Description

Technical Field

[0001] The invention belongs to the technical field of machinery and relates to a cloth button wrapping machine. Background Art

[0002] A cloth-covered button is a type of button that has a cloth cover on the outside. It consists of an upper cover, a lower cover, and cloth. The cloth covers the end surface of the upper cover, and the lower cover presses the edge of the cloth against the back of the upper cover. During production, the lower cover is riveted to the back of the upper cover by stamping.

[0003] At present, cloth-wrapped buttons are generally produced in an automatic or semi-automatic manner. For example, a button-wrapping machine disclosed in a Chinese patent document [application number 201711077017.7] includes a workbench, an upper cover feeding device, a punching device, a blanking device, a lower cover feeding device, a forming mold arranged below the punching device, and a control device arranged on one side of the workbench; the forming mold includes: a telescopic device fixed on the workbench and a sliding workbench connected to the telescopic device, the sliding workbench is provided with a forming mold, and the telescopic device can drive the sliding workbench to switch between multiple stations; the forming mold includes a first forming mold and a second forming mold. The forming of the cloth-wrapped button is achieved by the cooperation of the punching device with the first forming mold and the second forming mold respectively, and the blanking device is used to blow off the cloth-wrapped button located on the first forming mold to achieve blanking.

[0004] Although the above patent can realize the automatic forming of cloth-wrapped buttons, the sliding workbench moves back and forth in a straight line, and needs to be used in conjunction with a telescopic device and a horizontal track, and the structure is relatively complex; the displacement of the sliding workbench for one back and forth movement is large, that is, the time required for a cloth-wrapped button forming process is long, resulting in low production efficiency of single-machine cloth-wrapped buttons; at the same time, in order to meet the movement of the sliding workbench, a large space must be reserved on the left and right spaces of the workbench for the back and forth movement of the sliding workbench, resulting in a large space occupied by the whole machine. The production of buttons is an intensive industry, and a larger whole machine occupies a larger area of ​​the factory, resulting in low production efficiency per unit area of ​​the factory, resulting in increased costs; when the stamping device cooperates with the second forming mold, the outer cover and the cloth need to be embedded in the sleeve first, which requires the sleeve and the punch to remain fixed during this process. This is achieved by a third cylinder and a C-shaped cam in this patent, and the structure is complex. At the same time, a control system is required to control the operation of the third cylinder, which is prone to mechanical failure or control program failure. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and propose a cloth-wrapped button machine. The technical problem solved by the present invention is to simplify the structure of the cloth-wrapped button machine and reduce its volume on the basis of realizing the forming of the cloth-wrapped button.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A cloth button wrapping machine comprises a frame and a workbench installed on the frame, wherein a stamping die that can move up and down is provided on the frame above the workbench, and a button-up die, a button-drop die and a button-pressing die are provided on the workbench. It is characterized in that a driving member is installed on the frame, and the driving end of the driving member is connected to the workbench and drives the workbench to swing back and forth, and the button-up die, the button-drop die and the button-pressing die can all be moved to directly below the stamping die through the swing of the workbench.

[0008] In actual production, an upper cover and fabric are placed in the button die, and a lower cover is placed in the press die. The driving member drives the workbench to swing, so that the button die, the press die and the drop die are moved to the bottom of the stamping die in sequence. The stamping die cooperates with the button die, the press die and the drop die in sequence to realize the forming of the cloth-wrapped button. The swing of the workbench only requires the driving end of the driving member to be directly connected to the workbench without going through a transmission mechanism. At the same time, the forming process of the cloth-wrapped button can be realized by swinging. While solving the purpose of forming the cloth-wrapped button, the structure of the whole machine is simpler and the cost is lower. At the same time, since the swing of the workbench requires less space on the left and right sides, the whole machine will be more compact, reducing the site occupation, and more cloth-wrapped button machines can be placed per unit area, thereby improving the utilization rate of the factory building and directly reducing the production cost.

[0009] In the above-mentioned cloth button machine, the button drop mold is located between the button up mold and the button press mold. The initial position of the punching mold is aligned with the button drop mold. At this time, the tops of the button up mold and the button press mold are open, which can facilitate workers to place the upper cover and fabric on the button up mold and the lower cover on the button press mold.

[0010] In the above-mentioned cloth button machine, the arc size between the button-up mold and the pressing mold is π / 3 to 2π / 3. This structure can not only meet the requirements of placing the button-up mold, the button-drop mold and the pressing mold on the workbench to avoid interference, but also enable the workbench to swing at a small angle to move one of the three button-up mold, the button-drop mold and the pressing mold to the bottom of the stamping mold, so as to achieve fast and accurate switching of the workstations, reduce the time required for forming a cloth button, and thus improve production efficiency.

[0011] In the above-mentioned cloth button machine, the driving member is a motor, the motor is fixed below the base, the motor shaft of the motor passes through the base, one side of the workbench has a connecting hole, the motor shaft of the motor passes through the connecting hole and is fixed to the workbench. The motor shaft of the motor is directly connected to the workbench without passing through a transmission structure, which greatly simplifies the structure, reduces production costs, and at the same time makes the structure more compact and reduces the volume of the whole machine.

[0012] As another case, in the above-mentioned cloth button machine, the driving member is a rotary cylinder, the rotary cylinder is fixed below the base, the rotary shaft of the rotary cylinder passes through the base, one side of the workbench has a connecting hole, the rotary shaft of the rotary cylinder passes through the connecting hole and is fixed to the workbench. The rotary shaft of the rotary cylinder is directly connected to the workbench without passing through a transmission structure, which greatly simplifies the structure and reduces the production cost. At the same time, the structure is more compact and the volume of the whole machine is reduced.

[0013] In the above-mentioned cloth button machine, a base is provided on the frame directly below the stamping die, and the workbench is located on the base and abuts against the base. The base can keep the workbench swinging horizontally, and at the same time, the base provides support for the workbench when the stamping die is stamping with one of the three, the buckle-on die, the buckle-off die and the buckle-pressing die, and the structure is simple.

[0014] In the above-mentioned cloth button machine, the width of the base is smaller than the width of the workbench. This structure can reduce the contact area between the base and the workbench, thereby reducing the friction resistance when the two move relative to each other, making the swing of the workbench smoother and reducing noise.

[0015] In the above-mentioned cloth button wrapping machine, the stamping die includes a punch that can move up and down and a stamping sleeve sleeved on the punch, and a spring 1 is provided between the stamping sleeve and the punch to keep the stamping sleeve at the lower end of the punch; the buckle die includes a buckle top column and a buckle sleeve sleeved on the buckle top column, and the buckle top column is vertically fixed on the workbench, and the buckle sleeve can move up and down relative to the buckle top column, and a spring 2 is provided between the buckle sleeve and the buckle top column to keep the buckle sleeve at the upper end of the buckle top column, and the workbench is provided with a positioning mechanism that can keep the stamping sleeve at the lower end of the punch when the buckle die moves to just below the stamping die. When making up, first place the upper cover and the cloth in the make-up mold, wherein the upper cover is sleeved on the top of the upper make-up, and the cloth is placed above the upper cover, and the cloth is located on the inner side of the make-up sleeve. The diameter of the make-up sleeve matches the cloth, and the cloth can be quickly positioned. After the discharge is completed, the workbench drives the make-up mold to move to just below the stamping mold. At the same time, the positioning structure acts on the make-up mold to keep the stamping sleeve at the lower end position of the punch. Then the punch moves downward with the stamping sleeve, and the stamping sleeve presses downward against the make-up sleeve and makes the make-up sleeve move downward relative to the make-up top column. The make-up top column pushes the upper cover and the cloth into the stamping sleeve. After the punch is reset, the upper cover and the cloth are stuck in the stamping sleeve, completing the step of the upper cover and the cloth being stuck in the stamping sleeve. At the same time, the make-up sleeve is reset by spring 2. After the workbench is transferred to the next station, the positioning mechanism is separated from the stamping mold.

[0016] In the above-mentioned cloth button wrapping machine, the positioning mechanism includes a guide column vertically fixed on the workbench and a positioning block sleeved on the guide column, the guide column and the button die are located on the same side of the workbench, the punch is fixed with a limiting plate near the upper end, the limiting plate is spaced apart from the stamping sleeve located at the lower end of the punch, the thickness of the positioning block is equivalent to the spacing between the limiting plate and the stamping sleeve located at the lower end of the punch, the positioning block can move up and down relative to the guide column, and when the button die moves to directly below the stamping die, the positioning block is inserted between the limiting plate and the stamping sleeve.

[0017] When making up, the positioning block is inserted between the limit plate and the stamping sleeve. When the punch moves downward, the positioning block moves downward accordingly. When the stamping sleeve and the make-up sleeve are against each other, the stamping sleeve and the punch always remain relatively fixed, thereby ensuring that the upper cover and the cloth are pressed into the stamping sleeve to realize the make-up process.

[0018] In the above-mentioned cloth buckle machine, the buckle mold includes a buckle top column and a buckle template sleeved on the buckle top column, the buckle top column is vertically fixed on the workbench, and a spring four is provided between the buckle template and the buckle top column to keep the buckle sleeve on the upper end of the buckle top column, the elastic force of the spring four is greater than the elastic force of the spring two, and the upper edge of the inner hole of the buckle template is provided with a ring-shaped pressing chamfer, and the upper edge of the buckle top column has a flange chamfer. When pressing the buckle, the lower cover is placed on the upper end of the pressing buckle top column, the punch moves downward, and the stamping sleeve rests on the pressing buckle template. Since the elastic force of spring four is greater than the elastic force of spring two, the punch will move downward relative to the stamping sleeve to push the upper cover and the cloth in the stamping sleeve downward, and the edge of the cloth is folded toward the inner side of the back of the upper cover under the guidance of the pressing edge chamfer. At the same time, the edge of the upper cover is also bent inward under the action of the pressing edge chamfer. At this time, the punch and the stamping sleeve move downward synchronously, the spring four is compressed, and the pressing buckle template moves downward, and the pressing buckle top column pushes the lower cover into the inner side of the upper cover, and the lower cover presses the cloth folded into the inner side of the back of the upper cover into the upper cover, and at the same time, the inwardly bent edge of the upper cover will rest against the flange chamfer, and under the action of the flange chamfer, the bent edge is further folded inward, so that the lower cover is riveted and fixed to the inner side of the upper cover, completing the forming of the cloth-wrapped buckle, and the formed cloth-wrapped buckle is located in the stamping sleeve.

[0019] Compared with the prior art, the cloth button wrapping machine has the advantages of simple structure, higher forming efficiency of the cloth button wrapping, and smaller volume of the whole machine. BRIEF DESCRIPTION OF THE DRAWINGS
