Description

Technical Field

[0001] This application relates to the field of strip winding and unwinding technology, and in particular to an anti-drop mechanism for strip winding and unwinding. Background Technology

[0002] Winding mechanisms are widely used in many industries, such as non-ferrous metals, steel, papermaking, plastics, printing, rubber, textiles, and cables.

[0003] The winding and unwinding mechanism includes a fixed base and a rotating spindle. A drive motor is mounted on the fixed base, and the rotating spindle is coaxially fixed on the drive motor. A reel for outward expansion or inward contraction is set on the rotating spindle. A limit block for axially limiting the reel is set on the fixed base. The rotating spindle drives the reel to rotate through the drive motor, and simultaneously winds or unwinds the continuously conveyed strip material with a set tension. During the winding or unwinding process, the diameter of the strip material on the reel changes continuously.

[0004] For some strip materials with poor elasticity, when the roll diameter is large, they are prone to falling off the reel, which affects the normal winding or unwinding of the strip material, and there is room for improvement. Utility Model Content

[0005] To prevent strip material from falling off the winding and unwinding mechanism, this application provides a strip winding and unwinding anti-drop mechanism.

[0006] This application provides a strip winding and unwinding anti-drop mechanism, which adopts the following technical solution:

[0007] A strip winding and unwinding anti-drop mechanism includes a rotating main shaft coaxially fixed on the output shaft of a drive motor. A support disk is detachably mounted on the rotating main shaft. Multiple support disks are arranged in a circumferential array to form a winding reel for winding and unwinding strip material. A support rod for supporting dropped strip material is detachably mounted on the support disk. The support rod is arranged along the axial direction of the rotating main shaft.

[0008] By adopting the above technical solution, multiple support discs are used to form a reel, which allows the strip material to be stably wound on the reel so that the winding and unwinding operations can proceed normally. With the support rods, when the strip material with poor elasticity falls from the reel, the support rods can further support the falling strip material, reducing the possibility of the strip material falling to the ground.

[0009] Preferably, the support rod is threaded onto the support disc.

[0010] By adopting the above technical solution, the support rod is threadedly connected to the support plate. This connection method facilitates installation and disassembly, improving the convenience of operation. At the same time, the staff can adjust the length of the support rod as needed, improving the flexibility and practicality of the support rod.

[0011] Preferably, the support rod is inserted into the support plate, and the support plate is provided with a limiting bolt for limiting the position of the stop rod.

[0012] By adopting the above technical solution, the support rod and the support plate are connected by a plug-in joint, so that the staff can adjust the length of the support rod as needed. When the length of the support rod is adjusted to a suitable position, the support rod is limited by the limit bolt, thereby improving the stability of the support rod. This connection method reduces the possibility of the strip material falling to the ground during the winding and unwinding process.

[0013] Preferably, a drive screw is threadedly connected to the rotating spindle along its axial direction, and the support plate includes a connecting plate, a fixing block and a plate body. One end of the connecting plate is rotatably connected to the rotating spindle, and the other end of the connecting plate is rotatably connected to the fixing block. The side of the fixing block away from the rotating spindle is disposed on the plate body, and a sliding block is disposed on the plate body. The sliding block is slidably disposed on the limiting block.

[0014] By adopting the above technical solution, when the operator operates the drive screw to rotate, the rotating spindle will move on the drive screw. Since one end of the connecting plate is rotatably connected to the rotating spindle and the other end is rotatably connected to the fixed block, and the limiting block axially limits the sliding block, that is, the sliding block can only move radially along the rotating spindle, thereby the rotating spindle drives the connecting plate to swing, and then the connecting plate drives the fixed block and the disc to expand or contract outward to adapt to strip materials of different thicknesses or weights.

[0015] Preferably, a stop bar for preventing the strip material from falling is rotatably connected to one end of the support rod away from the support plate.

[0016] By adopting the above technical solution and using the baffle, the possibility of strip material falling to the ground is further reduced, making the use of the winding and unwinding mechanism more convenient and reliable.

[0017] Preferably, the support rod is provided with a rotating pin, the stop rod is rotatably connected to the rotating pin, and a locking nut is threaded onto the rotating pin, the locking nut forming an abutting fit with the support rod.

[0018] By adopting the above technical solution, and using the stop bar and the rotating pin to form a rotating connection, the staff can adjust the angle of the stop bar as needed to adapt to strip materials of different widths or thicknesses, thereby improving the effectiveness of the stop bar anti-fall mechanism.

[0019] Preferably, the end of the stop bar near the support rod is provided with a relief ramp for avoiding the support rod.

[0020] By adopting the above technical solution and utilizing the avoidance slope, the possibility of wear caused by collision between the stop bar and the support bar is reduced, thereby enabling the stop bar to rotate smoothly on the rotating pin.

[0021] Preferably, the end of the drive screw away from the main rotating shaft is provided with a rotating sleeve to facilitate the operator to turn the drive screw.

[0022] By adopting the above technical solution and utilizing the rotating sleeve, the operator can easily turn the drive screw, thus improving the ease of operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The use of multiple support discs to form a reel allows the strip material to be stably wound on the reel, ensuring the normal operation of the winding and unwinding process; the use of support rods further supports the strip material when it falls from the reel, reducing the possibility of it falling to the ground.

[0025] 2. The support rod is threaded onto the support plate, which facilitates installation and disassembly, improving operational convenience. Furthermore, operators can adjust the length of the support rod as needed, enhancing its flexibility and practicality.

[0026] 3. The use of the baffle further reduces the possibility of the strip material falling to the ground, making the winding and unwinding mechanism more convenient and reliable to use. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses an anti-drop mechanism for strip winding and unwinding.

[0035] Example 1:

[0036] Reference Figure 1 A strip winding and unwinding anti-drop mechanism includes a rotating spindle 1, which is coaxially fixed with the output shaft of a drive motor. A support plate 2 is detachably mounted on the rotating spindle 1. Multiple support plates 2 are provided. In this embodiment, four support plates 2 are arranged in a circumferential array, and the four support plates 2 together form a reel for winding or unwinding strip material. Two symmetrical support plates 2 are detachably mounted with support rods 3, that is, two support rods 3 are provided. Any support rod 3 is used to support the dropped strip material, and any support rod 3 is arranged parallel to the axial direction of the rotating spindle 1.

[0037] Reference Figure 1 The arrangement of multiple support discs 2 to form a reel allows the strip material to be stably wound on the reel, facilitating the normal operation of winding and unwinding. It also makes it easier for workers to install, disassemble, or maintain the support discs 2. The support rods 3 further support the strip material when it falls off the reel, reducing the possibility of the strip material falling to the ground and affecting the normal operation of winding and unwinding.

[0038] Reference Figure 1 and Figure 2 A drive screw 11 is threaded along the axial direction of the rotating spindle 1, and the rotating spindle 1 and the drive screw 11 are coaxially arranged. A connecting block 12 is welded on the rotating spindle 1. Two sets of connecting blocks 12 are arranged in a circumferential array. Each set of connecting blocks 12 has four blocks, which are arranged at the positions corresponding to the support plate 2.

[0039] Reference Figure 1 Since the four support plates 2 have the same structure and connection method, we will now take one of the support plates 2 as an example for explanation.

[0040] Reference Figure 1 and Figure 2 The support plate 2 includes a connecting plate 21, a fixing block 22, and a plate body 23. Two fixing blocks 22 are arranged at intervals. The side of any fixing block 22 away from the rotating spindle 1 is welded to the plate body 23. Any fixing block 22 is connected to the connecting block 12 through the connecting plate 21. Since any fixing block 22 and the connecting block 12 are connected in the same way, one set will be used as an example for explanation.

[0041] Reference Figure 1 and Figure 2 A first rotating shaft 121 is rotatably connected to the connecting block 12, and a second rotating shaft 221 is rotatably connected to the fixing block 22. The two ends of the first rotating shaft 121 are rotatably connected to the connecting plate 21, and the two ends of the second rotating shaft 221 are rotatably connected to the end of the connecting plate 21 away from the first rotating shaft 121. A sliding block 231 is welded onto the disc body 23. Four sliding blocks 231 are arranged in a circumferential array. Any sliding block 231 slides inside the limiting block, and the sliding direction of any sliding block 231 is arranged radially along the rotating main shaft 1.

[0042] Reference Figure 1 and Figure 2 When the operator operates the drive screw 11 to rotate, the rotating spindle 1 will move on the drive screw 11. Since the limiting block axially limits the sliding block 231, the sliding block 231 can only move radially along the rotating spindle 1. Thus, the rotating spindle 1 drives the connecting plate 21 to swing, and then the connecting plate 21 drives the fixed block 22 and the disc 23 to expand or contract outward to adapt to strip materials of different thicknesses or weights.

[0043] Reference Figure 2 Any support rod 3 is threaded onto the fixing block 22, and any support rod 3 is set perpendicular to the fixing block 22. This detachable connection method makes it easy for workers to install and disassemble the support rod 3, improving the convenience of operation. At the same time, workers can adjust the length of the support rod 3 as needed, improving the flexibility and practicality of the support rod 3.

[0044] Reference Figure 1 A rotating sleeve 111 is fitted on the end of the drive screw 11 away from the rotating spindle 1. The rotating sleeve 111 makes it easier for the operator to turn the drive screw 11, thus improving the convenience of operation.

[0045] The implementation principle of this application embodiment is as follows: when it is necessary to perform winding or unwinding operations on the strip material, the worker connects the support rod 3 to the fixing block 22 by threading. This allows the length of the support rod 3 connected to the fixing block 22 to be adjusted as needed, so that the support rod 3 can support the falling strip material and reduce the possibility of the strip material falling to the ground.

[0046] Example 2:

[0047] The difference between Example 2 and Example 1 is that:

[0048] Reference Figure 3 The fixing block 22 is provided with insertion slots 222 corresponding to the position and number of support rods 3. Any support rod 3 is inserted into the corresponding insertion slot 222. The disc body 23 is provided with limiting bolts 232 for limiting the stop rod 31.

[0049] Reference Figure 3 The support rod 3 and the support plate 2 are connected by a slot 222, which allows the operator to adjust the length of the support rod 3 in the slot 222 as needed. When the length of the support rod 3 is adjusted to the appropriate position, the support rod 3 is limited by tightening the limiting bolt 232, thereby improving the stability of the support rod 3. This connection method not only facilitates installation and disassembly, but also reduces the possibility of the strip material falling to the ground due to loosening during the winding and unwinding process.

[0050] Example 3:

[0051] The difference between Example 3 and Example 1 is that:

[0052] Reference Figure 4 and Figure 5 A stop bar 31 is rotatably connected to one end of any support rod 3 away from the fixed block 22. The stop bar 31 is used to prevent the strip material from falling, further reducing the possibility of the strip material falling to the ground, thus making the use of the winding and unwinding mechanism more convenient and reliable.

[0053] Reference Figure 4 and Figure 5 In this embodiment, any support rod 3 is provided with a rotating pin 32 and an opening slot 33 for avoiding the stop rod 31. The stop rod 31 is rotatably connected to the rotating pin 32. The rotating pin 32 passes through the support rod 3 and the stop rod in the opening slot 33. A locking nut 321 is threadedly connected to the rotating pin 32. The locking nut 321 forms an abutment fit with the side wall of the support rod 3.

[0054] Reference Figure 4 and Figure 5By utilizing the rotatable connection between the stop bar 31 and the rotating pin 32, the operator can adjust the rotation angle of the stop bar 31 as needed to adapt to strip materials of different widths or thicknesses. When the stop bar is adjusted to be horizontal with the support rod 3, the anti-fall space for the strip material is increased, further improving the anti-fall effect of the stop bar 31.

[0055] Reference Figure 4 and Figure 5 The stop lever 31 has a relief slope 311 at one end near the support rod 3 to avoid the support rod 3, which reduces the possibility of wear caused by collision between the stop lever and the support rod 3, thereby allowing the stop lever to rotate smoothly on the rotating pin 32.

[0056] The implementation principle of this application embodiment is as follows: When it is necessary to perform winding or unwinding operations on strip material, the worker first connects the support rod 3 to the fixing block 22 by threading it, and then adjusts the angle of the stop rod 31 on the rotating pin 32 by loosening the locking nut 321. After the stop rod 31 is adjusted to a suitable angle, the locking nut 321 is tightened to limit the position of the stop rod, thereby improving the effect of preventing it from falling.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
