Description

Technical Field

[0001] This utility model belongs to the field of plastics technology, and more specifically, it relates to a drying device for plastic products. Background Technology

[0002] Plastic products are a general term for daily and industrial products made primarily from plastics. They include products manufactured using all processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with plasticity.

[0003] In the process of manufacturing plastic products, it is necessary to dry the surface of the plastic products in order to remove some of the residual moisture inside or on the surface of the plastic products.

[0004] However, existing methods for drying plastic products typically involve placing them directly on trays inside the drying oven. After cleaning, a large amount of water droplets often remain on the surface of the plastic products. Due to the uneven distribution of residual moisture, the rate of water evaporation varies during the drying process. Some areas of the plastic product, due to excessive moisture, require a longer time to dry completely, while areas with less moisture may dry prematurely. This reduces overall drying efficiency, increases drying costs, and consequently diminishes the practicality of the plastic product drying equipment. Utility Model Content

[0005] In existing methods of drying plastic products, the products are typically placed directly on trays within a drying oven. However, after cleaning, a large amount of water droplets often remain on the surface of the plastic products. Due to the uneven distribution of residual moisture, the evaporation rate varies during the drying process. Some areas of the plastic product, due to excessive moisture, require a longer drying time, while areas with less moisture may dry prematurely. This reduces overall drying efficiency, increases drying costs, and consequently diminishes the practicality of the plastic product drying device. This invention proposes a plastic product drying device to overcome the aforementioned technical problems in existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a drying device for plastic products, including a drying chamber. Multiple placement frames are arranged inside the drying chamber, and multiple water-shaking mechanisms are arranged between the inner walls of the left and right sides of the drying chamber. The lower surface of each placement frame contacts the water-shaking mechanism, which drives the placement frame to shake up and down, thereby shaking off water droplets from the surface of the plastic products to accelerate the drying process. Two positioning blocks are fixedly connected to the right side surface of the drying chamber, and a driving mechanism is provided on each positioning block. The driving mechanism drives the multiple water-shaking mechanisms to shake simultaneously. Each water-shaking mechanism is equipped with a drainage mechanism to drain the water shaken off the surface of the plastic products into the drying chamber.

[0008] Furthermore, the water-shaking mechanism includes two limiting frames, which are respectively fixedly connected to the inner walls of the left and right sides of the drying box. The limiting frames are U-shaped, and the outer surfaces of the front and rear sides of the placement frame are slidably connected to the two vertical plates of the limiting frames.

[0009] Furthermore, limiting sliders are fixedly connected to the outer surfaces of the left and right sides of the placement frame, and the outer surfaces of the two limiting sliders facing away from each other are slidably connected to the inner walls of the left and right sides of the drying box. Limiting blocks are fixedly connected to the inner walls of the left and right sides of the drying box, and two sliding rods are slidably sleeved on each limiting block. Support blocks are fixedly connected to the lower ends of the sliding rods.

[0010] Furthermore, the lower surface of the support block contacts the upper surface of the limiting slider, and the upper ends of the corresponding two sliding rods are fixedly connected to limiting blocks. A spring is fixedly connected between the lower surface of the limiting block and the upper surface of the support block. The spring is slidably sleeved on the outer surface of the corresponding sliding rod. Multiple fixed shafts are rotatably connected between the inner walls of the left and right sides of the drying box. The outer surface of each fixed shaft is fixedly sleeved with a protrusion, and the outer surface of the protrusion contacts the lower surface of the placement frame.

[0011] Furthermore, the drainage mechanism includes a placement net, which is fixedly fitted inside the placement frame. The bottom wall of the placement frame is inclined. A first drain pipe communicating with the interior of the placement frame is fixedly connected to the lower surface of the placement frame. A plurality of second drain pipes are fixedly connected to the right side surface of the drying box. The left end of the second drain pipe penetrates into the drying box. A spring hose is provided between the end of the second drain pipe penetrating into the drying box and the lower end of the first drain pipe.

[0012] Furthermore, the driving mechanism includes a rotary motor, which is fixedly connected to the upper surface of the positioning block located on the upper side. Positioning rods are rotatably sleeved on the two positioning blocks, and the upper ends of the positioning rods are fixedly connected to the rotation output shaft of the rotary motor.

[0013] Furthermore, a plurality of first bevel gears are fixedly sleeved on the outer surface of the positioning rod, and the right end of the fixed shaft rotatably extends through the right side surface of the drying box. The right end of the fixed shaft is fixedly connected to a second bevel gear, and the second bevel gear meshes with the corresponding first bevel gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses the vibration of plastic products on a placement net to shake off excess water, preventing excessive water accumulation and facilitating the collection of excess water. Furthermore, the up-and-down vibration of the plastic products increases air circulation under them, resulting in more uniform drying, faster drying process, and improved drying efficiency, thereby increasing the practicality of the plastic product drying device.

[0016] 2. Because the bottom wall of the placement frame is inclined, water will enter the second drain pipe through the first drain pipe and the spring hose and be discharged into the drying box. This allows the water to be collected and reused, which is more environmentally friendly. It also avoids excess water in the drying box from increasing the humidity inside the drying box, thereby increasing the practicality of the plastic product drying device.

[0017] 3. This utility model allows the limiting block to be pulled upwards, causing the limiting block to move the sliding rod and support block upwards. Then, the placement frame is pulled upwards, causing the placement frame to slide upwards along with the protrusions on both sides until they no longer contact the limiting frame. At this point, the placement frame is separated from the limiting frame. The placement frame can then be pulled forward to remove it from the drying chamber, making it easier to clean and maintain. This increases the practicality of the plastic product drying device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-7As shown, this utility model is a plastic product drying device, including a drying box 1. Multiple placement frames 11 are arranged inside the drying box 1. Multiple water-shaking mechanisms are arranged between the left and right inner walls of the drying box 1. The lower surface of each placement frame 11 contacts the water-shaking mechanism. The water-shaking mechanism drives the placement frame 11 to shake up and down, thereby shaking off water droplets from the surface of the plastic product to accelerate the drying process. Two positioning blocks 2 are fixedly connected to the right side surface of the drying box 1. A driving mechanism is provided on each positioning block 2 to drive the multiple water-shaking mechanisms to shake simultaneously. Each water-shaking mechanism is equipped with a drainage mechanism to drain the water shaken off the surface of the plastic product into the drying box 1.

[0032] In use, the plastic products are placed in the placement frame 11, and then the drive mechanism is activated to drive multiple water-shaking mechanisms to operate simultaneously. The water-shaking mechanisms can cause the placement frame 11 to vibrate up and down, thereby causing the plastic products in the placement frame 11 to shake up and down, so as to shake off the water droplets on the surface of the plastic products. The shaken water flows into the drainage mechanism through the bottom wall of the placement frame 11 and is then discharged into the drying chamber 1 through the drainage mechanism. This can realize the recovery of excess water, avoid water increasing the humidity in the drying chamber 1, and thus improve the drying efficiency of plastic products.

[0033] In one embodiment, the above-mentioned water-shaking mechanism includes two limiting frames 9, which are fixedly connected to the inner walls of the left and right sides of the drying box 1, respectively. The limiting frames 9 are U-shaped, and the outer surfaces of the front and rear sides of the placement frame 11 are slidably connected to the two vertical plates of the limiting frames 9.

[0034] Limiting sliders 17 are fixedly connected to the outer surfaces of the left and right sides of the placement frame 11. The outer surfaces of the two limiting sliders 17 facing away from each other are slidably connected to the inner walls of the left and right sides of the drying box 1. Limiting blocks 10 are fixedly connected to the inner walls of the left and right sides of the drying box 1. Two sliding rods 14 are slidably sleeved on each limiting block 10. Support blocks 16 are fixedly connected to the lower ends of each sliding rod 14.

[0035] The lower surface of the support block 16 contacts the upper surface of the limiting slider 17. The upper ends of the two corresponding sliding rods 14 are fixedly connected to the limiting blocks 13. A spring 15 is fixedly connected between the lower surface of the limiting block 10 and the upper surface of the support block 16. The spring 15 is slidably sleeved on the outer surface of the corresponding sliding rod 14. A plurality of fixed shafts 6 are rotatably connected between the inner walls of the left and right sides of the drying box 1. A protrusion 7 is fixedly sleeved on the outer surface of each fixed shaft 6. The outer surface of the protrusion 7 contacts the lower surface of the placement frame 11.

[0036] In one embodiment, the drainage mechanism includes a placement net 12, which is fixedly fitted inside the placement frame 11. The bottom wall of the placement frame 11 is inclined. A first drain pipe 18 communicating with the interior of the placement frame 11 is fixedly connected to the lower surface of the placement frame 11. A plurality of second drain pipes 19 are fixedly connected to the right side surface of the drying chamber 1. The left end of the second drain pipe 19 penetrates into the drying chamber 1. A spring hose is provided between the end of the second drain pipe 19 penetrating into the drying chamber 1 and the lower end of the first drain pipe 18.

[0037] Plastic products are placed on the placement net 12 for drying. The moisture on the surface of the plastic products drips onto the bottom wall of the placement frame 11 through the placement net 12. Because the bottom wall of the placement frame 11 is inclined, the water will enter the second drain pipe 19 through the first drain pipe 18 and the spring hose and be discharged into the drying box 1. The water can be collected and reused, which is more environmentally friendly and avoids excess water in the drying box 1 from increasing the humidity in the drying box 1, thereby increasing the practicality of the plastic product drying device.

[0038] In one embodiment, the driving mechanism includes a rotary motor 3, which is fixedly connected to the upper surface of the positioning block 2 located on the upper side. Positioning rods 4 are rotatably sleeved on the two positioning blocks 2, and the upper ends of the positioning rods 4 are fixedly connected to the rotation output shaft of the rotary motor 3.

[0039] Multiple first bevel gears 5 are fixedly sleeved on the outer surface of the positioning rod 4. The right end of the fixed shaft 6 rotatably extends through the right side surface of the drying box 1. The right end of the fixed shaft 6 is fixedly connected to a second bevel gear 8, and the second bevel gear 8 meshes with the corresponding first bevel gear 5.

[0040] The plastic product is placed on the placement net 12 inside the placement frame 11. The rotation motor 3 is started, which can drive the positioning rod 4 to rotate. The rotation of the positioning rod 4 can drive the multiple first bevel gears 5 fixed on it to rotate.

[0041] Because the first bevel gear 5 and the second bevel gear 8 are meshed, they synchronously drive multiple fixed shafts 6 to rotate. The rotation of the fixed shafts 6 synchronously drives the protrusions 7 to rotate. When the protrusions 7 rotate to the point where their protruding ends face upwards, the protrusions 7 exert an upward pushing force on the placement frame 11, causing the placement frame 11 to move upwards. The upward movement of the placement frame 11 drives the limiting slider 17, the support block 16, the limiting block 13, and the sliding rod 14 to move upwards synchronously. During this process, the spring 15 is compressed and deforms. When the protrusions 7 rotate to the point where their protruding ends face downwards, under the action of the release force of the spring 15, the limiting slider 17 is synchronously pushed. The support block 16, the limiting block 13, the sliding rod 14, and the placement frame 11 move downwards. In summary, each rotation of the protrusion 7 causes the placement frame 11 to move up and down once, thereby causing the plastic product to vibrate up and down once on the placement net 12. During this process, excess water on the plastic product can be shaken off, preventing excessive water accumulation on the plastic product and facilitating the collection of excess water. Furthermore, the up and down vibration of the plastic product can increase the air circulation under the plastic product, thereby making the plastic product dry more evenly, accelerating the drying process, improving drying efficiency, and thus increasing the practicality of the plastic product drying device.

[0042] In this design, spring 15 is used to press the limiting slider 17 between the support block 16 and the horizontal plate of the limiting frame 9.

[0043] In this design, the limiting block 13 is pulled upwards, causing the limiting block 13 to move the sliding rod 14 and the support block 16 upwards. Then, the placement frame 11 is pulled upwards, causing the placement frame 11 to slide the protrusions 7 on both sides upwards until they no longer contact the limiting frame 9. At this point, the placement frame 11 is disengaged from the limiting frame 9. The placement frame 11 can then be pulled forwards, allowing it to be pulled out of the drying chamber 1. This facilitates the cleaning and maintenance of the placement frame 11, making it more convenient and increasing the practicality of the plastic product drying device.

[0044] In this design, the second drain pipe 19 is located on the lower side of the corresponding placement frame 11 to facilitate the drainage of water from the placement frame 11. The end of the second drain pipe 19 located outside the drying oven 1 can extend downward into a suitable container to facilitate the collection and utilization of excess moisture from the plastic products.

[0045] In this solution, the drying box 1 includes a blower, an electric heating wire, an air outlet, and a ventilation hole. The drying box 1 is the prior art in the existing published patent: CN202122609002.9 A drying device for plastic products, which will not be described in detail here.

[0046] In summary, by utilizing the above-mentioned technical solution of this utility model, plastic products are dried by placing them on the placement net 12. Moisture on the surface of the plastic products drips from the placement net 12 onto the bottom wall of the placement frame 11. Because the bottom wall of the placement frame 11 is inclined, the water flows through the first drain pipe 18 and the spring hose into the second drain pipe 19 and is discharged into the drying chamber 1. This allows the water to be collected and reused. Placing the plastic products on the placement net 12 within the placement frame 11 and starting the rotating motor 3 drives the positioning rod 4 to rotate. The rotation of the positioning rod 4 drives multiple first bevel gears 5 fixed thereon to rotate. Because the first bevel gears 5 mesh with the second bevel gears 8, they simultaneously drive multiple fixed shafts 6 to rotate. The convex block 7 rotates synchronously. When the convex block 7 rotates to the point where its protruding end faces upward, the convex block 7 exerts an upward pushing force on the placement frame 11, causing the placement frame 11 to move upward. The upward movement of the placement frame 11 causes the limiting slider 17, support block 16, limiting block 13, and sliding rod 14 to move upward synchronously. During this process, the spring 15 is compressed and deforms. When the convex block 7 rotates to the point where its protruding end faces downward, under the action of the release force of the spring 15, the limiting slider 17, support block 16, limiting block 13, sliding rod 14, and placement frame 11 are pushed downward synchronously. In summary, every time the convex block 7 rotates, it causes the placement frame 11 to move up and down once, thereby causing the plastic product to vibrate up and down once on the placement net 12. During this process, excess water on the plastic product can be shaken off.

[0047] Through the above technical solution, 1. by vibrating the plastic products up and down on the placement net 12, excess water on the plastic products can be shaken off, avoiding excessive water accumulation on the plastic products, facilitating the collection of excess water, and increasing air circulation under the plastic products during the up and down vibration process, thereby making the plastic products dry more evenly, accelerating the drying process, improving drying efficiency, and thus increasing the practicality of the plastic product drying device.

[0048] 2. Because the bottom wall of the placement frame 11 is inclined, water will enter the second drain pipe 19 through the first drain pipe 18 and the spring hose and be discharged into the drying box 1. This allows the water to be collected and reused, which is more environmentally friendly. It also avoids excess water in the drying box 1 from increasing the humidity in the drying box 1, thereby increasing the practicality of the plastic product drying device.

[0049] 3. By pulling the limiting block 13 upward, the limiting block 13 drives the sliding rod 14 and the support block 16 to move upward. Then, the placement frame 11 is pulled upward, causing the placement frame 11 to slide the protrusions 7 on the left and right sides upward until they no longer contact the limiting frame 9. At this time, the placement frame 11 is separated from the limiting frame 9. The placement frame 11 can then be pulled forward to pull it out of the drying chamber 1, thus removing the placement frame 11 from the drying chamber 1. This facilitates the cleaning and maintenance of the placement frame 11, making it more convenient and increasing the practicality of the plastic product drying device.
