Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to an embroidery press plate for an embroidery machine. Background Technology

[0002] An embroidery machine is a mechanical device used for embroidery. It can input the designed pattern data into the control system, and the control system precisely drives the embroidery needle to shuttle up and down on the fabric based on this data. At the same time, in conjunction with the bobbin thread device, the top thread and the bobbin thread interweave to form embroidery patterns of various stitches.

[0003] An embroidery machine typically consists of several important components working together, including the machine head, frame, control system, and transmission system. The machine head contains many key sub-components, with the embroidery pressure plate being a crucial one. It is generally located above the embroidery area, and its main function is to apply appropriate pressure to the fabric during the embroidery process, preventing displacement or other undesirable phenomena caused by the force of the needle.

[0004] In the process of developing this utility model, the inventor discovered the following problems with the existing technology: 1. Currently, some pressing plates adopt a hollow structure and are fixed using quick methods such as upper and lower plates and magnetic attraction. Due to the frequent up-and-down movement of the embroidery needle and the movement of the embroidery frame, a certain amount of vibration and impact force is generated. The hollow structure cannot withstand these forces well, resulting in slight displacement or shaking of the pressing plate; 2. To facilitate the fitting of fabric, it is common to use the method of fitting the fabric over the outside of the plate. Moreover, many pressing plates often use methods such as overall pressing or magnetic fixation to uniformly process the fabric when pressing it down, without the function of tension adjustment for individual operating areas. This can affect the accuracy of embroidery due to unsuitable local tension. Utility Model Content

[0005] The purpose of this utility model is to provide an embroidery pressing plate for an embroidery machine, solving the problems mentioned in the background art where hollow structures cannot withstand these forces well, resulting in slight displacement or wobbling of the pressing plate and the lack of tension adjustment for individual operating areas. To achieve the above objective, this utility model provides the following technical solution: an embroidery pressing plate for an embroidery machine, comprising a front mounting plate and a rear mounting plate, the front mounting plate and the rear mounting plate being fixedly connected by a fixed side plate, the top of the rear mounting plate being rotatably connected to a movable side plate and a pressing plate, the movable side plate being located directly above the fixed side plate, the pressing plate being located between the movable side plate and the fixed side plate, the top of each movable side plate being threadedly connected to an adjusting screw, the pressing plate having a support plate embedded in it through a slot, the inner wall of the pressing plate being rotatably connected to a first connecting rod and a second connecting rod, the inside of the pressing plate being rotatably connected to a reverse screw, the outer ends of the reverse screw being threadedly connected to connecting seats, and the surface of the front mounting plate being movably connected to tension buckles by springs.

[0007] More preferably, both ends of the outer wall of the movable side plate are provided with pointer-shaped structures that fit against the surface of the rear mounting plate, and the side of the rear mounting plate corresponding to the pointer-shaped structure is marked with a scale.

[0008] More preferably, the front mounting plates are spaced a certain distance apart, the surface of the front mounting plate has a sloping structure, and mounting holes are provided at the lower edge of both the front and rear mounting plates on one side.

[0009] More preferably, the pull buckle is configured with an elastic reset structure by a spring, and the movable side plate and the adjacent end of the pull buckle are both fixedly connected with a cylindrical structure for engaging the pull buckle.

[0020] 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an embroidery press plate for an embroidery machine, including a front mounting plate 1 and a rear mounting plate 2. The front mounting plate 1 and the rear mounting plate 2 are fixedly connected by a fixed side plate 3. The top of the rear mounting plate 2 is rotatably connected to a movable side plate 4 and a press plate 5, respectively. The movable side plate 4 is located directly above the fixed side plate 3, and the press plate 5 is located between the movable side plate 4 and the fixed side plate 3. The top of the movable side plate 4 is threaded with an adjusting screw 6. The press plate 5 is fitted with a support plate 7 through a slot opened inside it. The inner wall of the press plate 5 is rotatably connected to a first connecting rod 8 and a second connecting rod 9. The inside of the press plate 5 is rotatably connected to a reverse screw 11. Both ends of the outer wall of the reverse screw 11 are threaded with connecting seats 10. The surface of the front mounting plate 1 is rotatably connected with a tension buckle 12 by a spring.

[0022] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom of the movable side plate 4 and the top of the fixed side plate 3 are both glued together with rubber layers. The shaft head at the bottom of the adjusting screw 6 is rotatably connected to the top of the rubber layer at the bottom of the movable side plate 4. The rubber layer at the bottom of the movable side plate 4 is tightly attached to the rubber layer at the top of the fixed side plate 3 through the adjusting screw 6. Whether it is a single-layer large-size fabric or a double-layer material like clothing, when it is placed or fitted by the pressure plate 5, the movable side plate 4 and the fixed side plate 3 provide additional fixing points on both sides by pressing up and down. This can effectively limit the horizontal movement of the fabric and ensure that the fabric remains stable in the embroidery area. The rubber layer under the movable side plate 4 can be height adjusted by the adjusting screw 6. This feature allows the device to adapt to fabrics or clothing parts of different thicknesses. Whether it is smooth silk fabric or rough linen fabric, the rubber layer can provide suitable friction, achieving effective pressure fixation while protecting the fabric from damage.

[0023] In this embodiment, as Figure 1 and Figure 3 As shown, both ends of the outer wall of the movable side plate 4 are provided with pointer-shaped structures that fit against the surface of the rear mounting plate 2, and the side of the rear mounting plate 2 corresponding to the pointer-shaped structure is marked with a scale. Through the cooperation of the pointer-shaped structure and the scale, it is ensured that the adjustment of the rubber layers on both sides is synchronous and symmetrical, so that the pressure applied to the fabric on both sides is evenly distributed, avoiding problems such as displacement and wrinkles of the fabric due to uneven pressure on both sides during the embroidery process.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the front mounting plates 1 are spaced a certain distance apart, and the surface of the front mounting plate 1 has a sloping structure. Mounting holes are provided at the lower edge of both the front mounting plate 1 and the rear mounting plate 2 on one side. The reserved gap between the front mounting plates 1 provides convenient operating space for the handle used to control the reverse lead screw 11 later. The hole structure on the surface of the front mounting plate 1 and the rear mounting plate 2 allows the device assembly to be easily fixed to the corresponding position on the embroidery machine through the mounting holes.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, the tension buckle 12 forms an elastic reset structure through a spring, and the movable side plate 4 and the adjacent end of the tension buckle 12 are both fixedly connected with a cylindrical structure for engaging the tension buckle 12. Whether clothing items are sleeved on the outside of the pressure plate 5 or a single layer of material is directly laid flat on the surface of the pressure plate 5, after the additional non-processed end of the material is placed on the surface of the fixed side plate 3, the movable side plate 4 is rotated to make it horizontal and fixed by engaging the tension buckle 12 with the cylindrical structure on the previous surface. This completes the initial fixing of the material. The elastic structure of the tension buckle 12 can provide a certain tension force to ensure the stability of the connection between the movable side plate 4 and the front mounting plate 1, and to ensure the continuity and stability of the embroidery process.

[0026] In this embodiment, as Figure 4 As shown, the first link 8 and the second link 9 are distributed in a V-shape, and one end of the first link 8 and the second link 9 are rotatably connected by a pin. The other end of the first link 8 and the second link 9 are rotatably connected to the bottom of their respective support plate 7 and the inner wall of the pressure plate 5. At the same time, the first link 8 and the second link 9 are located at both ends of the connecting seat 10 in pairs. When the connecting seat 10 moves under the drive of the reverse screw 11, the first link 8 and the second link 9 can accurately control the lifting and lowering of the support plate 7 due to the rotatable connection between the link and the support plate 7 and the pressure plate 5.

[0027] In this embodiment, as Figure 4 As shown, the first connecting rod 8 and the second connecting rod 9 are rotatably connected to the outer wall of the connecting seat 10 on their corresponding sides at the pin connection point. A handle is provided at the interval between the front mounting plates 1, which is rotatably connected to the outer wall of the pressure plate 5. The connecting seat 10 and the reverse screw 11 form a screw transmission structure. At the same time, the support plate 7 forms a lifting structure through the first connecting rod 8 and the second connecting rod 9. The lifting of the support plate 7 can achieve additional tension adjustment in its corresponding material area. Whether it is thin silk or thick denim, as well as materials with various complex shapes and textures, the tension can be adjusted by adjusting the support plate 7 to adapt to its characteristics. This provides precise local control for the embroidery process. Both the support plate 7 and the pressure plate 5 are solid structures, which have higher stability compared to hollow structures or other simple structures.

[0028] The method of use and advantages of this utility model: The embroidery pressing plate of this embroidery machine works as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the front mounting plate 1 and the rear mounting plate 2 are fixed to the designated positions on the embroidery machine frame using corresponding bolts or connectors through the mounting holes at the edges. During use, for single-layer, large-sized fabric, the fabric is laid flat directly on the surface of the pressure plate 5, with the extra untreated ends of the fabric placed on the surface of the fixed side plate 3. For double-layered materials such as clothing, the pressure plate 5 is flipped over, and the clothing is fitted over the outside of the pressure plate 5, with the extra untreated ends of the clothing placed on the fixed side plate 3. The movable side plate 4 is rotated to a horizontal position. At this time, the movable side plate 4 and the fixed side plate 3 press the fabric down from both sides, achieving initial fixation. The tension buckle 12 on the surface of the front mounting plate 1 engages with the cylindrical structure on the surface of the movable side plate 4 to ensure a stable connection between the movable side plate 4 and the front mounting plate 1. Depending on the thickness of the fabric or clothing component, the adjusting screw 6 is rotated. By rotating the adjusting screw 6, the bottom rubber layer of the movable side plate 4 can move up and down relative to the top rubber layer of the fixed side plate 3, achieving height adjustment to accommodate different materials. For materials of different thicknesses, appropriate pressure is provided. During the adjustment process, the operator can refer to the corresponding positions of the pointer-like structures at both ends of the outer wall of the movable side plate 4 and the scale on the surface of the rear mounting plate 2 to ensure that the adjustment of the rubber layers on both sides is synchronous and symmetrical. If the embroidery pattern requires adjustment of the tension of a local area of ​​the material, the handle connected to the outer wall of the pressure plate 5 is rotated through the gap between the front mounting plates 1. The rotation of the handle drives the reverse screw 11 to rotate, and the connecting seat 10 will move relative to the reverse screw 11. The movement of the connecting seat 10 will cause one end of the first connecting rod 8 and the second connecting rod 9 connected to it to be displaced, which will change the included angle between the first connecting rod 8 and the second connecting rod 9. When the included angle between the first connecting rod 8 and the second connecting rod 9 increases, the support plate 7 rises and lifts the fabric; when the included angle between the first connecting rod 8 and the second connecting rod 9 decreases, the support plate 7 falls. The support plate 7 makes vertical lifting and lowering movements through the first connecting rod 8 and the second connecting rod 9, thereby realizing the function of precise adjustment of the local tension of the material.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
