Description

Technical Field

[0001] This application relates to the field of cardboard box production equipment technology, and in particular to a compression-resistant cushioning structure forming machine for cardboard boxes. Background Technology

[0002] The compression-resistant and cushioning structure of a cardboard box is key to improving packaging protection performance, and mainly includes corrugated cardboard, honeycomb structures, and padding dividers. Corrugated cardboard uses different wave-shaped structures (A, B, C, E types, etc.) to disperse pressure, achieving cushioning and compression resistance; honeycomb structures utilize the efficient mechanical properties of hexagons to evenly distribute pressure, making them suitable for heavy-duty packaging; padding and divider structures use corner protectors, partitions, and other locally thickened designs to specifically protect vulnerable areas. In practical applications, composite structures are often used, such as corrugated cardboard combined with pearl cotton lining, or foldable rigid structures, balancing rigid support and flexible cushioning. By optimizing parameters such as material weight, number of corrugated layers, and box dimensions, the protection requirements of different transportation scenarios can be met.

[0003] In practical use, it has been found that existing forming machines generally lack an effective fixing mechanism for cardboard. During the forming process, the cardboard is placed only with simple limiting or manual assistance, making it highly susceptible to displacement or shifting due to mechanical vibration, rolling forces, and other factors. This not only makes it difficult to guarantee the dimensional accuracy of the cushioning structure, resulting in problems such as crease misalignment and structural asymmetry, but also reduces the forming pass rate, increases the scrap rate, and raises production costs. Therefore, we propose a compression-resistant cushioning structure forming machine for cardboard boxes to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies, such as cardboard being easily displaced or shifted due to mechanical vibration, rolling force, etc., when placed with only simple limiting or manual assistance, resulting in creases, misalignment, and structural asymmetry. Therefore, this application proposes a compression-resistant and cushioning structure forming machine for cardboard boxes.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a compression-resistant buffer structure forming machine for cardboard boxes, including a bottom box, a top plate provided above the bottom box, a back plate fixedly installed on the top plate and the rear side of the bottom box, a lifting mechanism provided on the top plate, a hollow seat fixedly installed on the top of the bottom box, an adsorption mechanism provided on the hollow seat; a forming frame provided below the top plate, a forming mechanism provided inside the forming frame, a pushing mechanism provided on both sides of the forming frame, the forming frame and the hollow seat being adapted to each other, an ejection mechanism provided on the hollow seat, a piston cylinder fixedly installed on the inner wall of the bottom of the bottom box, a piston mechanism provided inside the piston cylinder, a vent pipe provided outside the piston cylinder, and the vent pipe extending to the outside of the bottom box. It is worth noting that the vent pipe can balance the air pressure inside and outside the piston cylinder during the operation of the piston mechanism.

[0008] A further feature of this application is that the molding mechanism includes a mounting base and a heating roller, with mounting bases fixedly installed on the inner walls of the molding frame, and heating rollers rotatably mounted on the mounting bases.

[0009] By adopting the above technical solution and by setting up a forming mechanism, the heating roller can heat and roll the adsorbed and fixed compression-resistant cushioning paperboard, so as to use temperature and pressure to make the compression-resistant cushioning paperboard bend along the crease line and gradually form it into a structure with compression-resistant cushioning function.

[0010] A further configuration of this application is as follows: the piston mechanism includes a piston plate and a piston rod, the piston plate is slidably installed inside the piston cylinder, the piston rod is fixedly installed on the top of the piston plate, the top of the piston rod is fixedly connected to the bottom of the lifting plate, and the piston rod is located outside the forming frame and the hollow seat.

[0013] By adopting the above technical solution and by setting up an adsorption mechanism, the air inside the hollow seat is drawn through the air extraction pipe to the piston plate inside the piston cylinder. The reduced air creates a negative pressure at the adsorption hole at the top of the hollow seat, thereby firmly adsorbing and fixing the pressure-resistant buffer cardboard placed on the top of the hollow seat.

[0014] A further feature of this application is that the ejection mechanism includes a sliding plate and a spring, the sliding plate is slidably sleeved on the outer side of the hollow seat, and springs are fixedly installed on both sides of the bottom of the sliding plate, with the bottom end of the springs fixedly connected to the top of the bottom box.

[0016] A further feature of this application is that the pushing mechanism includes a connecting seat and a push rod, with connecting seats fixedly installed on both sides of the forming frame, and a push rod fixedly installed at the bottom of the connecting seat, the bottom end of the push rod being adapted to the top of the slide plate.

[0017] By adopting the above technical solution and by setting up a pushing mechanism, the forming frame can drive the push rod to move downward through the connecting seat, thereby achieving the purpose of pushing the slide plate downward through the push rod.

[0018] A further feature of this application is that a sliding rod is fixedly installed on the top of the lifting plate, the top end of the sliding rod extends above the top plate, and the sliding rod is slidably connected to the top plate.

[0019] By adopting the above technical solution and by setting up a sliding rod, the lifting plate can move more smoothly up and down.

[0020] The beneficial effects of this application are:

The adsorption hole at the top of the hollow seat forms a negative pressure due to the reduction of air, thereby firmly adsorbing and fixing the pressure-resistant buffer cardboard placed on the top of the hollow seat, which can achieve the purpose of preventing the pressure-resistant buffer cardboard from shifting in subsequent processing.

[0022] (2) Through the cooperation of hydraulic cylinder, lifting plate, forming frame, mounting base and heating roller, the hydraulic cylinder can drive the forming frame to move downward, and can heat and roll the adsorbed and fixed anti-compression buffer paperboard, and can use temperature and pressure to make the anti-compression buffer paperboard bend along the crease line, and gradually form a structure with anti-compression buffer function.

[0032] See Figures 1-5 This application provides a compression-resistant cushioning structure forming machine for cardboard boxes, including a bottom box 1, a top plate 2 above the bottom box 1, a back plate 8 fixedly installed on the rear side of the top plate 2 and the bottom box 1, a lifting mechanism on the top plate 2, a hollow seat 3 fixedly installed on the top of the bottom box 1, an adsorption mechanism on the hollow seat 3, a forming frame 4 below the top plate 2, a forming mechanism inside the forming frame 4, a pushing mechanism on both sides of the forming frame 4, the forming frame 4 and the hollow seat 3 being adapted to each other, an ejection mechanism on the hollow seat 3, a piston cylinder 5 fixedly installed on the inner wall of the bottom of the bottom box 1, a piston mechanism inside the piston cylinder 5, and a vent pipe 504 on the outer side of the piston cylinder 5 extending to the outer side of the bottom box 1.

[0033] Specifically, the lifting mechanism includes a hydraulic cylinder 201 and a lifting plate 202. The hydraulic cylinder 201 is fixedly installed on the top of the top plate 2. The output shaft of the hydraulic cylinder 201 extends to the bottom of the top plate 2. The lifting plate 202 is fixedly installed at the bottom of the output shaft of the hydraulic cylinder 201. The bottom of the lifting plate 202 is fixedly connected to the top of the forming frame 4.

[0034] Specifically, the forming mechanism includes a mounting base 401 and a heating roller 402. The mounting base 401 is fixedly installed on the inner walls of the forming frame 4, and the heating roller 402 is rotatably mounted on the mounting base 401.

[0035] Specifically, the piston mechanism includes a piston plate 501 and a piston rod 502. The piston plate 501 is slidably installed inside the piston cylinder 5, and the piston rod 502 is fixedly installed on the top of the piston plate 501. The top of the piston rod 502 is fixedly connected to the bottom of the lifting plate 202, and the piston rod 502 is located outside the forming frame 4 and the hollow seat 3.

[0036] Specifically, the adsorption mechanism includes an air extraction pipe 503 and an adsorption hole 301. The same air extraction pipe 503 is provided between the piston cylinder 5 and the hollow seat 3. The bottom end of the air extraction pipe 503 is located above the piston plate 501, and the top of the hollow seat 3 is provided with an adsorption hole 301.

[0037] Specifically, the ejection mechanism includes a slide plate 6 and a spring 601. The slide plate 6 is slidably mounted on the outer side of the hollow seat 3. Springs 601 are fixedly installed on both sides of the bottom of the slide plate 6. The bottom end of the spring 601 is fixedly connected to the top of the bottom box 1.

[0038] Specifically, the pushing mechanism includes a connecting seat 7 and a push rod 701. The connecting seat 7 is fixedly installed on both sides of the forming frame 4, and the push rod 701 is fixedly installed at the bottom of the connecting seat 7. The bottom end of the push rod 701 is adapted to the top of the slide plate 6.

[0039] Specifically, a sliding rod is fixedly installed on the top of the lifting plate 202, with the top end of the sliding rod extending above the top plate 2, and the sliding rod is slidably connected to the top plate.

[0040] In this application, during operation, the pressure-resistant cushioning cardboard with indentations after rolling is first placed on top of the hollow seat 3. When the hydraulic cylinder 201 is activated, its output shaft drives the lifting plate 202 to move downward. Since the top of the piston rod 502 is fixedly connected to the bottom of the lifting plate 202, the piston rod 502 drives the piston plate 501 to slide downward in the piston cylinder 5, which increases the space above the piston plate 501 and forms a negative pressure. At this time, the air in the hollow seat 3 is drawn to the piston plate 501 in the piston cylinder 5 through the air extraction pipe 503. Due to the reduction of air, a negative pressure is formed at the suction hole 301 at the top of the hollow seat 3, thereby firmly adsorbing and fixing the pressure-resistant cushioning cardboard placed on top of the hollow seat 3, which can achieve the purpose of preventing the pressure-resistant cushioning cardboard from shifting in subsequent processing.

[0041] As the lifting plate 202 continues to descend, the push rods 701 at the bottom of the connecting seats 7 on both sides of the forming frame 4 contact the top of the slide plate 6 and push the slide plate 6 downward. The slide plate 6 compresses the spring 601 at the bottom, accumulating elastic potential energy for the subsequent ejection of the formed buffer structure. When the forming frame 4 and the hollow seat 3 are fully engaged, the heating rollers 402 on the mounting seats 401 around the inside of the forming frame 4 begin to work. They can heat and roll the adsorbed and fixed anti-compression buffer cardboard, and can use temperature and pressure to make the anti-compression buffer cardboard bend along the crease line, gradually forming a structure with anti-compression buffer function.

[0042] After the molding process is completed, the output shaft of the hydraulic cylinder 201 drives the lifting plate 202 to retract upwards, and the piston rod 502 drives the piston plate 501 to slide upwards inside the piston cylinder 5. The space above the piston plate 501 shrinks, and the internal gas can be discharged to the outside of the bottom box 1 through the vent pipe 504 on the outside of the piston cylinder 5. The negative pressure state inside the hollow seat 3 is released, and the adsorption force disappears. At the same time, as the molding frame 4 rises, the push rod 701 disengages from the slide plate 6, and the compressed spring 601 restores its elastic deformation, releasing elastic potential energy to push the slide plate 6 upwards. This allows the slide plate 6 to push the molded pressure-resistant buffer structure out from the top of the hollow seat 3, which facilitates collection and subsequent processing by the operator.
