Description

Technical Field

[0001] The utility model relates to a clamping and conveying device, in particular to a clamping and conveying device used for conveying disposable absorbent articles. Background Art

[0002] Disposable absorbent products, such as mattresses, sanitary napkins, and diapers, usually need to go through processes such as slitting, folding, and packaging. Among them, the folding process is to fold the disposable absorbent products in half or three to reduce the volume and facilitate packaging according to different specifications.

[0003] In the folding process, a folding knife is used in conjunction with a clamping and conveying device to perform folding during the clamping and conveying process. In the prior art, a conveyor belt with multiple rollers wrapped around the upper frame and the lower frame is usually used, wherein the belt of the lower frame is wrapped around to form a concave space, and the belt on the upper frame is wrapped around to form a circular structure extending into the above-mentioned concave space, and a slit is formed between the two for the disposable absorbent product to pass through. The folding knife is set at the corresponding position of the slit. When 1 / 3 or 1 / 2 of the disposable sanitary product is conveyed to this position, the folding knife moves to fold the disposable sanitary product by 1 / 3 or 1 / 2.

[0004] This structure has the following problems: the upper frame and the lower frame are respectively an integral structure, which is extremely bulky and inconvenient to install and disassemble; the position of the rollers constituting the upper frame and the lower frame is fixed, and the size of the slit cannot be adjusted. In particular, due to the obstruction of the lower frame, the position of the rollers on the lower frame is extremely difficult to adjust, and is not suitable for folding disposable sanitary products of different thicknesses; and the conveyor belt forms a concave space with dead corners, which makes the conveying process of disposable sanitary products extremely unsmooth, and the corner guide rollers at both ends of the bottom of the concave space of the lower frame are easily caught in the belt to be folded.

[0005] To this end, in an improved folding-clamping conveying device, specifically the device shown in CN212099639U, the conveying device is configured into at least two sets of independent conveying mechanisms, and the relative conveying surfaces of the two sets of conveying mechanisms form a smoothly transitioned U-shaped conveying channel through their respective roller assemblies. By setting up at least two sets of conveying mechanisms in the folding system, the conveying surfaces of the two sets of conveying mechanisms form a smoothly transitioned U-shaped conveying channel through their respective roller assemblies, and there are no dead corners, so that the objects to be folded can run smoothly in this U-shaped conveying channel, thereby improving the folding efficiency.

[0006] However, in further practice, it was found that the above device still had the following technical problems:

[0007] First, since the entire clamping and conveying process is long, products often get stuck unexpectedly during the conveying process. However, the existing technology, including the device shown in CN212099639U, makes it difficult to remove these stuck products, resulting in downtime losses.

[0008] Second, the conveyor belt used in the entire conveyor device needs to undergo multiple rotations. The existing conveyor device has a narrow adjustment range for the conveyor belt, making it difficult to remove the old conveyor belt and install a new conveyor belt when the conveyor belt needs to be reinstalled.

[0009] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0033] Please refer to Figures 1-6 An embodiment of the present invention provides a clamping and conveying device for conveying disposable absorbent products. The clamping and conveying device includes a frame and a plurality of conveying modules arranged on the frame.

[0034] Specifically, in this embodiment, it includes a first conveying module 11, a second conveying module 12, a third conveying module 13, a fourth conveying module 14, a fifth conveying module 15 and a sixth conveying module 16. The first conveying module 11, the second conveying module 12, the third conveying module 13, the fourth conveying module 14, the fifth conveying module 15 and the sixth conveying module 16 form a first conveying section 101, a second conveying section 102, a third conveying section 103, a fourth conveying section 104 and a fifth conveying section 105, which are arranged in sequence. The first conveying section 101 is located in the upstream direction, the fifth conveying section 105 is located in the downstream direction, and the second conveying section 102, the third conveying section 103 and the fourth conveying section 104 form a U-shaped conveying channel.

[0035] Furthermore, a first folding device is provided between the first conveying section 101 and the second conveying section 102 for folding the product passing through the first conveying section 101. The folding device includes a reciprocating folding knife. When a portion of the product extends out of the first conveying section 101, the folding knife applies an extrusion force to the product in a direction inclined to the base surface of the product, so that the product is folded while changing the direction of movement.

[0036] Furthermore, a second folding device is provided between the fourth conveying section 104 and the fifth conveying section 105 for performing a second folding on the product that has been folded once. It can be understood that the structure of the second folding device is basically the same as that of the first folding device. At the same time, the length of the product that has been folded twice is usually 1 / 3 of the length of the unfolded product. The second folding greatly reduces the length of the product, thereby facilitating packaging.

[0037] In this embodiment, the first conveying module 11 includes a first conveying belt 110 wound on a number of rollers. At the same time, the first conveying belt 110 includes a first pressing section 111. The second conveying module 12 is arranged below the first conveying module 11, including a second conveying belt 120 wound on a number of rollers. At the same time, the second conveying belt 120 includes a first supporting section 121. The first holding section 111 and the second supporting section 122 are arranged relative to each other to form a first clamping interval. It can be understood that the first clamping interval is the first conveying section 101. It can be understood that during the conveying process, the product will be clamped and conveyed by the first supporting section 121 and the first holding section 111.

[0038] At the same time, the third conveying module 13 includes a third conveying belt 130 wound on several rollers, the third conveying belt 130 includes a second pressing section 131, and the second conveying belt 120 also includes a second supporting section 122. The second supporting section 122 and the second pressing section 131 are arranged relative to each other to form a second clamping interval. The second clamping interval is the second conveying section 102. Since the second supporting section 122 and the first supporting section 121 are both part of the second conveying belt 120, the first conveying section 101 and the second conveying section 102 form a smooth transition, thereby facilitating the transfer of products from the first conveying section 101 to the second conveying section 102.

[0039] It can be understood that the second conveying section 102 is inclined with respect to the first conveying section 101 , and the angle between the second conveying section 102 and the first conveying section 101 is 110° to 140°.

[0040] In this embodiment, the frame is further provided with a first pressing mechanism 123 connected to the actuating device 1233 and movable to move the first supporting section 121 and the first pressing section 111 toward or away from each other.

[0041] In this embodiment, the first pressing mechanism 123 includes a pressing wheel 1231, a pressing bracket 1232 and an actuating device 1233. The pressing wheel 1231 is arranged on the pressing bracket 1232. The pressing bracket 1232 is connected to the actuating device 1233 and is configured to move toward or away from the first pressing section 111 under the drive of the actuating device 1233. When the actuating device 1233 drives the pressing bracket 1232 to move toward the first pressing section 111, the pressing wheel 1231 contacts the first supporting section 121 and causes the first supporting section 121 to move toward the first pressing section 111. When the actuating device 1233 drives the pressing bracket 1232 to move away from the first pressing section 111, the pressing wheel 1231 separates from the first supporting section 121, so that the first conveyor belt 110 is relaxed and the gap in the first clamping section is increased. When a product is stuck at this position, the product can be easily taken out from the first clamping section. Of course, the relaxed first conveyor belt 110 can also be easily removed from the roller and replaced with a new second conveyor belt 120.

[0042] Furthermore, there are at least two pressing wheels 1231. Specifically, the pressing bracket 1232 is T-shaped and includes a cross bar, and the pressing wheels 1231 are sequentially arranged on the cross bar.

[0043] Furthermore, the first conveying module 11 includes a first roller arranged opposite to the holding wheel 1231, and the first roller is fixedly arranged. The fixed arrangement means that the first roller is not connected to the actuating device 1233, so that its position with the first conveying belt 110 is fixed.

[0044] Furthermore, the frame is also provided with a second pressing mechanism 124 for bringing the second supporting section 122 and the second pressing section 131 closer to or apart from each other.

[0045] Furthermore, the first pressing mechanism 123 and the second pressing mechanism 124 are both arranged in the area enclosed by the second conveyor belt 120, so that the first pressing mechanism 123 and the second pressing mechanism 124 both apply pressure to the second conveyor belt 120 from the inside to the outside of the second conveyor belt 120, thereby adjusting the interval between the first pressing interval and the second pressing interval.

[0046] Furthermore, the second conveying module 12 also includes an adjustment mechanism 125, which includes an adjustment wheel 126 that can be moved from the outside to the inside to contact or move away from the second conveying belt 120, so as to adjust the tightness of the second conveying belt 120 from a larger range, thereby facilitating the removal of stuck products from the first clamping interval or the second clamping interval and replacing the second conveying belt 120.

[0047] Furthermore, the holding wheel 1231 is configured to be movably separated from the first conveyor belt 110, so that the interval between the first holding sections has a sufficient spacing distance, making it easy to remove the stuck product from the interval.

[0048] Furthermore, the third conveyor belt 130 includes a fourth pressing section 133, the sixth conveyor module 16 includes a sixth conveyor belt 160 wound on a number of rollers, the sixth conveyor belt 160 includes a fourth supporting section 161 arranged opposite to the fourth pressing section 133, the fourth pressing section 133 and the fourth supporting section 161 are arranged opposite to each other to form a fourth pressing interval, and the fourth pressing interval forms the fourth conveying section 104.

[0049] At the same time, the fifth conveying module 15 includes a fifth conveying belt 150 wound on several rollers, the fifth conveying belt 150 includes a fifth pressing section 151, and the sixth conveying belt 160 includes a fifth supporting section 162 arranged relative to the fifth pressing section 151. The fifth pressing section 151 and the fifth supporting section 162 form a fifth pressing interval, and the fifth pressing interval is the fifth conveying section 105.

[0050] The frame is further provided with a third pressing mechanism 163 and a fourth pressing mechanism 164 for respectively moving the fourth supporting section 161 and the fourth pressing section 133 closer to or away from each other, and moving the fifth supporting section 162 and the fifth pressing section 151 closer to or away from each other.

[0051] It can be understood that the structures of the second pressing mechanism 124 , the third pressing mechanism 163 and the fourth pressing mechanism 164 are substantially the same as that of the first pressing mechanism 123 .

[0052] The third conveyor belt 130 includes a third pressing section 132, the fourth conveying module 14 includes a swing frame 142, a plurality of rollers arranged on the swing frame 142 and a fourth conveyor belt 140 arranged around the plurality of rollers, the fourth conveyor belt 140 includes a third supporting section 141 arranged relative to the third pressing section 132, and at the same time, the swing frame 142 is configured to be rotatably arranged on the frame and rotate around the first axis under the drive of an actuating device 143, so that one end of the third supporting section 141 can move away from the third pressing section 132 or approach the third pressing section 132.

[0053] Furthermore, the fourth conveying module 14 includes a driving wheel for driving the fourth conveying belt 140 to move, and the first axis is the rotation axis of the driving wheel.

[0054] Furthermore, the swing frame 142 also includes a support 144 connected to the swing frame 142 , and a connecting rod 145 is included between the actuating device 1233 and the support 144 , and one end of the connecting rod 145 is pivotally connected to the support 144 .

[0055] Furthermore, the first conveying section 101 and the fifth conveying section 105 are symmetrically arranged, and the second conveying section 102 and the fourth conveying section 104 are symmetrically arranged.

[0056] The first conveying section 101 , the second conveying section 102 , the third conveying section 103 , the fourth conveying section 104 and the fifth conveying section 105 are all smoothly connected.

[0057] It is understandable that the actuating device may be a cylinder, a linear motor, an electromagnet, etc.
