Abstract
The utility model discloses a cutting tool for medical films. The cutting tool for the medical films comprises a cutter and a base plate. The cutter comprises a support and a roller, wherein the support can be held in hand; the roller is arranged on the support and is provided with a cutting edge; the base plate is provided with a rectangular through hole; the width of the roller is the width of the through hole at most; the roller is movably connected with the base plate through being inserted into the through hole; the radius of the roller is greater than the thickness of the base plate; two rolling shafts which protrude outwards to form a cylinder shape respectively and play a supporting role are arranged on the roller in the direction of axis of rotation; and the width between the rolling shafts is equal to that of the through hole. According to the cutting tool for the medical films, the movement locus of the cutter is limited through the base plate to realize the linear cutting movement of the cutter, and therefore, the films which are regular in edge and appearance can be produced. Therefore, the medical films produced in such a way are higher in appearance quality.
Description
Technical field
The utility model relates to a kind of medical film cutting tool.
Background technology
Manually cut the mode that medical film generally all passes through blade cuts or scissors cutting in the prior art, not only waste time and energy, and film out-of-shape, the edge out-of-flatness of cutting gained.This is because the trend of blade is fully by human perception during blade cuts, and manually-operated accuracy is limited, so cause cutting gained film out-of-shape.And when utilizing the scissors cutting, blade is in up and down both sides extruding of film, so that therefore film cutting edge stress deformation causes the irregular phenomenon in edge.The cutting effect of medical film is bad not only to affect product quality, and is not easy to use and deposit.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of can to cut out the edge smooth, the medical film cutting tool of the film of regular shape.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this medical film cutting tool comprises cutter and backing plate, described cutter comprises the support that can hand and is arranged on the roller with blade on the support, described backing plate is provided with rectangular through-hole, described roller widths is at most the through hole width, described roller is flexibly connected with backing plate by inserting in the through hole, described roller radius is greater than plate thickness, described roller is provided with two outwards cylindrical passive roller bearings of projection in the shaft axis direction, and the width between the described roller bearing is identical with the through hole width.Cutter moves in the through hole of backing plate, owing to be subject to the restriction of backing plate, so that cutter can only move along through hole under external force, so cutter is done rectilinear motion.Overcome the direction control problem of blade cuts in the conventional art, Here it is so that cutting gained medical film neat in edge and whole film regular shape.Roller bearing is embedded in through hole when work at cutter can provide support force from backing plate for cutter, and then keeps the constant pressure between cutter and the film, and this can prevent that film is stressed excessive and be out of shape.
The utility model adopts technique scheme: the medical film cutting tool limits cutting tool path by backing plate, realizes the straight cuts motion of cutter, can produce thus the film of neat in edge, profile rule.Therefore, the medical film of producing like this gained has preferably profile quality.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
Fig. 1 is the structural representation of the cutter of a kind of medical film cutting tool of the utility model;
Fig. 2 is the structural representation of the backing plate of a kind of medical film cutting tool of the utility model;
Fig. 3 is the use schematic diagram of a kind of medical film cutting tool of the utility model.
The specific embodiment
As shown in Figure 1, 2, 3, this medical film cutting tool comprises two parts, is respectively cutter and backing plate 7.Cutter comprises for hand-held support 2 with for the roller 3 that cuts medical film.Support 2 is Y-shaped, is provided with long handle section 4 and furcation 5.Long handle section 4 is cylindrical-shaped structure, and furcation 5 is positioned at an end of long handle section 4.Furcation 5 is concave structure, and it is used for fixed idler whell 3.The A/F of furcation 5 is larger than the width of roller 3, and the radius of the opening depth ratio roller 3 of furcation 5 is large.Roller 3 is in the form of annular discs, and the edge is sharp blade, and its thickness reduces on the extrorse direction in centre gradually.Roller 3 both sides are provided with the cylindrical roller bearing 6 of outside projection in rotor shaft direction, and roller bearing 6 is in the same center line with roller 3, and the radius of roller 3 is greater than the radius of roller bearing 6.The width of roller 3 is the A/F that the width between two roller bearing 6 outer surveys is less than furcation 5.The end of furcation 5 is provided with two big or small identical circular holes that are in the same center line, and the going out of roller bearing 6 is provided with cylindrical protuberance that should circular hole.Roller 3 be installed in the furcation 5 of support 2 when interior protuberance be embedded in the circular hole, thus so that roller 3 be flexibly connected with support 2.After the installation, roller bearing 6 protrudes in the outside of furcation 5, and the blade of roller 3 is in the position relationship that separates with furcation 5.Backing plate 7 is the tabular rectangular structure, and the centre is provided with a rectangular through-hole 1, and through hole 1 runs through backing plate 7.Width between two roller bearings 6 on the width of through hole 1 and the roller 3 is identical, and also the Breadth Maximum with roller 3 is identical.
As shown in Figure 3, backing plate 7 is pressed on the medical film that needs cutting during use, and this end that cutter is provided with roller 3 is embedded in the through hole 1.This moment, roller bearing 6 was pressed on the backing plate 7, and roller 3 passes the opposite side that through hole 1 and blade are positioned at backing plate 7.Because the width of roller 3 the widest part is identical with through hole 1 width, and the width between two roller bearings 6 is also identical with through hole 1 width, therefore roller 3 is embedded in the restriction that is subject to through hole 1 behind the through hole 1, so that roller 3 can only move along the direction of through hole 1, roller 3 is just done rectilinear motion like this.Under roller bearing 6 supporting roles, the length that roller 3 stretches in through hole 1 is fixed, so the distance that roller 3 blades protrude at backing plate 7 just is fixed, roller 3 when the cutting medical film to the constant pressure of film.The medical film cutting tool is realized the straight cuts motion of cutter by backing plate 7 restriction cutting tool paths, can produce thus the film of neat in edge, profile rule.
