[0055] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0056] Please refer to the accompanying drawings Figure 12 and the accompanying drawings Figure 13 .

[0057] The application discloses a material pouring hopper device, which comprises a material pouring hopper 941 used for receiving the material. The bottom of the material pouring hopper 941 is provided with a screw hole used for connecting with a turnover plate 9301 (external equipment). The inside of the material pouring hopper 941 is provided with a push plate 942 movably connected to the hopper wall of the material pouring hopper 941. The hopper wall of the material pouring hopper 941 is further provided with a driving part used for driving the push plate 942, and the output end of the driving part is connected with the push plate 942. A plurality of push plates 942 are uniformly distributed along the circumference of the material pouring hopper 941. Under the driving of the driving part, the plurality of push plates 942 are gathered to the center of the material pouring hopper 941 or are scattered to the periphery of the material pouring hopper 941.

[0058] After the material falls into the material pouring hopper 941, the plurality of push plates 942 are driven by the driving part to gather to the center of the material pouring hopper 941, so as to clamp the material in the material pouring hopper 941. Then, the turnover plate 9301 drives the material pouring hopper 941 to turn over. After the turnover plate 9301 is turned to a preset inclination angle, the plurality of push plates 942 are driven by the driving part to scatter to the periphery of the material pouring hopper 941, so as to release the clamping of the material. Then, the material can fall along the inclined material pouring hopper 941 to a designated equipment under the action of gravity.

[0059] The application forms effective control on the material through the driving part and the push plate 942, can avoid the material from falling randomly in the turning process, ensures that the material falls into the designated equipment according to the preset target, and improves the operation quality and operation efficiency of the turnover material pouring device.

[0060] When the plurality of push plates 942 gather to the center of the material pouring hopper 941, the plurality of push plates 942 can be enclosed into a closed structure, and the material is enclosed in the closed structure formed by the push plates 942, so that when the turnover plate 9301 is turned to a preset inclination angle, the material can be effectively prevented from entering the back of the push plate 942 or being clamped by the push plate 942, thereby further improving the operation quality of the automatic turnover and material pouring device.

[0061] It should be noted that in the actual processing process, the size of the push plate 942 is designed by comprehensively considering the volume of the material and the stroke of the push plate 942, so that the plurality of push plates 942 can be enclosed into a closed structure.

[0062] The driving part is preferably a pneumatic cylinder 943, and the pneumatic cylinder 943 has high operation precision. Each pneumatic cylinder 943 is used to drive one push plate 942.

[0063] The pneumatic cylinder 943 is arranged outside the hopper wall of the material pouring hopper 941, and the piston of the pneumatic cylinder 943 penetrates the hopper wall of the material pouring hopper 941 to be connected with the corresponding push plate 942. The pneumatic cylinder 943 is connected to the hopper wall through a fixed plate group. The fixed plate group includes an angle plate 9441 and a support plate 9442. One part of the angle plate 9441 is attached and fixed to the hopper wall of the material pouring hopper 941, and the other part is attached and fixed to the upper surface of the pneumatic cylinder 943, so that the connection between the pneumatic cylinder 943 and the material pouring hopper 941 is realized through the angle plate 9441. In order to ensure the structural strength of the angle plate 9441, the angle plate 9441 in the application further includes a reinforcing plate, one side of the reinforcing plate is connected with a part of the angle plate 9441, and the other side of the reinforcing plate is connected with another part of the angle plate 9441.

[0065] The upper part of the push plate 942 extends out of the pouring hopper 941, and the upper part of the push plate 942 has an outwardly inclined inclined part 9421 along the radial direction of the pouring hopper 941. Since the upper part of the push plate 942 extends out of the pouring hopper 941, the push plate 942 can still form a pushing action on the material even if the material in the pouring hopper 941 spills out of the opening of the pouring hopper 941. The flared part 9421 of the upper part of the push plate 942 facilitates the material to fall into the pouring hopper 941. In addition, when the pouring hopper 941 is at a preset inclination angle, the outwardly inclined inclined part 9421 guides the outflow of the material.

[0082] Please refer to the accompanying drawings Figure 2 - the accompanying drawings Figure 5 .

[0083] The vacuum breaking device 5 further comprises a vacuum breaking rack 51 and a vacuum breaking lifting assembly 52. The vacuum breaking lifting assembly 52 is arranged on the vacuum breaking rack 51, and the piston of the vacuum breaking lifting assembly 52 faces downward, and the bag grabbing assembly is connected with the piston. The needle assembly 53 is arranged on the side of the vacuum breaking rack 51. After the bag material on the mesh belt line 1 is grabbed by the bag grabbing assembly and rises with the piston of the vacuum breaking lifting assembly 52, the needle 531 extends to pierce the bag material.

[0084] The vacuum breaking lifting assembly 52 in the application comprises a lifting cylinder 521. The vacuum breaking rack 51 comprises a top mounting plate 511, and the lifting cylinder 521 is mounted on the top mounting plate 511 of the vacuum breaking rack 51.

[0085] The vacuum breaking device 5 in the application can adopt the adsorption mode to grab the bag material. Specifically, the bag grabbing assembly can be a suction cup assembly 56. The suction cup assembly 56 comprises a suction cup 562 and a suction cup connecting plate 561. The suction cup 562 is connected to the suction cup connecting plate 561. The piston end of the lifting cylinder 521 is connected with a piston connecting plate 522, and the suction cup connecting plate 561 and the piston connecting plate 522 are connected with each other, so as to realize the connection between the piston of the vacuum breaking lifting cylinder 521 and the suction cup 562. The suction cup 562 is used for adsorbing the bag material. The bag material is grabbed in the adsorption mode, which can avoid damaging the bag material.

[0086] The limiting assembly 54 comprises a linear bearing 543, a lifting shaft 541 and a limiting ring 542.

The lifting shaft 541 is clearance fitted in the linear bearing 543. The diameter of the limiting ring 542 is larger than the inner diameter of the linear bearing 543. During the process that the lifting cylinder 521 drives the suction disc assembly 56 to descend, if the limiting ring 542 touches the upper end of the linear bearing 541, the lifting cylinder 521 cannot continue to move downward. Thus, the suction disc assembly 56 can be ensured to descend to the preset position, so as to facilitate the adsorption of the bag below.

[0087] Further, the limiting ring 542 and the lifting shaft 541 in the present application are detachably connected, and the height of the limiting ring 542 can be adjusted according to the specific size of the bag, so as to ensure that the suction disc assembly 56 descends to the appropriate position. Thus, the flexibility of the vacuum breaking device 5 is improved.

[0088] The limiting ring 542 can be detachably connected with the lifting shaft 541 through bolts.

[0089] It should be noted that the lifting shaft 541 is fitted in the linear bearing 543. Since the inner ring of the linear bearing 543 is rotatable relative to the outer ring, the friction between the lifting shaft 541 and the inner ring of the linear bearing 543 is greatly reduced. The bottom of the linear bearing 543 is provided with a flange plate, and the linear bearing 543 is fixed on the top mounting plate 511 of the vacuum breaking frame 51 through the flange plate. The flange plate is provided with bolt holes, and the bolts matched with the bolt holes are screwed into the top mounting plate 511, so as to lock the flange plate on the back of the top mounting plate 511. The linear bearing 543 penetrates through the top mounting plate 511 and extends upward from the top mounting plate 511. Based on the consideration of balance limiting, the present application provides a plurality of limiting assemblies 54, and the plurality of limiting assemblies 54 are uniformly distributed around the lifting cylinder 521.

In this way, the height of the piercing needle assembly 53 can be adjusted by adjusting the vertical plate 537 up and down, so as to ensure that the piercing needle assembly 53 adapts to different working conditions. After the vertical plate 537 is adjusted in place, the bolt is screwed into the appropriate position of the waist-shaped hole to lock the vertical plate 537 on the top mounting plate 511 of the vacuum breaking frame 51.

[0096] Further, the waist-shaped hole is provided with two left and right ones to improve the balance and firmness of the connection between the cylinder connecting plate and the top mounting plate 511 of the vacuum breaking frame 51.

That is, the pouring hopper device 94 can fix the bag material and also can release the fixation of the bag material. The pouring hopper 94 is fixedly connected with the turnover plate 9301. The releasable fixation of the bag material by the pouring hopper device 94 can refer to the operation principle of the pouring hopper device 94 described above, which will not be repeated here.

[0102] The turnover shaft 9303 is connected to the edge of one side of the turnover plate 9301, and the two ends of the turnover shaft 9303 are hinged on the mounting frame. The driving assembly 9311 is fixedly connected to the mounting frame, the output shaft of the driving assembly 9311 is connected with the turnover shaft 9303, and the driving assembly 9311 is used to drive the turnover shaft 9303 to rotate. When the driving assembly 9311 drives the turnover shaft 9303 to rotate in one direction, the turnover plate 9301 realizes turnover pouring. When the driving assembly 9311 drives the turnover shaft 9303 in the other direction, the turnover plate 9301 resets.

[0103] The output end of the pouring lifting assembly 92 is connected with the mounting frame, and the pouring lifting assembly 92 drives the mounting frame to ascend or descend, in other words, the pouring lifting assembly 92 drives the turnover assembly 93 to ascend or descend.

[0104] In the present application, the bag material is first locked in the pouring hopper device 94, then the turnover assembly 93 is driven by the pouring lifting assembly 92 to ascend to a preset position, and then the driving assembly 9311 drives the turnover shaft 9303 to rotate in one direction to make the turnover plate 9301 turn over. After the turnover plate 9301 turns over to a preset angle, the fixation of the bag material is released, and then the inner material in the bag material automatically falls into the mobile pouring device 10 under the action of gravity. Then the driving assembly 9311 drives the turnover shaft 9303 in the opposite direction to make the turnover plate 9301 reset. Finally, the pouring lifting assembly 92 drives the turnover assembly 93 to descend to reset, to enter the next turnover pouring period.

[0105] A material sensor 9314 is arranged on the turnover plate 9301 and used to detect whether there is material in the pouring hopper 941. The present application is provided with a through hole 946 on the bottom plate 913 of the pouring hopper 941, which is opposite to the material sensor 9314 on the turnover plate 9301. The material sensor 9314 can be a photoelectric sensor or a pressure sensor. If the material sensor 9314 detects that the pouring hopper 941 is placed with material, the material sensor 9314 will trigger the controller to send a control signal to the pouring lifting assembly 92 to control the pouring lifting assembly 92 to output an upward displacement, so as to drive the turnover assembly 93 to rise to a preset position for pouring.

[0106] In order to facilitate the installation of the material sensor 9314, the present application is provided with a hollow structure on the turnover plate 9301, and an installation protrusion 9313 is arranged in the hollow structure, and the material sensor 9314 is installed on the installation protrusion 9313. The hollow structure provides an operation space for the installation of the material sensor 9314, and reduces the weight of the turnover plate 9301. As described above, a second suction cup 9452 can be arranged on the bottom plate 913 of the pouring hopper 941, and a pipe corresponding to the second suction cup 9452 can pass through the hollow structure to be connected to other related equipment.

The turnover shaft 9303 penetrates the shaft connecting parts 9302 on the two turnover side plates 93012 in sequence, and the turnover shaft 9303 is fixedly connected with the turnover side plates 93012. In the application, the turnover shaft 9303 only needs to be assembled with the shaft connecting parts 9302 of the two turnover side plates 93012, and does not need to be assembled with the turnover main plate 93011, thereby significantly reducing the assembly difficulty of the turnover plate 9301 and the turnover shaft 9303.

[0137] In the process of using the bag cutting device provided in this specific embodiment, firstly, the rodless cylinder 8211 drives the truss 8205 to move to a suitable position, the lifting power component 8215 drives the cutter 8218 to rise and fall to a suitable height, the telescopic power component 8217 extends the cutter 8218 to a position where it can cut the flexible packaging bag, and the cutter sensor 8219 detects the cutter 8218; the sliding power component 8216 drives the cutter 8218 to move, thereby cutting the flexible packaging bag.

[0138] In one specific embodiment, the bag-carrying device 83 includes: a lifting module 8301, which is installed on the mobile device 82;

[0139] The tensioning component is installed on the lifting module 8301 and is driven to lift by the lifting module 8301; the tensioning component is used to tension the bag material.

[0140] like Figure 18 As shown, the lifting module 8301 includes a servo motor 8311, which is connected to the tensioning component through a transmission component and drives the tensioning component to lift as a whole. The servo motor 8311 is connected to the mounting bracket 8207 set on the truss 8205 through the lifting module connecting plate 8312.

[0141] The tensioning assembly comprises a support plate 8302 fixedly installed on the lifting module 8301, a tensioning plate 8303 movable relative to the support plate 8302 to approach or move away from the support plate 8302, and a tensioning driving component 8304 for driving the tensioning plate 8303 to lift or lower, so that the tensioning plate 8303 can tension or release the bag material to the support plate 8302, and the tensioning driving component 8304 is installed on the lifting module 8301.

[0142] As shown in Figure 19 The tensioning assembly further comprises a driving component mounting plate 8305 for mounting the tensioning driving component 8304, the driving component mounting plate 8305 is provided with a linear bearing 8306, and the tensioning plate 8303 is connected with a cylindrical shaft 8307 matched with the linear bearing 8306; during the lifting and lowering of the tensioning plate 8303 driven by the tensioning driving component 8304, the cylindrical shaft 8307 moves along the linear bearing 8306, which can effectively prevent the tensioning plate 8303 from tilting during the lifting and lowering process, and ensure that the bag material can be tensioned.

[0143] The driving component mounting plate 8305 is oppositely arranged with the support plate 8302, and at least one of the driving component mounting plate 8305 and the support plate 8302 is provided with a detection sensor for detecting the position of the bag material and a sensor mounting plate 8310 for mounting the detection sensor; the detection sensor can be a through-beam sensor, the transmitter 8308 of the through-beam sensor is mounted on the lower part of the support plate 8302, the receiver 8309 of the through-beam sensor is mounted on the upper part of the driving component mounting plate 8305, and the driving component mounting plate 8305 and the support plate 8302 are both provided with through holes for transmitting the signal emitted by the transmitter 8308 to the receiver 8309.

[0144] The operation process of the automatic bag cutting and material pouring system in the application is as follows: the bag material moves to the spraying device 2 along the web belt line 1, and the spraying device 2 starts to spray alcohol on the bag material. Then the bag material enters the air shower device 4 along the web belt line 1 to receive air shower. After the air shower, the bag material enters the vacuum breaking device 5 along the web belt line 1.

[0145] The piston of the lifting cylinder 521 extends and drives the suction cup 562 to approach the bag material at the vacuum breaking device 5. After the limiting ring 542 touches the upper end of the linear bearing 543, the piston of the lifting cylinder 521 stops descending. The suction cup 562 generates negative pressure to adsorb the bag material. The piston of the lifting cylinder 521 retracts to lift the bag material. After the lifting cylinder 521 returns to the initial position, the piston of the needle cylinder 535 extends to drive the needle 531 to pierce the bag material to break the vacuum of the bag material. The piston of the needle cylinder 535 retracts. The piston of the lifting cylinder 521 extends to lower the bag material. After the limiting ring 542 touches the upper end of the linear bearing 543, the piston of the lifting cylinder 521 stops descending. The suction cup 562 releases the adsorption force on the bag material, and the bag material returns to the web belt line 1.

[0146] The bag material then passes through the lower brush device 6 and the upper brush device 7 in turn, so as to unfold the bag opening of the bag material. Then the bag material moves to the bag cutting device 8 along with the webbing line 1.

[0147] At the bag cutting device 8, when the detection sensor on the driving member mounting plate 8305 or the support plate 8302 senses the bag opening, the bag material stops moving, the tensioning driving component 8304 drives the tensioning plate 8303 to move downward, the tensioning plate 8303 cooperates with the support plate 8302 to tension the bag opening, the servo motor 8311 in the lifting module 8301 moves to drive the tensioning assembly to rise, thereby driving the bag material to rise to a suitable height, at the same time, the rodless cylinder 8211 of the moving device 82 drives the truss 8205 to move to the designated inverted material hopper device, at this time, the bag material is still in the tensioning state, the slide cylinder in the cutter assembly 8200 drives the cutter 8218 to extend, the slide driving member 8216 drives the extended cutter 8218 to move, and the bag cutting is completed.

[0148] The cut bag material falls into the inverted material hopper 941 below. The cylinder 943 in the inverted material hopper device 9 drives the push plate 942 to gather to the center of the inverted material hopper 941, so as to enclose and form a clamping force on the bag material. Then the first suction cup 945 and the second suction cup 9452 are controlled to generate suction force to suck the bag material.

[0149] Then the inverted material lifting assembly 92 drives the turnover assembly 93 and the inverted material hopper device 94 to rise to a preset height, then the motor 9310 drives the turnover plate 9301 to turn over, after the turnover plate 9301 turns over to a preset inclination angle, the first suction cup 9451 is controlled to release the suction force first, so as to release the suction of the bag material, then the push plate 942 is controlled by the cylinder 943 to spread to the periphery of the inverted material hopper 941, so as to release the clamping force on the bag material, then the inner material in the bag material will slide out from the inclined inverted material hopper 941 under the action of its own gravity, and fall into the moved material hopper device 10. Finally, the inverted material hopper 941 is reset with the turnover plate 9301, to prepare for the next turnover and inverted material period.
