Description

Technical Field

[0001] This utility model relates to the field of embroidery processing technology, specifically a multi-station embroidery frame quick-switching clamping mechanism. Background Technology

[0002] Hand embroidery is a traditional craft that combines cultural heritage and artistic value, and is widely used in clothing decoration, home furnishings, and other fields. In the process of hand embroidery, the embroidery frame is one of the core auxiliary tools. Its main function is to flatten and fix the embroidery fabric, prevent the fabric from wrinkling or shifting during embroidery, help the embroiderer to more accurately control the direction of the stitches and the details of the pattern, and make the lines and colors of the embroidery work more coherent and beautiful, providing stable support for the creative process of hand embroidery.

[0003] Utility model patent CN216947448U discloses a portable Miao ethnic hand embroidery frame. This frame includes a support frame, with an adjustment mechanism mounted on one side. A square embroidery frame is rotatably connected to one side of the adjustment mechanism. The adjustment mechanism is used to adjust the position of the square embroidery frame. An anti-rotation mechanism is mounted at the top of the adjustment mechanism to limit the rotation of the square embroidery frame. The adjustment mechanism includes an extension frame, an output threaded rod, a driven bevel gear, a central shaft, and a driving bevel gear. This portable Miao ethnic hand embroidery frame, through the structural design of the adjustment mechanism, allows for convenient adjustment of the height of the square embroidery frame, thus meeting the needs of users of different heights and greatly improving its overall applicability. Furthermore, the structural cooperation between the square embroidery frame and the anti-rotation mechanism allows for convenient adjustment of the square embroidery frame angle while simultaneously achieving the adjusted anti-rotation limit, facilitating embroidery operations.

[0004] This Miao ethnic group's portable hand embroidery frame can only support a single embroidery frame and lacks a multi-station parallel structure. It can only process one piece of embroidery fabric at a time and cannot process multiple pieces of embroidery fabric alternately. When it is necessary to change the embroidery frame, the current processing flow must be paused, the old embroidery frame must be manually disassembled, and the new embroidery frame must be installed, resulting in a processing gap. In view of this, we propose a multi-station embroidery frame quick switching clamping mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station embroidery frame quick-switching clamping mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-station embroidery frame quick-switching clamping mechanism includes a base, a pair of uprights fixed to the top of the base, a first abutment fixed to the right side of the two uprights, a second abutment fixed to the left side of the two uprights, and a fixed shaft fixed between the tops of the two uprights. Several clamping mechanisms for clamping the embroidery frame are rotatably connected to the fixed shaft. Each embroidery frame corresponds to an independent clamping mechanism. By rotating the clamping mechanism around the fixed shaft, the clamping mechanism can be made to engage with the first abutment or the second abutment.

[0008] The clamping mechanism includes a rotating arm rotatably connected to a fixed shaft, a pair of fixed jaws fixed to the end of the rotating arm, and two movable jaws respectively sleeved on the bottom of the fixed jaws. The embroidery frame is clamped between the fixed jaws and the movable jaws. The top of the embroidery frame abuts against the end of the fixed jaws, and the bottom of the embroidery frame abuts against the end of the movable jaws.

[0009] Preferably, the first end of the rotating arm is fixed with a rotating sleeve with a hollow cylindrical structure. The rotating sleeve is sleeved on the outside of the fixed shaft and rotatably connected to the fixed shaft. Several retaining rings are sleeved and fixed on the fixed shaft, and the rotating sleeves of two adjacent clamping mechanisms are separated by retaining rings.

[0010] In this configuration, the rotating sleeve makes the clamping mechanism rotate more smoothly, and the retaining ring separates adjacent clamping mechanisms to prevent them from colliding with each other.

[0011] Preferably, the end of the fixed gripper has an L-shaped rod structure, and the bottom surface of the end of the fixed gripper is provided with a pair of first protrusions. The top of the embroidery frame is restricted between the two first protrusions. A connecting plate is fixed between the heads of the two fixed grippers, and the end of the rotating arm is fixedly connected to the end of the connecting plate.

[0012] In this setup, the L-shaped structure enhances the horizontal stability of the embroidery frame; the first protrusion limits the offset of the top of the embroidery frame, and the connecting plate ensures that the fixing claws are subjected to uniform force, making the connection more stable.

[0013] Preferably, the end of the movable gripper is an L-shaped rod structure, and the top surface of the end of the movable gripper is provided with a pair of second protrusions. The bottom end of the embroidery frame is restricted between the two second protrusions. The front end face of the fixed gripper is provided with a sleeve cavity. The front end of the movable gripper extends into the sleeve cavity and is slidably connected to the fixed gripper. A threaded rod is threadedly connected to the front end face of the movable gripper. The end of the threaded rod passes through the fixed gripper and is provided with a handle. By tightening the handle, the movable gripper can move upward along the sleeve cavity, thereby clamping the embroidery frame.

[0014] In this setup, the L-shaped structure works with the fixed gripper to wrap around the embroidery frame, the second protrusion restricts the bottom of the embroidery frame from shifting, the cavity ensures the movable gripper slides in a directional manner, and the threaded rod and the handle are adapted to embroidery frames of different thicknesses to maintain the clamping state.

[0015] Preferably, the top surface of the first support plate is horizontal, and a first support rod is fixed between the right end face of the top of the upright and the first support plate. When the clamping mechanism rotates around the fixed axis toward the first support plate, the rotating arm can be attached to the first support plate. At this time, the embroidery frame on the current clamping mechanism is in a state of waiting to be processed.

[0016] In this setup, the horizontal plane ensures that the embroidery frame is level for processing, facilitating embroidery. The first support rod enhances the strength of the first support plate to prevent deformation, and the overlapping method quickly positions the embroidery frame for processing.

[0017] Preferably, a plurality of first grooves are formed on the top surface of the first abutment along the length of the first abutment, the number of first grooves being equal to the number of clamping mechanisms and their positions corresponding one-to-one, and the rotating arm being able to engage with the first grooves.

[0018] In this setting, the first groove restricts the lateral sliding of the rotating arm to ensure that the embroidery frame is accurately positioned for processing.

[0019] Preferably, the top surface of the second abutment is inclined, and the angle between the top surface of the second abutment and the top surface of the first abutment is 150°. A second support rod is fixed between the left end face of the top of the upright and the second abutment. When the clamping mechanism rotates around the fixed axis toward the second abutment, the rotating arm can be attached to the second abutment. At this time, the embroidery frame on the current clamping mechanism is in the storage state.

[0020] In this setting, the 150° angle ensures that the storage unit and the embroidery frame to be processed do not interfere with each other, making it easy to identify the status; the sloping overlap ensures that the clamping mechanism is stable during storage.

[0021] Preferably, a plurality of second grooves are provided on the top surface of the second abutment along the length of the second abutment, the number of the second grooves being equal to the number of clamping mechanisms and their positions corresponding one-to-one, and the rotating arm being able to engage with the second grooves;

[0022] In this setting, the second groove restricts the lateral movement of the rotating arm, ensuring the stability of the embroidery frame storage.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This multi-station embroidery frame quick-switching clamping mechanism, through the cooperation of multiple clamping mechanisms and fixed shafts, can simultaneously carry multiple embroidery frames, forming a multi-station parallel processing structure. When the embroidery frame of one station is in the processing state, the embroidery frames of other stations can be clamped and positioned in advance. The embroidery frame can be switched by rotating around the shaft without pausing the processing flow, eliminating the processing gap period.

[0025] 2. This multi-station embroidery frame quick-switching clamping mechanism utilizes the partitioned design of the first and second support plates. The embroidery frame to be processed can be placed on the first support plate to maintain its waiting state, while the processed embroidery frame can be placed on the second support plate for storage. During switching, it is only necessary to rotate the clamping mechanism around the fixed axis and place it into the corresponding support plate's slot. No manual handling or recalibration is required, which reduces the number of operation steps while ensuring positioning accuracy, thus achieving rapid and stable switching of embroidery frames.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0036] Please see Figures 1-5The multi-station embroidery frame quick-switching clamping mechanism includes a base 100, which serves as the supporting foundation for the entire mechanism. A pair of uprights 110 are fixed to the top of the base 100, symmetrically distributed. A first abutment 120 is fixed to the right side of each upright 110, and a second abutment 130 is fixed to the left side. A fixed shaft 140 is fixed between the tops of the two uprights 110. Several clamping mechanisms 200 for holding embroidery frames 300 are rotatably connected to the fixed shaft 140. Each embroidery frame 300 independently corresponds to one clamping mechanism 200. This one-to-one correspondence ensures that each embroidery frame 300 can be clamped individually, and that the switching of each embroidery frame 300 does not interfere with each other, ensuring an orderly switching process. The fixed shaft 140 provides a rotation axis for the clamping mechanism 200, allowing the clamping mechanism 200 to rotate stably around it and providing a path for the workstation switching of the embroidery frame 300. The first abutment 120 and the second abutment 130 provide overlapping carriers for the clamping mechanism 200 in its processing and storage states, respectively, realizing the partitioned placement of the embroidery frame 300 in different states, making it easy for operators to distinguish them. The clamping mechanism 200 includes a rotating arm 210 rotatably connected to the fixed shaft 140, a pair of fixed jaws 220 fixed at the end of the rotating arm 210, and two movable jaws 230 respectively sleeved on the bottom end of the fixed jaws 220. The rotating arm 210 can drive the fixed jaws 220 and the movable jaws 230 to rotate synchronously around the fixed shaft 140. The fixed jaws 220 and the movable jaws 230 cooperate to clamp and release the embroidery frame 300, meeting the needs of fixing and disassembling the embroidery frame 300. By rotating the clamping mechanism 200 around the fixed shaft 140, the clamping mechanism 200 can be attached to the first abutment 120 or the second abutment 130. This rotation method does not require additional power components and can complete the workstation switching by manual operation, which is simple to operate and has low cost.

[0037] like Figure 1 and Figure 2As shown, in this invention, the top surface of the first abutment plate 120 is horizontal. This horizontal design ensures that the rotating arm 210 remains horizontal after being overlapped, thereby ensuring that the embroidery frame 300 is in a horizontal position ready for processing, facilitating accurate subsequent embroidery operations. A first support rod 111 is fixed between the right end face of the top of the upright rod 110 and the first abutment plate 120. The first support rod 111 enhances the connection strength between the first abutment plate 120 and the upright rod 110, preventing the first abutment plate 120 from deforming due to long-term bearing of the weight of the clamping mechanism 200, and extending the service life of the structure. When the clamping mechanism 200 rotates around the fixed axis 140 toward the first abutment plate 120, the rotating arm 210 can overlap the first abutment plate 120. At this time, the embroidery frame 300 on the clamping mechanism 200 is in a ready-to-process state. This overlap method can quickly position the embroidery frame 300 to be processed without the need for additional calibration tools, reducing operation steps. The top surface of the second abutment 130 is inclined, and the angle between the top surface of the second abutment 130 and the top surface of the first abutment 120 is 150°. The 150° angle design allows for a reasonable distance between the embroidery frame 300 in its stored state and the embroidery frame 300 in its unprocessed state, avoiding interference between the two during use and facilitating quick identification of the current state of the embroidery frame 300 by the operator. A second support rod 112 is fixed between the left end face of the top of the upright rod 110 and the second abutment 130. When the clamping mechanism 200 rotates around the fixed axis 140 toward the second abutment 130, the rotating arm 210 can overlap the second abutment 130. At this time, the embroidery frame 300 on the clamping mechanism 200 is in the stored state.

[0038] like Figure 1 and Figure 2 As shown, specifically, a plurality of first grooves 121 are formed on the top surface of the first abutment 120 along its length. The number of first grooves 121 is equal to the number of clamping mechanisms 200, and their positions correspond one-to-one. The rotating arm 210 can be inserted into the first groove 121. The first groove 121 can laterally limit the rotating arm 210, preventing it from sliding along its length on the first abutment 120, ensuring the accuracy of the position of the embroidery frame 300 to be processed, and improving the embroidery precision. A plurality of second grooves 131 are formed on the top surface of the second abutment 130 along its length. The number of second grooves 131 is equal to the number of clamping mechanisms 200, and their positions correspond one-to-one. The rotating arm 210 can be inserted into the second groove 131. The second grooves 131 have the same function as the first grooves 121, which can laterally limit the rotating arm 210 in the stored state, preventing the clamping mechanism 200 from shifting on the second abutment 130, and ensuring the stability of the stored state.

[0039] like Figures 1-3As shown, furthermore, a hollow cylindrical rotating sleeve 211 is fixed to the first end of the rotating arm 210. The rotating sleeve 211 is sleeved on the outside of the fixed shaft 140 and rotatably connected to the fixed shaft 140. The rotating sleeve 211 can increase the contact area between the rotating arm 210 and the fixed shaft 140, reduce the friction loss between the two, make the rotation of the clamping mechanism 200 smoother, and reduce the operating resistance. Several retaining rings 141 are sleeved and fixed on the fixed shaft 140. The rotating sleeves 211 of two adjacent clamping mechanisms 200 are separated by the retaining rings 141. The retaining rings 141 can physically separate adjacent clamping mechanisms 200, prevent the clamping mechanisms 200 from colliding or entangled with each other during rotation, and ensure that each clamping mechanism 200 can operate independently and stably.

[0040] like Figure 1 As shown, the embroidery frame 300 is clamped between the fixed clamp 220 and the movable clamp 230. The top of the embroidery frame 300 abuts against the end of the fixed clamp 220, and the bottom of the embroidery frame 300 abuts against the end of the movable clamp 230. Through the abutting cooperation of the upper and lower ends, the vertical movement of the embroidery frame 300 can be restricted, providing basic positioning support for the embroidery frame 300 and preventing the embroidery frame 300 from shifting up and down during the clamping process.

[0041] like Figure 3 and Figure 4 As shown, it is worth noting that the end of the fixing claw 220 has an L-shaped rod structure. The L-shaped structure can simultaneously provide an abutment surface and lateral restraint for the top of the embroidery frame 300, enhancing the horizontal stability of the embroidery frame 300 and preventing the embroidery frame 300 from tilting to the side. The bottom surface of the end of the fixing claw 220 is provided with a pair of first protrusions 221. The top of the embroidery frame 300 is restrained between the two first protrusions 221. The two first protrusions 221 can restrain the top of the embroidery frame 300 on the fixing claw 220, preventing the embroidery frame 300 from shifting along the end of the fixing claw 220 during processing and ensuring accurate embroidery positioning. A connecting plate 222 is fixed between the heads of the two fixed grippers 220. The end of the rotating arm 210 is fixedly connected to the end of the connecting plate 222. The connecting plate 222 can connect the two fixed grippers 220 into a whole, so that the fixed grippers 220 are subjected to uniform force, and at the same time achieve a stable connection between the rotating arm 210 and the fixed grippers 220, preventing the fixed grippers 220 from falling off.

[0042] like Figure 3 and Figure 5As shown, it is worth noting that the end of the movable gripper 230 has an L-shaped rod structure, which cooperates with the L-shaped structure of the fixed gripper 220 to form a complete wrapping and limiting of the embroidery frame 300 from the bottom, further improving the clamping stability of the embroidery frame 300 and preventing the embroidery frame 300 from loosening during processing. The top surface of the end of the movable gripper 230 is provided with a pair of second protrusions 231. The bottom end of the embroidery frame 300 is restricted between the two second protrusions 231. The two second protrusions 231 correspond vertically to the first protrusion 221, so that the second protrusions 231 and the first protrusion 221 work together to prevent the embroidery frame 300 from shifting, thereby improving the overall positioning accuracy. The fixed gripper 220 has a cavity 223 in the front end face. The front end of the movable gripper 230 extends into the cavity 223 and is slidably connected to the fixed gripper 220. The cavity 223 provides a directional sliding track for the movable gripper 230, ensuring that the movable gripper 230 moves only in the vertical direction, avoiding deviation when the movable gripper 230 slides, and ensuring accurate clamping action. The movable gripper 230 has a threaded rod 232 threadedly connected to its first end face. The end of the threaded rod 232 passes through the fixed gripper 220 and is provided with a handle 2321. By tightening the handle 2321, the movable gripper 230 can move upward along the sleeve cavity 223, thereby clamping the embroidery frame 300. The threaded rod 232 and the handle 2321 cooperate to form a manual adjustment structure. The operator can precisely control the rising distance of the movable gripper 230 by rotating the handle 2321 to adapt to embroidery frames 300 of different thicknesses. At the same time, the threaded connection has a self-locking characteristic, which can maintain the clamping state of the movable gripper 230 and prevent the embroidery frame 300 from loosening during processing.

[0043] In this embodiment, the multi-station embroidery frame quick-switching clamping mechanism is used as follows: First, the embroidery frame 300 to be processed is placed between the fixed clamp 220 and the movable clamp 230, so that the top end of the embroidery frame 300 abuts against the end of the fixed clamp 220 and the bottom end abuts against the end of the movable clamp 230. The top end of the embroidery frame 300 is positioned between two first protrusions 221 and the bottom end is positioned between two second protrusions 231, completing the initial positioning of the embroidery frame 300. Then, rotating the handle 2321 drives the threaded rod 232 to rotate. Utilizing the threaded connection between the threaded rod 232 and the movable clamp 230, the movable clamp 230 slides upward along the cavity 223 until the movable clamp 230 and the fixed clamp 220 together clamp the embroidery frame 300, completing the clamping and fixing of a single embroidery frame 300. This step is repeated to clamp other embroidery frames 300 on the corresponding clamping mechanism 200. Next, by manually moving the clamping mechanism 200, the clamping mechanism 200 is rotated around the fixed clamp 220. The rotating sleeve 211 on the fixed shaft 140 rotates, and the rotating arm 210 of the clamping mechanism 200, which holds the embroidery frame 300 to be processed, is placed into the first groove 121 of the first abutment plate 120. At this time, the embroidery frame 300 enters the processing state. At the same time, the rotating arm 210 of the clamping mechanism 200, which holds the processed embroidery frame 300, is placed into the second groove 131 of the second abutment plate 130. The embroidery frame 300 enters the storage state. Adjacent clamping mechanisms 200 are separated by retaining rings 141 to avoid mutual interference. Finally, when the embroidery frame 300 in the processing state is processed, the clamping mechanism 200 is rotated around the fixed shaft 140 again, and the processed embroidery frame 300 is switched with the clamping mechanism 200 to the second groove 131 of the second abutment plate 130 for storage. At the same time, the next embroidery frame 300 to be processed is switched with the clamping mechanism 200 to the first groove 121 of the first abutment plate 120 for processing, realizing the rapid switching of the embroidery frame 300.
