Description

Technical Field

[0001] The invention relates to the technical field of quick-freezing production equipment, and in particular to a detection and conveying device for a duck blood quick-freezing production line. Background Art

[0002] The food quick-frozen packaging production line is a device that can quickly freeze food that needs to be frozen for storage and transportation. It is easy to use and can continuously transport food and quickly freeze it, making it convenient for staff to handle.

[0003] Chinese patent number CN217779910U discloses a food tunnel quick-freezing packaging production line, whose structure includes a machine body, an exhaust port, a baffle, a conveying block, a distribution box, and a support frame. A food tunnel quick-freezing packaging production line transports food through a conveyor belt on the machine body, so that the food is frozen and conveyed out in the freezing tunnel inside the machine body. When it is necessary to clean the conveyor belt on the conveying block, a water pipe can be inserted into the conveying pipe on the outer shell, and the elastic sealing block can be pushed open to allow liquid to enter the inner part of the outer shell, causing an impact on the partition net, so that the partition net moves vertically upward under the guidance of the sliding rod, so that the partition net sprays out part of the detergent and drives the cleaning brush to contact the conveyor belt at the same time. At this time, the conveyor belt can be driven to run for cleaning, so that the conveyor belt can be better cleaned when the equipment is in use to avoid the residual liquid on it from breeding bacteria and causing pollution.

[0004] Although the above device can quickly freeze food safely and effectively, in order to improve the efficiency of quick freezing of food in actual quick freezing production, the staff generally adjusts the conveying speed of the conveyor belt according to the freezing speed of the food to ensure the quick freezing production efficiency. However, for example, duck blood products need to add an appropriate amount of regulator each time during production. After the regulator and duck blood are mixed, it is difficult to accurately control the freezing average speed of the regulator and duck blood, which will cause some duck blood to freeze slowly. As a result, the conveyor belt can only be adjusted according to the duck blood with the lowest freezing speed, affecting production efficiency. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes accurate detection of the freezing state of duck blood products by integrating a continuous freezing measuring device. The one-to-one correspondence between the press detector and the limit placement slot ensures that each duck blood product can be independently tested. This design not only improves the accuracy of the detection, but also enables the classification and unloading device to adjust the unloading path in real time according to the test results, and effectively distinguish qualified duck blood products from unqualified duck blood products. This precise detection and classification mechanism avoids the decline in overall production efficiency due to uneven freezing, while ensuring that the freezing quality of the final product meets the standard requirements.

[0018] 2. In the production process of duck blood products, the addition of regulators often affects the freezing speed, causing some duck blood products to freeze more slowly. Traditional methods usually adopt the strategy of reducing the conveyor belt speed to ensure that all duck blood products can be fully frozen, but this will seriously affect production efficiency. This equipment monitors the freezing state of duck blood products in real time through a continuous freezing measurement device, and flexibly adjusts the classification and unloading path according to the test results, thereby effectively dealing with the problem of uneven freezing caused by regulators. This flexibility not only improves the adaptability of the production line, but also ensures a steady increase in production efficiency.

[0019] 3. For unqualified duck blood products, the present invention transports them back to the freezing area through the reflux conveying device for secondary freezing treatment. The setting of the reflux conveying device also provides convenience for the staff, allowing them to quickly perform secondary treatment on unqualified products, thereby ensuring the overall quality of the final product. This reflux mechanism works in conjunction with the continuous freezing measuring device and the classified unloading device to form an efficient and flexible quick-freezing production line, providing a strong guarantee for improving overall production efficiency.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figures 1 to 11As shown, a duck blood quick-freezing production line detection and conveying equipment includes a circulating quick-freezing detection device installed on the quick-freezing production line 1, and the circulating quick-freezing detection device includes a limit placement device 2, a continuous pressing freezing detection device, a classification unloading device 4 and a reflux conveying device 5; there are multiple limit placement devices 2, and they are evenly distributed on the quick-freezing production line 1 at equal intervals, and the limit placement device 2 is provided with multiple limit placement grooves 21; the continuous freezing detection device 3 is installed at the discharge end of the quick-freezing production line 1, and the continuous freezing detection device 3 is provided with multiple groups of pressing detectors, and the pressing detectors correspond to the limit placement grooves 21 one by one; the classification unloading device 4 is installed below the continuous freezing detection device 3, and the classification unloading device 4 is provided with multiple discharge ends, and the classification unloading device 4 is used for classification unloading; the reflux conveying device 5 is installed next to the classification unloading device 4, and the reflux conveying device 5 is used for recycling defective frozen products.

[0035] The limiting placement devices 2 are evenly distributed on the quick freezing production line 1 at equal intervals, and each limiting placement device 2 is provided with a plurality of limiting placement grooves 21 for limiting and supporting the packaged duck blood products 6. When the production line is started, the limiting placement device 2 moves synchronously with the production line, driving the duck blood products 6 to pass through the quick freezing area for quick freezing.

[0036] After quick freezing, the duck blood product 6 moves with the position limiting placement device 2 to the continuous freezing detection device 3. The continuous freezing detection device 3 is provided with a press detector corresponding to the position limiting placement slot 21, and the duck blood product 6 is pressed and detected in sequence to evaluate its freezing state. The press detector uses pressure sensing technology to accurately determine whether the duck blood product 6 has achieved the expected freezing effect.

[0037] According to the detection information provided by the continuous freezing detection device 3, the classification unloading device 4 makes corresponding adjustments. When the duck blood products 6 that have passed the test are moved to the classification unloading device 4, the classification unloading device 4 will transport the duck blood products 6 that have passed the test to the waiting area for subsequent use. For the duck blood products 6 that have failed the test, the classification unloading device 4 will transport them to the reflux conveying device 5.

[0038] The reflux conveying device 5 is located beside the classification unloading device 4, and is responsible for conveying the unqualified duck blood products 6 back to the freezing area. The staff can put the unqualified duck blood products 6 into the limiting placement device 2 again for secondary freezing treatment.

[0039] Through this process, the equipment not only achieves precise control of the quick-freezing efficiency of duck blood products 6, but also ensures the stability of the freezing quality. Through the coordinated work of the continuous freezing measuring device 3 and the classified unloading device 4, the problem of uneven freezing caused by the addition of regulators is effectively avoided, thereby improving the overall production efficiency. At the same time, the setting of the reflux conveying device 5 also facilitates the secondary processing of unqualified products, further improving the flexibility and efficiency of the production line.

[0040] See also Figures 1 to 3 As shown, the limiting placement grooves 21 of the limiting placement device 2 are evenly distributed at equal intervals, the side walls of the limiting placement grooves 21 are provided with multiple insertion openings 22, the bottom of the limiting placement device 2 is provided with a limiting installation groove 24, a plurality of insertion holes 23 are provided between the limiting installation groove 24 and the limiting placement groove 21, and a floating stripping mechanism 25 is installed inside the limiting installation groove 24.

[0041] The limiting placement grooves 21 on the limiting placement device 2 are evenly distributed at equal intervals, and the limiting placement grooves 21 are used to store and support the packaged duck blood products 6. The side walls of the limiting placement grooves 21 are designed with multiple insertion openings 22, and the insertion openings 22 are arranged to facilitate the detection end of the pressing detector in the continuous freezing detection device 3 to smoothly contact the duck blood product 6, so as to detect the frozen state.

[0042] The bottom of the limit placement tool 2 is provided with a limit installation groove 24, which is used to install the floating stripping mechanism 25. A plurality of insertion holes 23 are provided between the limit installation groove 24 and the limit placement groove 21, and the insertion holes 23 provide a channel for the working end of the floating stripping mechanism 25 to extend into the limit placement groove 21.

[0043] During the process of the duck blood product 6 passing through the quick freezing production line 1 for quick freezing, the floating stripping mechanism 25 remains stationary or moves according to a preset timing. When the duck blood product 6 has completed quick freezing and needs to be inspected, the working end of the floating stripping mechanism 25 will pass through the insertion hole 23 as needed and extend into the interior of the limiting placement groove 21. This causes the duck blood product 6 in the limiting placement groove 21 to move upward, so that the duck blood product 6 floats slightly and breaks away from direct contact with the limiting placement groove 21. This prevents adhesion between the frozen duck blood product 6 and the limiting placement device 2, ensuring that the duck blood product 6 can be smoothly separated from the limiting placement device 2, facilitating subsequent transportation and processing.

[0044] See also Figures 1 to 5 As shown, the floating stripping mechanism 25 includes a floating push plate 251 installed inside the limiting mounting groove 24, the floating push plate 251 is slidably connected to the limiting mounting groove 24, a plurality of pushing and resisting blocks 2511 are provided on the top of the floating push plate 251, a mounting guide column 252 is installed on the bottom of the floating push plate 251, the end of the mounting guide column 252 away from the floating push plate 251 extends downward through the limiting placement device 2, the end of the mounting guide column 252 away from the floating push plate 251 is also provided with a resisting ball 253, a reset spring 254 is installed between the mounting guide column 252 and the limiting placement device 2, the floating stripping mechanism 25 also includes a floating adjustment plate 255 installed on the quick-freezing production line 1, and the top of the floating adjustment plate 255 is provided with a floating wave surface.

[0045] The floating push plate 251 forms a sliding connection structure with the limiting mounting groove 24 to ensure that the floating push plate 251 can move up and down within a limited range. A plurality of push and contact blocks 2511 are arranged on the top of the floating push plate 251, and the push and contact blocks 2511 are used to directly act on the duck blood product 6 to achieve a floating effect. A mounting guide column 252 is installed at the bottom of the floating push plate 251, one end of the mounting guide column 252 is fixedly connected to the floating push plate 251, and the other end extends downward through the limiting placement device 2, and a contact ball 253 is arranged at the end of the mounting guide column 252. A reset spring 254 is also installed between the mounting guide column 252 and the limiting placement device 2, and the reset spring 254 is used to provide continuous downward pressure for the floating push plate 251 to ensure that it remains in a low position when there is no external force.

[0046] In addition, the floating stripping mechanism 25 further comprises a floating adjustment plate 255 installed on the quick-freezing production line 1 . The top of the floating adjustment plate 255 is designed with a floating wave surface for dynamically contacting the abutting ball 253 .

[0047] At the stage when the duck blood product 6 has completed quick freezing and needs to be inspected, the quick freezing production line 1 drives the limit placement device 2 to move above the floating adjustment plate 255. At this time, the resistance ball 253 at the bottom of the floating adjustment plate 255 begins to contact the top of the floating adjustment plate 255. Due to the action of the reset spring 254, the resistance ball 253 always remains in a downward pressure state. When the limit placement device 2 continues to move above the floating wave surface, the resistance ball 253 moves along the floating wave surface. The design of the floating wave surface allows the resistance ball 253 to float up and down during the movement, thereby driving the installation guide column 252 and the floating push plate 251 to move synchronously up and down in the limit installation groove 24.

[0048] As the floating push plate 251 moves up and down, the push and abutment block 2511 extends through the insertion hole 23 into the interior of the position limiting placement groove 21, exerting upward pressure on the duck blood product 6, causing it to float slightly and break away from direct contact with the position limiting placement groove 21. This effectively prevents the frozen duck blood product 6 from adhering to the position limiting placement device 2, ensuring that the duck blood product 6 can be smoothly separated from the position limiting placement device 2.

[0049] See also Figure 1 , Figure 6 and Figure 7 As shown, the continuous freezing measuring device 3 includes a lifting and adjusting mechanism 31 installed on the quick-freezing production line 1, the adjusting end of the lifting and adjusting mechanism 31 is connected to the press detector, the press detector includes a press frame 33 rotatably installed on the lifting and adjusting mechanism 31, and the lower pressing end of the press frame 33 is installed with a rotating detection wheel 34, the press detector also includes an inductive pushing device 32 installed on the lifting and adjusting mechanism 31, and the extending end of the inductive pushing device 32 is in contact with one side of the press frame 33.

[0050] The lifting adjustment mechanism 31 serves as an adjustment basis, and an adjustment end of the lifting adjustment mechanism 31 is connected to the press detector to achieve precise adjustment of the height of the press detector.

[0051] In the working process, the lifting and lowering adjustment mechanism 31 first pre-adjusts the height of the pressing detector according to the specifications of the duck blood product 6 to enhance the adaptability of the detection. Subsequently, when the duck blood product 6 moves along the production line to the bottom of the continuous freezing detection device 3 with the limiting placement device 2, the rotating detection wheel 34 on the pressing detector maintains a stable rotating downward pressing state under the drive of the induction pushing device 32. At this time, the rotating detection wheel 34 enters from the insertion port 22 of the limiting placement groove 21 and forms a stable fit with the top of the duck blood product 6.

[0052] By directly contacting the rotating detection wheel 34 with the surface of the duck blood product 6, the rotating detection wheel 34 can effectively detect the surface strength of the duck blood product 6. The rotating detection wheel 34 directly reflects the freezing state of the duck blood product 6 with the strength parameter. If the duck blood product 6 has achieved the expected freezing effect, its surface strength will meet the preset standard; on the contrary, if the freezing is insufficient, the surface strength will be correspondingly weakened.

[0053] See also Figures 6 to 8 As shown, the lifting and adjusting mechanism 31 includes a mounting base 311 fixedly mounted on the quick-freezing production line 1, a lifting and mounting frame 312 is mounted on the mounting base 311, a plurality of first limit holes are arranged on the lifting and mounting frame 312, a limit guide column 313 is installed between the lifting and mounting frame 312 and the mounting base 311, an anti-rotation adjusting screw rod 314 is also installed between the lifting and mounting frame 312 and the mounting base 311, the anti-rotation adjusting screw rod 314 is rotatably connected to the lifting and mounting frame 312, the anti-rotation adjusting screw rod 314 is threadedly connected to the mounting base 311, and a plurality of second limit holes 3141 are also arranged on the anti-rotation adjusting screw rod 314.

[0054] In the process of adjusting the overall height of the press detector, the operator rotates the anti-rotation adjustment screw 314 and uses the principle of threaded transmission to drive the lifting mounting frame 312 to perform a stable upward or downward movement along the limit guide column 313, thereby achieving precise control of the height of the press detector. When the lifting mounting frame 312 is adjusted to the desired position, the operator uses the positioning pin to pass through the corresponding first limit card hole and second limit card hole 3141 respectively to lock the position of the anti-rotation adjustment screw 314, effectively preventing the screw from rotating due to factors such as equipment vibration, ensuring that the adjusted height remains stable, and thus ensuring the accuracy and reliability of the press detector during the detection process.

[0055] See also Figures 6 to 8As shown, the inductive pushing device 32 includes a mounting sleeve 321 fixedly mounted on the lifting mounting frame 312, a telescopic resistance rod 322 is installed inside the mounting sleeve 321, a first pushing spring 323 is installed between the telescopic resistance rod 322 and the mounting sleeve 321, and a first pressure sensor 324 is also installed inside the mounting sleeve 321.

[0056] In the working state, when the duck blood product 6 moves along the production line to the bottom of the continuous freezing measuring device 3, the first push spring 323 applies a thrust to the pressing frame 33 through the telescopic contact rod 322, ensuring that the pressing frame 33 and the rotating detection wheel 34 thereon can stably contact the top of the duck blood product 6. In this process, the displacement of the telescopic contact rod 322 is precisely controlled by the first push spring 323 to achieve a constant downward pressure. At the same time, the first pressure sensor 324 configured inside the mounting sleeve 321 can monitor the stress state of the first push spring 323 in real time. By measuring the spring pressure, the contact state between the rotating detection wheel 34 and the duck blood product 6 can be indirectly determined.

[0057] When the rotating detection wheel 34 forms a stable fit with the duck blood product 6, the first pressure sensor 324 will record a stable pressure value, indicating that the detection process is in progress.

[0058] See also Figures 6 to 9 As shown, a second pressure sensor 345 is installed on the outer wall of the rotating detection wheel 34, and an induction outer wheel 342 is also installed on the outer side of the rotating detection wheel 34. The induction outer wheel 342 is provided with a plurality of telescopic holes, and telescopic resistance blocks 343 are installed in each of the plurality of telescopic holes. The telescopic resistance blocks 343 are provided with a resistance shaft 344, and a second push spring 341 is installed between the telescopic resistance block 343 and the induction outer wheel 342.

[0059] The multiple telescopic holes on the induction outer wheel 342 are used to guide the movement of the telescopic resistance block 343. The telescopic resistance block 343 serves as a direct contact point between the induction outer wheel 342 and the duck blood product 6. Each telescopic resistance block 343 is equipped with a resistance shaft 344. The telescopic resistance block 343 is connected to the induction outer wheel 342 through a second push spring 341. The second push spring 341 provides a continuous outward thrust for the telescopic resistance block 343, ensuring that the telescopic resistance block 343 can remain in an extended state when no external force is applied.

[0060] In the working process, when the sensing outer wheel 342 contacts the duck blood product 6, the mechanical properties of the duck blood product 6 will directly affect the displacement of the telescopic resistance block 343. If the surface of the duck blood product 6 is frozen and hard, the telescopic resistance block 343 will be subjected to sufficient squeezing force and shrink toward the inside of the sensing outer wheel 342. This shrinking action will trigger the second pressure sensor 345, which will record and analyze the received pressure signal to determine whether the surface strength of the duck blood product 6 meets the preset standard.

[0061] On the contrary, if the surface of the duck blood product 6 is relatively soft, the contact between the inductive outer wheel 342 and the duck blood product 6 will not be sufficient to generate sufficient squeezing force to push the telescopic resistance block 343 to contract. In this case, the second pressure sensor 345 will record a low or no obvious pressure change, thereby judging that the frozen state of the duck blood product 6 does not meet the expected standard. Accurate detection of the surface strength of the duck blood product 6 is achieved, providing reliable technical support for quality control of the production line.

[0062] See also Figure 1 and Fig.10 As shown, the classification unloading device 4 includes a guide rail 41 , on which a first unloading rail 42 and a second unloading rail 43 are provided, and on which a shielding and regulating device 44 is provided.

[0063] A shielding control device 44 is provided above the first blanking rail 42 , and the shielding control device 44 has the function of dynamically controlling the shielding range.

[0064] In the production process, as the quick-freezing production line 1 continues to operate, the limiting placement device 2 carries the tested duck blood product 6 and moves to the top of the guide track 41. At this time, the guide track 41 plays its guiding and limiting role to ensure that the duck blood product 6 can move along the preset path.

[0065] After the continuous freezing detection device 3 completes the frozen state detection of the duck blood products 6, it sends a detection signal to the classification unloading device 4. According to the received signal, the shielding control device 44 adjusts its shielding range in real time. For the duck blood products 6 that are determined to be unqualified by the detection, when they move above the first unloading rail 42, due to the precise control of the shielding control device 44, the unqualified duck blood products 6 will smoothly fall into the first unloading rail 42. Subsequently, the first unloading rail 42 transports these unqualified duck blood products 6 to the reflux conveying device 5 for secondary freezing treatment.

[0066] As for the qualified duck blood products 6, when they move to the top of the first drop rail 42, they can smoothly avoid the first drop rail 42 due to the shielding range adjustment of the shielding control device 44, and continue to move to the top of the second drop rail 43 with the limit placement device 2. At this time, these qualified duck blood products 6 will naturally fall into the processing area with the second drop rail 43 for subsequent processing.

[0067] See also Fig.10 and Fig.11 As shown, the shielding control device 44 includes a plurality of flip scraper frames 441 rotating on the first blanking rail 42, and a linear driver 442 is installed on the side of each flip scraper frame 441, and a mounting block 443 is provided at the output end of the linear driver 442. A push adjustment rod 444 is installed between the mounting block 443 and the flip scraper frame 441, and one end of the push adjustment rod 444 is rotatably connected to the mounting block 443, and the end of the push adjustment rod 444 away from the mounting block 443 is rotatably connected to the flip scraper frame 441.

[0068] In the production process, as the quick-freezing production line 1 continues to operate, the tested duck blood product 6 is carried by the limiting placement device 2 and moved to the top of the guide track 41. At this time, the guide track 41 plays its guiding and limiting functions to ensure that the duck blood product 6 can move along the preset path.

[0069] When the continuous freezing detection device 3 completes the detection of the frozen state of the duck blood product 6, it will send a corresponding detection signal to the classification unloading device 4. According to the received signal, the corresponding linear driver 442 in the shielding control device 44 starts to work, pushing the push adjustment rod 444 to move. The movement of the push adjustment rod 444 will change the angle of the flip scraper frame 441, thereby realizing dynamic control of the shielding range.

[0070] For the duck blood product 6 that is determined to be unqualified by the detection, when the unqualified duck blood product 6 moves to the top of the first drop rail 42, since the flip scraper frame 441 is in the open state, that is, it does not cover the first drop rail 42, the unqualified duck blood product 6 will smoothly fall into the first drop rail 42. Subsequently, the first drop rail 42 conveys the unqualified duck blood product 6 to the reflux conveying device 5 for secondary freezing treatment.

[0071] As for the qualified duck blood products 6, when they move to the top of the first drop rail 42, since the flip scraper frame 441 is in a shielding state, that is, it blocks the top of the first drop rail 42, the qualified duck blood products 6 can smoothly avoid the first drop rail 42 and continue to move to the top of the second drop rail 43 with the limiting placement device 2. At this time, the qualified duck blood products 6 will naturally fall into the processing area with the second drop rail 43 for subsequent processing.

[0072] See also Figure 1 and Figure 2 As shown, the reflux conveying device 5 includes a synchronous conveyor 51 arranged beside the first material dropping rail 42, the input end of the synchronous conveyor 51 is arranged below the first material dropping rail 42, a material guide baffle 52 is installed at the input end of the synchronous conveyor 51, and a receiving hopper 53 is arranged at the output end of the synchronous conveyor 51.

[0073] The input end of the synchronous conveyor 51 is precisely arranged below the first drop rail 42 to ensure that unqualified duck blood products 6 can fall directly and accurately onto its conveying surface. At the input end of the synchronous conveyor 51, a material guide baffle 52 is installed. The material guide baffle 52 is used to guide the duck blood products 6 that slide out of the first drop rail 42 to ensure that the duck blood products 6 can fall smoothly onto the synchronous conveyor 51 to avoid deviation during the sliding process, thereby maintaining the continuity and stability of the conveying process. After the synchronous conveyor 51 is started, the unqualified duck blood products 6 are transported to the output end along a predetermined path. At the output end, a receiving hopper 53 is provided, which is used to receive and temporarily store the duck blood products 6 transported by the synchronous conveyor 51. The design of the receiving hopper 53 makes it easy for the staff to quickly and conveniently take away unqualified duck blood products 6 for subsequent secondary freezing treatment. The reflux conveying device 5 not only realizes the automatic and continuous conveying of unqualified duck blood products 6, but also significantly reduces the number of manual handling and labor intensity, thereby improving the automation level and production efficiency of the entire duck blood quick-freezing production line 1.

[0074] Specific working principle:

[0075] The limiting placement devices 2 are evenly distributed on the quick freezing production line 1 at equal intervals, and each limiting placement device 2 is provided with a plurality of limiting placement grooves 21 for limiting and supporting the packaged duck blood products 6. When the production line is started, the limiting placement device 2 moves synchronously with the production line, driving the duck blood products 6 to pass through the quick freezing area for quick freezing.

[0076] After quick freezing, the duck blood product 6 moves with the position limiting placement device 2 to the continuous freezing detection device 3. The continuous freezing detection device 3 is provided with a press detector corresponding to the position limiting placement slot 21, and the duck blood product 6 is pressed and detected in sequence to evaluate its freezing state. The press detector uses pressure sensing technology to accurately determine whether the duck blood has achieved the expected freezing effect.

[0077] According to the detection information provided by the continuous freezing detection device 3, the classification unloading device 4 makes corresponding adjustments. When the duck blood products 6 that have passed the test are moved to the classification unloading device 4, the classification unloading device 4 will transport the duck blood products 6 that have passed the test to the waiting area for subsequent use. For the duck blood products 6 that have failed the test, the classification unloading device 4 will transport them to the reflux conveying device 5.

[0078] The reflux conveying device 5 is located beside the classification unloading device 4, and is responsible for conveying the unqualified duck blood products 6 back to the freezing area. The staff can put the unqualified duck blood products 6 into the limiting placement device 2 again for secondary freezing treatment.

[0079] Through this process, the equipment not only achieves precise control of the quick-freezing efficiency of duck blood products 6, but also ensures the stability of the freezing quality. Through the coordinated work of the continuous freezing measuring device 3 and the classified unloading device 4, the problem of uneven freezing caused by the addition of regulators is effectively avoided, thereby improving the overall production efficiency. At the same time, the setting of the reflux conveying device 5 also facilitates the secondary processing of unqualified products, further improving the flexibility and efficiency of the production line.

[0080] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
