[0002] In the process of packaging products, a carton opener is indispensable. The carton opener is also called a carton board opening device. The working process of the carton opener is to open the carton board first, then close the bottom cover and transmit it to the sealing work area to stick tape on the bottom of the carton.

[0003] With the development of carton design technology, its molding is becoming simpler and simpler. It only needs to open the plate-shaped carton board. Since the bottom of the box is composed of four pieces of paper that bite into each other in sequence, when the carton board is opened, the four pieces of paper bite into each other in sequence to form the bottom of the carton.

[0004] However, after the carton board is opened by the unpacking device in the prior art, the carton is easily deformed during the movement by the belts on both sides due to the lack of a fixing mechanism, which causes the sealing machine to be misaligned during the sealing operation; when the formed carton is loaded, the company needs to separately purchase a positioning mechanism to re-position the opened carton before the packing operation can be carried out, which increases the company's costs and makes the overall mechanism complicated and inconvenient to control; the unpacking action can only be performed on carton boards of the same specifications, but the packaging company cannot only package a single product, so it is necessary to add multiple production lines to meet production needs, which greatly increases the company's cost expenditure.

[0052] Furthermore, a universal wheel 102 is provided at each of the four corners of the bottom of the frame 1, and an adjustable support foot 103 is provided on the outer side of the universal wheel 102. When the position of the carton opener needs to be adjusted, the support height of the adjustable support frame 103 is adjusted so that the universal wheel 102 contacts the ground and the adjustable support foot 103 leaves the ground for easy movement; when the carton opener is moved into place, the support height of the adjustable support frame 103 is adjusted so that the adjustable support foot 103 contacts the ground and the universal wheel 102 leaves the ground and is fixed at a designated position without moving, thereby realizing the support function of the carton opener and convenient operation.

[0053] The specific implementation steps of the present invention are:

[0054] 1) According to the model of the carton, adjust and fix the connection positions of the second folding piece 413 and the third folding piece 414, and / or the first folding arm cylinder 401 and the first folding piece 412, and / or the second folding arm cylinder 402 and the first folding piece 402.

[0055] 2) Place the carton board on the inclined silo support 201, and keep the carton board in a vertical state through the push plate 203 on the rear side and the upper stopper 101 and the lower stopper 202 on the front side. The carton board moves forward under the automatic gravity and the push plate 203.

[0056] 3) The vacuum suction cup 304 in the box-taking mechanism 3 sucks a carton board by vacuuming, causing the carton board to deform slightly and then separate from the upper stopper 101 and the lower stopper 202. Then the slider 302 moves on the guide rail 301 with the vacuum suction cup 304 adsorbing the carton board, and transports the carton board to the forming mechanism 4.

[0057] 4) The first folding arm cylinder 401 extends to drive the positioning piece 411 to rotate 90°, so that the extension line of the first folding piece 412 forms an angle of 90° with the positioning piece 411. When the carton board is positioned at the angle, the second folding arm cylinder 402 extends to drive the second folding piece 413 to rotate 90°, so that the side of the carton board is bent 90° relative to the front or back of the carton board to open the carton board, and the positioning piece 411, the first folding piece 412, the second folding piece 413 and the third folding piece 414 embrace the four sides of the carton to position the carton, and the vacuum suction cup 304 releases the carton.

[0058] 5) The first closing cylinder 621 and the second closing cylinder 623 extend at the same time, driving the first rack 622 and the second rack 624 to move forward, so that the first gear 626 and the second gear 627 respectively meshing with the first rack 622 and the second rack 624 rotate at the same time, driving the connecting rod 625 to rotate and the second closing baffle 628 to rotate 90° to complete the closing of the left carton. At the same time, the third closing cylinder 612 extends to drive the first closing baffle 613 to rotate 90° to complete the closing of the right carton. Then the fourth closing cylinder 632 and the fifth closing cylinder 634 extend to respectively drive the first closing lever 633 and the second closing lever 635 to rotate 90° to complete the closing of the front and rear cartons.

[0059] 6) After the bottom cover is completely closed, the motor 503 drives the belt 501 to drive the forming mechanism 4 and the embraced carton to move forward along the conveying direction. After the carton enters the top of the sealing machine 701, the movement of the sealing machine 701 starts to work and seals the bottom cover of the formed carton. After the belt 501 drives the carton through the sealing machine 701, the sealing work is completed and the tape cutter cuts the tape. During the whole sealing process, the sealing baffle 702 on the top limits the upward displacement distance of the carton to ensure that the sealing is completed.

[0060] 7) After the subsequent step (empty box loading) is completed, the forming mechanism 4 opens to put down the carton, and the motor 503 drives the belt 501 to drive the forming mechanism 4 back to the initial position.

[0061] Obviously, the embodiments of the box opener of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
