Description

Technical Field

[0001] The present invention relates to the technical field of film conveying, and in particular to a film conveying mechanism and a film moisture drying system. Background Art

[0002] Inside the drying oven, the film's transport system consists of chains, support rods, shafts, sprockets, bearings, and a power drive. During the drying process, the film shrinks both horizontally and vertically. To allow for sufficient longitudinal shrinkage, the film's transport speed within the drying oven must be lower than the speed of the squeeze rollers. The ratio of transport speed to squeeze roller speed is 0.85. If the film's transport speed exceeds this ratio, i.e., the transport speed is too fast, the film's dwell time will be short, resulting in incomplete drying. If the transport speed is too slow, the film will be heated for a prolonged period, which will also affect product quality. Under normal operating conditions, the film's residence time within the drying oven is typically 4-6 minutes, with a total travel distance of 123 meters. Therefore, the film's transport speed should be adjusted promptly based on the speeds of the squeeze rollers, washing belt, and other components.

[0003] The Chinese patent with application number CN201910409401.5 and main classification number B65G15 / 48 discloses a dryer conveyor belt device, including an array conveyor belt device for continuous conveying from top to bottom in the dryer; a plurality of metal frames integrally formed or welded with mesh are connected to form a conveyor belt, the two long sides of the metal frame are set as vertical surfaces and inclined surfaces, and the two short sides are pivotally connected to two transmission chains at the near-vertical surfaces. The upper edge of the inclined surface of the metal frame at the active surface above the conveyor belt is buckled with the upper edge of the vertical surface of another metal frame to form a plane to carry the objects to be dried; in this way, when the conveyor belt runs to the output end, all the metal frames are formed into a hanging shape due to their own weight, and an open channel is formed at the hanging metal frame on the non-active surface, and small dropped objects will fall directly to the next conveyor belt.

[0004] However, the tension of the chain of its film conveying mechanism cannot be adjusted, which can be too loose or too tight. When the chain is too loose, the running speed is slow, the film is not stretched, and the film is easy to fold horizontally; when the chain is too tight, the running speed is too fast, the film will be over-stretched, and it is easy to fold longitudinally, which will affect the normal operation of the chain.

The end cover 65 is slidably connected to the push rod 56, and the spring groove 57 of the push rod 56 is located in the cylinder 64. The cylinder 64 is filled with hydraulic oil, the intermediate body 60 is slidably connected to the cylinder 64, and the tensioning wheel 54 is engaged with the fulcrum chain 22 for operation. The vibration of the fulcrum chain 22 is transmitted to the cylinder 64, and the cylinder 64 is compressed. When compressed, the closed ring 59 opens, and the hydraulic oil passes through the two first oil passages 62 and the two second oil passages 63. When reset, the closed ring 59 is closed, and the hydraulic oil passes through the two second oil passages 63. Therefore, the cylinder 64 is easily compressed and difficult to be stretched, which helps to absorb the energy of the first spring 50, thereby keeping the fulcrum chain 22 running smoothly.

[0065] like Figure 16 As shown, as an optimization of Example 1, considering that the film needs to be fixed on the support chain 22 when it is in its initial position, so that the film can be transported from one end to the other, a notch 66 is provided on a support shaft 32, and the notch 66 is a quarter of the support shaft 32.

A third spring 70 is connected at a right angle to the notch 66, and the third spring 70 is connected to the inner side of the arc panel 68. By setting the third spring 70, the arc panel 68 is clamped by the notch 66, so that the film is fixed on the support chain 22, and the film can be transported from one end to the other.

If it is exposed to high temperature for too long, it will partially or completely lose its elasticity, or even carbonize, forming burnt particles; the burnt particles mixed in the rubber will not only affect normal vulcanization, but also cause product defects. Larger burnt particles will appear in the product, which may cause serious consequences such as water leakage and electric leakage; during production, the support shaft 32 should be kept smooth and the rubber adhered to the moving parts such as the support shaft 32 should be removed in time; the second horizontal plate 4 is equipped with cleaning mechanisms 72 arranged at equal intervals, and the cleaning mechanisms 72 are used to clean the burnt particles on the support shaft chain 22 (plastic tube 71).

[0075] like Figure 28 and Figure 29 As shown, further, a film moisture drying system using the above-mentioned film conveying mechanism is proposed, including a plurality of drying ovens 126. This application takes 5 drying ovens 126 as an example. The drying oven 126 consists of an upper box 127 and a lower box 128. The upper box 127 is arranged on the first support plate 29 on the top surface of the first horizontal plate 3, and the lower box 128 is arranged on the second support plate 30 on the bottom surface of the first horizontal plate 3. Upper partitions 129 are installed between adjacent upper boxes 127, and lower partitions 130 are installed between adjacent lower boxes 128. The bottom surface of the lower box 128 is located above the second horizontal plate 4. The box-type drying process of the film is that the drying medium (i.e., hot air) transfers heat to the wet film, and the moisture on the surface of the wet film vaporizes and diffuses into the hot air through the surface air film; at the same time, due to the vaporization of moisture on the surface of the material, a humidity difference is generated between the inside and the surface of the film, so the moisture inside the material diffuses to the surface in the form of gas or liquid, and finally enters the hot air in the form of gas. Clearly, hot air is both a heat carrier and a moisture carrier. It should be noted that a prerequisite for drying is that the water vapor pressure on the film surface must be greater than the partial pressure of water vapor in the hot air. The greater the pressure difference between the two, the faster the drying process. Therefore, the hot air should promptly remove the vaporized water vapor to maintain a certain mass transfer driving force. Thus, drying is a combined process of heat and mass transfer, with the drying rate being governed by both the heat and mass transfer rates. Furthermore, the lower horizontal section of the support shaft chain 22, located outside the oven 126, cools naturally during operation, reducing adhesion between the support shaft 32 and the film.
