Description

Technical Field

[0001] The present application relates to the technical field of paper distribution and transportation, and in particular to a cone-shaped paper sleeve forming device for cone packaging. Background Art

[0002] Sugar cones are typically filled with ice cream or other desserts in a conical biscuit shell. To maintain freshness and hygiene, they are typically wrapped in a conical paper sleeve. Currently, paper sleeve forming machines are commonly used to efficiently form the cone sleeves used for sugar cone packaging.

[0003] Conventional paper sleeve forming machines include a conveying assembly for conveying stacked sheets of paper, a single-layer paper dispensing assembly for separating single-layer sheets from the stack, a gluing assembly for gluing the single-layer sheets, a forming assembly for rolling the single-layer sheets into a conical sleeve, and a dispensing assembly for dispensing the conical sleeve. These machines are capable of processing multiple stacked fan-shaped sheets of paper into a conical sleeve consisting of single-layer sheets. The single-layer paper dispensing assembly in related art typically uses a friction roller to separate the topmost single sheet from the stack, thereby separating the sheets one by one and conveying the single-layer sheets.

[0004] However, when the friction roller distributes multiple layers of stacked paper, adjacent sheets of paper are prone to adhesion due to the thinness of the paper. When the friction roller realizes friction driving, it is easy to drive multiple sheets of paper to move at the same time, affecting the processing quality of subsequent processes. It is also easy to cause multiple sheets of paper below to shift and scatter, causing the horizontal position of the stacked paper to change and the positioning accuracy to decrease, thereby increasing the difficulty of paper distribution and making the distribution and transportation of single-layer paper unreliable.

[0005] The above-mentioned related art has the defect of poor reliability of paper distribution during the cone-shaped paper sleeve forming process. Summary of the Invention

[0006] In order to improve the problem of poor paper distribution reliability during the cone-shaped paper sleeve forming process of the sugar cone, the present application provides a cone-shaped paper sleeve forming device for sugar cone packaging.

[0007] The cone-shaped paper sleeve forming device for cone packaging provided in this application adopts the following technical solution:

[0008] A cone-shaped paper sleeve forming device for cone packaging, comprising: a paper separating mechanism, the paper separating mechanism comprising a lifting assembly, a limiting assembly, an air blowing assembly, a suction assembly and a conveying assembly, a plurality of stacked papers forming a paper pile, the lifting assembly being used to support the paper pile and drive the paper pile to move upward so that the height of the top paper of the paper pile remains unchanged, the limiting assembly and the air blowing assembly are each provided with two groups, the two groups of limiting assemblies are respectively arranged on both sides of the lifting assembly, the lifting assembly is connected to the limiting assembly, so that when the lifting assembly drives the paper pile to move upward, the limiting assembly moves back and forth horizontally, the limiting assembly can abut against the side of the paper pile to limit the paper pile horizontally through the limiting assembly, the air blowing assembly The component is arranged on the side where the limiting component can abut against the paper pile, and the blowing component is used to blow air to the side of the paper pile to separate the paper on the top layer of the paper pile from the paper pile. The limiting component drives the blowing component to move, so that the horizontal distance between the blowing component and the side of the paper pile changes periodically. The conveying component is arranged on one side of the lifting component, and the suction component is arranged at the input end of the conveying component. The suction component is used to suck the paper on the top layer of the paper pile to the conveying component to transport a single sheet of paper through the conveying component; a gluing and molding mechanism, the gluing and molding mechanism cooperates with the output end of the conveying component, and the gluing and molding mechanism is used to glue the paper and shape it into a conical paper sleeve.

[0009] By adopting the above technical solution, the lifting component supports the paper pile and adjusts its position as the height of the paper pile itself changes, so that the height of the paper on the top layer of the paper pile remains unchanged, so that the paper on the top layer of the paper pile is always at a suitable height to be separated; the limiting component moves back and forth horizontally as the lifting height of the paper pile by the lifting component changes, so as to limit the paper pile horizontally, thereby reducing the risk of the remaining paper in the paper pile being scattered due to the separation of the top layer of paper, and reducing the difficulty of paper distribution by improving the positioning accuracy of the paper in the paper pile. The suction component absorbs the separated single paper and sends it to the conveying component, so that the single paper on the top layer of the paper pile can be reliably conveyed to the conveying component, thereby ensuring the continuous supply of paper; the single layer of paper is conveyed to the gluing and molding mechanism through the conveying component, and the gluing and molding mechanism works closely with the conveying component. , so that each piece of paper can be accurately coated with glue and finally formed into a conical paper sleeve; because the blowing component is arranged on the limiting component, the blowing component can be driven by the limiting component to move back and forth horizontally, thereby causing the horizontal spacing between the blowing component and the paper pile to change periodically. When the blowing component is far from the paper pile, the blown area of ​​the paper pile is large, and the blowing effect is dispersed, which helps to reduce the adhesion between multiple sheets of paper in the paper pile; when the distance between the blowing component and the paper pile is close, the blown area of ​​the paper pile is small and the blowing effect is concentrated, which further reduces the adhesion of the top layer of paper in the paper pile, thereby reliably separating the top layer of paper in the paper pile, and combined with the suction force of the suction component, the top layer of paper in the paper pile can be reliably distributed, reducing the problem of multiple layers of paper being sucked out at the same time due to paper adhesion. The device can efficiently and stably distribute and transport multiple stacked sheets of paper one by one to the gluing and forming mechanism, improving production efficiency while significantly improving the stability of product quality.

[0013] By adopting the above technical solution, the sliding member can move horizontally under the action of the pushing member, so that the sliding member can abut the paper stack, thereby realizing horizontal limitation of the paper stack, ensuring the neatness of the paper stack, improving the positioning accuracy of the top layer of paper in the paper stack, and reducing the problem of reduced separation reliability caused by paper deviation; after the pushing member releases the pushing action on the sliding member, the elastic member enables the sliding member to quickly reset away from the side of the paper stack after completing the paper stack sorting action, thereby keeping the paper stack neat by intermittently pushing the paper stack.

[0016] Optionally, the air blowing assembly is offset to one side of the sliding member capable of abutting the paper stack, the air blowing assembly is arranged at one end of the sliding member close to the conveying assembly, the side of the sliding member away from the fixed member is provided with a groove, the air blowing assembly is arranged in the groove, and the horizontal depth of the groove is greater than the thickness of the air blowing assembly, so that the air blowing assembly is recessed in the sliding member.

[0017] By adopting the technical scheme, the air blowing assembly is offset to one end of the sliding member close to the conveying assembly, so that the air blowing assembly can blow air to the edge of the uppermost paper sheet of the paper stack close to the conveying assembly, thereby effectively reducing the paper sticking phenomenon and improving the paper distribution efficiency; meanwhile, the groove on the sliding member forms a channel at the front end of the air blowing direction of the air blowing assembly, thereby reducing the risk of forming turbulence in the air blowing direction when the horizontal distance between the air blowing assembly and the paper stack is far, and improving the concentration of the air blowing effect when the horizontal distance between the air blowing assembly and the paper stack is close, so that the uppermost paper sheet of the paper stack close to the conveying assembly can have a vertical gap with the lower paper stack, so that the uppermost paper sheet of the paper stack can be reliably distributed.

[0019] By adopting the technical scheme, the adjusting assembly can flexibly adjust the angle of the rotating part, so as to adapt to paper sheets of different sizes and improve the application range and flexibility of the equipment. The relative positioning design between the limiting part and the supporting part enables the rotating part to stably maintain the adjusted angle, thereby avoiding the change of the angle of the rotating part due to vibration or other factors during use and affecting the paper distribution effect.

[0020] Optionally, the adjustment assembly includes a telescopic drive member and a push member, the fixed end of the telescopic drive member is arranged on the support assembly, the telescopic end of the telescopic drive member is connected to the first end of the push member, and the second end of the push member is used to push the rotating part away from one end of the limiting part.

[0021] By adopting the above technical solution, the telescopic driving member provides stable power output, so that the pushing member can push the rotating part away from one end of the limiting part, thereby adjusting the posture of the sliding member and optimizing the paper distribution effect.

[0022] Optionally, the support portion is provided with a rotating rod, the rotating rod is rotatably connected to the rotating portion, and a torsion spring is provided between the rotating rod and the rotating portion to enable the rotating portion to rotate and reset.

[0025] The above-mentioned technical solution improves the efficiency and stability of paper conveying. Specifically, the conveying platform is located at the rear end of the lifting assembly, ensuring that the paper is smoothly conveyed to the gluing and forming mechanism after being sucked out of the paper pile. The conveying drive is connected to the connecting shaft, enabling the conveying roller on the connecting shaft to operate stably and reliably, allowing the paper to be clamped and conveyed between the conveying roller and the conveying platform. Through the cooperation of the suction assembly, the conveying roller and the conveying platform, single-layer paper can be conveyed, ensuring continuous paper transportation.

[0027] By adopting the above technical solutions, the vertical telescopic part drives the downward pressing part to move vertically to adjust the vertical position of the downward pressing part, so that the downward pressing part can reliably limit the vertical movement distance of the paper, prevent the paper from deviating or overlapping due to excessive vertical freedom, and ensure that the paper smoothly enters the subsequent process; the downward pressing assembly is arranged one-to-one corresponding to the conveying roller, and the downward pressing assembly is arranged between the suction assembly and the conveying roller, so that the downward pressing assembly is away from the suction assembly while limiting the vertical position of the paper, reducing the influence of the blowing separation effect on the uppermost layer of paper due to vertical limiting.

[0038] The following is combined with Figure 1 -Attached Figure 4 The present application is further described in detail. In this embodiment, unless otherwise specified, the terms "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, and can be understood based on the specific circumstances.

Moreover, in the description of this embodiment, the terms "above", "below", "left", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply 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 this application. Unless otherwise specified, orientation words such as "inside" and "outside" used in this application refer to the outlines of the corresponding components themselves.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present application discloses a cone-shaped paper sleeve forming device for cone packaging (hereinafter referred to as "device"). The device includes a paper separation mechanism and a gluing and forming mechanism, which are used to realize the distribution and transportation of single-layer paper and further glue-forming the single-layer paper.

[0041] The paper separating mechanism comprises a lifting assembly 1, a limiting assembly 2, a blowing assembly 3, a sucking assembly 4 and a conveying assembly 5. The several paper sheets are stacked to form a paper stack. The lifting assembly 1 is used for supporting the paper stack and moving the paper stack upward, so as to adjust the position of the paper stack with the change of the height of the paper stack, and keep the height of the uppermost paper sheet of the paper stack unchanged, so that the uppermost paper sheet of the paper stack is always at a suitable separating height.

[0042] As shown in Figure 1 , Figure 2 and Figure 3 , the limiting assembly 2 and the blowing assembly 3 are provided with two groups and one-to-one correspondence. The two groups of limiting assemblies 2 are arranged on the two sides of the lifting assembly 1, so as to horizontally limit the side surface of the paper stack. The lifting assembly 1 is connected with the limiting assembly 2, so that the limiting assembly 2 moves horizontally reciprocatingly when the lifting assembly 1 moves the paper stack upward. The limiting assembly 2 can abut against the side surface of the paper stack, so as to horizontally limit the paper stack by the limiting assembly 2. In the conveying direction of the paper sheet, the conveying assembly 5 is arranged at the front end of the lifting assembly 1, and the sucking assembly 4 is arranged at the input end of the conveying assembly 5. The sucking assembly 4 is used for sucking the uppermost paper sheet of the paper stack to the conveying assembly 5, and conveying the single paper sheet to the gluing and forming mechanism by the conveying assembly 5.

[0043] As shown in Figure 1 , Figure 2 and Figure 3 , the limiting assembly 2 moves horizontally reciprocatingly with the change of the lifting height of the lifting assembly 1, so as to horizontally limit the paper stack, reduce the risk of disorder of the remaining paper sheets of the paper stack caused by the separation of the uppermost paper sheet, improve the positioning accuracy of the paper sheets in the paper stack, reduce the difficulty of paper sheet distribution, and suck the separated single paper sheet into the conveying assembly 5 by the sucking assembly 4, so that the single paper sheet on the uppermost layer of the paper stack can be reliably conveyed to the conveying assembly 5, and the continuous supply of the paper sheet is ensured.

[0044] The gluing and forming mechanism (not shown in the figure) cooperates with the output end of the conveying assembly 5. The gluing and forming mechanism is used for gluing and forming the paper sheet into a conical paper sleeve. The single layer of paper sheet is conveyed to the gluing and forming mechanism by the conveying assembly 5. The gluing and forming mechanism cooperates with the conveying assembly 5, so that each paper sheet can be accurately subjected to gluing treatment, and finally formed into a conical paper sleeve. The gluing and forming mechanism can select a suitable type in the prior art according to the needs, which can realize the gluing and winding forming of the paper sheet into a conical paper sleeve. Since there are related structures, the specific structure and implementation principle will not be described here.

[0045] As shown in Figure 1 , Figure 2 and Figure 3As shown, the blow assembly 3 is located on the side of the paper stack where the limit assembly 2 can contact the paper stack. The limit assembly 2 drives the blow assembly 3, causing it to move horizontally back and forth under the influence of the limit assembly 2, thereby causing the horizontal distance between the blow assembly 3 and the paper stack to change periodically. The blow assembly 3 is used to blow air against the side of the paper stack to separate the top sheets of the stack from the stack. When the horizontal distance between the blow assembly 3 and the paper stack is large, the blown area of ​​the paper stack is large, and the blowing effect is dispersed, which helps to reduce the adhesion between the multiple sheets of paper in the stack. When the horizontal distance between the blow assembly 3 and the paper stack is close, the blown area of ​​the paper stack is small, and the blowing effect is concentrated, further reducing the adhesion of the top sheets of the stack, thereby reliably separating the top sheets of the stack. Under the suction force of the suction assembly 4, the top sheets of the stack can be reliably distributed, reducing the problem of multiple layers of paper being sucked out simultaneously due to paper adhesion.

[0046] During use, as the paper is gradually distributed, the lifting component 1 gradually raises the bottom of the paper pile, while the limiting component 2 moves horizontally back and forth as the lifting component 1 rises, ensuring that the paper pile always maintains a stable posture. The blowing component 3 moves with the limiting component 2, blowing air on the side of the paper pile to separate the top layer of paper from the paper pile below. The suction component 4 is located at the input end of the conveying component 5. Once the top layer of paper is successfully separated, the suction component 4 can absorb it and send it to the conveying component 5, thereby achieving efficient and continuous paper distribution and transportation. This device can efficiently and stably distribute and transport multiple stacked sheets of paper one by one to the gluing and molding mechanism, improving production efficiency while significantly improving the stability of product quality.

[0047] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the paper separation mechanism includes a support assembly 6, and the lifting assembly 1 and the limiting assembly 2 are both arranged on the support assembly 6. The specific structure of the support assembly 6 is not limited, as long as it can achieve the necessary supporting function.

[0048] There are two groups of lifting components 1, which are arranged at intervals perpendicular to the conveying direction of the paper, which helps to keep the paper pile stable during the rising process and avoid tilting or skewing, thereby ensuring the flatness of the paper pile, so that each piece of paper can be accurately separated and sent to the subsequent process, thereby improving the paper separation accuracy.

[0049] like Figure 1 、 Figure 2 and Figure 3As shown, the lifting assembly 1 includes a lifting drive 11, a screw 12, a nut 13 and a lifting frame 14. The lifting drive 11 is arranged on the support assembly 6, and the output end of the lifting drive 11 is connected to one end of the screw 12 by transmission, and the nut 13 is screwed to the screw 12, so that the entire lifting process is more stable and reliable, reducing the risk of paper damage caused by mechanical vibration and enhancing structural stability. The nuts 13 of the two sets of lifting assemblies 1 are connected by a connecting member 15, and the lifting frame 14 connects the two nuts 13. The lifting frame 14 is used to support the paper pile. The design of the double lifting assembly 1 not only improves the carrying capacity of the paper pile, but also ensures the continuity and consistency of the paper through synchronous action, thereby improving production efficiency; at the same time, the threaded transmission method helps to improve the movement accuracy and is more suitable for the vertical movement of thinner paper.

[0050] When the lift drive 11 is in operation, it drives the lead screw 12 to rotate. Because the nut 13 is threaded onto the lead screw 12 and restrained by the connector 15, the rotation of the lead screw 12 is converted into linear motion of the nut 13. Furthermore, the nuts 13 of the two lift assemblies 1 are connected by the connector 15, which also helps ensure the synchronized linear motion of the two nuts 13. The lift frame 14 connects the two nuts 13 and, driven by the linear motion of the nuts 13, moves up and down accordingly, thereby achieving a smooth lift of the paper stack.

[0051] like Figure 1 、 Figure 2 and Figure 3 As shown, the limiting assembly 2 optionally includes a support member 21, a fixed member 22, an elastic member 23, a pusher 24, and a slide 25. The support member 21 is connected to the support assembly 6, the fixed member 22 is connected to the support member 21, and the slide 25 is located on the side of the fixed member 22 away from the support member 21. The slide 25 is slidably connected to the fixed member 22. The pusher 24 is located between the fixed member 22 and the slide 25. The pusher 24 can push the slide 25 horizontally away from the fixed member 22, so that the slide 25 abuts the side of the paper stack. The two ends of the elastic member 23 are respectively connected to the fixed member 22 and the slide 25. The elastic member 23 is used to horizontally move the slide 25 toward the fixed member 22 to reset.

[0052] The slider 25 can move horizontally under the action of the pusher 24, allowing it to abut the paper stack, thereby horizontally limiting the paper stack. This ensures the neatness of the stack, improves the positioning accuracy of the top sheets of paper in the stack, and reduces the problem of paper deviation causing reduced separation reliability. After the pusher 24 releases its pushing action on the slider 25, the elastic member 23 allows the slider 25 to quickly return away from the side of the paper stack after completing the paper stacking operation. This intermittent push against the paper stack helps maintain the neatness of the paper stack. When the paper stack needs to be horizontally limited, the slider 25 moves outward under the action of the pusher 24, contacting and applying pressure to the side of the paper stack, effectively limiting the paper stack. Furthermore, after completing a paper separation operation, the elastic member 23 quickly pulls the slider 25 back to its original position, ensuring smooth paper separation and minimizing interference. The elastic member 23 can be a spring and can be provided at both ends of the slider 25 to improve the movement stability of the slider 25.

[0053] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the support member 21 includes a rotating portion 211, a supporting portion 212, and a limiting portion 213. The bottom of the supporting portion 212 is connected to the support assembly 6, and the rotating portion 211 is rotatably connected to the supporting portion 212. The paper separation mechanism also includes an adjustment assembly 7, which is disposed on the support assembly 6 and is used to adjust the angle of the rotating portion 211. The limiting portion 213 is connected to one end of the rotating portion 211 and can be positioned relative to the supporting portion 212 via a fastener 26 to fix the angle of the rotating portion 211.

[0054] The adjustment component 7 can flexibly adjust the angle of the rotating part 211 to adapt to different sizes of paper, thereby improving the scope of application and flexibility of the device. The relative positioning design between the limiting part 213 and the supporting part 212 enables the rotating part 211 to be stably maintained after the angle is adjusted, avoiding the angle of the rotating part 211 changing due to vibration or other factors during use, thereby affecting the paper separation effect. The rotating part 211 can rotate around the supporting part 212, and the angle of the rotating part 211 can be adjusted by the adjustment component 7 to ensure that the limiting component 2 maintains a suitable contact position with the side of the paper pile. When a specific angle needs to be fixed, the supporting part 212 can be tightened by fasteners 26 such as bolts, and the limiting part 213 and the supporting part 212 are positioned relative to each other, so that the rotating part 211 is stabilized at the desired angle, ensuring the stability of the paper separation process.

[0055] like Figure 1 、 Figure 2 and Figure 4As shown, optionally, the adjustment assembly 7 includes a telescopic driving member 71 and a push member 72. The fixed end of the telescopic driving member 71 is provided on the support assembly 6, the telescopic end of the telescopic driving member 71 is connected to the first end of the push member 72, and the second end of the push member 72 is used to push the rotating portion 211 away from one end of the limiting portion 213.

[0056] The telescopic drive member 71 provides a stable power output, so that the push member 72 can push the rotating part 211 away from one end of the limiting part 213, thereby adjusting the posture of the sliding member 25 and optimizing the paper distribution effect. When the angle of the rotating part 211 needs to be changed, the telescopic end of the telescopic drive member 71 extends outward, pushing the first end of the push member 72, and then the second end of the push member 72 pushes the rotating part 211 away from one end of the limiting part 213. This action allows the rotating part 211 to rotate around the support part 212, achieving precise adjustment of the position of the sliding member 25. The telescopic drive member 71 can be a structure that can achieve telescopic movement, such as a cylinder, a hydraulic cylinder, or an electric telescopic rod; the push member 72 is in the shape of a 匚, so that the angles of the two limiting components 2 can be adjusted at the same time, so that the setting angles of the two limiting components 2 are the same.

[0057] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the support portion 212 is provided with a rotating rod 214, which is rotatably connected to the rotating portion 211. A torsion spring is provided between the rotating rod 214 and the rotating portion 211 to enable the rotating portion 211 to rotate and reset. The design of providing a torsion spring between the rotating rod 214 and the rotating portion 211 enables the rotating portion 211 to rotate in the opposite direction after the external force of the push member 72 is released, thereby achieving automatic reset and reducing equipment maintenance costs.

[0058] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the limiting assembly 2 and the lifting assembly 1 are arranged in a one-to-one correspondence, so that one lifting assembly 1 can drive one limiting assembly 2 to move, reducing the load of the lifting assembly 1 and improving reliability.

[0059] The pusher 24 of the limiting assembly 2 includes a cam 241, a rotating shaft 242, a first sprocket 243, a chain 244, and a second sprocket 245. The rotating shaft 242 is rotatably connected to the fixed member 22 and vertically limits the rotating shaft 242 through the fixed member 22, thereby supporting the rotating shaft 242. The specific method of the rotational connection between the rotating shaft 242 and the fixed member 22 is not limited. The first sprocket 243 and the cam 241 are both connected to the rotating shaft 242. Under the action of the elastic member 23, the outer peripheral surface of the cam 241 always abuts the sliding member 25. The second sprocket 245 is connected to the lead screw 12. The chain 244 is transmission-connected between the first sprocket 243 and the second sprocket 245, so that the rotation of the lead screw 12 can drive the rotation of the cam 241, and the rotation of the cam 241 drives the sliding member 25 to move horizontally back and forth. It should be noted that the adjustment of the adjustment component 7 is before the paper is distributed, and the length of the chain 244 is determined according to the position of the rotating part 211 after rotation and fixation. An adjustable tensioning wheel can also be provided to make the length of the chain 244 meet the rotation requirements of the rotating part 211.

[0060] like Figure 1 、 Figure 2 and Figure 3 As shown, when the lead screw 12 rotates, the second sprocket 245 rotates accordingly, driving the first sprocket 243 to rotate synchronously via the chain 244, thereby causing the rotating shaft 242 and cam 241 to rotate together. As the cam 241 rotates, its outer circumference constantly abuts the slider 25, pushing the slider 25 away from the fixed member 22, achieving horizontal movement of the slider 25. During this process, the slider 25 overcomes the force of the elastic member 23 and extends outward, completing the position limiting action on the side of the paper stack. When the cam 241 rotates back to the corresponding position, the slider 25 automatically returns to its initial position under the restoring action of the elastic member 23. The coordinated action of the cam 241, the rotating shaft 242, the first sprocket 243, the chain 244 and the second sprocket 245 enables the rotation of the screw 12 to effectively drive the rotation of the cam 241, and then the rotation of the cam 241 intermittently pushes the sliding member 25 to move horizontally away from the fixed member 22, thereby achieving intermittent pushing of the side of the paper pile, so that the paper pile can be sorted after each piece of paper is distributed, which helps to improve the reliability of single-sheet paper distribution.

[0061] like Figure 1 、 Figure 2 and Figure 3As shown, the blow assembly 3 is optionally offset from the side of the slider 25 that abuts the paper stack. This allows the blow assembly 3 to be positioned near the end of the slider 25 closest to the conveyor assembly 5, effectively blowing air toward the edge of the top sheets of paper near the conveyor assembly 5. This effectively reduces paper sticking and improves paper separation efficiency. A groove 251 is provided on the side of the slider 25 that is distal to the fixed member 22. The blow assembly 3 is positioned within the groove 251. The horizontal depth of the groove 251 is greater than the thickness of the blow assembly 3, allowing the blow assembly 3 to be recessed within the slider 25. The groove 251 on the slider 25 forms a channel at the front end of the blow assembly 3 in the blowing direction, thereby reducing the risk of turbulence in the blowing direction when the blow assembly 3 is horizontally far from the paper stack. When the blow assembly 3 is horizontally close to the paper stack, the groove 251 improves the concentration of the blowing action, creating a vertical gap between the top sheets of paper and the underlying paper stack at the end of the paper stack closest to the conveyor assembly 5, ensuring reliable delivery of the top sheets.

[0062] As the slider 25 moves horizontally on the fixed member 22, the air blowing assembly 3 changes position with the slider 25. Because the air blowing assembly 3 is offset toward the end of the slider 25 closest to the conveyor assembly 5 and recessed within the groove 251 on the slider 25, it maintains a certain distance from the sides of the paper stack, preventing damage or jamming of the paper due to direct contact. This design also allows the air blowing assembly 3 to more accurately align with the edge of the topmost sheet of paper in the stack, effectively separating the sheets and improving both efficiency and reliability.

[0063] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the conveying assembly 5 includes a conveying platform 51, a conveying drive 52, a connecting shaft 53 and a conveying roller 54. Along the conveying direction of the paper, the conveying platform 51 is arranged at the rear end of the lifting assembly 1, ensuring that the paper is smoothly transported to the gluing and molding mechanism after being sucked out of the paper pile. The conveying drive 52 is arranged on the conveying platform 51, and the output end of the conveying drive 52 is transmission-connected to the connecting shaft 53, and the conveying roller 54 is connected to the connecting shaft 53, so that the conveying roller 54 on the connecting shaft 53 can operate stably and reliably, and the paper can be clamped and transported between the conveying roller 54 and the conveying platform 51. The transportation of single-layer paper is achieved through the cooperation of the suction assembly 4, the conveying roller 54 and the conveying platform 51, ensuring the continuous transportation of paper to the conveying platform 51.

[0064] When the suction assembly 4 extracts the topmost sheet from the stack, the conveyor drive 52 rotates the conveyor roller 54 via the connecting shaft 53. The conveyor roller 54, in conjunction with the suction assembly 4, smoothly delivers the individual sheets to the conveyor platform 51, ensuring that the sheets do not tilt or jam during transport, thereby improving the stability and efficiency of paper transport. The conveyor drive 52 can be a motor, and the conveyor roller 54 has a rough surface to facilitate the movement of the sheets, ensuring their transport.

[0065] like Figure 1 、 Figure 2 and Figure 3 As shown, the suction assembly 4 includes a suction pump and a suction nozzle 41. The suction pump is mounted on the conveying mechanism. The first end of the suction nozzle 41 is connected to the output of the suction pump. The second end of the suction nozzle 41 is used to suck the paper, allowing it to move from the paper pile to below the conveyor roller 54. The conveyor roller 54 and the conveying platform 51 then move, allowing the single layer of paper to be reliably conveyed onto the conveying platform 51. The suction nozzle 41 can be positioned horizontally or tilted, with the second end of the suction nozzle 41 lower than the first end. This allows the suction of the single layer of paper while minimizing interference with the conveying of the paper. The conveying platform 51 can include a conveyor belt, with baffles 55 vertically spaced above the conveyor belt to reduce the risk of the single layer of paper flying off the conveyor belt. The air blowing assembly 3 can be a fan. The top height of the paper pile matches the conveying platform 51, ensuring that the top layer of paper can be smoothly moved onto the conveying platform 51 by the suction assembly 4 and the conveyor roller 54, allowing it to be conveyed.

[0066] Optionally, the paper separation mechanism further includes two sets of pressing assemblies 8, located on either side of the suction assembly 4. Two sets of conveyor rollers 54 are provided, one on each side of the suction assembly 4 along the paper conveying direction. The pressing assemblies 8 are arranged in a one-to-one correspondence with the conveyor rollers 54. Positioned between the conveyor rollers 54 and the suction assembly 4, the pressing assemblies 8 can vertically limit the paper while keeping them away from the suction assembly 4, minimizing the impact of the vertical limit on the blowing separation of the topmost layer of paper.

[0067] like Figure 1 、 Figure 2 and Figure 3As shown, the pressing assembly 8 includes a vertical telescopic member 81 and a pressing member 82. The fixed end of the vertical telescopic member 81 is connected to the supporting assembly 6, and the telescopic end of the vertical telescopic member 81 is connected to the pressing member 82. The vertical telescopic member 81 drives the pressing member 82 to move vertically, so as to selectively limit the vertical movement distance of the paper by the pressing member 82, and to help the edge of the paper corresponding to the position of the conveying roller 54 to be separated from the paper stack under the blowing action of the blowing assembly 3, so that the paper located below the conveying roller 54 is conveniently taken out onto the conveying assembly 5. The vertical telescopic member 81 drives the pressing member 82 to move vertically to adjust the vertical position of the pressing member 82, so that the pressing member 82 can reliably limit the vertical movement distance of the paper, prevent the paper from being deviated or overlapped due to excessive vertical freedom, and thus ensure the paper to smoothly enter the subsequent process. In the process of the paper being sucked from the suction assembly 4 and sent into the conveying roller 54, the pressing assembly 8 can limit the vertical movement distance of the paper, so as to prevent the paper from flying up due to external interference. When it is necessary to place the paper stack with the distribution, the pressing member 82 can be moved upward, which reduces the operation difficulty. The vertical telescopic member 81 can be a gas cylinder, a hydraulic cylinder or an electric telescopic rod, etc. which can realize telescopic structure.

[0068] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting and control, etc. to enable the device to operate normally; the shape, size, material and setting number of each part of the device can be determined according to the needs, as long as the corresponding functions can be realized.

[0069] The implementation principle of the conical paper sleeve forming device for ice cream cone packaging is that the lifting assembly 1 supports the paper stack and adjusts the position according to the change of the height of the paper stack itself, so that the height of the uppermost paper of the paper stack remains unchanged, so that the uppermost paper of the paper stack is always at a suitable separation height; the limiting assembly 2 moves horizontally reciprocatingly according to the change of the lifting height of the paper stack by the lifting assembly 1, so as to horizontally limit the paper stack, reduce the risk of disorder of the remaining paper of the paper stack caused by the separation of the uppermost paper, improve the positioning accuracy of the paper in the paper stack, and reduce the distribution difficulty of the paper; the suction assembly 4 sucks and sends the separated single paper into the conveying assembly 5, so that the single paper on the uppermost layer of the paper stack can be reliably conveyed to the conveying assembly 5, and the continuous supply of the paper is ensured; the single-layer paper is conveyed to the gluing forming mechanism by the conveying assembly 5, and the gluing forming mechanism is closely matched with the conveying assembly 5, so that each paper can be accurately treated by gluing, and finally formed into a conical paper sleeve.

[0070] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
