Abstract
The utility model discloses an electromagnetic sewing machine, which comprises a machine head and a stand connected with each other, a needle feeding bar is disposed in the machine head, a needle is connected with the needle feeding bar, an attracting block is arranged at the lower end of the needle feeding bar, an upper electromagnet that adsorbs the attracting block is arranged in the machine head, and a lower electromagnet that adsorbs the attracting block is arranged in the stand, an upper switch is arranged on the machine head, the attracting block is respectively in contact with the upper switch and a lower switch, the lower switch is arranged on the stand, the upper switch is electrically connected with the lower electromagnet, and the lower switch is electrically connected with the upper electromagnet; and the upper electromagnet is an electromagnet with a coil, and the lower electromagnet is an electromagnet with a coil. Compared with the prior art, the utility model changes the mechanical transmission of the traditional sewing machine needle feeding bar into electromagnetic drive, the structure is greatly simplified, the manufacturing cost is greatly reduced, and the noise during operation is greatly lowered.
Description
Technical field
The utility model relates to the sewing machine technique field, especially a kind of electromagnetism Sewing machines by Electromagnetic Drive.
Background technology
Present widely used family expenses and industrial sewing machines, it send shank mostly for the machine driving form, and it exists complex structure, manufacturing cost higher, and the bigger shortcoming of noise during work has been brought many worries to every aspect thus.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency at above-mentioned technical problem, and a kind of Electromagnetic Drive Sewing machines is provided, and it is higher that it can solve complex structure, manufacturing cost that traditional Sewing machines exists, the bigger problem of noise during work.
The utility model is achieved through the following technical solutions: a kind of electromagnetism Sewing machines, it comprises interconnective head and support, be equipped with in the head and send shank, eedle is connected with sending shank, be provided with an adhesive piece in the described lower end of shank of sending, in described head, be provided with absorption described adhesive piece on put magnet, in described support, be provided with the lower electromagnet of the described adhesive piece of absorption, switch on head is provided with, the adhesive piece is respectively with last, following switch contacts, support is provided with down switch, and the described switch of going up is electrically connected with lower electromagnet, and described switch down is electrically connected with the described electromagnet of going up.
Described upward electromagnet is the electromagnet that has coil, and described lower electromagnet is the electromagnet that has coil.
Described upward switch is arranged on the lower surface of head, and described switch down is arranged on the upper end of support.
Compared with prior art, the utility model changes traditional Sewing machines, and to send the machine driving of shank be Electromagnetic Drive, makes that its structure is simplified greatly, noise significantly reduces when the big reduction of manufacturing cost, work.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Electromagnetism Sewing machines of the present utility model, it has interconnective head 2 and support 6, be equipped with in the head 2 and send shank 10, eedle 5 is connected with sending shank 1, and adhesive piece 4 is connected with the lower end of sending shank 1, and upper and lower electromagnet 3,7 is installed in respectively in head 2, the support 6, and it is coupled respectively, last switch 9 is connected with the lower end of head 2, and following switch 8 is connected with the upper end of support 6, and adhesive piece 4 contacts with upper and lower switch 9,8 respectively.Upper and lower electromagnet 3,7 is respectively the electromagnet that has coil.Adhesive piece 4 is a silicon steel sheet.
During making, process various parts assemblings by above-mentioned requirements and get final product.During use, after connecting power supply, because of being touched by adhesive piece 4, last switch 9 makes lower electromagnet 7 conductings, 4 of adhesive pieces immediately by lower electromagnet 7 adhesives to the bottom, and drive and send shank 1 to move downward, at this moment, adhesive piece 4 has touched time switch 8 makes electromagnet 3 conductings, adhesive piece 4 again by last electromagnet 3 adhesives to top, and drive and send shank 1 to move upward, go round and begin again with this.Technology part and circuit connecting section branch that the utility model is not described in detail are known technology.
