Description

Technical Field

[0001] The invention mainly relates to the field of small package empty package detection, and specifically relates to a deoxidizer packaging quality detection device and a detection method. Background Art

[0002] Deoxidizer is an additive that can absorb oxygen and slow down the oxidation of food. Packaging it together with food can extend the shelf life of food and prevent it from premature oxidation and deterioration.

[0003] In the process of food packaging, it is necessary to use unloading equipment to progressively convey the rolled deoxidizer, cut the deoxidizer and put it into the food packaging in single packages. Therefore, in the production process of the deoxidizer, it is necessary to maintain the continuity of the deoxidizer packaging.

[0004] In the production process of deoxidizer, the deoxidizer completes continuous production through continuous feeding and three-side heat sealing. Then the deoxidizer is rolled and wound on the reel, and finally becomes a tray of finished products and is transported to food packaging companies for use. However, in the packaging process, due to the agglomeration of the deoxidizer itself, the material blocking problem or the transportation failure of the equipment, the deoxidizer packaging may be empty, the deoxidizer dosage may be insufficient, and other problems may occur. These insufficiently packaged deoxidizers are defective products and need to be discovered and removed in time. Otherwise, once they are transported to food companies, they will cause food safety problems due to the failure of the deoxidizer.

[0005] Unlike deoxidizers that are sold after slitting, deoxidizers wound on a turntable cannot be directly removed after defective products are found. The current method of handling defective deoxidizers wound on a turntable is to shut down the packaging equipment in time once defective products are found, and let the staff determine whether the defective products affect the use. If the defective products cannot be used, they are manually intercepted and the turntable is replaced. If the deoxidizer on the turntable is about to be full, it can be directly sent to the downstream for use. If the gap is large, it is sent to the cutting process to be split into individual small packages. Therefore, in the production process of the deoxidizer, it is necessary to strictly control the defective rate of the deoxidizer. Once an empty package occurs, the handling is extremely cumbersome, which seriously affects the production efficiency of the deoxidizer. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a deoxidizer packaging quality detection device and detection method, which can quickly realize the packaging quality detection of the deoxidizer and timely process it, and complete the removal of defective deoxidizer products without stopping the machine, thereby ensuring the processing efficiency of the deoxidizer.

A handling mechanism is arranged between the buffer zones, the handling mechanism comprising a transverse slide rail and a transverse screw drive mechanism arranged on the conveying frame, a mounting seat is arranged on the transverse slide rail, the transverse screw drive mechanism is used to drive the mounting seat to slide back and forth along the transverse slide rail, a fixed fixture and a sliding fixture are arranged on the mounting seat, a sliding table cylinder for driving the sliding fixture to approach or move away from the fixed fixture is arranged on the mounting seat, a pneumatic shear is arranged on the fixed fixture to rotate toward one side of the sliding fixture, the pneumatic shear has two groups of shearing knives arranged symmetrically, a swing motor for driving the pneumatic shear to swing is arranged on the fixed fixture, the swing motor is used to drive the pneumatic shear to swing to both sides of the deoxidizer to complete shearing, a heat sealing mechanism is arranged between the fixed fixture and the sliding fixture, the heat sealing mechanism comprises a pair of heat sealing sheets arranged up and down, the two heat sealing sheets are driven by a double-headed cylinder to approach or move away from each other, a clamping mechanism is arranged between the visual recognition platform and the front buffer zone, the clamping mechanism is used to clamp and limit the continuously conveyed deoxidizer.

[0009] The front lifting drive mechanism includes a front screw drive mechanism and a front lifting slide rail, a front lifting platform is slidably arranged on the front lifting slide rail, and the front buffer roller is rotatably arranged on the front lifting platform; the rear lifting drive mechanism includes a rear screw drive mechanism and a rear lifting slide rail, a rear lifting platform is slidably arranged on the rear lifting slide rail, and the rear buffer roller is rotatably arranged on the rear lifting platform.

[0010] The front fixed rollers have two pairs, the front buffer roller has one, the front buffer roller is located between the two front fixed rollers, and the front lifting drive mechanism is used to drive the front buffer rollers to rise or fall; the rear fixed rollers have two pairs, the rear buffer roller has one, the rear buffer roller is located between the two rear fixed rollers, and the rear lifting drive mechanism is used to drive the rear buffer rollers to rise or fall.

[0011] The fixed fixture and the sliding fixture both adopt two-claw pneumatic fixtures.

[0012] An air-cooling blow pipe is arranged at the bottom of the mounting seat, and the air-cooling blow pipe is connected to the fan.

[0013] The shearing knife includes a fixed blade and a shearing blade. A shearing bracket is fixedly arranged at the bottom of the pneumatic shears. The fixed blades are symmetrically arranged on both sides of the shearing bracket. The two shearing blades are arranged at both ends of the cylinder piston rod of the pneumatic shears. When the pneumatic shears are swung to a vertical state, the deoxidizer is located between the fixed blade and the shearing blade. When the pneumatic shears are swung to a horizontal state, the fixed blade and the shearing blade are separated from the deoxidizer.

[0014] A method for detecting the packaging quality of a deoxidizer is provided, wherein the packaging quality of the deoxidizer is detected using any of the quality detection devices described above, and the specific steps are as follows:

[0015] S1: The deoxidizer is continuously packaged and cached in the rear buffer. When the rear buffer is used for deoxidizer caching, the turntable mechanism does not reel in the deoxidizer. When the buffer deoxidizer of the rear buffer roller reaches the maximum capacity, the rear buffer roller quickly releases the cache, and the turntable mechanism rotates to complete the reeling of the deoxidizer.

[0016] S2: The deoxidizers that continuously pass through the visual recognition table are inspected by a visual recognition camera. The light-transmitting area in each deoxidizer package is analyzed to determine whether the deoxidizer packaging quantity is sufficient. If the light-transmitting area exceeds the standard, the deoxidizer package is unqualified.

[0017] S3: If the deoxidizer is unqualified, the clamping mechanism stops the continuously conveyed deoxidizer, and the front buffer roller of the front buffer acts to buffer the conveyed deoxidizer. Then the mounting seat is driven by the horizontal screw drive mechanism to move the fixed fixture and the sliding fixture to the two sides of the unqualified deoxidizer.

[0018] S4: Then, the deoxidizer is clamped by a fixed clamp and a sliding clamp, and the unqualified deoxidizer is located between the fixed clamp and the sliding clamp. Then, the unqualified deoxidizer is cut off by a pneumatic shear, and the sliding clamp drives the joint at one end of the deoxidizer to approach the deoxidizer joint clamped by the fixed clamp, and then the two deoxidizer joints are heat-sealed and connected by a heat-sealing mechanism;

[0019] S5: After the deoxidizer is reconnected, the fixed clamp and the sliding clamp release the clamping of the deoxidizer, and then the sliding clamp is reset, the mounting seat is reset, and at the same time, the clamping mechanism releases the clamping of the deoxidizer, the front buffer roller releases the cached deoxidizer, and at the same time, the rear buffer roller synchronously stores the cached deoxidizer released by the front buffer roller.

[0020] Preferably, if the buffer stored in the rear buffer roller reaches an upper limit while the front buffer roller releases the buffer, the front buffer roller temporarily stops releasing the buffered deoxidizer until the turntable mechanism completes winding the deoxidizer buffered by the rear buffer roller, and the front buffer roller continues to release the buffered deoxidizer, and the rear buffer roller continues to buffer the deoxidizer released by the front buffer roller.

[0021] Preferably, in S4, the portion of the deoxidizer cut off by the pneumatic shears is smaller than the length of a single package of deoxidizer.

[0022] Preferably, the sliding clamp is located downstream of the deoxidizer delivery, and the fixed clamp is located upstream of the deoxidizer delivery. When the sliding clamp and the fixed clamp complete clamping of the deoxidizer, the clamping planes of the sliding clamp and the fixed clamp are misaligned.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The present invention adds an automatic detection visual recognition system in the production process of the deoxidizer, which can automatically detect the continuously conveyed deoxidizer and complete the detection of unqualified deoxidizers. After the detection is completed, the disposal mechanism can complete the removal of unqualified products and the continuation of disconnected deoxidizers to meet the continuity of the production of the whole tray of deoxidizer, ensure that the deoxidizer can always be produced in full trays, and avoid the subsequent cumbersome processing matters caused by empty packages or insufficient deoxidizers.

[0025] The present invention can solve the shutdown problem when dealing with defective products through the dual buffering setting of the front buffer and the rear buffer. Through the cache of the front buffer, the packaging equipment does not need to be shut down when dealing with defective products. The continuous deoxidizer produced during the process is all cached by the front buffer. It is only necessary to replace all the caches of the front buffer to the rear buffer after the defective products are removed. This structure solves the problem of needing to shut down the machine for processing once defective products are found, and improves the overall production efficiency.

[0026] The disposal mechanism of the present invention can automatically complete the cutting and removal of unqualified products and the reconnection of the two ends of the deoxidizer after disconnection. The whole process is completed automatically, and the traces of the deoxidizer after connection are not obvious, which will not affect the overall aesthetics. Through this structure, the hysteresis and instability of manual disposal are completely eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0036] like Figure 1-7As shown, a deoxidizer packaging quality detection device described in the present invention includes a powder packaging machine, which is used to complete the packaging of the deoxidizer. The powder packaging machine adopts an automated slow deoxidizer packaging machine, which can realize automatic loading, weighing and unloading, three-side packaging and other operations of the deoxidizer. A conveyor frame 1 is set on one side of the powder packaging machine, and a plurality of pairs of conveying rollers 11 are installed between the conveyor frame 1 and the powder packaging machine. The conveying rollers 11 are used for conveying, reversing and carrying the continuously packaged deoxidizer, and conveying the deoxidizer to the subsequent detection, disposal and winding process. Specifically, at least half of the conveying rollers 11 are powered, and the speed of the powered conveying rollers 11 is consistent. The conveying rollers 11 are driven by a transmission mechanism driven by a driving motor, or are directly driven by multiple driving motors alone, thereby ensuring the continuity of the deoxidizer conveying.

[0037] The front side of the conveyor frame 1 is a front buffer zone 2, which is used to cache the continuously transported deoxidizer. Specifically, the front buffer zone 2 includes a plurality of front fixed rollers 21 and at least one front buffer roller 22, and a front lifting drive mechanism 31 for driving the front buffer roller 22 to rise and fall is arranged at the rear side of the front buffer zone 2. In this embodiment, there are two pairs of front fixed rollers 21, and one front buffer roller 22. The front buffer roller 22 is located between the two front fixed rollers 21, and each pair of front buffer rollers 22 is arranged in an upper and lower position relationship, and the deoxidizer passes between the two front buffer rollers 22. The front buffer roller 22 is driven to rise or fall by the front lifting drive mechanism 31, so that the front buffer roller 22 can be relatively far away from the front fixed roller, thereby increasing the stroke of the continuously transported deoxidizer bypassing the three, thereby achieving the purpose of caching the deoxidizer. When caching, the front buffer roller 22 can be designed to rise or fall relative to the front fixed roller 21, and the selection is made according to the overall space of the equipment. In this embodiment, the front buffer roller 22 is a rising cache structure.

[0038] A visual recognition station 4 is horizontally arranged downstream of the front buffer zone 2. The visual recognition station 4 is made of semi-transparent material and has a built-in light source, so that the visual recognition station 4 can emit white light evenly. The continuously transported deoxidizer passes over the visual recognition station 4. Through the white light of the visual recognition station 4, the translucent area and the opaque area blocked by the deoxidizer particles can be displayed on the deoxidizer package. By analyzing the area of ​​the translucent area and the opaque area, it can be determined whether the deoxidizer package is filled with enough deoxidizer particles, thereby determining the quality of the deoxidizer package. A visual recognition camera 41 is installed above the visual recognition station 4. The visual recognition camera 41 is used to collect the translucent image of the deoxidizer, and to identify and analyze the image on the engineering machine. When the translucent area of ​​the deoxidizer package exceeds the standard, it is determined that the deoxidizer package is unqualified.

[0039] A rear buffer zone 5 is arranged downstream of the visual recognition station 4, and the rear buffer zone 5 is also used to cache the continuously transported deoxidizer, so as to facilitate the intermittent reeling of the deoxidizer by the subsequent turntable mechanism 7. The rear buffer zone 5 includes a plurality of rear fixed rollers 51 and at least one rear buffer roller 52, and a rear lifting drive mechanism 32 for driving the rear buffer roller 52 to rise and fall is arranged at the rear side of the rear buffer zone 5. Specifically, in this embodiment, there are two pairs of rear fixed rollers 51, and there is one rear buffer roller 52. The rear buffer roller 52 is located between the two pairs of rear fixed rollers 51, and a pair of rear fixed rollers 51 are arranged in an upper and lower position relationship, and the deoxidizer passes between the two rear fixed rollers 51 on the same side. The rear lifting drive mechanism 32 is used to drive the rear buffer roller 52 to rise or fall. Consistent with the structure of the front buffer zone 2, in this embodiment, the rear buffer roller 52 is away from the rear fixed roller 51 when it descends downward, thereby increasing the stroke between the rear fixed roller 51 and the rear fixed roller 51, so as to achieve the purpose of deoxidizer caching.

[0040] A turntable mechanism 7 is provided downstream of the rear buffer zone 5, and the turntable mechanism 7 is used to reel in the deoxidizer. The turntable mechanism 7 is intermittent in rotating and reeling in the deoxidizer. When the rear buffer zone 5 caches the deoxidizer to the maximum capacity, the turntable mechanism 7 starts to reel in the deoxidizer, and at the same time cooperates with the rear buffer roller 52 to quickly approach the rear fixed roller 51 to quickly release the cache. This structure can ensure the rapid reeling of the deoxidizer by the turntable mechanism 7, and solve the problem of inconsistency between the reeling action of the turntable mechanism 7 and the conveying rate of the deoxidizer. A torque sensor is installed on the turntable mechanism 7. When the cached deoxidizer is reeled in, the torque increases, thereby controlling the turntable mechanism 7 to stop the reeling action to avoid breaking the continuously conveyed deoxidizer.

[0041] More specifically, in this embodiment, the front lifting drive mechanism 31 of the front buffer 2 and the rear lifting drive mechanism 32 of the rear buffer 5 both adopt a lead screw drive device, so as to stably drive the front buffer roller 22 and the rear buffer roller 52. The front lifting drive mechanism 31 includes a front lead screw drive mechanism 311 and a front lifting slide rail 312, on which a front lifting platform 313 is slidably arranged, and the front buffer roller 22 is rotatably arranged on the front lifting platform 313. The front lead screw drive mechanism 311 is a lead screw driven by a stepper motor, and a lead screw nut matched with the lead screw and a sliding pair matched with the front lifting slide rail 312 are installed at the rear side of the front lifting platform 313. In this embodiment, the front lifting slide rail 312 has a pair, and the lead screw is installed between the two front lifting slide rails 312, so that the front lifting platform 313 can be driven to perform a stable lifting action under the restriction of the front lifting slide rail 312 through the drive of the lead screw. The rear lifting drive mechanism 32 includes a rear lead screw drive mechanism 321 and a rear lifting rail 322. A rear lifting platform 323 is slidably arranged on the rear lifting rail 322, and a rear buffer roller 52 is rotatably arranged on the rear lifting platform 323. The rear lead screw drive mechanism 321 is also a lead screw driven by a stepper motor. The rear side of the rear lifting platform 323 is installed with a lead screw nut matched with the lead screw on this side and a sliding pair matched with the rear lifting rail 322. In this embodiment, the rear lifting rail 322 also has a pair. The lead screw of the rear lead screw drive mechanism 321 is installed between the two rear lifting rails 322, so that the rear lifting platform 323 is driven by the lead screw to perform a stable lifting action under the restriction of the rear lifting rail 322.

[0042] A disposal mechanism 6 is provided between the visual recognition platform 4 and the post-buffer zone 5, and the disposal mechanism 6 is used to process and remove the detected defective products.

[0043] The disposal mechanism 6 is a core component of the present invention, and is used to dispose of unqualified deoxidizers, so that after the unqualified deoxidizers are removed, the cut deoxidizers are reconnected to facilitate the automatic feeding of downstream manufacturers. The disposal mechanism 6 includes a displacement component, a clamping component, a shearing component, and a heat sealing component.

[0044] Displacement Components:

[0045] The displacement assembly is a transverse slide rail 61 and a transverse screw drive mechanism 62 arranged on the conveyor frame 1. The transverse slide rail 61 is arranged horizontally. In order to maintain stability, a pair of transverse slide rails 61 are arranged, and the transverse screw drive mechanism 62 is installed between the two transverse slide rails 61. A mounting seat 63 is slidably arranged on the transverse slide rail 61, and the transverse screw drive mechanism 62 is used to drive the mounting seat 63 to slide back and forth along the transverse slide rail 61. The transverse screw drive mechanism 62 is driven by a servo motor, so that the mounting seat 63 thereon can be driven to operate stably, ensuring that the mounting seat 63 can accurately stay at any position, so that defective products can be accurately removed.

[0046] Clamping components:

[0047] The clamping assembly includes a fixed clamp 64 and a sliding clamp 65, and the fixed clamp 64 and the sliding clamp 65 are respectively installed on the left and right sides of the mounting seat 63. The sliding clamp 65 is located downstream of the deoxidizer delivery, and the fixed clamp 64 is located upstream of the deoxidizer delivery. A slide cylinder 66 is provided on the mounting seat 63 for driving the sliding clamp 65 to approach or move away from the fixed clamp 64. Specifically, a mounting groove is provided in the middle of the mounting seat 63, and the slide cylinder 66 is installed in the mounting groove. The fixed clamp 64 is installed across the mounting groove, and the sliding clamp 65 is installed on the sliding pair of the slide cylinder 66. The sliding pair of the slide cylinder 66 is installed at a position slightly higher than the mounting groove, so as not to interfere with the normal sliding of the slide cylinder 66. Through the contraction action of the slide cylinder 66, the sliding clamp 65 can be driven to move toward the fixed clamp 64, thereby completing the docking of the two ends of the deoxidizer. The fixed clamp 64 and the sliding clamp 65 are both pneumatic two-claw clamps. Through the clamping action of the fixed clamp 64 and the sliding clamp 65, the two ends of the deoxidizer can be clamped. More specifically, in the normal packaging and transportation link of the deoxidizer, the deoxidizer passes through the opened fixed clamp 64 and the sliding clamp 65. When it is necessary to deal with the unqualified deoxidizer, the mounting seat 63 is driven by the horizontal screw drive mechanism 62 to move to the unqualified deoxidizer. During the movement, only the bottom clamps of the fixed clamp 64 and the sliding clamp 65 are in contact with the bottom surface of the continuous deoxidizer. After the fixed clamp 64 and the sliding clamp 65 come to both sides of the unqualified deoxidizer, the fixed clamp 64 and the sliding clamp 65 simultaneously complete the clamping of the two ends of the deoxidizer. More specifically, the distance between the fixed clamp 64 and the sliding clamp 65 is slightly smaller than the single package length of the deoxidizer, so that a longer size is left after the shearing is completed, so that the two ends of the sheared deoxidizer can be fixed by dislocation docking and heat sealing.

[0048] More specifically, in order to ensure that the deoxidizer can be perfectly docked after shearing, in this embodiment, after the sliding clamp 65 and the fixed clamp 64 complete the clamping of the deoxidizer, the clamping planes of the sliding clamp 65 and the fixed clamp 64 are misaligned, thereby driving the clamped end of the deoxidizer to overlap and dock with the front end of the deoxidizer, which is more convenient for heat sealing and reconnection of the deoxidizer.

[0049] Cutting components:

[0050] The shearing assembly adopts a pneumatic shear 9, which is arranged between the fixed clamp 64 and the sliding clamp 65. The pneumatic shear 9 has two sets of shearing knives 92 arranged symmetrically, and the distance between the two sets of shearing knives 92 is slightly less than the length of a single package of deoxidizer, so that the deoxidizer portion cut by the pneumatic shear 9 is less than the length of a single package of deoxidizer. This structure allows the pneumatic shear 9 to reserve enough length to facilitate the heat-sealing connection of the deoxidizers at both ends after removing the unqualified deoxidizer. Specifically, the two sets of shearing knives 92 each include a fixed blade 93 and a shearing blade 94, wherein the fixed blade 93 is located at the bottom, and the bottom of the pneumatic shear 9 has a cutting bracket 95, and the fixed blades 93 are symmetrically arranged at the bottom of both sides of the cutting bracket 95. The cylinder of the pneumatic shear 9 is installed on the cutting bracket 95, and the piston rod of the cylinder is arranged downward. The two shearing blades 94 are arranged at both ends of the piston rod of the cylinder of the pneumatic shear 9. Through the extension action of the cylinder, the shearing blades 94 can be pushed downward to cooperate with the fixed blades 93 to complete the cutting of the deoxidizer. Since the present invention needs to shorten the distance between the sliding fixture 65 and the fixed fixture 64 by displacement after the deoxidizer is cut to complete the heat sealing operation of the deoxidizer, the pneumatic shear 9 needs to have a displacement mechanism to disengage the position between the sliding fixture 65 and the fixed fixture 64 after the shearing action is completed. The displacement mechanism of the pneumatic shear 9 can be completed by an extension mechanism and a swing mechanism. In order to reduce the installation space and make the installation distance between the mounting seat 63 and the clamping assembly not too large, the present embodiment preferably uses a swing mechanism. After the pneumatic shear 9 completes the shearing action, the pneumatic shear 9 flips to the top so that the linear displacement of the sliding fixture 65 does not interfere with the pneumatic shear 9.

[0051] Specifically, the pneumatic shears 9 are installed on the fixed fixture 64 on the side facing the sliding fixture 65. The cutting bracket 95 of the pneumatic shears 9 is hinged to the top bracket of the mounting seat 63. The mounting seat 63 is installed with a swing motor 91 for driving the pneumatic shears 9 to swing. The output shaft of the swing motor 91 is connected to the rotating shaft of the cutting bracket 95. The pneumatic shears 9 can be driven to swing as a whole by the drive of the swing motor 91, so as to realize the swing of the pneumatic shears 9 between the fixed fixture 64 and the sliding fixture 65 and the swing above the fixed fixture 64. When the pneumatic shears 9 swing to a vertical state, the deoxidizer is located between the fixed blade 93 and the shearing blade 94. Then, the shearing blade 94 of the pneumatic shears 9 and the fixed blade 93 interlace to complete the automatic shearing of the deoxidizer. When the pneumatic shears 9 swings to a horizontal state, the pneumatic shears 9 has swung to the top of the fixed clamp 64. At this time, the fixed blade 93 and the shearing blade 94 are separated from the deoxidizer, exposing the space between the fixed clamp 64 and the sliding clamp 65, making it easier for the sliding clamp 65 to approach the fixed clamp 64 without interfering with the heat-sealed reconnection of the sheared deoxidizer.

[0052] Heat sealing components:

[0053] A heat sealing mechanism 8 is installed between the fixed fixture 64 and the sliding fixture 65. The heat sealing mechanism 8 is installed on the slide cylinder inside the sliding fixture 65. The heat sealing mechanism 8 and the sliding fixture 65 are driven by the slide cylinder 66 to move toward the fixed fixture 64. The heat sealing mechanism 8 includes an extension cylinder 82 and a clamping cylinder 83. The extension cylinder 82 is fixedly installed on the sliding pair of the slide cylinder. The clamping cylinder 83 is a double-headed cylinder, and the clamping cylinder 83 is installed at the front end of the piston rod of the extension cylinder 82. A pair of heat sealing sheets 81 are arranged up and down on the clamping cylinder 83, and the two heat sealing sheets 81 can be driven to move toward or oppositely by the clamping cylinder 83. The heat sealing sheet 81 is electrically heated and has a temperature control device. The heat sealing sheet 81 is a long strip structure, which can heat and fuse the plastic-sealed packaging between the two deoxidizers and reconnect them into a continuous state through heat. Specifically, the width of the two heat-sealing sheets 81 does not exceed the sealing width of the continuously produced deoxidizer during the automatic packaging process. The two heat-sealing sheets 81 are driven by a double-headed cylinder to move closer to or farther away from each other. When the two heat-sealing sheets 81 are close to each other, the two ends of the deoxidizer overlapped by the clamping of the fixed clamp 64 and the sliding clamp 65 are heat-sealed, and the period is 1-1.5s. After the heat sealing is completed, the two heat-sealing sheets 81 move away from each other again, and then the heat-sealing sheets are contracted after the stretching cylinder 82 is contracted, so as not to interfere with the subsequent pneumatic shears 9. Specifically, the two heat-sealing sheets need to be powered on at all times for preheating, and the two heat-sealing sheets are controlled by a temperature control device to be maintained at 160±10 degrees to ensure that the heat-sealing connection operation can be completed at any time. The spacing between the two heat-sealing sheets should be greater than 5cm to prevent the hanging deoxidizer from being scalded by the temperature.

[0054] More specifically, a clamping mechanism 33 is provided between the visual recognition station 4 and the front buffer zone 2, and the clamping mechanism 33 is used to clamp and limit the continuously transported deoxidizer. The clamping mechanism 33 is a two-claw clamp driven by a double-headed cylinder. The continuously transported deoxidizer passes through the two-claw clamp. The two-claw clamp can be driven by the double-headed cylinder to clamp the deoxidizer, thereby fixing the transport of the deoxidizer, so that when the mounting seat 63 is used to position the unqualified deoxidizer later, misalignment can be avoided, so that the unqualified deoxidizer can be removed more accurately.

[0055] More specifically, an air-cooling blowpipe 67 is provided at the bottom of the mounting seat 63, and the air-cooling blowpipe 67 is connected to a blower. The air outlet of the air-cooling blowpipe 67 faces the direction of the deoxidizer to be re-heat-sealed and connected. After the heat sealing is completed, the air-cooling blowpipe 67 blows out soft air to accelerate the solidification, so that the two sections of deoxidizer can be connected as a whole as soon as possible, so as to withstand the pulling force in the subsequent winding operation.

[0056] A method for detecting the packaging quality of a deoxidizer is provided, wherein the packaging quality of the deoxidizer is detected using the quality detection device provided above, and the specific steps are as follows:

[0057] The deoxidizer is automatically loaded and continuously packaged on the granular powder packaging machine. The packaged deoxidizer is continuously discharged and progressively conveyed to the turntable mechanism 7 at the end for winding. The deoxidizer is first cached in the rear buffer 5. When the rear buffer 5 is used to cache the deoxidizer, the turntable mechanism 7 is not started. At this time, the turntable does not wind up the deoxidizer. When the buffer deoxidizer of the rear buffer roller 52 reaches the maximum capacity, the rear buffer roller 52 quickly releases the cache, and the turntable mechanism 7 rotates to complete the winding of the deoxidizer. The rear buffer 5 is set to balance the rotation speed of the turntable mechanism 7. Since the speed of the deoxidizer is consistent and cannot be changed during packaging, and the turntable mechanism 7 cannot change speed according to the packaging speed of the deoxidizer, the rear buffer 5 is set so that the turntable mechanism 7 can complete the winding of the deoxidizer at its own speed at one time to ensure the winding effect.

[0058] During the transportation process, the deoxidizer passes through the middle visual recognition table 4. The visual recognition camera 41 detects the deoxidizers that continuously pass through the visual recognition table 4, and analyzes the light-transmitting area in each deoxidizer package to determine whether the deoxidizer packaging quantity is sufficient. If the light-transmitting area exceeds the standard, the deoxidizer package is unqualified.

[0059] If the qualified deoxidizer passes through, the system will not make any action feedback, but if the unqualified deoxidizer passes through, the system will react. The clamping mechanism 33 acts to stop the continuously transported deoxidizer, and at the same time, the front buffer roller 22 of the front buffer 2 acts to buffer the transported deoxidizer. Then the mounting seat 63 is driven by the horizontal screw drive mechanism 62, and with the data support of the visual recognition camera 41, the fixed clamp 64 and the sliding clamp 65 are moved to the two sides of the unqualified deoxidizer, and then the fixed clamp 64 and the sliding clamp 65 are used to clamp the deoxidizer, and the unqualified deoxidizer is located between the fixed clamp 64 and the sliding clamp 65. Then, the unqualified deoxidizer is cut off by the pneumatic shears 9. After the deoxidizer is cut off, the pneumatic shears 9 is flipped over to the top of the fixed clamp 64 under the drive of the swing motor 91, and the sliding clamp 65 drives the joint at one end of the deoxidizer to approach the deoxidizer joint clamped by the fixed clamp 64, and finally the two joints are stacked, and then the two deoxidizer joints are heat-sealed and connected using the heat sealing mechanism 8.

[0060] After the deoxidizer is reconnected, the fixed clamp 64 and the sliding clamp 65 release the clamping of the deoxidizer, and then the sliding clamp 65 is reset, the mounting seat 63 is reset, and the pneumatic shear 9 is turned downward under the drive of the swing motor 91, so that the deoxidizer passes between the fixed blade 93 and the shear blade 94. At the same time, the clamping mechanism 33 releases the clamping of the deoxidizer, and the front buffer roller 22 releases the cached deoxidizer. At the same time, the rear buffer roller 52 synchronously stores the cached deoxidizer released by the front buffer roller 22. The caching and release rates of the deoxidizer by the front buffer roller 22 are consistent with the packaging rate of the deoxidizer, the caching rate of the deoxidizer by the rear buffer roller 52 is consistent with the packaging rate of the deoxidizer, and the release rate of the deoxidizer by the rear buffer roller 52 is much greater than the packaging rate of the deoxidizer, and is slightly faster than the maximum winding rate of the turntable mechanism 7. During this action, if the buffer stored in the rear buffer roller 52 reaches the upper limit while the front buffer roller 22 releases the buffer, the front buffer roller 22 temporarily stops releasing the buffered deoxidizer until the turntable mechanism 7 completes winding of the deoxidizer buffered by the rear buffer roller 52, and then the front buffer roller 22 continues to release the buffered deoxidizer, and the rear buffer roller 52 continues to buffer the deoxidizer released by the front buffer roller 22.
