A material guiding channel 2 for material feeding is provided at the front end of the mounting base, a magnetic button dropping port is provided at the rear side of the material guiding channel, and a magnetic button pushing unit for pushing the magnetic button 31 into the material guiding channel is installed at the top of the mounting base;

[0031] The encapsulation unit includes a plastic film conveying mechanism and a plastic bag forming mechanism. A plastic film conveying mechanism is provided at the front end of the material guiding channel, and a plastic bag forming mechanism is provided at the lower part of the material guiding channel.

[0032] The described magnetic button pushing unit includes a base 30, a material pushing cylinder 21, a push plate 22, a base plate of the tube seat 26, a magnetic button storage tube 24, a reader-writer 28 and a flipping cylinder 29. A base is installed on the top surface of the installation foundation. A push plate driven by the material pushing cylinder is installed at the rear end of the upper surface of the base. A base plate of the tube seat is arranged at the front end of the upper surface of the base. A fixed tube sleeve 25 is arranged on the base plate of the tube seat. The magnetic button storage tube is sleeved in the fixed tube sleeve. The magnetic button storage tube is an acrylic tube. A tube cap is arranged at the top of the magnetic button storage tube. Openings for the push plate to stretch are arranged at the front and rear ends of the bottom of the magnetic button storage tube and the fixed tube sleeve. A reader-writer flush with the upper surface of the base plate of the tube seat is arranged at the front end of the base. The reader-writer is hinged to the flipping cylinder through a mounting bracket. The flipping cylinder is installed on the base. Part of the flipping cylinder is arranged in a magnetic button dropping opening provided with a material guiding channel so that when the flipping cylinder flips, the magnetic buttons can fall into a plastic bag containing materials along the material guiding channel.

[0033] To achieve stable pushing of the magnetic buttons, the front end face of the push plate is an arc-shaped groove structure adapted to the radian of the magnetic buttons. To prevent manual replacement of the magnetic buttons, a protective cover 27 covering the base plate of the tube seat and the reader-writer is arranged at the front end of the magnetic button storage tube.

[0034] The magnetic button pushing unit further includes a lower limit alarm 23. A lower limit alarm is arranged on the tube wall of the magnetic button placement tube. The lower limit alarm can be a laser switch. When the number of magnetic buttons reaches the set lower limit value, the lower limit alarm sends a signal to the control system to replenish the magnetic buttons in time to ensure the normal progress of the magnetic button pushing work.

[0035] The working principle of the magnetic button pushing unit is as follows:

[0036] The material pushing cylinder drives the push plate to act. The push plate pushes the magnetic button at the bottom of the magnetic button storage tube forward until it is pushed onto the reader-writer. The reader-writer reads the data of the magnetic button and sends it to the CPU. The CPU completes the binding of the magnetic button and the information of the material to be sampled. Then, the flipping cylinder flips to realize the feeding of the magnetic buttons. After the push plate pushes the magnetic button onto the reader-writer, the push plate retracts and waits for the next round of magnetic button pushing work.

[0037] The plastic film conveying mechanism of the encapsulation unit includes a film reel stand 4, a film roller mounting frame 5, a film pulling motor 7, a magnetic film pulling roller 18, a slide bar 20 and a guide bar 3. A film reel stand is installed at the front end of the installation base, a film roller mounting frame is installed on the film reel stand, a plastic film roller 17 is installed on the film roller mounting frame, two horizontally installed plates 8 symmetrically arranged inside and outside are installed at the front end of the film reel stand, a driving film pulling rod and a driven film pulling rod 19 arranged opposite to each other front and back are respectively installed between the two horizontally installed plates, magnetic film pulling rollers are installed on both the driving film pulling rod and the driven film pulling rod. The magnetic film pulling roller is a magnet roller wrapped with a rubber pad on the outside, and the plastic film 6 passing through is flattened and unfolded by the adsorption of the front and back magnets; the driving film pulling rod is driven by the film pulling motor. Vertical installation plates 10 are arranged at the lower parts of the horizontal installation plates, vertical long holes 9 are arranged on the vertical installation plates, the slide bar is slidably installed in the two vertical long holes, a film induction sensor is installed at the bottom of one of the vertical long holes, and a guide bar is installed at the rear end of the film reel stand.

[0038] During operation, the bag pulling servo motor drives the bag pulling pressure wheel group to pull the bag downward, the plastic film will lift the slide bar, so that the slide bar can disengage from the film induction sensor. When the film induction sensor cannot sense the slide bar, the signal is reversed, triggering the film pulling motor to rotate and release the film. The linear speed of the film pulling motor is faster than that of the bag pulling pressure wheel group. When the film pulling motor works, the film will immediately be in excess, causing the slide bar to move downward. After the film induction sensor senses the slide bar, it triggers the film pulling motor to stop working, achieving the balance of film pulling and releasing.

[0039] The film winding method is as follows: Pull out the end of the plastic film on the plastic film roller, first pass through between the driving film pulling rod and the driven film pulling rod, then bypass from below the slide bar, and then wind out from above the guide bar.

[0040] The plastic bag forming mechanism of the encapsulation unit includes a former 14, a bag pulling pressure wheel group 12, a vertical sealing heating block 13 and a transverse sealing mechanism 16. A former is butted at the bottom of the material guiding channel, a bag pulling pressure wheel group abutted against the former is arranged on the installation base, the pressure wheels on the bag pulling pressure wheel group are driven to rotate by a bag pulling servo motor, and the bag pulling action is realized under the rotation of the pressure wheels.

[0041] The former is a sleeve structure, and the sleeve includes a conical section and a vertical section arranged up and down. The conical section is butted at the bottom of the material guiding channel, and the vertical section is opposite to the film pulling roller group and the vertical sealing heating block.

[0042] The transverse sealing mechanism includes a mounting shell, a fixed clamping block 36, a movable clamping block 32, a fixed transverse sealing heating block 35, a movable transverse sealing heating block 33 and a transverse packaging cylinder. The mounting shell is mounted on the mounting base. The fixed clamping block and the fixed transverse sealing heating block are fixedly mounted in the front end of the mounting shell. The transverse packaging cylinder for driving the movable clamping block and the movable transverse sealing heating block to extend and retract is mounted in the rear mounting base of the mounting shell. The fixed clamping block and the fixed transverse sealing heating block are respectively arranged opposite to the movable clamping block and the movable transverse sealing heating block. Rubber pads 34 are arranged on the end faces of the fixed clamping block and the movable clamping block. A blade is arranged in the end face of the fixed transverse sealing heating block, and the blade edge portion of the blade extends out from the end face of the fixed transverse sealing heating block. A cutting groove opposite to the blade is arranged on the end face of the movable transverse sealing heating block. When the movable transverse sealing heating block is connected to the fixed transverse sealing heating block, the protruding blade is used to cut the plastic bag. The vertical sealing heating block and the transverse sealing mechanism are both thermoplastic sealing technologies in the prior art, and the working principle of the heat sealing part will not be repeated here.

[0043] The packaging unit also includes a negative pressure vacuum mechanism, which includes a negative pressure fan and an exhaust pipe 15. A negative pressure fan is installed in the installation base, and a three-way pipe is connected to the air suction port of the negative pressure fan.
