Description

Technical Field

[0001] This utility model relates to the field of carton printing machine technology, and more specifically, to a feeding mechanism for a carton printing machine. Background Technology

[0002] Cardboard boxes are a common packaging container widely used in logistics, e-commerce, food, and many other industries, offering advantages such as low cost and ease of transportation and storage. Cardboard boxes come in a variety of styles, with common ones including rectangular and cubic boxes. There are also less common irregularly shaped boxes, such as pentagonal boxes used for packaging specific shapes of handicrafts or high-end gifts. Their unique shape better fits the product's contours, providing customized packaging solutions while also enhancing aesthetics and uniqueness when displayed.

[0003] However, existing carton printing machines' feeding mechanisms are mainly adapted to common rectangular cartons. For non-rectangular cartons such as pentagons, there is a lack of specially designed fixing devices. Ordinary clamps cannot tightly and stably hold pentagonal cartons, causing the cartons to easily shift or tilt during feeding, affecting the accuracy and quality of subsequent printing. Therefore, we propose a new feeding mechanism for carton printing machines. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a feeding mechanism for a carton printing machine. This solves the technical problem that the existing feeding mechanism for carton printing machines is difficult to effectively fix special-shaped cartons, which leads to the cartons being prone to displacement and skewing during the feeding process, affecting the accuracy and quality of subsequent printing.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a feeding mechanism for a carton printing machine, including a base plate, a carton printing machine body is provided at one end of the upper surface of the base plate, a lifting mechanism is provided at the other end of the upper surface of the base plate, a platform is movably arranged inside the lifting mechanism, a conveying mechanism is arranged on both sides inside the platform, and a clamping mechanism is arranged in the middle inside the platform.

[0006] The clamping mechanism includes a cylinder fixed inside the platform. The output end of the cylinder is connected to a clamping block. The clamping block has a clamping opening on its side and a notch on its lower surface. A roller is rotatably installed inside the notch.

[0007] Preferably, the lifting mechanism includes a frame, with a threaded sleeve arranged in the middle inside the frame, a lead screw inserted into the threaded sleeve, and the threaded sleeve connected to both sides of the outer wall of the platform. One end of the lead screw is connected to the output end of the drive motor A.

[0008] Preferably, the frame has sliding sleeves arranged on both sides inside, and sliding rods are inserted into the sliding sleeves, which are connected to the outer walls of the platform.

[0009] Preferably, a baffle is fixed to the front end of the platform, and a slot is opened through the lower end of the baffle.

[0010] Preferably, the transfer mechanism includes a shaft rotatably mounted in the platform and a drive motor B fixed in the platform. Rollers are fixed on the shaft, and the drive motor B is connected to the shaft via a gear set.

[0011] Preferably, the gear set includes a half gear fixed to the output end of the drive motor B and a driven gear fixed to the shaft. The teeth of the half gear are distributed at half intervals on the circumference, and the half gear meshes with the driven gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the design of a cylinder and clamping block mechanism, enables the pentagonal cardboard board placed on the platform to be clamped and fixed, realizing the clamping of non-rectangular cardboard boards. It solves the problem that ordinary clamping blocks are difficult to clamp pentagonal cardboard boards tightly and stably. The clamping opening adopts the same shape as the side of the pentagonal cardboard board. When the distance between the two clamping blocks is shortened, the pentagonal cardboard board placed between them can be clamped into the inside, improving the clamping stability and avoiding displacement, skewing and other situations during feeding.

[0014] 2. This utility model, through the design of a lead screw and threaded sleeve structure, enables the platform to move up and down within the frame due to threaded engagement, indirectly feeding the cardboard boxes stacked on the platform to the inlet of the printing machine body at a higher position. The installation of drive motor A allows the lead screw to rotate actively, achieving the effect of power output. Through the design of a sliding sleeve and sliding rod structure, when the lead screw engages with the threaded sleeve to indirectly move the platform up and down, it stabilizes both sides of the platform, achieving a stable lifting and moving effect.

[0015] 3. This utility model designs rollers to allow cardboard boxes placed on a platform to be moved into the feed inlet of the cardboard printing machine. The rollers rotate within the platform via the cooperation of the drive motor B and the shaft, providing power output. The design of a half-gear and driven gear structure allows the continuous power output of the drive motor B to be converted into intermittent power output. When one half of the teeth on the half-gear meshes with the driven gear, the driven gear rotates the roller, thus moving the cardboard box placed on the platform surface into the feed inlet of the cardboard printing machine. When the other half of the half-gear, without teeth, rotates to the driven gear, the driven gear is not engaged and therefore does not rotate, preventing the roller from rotating. This intermittent feeding of cardboard boxes into the feed inlet of the cardboard printing machine ensures printing stability. Attached Figure Description

[0026] like Figures 1 to 8 As shown, the present invention relates to a feeding mechanism for a carton printing machine, including a base plate 1, a carton printing machine body 2 at one end of the upper surface of the base plate 1, a lifting mechanism 3 at the other end of the upper surface of the base plate 1, a platform 4 movably arranged inside the lifting mechanism 3, a transfer mechanism 5 arranged on both sides inside the platform 4, and a clamping mechanism 6 arranged in the middle inside the platform 4.

[0027] The clamping mechanism 6 includes a cylinder 601 fixed in the platform 4. The output end of the cylinder 601 is connected to a clamping block 602. The clamping block 602 has a clamping opening 603 on its side and a recess 604 on its lower surface. A roller 605 is rotatably installed in the recess 604. This invention, through the design of cylinder 601 and clamping block 602 mechanism, enables the pentagonal cardboard board 9 placed on platform 4 to be clamped and fixed, achieving the clamping of non-rectangular cardboard board 9. This solves the problem that ordinary clamping blocks are difficult to clamp pentagonal cardboard board 9 tightly and stably. The clamping opening 603 adopts the same shape as the side of the pentagonal cardboard board 9. When the distance between the two clamping blocks 602 is shortened, the pentagonal cardboard board 9 placed between them can be clamped into its interior, improving clamping stability and avoiding displacement or skewing during feeding. The opening of the notch 604 allows the roller 605 to be hidden inside. The installation of the roller 605 allows cylinder 601 to support the lower two sides of the clamping block 602 when moving it, stabilizing cylinder 601 as it moves the clamping block 602 on the surface of platform 4.

[0028] In an embodiment of this utility model, the lifting mechanism 3 includes a frame 301, with a threaded sleeve 302 arranged in the middle inside the frame 301. A lead screw 303 is inserted into the threaded sleeve 302, and the threaded sleeve 302 is connected to both sides of the outer wall of the platform 4. One end of the lead screw 303 is connected to the output end of the drive motor A304. By designing the structure of the lead screw 303 and the threaded sleeve 302, this utility model allows the platform 4 to move up and down within the frame 301 due to threaded engagement, indirectly conveying the cardboard 9 stacked on the platform 4 to the inlet of the printing machine body 2 at a higher position. The installation of the drive motor A304 allows the lead screw 303 to rotate actively, achieving the effect of power output.

[0029] In this embodiment of the invention, sliding sleeves 305 are arranged on both sides inside the frame 301, and sliding rods 306 are inserted into the sliding sleeves 305. The sliding sleeves 305 are connected to both sides of the outer wall of the platform 4. By designing the structure of the sliding sleeves 305 and the sliding rods 306, this invention stabilizes both sides of the platform 4 when the lead screw 303 engages with the lead sleeve 302 to indirectly raise and lower the platform 4, thus achieving a stable raising and lowering movement effect of the platform 4.

[0030] In this embodiment of the invention, a baffle 7 is fixed to the front end of the platform 4, and a slot 8 is provided through the lower end of the baffle 7. The installation of the baffle 7 in this invention can block the front end of the cardboard board 9 placed on the platform 4, preventing it from falling off the platform 4, and also has the effect of limiting and aligning the cardboard board 9. The slot 8 allows the cardboard board 9 conveyed by the roller 503 to be transferred through this slot to the feed port of the carton printing machine body 2.

[0031] In an embodiment of this invention, the transfer mechanism 5 includes a shaft 501 rotatably mounted within a platform 4 and a drive motor B502 fixed within the platform 4. A roller 503 is fixed to the shaft 501, and the drive motor B502 is connected to the shaft 501 via a gear set 504. This invention, by designing the roller 503, allows the cardboard board 9 placed on the platform 4 to be transferred to the feed inlet of the cardboard printing machine body 2. Furthermore, the cooperation between the drive motor B502 and the shaft 501 enables the roller 503 to rotate within the platform 4, thus providing power output.

[0032] In an embodiment of this utility model, the gear set 504 includes a half gear 5041 fixed to the output end of the drive motor B502 and a driven gear 5042 fixed to the shaft 501. The teeth of the half gear 5041 are distributed at half intervals on the circumference, and the half gear 5041 meshes with the driven gear 5042. This invention, through the design of a half-gear 5041 and a driven gear 5042, allows the continuous power output of the drive motor B502 to be converted into intermittent power output. When one half of the teeth on the half-gear 5041 meshes with the driven gear 5042, the driven gear 5042 will rotate with the roller 503, thereby moving the carton board 9 placed on the surface of the platform 4 into the feed inlet of the carton printing machine body 2. When the other half of the half-gear 5041, which has no teeth, rotates to the side of the driven gear 5042, the driven gear 5042 is not meshed and therefore does not rotate, and will not rotate with the roller 503. In this way, the carton board 9 can be intermittently fed into the feed inlet of the carton printing machine body 2, ensuring printing stability.

[0033] Working Principle: This embodiment provides a feeding mechanism for a carton printing machine. During use, the operator must first connect an external power supply to this invention and control its operation via the control panel. The operator stacks the carton boards 9 to be printed on the platform 4, placing them between two clamping blocks 602. After placement, the operator controls the cylinder 601 to move the clamping blocks 602 connected to the output end. The two clamping blocks 602 then shorten the distance between them, clamping and fixing the carton boards 9 between them. After the carton boards 9 are clamped and fixed, the operator controls the drive motor A304 to rotate the lead screw 303 connected to the output end. The lead screw 303 engages and moves the thread sleeve 302, which lifts the platform 4 to the inlet of the printing machine body 2. Upon reaching this position, the drive motor A304 stops running, and the drive motor B502 starts. The drive motor B502 rotates the half gear 5041 fixed at the output end. The half gear 5041 meshes with the driven gear 5042 on the surface. Because the half gear 5041 only has half of the teeth, the meshing driven gear 5042 will rotate intermittently. The intermittently rotating driven gear 5042 will drive the shaft 501 to rotate. After the shaft 501 rotates, the roller 503 fixed on its surface will also rotate. The intermittently rotating roller 503 will transfer the carton board 9 placed on the surface of the platform 4 through the gap between the clamping block 602 and the platform 4 and the slot 8 to the feed port of the carton printing machine body 2.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
