A kind of thread cutting device simple in structure

Technical field

The utility model relates to a kind of thread cutting device.Be specifically related to a kind of two thread cutting devices of making line between the part that are used to cut off.

Background technology

At present, existing shawl (or other makes part) as shown in Figure 5 several of form when continuously producing overseam are made the part connector, needs will adjacent junction, two shawl both sides over-lock seam when disconnecting, need artificial are cut off everywhere one by one, not only the amount of labour is big, and operating efficiency is extremely low.For this reason, the applicant has applied for that on October 31st, 2008 name is called the Chinese patent (application number is 200820091262.3) of " being used to cut off two thread cutting devices of making line between the part ", but thread cutting device described in the literary composition exists complex structure, cost higher, is unfavorable for applying.

The utility model content

The utility model exists complex structure, cost problem of higher in order to solve existing thread cutting device, and then a kind of thread cutting device simple in structure is provided.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: a kind of thread cutting device simple in structure, described thread cutting device comprises frame, rotary body frame, two cutoff tools, hold-down mechanism, back shaft and sprocket wheels, described hold-down mechanism be positioned at the rotary body frame directly over and be installed on the frame, described thread cutting device also comprises cutting knife lowering or hoisting gear and four separators; The rotary body frame is installed on the back shaft, the two ends of back shaft are installed on the frame respectively, sprocket wheel is packed on the boss that rotary body frame one side end face is provided with, four separators are uniform to be installed on the outer surface of rotary body frame, the cutting knife lowering or hoisting gear is installed on the frame, and two cutoff tools are installed in respectively on the cutting knife lowering or hoisting gear.

The utlity model has following beneficial effect: the utlity model has advantage simple in structure, reasonable in design, with low cost, be beneficial to and apply.But use the utility model fast shut-off continuous line of making between the part as shown in Figure 5, improved efficiency greatly, reduced working strength of workers, for the production of shawl automation provides guarantee.

Description of drawings

Fig. 1 is a front view of the present utility model, and Fig. 2 is the left view of Fig. 1, Fig. 3 be the B of Fig. 1 to view, Fig. 4 is the C-C cutaway view of Fig. 2, Fig. 5 links to each other to make the structural representation of part.

The specific embodiment

The specific embodiment one: shown in Fig. 1～5, the described thread cutting device simple in structure of present embodiment comprises frame 1, rotary body frame 2, two cutoff tools 3, hold-down mechanism 4, back shaft 12 and sprocket wheels 5, described hold-down mechanism 4 be positioned at rotary body frame 2 directly over and be installed on the frame 1, described thread cutting device also comprises cutting knife lowering or hoisting gear 7 and four separators 8; Rotary body frame 2 is installed in (rotary body frame 2 is rotated along back shaft 12) on the back shaft 12, the two ends of back shaft 12 are installed in respectively on the frame 1, sprocket wheel 5 is packed on the boss that rotary body frame 2 one side end faces are provided with, four separators 8 are uniform to be installed on the outer surface of rotary body frame 2, cutting knife lowering or hoisting gear 7 is installed on the frame 1 by the bolt of cylinder intermediate support, and two cutoff tools 3 are installed in respectively on the cutting knife lowering or hoisting gear 7.The power of rotary body frame 2 is to realize by the sprocket wheel or the belt pulley that are installed on the rotary frame.

The specific embodiment two: as shown in Figure 4, the described cutting knife lowering or hoisting gear 7 of present embodiment is made of cylinder 11, knife rest 15 and two vertical bars 13, two vertical bars 13 pass two horizon bars 14 that frame 1 is provided with respectively, two vertical bars 13 can slide up and down along two horizon bars 14, cylinder 11 is between two vertical bars 13, the cylinder body of cylinder 11 is affixed with the horizon bar 14 that is positioned at the below, knife rest 15 is fixed on the lower end of piston rod of two vertical bars 13 and cylinder 11, and cutoff tool 3 is equipped with at the two ends of knife rest 15 respectively.Described cutting knife lowering or hoisting gear 7 is simple in structure, and is easy to control.Other composition and annexation are identical with the specific embodiment one.

The specific embodiment three: as shown in figures 1 and 3, the profile of the described separator 8 of present embodiment is tapered.Other composition and annexation are identical with the specific embodiment one or two.

Operation principle

When power passes over also driven rotary body frame 2 rotations by sprocket wheel 5, be installed in the separator 8 on the rotary body frame 2, when entering the opening 23 between the two shawl cloth, along with rotary body frame 2 rotate to the upright position time (separator 8 forwards the top of rotary frame 2 to), hold-down mechanism 4 is at first cylinder 9, under the promotion of second cylinder 10, pressure roller 6 on the hold-down mechanism 4 is pressed onto on the surface of rotary body frame 2, simultaneously cutting knife lowering or hoisting gear 7 makes heatable cutoff tool 3 stretch out under the promotion of cylinder 11, and the line 21 that will (frame is between inclined-plane, separator 8 both sides) both sides links to each other scalds disconnectedly.Hold-down mechanism 4 can make all clothes (shawl cloth 22) location on rotary body frame 2 reliably, hold-down mechanism 4 compresses cloth automatically when tangent line, make shawl cloth can follow rotary frame 2 rotations continuously, guarantee that separator 8 can enter in the next opening smoothly, finish next working cycles.

Voltage on the heatable cutoff tool 3 adds like this, and it is heatable or cutoff tool 3 energisings are promptly heatable that connection can be heated the mount pad energising of blade 3, realized that energising makes cutoff tool 3 heating.

The line that both sides are linked to each other is boiling hot has no progeny finishing, under the control of travel switch, second cylinder 10 of hold-down mechanism 4 and the cylinder 11 of cutoff tool lowering or hoisting gear 7 are at first mentioned, this moment, rotary body frame 2 was rotated along label direction, turn to down opening between the two shawl cloth separator 8 is entered and make hold-down mechanism 4 left side pressure rollers 6 not with separator 8 interferences, under the control of travel switch, first cylinder 9 of hold-down mechanism 4 is mentioned, and the pressure roller 6 on the hold-down mechanism 4 is risen.Power on the rotary body frame 2 is by being installed in (referring to Fig. 1～5) that sprocket wheel 5 on rotary frame 2 ends or belt pulley are realized.
