DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0027] Referring to the drawingsFigures 1-12 As shown, in the present embodiment, a kind of life paper overturns and positions the shaft paper discharging device, for adapting existing rewinder, slitting machine and shaft extractor, by single installation to realize the functions such as paper receiving, shaft positioning, paper discharging to rewound paper roll A, reach the effect of one machine multiple use.Specifically including the overturning paper discharging assembly between the preset rewinding discharge channel 10 and discharge channel 20, wherein the overturning paper discharging assembly includes the support tipping bucket 1 for supporting paper roll A, the tipping bucket driving unit 2 for driving the support tipping bucket 1 to make fixed shaft overturning action, and positioning device 3.

[0028] In the present embodiment, the support tipping bucket 1 longitudinal section is "V-shaped" structure.The overturning paper discharging assembly further includes the fixed support 12 for the support tipping bucket 1 to be hinged, wherein the support tipping bucket 1 makes fixed shaft overturning action around the hinge point between it and the fixed support 12 (i.e.: the bottom of support tipping bucket 1 is passed through the horizontal hole of the fixed support 12 preset to realize the relative overturning action around the horizontal axis of the two).The tipping bucket driving unit 2 preferably adopts oil pressure type, pneumatic type telescopic piece, and the telescopic end thereof is pivoted with the bottom of support tipping bucket 1, and the body thereof is pivoted on the preset base, so that the corresponding overturning action of support tipping bucket 1 is driven by the telescopic action of tipping bucket driving unit 2.

[0029] Therefore, under the driving of tipping bucket driving unit 2, the support tipping bucket 1 is correspondingly circulated and switched between the preset paper receiving state, shaft extracting state and paper feeding state.

[0030] Specifically, when the support tipping bucket 1 is in the paper receiving state, the bucket mouth of support tipping bucket 1 is aligned with the rewinding discharge channel 10 to receive paper roll A, i.e.: the paper roll A with winding shaft is sent out along the rewinding discharge channel 10 after completing the rewinding operation, so as to roll down to the support tipping bucket 1 which is pre-overturned in place through the bucket mouth, realizing the receiving action of paper roll A.

[0031] Specifically, when the support tipping bucket 1 is in the shaft extracting state, the bucket mouth of support tipping bucket 1 is upward to fixedly hold paper roll A, i.e.: after paper roll A rolls down in support tipping bucket 1, the support tipping bucket 1 is switched from the paper receiving state to the shaft extracting state by means of tipping bucket driving unit 2, so as to hold paper roll A in support tipping bucket 1, so that the winding shaft of paper roll A is axially extracted by the shaft extractor (the shaft extraction operation can refer to the related technical solutions described in "CN220334287U, a paper roll A extractor for life paper", and the skilled in the art can adopt the derived shaft extraction mode, which will not be expanded here).

[0032] Further, in order to facilitate the accuracy of the shaft pulling operation, when the support hopper 1 is in the shaft pulling state, the angle center line a of the support hopper 1 is vertical, so that the center of the paper roll A rolled in the support hopper 1 is just on the angle center line a of the support hopper 1, regardless of the diameter of the paper roll A, so that the winding shaft is just on the vertical plane, and the shaft puller only needs to perform a lifting action to adapt to paper rolls A of different diameters.

[0033] Specifically, when the support hopper 1 is in the paper feeding state, the hopper opening of the support hopper 1 is aligned with the discharge channel 20 to dump the paper roll A, that is, after the shaft pulling operation is completed, the support hopper 1 is driven by the hopper driving unit 2 to flip and switch from the shaft pulling state to the paper feeding state, so that the hopper opening of the support hopper 1 is aligned with the discharge channel 20, so that the paper roll A is no longer limited to be rolled through the hopper opening to the discharge channel 20; and after the paper roll A rolls away from the support hopper 1, the support hopper 1 can be driven by the hopper driving unit 2 to flip and switch from the paper feeding state to the paper receiving state to wait for the next paper roll A.

[0034] In summary, by cyclically flipping and switching the support hopper 1 between the paper receiving state, the shaft pulling state and the paper feeding state, continuous paper receiving, positioning and paper feeding operations on the paper roll A can be achieved.

[0035] In the present embodiment, the positioning device 3 stops and positions the support hopper 1 in the shaft pulling state, further ensuring that the angle center line a of the support hopper 1 is vertical. Specifically, at least one end surface of the support hopper 1 is provided with a positioning block 11 for positioning and stop cooperation with the positioning device 3, and each set of positioning blocks 11 synchronously flips with the support hopper 1. One positioning block 11 corresponds to one positioning device 3, in order to facilitate explanation, the following defines that both end surfaces of the support hopper 1 are provided with one positioning block 11, and correspondingly, two sets of positioning devices 3 are provided, which are arranged near the two end portions of the support hopper 1, and those skilled in the art can also use a derived way of single positioning block 11 cooperating with a single set of positioning devices 3, which is not limited specifically here.

[0036] In the present embodiment, the positioning device 3 includes a limiting block 31 for stop cooperation with the positioning block 11, and a positioning driving unit 33 for driving the limiting block 31 to move directionally, the limiting block 31 directionally moves into or out of the flipping path b of the positioning block 11 between the shaft pulling state and the paper feeding state, that is, when the limiting block 31 moves into the flipping path b of the positioning block 11, the limiting block 31 can stop and position the positioning block 11, so that the support hopper 1 is more accurately stopped at the rated position when flipped and switched to the shaft pulling state, to ensure that the angle center line a of the support hopper 1 is vertical. Conversely, when the limiting block 31 moves out of the flipping path b of the positioning block 11, the limiting block 31 no longer stops and positions the positioning block 11, so that the support hopper 1 can be flipped and switched from the shaft pulling state to the paper feeding state.

[0037] For the purpose of facilitating the understanding of the positioning device 3 described above, further explanation and description will be made in connection with two embodiments.

[0038] Embodiment one: the positioning device 3 further comprises a turnover positioning seat 32 (the turnover positioning seat 32 is pre-pivoted on a preset base) for installing the limiting stopper 31, and the positioning driving unit 33 here is preferably an oil pressure type or air pressure type telescopic piece, the telescopic end of which is pivoted with the turnover positioning seat 32 and the body of which is pivoted on the preset base, whereby the telescopic action of the positioning driving unit 33 is utilized to drive the turnover positioning seat 32 to make a top shaft turnover action, and then the limiting stopper 31 synchronously makes a turnover action, so as to correspondingly make the limiting stopper 31 turn into or out of the turnover path b of the positioning block 11. Secondly, in order to make the limiting stopper 31 adapt to the support tipping bucket 1 at different height positions, the limiting stopper 31 of the present embodiment one is a height-adjustable limiting screw relative to the turnover positioning seat 32, which is screwed on the turnover positioning seat 32, and the height position of the limiting screw relative to the turnover positioning seat 32 is correspondingly changed by screwing adjustment, so as to solve the production and assembly conditions such as tolerances existing in the actual mechanical manufacturing and installation process, and make the limiting stopper 31 be able to be adjusted to the appropriate position to position the support tipping bucket 1, and ensure that the included angle center line a of the support tipping bucket 1 keeps the vertical direction.

[0039] In the embodiment two, the positioning device 3 further comprises a sliding guide seat 35 for sliding connection of the limiting block 31, and a sliding base 36, the positioning driving unit 33 acts on the limiting block 31 to drive the limiting block 31 to translate into or out of the overturning path b of the positioning block 11 relative to the sliding guide seat 35. Specifically, the telescopic end of the positioning driving unit 33 is connected with the limiting block 31 through a preset connecting plate, and the positioning driving unit 33 is fixed on the sliding guide seat 35. Thus, the limiting block 31 is driven to move horizontally along the sliding guide seat 35 through the telescopic action of the positioning driving unit 33 via the connecting plate, so as to realize the translation of the limiting block 31 into or out of the overturning path b of the positioning block 11. Secondly, the sliding base 36 is formed with a vertical guide hole for sliding embedding of the sliding guide seat 35, wherein the sliding base 36 is provided with an adjusting unit 34 at the upper and lower positions of the outer edge of the vertical guide hole, which is in top contact with the sliding guide seat 35. The adjusting unit 34 here is a screw member screwed on the sliding base 36. By respectively screwing two groups of adjusting units 34 at the upper and lower positions of the outer edge of the vertical guide hole, the sliding guide seat 35 is correspondingly pushed to move up and down along the vertical guide hole. Specifically, when the sliding guide seat 35 needs to move upwards, the adjusting units 34 at the upper and lower positions are screwed upwards so that the adjusting unit 34 at the lower position pushes the sliding guide seat 35 to rise. Conversely, when the sliding guide seat 35 needs to move downwards, the adjusting units 34 at the upper and lower positions are screwed downwards so that the adjusting unit 34 at the upper position pushes the sliding guide seat 35 to lower. Thus, the height position of the sliding guide seat 35 and the limiting block 31 can be adjusted to adapt to the support tumbler 1 at different height positions, and the tolerance and other production and assembly conditions in the actual mechanical manufacturing and installation process can also be solved, so that the limiting block 31 can be adjusted to the appropriate position to position the support tumbler 1, and ensure that the center line a of the support tumbler 1 remains in the vertical direction.

[0040] In summary, the positioning device 3 of the above-mentioned embodiments one and two can realize the stop positioning of the support tumbler 1 in the shaft pulling state, and can avoid interference with the normal overturning action when the support tumbler 1 needs to be switched from the shaft pulling state to the paper feeding state.

[0041] In summary, the above-mentioned shaft pulling and paper discharging device has the following characteristics:

[0042] 1. Automatic adaptability: thanks to the precise stop positioning function, the support tumbler can automatically adapt to paper rolls A of different diameters without manual adjustment, improving the convenience and efficiency of operation.

[0043] 2. Precise positioning: the positioning device ensures that the center line of the support tumbler is vertical when the shaft is pulled out, ensuring the accurate position of the paper roll A and the accuracy of subsequent processing.

[0044] 3. Continuous operation capability: The support tumbler can be switched between the paper receiving, shaft pulling, and paper feeding states, realizing continuous paper roll A receiving, positioning, and feeding operations, and improving production efficiency.

[0045] 4. Stability: The stop positioning of the support tumbler in the shaft pulling state ensures its stability and reliability, reducing the risk of paper roll A damage caused by unstable tumbler.

[0046] 5. Flexibility: The design of the positioning device allows the support tumbler to be adjusted at different height positions, adapting to paper rolls A of different sizes, increasing the flexibility and application range of the equipment.

[0047] 6. Simplified operation: The automatic turnover switching mechanism simplifies the operation process, reduces manual intervention, and reduces operation complexity and labor intensity.

[0048] 7. Structural optimization: The design considers two implementation modes of the positioning device, providing structural optimization options to meet different production needs and space limitations.

[0049] 8. Easy maintenance: The design of the positioning device makes maintenance and adjustment easy, facilitating daily maintenance work and prolonging the service life of the equipment.

[0050] The above-described embodiments are only preferred embodiments of the present utility model, and do not make any form of limitation on the present utility model. Any skilled person in the art, without departing from the technical solution range of the present utility model, can make more possible changes and modifications to the technical solution of the present utility model by using the disclosed technical content, or modify it, which are all equivalent embodiments of the present utility model.
