[0002] A duvet cover, also known as a "quilt cover," is placed over a quilt to prevent it from getting dirty and to make it easier to wash. It belongs to the category of bedding products. There are now many automated machines for duvet covers or bed sheets that can automatically produce them.

[0003] Currently, existing production equipment for duvet covers or bed sheets often leaves a significant amount of fabric remaining after producing a certain size or pattern. Because these fabrics are not the right size, they cannot be processed on the existing equipment, resulting in a considerable waste of raw materials.

[0056] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0057] This invention provides a semi-automatic duvet cover machine to solve the problem that in the prior art, after the production equipment for bed sheet products has produced a certain size or pattern of fabric, there is still a lot of fabric left over. Because the size is not suitable, the fabric cannot be processed on the existing production equipment, resulting in serious waste.

[0058] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figure 1 A semi-automatic duvet cover making machine according to an embodiment of this application includes a feeding module 1, a transmission module 2, a labeling mechanism 3, a belt attaching device 4, a side sewing machine 5, a turning transmission module 6, a third-side sewing machine 7, and a take-up module 8. The feeding module 1 is used to transmit fabric forward at an inclined slope. The transmission module 2 is configured to dock with the feeding module 1 to transmit the fabric delivered by the feeding module 1. The labeling mechanism 3 is arranged along one side of the transmission module 2 to deliver a label to the fabric. Two belt attaching devices 4 are arranged vertically along both sides of the transmission module 2 and located at the rear end of the labeling mechanism 3 to deliver belts to the four corners of the fabric. Two side sewing machines 5 are respectively arranged vertically along the transmission module 2 and located at the rear end of the corresponding belt attaching device 4 to sew the two sides of the fabric together with the label.

[0059] The turning and conveying module 6 is distributed along the vertical direction of the conveying module 2 to turn the fabric sent out by the conveying module 90° before conveying it; the third-side sewing machine 7 is set along one side of the turning and conveying module 6 to sew the third side of the fabric; the receiving module 8 is set along the vertical direction of the turning and conveying module 6 to turn the sewn fabric backward for receiving.

[0060] The semi-automatic duvet cover machine of the present invention uses an inclined slope to transport the fabric, and then sequentially completes the labeling of the fabric, the feeding of the drawstrings at the four corners of the fabric, the sewing of the two sides of the fabric, and then turns the fabric 90° to sew the other side, thereby automatically completing the sewing of three sides of the fabric to produce a duvet cover with drawstrings at the four corners. It has high production efficiency and meets actual processing needs.

[0061] based on Figures 2 to 7In this embodiment, the feeding module 1 includes two feeding devices 10 arranged opposite to each other. Each feeding device 10 has an upwardly inclined feeding surface. A feeding synchronous belt is provided on the feeding surface of the feeding device 10 to transport the folded fabric forward. A clamping assembly 100 is provided along the running direction of the feeding synchronous belt to press the fabric. The fabric is folded manually, and then the clamping assembly 100 clamps the folded fabric, which is then transported upward by the feeding synchronous belt to the subsequent transmission device 2.

[0062] The transmission module 2 includes two transmission devices 20 arranged opposite to each other, and the two feeding devices 10 and the two transmission devices 20 are arranged one in front of the other and one behind each other to form a combined transmission module for the two oppositely arranged devices to cooperate in the transmission of fabric; the feeding devices 10 and the transmission devices 20 on any one of the combined transmission modules are arranged laterally on two corresponding first sliding rails 11 and two second sliding rails 12 through a transmission mechanism, respectively. The two first sliding rails 11 are arranged opposite to each other below the feeding devices, and the two second sliding rails 12 are arranged opposite to each other below the transmission devices 20.

[0063] Specifically, the transmission mechanism includes a transmission shaft 13 that passes through the feeding device 10 and the transmission device 20. The transmission shaft 13 is driven by a transmission motor 14. Synchronous transmission wheels 15 located on the transmission shaft 13 are respectively provided above the two first sliding rails 11 and the two second sliding rails 12.

[0064] Each of the first sliding rails 11 and the upper surfaces of each of the second sliding rails 12 are provided with sliding groups located below the feeding device 10 and the conveying device 20. The sliding groups include two oppositely arranged rollers 16. The two rollers 16 are connected to the synchronous transmission wheel 15 by a synchronous belt. In this way, the synchronous transmission wheel 15 drives the two rollers 16 to rotate synchronously on the first sliding rail 11 and the second sliding rail 12 and then move laterally, thereby driving the entire left side of the feeding device and the conveying device to move laterally synchronously.

[0065] To make the lateral movement of the feeding device and the conveying device more precise, a moving component is provided on both sides of the pulley group of each first sliding rail 11 and the first sliding rail 12, located below the feeding device and the conveying device. The moving component includes a moving pulley 17 and an auxiliary pulley 18. The moving pulley slides directly in contact with the ground, while the auxiliary pulley 18 can be guided to slide on the first sliding rail 11 and the second sliding rail 12.

[0066] During operation, when the positions of the feeding module and the conveying module need to be adjusted according to the size of the fabric, the drive motor 14 first starts working. The rotation of the drive motor 14 drives the drive shaft 13 to drive the transmission. When the drive shaft 13 rotates, it drives the four synchronous transmission wheels 15 to rotate synchronously. Each pair of synchronous transmission wheels 15 is respectively set at the first sliding rail 11 and the second sliding rail 12. The synchronous transmission wheels 15 drive the feeding device and the conveying device to move laterally on the first sliding rail 11 and the second sliding rail, respectively, through two rollers 16. At this time, the auxiliary rollers 19 can move in a guiding manner on the first sliding rail 11 and the second sliding rail 12, thereby playing a guiding role. In addition, the moving pulleys are in direct contact with the ground, so the feeding device and the conveying device can be quickly and effectively moved laterally to the left and right sides by moving the moving pulleys, thereby adjusting the distance between the two combined conveying modules to adapt to different fabric processing needs.

[0067] In this embodiment, the labeling mechanism 3 is a label delivery mechanism that can deliver two labels. This structure is a common technology and will not be described here.

[0068] based on Figure 9 The transmission device 20 includes a transmission support 202, on which an upper transmission synchronous belt 200 and a lower transmission synchronous belt 201 are arranged in parallel. The upper transmission synchronous belt 200 and the lower transmission synchronous belt 201 are used to drive the fabric forward along the length direction of the two transmission supports 202.

[0069] based on Figures 8 to 11 In this embodiment, the upper belt device 4 includes an upper belt seat 40, a discharge assembly, a clamping assembly 44, a shearing assembly 45, a folding assembly 46, a pressing assembly, and an opening assembly 47. The discharge assembly includes a discharge tray 41 for placing the rope on the upper belt seat 40. Above the discharge tray 41 are driven rollers 48 and two parallel discharge auxiliary rollers 42. Below the discharge auxiliary rollers 42 is a discharge plate 43 with slots for vertical passage of the rope. During operation, the rope is fed out from the discharge tray 41, then passes through the driven rollers 48 and the two discharge auxiliary rollers 42 in sequence, and then enters the slots of the discharge plate 43 for limiting and continuing to be transported downward.

[0070] The clamping assembly 44 is movably disposed below the slot to pull the rope moving downward from the slot downward, thereby pulling out the rope of an appropriate length. The clamping assembly 44 consists of two clamping jaws that can clamp each other, driven by a cylinder. The shearing assembly 45 is disposed between the discharge plate 43 and the clamping assembly 44 to cut the rope of a fixed length. In this embodiment, the shearing assembly 45 includes a cutter 451 that can move laterally via a transverse cylinder 450, and the cutter 451 cuts off the rope of a fixed length.

[0071] The folding assembly 46 is located below the shearing assembly 45. In this embodiment, the folding assembly 46 includes a sliding plate 462 that can move laterally on the slide rail 461 via a folding cylinder 460. The sliding plate is provided with an L-shaped folding plate 463. During operation, the folding plate 463 moves forward under the drive of the folding cylinder 460. After the folding plate 463 moves forward, it folds the rope onto the fabric between the upper transmission synchronous belt 200 and the lower transmission synchronous belt 201.

[0072] An opening assembly 47 is disposed between the folding assembly 46 and the shearing assembly 45. The opening assembly 47 includes a first pressing cylinder 470 inclined to the lower left corner, and a second pressing cylinder 471 inclined to the lower right corner in the vertical direction of the first pressing cylinder 470. The bottom of the second pressing cylinder 471 is provided with a U-shaped inclined insert plate 472. In actual operation, after the rope is folded in half, it is sent to the upper transmission synchronous belt 200 and the lower transmission synchronous belt 202 of the transmission bracket 202. When the fabric between the upper and lower transmission synchronous belts 201 needs to be increased, the first pressing cylinder 470 drives the second pressing cylinder 471 to tilt to the left. Then, the second pressing cylinder 471 drives the insert plate 472 to move downward, so that the insert plate 472 is inserted between the upper and lower transmission synchronous belts 200 and 201 to increase the gap. Then, the folding plate 463 folds the folded rope into the gap between the two.

[0073] The pressing assembly is located in front of the opening assembly 4 and is used to press the cord inserted into the fabric to facilitate subsequent cutting of the cord. In this embodiment, the pressing assembly includes a pressing plate 480 that can move up and down.

[0074] The actual workflow is as follows:

[0075] 1. The rope is fed out by the discharge plate 41, then transferred to the two discharge auxiliary rollers 42, and then fed to the slot limit in the discharge plate 43 before being sent downward;

[0076] 2. Next, the clamping assembly 44 clamps the front end of the rope, and then the clamping assembly 44 drags the rope down to a certain distance and then stops it at a fixed length;

[0077] 3. After the insert plate 472 inside the opening assembly 47 moves forward, the gap between the upper transmission synchronous belt 200 and the lower transmission synchronous belt 201 will increase;

[0078] 4. The folding cylinder in the folding assembly pushes forward, and the folding plate 463 folds the rope onto the fabric between the upper transmission synchronous belt 200 and the lower transmission synchronous belt 201.

[0079] 5. After the clamping plate 480 moves down, it clamps the rope. Then the cutting component 45 cuts off the upper end of the rope. Then the opening component and the folding component return to their original positions, thus realizing the automatic rope feeding operation.

[0080] On the other side of the fabric, the upper belt device 4 feeds the ropes. After the fabric is transported to one end, the upper belt devices 4 on both sides feed the ropes on both sides of the fabric, so that there are ropes at all four corners of the duvet cover. The ropes support the duvet cover and ensure the quality of the product.

[0081] based on Figure 8 and Figure 12 When the transmission module 2 transmits the fabric, if the fabric is not accelerated to be sent to the steering transmission module 6, the overall transmission efficiency of the fabric will be low because the transmission module 2 cannot quickly send the fabric to the steering transmission module 6, which in turn leads to low production efficiency. Therefore, a fabric speed-increasing mechanism is added between the end of the transmission module 2 and the steering transmission module 6 to accelerate the transmission of the fabric.

[0082] In this embodiment, the fabric speed-increasing mechanism 9 is located at the end of the transmission module 6. The fabric speed-increasing mechanism includes a speed-increasing bracket 90, an active roller 91, an auxiliary roller 93, and an auxiliary synchronous belt 94. Two oppositely arranged active rollers 91 are rotatably mounted on the speed-increasing bracket 90 and driven by a motor 92. Two oppositely arranged auxiliary rollers 93 are located below each of the active rollers. The two auxiliary synchronous belts 94 are driven to rotate by a corresponding active roller and two auxiliary rollers, respectively.

[0083] When the fabric is conveyed to the fabric speed-increasing mechanism 9, the motor 92 starts to work. The motor 92 drives the auxiliary roller 93 forward through the active roller 91 and the auxiliary synchronous belt 94. Thus, the motor 92 drives the fabric to the turning and conveying module 6. In this way, the fabric conveying speed is independently controlled by the motor 92, so the fabric conveying can be accelerated, and the fabric can be transferred from one direction to another as quickly as possible, which improves the turning and conveying efficiency of the fabric and thus improves the processing efficiency of the entire duvet cover.

[0084] In this embodiment, the steering transmission module 6 includes a steering support 60, on which a first transmission belt 61 and a second transmission belt 62 are arranged vertically and parallel to each other, and the opposite ends of the first and second transmission belts extend outwards with corresponding extension sections; above the first transmission belt 61 and the second transmission belt 62, there are respectively a first pressing mechanism 63 and a second pressing mechanism 64 that can move laterally for pressing the fabric on the first transmission belt 61 and the second transmission belt 62, wherein the first pressing mechanism 63 and the second pressing mechanism 64 are common open components.

[0085] During operation, the first pressing mechanism 63 presses the fabric onto the first conveyor belt 61, which drives the fabric to move laterally to the right. When the fabric reaches the side where the first conveyor belt 61 and the second conveyor belt 62 are parallel to each other, the first pressing mechanism 63 releases the fabric. Then, the second pressing mechanism 64 presses the fabric onto the second conveyor belt 62, which then drives the fabric to continue moving to the right to the extension of the second conveyor belt 62. This achieves the turning and subsequent transport of the fabric. In this duvet cover machine, the fabric is transported by the cooperation of the first conveyor belt 61 and the second conveyor belt 62. This prevents the fabric from being misaligned or wrinkled during transport, thus improving the yield rate of the fabric.

[0086] In addition, the turning and transmission module 6 is used to turn the fabric and transmit it to the right. The third-side sewing machine is installed on the side of the turning and transmission module 6 closest to the transmission module. This position is set as the right-hand position of the turning and transmission module 6. This is because this position is the forward sewing position of the third sewing machine. If the third-side sewing machine is placed on the other side of the turning and transmission module, i.e. the left-hand position, the fabric needs to be turned over before sewing, which will increase production costs and space requirements, and reduce processing efficiency.

[0087] In this embodiment, the material collection module 8 is a device that uses a fabric clamp to pick up the fabric from the turning and conveying module 6, and then rotates it 90° to collect the fabric.

[0088] The overall processing flow of the quilting machine of this invention is as follows:

[0089] S1. Synchronously adjust the distance between the two feeding devices and the two conveying devices to adapt to the size of the fabric;

[0090] S2. Manually place the folded fabric onto the feeding device and use the clamping assembly to clamp the folded fabric. Then the feeding device drives the folded fabric upward to the conveying device, and then the clamping assembly releases the fabric.

[0091] S3. When the folded fabric is transferred at the transfer module, the labeling mechanism first loads two labels onto the fabric.

[0092] S4. The upper belt mechanism on both sides of the transmission module performs upper belt operation on the four corners of the folded fabric to ensure that the finished pillowcase can be supported.

[0093] S5. Then, the two sides of the fabric are sewn together by a side sewing machine to attach the label and drawstring to the fabric.

[0094] S6. The fabric sewn on both sides is quickly sent to the turning and transmission module by the auxiliary speed-increasing device. The turning and transmission module turns the fabric 90° and then continues to transmit it.

[0095] S7. In the process of sending the fabric to the receiving module, the third-side sewing machine sews the third side of the fabric, and finally the receiving module collects the pillowcase made of the fabric after the three sides are sewn together.

[0096] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
