Description

Technical Field

[0001] This utility model relates to a label roll fixing mechanism for an instant labeling machine, belonging to the field of labeling machine technology. Background Technology

[0002] In industrial production, instant labeling machines are widely used in food, pharmaceutical, daily chemical, and logistics industries as key equipment for integrating label printing and application. One of the core performance characteristics of such equipment depends on the stability of label roll fixing and operational efficiency. Especially when dealing with heavy label rolls, which typically weigh over 10kg and have a diameter of over 300mm, the design of label roll installation and fixing directly affects the continuous operation capability of the production line, labeling accuracy, and the intensity of manual operation.

[0003] Currently, the label roll fixing method of instant labeling machines has the following problems when adapting to heavy label rolls: the installation and operation are cumbersome and time-consuming. Traditional fixing mechanisms mostly adopt a single-axis support design. When changing heavy label rolls, it is necessary to manually move the roll and accurately align it with the fixing axis. In addition to the need for multiple people to work together, it is also necessary to repeatedly adjust the concentricity of the roll and the axis to avoid radial shaking during high-speed rotation due to installation tilt. This process usually takes a long time for each change. In high-frequency roll changing scenarios such as multi-variety small-batch production, it significantly reduces the effective operating time of the equipment and restricts the efficiency of the production line. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a label roll fixing mechanism for an instant labeling machine, which simplifies the operation process and improves roll changing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a label roll fixing mechanism for an instant labeling machine, characterized in that it includes: a frame, a roll carrier is provided above the frame, and the top of the roll carrier is provided with several sets of mounting slots;

[0006] The frame is equipped with a rotating mechanism for driving the carrier reel to rotate.

[0007] A mounting plate is provided at one lower end of the load reel, and a rotating rod is vertically provided on the mounting plate. A loading frame is fixed to the top of the rotating rod, and a spreading and fixing device is fixed to the midpoint of the top of the loading frame. A lifting groove is provided through the bottom of the mounting groove, and both the lifting groove and the loading frame are cross-shaped.

[0008] The side of the frame is equipped with a lifting mechanism for moving the mounting plate vertically.

[0009] Preferably, the rotating mechanism includes a motor, the output end of which is connected to a rotating column. The rotating column is mounted on the top of the frame and is fixedly connected to the bottom of the carrier reel.

[0010] Preferably, a second motor is provided at the bottom of the mounting plate, and the output end of the second motor is connected to the rotating rod.

[0011] Preferably, the inner diameter of the lifting groove is larger than the outer diameter of the loading frame.

[0012] Preferably, the lifting mechanism includes a third motor, the output end of which is connected to a lead screw. The lead screw is vertically arranged on the side of the frame and is threaded through the mounting plate.

[0013] Preferably, a guide rod is also fixed to the side of the frame, and the guide rod passes through the mounting plate and is slidably connected to it.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By setting up a reel tray, multiple sets of standard rolls can be pre-stored. When the current standard roll is used up, the rotating mechanism quickly rotates the mounting slot of the new standard roll to the loading position. The lifting mechanism and the loading frame work together to achieve quick docking and fixing. No manual handling and alignment is required during replacement, avoiding safety hazards caused by handling heavy objects. Moreover, the single roll change time is shortened from more than 5 minutes in the traditional way to less than 30 seconds, significantly reducing production line downtime. It is especially suitable for high-frequency roll change scenarios of multi-variety small-batch production. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A label roll fixing mechanism for an instant labeling machine includes: a frame 1, a roll carrier 2 is provided above the frame 1, and the top of the roll carrier 2 is provided with several sets of mounting slots 3;

[0024] The frame 1 is equipped with a rotating mechanism 4 for driving the carrier reel 2 to rotate;

[0025] A mounting plate 5 is provided at one lower end of the loading reel 2, and a rotating rod 6 is vertically provided on the mounting plate 5. A loading frame 8 is fixed at the top of the rotating rod 6, and a spreading fixture 9 is fixed at the midpoint of the top of the loading frame 8. A lifting groove 10 is provided through the bottom of the mounting groove 3. Both the lifting groove 10 and the loading frame 8 are cross-shaped.

[0026] The side of the frame 1 is provided with a lifting mechanism 11 for driving the mounting plate 5 to move vertically.

[0027] Furthermore, several sets of mounting slots 3 on the top of the carrier tray 2 are used to pre-store heavy label rolls. Multiple label rolls can be placed into different mounting slots 3 in advance to achieve centralized storage and quick switching of label rolls. The rotating mechanism 4 is used to drive the carrier tray 2 to rotate. When it is necessary to change the label roll, the mounting slot 3 where the target label roll is located is aligned with the loading frame 8 below by rotating the carrier tray 2 to complete the switching of the label roll position. The loading frame 8 is cross-shaped and can pass through the cross-shaped lifting slot 10 at the bottom of the mounting slot 3 under the drive of the lifting mechanism 11 to lift and raise the label roll in the mounting slot 3 from below, realizing the transfer and positioning of the label roll.

[0028] In this embodiment: the rotating mechanism 4 includes a motor 401, the output end of which is connected to the rotating column 402. The rotating column 402 is installed on the top of the frame 1 and is fixedly connected to the bottom of the carrier reel 2.

[0029] Furthermore, the rotating column 402 is connected to the output end of the motor 401, and the other end is fixed to the bottom of the carrier reel 2, so as to transmit the rotational motion of the motor 401 to the carrier reel 2, realize the precise rotational positioning of the carrier reel 2, and ensure that the mounting slot 3 and the loading frame 8 are aligned.

[0030] In this embodiment: a second motor 7 is provided at the bottom of the mounting plate 5, and the output end of the second motor 7 is connected to the rotating rod 6.

[0031] Furthermore, motor 7 can drive the rotating rod 6 and the loading frame 8 to rotate, which is used to adjust the cross-shaped loading frame 8 and drive the standard roll to rotate and release material.

[0032] In this embodiment: the inner diameter of the lifting groove 10 is larger than the outer diameter of the loading frame 8.

[0033] Furthermore, the inner diameter of the lifting groove 10 is larger than the outer diameter of the loading frame 8, ensuring that the loading frame 8 can pass through the lifting groove 10 without obstruction during the lifting process, avoiding jamming or offset of the label roll due to dimensional interference between the two, and ensuring the smoothness of the label roll transfer process.

[0034] In this embodiment: the lifting mechanism 11 includes a motor 1101, the output end of which is connected to a lead screw 1102. The lead screw 1102 is vertically arranged on the side of the frame 1 and is threaded through the mounting plate 5.

[0035] Furthermore, the output end of motor 3101 drives the lead screw 1102 to rotate, thereby realizing the vertical movement of the mounting plate 5 through lead screw transmission.

[0036] In this embodiment: a guide rod 1103 is also fixed on the side of the frame 1, and the guide rod 1103 passes through the mounting plate 5 and is slidably connected to it.

[0037] Furthermore, the guide rod 1103 restricts the lateral sway of the mounting plate 5 when the lifting mechanism 11 drives the mounting plate 5 to move.

[0038] The workflow of this embodiment is as follows: The operator places multiple heavy label rolls into the mounting slots 3 of the carrier reel 2 to prevent them from slipping off when the carrier reel 2 rotates. At this time, the carrier reel 2 is connected to the frame 1 through the rotating column 402 of the rotating mechanism 4 and is in a ready-to-switch state. When the current working label rolls are used up or the type needs to be changed, the motor 1 401 is started to drive the rotating column 402 to rotate, which drives the carrier reel 2 to rotate, so that the mounting slot 3 where the target label roll is located is accurately aligned with the loading rack 8 below. At the same time, the motor 2 7 at the bottom of the mounting plate 5 drives the rotating rod. 6. Rotate and adjust the angle of the cross-shaped loading frame 8 so that it is fully matched with the cross-shaped lifting groove 10 at the bottom of the mounting groove 3. Then start the motor 3 1101 to drive the lead screw 1102 to rotate, which will drive the mounting plate 5 to rise vertically along the guide rod 1103, so that the cross-shaped loading frame 8 passes through the lifting groove 10 and lifts the label roll in the mounting groove 3 from below. When the loading frame 8 is fully inserted into the label roll core, the top expansion retainer 9 will be tightly attached to the label roll core through the tensioning action to achieve radial fixation and prevent the label roll from slipping or shaking when rotating.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
