1, thereby achieving a larger opening and closing stroke. Unlike the traditional method of a single door body opening and closing directly up and down, this design greatly reduces the need for vertical space through the folding and rotating of the door body. When the delivery door is closed, the first door body 1 and the second door body 2 are relatively close together, occupying less space. When the delivery door is opened, the first door body 1 and the second door body 2 unfold by rotation, enabling the delivery of items. The guide mechanism 5 allows the lower end of the second door body 2 to move up and down, ensuring the stability and smoothness of the second door body 2 during the opening and closing process.
[0041] Furthermore, as a preferred embodiment, it also includes a pivot hinge 6, through which the lower end of the first door body 1 and the upper end of the second door body 2 are rotatably connected. See also Figure 8As shown, two pivot hinges 6 are provided between the first door body 1 and the second door body 2. The two pivot hinges 6 are located on both sides of the connection between the first door body 1 and the second door body 2. Each pivot hinge 6 includes a connecting piece and two first pivots rotatably connected to the connecting piece. Mounting holes that cooperate with the first pivots are opened on the side walls of the first door body 1 and the second door body 2. The first pivots are fixedly installed in the mounting holes, and the first pivots are rotatably connected to the connecting piece. In this way, the first door body 1 and the second door body 2 can be connected together, and the second door body 2 can be rotated smoothly relative to the first door body 1.
[0042] Furthermore, as a preferred embodiment, a limiting plate 7 is also included. A limiting plate 7 is provided on the lower side wall of the first door body 1, and the limiting plate 7 is operably in contact with or separate from the second door body 2. The limiting plate 7 is welded and fixed to one side of the lower end of the first door body 1. The limiting plate 7 is used to limit the rotation angle between the second door body 2 and the first door body 1. For details, please refer to [link to relevant documentation]. Figure 3 As shown, when the first door 1 and the second door 2 are fully extended, that is, when the delivery door is fully closed, the limiting plate 7 is in contact with the second door 2. When the delivery door is folded, that is, when it is opened, the limiting plate 7 is separated from the second door 2.
[0043] Furthermore, as a preferred embodiment, the guiding mechanism 5 includes guide rails 501 and rollers 502. The two guide rails 501 are installed on the side wall of the recycling bin and located on both sides of the second door 2. Two rollers 502 are provided on both sides of the lower end of the second door 2, and the two rollers 502 are installed inside the two guide rails 501. The guide rails 501 are connected and fixed to the side wall of the recycling bin by welding or bolting. Specifically, they are installed on the back side wall of the delivery port on the recycling bin. When the first door 1 pulls the second door 2, the second door 2 can drive the rollers 502 to move within the guide rails 501. The arrangement of the rollers 502 and the guide rails 501 can ensure the stability of the movement of the second door 2.
[0044] In this embodiment, a mounting plate 503 and a second reinforcing rib 504 are also included. Two mounting plates 503 are provided on both sides of the lower end of the second door body 2. A roller 502 is rotatably connected to the mounting plate 503, and a second reinforcing rib 504 is provided between the mounting plate 503 and the second door body 2. The mounting plate 503 is fixed to the second door body 2 by welding, while the second reinforcing rib 504 is connected to the second door body 2 and the mounting plate 503 by welding or bolting, further reinforcing the mounting plate 503. The roller shaft of the roller 502 can be welded to the mounting plate 503, allowing the roller 502 to rotate relative to its shaft and move within the guide rail 501, reducing contact friction with the guide rail 501. When the first door body 1 rotates, it drives the second door body 2 to rotate, causing the roller 502 on the second door body 2 to move within the guide rail 501. Figure 1 Taking the direction shown as an example, when the drive device 3 pulls the first door 1 upward, the first door 1 will rotate clockwise around the pivot 801. Since the first door 1 and the second door 2 are hinged, when the first door 1 rotates, it will drive the second door 2 to rotate counterclockwise, so that the second door 2 and the first door 1 are in a position... Figure 1 The folded state shown is the fully open state. This structural design allows the delivery door to achieve a larger opening and closing stroke using a shorter-stroke electric drive unit 3, effectively solving the problems of low utilization of the top space of the container and high cost of related components caused by the long stroke of the electric drive unit 3 in existing products. The delivery door in this embodiment can be applied not only to garbage recycling bins but also to some garbage recycling cabinets.
[0045] Furthermore, as a preferred embodiment, two rotating shaft mechanisms 8 are provided on both sides of the upper end of the first door body 1, and the two rotating shaft mechanisms 8 are connected to two guide rails 501. Each rotating shaft mechanism 8 includes a rotating shaft 801, a fixing plate 802, a nut 803, and a connecting plate 804. The fixing plate 802 is disposed on one side of the guide rail 501, and the connecting plate 804 is disposed on the side wall of the first door body 1. One end of the rotating shaft 801 passes through the guide rail 501, the fixing plate 802, and the connecting plate 804, and the nut 803 is disposed at one end of the rotating shaft 801. In this embodiment, see... Figure 7 As shown, the fixing plate 802 is welded to the guide rail 501, the connecting plate 804 is welded to the first door body 1, and the nut 803 is threadedly engaged with the rotating shaft 801. The fixing plate 802 improves the stability of the rotating shaft 801 installation. The rotating shaft 801 is not threadedly engaged with the guide rail 501 or the fixing plate 802; therefore, adjusting the tightness of the nut 803 is sufficient to ensure the normal rotation of the rotating shaft 801. The rotating shaft 801 allows the first door body 1 to rotate around it when the drive device 3 pulls it upwards.
[0046] Furthermore, as a preferred embodiment, the anti-pinch device 4 includes a first bracket 401, a second bracket 402, a cylindrical pin 403, and a metal proximity sensor 404. The first bracket 401 is mounted on the first door body 1, and the second bracket 402 is mounted on the output end of the drive device 3. The first bracket 401 has an inclined oblong hole 405, and the cylindrical pin 403 is installed in the oblong hole 405 and connected to the second bracket 402. One end of the first bracket 401 is provided with a metal proximity sensor 404. In this embodiment, during the opening and closing of the delivery door, the drive device 3 drives the cylindrical pin 403 to move within the oblong hole 405 of the first bracket 401 through the second bracket 402 until the cylindrical pin 403 moves to the desired position. Figure 9 In the indicated state, the cylindrical pin 403 is in contact with the upper inner wall of the oblong hole 405. The drive device 3 then continues to pull the first door 1, thereby opening and closing the first door 1. When the delivery door is blocked by a foreign object, it will move in the opposite direction to the drive device 3. At this time, the cylindrical pin 403 will slide along the oblong hole 405 until it contacts the lower inner wall of the oblong hole 405. The cylindrical pin 403 will then approach the metal proximity sensor 404, triggering the controller to drive the drive device 3 in the opposite direction to lift the delivery door, thus preventing hand pinching. This structure eliminates the need for an additional anti-pinch mechanism; simply adding a metal proximity sensor 404 to the original first bracket 401 achieves the anti-pinch function, saving manufacturing costs. In this embodiment, the first bracket 401 and the first door 1 can be welded together or connected by bolts.
[0047] In this embodiment, both the first bracket 401 and the second bracket 402 are U-shaped. The metal proximity sensor 404 is connected to one end of the first bracket 401 through a mounting bracket 406, and the mounting bracket 406 and the first bracket 401 are welded together.
[0048] Furthermore, as a preferred embodiment, the drive device 3 is an electric actuator. The electric actuator can be a linear motor or an electric cylinder, etc. In this embodiment, the output end of the drive device 3 is bolted to the second bracket 402, and the drive device 3 is rotatably connected to the recycling bin. This allows the drive device 3 to rotate relative to the recycling bin. This utility model... Figure 1 , Figure 2 as well as Figure 3 The image shown is of one side wall of the recycling bin, where the drop-out port is located. It is not the complete recycling bin. Of course, the structure of the recycling bin is also the existing structure, which can be a rectangular box structure.
[0049] See Figure 4As shown, a hinge seat 9 is provided on the side wall of the recycling bin, and the drive device 3 is connected to the hinge seat 9 by a hinge shaft 10.
[0050] Furthermore, as a preferred embodiment, it also includes a first reinforcing rib 805, which is provided between the connecting plate 804 and the first door body 1. The first reinforcing rib 805 is welded to the connecting plate 804 and the first door body 1, which can increase the stability of the connecting plate 804.
[0051] In this embodiment, see Figure 2 As shown, a display screen 11 can be installed on the side wall of the recycling bin, and a control box 12 can be installed on the inner wall of the recycling bin. The control box 12 can house a controller (PLC or microcontroller), and the display screen 11 is connected to the controller. The controller is connected to the drive device 3 and the metal proximity sensor 404. The display screen 11 can be a touch screen, which can output control signals to the controller, which then controls the drive device 3 to operate. This control method is user-friendly, lowers the operational threshold, and enhances the user experience.
[0052] The anti-pinch device 4 in this embodiment only requires adding a metal proximity sensor 404 to the original first bracket 401 to achieve the anti-pinch function, without the need for additional complex mechanisms and multiple sensors. Compared with the traditional anti-pinch device 4, it saves a significant amount of hardware and design costs.
[0053] In use, a control signal can be input to the controller, which then controls the drive device 3 to pull the first door 1 upwards. The first door 1 rotates around the pivot 801, which in turn pulls the second door 2 to rotate, causing the delivery door to fold. Figure 1 As shown, the delivery door is opened. When it is necessary to close the delivery door, the controller controls the drive device 3 to reverse its movement, pushing the first door 1 downwards. The first door 1 drives the second door 2 to rotate, so that the delivery door is fully closed. Figure 2 The state shown.
[0054] If the delivery door is stuck by a foreign object during the opening and closing process, the cylindrical pin 403 will approach the metal proximity sensor 404 and trigger the controller to drive the drive device 3 in reverse to lift the delivery door, thus preventing hand pinching.
[0055] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
