Description

Technical Field

[0001] The invention relates to the technical field of packaging bag tipping, and in particular to a packaging bag tipping device for particle packaging. Background Art

[0002] The bag tipping device is a professional mechanical device used in industrial production or packaging processing. It is mainly used to flip and tip the bag filled with materials to achieve efficient material unloading. The equipment usually has a stable mechanical structure and power drive system, which can accurately control the tipping angle, speed and strength of the bag. Through the automated process, the unloading efficiency can be greatly improved and the intensity and errors of manual operation can be reduced.

[0003] The functions of the current packaging bag tipping equipment on the market are relatively simple. They can only complete the tipping operation of the packaging bag, and other devices are needed for unloading. This increases the operation steps, reduces work efficiency, and is extremely inconvenient to use. Moreover, during the tipping process, the packaging bag will be subjected to a large impact force, and it is easy to be damaged over a large area, such as tearing. This not only affects the reuse of the packaging bag, but if it is damaged during unloading, it will also cause material leakage and pollute the environment, while increasing the company's material loss and cleaning costs. For this reason, this application proposes a device that can unload the packaging bag without tipping it over, while greatly reducing the damage to the packaging bag. Summary of the invention

[0010] Preferably, a hydraulic device is installed below the mounting plate to drive the mounting plate to rise and fall.

[0011] Preferably, the driving mechanism includes two inflation devices which are fixedly mounted on the upper surface of the mounting plate and are symmetrically arranged, a driven gear is rotatably mounted on the top of the inflation device, a rotating motor which is fixedly mounted on the upper surface of the mounting plate is provided between the two inflation devices, the output end of the rotating motor is key-connected with a main gear, and the main gear is meshingly connected with the driven gear.

[0012] Preferably, a fixing rod is fixedly mounted on the top end of the driven gear, a moving rod is detachably mounted on the top end of the fixing rod, and the top end of the moving rod is fixedly connected to the pulling head.

[0013] Preferably, the input end of the inflation device is connected to an air inlet pipe, and the end of the air inlet pipe away from the inflation device is connected to an external high-pressure gas supply device.

The uniform reciprocating motion driven by the bottom hydraulic device combined with the thread groove design forms a dynamic discharge channel, avoiding the problem of local pressure concentration that is prone to occur in traditional dumping methods. The inflation device maintains the stability of the packaging bag shape through continuous air pressure injection, and optimizes the material fluidity through the internal gas gap, doubly ensuring the operational reliability of the discharge system.

[0016] 2. The fine puncture of the pull-out head and the gas injection of the graphite head in this application work together to control the bottom damage to a very small range; the winding roller and the friction roller cooperate to realize the orderly winding of the empty bag to avoid secondary damage. The arc-shaped protrusion staged support design disperses the bottom pressure at the critical stage of the initial discharge to prevent accidental rupture. After the complete operation process, the packaging bag maintains structural integrity and can be reused after simple treatment, which greatly reduces the consumption of disposable packaging materials and meets the needs of circular economic development.

[0017] In summary, in this application, the pull-out head and the rotating motor are linked to accurately puncture the bottom of the packaging bag, and the friction roller is used to disperse the gravity impact of the material. The bottom hydraulic pressure is combined with the threaded groove to form a dynamic discharge channel to avoid local pressure concentration. The inflation device ensures the shape of the packaging bag and the fluidity of the material. At the same time, the pull-out head puncture and the graphite head gas injection work together to control the damage range, and the various components cooperate to realize the empty bag winding, reduce the consumption of packaging materials, and meet the needs of the circular economy.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figures 1 to 6 A packaging bag overturning device for particle packaging comprises a fixed outer frame 1, a rotating shaft 26 is rotatably installed on the top of the fixed outer frame 1, the rotating shaft 26 is driven by a side motor 28 fixedly installed on the fixed outer frame 1, a rotating inner frame 2 located inside the fixed outer frame 1 is fixedly installed on the rotating shaft 26, hydraulic rods 24 are fixedly installed on both sides of the rotating inner frame 2 and between the fixed outer frame 1, and a fixed plate 9 is fixedly installed on the inner side of the rotating inner frame 2, so that the fixed plate 9 is driven to rotate by the cooperation of the fixed outer frame 1, the rotating inner frame 2, the rotating shaft 26, the hydraulic rod 24 and the side motor 28.

[0027] A placing plate 5 is integrally formed on the inner bottom wall of the fixed plate 9. The placing plate 5 is funnel-shaped, and a packaging bag 12 is placed on the upper end surface of the placing plate 5. Two symmetrically arranged friction rollers 7 are rotatably installed at the middle position of the inner wall on the rear side of the fixed plate 9. The two friction rollers 7 are respectively located on each side of the packaging bag 12 and are in rotational contact with the surface of the packaging bag 12. The friction rollers 7 are driven by a driving device fixedly installed on the rear side wall of the fixed plate 9, and the two friction rollers 7 rotate in opposite directions. When the friction rollers 7 rotate, they can assist the packaging bag 12 in the lifting process to avoid the packaging bag 12 from being broken when it is rolled up due to the excessive weight of the material in the packaging bag 12 in the initial state.

[0028] Two symmetrically arranged back plates 8 are fixedly installed on the upper inner wall of the rear side of the fixed plate 9, and a winding roller 10 is rotatably installed between the two back plates 8. The winding roller 10 is driven by a driving motor 11 fixedly installed on any one of the back plates 8. The top end of the packaging bag 12 is fixed to the winding roller 10, so that the packaging bag 12 can be rolled up by driving the winding roller 10 when the driving motor 11 is running.

[0029] A mounting plate 3 is arranged below the placement plate 5, and a hydraulic press 4 for driving the mounting plate 3 to be lifted and lowered is arranged below the mounting plate 3. Two symmetrically arranged inflatable devices 17 are fixedly installed on the upper end surface of the mounting plate 3, and a driven gear 15 is rotatably installed on the top of the inflatable device 17. A rotating motor 13 fixedly installed on the upper end surface of the mounting plate 3 is arranged between the two inflatable devices 17. The output end of the rotating motor 13 is keyed to a main gear 14, and the main gear 14 is meshed with the driven gear 15, so that the two driven gears 15 can be driven to rotate by the main gear 14 when the rotating motor 13 is running. A fixing rod 18 is fixedly installed on the top of the driven gear 15, and a moving rod 19 is detachably installed on the top of the fixing rod 18. A pulling head 21 designed in a conical shape is fixedly connected to the top of the moving rod 19, and a threaded groove 22 is provided on the surface of the pulling head 21, and a graphite head 23 is detachably installed on the top of the pulling head 21, and a through groove for the graphite head 23 to pass through is provided on the placement plate 5.

[0030] The rotation of the driven gear 15 can drive the fixed rod 18, the movable rod 19, the pull-out head 21 and the graphite head 23 to rotate synchronously. The rotation of the pull-out head 21 and the threaded groove 22 on its upper surface can efficiently pour out the raw materials in the packaging bag 12.

[0031] The input end of the inflation device 17 is connected to an air inlet pipe 16, and one end of the air inlet pipe 16 away from the inflation device 17 is connected to an external high-pressure gas supply device. An air inlet chamber 20 is commonly provided inside the fixed rod 18, the movable rod 19 and the pulling head 21. The output end of the inflation device 17 is connected to the lower end of the air inlet chamber 20 after rotating through the driven gear 15. The upper end of the air inlet chamber 20 contacts the lower end of the graphite head 23. Since the graphite head 23 is made of graphite material and there are gaps inside the graphite, the high-pressure gas entering the air inlet chamber 20 can be ejected through the gaps inside the graphite head 23, so that the high-pressure gas enters the packaging bag 12. On the one hand, the high-pressure gas entering the packaging bag 12 can increase the gaps between the raw materials in the packaging bag 12, making it easier for the raw materials to flow out; on the other hand, the packaging bag 12 can be maintained in a bulging state to avoid large deformation of the packaging, ensure smooth bottom discharge, and at the same time make the winding process of the upper packaging bag 12 more stable without distortion.

[0032] An arc-shaped protrusion 6 is provided at the top of the placement plate 5, and the arc-shaped protrusion 6 is located between the two pull-out heads 21, providing a support area between the two discharge ports at the bottom of the packaging bag 12 to prevent the bottom of the packaging bag 12 from rupturing due to excessive initial bottom pressure, thereby increasing the difficulty of subsequent recycling of the packaging bag 12.

[0033] A transverse sliding groove is provided above the inner wall at the rear side of the fixing plate 9 , an electric slider is installed inside the sliding groove, and an electric blade 27 is fixedly installed on the electric slider toward the packaging bag 12 , and the electric blade 27 is used to cut the upper position of the packaging bag 12 .

[0034] When the present invention is used, during the material handling process, the packaging bag 12 to be overturned is first accurately placed on the placement plate 5 with the help of a lifting device. When the packaging bag 12 is placed vertically, there will be a section of spare part at its upper end, and the winding roller 10 is used to fix this section of spare packaging bag 12. At the same time, both sides of the packaging bag 12 are clamped by the friction roller 7, and the friction roller 7 can rotate, playing an auxiliary role in the lifting process of the packaging bag 12, so as to avoid the packaging bag 12 from being broken when being rolled up due to the excessive weight of the material in the packaging bag 12 in the initial state.

[0035] When the packaging bag 12 is placed on the placement plate 5, the pull-out head 21 at the bottom of the placement plate 5 quickly pierces the bottom of the packaging bag 12. In this process, once the packaging bag 12 contacts the pull-out head 21, the rotating motor 13 is immediately started, and the driven gear 15 is driven to rotate through the main gear 14, thereby driving the pull-out head 21 to rotate synchronously, helping it to pierce the packaging bag 12 more smoothly. At the same time, the air inlet pipe 16 starts to fill the inflation device 17 with high-pressure gas.

[0036] After the pull-out head 21 successfully enters the packaging bag 12, the drive motor 11 is started, and the friction roller 7 causes the packaging bag 12 to rise slowly. The rotation of the friction roller 7 on the side will apply an extrusion force to the middle of the raw materials inside the packaging bag 12 to ensure that the raw materials can be poured out more smoothly. At the same time, the hydraulic press 4 at the bottom is started to allow the mounting plate 3 to reciprocate up and down at a uniform speed. The pull-out head 21 performs reciprocating extraction and insertion actions at the bottom of the packaging bag 12. Combined with the rotation of the pull-out head 21 and the threaded groove 22 on its upper surface, the raw materials inside the packaging bag 12 can be poured out efficiently. In this way, the raw materials can not only flow out of the packaging bag 12 along the threaded groove 22, but also the rotation and up and down movement of the pull-out head 21 can effectively prevent the blockage of the raw materials due to excessive pressure, and always keep the discharge port of the packaging bag 12 unobstructed, greatly improving the discharge efficiency.

[0037] The inflator 17 fills the air inlet chamber 20 with high-pressure gas, which is then ejected from the graphite head 23 and filled into the packaging bag 12. The gas filled in has multiple functions: on the one hand, it can increase the gap between the raw materials in the packaging bag 12, making it easier for the raw materials to flow out; on the other hand, it can keep the packaging bag 12 in a bulging state, prevent the packaging bag 12 from undergoing a large deformation, ensure smooth discharge from the bottom, and make the winding process of the upper packaging bag 12 smoother without distortion. In addition, as the upper part of the packaging bag 12 is slowly wound up, the space above the packaging bag 12 is compressed, squeezing out the internal air, providing a stable and suitable pressure for the discharge port, and ensuring discharge efficiency.

[0038] In the initial stage of discharging, the arc-shaped protrusion 6 in the middle is located between the two pull-out heads 21, providing a support area between the two discharging ports at the bottom of the packaging bag 12 to prevent the bottom of the packaging bag 12 from breaking due to excessive initial bottom pressure, which increases the difficulty of subsequent packaging bag recycling. As the raw materials in the packaging bag 12 are continuously poured out, the packaging bag 12 is slowly lifted up and eventually leaves the arc-shaped protrusion 6. At this time, the pressure at the bottom of the packaging bag 12 is reduced due to the reduction of internal raw materials, and after being completely lifted up, the shape of the bottom of the packaging bag 12 changes from a concave middle to a downward protruding arc, further optimizing the conditions for pouring out the raw materials.

[0039] Finally, all the raw materials slide down from the placement plate 5 and fall into the collection frames placed on both sides to complete the collection. At this time, all the raw materials in the packaging bag 12 are poured out, the bottom is minimally damaged, there is no large-scale rupture, and it can be rolled up on the winding roller 10 intactly. After being removed, it can be reused after simple treatment.

[0040] After the internal raw materials are poured out, a certain amount of raw materials may still remain on the fixed plate 9 and the placement plate 5. At this time, the side motor 28 can be started to drive the rotating inner frame 2 to rotate, and the fixed plate 9 can be lifted in conjunction with the rotating shaft 26 and the hydraulic rods 24 on both sides. The raw materials remaining on the fixed plate 9 and the placement plate 5 are poured out from the rear discharge port 25 on the back. This is more convenient and does not require workers to clean, reducing work intensity.

[0041] When dealing with lighter raw materials, you can also choose to remove the pulling head 21 from the fixed rod 18, directly start the rotating inner frame 2 and the hydraulic rod 24, use the friction rollers 7 on both sides, the fixed plate 9 on the top and the winding roller 10 in the middle as fixed points, start the electric blade 27, cut the top of the packaging bag 12, and then directly pour the raw materials in the packaging bag 12 through the above steps.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
