Description

[0001] The present invention relates to the technical field of material packaging, and in particular to a weight-controlled fixed-length compression bagging machine suitable for cloud operation and a control method thereof. Background Art

[0002] Currently, workshops generally use hydraulic balers to squeeze various materials (such as steel shavings, scrap steel, scrap aluminum, scrap copper, scrap stainless steel and other waste materials) into various shapes such as cuboids, octagons, cylinders, etc., and then transport the extruded materials, which can save transportation space and reduce transportation costs.

[0003] Existing balers mainly adopt a structural design in which weighing and processing are separated. The materials need to be weighed first and then sent to the compression chamber. However, there are often weight requirements for the compressed baling blocks. Obviously, the current feeding method will cause material loss during transportation, resulting in a certain weight difference between the compressed material and the material at the time of actual weighing. Although a small number of balers combine weighing and processing in their design, the unreasonable design of the weighing structure will still affect the compressed weight of the baling blocks. This is mainly manifested in the batch processing and compression process, where the materials are prone to adhere to the inner wall of the weighing bin, greatly affecting the weight and compressed size of the final baling blocks.

It can accurately control the weight of each material bag and improve the consistency of batch production of bags.

[0034] 3. The present invention can improve the material unloading speed through the structural design of the inverted ladder-shaped bin of the unloading bin, and through the design of the window, it can be convenient for the operator to observe the unloading situation and grasp the unloading progress.

[0035] 4. The present invention can achieve compression of materials in the horizontal direction through the design of a horizontal fixed-length compression mechanism. Specifically, through the design of a compression movable beam position measurement control component, the compression distance of the horizontal compression movable beam can be accurately controlled to ensure the horizontal compression size of the material; and through the design of a vertical fixed-length compression mechanism, the material can be compressed in the vertical direction. Here, through the design of a vertical compression movable beam position measurement control component, the compression distance of the vertical compression movable beam can be accurately controlled to ensure the vertical compression size of the material.

[0036] 5. The present invention adopts the gate structure design of the gate mechanism.

[0037] 6. The present invention can automatically push out the formed bales through the design of the bale pushing mechanism, thereby reducing the cost of manual pushing and improving the speed of automatic bale discharging. Moreover, the design of the push-out movable beam position control component can accurately control the reciprocating distance of the push-out movable beam, thereby improving the accuracy of the material compression size and the accuracy of bale discharging.

[0038] 7. The vertical compression movable beam of the present invention includes a vertical baffle and a horizontal pressure plate which are fixedly connected in sequence, wherein the vertical baffle is close to the feed chamber and is vertically arranged with the horizontal pressure plate, and the height of the vertical baffle is higher than the height of the compression chamber. The end of the feed chamber can be blocked by the vertical baffle during vertical compression to prevent the material from entering the feed chamber during vertical compression, thereby improving the compression efficiency. Combined with the design that the bottom of the compression chamber is lower than the bottom of the feed chamber, it is convenient to push the material after preliminary compression into the compression chamber, and the size control of the package can be achieved more accurately. Specifically, because the bottom length and width of the compression chamber are fixed sizes, the problem of too loose or too tight caused by inaccurate control of the pushing position of the horizontal compression end can be avoided, thereby improving the accuracy of the size of the finished package.

At the same time, the vertical compression instruction in step S6 is to control the vertical compression end to move back and forth up and down in the compression chamber 13, and according to the set vertical compression stroke, the vertical compression length is achieved.

[0078] Of course, if you want to compress materials in batches, you can close the door after the materials in the weighing bin are unloaded, and carry out a new round of material weighing. After the vertical compression and sizing are completed, you can unload the next batch of materials, which can improve the continuity of material production.

[0080] The data central processor can perform parameter calculation on the data collected by the data acquisition system and compare it with the program target value, and at the same time run the corresponding instructions of the instruction set according to the comparison results, and send them to the action execution relays of the weighing and feeding mechanism, the horizontal fixed-length compression mechanism, the vertical fixed-length compression mechanism, the gate mechanism, and the bag pushing mechanism and the control switches on the corresponding control panel, so as to ensure that each mechanism of the weight-controlled fixed-length compression bagging machine suitable for cloud operation is either in a working state or in a standby state waiting for work, that is, in a standby position;

[0081] The operation instruction set contains all the action instructions to ensure the controlled operation of the weight-controlled fixed-length compression bagging machine; the action relays and control switches execute the operation instructions issued by the central processor, and perform various operation controls such as starting, stopping, and maintaining the status of each functional module of the weight-controlled fixed-length compression bagging machine suitable for cloud operation. Among them, the Internet of Things communication complies with the SO standard communication protocol, accepts remote control instructions from the service users of the weight-controlled fixed-length compression bagging machine, and runs the operation instructions of the entire domain and the ecological chain. At the same time, it can also send real-time status parameters of the weight-controlled fixed-length compression bagging machine suitable for cloud operation to relevant parties in the entire domain operation ecological chain as needed; electrical safety protection not only includes conventional necessary safety protection functions, but also includes various safety locks of the weight-controlled fixed-length compression bagging machine suitable for cloud operation, which comprehensively guarantees the safe operation of the weight-controlled fixed-length compression bagging machine suitable for cloud operation regardless of whether it is manned or remotely operated.
