[0022] The embodiment of the present application provides a buffer mechanism for packaging, and its main technical solution is that by arranging an insert plate 3 at the inner upper end position of the shaping box 1, two groups of insert plates 3 can realize small-scale stacking and shaping of product materials, and then cooperate with the buffer mechanism below to quantitatively bag or pack the product materials. The whole process is mechanized, and compared with traditional manual bagging technology, it has the advantages of high efficiency and reduced labor costs.

[0023] Example 1: Reference Figure 1 - Figure 3 As shown, a packaging buffer mechanism of this embodiment includes a shaping box 1, and a lower hopper 2 is provided at the top opening of the shaping box 1. The lower hopper 2 is used to guide product materials so that the product materials fall into the shaping box 1.

[0024] A stacking mechanism is provided at the inner upper end of the shaping box 1, including two groups of plug plates 3, which are horizontally symmetrically arranged. A cylinder 4 is provided on the back of the plug plate 3, wherein the plug plate 3 is driven by the cylinder 4 to slide horizontally. The main operation process is to push the plug plate 3 through the cylinder 4 so that the plug plate 3 is inserted into the inner cavity of the shaping box 1 to receive the product materials falling from above, thereby realizing a small amount of stacking and shaping of the product materials; on the contrary, the plug plate 3 is driven to retract by the cylinder 4, and the supporting force of the plug plate 3 is lost, and the product materials will fall downward.

[0025] In addition, support bearings 9 are provided on both ends of the shaping box 1. The support bearings 9 are located at the bottom of the plug board 3 and are in contact with the bottom end surface of the plug board 3. The support bearings 9 support the sliding of the plug board 3.

[0026] In some examples, guide shafts 5 are fixedly installed on the upper sides of both ends of the shaping box 1, a fixed plate 8 is provided at the end of the guide shaft 5, the cylinder 4 is fixedly installed in the middle of the fixed plate 8, a movable plate 7 is provided on the upper side of the head end of the plug plate 3, the movable plate 7 is fixedly connected to the output end of the cylinder 4, and sliding blocks 6 are provided in the middle of both ends of the movable plate 7, and the sliding blocks 6 are slidably installed on the outer surface of the guide shaft 5.

[0027] Among them, the guide shaft 5 and the fixed plate 8 form a stable support frame, thereby improving the stability of the installation of the cylinder 4 and the plug plate 3. At the same time, the sliding block 6 is slidably connected to the guide shaft 5, which guides the sliding of the movable plate 7, thereby improving the stability of the plug plate 3 when sliding in the horizontal direction.

[0028] Example 2: Reference Figure 1 - Figure 3 As shown, based on Example 1, a template also includes the following structure:

[0029] A buffer mechanism is provided in the middle of the inner side of the shaping box 1, and the buffer mechanism includes a flip claw 13. There are two groups of flip claws 13, which are horizontally symmetrically arranged. The flip claws 13 are driven to move by a driving assembly; the driving assembly includes two groups of chains 11, which are symmetrically arranged at the outer end of the shaping box 1 and are driven by a servo motor 12 to rotate synchronously.

[0030] Among them, the servo motor 12 is driven to drive the chain 11 to rotate, so that the flip claw 13 is inserted into the inner cavity of the shaping box 1, so as to receive the product materials dropped from the stacking mechanism. As the upper end continues to discharge materials, the flip claw 13 will gradually descend driven by the chain 11. When the set packaging volume is reached, the flip claw 13 also reaches the lower end position to flip and discharge materials, so as to put a certain amount of product materials into the packaging bag or packaging box located below for bagging.

[0031] A plurality of groups of long strip through holes 10 are arranged in the middle of both ends of the shaping box 1. The plurality of groups of long strip through holes 10 are evenly distributed. The driving assembly drives the flip claws 13 to slide vertically in the long strip through holes 10.

[0032] In some examples, the flip claws 13 are fixedly installed on the outer end surface of the chain 11, and at least two groups of flip claws 13 are installed on the outer end surface of the chain 11. During use, when the flip claws 13 of the lower layer rotate to the bottom position for flipping, the flip claws 13 of the upper layer just pass through the long strip through holes 10 into the inner cavity of the shaping box 1 to receive the material. The two groups of flip claws 13 are used alternately in a cycle, so that the packing process has continuity, effectively improving the efficiency of packing or bagging.

[0033] In addition, the number of the flip claws 13 can be installed as needed to maintain continuity during use and avoid the need to wait when caching product materials due to a small number of flip claws 13.

[0034] The working principle of the utility model is:

[0035] During use, the lower hopper 2 is first used to guide the products produced at the front end into the shaping box 1. At this time, the stacking mechanism arranged at the upper end of the inner side of the shaping box 1 will stack the products in small quantities. The specific operation process is that the cylinder 4 is driven to push the plug plate 3, so that the plug plate 3 is inserted into the inner cavity of the shaping box 1, and the products are received and then stacked.

[0036] Then, the cylinder 4 drives the insert plate 3 to retract. Without the resistance of the insert plate 3, the stacked products will fall downward. At this time, the two sets of flip claws 13 located below will catch the fallen products. As the upper end continues to discharge materials, the flip claws 13 will gradually descend. When the set packaging volume is reached, the flip claws 13 also reach the lower end position for flipping. At this time, the material loses its supporting force and will fall freely into the packaging bag or packaging box, thereby completing a metering cycle.

[0037] The flip claw 13 will rotate to the upper position under the rotation of the chain 11, and then pass through the long strip through hole 10 into the inner cavity of the shaping box 1 to continue the material receiving work;

[0038] In this process, the chain 11 and the rhythm speed of loading and unloading can be adjusted with the assistance of photoelectric and frequency converter.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
