[0033] Example 1

[0034] See also Figure 1-8 The present invention provides an embodiment: an equidistant cutting device for PVC sealant processing with adjustable spacing, comprising a feeding device 3 for support, and both sides of the upper end surface of the feeding device 3 are provided with limiting side plates 9 for limiting, and the inner end surface of the limiting side plate 9 is provided with a fixed slide groove 1 near the bottom, and the inner end surface of the fixed slide groove 1 is provided with a supporting slide shaft 4 for guiding, and the upper end surfaces of the two sets of limiting side plates 9 are provided with supporting top plates 8,

[0037] The inner end surface of the limiting side plate 9 drives the cutting device 2 to move up and down inside the fixed slide groove 1 through the transmission device 5 cyclically.

[0038] The cutting device 2 includes a guide slide 21, a servo motor 27 for transmission is arranged at the center of the rear end surface of the guide slide 21, a ball screw 23 is fixedly arranged at the output end of the servo motor 27, and three groups of guide slide shafts 22 are equidistantly arranged on the inner end surface of the guide slide 21, and three groups of ball slides 24 are equidistantly threadedly connected to the inner end surface of the guide slide 21 through the ball screw 23, a cutting tool 26 is arranged at the center of the lower end surface of the ball slide 24, fixed slides 28 are arranged on both side surfaces of the guide slide 21, and a return spring 25 is fixedly arranged at the center of the lower end surface of the fixed slide 28.

[0039] The feeding device 3 includes a supporting slide 33 for guiding, and three groups of material guide grooves 35 are equidistantly provided on the inner end surface of the supporting slide 33, and material guide inclined plates 34 are provided at the tail end of the supporting slide 33 opposite to the three groups of material guide grooves 35. Two groups of material guide rollers 38 are rotatably clamped at the front of the supporting slide 33, and transmission gears 31 are provided on the side end surfaces of the two groups of material guide rollers 38. A reduction motor 37 is provided on the side end surface of the supporting slide 33 opposite to the upper material guide roller 38, a fixed clamping seat 32 is provided on the upper end surface of the supporting slide 33 near the material guide roller 38, and three groups of pressing rollers 36 are rotatably clamped on the inner end surface of the fixed clamping seat 32 at equal intervals.

[0040] The transmission device 5 comprises a transmission clamping shaft 53 , a driven bevel gear 51 is arranged near the middle of the outer end surface of the transmission clamping shaft 53 , and cam pressure plates 52 are arranged near both ends of the outer end surface of the transmission clamping shaft 53 .

[0041] The active bevel gear 7 is meshedly connected with the driven bevel gear 51 , and the bottom of the limiting clamping seat 10 is fittedly connected with the upper end surface of the driven bevel gear 51 , which can effectively improve the subsequent transmission stability of the driven bevel gear 51 .

[0042] The fixed slide 28 is adapted to the fixed slide groove 1, and the cutting device 2 is adapted to the fixed slide groove 1 through the fixed slide 28 and then slidably engaged with the outer end surface of the supporting slide shaft 4, and the lower end surface of the return spring 25 is fixedly connected to the bottom of the fixed slide groove 1. The two sets of return springs 25 can provide sufficient elastic force for the subsequent guide slide 21 to fit the bottom of the cam pressure plate 52, and can also improve the stability of the subsequent guide slide 21 lifting and resetting.

[0043] The width of the cutting tool 26 is equal to the width of the material guide chute 35, and when the guide slide 21 slides to the bottom, the lower end surface of the cutting tool 26 is fitted and connected with the upper end surface of the material guide chute 35. When the guide slide 21 slides to the bottom, the cutting tool 26 can be positioned at the bottom of the material guide chute 35, thereby improving the stability of the sealant cutting.

[0044] The two sets of guide rollers 38 are meshed and connected through the transmission gear 31, and the lower end surface of the cam pressure plate 52 is elastically fitted and connected with the upper end surface of the guide slide 21. The cam pressure plate 52 is cam-shaped, so that the cam pressure plate 52 can cyclically drive the guide slide 21 to move up and down inside the limiting side plate 9, thereby facilitating the subsequent cutting of the PVC sealant.

[0045] Working principle: Before use, the user can guide the sealant to be cut at equal intervals into the interior of the multiple groups of guide rollers 38, and then start the reduction motor 37 and the servo motor 6 through the external control device. At this time, the reduction motor 37 can drive the internal guide roller 38 to rotate, and at the same time, the side of the guide roller 38 is meshed and connected through two groups of mutually meshing transmission gears 31, so that the two groups of guide rollers 38 can be meshed in the opposite direction synchronously, thereby driving the internal sealant to circulate and be introduced into the guide chute 35. At this time, the multiple groups of pressing rollers 36 inside the fixed card seat 32 can perform a full-scale pressing operation on the multiple groups of sealants in the guide chute 35, thereby improving the stability of the sealant conveying inside the guide chute 35. When the sealant is introduced to the bottom of the cutting device 2 under the conveyance of the guide roller 38, the servo motor 6 can drive the active bevel gear 7 at the bottom to rotate. At the same time, when the active bevel gear 7 is rotated, the servo motor 6 can rotate the active bevel gear 7. When rotating, the active bevel gear 7 can be meshed with the driven bevel gear 51, thereby synchronously driving the transmission card shaft 53 and the two groups of cam pressure plates 52 to rotate synchronously. At this time, the two groups of cam pressure plates 52 can be elastically pressed with the guide slide 21, thereby driving the guide slide 21 to move from top to bottom, thereby driving the three groups of cutting tools 26 to quickly and equidistantly cut the sealant inside the guide slide 35. The cut sealant is squeezed by the latter group of sealant and then exported through the guide inclined plate 34. When adjusting the length of the cut sealant, the staff can start the servo motor 27 at different locations. At this time, the servo motor 27 can drive the corresponding ball screw 23 to rotate, and then through the threaded connection between the ball screw 23 and the ball slide 24, the position of the cutting tool 26 at the bottom of the guide slide 21 is adjusted, thereby cooperating with the transmission of the reduction motor 37, and then equidistantly cutting sealants of different lengths.
