Description

Technical Field

[0001] The present invention relates to the technical field of thin film processing and punching devices, and more specifically, to an on-line punching device for heat shrinkable films used in cigarettes. Background Art

[0002] Heat shrinkable films are used for the sales and transportation of various products. Their main functions are to stabilize, cover, and protect products. The shrinkable film must have high puncture resistance, good shrinkability, and certain shrink stress. By using heat shrinkable films to package products externally, scattered small pieces can be tightly and fixedly bundled into a unit, and at the same time, a very light protective outer surface can be formed around the products, thereby achieving the purposes of dust prevention, oil prevention, moisture prevention, waterproofing, and anti-theft.

[0003] However, due to the shrinkability and certain shrink stress of the heat shrinkable film itself, during the process of punching the film by the device, it is very easy to have processing deviations, it is not easy to fix when punching the heat shrinkable film, and due to its own shrink stress, the inner wall of the hole is very uneven when punching, and it is also possible that the scraps at the corners during punching remain in the hole, resulting in poor punching effect.

[0004] Moreover, after the heat shrinkable film is punched, the waste generated by punching is very easy to remain on the device, which is very inconvenient for the staff to clean it, and it is very easy to cause poor punching effect of the subsequent heat shrinkable film due to the waste. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an on-line punching device for heat shrinkable films used in cigarettes. By implementing die change processing in a simple way when punching the heat shrinkable film, the adaptability of the device is increased, the deformation of the heat shrinkable film during punching can be effectively avoided, the punching effect is increased. At the same time, the heat shrinkable film is cut by the pressure when being pressed by the punched thin cylinder, ensuring that the cut surface during punching is neat. At the same time, the waste generated by punching can also be cleaned, which is convenient to use and has good practicability, so as to solve the problems raised in the above background art.

[0022] When the mounting frame and the punching thin cylinder member press down for punching, the punching thin cylinder member can cover the top of the conical ejector rod. When the punching thin cylinder member covers the top of the conical ejector rod, the inner wall of the ring cutting piece will contact the outer side of the conical ejector rod, so that the heat shrinkable film between the conical ejector rod and the punching thin cylinder member can be cut by the pressure when the punching thin cylinder member presses down. At the same time, the air pump extracts the air flow in the mounting frame, the flow collecting hopper and the punching thin cylinder member, thereby realizing the function of cleaning the waste generated by punching;

Detailed Embodiment

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As shown in the attached Figure 1-6 The on-line punching device for cigarette heat shrinkable film shown includes a base 1, and two first support plates 2 are provided on the top of the base 1. An elastic positioning punching mechanism is provided between the two first support plates 2;

[0033] The elastic positioning punching mechanism includes a turntable 3 provided between the two first support plates 2 and movably connected to the first support plates 2 through a pin. An installation seat 4 is provided between the two turntables 3. A plurality of conical ejector rods 5 for supporting the heat shrinkable film are circumferentially distributed on the surface of the installation seat 4 along the center point of the turntable 3;

[0034] A second support plate 6 is provided on the top of the installation seat 4, and a plurality of transition holes 7 are penetrated through the surface of the second support plate 6;

[0035] A mounting frame 8 is provided on the top of the second support plate 6. A plurality of perforated thin cylinders 9 are provided at the bottom of the mounting frame 8. Ring cutting pieces 22 for punching the heat shrinkable film are provided on the inner walls of the plurality of perforated thin cylinders 9;

[0036] The top of the mounting frame 8 is provided with a flow collector 10 that communicates with the mounting frame 8.

[0037] Refer to the appendix Figure 2 、 3 As shown, on the opposite sides of the two first support plates 2, sliding grooves 11 are respectively formed. In both of the two sliding grooves 11, there is a slider 15 that matches the sliding groove 11 and is slidably connected to the sliding groove 11, and the slider 15 is installed on the second support plate 6. The cross-sectional shapes of the slider 15 and the sliding groove 11 are both set to be T-shaped. The corresponding cooperation of the sliding groove 11 and the slider 15 can play a role in guiding and limiting the movement of the second support plate 6, increasing the stability when the second support plate 6 is displaced. Moreover, since the cross-sectional shapes of the slider 15 and the sliding groove 11 are both set to be T-shaped, the stability when the slider 15 is displaced is increased, further increasing the stability when the second support plate 6 is displaced.

[0038] Refer to the appendix Figure 1 、 2 As shown in FIGS. 2 and 3, a gear box 12 is provided on the top of the first support plate 2. At the bottom of the gear box 12, there are two hydraulic drive components 13 for driving the flow collector 10 and the mounting frame 8 to displace. The gear box 12 can play a supporting role, facilitating the installation of the hydraulic drive components 13 by the staff. At the same time, when the output end of the hydraulic drive component 13 extends, it will drive the flow collector 10 to displace downward, and then the mounting frame 8 will drive the punching thin tube member 9 to displace downward, and the heat shrinkable film is punched by the ring cutter 22.

[0039] Refer to the appendix Figure 2 、 3 As shown in FIGS. 4 and 5, an air pump 14 is provided on one side of the surface of the flow collector 10. One end of the air pump 14 is provided with an extraction pipe 23 that communicates with the flow collector 10 and is used to extract the air flow inside the flow collector 10. The cross-sectional shape of the flow collector 10 is set to be trapezoidal. When the air pump 14 is started, the air flow inside the flow collector 10 will be extracted through the extraction pipe 23. At the same time, since the cross-sectional shape of the flow collector 10 is set to be trapezoidal, the air flow inside the flow collector 10 can be gathered through the trapezoidal inner wall cross-section of the flow collector 10, avoiding the leakage of the air flow and increasing the suction force when the air pump 14 extracts the air flow.

[0040] Refer to the appendix Figure 1 、 2As shown in FIGS. 3 and 6, a first drive motor 17 is provided at one end of the surface of the gearbox 12. A rotating shaft 18 is movably connected to the output end of the first drive motor 17 and is located inside the gearbox 12. Two first gears 19 are provided on the surface of the rotating shaft 18. At the bottom of each of the two first gears 19, a second gear 20 meshing with the first gear 19 is provided. At the bottom of each of the two second gears 20, a lead screw 16 threadedly connected to the slider 15 and used to drive the displacement of the slider 15 is provided. When the first drive motor 17 is started, it will drive the rotation of the rotating shaft 18, and when the rotating shaft 18 rotates, it will drive the rotation of the first gear 19. Since the second gear 20 meshes with the first gear 19, the second gear 20 is caused to rotate, and the lead screw 16 is driven to rotate. And since the lead screw 16 is threadedly connected to the slider 15, the slider 15 can be displaced through the pitch on the surface of the lead screw 16, which is convenient for use.

[0041] Refer to the attached Figure 1 、 2 As shown in FIGS. 3, 4 and 5, a plurality of conical ejector rods 5, transition holes 7 and punching thin tube members 9 correspond to each other, and the plurality of conical ejector rods 5, transition holes 7 and punching thin tube members 9 are respectively on the same vertical plane. The conical ejector rods 5, transition holes 7 and punching thin tube members 9 being on the same vertical plane enables the conical ejector rods 5, transition holes 7 and punching thin tube members 9 to punch the heat shrinkable film when they approach each other, enhancing the effect of punching the heat shrinkable film.

[0042] Refer to the attached Figure 1 、 2 As shown in FIGS. 3, 4 and 5, the top diameter of the conical ejector rod 5 is smaller than the bottom diameter of the conical ejector rod 5, the top diameter of the transition hole 7 is smaller than the bottom diameter of the transition hole 7, and the bottom diameter of the punching thin tube member 9 is larger than the top diameter of the punching thin tube member 9. Electroplated layers are provided on the surface of the conical ejector rod 5 and the inner walls of the transition hole 7 and the punching thin tube member 9. The top diameter of the conical ejector rod 5 being smaller than the bottom diameter of the conical ejector rod 5 enables the conical ejector rod 5 to present a conical shape. With the top diameter of the transition hole 7 being smaller than the bottom diameter of the transition hole 7, the second support plate 6 can be stuck on the conical ejector rod 5 through the transition hole 7. At the same time, when the top end of the conical ejector rod 5 extends from the transition hole 7 and moves downward through the punching thin tube member 9 under pressure, the inner wall of the punching thin tube member 9 and the annular cutting piece 22 punch the heat shrinkable film, improving the efficiency and quality of punching the material.

[0043] Refer to the attached Figure 1 、 2 As shown in FIGS. 4, a second drive motor 21 for driving the rotation of the turntable 3 is provided on one side of the surface of the first support plate 2. The manifold 10, the mounting frame 8 and the punching thin tube member 9 are in communication with each other. When the second drive motor 21 is started, the turntable 3 can be driven to drive the mounting seat 4 to rotate, so that different conical ejector rods 5 on the outside of the mounting seat 4 are located at the bottom of the second support plate 6, facilitating die change.

[0044] See attached Figure 1 , 2 As shown in , 3, 4, and 5, the mounting seat 4 is arranged in a polygonal shape, and the top diameters of the conical top rods 5 belonging to each outer side are arranged in sequence from small to large. The mounting seat 4 is arranged in a polygonal shape, and the conical top rods 5 of different sizes are installed by utilizing the unique polygonal cross-sectional shape of the polygon, which facilitates the punching of holes of different sizes on the heat shrink film and increases the adaptability of the device.

[0045] Working principle of the present invention: First, the staff installs the device made by the invention at the designated position. When punching holes in the heat shrink film, the second driving motor 21 is first started to drive the turntable 3 to drive the mounting seat 4 to rotate, and then the conical top rods 5 of different sizes on the outer cross section of the mounting seat 4 can be moved to the bottom of the second support plate 6. Then, the first driving motor 17 is started to drive the rotating shaft 18 to rotate, and then the first gear 19 drives the second gear 20 to rotate, and the slider 15 moves downward along the pitch of the screw rod 16, so that the second support plate 6 moves downward;

[0046] During the downward displacement of the conical push rod 5, the interference between the conical push rod 5 and the second support plate 6 will be staggered through the transition hole 7, and at the same time, one end of the conical push rod 5 can pass through the second support plate 6 through the transition hole 7 and extend to the top of the second support plate 6. Then, the heat shrink film to be punched is placed on the second support plate 6, and the heat shrink film is supported through the transition hole 7, so that there is a certain distance between the heat shrink film and the second support plate 6 through the conical push rod 5.

[0047] Then, the hydraulic drive assembly 13 is started to drive the collecting bucket 10 to drive the mounting frame 8 and the perforated thin cylinder 9 to move downward, so that the perforated thin cylinder 9 can cover the top of the conical top rod 5. When the perforated thin cylinder 9 covers the top of the conical top rod 5, the inner wall of the ring slice 22 will contact the outer side of the conical top rod 5, so that the heat shrink film between the conical top rod 5 and the perforated thin cylinder 9 can be cut by the pressure when the perforated thin cylinder 9 is pressed down.

[0048] During the process of cutting the heat shrink film, the perforated thin tube 9 is started by the air pump 14, and the airflow inside the collecting bucket 10 is extracted through the extraction pipe 23. During the extraction process, the airflow inside the collecting bucket 10 is extracted into the installation frame 8 through the perforated thin tube 9, the installation frame 8 and the collecting bucket 10 are connected, thereby realizing the function of cleaning the waste generated by punching.
