DETAILED DESCRIPTION

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0038] The following is combined with Figures 1 to 4 And specific embodiments, the present invention is described in detail:

[0039] like Figure 1-4 As shown, the present invention provides a double-station running nail box machine head, which includes a machine head wall panel frame 1, a machine head eccentric lifting device 2 installed on the machine head wall panel frame 1, a first nail box nailing device 4 and a second nail box nailing device 3, and a first nailing base 6 and a second nailing base 5 respectively installed on the swing ends of the first nail box nailing device 4 and the second nail box nailing device 3.

[0040] Among them, the second stapling base 5 includes a first bottom plate portion 50 and a first connecting portion 51 arranged at the entrance end of the first bottom plate portion 50, and the first connecting portion 51 is fixedly connected to the swing end of the second nail box stapling device 3; a through groove 501 is opened in the middle of the first bottom plate portion 50, and the through groove 501 is in the shape of a long strip.

[0041] The first stapling base 6 is arranged in the through groove 501 of the first bottom plate 50. The stapling end of the corresponding first nail box stapling device 4 is arranged above the second bottom plate 60; the stapling end of the second nail box stapling device 3 is arranged above the first bottom plate 50, and is located on the side of the stapling end of the first nail box stapling device 4 away from the second connecting portion 61, so as to realize the stapling operation.

[0042] In the double-station running stapling machine head of the present invention, since the first stapling base 6 is sleeved in the second stapling base 5, the cardboard to be processed is transferred from the previous process to the entrance end of the second stapling base 5, that is, the first connecting portion 51 of the second stapling base 5, and is transported forward in sequence. Before stapling, it is transported to the first stapling base 6, and the first stapling box stapling device 4 and the first stapling base 6 are swung simultaneously to achieve the first stapling of the cardboard, and then it is transmitted to the first bottom plate portion 50 corresponding to the stapling end of the second stapling box stapling device 3, and the second stapling box stapling device 3 and the second stapling base 5 are swung simultaneously to achieve the second stapling of the cardboard.

[0043] The double-station running box nailing machine head can perform box nailing operations in sequence and continuously by providing a first box nailing device and a second box nailing device, thereby realizing double-station operation and significantly improving work efficiency.

[0044] The layout in which the first stapling base 6 is arranged inside the second stapling base 5 eliminates the need for manual transfer in the stapling process, reduces intermediate links, and can achieve a continuous and automated stapling process, reducing labor costs; at the same time, continuous automated stapling avoids position deviations and uneven force that may be caused by manual operation, ensuring the accuracy and consistency of stapling, thereby improving the stapling quality of the product.

[0045] In addition, the design that the first stapling base 6 is sleeved in the second stapling base 5 makes full use of the limited space, makes the entire head structure more compact, and saves the space required for equipment installation.

[0046] Further, such as Figure 4 As shown, the first stapling base 6 includes a second bottom plate portion 60, and a second connecting portion 61 arranged at the entrance end of the second bottom plate portion 60; the second connecting portion 61 is fixedly connected to the swing end of the first nail box stapling device 4, and is located close to the first connecting portion 51; and the second connecting portion 61 is arranged in parallel with the first connecting portion 51.

[0047] The second bottom plate portion 60 is disposed in the through groove 501 of the first bottom plate portion 50 , and an upper surface of the second bottom plate portion 60 is flush with an upper surface of the first bottom plate portion 50 .

[0048] Specifically, the first connection portion 51 and the second connection portion 61 are both U-shaped connection portions, and both include a flat portion 511, a transition portion 512, and a vertical portion 513. The flat portion 511 is arranged in parallel with the first bottom plate portion 50 or the second bottom plate portion 61, and the flat portion 511 is fixedly connected to the first bottom plate portion 50 or the second bottom plate portion 60 through the transition portion 512, and the U-shaped connection portion is formed by the first bottom plate portion 50 or the second bottom plate portion 60, the transition portion 512, and the flat portion 511. In this embodiment, the transition portion 512 is an arc-shaped structure.

[0049] During the transportation of the cardboard to be processed, it needs to be sleeved at the U-shaped connection between the first connection part 51 and the second connection part 61. As described in the background technology, if the first nail head and the second nail head are simply arranged side by side, then after the first nail head completes the first stapling of the cardboard, since the cardboard has been nailed, it cannot be smoothly sleeved and slid forward to the second nail head. In the present application, since the first stapling base 6 is sleeved in the through groove 501 of the second stapling base 5, the cardboard to be processed can pass through the first connection part 51, the second connection part 61, the outlet end of the second bottom plate part 60, and the outlet end of the first bottom plate part 50 in sequence. That is, the unstapled cardboard first passes through the second connection part 61, and then the first nail box nailing device 4 completes the first stapling, and then the second nail box nailing device 3 performs the second stapling, which effectively avoids the interference of the second connection part 61 with the cardboard after the first stapling.

[0050] At the same time, the cardboard sleeve is transmitted at the U-shaped connection part, which enhances the guiding and positioning effect on the cardboard transportation, ensures the stability and accuracy of the cardboard during the transmission process, effectively avoids problems such as offset and misalignment, and lays the foundation for high-quality stapling operations.

[0051] In addition, this structural design is relatively simple in manufacturing and installation, which reduces production costs and maintenance difficulties, and also improves the operability and reliability of the equipment.

[0052] More specifically, a vertical portion 513 is also provided on the flat plate portion 511, which is fixedly connected to the swinging end of the first nail box nailing device 4 or the second nail box nailing device 3 through the vertical portion 513, and the first nailing base 6 and the second nailing base 5 are fixedly installed on the swinging ends of the first nail box nailing device 4 and the second nail box nailing device 3 respectively.

[0053] Further, such as Figure 1 , 2 As shown, the head wall panel frame 1 includes a left head wall panel 10, a right head wall panel 11 and a head support plate 12. The left head wall panel 10 and the right head wall panel 11 are arranged opposite to each other and are respectively arranged on both sides of the head support plate 12. The left head wall panel 10 and the right head wall panel 11 are arranged opposite to each other and connected by the head support plate 12, forming a stable frame structure that can withstand various forces and vibrations during operation and ensure the stability of the head operation. At the same time, the wall panels on both sides and the middle support plate divide a suitable space, which is conducive to the reasonable arrangement of the components inside the head and improves the space utilization rate.

[0054] The shapes of the left head wallboard 10 and the right head wallboard 11 can be various, such as rectangular plates, polygonal plates, etc., which are not specifically limited in the present invention. However, preferably, as shown in this embodiment, the left head wallboard 10 and the right head wallboard 11 are both T-shaped, which matches the overall structural layout of the double-station running nail box head, saving material costs.

[0055] Further, such as Figure 1 , 2 As shown, the machine head eccentric lifting device 2 is installed between the left machine head wall panel 10 and the right machine head wall panel 11, and is located on the top of the left machine head wall panel 10 and the right machine head wall panel 11. The machine head eccentric lifting device 2 is used to adjust the height of the entire nail box machine head. The left machine head wall panel 10 and the right machine head wall panel 11 are used as the base of the machine head eccentric lifting device 2, and the internal space of the machine head wall panel frame 1 is fully utilized to make the overall structure more compact. It should be noted that the machine head eccentric lifting device 2 in the present invention is used to adjust the height of the entire nail box machine head, and its specific structure is not limited. Those skilled in the art can refer to the existing design, which all falls within the protection scope of the present invention.

[0056] Further, such as Figure 1 , 2 As shown, the first nail box nailing device 4 and the second nail box nailing device 3 both include:

[0057] A power mechanism 30, which provides power for the action of the nailing machine head and is installed on the outside of the left machine head wallboard 10 or the right machine head wallboard 11;

[0058] The nail box nailing mechanism 31 is installed on the head wall panel frame 1 and is connected to the power mechanism 30 in transmission. Under the drive of the power mechanism 30, the nail box nailing mechanism 31 is activated to realize the nail box operation and the like.

[0059] The power mechanism 30 is installed on the outside of the head wallboard, which does not occupy the key space inside the head, making the internal layout of the head more compact, which is conducive to the installation and operation of other components. At the same time, the power mechanism 30 is located on the outside of the wallboard, which is easy to observe and contact, convenient for daily maintenance, maintenance and troubleshooting, and reduces maintenance time and cost. It should be noted that the power mechanism 30 is not specifically limited in the present invention, and can be designed by those skilled in the art with reference to the prior art, as long as it can provide power for the nail box head.

[0060] Specifically, Figure 1 , 2 As shown, the nail box nailing mechanism 31 includes:

[0061] The swing assembly 311 is the swing end of the first nail box nailing device 4 and the second nail box nailing device 3, and is installed at a position between the left head wallboard 10 and the right head wallboard 11 of the head wallboard frame 1, and the swing assembly 311 is transmission-connected with the power mechanism 30, and the swing assembly 311 is driven by the power mechanism 30 to swing; it should be noted that the swing assembly 311 of the first nail box nailing device 4 is fixedly connected to the second connecting portion 61 of the first nail base 6, and the swing assembly 311 of the second nail box nailing device 3 is fixedly connected to the first connecting portion 51 of the first nail base 5, so as to realize the fixed connection between the nail base and the swing end of the nail box nailing device;

[0062] The nail box nailing execution component 312 is the nailing end of the first nail box nailing device 4 and the second nail box nailing device 3, and is connected to the power mechanism 30 in transmission, that is, the power mechanism 30 synchronously drives the swinging component 311 and the nail box nailing execution component 312 to move, and swings to realize the nail box movement. The power mechanism 30 transmits power to the swinging component 311 and the nail box nailing execution component 312, drives the nail box nailing execution component 312 and the swinging component 311 to swing back and forth to realize the nail box movement; it should be noted that the nailing end of the nail box nailing execution component 312 of the first nail box nailing device 4 is arranged above the second bottom plate portion 60; the nailing end of the nail box nailing execution component 312 of the second nail box nailing device 3 is arranged above the first bottom plate portion 50, and is located on the side of the nail box nailing execution component 312 of the first nail box nailing device 4 away from the second connecting portion 61 to realize the nailing operation.

[0063] The wire feeding assembly 313 is fixedly mounted on the outer side of the head support plate 12 of the head wall panel frame 1, so as to facilitate the repair, maintenance and upkeep of the wire feeding assembly 313 after the nail box head is removed; the input end of the wire feeding assembly 313 is transmission-connected to the power mechanism 30, and the output end of the wire feeding assembly 313 is connected to the nail box nailing execution assembly 312, so as to synchronously provide materials to the nail box nailing execution assembly 312 for nail box operation.

[0064] When working, the power mechanism 30 is started to drive the wire feeding assembly 313 to provide materials to the nail box nailing execution assembly 312 for nail box operation; the nail box nailing execution assembly 312 and the swing assembly 311 are driven synchronously, and the first nailing base 6 or the second nailing base 5 fixedly installed on the swing assembly 311 are driven to swing at the same time to execute the nail box operation. The connection between the wire feeding assembly 313, the power mechanism 30 and the nail box nailing execution assembly 312 realizes the synchronous coordination of material supply and nail box action, thereby improving work efficiency and nail box quality. At the same time, each component is independent of each other and works in coordination. When a component fails, it will not affect the basic functions of other components, which is convenient for troubleshooting and local repair.

[0065] Correspondingly, in the present invention, the specific structure of the nail box nailing execution component 312 and the swing component 311 is not limited, as long as the transmission and nail box functions can be realized, the design can refer to the existing technology, and the present invention does not make specific limitations. Similarly, the corresponding wire feeding component 313 can adopt a combination design of a bevel gear set + a wire feeding gear as shown in this embodiment to realize the wire feeding process and provide materials for the nail box nailing execution component 312. It can also refer to the existing technology design, and the present invention does not make specific limitations.
