Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a winding head positioning device. Background Technology

[0002] In continuous strip production, the coiler is a key piece of equipment for collecting finished products. When the strip begins to wind on the drum, the end of the strip, i.e., the strip head, needs to be stably fixed to the drum surface to ensure smooth winding and a neat coil shape. In existing technologies, simple clamping blocks are typically installed on the drum surface, or friction is used to fix the strip head. While these methods are simple in structure, in practical applications, especially under high-speed winding or thin strip conditions, the strip head is prone to insecure fixing, loosening, or even slippage. This not only affects winding quality but may also lead to production line downtime and reduced production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a winding head positioning device, which solves the problem of the winding head not being firmly fixed and easily loosening and slipping by setting a locking arc-shaped positioning plate and positioning groove cooperation structure.

[0004] This utility model is achieved through the following technical solution: This utility model is a winding head positioning device, including a base, a positioning plate and a positioning groove. Two frames are installed on the top of the base. Each frame has a through hole at its top, and a horizontal shaft is fitted into each through hole. A winding drum is sleeved on the horizontal shaft. Rectangular blocks are installed on both sides of the positioning plate. Each rectangular block has a light hole, and a bolt is fitted into each light hole. Threaded holes are opened on both sides of the winding drum. The bottom ends of two bolts are threaded into the corresponding threaded holes. Through holes are opened on both sides of the winding drum, and a rotating shaft is fitted into each through hole. A horizontal hole is opened on one side of the positioning plate, and the positioning plate is sleeved on the rotating shaft through the horizontal hole.

[0005] Furthermore, a positioning groove is provided on the drum, and both through holes are connected to the positioning groove, with the positioning plate fitting inside the positioning groove.

[0006] Furthermore, a horizontal plate is installed at the bottom of the positioning plate, the bottom surface of the horizontal plate is provided with anti-slip texture, and the top of the positioning plate is provided with a first reserved groove.

[0007] Furthermore, a row of rings is fitted onto the rotating shaft, and a row of clearance grooves is opened on one side of the positioning plate. All the clearance grooves are connected to the transverse holes, and each ring is located in the corresponding clearance groove.

[0008] Furthermore, a torsion spring is fitted onto the rotating shaft, with its two ends connected to the top of the clearance groove and the outer surface of the torsion spring, respectively.

[0009] Furthermore, a row of abutments is installed on one side of the positioning groove, and a row of abutments is opened on the top of the side of the positioning plate near the rotating shaft, with each abutment fitting into its corresponding abutment.

[0010] Furthermore, limit rings are installed on both sides of the drum.

[0011] Furthermore, a drive assembly is provided on the top of the base. The drive assembly has a motor, sprockets and a chain. A motor is provided on the top of one side of the base. Sprockets are sleeved on both the end of the horizontal shaft and the output end of the motor. The chain is fitted on the two sprockets.

[0012] This utility model has the following beneficial effects: This utility model achieves mechanical clamping and fixing of the lead head by setting a positioning groove and an arc-shaped positioning plate, and by using bolts to cooperate with the threaded holes on both sides of the drum. By tightening the bolts, the positioning plate and the cross plate with anti-slip texture at the bottom can be firmly pressed against the bottom of the positioning groove, forming a stable clamping force, which effectively prevents the lead head from loosening or slipping due to vibration or tension changes during high-speed winding, and ensures the stability of the initial stage of winding. This utility model, through the setting of torsion spring, abutment groove and abutment block, when the bolt is loosened, the preload of the torsion spring will drive the positioning plate to automatically rotate outward around the axis and open until the abutment groove is blocked by the abutment block. At this time, the positioning plate is stable in the maximum opening position, forming a fixed operating space with the bottom of the positioning groove, which simplifies the operation process of placing and taking out the head. The operator does not need to manually find and fix the opening angle of the positioning plate, thereby improving the work efficiency.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: a winding head positioning device, including a base 1, a positioning plate 5, and a positioning groove 401. A driving assembly 14 is provided on the top of the base 1. The driving assembly 14 has a motor 1401, a sprocket 1402, and a chain 1403. The motor 1401 is provided on the top of one side of the base 1. The end of the horizontal shaft 3 and the output end of the motor 1401 are both sleeved with sprockets 1402. The chain 1403 is engaged with the two sprockets 1402. Starting the motor 1401 can drive the horizontal shaft 3 and the winding drum 4 to rotate through the chain drive to complete the winding operation. Two frames 2 are installed on the top of the base 1. The top of the two frames 2 is provided with through holes 201. The horizontal shaft 3 is fitted into the two through holes 201. The winding drum 4 is sleeved on the horizontal shaft 3. Limiting rings 13 are installed on both sides of the winding drum 4. 3 is used to axially limit the wound strip to prevent deviation. The drum 4 is connected to the horizontal shaft 3 by a key. The drum 4 has a positioning groove 401. Two through holes 402 are connected to the positioning groove 401. The positioning plate 5 is fitted in the positioning groove 401. The positioning groove 401 is used to accommodate the end of the strip. After the end is fixed, the motor 1401 is started. The motor 1401 drives the horizontal shaft 3 to rotate through the sprocket 1402 and the chain 1403, which in turn drives the drum 4 and the fixed end to rotate together, and the normal winding operation begins. During the entire winding process, the end will not loosen or slip because the positioning plate 5 is reliably locked by the bolt 7. When it is necessary to unwind or replace the strip, simply loosen the bolt 7, and the torsion spring 12 will automatically open the positioning plate 5 to the maximum opening position, making it easy to take out the end. The operation is simple and quick.

[0018] The positioning plate 5 is an arc-shaped plate, with rectangular blocks 6 installed on both sides. Each rectangular block 6 has a second pre-reserved groove 602. When the bolts 7 are tightened, the nuts of the bolts 7 are positioned within the second pre-reserved grooves 602, preventing obstruction of the winding operation. Each rectangular block 6 has a clear hole 601, and each clear hole 601 is fitted with a bolt 7. Each side of the drum 4 has threaded holes 403. The bottom ends of the two bolts 7 are threaded into the corresponding threaded holes 403. When the bolts 7 are tightened, the heads of the bolts 7 press against the rectangular blocks 6, and the bolts 7 are screwed into the threaded holes 403, thus firmly pressing the positioning plate 5 into the positioning grooves 401. A horizontal plate 9 is installed at the bottom of the positioning plate 5. The bottom surface of the horizontal plate 9 has anti-slip textures, which increase the friction between the horizontal plate 9 and the belt head, preventing slippage. To prevent slippage, the top of the positioning plate 5 is provided with a first reserved groove 501, which provides space for tools such as wrenches to apply force during operation. Both sides of the drum 4 are provided with through holes 402, and the two through holes 402 are fitted with rotating shafts 8. One side of the positioning plate 5 is provided with a horizontal hole, and the positioning plate 5 is sleeved on the rotating shaft 8 through the horizontal hole. After loosening the bolts 7, the end of the strip is inserted into the positioning groove 401 through the opening. Then, the positioning plate 5 is rotated toward the bottom of the positioning groove 401 to press the strip end. The horizontal plate 9 at the bottom of the positioning plate 5 and its anti-slip texture can effectively increase the clamping force on the strip end. Finally, the two bolts 7 are tightened with tools. The bolts 7, by pressing the rectangular block 6, firmly fix the positioning plate 5 and the strip end it holds in the positioning groove 401.

[0019] A row of rings 11 is fitted onto the rotating shaft 8. A row of clearance grooves 503 is formed on one side of the positioning plate 5. Each row of clearance grooves 503 is connected to a transverse hole. Each ring 11 is located in its corresponding clearance groove 503. A torsion spring 12 is fitted onto the rotating shaft 8. The two ends of the torsion spring 12 are connected to the top of the clearance groove 503 and the outer surface of the torsion spring 12, respectively. A row of abutments 10 is installed on one side of the positioning groove 401. A row of abutments 502 is formed on the top of the side of the positioning plate 5 closest to the rotating shaft 8. When the bolt 7 is loosened, the positioning plate 5 will rotate around the rotating shaft 8 under the elastic force of the torsion spring 12 and move outward from the positioning groove 401. The groove 502 on the positioning plate 5 is held in place by the block 10 on the inner wall of the positioning groove 401. At this time, the opening between the positioning plate 5 and the bottom of the positioning groove 401 is at its maximum, which facilitates the insertion of the head. Each block 10 is fitted into the corresponding groove 502. During operation, first loosen the two bolts 7. Under the restoring force of the torsion spring 12, the positioning plate 5 will rotate outward around the pivot 8, moving it away from the bottom of the positioning groove 401 until the groove 502 on the positioning plate 5 is held in place by the block 10. At this time, the positioning plate 5 is held in the maximum open position, and a large opening is formed between the positioning plate 5 and the bottom of the positioning groove 401.
