Description

Technical Field

[0001] The present application relates to the technical field of paper tableware production equipment, and in particular to a fully automatic production device for paper cup lids. Background Art

[0002] Paper cups are a common disposable container, usually used to hold beverages such as coffee, tea, and water. Paper cups used in milk tea shops, coffee shops, and other beverage shops are equipped with paper cup covers to prevent the beverages in the paper cups from spilling.

[0003] At present, the production equipment of paper cup lids mainly includes pulp molding machines, trimming machines and manipulators. The pulp molding machine is used to realize the three steps of pulping, adsorption molding and drying and shaping. Among them, the pulping step is mainly to mix waste paper and other raw materials to prepare the pulp of the paper cup lid; the adsorption molding step is mainly to extrude the pulp into the prototype of the paper cup lid through a mold; the drying and shaping step is mainly to remove the moisture in the prototype of the paper cup lid by hot pressing and extrude the paper cup lid into shape. The trimming machine is used to realize the shaping step, which is mainly to cut the paper cup lid after processing by the pulp molding machine and correct the shape of the paper cup lid. The manipulator is used for the unloading of the paper cup lid in the pulp molding machine, the transportation of the paper cup lid in the pulp molding machine, and the loading and unloading of the paper cup lid in the slicer. Therefore, with the cooperation of the pulp molding machine, the trimming machine and the manipulator, the fully automatic production of paper cup lids can be realized.

[0004] Regarding the above-mentioned related technologies, during the working process of the trimming machine, after the trimming machine cuts off the excess part of the edge of the paper cup cover, the remaining waste paper, paper scraps and other impurities will adhere to the trimming machine. For places with high processing accuracy requirements, the presence of these impurities is easy to adhere to the paper cup cover to be processed, and even cause the paper cup cover to be processed to be deformed such as bulges, which will affect the processing accuracy of the paper cup cover. Summary of the invention

[0005] The present application provides a fully automatic production device for paper cup covers, the purpose of which is to promptly remove waste paper and paper scraps remaining in a trimming machine after the paper cup covers are trimmed and shaped during the fully automatic production process of the paper cup covers, thereby improving the processing accuracy of the paper cup covers.

[0006] The fully automatic production device for paper cup lids provided in this application adopts the following technical solution: A fully automatic production device for paper cup lids, comprising a pulp molding machine, a trimming machine, a feeding platform and a conveying mechanism, wherein the pulp molding machine, the trimming machine and the feeding platform are arranged around the conveying mechanism; the conveying mechanism comprises a conveying manipulator, one end of which is rotatably connected to a double-layer suction plate, one side of the double-layer suction plate is provided with a first suction cup group for sucking paper cup lids, and the other side is provided with a second suction cup group for sucking waste paper, the conveying manipulator is provided with a suction cup power source, and the first suction cup group and the second suction cup group are both connected to the suction cup power source through a hose; the trimming machine is provided with a waste paper collecting mechanism, and the waste paper collecting mechanism comprises a waste paper box, the waste paper box is located on the side of the trimming machine facing the conveying manipulator, and the opening of the waste paper box is arranged on the upper side of the waste paper box.

[0007] By adopting the above technical solution, firstly, the pulp molding machine realizes the production of paper cup lids, the trimming machine realizes the trimming and shaping of paper cup lids, the unloading platform realizes the stacking of paper cup lids, and the conveying mechanism realizes the transfer of paper cup lids between the pulp molding machine, the trimming machine and the unloading platform. This can realize the fully automatic production of paper cup lids.

[0008] Secondly, the transport mechanism is configured by the cooperation of the transport manipulator, the double-layer suction plate, the first suction cup group and the suction cup power source. When transporting the paper cup lid, the transport manipulator inserts the double-layer suction plate into the corresponding pulp molding machine or trimming machine, the suction cup power source works, and the first suction cup group absorbs the paper cup lid, which enables the transport mechanism to transport the paper cup lid. Since the double-layer suction plate is rotatably connected to the transport manipulator, the transport manipulator can drive the double-layer suction plate to rotate, which enables the paper cup lid to be stacked on the unloading platform.

[0009] On this basis, since a second suction cup group is also provided on the double-layer suction plate, after the transport mechanism sucks the paper cup lid, the double-layer suction plate is rotated so that the second suction cup group can suck the waste paper remaining in the trimmer. At this time, the suction cup power source works, which enables the second suction cup group to suck the waste paper. Therefore, the coordination of the first suction cup group and the second suction cup group enables the transport mechanism to transport the paper cup lid and the waste paper at the same time.

[0010] The waste paper collecting mechanism is provided with a waste paper box, and when the transporting mechanism is transporting the waste paper, the transporting mechanism can put the waste paper into the waste paper box, thus realizing the collection of the waste paper.

[0011] Therefore, the present application can transport waste paper at the same time when transporting paper cup lids through the setting of the conveying mechanism and the waste paper collecting mechanism, and transport the waste paper from the trimmer to the waste paper box, which can timely remove the waste paper remaining in the trimmer and improve the processing accuracy of the paper cup lids.

[0012] Optionally, the trimming machine includes a working platform, a lower cutting die group and an upper cutting die group, the upper cutting die group is located above the lower cutting die group, the lower cutting die group and the upper cutting die group are arranged opposite to each other in the vertical direction, and the lower cutting die group is arranged on the working platform; a trimming drive assembly is arranged on the working platform, the trimming drive assembly is connected to the upper cutting die group, and the trimming drive assembly is used to drive the upper cutting die group to move in the vertical direction; the trimming machine also includes an adsorption and separation assembly, the adsorption and separation assembly is arranged on the upper cutting die group, and the adsorption and separation assembly is used to adsorb the paper cup lid.

After the paper cup cover is transferred to the trimming machine, the trimming drive assembly drives the upper cutting die set and the lower cutting die combination die, thereby realizing the trimming and shaping processing of the paper cup cover.

[0014] Since the upper cutting die set is provided with an adsorption and separation component, after the paper cup cover is trimmed and shaped, the upper cutting die set and the lower cutting die set are molded, the paper cup cover is adsorbed on the upper cutting die set, and the waste paper remains on the lower cutting die set, thus realizing the separation of the paper cup cover and the waste paper.

[0015] Optionally, the waste paper collection mechanism further includes a suction component, which includes a suction power source and a suction air pipe. A suction air hole is provided at the bottom of the waste paper box. One end of the suction air pipe is connected to the suction air hole, and the other end is connected to the suction power source.

[0016] By adopting the above technical solution, the suction assembly is arranged by the cooperation of the suction power source and the suction air pipe. When the suction power source is working, the suction air pipe is connected with the suction air hole, which makes the opening of the waste paper box have suction. When the transport mechanism puts waste paper into the waste paper box, the waste paper box can suck the waste paper to prevent the waste paper box from floating away.

[0017] Optionally, an isolation plate is provided in the waste paper box, and the isolation plate closes the suction air hole; the isolation plate is spaced apart from the bottom of the waste paper box, and a plurality of ventilation holes are penetrated through the isolation plate.

[0024] By adopting the above technical solution, the scrap suction mechanism cooperates with the scrap suction head and the scrap suction pipe. When the waste paper box is hidden in the working platform, the suction power source works, which makes the scrap suction holes on the scrap suction head have suction force. The scrap suction head is located on the upper side of the lower cutting die set. Under the drive of the scrap suction drive assembly, the scrap suction holes on the scrap suction head can suck the scraps and waste paper on the lower cutting die set into the waste paper box, so as to collect the scraps and waste paper.

[0025] Optionally, a chip suction groove is provided on the inner side wall of the pulling groove, and the chip suction groove is connected to the waste paper box; one end of the chip suction pipe is connected to the working platform, and the chip suction pipe is connected to the chip suction groove.

Under the drive of the lifting drive member, the lifting plate can drive the scrap suction head to rise to the upper side of the lower cutting die group, and then under the drive of the horizontal drive member, the scrap suction head moves through the lower cutting die group, and then can suck the paper scraps and waste paper on the entire lower cutting die group. Through the cooperation of the lifting drive member and the horizontal drive member, it is possible to prevent the scrap suction head from interfering with the movement of the upper cutting die group.

The length direction of the linear drive member 541 is arranged along the depth direction of the drawing slot 52, the linear drive member 541 is connected to the inner side wall of the drawing slot 52, and the optional connecting member 542 is located between the linear drive member 541 and the waste paper box 51. The optional connecting member 542 includes an electromagnetic plate 5421 and a connecting magnetic plate 5422. The connecting magnetic plate 5422 is arranged on the side wall of the waste paper box 51, and the electromagnetic plate 5421 is arranged on the linear drive member 541. The electromagnetic plate 5421 is attracted to the corresponding connecting magnetic plate 5422.

[0070] Driven by the linear drive assembly 54 , the waste paper box 51 can move in the pull-out slot 52 , so that the waste paper box 51 can be moved between the work platform 21 and the transport robot 41 , and the waste paper box 51 can also be moved to be hidden in the pull-out slot 52 .

[0071] In this embodiment, refer to Fig. 9 and Fig.10 There are two sets of linear drive components 54, which are arranged on two opposite inner side walls of the draw-out slot 52. The arrangement of the two sets of linear drive components 54 can improve the stability of the movement of the waste paper box 51.

[0072] In this embodiment, refer to Fig. 9 and Fig.10 Each group of linear drive components 54 is provided with two, and the two linear drive components 541 in the same group are arranged at intervals along the vertical direction, and the two optional connecting components 542 are arranged at intervals along the depth direction of the drawing groove 52.

[0073] Reference Fig.10 and Fig.11 When the waste paper box 51 is hidden in the drawer slot 52 , the two connecting magnetic plates 5422 on the same side of the waste paper box 51 are both arranged opposite to the corresponding electromagnetic plates 5421 .

[0074] Under the action of the two linear drive components 54, when one optional connection member 542 establishes the connection between the corresponding linear drive member 541 and the waste paper box 51, the other optional connection member 542 disconnects the connection between the corresponding linear drive member 541 and the waste paper box 51. Then, one linear drive member 541 can drive the waste paper box 51 to move to the side of the working platform 21 facing the handling robot 41, and the other linear drive member 541 can drive the waste paper box 51 to move to the side of the working platform 21 away from the handling robot 41.

[0075] Reference Fig.12 A chip suction groove 521 is provided on the upper side wall of the pull-out groove 52 . When the waste paper box 51 is hidden in the pull-out groove 52 , the chip suction groove 521 is communicated with the waste paper box 51 .

[0076] Reference Figure 8 and Fig.12The working platform 21 is also provided with a chip suction mechanism 6, which includes a chip suction head 61, a chip suction pipe 62 and a chip storage barrel 63. The chip suction head 61 is located on the upper side of the lower cutting die set 23, and the length direction of the chip suction head 61 is perpendicular to the depth direction of the drawing groove 52. A chip suction hole 611 is provided on the lower side of the chip suction head 61, and the length direction of the chip suction hole 611 is provided along the length direction of the chip suction head 61. The chip storage barrel 63 is located in the chip suction groove 521, and the chip storage barrel 63 is axially provided along the length direction of the drawing groove 52. The chip storage barrel 63 is detachably connected to the inner side wall of the chip suction groove 521, and a plurality of air permeable micropores 631 are provided on the chip storage barrel 63. One end of the chip suction pipe 62 is connected to the chip suction head 61, and the chip suction pipe 62 is communicated with the chip suction hole 611; the other end of the chip suction pipe 62 is connected to the side wall of the working platform 21, and one end of the chip suction pipe 62 extends into the chip suction groove 521, and the chip suction pipe 62 is communicated with the chip storage barrel 63.

[0077] By driving the waste paper box 51 into the hidden pull-out slot 52 through the linear drive assembly 54, the suction power source 531 starts working. At this time, the chip suction holes 611 on the chip suction head 61 can absorb paper scraps and waste paper on the lower cutting die group 23, and then the sucked paper scraps and waste paper enter the chip storage barrel 63 through the chip suction pipe 62.

[0078] Reference Figure 8 and Fig.12 , the chip suction mechanism 6 also includes a chip suction drive assembly 64, which includes a lifting plate 641, a lifting drive member 642, and a horizontal drive member 643. The lifting plate 641 is arranged on the working platform 21, and the length direction of the lifting plate 641 is arranged along the depth direction of the drawing groove 52, and the lifting plate 641 is slidably connected with a plurality of columns 26 along the vertical direction. The lifting drive member 642 is arranged in the working platform 21, and the driving direction of the lifting drive member 642 is arranged along the vertical direction, and the driving end of the lifting drive member 642 is connected to the lifting plate 641. The horizontal drive member 643 is arranged on the lifting plate 641, and the driving direction of the horizontal drive member 643 is arranged along the length direction of the lifting plate 641, and one end of the length direction of the chip suction head 61 is connected to the horizontal drive member 643. In this embodiment, the lifting drive member 642 and the horizontal drive member 643 are both cylinders.

[0079] Driven by the lifting drive member 642, the lifting plate 641 can drive the chip suction head 61 to rise to the upper side of the lower cutting die group 23, and then driven by the horizontal drive member 643, the chip suction head 61 moves through the lower cutting die group 23, and can then absorb the paper scraps and waste paper on the entire lower cutting die group 23.

[0080] In this embodiment, refer to Figure 8 and Fig.12There are two lifting plates 641, which are spaced apart along their width direction, and the chip suction head 61 is located between the two lifting plates 641. A lifting driving member 642 is provided below each lifting plate 641, and a horizontal driving member 643 is provided on each lifting plate 641. This can improve the stability of the movement of the chip suction head 61.

[0081] The implementation principle of the embodiment of the present application is: when the trimmer 2 is working, the lifting drive member 642 lowers the lifting plate 641, and the horizontal drive member 643 moves the chip suction head 61 away, which can prevent the chip suction head 61 from interfering with the operation of the trimmer 2.

[0082] When it is necessary to remove the paper scraps and waste paper on the lower cutting die group 23 by suction, the lifting drive member 642 raises the chip suction head 61 to above the lower cutting die group 23, and under the drive of the horizontal drive member 643, the chip suction head 61 reciprocates on the lower cutting die group 23. At this time, the suction power source 531 works, and the paper scraps and waste paper on the lower cutting die group 23 are sucked into the chip storage barrel 63.

[0083] When the waste paper after the paper cup cover is processed and shaped is relatively soft, the scrap suction mechanism 6 can be directly used to collect the waste paper and paper scraps. When the waste paper after the paper cup cover is processed and shaped is relatively hard, the conveying mechanism 4 is used to convey the waste paper, and the waste paper box 51 is used to store the waste paper; while the scrap suction mechanism 6 only sucks and collects the paper scraps.

[0084] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
