Description

Technical Field

[0001] This invention relates to the field of shower curtain manufacturing technology, specifically a shower curtain folding and packaging equipment. Background Technology

[0002] Shower curtains, as a common bathroom product, typically involve fabric cutting, printing, folding, and packaging. Among these, folding is crucial for ensuring a neat appearance and facilitating packaging and storage. Currently, shower curtain folding in the industry is still primarily manual, resulting in high labor intensity, low production efficiency, and poor folding consistency. A few companies use semi-automated equipment to assist with folding, but this requires frequent manual intervention and is difficult to meet the demands of large-scale production.

[0003] With the growth of market demand, automated folding packaging equipment has gradually become the direction of industry upgrading. However, existing automated shower curtain folding equipment generally has the following shortcomings: First, the structure is relatively complex, and the equipment requires many parts. For example, using mechanical force components such as blades to fold bed sheets can cause irreversible damage to the shower curtain; Second, the folding function is limited, usually only able to achieve unidirectional folding (such as longitudinal or transverse), making it difficult to meet the multi-dimensional folding requirements of shower curtains; Third, the material transmission stability is poor, and the shower curtain is prone to deviation, wrinkling, or jamming during transmission, affecting the folding accuracy; Fourth, it lacks adaptive adjustment capabilities, has insufficient compatibility with shower curtains of different sizes or materials, and its application range is limited. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a shower curtain folding and packaging equipment with high working efficiency, good equipment stability and convenient operation.

[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows: a shower curtain folding and packaging device, comprising an equipment box, a feeding conveyor belt, a transition conveyor belt, a split conveyor belt, a guiding assembly, a guiding roller, and a discharging conveyor belt. The feeding conveyor belt is fixedly installed inside the equipment box for conveying the unfolded shower curtain into the equipment box for folding. One end of the feeding conveyor belt extends out of the equipment box, and both sides are fixedly installed on support plates. One end of each support plate is fixedly connected to the outer wall of the equipment box. A transition conveyor belt is fixedly installed inside the equipment box below the feeding conveyor belt for relative conveying of the first folded shower curtain. One end of the transition conveyor belt is connected to the feeding conveyor belt. One end of the transition conveyor belt is close to the other end of the split conveyor belt. The split conveyor belt is fixedly installed in the equipment box below the transition conveyor belt and is used to transport the shower curtain that has been folded again. The split conveyor belt is equipped with a material guide assembly to facilitate the horizontal folding operation of the shower curtain. The two ends of the material guide assembly are fixedly connected to the inner wall of the equipment box. The bottom of the equipment box below the material guide assembly is fixedly connected to a discharge box. One end of the discharge box extends out of the equipment box and is provided with a discharge port. A material guide roller is rotatably connected in the discharge box. A discharge conveyor belt is fixedly installed in the discharge box below the material guide roller. After being folded horizontally again, the shower curtain is discharged to the packaging operation.

[0006] A first pushing component is fixedly installed in the equipment box located on one side of the feeding conveyor belt and the transition conveyor belt. When the shower curtain exits the feeding conveyor belt and its middle part is located between the feeding conveyor belt and the transition conveyor belt, the first pushing component folds the shower curtain longitudinally and pushes the folded part between the feeding conveyor belt and the transition conveyor belt, thereby folding the shower curtain and conveying it along the transition conveyor belt. A second pushing component is fixedly installed in the equipment box located on one side of the transition conveyor belt and the split conveyor belt. After the shower curtain is folded longitudinally for the first time, it exits the transition conveyor belt and its middle part is located between the transition conveyor belt and the split conveyor belt. The second pushing component pushes the shower curtain towards its middle part, folding it and pushing it between the transition conveyor belt and the split conveyor belt. Then it is conveyed again along the split conveyor belt. A fixing frame is fixedly connected in the equipment box located above the split conveyor belt, and a fixing device is installed on it. The shower curtain is equipped with positioning sensors, such as infrared sensors and cameras, to detect and locate its position. A third pushing component is fixedly connected to the fixing frame. When the longitudinally folded shower curtain reaches above the guiding component, the third pushing component pushes the middle of the shower curtain laterally, allowing it to enter the guiding component and achieve a lateral folding operation. A mounting plate is fixedly connected to the discharge box located on one side of the guiding roller and the discharge conveyor belt. A fourth pushing component is fixedly connected to one side of the mounting plate. The guiding component guides the laterally folded shower curtain downward to one side of the guiding roller. When the middle of the shower curtain is located on one side of the guiding roller and the discharge conveyor belt, the fourth pushing component pushes the middle of the shower curtain, allowing it to enter between the guiding roller and the discharge conveyor belt, performing a second lateral folding operation on the shower curtain. After that, it is conveyed along the discharge conveyor belt to the discharge port, and finally, it is manually bagged or bagged by a subsequent packaging machine.

Different pushing methods are adapted for different folding stages, flexibly responding to changes in shower curtain size and improving equipment versatility and ease of operation.

[0028] 4. The guide roller and the discharge conveyor belt integrate a guiding component, directly conveying the finished product to the discharge port after the second lateral fold, shortening the transmission path. Combined with a third motor drive, it ensures continuous output of folded finished products, seamlessly connecting manual or mechanical packaging processes and optimizing the overall production flow.

[0029] 5. The equipment utilizes multi-level conveyor belt transmission (such as feeding, transition, and split conveyor belts) and synchronous gears to achieve efficient power transmission and reduce energy consumption. The layout of each component is reasonable, and support legs and reinforcing plates enhance overall stability, making it suitable for long-term continuous operation. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0044] Please see Figure 1-12A shower curtain folding and packaging device includes an equipment box 1, a feeding conveyor belt, a transition conveyor belt, a split conveyor belt, a guiding assembly 14, a guiding roller 4, and a discharging conveyor belt. Several support legs 11 are fixedly connected to the bottom of the equipment box 1. A reinforcing plate 12 is fixedly connected to the lower end of a support plate 2, and a support rod 13 is fixedly connected to the middle of the reinforcing plate 12 for supporting the overall installation of the device. A feeding conveyor belt is fixedly installed inside the equipment box 1 to transport the unfolded shower curtain into the equipment box 1 for folding. One end of the feeding conveyor belt extends out of the equipment box 1, and both sides are fixedly installed on the support plate 2. One end of each support plate 2 is fixedly connected to the outer wall of the equipment box 1. A transition conveyor belt is fixedly installed inside the equipment box 1 below the feeding conveyor belt to achieve the second... In the relative conveying of a folded shower curtain, one end of the transition conveyor belt is close to one end of the feeding conveyor belt, and the other end of the transition conveyor belt is close to the split conveyor belt. The split conveyor belt is fixedly installed in the equipment box 1 below the transition conveyor belt and is used to convey the shower curtain that is folded again. The split conveyor belt is equipped with a guide component 14 to facilitate the horizontal folding operation of the shower curtain. Both ends of the guide component 14 are fixedly connected to the inner wall of the equipment box 1. The bottom of the equipment box 1 below the guide component 14 is fixedly connected to the discharge box 3. One end of the discharge box 3 extends out of the equipment box 1 and is provided with a discharge port. The discharge box 3 is rotatably connected to the guide roller 4. The discharge conveyor belt is fixedly installed in the discharge box 3 below the guide roller 4. After being folded horizontally again, the shower curtain is discharged and then packaged.A first pushing component 5 is fixedly installed in the equipment box 1 located on one side of the feeding conveyor belt and the transition conveyor belt. When the shower curtain exits the feeding conveyor belt and its middle part is located between the feeding conveyor belt and the transition conveyor belt, the first pushing component 5 folds the shower curtain longitudinally and pushes the folded part between the feeding conveyor belt and the transition conveyor belt, thereby folding the shower curtain and conveying it along the transition conveyor belt. A second pushing component 6 is fixedly installed in the equipment box 1 located on one side of the transition conveyor belt and the split conveyor belt. After the shower curtain is folded longitudinally for the first time, it exits the transition conveyor belt and its middle part is located between the transition conveyor belt and the split conveyor belt. The second pushing component 6 pushes the shower curtain towards its middle part, folding and pushing the shower curtain between the transition conveyor belt and the split conveyor belt, and then conveys it again along the split conveyor belt. A fixing frame 7 is fixedly connected in the equipment box 1 located above the split conveyor belt, and a positioning sensor is installed on the fixing frame. Devices such as infrared sensors and cameras are used to detect and position the shower curtain. A third pushing component 8 is fixedly connected to the fixing frame 7.

A mounting plate 9 is fixedly connected to the discharge box 3 located on one side of the guiding roller 4 and the discharge conveyor belt. A fourth pushing component 10 is fixedly connected to one side of the mounting plate 9. The guiding component 14 guides the laterally folded shower curtain downward to one side of the guiding roller 4. When the middle of the shower curtain is located on one side of the guiding roller 4 and the discharge conveyor belt, the fourth pushing component 10 pushes the middle of the shower curtain, causing it to enter between the guiding roller 4 and the discharge conveyor belt, performing a second lateral folding operation on the shower curtain. After that, it is conveyed along the discharge conveyor belt to the discharge port, and finally manually bagged or bagged by a subsequent packaging machine.

The first material belt roller 101 and the second material belt roller 102 can relatively convey the first guide belt 103, so that the shower curtain can be relatively conveyed through the first guide belt 103. In this process, the second material belt roller 102 drives the first gear 105 to rotate relatively through the second gear 106. The first gear 105 drives the first pressure roller 104 to rotate. The first pressure roller 104 can ensure that the shower curtain falls from one side of the transition conveyor belt, which facilitates the longitudinal folding of the shower curtain.

The shaft of the fourth material belt roller 202 passes through the equipment box 1 and is fixedly connected to a fourth gear 208. The fourth gear 208 and the third gear 207 mesh with each other. The third material belt roller 201 and the fourth material belt roller 202 are used to tension the second guide belt 204 and to drive the folded shower curtain. The fourth material belt roller 202 drives the fourth gear 208 to rotate through the third gear 207. The fourth gear 208 drives the second pressure roller 205 to rotate. The second pressure roller 205 ensures that the shower curtain hangs down from the other side of the second guide belt 204, which facilitates the longitudinal folding of the shower curtain again.

For the power transmission source, the first motor 305 can directly drive the sixth guide roller 302 to rotate. The sixth guide roller 302 directly drives the two sets of third guide belts 303. The third guide belts 303 drive the fifth guide roller 301 at the other end to rotate. The fifth guide roller 301 drives the fourth guide roller 202 to rotate through the second synchronous gear 304. The fourth guide roller 202 drives the second guide belt 204 to rotate. The second guide belt 204 drives the third guide roller 201 on the other side to rotate.

In addition, the seventh material belt roller 401 drives the fifth gear 404 at the other end to rotate. The fifth gear 404 drives the meshing sixth gear 405 to rotate. The sixth gear 405 drives the guide roller 4 to rotate. The guide roller 4 cooperates with the shower curtain to fold and convey it to the discharge conveyor belt.

[0049] Please see Figure 9The material guiding assembly 14 includes a crossbeam frame 501, an elastic telescopic rod 502, a sliding guide block 503, a feeding roller 504, a translation plate 505, a second motor 506, a drive sprocket 507, a transmission sprocket 508, and a third synchronous gear 509. Two sets of symmetrical crossbeam frames 501 are arranged inside the third material guiding belt 303. Both ends of the crossbeam frames 501 are fixedly connected to the inner wall of the equipment box 1. Sliding guide grooves are provided on opposite sides of each crossbeam frame 501. Two sets of symmetrical sliding guide blocks 503 are slidably connected to each other. A feeding roller 504 is rotatably connected between the sliding guide blocks 503. A transmission sprocket 508 is provided at one end of each feeding roller 504. One set of transmission sprockets 508 is connected to a drive sprocket 507 via a chain belt. The drive sprocket 507 is fixedly connected to the shaft of a second motor 506. The second motor 506 is fixedly connected to a translation plate 505. Both ends of the translation plate 505 are fixedly connected to the corresponding sliding guide blocks 504. On one side of the sliding guide block 503, an elastic telescopic rod 502 is fixedly connected to one of the opposite ends of the sliding guide block 503. The other end of the elastic telescopic rod 502 is fixedly connected to the crossbeam frame 501. The other end of the feeding roller 504 is provided with a third synchronous gear 509, and the two sets of third synchronous gears 509 are meshed with each other. When the shower curtain is conveyed to the top of the feeding roller 504 by the third guide belt 303, the third pushing component 8 pushes the shower curtain downward along the guide gap to the middle of the shower curtain between the two sets of feeding rollers 504. Then, the second motor 506 drives the drive sprocket 507 to rotate. The drive sprocket 507 drives the transmission sprocket 508 to rotate through the chain belt. The transmission sprocket 508 drives the feeding roller 504 on the adjacent side to rotate. The other end of the feeding roller 504 drives the feeding roller 504 to rotate synchronously through the third synchronous gear 509. Thus, through the relative rotation of the feeding roller 504, the shower curtain is conveyed downward into the discharge box 3.

[0050] Please see Figure 10 and Figure 11 The first pushing assembly 5 and the second pushing assembly 6 have the same configuration, both including a first sliding guide rail 601, a first sliding block 602, a first pushing plate 603, a first pushing cylinder 604, a sliding sleeve 605, and a sliding rod 606. The first sliding block 602 is fixedly connected to both ends of the first pushing plate 603, and the first sliding block 602 is slidably connected to the first sliding guide rail 601. The first sliding guide rail 601 is fixedly connected to the inner wall of the equipment box 1. The first pushing cylinder 604 is fixedly connected to the middle of the first pushing plate 603. A sliding guide rod is fixedly connected to the first push plate 603 on both sides of the push cylinder 604. The other end of the sliding guide rod is connected to the sliding sleeve tube. The sliding sleeve tube and the first push cylinder 604 are both fixedly connected to the inner wall of the equipment box 1 on the opposite side. In use, the first push cylinder 604 is used to push out or retract the first push plate 603. The first sliding guide rail 601 and the first sliding block 602 located on both sides are used to achieve the stability of the first push plate 603 when it moves. The shower curtain is folded relative to each other through the first push plate 603.

[0051] Please see Figure 12 The third pushing assembly 8 includes a chute frame 701, a second pushing plate 702, a chute rail 703, a chute block 704, a connecting rod 705, a two-way lead screw 706, a guide block 707, a guide rail 708, and a fourth motor 709. The chute frame 701 is fixedly connected to a fixed frame 7 directly above the material guide gap. The second pushing plate 702 is movably connected inside the chute frame 701. Guide blocks 707 are fixedly connected to both ends of the second pushing plate 702. The guide blocks 707 are slidably connected to the guide rail 708, which is fixedly connected to both sides inside the chute frame 701. Two sets of symmetrical connecting rods 705 are hinged to the upper middle part of the second pushing plate 702. The other ends of the connecting rods 705 are hinged to the chute blocks 704. The chute blocks 704 are slidably connected inside the chute rail 703. A bidirectional lead screw 706 is rotatably connected inside the slide rail 703 and fixedly connected to the upper end of the slide frame 701. All slide blocks 704 are threadedly connected to the bidirectional lead screw 706. One end of the bidirectional lead screw 706 passes through the slide rail 703 and is connected to the fourth motor 709. The fourth motor 709 is fixedly connected to one side of the slide frame 701. In use, the fourth motor 709 can drive the bidirectional lead screw 706 to rotate. The bidirectional lead screw 706 drives the slide blocks 704 to move towards or away from each other through two opposite threads. When moving towards each other, it drives one end of the connecting rod 705 to move closer to each other. Through the relative flipping of the connecting rod 705, the second pusher plate 702 is pushed downward out of the slide frame 701. Finally, the second pusher plate 702 pushes the shower curtain into the guide gap between the two sets of third guide belts 303, and then pushes it between the two sets of discharge rollers 504.

[0052] Please see Figure 7 and Figure 8 The fourth pushing assembly 10 includes a second sliding guide rail 801, a second sliding block 802, a third pushing plate 803, and a second pushing cylinder 804. The second sliding blocks 802 are fixedly connected to both sides of the third pushing plate 803, and each second sliding block 802 is slidably connected to the second sliding guide rail 801. The second sliding guide rail 801 is fixedly connected to the inner wall of the discharge box 3. The second pushing cylinder 804 is fixedly connected to the middle of the third pushing plate 803, and the other end of the second pushing cylinder 804 is fixedly connected to the mounting plate. On 9, similar to the working principle of the first pushing component 5 and the second pushing component 6, in specific operation, the second pushing cylinder 804 directly pushes the third pushing plate 803 to move between the guide roller 4 and the discharge conveyor belt. The second sliding guide rail 801 and the second sliding block 802 located at both ends of the third pushing plate 803 further improve the relative stability of the third pushing plate 803 when it moves, thereby folding the shower curtain led out by the discharge roller 504 and pushing it to the discharge conveyor belt to convey the folded shower curtain outward.

[0053] Please see Figure 1-12In the specific operation of this invention, firstly, in the split conveyor belt, the first motor 305 is fixedly connected to the outer wall of the equipment box 1 and can drive the sixth material belt roller 302 inside the equipment box 1 to rotate. The sixth material belt roller 302 drives the third guide belt 303 to rotate, the third guide belt 303 drives the fifth material belt roller 301 to rotate, the fifth material belt roller 301 drives the fourth material belt roller 202 to rotate through the second synchronous gear 304, the fourth material belt roller 202 drives the second guide belt 204 to rotate, the second guide belt 204 drives the third material belt roller 201 to rotate, the third material belt roller 201 drives the first guide belt 103 to rotate through the first synchronous gear 206, and the first guide belt 103 drives the first material belt roller 101 between the support plates 2 to rotate. At this time, the shower curtain is flat. The shower curtain is laid out on the first guide belt 103 between the support plates 2. The first guide belt 103 conveys the shower curtain to one side of the second guide roller 102 and guides it out, causing one end of the shower curtain to droop to one side of the third guide roller 201. The first baffle plate 203 prevents the drooping shower curtain from rolling onto the second guide belt 204. When the middle of the shower curtain droops to one side of the first pusher assembly 5, the first pusher cylinder 604 is activated. The first pusher cylinder 604 pushes the first pusher plate 603 to move into the gap between the second and third guide rollers 201, thereby folding the middle of the shower curtain and conveying it between the second and third guide rollers 102 and 201. At this time, through the relative transmission of the first guide belt 103 and the second guide belt 204, the shower curtain is guided into the first guide belt 204. The shower curtain is fed between the material belt 103 and the second guide belt 204. After being introduced, the folded shower curtain is conveyed along the second guide belt 204, exiting from one end of the fourth material belt roller 202. The folded shower curtain then hangs down to one side of the fifth material belt roller 301. The second baffle plate 306 on one side of the fifth material belt roller 301 is also used to place the shower curtain as it is wound onto the third guide belt 303. Then, when the middle part of the folded shower curtain hangs down to one side of the second pusher assembly 6, the first pusher cylinder 604 is activated, causing the first pusher plate 603 on one side of it to push the middle part of the shower curtain to the gap between the fourth material belt roller 202 and the fifth material belt roller 301. The shower curtain is then wound up by the relatively driven second guide belt 204 and third guide belt 303. The shower curtain falls onto the third guide belt 303 and is conveyed along it. When the shower curtain reaches directly above the guide assembly 14, the third push assembly 8 activates the fourth motor 709. The fourth motor 709 drives the bidirectional lead screw 706 to rotate. The bidirectional lead screw 706 drives the sliding blocks 704 to move towards each other through threads. The sliding blocks 704 drive the connecting rod 705 to perform relative flipping motion. The connecting rod 705 pushes the second push plate 702 downward. The second push plate 702 pushes the middle part of the shower curtain from the guide gap between the third guide belts 303 to between the two sets of discharge rollers 504. The two sets of discharge rollers 504 convey the folded shower curtain downward to the guide roller 4 and the discharge conveyor belt side. When the middle part of the shower curtain falls to one side of the fourth push assembly 10...In the fourth feeding assembly 10, the second feeding cylinder 804 is activated. The second feeding cylinder 804 pushes the third feeding plate 803 towards the center of the shower curtain, pushing the center of the shower curtain into the gap between the guide roller 4 and the seventh material belt roller 401. Then, the shower curtain is guided towards the outlet direction by the guide roller 4 and the third guide belt 303 until it is transported to the discharge port by the third guide belt 303, facilitating subsequent bagging.
