Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of packaging, in particular to an automatic non-woven fabric roll packaging device. BACKGROUND

[0002] Non-woven fabric, also known as non-woven cloth or non-woven cloth, is a sheet, web or pad made of oriented or random fibers by friction, adhesion, bonding or a combination of these methods, which has the characteristics of high strength, good durability, strong filtration and large-scale production, and is widely used in medical, health, agricultural, packaging, clothing and construction industries.

[0003] The existing automatic non-woven fabric roll packaging device with publication number CN119117348A can make the film evenly spread and then wind on the non-woven fabric roll, avoid affecting the packaging quality and causing film waste due to film folding and winding, and can also compact the film on the upper and lower end surfaces of the non-woven fabric roll through the upper and lower film pressing plates. Because the non-woven fabric roll is not an ideal cylindrical structure, the rod structure at the shaft center will be affected by the centrifugal force of the winding drum when the non-woven fabric roll is rotated, thereby having a tendency to tilt to the side. At this time, the structure of the non-woven fabric roll away from the side of the opening plate will shake, thereby causing the problem of unable to normally package, so improvement is needed. SUMMARY

[0004] In view of the problem that the existing technology is prone to cause the non-woven fabric roll to shake when rotating the non-woven fabric roll, the technical solution adopted by the present application is: an automatic non-woven fabric roll packaging device, comprising: A control device is provided at the front end of the control device, and a film placement area is provided at the bottom of the control device. A docking base plate is provided at the top of the docking base plate, and a non-woven fabric roll is provided. The control device comprises: A vertical fixed box is provided at the shaft center of the vertical fixed box, and a mechanical bending arm is connected to the vertical fixed box. A pressure control top cylinder is provided at the front end of the mechanical bending arm, and the outer surface of the pressure control top cylinder is inserted into the pressure control top cylinder. A torque insertion cylinder is provided at the bottom of the inner cavity of the pressure control top cylinder, and the top end of the torque insertion cylinder is inserted into the torque insertion cylinder. The torque insertion cylinder comprises: A guide cylinder shell is provided at the top of the inner wall of the guide cylinder shell, and the bottom end of the outer surface of the torque insertion cylinder is inserted into the guide cylinder shell. The inner part of the guide cylinder shell can be pressurized through the hole at the shaft center of the torque insertion cylinder. A sliding cylinder shell is connected to the inner wall of the guide cylinder shell. An infrared inner cylinder is provided in the inner part of the sliding cylinder shell. Two extension devices are provided, one on the outer surface of the guide shell and the other on the outer surface of the sliding shell.

[0005] Furthermore, the extended device includes: A drainage and pressurizing cylinder, wherein protective mesh covers are symmetrically arranged on the upper and lower sides of the outer surface of the drainage and pressurizing cylinder; A compression rod, the end of which is inserted into the inner cavity of the drainage and pressurization cylinder through an air port; The rough-surfaced clamp is inserted into the middle of the inner wall of the compression support rod at the end away from the flow-inducing and pressurizing cylinder. The outer surface of the rough-surfaced clamp is pressed against the axis of the inner wall of the non-woven fabric roll. The flow-inducing and pressurizing cylinder pressurizes the air into the interior of the compression support rod, thereby achieving the effect of pushing the rough-surfaced clamp and making the rough-surfaced clamp fit against the inner wall of the non-woven fabric roll.

[0006] Furthermore, the infrared inner cylinder includes: The signal tube has its outer surface inserted into the inner wall of the sliding cylinder shell. Infrared detectors are evenly arranged on the outer surface of the signal tube, and the outer surface of the infrared detectors extends to the outside of the sliding cylinder shell through vertical grooves. The signal tube monitors the distance from the outer surface of the sliding cylinder shell to the inner wall of the nonwoven fabric roll through the infrared detectors on its side. The signal terminals are symmetrically arranged at the upper and lower ends of the signal tube. The signal tube controls the upper and lower drainage and pressurization tubes through the signal terminals. The signal tube controls the upper and lower drainage and pressurization tubes to work through the signal terminals on the upper and lower sides respectively.

[0007] Furthermore, the film placement area includes: An embedded sliding plate, wherein the two sides of the outer surface of the embedded sliding plate are slidably connected to the axis of the inner wall of the vertical fixed box via active pulleys; A horizontal support plate, the back of which is inserted into the middle of the inner cavity of the embedded sliding plate; The motor base is located in the middle of the inner cavity of the horizontal support plate and is used to place the winding film. The shaft at the bottom end of the winding film is inserted into the interior of the motor base, and the motor base controls the rotation of the shaft cylinder of the winding film.

[0008] Furthermore, the film placement area also includes: The biasing plates are symmetrically arranged on the left and right sides of the upper surface of the horizontal support plate, and the bottom end of the biasing plate's rotating shaft is inserted into the inner cavity of the horizontal support plate. The rotary sleeve has its rear end slidably connected to the inner wall of the vertical fixed box via parallel sliding grooves, and the top end of the deflection plate shaft is inserted into the inner cavity of the rotary sleeve. A loop spring is installed inside the rotary sleeve. When the deflection plate deflects, it will store energy in the loop spring. Therefore, under normal circumstances, the deflection plates on both sides will deflect towards the side closer to the wound film. An inverted motor is provided, wherein a feeding roller is inserted into the outer surface of the inverted motor shaft, and the outer surface of the inverted motor is fixedly connected to the outer surface of the deflection plate via a connecting rod, and the outer surface of the feeding roller is rotatably connected to the front end of the deflection plate.

[0009] Furthermore, the docking chassis includes: A fixed chassis is provided with a docking plug at the center of the fixed chassis, and the bottom end of the sliding cylinder shell is inserted into the inner wall of the docking plug; The mating bearing has sliding balls evenly distributed on its upper surface, and its bottom is rotatably connected to the center of the upper surface of the fixed chassis.

[0010] Furthermore, the docking chassis also includes: The pressure-controlled bottom cylinder has airflow ports evenly distributed on its top, and its bottom is inserted into the center of the upper surface of the fixed chassis via a slot. The sliding sleeve has its inner wall fitted onto the upper part of the outer surface of the pressure control cylinder, and the top of the sliding sleeve is pressed against the bottom end of the nonwoven fabric roll. The top of the sliding sleeve is located in the gap between the bottom end of the nonwoven fabric roll and the mating bearing. Due to the supporting effect of the sliding balls, the sliding sleeve can slide up and down within a certain range.

[0011] The beneficial effects of this invention are as follows: 1. This device can insert a segmented, two-section cylindrical shell into the axis of a vertically placed nonwoven fabric roll. By extending the sliding cylindrical shell, the upper and lower extension devices are moved to a position close to the end of the nonwoven fabric roll, thereby stabilizing the overall position of the nonwoven fabric roll and preventing it from shaking due to centrifugal force during the winding process. This ensures that the nonwoven fabric roll always rotates around its axis and prevents the wound film from bulging and overlapping due to the eccentric shaking of the nonwoven fabric roll.

[0012] 2. The extension device uses a textured clamping plate to press tightly against the cylinder wall at the center of the nonwoven fabric roll, thus connecting the nonwoven fabric roll. To prevent excessive pressure on the nonwoven fabric roll and deformation of the cylinder wall, the pressure-regulating cylinder adjusts the pressure of the textured clamping plate through pressure control. During operation, the pressure-regulating cylinder, through feedback from the signal cylinder, can promptly enhance the fixing effect of the textured clamping plate when the nonwoven fabric roll experiences slight shaking, thereby achieving dynamic adjustment and correcting the nonwoven fabric roll to a stable rotating state, giving the packaging process a certain degree of intelligent adjustment.

[0013] 3. The film roll for feeding is set on a horizontal pallet, enabling stable vertical sliding motion during packaging to completely wrap the outer surface of the nonwoven fabric roll. Since the roll is surrounded by deflecting plates on both sides inside the horizontal pallet, and the film at its end is driven closer to the nonwoven fabric roll by the rotating feeding roller, the film roll will not separate from the horizontal pallet due to centrifugal force or the pulling force of the film during feeding. The speed of the film roll is adjusted by the motor base to match the speed of the nonwoven fabric roll, avoiding the problem of the film tape being torn due to the film roll feeding speed being too slow.

[0014] 4. When the nonwoven fabric roll is wrapped and packaged, its bottom contacts the ball bearings on the upper part of the mating bearing. Therefore, the frictional resistance during rotation is small, which prevents the fabric edge at the bottom of the nonwoven fabric roll from getting stained and dirty due to frictional rotation. The sliding sleeve can squeeze the reserved film strip closer to the bottom of the nonwoven fabric roll, thereby protecting the bottom edge of the nonwoven fabric roll. At the same time, it prevents the starting end of the film strip from sticking up from the outside of the nonwoven fabric roll, which would cause the edge to stick up. This makes the packaged nonwoven fabric roll smoother overall. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Example 1, please refer to Figures 1-6 This invention provides a technical solution: an automatic packaging device for nonwoven fabric rolls, comprising: Control device 1, a twisting device 3 is installed at the front end of control device 1, and a film placement area 2 is installed at the bottom of control device 1; The docking chassis 4 has a non-woven fabric roll 5 on its top. Control device 1 includes: A vertical fixing box 11 is provided, and a mechanical curved arm 12 is slidably connected at the axis of the vertical fixing box 11. The pressure-controlled top cylinder 13 is inserted into the front end of the mechanical bending arm 12 on its outer surface. The torque insert 14 is located at the bottom of the inner cavity of the pressure control top cylinder 13 and is inserted into the top of the torsion device 3; The torsion device 3 includes: The top of the inner wall of the guide cylinder shell 31 is inserted into the bottom of the outer surface of the torque insert 14. The pressure control top cylinder 13 can pressurize the inside of the guide cylinder shell 31 through the hole at the axis of the torque insert 14. The sliding cylindrical shell 32 is slidably connected to the inner wall of the guide cylindrical shell 31; The infrared inner cylinder 33 is disposed inside the sliding cylinder shell 32; There are two extension devices 6, which are respectively installed on the outer surface of the guide cylinder shell 31 and the outer surface of the sliding cylinder shell 32.

[0019] Extended device 6 includes: The drainage and pressurizing cylinder 61 has protective mesh covers 62 symmetrically arranged on the upper and lower sides of its outer surface; Compression rod 63, the end of compression rod 63 is inserted into the inner cavity of the drainage and pressurization cylinder 61 through an air port; The rough-surfaced clamp 64 is inserted into the middle of the inner wall of the compression support rod 63 away from the flow-inducing and pressurizing cylinder 61. The outer surface of the rough-surfaced clamp 64 is pressed against the axis of the inner wall of the non-woven fabric roll 5. The flow-inducing and pressurizing cylinder 61 pressurizes the air into the interior of the compression support rod 63, thereby achieving the effect of pushing the rough-surfaced clamp 64 and making the rough-surfaced clamp 64 fit against the inner wall of the non-woven fabric roll 5.

[0020] Infrared inner cylinder 33 includes: Signal tube 331, the outer surface of signal tube 331 is inserted into the inner wall of sliding cylinder shell 32, infrared detectors 332 are evenly arranged on the outer surface of signal tube 331, and the outer surface of infrared detectors 332 extends to the outside of sliding cylinder shell 32 through vertical grooves. Signal tube 331 monitors the distance from the outer surface of sliding cylinder shell 32 to the inner wall of nonwoven fabric roll 5 through the infrared detectors 332 on the side. Signal terminals 333 are symmetrically arranged at the upper and lower ends of signal cylinder 331. Signal cylinder 331 controls the upper and lower drainage and pressurizing cylinders 61 through signal terminals 333. Signal cylinder 331 controls the upper and lower drainage and pressurizing cylinders 61 to work through signal terminals 333 on the upper and lower sides respectively.

[0021] The nonwoven fabric roll 5 to be wrapped is placed vertically at the center of the top of the docking base 4. Then, the vertical fixing box 11 inserts the twisting device 3 vertically into the roll at the center of the nonwoven fabric roll 5 by sliding the mechanical bending arm 12. The twisting device 3 is adjusted by the mechanical bending arm 12 so that the twisting device 3 is perpendicular to the docking base 4. Then, the pressure control top cylinder 13 pressurizes the inside of the guide cylinder shell 31 through the torque insertion cylinder 14, so that the sliding cylinder shell 32 slides down along the inner wall of the guide cylinder shell 31 under pressure and connects with the docking plug 44 at the bottom. Then, the extension device 6 outside the guide cylinder shell 31 and the extension device 6 outside the sliding cylinder shell 32 are activated to fix the center of the nonwoven fabric roll 5.

[0022] The pressure-inducing cylinder 61 draws air from the outside through the protective mesh covers 62 on the upper and lower sides, and then pressurizes the air to each compression rod 63, causing the expanded compression rod 63 to push the rough-surface clamping plate 64 to fit against the inner wall of the non-woven fabric roll 5, thereby achieving the effect of clamping and fixing the non-woven fabric roll 5 from the inside out.

[0023] The stretch film roll is vertically inserted into the axis of the film placement area 2, and then its end film is wrapped around the bottom of the nonwoven fabric roll 5. Then, the film is continuously fed through the film placement area 2. At the same time, the torque insert 14 drives the nonwoven fabric roll 5 to rotate through the torsion device 3. The film placement area 2 drives the stretch film roll to move from top to bottom, so that the outer surface of the nonwoven fabric roll 5 is completely wrapped with protective film.

[0024] The film placement area 2 moves back and forth in the vertical direction to ensure that the outer surface of the nonwoven fabric roll 5 is wrapped with multiple layers of protective film. Then the film is cut off to release the clamping effect of the expansion device 6 on the nonwoven fabric roll 5. Then the sliding cylinder shell 32 is contracted and the guide cylinder shell 31 is pulled out by the mechanical bending arm 12 to remove the nonwoven fabric roll 5.

[0025] When the nonwoven fabric roll 5 is twisted, if the nonwoven fabric roll 5 shows slight signs of shaking, the nonwoven fabric roll 5 will exert a squeezing force on the rough-surface clamp 64 away from the tilted side. The signal cylinder 331 detects a change in distance through the infrared detector 332, and thus sends a pressure signal to the relaxed drainage pressure cylinder 61 through the signal ends 333 on both sides. Subsequently, the rough-surface clamp 64 re-squeezes the inner wall of the nonwoven fabric roll 5, thereby correcting and fixing the upper and lower sides of the inner wall of the nonwoven fabric roll 5 near the end. Therefore, the nonwoven fabric roll 5 will not tilt when it is rotated.

[0026] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the film placement area 2 includes: The embedded slide plate 21 has two sides of its outer surface that are slidably connected to the axis of the inner wall of the vertical fixed box 11 via active pulleys. The back of the horizontal support plate 22 is inserted into the middle of the inner cavity of the embedded sliding plate 21. The motor base 23 is located in the middle of the inner cavity of the horizontal support plate 22 and is used to place the winding film. The shaft at the bottom end of the winding film is inserted into the interior of the motor base 23, and the motor base 23 controls the shaft cylinder of the winding film to rotate.

[0027] The film placement area 2 also includes: The biasing plate 24 is symmetrically arranged on the left and right sides of the upper surface of the horizontal support plate 22, and the bottom end of the pivot of the biasing plate 24 is inserted into the inner cavity of the horizontal support plate 22. The rotary sleeve 25 has its rear end slidably connected to the inner wall of the vertical fixed box 11 via parallel sliding grooves, and the top end of the deflection plate 24's rotating shaft is inserted into the inner cavity of the rotary sleeve 25. A loop spring is provided inside the rotary sleeve 25. When the deflection plate 24 deflects, it will store energy in the loop spring. Therefore, under normal circumstances, the deflection plates 24 on both sides will deflect towards the side closer to the wound film. An inverted motor 26 has a feeding roller 27 inserted into the outer surface of its shaft. The outer surface of the inverted motor 26 is fixedly connected to the outer surface of the deflection plate 24 via a connecting rod, and the outer surface of the feeding roller 27 is rotatably connected to the front end of the deflection plate 24.

[0028] The docking chassis 4 includes: A fixed chassis 41 is provided with a docking plug 44 at the axis of the fixed chassis 41, and the bottom end of the sliding cylinder shell 32 is inserted into the inner wall of the docking plug 44. The mating bearing 45 has sliding balls evenly distributed on its upper surface, and its bottom is rotatably connected to the axis of the upper surface of the fixed base 41.

[0029] Chassis 4 also includes: The pressure control bottom cylinder 42 has airflow ports evenly distributed on its top, and its bottom is inserted into the center of the upper surface of the fixed chassis 41 through a slot. The sliding sleeve 43 has its inner wall fitted onto the upper part of the outer surface of the pressure control bottom cylinder 42, and the top of the sliding sleeve 43 is pressed against the bottom end of the nonwoven fabric roll 5. The top of the sliding sleeve 43 is located in the gap between the bottom end of the nonwoven fabric roll 5 and the mating bearing 45. Due to the supporting effect of the sliding balls, the sliding sleeve 43 can slide up and down within a certain range.

[0030] After the stretch film roll is vertically inserted into the motor base 23, the front end of the film is pulled out from between the feeding rollers 27 held on both sides. Then, the inverted motor 26 controls the feeding rollers 27 to rotate, which, together with the effect of the motor base 23 twisting the stretch film roll, achieves the effect of releasing the film from the outer surface of the stretch film roll. When the winding work stops, the feeding rollers 27 and the motor base 23 stop rotating at the same time. Since the nonwoven fabric roll 5 is still rotating at this time, and the feeding rollers 27 hold the film through the spring action of the rotary sleeve 25, the film is torn at this time, thus stopping the winding work. When winding the nonwoven fabric roll 5 again, the feeding rollers 27 release the end of the film. Since the embedded sliding plate 21 drives the film placement area 2 to slide vertically, the biasing rotating plates 24 located on both sides also slide synchronously under the guidance of the rotary sleeve 25, so the film can be torn at any position, thus stopping the winding work at any time.

[0031] The nonwoven fabric roll 5 is placed vertically on the docking base 4, and its bottom contacts the balls on the upper surface of the docking bearing 45. Therefore, when the nonwoven fabric roll 5 rotates, its bottom end will roll and rub against the balls, which greatly reduces the frictional resistance encountered when the nonwoven fabric roll 5 rotates, thus avoiding the problem of slippage between the nonwoven fabric roll 5 and the extension device 6. When the film is wrapped around the bottom of the nonwoven fabric roll 5, the bottom edge of the film can be inserted into the position between the upper surface of the docking bearing 45 and the bottom of the nonwoven fabric roll 5. Then, the pressure control cylinder 42 pressurizes the inside of the sliding sleeve 43, causing the sliding sleeve 43 to rise and squeeze the bottom of the film closer to the bottom of the nonwoven fabric roll 5, thereby sealing the bottom side of the nonwoven fabric roll 5.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
