Description

Technical Field

[0001] The invention relates to the field of cardboard auxiliary correction for folding and forming equipment in corrugated paper box production machinery, in particular to a corrugated paper forming correction device, a correction method and a folding precision fine-tuning method. Background Art

[0002] Packaging cartons are made of paper products and are used to pack various items. Cartons are divided into paper boxes, color boxes, color boxes and oversized paper boxes. Cartons are low-cost, easy to pack, suitable for adding fillers, product factory packaging, item transportation, material sorting, etc.

[0003] Although packaging cartons are paper products, they are used for transportation and product protection, so there are strict requirements for their quality. The carton's compression resistance, edge pressure, bonding strength, puncture, simulated transportation shock resistance, and drop tests must meet the requirements.

[0004] In the production process of corrugated box production line, after the previous printing, slotting and gluing processes are completed, it is necessary to enter the folding and forming process. In the folding and forming process, the forming of the folding part is very critical. At present, the folding and forming is done by setting a row of pulleys. By setting the angle of this row of pulleys to a gradual angle, the cardboard is pushed to gradually bend and finally folded during the conveyor belt conveying process. Although the current forming device completes the folding of the cardboard, the forming is not ideal, and there will be at least the following problems:

[0005] 1. Folding is critical. Since the current folding forming mechanism only uses pulleys to assist in bending and folding, if the forming is not done well, not only will the finished carton be unsightly, but it will also cause the following problems: (1) The folded part of the cardboard will bulge and not be parallel to the cardboard surface. At the same time, when the carton is unfolded during use, the edges and corners of the carton will correspond to the bulged folded part. The edges and corners of the carton will be arc-shaped, which is not beautiful as a whole and has uneven edges and corners. It will also cause the carton to have poor stability, poor strength and reduced load-bearing capacity; (2) The cardboard is not folded neatly, with the upper and lower parts misaligned and the edges not aligned; and the two ends of the cardboard are not aligned, so that the width of the blades on both sides of the cardboard are inconsistent, and the inconsistency will cause the assembled carton to be crooked. If the above products appear in the industry, they are considered waste;

[0006] 2. If the grooves of the carton are slightly uneven in the previous slotting process, the folding position in the folding process cannot be accurately located at the center of the slots. This will cause the edges and corners of the carton to not be accurately located between different cover plates when the carton is used, and will also cause interference between the cover plates when the carton is sealed.

[0007] 3. In addition, for cartons of different sizes, the required slot sizes and positions are also different, so the corresponding bending positions are also different; and the current folding parts can only be adjusted when the equipment is stopped, and the adjustment process is very cumbersome, so when producing different specifications of cardboard, adjusting different cardboard folding widths consumes a lot of equipment and labor costs;

[0008] 4. In the production process of corrugated box production line, when the previous printing, slotting and gluing processes are completed and the cardboard is transferred to the folding and forming parts, the folding work begins. At this time, if the cardboard is in the position of the conveyor belt with a small angle deviation, the folded carton will also be uneven and the edges of the cardboard will not be aligned, resulting in a high defective rate in the current carton production process; and the current folding parts are to find that the cardboard is uneven, and then repeat the machine press to correct it after folding. Although this can also be corrected, it is not easy to adjust after folding, and repeated machine pressing will also cause the cardboard to have poor load-bearing capacity. Summary of the invention

[0066] Example 2

[0067] like Figures 1 to 7 As shown, the corrugated paper folding correction method of the present invention, this embodiment 2 includes the corrugated paper forming correction device described in embodiment 1, and the corrugated paper forming correction device is arranged at the front end of the corrugated paper folding and forming equipment;

[0068] The part of the paperboard to be folded is arranged between the forming wheel 13 and the folding wheel 16 of the corrugated paper forming and correction device for pre-pressing;

[0069] See also Figure 8 , using the folding wheel 16 to press out the folds of the paperboard inward; using the grooves of the forming wheel 13 to press out the edges and corners of the folded part of the paperboard and eliminate the bulge;

[0071] In view of the problem that a small amount of unevenness occurs in the grooves of the cardboard during the previous grooving process, a solution to this problem is to use the corrugated paper forming correction device described in Example 1, and start the first motor 5 and the first reducer 6 of the corrugated paper forming correction device when the cardboard to be folded passes between the forming wheel 13 and the folding wheel 16, so that the screw rod 34 drives the slider mounting plate 8 to move through the threaded connection with the nut 11, indirectly causing the forming wheel mounting plate 12 and the forming wheel 13 to move and push the cardboard forward, so that the grooving center of the cardboard is located at the center of the forming wheel 13 and the folding wheel 16, so as to correct the unevenness of the grooves of the cardboard.

[0073] See also Fig. 9 and Fig.10 ,in Fig. 9 It shows a three-dimensional diagram of the finished product after the cardboard is folded. Fig.10 Shown Fig. 9 A top view schematic diagram of Fig. 9 and Fig.10 The diagram shows a qualified product after folding. Fig. 9 and Fig.10 The cardboard on display is a complete carton when it is unfolded. Fig. 9 and Fig.10 For example, unqualified products are Fig. 9 There will be a bulge in the "C" area, which is the bulge formed by the folded cardboard mentioned in the previous text of this manual, and this bulge will cause Fig. 9 The edges of the "D" area are not aligned with the upper and lower layers, which will also cause Fig.10 The spacing between the "E" areas on the upper and lower sides is also inconsistent ( Fig.10 The middle part of the "E" area on the upper and lower sides is the pasting place of the cardboard 33); the above is the current situation of defective products. The present invention sets the part of the cardboard to be folded between the forming wheel 13 and the folding wheel 16 of the corrugated paper forming and correction device for pre-pressing, and uses the folding wheel 16 to press out the crease of the cardboard 33 folding inward; uses the groove of the forming wheel 13 to press out the edges and corners of the folding part of the cardboard 33 and eliminate bulges; uses the cooperation of the forming wheel 13 and the folding wheel 16 to achieve the pre-pressing of the cardboard 33, so that the folding part of the cardboard 33 eliminates bulges and keeps it neat, so that the finished cardboard has high strength and strong load-bearing capacity; and solves the problems of upper and lower misalignment, edge misalignment, and inconsistent blade widths on both sides of the cardboard pasting place caused by bulges.

[0074] In order to solve the problem that the grooves of the paperboard 33 are slightly uneven during the groove opening process, the corrugated paper forming correction device is respectively arranged on both sides of the existing corrugated paper folding and forming equipment to Fig.10 For example, when there are corrugated paper folding and forming devices on both sides of the paperboard 33, the two sides of the paperboard 33 are respectively in contact with the forming wheels 13 of the corrugated paper forming and correction device, that is, in Fig.10 The left and right sides of the corrugated paper forming correction device are provided; by starting the first motor 5 and the first reducer 6, the screw rod drives the slider mounting plate 8 to move through the threaded connection with the nut 11, and indirectly causes the forming wheel mounting plate 12 and the forming wheel 13 to move. Fig.10 The left and right sides of the middle paperboard 33 are contracted inward or expanded outward by the forming wheel 13, so that the center of the slot of the paperboard 33 is exactly between the forming wheel 13 and the folding wheel 16, thereby realizing adaptive correction when there is a small amount of unevenness in the slot, so that the folding part of the paperboard 33 is exactly in the middle of the slot.

[0075] Example 3

[0076] like Figures 1 to 7 As shown, the method for fine-tuning the folding accuracy of corrugated paper of the present invention, this embodiment 3 includes the corrugated paper forming correction device described in embodiment 1 and the corrugated paper folding correction method described in embodiment 2, and the corrugated paper forming correction devices are respectively arranged on both sides of the existing corrugated paper folding and forming equipment, so that the forming wheels 13 in the corrugated paper forming correction devices on both sides of the corrugated paper folding and forming equipment are respectively abutted against the two sides of the paperboard;

[0077] The specific steps are:

[0078] Obtain the position of the cardboard on the folding and forming equipment and determine the angle of the cardboard;

[0079] The forming wheel 13 is driven to rotate by the second motor 26, the first pulley 28, the second pulley 30 and the synchronous belt of the corrugated paper forming correction device;

[0080] By controlling the acceleration and deceleration of the second motor 26, the forming wheels 13 on both sides of the corrugated paper folding and forming device maintain the same or different rotation speeds, so as to adjust the angle of the paperboard in the corrugated paper folding and forming device.

[0081] by Fig.10For example, the above steps are that when there are corrugated paper folding and forming devices on both sides of the cardboard 33, the forming wheel 13 abuts against the two sides of the cardboard 33, and by controlling the speed of the forming wheel 13 and using the friction between the forming wheel 13 and the cardboard 33, the forming wheel 13 drives the angle of the cardboard 33 to change, thereby achieving fine adjustment. This solves the problem that the current cardboard is slightly offset at the position of the conveyor belt, so that the folded carton is also uneven, the edges of the cardboard are not aligned, and defective products are caused.
