Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic preparation, in particular to a rubber and plastic drying machine. Background Art

[0002] A rubber and plastic dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The rubber and plastic dryer vaporizes the moisture in the material (generally referring to water or other volatile liquid components) by heating to obtain solid materials with a specified moisture content. Some existing rubber and plastic dryers have been found to be stuck to the inner surface of the dryer body when the rubber and plastic are heated and evaporated. It is difficult to clean them up after a long period of accumulation, which affects the subsequent drying of the rubber and plastic. The sticky rubber and plastic will occupy a certain space, affecting the drying effect of other rubber and plastic, which is quite troublesome. Therefore, we propose a rubber and plastic dryer. Utility Model Content

[0003] A technical problem to be solved by the present application is: how to design a structure that can minimize the adhesion of rubber and plastic to the inner surface of the machine body without affecting the drying operation of the dryer.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-6 The utility model provides a technical solution: a rubber and plastic dryer, including a dryer body 1, a cylindrical drying chamber 2 is installed on the dryer body 1, and the drying chamber 2 itself heats and dries the rubber and plastic. This is the prior art, and also includes:

[0027] A rotating shaft 3, the rotating shaft 3 is rotatably arranged on the drying chamber 2;

[0028] The scraper plate 4 is slidably disposed in the drying chamber 2 and is in a ring shape and contacts the inner surface of the drying chamber 2;

[0029] The linkage assembly 5 is arranged on the drying chamber 2, and the rotating shaft 3 is rotated. The scraper plate 4 is driven by the linkage assembly 5 to slide back and forth along the inner surface of the drying chamber 2, and performs reciprocating motion, so as to continuously clean the inner surface of the drying chamber 2. Specifically, the linkage assembly 5 includes a shaft 51 rotatably arranged on the dryer body 1, a transmission pulley 52 is fixedly connected to the shaft 51, and a transmission pulley 52 is also fixedly installed on the rotating shaft 3. A transmission belt 53 is arranged on the two transmission pulleys 52, and the transmission belt 53 contacts and abuts against the two transmission pulleys 52 at the same time. A bidirectional screw rod 54 is fixedly arranged on the shaft 51, and a slider 55 is rotatably arranged on the bidirectional screw rod 54. The slider 55 is fixedly connected to the scraper plate 4, and two groups are arranged on the shaft 51, which are mirror-symmetrical, so that the scraper plate can be more stable when sliding and will not deviate from the set trajectory;

[0030] The motor 6 is started by program control. This part involves software control and is a prior art. The motor 6 is started to drive the rotating shaft 3 to rotate, and then drive the shaft 2 61 to rotate, thereby driving the stirring rake 62 to rotate, and then the stirring rake 62 stirs the rubber and plastic raw materials in the drying chamber 2. Stirring has two advantages. On the one hand, it accelerates the evaporation of the rubber and plastic water in the drying chamber 2, so that the heat in the drying chamber 2 can flow more effectively and the drying process can be carried out faster. On the other hand, the rubber and plastic raw materials are moved after stirring. Unlike the previous rubber and plastic that are motionless and receive heat and are easy to stick to the inner surface of the drying chamber 2, when the raw materials are stirred, the possibility of rubber and plastic sticking can be reduced;

[0031] When the motor 6 starts to drive the rotating shaft 3 to rotate, it also drives the transmission pulley 52 to rotate, thereby driving the transmission belt 1 53 to rotate, thereby driving another transmission pulley 52 to rotate, thereby driving the shaft 1 51 to rotate, thereby driving the bidirectional screw rod 54 to rotate, and then driving the slider 55 to slide along the bidirectional screw rod 54. When the slider 55 slides to one end of the bidirectional screw rod 54, it will slide in the opposite direction. This is the prior art. The sliding of the slider 55 drives the scraping plate 4 to slide on the inner surface of the drying chamber 2. At the same time, the shaft 1 51 can also play a role in limiting and guiding the scraping plate 4. Due to the characteristics of the bidirectional screw rod 54, the scraping plate 4 can reciprocate on the inner surface of the drying chamber 2 to scrape and clean the sticky rubber and plastic raw materials on the inner surface. The advantage is that the inner surface of the drying chamber 2 can be cleaned more conveniently.

[0032] A motor 6 is installed on the dryer body 1, and the output shaft of the motor 6 is fixedly connected to the rotating shaft 3. A second shaft 61 is fixedly provided on the rotating shaft 3. The second shaft 61 is located in the drying chamber 2, and the second shaft 61 is parallel to the horizontal plane. A stirring rake 62 is fixedly installed on the end of the second shaft 61 away from the rotating shaft 3 for stirring the rubber and plastic raw materials. The motor 6 can achieve both stirring and scraping effects, achieving multiple goals at one stroke.

[0033] There are multiple shafts 61, and there are also multiple stirring rakes 62, which correspond to the multiple shafts 61 respectively. The advantage of multiple shafts 61 is that the stirring range of the rubber and plastic is larger, which is more convenient for stirring the rubber and plastic, and it is easier to achieve the drying effect. The stirring range of the shaft 61 will not touch the scraping plate 4. The stirring of the shaft 61 and the scraping of the scraping plate 4 do not affect each other and will not interfere with the negotiation.

[0034] A shaft three 7 is fixedly connected to the rotating shaft 3, and the shaft three 7 is inclined to the ground. The shaft three 7 is located at the funnel-shaped bottom of the drying chamber 2 and is used to stir the bottom of the drying chamber 2. Because the bottom of the drying chamber 2 is funnel-shaped, and the straight shaft two 61 cannot stir the funnel-shaped bottom, an inclined shaft three 7 is added to stir the funnel-shaped bottom, and it can also prevent the rubber and plastic at the bottom from accumulating and not participating in the stirring.

[0035] A blower 8 is provided on the dryer body 1, and a pipe 81 is fixedly installed on the air inlet of the blower 8. The air inlet of the blower 8 faces the outside, and the air outlet of the blower 8 faces the inside of the drying chamber 2. Dust-proof nets 82 are installed on the air inlet and the outlet. The pipe 81 is fixedly connected to the dryer body 1. A dust-proof net 82 is provided in the pipe 81. The function of the dust-proof net 82 is to prevent dust from entering the drying chamber 2. The dust-proof net 82 is a prior art, and the dust-proof net 82 can be put away when not in use, and is used for discharging and blowing through the pipe 81. The pipe 81 can also form a channel for discharging. Hot air is blown into the drying chamber 2 through the blower 8 to accelerate the drying process. The wind can lift the rubber and plastic at the bottom, so that the rubber and plastic can participate in the mixing operation for many times, and the wind can also accelerate the loss of moisture.

[0038] A protective cover 9 is installed on the dryer body 1, and a transmission pulley 52 and a transmission belt 53 are placed in the protective cover 9 to protect the transmission pulley 52 and the transmission belt 53, thereby preventing the transmission pulley 52 and the transmission belt 53 from being damaged due to collision, reducing consumption, lowering costs, extending the use time, and improving work efficiency.
