[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention. The technical solutions of the various embodiments of the present invention can be combined, and the technical features in the embodiments can also be combined to form new technical solutions.

[0029] The utility model provides the following technical solutions:

[0030] As attached Figure 1 , is the main body of the orifice plate film tearing machine 14, which is the existing technology, specifically including:

[0031] Machine body, mucosa reversing and limiting mechanism, adhesive film transfer mechanism, control system, orifice plate transfer mechanism.

[0032] As attached Figure 2 ~Attached Figure 5 As shown, it is an improved solution of the utility model, which is mainly aimed at improving the supporting plate 1 of the orifice plate transfer mechanism in the prior art. The specific structure is as follows:

[0033] Guide rails 13 are arranged on the left and right sides of the carrier plate 1, which are used for sliding on the orifice plate film tearing machine 14, specifically, sliding in the film tearing channel on the orifice plate film tearing machine 14. At the same time, a driving gear bar 8 is arranged under the carrier plate 1, which is meshed with the gear on the orifice plate film tearing machine 14. The gear bar is driven to move forward and backward by the motor, so that the carrier plate 1 slides forward and backward through the guide rails 13.

[0034] At the same time, four L-shaped limit blocks 2 are arranged on one side of the upper end of the carrying plate 1, forming an orifice plate placement area for placing the orifice plate.

[0035] The improved part is that there is a movable buckle 3 on the orifice plate placement area, which is located between the two limit blocks 2 and will not interfere with the card plate. The driving of the movable buckle 3 is also designed in this technical solution, specifically:

[0036] A through hole 5 is provided on the carrier plate 1, and the movable buckle 3 is slidably arranged in the through hole 5. At the same time, a spring positioning pin 6 is provided on the inner wall of the movable through hole 5, and a compression spring 7 is sleeved on the spring positioning pin 6, and the compression spring 7 is in contact with the movable buckle 3;

[0037] The lower part of the movable buckle 3 is fixedly connected to one end of the buckle linkage plate 4 by a bolt. In order to limit the left and right sides of the buckle linkage plate 4, a matching long groove is provided under the supporting plate 1 for the buckle linkage plate 4, which can make the buckle linkage plate 4 slide forward and backward. At the same time, in order to prevent the buckle linkage plate 4 from shifting up and down, a connecting plate anti-detachment cover 12 is fixedly provided under the supporting plate 1. The connecting plate anti-detachment cover 12 contacts the buckle linkage plate 4 and is used to limit the buckle linkage plate 4 up and down, so that the buckle linkage plate 4 can only move forward and backward. Therefore, the movable buckle 3 can move forward and backward under the forward and backward sliding of the buckle linkage plate 4, thereby realizing the clamping and loosening of the card plate.

[0038] In order to achieve the linkage effect, a positioning groove 10 is provided on the end face of the carrier plate 1, and a positioning hole 9 is provided below the buckle linkage plate 4. The positioning hole 9 and the positioning groove 10 are on the same straight line, and the length of the positioning groove 10 is greater than the length of the positioning hole 9. At the same time, a positioning electromagnet 11 is provided at the position corresponding to the orifice plate tearing machine 14, and the extended rod of the positioning electromagnet 11 can be inserted into the positioning hole 9 and the positioning groove 10. After insertion, the continued movement of the carrier plate 1 will cause the buckle linkage plate 4 to be misaligned with the carrier plate 1, thereby driving the forward and backward movement of the active buckle 3. When the positioning electromagnet 11 is separated from the positioning hole 9, the active buckle 3 will be reset under the action of the compression spring 7, and reversely drive the movement of the buckle linkage plate 4.

[0039] Working principle and process of this utility model:

[0040] When the carrier plate 1 is driven by the driving gear bar 8 to make the positioning hole 9 move to the position of the positioning electromagnet 11, the telescopic rod of the positioning electromagnet 11 rises, passes through the positioning hole 9 and the positioning slot 10, and clamps the buckle linkage plate 4.

[0041] At this time, the carrying plate 1 retreats a certain distance. Since the length of the positioning groove 10 on the carrying plate 1 is greater than the length of the positioning hole 9 on the buckle linkage, when the carrying plate 1 retreats, the buckle linkage plate 4 does not move. The reaction force of the active buckle 3 connected to the buckle linkage plate 4 compresses the spring 7 and pushes the active buckle 3 in the opposite direction. At this time, the orifice plate can be loosened or placed.

[0042] As attached Figure 6 In the state shown, when the telescopic rod of the positioning electromagnet 11 is retracted, the movable buckle 3 is pushed toward the orifice plate under the action of the restoring force of the compression spring 7 to lock the orifice plate.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
