Description

Technical Field

[0001] This invention relates to the field of food production and processing equipment technology, specifically a suspended trolley. Background Technology

[0002] Food processing refers to the processing of grains, feeds, vegetable oils and sugars, slaughtering and meats, aquatic products, vegetables, fruits and nuts, as well as tubers, dehydrated vegetables and canned vegetables, using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense.

[0003] Leisure food, also known as fast-moving consumer goods, refers to food consumed during leisure time or rest. The most accurate description is food that is both delicious and enjoyable. Major categories include dried fruit, puffed snacks, candy, and meat products. With the improvement of living standards, leisure food has always been a popular choice among the general public. A visit to a supermarket will reveal a wide variety of leisure foods, including potato chips, French fries, shrimp crackers, rice crackers, dried fruit, tamarind cakes, preserved plums, peanuts, pine nuts, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Leisure food is gradually becoming an essential daily consumer good, and with economic development and rising consumption levels, consumer demand for both the quantity and quality of leisure food continues to grow.

[0004] Suspended conveyor lines are devices for continuously transporting materials in a space. Materials are loaded onto specialized boxes or supports and run along predetermined tracks. The line can ascend, descend, and turn in space, offering flexible layout options and a small footprint. Also known as overhead conveyors, suspended conveyors are continuous transport equipment with enclosed spatial routes, used for the continuous flow transport of workpieces within workshops or between workshops. During continuous flow transport, various sequential processing operations can be performed on the workpieces, such as food processing, and it can operate in harsh environments such as high temperatures and harmful media. Because it makes full use of space and can be integrated with ground-based operations, it is widely used in food processing plants and modern factories.

[0005] In many assembly line production processes, the logistics transportation of materials or components is involved. For example, food processing and garment manufacturing production lines all have logistics conveyor systems. These logistics conveyor systems are typically suspended using steel or steel-plastic structures and are equipped with suspended logistics conveyor trolleys. Currently, the transmission tracks of logistics conveyor systems mostly use a groove structure, with the corresponding logistics trolleys suspended in the grooves via pulley mechanisms. This makes movement inflexible and coordination between the trolleys cumbersome.

[0006] In the food production and processing process, there are many material feeding steps, resulting in serious problems such as material sticking, falling off, and oil leakage. To solve these problems, a suspended trolley structure is designed to eliminate intermediate steps. After the trolley receives the material, it is directly fed into the packaging machine hopper at a fixed point. The suspended trolley can effectively prevent material sticking, leakage, and oil leakage. The whole system is easy to clean, has no dead corners, and is highly efficient. Multiple suspended trolleys can be set up to transport materials simultaneously according to production capacity. Summary of the Invention

A suspension mechanism is provided within the track, and the trolley body is connected to the suspension mechanism. The suspension mechanism includes a mounting frame, a drive wheel A, a positioning wheel, and a drive wheel B. The drive wheel A and drive wheel B are rotatably connected to two sets of mounting frames, respectively. The positioning wheel is also rotatably connected to the mounting frame. The positioning wheel, drive wheel A, and drive wheel B are all slidably connected to the track. The drive wheel A is driven by a drive motor. Drive wheel A, drive wheel B, and positioning wheel are arranged on the suspension mechanism. Under the drive of the drive motor, drive wheel A acts as the driving wheel, driving drive wheel B to slide in the track, and simultaneously driving the trolley body to slide along the track. The positioning wheel can maintain the stability of the trolley body during movement and prevent drive failure.

The mounting plate is connected to the vehicle body and includes an infrared receiver and transmitter, positioned correspondingly. A controller is also mounted on the mounting frame, and a sliding contact line is installed on the track.

[0041] The working principle of this invention is as follows: In use, materials are placed inside the vehicle body 2. The PLC controller of the wiring assembly controls the rotation of the drive motor. The drive motor, through a reducer, controls the rotation of the drive wheel A3. The drive wheel A3, through friction with the track 1, drives the drive wheel B10 and the positioning wheel 4 to slide on the track 1, causing the vehicle body 2 to move along the track 1. During uphill or downhill sections, when the infrared transmitter 20 on the left mounting plate 18 corresponds to the infrared receiver 19 above the right mounting plate 18, the controller 6 controls the electric push rod 11 connected to the left mounting plate 18 to extend, keeping the vehicle body 2 horizontal and preventing materials from tilting and spilling inside. When the infrared transmitter 20 on the left mounting plate 18 corresponds to the infrared receiver 19 below the right mounting plate 18, the controller 6 controls the electric push rod 11 connected to the right mounting plate 18 to extend. The electric push rod 11 extends during operation, and two sets of infrared receivers 19 and infrared transmitters 20 work together to verify and monitor each other. When the vehicle body 2 moves to the material discharge point, the stirring motor controls the stirring frame 8 to move the material inside the vehicle body 2. The scraper 17 can effectively scrape the material on the side wall and bottom of the vehicle body 2 thoroughly, and move the material from the discharge port into the metering cylinder. The metering cylinder can be moved into the metering cylinder according to the required amount of material to be discharged. The cylinder 13 at the bottom of the support plate 14 is controlled to retract, driving the oil receiving plate 16 to move to the right, away from the discharge port of the vehicle body 2. When the oil receiving plate 16 moves half a station away from the discharge port, the cylinder 13 at the top of the support plate 14 is controlled to work, driving the baffle 15 to move to the right, opening the discharge port, so that there is a delay between the opening of the oil receiving plate and the baffle 15 to prevent the material from falling into the oil receiving plate 16 and falling from the discharge port.
