Description

Technical Field

[0001] The utility model belongs to the technical field related to hat production, and particularly relates to an edge locking machine for hat production. Background Art

[0002] The hat edge-locking machine is a device specially used for edge-locking of hats. It can sew the fabric on the edge of the hat to make it more firm and beautiful. This machine usually has the characteristics of high speed, firmness, flatness, and easy removal of stitches. It is suitable for using thick thread to wrap the edge of the fabric. After opening, it is flat and firm, with a triangular stitch on one side and a straight stitch on the other side. However, the following disadvantages still exist in the actual edge-locking work of the hat:

[0003] 1. When the hat is edge-locked, in the actual production process, the brims of hats with different thicknesses need to be edge-locked. When the brims of the hats are directly set between the upper pressing plate and the base of the edge-locking machine, the brims of hats with different thicknesses work together, which is not convenient to use;

[0004] 2. When the hat is edge-locked, during the operation, the operator directly sets the hat edge on the edge-locking machine and turns the hat to perform the edge-locking operation. During the edge-locking operation of the hat, more manual operations are required, which can easily cause uneven edge locking. Utility Model Content

[0005] The utility model aims to provide a cap edge locking machine for hat production. By arranging a cap edge locking machine body, a driving motor, a fixing cylinder and an electric push rod, the utility model solves the problems that the cap edge locking machine is not suitable for hats of different thicknesses and the cap edge locking work requires more manual operations.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a cap edge locking machine, comprising an edge locking machine body, a driving motor, a fixing cylinder and an electric push rod, wherein a fixing column is fixed at the bottom of the head of the edge locking machine body, a threaded rod is threadedly connected to the bottom end of the fixing column, a hexagonal rotating block is fixed to the circumference of the threaded rod below the fixing column, a pressing plate is rotatably connected to the bottom end of the hexagonal rotating block, a base is arranged below the pressing plate, the base is fixed to the edge locking machine body, a driving motor is arranged on one side of the base, a rotating disk is fixed to the output end of the driving motor, a fixing cylinder is fixed to the top center of the rotating disk A lifting column is movably connected in the fixed cylinder, an electric push rod is arranged above the fixed cylinder, the telescopic end of the electric push rod is rotatably connected with a rotating block, and a pressing frame is fixed on the circumferential side of the rotating block. When working, the brim of the hat passing under the pressing plate is locked by the main body of the locking machine, and the turntable is driven to rotate by the driving motor to drive the fixed cylinder to rotate, and the lifting column is movably connected therein through the fixed cylinder. When the electric push rod drives the rotating block to descend, it drives the pressing block to press onto the top of the hat, restricting the top of the hat, and restricting the brim of the hat through the cooperation of the pressing frame.

[0008] Furthermore, a fixing plate is fixed to the lower part of the peripheral side of the fixing column, and lifting rods are inserted through the two corners of the fixing plate away from the fixing column. The bottom ends of the two lifting rods are fixed to the top of the pressure plate. When the fixing column is working, the lifting rods are movably connected through the fixing plate, and the lifting rods cooperate with the pressure plate to prevent the pressure plate from rotating with the rotation of the hexagonal rotating block when the pressure plate is raised or lowered.

[0009] Furthermore, a fixing frame is fixed on the peripheral side of the driving motor, and the fixing frame is fixed to a side of the base close to the driving motor, and the driving motor is fixed to the base through the fixing frame.

[0010] Furthermore, a support plate is fixed to the top of the lifting column, a compression spring 1 is fixed to the bottom of the lifting column, the bottom end of the compression spring 1 is fixed to the top of the turntable, and the lifting column cooperates with the support plate to support the inner top of the hat.

[0011] Furthermore, a connecting plate is fixed to one side of the electric push rod, the connecting plate is fixed to the top of the overlocking machine body, and the electric push rod is fixed to the overlocking machine body through the connecting plate.

[0012] Furthermore, a second compression spring is fixed to the bottom end of the rotating block, and a pressure block is fixed to the bottom end of the second compression spring. The pressure block corresponds to the position of the supporting plate, so that the center position of the hat is restricted during operation.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the edge locking machine is not suitable for hats of different thicknesses when edge locking is performed by arranging an edge locking machine body and a driving motor. When trimming the brims of hats of different thicknesses, the thickness of the brim of the hat is first determined, and the thickness of the edge of the hat is determined when edge locking is performed. Then the hexagonal rotating block is rotated to drive the threaded rod to rotate. When the threaded rod rotates, the height between the pressing plate and the base is adjusted until the brim of the hat is restricted between the pressing plate and the base in a suitable edge locking state, so that the edge locking machine is more suitable for hats of different thicknesses when edge locking is performed.

[0015] 2. The utility model solves the problem that the edge locking machine needs more manual operation to lock the edge of the hat by arranging the edge locking machine body, the driving motor, the fixing cylinder and the electric push rod. The brim of the hat body is set between the pressing plate and the base, and the inner top of the hat is adjusted to be set at the top of the supporting plate. Then the electric push rod is started, and the electric push rod drives the rotating block to descend, driving the pressing block to descend to contact the top center of the hat. At the same time, the electric push rod drives the pressing block to continue to descend. At this time, with the cooperation of the first and second compression springs, the top center of the hat is set between the supporting plate and the pressing block, until the bottom of the pressing frame is pressed onto the brim of the hat, and the hat is pressed tightly on the top of the rotating disk. With the starting of the driving motor, the disk is driven to rotate, and the pressing frame and the brim of the hat rotate together. Under the operation of the edge locking machine body, the brim of the hat is locked. During the edge locking operation, manual operation only requires putting on and taking off the hat, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The threaded rod 102 is connected through the fixing column 101. The bottom end of the fixing column 101 is threadedly connected with the threaded rod 102. A hexagonal rotating block 103 is fixed to the circumference of the threaded rod 102 below the fixing column 101. The bottom end of the hexagonal rotating block 103 is rotatably connected with a pressing plate 104. By rotating the hexagonal rotating block 103, the threaded rod 102 is driven to rotate, so that the height of the pressing plate 104 above the base 107 changes, so as to cooperate with the cap edge locking operation of different thicknesses. A base 107 is arranged below the pressing plate 104. The base 107 is fixed to the cap edge locking machine body 1, and the base 107 cooperates with the support of the cap edge. The base 107 has a driving motor 2 on one side, which drives the turntable 201 to rotate. The output end of the driving motor 2 is fixed with the turntable 201, and the fixed cylinder 3 is supported on it by the turntable 201. The fixed cylinder 3 is fixed at the top center of the turntable 201, and a lifting column 302 is movably connected in the fixed cylinder 3.

[0027] Specifically, a fixing plate 105 is fixed to the lower part of the side of the fixing column 101, and lifting rods 106 are inserted through the two corners of the fixing plate 105 away from the fixing column 101. The bottom ends of the two lifting rods 106 are fixed to the top of the pressing plate 104. The fixing column 101 is movably connected to the lifting rods 106 through the fixing plate 105, and is fixed to the pressing plate 104 through the bottom ends of the lifting rods 106, so that the pressing plate 104 will not rotate with the rotation of the threaded rod 102 when the height is adjusted.

[0028] Furthermore, a fixing bracket 202 is fixed to the peripheral side of the driving motor 2 . The fixing bracket 202 is fixed to a side of the base 107 close to the driving motor 2 . The driving motor 2 is fixed to the base 107 through the fixing bracket 202 .

[0029] The operation process of this embodiment is as follows: when working, when facing the trimming of hat brims of different thicknesses, first determine the thickness of the hat brim, and determine the thickness of the hat edge when locking the edge, then rotate the hexagonal rotating block 103 to drive the threaded rod 102 to rotate, and adjust the height between the pressing plate 104 and the base 107 when the threaded rod 102 rotates until the hat brim is restricted between the pressing plate 104 and the base 107 and is in a suitable locking state. Specific embodiment 2

[0031] See also Figure 1-5 On the basis of the specific embodiment 1, a support plate 303 is fixed to the top of the lifting column 302, and a compression spring 301 is fixed to the bottom of the lifting column 302. The bottom end of the compression spring 301 is fixed to the top of the turntable 201. When the lifting column 302 is working, the support plate 303 supports the center of the top inside the hat, and the compression spring 301 cooperates to support the lifting column 302 on the turntable 201.

[0032] Specifically, a connecting plate 405 is fixed to one side of the electric push rod 4 , and the connecting plate 405 is fixed to the top of the overlocking machine body 1 . When the electric push rod 4 is working, it is fixed to the overlocking machine body 1 through the connecting plate 405 .

[0033] Furthermore, a compression spring 402 is fixed to the bottom end of the rotating block 401, and a pressure block 403 is fixed to the bottom end of the compression spring 402. The pressure block 403 corresponds to the position of the support plate 303. When the rotating block 401 is working, the pressure block 403 is connected through the compression spring 402, and the bottom end of the pressure block 403 is pressed to the top of the hat, and with the cooperation of the compression spring 402, the pressing frame 404 presses the brim of the hat onto the turntable 201 to restrict the brim of the hat.

[0034] The operation process of this embodiment is as follows: during operation, after the position adjustment of the pressing plate 104 on the main body 1 of the edge locking machine is completed, the brim of the hat body can be set between the pressing plate 104 and the base 107, and then the top of the hat can be adjusted to be set at the top of the support plate 303, and then the electric push rod 4 is started, and the electric push rod 4 drives the rotating block 401 to descend, driving the pressing block 403 to descend to contact the top center of the hat, and at the same time, the electric push rod 4 drives the pressing block 403 to continue to descend. At this time, with the cooperation of the compression spring 1 301 and the compression spring 2 402, the top center of the hat is set between the support plate 303 and the pressing block 403, until the bottom of the pressing frame 404 is pressed onto the brim of the hat, and the hat is pressed tightly against the top of the rotating disk 201. As the driving motor 2 is started, the disk is driven to rotate, and the pressing frame 404 and the brim rotate together. Under the operation of the edge locking machine main body 1, the brim of the hat is locked.
