Description

Technical Field

[0001] This invention relates to the technical field of reel switching, and in particular to an I-beam reel switching and feeding device. Background Technology

[0002] In the field of steel cord processing, the I-beam reel serves as the carrier of steel cord. Its wire feeding process is the basis for the continuous supply of materials for subsequent key processes such as calendering, impregnation, or braiding. Traditional wire feeding methods usually use fixed or simple lifting wire feeding frames. When the steel cord on an I-beam reel is used up, the empty reel must be lowered and moved out of the work position manually. Then, a new full reel is hoisted to the wire feeding position, and the wire is threaded, led, and the tension is adjusted. This process not only leads to excessive downtime of the equipment, but also the manual handling and positioning operations are labor-intensive, pose safety hazards, and have low wire changing efficiency, which seriously restricts the overall automation level and capacity efficiency of the production line. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an I-beam reel switching and feeding device, the specific technical solution of which is as follows: The present invention provides a wire reel switching and feeding device, comprising two flipping structures arranged opposite to each other and two clamping structures located between the two flipping structures, wherein the clamping structures are used to fix the wire reel; The flipping structure includes a support arm and a long plate. A long groove is formed on the long plate. The long groove is elongated. A support shaft and a limiting rod are respectively provided on the middle part and the inner wall of the long groove. The limiting rod is fixed to the support arm. A slider is provided on the support shaft and slides vertically on the support arm. The slider and the support arm are connected by an elastic body.

[0004] Furthermore, a power unit is provided on the support arm. The power unit includes a worm gear and a worm that cooperate with each other. The worm gear is mounted on the support shaft via a ratchet, and the worm is vertical and powered by a motor.

[0005] Furthermore, the long plate is composed of a plate body and two splicing bodies. A through groove is provided on the plate body, and two notches are provided opposite each other in the through groove along the length direction of the plate body. The two splicing bodies are slidably disposed in the two notches respectively. The ends of the splicing bodies facing the support shaft are provided with V-shaped baffles. The two V-shaped baffles and the inner sidewall of the through groove form a long groove. The splicing body is connected to the corresponding clamping structure.

[0006] Furthermore, a fixing plate is provided on the plate body, and two connecting arms are rotatably arranged on the fixing plate. A connecting arm is rotatably arranged at the end of the connecting arm, and the connecting arm is connected to the corresponding clamping structure through a connecting sleeve. A secondary disk is coaxially arranged on the fixed disk. The secondary disk moves synchronously with the fixed disk and rotates relative to it. An annular groove is formed on the end face of the secondary disk. The annular groove is located outside the fixed disk and is elliptical in shape. Two sliding pillars are slidably arranged in the annular groove, and each sliding pillar is connected to a corresponding connecting arm.

[0007] Furthermore, the second connecting arm is always located on one side of the straight line where the first connecting arm is located.

[0008] Furthermore, the second connecting arm is a telescopic rod, and its movable end and fixed end are connected by a lock nut.

[0009] Furthermore, a plug shaft is inserted through the middle of the support shaft, and the plug shaft rotates relative to the support shaft. The plug shaft is fixed relative to the slider by a fixing plate, and the sub-disc is mounted on the plug shaft.

[0010] Furthermore, the clamping structure includes two opposing support columns, each of which has a plurality of right-angle clamping plates at its end, and the plurality of right-angle clamping plates are arranged in the circumferential direction of the corresponding support column, and the right-angle clamping plates rotate relative to the support column. A pressure ring is slidably sleeved on the support column, and the pressure ring is connected to the support column by a spring piece. The pressure ring is used to provide lateral thrust for the plurality of right-angle plates. One of the support columns is fixedly connected to the splice body on the corresponding flip structure, and the other support column is connected to the splice body on the corresponding flip structure through a fixing rod. The fixing rod slides relative to the support column on it and is connected by a spring.

[0011] The beneficial effects of this invention are as follows: By using an automatic switching method to replace the wire reel, the operation can be greatly simplified, work efficiency can be improved, and downtime caused by wire reel replacement can be shortened, saving manpower. By using a long slot and a limit rod to restrict the long plate, and combining it with the support shaft that can move vertically, the long plate can be moved down vertically synchronously when it is flipped. This makes it easier to keep the wire reel switching work away from its wire feeding position and reduce the activity space occupied by the switching work. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, an I-beam reel switching and feeding device of the present invention includes two flipping structures 1 arranged opposite to each other and two clamping structures 2 located between the two flipping structures 1, the clamping structures 2 being used to fix the reel; The flipping structure 1 includes a support arm 3 and a long plate 4. A long groove 5 is provided on the long plate 4. The long groove 5 is long and narrow. A support shaft 6 and a limiting rod 7 are respectively provided on the middle part and the inner wall of the long groove 5. The limiting rod 7 is fixed on the support arm 3. A slider 8 is provided on the support shaft 6 and slides vertically on the support arm 3. The slider 8 and the support arm 3 are connected by an elastic body 9.

[0019] Specifically, the two flipping structures 1 are distributed left and right, and the two clamping structures 2 are located between the two flipping structures 1. The two clamping structures 2 are distributed opposite each other on the vertical plane. The clamping structures 2 are connected to the flipping structures 1. The flipping structures 1 can swap the positions of the two clamping structures 2. The clamping structures 2 can be used to fix the I-beam coil. The support arm 3 is used to support the long plate 4. The length direction of the long groove 5 is parallel to the length direction of the long plate 4. That is, the two points on the inner wall of the long groove 5 that are farthest from the center point of the long groove 5 correspond to the length direction of the two long plates 4. Due to the setting of the elastic body 9, the pushing force it provides to the slider 8 can be transmitted to the long plate 4 and the limiting rod 7 through the support shaft 6, so that the limiting rod 7 is close to the inner wall of the long groove 5. After the wire reel on the upper clamping structure 2 completes the wire feeding operation, the support shafts 6 on the two flipping structures 1 are rotated, causing the support shafts 6 to drive the long plate 4 to rotate. Since the limiting rod 7 is fixed on the support arm 3, the limiting rod 7 moves relative to the inner wall of the long groove 5, and the distance between the limiting rod 7 and the support shaft 6 changes. The support shaft 6 drives the slider 8 to slide on the support arm 3, and the long plate 4 moves downward synchronously while rotating. This movement method can easily transfer the upper clamping structure 2 and its upper wire reel downward, avoiding the need to directly rotate the long plate 4 when the axis position of the support shaft 6 is fixed. The upper clamping structure 2 and its upper reel rotate directly, and its movement trajectory occupies a large space in the horizontal direction. When the long plate 4 rotates from the vertical state to the horizontal state, the distance between the limiting rod 7 and the support shaft 6 is the closest. When the support shaft 6 continues to rotate, the distance between the limiting rod 7 and the support shaft 6 gradually increases. At this time, the reels on the two clamping structures 2 complete the switching work, and the new reel is transferred to the wire feeding position by flipping and moving upward in a synchronous motion. The wire feeding reel will switch to the lower side of the flipping structure 1, which makes it convenient for workers to directly replace the wire reel.

[0020] In some embodiments, multiple clamping structures 2 may be provided, and the shape of the long groove 5 may be set as a polygon or other similar shape to facilitate the simultaneous or sequential switching of multiple coils in the working mode.

[0021] By using an automatic switching method to replace the wire reel, the operation can be greatly simplified, work efficiency can be improved, and downtime caused by wire reel replacement can be shortened, saving manpower. By using the long groove 5 and the limit rod 7 to restrict the long plate 4, and by combining the support shaft 6 which can move in the vertical direction, the long plate 4 can be moved down in the vertical direction simultaneously when it is flipped. This makes it easier to keep the wire reel switching work away from its wire feeding position and reduce the activity space occupied by the switching work.

[0022] Furthermore, a power unit is provided on the support arm 3. The power unit includes a worm gear 11 and a worm 12 that work together. The worm gear 11 is mounted on the support shaft 6 via a ratchet 10. The worm 12 is vertical and is powered by a motor 13.

[0023] In its natural state, since the elastic body 9 provides elastic force to the slider 8 and the support shaft 6, this elastic force can be used to keep the support shaft 6 and the limiting rod 7 at their farthest distance. At this time, the long plate 4 is stationary. When the motor 13 drives the worm 12 to rotate, the worm 12 can drive the support shaft 6 to rotate through the worm wheel 11 and the ratchet 10. At this time, the support shaft 6 can drive the long plate 4 to rotate. The limiting rod 7 and the inner wall of the long groove 5 remain in contact. As the support shaft 6 moves in the vertical direction, the support shaft 6 can synchronously drive the worm wheel 11 and the worm 12 to move relative to each other. The worm wheel 11 and the worm 12 maintain a transmission state. When the limiting rod 7 reaches the position closest to the support shaft 6 and continues to move, the support shaft 6 moves in the opposite direction and resets in the vertical direction, thereby achieving the purpose of providing power to the long plate 4.

[0024] It should be noted that when the long plate 4 rotates, its vertical position is mainly restricted by the limiting rod 7. The rotation angle and height of the long plate 4 will affect the position of the worm wheel 11 on the worm 12. Therefore, in order to avoid jamming, the ratchet 10 can be used to connect the support shaft 6 and the worm wheel 11 to ensure the normal operation of the structure.

[0025] Furthermore, the long plate 4 is composed of a plate body 14 and two splicing bodies 15. A through groove 16 is provided on the plate body 14. Two notches 17 are provided opposite each other in the through groove 16 along the length direction of the plate body 14. The two splicing bodies 15 are respectively slidably disposed in the two notches 17. The end of the splicing body 15 facing the support shaft 6 is provided with a V-shaped baffle 18. The two V-shaped baffles 18 and the inner sidewall of the through groove 16 form a long groove 5. The splice body 15 is connected to the corresponding clamping structure 2.

[0026] like Figure 6 As shown, one side of the splice body 15 is located in the through groove 16 on one side of the plate 14 and forms a long groove 5 with the inner wall of the through groove 16. The other side of the splice body 15 is located on the other side of the plate 14 and is connected to the clamping structure 2. When the splice body 15 slides in the notch 17, the size of the long groove 5 formed by the two V-shaped baffles 18 and the inner wall of the through groove 16 changes. That is, the distance between the two points farthest from the support shaft 6 in the long groove 5 changes, thereby changing the vertical displacement of the long plate 4 when it rotates.

[0027] In some embodiments, when the long plate 4 rotates, the splicing body 15 can also actively move toward the support shaft 6, thereby driving the two clamping structures 2 to move closer to each other and increasing the vertical displacement of the upper clamping structure 2 and its upper coil, thereby reducing the space occupied by the switching operation.

[0028] Furthermore, a fixing plate 20 is provided on the plate 14, and two connecting arms 21 are rotatably provided on the fixing plate 20. A connecting arm 22 is rotatably provided at the end of the connecting arm 21, and the connecting arm 22 is connected to the corresponding clamping structure 2 through a connecting sleeve. A secondary disk 32 is coaxially arranged on the fixed disk 20. The secondary disk 32 moves synchronously and rotates relative to the fixed disk 20. An annular groove 23 is provided on the end face of the secondary disk 32. The annular groove 23 is located outside the fixed disk 20 and is elliptical in shape. Two sliding pillars 24 are slidably arranged in the annular groove 23, and each sliding pillar 24 is connected to the corresponding connecting arm 21.

[0029] When the long plate 4 moves and rotates vertically, the fixed plate 20 and the splicing body 15 move synchronously with the long plate 4. The auxiliary plate 32 follows the long plate 4 and moves synchronously in the vertical direction, but the auxiliary plate 32 does not rotate. This causes the auxiliary plate 32 to move relative to the long plate 4. The annular groove 23 on the auxiliary plate 32 also does not rotate. At this time, the fixed plate 20 will push the sliding column 24 to slide in the annular groove 23 through the connecting arm 21. Due to the shape characteristics of the annular groove 23, the distance between the sliding column 24 and the fixed plate 20 will change. The change is that the tilt angle of the connecting arm 21 on the fixed plate 20 changes, thereby causing the connecting arm 21 to pull the splice 15 to slide within the notch 17 through the connecting arm 22, adjusting the distance between the clamping structure 2 and the support shaft 6; when the positions of the two sliding columns 24 are switched, the sliding columns 24 move back to the position farthest from the axis of the support shaft 6 within the annular groove 23. At this time, the connecting arm 21 returns to its initial state on the fixed plate 20, thereby pushing the clamping structure 2 back to the position farthest from the support shaft 6.

[0030] Furthermore, connecting arm 22 is always located on one side of the line where connecting arm 21 is located.

[0031] When connecting arm 22 and connecting arm 21 are collinear, if sliding column 24 slides in annular groove 23 and the distance between sliding column 24 and fixed disk 20 is shortened, then the rotation direction of connecting arm 21 on fixed disk 20 is not fixed. That is, connecting arm 21 can rotate to the left or right on fixed disk 20. At this time, the movement of connecting arm 21 is unrestricted. To avoid this phenomenon, connecting arm 22 can always be located on one side of the line where connecting arm 21 is located, that is, connecting arm 21 and connecting arm 22 are always at an angle. This restricts the movement direction of connecting arm 21 on fixed disk 20.

[0032] Furthermore, connecting arm 22 is a telescopic rod, and its movable end and fixed end are connected by a lock nut.

[0033] To adjust the wire feeding height of clamping structure 2, the length of connecting arm 22 can be adjusted by adjusting the length of the telescopic rod.

[0034] Furthermore, a plug shaft 25 is inserted through the middle of the support shaft 6, and the plug shaft 25 rotates relative to the support shaft 6. The plug shaft 25 is fixed relative to the slider 8 through the fixing plate 26, and the sub-disc 32 is installed on the plug shaft 25.

[0035] Since the secondary disk 32 moves synchronously with the long plate 4 but does not rotate synchronously, the secondary disk 32 can be supported and fixed by the insertion shaft 25 and the fixing plate 26. When the long plate 4 rotates, the support shaft 6, the long plate 4, and the fixing disk 20 will all rotate on the insertion shaft 25. When the long plate 4 moves in the vertical direction, the slider 8 will drive the insertion shaft 25 to move synchronously through the fixing plate 26.

[0036] Furthermore, the clamping structure 2 includes two support columns 27 arranged opposite to each other. Each support column 27 has a plurality of right-angle clamping plates 29 at its end. The plurality of right-angle clamping plates 29 are arranged in the circumferential direction of the corresponding support column 27, and the right-angle clamping plates 29 rotate relative to the support column 27. A pressure ring 28 is slidably sleeved on the support column 27. The pressure ring 28 is connected to the support column 27 by a spring piece 30, and the pressure ring 28 is used to provide lateral thrust for several right-angle clamping plates 29. One support column 27 is fixedly connected to the splice body 15 on the corresponding flip structure 1, and the other support column 27 is connected to the splice body 15 on the corresponding flip structure 1 through the fixing rod 31. The fixing rod 31 slides relative to the support column 27 above it and is connected through the spring 19.

[0037] In its natural state, the thrust provided by the spring 30 to the pressure ring 28 can be transmitted to several right-angle clamping plates 29 at the end of the support column 27, thereby tilting the right-angle clamping plates 29, such as... Figure 8 As shown, the horizontal right-angled sides of the right-angled plates 29 are inclined towards the axis of the support column 27, so that the horizontal right-angled sides of the several right-angled plates 29 on the support column 27 can form a cone shape to facilitate insertion into the center hole of the spool. When it is necessary to fix the spool, slide the support column 27 on the fixing rod 31 away from the other support column 27. At this time, the spring 19 will elastically deform, placing the spool between the two support columns 27. Release the support column 27 on the fixing rod 31, and the spring 19 will support the spool. The thrust generated by the column 27 is transmitted to the spool through several right-angle clamps 29, thereby causing the several right-angle clamps 29 on the two support columns 27 to press against both sides of the spool. The vertical right-angle side of the right-angle clamp 29 contacts the end face of the spool, and the spool pushes the right-angle clamp 29 to rotate. The horizontal right-angle side of the right-angle clamp 29 tilts up in a direction away from the axis of the support column 27 and abuts against the inner wall of the center hole of the spool. Thus, the right-angle clamp 29 is used to achieve a locking and fixing mode for the spool, improving the fastening strength of the spool.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
