DETAILED DESCRIPTION

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] like Figures 1 to 6 As shown, in order to solve the above problems, the present embodiment discloses a powder material packaging machine with a weighing function, including a storage tank body 200, a feeding box 201, a weighing assembly 202 and a mounting seat 203. The top of the storage tank body 200 is provided with a loading port 205 connected to a mixer discharge pipe 204, and the bottom of the storage tank body 200 is provided with a discharge port 206. The top side of the feeding box 201 is provided with a material inlet 207, and the bottom side is provided with a material outlet 208. The mounting seat 203 is arranged on the other side of the bottom of the feeding box 201, and the discharge port 206 is connected to the material inlet 207 through a switch assembly 209.

[0032] 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. The pneumatic clamping structure 211 is arranged on the feeding hopper 210 for clamping the material bag.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] Generally speaking, the specifications of the material bags used for 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.

[0038] like Figure 4As shown, in order to conveniently control the powder material in the storage tank 200 to enter the feed box 201, this embodiment is modified on the basis of the above embodiment.

The feed discharge port 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 mounting 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 arranged in coordination with the plug-in plate 218. The plug-in slot 220 is arranged in coordination 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.

[0039] 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.

[0040] like Figures 2 to 3 As shown, in order to facilitate clamping of material bags, this embodiment is modified on the basis of the above embodiment, and the difference from the above embodiment is that a first connecting block 221 and a second connecting block 222 are respectively provided on both sides of the discharge funnel 210, and the first connecting block 221 and the second connecting block 222 are respectively fixedly connected to the two sides of the discharge funnel 210, and the pneumatic clamping structure 211 includes a first clamping structure 223 and a second clamping structure 224, the upper end of the first clamping structure 223 is rotatably connected to the first connecting block 221, and the upper end of the second clamping structure 224 is rotatably connected to the second connecting block 222, and a pair of clamping members 225 are provided between the first clamping structure 223 and the second clamping structure 224, and the clamping members 225 are respectively located on both sides of the bottom of the discharge funnel 210, and are arranged in coordination with the bottom of the discharge funnel 210.

[0041] Preferably, the first clamping structure 223 includes a pair of first clamping jaws 226 and a first pneumatic telescopic rod 227, the upper ends of the two first clamping jaws 226 are rotatably connected to the two ends of the first connecting block 221 respectively, and the first pneumatic telescopic rod 227 is arranged between the two first clamping jaws 226 for driving the first clamping jaws 226.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] like Figure 2 , Figure 5 , Figure 6 As shown, 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. The output end of the conveying motor 234 is connected to the conveyor belt 233 through a gear reversing box 235, which is used to drive the conveyor belt 233 to convey the powder material.

[0048] 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.

[0049] 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.

[0050] 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 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Preferably, a controller is also included, and the controller can adopt a PLC controller in the prior art.

[0057] Working principle of this utility model:

[0058] 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.

[0059] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. 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 utility model, which all belong to the protection scope of the utility model.
