Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of the utility model with the paper cutter of blade protective device 4 is described further.
A kind of paper cutter with blade protective device, comprise paper feed track 1, cutting knife 2 and 3, cutter, tool rest 3 is arranged on the top of paper feed track 1, cutting knife 2 is arranged on tool rest 3, position corresponding with cutting knife 2 on paper feed track 1 is provided with the blade protective device 4 coordinated with cutting knife 2, blade protective device 4 comprises cavity 48 and several cylinders 41, cylinder 41 is all arranged on the sidewall of cavity 48 both sides, the sidewall of cylinder 41 can be conflicted with the side of cutting knife 2, by arranging the cavity 48 coordinated with it above cutting knife 2, and several cylinders 41 can conflicted with cutting knife 2 side are set on the both sides sidewall of cavity 48, make cutting knife 2 when there is " cutting sky cutter " phenomenon, cavity 48 can be entered, and the speed of cutting knife 2 feed is slowed down by the force of rolling friction between cylinder 41 and cutting knife 2, can either prevent blade pressurized from turned phenomenon occurring, again because there is no relative displacement between cutting knife 2 and cylinder 41 when there is rolling friction, thus the wearing and tearing of knife edge part can also be reduced, rotating shaft 45 is provided with in cylinder 41, rotating shaft 45 is connected with blade protective device 4 slippage, and the chute 43 of cylinder 41 on blade protective device 4 is perpendicular to cavity 48 sidewall, elastic component cylinder 41 being pushed cavity 48 is also provided with in blade protective device 4, roller is set like this and can either ensures that roller can cover when cutting knife 2 feed in cutting knife 2 side, thus obtain larger force of rolling friction, when also prevent cutting knife 2 feed, side is subject to the excessive hard breakdown to cutting knife 2 that may cause of cylinder 41 applied pressure simultaneously, in order to obtain optimum rolling friction effect, here elastic component is comprise the spring 44 perpendicular to cavity 48 sidewall, and spring 44 has specified maximum elastic force, cylinder 41 arranges the spring 44 with specified maximum elastic force and can ensure that cylinder 41 can apply enough pressure to cutting knife 2, thus the force of rolling friction required for obtaining, cylinder 41 is rotated by the rotating shaft 45 be arranged on wherein, in order to mention the slowing effect of cylinder 41 pairs of cutting knifes 2, need to arrange rotating shaft damping unit 46 in rotating shaft 45, the rotating speed of cylinder 41 is reduced by arranging rotating shaft damping unit 46, thus realize slowing down the technical requirement that cutting knife 2 enters speed, here rotating shaft damping unit 46 can select air damping pad, air damping cushion cover is located in rotating shaft 45, and the sidewall interference fit of air damping pad and chute 43.
In order to protect cutting knife 2 further, reduce the frictional dissipation suffered by cutting knife 2 and hard breakdown to greatest extent, also need on the outer wall of cylinder 41, be provided with the harder elastic layer of quality, why select the harder elastic layer of quality be in order to prevent elastic layer in the feed process of cutting knife 2 cut by the blade of cutting knife 2, contribute to the service life of improving elastic layer, here elastic layer comprises oak layer 42, oak is a kind of hardwood, quality is very hard, and it is very wear-resisting, and oak itself still has good elasticity as a kind of wood materials, here by the effect that oak can realize required for us as the raw material of elastic layer.
When the feed velocity of cutting knife 2 is too fast, only apply force of rolling friction by cylinder 41 pairs of cutting knifes 2 still inadequate to some extent to the feed velocity slowing down cutting knife 2, also need in cavity 48, to add Friction speed-reducing device to slow down the feed velocity of cutting knife 2, here on the inwall of cavity 48, the part of bottom is provided with the blocking elements stoping the blade of cutting knife 2 to be conflicted at cavity 48 top, when cutting knife 2 is close to cavity 48 top, when being about to occur in cavity 48 top to conflict, here the blocking elements arranged can stop the tip contact of cutting knife 2 blade to cavity 48 top, thus prevent blade top from sustaining damage, blocking elements comprises two pieces of symmetrically arranged ABS block rubbers 47, ABS block rubber 47 can have the blade sides of cutting knife 2 to conflict, ABS rubber has higher structural strength and larger frictional force, effectively can either stop the feed of cutting knife 2, to be not easy damage by cutting knife 2, service life is longer.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
