Description

Technical Field

[0001] This invention relates to the field of fiber winding technology, specifically to a flame-retardant protein fiber winding device. Background Technology

[0002] New energy vehicle battery packs face safety challenges during operation, including physical impact, thermal runaway, and environmental corrosion. To provide physical protection, prevent the spread of thermal runaway, and resist environmental corrosion, the outer wall of the battery pack is often wrapped with a fire-resistant cover made of a blend of para-aramid, meta-aramid, and flame-retardant cotton. During production, these three fibers need to be converted into tubular rolls using a special fiber winding machine for convenient subsequent processing. A special fiber winding machine is a device that winds special fibers (such as aramid, carbon fiber, ultra-high molecular weight polyethylene fiber, and flame-retardant protein fiber). Its core function is to wind special fibers into tubular shapes that meet the requirements of subsequent processing (such as weaving, compounding, and molding) through precise mechanical and electronic control, ensuring that the physical properties of the fibers (such as strength, toughness, and flame retardancy) are not damaged.

[0003] For example, the patent publication number CN204038779U discloses an automatic continuous winding and take-up device for carbon fiber, which includes a base, a guide mechanism disposed on the base, a take-up changing seat with a spool seat, a winding change driving mechanism that drives the take-up changing seat to change the spool seat so that it alternately corresponds to the guide mechanism, and a winding and take-up driving mechanism that drives the spool seat to rotate; at least two spool seats and a wire cutting mechanism corresponding to each spool seat are fixedly connected to the take-up changing seat; the guide mechanism, the winding change driving mechanism and the winding and take-up driving mechanism are all signal connected to an automatic control system.

[0004] While the aforementioned device solves the problems of yarn take-up and roll changing, it still has the following drawbacks: After the fiber roll is fully wound, the system uses an automatic replacement mechanism to rotate the roll to be wound into the working position. Subsequently, the yarn cutter cuts the fiber bundle on the roll, but the cut end lacks fixation with the roll after cutting. After the roll stops, the remaining kinetic energy causes the fiber to continue moving due to inertia, which leads to the cut end loosening, resulting in the wound bundle becoming loose and causing inconvenience. Summary of the Invention

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figure 1 - Figure 10A flame-retardant protein fiber winding device includes a winding machine body 1, a control panel 2 connected to the winding machine body 1, and two winding rollers 3 connected to the winding machine body 1. A base plate 4 is connected to the outer wall of the winding machine body 1. An L-shaped mounting plate 20 is slidably connected to the top surface of the base plate 4. An insertion sleeve 39 is fixedly connected to the inner wall of the vertical plate in the L-shaped mounting plate 20. An adhesive tape 16 is rotatably attached to the outer side of the insertion sleeve 39. Two sets of limiting rollers 18 are rotatably connected to the inner wall of the vertical plate in the L-shaped mounting plate 20. A positioning roller 23 is provided. One end of the adhesive tape 16 passes through two sets of limiting rollers 18 and is located outside the positioning roller 23. The adhesive tape 16 has an adhesive side that is close to the outside of the winding roller 3. A back plate 6 is fixedly connected to the side of the L-shaped mounting plate 20 away from the winding roller 3. A pushing structure is connected to the outer wall of the back plate 6. A cutting structure is connected to the top surface of the back plate 6. An air suction structure is connected to the outside of the positioning roller 23. A rotating structure is connected to the outside of the L-shaped mounting plate 20. A squeezing structure is connected to the top of the L-shaped mounting plate 20.

[0031] In the flame-retardant protein fiber winding device of this invention, when the fiber bundle on the outer side of one of the winding rollers 3 in the winding machine body 1 is fully wound, it will rotate itself, adjusting the other empty winding roller 3 to the waiting position, while the fully wound winding roller 3 rotates to the exit position. When the fully wound winding roller 3 reaches the exit position, the wire needs to be cut. Before the wire is cut, the wire bundle will move closer to the wire cutting knife (existing technology). At this time, the pushing structure pushes the L-shaped mounting plate 20 to move closer to the side of the fully wound winding roller 3, so that the extrusion structure is pressed tightly against the wire bundle and the roll material. Then, as the L-shaped mounting plate 20 continues to move, the adhesive tape 1... 6. Adhesive tape 16 is continuously released as the roll rotates, and then the rotating structure is activated, causing the structure inside the L-shaped mounting plate 20 to rotate and tilt. Then the cutting structure cuts the adhesive tape 16. In this way, the wire harness is adhered to the outside of the roll by the adhesive tape 16, and after the wire harness is cut by the wire cutter (existing technology), only one end remains loose outside, which does not affect the overall looseness of the roll. After that, the pushing structure drives the L-shaped mounting plate 20 to move backward and reset, ensuring that the next full roll can rotate smoothly to make way for it, and repeating the above operation to complete the adhesion and fixation between the wire harness head and the roll of each roll.

[0032] When installing the adhesive tape 16, the beginning of the adhesive tape 16 can be torn open and passed through the space between the two sets of limiting rollers 18, with the opening of the adhesive tape 16 positioned between the positioning roller 23 and the roll material. When the adhesive tape 16 is released by the roll material, the adhesive tape 16 will be released between the two sets of limiting rollers 18. Both the limiting rollers 18 and the positioning rollers 23 are rotatable, which can ensure that the adhesive tape 16 can be smoothly rotated and released.

[0033] By installing an L-shaped mounting plate 20, adhesive tape 16, a limiting roller 18, and a positioning roller 23 on one side of the roll material, the wire harness head can be reliably adhered and fixed to the outside of the roll material. As the roll material rotates, the adhesive tape 16 is released and precisely cut by a cutting mechanism, facilitating the adhesion and fixation of the next roll material. This structural design effectively ensures that the wire harness head remains firmly attached to the roll material surface after unloading, preventing the wound roll material from becoming loose and improving the overall stability and reliability of the winding process.

[0034] As a preferred embodiment of the present invention, the cutting structure includes a mounting box 28 and a cutting blade 32. The mounting box 28 is fixedly mounted on the top surface of the back plate 6. A reciprocating screw 33 is rotatably connected inside the mounting box 28. A moving block 31 is threadedly connected to the outer side of the reciprocating screw 33. A strip groove 30 is provided on the outer wall of the mounting box 28. After the moving block 31 passes through the strip groove 30, one end is fixedly connected to the cutting blade 32 for cutting the adhesive tape 16. A reciprocating motor 29 is fixedly mounted on one end of the outer wall of the mounting box 28. The output end of the reciprocating motor 29 is connected to the reciprocating screw 33.

[0035] Specifically, after the adhesive tape 16 is released to a certain extent, the reciprocating motor 29 starts and drives the reciprocating screw 33 to rotate. Under the limit of the strip groove 30, the moving block 31 drives the cutting blade 32 to move back and forth, so that the cutting blade 32 cuts the adhesive tape 16. The adhesive tape 16 can be cut by using the cutting blade 32.

[0036] As a preferred embodiment of the present invention, the air intake structure includes an air pipe 24, an air intake groove 40 is provided on the axis of the positioning roller 23, a plurality of air intake holes 37 are provided on the inner wall of the air intake groove 40, a connector 38 is fixedly connected to the outer end of the positioning roller 23, a rotary head 36 is rotatably connected to the outer side of the connector 38, the air pipe 24 is fixedly installed on the outer wall of the rotary head 36, a negative pressure device is connected to the air pipe 24, and a sponge sleeve 17 is fixedly sleeved on the outer wall of the positioning roller 23, the sponge sleeve 17 is attached to the outer wall of the adhesive tape 16.

[0037] Specifically, in order to ensure that the adhesive tape 16 is always attached to the outside of the positioning roller 23, the air pipe 24 draws air from the air intake groove 40 through the negative pressure device, so that the positioning roller 23 is negatively pressured. Through multiple air intake holes 37, the sponge sleeve 17 can always adsorb the side of the adhesive tape 16 without adhesive. As the adhesive tape 16 is released, the release force of the adhesive tape 16 can overcome the adsorption force, ensuring the smooth release of the adhesive tape 16.

[0038] To ensure that the sponge sleeve 17 can adhere to the back of the adhesive tape 16 for auxiliary positioning, and to ensure that the adhesive tape 16 can be smoothly pulled and released by the roll material, the negative pressure value ranges from -3kPa to -15kPa (gauge pressure). The adhesive tape 16 is usually made of lightweight material (thickness 0.05-0.2mm, weight <50g / m). Combined with the contact area of ​​the sponge sleeve 17 (the diameter of the positioning roller 23 is generally 30-50mm, the length is 50-100mm, and the contact area is about 0.005-0.015㎡), according to the formula F = P × SF = P × S (adhesive force = negative pressure × area), -3kPa can generate an adhesive force of about 15-45N, which is sufficient to fix the adhesive tape.

[0039] The adhesive tape 16 needs to be released by the pulling force (approximately 5-20N) when the roll material rotates, which overcomes the adsorption force. Therefore, the negative pressure needs to be lower than the adhesive force between the adhesive tape 16 and the roll material (usually >20N). The maximum adsorption force corresponding to -15kPa is approximately 75-225N. If this range is exceeded, the adhesive tape may fail to release or be stretched and deformed.

[0040] Based on the above, -5kPa to -10kPa is preferred. The negative pressure is dynamically adjusted according to the thickness of the adhesive tape (the thicker the tape, the higher the negative pressure is required) and the roll speed (the faster the speed, the lower the negative pressure is required).

[0041] The foam sleeve 17 is made of high-density polyurethane foam (density 30-50kg / m³), with a hardness of Shore 20-30A. It combines elasticity (to fit the surface of the adhesive tape) and abrasion resistance (to extend service life). It has a thickness of 5-10mm and a pore size of 30-80μm.

[0042] The suction hole 37 has a diameter of 1-2mm, and one hole is opened every 10-15mm along the axial direction of the positioning roller, with 3-4 rows evenly distributed in the circumferential direction (a total of 12-20 holes, for positioning rollers 23 with a length of 50-100mm); the suction groove 40 has a diameter of 8-12mm.

[0043] The parameters mentioned above are for application reference only; the actual usage shall prevail.

[0044] When the positioning roller 23 rotates under friction, it will rotate on the vertical side wall of the L-shaped mounting plate 20. The positioning roller 23 will also drive the joint 38 to rotate. The rotary head 36 on the outside of the joint 38 can ensure that the negative pressure passes smoothly and also ensure the rotation of the positioning roller 23.

[0045] The gas supply equipment uses existing and mature technologies, such as negative pressure pumps, which are common knowledge in this field, so they will not be described in detail.

[0046] As a preferred embodiment of the present invention, the pushing structure includes an L-shaped vertical plate 7 and a first electric push rod 5. The first electric push rod 5 is fixedly installed on the top surface of the base plate 4. The output end of the first electric push rod 5 is fixedly installed on the outer wall of the vertical plate in the L-shaped vertical plate 7. A connecting plate 19 is fixedly connected to the outer end of the horizontal plate of the L-shaped vertical plate 7. A side plate 12 is fixedly connected to the top surface of one side of the connecting plate 19. The side plate 12 is connected to the L-shaped mounting plate 20.

[0047] Specifically, in order to ensure that the full roll and the empty roll can be replaced smoothly, the L-shaped mounting plate 20 needs to have a clearance function. Therefore, the first electric push rod 5 is started, and its output end can drive the L-shaped vertical plate 7 to move back and forth, thereby driving the connecting plate 19, the side plate 12 and the L-shaped mounting plate 20 and other structures to move back and forth, so as to ensure the replacement of the two winding rollers 3.

[0048] As a preferred technical solution of the present invention, a guide groove 10 is provided on the base plate 4, and a slider 11 is slidably connected in the guide groove 10. The slider 11 is fixedly connected to the bottom surface of the horizontal plate of the L-shaped vertical plate 7.

[0049] Specifically, when the L-shaped upright plate 7 moves back and forth, the L-shaped upright plate 7 will move on the base plate 4, and the L-shaped upright plate 7 will drive the slider 11 to move within the guide groove 10. This setting ensures the guiding nature of the movement of the L-shaped upright plate 7.

[0050] As a preferred technical solution of the present invention, the rotating structure includes a rotating shaft 34, which is fixedly connected to the outer wall of the vertical plate of the L-shaped mounting plate 20. The outer end of the rotating shaft 34 passes through the side plate 12 and is rotatably connected to the side plate 12. The outer wall of the back plate 6 is rotatably connected to a second electric push rod 8, and the other end of the second electric push rod 8 is rotatably connected to the inner wall of the vertical plate of the L-shaped upright plate 7.

[0051] Specifically, to ensure that the adhesive tape 16 does not damage the roll material during cutting, the second electric actuator 8 is activated before cutting, pulling the back plate 6 back. The back plate 6, along with the L-shaped mounting plate 20, rotates along the axis of the rotating shaft 34. Figure 5 As shown, the rotating shaft 34 rotates on the side plate 12, and the second electric push rod 8 can be pushed out and retracted at a controllable distance, effectively ensuring that the adhesive tape 16 in the L-shaped mounting plate 20 is reset and tilted. When the L-shaped mounting plate 20 is tilted, the positioning roller 23 will squeeze the roll material and tilt it, causing the adhesive tape 16 to tilt away from the roll material. Then the cutting blade 32 moves back and forth to cut the adhesive tape 16. By tilting the adhesive tape 16 before cutting it, the adhesive tape 16 is separated from the roll material by a certain distance during cutting, which can prevent the roll material from being scratched or cut during cutting.

[0052] In a preferred embodiment of the present invention, a baffle 25 is fixedly connected to the connecting plate 19 and the side plate 12 on the side away from the back plate 6, and the inner wall of the baffle 25 abuts against the outer wall of one end of the L-shaped mounting plate 20. When the L-shaped mounting plate 20 is reset, the baffle 25 serves to block the L-shaped mounting plate 20.

[0053] As a preferred embodiment of the present invention, the extrusion structure includes an extrusion roller 14, an L-shaped top plate 13 fixedly connected to the top surface of the side plate 12, a U-shaped frame 15 connected to the inner wall of the horizontal plate of the L-shaped top plate 13, the two ends of the extrusion roller 14 being rotatably connected within the U-shaped frame 15, two sliding columns 27 fixedly connected to the outer wall of the U-shaped frame 15, the sliding columns 27 passing through the horizontal plate of the L-shaped top plate 13 and being slidably connected thereto, a spring 35 sleeved on the outer side of the sliding column 27, one end of the spring 35 being fixedly connected to the outer wall of the U-shaped frame 15, and the other end being fixedly connected to the inner wall of the horizontal plate of the L-shaped top plate 13, and a second diagonal brace 26 fixedly connected between the horizontal plate and the vertical plate of the L-shaped top plate 13.

[0054] Specifically, when the first electric push rod 5 moves the connecting plate 19 and the side plate 12 close to the roll material, the extrusion roller 14 first contacts the roll material, extruding the wire harness into the roll material to facilitate subsequent bonding. After the extrusion roller 14 contacts the roll material, the first electric push rod 5 continues to move forward, causing the adhesive tape 16 to adhere to the roll material. Meanwhile, the extrusion roller 14 moves the U-shaped frame 15 and the sliding column 27 outside the L-shaped top plate 13, while simultaneously extruding the spring 35. Subsequently, the second electric push rod 8 is activated, rotating the L-shaped mounting plate 20, causing the positioning roller 23 to rotate around the axis of the rotating shaft 34, causing the adhesive tape 16 to tilt. At this time, the reciprocating motor 29 is activated, causing the cutting blade 32 to reciprocate and cut the adhesive tape 16. Then, as the second electric push rod 8 resets, the first electric push rod 5 also resets, the positioning roller 23 and the extrusion roller 14 leave the roll material, and the sliding column 27 slides under the action of the spring 35, pushing the U-shaped frame 15 and the extrusion roller 14 back to their original positions, waiting for the next bonding with the roll material.

[0055] The second diagonal brace 26 is provided to enhance the strength between the horizontal and vertical plates of the L-shaped top plate 13.

[0056] As a preferred embodiment of the present invention, the outer end of the plug sleeve 39 is threaded with a compression ring 22 for preventing the adhesive tape 16 from falling off.

[0057] Specifically, when one roll of adhesive tape 16 is used up, the compression ring 22 can be detached from the plug sleeve 39, the adhesive tape 16 can be replaced, and finally the compression ring 22 can be used to fix the adhesive tape 16 in the plug sleeve 39.

[0058] As a preferred technical solution of the present invention, the outer wall of the base plate 4 is fixedly connected to two first diagonal braces 21, and the outer ends of the two first diagonal braces 21 are fixedly connected to a fixing plate 9. The fixing plate 9 is threadedly connected to the outer wall of the winding machine body 1 by fastening bolts.

[0059] Specifically, the base plate 4 can be easily fixed to the outer wall of the winding machine body 1 by means of two first diagonal braces 21 and fixing plate 9. The base plate 4 can also be supported by contacting the ground through vertical support rods.

[0060] The first electric actuator 5, the second electric actuator 8, and the reciprocating motor 29 are all existing common technologies;

[0061] The first electric actuator 5 can be model DYTZ450-300 / 110, with a thrust of 4500N (450×10N), a stroke of 300mm, a speed of 110mm / s, and a motor power of 0.75KW (Y802-4).

[0062] The second electric actuator 8 can be model DYTZ700-200 / 110, with a thrust of 7000N (700×10N), a stroke of 200mm, a speed of 110mm / s, and a motor power of 1.1KW (Y90S-4).

[0063] The reciprocating motor 29 can be model 57BYG250H-0601, a stepper motor with a torque of 0.6 N·m, a step angle of 1.8°, a speed of 3000 rpm, and a voltage of DC24V.

[0064] The above models are for reference only; specific implementation can be carried out using corresponding equipment as needed. In addition, the adhesive tape 16 should be selected as an adhesive tape that will not cause chemical damage to the fiber bundle.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
