Description

Technical Field

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

[0002] A disposable paper cup is a disposable container mainly made of paper and used to hold beverages or other liquids. It is widely used in scenarios such as households, offices, and food service. Disposable paper cups are made of food-grade wood pulp paper and usually have a waterproof coating on the inner wall to prevent leakage. Its core features are convenience in use, low price, and compliance with hygiene standards, avoiding the risk of cross-contamination caused by repeated use.

[0003] When producing disposable paper cups currently, it is necessary to first cut the original paper into a predetermined shape, then perform film coating and printing on the cut original paper, and then perform cup rolling and bonding. After bonding, the rolled cup body is curled at the cup mouth, and then the cup body and the cup bottom are docked and sealed to complete the production of disposable paper cups. Among these processes, the cup bottom sealing process for the cup body is particularly important.

[0004] When producing and processing existing disposable paper cups, it is mostly necessary to support and fix the rolled cup body with an airbag, and then position and insert the supported cup body and the cup bottom to complete the cup bottom sealing process. However, when docking the cup body and the cup bottom, since the cup body is supported and fixed by an airbag inside, it is inevitable that the cup body will be tilted or misaligned after being fixed, which easily causes problems such as deformation or dislocation when the cup body is docked with the cup bottom, making the docking production process unstable, increasing the rejection rate, and reducing the product quality. Summary of the Invention

[0005] To overcome the deficiencies of the prior art, the present invention provides a positioning device for the production and processing of disposable paper cups. The cup body is straightened and adjusted by a straightening member so that the cup body is in a vertical state, avoiding tilting of the cup body during fixation, ensuring that the cup body and the cup bottom are perpendicular to each other when docked, and thus improving the accuracy of docking between the cup body and the cup bottom.

One side of the push block is fixedly connected to the output end of the electric push rod. The inner arc side of the arc-shaped support plate is inclined from top to bottom.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the cup body is fixed by the rapidly expanding support airbag. Then, through the operation of the adjusting member, the internal components of the adjusting member drive the two aligning members, thereby driving the two aligning members to move towards the cup body, and then quickly adjusting the position and angle of the cup body, so that the cup body is in a vertical state, avoiding the inclination of the cup body during fixation, making the cup body and the cup bottom perpendicular to each other when docking, thereby improving the accuracy of the docking between the cup body and the cup bottom, and thus improving the docking efficiency; 2. When the adjusting member drives the aligning member to move, the restricting member can be driven synchronously, so that the internal component of the restricting member extends from one side of the aligning member and cooperates with the aligning member to form an annular closed loop that fits the outer wall of the cup body on the outer wall of the cup body. Then, it cooperates with the inflated support airbag to restrict the cup body, preventing the cup body from being wrinkled or skewed due to external force during docking, further improving the accuracy of the docking between the cup body and the cup bottom and enhancing the docking efficiency. 3. During the operation of the electric turntable and the electric track, the position of the cup body can be adjusted, and the positions of the cup body and the cup bottom top extension platform can be visually positioned through a visual detector. During this period, the infrared emitter can continuously emit infrared rays. When the infrared rays emitted by the two infrared emitters are simultaneously received by the two infrared receivers, the electric turntable and the electric track can stop operating. At this time, the positioning rod is vertically corresponding to the positioning groove, 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 position positioning of the cup body and the cup bottom. 4. When the cup bottom top extension platform drives the cup bottom to insert into the cup body, during the moving process, the positioning rod inserts into the positioning groove. When the bottom end of the positioning rod touches the inner bottom of the positioning groove, the cup bottom reaches the preset insertion position, thus achieving precise positioning of the insertion position of the cup body and the cup bottom, and further improving the positioning accuracy. At the same time, when the cup bottom top extension platform is inserted excessively, the inner bottom of the positioning groove tops the positioning rod, causing the positioning rod to exert force to top the aligning member and the adjusting member, making the two lift upward, and then the cup body lifts upward, so that the cup bottom always remains within the preset insertion position range, thereby improving the accuracy of the docking positioning. Meanwhile, when the positioning rod is stressed, the pressure sensor senses the pressure, and then the protective member is activated, causing the internal component of the protective member to quickly unfold and form an external support force at the bottom end of the paper cup, preventing the bottom end of the cup body from being externally curled, wrinkled or broken when the cup bottom top extension platform is inserted excessively, further improving the accuracy of the docking and enhancing the production efficiency of the paper cup.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0029] Please refer to 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, including a workbench 1. On one side of the top of the workbench 1, an electric turntable 2 is fixedly connected. At the top of the electric turntable 2, a plurality of electric tracks 3 are fixedly connected. On the electric tracks 3, symmetrically arranged elastic telescopic members 4 are installed. At the bottom end of the elastic telescopic member 4, an adjusting member 5 is fixedly connected. On the adjusting member 5, symmetrically arranged aligning members 6 are drivingly connected. On the aligning member 6, a limiting member 7 is installed. The adjusting member 5 is drivingly connected to the limiting member 7. Here, the opposite surfaces of the two aligning members 6 are both arc-shaped and are in a downward-sloping state from top to bottom, and the degree of inclination is consistent with the production specifications of the cup body. The inner arc side of the limiting member 7 and the inner arc side of the aligning member 6 have the same structure, and the inner arc sides of the limiting member 7 and the aligning member 6 are connected to form a smooth plane, which can form a seamless fit with the outer wall of the cup body. In the middle of the bottom of the adjusting member 5, a support airbag 8 is fixedly connected. The top end of the support airbag 8 can be connected to an external air pump. The support airbag 8 is quickly inflated through the air pump, so that the support airbag 8 bulges in the cup body, and then the cup body is fixed by inflating and expanding to support the inner wall of the cup body. When separating the cup body, part of the gas inside the support airbag 8 can be pumped out through the external air pump, so that a gap is formed between the support airbag 8 and the inner wall of the cup body, and the cup body falls under the action of gravity, and the cup body can be separated. Moreover, after the support airbag 8 expands, it is conical and matches the structure of the inner wall of the cup body. On one side of the adjusting member 5, a vision detector 14 is installed. Through the vision detector 14, the positions of the cup bottom top extension platform 11 and the cup body on the support airbag 8 can be detected, and then the cup body is moved to directly above the cup bottom top extension platform 11 and is vertically corresponding to it in cooperation with the electric turntable 2 and the electric tracks 3. At the bottom of the aligning member 6, a protective member 10 is fixedly connected. On the protective member 10, a positioning rod 9 is installed. On one side of the top of the protective member 10, a pressure sensor 13 is fixedly connected, and on one side of the bottom of the protective member 10, an infrared receiver 12 is fixedly connected. One end of the positioning rod 9 contacts the sensing end of the pressure sensor 13. Here, a controller is provided at the top of the adjusting member 5. The pressure sensor 13 can detect the pressure received by the positioning rod 9 and send a signal to the controller. Then, the protective member 10 is started through the controller. On one side of the top of the workbench 1, a cup bottom top extension platform 11 is installed. On both sides of the cup bottom top extension platform 11, positioning grooves 15 are provided, which can preset the position where the cup bottom is inserted into the cup body. When the bottom end of the positioning rod 9 reaches the inner bottom of the positioning groove 15, the cup bottom can reach the set position. On both sides of the top of the cup bottom top extension platform 11, infrared transmitters 16 are installed. Infrared rays are released through the infrared transmitters 16. When the infrared receiver 12 is vertically corresponding to the infrared transmitter 16, the infrared receiver 12 receives the infrared rays. At this time, the cup body and the cup bottom top extension platform 11 are in a vertically corresponding state, and the electric turntable 2 and the electric tracks 3 stop driving, thereby realizing the precise alignment of the cup body and the cup bottom on the cup bottom top extension platform 11; The cup body is fixed by the inflation of the supporting airbag 8. The adjusting member 5 drives the two aligning members 6, so that the two aligning members 6 move towards the cup body direction, and the angle and position of the cup body are adjusted. During the movement of the aligning member 6, the limiting member 7 is extended under the action of the adjusting member 5 and fits against the side wall of the cup body. After that, the electric turntable 2 drives the electric track 3 and the adjusting member 5 to rotate, and drives the infrared receiver 12 to move. When the infrared receiver 12 receives the infrared rays emitted by the infrared emitter 16, the electric turntable 2 stops rotating. At this time, the cup body and the cup bottom jacking table 11 are on the same axis, and the positioning of the cup body and the cup bottom can be completed.

[0030] The adjusting member 5 includes a connecting seat 51 fixedly connected to the bottom end of the elastic telescopic member 4. Inner grooves 54 are formed on both sides of the connecting seat 51, and a bidirectional threaded rod 53 is rotatably connected inside 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 inside the inner groove 54.

[0031] The aligning member 6 includes a driving block 63 slidably connected inside the inner groove 54. Here, the outer wall of the driving block 63 is smooth, which can reduce the friction between the driving block 63 and the inner groove 54 and improve the smoothness during movement. A moving column 61 is fixedly connected to the bottom of the driving block 63, and the driving block 63 is threadedly connected to the bidirectional threaded rod 53. A plurality of arc-shaped deflectors 62 are fixedly connected to one side of the moving column 61. The inner arc side of the arc-shaped deflectors 62 is inclined from top to bottom and fits with the outer wall of the cup body. Guide grooves 64 are formed at both the upper and lower ends of the arc-shaped deflectors 62. 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 by 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 direction of 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 detected 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 infrared transmitter 16 can continuously release infrared light. 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 realize the precise positioning of the cup body and the cup bottom. After that, 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 insertion position of the cup body and the cup bottom can be realized.

[0032] 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 shift 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 maintains a vertically centered state under the connecting seat 51, thereby avoiding the cup body from tilting when fixed, so that when the cup body and the cup bottom are docked, the two remain in a vertical state, thereby improving the accuracy of the docking between the cup body and the cup bottom, thereby improving the docking efficiency. Example 2

[0033] 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 arc-shaped tooth plates 71 slidably installed between multiple arc-shaped shifting plates 62, and the upper and lower ends of the arc-shaped tooth plates 71 are fixedly connected with guide plates 72. Here, the inner arc side structure of the arc-shaped tooth plate 71 is consistent with the arc-shaped shifting 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 with a driving member, which is transmission-connected to the arc-shaped tooth plate 71.

[0034] The driving member includes a rotating rod 73 rotatably connected inside the moving column 61. A plurality of driving gears 74 are fixedly connected to the rotating rod 73. The driving gears 74 are meshed and connected with the arc-shaped tooth plates 71. The top of the moving column 61 is fixedly connected with a gear commutator 75. The top end of the rotating rod 73 is fixedly connected with the gear commutator 75. A transmission gear 76 is fixedly connected to the side of the gear commutator 75 away from the rotating rod 73. The transmission gear 76 is meshed and connected with the rack 55.

[0035] When the moving column 61 moves, it can drive the limiting member 7 to move synchronously, so that the rotating rod 73, the gear commutator 75 and the transmission gear 76 move synchronously with the moving column 61. During this period, when the transmission gear 76 moves, it can be driven by the rack 55, so that the transmission gear 76 rotates. The rotating transmission gear 76 can drive the rotating rod 73 to rotate by means of the gear commutator 75, and then drive a plurality of driving gears 74 to rotate, so as to drive a plurality of arc-shaped tooth plates 71, so that the arc-shaped tooth plates 71 extend out from between the two arc-shaped deflectors 62. When the moving column 61 fits with the cup body, at this time, the arc-shaped tooth plates 71 are stretched out. Through the plurality of arc-shaped tooth plates 71, a supporting force can be formed on the outer wall of the cup body, and cooperate with the plurality of arc-shaped deflectors 62 to form a circular closed loop on the outer side of the cup body, and then cooperate with the inflated supporting airbag 8 to limit the cup body, preventing the cup body from being wrinkled and skewed due to external force during docking, and further improving the accuracy of the docking between the cup body and the cup bottom. When the arc-shaped tooth plates 71 extend, they can drive the guiding plate 72 to slide inside the guiding groove 64. Through the guiding plate 72, the movement of the arc-shaped tooth plates 71 can be guided and limited, preventing the arc-shaped tooth plates 71 from shifting during movement.

[0036] The remaining structures are the same as those in Embodiment 1. Embodiment 3

[0037] Please refer to Figure 6 、 Figure 7 、 Figure 8 and Figure 10 This is the third embodiment of the present invention. The difference between this embodiment and the first and second embodiments is that the protective member 10 includes a connection box 101 fixedly connected to the bottom of the moving column 61. An installation groove 104 is provided at the inner bottom of the connection box 101, and a support member is installed on one side inside the connection box 101.

[0038] The positioning rod 9 is slidably installed in the installation groove 104, and a limiting plate 91 is fixedly connected to one end of the positioning rod 9 close to the connection box 101. The limiting plate 91 contacts the inner port of the installation groove 104. The pressure sensor 13 is fixedly connected to the top of the connection box 101, and the sensing end of the pressure sensor 13 is in close 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, which can avoid the phenomenon that the protective member 10 is started due to a slight pressure generated on the pressure sensor 13 when the positioning rod 9 is inserted into the positioning groove 15.

[0039] The elastic telescopic member 4 includes a sleeve rod 41 fixedly connected to the electric track 3. A spring 42 is fixedly connected inside the sleeve rod 41. One end of the spring 42 far from the sleeve rod 41 is fixedly connected to an inner rod 43. A limiting plate 44 is fixedly connected to one end of the inner rod 43 close to the spring 42. Here, a retaining piece is provided on the inner side of one end of the sleeve rod 41 close to the inner rod 43, which can be used to block the limiting plate 44, thereby preventing the inner rod 43 from slipping out of the sleeve rod 41.

[0040] The inner bottom of the connection box 101 is fixedly connected with a mounting plate. 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 telescopic start and stop of the electric push rod 102 can be controlled through the controller. The output end of the electric push rod 102 is fixedly connected with a limiting member.

[0041] A chute is opened at the bottom of the connection box 101. The limiting member includes a push block 103 slidably connected inside the limiting groove. The bottom of the push block 103 is fixedly connected with 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, they 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.

[0042] When the bottom cup jacking platform 11 continuously jacks upwards, the inner bottom of the positioning groove 15 can continuously jack up the positioning rod 9, thereby causing the positioning rod 9 to drive the moving column 61 and the connecting seat 51 to move upwards, making the cup body fixed on the supporting airbag 8 move upwards, so that the bottom of the cup always remains within the preset insertion position range, thereby improving the accuracy of docking and positioning. At the same time, when the inner bottom of the positioning groove 15 continuously jacks 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 electric push rod 102 is turned on through the controller, causing the electric push rod 102 to extend, thereby driving the push block 103 to move, and then driving the arc-shaped support plate 105 to move towards the cup body direction, so that the two arc-shaped support plates 105 fit the bottom end of the cup body, thereby providing support for the bottom end of the cup body to prevent the phenomenon of outward curling, wrinkling or cracking at the bottom end of the cup when the bottom cup jacking platform 11 is inserted excessively, avoiding affecting the docking accuracy of the cup body and the bottom of the cup, and improving the production efficiency of the paper cup. When the adjusting member 5 is forced to lift upwards, the inner rod 43 can contract towards the inside of the sleeve rod 41, thereby realizing the upward lift of the adjusting member 5. When the adjusting member 5 loses the acting force, under the elastic action of the spring 42, the inner rod 43 is pushed upwards, thereby quickly resetting the adjusting member 5.

[0043] The remaining structures are the same as those of Embodiments 1 and 2.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
