Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, and in particular to a steam-heated corrugated cardboard production equipment. Background Technology

[0002] Existing steam-heated corrugated cardboard production equipment includes an unwinding mechanism, a preheating mechanism, a corrugating mechanism, an adhesive bonding mechanism, a drying and shaping mechanism, a cooling and conveying mechanism, and a cutting mechanism. The preheating and drying and shaping mechanisms use steam heating to improve production efficiency and cardboard quality. The equipment softens the base paper by heating the preheating rollers with steam, making it easier to form. The core paper is then processed into a corrugated shape by using corrugated rollers in conjunction with steam heating. Adhesive is then applied evenly to the corrugated ridges and bonded to the face paper or liner paper. After production, the corrugated cardboard needs to be cut to the appropriate size.

[0003] A Chinese patent has been published: a cutting device for corrugated cardboard processing, patent announcement number: 202121064465.5. The patent "includes a cutting base plate, on both sides of the cutting base plate are provided with second sliding grooves, a second screw is rotatably arranged inside the second sliding groove, a second slider is threadedly sleeved on the outer side of the second screw, a support plate is fixedly connected to the outer side of the second slider, and a top plate is fixedly connected to the upper end of the support plate."

[0004] Although the device uses a clamping mechanism to limit the corrugated cardboard and prevent it from shifting during cutting, thus avoiding crooked cuts, it primarily uses a two-sided clamping method to hold the cardboard stable during the cutting process. However, because corrugated cardboard is lightweight and has a certain degree of elasticity, relying solely on two-sided clamping is insufficient to achieve complete fixation, especially during high-precision cutting. Unclamped areas of the cardboard, such as the front and back, are prone to warping, shaking, or shifting during cutting, resulting in uneven cut edges and even affecting subsequent processing and use, impacting cutting quality, and causing deviations in cut dimensions. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a steam-heated corrugated cardboard production equipment to solve the problem that the unclamped areas of the cardboard, such as the front and back, are prone to warping, shaking or shifting during cutting, resulting in uneven cutting edges and even affecting subsequent processing and use.

[0006] To achieve the above objectives, this utility model provides a steam-heated corrugated cardboard production equipment, including a workbench. A cutting table is fixedly connected to the top of the workbench. Through slots are provided on the four sides of the top of the workbench near the cutting table. A support plate is fixedly connected to the side wall of the workbench. An electric telescopic rod is fixedly connected to the top of the support plate. An installation plate is fixedly connected to the output end of the electric telescopic rod. Sliding columns are connected through the four corners of the installation plate. A die-cutting plate is fixedly connected between the bottom ends of the sliding columns. A clamping mechanism for clamping and limiting the corrugated cardboard is provided at the bottom of the workbench.

[0007] Preferably, the clamping mechanism includes a rotating plate rotatably connected to the bottom of a plurality of through slots. The rotating plate is V-shaped. A clamping plate is fixedly connected to the top of the rotating plate. A roller is rotatably connected to the bottom of the rotating plate. A reciprocating spring is fixedly connected between the side wall of the rotating plate and the bottom of the worktable. A synchronization plate is fixedly connected to the side wall of the mounting plate. A linkage plate is fixedly connected to the bottom end of the synchronization plate. The linkage plate is cross-shaped. The outer wall of the roller is in contact with the top of the linkage plate.

[0008] Preferably, a pusher plate is slidably connected to the top of the workbench near the side wall of the cutting table, and two compression springs are fixedly connected between the pusher plate and the opposite side of the cutting table. A pusher block is fixedly connected to the side wall of the synchronization plate.

[0009] Preferably, the top of the pusher block is arc-shaped, the pusher plate is bow-shaped, and when the pusher block rises, the top of the pusher block contacts the side wall of the pusher plate.

[0010] Preferably, buffer springs are fitted on the outer walls of the sliding columns at the four corners of the mounting plate, with the top end of the buffer springs fixedly connected to the bottom of the mounting plate and the bottom end of the buffer springs fixedly connected to the top of the die-cutting plate.

[0011] Preferably, the through groove near the synchronization plate is connected to the side wall of the worktable.

[0012] The beneficial effects of this utility model are:

[0013] 1. This steam-heated corrugated cardboard production equipment utilizes a clamping mechanism where an electric telescopic rod drives the die-cutting plate to descend synchronously. The synchronous plate moves downwards along with it, causing the linkage plate to descend as well. As the linkage plate slowly descends, it releases the limit on the rotating plate. At this point, under the compression of the reciprocating spring, the rotating plate rotates within the slot, causing one end of its roller to abut against the linkage plate, while the other end drives the clamping plate to rotate. This achieves synchronous clamping and limiting of the four sides of the corrugated cardboard. Subsequently, the die-cutting plate mechanically cuts the corrugated cardboard, ensuring improved cutting accuracy. This clamping mechanism, through its linkage clamping design, effectively avoids the cardboard offset, warping, or misalignment problems caused by clamping only two sides during traditional cutting processes. This further improves cutting accuracy and finished product quality, making the equipment more suitable for high-precision corrugated cardboard production needs.

[0014] 2. This steam-heated corrugated cardboard production equipment, through the upward movement of the synchronous plate, also drives the pusher block to move upward, and through its specific structure, pushes the pusher plate. During this process, the pusher plate slides on the top of the worktable and squeezes the compression spring. Using the pushing force at both ends, it pushes the corrugated cardboard on the top of the cutting table outward, causing it to partially leave the top of the cutting table. At this time, the operator does not need to reach into the cutting table to directly pick up the exposed corrugated cardboard, thereby improving the convenience and safety of picking up materials, reducing the inconvenience caused by reaching deep into the cutting table, and improving production efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 4 As shown, a steam-heated corrugated cardboard production equipment includes a workbench 1, a cutting table 2 fixedly connected to the top of the workbench 1, through slots 3 on the four sides of the top of the workbench 1 near the cutting table 2, a support plate 4 fixedly connected to the side wall of the workbench 1, an electric telescopic rod 5 fixedly connected to the top of the support plate 4, an installation plate 6 fixedly connected to the output end of the electric telescopic rod 5, sliding columns 7 penetrating through the four corners of the installation plate 6, a die-cutting plate 8 fixedly connected between the bottom ends of the sliding columns 7, and a clamping mechanism for clamping and limiting the corrugated cardboard at the bottom of the workbench 1.

[0025] Further, see attached document. Figure 2 and Figure 3As shown, the clamping mechanism includes a rotating plate 9 rotatably connected to the bottom of multiple through slots 3. The rotating plate 9 is V-shaped. A clamping plate 10 is fixedly connected to the top of the rotating plate 9. A roller 11 is rotatably connected to the bottom of the rotating plate 9. A reciprocating spring 12 is fixedly connected between the side wall of the rotating plate 9 and the bottom of the worktable 1. A synchronization plate 13 is fixedly connected to the side wall of the mounting plate 6. A linkage plate 14 is fixedly connected to the bottom end of the synchronization plate 13. The linkage plate 14 is cross-shaped. The outer wall of the roller 11 is in contact with the top of the linkage plate 14.

[0026] When using the clamping mechanism, the corrugated cardboard is first placed on top of the cutting table 2. After powering on, the electric telescopic rod 5 is activated, driving the mounting plate 6 to move downwards. The mounting plate 6 drives the die-cutting plate 8 to descend synchronously via the sliding column 7 and the buffer spring 18. At the same time, the synchronous plate 13 moves downwards and drives the linkage plate 14 to descend synchronously. When the linkage plate 14 descends slowly, it releases the limit on the rotating plate 9. At this time, under the squeezing action of the reciprocating spring 12, the rotating plate 9 rotates in the through groove 3, so that the roller 11 at one end abuts against the linkage plate 14, while the other end drives the clamping plate 10 to rotate, realizing the synchronous clamping and limiting of the four sides of the corrugated cardboard. Subsequently, the die-cutting plate 8 mechanically cuts the corrugated cardboard, ensuring improved cutting accuracy. This clamping mechanism, through its linkage clamping design, effectively avoids the cardboard offset, warping, or misalignment problems caused by clamping only two sides in the traditional cutting process, further improving cutting accuracy and finished product quality, making the equipment more suitable for high-precision corrugated cardboard production needs.

[0027] Further, see attached document. Figure 3 and Figure 4 As shown, a pusher plate 15 is slidably connected to the top of the workbench 1 near the side wall of the cutting table 2. Two compression springs 16 are fixedly connected between the pusher plate 15 and the opposite side of the cutting table 2. A pusher block 17 is fixedly connected to the side wall of the synchronization plate 13. The top of the pusher block 17 is arc-shaped, and the pusher plate 15 is bow-shaped. After cutting, the die-cutting plate 8 is driven to move upward by the electric telescopic rod 5, which at the same time drives the synchronization plate 13 and the linkage plate 14 to rise. When the linkage plate 14 moves to a specific position, it contacts the roller 11 and further drives the rotating plate 9 to rotate, so that the clamping plate 10 gradually separates from the side wall of the corrugated cardboard, thereby releasing the clamping limit on the cardboard.

[0028] At the same time, the upward movement of the synchronization plate 13 will also drive the pusher block 17 to move upward, and push the pusher plate 15 through its specific structure. During this process, the pusher plate 15 slides on the top of the worktable 1 and squeezes the compression spring 16. Using the pushing force at both ends, the corrugated cardboard on the top of the cutting table 2 is pushed outward, so that it is partially removed from the top of the cutting table 2. At this time, the workers do not need to put their hands into the cutting table 2 to directly pick up the exposed corrugated cardboard, thereby improving the convenience and safety of picking up materials, reducing the inconvenience caused by reaching deep into the material, and improving production efficiency.

[0029] Further, see attached document. Figure 2 As shown, buffer springs 18 are fitted on the outer walls of the sliding columns 7 at the four corners of the mounting plate 6. The top end of the buffer spring 18 is fixedly connected to the bottom of the mounting plate 6, and the bottom end of the buffer spring 18 is fixedly connected to the top of the die-cutting plate 8. The buffer spring 18 plays a buffering role when the die-cutting plate 8 cuts the corrugated cardboard.

[0030] Further, see attached document. Figure 2 As shown, the through groove 3 on the side near the synchronous plate 13 is connected to the side wall of the worktable 1, so as not to hinder the pusher block 17 from moving upward and pushing the pusher plate 15.
