Description

Technical Field

[0001] This utility model relates to the field of feeding system structure for a paper box die-cutting machine, and more specifically, to a feeding device for a sealed paper box die-cutting machine. Background Technology

[0002] Cardboard is folded into packaging boxes in a reasonable way. When the gap between adjacent surfaces of the packaging box is very small, it can be called a sealed packaging box.

[0003] In the field of cardboard die-cutting, traditional feeding devices mostly use a conveyor belt combined with a fixed baffle. The workflow is as follows: the operator places stacked cardboard at the beginning of the conveyor belt, which then feeds the cardboard into the die-cutting machine. However, in practical applications, the following drawbacks have been found: the cardboard is easily misaligned due to edge burrs, electrostatic adsorption, and other factors during stacking. Existing fixed baffles cannot be dynamically adjusted, requiring frequent machine stops for manual adjustments. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a feeding device for a sealed paper box die-cutting machine. The technical problem to be solved by the present invention is that the existing fixed baffle cannot be dynamically adjusted and requires frequent machine stops for manual adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a sealed cardboard box die-cutting machine, comprising a frame assembly located at the inlet end of the die-cutting machine, including two baffles, with a conveyor belt for conveying cardboard placed between the two baffles, the baffles being used to push stacked cardboard from the left and right sides; a vibration assembly comprising a motor, a pushing component, a cam, and a base, the motor electrically connected to the mains power is mounted on the base, the motor and the cam are eccentrically fixedly connected, one end of the pushing component is located on the pushing path of the cam, and the other end is located on the moving path of the baffle, the baffle and the base are elastically slidably connected.

[0006] In a preferred embodiment, the pushing component includes a push plate and a driven plate. The driven plates are respectively attached to both sides of the cam, the driven plates and the corresponding push plates are fixed, and the push plates are slidably connected to the machine base.

[0007] In a preferred embodiment, one pusher plate covers the other pusher plate.

[0008] In a preferred embodiment, the frame assembly further includes a first reinforcing rib, a second reinforcing rib, a base plate, and a feeding port. The base plate is connected to the bottom of the baffle and forms blocking edges at the front and rear edges of the baffle. The feeding port is opened on the front blocking edge. Both the first and second reinforcing ribs are connected to the base plate, and the base plate and the machine base are elastically slidably connected.

[0009] In a preferred embodiment, an obtuse angle is formed between the output angle of the feed port and the processing plane of the die-cutting machine.

[0010] In a preferred embodiment, the frame assembly is provided with a flared assembly, including a top plate, an elastic plate and a buckle. The top plate is connected to the upper part of the baffle, the elastic plate is fixed on the top plate, the top of the elastic plate is connected to the buckle, and the buckle and the bottom plate are connected by a rope.

[0011] In a preferred embodiment, a take-up shaft is rotatably connected to the base plate, one end of the rope and the other end are fixed by a buckle and wound around the take-up shaft, and the take-up shaft and the base plate can be limited in position.

[0012] In a preferred embodiment, the take-up shaft and the base plate are limited by a pin.

[0013] In a preferred embodiment, an angle-adjustable rear guide plate is connected to the rear side of the baffle. The rear guide plate is used to guide the cardboard to move back and forth within the two baffles.

[0014] The technical effects and advantages of this utility model are as follows:

The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0023] Example

[0024] like Figures 1-4 A feeding device for a sealed cardboard box die-cutting machine mainly includes a frame assembly 10, a flaring assembly 20, a vibration assembly 30, and a rear guide plate 40.

[0025] The frame assembly 10 includes a baffle 11, a first reinforcing rib 12, a second reinforcing rib 13, a base plate 14, and a feeding port 15. The baffle 11 can be a ready-made side plate with ventilation holes to reduce wind resistance during the downward movement of the cardboard. The base plate 14 has slots with edges forming blocking edges. The baffle 11 can be inserted into the base plate 14, where the blocking edges prevent the cardboard from accidentally moving out from the front-back direction. The feeding port 15 is located on the blocking edge at the front of the baffle 11. When the bottom layer of stacked cardboard moves to the feeding port 15, the conveyor belt pushes the cardboard out of the feeding port 15 through friction or electrostatic attraction. This process can be repeated to achieve the purpose of outputting cardboard one by one. The base plate 14 is fixed with the first reinforcing rib 12 and the second reinforcing rib 13 to support the flexible deformation generated by the baffle 11.

[0026] It should be noted that the conveyor belt serves two purposes: supporting the cardboard and using friction or electrostatic adsorption to transport the cardboard. This design is existing technology and is not an improvement point of this solution, so it will not be elaborated upon.

[0027] In addition, the conveyor belt rotates intermittently at fixed distances to achieve the processing rhythm of intermittently conveying cardboard.

[0028] Preferably, since the conveyor belt and the cardboard are in direct contact, in order to ensure the conveyor belt's ability to transport the cardboard using friction while also improving the cardboard's positional adjustment capability in the left and right directions, an edge is provided on the conveyor belt, which extends along the left and right directions of the cardboard.

[0029] Preferably, the height of the second reinforcing rib 13 is greater than that of the first reinforcing rib 12. The first reinforcing rib 12 is arranged on both sides of the baffle 11, and the second reinforcing rib 13 is located between the two first reinforcing ribs 12.

[0030] The flaring assembly 20 includes a top plate 21, an elastic plate 22, a buckle 23, and a winding shaft 24. The top plate 21 also has a slot. By utilizing the design of the baffle 11 being able to be inserted into the slot, the top plate 21 can be fitted onto the top of the baffle 11. The elastic plate 22 is fixed on the top plate 21. The elastic plate 22 can be made of metal. The buckle 23 is detachably connected to the elastic plate 22. The winding shaft 24 is rotatably connected to the bottom plate 14. A rope connects the winding shaft 24 and the buckle 23. When the winding shaft 24 is rotated continuously, the rope is wound up. Under the tension of the rope, the top of the elastic plate 22 folds outward to both sides to widen the opening at the top of the baffle 11, making it easier for the cardboard to enter the placement space between the two baffles 11 from above.

[0031] At this time, the elastic plate 22 may drive the baffle 11 to produce flexible deformation, and the setting of the first reinforcing rib 12 and the second reinforcing rib 13 is necessary.

[0032] Preferably, friction damping is provided between the rotating surfaces of the take-up shaft 24, which can limit the accidental rotation of the take-up shaft 24 after manual removal.

[0033] Preferably, the winding shaft 24 and the locking nut are threaded together. When the winding shaft 24 needs to be fixed, the locking nut is used to fix the position of the winding shaft 24 and the base plate 14, which can limit the accidental rotation of the winding shaft 24. The use of the locking nut is existing technology and will not be described in detail.

[0034] Of course, other methods can also be used to manually limit the rotation of the take-up shaft 24, but these will not be elaborated in this embodiment.

[0035] The vibration assembly 30 includes a motor 31, a pushing member 32, a cam 33, and a base 34. The motor 31 is electrically connected to the mains power and is mounted on the base 34. The pushing member 32 includes a push plate 321 and a driven plate 322, with a driven plate 322 fixed on each push plate 321. The base plate 14 is elastically slidably connected to the base 34 on the corresponding side, and the base plate 14 is located on the reciprocating movement path of the corresponding push plate 321.

[0036] For example, the motor 31 is designed between two base plates 14. A cam 33 is eccentrically fixed to the output shaft of the motor 31. A driven plate 322a and a driven plate 322b are attached to the left and right sides of the cam 33. The driven plate 322a is fixed to the push plate 321a, and the driven plate 322b is fixed to the push plate 321b. In this way, when the cam 33 rotates, the push plate 321 and the driven plate 322, under the combined pressure of the cam 33 and the elastic force, drive the base plate 14 to reciprocate on the machine base 34. The speed of this reciprocating movement depends on the rotational speed of the motor 31. Through high-frequency, small-amplitude movements, i.e., vibration, the cardboard located between the two baffles 11 can be gradually moved towards the center, achieving the purpose of aligning the cardboard. Furthermore, the vibration causes almost no damage to the surface of the cardboard, making it suitable for use in cardboard boxes that require sealed folding, ensuring the accuracy and non-deformation of the folded edges of the cardboard box.

[0037] Furthermore, on the side away from the feed port 15, a rear guide plate 40 is detachably connected to the side wall of the base plate 14 by threaded fasteners. The rear guide plate 40 can form a thrust at the rear of the placement space by pre-determining the angle. If the baffle 11 aligns the cardboard from the left and right sides, the rear guide plate 40, together with the vibrating cardboard, can drive the cardboard to align from the rear of the cardboard, while the feed port 15 outputs the cardboard from the front of the cardboard.

[0038] It is known that the length of the baffle 11 may be slightly longer than the cardboard to allow the rear guide plate 40 to function.

[0039] Preferably, the entire device is tilted, with the side containing the feed port 15 slightly downward, which can be combined with gravity to smoothly output the cardboard.

[0040] Working principle of this utility model:

[0041] By adding a base plate 14 to the baffle 11 to form a blocking edge, the cardboard in the placement space is stably positioned in the placement space under the obstruction of the blocking edge. Then, the motor 31 is turned on to drive the baffles 11 on both sides to vibrate frequently, so that the staggered cardboard positions gradually become neat. The neat cardboard can be output from the feeding port 15 to the processing position of the die-cutting machine. The whole operation process can reduce the degree of manual intervention and reduce the lateral displacement between cardboards in the feeding device.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
