In order to facilitate understanding of the embodiments of the present application, in the embodiments shown in fig. 1 to 8, the description is given with an example in which the first direction, the second direction, and the third direction are directions perpendicularly intersecting each other, but it should be understood by those skilled in the art that the embodiments of the present application are not limited to the case in which the three directions perpendicularly intersect each other. For convenience of explanation, as shown by the arrows in fig. 1 to 8, the direction of the arrow X is a first direction, the direction of the arrow Y is a second direction, and the direction of the arrow Z is a third direction. The direction along which the arrow Z points in the third direction is sometimes referred to as "upper" and the opposite direction is sometimes referred to as "lower".

In a first aspect of the present application, a paper tearing device is provided for tearing off release paper covered on an adhesive surface of a sheet 100, as shown in fig. 1 to 3, the paper tearing device includes a sheet conveying mechanism 1 and a paper tearing mechanism 2, the sheet conveying mechanism 1 is configured to be capable of carrying the sheet 100 from a side of the sheet 100 covered with the release paper and conveying the sheet 100 along a sheet conveying path, and the sheet conveying mechanism 1 is provided with a paper clamping opening 10 in the sheet conveying path; the paper tearing mechanism 2 comprises a paper tearing chuck 21 and a chuck driving device 22 connected with the paper tearing chuck 21, the chuck driving device 22 can drive the paper tearing chuck 21 to reciprocate between a paper clamping position and a avoiding position avoiding a sheet conveying path through the paper clamping opening 10, the paper tearing chuck 21 can clamp a lug of release paper covered by a sheet 100 reaching the paper clamping opening 10 under the condition of being positioned at the paper clamping position, and the release paper is torn off an adhesive surface in the process that the sheet conveying mechanism 1 continuously conveys the sheet 100 and the paper tearing chuck 21 moves from the paper clamping position to the avoiding position through the paper clamping opening 10.

The sheet 100 is a sheet-like object having an adhesive surface on at least one side and the adhesive surface is covered with release paper, and the embodiment of the present application is used to tear off the release paper on one side to expose the adhesive surface on one side, so that the sheet can be adhered to an object to which the sheet needs to be adhered through the exposed adhesive surface. For example, the sheet 100 may have an adhesive surface on only one side or may have adhesive surfaces on both sides. When one side has an adhesive surface, the sheet 100 is placed so that the release paper covering the adhesive surface faces the carrying surface of the sheet conveying mechanism 1; in the case where both sides have adhesive surfaces, the sheet 100 is placed with the release paper covering one of the adhesive surfaces facing the carrying surface of the sheet conveying mechanism 1.

The sheet conveying mechanism 1 carries the sheet 100 from the side of the sheet 100 where the release paper is covered, and in the case where the carrying surface of the sheet conveying mechanism 1 carrying the sheet 100 is located in the horizontal plane, the release paper is located below the sheet 100, that is, the release paper is pressed by the sheet 100, that is, the paper tearing device is capable of tearing off the release paper covered by the bottom of the sheet 100. It should be noted that, since the lug of the release paper exceeds the edge of the sheet 100 in the horizontal direction, the lug is not pressed between the sheet 100 and the bearing surface, so that when the sheet 100 reaches the paper clamping opening 10, the lug is suspended at the paper clamping opening 10, two clamping portions of the paper tearing chuck 21 are respectively located above and below the lug, then the two clamping portions are close to each other to clamp the lug, and then the release paper can be torn off through displacement of the paper tearing chuck 21 and continuous movement of the sheet 100.

"The paper-tearing chuck 21 can clamp the lug of the release paper covered by the sheet 100 reaching the paper-clamping opening 10 when being positioned at the paper-clamping position" means that the paper-tearing chuck 21 positioned at the paper-clamping position can clamp the lug of the release paper covered by the sheet 100 when the front end of the sheet 100 in the conveying direction moves to the paper-clamping opening 10. The lugs of the release paper are parts beyond the edge of the bonding surface of the sheet 100, and are used for clamping by the paper tearing chuck 21 so as to facilitate the tearing of the release paper. When the paper tearing chuck 21 is located at the paper clamping position, at least part of the paper tearing chuck 21 protrudes upwards through the paper clamping opening 10 to the bearing surface, so that the protruding part can clamp release paper of the sheet 100 borne on the bearing surface, and after clamping, the paper tearing chuck 21 clamps the lugs of the release paper to move to the avoiding position so as to avoid the sheet conveying path, and the sheet 100 can continuously move along the sheet conveying path.

The avoidance position avoids the sheet conveying path, meaning that the avoidance position is not on the sheet conveying path, so that the sheet conveying path can be avoided when the paper tearing chuck 21 is located at the avoidance position, the continuous movement of the sheet 100 is not blocked, and the sheet 100 can continuously move along the sheet conveying path under the conveying of the sheet conveying mechanism 1, that is, the sheet 100 is not stopped in the process of passing through the paper clamping opening 10 and moves all the time. Moreover, the distance between the paper tearing chuck 21 and the sheet 100 is increased in the process of moving the paper tearing chuck 21 towards the avoiding position, so that the speed of tearing off the release paper is increased.

It is understood that arrival of the sheet 100 at the pinch opening 10 means that the leading end of the sheet 100 in the conveying direction moves to the pinch opening. The passage of the sheet 100 through the pinch opening 10 means that the sheet 100 is moving from its leading end to the pinch opening 10 to the trailing end of the sheet 100 about to leave the pinch opening 10.

The sheet conveying mechanism 1 includes, but is not limited to, at least one of a belt conveying mechanism, a chain conveying mechanism, a roller conveying mechanism, a double-speed chain conveying mechanism, and a roller conveying mechanism.

When using this to tear paper device and tear off the type paper, sheet transport mechanism 1 continuously carries sheet 100, when sheet 100 is carried to the time of arriving to press from both sides paper opening 10, tear paper chuck 21 and press from both sides the lug of the type paper of sheet 100, then, tear paper chuck 21 and move to dodging the position through pressing from both sides paper opening 10 under the effect of chuck drive arrangement 22 for tear paper chuck 21 avoid the sheet transport path, in order to allow sheet 100 to continue to follow the sheet transport path and move, moreover, tear paper chuck 21 press from both sides the type paper and remove along the direction that deviates from sheet 100, make from the type paper tear away the bonding face gradually, so, realized tearing to the type paper.

The sheet 100 is continuously moved without being suspended in the whole process, so that the efficiency of the paper tearing process can be improved; in addition, in the process that the release paper is gradually torn off from the bonding surface, the sheet 100 is positioned on the bearing surface of the sheet conveying mechanism 1, so that the falling probability of the sheet 100 can be effectively reduced, the smooth degree of paper tearing operation is improved, and the paper tearing efficiency can be further improved; in addition, the sheet conveying mechanism 1 can convey sheets 100 of different specifications, and when the sheets 100 are placed on the bearing surface of the sheet conveying mechanism 1, the lugs of release papers of the sheets 100 of different specifications are positioned in the same direction of the bearing surface, so that the paper tearing mechanism 2 can clamp the lugs of release papers of the sheets 100 of different sizes, that is, the paper tearing device can be suitable for the sheets 100 of different specifications, and therefore, the paper tearing device has higher compatibility.

In some embodiments of the present application, the paper tearing apparatus further comprises a pressing assembly 3, the pressing assembly 3 being configured to be able to press the sheet of material 100 in a direction towards the carrying surface of the carrier sheet of material 100.

When the front end of the sheet 100 in the conveying direction reaches the paper clamping opening 10, the pressing component 3 presses the sheet 100 towards the bearing surface, so that the probability of overturning the sheet 100 in the process of tearing off release paper can be reduced. It will be appreciated that during the period in which the pressing assembly 3 presses the sheet 100, the sheet 100 is always moved along the sheet conveying path by the sheet conveying mechanism 1. Illustratively, the pressing assembly 3 may actively remove the pressing of the sheet 100 after the release paper is completely torn off the adhesive surface, or may automatically remove the pressing of the sheet 100 after the sheet 100 leaves the pressing assembly 3 with the continuous movement.

Illustratively, the pressing assembly 3 may press the sheet 100 by a cylindrical rolling member, or may press the sheet 100 by a block having a relatively smooth pressing surface, as long as the sheet 100 is pressed, the sheet 100 may still move along the sheet conveying path.

So, through the setting of supporting the pressure subassembly 3, can reduce the sheet 100 and tear paper from the probability that the in-process of type paper takes place to overturn to improve from the smooth degree that type paper was torn, be favorable to improving and tear paper efficiency.

In some embodiments of the present application, the pressing assembly 3 includes a roller 31 and a roller driving device 32, the roller driving device 32 is disposed on the sheet conveying mechanism 1, and an output end of the roller driving device 32 is connected to the roller 31, the roller driving device 32 can drive the roller 31 to approach or separate from the bearing surface, when the sheet 100 reaches the paper clamping opening 10, the roller driving device 32 drives the roller 31 to press against the sheet 100, so that the roller 31 rolls relative to the sheet 100, and the sheet 100 continuously moves along the sheet conveying path.

The roller drive 32 includes, but is not limited to, a linear motor or a linear cylinder.

Therefore, the probability of overturning the sheet 100 in the process of tearing off the release paper can be reduced, and the sheet 100 can continuously move along the sheet conveying path, so that the sheet 100 is not suspended in the conveying process of the sheet conveying mechanism 1, the time for suspension is saved, and the paper tearing efficiency is effectively improved.

In some embodiments of the present application, along the sheet conveying path, the roller 31 is located upstream of the pinch opening 10, and the lug of the release paper covered by the sheet 100 conveyed to the sheet conveying mechanism 1 is disposed toward the downstream end of the sheet conveying path.

The lugs of the release paper covered by the sheet 100 conveyed to the sheet conveying mechanism 1 are disposed toward the downstream end of the sheet conveying path, so that the lugs of the sheet 100 move to the paper clamping opening 10 first, and the paper tearing chuck 21 can smoothly clamp the lugs of the release paper on the sheet 100. The roller 31 is located upstream of the nip opening 10 along the sheet conveying path, that is, the roller 31 is located at a position at the rear of the paper tearing chuck 21 located at the nip position in the conveying direction, and since torque is applied to the sheet 100 to turn the front end of the sheet 100 toward the nip opening 10 when the lug of the sheet 100 reaches the nip opening 10 and the paper tearing chuck 21 pulls the release paper, the application of the pressing force to the position at the rear of the roller 31 to the sheet 100 can reduce the probability of turning the sheet 100, thereby improving the smoothness of release paper tearing.

In some embodiments of the present application, as shown in fig. 2, the sheet conveying mechanism 1 includes a first conveying mechanism 11 and a second conveying mechanism 12 with a downstream end of the first conveying mechanism 11 and an upstream end of the second conveying mechanism 12 being spaced apart to form a pinch opening 10 therebetween, and a conveying path of the first conveying mechanism 11, a conveying path of the second conveying mechanism 12, and a path from the conveying path of the first conveying mechanism 11 to the conveying path of the second conveying mechanism 12 constitute a sheet conveying path of the sheet conveying mechanism 1.

It is understood that the interval between the conveying paths of the first conveying mechanism 11 and the second conveying mechanism 12 is smaller than the dimension of the sheet 100 along the sheet conveying path, that is, the dimension of the sheet 100 along the sheet conveying path is larger than the dimension of the pinch opening 10, so that the sheet 100 does not fall into the pinch opening 10 without being turned over, thereby enabling the sheet 100 to pass smoothly through the pinch opening 10.

The first conveying mechanism 11 and the second conveying mechanism 12 may be any one of a belt conveying mechanism, a chain conveying mechanism, a roller conveying mechanism, a double-speed chain conveying mechanism, and a roller conveying mechanism. Illustratively, the first conveying mechanism 11 and the second conveying mechanism 12 are both belt conveying mechanisms, the upper surface of the belt conveying mechanism is the bearing surface of the sheet conveying mechanism 1, and the sheet 100 is placed on the upper surface of the belt and moves synchronously with the transmission of the belt under the action of friction force of the belt.

In this way, the paper tearing chuck 21 is made to pull the release paper in the direction perpendicular to the sheet 100, and the paper tearing effect can be improved.

Illustratively, the in-place detecting device includes a proximity sensor 41, and the proximity sensor 41 determines whether or not the sheet 100 reaches the pinch opening 10 by detecting whether or not the sheet 100 is present within a set distance range.

Illustratively, the in-place detection means comprises an encoder 42 and a proximity sensor 41. When the detection results of the encoder 42 and the proximity sensor 41 are the same, the accuracy of the detection results is high, the actions of pressing the sheet 100 and clamping the release paper can be performed subsequently, and when one of the two detects the sheet 100 and the other does not detect the sheet 100, the fault of the two is indicated, and if the detection results are not accurate enough, an alarm signal is sent to prompt a serviceman to perform maintenance, and the subsequent actions of pressing or clamping are not performed.

The present application is not particularly limited as long as it is suitably applied to the paper tearing device, and the encoder 42 and the proximity sensor 41 may be self-made or commercially available products may be purchased.
