Description

Technical Field

[0001] This application relates to the field of embroidery machines, and more particularly to a small embroidery machine. Background Technology

[0002] An embroidery machine is a machine specifically designed for embroidery. It is characterized by its speed, efficiency, and high quality, and is now widely used in the modern textile industry.

[0003] Currently, Chinese utility model patent CN210031112U discloses a lightweight single-head flat embroidery machine, including a frame, a machine head, a color-changing mechanism, a flat embroidery shuttle box equipped with a thread-cutting mechanism, and an embroidery frame moving mechanism. The frame includes two opposing supports, at least two crossbeams, and at least two bottom beams. The supports consist of an upper cross arm, a column, and a lower cross arm connected in sequence to form a C-shaped structure. The crossbeams are located between the upper cross arms of the two supports, and the bottom beams are located between the lower cross arms of the two supports. The embroidery frame moving mechanism is suspended below the at least two cross beams. The shuttle box is located on one of the bottom beams. The machine head and color-changing mechanism are located on a cross beam above the shuttle box. A needle bar frame is located in front of the machine head. The color-changing mechanism drives the needle bar frame to move and switch different needle bars to the top of the shuttle box to complete the color change. This utility model improves embroidery precision and is suitable for personalized embroidery with pattern making.

[0004] Embroidery machines can not only embroider fabrics, but also the surfaces of pre-shaped items such as bags. Before embroidering, the item to be embroidered needs to be fixed on the embroidery frame. The embroidery pattern on the pre-shaped item has high requirements for position and direction. The relative position of the item to be embroidered and the machine head can be adjusted by moving the embroidery frame horizontally. However, the relative direction of the item to be embroidered and the machine head requires the operator to remove the item from the embroidery frame multiple times, which takes a long time. Summary of the Invention

[0005] To reduce the time workers spend adjusting the angle of the embroidery on the embroidery frame, this application provides a small embroidery machine.

[0006] This application provides a small embroidery machine, which adopts the following technical solution:

[0007] A small embroidery machine includes an embroidery machine body, an embroidery frame, a rotating frame, a magnetic frame, and a driving component. The embroidery frame is mounted on the embroidery machine body. The rotating frame is annular and rotatably connected to the embroidery frame along its axial direction. The magnetic frame is annular and the rotating frame can be used to attract the magnetic frame. The object to be embroidered is clamped by the magnetic frame and the rotating frame. The driving component is used to drive the rotating frame to rotate relative to the embroidery frame.

[0008] By adopting the above technical solution, the staff first lays the object to be embroidered flat on the rotating frame, and places the magnetic frame on the side of the object to be embroidered away from the rotating frame. The rotating frame attracts the magnetic frame, and the magnetic frame and the rotating frame clamp the object to be embroidered. Then, the staff can drive the rotating frame to rotate through the drive component, which makes it easy for the staff to adjust the angle of the object to be embroidered relative to the machine head, reducing the need for the object to be embroidered to repeatedly detach from the embroidery frame, greatly reducing adjustment time and improving work efficiency.

[0009] Optionally, the driving component includes a gear ring, a gear, and a drive motor. The gear ring is coaxial with the rotating frame and is disposed on the rotating frame. The gear is disposed on the rotating frame and meshes with the gear ring. The drive motor is used to drive the gear to rotate.

[0010] By adopting the above technical solution, when the worker needs to rotate the object to be repaired, he starts the drive motor. The drive motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the rotating frame to rotate relative to the embroidery frame. Since the magnetic frame and the rotating frame clamp the object to be embroidered, the object to be embroidered and the magnetic frame rotate simultaneously when the rotating frame rotates. The angle of the object to be embroidered relative to the machine head is adjusted. Since the object to be repaired will cover the rotating frame, the drive component can easily drive the rotation of the rotating frame to achieve the angle adjustment of the object to be embroidered relative to the machine head.

[0011] Optionally, the driving component further includes a worm gear and a worm, the worm gear being coaxial with the gear and mounted on the gear, the worm being rotatably connected to the embroidery frame and meshing with the worm gear, and the output shaft of the drive motor being connected to the worm.

[0012] By adopting the above technical solution, when the workpiece to be embroidered needs to rotate, the drive motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the rotating frame to rotate. The magnetic frame and the rotating frame clamp the workpiece to be embroidered. When the rotating frame rotates, the workpiece to be embroidered and the magnetic frame rotate simultaneously. The worm gear has high transmission precision, and the rotating frame rotates smoothly, resulting in high adjustment precision of the workpiece to be embroidered relative to the machine head. The worm gear has a self-locking effect, so the rotating frame will not rotate when touched by external force, thus improving the effect of the drive components.

[0013] Optionally, the magnetic frame includes a magnetic ring and several tensioning components. The tensioning components are evenly distributed circumferentially along the axis of the magnetic ring. Each tensioning component includes a transmission belt, two transmission rollers, several needles, and a limiting member. The length direction of the transmission belt is parallel to the radial direction of the magnetic ring. The two transmission rollers are distributed along the length direction of the transmission belt. The transmission rollers are rotatably connected to the magnetic ring. The transmission belt is sleeved on the transmission rollers. The several needles are disposed on the transmission belt. The limiting member is used to restrict the needles from moving towards the axis of the magnetic ring.

[0014] By adopting the above technical solution, the magnetic ring is attracted by the rotating frame, and the magnetic ring and the rotating frame clamp the object to be embroidered. At this time, the needle on the transmission belt pierces the object to be embroidered. The object to be embroidered needs to be kept taut during the embroidery process. The worker can drive the transmission belt to rotate, and the transmission belt drives the needle groove to move away from the axis of the magnetic ring, so that the object to be embroidered is taut. The limiting component restricts the needle from moving towards the axis of the magnetic ring. The tensioning component keeps the object to be repaired taut, thus improving the embroidery quality.

[0015] Optionally, the limiting component includes a ratchet, a pawl, a limiting spring, and a lever. The ratchet is disposed on one end of one of the transmission rollers. The pawl is rotatably connected to the magnetic ring and is used to engage with the ratchet. The limiting spring is used to keep the pawl engaged with the ratchet. The lever is disposed on the pawl.

[0016] By adopting the above technical solution, when the worker rotates the conveyor belt, the belt causes the needle to move away from the axis of the magnetic ring, keeping the embroidered object taut. The conveyor belt also drives the transmission roller to rotate, which in turn drives the ratchet to rotate. At this time, the pawl cannot remain engaged with the ratchet. When the embroidered object is taut, the pawl is engaged with the ratchet by the limiting spring, preventing the transmission roller from rotating and the conveyor belt from driving the needle to move towards the axis of the magnetic ring. After the embroidery is completed, the worker first rotates the lever, which causes the pawl to overcome the elasticity of the limiting spring and stay away from the ratchet. When the embroidered object is relaxed from a taut state, it drives the needle on the conveyor belt to move towards the axis of the magnetic ring. Then, the worker can detach the needle from the magnetic ring. The limiting structure is simple and reasonable, making it easy for workers to operate.

[0017] Optionally, the magnetic ring further includes an unlocking component, which includes an unlocking ring, a plurality of unlocking blocks, and an unlocking spring. The unlocking ring is slidably connected to the magnetic ring along the axial direction of the magnetic ring. The plurality of unlocking blocks correspond one-to-one with a plurality of limiting components. The unlocking blocks are disposed on the unlocking ring. The unlocking blocks have a guide slope for guiding the rotation of the lever and keeping the ratchet away from the pawl. The unlocking spring is used to keep the unlocking blocks away from the lever.

[0018] By adopting the above technical solution, since there are several tensioning components on the magnetic ring, the operator can simultaneously operate the limiting components of multiple tensioning components through the unlocking device. The operator overcomes the elasticity of the unlocking spring and moves the unlocking ring towards the magnetic frame. As the guide slope on the unlocking block abuts against the lever, the lever overcomes the elasticity of the limiting spring and rotates away from the ratchet. The transmission belt, which is now in a free state, relaxes the embroidered material that was originally in a taut state. The embroidered material moves through the needle, allowing the subsequent embroidered material to detach from the needle. Once the needle detaches from the embroidered material, the operator can release the unlocking ring. The unlocking ring moves under the elasticity of the unlocking spring, keeping the unlocking block away from the lever. The unlocking device has a simple structure, making it easy for the operator to control multiple tensioning components simultaneously.

[0019] Optionally, the magnetic ring further includes a driving component, which includes a driving ring and a plurality of driving columns. Each of the driving columns corresponds to a plurality of tensioning components. The driving columns are disposed on the transmission belt. The driving ring and the magnetic ring are coaxially disposed. The driving ring is rotatably connected to the magnetic ring. The driving ring is provided with a plurality of sliding grooves, each of the sliding grooves corresponding to a plurality of driving columns. The sliding grooves are straight. The distance from one end of the sliding groove to the axis of the magnetic ring is greater than the distance from the other end of the sliding groove to the axis of the magnetic ring. The driving columns are located within the sliding grooves.

[0020] By adopting the above technical solution, since there are several tensioning components, the operator can control these components through a drive mechanism. The distances from the two ends of the sliding groove to the axis of the drive ring are different, and the sliding groove is linear. Therefore, when the embroidery needs to be tightened, the operator can rotate the drive ring. The sliding groove on the rotating ring will cause the distance between the sliding column and the axis of the drive ring to change. The sliding column drives the transmission belt to move, and the transmission belt drives the needle to move. The needle keeps the embroidery in a taut state, and the limiting component restricts the needle from moving in the direction of the axis of the rotating ring. The drive mechanism makes it easy for the operator to tighten the embroidery with several tensioning components, and the mechanism is reasonable and easy for the operator to operate.

[0021] Optionally, the rotating frame is provided with a plurality of mating parts, each of which corresponds one-to-one with a plurality of tensioning components. Each mating part includes a sliding block, which slides along the radial direction of the rotating frame and is connected to the rotating frame. The needle is used to pierce the sliding block.

[0022] By adopting the above technical solution, when the magnetic frame and the rotating frame hold the object to be embroidered, the needle penetrates the object and pierces the sliding block, so that the needle can completely penetrate the object. The sliding block reduces the wear of the needle and can move with the needle on the transmission belt. The sliding block has a reasonable structure and extends the service life of the needle.

[0023] Optionally, the mating component further includes a spring sheet, one end of which is disposed on the rotating frame. The spring sheet is used to abut against the sliding block, and when the object to be embroidered is in a taut state, the spring sheet has elastic potential energy.

[0024] By adopting the above technical solution, when the embroidered item needs to be removed from the embroidery frame, the worker first moves the unlocking ring. The unlocking ring overcomes the elasticity of the unlocking spring, and the guide slope of the unlocking block drives the lever to rotate. The lever drives the pawl to overcome the elasticity of the limiting spring and disengage from the ratchet. The transmission roller is in a free state, and the tensioned spring will drive the sliding block to move. The sliding block cooperates with the spike to relax the embroidered item, making it easier for the magnetic frame to disengage from the rotating frame. Then, the embroidered item is removed from the needle. The position of the sliding block remains unchanged due to the elasticity of the spring, making it easy for the needle to align with the sliding block when the magnetic frame is installed later.

[0025] Optionally, the embroidery machine body is also provided with a support platform for receiving the embroidery work, and the support platform is connected to the embroidery machine body by bolts.

[0026] By adopting the above technical solution, the support platform is used to support the fabric to be embroidered. The support platform is connected to the embroidery machine body by bolts. When the embroidery machine body needs to embroider the fabric with an existing shape, the support platform can be removed from the embroidery machine body to provide space for the fabric with an existing shape to move.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The rotating frame is rotatably connected to the embroidery frame and holds the embroidery workpiece through the magnetic frame. The embroidery workpiece can rotate along the axis of the rotating frame, realizing the adjustment of the angle between the embroidery workpiece and the machine head;

[0029] 2. The tensioning component is used to tighten the material to be embroidered, making it flatter and improving the quality of the embroidery. Attached Figure Description

[0046] The implementation principle of a small embroidery machine according to an embodiment of this application is as follows: The operator lays the object to be embroidered flat on the rotating frame 3. The object is clamped by the mutual attraction between the second magnet 45 on the magnetic ring 41 and the first magnet 31 on the rotating frame 3. The needle 423 pierces the object and inserts into the sliding block 321. Afterwards, the operator can adjust the angle between the object to be embroidered and the machine head 12 using the drive component 5. The drive motor 53 drives the worm gear 55 to rotate, the worm gear 55 drives the worm wheel 54 to rotate, the worm wheel 54 drives the gear 52 to rotate, the gear 52 drives the gear ring 51 to rotate, and the gear ring 51 carries... The rotating frame 3 rotates relative to the embroidery frame 2, adjusting the object to be embroidered to the required angle. Then, the rotating drive ring 441 rotates, causing the sliding groove 443 on the drive ring 441 to move the drive column 442. The drive column 442 drives the transmission belt 421 to rotate, which in turn causes the transmission roller 422 to rotate. The transmission roller 422 drives the ratchet 8 to rotate. At this time, the pawl 81 cannot engage the ratchet 8. When the worker releases the drive ring 441, the pawl 81 is held engaged on the ratchet 8 by the limiting spring 82, and the transmission belt 421 cannot rotate. The needle 423 keeps the object to be embroidered in a taut state.

[0047] The moving mechanism 11 on the embroidery machine body 1 drives the embroidery frame 2 to move, and the machine head 12 performs the embroidery operation on the workpiece. After the embroidery is completed, the operator presses the unlocking ring 431. The unlocking ring 431 drives the guide slope on the unlocking block 432 to rotate the lever 83. The lever 83 drives the pawl 81 to overcome the elastic force of the limiting spring 82 and disengage from the ratchet 8. The transmission roller 422, in a free state, under the action of the spring 322 and the relaxation of the embroidery, drives the needle 423 to move in the axial direction of the magnetic ring 41. Then, the magnetic frame 4 is disengaged from the rotating frame 3, and the relaxed embroidery can be easily separated from the needle 423. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
