[0037] like Figure 1 As shown, this high-speed blister cartoning machine includes a material grid conveying device 3, a folding box material storehouse 1, a box suction transfer device 2, a box moving device 5 and a material pushing device 4. The material grid conveying device 3 and the box moving device 5 are arranged side by side, the material pushing device 4 is located on one side of the material grid conveying device 3, and the box suction transfer device 2 and the folding box material storehouse 1 are both located above the box moving device 5. The folding box material storehouse 1 is used to place a row of folding paper boxes (flat paper boxes) stacked sideways; the box suction transfer device 2 is used to suck the paper boxes from the folding box material storehouse 1, open them and transfer them to the box moving device 5; the box moving device 5 is used to convey the opened paper boxes; the material grid conveying device 3 is used to convey the blister plates; the material pushing device is used to push the blister plates on the material grid conveying device 3 into the paper boxes on the box moving device 5.

[0038] like Figure 2-Figure 6 As shown, the material pushing device includes a chain 41, a sprocket (not shown), an annular push plate guide 44, an annular paper pushing guide and a plurality of material pushing units 42. Each material pushing unit 42 includes a material pushing seat 420, a push plate assembly 421 and a paper pushing assembly 422. The push plate assembly 421 and the paper pushing assembly 422 are both mounted on the material pushing seat 420, and the material pushing seat 420 is connected to the chain 41, and the chain 41 is wound around the sprocket. Through the transmission of the main power source, the sprocket drives the chain 41 to rotate, and the chain 41 drives the material pushing unit 42 to make an annular motion. In order to reduce the load of the chain 41, the present invention is provided with annular guide rails 43 on both sides of the annular push plate guide 44, and both ends of the material pushing seat 420 are provided with a movable slide 423, and the movable slide 423 is arranged on the annular guide rail 43 in a sliding manner. The "sliding manner" here means that the movable slide 423 can make an annular motion on the annular guide rail 43. Through this structure, the weight of the entire pushing unit 42 acts on the annular guide rail 43. In other words, the annular guide rail 43 bears the weight of the entire pushing unit 42, and the chain 41 only needs to pull the entire pushing unit 42 to make a circular motion. Therefore, the noise of the entire system is significantly reduced, and the service life of the chain 41 is greatly extended.

[0039] There are two types of annular guide rail 43, and correspondingly, there are also two types of structures of movable slide seat 423. Two specific embodiments are given below.

[0040] The first type: the annular guide rail 43 can be in the form of a groove. In this case, the movable slide 423 can be only a roller, allowing a roller to roll in the annular groove. The groove is preferably located on the side, allowing the roller to enter the groove from the side. This structure can also enable the movable slide 423 to slide on the annular guide rail 43 to achieve the same technical effect.

[0041] The second type: the annular guide rail 43 is in a strip shape. In this case, the movable slide 423 includes an upper roller 4230 and a lower roller 4231. Figure 6 and 10 As shown, the lower roller 4231 and the upper roller 4230 hold the annular guide rail 43 inside and outside, that is, the lower roller 4231 acts on the inner ring of the annular guide rail 43, and the upper roller 4230 acts on the outer ring of the annular guide rail 43, so that the movable slide 423 will not move inside or outside; and the movable slide 423 at one end also includes a left roller and a right roller 4232, and the left roller and the right roller 4232 hold the annular guide rail 43 from left to right, that is, the left roller acts on the left side of the annular guide rail 43, and the right roller 4232 acts on the right side of the annular guide rail 43, so that the movable slide 423 will not move left to right. This structure can also make the movable slide 423 cooperate with the sliding arrangement on the annular guide rail 43 to achieve the same technical effect.

[0042] On the basis of the second annular guide rail 43, in order to improve the stability of the engagement between the movable slide 423 and the annular guide rail 43, the annular guide rail 43 of the present invention has two annular guide rails 43 arranged side by side, such as Fig. 9 The movable slide 423 has two upper rollers 4230 disposed front and rear, as shown Fig.10 As shown, the two upper rollers 4230 act on the two annular guide rails 43, one on the left and one on the right. Figure 6As shown, two upper rollers 4230 and one lower roller 4231 form a triangle when viewed from the side. The advantages of this structure of the movable slide 423 are: first, setting two upper rollers 4230 can increase the contact area between the movable slide 423 and the annular guide rail 43, so that the force borne by each upper roller 4230 can be shared, thereby reducing the friction between each upper roller 4230 and the annular guide rail 43, and finally reducing the system noise and improving the service life of the movable slide 423; second, the front and rear arrangement of the two upper rollers 4230 can make the movable slide 423 hug the annular guide rail 43 in the form of a triangle, and the three points form a surface, so that the movable slide 423 can more stably realize turning in the arc segment of the annular guide rail 43. Based on the movable slide 423 of the above structure, according to the conjugate cam principle, in order to enable the movable slide 423 to achieve smooth turning (i.e., in the turning section, the two upper rollers 4230 and the one lower roller 4231 are always in contact with the annular guide rail 43), the surfaces of the turning transition sections 430 of the two annular guide rails 43 have a height difference. Through this structure, the movable slide 423 always holds the annular guide rail 43 in the turning section, so that the motion trajectory of the center point of the movable slide 423 in the turning section is infinitely close to a semicircle, so that the motion trajectory of the pusher unit 42 is infinitely close to a runway type, and finally the pusher unit 42 is guaranteed to work stably.

[0043] As described above, the chain 41 pulls the pusher unit 42 to move. However, as time goes by, the chain 41 will be slowly stretched. As the chain 41 stretches, the chain 41 will not be able to push the pusher unit 42 to work normally. In order to solve this problem, Figure 7 As shown, the pusher seat 420 is connected to the chain 41 through the adaptive member 411, one end of the adaptive member 411 is hinged to the shaft pin 410 of the chain 41, and the other end of the adaptive member 411 is hinged to the pusher seat 420 (including direct hinge or indirect hinge, Figure 7 The middle picture shows that the chain 41 is hinged on a connecting seat, and the connecting seat is connected to the material pusher seat 420). The advantage of this structure is that even if the chain 41 has a certain stretch, since the material pusher seat 420 is restricted on the annular guide rail 43, the adaptive member 411 can be pulled by the material pusher seat 420, and the adaptive member 411 pulls the chain 41, thereby ensuring that the chain 41 can normally push the material pusher unit 42 to work, and finally ensuring that the push plate roller 444 will not fall off the annular push plate guide rail 44 when turning.

[0044] When the pusher device of the mainstream blister cartoning machine on the market changes specifications (the heights of blister plates of different specifications will be different), the height of the paper pusher for pushing the instruction manual must also change accordingly. The existing structure can only support the adjustment or replacement of a single paper pusher assembly 422 one by one, which is time-consuming and labor-intensive, and it is difficult to unify the adjustment height, which in turn affects the pushing of materials into the box.

[0045] In order to solve this problem, the present invention provides a guide slot frame 45 on the periphery of the annular push plate guide rail 44, such as 2 and Figure 3 As shown, the guide groove frame 45 is provided with an annular paper pushing guide groove 452 and an annular lifting guide groove 453. Fig.12 As shown, the guide slot frame 45 is assembled by an upper guide slot frame 450 and a lower guide slot frame 451, and the upper guide slot frame 450 is installed on the lower guide slot frame 451 in a manner that it can be raised and lowered. The upper guide slot frame 450 has an annular paper pushing guide slot upper section 4521 and an annular lifting guide slot upper section 4531, and the lower guide slot frame 451 has an annular paper pushing guide slot lower section 4522 and an annular lifting guide slot lower section 4532. The annular paper pushing guide slot upper section 4521 and the annular paper pushing guide slot lower section 4522 can be extended and connected, and the annular lifting guide slot upper section 4531 and the annular lifting guide slot lower section 4532 can be extended and connected: that is, when the upper guide slot frame 450 is raised and lowered, the distance between the annular paper pushing guide slot upper section 4521 and the annular paper pushing guide slot lower section 4522 changes, but the two still form a closed loop, and the same is true for the annular lifting guide slot upper section 4531 and the annular lifting guide slot lower section 4532.

[0046] After adopting the above-mentioned guide slot frame 45 structure, in order to enable the paper pushing assembly 422 to adapt to the guide slot frame 45, the structure of the pushing unit 42 should also be improved accordingly. The specific improvements are as follows: Fig.10 As shown, a lifting guide rail 424 is installed on the pusher seat 420. Fig.11 As shown, a positioning slider 425 is slidably provided on the lifting guide rail 424, and a lifting roller 426 and a positioning guide groove 427 are installed on the positioning slider 425, and the lifting roller 426 is arranged in the annular lifting guide groove 453; the paper pushing assembly 422 includes a paper pushing paperboard 4220 and a paper pushing guide rod 4221, one end of the paper pushing guide rod 4221 is connected to the paper pushing paperboard 4220, and the other end of the paper pushing guide rod 4221 is connected to the paper pushing roller 4222, and the paper pushing guide rod 4221 is arranged in the positioning guide groove 427, and the positioning guide groove 427 guides the paper pushing guide rod 4221, and the paper pushing roller 4222 is arranged in the annular paper pushing guide groove 452.

[0047] The height adjustment principle of the push paper board 4220 is as follows: when the height of the medicine board increases, the height of the push paper board 4220 also increases accordingly. When adjusting, the upper guide slot frame 450 is raised, and the annular paper push guide slot upper section 4521 and the annular lifting guide slot upper section 4531 are raised at the same time. Since the lifting roller 426 is in the annular lifting guide slot 453, the positioning slider 425 moves and rises on the lifting guide rail 424, and the positioning guide slot 427 is also raised at the same time. Since the paper push roller 4222 is set in the annular paper push guide slot 452, the paper push guide rod 4221 and the push paper board 4220 are also raised at the same time. In this way, the paper push guide rod 4221 is still in the positioning guide slot 427, and the push paper board 4220 can adapt to the height of the medicine board after being raised. In this way, it is very simple to adjust the height of the push paper board 4220, as long as the height of the upper guide slot frame 450 is adjusted, thereby reducing the difficulty of adjusting the equipment after changing the specifications of the medicine board and improving production efficiency.

[0048] The extendable connection between the upper section 4521 of the annular paper pushing guide groove and the lower section 4522 of the annular paper pushing guide groove can adopt a variety of structures, such as a stretchable extension guide groove, which is used to connect the upper and lower sections. The present invention provides a more convenient connection method: Fig.12 As shown, the end of the annular paper pushing guide groove upper section 4521 has a vertical guide groove extension 454, and the end of the annular paper pushing guide groove lower section 4522 has a vertical connection adjustment groove 455, and the guide groove extension 454 is arranged in a lifting manner in the connection adjustment groove 455. When the height of the upper guide groove frame 450 is adjusted, the guide groove extension 454 on the upper guide groove frame 450 moves vertically up and down in the connection adjustment groove 455 on the lower guide groove frame 451, while the annular paper pushing guide groove 452 is still a closed guide groove.

[0049] Similarly, the extendable connection between the upper section 4531 of the annular lifting guide groove and the lower section 4532 of the annular lifting guide groove can adopt a variety of structures. Since the annular lifting guide groove 453 is slotted along the horizontal direction, an extension block that can move up and down can be used on the side to connect the upper and lower sections through the extension block; the present invention provides a more convenient connection method: Fig.12 and Fig.13 As shown, the end of the annular lifting guide groove upper section 4531 has a vertical upper guide groove side wall 4533, and the end of the annular lifting guide groove lower section 4532 has a vertical lower guide groove side wall 4534, and the lower guide groove side wall 4534 is aligned with the upper guide groove side wall 4533. When the height of the upper guide groove frame 450 is adjusted, although the upper guide groove side wall 4533 on the upper guide groove frame 450 and the lower guide groove side wall 4534 on the lower guide groove frame 451 are changed in vertical distance, the two are still attached together, and the lifting roller can still be on the upper guide groove side wall 4533 or the lower guide groove side wall 4534, that is, the annular lifting guide groove 453 is still a closed guide groove.

[0050] In order to more stably adjust the position of the upper guide slot frame 450, the present invention installs a lifting slider seat 4511 on the lower guide slot frame 451, the upper guide slot frame 450 is installed with a linear guide rail 4501, and the lifting slider seat 4511 is slidably arranged on the linear guide rail 4501, and an adjusting screw 458 is also installed on the lower guide slot frame 451, and the adjusting screw 458 is threadedly connected with the upper guide slot frame 450. When the position of the upper guide slot frame 450 needs to be adjusted, the upper guide slot frame 450 can be moved up and down through the linear guide rail 4501 by rotating the adjusting screw 458 (either manually or by a motor), thereby achieving smooth adjustment.

[0051] Of course, the push plate assembly 421 includes a push plate head 4210, a push plate roller 4212 and a push plate slider 4211. Fig.10 As shown, the push plate roller 4212 and the push plate head 4210 are both connected to the push plate slider 4211, the push plate roller 4212 is located in the annular push plate guide rail 44, the push plate seat 420 is provided with a positioning guide rail 428, and the push plate slider 4211 is slidably arranged on the positioning guide rail 428. As the push plate seat 420 makes an annular motion, the push plate roller 4212 moves on the annular push plate guide rail 44, and under the guidance of the annular push plate guide rail 44, the push plate slider 4211 moves on the positioning guide rail 428, so that the push plate head 4210 realizes the action of pushing the medicine plate.

[0052] This pushing device is provided with annular guide rails 43 on both sides of the annular push plate guide rail 44, and the movable slides 423 at both ends of the pushing seat 420 are slidably arranged on the annular guide rails 43, so that the annular guide rails 43 bear the weight of the entire pushing unit 42, and the chain 41 is only responsible for pulling the entire pushing unit 42 to move, so that the noise of the entire system is greatly reduced and the service life of the chain is extended.

[0053] like Fig.14 As shown, the box suction transfer device 2 is installed between the folding box material warehouse 1 and the box conveying device 5. Its function is to transfer the folding paper boxes C (or flat paper boxes) in the folding box material warehouse 1 to the box conveying device 5 below, and the box conveying device 5 transports the paper boxes to the next station.

[0054] like Fig.15As shown, the suction box transfer device includes a mounting base 21, a power source 22, a main shaft 219, a central fixed gear 23, a revolving disk 24 and a plurality of suction nozzle rod assemblies 26, the main shaft 219 is mounted on the mounting base 21, the revolving disk 24 is mounted on the main shaft 219 through a bearing, and the central fixed gear 23 is fixedly mounted on the main shaft 219; the suction nozzle rod assembly 26 includes a suction box nozzle 260 and a suction box rod 261, the suction box rod 261 of each suction nozzle rod assembly 26 is eccentrically mounted on a rotating disk 218, and the rotating disk 218 is rotatably mounted on the revolving disk 24 through a rotating shaft, a planetary gear 28 is mounted on the rotating shaft (the rotating shaft is not shown in the figure), and a transition gear 27 is rotatably mounted on the revolving disk 24, the planetary gear 28 is meshed with the transition gear 27, and the transition gear 27 is meshed with the central fixed gear 23. A transmission wheel 25 is rotatably mounted on the main shaft 218, and the transmission wheel 25 is connected to the revolving disk 24. The transmission wheel 25 is driven to rotate by the power source 22, and the revolving disk 24 rotates. Since the self-rotating disk 218 is rotatably mounted on the revolving disk 24 through the rotation axis, and the suction box rod 261 of each suction nozzle rod assembly 26 is mounted on a self-rotating disk 218, the self-rotating disk 218 and the suction nozzle rod assembly 26 realize orbital rotation with the revolving disk 24; since a planetary gear 28 is mounted on the rotation axis, and the planetary gear 28 is meshed with the transition gear 27, and the transition gear 27 is meshed with the central fixed gear 23, the suction nozzle rod assembly 26 and the self-rotating disk 218 realize self-rotation with the revolution of the self-rotating disk 218, and since the suction box rod 261 is eccentrically mounted on the self-rotating disk 218, the suction box nozzle 260 forms the following in the whole movement process. Fig.14 The motion trajectory shown in FIG. 2 allows the box suction nozzle 260 to be sucked onto the paper box in a manner that the oblique angle gradually turns positive (such as Fig.16 As shown in the figure, the process of the box suction nozzle 260 being adsorbed on the flat paper box is prolonged, so that the adsorption force is stronger, the paper box is less likely to fall, and the box feeding rate of the high-speed blister cartoning machine can be met.

[0055] In order to allow the carton to be opened during the transportation process, the present invention installs an outer plate 213 on the mounting seat 21, and a suction component is installed on the outer plate 213, such as Fig.14 As shown, the suction assembly includes a suction nozzle 215 and a suction rod 214. A first box stopper 216 is installed on one side of the suction nozzle 215. A second box stopper 217 is provided between the first box stopper 216 and the axis of the main shaft. When the folded paper box is sucked down and rotated at a certain angle to the position of the suction assembly, the suction nozzle 215 of the suction assembly sucks the paper box, so that the paper box is slightly opened. Then, the paper box is successively opened by the first box stopper 216 and the second box stopper 217 during the descent process. When it reaches the bottom, the paper box is completely opened to form a three-dimensional paper box that falls into the box feeding device 5 below.

[0056] Finally, it is worth mentioning that the second baffle member 217 of the present invention has a side facing the first baffle member 216 which is an arc surface. Since the movement trajectory of the suction nozzle 260 has a certain curvature, the arc surface of the second baffle member 217 can cater to the movement trajectory of the suction nozzle 260, thereby making the paper box more stable and smooth to open.

[0057] like Fig.17 and 19 As shown, the box feeding device 5 includes a base (not shown), a support 52, a left main chain, a right main chain and a driving spline shaft 51. The left main chain is wound around a left main sprocket 56, and the right main chain is wound around a right main sprocket 53. The left main chain and the right main chain are both connected to the support 52. Fig.17 As shown, the support member 52 has a base portion and a stopper portion, the stopper portion is located on the base portion, and the base portion is connected to the pin of the chain. It is worth mentioning that in the present invention, the names with "left", "right", "primary" or "secondary" are only used for distinction and do not play a limiting role.

[0058] like Fig.18 As shown, the right main sprocket 53 is arranged on the active spline shaft 51 through the right spline sleeve, and the right spline sleeve is provided with a right rotating sleeve (not shown) outside the movable sleeve, and the right rotating sleeve is connected to the right active pulley 55 and the right secondary sprocket 54, and the right secondary chain is wound around the right secondary sprocket 54, and the right secondary chain is connected to the support member 52, and the right secondary chain is parallel to the right main chain.

[0059] like Fig.17 As shown, as long as the right main sprocket 53 remains stationary and the right secondary sprocket 54 rotates, the support member 52 on the right main sprocket 53 and the support member 52 on the right secondary chain will be staggered, so that as long as the right secondary chain is rotated, the spacing suitable for different box widths can be adjusted. Of course, the maximum box width is the distance between two adjacent support members 52 on the same chain (minus the width of the upper end of the support member 52). Here, the principle of adjusting the box width on the right is simply explained, and the adjustment method on the left is the same. Through the synchronous adjustment of the left and right sides, the spacing adjustment that can adapt to different box widths is finally achieved. The transmission structure is first introduced below, and then the adjustment principle that can adapt to different box widths and box lengths is explained in detail.

[0060] like Fig.18As shown, the left main sprocket 56 is connected to the active spline shaft 51 through the left circular sleeve (the left main sprocket 56 is fixed to the active spline shaft 51 because it does not move left and right), the left circular sleeve is provided with a left rotating sleeve, the left rotating sleeve is connected with a left active pulley 58 and a left secondary sprocket 57, the left secondary sprocket 57 is located between the left main sprocket 56 and the left active pulley 58, the left secondary sprocket 57 is wound with a left secondary chain, and the left secondary chain is connected with a support member 52, the left secondary chain is parallel to the left main chain. As with the above adjustment principle, as long as the left main sprocket 56 is kept stationary and the left secondary sprocket 57 is rotated, the support member 52 on the left main sprocket 56 and the support member 52 on the left secondary chain will be staggered.

[0061] The left and right sides must be adjusted synchronously. For this purpose, a driven spline shaft 511 is installed on one side of the driving spline shaft 51. The right end of the driven spline shaft 511 is sleeved with a right driven pulley 512 with a spline hole (that is, the spline hole of the right driven pulley 512 is sleeved on the driven spline shaft 511, and the right driven pulley 512 can move axially on the driven spline shaft 511). The right driven pulley 512 and the right driving pulley 55 are wound with a right transmission belt 517. The left end of the driven spline shaft 511 is connected to a left driven pulley 513 and an outer driven pulley 514. The left driven pulley 513 and the left driving pulley 58 are wound with a left transmission belt 518. In addition, as Fig.17 and Fig.19 As shown, a sliding seat 521 which can be moved up and down and adjusted is provided on the machine base, and an upper moving wheel 515 and a lower moving wheel 516 are installed on the sliding seat 521, and an external driving pulley 59 is connected to the driving spline shaft 51 (the external driving pulley 59 can be connected to the left circular sleeve), and an external transmission belt 519 is wound around the external driving pulley 59, the external driven pulley 514, the upper moving wheel 515 and the lower moving wheel 516.

[0062] The transmission principle of the box-moving device when working is as follows: the motor 522 drives the active spline shaft 51 to move actively. Since the right main sprocket 53 is arranged on the active spline shaft 51 through the right spline sleeve, and the left main sprocket 56 is connected to the active spline shaft 51 through the left round sleeve, the right main sprocket 53 and the left main sprocket 56 rotate synchronously; since the outer driving pulley 59 is connected to the active spline shaft 51, the outer driving pulley 59 also rotates synchronously, and the outer driving pulley 59 drives the outer driven pulley 514 to rotate through the outer transmission belt 519, and since the outer driven pulley 514 is connected to the driven spline shaft 511, the driven spline shaft 511 rotates synchronously; since the right end of the driven spline shaft 511 is connected to the right driven pulley 512, the right driven pulley The driven pulley 512 rotates synchronously, and the right driven pulley 512 drives the right driving pulley 55 to rotate through the right transmission belt 517. Since the right driving pulley 55 and the right secondary sprocket 54 are connected to the right rotating sleeve, and the right rotating sleeve is rotatably sleeved on the right spline sleeve, the right driving pulley 55 and the right secondary chain rotate synchronously; since the left end of the driven spline shaft 511 is connected with the left driven pulley 513, the left driven pulley 513 rotates synchronously, and the left driven pulley 513 drives the left driving pulley 58 to rotate through the left transmission belt 518. Since the left driving pulley 58 and the left secondary chain are connected to the left rotating sleeve, and the left rotating sleeve is movably sleeved on the left circular sleeve, the left driving pulley 58 and the left secondary sprocket 57 rotate synchronously. Through the above transmission structure, the output of the motor 522 can synchronously drive the right main sprocket 53, the right secondary sprocket 54, the left main sprocket 56 and the left secondary sprocket 57 to rotate synchronously.

[0063] The adjustment principle of this box feeding device to adapt to different box length specifications is as follows: the motor 522 stops outputting, and since the right main sprocket 53, the right secondary sprocket 54, and the right driving pulley 55 can move axially on the driving spline shaft 51, and the right driven pulley 512 can move axially on the driven spline shaft 511, the distance between the left and right support members 52 can be adjusted by axially moving the right main sprocket 53, the right secondary sprocket 54, the right driving pulley 55 and the right driven pulley 512.

[0064] The adjustment principle of this box feeding device to adapt to different box width specifications is as follows: during adjustment, the motor 522 stops output, the active spline shaft 51 does not move, the right main sprocket 53 and the left main sprocket 56 do not move, and the upper moving wheel 515 and the lower moving wheel 516 are moved up and down together by moving the sliding seat 521. Since the outer active pulley 59 is fixed, the outer driven pulley 514 rotates, and the right driven pulley 512 and the left driven pulley 513 rotate synchronously, which also drives the right active pulley 55 and the left active pulley 58 to rotate synchronously, so that the right auxiliary sprocket 54 and the left auxiliary sprocket 57 have an angular velocity change relative to the right main sprocket 53 and the left main sprocket 56, thereby achieving adjustment to adapt to different box width specifications.

[0065] In order to make the external transmission belt 519 more tightly and fully attached to the external driving pulley 59, the external driven pulley 514, the upper moving wheel 515 and the lower moving wheel 516, the present invention provides auxiliary wheels 520 between the upper moving wheel 515 and the external driving pulley 59, between the upper moving wheel 515 and the external driven pulley 514, between the lower moving wheel 516 and the external driving pulley 59, and between the lower moving wheel 516 and the external driven pulley 514. The four auxiliary wheels 520 are all pressed onto the external transmission belt 519 from the outside.

[0066] The sliding seat 521 can be adjusted manually to move up and down, or can be adjusted by the motor 522. In order to facilitate the adjustment, the present invention is provided with an adjustment motor 522 on the base, and the adjustment motor 522 is connected to the screw rod, and the screw rod is threadedly connected to the sliding seat 521. The screw rod is driven by the adjustment motor 522 to rotate, and the screw rod drives the sliding seat 521 to move up and down, thereby driving the upper moving wheel 515 and the lower moving wheel 516 to move up and down.
