[0002] As people's demands for quality of life become higher and higher, strong and lightweight materials are gradually replacing metal materials in people's lives. Reinforcing fibers such as glass fiber, as important basic materials for industrial strengthening, are widely used in construction materials, clean energy, aerospace and other fields.

[0003] Although fiber-based reinforcement materials can be used as a reinforcement base and mixed with resin to form excellent plastic materials, which make the plastic have higher impact toughness, insulation performance, bending tensile strength and creep resistance, the fiber itself is hard and brittle, and it is easy to break and fluff after being bumped, especially during transfer and transportation, which affects the subsequent product process.

[0004] Therefore, columnar fiber raw silk products are formed through wire drawing and curling 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 hands of customers.

[0005] At present, in order to ensure that the product does not bump during transportation, the outer ring of columnar fiber raw yarn is usually wrapped with a protective film and then wrapped with a 3-5mm thick sponge film. The sponge film is a purchased finished product. When used, the double-sided tape at both ends is manually peeled off and wrapped around the outside of the product, and the double-sided tape is pressed to ensure that the package is tight. The packaging process is labor-intensive and the packaging efficiency is low. Summary of the invention

[0019] Furthermore, the raw silk storage base is a structure with a low middle and high sides, and pads made of nylon material are arranged on the two inclined surfaces to facilitate the storage of the raw silk.

[0020] Infrared sensors are respectively arranged above the raw silk storage base, the transfer panel and the 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 provided with a raw silk transfer mechanism, and the raw silk transfer mechanism is provided with a sliding frame slidingly above the crossbeam. There are two sliding frames, and each sliding frame is provided with a sliding arm sliding in the vertical direction. The bottom of the sliding arm is provided with a yarn clamping claw. The sliding frame and the sliding arm can be moved under the drive of the driving mechanism, and the yarn clamping claw can realize the horizontal and vertical movement. The yarn clamping claw can realize the transfer of raw silk in three stations. The front yarn clamping claw can grab the columnar fiber raw silk from the protective film winding station to the sponge film smoothing and pressing mechanism, and the rear yarn clamping claw can grab the raw silk after winding to the discharge station.

[0022] Preferably, it also includes a sponge film support mechanism, which is fixed to the ground by a support base, and a cantilever shaft is installed on the top of the support base through a bearing structure, and the cantilever shaft is rotatable; the cantilever shaft is an air-expanding shaft structure to achieve the winding and unwinding of the entire roll of sponge film.

A bearing seat of the cantilever shaft is also provided on the top of the support base, and a safety shield is installed on its outer side to avoid mechanical damage.

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

[0024] Step 1: The infrared sensor of the raw silk storage base of the sponge film smoothing and pressing mechanism senses whether there is a sponge film on it; if it cannot be sensed, a sponge film material request will be issued;

[0025] Step 2, the sponge film feeding mechanism goes to the material waiting station behind the sponge film cutting machine, and the sponge film cutting machine supplies the cut rectangular sponge film;

[0026] The sponge film will move 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 rolled sponge film will rotate under the traction of the force; after the sponge film discharge length reaches the set distance of the sponge film cutting machine, the feed roller stops rotating, the cutter moves, and a rectangular sponge film is cut out;

[0027] The rectangular sponge film will fall onto the transfer panel, and the vacuum suction plate will suck the rectangular sponge film. Driven by the suction plate slide, it will move a certain distance toward the sponge film winding station. 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 adhesive gluing mechanism moves toward the rectangular sponge film driven by the gluing sliding seat. During this period, the hot air blowing device will preheat the tape according to the opening status. After the gluing sliding seat is in place, the gluing cylinder is activated and the mounting plate moves downward until the gluing roller presses the rectangular sponge film. Then, the gluing sliding seat moves in the opposite direction, and the double-sided adhesive traction wheel rotates at the same time. The double-sided adhesive will be separated from the release paper under the viscosity of the sponge film and the pressure of the gluing roller. After traveling half the distance, the blade of the glue cutting mechanism is activated to cut the tape without The release paper is damaged, and the gluing sliding seat and the double-sided adhesive traction wheel continue to move until the double-sided adhesive tape is completely adhered to the surface of the rectangular sponge film, and the gluing cylinder and the gluing sliding seat are reset; then, the transfer panel is driven by the panel sliding seat to move toward the sponge film winding station until it approaches the temporary storage panel, and then the sponge film clamping claw of the feeding mechanism opens and moves to the sponge film, and after it is in place, it closes and clamps the long side of the rectangular sponge film, and moves in the opposite direction to transfer the rectangular sponge film to the top of the original silk storage base, and at the same time, the sponge film pressing roller presses the two short sides of the rectangular sponge film;

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

[0030] If the original silk 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 be stopped only after the three conditions of the original silk storage base, the temporary storage panel and the transfer panel are met;

[0031] Step 4, when the raw silk storage base detects the sponge film, the raw silk transfer mechanism grabs the columnar fiber raw silk from the protective film winding station to the raw silk storage base of the sponge film flattening and pressing mechanism under the lateral movement of the sliding frame, the longitudinal movement of the sliding arm and the clamping action of the yarn holding claw, and then the sponge film pressure roller is released, and the raw silk storage base sinks under the action of the base slide, and the rocker slide on one side moves toward the raw silk position, and the roller rocker rotates upward under the action of the rocker cylinder extending, and the sponge film pressure roller contacts the sponge film and rolls on the side of the raw silk under the action of the roller rocker until it rolls to the top of the raw silk, and at the same time sticks the tape to the upper side of the raw silk, and then resets, and then the other side is glued with the other side of the double-sided tape in the same way;

[0032] After the winding is finished, the original yarn transfer mechanism grabs the original yarn after winding to the discharge station under the action of the horizontal movement of the sliding frame, the longitudinal movement of the sliding arm and the clamping action of the yarn holding claw. The sponge film winding action is completed.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present application provides an automatic sponge film winding device for columnar fiber precursor products, which can realize automatic feeding, gluing, feeding, winding, wrapping, pressing and other actions of the sponge film, which is conducive to reducing work intensity, while lowering the purchase cost of the sponge film and increasing corporate profits.

[0035] 2. Traditional sponge film needs to be peeled off the double-sided tape and wrapped with the sponge film; different from this, this application no longer uses finished sponge film, but selects a whole roll of sponge film, cuts and fills the sponge film as needed according to product requirements; transfers to the gluing position to paste the double-sided tape; then transfers to the sponge film wrapping position, after the product is in place, the push roller on one side will tighten the sponge film and press the double-sided tape position, and after the product is returned, the push roller on the other side will tighten the sponge film on the other end and press the double-sided tape position, and then return after the product is returned. It provides a new idea for the sponge film packaging field. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0054] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0055] The columnar fibers described in the present invention include columnar fiber products such as glass fibers, carbon fibers, and basalt fibers.

[0056] The slide is generally a linear slide, which is a commonly used structure in the mechanical field. The linear slide moves back and forth under the action of its driving structure, thereby driving other components connected to it to move.

[0057] The sponge film is a purchased finished product, a rectangular film of fixed size, with double-sided tape attached to both ends of one side. The sponge film used in different products has different widths, thicknesses, and lengths, and has low versatility.

[0058] Currently, the sponge film wrapping is done manually. The work of this station mainly involves double-sided tape peeling, sponge film wrapping and label pasting.

[0059] In summary, an automatic sponge film winding equipment for columnar fiber precursor products must meet the requirements of stripping the double-sided adhesive tape of the sponge film and automatically wrapping and winding the sponge film. In order to facilitate the entire process, the existing packaging process is rearranged, and the finished sponge film is no longer used. Instead, a whole roll of sponge film is selected. According to the product requirements, the sponge film is cut and supplemented as needed; it is transferred to the gluing position to paste the double-sided adhesive tape; then it is transferred to the sponge film wrapping position. After the product is in place, a push roller on one side will tighten the sponge film and press the double-sided adhesive tape position. After it is completed and returned, the push roller on the other side will tighten the sponge film at the other end and press the double-sided adhesive tape position. After it is completed, it will return. At this point, the sponge film wrapping and winding is completed, and the product moves to the next station.

[0060] In this embodiment, a glass fiber direct yarn is used as an example to introduce the working process of the automatic winding device for the sponge film of the columnar fiber raw silk product. Figure 1 As shown, its main working parts are a roll sponge film supporting mechanism 1, a sponge film cutting machine 3, a double-sided adhesive gluing mechanism 4, a sponge film feeding mechanism 5, a sponge film smoothing and pressing mechanism 6, a raw silk transferring mechanism 7, and an overall equipment frame 9.

[0061] The rolled sponge film supporting mechanism 1, the sponge film cutting machine 3, and the overall frame of the equipment 9 are directly fixed on the ground in sequence; the double-sided adhesive gluing mechanism 4, the sponge film feeding mechanism 5, the sponge film smoothing and pressing mechanism 6, and the raw silk transferring mechanism 7 are all arranged at different positions of the overall frame of the equipment 9.

[0062] like Figure 2 As shown, the sponge membrane support mechanism 1 is fixed to the ground by a support base 11, and a cantilever shaft 12 is installed on the top of the support base 11 through a bearing structure, and the cantilever shaft 12 is rotatable. A paper tube is provided in the center of the rolled sponge membrane 2. When in use, the inner diameter of the paper tube is aligned with the outer diameter of the cantilever shaft 12 and inserted. A plurality of expansion blocks 121 are distributed on the cylindrical surface of the cantilever shaft 12. The expansion block 121 can tighten the central paper tube of the rolled sponge membrane. The expansion block 121 is operated by compressed air. When compressed air is not introduced, the working surface of the expansion block 121 is flush with the surface of the cantilever shaft 12. When compressed air is introduced, the expansion blocks 121 are all lifted up and tighten the central paper tube of the sponge membrane. In this embodiment, an air expansion shaft structure with an expansion block is used, such as the structure provided by the patent publication "A kind of air expansion shaft expansion block" (publication number: CN211366590U). The root and outer end of the cantilever shaft 12 are respectively provided with a limit plate 13 and a limit ring 14. The limit plate 13 is provided with a clamp on the side facing the support base 11 to limit the position of the limit plate 13 on that side; the limit ring 14 is fixed to the end of the cantilever shaft 12 by a loosening screw. When the roll diameter of the product changes, the required width of the sponge film is reduced. By loosening the clamp of the limit plate 13 and the loosening screw of the limit ring 14, the position of the limit plate 13 and the limit ring 14 on the cantilever shaft 12 can be moved to adapt to the rolled sponge film of different widths. The position of the limit plate 13 and the limit ring 14 is adjusted to ensure that when the width and length of the sponge film change, the center line of its long side remains in a fixed position. The top of the support base 11 is also provided with a bearing seat of the cantilever shaft 12. In order to avoid mechanical damage, a safety shield 15 is installed on its outer side.

A guide wheel 434 is arranged below the double-sided adhesive tape installation wheel 436. A glue-cutting mechanism 435 is arranged below the guide wheel 434. The glue-cutting mechanism 435 completes the cutting of the double-sided adhesive tape by the cutting-in and withdrawing actions of the blade without damaging the release paper. The shaft of the glue-applying roller 433 is fixed below the glue-applying mechanism 435. A rotatable glue-applying roller 433 is sleeved on the shaft. The glue-applying roller 433 is used to press the adhesive tape and the sponge film. The double-sided adhesive tape traction wheel 431 is used to actively pull the double-sided adhesive tape. The tensioning wheel 432 is used to ensure that the double-sided adhesive tape is in a tensioned state.

[0071] It also includes a controller, which is respectively connected to the infrared sensors arranged on the raw silk storage base, the transfer panel, and the temporary storage panel, and is respectively connected to the action mechanisms of the roll sponge film support mechanism 1, the sponge film cutting machine 3, the double-sided adhesive gluing mechanism 4, the sponge film feeding mechanism 5, the sponge film smoothing and pressing mechanism 6, and the raw silk transfer mechanism 7 by signal, receives the signal of the infrared sensor, and controls the action of the action mechanism.

[0072] For products that need to be wrapped with sponge film, after the process starts, the raw silk storage base 61 of the sponge film smoothing and pressing mechanism 6 will sense whether there is a sponge film 21 above it. If it cannot be sensed, a request for sponge film material will be issued. The sponge film feeding mechanism 5 goes to the material waiting station behind the sponge film cutting machine 3. The sponge film will move forward under the rotation of the feed 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 the force. After the sponge film discharge length reaches the set distance of the sponge film cutting machine 3, the feed roller 32 stops rotating, and the cutter 33 moves to cut out a rectangular sponge film 21. The rectangular sponge film 21 cut by the sponge film cutting machine 3 will fall onto the transfer panel 51, and the vacuum suction plate 513 sucks the rectangular sponge film 21, and moves a small distance toward the sponge film winding station driven by the suction plate slide 514. After being in place, the pressing 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 gluing mechanism 4 moves toward the rectangular sponge film 21 driven by the gluing sliding seat 41. During this period, the hot air blowing device 44 will preheat the tape according to the opening situation. After the gluing sliding seat 41 is in place, the gluing cylinder 42 is activated, and the mounting plate 43 moves downward until the gluing roller 433 presses the rectangular sponge film 21. Then, the gluing sliding seat 41 moves in the opposite direction, and the double-sided adhesive traction wheel 431 rotates at the same time. The double-sided adhesive will be separated from the release paper under the viscosity of the sponge film and the pressure of the gluing roller 433. After traveling half the distance, the blade of the glue cutting mechanism 435 is activated to cut the tape without damaging the release paper. The gluing sliding seat 41 and the double-sided adhesive traction wheel 431 continue to move until the double-sided adhesive tape 211 is completely adhered to the surface of the rectangular sponge film 21, and the gluing cylinder 42 and the gluing sliding seat 41 are reset. Subsequently, the transfer panel 51 is driven by the panel slide 511 to move toward the sponge film winding station until it approaches the temporary storage panel 53. Then, the sponge film clamping claws 54 of the feeding mechanism 5 open and move toward the sponge film. After reaching the position, they close and clamp the long sides of the rectangular sponge film 21, and move in the opposite direction to transfer the rectangular sponge film 21 to the top of the raw silk storage base 61. At the same time, the sponge film pressing rollers 62 press the two short sides of the rectangular sponge film 21. While the sponge film clamp 54 of the feeding mechanism 5 is transferring, since there is no material at the temporary storage panel 53 and the transfer panel 51 is in a material waiting state, a material request will also be issued to the sponge film cutting machine 3 until the sponge film clamp 54 of the feeding mechanism 5 transfers the new rectangular sponge film 21 to the temporary storage panel 53. If the raw silk storage base 61 and the temporary storage panel 53 both detect the rectangular sponge film 21, the transfer panel 51 will also issue a request to the sponge film cutting machine 3. That is, the cutting of the sponge film will be stopped only after the three conditions of the raw silk storage base 61, the temporary storage panel 53 and the transfer panel 51 are met.When the raw silk storage base 61 detects the sponge film, the raw silk transfer mechanism 7 grabs the columnar fiber raw silk from the protective film winding station to the raw silk storage base 61 of the sponge film smoothing and pressing mechanism 6 under the lateral movement of the sliding frame 71, the longitudinal movement of the sliding arm 72 and the clamping action of the yarn holding claw 73. Then the sponge film pressure roller 62 is released, and the raw silk storage base 61 sinks under the action of the base slide 612, and the rocker slide 65 on one side moves toward the raw silk position, and the roller rocker arm 63 rotates upward under the extension of the rocker arm cylinder 631. The sponge film pressure roller 62 contacts the sponge film 21 and rolls on the side of the raw silk 8 under the action of the roller rocker arm 63 until it rolls to the top of the raw silk 8, and at the same time sticks the tape 211 to the upper side of the raw silk 8, and then resets, and then the other side is glued with the other side of the double-sided tape in the same way. After the winding is finished, the original yarn transfer mechanism 7 grabs the original yarn after winding to the discharge station under the lateral movement of the sliding frame 71, the longitudinal movement of the sliding arm 72 and the clamping action of the yarn holding claw 73. The sponge film winding action is finished.

[0073] Further, such as Figure 4 As shown, bending limiters 515 are provided on both sides of the transfer panel 51 to prevent the sponge membrane from being misplaced.

[0074] Furthermore, the raw silk storage base 61 is a structure with a low middle and high sides, and pads 611 made of nylon are arranged on two inclined surfaces to facilitate the storage of raw silk.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
