Description

Technical Field

[0001] The present invention relates to the field of sewing needle packaging, and specifically to a sewing needle packaging machine and its packaging production line. Background Art

[0002] Before sewing needles are sent out of the factory and into the hands of customers, the sewing needles need to be wrapped in packaging for convenient boxing. In the traditional packaging production line for sewing needles, when the bottom lining of the packaging bag is sent out, due to the lack of an anti-slip structure on the feeding belt, the bottom lining of the packaging is prone to slipping and displacement on the feeding belt. When the packaging bag is subsequently packaged, the bottom lining and the sealing layer of the packaging bag are prone to skew, which not only affects the appearance but also easily leaks the sewing needles. Moreover, when the sewing needles are sent out from the sewing needle cartridge, due to the lack of lubricating oil applied on the feeding rod, the sewing needles cannot smoothly reach the card slot of the feeding rod, affecting the subsequent grasping by the mechanical gripper.

[0003] In document CN 206013041 U, an automatic packaging machine for flat handle acupuncture needles in bags is disclosed. It includes a lower feeding mechanism, a color code printing mechanism, a needle separating mechanism, a branch pipe mechanism, an upper feeding mechanism, a heat sealing and forming mechanism, a traction mechanism, and a cold cutting and blanking mechanism connected in sequence. This is also a form of packaging for needles, but when the packaging is being conveyed, there is no anti-slip structure on the conveyor belt, which easily causes the packaging to skew during the final sealing. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a sewing needle packaging machine and its packaging production line, which can effectively prevent the packaging bag from skewing during the final packaging, and facilitate the sewing needles to be clamped into the screw one by one when the sewing needle cartridge is discharging materials.

[0005] The technical solution of the present invention is as follows: The sewing needle packaging machine includes a feeding structure, a printing structure, a sewing needle cartridge, a mechanical gripper, a sealing structure, a cutting structure, a blanking port, and a sewing needle conveyor belt. At the starting end of the conveyor belt, there is a printing silver tape. The feeding structure is located on both sides of the printing structure. The bottom lining feeding roll is on the side close to the printing silver tape, and the sealing layer feeding roll is on the other side. There are rubber stickers on the sewing needle conveyor belt. There is a screw between the conveyor belt and the sewing needle cartridge. There are lubricating blocks and paddles on the screw. There is a guiding structure between the bottom lining feeding roll and the printing structure. The guiding structure includes three guide rods in an inverted triangle shape.

[0006] Further, the screw is driven by an external motor. The distance between the threads on the screw is exactly the diameter of one sewing needle. The screw is perpendicular to the conveyor belt.

[0007] Further, the paddle is located above the screw, the end of the paddle contacts the screw, the position of the paddle near the end is rotationally connected to the frame, and the head end of the paddle is connected to the frame by a spring.

[0008] Further, the lubricating block is located between the paddle and the mechanical gripper, the lubricating block contacts the screw, a lubricating syringe is provided above the lubricating block, the tip of the lubricating syringe is exactly placed on the lubricating block, and the lubricating block is made of sponge.

[0009] Further, an electromagnetic suction is provided on the grasping surface on the side of the mechanical gripper close to the screw, and the width of the grasping surface of the mechanical gripper is an integer multiple of the sewing needle, and the integer multiple is 8 - 12 times.

[0010] Further, a flattening roller is provided between the sealing structure and the sealing layer feeding roll. The sealing structure includes a sealing surface, the sealing surface is a rectangular frame, the rectangular frame is a heating plate, and the rectangular frame is exactly located outside the sewing needle, on the inner sides of the substrate and the sealing layer.

[0011] Further, the cutting structure includes a cutting knife controlled by a cylinder, and the distance between the cutting knife and the sealing surface is an integer multiple of the rectangular frame of the sealing surface, and the integer multiple is 2 - 3 times.

[0012] The packaging production line of the sewing needle packaging machine includes the following steps:

[0013] Step 1: The printing silver tape is conveyed from one side of the conveyor belt to the lower part of the printing plate of the printing structure. At the same time, the substrate feeding roll covers the substrate above the printing silver tape. Then the printing plate moves downward to strike the raised fonts and numbers at the bottom of the printing plate onto the substrate, and silver fonts and numbers are printed on the bottom of the substrate.

[0014] Step 2: At the same time, the sewing needles in the sewing needle cartridge rotate with the screw, and the sewing needles sequentially and orderly fall onto the threads of the screw from the sewing needle cartridge. After being sorted by the paddle, it is ensured that each sewing needle is located on the thread of the screw, and the lubricating oil dripped through the tip of the needle on the lubricating block just enables the lubricating block to lubricate the screw.

[0015] Step 3: The mechanical gripper moves towards the screw. The mechanical gripper is energized to have magnetic suction, and it sucks the sewing needles delivered from the screw. Then the mechanical gripper moves towards the conveyor belt. When the mechanical gripper moves above the conveyor belt and is close to the conveyor belt, the power is cut off, the mechanical gripper loses magnetism, and the sewing needles fall from the mechanical gripper onto the substrate.

[0016] Step 4: The conveyor belt drives the substrate to continue running. The sealing layer feeding roll releases the sealing layer, and the sealing layer passes through the flattening roller to press the sealing layer onto the sewing needles on the substrate. Before reaching the sealing structure, the substrate and the sealing layer always remain in contact.

[0017] Step 5: When the conveyor belt transports the substrate and the sealing layer to the bottom of the sealing structure, the sealing surface of the sealing structure is pressed downward. However, since the rectangular frame of the sealing surface is a heating plate, the heating plate adheres the sealing layer and the substrate together at high temperature, and the machine needle is covered between the sealing layer and the substrate;

[0018] Step 6: The conveyor belt transports the sealed packaging bags to the bottom of the cutting structure. The cutting knife of the cutting structure cuts the packaging bags between the needles in the direction of the conveyor belt. Finally, the packaging bags with needles fall into the collection bucket from the drop port.

[0019] Advantages of the present invention: 1. The present invention arranges rubber stickers on the conveyor belt. When the substrate is conveyed to the conveyor belt, the rubber stickers on the conveyor belt play an anti-slip role for the substrate, preventing the substrate from shifting on the conveyor belt and affecting the subsequent sealing operation.

[0020] 2. The present invention arranges a screw at the bottom of the needle box so that when the screw rotates, the needle at the bottom of the needle box is brought out and is just clamped in the thread of the screw, making it convenient for the mechanical gripper at the back to grab the needle.

[0021] 3. The present invention can ensure that the needle is always kept in the screw by setting a paddle. Even if the screw is offset when it is rotated out of the needle box, the paddle can move the needle on the screw so that it is just stuck in the thread of the screw.

[0022] 4. The present invention provides a lubrication block on the screw to ensure that the rotating screw can be dipped into lubricating oil on each circumference, which can play a smooth role when the machine needle is clamped in the thread. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] As Figure 1-6 shown, a needle packaging machine includes a feeding structure, a printing structure, a needle cartridge, a mechanical gripper 10, a sealing structure, a cutting structure, a discharge opening 13, and a needle conveyor belt 1. At the beginning end of the conveyor belt 1, there is a printed silver tape. The feeding structure is located on both sides of the printing structure. The substrate feeding roll 2 is on the side close to the printed silver tape, and the sealing layer feeding roll 9 is on the other side. There is a rubber sticker 1-1 on the needle conveyor belt 1. There is a screw 6 between the conveyor belt 1 and the needle cartridge 5. There are a lubricating block 7 and a paddle 8 on the screw 6. There is a guiding structure between the substrate feeding roll 2 and the printing structure. The guiding structure includes three guide rods 3 in an inverted triangle shape. The guide rods 3 can guide the substrate sent out by the substrate feeding belt 2 to ensure that when the substrate is placed on the conveyor belt 1, it is parallel to the edge of the conveyor belt 1.

[0032] The screw 6 is driven by an external motor. The distance between the threads on the screw 6 is exactly the diameter of a needle. The screw 6 is perpendicular to the conveyor belt 1. The screw 6 can arrange the needles 14 coming out of the needle cartridge 5 in sequence. The needles 14 are exactly clamped in the threads of the screw 6.

[0033] The paddle 8 is located above the screw 6. The end of the paddle 8 contacts the screw 6. The position of the paddle 8 close to the end is rotationally connected to the frame. The head end of the paddle 8 is connected to the frame by a spring. The paddle can ensure that the needles always remain in the threads of the screw 6 and prevent the needles 14 from being between the threads.

[0034] The lubricating block 7 is located between the paddle 8 and the mechanical gripper 10. The lubricating block 7 contacts the screw 6. There is a lubricating syringe 7-1 above the lubricating block 7. The tip of the lubricating syringe 7-1 is exactly placed on the lubricating block 7. The lubricating block 7 is made of sponge. The lubricating block 7 can lubricate the screw 6 to make it smooth when the needles 14 are clamped in the threads.

[0035] On the grasping surface on one side where the mechanical gripper 10 approaches the screw 6, there is an electromagnetic suction. The width of the grasping surface 10-1 of the mechanical gripper 10 is an integer multiple of the sewing needle 14, and the integer multiple is 8-12 times. The mechanical gripper 10 can grasp the sewing needle 14 from the screw 6 onto the substrate, facilitating the packaging of the sewing needle 14 by the packaging bag.

[0036] There is a flattening roller between the sealing structure and the sealing layer feeding roll 9. The sealing structure includes a sealing surface 11, and the sealing surface 11 is a rectangular frame. The rectangular frame is a heating plate and is exactly located outside the sewing needle 14 and inside the substrate and the sealing layer. The sealing structure can melt and fix the substrate and the sealing layer, so that the sewing needle 14 is always between the substrate and the sealing layer.

[0037] The cutting structure includes a cutting knife 12 controlled by a cylinder. The distance between the cutting knife 12 and the sealing surface 11 is an integer multiple of the rectangular frame of the sealing surface 11, and the integer multiple is 2-3 times. The cutting knife cuts off the substrate and the sealing layer between the connected sewing needles 14, facilitating subsequent boxing.

[0038] The packaging production line of the sewing needle packaging machine includes the following steps:

[0039] Step 1: The printing silver tape is conveyed from one side of the conveyor belt 1 to the lower part of the printing plate 4 of the printing structure. At the same time, the substrate feeding roll 2 covers the substrate above the printing silver tape. Then the printing plate 4 moves downward to strike the fonts and numbers protruding from the bottom of the printing plate 4 onto the substrate, and silver fonts and numbers are printed on the bottom of the substrate.

[0040] Step 2: At the same time, as the screw 6 rotates, the sewing needles 14 in the sewing needle cartridge 5 sequentially and orderly fall onto the threads of the screw 6 from the sewing needle cartridge 5. After being sorted by the paddle 8, it is ensured that each sewing needle 14 is located on the thread of the screw 6. The lubricating oil dropped through the needle tip on the lubricating block 7 just makes the lubricating block 7 lubricate the screw 6.

[0041] Step 3: The mechanical gripper 10 moves towards the screw 6. The mechanical gripper 10 is energized to have magnetic suction, sucks the sewing needle 14 sent out from the screw 6, and then the mechanical gripper 10 moves towards the direction of the conveyor belt 1. When the mechanical gripper 10 moves above the conveyor belt 1 and is close to the conveyor belt 1, the power is cut off, and the mechanical gripper 10 loses magnetism, and the sewing needle 14 falls from the mechanical gripper 10 onto the substrate.

[0042] Step 4: The conveyor belt 1 drives the substrate to continue running. The sealing layer feeding roll 9 releases the sealing layer, and the sealing layer passes through the flattening roller to press the sealing layer on the sewing needle 14 of the substrate. Before reaching the sealing structure, the substrate and the sealing layer always remain in contact, facilitating the subsequent sealing structure to package and seal the substrate and the sealing layer.

[0043] Step 5: When the conveyor belt 1 transports the substrate and the sealing layer below the sealing structure, the sealing surface 11 of the sealing structure presses downwards. Since the rectangular frame of the sealing surface 11 is a heating plate, the heating plate adhesively bonds the sealing layer and the substrate together at high temperature, and the sewing needle 14 is encapsulated between the sealing layer and the substrate;

[0044] Step 6: The conveyor belt 1 transports the packaged bag with the sealing completed below the cutting structure, and the cutting knife 12 of the cutting structure cuts the packaged bag between the sewing needles 14 in the direction of the conveyor belt 1. Finally, the packaged bag with the sewing needle 14 falls into the collection bucket from the blanking port 13, which is convenient for workers to transport.

The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments.
