Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to a quick-change mold clamp. Background Art

[0002] Traditional special industrial sewing machines require a dedicated person to operate the sewing equipment with "eyes, hands and feet" to achieve sewing needs. Of course, there are also some automatic sewing machines at present. Such automatic sewing machines require professional CNC personnel to operate and set the program to achieve automatic sewing. Moreover, these automatic sewing machines require corresponding processing graphics boards (molds) during processing to allow the sewing mechanism to sew according to the contour of the processing graphics board. However, the current automatic sewing machines usually use manual pressing to process the graphics board or directly integrate it into the sewing mechanism, which cannot be easily replaced. The manual pressing method is prone to errors and it is difficult to control the pressing force, resulting in fabric deviation.

[0003] Therefore, a clamping jaw capable of quickly changing molds is urgently needed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this application is to provide a quick mold change clamp to address the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above application purpose, the present application adopts the following technical solution: a quick mold change clamp for quickly disassembling and assembling the mold, comprising:

[0006] A pressing plate, arranged above the die, for squeezing the die;

[0007] A connecting block is arranged on the top of the pressing plate and connected to the bottom output end of the elastic seat;

[0008] An elastic seat, with a connecting rod on the top and a connecting block on the bottom;

[0009] An elastic reset member is arranged between the connecting block and the elastic seat;

[0010] The positioning mechanism is arranged at both ends of the pressing plate and is used to actively fix or release the mold.

[0011] Working principle and beneficial effects: 1. Compared with the prior art, this application can quickly move the clamp to the specified position by installing the connecting rod on other devices, such as multi-axis drive structure, XYZ three-axis drive and other drive devices. The elastic seat and elastic reset member not only play a buffering role, but also prevent the fabric from being unable to move due to excessive pressure.

[0012] 2. Compared with the prior art, the positioning mechanism of the present application can realize rapid replacement of the mold by actively fixing or releasing the mold.

[0013] Furthermore, the positioning mechanism includes a vacuum suction component, and the mold is provided with a vertical portion corresponding to the vacuum suction component. In this way, the mold can be quickly disassembled and assembled by using the vacuum suction component to suck the vertical portion of the mold, and the difficulty of implementation is low.

[0014] Furthermore, the positioning mechanism includes a positioning end and a horizontal driver for driving the positioning shaft in the positioning end to extend and retract, and a positioning hole that cooperates with the positioning shaft is provided on the mold. In this way, the horizontal driver is used to drive the positioning shaft to extend and retract, and the positioning hole can be used to quickly realize the disassembly and assembly of the mold, which is easy to realize and has higher positioning accuracy than the vacuum suction component.

[0015] Furthermore, the positioning mechanism includes an electromagnetic component, and the mold is provided with a magnetizing part that cooperates with the electromagnetic component. In this way, the mold can be quickly disassembled and assembled by utilizing the characteristics that the magnet can attract magnetic metals such as stainless steel and the electromagnetic component has magnetism when it is powered on and disappears when it is not powered on.

[0016] Furthermore, the horizontal driver is an electromagnet, and a positioning shaft and a spring are arranged inside the electromagnet. The positioning shaft is sucked into the electromagnet when the electromagnet is powered on, and is ejected out of the electromagnet by the spring when the electromagnet is powered off. In this way, compared with the electromagnetic assembly, it is more energy-saving. When the mold is fixed, the electromagnet does not need to be powered on, and the clamping force is provided by the spring. When the mold needs to be removed, the electromagnet is powered on, which can greatly save electricity and is more environmentally friendly.

[0017] Furthermore, the horizontal drive is a pneumatic cylinder or an electric cylinder. In this way, both the electric cylinder and the pneumatic cylinder can be executed quickly and accurately, and can be selected according to needs. Compared with the electromagnet, the pneumatic cylinder or the electric cylinder has a larger stroke, so it can be applied to more large and small molds and has a wider range of applications.

[0018] Furthermore, the magnetizing part is provided with a groove which matches the protruding part of the electromagnetic component, and a stainless steel layer is provided in the groove. In this way, the electromagnetic component can be quickly inserted into the groove to absorb the stainless steel layer after being powered on, so as to achieve precise positioning.

[0019] Furthermore, the elastic reset element is a spring, which has a simple structure and low cost.

[0020] Furthermore, the positioning mechanism is arranged at both ends of the pressing plate in the length direction, so as to achieve better stability.

[0021] Furthermore, the pressure plate is located at the center of the mold, which further improves stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 As shown, this quick mold change clamp is used for quick disassembly and assembly of molds, including:

[0028] A pressing plate 1 is disposed above the die 2 and is used for extruding the die 2;

[0029] In this embodiment, the function of the pressing plate 1 is to connect the mold 2 and transmit pressure. The mold 2 is used as a processing pattern board during sewing. When the sewing equipment is sewing, it is necessary to sew along the contour of the mold 2, so the rapid disassembly and assembly of the mold 2 is very important. Preferably, a positioning hole 21 can be added to the mold 2, and the positioning is achieved by inserting the jack at the bottom of the pressing plate 1 into the positioning hole 21, that is, the pressing plate 1 is required to be located at the center of the mold 2.

[0030] The connecting block 3 is arranged on the top of the pressing plate 1 and connected to the bottom output end of the elastic seat 4;

[0031] In this embodiment, the function of the connecting block 3 is to connect the pressure block, which is installed at the output end of the elastic seat 4. The connecting block 3 and the pressure plate 1 are connected by threaded fasteners such as bolts, and the output end of the connecting block 3 and the elastic seat 4 are connected by structures such as threads or screws.

[0032] The elastic seat 4 has a connecting rod 41 on the top and is connected to the connecting block 3 at the bottom; the connecting block 3 is mainly connected through a telescopic shaft.

[0033] In this embodiment, the elastic seat 4 cooperates with the elastic reset member 5 to prevent the fabric from being unable to move due to excessive pressure. The connecting rod 41 can be installed on other devices, such as a multi-axis drive structure, an XYZ three-axis drive and other drive devices, so that the clamp can be quickly moved to a specified position.

[0034] An elastic reset member 5 is provided between the connecting block 3 and the elastic seat 4;

[0035] In this embodiment, the elastic return member 5 is a spring, which is installed between the connecting block 3 and the elastic seat 4 and is arranged at the periphery of the output end of the elastic seat 4 .

[0036] The positioning mechanism 6 is disposed at both ends of the pressing plate 1 in the length direction and is used to actively fix or release the mold 2 .

[0037] In this embodiment, the positioning mechanism 6 can have many implementation modes, and all implementation modes are to fix or release the mold 2 through the active action of the positioning mechanism 6 .

[0038] In one embodiment, the positioning mechanism 6 may be a vacuum suction component, which uses the vacuum suction principle to suck the vertical portions 7 at both ends of the mold 2, so that the mold 2 can be quickly replaced by sucking and releasing.

[0039] In one embodiment, the positioning mechanism 6 includes an electromagnetic component, and the mold 2 is provided with a magnetizing portion that cooperates with the electromagnetic component. That is, the electromagnetic component generates a magnetic field that can attract metals such as stainless steel that can be attracted by magnets, and the mold 2 can also be quickly disassembled and assembled. Preferably, in order to allow the electromagnetic component to be quickly inserted into the groove after being energized to absorb the stainless steel layer and achieve precise positioning, the magnetizing portion is provided with a groove that cooperates with the protruding part of the electromagnetic component, and the stainless steel layer is provided in the groove.

[0040] In one embodiment, the positioning mechanism 6 includes a positioning end and a horizontal driver for driving the positioning shaft 61 in the positioning end to extend and retract. The mold 2 is provided with a positioning hole 21 that cooperates with the positioning shaft 61, and the positioning hole 21 is also provided on the vertical portion 7. That is, on this basis, it can be developed into a horizontal driver that is an electromagnet, and the electromagnet is provided with a positioning shaft 61 and a spring. The positioning shaft 61 is sucked into the electromagnet when the electromagnet is powered on, and the positioning shaft 61 is ejected out of the electromagnet by the spring when the electromagnet is powered off. In this way, it is more energy-saving than the electromagnetic component. When the mold 2 is fixed, the electromagnet does not need to be powered on, and the clamping force is provided by the spring. When the mold 2 needs to be removed, the electromagnet is powered on, which can greatly save electricity and is more environmentally friendly.

[0041] In another embodiment, the horizontal drive is a pneumatic cylinder or an electric cylinder. In this way, both the electric cylinder and the pneumatic cylinder can be executed quickly and accurately, and can be selected according to needs. Compared with the electromagnet, the pneumatic cylinder or the electric cylinder has a larger stroke, so it can be applied to molds 2 of more sizes and has a wider range of applications.

[0042] Figure 2 This is an implementation diagram of the present application applied to automatic sewing equipment.

[0043] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0044] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0045] Although the terms such as pressing plate 1, mold 2, connecting block 3, elastic seat 4, elastic reset member 5, positioning mechanism 6, vertical portion 7, positioning hole 21, connecting rod 41, positioning shaft 61 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of this application; interpreting them as any additional restrictions is contrary to the spirit of this application.
