Description

Technical Field

[0001] This invention relates to the field of Teflon tape stacking equipment technology, specifically a conveying device for stacking Teflon rolls. Background Technology

[0002] Teflon tape is widely used in many industries such as chemical, electronics, food processing, and machinery manufacturing due to its excellent properties such as high temperature resistance, corrosion resistance, non-stick properties, and good insulation. The market demand continues to increase. In the industrial production process of Teflon tape, the finished tape is rolled into a cylindrical roll, and then directly cut into rolls of tape of the corresponding width by equipment. After the finished tape rolls are slit, they are unloaded from the slitting equipment. The subsequent processes include orderly stacking, quantitative packaging, and external transportation. Currently, the industry's post-processing of slit Teflon tape rolls is prone to deviation during unloading and conveying, which affects the stacking accuracy of single rolls. After the tape rolls are unloaded from the slitting equipment, they are generally transferred by ordinary conveyor belts. Traditional conveying mechanisms lack dedicated guiding, limiting, and centering correction structures. Currently, most mainstream stacking equipment uses a single-ribbed material receiving structure. When the tape rolls in the ribbed accumulate to a specified quantity, the conveying and unloading processes must be suspended. The full ribbed material must be manually transferred and the empty ribbed material replaced. This results in frequent start-ups and shutdowns of the production line and significant breaks in the workflow. Manual stacking and quantitative packaging are costly and prone to errors. The single-ribbed stacking structure has poor stability and is prone to scattering during transfer. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 This invention provides a technical solution: a conveying device for stacking Teflon fabric rolls, comprising a conveying unit 1, a first guiding structure 2, a second guiding structure 3, a switching unit 4, and a stacking structure 5; the first guiding structure 2 is fixedly disposed on the conveying unit 1, the second guiding structure 3 is fixedly disposed on the left end of the conveying unit 1 and corresponds to the first guiding structure 2, the switching unit 4 is fixedly disposed on the left side of the conveying unit 1 and is located below the second guiding structure 3, and the stacking structure 5 is detachably disposed on the switching unit 4; the conveying unit 1 is used for belt conveying, the first guiding structure 2 is used for limiting and discharging materials, the second guiding structure 3 cooperates with the first guiding structure 2 to achieve centered conveying, and the switching unit 4 is used to drive multiple stacking structures 5 to switch positions and move, thereby facilitating the stacking and transfer of the fabric rolls.

[0022] As a preferred embodiment, the conveying unit 1 includes a base 11, two pairs of supports 12 and a conveyor belt assembly 13; one end of each of the two pairs of supports 12 is fixedly mounted on the upper wall of the base 11 and located at the four corners, wherein the two supports 12 on the left side are provided with trapezoidal telescopic grooves 6 near the top, and the conveyor belt assembly 13 is fixedly mounted on the other end of the supports 12.

[0023] More specifically, the conveying unit 1 has a simple overall structure and high support strength. It can stably support each functional component and complete the continuous conveying of the tape roll by relying on the conveyor belt assembly 13. It also uses the trapezoidal telescopic groove 6 on the left support 12 to make the position of the second guiding structure 3 adjustable. It can be flexibly adapted according to the tape roll specifications and material dropping requirements, thereby improving the overall adjustment flexibility and versatility of the equipment.

[0024] As a preferred embodiment, the first guiding structure 2 includes a pair of limiting frames 21, a first hydraulic cylinder body 22, a lifting frame 23, and a pair of guiding units 24. Both limiting frames 21 are concave, with one end of each limiting frame 21 symmetrically positioned on the upper wall of the base 11, near the left end of the base 11. The first hydraulic cylinder body 22 is fixedly mounted on the upper wall of the base 11, and is located between the pair of limiting frames 21. The lifting frame 23 is concave, with both ends of the lifting frame 23 movably penetrating through the limiting frames 21, and the middle of the lifting frame 23... Connected to the telescopic end of the first hydraulic cylinder body 22, the two ends of the lifting frame 23 are located on the front and rear sides of the conveyor belt assembly 13. A pair of guide units 24 are fixedly installed on both ends of the lifting frame 23 and are symmetrical to each other. By telescopically extending the first hydraulic cylinder body 22, the lifting frame 23 can be driven to move up and down along the limit frame 21, thereby synchronously adjusting the height of the two sets of guide units 24 fixed at both ends of the lifting frame 23 and arranged symmetrically. The two sets of guide units 24 are adjusted with the lifting frame 23 to a suitable height to fit the tape rolls of different thicknesses.

[0025] More specifically, relying on the main body 22 of the first hydraulic cylinder to drive the lifting frame 23 to rise and fall smoothly along the limit frame 21, the working height of the guide unit 24 can be flexibly adjusted according to the Teflon tape rolls of different outer diameters and specifications, and adapt to tape rolls of different thicknesses; the symmetrically arranged guide unit 24, together with the lifting structure, can stably complete the material limit and staggered single roll feeding, effectively avoiding the tape rolls from piling up and ensuring the feeding order. At the same time, the concave limit frame 21 can form a guiding constraint on the lifting frame 23, ensuring that the lifting action is smooth and the operation is reliable.

[0026] As a preferred embodiment, the guiding unit 24 includes a guiding frame 241, a first motor 242, a first pulley 243, a pair of second pulleys 244, a transmission belt 245, and a pair of guide arms 246. The guiding frame 241 has an E-shaped structure and three ends. The guiding frame 241 is fixedly mounted on one end of the lifting frame 23 and is located above the conveyor belt assembly 13. The first motor 242 is fixedly mounted on the left end of the guiding frame 241. The first pulley 243 is fixedly mounted on the drive end of the first motor 242. The pair of second pulleys 244 are movably mounted on the other two ends of the guiding frame 241 via axles 7. The second pulleys 244 are located to the right of the first pulleys 243, and the diameter of the second pulleys 244 is smaller than that of the first pulleys 243. The diameter of the pulley 243 is such that a pair of second pulleys 244 rotate in opposite directions. The two ends of the transmission belt 245 are respectively movably fitted onto the first pulley 243 and the right-side second pulley 244, and the middle of the transmission belt 245 contacts and guides the second pulley 244 located in the middle of the guide frame 241. The first motor 242 outputs power to drive the first pulley 243 to rotate, and the torque transmitted through the transmission belt 245 drives the middle second pulley 244 to rotate in the opposite direction, thereby driving the two guide arms 246 to swing back and forth in opposite directions. With the cooperation of two sets of symmetrically arranged guide units 24, one guide arm 246 swings out to stop and block the tape roll, and the other guide arm 246 retracts to complete the feeding. Through the staggered action, the Teflon tape roll is fed out one roll at a time.

[0027] More specifically, the conveying unit 24 adopts a simple transmission mechanism composed of pulleys and transmission belt 245, which has stable transmission and good synchronization of action. Relying on the second pulley 244 rotating in the opposite direction to drive the guide arm 246 to swing back and forth, it can accurately realize the cutting and stopping of the tape roll and the staggered single roll feeding, effectively avoiding the problems of multiple rolls of material accumulation and parallel conveying. The E-shaped conveying frame 241 has a compact layout, with all components assembled in a concentrated manner. The overall structure is simple and durable, with low operating noise, and can stably complete the material distribution operation for a long time, ensuring a uniform and orderly feeding rhythm.

[0028] As a preferred embodiment, the second guiding structure 3 includes a guide plate 31, a pair of insert rods 32, a pair of stop arms 33, and a pair of fastening bolts 34. The guide plate 31 is inclinedly disposed at the left end of the conveyor belt assembly 13, and the guide plate 31 fits into the conveyor belt of the conveyor belt assembly 13. The pair of insert rods 32 respectively movably pass through the telescopic grooves 6 of the bracket 12. One end of the pair of stop arms 33 is respectively fixedly disposed on one end of the insert rods 32, and the stop arms 33 are symmetrical to each other. The other end of the stop arms 33 is attached to the guide plate 31, and the fastening bolts 34 are screwed into it. A pair of brackets 12 are attached to the sidewalls, and fastening bolts 34 are tightened against the sidewalls of the insert rod 32. According to the tape roll specifications and the requirements of the dropping position, the insert rod 32 is slidable to adjust the spacing and position of the stop arm 33 on the guide plate 31. After the adjustment is completed, the fastening bolts 34 on the sidewalls of the brackets 12 are tightened, and the position is locked by using the bolt ends to tighten the insert rod 32. During the tape roll sliding, the stop arms 33 on both sides limit its left and right movement, and the inclined guide plate 31 guides the tape roll to slide smoothly down along the central trajectory to the lower stacking unit 53.

[0029] More specifically, the sliding insert 32 and trapezoidal telescopic groove 6 enable flexible adjustment of the position of the stop arm 33, which can be used to adapt to tape rolls of different widths and outer diameters, making it highly versatile. The inclined guide plate 31, together with the symmetrical stop arm 33, forms a central guide channel, which can effectively correct tape roll offset and ensure that the material is dropped vertically and accurately. At the same time, the overall adjustment operation is simple, the fastening bolt 34 has a reliable locking method, and can maintain the working position unchanged for a long time, ensuring that the dropping posture is regular and the stacking position is accurate.

[0030] As a preferred embodiment, the transposition unit 4 includes a base 41, a first electric slide rail 42, a second motor 43, and a turntable 44. One end of the base 41 is fixedly connected to the left end of the base 11. The first electric slide rail 42 is fixedly disposed in the middle of the upper wall of the base 41. The second motor 43 is fixedly disposed on the first electric slide rail 42 and can move left and right through the first electric slide rail 42. The turntable 44 has a cross-shaped structure, and slots 8 are provided in the middle of each of the four ends of the turntable 44. The middle of the turntable 44 is fixedly disposed on the drive end of the second motor 43.

[0031] More specifically, the first electric slide rail 42 enables fine-tuning of the turntable 44 position, ensuring precise matching between the receiving station and the unloading station. The cross-shaped turntable 44 can drive multiple stacking units 53 to rotate in a cycle without stopping the machine to replace the material rack. Only one replacement is needed, effectively ensuring production continuity. The overall layout is compact and the transmission action is stable. The multi-station rotation mode greatly improves the equipment's operating efficiency. The slot 8 structure also provides convenience for the disassembly and assembly of the stacking units 53.

[0032] As a preferred embodiment, the stacking structure 5 includes a second electric slide rail 51, a pair of clamping arms 52, and several stacking units 53. The second electric slide rail 51 is fixedly disposed between a pair of brackets 12 and located on the left side of the base 11. The second electric slide rail 51 is symmetrically provided with relatively movable second slide blocks. One end of each pair of clamping arms 52 is fixedly disposed on the second slide blocks of the second electric slide rail 51, and the clamping arms 52 are relatively movable. Several stacking units 53 are detachably inserted into the four ends of the turntable 44 and located at the slot 8. Several stacking units 53 correspond to the clamping arms 52 respectively.

[0033] More specifically, the second electric slide rail 51 drives the clamping arm 52 to achieve automatic opening and closing, with precise action coordination. It can automatically complete the state switching of the stacking unit 53 without manual intervention throughout the process. The stacking unit 53 adopts a plug-in detachable installation method, which is convenient for disassembly and assembly. Combined with the turntable 44 for multi-station rotation, it can continuously complete the tape roll stacking operation, effectively improving stacking efficiency. At the same time, the overall structure layout is reasonable, the action coordination is strong, and the operation is stable and reliable.

[0034] As a preferred embodiment, the stacking unit 53 includes a stacking frame 531, an insert block 532, a pair of expansion brackets 533, and several springs 534. The stacking frame 531 is rectangular, and the left and right side walls of the stacking frame 531 are staggered with insertion slots 9. The insert block 532 is fixedly disposed on the lower wall of the stacking frame 531, and the insert block 532 can pass through the slot 8 of the turntable 44. The pair of expansion brackets 533 are both L-shaped, with one end of each expansion bracket 533 movably embedded in the insertion slot 9 of the stacking frame 531, and the other end of each expansion bracket 533 can contact the clamping arm 52. The pair of expansion brackets 533 can extend and retract within the insertion slot 9, and cannot detach from the insertion slot 9. One end of each of the several springs 534 is equidistantly inserted into one end of each expansion bracket 533, and the other end of each spring 534 is... Contact the inner wall of the embedding groove 9; the clamping arms 52 move towards each other and squeeze the outer end of the expansion bracket 533, forcing the expansion bracket 533 to retract into the embedding groove 9 against the elastic force of the spring 534. At this time, the top of the stacking rack 531 is completely open, smoothly receiving the Teflon tape roll that slides down from above; when the stacking quantity reaches the standard, the clamping arms 52 move in opposite directions to release the squeezing, and the spring 534 rebounds to push the expansion bracket 533 outward. The L-shaped structure supports and limits the tape roll from the bottom and side to prevent the tape roll from sliding or tipping over, completing the stacking positioning. The clamping arms 52 can move relative to squeeze the expansion bracket 533, causing the expansion bracket 533 to embed into the embedding groove 9 of the stacking rack 531; the stacking rack 531 can be located below the middle of the left end of the guide plate 31 to receive the tape roll.

[0035] More specifically, the purely mechanical telescopic structure, which combines spring 534 and expansion bracket 533, allows for state switching via clamp arm 52, resulting in sensitive action response and stable operation. The L-shaped expansion bracket 533 serves both as support and limiter, ensuring secure positioning after stacking and effectively preventing tape from rolling and scattering the stack. Meanwhile, the plug-in block 532 is easy to install and disassemble, and the overall structure is simple, compact, and not easily damaged. It is suitable for continuous stacking operations and can also meet the needs of overall transportation and placement.

[0036] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0037] After the operation is started, the conveying unit 1 starts to run. The base 11 and the brackets 12 arranged at the four corners form an overall support frame. The telescopic groove 6 opened at the top of the left bracket 12 is used to adjust the position in conjunction with the second guiding structure. The conveyor belt assembly 13 mounted on the top of the bracket 12 continues to operate, smoothly conveying the Teflon tape roll forward. The tape roll moves with the conveyor belt assembly 13 to the first guiding structure area. A pair of concave limiting frames 21 are symmetrically fixed to the left end of the base 11. The main body 22 of the first hydraulic cylinder is installed between the two sets of limiting frames 21. The telescopic end of the main body 22 of the first hydraulic cylinder is connected to the concave lifting frame 23. The two ends of the lifting frame 23 move through the limiting frames 21. According to the specifications of the tape roll, the main body 22 of the first hydraulic cylinder drives the lifting frame 23 to rise and fall along the limiting frames 21, and synchronously adjusts the overall height of the guiding units 24 symmetrically arranged at both ends of the lifting frame 23. The guiding unit 24 uses the E-shaped guiding frame 241 as the mounting base. The first motor 242 is fixed to the left end of the guiding frame 241, and its driving end is connected to the first pulley 243. The other two ends of the guiding frame 241 are connected to the first pulley 243. A pair of second pulleys 244 are mounted on the axle 7. The diameter of the two second pulleys 244 is smaller than that of the first pulley 243 and they rotate in opposite directions. The transmission belt 245 is wrapped between the first pulley 243 and the right second pulley 244, and is guided by the middle second pulley 244. The first motor 242 outputs power, which drives the two sets of second pulleys 244 to rotate in opposite directions through the first pulley 243 and the transmission belt 245, thereby driving the guide arm 246 to swing back and forth in opposite directions. The two sets of guiding units 24 cooperate with each other and use the guide arms 246 to complete the stopping and releasing actions. One guide arm 246 blocks the tape roll, and the other guide arm 246 releases it, so as to realize the tape roll is discharged one roll at a time and prevent multiple rolls from being piled up for conveying. After leaving the first guide structure, the single roll of tape enters the area of ​​the second guide structure. The inclined guide plate 31 is seamlessly connected to the conveyor belt assembly 13 to receive the conveyed tape roll; two insert rods 32 are movably inserted into the telescopic groove 6 of the bracket 12 and can slide along the groove to adjust their position. The ends of the insert rods 32 are fixedly and symmetrically provided with stop arms 33, and the inner side of the stop arms 33 is attached to the surface of the guide plate 31; after adjusting the distance between the insert rods 32 and the stop arms 33 according to the size of the tape roll, the fastening bolts 34 on the side wall of the bracket 12 are tightened, and the position is locked by the bolts pressing the insert rods 32; the tape roll slides down along the inclined guide plate 31, and the stop arms 33 on both sides limit and correct its deviation to ensure that the tape roll falls vertically along the center line; The tape roll eventually falls onto the stacking unit 53 of the lower stacking structure 5. The stacking unit 53 is pre-fixed in the slot 8 of the turntable 44 of the switching unit 4 by inserting it into the bottom plug 532. The base 41 of the switching unit 4 is fixed to the left end of the base 11. The upper surface of the base 41 is equipped with a first electric slide rail 42. The second motor 43 is mounted on the first electric slide rail 42 and can move left and right with the slide rail. The drive end of the second motor 43 is connected to the cross-shaped turntable 44. Slots 8 are opened at all four ends of the turntable 44 for installing multiple stacking units 53. Before operation, the left and right positions of the second motor 43 and the turntable 44 can be finely adjusted by the first electric slide rail 42 so that the slots 8 and the reserved positions of the stacking units 53 can be removed from the clamping arm 52 for rotation and position adjustment. After each use, it is necessary to remove the clamping arm 42 and rotate to change position. In the stacking structure 5, the second electric slide rail 51 is fixed between the brackets 12. The slide rail is provided with a relatively movable second slide seat. A pair of clamping arms 52 are respectively fixed on the second slide seat. Before the tape roll falls, the second electric slide rail 51 drives the two sets of clamping arms 52 to move towards each other and squeeze the expansion frame 533 of the stacking unit 53. The rectangular stacking frame 531 of the stacking unit 53 has an embedding groove 9 on its left and right side walls. One end of the L-shaped expansion frame 533 is movably embedded in the embedding groove 9 and cannot be removed. Several springs 534 are installed at equal intervals between the embedding groove 9 and the expansion frame 533. When the clamping arms 52 squeeze the expansion frame 533, the expansion frame 533 overcomes the elastic force of the springs 534 and retracts into the embedding groove 9. The top of the stacking frame 531 is completely open and smoothly receives the falling tape roll. When the tape rolls in a single stacking unit 53 are stacked to a set number, the second electric slide rail 51 controls the clamping arms 52 to move in opposite directions, releasing the pressure on the expansion bracket 533. The spring 534 returns to its original position, pushing the L-shaped expansion bracket 533 outward from the embedded groove 9. The extended expansion bracket 533 supports and limits the entire stack of tape rolls from the side and bottom, preventing the tape rolls from sliding, tipping, or scattering. At this time, the switching unit 4 starts the first electric slide rail 42, which drives the turntable to disengage from the clamp arm 52. The second motor 43 drives the cross-shaped turntable 44 to rotate intermittently, turning the stacking unit 53 full of tape rolls out of the receiving station. At the same time, the empty stacking unit 53 is rotated to the bottom of the material drop to continue the receiving and stacking operation, realizing multi-station cyclical uninterrupted production. The operator can pull the stacking unit 53 out of the station out of the slot 8 of the turntable 44 to directly complete the transfer, placement and subsequent packaging of the whole stack of tape rolls. After that, the empty stacking unit 53 is put back into the slot 8. The whole set of equipment continuously cycles to complete the conveying and stacking operation of Teflon tape rolls.
