Description

Technical Field

[0001] This utility model relates to the field of bed processing equipment technology, and in particular to a bed frame paper mold cutting device. Background Technology

[0002] In the manufacturing process of bed frames, they are typically composed of a wooden frame, a sponge filling layer, and an outermost layer of bed frame fabric. Before the fabric is applied, a special paper template of the bed frame is often made based on its three-dimensional structure. The precision of the paper template cutting directly affects the efficiency of subsequent fabric cutting and the fit of the final product.

[0003] Currently, laser cutting technology is widely used in the industry to complete the cutting process. For example, Chinese Patent Publication No. CN119368946A discloses an intelligent laser garment cutting bed and cutting method. This equipment integrates functions such as fabric unwinding, ironing, conveying and positioning, and laser cutting. It can improve the edge quality and accuracy of the cutting trajectory through secondary ironing.

[0004] However, such laser cutting equipment also has significant shortcomings in practical applications. Before cutting, the fabric needs to be drawn out from the feed roller and manually pulled to lay flat and cover the entire processing table. This process usually requires operators to pull the fabric through the narrow space under the laser head, which is not only difficult to operate but also often requires two people to complete, severely restricting the production rhythm, resulting in low overall pulling efficiency and high labor costs.

[0018] Please refer to Figures 1-5 This embodiment discloses a paper template cutting device for bed frames, including a support 10, a feeding mechanism 20, an x-axis translation mechanism 30, a y-axis translation mechanism 40, a laser head 50, and a clamping mechanism 60; the support 10 is provided with an operating table 11.

[0019] The feeding mechanism 20 is located on one side of the operating table 11 along the x-direction. The feeding mechanism 20 includes two mounting plates 21 fixed to the bracket 10 and a feeding roller 22 rotatably disposed between the two mounting plates 21. The x-direction translation mechanism 30 includes two x-direction drive devices 31 located on both sides of the operating table 11 along the y-direction, and x-direction sliding seats 32 pulsatingly connected to each x-direction drive device 31. The y-direction translation mechanism 40 includes a first y-direction drive device 41 connected between the two x-direction sliding seats 32, and a y-direction sliding seat 42 pulsatingly connected to the first y-direction drive device 41. The laser head 50 is fixed to the y-direction sliding seat 42. The upper part of the slide is facing the operating table 11; each x-axis slide seat 32 is provided with a set of clamping mechanisms 60, and the two sets of clamping mechanisms 60 are arranged opposite to each other; the clamping mechanism 60 includes a second y-axis driving device 61 fixed on the x-axis slide seat 32, a y-axis slider connected to the second y-axis driving device 61, a vertical plate 62 fixed on the y-axis slider, an upper clamping plate 63 fixed at the lower end of the vertical plate 62, a z-axis driving device 64 installed on the side of the vertical plate 62, and a lower clamping plate 65 connected to the output end of the z-axis driving device 64; a clamping gap 601 for clamping the paper model of the bed frame is formed between the upper clamping plate 63 and the lower clamping plate 65.

[0020] The specific working process of the bed frame paper template cutting equipment is as follows: The rolled bed frame paper template is installed on the feeding roller 22. At the beginning of the operation, the free end of the fabric is initially guided to the top of the operating table 11 by the operator. Subsequently, the two sets of clamping mechanisms 60 operate synchronously. The second y-direction drive device 61 drives the vertical plate 62 and the upper clamping plate 63 and lower clamping plate 65 on it to move along the y-direction and adjust them to the predetermined clamping position, so that the two corners of the fabric are respectively placed at the clamping gap 601 formed by the upper clamping plate 63 and lower clamping plate 65 of the two sets of clamping mechanisms 60. Then, the z-direction drive device 64 operates to push the lower clamping plate 65 up, which works with the fixed upper clamping plate 63 to firmly hold the fabric. After clamping, the X-axis translation mechanism 30 is activated, and its X-axis drive device 31 drives the X-axis sliding seats 32 on both sides to move synchronously to the other side of the operating table 11, thereby automatically and smoothly pulling the fabric out through the clamping mechanism 60. When the fabric is pulled to the target position, the Z-axis drive device 64 controls the lower clamping plate 65 to descend and release the fabric, and the second Y-axis drive device 61 then drives the entire clamping mechanism 60 to reset and move away, so that the pulled end of the fabric is laid flat on the operating table 11. Finally, the X-axis translation mechanism 30 and the Y-axis translation mechanism 40 cooperate to drive the laser head 50 to move along a preset trajectory to complete the cutting of the fabric. Through this series of automated actions, the equipment realizes full-process automation from feeding and pulling to cutting, replacing the traditional inefficient manual pulling method and significantly improving the efficiency and automation level of the bed frame paper mold cutting operation.

[0021] The operating table 11 has several air holes 111 penetrating its upper and lower surfaces. A bottom cover 12 covering all the air holes 111 is located at the bottom of the operating table 11. An air extraction chamber 121 is formed inside the bottom cover 12, and the air holes 111 communicate with the air extraction chamber 121. An air extraction port 122, connected to the air extraction chamber 121, is located at the bottom of the bottom cover 12 and is connected to a vacuum device via a pipe. When the fabric is pulled and laid flat on the operating table 11, the vacuum device is activated, extracting air from the air extraction chamber 121 of the bottom cover 12 through the air extraction port 122, creating a negative pressure environment. This negative pressure is evenly applied to the lower surface of the fabric through the air holes 111 on the operating table 11, generating a strong adsorption force that firmly fixes the fabric in place. This design effectively prevents the fabric from shifting or wrinkling during high-speed cutting by the laser head 50, especially for thin or smooth materials, ensuring the accuracy of the cutting trajectory and edge quality. The feeding mechanism 20 also includes an upper conveying roller 23 and a lower conveying roller 24, which are rotatably mounted between two mounting plates 21, forming an adjustable conveying gap between them. This conveying gap is located between the operating table 11 and the feeding roller 22. Before or during clamping by the clamping mechanism 60, the upper conveying roller 23 and the lower conveying roller 24 can rotate towards each other, actively drawing the fabric out from the feeding roller 22 and conveying it a certain distance, allowing it to reach the predetermined clamping position more smoothly, and assisting in maintaining fabric tension during the traction process. This achieves auxiliary traction and initial tensioning during the feeding process, preventing the fabric from sagging due to its own weight in the area between the feeding roller 22 and the operating table 11. In the design of the clamping mechanism 60, the clamping gap 601 formed between the upper clamping plate 63 and the lower clamping plate 65 is specially designed as a figure-eight shaped guide structure at the end near the feeding mechanism 20. When the second y-axis drive device 61 drives the vertical plate 62 and the upper clamping plate 63 and the lower clamping plate 65 on it to move towards the corner of the fabric, even if there is a slight deviation in the initial positioning, this flared structure can easily guide the edge of the fabric to slide in and reach the accurate clamping position. This structure significantly reduces the stringent requirements on the initial positioning accuracy of the clamping mechanism 60 and improves the success rate and efficiency of the automatic clamping action. At the same time, elastic pads are provided on the lower surface of the upper clamping plate 63 and the upper surface of the lower clamping plate 65. When the z-axis drive device 64 pushes the lower clamping plate 65 up to clamp the fabric, the elastic pads deform, which increases the friction to prevent the fabric from slipping off and adapts to changes in fabric thickness, avoiding indentations or damage that may be caused by rigid clamping. This ensures the firmness of the clamping and the integrity of the fabric surface. The x-axis drive device 31, the first y-axis drive device 41, and the second y-axis drive device 61 employ high-precision gear and rack transmission devices or ball screw transmission devices. These devices are responsible for driving the x-axis sliding seat 32, the y-axis sliding seat 42, and the vertical plate 62 of the clamping mechanism 60 to perform precise linear motion. This ensures smooth movement and accurate positioning when the clamping mechanism 60 pulls the fabric and the laser head 50 for cutting, thereby ensuring the dimensional accuracy of the final cut pattern. The z-axis drive device 64, used to drive the lower clamping plate 65 to rise and fall, uses a cylinder or electric push rod. These provide fast and powerful linear motion, ensuring that the lower clamping plate 65 can quickly and reliably perform clamping and releasing actions. This guarantees the response speed and reliability of the clamping and releasing process. Finally, the mounting height of the laser head 50 on the y-axis sliding seat 42 is designed to be adjustable. Operators can manually or via a program fine-tune the focal position of the laser head 50 according to the thickness and material properties of different fabrics. This ensures that the laser energy is always precisely focused on the fabric surface, thereby achieving optimal cutting results and enhancing the equipment's adaptability to diverse processing needs.
