Description

Technical Field

[0001] The utility model relates to the technical field of whip-tying machines, in particular to a single-layer whip-tying machine with adjustable density. Background Art

[0002] With the continuous development of the fireworks and firecrackers industry, the market has put forward higher requirements on the diversity and quality of firecracker products. Among them, the density of firecrackers, as one of the important indicators to measure the quality of firecracker products, directly affects the burning effect, safety and user experience of firecrackers; the traditional adjustment method is to directly increase the running speed of the conveyor belt by the motor, but when the rotation speed of the motor is too fast, it may cause the firecrackers to be arranged unevenly on the conveyor belt or transmission mechanism, and even overlap or misalignment, which will not only affect the appearance quality of the firecrackers, but also may cause leakage, breakage and other problems during packaging, thereby affecting the firing effect and safety of the firecrackers. In view of this, a single-layer firecracker knotting machine with adjustable density is proposed. Utility Model Content

[0003] In order to solve at least one of the above technical shortcomings, the utility model provides a single-layer firecracker making machine with adjustable density, including a hopper, a discharge plate is arranged under the hopper, and a slide bar for intermittently conveying the falling firecrackers is arranged on the side wall of the discharge plate.

[0004] Furthermore, a through rectangular groove is provided on one side of the blanking plate, a through hole is provided in the middle of the groove, the slide rod is plugged into the through hole, and an extension rod arranged in a transverse circular array is provided in the middle of the slide rod.

[0005] Furthermore, the sum of the lengths of the extension rods symmetrically arranged in pairs is equal to the width of the groove, and the sum of the lengths of the extension rods symmetrically arranged in pairs is the same as the length from the through hole to the inner wall of the blanking plate on the other side, and a matching limiting wheel is also provided on one side of the extension rod.

[0006] Furthermore, the limiting wheel is provided with limiting teeth arranged in a circular array, and a matching limiting plate is also provided under the limiting wheel. The limiting plate rotates on the blanking plate through an axis rod, and a side connecting plate is also provided on the plate wall on one side of the blanking plate. A spring is provided at the bottom of the side connecting plate, and the output end of the spring is connected to the top of the limiting plate.

[0007] Furthermore, a vertically mounted convex strip is provided at one end of the limiting plate, and the limiting plate realizes unidirectional rotation through the convex strip and the limiting tooth groove, and a sliding strip with a right-angled triangle at the top is also provided on the limiting plate.

[0008] Furthermore, the convex strip has the same shape as the limiting tooth groove, and a matching turning strip is provided above the sliding strip, on which turning blades are arranged in a circular array, and the output end of the turning blade is a right-angled triangle, and a micro motor is also provided in the middle of the turning strip, and the micro motor is installed on the wall of the blanking plate through a mounting plate.

[0009] Beneficial effects: The hopper replaces the original discharging hopper on the single-layer braiding machine. When it is necessary to adjust the density of firecrackers, the PCB board is connected to the micro motor, and the rotation speed of the micro motor is adjusted in cooperation with the supporting controller. When it is necessary to adjust the spacing of firecrackers, the speed of the micro motor is slowed down, and the pressing speed of the rotating blades on the rotating bar against the sliding bar becomes slower, so that the limiting speed of the limiting piece against the limiting tooth grooves of the limiting wheels on the sliding bar becomes slower, so that the extension rods arranged in a horizontal circumferential array on the sliding bar achieve segmented intermittent feeding of the falling firecrackers.

Detailed Embodiments

[0016] Please refer to Figures 1 to 4 ;

[0017] This embodiment provides a single-layer firecracker braiding machine with adjustable density, including a hopper 1, a blanking plate 101 is arranged below the hopper 1, and a sliding bar 2 for intermittently conveying the falling firecrackers is arranged on the side wall of the blanking plate 101; Refer to Figures 1 to 4, a rectangular groove 102 is provided on one side of the blanking plate 101, and a through hole is provided in the middle of the groove 102. The sliding rod 2 is inserted into the through hole. An extension rod 203 is arranged in a horizontal circular array in the middle of the sliding rod 2. The sum of the lengths of the two symmetrically arranged extension rods 203 is equal to the width of the groove 102, and the sum of the lengths of the two symmetrically arranged extension rods 203 is the same as the length from the through hole to the inner wall of the other blanking plate 101. A matching limiting wheel 201 is also provided on one side of the extension rod 203. A circumferentially arranged limiting tooth groove 202 is provided on the limiting wheel 201. A matching limiting piece 3 is also provided below the limiting wheel 201. The limiting piece 3 rotates on the blanking plate 101 through a shaft rod. A side connecting plate 104 is also provided on the side wall of one side of the blanking plate 101. A spring 105 is provided at the bottom of the side connecting plate 104. The output end of the spring 105 is connected to the upper part of the limiting piece 3. A vertically installed convex strip 301 is provided at one end of the limiting piece 3. The limiting piece 3 realizes one-way rotation through the convex strip 301 and the limiting tooth groove 202. A sliding strip 302 with a right-angled triangle at the top is also provided on the limiting piece 3. The convex strip 301 has the same shape as the limiting tooth groove 202. A matching rotating strip 4 is also provided above the sliding strip 302. A circumferentially arranged rotating blade is provided on the rotating strip 4. The output end of the rotating blade is in the shape of a right-angled triangle. A micro motor 5 is also provided in the middle of the rotating strip 4. The micro motor 5 is installed on the wall of the blanking plate 101 through a mounting plate;

[0018] In a specific embodiment, the micro motor 5 is equipped with a matching PCB board, and the PCB board is equipped with a controller to control the rotation speed of the micro motor 5. The micro motor 5 is arranged on the side wall of the blanking plate 101 through a mounting plate. One end of the limiting piece 3 is connected to a connecting rod 103 on the blanking plate 101 to make the limiting piece 3 movable. When two groups of firecrackers are placed in the hopper 1 and the firecrackers fall into the blanking plate 2, they first fall between the two extension rods 203 above the sliding rod 2. When the rotating strip 4 drives the sliding strip 302 downward through the micro motor 5, at this time, the limiting piece 3 is driven to rotate downward by the connecting rod 103, so that the sliding rod 2 rotates clockwise by a certain angle due to the gravity of the falling firecrackers, and at this time, the convex strip 201 of the sliding rod 2 is tangent to the outer wall of the limiting wheel 201, which does not affect the rotation of the limiting wheel 301. At the same time, the spring 105 drives the limiting piece 3 to reset until the next limiting tooth groove 202 is stuck with the convex strip 301, completing the blanking of one firecracker. Work in this way repeatedly. By adjusting the controller supporting the micro motor 5, the rotation speed of the micro motor 5 for the rotating blade 4 is adjusted to adjust the density of the firecrackers, solving the problem that the arrangement of the falling firecrackers is not neat enough and there are overlapping or misalignment situations caused by directly controlling the speed of the motor on the conveyor belt.

[0019] Further, the hopper is replaced with the blanking hopper of a single-layer firecracker tying machine, and the single-layer firecracker tying machine is a commonly used device in the technical field, and its specific structure will not be elaborated here.
