Description

Technical Field

[0001] The utility model belongs to the technical field of electric explosion ribbon winding equipment. Specifically, it particularly relates to a wire winding mechanism for automatic ribbon winding. Background Art

[0002] Chinese Patent CN222902650U discloses a split-type electric explosion powder spraying device, in which a tape take-up reel and a tape pay-off reel are arranged in the middle of the mounting plate.

[0003] The input of the ribbon carrying the metal wire in the electric explosion equipment needs to enter from a fixed point, and after the electric explosion is completed, the ribbon needs to be output and collected from a fixed point. However, when the ribbon is wound on the wire reel, due to the certain width of the wire reel, there is a lateral displacement in the winding of the ribbon on the wire reel. When the ribbon is released or wound from the wire reel, it cannot always be released at a position corresponding to the entry point, nor can it always be collected at a position corresponding to the collection point of the electric explosion equipment.

[0004] In addition, the current method of tape feeding and taking-up causes the tape feeding and taking-up speeds to be asynchronous.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related art, the utility model proposes a wire winding mechanism for automatic ribbon winding to overcome the above technical problems existing in the existing related art.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a wire winding mechanism for automatic ribbon winding, including a mounting bracket for mounting on an electric explosion cavity. A rotatable explosion disc is also arranged on the electric explosion cavity. The upper end and the lower end of the mounting bracket are respectively fixedly connected with a bidirectional screw rod and a sliding rod. A turning boss is fixedly arranged in the middle of the bidirectional screw rod. There are unthreaded areas at both ends of the bidirectional screw rod, and a lead screw support cylinder is sleeved in this area. The inner side of the lead screw support cylinder is hinged to the middle of a swing rod. The two ends of the swing rod are respectively used for thread engagement with the two ends of the bidirectional screw rod. The two ends of the swing rod are connected to the lead screw support cylinder through spring ejectors. One end of a displacement maintaining component and a wire storage reel are fixedly installed at one end of the lead screw support cylinder. The other end of the displacement maintaining component is fixedly installed on a bushing, and the bushing is sleeved on the sliding rod;

[0009] A wire winding disc is also sleeved on the bushing. The lead screw support cylinder and the bushing are power-connected through a linkage component, and the linkage component realizes power transmission through a friction component arranged between it and the wire winding disc. The friction component is sleeved on the bushing, and the explosion disc drives the wire storage disc to rotate through a carrier tape.

[0010] Further, the swing rod includes a base frame. The middle of the base frame is hinged on the lead screw support cylinder. Left-handed nuts and right-handed nuts that can be threadedly engaged with the corresponding ends of the bidirectional screw are respectively arranged at both ends of the base frame. The thread directions at both ends of the bidirectional screw are opposite. Blocking blocks are symmetrically arranged on the lower surface of the base frame, and the two blocking blocks are in a V shape.

[0011] Further, the spring ejector pin includes an ejector cylinder. There is a cavity in the ejector cylinder. A ejector rod is slidably installed in the cavity. A clamping spring is fixedly installed on the end face of one end of the ejector rod located in the cavity, and the other end of the clamping spring is fixedly installed on the bottom of the cavity. The ends of the ejector rod and the ejector cylinder away from each other are both hemispherical.

[0012] Hemispherical grooves are respectively formed on the inner wall of the lead screw support cylinder and the base frame for fitting with the hemispherical ends of the ejector rod and the ejector cylinder respectively.

[0013] Further, the displacement maintaining component includes a bearing fixing plate. A passive bearing and an active bearing are fixedly embedded on the bearing fixing plate. The inner ring of the passive bearing is fixedly installed on the outer periphery of the bushing, and the inner ring of the active bearing is fixedly installed on the outer periphery of the lead screw support cylinder.

[0014] Further, the linkage component includes an active synchronous pulley and a passive synchronous pulley. The active synchronous pulley penetrates and is fixed on the lead screw support cylinder, and the passive synchronous pulley is fixedly installed on the bushing. The active synchronous pulley and the passive synchronous pulley are power-connected through a synchronous belt.

[0015] Further, the friction component includes two friction plates. Guide holes are respectively formed on the sides of the two friction plates close to each other.

[0016] Further, the friction plate is made of rubber material.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model drives the wire storage disk to rotate through an explosion disk, drives the lead screw support cylinder to rotate, and the spring ejector pin makes the left-handed nut and the right-handed nut on the base frame alternately engage with the bidirectional screw, prompting the lead screw support cylinder to generate left and right reciprocating displacements while rotating, enabling the wire storage disk to move left and right while rotating and releasing wire, keeping the wire release point always aligned with the explosion disk feed point, and the linkage assembly and the displacement maintaining assembly synchronously drive the wire take-up disk to rotate and move left and right, ensuring that the wire take-up point always corresponds to the explosion disk discharge point, thereby improving the stability of the continuous electric explosion process of the explosion disk.

[0019] 2. In the utility model, the driven synchronous pulley and the friction plate are in frictional transmission to make the bushing rotate. The wire storage disk starts in a state of being filled with the carrier tape containing metal wire, and the wire take-up disk is in an empty state. The rotation radii of the two are quite different. Due to the small transmission ratio between the driving synchronous pulley and the driven synchronous pulley, the rotation speed of the wire take-up disk is faster than that of the wire storage disk, so that the wire feeding speed and the wire take-up speed are kept consistent. As the carrier tape containing metal wire in the wire storage disk decreases and the carrier tape of the wire take-up disk increases, the frictional transmission of the friction plate is used to maintain the consistency of the wire release speed and the wire take-up speed.

[0020] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the utility model.

[0030] Please refer to Figures 1 - 4 As shown, the present utility model is a wire winding mechanism for automatic tape winding, including a mounting bracket 1, which is used to be mounted on the electric explosion cavity. A rotatable explosion disk 13 is also provided on the electric explosion cavity. (The mounting bracket 1 is mounted on the mounting plate in Chinese Patent CN222902650U, and the explosion disk 13 is the explosion device in this patent). The upper end and the lower end of the mounting bracket 1 are respectively fixedly connected with a bi-directional screw 2 and a slide bar 3. A flipping boss 4 is fixedly arranged in the middle of the bi-directional screw 2. There are unthreaded areas at both ends of the bi-directional screw 2, and a screw support cylinder 15 is sleeved in this area. The inner side of the screw support cylinder 15 is hinged to the middle of a swing rod 5. The two ends of the swing rod 5 are respectively used for thread engagement with the two ends of the bi-directional screw 2. The two ends of the swing rod 5 are connected to the screw support cylinder 15 through spring ejector pins 6. One end of the screw support cylinder 15 is fixedly installed with one end of a displacement maintaining assembly 7 and a wire storage disk 8. The other end of the displacement maintaining assembly 7 is fixedly installed on a bush 9, and the bush 9 is sleeved on the slide bar 3.

[0031] The thread directions at both ends of the bidirectional screw 2 are opposite.

[0032] A wire take-up disc 10 is also sleeved on the bushing 9. The lead screw support cylinder 15 and the bushing 9 are power-connected through a linkage assembly 11. And the linkage assembly 11 realizes power transmission through a friction assembly 12 arranged between it and the wire take-up disc 10. And the friction assembly 12 is sleeved on the bushing 9. The explosion disc 13 drives the wire storage disc 8 to rotate through a load-carrying belt 14.

[0033] The wire storage disc 8 and the wire take-up disc 10 are respectively the tape release disc and the tape take-up disc in Chinese Patent CN222902650U.

[0034] The swing rod 5 includes a base frame 501. The middle of the base frame 501 is hinged on the lead screw support cylinder 15. A left-handed nut 502 and a right-handed nut 503 that can mesh with the corresponding threads at both ends of the bidirectional screw 2 are respectively arranged at both ends of the base frame 501. Block pieces 504 are symmetrically arranged on the lower surface of the base frame. The two block pieces 504 are in an inverted V shape.

[0035] During use, the explosion disc 13 drives the wire storage disc 8 to rotate through the load-carrying belt 14. Since the wire storage disc 8 is fixedly installed on the lead screw support cylinder 15, when the wire storage disc 8 rotates, it can drive the lead screw support cylinder 15 to rotate. And because the base frame 501 is eccentrically clamped on the lead screw support cylinder 15 through a spring ejector pin 6, when the lead screw support cylinder 15 rotates, it synchronously drives the base frame 501 to rotate around the concentrically arranged bidirectional screw 2. Among the left-handed nut 502 and the right-handed nut 503 on the base frame 501, under the action of the spring ejector pin 6, one of them always meshes with one end of the corresponding bidirectional screw 2;

[0036] Taking the meshing of the left-handed screw nut 502 and the bidirectional screw 2 as an example for elaboration, when the two are meshed, as the screw support cylinder 15 drives the base frame 501 to rotate around the bidirectional screw 2, since the left-handed screw nut 502 on the base frame 501 meshes with the bidirectional screw 2 fixedly installed on the mounting bracket 1, it prompts the left-handed screw nut 502 to move to the right by using thread meshing while rotating around the bidirectional screw 2. And the base frame 501 where the left-handed screw nut 502 is located is on the screw support cylinder 15, so that the screw support cylinder 15 also synchronously moves to the right. As the screw support cylinder 15 moves to the right, the stop block 504 on the left side of the base frame 501 gradually approaches the flipping boss 4. When the stop block 504 on the left side of the base frame 501 starts to squeeze the flipping boss, the left-handed screw nut 502 at the left end of the base frame 501 separates from the bidirectional screw 2. At the same time, under the action of the spring ejector pin 6, the right-handed screw nut 503 meshes with the other end of the bidirectional screw 2. As the screw support cylinder 15 rotates, it prompts the right-handed screw nut 503 to move to the left while rotating around the bidirectional screw 2, so that the screw support cylinder 15 also synchronously moves to the left until the stop block 504 on the right side of the base frame 501 starts to squeeze the flipping boss, the right-handed screw nut 503 at the right end of the base frame 501 separates from the bidirectional screw 2, and the left-handed screw nut 502 meshes with the bidirectional screw 2 again. Repeating the above process realizes the left and right reciprocating motion of the screw support cylinder 15, so that the screw support cylinder 15 synchronously drives the wire storage disk 8 to move left and right while rotating and releasing the carrier tape 14, so that the position where the wire storage disk 8 releases the carrier tape 14 always corresponds to the feeding point of the explosion disk 13.

[0037] When the screw support cylinder 15 rotates, the screw support cylinder 15 drives the operation of one end of the linkage component 11 located on the shaft sleeve 9. A wire winding disk 10 is rotatably installed on the shaft sleeve 9, and a friction component 12 is sleeved on the outer surface of the shaft sleeve 9. When one end of the linkage component 11 located on the shaft sleeve 9 operates, the linkage component 11 drives the wire winding disk 10 to rotate through the friction component 12;

[0038] At the same time, when the screw support cylinder 15 moves left and right, the displacement maintaining component 7 makes the screw support cylinder 15 and the shaft sleeve 9 maintain synchronous displacement, so that the wire winding disk 10 can move left and right while rotating to wind the carrier tape 14 passing through the explosion disk 13, and the position where the wire winding disk 10 winds the carrier tape 14 passing through the explosion disk 13 always corresponds to the discharging point of the explosion disk 13.

[0039] Among them, the linkage component 11 is mainly used to make the screw support cylinder 15 and the shaft sleeve 9 operate synchronously, and the friction component 12 is used to realize the power transmission between the linkage component 11 and the wire winding disk 10.

[0040] The above-mentioned feeding point and discharging point respectively refer to the tape inlet and tape outlet of the carrier tape in the explosion disk 13.

[0041] In this application, the wire storage disk 8 is driven to rotate by the explosion disk 13, driving the lead screw support cylinder 15 to rotate. The spring ejector pin causes the left-handed nut 502 and the right-handed nut 503 on the base frame to alternately engage with the bidirectional screw 2, prompting the lead screw support cylinder 15 to generate left and right reciprocating displacements while rotating, enabling the wire storage disk 8 to move left and right while rotating and releasing wire, keeping its wire release point always aligned with the explosion disk feed point. The linkage assembly and the displacement maintaining assembly synchronously drive the wire take-up disk to rotate and move left and right, ensuring that its wire take-up point always corresponds to the explosion disk discharge point, thereby improving the stability of the continuous electric explosion process of the explosion disk.

[0042] In one embodiment, for the above-mentioned spring ejector pin 6, the spring ejector pin 6 includes a top cylinder 601. The top cylinder 601 has a cavity, and a top rod 602 is slidably installed in the cavity. A clamping spring 603 is fixedly installed at one end face of the top rod 602 located in the cavity, and the other end of the clamping spring 603 is fixedly installed at the bottom of the cavity. Both ends of the top rod 602 and the top cylinder 601 away from each other are hemispherical.

[0043] Hemispherical grooves are respectively formed on the inner wall of the lead screw support cylinder 15 and the base frame 501, and are respectively used to fit with the hemispherical ends of the top rod 602 and the top cylinder 601.

[0044] In specific applications, both clamping springs 603 are in a compressed state and have an initial elastic force. Under the action of the clamping springs 603 at both ends, the base frame 501 has only two states, namely, higher on the left and lower on the right, and higher on the right and lower on the left.

[0045] When it is higher on the left and lower on the right: the right-handed nut 503 engages with the bidirectional screw 2. The clamping spring on the left side of the base frame 501 is further compressed, and the clamping spring on the right side is released but still in a compressed state, and the base frame 501 moves to the left.

[0046] When it is higher on the right and lower on the left, the left-handed nut 502 engages with the bidirectional screw 2. The clamping spring on the right side of the base frame 501 is further compressed, and the clamping spring on the left side is released but still in a compressed state, and the base frame 501 moves to the right.

[0047] How the spring ejector pin 6 enables the left-handed nut 502 and the right-handed nut 503 to alternately engage with the bidirectional screw 2 will be described below by taking the engagement of the left-handed nut 502 and the bidirectional screw 2 in the initial state as an example:

[0048] The thread directions at both ends of the bidirectional screw 2 are opposite, and the left-handed nut 502 and the right-handed nut 503 correspond to one end of their respective bidirectional screws 2.

[0049] Specifically:

[0050] When the lead screw support cylinder 15 rotates, since the middle part of the base frame 501 is hinged to the lead screw support cylinder 15, the base frame 501 will be synchronously driven to rotate around the double lead screw 2 with it. At this time, the left-handed nut 502 meshes with the double lead screw 2, and the double lead screw 2 is fixed differently. Therefore, while the base frame 501 rotates around the double lead screw 2, it slides to the right relative to the double lead screw 2, so that the base frame 501 drives the lead screw support cylinder 15 to move to the right;

[0051] As the base frame 501 continues to move to the right, when the stop block 504 on the left side of the base frame 501 presses against the flipping boss and the left-handed nut 502 on the left side of the base frame 501 rotates upward beyond the horizontal line (parallel to the central axis of the double lead screw 2 and passing through the hinge point of the base frame 501), at this time, the clamping springs in the left and right spring ejectors 6 are quickly released. While the left-handed nut 502 is quickly separated from the double lead screw 2, the right-handed nut 503 is quickly meshed with the double lead screw 2. While the lead screw support cylinder 15 rotates, under the action of the right-handed nut 503 and the double lead screw 2, it moves to the left. By repeating the above steps, the lead screw support cylinder 15 makes a reciprocating movement of moving left and right while rotating.

[0052] In one embodiment, for the above displacement maintaining assembly 7, the displacement maintaining assembly 7 includes a bearing fixing plate 701, and a passive bearing 702 and an active bearing 703 are fixedly embedded on the bearing fixing plate 701. The inner ring of the passive bearing 702 is fixedly installed on the outer periphery of the shaft sleeve 9, and the inner ring of the active bearing 703 is fixedly installed on the outer periphery of the lead screw support cylinder 15;

[0053] Through the action of the bearing fixing plate 701, the passive bearing 702 and the active bearing 703, the lead screw support cylinder 15 and the shaft sleeve 9 can achieve synchronous left and right displacement while rotating respectively, so that the wire storage disc 8 and the wire take-up disc 10 always remain corresponding, so that the release of the load ribbon on the wire storage disc 8 corresponds to the load ribbon that has been electrically exploded on the wire take-up disc 10.

[0054] In one embodiment, for the above linkage assembly 11, the linkage assembly 11 includes an active synchronous pulley 1101 and a passive synchronous pulley 1102. The active synchronous pulley 1101 passes through and is fixed on the lead screw support cylinder 15, and the passive synchronous pulley 1102 is fixedly installed on the shaft sleeve 9. The active synchronous pulley 1101 and the passive synchronous pulley 1102 are power-connected by a synchronous belt 1103;

[0055] When the lead screw support cylinder 15 rotates, the active synchronous pulley 1101 fixedly installed on the lead screw support cylinder 15 drives the passive synchronous pulley 1102 to rotate by using the synchronous belt 1103, and then the passive synchronous pulley 1102 drives the shaft sleeve 9 to rotate.

[0056] In addition, the driving synchronous pulley 1101 and the driven synchronous pulley 1102 are provided with teeth on their surfaces, and the synchronous belt 1103 is also selected to be adapted thereto, so as to increase the transmission force between the driving synchronous pulley 1101, the driven synchronous pulley 1102 and the synchronous belt 1103.

[0057] In one embodiment, for the above-mentioned friction assembly 12, the friction assembly 12 includes two friction plates 1201. Guide holes are formed on one side of the two friction plates 1201 close to each other. The guide holes of the two correspond to each other one by one, and the same guide rod 1202 is arranged in the corresponding guide holes. A friction spring 1203 is arranged between the friction plates 1201. Two ends of the friction spring 1203 are respectively fixed on the surfaces of the corresponding friction plates 1201. One sides of the two friction plates 1201 away from each other are respectively attached to the side surfaces of the driven synchronous pulley 1102 and the wire take-up reel 10. The friction plates 1201 are made of rubber material;

[0058] The friction spring 1203 always keeps a compressed state, so that the friction plates 1201 connected at both ends are closely attached to the driven synchronous pulley 1102 and the wire take-up reel 10 and maintain a certain pressure, so as to ensure the frictional force between the friction plates 1201 and the driven synchronous pulley 1102 and the wire take-up reel 10. When the driven synchronous pulley 1102 rotates, the wire take-up reel 10 can be driven to rotate through the friction plates 1201 and the guide rod 1202.

[0059] In addition, when starting to operate, the rotational linear velocity v of the explosion disc 13 is constant, v = 2πrn; n is the rotational speed, 2π is a constant, representing the radian value corresponding to each rotation. r is the winding radius of the carrier tape (the carrier radii D and d on the wire storage reel 8 and the wire take-up reel 10)

[0060] The wire storage reel 8 is in a full-load state, and the carrier radius in the full-load state is D;

[0061] The wire take-up reel 10 is in an empty-load state with a radius of d. Since the wire feeding speed and the wire taking-up speed are the same, the minimum speed ratio i = D / d required to ensure the tension of the carrier tape during the entire feeding and discharging process of the electric explosion is obtained, and thus the sizes of the driving synchronous belt pulley and the driven synchronous belt pulley are designed.

[0062] Friction transmission always exists between the driven synchronous pulley 1102 and the friction plates 1201, which is sliding friction. As the electric explosion process of the metal wire on the carrier tape 14 by the explosion disc 13 proceeds, the number of winding layers of the wire take-up reel 10 becomes more and more. Since v is constant, n (the winding radius of the carrier tape on the wire storage reel 8) decreases, and the rotational speed of the wire take-up reel 10 becomes slower, and the wire taking-up speed is kept constant through sliding friction.

[0063] Furthermore, the passive synchronous pulley 1102 and the friction plate 1201 cause the sleeve 9 to rotate through frictional transmission. The wire storage disc 8 initially is in a state of being filled with the carrier tape 14 containing the wire, and the wire take-up disc 10 is in an empty state. The rotational radii of the two are quite different. Since the transmission ratio of the active synchronous pulley 1101 and the passive synchronous pulley 1102 is small, the rotational speed of the wire take-up disc 10 is faster than that of the wire storage disc 8, so that the wire feeding speed and the wire take-up speed are kept consistent. As the carrier tape containing the wire on the wire storage disc 8 decreases and the carrier tape on the wire take-up disc 10 increases, the frictional transmission of the friction plate 1201 is used to maintain the consistency of the wire releasing speed and the wire take-up speed.
