Specific embodiments

[0027] The core of the present invention is to provide a filter screen sheet cutting device to reduce the deviation in the processing of filter screen sheets.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0029] Please refer to Figures 1 to 4 , a filter screen sheet cutting device disclosed by the present invention includes a conveying mechanism 100, a position detection mechanism 200, a reverse pushing mechanism 300, a shearing mechanism 400 and a control mechanism. Among them, the conveying mechanism 100 is used to convey filter screen strips, and the conveying mechanism 100 has a feeding end and a discharging end; the position detection mechanism 200 is used to respond to the arrival of the filter screen strips, and the position detection mechanism 200 is arranged in the conveying direction of the transmission mechanism; the reverse pushing mechanism 300 is used to push the filter screen strips to move a first preset distance, and the pushing direction of the reverse pushing mechanism 300 is opposite to the conveying direction of the conveying mechanism 100; the shearing mechanism 400 is used to shear the filter screen strips, and the shearing mechanism 400 is arranged at the discharging end of the conveying mechanism 100; when the filter screen strips are conveyed to the position detection mechanism 200, the control mechanism controls the conveying mechanism 100 to stop conveying and controls the shearing mechanism 400 to perform a shearing operation after the reverse pushing mechanism 300 executes a pushing operation to shear the filter screen strips into filter screen sheets.

[0030] Using the filter screen sheet cutting device of the present invention, the conveying mechanism 100 conveys the filter screen strip along the conveying direction. When the filter screen strip reaches the position of the in-place detection mechanism 200, the in-place detection mechanism 200 responds, and the control mechanism controls the conveying mechanism 100 to stop conveying and controls the shearing mechanism 400 to perform a shearing operation after the pushing mechanism 300 executes a pushing operation to cut the filter screen strip into filter screen sheets. Therefore, by using the filter screen sheet cutting device of the present invention, the ends of the filter screen strips can be aligned under the push of the pushing mechanism 300, thereby reducing the deviation during the processing of the filter screen sheets.

[0031] It should be noted that the above-mentioned conveying mechanism 100 is a belt conveying mechanism 100 or a conveying roller conveying mechanism 100, and any structure capable of conveying the filter screen strip is within the protection scope of the present invention. In one example of the present invention, the conveying mechanism 100 includes conveying rollers. When the conveying mechanism 100 performs a conveying operation, the conveying rollers convey the filter screen strip. When the pushing mechanism 300 performs a pushing operation, the conveying mechanism 100 stops conveying. Further, in order to improve the stability of conveying, the conveying mechanism 100 further includes pressing rollers 101 that cooperate with the conveying rollers. When the conveying mechanism 100 performs a conveying operation, the pressing rollers 101 clamp the filter screen strip; when the pushing mechanism 300 performs a pushing operation, the pressing rollers 101 release the filter screen strip.

[0032] The conveying rollers have a plurality of conveying stations arranged side by side along the conveying direction, and each conveying station conveys one filter screen strip. Optionally, the number of conveying stations is two.

[0033] The function of the shearing mechanism 400 is to cut the filter screen strip into filter screen sheets. The shearing mechanism 400 is a traditional shearing structure, and any structure capable of completing the shearing operation is within the protection scope of the present invention. The in-place detection mechanism 200 can also be arranged between the conveying mechanism 100 and the shearing mechanism 400, or the shearing mechanism 400 is located between the in-place detection mechanism 200 and the conveying mechanism 100, and the distance between the in-place detection mechanism 200 and the shearing mechanism 400 is a second preset distance, and the difference between the second preset distance and the first preset distance is the length of the filter screen sheet. The present invention preferably adopts the latter method, in which case, the length of the obtained filter screen sheet is more direct.

[0034] The function of the reverse pushing mechanism 300 is to push the filter screen strip. Among them, the pushing direction of the reverse pushing mechanism 300 is opposite to the conveying direction of the conveying mechanism 100. The reverse pushing mechanism 300 is a mechanism capable of outputting linear motion. For example, a lead screw structure, a linear motor or a piston cylinder. Among them, when it is a piston cylinder, it can be a cylinder 302 structure or a hydraulic cylinder structure. As long as it is a mechanism capable of outputting linear motion, it is within the protection scope of the present invention. In one example of the present invention, the reverse pushing mechanism 300 includes a pushing base 301 and a cylinder 302. Among them, the pushing base 301 is provided with a pushing cavity 3012 and a pushing port 3011 is provided on one side of the pushing base 301 close to the shearing mechanism 400. The in-place detection mechanism 200 is arranged at the pushing port 3011; the extending end of the cylinder 302 pushes the filter screen strip through the pushing cavity 3012.

[0035] Furthermore, the reverse pushing mechanism 300 further includes a pushing block 303 arranged at the telescopic end of the cylinder 302, and the pushing block 303 is slidably arranged in the pushing cavity 3012. A plurality of pushing stations cooperating with the filter screen strip are arranged on the pushing block 303.

[0036] Preferably, there are a plurality of pushing stations arranged side by side to correspond to the conveying stations.

[0037] In order to prevent the filter screen strip from sliding during the shearing operation, the filter screen sheet cutting device further includes a locking mechanism 500 arranged between the shearing mechanism 400 and the reverse pushing mechanism 300 and used for locking the filter screen strip.

[0038] The function of the in-place detection mechanism 200 is to detect whether the filter screen strip is in place. When the filter screen strip is in place, the in-place detection mechanism 200 generates an in-place signal and sends this signal to the control mechanism. Among them, the in-place detection mechanism 200 can be an in-place detection switch, an in-place sensor, a laser sensor, an infrared sensor, etc., institutions capable of detecting in-place; the control mechanism conducts coordinated control. The control mechanism is an external controller, or coordinated control is performed based on multiple control mechanisms of the filter screen sheet cutting device itself. The controller obtains signals corresponding to the filter screen sheet cutting device to control the corresponding actuators to perform corresponding operations.

[0039] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same and similar parts among the embodiments can be referred to each other.

[0040] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
