Description

Technical Field

[0001] The utility model relates to the field of ABS material drying, in particular to drying equipment for ABS material processing. Background Art

[0002] ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It is also easy to process, the product size is stable, and the surface gloss is good. It is easy to paint and color. It can also be subjected to secondary processing such as surface metallization, electroplating, welding, hot pressing and bonding. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instruments and meters, textiles and construction. It is a thermoplastic engineering plastic with a wide range of uses. Before shaping the ABS material, the moisture in it needs to be dried before the next shaping step can be carried out. ABS is originally a resin material, and then processed into particles. The wet particles will cause scratches or bubbles on the product, which makes the items made of ABS material easy to crack or have a short service life. Utility Model Content

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] like Figure 1As shown, the present application discloses a drying device for processing ABS materials, which is composed of a drying box 1, a door frame 2, a rolling door 3, a heating device 4, a cross-shaped bracket 40, a heating wire 41, a fixing groove 42, an isolation plate 5, a large fan 6, an exhaust fan 7, a thermostat 8, a control panel 9, etc.;

[0020] like Figure 1 As shown in the figure, the softening point of ABS material is 101℃, the general melting point of ABS is about 170℃, and the decomposition temperature is 260℃; the adjustable range of injection molding temperature is large, and the general use temperature during injection molding is 180℃-240℃; due to the presence of a small amount of moisture in the rubber component, it can be dried at 80-90℃ for 1-2h during production; at the same time, due to the presence of rubber components, the thermal stability is poor and it is easy to decompose. During injection molding, the raw materials should not stay in the barrel for too long; the melt viscosity is larger than PS, but the gate and flow are generally good, and the product can be filled; the product is prone to static electricity, the surface is easy to absorb dust, the shrinkage rate is 5%, and the overflow value is 0.05mm.

[0021] like Figure 1 As shown, after the ABS material is produced into particles, there is still a small amount of moisture in it that needs to be dried. After injection molding, the undried particles will cause scratches or bubbles, reducing the service life of the product. The ABS material can be laid flat, loaded in a rectangular stainless steel tray, and then placed on a multi-layer steel frame and pushed into a drying box 1. A door frame 2 is provided at one end of the drying box 1. The ABS material can be pushed in from the door frame 2. The two sides of the door frame 2 are screwed to the rolling door 3. After the drying box 1 is full, the rolling door 3 is closed. The control panel 9 can control the operation of the entire mechanism.

[0022] like Figure 3 As shown, the heating device 4 includes a cross-shaped bracket 40, a heating wire 41 and a fixing groove 42. The cross-shaped bracket 40 is arranged at equal intervals vertically, and the two ends are vertically welded to the two sides of the inner wall of the drying box 1. The cross-shaped bracket 40 is fixedly arranged in the center cross, and a plurality of fixing grooves 42 are provided on it, so that the heating wire 41 is fixed on the fixing groove 42 to prevent it from falling off. A hollow chamber is formed between the isolation plate 5 and the drying box 1, and the heating device 4 and the large fan 6 can be installed. The purpose of the isolation plate 5 is to prevent the heating device 4 from being directly exposed to the outside, and it is in a grid style. The large fan 6 is installed behind the heating device 4 and close to the inner wall of the drying box 4. When the heating device 4 heats the surrounding air, the large fan 6 at the rear can blow the heated air to evenly distribute the hot air inside the entire drying box 1, ensuring that each grain of ABS material is fully dried.

[0023] like Figure 2As shown, during the drying process of the ABS material, water vapor will evaporate into the air. If the water vapor condenses too much, water droplets will appear. An exhaust fan 7 is installed at the upper end of the inner wall of the drying box 1 to extract the water vapor that has not formed water droplets out of the drying box 1 to prevent the ABS material from being dampened again. When the ABS material is dried for a specified time, the control panel 9 is used to stop the heating device 4 from supplying heat, and the large fan 6 can continue to operate to cool the ABS material inside the drying box 1 and then remove it.

[0024] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the utility model involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical scheme.
