Description
Technical Field
[0001] The present invention relates to the technical field of punching of weakly adhesive films, and in particular to a punching processing device for a weakly adhesive self-adhesive film. Background Art

[0004] After the existing weakly adhesive auxiliary materials are punched, it is necessary to tear off the punched auxiliary materials. Since the surface of the auxiliary materials is thin at the joints after punching, and the auxiliary materials are on the surface of the self-adhesive film and have a certain viscosity on the surface, when pulling the auxiliary materials, due to the long distance, the problem of breakage of the auxiliary materials will occur during the pulling process. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a weak-adhesion self-adhesive film punching and processing device, which includes a processing table and a support frame fixedly installed on the outer surface of the processing table.

A heater is fixedly installed on the outer surface of the one-way air-permeable partition. An air extraction pump one is fixedly installed on the outer surface of the one-way air-permeable partition and at one edge position of the heater.
[0007] In an embodiment of the present invention, a main conveying material cylinder, a lower sticky winding cylinder and an upper sticky winding cylinder are respectively arranged at one end of the support frame, and the outer surface of the weak-adhesion self-adhesive film is movably sleeved on the outer surface of the main conveying material cylinder.
[0008] In an embodiment of the present invention, sticky auxiliary material layers are respectively movably sleeved on the outer surfaces of the lower sticky winding cylinder and the upper sticky winding cylinder, and the outer surfaces of the sticky auxiliary material layers are movably attached to the upper and lower surfaces of the weak-adhesion self-adhesive film.
[0009] In an embodiment of the present invention, an extrusion roller is arranged on the inner wall surface of the processing table, and the outer surface of the extrusion roller is movably sleeved on the outer surface of the sticky auxiliary material layer.
[0010] In an embodiment of the present invention, an air extraction pump two is fixedly installed on the outer surface of the cooling roller, a plurality of condensing pipes are fixedly installed on the inner wall surface of the cooling roller, and a fine air-permeable net two is arranged on the outer surface of the cooling roller.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:
[0017] For a weakly adhesive self-adhesive film punching and processing device of the present invention, when the weakly adhesive self-adhesive film continuously moves inside the processing table, the outer surface of the weakly adhesive self-adhesive film is wrapped by cooperating with the hot pressing roller and the cooling roller. At this time, the heater on the inner side wall surface of the hot pressing roller is used for high-temperature heating inside the hot pressing roller, so that hot air accumulates inside the hot pressing roller. At this time, the air extraction pump 1 is used to extract the hot air generated by the heater, so that the hot air flows back and forth inside the hot pressing roller through the one-way air permeable partition. At this time, the heat source will be conducted out through the hot pressing roller, so that the surface of the hot pressing roller is always in a high-temperature state. At this time, the weakly adhesive self-adhesive film will adhere to the surface of the hot pressing roller, and the high-temperature heat source will gradually relax the viscosity between the weakly adhesive self-adhesive film and the adhesive auxiliary material layer, and the waste material recovery roller will pull down the excess adhesive auxiliary material layer and wind up the excess adhesive auxiliary material layer;
[0018] For a weakly adhesive self-adhesive film punching and processing device of the present invention, the anti-slip soft pads on the outer side surfaces of the hot pressing roller and the cooling roller are used to increase the friction force with the adhesive auxiliary material layer, so that the adhesive auxiliary material layer can be preferentially pulled down from the surface of the weakly adhesive self-adhesive film. Furthermore, when the waste material recovery roller pulls the adhesive auxiliary material layer, due to the too long length of the adhesive auxiliary material layer and the too large viscosity between the adhesive auxiliary material layer and the weakly adhesive self-adhesive film, the surface of the adhesive auxiliary material layer will be deformed, bent or even broken during the pulling process. After the adhesive auxiliary material layer is broken, the adhesive auxiliary material layer will move along with the movement of the weakly adhesive self-adhesive film, and the excess adhesive auxiliary material layer on the surface of the weakly adhesive self-adhesive film cannot be pulled and torn off. The effect is achieved that the hot pressing roller and the cooling roller preferentially tear the adhesive auxiliary material layer from the surface of the weakly adhesive self-adhesive film, reduce the subsequent pulling and dragging force of the adhesive auxiliary material layer, and can easily recycle the adhesive auxiliary material layer.

Detailed implementation manners
[0028] The following further explains the present invention in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments given are not intended to limit the present invention.
[0029] Please refer to Figure 1 - Figure 7, the present invention provides a weak - adhesion self - film punching and processing device, including a processing table 11 and a support frame 13 fixedly installed on the outer surface of the processing table 11, a weak - adhesion self - film 12 movably sleeved on the outer surface of the support frame 13 and located on the inner wall surface of the processing table 11, a lapping table 14 fixedly installed at one - side edge position of the processing table 11. On the inner wall surface of the lapping table 14, a hot - pressing roller 141 and a cooling roller 149 are respectively arranged, and the outer surfaces of the hot - pressing roller 141 and the cooling roller 149 are movably sleeved on the outer surface of the weak - adhesion self - film 12. Anti - slip soft pads 148 are arranged on the outer surfaces of the hot - pressing roller 141 and the cooling roller 149. Fine breathable nets one 147 are respectively arranged on the outer surface of the hot - pressing roller 141. A support rod 143 is fixedly installed on the inner wall surface of the hot - pressing roller 141. One - way breathable partitions 144 are respectively fixedly installed on the outer surface of the support rod 143 and at both - side edge positions of the hot - pressing roller 141. A heater 145 is fixedly installed on the outer surface of the one - way breathable partition 144. An air - extraction pump one 146 is fixedly installed on the outer surface of the one - way breathable partition 144 and at one - side edge position of the heater 145;
[0030] As the weak - adhesion self - film 12 continuously moves inside the processing table 11, the outer surface of the weak - adhesion self - film 12 is wrapped by the cooperation of the hot - pressing roller 141 and the cooling roller 149. At this time, with the heater 145 on the inner wall surface of the hot - pressing roller 141 heating at a high temperature inside the hot - pressing roller 141, hot air accumulates inside the hot - pressing roller 141. At this time, with the cooperation of the air - extraction pump one 146, the hot air generated by the heater 145 is extracted, so that the hot air flows back and forth inside the hot - pressing roller 141 through the one - way breathable partition 144. At this time, the heat source is conducted out through the hot - pressing roller 141, making the surface of the hot - pressing roller 141 always in a high - temperature state. At this time, the weak - adhesion self - film 12 will adhere to the surface of the hot - pressing roller 141. The high - temperature heat source will gradually relax the viscosity between the weak - adhesion self - film 12 and the adhesive auxiliary layer 135, and make the waste - material recovery roller 113 pull down the excess adhesive auxiliary layer 135 and wind up the excess adhesive auxiliary layer 135;
[0031] The surface of the viscous auxiliary material layer 135 is extruded by the hot pressing roller 141 and the cooling roller 149. Since the distances between the hot pressing roller 141 and the cooling roller 149 and the weakly adhesive self - carrying film 12 are the closest, while the hot pressing roller 141 and the cooling roller 149 rotate alternately, the viscous auxiliary material layer 135 is adhered to the outer surface of the hot pressing roller 141. At the same time, the anti - slip soft pads 148 on the outer surfaces of the hot pressing roller 141 and the cooling roller 149 are used to increase the friction force with the viscous auxiliary material layer 135. Thus, the viscous auxiliary material layer 135 can be preferentially pulled off from the surface of the weakly adhesive self - carrying film 12. Furthermore, when the waste material recovery roller 113 pulls the viscous auxiliary material layer 135, due to the excessive length of the viscous auxiliary material layer 135 and the too large adhesion between the viscous auxiliary material layer 135 and the weakly adhesive self - carrying film 12, the surface of the viscous auxiliary material layer 135 will be deformed, bent or even broken during the pulling process. After the viscous auxiliary material layer 135 breaks, the viscous auxiliary material layer 135 will move along with the movement of the weakly adhesive self - carrying film 12, and the excess viscous auxiliary material layer 135 on the surface of the weakly adhesive self - carrying film 12 cannot be pulled and torn off. It achieves the effect of preferentially tearing off the viscous auxiliary material layer 135 from the surface of the weakly adhesive self - carrying film 12 by the hot pressing roller 141 and the cooling roller 149, reducing the subsequent pulling and dragging force of the viscous auxiliary material layer 135, and easily recycling the viscous auxiliary material layer 135.
[0032] Furthermore, as Figure 1 - Figure 2 and Figure 4 shown, a main conveying material cylinder 131, a lower viscous winding cylinder 132 and an upper viscous winding cylinder 133 are respectively arranged at one end of the support frame 13. The outer surface of the weakly adhesive self - carrying film 12 is movably sleeved on the outer surface of the main conveying material cylinder 131. The viscous auxiliary material layer 135 is movably sleeved on the outer surfaces of the lower viscous winding cylinder 132 and the upper viscous winding cylinder 133 respectively. The outer surface of the viscous auxiliary material layer 135 is movably attached to the upper and lower surfaces of the weakly adhesive self - carrying film 12. An extrusion roller 134 is arranged on the inner wall surface of the processing table 11, and the outer surface of the extrusion roller 134 is movably sleeved on the outer surface of the viscous auxiliary material layer 135.
[0033] Transport the weakly sticky self - adhesive film 12 in cooperation with the main conveying barrel 131. At the same time, cooperate with the upper sticky winding barrel 133 and the lower sticky winding barrel 132 on the outer surfaces of the two groups of support frames 13 to simultaneously attach the sticky auxiliary material layer 135 on their surfaces to the upper and lower surfaces of the weakly sticky self - adhesive film 12. At this time, then extrude the outer side of the sticky auxiliary material layer 135 through the extrusion roller 134. Meanwhile, on the premise that the weakly sticky self - adhesive film 12 is tightened, the surface of the weakly sticky self - adhesive film 12 can be in a flat and tightened state. Then, through the extrusion roller 134, the sticky auxiliary material layer 135 is tightly extruded and attached to the outer surface of the weakly sticky self - adhesive film 12, which can greatly reduce the effect that air bubbles will remain at the joint between the sticky auxiliary material layer 135 and the weakly sticky self - adhesive film 12. At the same time, under the extrusion of the extrusion roller 134, the sticky auxiliary material layer 135 can firmly adhere to the outer surface of the weakly sticky self - adhesive film 12.
[0034] Further, as Figure 1 - Figure 2 and Figure 5 shown, the outer surface of the sticky auxiliary material layer 135 is movably sleeved on the outer surface of the waste recycling roller 113, the outer surface of the anti - slip soft pad 148 is movably attached to the outer surface of the sticky auxiliary material layer 135, a support backing plate 111 is fixedly installed on the inner wall surface of the processing table 11, the top surface of the support backing plate 111 is movably lapped on the bottom surface of the weakly sticky self - adhesive film 12, a punching machine 112 is fixedly installed on the inner wall surface of the support backing plate 111, and the bottom surface of the punching machine 112 is movably lapped on the top surface of the weakly sticky self - adhesive film 12.
[0035] As the weakly sticky self - adhesive film 12 moves on the inner wall surface of the processing table 11, cooperate with the punching machine 112 to extrude the surface of the weakly sticky self - adhesive film 12, and then limit the downward pressure of the punching machine 112 through the support backing plate 111. At this time, the weakly sticky self - adhesive film 12 on the top surface of the support backing plate 111 is punched by the punching machine 112. At this time, utilize the sticky auxiliary material layer 135 on the outer surface of the punched - off weakly sticky self - adhesive film 12 to adhere to the surface of the punching auxiliary material recycling cylinder 114, and then cooperate with the punching auxiliary material recycling cylinder 114 to preliminarily recycle the waste punched off by the punching machine 112, without the need for employees to separately recycle the waste punched off by the punching machine 112 later.
[0036] Further, as Figure 3 - Figure 4 and Figure 7As shown, an air extraction pump II a3 is fixedly installed on the outer surface of the cooling roller 149, a plurality of condensing tubes a2 are fixedly installed on the inner wall surface of the cooling roller 149, a fine air-permeable net II a1 is arranged on the outer surface of the cooling roller 149, a punching auxiliary material recovery cylinder 114 is fixedly installed on the outer surface of the processing table 11 and at the middle position, a waste material recovery roller 113 is fixedly installed on the top surface of the overlapping table 14, motors 142 are fixedly installed on the inner wall surfaces on both sides of the overlapping table 14, and the output ends of the motors 142 are respectively fixedly installed on the outer surfaces on both sides of the hot pressing roller 141 and the cooling roller 149.
[0037] The excess hot air will accumulate and fill in the middle position of the hot pressing roller 141. As the hot air continuously accumulates and expands, some heat sources will penetrate through the fine air-permeable net I 147 and then come into contact with the surface of the weak self-adhesive film 12. As the heat sources continuously contact the surface of the weak self-adhesive film 12, the heat sources will approximately soften the adhesion between the viscous auxiliary material layer 135 and the weak self-adhesive film 12, thus facilitating the effect that when the hot pressing roller 141 and the cooling roller 149 pull the viscous auxiliary material layer 135 later, the viscous auxiliary material layer 135 can be torn off from the surface of the weak self-adhesive film 12 more quickly.
[0038] When the cooling roller 149 pulls the viscous auxiliary material layer 135, it cools itself in cooperation with the condensing tubes a2. At this time, the air extraction pump II a3 is used to absorb the external air into the interior of the cooling roller 149. At this time, the air blown by the air extraction pump II a3 comes into contact with the surface of the condensing tubes a2, and then mixes with the cold air on the surface of the condensing tubes a2. As the cold air continuously expands inside the cooling roller 149, the excess cold air will quickly cool the surface of the cooling roller 149. The excess cold air will penetrate through the fine air-permeable net I 147 and then quickly cool the surface of the viscous auxiliary material layer 135, thereby solidifying the overheated viscous auxiliary material layer 135, reducing the adhesion of the viscous auxiliary material layer 135, and facilitating the effect that the waste material recovery roller 113 can recover the viscous auxiliary material layer 135 later.
[0039] Working principle: It cooperates with the main conveying barrel 131 to transport the weakly adhesive self - carrying film 12. At the same time, it cooperates with the upper adhesive winding barrel 133 and the lower adhesive winding barrel 132 on the outer surface of the two groups of support frames 13 to simultaneously attach the adhesive auxiliary layer 135 on their surfaces to the upper and lower surfaces of the weakly adhesive self - carrying film 12. At this time, the outer side of the adhesive auxiliary layer 135 is extruded by the extrusion roller 134. Meanwhile, on the premise that the weakly adhesive self - carrying film 12 is tightened, the surface of the weakly adhesive self - carrying film 12 can be in a flat and tightened state. Then, the adhesive auxiliary layer 135 is tightly extruded and attached to the outer surface of the weakly adhesive self - carrying film 12 by the extrusion roller 134, which can greatly reduce the effect that air bubbles will remain at the joint between the adhesive auxiliary layer 135 and the weakly adhesive self - carrying film 12. At the same time, under the extrusion of the extrusion roller 134, the adhesive auxiliary layer 135 can firmly adhere to the outer surface of the weakly adhesive self - carrying film 12;
[0040] As the weakly adhesive self - carrying film 12 moves on the inner wall surface of the processing table 11, it cooperates with the punching machine 112 to extrude the surface of the weakly adhesive self - carrying film 12. Then, the position of the downward pressure of the punching machine 112 is limited by the support backing plate 111. At this time, the weakly adhesive self - carrying film 12 on the top surface of the support backing plate 111 is punched by the punching machine 112. At this time, the adhesive auxiliary layer 135 on the outer surface of the punched - out weakly adhesive self - carrying film 12 adheres to the surface of the punching auxiliary material recovery cylinder 114, and then cooperates with the punching auxiliary material recovery cylinder 114 to preliminarily recover the waste materials punched by the punching machine 112, eliminating the need for employees to separately recover the waste materials punched by the punching machine 112 later;
[0041] As the weakly adhesive self - carrying film 12 continuously moves inside the processing table 11, it cooperates with the hot - pressing roller 141 and the cooling roller 149 to wrap the outer surface of the weakly adhesive self - carrying film 12. At this time, the heater 145 on the inner wall surface of the hot - pressing roller 141 conducts high - temperature heating inside the hot - pressing roller 141, causing hot air to accumulate inside the hot - pressing roller 141. At this time, the air - extraction pump 146 extracts the hot air generated by the heater 145, causing the hot air to flow back and forth inside the hot - pressing roller 141 through the one - way breathable partition 144. At this time, the heat source is conducted out through the hot - pressing roller 141, keeping the surface of the hot - pressing roller 141 at a high - temperature state. At this time, the weakly adhesive self - carrying film 12 adheres to the surface of the hot - pressing roller 141. The high - temperature heat source causes the viscosity between the weakly adhesive self - carrying film 12 and the adhesive auxiliary layer 135 to gradually relax, and the waste material recovery roller 113 pulls down the excess adhesive auxiliary layer 135 and winds up the excess adhesive auxiliary layer 135;
[0042] The surface of the adhesive auxiliary layer 135 is extruded by the hot pressing roller 141 and the cooling roller 149. Since the distances between the hot pressing roller 141 and the cooling roller 149 and the weakly adhesive self-adhesive film 12 are the closest, when the hot pressing roller 141 and the cooling roller 149 rotate alternately, the adhesive auxiliary layer 135 is attached to the outer surface of the hot pressing roller 141. At the same time, the anti-slip soft pads 148 on the outer surfaces of the hot pressing roller 141 and the cooling roller 149 are used to increase the friction force with the adhesive auxiliary layer 135, so that the adhesive auxiliary layer 135 can be preferentially pulled off from the surface of the weakly adhesive self-adhesive film 12. Furthermore, when the waste material recovery roller 113 pulls the adhesive auxiliary layer 135, due to the too long length of the adhesive auxiliary layer 135 and the too large adhesion between the adhesive auxiliary layer 135 and the weakly adhesive self-adhesive film 12, the surface of the adhesive auxiliary layer 135 will be deformed, bent or even broken during the pulling process. After the adhesive auxiliary layer 135 is broken, the adhesive auxiliary layer 135 will move together with the movement of the weakly adhesive self-adhesive film 12, and the redundant adhesive auxiliary layer 135 on the surface of the weakly adhesive self-adhesive film 12 cannot be pulled and torn off. The effect is achieved that the hot pressing roller 141 and the cooling roller 149 preferentially tear the adhesive auxiliary layer 135 from the surface of the weakly adhesive self-adhesive film 12, reduce the subsequent pulling and dragging force of the adhesive auxiliary layer 135, and can easily recycle the adhesive auxiliary layer 135;
[0043] The redundant hot air accumulates and fills in the middle position of the hot pressing roller 141. As the hot air continuously accumulates and expands, some heat sources penetrate through the fine air-permeable net 147 and then come into contact with the surface of the weakly adhesive self-adhesive film 12. When the heat sources continuously contact the surface of the weakly adhesive self-adhesive film 12, the heat sources will approximately soften the adhesion between the adhesive auxiliary layer 135 and the weakly adhesive self-adhesive film 12, so as to facilitate the effect that when the hot pressing roller 141 and the cooling roller 149 pull the adhesive auxiliary layer 135 later, the adhesive auxiliary layer 135 can be torn off from the surface of the weakly adhesive self-adhesive film 12 more quickly;
[0044] While the cooling roller 149 cools itself while pulling the viscous auxiliary material layer 135, at this time, the second air extraction pump a3 is used to absorb the outside air into the inside of the cooling roller 149. At this time, the air blown by the second air extraction pump a3 comes into contact with the surface of the condensing pipe a2, and then mixes with the cold air on the surface of the condensing pipe a2. As the cold air continuously expands inside the cooling roller 149, the excess cold air will quickly cool the surface of the cooling roller 149. The excess cold air will penetrate out through the fine breathable net 147, thereby quickly cooling the surface of the viscous auxiliary material layer 135, and then solidifying the overheated viscous auxiliary material layer 135, so as to reduce the viscosity of the viscous auxiliary material layer 135, which is convenient for the later waste recycling roller 113 to recycle the viscous auxiliary material layer 135.
[0045] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
