Description

Technical Field

[0001] This utility model relates to a window patching machine, and more particularly to a film feeding device for a non-standard window patching machine. Background Technology

[0002] Irregular window pasting machines need to crimp and punch the film strip before cutting it into film sheets that are then pasted onto the window openings of the paper. The creases created by crimping guide the folding of the film sheet. Punching can not only produce film sheets of specific shapes, but also punch holes at both ends of the creases to prevent the film sheet from arching during folding. However, punching reduces the surface area of ​​the film strip, causing tension imbalance. Furthermore, since film strip traction is an intermittent action, the film strip will undergo significant deformation due to tension imbalance at high speeds, resulting in inaccurate crimping and punching positions. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a film feeding device for a non-standard window patching machine, which is designed with a transition roller group to press the film belt to ensure accurate pressing line position.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The film feeding device of this irregular window patching machine includes an unwinding assembly and a traction assembly. The traction assembly and the unwinding assembly cooperate to form a film feeding path. A creasing assembly and a punching assembly are sequentially arranged on the film feeding path. The film feeding direction is from front to back. There are at least three sets of punching assemblies. The traction assembly includes a transition roller group. The transition roller group includes a pressure roller and a transition roller that cooperate with each other. On the film feeding path, the transition roller group is located after the creasing assembly. On the film feeding path, at least two sets of punching assemblies are located after the transition roller group.

[0005] In this scheme, the two sets of punching components are located after the transition roller group, so that the tension imbalance generated by punching will not be transmitted to the film belt at the crimping component. Moreover, the transition roller group will suppress the jumping during the film feeding process and avoid inaccurate punching position.

[0006] Preferably, the traction assembly includes a traction roller group and a suction roller, and a cutting assembly is provided between the traction roller group and the suction roller.

[0007] In this scheme, the suction roller adsorbs the end of the membrane belt and then the cutting component cuts the membrane belt to form a membrane sheet.

[0008] Preferably, the pressing assembly consists of two sets, the punching assembly consists of three sets, the film feeding path is provided with a longitudinal punching station, a transverse punching station and a corner cutting station in sequence corresponding to the punching assembly, the film feeding path is provided with a longitudinal pressing station and a transverse pressing station in sequence corresponding to the pressing assembly, and the transition roller group is located between the longitudinal punching station and the transverse punching station.

[0009] In this solution, the longitudinal punching and the transverse punching correspond to the longitudinal pressure line and the transverse pressure line, respectively. At the corner cutting station, a corner of the diaphragm is cut off based on the two punching points. The punching is carried out in three stations. It can be compatible with production needs such as single longitudinal punching and single transverse punching through program control or disassembly and assembly.

[0010] Preferably, the transition roller group is arranged between the mounting plates, and the mounting plates are further provided with an adjustment component and a punching component corresponding to the longitudinal punching station. The adjustment component includes a rotating shaft and a gear. The rotating shaft is connected to a handwheel. The gear is arranged on the rotating shaft and meshes with a rack. The rack is arranged longitudinally on the frame. The frame is provided with an adjustment guide rail. The mounting plate is connected to an adjustment slider that slides in cooperation with the adjustment guide rail.

[0011] In this scheme, rotating the handwheel drives the rotating shaft and gear to rotate. The gear moves longitudinally along the rack, causing the mounting plate to be adjusted longitudinally to adapt to the differences in the punching position of diaphragms of different specifications. The adjusting slider and adjusting guide rail work together to guide the longitudinal movement of the mounting plate.

[0012] Preferably, an adjusting screw is provided between the mounting plates, and the punching assembly is connected to a nut that is threadedly engaged with the adjusting screw.

[0013] In this scheme, rotating the adjusting screw drives the nut to move laterally, adjusting the lateral position of the punching assembly to adapt to the differences in punching position of diaphragms of different specifications.

[0014] Preferably, both the pressure roller and the transition roller are rubber rollers, the pressure roller is rotatably mounted on the mounting base, the mounting base is oscillatingly mounted on the mounting plate, and an elastic element is provided between the mounting base and the mounting plate.

[0015] In this design, the pressure roller can float to adapt to film belts of different thicknesses, the rubber roller makes full contact with the film belt, and the elastic element ensures the pressure provided by the pressure roller, so that the film belt is subjected to sufficient friction.

[0016] Preferably, the mounting plate is equipped with a drive motor, the output end of the drive motor is connected to a drive wheel, the transition roller is connected to a driven wheel, a synchronous belt is wound between the drive wheel and the driven wheel, and the transition roller operates intermittently.

[0017] In this scheme, the drive motor drives the driving wheel, which in turn drives the driven wheel to rotate via a synchronous belt, thus causing the transition roller to rotate.

[0018] Preferably, the pressing assembly includes a pressing roller and a pressing die that cooperate with each other. The pressing roller moves laterally and is positioned above the pressing die. The pressing roller has a groove corresponding to the pressing die.

[0019] In this scheme, the pressure roller descends to bring the film strip into contact with the creasing die, and the creasing die presses the film strip into the groove to complete the creasing.

[0020] Preferably, the punching assembly includes a die base and a punch that moves up and down. The die base has an opening for the film strip to pass through and a cylinder for driving the punch. The upper wall of the opening has a through hole for the punch to pass through, and the lower wall of the opening has a cutting groove that mates with the punch.

[0021] In this scheme, the punch descends and cooperates with the grooving to punch holes or edges on the membrane strip.

[0022] The beneficial effects of this invention are that the two sets of punching components are located after the transition roller group, which can effectively block the transmission of deformation, resulting in less deformation caused by the transverse punching. Furthermore, the transition roller group, positioned after the transverse punching, ensures that the film belt on both sides of the transition roller group can be tensioned. Therefore, this invention has substantial features and advancements compared to the prior art. Attached Figure Description

[0035] See appendix Figure 1-7 In this embodiment, a film feeding device for a non-standard window patching machine includes an unwinding assembly 1 and a traction assembly 2. The traction assembly 2 and the unwinding assembly 1 cooperate to form a film feeding path. A pressure assembly 3 and a punching assembly 4 are sequentially arranged on the film feeding path. The film feeding direction is from front to back.

[0036] The pressure-pressing assembly 3 consists of two sets, the punching assembly 4 consists of three sets, the traction assembly 2 includes a transition roller group 5, a traction roller group 8, and a suction roller 9, with a cutting assembly 10 between the traction roller group 8 and the suction roller 9. The transition roller group 5 includes a pressure roller 6 and a transition roller 7 that cooperate with each other. Both the pressure roller 6 and the transition roller 7 are rubber rollers. The pressure roller 6 is rotatably mounted on the mounting base 20, and the mounting base 20 is oscillatingly mounted on the mounting plate 11. The mounting base 20 and the mounting plate 11 are equipped with... The device has an elastic component. The mounting plate 11 is equipped with a drive motor. The output end of the drive motor is connected to a drive wheel. The transition roller 7 is connected to a driven wheel. A synchronous belt is wound between the drive wheel and the driven wheel. The transition roller 7 operates intermittently. The film feeding path is provided with a longitudinal punching station, a transverse punching station and a corner cutting station in sequence corresponding to the punching assembly 4. The film feeding path is provided with a longitudinal pressing station and a transverse pressing station in sequence corresponding to the pressing assembly 3. The transition roller group 5 is located between the longitudinal punching station and the transverse punching station.

[0037] In this embodiment, the traction component 2 conveys the film strip pulled out by the unwinding component 1 backward. The film strip passes through the longitudinal pressing station, the transverse pressing station, the longitudinal punching station, the transverse punching station and the corner cutting station in sequence to complete the pressing of crease lines, the punching of the two ends of the crease lines and the cutting of one corner of the film. When the end of the film strip is attracted and pulled by the suction roller 9, the cutting component 10 cuts the film strip to form a new end of the film strip. The part of the film strip attracted by the suction roller 9 forms a film.

[0038] The unwinding assembly 1 includes an unwinding shaft and a film storage roller group for controlling tension. The traction roller group 8 includes a driving roller and a driven roller that cooperate with each other. The suction roller 9 has suction holes on its surface for forming an adsorbed film strip. The cutting assembly 10 includes a cutter that moves up and down and a support plate that cooperates with it. All of these are mature technologies. A set of creasing assemblies 3 corresponds to a crease line, and a set of punching assemblies 4 corresponds to punching holes at both ends of a crease line or a punching hole position. The number is not limited to the one in this embodiment and can be adjusted according to the specific film design. In this embodiment, the film strip breaks laterally when punching holes and cutting corners. The deformation caused by the change in tension is large. The transition roller group 5 is set in front of these two stations and can effectively block the transmission of deformation. The deformation caused by punching holes is small. The transition roller group 5 is set after the punching holes so that the film strip on both sides of the transition roller group 5 can be tensioned.

[0039] In other alternative implementations, the overall punching work can be completed in one or two stations by merging the punching dies. Two sets of punching components can be merged into one and are also considered as two sets. The punching hole positions remain unchanged. The number of punching components can also be increased at a single station to complete two corner cuts or form more diverse films.

[0040] See appendix Figure 3-5 The transition roller group 5 is arranged between the mounting plates 11. The mounting plates 11 are also provided with an adjustment component 12 and a punching component 4 corresponding to the longitudinal punching station. The adjustment component 12 includes a rotating shaft 13 and a gear 14. The rotating shaft 13 is connected to a handwheel 15. The gear 14 is arranged on the rotating shaft 13 and meshes with a rack 16. The rack 16 is arranged longitudinally on the frame 17. The frame 17 is provided with an adjustment guide rail 18. The mounting plates 11 are connected with an adjustment slider that slides with the adjustment guide rail 18. An adjustment screw is provided between the mounting plates 11. The punching component 4 is connected with a nut that threads with the adjustment screw.

[0041] In this embodiment, when the diaphragm specifications change, rotating the handwheel 15 drives the rotating shaft 13 to rotate. The longitudinal position of the transition roller group 5 and the punching assembly 4 is adjusted by the meshing of the gear 14 and the rack 16. The longitudinal adjustment of the other punching assembly 4 and the pressing assembly 3 is the same. The adjusting screw is also connected to the handwheel 15. Rotating the handwheel 15 drives the adjusting screw to rotate. The nut (not specifically shown in the figure) drives the punching assembly 4 to perform lateral adjustment. The other punching assembly 4 is the same.

[0042] See appendix Figure 2 , 6 The pressing assembly 3 includes a pressing roller 21 and a pressing die 22 that cooperate with each other. The pressing roller 21 moves laterally and is raised and lowered above the pressing die 22. The pressing roller 21 has a groove corresponding to the pressing die 22. The punching assembly 4 includes a die base 25 and a punch that moves up and down. The die base 25 has an opening for the film strip to pass through and a cylinder 26 for driving the punch. The upper wall of the opening has a through hole for the punch to pass through, and the lower wall of the opening has a cutting groove that cooperates with the punch.

[0043] In this embodiment, the pressing is divided into horizontal pressing and vertical pressing, both of which are mature technologies. During horizontal pressing, the pressing roller 21 descends to make the film belt contact the pressing die 22. The pressing die 22 presses the film belt into the groove. The pressing roller 21 moves laterally to form a horizontal crease line. During punching, the punch descends and cooperates with the cutting groove to punch out the corresponding hole on the film belt. This is a mature technology. The lateral movement of the pressing roller 21 is driven by a motor, and the synchronous belt and synchronous pulley drive the transmission. The moving seat where the pressing roller 21 is located is set on the synchronous belt.

[0044] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
