Description

Technical Field

[0001] The invention relates to the technical field of fireworks inserting and drawing equipment, in particular to a firecracker inserting and drawing device. Background Art

[0002] The process of punching holes and inserting firework paper tubes has always been a very important production process in the production of fireworks. Today's fireworks assembling equipment mainly assembles multiple fireworks paper tubes. Among the fireworks assembling equipment, inserting firework paper tubes is the key process of fireworks assembling. In order to improve the efficiency of inserting firework paper tubes, fireworks inserting and inserting machines are widely used in the production process of fireworks.

[0003] According to a disclosed colorful chrysanthemum fireworks insertion and drawing device (publication number: CN217844928U), in the above application, the rotation of the screw rod is driven by a servo motor, the movement of the connecting block is driven by the rotation of the screw rod, and the reciprocating movement of the connecting block is used to drive the lead mold disk to move to a specified insertion and drawing position. At the same time, the lead mold disk is controlled to rotate by a servo motor, which facilitates the automatic resetting and insertion of the lead mold disk, and effectively improves the efficiency of fireworks insertion and drawing.

[0004] However, in actual use of the above-mentioned equipment, when the cutter cuts the lead wire, it moves forward to cut the lead wire. After cutting, the cutter needs to move backward to reset, and then the lead wire can be transmitted down before the electric slide rail with the cutter can be started again to move and cut again. In this process, the reset procedure of the cutter delays the lead feeding time and also causes a waste of some mechanical energy. In view of this, we propose a firecracker insertion device. Summary of the invention

[0005] The object of the present invention is to provide a firecracker inserting device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a firecracker insertion and guiding device, comprising a workbench, a lead mold plate is arranged at the front end of the upper surface of the workbench, a frame is fixedly installed at the rear end of the upper surface of the workbench, a guide roller is arranged at the upper end of the frame, and a guide shearing assembly is arranged at the front end of the frame, and the guide shearing assembly comprises:

[0009] A shearing groove is provided at the front end of the shearing plate, and a bidirectional blade is fixedly installed at the center of the inner upper end of the shearing groove, and the bidirectional blade can move synchronously with the shearing plate.

[0010] Preferably, the distance between the upper guide plate and the lower guide plate is consistent with the thickness of the shear plate, and the shear plate can pass through the gap between the upper guide plate and the lower guide plate when moving forward.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the present invention provides a technical solution: a firecracker insertion device, comprising a workbench 1, a lead mold plate 2 is arranged at the front end of the upper surface of the workbench 1, a frame 3 is fixedly installed at the rear end of the upper surface of the workbench 1, a guide roller 4 is arranged at the upper end of the frame 3, and a guide shearing assembly is arranged at the front end of the frame 3.

[0026] The guide shearing assembly includes: a mounting groove 501, an electric push rod 506 and a shearing groove 509. The mounting groove 501 is opened on the front side surface of the frame 3. A limiting roller 502 is rotatably installed on the upper end of the mounting groove 501. There are two limiting rollers 502. The two limiting rollers 502 are arranged in a horizontal linear array. The distance between the two limiting rollers 502 is the same as the diameter of the lead wire, which can further guide and limit the lead wire passing through, reduce the deviation of the lead wire when it moves, and the inner center of the mounting groove 501 is fixed. An upper guide plate 503 is installed, and a lower guide plate 504 is fixedly installed at the lower end of the inner part of the installation groove 501. The upper guide plate 503 and the lower guide plate 504 have the same thickness and are located in the same horizontal plane. Guide holes 505 are opened on the upper surfaces of the upper guide plate 503 and the lower guide plate 504. When the lead passes through the limiting roller 502, it will enter the guide hole 505 in the upper guide plate 503, and then enter the guide hole 505 in the lower guide plate 504, and finally fall into the lead mold plate 2 for insertion.

[0027] The electric push rod 506 is fixedly installed on the rear inner wall surface of the installation groove 501, and a fixing plate 507 is fixedly installed at the front end of the electric push rod 506, and a shearing plate 508 is fixedly installed at the front end of the fixing plate 507. When the electric push rod 506 is started, the shearing plate 508 can be driven to move synchronously through the fixing plate 507. The distance between the upper guide plate 503 and the lower guide plate 504 is consistent with the thickness of the shearing plate 508. The shearing groove 509 is opened at the front end of the shearing plate 508, and a bidirectional blade 510 is fixedly installed at the center of the upper end of the shearing groove 509. The bidirectional blade 510 can move synchronously with the shearing plate 508. The width of the bidirectional blade 510 is consistent with the width of the guide hole 505, and the position of the bidirectional blade 510 is adapted to the position of the guide hole 505. When the bidirectional blade 510 moves forward, it can cooperate with the bottom surface of the upper guide plate 503 to cut off the lead wire, so that the lead wire can fall into the lead mold plate 2 to complete the plug-in.

[0028] When the bidirectional blade 510 moves forward to cut the lead, the new lead will move downward and enter the inside of the cutting groove 509, that is, the rear end of the bidirectional blade 510. At this time, the electric push rod 506 drives the bidirectional blade 510 to reset and the new lead can be cut again. There is no need to start the electric push rod 506 to drive the blade to reset before the new lead comes down before the next cutting, which slows down the processing speed and efficiency.

[0029] Limiting grooves 601 are provided on the inner wall surfaces on both sides of the installation groove 501, and a slider 602 is slidably connected inside the limiting groove 601. The outer wall of the slider 602 is fixedly connected to the outer wall of the fixed plate 507. The slider 602 can only perform linear motion in the front-to-back direction inside the limiting groove 601. Through the cooperation of the set limiting groove 601 and the slider 602, the movement of the fixed plate 507 can be guided and limited, so that the fixed plate 507 maintains linear motion in the front-to-back direction, avoiding offset that causes the shear plate 508 to get stuck, affecting the cutting and insertion of the lead.

[0030] The cut lead will fall downward under the action of its own gravity into the lead mold plate 2 to complete the insertion and the lead can then be driven to move downward immediately. After the movement is completed, the electric push rod 506 can be started immediately to drive the two-way blade 510 to move backward and reset, and the lead can be cut again. There is no need to start the electric push rod 506 to drive the blade to reset before the new lead comes down before the next cutting can be performed. The movement of the two-way blade 510 can be guided and limited by the cooperation of the set limit groove 601 and the slider 602 to avoid jamming and affecting the cutting and insertion of the lead.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
