Description

Technical Field

[0001] This invention belongs to the technical field of glass fiber cloth processing equipment, and specifically relates to a drying device for glass fiber cloth. Background Technology

[0002] In recent years, fiberglass cloth has been increasingly widely used in electronics, construction, aerospace and other fields due to its excellent properties such as high strength, acid and alkali resistance, and good insulation. The market's requirements for its product quality are also constantly increasing. Drying, as a key process in fiberglass cloth production, directly affects the product's moisture content, smoothness, and mechanical properties.

[0003] However, most existing drying devices adopt a drying box structure with a fixed layout of heating tubes. Multiple sets of heating tubes form a continuous drying zone to dry the fiberglass cloth in batches. The fixed drying distance between the heating tubes and the fiberglass cloth can easily lead to over-drying of thin cloth and incomplete drying of thick cloth. At the same time, the fixed distance and angle between the heating tubes can easily lead to poor heat distribution in the drying area and local high temperature, which can easily damage the cloth. Summary of the Invention

[0004] The purpose of this invention is to provide a drying device for glass fiber cloth, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A drying device for fiberglass cloth includes an adjustment mechanism, which includes a dryer body for drying the fiberglass cloth. The dryer body has a plurality of drying zones composed of heating tubes in its inner cavity. A plurality of back plates are provided on both sides of the drying zones composed of heating tubes. Each of the back plates is provided with a lifting component for adjusting the drying distance between the heating tubes and the fiberglass cloth. The spacing adjustment mechanism includes a lifting groove that runs through the upper part of several back plates. Each lifting groove has a lifting slide rod slidably installed in its inner cavity. Each lifting slide rod is equipped with a rotating component, which is used to adjust the angle of the heating tubes and thus change the distance between the heating tubes. Angle selection mechanism includes a knob that is movably mounted through the end of the lifting slide bar, and a horizontal push assembly is provided on the knob, which is used to move the dryer bodies closer together or further apart.

[0006] As a preferred embodiment of the glass fiber cloth drying device of the present invention, several of the lifting components include an electric push rod fixedly installed on one side of the back plate, a push-pull rod fixedly installed at the telescopic end of the electric push rod, the middle of the push-pull rod passing through the fixing parts at both ends of the heating tube and slidably connected to the heating tube, and a guide rod provided on the opposite side of the push-pull rod, the guide rod being movably connected through the fixing parts at both ends of the heating tube.

[0007] As a preferred embodiment of the glass fiber cloth drying device of the present invention, the rotating assembly includes a ratchet rotatably disposed at the end of the lifting slide rod away from the knob, a pawl is provided on one side of the ratchet, a support plate is provided on one side of the pawl that can flip the pawl, and a horizontal connecting rod is fixedly disposed at the lower part of the support plate, the horizontal connecting rod movably passing through the lifting slide rod.

[0008] As a preferred embodiment of the glass fiber cloth drying device of the present invention, a compression spring is elastically connected between the pawl and the support plate. The compression spring is used to reset the pawl after the ratchet pushes it to flip, thereby limiting the ratchet.

[0009] As a preferred embodiment of the glass fiber cloth drying device of the present invention, a spur gear is fixedly provided on one side of the ratchet and the guide rod. The spur gear is fixedly connected to the upper end of the guide rod, and a first rack is meshed on one side of the spur gear. The first rack is used to enable the spur gear to drive the guide rod to adjust the tilt angle.

[0010] As a preferred embodiment of the glass fiber cloth drying device of the present invention, the horizontal push assembly includes a second toothed plate meshing with the spur gear on the side away from the first rack. The second toothed plate has a vertical guide groove on the side wall of the knob. Two fixed round rods are fixedly installed at the upper and lower ends of the vertical guide groove. A horizontal sliding groove is provided on the outside of the two fixed round rods. Both horizontal sliding grooves are opened on the back plate.

[0011] As a preferred embodiment of the glass fiber cloth drying device of the present invention, a side plate is fixedly provided on the side of the second toothed plate away from the spur gear, and a side push rod is abutted on the outside of the side plate. An arc-shaped guide groove is provided on the outside of the side push rod, and the arc-shaped guide groove is movably provided through the back plate. The side push rod is fixedly connected to the knob.

[0012] As a preferred embodiment of the glass fiber cloth drying device of the present invention, the horizontal push assembly further includes a trapezoidal groove formed on the knob, and a trapezoidal limiting plate is inserted into the inner cavity of the trapezoidal groove. The trapezoidal limiting plate is fixedly set on the outer ring surface of the lifting slide rod.

[0013] As a preferred embodiment of the glass fiber cloth drying device of the present invention, the lower end of the second toothed plate is provided with a pawl and a support plate, just like the first toothed rack. The first toothed rack is also provided with a vertical guide groove, a fixed round rod, and a horizontal sliding groove at the knob end. The inner cavity of the vertical guide groove is slidably connected to the rotating shaft of the pawl, so that the pawl can push the horizontal connecting rod when the lifting slide rod moves.

[0014] As a preferred embodiment of the glass fiber cloth drying device of the present invention, the fixing parts at both ends of the heating tube are cylindrical, and the ends of the fixing parts of the heating tube abut against the surface of the spur gear away from the knob.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By adjusting the lifting assembly structure composed of electric push rod, push-pull rod and guide rod in the adjustment mechanism, the drying distance between the heating tube and the glass fiber cloth can be flexibly adjusted. The drying distance can be precisely adapted to glass fiber cloth of different thicknesses to avoid over-drying of thin cloth and incomplete drying of thick cloth.

[0016] 2. Through the ratchet and pawl mechanism of the spacing adjustment mechanism, the spur gear and the first rack working together, and the knob, the second toothed plate and the side push rod linkage mechanism of the angle selection mechanism, the angle and spacing of the heating tubes can be adjusted in both directions to optimize the heat distribution in the drying area, thereby solving the problem of local high temperature and reducing fabric damage.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1 Reference Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides a drying device for glass fiber cloth, which realizes the effect of changing the heat of the heating tubes 11 in different drying zones to prevent over-drying of the fiber cloth. It includes an adjustment mechanism, which includes a dryer body 10 for drying the fiber cloth. The inner cavity of the dryer body 10 is provided with a plurality of drying zones composed of heating tubes 11. A plurality of back plates 12 are provided on both sides of the drying zones composed of heating tubes 11. A lifting component 13 for adjusting the drying distance between the heating tubes 11 and the fiber cloth is provided on each of the back plates 12. The spacing adjustment mechanism includes a lifting groove 20 that runs through the upper part of several back plates 12. Each lifting groove 20 has a lifting slide rod 21 slidably installed in its inner cavity. Each lifting slide rod 21 is equipped with a rotating component 22. The rotating component 22 is used to adjust the angle of the heating tube 11 and thus change the distance between the heating tubes 11. Angle selection mechanism includes a knob 30 that is movably mounted through the end of the lifting slide bar 21. A horizontal push assembly 31 is provided on the knob 30. The horizontal push assembly 31 is used to move the distance between the dryer bodies 10 closer or further apart.

[0031] Specifically, the lifting assembly 13 can change the distance between the heating tube 11 and the fiber cloth, thereby better drying the fiber cloth according to different working conditions, thus preventing over-drying or unsatisfactory drying effect. At the same time, the horizontal pushing assembly 31 changes the meshing between the spur gear 226, the first rack 227, and the second toothed plate 311 in the rotating assembly 22, thereby changing the tilt angle of the guide rod 133 in the lifting assembly 13. This allows the heating tube 11 to move closer to the center or further away when adjusting its height, thereby changing the temperature of different areas and achieving a better drying effect.

[0032] Furthermore, several lifting components 13 include an electric push rod 131 fixedly installed on one side of the back plate 12. A push-pull rod 132 is fixedly installed at the telescopic end of the electric push rod 131. The middle part of the push-pull rod 132 passes through the fixing parts at both ends of the heating tube 11 and is slidably connected to the heating tube 11. A guide rod 133 is provided on the opposite side of the push-pull rod 132. The guide rod 133 is movably connected through the fixing parts at both ends of the heating tube 11.

[0033] In this device, the electric actuator 131 is an existing device, and its structural principle will not be elaborated here. Furthermore, the heating element 11 in this device is an independent unit, allowing for individual adjustment. It should be noted that the heating elements 11 are spaced one apart, and transverse grooves are provided on both the upper and lower parts of the back plate 12. Pin holes (such as those on the upper and lower parts of the back plate 12) are also provided on these grooves and on the upper and lower parts of the back plate 12. Figure 4 , Figure 5 As shown in the figure, the position of the back plate 12 can be adjusted, and different heating tubes 11 can be selected for raising and lowering.

[0034] In use, firstly, based on the thickness, humidity, and other working conditions of the fiberglass cloth to be dried, adjust the position of the back plate 12 using the transverse sliding grooves on the upper and lower parts of the back plate 12, and then fix the back plate 12 using the pin holes. This allows for the selection of the heating tube 11 whose height needs to be adjusted. Because the device uses a design of alternating heating tubes, the target heating tube 11 can be selected specifically. Next, activate the electric push rod 131 in the lifting assembly 13. The telescopic end of the electric push rod 131 drives the push-pull rod 132 in a linear motion. Since the middle of the push-pull rod 132 passes through the fixing parts at both ends of the heating tube 11 and is slidably connected to the heating tube 11, and the guide rod 133 is movably connected to the fixing parts at both ends of the heating tube 11, the movement of the push-pull rod 132 will drive the heating tube 11 to slide along the lifting slide rod 21 in the lifting groove 20 through the guiding action of the guide rod 133. This changes the drying distance between the heating tube 11 and the fiberglass cloth. It should be noted that when the distance is shortened, the drying heat is more concentrated, and when the distance is increased, the heat is more dispersed, thus avoiding the problem of over-drying or incomplete drying of the fiberglass cloth.

[0035] If further adjustment of the temperature distribution in different drying zones is required, the horizontal push assembly 31 can be operated via knob 30 to switch the meshing state between the second toothed plate 311 in the horizontal push assembly 31 and the spur gear 226 and first rack 227 in the rotating assembly 22. When the meshing relationship changes, it will drive the rotating assembly 22 to operate, thereby adjusting the tilt angle of the guide rod 133. After the tilt angle of the guide rod 133 changes, the heating tube 11 will shift laterally along the lifting slide rod 21 while adjusting its height via the lifting assembly 13, thereby adjusting the distance between the heating tubes 11. When the heating tube 11 moves closer to the center, the heating density and temperature in that area increase, and when it moves further away, the heating density and temperature decrease. Since the heating tube 11 in this device is an independent unit, its distance and angle can be adjusted individually. Combined with the position adjustment function of the back plate 12, it can flexibly adapt to the drying needs under different working conditions. Ultimately, through the synergistic effect of each mechanism, precise and efficient drying of the fiberglass cloth can be achieved.

[0036] Example 2 Reference Figure 4 - Figure 10 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a spacing adjustment mechanism for the glass fiber cloth drying device, solving the problem that a fixed distance between the heating tubes 11 is not conducive to adjustment according to different working conditions. It includes a rotating assembly 22 comprising a ratchet 221 rotatably disposed at the end of the lifting slide bar 21 away from the knob 30. A pawl 222 is provided on one side of the ratchet 221, and a support plate 223 capable of flipping the pawl 222 is provided on one side of the pawl 222. A horizontal connecting rod 224 is fixedly disposed at the lower part of the support plate 223. 224 The lifting slide bar 21 is movable through the pawl 222. A compression spring 225 is elastically connected between the pawl 222 and the support plate 223. The compression spring 225 is used to reset the pawl 222 after the ratchet 221 pushes it to flip, thereby limiting the ratchet 221. A spur gear 226 is fixedly installed on one side of the ratchet 221 and the spur gear 226 is fixedly connected to the upper end of the guide rod 133. A first rack 227 is meshed on one side of the spur gear 226. The first rack 227 is used to enable the spur gear 226 to drive the guide rod 133 to adjust the tilt angle.

[0037] Specifically, the unidirectional engagement of ratchet 221 and pawl 222 enables unidirectional self-locking after the tilt angle of guide rod 133 is adjusted, effectively preventing the guide rod 133 from shifting due to equipment vibration or the weight of the heating tube 11 after adjustment, thus ensuring the stability of the heating tube 11 spacing after adjustment.

[0038] In use, first, the position of the back plate 12 is adjusted and fixed. After selecting the target heating tube 11, the horizontal push assembly 31 is operated by the knob 30 to make the second toothed plate 311 mesh with the first rack 227 in the rotating assembly 22. Then, the heating tube 11 is pushed upward by the electric push rod 131, which in turn causes the heating tube 11 to drive the guide rod 133 to move upward as a whole. At this time, since the first rack 227 is meshed with the spur gear 226 and the spur gear 226 is fixedly connected to the upper end of the guide rod 133, the spur gear 226 can rotate and drive the guide rod 133 to rotate synchronously, thereby adjusting the tilt angle of the guide rod 133. When the spur gear 226 moves, it will drive the lifting slide 21, ratchet 221, pawl 222, and even the cross link 224 to move upward synchronously. While the spur gear 226 rotates, the ratchet 221, which is fixedly connected to it, rotates synchronously. When the ratchet 221 rotates in the target direction of angle adjustment, the teeth will squeeze the pawl 222, causing the pawl 222 to rotate around the connection point of the support plate 223. At this time, the compression spring 225 between the pawl 222 and the support plate 223 is compressed. When the tilt angle of the guide rod 133 is adjusted to the preset position and the first rack 227 is stopped from being pushed, the compression spring 225 will release its elastic potential energy, pushing the pawl 222 to reset, so that the pawl 222 can be re-engaged in the tooth gap of the ratchet 221, thereby achieving one-way limiting of the ratchet 221, and then locking the tilt angle of the guide rod 133 through the spur gear 226. After this, the electric push rod 131 in the lifting assembly 13 is activated. The electric push rod 131 drives the push-pull rod 132 to move. Under the inclined guidance of the guide rod 133, the heating tube 11 slides along the inner cavity of the guide rod 133, completing the adjustment of the drying distance between it and the fiber cloth. At the same time, the spacing of the heating tube 11 is controlled by the fixed angle of the guide rod 133.

[0039] Throughout the process, the one-way self-locking structure of ratchet 221 and pawl 222 can effectively resist the influence of external forces such as vibration during equipment operation and the weight of the heating tube 11 itself, prevent the guide rod 133 from deviating unexpectedly, and ensure the stability of the heating tube 11 after the spacing is adjusted. Combined with the independent adjustment characteristics of the heating tube 11, the adaptability of the device to different working conditions is further improved, ensuring the accuracy and reliability of the drying process.

[0040] Example 3 Reference Figure 4 - Figure 10This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an angle selection mechanism for the glass fiber cloth drying device, solving the problem that the heating tube 11 can only be adjusted in one direction. It includes a horizontal push assembly 31 comprising a second toothed plate 311 meshing with the spur gear 226 on the side away from the first rack 227. A vertical guide groove 312 is formed on the side wall of the second toothed plate 311 on the side of the knob 30. Two fixed round rods 313 are fixedly mounted at the upper and lower ends of the vertical guide groove 312. A horizontal sliding groove 314 is formed on the outside of each of the two fixed round rods 313. Both horizontal sliding grooves 314 are formed on the back plate 12. A side plate 315 is fixedly mounted on the side of the second toothed plate 311 away from the spur gear 226. A side push rod 316 abuts against the outside of each side plate 315. An arc-shaped guide groove 317 is formed on the outside of the side push rod 316. The arc-shaped guide groove 317 movably passes through... The side push rod 316 is fixedly connected to the knob 30 and is mounted on the back plate 12. The horizontal push assembly 31 also includes a trapezoidal groove 318 opened on the knob 30. A trapezoidal limiting plate 319 is inserted into the inner cavity of the trapezoidal groove 318. The trapezoidal limiting plate 319 is fixedly mounted on the outer ring surface of the lifting slide rod 21. The lower end of the second toothed plate 311 is provided with a pawl 222 and a support plate 223, just like the first toothed rack 227. The first toothed rack 227 is also provided with a vertical guide groove 312, a fixed round rod 313 and a horizontal sliding groove 314 at one end of the knob 30. The inner cavity of the vertical guide groove 312 is slidably connected to the rotating shaft of the pawl 222, so that the pawl 222 can push the horizontal connecting rod 224 when the lifting slide rod 21 moves. The fixing parts at both ends of the heating tube 11 are cylindrical, and the end of the fixing part of the heating tube 11 abuts against the surface of the spur gear 226 away from the knob 30.

[0041] Specifically, the meshing of the spur gear 226 with the second toothed plate 311 forms a bidirectional transmission structure with the first rack 227, breaking the limitation of single-direction adjustment. This allows the spur gear 226 to drive the guide rod 133 to achieve bidirectional angle rotation under the action of bidirectional driving force, thereby allowing the heating tube 11 to be adjusted to different orientations according to drying requirements.

[0042] In use, if it is necessary to adjust the forward angle of the heating tube 11 so that the heating tube 11 moves closer to the center, the knob 30 can be pulled outward to disengage the trapezoidal groove 318 from the trapezoidal limiting plate 319. Then, the knob 30 is rotated, which causes the knob 30 to drive the side push rod 316 to abut against the side plate 315 and push the second toothed plate 311. The second toothed plate 311 slides smoothly along the horizontal sliding groove 314 on the back plate 12 through the cooperation of the vertical guide groove 312 and the fixed round rod 313. This allows the second toothed plate 311 to maintain a meshing state with the spur gear 226 in the rotating assembly 22 and transmit driving force, which can drive the spur gear 226 to rotate forward. At this time, the trapezoidal groove 318 and the trapezoidal limiting plate 319 are aligned. Then, the knob 30 is turned back to allow the trapezoidal groove 318 and the trapezoidal limiting plate 319 to be inserted and limited.

[0043] Conversely, if it is necessary to adjust the heating tube 11 in the opposite direction to move it away from the other side, the knob 30 can be pulled outward to disengage the trapezoidal groove 318 from the trapezoidal limiting plate 319. Then, the knob 30 can be rotated, causing the knob 30 to drive the side push rod 316 to rotate in the arc-shaped guide groove 317. This causes the side push rod 316 to abut against the side plate 315 and push the first rack 227, which is fixed on the same side, to move towards the spur gear 226. When the first rack 227 moves towards the spur gear 226, the side plate 315 will push its lower end. The pawl 222 moves together with the support plate 223 and pushes the cross link 224 through the support plate 223. This causes the cross link 224 to push the pawl 222, which is already engaged and limited by the ratchet 221, away from the support plate 223. When the first rack 227 and the spur gear 226 mesh with each other, the trapezoidal groove 318 and the trapezoidal limiting plate 319 are aligned. Then, the knob 30 is turned back to make the trapezoidal groove 318 and the trapezoidal limiting plate 319 interlock and limit each other. Then, the heating tube 11 can be adjusted to different tilt angles through the steps of Embodiment 2.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
