Description

Technical Field

[0001] The present invention relates to the technical field of paper cup production, and in particular to a positioning device for producing and processing disposable paper cups. Background Art

[0002] Disposable paper cups are disposable containers primarily made of paper and used to hold beverages or other liquids. They are widely used in homes, offices, and catering services. Made from food-grade wood pulp paper, they typically have a waterproof coating on the inside to prevent leakage. Their core features are ease of use, affordability, and compliance with hygiene standards, avoiding the risk of cross-contamination from repeated use.

[0003] In the existing production of disposable paper cups, it is necessary to first cut the base paper into a predetermined shape, then perform lamination and printing on the cut base paper, and then roll the cup and glue it. After gluing, the rolled cup body is curled at the cup mouth, and then the cup body and the cup bottom are connected and sealed to realize the production of disposable paper cups. In the paper cup production process, the cup body and bottom sealing process is particularly important.

[0004] During the production and processing of existing disposable paper cups, most of them need to support and fix the rolled cup body through air bags, and then position and connect the supported cup body and the cup bottom to realize the bottom sealing process of the cup body. However, when the cup body and the cup bottom are connected, since the inside of the cup body is supported and fixed by the air bags, the angle offset or inaccurate position of the cup body will inevitably occur after it is fixed, which can easily lead to deformation or dislocation of the cup body when it is connected to the cup bottom, making the connection production process unstable, increasing the scrap rate and reducing product quality. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a positioning device for the production and processing of disposable paper cups, which uses a correction piece to adjust the cup body so that the cup body is in a vertical state, avoiding the cup body from tilting when fixed, so that when the cup body and the cup bottom are connected, the two remain in a vertical state, thereby improving the accuracy of the connection between the cup body and the cup bottom.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention fixes the cup body by a rapidly expanding support airbag. Afterwards, the operation of the adjusting member causes the internal components of the adjusting member to drive the two adjusting members, thereby driving the two adjusting members to move toward the cup body, thereby quickly adjusting the position and angle of the cup body, so that the cup body is in a vertical state, preventing the cup body from tilting when fixed, and ensuring that the cup body and the cup bottom remain in a vertical state when docked, thereby improving the docking accuracy of the cup body and the cup bottom, thereby improving the docking efficiency;

[0019] 2. When the adjusting member drives the adjusting member to move, the limiting member can be driven synchronously, so that the internal component of the limiting member extends from one side of the adjusting member and cooperates with the adjusting member to form an annular closed loop that fits the outer wall of the cup body. Then, the limiting member cooperates with the inflated supporting airbag to restrict the cup body, preventing the cup body from wrinkling and distorting due to external force during docking, further improving the docking accuracy between the cup body and the cup bottom, and improving the docking efficiency.

[0020] 3. During the operation of the electric turntable and the electric track, the position of the cup body can be adjusted, and the position of the cup body and the cup bottom extension platform can be visually positioned through the visual detector. During this period, the infrared transmitter can continuously release infrared rays. When the infrared rays released by the two infrared transmitters are received by the two infrared receivers at the same time, the electric turntable and the electric track can stop operating. At this time, the positioning rod corresponds vertically to the positioning slot, and the cup body and the cup bottom are on the same axis, thereby achieving precise positioning of the cup body and the cup bottom, and improving the accuracy of the positioning of the cup body and the cup bottom;

[0021] 4. When the cup bottom extension platform drives the cup bottom to be inserted into the cup body, the positioning rod is inserted into the positioning groove during the movement. When the bottom end of the positioning rod contacts the inner bottom of the positioning groove, the cup bottom reaches the pre-set insertion position, which can realize the precise positioning of the cup body and cup bottom connection position, thereby improving the positioning accuracy. At the same time, when the cup bottom extension platform is over-inserted, the inner bottom of the positioning groove pushes the positioning rod, so that the positioning rod is forced to push the adjusting part and the adjusting part, so that the two are lifted upward, and then the cup body is lifted upward, so that the cup bottom is always maintained in the pre-set insertion position range, thereby improving the accuracy of docking positioning. At the same time, when the positioning rod is subjected to force, the pressure is sensed by the pressure sensor, and then the protective part is activated, so that the internal components of the protective part are quickly expanded and an external support force is formed at the bottom of the paper cup to prevent the bottom of the cup body from curling, wrinkling or breaking when the cup bottom extension platform is over-inserted, further improving the accuracy of docking and improving the production efficiency of paper cups.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0034] See also Figures 1 to 4, which is the first embodiment of the present invention, provides a technical solution: a positioning device for the production and processing of disposable paper cups, comprising a workbench 1, an electric turntable 2 is fixedly connected to one side of the top of the workbench 1, a plurality of electric rails 3 are fixedly connected to the top of the electric turntable 2, and mutually symmetrical elastic telescopic parts 4 are installed on the electric rails 3. The bottom end of the elastic telescopic part 4 is fixedly connected to an adjusting part 5, and the adjusting part 5 is transmission-connected with mutually symmetrical correcting parts 6, and a limiting part 7 is installed on the correcting part 6. The adjusting part 5 is transmission-connected to the limiting part 7. Here, the opposite surfaces of the two correcting parts 6 are arc-shaped and are in an inclined state from top to bottom. The degree of inclination is consistent with the production specifications of the cup body, and the inner arc side of the limiting part 7 is the same structure as the inner arc side of the correcting part 6, and The limiting part 7 is connected with the inner arc side of the adjusting part 6 to form a smooth plane, which can form a seamless fit with the outer wall of the cup body. The middle of the bottom of the adjusting part 5 is fixedly connected with a supporting airbag 8, and the top of the supporting airbag 8 can be connected to an external air pump. The supporting airbag 8 is quickly inflated by the air pump, so that the supporting airbag 8 bulges in the cup body, and then the inflation is used to support the inner wall of the cup body to fix the cup body. When the cup body is separated, the internal gas of the supporting airbag 8 can be partially extracted by the external air pump, so that a gap is formed between the supporting airbag 8 and the inner wall of the cup body. Under the action of gravity, the cup body falls, and the cup body can be separated. After inflation, the supporting airbag 8 is conical, which matches the structure of the inner wall of the cup body, and a visual inspection device is installed on one side of the adjusting part 5. Detector 14, through the visual detector 14, the cup bottom extension platform 11 and the cup body position on the supporting airbag 8 can be detected, and then the electric turntable 2 and the electric track 3 are cooperated to move the cup body to the top of the cup bottom extension platform 11, and vertically correspond to it. The bottom of the adjusting member 6 is fixedly connected with a protective member 10, and a positioning rod 9 is installed on the protective member 10. The top side of the protective member 10 is fixedly connected with a pressure sensor 13, and the bottom side of the protective member 10 is fixedly connected with an infrared receiver 12. One end of the positioning rod 9 is in contact with the sensing end of the pressure sensor 13. Here, a controller is provided on the top of the adjusting member 5, and the pressure sensor 13 can detect the pressure on the positioning rod 9 and send a signal to the controller. After that, the controller is used to The protective part 10 is started, and a cup bottom extension platform 11 is installed on one side of the top of the workbench 1. Positioning grooves 15 are provided on both sides of the cup bottom extension platform 11, and the position of the cup bottom inserted into the cup body can be preset. When the bottom end of the positioning rod 9 reaches the bottom of the positioning groove 15, the cup bottom reaches the set position. Infrared transmitters 16 are installed on both sides of the top of the cup bottom extension platform 11. Infrared rays are released through the infrared transmitter 16. When the infrared receiver 12 is vertically aligned with the infrared transmitter 16, the infrared receiver 12 receives the infrared rays. At this time, the cup body and the cup bottom extension platform 11 are in a vertically aligned state, and the electric turntable 2 and the electric track 3 stop driving, thereby achieving precise alignment of the cup body and the cup bottom on the cup bottom extension platform 11;

[0035] The cup body is fixed by inflating the supporting airbag 8, and the two adjusting parts 6 are driven by the adjusting part 5 to move toward the cup body and adjust the angle and position of the cup body. During the movement of the adjusting part 6, the limit part 7 is stretched by the force of the adjusting part 5 and fits the side wall of the cup body. After that, the electric turntable 2 drives the electric track 3 and the adjusting part 5 to rotate, and drives the infrared receiver 12 to move. When the infrared receiver 12 receives the infrared ray released by the infrared transmitter 16, the electric turntable 2 stops rotating. At this time, the cup body and the cup bottom extension platform 11 are on the same axis, and the positioning of the cup body and the cup bottom can be completed.

[0036] The adjusting member 5 includes a connecting seat 51 fixedly connected to the bottom end of the elastic telescopic member 4, and inner grooves 54 are provided on both sides of the connecting seat 51. A bidirectional threaded rod 53 is rotatably connected to the inside of the connecting seat 51. A motor 52 is fixedly connected to one side of the connecting seat 51, and the output end of the motor 52 is fixedly connected to one end of the bidirectional threaded rod 53. A rack 55 is fixedly connected to one side of the inner groove 54.

[0037] The adjusting member 6 includes a driving block 63 that is slidably connected to the inside of the inner groove 54. Here, the outer wall of the driving block 63 is smoothed to reduce the friction between the driving block 63 and the inner groove 54 and improve the smoothness during movement. The bottom of the driving block 63 is fixedly connected to a moving column 61, and the driving block 63 is threadedly connected to the bidirectional threaded rod 53. One side of the moving column 61 is fixedly connected to multiple arc-shaped dial plates 62. The inner arc side of the arc-shaped dial plate 62 is inclined from top to bottom and fits the outer wall of the cup body. The upper and lower ends of the arc-shaped dial plate 62 are provided with guide grooves 64.

[0038] When the cup body and the cup bottom are spliced and positioned, the formed cup body can be first transported to the supporting airbag 8 through an external conveying mechanism, and the supporting airbag 8 can be inflated by an external air pump to quickly expand the supporting airbag 8, thereby supporting and fixing the inner wall of the cup body. Afterwards, the position of the fixed cup body is adjusted by the operation of the electric turntable 2 and the electric track 3, and then moved toward the cup bottom top extension platform 11. During this period, the positions of the cup body and the cup bottom top extension platform 11 are visually inspected by the visual detector 14, and the electric turntable 2 and the electric track 3 are used to move the cup body to the top of the cup bottom top extension platform 11. During this period, the electric turntable 2 and the electric track 3 are used to move the cup body to the top of the cup bottom top extension platform 11. During this period, the infrared emitter 16 can continuously release infrared light. External line, when the infrared rays released by the two infrared transmitters 16 are received by the two infrared receivers 12 at the same time, the electric turntable 2 and the electric track 3 can stop running. At this time, the positioning rod 9 corresponds vertically to the positioning groove 15, and the cup body and the cup bottom are on the same axis, so as to achieve precise positioning of the cup body and the cup bottom. Afterwards, through the operation of the cup bottom extension platform 11, the cup bottom is driven to move toward the cup body, and then the cup bottom is driven to be inserted into the cup body. During the movement, the positioning rod 9 is inserted into the positioning groove 15. When the bottom end of the positioning rod 9 reaches the bottom of the positioning groove 15, the cup bottom reaches the preset interval, and the precise positioning of the cup body and the cup bottom insertion position can be achieved.

[0039] When the electric turntable 2 and the electric track 3 drive the cup body to move, the operation of the motor 52 can drive the bidirectional threaded rod 53 to rotate. The rotating bidirectional threaded rod 53 can synchronously drive the two driving blocks 63 to slide inside the inner groove 54, so that the two driving blocks 63 drive the two moving columns 61 to move toward the cup body respectively, and push the arc-shaped dial plate 62 to fit with the outside of the cup body, thereby adjusting the angle and position of the cup body, so that the cup body remains vertically centered under the connecting seat 51, thereby avoiding the cup body from tilting when fixed, so that when the cup body and the bottom of the cup are docked, the two remain in a vertical state, thereby improving the accuracy of the docking between the cup body and the bottom of the cup, thereby improving the docking efficiency. Example 2

[0040] See also Figure 5 and Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the limiting member 7 includes arcuate tooth plates 71 slidably installed between multiple arcuate shift plates 62, and the upper and lower ends of the arcuate tooth plates 71 are fixedly connected to guide plates 72. Here, the inner arc side structure of the arcuate tooth plate 71 is consistent with the arcuate shift plate 62, and the inner arc sides of the two are smoothly connected to form an inclined arc surface that fits the side wall of the cup body. The guide plate 72 is slidably connected in the guide groove 64, and the interior of the movable column 61 is fixedly connected to a driving member, which is transmission-connected to the arcuate tooth plate 71.

[0041] The driving member includes a rotating rod 73 rotatably connected to the inside of the moving column 61, and a plurality of driving gears 74 are fixedly connected to the rotating rod 73. The driving gears 74 are meshed with the arc-shaped tooth plate 71. The top of the moving column 61 is fixedly connected to a gear commutator 75, and the top of the rotating rod 73 is fixedly connected to the gear commutator 75. The side of the gear commutator 75 away from the rotating rod 73 is fixedly connected to a transmission gear 76, and the transmission gear 76 is meshed with the rack 55.

[0042] When the moving column 61 moves, it can drive the limiter 7 to move synchronously, so that the rotating rod 73, the gear commutator 75 and the transmission gear 76 can move synchronously with the moving column 61. During this period, the transmission gear 76 can be driven by the rack 55 when it moves, so that the transmission gear 76 rotates. The rotating transmission gear 76 can use the gear commutator 75 to drive the rotating rod 73 to rotate, and then drive multiple driving gears 74 to rotate, thereby driving multiple arc-shaped toothed plates 71, so that the arc-shaped toothed plates 71 extend from between the two arc-shaped shifting plates 62. When the moving column 61 is in contact with the cup body, this When the arc-shaped tooth plate 71 is extended, a supporting force can be formed on the outer wall of the cup body through multiple arc-shaped tooth plates 71, and a plurality of arc-shaped shift plates 62 are cooperated to form a circular closed loop on the outside of the cup body, and then cooperate with the inflated support airbag 8 to restrict the cup body, to prevent the cup body from being wrinkled and distorted due to external force during docking, and further improve the docking accuracy between the cup body and the cup bottom. When the arc-shaped tooth plate 71 is extended, it can drive the guide plate 72 to slide inside the guide groove 64, and the guide plate 72 can guide and limit the movement of the arc-shaped tooth plate 71 to prevent the arc-shaped tooth plate 71 from offsetting during movement.

[0043] The remaining structures are the same as those of Example 1. Example 3

[0044] See also Figure 6 、 Figure 7 、 Figure 8 and Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that: the protective member 10 includes a connection box 101 fixedly connected to the bottom of the movable column 61, a mounting groove 104 is provided at the inner bottom of the connection box 101, and a support member is installed on one side of the interior of the connection box 101.

[0045] The positioning rod 9 is slidably installed in the installation groove 104, and the end of the positioning rod 9 close to the connecting box 101 is fixedly connected to a limiting plate 91, and the limiting plate 91 is in contact with the port inside the installation groove 104. The pressure sensor 13 is fixedly connected to the top of the connecting box 101, and the sensing end of the pressure sensor 13 is in contact with one side of the limiting plate 91. Here, the limiting plate 91 is placed on the inner top port of the installation groove 104 to limit the positioning rod 9, and the outer side of the positioning rod 9 is smoothed to reduce the friction with the positioning groove 15. The pressure sensor 13 can be set in advance. When the pressure transmitted by the positioning rod 9 reaches the set range, the controller drives the protective member 10 to avoid the phenomenon that the positioning rod 9 generates slight pressure on the pressure sensor 13 when inserted into the positioning groove 15 and activates the protective member 10.

[0046] The elastic telescopic part 4 includes a sleeve rod 41 fixedly connected to the electric track 3, and a spring 42 is fixedly connected to the inside of the sleeve rod 41. The end of the spring 42 away from the sleeve rod 41 is fixedly connected to the inner rod 43, and the end of the inner rod 43 close to the spring 42 is fixedly connected to the limit plate 44. Here, a baffle is provided on the inner side of the end of the sleeve rod 41 close to the inner rod 43, which can be used to block the limit plate 44, thereby preventing the inner rod 43 from falling out of the sleeve rod 41.

[0047] The inner bottom of the connection box 101 is fixedly connected to a mounting plate, and the support member includes an electric push rod 102 fixedly connected to one side of the mounting plate. Here, the electric push rod 102 is electrically connected to the controller, and the controller can control the extension and start of the electric push rod 102. The output end of the electric push rod 102 is fixedly connected to a limiting member.

[0048] A sliding groove is provided at the bottom of the connecting box 101, and the limiting part includes a push block 103 which is slidably connected to the inside of the limiting groove. The bottom of the push block 103 is fixedly connected to an arc-shaped support plate 105, and one side of the push block 103 is fixedly connected to the output end of the electric push rod 102. The inner arc side of the arc-shaped support plate 105 is inclined from top to bottom. Here, when the ends of the two arc-shaped support plates 105 contact, the two form a closed loop and fit with the bottom end of the cup body to provide support for the bottom end of the cup body.

[0049] When the cup bottom extension platform 11 continues to press upward, the inner bottom of the positioning groove 15 can continuously push up the positioning rod 9, thereby causing the positioning rod 9 to drive the movable column 61 and the connecting seat 51 to move upward, so that the cup body fixed on the support airbag 8 moves upward, so that the cup bottom is always maintained in the pre-set insertion position range, thereby improving the accuracy of docking positioning. At the same time, when the inner bottom of the positioning groove 15 continues to push up the positioning rod 9, the limiting plate 91 can squeeze the sensing end of the pressure sensor 13. After the pressure sensor 13 senses the pressure, it can transmit an electrical signal to the controller, and the controller turns on the electric push rod 102, causing the electric push rod 102 to extend. This in turn drives the push block 103 to move, thereby driving the arc-shaped support plate 105 to move toward the cup body, so that the two arc-shaped support plates 105 fit against the bottom end of the cup body, thereby providing support for the bottom end of the cup body, preventing the bottom end of the cup body from curling, wrinkling or breaking when the cup bottom extension platform 11 is over-inserted, avoiding affecting the docking accuracy of the cup body and the cup bottom, and improving the production efficiency of paper cups. When the adjusting part 5 is forced to lift upward, the inner rod 43 can shrink toward the inside of the sleeve rod 41, thereby realizing the upward lifting of the adjusting part 5. When the adjusting part 5 loses the effect of the force, the inner rod 43 is pushed up by the elastic action of the spring 42, thereby quickly resetting the adjusting part 5.

[0050] The remaining structures are the same as those of Examples 1 and 2.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
