Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard compaction technology, and in particular to a cardboard compaction device for preventing edge curling. Background Technology
[0002] Anti-warping cardboard compaction device is a device used to apply pressure to cardboard (including single-layer cardboard, corrugated cardboard, hard cardboard, etc.) to keep it flat and compact. It is widely used in cardboard production, printing, packaging and other processes. Its core function is to eliminate defects such as wrinkles, warping, and fluffiness of cardboard through mechanical force, thereby improving the flatness, structural strength and adaptability of cardboard for subsequent processing.
[0003] In existing technologies, conventional anti-warping cardboard compaction devices typically use a large-sized pressure plate to apply pressure to the cardboard, thereby preventing the cardboard from warping. However, these devices only consist of a worktable, pressure plate, and cylinder, without any structure to limit the movement of the cardboard being compacted. While this may not be a significant issue when compacting a single cardboard, it can lead to problems such as the stacked cardboard tilting and shifting when compacting multiple stacked cardboards simultaneously. This affects the compaction effect and prevents the cardboard from effectively preventing warping. Utility Model Content
[0004] In view of this, the present invention provides a cardboard compaction device to prevent warping. The main technical problem to be solved is that conventional cardboard compaction devices do not have a limiting structure for the cardboard, which leads to the problem that the stacked cardboard is prone to tipping or displacement when compacting multiple stacked cardboards.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cardboard compaction device for preventing edge warping, comprising a workbench, wherein a lateral limiting mechanism and a longitudinal limiting mechanism are installed inside the workbench, four legs and two support plates are fixedly connected to the lower surface of the workbench, the lateral limiting mechanism includes a motor, the main body of which is fixedly connected to the outer wall of the support plate, and a bidirectional lead screw is fixedly connected to the output end of the motor, which is rotatably connected to the outer wall of the support plate, and two sets of symmetrically arranged lateral limiting components are threadedly connected to the outer wall of the bidirectional lead screw, both sets of lateral limiting components being slidably connected inside the workbench, each lateral limiting component including a support base, which is threadedly connected to the outer wall of the bidirectional lead screw. The support base is slidably connected to the inside of the worktable. The longitudinal limiting mechanism includes a second motor, the main body of which is fixedly connected to the outer wall of the worktable. The output end of the second motor is fixedly connected to a second bidirectional lead screw, which is rotatably connected to the inside of the worktable. The outer wall of the second bidirectional lead screw is threaded with two sets of symmetrically arranged longitudinal limiting components, both of which are slidably connected to the inside of the worktable. Each longitudinal limiting component includes a second support base, which is threadedly connected to the outer wall of the second bidirectional lead screw and slidably connected to the inside of the worktable. The transverse limiting component also includes a first limiting rod, and the longitudinal limiting component also includes a second limiting rod. Both the first and second limiting rods are slidably connected to the inside of the worktable.
[0006] By adopting the above technical solution, after the stacked cardboard is placed on the workbench, motor one and motor two are started respectively. Motor one drives the bidirectional lead screw one to rotate, causing the two support seats one to slide in the center, which in turn causes the two limit rods one to slide in the center inside the workbench, clamping and limiting the horizontal sides of the stacked cardboard. Motor two drives the bidirectional lead screw two to rotate and causes the two support seats two to slide in the center, which in turn causes the two limit rods two to slide in the center inside the workbench, clamping and limiting the vertical sides of the stacked cardboard. Thus, during the cardboard compaction process, the horizontal and vertical sides of the stacked cardboard are limited, preventing the stacked cardboard from tipping over or shifting.
[0007] As a further description of the above technical solution: the lateral limiting component also includes a housing, which is fixedly connected to the upper surface of the support base and slidably connected to the inside of the worktable, and the limiting rod is slidably connected to the inside of the housing.
[0008] By adopting the above technical solution, during the movement of the support base, the outer shell and the limiting rod slide within the worktable.
[0009] As a further description of the above technical solution: a spring is provided inside the outer shell, one end of the spring is fixedly connected to the lower surface of the limiting rod, and the other end of the spring is fixedly connected to the inside of the outer shell.
[0010] By adopting the above technical solution, the spring supports the limiting rod, which facilitates the subsequent compaction work.
[0011] As a further description of the above technical solution: the longitudinal limiting component also includes a second outer shell, which is fixedly connected to the upper surface of the second support base, and is slidably connected to the inside of the worktable, and the second limiting rod is slidably connected to the inside of the second outer shell.
[0012] By adopting the above technical solution, during the movement of the second support base, the second outer shell and the second limiting rod are also driven to slide within the worktable.
[0013] As a further description of the above technical solution: a spring is provided inside the outer shell 2, one end of the spring 2 is fixedly connected to the lower surface of the limiting rod 2, and the other end of the spring 2 is fixedly connected to the inside of the outer shell 2.
[0014] By adopting the above technical solution, the second spring supports the second limiting rod, which assists in the subsequent compaction work.
[0015] As a further description of the above technical solution: a support frame is fixedly connected to the outer wall of the workbench, two cylinders are fixedly connected to the upper surface of the support frame, pressure plates are fixedly connected to the telescopic ends of the two cylinders, and guide rods are fixedly connected to both sides of the inside of the support frame.
[0016] By adopting the above technical solution, the cylinder drives the pressure plate to move down, and the pressure plate presses down on the stacked cardboard to compact the cardboard.
[0017] As a further description of the above technical solution: the pressure plate is slidably connected to the outer wall of the guide rod, the pressure plate is positioned above the first limiting rod and the second limiting rod, and the outer wall of the support frame is fixedly connected to a controller.
[0018] By adopting the above technical solution, the pressure plate is limited to slide on the outer wall of the guide rod, thereby achieving the limited sliding of the pressure plate and preventing the pressure plate from tilting.
[0019] By employing the above technical solution, the cardboard compaction device for preventing edge warping of this utility model has at least the following beneficial effects:
[0020] 1. Compared with the prior art, this anti-warping cardboard compaction device is equipped with a motor, a bidirectional lead screw, a lateral limiting component, a support base, a limiting rod, a motor, a bidirectional lead screw, a longitudinal limiting component, a support base, and a limiting rod. When the motor and motor are started, the motor drives the bidirectional lead screw to rotate, causing the two support bases to slide in the center and the two limiting rods to slide in the center, thus clamping and limiting the stacked cardboard laterally. The motor drives the bidirectional lead screw to rotate, causing the two support bases to slide in the center and the two limiting rods to slide in the center, thus clamping and limiting the stacked cardboard in the longitudinal direction. This achieves the effect of clamping and limiting the stacked cardboard in both the lateral and longitudinal directions, preventing the stacked cardboard from shifting or tipping over when compacting it.
[0021] 2. Compared with the prior art, this anti-warping cardboard compaction device is equipped with a support frame, guide rod, cylinder, pressure plate, outer shell 1, limit rod 1, spring 1, outer shell 2, limit rod 2, and spring 2. When the cylinder is activated, it drives the pressure plate to move downward and slide on the outer wall of the guide rod. When the pressure plate moves downward, it first applies pressure to limit rod 1 and limit rod 2, which in turn causes limit rod 1 and limit rod 2 to move downward and compress spring 1 and spring 2 respectively. After limit rod 1 and limit rod 2 move downward, they become flush with the stacked cardboard, thereby causing the pressure plate to compact the stacked cardboard. This not only achieves the compaction of the stacked cardboard, but also does not affect the limiting operation of limit rod 1 and limit rod 2 on the stacked cardboard. Attached Figure Description

Both sets of longitudinal limiting components 303 are slidably connected inside the worktable 1, thus limiting the longitudinal movement. Component 303 includes a second support base 305, which is threadedly connected to the outer wall of the second bidirectional lead screw 302. The second support base 305 is slidably connected to the inside of the worktable 1 and is limited to sliding inside the worktable 1. The transverse limiting component 203 also includes a first limiting rod 206, and the longitudinal limiting component 303 also includes a second limiting rod 306. Both the first limiting rod 206 and the second limiting rod 306 are slidably connected to the inside of the worktable 1 and are limited to sliding inside the worktable 1.
[0031] The lateral limiting assembly 203 also includes a first outer shell 204, which is fixedly connected to the upper surface of the second support base 205 and slidably connected inside the worktable 1. The first outer shell 204 limits the sliding mechanism inside the worktable 1.

A first spring 207 is provided inside the first outer shell 204, with one end fixedly connected to the lower surface of the first limiting rod 206 and the other end fixedly connected to the inside of the first outer shell 204.

[0032] Working Principle: First, the stacked cardboard is placed in the center of the upper part of workbench 1. Then, motors 201 and 301 are started. Motor 201 drives the bidirectional lead screw 202 to rotate, causing the two support seats 205 to slide centrally inside workbench 1. Simultaneously, the two outer shells 204 and two limiting rods 206 also slide centrally inside workbench 1. The central sliding of the two limiting rods 206 clamps and limits the horizontal sides of the stacked cardboard. Similarly, motor 301 drives the bidirectional lead screw 302 to rotate, causing the two support seats 305 to slide centrally inside workbench 1. This, in turn, causes the two outer shells 304 and two limiting rods 306 to slide centrally inside workbench 1. The central sliding of the two limiting rods 306 clamps and limits the vertical sides of the stacked cardboard. After clamping and limiting, the two cylinders 5 are activated to move the pressure plate 6 downwards. The pressure plate 6 slides along the outer wall of the guide rod 401. After the pressure plate 6 moves down a certain distance, it first applies pressure to the limiting rod 206 and the limiting rod 306, causing the limiting rod 206 and the limiting rod 306 to slide down into the inner shell 204 and the inner shell 304 respectively, while simultaneously compressing the spring 207 and the spring 307. When the pressure plate 6 presses down and drives the limiting rod 206 and the limiting rod 306 to move down to be flush with the stacked cardboard, the pressure plate 6 continues to move down to press against the stacked cardboard. Applying pressure achieves the compaction process. As the cardboard is compressed, the limiting rods 206 and 306 also move downwards due to the pressure applied by the pressure plate 6. During the compaction process, the limiting rods 206 and 306 remain flush with the stacked cardboard, thus not only compacting the stacked cardboard but also limiting its lateral and longitudinal movement, preventing the stacked cardboard from tipping over or shifting during the compaction process.
