Description

Technical Field

[0001] This utility model relates to the technical field of corrugated paper processing equipment, and in particular to a gluing and flattening device for the production of high-compression corrugated boxes. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard through die-cutting, creasing, stapling, or gluing. They are currently the most widely used packaging product, consistently ranking first in usage among all packaging materials. Due to their superior performance and good processing properties, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. For high-compression-strength corrugated cardboard boxes, in addition to their structural integrity, the most crucial element is the high-quality, high-compression-strength corrugated cardboard. During the production of existing high-compression-strength corrugated cardboard, it is essential to ensure the uniformity of the glue coating; otherwise, structural stress concentration will occur, significantly reducing the box's compressive strength.

[0003] Therefore, in the existing technology, before applying glue, the paper is usually flattened using a flattening roller. Although the existing glue-applying flattening device can meet the normal flattening requirements, it is still necessary to manually guide the end of the paper roll into each pressure roller assembly in sequence during feeding. This is not only cumbersome to operate, but also has a narrow space and poor visibility, which can easily lead to fingers getting caught. Although there is no risk of fingers getting caught when the equipment is not turned on, the operation process still has certain dangers and has room for improvement. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a gluing and flattening device for the production of high-compression corrugated boxes, thereby solving the above-mentioned problem.

[0005] To achieve the above objectives, a gluing and flattening device for producing high-compression corrugated boxes is provided, comprising a gluing feed seat, a first pressure roller assembly fixedly connected to the inner feed end of the gluing feed seat, a second pressure roller assembly disposed at the inner end of the gluing feed seat away from the first pressure roller assembly, two supporting sliding columns fixedly connected between the second pressure roller assembly and the first pressure roller assembly inside the gluing feed seat, two guide grooves symmetrically arranged on both sides of the inside of the gluing feed seat through the two supporting sliding columns, an opening groove provided at the end of each of the two guide grooves near the first pressure roller assembly, and a conical groove provided on the side of each of the two opening grooves away from the opening of the guide groove, and a threaded seat fixedly connected to the lower center of each of the two guide grooves, and an adjusting rod rotatably connected at the position corresponding to the threaded seat inside the gluing feed seat, the two ends of the adjusting rod being symmetrically provided with external threads, and an adjusting handwheel fixedly sleeved through the gluing feed seat at one end of the adjusting rod.

[0006] According to the aforementioned glue-coating and flattening device for producing high-compression corrugated boxes, the first pressure roller assembly includes two fixed seats, a pressure roller, a squeeze roller, a squeeze cylinder, a squeeze slide, a squeeze spring, and a roller shaft slide. Both ends of the pressure roller are rotatably connected to fixed seats. Both ends of the squeeze roller are rotatably connected to roller shaft slides. Both ends of the squeeze roller are slidably connected to corresponding fixed seats via roller shaft slides. A squeeze cylinder is fixedly connected to the middle of the end of each of the two fixed seats away from the pressure roller. A squeeze slide is slidably connected to the interior of each of the two fixed seats away from the pressure roller. The output ends of both squeeze cylinders pass through the fixed seats and are fixedly connected to the squeeze slides. Squeeze springs are fixedly connected to both sides of the end of each of the two squeeze slides away from the squeeze cylinders. The ends of both squeeze springs away from the squeeze slides are fixedly connected to both ends of the roller shaft slide.

[0007] According to the glue coating and flattening device for producing high-compression corrugated boxes, the second pressure roller assembly has the same structure as the first pressure roller assembly, and the second pressure roller assembly is arranged upside down relative to the first pressure roller assembly.

[0008] According to the gluing and flattening device for producing high-compression corrugated boxes, a limiting slide is fixedly connected at the lower end of each of the two guide grooves at a position corresponding to the two supporting slide columns, and the lower ends of the two guide grooves are slidably connected to the two supporting slide columns respectively through the corresponding limiting slide.

[0009] According to the glue-coating and flattening device for producing high-compression corrugated boxes, the opening directions of the two guide grooves are both at an upward 10-degree angle relative to the plane formed by the two supporting sliding columns.

[0010] According to the glue-coating and flattening device for producing high-compression corrugated boxes, both guide grooves are respectively engaged with the symmetrical external threads at both ends of the adjusting rod via threaded seats.

[0011] The above solution has at least one of the following beneficial effects:

[0012] 1. Compared with the prior art, this utility model sets two symmetrical guide grooves between two pressure roller assemblies, in conjunction with an open groove and a conical groove. During feeding, the paper output from the previous pressure roller assembly can be directly received. Then, the paper is guided by the guide grooves on both sides, so that the paper direction is always aligned with the next pressure roller assembly. This not only reduces the danger of manual guidance, but also limits the side of the paper, preventing the paper roll from being inaccurate during feeding. At the same time, the conical groove outside the open groove can also smooth the curled edges at the corners, preventing the guide groove from pressing the curled edges into creases, thus enhancing the practicality of the device.

[0013] 2. This utility model is equipped with an adjusting rod and symmetrical external threads. In conjunction with the threaded seat set below the guide groove, when the paper size changes, the symmetrical external threads on the adjusting rod can be rotated by rotating the adjusting handwheel, thereby making the guide grooves on both sides move synchronously and symmetrically. This facilitates adaptation to paper size and enhances the practicality of the device.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. Preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model provides a gluing and flattening device for producing high-compression corrugated boxes, including a gluing feed seat 1. A first pressure roller assembly 2 is fixedly connected to the inner feed end of the gluing feed seat 1. The first pressure roller assembly 2 includes two fixed seats 21, a pressure roller 22, a squeezing roller 23, a squeezing cylinder 24, a squeezing slide 25, a squeezing spring 26, and a roller shaft slide 27. Both ends of the pressure roller 22 are rotatably connected to the fixed seats 21. Both ends of the squeezing roller 23 are rotatably connected to the roller shaft slide 27. Both ends of the squeezing roller 23 are slidably connected to the corresponding fixed seats 21 via the roller shaft slide 27. A squeezing cylinder 24 is fixedly connected to the middle of the end of each fixed seat 21 away from the pressure roller 22. Slidably connected to the squeezing slide 25 is the inner end of each fixed seat 21 away from the pressure roller 22. The output ends of the two extrusion cylinders 24 are fixedly connected to the extrusion slide 25 through the fixed base 21. Extrusion springs 26 are fixedly connected to both sides of the end of the two extrusion slides 25 away from the extrusion cylinders 24. The ends of the two extrusion springs 26 away from the extrusion slides 25 are fixedly connected to both ends of the roller slide 27. The inner side of the glue feeding seat 1 is provided with a second pressure roller assembly 3 away from the first pressure roller assembly 2. The second pressure roller assembly 3 has the same structure as the first pressure roller assembly 2. The second pressure roller assembly 3 is upside down relative to the first pressure roller assembly 2. It can be extruded by the different curved surfaces of the pressure roller 22 and the extrusion roller 23. At the same time, by reversing the positions of the pressure roller 22 and the extrusion roller 23, the two sides of the paper are extruded respectively. After the extrusion cylinder 24 controls the extrusion force, a flattening effect is produced.

[0024] Inside the glue-applying feed seat 1, two supporting sliding columns 4 are fixedly connected between the second pressure roller assembly 3 and the first pressure roller assembly 2. Two guide grooves 5 are symmetrically arranged on both sides of the inside of the glue-applying feed seat 1 via the two supporting sliding columns 4. A limiting slide block 10 is fixedly connected at the lower end of each guide groove 5 at a position corresponding to the two supporting sliding columns 4. The lower ends of each guide groove 5 are slidably connected to the two supporting sliding columns 4 via corresponding limiting slide blocks 10. The opening direction of each guide groove 5 is relative to the plane formed by the two supporting sliding columns 4. The surface has an upward 10-degree angle. Utilizing the inherent characteristics of the high-strength corrugated base paper, the paper can form a micro-arched structure to provide support and prevent the paper from collapsing in the middle. Both guide grooves 5 are provided with an opening groove 11 at one end near the first pressure roller assembly 2. Both opening grooves 11 are provided with a conical groove 12 on the side away from the opening of the guide groove 5. The conical groove 12 on the outside of the opening groove 11 can smooth the curled edge at the edge of the paper by gradually narrowing the space when the paper is fed at the end, preventing the guide groove from pressing the curled edge of the paper into a crease.

[0025] Both guide slots 5 are fixedly connected to the lower center of a threaded seat 9. An adjusting rod 6 is rotatably connected inside the glue-coating feed seat 1 at a position corresponding to the threaded seat 9. The two ends of the adjusting rod 6 are symmetrically provided with external threads 7. Both guide slots 5 are threadedly engaged with the two ends of the adjusting rod 6 via the threaded seat 9. An adjusting handwheel 8 is fixedly sleeved at one end of the adjusting rod 6 through the glue-coating feed seat 1. When the paper specifications change, the symmetrical external threads 7 on the adjusting rod 6 can be rotated by rotating the adjusting handwheel 8, thereby causing the guide slots 5 on both sides to move synchronously and symmetrically for position adjustment, which is convenient for adapting to the paper specifications.

[0026] Working principle: In operation, this utility model uses two symmetrical guide grooves 5 between two pressure roller assemblies, along with an open groove 11 and a conical groove 12. During feeding, the paper from the previous pressure roller assembly can be directly received. The guide grooves 5 on both sides guide the paper, ensuring that the paper direction is always aligned with the next pressure roller assembly. This not only reduces the danger of manual guidance but also limits the side of the paper, preventing the paper roll from being misaligned during feeding. At the same time, the conical groove 12 on the outside of the open groove 11 can smooth the curled edges at the corners, preventing the guide groove from pressing the curled edges into creases. When the paper specifications change, the symmetrical external threads 7 on the adjusting rod 6 are rotated by turning the adjusting handwheel 8, thereby causing the guide grooves 5 on both sides to move synchronously and symmetrically, facilitating adaptation to paper specifications.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
