Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and specifically relates to a dust removal device for a vertical packaging machine. Background Technology

[0002] Vertical packaging machines are machines for packaging products. If the product being packaged is powder, dust can easily fly around at the feeding port and bag opening of the packaging machine. To avoid this, a dust removal device is needed to remove the dust.

[0003] Currently, there are various dust removal devices on the market. For example, a negative pressure pipe is installed on the surface of the feeding pipe. Through an external negative pressure device, the negative pressure pipe generates negative pressure, which sucks away the dust floating on the surface of the feeding pipe. Although it can achieve the purpose of dust removal, there are still some problems in its use. For example, this type of dust removal device needs to be used with an external air source. Without an external air source, the negative pressure pipe cannot generate suction. It cannot be linked with the feeding hopper during use, and the operating cost is relatively high. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for a vertical packaging machine, which has the advantages of energy saving and easy cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dust removal device for a vertical packaging machine, including a feeding hopper, a feeding pipe connected to the bottom of the feeding hopper, a dust collection hopper provided on the surface of the feeding hopper, a drive motor provided on the top of the feeding hopper, a mounting base fixedly connected between the feeding hopper and the dust collection hopper, a first rod rotatably connected to the top of the mounting base, a first transmission mechanism provided between the output end of the drive motor and the first rod, a second rod rotatably connected to the top of the dust collection hopper, one end of the second rod penetrating into the interior of the dust collection hopper and fixedly sleeved with a negative pressure fan blade, a second transmission mechanism provided between the first rod and the second rod, a filter mechanism provided inside the dust collection hopper, symmetrically arranged sliding rods on the top of the dust collection hopper, one end of the sliding rod penetrating into the interior of the dust collection hopper and fixedly sleeved with a limit block, a return spring sleeved with the sliding rod engaging between the limit block and the dust collection hopper, and a handle fixedly connected between the two sliding rods.

[0006] The above technical solution is adopted as follows: Under the action of the first transmission mechanism and the second transmission mechanism, the drive motor can drive the second rod to rotate, so that the negative pressure fan blades on the second rod can rotate. No external air source and drive equipment are required. It relies on the drive source built into the hopper to drive, which reduces the production cost and the cost during use. Through the design of the slide bar, when the handle is pulled upward, the return spring is compressed. When the handle is released, under the action of the return spring, the slide bar impacts into the dust collection hopper, causing it to hit the sliding seat of the filter mechanism. The vibration generated by the impact shakes off the dust adhering to the dust screen, eliminating the need to disassemble the dust screen for cleaning, which facilitates cleaning.

[0007] The present invention is further configured such that a conveying auger is rotatably connected inside the hopper, and one end of the conveying auger shaft extends through to the outside of the hopper and is bolted to the output end of the drive motor.

[0008] Using the above technical solution: when the drive motor starts, it can drive the conveying auger to rotate, which can transport the powder inside the hopper to the feeding pipe, and then transport it to the packaging bag through the feeding pipe.

[0009] The present invention is further configured such that the first transmission mechanism includes two synchronous gears, the two synchronous gears are respectively fixedly sleeved with the output end of the drive motor and the first rod body, and a synchronous toothed belt is transmitted between the two synchronous gears.

[0010] The above technical solution is adopted as follows: when the drive motor starts, it can drive the synchronous gear on the output shaft of the drive motor to rotate. Under the action of the synchronous toothed belt, it can drive the synchronous gear on the first rod to rotate, thereby driving the first rod to rotate.

[0011] The present invention is further configured such that the second transmission mechanism includes a third rod disposed between the first rod and the second rod and rotatably connected to the dust collection hopper, a large gear is fixedly sleeved on the surface of the first rod, a medium gear meshing with the large gear is fixedly sleeved on the surface of the third rod, and a small gear meshing with the medium gear is fixedly sleeved on the surface of the second rod.

[0012] The above technical solution is as follows: When the first rod is driven to rotate under the action of the first transmission mechanism, it can drive the large gear to rotate. The rotation of the large gear can drive the middle gear on the third rod to rotate. The rotation of the middle gear can drive the small gear to rotate. In turn, the small gear drives the second rod to rotate. The rotation of the second rod drives the negative pressure fan blades inside the dust collection hopper to rotate, thereby achieving the purpose of generating negative pressure inside the dust collection hopper. Furthermore, through the gear ratio of the large gear, middle gear, and small gear, the drive motor rotates one revolution, and the small gear drives the second rod to rotate several revolutions. Thus, when the negative pressure fan blades rotate, negative pressure suction is generated inside the dust collection hopper.

[0013] The present invention is further configured such that the filtration mechanism includes an installation groove formed on the dust collection hopper, a sliding seat is slidably connected inside the installation groove, and a dustproof net is assembled inside the sliding seat.

[0014] By adopting the above technical solution, the dust entering the dust collection hopper can be filtered to prevent the dust from being discharged from the dust collection hopper.

[0015] The present invention is further configured such that a dust suction chamber is provided on the feeding pipe, a dust suction hole communicating with the dust suction chamber is provided on the surface of the feeding pipe, and a dust suction pipe is connected between the dust suction chamber and the dust collection hopper.

[0016] The above technical solution facilitates the negative pressure inside the dust collection hopper to act on the dust suction chamber, allowing external dust to be adsorbed into the dust suction chamber through the dust suction holes and then transported to the dust collection hopper through the dust suction pipe.

[0017] The present invention is further configured such that the top of the hopper is connected to an external feed pipe, and the top of the dust collection hopper is connected to an exhaust pipe.

[0018] The above technical solution facilitates the conveying of external powder materials into the hopper and facilitates the exhaust of air from inside the dust collection hopper.

[0019] The present invention is further configured such that the surface of the drive motor is symmetrically fitted with a bracket that is bolted to the hopper, the bottom of the dust collection hopper is connected to a ash discharge pipe, and a valve is installed on the surface of the ash discharge pipe.

[0020] The above technical solution is adopted to fix and limit the drive motor and facilitate the discharge and recycling of dust inside the dust collection hopper.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. Under the action of the first transmission mechanism and the second transmission mechanism, the drive motor can drive the second rod to rotate, so that the negative pressure fan blades on the second rod can rotate. No external air source and drive equipment are required. It is driven by the drive source built into the hopper, which reduces the production cost and the cost of use.

[0023] 2. This utility model uses a sliding rod design. When the handle is pulled upward, the return spring is compressed. When the handle is released, the sliding rod impacts the dust collection hopper under the action of the return spring, causing it to strike the sliding seat of the filter mechanism. The vibration generated by the impact shakes off the dust adhering to the dust screen, eliminating the need to disassemble the dust screen for cleaning, thus facilitating cleaning.

A suction pipe 19 connects the suction chamber 17 and the dust collection hopper 3. By setting up the suction chamber 17, suction holes 18, and suction pipe 19, the negative pressure inside the dust collection hopper 3 can be applied to the suction chamber 17, drawing external dust into the suction chamber 17 through the suction holes 18 and then conveying it into the dust collection hopper 3 through the suction pipe 19. A drive motor 4 is installed at the top of the hopper 1, and a conveying auger 16 is rotatably connected inside the hopper 1. One end of the shaft of the conveying auger 16 extends to the outside of the hopper 1. The material is bolted to the output end of the drive motor 4. By setting up a conveying auger 16, when the drive motor 4 starts, it can drive the conveying auger 16 to rotate, conveying the powder inside the hopper 1 to the discharge pipe 2, and then through the discharge pipe 2 to the packaging bag. A mounting base 5 is fixedly connected between the hopper 1 and the dust collection hopper 3. A first rod 6 is rotatably connected to the top of the mounting base 5. A first transmission mechanism 7 is set between the output end of the drive motor 4 and the first rod 6. The first transmission mechanism 7 includes two synchronous gears 71, which are fixedly sleeved to the output end of the drive motor 4 and the first rod 6 respectively. A synchronous toothed belt 72 is connected between the two synchronous gears 71. By setting up the synchronous gears 71 and the synchronous toothed belt 72, when the drive motor 4 starts... Then, it can drive the synchronous gear 71 on the output shaft of the drive motor 4 to rotate. Under the action of the synchronous toothed belt 72, it can drive the synchronous gear 71 on the first rod 6 to rotate, thereby driving the first rod 6 to rotate. The top of the dust collection hopper 3 is rotatably connected to the second rod 8.

By configuring a third rod 101, a large gear 102, a medium gear 103, and a small gear 104, when the first rod 6 is driven to rotate under the action of the first transmission mechanism 7, it can drive the large gear 102 to rotate. The rotation of the large gear 102 can drive the medium gear 103 on the third rod 101 to rotate. The rotation of the medium gear 103 can drive the small gear 104 to rotate, which in turn drives the second rod 8 to rotate. The rotation of the second rod 8 drives the negative pressure fan blades 9 inside the dust collection hopper 3 to rotate, achieving the purpose of generating negative pressure inside the dust collection hopper 3. Furthermore, through the gear ratio of the large gear 102, medium gear 103, and small gear 104...When the drive motor 4 rotates once, the pinion 104 drives the second rod 8 to rotate several times, thereby generating negative pressure suction inside the dust collection hopper 3 when the negative pressure fan blade 9 rotates. The dust collection hopper 3 is equipped with a filter mechanism 11, which includes a mounting groove 111 on the dust collection hopper 3. A sliding seat 112 is slidably connected inside the mounting groove 111, and a dustproof net 113 is installed inside the sliding seat 112.

The dust is discharged internally from the dust hopper 3. An external feed pipe 20 is connected to the top of the feed hopper 1, and an exhaust pipe 21 is connected to the top of the dust hopper 3. The external feed pipe 20 and exhaust pipe 21 facilitate the conveying of external powder materials into the feed hopper 1 and the venting of dust from the dust hopper 3. A retainer 22, which is bolted to the feed hopper 1, is symmetrically mounted on the surface of the drive motor 4. A ash discharge pipe 23 is connected to the bottom of the dust hopper 3, and a valve is installed on the surface of the ash discharge pipe 23. The retainer 22 and ash discharge pipe 23 fix and limit the drive motor 4 and facilitate the discharge and recovery of dust from inside the dust hopper 3.
