Description

Technical Field

[0001] This utility model relates to the field of furniture packaging equipment technology, and in particular to a pre-compression and shaping structure for packaging boxes. Background Technology

[0002] After furniture is manufactured, it is packaged in boxes before leaving the factory to ensure effective protection of its appearance during subsequent transportation. Currently, furniture packaging is automated using packaging production lines.

[0003] When using a packaging production line, the furniture is first placed manually into the packaging box, and then placed on the conveyor device to be transported to the next packaging station. In the actual production process, the box lid may be tilted up. When entering the packaging station, the tilted lid is closed and packed, which can easily cause the packaging box to twist, resulting in poor packaging effect. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by providing a pre-compression and shaping structure for packaging boxes.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a pre-compression and shaping structure for packaging boxes, mounted on a conveying device, comprising: The vertical beam has one end set on the side of the transmission device and the other end extends to the top of the conveying device and is spaced apart from the conveying surface of the conveying device. A guide is provided at the other end of the vertical beam and extends along the conveying direction of the conveying device; The preload plate is set horizontally and guided along the vertical direction at the other end of the vertical beam; The drive unit is connected to the preload plate at one end and to the vertical beam at the other end, and is used to drive the preload plate to move in the vertical direction.

[0006] Furthermore, along the conveying direction of the conveying device, the preload plate is disposed in the middle region of the guide.

[0007] Furthermore, a crossbeam is provided at the other end of the vertical beam, the crossbeam extends along the direction of the conveying device, and the guide and the preload plate are both provided on the crossbeam.

[0008] Furthermore, a mounting plate is detachably and fixedly connected to the crossbeam. The mounting plate is vertically arranged, and two guide sleeves are spaced apart on the mounting plate. Each guide sleeve is fitted with a guide rod, and the lower end of the guide rod is connected to the preload plate.

[0009] Furthermore, the driving device is a double-acting cylinder mounted on the mounting plate, and the driving rod of the double-acting cylinder is connected to the preload plate.

[0010] Furthermore, the guide is provided with two first ear plates spaced apart, and the crossbeam is provided with a first connector and a second connector spaced apart. A linear telescopic rod is hinged to the first connector, one first ear plate is hinged to the other end of the linear telescopic rod, and the other first ear plate is hinged to the second connector.

[0011] Furthermore, a perforated plate is provided at the other end of the vertical beam, and the perforated plate is detachably and fixedly connected to the horizontal beam.

[0012] Furthermore, guide grooves are provided on both sides of the crossbeam along the extension direction.

[0013] Compared with the prior art, the pre-compression and shaping structure for packaging boxes disclosed in this utility model has the following advantages: it can guide the box lid downward through the guide component, achieving an initial downward pressure effect and minimizing the height of the box lid's tilt. When the packaging box moves directly under the pre-compression plate, the transmission device stops, and the drive device then pushes the pre-compression plate downward a certain distance to pre-compress the box lid again, thereby ensuring minimal tilt of the box lid. Pre-compressing and shaping the packaging box effectively avoids the distortion of the packaging box caused by the tilting of the box lid, improving the quality of subsequent packaging.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please refer to Figure 1-7 As a specific implementation, this utility model provides a pre-compression and shaping structure for packaging boxes, which is disposed on a conveying device 1 and includes: The vertical beam 20 has one end located on the side of the transmission device and the other end extending above the transmission device 1 and spaced apart from the transmission surface of the transmission device 1. The guide 22 is disposed at the other end of the vertical beam 20 and extends along the conveying direction of the conveying device 1; The preload plate 23 is horizontally set and guided along the vertical direction at the other end of the vertical beam 20; The driving device is connected at one end to the preload plate 23 and at the other end to the vertical beam 20, and is used to drive the preload plate 23 to move in the vertical direction.

[0024] Specifically, in this application, the conveying device 1 is a roller drive belt commonly used in the art. The vertical beam 20 has an L-shaped structure, with a connecting plate 201 welded to its lower end. The connecting plate 201 is threadedly connected to the side of the base of the conveying device 1 via a screw. The other end is bent towards the conveying device 1, thus positioned above it. This application provides a guide at the other end of the vertical beam 20. Specifically, the guide is a rigid rod. Along the conveying direction of the conveying device 1, the downstream end of the guide is lower than the upstream end. Through this arrangement, the packaging is conveyed by the conveying device 1. When the box passes the guide, the guide can guide and press down the box lid, achieving an initial pressing effect and minimizing the height of the lid's tilt. When the packaging box moves directly under the pre-pressing plate 23, the transmission device stops, and the drive device works to push the pre-pressing plate 23 downward a certain distance, pre-pressing the box lid again. This ensures that the box lid warps minimally, pre-pressing and shaping the packaging box. Then, the conveying device 1 works again to transport the packaging box to the packing station for packaging. This effectively avoids the twisting of the packaging box caused by the tilting of the box lid, improving the quality of subsequent packaging.

[0025] Furthermore, as a preferred embodiment, the preload plate 23 is disposed in the middle region of the guide member 22 along the conveying direction of the conveying device 1. (See reference) Figure 1 , Figure 6 The pre-pressing plate 23 moves vertically and is positioned in the middle area of ​​the guide 22. With this arrangement, when the conveying device 1 conveys the packaging box, it stops conveying the packaging box directly below the guide 22. At this time, the pre-pressing plate 23 can press the middle area of ​​the packaging box, resulting in a good pressing effect.

[0026] It should be noted that the control method for stopping and operating the transmission device 1 is a conventional technical means in the field. This application adopts the prior art in this way, and it will not be described in detail here. Those skilled in the art should understand.

[0027] Furthermore, as a specific implementation method, refer to Figures 2-5 The other end of the vertical beam 20 is provided with a horizontal beam 21, which extends along the direction of the conveying device 1. The guide 22 and the pre-pressure plate 23 are both disposed on the horizontal beam 21. Specifically, by horizontally setting the horizontal beam 21, the guide 22 and the pre-pressure plate 23 can be disposed on the horizontal beam. Since the horizontal beam 21 has a certain length, the position of the pre-pressure plate 23 on the horizontal beam 21 can be adjusted as needed to ensure the pre-pressure effect on the packaging box below.

[0028] Furthermore, specifically, a mounting plate 212 is detachably and fixedly connected to the crossbeam 21. The mounting plate 212 is vertically arranged, and two guide sleeves 232 are spaced apart on the mounting plate 212. Each guide sleeve 232 guides and engages with a guide rod 230, the lower end of which is connected to the preload plate 23. Specifically, by setting the mounting plate 212, the mounting plate 212 is connected to the crossbeam 21, and the guide rod 230 and the driving device are both set on the mounting plate 212. The preload plate 23 is set at the lower end of the guide rod 230 and the driving device. When the preload plate 23 needs to be adjusted, only the position of the mounting plate 212 needs to be adjusted, which is convenient for adjustment.

[0029] Furthermore, as a specific implementation method, refer to Figure 7The driving device is a double-acting cylinder 231 mounted on the mounting plate 212, and the driving rod of the double-acting cylinder 231 is connected to the preload plate 23. Guide sleeves 232 are detachably fixed on the mounting plate 212, and an L-shaped support member 213 is provided between the two guide sleeves 232. The support member 213 has a plate-like structure. In a specific embodiment, the double-acting cylinder 231 can be connected to the support member 213 via a flange, and the telescopic rod of the double-acting cylinder 231 is connected to the preload plate 23, thereby enabling the up-and-down driving of the preload plate 23. It should be noted that the double-acting cylinder 231 is a standard part used in the art, having two air inlets located at both ends of the cylinder barrel. The extension and retraction of the piston are both driven by compressed gas, and bidirectional movement is achieved by alternating pressure on both sides. Further details are omitted here, but those skilled in the art should understand.

[0030] Furthermore, as a specific implementation method, refer to Figure 3 , Figure 4 The guide member has two first ear plates 22a spaced apart. The crossbeam 21 has a first connector 210 and a second connector 211 spaced apart. A linear telescopic rod 220 is hinged to the first connector 210. One first ear plate 22a is hinged to the other end of the linear telescopic rod 220, and the other first ear plate 22a is hinged to the second connector 211. Specifically, the two first ear plates 22a are welded to the guide member. A second ear plate 2201 is provided on the side of the first connector 210. The linear telescopic rod 220 can be a manual telescopic rod or a pneumatic telescopic rod. One end of the linear telescopic rod 220 is hinged to the second ear plate 2201, and the other end is hinged to the other first ear plate 22a. With this arrangement, the tilt angle of the guide member can be adjusted by adjusting the extension of the linear telescopic rod 220.

[0031] Furthermore, as a specific implementation method, refer to Figure 5 The other end of the vertical beam 20 is provided with a perforated plate 202, which is detachably and fixedly connected to the crossbeam 21. Specifically, by providing a perforated plate 202 at the end of the vertical beam 20, and by threading a screw through the perforated plate 202 and connecting it to a threaded hole on the crossbeam 21, the crossbeam 21 is fixed. This method facilitates the connection and disassembly of the crossbeam 21, making maintenance easier. Furthermore, multiple sets of threaded holes can be provided on the crossbeam 21 along its length, allowing the crossbeam 21 to be adjusted in position along its length as needed.

[0032] Furthermore, as a specific implementation, guide grooves are provided on both sides of the crossbeam 21 along the extending direction. Specifically, refer to... Figures 3-5The guide groove is preferably a T-shaped groove. By setting the T-shaped groove, a T-shaped nut can be set in the T-shaped groove, and the threaded hole on the T-shaped nut can be connected to the bolt on the hole plate 202, which is more convenient to use. Similarly, the first connecting member 210 and the second connecting member 211 are both connected to the T-shaped nut by threaded screws to achieve connection with the crossbeam 21. This method also facilitates the position adjustment of the first connecting member 210 and the second connecting member 211.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
