Description

Technical Field

[0001] This utility model relates to the field of bed cover sewing machine technology, specifically a bed cover sewing machine with multi-axis adjustable presser foot stitch. Background Technology

[0002] Currently, during medical examinations and nursing care, secretions and disinfectant solutions can contaminate beds, requiring one-time use and disinfection for each patient, significantly increasing the burden on hospitals. Using disposable bed sheets would greatly improve work efficiency and reduce the burden on hospitals, as disposable sheets can be changed directly after examinations and nursing care. Bed sheet machines are equipment used to process bed sheets. Through a series of mechanical devices and processes, raw materials (such as fabric) are cut, sewn, folded, and edge-sealed to ultimately produce finished bed sheets.

[0003] The existing Chinese utility model patent with publication number CN214858501U discloses a bed cover machine, including a side forming mechanism, a deep folding mechanism, a corner sealing and cutting mechanism, and a cutting mechanism. The side forming mechanism includes a side folding component, an elastic band guiding component, a sealing component, and a first traction component. The deep folding mechanism includes a folding component, which includes a horizontally arranged second guide roller, a deep folding plate, and a lower support plate. The second guide roller is located below the deep folding plate. The deep folding plate is divided into a front folding plate and a rear folding plate. The rear folding plate is trapezoidal and inclined, while the front folding plate is square and horizontal. The lower support plate is located below the front folding plate, and there is a gap between the two. The corner sealing and cutting mechanism includes a corner sealing and cutting component and a second traction component. The material sequentially undergoes side forming, deep folding, and corner sealing and cutting, and is finally cut into disposable unit bed covers, realizing the automatic processing of bed covers.

[0004] While the aforementioned bed cover machine solves the problem of the lack of equipment for processing disposable bed covers, existing bed cover machines have poor adjustment effects when sewing the presser foot stitches, which can easily affect the sewing effect due to the fabric bag being too loose. Utility Model Content

[0005] The purpose of this invention is to overcome the problem of poor adjustment effect in the existing technology and to provide a bed cover sewing machine with multi-axis adjustable presser foot thread.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-axis adjustable presser foot sewing machine for bed sheet covers includes:

[0008] A support plate has two support grooves fixedly installed on both sides, the support grooves being U-shaped. A guide roller is movably connected to the front part of each support groove. Two electric lifting grooves are fixedly installed on both sides of the top of the support plate, and two drive motors are fixedly installed on both sides of the top of each electric lifting groove. A lifting plate is movably connected inside each electric lifting groove, and a fixing groove is fixedly installed inside the lifting plate. An adjusting groove is fixedly installed inside the fixing groove, and a lifting block is movably connected inside the adjusting groove. Two sensor heads are fixedly installed on the upper and lower sides inside the adjusting groove. A support spring is fixedly installed at the bottom of the lifting block, and a connecting block is fixedly installed on one side of the lifting block. A support roller is movably connected to one side of the connecting block.

[0009] In a preferred embodiment, two drive devices are fixedly installed on both sides of the top of the support groove, and a winding roller is movably connected to the top of the drive device. The winding roller is a structure used to wind up the cloth bag.

[0010] In a preferred embodiment, a bed cover machine body is fixedly installed on one side of the support groove, and two support blocks are fixedly installed on both sides of the bed cover machine body. The support blocks are structures used for support.

[0011] In a preferred embodiment, a connecting roller is movably connected to one side of the support block, and two hot press plates are fixedly installed on both sides of the interior of the bed cover machine body. The hot press plates are structures used for hot pressing and sewing the fabric.

[0012] In a preferred embodiment, a support frame is fixedly installed on one side of the top of the bed cover machine body. The support frame is U-shaped and is a support structure.

[0013] In a preferred embodiment, two winding devices are fixedly installed on both sides of one side of the support frame. The winding devices are structures used to support the elastic band.

[0014] In a preferred embodiment, two mounting motors are fixedly installed on both sides of the support frame, and a hot press roller is movably connected to one side of each mounting motor. The hot press roller is a structure used for sewing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This multi-axis adjustable presser foot stitching bed cover machine guides the fabric through guide rollers inside two support grooves, which in turn support the fabric bag. The tightness of the fabric can be adjusted by the contraction of the support spring at the bottom of the lifting block inside the adjustment groove. When the fabric is too tight, the spring contraction adjusts the tightness. When the fabric is too loose or too tight, the lifting block in the adjustment groove contacts the upper or lower sensor head. Contact with the upper sensor head causes the lifting plate to move upward within the groove via the operation of the electric lifting groove; contact with the lower sensor head causes the lifting plate to move downward within the groove. This avoids the problem of excessively loose or tight fabric affecting the presser foot stitching and subsequent processing results, improving the practicality and convenience of this multi-axis adjustable presser foot stitching bed cover machine.

The guide rollers 12 inside the two support grooves 11 can guide the fabric, and the support rollers 25 can support the fabric. The lifting block 21 can be wrapped by the adjustment groove 2. The tension of the fabric is automatically adjusted by the contraction of the support spring 23 at the bottom of the lifting block 21. When the fabric is too loose or too tight, the lifting block 21 can contact the two sensor heads 22 on the upper and lower sides inside the adjustment groove 2 through the contraction or extension of the support spring 23. When it contacts the upper sensor head 22, the drive motor 14 can drive the electric lifting groove 13 to move its internal lifting plate 15 upward until the lifting block 21 is in place. When the lifting block 21 contacts the lower sensor head 22 after detaching from the top sensor head 22, the electric lifting groove 13 can be driven by the drive motor 14 to move its internal lifting plate 15 downward until the lifting block 21 detaches from the bottom sensor head 22. This avoids the problem of the fabric being too loose or too tight, which affects the sewing effect of the fabric presser foot line. This improves the practicality and convenience of the multi-axis adjustable presser foot line sewing bed cover machine. The connecting roller 32 can be supported by the support blocks 31 on both sides of the bed cover machine body 3. The connecting roller 32 can guide the fabric. The two winding devices 35 can be supported by the support frame 34. The winding devices 35 can support the elastic band. The operation of the installed motor 36 can make the hot pressure roller 37 rotate, thereby performing hot pressure sewing on the presser foot line. This improves the practicality and convenience of the multi-axis adjustable presser foot line sewing bed cover machine.
