Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a stacking machine, particularly a lifting support assembly for a throwing-type automatic stacking machine. Background Technology

[0002] When bagged and boxed materials (such as flour, grain and oil, building materials, fertilizers, cement, feed, plastics, coal, chemicals, battery materials, dyes and pigments, food and other industries) are packed and loaded onto trucks, manual handling is usually used. This is time-consuming, labor-intensive and inefficient. Although there are some automated loading devices, the conveying can only be done in one direction and the conveying direction cannot be changed at will. As a result, the loading of the whole truck still needs to be done manually. The accuracy of the transfer is low, the speed is slow and the reliability is poor. Therefore, people invented automatic packing machines.

[0003] For example, a Chinese patent document discloses a transportation device and its working method for automatically loading cement bags (application number: 202010751915.1), which includes: a basic component, including a workbench, a first conveying device, and a second conveying device; a loading mechanism, including rollers located on and slidably connected to the horizontal rails, a traveling frame connected to the rollers, and a position adjustment component set on the workbench; the position adjustment component also includes an electric hoist and a hook set on a connecting device, four lifting rails set on the connecting device, a guide part set on the connecting device for limiting the position of the lifting rails, and multiple sets of rotating wheels set on the connecting device, with one end of the hook and one end of the lifting rails both set on the dustproof device. Because the transportation device for automatically loading cement bags lacks a stabilizing mechanism for maintaining stability during lifting, its stability is poor and its lifting is not flexible enough. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a lifting support assembly for a throwing-type automatic stacking bag machine that offers good stability, a compact structure, and flexible operation.

[0005] The purpose of this utility model can be achieved through the following technical solution: a lifting support assembly for a throwing-type automatic stacking machine. The throwing-type automatic stacking machine includes a frame and a translation frame. This lifting support assembly includes a lifting support disposed on the lower side of the translation frame. The translation frame is provided with a lifting mechanism that can drive the lifting support to reciprocate up and down. A stabilizing mechanism that can keep the lifting support stable is provided between the lifting support and the translation frame.

[0006] During operation, the lifting mechanism drives the lifting support to rise and fall to the set position. Since the aforementioned stabilizing mechanism is provided between the lifting support and the translation frame, the lifting support and the translation frame are kept in a stable state. This prevents the lifting support from shaking when it is stationary or rising and falling. It has the advantages of good stability, compact structure, reliable operation and flexible operation.

[0007] In the lifting support assembly of the aforementioned throwing-type automatic bag-stabilizing machine, the stabilizing mechanism includes several sets of linkage mechanisms. Each linkage mechanism includes a first linkage and a second linkage arranged vertically. The lower end of the first linkage is hinged to the upper end of the second linkage, the upper end of the first linkage is hinged to the translation frame, and the lower end of the second linkage is hinged to the lifting support. The stabilizing mechanism using the aforementioned first and second linkages has the advantages of simple structure and good stability.

[0008] In the lifting support assembly of the aforementioned throwing-type automatic bag-stacking machine, the lifting support is equipped with a horizontally arranged conveyor belt, and the linkage mechanism consists of four sets, symmetrically arranged in pairs on both sides of the conveyor belt. This configuration offers advantages such as structural balance and stability, and good connection performance.

[0009] In the lifting support assembly of the aforementioned throwing-type automatic stacking bag machine, a tension spring is provided between the middle of the first connecting rod and the translation frame, with both ends of the tension spring connected to the middle of the first connecting rod and the translation frame, respectively. By setting the aforementioned tension spring, the stabilizing effect and connection strength of the stabilizing mechanism on the lifting support are improved, and the first connecting rod has the advantage of good reset effect.

[0010] In the lifting support assembly of the aforementioned throwing-type automatic bag-stacking machine, the lifting mechanism includes two push-pull frames disposed on both sides of the translation frame. The two push-pull frames can move horizontally reciprocally synchronously. Both ends of each push-pull frame are axially fixed to sprockets, and chains are wound around each sprocket. One end of each chain is fixedly connected to the translation frame, and the other end is fixedly connected to the corresponding end of the lifting support. The horizontal reciprocating movement of the push-pull frames drives the lifting support to rise and fall through the transmission of the sprockets and chains, offering advantages such as compact structure, high transmission efficiency, and reliable and stable operation.

[0011] In the lifting support assembly of the above-mentioned throwing automatic stacking machine, a second sprocket is provided on one side of each sprocket. The second sprocket is axially fixed to the translation frame. The chain passes through the corresponding sprocket and the second sprocket in sequence and is fixedly connected to the lifting support.

[0012] In the lifting support assembly of the aforementioned throwing-type automatic bag-stacking machine, each push-pull frame has a horizontally fixed push-pull rod axially connected to its center. A horizontally fixed rotating shaft and a motor capable of driving the rotating shaft are axially fixed to the translation frame. Worms are fixed to both ends of the rotating shaft. Worm wheels meshing with the worms are axially fixed to the translation frame. The push-pull rod passes through the corresponding worm wheel and is threadedly connected to the worm wheel. The motor drives the worm wheel to rotate via the worm gear transmission. The worm wheel is threadedly connected to the push-pull rod, thus causing the push-pull rod to move horizontally. The lifting support is then raised and lowered via a chain and sprocket. This design offers the advantages of a compact structure and stable operation.

[0013] In the lifting support assembly of the aforementioned throwing-type automatic stacking machine, a horizontally positioned hydraulic cylinder is provided in the middle of the push-pull frame. The cylinder body of the hydraulic cylinder is fixedly connected to the translation frame, and the piston rod of the hydraulic cylinder is fixedly connected to the push-pull frame. The hydraulic cylinder drives the push-pull frame to move horizontally reciprocatingly, offering advantages such as simple structure and reliable operation.

[0014] In the lifting support assembly of the above-mentioned throwing-type automatic stacking machine, the push-pull frame includes two parallel and oppositely arranged fixed plates. The two fixed plates are fixedly connected by two parallel connecting rods. Both ends of the push-pull rod are vertically fixed to the corresponding fixed plates, and the two connecting rods are horizontally symmetrically arranged on both sides of the push-pull rod.

[0015] In the lifting support assembly of the aforementioned throwing-type automatic stacking bag machine, a vertically arranged guide plate is fixedly connected to the translation frame. The guide plate has axially horizontally arranged guide holes that correspond to the connecting rods, which pass through the corresponding guide holes. This arrangement provides better guidance for the translation of the push-pull frame, improving its stability.

[0016] Compared with existing technologies, the lifting support assembly of this throwing-type automatic bag stacking machine has the following advantages:

[0017] 1. The stabilizing mechanism keeps the lifting support and the translation frame stable, preventing swaying when the lifting support is stationary or moving. It has the advantages of good stability, compact structure, reliable operation and flexible operation.

[0018] 2. The stabilizing mechanism adopts four sets of linkage mechanisms consisting of linkage one and linkage two, and the four sets of linkage mechanisms are symmetrically arranged in pairs. The lower end of linkage one is hinged to the upper end of linkage two. The upper end of linkage one is hinged to the translation frame, and the lower end of linkage two is hinged to the lifting bracket. It has the advantages of simple structure, stable structure and good connection effect.

[0019] 3. A tension spring is provided between the middle of rod one and the translation frame. The two ends of the tension spring are connected to the middle of connecting rod one and the translation frame respectively, which improves the stabilizing effect of the stabilizing mechanism on the lifting support and the connection strength, and gives connecting rod one the advantage of good reset effect.

[0020] 4. The horizontal reciprocating movement of the push-pull frame drives the lifting support to rise and fall through the transmission of sprockets and chains. It has the advantages of compact structure, high transmission efficiency and reliable and stable operation. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3 As shown, the lifting support assembly of the throwing automatic stacking machine includes a frame 6 and a translation frame 7. The lifting support 1 assembly includes a lifting support 1 set on the lower side of the translation frame 7. The translation frame 7 is provided with a lifting mechanism 2 that can drive the lifting support 1 to move up and down. A stabilizing mechanism 4 that can keep the lifting support 1 stable is provided between the lifting support 1 and the translation frame 7.

[0027] The stabilizing mechanism 4 includes four sets of linkage mechanisms 4a. Each linkage mechanism 4a includes a first linkage 4a1 and a second linkage 4a2 arranged vertically. The lower end of the first linkage 4a1 is hinged to the upper end of the second linkage 4a2, the upper end of the first linkage 4a1 is hinged to the translation frame 7, and the lower end of the second linkage 4a2 is hinged to the lifting support 1. A tension spring 4a3 is provided between the middle of the first linkage 4a1 and the translation frame 7, with both ends of the tension spring 4a3 connected to the middle of the first linkage 4a1 and the translation frame 7, respectively. Specifically, the lifting support 1 is square, and a horizontally arranged conveyor belt 5 is mounted on the lifting support 1. The four sets of linkage mechanisms 4a are symmetrically arranged in pairs on both sides of the conveyor belt 5.

[0028] The lifting mechanism 2 includes two push-pull frames 2a disposed on both sides of the translation frame 7. The two push-pull frames 2a can move horizontally reciprocally synchronously. Both ends of the push-pull frames 2a are axially fixed to sprockets 2d. Chains 2e are wound around the sprockets 2d. One end of each chain 2e is fixedly connected to the translation frame 7, and the other end of each chain 2e is fixedly connected to the corresponding end of the lifting bracket 1. A second sprocket 2f is provided on one side of each sprocket 2d. The second sprocket 2f is axially fixed to the translation frame 7. The chain 2e passes through the corresponding sprocket 2d and the second sprocket 2f in sequence and is fixedly connected to the lifting bracket 1. A horizontally arranged push-pull rod 2g is axially fixed to the middle of the push-pull frame 2a. A horizontally arranged rotating shaft 2h and a motor 2i that can drive the rotating shaft 2h to rotate are axially fixed to the translation frame 7. Worms 2j are fixed to both ends of the rotating shaft 2h. A worm wheel 2k that meshes with the worm 2j is axially fixed to the translation frame 7. The push-pull rod 2g passes through the corresponding worm wheel 2k and is threadedly connected to the worm wheel 2k.

[0029] Specifically, the push-pull frame 2a includes two parallel and oppositely arranged fixed plates 2b. A sprocket 2d is axially fixed to the fixed plates 2b. The two fixed plates 2b are connected by two parallel connecting rods 2c. Both ends of the push-pull rod 2g are vertically fixed to the corresponding fixed plates 2b, and the two connecting rods 2c are horizontally symmetrically arranged on both sides of the push-pull rod 2g. A vertically arranged guide plate 3 is fixed to the translation frame 7. The guide plate 3 has axially horizontally arranged guide holes that correspond to the connecting rods 2c. The connecting rods 2c pass through the corresponding guide holes, providing a good guiding effect for the translation of the push-pull frame 2a and improving the stability of its movement.

[0030] As another method, a horizontally arranged hydraulic cylinder is provided in the middle of the push-pull frame 2a. The cylinder body of the hydraulic cylinder is fixedly connected to the translation frame 7, and the piston rod of the hydraulic cylinder is fixedly connected to the push-pull frame 2a. The push-pull frame 2a is driven to move horizontally and reciprocally through the hydraulic cylinder, which has the advantages of simple structure and reliable operation.

[0031] During operation, the motor 2i drives the worm gear 2k to rotate through the transmission of the worm 2k and worm 2j. The worm gear 2k is threadedly connected to the push-pull rod 2g, thereby driving the push-pull rod 2g to move horizontally, which in turn drives the push-pull frame 2a to move horizontally. Through the transmission of the sprocket 2d and chain 2e, the lifting bracket 1 is raised or lowered to the set position. Since a stabilizing mechanism 4 is provided between the lifting bracket 1 and the translation frame 7, the stabilizing mechanism 4 adopts a linkage assembly composed of four sets of connecting rods 4a1 and 4a2. A tension spring 4a3 is provided between the connecting rod 4a1 and the translation frame 7, which improves the stability and connection strength of the lifting bracket 1. This ensures that the lifting bracket 1 can avoid shaking when stationary or when raising or lowering. It has the advantages of good stability, compact structure, reliable operation, and flexible operation.
