Description

[Technical field]

[0001] The utility model belongs to the technical field of packaging box packaging, in particular to a packaging box forming and feeding device. [Background technology]

[0002] For common products such as coffee capsules or chocolate, after the finished product is produced, a certain number of products of certain specifications need to be placed in a packaging box, and the packaging box needs to be folded one by one by flat box paper. The traditional method is manual box folding, which will lead to low packaging production efficiency, and is also prone to errors, and the packaging quality is also inconsistent. In order to adapt to automated production, there are corresponding automated devices designed to automatically fold boxes and complete the loading of packaging boxes. For example, a packaging box forming device disclosed in Chinese Patent Publication No. CN215283579U includes a box paper tray mechanism for storing flat box paper; a box paper suction cup mechanism, which is arranged above the box paper tray mechanism, and is used to suck up the box paper and transfer it to the upper forming conveyor belt; the upper forming conveyor belt is arranged on the rear side of the box paper tray mechanism, and the rear end is provided with a forming guide sleeve adapted to the bottom of the box paper; a forming pressing mechanism is arranged above the forming guide sleeve, and is used to press the box paper conveyed to the top of the forming guide sleeve and pass through the forming guide sleeve to fold the side panels of the bottom of the box. The upper and lower forming conveyor belts have their front ends arranged below the forming guide sleeves, and the conveyor belts are provided with forming bottom cavities matched with the forming guide sleeves at intervals, so as to sequentially receive the folded paper boxes passing through the forming guide sleeves; the above scheme can realize the automatic forming of the packaging boxes, but the provided box paper suction cup mechanism transports the flattened paper boxes to the upper forming conveyor belt through the translation mechanism, and the box paper suction cup mechanism occupies a large space, which will cause the entire packaging box forming device to occupy a large space, which is not conducive to the layout of the packaging production line, and this method can only transport box paper that is in a horizontal state and stacked up and down. If the box paper is in an upright state and placed left and right, the box paper cannot be transported.

[0003] Therefore, it is necessary to provide a packaging box forming and feeding device to solve the above technical problems. [Contents of the utility model]

[0066] The lateral guide plate 542 includes a front and rear lateral guide plate 5421 and a left and right lateral guide plate 5422. A passage gap 56 for the upper cover 205 of the box paper 200 to pass through is set between the front and rear lateral guide plate 5421 and the left and right lateral guide plate 5422. The lower pressure head 73 presses down to guide the box paper 200 into the guide cavity 55. The four tongue plates 204 are folded up before the first side plate 202. When the lower pressure head 73 continues to move downward, the four tongue plates 204 extend into the two first side plates 202 respectively.

Therefore, the positioning guide mechanism 5 is arranged on the straight edge of the magnetic suspension conveyor line 8, so that the power unit 82 drives the support clamping assembly 83 to drive the packaging box 300 to move forward in a straight line from the passage gap 56.

[0067] When a packaging box forming and loading device 100 of the present invention is applied, a stack of box papers 200 is placed on the feeding conveyor line 21 manually or by a robot, and the pushing plate 23 is pushed so that the box papers are located at the conveying end of the feeding conveyor line 21 and at the inner side of the frame 1, and are blocked by the baffle plate 22. When the first sensor 24 senses that there is box paper 200 on the baffle plate 222 of the baffle plate 22, the fourth driving member 41 of the suction and conveying mechanism 4 drives the rotating shaft 42 to rotate and drives the adsorption component 45 at the lower end of the swing arm bracket 43 to absorb the box paper 200, and the suction cup 452 adsorbs the box paper, and the fourth driving member 41 drives the rotating shaft 42 to rotate in the opposite direction, thereby driving the suction cup to pull out the box paper 200, and the feeding conveyor line 21 The box paper 200 continues to be transported forward and is blocked by the material blocking plate 22. At the same time, the connecting rod assembly 46 drives the lever member 47 to drive the adsorption assembly 45 to swing so that the box paper 200 changes from the upright state to the horizontal state and is placed on the carrying platform 31 of the pushing and conveying mechanism 3. The third driving member 331 of the pushing module 33 drives the pushing shaft 332 to rotate so that the roller 334 pushes the box paper 200 on the carrying platform 31 to the conveying module 32. The bottom of the box paper 200 is supported on the two second supporting plates 312. The roller 334 continues to roll on the box paper 200 to transport the box paper 200 to the left. At the same time, the two glue spraying heads 61 first spray the left ends of the two first side plates 202 respectively. Glue, as the conveying module 32 conveys the box paper 200, glue is sprayed on the right ends of the two first side plates 202 respectively. After the glue spraying is completed, the box paper 200 is pushed into the module 33 and the conveying module 32 and conveyed to the guide module 54. The guide plates 52 on the front and rear sides guide and correct the front and rear sides of the box paper 200, and the second side cover plate 207 at the leftmost end of the box paper 200 is restricted on the limiting plate 53. The four tongue plates 204 of the box paper 200 are correspondingly located on the four tongue plate guide supports 541. The fifth driving member 71 drives the support rod 72 to drive the lower pressure head 73 to move downward and guide the box paper 200 into the guide cavity 55. The four tongue plates 204 are located before the first side plate 20 2 is folded up, when the lower pressure head 73 continues to move downward, the four tongue plates 204 respectively extend into the two ends of the two first side plates 202 to achieve bonding and forming to obtain the packaging box 300, and the lower end of the packaging box 300 is supported on the supporting clamping assembly 83, and the height of the side plate of the packaging box 300 is lower than the height of the lateral guide plate 542. The upper cover 205 of the packaging box 300 is in a vertical state and is located in the passage gap 56. When the power unit 82 drives the supporting clamping assembly 83 to drive the packaging box 300 to move forward in a straight line, the upper cover 205 of the packaging box 300 passes through the passage gap 56, so that the packaging box 300 is transported to the next station by the power unit 82, and the molding and loading of a packaging box 300 are completed.
