Description

Technical Field

[0001] The present application relates to the technical field of composite film preparation, and in particular to a composite film rewinding device. Background Art

[0002] Composite film rewinding device is a device used to wind composite film (materials made of different materials stacked together). It is usually used in the packaging industry to manufacture various types of packaging materials, such as plastic bags, food packaging bags, medical packaging films, etc. Composite film rewinding device can achieve fast, efficient and accurate winding of composite film to meet different packaging requirements. At the same time, the device can also reduce the labor intensity of manual operation and improve production efficiency and packaging quality.

[0003] In the Chinese patent application number 202320334714.0, a composite film rewinding device is disclosed. By setting a tensioning roller and a first baffle, the composite film can be initially corrected during the conveying process of the composite film, thereby reducing the deflection of the winding drum during the subsequent transportation and winding process, and avoiding the phenomenon of curling or wrinkling of the edge of the composite film due to excessive deflection during the winding process even after passing through the second baffle.

[0004] With regard to the above-mentioned related technologies, the inventors believe that, in actual use, the above-mentioned device corrects the composite film by moving two sets of correction plates and controlling the distance between the correction plates. However, the winding drum is driven by a motor, and the motor will vibrate during operation. In addition, the correction plates are installed on the winding drum and the tensioning roller through sliders and slide grooves, which can easily cause the correction plates to move, thereby causing the distance between the two sets of correction plates to change, and losing the correction effect.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] The composite film rewinding device provided in the present application adopts the following technical solution:

[0008] A composite film rewinding device comprises a base plate, two groups of support plates are symmetrically installed on the top of the base plate, a winding drum and a tensioning roller are arranged on the support plates, a support beam is fixedly installed between the support plates, a telescopic cylinder is installed through the support beam, a support frame is fixedly installed on the bottom of the telescopic cylinder, the tensioning roller is movably installed on the support frame, the tensioning roller and the winding drum are both provided with a correction mechanism, a guide groove is opened on the support frame, a moving groove is arranged on the support plate, and a positive and negative screw rod of the moving groove is arranged on the support frame.

[0009] Preferably, the deviation correction mechanism on the tensioning roller comprises two sets of deviation correction plates 1 movably fitted on the tensioning roller, and a guide block cooperating with the guide groove is fixedly mounted on the deviation correction plate 1.

[0010] Preferably, the forward and reverse screw rods 1 are rotatably mounted on the support frame, and the forward and reverse screw rods 1 cooperate with the two groups of guide blocks.

[0011] Preferably, a motor is fixedly mounted on the support plate, a rotating shaft penetrating the support plate is mounted on the output end of the motor, and the winding drum is detachably mounted on the rotating shaft.

[0012] Preferably, the deviation correction mechanism on the winding drum comprises two sets of deviation correction plates 2 movably fitted on the winding drum, and two positive and negative screw rods cooperating with the deviation correction plates 2 are rotatably arranged on the support plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By rotating the forward and reverse screw rods 1 and cooperating with the guide blocks and guide grooves, the forward and reverse screw rods 1 drive the two groups of deflection correction plates 1 to move in opposite directions, so as to adjust the distance between the two groups of deflection correction plates 1. By rotating the forward and reverse screw rods 2, since the deflection correction plates 2 are mounted on the winding drum, when the forward and reverse screw rods 2 rotate, the two groups of deflection correction plates 2 are driven to move in opposite directions through the guiding effect of the winding drum, so that the distance between the deflection correction plates 2 is equal to the distance between the deflection correction plates 1, thereby completing the deflection correction effect on the composite film. The forward and reverse screw rods 1 and 2 are used to limit the deflection correction plates 1 and 2 respectively to prevent them from shifting due to vibration, thereby optimizing the deflection correction effect.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a composite film rewinding device. Figure 1-3 , a composite film rewinding device comprises a bottom plate 1, two groups of support plates 2 are symmetrically installed on the top of the bottom plate 1, and a winding drum 3 and a tensioning roller 4 are arranged on the support plate 2, characterized in that: a support beam 5 is fixedly installed between the support plates 2, a telescopic cylinder 6 is installed through the support beam 5, a support frame 7 is fixedly installed at the bottom of the telescopic cylinder 6, the tensioning roller 4 is movably installed on the support frame 7, and a correction mechanism is arranged on the tensioning roller 4 and the winding drum 3, a guide groove 9 is opened on the support frame 7, a moving groove 11 is arranged on the support plate 2, and a positive and negative screw rod 12 of the moving groove 11 is arranged on the support frame 7, and the correction mechanism on the tensioning roller 4 comprises two groups of correction plates 8 movably fitted and sleeved on the tensioning roller 4, a guide block 10 cooperating with the guide groove 9 is fixedly installed on the correction plate 8, and the positive and negative screw rods 12 are rotatably installed on the support frame 7, and the positive and negative screw rods 12 cooperate with the two groups of guide blocks 10;

[0021] By adopting the above technical solution, the forward and reverse screws 12 are rotated, and the guide blocks 10 and the guide grooves 9 are cooperated, so that the forward and reverse screws 12 drive the two sets of correcting plates 8 to move in opposite directions, so as to adjust the distance between the two sets of correcting plates 8, and then correct the composite film on the tensioning roller 4. By controlling the extension and retraction of the telescopic cylinder 6, the telescopic cylinder 6 cooperates with the support frame 7 to drive the tensioning roller 4 to rise and fall, so as to apply different tensions to the composite film.

[0022] Reference Figure 2-3 A motor 13 is fixedly mounted on the support plate 2, a rotating shaft 14 penetrating the support plate 2 is mounted on the output end of the motor 13, the winding drum 3 is detachably mounted on the rotating shaft 14, the deviation correction mechanism on the winding drum 3 includes two sets of deviation correction plates 15 movably fitted on the winding drum 3, and a positive and negative screw rod 16 cooperating with the deviation correction plate 15 is rotatably arranged on the support plate 2;

[0023] By adopting the above technical solution, the forward and reverse screw rods 16 are rotated. Since the deflection correction plate 15 is sleeved on the winding drum 3, and the deflection correction plate 15 and the winding drum 3 are movably connected, the movements are independent of each other. When the forward and reverse screw rods 16 are rotated, the two groups of deflection correction plates 15 are driven to move in the opposite direction through the guiding effect of the winding drum 3, so that the distance between the deflection correction plates 15 is equal to the distance between the deflection correction plates 18, thereby achieving the deflection correction effect of the composite film, and the deflection correction plate 18 is limited by the forward and reverse screw rods 12, and the deflection correction plate 15 is limited by the forward and reverse screw rods 16 to prevent it from being offset due to vibration, thereby optimizing the deflection correction effect.

[0024] The implementation principle of a composite film rewinding device according to the embodiment of the present application is as follows: by rotating the forward and reverse screws 12, in cooperation with the guide block 10 and the guide groove 9, the forward and reverse screws 12 drive the two groups of deflection correction plates 18 to move in the opposite direction, so as to adjust the distance between the two groups of deflection correction plates 18, and rotating the forward and reverse screws 2 16. Since the deflection correction plates 2 15 are sleeved on the winding drum 3, when the forward and reverse screws 2 16 rotate, the two groups of deflection correction plates 2 15 are driven to move in the opposite direction through the guiding effect of the winding drum 3, so that the distance between the deflection correction plates 2 15 is equal to the distance between the deflection correction plates 1 8, thereby completing the deflection correction effect of the composite film, and the forward and reverse screws 12 and the forward and reverse screws 2 16 are used to limit the deflection correction plates 1 8 and the deflection correction plates 2 15 respectively to prevent them from being offset due to vibration, thereby optimizing the deflection correction effect. By controlling the telescopic cylinder 6 to extend and retract, the telescopic cylinder 6 cooperates with the support frame 7 to drive the tensioning roller 4 to rise and fall, so as to apply different tensions to the composite film.
