DETAILED DESCRIPTION

[0024] The embodiment of the utility model provides a clamping cutter 3110 device, and the application will be further described below with reference to the accompanying drawings.

[0025] At the same time, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] Please refer to the attached Figures 1 to 4 The clamping cutter 3110 device includes a first lower conveying unit 10, a cutter assembly 30 and a second lower conveying unit 20 which are arranged in sequence.

[0027] Among them, the first lower conveying unit 10 includes a first supporting conveyor belt 11 wound on a plurality of rollers, and the first supporting conveyor belt 11 includes a first supporting conveying surface 111, which is used to support the product through the first supporting conveyor belt 11 and transport it to the cutter assembly 30 arranged downstream. The product can be a continuous sheet product, such as a semi-finished product of a sanitary napkin, a diaper, a mattress, or a breast pad. In another embodiment, the product can also be the core of a sanitary napkin, a diaper, a mattress, or a breast pad. Of course, it can also be other products that need to be cut.

[0028] It is understandable that the cutter assembly 30 may also be an embossing roller assembly for forming indentations on the product surface, which will not be described in detail herein.

[0029] In this embodiment, the first lower conveying unit 10 also includes a negative pressure device arranged on the lower side of the first supporting conveying surface 111, which is used to form a negative pressure on the first supporting conveying surface 111, so that the product remains attached to the first supporting conveying surface 111 during the conveying process, thereby preventing unexpected displacement.

[0030] The second lower conveying unit 20 is arranged downstream of the cutter assembly 30, and includes a second supporting conveyor belt 21 wound around a plurality of rollers. The second supporting conveyor belt 21 includes a second supporting conveying surface 211, which is used to convey the cut products to the downstream direction through the second supporting conveying surface 211.

[0031] It can be understood that the second supporting and conveying surface 211 is flush with the first supporting and conveying surface 111 .

[0032] The cutter assembly 30 includes a cutter roller 31 and a bottom roller 32, wherein the cutter roller 31 includes a cutter portion 311, and a cutter 3110 for cutting the product is provided in the cutter portion 311. In the present embodiment, the cutter portion 311 is provided in the middle of the cutter roller 31, and connecting portions 312 are provided on both sides of the cutter portion 311. At the same time, the cutter roller 31 includes an end portion located outside the connecting portion 312, and the end portion is rotatably provided on the cutter 3110 frame.

[0033] It can be understood that the cutter assembly 30 also includes a transmission device for driving the cutter roller 31 and the bottom roller 32 to rotate. The transmission device can be a gear, a synchronous belt, etc., which will not be described in detail here.

[0034] It can be understood that when the cutter roller 31 rotates, the end of the cutter 3110 moves along a first track 3111 , and the first track 3111 contacts the surface of the bottom roller 32 so that the product is cut during the rotation of the cutter 3110 .

[0035] Meanwhile, the connecting portion 312 has an outer diameter smaller than the first track 3111 , and a first gap 3121 is formed between the connecting portion 312 and the bottom roller 32 for at least a portion of the first clamping conveyor belt 41 to pass through.

[0036] The clamping and cutting knife device also includes an upper conveying unit 40, and the upper conveying unit 40 includes a first clamping conveying belt 41, and the first clamping conveying belt 41 includes a first clamping conveying surface 411, and the first clamping conveying surface 411 includes a first clamping section 4111 arranged opposite to the first supporting conveying surface 111 and forming a first clamping area, and a second clamping section 4112 passing through the cutter assembly 30 and arranged opposite to the second supporting conveying surface 211 to form a second clamping area.

[0037] It can be understood that after passing through the first gap 3121 , the second clamping section 4112 extends toward the second supporting conveyor belt 21 and forms a second clamping area with the second supporting conveyor surface 211 .

[0038] In this embodiment, the upper conveying unit 40 includes a driving roller 43, a front guide roller assembly 44 including a first front guide roller 441, and a first rear guide roller 45, wherein the first front guide roller 441 is located on the upper side of the first supporting conveying surface 111, and the first rear guide roller 45 is located on the upper side of the second supporting conveying surface 211. The first clamping conveyor belt 41 is wound around the driving roller 43, the first front guide roller 441, and the first rear guide roller 45. It can be understood that the first clamping conveying surface 411 is the side of the first clamping conveyor belt 41 facing the first supporting conveying surface 111 and the second supporting conveying surface 211. At the same time, a portion of the first clamping conveying surface 411 is in contact with the first clamping conveying surface 411. A supporting conveying surface 111 forms a first clamping area, and after passing through the first gap 3121, the part opposite to the second supporting conveying surface 211 forms a second clamping area with the second supporting conveying surface 211, that is, the part forming the first clamping area with the first supporting conveying surface 111 is the first clamping section 4111, and the part forming the second clamping area with the second supporting conveying surface 211 is the second clamping section 4112. It can be understood that through the above-mentioned arrangement, the product is still in a clamping state and a conveying state when being acted on by the cutter assembly 30, so that the product can continue to move, avoiding the situation in the prior art that the product cannot enter the second supporting conveying surface 211 and cause blockage.

[0039] Furthermore, there is a pair of first clamping conveyor belts 41, which are respectively arranged on both sides of the cutting knife part 311, so as to be able to clamp and convey the product from both sides.

[0040] Furthermore, the upper conveying unit 40 also includes a second clamping conveyor belt 42 and a second rear guide roller 46, the front guide roller assembly 44 includes a second front guide roller 442, the second clamping conveyor belt 42 is wound around the second rear guide roller 46, the second front guide roller 442 and the driving roller 43, and at the same time, the second rear guide roller 46 is arranged upstream of the cutting roller 31, and the second clamping conveyor belt 42 forms a second clamping conveying surface 421 between the second front guide roller 442 and the second rear guide roller 46, and a third clamping area is formed between the second clamping conveying surface 421 and the first supporting conveying surface 111, that is, the product upstream of the cutting knife assembly 30 will be clamped and conveyed by the first clamping area and the third clamping area, further improving the stability of product conveying and the stability when the cutter 3110 cuts the product.

[0041] At the same time, it can be understood that the second clamping conveyor belt 42 and the first clamping conveyor belt 41 are both driven by the driving roller 43 so that the two move synchronously.

[0042] Furthermore, the first rear guide roller 45 and the second rear guide roller 46 have the same outer diameter.

[0043] Furthermore, the first clamping area, the second clamping area, and the third clamping area have the same clamping height, where the clamping height refers to the distance between two opposite clamping surfaces, so that the product is under the same clamping force.

[0044] It is understandable that in some cases, the height on both sides of the product is smaller than the height in the middle, and the clamping height of the first clamping zone and the second clamping zone can be set to be smaller than the clamping height of the third clamping zone, so that the product can remain clamped by the first clamping zone, the second clamping zone and the third clamping zone.

[0045] Furthermore, the second clamping conveyor belt 42 is arranged corresponding to the cutter portion 311 , so that after being conveyed through the second clamping area, the product enters the area corresponding to the cutter portion 311 and the bottom roller 32 and is cut by the cutter 3110 .

[0046] Furthermore, a middle guide roller 47 is provided between the second rear guide roller 46 and the driving roller 43, and the middle guide roller 47 includes a lower endpoint 471, and the lower endpoint 471 is the point where the distance between the middle guide roller 47 and the first supporting conveying surface 111 is the smallest. At the same time, a second gap 472 is included between the lower endpoint 471 and the first clamping conveying surface 411, and the width of the second gap 472 is smaller than the outer diameter of the second rear guide roller 46, so that the first supporting conveying belt 11 is overlapped on the second rear guide roller 46, so that the first clamping conveying belt 41 and the second clamping conveying belt 42 always maintain synchronous movement. At the same time, by providing the middle guide roller 47, the first clamping conveying belt 41 and the second clamping conveying belt 42 have a larger wrap angle on the driving roller 43, so that the driving roller 43 can drive the first clamping conveying belt 41 and the second clamping conveying belt 42 at the same time.

[0047] For further information, please refer to Figure 5 The first front guide roller 441 and the second front guide roller 442 are independently arranged, so that the rotation of the first front guide roller 441 and the rotation of the second front guide roller 442 will not affect each other. In the present embodiment, the first front guide roller 441 and the second front guide roller 442 are both arranged on a cross bar 443, one end of the cross bar 443 is fixed on the frame 50, and the other end extends in the direction away from the frame 50. The arrangement of the second front guide roller 442 is specifically described below, and the arrangement of the first front guide roller 441 is not repeated.

[0048] Specifically, a main bracket 444 is also provided on the cross bar 443. The main bracket 444 is in a "mouth" shape, including a bottom plate, side plates extending from both sides of the bottom plate, and a top plate connecting the pair of side plates and closing the space surrounded by the bottom plate and the side plates. The bottom plate is fixed to the cross bar 443 by fixing bolts 445. At the same time, a pair of support plates 446 are also provided on the main bracket 444. Each support plate 446 is correspondingly arranged on a side plate and extends outward from the main bracket 444, so that the pair of support plates 446 are fork-shaped on the main bracket 444, and the second front guide roller 442 is arranged on the pair of support plates 446.

[0049] Furthermore, the support plate 446 also includes an adjusting device. Specifically, the adjusting device includes an adjusting hole 447 and an adjusting bolt 448 arranged on the support plate 446. The adjusting hole 447 has a length direction, and the adjusting bolt 448 includes a length direction parallel to the length direction of the adjusting hole 447. At the same time, the cross bar 443 includes a screw hole parallel to the length direction of the adjusting hole 447 and corresponding to the bottom of the support plate 446. The adjusting bolt 448 is inserted into the screw hole and its end contacts the bottom of the support plate 446. When the adjusting bolt 448 is rotated, the adjusting bolt 448 moves along its length direction so that the position of the support plate 446 changes along its length direction, and further changes the position of the second front guide roller 442 located at the end of the support plate 446, so as to further adjust the tension and position of the second clamping conveyor belt 42.
