Description

Technical Field

[0001] The invention belongs to the technical field of anesthesia packages, and in particular relates to an automatic forming device for folding strips. Background Art

[0002] Anesthesia kits are commonly used medical tools during surgery, and are often used to anesthetize the surgical site of the patient before surgery. Generally, anesthesia kits mainly include outer packaging and a storage box enclosed in the outer packaging, as well as anesthesia tools related to anesthesia work placed in the storage box, including air filters, disposable injection tools, sterile straight brushes, sterile hole towels, puncture needles, epidural catheters, catheter connectors, rubber medical gloves, medical gauze, and medical stickers. Among them, medical stickers are often used to fix puncture needles, or for other pasting operations during anesthesia; generally, two sizes of stickers need to be loaded into the anesthesia kit. The small sticker is smaller in size and can be used to fix needles, etc., and the large sticker is larger in size and is often used to wrap the patient's surgical site, etc.

[0003] In the prior art, the rolled stickers are first cut into large stickers and small stickers that meet the use requirements, and then loaded into the anesthesia bag. During the packaging process, due to the limited size of the anesthesia bag itself and its limited storage space, the overall size of the large sticker is larger than the size of the anesthesia bag packaging bag. Therefore, the large stickers often need to be folded before they can be completely loaded into the bag. In the current large sticker production process, the stickers are generally cut into large stickers one by one, and then the large stickers are folded by humans and then loaded into a storage box and then packaged into a packaging bag. In this way, the production of anesthesia bags requires a lot of manpower, high labor costs, and low work efficiency. Summary of the invention

[0070] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 16 The described embodiments are exemplary and intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0071] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0072] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0073] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0074] like Figures 1 to 16 As shown, an embodiment of the present invention provides an automatic forming device for a folding patch, which is applicable to but not limited to cutting a medical patch 101 into medical folding patches that can be packaged in an anesthesia bag. Specifically, Figure 1 As shown, the sticker 101 has a first side portion 1011 and a second side portion 1012 relative to each other along the width direction, and the first side portion 1011 and the second side portion 1012 are separated by a folding line 1013. When folding, the second side portion 1012 is folded along the folding line 1013 to overlap with the first side portion 1011. Moreover, the first side portion 1011 can be equal in width to the second side portion 1012, that is, the width of both is half of the overall width of the sticker 101. The first side portion 1011 and the second side portion 1012 can also have a difference in width, and when the two are equal in width, the overall width of the sticker 101 is the smallest after folding. When folding, the position of the folding line 1013 can be set according to the width requirement.

[0075] Furthermore, if Figure 2 and Figure 3As shown, the automatic forming device for folded strips includes a mounting frame 10, a feeding mechanism 20 mounted on the mounting frame 10, a folding mechanism 70 and a cutting mechanism 50. The mounting frame 10 is provided with a feeding channel 103 for conveying the strips 101. When conveying the strips 101, the strips 101 pass through the feeding channel straightly. The feeding mechanism 20 is used to convey the strips 101 on the material roll 100 to the feeding channel 103 straightly. The folding mechanism 70 is located at the end of the feeding channel 103 away from the feeding mechanism 20, and is used to fold the strips 101 output through the feeding channel 103 along the width direction of the strips 101. The cutting mechanism 50 is installed on the other side of the mounting frame 10, and is used to cut the strips 101 folded by the folding mechanism 70 into folded strips.

[0076] When the folding strip automatic forming device of the embodiment of the present invention is in use, the feeding mechanism 20 conveys the material on the material roll 100 to the feeding channel 103, and the strip 101 is conveyed straight along the feeding channel 103. After the strip 101 is output from the feeding channel 103, the folding mechanism 70 folds the strip 101 along the width direction, and the folded strip 101 is continuously conveyed to the cutting mechanism 50, and the cutting mechanism 50 finally cuts the folded strip 101 into folded strips 101. In this way, when the feeding mechanism 20 conveys the sticker 101 to the cutting mechanism 50 for cutting, the folding mechanism 70 folds the sticker 101 along the width direction of the sticker 101. Since the sticker 101 has been folded before cutting, the cutting mechanism 50 can cut the sticker 101 to obtain a folded sticker. The sticker 101 is automatically completed from feeding to cutting and forming, with less manual labor input, which can save labor costs. At the same time, compared with manual operations, mechanical operations are more efficient, thereby greatly improving the overall production efficiency.

[0077] In another embodiment of the present invention, Figures 2 to 4 As shown, the feeding mechanism 20 includes a plurality of material installation shafts 21 and a plurality of feeding components 22 corresponding to the plurality of material installation shafts 21. Each material installation shaft 21 is used to install a material roll 100, respectively. The discharge end of each feeding component 22 is communicated with the feed channel 103, and is used to sequentially transport the strips 101 on the material roll 100 installed on each material installation shaft 21 to the feed channel 103. Specifically, the reel of the material roll 100 is inserted into the material installation shaft 21, and the material roll 100 can rotate on the material installation shaft 21 to release the strips 101 wound on its reel, and the feeding component 22 then transports the released strips 101 to the feed channel 103.

[0078] In this way, a plurality of material installation shafts 21 and a plurality of feeding components 22 are arranged on the installation frame 10, and the discharge ends of each feeding component 22 are connected to the feeding channel 103. When in use, a plurality of material rolls 100 are respectively installed on the corresponding material installation shafts 21, and the stickers 101 on each material roll 100 can be sequentially transported to the feeding channel 103 by the corresponding feeding components 22. When all the stickers 101 on one material roll 100 are used up, the material roll 100 on another material installation shaft 21 can be used as a new one. The material source is the corresponding feeding assembly 22, and the strip 101 continues to be transported to the feeding channel 103. In this way, after a material roll 100 is used up, there is no need to wait for a new material roll 100 to be replaced. It is only necessary to switch to the material roll 100 on another material installation shaft 21. The multiple material rolls 100 on the multiple material installation shafts 21 are sequentially used as the material source of the strip 101, so that the feeding mechanism 20 can continue to perform the feeding operation while changing the material. The feeding mechanism 20 continuously supplies material, and the efficiency of the folding strip processing is effectively improved.

[0079] In another embodiment of the present invention, Figures 2 to 4 As shown, the feeding assembly 22 includes a feed roller group 221 for providing feeding power and a feed plate 222 for limiting the feeding direction. The feed plate 222 is provided with a guide groove 223 for the strip 101 to fit through and arranged parallel to the conveying direction of the strip 101. The guide groove 223 has a guide inlet 224 and a guide outlet 225 arranged opposite to each other. The feed roller group 221 is rotatably mounted on the mounting frame 10 and arranged close to the guide inlet 224. The guide outlet 225 docks with the conveying channel 103 and forms the discharge end of the feeding assembly 22. In this way, the strip 101 passes through the guide groove 223 on the feed plate 222 and is then conveyed into the conveying channel 103. The guide groove 223 can limit the conveying direction of the strip 101 to prevent the strip 101 from deviating from the conveying direction during the conveying process, thereby ensuring that the strip 101 can enter the conveying channel 103 straightly. Furthermore, in this embodiment, as Figure 4 As shown, the material guide inlet 224 is a gradually widening opening with a gradually increasing diameter, and the large diameter end of the gradually widening opening is arranged toward the feed roller group 221, so that it is more convenient for the sticker strip 101 to enter the material guide groove 223.

[0080] In another embodiment of the present invention, Figure 2 and Figure 4As shown, the feed roller group 221 includes an upper feed roller 2211 and a lower feed roller 2212 for clamping the sticker 101, and the feeding assembly 22 also includes a feed motor 226, a feed driving gear 227 and a feed driven gear 228. The feed driven gear 228 is fixedly connected to the roller shaft of the lower feed roller 2212, and the feed driving gear 227 is fixedly connected to the output shaft of the feed motor 226. The feed driving gear 227 is meshingly connected with the feed driven gear 228. The feed motor 226 drives the feed driving gear 227 to rotate, thereby driving the lower feed roller 2212 to rotate. The lower feed roller 2212 is an active roller, and the upper feed roller 2211 is a floating roller and is used to press the sticker 101. In this way, the upper feed roller 2211 rotates in the opposite direction under the action of friction, so that the sticker 101 clamped between the upper feed roller 2211 and the lower feed roller 2212 moves along its conveying direction.

[0081] Furthermore, in this embodiment, if Figure 4 As shown, the upper feed roller 2211 and the lower feed roller 2212 are symmetrically arranged on the upper and lower sides of the feed plate 222, so that the strip 101 can pass into the guide groove 223 from the middle of the guide inlet 224. In this way, the strip 101 does not contact the feed plate 222 when entering the guide groove 223, thereby avoiding wear of the strip 101.

[0082] In another embodiment of the present invention, Figure 4 As shown, the feeding assembly 22 also includes a tensioning wheel 229 with adjustable position. Specifically, the tensioning wheel 229 is arranged in a direction parallel to the strip 101. Figure 5 The horizontal position in the middle is adjustable, the tensioning wheel 229 is arranged between the feed roller group 221 and the material installation shaft 21, and the material installation shaft 21, the rotating shaft of the tensioning wheel 229 and the roller shaft of the feed roller group 221 are arranged in parallel, and the strip 101 released from the material roll 100 bypasses the tensioning wheel 229 and is then clamped and conveyed by the feed roller group 221. In this way, by adjusting the distance between the tensioning wheel 229 and the material transfer roller group 31, the tension of the strip 101 can be adjusted to prevent the loosening of the strip 101 from affecting the normal conveying of the strip 101.

[0083] Specifically, in this embodiment, Figure 2 and Figure 4As shown, a first mounting plate 17 and a second mounting plate 18 are spaced apart on the mounting frame 10, a feeding mechanism 20 is clamped between the first mounting plate 17 and the second mounting plate 18, opposite ends of an upper feed roller 2211 and a lower feed roller 2212 are respectively connected to the first mounting plate 17 and the second mounting plate 18, and a feed motor 226 is installed on the outer side of the first mounting plate 17 / the second mounting plate 18. Two supporting arms 19 that are arranged opposite to each other are also protruded from the first mounting plate 17 and the second mounting plate 18, and the material mounting shaft 21 is rotatably connected between the two supporting arms 19. Specifically, U-shaped notches 191 are opened in the two supporting arms 19 in the vertical direction, and the two opposite ends of the material mounting shaft 21 are respectively placed in the two U-shaped notches 191. The material mounting shaft 21 is easy to disassemble and assemble, and the material roll 100 is easy to replace. When the material roll 100 is installed on the material mounting shaft 21, the material mounting shaft 21 is pressed against the bottom of the U-shaped notch 191 under the action of the gravity of the material roll 100, thereby preventing the material mounting shaft 21 from escaping from the U-shaped notch 191.

[0084] In another embodiment of the present invention, Figure 2 and Figure 4 As shown, the feeding mechanism 20 includes two groups of feeding components 22, and the two groups of feeding components 22 are respectively arranged on the upper and lower sides of the length extension direction of the feeding channel 103. The two groups of feeding components 22 are standby for each other and alternately feed the stickers 101 to the feeding channel 103. The structure of the feeding mechanism 20 is relatively simple and can ensure the uninterrupted feeding of the stickers 101. Of course, in some other embodiments, the feeding mechanism 20 can also include three material installation shafts 21, and three groups of feeding components 22 are correspondingly arranged, one for use and two for standby, thereby further reducing the impact of the failure of the feeding component 22 on the feeding.

[0085] In another embodiment of the present invention, Figure 4 and Figure 5 As shown, an upper introduction plate 14 and a lower introduction plate 15 are further provided between the feed channel 103 and the feeding mechanism 20. The upper introduction plate 14 and the lower introduction plate 15 are respectively used to guide the strips 101 transported by the two feeding components 22 to enter the feed channel 103. The upper introduction plate 14 and the lower introduction plate 15 are spaced apart and form a guide gap 16 for the strips 101 to pass through. The entrance of the guide gap 16 is connected to the guide outlets 225 of the two guide grooves 223, and the outlet of the guide gap 16 is connected to the entrance of the feed channel 103. In this way, when the feeding mechanism 20 is provided with two groups of feeding components 22, the upper introduction plate 14 and the lower introduction plate 15 are provided to respectively guide the strips 101 transported by the upper feeding component 22 and the lower feeding component 22 to be transported to the feed channel 103, which can further provide the accuracy of the conveying direction of the strips 101.

[0086] Furthermore, in this embodiment, if Figure 4 and Figure 6As shown, an upper fillet is provided at the end of the upper introduction plate 14 near the feed plate 222, and the upper fillet is arranged opposite to the material guide outlet 225 of the guide groove 223 of the upper feeding assembly 22, so as to prevent the strip 101 from being scratched by the upper introduction plate 14 when entering the material introduction gap 16; a lower fillet is provided at the end of the lower introduction plate 15 near the feed plate 222, and the lower fillet is arranged opposite to the material guide outlet 225 of the guide groove 223 of the lower feeding assembly 22, so as to prevent the strip 101 from being scratched by the lower introduction plate 15 when entering the material introduction gap 16.

[0087] In another embodiment of the present invention, Figure 2 , Figure 7 and Figure 8 As shown, the folding mechanism 70 includes a traction component 72 and a folding component 71. The traction component 72 is arranged at the side of the folding component 71. The traction component 72 is used to traction and convey the sticker 101. When the traction component 72 tractions the sticker 101 through the folding component 71, the folding component 71 folds the sticker 101 along the width direction of the sticker 101. The cutting mechanism 50 is arranged at the rear end of the traction component 72 along the conveying direction of the sticker 101. The traction component 72 further conveys the sticker 101 folded by the folding component 71 to the cutting mechanism 50 for cutting, thereby forming the folded sticker 101. When in use, the traction component 72 tractions the sticker 101 to convey it forward. When conveying through the folding component 71, the folding component 71 folds the sticker 101 along the width direction. After the sticker 101 is folded, the traction component 72 conveys it to the cutting mechanism 50 at the rear end. The cutting mechanism 50 cuts the folded sticker 101 into stickers of suitable sizes. Since the sticker 101 has been folded before cutting, the sticker after cutting is a folded sticker. The folded sticker is automatically formed and can be directly placed in the storage box without manual folding by operators, thereby saving labor input and reducing labor costs. At the same time, mechanical operation can improve work efficiency compared with manual operation and improve overall production efficiency.

[0088] Furthermore, in this embodiment, if Figure 2 , Figures 7-10 As shown, the folding assembly 71 includes a supporting plate 711 for supporting the first side edge portion 1011 of the sticker 101 and a folding plate 712 for guiding the second side edge portion 1012 of the sticker 101 to overlap with the first side edge portion 1011. The supporting plate 711 is located in the feeding channel 103. The supporting plate 711 is provided with a spiral groove 7121 arranged below the supporting plate 711 and used to guide the second side edge portion 1012 to fold. The stop edge 7111 extends into the spiral groove 7121 from the side of the spiral groove 7121. The spiral groove 7121 has a groove body entrance for the second side edge portion 1012 to penetrate into and a groove body exit for the second side edge portion 1012 to penetrate out. The groove body entrance is located on one side of the stop edge 7111, and the groove body exit is located on the other side of the stop edge 7111. Figure 8 and Fig.10 As shown, the inlet of the groove is located on the left side of the stop edge 7111, and the outlet of the groove is located on the right side of the stop edge 7111. When the second side edge 1012 passes through the spiral groove 7121, it is folded from one side of the support plate 711 to the bottom of the support plate 711, so that the second side edge 1012 is close to the first side edge 1011. In addition, in this embodiment, when the first side edge 1011 of the sticker 101 is placed on the support plate 711, the stop edge 7111 is located directly above the folding line 1013 of the sticker 101. In this way, the spiral groove 7121 can guide the second side edge 1012 to be folded along the folding line 1013 until it is close to the first side edge 1011 ( Figure 1 The dotted arc in the middle is the folding path of the second side edge 1012. During the process of the traction assembly 72 conveying the sticker 101, the first side edge 1011 of the sticker 101 is supported by the support plate 711 and conveyed along the support plate 711. During the conveying process, the second side edge 1012 of the sticker 101 penetrates into the spiral groove 221. Under the guidance of the spiral groove 221 and the stopper edge 7111 of the support plate 711, the second side edge 1012 is folded to be close to the first side edge 1011. Fig. 9 , which shows the state when the second side portion 1012 is in the spiral groove 221. In this way, the sticker 101 can be folded while being transported.

[0089] Specifically, in this embodiment, Figure 8 and Fig. 9 As shown, the stop edge 7111 of the supporting plate 711 is arranged opposite to the center line of the strip 101. At this time, the folding mechanism 70 can fold the strip 101 in half, that is, the first side edge 1011 and the second side edge 1012 of the strip 101 are of equal width and are both half of the width of the strip 101. The folded strip that is cut and formed after the strip 101 is folded in half occupies less space.

[0090] More specifically, in this embodiment, if Figure 7 and Figure 8 As shown, the supporting plate 711 has a first end and a second end that are relatively arranged, and the traction component 72 pulls the strip 101 to move from the first end of the supporting plate 711 to the second end, and the groove entrance of the spiral groove 7121 is located on the side of the first end of the supporting plate 711, and the groove outlet of the spiral groove 7121 extends to the second end beyond the supporting plate 711. After the folded second side edge 1012 passes through the groove outlet of the spiral groove 7121, it is tightly attached to the bottom surface of the first side edge 1011, and the cutting mechanism 50 is arranged at the rear end of the groove outlet of the spiral groove 7121. In this way, the strip 101 can be folded to make its second side edge 1012 overlap with the first side edge 1011. After folding, the gap between the first side edge 1011 and the second side edge 1012 of the strip 101 is reduced, which makes it more convenient for the cutting mechanism 50 to cut the folded strip 101.

[0091] In another embodiment of the present invention, Figures 7 to 9 As shown, the traction assembly 72 includes a plurality of traction roller groups 721 for clamping and conveying the strip 101. Each traction roller group 721 is installed at intervals on the side of the support plate 711 away from the folding plate 712 along the conveying direction of the strip 101. Each traction roller group 721 sequentially clamps the first side edge 1011 extending out of the side of the support plate 711, so that the strip 101 is conveyed along the length extension direction of the support plate 711. When the strip 101 is conveyed, the portion of the first side edge 1011 close to the folding line 1013 is placed on the support plate 711, and the side edge portion away from the folding line 1013 extends out of the support plate 711 and is used to be clamped by each traction roller group 721. The traction roller group 721 clamps the side edge to pull the strip 101 to move along the support plate 711, so that the second side edge 1012 can be folded under the guidance of the spiral groove 7121, ensuring that the strip 101 is folded while being conveyed.

[0092] Furthermore, in this embodiment, if Figure 8 and Fig. 9 As shown, the traction roller group 721 includes a traction active roller 7211 and a traction floating roller 7212 which are rotatably mounted on the mounting frame 10. The traction floating roller 7212 is arranged above the traction active roller 7211 in parallel and forms a traction clamping gap 7213 with the traction active roller 7211. The traction clamping gap 7213 is arranged opposite to the supporting plate 711 so that the side edge of the first side edge portion 1011 extends into the traction clamping gap 7213, and the traction floating roller 7212 abuts against the supporting plate 711. The pressure extends to the side within the traction clamping gap 7213 so that the strip 101 is clamped between the traction active roller 7211 and the traction floating roller 7212; the traction active roller 7211 rotates and cooperates with the traction floating roller 7212 to clamp the side of the first side edge portion 1011 of the strip 101, thereby conveying the strip 101 forward, and when the strip 101 moves through the supporting plate 711 and the folding plate 712, the second side edge portion 1012 is folded to be close to the first side edge portion 1011.

[0093] Specifically, in this embodiment, Figures 8 to 11As shown, the mounting frame 10 is provided with a third mounting plate 701, a fourth mounting plate 702 and a fifth mounting plate 703, the third mounting plate 701, the fourth mounting plate 702 and the fifth mounting plate 703 are all arranged parallel to the supporting plate 711, the third mounting plate 701 and the fourth mounting plate 702 are arranged at intervals up and down and close to the supporting plate 711, and a material passing gap 704 is formed for the side edge of the first side edge portion 1011 to pass through, and the fifth mounting plate 703 is arranged on the side of the mounting frame 10 away from the stop plate 711; The traction active roller 7211 is rotatably installed between the fourth mounting plate 702 and the fifth mounting plate 703, the traction floating roller 7212 is rotatably installed between the third mounting plate 701 and the fifth mounting plate 703, the traction clamping gap 7213 is arranged opposite to the feeding gap 704, and the side edge of the first side edge portion 1011 of the strip 101 passes through the feeding gap 704 and then extends into the traction clamping gap 7213, thereby ensuring that the traction active roller 7211 and the traction floating roller 7212 clamp and convey the strip 101.

[0094] In another embodiment of the present invention, Figure 3 and Figure 7 As shown, the traction assembly 72 also includes a traction drive motor 722, which is driven and connected to a traction active roller 7211 of a traction roller group 721. Each traction roller group 721 is connected through a synchronous belt 34. The traction drive motor 722 drives the traction active roller 7211 connected thereto to rotate, and the traction active roller 7211 transmits the torque to other traction roller groups 721 step by step through the synchronous belt 34. In this way, the traction drive motor 722 can drive each traction roller group 721 to rotate and convey the strip 101 when it is started. Only one traction drive motor 722 is required to drive all the traction roller groups 721 to rotate and feed, which can effectively save electricity consumption. In addition, the linkage of each traction roller group 721 can ensure that each traction roller group 721 conveys the strip 101 at the same rotation speed, thereby avoiding that two adjacent traction roller groups 721 pull the strip 101 due to different rotation speeds.

[0095] Specifically, in this embodiment, Figure 3 and Figure 7 As shown, the traction active roller 7211 and the traction floating roller 7212 of each traction roller group 721 transmit torque through the transmission gear 32, and the torque is transmitted between two adjacent traction roller groups 721 by belt transmission. The belt transmission structure includes a synchronous wheel 33 and a synchronous belt 34, etc. Its specific transmission method is the same as the ordinary belt transmission method, which will not be described here. Of course, in other more embodiments, multiple traction drive motors 722 can also be set to drive different traction roller groups 721 to rotate and transport the sticker 101. The design can be selected according to the actual situation. The driving method of each traction roller group 721 is not limited here.

[0096] In another embodiment of the present invention, Figure 2 , Figure 7 and Figure 8 As shown, the folding mechanism 70 also includes a guide plate 73 for limiting the traction feeding direction. A feed trough 731 is provided on the guide plate 73 for the strip 101 to fit through and is arranged parallel to the conveying direction of the strip 101. The feed trough 731 has a feed port 732 and a discharge port 733 arranged opposite to each other. The feed port 732 is connected to the entrance of the spiral groove 7121. The traction roller group 721 is arranged close to the discharge port 733, and the discharge port 733 is connected to the traction clamping gap 7213. In this way, after the strip 101 is output from the conveying channel 103, it passes through the feed trough 731 on the guide plate 73 and is then conveyed to the traction clamping gap 7213. The feed trough 731 can limit the conveying direction of the strip 101, preventing the strip 101 from deviating from the conveying direction during the conveying process, thereby ensuring that the strip 101 can be clamped straight by the traction roller group 721. Preferably, as Figure 8 , Fig. 9 and Fig.11 As shown, the feed opening 732 is a gradually widening opening with a gradually increasing diameter, and the large diameter end of the gradually widening opening is arranged away from the traction roller group 721, so that it is more convenient for the sticker strip 101 to enter the feed trough 731.

[0097] In another embodiment of the present invention, Figure 8 and Fig. 9 As shown, the upper edge of the slot of the feed slot 731 is folded upward and extended to form a first stop plate 734, and the lower edge of the slot of the feed slot 731 is folded downward and extended to form a second stop plate 735. The first stop plate 734 abuts against the ends of the first mounting plate 17 and the third mounting plate 701, and the second stop plate 735 abuts against the ends of the second mounting plate 18 and the third mounting plate 701, thereby limiting the installation position of the guide plate 73. The first end of the support plate 711 It is connected to the second stop plate 735, and the upper edge and lower edge of the entrance of the spiral groove 7121 are respectively connected to the first stop plate 734 and the second stop plate 735, or the upper edge of the entrance of the spiral groove 7121 is opposite to the first stop plate 734. After the strip 101 passes through the discharge port 733, the supporting plate 711 and the folding plate 712 begin to guide the strip 101 to fold, which is beneficial to shorten the overall conveying stroke of the strip 101 and make the overall structure of the device more compact.

[0098] Preferably, in this embodiment, the supporting plate 711, the folding plate 712 and the material guide plate 73 are integrally formed, and no subsequent assembly is required, which is more convenient to use.

[0099] In another embodiment of the present invention, Figure 3 , Fig.12 and Fig.13As shown, the cutting mechanism 50 includes an upper cutter 51, a lower cutter 52, an upper drive motor 53 and a lower drive motor 54. A cutting mounting plate 55 perpendicular to the conveying direction of the sticker 101 is arranged on the mounting frame 10. A cutting feed port 551 is opened on the cutting mounting plate 55 for the folded sticker 101 to pass through, and the cutting feed port 551 is arranged opposite to the groove body outlet of the spiral groove 7121; the upper cutter 51 and the lower cutter 52 are both slidably mounted on the cutting mounting plate 55, and the upper cutter 51 and the lower cutter 52 are respectively located on the upper and lower sides of the cutting feed port 551, the upper drive motor 53 and the lower drive motor 54 are both mounted on the cutting mounting plate 55, and are respectively connected to the upper cutter 51 and the lower cutter 52 to drive the upper cutter 51 and the lower cutter 52 to move toward each other, thereby cutting the folded sticker 101 passing through the cutting feed port 551. Specifically, when the length of the folded strip 101 that moves through the support plate 711 and passes through the cutting and feeding port 551 meets the size requirement of the folded strip, the upper drive motor 53 and the lower drive motor 54 are started and drive the upper cutter 51 and the lower cutter 52 to move toward each other, thereby cutting the folded strip 101 to form a folded strip. After one cutting action is completed, the upper drive motor 53 and the lower drive motor 54 drive the upper cutter 51 and the lower cutter 52 to move in opposite directions. When the length of the folded strip 101 that passes through the cutting and feeding port 551 meets the size requirement of the folded strip again, the next cutting operation is performed. Moreover, after one cutting action, the strip 101 is completely separated from the upper cutter 51 and the lower cutter 52 and will not adhere to the upper cutter 51 or the lower cutter 52, thereby not hindering the continued transportation of the strip 101, and the cutting is smoother.

[0100] Specifically, in this embodiment, Figure 3 and Figure 7 As shown, the lengths of the blades 511 of the upper cutter 51 and the lower cutter 52 are both greater than or equal to the width of the folded sticker strip 101 , so as to ensure that the upper cutter 51 and the lower cutter 52 can cut the folded sticker strip 101 .

[0101] Furthermore, in this embodiment, the blade 511 of the upper cutter 51 is arranged opposite to the blade 511 of the lower cutter 52 (not shown), so that when cutting, the upper drive motor 53 and the lower drive motor 54 drive the blades 511 of the upper cutter 51 and the lower cutter 52 to abut against each other, and the folded sticker 101 can be cut. Fig.10 and Fig.11 As shown, the blade 511 of the upper cutter 51 can also be arranged alternately with the blade 511 of the lower cutter 52, and when the upper cutter 51 and the lower cutter 52 cut the folded sticker 101, the back of the blade 521 of the upper cutter 51 is close to the back of the blade 521 of the lower cutter 52, so that when the upper cutter 51 and the lower cutter 52 perform the cutting action, they can cut the folded sticker 101 like scissors.

[0102] In another embodiment of the present invention, Fig.12 and Fig.13 As shown, the cutting mechanism 50 further includes a sliding connection structure 57 for slidingly connecting the upper cutter 51 and the lower cutter 52 to the cutting installation plate 55, and the sliding connection structure 57 includes a sliding rail 571 and a slider 572 that are slidably matched, and the slider 572 is provided with a sliding groove that is adapted to be engaged with the sliding rail 571. The sliding rail 571 is convexly arranged on the cutting installation plate 55 along the sliding direction of the upper cutter 51 and the lower cutter 52, and the slider 572 is arranged at the position where the upper cutter 51 and the lower cutter 52 face the sliding rail 571, and the two opposite sides of the cutting installation plate 55 are respectively provided with a sliding rail 571, and the two ends of the upper cutter 51 facing the two sliding rails 571 and the two ends of the lower cutter 52 facing the two sliding rails 571 are both provided with sliders 572, so that the upper cutter 51 and the lower cutter 52 slide more smoothly.

[0103] In another embodiment of the present invention, Figure 7 , Fig.12 and Fig.13 As shown, the cutting mechanism 50 also includes a cutting feeding assembly 56 for conveying the folded sticker 101 to the cutting feeding port 551. The cutting feeding assembly 56 includes a cutting active roller 561 and a cutting floating roller 562 which are rotatably mounted on the mounting frame 10. The cutting floating roller 562 is arranged above the cutting active roller 561 in parallel and forms a cutting clamping gap 5611 between the cutting active roller 561 and the cutting active roller 561 for the folded sticker 101 to pass through. The cutting clamping gap 5611 is arranged opposite to the cutting feeding port 551. The cutting floating roller 562 presses against the passing strip 101. The folded sticker strip 101 is arranged in the cutting clamping gap 5611, so that the folded sticker strip 101 is clamped between the cutting active roller 561 and the cutting floating roller 562; the cutting active roller 561 rotates and cooperates with the cutting active roller 561 to clamp the folded sticker strip 101 conveyed by the conveying traction assembly 72, and when the folded sticker strip 101 moves to pass through the cutting feed port 551, the upper drive motor 53 and the lower drive motor 54 start to drive the upper cutter 51 and the lower cutter 52 to move toward each other, thereby cutting the folded sticker strip 101. Specifically, in this embodiment, the roller shafts of the cutting active roller 561 and the cutting floating roller 562 are arranged parallel to the blades 511 of the upper cutter 51 and the lower cutter 52.

[0104] Going a step further, Figure 7 , Fig.12 and Fig.13 As shown, two connecting plates 552 are protruded from opposite sides of the cutting installation plate 55 facing the folding mechanism 70 . The two connecting plates 552 are arranged in parallel and spaced apart. The cutting active roller 561 and the cutting floating roller 562 are rotatably installed between the two connecting plates 552 .

[0105] In another embodiment of the present invention, Figure 3 , Figure 7 and Fig.12 As shown, the cutting and feeding assembly 56 also includes a cutting and feeding motor 563, and the output shaft of the cutting and feeding motor 563 is drivingly connected to the cutting active roller 561 to drive the cutting active roller 561 to rotate and convey the folded sticker strip 101. Specifically, in the present embodiment, the cutting and feeding motor 563 and the traction drive motor 722 are the same motor, and a synchronous wheel 33 is sleeved on the roller shaft of the cutting active roller 561, and the synchronous wheel 33 is connected to the traction active roller 7211 of the traction roller group 721 at the end of the traction roller group 721 close to the cutting mechanism 50 through a synchronous belt 34, and the traction active roller 7211 then transmits the torque to other traction roller groups 721 step by step through gear transmission and belt transmission. In this way, the cutting and feeding motor 563 (traction drive motor 722) drives the cutting and feeding assembly 56 and the traction roller group 721 to synchronously rotate and transport the folded strip 101 before and after. In this way, only one motor is needed to complete the feeding, folding and cutting of the strip 101, and the overall structure of the device is simple and easy to operate.

[0106] In another embodiment of the present invention, Figure 2 and Fig.14 As shown, the folded strip automatic forming device also includes a half-cutting mechanism 40 for processing a half-cut line of the strip 101 entering the feeding channel 103. Two side panels 11 are arranged on the mounting frame 10 in a direction parallel to the feeding direction of the strip 101. A strip support plate 13 for supporting the strip 101 is sandwiched between the two side panels 11. The strip support plate 13 and the two side panels 11 are jointly arranged to form the feeding channel 103. The half-cutting mechanism 40 is installed in the feeding channel 103. The feeding mechanism 20 and the folding mechanism 70 are respectively arranged at both ends of the strip support plate 13. In this way, the strip support plate 13 is arranged to support the strip 101, and the strip 101 is laid flat on the strip support plate 13, so as to prevent the strip 101 from being deformed due to sagging due to gravity. The two side panels 11 can prevent the strip 101 from shaking left and right along the feeding direction, so as to ensure that the strip 101 is always transported in a straight line.

[0107] When in use, the feeding mechanism 20 conveys the material on the material roll 100 to the feeding channel 103. When the sticker 101 moves through the feeding channel 103, the half-cutting mechanism 40 performs half-cutting processing on the sticker 101 in the feeding channel 103. After the half-cutting processing is completed, the sticker 101 is output from the feeding channel 103 to the folding mechanism 70 and the cutting mechanism 50 in sequence. In the process of the feeding mechanism 20 conveying the sticker 101 to the cutting mechanism 50 for cutting, the half-cutting mechanism 40 facilitates the processing of the half-cutting line on the sticker 101. In this way, the processing of the half-cutting line is integrated into the cutting process of the folding sticker. The folding stickers loaded in the storage box are all provided with the half-cutting line, which makes it more convenient for the user to tear the adhesive layer of the folding sticker from the bottom paper layer. In addition, the half-cutting processing is completed while the sticker 101 is conveyed and cut into the folding sticker, and there is no need to set up an independent half-cutting processing process, which simplifies the processing steps of the folding sticker and improves the production efficiency of the folding sticker.

[0108] Furthermore, in this embodiment, if Figure 2 , Figure 3 and Fig.14 As shown, the half-cutting mechanism 40 includes a half-cutter 41, a cutter fixed shaft 42 and a half-cutting driving motor 43. The half-cutter 41 is fixed on the cutter fixed shaft 42. The blade 511 of the half-cutter 41 abuts against the sticker 101, and the cutting depth of the blade 511 of the half-cutter 41 is equal to the thickness of the adhesive layer on the sticker 101. The cutter fixed shaft 42 is rotatably mounted on one of the side plates 11. The half-cutting driving motor 43 is mounted on the bottom of the support strip 13 away from the sticker 101 and is drivingly connected to the cutter fixed shaft 42. The half-cutting driving motor 43 drives the cutter fixed shaft 42 to rotate, thereby driving the half-cutter 41 to rotate and cut the sticker 101 to form a half-cut line. Specifically, in this embodiment, the half-cutter 41 is preferably a disc knife, and the half-cutting driving motor 43 drives the cutter fixed shaft 42 to reverse relative to the conveying direction of the sticker 101, thereby completing the half-cutting line processing. The half-cutting mechanism 40 has a simple structure, simple processing action, and high processing efficiency.

[0109] Furthermore, if Figure 2 and Fig.15 As shown, the axis of the cutter fixing shaft 42 is perpendicular to the conveying direction of the strip 101, that is, the cutter fixing shaft 42 is vertically installed on one of the side plates 11, and the half cutter 41 abuts against the strip 101 at the end position of the strip 101, and the above-mentioned half-cut line is processed at the end of the strip 101.

[0110] In another embodiment of the present invention, Figure 2 and Fig.15As shown, a half-cut mounting plate 37 is movably mounted on the side plate 11 on which the cutter fixing shaft 42 is mounted, and the half-cutting knife 41 is mounted on the half-cutting mounting plate 37. The half-cutting mounting plate 37 can move up and down on the side plate 11 along the direction perpendicular to the sticker 101, so as to adjust the distance between the blade 511 of the half-cutting knife 41 and the sticker 101. When the stickers 101 to be cut are different and the thickness of the adhesive layer on the sticker 101 is different, the installation position of the half-cutting mounting plate 37 is adjusted, so that the distance between the blade 511 of the half-cutting knife 41 and the sticker 101 can be adjusted, thereby achieving the purpose of adjusting the cutting depth, so that the half-cutting mechanism 40 of this embodiment can cut stickers 101 of different thicknesses or adhesive layers of different thicknesses on the same sticker 101, and has a wider range of applications and is more flexible and convenient to use. For example, in this embodiment, a connecting long hole perpendicular to the strip 101 can be set on the side panel 11, and the half-cut mounting plate 37 is fastened to the side panel 11 by fasteners such as connecting bolts. When the fasteners fasten the half-cut mounting plate 37 at different positions of the connecting long hole, the half-cut mounting plate 37 can move up and down in the direction perpendicular to the strip 101.

[0111] Furthermore, if Figure 2 and 15 As shown, the half-cutting mechanism 40 also includes a screw micrometer 36 for measuring the moving distance of the half-cutting knife 41. Since the thickness of the adhesive layer is generally relatively small and the thickness is known before cutting, the screw micrometer 36 is set to measure the distance between the half-cutting knife 41 and the sticker 101, so as to quickly and accurately adjust the cutting depth of the half-cutting knife 41. Specifically, the screw micrometer 36 is installed on the side plate 11 on which the cutter fixing shaft 42 is installed, and the measuring screw of the screw micrometer 36 is perpendicular to the plane where the sticker 101 is located. The half-cutting mounting plate 37 is provided with a positioning part that is positioned and matched with the screw micrometer 36. The probe of the screw micrometer 36 is directly opposite to the positioning part and can be moved to abut against the positioning part. When in use, the moving distance of the half-cutting knife 41 can be obtained by measuring the moving distance of the positioning part relative to the probe. The reference is obvious and the measurement is convenient.

[0112] Preferably, in this embodiment, if Fig.15As shown, the half-cut mechanism 40 includes two micrometer screws 36, two positioning ears 371 are protruding from the opposite sides of the half-cut mounting plate 37 parallel to the sticker strip 101, and two connecting ears 111 are provided on the side plate 11 on which the cutter fixing shaft 42 is installed. The two connecting ears 111 are respectively located directly below the two positioning ears 371, and the two micrometer screws 36 are respectively installed on the two connecting ears 111, and the two positioning ears 371 respectively form positioning parts that are positioned and matched with the two micrometer screws 36. The two positioning ears 371 are provided on the two sides of the half-cut mounting plate 37 and serve as positioning parts at the same time, and the two micrometer screws 36 are provided to measure the moving distance of the two sides of the half-cut mounting plate 37 at the same time, which can effectively prevent the half-cut mounting plate 37 from being skewed, and avoid the deviation between the actual moving distance of the blade 511 of the half-cutting knife 41 and the measured distance, thereby ensuring that the position movement of the half-cutting knife 41 is more accurate.

[0113] In another embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the folded strip automatic forming device also includes a material transfer component 30 for conveying the strip 101 in the feed channel 103 to the material guide trough 223, and the material transfer component 30 includes a plurality of material transfer roller groups 31 for clamping the strip 101, and each material transfer roller group 31 is installed in the feed channel 103 at intervals along the conveying direction of the strip 101, and each material transfer roller group 31 clamps the strip 101 in sequence along the conveying direction of the strip 101, thereby pulling the strip 101 to move in the feed channel 103. Specifically, in the present embodiment, the support plate 13 is provided with a plurality of installation notches 131 at intervals along the conveying direction of the strip 101, and each of the transfer roller groups 31 is installed in each installation notch 131 correspondingly, and clamps the strip 101 correspondingly in each installation notch 131, and each transfer roller group 31 includes an upper transfer roller 311 and a lower transfer roller 312, each of the transfer rollers 311 is installed in parallel above the support plate 13, and each of the lower transfer rollers 312 is installed in parallel below the support plate 13.

[0114] Furthermore, in this embodiment, if Figure 2 , Figure 3 and Figure 4As shown, the material transfer assembly 30 also includes a material transfer motor 35, which is driven and connected to a lower material transfer roller 312 of a material transfer roller group 31 arranged at a middle position. The material transfer roller group 31 then transmits the driving force of the feeding motor to adjacent material transfer roller groups 31 step by step by means of gear transmission and belt transmission. In this way, power is transmitted between each material transfer roller group 31 by means of gear transmission and belt transmission. Only one material transfer motor 35 is required to drive all the material transfer roller groups 31 to rotate and feed materials, which can effectively save electricity consumption. Moreover, the linkage of each material transfer roller group 31 can also ensure that each material transfer roller group 31 conveys the sticker 101 at the same rotation speed, thereby avoiding that the two material transfer roller groups 31 pull the sticker 101 due to different rotation speeds. It is only necessary to ensure that the relevant structures of the material transfer roller group 31 and the belt transmission are exactly the same. Specifically, in this embodiment, the torque is transmitted between the upper transfer roller 311 and the lower transfer roller 312 of each transfer roller group 31 through the transmission gear 32, and the torque is transmitted between two adjacent transfer roller groups 31 through belt transmission. The belt transmission structure includes a synchronous belt 34 and a synchronous wheel 33.

[0115] In some other embodiments, Figure 2 and Figure 3 As shown, the half-cut drive motor 43 and the feed motor 35 can share a motor, and the half-cut drive motor 43 (feed motor 35) is connected to the lower feed roller 312 of the feed roller group 31 at the middle position by belt transmission, and the lower feed roller 312 transmits the torque to the cutter fixed shaft 42 by gear transmission, and the lower feed roller 312 transmits the torque to the two adjacent feed roller groups 31 by belt transmission. In this way, the half-cut drive motor 43 (feed motor 35) drives each feed roller group 31 to rotate and transport the sticker 101, and drives the cutter fixed shaft 42 to rotate and process the above-mentioned half-cut line on the sticker 101. In this way, only one motor is needed to complete the feeding of the sticker 101 and the processing of the half-cut line, and the overall structure of the device is simple and the operation is more convenient.

[0116] In another embodiment of the present invention, Figure 2 , Figure 3 and Fig.16As shown, the last upper feed roller 311 and lower feed roller 312 in the feed channel 103 disposed near the guide plate 73 are also provided with a pre-pressing member 80 for preforming a folding line 1013. The pre-pressing member 80 is a rigid pressing ring sleeved on the roller shaft of the upper feed roller 311 / lower feed roller 312. The rigid pressing ring is concavely formed with an annular pressing groove 81, and the two annular pressing grooves 81 are disposed opposite to each other. When the strip 101 is transported to pass through the pre-pressing member 80, the pre-pressing member 80 squeezes out a folding line 1013 on the strip 101 that matches the shape of the annular pressing groove 81. In this way, when the folding mechanism 70 folds the strip 101, the strip 101 can be folded into place more quickly and accurately. Specifically, in this embodiment, the annular pressing ring on the pre-pressing member 80 is disposed directly opposite to the folding line 1013 of the strip 101.
