Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to cup holder assembly equipment and a cup holder assembly method. Background Art

[0002] The existing production process for cup products, such as yogurt cups, requires placing one or more cup bodies on a cup holder before packaging. Currently, placing the cup body on the cup holder is primarily accomplished by using a robotic arm to grasp and place the cup and paper holder together to form a connected cup and paper holder product for the next process. This robotic arm often requires multiple servo motor and reducer combinations, along with corresponding robotic arm linkages to drive the manipulator's movement. This places high demands on the manipulator's positioning, resulting in a complex structure and difficult maintenance for existing cup holder assembly equipment. The robotic arm's reciprocating motion to grasp the cup body results in low assembly efficiency. In situations where high speed is required, several additional robotic arms are needed to meet production requirements, resulting in high production costs. Summary of the Invention

[0047] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 3 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The left and right directions are consistent with the Figure 1 The up and down directions themselves are consistent.

[0049] like Figures 1 to 8 As shown, this embodiment provides a cup holder assembly device, comprising a cup holder conveying mechanism 1, a cup body conveying mechanism 2, and a cup separating mechanism 3. The cup holder conveying mechanism 1 has a cup holder conveying channel 101 for conveying the cup holder. The cup body conveying mechanism 2 has a cup body conveying channel 201 for conveying the cup body 7. Both the cup holder conveying channel 101 and the cup body conveying channel 201 extend from front to back. The cup holder and the cup body 7 are conveyed from front to back.

[0050] The cup conveying channel 201 has an upper cup end 203 and a lower cup end 204. The upper cup end 203 is located near the front end of the cup conveying channel 201, and the lower cup end 204 is located at the rear end of the upper cup end 203. The lower cup end 204 of the cup conveying channel 201 is connected to the cup holder conveying channel 101. When the cup holder conveying channel 101 conveys a cup holder, the cup body 7 falls from the lower cup end 204 of the cup conveying channel 201 onto the cup holder in the cup holder conveying channel 101, completing assembly.

[0051] The cup-dispensing mechanism 3 includes a cup-dispensing rack 301 and a cup-dispensing turntable 302 rotatably mounted on the rack 301. The cup-dispensing turntable 302 is provided with a plurality of partition plates 303 spaced circumferentially along the rotation axis of the cup-dispensing turntable 302. The partition plates 303 are integrally formed with the cup-dispensing turntable 302. The partition plates 303 are provided with grouping spaces 304 for accommodating a plurality of cup bodies 7. Each grouping space 304 accommodates at least one cup body 7. In this embodiment, the grouping spaces 304 accommodate at least two or more cup bodies 7.

[0052] The cup conveying channel 201 is located on the rotation path of the partition plate 303. When the cup dividing turntable 302 rotates, it can drive the partition plate 303 toward or away from the cup conveying channel 201. When the partition plate 303 enters the cup conveying channel 201, it can push the multiple cup bodies 7 on the cup conveying channel 201 into the grouping space 304, so that the cup bodies 7 in the cup conveying channel 201 are divided into product groups having multiple cup bodies 7, each of which is located in a grouping space 304. Finally, the product group in each grouping space 304 of the partition plate 303 is pushed from the lower cup end 204 of the cup conveying channel 201 to the cup tray of the cup tray conveying channel 101, completing the assembly of the cup body and the multiple cup bodies 7, facilitating subsequent packaging. Existing equipment generally groups the cup bodies 7 manually and then uses a robot to grab them back and forth. The grabbing action of the robot is dangerous. Improper operation may cause harm to the production operator who groups the cup bodies 7. This application uses the cup-classifying turntable 302 and the partition plate 303 on the cup-classifying turntable 302 to achieve the grouping and transportation of the cup bodies 7. No manual participation is required, which reduces the risk of production.

[0053] In one embodiment, the cup dispensing mechanism 3 further includes a cup sorting turntable 305 rotatably mounted on the cup dispensing rack 301. The cup sorting turntable 305 is equipped with a plurality of arranging plates 306 evenly spaced along the circumference of the cup sorting turntable 305's rotation axis. The cup sorting turntable 305 and the arranging plates 306 are integrally formed, and the cup dispensing turntable 302 and the cup sorting turntable 305 together form a planetary gear structure. An arranging space 307 for accommodating a single cup body 7 is formed between any two adjacent arranging plates 306. The inner wall of the arranging space 307 is semicircular and accommodates only a single cup body 7. The cup conveying channel 201 is located on the rotation path of the sorting plate 306. When the cup sorting turntable 305 rotates, it can drive the sorting plate 306 to approach or move away from the cup conveying channel 201. When the sorting plate 306 approaches the cup conveying channel 201, the sorting plate 306 can sort the cup bodies 7 on the cup conveying channel 201 into an equidistant distribution and then push them to the grouping space 304. The cup bodies 7 arranged and transported in sequence on the cup conveying channel 201 enter the sorting space 307 respectively, so that the cup bodies 7 on the cup conveying channel 201 are evenly spaced before entering the grouping space 304, which facilitates grouping in the grouping space 304 and improves the cup separation efficiency of the cup separation turntable 302. In this way, the cup separation mechanism 3 of the present application can arrange the cup bodies 7 arranged in sequence on the cup conveying channel 201 into a uniformly spaced arrangement through the cup sorting turntable 305 and the sorting plate 306 and send them to the cup separation turntable 302. Then the cup separation turntable 302 uses the grouping space 304 on the partition plate 303 to separate the cup bodies 7 into multiple product groups, realizing automatic transportation, sorting and grouping of the cup bodies 7, thereby improving the degree of automation and production efficiency.

[0054] In one embodiment, the cup separation turntable 302 and the cup sorting turntable 305 are arranged in sequence along the conveying path of the cup conveying channel 201. The cup sorting turntable 305 and the cup separation turntable 302 are arranged at intervals from front to back. A feeding space 308 for the cup conveying channel 201 to pass through is formed between the cup separation turntable 302 and the cup sorting turntable 305. Part of the cup conveying channel 201 passes through the feeding space 308 along an S track, reducing the length of the cup conveying channel 201 in the front-to-back direction, facilitating the installation and positioning of the cup sorting turntable 305 and the cup separation turntable 302, so that the cup body 7 can be easily removed from the cup sorting channel 201. The cup body 7 can directly enter the grouping space 304 in the process of coming out of the sorting space 307, that is, a part of the cup body 7 can directly enter the grouping space 304 after coming out of the sorting space 307. The sorting space 307 and the grouping space 304 are precisely matched to avoid the cup body 7 from being unable to enter the grouping space 304 due to position changes caused by equipment vibration after coming out of the sorting space 307. In this way, the present application can drive the cup sorting turntable 305 and the cup dividing turntable 302 to rotate in opposite directions, so that the cup body 7 can pass through the cup sorting turntable 305 and the cup dividing turntable 302 in turn.

[0055] Furthermore, there may be multiple cup-collecting turntables 302 and / or cup-organizing turntables 305. In this embodiment, there are two cup-collecting turntables 302 and one cup-organizing turntable 305. The cup bodies 7 first pass through the cup-organizing turntable 305 and then sequentially pass through the two cup-collecting turntables 302. A feeding space 308 is formed between the cup-organizing turntable 305 and the adjacent cup-collecting turntable 302. In this way, the cup bodies 7 are grouped by passing through multiple cup-collecting turntables 302, improving grouping accuracy.

[0056] In other embodiments, the number of groups of the cup bodies 7 divided by the multiple cup dividing turntables 302 may be different. For example, the first cup dividing turntable 302 divides six cup bodies 7 into one group, and then the next cup dividing turntable 302 divides the six cup bodies 7 of the previous group into three groups, thereby further improving the accuracy of the grouping of the cup bodies 7.

[0057] In one embodiment, the cup holder conveying mechanism 1 includes a cup holder 102 and a first feed belt mounted on the cup holder 102. The cup holder conveying channel 101 is located on the first feed belt. The cup body conveying mechanism 2 includes a cup body holder 202 and a second feed belt mounted on the cup body holder 202. The cup body conveying channel 201 has a guide section 206 extending along an S-shaped trajectory and a power section 205 located on the second feed belt. The guide section 206 is provided on the cup holder 102 and is a non-powered channel made of sheet metal. A sorting plate 306 and a partition plate 303 are provided above the guide section 206, and the cup holder conveying channel 101 is located below the guide section 206. The upper cup end 203 is located at the front end of the second feed belt, with the rear end of the second feed belt aligned with the front end of the guide section 206. The lower cup end 204 is located at the rear end of the guide section 206. After the cup body 7 enters the guide section 206 from the power section 205, the cup body 7 on the guide section 206 is pushed by the rotation of the sorting plate 306 and the partition plate 303. Both the first and second feed belts extend from front to back. The cup holder and cup body 7 are both conveyed from front to back.

[0058] Furthermore, the outer side of the partition plate 303 has a convex arc portion 314, a first concave arc portion 315, and a second concave arc portion 316, which are connected in sequence. A boss 317 is formed between the first and second concave arc portions 315, 316. The cup conveying channel 201 is located in the rotation path of the boss 317. As a result, when the partition plate 303 rotates with the cup-distributing turntable 302, the boss 317 engages between adjacent cup bodies 7, separating the cup bodies 7 and grouping them. When the boss 317 is inserted between adjacent cup bodies 7, the first and second concave arc portions 315, 316 guide the cup bodies 7 of the preceding product group and the cup bodies 7 of the succeeding product group. The separated cup bodies 7 are separated under the guidance of the first and second concave arc portions 315, 316, respectively. As the cup-dispensing turntable 302 rotates, the first concave arc portion 315 on one side of the boss 317 pushes the cup bodies 7 of the preceding product group to be arranged sequentially on the convex arc portion 314 and the first concave arc portion 315. The second concave arc portion 316 on the other side of the boss 317 blocks the cup bodies 7 of the succeeding product group, forcing them to wait for the boss 317 on the next dividing plate 303 to push them. The convex arc portion 314 facilitates guiding the cup bodies 7 of the product group along an S-shaped trajectory, allowing them to land sequentially on the cup holder conveying channel 101, which extends along a straight trajectory.

[0059] In one embodiment, the cup-dispensing mechanism 3 further includes a driver 309 mounted on the cup-dispensing rack 301. The cup-dispensing turntable 302 and the cup-handling turntable 305 are both in transmission connection with the driver 309. Specifically, the driver 309 includes a first motor 311, a second motor 312, and a third motor 313. The first motor 311 is in transmission connection with the cup-handling turntable 305 via a first reducer 418 and a first co-conveyor belt assembly. The second motor 312 is in transmission connection with one of the cup-dispensing turntables 302 via a second reducer 418 and a second co-conveyor belt assembly. The third motor 313 is in transmission connection with the other of the cup-dispensing turntables 302 via a third reducer 418 and a coupling. A first rotating shaft is mounted on the cup-dispensing rack 301. One end of the first rotating shaft is connected to the cup-handling turntable 305 and is equipped with a tensioning outer sleeve and a tensioning inner sleeve. The other end of the first rotating shaft is equipped with a bearing and a skeleton oil seal and is in transmission connection with the first motor 311.

[0060] Optionally, the cup-dispensing mechanism 3 further includes an origin detection module 310. The origin detection module 310 is used to detect the origins of the cup-dispensing turntable 302 and the cup-organizing turntable 305. Specifically, the cup-dispensing turntable 302 is mounted to the cup-dispensing rack 301 via a second rotating shaft, and both the first rotating shaft and the second rotating shaft are mounted with the origin detection module 310.

[0061] In one embodiment, the cup holder conveying mechanism 1 further includes a first folding paper sheet and a second folding paper sheet. The first and second folding paper sheets are spaced apart along the width of the cup holder conveying passage 101, with at least a portion of the cup holder conveying passage 101 located between the first and second folding paper sheets. The cup holder is a piece of paper. When placed in the cup holder conveying passage 101, its sides fold upward to form protective edges, restrained by the first and second folding paper sheets.

[0062] In one embodiment, the cup holder assembly apparatus further includes a paper separator 4. The paper separator 4 includes a movable suction assembly. The cup holder conveying channel 101 is located along the suction assembly's moving path. Specifically, the suction assembly comprises two groups: a first suction assembly 404 and a second suction assembly 405. The first and second suction assemblies 404, 405 alternately suction and convey the cup holder to the cup holder conveying channel 101.

[0063] In one embodiment, the cup holder assembly apparatus further includes a paper feed mechanism 5 having a paper feed passage. The paper feed passage is located along the path of movement of the suction assembly. The paper feed passage of the paper feed mechanism 5 is used to store the cup holders, and the paper separation mechanism 4 is used to transfer the cup holders from the paper feed passage to the cup holder conveying passage 101.

[0064] Furthermore, the paper separation mechanism 4 includes a base 401, a rotating base 402 rotatably mounted on the base 401, a paper pickup base 403 rotatably mounted on the rotating base 402, a first suction assembly 404, a second suction assembly 405, and a fourth motor 406. The rotating base 402 is arranged such that the rotation axis of the rotating base 402 and the rotation axis of the paper pickup base 403 are spaced apart and parallel to each other, and the paper pickup base 403 is mounted eccentrically. The rotation axis of the rotating base 402 is horizontally disposed, and the rotation axis of the paper pickup base 403 is horizontally disposed, and the rotation axis of the paper pickup base 403 rotates around the rotation axis of the rotating base 402. The fourth motor 406 is directly or indirectly connected to the rotating seat 402 and the paper picking seat 403, so that the rotating seat 402 and the paper picking seat 403 rotate respectively. The fourth motor 406 can be one that drives the rotating seat 402 and the paper picking seat 403 to rotate at the same time, or two fourth motors 406 can drive the rotating seat 402 and the paper picking seat 403 to rotate respectively. In this embodiment, a fourth motor 406 is used to simultaneously drive the rotating seat 402 and the paper picking seat 403 to rotate, which not only saves costs and reduces the volume of the paper separating mechanism 4, but also allows the rotating seat 402 and the paper picking seat 403 to rotate or stop at the same time, ensuring the rotation coordination of the rotating seat 402 and the paper picking seat 403.

[0065] The first suction component 404 and the second suction component 405 can both be used to absorb the cup holder, which is generally a piece of paper or a paper holder. In this embodiment, the cup holder is a piece of paper, and the cup holder has a paper surface to be sucked. The first suction component 404 and the second suction component 405 are arranged on the paper pick-up seat 403 at intervals along the circumference of the rotation axis of the paper pick-up seat 403. The first suction component 404 and the second suction component 405 each have one, and the first suction component 404 and the second suction component 405 are distributed at 180 degrees. The first suction component 404 and the second suction component 405 are mirror-symmetrical. Since the paper pick-up seat 403 is eccentrically installed, the first suction component 404 and the second suction component 405 can be closer to the paper feeding channel when sucking the cup holder and closer to the production line for cup holder packaging when transporting and placing the cup holder. The paper feed channel is located along the moving path of the first suction assembly 404 and the second suction assembly 405. A fourth motor 406 is in transmission connection with the rotating base 402 and the paper pickup base 403 to drive the first suction assembly 404 and the second suction assembly 405 to alternately move toward and away from the paper feed channel. When the first suction assembly 404 approaches the paper feed channel, the second suction assembly 405 moves away from the paper feed channel. When the first suction assembly 404 moves away from the paper feed channel, the second suction assembly 405 moves toward the paper feed channel. The fourth motor 406 drives the rotating base 402 and the paper pickup base 403 to rotate, causing the first suction assembly 404 and the second suction assembly 405 to alternately move toward the paper feed channel, allowing the first suction assembly 404 and the second suction assembly 405 to alternately pick up the cup holder from the paper feed channel and transport it to a designated location.

[0066] When the cup holder conveying device is in operation, the paper feeding mechanism 5 first feeds the cup holder along the paper feeding path. The paper separating mechanism 4 is then activated, and the fourth motor 406 drives the rotating base 402 to rotate, thereby driving the eccentrically mounted paper pickup base 403 on the rotating base 402 and the first and second suction assemblies 404, 405 on the paper pickup base 403 to alternately approach the paper feeding path. This allows the first and second suction assemblies 404, 405 to alternately absorb the cup holder from the paper feeding path. Because the paper pickup base 403 can rotate relative to the rotating base 402, i.e., the paper pickup base 403 can rotate driven by the rotating base 402 or rotate on its own, both the first and second suction assemblies 404, 405 can absorb the cup holder in a direction perpendicular to the paper surface of the cup holder. This ensures that the first and second suction assemblies 404, 405 are perpendicular to the paper surface of the cup holder when they pick up the cup holder. This allows the first and second suction assemblies 404, 405 to place the cup holder vertically on the production line. Exemplarily, the paper feed channel is located above the paper separator 4, and the production line for packaging cup holders is located below the paper separator 4. The cup holders are tilted downward with their paper patterned surfaces facing downward. Driven by the rotating base 402, the first suction assembly 404 and the second suction assembly 405 alternately approach the paper feed channel and absorb the cup holders. Driven by the paper pick-up base 403, the first suction assembly 404 and the second suction assembly 405 rotate, causing the first suction assembly 404 and the second suction assembly 405 to absorb the cup holders in a direction perpendicular to the paper patterned surfaces of the cup holders. After the first suction assembly 404 and the second suction assembly 405 absorb the cup holders, they alternately approach the production line and place the cup holders on the production line from top to bottom, facilitating packaging of the cup holders and cup bodies together on the production line. By driving the rotating base 402 to rotate, the first suction component 404 sucks the cup holder upward while the second suction component 405 places the cup holder downward on the production line. The first suction component 404 sucks the cup holder upward while the second suction component 405 places the cup holder downward on the production line. When the first suction component 404 places the cup holder on the production line, the second suction component 405 is on a moving path close to the paper feeding channel. When the second suction component 405 places the cup holder on the production line, the first suction component 404 is on a moving path close to the paper feeding channel, thereby realizing continuous conveyance of the cup holders, improving the conveyance efficiency of the cup holders, and thereby improving the production efficiency of cup products.

[0067] In one embodiment, the paper separation mechanism 4 further includes a first driving wheel 407 rotatably mounted on the base 401, a first driven wheel 408 rotatably mounted on the rotating base 402, and a first transmission belt 409 sleeved around the first driving wheel 407 and the first driven wheel 408. A first tensioning wheel 420 is mounted on the base 401 to tension the first transmission belt 409. The fourth motor 406 is in transmission connection with the first driving wheel 407 via a reducer 418, and the first driven wheel 408 is in transmission connection with the paper pickup base 403. The first driven wheel 408 has a larger diameter than the first driving wheel 407. The fourth motor 406 drives the first driving wheel 407 and the first driven wheel 408 to rotate, thereby driving the paper pickup base 403 to rotate.

[0068] Optionally, a position sensor 421 is mounted on the base 401. The position sensor 421 is used to detect the position of the rotating base 402, thereby facilitating the fourth motor 406 to control the rotating base 402 to rotate, thereby accurately controlling the first suction component 404 and the second suction component 405 to alternately suck the cup holder.

[0069] Optionally, the paper separation mechanism 4 further includes a counterweight 410 provided on the rotating seat 402. The counterweight 410 and the paper pickup seat 403 are arranged at intervals along the radial direction of the first driven wheel 408, and the rotation axis of the rotating seat 402 is located between the counterweight 410 and the axis of the paper pickup seat 403. The projection of the rotating seat 402 along the rotation axis is elliptical or runway-shaped. The paper pickup seat 403 is mounted on the end face of the rotating seat 402 and close to one of the outer arc surfaces. The counterweight 410 is sleeved on the other outer arc surface of the paper pickup seat 403. Since the paper pickup seat 403 is eccentrically mounted on the rotating seat 402, the counterweight 410 is provided on the rotating seat 402. The counterweight 410 is used to balance the weight of the paper pickup seat 403 and the first suction assembly 404 and the second suction assembly 405, making the rotation of the rotating seat 402 more stable and improving the life of the rotating seat 402 and the wheel axle.

[0070] In one embodiment, the first suction assembly 404 includes a plurality of first suction elements 411. The second suction assembly 405 includes a plurality of second suction elements 412. The first suction elements 411 and the second suction elements 412 are suction cups or nozzles. The paper pickup seat 403 has a first mounting surface 413 and a second mounting surface 414 that face away from each other. The plurality of first suction elements 411 are spaced apart on the first mounting surface 413, and the plurality of second suction elements 412 are spaced apart on the second mounting surface 414. The plurality of first suction elements 411 are spaced apart in sequence along the rotation axis of the paper pickup seat 403, and the plurality of second suction elements 412 are spaced apart in sequence along the rotation axis of the paper pickup seat 403. The plurality of first suction elements 411 and the plurality of second suction elements 412 improve the stability of the cup holder suction.

[0071] Furthermore, the paper pick-up seat 403 has a first mounting surface 413 and a second mounting surface 414 that are opposite to each other, a plurality of first absorbers 411 are mounted on the first mounting surface 413, and a plurality of second absorbers 412 are mounted on the second mounting surface 414. When the paper pick-up seat 403 rotates, the first absorbers 411 and the second absorbers 412 can alternately absorb the cup holder in a direction perpendicular to the paper surface of the cup holder.

[0072] Optionally, the paper pick-up seat 403 includes a U-shaped frame 422 and a first pick-up paperboard 423 and a second pick-up paperboard 424, both mounted on the U-shaped frame 422. The first pick-up paperboard 423 and the second pick-up paperboard 424 are respectively mounted on two outer sides of the U-shaped frame 422 that face away from each other, with the first mounting surface 413 located on the first pick-up paperboard 423 and the second mounting surface 414 located on the second pick-up paperboard 424. When the first pick-up paperboard 423 and the second pick-up paperboard 424 are mounted on the U-shaped frame 422, an avoidance groove is formed. One end of the first absorbent 411 and one end of the second absorbent 412 are both located in the avoidance groove, thereby preventing interference between the first absorbent 411 and the second absorbent 412 and the U-shaped frame 422, thereby facilitating the installation of the first absorbent 411 and the second absorbent 412.

[0073] The U-shaped frame 422 forms a pipe connection slot. The inner wall of the pipe connection slot is provided with a first pipe connection slot, a second pipe connection slot, and a third pipe connection slot. This slot not only reduces the weight of the U-shaped frame 422 but also prevents interference between the pipes and other components, facilitating pipe routing. By connecting the pipes to a pump, negative pressure is generated in the first and second absorbers 411, 412, thereby attracting the cup holder.

[0074] Furthermore, a rotating slip ring 419 is mounted on the base 401. This is an electrical component responsible for connecting the rotating body and transmitting energy and signals. A fourth pipe joint is provided on the rotating slip ring 419. This connection connects the pipes and provides negative air pressure to the first and second suction chambers 411 and 412 on the paper pick-up base 403. The rotating slip ring 419 is connected to the vacuum generator via the fourth pipe joint. The first and second pipe joints are both connected to a fourth pipe joint via a third pipe joint. This allows the cup holder conveyor device to be routed using only four air pipes.

[0075] In one embodiment, the paper separation mechanism 4 further includes a positioning wheel 415 mounted on the base 401, a second driven wheel 416 rotatably mounted on the rotating base 402, and a second transmission belt 417 sleeved around the positioning wheel 415 and the second driven wheel 416. The positioning wheel 415 is fixedly mounted on the base 401 and is coaxially arranged with the first driven wheel 408. The axle of the first driven wheel 408 directly passes through the wheel hole in the positioning wheel 415 and is in transmission connection with the rotating base 402, driving the rotating base 402 to rotate. The positioning wheel 415 is stationary. The rotating base 402 has an axle hole, and the paper removal base 403 has a connecting shaft.

[0076] The fourth motor 406 is in transmission connection with the rotating base 402 via a wheel axle. The paper pickup base 403 is in transmission connection with the second driven pulley 416 via a connecting shaft extending through a shaft hole. A second tensioning pulley is mounted on the rotating base 402 to tension the second transmission belt 417. The rotating base 402 is in transmission connection with the fourth motor 406 to rotate. Since the paper pickup base 403 is mounted on the rotating base 402, it can rotate along with the rotating base 402 around its axis. In addition, since the connecting seat on the paper picking seat 403 passes through the axial hole on the rotating seat 402, the rotating seat 402 directly pushes the paper picking seat 403 to rotate around the axis of the rotating seat 402 when it rotates. At the same time, through the cooperation of the positioning wheel 415, the second driven wheel 416, and the second transmission belt 417, the paper picking seat 403 rotates around the rotation axis of the second driven wheel 416 to realize the self-rotation of the paper picking seat 403. That is, the present application can simultaneously drive the rotating seat 402 and the paper picking seat 403 to rotate around the rotation axis of the rotating seat 402 through the fourth motor 406 to realize the revolution of the paper picking seat 403, and can also drive the paper picking seat 403 to revolve around its own axis to realize the self-rotation of the paper picking seat 403.

[0077] Optionally, the paper tray is adsorbed or placed once every 120° rotation of the rotating base 402 and every 180° rotation of the paper pick-up base 403. The gear ratio of the positioning wheel 415 to the second driven wheel 416 is 3:2, and the transmission ratio of the positioning wheel 415 to the second driven wheel 416 is 2:3. This ensures that when the first suction assembly 404 or the second suction assembly 405 adsorbs the cup tray, the first suction assembly 404 or the second suction assembly 405 rotates 120° along with the wheel shaft and the rotating base 402, ensuring that the first suction assembly 404 or the second suction assembly 405 is perpendicular to the paper surface of the cup tray.

[0078] Optionally, the paper feed mechanism 5 includes a frame 501, a transmission wheel assembly rotatably mounted on the frame 501, a conveyor belt assembly 502 mounted on the transmission wheel assembly, a drive shaft 503 rotatably mounted on the frame 501, a one-way bearing assembly mounted on the drive shaft 503 and transmission-connected to the transmission wheel assembly, and a pusher 504 having a telescopic rod. The telescopic rod of the pusher 504 is transmission-connected to the drive shaft 503 to drive the one-way bearing assembly for unidirectional rotation. A paper feed channel is located above the conveyor belt assembly 502 and has a paper loading end 505 and a paper drop end 506. A cup holder is stacked on the paper feed channel from the paper loading end 505 along the extending direction of the paper feed channel and then moves along the paper feed channel to the paper drop end 506. The first suction assembly 404 and the second suction assembly 405 alternately approach and move away from the paper drop end 506 of the paper feed channel, and the paper separator 4 picks up the cup holder from the paper drop end 506. Specifically, the one-way bearing assembly includes at least one one-way bearing body 507, which is a bearing that can rotate freely in one direction but is locked in the other. A one-way bearing is also called an overrunning clutch. The conveyor belt assembly 502 includes several conveyor belts and conveyor wheels that drive the conveyor belts. The conveyor belts can be belts or chains. The one-way bearing assembly is connected to the conveyor wheels via a drive shaft 503, allowing the conveyor belts to move the cup holders. The pusher 504 is a pneumatic cylinder. Taking advantage of the one-way bearing assembly's ability to rotate in only one direction, the pusher 504's telescopic rod extends, which, driven by the drive shaft 503, pushes the one-way bearing assembly in one direction, causing the conveyor belt to move the cup holders along the conveyor belt toward the paper drop end 506. When the pusher 504's telescopic rod retracts, the drive shaft 503 and conveyor belt remain stationary. When the pusher 504's telescopic rod extends again, the conveyor belt continues to transport the cup holders, ultimately achieving intermittent delivery of the cup holders.

[0079] Furthermore, the conveyor belt assembly 502 has a straight section and an inclined section arranged in sequence. The straight section extends horizontally, while the inclined section extends downwardly and away from the straight section. The paper loading end 505 is located at one end of the straight section, and the other end of the straight section extends in a direction close to one end of the inclined section. The paper drop end 506 is located at the other end of the inclined section. Specifically, the conveyor belt assembly 502 includes a first conveyor belt 509 and a second conveyor belt 510. There are two first conveyor belts 509 arranged at intervals along the width of the cup holder conveying path, and there are two second conveyor belts 510 arranged at intervals along the width of the cup holder conveying path, with the two first conveyor belts 509 and the two second conveyor belts 510 corresponding one to one. The first conveyor belt 509 is arranged horizontally, with the straight section located on the first conveyor belt 509. The second conveyor belt 510 is arranged downwardly and inclined from top to bottom, with the inclined section located on the second conveyor belt 510. The one-way bearing assembly includes at least two one-way bearing bodies 507. The one-way bearing body 507 is mounted on the frame 501 via a bearing seat. The telescopic rod of the pusher 504 is in transmission connection with the one-way bearing body 507 or the bearing seat to drive the one-way bearing body 507 to rotate. At least one one-way bearing body 507 is in transmission connection with the conveyor roller of the first conveyor belt 509, and at least one one-way bearing body 507 is in transmission connection with the conveyor roller of the second conveyor belt 510. In this way, the pusher 504 cooperates with the one-way bearing body 507 to enable the first conveyor belt 509 and the second conveyor belt 510 to transport cup holders. The second conveyor belt 510 is tilted so that the paper surface of the cup holder is tilted downward, facilitating suction by the paper separator 4.

[0080] Optionally, the frame 501 includes an upper paper stop 512, a lower paper stop 515, and a mounting beam 513. The frame 501 is fixedly mounted via the mounting beam 513. The upper paper stop 512 and the lower paper stop 515 are spaced apart from each other from top to bottom. Both the upper paper stop 512 and the lower paper stop 515 are located at the paper drop end 506 to prevent the cup holder from falling out along the paper drop end 506 of the inclined second conveyor belt 510 due to gravity. When the paper separation mechanism 4 attracts the cup holder, the cup holder is deformed and is attracted and removed from the paper drop end 506 after it is separated from the second conveyor belt 510.

[0081] Furthermore, the paper feeding mechanism 5 includes a roller 514 rotatably mounted on the frame 501. The roller 514 is located at the lower end of the second conveyor belt 510, near the paper drop end 506. The roller 514 prevents the cup holder from falling on the 60° inclined second conveyor belt 510 and ensures smooth suction and removal of the cup holder.

[0082] In one embodiment, the paper feeding mechanism 5 further includes a paper pushing block 511. The paper pushing block 511 is mounted on a straight section of the conveyor belt assembly 502. The paper pushing block 511 is mounted on the first conveyor belt 509 and moves along with the first conveyor belt 509. The paper pushing block 511 can push the cup holders on the first conveyor belt 509 to the second conveyor belt 510, and the paper pushing block 511 can ensure that there are no gaps between the cup holders.

[0083] Furthermore, the projection of the transmission shaft 503 along its own rotation axis is hexagonal. The transmission shaft 503 is a hexagonal shaft, which is a type of transmission mechanism. It is characterized by a compact structure, light weight, high rigidity and high-speed performance, high load-bearing capacity, rigidity and bending resistance, long service life, etc., and is suitable for occasions where large torque and large loads are transmitted. The hexagonal shaft of the present application can better maintain its shape when subjected to torque and axial force, thereby improving the transmission stability and reliability of the paper feeding mechanism 5. The hexagonal shaft has six force-bearing surfaces, which can better disperse stress and thus withstand greater torque and pressure.

[0084] In one embodiment, the cup tray conveying device further includes a blowing nozzle 508. The blowing nozzle 508 is mounted on the frame 501 and located above the paper drop end 506. The blowing nozzle 508 blows a gap between adjacent cup trays to ensure that the paper separation mechanism 4 does not simultaneously absorb two cup trays when absorbing the cup trays.

[0085] In one embodiment, the cup holder assembly apparatus further includes a control mechanism 6. The cup holder conveying mechanism 1, the cup body conveying mechanism 2, the cup separating mechanism 3, the paper separating mechanism 4, and the paper feeding mechanism 5 are all electrically connected to the control mechanism 6. The control mechanism 6 includes a control box and a controller installed within the control box. The control mechanism 6 is used to control the cup holder conveying mechanism 1, the cup body conveying mechanism 2, the cup separating mechanism 3, the paper separating mechanism 4, and the paper feeding mechanism 5.

[0086] This embodiment further provides a cup holder assembly method, based on the cup holder assembly device described in any of the above embodiments, the cup holder assembly method includes the following steps:

[0087] S10: The cup holder is delivered to the cup holder conveying channel 101 of the cup holder conveying mechanism 1 and moves along the cup holder conveying channel 101. The cup body 7 is delivered to the cup body conveying channel 201 of the cup body conveying mechanism 2 and moves along the cup body conveying channel 201, passing through the power section 205 and the guide section 206 in sequence. The cup sorting turntable 305 then drives the sorting plate 306 to rotate, thereby sorting the cup bodies 7.

[0088] S20: The cup dividing turntable 302 is driven to rotate, and the multiple cup bodies 7 on the guide section 206 of the cup conveying channel 201 are first pushed into the grouping space 304 by the dividing plate 303 to form product groups. Then, the dividing plate 303 pushes the divided product groups from the lower cup end 204 of the cup conveying channel 201 to the cup holder of the cup holder conveying channel 101.

[0089] S30 : conveying the cup holder and the product group on the cup holder along the cup holder conveying channel 101 of the cup holder conveying mechanism 1 .
