Description

Technical Field

[0001] This invention belongs to the field of paper production technology, specifically relating to a dry-wet mixed absorbent paper production equipment. Background Technology

[0002] This invention relates to a production equipment for wet-dry mixed absorbent paper, belonging to the field of paper production technology. In existing technologies, the production of wet-dry mixed absorbent paper typically involves separately bonding a mixed paper base material and a dry paper base material to both sides of a release liner substrate. In traditional processes, these two base materials are often glued and pressed together in stages, which presents the following technical problems: Deformation of the base layer is easily caused during the gluing process: Since the mixed paper base material and the dry paper base material are pressed in stages, when pressure is applied to one side, the base layer of the release film is prone to wrinkles, collapse or displacement due to uneven force, which affects the quality of the finished product. Low production efficiency: The step-by-step gluing process leads to a longer production cycle, and the loading and unloading and gluing processes cannot be carried out synchronously, which restricts the overall production efficiency. Alignment accuracy is difficult to guarantee: Traditional equipment relies on manual or simple mechanical positioning when aligning multi-layer materials, which is prone to deviation and affects product consistency and yield.

[0003] Therefore, there is an urgent need for a dry-wet mixed absorbent paper production equipment that can achieve simultaneous double-sided pressing, improve alignment accuracy and production efficiency, in order to solve the above-mentioned technical problems. Summary of the Invention

A negative pressure loading arm assembly has an arm structure for negative pressure adsorption and support of the release liner substrate. In actual use, the dry paper base material on the second pressure suction cup and the mixed paper base material on the first pressure suction cup are synchronously pressed onto the adhesive layers on both sides of the release liner substrate. This method achieves synchronous adhesive pressing of the dry paper base material and the mixed paper base material.

[0038] In this embodiment, the two sets of synchronous counter-pressing feeding arm assemblies 200 are aligned on the same straight line on the second main shaft 107.

[0039] In a preferred embodiment, please refer to Figure 6The negative pressure loading arm assembly 300 includes a hollow U-shaped loading arm 301, a vent 302, an air pump 303, a loading arm shaft 304, and a loading arm end plate 305. The hollow U-shaped loading arm 301 has a vent 302 at its top, and a loading arm end plate 305 is fixedly installed at one end of the hollow U-shaped loading arm 301. The loading arm shaft 304 is fixedly installed at the bottom of the loading arm end plate 305, and the air pump 303 is installed near the bottom of the hollow U-shaped loading arm 301.

[0040] In this embodiment, the loading arm end plates 305 on the two sets of negative pressure loading arm assemblies 300 overlap and are simultaneously fixed on the first main shaft 113.

[0041] In this embodiment, the two sets of negative pressure loading arm assemblies 300 are aligned on the same straight line on the first main shaft 113.

[0042] The working principle of this invention is as follows: In the existing production of wet and dry mixed absorbent paper, the mixed paper base material 404 and the dry paper base material 403 need to be glued to the release film base layer 401 through the adhesive layer 402. However, when the mixed paper base material 404 and the dry paper base material 403 are glued separately, on the one hand, if the pressure is not properly controlled when the mixed paper base material 404 is pressed onto the release film base layer 401, it is very likely that the release film base layer 401 will be pressed off the stand or wrinkled. At the same time, the separate glued process of the mixed paper base material 404 and the dry paper base material 403 also increases the processing time of the glued process. In order to overcome the above problems, this invention simultaneously forms a material on the pressing and feeding arm assembly 200 for pressing the mixed paper base material... The structure allows for simultaneous adsorption and compression of material 404 and dry paper base material 403. The negative pressure loading arm assembly 300 forms an arm structure for negative pressure adsorption and support of the release liner base 401. Specifically, the first pair of pressure teeth arms 205 slides on one end of the square frame 201 via T-shaped sliders 206 and T-shaped slots 202, and the second pair of pressure teeth arms 212 slides on the other end of the square frame 201 via T-shaped sliders 206 and T-shaped slots 202. The first pair of pressure teeth arms 205 and the second pair of pressure teeth arms 212 are positioned on both sides of an auxiliary gear 207. One side of the auxiliary gear 207 meshes with the first pair of pressure teeth arms 205, and the other side meshes with the second pair of pressure teeth arms 212. The first pair of suction cups 209 and the second pair of suction cups 210 are positioned opposite each other. The bottom of the hydraulic cylinder 204 is fixed to the second pair of pressure arms 211. During the production of wet and dry mixed absorbent paper, the edge substrate of the release film base layer 401 is adsorbed onto the hollow U-shaped material carrier arm 301 through the vent hole 302. At this time, the mixed paper base material 404 is adsorbed onto the first pair of suction cups 209, and the dry paper base material 403 is adsorbed onto the second pair of suction cups 210. During gluing, the hydraulic cylinder 204 retracts, driving the second pair of pressure arms 211 to move upward. At this time, the second pair of pressure tooth arms 212, through meshing with the auxiliary gear 207, drives the first pair of pressure tooth arms 205 to move downward. In this way, the absorbent paper is produced. The first pair of suction cups 209 and the second pair of suction cups 210 simultaneously come into contact with each other at the top and bottom of the hollow U-shaped material carrier arm 301. In this way, the dry paper base material 403 on the second pair of suction cups 210 and the mixed paper base material 404 on the first pair of suction cups 209 are simultaneously pressed onto the adhesive layers 402 on both sides of the release film base layer 401. In this way, the dry paper base material 403 and the mixed paper base material 404 are simultaneously glued and pressed together. At the same time, during the simultaneous glued and pressed together, the top and bottom surfaces of the release film base layer 401 are subjected to a counterforce. Through this double-sided force, the release film base layer 401 will not be crushed or wrinkled during the glue process, thereby ensuring production quality.

[0043] It should be noted that the ends of the first pair of pressure arms 208 and the second pair of pressure arms 211 of the present invention may be provided with elastic telescopic rods, and the first pair of pressure suction cups 209 and the second pair of pressure suction cups 210 are disposed on the elastic telescopic rods. During pressure application, due to the provision of the elastic telescopic rods, even if the first pair of pressure tooth arms 205 and the second pair of pressure tooth arms 212 are excessively displaced, no pressure damage will occur between the first pair of pressure suction cups 209 and the second pair of pressure suction cups 210. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Based on the above, to facilitate the simultaneous loading and unloading of the base material and the pressing and bonding process, the double-headed robotic arm assembly 100 is equipped with two sets of synchronous pressing and loading arm assemblies 200 at one end, and two sets of negative pressure loading arm assemblies 300 at the other end. The two sets of synchronous pressing and loading arm assemblies 200 form a rotational fixed-point switching structure at one end of the double-headed robotic arm assembly 100, and the two sets of negative pressure loading arm assemblies 300 form a rotational fixed-point switching structure at the other end of the double-headed robotic arm assembly 100. The loading arm end platforms 305 on the two sets of negative pressure loading arm assemblies 300 overlap and are simultaneously fixed on the first main shaft 113. At this time, the two sets of negative pressure loading arm assemblies 300 are on the same straight line on the first main shaft 113, and the frame end platforms on the two sets of synchronous pressing and loading arm assemblies 200 are... 203 overlap and are simultaneously fixed on the second main shaft 107. At this time, the two sets of synchronous pressing and feeding arm assemblies 200 are on the same straight line on the second main shaft 107. That is, two sets of synchronous pressing and feeding arm assemblies 200 are provided on the second main shaft 107. When one set of synchronous pressing and feeding arm assemblies 200 is in the pressing and bonding stage, the other set of synchronous pressing and feeding arm assemblies 200 can perform feeding and unloading. At the same time, two sets of negative pressure loading arm assemblies 300 are provided on the first main shaft 113. When the isolation film base layer 401 is placed on one set of negative pressure loading arm assemblies 300 and rotated to the inside for pressing and bonding, the other set of negative pressure loading arm assemblies 300 can rotate to the outside for feeding and unloading. In this way, pressing and bonding and feeding and unloading are processed simultaneously and synchronously, saving processing time.

[0045] Based on the above, in order to ensure that the two sets of synchronous counter-pressure feeding arm assemblies 200 can rotate and be repositioned on the second main shaft 107, and in order to ensure that the two sets of negative pressure feeding arm assemblies 300 can rotate and be repositioned on the first main shaft 113, two sets of repositioning drive assemblies are provided at both ends of the dual-head robotic arm assembly 100. The repositioning drive assembly includes a positioning drive wheel 109, a positioning arc groove 110, a shifting groove 111, a partially driven wheel 108, a shifting arm 112, and a shifting rod 118. The positioning drive wheel 109 is provided with multiple positioning arc grooves 110 and multiple shifting grooves 111. A toggle arm 112 is fixedly installed at the bottom of the incomplete drive wheel 108, and a toggle lever 118 is fixedly installed at the distal end of the toggle arm 112. The positioning drive wheel 109 and the incomplete drive wheel 108 on one set of fixed-point shifting drive components are respectively fixed on the first main shaft 113 and the first branch shaft 115. The positioning drive wheel 109 and the incomplete drive wheel 108 on another set of fixed-point shifting drive components are respectively fixed on the second main shaft 107 and the second branch shaft 106. In actual use, the incomplete drive wheel 108 is driven to rotate by the first branch shaft 115 or the second branch shaft 106. Wheel 108 moves the positioning drive wheel 109 at a fixed angle via a lever 118 and a lever groove 111. This allows for the fixed-point rotation and repositioning of the two sets of synchronous pressing and feeding arm assemblies 200 and the two sets of negative pressure feeding arm assemblies 300, facilitating the vertical alignment of the mixed paper base material 404, the release film base layer 401, and the dry paper base material 403, thus facilitating subsequent pressing and gluing processes. Simultaneously, a second pulley 116 is fixedly mounted at the bottom of the first support shaft 115, and a first pulley 105 is fixedly mounted at the bottom of the second support shaft 106. The first pulley 105 and the second pulley... A belt 104 is fitted between the pulleys 116. In actual use, the drive motor 117 drives a set of fixed-point shifting drive components at one end of the dual-head robotic arm assembly 100 to rotate. At this time, through the cooperation of the second pulley 116, the belt 104 and the first pulley 105, a set of fixed-point shifting drive components at the other end of the dual-head robotic arm assembly 100 rotates synchronously. In this way, the synchronous shifting and fixed-point rotation of the two sets of synchronous pressing feeding arm assemblies 200 and the two sets of negative pressure feeding arm assemblies 300 are realized, which further facilitates the alignment and synchronous shifting of the subsequent multi-layer paper base material.
