Description

Technical Field

[0001] This utility model relates to a mechanism for separating a sheet from a whole film. Background Technology

[0002] Existing labels or decorative films used on packaging containers and cups are generally small in area. Their shape is typically achieved by die-cutting from a larger film. A given unit area of ​​a large film can be cut into multiple decorative film sheets. Currently, these film sheets are usually separated from the large film using a peeling mechanism, which mainly consists of a support roller and a pressure roller. The cooperation between the pressure roller and the roller separates the sheet from the large film. However, the cut film is prone to misalignment, deformation, or stretching, affecting the subsequent winding of waste materials and the precise die-cutting of preceding processes, making it difficult to improve production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a film sheet peeling device that can effectively improve production efficiency.

[0004] The present invention achieves the above objectives as follows:

[0005] A film sheet peeling device includes a bracket, on which a belt roller is mounted. A power drive mechanism is mounted on one of the belt rollers. A belt surrounds the belt roller to form a film support surface. A pressing roller is provided at the rear lower part of the belt movement direction to press the film against the belt surface.

[0006] The belt rollers consist of four rollers that tension the belt into a trapezoidal structure with a longer top and shorter bottom. The inclined surface is located behind the belt in the direction of movement, and the belt rollers that drive the belt to rotate are located at the upper corner of the inclined surface.

[0007] The pressure roller is located below the inclined surface of the belt.

[0008] A belt support block is provided below the thin film support surface.

[0009] The outer surface of the belt is rough and covered with pits.

[0010] Among the belt rollers wound with the belt, one can be radially adjusted and moved. This roller is located in front of and below the direction of belt movement. Both ends of the roller are fixed with retaining rings. The retaining rings have radial screw holes. A protrusion is fixed at the position opposite to the radial screw holes. The protrusion has a through hole for the screw to pass through. The screw passes through the through hole and can be connected to the radial screw hole.

[0011] Among them, a pressure roller is provided at the rear and upper part of the belt movement direction to press down the film waste. The pressure roller is installed on the horizontal support, and its position can be adjusted and fixed along the horizontal support.

[0012] The transverse support includes vertical connecting blocks on both sides, and two horizontal bars with gaps are installed between the two vertical connecting blocks. The pressure roller is connected to a cylinder, which is mounted on a snap-fit ​​block. The snap-fit ​​block has a protrusion that is embedded in the gap between the two horizontal bars and is connected and fixed to the horizontal bars by a connector.

[0013] The conveyor is equipped with a sheet conveying mechanism at the rear of the belt. The conveying mechanism is mainly composed of a conveyor belt. A pressing wheel shaft is provided at the front of the conveyor belt. The two ends of the pressing wheel shaft are mounted on fixed blocks on both sides. Several symmetrical support grooves for supporting the pressing wheel shaft are provided on the inner side of the two fixed blocks.

[0014] It includes a bracket, on which a belt roller is mounted. A power drive mechanism is mounted on one of the belt rollers. The belt wraps around the belt roller to form a film support surface. A pressing roller is provided at the rear lower part of the belt movement direction to press the film against the belt surface.

[0015] The beneficial effects of this utility model are: because a thin film support surface is left on the belt surface surrounding the belt roller, and a pressing roller is provided at the rear lower part of the belt movement direction to press the film against the belt surface, the film and the belt can maintain good contact, so that there is sufficient friction between the two, avoiding the film from shifting, deforming or stretching after cutting, ensuring that the preceding and following processes can be carried out smoothly, and improving production efficiency. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Fig. 1 This is a three-dimensional structural diagram of the present invention;

[0018] Fig. 2 This is a three-dimensional structural diagram of the present invention after removing some components;

[0019] Fig. 3 This is a three-dimensional structural diagram of the present invention from another angle after some components have been removed. Detailed Implementation

[0020] Reference Figs. 1 to 3A film sheet peeling device includes a support 1, on which a belt roller 2 is mounted. A power drive mechanism 3 is mounted on one of the belt rollers 2. The device is characterized in that a belt 4 surrounds the belt roller 2 to form a film support surface 41, and a pressing roller 5 is located at the rear lower end of the belt 4 in the direction of belt movement to press the film against the belt surface. Because a film support surface is provided on the belt surface surrounding the belt roller, and a pressing roller is located at the rear lower end of the belt movement direction to press the film against the belt surface, good contact between the film and the belt is maintained, ensuring sufficient friction between them. This prevents the cut film from shifting, deforming, or stretching. When the cut film moves to the rear of the belt, the sheet naturally falls off, ensuring smooth operation of the preceding and following processes and improving production efficiency.

[0021] The belt rollers 2 consist of four rollers that tension the belt 4 into a trapezoidal structure, longer at the top and shorter at the bottom. An inclined surface 42 is located behind the belt in the direction of movement, and the belt rollers 2 that drive the belt rotation are located at the upper corner of the inclined surface 42. This arrangement effectively increases the contact area between the belt rollers 2 and the belt, increasing friction and ensuring that the belt rollers 2 smoothly drive the belt, preventing slippage and facilitating smooth operation of subsequent processes.

[0022] Similarly, in order to have a larger contact area between the film and the belt and to prevent the film from slipping, the pressing roller 5 is located below the belt inclined surface 42.

[0023] In addition, to prevent the upper surface of the belt from concave downwards and to ensure that the upper surface of the belt or the film is on the same plane so that the cut sheet can be easily removed, a belt support block 6 is provided below the film support surface 41.

[0024] To further prevent the film from slipping on the belt, the outer surface of the belt 4 is a rough surface covered with pits.

[0025] To facilitate adjustment of belt tension, one of the belt rollers 2 wound with the belt is radially adjustable. This roller is located slightly below and in front of the belt's direction of movement. Both ends of the roller are fixed with retaining rings 15, each with a radial screw hole 16. A protrusion 17 is fixed opposite the radial screw hole 16, and the protrusion 17 has a through hole 18 for a screw to pass through. The screw passes through the through hole 18 and connects to the radial screw hole 16. Rotating this screw adjusts the belt tension.

[0026] To further increase the friction between the film and the belt and prevent deviation, deformation, or stretching, a pressure roller 7 is provided above and behind the belt in the direction of belt movement to press down the film waste. The pressure roller 7 is mounted on a transverse support 8, and its position can be adjusted and fixed along the transverse support 8.

[0027] The horizontal support 8 includes vertical connecting blocks 9 on both sides, with two crossbars 81 spaced apart between the two vertical connecting blocks 9. The pressure roller 7 is connected to a cylinder 10, which is mounted on a locking block 11. The locking block 11 has a protrusion 111 that is embedded in the gap between the two crossbars 81 and is fixed to the crossbars 81 by a connector. In this way, the entire set of accessories connected to the pressure roller 7 can be easily slid along the crossbars to adjust its position.

[0028] Furthermore, a sheet conveying mechanism is provided behind the belt. This conveying mechanism mainly consists of a conveyor belt 12. A pressing wheel shaft 13 is located at the upper front of the conveyor belt 12. The two ends of the pressing wheel shaft 13 are mounted on fixed blocks 14 on both sides. Several symmetrical support grooves 141 for supporting the pressing wheel shaft 13 are provided on the inner side of the two fixed blocks 14. The pressing wheel shaft 13 can flatten the dislodged sheet onto the conveyor belt 12, allowing the conveyor belt to smoothly deliver the sheet and preventing the sheet from falling or arbitrarily arranging during transportation.
