Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protective pipe wrapping packaging, in particular to a film wrapping device for large cable protective pipe production. BACKGROUND

[0002] Large cable protective pipes are indispensable infrastructure components in the fields of power, communication, transportation, etc., mainly used to protect cables from mechanical damage, chemical corrosion, ultraviolet radiation, and external environmental (such as moisture, dust, insects, etc.) intrusion. Protective pipes are usually made of high-strength, weather-resistant materials such as PVC (polyvinyl chloride) or MPP (modified polypropylene) to ensure their long-term reliability and durability in complex environments.

[0003] During transportation and storage, the surface of the protective pipe is prone to scratches, wear, contamination, and even chemical corrosion. These damages not only affect the appearance quality of the protective pipe, but also may reduce its mechanical strength and protective performance. To solve this problem, a protective film is usually wrapped around the surface of the protective pipe to protect it.

[0004] Current film wrapping equipment can only wrap the circumference of the protective pipe, leaving the two end faces exposed to the outside. During transportation and storage, dust, sand, and other contaminants can easily enter the protective pipe through the uncoated end and adhere to the inner wall. Dust may cause the insulation performance of the cable to decrease, increasing the risk of short circuit or electric leakage, affecting the reliability of electrical connections. In addition, during transportation and storage, the protective pipe often rubs against the ground, other pipes, or tools. Since the end of the protective pipe is not coated with a protective film, it is prone to scratches, wear, and even breakage, making the protective pipe more prone to cracking or breaking during subsequent use and failing to effectively protect the internal cable. SUMMARY

[0033] refer to Figure 3 ,Figure 4 , Figure 6 and Figure 7 The conveying assembly includes a support frame 1212, a support ring 1213, a first slide bar 1214, a first moving plate 1215, a first cylinder 1216, a first electric roller 1217, and a first auxiliary wheel 1218. Two support frames 1212 are bolted to the top right side of the frame 1. The two support frames 1212 are arranged opposite each other. A support ring 1213 is bolted to the upper part of both support frames 1212. Four sets of first slide bars 1214 are slidably connected to the outer circumference of the support ring 1213 at even intervals. Each set has two first slide bars. The slide rod 1214, the two first slide rods 1214 in the same group are arranged to face each other from left to right, and the two first slide rods 1214 in the same group are connected to the first moving plate 1215. The support ring 1213 is evenly spaced around the outside of the ring by bolts and four first cylinders 1216 are evenly spaced around the outside of the ring. The telescopic rod of the first cylinder 1216 is connected to the first moving plate 1215. The first moving plate 1215 is equipped with first electric rollers 1217 on both the left and right sides. The four first moving plates 1215 are evenly spaced around each other and connected to first auxiliary wheels 1218.

[0034] refer to Figure 8 and Figure 9 The conveying mechanism includes a second slide rod 131, a second moving plate 132, a second cylinder 133, a second electric roller 134, and a second auxiliary wheel 135. Four sets of second slide rods 131 are slidably connected to the outer circumference of the mounting ring 3 at uniform intervals. Each set has two second slide rods 131, and the two second slide rods 131 in the same set are arranged opposite each other to the left and right. The two second slide rods 131 in the same set are connected to the second moving plate 132. Four second cylinders 133 are bolted to the outer circumference of the mounting ring 3 at uniform intervals. The telescopic rods of the second cylinders 133 are connected to the second moving plate 132. Second electric rollers 134 are installed on both the left and right sides of the second moving plate 132. The side of the four second moving plates 132 that is close to each other is rotatably connected to the second auxiliary wheel 135 at uniform intervals.

[0035] refer to Figure 8 The bonding mechanism includes a first electric push rod 141, a first connecting frame 142 and a pressure roller 143. The first electric push rod 141 is bolted to the lower left side of the connecting plate 9. The front end of the telescopic rod of the first electric push rod 141 is bolted to the first connecting frame 142. The pressure roller 143 is rotatably connected to the front side of the first connecting frame 142.

[0036] The worker places a roll of protective film onto the unwinding shaft 125 (using a protective film pre-cut with multiple complete circular die-cut lines, containing multiple circular units; the circular units can be easily peeled off the protective film with slight force, resulting in a neat, usable circular protective film). Then, the worker pulls the protective film downwards, passing it through two guide rollers 126, and then winds it onto the take-up shaft 1210, ensuring the circular units on the protective film completely cover the conical rubber sleeve 128. The protective tube is then placed into the support ring 1213. The first electric roller 1217 and the first auxiliary roller 1218 will contact the protective tube. The first electric roller 1217 feeds the protective tube to the left, and the first auxiliary roller 1218 assists in feeding the protective tube. The protective tube will push the circular units on the protective film... The protective tube is then peeled off from the circular unit on the protective film. The circular protective film will cover the left end of the protective tube. One side of the circular protective film has slight adhesion, so it can stick to the left end of the protective tube. The protective tube then moves into the conical rubber sleeve 128, which expands outward and forms an inward closing force. At this time, the first electric roller 1217 continues to feed the protective tube to the left. The conical rubber sleeve 128 presses down on the circular protective film covering the left end of the protective tube, ensuring the circular protective film adheres tightly to the protective tube and preventing it from falling off. The protective tube then enters the mounting ring 3 and contacts the second electric roller 134 and the second auxiliary roller 135. The second electric roller 134 feeds the protective tube to the left, and the second auxiliary roller 135 assists in feeding the protective tube. The protective tube and the conical rubber sleeve 128 disengage, and the conical rubber sleeve 128 closes inward to return to its original shape. Then, the output shaft of the fifth motor 129 drives the take-up shaft 1210 to rotate, and the take-up shaft 1210 winds up the remaining protective film material, ensuring that the next circular unit on the protective film completely covers the conical rubber sleeve 128. At the same time, the output shaft of the fourth motor 124 drives the unwind shaft 125 to rotate, and the unwind shaft 125 releases the protective film, preventing the take-up shaft 1210 from pulling on the protective film. The guide roller 126 guides the protective film, keeping it in a vertical position. Then, the output shaft of the third motor 122 is controlled to rotate 180 degrees, driving the rotating plate 121 to rotate 180 degrees. The rotating plate 121 drives the n-shaped frame 123 to rotate 180 degrees. This causes the conical rubber sleeve 128 to rotate 180 degrees, turning it to cover the right end of the protective tube with a protective film. At this time, the second electric roller 134 feeds the protective tube to the right, and the second auxiliary roller 135 assists in feeding the tube. The protective tube pushes the circular units on the protective film, peeling them off. The circular protective film then covers the right end of the protective tube. One side of the circular protective film is slightly adhesive, allowing it to adhere to the right end. The protective tube then moves into the conical rubber sleeve 128, which expands outward and creates an inward closing force. The second electric roller 134 continues to feed the protective tube to the right, and the conical rubber sleeve 128 presses down on the circular protective film covering the right end of the protective tube.To ensure the circular protective film adheres tightly to the protective tube and prevents it from falling off, the second electric roller 134 feeds the protective tube to the left, while the second auxiliary roller 135 assists in feeding the protective tube. The protective tube is fed to below the placement shaft 10, where it disengages from the conical rubber sleeve 128, which then closes inward to return to its original shape. A roll of protective film is then placed onto the placement shaft 10, and the film is pulled downwards to the front of the pressure roller 143. The extension rod of the first electric push rod 141 is extended, causing the first connecting frame 142 to move forward. A connecting frame 142 drives a pressure roller 143 to move forward. The pressure roller 143 pushes the protective film forward, adhering it to the circumferential side of the protective tube and pressing it down. One side of the protective film has slight adhesiveness, allowing it to adhere to the circumferential side of the protective tube. Then, the output shaft of the first motor 7 drives the first gear 8 to rotate, which in turn drives the first gear ring 5 to rotate. The first gear ring 5 then drives the connecting plate 9 to rotate, which in turn drives the protective film and the pressure roller 143 to rotate. The protective film and the pressure roller 143 rotate around the protective tube, wrapping the protective film around the circumference of the protective tube. On the periphery, the pressure roller 143 can press the protective film, ensuring it adheres tightly to the protective tube and preventing it from falling off. Simultaneously, the second electric roller 134 continues to convey the protective tube to the left, wrapping the entire tube with the protective film. This protective film covers the circular protective films at both ends of the tube, further securing them and preventing them from falling off. The circular protective film covering both ends of the tube prevents dust, impurities, and other debris from entering and avoids damage to the tube's sides. The extension rod of the first cylinder 1216 can drive... The first movable plate 1215 moves, which in turn moves the first electric roller 1217. The distance between the first electric rollers 1217 can be adjusted according to the diameter of the protective tube. The extension rod of the second cylinder 133 moves the second movable plate 132, which in turn moves the second electric roller 134. The distance between the second electric rollers 134 can also be adjusted according to the diameter of the protective tube.

[0037] refer to Figure 10It also includes a pulling mechanism, which includes a second gear ring 151, a sixth motor 152, a rotating shaft 153, a second gear 154, a winding wheel 155, a pull rope 156, and a pull plate 157. The second gear ring 151 is rotatably connected to the outside of the connecting ring 127. The sixth motor 152 is bolted to the top of the connecting ring 127. Five rotating shafts 153 are rotatably connected to the outside of the connecting ring 127 at even intervals. The output shaft of the sixth motor 152 and the rotating shaft 153 are both connected to the second gear 154 by keys. The second gear 154 meshes with the second gear ring 151. The output shaft of the sixth motor 152 and the rotating shaft 153 are both connected to the winding wheel 155. The pull rope 156 is wound on the winding wheel 155. Six pull plates 157 are evenly connected to the left side of the conical rubber sleeve 128 at even intervals. The pull rope 156 is connected to the pull plate 157.

[0038] After the right end of the protective tube is covered with a circular protective film, the second electric roller 134 conveys the protective tube to the left. At this time, the conical rubber sleeve 128 is still in contact with the protective tube. The conical rubber sleeve 128 may pull off the circular protective film covering the right end of the protective tube. The operator can control the output shaft of the sixth motor 152 to rotate. The output shaft of the sixth motor 152 drives the second gear 154 to rotate. Through the second gear ring 151, all the second gears 154 can be rotated, thereby enabling all the winding wheels 155 to rotate. The winding wheels 155 wind up the pull rope 156, and the pull rope 156 pulls the pull plate 157, causing the six pull plates 157 to rotate. 7. Open in a direction away from each other, push the conical rubber sleeve 128 outward, so that the conical rubber sleeve 128 and the protective tube are no longer in contact, and prevent the conical rubber sleeve 128 from pulling off the circular protective film covering the right end of the protective tube. After the protective tube is delivered to the bottom of the placement shaft 10, control the output shaft of the sixth motor 152 to rotate in the reverse direction. The output shaft of the sixth motor 152 drives the second gear 154 to rotate in the reverse direction. Through the second gear ring 151, all the second gears 154 can rotate in the reverse direction, thereby enabling all the winding wheels 155 to rotate in the reverse direction. The winding wheels 155 release the pull rope 156, and the conical rubber sleeve 128 closes inward to return to its original state.

[0039] refer to Figure 11 It also includes a cutting mechanism, which includes a second electric push rod 161, a second connecting frame 162 and a cutter 163. The second electric push rod 161 is bolted to the lower left side of the connecting plate 9. The second electric push rod 161 is located above the first electric push rod 141. The front end of the telescopic rod of the second electric push rod 161 is bolted to the second connecting frame 162. The cutter 163 is connected to the front side of the second connecting frame 162.

[0040] After the protective film is wrapped, the extension rod of the second electric push rod 161 is extended, which drives the second connecting frame 162 to move forward. The second connecting frame 162 drives the cutter 163 to move forward, and the cutter 163 can cut the protective film automatically without manual intervention, realizing continuous and unmanned operation, greatly shortening the wrapping time and improving work efficiency.

[0041] refer to Figure 11 It also includes an electric conveyor roller 17. Two electric conveyor rollers 17 are installed in the middle of the left side of the connecting plate 9. The two electric conveyor rollers 17 are arranged in a front-to-back arrangement. The outer surface of the electric conveyor roller 17 is made of Teflon material, and the protective film will not stick to the outer surface of the electric conveyor roller 17.

[0042] The worker places a roll of protective film onto the placement shaft 10 and pulls the protective film downwards, passing it between the two electric conveying rollers 17. Finally, the protective film is pulled to the front of the pressure roller 143. During the film wrapping process, the electric conveying rollers 17 can transport the protective film and pull it off the placement shaft 10, reducing the strain on the protective film and preventing it from breaking.
