Description

An automatic winding device for columnar fiber filament products and a packaging method for sponge film. Technical Field

[0001] This invention belongs to the field of reinforced fiber production technology, and in particular relates to an automatic winding device for columnar fiber filament sponge film and a packaging method. Background Technology

[0002] As people demand higher quality of life, lightweight and high-strength materials are gradually replacing metal materials in people's lives. Reinforcing fibers such as glass fiber are widely used in building materials, clean energy and aerospace as important basic materials for industrial strengthening.

[0003] While fiber-reinforced materials can be mixed with resins as reinforcing agents to form excellent plastic materials, giving them higher impact toughness, insulation properties, flexural tensile strength, and creep resistance, the fibers themselves are relatively hard and brittle, making them prone to breakage and fuzzing after impacts, especially during transfer and transportation, which can affect subsequent product manufacturing processes.

[0004] Therefore, columnar fiber filament products are formed through drawing and crimping processes. During the production process, the packaging process must not only package qualified products, but also take certain measures to ensure that the products can be used normally when they reach the customer.

[0005] Currently, to ensure products are not damaged during transportation, columnar fiber precursors are typically wrapped with a protective film and then further wrapped with a 3-5mm thick sponge film. This sponge film is purchased pre-made; during use, the double-sided adhesive is manually peeled off at both ends, wrapped around the outside of the product, and the adhesive is pressed to ensure a tight seal. This packaging process is labor-intensive and inefficient. Summary of the Invention

[0006] To reduce worker workload and labor intensity, this application proposes an automatic winding device and packaging method for columnar fiber filament products using sponge film. This method enables automatic sponge film replenishment, adhesive application, feeding, wrapping, and pressing, thereby improving the automation of the packaging process for columnar fiber filament products. The above-mentioned technical objective of this invention is achieved through the following technical solutions:

[0007] On one hand, the present invention provides an automatic winding device for columnar fiber raw material sponge film, including a sponge film supply mechanism, a sponge film cutting machine and a sponge film feeding mechanism, which respectively cuts the whole roll of sponge film to obtain rectangular sponge film and transfer rectangular sponge film;

[0008] The double-sided tape applicator attaches a layer of double-sided tape to each end of a rectangular sponge film.

[0009] The sponge film smoothing and pressing mechanism adheres double-sided adhesive to the raw yarn;

[0010] It also includes the overall equipment frame, on which the sponge film feeding mechanism, the double-sided adhesive applicator mechanism, and the sponge film smoothing and pressing mechanism are respectively mounted.

[0011] Preferably, the sponge film feeding mechanism is used to transfer the cut rectangular sponge film. Starting from the incoming material direction, it includes a transfer panel and a temporary storage panel, with a sponge film gripper above the temporary storage panel. Panel slides for controlling the movement of the transfer panel are located below both sides of the short side of the transfer panel. A pair of rectangular openings are located in the middle of the transfer panel, each containing a vacuum suction plate. The surface of the vacuum suction plate is flush with the surface of the transfer panel, and a suction plate slide is located below the vacuum suction plate. The vacuum suction plate has evenly distributed small holes connected to compressed air, which, when compressed, can suction the rectangular sponge film. The vacuum slide uses a cylinder to move the vacuum suction plate, thereby moving the rectangular sponge film a certain distance so that it can be gripped by the sponge film gripper.

[0012] Furthermore, pressure fingers are provided on both sides of the short side of the transfer panel for pressing the rectangular sponge film. The pressure fingers include inner pressure fingers and outer pressure fingers. The space between the inner and outer pressure fingers is a central groove, which is the working area of ​​the double-sided adhesive applicator, providing working space for the operation of the double-sided adhesive applicator. The sponge film gripper is used for gripping and transferring the rectangular sponge film. The root of the sponge film gripper is provided with a vertically movable gripper slide, which is mounted on the feeding slide.

[0013] Furthermore, the transfer panel is provided with bending limits on both sides to prevent misalignment of the sponge film.

[0014] Preferably, there is a pair of double-sided tape application mechanisms, which are arranged symmetrically above the sponge film feeding mechanism with respect to the center line of the long side of the rectangular sponge film. They are used to apply a layer of double-sided tape to each end of the rectangular sponge film. Each mechanism includes an application sliding seat fixed to the overall frame of the equipment. The application sliding seat is equipped with an application cylinder that moves in a vertical direction. The application cylinder is connected to a mounting plate. The mounting plate is equipped with a double-sided tape traction wheel for actively traction of the double-sided tape.

[0015] Double-sided tape mounting wheel is used to fix and install double-sided tape. A guide wheel is set below the double-sided tape mounting wheel, and a tape-cutting mechanism is set below the guide wheel. The tape-cutting mechanism completes the cutting of double-sided tape by the cutting and retracting action of the blade without damaging the release paper. A shaft of the adhesive roller is fixed below the tape-cutting mechanism, and a rotatable adhesive roller is sleeved on the shaft. The adhesive roller is used to press the tape and the sponge film tightly.

[0016] The tensioning wheel, located between the double-sided tape traction wheel and the adhesive roller, is used to ensure that the double-sided tape is in a taut state.

[0017] Furthermore, the double-sided tape application mechanism also includes a hot air blowing device mounted on the overall frame of the equipment.

[0018] The sponge film smoothing and pressing mechanism includes a raw yarn storage base and a pressing mechanism on each side of the storage base. Each pressing mechanism includes a sponge film pressing roller, a roller rocker arm, a pressing roller, and a roller rocker arm slide. The pressing roller includes a roller with its central axis along the feeding direction of the rectangular sponge film. The roller is mounted on the overall frame of the equipment through a lifting structure. The roller rocker arm slide is mounted on the overall frame of the equipment through a slide structure. Together with the roller rocker arm and the rocker arm cylinder, it forms a crank rocker mechanism. The sponge film pressing roller is located at the end of the roller rocker arm and moves its position with the swing of the roller rocker arm.

[0019] Furthermore, the raw filament storage base has a structure that is low in the middle and high on both sides, with nylon pads provided on the two inclined surfaces to facilitate the storage of raw filaments.

[0020] Infrared sensors are respectively installed above the raw yarn storage base, transfer panel, and temporary storage panel of the sponge film smoothing and pressing mechanism to detect whether there are objects above them.

[0021] The top crossbeam of the overall frame of the equipment is equipped with a raw yarn transfer mechanism. Two sliding frames are slidably mounted above the crossbeam, each with a sliding arm that slides vertically. A yarn-holding gripper is located at the bottom of each sliding arm. Both the sliding frames and arms are movable under the drive of a driving mechanism. The yarn-holding gripper can move in both horizontal and vertical directions. The yarn-holding gripper can transfer the raw yarn at three stations. The front yarn-holding gripper can pick up the columnar fiber raw yarn from the protective film winding station and transfer it to the sponge film smoothing and pressing mechanism. The rear yarn-holding gripper can pick up the wound raw yarn and transfer it to the discharge station.

[0022] Preferably, the system also includes a sponge film support mechanism. This mechanism is fixed to the ground by a support base. A cantilever shaft is mounted on the top of the support base via a bearing structure. The cantilever shaft is rotatable and is an air-expansion shaft structure, enabling the winding and unwinding of the entire roll of sponge film. A limit plate and a limit ring are respectively provided at the root and outer end of the cantilever shaft. A clamp is provided on the side of the limit plate facing the support base to restrict the position of the limit plate 13 on that side. The limit ring is fixed to the end of the cantilever shaft by tightening screws, thus adapting to rolls of sponge film of different widths. A bearing seat for the cantilever shaft is also provided on the top of the support base, and a safety guard is installed on its outer side to prevent mechanical damage.

[0023] In another aspect, the present invention provides a packaging method, comprising the following steps:

[0024] Step 1: The infrared sensor on the raw yarn storage base of the sponge film smoothing and pressing mechanism detects whether there is sponge film above it; if no sponge film is detected, a sponge film material request will be issued.

[0025] Step 2: The sponge film feeding mechanism moves to the waiting station after the sponge film cutting machine, where the sponge film cutting machine supplies the cut rectangular sponge film.

[0026] The sponge film moves forward under the rotation of the feed roller of the sponge film cutting machine, and the cantilever shaft of the sponge film support mechanism and the roll of sponge film rotate under the traction of force; after the sponge film feed length reaches the set distance of the sponge film cutting machine, the feed roller stops rotating, the cutter moves, and cuts out a rectangular sponge film.

[0027] The rectangular sponge film will fall onto the transfer panel. The vacuum suction plate will pick up the rectangular sponge film and move a certain distance towards the sponge film winding station under the action of the suction plate slide. After it is in place, the pressure finger will move downward to press the rectangular sponge film, and the vacuum suction plate will stop sucking air and reset.

[0028] Step 3: The main actuator of the double-sided tape applicator moves towards the rectangular sponge film under the drive of the applicator sliding seat. During this process, the hot air device preheats the tape as needed. After the applicator sliding seat is in place, the applicator cylinder actuates, and the mounting plate moves downward until the applicator roller presses against the rectangular sponge film. Subsequently, the applicator sliding seat moves in the opposite direction, and the double-sided tape traction wheel rotates simultaneously. The double-sided tape detaches from the release paper under the action of the adhesive bond with the sponge film and the pressure of the applicator roller. After traveling half the distance, the blade of the tape-cutting mechanism actuates, cutting the tape without... Damaging the release paper, the adhesive sliding seat and double-sided adhesive traction wheel continue to operate until all the double-sided adhesive tape is adhered to the surface of the rectangular sponge film, and the adhesive cylinder and adhesive sliding seat reset; then, the transfer panel moves towards the sponge film winding station under the drive of the panel slide until it approaches the temporary storage panel, then the sponge film gripper of the feeding mechanism opens and moves towards the sponge film, and closes to clamp the long side of the rectangular sponge film after it is in place, and moves in the opposite direction to transfer the rectangular sponge film to the top of the raw yarn storage base, while the sponge film pressure roller presses down on the two short sides of the rectangular sponge film;

[0029] While the sponge film grippers of the feeding mechanism are transferring the material, since there is no material at the temporary storage panel and the transfer panel is in a waiting state, a material request will be sent to the sponge film cutting machine until the sponge film grippers of the feeding mechanism transfer the new rectangular sponge film to the temporary storage panel.

[0030] If both the raw yarn storage base and the temporary storage panel detect the rectangular sponge film, the transfer panel will also send a request to the sponge film cutting machine. That is, the sponge film cutting will only stop after the conditions of the raw yarn storage base, the temporary storage panel and the transfer panel are met.

[0031] Step 4: When the raw yarn storage base detects the sponge film, the raw yarn transfer mechanism, under the action of the sliding frame moving laterally, the sliding arm moving longitudinally, and the yarn clamping claws, grabs the columnar fiber raw yarn from the protective film winding station to the raw yarn storage base of the sponge film smoothing and pressing mechanism. Then the sponge film pressure roller is released, and the raw yarn storage base sinks under the action of the base slide. The rocker arm slide on one side moves towards the raw yarn position, and the roller rocker arm rotates upward under the action of the rocker arm cylinder. The sponge film pressure roller contacts the sponge film and rolls on the side of the raw yarn under the action of the roller rocker arm until it rolls to the top of the raw yarn. At the same time, the tape is stuck to the upper side of the raw yarn. Then it is reset. Then the same action is performed on the other side to stick the double-sided tape firmly on the other side.

[0032] After completion, the raw yarn transfer mechanism, through the lateral movement of the sliding frame, the longitudinal movement of the sliding arm, and the gripping action of the yarn clamping claw, picks up the wound raw yarn and moves it to the discharge station. The sponge film winding action is then complete.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. This application provides an automatic winding device for sponge film of columnar fiber raw material products. The device can realize automatic feeding, adhesive application, feeding, winding, wrapping and pressing of sponge film, which helps to reduce labor intensity, reduce the procurement cost of sponge film and increase enterprise profits.

[0035] 2. Traditional sponge film requires double-sided adhesive peeling and sponge film wrapping. In contrast, this application eliminates the use of pre-made sponge film, instead selecting a whole roll of sponge film. The sponge film is cut and supplemented as needed according to product requirements; it is then transferred to the adhesive application area to apply double-sided adhesive; subsequently, it is transferred to the sponge film wrapping area. Once the product is in place, one push roller tightens the sponge film and presses down on the double-sided adhesive. After retracting, the other push roller tightens the other end of the sponge film and presses down on the double-sided adhesive, then retracts. This provides a new approach to the field of sponge film packaging. Attached Figure Description

Detailed Implementation

[0046] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0047] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0048] The columnar fibers described in this invention include columnar fiber products such as glass fiber, carbon fiber, and basalt fiber.

[0049] The slide is generally a linear slide, a common structure in the mechanical field. The linear slide moves back and forth under the action of its driving structure, thereby driving the movement of other components connected to it.

[0050] The foam film is a pre-purchased rectangular sheet of a fixed size, with double-sided adhesive tape attached to both ends of one side. Different products use foam films with varying widths, thicknesses, and lengths, resulting in low versatility.

[0051] Currently, the wrapping of the foam film is done manually. The main tasks at this station are peeling off the double-sided tape, wrapping the foam film, and affixing labels.

[0052] In summary, an automatic sponge film wrapping device for columnar fiber raw material products needs to satisfy the requirements of double-sided adhesive peeling and automatic sponge film wrapping. To streamline the entire process, the existing packaging steps are rearranged. Instead of using pre-finished sponge film, whole rolls of sponge film are selected. The sponge film is cut and supplemented as needed according to product requirements; it is then transferred to the adhesive application position to apply the double-sided adhesive; subsequently, it is transferred to the sponge film wrapping position. Once the product is in place, one push roller tightens the sponge film and presses down on the double-sided adhesive. After retracting, the other push roller tightens the other end of the sponge film and presses down on the double-sided adhesive, then retracts. At this point, the sponge film wrapping is complete, and the product is moved to the next station.

[0053] In this embodiment, the workflow of the automatic winding equipment for columnar fiber raw material sponge film is introduced using a glass fiber direct yarn as an example. As shown in Figure 1, its main working components are a roll sponge film support mechanism 1, a sponge film cutting machine 3, a double-sided adhesive applicator 4, a sponge film feeding mechanism 5, a sponge film smoothing and pressing mechanism 6, a raw material transfer mechanism 7, and an overall equipment frame 9.

[0054] The roll-type sponge film support mechanism 1, the sponge film cutting machine 3, and the overall equipment frame 9 are directly and sequentially fixed to the ground; the double-sided adhesive applicator 4, the sponge film feeding mechanism 5, the sponge film smoothing and pressing mechanism 6, and the raw yarn transfer mechanism 7 are all set at different positions on the overall equipment frame 9.

[0055] As shown in Figure 2, the sponge film support mechanism 1 is fixed to the ground by a support base 11. A cantilever shaft 12 is mounted on the top of the support base 11 via a bearing structure, and the cantilever shaft 12 is rotatable. A paper tube is provided at the center of the rolled sponge film 2. During use, the inner diameter of the paper tube is aligned with the outer diameter of the cantilever shaft 12 and inserted. Multiple expansion blocks 121 are distributed across the cylindrical surface of the cantilever shaft 12. The expansion blocks 121 can tighten the central paper tube of the rolled sponge film. When compressed air is applied, the working surface of the expansion blocks 121 is flush with the surface of the cantilever shaft 12. When compressed air is introduced, the expansion blocks 121 are all lifted and tighten the central paper tube of the sponge film. In this embodiment, a pneumatic expansion shaft structure with expansion blocks is used, such as the structure provided in the published patent "A Pneumatic Expansion Shaft Expansion Block" (Publication No.: CN211366590U). A limiting plate 13 and a limiting ring 14 are respectively provided at the root and outer end of the cantilever shaft 12. A clamp is provided on the side of the limiting plate 13 facing the support base 11 to restrict the position of the limiting plate 13 on that side. The limiting ring 14 is fixed to the end of the cantilever shaft 12 by tightening screws. When the product roll diameter changes, the required width of the sponge film decreases. By loosening the clamp of the limiting plate 13 and the tightening screws of the limiting ring 14, the positions of the limiting plate 13 and the limiting ring 14 on the cantilever shaft 12 can be moved to adapt to rolls of sponge film with different widths. By adjusting the positions of the limiting plate 13 and the limiting ring 14, the center line of the long side of the sponge film is kept in a fixed position when the width and length of the sponge film change. A bearing seat for the cantilever shaft 12 is also provided on the top of the support base 11. To avoid mechanical damage, a safety guard 15 is installed on its outer side.

[0056] As shown in Figure 3, the sponge film cutting machine 3 includes multiple tension rollers 31, a pair of feed rollers 32, a cutter 33, a control box 34, and a bottom support 35. The multiple tension rollers 31, the pair of feed rollers 32, and the cutter 33 are sequentially arranged above the bottom support 35. The rolled sponge film 2 passes through the tension rollers 31 and enters the feed rollers 32, and is then cut into rectangular sponge film 21 by the cutter 33. The controller is installed in the control box 34 to control the movement of the cutter to achieve film cutting. The machine adopts a common film cutting mechanism structure in the mechanical field, and the connection and control relationship of the cutter does not need to be described in detail.

[0057] The main function of the sponge film feeding mechanism 5 is to transfer the cut rectangular sponge film 21. As shown in Figures 3 and 4, the sponge film feeding mechanism 5 is arranged sequentially from the incoming material direction as a transfer panel 51 (located below the rectangular sponge film 21) and a temporary storage panel 53. A sponge film gripper 54 is arranged above the temporary storage panel 53. The transfer position 1 is located at the transfer panel 51, and the transfer position 2 is located at the temporary storage panel 53. Panel slides 511 for controlling the movement of the transfer panel 51 are arranged on both sides below the short side of the transfer panel 51. A pair of rectangular openings 512 are opened in the middle of the transfer panel 51, and a vacuum suction plate 513 is arranged in each of the rectangular openings 512. The surface of the vacuum suction plate 513 is flush with the surface of the transfer panel 51, and a suction plate slide 514 is arranged below the vacuum suction plate 513. Small holes evenly distributed on the panel of the vacuum suction plate 513 are connected to compressed air, so that the rectangular sponge film can be tightly sucked up by the compressed air. The vacuum slide 514 uses a cylinder to move the vacuum suction plate. The vacuum suction plate can move the rectangular sponge film a short distance so that it can be clamped by the sponge film gripper 54 (the sponge film gripper 54 is activated at the transfer position 2).

[0058] The transfer panel 51 has pressure fingers 52 on both sides of its short side for pressing the rectangular sponge film 21. Each pressure finger 52 includes an inner pressure finger and an outer pressure finger. The space between the inner and outer pressure fingers is a central groove, which is the working area for the double-sided adhesive applicator 4, providing working space for its operation. The pressure fingers on both sides are designed to press the rectangular sponge film firmly, preventing movement and wrinkling. The temporary storage panel 53 is used for temporary storage of the rectangular sponge film 21, shortening the work cycle. The sponge film gripper 54 is used for gripping and transferring the rectangular sponge film 21. The base of the sponge film gripper 54 has a vertically movable gripper slide 541, which is mounted on a feeding slide 542. The feeding slide 542 is located on both sides of the temporary storage panel 53 and can move back and forth along the production line direction.

[0059] Double-sided tape needs to be applied to both ends of the rectangular sponge film 21, and this action is completed by the double-sided tape application mechanism 4. As shown in Figures 1 and 5, there are a pair of double-sided tape application mechanisms 4, which are symmetrically arranged around the center line of the long side of the rectangular sponge film and are set above the sponge film feeding mechanism 5. The mechanism includes a tape application sliding seat 41 fixed to the overall frame 9 of the equipment, a tape application cylinder 42 and a mounting plate 43 set on the tape application sliding seat 41, and a hot air blowing device 44 set on the overall frame 9 of the equipment.

[0060] The adhesive-applying sliding seat 41 is mounted on the cantilever extending from the overall frame 9 of the equipment, allowing for forward and backward movement in the feeding direction. Its position is above the short side of the rectangular sponge film 21. A hot air blowing device 44 is also installed on the cantilever extending from the overall frame 9 to ensure normal use of the double-sided adhesive in winter. The adhesive-applying sliding seat 41 is equipped with a vertically moving adhesive-applying cylinder 42, which is connected to a mounting plate 43. The core moving parts of the double-sided adhesive applicator 4 are all mounted on the mounting plate 43. The mounting plate 43 is equipped with a double-sided adhesive traction wheel 431, a tensioning wheel 432, an adhesive applicator roller 433, a guide wheel 434, an adhesive-cutting mechanism 435, and a double-sided adhesive mounting wheel 436. The double-sided adhesive mounting wheel 436 is used to fix the double-sided adhesive. A guide wheel 434 is provided below the double-sided adhesive mounting wheel 436. A glue-cutting mechanism 435 is provided below the guide wheel 434. The glue-cutting mechanism 435 completes the cutting of the double-sided adhesive tape by the cutting and retracting action of the blade without damaging the release paper. A shaft of the adhesive roller 433 is fixed below the glue-cutting mechanism 435. A rotatable adhesive roller 433 is sleeved on the shaft. The adhesive roller 433 is used to press the tape and the sponge film tightly. The double-sided adhesive traction wheel 431 is used to actively pull the double-sided adhesive. The tensioning wheel 432 is used to ensure that the double-sided adhesive is in a taut state.

[0061] The top crossbeam of the overall frame 9 of the equipment is equipped with a raw yarn transfer mechanism 7, as shown in Figure 7. The raw yarn transfer mechanism 7 has two sliding frames 71 slidably mounted above the crossbeam. Each sliding frame 71 has a sliding arm 72 slidably mounted vertically. The bottom of each sliding arm 72 is equipped with a yarn-holding gripper 73. Both the sliding frames 71 and the sliding arms 72 can move under the drive of a driving mechanism, which can be a sprocket chain, gear rack, screw, cylinder, hydraulic cylinder, etc. The yarn-holding gripper 73 can move in both horizontal and vertical directions. The yarn-holding gripper 73 can transfer the raw yarn 8 to three stations. The front yarn-holding gripper can grab the columnar fiber raw yarn from the protective film winding station onto the sponge film smoothing and pressing mechanism, and the rear yarn-holding gripper can grab the wound raw yarn to the discharge station.

[0062] As shown in Figure 6, the sponge film smoothing and pressing mechanism 6 includes a raw yarn storage base 61 and a set of pressing mechanisms located on both sides of the storage base 61. Each pressing mechanism includes a sponge film pressing roller 62, a roller shaft rocker arm 63, a pressing edge roller 64, and a roller shaft rocker arm slide 65. The pressing edge roller 64 includes a roller with its central axis along the feeding direction of the rectangular sponge film 21. The roller is set on the overall frame 9 of the equipment through a lifting structure. The roller shaft rocker arm slide 65 is set on the overall frame 9 of the equipment through a slide structure, forming a crank-rocker mechanism with the roller shaft rocker arm 63 and the rocker arm cylinder 631. The sponge film pressing roller 62 is located at the end of the roller shaft rocker arm 63 and moves its position with the swing of the roller shaft rocker arm 63. The raw yarn storage base 61 is a station for winding the sponge film. First, the sponge film feeding mechanism 5 moves the rectangular sponge film 21 to the raw yarn storage base 61. The raw yarn transfer mechanism 7 also moves the raw yarn 8 to the top of the raw yarn storage base 61 and places it on the rectangular sponge film 21. A base slide 612 is slidably disposed below the raw yarn storage base 61. The pressing roller 64 presses the two ends of the rectangular sponge film 21 that has been moved to the raw yarn storage base 61. After the raw yarn 8 presses down on the rectangular sponge film 21, it is released. Subsequently, the raw yarn storage base 61 sinks under the sliding action of the base slide 612. The roller rocker arm slide 65 on one side moves towards the raw yarn position. The roller rocker arm 63 rotates upward under the action of the rocker arm cylinder 631. The sponge film pressing roller 62 contacts the rectangular sponge film 21 and rolls on the side of the raw yarn 8 under the action of the roller rocker arm 63 until it rolls to the top of the raw yarn 8. At the same time, the double-sided adhesive tape 211 is stuck to the upper side of the raw yarn 8. Then it is reset. Then the other roller rocker arm 63 performs the same action to stick the other side of the double-sided adhesive tape. As shown in Figure 8, the double-sided adhesive tape on the head and tail sides of the sponge film partially overlaps, packaging the raw yarn product inside the sponge film.

[0063] Infrared sensors are respectively installed above the raw filament storage base 61, transfer panel 51, and temporary storage panel 53 of the sponge film smoothing and pressing mechanism 6 to detect whether there is an object above them.

[0064] It also includes a controller, which is connected to the infrared sensors located above the raw yarn storage base, transfer panel, and temporary storage panel. The controller is also connected to the action mechanisms of the roll sponge film support mechanism 1, sponge film cutting machine 3, double-sided adhesive applicator 4, sponge film feeding mechanism 5, sponge film smoothing and pressing mechanism 6, and raw yarn transfer mechanism 7. The controller receives signals from the infrared sensors and controls the action mechanisms.

[0065] For products requiring sponge film wrapping, after the process begins, the raw material storage base 61 of the sponge film smoothing and pressing mechanism 6 will sense whether there is sponge film 21 above it. If no sponge film is detected, a sponge film material request will be issued. The sponge film feeding mechanism 5 moves to the waiting station after the sponge film cutting machine 3. The sponge film will move forward under the rotation of the feeding roller 32 of the sponge film cutting machine 3, and the cantilever shaft 12 of the sponge film support mechanism 1 and the rolled sponge film 2 will rotate under the traction of force. After the sponge film feeding length reaches the set distance of the sponge film cutting machine 3, the feeding roller 32 stops rotating, the cutter 33 moves, and cuts out rectangular sponge film 21. The rectangular sponge film 21 cut by the sponge film cutting machine 3 will fall onto the transfer panel 51. The vacuum suction plate 513 will pick up the rectangular sponge film 21 and move a small distance towards the sponge film wrapping station under the drive of the suction plate slide 514. Once in position, the pressure finger 52 moves downward to press the rectangular sponge film 21, and the vacuum suction plate 513 stops sucking air and resets. The main actuator of the double-sided adhesive applicator 4 moves towards the rectangular sponge film 21 under the drive of the adhesive applicator slide seat 41. During this process, the hot air blower 44 preheats the tape according to its activation status. After the adhesive applicator slide seat 41 is in position, the adhesive applicator cylinder 42 is activated, and the mounting plate 43 moves downward until the adhesive applicator roller 433 presses against the rectangular sponge film 21. Subsequently, the adhesive applicator slide seat 41 moves in the opposite direction, and the double-sided adhesive traction wheel 431 rotates simultaneously. The double-sided adhesive will detach from the release paper under the action of the adhesion between the double-sided adhesive and the sponge film and the pressing of the adhesive applicator roller 433. After traveling half the distance, the blade of the adhesive cutting mechanism 435 is activated to cut the tape without damaging the release paper. The adhesive applicator slide seat 41 and the double-sided adhesive traction wheel 431 continue to operate until the double-sided adhesive tape 211 is completely adhered to the surface of the rectangular sponge film 21, and the adhesive applicator cylinder 42 and the adhesive applicator slide seat 41 reset. Subsequently, the transfer panel 51 moves towards the sponge film winding station under the drive of the panel slide 511 until it approaches the temporary storage panel 53. Then, the sponge film gripper 54 of the feeding mechanism 5 opens and moves towards the sponge film. After it is in place, it closes and clamps the long side of the rectangular sponge film 21 and moves in the opposite direction to transfer the rectangular sponge film 21 above the raw yarn storage base 61. At the same time, the sponge film pressure roller 62 presses down on the two short sides of the rectangular sponge film 21. While the sponge film gripper 54 of the feeding mechanism 5 is transferring the material, since there is no material at the temporary storage panel 53 and the transfer panel 51 is in a waiting state, it will also send a material request to the sponge film cutting machine 3. Until the sponge film gripper 54 of the feeding mechanism 5 transfers the new rectangular sponge film 21 to the temporary storage panel 53, if both the raw yarn storage base 61 and the temporary storage panel 53 detect the rectangular sponge film 21, the transfer panel 51 will also send a request to the sponge film cutting machine 3. That is, the cutting of the sponge film will only stop after the three conditions of the raw yarn storage base 61, the temporary storage panel 53 and the transfer panel 51 are met.When the raw yarn storage base 61 detects the sponge film, the raw yarn transfer mechanism 7, under the action of the sliding frame 71 moving laterally, the sliding arm 72 moving longitudinally, and the yarn clamping claw 73 grasping action, grabs the columnar fiber raw yarn from the protective film winding station to the raw yarn storage base 61 of the sponge film smoothing and pressing mechanism 6. Then the sponge film pressure roller 62 is released, and the raw yarn storage base 61 sinks under the action of the base slide 612. The rocker arm slide 65 on one side moves towards the raw yarn position, and the roller rocker arm 63 rotates upward under the action of the rocker arm cylinder 631 extending. The sponge film pressure roller 62 contacts the sponge film 21 and rolls on the side of the raw yarn 8 under the action of the roller rocker arm 63 until it rolls to the top of the raw yarn 8. At the same time, the tape 211 is stuck to the upper side of the raw yarn 8, and then it is reset. Then the other side is pressed with the same action to stick the other double-sided tape firmly. After completion, the raw yarn transfer mechanism 7, through the lateral movement of the sliding frame 71, the longitudinal movement of the sliding arm 72, and the gripping action of the yarn clamping claw 73, picks up the wound raw yarn and moves it to the discharge station. The sponge film winding action is completed.

[0066] Furthermore, as shown in Figure 4, the transfer panel 51 is provided with bending limiters 515 on both sides to prevent misalignment of the sponge film.

[0067] Furthermore, the raw filament storage base 61 has a structure that is low in the middle and high on both sides, and nylon material pads 611 are provided on the two inclined surfaces to facilitate the storage of raw filaments.
