In this embodiment, it also includes: an automatic deviation correcting machine 7, which is fixed on the frame 1 and connected with the film roll centering module 3 and the film supporting module 6. The automatic deviation correcting machine 7 swings to correct the position of the film roll 9. The automatic deviation correcting machine 7 adopts the existing one to correct the side of the film roll 9 to ensure that the film roll 9 is in the correct position. Through the coordinated work of the film feeding, centering, film supporting, film supporting, and film cutting modules, the full automation of the bagging of the cylinder 8 is realized, which reduces manual intervention and significantly improves production efficiency. The modules are connected with each other, and the process of film roll 9 from conveying to bagging is seamlessly connected, avoiding the pause and waiting time in traditional manual operation. The film roll centering module 3 and the automatic deviation correcting machine 7 ensure that the film roll 9 is always in the correct position to improve the accuracy.

[0020] Specifically, a plurality of film feeding modules 2 are installed at intervals on the frame 1, and the number can be set according to actual needs. The film roll rack 11 is installed on the frame 1, and the film roll 9 is manually installed on the film roll rack 11. The film roll 9 passes through the film feeding module 2 and the film roll centering module 3 passing above the frame 1 to ensure that the film remains centered and does not deviate, and then passes through another film feeding module 2 and an automatic deviation correcting machine 7. The automatic deviation correcting machine 7 prevents the film from deviating during the film conveying process and has an automatic adjustment and correction function. The film roll 9 is automatically drooped and transported to the film supporting module 6 through the automatic deviation correcting machine 7. The film supporting module 6 stretches the film, and at the same time, the film supporting module 5 straightens the film roll 9 to ensure that the film is in a vertical state and prevent the film from automatically falling down due to gravity after cutting. The system RFID reader identifies the size of the steel cylinder 8, calls out the PLC program corresponding to the size of the steel cylinder 8, and the film support module 6 pulls the roll film 9 to automatically move in the vertical direction of the steel cylinder 8.

The suction cup of the film support module 6 stops working and moves to the initial position.

[0021] Specifically, if Figures 2~4 As shown, in this embodiment, the film feeding module 2 includes: a first motor 21, a first synchronous belt 22, a pair of first synchronous wheels 23, a lower roller 24, an upper roller 25 and a clamping mechanism 26; the first motor 21 is fixed on the frame 1, and both ends of the lower roller 24 are rotatably set on the frame 1; a pair of first synchronous wheels 23 are respectively arranged at the output end of the first motor 21 and one end of the lower roller 24, and the first synchronous belt 22 is sleeved on the pair of first synchronous wheels 23; the upper roller 25 is arranged on the clamping mechanism 26, and the upper roller 25 is arranged above the lower roller 24 and parallel to the lower roller 24; the clamping mechanism 26 is relatively arranged on the frame 1, and the clamping mechanism 26 drives the upper roller 25 to approach the lower roller 24. During transportation, the roll film 9 is passed between the lower roller 24 and the upper roller 25, and the first motor 21 accurately transmits power to the lower roller 24 through the transmission of the first synchronous belt 22 and the synchronous wheel, thereby driving the roll film 9 to be transported, and the clamping mechanism 26 drives the upper roller 25 close to the lower roller 24 to ensure that the roll film 9 is evenly clamped, thereby improving the stability of transportation; through the cooperation of the upper and lower rollers 24, the roll film 9 is clamped and transported smoothly, thereby preventing the roll film 9 from slipping, deflecting or wrinkling during transportation.

[0022] Further, if Figure 3~4As shown, in this embodiment, the clamping mechanism 26 includes: a connecting rod 261, a crank 262 and a pair of clamping components; the pair of clamping components are relatively arranged on the frame 1; the connecting rod 261 passes through the pair of clamping components, and one end of the connecting rod 261 is connected to the crank 262; the clamping component includes: a connecting block 263, a sliding block 264 and a positioning block 265; the connecting block 263 is fixed on the frame 1, and the connecting block 263 is provided with a slide groove and a waist-shaped hole 2631 along its vertical direction; the sliding block 264 is slidably arranged in the slide groove, and the sliding block 264 is connected to the upper The end of the roller 25 is rotatably connected, and the positioning block 265 is fixed on the connecting block 263; the connecting rod 261 is rotatably connected to the sliding block 264 and passes through the waist-shaped hole 2631. The connecting rod 261 is placed on the positioning block 265. The connecting rod 261 is radially provided with a semicircular groove 2611, and the semicircular groove 2611 is opposite to the positioning block 265; when the crank 262 rotates, driving the connecting rod 261 to rotate until the semicircular groove 2611 is connected to the positioning block 265, the connecting rod 261 moves downward, driving the sliding block 264 and the upper roller 25 to approach the lower roller 24.

[0023] Specifically, the sliding block 264 slides up and down in the sliding groove of the connecting block 263 to ensure that the upper roller 25 can smoothly approach or move away from the lower roller 24. The waist-shaped hole 2631 provides a moving space for the connecting rod 261, and the positioning block 265 provides a reference; due to the effect of gravity, the connecting rod 261 is always in contact with the positioning block 265. When it is necessary to release the upper roller 25, the crank 262 is turned so that the semicircular groove 2611 is not in contact with the positioning block 265, that is, the cylindrical portion of the connecting rod 261 is The surface of the upper roller 25 is connected to the positioning block 265, and the height of the connecting rod 261 on the positioning block 265 is the height of its diameter, which drives the sliding block 264 and the upper roller 25 to move upward, so that the upper roller 25 is away from the lower roller 24; when the upper roller 25 needs to be pressed, the crank 262 is turned to make the semicircular groove 2611 engage with the positioning block 265, and the height of the connecting rod 261 on the positioning block 265 is the height of its radius, which drives the sliding block 264 and the upper roller 25 to move downward, so that the upper roller 25 is close to the lower roller 24. The height position of the positioning block 265 can be adjusted and installed according to actual use requirements.

The spring 266 provides a uniform and adjustable pressing force for the upper roller 25 through its elastic deformation, avoiding damage to the roll film 9 due to rigid compression, and can absorb the vibration and impact generated during the operation of the equipment to protect the roll film 9 and the roller from damage, so that the upper roller 25 can automatically adjust the pressing force according to the thickness of the roll film 9, ensuring that roll films 9 of different thicknesses can be stably transported.

[0025] Specifically, if Figure 5 As shown, in this embodiment, the film roll centering module 3 includes: a positive and negative threaded screw 31, a pair of first sliders 32, a pair of centering plates 33, a first guide rail 34 and a hand wheel 35; both ends of the positive and negative threaded screw 31 are rotatably connected to the frame 1, and a hand wheel 35 is installed at one end of the positive and negative threaded screw 31; the first guide rail 34 is fixed on the frame 1 and is parallel to the positive and negative threaded screw 31; a pair of first sliders 32 are respectively screwed on the positive thread area and the negative thread area of ​​the positive and negative threaded screw 31, and are slidably connected to the first guide rail 34; a pair of centering plates 33 are respectively fixed on a pair of first sliders 32, and the centering plates 33 are L-shaped, which can better fit the edge of the film roll 9; the film roll 9 is placed between the pair of centering plates 33; the hand wheel 35 rotates to drive the positive and negative threaded screw 31 to rotate, driving the pair of centering plates 33 to close or separate to adapt to the width of the film roll 9.

[0026] Specifically, if Figures 6 and 7As shown, in this embodiment, the film cutting module 4 includes: a second motor 41, a film cutting knife 42, an abutment platform 43, a pair of second synchronous wheels 44, a second synchronous belt 45, a transmission shaft 46, a pair of bearing seats 47, a pair of connecting rods 48 and a pair of second sliders 49; the second motor 41, the abutment platform 43 and a pair of bearing seats 47 are fixed on the frame 1; the two ends of the transmission shaft 46 are respectively connected to the pair of bearing seats 47 for rotation; a pair of second synchronous wheels 44 are respectively arranged on the output end of the second motor 41 and the transmission shaft 46; the second synchronous belt 45 is sleeved on the pair of second synchronous wheels 44; one end of a pair of connecting rods 48 is eccentrically hinged to the two ends of the transmission shaft 46, and the other ends of the pair of connecting rods 48 are hinged to a pair of second sliders 49, respectively, and the connecting rods 48 are perpendicular to the transmission shaft 46; the second sliders 49 are slidably set on the frame 1, and the film cutting knife 42 is fixed on the pair of second sliders 49, and the film cutting knife 42 and the abutment table 43 are arranged oppositely; the second motor 41 rotates, drives the transmission shaft 46 to rotate through the second synchronous belt 45 and a pair of second synchronous wheels 44, and then drives the second slider 49 and the film cutting knife 42 to approach or move away from the abutment table 43 through the connecting rod 48.

[0027] In this embodiment, the transmission shaft 46, the eccentrically hinged connecting rod 48 and the second slider 49 constitute a crank slider mechanism, which converts the rotational motion of the second motor 41 into the linear motion of the second slider 49, drives the film cutting knife 42 to approach the abutment table 43, and realizes the cutting of the roll film 9. The second motor 41 drives the transmission shaft 46 to rotate through the synchronous wheel and the synchronous belt mechanism to realize automatic cutting.

The abutment table 43 provides support for the roll film 9 to avoid deformation or displacement of the roll film 9 during the cutting process. Cutting can be performed according to the height specifications of the steel cylinder 8.

According to the height of the steel cylinder 8 in the program, the conveying of the roll film 9 is suspended, and the film cutting module 4 is activated to cut the size of the appropriate steel cylinder 8.

[0028] Specifically, if Figures 8 and 9As shown, in this embodiment, the film-supporting module 6 includes: a pair of second guide rails 61, a rack 62, a third motor 63, a first gear 64 and a film-supporting mechanism 65; the second guide rails 61 are vertically arranged on the frame 1, and the pair of second guide rails 61 are parallel to each other; the rack 62 is arranged between the pair of second guide rails 61 and is parallel to the second guide rails 61; the film-supporting mechanism 65 and the film-supporting module 5 are slidably arranged on the pair of second guide rails 61, and the second guide rails 61 ensure that the film-supporting mechanism 65 and the film-supporting module 5 move in a straight line during the movement to avoid deviation or tilting, and the film-supporting mechanism 65 is used to open the roll film 9; the third motor 63 is fixed on the film-supporting mechanism 65; the first gear 64 is arranged at the output end of the third motor 63 and meshes with the rack 62; the third motor 63 drives the first gear 64 to rotate, driving the film-supporting mechanism 65 to move along the second guide rail 61.

[0029] Further, if Fig. 9 As shown, in this embodiment, the film-supporting mechanism 65 includes: a fixed frame 651, a positive and negative tooth linear module 652, a pair of suction cup mounting plates 653 and a plurality of suction cups 654; the fixed frame 651 is slidably set on a pair of second guide rails 61; the third motor 63 and the positive and negative tooth linear module 652 are fixed on the fixed frame 651; a pair of suction cup 654 mounting plates 653 are respectively fixed on the two output ends of the positive and negative tooth linear module 652; a plurality of suction cups 654 are respectively arranged on a pair of suction cup 654 mounting plates 653, and the suction cup 654 mouths of the suction cups 654 face the roll film 9; the positive and negative tooth linear module 652 drives a pair of suction cup 654 mounting plates 653 to approach each other, driving a plurality of suction cups 654 to respectively adsorb and fix the opposite sides of the roll film 9, and the positive and negative tooth linear module 652 then drives a pair of suction cup 654 mounting plates 653 to separate, driving a plurality of suction cups 654 to support the roll film 9.

The fourth motor 52 installed on the supporting frame 51 is connected to the second gear 53. The film supporting module 5 is driven by the second gear 53 and the rack 62.
