Description

Technical Field

[0001] This application relates to the field of embroidery, and more particularly to an embroidery positioning clamp with multi-angle adjustable angle. Background Technology

[0002] Embroidery is a traditional handicraft that uses needle and thread to stitch patterns onto fabric. Embroidery is a craft that uses needles as pens and threads as ink to sew patterns onto fabrics such as cloth and silk.

[0003] Traditional embroidery first selects a suitable fabric (silk, cotton, brocade, etc.) as the base material, requiring it to be flat, strong, and not prone to pilling. The embroidery thread is usually silk thread, but sometimes gold and silver thread, cotton thread, wool thread, etc. are also used. Then, an embroidery needle is used to embroider.

[0004] Before embroidering, stretch the fabric taut on an embroidery hoop or large embroidery frame to keep the embroidery surface flat and wrinkle-free. Use techniques such as flat stitch, gold thread embroidery, seed stitch, satin stitch, pick stitch, and chain stitch to embroider. After finishing the embroidery, trim off any excess thread and clean the reverse side to complete the embroidery work.

[0005] Traditional embroidery requires manual tension and fixation, with the angle of the needle constantly adjusted during the embroidery process to complete the work. However, different stitches, line directions, and pattern layers all demand precise control of the needle's angle into the fabric. Even minute changes in angle directly affect the tightness, sheen, and three-dimensionality of the stitches. This is especially true when depicting the curves of petals, the layers of feathers, or the expressions of figures, requiring constant adjustments to hand movements and the embroidery angle to achieve delicate and lifelike effects. This mastery of angle not only relies on experience but also reflects the embroiderer's artistic cultivation and profound craftsmanship.

[0006] The process of embroidery requires holding the fabric and constantly changing its angle, which makes the worker's hands very tired and prone to fatigue. If fatigue occurs, the embroidery may be damaged or defective, thus affecting the finished product. Utility Model Content

[0052] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0053] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0054] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] Embodiments of this application provide a multi-angle adjustable embroidery positioning clamp 100, comprising:

[0056] The fixed bracket 110 is provided with a rotating part 111, and the rotating part 111 is provided with a rotating groove 111a;

[0057] A rotating component 120 is arranged around the rotating part 111 and located in the rotating groove 111a. The rotating component 120 is rotatably connected to the rotating part 111.

[0058] The locking member 130 has one end passing through the rotating member 120 and the other end abutting against the rotating part 111 to fix the rotating member 120.

[0059] The positioning clamp assembly 140 is disposed on the rotating member 120.

[0060] Please refer to Figures 1-4 In this embodiment, the user places the embroidered fabric in the positioning clamp assembly 140. The positioning clamp provides clamping force, forming a clamping space 140a and reliably fixing the fabric. The user can adjust the angle of the positioning clamp assembly 140 by rotating the rotating component 120. Since the rotating component 120 is disposed in the rotating groove 111a and rotatably connected to the rotating part 111, its rotation angle is stable and controllable. After adjusting to the ideal angle, the rotating component 120 is locked relative to the rotating part 111 by tightening the locking component 130, thereby achieving precise and stable maintenance of the embroidery angle of the fabric.

[0061] Workers no longer need to frequently rotate the fabric by hand; they only need to adjust the angle appropriately in the clamp. By replacing hand movements with clamps, mechanical assistance is achieved, significantly reducing the physical burden on embroiderers.

[0062] The structure of the rotating part 120 and the rotating groove 111a allows for 360° adjustment of the fabric angle. With the locking part 130, the angle is fixed and reliable, preventing the embroidery quality from being affected by angle deviation.

[0063] Multi-angle adjustment makes it easier for embroiderers to find the most suitable needle insertion angle, reducing defective products caused by fatigue or improper angle control, and enhancing product consistency.

[0064] It should be noted that the fixed bracket 110 is roughly a ring-shaped frame, the rotating part 111 is ring-shaped and forms a stepped ring, and the rotating groove 111a is a ring-shaped groove structure; the rotating part 120 is roughly ring-shaped; and the locking part 130 is a bolt or locking screw.

[0065] In at least one embodiment of this application, a clamping space 140a is formed between the positioning clamping assemblies 140;

[0066] An open slot 111b is provided at the geometric center of the rotating part 111, and the open slot 111b is connected to the clamping space 140a.

[0067] Please refer to Figures 1-4 In this embodiment, when installing the fabric, the user places the fabric into the clamping space 140a. With the subsequent clamping mechanism, the clamp firmly presses and fixes the fabric, forming a stable embroidery support platform during the embroidery process.

[0068] An open slot 111b is formed at the geometric center of the rotating part 111 and is connected to the clamping space 140a. The fabric usually needs to be centered and aligned. The open slot 111b allows the fabric to pass through the central area of ​​the rotating part 111 from the clamping space 140a, which is convenient for centered arrangement and wire threading.

[0069] When the positioning clamp assembly 140 rotates with the rotating component 120, the open slot 111b reserves rotation space for the movement and position adjustment of the fabric, preventing structural interference.

[0070] During the embroidery process, the embroiderer needs to observe the front and back of the fabric and check the stitches. The open slot 111b forms a viewing window or a manual adjustment channel.

[0071] Because the clamping space 140a is open and connected to the center of the rotating part 111, the fabric is no longer limited to a single size or direction. Whether it is a small pattern embroidery or a large piece of fabric, it can be fixed by the center-threading method.

[0072] With precise fabric placement and multi-angle adjustments, continuous multi-angle embroidery can be performed without loosening the fabric, reducing the need for repeated fabric disassembly and assembly, improving efficiency, and lowering the risk of defects.

[0073] It should be noted that the open slot 111b is a through slot and is opened along the axis of the rotating part 111 at the center of the rotating part 111.

[0074] In at least one embodiment of this application, the rotating member 120 is provided with a positioning hole 120a, one end of the locking member 130 abuts against the rotating member 120, and the other end extends through the positioning hole 120a into the rotating groove 111a and abuts against the rotating part 111.

[0075] Please refer to Figures 1-4 In this embodiment, the rotating member 120 is fitted on the outside of the rotating part 111. By rotating together with the positioning clamp assembly 140, the angle of the fabric is changed. At this time, the locking member 130 is in a loose state, allowing the rotating member 120 to rotate.

[0076] The user manually rotates the rotating component 120, causing the positioning clamp assembly 140 to rotate to the required angle. During the rotation process, the rotation groove 111a restricts its movement trajectory to ensure smooth rotation.

[0077] After being rotated to the target angle, the locking member 130 is tightened. One end of the locking member 130 is pressed against the surface of the rotating member 120, passes through the positioning hole 120a and enters the rotating groove 111a, and abuts against the rotating part 111 below. This structure forms a three-point clamping: from the rotating member 120 to the locking member 130 to the rotating part 111, thus achieving a firm lock.

[0078] The entire rotating component 120 is mechanically constrained and can no longer rotate freely. The positioning clamp assembly 140 is then in a stable angle state for subsequent embroidery operations.

[0079] Through the structural cooperation of the positioning hole 120a and the rotating groove 111a, the locking member 130 not only prevents the rotating member 120 from slipping, but also forms a mechanical cooperation of positioning and locking, ensuring that there is no loosening or slippage after the angle is locked, thus improving the stability of the fixture.

[0080] After locking, the structure has good rigidity, which avoids problems such as pattern displacement and uneven stitches caused by fabric displacement during embroidery, improves product consistency and reduces scrap rate.

[0081] By using the surrounding structure design of the rotating component 120 and the variable positioning of the locking component 130 within the rotating groove 111a, multiple angles can be precisely selected to meet the needs of different patterns and embroidery techniques for needle insertion angles, such as when depicting three-dimensional textures like petals and feathers.

[0082] It should be noted that the positioning hole 120a is a through hole and a screw hole.

[0083] In at least one embodiment of this application, the positioning clamp assembly 140 includes:

[0084] The fixing plate 141 is fixed to the rotating component 120;

[0085] The drive assembly 142 is mounted on the fixing plate 141 at one end;

[0086] Rotating component 143 is rotatably mounted on the fixed plate 141 and is connected to the other end of the driving component 142 in a transmission manner.

[0087] The clamping assembly 144 is mounted on the rotating assembly 143 and has a clamping position 144a.

[0088] Please refer to Figures 1-4In this embodiment, the user places the fabric into the clamping position 144a of the clamping component 144, adjusts the position, and starts the drive component 142. The drive component 142 drives the rotating component 143 to move, causing the clamping component 144 to clamp or release. The fabric is firmly fixed in the clamping position 144a, which is convenient for embroidery. Since the entire clamping structure is integrated with the rotating component 120, the embroidery angle can be further adjusted by the rotating component 120. In the stable clamping state, the embroidery worker does not need to hold the fabric and can slightly adjust the angle through the drive control to adapt to different embroidery requirements.

[0089] In this structure, a complete automatic clamping and releasing system is formed by a drive component 142, a rotating component 143, and a clamping component 144, which can ensure that each clamping is uniform and stable and reduce human error.

[0090] The rotating component 143 can achieve multiple angle changes in the clamping direction. Combined with the angle adjustment of the rotating component 120, it can achieve dual-layer angle control (main clamp + fine adjustment of clamping component 144) and improve the ability to control the details of embroidery.

[0091] Automatic clamping significantly reduces manual operation, improves the comfort of the embroidery process, and avoids a decline in craftsmanship due to hand fatigue.

[0092] Please refer to Figures 1-4 In this embodiment, the fixing plate 141 is generally a vertical plate.

[0093] In at least one embodiment of this application, the clamping assembly 144 includes:

[0094] The first driving member 1441 is rotatably mounted on the rotating assembly 143;

[0095] The first clamping arm 1442 has one end rotatably connected to the output end of the first driving member 1441; the other end is provided with a first clamping part 1443, and the first clamping arm 1442 is rotatably connected to the rotating assembly 143.

[0096] The second clamping arm 1444 has one end fixed to the rotating assembly 143 and the other end provided with a second clamping part 1445. The clamping position 144a is formed between the first clamping part 1443 and the second clamping part 1445.

[0097] Please refer to Figures 1-4 In this embodiment, during the initialization phase: the first clamping arm 1442 is in an open state, and a clamping space 140a is formed between the first clamping part 1443 and the second clamping part 1445. The fabric is placed at the clamping position 144a by the embroiderer.

[0098] The first drive unit 1441 is activated, and the first drive unit 1441 outputs rotation, causing the first clamping arm 1442 to swing and move closer to the second clamping arm 1444.

[0099] The first clamping part 1443 and the second clamping part 1445 gradually close. When the first clamping part 1443 and the second clamping part 1445 are in contact or adhere to each other, the fabric is clamped and the fabric is firmly fixed.

[0100] Embroidery can be done while the fabric is stable. If the angle or fabric needs to be changed, the drive unit reverses its movement, and the first clamping arm 1442 opens to release the fabric.

[0101] The first clamping arm 1442 is actively driven by the first driving component 1441, and the clamping force and position can be set according to the fabric thickness, softness and tension requirements, making it more adaptable.

[0102] The first clamping arm 1442 is movable, while the second clamping arm 1444 is fixed, forming a movable and static clamping structure, which improves the reliability of clamping and prevents the fabric from loosening, slipping, or misaligning during the embroidery process.

[0103] It should be noted that the first driving component 1441 is a hydraulic cylinder or a pneumatic cylinder. The first clamping arm 1442 is approximately an "L"-shaped clamping arm, and the second clamping arm 1444 is approximately a "U"-shaped clamping arm, with part of the first clamping arm 1442 located inside the second clamping arm 1444.

[0104] Both the first clamping part 1443 and the second clamping part 1445 are clamping plates.

[0105] In at least one embodiment of this application, a first mounting hole is provided on the first clamping part 1443, and a second mounting hole is provided on the second clamping part 1445.

[0106] The clamping assembly 144 further includes:

[0107] A wear-resistant deformable ball 1446 is installed in the first mounting hole;

[0108] The wear-resistant positioning post 1447 has one end installed in the second mounting hole and the other end has a deformation abutment surface 1447a, which is arranged opposite to the wear-resistant deformation ball 1446.

[0109] Please refer to Figures 1-4 In this embodiment, the first clamping part 1443 and the second clamping part 1445 are located at the ends of the first clamping arm 1442 and the second clamping arm 1444, respectively, and are opposite to each other to form a clamping position 144a of the fabric.

[0110] The first mounting hole and the second mounting hole are respectively opened on the first clamping part 1443 and the second clamping part 1445. The wear-resistant deformation ball 1446 is installed in the first mounting hole. The wear-resistant deformation ball 1446 has good wear resistance and a certain elasticity. When the clamping assembly 144 is closed, the wear-resistant deformation ball 1446 contacts the deformation contact surface 1447a. It can deform slightly to form a uniform and stable contact force distribution, buffer the clamping impact and protect the fabric from being crushed.

[0111] When the clamping assembly 144 is closed, the wear-resistant deformable ball 1446 abuts against the deformable contact surface 1447a. The contact point absorbs the instantaneous impact of the clamping force and then fits firmly to form a clamping support point, ensuring that the first clamping arm 1442 and the second clamping arm 1444 are accurately aligned when closed.

[0112] The wear-resistant deformable ball 1446 and the deformable contact surface 1447a provide flexible cushioning at the moment of closure, resulting in more even force distribution. This is suitable for delicate fabrics and avoids fabric creases, indentations, or even perforations caused by traditional rigid clamps.

[0113] The wear-resistant deformation ball 1446 and the deformation contact surface 1447a have the ability to fine-tune self-alignment when clamped. The alignment can be finely adjusted by sliding the ball surface to keep the fabric in an accurate position.

[0114] It should be noted that both the first and second mounting holes are circular. The wear-resistant deformation ball 1446 is a sphere made of rubber material, and the wear-resistant positioning post 1447 is roughly cylindrical, with one end (deformation contact surface 1447a) being hemispherical and made of rubber material.

[0115] In at least one embodiment of this application, the wear-resistant deformable balls 1446 are in multiple groups, and the diameter of each group of wear-resistant deformable balls 1446 is different.

[0116] Please refer to Figures 1-4 In this embodiment, when the clamping assembly 144 is closed, the wear-resistant deformable ball 1446 contacts the wear-resistant positioning post 1447 on the opposite side. The smaller diameter ball provides a delicate and soft contact, suitable for thin fabrics and fine embroidery patterns, while the larger diameter ball provides stronger support, suitable for thick fabrics or larger patterns. If it is necessary to change the embroidery fabric or adjust the clamping state, it can be replaced with a group of deformable balls of other diameters. The design of multiple groups of deformable balls of different diameters allows the equipment to be precisely adjusted according to the type, thickness, and texture requirements of the fabric, no longer limited to a single type of fabric, expanding the range of applications of the clamp and making it highly adaptable.

[0117] Reduce the area of ​​pressure points, buffer concentrated pressure, and avoid creases or indentations on the embroidery surface.

[0118] In at least one embodiment of this application, the driving component 142 includes:

[0119] The second driving component 1421 is fixed at one end to the fixing plate 141;

[0120] The first rotation linkage shaft 1422 has one end located at the output end of the second drive member 1421, and the other end rotatably connected to the rotation assembly 143.

[0121] Please refer to Figures 1-4 In this embodiment, the second driving member 1421 is fixed on the fixed plate 141, and the first rotating linkage shaft 1422 is connected between the driving member and the rotating assembly 143, and is in a rotatable connection state.

[0122] When the embroiderer or system controller starts the second drive unit 1421, its output shaft begins to rotate, and the first rotation linkage shaft 1422 transmits the rotational power to the rotation assembly 143.

[0123] After receiving the rotational force, the rotating component 143 generates a preset action, such as rotating the clamp angle, driving the clamping component 144 to open and close, and adjusting the embroidery direction.

[0124] After the action is completed, the drive component 142 can stop or reverse to realize the clamp angle restoration or release action.

[0125] It can automatically adjust the angle and clamping status according to the embroidery pattern, significantly improving the efficiency of continuous operation. It eliminates the need for repeated manual adjustment of the clamp position, reduces the decline in embroidery quality caused by fatigue, and improves the consistency and precision of each embroidery piece.

[0126] It should be noted that the second drive component 1421 is generally a pneumatic cylinder or a hydraulic cylinder, and the first rotating linkage shaft 1422 is a ball cage universal coupling.

[0127] In at least one embodiment of this application, the rotating assembly 143 includes:

[0128] Rotary connector 1431, one end of which is rotatably connected to the fixed plate 141;

[0129] The connecting plate 1432 has a first rotating position 1432a, a second rotating position 1432b, and a mounting position 1432c. The connecting plate 1432 is fixedly connected to the rotating connecting member 1431. The first rotating position 1432a is rotatably connected to the first rotating linkage shaft 1422. The mounting position 1432c is fixedly connected to the first driving member 1441. The second rotating position 1432b is rotatably connected to the first clamping arm 1442.

[0130] Please refer to Figures 1-4In this embodiment, the rotating connector 1431 is mounted on the fixed plate 141 by means of bearings or the like and can rotate. The connecting plate 1432 is fixed on the rotating connector 1431 to form an overall swing structure. The first rotating linkage shaft 1422 is connected at the first rotating position 1432a.

[0131] The first drive component 1441 is mounted on the connecting plate 1432 and connected to the first clamping arm 1442. Through the second rotation position 1432b on the connecting plate 1432, the first clamping arm 1442 is flexibly rotated and connected to the drive output.

[0132] When the first drive unit 1441 is activated, its output end drives the first clamping arm 1442 to rotate. The first clamping arm 1442 moves toward the second clamping arm 1444, so that the first clamping part 1443 gradually approaches the second clamping part 1445 and clamps the fabric. The connecting plate 1432 can rotate as a whole with the rotating connecting unit 1431, so that the clamp angle is adjustable to further adjust the angle of the fabric.

[0133] It should be noted that the rotating connector 1431 is a connector with a bearing at one end and a plate-shaped connector at the other end; the connecting plate 1432 is roughly a rectangular plate, and the first rotating position 1432a and the second rotating position 1432b are equipped with bearings.

[0134] In at least one embodiment of this application, the clamping assembly 144 further includes:

[0135] The second rotating linkage shaft 1448 is rotatably connected at both ends to the first driving member 1441 and the first clamping arm 1442, respectively.

[0136] Please refer to Figures 1-4 In this embodiment, when the first driving component 1441 (which may be a telescopic cylinder or a hydraulic cylinder) is activated, its output shaft rotates. The rotation action is transmitted to the first clamping arm 1442 through the second rotation linkage shaft 1448, so as to realize the precise rotation of the first clamping arm 1442, thereby driving the clamp to perform clamping or opening actions.

[0137] The second rotation linkage shaft 1448 itself has rotational freedom, which allows for continuous power transmission even when the clamping assembly 144 itself has slight displacement or angle adjustment, ensuring stable opening and closing of the clamping arm in a multi-angle clamping environment.

[0138] The second rotating linkage shaft 1448 serves as a bridge connecting the first driving component 1441 and the clamping arm, making the power transmission path more flexible, ensuring consistency in each clamping opening and closing, and facilitating embroidery quality control.

[0139] The second rotation linkage shaft 1448 allows for effective transmission of driving force even when the clamping assembly 144 rotates or tilts, solving the problem that traditional rigid linkage transmission cannot adapt to changes in posture.

[0140] It should be noted that the second rotating linkage shaft 1448 is a ball cage universal coupling.

[0141] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
