Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a uniformly dried storage bracket for plastic products. Background Technology

[0002] Drying is a crucial step in the production of plastic products. Most existing plastic product drying equipment uses a simple rack structure, placing the plastic products on trays and sending them into the drying chamber. This traditional drying rack has several significant drawbacks: First, uneven hot air flow leads to uneven heating of the plastic products, with some areas over-dried and others under-dried; second, the fixed tray spacing cannot be adjusted for different sized plastic products, reducing space utilization; and third, it is inconvenient to load and unload, requiring workers to pull out the entire tray to remove or place products, which is laborious and results in significant heat loss.

[0003] Chinese patent CN221387310U discloses a drying device for uniformly heated plastic products. A first and second mounting strip connect a rack, allowing the rack to be pulled out and rotated. A baffle plate is installed at the end of the rack to prevent heat dissipation. While this device improves heat retention, it still falls short in terms of uniform hot air distribution. Another patent, CN218210425U, introduces an adjustable-spacing plastic drying rack. Through the cooperation of sliders, insert rods, and fixing strips, the spacing between the trays can be adjusted, but its hot air uniformity still has room for improvement.

[0004] Furthermore, existing drying tray racks often neglect the optimization of hot air flow paths. For example, airflow in conventional drying rooms mainly includes two modes: horizontal flow and vertical flow. In the horizontal flow mode, the surface material on the drying rack tray dries faster, but the heating is uneven; while in the vertical flow mode, the upper and lower parts of the drying rack are heated unevenly, resulting in different drying rates.

[0005] Therefore, there is an urgent need for a storage rack that can heat plastic products evenly, has adjustable spacing, and is easy to place and retrieve, in order to improve drying efficiency and quality. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a uniformly dried storage rack for plastic products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A plastic product uniform drying rack includes a movable base, with columns welded to the top four corners of the movable base, and the four columns forming a fixed frame. Both ends of the fixed frame are connected to air guide plates by screws.

[0009] Adjustable trays are slidably installed on the inner wall of the fixed frame, which are evenly distributed in the vertical direction. The adjustable trays include a C-shaped mounting frame, and slots are opened on both inner walls of the mounting frame. Placement plates are slidably inserted into the two slots. Ventilation holes are evenly distributed on the placement plates. A handle is fixed on the outer wall of the placement plate near the opening of the mounting frame.

[0010] The adjustable tray has connecting rods installed at the four bottom corners, and water guide plates are fixed at the bottom of the four connecting rods, with the water guide plates set at an angle.

[0011] Preferably, the outer wall of the air guide plate is provided with an air inlet, and the inner wall of the air inlet is equipped with equidistant air distribution louvers.

[0012] Preferably, one side of the inner wall of the column has equally spaced fixing holes along the vertical direction, and one side of the inner wall of the column has a guide groove along the vertical direction.

[0013] Preferably, each end of the outer wall on both sides of the mounting bracket is provided with a guide slider and a spring plunger in sequence. The guide slider is slidably connected to the inner wall of the guide groove, and the spring plunger is fixedly engaged with the fixing hole.

[0014] Preferably, the movable base includes a base plate, and omnidirectional wheels are installed at the four bottom corners of the base plate.

[0015] Preferably, the water guide plate forms an angle of °-° with the horizontal direction, and a water receiving groove is provided on the upper part of the water guide plate, and a drain outlet is provided on the lower outer wall of the water guide plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Achieved three-dimensional uniform drying: By setting air guide plates at both ends of the fixed frame, and in conjunction with the ventilation holes on the placement plate, a three-dimensional hot air channel is formed that runs through the frame, which effectively solves the problem of uneven hot air distribution in traditional drying racks, ensuring that plastic products on each layer are heated evenly and improving the consistency of drying quality.

[0018] 2. Flexible space adjustment is achieved: Through the sliding cooperation of the guide slider and the guide groove, combined with the positioning structure of the spring plunger and the fixing hole, the height position of each shelf can be quickly adjusted to adapt to the drying needs of plastic products of different sizes, which greatly improves the applicability and space utilization of the shelf.

[0019] 3. Effectively solves the problem of water accumulation: By setting up inclined water guide plates and water collection tanks, the condensate generated during the drying process can be collected and discharged in a timely manner, avoiding water accumulation from contaminating plastic products, ensuring a clean and dry drying environment, and improving product quality.

[0020] 4. Improved ease of operation: The pull-out shelf design, combined with the handle structure, makes it easy to pick up and put down plastic products; the casters make the entire shelf flexible to move, greatly reducing the labor intensity of workers and improving production efficiency.

[0021] 5. Simple and practical structure: The entire shelving unit has a reasonable structural design, reliable connections between components, low manufacturing cost, and is easy to maintain and clean, making it particularly suitable for the mass production needs of small and medium-sized plastic product enterprises.

[0022] In summary, this storage rack achieves three-dimensional and uniform drying. By setting air guide plates at both ends of the fixed frame, in conjunction with the ventilation holes of the placement plate, a hot air channel is formed throughout the rack, ensuring that products on each layer are heated evenly. The guide slider and spring plunger structure can quickly adjust the height of the tray to accommodate products of different sizes. The inclined water guide plate effectively collects and removes condensate, avoiding water accumulation and contamination. The pull-out placement plate and universal wheels make it convenient to pick up and put down and move flexibly. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1, referring to Figure 1-5 A plastic product uniform drying rack mainly includes components such as a movable base 1, a column 2, an air guide plate 3, an adjustable tray 4, and a water guide plate 5.

[0031] The mobile base 1 consists of a base plate 13 and four casters 14. The casters 14 are preferably industrial casters with brakes, which are easy to move and can maintain stability during operation. The base plate 13 is made of stainless steel, which has sufficient strength and corrosion resistance.

[0032] Four uprights 2 are vertically welded to the top four corners of the movable base 1 to form a sturdy rectangular fixing frame. The uprights 2 adopt a square tube structure, with equally spaced fixing holes 6 on one side of the inner wall along the vertical direction, and continuous guide grooves 7 on the other side. The spacing of the fixing holes 6 can be designed according to the height specifications of commonly used plastic products, usually with an interval of 50mm or 100mm.

[0033] The air guide plate 3 is connected to both ends of the fixed frame, namely the front and rear facades, by screws. The air guide plate 3 has an air inlet, and the air inlet is equipped with equidistant air distribution louvers 15. The angle of the air distribution louvers 15 is adjustable to guide hot air into the frame evenly and avoid excessive local wind speed.

[0034] The adjustable tray 4 is connected to the column 2 via a guide slider 18 and a spring plunger 19. The guide slider 18 is embedded in the guide groove 7 to ensure that the tray can only move smoothly in the vertical direction. The spring plunger 19 cooperates with the fixing hole 6 to fix the height position of the tray. When it is necessary to adjust the floor height, simply press the button of the spring plunger 19 to make it retract from the fixing hole 6, and the tray can be moved up and down. After adjusting to the appropriate position, the spring plunger 19 will automatically spring into the corresponding fixing hole to complete the fixation.

[0035] The adjustable tray 4 is composed of components such as mounting frame 8 and placement plate 10. The mounting frame 8 has a "C" shaped structure and slots 9 on the inner walls of both sides. The placement plate 10 is slidably connected to the mounting frame 8 through the slots 9 and can be pulled out about two-thirds of its length for easy handling of plastic products. The placement plate 10 has dense ventilation holes 11. The size of the holes is necessary to ensure that hot air can pass through smoothly while preventing small plastic products from falling. The front end of the placement plate 10 is fixed with a handle 12 for easy pulling operation.

[0036] The water guide plate 5 is fixed to the bottom of the adjustable tray 4 by four connecting rods, forming an angle of 15°-30° with the horizontal direction. The upper part of the water guide plate 5 has a water receiving groove 16 for collecting the condensate dripping from the upper tray. The lower side of the outer wall has a drain outlet 17, which is connected to a drain pipe to guide the accumulated water to the collection container. The inclined design of the water guide plate 5 ensures that the accumulated water can flow smoothly to the drain outlet and avoid water retention.

[0037] Working principle:

[0038] Hot air circulation process: Hot air is drawn out from the drying equipment and enters the inside of the rack through the air inlet on the air guide plate 3. The air distribution louver 15 disperses the airflow, so that the hot air flows evenly to each layer of trays. The hot air passes through the ventilation holes 11 on the placement plate 10 and comes into full contact with the plastic products before continuing to flow to the other side, forming a through-flow circulating airflow. This design effectively avoids the problem of hot air dead zones in traditional drying racks and ensures that each layer of plastic products is heated evenly.

[0039] Shelf height adjustment process: When it is necessary to adjust the spacing between the shelves, the operator presses the spring plunger 19 buttons at the four corners of the shelf at the same time, so that the plunger head retracts from the fixing hole 6 of the column 2. Then, the shelf is moved up or down to the appropriate height. The spring plunger button is released, and the plunger head automatically springs into the corresponding fixing hole under the action of the spring, thus completing the fixing. Each shelf can be adjusted independently, or it can be arranged at equal intervals according to the size of the products, which greatly improves the adaptability of the shelf.

[0040] Drainage process: During the drying process, condensation will be generated on the surface of plastic products. Water droplets fall through the ventilation holes 11 of the placement plate 10 to the bottom water guide plate 5. Since the water guide plate 5 is set at an angle of 15°-30°, the water will naturally flow to the lower side and be discharged through the drain outlet 17. The water on the upper tray will also drip onto the lower water guide plate and be discharged in a unified manner, effectively maintaining the dry environment of the plastic products.

[0041] Retrieval and placement process: When it is necessary to retrieve or place plastic products, the operator pulls the placement plate 10 out of the mounting frame 8 through the handle 12. At this time, a certain length of the placement plate remains in the slot to ensure safety. The pull-out design of the placement plate 10 allows the operator to retrieve or place products conveniently without having to move the entire tray out, which greatly improves work efficiency.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
