Description

Technical Field

[0001] This utility model relates to the field of paper cup machines, and in particular to a servo synchronous and coordinated turntable positioning mechanism. Background Technology

[0002] In the forming equipment of paper cup or paper bowl machines, there is a mold and a forming mechanism. Generally, there are male mold turntables and female mold turntables, both equipped with molds. The forming mechanism consists of two parts: the cup bottom and the cup rim, which complete the paper cup forming. During the forming of the cup bottom and rim, the mechanism and mold use a layered demolding structure. Below the mold, there are corresponding actuators. Each time the male and female molds rotate through a station, the corresponding actuator at that station will move the paper cup. Therefore, the repeatability of each mechanism and mold is crucial for processing paper cups or bowls. In existing technology, during installation, the positioning of the male and female molds is linked to their respective servo motors. The servo positioning is very difficult to adjust, and the adjustment process is cumbersome and time-consuming. Therefore, a turntable with good repeatability is needed. Summary of the Invention

[0003] This invention addresses the drawback of difficulty in adjusting the positioning of the servo and the turntable in existing technologies by providing a servo-synchronized and coordinated turntable positioning mechanism.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:

[0005] The servo-synchronous rotary positioning mechanism includes a first servo motor and a rotary table. A mold for processing paper cups or paper bowls is mounted on the rotary table. The mechanism also includes a top plate, which is located above or below the rotary table. The housing of the first servo motor is fixedly connected to the top plate, and the output end of the first servo motor is connected to the rotary table. The top plate has a top plate positioning hole, and the rotary table has a rotary table positioning hole. A longitudinal positioning shaft is also provided. The longitudinal positioning shaft passes through the top plate positioning hole and is inserted into the rotary table positioning hole. There are two states in which the longitudinal positioning shaft is inserted into the rotary table positioning hole: one is that the end of the longitudinal positioning shaft is located in the rotary table positioning hole, and the other is that the end of the longitudinal positioning shaft extends outward after passing through the rotary table positioning hole. Both methods can achieve the positioning function.

[0006] Preferably, the turntable is a common mold turntable with stations evenly distributed circumferentially. Each station includes several processing stations and at least one idle station. Positioning holes are located in the idle stations, where molds for processing paper cups or bowls are installed. Positioning is achieved via a longitudinal positioning shaft in the idle station. This idle station does not participate in the processing of paper cups but shares the same dimensions as the processing stations on the same turntable. The idle station is specifically reserved for positioning and will not interfere with the installation or operation of stations already equipped with molds on the turntable. If every position has a mold, the mold will obstruct the positioning of the longitudinal positioning shaft at the station with the mold installed, causing inconvenience.

[0007] Preferably, the longitudinal positioning shaft includes a limiting part, the diameter of which is larger than the diameter of the positioning hole in the top plate. It can be suspended and positioned by its own gravity.

[0008] Preferably, the longitudinal positioning shaft passes through the positioning hole in the top plate from bottom to top and is then inserted into the positioning hole in the turntable, with the limiting part of the longitudinal positioning shaft located above the top plate.

[0009] Preferably, a platform is provided below the mold turntable, and an execution device is provided on the platform. Each execution device corresponds to the mold position on the processing station turntable. The execution device includes a lifting mechanism, which is connected to a second servo motor.

[0010] Preferably, the actuator includes a heating device, a cup bottom forming device, a bottom rolling device, a knurling device, and a cup loading robot.

[0011] Preferably, the turntable is a master mold turntable, the mold of the master mold turntable has an upward-facing cavity, the master mold turntable is provided with a cup ejection station, and the turntable positioning hole is provided on the cup ejection station.

[0012] Preferably, a flange for passing through the longitudinal positioning shaft is installed at the cup dispensing station.

[0013] This utility model, by adopting the above technical solution, has significant technical effects:

[0014] Positioning holes are provided at the workstations. These holes are either intentionally placed idle workstations or existing processing workstations, without affecting the normal assembly and processing of the molds. After the longitudinal positioning axis passes through the top plate and the turntable, the position of the servo motor can be determined, aligning the intermittent stop point of the first servo motor with the processing workstation. When the first servo motor, the turntable, and other power sources coordinate in position and synchronize in processing intervals, the synchronicity of the paper cup machine's operation is improved, as are the repeatability of the positioning of each mechanism and the mold.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] Servo-synchronous and coordinated turntable positioning mechanism, such as Figure 1-3 As shown, it includes a first servo motor 1 and a turntable 2. A mold 3 for processing paper cups or paper bowls is installed on the turntable 2. It also includes a top plate 4, which is located above or below the turntable 2. The housing of the first servo motor 1 is fixedly connected to the top plate 4. The output end of the first servo motor 1 is connected to the turntable 2. The top plate 4 has a top plate positioning hole 41, and the turntable 2 has a turntable positioning hole 21. It also has a longitudinal positioning shaft 5, which passes through the top plate positioning hole 41 and is inserted into the turntable positioning hole 21.

[0022] Turntable 2 is a public mold turntable. Turntable 2 has stations evenly arranged around its circumference. The stations include several processing stations and at least one idle station. The turntable positioning hole 21 is set on the idle hole. The mold 3 for processing paper cups or paper bowls is installed on the processing station.

[0023] The longitudinal positioning shaft 5 includes a limiting part 51, the diameter of which is larger than the diameter of the positioning hole 41 in the top plate.

[0024] The longitudinal positioning shaft 5 passes through the top plate positioning hole 41 from bottom to top and is then inserted into the turntable positioning hole 21. The limiting part 51 of the longitudinal positioning shaft 5 is located above the top plate 4.

[0025] A platform 6 is set below the mold turntable, and an execution device is set on the platform 6. Each execution device corresponds to the position of the mold 3 on the processing station turntable 2. The execution device includes a lifting mechanism, which is connected to a second servo motor.

[0026] The actuator includes a heating device 71, a cup bottom forming device 72, a bottom rolling device 73, a knurling device 74, and a cup loading robot 75.

[0027] Turntable 2 is a master mold turntable. The mold 3 of the master mold turntable has an upward-facing cavity. The master mold turntable 2 is provided with a cup ejection station, and the turntable positioning hole 21 is provided on the cup ejection station.

[0028] A flange for passing through the longitudinal positioning shaft 5 is installed at the cup dispensing station.

[0029] Turntable 2, taking the male mold as an example in the figure (the female mold is the same), has a turntable positioning hole 21 at the position of the first servo motor 1, and there is an empty station. The empty station does not need to install the mold 3. The top plate 4 is provided with a top plate positioning hole 41. The upper and lower turntable positioning holes 21 and the top plate positioning hole 41 are aligned. When designing turntable 2, a positioning position is determined because the center position is fixed, that is, it is connected to the first drive motor 1, so that the output end of the first servo motor 1 can be positioned in the initial state.

[0030] The positioning method is as follows: on an idle workstation, a longitudinal positioning axis 5 is set to fix the turntable 2 to the top plate 4. Since the workstations on the turntable 2, including the idle workstations and the processing workstations, are all set with the same gap, as long as the position of the idle workstation is determined, the relationship between the turntable 2 and the first servo motor 1 is determined.

[0031] The workstation of the actuator must also be positioned with each mold 3 on the turntable 2, and the origin position of the first servo motor 1 is determined. Due to the setting of the main control system, the first servo motor 1 and the host have a synchronous operation relationship, that is, the first servo motor 1 and the second servo motor will also run synchronously at intervals.

[0032] The cup-ejection station serves as the origin, aligning it with the position of the top plate positioning hole 41 on the top plate 4. This allows the stations of each actuator to align with the mold 3 above. In particular, achieving synchronization between the upper and lower parts is crucial for the stations of the bottom rolling device 73 and the knurling device 74.

[0033] For the mother mold, there is an upward-pushing optical axis at the cup ejection station to eject the cup. This optical axis can be a longitudinal positioning axis 5, or a separate longitudinal positioning axis 5 can be provided. A flange can be made for the longitudinal positioning axis 5 to pass through for positioning. When the longitudinal positioning axis 5 is pushed upward, the position of the servo motor driving the longitudinal positioning axis 5 is determined. This servo motor coordinates with other second servo motors and first servo motor 1 in terms of position and processing interval synchronization. The second servo motor is connected to the main unit, and the second servo motor drives the various actuators through the mechanical transmission, thereby achieving coordinated action with the first servo motor 1, which is also connected to the main unit, improving the synchronization of the paper cup machine's operation.
