Description

Technical Field

[0001] This invention belongs to the field of aluminum foil rolling inspection technology, and in particular relates to a device for sampling without stopping the machine during the aluminum foil rolling process of batteries. Background Technology

[0002] During the aluminum foil rolling process, a thickness gauge is needed to control and monitor the rolled aluminum foil thickness. The working principle of the X-ray thickness gauge is as follows: after X-rays pass through the aluminum foil, some are absorbed, and the remaining part is received by the detector. By measuring the attenuation of the X-rays, combined with the density and absorption coefficient of the aluminum foil, the thickness of the aluminum foil is calculated. The thickness gauge amplifies and filters the received signal, converts the processed signal into a thickness value, displays it on the control panel, and transmits it to the control system to automatically adjust the rolling mill parameters to ensure that the thickness meets the requirements.

[0003] However, since thickness gauges calculate thickness using X-rays, impurities and oil mist in the air can affect the readings, making it impossible to guarantee the accuracy of the measurements. Therefore, after the predetermined thickness is reached, the rolling mill is usually stopped to take a sample for thickness measurement. Once the thickness is verified, rolling continues. Stopping the machine for sampling wastes time and reduces production efficiency. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention provides a device for sampling without stopping the machine during the battery aluminum foil rolling process, which improves work efficiency while ensuring the accuracy of thickness measurement and realizing efficient production of the rolling mill.

An upper pressure block is provided on the upper side of the sampling slot and a lower pressure block is provided on the lower side of the sampling slot. A sampling cylinder is slidably provided on the outer wall of the upper pressure block. When the sampling component moves at the same speed as the conveying aluminum foil, the upper pressure block and the lower pressure block together clamp the conveying aluminum foil, and the sampling cylinder presses downward to take the sample and leave the aluminum foil sample in the sampling cylinder.

[0007] Optionally, the flipping seat has a vertically penetrating groove that communicates with the sampling slot. A first rack is vertically mounted in the groove. A second cylinder is mounted on the bottom side of the flipping seat, and the piston rod of the second cylinder is connected to the bottom end of the first rack.

The third springs are used to drive the first wedge block and the second wedge block to move closer to each other, thereby linking the first locking block and the second locking block to move away from each other. A protective box is provided on the upper side of the flipping seat. The inner wall of the protective box is provided with a drive rod directly opposite the first guide post. When the upper and lower pressure blocks move away from each other, and the bottom end of the upper pressure block extends from the bottom side of the sampling cylinder, the first guide post is located inside the second rack, and the first and second locking blocks retract close to each other inside the first guide rod. When the upper and lower pressure blocks are pressed tightly together, and the sampling cylinder presses downwards and reaches the outside of the lower pressure block, the upper end of the first guide post extends from the upper end of the second rack, and the first and second locking blocks... The first guide post and the second rack are locked together by the third spring resetting and extending away from each other to the upper end of the second rack. When the first guide post and the second rack are locked together, the upper pressure block and the lower pressure block move away from each other, and the second rack drives the drive post to move upward and abut against the drive rod, thereby driving the first wedge block and the second wedge block to move away from each other.

When the flipping seat extends to the position of conveying aluminum foil, the collection box is arranged parallel to the flipping seat. When the flipping seat is folded and stored inside the sliding seat, the receiving plate is arranged in the sampling slot of the flipping seat and is located between the upper pressure block and the lower pressure block.

[0011] Optionally, a clearance ramp is provided on one side of the sampling slot to ensure that the flip seat and the receiving plate are staggered to avoid collision and interference when the flip seat is folded and stored.

[0012] Optionally, the guide rail assembly includes a first guide rail and a second guide rail disposed on a fixed base. A first slider is disposed on the upper and lower sides of the sliding base, and the first slider is slidably disposed on the first guide rail. A second slider is disposed on one side of the middle portion of the sliding base, and the second slider is slidably disposed on the second guide rail. Bearing seats are disposed at both ends of the second guide rail. A pulley is disposed inside the bearing seat and connected to a conveyor belt.

[0013] Optionally, the first guide post has countersunk threaded holes symmetrically arranged on both sides, which communicate with the spring groove. A guide screw is provided in the countersunk threaded hole, and the third spring is sleeved on the outside of the guide screw. A guide post is provided on the bottom side of the linkage block, and a fourth spring is sleeved on the outside of the guide post.

[0014] The present invention has the following advantages and beneficial effects: In this invention, by setting a guide rail assembly on one side of the aluminum foil conveying process and making the sampling assembly move along the guide rail assembly at the same speed as the conveying aluminum foil, sampling can be performed without stopping the machine during the aluminum foil rolling process, which improves work efficiency while ensuring the accuracy of thickness measurement and realizing high-efficiency production of the rolling mill.

[0015] By designing a flip seat and a sliding seat, the flip seat extends from inside the sliding seat to the aluminum foil position for sampling. The aluminum foil is clamped and conveyed by symmetrically arranged upper and lower pressure blocks. The sampling cylinder presses downward to take the sample and keeps the aluminum foil sample inside the sampling cylinder. After sampling, the aluminum foil sample can be stored, avoiding the situation where the aluminum foil sample cannot be collected after sampling and detaching from the sampling cylinder. After sampling, the flip seat flips back into the sliding seat, and the aluminum foil sample can be taken out, achieving efficient sampling. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] Example 1 like Figure 1 As shown, a work roll 11, a profile roll 12, a corner roll 13, and a guide roll 14 are arranged sequentially at the mill exit end. Aluminum foil 1 is rolled out and passed through these rolls in sequence. The sampling device of this invention is located on one side of the aluminum foil 1 being conveyed, and is positioned between the work roll 11 and the corner roll 13. A track-running device is installed at the mill exit end, and a sampling device is placed on the track. When the predetermined thickness is reached, the mill speed is generally 150 m / min, and the sampling device runs synchronously with the rolling speed to take samples during the rolling process of aluminum foil 1. The distance between the work roll 11 and the corner roll 13 is 1600 mm. According to GB / 22638.1 "Test Methods for Aluminum Foil 1 - Part 1: Determination of Thickness", when the thickness of aluminum foil 1 is <0.1 mm, the area of ​​the circular punch is 100 cm². 2 .

[0021] During normal operation of the rolling mill, the shape roller 12 will rise to lift the aluminum foil 1 and the corner roller 13 will press down to apply force to test the shape of the sheet. When sampling is required, the shape roller 12 will be lowered and the corner roller 13 will be raised for a short time, so that the aluminum foil 1 is in a horizontal running state between the work roller 11 and the corner roller 13, which can complete the sampling.

[0022] like Figure 2 As shown, a device for sampling without stopping the machine during the rolling process of aluminum foil for batteries includes a guide rail assembly disposed on one side of the aluminum foil 1 being conveyed, and a sampling component slidably disposed along the guide rail assembly. The moving direction of the sampling component is the same as the conveying direction of the aluminum foil 1. The guide rail assembly is disposed between the work roll 11 and the corner roll 13, and is located on one side of the aluminum foil 1 being conveyed.

[0023] like Figures 2 to 17 , Figures 20-24As shown, the sampling assembly includes a sliding seat 3 and a flipping seat 4. One side of the sliding seat 3 is hinged to the flipping seat 4. A drive arm 48 is provided on the flipping seat 4. A first cylinder 10 is hinged inside the sliding seat 3. The piston rod of the first cylinder 10 is hinged to the drive arm 48. The first cylinder 10 is used to drive the flipping seat 4 to flip and fold into the sliding seat 3, or to drive the flipping seat 4 to flip and extend to the position of conveying aluminum foil 1 for sampling.

[0024] like Figures 2 to 17 , Figures 20-24 As shown, specifically, a mounting block 31 extends from one side of the sliding seat 3, a first rotating shaft 32 is disposed between two mounting blocks 31, and a positioning block 33 is also disposed between the two mounting blocks 31, with the positioning block 33 and the first rotating shaft 32 spaced apart. The flip seat 4 has symmetrical clearance grooves 49 on its upper and lower sides, with a second pin hole 491 passing through the clearance groove 49. The first rotating shaft 32 is rotatably disposed in the second pin hole 491, and the mounting blocks 31 are respectively located in the clearance grooves 49. When the flip seat 4 rotates relative to the sliding seat 3, the flip seat 4 rotates around the first rotating shaft 32. The design of the clearance grooves 49 can prevent the flip seat 4 from colliding and interfering with the mounting blocks 31 during rotation. A first cylinder groove 35 is provided on one side of the sliding seat 3, and a first pin hole 36 is provided on the first cylinder groove 35. The first cylinder groove 35 and the positioning block 33 are arranged opposite to each other. One end of the first cylinder 10 is rotatably connected to the first pin hole 36 by a pin. The drive arm 48 is inclined towards the second pin hole 491, and the end of the piston rod inside the first cylinder 10 is hinged to the drive arm 48. In this way, when the first cylinder 10 extends, the drive tilting seat 4 is folded inside the sliding seat 3 and offset from the conveying aluminum foil 1 (e.g., Figure 7 As shown); when the first cylinder 10 retracts, it drives the tilting seat 4 to unfold and reach the position of the conveying aluminum foil 1 for sampling. At this time, the conveying aluminum foil 1 passes through the inside of the tilting seat 4 (as shown). Figure 3 As shown), when the flip seat 4 is unfolded, the side wall of the flip seat 4 is in close contact with the positioning block 33 to achieve the maximum angle of unfolding and limit the flip angle of the flip seat 4 to 90 degrees.

[0025] like Figures 2 to 17 , Figures 20-24 As shown, a sampling slot 41 is provided in the middle of the flipping seat 4. An upper pressure block 51 is provided on the upper side of the sampling slot 41 and a lower pressure block 75 is provided on the lower side of the sampling slot 41. A sampling cylinder 6 is slidably provided on the outer wall of the upper pressure block 51. When the sampling component moves at the same speed as the conveying aluminum foil 1, the upper pressure block 51 and the lower pressure block 75 together clamp the conveying aluminum foil 1, and the sampling cylinder 6 presses down to take the sample and leave the aluminum foil 1 sample in the sampling cylinder 6.

[0026] In this invention, the lifting and lowering movements of the upper pressure block 51, the lower pressure block 75, and the sampling cylinder 6 can be achieved by designing one or more driving mechanisms.

[0027] Furthermore, the bottom side of the sampling cylinder 6 is provided with an annular punching part 62, and the inner wall of the sampling cylinder 6 is provided with an elastic washer 63; the upper end of the upper pressure block 51 is integrally connected with a first sliding part 5, which slides closely against the inner wall of the sampling cylinder 6, and the elastic washer 63 is provided on the outer side of the upper pressure block 51. When the upper pressure block 51 moves up and down relative to the sampling cylinder 6, the upper pressure block 51 will not collide or interfere with the elastic washer 63. When the sampling cylinder 6 descends to punch and sample, the aluminum foil 1 sample is stored on the lower pressure block 75. Through the joint clamping and limiting by the upper pressure block 51 and the lower pressure block 75, the sampling cylinder 6 descends relative to the lower pressure block 75, and the elastic washer 63 descends to the bottom side of the aluminum foil 1 sample, thereby supporting the aluminum foil 1 sample on the upper side of the elastic washer 63. This realizes the function of the sampling cylinder 6 punching downward to sample and keeping the aluminum foil 1 sample inside the sampling cylinder 6.

[0028] In this invention, by setting a guide rail assembly on one side of the aluminum foil 1 and making the sampling assembly move along the guide rail assembly at the same speed as the aluminum foil 1, sampling can be performed without stopping the machine during the rolling process of the aluminum foil 1, thereby improving work efficiency and ensuring the accuracy of thickness measurement, and achieving high-efficiency production of the rolling mill.

[0029] Through the design of the flip seat 4 and the sliding seat 3, the flip seat 4 extends from inside the sliding seat 3 to the position of the aluminum foil 1 for sampling. The aluminum foil 1 is clamped and conveyed by the symmetrically arranged upper pressure block 51 and lower pressure block 75. The sampling cylinder 6 presses downward to take the sample and keeps the aluminum foil 1 sample in the sampling cylinder 6. After sampling, the aluminum foil 1 sample can be stored, avoiding the situation where the aluminum foil 1 sample is separated from the sampling cylinder 6 after sampling, which would result in the inability to collect the sample. After sampling is completed, the flip seat 4 flips back into the sliding seat 3, and the aluminum foil 1 sample can be taken out, thus achieving efficient sampling.

[0030] Example 2 In this embodiment, the lifting and lowering motion control of the upper pressure block 51, the lower pressure block 75, and the sampling cylinder 6 is further designed.

[0031] like Figures 2 to 17 , Figures 20-24As shown, the flip base 4 has a vertically penetrating groove 42 communicating with the sampling slot 41. A first rack 72 is vertically mounted within the groove 42. Specifically, guide rail grooves 421 are symmetrically recessed on both sides of the groove 42, and a third guide rail 79 is detachably fixed within the guide rail grooves 421. The first rack 72 is elongated, and guide rail grooves that mate with the third guide rail 79 are symmetrically opened on both sides of the first rack 72. The first rack 72 is slidably connected to the third guide rail 79 through the guide rail grooves. A second cylinder 7 is mounted on the bottom side of the flip base 4. The first piston rod 71 of the second cylinder 7 is connected to the bottom end of the first rack 72, and the second cylinder 7 controls the lifting and lowering movement of the first rack 72. The second cylinder 7 has cylinder seats 711 symmetrically arranged on both sides. The second cylinder 7 is partially locked in the guide rail groove 421. The bottom side of the guide rail groove 421 has a second cylinder groove 423. The cylinder seats 711 are installed in the second cylinder groove 423 by screws to fix the second cylinder 7.

[0032] like Figures 2 to 17 , Figures 20-24 As shown, the flip base 4 is vertically arranged from top to bottom with a first guide groove 43, a second guide groove 44, a third guide groove 45, and a fourth guide groove 46. The first guide groove 43 is square, while the second, third, and fourth guide grooves 44 and 45 are all circular. The first and second guide grooves 43 and 44 are located above the through groove 42, while the third and fourth guide grooves 45 and 46 are located below the through groove 42. The first and second guide grooves 43 and 44, as well as the third guide groove 45, are connected to the through groove 42. A second rack 61 is integrally connected to the upper end of the sampling cylinder 6. The second rack 61 is slidably disposed in the first guide groove 43, and the sampling cylinder 6 is slidably disposed in the second guide groove 44, thereby limiting the lifting and lowering of the sampling cylinder 6 and preventing rotational movement. A second rotating shaft 422 is provided on the upper inner wall of the through groove 42. A gear 73 is rotatably mounted on the second rotating shaft 422. The gear 73 is located between the first rack 72 and the second rack 61, and the gear 73 is meshed with the first rack 72 and the second rack 61 on both sides respectively. The sampling cylinder 6 is moved up and down through the gear and rack mechanism.

[0033] like Figures 2 to 17 , Figures 20-24As shown, a first guide post 52 is integrally connected to the upper end of the first sliding part 5. A guide square hole 611 is provided through the interior of the second rack 61. The first guide post 52 is slidably disposed on the inner wall of the guide square hole 611 of the second rack 61, realizing the lifting and lowering limit of the upper pressure block 51 and preventing the upper pressure block 51 from rotating. A first spring 53 is sleeved on the outside of the first guide post 52. One end of the first spring 53 is connected to the first sliding part 5, and the other end is connected to the inner wall of the sampling cylinder 6. The upper pressure block 51 is connected to the inside of the sampling cylinder 6 by the first spring 53. When the first spring 53 is not compressed or stretched, the bottom side of the upper pressure block 51 extends a certain distance from the bottom end of the sampling cylinder 6 (e.g., Figure 17 (As shown).

[0034] like Figures 2 to 17 , Figures 20-24 As shown, a support block 721 is laterally arranged on the bottom side of the first rack 72. A second sliding part 74 is integrally connected to the lower end of the lower pressure block 75. The second sliding part 74 is slidably disposed in the third guide groove 45. A circular second guide post 77 is integrally connected to the lower end of the second sliding part 74. The second guide post 77 passes through the support block 721 and is slidably disposed on the inner wall of the third guide groove 45. A second spring 76 is sleeved on the outside of the second guide post 77. One end of the second spring 76 is connected to the second sliding part 74, and the other end is connected to the support block 721. A square third guide post 78 is provided on one side of the second sliding part 74. The third guide post 78 is slidably disposed on the inner wall of the support block 721 to realize the lifting and lowering limit of the lower pressure block 75 and prevent the lower pressure block 75 from rotating.

[0035] A locking mechanism is provided on the second rack 61. The locking mechanism is used to fix the first guide post 52 and the second rack 61 together, or to release the fixation between the first guide post 52 and the second rack 61. This allows the aluminum foil 1 sample to be stored in the sampling cylinder 6 after sampling, and the aluminum foil 1 sample inside the sampling cylinder 6 to be taken out.

[0036] like Figure 3 and Figure 8 As shown, the flipping seat 4 is first flipped to the position of conveying aluminum foil 1. The conveyed aluminum foil 1 passes through the sampling slot 41 of the flipping seat 4. When no sampling is performed, the upper pressure block 51 and the lower pressure block 75 are far apart from each other and a certain distance apart. At this time, the conveyed aluminum foil 1 is located between the upper pressure block 51 and the lower pressure block 75, and neither the upper pressure block 51 nor the lower pressure block 75 is in contact with the aluminum foil 1. At this time, the first spring 53 and the second spring 76 are in their original state and are not compressed or stretched.

[0037] like Figure 10 and Figure 12As shown, during sampling, the second cylinder 7 is gradually extended. Through the linkage of the first rack 72 and the second rack 61, the upper pressure block 51 and the lower pressure block 75 approach each other and adhere tightly to the aluminum foil 1. When the upper pressure block 51 and the lower pressure block 75 are tightly adhered to the aluminum foil 1, the second cylinder 7 is extended again. The upper pressure block 51 and the lower pressure block 75 interact with each other and remain in the same position. At this time, the first spring 53 and the second spring 76 are compressed, and the sampling cylinder 6 moves downward, passing through the upper pressure block 51 and the lower pressure block 75 in sequence to punch the aluminum foil 1. When the sampling cylinder 6 descends to punch and sample, the aluminum foil 1 sample is placed on the lower pressure block 75. The sampling cylinder 6 descends relative to the lower pressure block 75, and the linkage elastic washer 63 descends to the bottom side of the aluminum foil 1 sample, thereby supporting the aluminum foil 1 sample on the upper side of the elastic washer 63. This achieves the function of the sampling cylinder 6 punching downward to sample and keeping the aluminum foil 1 sample inside the sampling cylinder 6.

[0038] like Figure 13 and Figure 14 As shown, after the sampling cylinder 6 completes the downward punching of the sample, the locking mechanism fixes the first guide post 52 and the second rack 61 into one unit, that is, fixes the sampling cylinder 6 and the upper pressure block 51 into one unit. Then, the second cylinder 7 is controlled to retract. Through the linkage of the first rack 72 and the second rack 61, the upper pressure block 51 and the lower pressure block 75 move away from each other. During this process, the second spring 76 gradually returns to its original position. The height of the lower pressure block 75 hardly changes, but the sampling cylinder 6 and the upper pressure block 51 are fixed into one unit. Therefore, the sampling cylinder 6 and the upper pressure block 51 rise synchronously and separate from the conveyed aluminum foil 1, and the aluminum foil 1 sample is stored in the sampling cylinder 6.

[0039] like Figure 7 and Figure 15 As shown, the first cylinder 10 can then be extended to drive the flipping seat 4 to flip away from the conveying aluminum foil 1. Then the locking mechanism releases the fixation between the first guide post 52 and the second rack 61, the first spring 53 resets, and drives the lower pressure block 75 to descend relative to the sampling cylinder 6. The upper pressure block 51 descends to the bottom side of the sampling cylinder 6 and returns to its original state, pushing the aluminum foil 1 sample stored inside the sampling cylinder 6 out of the sampling cylinder 6, thus achieving the separation of the aluminum foil 1 sample from the sampling cylinder 6.

[0040] In this invention, the upper pressure block 51 and the lower pressure block 75 are moved by the gear and rack mechanism to clamp and position the conveyed aluminum foil 1, and then the sampling cylinder 6 is lowered to perform the sampling operation. After sampling, the sample can be stored inside the sampling cylinder 6 to avoid the aluminum foil 1 sample falling on the conveyed aluminum foil 1, which would cause the sampled aluminum foil 1 sample to be unable to be collected in time. Subsequently, the aluminum foil 1 sample can be quickly taken out from inside the sampling cylinder 6, realizing efficient sampling of the conveyed aluminum foil 1.

[0041] Example 3 In this embodiment, a locking mechanism is further designed, which is driven by the second cylinder 7 to realize the movement functions of the upper pressure block 51, the lower pressure block 75, the sampling cylinder 6, and the locking mechanism.

[0042] like Figure 17 , Figure 18 , Figures 24-29 As shown, the locking mechanism includes a first locking block 82, a second locking block 83, and a linkage block 81. One side of the first locking block 82 is connected to a first wedge-shaped block 823 via two first sliding rods 822. The first locking block 82 is hollow inside, and a first side block 821 is provided on one side of the first locking block 82. One end of the second locking block 83 is connected to a second wedge-shaped block 833 via two second sliding rods 832. The second locking block 83 is hollow inside, and a second side block 831 is provided on one side of the second locking block 83. The first wedge-shaped block 823 has two first sliding holes 824 located on the bottom side of the first sliding rod 822. The second wedge-shaped block 833 has two second sliding holes 834 located on the upper side of the second sliding rod 832. The first slide rod 822 is slidably disposed on the inner wall of the second slide hole 834, and the second slide rod 832 is slidably disposed on the inner wall of the first slide hole 824. The first slide rod 822 and the second slide rod 832 are staggered vertically, so that the first locking block 82 and the second locking block 83 are slidably disposed relative to each other. The first wedge block 823 and the second wedge block 833 are disposed opposite to each other, and the first locking block 82 and the second locking block 83 are disposed opposite to each other.

[0043] like Figure 9 , Figure 11 , Figure 17 , Figure 18 , Figures 24-29As shown, a first sliding groove 521 is horizontally formed inside the upper end of the first guide post 52. The first locking block 82 and the second locking block 83 are slidably disposed in the first sliding groove 521. A second sliding groove 522, which communicates with the first sliding groove 521, is vertically formed at the upper end of the first guide post 52. A drive post 8 is provided at the upper end of the linkage block 81, and the drive post 8 is slidably disposed in the second sliding groove 522. A mating inclined surface 811 is symmetrically provided on the bottom side of the linkage block 81. The first wedge block 823 and the second wedge block 833 are respectively mated with the mating inclined surface 811. Two sliding rod grooves 812 are provided through the bottom side of the linkage block 81. The sliding rod is disposed in the sliding rod groove 812. During the lifting and lowering process of the linkage block 81, the existence of the sliding rod groove 812 enables the linkage block 81 to avoid collision with the first sliding rod 822 and the second sliding rod 832. The bottom side of the first slide groove 521 is provided with a spring groove 524, and two third springs 85 are symmetrically arranged in the spring groove 524. The first wedge block 823 and the second wedge block 833 are respectively connected to the corresponding third springs 85. The third springs 85 are used to drive the first wedge block 823 and the second wedge block 833 to move closer to each other, thereby realizing the first locking block 82 and the second locking block 83 moving away from each other. The first guide post 52 is provided with countersunk threaded holes 523 on both sides, which communicate with the spring groove 524. The countersunk threaded holes 523 are provided with guide screws 84, and the third springs 85 are sleeved on the outside of the guide screws 84. The bottom side of the linkage block 81 is provided with a guide post, and a fourth spring 813 is sleeved on the outside of the guide post. A first baffle 825 is provided on the bottom side of the first wedge block 823, and a second baffle 835 is provided on the bottom side of the second wedge block 833. The first baffle 825 and the second baffle 835 are both provided in the spring groove 524, and the first baffle 825 and the second baffle 835 respectively abut against one end of the third spring 85.

[0044] like Figure 9 As shown, a protective box 9 is provided on the upper side of the flip seat 4, and a drive rod 91 is provided on the inner wall of the protective box 9, which is directly opposite to the first guide post 52.

[0045] like Figure 8 and Figure 9 As shown, when the upper pressure block 51 and the lower pressure block 75 are far apart from each other, and the bottom end of the upper pressure block 51 extends from the bottom side of the sampling cylinder 6, both the upper pressure block 51 and the lower pressure block 75 are at a distance from the conveying aluminum foil 1. The first guide post 52 is located inside the second rack 61, and the first locking block 82 and the second locking block 83 are close to each other and retract inside the first guide post 52. In this state, the third spring 85 is stretched.

[0046] like Figure 10 and Figure 11As shown, when the upper pressure block 51 and the lower pressure block 75 are pressed tightly together, and the sampling cylinder 6 is pressed downward and reaches the outside of the lower pressure block 75, the sampling operation is completed. When the sampling cylinder 6 descends relative to the upper pressure block 51, the upper end of the first guide post 52 extends from the upper end of the second rack 61. After the first locking block 82 and the second locking block 83 are disengaged from the limit of the guide square hole 611, the first locking block 82 and the second locking block 83 are reset by the third spring 85 and move away from each other, extending to the upper end of the second rack 61 to lock the first guide post 52 and the second rack 61. At this time, the first spring 53 is compressed, and the upper pressure block 51 and the sampling cylinder 6 are fixed as one body.

[0047] like Figure 13 , Figure 14 and Figure 19 As shown, when the first guide post 52 and the second rack 61 are locked together, the upper pressure block 51 and the lower pressure block 75 move away from each other. The second rack 61, along with the sampling cylinder 6, the upper pressure block 51, and the first guide post 52, rises synchronously, driving the drive post 8 upward and abutting against the drive rod 91. This drives the linkage block 81 downward, which in turn engages with the first wedge block 823 and the second wedge block 833, thereby driving the first wedge block 823 and the second wedge block 833 to move away from each other. The third spring... When the spring 85 is compressed, the first locking block 82 and the second locking block 83 move closer to each other and retract inside the first guide post 52. When the first locking block 82 and the second locking block 83 disengage from the upper end face of the second rack 61, the first spring 53 resets and drives the first guide post 52 to descend relative to the second rack 61, that is, the upper pressure block 51 descends relative to the sampling cylinder 6. The first guide post 52 retracts in the guide square hole 611, and the upper pressure block 51 extends from the bottom end of the sampling cylinder 6 to push the aluminum foil 1 sample out of the sampling cylinder 6.

[0048] In this invention, by structurally designing the locking mechanism, the movement patterns of the upper pressure block 51, the lower pressure block 75, and the sampling cylinder 6 are fully utilized to achieve the design of the locking mechanism, thereby fixing and releasing the sampling cylinder 6 and the upper pressure block 51. The structure is ingenious and can be achieved with only one drive from the second cylinder 7.

[0049] Example 4 To further achieve efficient sampling of aluminum foil sample 1, further design was developed.

[0050] Figures 2-24 As shown, a collection box 38 is provided at the bottom of one side of the sliding seat 3, and a receiving plate 39 is inclinedly provided on one side of the collection box 38. The collection box 38 is located at the bottom side of the first cylinder 10, and will not interfere with it when the first cylinder 10 is operated. Figure 3 , Figure 5 As shown, when the tilting seat 4 extends to the position of conveying aluminum foil 1, the collection box 38 is arranged parallel to the tilting seat 4; as Figure 7 and Figure 15As shown, when the flip seat 4 is folded and stored inside the sliding seat 3, the receiving plate 39 is set in the sampling slot 41 of the flip seat 4, and the receiving plate 39 is set between the upper pressure block 51 and the lower pressure block 75, so that the aluminum foil 1 sample can be received.

[0051] Furthermore, a clearance slope 47 is provided on one side of the sampling slot 41 to ensure that the flip seat 4 is staggered from the receiving plate 39 when the flip seat 4 is folded and stored, thus avoiding collision and interference.

[0052] like Figure 13 and Figure 14 As shown, the upper pressure block 51 is positioned inside the sampling cylinder 6, and the aluminum foil 1 sample is stored on the elastic washer 63 inside the sampling cylinder 6. Then, the first cylinder 10 can be extended to drive the flipping seat 4 to flip away from the aluminum foil 1.

[0053] like Figure 7 and Figure 15 As shown, the first cylinder 10 extends, driving the tilting seat 4 to tilt away from the conveying aluminum foil 1. Then, the locking mechanism releases the fixation between the first guide post 52 and the second rack 61, the first spring 53 resets, and drives the lower pressure block 75 to descend relative to the sampling cylinder 6. The upper pressure block 51 descends to the bottom side of the sampling cylinder 6, pushing out the aluminum foil 1 sample inside the sampling cylinder 6. The aluminum foil 1 sample falls onto the receiving plate 39 on the bottom side and is finally collected in the collection box 38. During the rotation of the tilting seat 4, one side of the lower pressure block 75 will contact the bottom side of the receiving plate 39, thereby driving the lower pressure block 75 to descend. During this period, the second spring 76 is compressed, realizing the misalignment of the receiving plate 39 and the lower pressure block 75, avoiding hard collision interference, and realizing the function of the receiving plate 39 to receive the sample.

[0054] Example 5 In this invention, the movement of the sliding seat 3 is achieved using a belt conveyor mechanism. The guide rail assembly includes a first guide rail 21 and a second guide rail 22 mounted on the fixed seat 2. Two first guide rails 21 and one second guide rail 22 are provided, arranged in a triangular configuration. Connecting blocks 34 are respectively provided on the upper and lower sides of the sliding seat 3. A first slider 23 is detachably mounted on the connecting block 34, and the first slider 23 is slidably mounted on the first guide rail 21 to achieve sliding limit of the sliding seat 3. The connecting block 34 and the mounting block 31 are reinforcedly connected by a stiffening plate 341. A slider groove 37 is provided on one side of the middle of the sliding seat 3. A second slider 24 is detachably fixed in the slider groove 37. The second slider 24 is slidably mounted on the second guide rail 22. The second guide rail 22 is hollow inside. Bearing seats 25 are provided at both ends of the second guide rail 22. A pulley is provided inside the bearing seat 25 and connected to a conveyor belt 27. One side of the conveyor belt 27 is located inside the second guide rail 22, and the other side is located outside the second guide rail 22 and fixedly connected to the second slider 24. A drive motor 26 is provided on the bearing seat 25 to drive the conveyor belt 27. The drive motor 26 is connected to the pulley inside the bearing seat 25 for transmission. The movement of the sliding seat 3 is achieved by controlling the movement of the conveyor belt 27 through the drive motor 26.
