Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a highly stable longitudinal and transverse drive device for embroidery machines. Background Technology

[0002] The longitudinal and transverse drive mechanism of an embroidery machine is an important component of the machine. It is responsible for driving the embroidery frame to move precisely in the longitudinal (X-axis) and transverse (Y-axis) directions to achieve accurate embroidery of patterns.

[0003] For reference, see existing literature such as Computerized Embroidery Machine Needle Bar Frame Drive Device (CN202559084U) and Digital Control Embroidery Machine Longitudinal and Transverse Drive Device (CN202969002U).

[0004] In existing technology, the longitudinal and transverse drive devices of embroidery machines usually adopt a combination structure of screw and screw seat. The two slide rails are arranged in a cross shape to drive the needle bar frame to move longitudinally and laterally. When positioning the needle bar frame, positioning is usually achieved by controlling the motor and the self-locking property of the screw and screw seat. However, positioning by screw self-locking alone is easily affected by external factors and may cause slippage. In addition, the two slide rails of longitudinal and transverse are generally integrated and installed in a designated position on the embroidery machine, which makes it inconvenient to disassemble and maintain them later. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly stable longitudinal and transverse drive device for embroidery machines. This invention, after the needle bar holder is positioned by the screw seat, can activate the electromagnet, allowing the magnetic blocks on the screw seat surface to attract the electromagnet and perform secondary positioning of the screw seat, thus improving operational stability. Furthermore, this drive mechanism adopts a modular design, connecting the transverse and longitudinal slide rails via clamping slide rails, allowing for the replacement of individual units during subsequent maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A highly stable embroidery machine longitudinal and transverse drive device includes: a transverse slide rail, a clamping slide rail, and a longitudinal slide rail. Both the transverse and longitudinal slide rails have linearly movable screw seats inside. Limit seats are fixed at the top of the transverse slide rail and the bottom of the longitudinal slide rail. Electromagnets are embedded and fixed inside the limit seats. Magnetic blocks are provided on the side of each screw seat away from the center. The magnetic blocks are slidably mounted inside the limit seats and contact the electromagnets. The clamping slide rail has a built-in clamping assembly, which includes two opposing sliding blocks. Limit plates are fixed at both ends of each sliding block. Each screw seat has a mating seat on the side near the center. Limit slots are opened on both sides of the mating seat, and the limit plates are inserted into the limit slots.

[0008] The present invention is further configured such that bearings are embedded and fixed at both ends of the transverse slide rail and the longitudinal slide rail, and lead screws are movably arranged on the inner side of the transverse slide rail and the longitudinal slide rail. Both ends of the lead screws are provided with smooth extension ends, which are fixed in the inner ring of the bearings.

[0009] The present invention is further configured such that the lead screw seat is threaded to the outside of the lead screw and is slidably mounted on the inside of the transverse slide rail and the longitudinal slide rail.

[0010] The present invention is further configured such that a servo motor is fixedly installed at one end of both the transverse slide rail and the longitudinal slide rail, and the output end of the servo motor is fixed to one extension end of the lead screw.

[0011] The present invention is further configured as follows: the clamping assembly includes a double-headed cylinder, which is fixedly installed on the inner side of the clamping slide rail, and two sliders are respectively connected to the two telescopic ends of the double-headed cylinder.

[0012] The present invention is further configured such that both the upper and lower ends of the clamping slide rail are provided with slide grooves II, and both sliders move in slide grooves II. A slide groove I is provided at the end of the docking seat near the center, and the limiting insert plate moves in slide groove I.

[0013] The present invention is further configured such that a mounting plate is provided on the top of the upper limiting seat, and sliding grooves are provided on both sides of the longitudinal slide rail. Brackets are fixed at both ends of the lower lead screw seat. Both brackets move in the sliding grooves and the other ends of both brackets are fixed to the mounting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During the positioning process, the servo motor drives the lead screw to rotate in the longitudinal and transverse drive device of this embroidery machine. Under the control of the servo motor, the lead screw seat moves to the designated position. At this time, the electromagnet inside the limit seat is energized, and the magnetic block on the surface of the lead screw seat will be attracted to the designated position of the electromagnet. This can be used in conjunction with the thread self-locking property of the lead screw seat and the lead screw to perform secondary positioning, improve positioning stability and reduce the influence of the external environment.

[0016] 2. The embroidery machine's longitudinal and transverse drive device adopts a modular design. The transverse and longitudinal slide rails are connected by clamping slide rails. The operation of the clamping components inside the clamping slide rails allows the limiting insert plate to fit into the limiting insert of the docking seat. Correspondingly, the connection between the transverse and longitudinal slide rails can be quickly released through the clamping components, making subsequent disassembly and maintenance more convenient.

[0026] Reference Figure 1-4 A highly stable embroidery machine longitudinal and transverse drive device includes: a transverse slide rail 1, a clamping slide rail 2, and a longitudinal slide rail 3. The transverse slide rail 1 and the longitudinal slide rail 3 are arranged in a cross shape and are used to drive the needle bar frame to move laterally and longitudinally, respectively. The clamping slide rail 2 has a built-in clamping component to connect the transverse slide rail 1 and the longitudinal slide rail 3.

[0027] Specifically, the internal structures of the transverse slide rail 1 and the longitudinal slide rail 3 are as follows: Figure 2 As shown, bearings 10 are embedded and fixed at both ends of the transverse slide rail 1 and the longitudinal slide rail 3. A lead screw 8 is provided on the inner side of both the transverse slide rail 1 and the longitudinal slide rail 3. Both ends of the lead screw 8 are smooth extension ends, and both extension ends are fixed in the inner ring of the bearing 10.

[0028] With this design, bearing 10 can reduce the rotational friction of lead screw 8.

[0029] Furthermore, the lead screw 8 is externally threaded to a lead screw seat 9, which is slidably mounted on the inner side of the transverse slide rail 1 and the longitudinal slide rail 3. A servo motor 7 is fixedly mounted at one end of both the transverse slide rail 1 and the longitudinal slide rail 3, and the output end of the servo motor 7 is fixed to one extension end of the lead screw 8.

[0030] In this embodiment, the servo motor 7 drives the lead screw 8 to rotate, so that the lead screw seat 9 outside the lead screw 8 moves linearly inside the transverse slide rail 1 and the longitudinal slide rail 3.

[0031] Specifically, in combination Figure 2 and Figure 4 As shown, a magnetic block 19 is fixed at the end of the lead screw seat 9 away from the center, and a limit seat 4 is installed above the transverse slide rail 1 and at the bottom of the longitudinal slide rail 3.

[0032] Furthermore, an electromagnet 5 is embedded and installed inside the limiting seat 4, and the magnetic blocks 19 are all located inside the limiting seat 4 and slide in contact with the electromagnet 5.

[0033] Therefore, after the lead screw seat 9 is positioned, the magnetic block 19 also moves to the corresponding position inside the limit seat 4. At this time, the electromagnet 5 is energized to generate magnetism, so that the magnetic block 19 is attracted to the corresponding position on the surface of the electromagnet 5, thus completing the secondary positioning.

[0034] Specifically, in combination Figure 2 and Figure 4 As shown, a docking seat 11 is fixed at one end of the lead screw seat 9 near the center. The docking seat 11 has a sliding groove 12 at one end near the center and limit insertion ports 13 on both sides.

[0035] Clamping components such as Figure 3 As shown, a double-headed cylinder 14 is fixedly installed inside the clamping slide rail 2, and sliders 15 are fixed to both telescopic ends of the double-headed cylinder 14.

[0036] Meanwhile, a second groove 17 is provided at both the upper and lower ends of the clamping slide rail 2. The sliders 15 pass through the second groove 17 and move within the second groove 17. A limiting plate 16 is integrally connected to both ends of the sliders 15.

[0037] In this embodiment, the clamping slide rail 2 is as follows: Figure 1 As shown, the two docking seats 11 are placed between them. When the double-headed cylinder 14 is turned on, it drives the two sliders 15 to move to both sides. The two limiting plates 16 move in the slide groove 12, so that the limiting plates 16 can fit into the limiting slots 13 on both sides of the docking seat 11, thereby connecting the two docking seats 11. Correspondingly, the transverse slide rail 1 and the longitudinal slide rail 3 are docked. The modular design facilitates subsequent disassembly and maintenance.

[0038] Specifically, a mounting plate 6 is provided on the top of the upper limiting seat 4, and the device is fixed in the designated position of the embroidery machine by the mounting plate 6.

[0039] For details, please refer to Figure 4 As shown, slide grooves 18 are provided on both sides of the longitudinal slide rail 3. Both ends of the lead screw seat 9 inside the longitudinal slide rail 3 are connected to L-shaped brackets 20. The brackets 20 pass through the slide grooves 18 and move within the slide grooves 18.

[0040] Meanwhile, the other end of each of the two brackets 20 is connected to the mounting plate 21, and the needle bar bracket is fixed to the bottom of the mounting plate 21.

[0041] Working principle: During the positioning process, the servo motor 7 drives the lead screw 8 to rotate. Under the control of the servo motor 7, the lead screw seat 9 moves to the designated position. At this time, the electromagnet 5 inside the limit seat 4 is energized, and the magnetic block 19 on the surface of the lead screw seat 9 will be attracted to the designated position of the electromagnet 5. This can cooperate with the thread self-locking property of the lead screw seat 9 and the lead screw 8 to perform secondary positioning, improve positioning stability and reduce the influence of the external environment. In addition, this device adopts a modular design. The horizontal slide rail 1 and the vertical slide rail 3 are connected by the clamping slide rail 2. The operation of the clamping component inside the clamping slide rail 2 allows the limit plate 16 to fit into the limit socket 13 of the docking seat 11. Correspondingly, the connection between the horizontal slide rail 1 and the vertical slide rail 3 can be quickly released by the clamping component, making subsequent disassembly and maintenance more convenient.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
