[0026] In the prior art, the general film strip 600 is transported and cut in a horizontal manner after being conveyed by the casting conveyor. This method requires the film strip 600 to be transported and handed over in order to replace the conveyor line. In addition, in order to avoid pulling the film strip 600, a transition or buffer station is required, which increases the complexity of the device. In addition, the existing film strip 600 production method also has the problem of inaccurate cutting accuracy, and the cut film strip 600 has wrinkles.

[0027] For this purpose, refer to Figure 1The embodiment of the present application provides a film tape production device, which specifically includes a cast film conveying section 100, a turnover conveying section 200 and a stacking section 500. The cast film conveying section 100 is used to convey the film tape 600. The conveying position of the turnover conveying section 200 is higher than the cast film conveying section 100 and the stacking section 500. The conveying position of the turnover conveying section 200 is set to a conveying height higher than the cast film conveying section 100 and the stacking section 500. Compared with the horizontal transportation and cutting method adopted in the prior art, there is no need to transport and hand over the film tape 600, which avoids pulling the film tape and reduces the setting of workstations. Simple processing can avoid the complexity of the device and reduce the modification cost. A cutting mechanism is provided between the turnover conveying section 200 and the stacking section 500, and the cutting mechanism is used to cut the film strip 600 to a fixed length. A first transition piece 310 is provided at the outflow end of the turnover conveying section 200, and the first transition piece 310 is connected to the cutting mechanism. The first transition piece 310 is used to adjust the shape and position of the film strip 600. Specifically, the first transition piece 310 is provided between the cutting mechanism and the turnover conveying section 200, which is conducive to correcting the film strip 600 before cutting, so as to avoid irregular shape and position deviation before cutting. , the situation of smooth conveying is improved, and the cutting accuracy is improved; a second transition piece 320 is arranged between the cutting mechanism and the stacking part 500, and the second transition piece 320 is used to guide the cut film tape 600 to the stacking part 500, wherein the second transition piece 320 is arranged between the cutting mechanism and the stacking part 500, and the cut film tape 600 is guided and adjusted by the second transition piece 320, so as to reduce the probability of wrinkles or partial stacking of the cut film tape 600, so that the cut film tape 600 can be smoothly conveyed to the stacking part 500.

[0028] Specifically, the casting conveying section 100 includes a circulating casting steel belt, and a stripping knife 130 is provided at a position of the casting steel belt near the turnover conveying section 200. The stripping knife 130 is used to separate the film belt 600 from the casting steel belt. A rotary encoder 120 for collecting the rotation speed of the driven wheel 110 is provided on the driven wheel 110 of the casting steel belt, so that the conveying speed of the casting steel belt can be calculated according to the rotation speed of the driven wheel 110.

[0029] The turnover conveying part 200 includes a circulating conveying belt. An electrostatic elimination mechanism 210 is arranged above the position of the conveying belt close to the first transition piece 310. The electrostatic elimination mechanism 210 is used to eliminate static electricity of the film belt 600 conveyed on the conveying belt.

[0030] In actual work, the conveying speed of the cast steel belt should be consistent with the conveying speed of the conveyor belt, so that the film belt 600 can be kept in a state of not being stretched or wrinkled.

[0031] In some embodiments, the conveying surface 311 of the first transition piece 310 is provided with a plurality of air holes for conveying airflow. The first transition piece 310 is preferably made of ceramic. In actual operation, the first transition piece 310 is connected to the positive pressure airflow, and the positive pressure airflow is blown to the surface of the conveying surface 311 through the air holes, so that the film belt 600 floats on the conveying surface 311. By adjusting the airflow rate, the probability of the film belt 600 sticking to the first transition piece 310 is effectively reduced, so that the passing film belt 600 has a regular shape, a small position deviation, and is not adsorbed on the conveying surface 311 of the first transition piece 310.

[0032] In some embodiments, Figure 2 As shown, the conveying surface 311 is inclined relative to the horizontal plane. Furthermore, the angle C formed by the conveying surface 311 and the horizontal plane is set to 75° to 80°. According to the test, if the angle C formed by the conveying surface 311 and the horizontal plane is less than 75°, the flotation effect is unstable, and the film belt 600 may not droop smoothly due to adsorption effects such as static electricity; if the angle C formed by the conveying surface 311 and the horizontal plane exceeds 80°, the conveying state of the film belt 600 is unstable and fluttering may occur. When the angle C is between 75° and 80°, the film belt 600 can achieve stable drooping, and the conveying process is more stable.

[0033] In some embodiments, the end of the circulating conveying part 200 close to the stacking part 500 has a conveying wheel 201, the end of the first transition piece 310 close to the conveying wheel 201 is lower than the center of the conveying wheel 201 and faces the arc segment 201a of the stacking part 500, and the extension line of the conveying surface 311 is tangent to the conveyor belt. Figure 2 As shown, here it means that the end of the first transition piece 310 is close to Figure 2 The lower right side of the conveying wheel 201 shown enables the first transition piece 310 to better receive the stably drooping film strip 600, thereby avoiding wrinkles or stacking of the film strip 600 due to interference.

[0034] like Figure 2 As shown, the cutting mechanism includes a fixed first cutter 410 and a second cutter 420 that can move toward the first cutter 410. The film strip 600 is cut by the cooperation between the first cutter 410 and the second cutter 420, wherein the end line 311a of the conveying surface 311 close to the end of the first cutter 410 and the cutting edge 411 of the first cutter 410 are in the same plane in the vertical direction. With the above design, after being conveyed by the first transition piece 310, the normally drooping film strip 600 accurately falls onto the cutting edge 411 of the first cutter 410 without causing interference, thus avoiding bending, wrinkling or stacking due to interference, and making the cutting size and precision more accurate.

[0035] In some embodiments, the carrying surface 323 of the second transition piece 320 is provided with a plurality of blowing holes 322 for conveying airflow, and the central axis of the blowing hole 322 is not perpendicular to the carrying surface 323. Figure 3 As shown, the blowing hole 322 is cut obliquely toward the end of the second transition piece 320 close to the stacking part 500, wherein the angle E between the blowing hole 322 and the carrying surface 323 is set to 25° to 35°. If the angle E between the blowing hole 322 and the carrying surface 323 is too small, it is difficult to process, and if it is too large, the film strip 600 is easily blown away from the carrying surface 323 to cause deformation. The aperture of the blowing hole 322 is less than 1 mm. Specifically, the second transition piece 320 has a buffer cavity 321, and the blowing hole 322 is connected to the buffer cavity 321. The airflow passing through is distributed through the buffer cavity 321. After the positive pressure air flow is connected, the air flow rate is adjusted, and the air flow is distributed through the buffer cavity 321. The blowing hole 322 will blow out a small airflow in the forward and downward direction, so that the film strip 600 will not be wrinkled or adsorbed when passing through the carrying surface 323, and can be smoothly transported downward to the stacking part 500.

[0036] In some embodiments, the second transition piece 320 is inclined relative to the horizontal plane, and the angle D between the second transition piece 320 and the horizontal plane is set to 55° to 65°. According to experiments, if the angle D between the second transition piece 320 and the horizontal plane is less than 55°, the inclination of the second transition piece 320 will be smaller, and the sliding speed of the film tape 600 on the carrying surface 323 will be slightly slower. During the transportation of the film tape 600, there is a probability that the film tape 600 will be piled up, causing the front part of the film tape 600 (here refers to the end of the cut film tape 600 close to the stacking part 500) to be wrinkled; if the angle D between the second transition piece 320 and the horizontal plane is greater than 65°, the film tape 600 will fall quickly after being cut by the cutting mechanism, and there is a probability that the rear part of the cut film tape 600 (here refers to the end of the cut film tape 600 close to the cutting mechanism) will be wrinkled. Setting the included angle D between the second transition piece 320 and the horizontal plane to 55° to 65° can effectively reduce the occurrence of wrinkles or stacking of the membrane tape 600 reaching the carrying surface 323 .

[0037] In some embodiments, a limiting wheel 330 is arranged above the receiving end and the output end of the carrying surface 323. The receiving end here refers to a section of the carrying surface 323 close to the cutting mechanism, and the output end refers to a section of the carrying surface 323 close to the stacking part 500. The distance between the limiting wheel 330 and the carrying surface 323 is adjustable to adapt to film tapes 600 of different thicknesses. The setting of the limiting wheel 330 can effectively guide the conveying direction of the film tape 600.

[0038] The collection and stacking of the existing cut film strips 600 are all done manually, which is inefficient. At the same time, due to the low position accuracy of manual stacking, a large part of the irregular area around the edges needs to be cut off after stacking, resulting in material waste.

[0039] To this end, the stacking unit 500 of the embodiment of the present application can effectively solve this problem, wherein, for example Figure 4 As shown, the stacking portion 500 includes a perforated conveyor belt 510, a first suction cup 520 and a second suction cup 530, the first suction cup 520 and the second suction cup 530 are arranged in the perforated conveyor belt 510, the conveyor belt of the perforated conveyor belt 510 is provided with through holes, the first suction cup 520 and the second suction cup 530 are arranged between the two ends of the perforated conveyor belt 510, and the first suction cup 520 and the second suction cup 530 are close to the conveying surface of the conveyor belt, so that the negative pressure provided by the first suction cup 520 and the second suction cup 530 can make the cut film tape 600 adsorbed on the perforated conveyor belt 510. Specifically, after the cut film tape 600 is transported to the perforated conveyor belt 510, it is carried forward by the perforated conveyor belt 510. When passing through the area of ​​the first suction cup 520, it is stably adsorbed on the perforated conveyor belt 510 by the negative pressure suction provided by the first suction cup 520. When it is transported to the area just reaching the second suction cup 530, the second cutter 420 in the cutting mechanism moves quickly to cut the film tape 600. The perforated conveyor belt 510 speeds up and transports the just cut film tape 600 forward quickly, so that the rear end of the film tape 600 will not fall due to gravity and cause wrinkles. At this time, the limiting wheel 330 limits the film tape 600 from being taken away from the second transition piece 320 in a state of rapid movement, thereby keeping the entire film tape 600 flat and improving the stability of transportation. Among them, the first suction cup 520 and the second suction cup 530 are independent. The first suction cup 520 needs to keep the suction force all the time, and the second suction cup 530 needs to turn off the suction force when the conveying mechanism 540 sucks the film tape 600. The cut film tape 600 is transported to the storage bin 550 through the conveying mechanism 540 to realize the automatic storage of the film tape 600.

[0040] Assemble the various parts of the present application according to the positions in the drawings, and connect them to the casting conveyor section 100 of the steel belt casting machine. Adjust the program parameters to make the linear speeds of the turnover conveyor section 200 and the casting conveyor section 100 equal. Adjust the position and angle of the first transition piece 310 so that the position where the upper end of the first transition piece 310 intersects with the turnover conveyor section 200 is lower than the center of the conveyor wheel 201 of the conveyor belt, and the conveying surface 311 of the first transition piece 310 is basically tangent to the conveyor belt of the turnover conveyor section 200. Adjust the position of the first cutter 410 so that the lower right edge (i.e. Figure 2 The end line 311a in the middle) and the cutting edge 411 of the first cutter 410 are located in the same plane in the vertical direction. The positions of the second transition piece 320 and the limiting wheel 330 are adjusted so that the lower right edge (i.e. Figure 2 The end line 311a in the vertical direction is located between the second transition piece 320 and the limiting wheel 330 close to the first transition piece 310. The position of the conveying mechanism 540 is adjusted so that the conveying mechanism 540 is located directly above the second suction cup 530 when the material is taken.

[0041] When the production device of the present application is used: the film strip 600 peeled by the peeling knife 130 is manually pulled onto the turnover conveyor 200, and then passes through the first transition piece 310 and passes between the first cutter 410 and the second cutter 420, and slides into the second transition piece 320 by the weight of the film strip 600. The second cutter 420 is started to cut off the irregular part of the end of the film strip 600, and then the device automatically runs to carry out the subsequent cutting and conveying process of the film strip 600.

[0042] The present application can realize stable conveying, slicing and stacking of the film strip 600 while the steel strip is cast at a uniform speed without stopping, thereby reducing the labor input and improving the film cutting accuracy and stacking quality.

[0043] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
