Description

Technical Field

[0001] This utility model relates to the field of children's smock production equipment, and more particularly to the die-cutting module of disposable children's smock production equipment. Background Technology

[0002] On the same day, the applicant applied for "Disposable Children's Smock Production Equipment", in which the cutting device focuses on one side of the roll material to form the neckline, headband and waistband. The currently used die-cutting roller (which matches the width of the whole machine) leaves a lot of blank space on the other side, resulting in waste.

[0003] In addition, existing die-cutting devices have the following problems: the die-cutting rollers are inconvenient to adjust up and down, and the screws of traditional screw lifting structures are prone to bending due to long-term stress, the threads will gradually wear, the gap will increase, and the service life will be short. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a die-cutting module for a disposable children's smock production equipment that is easy to adjust.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a die-cutting module for a disposable children's smock production equipment, comprising a mounting bracket and a die-cutting device. The mounting bracket is equipped with a material feeding channel for the roll material to pass through. The die-cutting module is mounted on the mounting bracket and performs die-cutting on the roll material in the material feeding channel. The die-cutting device includes a die-cutting roller, a pressure roller, and a first power source for driving the die-cutting roller to rotate. The first power source is connected to the die-cutting roller via a telescopic universal coupling. The die-cutting roller is mounted on an upper mounting base, and the pressure roller is mounted on a lower mounting base. Both ends of the die-cutting roller are connected to the upper mounting base via lifting bearing seats. The bottom of the lifting bearing seat has a first inclined surface. The upper mounting base is provided with a horizontally movable inclined block. The inclined block has a second inclined surface that fits against the first inclined surface. The inclined block has a second power source that drives it to move horizontally. The second power source drives the inclined block to move horizontally to adjust the vertical position of the lifting bearing seat.

[0006] The die-cutting device of this invention is integrated on a mounting bracket and can be directly assembled onto the garment production equipment for easy replacement. The die-cutting roller of the device die-cuts the roll material. The inclined block contacts the lifting bearing seat surface, resulting in a larger contact area, stronger relative rigidity, and a longer service life. The power source drives the horizontal movement of the inclined block to adjust the vertical position of the die-cutting roller, improving adjustment accuracy. Furthermore, during the lifting and lowering of the die-cutting roller, a telescopic universal coupling automatically compensates for inter-shaft displacement, ensuring stable power transmission and stable operation of the die-cutting device.

[0007] Preferably, the upper end of the upper mounting base is provided with a screw, and the bottom of the screw is fixed with an abutment block. A spring is provided between the abutment block and the lifting bearing seat. When the screw rotates downward, the abutment block compresses the spring, so that the spring force drives the lifting bearing seat to be tightly connected with the inclined block. In addition, the spring can also reduce vibration and eliminate the impact of different coil thicknesses during equipment operation.

[0008] Preferably, the axial length of the die-cutting roller matches the axial length of the desired die-cutting pattern on the roll material, and the axial length of the pressure roller is compatible with the axial direction of the die-cutting roller. This reduces the blank area of ​​the die-cutting roller and lowers production costs.

[0009] Furthermore, the mounting bracket is installed on the frame in a laterally adjustable manner. Because the length of the die-cutting roller is adapted to the length of the die-cutting pattern, space is left on one side of the frame for the mounting bracket to move. The lateral adjustment of the mounting bracket can accommodate rolls of material with different widths, improving the versatility of the equipment.

[0010] With the mounting bracket being horizontally adjustable, support plates are provided on both sides of the frame, and the mounting bracket is set on the frame by adjusting left and right sides via a horizontal guide groove.

[0011] Preferably, the upper mounting base has scale markings for measuring the movement distance of the wedge block, making the displacement of the wedge block visible. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] The die-cutting module of a disposable children's smock production equipment includes a mounting bracket 2 and a die-cutting device 3. The mounting bracket 2 is equipped with a material feeding channel 23 for the roll material to pass through. The mounting bracket 2 is mounted on a frame 1 and includes a front plate, a rear plate, and a connecting plate. The front plate and the rear plate are connected by the connecting plate, and each of the front and rear plates has a gap. The gaps are connected to form the material feeding channel 23 for the roll material to pass through. The die-cutting module is mounted on the mounting bracket 2 and performs die-cutting on the roll material in the material feeding channel 23. The die-cutting device 3 includes a die-cutting roller 31, a pressure roller 32, and a first power source 4 for driving the die-cutting roller 31 to rotate. The cutting edge of the die-cutting blade on the die-cutting roller 31 has an intermittent serrated structure, although the cutting edge can also be a straight structure. The first power source 4 is connected to the die-cutting roller 31 through a telescopic universal coupling 5. The telescopic universal coupling 5 is existing technology and will not be described in detail here. The die-cutting roller 31 is mounted on the upper mounting base 21, and the pressure roller 32 is mounted on the lower mounting base 22. The die-cutting roller 31 is connected to the mounting bracket 2 via the upper mounting base 21, and the pressure roller 32 is connected to the mounting bracket 2 via the lower mounting base 22. There is a gap between the upper mounting base 21 and the lower mounting base 22, which is part of the material passage 23. Both ends of the die-cutting roller 31 are connected to the upper mounting base via lifting bearing seats 33. The bottom of the lifting bearing seat 33 has a first inclined surface. The upper mounting base is provided with a horizontally movable inclined block 6, which slides on the upper mounting base. The inclined block 6 has a second inclined surface that fits against the first inclined surface. The inclined block 6 is in surface contact with the lifting bearing seat 33, increasing the contact area. The inclined block 6 has stronger rigidity relative to the screw 8 and a longer service life. The inclined block 6 has a second power source that drives it to move horizontally. The second power source drives the inclined block 6 to move horizontally to adjust the vertical position of the lifting bearing seat 33. The power source of the inclined block 6 can be an automatic cylinder or a motor, or a manual adjusting screw 7. The adjusting screw 7 is located on the side of the upper mounting seat 21. The bottom end of the adjusting screw 7 is fixedly connected to the inclined block 6. By rotating the adjusting screw 7 (thread not shown in the figure), the slider is driven to move horizontally, thereby realizing the precise adjustment of the vertical position of the die-cutting roller 31. The adjusting screw 7 can also lock and position the inclined block 6.

[0019] Working Principle: During machine adjustment, the second power source drives the inclined block 6 to move horizontally, as shown in the figure. When the inclined block 6 slides to the right, the lifting bearing seat 33 drives the die-cutting roller 31 to move upward; when the inclined block 6 slides to the left, the lifting bearing seat 33 drives the die-cutting roller 31 to move downward, adjusting the vertical position of the die-cutting roller 31. During the adjustment of the die-cutting roller 31, the first power source 4 compensates for the inter-shaft displacement of the die-cutting roller 31 through the telescopic universal coupling 5, ensuring stable power transmission during die-cutting. The die-cutting roller 31 is mounted on the mounting bracket 2 via the upper mounting seat, and the lower die-cutting roller 31 is mounted on the mounting bracket 2 via the lower mounting seat 22. The die-cutting device 3 can be installed on the frame 1 after being mounted on the mounting bracket 2, reducing downtime when changing die-cutting patterns.

[0020] To ensure a tight fit between the lifting bearing seat 33 and the inclined block 6, the upper end of the upper mounting base 21 is provided with a screw 8 (thread not shown in the figure). A stop block 9 is fixedly provided at the bottom of the screw 8. A spring 10 is provided between the stop block 9 and the lifting bearing seat 33. The upper end of the spring 10 contacts the stop block 9, and the lower end of the spring 10 contacts the lifting bearing seat 33. The spring 10 can buffer the die-cutting roller 31 on the bearing seat. During the downward rotation of the screw 8, the stop block 9 is driven to compress the spring 10. The elastic force of the spring 10 makes the lifting bearing and the inclined block 6 fit tightly. With the spring 10, the inclined block 6 can also prevent the lifting bearing seat 33 from floating too much. The cooperation between the screw 8, the spring 10, the lifting bearing seat 33 and the inclined block 6 ensures the stable operation of the die-cutting device 3 and improves the yield.

[0021] Because the neckline of children's smocks is only cut on one side of the roll material, conventional die-cutting rollers have blank areas, increasing replacement costs. To reduce replacement costs, the axial length of the die-cutting roller 31 matches the axial length of the required die-cut pattern on the roll material; that is, the axial length of the die-cutting roller 31 is not less than the length of the die-cut pattern on the roll material, but without generating excess blank space except for assembly requirements. The axial length of the pressure roller 32 is compatible with the axial length of the die-cutting roller 31 (see...). Figure 4 The pressure roller 32 and the die-cutting roller 31 work together to die-cut the roll material, therefore their axial lengths should be consistent. To avoid a large blank area on the die-cutting roller 31, the axial length of the die-cutting roller 31 is shortened, reducing manufacturing costs. At the same time, a blank area is left on one side of the frame 1 to avoid an overly compact structure. Based on the blank area on one side of the frame 1, the mounting bracket 2 is installed on the frame 1 in a laterally adjustable manner, allowing the die-cutting device 3 to adapt to roll materials of different widths. There are several ways to laterally adjust the mounting bracket 2. For example, the frame 1 has support plates 11 on both sides, and the support plates 11 have transverse guide grooves. The mounting bracket 2 is adjusted left and right on the frame 1 through the transverse guide grooves. Alternatively, the mounting bracket 2 can also move left and right relative to the frame 1 through a sliding groove.

[0022] To visualize the movement of the inclined block 6, the upper mounting base has a scale marking (not shown in the figure) for measuring the movement distance of the inclined block 6, and the lifting height of the die-cutting roller 31 can be calculated from the movement of the inclined block 6.
