Description

Technical Field

[0001] The invention relates to the field of bed sheet production, and in particular to a bed sheet production and winding device. Background Art

[0002] During the production process of bed sheets, a winding device is usually required to wind up the bed sheet fabric, and the fabric is cut after being rolled to a certain length so that the bed sheet fabric can be transported in rolls. In the existing bed sheet fabric winding device, the connection between the winding roller and the fabric is mainly achieved through the friction force during winding. Since the friction between the fabric and the winding roller is insufficient at the beginning of winding, idling is likely to occur between the winding roller and the fabric, thereby affecting the normal winding of the fabric. Moreover, after being rolled to a certain length, the fabric is often required to be cut manually, and manual cutting is likely to make the ends of the fabric uneven, and the winding length is uneven, and the diameter of each roll of fabric is different, affecting the subsequent production process. Summary of the invention

[0003] The object of the present invention is to provide a bed sheet production and winding device to overcome the above-mentioned defects in the prior art.

[0004] A bed sheet production and winding device according to the present invention comprises a base, two symmetrically arranged supports are arranged on the upper side of the base, a winding roller is detachably connected between the two supports, a through groove penetrating the circumferential wall of the winding roller is opened, a leveling rod abutting against the outer periphery of the winding roller is arranged on the lower side of the winding roller, connecting seats are rotatably connected at both ends of the leveling rod, a damping rod is fixed between the connecting seat and the base, a positioning rod is arranged on the lower side of the leveling rod, an adjusting seat is fixed on the upper end surface of the base, a lifting rod is slidably connected in the adjusting seat, both ends of the positioning rod are rotatably connected to the upper ends of two lifting rods, a threaded rod is connected to the inner thread of the lifting rod, the lower end of the threaded rod is rotatably connected to the base, a cutting knife is fixed on the outer periphery of the positioning rod, and the cutting knife can abut against the outer periphery of the leveling rod.

[0005] Through the above-mentioned technical scheme, a through groove is opened on the outer peripheral wall of the winding roller, so that one end of the sheet fabric can pass through the through groove, so as to facilitate the fixation between the sheet fabric and the winding roller, ensuring the firmness of the connection between the fabric and the winding roller when the winding roller is winding the fabric. When the sheet fabric is rolled up to a certain diameter, the fabric abuts against the cutting knife, and the fabric is cut by the cutting knife, ensuring that the rolled-up length of the fabric is consistent each time the fabric is cut. At the same time, the height of the cutting knife can be adjusted by the rotation of the threaded rod, thereby realizing the adjustment of the diameter of the fabric when it is rolled up.

[0006] Furthermore, a support rod is fixed between the support and the base, a rotating shaft is rotatably connected in the support, a spring cavity is opened in the rotating shaft, the spring cavity is opened at one end close to the winding roller, a telescopic rod is slidably connected in the spring cavity, a spring is fixed between the end of the telescopic rod away from the winding roller and the bottom wall of the spring cavity, a square recessed hole is opened on the end surface of the telescopic rod close to the winding roller, a plug-in rod is slidably connected in the square recessed hole, a support block is fixed on one end of the plug-in rod close to the winding roller, a connecting block is rotatably connected in the end of the winding roller, the outer periphery of the connecting block is frictionally fitted with the inner wall of the winding roller, and the connecting block is fixed to an adjacent support block.

[0007] Through the above technical solution, the telescopic rod slides along the spring cavity to achieve the separation of the telescopic rod and the plug-in rod, thereby facilitating the disassembly between the telescopic rod and the plug-in rod, and facilitating the disassembly and assembly between the winding roller and the support.

[0008] Furthermore, a circle of annular protrusions is fixedly provided on the outer circumference of one end of the telescopic rod close to the support block, and the diameter of the annular protrusions is larger than the diameter of the support block.

[0009] Through the above technical solution, the provision of the annular protrusion is conducive to pushing the telescopic rod to slide along the spring cavity.

[0010] Furthermore, the distance between the annular protrusion and the support is greater than the length of the plug-in rod, the distance between the end surface of the telescopic rod away from the winding roller and the bottom wall of the spring chamber is greater than the distance between the annular protrusion and the support, and the two plug-in rods are located between the two supports.

[0011] The above technical solution ensures that when the annular protrusion slides to abut against the support, the plug-in rod is completely separated from the direction recessed hole.

[0012] Furthermore, a fixing rod is fixed to the end face of one side of the connecting block away from the supporting block, and the fixing rod is composed of two straight parts and two arc-shaped clamping parts. The two straight parts are symmetrically arranged and parallel to each other, and there is a gap between the straight parts and the inner wall of the winding roller. The two arc-shaped clamping parts are symmetrically arranged and respectively connected between the two ends of the two straight parts. The arc-shaped clamping parts are in a circular arc shape and abut against the inner wall of the winding roller. The distance between the end faces of the two fixing rods is less than the length of the through groove.

[0013] Through the above technical solution, after one end of the cloth passes through the through slot and enters the winding roller, the fixing rod is rotated so that the arc-shaped clamping part and the inner wall of the winding roller clamp the end of the cloth, thereby realizing rapid fixation between the cloth and the winding roller, while ensuring the firmness of the connection between the cloth and the winding roller.

[0014] Furthermore, one of the rotating shafts extends out of the support in a direction away from the winding roller, and a first driven wheel is fixed on its outer periphery, a motor is fixed on the upper end surface of the base, a first driving wheel is fixed on the output shaft of the motor, and a first belt is connected to the motor and the first driving wheel.

[0015] Through the above technical solution, the motor drives the rotating shaft to rotate through the first belt, so that the winding roller can maintain a uniform rotation speed, thereby realizing the winding of the cloth.

[0016] Furthermore, a pulley cavity is opened in the base, the lower end of the threaded rod extends downward into the pulley cavity, a second driven wheel is fixed to the lower end of the threaded rod, a second driving wheel is rotatably connected in the upper end surface of the base, the lower end of the second driving wheel extends downward into the pulley cavity and is located between the two threaded rods, the upper end of the second driving wheel extends upward to the upper side of the base, a knob is fixed to the upper end of the second driving wheel, a rotating rod is fixed to the lower end of the second driving wheel, the diameter of the rotating rod is larger than the diameter of the second driven wheel, and a second belt is dynamically connected between the rotating rod and the two second driven wheels.

[0017] Through the above technical solution, by turning the knob, the two threaded rods can be rotated simultaneously, thereby achieving adjustment of the height of the positioning rod.

[0018] The beneficial effects of the present invention are as follows: a through groove is provided on the outer peripheral wall of the winding roller, so that one end of the bed sheet fabric can pass through the through groove, so as to facilitate the fixation between the bed sheet fabric and the winding roller, ensuring the firmness of the connection between the fabric and the winding roller when the winding roller is winding the fabric; when the bed sheet fabric is wound to a certain diameter, the fabric abuts against the cutting knife, and the fabric is cut by the cutting knife, ensuring that the wound length of the fabric is consistent each time the fabric is cut; and at the same time, the height of the cutting knife can be adjusted by the rotation of the threaded rod, thereby realizing the adjustment of the diameter size when the fabric is wound up.
