A new type of small-head special multi-needle machine

Abstract

This utility model discloses a novel small-head special multi-needle machine, including a needle clamp with multiple sets of needle mounting slots distributed on it. Each needle mounting slot contains a longitudinal needle. A needle plate is located below the needle clamp, and a feed dog is located below the needle plate. The needle plate has multiple sets of needle holes (B) that mate with the multiple longitudinal needles. The needle plate also has a set of feed dog grooves that mate with the teeth of the feed dog, with each tooth of the feed dog extending into the set of feed dog grooves. A needle presser foot is located above the needle plate, and the needle presser foot has a set of needle holes (A) that align with the sets of needle holes (B) and the longitudinal needles. The design allows for the simultaneous installation of multiple longitudinal needles in the needle clamp, and also includes a needle presser foot, needle plate, feed dog, and curved needle holder that can work with any number of longitudinal needles within a given range. The number of longitudinal needles on the needle clamp can be flexibly adjusted according to specific work requirements, making the overall operation more convenient and flexible.

Description

Technical Field

[0001] This utility model belongs to the field of sewing machine technology, specifically relating to a novel small-head special multi-needle sewing machine. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. Most commonly used sewing machines today consist of a base plate, on which a sewing head is fixed. Various mechanical mechanisms are installed on the sewing head and the base plate, and these mechanisms work together to complete ordinary sewing.

[0003] Existing conventional sewing machines can only install one or a few needles and accessories at the machine head, and cannot be used with multiple needles at the same time.

[0004] Therefore, this utility model designs a novel small-head special multi-needle machine. Utility Model Content

[0005] The purpose of this invention is to provide a novel small-headed special multi-needle machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel small-head special multi-needle machine includes a needle clamp, on which multiple sets of mounting needle slots are distributed, and each mounting needle slot contains a longitudinal needle. A needle plate is provided below the needle clamp, and a feed dog is provided below the needle plate. Multiple sets of needle holes B that cooperate with the multiple longitudinal needles are distributed on the needle plate. The needle plate also has a set of feed dog grooves that cooperate with the teeth of the feed dog, and each tooth of the feed dog extends into the set of feed dog grooves. A needle presser foot is provided above the needle plate, and a set of needle holes A that are aligned with the sets of needle holes B and the longitudinal needles are provided on the needle presser foot. A laterally movable curved needle seat is provided below the feed dog, and multiple transverse curved needles are distributed on the curved needle seat.

[0007] Preferably, the top of the needle presser foot is provided with a pair of fixed connecting ears, and the connecting ears and the needle presser foot are an integral structure.

[0008] Preferably, the top edge of the needle plate is provided with a pair of mounting holes for fixing and installing the needle plate.

[0009] Preferably, the transverse bent needles on the bent needle holder are aligned one by one with the needle holes B group, and the bent needle holder is also provided with an extension mounting base.

[0010] Preferably, the distribution and length of the feed tooth set match the distribution and length of the feed teeth.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention designs a needle clamp that can simultaneously install multiple longitudinal needles, and also designs a needle presser foot, needle plate, feed dog, and needle holder that can work with any number of longitudinal needles within a certain range. This allows the number of longitudinal needles on the needle clamp to be flexibly adjusted according to the specific work needs, making the overall use more convenient and flexible.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a novel small-head special multi-needle machine, including a needle clamp 1, on which multiple sets of needle mounting grooves are distributed, and each needle mounting groove is equipped with a longitudinal needle 2. A needle plate 5 is arranged below the needle clamp 1, and a feed dog 8 is arranged below the needle plate 5. Multiple needle holes B groups 6 are distributed on the needle plate 5 to cooperate with the multiple longitudinal needles 2. The needle plate 5 is also provided with a set of feed dog grooves 7 that cooperate with the teeth of the feed dog 8, and each tooth of the feed dog 8 extends into the feed dog groove. Within the assembly 7, a needle presser foot 3 is positioned above the needle plate 5. The needle presser foot 3 has a group of needle holes A 4 aligned with the needle holes B group 6 and the longitudinal needles 2. Below the feed dog 8 is a laterally movable looper seat 10, on which multiple transverse loopers 9 are distributed. This allows the number of longitudinal needles 2 on the needle clip 1 to be flexibly adjusted according to specific work requirements, as well as the position and number of transverse loopers 9 on the looper seat 10, making overall use more convenient and flexible. In this embodiment, preferably, a pair of fixed connecting ears are provided at the top of the needle presser foot 3, and the connecting ears and needle presser foot 3 are an integral structure for easy installation of the needle presser foot 3.
