Abstract
The present invention belongs to an automatic sewing device, in particular to a feeding mechanism of a lock seaming machine. The present invention is the feeding mechanism of the lock seaming machine, comprises a needle plate, a feedin tooth and a presser foot, and has the structural key point that the working cross-section area of the feeding tooth is 35-120 mm<SUP>2</SUP>. An elastic band guiding groove is arranged in the middle of the front end of a surface relative to the feedin tooth. The present invention has the advantages that an improvement is performed to the prior equipment aiming at the characteristic of a processed product, the change is small, but, a defect existing in a healing working procedure of plastic products such as a bathing cap permanently perplexed is basically solved, the quality of the products is improved, and a defective index is reduced. An elastic band guiding groove is increased to ensure that the whole stress of the feeding mechanism is uniform, the frequency of adjusting presser foot during the process is reduced, and the labor efficiency is improved. The present invention is produced in production practice, and the present invention has strong practicability.
Description
Technical field
The invention belongs to automatic sewing device, especially belong to a kind of feed mechanism of cap seaming machine.
Background technology
The feed mechanism of present cap seaming machine is sent tooth to by needle plate, presser feet, front and back respectively and is formed, Fig. 1 is the structural representation of existing needle plate 1, design has presser feet groove 11, needle tray 12, cutting knife groove 13 on the needle plate 1, Fig. 2 is for sending the structural representation of tooth to before existing, Fig. 3 is for sending the structural representation of tooth to after existing, Fig. 4 is the left view of Fig. 3, and Fig. 5 is the structural representation of presser feet, and Fig. 6 is the upward view of Fig. 5.Because cap seaming machine is to use on the textile industry, its main processing object is at cloth, sends tooth to and presser feet closely cooperates, and the contact area between them is generally at 350-450mm
2When using it for making as elastic cord such as bathing cap and plastic sheeting lock seaming, because the flexibility of plastics is not as cloth, sharp feeder is usually with the plastic sheeting scratch, serious even broken hole occurs, cause the degree of tightness zone circle to separate when strutting easily with plastics, the contact area of sending between tooth and the presser feet is big more, damage serious more, contact area greatly also makes the stationarity of presser feet be affected simultaneously, in case presser feet tilts will occur and plastic sheeting can't be advanced or the scratch plastic sheeting, therefore needs the frequent balance of adjusting presser feet in process, increase working strength of workers, reduced efficiency.
Summary of the invention
The objective of the invention is to overcome the shortcoming of cap seaming machine, provide a kind of plastic sheeting that do not damage, the feed mechanism of the cap seaming machine that can improve the quality of products.
The technical solution adopted in the present invention is a kind of feed mechanism of cap seaming machine, comprises needle plate, sends tooth to, presser feet, and its structural feature is to send to that the working sections of tooth is long-pending is 35-120mm
2
What is called is sent the long-pending cross sectional area of sending tooth root to that is meant of working sections of tooth to.
Because the toughness of plastics and the flexible cloth that is not so good as are sent to tooth easily and hinder, so should reduce the contact area of sending between tooth and the presser feet, contact area is the smaller the better under the situation that can finish the work of sending to.The inventor passes through test many times, finds to be 35-120mm when the working sections of sending tooth to is long-pending
2, promptly send contact area between tooth and the presser feet at 35-120mm
2Between the time, just can finish the work of sending to, also less to the damage of plastic sheeting.
The present invention also can further be improved to: send tooth to before having only one, send tooth after the cancellation to, send the long-pending 40-100mm of being of working sections of tooth to
2
Send original former and later two to tooth and change one into, help reducing the contact area of sending between tooth and the presser feet.
Send tooth to and can be 2-4 row tooth, generally sending tooth to is 3 row teeth, and the facewidth in the middle of it and the stand out scope of elastic cord are between-1.5mm-+1mm, and the crest end of sending tooth to is a cambered surface.
The inter-lobe clearance of sending tooth three row teeth to is 0.5-2mm, and every row tooth has the 2-8 tooth respectively, sends under the prerequisite of function realizing, the few more damage to plastics of the number of teeth is more little.
Also can one elastic band guiding groove be arranged in presser feet and the front end centre of sending the tooth facing surfaces to, feature at converted products: one deck elastic cord is arranged in the product junction, thicker, gathering sill is set on presser feet one, both sending to of product was played guide effect, improve the crudy of product, also make whole feed mechanism stressed evenly, reduce process and adjust the number of times of presser feet, reduce working strength of workers, raise labour efficiency.
The invention has the advantages that, existing equipment is improved, change for a short time, but fundamentally solved the defective that plastic products closing in operation such as long-term puzzlement bathing cap exists, improved the quality of product, reduce percent defective at the characteristic of converted products.Increase elastic band guiding groove, improve the crudy of product, also make whole feed mechanism stressed evenly, reduce the number of times that process is adjusted presser feet, reduce working strength of workers, raise labour efficiency.The present invention produces in production practices, has very strong practicality.

The specific embodiment
A kind of feed mechanism of cap seaming machine comprises needle plate 1, sends tooth 2 to, presser feet 3, is that with the difference of existing feed mechanism its working sections of sending tooth to is long-pending little, only is 35-120mm
2, to send tooth 2 to and be 2-4 row tooth, inter-lobe clearance is 0.5-2mm, and sending tooth 2 every row teeth to has the 2-8 tooth respectively, and presser feet 3 is having an elastic band guiding groove 31 with the front end centre of sending tooth 2 facing surfaces to.
Below in conjunction with view the present invention is described in detail
As Fig. 7, Fig. 8, Fig. 9, shown in Figure 10, a kind of feed mechanism of cap seaming machine, comprise needle plate 1, send tooth 2 to, presser feet 3, be that with the difference of existing feed mechanism its working sections of sending tooth to is long-pending little, send tooth to before generally having only one, as Fig. 7, shown in Figure 8, send that the working sections of tooth 2 is long-pending only to be 40-100mm to
2What is called is sent the long-pending cross sectional area of sending tooth root to that is meant of working sections of tooth to, as the A-A cutaway view among Fig. 7, sending tooth 2 to is three row teeth, the facewidth in the middle of it and the stand out scope of elastic cord-1.5mm-+1mm between, its inter-lobe clearance is 0.2-1.2mm, and every row tooth has 3 teeth respectively, and the crest end 21 of sending tooth 2 to is cambered surface.As shown in Figure 9, needle plate 1 has also been done corresponding improvement, the position of presser feet groove 11 and size with send tooth to and adapt, as shown in figure 10, presser feet 3 with the front end of sending tooth 2 facing surfaces in the middle of an elastic band guiding groove 31 is being arranged.
