Description

Technical Field

[0001] This invention belongs to the field of solvent residue determination technology, and specifically relates to a sample bottling device for solvent residue determination. Background Technology

[0002] The National Tobacco Quality Supervision and Inspection Center has released the "Testing Technology for Cigarette Cartons and Packaging Paper." The document clarifies the area and location for cutting the paper sample in the solvent residue determination process. The cut paper sample should be rolled into a tube with the printed side facing inwards and immediately placed in a headspace vial. Currently, the industry commonly uses manual rolling, but this method is slow, and the limited size of the headspace vial opening makes it difficult to accurately control the diameter of the rolled paper. This can lead to situations where the rolled paper cannot be placed in the headspace vial, requiring re-rolling, resulting in low overall efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a sample bottling device for solvent residue determination that can improve the rolling efficiency and bottling efficiency of paper samples and reduce the dependence on manual skill proficiency and training costs.

[0004] The content of this invention includes: A clamping and rotating mechanism includes a clamp and a rotating drive module. The clamp is provided with two clamping rods for clamping paper samples. The rotating drive module is used to drive the clamp to rotate about the length direction of the clamping rods as an axis. A pressing mechanism, comprising a pressure roller and a first transfer module, wherein the side of the pressure roller is disposed facing the side of at least one clamping rod, for pressing a paper sample wound on two clamping rods, and the first transfer module is used to drive the pressure roller to move parallel to the length direction of the clamping rods and / or move in a direction away from the side of the clamping rods; A bottling mechanism, comprising a bracket and a linear motion module, wherein the bracket is provided with a receiving groove for placing headspace bottles, and the bracket is provided with an opening communicating with the receiving groove on one side facing the ends of the two clamping rods so that the bottle mouth of the headspace bottle is exposed; the linear motion module is used to drive the bracket to move parallel to the length direction of the clamping rods so that the headspace bottle is fitted over the outside of the paper sample wound by the two clamping rods.

[0005] Furthermore, both clamping rods are semi-circular rods, with their planar sides facing each other, and the sum of the radii of the two clamping rods and the distance between them in the open state is less than the inner diameter of the headspace bottle neck.

[0006] Furthermore, the clamp is a pneumatic gripper, with one end of a single gripping rod fixed to a single gripping finger of the pneumatic gripper, and the gripping rotation mechanism further includes a pneumatic slip ring, the rotating part of which is connected to the pneumatic gripper.

[0007] Furthermore, the rotary drive module includes a slewing bearing and a first rotary drive component. The axial length of the inner ring of the slewing bearing is greater than that of the outer ring of the slewing bearing. A ring of teeth is provided on the outer side of the area where the inner ring of the slewing bearing protrudes axially from the outer ring of the slewing bearing. The first rotary drive component is disposed on the outer ring of the slewing bearing. A gear is provided on the output end of the first rotary drive component. The gear meshes with the teeth. The clamp is disposed in the inner ring of the slewing bearing.

[0008] Furthermore, a limiting protrusion is provided inside the receiving groove at the position corresponding to the neck of the headspace bottle, and the limiting protrusion extends in an arc shape along the direction from one side to the other inside the receiving groove.

[0009] Furthermore, the bottling mechanism also includes a restraint strap, one end of which is fixed to one side of the bracket, and the other end of which is detachably connected to the other side of the bracket via Velcro, to restrain the position of the headspace bottle above the receiving slot.

[0010] Furthermore, the pressing mechanism also includes a bracket, which is mounted on the first transfer module. The bottom of the bracket extends downward and has two support plates. Both support plates have oblong holes, and the length of the oblong holes is along the height of the support plates. The two ends of the pressure roller pass through the oblong holes of the two support plates, and the top of the oblong holes is connected to the pressure roller by an elastic element.

[0011] Furthermore, the axial length of the two clamping rods is greater than the axial length of the paper sample after winding, while the axial length of the pressure roller is less than the axial length of the two clamping rods.

[0012] Furthermore, the paper roll apparatus for solvent residue determination also includes a capping mechanism, and the bottling mechanism further includes a second rotary drive for driving the carriage to flip so that the bottle opening of the headspace bottle faces upward, and the capping mechanism is used to seal the bottle opening of the headspace bottle.

[0013] Furthermore, the capping mechanism includes a capper and a second transfer module, the second transfer module being used to drive the capper to move toward or away from the headspace bottle opening.

[0014] The beneficial effects of this invention are that by clamping and rotating the paper sample through a clamping and rotating mechanism, combined with the continuous pressure of the pressure roller, the paper sample can be quickly wound into a cylindrical shape. Compared with manual winding, this invention has high winding efficiency, and the diameter of the wound paper sample is highly controllable and consistent, effectively solving the problem that manually wound paper cannot be placed into the headspace vial due to its excessive diameter, requiring repeated rewinding. The bottling mechanism drives the headspace vial to move and fit over the paper sample wound by the two clamping rods. When the headspace vial resets, the natural expansion of the paper sample within the headspace vial, along with the blocking effect of the headspace vial neck, automatically completes the paper retention, improving the bottling efficiency of paper samples required for solvent residue determination. Furthermore, ordinary laboratory personnel can quickly complete sample preparation, reducing the dependence on manual skill and training costs associated with bottling operations.

[0022] Example 1 like Figures 1-4 As shown, the present invention provides a sample bottling device for solvent residue determination, including a clamping and rotating mechanism 2, a pressing mechanism 3, and a bottling mechanism 4. The clamping and rotating mechanism 2 includes a clamp 21 and a rotation drive module. The clamp 21 is provided with two clamping rods 22 for clamping a paper sample. The rotation drive module drives the clamp 21 to rotate about the length direction of the clamping rods 22. The pressing mechanism 3 includes a pressure roller 31 and a first transfer module. The side of the pressure roller 31 faces the side of at least one clamping rod 22 and is used to press down the paper sample wound on the two clamping rods 22. Based on this arrangement, when the paper sample is clamped between the two clamping rods 22 and rotates with them, the friction of the pressure roller 31 ensures that the paper sample is wound on the two clamping rods 22 and maintains its wound state. The first transfer module is used to drive the pressure roller 31 to move parallel to the length direction of the clamping rod 22 and / or move away from the side of the clamping rod 22, so as to make corresponding movements and avoid obstacles when preparing samples of the wound paper for bottling.

[0023] The bottling mechanism 4 includes a bracket 41 and a linear motion module 42. The bracket 41 is provided with a receiving groove 411 for placing a headspace bottle 5, and the bracket 41 has an opening 414 communicating with the receiving groove 411 on the side facing the ends of the two clamping rods 22, so that the bottle mouth of the headspace bottle 5 is exposed. Based on this configuration, when the headspace bottle 5 is placed in the receiving groove 411, the bottle mouth of the headspace bottle 5 faces the ends of the two clamping rods 22. Preferably, the height of the receiving groove 411 is configured such that when the headspace bottle 5 is placed, the axis of the headspace bottle 5 is flush with the centerline between the two clamping rods 22. The linear motion module 42 is used to drive the bracket 41 to move parallel to the length direction of the clamping rods 22, so that the headspace bottle 5 is fitted onto the outside of the paper sample wound by the two clamping rods 22.

[0024] Based on the above setup, a person manually places one end of the paper sample between the two clamping rods 22, aligning one side of the paper sample with the ends of the two clamping rods 22. The two clamping rods 22 clamp one end of the paper sample and rotate it. With the help of the pressure roller 31, the paper sample is wound around the sides of the two clamping rods 22. The person manually places the headspace bottle 5 into the receiving groove 411, then drives the bracket 41 to move parallel to the length direction of the clamping rods 22, and drives the pressure roller 31 to move parallel to the length direction of the clamping rods 22 and / or move away from the clamping rods 22 to avoid them. This allows the headspace bottle 5 to be fitted over the paper sample wound around the two clamping rods 22, so that the entire wound paper sample is located inside the headspace bottle 5. Based on the characteristics of paper winding, the paper sample will naturally stretch in the headspace bottle 5. The two clamping rods 22 are released from the paper sample, and the bracket 41 is driven to move and reset. During this process, the two clamping rods 22 gradually disengage from the headspace bottle 5. Due to the obstruction at the bottleneck of the headspace bottle 5, the paper sample remains in the headspace bottle 5, thus completing the bottling of the wound paper sample.

[0025] This invention uses a clamping and rotating mechanism 2 to clamp and rotate a paper sample, combined with the continuous pressure of a pressure roller 31, to quickly wind the paper sample into a cylindrical shape. Compared to manual winding, this invention offers higher winding efficiency and greater controllability and consistency in the diameter of the wound paper sample. It effectively solves the problem of manually winding paper that cannot fit into the headspace vial 5 due to its excessive diameter, requiring repeated rewinding. The bottling mechanism 4 drives the headspace vial 5 to move and fit over the paper sample wound by the two clamping rods 22. When the headspace vial 5 returns to its original position, the natural expansion of the paper sample within the vial 5, along with the blocking effect of the vial neck, automatically completes the paper retention, improving the bottling efficiency required for solvent residue determination. Furthermore, ordinary laboratory personnel can quickly complete sample preparation, reducing the reliance on manual skill and training costs associated with bottling operations.

[0026] Both clamping rods 22 are semi-circular rods, with their planar sides facing each other. In the clamping state, the two clamping rods 22 approximately form the side surface of a cylinder, with a high degree of consistency in their circumferential diameter, ensuring that the pressure roller 31 can effectively press down on the paper sample during winding. Simultaneously, the outer side of the wound paper sample is more rounded, facilitating its natural unfolding within the headspace vial 5. Furthermore, the sum of the radii of the two clamping rods 22 and the distance between them in the open state is less than the inner diameter of the headspace vial 5's neck, ensuring that the two clamping rods 22 can also disengage from the headspace vial 5 after being opened.

[0027] The clamp 21 is a pneumatic gripper, with one end of each gripping rod 22 fixed to a single gripping finger of the gripper. The gripping force of the pneumatic gripper is stable and adjustable, and the gripping stability and controllability are higher. The two gripping rods 22 are detachably fixed to the gripper by screws, which facilitates the replacement of new gripping rods 22 when problems such as tilting or bending occur.

[0028] The clamping and rotating mechanism 2 also includes a pneumatic slip ring 26. The rotating part of the pneumatic slip ring 26 is connected to the pneumatic gripper. Specifically, the air inlet and outlet of the pneumatic slip ring 26 are connected to the rotating part of the pneumatic slip ring 26 through an air pipe, and the fixing part of the pneumatic slip ring 26 is connected to an external air circuit solenoid valve, which is connected to an external air source. Based on the configuration of the pneumatic slip ring 26, compressed air is provided to the pneumatic gripper during continuous rotation, preventing the air pipe from tangling or twisting. The invention also includes a base plate 1. The rotating drive module is mounted on the base plate 1 through a first mounting base 11. A first upright 12 is also provided on the base plate 1, and the fixing part of the pneumatic slip ring 26 is mounted on the first upright 12.

[0029] The rotary drive module includes a slewing bearing 23 and a first rotary drive component 24. The axial length of the inner ring of the slewing bearing 23 is greater than that of the outer ring. A ring of teeth 231 is provided on the outer side of the area where the inner ring of the slewing bearing 23 protrudes axially from the outer ring. The first rotary drive component 24 is mounted on the outer ring of the slewing bearing 23, and a gear 25 is provided on the output end of the first rotary drive component 24. The gear 25 meshes with the teeth 231. The clamp 21 is disposed in the inner ring of the slewing bearing 23. This structure utilizes the slewing bearing 23 for support, resulting in smooth operation and small clearance. The axially extended inner ring design not only provides ample installation space for the clamp 21 but also integrates the teeth 231 in the protruding part, achieving integrated drive and load-bearing, resulting in a compact structure that is conducive to overall miniaturization. Specifically, the rotary drive module consists of the outer ring of the slewing bearing 23 mounted on a first mounting base 11. The first rotary drive component 24 is specifically a motor.

[0030] The pressing mechanism 3 also includes a bracket 32, which is mounted on the first transfer module. Two support plates extend downwards from the bottom of the bracket 32, each with a waist-shaped hole 321. The length of the waist-shaped hole 321 is aligned with the height of the support plate. The two ends of the pressure roller 31 pass through the waist-shaped holes 321 on the two support plates, and the top of the waist-shaped hole 321 is connected to the pressure roller 31 via an elastic element 322. Based on this configuration, the pressure roller 31 is suspended in a floating manner. The position of the pressure roller 31 can float upwards as the winding thickness increases, while the elastic element 322 continuously provides a stable downward pressing force, ensuring that the pressure roller 31 always contacts the outer surface of the paper sample.

[0031] The pressure roller 31 has connecting posts at both ends, the diameter of which is smaller than the diameter of the pressure roller 31. Specifically, the connecting posts at both ends of the pressure roller 31 are inserted into the corresponding oblong holes 321. The elastic element 322 is specifically connected between the top of the oblong hole 321 and the connecting post. The elastic element 322 is specifically a rubber block or a spring.

[0032] The axial length of the two clamping rods 22 is greater than the axial length of the paper sample after winding, that is, the axial length of the two clamping rods 22 is greater than the length or width of the paper sample. The axial length of the pressure roller 31 is less than the axial length of the two clamping rods 22. Based on this arrangement, the two clamping rods 22 have a margin in the length direction for the pressure roller 31 to move parallel to each other, so that when the headspace bottle 5 moves with the bracket 41 toward the wound paper sample, the pressure roller 31 can move and avoid it while pressing the wound paper sample, so as to ensure that the wound paper sample can be stably and reliably loaded into the headspace bottle 5. Moreover, compared with the rigidly set pressure roller 31, the floating pressure roller 31 applies less radial pressure to the two clamping rods 22 while pressing the wound paper sample, which helps to extend the service life of the clamping rods 22.

[0033] Specifically, such as Figure 4 Taking the perspective as an example, after the paper sample is clamped and wound, the linear motion module 42 drives the bracket 41 to move to the right along the Y direction, and the first transfer module moves the pressure roller 31 to the right along the Y direction. At this time, the left end of the wound paper sample gradually loses the pressure of the pressure roller 31, but the right end of the paper sample is still pressed by the pressure roller 31. Therefore, the left end of the paper sample will not loosen or only show a small degree of stretching. The headspace bottle 5 can normally cover the left end of the paper sample, and as the bracket 41 and the pressure roller 31 move to the right, most of the area of ​​the paper sample is filled into the headspace bottle 5. Then, by continuously moving the pressure roller 31 to the right or upward, the right end of the paper sample also loses the pressure of the pressure roller 31. Combined with the clamping and fixing of the paper sample by the two clamping rods 22 (the paper sample will not move along the axial length direction of the two clamping rods 22), and with the continuous rightward movement of the bracket 41, the entire wound paper sample is thus covered inside the headspace bottle 5.

[0034] The height from the bottom surface of the headspace bottle 5 to the lowest point of the neck is greater than the axial length of the wound paper sample, ensuring that the paper sample can be completely fitted inside the headspace bottle 5 within the bottle body area below the neck. Preferably, the axial length of the pressure roller 31 is less than half the axial length of the two clamping rods 22, ensuring that the two clamping rods 22 have sufficient margin in the length direction for the pressure roller 31 to move parallel to each other.

[0035] In one embodiment of the present invention, the first transfer module is a single-axis moving module, and the moving direction is along the axial length parallel to the two clamping rods 22.

[0036] In another embodiment of the present invention, the first transfer module is a two-axis moving module, used to drive the pressure roller 31 to move along the length direction parallel to the clamping rod 22 and away from the side of the clamping rod 22. Specifically, the first transfer module includes a first X-axis moving member 33 and a first Y-axis moving member 34. A second upright 13 is also provided on the base plate 1. The first Y-axis moving member 34 is mounted on the second upright 13 via a second mounting base 14. The first X-axis moving member 33 is mounted on the output end of the first Y-axis moving member 34, and a bracket 32 ​​is mounted on the output end of the first X-axis moving member 33. The first X-axis moving member 33 is used to drive the pressure roller 31 to move towards or away from the side of the clamping rod 22, and the first Y-axis moving member 34 is used to drive the pressure roller 31 to move parallel to the length direction of the clamping rod 22. This configuration allows the pressure roller 31 to have a two-axis travel. The first Y-axis moving component 34 can drive the pressure roller 31 upwards, increasing the distance between the pressure roller 31 and the sides of the two clamping rods 22, making it easier to replace the clamping rods 22. Furthermore, it provides more options for the movement path of the pressure roller 31, for example, in... Figure 4 From the perspective of the first Y-axis moving member 34, when the pressure roller 31 moves to the right along the X-axis until only the right end of the paper sample is pressed, the first Y-axis moving member 34 drives the pressure roller 31 to move upward to release the pressure on the paper sample.

[0037] The base plate 1 is also equipped with a first slide rail 15, the length direction of which is in the same direction as the moving drive direction of the first Y-axis moving member 34. A first slider 331 is provided on the first X-axis moving member 33, and the first slider 331 slides in conjunction with the first slide rail 15 to guide the movement of the first X-axis moving member 33, thereby improving the stability of the first X-axis moving member 33 during movement. The first X-axis moving member 33 and the first Y-axis moving member 34 are specifically linear modules, cylinders, or electric cylinders.

[0038] A limiting protrusion 412 is provided inside the receiving groove 411 at the position corresponding to the neck of the headspace bottle 5. The limiting protrusion 412 extends in an arc shape along the inside of the receiving groove 411 from one side to the other, and is used to axially limit the neck position of the headspace bottle 5 when it is placed in the receiving groove 411. This limiting protrusion 412 can both position the headspace bottle 5 and axially restrict the position of the headspace bottle 5 within the receiving groove 411, preventing the headspace bottle 5 from moving axially out of the receiving groove 411 along the opening 414 when the bracket 41 is reset, thus further improving the reliability during use.

[0039] The bottling mechanism 4 also includes a constraint strap 413. One end of the constraint strap 413 is fixed to one side of the bracket 41, and the other end of the constraint strap 413 is detachably connected to the other side of the bracket 41 via Velcro. For example, the burr side of the Velcro is located at the other end of the constraint strap 413, and the rounded side is located at the other side of the bracket 41. (See reference) Figure 4 As shown, by connecting the constraint strap 413 to the bracket 41, the position of the headspace bottle 5 can be constrained above the receiving groove 411, preventing the headspace bottle 5 from jumping upward or falling out when the bracket 41 moves or the device vibrates, thus further improving the reliability during use.

[0040] The linear motion module 42 is specifically mounted on the base plate 1 via the third mounting base 16, and is located below the two clamping rods 22. A second slide rail 17 is also provided on the base plate 1, with its length direction aligned with the moving drive direction of the linear motion module 42. A second slider 43 is provided at the bottom of the bracket 41, and the second slider 43 slides in conjunction with the second slide rail 17 to guide the movement of the bracket 41 and improve its stability during movement. The linear motion module 42 can be a linear module, a pneumatic cylinder, or an electric cylinder.

[0041] In this invention, the clamp 21, the first rotary drive 24, the first X-axis moving component 33, the first Y-axis moving component 34, and the linear motion module 42 are all electrically connected to an external controller. When the clamp 21 is a pneumatic gripper and the first X-axis moving component 33, the first Y-axis moving component 34, and the linear motion module 42 are cylinders, the pneumatic solenoid valves connected to the pneumatic gripper and the cylinders are electrically connected to the external controller.

[0042] In this first embodiment, the operator removes the headspace vial 5 containing the paper sample from the holder 41, and then manually adds the solution and seals the vial.

[0043] Example 2 like Figure 5 and Figure 6As shown, unlike Embodiment 1, Embodiment 2 further includes a capping mechanism 6, and the bottling mechanism 4 also includes a second rotary drive 46. The second rotary drive 46 is used to drive the bracket 41 to flip, and the capping mechanism 6 is used to seal the mouth of the headspace vial 5. In this Embodiment 2, after the paper sample is placed in the headspace vial 5, the bracket 41 is flipped by the second rotary drive 46 so that the mouth of the headspace vial 5 faces upward. After the operator drips the solution into the headspace vial 5, the cap is placed on the mouth, and then sealed by the capping mechanism 6. This Embodiment 2 eliminates the need for manual twisting or pressing of the capper 61, reducing the difficulty of capping and the reliance on manual skill.

[0044] The bottling mechanism 4 also includes a support base 44, on which the bracket 41 is rotatably mounted. Specifically, the support base 44 has a recessed arc-shaped groove with a semi-circular cross-section. A mounting sleeve 441 is provided at each end of the arc-shaped groove on the support base 44. A rotating shaft 45 is fixed to one side of the bottom of the bracket 41, located within the arc-shaped groove, with both ends of the shaft 45 rotatably mounted within the two mounting sleeves 441, allowing the bracket 41 to be rotatably mounted on the support base 44. A second rotary drive 46 is mounted on the support base 44, and its output end is connected to the rotating shaft 45, thereby driving the bracket 41 to rotate. The output end of the linear motion module 42 is specifically connected to the support base 44, and a second slider 43 is located at the bottom of the support base 44. Based on this configuration, the bracket 41 can be supported by the support base 44 after flipping, i.e., as... Figure 5 and Figure 6 As shown, the bracket 41 can be supported by the support base 44 in both horizontal and vertical positions to ensure the stability and reliability of the bracket 41 after it is flipped. The second rotary drive component 46 is specifically a motor.

[0045] The capping mechanism 6 includes a capper 61 and a second transfer module. The second transfer module drives the capper 61 to move closer to or further away from the headspace vial 5. Based on this configuration, when the bracket 41 is flipped into a vertical position, the capper 61 can be positioned further away from or offset from the headspace vial 5, facilitating the operator to drip the solution along the vial opening. Specifically, the capper 61 is an electric capper 61, with a display screen and operation buttons on its surface for the operator to perform corresponding operations. During capping, the operator can also hold the headspace vial 5 to ensure its stability.

[0046] In one embodiment, the second moving module is a single-axis moving module, such as a cylinder or a linear module, and the moving direction of the capping device 61 is vertical. Figure 5 and Figure 6 The X-axis direction from the perspective of view.

[0047] In another embodiment, the second moving module is a two-axis moving module used to drive the capping device 61 to move in both the vertical and horizontal directions, i.e. Figure 5 and Figure 6 The X-axis and Y-axis directions from a viewing angle. Specifically, the second moving module includes a second X-axis moving component 62 and a second Y-axis moving component 63. A third support frame 18 is also provided on one side of the base plate 1. The second Y-axis moving component 63 is mounted on the third support frame 18, and the second X-axis moving component 62 is mounted on the output end of the second Y-axis moving component 63. The capping device 61 is mounted on the output end of the second X-axis moving component 62. The second X-axis moving component 62 is used to drive the capping device 61 to move towards or away from the bottle neck of the headspace bottle 5. The second Y-axis moving component 63 is used to drive the capping device 61 to move horizontally, so that the capping device 61 is located above or offset from the bottle neck.

[0048] In the aforementioned two-axis moving module embodiment, the second X-axis moving component 62 and the second Y-axis moving component 63 are specifically cylinders or linear modules. In this embodiment, the third support 18 is also provided with a third slide rail 19, the length direction of the third slide rail 19 is in the same direction as the driving direction of the second Y-axis moving component 63, and the second X-axis moving component 62 is provided with a third slider, which slides in cooperation with the third slide rail 19.
