Description

Cardboard adsorption device for carton packaging machine

technical field

The utility model relates to a carton packaging machine, in particular to a cardboard adsorption device. the

Background technique

Commonly seen carton packaging machines, as shown in Figure 1, the packaging machine 100 is mainly provided with an inlet conveyor belt 101, so that products such as square bottles or prototype bottles enter the inlet conveyor belt 101 from the upstream conveyor belt in a row or in a loose manner, and then With the bottle-separating conveyor belt mechanism 102 and the bottle-separating guide mechanism 103, the bottle products are separated at intervals in the bottle-separating area according to the number of bottles in the packaging box, and then the bottle products are pushed to the fixed plate by the bottle-separating push rod mechanism 104 105; At the same time, the cardboard is first manually installed in the cardboard storage area mechanism 106, after being pushed forward by the cardboard storage area mechanism 106, each cardboard is sucked out in sequence by a cardboard suction device 107, and then placed on the cardboard climbing On the assembly mechanism 108, the cardboard is transported by the cardboard climbing chain 109 to the bottom of the fixed plate 105, so that the cardboard and the product overlap at the entrance of the forming conveyor belt mechanism 110, and the cardboard and the product are sent into the carton packaging mechanism 111 together Carry out sealing. the

The cardboard adsorption device 107 of the above-mentioned carton packing machine, as shown in FIG. 2 , mainly utilizes two sets of eccentric runners 201 and 202 to synchronously drive a shaft 203 installed therebetween, and then several sets are respectively installed on both sides of the shaft 203. The suction cups 205 at the ends of several poles 204 absorb the cardboard, and then the cardboard stored in the cardboard storage area mechanism 106 is shifted to the cardboard climbing mechanism 108 . the

Therefore, the above-mentioned configuration of using two sets of eccentric runners 201, 202 to synchronously drive the shaft 203 to rotate is not only because the transmission mechanism for controlling the synchronous rotation of the eccentric runners needs to be more precise, but also because the two sets of eccentric runners rotate synchronously through the shaft. As a result, when the two sets of eccentric runners cannot maintain the same running speed due to the wear and aging of the components of one of the eccentric runners, the shaft will be deflected or the suction cup will not be able to fully rotate. The surface of the adsorbed cardboard will affect the efficiency of adsorbing the carton; moreover, because the whole mechanism is relatively complicated, the manufacturing cost is high, and the maintenance cost is also high, which affects the competitiveness of the market. the

Detailed ways

The cardboard adsorption device of the carton packaging machine of the present invention, the carton packaging machine has the same mechanism as the conventional carton packaging machine, the entrance conveyor belt, the bottle separating conveyor belt mechanism, the bottle separating guide mechanism, the bottle separating push rod mechanism, the fixed plate, the cardboard The storage area mechanism, the cardboard climbing group mechanism, the cardboard climbing chain, the forming conveyor belt mechanism, and the carton packaging mechanism are not described here because the above-mentioned composition is not the main point of this creation. the

The following is an explanation of the cardboard adsorption device featured in this creation only in conjunction with the drawings: 

As shown in Figures 3, 4, and 5, the cardboard adsorption device of the carton packaging machine of the present invention, the cardboard adsorption device 300, includes a frame 41, a servo transmission mechanism 42, a vacuum pump mechanism 44, an eccentric wheel mechanism 45, And a vacuum chuck assembly 46; wherein, the eccentric wheel mechanism 45 is driven by the servo transmission mechanism 42, the eccentric wheel mechanism 45 is provided with an eccentric wheel 46, and the eccentric wheel 46 is provided with a hollow one-sided cantilever support shaft 5 extending to one side A set of vacuum chuck assembly 46 is sleeved on the shaft arm of the single-side cantilever support shaft 5, and the vacuum chuck assembly 46 is composed of a plurality of oppositely arranged support rods 461, and a vacuum channel 462 is formed inside each support rod 461, A circular corrugated sucker 463 is arranged at its end, and the outside of each support rod 461 is connected to each other by a through pipe 464, and one end of one of the through pipe 464 is connected to the vacuum pump mechanism 44; The axle 5 can be rotated in situ by a runner 50 (as shown in FIG. 5 ). the

In addition, the inside of the vacuum channel 462 is provided with a vacuum discharge pipe 465, one end of the vacuum discharge pipe 465 is connected to the suction cup 463, and the other end is connected to the external pipe 464, whereby the vacuum pump mechanism 44 Control the vacuum channel 462 to be in a vacuum state, so that the suction cup 463 has the adsorption function; or, use the vacuum discharge tube 465 to introduce air to destroy the vacuum state of the vacuum channel 462, so that the suction cup 463 loses the adsorption function. the

During implementation, when the servo transmission mechanism 42 transmits power to the eccentric wheel 46 through the sprocket, and when the eccentric wheel 46 rotates according to the axis, it drives the hollow one-side cantilever support shaft 5, because the hollow one-side cantilever support shaft 5 is installed far away from the On the relative position of the axis of the eccentric wheel, the vacuum suction cup assembly 46 installed on the hollow single-side cantilever support shaft 5 has a non-perfect circular trajectory. the

Therefore, when the suction cup 463 moved to the farthest position from the center of rotation of the eccentric wheel along the motion track, the plane of the suction cup 463 was just in contact with the surface of the cardboard in parallel, and by the plane contact of a certain pressure and the vacuum state inside the suction cup 463, The cardboard is tightly adsorbed, and then, along with the continuous rotation of the eccentric wheel 46, the suction cup 463 that is adsorbed on the cardboard continues to move along the aforementioned track to a position closer to the center of rotation of the eccentric wheel, and it just coincides with the cardboard climbing group mechanism. At this time, the suction cup vacuum release device is connected to the atmosphere, because the atmospheric pressure begins to enter the vacuum channel, so that the vacuum in the suction cup is lost, so the cardboard is loosened and dropped to the conveyor belt, and sent to the carton packaging The organization carries out packaging and packaging. the

Since the suction cup assembly is fixed on both sides of the support rod, it is distributed symmetrically. When the eccentric wheel rotates once, the suction cardboard device completes a continuous action of sucking and placing cardboard, and the above-mentioned vacuum suction cup assembly 46 can be shown in the figure Set 4 pairs, or you can set more than one pair according to actual needs. the

Moreover, the cardboard adsorption device of the carton packaging machine of the present creation uses the hollow single-side cantilever support shaft 5 to drive the vacuum suction cup assembly 46 to move. The hollow single-side cantilever support shaft 5 is not only simple in structure and lightweight, The manufacturing cost is low, the maintenance is easy to implement, and the maintenance cost is relatively reduced. the

Based on the above, the cardboard adsorption device of the carton packaging machine of this creation has an unprecedented innovative structure. It has not been seen in any publications, and there is no similar product on the market. Therefore, its novelty should be No doubts. In addition, the unique features and functions of the present invention are far beyond the conventional ones, so it is indeed more progressive than the conventional ones, and it complies with the requirements of the Chinese Patent Law on the application requirements for new patents, and the patent application is filed according to law. the

The above is only a preferred embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications that can be easily conceived by those familiar with the art in the field of the present invention can be covered. In the following patent scope of this eucalyptus. the
