Description

Technical Field

[0001] This utility model relates to a PC back panel baking transfer vehicle. Background Technology

[0002] Screen printing, a type of stencil printing, is one of the four major printing methods, along with offset printing, letterpress printing, and gravure printing. Stencil printing includes methods such as mimeographing, stencil printing, inkjet printing, and screen printing. During printing, ink is forced through the mesh of the image area onto the substrate by a squeegee, creating an image identical to the original artwork. Screen printing equipment is simple, easy to operate, and the printing and plate-making processes are straightforward, inexpensive, and highly adaptable. Common applications of screen printing include: color paintings, posters, business cards, book covers, product labels, and printed textiles.

[0003] The screen printing drying line is an important step in screen printing. Currently, after the PC back panel is baked in the baking oven, it needs to be cooled and transferred to the next process. At present, the PC back panel is usually stacked directly on a trolley for transfer, which is not conducive to heat dissipation. This will result in poor heat dissipation and deformation of the PC back panel, affecting subsequent processing and the quality of the finished product. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a PC back panel baking transfer cart that is not only reasonably structured, but also convenient and fast.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a PC back panel baking transfer cart, including a main body, characterized in that: a plurality of shelves are rotatably connected to the main body along the height direction, one end of each shelf is stretched and unfolded by an elastic component to support the PC back panel or retract and close, the elastic component includes a spring, the two ends of which are respectively hooked to the shelf and a hinge rod, the other end of the hinge rod is hinged to the main body; the other end of each shelf is fixedly provided with a pad, the top of each pad is recessed with a limiting groove for the bottom of the upper pad to be inserted and limited.

[0006] Furthermore, hooks are fixedly connected to both ends of the spring, and hook ears are fixedly provided on the side ends of the shelf to facilitate hook attachment, with holes provided on the hook ears.

[0007] Furthermore, the hinge rod has a hanging hole at the end away from the hinge for attaching a hook.

[0008] Furthermore, the pad includes a fixed plate covering the end corner of the shelf, and the lower end of the fixed plate extends in an arc direction with a support foot with a cross-section of approximately triangular shape, and the limiting groove is formed on the fixed plate.

[0009] Furthermore, each shelf is covered with a heat dissipation mesh.

[0010] Furthermore, the shelf is composed of a square frame and cross braces erected within the square frame.

[0011] Furthermore, the main body is provided with a number of circular holes spaced apart along its height direction for rotational connection with the shelf, and the ends of the square frame are symmetrically protruding with pins that pass through the circular holes for rotational connection.

[0012] Furthermore, the main vehicle body consists of a base plate, a fixing frame, and casters. The fixing frame extends vertically and is fixed to the base plate in an L-shape at its bottom. The casters are installed at the bottom of the base plate.

[0013] Furthermore, the externally fixed bracket facilitates the pushing and pulling of handles.

[0014] Furthermore, a pressure bar is rotatably connected to the top of the main body for unfolding and pressing against the top shelf.

[0015] Compared with the prior art, the present invention has the following advantages: the PC back panel baking transfer cart has a simple structure, and the transfer is more stable and convenient. The opening and closing of the shelves helps to separate the PC back panels, which is conducive to heat dissipation and avoids damage caused by direct stacking.

Detailed Implementation

[0023] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0024] like Figures 1-5 As shown, a PC back panel baking transfer cart includes a main body 1, characterized in that: a plurality of shelves 2 are provided on the main body along the height direction, each shelf being rotatably connected to the main body; one end of each shelf is stretched and unfolded by an elastic component to support the PC back panel or retracted and closed; the elastic component includes a spring 3, the two ends of which are respectively hooked to the shelf and a hinge rod 4; the other end of the hinge rod is hinged to the main body; a foot 5 is fixed to the other end of each shelf, and a limiting groove 6 is recessed at the top of each foot for the bottom of the upper foot to be inserted and limited.

[0025] In this embodiment of the utility model, hooks 7 are fixedly connected to both ends of the spring, and hanging ears 8 are fixedly provided on the side ends of the shelf to facilitate hooking, and holes are provided on the hanging ears.

[0026] In this embodiment of the utility model, the hinge rod has a hanging hole 9 at the end away from the hinge for hooking.

[0027] In this embodiment of the utility model, the pad includes a fixed plate 10 covering the end corner of the shelf, and a support foot 11 with a triangular cross-section extending arcward from the lower end of the fixed plate. The limiting groove is formed on the fixed plate.

[0028] In this embodiment of the utility model, heat dissipation mesh 12 is laid on each shelf.

[0029] In this embodiment of the utility model, the shelf is composed of a square frame 13 and support rods 14 arranged in a crisscross pattern within the square frame.

[0030] In this embodiment of the utility model, the main body is provided with a plurality of circular holes 15 at intervals along its height direction for rotational connection with the shelf, and the ends of the square frame are symmetrically protruding with pins 16 for rotational connection through the circular holes.

[0031] In this embodiment of the present invention, the main vehicle body is composed of a base plate 17, a fixing frame 18 and a universal wheel 19. The fixing frame extends vertically and is fixed to the base plate at the bottom in an L-shape. The universal wheel is installed at the bottom of the base plate.

[0032] In this embodiment of the utility model, the fixing frame is externally fixed with a handle 20 that facilitates pushing and pulling.

[0033] In this embodiment of the utility model, a pressure bar 21 for unfolding and pressing against the top shelf is rotatably connected to the top of the main vehicle body.

[0034] The working principle of this utility model embodiment is as follows: During use, the transfer cart is moved to the baking station to wait for the PC back panel to be baked. The pressure bar is rotated 90 degrees towards the handle to avoid affecting the closing of the shelf. Then, the shelf is rotated upwards from top to bottom, causing the spring to contract and keep each shelf in an inclined state. When the bottom shelf is flipped, it is stopped to keep it in a horizontal state, and the baked PC back panel is placed on its surface. Then, the upper shelf is flipped horizontally in sequence. It remains stable under the action of the spring being stretched to the horizontal. The pressure of the PC back panel further stabilizes it and prevents it from flipping. The pads are inserted into the limiting grooves of the lower shelf. After the top shelf is flipped, the pressure bar is rotated outwards by 90 degrees to avoid the spring contracting under the bumpy transportation state, which would cause the PC back panel to tilt. The layers are placed separately and the heat dissipation mesh provides the best heat dissipation effect, making it more stable during transportation and achieving the best heat dissipation effect.

[0035] This utility model is not limited to the preferred embodiment described above. Anyone can derive other various forms of PC back panel baking transfer carts based on the teachings of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model should be considered within the scope of this utility model.
