Description

Technical Field

[0001] This invention relates to the field of emulsion explosive packaging technology, specifically to a timing device for an emulsion explosive loading machine. Background Technology

[0002] Existing emulsion explosives often use snap-fit ​​sealing, which requires a snap-fit ​​device during the snap-fit ​​formation process. In these devices, the metal wire is typically first shaped into a U-shape, and then the U-shaped wire is compressed using a spinning or extrusion mechanism to complete the snap-fit. Furthermore, existing devices usually only form one snap-fit ​​structure. To improve sealing, sometimes the snap-fit ​​device forms two parallel snap-fit ​​structures with no overlap, resulting in a lack of interaction between the two structures. Summary of the Invention

[0003] The purpose of this invention is to provide a clipping device for an emulsion explosive loading machine, which facilitates subsequent forming into two clip structures, and enables one clip to cover the outside of the other clip, thereby improving the sealing performance of the explosive roll.

[0005] The second bending forming plate is arranged parallel to the first bending forming plate, and the second bending forming plate can be made perpendicular to the feeding direction of the drug roll through a rotating mechanism.

[0006] The frame is equipped with a forming mechanism, and the forming mechanism is equipped with a pressure head.

[0007] The forming mechanism is used to drive the pressure head to move downward and can cooperate with the first bending forming plate and the second bending forming plate.

[0008] The bottom of the pressure head is provided with an arc surface, and the axis of the arc surface is parallel to the feeding direction of the drug roll.

[0009] The frame is provided with a first lifting mechanism, which is used to lift the first bending and forming plate.

[0010] The rotating mechanism is provided with a second lifting mechanism, which is used to lift the second bending and forming plate.

[0011] The frame is provided with a support base, and the support base is provided with two wire feeding channels. The two wire feeding channels are used to cooperate with an external wire feeding device and to feed two metal wires to the top of the first bending forming plate and the second bending forming plate, respectively.

[0012] The support base is equipped with a wire cutting mechanism, which is used to cut the metal wire.

[0013] Furthermore, both the first bending forming plate and the second bending forming plate have an arc-shaped structure. Two limiting pins are respectively provided at the end of the first bending forming plate and the second bending forming plate near the support base. The limiting pins are used to limit the metal wire.

[0014] Furthermore, the rotating mechanism includes a rotary cylinder disposed inside the frame and a rotating shaft rotatably disposed on the frame.

[0015] A rotating block is fitted around the outside of the rotating shaft, and the second lifting mechanism is mounted on the rotating block.

[0016] Furthermore, the second lifting mechanism includes a second support frame disposed on the rotating block, and a second moving rod is movably disposed on the second support frame.

[0017] The second moving rod is connected to the second bending forming plate, and a second baffle is provided on the second moving rod.

[0018] The second support frame is equipped with a second lifting cylinder, and the output end of the second lifting cylinder is connected to a second baffle.

[0019] Furthermore, the first lifting mechanism includes a first support frame mounted on the frame, and a first moving rod is movably mounted on the first support frame.

[0020] The first movable rod is connected to the first bent forming plate, and a first baffle is provided on the first movable rod.

[0021] The first support frame is equipped with a first lifting cylinder, and the output end of the first lifting cylinder is connected to a first baffle.

[0022] Furthermore, the forming mechanism includes a pressing cylinder mounted on the frame, the output end of which is connected to a pressing head.

[0023] Furthermore, the wire cutting mechanism includes a wire cutting motor and a nut seat, the nut seat being movably mounted on a support base.

[0024] The wire cutting motor is mounted on a support base, and the output end of the wire cutting motor is connected to a first lead screw.

[0025] The first lead screw is rotatably mounted on the support base, and the first lead screw is connected to the nut seat by a threaded connection.

[0026] A cutter cylinder is provided on the nut seat, and the output end of the cutter cylinder is connected to a cutter holder, in which a cutter is installed.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows.

[0028] 1. In the initial state, the first bending forming plate and the second bending forming plate are set in parallel, and the two metal wires can be fed synchronously without interfering with each other. At the same time, it is convenient for the wire cutting mechanism to cut the two metal wires at the same time.

[0029] 2. The first bending forming plate is at a certain angle to the feeding direction of the drug roll, and the axis of the bottom arc surface of the pressure head is parallel to the feeding direction of the drug roll. When the first bending forming plate is in conjunction with the pressure head, the metal wire is bent into a U-shape and the two ends are staggered. At the same time, by providing a rotating mechanism, the second bending forming plate can be made perpendicular to the feeding direction of the drug roll. Thus, when the second bending forming plate is in conjunction with the pressure head, the metal wire on the second bending forming plate is bent so that the two bent metal wires have overlapping and intersecting parts.

[0030] 3. It facilitates the formation of two snaps under the action of a spinning or pressing snapping mechanism, with one snap covering part of the other snap, improving the sealing of the medicine roll. The material adjacent to the covered snap increases the difficulty of the snap detaching from the medicine roll. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-9 The present invention provides a technical solution: a clamping device for an emulsion explosive loading machine, comprising a frame 1, wherein a first lifting mechanism 5 and a rotating mechanism 6 are arranged inside the frame 1, and a second lifting mechanism 9 is arranged on the rotating mechanism 6; a first bending forming plate 7 is arranged on the first lifting mechanism 5, and a second bending forming plate 8 is arranged on the second lifting mechanism 9; the first bending forming plate 7 is at a certain angle to the feed direction of the explosive roll, specifically 50-70 degrees; initially, the second bending forming plate 8 is arranged parallel to the first bending forming plate 7, and the rotating mechanism 6 can drive the second bending forming plate 8 to be perpendicular to the feed direction of the explosive roll.

[0044] A forming mechanism 2 is provided on the frame 1, and a pressure head 3 is provided on the forming mechanism 2. The forming mechanism 2 is used to drive the pressure head 3 to move downward, and the pressure head 3 cooperates with the first bending forming plate 7 and the second bending forming plate 8. Specifically, the first bending forming plate 7 and the second bending forming plate 8 are both arc-shaped, and edge plates 71 are also provided on both sides of the first bending forming plate 7 and the second bending forming plate 8. The bottom of the pressure head 3 is provided with an arc surface 31, and the axis of the arc surface 31 is parallel to the feeding direction of the drug roll. The pressure head 3 is pressed down by the forming mechanism 2, and the first bending forming plate 7 is lifted by the first lifting mechanism 5, and the second bending forming plate 8 is lifted by the second lifting mechanism 9, so that the pressure head 3 can cooperate with the first bending forming plate 7 and the second bending forming plate 8.

[0045] The forming mechanism 2 includes a pressing cylinder 21 mounted on the frame 1, and the output end of the pressing cylinder 21 is connected to the pressing head 3.

[0046] The frame 1 is provided with a support base 4, and the support base 4 is provided with two wire feeding channels 42. The two wire feeding channels 42 are used to cooperate with external wire feeding devices, wire feeding devices, etc., to feed two metal wires to the first bending forming plate 7 and the second bending forming plate 8 respectively. Since the first bending forming plate 7 and the second bending forming plate 8 are arranged in parallel in the initial state, the two metal wires can be fed synchronously without interfering with each other.

[0047] Meanwhile, the first bending forming plate 7 and the second bending forming plate 8 correspond to the two wire feeding channels 42 respectively, and two limiting pins 10 are provided at the end of the first bending forming plate 7 and the second bending forming plate 8 near the support base 4. The limiting pins 10 are used to limit the metal wire, that is, one of the metal wires conveyed by the wire feeding channel 42 can just pass through the two limiting pins 10 at the end of the first bending forming plate 7, and the other metal wire can just pass through the two limiting pins 10 at the end of the second bending forming plate 8. In addition, before being conveyed and cut, the two metal wires are close to the ends of the first bending forming plate 7 and the second bending forming plate 8. When the metal wires are cut, the two metal wires are just supported and limited by the first bending forming plate 7 and the second bending forming plate 8. In order to improve the support effect of the metal wires, a groove structure for matching the metal wires can be provided in the movable part of the first bending forming plate 7 and the second bending forming plate 8 where there are no limiting pins 10.

[0048] A wire cutting mechanism 41 is provided on the support base 4. The wire cutting mechanism 41 is used to cut metal wire. The wire cutting mechanism 41 includes a nut seat 411 movably disposed on the support base 4. Specifically, the nut seat 411 and the support base 4 are connected by a slider-groove structure. That is, the support base 4 is provided with a groove, and the nut seat 411 is provided with a slider. The slider and the groove cooperate to realize that the nut seat 411 can move in the horizontal direction. A first lead screw 412 is threadedly engaged in the nut seat 411. The first lead screw 412 is movably disposed on the support base 4 through a bearing, and one end of the first lead screw 412 is connected to the output end of the wire cutting motor 413, which is mounted on the support base 4. A cutting cylinder 414 is installed vertically, and the output end of the cutting cylinder 414 is connected to a cutting base 415, in which a cutting blade 416 is installed. The first lead screw 412 is rotated by the wire cutting motor 413, which in turn drives the nut seat 411 to move closer to the first bending forming plate 7. After moving to the appropriate position, the output end of the cutting cylinder 414 moves down and drives the cutting base 415 and the cutting blade 416 down, while cutting the two metal wires. During the cutting process, the two sides of the cutting blade 416 guide the metal wire to a certain extent, so that there is a certain gap between the two parts of the metal wire being cut, in order to avoid interfering with the subsequent bending or movement of the metal wire.

[0049] The first lifting mechanism 5 includes a first support frame 51 mounted on the frame 1, and a first moving rod 52 movably mounted on the first support frame 51. Specifically, a sliding groove can be provided on the first support frame 51, and the first moving rod 52 is connected to a slider. The movement of the first moving rod 52 is achieved through the cooperation of the slider and the sliding groove. The first moving rod 52 is connected to the first bending forming plate 7, and a first baffle 54 is provided on the first moving rod 52. A first lifting cylinder 53 is mounted on the first support frame 51, and the output end of the first lifting cylinder 53 is connected to the first baffle 54. The first lifting cylinder 53 can drive the first baffle. 54 moves upward, thereby causing the first bending forming plate 7 to move upward and approach the pressure head 3. The pressure head 3 is then pressed down by the pressure cylinder 21. The first lifting cylinder 53 moves the first bending forming plate 7 upward, and the pressure cylinder 21 moves the pressure head 3 downward. The pressure head 3 cooperates with the first bending forming plate 7, thereby bending the cut metal wire on the first bending forming plate 7 into a U-shape. Since the first bending forming plate 7 is at a certain angle to the feed direction of the drug roll, and the axis of the bottom arc surface 31 of the pressure head 3 is parallel to the feed direction of the drug roll, the two ends of the metal wire bent into a U-shape are staggered. Figure 8 The state shown.

[0050] The rotating mechanism 6 includes a rotating cylinder 61 disposed inside the frame 1. The output end of the rotating cylinder 61 is connected to a rotating shaft 62, which is movably mounted on the frame 1 via bearings. A rotating block 63 is sleeved on the outside of the rotating shaft 62, and the second lifting mechanism 9 is disposed on the rotating block 63.

[0051] The second lifting mechanism 9 includes a second support frame 91 mounted on the rotating block 63, and a second moving rod 92 movably mounted on the second support frame 91. Similarly, a sliding groove can be provided on the second support frame 91, and the second moving rod 92 is connected to a slider. The movement of the second moving rod 92 is achieved through the cooperation of the slider and the sliding groove. Alternatively, a linear slide rail can be connected between the second support frame 91 and the second moving rod 92. The second moving rod 92 is connected to the second bending forming plate 8, and a second baffle 94 is provided on the second moving rod 92. A second lifting cylinder 93 is mounted on the second support frame 91, and the output end of the second lifting cylinder 93 is connected to the second baffle 94. The second lifting cylinder 93 can drive the second baffle 94 to move upward, thereby driving the first bending forming plate 7 to move upward and closer to the pressure head 3.

[0052] When bending the metal wire on the second bending forming plate 8, the operation is performed after the metal wire on the first bending forming plate 7 has been bent. During operation, firstly, the rotating cylinder 61 drives the rotating shaft 62 and the rotating block 63 to rotate, so that the second bending forming plate 8 is perpendicular to the feeding direction of the drug cartridge. Then, the second lifting cylinder 93 drives the second bending forming plate 8 to move upward. Since the pressure head 3 has moved downward when bending the metal wire on the first bending forming plate 7, the upward-moving second bending forming plate 8 brings the metal wire on it close to the pressure head 3. With the cooperation of the pressure head 3 and the second bending forming plate 8, the metal wire on the second bending forming plate 8 is bent into a U-shape. Since the metal wire is bent later, and the two ends of the metal wire on the first bending forming plate 7 are staggered, a part of the metal wire can cover the outside of a part of the previous metal wire. That is, the two bent metal wires have overlapping and intersecting parts, such as... Figure 9 As shown; then, with the help of an external spinning or pressing buckle mechanism, the two U-shaped metal wires are easily clipped together to form two buckles, with one buckle covering part of the other buckle, as shown. Figure 9 As shown, this improves the sealing of the drug roll seal, and the material adjacent to the covered buckle increases the difficulty of the buckle detaching from the drug roll.

[0053] Working principle: This clipping device is used to clip the thinned end of the medicine roll. During operation, metal wires are first fed through two wire feeding channels 42, and the first drive motor 25 drives the first lead screw 412 to rotate, thereby moving the nut seat 411 closer to the first bending forming plate 7. After reaching the set position, the output end of the cutter cylinder 414 moves downward, causing the cutter seat 415 and cutter 416 to move downward, simultaneously cutting the two metal wires. The two cut metal wires are just supported and limited by the first bending forming plate 7 and the second bending forming plate 8. Then, the first lifting cylinder 53 drives the first bending forming plate 7 upward, and the pressing head 3 moves downward under the action of the pressing cylinder 21. The pressing head 3 cooperates with the first bending forming plate 7 to bend the cut metal wires on the first bending forming plate 7 into a U-shape, with the two ends of the U-shaped metal wire staggered. Afterward, the rotating cylinder 61 drives the rotating shaft 62 and rotating block 63 to rotate, driving the first... The second bending forming plate 8 is perpendicular to the feeding direction of the medicine roll. The second lifting cylinder 93 drives the second bending forming plate 8 to move upward. Since the pressure head 3 has moved down when bending the metal wire on the first bending forming plate 7, the upward-moving second bending forming plate 8 drives the metal wire on it to come close to the pressure head 3. With the cooperation of the pressure head 3 and the second bending forming plate 8, the metal wire on the second bending forming plate 8 is bent into a U-shape. Since the metal wire is bent later and the two ends of the metal wire on the first bending forming plate 7 are staggered, a part of the metal wire can cover the outside of a part of the front metal wire. That is, the two bent metal wires have an overlapping and crossing part. This facilitates the use of an external rotary snap-fit ​​device or mechanism to easily snap the two U-shaped metal wires into two snap-fit ​​structures, with one snap-fit ​​covering the outside of the other. Since two snap-fits are formed, with one snap-fit ​​covering a part of the other snap-fit, the sealing performance of the medicine roll can be improved.
