Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, the present application proposes an automatic quick die change device for seam clamps of underwear underpants, comprising: the template is embedded in the template frame, and the template is magnetically attracted with the template frame. As shown in fig. 2, in an example, the template frame includes an upper template frame 110 and a lower template frame 120, and one end of the upper template frame 110 is rotatably connected to the lower template frame 120. The die plates include an upper die plate 130 and a lower die plate 140.

It should be noted that the template is embedded in the template frame, and a slot for placing the template should be provided in the template frame. The depth of the groove of the template frame is at least consistent with the thickness of the template, namely, after the template is embedded in the groove of the template frame, the template does not protrude out of the template frame, and the template can be slightly lower than the template frame. In a preferred embodiment of the present application, the depth of the groove of the template frame is the same as the thickness of the template, i.e. after the template is embedded in the groove of the template frame, the template and the template frame are in the same plane.

In this embodiment, the depth of the groove of the template frame is set to be the same as the thickness of the template, but a small height error may exist without affecting the automatic seam allowance sewing jig 100.

It should be noted that the form and the form frame may be configured to be a transition fit or a clearance fit. In actual production, in order to facilitate the assembly and disassembly of the formwork, the formwork and the formwork frame are usually in clearance fit.

It should be noted that the magnetic attachment means that the positions of the template and the template frame are relatively fixed by magnetic force, specifically, one of the template or the template frame may be provided with a magnet 150, and the other of the template or the template frame may be provided with a magnetic material, so that the magnetic force of the magnet 150 on the magnetic material is utilized to fix the positions of the template and the template frame; the opposite-polarity magnet 150 may be provided in the template or the template frame, and the position of the template and the template frame may be fixed by the principle of opposite-polarity attraction.

In this embodiment, the position fixing of the template and the template frame is performed in such a manner that one of the template and the template frame is provided with the magnet 150 and the other of the template and the template frame is provided with the magnetic material. Specifically, the magnetic 150 may be disposed on the template, the template frame may be disposed as a magnetic material, and the magnetic force of the magnetic 150 is utilized to magnetically attract the template frame, so that the positions of the template and the template frame are fixed; the magnetic force of the magnet 150 may be used to magnetically attract the template, thereby fixing the position of the template and the template frame.

Through making template and template frame adopt magnetism to inhale in above-mentioned scheme and connect, only need be close to template and template frame when the installation, utilize magnetic force between magnet 150 and the magnetic material to make template and template frame relatively fixed, only need when dismantling separate template and template frame make magnetic force between them reduce can, for the threaded connection who adopts among the prior art, operating procedure and the operation degree of difficulty when installation and dismantlement all have great improvement, use the demand of the quick transfer in market more, also can be in actual production save time, thereby the time cost is saved, and the production efficiency is improved.

Referring to fig. 2 and 3, further, the template frame includes an upper template frame 110 and a lower template frame 120, and one end of the upper template frame 110 is rotatably connected to the lower template frame 120.

It should be noted that, in the automatic seam allowance slit, the clothes to be processed are sandwiched between the upper template 130 and the lower template 140, and the processed clothes are taken out and put in the clothes to be processed again after the clothes processing is completed. This requires that the upper and

lower templates

130, 140 be opened frequently during use of the automatic shirttail flat seam clamp 100. Since the upper mold plate 130 and the lower mold plate are embedded in the upper mold plate frame 110 and the lower mold plate frame 120, respectively, the upper mold plate frame 110 and the lower mold plate frame 120 are rotatably connected.

In this embodiment, the upper plate frame 110 and the lower plate frame 120 are connected by a hinge, and the upper plate frame 110 can rotate around the hinge relative to the lower plate frame 120 by using the structure of the hinge itself, so as to open and close the upper plate frame 110 and the lower plate frame 120, thereby facilitating the taking out of the processed clothes and the putting in of the clothes to be processed.

Further, the mold plates include an upper mold plate 130 and a lower mold plate 140, and the upper mold plate 130 and the lower mold plate 140 are respectively embedded in the upper mold plate frame 110 and the lower mold plate frame 120. That is, the upper plate 130 is embedded in the upper plate frame 110, and the lower plate 140 is embedded in the lower plate frame 120.

Specifically, the upper plate frame 110 should be provided with a groove for embedding the upper plate 130, the groove having a thickness substantially equal to that of the upper plate 130, the groove being in clearance fit with the upper plate 130. Similarly, the lower plate frame 120 should be provided with a slot for receiving the lower plate 140, the slot having a thickness substantially equal to the thickness of the lower plate 140, the slot having a clearance fit with the lower plate 140.

Referring to fig. 3, further, the upper plate frame 110 includes: a lower plate 112, a through groove 113 is opened on the lower plate 112, and the upper plate 130 is accommodated in the through groove 113.

It should be noted that, when the upper plate 130 is accommodated in the through groove 113, the size of the through groove 113 needs to be larger than that of the upper plate 130, and the through groove 113 and the upper plate 130 are in clearance fit.

Upper plate frame 110 further includes an upper plate 111, and upper plate 111 is removably attached to a lower plate 112. Specifically, the upper plate 111 and the lower plate 112 may be detachably connected using a screw structure, a snap structure, a wedge structure, or the like. In this embodiment, the upper plate 111 and the lower plate 112 are screwed with screws.

The upper plate 111 is provided with a dismounting groove 114, and the dismounting groove 114 penetrates through the upper plate 111 and is mainly used for dismounting the upper template 130. When it is desired to remove upper plate 130, upper plate 130 can be detached from upper plate frame 110 by pushing upper plate 130 through removal slot 114 from the end of upper plate 111 distal to lower plate 112 using an object.

The upper plate 111 has a plurality of magnets 150 embedded therein along the edge of the mounting and dismounting groove 114. Preferably, a plurality of magnets 150 are embedded in the upper plate 111 along the circumference of the detachable groove 114.

The magnet 150 refers to a substance or material capable of generating a magnetic field. In the present application, the magnet 150 may be a permanent magnet 150 such as a magnet that can maintain magnetism for a long period of time, or may be a soft magnet 150 such as an electromagnet that generates magnetism by manual intervention.

In this embodiment, the upper plate 111 is provided with a plurality of grooves for receiving the magnets 150, which are provided at the side where the upper plate 111 and the lower plate 112 are coupled, and are provided around the detachable groove 114. The magnets 150 and slots may be a clearance fit or a transition fit. In this embodiment, the magnet 150 and the slot are in transition fit to reduce damage to the magnet 150 or the upper plate 111 caused by movement of the magnet 150 in the slot. In addition, the magnet 150 is exposed to the opening range of the through groove 113 so that the magnet 150 can directly face the template, and the attractive force when magnetically attached to the template is better.

It should be noted that the magnet 150 and the upper plate 111 may be connected by magnetic attraction, adhesion, or the like, and in this embodiment, the magnet 150 is adhered in the groove of the upper plate 111.

In order to stably connect the magnet 150 and the upper plate 111, in the present embodiment, the upper plate 111 is made of a magnetic material, so that when the magnet 150 is embedded in the upper plate 111, the magnet 150 is more firmly mounted by using the magnetic force between the magnet 150 and the upper plate 111.

It should be noted that, for the connection between the magnet 150 and the upper plate 130, the size of the dismounting groove 114 needs to be set smaller than that of the upper plate 130. Only when the size of the disassembly and assembly groove 114 is smaller than that of the upper mold plate 130, the magnets 150 disposed around the disassembly and assembly groove 114 will partially or entirely act on the upper mold plate 130.

In the present embodiment, the magnet 150 is partially exposed in the opening range of the through slot 113, and the rest is located between the upper plate 111 and the lower plate 112, and since the upper plate 111 and the lower plate 112 are screwed by screws, the magnet 150 can be fixed by the lower plate 112, and the magnet 150 is prevented from being taken out of the upper plate 111 when the upper mold plate 130 is disassembled.

After the template is embedded in the groove of the template frame, the template and the template frame should be in the same plane, which can be realized in the following three ways in theory: when the thickness of the upper mold plate 130 is smaller than that of the lower mold plate 112, the through groove 113 of the lower mold plate 112 may be provided as a stepped groove, the stepped through groove 113 is provided at an end far from the upper plate 111 for accommodating the upper mold plate 130, and an end near the upper plate 111 is fitted to the disassembly groove 114 for disassembly of the upper mold plate 130; when the thickness of the upper mold plate 130 is smaller than that of the lower mold plate 112, the attaching and detaching groove 114 of the upper plate 111 may be provided as a stepped groove, one end of the stepped attaching and detaching groove 114 near the lower plate 112 cooperates with the penetrating groove 113 of the lower plate 112 to accommodate the upper mold plate 130, and one end of the attaching and detaching groove 114 far from the lower plate 112 is used for detaching the upper mold plate 130; when the thickness of the upper mold plate 130 is exactly equal to the thickness of the lower mold plate 112, the through-groove 113 of the lower mold plate 112 serves to receive the upper mold plate 130, and the removal groove 114 of the upper mold plate 111 serves to remove the upper mold plate 130.

In order to facilitate the processing of the parts, considering that the processing of the step groove is complicated, in this embodiment, the thickness of the lower plate 112 is the same as that of the upper plate 130, the upper plate 130 is embedded in the through groove 113, and the upper plate 130 and the lower plate 112 are in the same plane. This also has the advantage that, since the size of the removal slot 114 is smaller than that of the upper mold plate 130, the size of the removal slot 114 is necessarily smaller than that of the through slot 113, and then the magnet 150 will be partially or entirely located within the through slot 113, and the connection between the magnet 150 and the upper mold plate 130 will not be affected by the lower plate 112.

Further, the upper plate 130 is made of a magnetic material. Magnetic materials are materials that react in some way to a magnetic field. In the present application, the magnetic material may be a material that can be attracted by the magnet 150, such as iron.

In the present embodiment, the upper plate 130 is made of a stainless steel material having magnetism, such as duplex stainless steel, martensitic stainless steel, and ferritic stainless steel.

Further, the lower template frame 120 is provided with a mounting groove 121, and the lower template 140 is received in the mounting groove 121.

It should be noted that, the lower mold plate 140 is accommodated in the mounting groove 121, and then the size of the mounting groove 121 needs to be larger than that of the lower mold plate 140, and the mounting groove 121 and the lower mold plate 140 are in clearance fit.

The mounting groove 121 may or may not penetrate through the lower mold plate frame 120. When the installation groove 121 penetrates through the lower template frame 120, in order to achieve magnetic attraction connection between the lower template 140 and the lower template frame 120, the installation groove 121 should be set to be a stepped groove, one end of the stepped installation groove 121 near the upper template frame 110 is marked as upper for accommodating the lower template 140, one end of the stepped installation groove 121 far away from the upper template frame 110 is marked as lower, and the size below the installation groove 121 should be smaller than that above the installation groove 121, so that after the lower template 140 is installed above the stepped installation groove 121, there is the lower template frame 120 in contact with the lower surface of the lower template 140. When the installation groove 121 does not penetrate the lower mold plate frame 120, the installation groove 121 is used to receive the lower mold plate frame 120.

In the present embodiment, in order to reduce the production cost of the low mold plate frame 120, a through mounting groove 121, i.e., a stepped mounting groove 121, is employed. Since the upper portion of the mounting groove 121 is used for accommodating the lower template 140, the depth of the upper portion of the mounting groove 121 is adapted to the thickness of the lower template 140, so that the lower template 140 is not protruded out of the lower template frame 120 after being inserted into the mounting groove 121, and the lower template 140 and the lower template frame 120 are located on the same horizontal plane.

Referring to fig. 5, further, a plurality of magnets 150 are embedded in the lower plate 140.

In this embodiment, magnets 150 are embedded in the lower platen 140 on the side of the distal upper platen 130. The side of lower platen 140 distal to upper platen 130 may be slotted with a plurality of slots for receiving magnets 150. The magnets 150 and slots may be a clearance fit or a transition fit. In this embodiment, the magnets 150 and the slots are in transition fit to reduce damage to the magnets 150 or the lower template frame 120 caused by movement of the magnets 150 in the slots.

Meanwhile, the magnets 150 may be distributed at the peripheral edges of the lower mold plate 140, and the size of the lower portion of the mounting groove 121 may be as large as possible on the premise of ensuring that the magnets 150 can contact and be stably connected with the lower mold plate frame 120, so as to achieve the purpose of reducing the cost of the lower mold plate frame 120.

In order to stably connect the magnet 150 and the lower mold plate 140, in the present embodiment, the lower mold plate 140 is made of a magnetic material, so that when the magnet 150 is embedded in the lower mold plate 140, the magnet 150 is more firmly mounted by using the magnetic force between the magnet 150 and the lower mold plate 140.

Further, the lower template frame 120 is made of a magnetic material.

Referring to fig. 4, further, the mounting groove 121 is provided with a curved groove 122, and the curved groove 122 is used for detaching the lower template 140.

It should be noted that when the automatic seam allowance slit clamp 100 is used, the lower template frame 120 is usually fixed on an operation table, so that the template is prevented from moving during the seam allowance slit process to influence the seam allowance slit quality and efficiency. Since the lower mold plate 140 is embedded in the mounting groove 121, there may be difficulty in disassembling the lower mold plate 140 since the lower mold plate 140 does not protrude from the lower mold plate frame 120.

And the curved groove 122 arranged in the mounting groove 121 is arranged at the boundary between the side wall of the mounting groove 121 and the side surface of the lower template frame 120 close to the upper template 130, and the curved groove 122 can be used as a prying point when the lower template 140 is disassembled. When the lower template 140 needs to be disassembled, other tools can be used, the curved groove 122 serves as a prying point for supporting, one end of the lower template 140 is pried, and then the lower template 140 is disassembled.

Further, the upper mold plate frame 110 is connected with a driving member 160 for driving the upper mold plate frame 110 to rotate relative to the lower mold plate frame 120.

Since the upper and

lower templates

130 and 140 are frequently opened when the automatic shirt slit clamp 100 is in use, and the lower template frame 120 is generally fixed to an operating table, opening the upper and

lower templates

130 and 140 requires rotation of the upper template frame 110 relative to the lower template frame 120. In order to reduce the labor of the operator and increase the automation degree of the apparatus, the upper plate frame 110 is connected to a driving unit 160, and the driving unit 160 can drive the upper plate frame 110 to rotate relative to the lower plate frame 120, so as to open or close the upper plate 130 and the lower plate 140.

It should be noted that the driving member 160 may be provided as a motor, a cylinder, or the like. In this embodiment, the driving member 160 is configured as a telescopic cylinder, and the two ends of the telescopic cylinder are respectively hinged to a fixed point and the upper mold plate frame 110, so that the upper mold plate frame 110 is controlled to rotate relative to the lower mold plate frame 120 by the telescopic cylinder. Specifically, when the telescopic cylinder is extended, the upper mold frame 110 is closed with respect to the lower mold frame 120, and when the telescopic cylinder is shortened, the upper mold frame 110 is opened with respect to the lower mold frame 120.

When the automatic shirt vent flat seam clamp 100 needs to change a mold, the upper plate frame 110 is driven to rotate relative to the lower plate frame 120 through the driving piece 160, the upper plate frame 110 and the lower plate frame 120 are opened, an object penetrates through the dismounting groove 114 from one end, far away from the lower plate 112, of the upper plate 111 to push the upper plate 130 out, the upper plate 130 can be separated from the upper plate frame 110, the curved surface groove 122 is used as a prying point to support through other tools, one end of the lower plate 140 is pried, dismounting of the lower plate 140 is further achieved, then the other set of lower plate 140 is placed into the mounting groove 121 of the lower plate frame 120, the magnet 150 embedded in the lower plate 140 and the lower plate frame 120 made of magnetic materials generate magnetic attraction and fixation, the upper plate 130 is placed into the penetrating groove 113 of the lower plate 112, and the magnet 150 embedded in the upper plate 111 and the upper plate 130 made of magnetic materials generate magnetic attraction and fixation, and installation can be completed.

Compared with the prior art that the upper template 130 and the lower template 140 are respectively connected with the upper template frame 110 and the lower template frame 120 through threads, the installation and disassembly steps are reduced, the operation steps and the operation difficulty during installation and disassembly are greatly improved, the method is more suitable for the requirement of rapid change in the market, and can also save time in actual production, thereby saving time cost and improving production efficiency.
