Description

Technical Field

[0001] The present invention relates to the technical field of packaging machines, in particular to a fully servo-driven bag-feeding packaging machine. Background Art

[0002] A packaging machine is a device that can classify and package products, playing a role in protecting the products or beautifying their surface. Existing packaging machines are roughly divided into two categories: assembly line packaging machines and product peripheral packaging machines. Through the setting of the packaging machine, different products can be packaged quickly and orderly, which makes it easier to pack and transport the products. At the same time, the packaging machine can also seal the product as a whole to prevent the product from becoming corrupt or deteriorating during transportation.

[0003] At present, when transporting packaging bags, the bag-feeding packaging machines on the market use rubber rollers for transmission, and static electricity exists between the packaging bags, which may cause adsorption during transportation, resulting in two packaging bags being transported at a time, thereby disrupting the transmission rhythm of the packaging bags. At the same time, the existing bag-feeding packaging machines can only limit the loading of packaging bags of fixed sizes and cannot adapt to the placement of packaging bags of different sizes. Therefore, a device is needed to improve the above problems. Summary of the Invention

[0036] like Figure 7 The receiving component 6 includes a positioning transmission device 24 and a picking device 25. The positioning transmission device 24 is fixedly installed on the top of the front end of the picking device 25, which can support the positioning transmission device 24 to perform guided transmission work.

[0037] like Figure 8 The alignment transmission device 24 includes a U-shaped support base 26, a second positioning bolt 27, a sliding key 28, a synchronous limiting frame 29, a support vertical rod 30, a servo motor 31, a first transmission gear 32, a transmission belt 33, a second transmission gear 34 and a hexagonal rod 35. The servo motor 31 is fixedly mounted on the side end of the support vertical rod 30, and the hexagonal rod 35 is rotatably mounted between the two support vertical rods 30. The first transmission gear 32 and the second transmission gear 34 are respectively slidably sleeved on the hexagonal rod 35, and the transmission belt 33 is engaged with the outer rings of the first transmission gear 32 and the second transmission gear 34. On the top, the synchronous limiting frame 29 is equidistantly slidably sleeved on the hexagonal rod 35, and the synchronous limiting frame 29 is located on both sides of the transmission toothed belt 33, the U-shaped support base 26 is fixedly installed at the bottom center of the synchronous limiting frame 29, the sliding key 28 is symmetrically fixedly installed on the bottom end of the U-shaped support base 26, and the second positioning bolt 27 is threadedly inserted into the outer bottom end of the U-shaped support base 26 away from the transmission toothed belt 33. The inner bottom end of the U-shaped support base 26 is spaced 5 cm from the bottom end of the transmission toothed belt 33 to prevent the transmission toothed belt 33 from interfering with the U-shaped support base 26 during rotation.

[0038] like Figure 9The picking device 25 includes a docking guide rod 36, a return spring 37, a support base 38, a pneumatic suction cup 39, a sleeve 40, a U-shaped extension frame 41 and a hydraulic cylinder 42. The hydraulic cylinder 42 is equidistantly fixedly installed on the front bottom of the support base 38, the pneumatic suction cup 39 is fixedly installed on the top of the hydraulic cylinder 42, the U-shaped extension frame 41 is fixedly installed on the front center of the pneumatic suction cup 39, the sleeve 40 is fixedly installed on both sides of the rear end of the U-shaped extension frame 41, the return spring 37 is fixedly installed on the inner top of the sleeve 40, the docking guide rod 36 slides through the sleeve 40 and is fixedly installed on the bottom end of the return spring 37. Through the elasticity of the return spring 37, 336 is allowed to move downward again after contacting the button switch 3.

[0039] The mounting block 2 is symmetrically fixedly mounted on the front bottom of the support base 38, the front baffle 4 is fixedly mounted on the top front end of the support base 38, and the button switch 3 is symmetrically fixedly mounted on the front end of the support base 38 close to the mounting block 2, and the button switch 3 is located below the docking guide rod 36, which can support the button switch 3 to dock with the docking guide rod 36.

[0040] The limiting side plate 12 and the supporting side frame 13 are respectively slidably connected to the second track 17, the supporting frame 18 is fixedly installed on the front bottom of the front baffle 4, the front end of the limiting side plate 12 is fixedly installed on the top of the connecting rod 19, and the supporting vertical rod 30 is symmetrically fixedly installed on the front top of the supporting base 38, which can support the hexagonal rod 35 to rotate.

[0041] A guide hole that matches the limiting cross bar 16 is provided at the top center of the limiting side plate 12, the supporting side frame 13 is vertically aligned with the pressing frame 15, the front end surface of the supporting frame 18 is marked with scale lines, and the pointer 20 is vertically aligned with the scale lines. When the limiting side plate 12 moves, it can drive the pointer 20 to move, which is convenient for accurately controlling the moving distance of the limiting side plate 12.

[0042] The bottom end of the pressing frame 15 and the inner surface of the synchronous limiting frame 29 near the transmission belt 33 are both rotatably installed with ball bearings. The support base 38 is provided with a card slot compatible with the slide key 28 near the front top of the pneumatic suction cup 39. Circular holes are provided inside the two ends of the synchronous limiting frame 29, and the diameter of the circular hole is larger than the diameter of the hexagonal rod 35. There is an electrical connection between the button switch 3 and the pneumatic suction cup 39. The pneumatic suction cup 39 is vertically aligned with the internal center of the support frame 18. A plastic gasket is fixedly installed at the bottom center of the second positioning bolt 27, and the plastic gasket is vertically aligned with the support base 38. The length of the hexagonal rod 35 is less than the length of the internal recess of the U-shaped extension frame 41 to prevent the U-shaped extension frame 41 from interfering with the hexagonal rod 35 when moving up and down.

[0043] The working principle of Example 1 is as follows: when in use, the packaging bags are first stacked neatly and placed on the top ends of the two supporting side frames 13, and then the hydraulic cylinder 42 is started to drive the pneumatic suction cup 39 to move upward to contact the bottom end of the packaging bag. At the same time, when the pneumatic suction cup 39 is rising, it can drive the sleeve 40 to move upward synchronously, causing the docking guide rod 36 to disengage from the button switch 3. At this time, there is an electrical connection between the button switch 3 and the pneumatic suction cup 39, so that the air valve inside the pneumatic suction cup 39 will be started to absorb gas. When the pneumatic suction cup 39 contacts the bottom end of the packaging bag, the packaging bag can be adsorbed. Afterwards, the hydraulic cylinder 42 is started again to drive the U-shaped extension frame 41 to move downward, so that the pneumatic suction cup 39 can pull the packaging bag downward. At the same time, the limiting cross bar 16 is slidably inserted between the two limiting side plates 12, so that the pressable packaging bag is always kept in a downward state. At the same time, the pressing frame 15 is vertically aligned with the supporting side frame 13, so that the center of gravity of the limiting cross bar 16 can be concentrated on the pressing frame 15, and the two sides of the packaging bag can be pressed, thereby ensuring that the pneumatic suction cup 39 can only suck up one packaging bag at a time. At the same time, when the pneumatic suction cup 39 moves downward, it can drive the U-shaped extension frame 41 to move downward synchronously. The length of the concave part of the U-shaped extension frame 41 is greater than the length of the hexagonal rod 35, so that the U-shaped extension frame 41 can be prevented from interfering with the hexagonal rod 35 when moving up and down. At the same time, during the descent of the U-shaped extension frame 41, the docking guide rod 36 can be driven to engage with the button opening in advance. When the pneumatic suction cup 39 is in contact with the button switch 3, the pressing force of the reset spring 37 is greater than the spring tension inside the button switch 3, so that the pneumatic suction cup 39 can drive the docking guide rod 36 to contact the button switch 3 during the descent process, resulting in the air supply inside the pneumatic suction cup 39 being cut off, so that the pneumatic suction cup 39 can no longer generate suction. At this time, when the pneumatic suction cup 39 moves downward to the limit position, it can drive the packaging bag to contact the top surface of the transmission toothed belt 33, and the servo motor 31 can be started to drive the hexagonal rod 35 to rotate. The hexagonal rod 35 is slidably inserted into the inside of the first transmission gear 32, and a plastic sheet is fixedly installed on the outer ring surface of the transmission toothed belt 33, so that when the transmission toothed belt 33 rotates, it can drive the packaging bag to be transported to the rear end, completing the work of guiding the transportation of the packaging bag. When making packaging bags of different sizes, the gear 22 can be rotated to drive the rack 21 to move inward or outward, so that the connecting rod 19 will drive the limiting side plate 12 to move at the same time. In the process of limiting the movement of the side plate 12, the pointer 20 can be moved on the scale line on the front end of the support frame 18, so that the user can accurately control the movement distance of the limiting side plate 12. At the same time, the limiting side plate 12 and the supporting side frame 13 are respectively slidably connected to the outer ring of the second track 17, so that the limiting side plate 12 can be ensured to move in a straight line, the movement accuracy of the limiting side plate 12 is improved, and the lateral adjustment of the limiting side plate 12 is completed. At the same time, the pressing frame 15 is slidably connected to the first track 11, and the pressing frame 15 is located on the opposite side of the limiting side plate 12.When the limiting side plate 12 moves, it can also drive the pressing frame 15 to move synchronously, so that it can always be aligned with the top of the supporting side frame 13. At this time, the L-shaped pull rod 14 can be pushed to the rear end until the L-shaped pull rod 14 squeezes the packaging bag and contacts the surface of the front baffle 4, thereby limiting the alignment of the packaging bag to prevent the packaging bag from being skewed. At the same time, the first positioning bolt 9 can be screwed down to be fastened to the L-shaped pull rod 14, thereby preventing the L-shaped pull rod 14 from sliding again. After the limiting side plate 12 is adjusted, the U-shaped supporting base frame 26 can be moved at the same time, and the sliding key 28 can be slid in the card groove in the front top of the support base 38, so that the U-shaped supporting base frame 26 can be ensured to move in a straight line. At the same time, when the U-shaped supporting base frame 26 moves, it can drive the synchronous limiting frame 29 The synchronous limiting frame 29 moves simultaneously, so that the synchronous limiting frame 29 can push the first transmission gear 32, the second transmission gear 34 and the transmission toothed belt 33 to slide and adjust on the hexagonal rod 35 until the spacing between the two transmission toothed belts 33 corresponds to the size of the packaging bag. Then, the second positioning bolt 27 is screwed down until it is tightened with the support base 38, thereby improving the docking accuracy between the transmission toothed belt 33 and the packaging bag. When the first transmission gear 32 and the second transmission gear 34 rotate, the ball bearings installed on the relative inner surfaces of the synchronous limiting frame 29 rotate and fit with the first transmission gear 32 and the second transmission gear 34, so that the first transmission gear 32 and the second transmission gear 34 are prevented from being misaligned while not affecting the rotation of the first transmission gear 32 and the second transmission gear 34, thereby completing the guided transportation work adapted to different packaging bags.

[0044] Example 2

[0045] On the basis of Example 1, Figure 10 As shown, the limiting side plate 12 also includes an observation window 43, a support shaft 44, a magnet sheet 45, an iron rod 46 and a mounting hole 47. The mounting holes 47 are symmetrically arranged inside the two ends of the limiting side plate 12, and the support shaft 44 is rotatably mounted on the inner side opposite to the mounting hole 47. The observation window 43 is fixedly mounted on the support shaft 44, and the magnet sheet 45 is symmetrically fixedly mounted on the outer side of the observation window 43 away from the support shaft 44. The iron rod 46 is fixedly mounted on the inner end of the mounting hole 47 close to the magnet sheet 45.

[0046] When implementing this embodiment, the support shaft 44 is rotatably installed inside the mounting hole 47, so that the observation window 43 can be supported to rotate at an angle, thereby opening the inside of the mounting hole 47. The user can operate the stacked packaging bags through the limiting side plate 12. At the same time, when the observation window 43 is rotated inwardly to the extreme position, the magnet sheet 45 can be driven to fit with the iron rod 46, so that the magnet sheet 45 can be adsorbed on the surface of the iron rod 46, and the observation window 43 can be kept closed.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
