Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the automation feeding technical field of printing equipment, specifically relates to a turnover feeding mechanism and feeding device. BACKGROUND
[0002] At present, plastic containers (such as plastic cup, plastic bowl) have gradually adopted automatic feeding mode when printing on the surface. But the existing feeding mechanism cannot meet the needs of diversification specifications, and different specifications of plastic containers need different specifications of feeding mechanism, for example, the feeding mechanism of plastic bowl is different from the feeding mechanism of plastic cup.
[0003] Therefore, some manufacturers adopt modular feeding mechanism, for example, replace different containers (transfer hopper) to adapt to different specifications of containers. Although this method provides certain flexibility for production line, but in actual application, the replacement cost and time consumption of containers are large, and frequent replacement of a large number of containers will also increase the maintenance work and inventory management requirements. UTILITY MODEL CONTENT
[0004] The utility model provides a turnover mechanism and feeding device to solve the problem that automatic feeding equipment in the prior art is difficult to be compatible with different specifications of plastic containers.
[0005] To solve the above technical problems, the utility model adopts the technical scheme of providing a turnover feeding mechanism arranged on a feeding frame, the feeding frame has a plurality of feeding trays capable of circulating feeding, and the turnover feeding mechanism comprises: a feeding table, a turnover hopper and a driving piece.
[0006] The feeding table is arranged between the feeding frame and the feeding table along the first direction; the turnover hopper is located between the feeding frame and the feeding table along the first direction; and the driving piece is connected with the turnover hopper and is used for driving the turnover hopper to rotate along the clockwise direction or the counterclockwise direction.
[0007] The technical scheme provided by the utility model has the beneficial effects compared with the prior art:
[0008] By arranging the turnover hopper driven to rotate by the driving piece between the feeding table and the feeding frame, when conveying, the plastic containers (such as plastic cups or plastic bowls) arranged in series are fed into the turnover hopper from the feeding table, then the driving piece drives the turnover hopper to rotate to transfer the plastic containers to the feeding tray of the feeding frame, and finally the feeding tray is conveyed to the next process (such as printing process); the above steps are continuously cycled to realize continuous feeding operation.
[0009] When the turnover hopper is turned to the side of the feeding table, the opening of the turnover hopper matches the table surface of the feeding table, and the plastic container can smoothly enter the turnover hopper; when the turnover hopper is turned to the side of the feeding rack, the turnover hopper is configured to be open to match the feeding tray, so that the plastic container located in the turnover hopper can smoothly enter the feeding tray. Wherein, through the feeding tray, the continuously circulating feeding step can be performed, which can adapt to different specifications of plastic containers, and compared with the current transfer mode of the container (such as a hopper), the edge of the plastic container is avoided to be in contact with the container.
[0010] In addition, the above-mentioned turnover feeding mechanism can be applied to the current various specifications of the feeding unit, so as to transform the general feeding unit (for a specific specification of plastic container) into a universal feeding unit (for multiple specifications of plastic container), thereby greatly improving the feeding efficiency while reducing the structural cost of the production equipment.

[0014] With the above technical solution, the telescopic support can set the inclination angle of the feeding table and provide additional support force for the feeding table, so that the feeding table is more stable. Wherein, the inclination of the feeding table can make the plastic container in the feeding table slide into the turnover hopper under the action of gravity, and adjusting the inclination angle of the feeding table through the telescopic support can adjust the sliding speed of the plastic container in the feeding table.
[0015] In some embodiments, the feeding table is provided with a chute extending along the first direction at the bottom thereof in the second direction, and one end of the telescopic support is located in the chute and fixedly connected with the chute. By adopting the above technical scheme, the chute is arranged at the bottom of the feeding table, so that the telescopic support can adjust the connection position with the feeding table.

[0017] By adopting the above technical scheme, the mounting support is sequentially provided with the rotating shaft and the fixed shaft, so that the turnover hopper and the feeding table are sequentially connected.
[0018] In some embodiments, the mounting support further comprises a guide rail and a sliding block capable of slidingly fitting, and the guide rail is fixedly arranged on the feeding frame.
[0019] By adopting the above technical scheme, the fixed position of the mounting support on the feeding frame can be adjusted by arranging the guide groove and the sliding block, and the turnover hopper and the feeding table are both fixed by the mounting support, so that the mounting support can drive the turnover hopper and the feeding table to be adjusted up and down as a whole when the mounting support is adjusted up and down.
[0020] In some embodiments, a shielding baffle is fixedly arranged below the mounting support in the second direction. In this way, the electronic devices are prevented from being exposed, safety is provided, and the feeding frame is kept clean and beautiful.
[0021] In some embodiments, the driving member is fixedly arranged on the mounting support, and the driving member is a pneumatic cylinder.
[0022] In some embodiments, the feeding table is further provided with a baffle on both sides thereof in the third direction, so as to prevent the plastic containers from sliding off the outer edge of the feeding table when the plastic containers slide in the feeding table.
[0023] In some embodiments, the feeding frame comprises a conveying mechanism, and the conveying mechanism is arranged in an inclined manner along the vertical direction, and a plurality of the feeding plates are arranged on the conveying mechanism.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0037] For the convenience of subsequent description, before the specific structure of the turnover feeding mechanism and the feeding device is described, the present application first defines the first direction (X), the second direction (Z) and the third direction (Y) in combination with Figure 1 The first direction is the length direction when the turnover feeding mechanism is normally placed, for example, the X direction; the second direction is the height direction when the turnover feeding mechanism is normally placed, for example, the Z direction; and the third direction is the width direction when the turnover feeding mechanism is normally placed, for example, the Y direction. In the present application, the first direction (X), the second direction (Z) and the third direction (Y) are perpendicular to each other.
[0038] It can be understood that the perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity (for example, the included angle between two structural features is 89.9°) caused by processing errors and assembly errors is also within the range of the perpendicularity in the present application.
[0039] Referring to Figures 1-2 , a three-dimensional structural schematic Figure 1 of an embodiment of the turnover feeding mechanism of the present application is shown. Figure 1 ; Figure 2 A three-dimensional structural schematic of an embodiment of the feeding device of the present application is shown.
[0040] In some embodiments, the turnover feeding mechanism, the feeding rack 10 has a plurality of feeding trays 11 capable of circulating feeding, including a feeding table 20, a turnover hopper 30 and a driving member 40.

[0044] In addition, the above overturning feeding mechanism can be applied to current various specifications of feeding units, so that a general feeding unit (for a specific specification of plastic containers) is modified into a universal feeding unit (applicable to plastic containers of multiple specifications), thereby greatly improving the feeding efficiency while reducing the structural cost of the production equipment.
