Description

Technical Field

[0001] The utility model relates to a fireproof paper feeding mechanism for a fireworks cylinder row group basin. Background Art

[0002] With the continuous improvement of the safety and quality requirements of fireworks, fireproof paper needs to be arranged on the sides of each cylinder row to avoid the phenomenon of cross-fire between cylinder rows and improve the structural strength of the block formed by combining multiple cylinder rows. In order to complete the assembly of fireproof paper to meet market demand, in the early stage, we designed and developed some fireproof paper assembly mechanisms, such as the "fireproof paper assembly mechanism of a fireworks group basin machine forming system" disclosed in the Chinese utility model patent document with the authorization announcement number of CN 221037115 U; such as the "feeding mechanism of a fireworks group basin machine forming system" disclosed in the Chinese utility model patent document with the authorization announcement number of CN 221037114 U; a "fireproof paper processing device for special-shaped combined fireworks" - application number 2024202575178; a "fireproof paper assembly mechanism of a fireworks group basin machine forming system" - application number 2023227307094; a "fireproof paper assembly mechanism for fireworks group basin forming" - application number 2024200256981.

[0003] In the prior art, the paper tape unrolled from the paper roll is sent into the forming system of the fireworks group basin machine and cut into the fireproof paper between each cylinder row after being cut. Its disadvantage is that the paper tape needs to be cut during the assembly process, which affects the forming efficiency of the group basin. However, if the fireproof paper is cut and then assembled, the prior art lacks a corresponding feeding mechanism that can individually transport single sheets of fireproof paper into the forming mechanism. Summary of the Utility Model

[0004] In order to solve the above disadvantages, the technical problem to be solved by the utility model is to provide a fireproof paper feeding mechanism for a fireworks cylinder row group basin, which can complete the individual transportation of the cut fireproof paper, thereby improving the group basin efficiency. To solve the above technical problem, the technical solution adopted by the utility model is that a fireproof paper feeding mechanism for a fireworks cylinder row group basin is characterized by comprising a feeding conveyor assembly, a lifting assembly, and a pushing assembly:

[0005] The feeding conveyor assembly transports the fireproof paper in the left-right direction to the working position; the feeding conveyor assembly bears the fireproof paper at the working position;

[0006] The lifting assembly is arranged below the feeding conveyor assembly. After the fireproof paper reaches the working position, the lifting assembly pushes the fireproof paper upward in the up-down direction to be separated from the feeding conveyor assembly up and down;

[0007] The pushing component is located on one side of the feeding conveyor component. After the fireproof paper is separated from the feeding conveyor component vertically, the pushing component pushes one side of the fireproof paper in the front-back direction, pushing the fireproof paper away from above the feeding conveyor component.

[0008] The beneficial effects of the present utility model are that it can convey the cut fireproof paper to the forming mechanism of the fireworks cylinder row potting machine one by one, thereby improving the potting efficiency. At the same time, when this feeding mechanism is used for potting special-shaped cylinder rows, it can also effectively avoid waste of the paper tape.

[0009] In one embodiment, the feeding conveyor component is a feeding conveyor belt. The feeding conveyor belt carries the fireproof paper and conveys the fireproof paper in the left-right direction to the working position; a limiting member is provided corresponding to the working position on the feeding conveyor belt.

[0010] The lifting component is arranged below the feeding conveyor belt. After the fireproof paper reaches the limited position of the limiting member, the lifting component pushes the fireproof paper upward in the up-down direction to be separated from the feeding conveyor belt vertically.

[0011] The pushing component is located on one side of the feeding conveyor belt. After the fireproof paper is separated from the feeding conveyor belt vertically, the pushing component pushes one side of the fireproof paper in the front-back direction, pushing the fireproof paper away from above the feeding conveyor belt.

[0012] In one embodiment, the lifting component adopts an air blowing component, including air holes distributed on or below the feeding conveyor belt. The air holes are communicated with an air source, and the gas released by the air holes pushes the fireproof paper upward to be separated from the feeding conveyor belt. The air source is such as an air storage tank or a blower, etc.

[0013] In one embodiment, the feeding conveyor belt is composed of a plurality of spaced-apart conveyor strips; the lifting component includes several lifting members located in the intervals of the conveyor strips. The lifting members are connected to a lifting mechanism, and when the lifting mechanism drives the lifting members to move upward, it pushes the fireproof paper upward to be separated from the feeding conveyor belt.

[0014] In one embodiment, the pushing component includes a base body connected to a pushing driving member. A plurality of pushing forks are provided at the front end of the base body. The pushing forks have downwardly bent portions; the lifting members are provided with channels through which the downwardly bent portions pass.

[0015] In one embodiment, a support plate for abutting against the feeding conveyor belt is provided below the feeding conveyor belt.

[0016] In one embodiment, a guiding slit is provided on one side of the feeding conveyor belt. The guiding slit is located on the opposite side of the pushing component. Further, a fork-passing slit through which the pushing forks pass is provided on the guiding slit.

[0017] In one embodiment, the fireproof paper feeding mechanism further includes a paper picking component, which includes a negative pressure paper sucking member. The paper picking component sucks single fireproof papers one by one and places them onto the feeding conveyor component.

[0018] In one embodiment, a sizing component for applying glue onto the upper surface of the fireproof paper is provided on the feeding conveyor component.

[0019] In one embodiment, the feeding conveyor component includes a telescopic needle and a support body. After the telescopic needle penetrates into the fireproof paper, a needle driving member drives the needle to convey the fireproof paper in the left - right direction to the working position; the support body bears the fireproof paper at the working position. Further, the support body adopts a support plate. The support plate is provided with a plurality of spaced areas corresponding to the working position as the lifting channels for the lifting members; a guiding needle groove for guiding the movement of the telescopic needle is provided on the support plate; a limiter for limiting the height position of the fireproof paper is provided on the support plate. A needle passing groove corresponding to the guiding needle groove is provided on the limiter. The needle passing groove has an open end. The telescopic needle performs telescopic movement within the needle passing groove, and the telescopic needle performs horizontal movement in the left - right direction along the needle passing groove and the guiding needle groove.

[0051] Embodiment 1: Refer to the appendix Figures 1-4 , which reflects a specific structure of the present utility model. The fire - insulating paper feeding mechanism of the fireworks cylinder row basin - assembling includes a feeding conveyor belt, a lifting component, and a pushing component:

[0052] In the example, the feeding conveyor belt is composed of five conveyor strips 101 arranged at intervals; the feeding conveyor belt carries the fire - insulating paper 100 and conveys the fire - insulating paper 100 in the left - right direction; limit members 109 for the fire - insulating paper 100 in the left - right direction are provided on the feeding conveyor belt. In the example, a support plate 102 for supporting the feeding conveyor belt is provided below the feeding conveyor belt. This can prevent the conveyor strips 101 from sagging and causing deviation in the position of the fire - insulating paper 100.

[0053] The lifting component is located below the feeding conveyor belt. After the fire - insulating paper 100 reaches the working position defined by the limit members 109, the lifting component pushes the fire - insulating paper 100 upward in the up - down direction to separate it from the feeding conveyor belt. In the example, the lifting component includes five lifting members 107 located in the interval areas of the conveyor strips 101. The lifting members 107 are connected to the lifting cylinders 108. When the lifting cylinders 108 drive the lifting members 107 to move upward, the fire - insulating paper 100 is pushed upward to separate it from the feeding conveyor belt. Setting the interval areas can avoid the movement interference between the lifting members 107 and the feeding conveyor belt.

[0054] The pushing assembly is located at the rear side of the feeding conveyor belt. After the fire-isolating paper 100 is separated from the feeding conveyor belt, the pushing assembly pushes one side of the fire-isolating paper 100 in the front-to-back direction, pushing the fire-isolating paper 100 away from the top of the feeding conveyor belt. In the example, the pushing assembly includes a base 104 connected to a pushing drive cylinder 103, and eight pushing forks 105 are provided at the front end of the base 104. The pushing forks 105 have a lower bent portion 110; the lifting member 107 is provided with a channel 106 through which the lower bent portion 110 passes.

[0055] During operation, after the feeding conveyor belt composed of the conveying strip 101 transmits the fire-proof paper 100 to the working position, the lifting member 107 receives and pushes the fire-proof paper 100 upward and separates from the feeding conveyor belt; the pushing fork 105 pushes the fire-proof paper 100 away from the top of the feeding conveyor belt and enters the lifting plate 111 of the pot-forming mechanism of the pot-forming machine to complete the feeding work. Then the equipment feeds in a cylinder row 112 to cover the fire-proof paper 100. Glue is applied on the cylinder row 112 and the fire-proof paper 100 so as to be bonded layer by layer. Multiple cylinder rows and fire-proof paper are bonded into a block-shaped whole to complete the pot-forming machine.

[0056] The lower curved portion 110 increases the contact surface between the push fork 105 and the side edge of the paper, ensuring that the side edge of the fire-proof paper 100 will not separate from the push fork 105 during pushing, thereby improving working reliability. The channel 106 ensures that the lower curved portion 110 abutting against the edge of the paper in the middle can pass through the lifting member 107.

[0057] By adopting the above scheme, the cut fire-proof papers can be transported one by one to the forming mechanism of the firework tube assembly machine, and there is no need to cut the paper tape during the assembly process, thereby improving the assembly efficiency.

[0058] The feeding mechanism is applied to a pot assembly machine for a special-shaped cylinder row. The pot assembly machine for a special-shaped cylinder row is disclosed in the Chinese invention patent document with the authorization announcement number CN116929155A, "A special-shaped cylinder row forming device for special-shaped combined fireworks"; the Chinese invention patent document with the authorization announcement number CN116907283A, "A special-shaped cylinder row forming equipment for special-shaped combined fireworks", etc.

[0059] In the special-shaped cylinder row group basin, since the outer peripheral contour shape of the special-shaped cylinder row is different from that of the straight cylinder row, it is not rectangular but approximately trapezoidal or parallelogram-shaped: The cylinder rows with a trapezoidal outer peripheral contour shape include: fan-shaped cylinder rows (such as cylinder row 112 in this example), W-shaped cylinder rows, V-shaped cylinder rows, and five-finger-shaped cylinder rows. The cylinder rows with a parallelogram-shaped outer peripheral contour shape include left-tilted cylinder rows and right-tilted cylinder rows. The shape of the fireproof paper should also correspond to that of the cylinder row. For example, the fireproof paper 100 in this example is a trapezoidal fireproof paper corresponding to cylinder row 112. If the paper tape is cut during assembly to make trapezoidal fireproof paper, since the widths of the upper and lower bases of the trapezoidal fireproof paper are different, it is very difficult to efficiently adjust the trapezoidal fireproof paper in the up and down direction when cutting along the paper tape for feeding. Only the triangular scraps can be cut between two trapezoidal fireproof papers to ensure that the cut trapezoidal fireproof papers have the same direction, thus resulting in waste of the paper tape. When using a single sheet of fireproof paper to form the basin, it can be cut along the side of the trapezoid during pre-cutting, and then all the cut trapezoidal fireproof papers are stacked in the same direction for standby, and then fed into the basin-forming equipment by the feeding mechanism of the present utility model, so that waste of the paper tape can be effectively avoided. The principle of the parallelogram-shaped fireproof paper is the same and will not be elaborated.

[0060] Embodiment 2: Refer to the appendix Figures 5-10 , which reflects another specific structure of the present utility model. The difference from Embodiment 1 is that: in the example, a guiding slit 201 is provided on one side of the feeding conveyor belt 207, and the guiding slit 201 is located on the opposite side of the pushing assembly. This ensures that the direction of the fireproof paper is not disrupted during the pushing process. In the example, a fork-passing slit 203 through which the pushing fork 202 passes is provided on the guiding slit 201. This enables the pushing fork 202 to pass through the guiding slit 201 to push the fireproof paper 210 into place.

[0061] In the example, the guiding slit 201 is located between the positioning plate 204 and the lifting guiding plate 205. The lifting guiding plate 205 prevents the lifting plate of the basin-forming mechanism of the basin-forming machine and the cylinder rows 206 and fireproof papers 210 stacked on the lifting plate from being disordered, especially when the glue has not dried and solidified.

[0062] In the example, the fireproof paper feeding mechanism further includes a paper-taking assembly 208. The paper-taking assembly 208 includes a negative-pressure paper-sucking member 209. After the paper-taking assembly 208 sucks a single sheet of fireproof paper 210, it moves along the guide rail 213 and places the single sheet of fireproof paper 210 one by one on the feeding conveyor belt 207 through the receiving conveyor belt 211 connected to the feeding conveyor belt 207.

[0063] In the example, a glue-applying assembly 214 is provided on the feeding conveyor belt. The glue-applying assembly 214 is composed of several rollers to apply glue to the upper surface of the fireproof paper 210. In other embodiments, glue can also be applied to the lower surface of the fireproof paper 210.

[0064] In the example, the feeding conveyor belt 207 of the fire-separating paper feeding mechanism is located below the slideway 215 of the vertical cylinder row 216 of the special-shaped cylinder row basin machine. The left-right direction limiting members 219 for the fire-separating paper 210 are provided on the feeding conveyor belt 207, and the position adjusting screw 218 is provided on the limiting member 219 to facilitate adjusting the position of the limiting member according to the specification of the fire-separating paper.

[0065] The vertical cylinder row 216 is fed into the forming mechanism, and the lifting plate presses on the fire-separating paper 210 to be processed into a fan-shaped cylinder row 217.

[0066] Example 3: Refer to the appendix Figure 11 , reflecting another specific structure of the present utility model. The difference from Example 2 is that: in Example 2, the lower end 309 of the cylinder row faces the feeding conveyor belt. In this example, the upper end 308 of the cylinder row faces the feeding conveyor belt. Only the length of the pushing fork 310 may need to be adjusted according to the situation to ensure that the pushing fork 310 can pass through the relatively thick second lifting guide plate 311 to push the fire-separating paper 312 in place. The through-fork gap through which the pushing fork 310 passes is also provided on the second lifting guide plate 311.

[0067] Example 4: Refer to the appendix Figures 12-13 , reflecting another specific structure of the present utility model. The difference from Example 1 is that: the lifting component adopts an air-blowing component. The air-blowing component includes air holes 402 distributed below the feeding conveyor belt 401. The air holes 402 are connected to an air source (not shown in the figure), and the gas released from the air holes pushes the fire-separating paper 403 to move upward and separate from the feeding conveyor belt 401. The air source is such as an air storage tank or a blower, etc. The pushing component adopts a pneumatic paper-pushing folding plate 404 that pushes one side of the fire-separating paper 403.

[0068] Example 5: Refer to the appendix Figure 14 , reflecting another specific structure of the present utility model. The difference from Example 4 is that: the air holes 501 of the air-blowing component are distributed on the feeding conveyor belt 502. A positive pressure air box (not shown in the figure) is provided inside the feeding conveyor belt 502. The air holes 501 are connected to the positive pressure air box, and the positive pressure air box is connected to the air source.

[0069] Example 6: Refer to the appendix Figures 15-19 , reflecting another specific structure of the present utility model. The difference from Example 1 is that the feeding conveyor component is different. In this example, the feeding conveyor component includes a telescopic needle 601 and a support body - a support plate 602. After the telescopic needle 601 pierces into the fire-separating paper 603, the needle horizontal driving cylinder 604 drives the telescopic needle 601 to convey the fire-separating paper 603 in the left-right direction to the working position; the support body bears the fire-separating paper 603 at the working position.

[0070] In the example, the material taking component 605 sucks a single piece of fire-proof paper 603, and places the single piece of fire-proof paper 603 one by one on the support plate 602 of the feeding conveyor component through the material receiving conveyor belt 606 connected to the support plate 602. A gluing component 611 for applying glue to the fire-proof paper 603 is provided on the material receiving conveyor belt 606. The fire-proof paper 603 after gluing enters the support plate 602, and the telescopic piercing needle 601 moves to pierce the fire-proof paper 603. The horizontal piercing needle driving cylinder 604 drives the telescopic piercing needle 601 to move in the left and right directions along the guide needle groove 607, and the fire-proof paper 603 is transported to the working position and carried by the support plate 602. Then the telescopic piercing needle 601 retracts and exits the fire-proof paper 603, and resets to the starting position in the left and right directions. The horizontal piercing needle driving cylinder 604 is a cylinder with adjustable stroke. In order to prevent the lifting member 608 from interfering with the movement of the support plate 602 when it rises, the support plate 602 is provided with a plurality of spacing areas 609 corresponding to the working positions as lifting channels for the lifting member 608 .

[0071] In order to ensure that the telescopic puncture needle 601 can be smoothly inserted into the fire-proof paper 603, a stopper 610 is provided on the support plate 602 to limit the height position of the fire-proof paper 603. A puncture needle passing groove 612 is provided on the stopper 610 corresponding to the guide needle groove 607. The puncture needle passing groove 612 has an open end. The telescopic puncture needle 601 telescopically moves in the puncture needle passing groove 612. The telescopic puncture needle 601 moves horizontally in the left and right directions along the puncture needle passing groove 612 and the guide needle groove 607. The installation position of the stopper 610 can be adjusted according to the specifications of the fire-proof paper.

[0072] The work of the lifting component and the pushing component is the same as that in the above embodiment and will not be described in detail.

[0073] Example 7: See attached Figure 20 , reflecting another specific structure of the utility model. The difference from Example 1 is that the feeding mechanism of this example is applied to the vertical tube row basin assembly machine. The outer peripheral contour shape of the vertical tube row 701 is a rectangle, and the fire-proof paper 702 is also a corresponding rectangle.

[0074] The workflow of the example is briefly described as follows: the pre-cut rectangular fire-proof paper 702 is stacked for standby use, the material taking component 703 absorbs a single fire-proof paper 702, and the single fire-proof paper 702 is placed one by one on the feeding conveyor belt 705 through the receiving conveyor belt 704 to complete the gluing. After the feeding conveyor belt 705 transports the single fire-proof paper 702 to the working position defined by the limiter 706, the lifting component 707 receives and pushes the fire-proof paper 702 upward to separate from the feeding conveyor belt; the pushing component 708 pushes the fire-proof paper 702 away from the top of the feeding conveyor belt and onto the lifting plate 709 of the basin assembly machine forming mechanism, completing the feeding of the fire-proof paper. The lifting plate 709 is reset after being lowered step by step by the screw nut assembly 710 driven by the motor. The specific structural principle is the same as that of Example 1 and will not be repeated.

[0075] In other embodiments, the feeding and conveying assembly composed of the air blowing assembly, the telescopic needle inserting part, and the support body can also be used for the feeding mechanism of the upright cylindrical row group basins.

[0076] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. This specification selects and describes these embodiments in combination with the drawings to better explain the principle and practical application of the present invention, so that those skilled in the art can well understand and utilize the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
