Description

Technical Field

[0001] The utility model relates to the field of clothing mechanism equipment, in particular to a balanced cutting placket machine. Background Art

[0002] The opening on the chest of a garment, such as the placket on the collar of a polo shirt, is called a placket. The placket is the most prominent feature of many garments, complementing the collar and pocket openings to create a vibrant and elegant look. There are countless styles of plackets available.

[0003] At present, the most common way to cut the opening of a placket is to use a placket machine instead of manual cutting. Specifically, the placket machine uses the upper cutter to press the fabric downward against the vibration plate of the ultrasonic vibration device. The vibration generated by the vibration plate drives the fabric and the cutter to instantly rub against each other to generate high temperature and heat, thereby melting the fabric, thereby forming an incision, which forms the placket.

[0004] However, this type of placket machine will inevitably be used to cut fabrics of inconsistent thickness. For example, one side of the fabric is folded and the other side is not folded. At this time, the fabric on the folded end is thicker, and the fabric on the folded end is thinner. When the cutter presses down on the thicker end of the fabric, the height of the thinner end of the fabric is lower, resulting in the cutter not being able to touch it or the downward pressure when it touches it is small, and the cutter cannot press the fabric tightly on the vibration plate. Therefore, part of the fabric on the vibration plate may not be cut, and secondary cutting is required, so the efficiency is low. Utility Model Content

[0005] In view of the deficiencies raised in the above background technology, the present invention provides a placket machine with balanced cutting.

[0006] The utility model adopts the following technical solutions:

[0007] A balanced cutting placket machine, the placket machine comprising:

[0008] A workbench, on which a connecting frame is fixed;

[0009] An ultrasonic vibration module, wherein the ultrasonic vibration module is fixed under the workbench, and the vibration plate of the ultrasonic vibrator is exposed on the upper surface of the workbench;

[0010] A cutting module, comprising a cutting cylinder and a cutting knife, wherein the cutting cylinder is fixed to the connecting frame, the cutting knife is connected to the piston rod of the cutting cylinder, and the cutting knife corresponds to the vibration plate;

[0011] The cutting cylinder is provided with guide holes passing through on both sides of the piston rod, and guide rods are embedded in the two guide holes. A recessed connecting hole is provided at the upper end of the guide rod, and a spring is embedded in the connecting hole. A sealing plate is fixed on the cutting cylinder, and the sealing plate seals the guide hole of the cutting cylinder. The upper end of the spring extends out of the connecting hole and presses against the sealing plate, and the elastic action of the spring stretching presses the guide rod downward toward the cutting knife.

[0012] In a possible implementation, a threaded hole is provided on the bottom surface of the guide rod, and the threaded hole is adapted to be screwed onto an adjusting bolt, and the screw head of the adjusting bolt presses downward toward the cutting knife.

[0013] In one possible implementation, a limit block is adapted to be embedded in the guide hole. After the spring is embedded in the connecting hole along the guide hole, the limit block is embedded in the guide hole and is sealed in the guide hole by the sealing plate, so that the upper end of the spring is pushed toward the limit block and then toward the sealing plate through the limit block.

[0014] In one possible implementation, both sides of the connecting frame are side panels, the cutting cylinder is fixed between the two side panels, the sealing plate is fixed to the upper surface of the cutting cylinder, and the side panel is fixed with a pressure block on the side facing the cutting cylinder, and the pressure block is pressed toward the sealing plate.

[0015] In one possible implementation, a tool holder is fixed under the piston rod, and a row of fixing bolts are threadedly connected to the side of the tool holder. The fixing bolts pass through the side of the cutter and are screwed to the tool holder to be fastened, so as to fix the cutter to the side of the tool holder.

[0016] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the present invention drives the cutter down by the piston rod of the cutting cylinder to press the fabric against the vibration plate, and at the same time uses the elastic force of the spring in the cutting cylinder to press down the two guide rods respectively, and provides additional downward pressure to the two ends of the cutter through the two guide rods, so that the two ends of the cutter can press the front and back of the fabric against the vibration plate evenly, avoiding one end of the cutter pressing the thicker fabric and causing the other end to be unable to press the fabric against the vibration plate, so that the fabric can be cut at one time, which is beneficial to improving the efficiency of clothing processing.

[0023] To make the objectives, technical solutions, and advantages of this application more clear, the present application will be further described in detail below with reference to the accompanying drawings. Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of components schematically shown in the accompanying drawings. It should be understood that these directional terms are relative concepts and are used for relative description and clarification. They may change accordingly depending on the orientation of the components in the accompanying drawings.

[0024] The utility model provides a balanced cutting placket machine, as shown in the attached Figure 1 and 2 As shown, the placket machine includes a workbench 1, an ultrasonic vibration module 2 and a cutting module 3. The ultrasonic vibration module 2 is fixed under the workbench 1, a connecting frame 11 is fixed on the workbench 1, and the cutting module 3 is fixed on the connecting frame 11, and the cutting module 3 corresponds to the ultrasonic vibration module 2.

[0025] Continue to refer to the attached Figure 2 The ultrasonic vibration module is an ultrasonic vibration machine in the prior art. The vibrator transducer 21 of the ultrasonic vibration module 2 is fixed to the bottom surface of the workbench 1, the vibration plate 22 of the ultrasonic vibration module 2 is exposed on the upper surface of the workbench 1, and the upper end of the amplitude rod of the vibrator transducer 21 is connected to the vibration plate 22, thereby forming a structure in which the ultrasonic vibrator transducer 21 drives the vibration plate 22 to vibrate.

[0026] As attached Figure 3 and 4 As shown, the cutting module 3 includes a cutting cylinder 31 and a cutting blade 32. The cutting cylinder 31 is fixed to the connecting frame 11. The fixing method can be that the connecting frame 11 has side panels 111 on both sides, and the cutting cylinder 31 is embedded between the two side panels 111. Screws are inserted inward from the outside of the two side panels 111 until the screws pass through the side panels 111 and screw the cutting cylinder 31 to secure the cutting cylinder 31 between the two side panels 111. Preferably, the present invention can also be equipped with a control system (not shown in the drawings). This control system can be a PLC controller for controlling the operation of the cutting cylinder 31 and the vibrator transducer 21.

[0027] As attached Figure 5 As shown, the cutting cylinder 31 can be a three-axis cylinder, with a piston rod 311 in the middle and guide rods 312 on either side of the piston rod 311. Specifically, the cylinder body of the cutting cylinder 31 is provided with vertical guide holes 3101 on both sides of the piston rod 311. The guide rods 312 are embedded in the two guide holes 3101. The lower end of the piston rod 311 is pivotally connected to the connecting plate 36. The pivot structure can be a pin connecting the upper end of the connecting plate 36 and the lower end of the piston rod 311, so that the connecting plate 36 and the piston rod 311 can rotate relative to each other only about the pin.

[0028] Furthermore, a connecting rod (not shown in the drawings) can be fixed to the bottom of the connecting plate 36, and a knife holder 35 for mounting the cutter 32 is fixed under the connecting rod. This forms a structure in which the cutter 32 is fixed to the bottom of the piston rod 311 of the cutting cylinder 31, and the cutter 32 corresponds to the top of the vibration plate 22. When cutting the placket, the fabric is spread flat on the workbench 1, and the part to be cut is aligned with the cutter 32. Then, the cutting cylinder 31 is controlled to drive the cutter 32 down until the fabric is pressed against the vibration plate 22. The high-frequency vibration generated by the vibration plate 22 is used to melt the fabric, completing the cutting process.

[0029] As attached Figure 4 As shown, a row of fixing bolts 351 are threadedly connected to the side of the tool holder 35. The fixing bolts 351 pass through the side of the cutter 32 and are screwed to the tool holder 35 for fastening to fix the cutter 32 to the side of the tool holder 35. This connection structure through the fixing bolts 351 can facilitate the replacement of different cutters 32 according to cutting requirements.

[0030] As attached Figure 5As shown, a recessed connection hole 3102 is provided at the upper end of the guide rod 312, into which a spring 33 is embedded. A sealing plate 12 is fixed to the cutting cylinder 31, which seals the guide hole 3101 of the cutting cylinder 31, allowing the upper end of the spring 33 to extend out of the connection hole 3102 and press against the sealing plate 12. As a result, the upper end of the spring 33 is confined within the guide hole 3101, and the elastic effect of the stretched spring 33 presses the guide rod 312 downward toward the cutter 32. Furthermore, a limit block 34 is adapted to be embedded in the guide hole 3101. After the spring 33 is embedded in the connecting hole 3102 along the guide hole 3101, the limit block 34 is then embedded in the guide hole 3101. Thereafter, the sealing plate 12 is fixedly sealed on the upper surface of the cutting cylinder 31, so that the limit block 34 and the spring 33 are both sealed in the guide hole 3101 by the sealing plate 12, thereby forming a structure in which the upper end of the spring 33 is pushed upward toward the limit block 34. This structure is equivalent to increasing the thickness of the sealing portion at the upper end of the guide hole 3101 and increasing the force area of ​​the spring 33 pushing upward toward the sealing plate 12, thereby avoiding deformation of the sealing plate 12. In addition, the side plate 111 of the connecting frame 11 is fixed with a pressure block 13 on the side facing the cutting cylinder 31, and the pressure block 13 presses against the sealing plate 12, thereby improving the firmness with which the sealing plate 12 fixes and seals the top of the cutting cylinder 31.

[0031] When the piston rod 311 of the cutting cylinder 31 drives the cutter 32 down to press the fabric against the vibration plate 22, the guide rod 312 continues to be pressed down under the elastic force of the spring 33 to apply pressure to the upper ends of the cutter 32, thereby increasing the force pressing the fabric downward against the vibration plate 22. Moreover, if the thickness of the fabric at the front and back ends is inconsistent, the additional downward force generated by the elastic force of the spring 33 can press down the ends of the cutter 32, so that both ends of the fabric with inconsistent thickness are pressed tightly, thereby achieving balanced pressure of the cutter 32 on the front and back ends of the fabric on the vibration plate 22.

[0032] In addition, as attached Figure 6 As shown, the bottom surface of the guide rod 312 can also be connected to the pressure rod 37. The bottom surface of the pressure rod 37 is provided with a threaded hole, which is adapted to be screwed into an adjustment bolt 371. The head of the adjustment bolt 371 forms the portion of the bottom of the guide rod 312 that presses downward toward the cutter 32. When the fabric to be cut is thin, the adjustment bolt 371 can be unscrewed downward to increase the overall length of the guide rod 312, allowing the guide rod 312 to descend further, driving the cutter 32 to press the fabric tightly. Thus, by rotating the adjustment bolt 371, the distance between the bottom portion of the guide rod 312 and the blade holder 35 can be adjusted after the spring 33 presses the guide rod 312 downward. This distance can be adjusted to accommodate fabrics of varying thicknesses.

[0033] Preferably, strip holes 3601 can be provided on both sides of the connecting plate 36, and the pressure rods 37 under the two guide rods 312 respectively pass through the strip holes 3601 on both sides of the connecting plate 36, and the width of the two guide rods 312 is clearance-matched with the width of the strip holes 3601 to limit the connecting plate 36 from rotating horizontally with the piston rod 311 as the axis, and the connecting plate 36 can swing relative to the piston rod 311, so that the pressure rod can press down one end of the cutter 32.

[0034] In summary, the present invention uses the piston rod 311 of the cutting cylinder 31 to drive the cutter 32 downward to press the fabric against the vibration plate 22. The vibration generated by the vibration plate 22 causes the fabric and the cutter 32 to instantly rub against each other, generating high temperature and heat, thereby melting the fabric, thereby achieving the process of cutting the fabric into a placket. If the thickness of the fabric placed on the vibration plate 22 is inconsistent at the front and back, the elastic force of the spring 33 within the cutting cylinder 31 can be used to press the ends of the cutter 32 downward against the fabric, preventing one end of the cutter 32 from pressing the thicker fabric and causing the other end to be unable to keep the fabric close to the vibration plate 22. That is, the springs 33 at both ends of the cutting cylinder 31 respectively press the two guide rods 312 downward, driving the two guide rods 312 to press the two ends of the cutter 32 downward, so that the two ends of the cutter 32 can evenly press the fabric against the vibration plate 22. Therefore, the fabric can be cut at one time, which is beneficial to improving the efficiency of garment processing.

[0035] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
