Description

Technical Field

[0001] The invention relates to a packaging machine, in particular to a packaging box rotating feeding mechanism for turning over and pushing a plurality of packaging boxes, which is applied to a transparent film wrapping machine. Background Art

[0002] At present, the cartoning machine is a device that integrates materials (such as blister tablets), instructions (paper tablet instructions), paper boxes, etc. into small packaging boxes, and then integrates multiple small packaging boxes and repackages them into medium packaging boxes (i.e. box-in-box). It involves the repackaging of various types of items such as food, medicine, and cosmetics, and has a large market demand space. It needs to focus on the design of multiple processes such as waste rejection, touch flipping (from horizontal flipping to vertical placement), multiple small box transfer pushing, and stacking storage. Transparent film wrapping machine (transparent film strapping machine) is a packaging equipment that wraps multiple packaging boxes with transparent film. When pushing the packaging box forward, due to the long stroke of the pusher and the difficulty of lifting it up to make room for the subsequent packaging boxes to continue to follow up, it is necessary to stop the work of the box erecting mechanism in order to avoid damage caused by continuous friction of the packaging box in the box flipping belt. Due to the blocking of the packaging box, it is time-consuming and wear-prone, so the packaging speed of the equipment is limited. Summary of the invention

[0003] The object of the present invention is to overcome the above technical deficiencies and to provide a packaging box rotating feeding mechanism which is wear-free and can realize simultaneous flipping and pushing of multiple packaging boxes.

[0004] The object of the present invention is achieved through the following technical scheme: a packaging box rotary feeding mechanism comprises a platform frame and an archway, a feeding rack is mounted on the platform frame, a rotating spindle is mounted on the feeding rack, a plurality of clamping box assemblies are mounted on the rotating spindle, the clamping box assembly comprises a feeding clamping box seat, a bidirectional screw and a guide light rod are respectively mounted on the top of the feeding clamping box seat, a width adjustment hand wheel is mounted on the bidirectional screw, a moving seat is mounted on both sides of the bidirectional screw and the guide light rod, and a clamping plate is mounted on the lower part of the moving seat; the rotating spindle is connected to a rotary feeding power source through a rotating intermediate transmission assembly, and a main pushing mechanism is mounted on the platform frame and at the side of the feeding rack.

[0005] The rotating intermediate transmission component includes a main gear mounted on a rotating main shaft, the main gear is connected to a feeding driven wheel through a sub-gear and a sub-gear shaft, the feeding driven wheel is connected to a feeding driving wheel through a feeding synchronous belt, and the feeding driving wheel is connected to a rotating feeding power source.

[0006] The outer end of the bidirectional screw is provided with a screw locking block. The clamping box assembly has four groups, each of which has an angle of 90 degrees and forms four groups in a circle on the rotating main shaft.

[0007] After adopting the structure of the present invention, the horizontally placed packaging box that has completed the packaging of materials and instructions passes through the clamping box of the clamping box assembly, and the rotating main shaft drives the clamping box assembly and a row of packaging boxes to flip as a whole, so that a row of packaging boxes is turned from the original vertical state to the horizontal state, and finally pushed by the main pushing mechanism to fully prepare for the final packaging box film wrapping. Thus, a series of processes such as the clamping box flipping and pushing of the packaging box are completed in one time and fully automatically, effectively reducing the material blocking time and not causing wear. The overall packaging speed, packaging efficiency and packaging quality are significantly improved by improving the feeding method. It is particularly suitable for the packaging requirements of high-speed box loading and wrapping. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Reference Figures 1 to 3 It can be known that the present invention is applied to the packaging box rotary feeding mechanism of the transparent film wrapping machine, comprising a platform frame 1 (which is arranged horizontally) and a memorial arch 2 (which is arranged vertically), on which a feeding frame 50 (one on the left and one on the right, embedded in the corresponding position of the platform frame) is installed, on which a rotating main shaft 51 is installed (between), on which a plurality of clamping box assemblies 52 (a total of four groups, with an angle of 90 degrees between each group and forming four groups in a circle on the rotating main shaft) are installed, the clamping box assembly 52 comprises a feeding clamping box seat 53, on which the feeding clamping box is installed. A bidirectional screw 54 and a guide light rod 55 (both of which are arranged in parallel) are respectively mounted on the top of the seat 53, a width adjustment hand wheel 56 is mounted on the bidirectional screw 54, and a movable seat 57 is mounted on both sides of the bidirectional screw 54 and the guide light rod 55, and a clamping plate 58 (one on the left and one on the right) is mounted on the lower part of the movable seat 57; the rotating spindle 51 is connected to a rotating feeding power source 59 (a rotating feeding motor) through a rotating intermediate transmission component, and a main pushing mechanism 6 (located on the left side of the feeding rack 50) is mounted on the platform frame 1 and on the side of the feeding rack 50.

[0013] The rotating intermediate transmission assembly includes a main gear 60 mounted on the rotating main shaft 51, the main gear 60 is connected to a feeding driven wheel 63 through a sub-gear 61 (and a sub-gear shaft), the feeding driven wheel 63 is connected to a feeding driving wheel 62 through a feeding synchronous belt 64, and the feeding driving wheel 62 is connected to a rotating feeding power source 59. A screw locking block 65 is installed at the outer end of the bidirectional screw 54.

[0014] The longitudinal stacking type box collection, flipping, sorting and pushing device used in the present invention has a longitudinal stacking mechanism 8 (its stacking frame is embedded in the corresponding position of the platform frame) installed on the platform frame 1 and at the side of the archway 2, a material sorting and pushing mechanism 3 installed on the archway 2 and above the longitudinal stacking mechanism 8 of the box, and a rotating feeding mechanism 5 of the box installed on the platform frame 1 and at the side (subsequent process, right position) of the material sorting and pushing mechanism 3. A material storage platform 4 is installed on the platform frame 1 and between the longitudinal stacking mechanism 8 of the box and the rotating feeding mechanism 5 of the box. A feeding and conveying assembly 7 is installed on the platform frame 1 and at the joint with the longitudinal stacking mechanism 8 of the box.

[0015] Referring to the accompanying drawings, the working principle of the present invention is as follows: the transversely placed packaging boxes that have completed the packaging of materials and instructions are conveyed by the feed conveyor assembly 7 and enter the packaging box longitudinal stacking mechanism 8 to complete the longitudinal stacking of the packaging boxes in multiple rows and columns. Afterwards, the push rod of the material sorting and pushing mechanism 3 pushes the longitudinally stacked packaging boxes into the material storage platform 4. Then, it is pushed into the clamping box assembly 52 of the packaging box rotary feeding mechanism 5 and clamped by the clamping plate 58 (according to the specification requirements of the packaging box, the movable seat 57 on the bidirectional screw 54 is moved by rotating the width adjustment hand wheel 56 to tighten or loosen the clamping plate), and the rotary feeding power source 59 works to rotate the rotating main shaft 51 by rotating the intermediate transmission assembly, and rotates the clamping box assembly with the packaging box 90 degrees, so that a row of packaging boxes is flipped as a whole from a longitudinal vertical state to a group of packaging boxes in a horizontal state, and finally pushed by the main pushing mechanism 6 to the inside of the transparent film wrapping machine to finally complete the film coating and wrapping work of a group of packaging boxes (pushing one row in turn, rotating once, and pushing one group).

[0016] The present invention adopts a multi-column and multi-row lifting and stacking structure to sort the packaging boxes at the maximum possible speed, which is conducive to matching the output of the front-end cartoning machine. The number of boxes and packages is controlled by a program, and the stacking structure is adjustable and suitable for packaging boxes of different specifications. According to the specifications of the packaging boxes, the packaging boxes on the storage platform station are pushed into the packaging box rotating feeding mechanism one by one in a single row by a segmented small push method. The packaging box rotating feeding mechanism has four groups of clamping box components distributed in a circle. The length range of the clamping components is adjustable and suitable for packaging boxes of different specifications. Its rotation driving force adopts servo transmission and has precise positioning. The feeding channel of the transparent film wrapping machine is symmetrically distributed about the center. Therefore, when distributing the packaging boxes, the packaging box rotating feeding mechanism must ensure that the center of the packaging box after rotation is aligned with the center of the feed channel.
