Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and particularly relates to a ton bag packaging machine. Background Art

[0002] As a large-scale packaging equipment integrating electronic weighing, automatic bag discharging and high-efficiency dust removal functions, the ton bag packaging machine is designed to meet the ton bag packaging requirements of bulk materials. It is famous for its highly automated operation, accurate packaging precision, adjustable packaging speed and excellent structural design, and is widely used in many industrial fields such as minerals, chemicals, building materials, grains and feeds.

[0003] However, in actual application, the ton bag cannot be fully unfolded during filling, resulting in low space utilization rate of the ton bag. And during the filling process, the filling port is not sealed, causing dust to disperse in the environment. Also, due to the loose powder materials, the ton bag needs to move up and down to compact the materials. Moreover, because the powder materials are loose, voids appear in the received materials, and the looseness of the materials fails to reach the specified weight, which is also likely to cause problems such as the toppling of the bagged items during discharging. In addition, the existing bag clamping mechanism cannot clamp the bag mouth well, easily causing dust leakage, poor clamping stability and easy damage to the bag mouth, etc. Content of the Utility Model

The bag clamping mechanism forms a structure of a clamp, clamping the bag mouth on the bag clamping cylinder. The clamping and sealing effects are good, and the design of the fixed shaft is added, enabling the clamping frames on both sides to expand and contract synchronously, avoiding misalignment during clamping, resulting in incomplete sealing or even damage to the bag mouth. During the loading process, due to reasons such as material adhesion and caking, the discharged material deviates to one side, or the packing density of the material is poor, resulting in tilting or toppling after the bag is filled. When injecting materials, the weighing sensor senses the weight in the ton bag, and the dynamic load cylinder on the opposite side is used to lift and lower to adjust the materials in the bag. It can also make the bag body impact the conveying roller path through the synchronous up and down movement of the dynamic load cylinder for ramming. The discharging process can ensure that the materials do not come into contact with the outside world, are in a sealed state, reduce the diffusion of dust, and improve the quality and effect of ton bag packaging.

[0032] Refer to Figures 1-10As shown in the figure, a bulk bag packing machine includes: a frame 1 and an installation platform 2 provided on the upper part of the frame 1. A feeding mechanism 3 and a dynamic load mechanism 4 are provided on the installation platform 2. The feeding mechanism 3 is provided with a feeding frame 31, a feeding hopper 32, a feeding component 33 and a discharging hopper 34. An installation opening 21 is provided in the middle of the installation platform 2. The feeding frame 31 is provided at the installation opening 21 of the installation platform 2.

The dynamic load mechanism 4 is provided with a dynamic load frame 41, a dynamic load cylinder 42 and a dynamic load mounting frame 43. The dynamic load frame 41 is provided on the installation platform 2 outside the feeding mechanism 3. A dynamic load hole 22 is provided on the installation platform 2. Four dynamic load cylinders 42 are symmetrically provided. The dynamic load cylinders 42 are fixed on the dynamic load frame 41, and the cylinder rods penetrate through the dynamic load holes 22 and are connected to the dynamic load mounting frame 43 below. A bag clamping mechanism and a bag hanging mechanism are provided on the dynamic load mounting frame. The bag clamping mechanism 5 is provided with a bag clamping cylinder 51, a clamping frame 52, a clamping ring 53 and a clamping cylinder 54. The bag clamping cylinder 51 is fixed in the mounting frame 431. The clamping frame 52 is provided with two pairs of a first clamping frame and a second clamping frame, and a third clamping frame and a fourth clamping frame. One end of the first clamping frame and the second clamping frame is relatively hinged to one side of the bag clamping cylinder 51. One end of the third clamping frame and the fourth clamping frame is relatively hinged to the symmetric side of the bag clamping cylinder 51. The clamping rings 53 are respectively connected to the other ends of the first clamping frame and the third clamping frame, and the second clamping frame and the fourth clamping frame. The clamping cylinders 54 are respectively connected to the middle parts of the first clamping frame and the second clamping frame, and the third clamping frame and the fourth clamping frame. The clamping frame 52 is provided with a clamping frame 521, a connecting rod 522 and a clamping rod 523. The clamping frame 521 is fixed on the side of the bag clamping cylinder 51. The connecting rod 522 is hinged to the clamping frame 521. The clamping rod 523 is in an "L" shape. One end of the "L" shaped clamping rod 523 is obtusely connected to the connecting rod 522, so that the fixed shaft 55 can be installed outside the bag clamping cylinder 51. Fixed shafts 55 are respectively provided between the "L" shaped clamping rods 523 of the first clamping frame and the third clamping frame, and the second clamping frame and the fourth clamping frame.

[0033] The bag clamping mechanism 5 forms a clamp structure through the bag clamping cylinder 51, the clamping frame 52 and the clamping ring 53. Under the action of the clamping cylinder 54, the bag mouth is clamped on the bag clamping cylinder 51, and the clamping and sealing effects are good.

[0034] Through the optimization of the clamping frame 52 and the addition of the design of the fixed shaft 55, the two sides of the clamping frame 52 can be synchronously telescoped, avoiding misalignment during clamping, resulting in incomplete sealing or even damage to the bag mouth.

[0035] The dynamic load mounting bracket 43 is provided with a mounting frame 431 and mounting rods 432. The cylinder rod of the dynamic load cylinder 42 is connected to the four corners of the mounting frame 431. The mounting rods 432 are arranged at the four corners of the mounting frame 431 and are arranged in one-to-one correspondence with the dynamic load cylinders 42. The bag clamping mechanism 5 is arranged inside the mounting frame 431. A telescopic pipe 341 is connected between the blanking hopper 34 and the bag clamping mechanism 5. The bag hanging mechanism 6 is arranged on the mounting rods 432.

[0036] This device is connected to the production line of metal powder materials, such as production equipment for metallic lithium, lithium alloys, lithium ions, and lithium polymers. It is set at the end of the production line for collection. The entire device is integrally connected to the production line and is in a sealed state. The feeding mechanism 3 controls the discharge amount of the material, which falls into the ton bag 9 below. Through the adjustment of the dynamic load mechanism 4, the dynamic load cylinders 42 lift and lower the ton bag 9 simultaneously at intervals to compact the powder inside the ton bag 9 and improve the compactness of the packaging and bagging.

[0037] The bag clamping mechanism 5 seals and connects the bag mouth to prevent the diffusion of dust. The ton bag 9 is hung by the bag hanging mechanism 6 distributed at the four corners, keeping it in a straightened state to avoid problems such as wrinkles and folds in the bag body.

[0038] Furthermore, rubber pads 524 are respectively arranged between the "L"-shaped clamping rods 523 of the first clamping frame and the second clamping frame, and the third clamping frame and the fourth clamping frame. An exhaust filter cartridge 56 is arranged on the side of the bag clamping cylinder 51.

[0039] The rubber pads 524 play a role in clamping and buffering to avoid damaging the bag mouth. The exhaust filter cartridge 56, on the one hand, discharges the internal gas during the discharging process, and on the other hand, discharges the excessive gas of the subsequent added bag blowing mechanism 7.

[0040] Furthermore, the bag hanging mechanism 6 is provided with a mounting plate 61, a sleeve bolt 62, a hook 63, a bag hanging cylinder 64, a baffle 65, and a stop post 66. The upper end of the mounting plate 61 is clamped on both sides of the mounting rod 432 by the sleeve bolt 62. The middle of the hook 63 is rotatably arranged at the lower end of the mounting plate 61 by the sleeve bolt 62. The bag hanging cylinder 64 is fixed on the mounting plate 61 by the sleeve bolt 62 and is hinged to the upper end of the hook 63. The baffle 65 is fixed on the mounting plate 61 opposite to the hook 63 by the sleeve bolt 62. The front end of the baffle 65 is arc-shaped and is pressed against the hook 63. The stop post 66 is in a "U" shape. The "U"-shaped stop post 66 is arranged on the mounting plate 61 between the hook 63 and the baffle 65, and the hook 63 and the baffle 65 are arranged inside the "U"-shaped stop post 66.

[0041] The hanging bag mechanism 6 clamps the mounting plate 61 onto the mounting rod 432 through the sleeve bolts 62. Preferably, two opposite sleeve bolts 62 are respectively arranged on the upper and lower sides of the mounting rod 432 for fixation to ensure the clamping force and the stability of the hanging bag mechanism 6. Before hanging the bag, the hanging bag cylinder 64 contracts, the hook 63 disengages from the baffle 65, the hanging rope is placed into the hook 63 or the baffle 65, the hanging bag cylinder 64 extends forward, the hook 63 abuts against the baffle 65, and the hanging rope is sleeved within the hook 63 and the baffle 65; further, the stop post 66 abuts against the outside of the hanging rope and the hook 63 or the baffle 65, the "U"-shaped stop post 66 abuts against the hook 63 or the baffle 65 from the outside, and in the initial state, the stop post 66 presses the hanging rope onto the hook 63. If the hook 63 undergoes a certain deformation under the action of gravity, the "U"-shaped stop post 66 plays a supporting role to prevent the hook 63 from undergoing greater deformation or damage; if the hanging rope slides towards the baffle 65 under the action of tension, the hanging rope will drive the stop post 66 to rotate, so that the "U"-shaped stop post 66 is located outside the baffle 65, avoiding the problem of excessive deformation or damage of the baffle 65.

[0042] Further, the feeding assembly 33 is provided with a housing 331, a rotating shaft 332, a baffle 333, a rotating rod 334, a linkage rod 335, and a feeding cylinder 336. The housing 331 is arranged on the feeding frame 31, the rotating shaft 332 is arranged on one side of the feeding hopper 32, the rotating shaft 332 is connected to the housing 331 through a bearing seat 337, the feeding port 322 at the lower end of the feeding hopper 32 is arc-shaped, the baffle 333 is correspondingly arranged at the arc-shaped feeding port 322, the baffle 333 is fixedly connected to the rotating shaft 332 through the rotating rod 334, the linkage rod 335 is arranged at one end of the rotating shaft 332, and the feeding cylinder 336 is arranged on the housing 331 and connected to the linkage rod 335.

[0043] The rotating shaft 332 is arranged at the center of the circle of the arc-shaped feeding port 322.

[0044] The feeding assembly 33 rotates to one side, avoiding the rotating shaft 332 passing through the feeding hopper 32, and controlling the size of the discharge port through the rotation angle.

[0045] Further, the feeding cylinder 336 is a two-way cylinder, and the cylinder rods at both ends of the two-way cylinder are respectively hinged to the linkage rod 335 and the housing 331; a sealing plate 323 is arranged on the side of the rotating shaft 332 of the feeding port 322, and the sealing plate 323 is arranged between the baffle 333 and the feeding hopper 32; a limiting plate 338 is arranged on the side of the rotating shaft 332 of the baffle 333 opposite to the rotating shaft 332, and the limiting plate 338 is bent towards the feeding hopper 32 side.

[0046] A two-way cylinder means that the bottoms of two cylinders are fixed together, and the cylinders perform telescopic movements in two opposite directions respectively.

[0047] By controlling the opening of the feeding component 33 through a double-acting cylinder, the required telescopic length for control can be met, avoiding the problem of instability caused by an overly long single cylinder. The sealing plate 323 and the limiting plate 338 play a good role in sealing the feeding hopper 32, preventing material leakage.

[0048] Further, a filling pipe 342 is connected to the lower end of the discharging hopper 34, and the filling pipe 342 is sleeved inside the bag clamping cylinder 51.

[0049] By providing the filling pipe 342, it is possible to get closer to the ton bag 9, avoiding the problem of uneven dispersion of materials in all directions during the discharging process; the filling pipe 342 can be assisted by the dynamic load mechanism 4 to lift the bag clamping mechanism 5 upward, extending the filling pipe 342 as far as possible towards the bottom of the bag body. During the discharging process, the dynamic load mechanism 4 slowly descends to maintain the distance between the lower end of the filling pipe 342 and the upper end of the material, which can also maintain the uniformity of material discharging in the bag body to a certain extent.

[0050] Further, the discharging hopper 34 is provided with a bag blowing mechanism 7. The bag blowing mechanism 7 includes a blower 71, a blowing pipe 72, a connecting hose 73, and a fixing plate 74. The blower 71 is fixed on the installation platform 2. The blowing pipe 72 is arranged inside the discharging hopper 34 and the filling pipe 342. The upper end of the blowing pipe 72 penetrates through the discharging hopper 34 and is connected to the connecting hose 73. The lower end of the blowing pipe 72 is connected to the filling pipe 342 through the fixing plate 74. The connecting hose 73 is connected to the blower 71; an exhaust pipe 75 opposite to the air inlet direction is provided on the side of the connecting hose 73.

[0051] The bag blowing mechanism 7 can well assist in the bag hanging process of the ton bag 9. Through blowing the ton bag 9, the bag body is in a full state, avoiding problems such as wrinkles, and facilitating the height adjustment of the dynamic load mechanism 4, as well as the position adjustment and bag hanging operation of the bag hanging mechanism 6, making the bag body in the best discharging and collecting state; the exhaust pipe 75 is used for exhaust to avoid affecting the feeding. The blower 71 is a medium-pressure blower.

[0052] Although the setting of the bag blowing mechanism 7 can improve the bag hanging and initial setting effects, its blowing pipe 72 is arranged inside the filling pipe 342, affecting the uniformity of discharging, so other mechanisms need to be set for cooperation.

[0053] Further, a conveying roller path 8 is provided below the installation platform 2.

[0054] The conveying roller path 8 facilitates the conveyance of the filled ton bag 9 out of the discharging device.

[0055] During use, first put the opening of the ton bag 9 (usually a ton bag) onto the bag clamping cylinder 51, and then start the clamping cylinder 54 to clamp the bag opening onto the clamping cylinder through the clamping ring 53. Keep the baffle 333 and the plug valve 321 closed, lift the dynamic load mechanism 4, and the ton bag 9 is in a certain suspended state. Then start the blower 71 to blow gas into the ton bag 9 to make the ton bag 9 in a full state. Then hang the hanging ropes of the ton bag 9 onto the bag hanging mechanism 6 respectively, and the position of the bag hanging mechanism 6 can also be adjusted through the sleeve bolt 62 to make the hanging ropes in a certain tensile state to ensure the lifting state of the ton bag 9. Furthermore, adjust the height through the dynamic load mechanism 4 to make the ton bag 9 in a certain suspended state in a full state, and adjust the lifting height of each cylinder in the adjustment state and the compaction state to ensure the effect of subsequent adjustment and ramming operations. After completing the debugging work, close the bag blowing mechanism 7, open the plug valve 321, and start the feeding mechanism 3 to discharge the metal powder. In order to reduce the service life of the dynamic load cylinder 42 and avoid being in a load state all the time, the ton bag 9 is supported on the conveying roller path 8 during the discharging process; when compaction operation is required, the dynamic load mechanism 4 performs lifting and lowering operations. Finally, when weighing is required, the dynamic load mechanism 4 is lifted for real-time weighing to accurately control the discharging amount.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
