Description

Technical Field

[0001] This utility model relates to the technical field of plastic lunch box processing, specifically a stacking device for processing plastic lunch boxes with a fixed structure. Background Technology

[0002] Plastic food containers are food containers made of thermoplastic materials such as polypropylene and polystyrene. They are lightweight, shatter-resistant, and low-cost, and are widely used, such as in takeout, restaurants, and home settings. In the production and processing of plastic food containers, stacking devices can be used to stack and transport them. As disclosed in CN222663521U, a stacking device for processing plastic lunch boxes includes a support and a stacking component. The support includes a support frame, with rollers vertically rotatably connected to both ends of the bottom surface of the support frame. A stacking component is positioned above the support frame, including a support frame horizontally positioned above the support frame. Multiple stacking baskets are vertically fixed to the top surface of the support frame, with openings on the top surfaces of the stacking baskets. A pressing component is assembled at the opening end of each stacking basket. A sliding plate is horizontally fixed to the support frame, and a sliding column is vertically slidably installed on the sliding plate. The top of the sliding column is fixed to the bottom surface of the support frame, and a support spring is vertically sleeved on the sliding column. This device overcomes the problem that existing clamping plates, which move downwards to squeeze and clamp stacked plastic lunch boxes, can only prevent the stacked plastic lunch boxes from overflowing the stacking device body, but cannot guarantee that the stacked plastic lunch boxes are stacked skewed, affecting the integrity of the stacked plastic lunch boxes. However, existing technologies have problems such as vibration and bumps during transportation, which can easily cause the plates to shake or even bump and be damaged. In addition, the plates are of different sizes, making it inconvenient to stack plates of different sizes and to disassemble and assemble the stacking rack and device. For example, the comparative patents listed above have this problem. To address this issue, we propose a stacking device with a fixed structure for processing plastic lunch boxes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 The present invention provides the following technical solution: To address the problems in existing technologies where vibrations and bumps during transportation can easily cause trays to shake or even collide and become damaged, and where trays of varying sizes are inconvenient to stack, and where disassembly and reassembly of the stacking rack and device are difficult, this solution provides a stacking device for processing plastic lunch boxes with a fixed structure. The device comprises a base 1, multiple base plates 9, and multiple limiting clips 14 positioned on the upper part of the base plates 9. A buffer protection assembly is positioned above the base 1, consisting of an auxiliary side plate 4 fixed to the upper corner of the base 1, a buffer bearing plate 5 fitted to the inner side of the auxiliary side plate 4, movable blocks 6 fixed to the front and rear ends of the buffer bearing plate 5, and a rubber buffer block 7 positioned between the buffer bearing plate 5 and the base 1 that can deform under pressure. The limiting clips 14 are positioned at equal angles on the upper part of the base plates 9, and a fixing component is provided at the lower end of the limiting clips 14 for adjusting and limiting their position. The base plates 9 form a detachable structure on the upper part of the buffer bearing plates 5. like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, firstly, based on the size of the plastic plate and the setting of the fixing components, the fixing components are set at the lower end of the limiting clamp 14. The fixing components include a fixing plate 15 fixed to the outer side of the lower end of the limiting clamp 14, a fixing rod 16 fixed to the upper end of the base plate 9, and a fixing cap 17 for locking and limiting. Protective silicone pads are provided on the inner side of the limiting clamp 14 and the middle of the upper end of the base plate 9. By pulling the fixing plate 15, the fixing plate 15 is fitted to the upper end of the base plate 9. The fixing plate 15 drives the limiting clamp 14 to move on the upper end of the base plate 9, thereby adjusting the spacing between the individual units of the limiting clamp 14 so that the spacing is close to the size of the plastic plate. The fixing plate 15 slides with the fixing rod 16. After the adjustment is completed, by rotating the fixing cap 17 threaded to the outer side of the fixing rod 16, the fixing cap 17 is tightly fitted to the upper end of the fixing plate 15, limiting the distance between the fixing plate 15 and the fixing rod 16, thereby fixing the limiting clamp 14 to the upper end of the base plate 9. Next, place the plastic plates inside the limiting clamp 14 and stack them. The plastic plates adhere to the silicone pad inside the limiting clamp 14. After stacking, the handle 3 on the side of the handheld base 1 is used to push the device, which moves the plate via the moving wheels 2, thus facilitating the transport of the processed plastic plates. During transport, if... Figure 1 and Figure 3 As shown, when vibration and bumps occur, the buffer bearing plate 5 drives the movable block 6 to slide up and down with the auxiliary side plate 4, and the buffer bearing plate 5 moves downward to squeeze the rubber buffer block 7, causing the rubber buffer block 7 to undergo elastic deformation. This can buffer and protect the plastic plate on the base plate 9, preventing the plastic plate from shaking and bumping. When transported to the corresponding location, the plastic plate can be removed from the inside of the limiting clamp 14. In addition, the fixing bolt 12 can be rotated to loosen the connection between the movable baffle 11 and the base plate 9. The movable baffle 11 flips outward and rotates on both sides of the buffer support plate 5. The movable baffle 11 separates from the base plate 9, thereby releasing the restriction on the base plate 9. The connecting handle 13 can be used to pull the base plate 9 upward. The base plate 9 drives the protrusion 10 to separate from the fixing block 8, so that the base plate 9 can be removed from the upper end of the buffer support plate 5. Then, the base plate 9, the limiting clamp 14 and the plate inside the limiting clamp 14 can be directly transported and placed on the corresponding storage rack to prevent the plastic plate from collapsing.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
