Description

Technical Field

[0001] This invention belongs to the technical field of shoulder badge production equipment, specifically relating to a shoulder badge shaping device. Background Technology

[0002] Epaulettes are a type of apparel product. In their production, epaulettes are first processed into a flat shape, and then shaped into different curved surfaces using a shaping device to conform to the curved structure of the human shoulder. Existing epaulette cold-setting equipment uses concave and convex dies for stamping and shaping. Specifically, the heated epaulette is placed on the concave die, and then the convex die presses it downwards into the concave die. Cooling and shaping then maintains the stamped shape.

[0003] When placing the epaulettes into the groove of the die, the epaulettes are prone to lateral shift, which will affect the quality of the epaulette shaping. Summary of the Invention

[0004] This invention provides an epaulette shaping device to address the technical problem of epaulettes easily shifting laterally when placed on a lower mold.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A shoulder strap shaping device is provided, comprising:

[0007] The upper mold has an arc-shaped protrusion at the bottom;

[0008] The lower mold has an arc-shaped groove at the top that mates with an arc-shaped protrusion; the lower mold has support plates on both sides of the arc-shaped groove, wherein the support plates are hinged to the lower mold and have a rotational elastic element at the hinge position; the side wall of the arc-shaped groove has a clearance groove for accommodating the support plates.

[0009] A limiting protrusion is connected to the support plate near the hinge axis; when the support plate is horizontally positioned, the limiting protrusion is used to contact the end of the epaulette to laterally limit the epaulette.

[0010] A limiting structure is provided at the hinge position of the support plate and is connected to the lower mold; when the support plate rotates to a horizontal position under the elastic force of the rotary elastic element, the limiting structure is used to restrict the position of the support plate.

[0011] In one possible implementation, the top of the support plate is curved, and when the support plate is located within the clearance groove, the top of the support plate is coplanar with the arcuate groove.

[0012] In one possible implementation, the length of the limiting protrusion is less than the thickness of the epaulette; when the upper and lower molds cooperate to stamp the epaulette and press it into place, the limiting protrusion rotates to a horizontal position and is located in the gap between the arc-shaped protrusion and the arc-shaped groove.

[0013] In one possible implementation, the limiting protrusion is a plate-like structure, and there is a preset angle between the limiting protrusion and the support plate.

[0014] In one possible implementation, the lower mold is provided with baffles at both ends of the arc-shaped groove to longitudinally limit the shoulder strap.

[0015] In one possible implementation, the lower mold has a rotation groove at the hinge position of the support plate, and the limiting structure includes:

[0016] A first limiting plate is connected to the support plate and is located near the hinge position of the support plate;

[0017] The second limiting plate is connected to the inner wall of the rotating groove;

[0018] When the support plate is rotated to a horizontal position, the top of the second limiting plate contacts the bottom of the first limiting plate.

[0019] In one possible implementation, the second limiting plate has a groove, a limiting rod is slidably disposed in the groove, an elastic element is sleeved on the limiting rod, and the two ends of the elastic element are respectively connected to the limiting rod and the side wall of the groove;

[0020] One end of the limiting rod can slide out of the sliding groove, and the support plate has a positioning hole that is inserted and engaged with the limiting rod; when the support plate is located in the clearance groove, the positioning hole is aligned with the limiting rod, and the limiting rod is inserted and engaged with the positioning hole under the elastic force of the elastic element.

[0021] In one possible implementation, a guide ring is connected to the side of the chute away from the limiting rod, and a pull rope is provided inside the chute. One end of the pull rope is connected to the limiting rod, and the other end of the pull rope passes through the guide ring and extends to the upper surface of the lower mold.

[0022] The upper surface of the lower mold has a positioning structure that controls the position of the pull rope so that the limiting rod is separated from the positioning hole.

[0023] In one possible implementation, the positioning structure includes:

[0024] A slide rail is connected to the upper surface of the lower mold; the slide rail faces the rotating groove.

[0025] A slider is slidably mounted on the slide rail; the slider has a first insertion hole, and the lower mold has a second insertion hole for alignment with the first insertion hole.

[0026] A plug rod is disposed on the slider; the plug rod is used to engage with the first socket and the second socket.

[0027] When the insertion rod is inserted into the first insertion hole and the second insertion hole, the limiting rod separates from the positioning hole.

[0028] In one possible implementation, the lower mold is rotatably equipped with a roller near the rotating groove, and the pull rope is rotatably engaged with the roller.

[0029] This invention provides an epaulette shaping device. Compared with the prior art, the heated epaulette is placed on a support plate, and the side of the epaulette contacts the limiting protrusion, which can play a lateral limiting role for the epaulette, thereby reducing the occurrence of lateral displacement of the epaulette. By setting a rotary elastic element at the hinge position of the support plate, the support plate can be rotated to a horizontal position under the elastic force of the rotary elastic element. The limiting structure limits the support plate, which can keep the support plate in a horizontal state. When the arc-shaped protrusion presses down on the epaulette, the epaulette will deform downward and eventually form an arc-shaped structure. During the deformation of the epaulette, the side of the epaulette will displace a certain distance downward. After final shaping, there is a certain distance between the side of the epaulette and the limiting protrusion. The limiting protrusion can rotate with the support plate and is located between the arc-shaped protrusion and the arc-shaped groove. Attached Figure Description

[0043] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] Please refer to the following: Figures 1 to 12The present invention provides a shoulder strap shaping device. The shoulder strap shaping device includes an upper mold 1, a lower mold 2, a limiting protrusion 3, and a limiting structure 4. The bottom of the upper mold 1 has an arc-shaped protrusion 11; the top of the lower mold 2 has an arc-shaped groove 21 that mates with the arc-shaped protrusion 11; the lower mold 2 has support plates 5 on both sides of the arc-shaped groove 21, wherein the support plates 5 are hinged to the lower mold 2, and the hinge position has a rotary elastic element; the side wall of the arc-shaped groove 21 has a clearance groove 22 for accommodating the support plates 5; the limiting protrusion 3 is connected to the support plate 5 near the hinge axis; when the support plate 5 is horizontally positioned, the limiting protrusion 3 contacts the end of the shoulder strap to laterally limit the shoulder strap 6; the limiting structure 4 is located at the hinge position of the support plate 5 and is connected to the lower mold 2; when the support plate 5 rotates to a horizontal position under the elastic force of the rotary elastic element, the limiting structure 4 restricts the position of the support plate 5. For example, the rotational elastic element includes a torsion spring, which is sleeved on the hinge shaft of the support plate 5, and the two ends of the torsion spring are respectively connected to the hinge shaft and the lower mold 2; with the above arrangement, the torsion spring can apply torque to the hinge shaft, thereby causing the support plate 5 to rotate to a horizontal state.

[0045] The present invention provides a epaulette 6 shaping device. Compared with the prior art, the heated epaulette 6 is placed on the support plate 5, and the side of the epaulette 6 contacts the limiting protrusion 3, which can play a lateral limiting role for the epaulette 6, thereby reducing the occurrence of lateral displacement of the epaulette 6. By setting a rotary elastic element at the hinge position of the support plate 5, the support plate 5 can be rotated to a horizontal position under the elastic force of the rotary elastic element. The limiting structure 4 limits the support plate 5, which can keep the support plate 5 in a horizontal state. When the arc-shaped protrusion 11 presses down on the epaulette 6, the epaulette 6 will deform downward and eventually form an arc-shaped structure. During the deformation of the epaulette 6, the side of the epaulette 6 will be displaced downward by a certain distance. After the final shaping, there is a certain distance between the side of the epaulette 6 and the limiting protrusion 3. The limiting protrusion 3 can rotate with the support plate 5 and is located between the arc-shaped protrusion 11 and the arc-shaped groove 21.

[0046] In some embodiments, such as Figures 1 to 12 As shown, the top of the support plate 5 is curved. When the support plate 5 is located in the relief groove 22, the top of the support plate 5 is coplanar with the arc groove 21.

[0047] It should be noted that, since the top of the support plate 5 is set as a curved surface, the support plate 5 can be screwed into the relief groove 22 during the pressing of the shoulder epaulette 6. At this time, the curved surface on the support plate 5 is coplanar with the curved surface of the arc groove 21, which can support the shoulder epaulette 6 and facilitate the shaping of the shoulder epaulette 6.

[0048] In some embodiments, such as Figures 1 to 12As shown, the length of the limiting protrusion 3 is less than the thickness of the shoulder patch 6; when the upper mold 1 and the lower mold 2 cooperate to stamp the shoulder patch 6 and stamp it into place, the limiting protrusion 3 rotates to a horizontal position and is located in the gap between the arc protrusion 11 and the arc groove 21.

[0049] It should be noted that since the length of the limiting protrusion 3 is less than the thickness of the shoulder strap 6, the limiting protrusion 3 will be located between the arc protrusion 11 and the arc groove 21 during the stamping process of the shoulder strap 6, and will not interfere with the upper mold 1; therefore, after the limiting protrusion 3 completes its function of laterally limiting the shoulder strap 6, it will not interfere with the stamping process.

[0050] In some embodiments, such as Figures 1 to 12 As shown, the limiting protrusion 3 is a plate-shaped structure, and there is a preset angle between the limiting protrusion 3 and the support plate 5.

[0051] It should be noted that when the limiting protrusion 3 is a plate-shaped structure, the preset angle between the limiting protrusion 3 and the support plate 5 allows the support plate 5 to rotate into the clearance groove 22, so that the limiting protrusion 3 is in a horizontal state.

[0052] In some embodiments, such as Figures 1 to 12 As shown, the lower mold 2 is provided with baffles 23 at both ends of the arc groove 21 to longitudinally limit the shoulder strap 6.

[0053] It should be noted that the baffle 23 is fixed on the lower mold 2. When the shoulder strap 6 is placed in the arc groove 21, both ends of the shoulder strap 6 contact the two baffles 23 respectively. Therefore, the baffles 23 can play a role in longitudinally limiting the shoulder strap 6.

[0054] In some embodiments, such as Figures 1 to 12 As shown, the lower mold 2 has a rotating groove 24 at the hinge position of the support plate 5, and the limiting structure 4 includes a first limiting plate 41 and a second limiting plate 42; the first limiting plate 41 is connected to the support plate 5 and is close to the hinge position of the support plate 5; the second limiting plate 42 is connected to the inner side wall of the rotating groove 24; wherein, when the support plate 5 is rotated to a horizontal position, the top of the second limiting plate 42 contacts the bottom of the first limiting plate 41.

[0055] It should be noted that when there is no external force, the support plate 5 can rotate to a horizontal position under the elastic force of the rotating elastic element, and can maintain the horizontal state by contacting the first limiting plate 41 and the second limiting plate 42.

[0056] In some embodiments, such as Figures 1 to 12As shown, the second limiting plate 42 has a sliding groove 421, and a limiting rod 43 is slidably disposed in the sliding groove 421. An elastic element is sleeved on the limiting rod 43, and the two ends of the elastic element are respectively connected to the side wall of the limiting rod 43 and the sliding groove 421. One end of the limiting rod 43 can slide out of the sliding groove 421. The support plate 5 has a positioning hole 51 that is inserted into the limiting rod 43. When the support plate 5 is located in the clearance groove 22, the positioning hole 51 is aligned with the limiting rod 43, and the limiting rod 43 is inserted into the positioning hole 51 under the elastic force of the elastic element.

[0057] It should be noted that the elastic element includes spring 44; under the squeezing action of the arc-shaped protrusion 11, the shoulder epaulette 6 deforms into the arc-shaped groove 21, and the support plate 5 is screwed into the relief groove 22 under the pressing action. At this time, the positioning hole 51 on the support plate 5 is aligned with the limiting rod 43; the limiting rod 43 is engaged with the positioning hole 51 under the elastic force of spring 44, fixing the support plate 5 in the rotated state. Through the above settings, after the upper mold 1 is reset upward, the support plate 5 can be prevented from automatically springing upward.

[0058] In some embodiments, such as Figures 1 to 12 As shown, a guide ring 45 is connected to the side of the slide groove 421 away from the limiting rod 43. A pull rope 46 is provided in the slide groove 421. One end of the pull rope 46 is connected to the limiting rod 43, and the other end of the pull rope 46 passes through the guide ring 45 and extends to the upper surface of the lower mold 2. The upper surface of the lower mold 2 has a positioning structure to control the position of the pull rope 46 so that the limiting rod 43 is separated from the positioning hole 51.

[0059] It should be noted that by pulling the pull rope 46, the limiting rod 43 can slide in the slide groove 421 and separate the limiting rod 43 from the positioning hole 51 on the support plate 5. At this time, it is convenient for the support plate 5 to rotate in the opposite direction and reset. By setting the positioning structure, the limiting rod 43 can be kept in the retracted state. The operator does not need to pull the pull rope 46 continuously during the reset of the support plate 5, which can save the operator's physical strength.

[0060] In some embodiments, such as Figures 1 to 12 As shown, the positioning structure includes a slide rail 47, a slider 48, and a plug rod 49; the slide rail 47 is connected to the upper surface of the lower mold 2; the slide rail 47 faces the rotating groove 24; the slider 48 is slidably disposed on the slide rail 47; the slider 48 has a first insertion hole, and the lower mold 2 has a second insertion hole 25 for alignment with the first insertion hole; the other end of the pull rope 46 is connected to the slider 48; the plug rod 49 is disposed on the slider 48; the plug rod 49 is used to engage with the first insertion hole and the second insertion hole 25; wherein, when the plug rod 49 engages with the first insertion hole and the second insertion hole 25, the limiting rod 43 separates from the positioning hole 51.

[0061] It should be noted that by sliding the slider 48 to the position where the first and second insertion holes 25 are aligned, and by inserting the rod 49 into the first and second insertion holes 25, the pull rope 46 can pull the limiting rod 43 back to the slide groove 421 and put the limiting rod 43 in a retracted state; when the support plate 5 rotates to a horizontal state, the rod 49 is pulled out, and at this time the limiting rod 43 can abut against the hinge axis position of the support plate 5 under the elastic force of the spring 44.

[0062] For example, there are several support plates 5. This embodiment uses one support plate 5 as an example for explanation. After the shoulder patch 6 is shaped, the upper mold 1 is reset upwards. The operator can drive the pull rope 46 to move by sliding the slider 48, and finally separate the limiting rod 43 from the positioning hole 51. At this time, by inserting the rod 49 into the first insertion hole and the second insertion hole 25, the limiting rod 43 can be in a state separated from the positioning hole 51. The operator can hold the limiting protrusion 3 on the support plate 5 and rotate the support plate 5 in the opposite direction to form a gap between the shoulder patch 6 and the arc groove 21, so that the operator can easily take the shoulder patch 6 out of the lower mold 2. After the shoulder patch 6 is taken out, all the support plates 5 are reset, and the rod 49 is separated from the first insertion hole and the second insertion hole 25, so that the limiting rod 43 is pressed against the side wall of the support plate 5 at the hinge axis position.

[0063] It should be noted that when the operator rotates the support plate 5 in the opposite direction, the support plate 5 rotates in the opposite direction under the combined action of the torsion spring and the operator's grip, which can save the operator's physical strength. Then, one side of the shaped epaulette 6 is disengaged from the arc groove 21, making it easier for the operator to remove the entire epaulette 6 from the arc groove 21.

[0064] In some embodiments, such as Figures 1 to 12 As shown, a roller 7 is rotatably mounted on the lower mold 2 near the rotating groove 24, and the pull rope 46 rotates in coordination with the roller 7.

[0065] It should be noted that the roller 7 is connected to the lower mold 2 via the support 71; by setting the roller 7 on the lower mold 2, the pull rope 46 and the roller 7 can roll together, reducing the wear between the pull rope 46 and the lower mold 2.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
