[0030] like Figures 1 to 7 As shown, the utility model is a sealing strip trimming machine, comprising: a machine platform 1, a mounting frame 2 fixedly mounted on the top of the machine platform 1, a conveying mechanism for conveying the sealing strip, a limiting mechanism for limiting the position of the sealing strip during the conveying process, and a cutting mechanism for cutting the sealing strip;

[0031] The conveying mechanism includes: a conveyor belt 3 installed on the side wall of the mounting frame 2, a limiting roller 18 rotatably installed on the side wall of the mounting frame 2, a driving component for driving the limiting roller 18 to rotate, a linkage roller 17 arranged on the top of the limiting roller 18, and an adjusting component for adjusting the height of the linkage roller 17;

[0032] When the sealing strip is transported, the conveyor belt 3 is started. Through the rotation of the conveyor belt 3, the sealing strip can be transported to the cutting mechanism, and the sealing strip passes between the interlocking roller 17 and the limiting roller 18. At this time, the interlocking roller 17 is moved downward by the adjusting component, and the adjusting component includes: a threaded rod 13 threadedly connected to the side wall of the mounting frame 2, a rotating plate 14 fixedly mounted on the top of the threaded rod 13, and an interlocking plate 16 rotatably mounted on the bottom end of the rotating plate 14; the interlocking roller 17 is rotatably mounted on the side wall of the interlocking plate 16, and a limiting groove is provided on the side wall of the mounting frame 2. 6 is slidably installed in the inner cavity of the limiting groove; that is, by rotating the rotating plate 14, the rotating plate 14 drives the threaded rod 13 to rotate, and the threaded rod 13 can drive the linkage plate 16 to move downward, and drive the linkage spring 15 to stretch, and the linkage plate 16 moves downward, and the linkage roller 17 can be driven to move downward, so that the distance between the linkage roller 17 and the limiting roller 18 can be adjusted according to the thickness of the sealing strip, so that the linkage roller 17 and the limiting roller 18 are both in contact with the sealing strip, so that the sealing strip can be clamped after the linkage roller 17 and the limiting roller 18 abut against the sealing strip;

[0033] At this time, the driving assembly is started, and the driving assembly includes: a motor 19 fixedly mounted on the inner wall of the machine 1, a driving gear 20 fixedly mounted on one end of the output shaft of the motor 19, a driven gear 22 fixedly mounted on one end of the limiting roller 18, and a synchronous belt 21 meshing with the outer edges of the driving gear 20 and the driven gear 22; by starting the motor 19, the driving gear 20 can be driven to rotate, the driving gear 20 can drive the synchronous belt 21 to rotate, the synchronous belt 21 can drive the driven gear 22 to rotate, and the driven gear 22 can drive the limiting roller 18 to rotate, so that the sealing strip can be driven to move, thereby realizing the conveying of the sealing strip.

[0034] By setting up the conveying mechanism, on the one hand, the distance between the interlocking roller 17 and the limiting roller 18 can be adjusted according to the thickness of the sealing strip, so as to facilitate the conveying of sealing strips of different thicknesses and improve the applicability of the device. On the other hand, sealing strips of different thicknesses can be clamped and then conveyed, which avoids the deviation of the sealing strips during conveyance and plays a role in limiting the conveyance of the sealing strips.

[0035] The limiting mechanism includes: a limiting component 1 for longitudinally limiting the sealing strip, a limiting component 2 for lateral limiting the sealing strip, and an extrusion component for squeezing and fixing the sealing strip during cutting. The limiting component 1 includes: a slide groove opened on the side wall of the mounting frame 2, a rotating rod slidably installed in the inner cavity of the slide groove, and a pressure roller 4 fixedly sleeved on the outer edge of the rotating rod.

[0036] The slide groove in the present application is opened along the height direction of the mounting frame 2, so the rotating rod can move up and down in the inner cavity of the slide groove. During the conveying process of the sealing strip, several pressure rollers 4 are pressed on the top of the sealing strip. Through the gravity of the pressure rollers 4, the sealing strip can be pressed tightly on the top of the conveyor belt 3, avoiding the sealing strip from deviating on the top of the conveyor belt 3, thereby realizing the longitudinal limitation of the sealing strip, so that the conveyor belt 3 can better convey the sealing strip.

[0037] The second limiting component group includes: a slide bar 1 5 and a slide bar 2 8 fixedly mounted on the side wall of the mounting frame 2, a limiting plate 1 6 sliding along the axial direction of the slide bar 1 5, a bolt 1 7 fixing the limiting plate 1 6, a limiting plate 2 9 sliding along the axial direction of the slide bar 2 8, and a bolt 2 10 fixing the limiting plate 2 9;

[0038] The sealing strip passes through the bottom of the slide bar 15 and the slide bar 28, and enters between the linkage roller 17 and the limiting roller 18. At this time, the distance between adjacent limiting plates 6 can be adjusted according to the width of the sealing strip, and the limiting plates 6 can be fixed by tightening the bolts 7, so that the adjusted distance between adjacent limiting plates 6 is always maintained. At the same time, the distance between adjacent limiting plates 9 can be adjusted according to the width of the sealing strip, and the limiting plates 9 can be fixed by tightening the bolts 10, so that the adjusted distance between adjacent bolts 10 is always maintained. Through the setting of the limiting plates 6 and the bolts 10, the sealing strip can be prevented from deviating at the bottom of the slide bars 15 and the slide bars 28 during transportation, thereby realizing the lateral limitation of the sealing strip.

[0039] Since the distance between adjacent limiting plates 1 6 and the distance between adjacent limiting plates 2 9 can be freely adjusted, the applicability of the device is improved.

[0040] In addition, there are multiple limit plates 1 6 and 2 9, so that multiple sealing strips can be limited at the same time, so that the device can convey multiple sealing strips at the same time, realize the cutting of multiple sealing strips at the same time, and improve work efficiency.

[0041] The extrusion assembly includes: a pressing plate 23 for squeezing and fixing the sealing strip, and a cylinder 11 for driving the pressing plate 23 to move; when the sealing strip is conveyed to a certain length, the conveying mechanism stops running, and at this time, the cylinder 11 is started to drive the pressing plate 23 to move downward, and the sealing strip can be squeezed and fixed through the mutual cooperation between the pressing plate 23 and the mounting frame 2, thereby preventing the sealing strip from shifting during the cutting process, thereby improving the cutting accuracy;

[0042] By setting the limiting mechanism, on the one hand, the sealing strip can be limited during the conveying process, thereby avoiding the displacement of the sealing strip during the conveying process and improving the conveying accuracy. On the other hand, the sealing strip can be limited and fixed during cutting, thereby preventing the sealing strip from shifting during the cutting process and improving the cutting accuracy.

[0043] The cutting mechanism includes: a cutter 24 for cutting the sealing strip, and a cylinder 12 for driving the cutter 24 to move; when the sealing strip is squeezed and fixed, the cylinder 12 is started to drive the cutter 24 to move downward, so that the sealing strip can be cut without manual operation, thereby improving work efficiency.

[0044] Working principle: When in use, the sealing strip is conveyed to the cutting mechanism through the conveying mechanism. During the conveying process, the limiting mechanism can be set to limit the sealing strip during the conveying process, thereby avoiding the displacement of the sealing strip during the conveying process and improving the accuracy of the conveying. On the other hand, the sealing strip can be limited and fixed during cutting, thereby preventing the sealing strip from shifting during the cutting process and improving the cutting accuracy.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
