[0014] To drive the first cylinder 11, a wire reel 14 driven by a second motor is provided above each of the second cylinders 13. A rope 15 is wound around and fixed to the wire reel 14, and the free end of the rope 15 is fixedly connected to the wall of the corresponding first cylinder 11.

[0015] To facilitate the sliding installation of the first cylinder 11 on the base plate 1, a slider is provided at the bottom of the first cylinder 11, and a chute for the installation and sliding of the slider is provided on the base plate 1.

[0016] To facilitate the installation and unloading of the templates, a plurality of horizontal front-back direction rollers 16 are evenly distributed at intervals on the second frame 8.

[0017] The specific working process of the present invention: The initial state of the device is that the first motor 5 stops rotating, and the wire reel 14 loosens the rope 15. At this time, under the action of the tension spring 12, the gas in the first cylinder 11 is squeezed and conveyed into the corresponding second cylinder 13. The piston rod of the second cylinder 13 extends and moves the corresponding first cylinder 11 towards the support column 2. At this time, the piston rod in the first cylinder 11 retracts, so that the first motor 5 hinged to the upper end of the piston rod of the first cylinder 11 moves downward. The output shaft of the first motor 5 is coaxial with the corresponding connecting rod 3, so that when the first motor 5 swings downward, the connecting rod 3 swings downward around the hinge axis. During this process, the two first frames 6 open. Under the action of a plurality of compression springs 10, the rollers 16 on the second frame 8 protrude between the two first frames 6. Place the two templates to be cleaned on the plurality of rollers 16 in the corresponding first frame 6, so that the surfaces to be cleaned of the two templates face each other. After completion, drive the second motor to drive the wire reel 14 to tighten the rope 15 to realize the movement of the first cylinder 11 towards the second cylinder 13. During this process, the gas in the second cylinder 13 is squeezed into the first cylinder 11, so that the piston rod of the first cylinder 11 extends and lifts the first motor 5 upward. During this process, the two first frames 6 gradually merge. At the same time, under the action of the compression spring 10, the second frame 8 and the rollers 16, after the two templates come into contact, they can maintain stable contact under the elastic deformation of the compression spring 10, and finally the surfaces to be cleaned of the two templates are completely attached and realize flexible contact and extrusion under the action of the compression spring 10. At this time, the limit rod 7 can ensure the limitation of the templates. After the surfaces to be cleaned of the two templates are completely attached, turn on the two first motors 5, so that the two first motors 5 drive the corresponding sleeves 4 to swing reciprocally around the connecting rod 3, thereby driving the two first frames 6 to swing reciprocally. During this process, the reciprocating driving directions of the two first motors 5 are opposite, ensuring that the surfaces to be cleaned of the two mutually contacting templates can reciprocally contact and rub, so as to realize the synchronous cleaning of the two templates. During the movement of the two templates, the rotation angle of the first motor 5 ensures that the two templates cannot be separated from each other.

[0018] After the template cleaning is completed, the first motor 5 is turned off, and the two first brackets stop reciprocating swing. The second motor rotates in reverse to relax the rope 15. Under the reset action of the tension spring 12, the support column 2 in the first cylinder 11 moves, and the piston rod in the first cylinder 11 retracts inward. At this time, the two first frames 6 gradually open, and the operator can manually take out the two cleaned templates and replace them with the next group of templates to be cleaned, and then the template cleaning can be carried out again.

[0019] The advantages of this device compared with traditional equipment are as follows:

[0020] 1. The device cleans two templates together by squeezing and rubbing the surfaces to be cleaned of the two templates. This cleaning method effectively improves the cleaning efficiency of the templates, which is twice that of ordinary template cleaning equipment.

[0021] 2. When cleaning the templates, this device does not use water, nor does it require a scraper or a roller brush, which avoids the waste of water resources and reduces the wear of abrasives. Therefore, the use cost is lower, and it can also avoid the problem of incomplete template cleaning caused by untimely discovery of abrasive wear.

[0022] 3. When the two templates are tilted and close to each other under the action of the compression spring 10, the compression spring 10 can provide a flexible force. During this process, the two templates can ensure stability when they come into contact, and will not cause the templates to fall off or irreversible deformation, making the device safer to use.

[0023] The invention has novel concept, ingenious structure and strong practicability, and effectively solves the problems of serious waste of water resources in the existing template cleaning equipment, easy wear of the device, incomplete template cleaning and low efficiency.
