Description

One kind cutting horsehair haircut actuating unit

Technical field

The utility model belongs to the improvement of electronic cropping tool construction, especially one kind and cuts horsehair haircut power transmission dress It sets.

Background technique

At present, it is common to use driven shearing horsehair shearing machine, provide power series excited machine since revolving speed is excessively high, need big Width reduces input speed and can just obtain suitably exporting revolving speed, this, which allows for power transmission deceleration device, must reach two-stage or two Grade or more The gear deceleration can just obtain suitably exporting revolving speed, this makes to cut horsehair shearing machine, and structure is complicated, especially in the presence of nothing Method isolation dust and hair stubble enter the technical disadvantages such as motor inside.

Utility model content

The purpose of this utility model is to provide one kind to cut horsehair haircut actuating unit, uses low pressure brushless dc Motivation provides power；Power transmission deceleration device is that primary speed-down gear can reach suitable output revolving speed, and shearing machine is whole Structure is simple, slim profile, light-weight；Completely cut off dust using unique electric machine external fan technology and hair stubble enters in motor Portion, to improve the service life of motor；Unique ventilating system makes also cool down blade while ventilated cooling motor.

Purpose of the utility model is realized as follows: one kind cuts horsehair haircut actuating unit, including front end is equipped with There is the handpiece body for cutting horsehair haircut, cuts horsehair cutter head and be made of ledger-plate and cutting blade, ledger-plate and cutting blade are respectively self-aligned into One row and spread length direction is parallel to each other, ledger-plate is fixed together with handpiece body, and cutting blade with ledger-plate in arrangement to grow The mode mutually slided on degree direction is installed togather with ledger-plate, and axle sleeve, transmission shaft, driven tooth are fitted in handpiece body Wheel, eccentric body, driving gear, driving gear are engaged with driven gear, and driven gear is in a manner of perpendicular to transmission shaft and transmission The rear end of axis is affixed with one heart, and axle sleeve is sleeved on transmission shaft, and transmission shaft is inclined from the front end that axle sleeve front opening stretches out and eccentric wheel The heart is affixed, and blocking portion is installed on ledger-plate, and eccentric wheel body is disposed in blocking portion with and in transmission shaft place The mode of mandrel line rotation is slidably matched with card limit portion inner surface, and the rear end of handpiece body and the front end of front shell are fixed to each other and match It connects, power motor is installed in front shell, the front end of power motor from the power output shaft that its casing is stretched out in front is coaxially solid Driving gear is connect, power motor passes sequentially through the front end of power output shaft, driving gear, driven gear, transmission shaft driving bias Wheel rotates and drives cutting blade opposite stationary knife on the spread length direction of cutting blade and ledger-plate by eccentric wheel and blocking portion Piece moves back and forth, and the rear end of front shell and the front end of aft case are fixed to each other mating, and electronics is fixed in aft case Governor, electron speed regulator are electrically connected power motor with the mode for controlling the power output shaft speed of power motor, and feature exists In: aft case peripheral wall offers air inlet port close to the position of its rear end, is equipped on air inlet port and covers air inlet port But the smooth dust cover of air inlet port is kept simultaneously, is installed with negative pressure with the junction inside aft case inside front shell The pod and venthole offered by negative-pressure guide cover rear end cover wall is interconnected, after the power output shaft of power motor End stretches out its casing from rear and is equipped with fan, and fan is equipped with when that can pass through fan in rotation in negative-pressure guide cover The negative pressure of generation drive air successively through air inlet port, aft case, venthole, front shell, cut all knives of horsehair cutter head Gap one-way flow between piece.

The technical characterstic of the utility model: power transmission deceleration device is primary speed-down gear, and overall structure is simple, tight It gathers, monnolithic case is small in size, light-weight；Front shell is to hold part, very thin, meets body mechanics' design principle, by making User is not easy to fatigue when used for a long time；The large scale primary transmission mode that driven gear is meshed with driving gear reduces power and passes Energy loss during dynamic reduces gearing friction contact area and to generate heat less under haircut working condition；After power motor The exposed axis in portion installs fan, and fan is placed outside except power motor, so that being not easily accessible dust or hair stubble inside power motor, protects Use state and the service life of power motor are demonstrate,proved.The cooling-fan installation of power motor is by fan, negative-pressure guide cover, power electric The air outlet in the air duct, handpiece body that are equipped between machine and handle housing, the air inlet of dustproof cover form, the cooling-fan installation knot Structure makes cooling wind other than it can cool down to power motor, and wind is blown out in the gap between handpiece body and horsehair blade, can Certain cooling effect is played to horsehair blade；The power motor for providing power is replaced traditional exchange by DC Brushless Motor Series-wound motor, which has the features such as stabilization of speed, power are strong, mechanical efficiency is high, fever is few, and uses 36V low-voltage direct Electricity, it is ensured that haircut work is more safe and reliable.

The utility model improves sheepshearing haircut in the presence of a harsh environment by the transformation to haircut power transmission arrangment Service performance, durability and flexibility.
