The utility model relates to the improvement invention of the tufting mechanical device of desk-top flat seam machine, particularly be a kind of machinery that on base cloths such as cotton, nonwoven fabric, Polypropylence Sheet, carries out flocking.

In the prior art of daily life, in the toilet, the doorway, room brings in the room for preventing sole mud dust, often all be placed with a flocking foot pad or plastics foot pad, be commonly called as Pad made of cloth with hair like sheet on one surface, some clusters round this Pad made of cloth with hair like sheet on one surface on the plastics base cloth with the plastics silk, and some Pad made of cloth with hair like sheet on one surface is then with yarn braiding or artificial flocking, the expense of not only taking a lot of work material, and cost is expensive, and is difficult to weave the Pad made of cloth with hair like sheet on one surface of various different patterns.

Problem in view of the known technology existence, the purpose of this utility model is intended to disclose a kind of mechanical device that utilizes fiber yarns such as ACRYLIC YARNS, cotton yarn or polypropylene staple fibre spun yarn to carry out tufting on base cloths such as cotton, plastic flat fiber cloth, nonwoven fabric, this machinery can not only reduce labor intensity significantly, increase work efficiency, reduce cost, increase business efficiency.And can be according to different user, the folk custom style of different regions, flocking goes out various colourful pattern to satisfy the needs of modernization life.

The utility model is finished as follows, the tufting mechanical device includes main shaft, wire agency, cloth feeding mechanism and cut-pile mechanism, one group of eccentric wheel is housed on the described main shaft, by a motor drives, described eccentric wheel is sent to other mechanisms by each connecting rod with the power of motor to described main shaft by a belt.Described wire agency is provided with eedle, and described eedle is installed on the shank of band needle stand, on the described needle stand 1-30 piece of eedle can be installed simultaneously, and by connecting rod, shank drives the eedle seat to described motion-promotion force and eedle is done the oscilaltion campaign by eccentric wheel.Take-up board is fixed on the shank, described cloth feeding mechanism is provided with presser feet and feed dog, described feed dog is installed on the feed dog seat, the feed dog seat is driven by swing balance staff and the balance staff that swings up and down, and described swing balance staff and the balance staff that the swings up and down connecting rod by separately respectively are connected with eccentric wheel on the main shaft; Described cut-pile mechanism is provided with the crochet hook balance staff and is connected with the crochet hook seat, makes crochet hook do swing, and the cutter balance staff is connected the drive cutter by connecting rod and swings up and down with the crochet hook balance staff.

The utility model is compared with known technology, have rational in infrastructure, volume is little, flexible operation is changeable, can make the Pad made of cloth with hair like sheet on one surface of difformity different-style,, bring positive result of use will for the flocking industry according to the tufting mechanical device of the utility model design motif made.

The utility model has following accompanying drawing

Fig. 1 is a front view of the present utility model

Fig. 2 is a side-looking structural representation of the present utility model

Fig. 3 is the angle configurations figure of each working stage of the utility model.

Accompanying drawing has been represented structure of the present utility model and embodiment, further describe each relevant details of embodiment below more in conjunction with the accompanying drawings, whole tufting mechanical device is made up of four parts, be main shaft I, wire agency II, cloth feeding mechanism III and cut-pile mechanism IV, described main shaft I is driven by a radio station machine, one group of eccentric wheel I1 is housed on described main shaft I, I2, I3, I4, described each eccentric wheel drives other mechanical operation respectively, described wire agency II is provided with eedle II1, needle stand II2, described eedle II1 is contained on the needle stand II2, and can be according to tufting area and pattern, 1-30 piece of eedle that does not wait is installed on needle stand, described eccentric wheel I1 is connected with shank II3 by connecting rod II4, and take-up board II5 is fixed on the shank II3, and its knitting wool VI penetrates the eedle eye after by tensioner II6 and take-up board II5.Described cloth feeding mechanism III is made up of presser feet III1, feed dog III2, feed dog seat III3 and seesaw the balance staff III4 and the balance staff III5 that moves up and down etc., seesaw the balance staff II4 and the balance staff III5 that moves up and down respectively by connecting rod III6 separately, and III7 is driven by the eccentric wheel I2 of I on the main shaft and I3 and carries out reciprocally swinging.Described cut-pile mechanism IV is provided with crochet hook balance staff IV1, crochet hook IV3, cutter balance staff IV4 and cutter IV6.When eedle moves downward, take-up board II5 moves downward, VI carries downwards knitting wool, when eedle moves upward, take-up board II5 moves upward, knitting wool IV pulled out from tensioner II6 to the next cycle of operation prepare, when base cloth is sent into cloth feeding mechanism III, presser feet III1 and feed dog III2 can clamp its cloth, by the eccentric wheel I2 on the main shaft I, I3 passes through connecting rod III6 separately respectively, III7 drives the balance staff III4 that seesaws and carries out reciprocally swinging with the balance staff III5 that moves up and down, adjust the swing order in good time, make feed dog seat III3 and feed dog III2 by advancing, descend, retreat, rise, the order of advancing again, unified step with eedle II1, carry out the motion of similar circumference, collaborative presser feet III1 clamps machining object and moves forward when feed dog III2 advances, the time A_A ' that machining object is moved forward is adjusted into eedle and withdraws from time C before time C ' behind the machining object V and eedle enter machining object, make the work feed process not be subjected to the obstruction of eedle II1, the base cloth that pierces through machining object with knitting wool as eedle II1 is during near the minimum point F of eedle II1, crochet hook balance staff IV1 drive crochet hook IV3 is in time pasting eedle II1 and is catching on knitting wool, after hooking knitting wool, eedle rises and withdraws from the base cloth of machining object V, and knitting wool is stayed on the base cloth because allow crochet hook catch on, driving cutter IV6 by cutter balance staff IV4 again cuts knitting wool, make the knitting wool of an original round become two fine hair, crochet hook balance staff IV1 and cutter balance staff IV4 are connected together by a connecting rod IV7 and allow an eccentric wheel I4 on the main shaft drive by a connecting rod IV8 to carry out reciprocally swinging, make crochet hook IV3 and cutter IV6 finish each with the unified step of eedle and process cycle of operation.The motion of each part of this machinery all will be unified mutual coordination.Run to where begin work feed as eedle,, all command control by one group of eccentric wheel on the main shaft to where beginning to collude line.Each whole part is moved the angle configurations of relative main shaft operation and is seen Fig. 3, arrow indication A is that work feed begins to finish to A ' work feed, beginning clipping from arrow B finishes to B ' clipping, beginning eedle from arrow C thrusts machining object and withdraws from machining object to C ' eedle, arrow D is that crochet hook hooks yarn, and E, F are respectively the top dead centre and the lower dead center of eedle.
