Description

Technical Field

[0001] This utility model relates to the field of embroidery technology, specifically to an embroidery template clamping device with laser positioning. Background Technology

[0002] Embroidery machines, also known as computerized embroidery machines, are the most advanced embroidery machinery of our time. They enable traditional hand embroidery to be completed at high speed and efficiency, and can also achieve the requirements of "multi-layer, multi-functional, uniform and perfect" that hand embroidery cannot reach. It is an electromechanical product that embodies a variety of high-tech features. As computerized embroidery replaces hand embroidery, computerized embroidery machines will become the main type of machine in the embroidery industry.

[0003] A search revealed that existing embroidery machines, such as the one disclosed in Chinese Patent Publication No. CN110923975B, solve the problem that existing embroidery machines use separate machines for planar embroidery structures and cylindrical embroidery mechanisms, resulting in limited functionality. The embroidery machine includes a support frame, a machine head at the top of the support frame, and a worktable between the machine head and the support frame. The worktable further includes a longitudinal feeding mechanism fixedly connected to the support frame, a transverse feeding mechanism at the top of the longitudinal feeding mechanism, a drive mechanism inside the transverse feeding mechanism, a switching mechanism located inside the transverse feeding mechanism on one side of the drive mechanism, and two symmetrically distributed planar clamping mechanisms connected to the switching mechanism on the front of the transverse feeding mechanism.

[0004] When this embroidery machine is working, the embroidery template is clamped and fixed by a planar clamping mechanism. During clamping, both ends of the embroidery template are inserted into the clamping plate, thereby limiting and fixing the embroidery template. However, in actual operation, if both ends of the embroidery template are not fully inserted into the clamping plate, one end may fall off during the embroidery process due to the movement of the embroidery template, thus affecting the normal embroidery work. To address this issue, we propose an embroidery template clamping device with laser positioning to solve the above problem. Utility Model Content

[0005] The purpose of this invention is to provide an embroidery template clamping device with laser positioning to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embroidery template clamping device with laser positioning, comprising a mounting crossbar, with connecting seats fixedly connected to both ends of the bottom of the mounting crossbar, and adjusting grooves respectively opened on both sides of one end of the mounting crossbar, with threaded rods rotatably installed in the adjusting grooves, and the output shaft ends of a dual-output shaft motor fixedly connected to the opposite ends of the threaded rods, the dual-output shaft motor being fixedly installed in the middle of the mounting crossbar;

[0007] One end of each adjusting rod is slidably connected within the adjusting groove. Each adjusting rod is connected to a threaded rod via a threaded structure. Each adjusting rod has a recessed mounting groove on its opposite end face. A pressure plate is movably mounted near the opening of each mounting groove. A drive shaft is fixedly sleeved on one side of each pressure plate. The drive shaft is rotatably mounted within the mounting groove, and one end of each drive shaft is fixedly connected to the output shaft of a drive motor. The drive motor is fixedly mounted on the side of the adjusting rod away from the mounting crossbar. A laser sensor is fixedly mounted on the other side of one end face of the adjusting rod.

[0008] Preferably, the laser sensor emitter head of the laser sensor is flush with the inner wall of the mounting groove away from the opening.

[0009] Preferably, the width of the pressure plate is greater than or equal to the opening width of the mounting groove.

[0010] Preferably, a rubber sheet is fixedly connected to the outer surface of the end of the pressure plate away from the drive shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the installed laser sensor, the laser sensor emits a laser beam toward the mounting groove. When both ends of the embroidery template are inserted into the mounting groove, if the ends of the embroidery template are tightly attached to the inner wall of the mounting groove, the embroidery template blocks the laser beam, and the embroidery template is installed in place. If the ends of the embroidery template are not tightly attached to the inner wall of the mounting groove, the laser beam passes through the gap between the embroidery template and the inner wall of the mounting groove, and the embroidery template is not installed in place. Then, the adjusting rod is moved again to position and fix the embroidery template. Finally, the pressure plate presses and limits the two ends of the embroidery template, further ensuring the clamping and fixing of the embroidery template. Attached Figure Description

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Reference Figure 1 , 2 This is the first embodiment of the present utility model. This embodiment provides an embroidery template clamping device with laser positioning, including a mounting crossbar 1. The bottom two ends of the mounting crossbar 1 are respectively fixedly connected to the connecting seats 10. Adjustment grooves 2 are respectively opened on both sides of one end of the mounting crossbar 1. Threaded rods 4 are rotatably installed in the adjustment grooves 2. The opposite ends of the threaded rods 4 are respectively fixedly connected to the output shaft ends of the dual output shaft motor 3. The dual output shaft motor 3 is fixedly installed in the middle of the mounting crossbar 1.

[0018] One end of the adjusting rod 5 is slidably connected in the adjusting groove 2. The adjusting rod 5 is connected to the threaded rod 4 through a threaded structure. The opposite end face of the adjusting rod 5 is respectively provided with an installation groove 6. The pressure plate 7 is movably provided in the installation groove 6 near the opening. The transmission shaft 11 is fixedly sleeved on one side of the pressure plate 7. The transmission shaft 11 is rotatably installed in the installation groove 6 and one end of the transmission shaft 11 is fixedly connected to the output shaft of the drive motor 8. The drive motor 8 is fixedly installed on the side of the adjusting rod 5 away from the installation crossbar 1. The laser sensor 9 is fixedly installed on the other side of the end face of the adjusting rod 5.

[0019] The middle of the end of the mounting bar 1 furthest from the adjusting slide 2 is connected to the X drive of the embroidery machine. The bottom of the connecting seat 10 is connected to the Y drive of the embroidery machine. The dual output shaft motor 3, laser sensor 9, and drive motor 8 are connected to the power supply and the computer control system of the embroidery machine via wiring. When the embroidery template is installed, the dual output shaft motor 3 is powered on and drives the threaded rods 4 to rotate. The threaded rods 4 drive the adjusting rods 5 to move away from each other through the threaded structure. After the adjusting rods 5 are moved to a suitable distance, the embroidery template is placed between the two adjusting rods 5. Then the dual output shaft motor 3 reverses its operation, and through the cooperation of various components, drives the adjusting rods 5 to move away from each other. As the adjusting rod 5 approaches, both ends of the embroidery template are inserted into the mounting groove 6. After the ends of the embroidery template are pressed tightly against the inner wall of the mounting groove 6, the embroidery template completely blocks the laser beam emitted by the laser sensor emitter 91 of the laser sensor 9. The embroidery template is then installed in place. Then, the drive motor 8 is powered on and drives the fixed transmission shaft 11 to rotate. The transmission shaft 11 drives the fixed pressure plate 7 to rotate. The pressure plate 7 rotates towards the embroidery template. The pressure plate 7 cooperates with the bottom wall of the mounting groove 6 to press the ends of the embroidery template, ensuring the stability of the embroidery template and preventing the embroidery template from shifting.

[0020] Example 2

[0021] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the laser sensor emitting head 91 of the laser sensor 9 is flush with the inner wall of the mounting groove 6 away from the opening. That is, the laser beam emitted by the laser sensor emitting head 91 of the laser sensor 9 is flush with the inner wall of the mounting groove 6. Then, after the two ends of the embroidery template are inserted into the mounting groove 6, if the ends of the embroidery template are tightly attached to the inner wall of the mounting groove 6, the embroidery template blocks the laser beam, and the embroidery template is installed in place. If the ends of the embroidery template are not tightly attached to the inner wall of the mounting groove 6, the laser beam passes through the gap between the embroidery template and the inner wall of the mounting groove 6, and the embroidery template is not installed in place, thus realizing the operation of installing and positioning the embroidery template.

[0022] Specifically, the width of the pressure plate 7 is greater than or equal to the opening width of the mounting groove 6, so that when the pressure plate 7 rotates, the pressure plate 7 can completely abut against the inner wall of the mounting groove 6, preventing the pressure plate 7 from rotating completely, so that the pressure plate 7 cooperates with the bottom of the mounting groove 6 to perform a pressing operation on the end of the embroidery template.

[0023] Specifically, rubber sheets are fixedly connected to the outer surface of the end of the pressure plate 7 away from the drive shaft 11. The rubber sheets increase the friction of the pressure plate 7 on the pressing position of the embroidery template, and at the same time prevent the pressure plate 7 from damaging the end of the embroidery template.

[0024] Example 3

[0025] Reference Figure 1-2This is the third embodiment of the present invention. Based on the previous two embodiments, in use, the middle of the end of the mounting bar 1 furthest from the adjusting slide 2 is connected to the X-drive of the embroidery machine. The bottom end of the connecting seat 10 is connected to the Y-drive of the embroidery machine. The dual-output shaft motor 3, laser sensor 9, and drive motor 8 are connected to the power supply and the computer control system of the embroidery machine via wiring. When the embroidery template is installed, the dual-output shaft motor 3 is powered on, driving the threaded rods 4 to rotate. The threaded rods 4, through their threaded structure, drive the adjusting rods 5 to move away from each other. After the adjusting rods 5 have moved to a suitable distance, the embroidery template is placed between the two adjusting rods 5. Then, the dual-output shaft motor 3 reverses its operation. With the cooperation of various components, the adjusting rods 5 are brought closer together. After the adjusting rods 5 are close together, both ends of the embroidery template are inserted into the mounting grooves 6. After the ends of the embroidery template are pressed tightly against the inner wall of the mounting groove 6, the embroidery template completely blocks the laser beam emitted by the laser sensor emitter 91 of the laser sensor 9. The embroidery template is then installed in place. Then the drive motor 8 is powered on and drives the fixed transmission shaft 11 to rotate. The transmission shaft 11 drives the fixed pressure plate 7 to rotate. The pressure plate 7 rotates towards the embroidery template. The pressure plate 7 cooperates with the bottom wall of the mounting groove 6 to press the ends of the embroidery template, ensuring the stability of the embroidery template and preventing the embroidery template from shifting.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
