Description

Technical Field

[0001] This utility model belongs to the field of automation control technology, and in particular relates to a chain-type automatic tray recycling device. Background Technology

[0002] Currently, the recycling of plates in catering establishments suffers from problems such as low efficiency, difficulty in ensuring hygiene, and high labor costs. Manual plate recycling requires a large amount of labor, easily causes food residue to pollute the environment, and is slow, making it difficult to meet the needs of modern large-scale catering establishments. At present, there are various automatic plate recycling devices on the market, which effectively reduce the need for a large amount of labor for manual plate recycling.

[0003] However, when using traditional automatic tray recycling equipment, the trays are moved to the washing room by a conveyor belt. At the same time, staff need to control the speed and distance of the conveyor belt. However, manually adjusting the speed and distance of the trays will affect the conveyor belt speed, thus reducing the speed at which the conveyor belt can collect the trays. Utility Model Content

[0004] This invention addresses the problem in existing technologies where a conveyor belt moves trays to the washing room, requiring staff to control the belt's speed and distance. However, manually adjusting the trays' speed and distance affects the conveyor belt's transmission speed, leading to a decrease in the trays' retrieval speed. The following technical solution is proposed:

[0005] An automatic chain-type dish recycling device includes: a frame, a recycling platform fixedly installed at the top edge of the frame, a servo motor fixedly installed at the bottom of the frame, a sprocket keyed to the output shaft of the servo motor, several mounting seats installed inside the frame, a common synchronous pulley rotatably connected to one end face of two adjacent mounting seats, a chain rotatably connected to the outer surface of the synchronous pulley and the sprocket, a transmission belt drivingly connected to the outer surface of the synchronous pulley, a recycling box placed at the top of the transmission belt, and two motion sensors installed inside the frame, located above the transmission belt.

[0006] As a preferred embodiment of the above technical solution, each of the motion sensors is fixedly mounted with a baffle plate at its bottom, and the baffle plate is fixedly connected inside the frame.

[0007] As a preferred embodiment of the above technical solution, the number of synchronous pulleys is set to two, and the two synchronous pulleys are respectively located at both ends of the conveyor belt.

[0008] As a preferred embodiment of the above technical solution, baffles two are fixedly connected to the two mounting surfaces away from the servo motor, and baffles three are threadedly connected to one end face of baffles two, and baffles three are fixedly connected to the bottom end of baffles one.

[0009] As a preferred embodiment of the above technical solution, a connecting shaft is provided inside the synchronous wheel located away from the servo motor, and the connecting shaft is snapped into the inside of the baffle.

[0010] As a preferred embodiment of the above technical solution, a support frame is provided inside the conveyor belt, and the support frame is fixedly connected inside the frame.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) By using motion sensors to detect the recycling bins in real time, staff do not need to observe the location of the recycling bins in real time, thereby reducing the number of employees required and effectively reducing human resource costs.

[0013] (2) By adjusting the tension of the transmission belt, the transmission belt is prevented from being too loose or too tight after installation. A loose transmission belt is prone to slipping, which leads to increased wear and even breakage, increases wear between the transmission belt and the synchronous pulley, and shortens the service life of the transmission belt, thus facilitating daily maintenance and upkeep of the transmission belt.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] This utility model provides a chain-type automatic tray recycling device, such as... Figures 1 to 4 As shown, the system includes a frame 1, a recycling platform 2 fixedly installed at the top edge of the frame 1, a servo motor 3 fixedly installed at the bottom inside the frame 1, a sprocket keyed to the output shaft of the servo motor 3, several mounting seats 5 installed inside the frame 1, two adjacent mounting seats 5 are rotatably connected to the same synchronous wheel 6 at one end, the sprocket and the outer surface of the synchronous wheel 6 are rotatably connected to the same chain 4, a transmission belt 7 is driven to the outer surface of the synchronous wheel 6, a recycling box 8 is placed at the top of the transmission belt 7, and two motion sensors 9 are installed inside the frame 1, located above the transmission belt 7, and the motion sensors 9 are electrically connected to the servo motor 3.

[0022] like Figures 2 to 4 As shown, baffles 10 are fixedly installed at the bottom of both motion sensors 9. The baffles 10 are fixedly connected inside the frame 1. The two baffles 10 are located above the edges of both ends of the conveyor belt 7. When the conveyor belt 7 moves the recycling box 8, the motion sensors 9 at both ends detect the recycling box 8 in real time. When the recycling box 8 approaches one of the motion sensors 9, that motion sensor 9 will control the servo motor 3 to turn off. This avoids the need for staff to observe when the conveyor belt 7 moves the recycling box 8, thus avoiding the problem of staff having to manually turn off the conveyor belt 7 when the plate is about to fall.

[0023] like Figures 2 to 4 As shown, the number of synchronous pulleys 6 is set to two, and the two synchronous pulleys 6 are located at both ends of the transmission belt 7. By restricting the transmission belt 7 with the two synchronous pulleys 6, the transmission belt 7 is rotated more stably when driven by the synchronous pulleys 6, avoiding the problem of slippage when the synchronous pulleys 6 drive the transmission belt 7 to rotate, thereby improving the stability of the transmission belt 7 when rotating.

[0024] like Figures 1 to 4 As shown, baffles 2 11 are fixedly connected to the surfaces of the two mounting seats 5 away from the servo motor 3. Baffles 3 12 are threadedly connected to one end face of baffles 2 11. Baffles 3 12 are fixedly connected to the bottom end of baffles 1 10. The overall shape of baffles 2 11 is L-shaped. Baffles 2 11 are slidably connected inside the frame 1. By moving baffles 2 11 closer to the position of baffles 3 12, the movement of baffles 2 11 drives the two mounting seats 5 to move. The two mounting seats 5 drive the synchronous pulleys 6 to move. The moved synchronous pulleys 6 tighten the transmission belt 7, and conversely loosen the transmission belt 7, thus avoiding the problem of the transmission belt 7 being too loose or too tight after installation, thereby facilitating the daily maintenance and upkeep of the transmission belt 7.

[0025] like Figure 4As shown, a connecting shaft is installed inside the synchronous wheel 6, which is far from the servo motor 3. The connecting shaft is snapped into the inside of the baffle 11. When the baffle 11 moves, it drives the connecting shaft to move simultaneously inside the frame 1. When the baffle 11 and the frame 1 snap the connecting shaft, the connecting shaft stops moving and does not affect the rotation of the connecting shaft. At this time, the connecting shaft, which is snapped into the baffle 11 and the frame 1, rotates more stably, avoiding the problem of the connecting shaft shifting when rotating after moving, thereby improving the stability of the connecting shaft when rotating.

[0026] like Figures 2 to 4 As shown, a support frame 13 is provided inside the conveyor belt 7. The support frame 13 is fixedly connected inside the frame 1. When the conveyor belt 7 moves the recycling box 8, the support frame 13 can provide additional support for the conveyor belt 7, making the conveyor belt 7 more stable when moving the recycling box 8. This makes it less likely for the recycling box 8 to shake or fall off when moving on the surface of the conveyor belt 7.

[0027] Working principle: When using this device, staff place the plates to be recycled on the recycling platform 2 for sorting, then place the sorted plates inside the recycling box 8 and start the servo motor 3. The servo motor 3 drives the chain 4 to rotate, the chain 4 drives the synchronous wheel 6 to rotate on the surface of the mounting base 5, and drives the conveyor belt 7 to rotate. The conveyor belt 7 moves the recycling box 8 towards the washing room. The motion sensor 9 monitors the recycling box 8 in real time. When the recycling box 8 moves to the washing room, the motion sensor 9 controls the servo motor 3 to stop moving. Then, the staff takes out the tableware from the recycling box 8 and places the recycling box 8 on the surface of the conveyor belt 7. Then, the servo motor 3 is started in reverse, and the above steps are reversed to move the recycling box 8 back to its original position. The real-time monitoring of the recycling box 8 by the motion sensor 9 eliminates the need for staff to constantly observe the movement of the recycling box 8, thereby reducing the number of employees required and effectively reducing labor costs.

[0028] When the conveyor belt 7 malfunctions, the staff removes the screws fixing the baffle 2 11 and baffle 3 12, then moves baffle 2 11 away from baffle 3 12. Moving baffle 2 11 moves the two mounting seats 5, which in turn move the synchronous pulley 6. After moving, the synchronous pulley 6 tightens the conveyor belt 7, thus adjusting the tension of the conveyor belt 7. This prevents the installed conveyor belt 7 from being too loose or too tight, which would cause it to slip easily, leading to increased wear and even breakage. This would increase the wear between the conveyor belt 7 and the synchronous pulley 6, shorten the service life of the conveyor belt 7, and facilitate the daily maintenance and upkeep of the conveyor belt 7.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
