Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a high-efficiency drying and hot pressing molding machine for nonwoven fabrics. Background Technology

[0002] Traditional nonwoven fabrics require manual fixing and handling during the hot pressing process, which may cause workers to be burned by the hot press plate.

[0003] To address the aforementioned issues, patent document CN216550980U discloses a nonwoven fabric thermoforming device, comprising a base; symmetrical support plates are fixedly mounted at both ends of the top of the base, a fixing plate is fixedly mounted on the top of the support plates, a thermoforming plate is fixedly mounted on the bottom of the mounting plate, a sliding groove is symmetrically fixedly mounted at one end of the top of the base below the thermoforming plate, a slider slides within the sliding groove, a placement plate is fixedly mounted on the top of the slider extending out of the sliding groove, limiting mechanisms are symmetrically fixedly mounted at both ends of the top of the placement plate, and a connecting mechanism is fixedly mounted between the placement plate at one end of the sliding groove and the base. This nonwoven fabric thermoforming device avoids manual placement and fixing of the nonwoven fabric and removal of the thermoformed nonwoven fabric from below the thermoforming plate, thereby preventing burns caused by the heat generated by the thermoforming plate.

[0004] Based on the above search and combined with existing technology, it was found that although existing nonwoven fabric hot pressing molding equipment can reduce the probability of workers being burned by the heat of the hot pressing plate, it requires workers to push and pull the plate during use, which increases the operation steps, increases the workload of workers, and relatively reduces the molding efficiency. Therefore, there is a need for a nonwoven fabric high-efficiency drying hot pressing molding machine. Utility Model Content

[0012] Preferably, a third shaft is rotatably connected to the front end of the first connecting rod near the placement plate, and one end of the third shaft also extends into the second slide groove, with the third shaft and the second slide groove having a clearance fit.

[0015] Preferably, a pressing mechanism is also installed on the hot press plate. The pressing mechanism includes a pressing plate, a second spring and a guide rod. The upper end of the pressing plate is fixed to the lower end of the guide rod and the lower end of the second spring. The upper end of the guide rod slides through the top of the hot press plate and is integrally formed with a limit block. The bottom of the limit block abuts against the top surface of the hot press plate.

[0016] The second spring is movably sleeved on the guide rod, and the upper end of the second spring is fixed to the top of the hot press plate.

[0017] Preferably, the second link includes:

[0018] The movable sleeve has two mirror images of each other, and each of the two movable sleeves has a socket at the end that is close to the other.

[0019] The connecting rod has two ends that are slidably inserted into the insertion holes of two movable sleeve rods;

[0020] The first spring is also provided in two and is located in the two insertion holes respectively. The two ends of the two first springs are respectively fixed to one end of the connecting rod and the inner wall of the insertion hole.

[0021] The first shaft is rotatably inserted into the upper movable sleeve, and the end of the first shaft is rotatably connected to the top side wall of the hot press plate.

[0027] In summary, the technical effects and advantages of this utility model are as follows:

[0028] This invention, through the linkage mechanism, allows workers to simply place and remove the nonwoven fabric, eliminating the need for pushing and pulling the placement plate. This not only reduces labor intensity and makes the process more convenient, but also saves loading and unloading time by simultaneously performing the pushing and pulling of the placement plate and the lifting and lowering of the hot press plate, thus improving the efficiency of nonwoven fabric hot pressing. By making the second connecting rod a telescopic rod, it can be used in conjunction with the clamping mechanism. When the clamping mechanism presses the placement plate, the two movable sleeve rods gradually approach each other, overcoming the elastic force of the first spring. This allows the hot press plate to continue pressing smoothly down after the placement plate is fixed, completing the hot pressing operation. By setting up a slide rail and a limiting plate, workers can also position the end of the placed nonwoven fabric using the limiting plate, ensuring that the end of the nonwoven fabric is always in the same position, improving loading accuracy. Furthermore, the position of the limiting plate can be adjusted to adapt to different loading position requirements, making it more flexible to use. By setting up a drying chamber, the residual heat generated by the hot press plate can be utilized to quickly dry the non-woven fabric to be hot-pressed, removing moisture or solvents from the non-woven fabric, ensuring uniform drying of the material, and facilitating subsequent hot-pressing operations. This makes the hot press machine more versatile and energy-efficient. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0038] Example: Reference Figures 1-6 The nonwoven fabric high-efficiency drying hot pressing molding machine shown includes a machine body 1, a placement plate 2 that is horizontally slidably connected to the platform of the machine body 1, a hydraulic cylinder 3 fixed to the top of the machine body 1, and a hot pressing plate 4 fixed to the lower end of the piston rod of the hydraulic cylinder 3.

[0039] A linkage mechanism 5 is provided between the hot press plate 4 and the placement plate 2 for transmission. The linkage mechanism 5 includes:

[0040] The first link 51 is horizontally set and one end is fixed to the rear side of the placement plate 2;

[0041] The second connecting rod 52 has its upper end inclined toward the front of the machine body 1 and its lower end inclined toward the rear of the machine body 1. The upper end of the second connecting rod 52 is rotatably connected to the rear of the hot press plate 4, and the lower end of the second connecting rod 52 is rotatably connected to the end of the first connecting rod 51 away from the placement plate 2 through the second shaft 53.

[0042] The side wall of the machine body 1 is provided with a second slide groove 13, and one end of the second shaft 53 extends into the second slide groove 13 and is in clearance fit with the second slide groove 13.

[0043] Based on the above structure, in the state where the hot press plate 4 is not pressed down (e.g.) Figure 1As shown, the placement plate 2 is in an extended state. When the hot press plate 4 presses down, it drives the upper end of the second connecting rod 52 to press down synchronously, and drives the lower end of the second connecting rod 52 to drive the rear end of the first connecting rod 51 to move backward through the second shaft 53. This causes the placement plate 2 to move onto the platform of the machine body 1. After it moves into place, the hot press plate 4 presses down to hot press the nonwoven fabric. After forming, the hot press plate 4 moves up, and the second connecting rod 52 drives the first connecting rod 51 to move in the opposite direction, so that the placement plate 2 is reset and extends out of the platform of the machine body 1. This allows the operator to only place and remove the nonwoven fabric without having to push and pull the placement plate 2. This not only reduces the labor intensity of the operator and makes it more convenient to use, but also saves loading and unloading time by performing the pushing and pulling action of the placement plate 2 and the lifting action of the hot press plate 4 at the same time, thereby improving the efficiency of nonwoven fabric hot pressing.

[0044] Furthermore, a third shaft 54 ​​is rotatably connected to the front end of the first connecting rod 51 near the placement plate 2. One end of the third shaft 54 ​​also extends into the second slide groove 13, and the third shaft 54 ​​and the second slide groove 13 are in clearance fit.

[0045] An opening is formed on the rear side of the second slide groove 13, and a guide flare 131 is formed at the opening of the second slide groove 13.

[0046] The front end of the first connecting rod 51 has an integrally formed connecting fin plate 511. The connecting fin plate 511 abuts against the upper surface of the placement plate 2, and the connecting fin plate 511 is fixed to the placement plate 2 by bolts.

[0047] The third shaft 54 ​​makes the horizontal movement of the first connecting rod 51 more stable and reliable. At the same time, the guide flare 131 makes it easier for the second shaft 53 to enter the second slide groove 13 during the horizontal forward movement, thus preventing the first connecting rod 51 from failing to reset due to slight displacement after the second shaft 53 leaves the second slide groove 13.

[0048] Furthermore, a pressing mechanism 6 is also installed on the hot press plate 4. The pressing mechanism 6 includes a pressing plate 61, a second spring 62 and a guide rod 63. The upper end of the pressing plate 61 is fixed to the lower end of the guide rod 63 and the lower end of the second spring 62. The upper end of the guide rod 63 slides through the top of the hot press plate 4 and is integrally formed with a limiting block 631. The bottom of the limiting block 631 abuts against the top surface of the hot press plate 4.

[0049] The second spring 62 is movably sleeved on the guide rod 63, and the upper end of the second spring 62 is fixed to the top of the hot press plate 4.

[0050] With the setting of the pressing mechanism 6, when the hot press plate 4 is pressed down, it also drives the pressing mechanism 6 to descend synchronously. The pressing plate 61 first contacts the upper end of the placement plate 2 and presses the placement plate 2 (or the non-woven fabric edge on the placement plate 2) during the continuous pressing process. Specifically, when the hot press plate 4 continues to press down, it will compress the second spring 62, so that the second spring 62 continuously applies pressure to the pressing plate 61, thereby pressing the placement plate 2 and making the placement plate 2 more stable during the hot pressing process.

[0051] Furthermore, the second link 52 includes:

[0052] There are two movable sleeve rods 521 arranged in a mirror image, and each of the two movable sleeve rods 521 has a socket at the end that is close to each other.

[0053] Connecting rod 522, with both ends of the connecting rod 522 slidably inserted into the insertion holes of two movable sleeve rods 521;

[0054] Two first springs 523 are provided and located in two insertion holes respectively. The two ends of the two first springs 523 are respectively fixed to one end of the connecting rod 522 and the inner wall of the insertion hole.

[0055] The first shaft 524 is rotatably inserted into the upper movable sleeve 521, and the end of the first shaft 524 is rotatably connected to the top side wall of the hot press plate 4.

[0056] The lower movable sleeve 521 is rotatably sleeved on the second shaft 53.

[0057] By setting the second connecting rod 52 as a telescopic rod, it can be used in conjunction with the pressing mechanism 6. When the pressing mechanism 6 presses the placement plate 2, the two movable sleeve rods 521 gradually approach each other against the elastic force of the first spring 523, so that after the placement plate 2 is fixed, the hot press plate 4 can still be pressed down smoothly to complete the hot pressing molding operation.

[0058] Furthermore, rollers 21 are rotatably connected to both sides of the placement plate 2, and first grooves 12 are opened on both sides of the machine body 1, with the rollers 21 rolling and embedded in the first grooves 12.

[0059] Furthermore, two parallel slide rails 7 extending back and forth are fixed to the upper end of the placement plate 2, and the slide rails 7 are provided with scales 71;

[0060] Two slide rails 7 are slidably connected to a limiting plate 8. A fastening bolt 81 is screwed onto the limiting plate 8. The lower end of the fastening bolt 81 abuts against the upper surface of the slide rail 7. The limiting plate 8 and the slide rail 7 are perpendicular to each other on the horizontal plane.

[0061] By setting the slide rail 7 and the limiting plate 8, the operator can also use the limiting plate 8 to position the end of the placed non-woven fabric, so that the end of the non-woven fabric is always in the same position, improving the feeding accuracy. At the same time, the position of the limiting plate 8 can be adjusted to adapt to different feeding position positioning requirements, making it more flexible to use.

[0062] Furthermore, a drying chamber 11 is also provided at the lower part of the machine body 1. The opening of the drying chamber 11 faces one side of the machine body 1. A sealing door that closes the opening of the drying chamber 11 is hinged to one side of the machine body 1. The residual heat generated by the hot press plate 4 is transported to the drying chamber 11 through the pipeline.

[0063] By setting up the drying chamber 11, the residual heat generated by the hot press plate 4 can be utilized to quickly dry the non-woven fabric to be hot-pressed, remove moisture or solvent from the non-woven fabric, ensure uniform drying of the material, facilitate subsequent hot pressing operations, make the hot pressing machine more versatile, and achieve energy-saving effects.

[0064] The working principle of this utility model is as follows: During daily use, when the hot press plate 4 is not pressed down, the placement plate 2 is in an extended state. When the hot press plate 4 is pressed down, it drives the upper end of the second connecting rod 52 and the pressing mechanism 6 to press down synchronously, and drives the lower end of the second connecting rod 52 to drive the rear end of the first connecting rod 51 to move backward through the second shaft 53, thereby causing the placement plate 2 to move onto the platform of the machine body 1. After moving into position, the pressing plate 61 first contacts the upper end of the placement plate 2. When the hot press plate 4 continues to press down, it will compress the second spring 62, so that the second spring 62 continuously applies pressure to the pressing plate 61, thereby pressing the placement plate 2. The second connecting rod 52 can cooperate with... The pressing mechanism 6 is used to ensure that the hot press plate 4 can still press down smoothly. Then, the hot press plate 4 presses down to heat-press the non-woven fabric. After the forming is completed, the hot press plate 4 moves up, thereby using the second connecting rod 52 to drive the first connecting rod 51 to move in the opposite direction, so that the placement plate 2 is reset and extends out of the platform of the machine body 1. This allows the workers to only place and take out the non-woven fabric without having to push and pull the placement plate 2. This not only reduces the labor intensity of the workers and makes it more convenient to use, but also saves loading and unloading time by performing the pushing and pulling action of the placement plate 2 and the lifting action of the hot press plate 4 at the same time, thereby improving the efficiency of non-woven fabric heat pressing.

The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent.
