Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only part of the embodiments of the implementation manners of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to the accompanying drawings, in the embodiment of this implementation manner, the oil dipping device with cup mouth pretreatment includes an oil distribution plate 1 and an oil dipping component 2 ( Figure 1 , 3, which is not shown in FIGS. 4. For example, the oil dipping component 2 can be a component that can absorb and dip oil, such as a felt rope, an oil cotton rope, a silicone rubber ring, etc. An installation groove 11 is provided on the oil distribution tray 1, and the oil dipping component 2 is installed and connected to the installation groove 11. The oil dipping component 2 can move together with the oil distribution tray 1 (such as a lifting movement). In addition, the oil distribution tray 1 distributes oil to the oil dipping component 2 for oil supply, so that the oil dipping component 2 dips and lubricates the cup mouth. The oil dipping part 21 is arranged at the outer ring position of the oil dipping component 2. When dipping oil, the oil dipping component 2 will be inserted into the cup mouth, and the oil dipping component 2 will contact the inner wall of the cup mouth for dipping and lubricating. Here, the cup mouth refers to the container mouth of a paper cup 20 or a paper bowl and other paper containers when they are not curled (i.e., curled edge).

[0026] Among them, a pre-rolled edge shaping groove 12 is further provided on the oil distribution tray 1 for preprocessing the cup mouth, performing pre-rolled edge shaping, so that the cup mouth of the paper cup 20 is pre-rolled and curled outward for shaping, facilitating the subsequent curling to be completed smoothly and stably, reducing the waste rate of subsequent curling, and achieving an effective curling forming effect.

[0027] Among them, the pre-rolled edge shaping groove 12 is arranged outside the outer ring position of the oil dipping component 2 (i.e., the outside of the outer ring), and the pre-rolled edge shaping groove 12 is located above the oil dipping part 21 of the oil dipping component 2. During operation, the oil dipping component 2 is relatively inserted into the cup mouth, and the oil dipping part 2 of the oil dipping component 2 contacts the inner wall of the outer ring of the cup mouth for dipping and lubricating. The edge (rim) of the cup mouth will enter the pre-rolled edge shaping groove 12 to complete the pre-rolled edge and outward curling shaping process (i.e., cup mouth preprocessing). During the process of the oil dipping component 2 being relatively inserted into the cup mouth, the oil dipping lubrication of the cup mouth (inner wall) and the cup mouth preprocessing are completed.

[0028] The oil dipping device with cup mouth preprocessing not only has the oil dipping component 2 to cooperate with dipping and lubricating the inner side (inner wall) of the cup mouth, but also has the pre-rolled edge shaping groove 12 to pre-roll the cup mouth and curl it outward for shaping (i.e., preprocessing). During the process of the oil dipping component 2 being relatively inserted into the cup mouth, the oil dipping lubrication of the cup mouth and the cup mouth preprocessing are completed. The combination of them is smoother and more efficient. And after the cup mouth is dipped with oil and preprocessed, the subsequent curling (such as initial curling, final curling, etc.) in the curling forming device will be smoother and more stable.

[0029] Based on the above embodiments respectively, the following optimizations or further explanations can also be carried out.

[0030] For example, among them, the oil dipping device with cup mouth preprocessing further includes an installation rod 3. The oil distribution tray 1 is connected to the installation rod 3, and the oil distribution tray 1 is installed along with the installation rod 3 so as to be installed in the paper cup 20 production equipment; in addition, the installation rod 3 can be a lifting rod so that the entire oil dipping device can be lifted and lowered relatively and inserted into the lower paper cup 20; among them, the pre-rolled edge shaping groove 12 can be a rolling R groove.

[0031] There are multiple ways for the oil distribution plate 1 to supply lubricating oil to the oil dipping component 2. For example, an oil distribution channel 13 is provided on the oil distribution plate 1. The oil distribution channel 13 is connected to the oil inlet 14, and the oil distribution channel 13 is connected to the installation groove 11. Of course, the oil inlet 14 and the installation groove 11 can also be directly connected through a hole or the like. An oil inlet joint 10 can be configured at the oil inlet 14 to facilitate pipeline connection and oil inlet.

[0032] For example, the oil distribution plate 1 includes an upper sealing plate 15 and a main board 16. An oil distribution groove 18 is provided on the main board 16. The upper sealing plate 15 covers the main board 16. The upper sealing plate 15 and the oil distribution groove 18 enclose to form the oil distribution channel 13. The oil distribution channel 13 can be a circular ring structure (such as a circular ring or a square ring, etc.). An oil distribution small hole 19 is also provided on the oil distribution plate 1. The oil distribution channel 13 is connected to the installation groove 11 through the oil distribution small hole 19. For example, the oil distribution small hole 19 is connected between the oil distribution channel 13 (the oil distribution groove 18) and the installation groove 11. The oil distribution small holes 19 are distributed on the main board 16 (for example, evenly arranged, and the lubricating oil supply to the oil dipping component 2 is relatively more uniform). An oil inlet joint 10 is provided at the oil inlet 14, and the oil inlet joint 10 is installed on the upper sealing plate 15; the upper sealing plate 15 can be an annular plate; in this structure, it is not only convenient for the processing and assembly of the oil circuit structure, but also the oil supply effect is relatively good. In addition, the oil distribution plate 1 further includes a bottom plate 17. The bottom plate 17 is connected below the main board 16. The installation grooves 11 are respectively arranged on the outer circle of the main board 16 and the outer circle of the bottom plate 17. The main board 16 and the bottom plate 17 enclose to form the installation groove 11 from top to bottom, which is convenient for the processing and production of the installation groove 11. The bottom plate 17 can be installed and connected through fasteners (such as screws, etc.), and can be directly connected to the main board 16 or the installation rod 3, etc. In addition, the pre-rolled edge shaping groove 12 is provided on the oil distribution plate 1 (such as the main board 16). When adapting to a square paper cup 20, the pre-rolled edge shaping groove 12 can be correspondingly arranged at the straight edge (long side and short side, etc.) position of the paper cup 20.

[0033] In addition, an oil receiving tray 4 is connected and configured below the oil distribution plate 1. The upper side of the oil receiving tray 4 has an oil receiving cavity 22. The oil receiving tray 4 can catch and store the lubricating oil that overflows from the oil dipping component 2 and / or the installation groove 11 and drips down along the oil distribution plate 1 in the oil receiving cavity 22, avoiding the lubricating oil from dripping onto the paper cup 20 or the equipment and avoiding the waste of lubricating oil.

[0034] In addition, an oil pumping component 5 is provided above the oil receiving tray 4. The oil pumping component 5 is connected to the oil distribution plate 1. The oil pumping component 5 pumps away the lubricating oil collected in the oil receiving tray 4. Among them, the oil pumping port 6 of the oil pumping component 5 is located below the oil distribution plate 1. For example, the oil pumping component 5 uses an oil pumping rod or an oil pumping pipe; a oil collecting concave part 23 is also provided in the oil receiving cavity 22 of the oil receiving tray 4, and the oil pumping port 6 is located above the oil collecting concave part 23, which can make the lubricating oil gather and be pumped more smoothly.

[0035] The outer periphery of the oil receiving tray 4 (i.e., the outer ring position) has a lining pressing cup part 24, and the lining pressing cup part 24 can be cooperatively lined and pressed inside the mouth of the paper cup 20 to press the body of the paper cup 20, so as to support the paper cup 20 for cup mouth lubrication and pretreatment; moreover, the oil receiving tray 4 can be additionally arranged to be lifted and floated on the oil distribution tray 1. The oil receiving tray 4 can first contact the body of the paper cup 20 with the lining pressing cup part 24, press the body of the paper cup 20, support the paper cup 20 and then perform cup mouth lubrication and pretreatment successively, making the cup mouth lubrication and pretreatment (i.e., pre-rolling the cup mouth and curling and shaping it outward) smoother and more stable; for example, a spring 7 is provided between the oil receiving tray 4 and the oil distribution tray 1, so that the oil receiving tray 4 is lifted and floated relative to the oil distribution tray 1 through the spring 7. The spring 7 can play a role in separating, pre-tightening and buffering the oil receiving tray 4 and the oil distribution tray 1. A screw 25 can be provided on the oil receiving tray 4. The screw 25 passes through the through hole 26 of the oil distribution tray 1, and the head of the screw 25 is located above the oil distribution tray 1. The spring 7 is sleeved on the screw 25.

[0036] In addition, there is also a cup discharging air blowing port 8, and the cup discharging air blowing port 8 is arranged on the lower side of the oil receiving tray 4 to separate the paper cup 20 after the cup mouth lubrication and pretreatment are completed. In order to avoid the situation that the lining pressing cup part 24 of the oil receiving tray 4 presses the cup body and cannot be separated smoothly, the paper cup 20 is separated by blowing air through the cup discharging air blowing port 8, and the paper cup 20 is separated from the oil dipping device smoothly.

[0037] The cup discharging air blowing port 8 is inclined towards the cup wall and / or downward towards the cup bottom; when it is inclined towards the cup wall, it can expand the cup body opening to separate from the oil receiving tray 4 (lining pressing cup part 24) and loosen and fall off without easily damaging (such as scratching) the paper cup 20; when it is downward towards the cup bottom, the paper cup 20 is directly separated by blowing air.

[0038] For example, a blowing hollow rod 9 is connected to the oil receiving tray 4, and the blowing hollow rod 9 is connected to the cup discharging air blowing port 8 (such as a nozzle, etc.) or the cup discharging air blowing port 8 is arranged at the lower end of the blowing hollow rod 9. A passage is provided on the oil distribution tray 1 for the blowing hollow rod 9 to pass through; the blowing hollow rod 9 is arranged vertically; it is convenient for the oil receiving tray 4 to float relative to the oil distribution tray 1 (lift and lower). It can also be optimized that an exhaust passage 29 is also provided on the oil distribution tray 1 for exhausting air to avoid the extreme situation that the paper cup 20 is damaged by suffocation during the oil dipping process; the exhaust passage 29 serves as a passage for the blowing hollow rod 9 to pass through, and an exhaust gap 30 is left between the blowing hollow rod 9 and the passage.
