Description

Technical Field

[0001] This utility model relates to a material loading and bagging machine, and more particularly to a plastic fragment material loading and bagging machine. Background Technology

[0002] In the waste plastic recycling industry, the packaging of recycled plastic scraps typically involves placing bags at the bottom and allowing the scraps to fall freely into the bags from above. Due to gaps between the scraps, the weight of plastic scraps per unit volume of bag is insufficient, requiring more bags to complete the haphazard packing. To address this problem, this invention proposes an integrated squatting bag mechanism that achieves rapid and precise squatting bagging through mechanical linkage. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model proposes a plastic fragment loading and bagging machine.

[0004] The bag-squatting machine includes: a four-corner frame erected on the ground, and a bag-squatting mechanism installed in recessed holes in the ground; hooks for hanging packaging bags are installed at the four opposite corners of the four-corner frame. The bag-squatting mechanism includes: a bag-squatting platform supported at the bottom of the packaging bag, and a linkage drive mechanism located below the bag-squatting platform for driving the bag-squatting platform to move up and down rapidly. As plastic fragments fall from above into the bag opening, the bag-squatting platform located at the bottom of the packaging bag can move up and down rapidly at any time to eliminate gaps between plastic fragments inside the bag, ensuring that the packaging bag can be filled with more plastic fragments at once.

[0005] Furthermore, in order to be compatible with packaging bags of different specifications and lengths and to ensure that the shield bag platform can be adjusted in height, a lifting platform is provided below the linkage drive mechanism, and a lifting cylinder is provided below the lifting platform. The rod end of the lifting cylinder is connected to the lower part of the lifting platform, and the fixed end of the lifting cylinder is connected and fixed to the bottom of the countersunk hole.

[0006] Furthermore, the linkage drive mechanism includes: four sets of parallel double connecting rods, one end of which is hinged above the lifting platform and the other end of which is hinged below the squatting bag platform; two hinge shafts, each hinged to the middle of two sets of double connecting rods, drive the two hinge shafts to move horizontally closer or further apart from each other; wherein, the double connecting rods are two straight rods of the same length that are hinged to each other.

[0007] Furthermore, the rod end of the squatting bag cylinder is connected to a hinge shaft, and the fixed end of the squatting bag cylinder is connected to another hinge shaft.

[0008] Furthermore, in order to ensure that the included angle between the two straight rods on the double linkage is always greater than 90°, several protective rods are vertically installed on the lifting platform to limit the minimum distance between the squatting platform and the lifting platform.

[0009] Furthermore, in order to ensure that the stroke of the squatting cylinder can fully meet the maximum stroke of the squatting platform's vertical movement, the piston rod of the squatting cylinder cannot reach its maximum stroke when the squatting platform and the lifting platform reach their minimum distance.

[0010] The technical advantages of this invention are as follows: A vertically movable squatting platform is installed at the bottom of the packaging bag, ensuring that the platform's position is raised or lowered as plastic fragments fall into the bag, thus eliminating gaps between the fragments. This increases the packing capacity per unit volume from 800 kg to 1000 kg, an increase of approximately 20%. Furthermore, the use of a linkage drive mechanism, with the angle between the two straight rods on the double linkage always greater than 90°, amplifies the output force of the horizontally positioned squatting cylinder by at least 1.4 times in the vertical direction, achieving a fast and efficient squatting action for better packing results.

[0013] The following is combined Figure 1 The embodiments of this utility model will be described in detail below.

[0014] Figure 1 The diagram illustrates the specific structure of this utility model and the connection and positional relationship between its various components. The squatting bag machine includes: a four-corner frame 1 erected on the ground 100, and a squatting bag mechanism 2 installed in a recessed hole 102 under the ground 100. The four corners of the four-corner frame 1 are equipped with hooks 11 for hanging packaging bags 101. The squatting bag mechanism 2 includes: a squatting bag platform 21 supported on the bottom of the packaging bag 101, and a linkage drive mechanism 5 located below the squatting bag platform 21 for driving the squatting bag platform 21 to move up and down quickly.

[0015] Below the linkage drive mechanism 5 is a lifting platform 3, and below the lifting platform 3 is a lifting cylinder 4. The rod end of the lifting cylinder 4 is connected to the lower part of the lifting platform 3, and the fixed end of the lifting cylinder 4 is connected and fixed to the bottom of the countersunk hole 102. The linkage drive mechanism 5 includes: four sets of parallel double connecting rods 53, one end of which is hinged above the lifting platform 3 and the other end of which is hinged below the squatting bag platform 21; two hinge shafts 52 are respectively hinged to the middle of two sets of double connecting rods 53; and squatting bag cylinders 51 drive the two hinge shafts 52 to move horizontally closer or further away from each other. The double connecting rods 53 are two straight rods of the same length that are hinged to each other.

[0016] The rod end of the squatting cylinder 51 is connected to a hinge shaft 52, and the fixed end of the squatting cylinder 51 is connected to another hinge shaft 52. Several protective rods 7 are vertically installed on the lifting platform 3 to limit the minimum distance between the squatting platform 21 and the lifting platform 3, and to ensure that the included angle between the two straight rods on the double connecting rod 53 is greater than 90°. When the squatting platform 21 and the lifting platform 3 reach the minimum distance, the piston rod of the squatting cylinder 51 cannot reach the maximum stroke.

[0017] Working principle: Before the squatting operation, the packaging bag 100 is hung on the hooks 11 installed on the four-corner frame 100, allowing the recycled plastic fragments to continuously fall into the packaging bag 100. The lifting cylinder 4 adjusts the height of the squatting mechanism 2 according to the specifications and length of the packaging bag 100 by lifting the lifting platform 3, so that the squatting platform 21 just touches the bottom of the packaging bag 100. At this time, the rod end of the squatting cylinder 51 moves back and forth, pushing the two hinge shafts 52 to move closer or further apart, causing the included angle between the two straight rods on the double connecting rod 53 to change rapidly within the range of 90° to 180°, so as to drive the squatting platform 21 to continuously collide with the plastic fragments that have fallen into the packaging bag 100 from the bottom of the packaging bag 100, eliminating the gaps between the plastic fragments and ensuring that a single packaging bag can hold more plastic fragments.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
