Abstract
The utility model discloses an electric pencil sharpener with helical hob, and comprises an electromotor, a gear box driving mechanism and a helical hob mechanism, wherein, when a circuit is switched on, electromotor power started by the electromotor is transmitted to a big gear with second level through an electromotor gear; then, the electromotor power is transmitted to a small gear with second level through a sliding friction piece; the electromotor power is transmitted to an axial slide bar through a big gear with third level again; then, the electromotor power is transmitted to the helical hob mechanism through an axial slide sleeve. The utility model has the advantages of reasonable structure, cutting smooth, good quality, small noise and low production cost.
Description
The utility model relates to individual and family expenses sundries, relates in particular to electric screw hobboing cutter pencil sharpener.
Pencil sharpener commonly used at present has two big classes, and the first kind is a single-blade formula pencil sharpener, and thin blade directly is fastened on the knife rest with bolt or screw, by rotating, digs sheet pen bits, and it is simple in structure, but blade is easily blunt, and nib is easily broken, and cutting quality descends fast; Second class is the spiral hobbing cutter pencil sharpener, promptly utilizes the rotation around internal gear of the hobboing cutter be contained on the hob head and the hobboing cutter gear on the hobboing cutter, and cutting is fixed on the pencil of hob head center, digs a sheet pen bits.This kind pencil sharpener must be operated by two hands simultaneously, perhaps in advance pencil sharpener is fixed on an edge, just can a hand operated.
The purpose of this utility model provides a kind of one-hand operation, electric screw hobboing cutter pencil sharpener rational in infrastructure.
The utility model is taked following measures in order to achieve the above object, electric screw hobboing cutter pencil sharpener, it comprises motor, gear case transmission mechanism, spiral hobbing cutter mechanism, shell, loam cake, motor reel is provided with motor gear, spiral hobbing cutter mechanism is provided with hob head, cutter shaft, the hob head center is provided with pencil insertion hole, cutter shaft is provided with hobboing cutter, the hobboing cutter gear, on the pencil sharpener support, be provided with the inner gear ring that matches with the hobboing cutter gear, it is characterized in that gear case transmission mechanism is provided with the I-I power transmission shaft that is parallel to each other, the II-II power transmission shaft, the III-III power transmission shaft, be provided with centring ring on the II-II power transmission shaft successively, II level pinion, the sliding friction sheet, II level gear wheel, II level spring, centring ring, be provided with axial slide bar on the III-III power transmission shaft successively, III level gear wheel, place, III-III power transmission shaft one end is provided with contact chip, following contact chip, motor gear and bevel gear engagement, pinion on the bevel gear and the engagement of II level gear wheel, said hob head lower end is provided with the axial sliding sleeve that matches with axial slide bar, pressing contact chip under the hob head contacts with following contact chip, hobboing cutter gear and internal gear engagement, III level gear wheel and II level pinion slide and mesh.
The utility model has the advantages that: rational in infrastructure, stable cutting, cutting quality is good, noise is little, production cost is low.Can one-handed performance, the feed pressure when utilizing the pencil planing is touched contact chip simultaneously, connects circuit cutting pencil.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is an electric screw hobboing cutter pencil sharpener structural representation;
Fig. 2 is Figure 1A to view;
Fig. 3 is an II level drive mechanism schematic diagram;
Fig. 4 is an III level drive mechanism schematic diagram.
A kind of electric screw hobboing cutter pencil sharpener, it comprises motor 1, gear case transmission mechanism, spiral hobbing cutter mechanism, shell 20, loam cake 22, motor reel is provided with motor gear 2, spiral hobbing cutter mechanism is provided with hob head 18, cutter shaft 21, the hob head center is provided with pencil insertion hole, cutter shaft is provided with hobboing cutter 19, hobboing cutter gear 17, on the pencil sharpener support, be provided with the inner gear ring 15 that matches with the hobboing cutter gear, it is characterized in that gear case transmission mechanism is provided with the I-I power transmission shaft that is parallel to each other, the II-II power transmission shaft, the III-III power transmission shaft, be provided with centring ring 9 on the II-II power transmission shaft successively, II level pinion 4, sliding friction sheet 5, II level gear wheel 6, II level spring 7, centring ring 8, be provided with axial slide bar 12 on the III-III power transmission shaft successively, III level gear wheel 11, place, III-III power transmission shaft one end is provided with contact chip 23, following contact chip 24, motor gear 2 and bevel gear 3 engagements, pinion on the bevel gear and 6 engagements of II level gear wheel, said hob head lower end is provided with the axial sliding sleeve that matches with axial slide bar 12, pressing contact chip 23 under the hob head contacts with following contact chip 24, hobboing cutter gear 17 and inner gear ring 14 engagements, III level gear wheel 11 slides with II level pinion and meshes.Axially the slide bar root is provided with gasket ring 16, is equipped with sliding bearing 13 mutually, thrust bearing 14 with axial slide bar on the pencil sharpener support.The material of hob head 18, ring gear 15, hobboing cutter gear 17, axial slide bar 12 is glass fibre reinforced nylon or glass fiber reinforced polycarbonate, or glass fiber reinforced polypropylene, or polyformaldehyde.The material of motor gear 2, bevel gear 3, II level pinion 4, II level gear wheel 6, III level gear wheel 11 is a polyformaldehyde, or glass fibre reinforced nylon.
During pencil sharpener work, pencil inserts pencil insertion hole, and hob head presses down, and last contact chip contacts with following contact chip, hobboing cutter gear and internal gear engagement, and III level gear wheel and II level pinion slide and mesh.
When circuit is connected, motor start-up makes the rotational power of motor gear be delivered to II level gear wheel, be delivered to II level pinion by the sliding friction sheet again, II level pinion is given III level gear wheel with transmission of power, further by axial slide bar and axial sliding sleeve, give hob head with transmission of power, hob head rotates around cutter shaft, the hobboing cutter gear except with hob head around cutter shaft rotates, self rotates along inner gear ring.Therefore turning to rotating speed of hobboing cutter is different from turning to of hob head and rotating speed, and pencil is fixed again, carries out planing work thus.When pencil sharpener transshipped, the sliding friction sheet on the II-II power transmission shaft skidded, and reaches overload protective function.
