Description

Technical Field

[0001] This invention relates to the field of adhesive film conveying technology, and in particular to an adhesive film conveying mechanism and an adhesive film moisture drying system. Background Technology

[0002] Inside the drying oven, the film conveying system consists of chains, support rods, shafts, sprockets, bearings, and a power drive. During the drying process, the film undergoes both lateral and longitudinal shrinkage. To ensure sufficient longitudinal shrinkage allowance, the film conveying speed within the drying oven must be lower than the operating speed of the extrusion rollers; the ratio of this conveying speed to the extrusion roller speed should be 0.85. If the film conveying speed exceeds this ratio, i.e., the film is conveyed too quickly, it will inevitably result in a short dwell time and insufficient drying; if the conveying speed is too slow, the film will be heated for a longer time, also affecting product quality. Under normal operating conditions, the film's dwell time in the drying oven is generally 4-6 minutes, with a total travel distance of 123 meters. Therefore, the film conveying speed should be adjusted promptly according to changes in the operating speeds of the extrusion rollers, washing belt, etc.

[0003] Chinese patent application number CN201910409401.5; main classification number B65G15 / 48 discloses a conveyor belt device for a dryer, including an array of conveyor belts that are continuously conveyed from top to bottom inside 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 and inclined surfaces, and the two short sides are pivotally connected to two transmission chains near the vertical surface. The upper edge of the inclined surface of the metal frame at the upper working surface of the conveyor belt is fastened to the upper edge of the vertical surface of another metal frame to form a plane to support the material to be dried; in this way, when the conveyor belt runs to the output end, all the metal frames hang due to their own weight, and the hanging metal frames at the non-working surface form an open channel, and small falling objects will fall directly to the next conveyor belt.

[0004] However, the tension of the chain in its film conveying mechanism cannot be adjusted. If the chain is too loose or too tight, the running speed will be slow, the film will not stretch properly, and the film will easily fold horizontally. If the chain is too tight, the running speed will be too fast, the film will be overstretched, and it will easily fold in the longitudinal direction. All of these will affect the normal operation of the chain. Summary of the Invention

[0005] The purpose of this invention is to provide a film conveying mechanism and a film moisture drying system, which solves the problem of the inability to adjust the tension of the chain in the film conveying mechanism mentioned in the background art.

[0057] like Figures 1-5As shown in Embodiment 1, a film conveying mechanism includes a base 1, with several bases 1 arranged in a row. A frame 2 is mounted on each base 1, with two frames 2 arranged symmetrically. A film conveying channel is formed between the two frames 2. Each frame 2 includes a first horizontal plate 3, a second horizontal plate 4, a first vertical plate 5, and a second vertical plate 6. The first horizontal plate 3, first vertical plate 5, second horizontal plate 4, and second vertical plate 6 are connected end-to-end to form a frame structure. Two shaft holes 7 are provided on the first vertical plate 5, arranged symmetrically vertically. A first bearing is mounted on each shaft hole 7. A first shaft 9 is rotatably connected to a first bearing seat 8, and two symmetrically arranged first sprockets 10 are mounted on the first shaft 9. The first sprockets 10 are located within the film transmission channel. One of the first shafts 9 is connected to a first motor 11 via chain drive. Two through slots 12 are provided on the second vertical plate 6, arranged symmetrically vertically. A first tensioning mechanism 13 corresponding to the through slots 12 is mounted on the outer side of the second vertical plate 6. The first tensioning mechanism 13 includes two first ear seats 14. The first ear seat 14 is symmetrically arranged, with two first guide rods 15 slidably connected to each first guide rod 15. Each first guide rod 15 is slidably connected to a slide seat 16, the sliding direction of which is parallel to the transmission direction of the adhesive film. The slide seat 16 has a light hole 17, and a second bearing seat 18 is mounted on it. A second rotating shaft 19 is rotatably connected to the opposite second bearing seat 18, passing through the light hole 17 and the through groove 12. Each first ear seat 14 is threaded with an adjusting bolt 20, the head of which is connected to... The slide 16 is in contact; two symmetrically arranged second sprockets 21 are mounted on the second rotating shaft 19, and the second sprockets 21 are located in the film transmission channel; the second sprockets 21 are the same as the first sprockets 10, and the two second sprockets 21 and the two first sprockets 10 are meshed with a closed-loop support chain 22, which is used to transport the film; by setting the first tensioning mechanism 13, this application can adjust the tension of the support chain 22. When the tension is appropriate, the normal operation of the chain is ensured, and the problem of the film not stretching properly and folding horizontally is avoided; the problem of the film being overstretched and folding longitudinally is also avoided.

[0058] like Figure 5 As shown, as an optimization of Embodiment 1, the side walls of the first rotating shaft 9 and the second rotating shaft 19 are connected with rubber rollers 39. There are two rubber rollers 39, and the two rubber rollers 39 are tumblingly connected to the support shaft 32. By setting the rubber rollers 39, the conveying stability of the support shaft chain 22 can be improved.

[0059] like Figure 6As shown, as an optimization of Embodiment 1, the base 1 is composed of two vertical supports 23 and one horizontal support 24, forming an H-shaped structure; the vertical support 23 includes a base plate 25, a top plate 26, and a channel steel 27. The channel steel 27 is welded between the base plate 25 and the top plate 26, and a rib plate 28 is welded between the channel steel 27 and the base plate 25. The rib plate 28 is welded between the channel steel 27 and the top plate 26. The top plate 26 is used to install the frame 2.

[0060] like Figure 6 As shown, as an optimization of Embodiment 1, the frame 2 further includes a first support plate 29, a second support plate 30, and a third support plate 31. There are two first support plates 29, which are arranged horizontally. One first support plate 29 is located on the top surface of the first horizontal plate 3, and the other first support plate 29 is located on the bottom surface of the second horizontal plate 4 and connected to the top plate 26. There are two second support plates 30, which are arranged horizontally. One second support plate 30 is located on the bottom surface of the first horizontal plate 3, and the other second support plate 30 is located on the top surface of the second horizontal plate 4. There are two third support plates 31, one third support plate 31 is connected to the first vertical plate 5, and the other third support plate 31 is connected to the second vertical plate 6. The two third support plates 31 are connected to the two first support plates 29.

[0061] like Figure 7 and 8 As shown, and Figure 30 , Figure 31 , Figure 32 As shown, as an optimization of Embodiment 1, the support chain 22 includes a support shaft 32, a first chain plate 33, a second chain plate 34, and a bushing 35. Annular grooves 36 are formed at both ends of the support shaft 32. From the inside to the outside, the first chain plate 33, the second chain plate 34, the bushing 35, the second chain plate 34, and the first chain plate 33 are sequentially fitted onto the annular grooves 36. The first chain plate 33, the second chain plate 34, the bushing 35, the second chain plate 34, and the first chain plate 33 are rotatably connected to the support shaft 32. The bushing 35 is connected to the first sprocket 10 and the second sprocket. The 21-phase meshing mechanism has a pin hole 37 on the annular groove 36, and a cotter pin 38 is installed in the pin hole 37. The cotter pin 38 is used to limit the position of the outermost first chain plate 33. Several support shafts 32, several first chain plates 33, second chain plates 34, and bushings 35 form a closed-loop support chain 22. Such a support chain 22 can transport the adhesive film, and the spacing between adjacent support shafts 32 facilitates the flow of hot air. In addition, there are few places for dirt to accumulate on the support shafts 32, and the smoothness is good, so it will not contaminate the clean adhesive film and ensure the quality of the adhesive film.

[0062] like Figure 9As shown, as an optimization of the embodiment, considering that the middle section of the support shaft chain 22 will sag due to gravity, in order to improve the conveying stability of the support shaft chain 22, a guide plate 40 is fixed to the first horizontal plate 3 and the second horizontal plate 4 by bolts. The guide plate 40 is arranged horizontally and is located between the first sprocket 10 and the second sprocket 21. A U-shaped groove 41 is provided on the top surface of the guide plate 40. The U-shaped groove 41 is slidably connected to the first chain plate 33 and the second chain plate 34. According to the height of the support shaft 32, the top surface of the guide plate 40 can be set to a form where one side is high and the other side is low. By setting the guide plate 40, the support shaft chain 22 can be supported, ensuring the stable conveying of the support shaft chain 22. In conjunction with the first tensioning mechanism 13, the tension of the support shaft chain 22 can be adjusted to the optimal level.

[0063] like Figures 10-11 As shown, and Figure 33 As shown, as an optimization of Embodiment 1, considering the conveying stability of the support chain 22, a U-shaped frame 42 is installed on the third support plate 31. The forked portion of the U-shaped frame 42 is perpendicularly connected to the third support plate 31. A second tensioning mechanism 43 is connected to the straight portion of the U-shaped frame 42. There are two second tensioning mechanisms 43, which are arranged symmetrically. Each second tensioning mechanism 43 includes a first hinge seat 44, on which a screw tube 45 is hinged. The screw tube 45 has a cavity for accommodating a screw 47. A rotating nut 46 is rotatably connected to the screw tube 45, and a screw 47 is threadedly connected to the rotating nut 46. The outer end of the screw 47 is connected to a second hinge seat 48. A first spring seat 49 is hinged to the second hinge seat 48. A first spring 50 is installed on the first spring seat 49. A second spring seat 51 is connected to the free section of the first spring 50. A third hinge seat 52 is hinged to the second spring seat 51. A carrier 53 is installed on the third hinge seat 52. A tension wheel 54 is rotatably connected to the carrier 53 and meshes with the support shaft chain 22. A guide post 55 is slidably connected to the carrier 53. The free end of the guide post 55 is perpendicularly connected to the straight section of the U-shaped frame 42. By setting a screw 47, the tension of the tension wheel 54 and the support shaft chain 22 can be adjusted. The first spring 50 can absorb some of the vibration of the support shaft chain 22 during operation, making the support shaft chain 22 conveying more stably.

[0064] like Figures 12-15As shown, as an optimization of Embodiment 1, considering that the first spring 50 can provide a buffering effect, but may also cause bouncing and slight chain vibration, a push rod 56 is installed at the center of the first spring seat 49. A spring groove 57 is formed at the free end of the push rod 56. From right to left, a second spring 58, a closing ring 59, an intermediate body 60, and a nut head 61 are arranged sequentially on the spring groove 57. An intermediate body 60 is slidably connected to the spring groove 57. A first oil passage 62 and a second oil passage 63 are formed on the end face of the intermediate body 60. There are two first oil passages 62 arranged symmetrically, and two second oil passages 63 arranged symmetrically, with the second oil passages 63 located outside the first oil passages 62. The first and second oil passages 62 are located circumferentially around the intermediate body 60. The closing ring 59 is used for sealing. The outer diameter of the closing ring 59 in the first oil passage 62 is smaller than the area where the projection of the second oil passage 63 is located. A cylinder 64 is mounted on the second spring seat 51. An end cap 65 is mounted on the port of the cylinder 64. The end cap 65 is slidably connected to the push rod 56. The spring groove 57 of the push rod 56 is located inside the cylinder 64. The cylinder 64 is filled with hydraulic oil. The intermediate body 60 is slidably connected to the cylinder 64. The tension wheel 54 meshes with the support chain 22. The vibration of the support chain 22 is transmitted to the cylinder 64, and the cylinder 64 is compressed. When compressed, the closing ring 59 opens, and hydraulic oil passes through the two first oil passages 62 and the two second oil passages 63. When reset, the closing ring 59 closes, and hydraulic oil passes through the two second oil passages 63. Therefore, the cylinder 64 is easy to compress but difficult to stretch. This helps to absorb the energy of the first spring 50, thereby keeping the support chain 22 running smoothly.

[0065] like Figure 16 As shown, as an optimization of Embodiment 1, considering that the adhesive film needs to be fixed on the support chain 22 at its initial position to transport the adhesive film from one end to the other, a notch 66 is provided on a support shaft 32. The notch 66 is a quarter of the support shaft 32. A shaft 67 is rotatably connected to the notch 66, and an arc panel 68 is connected to the shaft 67. The arc panel 68 is concentric with the support shaft 32. A rubber head 69 is connected to the free end of the arc panel 68. The rubber head 69 is used to clamp the adhesive film. The serrated surface of the rubber head 69 contacts the notch 66. A third spring 70 is connected to the right angle of the notch 66. 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 with the notch 66, fixing the adhesive film on the support chain 22 and transporting the adhesive film from one end to the other.

[0066] like Figure 17 As shown, as an optimization of Embodiment 1, a plastic tube 71 is rotatably connected to the support shaft 32. The plastic tube 71 is in clearance fit with the support shaft 32, and the end of the plastic tube 71 is in clearance fit with the opposite first chain plate 33. By setting the plastic tube 71, it is convenient to clean up the charred particles later.

[0067] like Figure 18 As shown, as an optimization of Embodiment 1, considering that during the drying process of the adhesive film, due to the high temperature, the viscosity of the rubber decreases, and its adhesion to the support shaft 32 increases, a very small amount of rubber will adhere to these parts. If it remains at high temperature for too long, it will partially or completely lose its elasticity, or even carbonize, forming charred particles. Charred particles mixed in the rubber not only affect normal vulcanization, but also cause product defects. Larger charred particles protruding in the product can cause serious consequences such as water leakage and electrical leakage. During production, the support shaft 32 should be kept smooth and the rubber adhering to the support shaft 32 and other moving parts should be removed in time. The second horizontal plate 4 is equipped with a cleaning mechanism 72 arranged at equal intervals. The cleaning mechanism 72 is used to clean the charred particles on the support shaft chain 22 (plastic tube 71).

[0068] like Figure 19 As shown, as an optimization of Embodiment 1, an impurity tank 73 is installed on the base 1. The impurity tank 73 is used to collect the cleaned-up char particles. The impurity tank 73 is V-shaped, and a slag discharge pipe 74 is connected to the bottom surface of the impurity tank 73. An optical shaft 75 is rotatably connected inside the impurity tank 73. A spiral blade 76 is welded on the optical shaft 75. The spiral blade 76 is used to push the sintered particles in the impurity tank 73 and then discharge them from the slag discharge pipe 74. The optical shaft 75 is driven by a second motor 77. By setting the impurity tank 73, the cleaned-up char particles can be collected.

A drive gear 92 meshes with the first rack 86 and the second rack 89 and is driven by a fifth motor 93. The first cleaning roller 80 and the second cleaning roller 82 are located between opposing first chain plates 33. The first cleaning roller 80 and the second cleaning roller 82 are used to clean the burnt particles on the plastic tube 71 and drive the first rack 86 and the second rack 89 to move towards each other or away from each other through the drive gear 92, adjusting the distance between the first cleaning roller 80 and the support chain 22, and at the same time, the distance between the second cleaning roller 82 and the support chain 22 to ensure the best cleaning effect.

[0071] like Figure 23As shown in Embodiment 4, unlike Embodiment 1, the cleaning mechanism 72 includes a seventh bearing seat 94 and an eighth bearing seat 95. Two seventh bearing seats 94 are mounted on the frame 2 and are symmetrically arranged.

The free end of the third connecting rod 102 is hinged to another slider 96. One slider 96 is driven by a first telescopic rod 103. The tail end of the first telescopic rod 103 is connected to the carrier plate 98. The first telescopic rod 103 drives one slider 96 to move along the track 97. The second connecting rod 101 drives the first connecting rod 100 to rotate, and the first connecting rod 101 drives the third connecting rod 102 to rotate, so that the other slider 96 moves synchronously, realizing the reciprocating movement of the adjacent second cleaning rollers 82, resulting in good cleaning effect.

[0072] like Figure 24As shown in Embodiment 5, unlike Embodiment 1, the cleaning mechanism 72 includes a ninth bearing seat 104 and a tenth bearing seat 105. The tenth bearing seat 105 is mounted on the frame 2. There are two ninth bearing seats 104, symmetrically arranged. A first cleaning roller 80 is rotatably connected to each ninth bearing seat 104, and the first cleaning roller 80 is driven by a third motor 81. A T-shaped frame 106 is connected to each of the two ninth bearing seats 104. A U-shaped seat 107 is hinged to the vertical section of the T-shaped frame 106.

The first cleaning roller 80 and the second cleaning roller 82 are used to clean the burnt particles on the plastic tube 71. The second telescopic rod 108 drives the T-shaped frame 106 to rotate, and the distance between the first cleaning roller 80 and the support chain 22 is adjusted to ensure the best cleaning effect.

[0073] like Figure 25 and 26 As shown, in Embodiment Six, unlike Embodiments One through Six, considering that a gap needs to be left between the first cleaning roller 80 and the second cleaning roller 82 and the first chain plate 33 to prevent the brush bristles of the cleaning rollers from getting caught in the support shaft chain 22, a scraper ring 109 is slidably connected to the support shaft 32, and a fourth spring 110 is sleeved on the support shaft 32. The fourth spring 110 is located between the scraper ring 109 and the first chain plate 33 in an elastic connection manner, and the first cleaning roller 80 and the second cleaning roller 82 are between the two scraper rings 109; a straight shaft 111 is installed on the frame 2, and the straight shaft 111 is driven by a sixth motor 112; a cylindrical cam 113 is installed on the side wall of the straight shaft 111, and the cylindrical cam 113 has a curved groove 114; a straight shaft 111 is installed on the frame 2. The system is equipped with two guide rails 115, which are symmetrically arranged. Each guide rail 115 has a guide groove 116, and a slide table 117 is slidably connected to the guide groove 116. A ball head 118 is connected to the slide table 117, and the ball head 118 is slidably adapted to the curved groove 114. Guide rods 119 are connected to both sides of the slide table 117, and guide sleeves 120 are slidably connected to the side walls of the guide rods 119. The guide sleeves 120 are connected to the guide rails 115. A push plate 121 is installed on the guide rods 119. The push plate 121 is used to push the scraper ring 109. The scraper ring 109 can clean the burnt particles in the gap between the first cleaning roller 80, the second cleaning roller 82 and the first chain plate 33, making the cleaning more comprehensive and further improving the cleaning effect.

[0074] like Figure 27As shown in Embodiment Seven, unlike Embodiment One, the cleaning mechanism 72 includes an eleventh bearing seat 122, on which a third cleaning roller 123 is rotatably connected. The third cleaning roller 123 is driven by a seventh motor 124, and the eleventh bearing seat 122 is driven by a reciprocating screw mechanism 125. The reciprocating screw mechanism 125 is mounted on the frame 2. The reciprocating screw mechanism 125 drives the third cleaning roller 123 to move on the support chain 22, and at the same time, it cleans the charred particles on the plastic tube 71.

[0075] like Figure 28 and Figure 29 As shown, a film moisture drying system using the above-mentioned film conveying mechanism is further proposed, including several drying ovens 126. This application takes five drying ovens 126 as an example. Each drying oven 126 consists of an upper box 127 and a lower box 128. The upper box 127 is located on the first support plate 29 on the top surface of the first horizontal plate 3, and the lower box 128 is located on the second support plate 30 on the bottom surface of the first horizontal plate 3. An upper partition plate 129 is installed between adjacent upper boxes 127, and a lower partition plate 130 is installed between adjacent lower boxes 128. The bottom surface of the lower box 128 is located above the second horizontal plate 4. The box drying process of the film involves the drying medium (i.e., hot air) transferring heat to the wet film. 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. Therefore, 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 acts as both a heat carrier and a moisture carrier. It should be noted that a necessary condition for drying is that the pressure of water vapor on the surface of the film must be greater than the partial pressure of water vapor in the hot air. The greater the pressure difference, 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 process combining heat and mass transfer, and the drying rate is governed by both the heat transfer rate and the mass transfer rate. Furthermore, the lower horizontal section of the support shaft chain 22 is located outside the oven 126 and cools naturally during operation, reducing the adhesion between the support shaft 32 and the film.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
