Technical Field

[0001] This application relates to the field of packaging box creasing equipment technology, and more specifically to an easily adjustable creasing device for packaging box creasing. Background Technology

[0002] In the packaging box production process, creasing is a crucial step, and its quality directly affects the forming effect and performance of the packaging box. Traditional packaging box creasing devices have several shortcomings. On the one hand, adjusting the creasing depth and position often requires complex operations and tools, consuming a lot of time and effort, resulting in low production efficiency. On the other hand, it is difficult to achieve automated continuous operation, and manual operation is prone to errors, affecting creasing accuracy.

[0003] Therefore, there is an urgent need for a device that can conveniently and quickly adjust the depth and position of the indentation and achieve automated and efficient indentation operations, so as to improve the quality and efficiency of packaging box production and meet the growing market demand. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issues of inconvenient adjustment of creasing depth and position during the creasing process of packaging boxes, as well as the difficulty in achieving automated and efficient creasing operations.

[0005] To achieve the above objectives, the technical solution adopted in this application is: an easily adjustable creasing device for creasing packaging boxes, including a conveying component, a lifting component, and a creasing adjustment component.

[0006] The lifting assembly includes a mounting plate, a lifting rod, a cylinder, and a mounting rod. The mounting plate is fixedly mounted on the conveying assembly. The mounting plate is provided with a sliding groove, on which the lifting rod slides vertically. Two mounting rods are fixedly mounted on the lifting rod. The end of the lifting rod away from the mounting rod is fixedly connected to the output end of the cylinder. The cylinder is fixedly mounted on the mounting plate.

[0007] The indentation adjustment assembly includes an adjustment plate, two threaded rods, a connecting frame, and rollers. The two ends of the adjustment plate slide on the two mounting rods respectively. The adjustment plate is provided with two threaded through holes, and the two threaded rods are respectively threaded onto the threaded through holes. A connecting frame is provided on both threaded rods, and a roller is rotatably mounted on the end of the connecting frame away from the threaded rods.

[0008] Preferably, the indentation adjustment assembly includes a fastener, a rotating shaft, a torsion spring, and a pin. A rotating shaft is fixedly installed at each end of the adjustment plate, and a torsion spring is sleeved at each end of the rotating shaft. A fastener is rotatably installed on each rotating shaft. The two ends of the torsion spring are fixedly connected to the rotating shaft and the fastener, respectively. A through groove is provided on the fastener, and a hole is provided on the adjustment plate. The pin is installed in the hole and includes multiple inserts.

[0009] Preferably, the fastener has an L-shaped structure, the through groove of the fastener is a straight groove, and the end of the straight groove is provided with a protrusion. The pin is provided with a groove, and the protrusion of the fastener and the groove of the pin cooperate to restrict the movement of the pin.

[0010] Preferably, the indentation adjustment assembly includes a drive ring, a gear, and a control ring. Two drive rings are rotatably disposed on the adjustment plate. Multiple protrusions are provided on the end of the drive ring away from the adjustment plate. The control ring is provided with a groove that matches the protrusion. The control ring is slidably disposed on the drive ring. A gear is fixedly disposed on the end of each drive ring near the adjustment plate. The two gears mesh with each other. The drive ring is threadedly connected to the threaded rod.

[0011] Preferably, the L-shaped structure of the fastener forms an I-shaped sliding space with the adjusting plate. This I-shaped sliding space is the same as the I-shaped cross-sectional structure of the mounting rod, and the mounting rod is provided with a through hole that matches the pin.

[0012] The technical solution provided in this application has the following advantages compared with the prior art:

[0013] 1: This application achieves automated and continuous operation of packaging boxes from conveying to creasing through the coordinated work of the conveying component, lifting component and creasing adjustment component, reducing manual intervention and improving production efficiency.

[0014] 2: The indentation adjustment component of this application uses two threaded rods to jointly control the lifting and lowering of the connecting frame and the roller, which can more stably limit the shaking of the connecting frame and the roller, and through the fine adjustment of the thread of the threaded rod, the indentation depth can be precisely controlled to meet the diverse needs of different packaging boxes for indentation depth.

[0015] 3. This application utilizes the cooperation of fasteners, pivots, torsion springs, and pins to achieve quick and stable installation of the indentation adjustment assembly on the mounting rod. The elasticity of the torsion spring ensures tight contact among all components, and the engagement of the pin with the protrusion and groove of the fastener restricts pin movement, preventing wobbling that could affect indentation accuracy.

[0016] 4. This application, through the design of a drive ring, gear, and control ring, allows the two drive rings and threaded rod to rotate synchronously simply by operating the control ring, making it convenient and quick to adjust the indentation depth, simplifying the adjustment process, and improving adjustment efficiency.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The packaging box is indented using an easily adjustable indentation device, which includes a conveying assembly 100, a lifting assembly 200, and an indentation adjustment assembly 300.

[0028] The conveying assembly 100, as a conveying device, is mainly composed of basic components such as conveyor belt, motor, and commutator. All components are uniformly installed on the conveyor frame to form a complete conveying system.

[0029] Its working principle is as follows: The motor acts as the power source, and the transmission direction is adjusted through a commutator, thereby driving the shaft of the conveyor belt to rotate. Driven by the shaft, the conveyor belt runs accordingly, thus realizing the function of conveying the unfolded packaging boxes.

[0030] The specific operation process is as follows: the conveyor belt first smoothly transports the packaging box to be processed to the indentation area where the lifting component 200 is located; when the packaging box reaches the designated position, the indentation adjustment component 300 on the lifting component 200 will perform an indentation operation on it; after the indentation is completed, the packaging box continues to be transported by the conveyor belt and is finally transported to the next process or the designated collection area.

[0031] This device, through the coordinated operation of its various components, enables the continuous operation of packaging boxes from conveying and creasing to output, providing a fundamental guarantee for automated production.

[0032] The lifting assembly 200 includes a mounting plate 201, a lifting rod 202, a cylinder 203, and a mounting rod 204. The mounting plate 201 is fixedly mounted on the conveying assembly 100. The mounting plate 201 is provided with a sliding groove, on which the lifting rod 202 slides vertically. Two mounting rods 204 are fixedly mounted on the lifting rod 202. The end of the lifting rod 202 away from the mounting rod 204 is fixedly connected to the output end of the cylinder 203. The cylinder 203 is fixedly mounted on the mounting plate 201.

[0033] Specifically, both the lifting assembly 200 and the indentation adjustment assembly 300 are fixedly mounted on the conveyor frame of the conveyor assembly 100 via the mounting plate 201. A cylinder 203 is located on each side of the mounting plate 201. The two cylinders 203 work together to control the lifting rod 202 to slide up and down on the mounting plate 201. This, in turn, causes the lower ends of the two lifting rods 202 to drive the two ends of the two mounting rods 204 to slide vertically on the mounting plate 201, thus allowing the indentation adjustment assembly 300 to move closer to and further away from the packaging box—indentation is performed when closer, and the packaging box is transported by the conveyor belt when further away. It is worth noting that the control of the cylinders 203 and the motor of the conveyor assembly 100 are linked through an electronic control unit to ensure a coordinated and orderly operation.

[0034] The indentation adjustment assembly 300 includes an adjustment plate 301, two threaded rods 308, a connecting frame 309, and a roller 310. The two ends of the adjustment plate 301 slide on the two mounting rods 204 respectively. The adjustment plate 301 is provided with two threaded through holes, and the two threaded rods 308 are respectively threaded onto the threaded through holes. The two threaded rods 308 are provided with a connecting frame 309. The roller 310 is rotatably mounted on the end of the connecting frame 309 away from the threaded rods 308.

[0035] The adjusting plate 301 controls the lifting and lowering of the connecting frame 309 and the roller 310 through the threads of two threaded rods 308. The two threaded rods 308 limit the swaying of the connecting frame 309 and the roller 310, avoiding the instability of a single threaded rod 308. Furthermore, the fine adjustment of the threads of the threaded rods 308 can adapt to the needs of different indentation depths.

[0036] When the conveyor belt of the conveyor assembly 100 moves the packaging box to the area where the mounting plate 201 is located, the cylinder 203 synchronously controls the mounting rod 204 to move closer to the packaging box via the lifting rod 202, so that the roller 310 in the indentation adjustment assembly 300 contacts the packaging box. The mounting rod 204 moves a consistent distance each time. The operator can adjust the distance between the connecting frame 309 and the adjusting plate 301 by rotating the two threaded rods 308, thereby controlling the contact force between the roller 310 and the packaging box, i.e., the indentation depth.

[0037] As the conveyor belt of the conveyor assembly 100 continues to move the packaging box, the packaging box drives the roller 310 to rotate synchronously, thereby achieving continuous creasing operation. After creasing is completed, the cylinder 203 controls the creasing adjustment assembly 300 to reset, causing the roller 310 to disengage from the packaging box. By continuously conveying the packaging box through the conveyor assembly 100 and using the cylinder 203 to intermittently control the roller 310 of the creasing adjustment assembly 300 to contact or move away from the packaging box, automated creasing operation can be achieved.

[0038] The indentation adjustment assembly 300 includes a fastener 302, a rotating shaft 303, a torsion spring 304, and a pin 305. A rotating shaft 303 is fixedly installed at each end of the adjustment plate 301. A torsion spring 304 is sleeved at each end of the rotating shaft 303. A fastener 302 is rotatably installed on each rotating shaft 303. The two ends of the torsion spring 304 are fixedly connected to the rotating shaft 303 and the fastener 302, respectively. A through groove is provided on the fastener 302. A hole is provided on the adjustment plate 301. The pin 305 is installed in the hole. The pin 305 includes multiple inserts.

[0039] Specifically, the L-shaped structure of fastener 302 consists of a rotating part and a limiting part (such as...). Figure 4 (As shown). The rotating part includes two vertical rods, and the limiting part is a block structure that matches the shape of the lower end face of the mounting rod 204. Therefore, a single fastener 302 unit consists of two vertical rods and a block component.

[0040] The indentation adjustment assembly 300 is installed on the mounting rod 204 via the cooperation of the fastener 302 and the pin 305. The specific operation is as follows: The fastener 302 is rotated on the rotating shaft 303, causing the torsion spring 304 to twist, switching the limiting part of the fastener 302 from a horizontal to a vertical position. This allows the adjusting plate 301 to be placed on the mounting rod 204, ensuring precise alignment of the shapes at both ends of the adjusting plate 301 with the I-shaped structure of the mounting rod 204. The fastener 302 is then released, and under the action of the torsion spring 304, it resets, allowing the limiting part of the fastener 302 to make tight contact with the lower end face of the I-shaped structure of the mounting rod 204. Through the contact between the end structure of the adjusting plate 301 and the limiting part structure of the fastener 302 with the mounting rod 204, coupled with the driving action of the torsion spring 304, tight contact of all components is ensured, ultimately achieving a stable installation of the indentation adjustment assembly 300 on the mounting rod 204. The fastener 302 has an L-shaped structure, and the through groove of the fastener 302 is a straight groove with a protrusion at the end of the straight groove. The pin 305 has a groove, and the protrusion of the fastener 302 cooperates with the groove of the pin 305 to restrict the movement of the pin 305.

[0041] Specifically, after the indentation adjustment assembly 300 is installed on the mounting rod 204, the insert rod on the pin 305 is inserted into the hole of the adjustment plate 301 and the straight groove of the fastener 302. The protrusion on the straight groove of the fastener 302's limiting part inserts into the groove at the lower end of the pin 305, thereby restricting the up-and-down movement of the pin 305. When the pin 305 is inserted into the limiting part of the fastener 302, because the protrusion on the straight groove of the fastener 302's limiting part has a downward slope, the insert rod of the pin 305 pushes the protrusion, causing the pin 305 to rotate on the rotating shaft 303. The protrusion moves away from the pin 305, while the insert rod of the pin 305 slides on the straight groove. When the insert rod of the pin 305 is fully inserted into the limiting part, the groove of the insert rod precisely matches the protrusion, and the fastener 302 resets. The spring force of the torsion spring 304 ensures that the protrusion and the groove of the insert are in close contact, which stabilizes the restriction of the pin 305 and prevents wobbling, thus not affecting the indentation accuracy.

[0042] The indentation adjustment assembly 300 includes a drive ring 306, a gear 307, and a control ring 311. Two drive rings 306 are rotatably mounted on the adjustment plate 301. Multiple protrusions are provided at the end of the drive ring 306 away from the adjustment plate 301. The control ring 311 is provided with a sliding groove that matches the protrusion. The control ring 311 is slidably mounted on the drive ring 306. A gear 307 is fixedly mounted at the end of each drive ring 306 near the adjustment plate 301. The two gears 307 mesh with each other. The drive ring 306 is threadedly connected to the threaded rod 308.

[0043] Specifically, by inserting the control ring 311 into either of the two drive rings 306, the groove of the control ring 311 engages with the protrusion of the drive ring 306, causing the drive ring 306 to rotate on the adjusting plate 301. This, in turn, involves the gear 307 on the drive ring 306 meshing with each other, causing the two drive rings 306, gear 307, and threaded rod 308 to rotate synchronously. Ultimately, this adjusts the distance between the connecting frame 309 and the adjusting plate 301, thus adjusting the indentation depth.

[0044] The L-shaped structure of the fastener 302 and the adjusting plate 301 form an I-shaped sliding space. This I-shaped sliding space is the same as the I-shaped cross-sectional structure of the mounting rod 204. The mounting rod 204 is provided with a through hole that matches the pin 305.

[0045] Specifically, thanks to the I-shaped structure between the adjusting plate 301 and the limiting part of the fastener 302, after the adjusting plate 301 and the fastener 302 are installed on the mounting rod 204, simply pulling out the pin 305 allows the indentation adjustment assembly 300 to move laterally on the mounting rod 204. This design allows workers to flexibly adjust the indentation position at any time, eliminating complex disassembly and assembly steps and greatly improving operational efficiency. Furthermore, the elastic force of the torsion spring 304 effectively prevents the indentation adjustment assembly 300 from detaching from the mounting rod 204 during movement, ensuring the stability of the adjustment process.

[0046] The adjustment steps are as follows: First, control the fastener 302 to rotate a certain angle on the rotating shaft 303 so that the insertion rod of the pin 305 contacts the end of the straight groove of the limiting part of the fastener 302 without a protrusion. This action can release the restriction on the groove of the insertion rod of the pin 305, and then the operator can directly pull out the pin 305, and then freely control the indentation adjustment component 300 to adjust its position on the mounting rod 204.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
