Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing, specifically to a flattening device. Background Technology

[0002] In the garment manufacturing industry, especially in the production of outdoor jackets, a typical outdoor jacket is made by piecing together several pieces of fabric. After piecing, the seams will naturally curl up. These curled-up parts need to be flattened before applying glue to achieve good waterproof performance. Currently, the method for dealing with the curled-up parts of outdoor jackets is to use a hot-melt flattening device to flatten the curled-up parts while simultaneously applying glue, thus achieving both flattening and fixing. The hot-melt flattening device has a pressure roller and a lower roller. The pressure roller can be raised or lowered to contact or move away from the lower roller. When the pressure roller is in contact with the lower roller, it can rotate independently, driving the lower roller to rotate. The operator places the curled-up part onto the lower roller, where the two rollers contact... At the front, a tool is used to flatten the raised part to one side, and the pressure roller sinks down to meet the lower roller. The rotation of the pressure roller drives the lower roller to rotate, feeding the fabric into the contact area to flatten it and apply adhesive. This operation method has safety hazards. Since the raised part does not flatten to one side on its own, the operator needs to be close to the contact area between the two rollers, holding a tool to apply force to the raised part to make it flatten to one side. Because the position is too close to the contact area, it is easy to accidentally get the tool caught in the guide equipment, and in severe cases, the hand may also be caught in it. This processing method has great safety hazards, which may at least force the work to stop and reduce production efficiency, or at worst lead to personal injury or death. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a flattening device that improves safety and ensures production efficiency during the production process.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a flattening device for flattening the raised portion of sewn fabric. The flattening device includes an abutting surface and a pressing roller that moves relative to the abutting surface. The pressing roller moves relative to the abutting surface in a first direction to abut the abutting surface, and moves relative to the abutting surface in the opposite direction of the first direction to move away from the abutting surface. The flattening device further includes an elastic pressure plate with a fixed end and a pressing end. The fixed end is fixed relative to the pressing roller, and the pressing end is adapted to press against the abutting surface. When the pressing roller moves in the first direction to abut the abutting surface, the pressing end presses the raised portion against the abutting surface, causing it to flatten to one side. When the pressing roller abuts the abutting surface, the pressing end is located behind the pressing roller along the extension direction of the raised portion.

[0006] The second technical solution is based on the first technical solution. The pressing end is a square plate with a downward guiding surface. Its width is wider than the abutting surface. The guiding surface is a slope that is lower on the left and higher on the right, which is suitable for making the raised part easy to fall to one side.

[0007] The third technical solution is based on the second technical solution. The guide surface is further provided with a downwardly extending guide iron plate. The guide iron plate extends downward from the guide surface and is perpendicular to the abutment surface.

[0008] The fourth technical solution is based on the first technical solution. The flattening device is further provided with a lower wheel. The pressing wheel moves along the first direction to abut against the lower wheel to abut against the contact surface. The pressing wheel moves in the opposite direction of the first direction to move away from the lower wheel to move away from the contact surface.

[0009] The fifth technical solution is based on the first technical solution, wherein the pressing roller is covered with an adhesive film, and the adhesive film falls down while the pressing roller flattens the raised part.

[0010] The sixth technical solution is based on the first technical solution, wherein the fixed end is provided with a through hole, and the through hole is elongated.

[0011] The seventh technical solution is based on the first technical solution, wherein the elastic pressure plate is made of 304 stainless steel.

[0012] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0013] 1. In the first technical solution, the pressing roller of the flattening device can move relative to the contact surface to achieve contact or movement away from the contact surface, allowing for manual intervention to interrupt the flattening process. When the raised portion is not flattened according to the preset trajectory, or when the fabric deviates during the flattening process, failing to effectively flatten the raised portion, or when other items are accidentally caught in the contact surface, the flattening device can be manually intervened to move the pressing roller away from the contact surface, removing the fabric and other items accidentally caught in the contact surface, thereby ensuring production safety and quality. The elastic pressure plate has a fixed end and a pressing end. The fixed end is fixed relative to the pressing roller, so that when the pressing roller moves in the first direction, the elastic pressure plate, with its fixed end fixed relative to the pressing roller, can move along with the pressing roller. When the pressing roller contacts the contact surface, the pressing end of the elastic pressure plate also contacts the contact surface, pressing the raised portion against the contact surface and causing it to fall to one side. This ensures that the raised portion always falls to one side in the expected direction during the flattening process, eliminating the need for manual intervention. To continuously adjust the direction of the bending, safety and efficiency are improved. Furthermore, when the pressure end abuts the contact surface, the elastic pressure plate is positioned behind the pressure roller along the extension direction of the raised portion. This has the advantage that, with the elastic pressure plate behind the contact surface, operation can be performed at the pressure end when bending the raised portion to one side. After the raised portion is designated to be bent to one side, the pressure end helps to hold down the bent portion, and the rollers then guide the bent portion into the contact surface for flattening. Without the auxiliary pressure of the pressure end, the raised portion would need to be flattened to one side near the contact surface. When the machine starts, the rolling wheels could pull the object applying pressure to the raised portion into the contact surface, causing a safety accident. The pressure end, located behind the pressure wheel along the extension direction of the raised portion, further avoids this. It is a distance from the contact surface, and by flattening the raised portion to one side, the pressure end provides auxiliary pressure, further enhancing safety. Furthermore, the elastic pressure plate itself has a certain degree of elasticity and freedom. During operation, if the pressure plate collides with the pressure wheel or lower wheel due to improper operation or other reasons, the pressure plate will spring back or deform due to its own elasticity, preventing direct damage or destruction to the flattening device.

[0014] 2. In the second technical solution, the pressing end used to press down the raised part is set as a square plate structure, and the width is greater than the abutting surface. The purpose is to increase the coverage area, reduce the difficulty of operation, and facilitate the guiding surface to press down on the raised part. In order to facilitate providing a falling trajectory for the raised part, the guiding surface is designed as a slope with the left side lower and the right side higher. When it abuts against the abutting surface, it forms an angle. Under the pressing action, the raised part gradually falls to the right side as the pressing end falls down.

[0015] 3. In the third technical solution, the function of the guide iron plate is to keep the fabric against the other side of the raised part as the fabric is continuously fed into the contact surface. The guide iron plate will check whether the fabric deviates from the preset route. When the guide iron plate senses that the raised part is gradually deviating, it will adjust the fabric in time to ensure that the raised part always enters the contact surface along the preset route and is flattened.

[0016] 4. In the fourth technical solution, the contact surface is formed by the outer circumferential surface of the lower wheel. The advantage of this design is that it improves the degree of automation, increases production efficiency, and reduces manufacturing costs. Flattening the raised part requires feeding the fabric to the contact surface. By setting the device below as a wheel, the lower wheel can be rotated by the self-drive of the pressure wheel, thereby automatically rolling the raised part placed at the lower wheel into the contact surface for flattening. This eliminates the need for manual pushing of the fabric to the contact surface, thus improving the degree of automation and production efficiency. In addition, the lower wheel is fed by friction transmission of the pressure wheel, which has a single power source, saving on power source investment and reducing manufacturing costs.

[0017] 5. In the fifth technical solution, in order to ensure that the raised part does not spring back and deform after being flattened, the pressure roller is covered with an adhesive film, which can apply adhesive while flattening to fix the flattened part and prevent the raised part from springing back and deforming after being flattened.

[0018] 6. In the sixth technical solution, the fixed end of the elastic pressure plate is provided with a through hole, which is suitable for fasteners such as bolts to pass through, so that the fixed end can be installed in a detachable and adjustable manner. The purpose of setting the through hole as a strip is to adjust the relative position between the elastic pressure plate and the flattening device by moving the position of the bolt in the through hole.

[0019] 7. In the seventh technical solution, the advantage of using 304 stainless steel is that, due to its excellent machinability and toughness, it is easy to process into various shapes. In this patent, in order for the elastic pressure plate to move together with the pressing wheel, the pressing end also abuts against the pressing surface when the pressing wheel contacts the abutting surface. In order to prevent the elastic pressure plate from interfering with the operation of other components, the elastic pressure plate needs to be made into a specific shape, which requires a certain degree of plasticity of the material. 304 stainless steel meets this requirement. In addition, during the processing, considering that the elastic pressure plate acts directly on the fabric, in order to avoid safety problems caused by improper operation by the operator, when the elastic pressure plate is subjected to a large external force impact, it will deform itself instead of directly acting on the lower wheel or fixed end and causing damage to the equipment. Furthermore, the corrosion resistance of 304 stainless steel can ensure its long service life. Attached Figure Description

[0031] See Figure 1 , Figure 1 The image shows the raised portion 1. The raised portion 1 is formed by splicing two pieces of fabric together. The two pieces are laid flat to form a plane, and the part that protrudes from this plane is called the raised portion 1.

[0032] See Figure 2 , Figure 2 A schematic diagram of the flattening device 2 is shown. The flattening device 2 is used to flatten the raised part 1 produced by the spliced ​​cut pieces to ensure the flatness and appearance of the clothing fabric. The flattening device 2 includes a pressing roller 4, a contact surface 3, and an elastic pressure plate 5; the contact surface 3, in this embodiment, is formed by the outer circumferential surface of the lower roller 8, suitable for the raised part 1 to pass through, and cooperates with the pressing roller 4 to flatten the raised part 1; the pressing roller 4, the surface of the pressing roller 4 is covered with an adhesive film 9, the pressing roller 4 can move relative to the contact surface 3, in this embodiment, the pressing roller 4 can move relative to the lower roller 8, the pressing roller 4 can move in a first direction to abut the contact surface 3 (lower roller 8), in this embodiment the first direction is downward, the pressing roller 4 can move in an upward direction to move away from the contact surface 3; the lower roller 8, is located below the pressing roller 4; the elastic pressure plate 5, the elastic pressure plate 5 is made of 304 stainless steel, it includes a fixed end 6 and a pressing end 7: the fixed end 6 is fixed relative to the pressing roller 4, and the pressing end 7 abuts the contact surface 3.

[0033] See Figure 2 , Figure 2 The diagram shows the structure of the elastic pressure plate 5. The elastic pressure plate 5 includes a fixed end 6 and a pressing end 7. The fixed end 6 has a through hole 61 and is fixed to the pressing wheel 4. The pressing end 7 is adapted to abut against the pressing surface 3. The pressing end 7 is square in shape. The side of the pressing end that contacts the pressing surface 3 has a guide surface 71. The width of the guide surface 71 in the left-right direction is wider than the width of the pressing surface 3. The guide surface 71 is in a left-low-right-high posture and forms an angle with the pressing surface 3 when it abuts against it. A guide iron plate 711 is also provided below the guide surface 71. When the guide iron plate 711 contacts the pressing surface 3, it is perpendicular to the pressing surface. It is adapted to stick tightly to the raised part 1 during the flattening process to sense whether the raised part 1 is sent into the pressing surface 3 according to the preset route for flattening.

[0034] In this embodiment, the flattening device 2 is divided into upper and lower structures. The pressure roller 4 is driven by a motor and is located at the upper part, while the lower roller 8 is located at the lower part. The elastic pressure plate 5 has a fixed end 6 that is fixed to the pressure roller 4 by bolts. The elastic pressure plate 5 moves with the pressure roller 4. Specifically, when the pressure roller 4 moves downward, the fixed end 6 of the pressure roller 4 drives the elastic pressure plate 5 to move in the same direction. When the pressure roller 4 abuts against the abutting surface 3 (lower roller 8), the pressure end 7 of the elastic pressure plate 5 also abuts against the abutting surface 3 at the same time. More specifically, when the lower roller 8 is placed on the raised part 1 that needs to be flattened, the pressure roller 4 moves downward, and the elastic pressure plate 5 moves with the pressure roller 4. When the pressure roller 4 abuts against the abutting surface 3, the guide surface 71 contacts the abutting surface 3, and the guide iron plate 711 below the guide surface 71 abuts against the lower roller 8. On one side of the raised part 1 on the wheel 8, the guide surface 71 presses the raised part 1 against the abutting surface 3 and makes it fall to the other side. The pressing wheel 4 is driven by the motor to start rotating counterclockwise. The friction transmission drives the lower wheel 8 to rotate clockwise. The lower wheel 8 carries the raised part 1 to the abutting surface 3 for flattening. At the same time as flattening, the adhesive film 9 on the pressing wheel 4 will automatically fall to the flattened part to ensure that it does not rebound and deform. The fabric that has been flattened and glued will gradually move to the front of the pressing wheel 4 as the pressing wheel 4 rotates. The pressing end 7 of the elastic pressure plate 5 is located behind the pressing wheel 4 to ensure that the raised part 1 is always pressed against the abutting surface 3 by the guide surface 71 and falls to one side. When the flattening work is completed, the pressing wheel 4 moves upward to move away from the abutting surface 3 (lower wheel 8), and the elastic pressure plate 5 follows the movement of the pressing wheel 4 to move away from the abutting surface 3.

[0035] The specific implementation method is as follows: Place the spliced ​​cut piece with the raised portion 1 onto the lower wheel 8 of the flattening device 2, apply pressure to the raised portion 1, causing it to abut against the contact surface 3 and fall to one side; turn on the drop button, causing the pressure roller 4 to move downwards to abut against the contact surface 3. At this time, the guide iron plate 711 abuts against the other side of the raised portion 1, and the guide surface 71 presses down on the raised portion 1 that has fallen to one side and is located behind the pressure roller 4; start the drive motor of the pressure roller 4, and the pressure roller 4 begins to rotate counterclockwise. Friction drive drives the lower wheel 8 to rotate, and the rotation of the lower wheel 8 drives the fabric to the contact point between the two wheels. The operator holds both sides of the cut piece and senses whether one side of the raised part 1 is in close contact with the guide iron plate 711 to ensure that the cut piece is conveyed to the contact point between the two wheels according to the preset trajectory for flattening. The raised part 1 that has fallen to one side is flattened when it passes the contact point between the two wheels and is fixed by the adhesive film 9. After being flattened and fixed, it is output from the front of the pressure roller 4 until the raised part 1 is completely processed. The pressure roller 4 is raised and the machine is turned off.

[0036] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
