Abstract
The utility model belongs to sewing machine technical field, relating in specific to an abrasive belt gearing of an automatic cutter knife grinding mechanism. The gearing is consisted of a bearing, an annulet shaft and an upper and a lower catch; wherein, the bearing is arranged on the annulet shaft, and is positioned axially by the upper and lower catch; steps are provided in the catch to allow the free rolling of bearing outer ring and prevent the abrasive belt from falling. The annulet shaft is vertically fixed on the shaft seat with bolts, and the bearing is driven by the abrasive belt. The apparatus overcomes the shortcomings of traditional device, which enables the abrasive belt to run in a balanced and flexible way; in addition, the bearing has a high precision and is wearing-proof, thereby the durability of the apparatus and property of the complete machine is improved.
Description
Technical field
The utility model belongs to the sewing machine technical field, is specifically related to a kind of abrasive band transmission device of cutting out machine automatic grinding machinery.
Background technique
The automatic grinding cutting out machine is the main machinery of clothing industry, in the abrasive band transmission system of traditional cutting out machine automatic grinding mechanism, though little wheel shaft is through heat treatment, there is hardness on the surface, but, increased friction in the transmission of abrasive band because single load bearing causes the concentrated wear device serious, be prone to the jumping zoning, noise is also relatively more serious.
Summary of the invention
At the problem that conventional construction cutting out machine automatic grinding mechanism abrasive band transmission device exists, the utility model improves the abrasive band transmission device.This transmission device is made up of bearing, little wheel shaft and upper and lower catch, and wherein original slip steamboat replaces with bearing, and Bearing Installation is on little wheel shaft, by upper and lower catch axially locating, catch is provided with step, and it is without hindrance to guarantee that bearing outer ring rolls, and can stop that the abrasive band comes off.The steamboat axle is anchored on the wheel seat with screw, guarantees vertical.Bearing is by the abrasive band transmission.This device has overcome the deficiency of conventional apparatus, and abrasive band fortune is passed steadily, flexibly, and bearing accuracy, hardness height, and the wearing and tearing of mechanical parts have improved serviceability when significantly having reduced the abrasive band transmission, have also improved the complete machine performance.Its structure such as Fig. 4, shown in Figure 5.

Fig. 2 is knife board assembly overlooking surface figure.
Fig. 3 is a knife board assembly kinematic scheme.
Fig. 4 is a slip steamboat component drawings.
Fig. 5 is a slip steamboat assembly profile.
Number in the figure: 1 is the knife board assembly, and 111 are the sharpening grommet screw, and 112 is the abrasive band, 113 is two-way screw mandrel back-up ring, and 114 is two-way screw mandrel lining, and 115 is 24 tooth gears, 116 is the knife board cover plate, and 117 is two-way screw mandrel, and 118 is right spring, 119 are sharpening grommet screw pad, and 120 are sharpening grommet screw lining, and 121 is wearing plate, 122 is the right pad of whetting a knife, and 123 is left side sharpening pad, and 124 is knife board, 125 is fillister head screw, 126 are slip steamboat spring, and 127 are the transmission steamboat, and 128 are transmission steamboat rubber sleeve, 129 is pulley spindle, 130 are transmission steamboat lining, and 131 is 8 tooth wheel shafts, and 132 is duplicate gear, 133 is the duplicate gear lining, and 134 is elasticity garden pin.
Embodiment
The automatic grinding machine structure of cutting out machine as shown in Figure 1-Figure 3.Through the transmission of 8 tooth wheel shafts 131 the two-lines road is arranged, one is to be followed successively by to transmit duplicate gear 132,24 tooth gears 115, make two-way screw mandrel rotation drive the 1 upper and lower work of knife board assembly.See also Fig. 1, Fig. 3.
Another circuit be through 8 tooth wheel shafts 131, successively transmit transmission steamboat 127, elastic cylindrical pin 134, transmission steamboat rubber sleeve 118, make abrasive band 112 rotation drive 2 work of slip steamboat assemblies.See Fig. 1 and shown in Figure 3.Improving back slip steamboat assembly 2 sees shown in Figure 4.By bearing 214, steamboat axle 212, upper and lower catch 213 is formed, abrasive band 112 drive bearings 214, and bearing 214 is installed on the steamboat axle 212, upper and lower catch 213 axially locating, on the catch 213 step is arranged, it is without hindrance to guarantee that bearing outer ring rolls, and can stop that abrasive band 112 comes off, steamboat axle 212 usefulness sunk screws 215 are anchored on the wheel seat 211, guarantee vertical.After the little wheel assembly that slides is assembled by the figure requirement, wheel seat 211 (wheel seat has left and right) is gone up rectangular frame, fill in pin on the knife board by left and right, load onto slip steamboat spring 126, spring one end plug is gone into knife board pin upper groove, and the other end is fixed on the wheel seat, the screw 125 of screwing on, play position-limiting action, the flexible under external force nothing card of the little wheel assembly phenomenon of sliding can link to each other the abrasive band and consult Fig. 1 with transmission steamboat 127, bearing 214.Device makes abrasive band running steadily, flexibly after improving, and bearing accuracy, hardness height, and the machinery wearing and tearing of part in addition improve serviceability when significantly having reduced the abrasive band transmission.
Slip steamboat assembly improvements are to replace the slip steamboat with bearing, are about to former sliding friction and change rolling friction into, reduce other part wearing and tearing, improve serviceability, because the abrasive band ensuring smooth transmission can reduce the sharpening noise, have improved the complete machine performance.
