Description

Technical Field

[0001] The invention relates to the technical field of packaging box hot stamping, in particular to an automatic feeding assembly used in the packaging box hot stamping process. Background Art

[0002] Hot stamping equipment is a kind of hot stamping printing equipment, which is mainly used to create a bright hot stamping effect on the surface of objects. It is often used in packaging, paper printing, clothing accessories and other industries to make printed products beautiful, colorful, durable and widely applicable. Therefore, the demand for hot stamping equipment is increasing;

[0003] Before hot stamping, packaging boxes are usually processed by cutting and other processes, and some debris and dust are likely to remain on the surface. If they are directly hot stamped, the area with debris cannot contact the hot stamping plate, which may easily lead to the loss of hot stamping patterns.

[0004] In addition, during the hot stamping process of packaging boxes, the most common problem is that the positioning and flatness of the packaging boxes are poor. It is also necessary to solve the problem that the packaging boxes are offset during the transmission of the packaging box cardboard, resulting in deviations in the hot stamping position. Moreover, since the packaging box is mostly composed of multiple groups of cardboards, even after folding, the gaps between the corresponding cardboards of the same packaging box will still be different, which can easily cause the hot stamping surface of the packaging box to tilt, which also causes the hot stamping position to shift and affect the hot stamping effect.

During the rotation of the toothed conveyor belt 3, the toothed guide roller 82 drives the rotating disk 84 to rotate along with the toothed conveyor belt 3, and an annular groove 85 is provided on the outer surface of the rotating disk 84 away from the rotating shaft. The annular groove 85 is elliptical, and the inner surface of the annular groove 85 is rotatably connected to a rotating column 88;

[0035] During the rotation of the rotating disk 84, the rotating column 88 is pushed and pulled reciprocatingly up and down as the contact position with the annular groove 85 changes. One end of the rotating column 88 penetrates into the outside of the annular groove 85 and is rotatably connected to the movable frame 86, and one end of the movable frame 86 spans the corresponding support plate 81 and is fixedly connected to the smoothing plate 83. The top end of the inner surface of the movable frame 86 is fixedly connected to a guide column 87, and the guide column 87 penetrates into the interior of the support plate 81 and is movably connected thereto. The rotating column 88 drives the movable frame 86 to move up and down along the annular groove 85, and the smoothing plate 83 presses the passing packaging box cardboard to make the packaging box cardboard flat.

[0036] Embodiment 3: Figure 2-7 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that an anti-deviating mechanism 9 is provided on the upper outer surface of the feeding table 1 between the two groups of support frames 4, and the pressed packaging box cardboard continues to be conveyed in the direction of the anti-deviating mechanism 9;

[0037] The anti-deviation mechanism 9 includes two groups of fixed plates 91 fixedly connected to the outer surface of the upper end of the toothed conveyor belt 3, the two groups of fixed plates 91 are respectively located on both sides of the toothed conveyor belt 3, and a movable bar 92 is movably connected to the outer surface of one side of the fixed plate 91 near the bottom end, one end of the movable bar 92 passes through the fixed plate 91 and is hinged to a driving bar 93, and the end of the driving bar 93 away from the movable bar 92 is hinged to a connecting bar 94, and a rotating column 2 95 is rotatably connected to the outer surface of the connecting bar 94 at a position corresponding to the annular groove 85, and the rotating column 2 95 passes through the inside of the annular groove 85 and is movably connected thereto, and the rotating column 2 95 reciprocates and pushes and pulls the connecting bar 94 under the drive of the annular groove 85, and the driving bar 93 pushes and pulls the movable bar 92 along with the connecting bar 94.

[0038] A guide rod 96 is movably connected to the outer surface of the fixed plate 91 at a position above the movable bar 92, and a connecting rod is fixedly connected between the guide rod 96 and the movable bar 92. One end of the guide rod 96 passes through one side of the fixed plate 91 and is fixedly connected to a connecting plate 910, and a correction plate 97 is provided on one side of the connecting plate 910.

[0039] The guide rod 96 pushes and pulls the correction plate 97 repeatedly along the surface of the toothed conveyor belt 3 along with the movable bar 92. A plurality of groups of limit columns 99 are arranged between the correction plate 97 and the connecting plate 910. One end of the limit column 99 is fixedly connected to the correction plate 97, and the other end passes through the outside of the connecting plate 910 and is movably connected thereto. A spring 98 is arranged on the outer surface of the limit column 99 between the correction plate 97 and the connecting plate 910, and the two ends of the spring 98 are respectively fixedly connected to the correction plate 97 and the connecting plate 910. Under the action of the spring 98, the correction plate 97 elastically corrects the position of the packaging box cardboard of different specifications.

[0040] The working process and principle of the present invention are as follows:

[0041] Step 1: Place the folded packaging box cardboard on the surface of the toothed conveyor belt 3 from the end close to the rubber roller 76, with the gold-stamped surface of the packaging box cardboard facing upward, and drive the conveyor roller 2 to rotate clockwise by the driving motor, so that the toothed conveyor belt 3 conveys the packaging box cardboard;

[0042] Step 2: When the packaging box paperboard is conveyed to the bottom of the rubber roller 76, the rubber roller 76 is attached to the packaging box paperboard under the action of the spring 1 74, and the packaging box paperboard continues to move along with the toothed conveyor belt 3. The motor 1 78 drives the reeling roller 75 to reel the adhesive tape 77 attached to the packaging box paperboard. The rubber roller 76 rotates under the traction of the adhesive tape 77, and the adhesive surface of the adhesive tape 77 adheres to the dust and debris on the surface of the packaging box paperboard.

[0043] Step 3: The cleaned packaging box cardboard is conveyed to the smoothing plate 83. During the rotation of the toothed conveyor belt 3, the toothed guide roller 82 drives the rotating disk 84 to rotate along with the toothed conveyor belt 3. Since the annular groove 85 is elliptical, during the rotation of the rotating disk 84, the rotating column 88 drives the movable frame 86 to move up and down along with the annular groove 85. The smoothing plate 83 presses the passing packaging box cardboard to make the packaging box cardboard flat.

[0044] Step 4: The pressed packaging box cardboard continues to be conveyed toward the hot stamping plate 6. When the packaging box cardboard passes through the two sets of correction plates 97, the second rotating column 95 pushes and pulls the connecting strip 94 reciprocatingly under the drive of the annular groove 85, and the driving strip 93 pushes and pulls the movable strip 92 along with the connecting strip 94. Therefore, the guide rod 96 pushes and pulls the correction plate 97 along the surface of the toothed conveyor belt 3 repeatedly with the movable strip 92. The correction plate 97 elastically corrects the position of packaging box cardboards of different specifications under the action of the second spring 98;

[0045] Step 5: After cleaning, laminating and correcting, the packaging box cardboard enters under the hot stamping plate 6, and the electric push rod pushes the hot stamping plate 6 downward to perform hot stamping on the packaging box cardboard.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
