Description

Technical Field

[0001] This utility model relates to the field of bed sheet production technology, specifically a cutting machine for bed sheet production. Background Technology

[0002] In the modern home textile industry, bed sheets are daily necessities, and their production efficiency and quality directly affect the market competitiveness of enterprises. With the continuous growth of consumer demand for diversified bed sheet styles and specifications, the cutting process in the bed sheet production process has become particularly critical. The cutting process needs to ensure that the bed sheet size is accurate and the edges are neat.

[0003] Traditional bed sheet cutting equipment mostly uses a flat-lay cutting method, where the bed sheet is laid completely flat on the cutting machine table, and cutting is performed along a preset trajectory using cutting blades or laser cutting heads. Due to the large size of bed sheets, laying them completely flat requires a lot of space on the cutting machine table, resulting in a large overall size of the cutting equipment and a large footprint. This is especially problematic for small and medium-sized factories with limited production space, as the space occupied by the equipment severely restricts the factory's production layout and capacity expansion. In addition, during the flat-lay cutting process, longer sheets tend to droop and drag on the ground, easily accumulating dust and stains in the complex environment of the production workshop, affecting the cleanliness of the sheets and the quality of the finished product. Furthermore, keeping the sheets flat requires manual straightening and fixing, which is cumbersome. Any wrinkles or looseness on the fabric surface can lead to unevenness in the cut area, reducing cutting accuracy.

[0004] Therefore, developing a cutting equipment for bed sheet production that can optimize cutting space and improve cutting accuracy has become an urgent technical problem to be solved in the home textile production field. Utility Model Content

[0005] The purpose of this invention is to provide a cutting machine for bed sheet production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting machine for bed sheet production, comprising a cutting machine table, a laser cutting head disposed above the cutting machine table, a folding cutting mechanism disposed on the upper part of the cutting machine table, the folding cutting mechanism comprising a fabric stretching roller, an annular slitting slide, and a corner positioning component, the fabric stretching roller being rotatably connected above the table surface of the cutting machine table, the annular slitting slide being fixed inside the cutting machine table, the corner positioning component being disposed in a groove on the table surface of the cutting machine table, the laser cutting head being slidably connected to the inner ring of the annular slitting slide, and a clearance opening being provided on the table surface of the cutting machine table.

[0007] Preferably, the corner positioning component includes a straightening slide, which is slidably connected in the table groove of the cutting machine table. A clamping cylinder is fixed at the lower end of the straightening slide, a second pressure plate is provided above the straightening slide, and a first pressure plate is provided between the straightening slide and the second pressure plate.

[0008] Preferably, the output end of the pressing cylinder passes through the straightening slide and the first pressure plate and is fixed to the bottom of the second pressure plate, and a fixing block is fixed between the output end of the pressing cylinder and the first and second pressure plates.

[0009] Preferably, the bottom of the straightening slide is fixed with an adjustment guide block, and the table surface of the cutting machine is provided with an adjustment groove, and the adjustment guide block is slidably connected in the adjustment groove.

[0010] Preferably, anti-slip pads are fixed on one side surface of the straightening slide, the first pressure plate, and the second pressure plate, and clamping openings are provided between the straightening slide and the first pressure plate, and between the second pressure plate and the first pressure plate.

[0011] Preferably, a gap is provided between the fabric stretching roller and the cutting machine table surface, and an annular slitting slide is provided inside the annular slitting slide for the laser cutting head to slide.

[0012] This utility model provides a cutting machine for bed sheet production, which has the following advantages compared with the prior art:

[0013] The folding and cutting mechanism allows for concentrated cutting of both sides of the sheet by folding it and then sliding the laser cutting head along the circular cutting track. This significantly reduces the cutting range compared to traditional flat cutting, effectively optimizing the table size and reducing the equipment footprint. It is especially suitable for factories with limited production space, improving space utilization. The folded sheet also reduces its length, preventing the sheet from becoming too long and getting dirty at one end during the cutting process.

[0014] The corner positioning components precisely clamp adjacent corners of the sheet, and the overlapping stretch rollers provide support from the sheet's layers, straightening the sheet from both sides. Simultaneously, the straightening slide, through the adjustment guide block and adjustment groove, allows for flexible adjustment of the front-to-back distance of the sheet corners, achieving front-to-back straightening. Applying tension in multiple directions effectively eliminates wrinkles, ensures the straightness of the cut areas, and significantly improves cutting accuracy and finished product yield.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a cutting machine for bed sheet production, including a cutting machine table 1. A laser cutting head 13 is arranged above the cutting machine table 1. The laser cutting head 13 slides along the inner circle of the annular slitting slide 4 and cuts the two sides of the folded bed sheet with a laser beam to achieve an efficient and flat slitting effect. A folding and cutting mechanism 2 is arranged on the upper part of the cutting machine table 1. The folding and cutting mechanism 2 includes a fabric stretching roller 3, an annular slitting slide 4, and a corner positioning component 5. The fabric stretching roller 3 is rotatably connected above the table surface of the cutting machine table 1. The bed sheet is guided through the gap between the roller and the table to achieve the folding of the bed sheet, so that the bed sheet is laid flat on the table in a double layer. The annular slitting slide 4 is fixed inside the cutting machine table 1. The corner positioning component 5 is set in the table groove of the cutting machine table 1. The laser cutting head 13 is slidably connected to the inner ring of the annular slitting slide 4. The table surface of the cutting machine table 1 is provided with a clearance opening 15. The annular movement path concentrates the cutting range, reduces the table size of the cutting machine table 1, reduces the equipment footprint, and avoids the problem of the bed sheet dragging and getting dirty due to being too long.

[0022] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the corner positioning component 5 includes a straightening slide 6, which is slidably connected in the table groove of the cutting machine table 1. A pressing cylinder 11 is fixed at the lower end of the straightening slide 6, and a second pressure plate 8 is provided above the straightening slide 6. A first pressure plate 7 is provided between the straightening slide 6 and the second pressure plate 8. The output end of the pressing cylinder 11 passes through the straightening slide 6 and the first pressure plate 7 and is fixed at the bottom of the second pressure plate 8. A fixing block 12 is fixed between the output end of the pressing cylinder 11, the first pressure plate 7, and the second pressure plate 8. The first pressure plate 7 serves as an intermediate layer and forms an upper and lower clamping structure with the straightening slide 6 and the second pressure plate 8 to fix the two corners of the bed sheet respectively. The anti-slip pad 9 increases the friction of the contact surface and prevents the bed sheet from sliding.

[0023] Straighten left and right: The folded fabric stretching roller 3, in conjunction with the clamping force, straightens the left and right sides of the bed sheet.

[0024] Straightening front and back: By sliding the adjustment guide block 10 in the adjustment groove 16, the front and back positions of the corner positioning component are adjusted to straighten the front and back sides of the bed sheet and ensure that the cut parts are straight.

[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the bottom of the straightening slide 6 is fixed with an adjustment guide block 10, and the table surface of the cutting machine table 1 is provided with an adjustment groove 16. The adjustment guide block 10 is slidably connected in the adjustment groove 16. Anti-slip pads 9 are fixed on one side surface of the straightening slide 6, the first pressure plate 7, and the second pressure plate 8. Clamping openings are provided between the straightening slide 6 and the first pressure plate 7, and between the second pressure plate 8 and the first pressure plate 7. Through the clamping structure of the straightening slide 6, the first pressure plate 7, and the second pressure plate 8, the two adjacent corners of the bed sheet are fixed, achieving precise positioning and preventing the bed sheet from shifting during cutting.

[0026] Further as Figure 1 As shown, it is worth noting that there is a gap between the fabric stretching roller 3 and the table surface of the cutting machine table 1, and the annular slitting slide 4 has an annular slide 14 for the laser cutting head 13 to slide inside.

[0027] The solution has the following working process: Before use, one end of the sheet to be trimmed passes through the gap between the folding stretch roller 3 and the cutting machine table 1. Then, one corner of the sheet is positioned and clamped between the straightening slide 6 and the first pressure plate 7. Then, the opposite end of the sheet passes through the top of the folding stretch roller 3 and is finally fixed between the second pressure plate 8 and the first pressure plate 7. In this way, the corner positioning component 5 can accurately position the two adjacent corners of the sheet, so that the sheet is folded and distributed on the cutting machine table 1. The laser cutting head 13 can slide around the annular cutting slide 4 to achieve concentrated cutting of both sides of the sheet. The cutting method after folding the sheet results in a smaller cutting range, which can optimize the table size of the cutting machine table 1 and reduce the floor space occupied. At the same time, the length of the sheet shrinks after folding, which also prevents the other end of the sheet from dragging and getting dirty during cutting due to excessive length.

[0028] The corner positioning component 5 positions the two corners of the bed sheet, and together with the fabric stretching roller 3, it applies support force from the interlayer of the bed sheet to straighten the left and right sides of the bed sheet. By using the adjustment guide block 10 at the lower end of the straightening slide block 6 to slide along the adjustment groove 16, the front and back distance of the corners of the bed sheet positioned by the corner positioning component 5 can be adjusted to straighten the front and back sides of the bed sheet. Applying tension in multiple directions (front, back, left, and right) during the cutting of the bed sheet can ensure the straightness of the cut parts of the bed sheet, thereby reducing the impact of wrinkles on the straightness quality of the cut bed sheet.
