Description

Technical Field

[0001] This application relates to the technical field of packaging machines, and in particular to a fully automatic packaging machine. Background Technology

[0002] Currently, packaging machines are mechanical devices used to seal products in appropriate packaging materials, and are widely used in many industries such as food, beverage, pharmaceutical, chemical, and daily necessities.

[0003] Among the related technologies, there is a packaging machine for packaging small connectors. Its structure mainly includes a product feeding mechanism, a bag feeding mechanism, a bag opening mechanism, and a sealing mechanism. During operation, the bag feeding mechanism feeds the packaging bags one by one into the bag opening mechanism, which then opens the bag opening. Next, the product feeding mechanism feeds the product into the packaging bag in a quantitative manner. Finally, the sealing mechanism heat-seals the bag opening. After the bag opening is heat-sealed, a new round of packaging work begins.

[0004] For the aforementioned packaging machine, due to the limitations of the coordination, operation mode and layout between various mechanisms, a new round of packaging work can only be restarted after the sealing mechanism has finished heat-sealing the bag opening. This results in other mechanisms being idle during the heat-sealing period, which reduces packaging efficiency to some extent and makes it difficult to meet the needs of factories for large-volume packaging.

[0016] Preferably, the bagging hopper is lifted and mounted on the mounting frame, and a flap is rotatably mounted at the bottom of the bagging hopper. The flaps are symmetrically arranged on both sides of the bottom discharge port of the bagging hopper. A limit frame is provided on the mounting frame, and a limit plate is provided on the flap. The limit frame is located on the lifting path of the limit plate. The limit plate is used to contact the limit frame and drive the flap to open the bottom discharge port of the bagging hopper.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a fully automatic packaging machine.

[0035] Reference Figure 1 , Figure 2 The fully automatic packaging machine includes a product feeding mechanism 1, a bag feeding mechanism 2, a bag clamping assembly 3, a bag opening mechanism 4, a sealing mechanism 5, a sliding seat 6, and a discharge mechanism 7. The product feeding mechanism 1 is used to periodically convey products to be packaged, and the bag feeding mechanism 2 is used to periodically convey packaging bags. The bag clamping assembly 3 is located below the discharge port of the product feeding mechanism 1 and is used to clamp and fix the individual packaging bags delivered by the bag feeding mechanism 2. The bag opening mechanism 4 is located between the bag feeding mechanism 2 and the bag clamping assembly 3, and is used to open the bag opening on the bag clamping assembly 3, ensuring that the product falls smoothly into the packaging bag. The sealing mechanism 5 is symmetrically arranged on both sides of the bag clamping assembly 3, and is used to heat-seal the bag opening.

[0036] like Figure 2 , Figure 3 As shown, the product feeding mechanism 1 includes a feeding frame 10 with an inlet for connection with the product vibratory feeder. A feeding belt 11 driven by a motor is rotatably mounted on the feeding frame 10. Multiple baffles 12 are arranged sequentially at intervals on the feeding belt 11. A receiving groove 13 for accommodating products is formed between two adjacent baffles 12. The baffles 12 located on both sides of the receiving groove 13 are used to limit the products within their respective receiving grooves 13. When the products in the receiving grooves 13 move to the outlet of the feeding frame 10, the products will fall from the outlet of the feeding frame 10 into the bag opening mechanism 4.

[0037] like Figure 3 , Figure 4As shown, the bag opening mechanism 4 includes a mounting frame 40, a bag filling chamber 41 mounted on the mounting frame 40, and a bag opening suction cup 42. The bag filling chamber 41 is vertically arranged, and the inlet at the top of the bag filling chamber 41 faces the outlet of the feed rack 10 above. Products falling from the outlet of the feed rack 10 will fall into the bag filling chamber 41 through the inlet.

[0038] like Figure 3 , Figure 4 As shown, the bagging chamber 41 is vertically raised and lowered on the mounting frame 40 under the drive of an external cylinder. Two flaps 43 are rotatably mounted at the bottom of the bagging chamber 41 to block the bottom discharge port. The flaps 43 are symmetrically arranged on both sides of the bottom discharge port of the bagging chamber 41. When the bagging chamber 41 is raised under the drive of the external cylinder, the flaps 43 will remain in a blocked state under their own weight.

[0039] like Figure 3 , Figure 4 As shown, a limiting frame 44 is fixedly installed on the mounting frame 40 outside the bagging chamber 41. A limiting plate 430 is fixedly installed on the outer wall of the flap 43 above the limiting frame 44. The limiting frames 44 are respectively located on the lifting paths of their respective limiting plates 430. When the bagging chamber 41 descends, the limiting plates 430 will be blocked by their respective limiting frames 44. Finally, the two flaps 43 will rotate in the direction of separation around their respective rotation axes under the blocking of the limiting frames 44, until the bottom discharge port of the bagging chamber 41 is opened. At this time, the product in the bagging chamber 41 can fall smoothly from the bottom discharge port of the bagging chamber 41.

[0040] like Figure 3 , Figure 4 As shown, the bag-opening suction cups 42 on the mounting frame 40 are symmetrically arranged on both sides of the discharge port of the bagging chamber 41. Driven by cylinders, the two bag-opening suction cups 42 are moved on the mounting frame 40 along the bag-opening direction. The bag-opening suction cups 42 are connected to suction pipes. When the bag opening needs to be opened, the two bag-opening suction cups 42 move synchronously towards each other under the drive of the cylinders until they adhere to the outer wall of the bag. Then, the suction pipes quickly draw air to create a negative pressure inside the bag-opening suction cups 42, at which point the two bag-opening suction cups 42 can firmly adhere to the outer wall of the bag. Subsequently, the two bag-opening suction cups 42 move synchronously towards each other until the bag opening is opened to the specified size. Then, the bagging chamber 41 is inserted downwards into the bag and completes the bagging process. Afterwards, the bagging chamber 41 quickly returns to its original position and begins a new round of bagging.

[0041] like Figure 2 , Figure 5As shown, the bag clamping assembly 3 is mounted on the sliding seat 6, and the sliding seat 6 has at least two sets of bag clamping assemblies 3. In this embodiment, the number of bag clamping assemblies 3 is two sets. The two sets of bag clamping assemblies 3 are symmetrically arranged on both sides of the sliding seat 6, and the bag clamping assembly 3 includes a pneumatic gripper. The sealing mechanism 5 is symmetrically arranged on both sides of the sliding seat 6. The sliding seat 6 is driven by an external drive source to periodically reciprocate between the two sealing mechanisms 5. In this embodiment, the sliding seat 6 is driven by a lead screw and a motor to slide. The sliding seat 6 is used to drive the bag clamping assembly 3 to move closer to or further away from its respective adjacent sealing mechanism 5.

[0042] like Figure 2 , Figure 4 as well as Figure 5 As shown, when one set of bag clamping components 3 moves with the sliding seat 6 to face the discharge port of the bag feeding mechanism 2, this set of bag clamping components 3 is at the bagging station and directly below the bagging bin 41. The bag clamping components 3 at the bagging station are used to clamp and fix the packaging bags fed out by the bag feeding mechanism 2, thereby ensuring the smooth bagging operation of the bagging bin 41. After the bagging operation is completed, the sliding seat 6 will drive the bag clamping components 3 at the bagging station to move closer to the adjacent sealing mechanism 5, and the sealing mechanism 5 will seal the packaging bag. At this time, another set of bag clamping components 3 will move to the bagging station again and start a new round of bagging operation. This cycle repeats, realizing the synchronous operation of sealing and bagging, greatly improving packaging efficiency, ensuring stable operation, and having a reasonable structural layout, which can meet the needs of large-volume packaging in factories.

[0043] like Figure 5 , Figure 6 As shown, the sealing mechanism 5 includes two sealing plates 50 arranged opposite each other. Driven by a cylinder, the sealing plates 50 move towards or away from each other. When the sliding seat 6 feeds the packaging bag between the two sealing plates 50, the sealing plates 50, driven by the cylinder, press the opening of the packaging bag tightly. A heat-sealing plate 51 is fixedly installed on the side wall of the sealing plate 50 facing the packaging bag, and the heat-sealing plate 51 is used to heat-seal the opening of the packaging bag.

[0044] like Figure 2 , Figure 6 As shown, the discharge mechanism 7 is located below each of the corresponding sealing mechanisms 5. The discharge mechanism 7 includes a conveyor belt driven by a motor. After the sealing mechanism 5 finishes sealing the packaging bag, as the sealing plates 50 on both sides open in the direction of separation, the packaging bag will fall onto the discharge mechanism 7 below and be sent out by the discharge mechanism 7.

[0045] like Figure 7 , Figure 8As shown, the bag feeding mechanism 2 includes a bag feeding seat 20, a bag winding reel 21, a cutter seat 22, and a bag feeding assembly 23. Rolled packaging bags are wound onto the bag winding reel 21, and the packaging bags pulled from the bag winding reel 21 are placed on the bag feeding seat 20. The cutter seat 22 is located above the packaging bag pulling path, and the cutter seat 22 is equipped with cutters for cutting the rolled packaging bags.

[0046] like Figure 7 , Figure 8 As shown, the cutter holder 22 is vertically mounted on the bag feeding seat 20 under the drive of a cylinder. The bag feeding mechanism 2 also includes a bag pulling seat 24 movably mounted on the bag feeding seat 20, located on the side of the cutter holder 22 opposite to the bag winding reel 21. The bag pulling seat 24 is equipped with pneumatic grippers and slides along the direction of bag pulling under the drive of a cylinder. After the cutter holder 22 completes the cutting of the packaging bag, the bag feeding assembly 23 removes the cut individual packaging bags from the bag feeding seat 20. Then, the cutter holder 22 rises and resets. Next, the bag pulling seat 24 drives the pneumatic grippers to move closer to the rolled packaging tape and clamps and fixes the end of the rolled packaging tape. Then, the bag pulling seat 24 pulls the packaging bag out from the bag winding reel 21 to the designated cutting station, and then begins a new round of cutting.

[0047] like Figure 7 , Figure 8 As shown, the bag feeding assembly 23 is located below the bag feeding seat 20 and is used to transport the cut individual packaging bags to the bag clamping assembly 3. The bag feeding assembly 23 includes a rotary motor 230, a bag-grabbing suction cup 231 mounted on the rotating shaft of the rotary motor 230, and a reversing motor 232 positioned between the bag clamping assembly 3 and the rotary motor 230. The rotating shaft of the rotary motor 230 is horizontally positioned, and the rotary motor 230 drives the bag-grabbing suction cup 231 to rotate vertically. The bag-grabbing suction cup 231 is also connected to an air extraction pipe, and the working principle of the bag-grabbing suction cup 231 is the same as that of the bag-opening suction cup 42, which will not be described in detail here. The bag-grabbing suction cup 231 can extend and retract along the radius of its own rotation path under the drive of an external cylinder.

[0048] like Figure 7 , Figure 8 As shown, the reversing motor 232 is located between the rotary motor 230 and the sliding seat 6. The rotation shaft of the reversing motor 232 is vertically arranged, and a transfer suction cup 233 is mounted on the rotation shaft of the reversing motor 232. The working principle of the transfer suction cup 233 is the same as that of the bag opening suction cup 42, and will not be described again here. The transfer suction cup 233 is also extended and retracted along the radius of its own rotation path under the drive of an external cylinder. The transfer suction cup 233 is used to receive a single packaging bag delivered from the bag picking suction cup 231 and deliver the packaging bag to the bag clamping assembly 3 located at the bag filling station.

[0049] The implementation principle is as follows: Product feeding mechanism 1 is used to periodically convey products to be packaged, and bag feeding mechanism 2 is used to periodically convey packaging bags. Bag clamping assembly 3 is located below the discharge port of product feeding mechanism 1 and is used to clamp and fix the individual packaging bags delivered by bag feeding mechanism 2. Bag opening mechanism 4 is set between bag feeding mechanism 2 and bag clamping assembly 3, and is used to open the bag opening on bag clamping assembly 3 and ensure that the product falls smoothly into the packaging bag. Sealing mechanism 5 is symmetrically arranged on both sides of bag clamping assembly 3 and is used to heat seal the bag opening. After sealing mechanism 5 completes sealing of packaging bag, as the sealing plates 50 on both sides open in the direction of separation, the packaging bag will fall onto the discharge mechanism 7 below, and the packaging bag will be delivered by the discharge mechanism 7.

[0050] After the bagging process is completed, the sliding seat 6 will move the bag clamping assembly 3 located at the bagging station towards the adjacent sealing mechanism 5, whereby the sealing mechanism 5 will seal the packaging bag. At this time, another set of bag clamping assemblies 3 will move back to the bagging station and begin a new round of bagging. This cycle repeats continuously, achieving simultaneous sealing and bagging, greatly improving packaging efficiency, ensuring stable operation, and having a reasonable structural layout, which can meet the needs of large-volume packaging in factories.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
