Description

Technical Field

[0001] The present invention relates to a bed net winding and packaging machine, belonging to the technical field of bed net production equipment. Background Art

[0002] In the packaging process of bed nets, large mattresses need to be compressed and wound, then folded and packed; or the bed nets are first folded and then wound and packed, and then centrally packed and transported. The bed net winding and packaging machine is used to compress and wind the bed net into a cylindrical strip, which is beneficial for packing and transportation.

[0003] The prior art "Application No.: 2020225111610" discloses a bed net winding and packaging machine. After the mattress is pre-compressed by the upper pressing and pre-pressing mechanism, it is then transported to the winding and packaging mechanism for winding. Specifically, the mattress is transported to the lower conveyor belt through equipment such as a conveyor belt. The piston rod of the pre-pressing cylinder retracts, so that the upper conveyor belt is located at the front feeding station, where the distance between the upper conveyor belt and the lower conveyor belt is relatively large, and the mattress can be automatically fed between the upper conveyor belt and the lower conveyor belt; then the piston rod of the pre-pressing cylinder extends, and the upper conveyor belt and the lower conveyor belt rotate driven by independent drive motors, clamping and gradually compressing the mattress.

[0004] And it also includes a woven fabric conveying mechanism, which includes a placement rack for placing the woven fabric and a fabric guiding roller for guiding and transmitting the woven fabric. Specifically, the woven fabric for packaging is placed on the placement rack, and the woven fabric is guided along the first fabric guiding roller and the second fabric guiding roller, passes through the surface of the lower conveyor belt and is then placed on the surface of the main roller. The ventilation holes on the main roller suck the woven fabric, and the main roller rotates, so that the woven fabric is wound around the main roller for several circles, and the preparation of the woven fabric is completed.

[0005] The above prior art has the following defects: 1. After each winding and packaging is completed, it is necessary to stop the machine, and then manually place the woven fabric on the surface of the main roller again. Not only is the winding and packaging efficiency low, but also the workload of the users is increased; 2. It does not have an automatic tape sticking function. After the winding and packaging is completed, it is necessary to manually stick the tape on the surface of the woven fabric to prevent the bed net from bouncing open; 3. Since the bed net and the woven fabric are wound around the surface of the main roller, the bed net and the woven fabric are relatively tightly attached to the main roller, and the pushing plate may not be able to push the bed net and the woven fabric out of the main roller.

[0038] The winding shaft 6 is provided with chain guides 61 and material return profiles 62 distributed along its circumference. The chain guides 61 and material return profiles 62 are arranged crosswise, and one group of the material return profiles 62 is provided with magnets 63 used in conjunction with the pin assembly 5.

[0039] In this embodiment, preferably, Figure 2 As shown, a guide roller 9 is provided at the feed end of the feed pallet 1, and a cloth placing shaft 10 is provided on the side of the guide roller 9 away from the feed pallet 1 for placing packaging coils such as woven cloth and linen.

[0040] In this embodiment, preferably, Figure 2 As shown, the servo lower conveyor belt 2 is configured to be more closely fitted to the arc structure at the bottom of the winding shaft 6, so that the bed net can be automatically wound around the winding shaft 6 during the winding process to complete the winding work; the end of the servo lower conveyor belt 2 away from the feed pallet 1 is provided with a first servo module 11 for driving it to rise and fall; the bottom of the feed pallet 1 is provided with a second servo module 12 for driving it to move, and through the cooperation of the first servo module 11 and the second servo module 12, the pin assembly 5 is moved to the bottom of the winding shaft 6, and then the winding shaft 6 is rotated to make the magnet 63 dock with the pin assembly 5, and the movable pin of the pin assembly 5 is inserted into the magnet 63, thereby nailing the packaging coil to the winding shaft 6.

[0041] In this embodiment, preferably, Figures 9-10 As shown, movable supports 13 are fixedly provided on both sides of the feed pallet 1, and side panels 14 are fixedly provided on both sides of the servo upper conveyor belt 3. The side panels 14 are tiltedly arranged on the movable supports 13 through slide rail sliders, so that the servo upper conveyor belt 3 is tiltedly installed on the movable support 13. A first gear 15 driven to rotate by a motor is provided on the side panels 14. The first gear 15 is transmission-connected with a first rack 16, and the first rack 16 is fixedly arranged on the movable support 13. The first gear 15 is driven to rotate by the motor, so that the first gear 15 moves on the first rack 16, driving the side panels 14 to move, thereby driving the servo upper conveyor belt 3 to move tiltedly.

[0042] In this embodiment, preferably, Figures 11-12As shown, in the middle of the winding shaft 6, a winding motor 17 that drives its rotation is connected through gear transmission. Inside, a rotatable lead screw 18 is provided along its axial position. A lead screw nut 19 is assembled on the lead screw 18. One end of the lead screw nut 19 away from the hosting component 7 is connected through a synchronous belt to a lead screw motor 20 that drives its rotation.

[0043] In this embodiment, preferably, as Figures 13-14 shown, a rotatable unloading chain 64 is provided around the length direction of the chain guide rail 61.

During unloading, the lead screw motor 20 drives the lead screw 18 to rotate, causing the lead screw nut 19 to move relatively, driving the unloading chain 64 to operate, and pushing the bed net wrapped on the winding shaft 6 out of the winding shaft 6.

[0044] In this embodiment, preferably, as Figures 15-16 shown, the hosting component 7 includes a moving plate 71 and a centering shaft 72.

A bearing matching the centering shaft 72 is provided inside the octagonal end cover 66. During wrapping, the second cylinder 75 drives the centering shaft 72 to insert into the bearing inside the octagonal end cover 66, and the centering shaft 72 supports the winding shaft 6, making the rotation of the winding shaft 6 more stable; during unloading, the second cylinder 75 drives the centering shaft 72 to leave the bearing inside the octagonal end cover 66, and then the first cylinder 73 drives the moving plate 71 to move, so that the moving plate 71 leaves the discharging area of the winding shaft 6, avoiding the moving plate 71 from hindering the discharging.

[0046] The specific working principle of the present invention:

[0047] 1. Coil preparation: Place the coil used for packaging on the cloth-releasing shaft 10. Initially, manually pull the end of the coil to the discharge end of the feeding pallet 1 and fix it. Then, use the pinning component 5 to nail the coil onto the magnet 63 of the winding shaft 6. The winding shaft 6 rotates to wind the coil around the winding shaft 6 for several turns. Then, the pinning component 5 resets, and the coil preparation is completed.

[0048] 2. Loading and pre-compression: Convey the bed net to the feeding pallet 1 through equipment such as a conveyor belt. The motor drives the first gear 15 to move obliquely upward along the first rack 16, causing the servo upper conveyor belt 3 to move obliquely upward, so that the servo upper conveyor belt 3 is located at the front-end feeding station. Here, the distance between the servo upper conveyor belt 3 and the feeding pallet 1 is relatively large, and the bed net can enter between the feeding pallet 1 and the servo upper conveyor belt 3 independently. Then, the motor drives the first gear 15 to move obliquely downward along the first rack 16, causing the servo upper conveyor belt 3 to move obliquely downward, clamping and gradually compressing the bed net.

[0049] 3. Winding and packaging: The servo upper conveyor belt 3 moves obliquely downward. Under the clamping and conveying of the servo upper conveyor belt 3, the bed net is pre-compressed and conveyed between the servo lower conveyor belt 2 and the winding shaft 6. The winding motor 17 drives the winding shaft 6 to rotate for winding and packaging. Since when the winding shaft 6 rotates, it will drive the discharge chain 64 on the chain guide 61 to rotate, thus driving the screw nut 19 to rotate. In order for the screw nut 19 not to move relatively on the screw rod 18 when it rotates, the screw rod 18 also needs to rotate at the same speed and in the same direction as the screw nut 19. That is, during winding, the winding motor 17 and the screw rod motor 20 need to rotate at the same speed and in the same direction, so that the screw nut 19 will not move and will not drive the discharge chain 64 to operate, avoiding the phenomenon of winding and discharging at the same time.

[0050] 4. Cutting the packaging coil: After the winding and packaging are completed, the pinning component 5 rises through the packaging coil again, and then the cutting knife component 60 cuts the packaging coil between the servo lower conveyor belt 2 and the feeding pallet 1.

[0051] 5. Sticking tape: After cutting the packaging coil, the winding shaft 6 continues to rotate for several turns to wind the excess packaging coil around the bed net. Then, the tape sticking mechanism 8 descends, and the tape pressing wheel of the tape sticking mechanism 8 sticks the tape onto the packaging coil around the outer periphery of the bed net. After winding for several turns, the tape is cut by the cutter of the tape sticking mechanism 8 to complete the tape sticking work.

[0052] 6. Discharging: Drive the centering shaft 72 to leave the inner bearing of the octagonal end cover 66 through the second cylinder 75, and then drive the moving plate 71 to move through the first cylinder 73, so that the moving plate 71 leaves the discharge area of the winding shaft 6 to avoid the moving plate 71 hindering the discharge. Then, drive the screw rod 18 to rotate through the screw rod motor 20, causing the screw nut 19 to move relatively, driving the discharge chain 64 to operate, and pushing the bed net wrapped on the winding shaft 6 out of the winding shaft 6.

[0053] After the material is returned, since the pin assembly 5 is in a state of being raised and passed through the packaging coil when the packaging coil is just cut, it is only necessary to move the pin assembly 5 to the bottom of the winding shaft 6 through the first servo module 11 and the second servo module 12, and then rotate the winding shaft 6 to make the magnet 63 coincide with the pin assembly 5, and insert the movable pin of the pin assembly 5 into the magnet 63, so that the packaging coil can be automatically nailed to the winding shaft 6, and there is no need to manually pull the packaging coil and place it on the winding shaft 6, thereby realizing automatic and continuous feeding of the packaging coil.
