Description

Technical Field

[0001] The invention relates to the technical field of sanitary product manufacturing, and in particular to a composite processing device for producing diapers. Background Art

[0002] During the production process of diapers, the materials of the elastic waist are transported longitudinally. After production is completed, the elastic waist needs to be turned horizontally to be combined with the main body of the diaper.

[0003] The patent document with the announcement number CN206261735U discloses a variable speed device for a diaper production line, which absorbs the elastic waistband through the adsorption unit. When the adsorption unit is in the longitudinal position, the strip elastic waistband is adsorbed. As the moving seat moves, each adsorption unit performs a speed-up movement within a period of time after resetting, and the interval between adjacent adsorption units in the longitudinal position gradually increases, the strip elastic waistband adsorbed on the adjacent adsorption units can be torn into sections of elastic waistband, and each adsorption unit adsorbs a section of elastic waistband. As the moving seat continues to move, the guide rod drives the crank arm and the driven shaft to rotate through the guide of the change-direction guide groove to realize the adsorption unit change direction and reset, and the adsorption unit can change direction and turn horizontally together with the elastic waistband; and each adsorption unit performs a speed-down movement within a period of time after the change of direction, which is conducive to transferring the elastic waistband on the adsorption unit to other mechanisms to combine with the diaper body.

[0039] like Figure 1 to Figure 2As shown, a composite processing device for diaper production provided by an embodiment of the present invention comprises a speed-changing and horizontal-changing device 100, wherein the speed-changing and horizontal-changing device 100 comprises a bracket 101, on which an eccentric cylinder 102 is fixedly provided, and the eccentric cylinder 102 is a cylinder; a main shaft 104 is provided for rotation inside the eccentric cylinder 102, and the main shaft 104 extends in a horizontal direction, and the axis of the main shaft 104 and the eccentric cylinder 102 do not coincide, and a limit assembly 103 is fixedly provided on the main shaft 104, and a plurality of suction cup assemblies 200 are provided on the limit assembly 103, and the rotation of the main shaft 104 drives the limit assembly 103 to rotate synchronously, and the limit assembly 103 drives the plurality of suction cup assemblies 200 to rotate around the main shaft 104 while sliding along the outer peripheral surface of the eccentric cylinder 102, so that the suction cup assembly 200 changes speed and changes horizontally.

[0040] like Figures 3 to 15 As shown, the suction cup assembly 200 includes a rotating shaft 202 and an air suction plate 206, and the air suction plate 206 is used for negative pressure adsorption of diaper non-woven fabrics; an arc-shaped support plate 205 is fixedly provided on the rotating shaft 202, and the air suction plate 206 is a rectangular plate; the suction cup assembly 200 in the initial position is longitudinal, and the length direction of the air suction plate 206 is perpendicular to the main axis 104, the axis of the arc-shaped support plate 205 is parallel to the main axis 104, and the width direction of the air suction plate 206 is parallel to the main axis 104. After the suction cup assembly 200 becomes horizontal, the length direction of the air suction plate 206 is parallel to the main axis 104, the width direction of the air suction plate 206 is perpendicular to the main axis 104, and the axis of the arc-shaped support plate 205 is parallel to the main axis 104. The shaft 104 is vertical; the arc-shaped support disc 205 is connected to the air suction plate 206, and the air suction plate 206 rotates around the axis of the arc-shaped support disc 205; a cutting mechanism 209 is provided at one end of the length direction of the air suction plate 206, a rotating cylinder 2021 is rotatably sleeved on the rotating shaft 202, a hydraulic driving mechanism is provided between the air suction plate 206 and the rotating cylinder 2021, and the hydraulic driving mechanism is connected to the cutting mechanism 209 in transmission; when two adjacent suction cup assemblies 200 pull the diaper non-woven fabric, the diaper non-woven fabric will cause the air suction plate 206 to rotate unidirectionally around the axis of the arc-shaped support disc 205, and then the hydraulic driving mechanism drives the cutting mechanism 209 to cut the diaper non-woven fabric. The speed change and transverse change of the suction cup assembly 200 belongs to the prior art, refer to the patent document CN206261735U. Specifically, a rotating ring 201 is provided at the bottom of the rotating shaft 202 , and an annular groove 1021 is provided on the eccentric cylinder 102 . The rotating ring 201 rotates around the annular groove 1021 to achieve speed and horizontal change of the suction cup assembly 200 .

[0041] In this way, when the suction cup assembly 200 pulls the diaper non-woven fabric, the diaper non-woven fabric will cause the suction plate 206 to rotate unidirectionally around the axis of the arc-shaped support plate 205, and then the hydraulic drive mechanism drives the cutting mechanism 209 to cut the diaper non-woven fabric. This direct way of cutting off the diaper non-woven fabric can avoid excessive pulling of the diaper non-woven fabric and cause inaccurate positioning of the diaper non-woven fabric.

[0042] In one embodiment, the arc-shaped support plate 205 is provided with a first suction port 2051, and the side of the air suction plate 206 facing the arc-shaped support plate 205 is provided with a second suction port 2061; after the air suction plate 206 rotates unidirectionally around the axis of the arc-shaped support plate 205, the overlapping area of ​​the first suction port 2051 and the second suction port 2061 increases. The first suction port 2051 and the second suction port 2061 are both circular, and two first suction ports 2051 are provided. In the length direction of the air suction plate 206, the cutting mechanism 209 is set to be located in front of the air suction plate 206, and the end where the cutting mechanism 209 is not provided is the rear. The two first suction ports 2051 are respectively located at the front and rear sides of the rotating shaft 202, and the two second suction ports 2061 correspond to the front and rear sides of the rotating shaft 202 respectively. In the initial state, the first suction port 2051 and the second suction port 2061 located in front of the rotating shaft 202 are staggered, and the first suction port 2051 and the second suction port 2061 located behind the rotating shaft 202 are staggered. After the suction plate 206 rotates unidirectionally around the axis of the arc-shaped support plate 205, the overlapping area of ​​the first suction port 2051 and the second suction port 2061 increases, so that the suction force of the suction plate 206 increases, the diaper non-woven fabric is not easily displaced, and the diaper non-woven fabric is prevented from being positioned inaccurately.

[0043] In one embodiment, the outer part of the rotating cylinder 2021 is provided with an air pump 204, the air pump 204 is connected to the arc-shaped support plate 205, and the side of the air suction plate 206 away from the arc-shaped support plate 205 is provided with a third suction port 2063, and the third suction port 2063 is used to contact the non-woven fabric of the diaper. A suction cavity 2062 is formed inside the air suction plate 206, and the suction cavity 2062 is respectively connected to the third suction port 2063 and the second suction port 2061, and a plurality of third suction ports 2063 are provided along the length direction of the air suction plate 206.

[0044] In one embodiment, an arc groove is provided at the bottom of the air-intake plate 206, and the chord length direction of the arc groove is consistent with the length direction of the air-intake plate 206. The arc support plate 205 extends into the arc groove and rotates with the arc groove; a sealing gasket 207 is provided on the arc support plate 205, and the air-intake plate 206 and the sealing gasket 207 are frictionally matched. The chord length direction of the arc support plate 205 is consistent with the length direction of the air-intake plate 206. Two sealing gaskets 207 are provided, which are respectively located at the front and rear ends of the arc support plate 205. The sealing gaskets 207 allow a certain gap between the arc support plate 205 and the air-intake plate 206, so that the air-intake plate 206 can rotate around the axis of the arc support plate 205.

[0045] In one embodiment, a limit plate 2052 is provided at one end of the arc-shaped support plate 205 away from the cutting mechanism 209, and the length direction of the limit plate 2052 is consistent with the length direction of the air suction plate 206. The limit plate 2052 can prevent the end of the air suction plate 206 away from the cutting mechanism 209 from rotating around the axis of the arc-shaped support plate 205. In this way, the air suction plate 206 can only rotate forward in one direction around the axis of the arc-shaped support plate 205.

[0046] In one embodiment, the side wall of the arc groove is provided with an arc-shaped limiting groove 2064, and the side of the arc-shaped support plate 205 is provided with a limiting block (not shown in the figure), and the limiting block is slidably matched with the arc-shaped limiting groove 2064. The connection between the arc-shaped support plate 205 and the air suction plate 206 is realized by the slidably matching between the limiting block and the arc-shaped limiting groove 2064, so as to prevent the two from being separated from each other.

[0047] In one embodiment, a rotating disk 203 is provided on the outside of the rotating cylinder 2021, and the hydraulic drive mechanism is a hydraulic telescopic rod 208; one end of the hydraulic telescopic rod 208 is hinged to the side of the suction plate 206 toward the arc-shaped support disk 205, and the other end is hinged to the rotating disk 203.

[0048] In one embodiment, a return spring 2081 is provided inside the hydraulic telescopic rod 208, and the return spring 2081 can restore the hydraulic telescopic rod 208 to its original length. When the hydraulic telescopic rod 208 restores its original length, the air suction plate 206 can be restored.

[0049] In one embodiment, two cutting mechanisms 209 are provided, and the two cutting mechanisms 209 are respectively located on both sides of the width direction of the suction plate 206. The cutting mechanism 209 includes a cutting cylinder 2092 and a cutter 2091. The length direction of the cutter 2091 is perpendicular to the length direction of the suction plate 206. The axis of the cutting cylinder 2092 is parallel to the length direction of the suction plate 206. The cutter 2091 can rotate around the axis of the cutting cylinder 2092. The cutting cylinder 2092 is connected to the hydraulic telescopic rod 208 through a hydraulic pipeline 210.

[0050] A first partition plate is fixedly provided inside the cutting barrel 2092, and a rotating shaft is provided at one end of the cutter 2091, which is coaxially arranged with the cutting barrel 2092, and the rotating shaft is connected with a second partition plate, which is rotatably located inside the cutting barrel 2092, and the second partition plate can rotate relative to the first partition plate, and the first partition plate and the second partition plate divide the cutting barrel 2092 into two chambers, one of which is connected to the hydraulic pipe 210. When the hydraulic telescopic rod 208 is retracted, the hydraulic oil in the hydraulic telescopic rod 208 enters each cutting barrel 2092 through the two hydraulic pipes 210, and pushes the second partition plate to rotate, so that the two cutters 2091 rotate around the axis of the cutting barrel 2092.

[0051] In one embodiment, the vacuum cylinder 204 is provided with a fourth suction port 2041 , and the fourth suction port 2041 is used to connect to a vacuum pump; the fourth suction port 2041 is provided with a regulating valve 2042 , and the regulating valve 2042 is used to adjust the size of the fourth suction port 2041 .

[0052] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0053] The speed change and transverse change device 100 is started to drive the multiple suction cup assemblies 200 to rotate around the outer peripheral surface of the eccentric cylinder 102. When the suction cup assemblies 200 approach each other and change longitudinally, the diaper non-woven fabric is adsorbed on the suction plate 206. As the suction cup assemblies 200 move away from each other and change transversely, the diaper non-woven fabric is pulled. The pulled diaper non-woven fabric will make the suction plates 206 on the two adjacent suction cup assemblies 200 tend to approach each other, so that the two adjacent suction plates 206 have a tendency to rotate around their respective arc-shaped support plates 205 toward the middle position of the two suction cup assemblies 200. Fig. 9 As shown, due to the presence of the limit plate 2052 behind the arc-shaped support plate 205, one of the air suction plates 206 cannot rotate backward around the arc-shaped support plate 205, so that only the other air suction plate 206 can rotate forward around the arc-shaped support plate 205. That is, only one of the two adjacent air suction plates 206 rotates.

[0054] The forward rotation of the suction plate 206 will squeeze the hydraulic telescopic rod 208 downward, causing the hydraulic telescopic rod 208 to shrink, and then the hydraulic oil in the hydraulic telescopic rod 208 enters the cutting cylinder 2092, driving the cutter 2091 to rotate. The cutter 2091 rotates to cut the diaper non-woven fabric to prevent the diaper non-woven fabric from being pulled off and causing inaccurate positioning. At the same time, the rotation of the suction plate 206 will increase the overlapping area between the first suction port 2051 and the second suction port 2061, thereby increasing the suction force of the suction plate 206, and the diaper non-woven fabric is less likely to shift during the cutting process. At the same time, during the rotation of the suction plate 206, the regulating valve 2042 can be controlled to increase the opening of the fourth suction port 2041 of the suction cylinder 204, further increasing the adsorption force when the diaper non-woven fabric is cut.

[0055] After the diaper non-woven fabric is cut, the two adjacent suction cup assemblies 200 gradually approach and become longitudinal, and the speed of the suction cup assembly 200 decreases. At the same time, because the diaper non-woven fabric no longer exerts pressure on the suction plate 206, under the action of the reset spring 2081, the hydraulic telescopic rod 208 gradually extends, so that the suction plate 206 gradually resets. Since the suction cup assembly 200 rotates around the eccentric cylinder 102 to generate centrifugal force, the centrifugal force of the suction cup assembly 200 can cause the suction plate 206 to rotate, thereby accelerating the reset of the suction plate 206, so that the suction plate 206 is more accurately positioned when it absorbs the diaper non-woven fabric again. This reciprocating process improves the production and processing quality of diapers.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
