Description

Technical Field

[0001] The present application relates to the technical field of packaging machines, and in particular to a powder packaging machine. Background Art

[0002] Powder packaging machine is a general term for packaging equipment for powder products. It is widely used in metal mines, pharmaceutical and chemical raw materials, dyes, kaolin, plastics and food processing fields. It has transformed the traditional manual packaging operation into the current automatic or semi-automatic packaging machine for filling.

[0003] During the powder filling process of the existing powder packaging machine, the air in the packaging bag is quickly discharged when the powder enters the packaging bag, causing powder to leak from the connection between the filling port and the filling bag, causing pollution to the surrounding environment and affecting the respiratory health of the staff. Utility Model Content

[0004] In order to reduce the possibility of powder leakage from the connection between the filling bag opening and the filling bag during the powder filling process of the powder packaging machine, the present application provides a powder packaging machine.

[0005] The powder packaging machine provided in this application adopts the following technical solution:

[0006] A powder packaging machine comprises a body placed on the ground, an operation panel arranged on one side of the body, a filling hopper installed on one side of the body, a placement table fixedly connected to the body on the side facing the filling hopper, and a filling auxiliary device installed between the filling hopper and the placement table for discharging gas in a powder packaging bag, wherein the filling hopper comprises a hopper fixedly connected to one side of the body and a discharge pipe fixedly connected to a discharge port of the hopper, the filling auxiliary device comprises an extrusion component installed on the placement table on a side close to the filling hopper for squeezing air out of the powder packaging bag, an exhaust component connected to the discharge pipe of the filling hopper, and a fastener arranged on the exhaust component for fixing the position of the powder packaging bag, and when the powder packaging bag is installed on the exhaust component, the interior of the powder packaging bag is connected to the outside and the discharge pipe at the same time.

[0007] By adopting the above technical solution, when in use, the staff places the powder packaging bag on the placement table, tightens the bag opening of the powder packaging bag at the discharge pipe through the fastener, controls the extrusion component to discharge the air in the powder packaging bag from the powder packaging bag to the outside through the exhaust component, and then starts the powder packaging machine to fill the powder into the powder packaging bag.

[0008] Optionally, the exhaust assembly includes a connection block fixedly connected to the discharge pipe and an exhaust pipeline arranged on the connection block, and the connection block is provided with an exhaust hole for inserting the exhaust pipeline and a discharge hole for the discharge pipe to pass through.

[0009] By adopting the above technical solution, when in use, the staff fixes the powder packaging bag on the side wall of the connecting block through the fastener, and the air in the powder packaging bag is discharged from the exhaust pipeline through the exhaust hole.

[0010] Optionally, the exhaust pipeline includes an exhaust pipe fixedly connected to the inner wall of the exhaust hole and a filter screen fixedly connected to an end of the exhaust pipe away from the filling hopper.

[0011] By adopting the above technical solution, when in use, the staff operates the extrusion component to discharge the air in the powder packaging bag from the exhaust pipe to the outside. When the staff fills the powder into the powder packaging bag, the powder hits the inner wall of the powder packaging bag under the action of gravity and scatters. At the same time, the air in the powder packaging bag is further squeezed by the powder and discharged from the exhaust pipe. The scattered powder is blocked by the filter net, so it will not be discharged to the outside through the exhaust pipe with the air to pollute the environment.

[0012] Optionally, the exhaust pipeline also includes a fixing frame fixedly connected to the side of the filter away from the placement table, and the fixing frame includes a connecting ring fixedly connected at the center of the filter and a connecting rod fixedly connected between the connecting ring and the exhaust pipe.

[0013] By adopting the above technical solution, when in use, the fixed filter plays a supporting role, thereby reducing the possibility of the filter being damaged by the impact of powder.

[0014] Optionally, the exhaust pipeline further includes an operating rod passing through the filter and a scraper fixedly connected to one end of the operating rod close to the placement table, and one side of the scraper abuts against a side of the filter close to the placement table.

[0015] By adopting the above technical solution, after the powder packaging machine in the present application has been used for a period of time, powder is easily accumulated on the side of the filter screen facing the placement table. The staff rotates the operating lever to drive the scraper to rotate, and the dust accumulated on the filter screen is scraped off by the scraper, so that the air in the powder packaging bag can be smoothly discharged from the powder packaging bag to the outside.

[0016] Optionally, the operating rod passes through the connecting ring, and the operating rod includes a limit block fixedly connected to the operating rod, and the limit block abuts against a side of the connecting ring away from the filter screen.

[0017] By adopting the above technical solution, under normal conditions, the limit block fixed on the operating rod abuts against the connecting ring, thereby ensuring that the operating rod will not slide from the middle of the connecting ring into the powder packaging bag.

[0018] Optionally, the operating rod also includes an auxiliary fixing part rotatably connected to the operating rod, the auxiliary fixing part includes a fixing ring fixedly connected to one end of the exhaust pipe close to the hopper, an upper limit ring sleeved on the operating rod, and a fixing rod fixedly connected between the fixing ring and the limit ring, and the operating rod is rotatably connected in the limit ring.

[0019] By adopting the above technical solution, the auxiliary fixing member determines the vertical position of the operating rod and limits the operating rod to rotate only in the horizontal direction, thereby preventing the scraper from scratching the filter screen due to factors such as the rotation angle of the operating rod.

[0020] Optionally, the extrusion assembly includes two mounting plates fixedly connected to the placing table on one side close to the filling hopper and arranged opposite to each other, cylinders fixedly connected to opposite sides of the two mounting plates, and extrusion plates fixedly connected to one end of the piston rods of the two cylinders, respectively. An extrusion space for extruding powder packaging bags is formed between the two extrusion plates, and the extrusion space is located directly below the exhaust assembly.

[0021] By adopting the above technical solution, when in use, the staff controls the cylinder so that the cylinder piston rod drives the extrusion plate to move, thereby squeezing out the air in the powder packaging bag.

[0022] Optionally, an electronic scale for weighing is provided on the side of the placement table facing the filling hopper, and a working signal of the electronic scale is connected to the operation panel.

[0023] By adopting the above technical solution, when in use, when the staff operates the powder packaging machine to fill the powder into the powder packaging bag, the electronic scale can weigh the weight in the powder packaging bag in real time. When the weight of the powder packaging bag reaches the set value, the operation panel receives the working signal of the electronic scale and stops filling the powder. At this time, the powder amount in the powder packaging bag meets the standard.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application sets a filling auxiliary device. When the powder packaging bag is fixed to the side wall of the connecting block by a fastener, the worker operates the extrusion assembly to discharge the air in the powder packaging bag to the outside through the exhaust pipe. At the same time, due to the setting of the filter screen, the powder in the powder packaging bag will not be discharged with the discharge of the air, reducing the possibility of environmental pollution caused by the overflow of powder;

[0026] 2. The present application sets an operating rod and a scraper in the exhaust pipe. After the staff uses the powder packaging machine in the present application, the staff rotates the operating rod so that the scraper rotates on the side of the filter with the operating rod as the axis, thereby timely cleaning the powder accumulated on the filter to prevent the powder from clogging the filter so that the air in the powder packaging bag cannot be discharged smoothly;

[0027] 3. This application sets an electronic scale on the placement table so that when the weight displayed by the electronic scale reaches the set value, the operation panel receives a signal from the electronic scale, thereby stopping the powder filling of the powder packaging machine. At the same time, during the powder filling process, the staff can observe the real-time weight of the powder packaging bag through the operation panel, so as to better control the total amount of powder in the powder packaging bag.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a powder packaging machine. Figure 1The powder packaging machine includes a body 1 placed on the ground, an operation panel 2 arranged on one side of the body 1, a filling hopper 3 installed on one side of the body 1, a filling auxiliary device 4 installed on the side of the filling hopper 3 facing the ground for fixing the powder packaging bag, and a placing table 5 fixedly connected to the side of the body 1 facing the filling hopper 3. The placing table 5 is located between the filling auxiliary device 4 and the ground. The filling hopper 3 includes a hopper 31 fixedly connected to one side of the body 1 and a discharge pipe 32 fixedly connected to the discharge port of the hopper 31. The filling auxiliary device 4 includes an extrusion component 41 installed on the side of the placing table 5 close to the filling hopper 3 for squeezing the air of the powder packaging bag, an exhaust component 42 connected to the discharge pipe 32 of the filling hopper 3, and a fastener 43 for fixing the position of the powder packaging bag on the exhaust component 42. The fastener 43 can be a clamp 431, a rubber band, etc. In this application, the clamp 431 is used as an example for description.

[0035] When in use, the staff places the powder packaging bag on the upper surface of the placement table 5, puts the bag mouth of the powder packaging bag on the exhaust component 42, tightens the bag mouth around the exhaust component 42 through the clamp 431, operates the squeezing component 41 to squeeze the air in the powder packaging bag, and then injects the powder into the powder packaging bag. If there is residual gas in the powder packaging bag, the residual gas will be discharged from the powder packaging bag through the exhaust component 42. At this time, the staff can operate the powder packaging machine through the operation panel 2 to package the powder.

[0036] Reference Figure 2 and Figure 3 The exhaust component 42 includes a connecting block 421 fixedly connected to the discharge pipe 32 and an exhaust pipeline 422 arranged on the connecting block 421. The connecting block 421 is provided with an exhaust hole 4211 for the exhaust pipeline 422 to be inserted and a discharge hole 4212 for the discharge pipe 32 to pass through. The exhaust pipeline 422 includes an exhaust pipe 4221 fixedly connected to the inner wall of the exhaust hole 4211 and a filter screen 4222 fixedly connected to the end of the exhaust pipe 4221 away from the filling hopper 3. The filter screen 4222 can prevent the discharge of powder.

[0037] When the powder packaging machine is started and the powder is filled into the powder packaging bag from the discharge pipe 32, the powder will float around in the powder packaging bag after being impacted, and at the same time, the air in the powder packaging bag is squeezed by the powder and discharged from the exhaust pipe 4221. Under the action of the filter 4222, the exhaust pipe 4221 only allows air to pass through, and the powder is blocked, thereby reducing the possibility of powder escaping from the powder packaging bag during the filling process.

[0038] Among them, the filter net 4222 can be made of cloth for filtering.

[0039] Reference Figure 3 or Figure 4The exhaust pipe 422 also includes a fixing frame 423 fixedly connected to the side of the filter 4222 away from the placement table 5, the fixing frame 423 includes a connecting ring 4231 fixedly connected at the center of the filter 4222, and a connecting rod 4232 fixedly connected between the connecting ring 4231 and the exhaust pipe 4221. A plurality of connecting rods 4232 are arranged at intervals along the circumference of the connecting ring 4231.

[0040] When the powder is impacted and hits the filter 4222 with the movement of the air, the overall shape of the filter 4222 does not change significantly due to the setting of the fixing frame 423, thereby reducing the possibility of damage to the filter 4222 and increasing the service life of the filter 4222.

[0041] After being used for a period of time, powder may accumulate on the surface of the filter 4222, thereby blocking the mesh holes of the filter 4222, making it impossible for the air in the powder packaging bag to be discharged.

[0042] Reference Figure 2 and Figure 4 In order to clean the powder on the filter screen 4222 in time, the exhaust pipe 422 also includes an operating rod 424 passing through the filter screen 4222 and a scraper 425 fixedly connected to the end of the operating rod 424 close to the placement table 5. One side of the scraper 425 abuts against the side of the filter screen 4222 close to the placement table 5. The operating rod 424 passes through the connecting ring 4231, and the end of the operating rod 424 away from the scraper 425 extends out of the exhaust pipe 4221 to the outside. The operating rod 424 includes a limit block 426 fixedly connected to the operating rod 424, and the limit block 426 abuts against the side of the connecting ring 4231 away from the filter screen 4222 to prevent the operating rod 424 from slipping from the connecting ring 4231 into the powder packaging bag.

[0043] After the powder packaging machine has been used for a period of time, the staff operates the rotating operating rod 424 that is exposed to the outside of the exhaust pipe 4221 , and the scraper 425 rotates with the rotation of the operating rod 424 , thereby scraping off the powder attached to the surface of the filter screen 4222 .

[0044] Reference Figure 1 and Figure 2In order to better fix the position of the operating rod 424, the operating rod 424 also includes an auxiliary fixing member 427 rotatably connected to the operating rod 424, and the auxiliary fixing member 427 includes a fixing ring 4271 fixedly connected to one end of the exhaust pipe 4221 close to the hopper 31, a limiting ring 4272 sleeved on the operating rod 424, and a fixing rod 4273 fixedly connected between the fixing ring 4271 and the limiting ring 4272, and the operating rod 424 is rotatably connected to the limiting ring 4272. Obviously, the axis of the limiting ring 4272 coincides with the axis of the connecting ring 4231, thereby ensuring the installation stability of the operating rod 424.

[0045] Reference Figure 1 The extrusion assembly 41 includes two mounting plates 411 fixedly connected to the side of the placement table 5 close to the filling hopper 3 and arranged opposite to each other, cylinders 412 fixedly connected to the opposite sides of the two mounting plates 411, and extrusion plates 413 fixedly connected to one end of the piston rods of the two cylinders 412. An extrusion space for extruding the powder packaging bag is formed between the two extrusion plates 413. The extrusion space is located directly below the exhaust assembly 42. The cylinder 412 can be controlled by the operation panel 2.

[0046] When in use, the staff places the powder packaging bag in the extrusion space, starts the cylinder 412 through the control panel 2, and the extrusion space is gradually reduced under the drive of the piston rod of the cylinder 412, so that most of the gas in the powder packaging bag is discharged. Then the bag mouth of the powder packaging bag is fixed to the side wall of the connecting block 421 through the clamp 431, and the piston rod of the cylinder 412 is retracted, and then the powder is injected into the powder packaging bag. With the injection of powder, the residual gas in the powder packaging bag is also discharged from the exhaust pipe 4221, and the powder is blocked by the filter 4222 and will not be emitted to the outside until the powder filling work is completed.

[0047] In order to better confirm the weight of the powder in the powder packaging bag, an electronic scale 6 for weighing is arranged on the side of the placement table 5 facing the filling hopper 3. The working signal of the electronic scale 6 is connected to the operation panel 2 via Bluetooth. When the weight of the powder in the powder packaging bag reaches the preset weight, the operation panel 2 emits a completion prompt sound and controls the powder packaging machine to automatically stop filling.

[0048] The implementation principle of a powder packaging machine in the embodiment of the present application is as follows: the staff puts the powder packaging bag into the extrusion space, puts the bag mouth of the powder packaging bag on the connecting block 421, tightens the bag mouth of the distribution table packaging bag through the clamp 431, and the staff controls the operation panel 2 to start the cylinder 412, so that the extrusion space is gradually reduced. After the powder packaging bag is squeezed by the extrusion plate 413, the gas in the powder packaging bag is discharged from the exhaust pipe 4221. When a certain amount of air is discharged, the staff starts the powder packaging machine to fill the powder, and the powder enters the powder packaging bag. Then, the air in the powder packaging bag is further squeezed, so that the air in the powder packaging bag continues to be discharged from the exhaust pipe 4221. Driven by the air, the powder moves along with it and is finally blocked by the filter 4222. A part of the powder adheres to the surface of the filter 4222, and the other part falls back into the powder packaging bag. When the weight of the powder in the powder packaging bag reaches the preset weight, the powder packaging machine stops filling. When the powder packaging machine completes one filling, the staff rotates the operating lever 424, and the scraper 425 rotates accordingly to scrape off the powder attached to the filter 4222.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
