[0002] Casting machine is an important equipment for producing various plastic films. When manufacturing various plastic films, the film needs to be pressed by embossing roller after it is extruded from the die head, so as to process the film that meets the production requirements. For films with different processing requirements, embossing rollers with different patterns are required. As a key component of the casting machine, the quality and replacement efficiency of the embossing roller directly affect the production efficiency and product quality.

[0003] At present, the replacement of embossing rollers is mainly done manually or with simple mechanical devices. When replacing, the machine usually needs to be stopped, and then part of the structure of the casting machine needs to be disassembled, and then it needs to be replaced manually or with simple lifting equipment. This method is not only time-consuming and labor-intensive, but also easily causes safety hazards to the hands of personnel, so there is room for improvement. Utility Model Content

[0019] By adopting the above technical solution, the hook hooks the embossing roller body, and the motor is controlled to drive the screw to rotate, thereby driving the slide plate to move. The movement of the slide plate drives the hook and the embossing roller body to move together, thereby realizing the transfer operation of the embossing roller body, making it convenient to subsequently install the embossing roller to be replaced on the mounting frame, which is easy to operate and highly practical.

[0020] Preferably, the hanging frame includes a hanging plate and a support column, the support column is fixedly connected to the casting machine body, a driving cylinder is arranged in the support column, the hanging plate is fixedly connected to the driving cylinder, the screw rod is rotatably carried on the hanging plate, and the control motor and the guide rod are both fixed on the hanging plate.

[0021] By adopting the above technical solution, the driving cylinder drives the lifting plate to rise and fall, thereby driving the hook to lift the embossing roller body, reducing the need for operators to adjust the hook and improving convenience.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: when the embossing roller body needs to be replaced, the driving motor slides away from the end of the embossing roller body, the clamping block on the driving motor pulls out of the clamping groove at one end of the embossing roller body to release the clamping connection with each other, and the lifting mechanism lifts the embossing roller body. During the lifting process, the edge of the arc-shaped opening guides the movement of the embossing roller, making the lifting more stable and reducing the situation where the operator disassembles part of the mechanism of the casting machine.

The horizontal movement of the slide plate 20 can drive the hook 32 to move horizontally. When the hook 32 is hoisted on the embossing roller body 2, it can drive the embossing roller body 2 to move horizontally.

[0032] The implementation principle of a tape casting machine that facilitates replacement of embossing rollers in the embodiment of the present application is as follows:

[0033] When the embossing roller body 2 needs to be replaced, the driving cylinder 17 drives the hanging plate 311 to descend, so that the hook 32 is just located on one side of the embossing roller body 2. The operator hooks the hook 32 to the embossing roller body 2, and the driving motor 9 and the sliding frame 11 slide away from the end of the embossing roller body 2 at the same time. The clamping block 10 on the driving motor 9 pulls out the clamping groove 7 at one end of the embossing roller body 2 and releases the clamping connection with each other, and the other end of the embossing roller body 2 is separated from the bearing 12 on the sliding frame 11. The driving cylinder 17 drives the hanging plate 311 to rise to a certain height, and at this time, the embossing roller body 2 slides along the edge of the arc-shaped opening 6 and rises to a certain height. The control motor 18 drives the screw 19 to rotate, and the rotation of the screw 19 drives the slider to move horizontally. The horizontal movement of the slider drives the hook 32 and the embossing roller body 2 to move horizontally together, thereby transferring the embossing roller body 2 to one side of the casting machine. At this time, the driving cylinder 17 drives the lifting plate 311 to descend, and the operator separates the hook 32 from the embossing roller body 2, and hooks the hook 32 onto the embossing roller body 2 to be replaced, and the replaced embossing roller body 2 is placed on the transport trolley.

[0034] The driving cylinder 17 then drives the hanging plate 311 to rise to a certain height, and the control motor 18 drives the screw 19 to rotate, so that the hook 32 and the embossing roller body 2 move horizontally together, so as to transfer the embossing roller body 2 to the top of the casting machine, and the driving cylinder 17 drives the hanging plate 311 to descend, so that the embossing roller body 2 descends into the arc opening 6 and slides to the bottom. The driving motor 9 and the sliding frame 11 slide toward the end of the embossing roller body 2 at the same time, and the clamping block 10 on the driving motor 9 is inserted into the clamping groove 7 at one end of the embossing roller body 2 and is engaged with each other, and the other end of the embossing roller body 2 is inserted into the bearing 12 on the sliding frame 11, and the driving motor 9 can drive the embossing roller body 2 to rotate.

[0035] 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.
