[0017] The present invention is provided with a preheating and solidifying device, that is, the hot air inside the drying tower body can enter the first heating box and the second heating box through the fan and the transmission pipe, so as to preheat the glass fiber cloth, make the coating initially solidified, and avoid the occurrence of subsequent drying flow phenomenon. In conjunction with the transmission of the connecting belt, the transmission roller and the cylinder, the first heating box and the second heating box can be moved laterally in opposite directions to enhance the preheating efficiency. Secondly, during the reciprocating transverse preheating activity, the horizontal plate arranged inside the scraping component will be driven, so that the horizontal plate can drive the transmission frame. In this way, in conjunction with the transmission groove and the connecting shaft, the pressing plate can press down the moving frame to realize the reciprocating scraping and leveling activity of the scraping strip on the glass fiber cloth, thereby achieving the advantages of preheating and solidifying the glass fiber cloth while assisting in the scraping and leveling of the outer coating of the glass fiber cloth.

[0018] The setting of the preheating component, that is, the two heat-conducting hoses connected to the lower end of the transmission pipe, can transmit hot air into the first heating box and the second heating box respectively, so as to assist in the initial curing of the outer coating of the glass fiber cloth.

[0035] The first support plate 1 and the second support plate 2 are both provided with openings at their upper ends to facilitate the stable feeding, discharging and drying of the glass fiber cloth.

[0036] Specifically, the glass fiber cloth will be fed through the guide roller 4 and the first auxiliary roller 5 arranged on the outer side of the first support plate 1 to achieve the feeding coordination of the glass fiber cloth, so that the glass fiber cloth is pre-penetrated into the drying tower body 11, and the upper conveying roller 9 and the lower conveying roller 10 arranged between the first support plate 1 and the second support plate 2 cooperate to make the glass fiber cloth present an S-shaped multi-stage winding transmission state.

[0037] See also Figure 2 The preheating and solidifying device 13 in this embodiment includes a preheating box 131 installed at the upper left end of the first support plate 1 and can be used for preheating processing of the glass fiber cloth, and the left and right sides of the lower end of the preheating box 131 are opened, a fan 132 is arranged on the right side of the upper end of the preheating box 131 and connected to the outer side of the drying tower body 11, and a transmission pipe 133 is connected to the air outlet end of the fan 132 and penetrates downward into the preheating box 131. In this way, the heat inside the drying tower body 11 can be introduced into the preheating box 131 to preheat and dry the glass fiber cloth. A preheating component 134 is arranged in the preheating box 131 and connected to the lower end of the transmission pipe 133, a supporting roller 135 rotatably connected to the left side of the preheating box 131 to realize the lateral transmission of the glass fiber cloth, a scraping component 136 is installed at the lower left end of the preheating box 131, and a collecting component 137 is installed at the bottom of the left side of the preheating box 131 and is opposite to the scraping component 136.

[0038] See also Figure 3-5 The preheating assembly 134 in this embodiment includes two heat-conducting hoses 1341 connected to the lower end of the transmission pipe 133, a first heating box 1342 connected to the lower end of one side of the heat-conducting hose 1341 and slidably connected to the inside of the preheating box 131, and a rectangular channel is provided in the middle of the first heating box 1342 for conveying the glass fiber cloth, and exhaust holes 1343 are symmetrically provided on the upper and lower sides of the first heating box 1342, and there is a gap between the upper and lower first heating boxes 1342, which are installed at the front and rear ends of the first heating box 1342. A spring 1344 built into the side wall of the preheating box 131 for elastic reset, a connecting belt 1345 connected to the lower end of the first heating box 1342 for pulling the lateral transmission, a transmission roller 1346 connected to the outer side of the connecting belt 1345 to enable the connecting belt 1345 to achieve stable lateral transmission, a secondary heat structure 14 connected to the other side of the connecting belt 1345 to enhance the preheating effect of the glass fiber cloth, a cylinder 1347 connected to the lower end of the secondary heat structure 14, and the secondary heat structure 14 includes a symmetrical installation on the first heating box 1342 The connecting shell 141 on the right side, the three-way pipe 142 installed inside the rear side of the connecting shell 141 and connected to the lower end of the heat-conducting hose 1341 on the other side, the butt-joint pipe 143 symmetrically installed at the upper and lower ends of the three-way pipe 142 for transmission on both sides, the support rods 144 symmetrically installed on the left and right sides of the butt-joint pipe 143, and the combination of the upper and lower butt-joint pipes 143 can be achieved through the support rods 144 on both sides, and the compression springs 145 are correspondingly arranged at the outer ends of the support rods 144 on both sides, and the upper and lower ends of the compression springs 145 are connected to the upper and lower butt-joint pipes 143. Correspondingly, a second heating box 146 is movably embedded in the upper and lower volumes of the connecting shell 141 and connected to the inlet ends of the butt tubes 143 on both sides, and there is a spacing between the second heating boxes 146 on both sides, and heat dissipation holes are opened on the opposite sides of the second heating boxes 146. A support bar 147 is laterally fixedly connected to the right side of the preheating box 131 and connected to the inside of the connecting shell 141, and the support bar 147 is symmetrically arranged as a whole, so as to assist in supporting the connecting shell 141 as a whole. The lower end of the connecting shell 141 is connected to the cylinder 1347.

[0039] Among them, the first heating box 1342 is opened in the shape of a hollow space at the upper and lower interiors, and the hollow spaces opened in the upper and lower parts of the first heating box 1342 are connected to each other, ensuring that the first heating box 1342 can achieve stable preheating processing activities on the upper and lower surfaces of the glass fiber cloth; the butt-jointed pipe 143 is movably plugged in along the upper and lower ends of the tee pipe 142, and the left and right ends of the butt-jointed pipes 143 on both sides are plugged in with the support rods 144, ensuring that the butt-jointed pipes 143 on both sides can move up and down along the tee pipe 142 to achieve movement and adjustment activities, so as to ensure that the second heating boxes 146 on both sides are closer to the glass fiber cloth and enhance the preheating effect; the support bar 147 is inserted into one side of the interior of the connecting shell 141 and is smoothly chamfered, and the outer chamfered end of the support bar 147 is opposite to the top of the butt-jointed pipes 143 on both sides on the left and right, ensuring that the support bar 147 can achieve stable support and cooperation for the entire connecting shell 141, and at the same time, when the connecting shell 141 is subsequently moved laterally, the distance between the second heating boxes 146 on both sides inside the connecting shell 141 can be flexibly adjusted.

[0040] Specifically, the glass fiber cloth can enter the preheating box 131 through the opening at the bottom of the preheating box 131, and can be transported to the right through the support roller 135 provided on the left side of the preheating box 131, so that the glass fiber cloth can pass through the opening on the right side of the preheating box 131 and enter the drying tower body 11. During the glass fiber cloth transmission process, the fan 132 provided at the upper end of the preheating box 131 can be driven to enable the fan 132 to realize the extraction of the hot air inside the drying tower body 11, and cooperate with the transmission pipe 133 connected to the inlet section of the fan 132 to allow the hot air to enter the transmission pipe 133. The two heat-conducting hoses 1341 connected at the lower ends can transmit hot air to the first heating box 1342 and the second heating box 146 respectively, so that the first heating box 1342 and the second heating box 146 can preheat the upper and lower surfaces of the glass fiber cloth to make the PTFE wear-resistant coating coated on the outer surface of the glass fiber cloth to perform surface curing activities, so as to ensure that when the PTFE wear-resistant coating enters the drying tower body 11 later, it is not easy to be blown by the hot wind and flow, resulting in the PTFE wear-resistant coating coating uniformity being affected;

[0041] At the same time, in order to enhance the preheating efficiency, the cylinder 1347 can be retracted to enable the cylinder to pull the connecting shell 141 to the right. In this way, the connecting belt 1345 docked at the lower end of the connecting shell 141 can be rotated and cooperated with the transmission roller 1346 connected on the left side to realize the leftward movement of the first heating box 1342 as a whole. As the first heating box 1342 moves to the left, the first heating box 1342 can realize the compression of the springs 1344 connected to the front and rear sides. Therefore, when the cylinder 1347 is subsequently extended, the springs 1344 compressed on both sides will rebound to realize the rightward movement and reset of the first heating box 134 as a whole. At the same time, the transmission of the connecting belt 1345 and the transmission roller 1346 is coordinated again to assist the leftward movement and reset of the second heating box 146. In this way, the first heating box 1342 and the second heating box 146 can be relatively moved in the opposite direction, realizing reciprocating lateral movement preheating, and enhancing the preheating coordination of the outer surface coating of the glass fiber cloth.

[0042] Moreover, when the connecting shell 141 moves rightward with the cylinder 1347, the support bars 147 connected to the upper and lower ends of the right side of the connecting shell 141 can be inserted into the upper and lower interiors of the connecting shell 141 to relatively contact with the butt joints 143 provided at the upper and lower interiors of the rear side of the connecting shell 141, so that the butt joints 143 on both sides are inserted and squeezed by the support bars 147 and relatively move up and down along the outer side of the three-way pipe 142. In this way, the second heating boxes 146 connected to the front ends of the butt joints 143 on both sides can be synchronously driven to make the second heating boxes 146 on both sides closer to the upper and lower surfaces of the glass fiber cloth, so as to enhance the preheating effect of the hot air on the outer surface of the glass fiber cloth. Secondly, when the butt-jointed tubes 143 on both sides move up and down relative to each other, the support rods 144 plugged in on the left and right sides can be cooperated to ensure the stability of the up and down movement. At the same time, when the support rods 144 on both sides move relative to each other, the compression springs 145 arranged at the outer ends of the support rods 144 on both sides will be compressed. In this way, when the connecting shell 141 is subsequently reset to the left along with the cylinder 1347, the compressed compression springs 145 can push the butt-jointed tubes 143 on both sides outward, so that the butt-jointed tubes 143 on both sides correspondingly drive the second heating boxes 146 on both sides to quickly reset, thereby achieving the advantage of auxiliary preheating of the outer coating of the glass fiber cloth to enable its initial solidification and anti-flow.

[0043] See also Figure 6-7The scraping assembly 136 in this embodiment includes a rectangular shell 1361 installed at the lower left end of the preheating box 131, a moving frame 1362 built into the rectangular shell 1361, scraping strips 1363 symmetrically connected to the left and right sides of the moving frame 1362 for scraping the outer coating of the glass fiber cloth, and spring sheets 1364 correspondingly arranged on the sides of the scraping strips 1363 on both sides for elastic pressure support, docked on the left and right sides of the moving frame 1362 and arranged in the rectangular shell 1361. The dampers 1365 on both sides of the interior correspond to the return springs 1366 arranged on the outer sides of the upper ends of the dampers 1365 on both sides. Through the cooperation of the dampers 1365 and the return springs 1366, the movable frame 1362 can be automatically moved upward and reset when it is driven to move downward. The downward pressing structure 15 installed at the upper end of the interior of the rectangular shell 1361 can move with the transmission of the preheating component 134 to intermittently press down the movable frame 1362, and one side of the downward pressing structure 15 is connected to the preheating component 134.

[0044] The downward pressure structure 15 includes a transmission frame 151 which is laterally embedded in the outer side of the upper end of the rectangular shell 1361 and is in the shape of an inverted door frame, a horizontal bar 152 which is laterally fastened to the right side of the transmission frame 151 and connected to the lower end of the auxiliary thermal structure 14 and can cooperate with the auxiliary thermal structure 14 to perform push-pull work, a transmission groove 153 which is opened on both sides of the transmission frame 151 and can realize downward pressure transmission cooperation, and a connecting shaft 154 which is connected to the inside of the transmission grooves 153 on both sides and is vertically installed, and the overall number of the connecting shafts 154 is not less than four, connected A pressing plate 155 is provided at the lower end of the four connecting shafts 154 for downward pressure transmission, and there is a gap between the bottom of the pressing plate 155 and the moving frame 1362. Protrusions 156 are fixedly connected to the four corners of the lower end of the pressing plate 155, and the protrusions 156 arranged on the four sides are in contact with the upper ends of the scraping strips 1363 arranged on both sides inside the moving frame 1362. In this way, when the pressing plate 155 is pressed downward, the protrusions 156 and the scraping strips 1363 can be used to resist each other, so as to enhance the scraping quality of the outer coating of the glass fiber cloth by the scraping strips 1363.

[0045] Among them, the scraper strips 1363 are symmetrically arranged along the left and right inside of the movable frame 1362, and the scraper strips 1363 on both sides are arranged in opposite V-shaped strips, ensuring the efficient combination of the scraper strips 1363 on both sides to achieve the flattening treatment of the outer coating of the fiberglass cloth; the transmission grooves 153 are opened in pairs along the inside of the two ends of the transmission frame 151, and the shape of the transmission grooves 153 is Z-shaped, so that the transmission grooves 153 can be stably combined with the connecting shaft 154, and move with the transmission frame 151 to achieve intermittent downward pressure transmission.

[0046] Specifically, when the glass fiber cloth enters the preheating box 131, it will enter the rectangular shell 1361 provided inside the lower left end of the preheating box 131 to contact with the scraping strips 1363 provided on both sides of the moving frame 1362, and the scraping strips 1363 on both sides can ensure the stability of the contact state through the spring sheets 1364 provided on the sides. In this way, during the transmission of the glass fiber cloth, the scraping action of the scraping strips 1363 on both sides can make the coating on the outer surface of the glass fiber cloth smooth, reduce potholes, and improve the subsequent drying quality of the glass fiber cloth.

[0047] When the connecting belt 1345, the driving roller 1346 and the cylinder 1347 provided inside the preheating assembly 134 realize the reciprocating transverse transmission activity, the horizontal bar 152 connected to the lower end of the connecting shell 141 will move accordingly. When the horizontal bar 152 moves down, the transmission frame 151 provided on the left side of the horizontal bar 152 will transmit the transmission to the connecting shaft 154 provided on the upper end of the pressing plate 155 through the transmission grooves 153 provided on both sides of the interior, so that the pressing plate 155 can realize the intermittent downward pressing activity as a whole. When the pressing plate 155 is pressed down, the protrusions 156 provided at the four corners of the bottom of the pressing plate 155 will cooperate with the scraping strips 1362 provided on both sides of the interior of the moving frame 1362 to move the scraping strips 1362 provided on both sides of the interior of the moving frame 1362. 63 performs a pressing activity to further strengthen the tightness between the scraping strips 1363 on both sides and the glass fiber cloth. Subsequently, the pressing plate 155 will realize the downward pressing of the moving frame 1362 as a whole, so that the moving frame 1362 drives the scraping strips 1363 on both sides to move downward and scrape, thereby enhancing the scraping efficiency. When the moving frame 1362 moves downward, the damper 1365 and the return spring 1366 installed on the left and right sides of the moving frame 1362 can cooperate with each other to realize the rear side return transmission activity, so that the moving frame 1362 is in a stable up and down moving state as a whole, thereby achieving the advantage of preheating the glass fiber cloth and realizing the auxiliary scraping of the outer coating of the glass fiber cloth.

[0048] See also Figure 8 The collecting assembly 137 in this embodiment includes a collecting box 1371 installed at the bottom of the left side of the preheating box 131 for collecting excess paint, side panels 1372 symmetrically fixedly connected to the left and right sides of the upper end of the collecting box 1371, buckles 1373 connected to the upper ends of the side panels 1372 on both sides for quick clamping, a locking piece 1374 clamped to the outside of the buckle 1373, and the locking piece 1374 is made of elastic material as a whole, a fixed shell 1375 installed on the outside of the locking piece 1374 and connected to the outside of the lower end of the preheating box 131, and a collecting port 1376 is opened at the lower end of the preheating box 131.

[0049] Among them, two collecting spaces are opened inside the collecting box 1371, and the collecting spaces on both sides are not connected, so as to ensure that there is an escape space in the middle of the collecting box 1371, so that the fiberglass cloth can stably enter the preheating box 131 to realize the preheating activity.

[0050] Specifically, the excess paint scraped off by the scraping strips 1363 on both sides of the movable frame 1362 can fall into the collecting spaces on both sides of the collecting box 1371 along the two collecting ports 1376 opened at the lower left end of the preheating box 131, so as to prevent the scraped paint from polluting external equipment. If it is necessary to clean the paint inside the collecting box 1371, it is only necessary to directly pull down the entire collecting box 1371 to quickly release the elastic snap connection between the buckle 1373 and the locking member 1374, so as to clean the paint inside the collecting box 1371. When reinstalling, it is only necessary to align the buckle 1373 and the locking member 1374 to re-realize the elastic snap connection between the buckle 1373 and the locking member 1374, so that the collecting box 1371 can be reinstalled to the lower left end of the preheating box 131 to be opposite to the collecting port 1376 above and below, thereby achieving the advantage of auxiliary collection and cleaning of excess paint.
