Description

Technical Field

[0001] This invention relates to the textile field, and more particularly to a radio frequency drying device for textiles. Background Technology

[0002] In the process of dyeing and finishing fabrics, washing and drying are often involved. After washing, the fabric needs to be dried. Patent application number CN202122145032.9 discloses a textile drying box for cotton fabric production. However, this drying box has the following drawbacks in drying fabrics: 1) low drying efficiency; 2) inability to achieve uniform drying, resulting in poor drying effect; 3) after washing, some lint and other debris adhere to the fabric, and this lint will be carried along with the fabric into the drying process. The drying oven is used for drying. If the lint adhering to the fabric is not removed in time, it will affect the overall quality of the fabric. Furthermore, if this lint enters the air, it will pollute the environment, and if inhaled, it will affect human health. In the aforementioned patent, the fabric passes between the rollers and the squeeze rollers in the drying oven. This means that during the drying process, the lint is squeezed and adheres to the fabric more tightly, making it impossible to detach from the fabric during the drying process. As a result, this lint will gradually disperse during subsequent handling, worker processing, or sales. Summary of the Invention

[0007] Preferably, the guide-shaking mechanism includes a U-shaped seat fixed at both ends of the groove, one end of a spring fixed on the inner bottom surface of the U-shaped seat, the other end of the spring fixed on the bottom surface of the movable rod, a fourth guide roller rotatably connected between the two movable rods, a first set of limiting blocks fixed at the two top ends of the U-shaped seat, and a second set of limiting blocks fixed at the bottom end of the movable rod.

[0008] Preferably, the height of the third guide roller and the fabric outlet is lower than the height of the annular airbag, and the above three are in an inverted V shape.

[0009] Preferably, a pressing mechanism is provided on the side of the third guide roller away from the first support frame.

[0010] Preferably, the clamping mechanism includes a vertical rod fixed to a support platform, a horizontal rod fixed to the top of the vertical rod, a cylinder fixed to the horizontal rod, a telescopic rod of the cylinder passing through the horizontal rod, a pressure plate fixed to the bottom end of the telescopic rod, a pad provided below the pressure plate, and the pad fixed to the support platform.

[0011] Preferably, the two ends of the support tube are fixed to the front and rear inner walls of the radio frequency drying box, and the adjacent support tubes are staggered vertically. The support tube is hollow. The lower end of the upper support tube is connected to the upper end of the first connecting pipe, and the lower end of the first connecting pipe is connected to the first summing pipe. The left end of the first summing pipe passes through the radio frequency drying box and is connected to the left annular airbag.

The right end of the second summing pipe passes through the radio frequency drying box and is connected to the right annular airbag. A dust suction mechanism is provided in the groove.

[0012] Preferably, the dust collection mechanism includes several one-way air valves disposed on the groove bottom plate, and an adsorption plate is provided between the one-way air valves and the fourth guide roller.

[0013] Preferably, a first vacuum cleaner and a second vacuum cleaner are fixed on the radio frequency drying box. The first vacuum cleaner is fixed on the left outer side wall of the radio frequency drying box and is positioned above the fabric inlet. The second vacuum cleaner is fixed on the right outer side wall of the radio frequency drying box and is positioned below the fabric outlet.

[0014] (III) Beneficial Effects

[0015] 1. This invention sets the drying box as a radio frequency drying box, which not only improves the drying efficiency of the fabric, but also makes the fabric heat evenly, thereby improving the drying effect. In addition, through the setting of the cloth guiding and shaking mechanism and the ring airbag, some lint and other debris adhering to the fabric can be removed in the radio frequency drying box, so that they are removed from the fabric, improving the quality of the fabric, while not polluting the environment and protecting human health.

[0016] 2. The present invention sets the guide fabric-shaking mechanism in the groove and sets it to consist of a U-shaped seat, a spring, a movable rod and a fourth guide fabric roller. As the air pump continuously pumps air into the annular airbag, the excess fabric is gradually released. This process of continuously releasing excess fabric is also a process of continuously shaking the fabric, causing lint and other debris adhering to the fabric to detach from the fabric. At the same time, it is also a process of continuously accelerating the heat dissipation of the fabric, which greatly accelerates the drying rate of the fabric. In addition, during the process of continuously releasing excess fabric, the position of the fabric is also constantly moving and adjusting. In this way, the part of the fabric that was originally attached to the fourth guide fabric roller and the fabric support cylinder will change position, further improving the drying effect of the fabric.

[0017] 3. The cloth guiding and shaking mechanism of the present invention can not only shake the cloth, but also guide the cloth. The cloth is tangent to the cloth support cylinder, and a channel connected to the groove is left between the cloth support cylinder and the fourth cloth guiding roller. Compared with ordinary cloth guiding rollers, this structure not only provides good support for the cloth and prevents the cloth from deforming, but also accelerates the heat dissipation of the cloth and ensures the drying effect.

[0018] 4. The present invention can effectively limit the fabric by setting two clamping mechanisms, limiting the release and position adjustment of the fabric excess to the required radio frequency drying device section, and also providing good protection for the fabric.

[0019] 5. The present invention effectively adsorbs and collects the lint generated by this part of the fabric through the arrangement of the first connecting pipe, the first collecting pipe, the second connecting pipe, the second collecting pipe, the one-way air valve and the adsorption plate. Moreover, the structure cleverly utilizes the process of the air pump evacuating the annular airbag, adsorbing the lint while evacuating the air, without the need for additional dust collection equipment. When the air pump inflates the annular airbag, due to the setting of the one-way air valve, the airflow will not leak from the fabric support cylinder into the groove, so it will not affect the air pump from fully inflating the annular airbag.

[0020] 6. The present invention uses a first vacuum cleaner and a second vacuum cleaner to absorb the lint that is shaken off inside the radio frequency drying box, and also facilitates the discharge of moisture inside the radio frequency drying box. The first vacuum cleaner and the second vacuum cleaner are arranged one above the other, which facilitates the removal of lint and moisture from the top and bottom of the fabric.

Detailed Implementation

[0029] The following will refer to the appendices in the embodiments of the present invention. Figure 1-7 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: a radio frequency (RF) drying device for textiles, comprising a support platform 1, on which an RF drying chamber 2 is fixed. Fabric inlets 3 and fabric outlets 4 are respectively opened on the left and right side plates of the RF drying chamber 2. A first guide roller 5 and a second guide roller 6 are provided inside the RF drying chamber 2. The first guide roller 5 is located near the fabric inlet 3, and the second guide roller 6 is located near the fabric outlet 4. A plurality of fabric support cylinders 7 are provided between the first guide roller 5 and the second guide roller 6. A groove 8 is opened at one end of the fabric support cylinder 7, and a fabric guiding-shaking mechanism 9 is provided within the groove 8. First support frames 10 are provided on both the left and right sides of the RF drying chamber 2. An annular airbag 11 is fixed on the frame 10. The annular airbag 11 is equipped with an inflation pump 12 and a de-inflation pump 13. A second support frame 14 is located on the side of the first support frame 10 away from the radio frequency drying chamber 2. A third guide roller 15 is rotatably connected to the second support frame 14. During operation, the cleaned fabric is guided to the radio frequency drying device for drying. First, the fabric passes under the third guide roller 15 on the left side, then passes over the annular airbag 11, at which point the annular airbag 11 is inflated. Then, it enters the radio frequency drying chamber 2 through the fabric inlet 3. Inside the radio frequency drying chamber 2, the fabric first passes under the first guide roller 5, wherein the first guide roller 5 is connected to the radio frequency drying device. The inner wall of the drying chamber 2 is rotated and connected. Then, starting from the left, the cloth guide-shaking mechanism 9 passes sequentially around each cloth support cylinder 7, and then passes under the second cloth guide roller 6. At this point, the cloth stops moving. Then, the two suction pumps 13 start, sucking air from the annular airbag 11. This suction process relaxes the originally taut cloth. This relaxation causes the cloth guide-shaking mechanism 9 to shake the cloth inside the RF drying chamber 2. This shaking process removes lint and other debris adhering to the cloth, further cleaning the cloth and improving its quality. Additionally, this shaking... The drying process also accelerates heat dissipation from the fabric, further improving drying efficiency. The size of the annular airbag 11 and the air extraction rate are set according to actual needs and desired effects. After the air extraction process of the annular airbag 11 is completed, the air extraction pump 13 stops operating, and the two inflation pumps 12 start operating to inflate the annular airbag 11 until it is fully inflated, returning to its previous state. This process tensions the fabric until it returns to its previous tension. Afterward, the dried fabric in the RF drying chamber 2 is exported from the RF drying chamber 2, while new fabric to be dried is introduced into the RF drying chamber 2, and this cycle repeats. The RF drying chamber 2 is existing technology, so its specific structure will not be described in detail here.This invention sets the drying chamber as a radio frequency drying chamber 2, which not only improves the drying efficiency of the fabric, but also makes the fabric heat evenly, thereby improving the drying effect. In addition, through the setting of the cloth guiding and shaking mechanism 9 and the annular airbag 11, this invention can remove some lint and other debris adhering to the fabric in the radio frequency drying chamber 2, so that they are removed from the fabric, improving the quality of the fabric, while not polluting the environment and protecting human health.

[0031] The fabric guiding and shaking mechanism 9 includes a U-shaped seat 16 fixed at both ends of the groove 8. One end of a spring 17 is fixed on the inner bottom surface of the U-shaped seat 16, and the other end of the spring 17 is fixed on the bottom surface of the movable rod 18. A fourth fabric guiding roller 19 is rotatably connected between the two movable rods 18. A first limiting block group 20 is fixed at the two top ends of the U-shaped seat 16, and a second limiting block group 21 is fixed at the bottom end of the movable rod 18. The specific working principle of the fabric guiding and shaking mechanism 9 is as follows: When the annular airbag 11 is inflated, the fabric is fully tensioned, and the spring 17 is fully compressed. When the air pump 13 starts to pump air from the annular airbag 11, the annular airbag 11 gradually collapses, causing the originally tensioned fabric to gradually loosen. Once the fabric loosens, the originally compressed spring 17 will rebound. This rebound process of the spring 17... This causes the movable rod 18 to spring upward, which in turn causes the fourth guide roller 19, which is in contact with the fabric, to move upward. This creates a shaking process on the fabric, shaking off any lint or other debris adhering to it. This shaking process also accelerates the drying rate of the fabric. As the annular airbag 11 is continuously pumped out, the excess fabric is gradually released. This process of releasing excess fabric is also a process of continuously shaking the fabric, causing lint and other debris to detach. It also accelerates the heat dissipation of the fabric, greatly speeding up the drying rate. In addition, during this process of releasing excess fabric, the position of the fabric is constantly moving and adjusting. This causes the portion of the fabric that was originally attached to the fourth guide roller 19 and the fabric support cylinder 7 to change position, further improving the drying effect of the fabric. The cloth guiding and shaking mechanism 9 not only shakes the cloth but also guides it. The cloth is tangent to the cloth support cylinder 7, and a channel connected to the groove 8 is left between the cloth support cylinder 7 and the fourth cloth guide roller 19. Compared with ordinary cloth guide rollers, this structure not only provides good support for the cloth and prevents it from deforming, but also accelerates the heat dissipation of the cloth and ensures the drying effect.

[0032] The height of the third guide roller 15 and the fabric outlet 4 is lower than the height of the annular airbag 11, and the above three are in an inverted V shape. This setting can ensure that the remaining amount of fabric can be released when the annular airbag 11 is pumped out.

[0033] The third guide roller 15 is provided with a pressing mechanism 22 on the side away from the first support frame 10. Since the dyeing and finishing of the fabric is a long production line from the fabric unwinding mechanism at the source to the fabric winding mechanism at the end, the setting of two pressing mechanisms 22 can play a good role in limiting the fabric, and the release and position adjustment of the fabric allowance are limited to the required radio frequency drying device section.

[0034] The clamping mechanism 22 includes a vertical rod 23 fixed on the support platform 1, a horizontal rod 24 fixed to the top of the vertical rod 23, a cylinder 25 fixed on the horizontal rod 24, a telescopic rod 26 of the cylinder 25 passing through the horizontal rod 24, and a pressure plate 27 fixed to the bottom end of the telescopic rod 24. A pad 28 is provided below the pressure plate 27 and is fixed on the support platform 1. This is the specific structure of the clamping mechanism 22. Before the air pump 13 starts, the cylinder 25 starts first, and the telescopic rod 26 extends. The pressure plate 27 is driven downward until the fabric is clamped between the pressure plate 27 and the pad 28. Before the fabric is clamped, the distance between the bottom surface of the fabric and the top surface of the pad 28 is 1mm-2mm. This distance will not cause friction between the fabric and the pad 28 during the fabric's forward movement, and it will not affect the clamping mechanism 22 from clamping the fabric. If the distance between the fabric and the pad 28 is too large before clamping, it will cause great pulling on the fabric, which may damage the fabric.

[0035] The two ends of the support cylinder 7 are fixed to the front and rear inner walls of the radio frequency drying chamber 2, and adjacent support cylinders 7 are arranged in an alternating vertical arrangement. The support cylinder 7 is hollow. The lower end of the upper support cylinder 7 is connected to the upper end of the first connecting pipe 29, and the lower end of the first connecting pipe 29 is connected to the first converging pipe 30. The left end of the first converging pipe 30 passes through the radio frequency drying chamber 2 and is connected to the left annular airbag 11. The upper end of the lower support cylinder 7 is connected to the lower end of the second connecting pipe 31, and the upper end of the second connecting pipe 31 is connected to the second converging pipe 32. The right end of the second converging pipe 32 passes through the radio frequency drying chamber 2 and is connected to the right annular airbag 11. A dust suction mechanism 33 is provided in the groove 8. The dust suction mechanism 33 includes several one-way air valves 34 set on the bottom plate of the groove 8, and the one-way air valves 34 and the fourth guide cloth. An adsorption plate 35 is provided between the rollers 19. The airflow direction of the one-way valve 34 can only flow from the groove 8 to the fabric support cylinder 7. The specific working principle is as follows: When the air pump 13 evacuates the annular airbag 11, the air pressure in the fabric support cylinder 7 will drop. At this time, the one-way valve 34 will be opened, which will act as an air suction device, adsorbing the lint generated by the shaking of the fabric onto the adsorption plate 35 for collection. Because the lint generated by the shaking of the fabric part corresponding to the groove 8 is difficult to expel due to the relatively closed space, these lints are easy to re-adhere to the fabric. Therefore, this structure effectively adsorbs and collects the lint generated by this part of the fabric. Moreover, this structure cleverly utilizes the process of the air pump 13 evacuating the annular airbag 11, adsorbing lint while evacuating air, without the need for additional dust collection equipment. When the air pump 12 inflates the annular airbag 11, due to the setting of the one-way valve 34, the airflow will not leak from the fabric support cylinder 7 to the groove 8, so it will not affect the air pump 12 from fully inflating the annular airbag 11.

[0036] A first vacuum cleaner 36 and a second vacuum cleaner 37 are fixed on the RF drying box 2. The first vacuum cleaner 36 is fixed on the left outer wall of the RF drying box 2 and is positioned above the fabric inlet 3. The second vacuum cleaner 37 is fixed on the right outer wall of the RF drying box 2 and is positioned below the fabric outlet 4. The arrangement of the first vacuum cleaner 36 and the second vacuum cleaner 37 is designed to absorb the lint that is shaken off inside the RF drying box 2 and to facilitate the removal of moisture from inside the RF drying box 2. The first vacuum cleaner 36 and the second vacuum cleaner 37 are positioned one above the other to facilitate the removal of lint and moisture from the top and bottom of the fabric.

[0037] Working principle: During operation, the cleaned fabric is guided to the radio frequency drying device of this invention for drying. First, the fabric passes under the third guide roller 15 on the left side, and then passes over the annular airbag 11, which is inflated at this time. Then, it enters the radio frequency drying chamber 2 through the fabric inlet 3. Inside the radio frequency drying chamber 2, the fabric first passes under the first guide roller 5, which is rotatably connected to the inner wall of the radio frequency drying chamber 2. Then, it passes sequentially from the left to the right, passing over the guide-shaking mechanism 9 on each support cylinder 7, and then passes under the second guide roller 6. At this time, the fabric stops moving. Then, the pressing mechanism 22 starts to press the fabric. After the fabric is pressed, the two suction pumps 13 start to evacuate the annular airbag 11. As the annular airbag 11 gradually collapses, the originally taut fabric gradually relaxes. Once the fabric relaxes, the originally compressed spring 17 will rebound. The rebound of spring 17 causes the movable rod 18 to bounce upwards, which in turn causes the fourth guide roller 19, which is in contact with the fabric, to bounce upwards. This creates a shaking effect on the fabric, shaking off any lint or other debris adhering to it. This shaking process also accelerates the drying rate of the fabric. As the annular airbag 11 is continuously pumped out, the excess fabric is gradually released. This process of releasing excess fabric is also a process of continuously shaking the fabric, causing lint and other debris to detach. It also accelerates the heat dissipation of the fabric, greatly speeding up the drying rate. In addition, during this process of releasing excess fabric, the position of the fabric is constantly moving and adjusting. This causes the portion of the fabric that was originally attached to the fourth guide roller 19 and the fabric support cylinder 7 to change position, further improving the drying effect of the fabric.The fabric guiding and shaking mechanism 9 not only shakes the fabric but also guides it. The fabric is tangent to the support cylinder 7, and a channel connecting to the groove 8 is provided between the support cylinder 7 and the fourth guide roller 19. Compared to ordinary guide rollers, this structure not only provides excellent support for the fabric, preventing deformation, but also accelerates heat dissipation and ensures effective drying. When the suction pump 13 pumps air from the annular airbag 11, the air pressure inside the support cylinder 7 decreases, opening the one-way valve 34 to draw in air. This collects the lint generated by the fabric shaking onto the suction plate 35. Because the lint generated by the shaking of the fabric corresponding to the groove 8 is difficult to expel due to the relatively enclosed space, it easily re-adheres onto the fabric. Therefore, this structure effectively manages the lint generated by the shaking of this part of the fabric. The structure cleverly utilizes the process of the air pump 13 evacuating the annular airbag 11 while simultaneously evacuating and absorbing the lint. After evacuating the annular airbag 11, the air pump 13 stops operating, and the two inflation pumps 12 start operating to inflate the annular airbag 11 until it is fully inflated, just like before it was evacuated. When the inflation pump 12 inflates the annular airbag 11, due to the one-way valve 34, the airflow will not leak from the fabric support cylinder 7 into the groove 8, so it will not affect the inflation pump 12 from fully inflating the annular airbag 11. This inflation process tensions the fabric until it returns to its previous tensioned state. Afterward, the dried fabric in the RF drying chamber 2 is exported from the RF drying chamber 2, while new fabric to be dried is guided into the RF drying chamber 2, and so on.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
