Description

Technical Field

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

[0002] Bed sheets are fabrics placed on mattresses to protect them and improve comfort. Bed sheets are typically made of various materials, including cotton, linen, polyester, and blended fabrics, and come in different textures, colors, and patterns.

[0003] Existing bed sheets often have a lining strip wrapped around the edges during the manufacturing process to protect the edges or enhance the sheet's appearance, as shown in the instruction manual. Figure 7 As shown, in existing bed sheet production equipment, the connection between the lining strip and the edge of the bed sheet is prone to misalignment, and the folding between the bed sheet and the lining strip sometimes deviates. As a result, the aesthetics and quality of the bed sheet after the lining strip and the edge of the bed sheet are sewn together cannot meet the needs of personnel. Therefore, it still has certain shortcomings.

[0004] In conclusion, it is necessary to invent a new type of bed sheet production line. Utility Model Content

[0005] Therefore, this utility model provides a new type of bed sheet production line to solve the problems in existing bed sheet production equipment, such as the easy misalignment between the lining strip and the edge of the bed sheet, and the occasional deviation in the folding of the edge between the bed sheet and the lining strip.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel bed sheet production line, comprising a feeding mechanism for conveying fabric, a lower cutting structure for cutting fabric on the right side of the feeding mechanism, and a lining sewing mechanism for sewing fabric and lining strips between the feeding mechanism and the lower cutting structure.

[0007] Preferably, the feeding mechanism includes a first frame, a fabric feeding roller for storing fabric is provided on the bottom left side of the outer wall of the first frame, and a fabric guide is installed on the side wall of the first frame above the fabric feeding roller.

[0008] Preferably, a fabric splicing machine is installed on the first frame between the fabric feeding roller and the fabric guide, and an edge trimming knife is installed on the first frame to the right of the fabric guide.

[0009] Preferably, the lining strip sewing mechanism includes a second frame, with a lining strip storage roller for placing lining strips installed at the bottom of the outer wall of the second frame, and a sensor for detecting the passage of lining strips installed on the second frame and to the left of the lining strip storage roller.

[0010] Preferably, a guide rod for adjusting the direction of the lining strip is fixed at the bottom of the outer wall of the second frame and at the end away from the lining strip storage roller from the sensor, and a pre-folding mechanism for pre-folding the fabric and lining strip is provided on the left side of the outer wall of the second frame and above the guide rod.

[0011] Preferably, the second frame, located on the right side of the pre-folding mechanism, is provided with a double eyelid folding tube for folding the fabric and lining strip, and the bottom right side of the outer wall of the double eyelid folding tube is provided with a lower folding tube for support by the fabric and lining strip.

[0012] Preferably, a sewing machine is installed on the top right side of the outer wall of the second frame. The sewing machine is located on the right side of the double eyelid lifting tube and is at the same horizontal position as the double eyelid lifting tube.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the fabric and lining strip are set separately, and during their conveying process, they are pre-folded by a pre-folding mechanism. Then, the lining strip and fabric are fixed together in a specific shape by the cooperation of the double eyelid pull tube and the lower folding pull tube. Subsequently, they are sewn together by a sewing machine. As can be seen from the above method, this invention can align and fold the fabric and lining strip before sewing by the cooperation of the pre-folding mechanism, the double eyelid pull tube, and the lower folding pull tube. This can effectively prevent the two from deviating during the sewing process, thus making it more convenient for users to use. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figures 1-7 This utility model provides a novel bed sheet production line, including a feeding mechanism 100 for conveying fabric. The feeding mechanism 100 includes a first frame. A fabric feeding roller 110 for storing fabric is provided on the bottom left side of the outer wall of the first frame. A fabric guide 120 is installed on the side wall of the first frame above the fabric feeding roller 110 to prevent the fabric from deviating during the conveying process. A fabric splicing machine 130 is installed on the first frame between the fabric feeding roller 110 and the fabric guide 120 to facilitate personnel to ensure normal fabric conveying when changing fabric rolls. An edge trimming knife 140 is installed on the first frame to the right of the fabric guide 120 to trim the excess part of the fabric edge before sewing the interfacing.

[0025] A lower cutting structure 200 for cutting fabric is provided on the right side of the feeding mechanism 100. Between the feeding mechanism 100 and the lower cutting structure 200 is a lining strip sewing mechanism 300 for sewing fabric and lining strips. The lining strip sewing mechanism 300 includes a second frame. A lining strip storage roller 310 for placing lining strips is installed at the bottom of the outer wall of the second frame. The lining strip storage roller 310 can be connected to the second frame via a rotating shaft. A sensor 320 for detecting the passage of lining strips is installed on the second frame to the left of the lining strip storage roller 310. The sensor 320 is used to detect whether the lining strip is being conveyed normally. The bottom of the outer wall of the second frame, away from the sensor 320, is located away from the lining strip storage roller. One end of 310 is fixed with a guide rod 330 for adjusting the direction of the lining strip. A pre-folding mechanism 340 for pre-folding the fabric and lining strip is located on the left side of the outer wall of the second frame, above the guide rod 330. This pre-folding mechanism 340 can pre-fold the fabric and lining strip during the conveying process. On the right side of the pre-folding mechanism 340, a double-eyelid pull tube 350 for folding the fabric and lining strip is located on the second frame. A lower folding pull tube 351 for supporting the fabric and lining strip is located on the bottom right side of the outer wall of the double-eyelid pull tube 350. When the edge of the fabric and the lining strip pass through the double-eyelid pull tube 350, the structure of the double-eyelid pull tube 350 allows them to be folded as shown in the attached instruction manual. Figure 7 As shown in the figure, a sewing machine 360 ​​is installed on the top right side of the outer wall of the second frame. The sewing machine 360 ​​is located on the right side of the double eyelid tube 350. The sewing machine 360 ​​and the double eyelid tube 350 are at the same horizontal position. The sewing machine 360 ​​can then sew and fix the folded fabric and lining strip, so that the lining strip can be fixed on the edge of the fabric.

[0026] The usage process of this utility model is as follows: First, the operator places the fabric on the fabric feeding roller 110 and the lining strip on the lining strip storage roller 310. The fabric is then conveyed by the conveying roller on the first frame. The fabric correction device 120 prevents the fabric from deviating during the conveying process. After trimming by the trimming knife 140, the fabric enters the second frame. At the same time, the lining strip is pulled out from the lining strip storage roller 310 by the conveying roller, and then passes through the sensor 320 and the guide rod 330 in sequence, and is positioned at the pre-folding mechanism 340. The fabric is brought into contact with and pre-folded, and then conveyed together with the lining strip until it reaches the double eyelid pull tube 350. The double eyelid pull tube 350 can work with the lower folding pull tube 351 to fold the fabric and lining strip, and then convey them to the sewing machine 360 ​​for sewing and fixing. The fixed fabric and lining strip will enter the lower cutting structure 200, which can cut the fabric and lining strip through the electric heating wire cutting mechanism. Then, the fabric is dragged into the output assembly line by the material pulling clamp, and flows out after accumulating a certain quantity.

[0027] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
