Description

Technical Field

[0001] This utility model relates to a roll changing device, specifically an automatic roll changing device for dustproof film, belonging to the technical field of film roll material processing equipment. Background Technology

[0002] The winding of dustproof film is of great significance in industrial production. Successfully wound dustproof film rolls offer the following benefits: efficient storage and transportation, improved space utilization, and ease of handling and movement; protection of the product's intrinsic quality, namely maintaining its physical properties and preventing surface damage. Currently, the most common technique for winding dustproof film is using a winding shaft. The winding device rotates the winding shaft to perform the winding. For winding shafts that have reached the standard thickness, a replacement process is required, replacing the existing winding shaft with one now containing the dustproof film. This process involves reinstalling the new winding shaft with the frame, ensuring the rotating structure is securely in place before rotation can occur. However, this process often involves complex hole alignment and the installation of various fasteners, making it cumbersome and affecting the winding efficiency of the dustproof film.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an automatic roll changing device for dustproof film, which has a convenient roll changing process, a simple and reasonable structure, and a wide range of applications.

[0005] The technical solution adopted by this utility model is as follows: an automatic roll-changing device for dustproof film, including a frame; a take-up shaft is provided inside the frame, and a rotating frame for clamping the take-up shaft is also provided inside the frame; a first drive end connected to the rotating frame is provided on the outside of the frame; an elastic spindle mechanism is provided inside the take-up shaft; a second drive end for pushing the elastic spindle mechanism to translate is provided on one side of the rotating frame; and a third drive end connected to the elastic spindle mechanism is provided on the other side of the rotating frame.

[0006] Furthermore, a central hole is coaxially formed on the inner side of the take-up shaft; at least three guide grooves are formed on the inner wall of the central hole; the elastic spindle mechanism includes a shaft body; the shaft body is inserted into the central hole.

[0007] Furthermore, a guide protrusion is provided on the outer side of the shaft; the guide protrusion corresponds one-to-one with the guide groove; the guide protrusion is slidably disposed in the guide groove; a spring is also provided in the guide groove; the spring is connected to the guide protrusion.

[0008] Furthermore, the two ends of the shaft are respectively provided with a first groove and a second groove; the second driving end is a cylinder located outside the rotating frame; the piston end of the cylinder is inserted into the first groove or away from the first groove.

[0009] Furthermore, a keyway is provided on the inner wall of the second groove; the third driving end is a motor; the output shaft end of the motor is provided with a spline; the spline and the keyway are matched with each other.

[0010] Furthermore, the first driving end is a drive motor; one end of the rotating frame is provided with a rotating shaft; the rotating shaft is connected to the first driving end; and a support plate is also provided on the inner side of the rotating frame.

[0011] This invention offers the following advantages: By setting a first driving end, a second driving end, and a third driving end at three positions on the rotating frame, the rotating frame limits the position of the take-up shaft. Subsequently, under the action of the second driving end, the elastic spindle mechanism connects to the second and third driving ends respectively. The elastic spindle mechanism can remain relatively fixed with the third driving end while also rotating relative to the second driving end.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] See Figures 1-3This application discloses an automatic roll-changing device for dustproof film, including a frame 1; a take-up shaft 2 is disposed inside the frame 1, and a rotating frame 3 for clamping the take-up shaft 2 is also disposed inside the frame; a first drive end 11 connected to the rotating frame 3 is disposed on the outer side of the frame 1; an elastic spindle mechanism is disposed inside the take-up shaft 2; a second drive end for pushing the elastic spindle mechanism to translate is disposed on one side of the rotating frame 3; and a third drive end connected to the elastic spindle mechanism is disposed on the other side of the rotating frame 3.

[0018] Furthermore, the take-up shaft 2 has a coaxially formed central hole 2-1 on its inner side; at least three guide grooves 2-11 are formed on the inner wall of the central hole 2-1; the elastic spindle mechanism includes a shaft body 4; the shaft body 4 is inserted into the central hole 2-1.

[0019] Specifically, in this embodiment, the take-up shaft 2 has a central hole 2-1 inside, and a shaft 4 that is coaxial with the take-up shaft 2 is provided in the central hole 2-1; the shaft 4 is the key to the movement of the take-up shaft 2; through the shaft 4 as a conductor, under the action of the second drive end, the entire take-up shaft 2 can be connected to the third drive end through the shaft 4, and the torque of the third drive end is transmitted to the take-up shaft 2 to make it rotate.

[0020] Furthermore, a guide protrusion 4-1 is provided on the outer side of the shaft 4; the guide protrusion 4-1 corresponds one-to-one with the guide groove 2-11; the guide protrusion 4-1 is slidably disposed in the guide groove 2-11; a spring 5 is also provided in the guide groove 2-11; the spring 5 is connected to the guide protrusion 4-1.

[0021] Furthermore, the two ends of the shaft 4 are respectively provided with a first groove 4-2 and a second groove 4-3; the second driving end is a cylinder 6 located outside the rotating frame 3; the piston end of the cylinder 6 is inserted into the first groove 4-2 or away from the first groove 4-2.

[0022] Specifically, in this embodiment, the shaft 4 has a first groove 4-2 and a second groove 4-3 at both ends. When the piston of the cylinder 6, which serves as the second driving end, is working, it will be inserted into the first groove 4-2 and push the shaft 4 to move horizontally along the direction of the guide groove 2-11, so that its other end is close to the third driving end and a torque-transmitting connection is formed.

[0023] Furthermore, the connection between the guide protrusion 4-1 and the guide groove 2-11 ensures that the shaft 4 and the winding shaft 2 can be relatively fixed in the circumferential direction; however, they are relatively movable in the axial direction, which can transmit torsion and switch the connection state with the third drive end.

[0024] Furthermore, a keyway 7 is provided on the inner wall of the second groove 4-3; the third driving end is a motor 8; a spline 9 is provided on the output shaft end of the motor 8; the spline and the keyway 7 are matched with each other.

[0025] Furthermore, the first driving end 4 is a drive motor; one end of the rotating frame 3 is provided with a rotating shaft; the rotating shaft is connected to the first driving end; and a support plate 10 is also provided on the inner side of the rotating frame 3.

[0026] In this embodiment, when the shaft 4 is horizontally pushed by the piston of the cylinder 6, the keyway 7 of the second groove 4-3 at its end will also move horizontally, causing the spline 9 on the output shaft of the motor 8 to be inserted into the keyway 7, so that the motor 8 can transmit torque to the shaft 4; and the shaft 4 is circumferentially fixed to the guide groove 2-11 by the guide protrusion 4-1, so it will also transmit torque to the take-up shaft 2, causing it to rotate.

[0027] Furthermore, since the rotating frame 3 has a support plate 10, when replacing the take-up shaft 2, the entire rotating frame 3 is flipped upward by the first drive end 11 so that it is in a vertical state with the opening facing upward; after the new take-up shaft 2 is placed into the rotating frame 3, it is supported by the support plate 10; thus, the second drive end is aligned with the first groove 4-2.

[0028] Working principle: First, the rotating frame 3 is flipped upwards by the first drive end 11 so that its opening faces upwards. Then, the take-up shaft 2 is placed into the rotating frame 3. Since the size of the rotating frame 3 is designed to match the take-up shaft 2, after the take-up shaft 2 is supported on the support plate 10, the piston of the cylinder 6 on one side of the rotating frame 3 will automatically align with the shaft 4. Then, the cylinder 6 is activated, so that the piston is inserted into the first groove 4-2 at one end of the shaft 4 and pushes the shaft 4 to move horizontally, so that the spline 9 on the motor 8 shaft can be inserted into the keyway 7 of the second groove 4-3. In this case, the rotational torque of the motor 8 can be transmitted to the shaft 4 and the take-up shaft 2 through the spline, so that the take-up shaft 2 rotates. After the current take-up shaft 2 has finished winding, the rotating frame 3 is flipped upwards under the action of the first drive end 11, and then the piston of the cylinder 6 is withdrawn from the first groove 4-2, so that the shaft 4 moves horizontally in the opposite direction under the action of the spring, the spline and the spline groove separate, and the take-up shaft 2 can be removed.

[0029] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
