Description

Technical Field

[0001] This utility model relates to a bed net rolling and wrapping machine, belonging to the technical field of bed net production equipment. Background Technology

[0002] In the packaging process of mattresses, large mattresses need to be compressed and rolled up, then folded in half and packed; or the mattresses can be folded in half first, then rolled up and packaged, and then centrally packed and transported. Mattress rolling machines are used to compress and roll mattresses into cylindrical strips, which facilitates packing and transportation.

[0003] The prior art, patent application number 2020225111610, discloses a mattress rolling machine. The mattress is pre-compressed by an upper pre-compression mechanism before being conveyed to a rolling mechanism for rolling. Specifically, the mattress is transported to the lower conveyor belt via a conveyor belt or similar equipment. The piston rod of the pre-compression cylinder retracts, positioning the upper conveyor belt at the front feeding station. At this station, the distance between the upper and lower conveyor belts is relatively large, allowing the mattress to be fed between them autonomously. Then, the piston rod of the pre-compression cylinder extends, and the upper and lower conveyor belts rotate under the drive of independent drive motors, clamping and gradually compressing the mattress.

[0004] It also includes a woven fabric conveying mechanism, which includes a placement rack for placing the woven fabric and guide rollers for guiding and conveying the woven fabric. Specifically, the woven fabric for packaging is placed on the placement rack, and then the woven fabric is moved along the first guide roller and the second guide roller, passing over the surface of the lower conveyor belt and then placed on the surface of the main roller. The ventilation holes on the main roller hold the woven fabric in place, and the main roller rotates, causing the woven fabric to wrap around the main roller several times, thus completing the preparation of the woven fabric.

[0005] The aforementioned existing technology has the following drawbacks: 1. After each wrapping is completed, the machine needs to be stopped, and the woven fabric needs to be manually placed back onto the surface of the main roller. This not only results in low wrapping efficiency but also increases the workload of the operators; 2. It does not have an automatic tape application function. After wrapping, tape needs to be manually applied to the surface of the woven fabric to prevent the bed net from springing open; 3. Since the bed net and woven fabric are wrapped around the surface of the main roller, they are tightly attached to the main roller, and the pusher plate may not be able to push the bed net and woven fabric out of the main roller.

[0006] Therefore, the research objective of this utility model is to provide a bed net wrapping machine that automatically feeds and applies adhesive tape to roll materials and stably unloads them. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this utility model provides a bed net rolling machine. Through the cooperation between the pin assembly on the feeding tray and the magnet on the winding shaft, the packaging roll is nailed to the winding shaft, allowing the roll to rotate with the winding shaft, thereby achieving a continuous feeding effect.

[0017] Furthermore, an eight-claw end cap is fixedly provided at one end of the take-up shaft near the hosting assembly, and a bearing matching the centering shaft is provided on the inner side of the eight-claw end cap.

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-16 Further analysis of this utility model is then conducted.

[0037] like Figure 1-8As shown, a bed net rolling machine includes a feeding tray 1, the discharge end of which is connected to a servo lower conveyor belt 2, and an inclined servo upper conveyor belt 3 is provided above it. The end of the feeding tray 1 near the servo lower conveyor belt 2 is also provided with a pin insertion assembly 5 and a cutter assembly 6.

The discharge end of the winding shaft 6 is connected to a support assembly 7 for supporting its rotation, and a liftable adhesive tape mechanism 8 is provided above it.

[0038] The take-up shaft 6 is provided with chain guide rails 61 and ejector profiles 62 distributed along its circumference. The chain guide rails 61 and ejector profiles 62 are arranged in a cross pattern. One group of ejector profiles 62 is provided with magnets 63 distributed on it for use with the pin assembly 5.

[0039] In this embodiment, preferably, as follows: Figure 2 As shown, the feeding end of the feeding tray 1 is provided with a guide roller 9, and the side of the guide roller 9 away from the feeding tray 1 is provided with a cloth-laying shaft 10 for placing packaging rolls such as woven cloth and linen.

[0040] In this embodiment, preferably, as follows: Figure 2 As shown, the servo lower conveyor belt 2 is configured with an arc-shaped structure that fits more closely to the bottom of the take-up shaft 6, so that the bed net can automatically wind onto the take-up shaft 6 during the wrapping process to complete the wrapping work; the end of the servo lower conveyor belt 2 away from the feed tray 1 is provided with a first servo module 11 that drives its lifting and lowering; the bottom of the feed tray 1 is provided with a second servo module 12 that drives its movement. Through the cooperation of the first servo module 11 and the second servo module 12, the pin insertion assembly 5 is moved to the bottom of the take-up shaft 6, and then the take-up shaft 6 is rotated so that the magnet 63 is connected to the pin insertion assembly 5, and the movable pin of the pin insertion assembly 5 is inserted into the magnet 63, thereby nailing the packaging roll onto the take-up shaft 6.

[0041] In this embodiment, preferably, as follows: Figures 9-10 As shown, movable supports 13 are fixedly provided on both sides of the feed tray 1, and side plates 14 are fixedly provided on both sides of the servo upper conveyor belt 3. The side plates 14 are inclinedly mounted on the movable supports 13 via slide rail sliders, thereby tilting the servo upper conveyor belt 3 onto the movable supports 13. The side plates 14 are provided with a first gear 15 driven to rotate by a motor. The first gear 15 is connected to a first rack 16, which is fixedly mounted on the movable supports 13. The first gear 15 is driven to rotate by a motor, causing the first gear 15 to move on the first rack 16, thereby driving the side plates 14 to move, and thus causing the servo upper conveyor belt 3 to move tilted.

[0042] In this embodiment, preferably, as follows: Figure 11-12As shown, the winding shaft 6 is connected to a winding motor 17 that drives its rotation via gear transmission in the middle. A rotatable lead screw 18 is provided inside the shaft along its axis. A lead screw nut 19 is mounted on the lead screw 18. The end of the lead screw 18 away from the support assembly 7 is connected to a lead screw motor 20 that drives its rotation via a synchronous belt transmission.

[0043] In this embodiment, preferably, as follows: Figure 13-14 As shown, a rotatable unloading chain 64 is arranged around the chain guide rail 61 along its length. Both ends of the unloading chain 64 are rotatably mounted on both ends of the chain guide rail 61 via sprockets. The inner side of the unloading chain 64 is fixedly connected to the lead screw nut 19 via a connecting plate, and the outer side is fixedly connected to a synchronization ring 65 via a connecting rod. The function of the synchronization ring 65 is to connect the outer sides of the unloading chains 64 on each set of chain guide rails 61 in series. During unloading, the lead screw 18 is driven to rotate by the lead screw motor 20, causing the lead screw nut 19 to move relative to the lead screw, which in turn drives the unloading chain 64 to rotate, pushing the bed netting wound on the take-up shaft 6 out of the take-up shaft 6.

[0044] In this embodiment, preferably, as follows: Figure 15-16 As shown, the hosting component 7 includes a movable plate 71 and a centering shaft 72. The movable plate 71 is movably mounted on the frame of the wrapping machine via a slide rail slider. The two ends of the movable plate 71 are connected to a first cylinder 73 that drives its movement. The centering shaft 72 is movably disposed in the middle of the movable plate 71 via a linear bearing. The end of the shaft away from the take-up shaft 6 is connected to a cylinder mounting plate 74. The two ends of the cylinder mounting plate 74 are connected to a second cylinder 75 that drives the centering shaft 72 to move. The second cylinder 75 is fixedly mounted on the movable plate 71.

[0045] In this embodiment, preferably, as follows: Figure 6 As shown, an eight-claw end cap 66 is fixedly provided at one end of the take-up shaft 6 near the hosting assembly 7. The inner side of the eight-claw end cap 66 is provided with a bearing that matches the centering shaft 72. During winding, the centering shaft 72 is driven by the second cylinder 75 to insert into the bearing inside the eight-claw end cap 66, and the centering shaft 72 supports the take-up shaft 6, making the rotation of the take-up shaft 6 more stable. During unwinding, the centering shaft 72 is driven by the second cylinder 75 to leave the bearing inside the eight-claw end cap 66, and then the moving plate 71 is driven by the first cylinder 73 to move, so that the moving plate 71 leaves the discharge area of ​​the take-up shaft 6, avoiding the moving plate 71 from obstructing the discharge.

[0046] The specific working principle of this utility model is as follows:

[0047] 1. Preparation of the roll material: Place the roll material for packaging on the fabric feeding shaft 10. Initially, the end of the roll material needs to be manually pulled to the discharge end of the feed tray 1 and fixed. Then, the roll material is nailed to the magnet 63 of the take-up shaft 6 by the pin assembly 5. The take-up shaft 6 rotates, so that the roll material is wound around the take-up shaft 6 several times. Then the pin assembly 5 is reset, and the roll material preparation is completed.

[0048] 2. Feeding and pre-compression: The bed net is conveyed to the feeding tray 1 by a conveyor belt and other equipment. The motor drives the first gear 15 to move upward along the first rack 16, causing the servo upper conveyor belt 3 to move upward. The servo upper conveyor belt 3 is positioned at the front feeding station. At this point, the distance between the servo upper conveyor belt 3 and the feeding tray 1 is relatively large, allowing the bed net to enter between the feeding tray 1 and the servo upper conveyor belt 3 autonomously. Then, the motor drives the first gear 15 to move downward along the first rack 16, causing the servo upper conveyor belt 3 to move downward, clamping and gradually compressing the bed net.

[0049] 3. Bundling: The servo upper conveyor belt 3 moves downward at an incline. 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 take-up shaft 6. The take-up motor 17 drives the take-up shaft 6 to rotate for bundling. When the take-up shaft 6 rotates, it will drive the unloading chain 64 on the chain guide 61 to rotate, thereby driving the lead screw nut 19 to rotate. In order to prevent the lead screw nut 19 from moving relative to the lead screw 18 when it rotates, the lead screw 18 must also keep rotating at the same speed and in the same direction as the lead screw nut 19. That is, during winding, the take-up motor 17 and the lead screw motor 20 need to be kept rotating at the same speed and in the same direction so that the lead screw nut 19 will not move and will not drive the unloading chain 64 to operate, thus avoiding the phenomenon of winding and unloading at the same time.

[0050] 4. Cutting the packaging roll: After the packaging is completed, the pin assembly 5 rises again and passes through the packaging roll. Then, the cutting assembly 60 cuts the packaging roll between the servo lower conveyor belt 2 and the feed tray 1.

[0051] 5. Applying adhesive tape: After cutting the packaging roll, the take-up shaft 6 continues to rotate several times to wrap the excess packaging roll around the bed net. Then, the adhesive tape mechanism 8 descends, and the tape pressure roller of the adhesive tape mechanism 8 places the tape on the packaging roll around the outside of the bed net. After wrapping several times, the tape is cut by the cutter of the adhesive tape mechanism 8 to complete the adhesive tape application.

[0052] 6. Unloading: The second cylinder 75 drives the centering shaft 72 to leave the inner bearing of the eight-claw end cover 66, and the first cylinder 73 drives the moving plate 71 to move away from the discharge area of ​​the take-up shaft 6, so as to avoid the moving plate 71 from obstructing the discharge; then the lead screw motor 20 drives the lead screw 18 to rotate, so that the lead screw nut 19 moves relative to the lead screw, which drives the unloading chain 64 to run, pushing the bed net wound on the take-up shaft 6 out of the take-up shaft 6.

[0053] After the unloading is completed, since the pin assembly 5 was in the raised state when the packaging roll was cut, it is only necessary to move the pin assembly 5 to the bottom of the take-up shaft 6 through the first servo module 11 and the second servo module 12, and then rotate the take-up 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 roll can be automatically nailed to the take-up shaft 6. There is no need to manually pull the packaging roll onto the take-up shaft 6, thus realizing automatic continuous feeding of the packaging roll.
