[0002] Existing automated paper cup production equipment needs to ensure that the production rhythm of different workstations is coordinated and consistent. It usually uses multiple coaxial cams as the power source, and requires multiple transmission components to connect the cams with the devices of each workstation. Such equipment has a complex structure. When one of the workstations fails, it often causes the entire equipment to stop working, and the maintenance cost is high. In addition, the cam transmission method is noisy, wears high, and the transmission speed is difficult to increase. In addition, the load rate of the drive motor is large and easy to damage. The long-term use cost is high, which is not conducive to improving the production capacity of the paper cup production line. Utility Model Content

[0008] A cup bottom processing device, comprising a cup bottom processing body located below the first turntable and a third servo drive assembly installed on the chassis and drivingly connected to the cup bottom processing body; and

[0009] The cup mouth processing device comprises a cup mouth processing body located above the second turntable and a fourth servo drive component installed on the mounting plate and drivingly connected to the cup mouth processing body.

[0010] With such an arrangement, four main devices of the paper cup production equipment are driven respectively by four servo drive components, thereby reducing the load rate of a single servo drive component. On the basis of ensuring the tight coordination of the four main devices, the production speed of the paper cup production equipment is increased, the operating fault tolerance of the paper cup production equipment is increased, and maintenance and replacement are convenient. At the same time, installing the fourth servo drive component connected to the cup mouth processing device on the mounting plate above the chassis also releases the space inside the chassis, thereby reducing the size of the chassis, so that the space occupied by the entire paper cup production equipment is reduced, which is beneficial to saving factory space.

[0011] In one embodiment, the first servo drive assembly includes a rotating shaft fixedly connected to the first turntable and a DD motor installed on the chassis, the DD motor is drivingly connected to the rotating shaft, the mounting plate has a limiting hole, and the rotating shaft is rotatably inserted into the limiting hole.

[0012] Such an arrangement is conducive to reducing the shaking of the first turntable and ensuring the stability and accuracy of rotation.

[0013] In one embodiment, a vertical projection of at least one of the second paper cup molds overlaps with the first paper cup mold.

[0014] With such arrangement, the paper cup located in the first paper cup mold can be directly dropped into the second paper cup mold without the need for an additional transfer device, thereby further reducing the occupied space of the paper cup production equipment.

[0015] In one embodiment, the cup bottom processing body includes a first synchronization plate and two hot air mechanisms, a bottom rolling mechanism, a knurling mechanism and a plurality of guide rods fixedly connected to the first synchronization plate, and the frame also includes a plurality of first bearing seats fixedly connected to the chassis, and the guide rod can be slidably inserted in the first bearing seat.

[0016] Such an arrangement increases the synchronization and stability of the vertical movement of the hot air mechanism, the bottom rolling mechanism and the knurling mechanism, which is beneficial to increasing the connection quality between the cup bottom and the cup tube.

[0017] In one embodiment, the hot air mechanism includes a heating seat, a heater arranged vertically and located at the lower end of the heating seat, and an air intake pipe connected to the lower end of the heater. The chassis is also provided with an avoidance hole, and the air intake pipe is passed through the avoidance hole.

[0018] With such an arrangement, the air intake pipe can extend from the avoidance hole without bending, thus ensuring the stability of the air intake and preventing damage to the air intake pipe.

[0021] In one embodiment, the paper cup production equipment further includes a paper feeding device, a leaf holding device, a paper feeding hook mechanism located between the paper feeding device and the leaf holding device, and a cup feeding tube mechanism located between the leaf holding device and the first shifting device.

[0022] With such arrangement, the paper sheets and cup tubes are transported through the paper feeding hook mechanism and the cup tube feeding mechanism, thereby improving the production continuity of the paper cup production equipment.

[0023] In one embodiment, the mounting plate is provided with a first mounting hole and a second mounting hole, and the paper cup production equipment further includes a detection device, a first guide tube inserted in the first mounting hole, and a second guide tube inserted in the second mounting hole, and the first guide tube and the second guide tube are respectively covered on different second paper cup molds for guiding the paper cup located in the second paper cup mold to escape.

[0024] With such arrangement, the first mounting hole and the second mounting hole provide two outlets for the paper cup production equipment. After being inspected by the inspection mechanism, the paper cups are divided into waste cups and normal cups, and are transported through the first guide tube and the second guide tube respectively, thereby realizing the diversion of paper cups and improving the production quality of finished paper cups. The mounting plate also provides an installation platform for the first guide tube and the second guide tube to prevent the guide tubes from shaking.

[0025] In one embodiment, the paper cup production equipment includes an air blowing mechanism, which is fixedly connected to the chassis and is used to blow out the paper cup located in the second paper cup mold.

[0026] With such arrangement, the air blowing effect of the air blowing mechanism enables the paper cup located in the second paper cup mold to have initial kinetic energy, which facilitates the paper cup to quickly enter the first guide tube and the second guide tube, thereby preventing the finished paper cup from clogging the second turntable.

[0027] The present application also provides a paper cup production line, comprising:

[0029] A plurality of paper cup production devices as described above; and

[0030] A plurality of negative pressure transmission pipelines, both ends of which are respectively connected to the paper cup collecting device and the paper cup production equipment.

[0031] Such arrangement, since the paper cup production equipment provided by the present application occupies less space, is conducive to expanding the scale of the production line, allowing more paper cup production equipment to be arranged in the same factory building, thereby increasing the production capacity of the production line. At the same time, the operating devices of the main functions are easy to repair and replace, which is conducive to reducing the maintenance cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Existing automated paper cup production equipment needs to ensure that the production rhythm of different workstations is coordinated and consistent. It usually uses multiple coaxial cams as the power source, and requires multiple transmission components to connect the cams with the devices of each workstation. Such equipment has a complex structure. When one of the workstations fails, it often causes the entire equipment to stop working, and the maintenance cost is high. In addition, the cam transmission method is noisy, wears high, and the transmission speed is difficult to increase. In addition, the load rate of the drive motor is large and easy to damage. The long-term use cost is high, which is not conducive to improving the production capacity of the paper cup production line.

[0047] Based on this, it is necessary to provide a paper cup production equipment and a paper cup production line which are easy to maintain and have high production efficiency.

[0050] See also Figure 1 The first shifting device 20 includes a first turntable 21, a plurality of first paper cup molds 22 installed on the lower side of the first turntable 21, and a first servo drive assembly 23. The first turntable 21 has a plurality of first paper cup molds 22. The first servo drive assembly 23 is installed on the chassis 11 and is driven and connected to the first turntable 21 to drive the plurality of first paper cup molds 22 to move.

[0051] See also Figure 3 , Figure 3 for Figure 1 The second shifting device 30 includes a second turntable 31 located below the first turntable 21 , a plurality of second paper cup molds 32 installed on the lower side of the first turntable 21 , and a second servo drive assembly 33 installed on the chassis 11 and drivingly connected to the second turntable 31 .

[0052] Please refer again Figure 5 , Optionally, in an embodiment provided by the present application, the vertical projections of the two second paper cup molds 32 overlap with the two first paper cup molds 22, that is, the paper cup can fall from the first paper cup mold 22 to the second paper cup mold 32 in the overlapping area of ​​the two shift disks, thereby entering the next processing step. The first servo drive component 23 drives the first turntable 21 to rotate so that the paper cup located in the first paper cup mold 22 rotates to the overlapping area of ​​the two shift disks, and the second servo drive component 33 drives the second turntable 31 to rotate so that the paper cup dropped to the second paper cup mold 32 rotates out of the overlapping area of ​​the two shift disks.

[0053] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1 The enlarged view of the paper cup production equipment at X is shown. Figure 4 for Figure 3 The paper cup production equipment is shown as a partial enlarged view at Y. The cup bottom processing device 40 includes a cup bottom processing body 41 located below the first turntable 21 and a third servo drive assembly 42 installed on the chassis 11, and the cup mouth processing device 50 includes a cup mouth processing body 51 and a fourth servo drive assembly 52 installed on the chassis 11. Specifically, in an embodiment provided in the present application, the cup bottom processing body 41 includes a first synchronization plate 411 and two hot air mechanisms 412, a bottom rolling mechanism and a knurling mechanism respectively installed on the first synchronization plate 411, and the third servo drive component 42 is driven and connected to the first synchronization plate 411 so that the two hot air mechanisms 412, the bottom rolling mechanism and the knurling mechanism are simultaneously close to the multiple first paper cup molds 22; the cup mouth processing body 51 includes a second synchronization plate 511 and an oiling mechanism 512, an initial rolling mechanism 513 and a final rolling mechanism 514 respectively installed on the second synchronization plate 511, and the fourth servo drive component 52 is driven and connected to the second synchronization plate 511 so that the oiling mechanism 512, the initial rolling mechanism 513 and the final rolling mechanism 514 are simultaneously close to the paper cup located at the second paper cup mold 32.

[0054] A paper cup production equipment in the above embodiment drives four main paper cup processing devices respectively through four servo drive components. Compared with the transmission of multiple processing devices connected to the same driving source through a transmission shaft, the load of the driving source is reduced, thereby increasing the overall load upper limit of the paper cup production equipment, that is, increasing the operating speed of the entire paper cup production equipment, and improving production efficiency. After actual measurement, the normal production speed of the paper cup production equipment provided by the present application is 200 per minute, compared with 160 per minute of the traditional technology, the production efficiency has been greatly improved. In addition, such a setting also reduces the coupling degree between the main paper cup processing devices, so that the operation fault tolerance rate of the entire paper cup production equipment is improved. That is to say, after the equipment has an abnormality, it only needs to replace the main processing device to which the abnormality belongs as a whole, and the production progress of the paper cup will not be affected by maintenance. It is worth noting that the present application fixes the third servo drive assembly 42 connected to the cup mouth processing device 50 to the mounting plate 12 above the chassis 11, which makes disassembly more convenient and also saves space inside the chassis 11, so that the space of the chassis 11 can be reduced. Since there is no need to open a matching hole on the top of the chassis 11 for the installation of the transmission assembly, the possible structural interference between the second shifting device 30 and the transmission assembly is eliminated, the structure and assembly difficulty are simplified, and it is also beneficial to further reduce the occupied space of the entire paper cup production equipment.

In this way, the first mounting hole 121 and the second mounting hole 122 provide two outlets for the paper cup production equipment. After being detected by the detection mechanism 1, the paper cups are divided into waste cups and normal cups, and are transported through the first guide tube 2 and the second guide tube 3 respectively, so as to realize the diversion of paper cups and improve the production quality of the finished paper cups.
