Description

Technical Field

[0001] This invention relates to a reusable tape reel and its method of use. Background Technology

[0002] Belt conveyors are the main transportation equipment in fully mechanized mining faces, installed in the face roadways. Currently, the coal mining method commonly used in large and medium-sized mines in my country is longwall mining. Initially, the belt conveyor belts are arranged at their longest length, typically 1000-3000 meters. As mining progresses, the conveyor belt needs to be gradually shortened. The belt storage bin is used to temporarily store and tension the shortened belt in real time. When the storage bin is full (approximately 100 meters), the belt must be removed, rolled up, and transported away.

[0003] With the improvement of coal mining technology and the automation level of fully mechanized mining equipment, the production capacity of the corresponding working face has been significantly improved, thus posing higher requirements and challenges to the transportation efficiency of belt conveyors and other equipment.

[0004] In existing belt winding devices, the belt winding rollers attached to the belt conveyor are mostly designed as a single unit at the factory, and their original design model is an integral iron cylinder model, which cannot be reused. They are wound inside the shaft of the entire roll of belt each time, making them difficult to disassemble. Each time the belt is wound, a new winding roller needs to be manufactured, resulting in waste. For example, the remote-controlled hydraulic belt winding device for underground coal mines disclosed in Chinese utility model patent CN 216863099 U, published on July 1, 2022, requires… The winding roller (i.e., the winding shaft) and the conveyor belt are transported together to the coal mine. ".

[0005] To address this, a specially designed, easily disassembled and reassembled combination reel shaft has been developed—see the "Detachable Roller for a Reel-in Device" disclosed in Chinese Utility Model Patent No. CN 205312483 U, published on June 15, 2016. This design includes two identical half-rollers, which are joined together and fixed at both ends by end caps. The end caps have square holes for the roller shaft to pass through. At the two joints, each half-roller has an axial rectangular slot on its roller surface. A belt clip is mounted axially on the roller surface of one half-roller. Disassembly is simple; the end caps are opened on both sides. The roller can be reused. However, the reel-in device needs to wind up hundreds of meters of tape each time, which is very heavy and subject to high winding stress, making it prone to damage. Furthermore, after winding, the tape is tightly wound... Detachable rollers for tape winding devices cylinder "On top, the two half rollers are difficult to pull out."

[0006] Chinese invention patent application CN 116902641 A, published on October 20, 2023, discloses a variable frequency belt winding device for a belt conveyor and its usage method. The specification of this invention states: The tape reel is provided with a fixing screw. bolt "exist" S3: Secure the tape joint using the two fixing bolts on the tape reel. " Remove the fixing screws on both sides of the tape reel (5) The tape roll is unloaded from the reel and loaded onto a vehicle for recycling. ", not disclosed" The position and shape of the fixing bolts The attached diagram does not disclose the specific structure of its tape reel. As mentioned earlier, when the tape reel is in operation, the tape is wound onto the reel, and the fixing bolts are caught in it, making them difficult to remove.

[0007] There is an urgent need for a reusable tape reel with a simple structure, that is not easily damaged, allows ropes or straps to pass through the middle of a roll of matching tape, and is easy to loosen and disassemble, as well as a method for its use. Summary of the Invention

[0008] The technical problem to be solved by the present invention is how to overcome the above-mentioned defects of the prior art and provide a reusable tape combination roll and its usage method, which is easy to pass through the middle of the roll of matching tape with a rope or strap, and is easy to loosen and disassemble.

[0009] To solve the above-mentioned technical problems, this reusable tape reel includes a tape reel shaft that can be connected to and driven by a drive shaft of a tape reeling device. The tape reel shaft has a square or rectangular cross-section and also includes two conical sleeves and a cable or strap. Each conical sleeve includes a square tube with a rectangular cross-section. One side wall of the square tube is connected to a clamping plate with an L-shaped cross-section. The clamping plate and the side wall of the square tube form a tape-clamping groove. The other three side walls of the square tube are respectively provided with wedges. The small end of each wedge is engaged with the square tube. One end of the wedge is connected to the other end of the square tube to form the small end of the cone sleeve. The large end of the wedge is connected to the other end of the square tube to form the large end of the cone sleeve. Both cone sleeves are fitted on the tape reel. The small ends of the two cone sleeves are adjacent and the slots of the two sleeves face the same direction. The end of the tape is inserted into the slots of the two cone sleeves. The tape is wound on the tape reel between the two cone sleeves. A fan-shaped through gap is formed between the middle wedge and the wedges on both sides. The rope or strap passes through one or two through gaps and is used to tie and fix the tape.

[0010] The tape reel and its two tapered sleeves are both fixed structures with no threaded parts. The tapered sleeves are fitted onto the tape reel and can move along the reel. After the tape is wound, a rope or strap can be passed through one or two through gaps to secure the roll of tape.

[0011] After the roll of matching tape is cut from the original matching tape, the rolled matching tape is also tightly wound onto the reusable tape assembly roll of the present invention. However, since both conical sleeves in the present invention have their small ends facing inward, as long as one conical sleeve on the roll is pulled outward or knocked outward, the two conical sleeves on the roll will loosen from the rolled matching tape and can be easily removed for the next use.

[0012] This design is simple, sturdy, easy to use, and allows ropes or straps to pass through the middle of the roll of matching tape.

[0013] As an optimization, each wedge is composed of triangular blocks. This design results in a simple and robust structure.

[0014] As an optimization, each wedge includes two triangular ribs, which are parallel to each other. Through holes are formed on the triangular ribs of the middle wedge and / or the triangular ribs adjacent to the middle wedge. This design results in a lightweight double-triangular rib structure for the wedge.

[0015] As an optimization, a connecting plate is also added between the two triangular ribs of the same wedge. With this design, the wedge has a hollow structure and is lighter in weight.

[0016] The method of using the aforementioned reusable tape roll includes the following steps: ①. Place the two cone sleeves onto the tape reel shaft, with their small ends facing inwards, and the distance between the small ends of the two cone sleeves should be less than the width of the tape being used and less than the distance between the large ends of the two cone sleeves.

[0017] ②. Fix one end of the tape reel to the drive shaft of the tape reeling device, disconnect the tape from the appropriate position, and insert the tape end of the tape to be recycled into the tape slots of the two cone sleeves.

[0018] ③. Start the tape reel device to rotate the tape reel shaft and wind the tape to be recycled onto the tape reel shaft between the two cone sleeves, forming a fan-shaped through gap between the middle wedge and the wedges on both sides.

[0019] ④. Then take a cable tie or strap, pass it through the gap, and then wrap it around the outer circumference of the rolled tape, tighten and fix it, and then use a cutter to cut the rolled tape off the matching tape to form a roll of matching tape.

[0020] ⑤. Remove the tape reel along with the roll of tape attached to it from the drive shaft of the tape reel device.

[0021] ⑥. Remove one or two cone sleeves from the reel, then pull the reel from the roll of matching tape. Transport the roll of matching tape to the warehouse. The reel and the two cone sleeves can be reused and do not need to be lifted to the well.

[0022] This design allows for easy assembly and disassembly of the tape reel and the two cone sleeves. Furthermore, without removing the reusable tape assembly reel, the binding rope or strap can be easily passed through the middle of the roll of matching tape to secure it. The binding rope or strap does not affect the disassembly of the tape reel and the two cone sleeves.

[0023] As an optimization, at the end of step ①, take a piece of No. 8 or No. 10 wire and place it on the same side of the middle wedge of the two cone sleeves, so that both ends of the No. 8 or No. 10 wire pass through the through holes on the same side of the two cone sleeves, then bend it back and connect it to itself to fix the distance between the two cone sleeves; in step ⑥, before removing the cone sleeves, cut the No. 8 or No. 10 wire. With this design, the distance between the two cone sleeves will not increase during the winding process.

[0024] The reusable tape combination roll of this invention has a simple structure, is not easily damaged, and is reusable. It is easy to pass ropes or straps through the middle of the roll of matching tape to bind and fix the roll of matching tape. It is also easy to loosen and disassemble, which is very convenient and suitable for use in coal mine belt conveyors. Attached Figure Description

[0032] The method of using the aforementioned reusable tape roll includes the following steps: ①. Place two cone sleeves 2 onto the tape reel 1 respectively, with their small ends inside, and the distance L1 between the small ends of the two cone sleeves 2 is less than the width L2 of the tape to be used and less than the distance L3 between the large ends of the two cone sleeves.

[0033] Take a piece of No. 8 or No. 10 iron wire 8 and place it on the same side of the middle wedge 4 of the two conical sleeves 2. Pass both ends of the No. 8 or No. 10 iron wire 8 through the through holes 7 on the same side of the two conical sleeves 2, then bend it back and connect it to itself to fix the distance between the two conical sleeves 2. Figure 6 As shown.

[0034] ②. Fix one end of the tape reel 1 to the drive shaft of the tape reel device, disconnect the tape 5 from the appropriate position, and insert the tape end 51 of the tape 5 to be recycled into the tape slots 23 of the two cone sleeves 2.

[0035] ③. Start the tape reel device to rotate the tape reel shaft 1 and wind the tape 5 to be recycled onto the tape reel shaft 1 between the two cone sleeves 2, forming a fan-shaped through gap 6 between the middle wedge 4 and the wedges 4 on both sides.

[0036] ④. Then take the cable tie or strap 3, pass it through the through-gap 6, and then wrap it back around the outer circumference of the rolled tape, tightening and securing it. Then use a cutter to cut the rolled tape from the matching tape, forming a roll of matching tape 5, as shown. Figure 7 As shown.

[0037] ⑤. Remove the tape reel 1 together with the roll of adhesive tape 5 on it from the drive shaft of the tape reel device.

[0038] ⑥. First, cut the No. 8 or No. 10 iron wire to the desired length. Figure 8 As shown.

[0039] Then remove one or two cone sleeves 2 from the tape reel 1, and then pull the tape reel 1 out of the roll of matching tape 5. The packaged roll of matching tape 5—such as Figure 9 As shown, the tape reel 1 and the two cone sleeves 2 are transported to the warehouse and can be reused.
