Description

Technical Field

[0001] This utility model relates to the field of ton bag packaging machine technology, and more specifically, to a lifting and adjusting mechanism for a ton bag packaging machine. Background Technology

[0002] The ton bag packaging machine is a piece of equipment used for bagging bulk potatoes. It is equipped with a glued lifting screen, a reversible cloth belt, and a hydraulic lifting platform. The lifting platform is controlled by an operating handle to ensure that the material is filled layer by layer during bagging, with almost no drop height and material impact. This avoids damage to the potato skin due to excessive drop, making it the best choice for large-scale potato production and storage enterprises to achieve mechanized potato storage.

[0003] However, some problems still exist in actual use. For example, the aforementioned ton bag packaging machine usually connects the bag opening through the feeding pipe to allow materials to be filled into the ton bag, and uses hooks to hook the handle of the ton bag to maintain its shape. However, when the lifting platform is moved closer to the ton bag rack to reduce the drop height of the potatoes, the bottom of the ton bag is close to the lifting platform and will also rise, causing the bottom wrinkles to accumulate on the top of the platform. As a result, when the potatoes are dropped, they will cover these wrinkles, increasing the difficulty of unfolding the ton bag. As the platform descends and the gravity of the accumulated materials causes the wrinkles of the ton bag to gradually unfold, this will increase the friction between the potato surface and the bag, resulting in damage to the potato surface. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lifting and adjusting mechanism for a ton bag packaging machine, so as to solve the problem that when potatoes are dropped, they will press on the folds of the ton bag, which increases the difficulty of unfolding the ton bag, and when the ton bag is gradually unfolded, it will increase the friction between the potato surface and the bag.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lifting and adjusting mechanism for a ton bag packaging machine, comprising...

[0006] The packaging machine body has a controller fixedly installed on one side of the front side, a lifting and feeding machine on one side of the back side, a discharging machine on the top, and lifting and adjusting components on both the left and right sides.

[0007] The lifting and adjusting assembly includes a ton bag hanger, the end of which is slidably installed on the inner surface of the packaging machine body, and a ton bag clamping assembly is fixedly installed at the bottom of the ton bag hanger.

[0008] The ton bag clamping assembly includes a frame, an electric push rod, and a clamping arm mechanism. The top of the frame is fixedly installed to the bottom surface of the ton bag hanger. The electric push rod is located inside the frame, and its top end is fixedly installed to the bottom surface of the top of the frame. A movable block is fixedly installed at the bottom end of the electric push rod. Two sets of clamping arm mechanisms are symmetrically arranged, and the ends of the two sets of clamping arm mechanisms are fixedly installed to the two side surfaces of the movable block.

[0009] The clamping arm mechanism includes a fixed block, a short connecting rod, a first long connecting rod, and a second long connecting rod. One end of the fixed block is fixedly connected to the surface of the movable block, and the other end is rotatably installed to the top of the short connecting rod. One end of the first long connecting rod is rotatably installed to the bottom of the short connecting rod, and the other end is rotatably installed with a vertical rod. The middle part of the first long connecting rod is rotatably installed to the middle of the bottom of the movable block. One end of the second long connecting rod is rotatably installed to the middle of the bottom of the movable block, and the other end is rotatably installed to the inner surface of the vertical rod. A clamping block is fixedly installed at the bottom of the vertical rod.

[0010] The lifting and adjusting assembly also includes a lifting platform, a hydraulic cylinder, a hanging frame lifting mechanism, and a spring telescopic hook. The top of the lifting platform is fixedly installed with the bottom of the hydraulic cylinder, the surface of the hydraulic cylinder is fixedly installed with the side of the packaging machine body, the surface of the middle part of the ton bag hanging frame is fixedly connected with the end of the hanging frame lifting mechanism, and the top of the spring telescopic hook is fixedly installed with the bottom surface of the ton bag hanging frame.

[0011] The hanging rack lifting mechanism includes a vertical plate, a motor, a roller, a pulley, and a wire rope. The bottom of the vertical plate is fixedly installed on the inner surface of the packaging machine body. The motor is located on the side of the vertical plate. The output end of the motor is fixedly installed with a roller. The outer surfaces of both ends of the roller are rotatably installed with the inner surface of the vertical plate. The side end of the pulley is fixedly installed with the surface of the packaging machine body. One end of the wire rope is fixedly installed with the surface of the roller, and the other end is fixedly installed with the top surface of the ton bag hanging rack. The surface of the wire rope is movably installed with the surface of the middle part of the pulley.

[0012] The top sides of the lifting feeder are fitted to the inner wall of the top of the packaging machine body. The lifting feeder is equipped with several lifting screens to support the potato material and transport it to the discharge machine at the top of the packaging machine body.

[0013] The controller is electrically connected to the hydraulic cylinder, the motor, and the electric push rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by setting up a ton bag clamping assembly, after the worker hooks the ton bag handle onto the four spring telescopic hooks at the bottom of the ton bag hanger, the excess bag body can be alternately folded near the handle. Then, the folded part is placed between two sets of clamping arm mechanisms, and the electric push rod is controlled to retract, causing the connected movable block to move upward, which in turn causes the connected fixed block to move upward. At the same time, the short connecting rod is pulled upward, causing the first long connecting rod to rotate around the axis of its engagement with the movable block. The second long connecting rod rotates synchronously in parallel, causing the vertical rods at their rotating ends to move downward and move towards the center of the movable block. This causes the clamping block connected at the bottom to clamp the folded part of the ton bag. During the potato unloading process, as the lifting platform moves downward, the bag gradually unfolds, thus solving the problem of the bottom folds of the ton bag accumulating on the top of the lifting platform, causing the potatoes to be pressed on top of these folds when unloading, increasing the difficulty of unfolding the ton bag.

[0016] In the above scheme, by setting up a lifting and adjusting component, when hanging bags, the operator controls the motor to rotate, which drives the roller connected to the output end to rotate, causing the steel wire rope connected to its surface to loosen. The ton bag hanger connected to the other end of the steel wire rope moves downward along the slide groove on the surface of the packaging machine, thus facilitating the operator's bag hanging operation. After the bag is hung, the operator controls the ton bag hanger to rise to a high position, and at the same time controls the lifting platform and the ton bag hanger to move up to a suitable height. During the subsequent potato feeding process, the operator controls the hydraulic cylinder to gradually extend, driving the lifting platform and the ton bags and materials supported on it to gradually move down, thereby ensuring that the material is filled layer by layer during bagging, reducing the drop height and impact of the falling potatoes, and improving the quality of the material.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a lifting and adjusting mechanism for a ton bag packaging machine, including...

[0025] The packaging machine body 1 has a controller 2 fixedly installed on one side of the front of the packaging machine body 1, a lifting and feeding machine 3 is provided on one side of the back of the packaging machine body 1, a discharging machine 4 is provided on the top of the packaging machine body 1, and lifting and adjusting components 5 are provided on both the left and right sides of the packaging machine body 1.

[0026] The lifting and adjusting assembly 5 includes a ton bag hanger 52, the end of which is slidably installed on the inner surface of the packaging machine body 1, and a ton bag clamping assembly 6 is fixedly installed at the bottom of the ton bag hanger 52.

[0027] The ton bag clamping assembly 6 includes a frame body 60, an electric push rod 61, and a clamping arm mechanism 63. The top of the frame body 60 is fixedly installed on the bottom surface of the ton bag hanger 52. The electric push rod 61 is located inside the frame body 60, and the top of the electric push rod 61 is fixedly installed on the bottom surface of the top of the frame body 60. A movable block 62 is fixedly installed at the bottom end of the electric push rod 61. Two sets of clamping arm mechanisms 63 are symmetrically arranged, and the ends of the two sets of clamping arm mechanisms 63 are fixedly installed on the two side surfaces of the movable block 62.

[0028] The clamping arm mechanism 63 includes a fixed block 630, a short connecting rod 631, a first long connecting rod 632, and a second long connecting rod 633. One end of the fixed block 630 is fixedly connected to the surface of the movable block 62, and the other end is rotatably installed to the top of the short connecting rod 631. One end of the first long connecting rod 632 is rotatably installed to the bottom of the short connecting rod 631, and the other end is rotatably installed with a vertical rod 634. The middle part of the first long connecting rod 632 is rotatably installed to the middle part of the bottom of the movable block 62. One end of the second long connecting rod 633 is rotatably installed to the middle part of the bottom of the movable block 62, and the other end is rotatably installed to the inner surface of the vertical rod 634. A clamping block 635 is fixedly installed at the bottom of the vertical rod 634.

[0029] By setting up the clamping arm mechanism 63, after the two sets of clamping arm mechanisms 63 are brought together by the retraction of the electric push rod 61, the opposing clamping blocks 635 at their bottom ends are not completely attached. Instead, they are suspended a certain distance away from the outside of the bag body below the folded part of the ton bag, so as not to affect the unfolding of the bag body.

[0030] The lifting adjustment assembly 5 also includes a lifting platform 50, a hydraulic cylinder 51, a hanging frame lifting mechanism 53, and a spring telescopic hook 54. The top of the lifting platform 50 is fixedly installed with the bottom end of the hydraulic cylinder 51, the surface of the hydraulic cylinder 51 is fixedly installed with the side of the packaging machine body 1, the surface of the middle part of the ton bag hanging frame 52 is fixedly connected with the end of the hanging frame lifting mechanism 53, and the top of the spring telescopic hook 54 is fixedly installed with the bottom surface of the ton bag hanging frame 52.

[0031] By setting a spring telescopic hook 54, which is an existing spring telescopic lock structure, consisting of two interlocking semicircular rings and a spring set in the inner cavity of the larger semicircular ring, when hanging the ton bag, the worker presses the smaller semicircular ring into the inner part of the smaller semicircular ring and then puts the handle into the middle. Then, under the action of the spring, the smaller semicircular ring protrudes out of the outer part of the smaller semicircular ring, thereby fixing the handle of the ton bag and preventing it from falling.

[0032] The hanging frame lifting mechanism 53 includes a vertical plate 530, a motor 531, a roller 532, a pulley 533, and a wire rope 534. The bottom of the vertical plate 530 is fixedly installed on the inner surface of the packaging machine body 1. The motor 531 is located on the side of the vertical plate 530. The output end of the motor 531 is fixedly installed with the roller 532. The outer surfaces of both ends of the roller 532 are rotatably installed with the inner surface of the vertical plate 530. The side end of the pulley 533 is fixedly installed with the surface of the packaging machine body 1. One end of the wire rope 534 is fixedly installed with the surface of the roller 532, and the other end is fixedly installed with the top surface of the ton bag hanging frame 52. The surface of the wire rope 534 is movably installed with the surface of the middle part of the pulley 533.

[0033] By setting pulley 533, during the process of controlling the contraction and relaxation of wire rope 534 and thus controlling the lifting and lowering of ton bag hanger 52, wire rope 534 will move along the outer surface of the middle part of pulley 533, causing the pulley in pulley 533 to rotate on the two vertical plates, thereby improving the movement effect of wire rope 534.

[0034] The top sides of the lifting feeder 3 are attached to the inner wall of the top of the packaging machine body 1. The lifting feeder 3 is equipped with several lifting screens to support the potato material and transport it to the discharge machine 4 at the top of the packaging machine body 1.

[0035] The controller 2 is electrically connected to the hydraulic cylinder 51, the motor 531, and the electric push rod 61.

[0036] The working process of this utility model is as follows:

[0037] After the worker hooks the handle of the ton bag onto the four spring telescopic hooks 54 at the bottom of the ton bag hanger 52, the excess bag body can be alternately folded below the handle. Then, the folded part is placed between the two sets of clamping arm mechanisms 63. The electric push rod 61 is controlled to retract, which drives the connected movable block 62 to move upward, and drives the connected fixed block 630 to move upward. At the same time, the short connecting rod 631 is pulled upward, and the connected long connecting rod 1 632 rotates around the axis of the position where it is connected to the movable block 62. The long connecting rod 2 633 rotates in parallel at the same time, so that the vertical rod 634 at the end of the two rotates and moves downward and moves closer to the center of the movable block 62. This drives the clamping block 635 connected at the bottom to clamp the folded part of the ton bag. During the potato feeding process, as the lifting platform 50 moves down, the bag gradually unfolds, thus solving the problem that the bottom folds of the ton bag accumulate on the top of the lifting platform 50, which makes it difficult to unfold the ton bag when the potatoes are fed.
