[0004] However, the above-mentioned device is suitable for sewing rubber bands onto fabric, but it cannot be used to sew rubber bands together, and the sewn ends of the rubber bands are difficult to keep overlapping during the sewing process. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rubber band sewing device that uses a docking device to dock the ends of two sets of rubber bands that need to be sewn together, a fixing device to help fix the end areas of the rubber bands to prevent them from shaking or shifting during docking and sewing, thus affecting normal sewing operations, and a limiting device to limit the position of the rubber bands on the fixing device to adjust the overlap of the sewing areas between the two sets of rubber bands, thereby improving the practicality of the device.

[0006] This utility model discloses a rubber band sewing device, comprising a docking device, a fixing device, and a limiting device. The fixing device is installed on the docking device, and the limiting device is installed on the fixing device. The docking device connects the ends of two sets of rubber bands to be sewn together. The fixing device provides auxiliary fixation to the end areas of the rubber bands to prevent them from shaking or shifting during docking and sewing, thus affecting normal sewing operations. The limiting device limits the position of the rubber bands on the fixing device to adjust the overlap of the sewing areas between the two sets of rubber bands, thereby improving the practicality of the device.

[0007] Preferably, the docking device includes a carrier box, a reducer, a motor, a bidirectional lead screw, a transverse platform, and horizontal limiting rods. The reducer is mounted on the left end face of the carrier box, and the motor is mounted on the reducer. A slotted hole is provided on the upper end face of the carrier box. A bidirectional lead screw and two sets of horizontal limiting rods are horizontally installed inside the carrier box. The bidirectional lead screw is located below the slotted hole in the carrier box itself, and the two sets of horizontal limiting rods are located on the front and rear sides of the bidirectional lead screw, respectively. The output end of the reducer is connected to the bidirectional lead screw. The two sets of transverse platforms are respectively fitted onto the left and right sides of the bidirectional lead screw by nuts. The two sets of transverse platforms are symmetrical about the center position of the bidirectional lead screw, and the two sets of horizontal limiting rods pass through the front and rear of the two sets of transverse platforms. The motor is turned on and the power is transmitted to the bidirectional lead screw through the reducer to drive the bidirectional lead screw to rotate. The rotating bidirectional lead screw, in conjunction with the nut, drives the two sets of transverse platforms to move towards or away from each other, so as to complete the automatic docking of the rubber band with the fixing device. The two sets of horizontal limiting rods limit the transverse movement of the transverse platforms, reduce the vibration amplitude of the transverse platforms during the transverse movement, and improve the practicality of the device.

[0008] Preferably, the fixing device includes a bearing platform, a gantry, an electric cylinder, and a pressure plate. The bearing platform is connected to the upper end of the transverse platform, the gantry is installed on the upper end of the bearing platform, and the electric cylinder is installed on the upper end of the gantry. The moving end of the electric cylinder extends through the upper end of the gantry into the gantry and connects with the pressure plate. The bearing platform supports the end area of ​​the rubber band, and the electric cylinder is controlled to extend and drive the pressure plate to press the end area of ​​the rubber band downward, so that the docking device can drive the rubber band to move and dock, thus improving the practicality of the device.

[0009] Preferably, the device also includes a pressure switch and vertical limiting rods. The moving end of the electric cylinder is connected to the upper end face of the pressure plate via the pressure switch. A set of vertically upward limiting rods is provided on the left and right sides of the upper end face of the pressure plate. The upper parts of both sets of vertical limiting rods extend through the upper end face of the gantry to the upper side of the gantry. The pressure switch monitors the pressure on the moving end of the electric cylinder to prevent excessive pressure from causing indentations on the surface of the rubber band. The two sets of vertical limiting rods limit the lifting and lowering process of the pressure plate to prevent the pressure plate from tilting during the descent, thus improving the practicality of the device.

[0010] Preferably, the limiting device includes a rotating arm, a geared motor, a sleeve, an L-shaped baffle, and connecting rods.

A set of connecting rods is provided on the left side of the front and rear end faces of the L-shaped baffle. The two sets of connecting rods can be inserted into the corresponding two sets of sleeves. Multiple sets of fastening bolts are installed on the side of the sleeve. The rotating arm is driven to rotate by the geared motor, thereby causing the L-shaped baffle to rotate. The L-shaped baffle limits the position of the rubber band end inserted into the gantry. The position of the rubber band end is adjusted by adjusting the position of the connecting rod in the sleeve. The position of the connecting rod in the sleeve is limited by the fastening bolt. After the rubber band is placed into the gantry and fixed, the docking device is controlled to move the two sets of rubber bands towards each other. At the same time, the L-shaped baffle on one side of the gantry is rotated to the upper side of the gantry, and the other L-shaped baffle is raised at a slight angle without the rubber band falling off the L-shaped baffle. After the two sets of rubber bands overlap within a certain range, the L-shaped baffle raised at a slight angle is controlled to continue to rotate upward, so that the upper rubber band is placed on the other set of rubber bands to facilitate sewing and connection, thus improving the practicality of the device.

[0011] Preferably, the device also includes a sewing frame, a support plate, and limit switches. A sewing frame is installed in the middle of the upper surface of the carrier box, and a sewing machine that can slide back and forth is provided on the upper surface of the sewing frame. A support plate is provided in the middle of the upper surface of the carrier box, and a set of limit switches is installed in the middle of both the front and rear ends of the support plate. The sewing machine on the sewing frame sews the rubber bands together, the support plate provides auxiliary support for the sewing area of ​​the rubber bands, and the two sets of limit switches limit the movement of the carrier platform to prevent damage to the equipment from collisions, thereby improving the protective and practical functions of the device.

[0012] Preferably, it also includes rubber strips, with multiple sets of rubber strips provided on the lower end surface of the pressure plate; the multiple sets of rubber strips reduce the damage to the surface of the rubber band caused by the pressure plate, provide protection for the compressed part of the rubber band, and improve the practicality of the device.
