Description

Technical Field

[0001] This invention relates to the field of film slitting technology, and more specifically to a fully automatic high-speed slitting machine. Background Technology

[0002] A slitting machine typically consists of components such as an unwinding mechanism, a traction mechanism, a cutting mechanism, and a rewinding mechanism. It is a mechanical device that uses blades to longitudinally cut wide sheets of paper, mica tape, or film of a certain width into multiple narrow strips of material.

[0003] When a slitting machine cuts flexible objects, such as paper or film, the cutting blade causes the object to deform at the cutting position, resulting in defects at the cutting position and affecting the cutting quality. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fully automatic high-speed slitting machine, which can effectively solve the problem that when the existing slitting machine cuts flexible objects, such as paper or film, the cutting blade causes certain deformation of the object at the cutting position, resulting in defects at the cutting position and affecting the cutting quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a fully automatic high-speed slitting machine, including an overlapping member with two bladders mounted on both sides of its top surface, and a cutting element on one side of the overlapping member for cutting the object to be slitted; it also includes a rotating roller rotatably connected to the overlapping member for conveying the object to be slitted, the rotating roller having two symmetrically shaped cavities in its middle section, with multiple annular components slidably connected within each cavity, and two symmetrically shaped rings fixedly connected to the middle of the outer wall of the rotating roller, with cutting grooves formed in the middle of the two rings on the outer wall of the rotating roller, and the two cavities communicating with the bladders via connecting pipes; it also includes a driving mechanism for driving the rotating roller to rotate, including connection with external... The motor output shaft is fixedly connected to the drive shaft. The inner end of the drive shaft is sequentially fixedly installed with a cam and a drive gear. The drive gear meshes with the driven gear fixedly installed at the end of the rotating roller. It also includes a flattening mechanism for flattening the cutting position of the object to be cut after shearing. It includes a movable part that is movably connected relative to the overlapping part. Movable parts are respectively provided on both sides of the movable part. The two movable parts are elastically connected in the horizontal direction by an elastic element. The lower end of the movable part is movably connected to a pressure roller. A piston tube communicating with the bladder is fixedly connected inside the movable part. A piston rod is movably connected inside the piston tube. The lower end of the piston rod is fixedly connected to an overlapping plate. The two ends of the overlapping plate are slidably engaged with the limiting grooves opened on the top surface of the movable part.

[0007] Furthermore, the outer wall of the cam slides in conjunction with the outer wall of the bladder; when the external motor drives the cam to rotate, it will squeeze the bladder set on the overlapping part, causing the annular part movably connected to the rotating roller to move outward along the radial direction of the rotating roller and come into contact with the object to be cut wound on the rotating roller.

[0008] Furthermore, the limiting frame is distributed on both sides of the moving part in a symmetrical structure and is fixedly connected to the overlapping part; a sliding groove is provided on the inner side of the limiting frame, and a first electromagnet is fixedly installed at the bottom of the sliding groove; the outer wall of the moving part slides in conjunction with the inner wall of the sliding groove.

[0009] Furthermore, the lower end of the movable component has two inclined surfaces in a symmetrical structure; when the two movable components move downward, their lower outer walls will contact the inclined surfaces and move away from each other; a second electromagnet is installed on the bottom surface of the movable component at the position corresponding to the first electromagnet.

[0010] Furthermore, a pressure switch is installed on the inner wall of the limiting groove; when the two movable parts move downward to the lowest position of the inclined plane, the outer wall of the overlapping plate contacts the pressure switch and connects the external power supply of the first electromagnet and the second electromagnet, so that the first electromagnet and the second electromagnet are magnetically attracted.

[0011] Furthermore, the end of the pressure roller is rotatably connected to a connecting shaft; the connecting shaft is slidably engaged with a vertical groove formed on the movable part; and the connecting shaft is connected and fixed to the upper inner wall of the vertical groove through an elastic element.

[0012] Furthermore, a square groove is provided on the bottom surface of the moving part; through holes are uniformly provided in the middle of the upper inner wall of the square groove; the through holes are connected to the output end of the external hot air pump.

[0013] Furthermore, the separator is rotatably connected to the overlapping member; a circular protrusion is fixedly installed in the middle of the separator for separating the cut objects after slitting. Beneficial effects

[0014] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0015] The present invention, through the setting of a rotating roller and a ring fixedly connected to the middle of the rotating roller, and in conjunction with multiple ring parts movably connected inside the rotating roller, can ensure the cutting effect of the cutting blade; at the same time, the setting of a flattening mechanism can realize the flattening of the cutting position and ensure the slitting effect.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to embodiments. Example

[0034] See attached document Figure 1 -Appendix Figure 10 As shown, the fully automatic high-speed slitting machine includes an overlap member 100, with two bladders 110 mounted on both sides of the top surface of the overlap member 100. A cutting element 120 is also provided on one side of the overlap member 100 for cutting the object to be slitted. It also includes a rotating roller 200, which is rotatably connected to the overlap member 100 for conveying the object to be slitted. It is worth noting that the cutting element 120 can move toward one side of the overlap member 100 under the drive of an external hydraulic cylinder and cut the object to be slitted that passes over the rotating roller 200.

[0035] Specifically, the slitting machine also includes a drive mechanism for driving the rotating roller 200 to rotate. This mechanism includes a drive shaft 300 fixedly connected to the output shaft of an external motor. A cam 310 and a drive gear 320 are sequentially fixedly installed on the inner end of the drive shaft 300. The drive gear 320 meshes with a driven gear 230 fixedly installed at the end of the rotating roller 200. When the external motor drives the cam 310 to rotate, it will squeeze the bladder 110 set on the overlapping member 100. When the external motor drives the drive shaft 300 to rotate, combined with the meshing relationship between the drive gear 320 and the driven gear 230, it will drive the rotating roller 200 to rotate, thereby conveying the object to be slitting. At the same time, since the drive shaft 300 is also fixedly connected to the cam 310, the cam 310 will also rotate as the drive shaft 300 rotates.

[0036] Specifically, the rotating roller 200 has two symmetrical cavities 201 in its middle section. Multiple annular components 220 are slidably connected within each cavity 201 in a ring-like structure. Two circular rings 210 are fixedly connected symmetrically to the middle of the outer wall of the rotating roller 200. A cutting groove 202 is formed in the middle of the two circular rings 210 on the outer wall of the rotating roller 200. The two cavities 201 are connected to the capsule 110 via connecting pipes 240. The outer wall of the cam 310 slides against the outer wall of the capsule 110. When an external motor drives the cam 310 to rotate, it compresses the capsule 110 mounted on the connecting member 100. The connection between the capsule 110 and the cavity 201 within the rotating roller 200 via the connecting pipes 240 allows for the compression of the capsule. The annular member 220, which is movably connected to the rotating roller 200, moves outward along the radial direction of the rotating roller 200 and contacts the object to be cut that is wound on the rotating roller 200. It is worth noting that when the rotating roller 200 is cutting the object to be cut, the multiple annular members 220 movably connected to the rotating roller 200 will intermittently expand outward, and the circular outline formed by the multiple annular members 220 will be larger than the diameter of the circular ring 210. During this process, the cutting member 120 keeps rotating and cutting the object to be cut. During this process, the object to be cut will intermittently change its contact with the circular ring 210 or the annular member 220, but it can always ensure that the object to be cut at the cutting groove 202 position is in a taut state for better cutting.

[0037] It is worth noting that the significance of the multiple ring-shaped components 220 that constantly change position is that they prevent the object to be cut at the cutting groove 202 from being in a loose state for a period of time due to the setting of the ring 210. Specifically, since the diameter of the ring 210 is larger than the diameter of the rotating roller 200, when the multiple ring-shaped components 220 are in the cavity 201, the object to be cut only contacts the outer wall of the ring 210, making the object to be cut at the cutting groove 202 in a taut state. However, as the object to be cut continues to rotate with the rotating roller 200, the object to be cut at the cutting groove 202 tends to sink into the cutting groove 202. To solve this problem, during the cutting process, the ring-shaped components 220 will intermittently expand outward to support the object to be cut, so that the object to be cut at the cutting groove 202 position is reorganized to ensure that it is always in a taut state and to ensure the cutting effect.

[0038] In particular, in order to ensure the flatness of the cut surface after cutting, a flattening mechanism is also provided in this case to flatten the cutting position of the object to be cut after shearing. It includes a movable part 400 that is movably connected to the overlapping part 100. Movable parts 500 are respectively provided on both sides of the movable part 400. A pressure roller 510 is movably connected to the lower end of the movable part 500. A piston tube 420 communicating with the bladder 110 is fixedly connected inside the movable part 400. A piston rod 421 is movably connected inside the piston tube 420. An overlapping plate 422 is fixedly connected to the lower end of the piston rod 421. The two ends of the overlapping plate 422 are slidably engaged with the limiting groove 501 opened on the top surface of the movable part 500. The lower end of the movable member 400 has two inclined surfaces 401 arranged in a symmetrical structure. When the two movable members 500 move downward, their lower outer walls will contact the inclined surfaces 401 and move away from each other. The end of the pressure roller 510 is rotatably connected to a connecting shaft. The connecting shaft is slidably engaged with the vertical groove 502 opened on the movable member 500. The connecting shaft is also connected and fixed to the upper inner wall of the vertical groove 502 through an elastic element. It is worth noting that when the slitting machine is in use, the set bladder 110 will be intermittently squeezed. Combined with the communication between the set bladder 110 and the piston tube 420, the piston rod 421 movably connected in the piston tube 420 will intermittently move downward. When the 21 moves downward, the overlapping plate 422, which is fixed to it, will move downward synchronously, and drive the movable parts 500 located on both sides of the movable part 400 to move downward. When it moves to the lowest position, the pressure roller 510 contacts the object to be cut and squeezes it. When it continues to move downward, the lower outer wall of the movable part 500 will contact the inclined surface 401 opened on the movable part 400, and cause the two movable parts 500 to move away from each other. It is worth noting that at this time, combined with the contact between the outer wall of the pressure roller 510 and the object to be cut, it will drive the object to be cut to move to both sides around the cutting position to separate it, making up for the part of the object to be cut that is not completely cut.

[0039] In this case, a limiting frame 140 is also provided, which is symmetrically distributed on both sides of the movable part 400 and is fixedly connected to the overlapping part 100. A sliding groove 141 is provided on the inner side of the limiting frame 140, and a first electromagnet 142 is fixedly installed at the bottom of the sliding groove 141. The outer wall of the movable part 400 slides in conjunction with the inner wall of the sliding groove 141. A second electromagnet 410 is installed at the bottom surface of the movable part 400 corresponding to the position of the first electromagnet 142. A pressure switch is provided on the inner wall of the limiting groove 501. When the two movable parts 500 move downward to the lowest position of the inclined surface 401, the outer wall of the overlapping plate 422 contacts the pressure switch and connects the external power supply of the first electromagnet 142 and the second electromagnet 410, so that the first electromagnet 142 and the second electromagnet 410 are magnetically attracted.

[0040] When the two movable parts 500 move away from each other, the overlapping plate 422 slides within the limiting groove 501. After sliding relative to each other for a certain distance, the pressure switch connects the first electromagnet 142 and the second electromagnet 410 to the external power supply, causing them to attract each other. At this time, the movable part 400 slides within the sliding groove 141, causing the lower end of the movable part 400, which was not originally in contact with the object to be cut, to contact the object to be cut. A square groove 402 is provided on the bottom surface of the movable part 400; through holes 403 are evenly distributed in the middle of the upper inner wall of the square groove 402; the through holes 403 and... The output end of the external hot air pump remains connected. When the lower end of the moving part 400 contacts the object to be cut, the square groove 402 on the bottom surface of the moving part 400 forms a sealed space with the object to be cut. Combined with the connection between the through holes 403 uniformly opened in the square groove 402 and the external hot air pump, the cutting position of the object to be cut is heat-treated to ensure the flatness of the cutting end face. The end face treatment effect is more obvious when the object to be cut is a film product. When the cam 310 does not compress the bladder 110, the movable part 500 is reset, and the two movable parts 500 are reset by the elastic part set in the middle of them.

[0041] In order to ensure the slitting effect, this case also includes a separator 130, which is rotatably connected to the overlapping member 100; a circular protrusion 131 is fixedly installed in the middle of the separator 130, which is used to separate the cut object after slitting. The circular protrusion 131 is inserted into the cutting position in the middle of the cut object to separate the two parts formed by the cut object and ensure the slitting effect.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
