[0006] An automatic paper changing system of an automatic paper splicer comprises an equipment body, a mobile base, a paper storage platform, an electric push rod, a support assembly and a control assembly, wherein the mobile base is arranged below a paper roll; the paper storage platform is arranged on one side of the equipment body, and a new paper roll is placed on the top of the paper storage platform; one end of the electric push rod is fixedly connected to the paper storage platform, and the other end is fixedly connected to the mobile base; the support assembly is arranged on the mobile base for supporting the paper roll; the control assembly is arranged on the mobile base for controlling the extension or contraction of the electric push rod.

[0007] By adopting the above technical solution, when the paper roll is used up, the control component is operated to drive the electric push rod to retract, and the mobile base is pulled toward the paper storage table, so that the mobile base moves to the side of the paper storage table close to the equipment body. At this time, the new paper roll on the paper storage table is rolled onto the support component, and then the control component is operated again to drive the electric push rod to extend, and the mobile base is pushed to the equipment body to install the new paper roll. There is no need for workers to carry the paper rolls, which reduces the physical exertion of workers and minimizes damage to the paper during the transportation process.

[0009] By adopting the above technical solution, when a new paper roll is placed on the support frame, the support spring is compressed under the gravity of the new paper roll. As the paper splicer continues to work, the diameter of the new paper roll gradually decreases, and the support frame moves upward under the elastic reset action of the support spring and always fits with the paper roll. On the one hand, it can provide certain support for the paper roll, and on the other hand, it can ensure that the paper is in a flat state when being pulled.

[0011] By adopting the above technical solution, when the paper is gradually used up, its diameter gradually decreases, and the support frame moves upward under the elastic reset action of the support spring, and the pressed telescopic rod extends accordingly. When the paper is used up, the movable end of the pressed telescopic rod will press the first touch switch, and the control system will drive the electric push rod to retract, pulling the movable base to the side of the paper storage table close to the equipment body, so as to facilitate the movement of the new paper roll on the paper storage table to the support frame.

[0012] Optionally, the control component also includes a second touch switch, which is arranged on the inner wall of the rod cavity of the push-to-telescopic rod away from the first touch switch, and is electrically connected to the electric push rod through a control system to drive the electric push rod to extend.

[0013] By adopting the above technical solution, when a new paper roll is placed on the support frame, under the action of the gravity of the new paper roll, the support frame moves downward, and the telescopic rod is contracted accordingly.

[0014] Optionally, a placement slot is provided on one side of the top of the paper storage table close to the movable base, a pushing and telescopic rod is provided below the placement slot, and a push plate is provided at the movable end of the pushing and telescopic rod. When the pushing and telescopic rod is in a retracted state, the push plate is flush with the inner bottom wall of the placement slot.

[0015] By adopting the above technical solution, when the mobile base moves to one side of the paper storage table driven by the electric push rod, the telescopic rod is extended, and the push plate pushes the new paper roll in the placement slot out of the placement slot so that it can roll onto the support frame, without the need for workers to move the new paper roll laboriously.

[0016] Optionally, a control bag is provided on the side wall of the paper storage platform close to the support frame, and the control bag is communicated with the rod-free cavity of the push-pull telescopic rod.

[0017] By adopting the above technical solution, when the mobile base moves to one side of the paper storage table driven by the electric push rod, it will squeeze the control bag, press the medium in it into the rodless cavity of the push telescopic rod, drive the push telescopic rod to extend, and push out the new paper roll in the placement slot.

[0018] Optionally, a plurality of rotating rollers are arranged on the support frame at intervals along the extension direction of the electric push rod.

[0019] By adopting the above technical solution, the friction between the paper roll and the support frame is reduced when the paper roll rotates, and the integrity of the paper is further ensured.

[0020] Optionally, the top of the support frame is configured as a curved surface.

[0021] By adopting the above technical solution, the support frame can be more closely fitted to the paper roll, thereby increasing the placement stability of the paper roll and reducing the possibility of the paper roll rolling off the support frame.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When a new paper roll is placed on the support frame, the support spring is compressed under the gravity of the new paper roll. As the paper splicer continues to work, the diameter of the new paper roll gradually decreases.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses an automatic paper changing system of an automatic paper splicer. Figure 1 and Figure 2 The automatic paper changing system of the automatic paper splicer includes a device body 1, a mobile base 2, a paper storage platform 3, an electric push rod 4, a support component 5 and a control component 6. The device body 1 is installed on the ground, and the mobile base 2 is a rectangular parallelepiped and is arranged below the paper roll. The paper storage platform 3 is also fixedly installed on the ground and is located on one side of the device body 1; the electric push rod 4 is arranged in the horizontal direction, and the fixed end of the electric push rod 4 is fixedly installed on the lower side wall of the paper storage platform 3, and the other end is fixedly connected to the side wall of the mobile base 2. The support component 5 and the control component 6 are both arranged on the mobile base 2.

[0033] A placement groove 31 is provided on one side of the top of the paper storage platform 3 close to the equipment body 1, and a new paper roll can be stably placed in the placement groove 31. The side of the top of the paper storage platform 3 away from the equipment body 1 is inclined, and is inclined downward from the side away from the equipment body 1 to the side close to the equipment body 1. A new paper roll is also placed on it. When the new paper roll in the placement groove 31 is taken out, another new paper roll can roll into the placement groove 31 along the top of the paper storage platform 3.

[0034] The support assembly 5 includes a support frame 51, a support spring 52 and a plurality of rotating rollers 53. The top of the support frame 51 is provided with an arc surface, which can fit the paper roll more closely and increase the stability of the paper roll. One end of the support spring 52 is fixedly connected to the top of the mobile base 2, and the other end is fixedly connected to the bottom of the support frame 51. In this embodiment, four support springs 52 are provided. A plurality of rotating rollers 53 are arranged on the support frame 51 at intervals along the extension direction of the electric push rod 4. Each rotating roller 53 is rotatably connected to the support frame 51, which can reduce the friction between the paper roll and the support frame 51 and reduce the possibility of paper damage.

[0035] Therefore, when the paper roll is placed on the support frame 51, the support frame 51 will move downward under the action of the gravity of the paper roll, compressing the support spring 52. As the paper splicer continuously conveys the paper, the diameter of the paper roll decreases, and the support frame 51 will move upward under the elastic restoring action of the support spring 52, always supporting the paper roll.

[0036] Reference Figure 2 and Figure 3 The control assembly 6 includes a pressure-operated telescopic rod 61, a first touch switch 62, and a second touch switch 63. A mounting groove 21 is provided on the top of the mobile base 2. The pressure-operated telescopic rod 61 is installed in the mounting groove 21 along the vertical direction. The fixed end of the pressure-operated telescopic rod 61 is fixedly connected to the inner bottom wall of the mounting groove 21, and the movable end of the pressure-operated telescopic rod 61 is fixedly connected to the bottom of the support frame 51. In this embodiment, four pressure-operated telescopic rods 61 are also provided, and they correspond to the support springs 52 one by one. The movable end of the pressure-operated telescopic rod 61 is penetrated by the support springs 52.

[0037] The first touch switch 62 is installed on the inner wall of the rodless cavity of the pressing telescopic rod 61 away from the support frame 51, and the second touch switch 63 is installed on the inner wall of the rod cavity of the pressing telescopic rod 61 close to the support frame 51. The first touch switch 62 and the second touch switch 63 are both electrically connected to the electric push rod 4 through the control system. When the first touch switch 62 is activated, the control system drives the electric push rod 4 to retract; when the second touch switch 63 is activated, the control system drives the electric push rod 4 to extend.

[0038] As the diameter of the paper roll gradually decreases, the support frame 51 moves upward under the elastic reset action of the support spring 52, driving the push-pull telescopic rod 61 to extend. When the paper roll is used up, the movable end of the push-pull telescopic rod 61 will press the first touch switch 62, and the control system will drive the electric push rod 4 to retract, and pull the mobile base 2 to the side of the paper storage table 3 close to the device body 1, so as to facilitate the movement of the new paper roll on the paper storage table 3 to the support frame 51. When the new paper roll is placed on the support frame 51, the support frame 51 will move downward under the gravity of the new paper roll, and the push-pull telescopic rod 61 will shrink accordingly. The movable end of the push-pull telescopic rod 61 will press the second touch switch 63. At this time, the control system drives the electric push rod 4 to extend, and resets the mobile base 2, so that the new paper roll can be installed smoothly.

[0039] Reference Figure 1 and Figure 4 In addition, a clearance groove 32 is provided at the bottom of the placement groove 31, and a push-up telescopic rod 7 is arranged in the clearance groove 32. The fixed end of the push-up telescopic rod 7 is fixedly connected to the inner bottom wall of the clearance groove 32, and the movable end of the push-up telescopic rod 7 is fixedly connected to a push plate 71. When the push-up telescopic rod 7 is in a retracted state, the push plate 71 is flush with the inner bottom wall of the placement groove 31. A control capsule 8 is installed on the side wall of the paper storage table 3 close to the equipment body 1. When no paper roll is placed on the support frame 51, the support frame 51 and the control capsule 8 are at the same horizontal height. It should be noted that the control capsule 8 is connected to the rodless cavity of the push-up telescopic rod 7.

[0040] When the paper roll is used up, the mobile base 2 is pulled by the electric push rod 4 to the side of the paper storage table 3 close to the equipment body 1, which will squeeze the control capsule 8 and press the medium in the control capsule 8 into the rodless cavity of the push-lift telescopic rod 7, driving the push-lift telescopic rod 7 to extend, and the push plate 71 pushes out the new paper roll placed in the placement slot 31, so that it falls on the support frame 51, and no workers need to carry it.

[0041] The implementation principle of the automatic paper changing system of the automatic paper splicer in the embodiment of the present application is as follows: when the paper roll is used up, the support frame 51 moves upward under the elastic reset action of the support spring 52, driving the push-pushing telescopic rod 61 to extend, and the movable end of the push-pushing telescopic rod 61 will press the first touch switch 62, and the control system will drive the electric push rod 4 to retract, and pull the mobile base 2 to the side of the paper storage table 3 close to the device body 1. During the movement, the mobile base 2 will squeeze the control capsule 8, press the medium in the control capsule 8 into the rodless cavity of the push-pushing telescopic rod 7, drive the push-pushing telescopic rod 7 to extend, and the push plate 71 will push out the new paper roll placed in the placement slot 31, so that it falls on the support frame 51. At this time, the support frame 51 moves downward under the gravity of the new paper roll, and the push-pushing telescopic rod 61 shrinks accordingly, and the movable end of the push-pushing telescopic rod 61 will press the second touch switch 63, and the control system will drive the electric push rod 4 to extend, so that the mobile base 2 is reset, and the worker can install the new paper roll on the device body 1. There is no need for workers to carry the paper during the entire process, which saves time and effort and reduces the possibility of paper damage.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
