Description

Technical Field

[0001] This utility model belongs to the field of cup making machine technology, and specifically relates to a flip-opening and closing mold structure and a cup making machine. Background Technology

[0002] Disposable cups are widely used in daily life. In order to improve the production efficiency of disposable cups, automated equipment for producing disposable cups has appeared on the market, thus the production efficiency of disposable cups is constantly improving.

[0003] However, after automated production equipment has developed to a certain stage, its production efficiency has encountered a bottleneck, thus limiting further improvements. A crucial factor limiting efficiency is the tilting and opening / closing mold structure. This structure is the core of the automatic cup-making machine, comprising the mold that extrudes the film-shaped raw material into finished cups, and the drive mechanism that rotates and opens / closes the mold. Existing drive mechanisms, using only cams, struts, and push rods to rotate and open / close the mold, suffer from point contact with a small contact area, making them unable to withstand significant forces and thus limiting production speed. For example, when the drive mechanism is needed to move heavier molds or achieve faster tilting and opening / closing speeds, the contact points between the cams and struts / push rods bear greater forces, making them prone to damage.

[0004] For example, a fully automatic flipping molded cup machine (CN119748829B) disclosed in the prior art uses a "point" contact method between the cam and the support rod / push rod. See its instruction manual for details.

[0005] The flipping assembly includes a first push rod 401, a second push rod 402, a linkage rod 403, a flipping pull rod 404, and a first cam 405. The first push rod 401 and the second push rod 402 are both rotatably mounted on the base 100. The linkage rod 403 is located between the first push rod 401 and the second push rod 402, and its two ends are respectively hinged to the first push rod 401 and the second push rod 402. The flipping pull rod 404 is hinged to the second push rod 402. The second mold 220 is provided with a flipping shaft 224. The end of the flipping pull rod 404 away from the second push rod 402 is hinged to the flipping shaft 224. The first cam 405 is rotatably mounted between the first push rod 401 and the second push rod 402 through a power assembly 600. When the first cam 405 rotates, it can push the first push rod 401 and the second push rod 402 to rotate.

[0006] The movable assembly may include a first support rod 501, a second support rod 502, a connecting rod 503, an opening / closing lever 504, a second cam 505, and a linkage assembly. Both the first support rod 501 and the second support rod 502 are rotatably mounted on the base 100. The connecting rod 503 is located between the first support rod 501 and the second support rod 502, with both ends rotatably connected to the first support rod 501 and the second support rod 502, respectively. A main shaft 102 is rotatably mounted on the base 100 via a bearing seat. A mounting block is fixed on the main shaft 102. Both ends of the opening / closing lever 504 are hinged to the second support rod 502 and the mounting block, respectively. The linkage assembly is located between the main shaft 102 and the tilting shaft 224, and is used to push the second mold 220 to move, thereby enabling the first mold 210 and the second mold 220 to close or disengage. The second cam 505 is rotatably mounted between the first support rod 501 and the second support rod 502 via the power assembly 600. When the second cam 505 rotates, it can push the first support rod 501 and the second support rod 502 to rotate.

[0007] Given the above situation, there is an urgent need for a structure that can break through the aforementioned bottlenecks and further improve the production efficiency of cup-making machines. Utility Model Content

[0008] In order to solve the above problems, the purpose of this utility model is to provide a flip-opening and closing mold structure, which has high structural strength, good transmission effect, and can improve production efficiency.

[0009] Another objective is to provide a cup-making machine that adopts the aforementioned flip-opening and closing mold structure, which has high strength, good transmission effect, and can improve production efficiency.

[0010] To achieve the above objectives, the technical solution of this utility model is as follows.

[0011] A flip-opening and closing mold structure, comprising a lifting platform, an upper mold, and a lower mold, wherein the lower mold is detachably connected to the lifting platform so that the lower mold can move up and down relative to the upper mold to open and close the mold to process products; and the lifting platform can also flip the lower mold to discharge the processed products.

[0012] The driving mechanism has a flipping drive component and an opening and closing drive component. The flipping drive component is connected to the lifting platform to drive the lifting platform to flip. The opening and closing drive component is connected to the lifting platform to drive the lifting platform to drive the lower mold to move up and down relative to the upper mold.

[0013] The feature is that the opening and closing drive assembly includes a motor, a transmission shaft, an eccentric wheel, and an actuator arm. The motor is connected to the transmission shaft to drive the transmission shaft to rotate. The transmission shaft is connected to the eccentric wheel to drive the eccentric wheel to rotate. One end of the actuator arm is provided with a mounting hole that matches the outer contour of the eccentric wheel. The eccentric wheel is installed in the mounting hole to drive the actuator arm to move. The other end of the actuator arm is connected to the lifting platform to drive the lifting platform and the lower mold to move up and down relative to the upper mold.

[0014] This invention features an actuator arm with a mounting hole at one end that matches the outer contour of an eccentric wheel. The eccentric wheel is then installed in the mounting hole to drive the actuator arm. This unique mating structure allows for surface contact between the eccentric wheel and the actuator arm. Compared to the point contact structure in the prior art, this significantly improves the strength of the structure, enabling it to drive heavier lifting platforms and lower molds, and withstand the impact of faster mold opening and closing. This effectively improves production efficiency and overcomes the bottlenecks of the prior art.

[0015] Furthermore, a bearing is provided at one end of the actuator arm, and the mounting hole is located within the bearing. The bearing allows relative rotation between the eccentric wheel and the actuator arm, thereby reducing the friction between the eccentric wheel and the actuator arm during operation and extending the service life of both.

[0016] Furthermore, the flip-opening and closing mold structure also includes a mounting frame. The lifting platform, upper mold, lower mold, and drive mechanism are all mounted on the mounting frame. The mounting frame is equipped with a slide rail, and a slider is slidably connected to the slide rail. The lifting platform is rotatably connected to the slider and can rise and fall with the slider on the slide rail. The above structure ensures that the lower mold can follow the lifting platform to achieve lifting and flipping functions, thereby assisting the lower mold and upper mold in opening and closing, as well as achieving the flipping of the lower mold after opening.

[0017] Furthermore, the opening and closing drive assembly also includes a first linkage group and a first opening and closing rod. One end of the first linkage group is hinged to the mounting bracket, and the other end of the first linkage group is hinged to one end of the first opening and closing rod. The other end of the first opening and closing rod is hinged to the lifting platform to drive the lifting platform and the lower mold to move up and down. In fact, the first opening and closing rod can also assist in realizing the flipping movement of the lower mold.

[0018] Furthermore, the opening and closing drive assembly also includes a second linkage group, a second opening and closing rod, and a stabilizing linkage. One end of the second linkage group is hinged to the mounting frame, and the other end of the second linkage group is hinged to one end of the second opening and closing rod. The other end of the second opening and closing rod abuts against or disengages from the lifting platform. Both ends of the stabilizing linkage are hinged to the first opening and closing rod and the second opening and closing rod, respectively. Preferably, both the first and second opening and closing rods are provided with mounting grooves, and both ends of the stabilizing linkage are hinged to the mounting grooves in the first and second opening and closing rods, respectively. This arrangement can make reasonable use of space. In this utility model, the second opening and closing rod can assist in applying force during the opening, closing, and flipping of the lifting platform. When abutting, it can assist in applying force; when disengaged, it can prevent interference with the first opening and closing rod, thus avoiding affecting the degree of freedom of movement of the first opening and closing rod and the lower mold.

[0019] Furthermore, the opening and closing drive assembly also includes a first rotating shaft, a second rotating shaft, and a third rotating shaft. The first linkage group includes two parallel first linkages, one end of each of the two first linkages being movably sleeved on the first rotating shaft. The first rotating shaft is rotatably connected to the mounting bracket. The other end of the actuator arm is movably sleeved on the second rotating shaft, which is rotatably connected to the first linkage. The other ends of both first linkages are movably sleeved on the third rotating shaft, and one end of the first opening / closing rod is movably sleeved on the third rotating shaft. The second rotating shaft is located between the first and third rotating shafts; and / or,

[0020] The opening and closing drive assembly also includes a fourth and a fifth rotating shaft. The second linkage group includes two parallel second linkages, one end of which is movably sleeved on the fourth rotating shaft, which is rotatably connected to the mounting bracket. The other end of each of the two second linkages is movably sleeved on the fifth rotating shaft, and one end of the second opening / closing rod is movably sleeved on the fifth rotating shaft. The first and second linkages are both parallel to each other, creating an installation space between them for the actuator arm to pass through, or for the first and second opening / closing rods to extend into and movably sleeve on the rotating shaft. This structural design not only reduces the size but also enhances the stability of the structure through structural cooperation.

[0021] Furthermore, the flipping drive assembly includes a first cam, a first push rod, a second cam, a second push rod, a first flipping link, and a second flipping link. Both the first and second cams are sleeved on the transmission shaft to rotate with it. One end of the first push rod and one end of the second push rod are hinged to the mounting bracket. Both ends of the first flipping link are hinged to the other ends of the first push rod and the second push rod, respectively, to achieve linkage between the first and second push rods. One end of the second flipping link is hinged to the other end of the second push rod, and the other end of the second flipping link is hinged to the lifting platform to drive the lifting platform and the lower mold to flip. The first push rod is provided with a first trigger part that cooperates with the first cam to drive the first push rod to move backward, and the second push rod is provided with a second trigger part that cooperates with the second cam to drive the second push rod to move forward. The first and second triggering parts can be a single triggering protrusion or a roller rotatably mounted on the first and second push rods. In this invention, the first and second cams and the eccentric wheel are all sleeved on the transmission shaft, achieving a common track configuration. They can be driven by a single power source, eliminating the need for complex program control. Simply by setting the angles and dimensions of the three components appropriately, normal operation and non-interference can be achieved. Specifically, to achieve downward tilting of the lower mold, the first cam rotates to abut against the first triggering part, which in turn drives the first push rod backward. The first push rod, through the first tilting linkage, drives the second push rod backward synchronously. The second push rod, through the second tilting linkage, pulls the lifting platform, thus tilting the lifting platform and the lower mold downward. To achieve upward tilting of the lower mold, the second cam rotates to abut against the second triggering part, which in turn drives the second push rod forward. The second push rod, through the second tilting linkage, pushes the lifting platform, thus tilting the lifting platform and the lower mold upward.

[0022] Furthermore, the opening and closing drive assembly consists of two sets, corresponding to the bottom two sides of the lifting platform respectively. Having two sets of opening and closing drive assemblies further enhances the structural strength, enabling the lifting platform and lower mold to move more heavily, and also allowing it to withstand the impact of faster mold opening and closing, thereby effectively improving production efficiency and overcoming the bottlenecks of existing technologies.

[0023] This utility model also provides a cup-making machine, which adopts the above-mentioned flip-opening and closing mold structure, and the cup-making machine includes:

[0024] Feeding mechanism: feeding raw materials;

[0025] Heating mechanism: used to heat and soften raw materials;

[0026] Flip-opening mold structure: used to process softened raw materials into finished cups;

[0027] Rotary cup receiving mechanism: used to remove the finished cup from the flip-opening mold structure;

[0028] Storage mechanism: Used to store finished cups taken out by the rotating cup receiving mechanism;

[0029] Feeding mechanism: Used to feed finished cups out of the storage mechanism;

[0030] The feeding mechanism, heating mechanism, flipping mold opening and closing structure, rotating cup receiving mechanism, material storage mechanism and unloading mechanism are connected in sequence to form a production path.

[0031] The beneficial effects of this utility model are as follows: By setting an actuator arm with a mounting hole at one end that matches the outer contour of the eccentric wheel, the eccentric wheel is installed in the mounting hole to drive the actuator arm. This unique mating structure allows for surface contact between the eccentric wheel and the actuator arm. Compared to the point contact structure in the prior art, this significantly improves the strength of the structure, enabling it to drive heavier lifting platforms and lower molds, and withstand the impact of faster mold opening and closing, thereby effectively improving production efficiency and breaking through the bottlenecks of the prior art. The cup-making machine of this utility model, with its flip-opening and closing mold structure, can greatly improve production efficiency. Attached Figure Description

This unique mating structure can achieve surface contact between the eccentric wheel 223 and the actuator arm 224. Compared with the point contact structure in the prior art, this structure can greatly improve its strength, thereby driving the heavier lifting platform 13 and lower mold 12 to move, and can also withstand the impact force of faster mold opening and closing, thus effectively improving production efficiency and breaking through the bottleneck of the prior art.

[0058] In this embodiment, a bearing 2242 is provided inside one end of the actuator arm 224, and a mounting hole 2241 is provided inside the bearing 2242. The bearing 2242 allows relative rotation between the eccentric wheel 223 and the actuator arm 224, thereby reducing the friction between the eccentric wheel 223 and the actuator arm 224 during movement and extending the service life of the eccentric wheel 223 and the actuator arm 224. Specifically, the through hole on the inner ring of the bearing 2242 is configured as the mounting hole 2241, and the eccentric wheel 223 is fixed in the mounting hole 2241 on the inner ring of the bearing 2242. A fixing hole adapted to the outer ring of the bearing is provided inside one end of the actuator arm 224, and the outer ring of the bearing 2242 is...

The other end of the first opening and closing rod 226 is hinged to the lifting platform 13 to drive the lower mold 12 to move up and down. In fact, the first opening and closing rod 226 can also assist in realizing the flipping movement of the lifting platform 13 and the lower mold 12.

[0061] In this embodiment, the opening and closing drive assembly 22 further includes a second linkage group 227, a second opening and closing rod 228, and a stabilizing linkage 229. One end of the second linkage group 227 is hinged to the mounting frame 3, and the other end of the second linkage group 227 is hinged to one end of the second opening and closing rod 228. The other end of the second opening and closing rod 228 abuts against or disengages from the lifting platform 13.

The first linkage 2251 and the second linkage 2271 are both parallel to each other, forming an installation space between them. This space allows the actuator arm 224 to pass through, or allows the first opening / closing rod 226 and the second opening / closing rod 228 to extend into and movably sleeve on the rotating shaft. This structural design not only reduces the size but also enhances the stability of the structure through structural cooperation.

[0064] In this embodiment, the flipping drive assembly 21 includes a first cam 211, a first push rod 212, a second cam 213, a second push rod 214, a first flipping connecting rod 215, and a second flipping connecting rod 216. The first cam 211 and the second cam 213 are both sleeved on the drive shaft 222 to rotate with it. One end of the first push rod 212 and one end of the second push rod 214 are both hinged to the mounting bracket 3. The two ends of the first flipping connecting rod 215 are respectively connected to the other ends of the first push rod 212 and the second push rod 214. The first push rod 212 and the second push rod 214 are hinged together to achieve linkage. One end of the second flipping link 215 is hinged to the other end of the second push rod 214, and the other end of the second flipping link 216 is hinged to the lifting platform 13 to drive the lower mold 12 to flip. The first push rod 212 is provided with a first trigger part 2121 that cooperates with the first cam 211 to drive the first push rod 212 to move backward. The second push rod 214 is provided with a second trigger part 2141 that cooperates with the second cam 213 to drive the second push rod 214 to move forward. The first trigger part 2121 and the second trigger part 2141 can be a trigger protrusion or a roller rotatably mounted on the first push rod 212 and the second push rod 214. In this utility model, the first cam 211, the second cam 213, and the eccentric wheel 223 are all sleeved on the transmission shaft 222. The three are set together on the same track and can be driven by a single power source. There is no need to set up a complex program control. As long as the angles and dimensions of the three are reasonably set, normal operation can be achieved without interference between them. In specific operation, to achieve downward flipping of the lower mold 12, the first cam 211 rotates to abut against the first trigger part 2121. The first trigger part 2121 drives the first push rod 212 to move backward. The first push rod 212 drives the second push rod 214 to move backward synchronously through the first flipping connecting rod 215. The second push rod 214 then pulls the lifting platform 13 through the second flipping connecting rod 215, thereby achieving downward flipping of the lifting platform 13 and the lower mold 12. To achieve upward flipping of the lower mold 12, the second cam 213 rotates to abut against the second trigger part 2141. The second trigger part 2141 drives the second push rod 214 to move forward. The second push rod 214 then pushes the lifting platform 13 through the second flipping connecting rod 215, thereby achieving upward flipping of the lifting platform 13 and the lower mold 12.

[0065] In this embodiment, there are two sets of opening and closing drive components 22, corresponding to the bottom sides of the lifting platform 13 respectively. Having two sets of opening and closing drive components 22 can further improve the strength of the structure, thereby driving the heavier lifting platform 13 and lower mold 12 to move, and can also withstand the impact force of faster mold opening and closing, thus effectively improving production efficiency and breaking through the bottleneck of the prior art.

[0066] In this embodiment, the flip-opening mold structure also includes a protective plate 10, which covers the mounting hole 2241, and the protective plate 10 and the mounting hole 2241 together form a receiving cavity, in which the eccentric wheel 223 is located. The protective plate 10 can enhance the structural strength, protect the eccentric wheel 223, and limit the movement of the eccentric wheel 223 in the axial direction of the transmission shaft 222.

[0067] This utility model also provides a cup-making machine, which adopts the above-mentioned flip-opening and closing mold structure, and the cup-making machine includes:

[0068] Feeding mechanism 100: Feeding raw materials;

[0069] Heating mechanism 200: used to heat and soften raw materials;

[0070] Flip-opening mold structure 300: used to process softened raw materials into finished cups;

[0071] Rotary cup receiving mechanism 400: used to remove the finished cup from the flip-opening mold structure;

[0072] Storage mechanism 500: Used to store finished cups taken out by the rotating cup receiving mechanism;

[0073] Feeding mechanism 600: Used to feed finished cups out of the storage mechanism;

[0074] The feeding mechanism 100, heating mechanism 200, flipping mold opening and closing structure 300, rotating cup receiving mechanism 400, material storage mechanism 500 and unloading mechanism 600 are connected in sequence to form a production path.

[0075] In this embodiment, the cup-making machine also includes a frame 700, a heating mechanism 200, a flipping mold opening and closing structure 300, a rotating cup receiving mechanism 400, a material storage mechanism 500, and a material feeding mechanism 600, all of which are mounted on the frame 700.

[0076] In this embodiment, the feeding mechanism 100 includes a material rack 101 for placing raw materials and a feeding port 102, with the feeding port 102 located at the front end of the frame 700.

[0077] In this embodiment, the heating mechanism 200 includes two heating plates 201, which are arranged in parallel and their heating ends are arranged opposite each other to form a heating channel 202. The inlet of the heating channel is connected to the feed port 102, and the outlet of the heating channel corresponds to the flip-open mold structure 300, which is used to send the heated raw material between the upper mold 11 and the lower mold 12.

[0078] In this embodiment, the rotating cup receiving mechanism 400 includes a mounting plate 401, a receiving cylinder 402 for finished cups, and a rotary drive motor 403. The receiving cylinders 402 are evenly distributed on the front and rear sides of the mounting plate 401. The rotary drive motor 403 is driven to the mounting plate 401 to rotate the mounting plate 401, thereby rotating the receiving cylinders 402. A cup receiving slide rail 701 is provided on the frame 700. The mounting plate 401 and the rotary drive motor 403 are both slidably connected to the cup receiving slide rail 701 through the cup receiving slider 702 to realize the back-and-forth movement of the receiving cylinder 402, thereby enabling the receiving cylinder 402 to extend into the flipped lower mold 12 to remove the finished cup. The slidable connection can be achieved by using a cylinder fixed on the frame 700 to drive the cup receiving slider 702 to slide on the cup receiving slide rail 701; or by using a motor to drive the cup receiving slider 702 to slide. In actual operation, the receiving cylinder 402 moves forward and extends into the finished product cup. The finished product cup is taken out through the interference fit between the receiving cylinder 402 and the finished product cup. Then, the rotation drive motor 403 drives the mounting plate 401 to rotate. The mounting plate 401 then slides backward on the cup receiving slide rail 701, realizing the rotation and backward sliding of the receiving cylinder 402. Finally, the finished product cup is sent into the storage mechanism 500.

[0079] In this embodiment, the material storage mechanism 500 includes a material frame 501 with a cup-filling slot 502. The cup-filling slot 502 corresponds one-to-one with the receiving cylinder 402. The cup-filling slot 502 extends through the material frame 501 from front to back, forming a cup-receiving opening at the front and a cup-discharging opening at the rear. The cup-filling slot 502 and the finished cup can also be fitted with an interference fit, so that after the receiving cylinder 402 extends into the cup-filling slot 502 from the cup-receiving opening, the finished cup can be just right inside the cup-filling slot 502. Through continuous production and processing, the number of finished cups in the cup-filling slot 502 can increase.

[0080] In this embodiment, the storage mechanism 500 can be configured as two separate but connected sets. The two sets of storage mechanisms 500 can move independently without interfering with each other. This allows the first set of storage mechanisms 500 to continue loading finished product cups while the second set of storage mechanisms 500 is discharging material, without affecting each other. Furthermore, the second set of storage mechanisms 500 can be configured to be lifted and connected to the lifting rail 703 of the frame 700, thus adapting to various applicable scenarios when the second set of storage mechanisms 500 is discharging material.

[0081] In this embodiment, the feeding mechanism 600 includes a conveyor belt 601 and a feeding lever 602. The conveyor belt 601 corresponds to the cup outlet. The feeding lever 602 is movable and connected to the frame 700. The feeding lever 602 can rotate to avoid or hold the finished cup, so as to push the finished cup in the cup slot 502 onto the conveyor belt 601, and finally allow the finished cup to be discharged.

[0082] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
