Description

Technical Field

[0001] This utility model relates to the field of file box production and processing, and in particular to a flattening device for file box production and processing. Background Technology

[0002] The flattening device for file box production and processing is a mechanical device used to flatten file box blanks. It usually consists of a frame, a liftable pressure plate (hydraulic or pneumatic driven) and a control system. Its working principle is to flatten the folded cardboard or plastic material of the file box by applying pressure, eliminating wrinkles and warping, and ensuring that the surface of the finished product is flat.

[0003] When flattening cardboard or plastic materials for file boxes, the flattening is usually achieved by applying downward pressure. This is done by squeezing in one direction. The degree of flattening differs between the top and bottom sides, resulting in different flattening effects. At the same time, excessive squeezing pressure during the squeezing process can cause the cardboard or plastic materials for file boxes to crack, affecting production. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a flattening device for the production and processing of file boxes, thereby improving the flattening effect of the device and enhancing its protective effect on the cardboard of the file boxes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flattening device for manufacturing and processing file boxes includes a support frame for support, a lower pressure plate slidably connected inside the support frame, a lower pressure push rod fixedly connected to the top of the support frame, the output end of the lower pressure push rod fixedly connected to the top of the lower pressure plate, an extrusion plate disposed directly below the lower pressure plate, an adjusting lower pressure component installed inside the lower pressure plate to control the lower pressure force, multiple support sleeves fixedly connected to the bottom of the support frame, a support plate fixedly connected to the top of the support sleeves, a placement plate abutting the top of the support plate, blocking plates fixedly connected to both sides of the top of the placement plate, and a flipping and lifting component installed inside the support plate to achieve simultaneous pressure from above and below to improve the flattening effect.

[0007] Furthermore, the adjusting pressing assembly includes multiple mounting slide rods that slide inside the pressing plate. The bottom ends of the mounting slide rods are respectively fixedly connected to the top ends of the extrusion plate. The bottom end of the pressing plate is connected to the top end of the extrusion plate through multiple pressing springs. An upward connecting frame is fixedly connected to the top end of the mounting slide rods.

[0008] Furthermore, the flipping and lifting assembly includes rotating rollers located on both sides of the support plate, with an lifting and flipping plate fixedly connected to the inner side of the rotating rollers, and multiple toothed blocks fixedly connected to the outer side of the rotating rollers. Flipping toothed plates are fixedly connected to both sides of the bottom end of the lower pressure plate, and the inner side of the flipping toothed plates meshes with the toothed blocks.

[0009] Furthermore, the bottom end of the placement plate is fixedly connected with multiple lifting limiting rods, and the two sides of the support plate are provided with mounting slots. The outer side of each lifting limiting rod passes through the inside of the mounting slot and is slidably connected to the inside of the support sleeve.

[0010] Furthermore, multiple limiting rods are fixedly connected to both sides of the top of the lower pressure plate, and the external of the limiting rods are slidably connected to both sides of the top of the support frame.

[0011] Furthermore, both sides of the bottom end of the placement plate are fixedly connected with bottom soft rubber pads, and the top of the lifting and flipping plate is attached to the bottom end of the bottom soft rubber pads.

[0012] Furthermore, a reset switch is fixedly connected to the top left side of the lower pressure plate, and a toggle plate is rotatably connected inside the reset switch.

[0013] Furthermore, the reset switch is electrically connected to the push rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the downward pressure is generated on the lower pressure plate by the downward push rod, and the flipping tooth plate is also pressed down. The flipping tooth plate meshes with the tooth block, thereby flipping the upper flipping plate to the upper side, thereby generating an upward pushing force on the placement plate. At the same time, the cardboard of the file box is squeezed from both sides, improving the flattening effect of the device.

[0016] 2. In this utility model, the squeezing force generated by the lower pressure plate and the placement plate simultaneously inward will cause the lower pressure spring to retract, pushing the upper connecting frame upward. As the upper connecting frame moves upward, it will move the toggle plate, and the reset switch will send a retraction signal to the limit rod, thereby completing the flattening of the file box cardboard and improving the protective effect of the device on the flattening of the file box cardboard.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a flattening device for the production and processing of file boxes, including a support frame 1 for support, a lower pressure plate 2 slidably connected inside the support frame 1, a lower pressure push rod 3 fixedly connected to the top of the support frame 1, the output end of the lower pressure push rod 3 fixedly connected to the top of the lower pressure plate 2, an extrusion plate 10 arranged directly below the lower pressure plate 2, an adjusting lower pressure component installed inside the lower pressure plate 2 to control the lower pressure force, multiple support sleeves 15 fixedly connected to the bottom of the support frame 1, a support plate 14 fixedly connected to the top of the support sleeves 15, a placement plate 13 attached to the top of the support plate 14, and blocking plates 12 fixedly connected to both sides of the top of the placement plate 13. A flip-up lifting component is installed on the inner side of the support plate 14 to achieve simultaneous pressure from above and below to improve the flattening effect. The assembly includes rotating rollers 18 located on both sides of the support plate 14, with an upward flipping plate 17 fixedly connected to the inner side of the rotating rollers 18 and multiple toothed blocks 19 fixedly connected to the outer side of the rotating rollers 18. Flipping toothed plates 9 are fixedly connected to both sides of the bottom end of the lower pressure plate 2, and the inner side of the flipping toothed plates 9 meshes with the toothed blocks 19. Multiple upward limiting rods 21 are fixedly connected to the bottom end of the placement plate 13. Mounting slots 16 are provided on both sides of the support plate 14. The outer side of the upward limiting rods 21 passes through the interior of the mounting slots 16 and is slidably connected to the interior of the support sleeve 15. Multiple limiting rods 7 are fixedly connected to both sides of the top end of the lower pressure plate 2, and the outer side of the limiting rods 7 is slidably connected to both sides of the top end of the support frame 1. Bottom soft rubber pads 20 are fixedly connected to both sides of the bottom end of the placement plate 13, and the top end of the upward flipping plate 17 is attached to the bottom end of the bottom soft rubber pad 20.

[0025] Place the cardboard box to be processed on the top of the placement plate 13. At this time, activate the downward push rod 3 to generate a downward pushing force on the downward pressure plate 2. As the downward pressure plate 2 moves down, the flipping toothed plate 9 and the pressing plate 10 move down simultaneously. The flipping toothed plate 9 engages with the toothed block 19 downward, thereby rotating the rotating roller 18. The upward flipping plate 17 is subjected to force and flips upward. The bottom end of the upward flipping plate 17 contacts the bottom end of the bottom soft rubber pad 20, thereby generating an upward pushing force on the placement plate 13. The pressing plate 10 and the placement plate 13 simultaneously exert a squeezing force on the cardboard box, thereby improving the flattening effect of the device.

[0026] Reference Figure 1 and Figure 3 The adjusting pressing assembly includes multiple mounting slide rods 11 that slide inside the pressing plate 2. The bottom ends of the mounting slide rods 11 are respectively fixedly connected to the top end of the extrusion plate 10. The bottom end of the pressing plate 2 is connected to the top end of the extrusion plate 10 through multiple pressing springs 8. The top end of the mounting slide rods 11 is fixedly connected to an upward connecting frame 4. The left side of the top end of the pressing plate 2 is fixedly connected to a reset switch 6. The reset switch 6 is rotatably connected to a toggle plate 5. The reset switch 6 is electrically connected to the pressing push rod 3.

[0027] During the flattening process, when the extrusion plate 10 exerts pressure on the cardboard of the file box, the pressure force generated by the lower pressure plate 2 and the placement plate 13 inward will cause the lower pressure spring 8 to retract. The multiple mounting slides 11 on the top of the extrusion plate 10 will move upward, thereby pushing the lifting connecting frame 4 upward. As the lifting connecting frame 4 moves upward, it contacts the toggle plate 5, thereby moving the toggle plate 5. The reset switch 6 sends a retraction signal to the limit rod 7, thereby retracting the lower pressure plate 2 upward. The lower pressure plate 2 and the placement plate 13 unfold, thus completing the flattening of the cardboard of the file box and improving the protective effect of the device on the flattening of the cardboard of the file box.

[0028] Working principle: The cardboard for the file box to be processed is placed on top of the placement plate 13. At this time, the downward push rod 3 is activated, generating a downward pushing force on the downward pressure plate 2. As the downward pressure plate 2 moves downward, the flipping toothed plate 9 and the pressing plate 10 move downward simultaneously. The flipping toothed plate 9 engages with the toothed block 19 downward, thereby rotating the rotating roller 18. The upward flipping plate 17 is subjected to force and flips upward. The bottom end of the upward flipping plate 17 contacts the bottom end of the bottom soft rubber pad 20, thereby generating an upward pushing force on the placement plate 13. The pressing plate 10 and the placement plate 13 simultaneously exert a squeezing force on the cardboard for the file box, thereby improving the flattening effect of the device. During the flattening process, when the extrusion plate 10 exerts pressure on the cardboard of the file box, the pressure force generated by the lower pressure plate 2 and the placement plate 13 inward will cause the lower pressure spring 8 to retract. The multiple mounting slides 11 on the top of the extrusion plate 10 will move upward, thereby pushing the lifting connecting frame 4 upward. As the lifting connecting frame 4 moves upward, it contacts the toggle plate 5, thereby moving the toggle plate 5. The reset switch 6 sends a retraction signal to the limit rod 7, thereby retracting the lower pressure plate 2 upward. The lower pressure plate 2 and the placement plate 13 unfold, thus completing the flattening of the cardboard of the file box and improving the protective effect of the device on the flattening of the cardboard of the file box.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
