Description

Technical Field

[0001] The invention belongs to the technical field of fabric processing, and in particular relates to a secondary hot pressing composite device for down jacket fabrics. Background Art

[0002] The hot-pressing composite process for down jacket fabrics involves spraying glue on an injection-molded skeleton, heating it, and then manually wrapping the fabric. The fabrics for hot-pressing composites generally have back foam and non-woven fabrics. During composite work, the non-woven fabric can prevent the glue from penetrating into the foam and fabric, thus avoiding uneven fabric thickness.

[0003] In the prior art, most secondary hot pressing devices use an upper pressing plate that slides downward directly to perform hot pressing, and workers are responsible for loading and unloading materials. However, both the upper and lower pressing plates have high temperatures. When workers place fabrics, the upper pressing plate is located directly above them, and they are prone to touching the upper pressing plate and getting burned. When laying fabrics, they are also prone to getting burned by the lower pressing plate, making the operation dangerous. Summary of the Invention

[0004] The purpose of the present invention is to provide a down jacket fabric secondary hot pressing composite device in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A down jacket fabric secondary hot pressing composite device includes a bottom plate, vertical frames and a top plate for forming a frame structure, and also includes:

[0007] The first hot pressing structure includes an upper hot pressing plate, a connecting rod hinged to the edge of the upper hot pressing plate, a motor provided at the lower end of the top plate, and a threaded sliding pair driven by the motor and hinged to the connecting rod;

[0008] The second hot pressing structure includes a horizontally sliding lower hot pressing plate and sliding blocks arranged on both sides of the lower hot pressing plate;

[0009] The transmission structure is used to synchronously transmit the motion of the threaded sliding pair to the sliding block through a hydraulic structure.

[0010] As a further optimization scheme of the present invention, a first heating plate is provided at the bottom end of the upper hot pressing plate, and a vibration block in contact with the first heating plate, an electromagnetic generator for attracting the vibration block, and a spring for pushing the vibration block are provided inside the upper hot pressing plate. By setting multiple groups of vibration blocks, a multi-point vibration mode is formed during hot pressing, which can make the glue distribution more uniform.

[0011] As a further optimization scheme of the present invention, a square frame is fixedly connected between the sliding blocks, and the lower hot pressing plate is set inside the square frame for sliding up and down. The bottom end of the lower hot pressing plate is provided with a slide groove with a gradient depth, and the surface of the bottom plate is provided with a lifting guide wheel corresponding to the slide groove. During hot pressing, the lower hot pressing plate will move up. When hot pressing is completed and unloading is completed, the lower hot pressing plate will descend, so that the heat source is reduced to prevent the staff from being scalded during operation.

[0012] As a further optimization scheme of the present invention, the upper surface of the square frame is provided with a fine mesh plate for supporting the fabric, the upper surface of the lower hot pressing plate is provided with a second heating plate, and the upper surface of the second heating plate is provided with a groove adapted to the fine mesh plate. The fabric can be supported by the fine mesh plate to facilitate loading. During hot pressing, the second heating plate moves up and cooperates with the first heating plate for hot pressing. In order to prevent the fine mesh plate from causing indentations, a groove that fits the fine mesh plate is provided on the surface of the second heating plate.

[0013] As a further optimization scheme of the present invention, the side surface of each of the square frames is connected to at least four sliding blocks, and a fixed rod serving as a sliding block track is provided inside the vertical frame, so that the sliding of the square frame is more stable and moves horizontally after the hot pressing is completed, away from the upper hot pressing plate, which is convenient for the staff to operate.

[0014] As a further optimization scheme of the present invention, the transmission structure includes a first hydraulic push rod and a second hydraulic push rod, the sliding end of the first hydraulic push rod is connected to the threaded sliding pair, the fixed end of the first hydraulic push rod is provided with a first connecting port, the sliding end of the second hydraulic push rod is connected to the sliding block, and the fixed end of the second hydraulic push rod is provided with a second connecting port connected to the first connecting port. The transmission structure is hydraulically transmitted so that when the upper hot press plate moves downward, the lower hot press plate is automatically aligned, and when the upper hot press plate rises, the lower hot press plate automatically moves away, which facilitates operation and prevents burns.

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a lower hot pressing plate that can move in two dimensions, so that during the process of hot pressing and taking out materials, the lower hot pressing plate moves horizontally away from the upper hot pressing plate, and at the same time sinks, so that the operator is away from the heat source during the process of taking and placing the fabric, which has a good protection effect and prevents the operator from being scalded.

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1-5 As shown, a secondary hot pressing composite device for down jacket fabrics includes a bottom plate 11, a vertical frame 12 and a top plate 13 for constituting a frame structure 1, and also includes a first hot pressing structure 2, a second hot pressing structure 3, and a transmission structure 4.

[0026] The first hot pressing structure 2 includes an upper hot pressing plate 24 , a connecting rod 23 hinged to the edge of the upper hot pressing plate 24 , a motor 21 arranged at the lower end of the top plate 13 , and a threaded sliding pair 22 driven by the motor 21 and hinged to the connecting rod 23 .

[0027] The second hot pressing structure 3 includes a horizontally sliding lower hot pressing plate 35 and sliding blocks 32 arranged on both sides of the lower hot pressing plate 35 .

[0028] The transmission structure 4 is used to synchronously transmit the movement of the threaded sliding pair 22 to the sliding block 32 through the hydraulic structure. The transmission structure 4 includes a first hydraulic push rod 41 and a second hydraulic push rod 43. The sliding end of the first hydraulic push rod 41 is connected to the threaded sliding pair 22, and the fixed end of the first hydraulic push rod 41 is provided with a first connecting port 42. The sliding end of the second hydraulic push rod 43 is connected to the sliding block 32, and the fixed end of the second hydraulic push rod 43 is provided with a second connecting port 44 that is connected to the first connecting port 42.

[0029] Operating principle: The motor 21 drives the threaded sliding pair 22 to move, the threaded sliding pair 22 drives the connecting rod 23 to move, and the connecting rod 23 drives the upper hot pressing plate 24 to move downward. While the threaded sliding pair 22 is moving, it applies thrust to the first hydraulic push rod 41. The first hydraulic push rod 41 transmits the pressure to the second hydraulic push rod 43 through the pipeline. The second hydraulic push rod 43 pushes the sliding block 32 to slide along the fixed rod 31, driving the lower hot pressing plate to slide horizontally and move to the bottom of the upper hot pressing plate 24. After the hot pressing is completed, the threaded sliding pair 22 moves back, and the upper hot pressing plate 24 moves upward while the lower hot pressing plate 35 moves away from the bottom of the upper hot pressing plate 24.

[0030] In order to improve the bonding effect of the glue, a first heating plate 2404 is provided at the bottom end of the upper hot pressing plate 24. The interior of the upper hot pressing plate 24 is provided with a vibration block 2402 in contact with the first heating plate 2404, an electromagnetic generator 2401 for attracting the vibration block 2402, and a spring 2403 for pushing the vibration block 2402. During operation, the electromagnetic generator 2401 generates pulsed electromagnetic energy, which cooperates with the spring 2403 to cause the vibration block 2402 to vibrate up and down. The distributed point vibration of the array can fully cover the entire area to avoid vibration attenuation.

[0031] It should be noted that during operation, the following problem may be encountered: when the upper hot pressing plate 24 moves downward and is about to contact the lower hot pressing plate 35, the upper and lower surfaces of the fabric have already contacted the two hot pressing plates, but the two hot pressing plates still have relative movement in the horizontal direction (the lower hot pressing plate 35 is still moving horizontally under the push of the second hydraulic push rod 43), which can easily cause fabric wrinkles. In order to solve this problem, Figure 3 As shown, the connection between the second hydraulic push rod 43 and the sliding block 32 is set to an elastic push type rather than a fixed connection. When the sliding block 43 moves to the farthest end, the lower hot pressing plate 35 is aligned with the upper hot pressing plate 24. At this time, when the second hydraulic push rod 43 continues to push, the elastic element can be used for spatial buffering to avoid wrinkles in the fabric.

[0032] Example 2

[0033] When the hot pressing is completed and the lower hot pressing plate 35 moves horizontally away from the bottom of the upper hot pressing plate 24, in order to prevent the second heating plate 36 on the surface of the lower hot pressing plate 35 from scalding the staff, this embodiment adds the function of automatic lifting of the lower hot pressing plate 35 compared to Example 1. When the lower hot pressing plate 35 is close to the bottom of the upper hot pressing plate 24, the lower hot pressing plate 35 rises, and vice versa. In order to achieve this purpose, a square frame 33 is fixedly connected between the sliding blocks 32, and the lower hot pressing plate 35 is set inside the square frame 33 for sliding up and down. A depth gradient slide groove 37 is provided at the bottom end of the lower hot pressing plate 35, and a lifting guide wheel 38 corresponding to the slide groove 37 is provided on the surface of the bottom plate 11.

[0034] The upper surface of the square frame 33 is provided with a fine mesh plate 34 for supporting the fabric, the upper surface of the lower hot pressing plate 35 is provided with a second heating plate 36, and the upper surface of the second heating plate 36 is provided with a groove adapted to the fine mesh plate 34. The side surface of each square frame 33 is connected to at least four sliding blocks 32, and the interior of the vertical frame 12 is provided with a fixed rod 31 serving as a track for the sliding block 32.

[0035] During operation, the fine mesh plate 34 is used to lay the fabric, and the second heating plate 36 is in Figure 4 In the position shown, no burns will be caused. During hot pressing, the box 33 slides horizontally, driving the lower hot pressing plate 35 to move horizontally. The lifting guide wheel 38 enters a shallow section in the slide groove 37, lifting the lower hot pressing plate 35. When the hot pressing is completed and the material is taken, the lower hot pressing plate 35 descends, avoiding contact between the staff and the lower hot pressing plate 35.

[0036] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
