Description

Technical Field

[0001] This utility model belongs to the field of cup making machine technology, and specifically relates to a processing mechanism with automatic adjustment function 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 in efficiency. A significant factor limiting efficiency is the machining mechanism, most commonly the upper and lower mold type. The distance between the upper and lower molds in existing upper and lower mold type structures is inconvenient to adjust. This means that when processing different types of products, a lot of time and effort is required to disassemble the entire device for adjustment, which is detrimental to improving the production efficiency of disposable cups.

[0004] 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

[0005] In order to solve the above problems, the purpose of this utility model is to provide a processing mechanism with an automatic adjustment function, which can automatically adjust the distance and improve production efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A processing mechanism with automatic adjustment function is characterized by including a flipping mold opening and closing mechanism, which has a lifting platform, an upper mold and a lower mold. 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. The lifting platform can also flip the lower mold to discharge the processed products.

[0008] The upper mold is connected to an adjustable motor and an adjustable rod. The adjustable rod is connected to the upper mold, and the output shaft of the adjustable motor is connected to the adjustable rod, so that the upper mold can be moved closer to or away from the lower mold through the adjustable rod.

[0009] In this invention, by setting an adjustable distance motor and an adjustable distance rod, the distance between the upper and lower molds can be easily and automatically adjusted. When processing different products, there is no need for complicated disassembly operations to adjust the distance between the upper and lower molds, thereby improving production efficiency.

[0010] Furthermore, there are two adjusting motors and four adjusting rods. The two adjusting motors are respectively located on the left and right sides of the upper mold and drive two adjusting rods respectively. Two adjusting rods are located at both ends of one side of the top of the upper mold, and the other two adjusting rods are located at both ends of the other side of the top of the upper mold. Each adjusting rod is threadedly connected to the upper mold, so that the upper mold moves closer to or away from the lower mold by rotation. Since the upper mold is relatively heavy, using two adjusting motors and four adjusting rods, symmetrically distributed on both sides of the top of the upper mold, ensures stability during the distance adjustment process between the upper and lower molds and improves the overall service life of the structure. Preferably, the two adjusting rods on the top sides of the upper mold are engaged by a transmission wheel. In this way, the output shaft of the adjusting motor only needs to be connected to one adjusting rod to drive the other adjusting rod to rotate, resulting in a simple overall structure.

[0011] Furthermore, the processing mechanism also includes a driving mechanism, which has a flipping driving component and an opening and closing driving component. The flipping driving component is connected to the lifting platform to drive the lifting platform to flip, and the opening and closing driving 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.

[0012] The opening and closing drive assembly includes a motor, a drive shaft, an eccentric wheel, and an actuator arm. The motor is connected to the drive shaft to drive its rotation, and the drive shaft is connected to the eccentric wheel to drive its rotation. One end of the actuator arm has a mounting hole that matches the outer contour of the eccentric wheel, and the eccentric wheel is installed in the mounting hole to drive the actuator arm's movement. 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. By setting the actuator arm with a mounting hole at one end that matches the outer contour of the eccentric wheel, and installing the eccentric wheel in the mounting hole to drive the actuator arm's movement, 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 force of faster mold opening and closing, thereby effectively improving production efficiency and overcoming the bottlenecks of the prior art.

[0013] 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.

[0014] Furthermore, the processing mechanism with automatic adjustment function 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 and upper molds in opening and closing, as well as flipping the lower mold after opening. One end of each adjusting rod is connected to the mounting frame via a bearing. The mounting frame supports the adjusting rod and provides rotational freedom.

[0015] 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.

[0016] 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.

[0017] 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,

[0018] 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.

[0019] 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.

[0020] 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 movement of a heavier lifting platform and lower mold, and allowing it to withstand the impact of faster mold opening and closing, thereby effectively improving production efficiency and overcoming the bottlenecks of existing technologies.

[0021] The beneficial effect of this utility model is that by setting an adjustable distance motor and an adjustable distance rod, the distance between the upper mold and the lower mold can be easily and automatically adjusted. When processing different products, there is no need for complicated disassembly operations to adjust the distance between the upper mold and the lower mold, thereby improving production efficiency.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] See Figure 1-3 A processing mechanism with automatic adjustment function, comprising:

[0034] The flipping mold opening and closing mechanism 1 has an upper mold 11, a lower mold 12 and a lifting platform 13. The lower mold 11 is detachably connected to the lifting platform 13 so that the lower mold 12 can move up and down relative to the upper mold 11 through the lifting platform 13 to open and close the mold to process products; and the lifting platform 13 can drive the lower mold 12 to flip so as to realize the discharge of processed products.

[0035] An adjustable distance motor 100 and an adjustable distance rod 200 are connected to the upper mold 11. The adjustable distance rod 200 is connected to the upper mold 11, and the output shaft of the adjustable distance motor 100 is connected to the adjustable distance rod 200 so that the upper mold 11 can be moved closer to or further away from the lower mold 12 through the adjustable distance rod 200.

[0036] In this utility model, by setting the adjustable distance motor 100 and the adjustable distance rod 200, the distance between the upper mold 11 and the lower mold 12 can be easily and automatically adjusted. When processing different products, there is no need for complicated disassembly operations to adjust the distance between the upper mold 11 and the lower mold 12, thereby improving production efficiency.

[0037] In this embodiment, there are two adjusting motors 100 and four adjusting rods 200. The two adjusting motors 100 are respectively located on the left and right sides of the upper mold 11 and drive and connect to the two adjusting rods 200 respectively. Two adjusting rods 200 are located at both ends of one side of the top of the upper mold 11, and the other two adjusting rods 200 are located at both ends of the other side of the top of the upper mold. Each adjusting rod 200 is threadedly connected to the upper mold 11 so that the upper mold 11 can be rotated to move closer to or away from the lower mold 12. Since the upper mold 11 is relatively heavy, the use of two adjusting motors 100 and four adjusting rods 200, symmetrically distributed on both sides of the top of the upper mold 11, can ensure the stability of the distance adjustment process between the upper mold 11 and the lower mold 12 and improve the overall service life of the structure. Preferably, the two adjusting rods 200 on both sides of the top of the upper mold 11 are engaged by a transmission wheel 300. In this way, the output shaft of the adjusting motor 100 only needs to be connected to one of the adjusting rods 200 to drive the other adjusting rod 200 to rotate, resulting in a simple overall structure.

[0038] In this embodiment, the processing mechanism further includes a drive mechanism 2, which has a flipping drive component 21 and an opening and closing drive component 22. The flipping drive component 21 is connected to the lifting platform 13 to drive the lifting platform 13 to flip, and the opening and closing drive component 22 is connected to the lifting platform 13 to drive the lifting platform 13 to drive the lower mold 12 to move up and down relative to the upper mold 11.

The eccentric wheel 223 is installed in the mounting hole 2241 to drive the actuator arm 224 to move. 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.

[0041] 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...

A slide rail 31 is provided on the mounting frame 3, and a slider 32 is slidably connected to the slide rail 31. The lifting platform 13 is rotatably connected to the slider 32 and can rise and fall with the slider 32 on the slide rail 31. The above structure can ensure the realization of the lifting function and the flipping function of the lower mold 12, thereby assisting the lower mold 12 and the upper mold 11 in opening and closing the mold, as well as realizing the flipping of the lower mold 12 after opening the mold.

One end of the first linkage group 225 is hinged to the mounting bracket 3, and the other end of the first linkage group 225 is hinged to one end of the first opening and closing rod 226. 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.

[0044] 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.

Both ends of the stabilizing linkage 229 are hinged to the mounting grooves 4 in the first opening and closing rod 226 and the second opening and closing rod 228, respectively. This arrangement allows for efficient use of space. In this utility model, the second opening and closing rod 228 can assist in the opening, closing and flipping of the lifting platform 13. When it is in contact with the lifting platform 13, it can assist in the application of force. When it is detached, it can prevent interference with the first opening and closing rod 226 and affect the degree of freedom of movement of the first opening and closing rod 226 and the lifting platform 13.

[0045] In this embodiment, the opening and closing drive assembly 22 further includes a first rotating shaft 5, a second rotating shaft 6, and a third rotating shaft 7.

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.
