Description

Technical Field

[0001] This utility model belongs to the field of fabric positioning technology for embroidery machines, and in particular relates to a fabric positioning device for embroidery machines. Background Technology

[0002] When embroidering fabric with an embroidery machine, the area to be embroidered needs to be outlined using a positioning frame, and backing paper should be placed under the outlined fabric. In actual embroidery, placing the backing paper directly under the fabric can easily cause it to shift and become misaligned, thus losing its padding function. In addition, directly clamping the fabric with the upper and lower parts of the positioning frame can cause the frame to loosen and fall off as the clamping arms move during embroidery, resulting in the fabric falling off the embroidery machine and causing damage and waste to the fabric during the embroidery process.

[0003] To address this issue, we provide a fabric positioning device for embroidery machines to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a fabric positioning device for an embroidery machine. By screwing a paper liner ring onto the lower end of the bottom support ring, the paper liner is clamped between the paper liner ring and the bottom support ring, thus firmly fixing the paper liner under the fabric and preventing it from falling off or shifting during embroidery. By opening a pressure ring groove at the lower end of the upper pressure ring, the fabric to be embroidered is placed over the upper end of the bottom support ring, and the pressure ring groove of the upper pressure ring is pressed against the upper end of the bottom support ring, clamping the fabric on the bottom support ring. The side-top component on the side of the upper pressure ring presses the fabric in the pressure ring groove tightly, preventing the fabric from moving the upper pressure ring during embroidery, which would cause the fit between the upper pressure ring and the bottom support ring to loosen.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 4 This utility model is a fabric positioning device for an embroidery machine, including a bottom support ring 1 and an upper pressure ring 2. The lower ring surface of the upper pressure ring 2 has a pressure ring groove 201. By threading a paper lining ring 101a onto the lower end of the bottom support ring 1, the paper lining is clamped between the paper lining ring 101a and the bottom support ring 1, thereby firmly fixing the paper lining under the fabric and preventing it from falling off or shifting during the embroidery process. By opening the pressure ring groove 201 at the lower end of the upper pressure ring 2, the fabric to be embroidered is placed on the upper end of the bottom support ring 1, and the pressure ring groove 201 of the upper pressure ring 2 is pressed against the upper end of the bottom support ring 1, clamping the fabric on the bottom support ring 1. The side top component 202c on the side of the upper pressure ring 2 presses the fabric in the pressure ring groove 201 tightly, preventing the fabric from moving the upper pressure ring 2 during the embroidery process, which would cause the fit between the upper pressure ring 2 and the bottom support ring 1 to loosen.

[0027] Specifically, the bottom support ring 1 is sleeved in the pressure ring groove 201. A paper lining ring sleeve 101 is fixedly provided on the outer ring of the lower side of the bottom support ring 1. A paper lining ring 101a is screwed into the inner thread of the paper lining ring sleeve 101. A lower pressure ring 202 is fixedly provided on the lower outer side of the upper pressure ring 2. A clamping mounting plate 202a is fixedly provided on both horizontal outer sides of the lower pressure ring 202. Side holes 202b are opened on both horizontal inner sides of the lower pressure ring 202. A side top component 202c is slidably sleeved in the side holes 202b.

[0028] Furthermore, the upper inner ring of the bottom support ring 1 expands outward continuously, while the upper outer ring of the bottom support ring 1 contracts outward continuously, so that after the fabric is placed on the upper end of the bottom support ring 1, the fabric is naturally clamped between the pressure ring grooves 201, preventing the fabric from being deformed by pressure.

[0029] Furthermore, an outer flange 101a-1 is fixedly provided on the outer side of the upper end of the liner ring 101a, and a set of protruding buttons 101a-2 are fixedly arranged in a circumferential array on the lower end face of the liner ring 101a. By rotating the protruding buttons 101a-2, the liner ring 101a is screwed into the liner ring sleeve 101.

[0030] Furthermore, the lower end face of the pressure ring 202 is provided with magnetic post holes 202d in a circumferential array, and a magnetic post 202d-1 is fixedly sleeved inside the magnetic post holes 202d.

[0031] Furthermore, an annular groove 101a-3 is provided on the upper end face of the outer flange 101a-1. A magnetic ring 101a-4 is fixedly sleeved in the annular groove 101a-3. The lower end face of the magnetic post 202d-1 matches the magnetic ring 101a-4. The lower pressure ring 202 presses on the part of the fabric covering the upper end of the outer flange 101a-1. At the same time, the attraction between the magnetic post 202d-1 and the magnetic ring 101a-4 clamps the upper part of the outer flange 101a-1.

[0032] The operation process in this embodiment is as follows:

[0033] Place the backing paper pad at the lower end of the bottom support ring 1, and screw the backing paper ring 101a into the backing paper ring sleeve 101 to clamp the backing paper at the lower end of the bottom support ring 1, preventing the backing paper from shifting during the embroidery process. Cover the part of the fabric to be embroidered onto the bottom support ring 1, and press the pressure ring groove 201 at the lower end of the upper pressure ring 2 onto the upper end of the bottom support ring 1, thereby pressing the fabric at the upper end of the bottom support ring 1 tightly. The side top component 202c on the side of the upper pressure ring 2 presses the fabric in the pressure ring groove 201 tightly, preventing the fabric from moving the upper pressure ring 2 during the embroidery process, which would cause the fit between the upper pressure ring 2 and the bottom support ring 1 to loosen. Insert the clamping mounting plates 202a on both sides of the upper pressure ring 2 into the clamping arms on the embroidery machine, and the embroidery machine embroiders the fabric at the lower end of the upper pressure ring 2.

[0034] Example 2

[0035] Please see Figures 1 to 5 Based on Embodiment 1, the side top assembly 202c includes a side top spring 202c-1 and a side top bead 202c-2. By fitting the side top spring 202c-1 into the side hole 202b and placing the side top bead 202c-2 against one end of the side top spring 202c-1, the side top spring 202c-1 squeezes the side top bead 202c-2 to press the fabric at the upper end of the bottom support ring 1, thereby preventing the upper pressure ring 2 from loosening when the fabric moves during the embroidery process.

[0036] Specifically, one end of the side top spring 202c-1 is fixedly connected to the inner top surface of the side hole 202b, and the side top bead 202c-2 is fixedly connected to the end of the side top spring 202c-1 away from the inner top surface of the side hole 202b.

[0037] Furthermore, a slide rod 202c-3 is fixedly installed on the outer side of the side top bead 202c-2. The slide rod 202c-3 is sleeved inside the side top spring 202c-1. The slide rod 202c-3 passes through the inner top surface of the side hole 202b. An end cap 202c-4 is threaded onto the end of the slide rod 202c-3 away from the side top bead 202c-2.

[0038] The operation process in this embodiment is as follows:

[0039] The part of the fabric to be embroidered is placed over the upper end of the bottom support ring 1. The pressure ring groove 201 at the lower end of the upper pressure ring 2 is pressed against the upper end of the bottom support ring 1 to press the fabric at the upper end of the bottom support ring 1 tightly. The side top spring 202c-1 presses one side of the side top bead 202c-2, so that the side top bead 202c-2 presses the fabric covering the outside of the bottom support ring 1 tightly, thereby preventing the upper pressure ring 2 from loosening when the fabric moves during the embroidery process.
