Abstract
A leather slitting device is provided with a fixed blade, a movable blade sliding block baffle plate and a needle bar movable blade connecting block on the basis of the structure of an original common sewing machine. The movable blade and the fixed blade form a shearing structure. The moving blade sliding block baffle and the needle bar moving blade connecting block are positioned at the upper part of the moving blade; the fixed blade is fixed on the bottom plate; one end of the moving blade is connected with the bottom plate, and the other end of the moving blade is sequentially connected with the moving blade sliding block baffle, the needle bar moving blade connecting block and the needle bar. The device utilizes the working principle of the up-and-down reciprocating motion of a needle rod of a common sewing machine to drive the needle rod, and drives the movable blade to do up-and-down shearing reciprocating motion through the movable blade connecting block and the movable blade sliding block baffle plate of the needle rod so as to achieve the purpose of shearing leather strips with the fixed blade. Meanwhile, the width of the open strip is controlled by the needle gage mark disc. The utility model discloses an use, can alleviate intensity of labour effectively, productivity gain guarantees the leather and opens a quality. The device is suitable for wide application in slitting in leather clothing and shoes and hats industries.
Description
Technical field the utility model belongs to cutting sewing auxiliary material device, particularly a kind of strip device of opening that is used for leather sewing auxiliary material.
Background technology is through preliminary search, and before the utility model was made, general ordinary sewing machine is not equipped with leather opened strip device, so all operations by hand.During operation, setting-out on leather substance is earlier cut off leather substance or scratch along setting-out with scissors or cutter by hand then.This traditional-handwork method, the labour intensity height, production efficiency is low, and the manual leather billot quality of making does not guarantee.
The summary of the invention the purpose of this utility model provides a kind of leather that is exclusively used in leatherwear and the shoes and hats manufacturing and opens bar auxiliary material device.The use of this device can reduce labor intensity, and boosts productivity, and can guarantee again that simultaneously leather opens the consistence of bar quality.The purpose of this utility model realizes by following technical proposals:
A kind of leather is opened strip device, is to be obtained by the improvement of ordinary sewing machine.It is driven belt pulley successively, is gone up axle, needle bar crank, thread take-up crank, shank connecting rod, the transmission of shank phase by extraneous change speed motor, and shank pumps; Simultaneously, the rotation of last axle makes being synchronized with the movement of acquisition of feeding tooth and knife section by tooth fork, feed spool, big connecting rod, the transmission of feed lifting rock shaft phase; In addition, also include pressure exerting arrangement and needle gage bidding quotation, auxiliary feed appliance.Different is that this device also is provided with a ledger-plate and knife section; Knife section and ledger-plate are formed shear constitution, the principle of work of the similar scissors of principle of work of moving fixed two blades; Ledger-plate is fixed on the base plate, also is provided with moving knife slide block plate washer and shank moving knife contiguous block on knife section top; One end of knife section links to each other with base plate, and the other end is connected with shank with moving knife slide block plate washer, shank moving knife contiguous block.Link to each other with extraneous change speed motor by shank, shank connecting rod, thread take-up crank, needle bar crank, last axle, belt pulley.Connect power supply, change speed motor drives belt pulley and rotates, and by above-mentioned drive connection, leather by special-purpose auxiliary feed appliance, just can be obtained cutting out the leather billot of specification unanimity.In addition, can regulate leather by the needle gage bidding quotation and open the bar width.
After adopting leather to open strip device, because labour intensity alleviates, the scope of recruitment and adaptability increase; Production efficiency can improve several times even tens times; Leather billot quality is guaranteed.
Description of drawings Fig. 1 opens strip device and structural representation for leather;
Fig. 2 is the left view of Fig. 1 structural representation;
Fig. 3 is the knife section of Fig. 1 structural representation, the vertical view of ledger-plate part.
Embodiment is further described the utility model below in conjunction with drawings and Examples:
From accompanying drawing 1, accompanying drawing 2 as seen, this device can utilize ordinary sewing machine frame, platen and casing, and external change speed motor and motor push-switch according to processing feeding needs, are opened and closure at any time.The utility model mainly is provided with ledger-plate 7 and knife section 9, moving knife slide block plate washer 10, shank moving knife contiguous block 11.Ledger-plate 7 is fixed on the base plate 8 motionless; One end of knife section 9 can link to each other with moving knife preset pieces on being fixed on base plate 8 by moving knife preset pieces axle, the other end and moving knife slide block plate washer 10, shank moving knife contiguous block 11, shank 12, shank connecting rod 13, thread take-up crank 20, needle bar crank 21, goes up axle 22 and links to each other with belt pulley 1.Moving knife slide block plate washer 10 is fixed on above the other end of knife section 9; Shank moving knife contiguous block 11 is fixed on below the shank 12, and links to each other with moving knife slide block plate washer 10, knife section 9 the other ends.Pumping of shank 12 and shank moving knife contiguous block 11 just can drive knife section 9 and do to go up the down cut to-and-fro movement.Concrete transmission process is: when shank 12 and shank moving knife contiguous block 11 move upward, moving knife slide block plate washer 10 and knife section 9 are mentioned; When moving downward, knife section 9 is depressed, realized shearing with ledger-plate 7.Extraneous change speed motor drive pulley 1 rotates, drive blades 9 by last axle 22, needle bar crank 21, thread take-up crank 20, shank connecting rod 13, shank 12, shank moving knife contiguous block 11, moving knife slide block plate washer 10 and do to go up the down cut to-and-fro movements, implement the shearing function of knife section 9 and ledger-plate 7.Knife section 9 and ledger-plate 7 are tool steel.Moving knife slide block plate washer 10 and shank moving knife contiguous block 11 are steel.Simultaneously, the rotation that will go up axle 22 by tooth fork 3 and big connecting rod 4 is delivered to feed spool 5 and feed lifting rock shaft 6, is controlling moving up and down and seesawing of feeding tooth 14.In addition, the roller press 15 that is installed on the compressor arm 16 has pressurization, and its reactive force is from stage clip 18, and masterpiece is used for compressor arm saddle 17.Roller press 15 stresses on the size of processing leather upward pressure, can be controlled by pressure regulating screw 19, and pressure increases during screw-in, otherwise pressure reduces.From accompanying drawing 3 as seen, this device also is provided with auxiliary guide function, and leather is sent from the auxiliary feed appliance 23 of special use that is fixed on the base plate 8.Leather is opened the width of bar and can be controlled by needle gage bidding quotation 2, and opening bar width adjusting scope is 2 to 5 millimeters.
