Description

Technical Field

[0001] This application relates to the field of furnace loading trolley technology, and in particular to a furnace loading trolley with stable load-bearing capacity. Background Technology

[0002] Food-grade loading trolleys are core carrying and transfer equipment specifically designed for heat processing scenarios such as food baking, sterilization, and drying. They are mainly compatible with food-specific heating equipment such as food tunnel ovens, box ovens, and continuous sterilization ovens. Their core function is to safely carry various types of food (or food containers), accurately deliver them into the oven after loading outside, and smoothly remove them after heat processing, ensuring food hygiene, safety, and processing consistency throughout the entire process. Their design strictly adheres to food contact material safety standards (such as GB 4806 series, FDA, etc.), distinguishing them from industrial loading trolleys by emphasizing hygiene, safety, and food compatibility.

[0003] However, the furnace loading trolleys currently on the market have insufficient load-bearing stability, resulting in a high safety factor during food transportation, problems such as food easily falling off, and inflexible movement of the trolley, which can easily cause the trolley to jam.

[0004] Therefore, this application proposes a stable load-bearing furnace trolley. Utility Model Content

[0005] This application proposes a stable load-bearing furnace-loading trolley to solve the problems mentioned in the background art. By setting fixed baffles and movable baffles on the base plate, and the movable baffles resetting under the action of springs, the three fixed baffles and movable baffles form a barrier, solving the problem of food easily falling off the load-bearing plate when the trolley is transferred and moved, thus improving the safety factor during food transfer. Moreover, the frame composed of the base plate and the fixed baffles and movable baffles has a higher stability factor than fixing a cuboid block on each side of the frame body and placing the load-bearing plate on the cuboid block. This can improve the stability and safety of food transfer, greatly enhancing the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution: A stable load-bearing furnace trolley includes a frame body with multiple casters at the bottom, and further includes: a base plate fixedly connected to the frame body, with several rollers rotatably connected inside each base plate; fixed baffles fixedly connected to the top of the base plate, with three fixed baffles on the top of each base plate; movable baffles disposed inside the base plate, with the three fixed baffles on the top of each base plate and the movable baffle forming a U-shape; and a push-pull assembly disposed on the back of the frame body.

[0007] As a preferred embodiment, it further includes: a support plate disposed on the top of the base plate, the bottom surface of which contacts the surface of the roller; and circular holes formed inside the support plate, with four circular holes on each support plate; As a preferred embodiment, it further includes: sliders, which are fixedly connected to both sides of the movable baffle, and there are two sliders on each movable baffle; and a sliding rod, which is fixedly connected to the bottom of the base plate, and each movable baffle slides outside the corresponding sliding rod through the slider, so that the movable baffle is movably connected to the base plate; In a preferred embodiment, it further includes: a limiting block, fixedly connected to the bottom end of the slide rod; and springs, disposed on the outside of the slide rod, wherein the top end of each spring is fixedly connected to the bottom of the slider, and the bottom end of each spring is fixedly connected to the top of the limiting block. In a preferred embodiment, it further includes: a handle, fixedly connected to the bottom of the movable baffle; and a heat insulation sleeve, fitted over the outside of the handle; In a preferred embodiment, the push-pull assembly includes fixing blocks fixedly connected to the vehicle frame, and each of the two fixing blocks has a screw inside, with a push handle fixedly connected to the top of each screw. In a preferred embodiment, it further includes: nuts, rotatably connected to the bottom of the fixing block, and the two nuts are threadedly connected to the screw.

[0008] The beneficial effects of this application are: This stable load-bearing furnace trolley uses fixed and movable baffles on its base plate. The movable baffles are reset by springs, and the three fixed and movable baffles form a barrier, solving the problem of food falling off the load plate during the trolley's movement and improving the safety factor during food transport. The frame formed by the base plate, fixed baffles, and movable baffles has a higher stability factor than a rectangular block fixed on each side of the frame, on which the load plate is placed. This improves the stability and safety of food transport and greatly enhances the practicality of the device. This stable-load-bearing furnace-feeding trolley features rollers inside its base plate, facilitating smooth movement of the support plate and preventing food from falling off due to jamming. A push-pull assembly allows the push handle to be engaged with the corresponding fixing block hole via a screw. Rotating the nut connects the nut to the screw thread, enabling the trolley to move using the push handle. The push handle balances the forces during pushing and pulling, and the inclusion of casters enhances the trolley's flexibility, eliminating jamming and significantly improving the device's practicality.

[0011] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0012] Reference Figure 1-6 A stable load-bearing furnace loading trolley includes a frame body 1 with multiple casters 101 at the bottom. It also includes a base plate 2, fixedly connected to the frame body 1. The frame body 1 and base plate 2 are welded using argon arc welding, a common method in welding food-grade furnace loading trolley frames. Using argon as a protective gas effectively prevents oxidation of the welding area, resulting in high welding quality, aesthetically pleasing weld formation, and a small heat-affected zone, reducing deformation of the frame body 1. Each base plate 2 has several rotatably connected rollers 21 inside. Fixed baffles 3 are fixedly connected to the top of the base plate 2, with three fixed baffles 3 on the top of each base plate 2. Movable baffles 4 are located inside the base plate 2. Both the fixed baffles 3 and the movable baffles 4 are coated with Teflon, which has non-stick, high-temperature resistance, and corrosion resistance properties. Coating the baffle surface with Teflon makes it less likely for food to stick, making it easier to clean. It also provides some resistance to corrosion from acids and alkalis that may be produced during food processing, ensuring that food quality is not affected. The three fixed baffles 3 on the top of each base plate 2 and the movable baffle 4 form a U-shape. The push-pull assembly is located on the back of the frame body 1.

[0013] It also includes: a support plate 11, which is set on the top of the base plate 2. It is made of 304 stainless steel, which is highly corrosion resistant and can resist common acid and alkaline media in food processing (such as sauces and foods with low salt content). It can withstand high temperatures of up to 600℃ and is fully compatible with conventional processes such as baking (180-250℃) and drying (50-120℃). Its surface is smooth and easy to polish, with no dead corners. Its bottom surface is in contact with the surface of the roller 21. Circular holes 12 are opened inside the support plate 11. There are four circular holes 12 on each support plate 11. After the support plate 11 cools down, fingers can be put into the circular holes 12 to facilitate the pull-out of the support plate 11.

[0014] It also includes: sliders 5, which are fixedly connected to both sides of the movable baffle 4, with two sliders 5 on each movable baffle 4; and a sliding rod 6, which is fixedly connected to the bottom of the base plate 2. The surfaces of the sliders 5 and the sliding rod 6 are coated with Teflon coating, which is heat resistant to ≤260℃, non-stick, and has an extremely low coefficient of friction (0.04-0.1), preventing the sliders 5 and the sliding rod 6 from sticking together and making cleaning convenient. Each movable baffle 4 slides outside the corresponding sliding rod 6 via the sliders 5, so that the movable baffle 4 is movably connected to the base plate 2. The sliding of the sliders 5 outside the sliding rods 6 is used to limit the sliding trajectory of the movable baffle 4.

[0015] It also includes: a limiting block 7, fixedly connected to the bottom end of the slide rod 6; and a spring 8, set on the outside of the slide rod 6. The spring 8 is made of 304 stainless steel, which is highly corrosion-resistant and can resist the erosion of water vapor and neutral cleaning liquid in food workshops. It is rust-free and can withstand high temperatures up to 300℃. The top of each spring 8 is fixedly connected to the bottom of the slider 5, and the bottom is fixedly connected to the top of the limiting block 7. By setting up the slider 5, slide rod 6, limiting block 7 and spring 8, the movable baffle 4 is reset under the action of the spring 8.

[0016] It also includes: a handle 9, fixedly connected to the bottom of the movable baffle 4; a heat insulation sleeve 10, fitted over the handle 9; adopting a composite structure of "fiberglass blanket (inner heat insulation) + fiberglass cloth (outer protection)," the outer layer can be waterproofed (such as with a silane coating) to improve washability, and the edges are sewn with stainless steel wire (food-grade 304). Stainless steel wire is used to prevent fiber shedding and enhance structural stability. It can withstand high temperatures of 500-600℃, fully covering the conventional process temperatures of food baking (180-250℃) and sterilization (60-120℃). It has a low thermal conductivity (≤0.04W / (m·K)) and excellent heat insulation effect, which can effectively block the heat inside the furnace from being conducted to the outside of the trolley, thus avoiding burns to the operator. When it is necessary to remove the support plate 11, the handle 9 pulls down the movable baffle 4. After the support plate 11 cools down, the fingers can be hooked into the circular hole 12 to facilitate the removal of the support plate 11. When the support plate 11 is at a high temperature, it can also be pulled out by hooking it into the circular hole 12. By setting a heat insulation sleeve 10 outside the handle 9, the heat is insulated at high temperatures to avoid burns.

[0017] The push-pull assembly includes a fixing block 13, which is fixedly connected to the frame body 1. Each of the two fixing blocks 13 has a screw 15 inside, and the top of the two screws 15 is fixedly connected to a push handle 14. The push handle 14 can balance the force during push-pull, and together with the caster wheel 101, it makes the trolley more flexible when moving and solves the problem of jamming when the trolley moves.

[0018] It also includes: nuts 16, which are rotatably connected to the bottom of the fixing block 13, and the two nuts 16 are threadedly connected to the screw rod 15; by setting a push-pull assembly, the pusher 14 is locked in the corresponding hole of the fixing block 13 through the screw rod 15, and then the nuts 16 are rotated to make the nuts 16 threadedly connected to the screw rod 15, and the trolley can be moved by the pusher 14.

[0019] Working principle: In use, one end of the support plate 11 is placed on the base plate 2. Under pressure, the movable baffle 4 extends inward into the base plate 2 and is at the same level as the base plate 2. When the bottom of the support plate 11 contacts the top of the base plate 2, the support plate 11 is pushed into the back of the frame 1. During the pushing process, the rollers 21 set in the base plate 2 help the support plate 11 to be pushed smoothly to prevent jamming and food from falling off the support plate 11. By setting the fixed baffle 3 and the movable baffle 4 on the base plate 2, the movable baffle 4 is reset under the action of the spring 8. The three fixed baffles 3 and the movable baffle 4 form a barrier to solve the problem of food falling off the support plate 11 when the trolley is transferred, thus improving the safety factor during food transfer. The frame formed by the base plate 2 and the fixed baffles 3 and the movable baffle 4 has a higher stability factor than the frame 1 with a rectangular fixed block fixed on each side. The support plate 11 is placed on the rectangular fixed block, which can improve the stability and safety of food transfer.

[0020] When it is necessary to remove the support plate 11, the handle 9 pulls down the movable baffle 4. After the support plate 11 cools down, the fingers can be hooked into the circular hole 12 to facilitate the removal of the support plate 11. When the support plate 11 is at a high temperature, it can also be pulled out by hooking it into the circular hole 12. By setting a heat insulation sleeve 10 on the outside of the handle 9, the heat is insulated at high temperatures to avoid burns.

[0021] By setting up a push-pull assembly, the pusher 14 is locked into the corresponding hole of the fixing block 13 by the screw 15. Then, the nut 16 is rotated to make the nut 16 threadedly connected to the screw 15. The trolley can be moved by the pusher 14. The pusher 14 can balance the force when pushing and pulling. Combined with the caster wheel 101, it makes the trolley more flexible when moving and solves the problem of jamming when moving the trolley.
