Description

Technical Field

[0001] This application relates to the technical field of packaging production, and in particular to a packaging box pressure device and packaging box production equipment. Background Technology

[0002] In the packaging industry, the production of packaging boxes has always been a crucial step. High-quality packaging boxes better protect goods and enhance their appearance, which is essential for sales and transportation. At the same time, improving packaging box production efficiency can reduce production costs and enhance a company's competitiveness in the market. Therefore, packaging box production technology is constantly evolving and innovating to meet market demands.

[0003] Initially, the packaging boxes are flat pieces of cardboard, not unfolded into cartons. In traditional packaging box production, after the cardboard is glued into a flat box, a pressure application station is usually used to improve the bonding strength. Common pressure application methods include manual pressure, where workers press the box with simple tools. However, this method is not only labor-intensive, but it is also difficult to ensure that the pressure force and duration are uniform and stable. Another method uses simple mechanical devices for pressure application, such as two conveyor belts arranged vertically with a gap in between for the box to pass through, and then the box is squeezed and transported. However, this device often can only apply pressure once, and the pressure intensity must be adjusted according to the size of the gap between the two belts, making it impossible to adjust the pressure process according to actual needs. In addition, extending the station to increase the pressure time not only wastes floor space but also affects production efficiency.

[0004] Therefore, whether applying pressure manually or using simple mechanical devices, it is difficult to precisely control the pressure application process. If the pressure application time is too short, it is difficult to fully guarantee the adhesion of the packaging box; if it is too long, it will affect the overall production efficiency of the production equipment, resulting in inconsistent adhesion quality of the packaging boxes and affecting the overall quality and performance of the packaging boxes. Summary of the Invention

[0005] In order to further improve the bonding strength of packaging boxes without affecting overall production efficiency, the purpose of this application is to provide a packaging box pressure application device, which adopts the following technical solution: Includes receiving components, a rotary adjustment mechanism, and a pressing mechanism; The rotary adjustment mechanism is provided with at least two pressure stations evenly distributed along its rotation direction, and each pressure station is provided with the receiving component, which is used to receive and load the packaging box. The pressing mechanism is disposed above one of the working positions of the rotary adjustment mechanism. The pressing mechanism includes a pressing plate for applying pressure to the packaging box in the receiving component located below it and a first driving member for driving the pressing plate.

[0006] By adopting the above technical solution, a rotary adjustment mechanism with at least two evenly distributed pressure application stations is set up, and combined with a corresponding pressing mechanism, a highly efficient cyclic operation system is constructed. This design allows the loading, positioning, and pressing processes of the packaging box to be carried out continuously and alternately during rotation, achieving a tight connection of production rhythm. While not affecting overall production efficiency, it can also further improve the adhesive strength of the packaging box.

[0007] Optionally, the receiving component includes a support plate and a support box, the support box is fixedly mounted on the support plate, the support plate is detachably connected to the rotation adjustment mechanism, and the packaging box is placed inside the support box.

[0008] By adopting the above technical solution, the receiving component is clearly divided into a detachable support plate and a fixed support box. This structure not only facilitates the installation and replacement of the support box to adapt to packaging boxes of different sizes, but also allows the support plate to be stably connected to the rotary adjustment mechanism as a standard interface. The support box is specifically designed to hold the packaging box, effectively limiting its displacement during the pressure application process, ensuring the accuracy of the pressure application and the regularity of the packaging box's shape.

[0009] Optionally, a limit component is provided on the rotary adjustment mechanism for each of the pressure application stations, and the limit component is used to limit the movement of the bearing plate relative to the rotary adjustment mechanism in the horizontal direction.

[0010] By adopting the above technical solution and adding a limiting component, horizontal sliding or offset of the bearing plate can be effectively prevented during the operation of the rotary adjustment mechanism, ensuring that each bearing plate and its bearing box can be accurately stopped at the preset work position (especially the pressing work position). This greatly improves the positioning accuracy and operational stability of the equipment and is a key structure to ensure consistent pressure application quality.

[0011] Optionally, the rotary adjustment mechanism includes a conveying disk and a rotary power component. The bearing plate is detachably mounted on the conveying disk and positioned by the limiting component. The rotary power component is driven to the conveying disk to drive the conveying disk to rotate.

[0012] By adopting the above technical solution, using a conveyor disc as a carrying platform and precisely driven by a rotating power component, a stable and reliable intermittent rotary motion mode is provided. This structure offers smooth transmission, precise control, and easy switching between multiple workstations. The detachable connection between the carrying plate and the disc also facilitates daily maintenance and component replacement.

[0013] Optionally, a pressure detection component is provided between the support plate and the support box to detect the downward pressure transmitted from the support box to the support plate.

[0014] By adopting the above technical solution, a pressure detection component (such as a pressure sensor) is installed between the support plate and the support box, enabling the device to sense the total weight of the support box and the packaging boxes inside in real time. When the number of packaging boxes inside the support box reaches a certain level, the weight of the packaging boxes themselves will increase the downward pressure on the support box. When the pressure reaches a certain level, the real-time data will facilitate subsequent operations.

[0015] Optionally, the pressure detection component is electrically connected to the rotating power component. When the weight of the packaging box loaded in the carrier box causes the pressure detected by the pressure detection component to reach a preset loading threshold, the rotating power component drives the rotating adjustment mechanism to rotate, moving the carrier box to the bottom of the pressing plate.

[0016] By adopting the above technical solution, an electrical signal connection is established between the pressure detection component and the rotating power component, creating an intelligent triggering mechanism. When the loading of the packaging box is detected to be complete (weight reaches a preset threshold), the equipment can automatically start the rotation process, moving the fully loaded workpiece to the pressure application position. This realizes the automated logic of "transfer upon completion of loading," reducing human judgment or fixed-time waiting, optimizing production cycle time, and improving the level of intelligence.

[0017] Optionally, the first driving member is vertically arranged with its output end facing downwards, and the pressing plate is fixedly installed on the output end of the first driving member.

[0018] By adopting the above technical solution, a vertically positioned first driving component (such as a cylinder or electric push rod) is used to directly drive the pressing plate, ensuring that the direction of the applied pressure is vertically downward, consistent with the pressure direction that the packaging box needs to withstand. This design structure is simple and direct, with a short transmission chain, which is conducive to providing stable and controllable linear downward pressure, ensuring effective and uniform pressure application.

[0019] Optionally, the pressing mechanism further includes a support column and a second driving member. The first driving member is disposed on the top of the support column, and the second driving member is connected to the support column for driving the support column, together with the first driving member and the pressing plate, to rotate horizontally as a whole.

[0020] By adopting the above technical solution, the second driving component drives the support column to rotate the entire pressing unit horizontally, greatly enhancing the layout flexibility and applicability of the device. When the pressing station needs adjustment, maintenance, or to avoid interference areas, the pressing plate can be rotated away from the working area without affecting the operation of other stations, facilitating loading and unloading, maintenance, or handling of abnormal situations, and improving the operability and safety of the equipment.

[0021] Secondly, the packaging box production equipment provided in this application adopts the following technical solution: Includes a packaging box extrusion and conveying mechanism and the aforementioned packaging box pressure device; The carrier box in the packaging box pressing device, located at the feeding station, is positioned below the output port of the packaging box extrusion conveying mechanism, so that the packaging box can fall directly from the packaging box extrusion conveying mechanism into the carrier box.

[0022] By adopting the above technical solution, the loading station of the pressure device is directly connected to the output port of the packaging box extrusion conveyor, enabling the packaging box to fall seamlessly into the carrier box, realizing a continuous automated flow from the upstream forming / conveying process to this pressure process. This integrated design eliminates intermediate manual handling or transfer links, which not only significantly improves overall production efficiency but also effectively reduces the damage or deformation that may occur to the packaging box during transfer, optimizing the entire production line process.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. A rotary adjustment mechanism with at least two evenly distributed pressure application stations, combined with a corresponding pressing mechanism, is used to construct a highly efficient cyclic operation system. This design allows the loading, positioning, and pressing processes of the packaging boxes to be carried out continuously and alternately during rotation, achieving a tight connection of production cycles. While not affecting overall production efficiency, it can also further improve the adhesive strength of the packaging boxes. 2. By incorporating a pressure detection component linked to the drive mechanism, the device achieves intelligent control for "automatic transfer under full load," optimizing production cycle time. Simultaneously, the design of the vertical pressure application and horizontally rotatable pressing mechanism ensures accurate and controllable pressure direction, enhancing the flexibility and safety of equipment operation. 3. The device can be easily integrated with upstream production lines (such as packaging box extrusion conveyors), achieving seamless automated flow from forming to pressurization. This not only improves the overall production line efficiency but also reduces potential damage to the packaging boxes caused by intermediate processes, demonstrating the advantages of modular integration.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0026] Example 1 A packaging box pressure device, as described above Figure 1 The device includes a receiving component 1, a rotating adjustment mechanism 2, and a pressing mechanism 3. The rotating adjustment mechanism 2 is provided with at least two pressing stations evenly distributed along its rotation direction. Each pressing station is provided with a receiving component 1, which is used to receive and load packaging boxes. The pressing mechanism 3 is correspondingly located above one of the stations of the rotating adjustment mechanism 2. The pressing mechanism 3 includes a pressing plate 31 for applying pressure to the packaging box in the receiving component 1 located below it. This arrangement allows multiple packaging boxes to be prepared for pressing at the same time, and the packaging boxes can be sequentially moved to the pressing mechanism 3 for pressing, which improves the pressing efficiency, ensures the pressing time, and thus improves the adhesive strength of the packaging boxes.

[0027] Specifically, the receiving component 1 includes a support plate 11 and a support box 12. The support box 12 is fixedly mounted on the support plate 11, and the support plate 11 is detachably connected to the rotating adjustment mechanism 2. The packaging box is placed inside the support box 12. The support plate 11 is usually made of metal, such as steel plate, which has good strength and stability and can bear the weight of the support box 12 and the packaging box. Of course, high-strength plastic material can also be used to reduce the overall weight. At the same time, the bottom structure of the support plate 11 has some special features. Two slots are opened at the bottom of the support plate 11, which run from one end to the other, corresponding exactly to the size of the forklift forks, so that the forklift can insert from the slots at the bottom and then lift and unload. The support box 12 is generally a square structure, and its internal space dimensions are designed according to the size of common packaging boxes. The packaging boxes are generally unopened plate structures. After production, they will be placed inside the support box 12 for stacking. Therefore, the internal height of the support box 12 also needs to be deep enough. The carrier box 12 can be made of metal or plastic with a smooth surface for easy placement and removal of the packaging box. The carrier box 12 is fixed to the carrier plate 11 by welding or bolting to ensure a firm connection between the two.

[0028] Furthermore, each pressure application station on the rotary adjustment mechanism 2 is equipped with a limit component 4. The limit component 4 is used to restrict the horizontal movement of the support plate 11 relative to the rotary adjustment mechanism 2. The limit component 4 can be a limit block, typically made of rubber or plastic, installed on the rotary adjustment mechanism 2, and in contact with the edge of the support plate 11 to provide a limiting function. Alternatively, it can be a limit groove, in which the edge of the support plate 11 is embedded to achieve horizontal limitation. This ensures that the support plate 11 is accurately positioned during rotation, guaranteeing smooth subsequent pressure application operations.

[0029] Furthermore, the rotary adjustment mechanism 2 includes a conveying disc 21 and a rotary power component 22. A support plate 11 is detachably mounted on the conveying disc 21 and positioned by a limiting component 4. The rotary power component 22 is driven by the conveying disc 21 to drive its rotation. The conveying disc 21 is generally a circular metal disc with a flat surface. The support plate 11 can be mounted on the conveying disc 21 using bolts or clips. The rotary power component 22 can be a motor, with its output shaft connected to the central shaft of the conveying disc 21. The rotation of the motor drives the conveying disc 21 to rotate. Motors offer advantages such as stable speed and convenient control. Alternatively, a hydraulic motor can be used as the rotary power component 22, as hydraulic motors have higher torque and can adapt to different workloads.

[0030] Furthermore, a pressure detection component is provided between the support plate 11 and the support box 12 to detect the downward pressure transmitted from the support box 12 to the support plate 11. The pressure detection component can be a pressure sensor, such as a strain gauge pressure sensor, which measures pressure by detecting the deformation of the support plate 11. It can also be a piezoresistive pressure sensor, which uses the piezoresistive effect to detect pressure. The pressure detection component is electrically connected to the rotating power component 22. When the weight of the packaging box loaded in the support box 12 causes the pressure detected by the pressure detection component to reach a preset loading threshold, the rotating power component 22 drives the rotating adjustment mechanism 2 to rotate, moving the support box 12 under the pressing plate 31. This enables automated operation and improves production efficiency.

[0031] Furthermore, the pressing mechanism 3 also includes a first driving member 32, which is vertically arranged with its output end facing downwards. The pressing plate 31 is fixedly installed on the output end of the first driving member 32. The first driving member 32 can be a cylinder, with the piston rod of the cylinder serving as the output end. Compressed air drives the piston rod to move up and down, thereby driving the pressing plate 31 to apply pressure to the packaging box. Alternatively, it can be an electric push rod, which has the advantages of high precision and smooth operation.

[0032] Furthermore, the pressing mechanism 3 also includes a support column 34 and a second driving member 33. The first driving member 32 is disposed on the top of the support column 34, and the second driving member 33 is connected to the support column 34 for driving the support column 34, together with the first driving member 32 and the pressing plate 31, to rotate horizontally as a whole. The support column 34 is generally a metal column with good support strength. The second driving member 33 can be a motor, which drives the support column 34 to rotate through gear transmission or belt transmission, so that the pressing plate 31 can be adjusted to adapt to different pressing positions.

[0033] Optionally, the rotating power component 22 of the rotary adjustment mechanism 2 adopts a chain drive. Specifically, the rotating power component 22 is a motor, with a drive sprocket mounted on the motor's output shaft and a driven sprocket mounted on the edge of the conveyor disc 21. The drive sprocket and the driven sprocket are connected by a chain. When the motor rotates, the drive sprocket drives the chain to rotate, and the chain in turn drives the driven sprocket to rotate, thereby realizing the rotation of the conveyor disc 21. This chain drive method has the advantages of smooth transmission and high load-bearing capacity, and can adapt to long-term continuous operation.

[0034] The chain-driven rotary adjustment mechanism 2 ensures the rotation of the conveyor disc 21 while improving the stability and reliability of the transmission, reducing the probability of failure, and further enhancing the working efficiency and service life of the packaging box pressure device. Compared with the traditional rotation method, it has better practicality and economy.

[0035] After the packaging box is pressed and formed in one go, the adhesion of the part will be imperfect and the effect will be poor. Therefore, the packaging box will enter the carrier box 12 at the discharge port and then be stacked continuously. Since the size of the carrier box 12 is the same as the size of the packaging box, the packaging boxes will be aligned vertically when stacked. When the packaging boxes are stacked to a certain weight, the pressure detection component will measure the weight of the packaging box and then feed the signal back to the rotating power component 22. The rotating power component 22 drives the conveying disc 21 to rotate.

[0036] The conveyor disc 21 has at least three stations: a receiving area for receiving packaging boxes, a pressing area for secondary pressing, and multiple unloading areas. When the carrier box 12 rotates to the receiving area, it loads and receives packaging boxes. Then, it rotates and moves to the next pressing area. When the rotation stops, the pressing plate 31, driven by the first drive component 32, presses down on the packaging boxes inside the carrier box 12. After the carrier box 12 in the previous receiving area is full, the pressing plate 31 rises, and the carrier box 12 in the pressing area moves to the unloading area. Workers can use a forklift to insert the forks into the grooves at the bottom of the carrier plate 11, then lift the carrier plate 11 and the carrier box 12 away from the limiting component 4. The worker then places the empty carrier box 12 back to the station to continue the next cycle. In this way, a highly efficient cyclic operation system is constructed. This design allows the loading, positioning, and pressing processes of packaging boxes to be carried out continuously and alternately during rotation, achieving a tight connection of production rhythm. While not affecting overall production efficiency, it can also further improve the adhesion of packaging boxes.

[0037] The implementation principle of this embodiment is as follows: the packaging box pressing device, through multiple pressing stations on the rotary adjustment mechanism 2, enables the simultaneous preparation and sequential pressing of multiple packaging boxes, thereby improving production efficiency. The limiting component 4 ensures the positional accuracy of the carrier plate 11 during rotation, and the pressure detection component enables automated transfer operations. The pressing mechanism 3, through the cooperation of the first driving component 32 and the second driving component 33, can flexibly apply pressure to the packaging boxes. Compared with the single pressing station method in the prior art, this greatly improves the pressing efficiency and adhesion of the packaging boxes, reduces production costs, and improves product quality.

[0038] Example 2 This application provides a packaging box production equipment, referring to... Figure 2 The packaging box includes a packaging box extrusion conveying mechanism 5 and the aforementioned packaging box pressing device. The carrier box 12 located at the loading station of the packaging box pressing device is correspondingly arranged below the output port of the packaging box extrusion conveying mechanism 5, so that the packaging box can fall directly from the packaging box extrusion conveying mechanism 5 into the carrier box 12.

[0039] Furthermore, the packaging box extrusion conveyor 5 can be a double-layered belt conveyor. The conveyor belt not only provides transportation but also extrusion. When the packaging box is conveyed on the belt, the belt further extrudes the box, increasing its adhesion strength. However, to improve the adhesion of the packaging box, a single packaging box extrusion conveyor 5 is insufficient. To minimize the footprint and further enhance adhesion without affecting production efficiency, a packaging box pressure device provides secondary pressure, working in conjunction with the packaging box extrusion conveyor 5 to improve the adhesion of the packaging box.

[0040] After the packaging boxes are produced and glued into flat shapes, they enter the packaging box extrusion conveyor 5 for the first pressure application. After the flat packaging boxes come out from the gap between the two belts, the flat packaging boxes will fall into the carrier box 12 below the output port due to their own weight. Subsequently, the packaging boxes are continuously stacked in the carrier box 12. After reaching a certain weight, they rotate to the pressing mechanism 3 for a second pressure application, which further improves the bonding efficiency.

[0041] The implementation principle of this embodiment is as follows: This packaging box production equipment combines the packaging box extrusion conveyor mechanism 5 and the packaging box pressing device to realize a continuous production process from extrusion to pressing. The packaging box can fall directly from the extrusion conveyor mechanism into the carrying box 12, reducing manual operation and improving the automation and efficiency of production. At the same time, the packaging box is pressed by the packaging box pressing device, which improves the adhesion of the packaging box and ensures product quality. Compared with traditional production methods, it has higher production efficiency and better product quality.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
