Description

Technical Field

[0001] The present disclosure relates to the technical field of battery production, and in particular to a ton bag feeding device. Background Art

[0002] At present, the feeding process of positive electrode powder is usually carried out manually. The feeding personnel use a crane to transport the ton bag filled with positive electrode powder to the top of the feeding port of the silo, place the ton bag on the pallet position above the feeding port of the silo, open the bag mouth of the ton bag to allow the positive electrode powder to fall naturally into the feeding port of the silo. However, in actual application, it was found that the natural falling speed of the positive electrode powder was too slow, and the feeding personnel needed to manually adjust the bag mouth position of the ton bag according to the bottom situation of the ton bag, resulting in more repetitive work and increased labor intensity for the feeding personnel. Therefore, some manufacturers have made further research and development.

[0003] For example, Chinese patent document CN219601804U discloses a lithium battery powder bulk bag feeding device including a feeding trough, an electric push rod symmetrically connected above the feeding trough, a fixed hook connected to the upper end of the electric push rod, a striking structure symmetrically connected to the upper side wall of the feeding trough, a magnetic suction trough connected around the side wall of the feeding trough, a mesh plate is provided on the side wall of the feeding trough, a plurality of inclined plates are connected to the inner side wall of the feeding trough, a toothed knife is symmetrically connected to the inner wall of the feeding trough, a feeding hopper is provided at the lower end of the feeding trough, a rotating drum is rotatably provided between the feeding trough and the feeding hopper, a screen frame is clamped in the rotating drum, a sealing door matching the screen frame is provided on the side wall of the rotating drum, a clamping slot matching the screen frame is provided on the inner side walls of the rotating drum and the sealing door, and a driving structure is connected to one side of the rotating drum.

[0004] However, the design of the above-mentioned lithium battery powder ton bag feeding device has the following problems:

[0005] Although the above-mentioned lithium battery powder ton bag feeding device can lift the ton bag by a fixed hook and accelerate the falling of the positive electrode powder in the ton bag by hitting it with a striking structure, due to the limited direction and force of the hitting structure, it can only act on a part of the ton bag, so that the positive electrode powder will still adhere to the area of ​​the ton bag away from the hitting structure, resulting in residual waste of the positive electrode powder.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1) Because the bag-shaking chamber of the swinging rotating frame is connected to the ton bag storage chamber through the bag-feeding port, when the ton bag is placed in the ton bag storage chamber, the bottom of the ton bag can be extended into the bag-shaking chamber.

The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figure 1 and Figure 2As shown, a ton bag feeding device 10 of an embodiment includes a load-bearing frame 100, at least two lifting components 200, a swinging rotating frame 300 and a plurality of bag clamping claws 400; the load-bearing frame 100 is sequentially formed with a bag feeding port 1110, a ton bag accommodating cavity 1310 and a discharge port 1221 which are connected from top to bottom; at least two lifting components 200 are symmetrically arranged on the peripheral side of the load-bearing frame 100, and the hook 210 of the lifting component 200 is located above the bag feeding port 1110; the swinging rotating frame 30 0 is rotatably connected to the load-bearing frame 100 and corresponds to the bag throwing port 1110; a bag shaking cavity 321 is formed in the swing rotating frame 300, and the bag shaking cavity 321 is connected to the ton bag accommodating cavity 1310 through the bag throwing port 1110; a plurality of bag clamping claws 400 are arranged at intervals on the cavity wall of the bag shaking cavity 321, and the cavity wall of the bag shaking cavity 321 forms a hanging opening 322 between two adjacent bag clamping claws 400, and the hook 210 of each lifting component 200 is arranged opposite to a hanging opening 322.

[0034] It can be understood that because the bag shaking chamber 321 of the swinging and rotating frame 300 is connected to the ton bag accommodating chamber 1310 through the bag throwing port 1110, when the ton bag is placed in the ton bag accommodating chamber 1310, the bottom end of the ton bag can be extended into the bag shaking chamber 321, and a plurality of bag clamping claws 400 are arranged at intervals on the wall of the bag shaking chamber 321, so that the side corners of the top end of the ton bag can be clamped by the bag clamping claws 400, and because the hook 210 of each lifting component 200 is opposite to the hanging opening 322 formed between two adjacent bag clamping claws 400, the hanging belt at the top end of the ton bag can pass through the hanging opening 322 and be hung on the hook 210 of the lifting component 200, so that the bottom end of the ton bag is lifted and suspended above the discharge port 1221. Because the swinging and rotating frame 300 is rotatably connected to the load-bearing frame 100, when it is necessary to feed materials to the discharge port 1221, the bottom end of the ton bag can be cut open to allow the positive electrode powder in the ton bag to fall toward the discharge port 1221 and synchronously rotate the swinging and rotating frame 300. The swinging and rotating frame 300 can drive the ton bag to shake in the bag shaking chamber 321 through the bag clamping claws 400, thereby ultimately increasing the unloading speed of the ton bag.

[0035] It can be understood that compared with the lithium battery powder ton bag feeding device in the prior art, the ton bag feeding device 10 of the present embodiment clamps the side angle of the top of the ton bag through the bag clamping claws 400 in the bag shaking cavity 321, so that when the swing rotating frame 300 rotates relative to the load-bearing frame 100, the ton bag in the bag shaking cavity 321 is synchronously driven to twist. During the twisting process, vertical wrinkles will be generated on the outer surface of the ton bag. The vertical wrinkles can transmit the vibration to a position away from the bag clamping claws 400, thereby producing a shaking effect on the ton bag as a whole, thereby enabling the positive electrode powder adsorbed in various areas of the ton bag to fall faster, thereby reducing the residual positive electrode powder.

[0036] Combination Figure 1 and Figure 3As shown, in one embodiment, the swinging rotating frame 300 includes a swinging ring 310 and a plurality of connecting plates 320; the swinging ring 310 is coaxially arranged above the bag throwing port 1110; a plurality of connecting plates 320 are vertically arranged between the swinging ring 310 and the bag throwing port 1110, and are distributed around to form a bag shaking cavity 321; the upper end of each connecting plate 320 is fixedly connected to the swinging ring 310, and the lower end of each connecting plate 320 is slidably arranged on the end surface of the bag throwing port 1110; the plurality of connecting plates 320 are arranged at intervals to form a hanging opening 322; each bag clamping claw 400 is arranged on a connecting plate 320. It can be understood that by vertically arranging a plurality of connecting plates 320 between the swing ring 310 and the bag throwing port 1110, and by fixing the upper end of each connecting plate 320 to the swing ring 310, the swing ring 310 can be supported by each connecting plate 320 to form a bag shaking cavity 321. At the same time, since the lower end of each connecting plate 320 is slidably arranged on the end surface of the bag throwing port 1110, the swing ring 310 can rotate with the sliding of each connecting plate 320. When the side angle of the top end of the bag of the ton bag is clamped by the bag clamping claw 400 on the connecting plate 320, the connecting plate 320 can synchronously shake the ton bag, thereby ultimately improving the unloading speed of the ton bag.

[0037] Combination Figure 1 and Figure 3 As shown, in the present embodiment, the load-bearing frame 100 includes a sliding guide ring 110, a pressure-bearing base 120 and a plurality of support rods 130; a discharge port 1221 is opened on the pressure-bearing base 120, and the sliding guide ring 110 is coaxially arranged above the discharge port 1221; a plurality of support rods 130 are arranged between the sliding guide ring 110 and the pressure-bearing base 120, and are distributed around to form a ton bag accommodating chamber 1310; the two ends of each support rod 130 are respectively connected to the periphery of the pressure-bearing base 120 and the sliding guide ring 110; the inner ring of the sliding guide ring 110 forms a bag delivery port 1110, and the sliding guide ring 110 forms an arc-shaped guide rail 1120 between two adjacent support rods 130; a sliding sleeve 1130 is provided on each arc-shaped guide rail 1120, and the lower end of each connecting plate 320 is correspondingly connected to a sliding sleeve 1130. It can be understood that by arranging a plurality of support rods 130 between the sliding guide ring 110 and the pressure base 120, and by connecting the two ends of each support rod 130 to the periphery of the pressure base 120 and the sliding guide ring 110 respectively, the sliding guide ring 110 can be supported by each support rod 130 to form a ton bag accommodating chamber 1310. Since the sliding guide ring 110 forms an arc-shaped guide rail 1120 between two adjacent support rods 130, and by connecting the lower end of each connecting plate 320 to a corresponding sliding sleeve 1130 on the arc-shaped guide rail 1120, each connecting plate 320 can be more smoothly rotated along the arc-shaped guide rail 1120 relative to the bag delivery port 1110.

[0038] Combination Figure 1As shown, in one of the embodiments, a swing drive assembly 500 is also provided on the load-bearing frame 100; the swing drive assembly 500 includes a bracket 510, a rotation driver 520 and a driving gear 530, the bracket 510 is vertically arranged on one side of the swing rotating frame 300, and the bottom end of the bracket 510 is fixedly connected to the sliding guide ring 110; the top end of the bracket 510 is close to the swing ring 310, and the rotation driver 520 is installed; a driven rack 311 is convexly provided on the swing ring 310; the driving gear 530 is arranged on the power output shaft of the rotation driver 520, and meshes with the driven rack 311. It can be understood that by vertically arranging the bracket 510 on one side of the swinging rotating frame 300, the top of the bracket 510 is close to the swinging ring 310, and by installing the rotating driver 520 on the top of the bracket 510, the driving gear 530 on the power output shaft of the rotating driver 520 can engage with the driven rack 311 protruding from the swinging ring 310. Since the bottom end of the bracket 510 is fixedly connected to the sliding guide ring 110, the swinging ring 310 can be driven to rotate relative to the sliding guide ring 110 by the rotating driver 520, that is, the swinging rotating frame 300 can swing relative to the load-bearing frame 100 to realize automatic shaking of the ton bag.

[0039] Combination Figure 2 and Figure 3 In this embodiment, there are two swing drive assemblies 500, and the two swing drive assemblies 500 are respectively arranged on opposite sides of the swing rotating frame 300, and the driving gears 530 of the two swing drive assemblies 500 rotate in opposite directions. It can be understood that by arranging a swing drive assembly 500 on opposite sides of the swing rotating frame 300, since the driving gears 530 of the two swing drive assemblies 500 rotate in opposite directions, the swing rotating frame 300 can be driven to rotate forwardly by one swing drive assembly 500, and the swing rotating frame 300 can be driven to rotate reversely by the other swing drive assembly 500, so as to swing the swing rotating frame 300 back and forth, so that the ton bag in the shaking bag cavity 321 of the swing rotating frame 300 can be twisted back and forth to further increase the unloading speed. Specifically, the driving gear 530 of one swing drive assembly 500 rotates clockwise, and the driving gear 530 of the other swing drive assembly 500 rotates counterclockwise.

[0040] Combination Figure 3 and Figure 4As shown, further, there are two driven racks 311, each driven rack 311 is close to a driving gear 530; both sides of the wheel surface of each driving gear 530 are divided into an arc portion 5310 and a tooth portion 5320; in the two swing drive assemblies 500, the tooth portion 5320 of one driving gear 530 is meshed with the corresponding driven rack 311, and the tooth portion 5320 of the other driving gear 530 is away from the corresponding driven rack 311, so as to alternately drive the swing rotating frame 300 to reciprocate. It can be understood that by arranging each driven rack 311 correspondingly close to a driving gear 530, the driving gears 530 of the two swing drive assemblies 500 can be respectively meshed with the corresponding driven racks 311, and because the two sides of the wheel surface of each driving gear 530 are divided into an arc portion 5310 and a tooth portion 5320, when the tooth portion 5320 of one driving gear 530 is meshed with the corresponding driven rack 311, the tooth portion 5320 of the other driving gear 530 will deviate from the corresponding driven rack 311, thereby avoiding interference caused by the two driving gears 530 driving the swing rotating frame 300 at the same time. Specifically, in the driving gears 530 of the two swing drive assemblies 500, when the tooth portion 5320 of the first driving gear 530 is engaged with the corresponding driven rack 311, the arc portion 5310 of the second driving gear 530 will be opposite to the corresponding driven rack 311, and will not hinder the first driving gear 530 from driving the swing rotating frame 300 to rotate forward. After the swing rotating frame 300 rotates forward by a certain angle, the tooth portion 5320 of the second driving gear 530 will just be able to engage with the corresponding driven rack 311, and the arc portion 5310 of the first driving gear 530 will be opposite to the corresponding driven rack 311, and will not hinder the second driving gear 530 from driving the swing rotating frame 300 to rotate in the opposite direction and reset. Finally, the tooth portions 5320 of the two driving gears 530 can alternately drive the swing rotating frame 300 to make the ton bag in the bag shaking cavity 321 twist back and forth more quickly and smoothly.

[0041] Combination Figure 1 and Figure 3As shown, in one embodiment, the pressure base 120 includes a supporting upper ring 1210, a supporting lower ring 1220, a plurality of supporting connecting rods 1230 and a plurality of supporting legs 1240; the supporting lower ring 1220 is coaxially arranged in the supporting upper ring 1210, and the inner ring of the supporting lower ring 1220 forms a discharge port 1221; a plurality of supporting connecting rods 1230 are arranged between the supporting upper ring 1210 and the supporting lower ring 1220, and the two ends of each supporting connecting rod 1230 are respectively connected to the supporting upper ring 1210 and the supporting lower ring 1220; each supporting rod 130 is connected to the supporting upper ring 1210; a plurality of supporting legs 1240 are arranged on the supporting upper ring 1210 at intervals, and extend to one end away from the supporting rod 130. It can be understood that by coaxially arranging the lower support ring 1220 in the upper support ring 1210, the two ends of each support link 1230 can be connected to the upper support ring 1210 and the lower support ring 1220, respectively, so that a firm pressure-bearing structure can be formed between the upper support ring 1210 and the lower support ring 1220, thereby being able to bear heavier ton bags. At the same time, by arranging multiple legs 1240 at intervals on the upper support ring 1210, the weight can be dispersed, and by extending the multiple legs 1240 to the end away from the support rod 130, the entire pressure-bearing base 120 can be stably supported.

[0042] Combination Figure 1 and Figure 2 As shown, in one embodiment, the lifting assembly 200 includes a hook 210, a pillar 220 and a lifting drive 230, the lifting drive 230 is vertically arranged on the pillar 220, the telescopic rod 2310 of the lifting drive 230 is close to the swing rotating frame 300, and the hook 210 is arranged at the top of the telescopic rod 2310 of the lifting drive 230. It can be understood that by vertically arranging the lifting drive 230 on the pillar 220, the telescopic rod 2310 of the lifting drive 230 can be close to the swing rotating frame 300, and by arranging the hook 210 at the top of the telescopic rod 2310 of the lifting drive 230, the suspension belt at the top of the bag of the ton bag can be hung on the hook 210, and finally the entire ton bag is automatically and quickly lifted or lowered by the telescopic rod 2310.

[0043] Combination Figure 1As shown, in this embodiment, a weighing unit 2210 is provided on the pillar 220, the lifting driver 230 is pressed against and fixedly arranged on the weighing unit 2210, and a control unit 5110 is provided on the bracket 510, and the control unit 5110 is electrically connected to the rotating driver 520 and the weighing unit 2210 respectively. It can be understood that by fixing the lifting driver 230 on the weighing unit 2210, when the lifting driver 230 lifts the ton bag, it can press against the weighing unit 2210, so that the weighing unit 2210 obtains the real-time weight of the ton bag. Since the control unit 5110 is provided on the bracket 510 and is electrically connected to the rotating driver 520 and the weighing unit 2210 respectively, the weighing unit 2210 can feed back the real-time weight of the ton bag to the control unit 5110, and the control unit 5110 can timely adjust the rotation speed of the rotating driver 520 according to the real-time weight of the ton bag, so that the swinging rotating frame 300 can automatically adjust the swinging and shaking degree according to the unloading situation of the ton bag in real time. Specifically, the weighing unit 2210 may adopt a weighing sensor, and the control unit 5110 may adopt a PLC (Programmable Logic Controller) or a single-chip microcomputer, which is not limited here.

[0044] It should be particularly noted that the method by which the weighing unit 2210 obtains the real-time weight of the ton bag, the method by which the control unit 5110 receives feedback from the weighing unit 2210, and the method by which the control unit 5110 adjusts the rotational speed of the rotary driver 520 are all prior arts and are not within the scope of protection of the present disclosure. The present disclosure only protects the positional relationship and connection relationship between the various components of the ton bag feeding device 10.

[0045] In one embodiment, the electrical connection may be in various forms such as wired connection, wireless connection, etc. It is understood that the wired connection may be a wire connection or a circuit board connection, etc., and the wireless connection may be a Bluetooth connection or a WIFI (Wireless Fidelity) connection, etc. The specific connection method is not limited, and those skilled in the art may also adjust it as needed.

[0046] Combination Figure 1 and Figure 2As shown, in one embodiment, a mounting opening 323 is opened on the connecting plate 320, and the bag clamping claw 400 is arranged in the mounting opening 323; the bag clamping claw 400 includes a first claw arm 410 and a second claw arm 420 which are cross-rotatably connected by a rotating shaft 430, and the two ends of the rotating shaft 430 are respectively connected to the inner wall of the mounting opening 323, and the clamping end of the first claw arm 410 and the clamping end of the second claw arm 420 extend into the bag shaking cavity 321. It can be understood that by arranging the bag clamping claw 400 in the installation opening 323, because the first claw arm 410 of the bag clamping claw 400 and the second claw arm 420 of the bag clamping claw 400 are cross-rotatingly connected through the rotating shaft 430, and the two ends of the rotating shaft 430 are respectively connected to the inner wall of the installation opening 323, the bag clamping claw 400 is firmly installed on the connecting plate 320, and by extending the clamping end of the first claw arm 410 and the clamping end of the second claw arm 420 into the bag shaking cavity 321, when the first claw arm 410 and the second claw arm 420 rotate around the rotating shaft 430, the clamping end of the first claw arm 410 and the clamping end of the second claw arm 420 can approach and clamp the side corners of the top end of the bag of the ton bag, and then the ton bag can be clamped and twisted by the bag clamping claw 400.

[0047] In one embodiment, in order to facilitate better understanding, the use process of the ton bag feeding device 10 of the above embodiment is now described as follows:

[0048] First, manually put the ton bag into the ton bag accommodating cavity 1310 of the load-bearing frame 100, then make the hanging belt at the top of the ton bag pass through the hanging port 322 and hang on the hook 210 of the telescopic rod 2310, then start the lifting driver 230 of the lifting assembly 200, and the telescopic rod 2310 of the lifting driver 230 lifts the entire ton bag, so that the top of the ton bag is located in the bag shaking cavity 321 and the bottom of the ton bag is suspended above the discharge port 1221, and the bottom of the ton bag is cut, and the positive electrode powder in the ton bag falls freely to the discharge port 1221 due to gravity. When the weight of the ton bag is visually reduced by 50%, the bag clamping claw 400 is manually used to clamp the side angle of the top of the ton bag. After the weighing unit 2210 senses that the weight of the ton bag is reduced by 70%, the weighing unit 2210 sends a signal to the control unit 5110. The control unit 5110 controls the rotation driver 520 to rotate. The rotation driver 520 drives the swing ring 310 of the swing rotating frame 300 through the driving gear 530. The swing rotating frame 300 rotates synchronously to make the ton bag twist in the bag shaking chamber 321, and finally accelerates the unloading of the bottom end of the ton bag.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] 1) Because the bag shaking chamber 321 of the swinging and rotating frame 300 is connected to the ton bag accommodating chamber 1310 through the bag throwing port 1110, when the ton bag is placed in the ton bag accommodating chamber 1310, the bottom end of the ton bag can be extended into the bag shaking chamber 321, and a plurality of bag clamping claws 400 are arranged at intervals on the wall of the bag shaking chamber 321, so that the side corners of the top end of the ton bag can be clamped by the bag clamping claws 400, and because the hook 210 of each lifting component 200 is opposite to the hanging opening 322 formed between two adjacent bag clamping claws 400, the hanging belt at the top end of the ton bag can pass through the hanging opening 322 and be hung on the hook 210 of the lifting component 200, so that the bottom end of the ton bag is lifted and suspended above the discharge port 1221. Because the swinging and rotating frame 300 is rotatably connected to the load-bearing frame 100, when it is necessary to feed materials to the discharge port 1221, the bottom end of the ton bag can be cut open to allow the positive electrode powder in the ton bag to fall toward the discharge port 1221 and synchronously rotate the swinging and rotating frame 300. The swinging and rotating frame 300 can drive the ton bag to shake in the bag shaking chamber 321 through the bag clamping claws 400, thereby ultimately increasing the unloading speed of the ton bag.

[0051] 2) Compared with the lithium battery powder ton bag feeding device in the prior art, the ton bag feeding device 10 disclosed in the present invention clamps the side angle of the top of the ton bag through the bag clamping claws 400 in the bag shaking cavity 321, so that when the swing rotating frame 300 rotates relative to the load-bearing frame 100, the ton bag in the bag shaking cavity 321 is synchronously driven to twist. During the twisting process, vertical wrinkles will be generated on the outer surface of the ton bag. The vertical wrinkles can transmit the vibration to a position away from the bag clamping claws 400, thereby producing a shaking effect on the ton bag as a whole, thereby enabling the positive electrode powder adsorbed in various areas of the ton bag to fall faster, reducing the residual positive electrode powder.

[0052] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
