Description

Technical Field

[0001] The invention relates to the technical field of heat presses, and in particular to a nonwoven fabric heat press. Background Art

By setting the first supporting assembly, motor, bidirectional screw and guide rod, the device can place the non-woven fabric at different inclination angles according to the size of the non-woven fabric to be processed when in use. When the width of the non-woven fabric is wider, the bidirectional screw can be driven by the motor to rotate, so that the distance between the second hot pressing plate and the third hot pressing plate on the device is increased, so that the device can adapt to the use of non-woven fabrics of different sizes.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0023] like Figure 1-Figure 9As shown, this embodiment proposes a non-woven fabric hot press, including a base plate 1, a first electric push rod 2 is installed on the base plate 1, a first connecting plate 6 is fixedly connected to the outer side of the first electric push rod 2, a second connecting plate 7 is fixedly connected to the top of the first electric push rod 2, the structure on the second connecting plate 7 is the same as the structure on the first connecting plate 6 but in the opposite direction, a first support assembly 3 is installed on the side of the base plate 1, a docking assembly 4 is installed on the first support assembly 3, a second support assembly 5 is installed on the docking assembly 4, and a third electric heating tube 23 is installed on the second support assembly 5. During the process of feeding in and out the non-woven fabric, the third electric heating tube 23 can preheat and step-by-step cool the non-woven fabric, thereby improving the processing quality of the non-woven fabric. The first supporting assembly 3 is used to change the positions of the two groups of second supporting assemblies 5 so as to subsequently change the feeding direction of the non-woven fabric. When the size of the non-woven fabric is too wide, the hot pressing range can be increased by oblique feeding. A motor 8 is installed on the first connecting plate 6 on the rear side, and a bidirectional screw 9 is fixedly connected to the output shaft of the motor 8. A guide rod 12 is fixedly connected to the first connecting plate 6. The guide rod 12 and the bidirectional screw 9 are sequentially installed with a third hot pressing plate 16, a first hot pressing plate 11 and a second hot pressing plate 14 from front to back. A first electric heating tube 18 is installed in each plate 14, a second heat conducting plate 13 is fixedly connected to the top of the first hot pressing plate 11, a third heat conducting plate 15 is fixedly connected to the top of the second hot pressing plate 14, a fourth heat conducting plate 17 is fixedly connected to the top of the third hot pressing plate 16, a hot pressing assembly 22 is installed in the middle of the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17, a fifth heat conducting plate 20 is fixedly installed on the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17, and a second electric heating tube 21 is fixedly arranged in the fifth heat conducting plate 20. When the device is in use, the motor 8 can drive the bidirectional screw 9 to rotate, driving the second hot pressing plate 14 and the third hot pressing plate 16 to move back to back or towards each other, so as to further adjust the hot pressing range of the device. When hot pressing the non-woven fabric, after the first electric heating tube 18 is energized, the first hot pressing plate 11, the second hot pressing plate 14 and the third hot pressing plate 16 transfer heat to the surfaces of the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17. By shortening the first electric push rod 2, the first connecting plate 6 and the second connecting plate 7 are brought close to each other, so that the upper and lower groups of the second heat conducting plates 13, the third heat conducting plates 15 and the fourth heat conducting plates 17 of the device are brought close to each other, realizing the hot pressing function of the non-woven fabric. According to the entry angle of the non-woven fabric, the angle of the hot pressing assembly 22 can be adjusted so that the non-woven fabric can be stably fed in and out. Example 2

[0024] like Figure 1-Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a non-woven fabric heat press.

[0025] In this embodiment, the first support assembly 3 includes a guide rail 301 fixedly connected to the left and right sides of the base plate 1, a slider 302 is slidably installed in the guide rail 301, a connecting rod 303 is fixedly connected between two adjacent sliders 302, and a second electric push rod 304 is fixedly connected to the slider 302. The connecting rod 303 enables the two sliders 302 on the device to slide at the same time, and the connecting line of the two sliders 302 always passes through the central axis of the device. After the slider 302 slides in the guide rail 301, it can adapt to the use of non-woven fabrics with wider sizes, thereby enhancing the scope of application of the device.

[0026] In this embodiment, the docking assembly 4 includes a first connecting block 401 fixedly connected to the top of the second electric push rod 304, a docking block 402 is slidably installed in the first connecting block 401, a clamping rod 403 is fixedly connected to the docking block 402, a first spring 404 is fixedly arranged at the bottom of the clamping rod 403, a sliding rod 409 is fixedly connected to the clamping rod 403, a second connecting block 405 is arranged on the outer side of the sliding rod 409, the sliding rod 409 protrudes from the surface of the second connecting block 405, a second spring 406 is installed between the sliding rod 409 and the second connecting block 405, a third connecting block 407 is arranged above the second connecting block 405, and the second connecting block 405 and the third connecting block 407 are connected. A hinge 408 is installed in the middle. After the winding is completed, the third connecting block 407 above the second connecting block 405 can be rotated through the hinge 408. When the third connecting block 407 rotates, it can resist the sliding rod 409. After the sliding rod 409 is resisted, it will shrink to the inside of the second connecting block 405. At this time, the second spring 406 is compressed, and the card rod 403 slides inside the docking block 402 until the card rod 403 is completely moved to the inside of the docking block 402. At this time, under the action of the first spring 404, the docking block 402 will be pushed out, thereby realizing the function of automatic disengagement, and the second connecting block 405 can be reinstalled to the inside of the first connecting block 401 according to the above reverse steps.

[0027] In this embodiment, the first spring 404 and the first connecting block 401 are abutted against each other, the central axes of the first connecting block 401, the second connecting block 405 and the third connecting block 407 are collinear, and the docking block 402 and the second connecting block 405 are fixedly connected. When the second connecting block 405 on the device is out of the engaged state, the first spring 404 can lift the second connecting block 405 as a whole, ensuring that the docking block 402 can be stably detached from the inside of the first connecting block 401, making the device more convenient when removing the non-woven fabric roll after hot pressing.

[0028] In this embodiment, the second supporting assembly 5 includes a first heat conducting plate 501 fixedly connected to the third connecting block 407, and damping blocks 502 are slidably installed on both sides of the first heat conducting plate 501, a connecting plate 503 is fixedly connected to the damping block 502, a damping ring 505 is fixedly installed on the connecting plate 503, and a support rod 504 is installed in the damping ring 505. The third electric heating tube 23 and the connecting plate 503 are fixedly connected, and the support rod 504 on the device is used for winding non-woven fabrics. As the diameter of the non-woven fabric roll gradually increases, the connecting plate 503 will gradually slide in the first heat conducting plate 501 through the damping block 502. During this process, the third electric heating tube 23 gradually approaches the first heat conducting plate 501, so that the device can be preheated when unwinding the non-woven fabric. When winding the non-woven fabric, gradient cooling can be performed as the non-woven fabric is wound, thereby improving the production quality of the non-woven fabric.

[0029] In this embodiment, the first connecting plate 6 and the second connecting plate 7 are symmetrically distributed on the front and rear sides of the base plate 1, and the first electric push rod 2 is symmetrically distributed on the left and right sides of the first connecting plate 6 and the second connecting plate 7. The first connecting plate 6 and the second connecting plate 7 are parallel to each other. The parallel first connecting plate 6 and the second connecting plate 7 allow the device to remain stable when hot pressing the front and back sides of the non-woven fabric at the same time, thereby ensuring the stability of the device during operation. The first electric push rod 2 is used to adjust the distance between the first connecting plate 6 and the second connecting plate 7, thereby evenly hot pressing the non-woven fabric.

[0030] In this embodiment, a movable groove 19 for the fifth heat conducting plate 20 to move is provided on the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17. The upper surface of the fourth heat conducting plate 17 is flush with the upper surfaces of the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17. When the upper and lower groups of the second heat conducting plates 13, the third heat conducting plates 15 and the fourth heat conducting plates 17 are close to each other, they can simultaneously perform heat pressing treatment on the upper and lower sides of the non-woven fabric. The movable groove 19 enables the hot pressing range of the device to fill the gap between adjacent heat conducting plates when it is extended.

[0031] In this embodiment, the third hot pressing plate 16 and the second hot pressing plate 14 are both threadedly connected to the bidirectional screw 9, and the third hot pressing plate 16 and the second hot pressing plate 14 are both slidably connected to the guide rod 12. The bottom of the first hot pressing plate 11 below is fixedly connected with a pillar 10, and the bottom of the pillar 10 is fixedly connected to the bottom plate 1. The bidirectional screw 9 and the guide rod 12 are both rotatably connected to the first hot pressing plate 11. When the bidirectional screw 9 rotates, the third hot pressing plate 16 and the second hot pressing plate 14 can move toward or away from each other, and the guide rod 12 ensures that the third hot pressing plate 16 and the second hot pressing plate 14 can only move forward and backward, so that the device can adapt to non-woven fabrics of different widths for hot pressing treatment.

[0032] In this embodiment, the hot pressing assembly 22 includes a rotating ring 2203 rotatably mounted on the second heat conducting plate 13, the third heat conducting plate 15 and the fourth heat conducting plate 17, the interior of the rotating ring 2203 is fixedly connected to the fourth hot pressing plate 2201, a sealing gasket 2204 is fixedly arranged inside the fourth hot pressing plate 2201, a sealing ring 2205 is fitted on the sealing gasket 2204, and a rotating wheel 2202 is fitted inside the sealing ring 2205. During the hot pressing process of the non-woven fabric, the rotating ring 2203 can be rotated according to the feeding direction of the non-woven fabric, thereby changing the angle of the fourth hot pressing plate 2201, so that the rotating wheel 2202 is perpendicular to the feeding direction of the non-woven fabric, so that the rotating wheel 2202 can press the non-woven fabric during the hot pressing process and can also rotate, so that the non-woven fabric remains flat.

[0033] In this embodiment, the rotating wheels 2202 protrude from the surface of the fourth hot pressing plate 2201, and the rotating wheels 2202 are evenly spaced on the fourth hot pressing plate 2201. The sealing pad 2204 is a hemispherical cover structure. The positions of the rotating wheels 2202 on the upper fourth hot pressing plate 2201 and the rotating wheels 2202 on the lower fourth hot pressing plate 2201 are staggered with each other, ensuring that the non-woven fabric can be pressed by multiple rotating wheels 2202, thereby ensuring the hot pressing effect of the device. The sealed cavity formed between the sealing pad 2204, the sealing ring 2205 and the rotating wheel 2202 can reset the rotating wheel 2202 after the rotating wheel 2202 is compressed.

[0034] Specifically, the present invention is a nonwoven heat press, first, as Figure 1-Figure 5 As shown, the bottom plate 1 and the support 10 are used to support the whole device. By extending or shortening the first electric push rod 2, the spacing between the first connecting plate 6 and the second connecting plate 7 changes, so as to adapt to the non-woven fabrics of different thicknesses for double-sided hot pressing treatment. When hot pressing the non-woven fabrics with a wider width, the bidirectional screw 9 is driven to rotate by the motor 8, and the guide rod 12 ensures that the third hot pressing plate 16 and the second hot pressing plate 14 can only move forward and backward. At this time, the third hot pressing plate 16 and the second hot pressing plate 14 can move toward each other or move back to back, so as to adapt to the hot pressing treatment of non-woven fabrics of different widths. When the third hot pressing plate 16 and the second hot pressing plate 14 move back to back, the fifth heat conducting plate 20 outside the second electric heating tube 21 will slide in the moving groove 19, thereby filling the gaps between the second heat conducting plate 13 and the fourth heat conducting plate 17 and the second heat conducting plate 13 and the third heat conducting plate 15. Ensure that the non-woven fabrics maintain contact with the heat conducting plates at various locations during the movement. When adapting to the use of non-woven fabrics with wider sizes, the position of the second supporting component 5 can be adjusted by the first supporting component 3, such as Figure 1-Figure 3 As shown, the connecting rod 303 enables the two sliders 302 on the device to slide simultaneously, and the connecting line of the two sliders 302 always passes through the central axis of the device. After the sliders 302 slide in the guide rail 301, the feeding direction of the non-woven fabric can be changed, thereby adapting to the use of non-woven fabrics with wider sizes.

[0035] like Figure 1-Figure 4 and Figure 6-Figure 9 As shown, the second support assembly 5 on one side is used to unwind the nonwoven fabric, and the second support assembly 5 on the other side is used to rewind the nonwoven fabric. The support rod 504 is used to wind the nonwoven fabric. An external driving device (such as Figure 1 As shown), the support rod 504 is automatically reeled in. When reeling in, due to the resistance between the support rod 504 and the damping ring 505 used for unwinding, the non-woven fabric can be kept taut during the winding process. As the diameter of the non-woven fabric roll gradually increases, the connecting plate 503 will gradually slide in the first heat conducting plate 501 through the damping block 502. During this process, the third electric heating tube 23 gradually approaches the first heat conducting plate 501, so that the device can be preheated when unwinding the non-woven fabric. When reeling in the non-woven fabric, the temperature can be gradually reduced as the non-woven fabric is reeled in, thereby improving the production quality of the non-woven fabric. Fig. 9 As shown, when the non-woven fabric passes through the upper and lower groups of hot pressing components 22, the fourth hot pressing plate 2201 can be rotated by the rotating ring 2203 according to the feeding direction of the non-woven fabric, and the angle of the fourth hot pressing plate 2201 can be changed, so that the rotating wheel 2202 is perpendicular to the feeding direction of the non-woven fabric, so that the rotating wheel 2202 can press the non-woven fabric during the hot pressing process and can also rotate, so that the non-woven fabric remains flat, and the sealing cavity formed between the sealing pad 2204, the sealing ring 2205 and the rotating wheel 2202 can reset the rotating wheel 2202 after the rotating wheel 2202 is compressed. After the winding of the device is completed, the third connecting block 407 above the second connecting block 405 can be rotated through the hinge 408. When the third connecting block 407 rotates, it can resist the sliding rod 409. After being resisted, the sliding rod 409 will shrink to the inside of the second connecting block 405. At this time, the second spring 406 is compressed, and the card rod 403 slides inside the docking block 402 until the card rod 403 is completely moved to the inside of the docking block 402. At this time, under the action of the first spring 404, the docking block 402 will be pushed out, thereby realizing the function of automatic disengagement, and the second connecting block 405 can be reinstalled to the inside of the first connecting block 401 according to the above reverse steps.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
