Description

Technical Field

[0001] This utility model belongs to the technical field of embroidery machines, and in particular relates to a feeding structure for an embroidery machine. Background Technology

[0002] Embroidery machines enable traditional hand embroidery to be carried out at high speed and efficiency, and can achieve the requirements of "multi-layer, multi-functional, uniform and perfect" that hand embroidery cannot achieve. It is an electromechanical product that embodies a variety of high-tech features. As computer embroidery replaces hand embroidery, computer embroidery machines will become the main type of machine in the embroidery industry. In order to stably embroider the fabric, a corresponding feeding structure will be used to transport the fabric.

[0003] However, existing feeding structures lack the ability to adjust the distance based on the fabric width, thus failing to handle fabrics of varying widths and reducing their practicality. Furthermore, during fabric feeding, wrinkles and bulges easily appear, and the lack of fabric smoothing function hinders subsequent embroidery work. Therefore, we provide a feeding structure for an embroidery machine to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding structure for an embroidery machine. The feeding cylinder slides along the surface of the cross shaft to adjust the fabric width. At the same time, the cooperation between the guide roller and the leveling frame facilitates the smoothing of the fabric and ensures stable conveying.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a feeding structure for an embroidery machine, comprising a vertical plate; a flat plate is fixed to the right side wall of the vertical plate; a cross shaft is rotatably connected between two ear plates above the flat plate; feeding cylinders are fitted at both ends of the cross shaft for use with it; multiple rotating plates are bolted to the surface of the feeding cylinder and evenly distributed in a ring around its periphery; U-shaped strips are fitted at the positions corresponding to the feeding cylinders on the upper end of the vertical plate; a leveling frame is fixed to the upper end of the flat plate to the right of the cross shaft; a guide roller is rotatably arranged between the two ear plates on the upper end of the flat plate to the right of the leveling frame; a strip-shaped opening is opened through the side wall of the vertical plate above the flat plate; a sleeve rod is fixed to the left side wall of the vertical plate below the strip-shaped opening.

[0007] The present invention is further configured such that a motor connected to the cross shaft is fixed to the side wall of the flat plate, and the cross shaft and the guide roller are connected by a synchronous belt drive.

[0008] The present invention is further configured such that screw holes are provided on the sidewalls of the U-shaped strips located on the left side of the vertical plate, and the sidewalls of the U-shaped strips connected to the vertical plate are provided with round openings that communicate with the inside of the screw holes.

[0009] The present invention is further configured such that a screw is spirally arranged inside the screw hole, and an abutment plate located inside the circular opening is fixed to the end face of the screw.

[0010] The present invention is further configured such that each of the two sets of feeding cylinders has a connecting sleeve fitted on the cross shaft at opposite end faces, and a connecting plate is fixed on the U-shaped strip side wall located to the right of the vertical plate.

[0011] The present invention is further configured such that a notch is provided on the end face of the feeding cylinder near the connecting sleeve, and an insert ring is fixed on the end face of the connecting sleeve and inserted into the notch, and the insert ring is bolted to the feeding cylinder.

[0012] The present invention is further configured such that the connecting plate is fitted onto the connecting sleeve through a sleeve opening provided on the side wall, the inner wall of the sleeve opening is provided with an inner ring groove, and the outer wall of the connecting sleeve is fixed with a protruding ring located inside the inner ring groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. Control the two sets of U-shaped strips to move in opposite directions at the top of the vertical plate. The U-shaped strips will then drive the feed cylinder to slide along the cross axis, thereby controlling the distance between the two sets of feed cylinders to adjust the fabric of different widths.

[0015] 2. Since the fabric passes through the inside of the leveling frame, when the rotating plate pushes the fabric to the leveling frame, the fabric between the leveling frame and the rotating plate will bulge. Then, the guide roller will pull the fabric, allowing the fabric to pass through the leveling frame one after another. The leveling frame will smooth the fabric, ensuring stable fabric delivery.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 5 This utility model is a feeding structure for an embroidery machine. The feeding cylinder 2 slides along the surface of the cross shaft 5 to adjust the width of the fabric. At the same time, the cooperation between the guide roller 105 and the leveling frame 104 facilitates the smoothing of the fabric and ensures stable conveying.

[0027] Specifically, a vertical plate 1; a flat plate 101 is fixed to the right side wall of the vertical plate 1; a cross shaft 5 is rotatably connected between two ear plates above the flat plate 101; a feeding cylinder 2 is sleeved at both ends of the cross shaft 5 for use with it; multiple rotating plates 201 are bolted to the surface of the feeding cylinder 2 and evenly distributed in a ring around its periphery; a U-shaped strip 3 is sleeved at the position corresponding to the feeding cylinder 2 on the upper end of the vertical plate 1; a leveling frame 104 is fixed to the upper end of the flat plate 101 to the right of the cross shaft 5; a guide roller 105 is rotatably arranged between the two ear plates at the upper end of the flat plate 101 to the right of the leveling frame 104; a strip-shaped opening 102 is opened through the side wall of the vertical plate 1 above the flat plate 101; a motor 4 is fixed to the side wall of the flat plate 101 and is connected to the cross shaft 5 for transmission; the cross shaft 5 and the guide roller 105 are connected by a synchronous belt transmission; a sleeve rod 103 is fixed to the left side wall of the vertical plate 1 below the strip-shaped opening 102.

[0028] The operation process of this embodiment is as follows: Using the above-described structure, the fabric tube is directly fitted onto the sleeve 103, and the end of the fabric passes through the strip opening 102, sequentially passing below the cross shaft 5, inside the leveling frame 104, and below the guide roller 105. Therefore, the rotation of the cross shaft 5 is controlled by the motor 4, which drives the rotating plate 201 to rotate. The friction between the rotating plate 201 and the fabric pushes the fabric towards the leveling frame 104. Furthermore, the contact between the guide roller 105 and the fabric causes the guide roller 105 to pull the fabric, thus drawing it. Simultaneously, the feeding structure is installed at the feeding port of the embroidery machine, causing the fabric to continuously move towards the embroidery machine. When conveying and adjusting the two sets of feeding cylinders 2 according to the width of the fabric, the two sets of U-shaped strips 3 can be controlled to move in opposite directions at the upper end of the vertical plate 1. The U-shaped strips 3 will then directly drive the feeding cylinders 2 to slide along the cross axis 5, thereby controlling the distance between the two sets of feeding cylinders 2 to adjust the fabric width for different widths. Since the fabric passes through the inner side of the leveling frame 104, when the rotating plate 201 controls the fabric to be pushed to the leveling frame 104, the fabric between the leveling frame 104 and the rotating plate 201 will bulge. Then, the fabric is pulled by the guide roller 105, so that the fabric passes through the leveling frame 104 one after another. The leveling frame 104 will smooth the fabric to ensure stable conveying of the fabric.

[0029] Example 2

[0030] Please see Figure 3 and Figure 5 Based on Example 1, the screw 301 controls the contact between the abutment plate 302 and the vertical plate 1 to ensure the stability of the feed cylinder 2 after the position is adjusted.

[0031] Specifically, screw holes 304 are provided on the side wall of the U-shaped strip 3 on the left side of the vertical plate 1. The side wall of the U-shaped strip 3 connected to the vertical plate 1 is provided with a round opening 303 that communicates with the inside of the screw hole 304. A screw rod 301 is spirally arranged inside the screw hole 304. An abutment plate 302 located inside the round opening 303 is fixed to the end face of the screw rod 301.

[0032] The operation process of this embodiment is as follows: After the position of the U-shaped strip 3 at the upper end of the vertical plate 1 is adjusted, the control screw 301 rotates inside the screw hole 304. Then the screw 301 will push the abutment plate 302 to abut against the side of the vertical plate 1, thereby increasing the friction between the abutment plate 302 and the vertical plate 1, ensuring the position of the U-shaped strip 3 is stable, and thus ensuring that the position of the feeding cylinder 2 remains unchanged.

[0033] Example 3

[0034] Please see Figure 4 and Figure 5Based on Example 1, the cooperation between the convex ring 204 and the inner ring groove 307 avoids mutual interference between the connecting sleeve 203 and the connecting plate 305.

[0035] Specifically, each end face of the feeding cylinder 2 is provided with a connecting sleeve 203 that fits onto the cross shaft 5. A connecting plate 305 is fixed to the side wall of the U-shaped strip 3 located to the right of the vertical plate 1. A notch 202 is provided on the end face of the feeding cylinder 2 near the connecting sleeve 203. An insert ring 205 is fixed to the end face of the connecting sleeve 203 and inserted into the notch 202. The insert ring 205 is bolted to the feeding cylinder 2. The connecting plate 305 is fitted onto the connecting sleeve 203 through a sleeve opening 306 provided on the side wall. An inner ring groove 307 is provided on the inner wall of the sleeve opening 306. A protruding ring 204 is fixed to the outer wall of the connecting sleeve 203 and located inside the inner ring groove 307.

[0036] The operation process of this embodiment is as follows: After the cross shaft 5 is driven to rotate, the cross shaft 5 will drive the connecting sleeve 203 and the feeding cylinder 2 to rotate synchronously. At the same time, the convex ring 204 is located in the inner ring groove 307. Therefore, the connecting sleeve 203 will drive the convex ring 204 to rotate in the inner ring groove 307. Through the cooperation between the convex ring 204 and the inner ring groove 307, the connection between the connecting plate 305 and the connecting sleeve 203 is stable, ensuring that the connecting plate 305 will not rotate synchronously with the connecting sleeve 203.
