Description

Technical Field

[0001] The invention relates to the technical field of bag openers, in particular to a fully automatic bottom-breaking ton bag opener and a working method thereof. Background Art

[0002] In the preparation process of lithium battery electrode sheets, the powdered raw materials used are mostly packaged in ton bags. In the actual production process, a bag opener is used to open the ton bags to collect and store the powder in the ton bags. The bag opener is mostly composed of a frame, a lifting device and a cutter. The lifting device is used to lift and transport the ton bags, and the cutter is used to cut the ton bags to allow the materials inside the ton bags to leak out.

[0003] The bag opening machine in the prior art has a relatively simple structure and has the following disadvantages:

[0004] (1) Low degree of automation, usually using a semi-automatic and semi-manual production method, requiring manual operations such as hanging, unloading, and taking out ton bags, resulting in low work efficiency;

[0005] (2) Poor sealing performance causes powder to leak into the production site, resulting in material waste, affecting the 5S management of the production site, and affecting the occupational health of operators;

[0006] (3) The quality of the powder after unpacking is low. Metal shavings will be generated during the movement of the packing machine movement mechanism. The metal shavings will fall into the powder, which will reduce the quality of the powder and affect the quality of the electrode sheets produced later.

[0007] (4) The cutting efficiency of the tool is low. The bag opening knife often uses a cross tool. When it breaks the multi-layer ton bag, the tearing area is small, leaving a large amount of residual material in the ton bag, which is difficult to discharge. It needs to be manually beaten to discharge the material, and the ton bag debris will fall into the powder, polluting the powder;

[0008] (5) The waste bag collection efficiency is low. After the powder is put into the bag, it is necessary to manually remove the bag, which is cumbersome and may cause secondary leakage of the powder in the waste bag. Summary of the invention

[0009] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a fully automatic bottom-breaking ton bag opening machine and a working method thereof. By adopting fully automatic production equipment and production methods, it is possible to effectively improve production efficiency, prevent material leakage, and improve product quality.

[0010] The technical solution adopted by the present invention is as follows:

[0013] A conveying device is installed in the conveying cavity, the working end of the conveying device extends into the working cavity and is connected to a bag hanging device, and a ton bag is hung on the bag hanging device;

[0014] A package opening knife device is installed in the package opening cavity;

[0015] A bag collecting device for collecting waste bags is installed in the discharge cavity;

[0016] The conveying device drives the bag hanging device to move linearly in the horizontal direction, thereby driving the ton bag to pass through the feeding cavity, the bag opening cavity and the discharging cavity in sequence;

[0017] The conveying device drives the bag hanging device to move linearly in the vertical direction, so that the bag opening knife device cuts the bottom of the ton bag.

[0018] As a further improvement of the above technical solution:

[0019] A top plate assembly is installed in the main body of the equipment, and the top plate assembly is sealed and installed with the conveying device through a sealing cover;

[0020] The top plate assembly and the sealing cover divide the internal space of the equipment body into a conveying chamber and a working chamber which are isolated from each other.

[0021] The bag hanging device comprises a bag hanging top frame and several locking mechanisms, a hanging ring is fixed at the top center of the bag hanging top frame, several bag hanging cylinders arranged evenly at intervals are fixed on the top of the bag hanging top frame, the output end of a single bag hanging cylinder is connected to a bag hanging swing arm, and a single bag hanging swing arm is hinged to the bag hanging top frame;

[0022] A single locking mechanism is installed below the side of a single bag hanging swing arm;

[0023] When the bag hanging cylinder is extended or retracted, the corresponding bag hanging swing arm is driven to rotate, thereby driving the corresponding bag hanging swing arm to move on the surface of the ton bag, and then the bag hanging swing arm passes through the side sling arranged on the outer side of the ton bag.

[0024] The single locking mechanism includes a locking hole provided on the lower side end surface of the single bag hanging swing arm, and a locking mounting frame fixed below the side wall surface of the single bag hanging swing arm;

[0025] A locking cylinder is fixed on the locking mounting frame, an output end of a single locking cylinder is connected to a locking pin, and a single locking pin corresponds to a single locking hole;

[0026] The locking cylinder drives the corresponding locking pin to be inserted into the locking hole, thereby preventing the side sling from falling off the corresponding bag hanging swing arm.

[0027] A single locking cylinder is arranged above the corresponding locking hole, and an output end of the single locking cylinder is connected to the corresponding locking pin through a connecting pin, so that the locking pin corresponds to the locking hole.

[0028] The structure of the conveying device is as follows: it includes a first guide rail fixed on the frame, a first guide seat is mounted on the first guide rail, a first motor is fixed on one side of the first guide seat, an output end of the first motor is connected to a first driving wheel group rotatably mounted inside the first guide seat, a first driven wheel group symmetrically arranged with the first driving wheel group is also mounted inside the first guide seat, the first motor drives the first driving wheel group to rotate, thereby driving the first guide seat to move linearly along the first guide rail;

[0029] A second guide rail is fixed at the bottom of the first guide seat, and the second guide rail is mounted in cooperation with the second guide seat through a second driving wheel group and a second driven wheel group. The second driving wheel group is connected to an output end of a second motor fixed on the second guide seat, and the second motor drives the second driving wheel group to rotate, so that the second guide seat moves linearly along the second guide rail.

[0030] The second guide rail is arranged in parallel with the first guide rail;

[0031] An electric hoist is installed at the bottom of the second guide seat. The output end of the electric hoist is connected to a hook. The electric hoist suspends the bag hanging device through the hook, thereby driving the bag hanging device to move linearly in the vertical direction.

[0032] The structure of the bag collecting device is as follows: it includes two bag collecting cylinders arranged at intervals, the output end of a single bag collecting cylinder is connected to a mounting seat, a pull-out guide rail is fixed on the top of the single mounting seat, and a plurality of pull-out guide sliders are mounted on the single pull-out guide rail, and the pull-out guide sliders are fixed to the outer surface of a bag collecting box, and the bag collecting box is located between the two bag collecting cylinders. An opening is provided on the top of the bag collecting box, and the ton bags that have been discharged are placed in the opening. A pressing plate is mounted on the frame above the opening, and the two bag collecting cylinders are extended or retracted at the same time, thereby driving the bag collecting box to make a linear motion in the vertical direction through the mounting seat, and then compressing the ton bags in the bag collecting box through the pressing plate.

[0033] The equipment body comprises a frame, on which an outer cover is mounted. When the third automatic door is closed, the outer cover isolates the inner space of the frame from the external environment.

[0034] A dust removal system is installed on the outer wall surface of the outer cover to collect dust inside the conveying cavity.

[0035] A working method of the fully automatic bottom-breaking ton bag opening machine based on the above-mentioned method comprises the following steps:

[0036] S1. When the radar on the third automatic door senses the incoming material, the third automatic door opens, allowing the ton bag to enter the feeding chamber. After the feeding is completed, the third automatic door closes;

[0037] S2. The conveying device drives the bag hanging device to move linearly in the horizontal direction, so that the bag hanging device enters the feeding chamber. Then, the conveying device drives the bag hanging device to move linearly downward in the vertical direction, so that the bag hanging device lifts the ton bag. Then, the conveying device drives the bag hanging device to move linearly upward in the vertical direction.

[0038] S3. After the conveying device lifts the ton bag into place through the bag hanging device, the second automatic door opens, and the conveying device drives the ton bag to move linearly in the horizontal direction through the bag hanging device, so that the ton bag enters the bag opening chamber;

[0039] S4. After the ton bag is loaded into the bag opening chamber, the second automatic door is closed, and then the conveying device drives the ton bag to move downward in a straight line along the vertical direction through the bag hanging device, so that the bag opening knife device cuts the bottom of the ton bag, and then the material in the ton bag flows out;

[0040] S5. After the material in the ton bag is discharged, the conveying device drives the ton bag to move in a straight line in the vertical direction through the bag hanging device. After rising to the right position, the first automatic door opens, and the conveying device drives the ton bag to move in a straight line in the horizontal direction through the bag hanging device, so that the ton bag leaves the bag opening chamber and enters the discharge chamber;

[0041] S6. After the ton bag is loaded into the discharge chamber, the first automatic door is closed, and then the conveying device drives the ton bag to move downward in a vertical direction through the bag hanging device, so that the bottom end surface of the ton bag contacts the bottom wall of the bag collecting box of the bag collecting device;

[0042] S7. Subsequently, the locking pin of the bag hanging device comes out of the locking hole, so that the big bag falls off the bag hanging device and falls into the bag collecting box;

[0043] S8. Then, the bag collecting cylinder of the bag collecting device extends out, driving the bag collecting box to rise and make a linear motion close to the pressing plate, thereby compressing the ton bag through the pressing plate. After the compression is completed, the bag collecting cylinder retracts, driving the bag collecting box back to its original position;

[0044] S9. Finally, when the number of ton bags collected in the bag collecting box reaches the set number, the bag collecting box is taken away by the AGV vehicle.

[0045] The beneficial effects of the present invention are as follows:

[0046] The present invention has a compact and reasonable structure and is easy to operate. By arranging a fully automatic bottom-breaking ton bag opening machine, ton bags can be fully automatically opened to realize unmanned production. The opening efficiency is high, thereby greatly improving production efficiency, and the quality of powder after opening is high; at the same time, it can prevent material leakage, thereby avoiding material waste.

[0047] The present invention also has the following advantages:

[0048] (1) The present invention provides a bag hanging device, which can automatically identify the side sling position of the ton bag, realize full-automatic strap hanging and strap removal, and thus improve work efficiency.

[0049] (2) In the present invention, by setting three automatic doors, the working chamber can be divided into three mutually isolated chambers. The discharge chamber and the feed chamber are respectively located on both sides of the package opening chamber, thereby forming a secondary seal for the package opening chamber, ensuring the full sealing of the package opening chamber, ensuring that there is no dust leakage in the package opening machine, reducing material waste, facilitating 5S management at the production site, and ensuring the occupational health of operators.

[0050] (3) In the present invention, by providing a top plate assembly and a sealing cover, mutual isolation between the conveying chamber and the working chamber can be achieved, effectively preventing metal chips in the conveying device from falling into the unpacking chamber, thereby ensuring the quality of the powder and improving the quality of the electrode sheets obtained in subsequent production.

[0051] (4) The present invention provides a bag opening knife device which adopts an annular knife head and a conical blade and adopts a bottom bag breaking method. After the blade cuts the ton bag, the material in the ton bag can flow out from the annular knife head. The cutting efficiency is high and the tearing area is large, thereby ensuring that the ton bag can be fully discharged.

[0052] (5) The present invention provides a bag collecting device to automatically collect waste bags after the powder is put into the waste bag, thereby effectively improving the waste bag collection efficiency; at the same time, the waste bag collection process is carried out in the discharge chamber, which can prevent the powder in the waste bag from leaking to the production site.

The feeding chamber, the bag opening chamber and the discharging chamber are arranged in sequence in the horizontal direction, and the first automatic door 1 is installed at the feeding port of the feeding chamber, and the first automatic door 1 isolates the feeding chamber from the external environment; because the powder leakage in the bag opening chamber is the most serious, the discharging chamber and the feeding chamber are arranged on both sides of the bag opening chamber, so as to achieve a full sealing effect of the bag opening chamber, and the sealing performance is good, which can effectively prevent the leakage of materials in the bag opening machine;

[0072] The main body of the equipment includes a frame 10, on which an outer cover 4 is installed. When the third automatic door 3 is closed, the outer cover 4 isolates the internal space of the frame 10 from the external environment. The outer cover 4 is also provided with an observation window for conveniently observing the operation of the bag opener. A dust removal system 12 is installed on the outer wall of the outer cover 4 to collect debris inside the conveying chamber.

[0073] A top plate assembly 13 is installed in the main body of the equipment. The top plate assembly 13 is sealed and installed with the conveying device 6 through a sealing cover 11. In one embodiment of the present invention, the sealing cover is set as an accordion cover. In other embodiments, any cover that can mainly achieve a sealing function can be used. In the present invention, the top plate assembly 13 and the sealing cover 11 isolate the conveying chamber from the working chamber, thereby preventing the metal grinding chips generated by the conveying device 6 in the conveying chamber during its movement from falling into the working chamber. In addition, in order to further improve its protective effect, the sealing cover 11 is installed on the outer side wall of the electric hoist 603 in the conveying device 6.

[0074] A dust removal system 12 is installed on the outer wall of the outer cover 4. The dust removal system 12 collects dust inside the conveying chamber. The dust includes metal chips. Since the metal chips will cause defects such as short circuit failure in the subsequently prepared electrode sheets, it will have a great impact on the quality of the lithium battery. By setting up the dust removal system 12, the metal chips can be collected and processed in time, thereby ensuring the quality of the powder after unpacking.

[0075] A conveying device 6 is installed in the conveying cavity, and the working end of the conveying device 6 extends into the working cavity and is connected to the bag hanging device 5.
