Description

Technical Field

[0001] This utility model relates to the field of buffer structures, and in particular to a buffer structure for the bag-taking linkage of a bag-making machine. Background Technology

[0002] Currently, the automatic cement bagging machine uses a linkage mechanism to drive a suction cup to extract the cement bags. This bag-collecting linkage mechanism generates inertia during operation; excessive inertia can affect the bag-collecting process. Furthermore, the thickness of a stack of cement bags gradually decreases during bag collection, necessitating compensation for the stroke of the bag-collecting linkage mechanism.

[0003] In existing technologies, such as the "Automatic Bag-Taking Machine Bag-Taking Linkage Buffer Device" with Chinese authorization announcement number CN207712393U, a swinging part and a buffering mechanism are included. One end of the swinging part is hinged to the first end of the buffering mechanism, and the second end of the buffering mechanism is hinged to the bag-taking mechanism via a swing rod. The swinging part is used to drive the bag-taking mechanism to move sequentially through the buffering mechanism and the swing rod, and the buffering mechanism is used to reduce the motion inertia of the bag-taking mechanism. In this invention, when the bag-taking mechanism moves to its upper or lower limit position, it will generate a certain inertia because it will then move in the opposite direction. This inertia can be reduced by the buffering mechanism. Furthermore, the buffering force of the buffering mechanism can be adjusted by a regulating valve connected to the buffering mechanism, i.e., adjusting the pressure of the air source of the cylinder, so that the cylinder's stroke release compensates for the increased bag-taking stroke.

[0004] In existing technologies for automatic cement bag removal, the thickness of the cement bag stack gradually decreases as the cement bags are automatically removed, requiring operators to frequently adjust the air intake valve to control the cylinder's extension and retraction length. This reduces the ease of use of the automatic bagging machine.

[0005] Therefore, it is necessary to provide a buffer structure for the bag-collecting linkage of the bag-packing machine to solve the above-mentioned technical problems. Summary of the Invention

[0006] This utility model provides a buffer structure for the bag-collecting linkage of a bag-packing machine, which solves the problem that the thickness of the cement bag stack gradually decreases as the cement bags are automatically collected, thus requiring operators to frequently adjust the air intake valve to control the cylinder extension and retraction length, which reduces the ease of use of the automatic bag-packing machine.

[0007] To solve the above-mentioned technical problems, the present invention provides a bag-collecting linkage buffer structure for a bag-making machine, including a movable base and a storage box.

[0015] Compared with related technologies, the bag-collecting linkage buffer structure of the bag-collecting machine provided by this utility model has the following beneficial effects:

[0016] This utility model provides a bag-retrieving linkage buffer structure for a bag-packing machine. By setting a spring, when sealing cement bags, several sealed bags are stacked and squeezed into the inside of the storage box. At this time, the sealing cover is fixedly fitted onto the top of the storage box, so that the sealing cover can press and fix the cement bag inside the storage box.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a schematic diagram of a preferred embodiment of the bag-taking linkage buffer structure of the bag-taking machine provided by this utility model; Figure 2 is a front view of the bag-taking linkage buffer structure of the bag-taking machine shown in Figure 1; Figure 3 is a cross-sectional view of the storage box in the bag-taking linkage buffer structure of the bag-taking machine shown in Figure 1; and Figure 4 is a front view of the lifting plate in the bag-taking linkage buffer structure of the bag-taking machine shown in Figure 1. The bag-collecting linkage buffer structure of the bag-collecting machine includes a movable base 1 and a storage box 2. A cylinder 3 is movably connected inside the movable base 1. A rotating arm 4 is movably connected to the bottom of the cylinder 3. A swing arm 5 is movably connected to one end of the rotating arm 4. An adsorption seat 6 is installed at the bottom of the swing arm 5. A silencer 7 is fixedly installed on the bottom side of the cylinder 3. A spring 8 is fixedly connected to the bottom of the inner cavity of the storage box 2. A lifting plate 9 is movably connected inside the storage box 2. A closing cover 10 is movably connected to the top of the storage box 2. A lifting port 11 is opened on the top of the closing cover 10. A limit mechanism 12 is provided on the side of the inner wall of the storage box 2. A sliding ball 13 is movably connected to the side of the lifting plate 9. An adjustment mechanism 14 is provided inside the swing arm 5. A fixing mechanism 15 is provided on the side of the storage box 2.

[0025] The lifting plate 9 is located directly below the lifting port 11, and the lifting plate 9 and the spring 8 are perpendicular to each other. By setting the spring 8, when cement bags are being sealed, several sealed bags are stacked and squeezed into the inside of the storage box 2. At this time, the sealing cover 10 is fixedly fitted onto the top of the storage box 2, so that the sealing cover 10 can press and fix the cement bags inside the storage box 2. This allows the suction seat 6 to lift the cement bags out of the storage box 2 through the lifting port 11. At this time, the spring 8 can push the cement bags to continuously squeeze at the bottom of the lifting port 11, thereby achieving the effect of automatic lifting and adjustment of cement bags, thus bringing convenience to the bag removal of the bagging machine.

[0026] The first cylinder 3 and the storage box 2 are perpendicular to each other. By setting the first cylinder 3, when the cement bag is being taken out, the first cylinder 3 can dampen and limit one end of the rotating arm 4, so as to avoid the problem of continuous oscillation when the rotating arm 4 drives the swing arm 5 to swing, thereby improving the stability of the rotating arm 4 when it flips and swings, and thus achieving the buffering effect when the bagging machine is working.

[0027] The muffler 7 is perpendicular to the cylinder 3 and is located below the movable base 1. By setting the muffler 7, when the cylinder 3 is rotated and squeezed by the rotating arm 4, the gas inside the cylinder 3 can be discharged to achieve a buffering effect, so that the muffler 7 can absorb the sound of the airflow discharge, thereby avoiding the problem of generating a lot of noise when the gas in the cylinder 3 is discharged.

[0028] The limiting mechanism 12 includes a limiting groove 121, which is formed on the side of the inner wall of the storage box 2. A limiting block 122 is fixedly connected to the side of the lifting plate 9. By setting the limiting mechanism 12, when the spring 8 drives the lifting plate 9 to move up and down, the limiting groove 121 can limit the lifting plate 9 to move up and down through the limiting block 122, thereby avoiding the problem of tilting and deflection when the lifting plate 9 moves up and down, and thus improving the stability of the lifting plate 9 when moving up and down.

[0029] There are several sliding balls 13, which are evenly distributed on the side of the lifting plate 9. By setting the sliding balls 13, when the lifting plate 9 moves up and down, the sliding balls 13 can limit the movement of the lifting plate 9, thereby avoiding the problem of friction between the lifting plate 9 and the inner wall of the storage box 2 when it moves up and down, thus improving the smoothness of the lifting plate 9 when it moves up and down, that is, improving the smoothness of the cement bag lifting.

[0030] The adjustment mechanism 14 includes a second cylinder 141, which is movably sleeved inside the swing arm 5. One end of the second cylinder 141 is movably sleeved with a drive block 142, and one end of the drive block 142 is fixedly sleeved with one end of the adsorption seat 6. By setting the adjustment mechanism 14, when the adsorption seat 6 finishes adsorbing the cement bag, the second cylinder 141 is activated, which causes the second cylinder 141 to drive the drive block 142 to flip, that is, to drive the adsorption seat 6 to flip, thereby achieving the effect of flipping and adjusting the angle of the cement bag, that is, achieving the effect of adjusting the position of the cement bag.

[0031] The fixing mechanism 15 includes a flip-up buckle 151, which is movably sleeved on the side of the storage box 2. A locking block 152 is fixedly connected to the side of the sealing cover 10. By setting the fixing mechanism 15, when the cement bag is finished being added, the sealing cover 10 is sleeved on the top of the storage box 2. At this time, the flip-up buckle 151 is rotated so that the flip-up buckle 151 is sleeved inside the locking block 152, thereby fixing the sealing cover 10 on the top of the storage box 2, thus achieving the sealing and fixing effect of the cement bag.

[0032] The working principle of the bag-taking connecting rod buffer structure of the bag-taking machine provided by this utility model is as follows:

[0033] Step 1: First, when sealing cement bags, several bags are stacked and pressed into the storage box 2. The sealing cap 10 is then fixedly fitted onto the top of the storage box 2, pressing the cement bags firmly inside. This allows the suction seat 6 to lift the cement bags from the storage box 2 through the lifting port 11. The spring 8 continuously presses the cement bags against the bottom of the lifting port 11, achieving automatic lifting and adjustment of the cement bags, thus facilitating bag removal by the bagging machine. When removing cement bags, the first cylinder 3 dampens and limits one end of the rotating arm 4, preventing continuous oscillation when the rotating arm 4 drives the swing arm 5. This improves the stability of the rotating arm 4 during its rotation and provides a buffering effect during the bagging machine's operation. When the first cylinder 3 is compressed by the rotating arm 4, the gas inside the first cylinder 3 is released to achieve a buffering effect, allowing the silencer 7 to... The sound of airflow exhaust can be absorbed, thus avoiding the problem of large noise generated when the gas is discharged from cylinder 3. When the spring 8 drives the lifting plate 9 to move up and down, the limiting groove 121 can limit the lifting plate 9 to move up and down through the limiting block 122, thus avoiding the problem of tilting and offset when the lifting plate 9 moves up and down, thereby improving the stability of the lifting plate 9 when moving up and down.

[0034] Step 2: When the lifting plate 9 moves up and down, the sliding ball 13 limits the movement of the lifting plate 9, thus avoiding friction between the lifting plate 9 and the inner wall of the storage box 2, thereby improving the smoothness of the lifting plate 9's movement and the smoothness of the cement bag's lifting. When the suction seat 6 finishes absorbing the cement bag, the second cylinder 141 is activated, causing the second cylinder 141 to drive the drive block 142 to flip, thus causing the suction seat 6 to flip, thereby achieving the effect of flipping and adjusting the angle of the cement bag, that is, achieving the effect of adjusting the position of the cement bag. When the cement bag is finished being added, the sealing cover 10 is fitted onto the top of the storage box 2. At this time, the flip buckle 151 is rotated, so that the flip buckle 151 is fitted into the inside of the buckle block 152, thereby fixing the sealing cover 10 to the top of the storage box 2, thus achieving the effect of sealing and fixing the cement bag.

[0035] Compared with related technologies, the bag-collecting linkage buffer structure of the bag-collecting machine provided by this utility model has the following beneficial effects:

[0036] By setting spring 8, when cement bags are being sealed, several sealed bags are stacked and squeezed into the inside of the storage box 2. At this time, the sealing cover 10 is fixedly fitted onto the top of the storage box 2, so that the sealing cover 10 can press and fix the cement bags inside the storage box 2. This allows the suction seat 6 to lift the cement bags out of the storage box 2 through the lifting port 11. At this time, spring 8 can push the cement bags to continuously squeeze at the bottom of the lifting port 11, thereby achieving the effect of automatic lifting and adjustment of cement bags, thus bringing convenience to the bag removal of the bagging machine.
