Description

Technical Field

[0001] This invention relates to the field of tape packaging technology, and more particularly to a continuous conveying device for Teflon tape packaging. Background Technology

[0002] Teflon tape, also known as fluoropolymer tape or PTFE tape, is a high-temperature resistant tape made of glass fiber as the base fabric, coated with polytetrafluoroethylene (PTFE) emulsion and laminated with silicone adhesive. Its applications are wide-ranging, covering food packaging heat sealing, plastic film processing, electronic and electrical insulation, and industrial roller protection. Fabric-reinforced products, due to their strengthened base material, are particularly suitable for high-strength applications such as sizing machine rollers and thermoplastic demolding.

[0003] Because the paper cores used in the tapes are wound to varying lengths, different specifications of Teflon tape products are created. To prevent the tapes from failing or becoming contaminated, they are usually conveyed to a packaging machine via a conveyor system. After being laminated by the packaging machine, they are protected using a plastic film.

[0004] Existing tape conveying devices consist of a feeder, a feeding mechanism, and a conveyor belt. The feeder organizes the tape into a uniform state and then sends it to the feeding mechanism, which arranges the tapes in sequence. Finally, the tapes are conveyed one by one by the conveyor belt. However, this type of device has significant drawbacks. Firstly, the two parallel clamps used for limiting the tapes in the feeding mechanism are fixed in position and cannot be adjusted in spacing, limiting the feeding to only one type of tape and making it difficult to meet the packaging needs of multiple tape sizes, resulting in poor practicality. Secondly, the tapes are prone to absorbing impurities during the forming process, causing surface protrusions and deformation. Existing devices lack corresponding quality inspection procedures, which can seriously affect product quality if the tapes are packaged directly. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies that cannot complete packaging and pre-packaging quality inspection of tapes of different specifications, the present invention aims to solve the technical problem of a continuous conveying device for packaging Teflon tapes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous conveying device for Teflon tape packaging, comprising a base plate, a first support base, and a second support base. The first and second support bases are respectively vertically installed on the left and right sides of the upper surface of the base plate. A material handling mechanism is installed on the upper surface of the first support base, and a limiting mechanism is installed on the upper surface of the second support base. The material handling mechanism sorts the tape and then conveys it to the limiting mechanism. The limiting mechanism allows the tape to be neatly arranged for feeding. A conveyor and a tape quality inspection mechanism are respectively installed at the front and rear ends of the left side of the limiting mechanism. The tape rotates under the cooperation of the conveyor and the tape quality inspection mechanism. A continuous conveying mechanism is installed laterally on the right side of the upper surface of the base plate, and the tape is continuously conveyed to the packaging machine through the continuous conveying mechanism.

[0007] Preferably, the material handling mechanism includes a tray that is inclinedly installed on the upper surface of the first support base, a first motor that is installed at the center of the lower surface of the tray, a rotatable bushing that is installed at the output end of the first motor, and a stop bar and a push plate that are respectively installed at the upper and lower ends of the outer wall of the bushing, with the stop bar and the push plate being staggered.

[0008] Preferably, the limiting mechanism includes a base mounted on the upper surface of the second support, with slides on both the left and right sides of the upper surface of the base, a driving assembly inside the base, and clamps mounted on the front and rear output ends of the top of the driving assembly. The left sides of the two clamps are respectively installed with the conveyor and the tape quality inspection mechanism. The clamps limit the tape and make the tape neatly arranged. A feeding assembly and two front-to-back positioning assemblies are respectively installed at the left and right ends of the base.

[0009] Preferably, the drive assembly includes a second motor installed on the left side of the base cavity. A screw is mounted on the output end of the second motor, and the other end of the screw is connected to the right inner wall of the base via a bearing. Movable plates are screwed onto both sides of the outer wall of the screw. Driven by the second motor, the screw can rotate clockwise or counterclockwise. The rotational force of the screw thread can drive the movable plates to move left or right. Two guide grooves are provided on the right side wall of the movable plate. Slide rods are installed on both sides of the base cavity along the front-back direction. Slide seats are installed at both ends of the outer wall of the slide rods, with the top of the slide seats installed at the bottom of the clamping plates. A guide post is installed on the left side of the slide seat, which inserts into the inner cavity of the guide groove. The mutual compression between the guide grooves and the guide post controls the spacing between the clamping plates, enabling the conveying of belts of different specifications.

[0010] Preferably, the two guide grooves are symmetrically and obliquely distributed on the moving plate.

[0011] Preferably, the feeding assembly includes a support plate installed on the top of the left side wall of the base, and the base, support plate, and tray are located on the same plane, allowing the tape to slide sequentially from the tray onto the support plate and the base. A feeding hole is provided on the right side of the upper surface of the support plate. A rotatable guide plate is installed at the right end of the inner cavity of the feeding hole via a pin. One end of a cylinder is installed at the bottom right end of the support plate via a pin, and the other end of the cylinder is connected to the bottom of the guide plate via a pin. The extension and retraction of the cylinder causes the guide plate to move up and down, controlling the opening and closing of the feeding hole. When the feeding hole is closed, the tape reaches the clamping plate to wait for packaging. When the feeding hole is open, unqualified tape is sorted out.

[0012] Preferably, the positioning component includes an extension plate installed on the right end of the clamping plate. A rotatable limiting plate is installed on the right end of the extension plate via a pin. One end of a tension spring is installed on the top of the limiting plate, and the other end of the tension spring is installed on the outer wall of the extension plate. Under the tension of the tension spring, the limiting plate is pulled to rotate, so that the limiting plate blocks the tape.

[0013] Preferably, the tape quality inspection mechanism includes a frame installed at the left end of the rear clamping plate. The left side of the frame is hollow. Two guide rods are inserted into the left rear end of the frame. A mounting base is installed at the front end of the guide rods. Rotatable rollers are installed on both the left and right sides of the front of the mounting base. A third motor that drives the rollers to rotate is installed on the upper surface of the mounting base. A conveyor belt is sleeved on the outer wall of the rollers. The tape rotates as it moves from left to right, driven by the conveyor belt and the conveyor. A squeezing component is provided in the inner cavity of the frame. If there are protrusions on the tape surface, it will cause the gap between the conveyor and the conveyor belt to increase. Under the condition of rack and pinion transmission, the cam rotates, thereby actuating the limit switch, thus providing a tape quality inspection function.

[0014] Preferably, the extrusion assembly includes a rotating shaft mounted on the right side of the inner cavity of the frame via a bearing. A cam and a gear are respectively mounted on the left end of the outer wall of the rotating shaft from left to right. The rotating shaft is driven to rotate by the gravity of the cam. A rack is mounted on the top rear side of the mounting seat and meshes with the gear. The mounting seat moves forward through the gear and rack transmission. A limit switch is mounted on the rear side of the inner cavity of the frame and is electrically connected to the cylinder.

[0015] Preferably, the limit switch and the cam are in the same plane.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a second motor to drive the screw to rotate clockwise or counterclockwise. The screw's thread rotation force drives the moving plate to move left and right. Under the mutual squeezing action of the guide groove of the moving plate and the guide post of the slide, the two opposing clamping plates can gradually move away or closer, thereby flexibly adjusting the tape limit width. This realizes the feeding function of tapes of different specifications, is suitable for the packaging needs of various tapes, and significantly improves the practicality and applicability of the device.

[0017] 2. This invention uses a third motor to drive the rollers to rotate, which in turn moves the conveyor belt. The belt rotates in conjunction with the conveyor, allowing for comprehensive inspection of its surface condition. When a protrusion on the belt comes into contact with the conveyor or belt, the protrusion squeezes the belt. Through gear and rack transmission, a cam rotates. When the cam triggers a limit switch, a cylinder drives a guide plate to swing downwards, causing defective belts to exit through the discharge hole. This adds a quality inspection step before packaging, effectively screening out defective products with protrusions or deformations, avoiding the negative impact of direct packaging on product quality, and significantly improving the quality of the final product.

[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] This invention provides a technical solution: a continuous conveying device for Teflon tape packaging, such as... Figures 1-9As shown, the system includes a substrate 1, a first support base 2, and a second support base 3. The first support base 2 and the second support base 3 are vertically installed on the left and right sides of the upper surface of the substrate 1, respectively. A material handling mechanism 4 is installed on the upper surface of the first support base 2, and a limiting mechanism 5 is installed on the upper surface of the second support base 3. The material handling mechanism 4 sorts the tape and then conveys it to the limiting mechanism 5. The limiting mechanism 5 arranges the tape neatly for feeding. A conveyor 6 and a tape quality inspection mechanism 7 are installed at the front and rear ends of the left side of the limiting mechanism 5, respectively. The tape rotates with the cooperation of the conveyor 6 and the tape quality inspection mechanism 7. A continuous conveying mechanism 8 is installed horizontally on the right side of the upper surface of the substrate 1. The continuous conveying mechanism 8 continuously conveys the tape to the packaging machine.

[0022] The material handling mechanism 4 includes a tray 41 that is inclinedly installed on the upper surface of the first support base 2. A first motor 42 is installed at the center of the lower surface of the tray 41. A rotatable bushing 43 is installed at the output end of the first motor 42. A stop bar 44 and a push plate 45 are respectively installed at the upper and lower ends of the outer wall of the bushing 43. The stop bar 44 and the push plate 45 are staggered. As the stop bar 44 and the push plate 45 rotate, the stop bar 44 first pushes the tape to lay it down, and then the push plate 45 pushes the tape to the discharge port to achieve the purpose of material handling.

[0023] As a preferred embodiment, the limiting mechanism 5 further includes a base 51 mounted on the upper surface of the second support 3. Slides 52 are provided on both the left and right sides of the upper surface of the base 51. A drive assembly 53 is provided in the inner cavity of the base 51. Clamping plates 54 are installed on the front and rear output ends of the top of the drive assembly 53. The left sides of the two clamping plates 54 are respectively installed with the conveyor 6 and the tape quality inspection mechanism 7. The clamping plates 54 limit the tape and make the tape neatly arranged. A feeding assembly 55 and two front-to-back positioning assemblies 56 are respectively installed on the left and right ends of the base 51.

[0024] As a preferred embodiment, the drive assembly 53 further includes a second motor 531 installed on the left side of the inner cavity of the base 51. One end of a screw 532 is mounted on the output end of the second motor 531, and the other end of the screw 532 is connected to the right inner wall of the base 51 via a bearing. Movable plates 533 are screwed to both sides of the outer wall of the screw 532. Driven by the second motor 531, the screw 532 can rotate clockwise or counterclockwise. The rotational force of the screw 532's thread can drive the movable plates 533 to move left or right. Two guide grooves 534 are formed on the right side wall of the movable plate 533, symmetrically and obliquely distributed on the movable plate 533. The inclined surfaces of the guide grooves 534 can... The guide post 537 is squeezed outward or inward, thereby increasing or decreasing the distance between the two clamping plates 54. Slide rods 535 are installed on both sides of the inner cavity of the base 51 along the front and back direction. Slide seats 536 are installed at both ends of the outer wall of the slide rod 535, and the top of the slide seat 536 is installed with the bottom of the clamping plate 54. The slide rod 535 is rectangular in shape to prevent the slide seat 536 from rotating when it moves. A guide post 537 that is inserted into the inner cavity of the guide groove 534 is installed on the left side of the slide seat 536. The distance between the two front and back opposing clamping plates 54 increases or decreases as the slide seat 536 moves, so as to achieve the limiting adaptation of tapes of different width specifications and ensure that the tapes always remain neatly arranged during the conveying process.

[0025] More specifically, when it is necessary to adapt to tapes of different widths, the second motor 531 starts and drives the screw 532 to rotate clockwise or counterclockwise. The rotational force of the screw 532 drives the moving plate 533 to move left or right. When the moving plate 533 moves, the inclined guide groove 534 squeezes the guide post 537, so that the front and rear slides 536 move outward or inward synchronously along the rectangular slide bar 535. The rectangular structure of the slide bar can prevent the slides from rotating, thereby driving the clamping plates 54 to move closer or further away synchronously, realizing the flexible adjustment of the spacing between the clamping plates 54 to adapt to tapes of different widths and ensure that the tapes are always neatly arranged during the conveying process.

[0026] As a preferred embodiment, the feeding assembly 55 further includes a support plate 551 installed on the top of the left side wall of the base 51, and the base 51, support plate 551, and tray 41 are located on the same plane, allowing the tape to slide down from the tray 41 onto the support plate 551 and the base 51 in sequence. A feeding hole 552 is provided on the right side of the upper surface of the support plate 551. A rotatable guide plate 553 is installed at the right end of the inner cavity of the feeding hole 552 through a pin. The guide plate 553 guides the tape and controls the direction of tape falling. A cylinder 554 is installed at the bottom right end of the support plate 551 through a pin. The other end of the cylinder 554 is connected to the bottom of the guide plate 553 through a pin. The extension and retraction of the cylinder 554 causes the guide plate 553 to move up and down, controlling the opening and closing of the feeding hole 552.

[0027] More specifically, when the tape quality inspection mechanism 7 detects a defective tape (such as surface protrusions or deformation), the cylinder 554 receives the signal and retracts, causing the guide plate 553 to rotate downwards, opening the discharge hole 552, and the defective tape is discharged from the discharge hole 552 under the action of gravity; when a qualified tape is detected, the cylinder 554 extends, pushing the guide plate 553 to rotate upwards, closing the discharge hole 552, and the tape slides along the guide plate 553 into the clamps 54 on the base 51 for limited arrangement.

[0028] As a preferred embodiment, the positioning component 56 further includes an extension plate 561 installed at the right end of the clamping plate 54. A rotatable limiting plate 562 is installed at the right end of the extension plate 561 via a pin. One end of a tension spring 563 is installed on the top of the limiting plate 562, and the other end of the tension spring 563 is installed on the outer wall of the extension plate 561. Under the tension of the tension spring 563, the limiting plate 562 is pulled to rotate, so that the limiting plate 562 blocks the tape. The left side of the limiting plate 562 is inclined, which has a centering effect on the tape and ensures that the tape can be carried away by the continuous conveying mechanism 8.

[0029] More specifically, under the tension of the tension spring 563, the limiting plate 562 maintains its initial state, blocking the tape in the clamp 54 and preventing it from slipping off prematurely. When the tray of the continuous conveying mechanism 8 inserts into the tape core, the tray pushes the tape to the right, and the tape squeezes the inclined surface of the limiting plate 562, causing the limiting plate 562 to overcome the tension of the tension spring 563 and rotate around the pin, releasing the tape. When the tape completely detaches from the limiting plate 562, the tension of the tension spring 563 drives the limiting plate 562 to reset, continuing to block subsequent tapes and ensuring that the tape can be taken away by the continuous conveying mechanism 8 in an orderly manner.

[0030] As a preferred embodiment, the tape quality inspection mechanism 7 further includes a frame 71 installed at the left end of the rear clamping plate 54. The left side of the frame 71 is hollow. Two guide rods 72 are inserted into the left rear end of the frame 71. A mounting seat 73 is installed at the front end of the guide rods 72. The guide rods 72 constrain the back-and-forth movement of the mounting seat 73. Rotatable rollers 74 are installed on both the left and right sides of the front of the mounting seat 73. A third motor 75 is installed on the upper surface of the mounting seat 73 to drive the rollers 74 to rotate. A conveyor belt 76 is sleeved on the outer wall of the rollers 74. When the tape moves from left to right, it rotates by the movement of the conveyor belt 76 and the conveyor 6. An extrusion assembly 77 is provided in the inner cavity of the frame 71. When the tape moves from left to right, it rotates around its own axis by the movement of the conveyor belt 76, so that its surface can be fully exposed.

[0031] More specifically, after the third motor 75 starts, it drives the roller 74 to rotate, which in turn drives the conveyor belt 76 to circulate in a clockwise or counterclockwise direction. The conveyor belt is conveyed from the feeding mechanism 4 to the area between the conveyor 6 and the conveyor belt 76. Under the combined action of the pushing force of the conveyor 6 and the friction force of the conveyor belt 76, the conveyor belt moves horizontally from left to right on the one hand, and rotates around its own axis on the other hand, so that all parts of the surface can be exposed to the inspection area, ensuring that no defects are missed.

[0032] As a preferred embodiment, the extrusion assembly 77 further includes a rotating shaft 771 mounted on the right side of the inner cavity of the frame 71 via a bearing. A cam 772 and a gear 773 are mounted from left to right on the left end of the outer wall of the rotating shaft 771. The rotating shaft 771 is driven to rotate by the gravity of the cam 772. A rack 774, meshing with the gear 773, is mounted on the top rear side of the mounting seat 73. The mounting seat 73 moves forward through the transmission between the gear 773 and the rack 774. A limit switch 775 is mounted on the rear side of the inner cavity of the frame 71 and is electrically connected to the cylinder 554. The limit switch 775 and the cam 772 are in the same plane. When the cam 772 rotates, it triggers the limit switch 775 as a tape detection signal. The extrusion assembly 77, acting as a quality inspection signal, combined with the sorting function of the unloading assembly 55, achieves automated quality inspection before tape packaging, effectively screening out unqualified products such as those with surface protrusions or deformation, ensuring the quality of subsequent packaged products.

[0033] More specifically, in the initial state, the cam 772 naturally droops due to its own weight, which drives the rotating shaft 771 and gear 773 to rotate clockwise. Through the meshing transmission of gear 773 and rack 774, the mounting base 73 is pushed forward along the guide rod 72, so that the conveyor belt 76 and the conveyor 6 clamp the belt together. Defect detection: When there are protrusions or deformations on the surface of the tape, the protrusions contact the conveyor belt 76 and generate a backward thrust, pushing the mounting base 73 to move backward along the guide rod 72, which in turn drives the rack 774 to move backward synchronously; the rack 774 drives the gear 773 to rotate counterclockwise, causing the rotating shaft 771 and the cam 772 to rotate counterclockwise synchronously, and the protruding end of the cam 772 gradually approaches the limit switch 775; Signal trigger: When the protruding end of the cam 772 triggers the limit switch 775, the limit switch 775 sends an electrical signal to the cylinder 554 to control the cylinder 554 to retract, so that the guide plate 553 of the feeding assembly 55 opens the feeding hole 552, and the unqualified tape is discharged from the feeding hole 552. Reset process: When the qualified tape passes through or the defective area is disconnected from the contact, the cam 772 resets under its own gravity, driving the mounting base 73 to move forward, and the conveyor belt 76 re-clamps the tape, waiting for the next inspection.

[0034] Working principle: Step 1: The tape is placed on the tray 41. The first motor 42 drives the bushing 43 to rotate, which in turn causes the stop bar 44 and the push plate 45 to rotate synchronously. The stop bar 44 first pushes down the upright tape, and then, with the help of the inclined surface of the tray 41, the push plate 45 moves the tape to the right, so that the tapes reach the conveyor 6 and the conveyor belt 76 one by one, thus realizing the sorting of the tapes. Step two: The third motor 75 drives the roller 74 to rotate, and the roller 74 drives the conveyor belt 76 to move. The cam 772 drives the gear 773 to rotate by gravity. Under the transmission conditions of the gear 773 and the rack 774, the conveyor belt 76 comes into contact with the conveyor 6. The belt rotates from left to right. If there are protrusions on the surface of the belt, the protrusions will squeeze the conveyor belt 76 to move backward, which will cause the rack 774 to move backward, so that the gear 773 drives the cam 772 to rotate in the opposite direction. The cam 772 touches the limit switch 775, the cylinder 554 shortens, the guide plate 553 rotates downward, and the discharge hole 552 opens, allowing the unqualified belt to fall from the discharge hole 552 for inspection before packaging. The qualified belt is sorted and arranged under the limiting action of the clamp 54. Step 3: The fourth motor 83 drives the sprocket 82 to rotate, causing the chain plate 84 to drive the tray 85 to move from left to right. The tray 85 is inserted into the tape yarn tube paper, dragging the tape from left to right. The limiting plate 562 rotates after being squeezed by the tape until the tape falls completely onto the tray 85. The tension spring 563 pulls the limiting plate 562 back to the initial position, blocking the tape inside the clamping plate 54 again, thereby allowing the tray 85 to continuously convey the tape to the packaging machine. Step four: When conveying tapes of different specifications, the second motor 531 drives the screw 532 to rotate clockwise or counterclockwise. Under the rotational force of the screw 532, the moving plate 533 moves to the left or right. Under the action of the inclined surface of the guide groove 534, the two guide posts 537 are squeezed and move outward or inward at the same time. The distance between the clamping plates 54 increases or decreases, and the tape limit width is adjusted. This is suitable for conveying tapes of different specifications.
