Technical Field
[0001] This utility model belongs to the technical field of drying devices, and more specifically, it relates to a drying device for preparing polyurethane resin. Background Technology
[0002] Polyurethane resin is a polymer material formed by the polymerization of isocyanates and hydroxyl compounds. It possesses a variety of excellent properties, such as high strength, durability, elasticity and flexibility, chemical resistance, abrasion resistance, weather resistance, and lightweight. Depending on the foaming process, application, and chemical structure, polyurethane resins can be classified into several types. During the preparation of polyurethane resin, drying is typically required to remove moisture and residual solvents from the raw materials, preventing them from affecting the chemical reaction and product quality, ensuring a high degree of polymerization and accurate functional group molar ratio, and guaranteeing a smooth processing flow to obtain a polyurethane resin product with excellent properties.
[0003] Based on the above, the inventors have discovered the following problems: Currently, when drying polyurethane resin, it is usually placed on a drying rack and then put into a drying oven for drying. However, this drying method requires placing the polyurethane resin during drying and removing it after drying. During this time, the drying oven is not working, resulting in low work efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drying device for the preparation of polyurethane resin, in order to achieve a more practical purpose. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a drying device for polyurethane resin preparation, thereby solving the problem of low drying efficiency in current drying devices.
[0006] The purpose and effect of this utility model's drying device for preparing polyurethane resin are achieved by the following specific technical means:
[0007] A drying apparatus for preparing polyurethane resin includes a drying chamber with movable doors on both sides. The doors are movable. A first track is installed inside the drying chamber, and second tracks are installed on both sides of the drying chamber. A first placement rack is installed in the first track, and a second placement rack is installed in one of the second tracks. A connecting plate is installed on the second track on the same side as the second placement rack via a drive assembly. The connecting plate is connected to the second placement rack, and the first placement rack is connected to the second placement rack via connecting components.
[0008] Furthermore, the drive assembly includes a mounting plate mounted on one of the second track surfaces, a motor mounted on the surface of the mounting plate, a threaded rod mounted through the output end of the motor through the mounting plate, the threaded rod passing through a movable block and connecting to the outer shell of the drying chamber, a set of guide rods mounted between the mounting plate and the drying chamber, the guide rods passing through the movable block, and a connecting plate mounted on the top of the movable block.
[0009] Furthermore, the connecting component includes a connecting rod and a set of fixing plates, the fixing plates being installed on both sides of the connecting rod.
[0010] Furthermore, the fixing plate is connected to the first placement frame, the second placement frame, and the connecting plate by bolts.
[0011] Furthermore, the cabinet doors are secured together by latches.
[0012] Furthermore, the surface of the cabinet door is provided with grooves.
[0013] Furthermore, the surface of the drying oven is coated with an anti-rust coating.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This invention utilizes a track, a placement rack, and a drive assembly. Upon opening the drying chamber door, polyurethane resin is placed on the second placement rack. The motor, via a threaded rod and a moving block, moves the connecting plate, causing the second placement rack to move into the drying chamber while the first placement rack remains outside. The chamber door has slots for matching the connecting rod. During drying, the next batch of resin can be placed on the first placement rack. After drying, the motor drives the replacement of the first and second placement racks, removing the dried resin and placing new resin in, thus improving work efficiency. Attached Figure Description

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0028] Example:
[0029] As attached Figure 1 To be continued Figure 5 As shown:
[0030] This utility model provides a drying device for polyurethane resin preparation, including a drying box 1. Movable doors 2 are installed on both sides of the drying box 1. The doors 2 are movable. A first track 3 is installed inside the drying box 1, and second tracks 4 are installed on both sides of the drying box 1. A first placement rack 5 is installed in the first track 3, and a second placement rack 6 is installed in one of the second tracks 4. A connecting plate 8 is installed on the second track 4 on the same side as the second placement rack 6 via a drive assembly 7. The connecting plate 8 is connected to the second placement rack 6, and the first placement rack 5 is connected to the second placement rack 6 via connecting components 9.
[0031] The drive assembly 7 includes a mounting plate 701 mounted on the surface of one of the second tracks 4. A motor 702 is mounted on the surface of the mounting plate 701. A threaded rod 703 is mounted through the output end of the motor 702 through the mounting plate 701. The threaded rod 703 passes through the moving block 704 and is connected to the outer shell of the drying chamber 1. A set of guide rods 705 is installed between the mounting plate 701 and the drying chamber 1. The guide rods 705 pass through the moving block 704. A connecting plate 8 is mounted on the top of the moving block 704.
[0032] The connecting component 9 includes a connecting rod 901 and a set of fixing plates 902, with the fixing plates 902 installed on both sides of the connecting rod 901.
[0033] With the coordinated use of the first track 3, the second track 4, the first placement rack 5, the second placement rack 6, and the drive assembly 7, the doors 2 on both sides of the drying chamber 1 are first opened. Then, the polyurethane resin to be dried is placed on the second placement rack 6. The motor 702 is then started. The start of the motor 702 drives the threaded rod 703 to rotate, which in turn drives the moving block 704 to move. The guide rod 705 can limit the movement of the moving block 704. The movement of the moving block 704 drives the connecting plate 8 to move, which in turn drives the second placement rack 6 to move via the connecting component 9. The movement of the second placement rack 6, in turn, drives the first placement rack 5 to move via the connecting component 9. When the second placement rack 6 is located on the first track 3 inside the drying chamber 1, the first placement rack 5 is located on the second track outside the drying chamber 1. 4. Then close the door 2 and start the drying chamber 1 for drying. Note that the surface of the door 2 is provided with a groove that matches the connecting rod 901. The connecting rods 901 in the two connecting parts 9 are located on the same axis. While drying, place the polyurethane resin to be dried on the first placement rack 5. When the polyurethane resin on the second placement rack 6 is dried, open the door 2 and start the motor 702, thereby moving the second placement rack 6 to the outside of the drying chamber 1 and moving the first placement rack 5 to the inside of the drying chamber 1 for drying. At this time, the dried polyurethane resin on the second placement rack 6 can be removed, and then the polyurethane resin to be dried can be placed. Through the above design, the next polyurethane resin to be dried can be placed while the drying chamber 1 is drying, which greatly improves the efficiency of the work.
[0034] The fixing plate 902 is connected to the first placement frame 5, the second placement frame 6 and the connecting plate 8 by bolts 10.
[0035] The cabinet doors 2 are fixed together by latches 11.
[0036] The surface of the box door 2 is provided with grooves.
[0037] The surface of the drying oven 1 is coated with an anti-rust coating.
[0038] The use of an anti-rust coating can extend the service life of the drying oven 1.
[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
