Description

Technical Field

[0001] The invention belongs to the technical field of carton processing, and in particular relates to a slotting device and method for carton production. Background Art

[0002] As a packaging material, cartons play an important role in the transportation, storage and sales of goods. With the rapid development of e-commerce and the growing logistics industry, the demand for cartons has continued to increase, which has promoted the technological progress and innovation of carton production equipment, especially slotting equipment. In the process of carton forming, slotting is a key step, which refers to cutting grooves on the cardboard for easy folding and bonding. These grooves determine the shape, strength and sealing of the carton. Carton slotting mostly uses slotting equipment, which not only has the function of slotting, but also has the functions of cutting and pressing out folding marks; However, existing carton slotting equipment often only has the ability to slot and creasing in straight lines. When the finished carton needs to have both straight and oblique slotting and creasing, the cardboard often needs to be slotted twice. Not only is the production efficiency of the carton low, but the secondary slotting often requires the cardboard to enter the equipment obliquely, which requires readjustment of the cardboard limit, which is not only inefficient but also easily causes the cardboard to deviate, resulting in the cardboard being scrapped.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0021] Please see attached Figures 1 to 7As shown, it is the first embodiment of the present invention, which provides a slotting device for carton production, including two side boxes 1, a loading platform 2 is fixed in the middle of one end of the two side boxes 1, and two cardboard conveying mechanisms 5 are installed between the two side boxes 1. The installation height of the cardboard conveying mechanism 5 is located on the upper surface of the loading platform 2; An adjustable tool holder 6 is installed on both sides of one of the cardboard conveying mechanisms 5. The adjustable tool holder 6 includes two rotating shafts 61. One end of the rotating shaft 61 is rotatably connected to a first lifting slider 63. The first lifting slider 63 is slidably installed inside one of the side boxes 1. The other end of the rotating shaft 61 is rotatably connected to a second lifting slider 64. The second lifting slider 64 is slidably installed inside the other side box 1. A first synchronous motor 62 is installed at one end of the second lifting slider 64 and located inside the other side box 1. The output end of the first synchronous motor 62 is connected to the other end of the rotating shaft 61. A straight slotting module 7 and an oblique slotting module 8 are respectively installed on the outer sides of the two adjustable tool holders 6. The oblique slotting module 8 includes a second upper half ring 81 and a second lower half ring 82. The second upper half ring 81 and the second lower half ring 82 are connected by screws. The second upper half ring 81 and the second lower half ring 82 are installed on the outer side of the rotating shaft 61, and the second upper half ring 81 and the second lower half ring 82 can slide on the outer side of the rotating shaft 61. A second locking hole is provided on the top of the second upper half ring 81. A second positioning screw is installed in the second locking hole. Rotating the first positioning screw can fix the second upper half ring 81 and the second lower half ring 82. A second tool mounting frame 83 is installed on the outer side of the second upper half ring 81 and the second lower half ring 82. A connecting plate 84 is fixed on the outer side of the second tool mounting frame 83. A diagonal tool 85 is installed on one side of the connecting plate 84. The shape of the diagonal tool 85 is spiral. A cardboard limiting mechanism 3 is installed above the feeding platform 2 and is used to position the cardboard; In the above, when the cardboard is slotted, the specifications of the cardboard limiting mechanism 3 are adjusted, and the cardboard is placed at the cardboard limiting mechanism 3, the device is started, and the cardboard is rolled into the adjustable tool holder 6 through the cardboard conveying mechanism 5, and the first synchronous motor 62 can drive the rotating shaft 61 to rotate, so that the straight line slotting module 7 and the oblique slotting module 8 rotate. When the straight line slotting module 7 rotates, the cardboard between the two straight line slotting modules 7 can be indented in a straight line. When the cardboard passes through the rotating oblique slotting module 8, since the shape of the oblique line tool 85 is set in a spiral shape, the contact position of the oblique line tool 85 and the cardboard will change when rotating to different angles, so that the surface of the cardboard can be obliquely folded and slotted. At the same time, as the length of the oblique line tool 85 increases, the oblique line that can be slotted or indented has a larger inclination angle. By replacing oblique line tools 85 of different specifications, the oblique line angle of the slot can be adjusted, so that oblique slotting and indentation at different angles can be applied, which is more practical.

[0022] Furthermore, a sliding loading push plate 21 is installed on the upper surface of the loading platform 2, and an electric slide is installed inside the loading platform 2. The bottom of one end of the loading push plate 21 is connected to the sliding end of the electric slide. When the cardboard is transported, the electric slide drives the loading push plate 21 to reciprocate, and the stacked and bottom cardboard is transported into the device.

[0023] In a preferred embodiment, please refer again to Figure 6 The linear slotting module 7 includes a first upper half ring 71 and a first lower half ring 72, which are connected by screws. The first upper half ring 71 and the first lower half ring 72 are installed on the outside of the rotating shaft 61, and the first upper half ring 71 and the first lower half ring 72 can slide on the outside of the rotating shaft 61. A first locking hole is provided on the top of the first upper half ring 71, and a first positioning screw is installed in the first locking hole. Rotating the first positioning screw can fix the first upper half ring 71 and the first lower half ring 72. A first tool mounting bracket 73 is installed on the outside of the first upper half ring 71 and the first lower half ring 72, and a linear tool 74 is provided on the outside of the first tool mounting bracket 73.

[0024] In this embodiment, the first upper half ring 71 and the second upper half ring 81 are respectively provided with a first positioning screw and a second positioning screw. Locking the first positioning screw and the second positioning screw can fix the position of the first upper half ring 71 and the second upper half ring 81. On the contrary, when the first positioning screw and the second positioning screw are loosened, the first upper half ring 71 and the second upper half ring 81 can slide on the rotating shaft 61, so that the position of the linear slotting module 7 and the oblique slotting module 8 can be adjusted. At the same time, the first tool mounting bracket 73 installed on the outer side of the first upper half ring 71 and the upper part of the first tool mounting bracket 73 outside the second upper half ring 81 are provided with adjustment holes. The positions of the adjustment holes correspond to the upper parts of the first locking hole and the second locking hole. After completing the installation of the linear tool 74 and the oblique tool 85, the positions of the linear slotting module 7 and the oblique slotting module 8 can still be adjusted, which is more convenient and practical.

[0025] Next, please refer to Figure 5 A bidirectional threaded rod 66 is threadedly connected between the two first lifting sliders 63 and the two second lifting sliders 64 , and a second synchronous motor 65 is installed at the top of the bidirectional threaded rod 66 and inside the side box body 1 .

[0026] In the above, when it is necessary to replace the linear tool 74 and the oblique tool 85 of different diameters, the bidirectional threaded rod 66 can be driven to rotate by the second synchronous motor 65. When the bidirectional threaded rod 66 rotates, the threads with different spiral directions at both ends can simultaneously drive the two first lifting slide blocks 63 and the two second lifting slide blocks 64 to move in opposite directions respectively, thereby changing the distance between the corresponding linear tool 74 and the oblique tool 85 after replacement, so that it can complete the functions of indentation and grooving.

[0027] Secondly, please refer to Figure 4 The cardboard conveying mechanism 5 includes two conveying rollers, the surfaces of which are made of rubber material, a transmission motor is installed at one end of one of the conveying rollers, and the two conveying rollers are connected by gear meshing.

[0028] In the above, one of the conveying rollers can be driven to rotate by the transmission motor. When one of the conveying rollers rotates, the other conveying roller can be driven to rotate in the opposite direction under the meshing transmission, thereby completing the conveying of the cardboard.

[0029] In a preferred embodiment, please refer again to Figure 2The cardboard limiting mechanism 3 includes a fixed frame 31 and a sliding frame 32. The fixed frame 31 is fixed between the two side boxes 1. The sliding frame 32 is installed on one side of the fixed frame 31. There are two sliding frames 32. A double-sided limiting baffle 36 is installed on one side of the two sliding frames 32. The cross-section of the double-sided limiting baffle 36 is L-shaped. A limiting baffle mechanism 4 is installed in the middle of the fixed frame 31 and between the two sliding frames 32.

[0030] In this embodiment, the limit baffle mechanism 4 is arranged at one end of the loading platform 2, and is used to limit the side of the cardboard close to the cardboard conveying mechanism 5. At the same time, the double-sided limit baffle 36 installed between the two sliding frames 32 is used to limit the remaining three sides, thereby forming a four-sided limit pattern, which can prevent the cardboard from tilting during the loading process and causing the slotting position to be incorrect.

[0031] Next, please refer to Figure 2 The sliding frame 32 is slidably connected to the fixed frame 31, and the shape of the sliding frame 32 is L-shaped. A limit adjustment groove 22 is provided at one end of the loading platform 2, and a guide slider 33 is fixed to the bottom of one end of the sliding frame 32. The guide slider 33 is located inside the limit adjustment groove 22 and is slidably connected to the limit adjustment groove 22, and a first locking knob 34 is installed on one side of the guide slider 33; a cross bar is installed at the bottom of the sliding frame 32, and the sliding frame 32 is slidably connected to the outer side of the cross bar with a first sliding sleeve 35, a double-sided limit baffle 36 is fixed on one side of the first sliding sleeve 35, and a second locking knob 37 is installed on the other side of the double-sided limit baffle 36.

[0032] As mentioned above, the sliding frame 32 can slide as a whole, thereby driving the double-sided limit baffle 36 to slide together. At the same time, the double-sided limit baffle 36 can also slide on the sliding frame 32, thereby being able to limit the position of three sides of the cardboard, thereby playing the role of limiting more cardboards. At the same time, a gap is provided between the bottom of the double-sided limit baffle 36 and the loading platform 2, and the gap can be used for the loading push plate 21 to pass through, so that the loading push plate 21 can load the limited cardboard.

[0033] Secondly, please refer to Figure 3 The limit baffle mechanism 4 includes a fixed limit plate 41 and a lifting limit plate 42. The lifting limit plate 42 is slidably connected to the bottom of the fixed limit plate 41. An adjusting knob 44 is installed on the top of the fixed limit plate 41. The adjusting knob 44 is rotatably connected to the fixed limit plate 41. An adjusting screw is fixed to the bottom of the adjusting knob 44, and the adjusting screw is connected to the internal thread of the lifting limit plate 42; the limit baffle mechanism 4 includes a second sliding sleeve 43, the second sliding sleeve 43 is slidably installed on the outside of the fixed frame 31, and one side of the second sliding sleeve 43 is fixed to the fixed limit plate 41. The fixed frame 31 is provided with two, and a locking knob is installed on one side of the second sliding sleeve 43.

[0034] In the above, when in use, according to the thickness of the cardboard used, the adjusting knob 44 is rotated to drive the adjusting screw connected at the bottom to rotate, and then the lifting and lowering limit plate 42 is controlled to be lifted and lowered under the drive of the thread, and the distance between the lifting and lowering limit plate 42 and the loading platform 2 is set to be equal to the thickness of the cardboard used, ensuring that only one cardboard can be conveyed into the slotting area each time, avoiding stacked paper from entering the slotting area, resulting in incomplete slotting.
