Description

Technical Field

[0001] The invention relates to the technical field of packaging machines, in particular to a dust-free powder packaging machine. Background Art

[0002] Powder packaging machine is suitable for fully automatic metering and packaging of various uniform particles and powders. It is widely used in many industries such as food, medicine, chemical industry, additives, etc. Powder packaging machine is an automated equipment specially used for packaging powdered materials. It can efficiently and accurately pack powder into packaging bags or containers, ensuring the packaging process is hygienic, fast and accurate.

[0003] The powder packaging machine currently used puts the powder into the packaging machine from the feed hopper, and then uses the packaging bag to bag, cut and seal it. However, since the powder particles are fine, there is a certain friction and cohesion between the particles, so that the powder can maintain a certain shape and is not easy to disperse. In addition, the powder particles are prone to generate static electricity in a dry environment, which makes the particles attract each other and increases the agglomeration. These factors lead to the powder being easily agglomerated and blocked in the feeding hopper of the packaging machine, which needs to be manually unblocked by the staff. This not only affects the processing efficiency, but also the powder is easily flying in the process of unblocking, which causes waste and affects the working environment. It has certain disadvantages. For this reason, we propose a dust-free powder packaging machine. Summary of the invention

[0004] The object of the present invention is to provide a dust-free powder packaging machine to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 6 As shown, the present invention provides a technical solution: a dust-free powder packaging machine, comprising a machine body 1 and a feed hopper 2 arranged on the top of the machine body 1, a dredging component 3 for dredging the feed hopper 2 is arranged on the feed hopper 2, and a driven part 4 for preventing powder from flying during dredging is arranged on the side and top of the feed hopper 2;

[0028] The driven part 4 includes: a cover plate 41, which is used to cover the top of the feed hopper 2 during the dredging process; a resistance rack 42, which is used to control the cover plate 41; a transmission gear 43, which is used to control the movement of the resistance rack 42; and a connecting member 44, which is used to ensure that even if the transmission gear 43 continues to rotate, the resistance rack 42 can only move upward a certain distance.

[0029] The cover plate 41 is hinged on the top of the feed hopper 2, and a spring piece 45 is fixed on the side of the cover plate 41. The end of the spring piece 45 away from the cover plate 41 is fixed to the right side of the feed hopper 2. A transmission gear 43 is rotatably installed on the right side of the feed hopper 2. The transmission gear 43 is meshed with a resistance rack 42. The resistance rack 42 is slidably installed on the right side of the feed hopper 2. A connecting piece 44 is provided at the bottom of the resistance rack 42. A return spring 46 is fixed to the bottom of the resistance rack 42. When the transmission gear 43 rotates, the resistance rack 42 is controlled to move upward. After the resistance rack 42 moves upward for a certain distance, it resists on the cover plate 41, so that the cover plate 41 is flipped over at the position hinged with the feed hopper 2. The cover plate 41 covers the top of the feed hopper 2 to prevent the powder inside the feed hopper 2 from flying during the dredging process, thereby playing a dust-free role.

[0030] The connecting member 44 includes a sliding rod 441, the top of which is fixed to the bottom of the interference rack 42, the sliding rod 441 passes through the sliding tooth 442 and is slidably connected to the sliding tooth 442, and a connecting spring 443 is fixed to the bottom of the sliding tooth 442, and one end of the connecting spring 443 away from the sliding tooth 442 is fixed to the sliding rod 441. When the interference rack 42 moves upward for a certain distance, the sliding tooth 442 meshes with the transmission gear 43, and when the teeth of the transmission gear 43 are in contact with the sliding tooth 442, the sliding tooth 442 moves upward. When there is no conflict, the sliding tooth 442 can be reset downward under the action of the connecting spring 443, so that the sliding tooth 442 moves back and forth up and down, and the interference rack 42 does not continue to move upward, so that even if the transmission gear 43 continues to rotate, the interference rack 42 will not continue to move upward, thereby avoiding affecting normal use.

[0031] The dredging assembly 3 includes a fixed plate 31, the left side of the fixed plate 31 is fixed to the right side of the feed hopper 2, the top of the fixed plate 31 is fixed with a motor 32, and a rotating rod 33 is fixed on the output shaft of the motor 32, the rotating rod 33 passes through the feed hopper 2 and is rotatably connected to the feed hopper 2, and a cam 34 is fixed to the end of the rotating rod 33 away from the motor 32, and a movable frame 35 is slidably installed on the inner side of the feed hopper 2, and a dredging rod 36 is fixed on the inner side of the movable frame 35, and a square groove 37 is opened on the right side of the movable frame 35, and the cam 34 is in the square groove 37. When it is necessary to dredge the powder material on the inner side of the feed hopper 2, by starting the motor 32, the motor 32 drives the rotating rod 33 and the cam 34 to rotate, and the cam 34 controls the movable frame 35 to move up and down by contacting the inner side of the square groove 37. The movable frame 35 moves up and down with the dredging rod 36 to dredge the powder material to avoid accumulation and blockage of the powder material, and there is no need for manual dredging by the staff, which is convenient to use.

[0032] The rotating rod 33 passes through the transmission gear 43 and is fixedly connected to the transmission gear 43. The end of the return spring 46 away from the abutment rack 42 is fixed to the top of the fixed plate 31. When the motor 32 is started and the movable frame 35 and the dredging rod 36 are controlled to perform a dredging operation, the transmission gear 43 can be driven to rotate, and the cover plate 41 is controlled by the abutment rack 42 to cover the top of the feed hopper 2. When the work is completed, the cover plate 41 can be reset and opened under the action of the spring piece 45, which is convenient for subsequent staff to add powder and is easy to use.

[0033] Based on the above implementation mode, the staff puts powder into the feed hopper 2, the machine body 1 starts to work, and uses the packaging bag to perform bagging, cutting and sealing operations. The packaging bag installed on the machine body 1 passes through the conveying port under the drive of the motor and the stretching of the traction wheel, and the cylinder drives the sub-and to surround it, and controls the sealing device to extrude and seal the packaging bag, and then blows the sealed packaging bag to make the packaging bag bulge, and then the powder is added, and the packaging is completed by cutting after the addition is completed.

[0034] When the feed hopper 2 is blocked, the motor 32 is started, and the motor 32 drives the rotating rod 33 and the cam 34 to rotate. The cam 34 contacts the inner side of the square groove 37 to control the movable frame 35 to move up and down. The movable frame 35 moves up and down with the dredging rod 36 to dredge the powder to avoid the accumulation of powder and blockage. There is no need for manual dredging by the staff, which is convenient to use.

[0035] At the same time, the rotating rod 33 drives the transmission gear 43 to rotate, and the transmission gear 43 controls the abutment rack 42 to move upward. After the abutment rack 42 moves upward for a certain distance, it abuts on the cover plate 41, so that the cover plate 41 flips over at the position hinged with the feed hopper 2. The cover plate 41 covers the top of the feed hopper 2 to prevent the powder inside the feed hopper 2 from flying during the dredging process, thereby playing a dust-free role.

[0036] When the interference rack 42 moves upward for a certain distance, the sliding tooth 442 meshes with the transmission gear 43. When the teeth of the transmission gear 43 interfere with the sliding tooth 442, the sliding tooth 442 moves upward. When there is no interference, the sliding tooth 442 can be reset downward under the action of the connecting spring 443, so that the sliding tooth 442 moves back and forth up and down, and the interference rack 42 does not continue to move upward, so that even if the transmission gear 43 continues to rotate, the interference rack 42 will not continue to move upward, thereby avoiding affecting normal use.

[0037] After the work is finished, the cover plate 41 can be reset and opened under the action of the spring 45, so that subsequent workers can add powder materials, which is convenient for use.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
