Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a rapid packaging machine for automatic feeding of powder materials. Background Art

[0002] Powder casting material is a kind of powder material used in the construction industry, which is generally a mixture of multiple powder materials. In the process of producing powder casting material, the manufacturer generally needs to package the powder material, so a packaging machine is needed. The packaging machine is a device that packs the powder material into a bag and seals the bag.

[0003] Most of the current packaging machines only have the functions of packaging and sealing. When in use, it is necessary to first mix a variety of powder materials in a mixer and then manually carry them to the packaging machine. At the same time, after the packaging machine is bagged, the bagged powder materials need to be weighed. The weighing process generally involves manually carrying the bagged powder materials to a weighing machine for weighing, and then repeatedly adjusting the weight until it meets the standard, and then carrying it to the packaging machine for sealing. Generally speaking, the weight of a bag of powder material is between 25kg and 50kg, and the physical fitness of workers will decrease significantly after multiple handling. This results in the existing packaging machine having a high labor intensity when used because workers are required to carry powder materials multiple times. After working for a long time, the workers' physical fitness will decrease, which will reduce the handling speed, thereby reducing the efficiency of powder material packaging.

[0004] In the utility model with application number: 201821088224.2 and publication number CN208746372U, an automatic collection and packaging integration for metal powder processing is disclosed, including a frame, a collection and conveying mechanism, a fixed frame, a PCL control cabinet, a storage and stirring mechanism, a tensioning mechanism, a first packaging mechanism and a second packaging mechanism. Although it can reduce the number of times workers carry the materials, it still does not have a weighing structure. Workers still need to carry and adjust the weight when weighing, which leads to the problem of reduced powder material packaging efficiency. Utility Model Content

The weighing assembly 202 is arranged at the material outlet 208 at the bottom of the feed box 201 for discharging and weighing.

[0055] The utility model sets a feeding and stirring structure 10, a weighing and packaging structure 20 and a suture structure 30. The feeding and stirring structure 10 is used to mix a variety of powder materials and then convey them to the weighing and packaging structure 20, the weighing and packaging structure 20 is used to load the powder materials into material bags and weigh them, and the suture structure 30 is used to sew the mouth of the material bag.

It solves the problem that when using existing packaging machines, workers need to carry powder materials many times, which leads to high labor intensity. After working for a long time, workers will have reduced physical strength, which reduces the carrying speed and thus reduces the packaging efficiency of powder materials.

[0066] Preferably, the second pulley 115 is inserted into the second track 114 and is slidably connected to the second track 114 .

[0067] When in use, the second pulley 115 and the second track 114 not only play the role of sliding connection, but also play the role of preventing the material from escaping from the loading rack 110.

[0068] In order to make the hopper 111 slide more stably on the loading rack 10 , a third pulley 134 is further provided on the hopper 111 , and the third pulley 134 is arranged in cooperation with the second track 114 .

[0069] Preferably, the loading rack 110 is provided with a driving structure 116 for driving the hopper 111 to slide along the tilting direction of the loading rack 110, and the driving structure 116 includes a driving motor 117, a winch 118, a lifting rope 119, a lifting ring 120, a rotating wheel 121 and a steering pulley block 122. The driving motor 117 is arranged on one side of the loading rack 110, and the winch 118 is arranged on the output shaft of the driving motor 117 and is fixedly connected to the output shaft of the driving motor 117, and is used to reel in the lifting rope 119. The steering pulley block 122 is arranged on the output shaft of the driving motor 117. The upper end of the placement rack 104 is used for steering the lifting rope 119. The lifting ring 120 is arranged on the inner side of the top of the loading rack 110 for fixing the other end of the lifting rope 119. The top of the loading rack 110 is provided with a matching opening 123 for the lifting rope 119 to pass through. One end of the lifting rope 119 is connected to the winch 118, and the other end is turned through the turning pulley set 122, passes through the matching opening 123 at the top of the loading rack 110, and is connected to the lifting ring 120 after being turned through the rotating wheel 121. The rotating wheel 121 is rotatably connected to the hopper 111 through the mounting member 124.

[0070] When in use, the sling rope 119 needs to be wound around the rotating wheel 121 , and the rotating wheel 121 not only plays a role in steering, but also plays a role in enabling the hopper 111 to move as the sling rope 119 is wound and released.

[0071] Preferably, the mounting member 124 includes a pair of mounting blocks 125, a rotating shaft 126 and a wheel frame 127 arranged at the bottom of the hopper 111, the wheel frame 127 is arranged between the two mounting blocks 125, the rotating shaft 126 is arranged between the two mounting blocks 125 and passes through the wheel frame 127, the two ends of the rotating shaft 126 are respectively rotatably connected to the two mounting blocks 125, and the rotating shaft 126 is fixedly connected to the wheel frame 127, the rotating wheel 121 is arranged in the wheel frame 127, and is rotatably connected to the wheel frame 127 through a rotating pin 135.

[0072] When in use, the winch 118 is driven by the driving motor 117, and the winch 118 starts to reel in the sling rope 119. While the sling rope 119 is being reeled in, the rotating wheel 121 is pulled, and an upward external force is applied to the rotating wheel 121, thereby driving the hopper 111 to move upward along the inclined direction of the upper material rack 110, thereby completing the ascent of the hopper 111; when the hopper 111 needs to be lowered, it is only necessary to drive the winch 118 to release the sling rope 119 through the driving motor 117.

[0073] In order to facilitate the discharge of the powder material in the hopper 111, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the inner wall of the lower end of the hopper 111 is inclined inward, and a discharge port 128 is provided at the bottom.

[0074] In order to facilitate the control of material discharge, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a shielding structure 129 for opening or covering the discharge port 128 is provided at the bottom of the hopper 111. The shielding structure 129 includes a shielding plate 130 and a pair of pneumatic telescopic rods 131 for driving the shielding plate 130. A plug-in port 132 for inserting the shielding plate 130 is provided at the bottom of the hopper 111. One end of the shielding plate 130 is inserted into the plug-in port 132 and slidably connected with the bottom of the hopper 111. The other end of the shielding plate 130 is connected to the telescopic end of the pneumatic telescopic rod 131. The pneumatic telescopic rod 131 is arranged on both sides of the bottom of the hopper 111 for driving the shielding plate 130.

[0075] When in use, the shielding plate 130 can be moved by extending and retracting the pneumatic telescopic rod 131 to control the opening or closing of the discharge. At the same time, the speed at which the powder material flows out of the discharge port 128 can be controlled by controlling the extension and retraction distance of the pneumatic telescopic rod 131.

[0076] In order to facilitate the powder material in the hopper 111 to enter the mixer 101, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a feed port 133 is provided on the top of the mixer 101 to cooperate with the discharge port 128 of the hopper 111.

[0077] Preferably, the feed port 133 is connected to the interior of the mixer 101 .

[0078] When in use, after the hopper 111 rises to the upper end of the loading rack 110, the discharge port 128 and the feed port 133 are matched, and the shielding plate 130 is opened to allow the powder material in the hopper 111 to enter the mixer 101 through the discharge port 128 and the feed port 133.

[0079] like Figures 8 to 13 As shown, when the current powder material baler is in use, since there is no weighing structure, the material bags filled with powder materials need to be weighed separately. If the weights are different, workers need to adjust them. Therefore, there are problems such as complicated weighing process and difficult to control the error of manual weight adjustment. In order to solve the above problems, this embodiment is modified on the basis of the above embodiments. The difference from the above embodiments is that the weighing assembly 202 includes a feeding hopper 210, a pneumatic clamping structure 211 and a weighing rod 212. The feeding hopper 210 is arranged below the material outlet 208, and the pneumatic clamping structure 211 is arranged on the feeding hopper 210 for clamping the material bags. One end of the weighing rod 212 is connected to the feeding hopper 210, and the other end is connected to the mounting seat 203.

[0080] A movable connecting pipe 213 is provided on the top of the material discharge funnel 210 , one end of the movable connecting pipe 213 is fixedly connected to the top of the material discharge funnel 210 , and the other end is inserted into the material outlet 208 and movably connected to the material outlet 208 .

[0081] The weighing rod 212 can adopt a rod-shaped single-point weighing sensor among the single-point weighing sensors in the prior art, for example, a single-point weighing sensor of model AZS-100Kg produced by Laumas of Italy.

[0082] When in use, the discharge funnel 210 is set at one end of the weighing rod 212, the discharge funnel 210 is movably connected to the material outlet 208 through the movable connecting tube 213, and then the material bag is clamped on the discharge funnel 210, so that the weighing rod 212 can weigh the weight of the powder material in the material bag. After the powder material in the material bag reaches the set weight, the pneumatic clamping structure 211 is released and the material bag can be removed. This solves the problem that when the current powder material packaging machine is in use, there is no weighing structure, and the material bag filled with powder material needs to be weighed separately. If the weight is different, the worker needs to adjust it, which makes the weighing process complicated and the manual adjustment weight error difficult to control.

[0083] When in use, since the movable connecting tube 213 and the pneumatic clamping structure 211 are both arranged on the discharge funnel 210, and the discharge funnel 210 is arranged on the weighing rod 212, the weight of the movable connecting tube 213, the pneumatic clamping structure 211 and the discharge funnel 210 needs to be subtracted when weighing.

[0084] Generally speaking, the specifications of the material bags used in packaging are mostly between 25kg and 50kg, that is, the weight of the powder material that can be loaded into the material bag is between 25kg and 50kg.

[0085] In order to facilitate the control of the powder material in the storage tank 200 entering the feed box 201, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the switch assembly 209 includes a main body 214, a pair of mounting strips 215, a mounting plate 216, an adjusting screw 217 and a plug-in plate 218.

The feed opening 206 and the feed inlet 207 are respectively connected to the openings 219 at the top and bottom of the main body 214. The mounting strips 215 are respectively arranged on both sides of the main body 214, and the ends extend out of one side of the main body 214. The plate 216 is arranged between the two mounting strips 215, and the two ends are respectively fixedly connected to the end of the mounting strip 215 extending out of one side of the main body 214. The plug-in plate 218 is arranged between the two mounting strips 215. One end of the adjusting screw 217 passes through the mounting plate 216 and is rotatably connected to the plug-in plate 218. The adjusting screw 217 is threadedly connected to the mounting plate 216. The main body 214 is provided with a plug-in slot 220 that is matched with the plug-in plate 218. The plug-in slot 220 is matched with the opening 219. The plug-in plate 218 can be inserted into the plug-in slot 220 to close and open the opening 219 on the main body 214.

[0086] When in use, the adjusting screw 217 can be rotated to drive the plug plate 218 to be inserted into the plug slot 220, thereby closing the opening 219, so as to control the powder material in the storage tank 200 from entering the feed box 201 through the opening 219.

[0087] In order to facilitate the clamping of material bags, this embodiment is modified on the basis of the above embodiment.

[0090] Preferably, both ends of the first pneumatic telescopic rod 227 are rotatably connected to the two first clamping jaws 226 , and both ends of the second pneumatic telescopic rod 229 are rotatably connected to the two second clamping jaws 228 .

[0091] Preferably, the clamping member 225 includes a mounting beam 230 and an arc-shaped clip 231, one end of the mounting beam 230 is fixedly connected to the lower end of one of the first clamping jaws 226 in the first clamping structure 223, and the other end of the mounting beam 230 is fixedly connected to the lower end of one of the second clamping jaws 228 in the second clamping structure 224, and the arc-shaped clip 231 is arranged on the mounting beam 230, and is respectively located on both sides of the bottom of the discharge funnel 210, and is arranged in coordination with the discharge funnel 210.

[0092] When in use, the first clamp 226 is driven by the first pneumatic telescopic rod 227 to bring the two first clamps 226 closer together, and the second clamp 228 is driven by the second pneumatic telescopic rod 229 to bring the two second clamps 228 closer together, so that the arc-shaped clip 231 on the mounting beam 230 fixes the material bag to the bottom of the discharge funnel 210, so that the powder material in the feed box 201 enters the material belt through the material outlet 208, the movable connecting pipe 213 and the discharge funnel 210.

[0093] At the same time, when the weight in the material bag reaches a preset weight, the first clamp 226 is driven by the first pneumatic telescopic rod 227 to move the two first clamps 226 away from each other, and the second clamp 228 is driven by the second pneumatic telescopic rod 229 to move the two second clamps 228 away from each other, thereby making the arc-shaped clip 231 on the mounting beam 230 away from the bottom of the discharge funnel 210 and releasing the material bag.

[0094] In order to facilitate the conveying of the powder material entering the material inlet 207 to the material outlet 208, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that it also includes a feeding component 232. The feeding component 232 is used to convey the powder material entering the material inlet 207 to the material outlet 208. The feeding component 232 includes a conveyor belt 233 arranged in the feeding box 201 and a conveying motor 234 arranged on the outer side wall of the feeding box 201.

[0095] Preferably, the conveyor belt 233 includes a belt body 236, a main rotating shaft 237 and an auxiliary rotating shaft 238, the belt body 236 is sleeved on the outside of the main rotating shaft 237 and the auxiliary rotating shaft 238, the belt body 236 contacts and slides with the inner wall of the feed box 201, the main rotating shaft 237 is arranged on the side of the feed box 201 close to the material outlet 208, the auxiliary rotating shaft 238 is arranged on the side of the feed box 201 close to the material inlet 207, the auxiliary rotating shaft 238 is rotatably connected to the inner wall of the feed box 201, both ends of the main rotating shaft 237 respectively pass through the side walls of the feed box 201 and are rotatably connected to the feed box 201, and one end of the main rotating shaft 237 is connected to the gear reversing box 235.

[0096] When in use, the powder material entering the material inlet 207 falls onto the belt body 236. After the belt body 236 is driven by the main rotating shaft 237 and the conveying motor 234, the powder material on the belt body 236 moves from the side of the material inlet 207 to the side of the material outlet 208, so that the powder material on the belt body 236 can enter the movable connecting tube 213 from the material outlet 208, and then enter the unloading funnel 210.

[0097] In order to facilitate the powder material in the conveying box to no longer enter the movable connecting pipe 213 and the discharge funnel 210 from the material outlet 208 when the powder material in the material bag reaches a preset weight, the present embodiment is modified on the basis of the above embodiment, and the difference from the above embodiment is that a first baffle 239 is provided in the conveying box 201, and the first baffle 239 is arranged above the conveyor belt 233.

The first connecting member 240 is arranged on the outer wall of the conveying box 201, and the other end of the first connecting member 240 is rotatably connected to the output end of the first driving cylinder 241. The first driving cylinder 241 is arranged on the outer wall of the conveying box 201, and the first baffle 239 can be rotated until the lower end of the first baffle 239 contacts the conveyor belt 233, so as to block the powder material on the conveyor belt 233.

The second driving cylinder 244 is arranged on the outer side wall of the feed box 201. The second baffle 242 can be rotated to contact the inner side wall of one side of the feed box 201 to block the material outlet 208.

[0099] When in use, the first connecting member 240 can be driven to rotate by the first driving cylinder 241, thereby driving the first baffle 239 to rotate, thereby blocking the powder material on the conveyor belt 233. At the same time, the second connecting member 243 can be driven to rotate by the second driving cylinder 244, thereby driving the second baffle 242 to rotate, thereby blocking the material outlet 208, thereby preventing the powder material in the feed box 201 from entering the movable connecting pipe 213 and the discharge funnel 210 from the material outlet 208.

[0100] The rotation of the first baffle 239 can be controlled to control the gap between the first baffle 239 and the belt body 236, thereby controlling the amount of powder material on the belt body 236 passing through the first baffle 239, thereby achieving the effect of controlling the conveying speed of the conveyor belt 233 for the powder material.

[0101] The second baffle 242 can be controlled to rotate, thereby controlling the degree of opening of the material outlet 208 and controlling the amount of powder material flowing out of the material outlet 208, thereby achieving the effect of controlling the bagging speed of the powder material.

[0102] Preferably, a controller is also included, and the controller can adopt a PLC controller in the prior art.

[0104] like Figures 14 to 18 As shown, most of the current suture machines are not provided with a height adjustment structure, and there is a problem that they cannot adapt to the suture of the bag openings of material bags of different specifications. In order to solve the above problem, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the suture structure 30 includes a suture machine 300, a transmission component 301 and a lifting component 302. One end of the transmission component 301 is arranged below the feeding funnel 210 in the weighing and packaging structure 20, and the lifting component 302 is arranged at the other end of the transmission component 301. The suture machine 300 is arranged on the lifting component 302 and is located above the transmission component 301.

[0105] The lifting assembly 302 includes a mounting support frame 304, a sliding mounting plate 305 and a mounting frame 306. The mounting support frame 304 is arranged on one side of the transmission assembly 301. The sliding mounting plate 305 is located in front of the side of the mounting support frame 304 close to the transmission assembly 301 and is slidably matched with the mounting support frame 304. The mounting frame 306 is sleeved on the outside of the mounting support frame 304, and one end is connected to the sliding mounting plate 305. A rack 307 is provided on the side of the mounting support frame 304 away from the transmission assembly 301. A rotating gear 308 meshing with the rack 307 is provided on the mounting frame 306. The rotating gear 308 is fixedly arranged on a gear transmission shaft 309, and both ends of the gear transmission shaft 309 are rotatably connected to the mounting frame 306 respectively.

[0106] A gear driving structure 310 is provided on one side of the mounting frame 306, and one end of the gear transmission shaft 309 passes through the mounting frame 306 and is connected to the gear driving structure 310. The gear driving structure 310 can be used to drive the rotating gear 308 to rotate and limit the rotation of the rotating gear 308. The mounting frame 306 and the sliding mounting plate 305 are slidably connected to the mounting support frame 304 through the rotating gear 308 and the rack 307.

[0107] When in use, the material bags packed by the weighing and packing structure 20 can be transported to the suture machine 300 through the transmission component 301, and then the height of the suture machine 300 can be adjusted through the lifting component 302 to adapt to material bags of different specifications;

[0108] The gear driving structure 310 drives the rotating gear 308, thereby causing the rotating gear 308 to move on the rack 307, thereby driving the mounting frame 306 and the sliding mounting plate 305 to move along the direction of the rack 307, thereby enabling the suture machine 300 on the sliding mounting plate 305 to achieve height adjustment;

[0109] The invention solves the problem that the current sewing machine 300 cannot be adapted to sew the bag openings of material bags of different specifications due to the lack of a height adjustment structure when in use.

[0110] The mounting frame 306 and the sliding mounting plate 305 form a sliding connection with the mounting support frame 304 through the cooperation of the rotating gear 308 and the rack 307. During installation, it is necessary to ensure that after the rotating gear 308 and the rack 307 are cooperated, when the rotating gear 308 does not rotate, the mounting frame 306 and the sliding mounting plate 305 are fixed to the mounting support frame 304.

[0111] Preferably, in order to facilitate the adjustment of the upper and lower heights of the suture machine 300 , the rack 307 is vertically arranged on the mounting support frame 304 and fixedly connected to the mounting support frame 304 .

[0112] In order to facilitate the driving of the rotating gear 308 to move on the rack 307 and to fix the rotating gear 308 on the rack 307, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the gear driving structure 310 includes a worm wheel 311, a worm 312, a hand crank handle 313, a rotating mounting seat 314 and a limiting structure 315.

The hand crank handle 313 is set on the worm 312 to drive the worm 312 to rotate, and the limiting structure 315 is matched with the worm 312 to limit the worm 312.

[0113] When in use, the worm 312 is rotated by the hand crank handle 313, so that the worm wheel 311 cooperating with the worm 312 drives the gear transmission shaft 309 to rotate, and then the transmission gear moves on the rack 307, and then drives the installation frame 306, the sliding mounting plate 305 and the sewing machine 300 on the sliding mounting plate 305 to move up and down to achieve height adjustment. The rotation of the worm 312 is limited by the limiting structure 315, and when the worm 312 is not rotated, the height of the sewing machine 300 is fixed.

[0114] In order to facilitate the restriction and release of the restriction on the worm 312, this embodiment is modified on the basis of the above embodiment.

The limiting plate 317 can slide to cooperate with the matching block 318 to limit the rotation of the worm 312.

[0115] When the worm 312 needs to be limited, the limiting plate 317 can be moved to slide the limiting plate 317 to fit with the matching block 318, so that the limiting plate 317 can limit the rotation of the worm 312;

[0116] When the worm 312 needs to be rotated, the limiting plate 317 can be moved to slide to a position where the limiting plate 317 does not cooperate with the matching block 318, thereby allowing the worm 312 to rotate.

[0117] In order to enhance the stability of the limit plate 317, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment lies in that a sliding mounting groove 319 for mounting the limit plate 317 is provided at the bottom of the protective shell 316, and the bottom of the limit plate 317 is installed in the sliding mounting groove 319 and is slidably connected to the sliding mounting groove 319.

[0118] In order to facilitate the movement of the limiting plate 317 , this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a pushing block 320 is provided on the limiting plate 317 , and the pushing block 320 is fixedly connected to the limiting plate 317 .

[0119] In order to facilitate the transfer of material bags packed by the weighing and packaging structure 20 to the suture machine 300 for sealing, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the transmission component 301 includes a transmission belt structure 321 and a transmission motor 322. One end of the transmission belt structure 321 is arranged under the weighing and packaging structure 20, and the other end is arranged in cooperation with the lifting component 302. The transmission motor 322 is arranged on one side of the transmission belt structure 321 for driving the transmission belt structure 321.
