DETAILED DESCRIPTION

[0034] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0035] See also Figures 1-6 The present embodiment provides a discharging device of a rewinding machine, comprising a frame plate 1, a sleeve 2, a telescopic assembly, a locking assembly 4 and a connecting plate 5. The frame plate 1 is arranged on the ground, the telescopic assembly is arranged on the frame plate 1, the output end of the telescopic assembly is connected to the connecting plate 5, the connecting plate 5 is coaxially provided with a connecting slot, the connecting plate 5 is coaxially sleeved on one end of the sleeve 2 through the connecting slot, the connecting plate 5 is provided with a locking slot, the locking slot and the connecting slot are communicated with each other, the locking assembly 4 is arranged in the locking slot, and the locking assembly 4 is arranged in the locking slot. One end of the cam is connected to the connecting disk 5, and the other end of the cam can lock or release the abutting relationship with the sleeve 2; by providing a locking component 4 and a telescopic component, the telescopic component adjusts the connecting disk 5 to the position of the sleeve 2 by controlling the movement of the connecting disk 5, and the function of the locking component 4 is to lock the abutting relationship with the sleeve 2, thereby locking the connecting disk 5 in the current position of the sleeve 2; it is worth noting that the function of the connecting disk 5 is to limit the position of the paper during rewinding so that the paper will not move around. Due to such a setting, the surface of the sleeve 2 is ensured to be smooth and cylindrical, and the connecting disk 5 can be moved by the telescopic component, so that the connecting disk 5 can limit the paper of different widths, solving the problem that the shaft sleeve of the existing rewinding machine limits the position of the connecting sleeve by providing a slider. However, due to the slider provided on the shaft sleeve, the existing rewinding machine can only rewind paper of a single width, and cannot arbitrarily adjust the width between the two connecting sleeves according to the width of the paper. When it is necessary to rewind paper of a larger width, the matching shaft sleeve needs to be replaced; therefore, there is a problem of delaying the speed and efficiency of paper rewinding in the existing matching structure between the shaft sleeve and the connecting sleeve.

[0036] Specifically, the telescopic assembly of this scheme includes several telescopic rods 3, which are arranged at equal angles around the central axis of the sleeve 2. One end of the telescopic rod 3 is connected to the frame plate 1, and the output end of the telescopic rod 3 is connected to the connecting disk 5. The axial direction of the telescopic rod 3 is parallel to the central axis of the connecting disk 5. The output end of the telescopic rod 3 is extended and retracted, thereby realizing the movement of the connecting disk 5 at one end of the sleeve 2.

[0037] It should be noted that the present invention further provides a rotating motor, which is provided on the frame plate 1, and the output end of the rotating motor is coaxially connected to one end of the sleeve 2 to control the rotation of the sleeve 2; since the connecting disk 5 is now connected to the sleeve 2 through the locking assembly 4, the connecting disk 5 will rotate along with the rotation of the sleeve 2; however, the telescopic rod 3 of the present invention will not rotate along with the rotation of the connecting disk 5, in order to avoid interference between the connecting disk 5 and the telescopic rod 3 during the rotation of the connecting disk 5; the connecting disk 5 of the present invention includes a plurality of rings 501 and connecting round blocks 50 2. The connecting block 502 is coaxially arranged at one end of the sleeve 2, and the connecting block 502 is located between the sleeve 2 and the frame plate 1. A circular groove is coaxially opened at one end of the connecting block 502 close to the frame plate 1, and a plurality of circular rings 501 are slidably arranged in the circular groove. The plurality of circular rings 501 are matched with a plurality of telescopic rods 3 in a one-to-one manner. The output end of any telescopic rod 3 is connected to the corresponding circular ring 501. Through such an arrangement, the telescopic rod 3 can drive the connecting block 502 to move along one end of the sleeve 2, while the rotation of the connecting block 502 and the position of the telescopic rod 3 do not interfere with each other.

[0038] Specifically, the locking assembly 4 of this solution includes a plurality of locking units, a plurality of locking slots are provided, and a plurality of locking slots are provided in the connecting circular block 502 at equal angles around the central axis of the connecting circular block 502. The plurality of locking slots are matched with the plurality of locking units one by one, and any locking unit is provided in the corresponding locking slot; the locking unit includes a locking spring 401 and a locking slider 402, the locking slider 402 is slidably sealed in the locking slot, and the locking spring 401 is provided in the locking slot. The two ends of the locking spring 401 are respectively connected to the connecting round block 502 and the locking slider 402; by providing the locking spring 401 and the locking slider 402, the locking slider 402 moves in the corresponding locking slot, so that the locking slider 402 is fitted with the sleeve 2, thereby realizing that the connecting round block 502 is locked at the current position of the sleeve 2, and the function of the locking spring 401 is to reset the locking slider 402, so that the locking slider 402 releases its fitting relationship with the sleeve 2.

[0039] Furthermore, in order to realize the sliding of the locking slider 402, the locking assembly 4 of this solution also includes an air pump 403, and the connecting round block 502 is further provided with a plurality of communicating slots. There is a communicating space between two adjacent locking slots, and the plurality of communicating spaces are matched one-to-one with the plurality of communicating slots. Any communicating slot is arranged in the corresponding communicating space, and the two ends of the communicating slot are respectively communicated with the two adjacent communicating slots. The air pump 403 is arranged on the frame plate 1, and the air pump 403 is communicated with any locking slot; An air pump 403 is provided, and the locking slots are interconnected. When the air pump 403 inputs air pressure into any locking slot, it can ensure that the remaining locking sliders 402 are subjected to the same air pressure force. The locking slider 402 will move toward the direction close to the sleeve 2 due to the air pressure force until the locking slider 402 and the sleeve 2 are fitted together. In addition, it is worth noting that when the air pressure in the locking slot is reduced, the locking spring 401 will pull the locking slider 402 to reset.

[0040] Similarly, since the air pump 403 of the present invention is arranged on the frame plate 1 and will not rotate, while the connecting round block 502 will rotate, in order to ensure that the connection between the air pump 403 and the connecting round block 502 can always maintain normal operation, the locking component 4 of the present invention also includes a rotating outer ring 404, a rotating inner ring 405, an internal hollow connecting pipe 406 and a one-way valve 407, the rotating inner ring 405 is coaxially provided with a rotating slot, the rotating inner ring 405 is coaxially arranged on the end of the connecting round block 502 close to the telescopic rod 3, the output end of the telescopic rod 3 is connected to the ring 501 by passing through the rotating slot, the rotating outer ring 404 is rotatably coaxially sleeved on the side wall of the rotating inner ring 405, the inner side wall of the rotating outer ring 404 is provided with an annular ventilation slot, the rotating outer ring 404 and the rotating inner ring 405 cooperate to form a ventilation space, the rotating inner ring 405 is provided with an inner ring groove, the inner ring groove and the ventilation space are connected to each other, and the connecting pipe 406 is provided with a one-way valve 407. It is arranged horizontally, and the two ends of the connecting pipe 406 are respectively connected to the rotating inner ring 405 and the connecting round block 502. The inner ring groove is connected to any connecting slot hole through the connecting pipe 406. The rotating outer ring 404 is provided with a fixed slot hole, which is connected to the ventilation space. The output end of the air pump 403 is connected to the fixed slot hole, and a one-way valve 407 is arranged at the connection between the air pump 403 and the fixed slot hole; by providing the rotating outer ring 404 and the rotating inner ring 405, the air pump 403 starts working and transports the air pressure to the ventilation space through the fixed slot hole. The air pressure in the ventilation space moves to the connecting pipe 406 through the inner ring groove, and then reaches the connecting slot hole through the connecting pipe 406, thereby increasing the air pressure in each locking slot hole to realize the movement of the locking slider 402. The function of the one-way valve 407 is that after the air pump 403 stops working, the gas in the locking slot hole will not leak from the position of the air pump 403.

[0041] In addition, this solution also includes a receiving component 6 and an auxiliary frame 7. The frame plate 1 can be slidably set on the ground along the axial direction of the sleeve 2. The auxiliary frame 7 can be slidably set at the other end of the sleeve 2 along the axial direction of the sleeve 2. The telescopic component, the locking component 4 and the connecting plate 5 are each provided in two groups. The other group of telescopic components, the locking component 4 and the connecting plate 5 are all provided on the auxiliary frame 7, and they cooperate with each other to be connected to the other end of the sleeve 2; the receiving component 6 includes two telescopic cylinders 601 and an internal hollow receiving plate 602. The receiving plate 602 is centrally arranged at the bottom of the sleeve 2. The two telescopic cylinders 601 are vertically arranged at both ends of the receiving plate 602. The telescopic cylinders 601 are vertically arranged at both ends of the receiving plate 602. The two ends of 01 are respectively connected to the ground and one end of the receiving tray 602; the cross-sectional width of the receiving tray 602 decreases from top to bottom, and the bottom width of the receiving tray 602 is equal to the outer diameter of the sleeve 2; by providing a receiving component 6, when the sleeve 2 completes the winding of the paper, the telescopic cylinder 601 starts to work, driving the receiving tray 602 to start rising until the receiving tray 602 is in contact with the paper, and then the connecting disk 5 releases its locking relationship with the sleeve 2, and the frame plate 1 and the auxiliary frame 7 start to move, so that the connecting disk 5 starts to slide and slides out of the sleeve 2, and the sleeve 2 will be caught by the receiving tray 602, realizing the automatic unloading of the sleeve 2 that has completed the paper rewinding.

[0042] According to the above embodiment, in order to ensure that the connecting disk 5 can release its locking cooperation with the sleeve 2 after the sleeve 2 completes the rewinding of the paper, the rotating outer ring 404 of this solution is provided with a sealing slot, and the sealing slot is connected to the ventilation space. It also includes two sets of air release components 8, and the air release component 8 includes a sealing block 801. The two sealing blocks 801 are matched with the two rotating outer rings 404 one by one. Any sealing block 801 is used to lock or release its sealing cooperation relationship with the corresponding sealing slot; it is worth noting that the sealing block 801 is semi-prismatic, and its cross-sectional area decreases from top to bottom, and the shape of the sealing slot is adapted to the sealing block 801. When the side wall surface of the sealing block 801 is sealed in contact with the sealing slot, the ventilation space is in a sealed state; when the side wall surface of the sealing block 801 is no longer sealed in contact with the sealing slot, the ventilation space is in a connected state with the external environment, and the air pressure in the locking slot will move to the external environment through the ventilation space, thereby achieving air release of the locking slot.

[0043] In addition, in order to realize the sliding of the sealing block 801, the two sets of deflation components 8 of this scheme are matched with the frame plate 1 and the auxiliary frame 7 in a one-to-one manner, and any deflation component 8 is set on the frame plate 1 or the auxiliary frame 7; taking the frame plate 1 as an example here, the deflation component 8 also includes a driving block 802, a transverse rod 803, a vertical rod 804 and a sealing spring 805, the transverse rod 803 can be set on the frame plate 1 for transverse sliding, and the vertical rod 804 can be set on the frame plate 1 for vertical sliding, and the two ends of the sealing spring 805 are respectively connected to the frame plate 1 and the vertical rod 804; the top end of the vertical rod 804 is connected to the sealing block 801, and the bottom end of the vertical rod 804 is in contact with the transverse rod 803; the transverse rod 803 and The ends of the vertical rods 804 that are in contact with each other are tilted, and as viewed along the axial direction of the horizontal rod 803 toward the direction close to the vertical rod 804, the vertical heights of the ends of the horizontal rods 803 and the vertical rods 804 that are in contact with each other gradually decrease. It is worth noting that the ends of the horizontal rods 803 and the vertical rods 804 that are in contact with each other are tilted, and both ends of the tilted end are planes, but the height positions of the planes are different. When the vertical rod 804 is located at a plane with a low height position, the sealing block 801 and the sealing slot are in a sealing relationship. When the horizontal rod 803 starts to slide, the vertical rod 804 will move to a plane with a high height position through the tilted end, and the sealing block 801 and the sealing slot will release the sealing relationship with each other.

[0044] Furthermore, in order to realize the sliding of the transverse rod 803, the two driving blocks 802 are matched with the two telescopic cylinders 601 in a one-to-one manner. Any driving block 802 is set on the output end of the corresponding telescopic cylinder 601, and the bottom of the end of the transverse rod 803 away from the vertical rod 804 is tilted. Looking along the axis direction of the transverse rod 803 toward the direction close to the vertical rod 804, the vertical height of the bottom of the end of the transverse rod 803 away from the vertical rod 804 gradually increases. The driving block 802 can lock or release its abutment with the end of the transverse rod 803 away from the vertical rod 804. Yes, when the sleeve 2 completes the winding of the paper, the telescopic cylinder 601 starts to work, controlling the receiving tray 602 to move toward the top until the receiving tray 602 is in contact with the paper; during this period, the driving block 802 is in contact with the bottom of the end of the transverse rod 803 away from the vertical rod 804, and due to the inclination of the bottom of the end of the transverse rod 803 away from the vertical rod 804, the driving block 802 is in contact with the inclined end of the bottom of the end of the transverse rod 803 away from the vertical rod 804, and the transverse rod 803 is driven to move toward the direction close to the vertical rod 804, thereby realizing the transverse movement of the transverse rod 803.

[0045] In addition, in order to ensure the reset of the transverse rod 803, that is, to ensure that the sealing block 801 can re-establish the sealing cooperation between the sealing block 801 and the sealing slot after releasing the sealing cooperation between the sealing block 801 and the sealing slot, the degassing assembly 8 of this solution further includes a reset block 806, which is set on the ground and is located at one end of the transverse rod 803 close to the vertical rod 804. The transverse rod 803 can lock or release the abutting cooperation relationship between the reset block 806; according to the above embodiment, when the rack plate 1 starts to move, so that the connecting plate 5 opens, After the horizontal rod 803 starts to slide and slides out of the sleeve 2, the horizontal rod 803 will be in contact with the reset block 806. Since the reset block 806 cannot move, after the horizontal rod 803 is in contact with the reset block 806, the horizontal rod 803 will slide horizontally in the direction away from the vertical rod 804, so that the vertical rod 804 moves from the plane where the horizontal rod 803 is at a high height to the plane where the horizontal rod 803 is at a low height, thereby re-realizing the sealing cooperation relationship between the sealing block 801 connected to the vertical rod 804 and the sealing slot.

[0046] It is worth noting that in order to ensure the automation of the device, after the staff takes out the sleeve 2 that has completed the paper rewinding, they only need to place the new sleeve 2 on the receiving tray 602; at this time, the telescopic cylinder 601 starts to work, driving the receiving tray 602 to move toward the top until the central axis of the sleeve 2 coincides with the central axis of the connecting disk 5, and then the frame plate 1 and the auxiliary frame 7 start to move, and after controlling the connecting disk 5 to slide onto the sleeve 2, the driving cylinder controls the receiving tray 602 to reset; it should be noted that, taking the frame plate 1 as an example, when the frame plate 1 starts to move and drives After the connecting plate 5 slides onto the sleeve 2 again, the driving block 802 is located at the top of the transverse rod 803. In order to ensure that the driving block 802 and the transverse rod 803 do not interfere with the normal operation of the telescopic cylinder 601 when the telescopic cylinder 601 controls the receiving plate 602 to reset, the transverse rod 803 of this solution includes a transverse sliding block 8031, a transverse hinge block 8032 and a hinge spring 8033. The transverse sliding block 8031 ​​can be laterally slidably arranged on the frame plate 1. The transverse sliding block 8031 ​​is tilted at one end close to the vertical rod 804. The transverse hinge block 8032 is hingedly arranged at the transverse The sliding block 8031 ​​is away from one end of the vertical rod 804, and the two ends of the hinge spring 8033 are respectively connected to the transverse hinge block 8032 and the transverse sliding block 8031. The driving block 802 can lock or release its abutting cooperation relationship with the transverse hinge block 8032. By providing the transverse hinge block 8032, when the driving block 802 moves from the top position of the transverse hinge block 8032 to the bottom position of the transverse hinge block 8032, the transverse hinge block 8032 is hinged with the transverse sliding block 8031 ​​to prevent the telescopic cylinder 601 from resetting when the control receiving plate 602 is in operation. When the horizontal hinge block 8032 is in the vertical position, the driving block 802 and the horizontal rod 803 interfere with the normal operation of the telescopic cylinder 601; when the driving block 802 moves from the bottom position of the horizontal hinge block 8032 to the top position of the horizontal hinge block 8032, due to the inclined setting of the bottom of the horizontal hinge block 8032 and the action of the hinge spring 8033, the horizontal hinge block 8032 can only be hinged from top to bottom under normal circumstances, and cannot be hinged from bottom to top. Therefore, at this time, the horizontal hinge block 8032 will drive the horizontal sliding block 8031 ​​to slide horizontally in the direction close to the vertical rod 804.
