Description

Technical Field

[0001] This invention relates to the field of fireworks technology, and in particular to a method for spiral printing a fireworks base. Background Technology

[0002] Currently, firework bases are typically made of corrugated cardboard. To ensure the base's strength, multiple layers of glue are usually applied, and sometimes even cement is attached. However, this method results in a very high material content in the firework base, and it is usually difficult to recycle and reuse after a single use, leading to waste. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a method for spiral printing firework bases, which achieves the effect of efficiently producing recyclable firework bases by printing firework tubes one by one.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention provides a method for spiral printing a fireworks base, applied to a 3D printing device, comprising the following steps:

[0006] A. A molding base, wherein the base has at least one cylindrical portion;

[0007] B. Print a ring-shaped structure in the cylinder;

[0008] C. Repeat step B several times, with each ring structure located directly above the previous ring structure, and the end of each ring structure being the beginning of the previous ring structure; multiple ring structures are stacked in sequence to form a firework tube.

[0009] Furthermore, in step A, there are multiple cylinder positions, with adjacent positions spaced apart.

[0010] Furthermore, this also includes:

[0011] D. Keep the print head in printing mode or switch it to off mode, and control the print head to move from the current cartridge position to the next cartridge position, and execute steps B and C at the next cartridge position;

[0012] E. Repeat step D until all tubes are printed with fireworks tubes.

[0013] Furthermore, in step C, whenever a ring structure is formed, the control base is lowered relative to the print head, and the height of the descent is equal to the height of a ring structure.

[0014] In step D, when the printhead moves from the current cartridge position to the next cartridge position, the control base rises so that the height between the base and the printhead returns to the initial state.

[0015] Furthermore, step A specifically includes:

[0016] A1. Print out a cylindrical shape;

[0017] A2. A partition is formed on one side of the cylinder, and the thickness of the partition is greater than the thickness of the cylinder.

[0018] A3. Repeat steps A1 and A2 until all cylinders are formed;

[0019] A4. Print reinforcing ribs on the outermost outer part of the cylinder;

[0020] Each cylinder position is connected to at least two partitions, and each partition is connected to at least two cylinder positions.

[0021] Furthermore, the bottom of the cylinder is provided with at least two through holes;

[0022] Prior to step A1, the method further includes: providing a continuous strip structure for being recognized by a 3D printing device to form a base;

[0023] After step C, the strip structure is separated from the base.

[0024] Furthermore, in step D, the printhead is switched to the off state, specifically including:

[0025] D1. Detect whether the current number of times the ring structure is printed is the last time for this cylinder. If so, proceed to step D2; otherwise, continue to step C.

[0026] D2. Control the heating module of the print head to stop working, so that the adhesive in the print head gradually cools down and solidifies as the last ring structure is printed, until it is basically solidified and no longer flows out when the printing is completed;

[0027] D3. Control the printhead's switching valve to the closed state, and simultaneously control the heating module to restart.

[0028] Furthermore, in step D, the printhead remains open, specifically including:

[0029] D4. Detect whether the current number of times the ring structure is printed is the last time for this cylinder. If so, proceed to step D5; otherwise, continue to step C.

[0030] D5. With the printhead still open, control the printhead to move relative to the base so that the printhead moves to the next cartridge position. During the movement, the adhesive falls into the gap between the two cartridge positions.

[0031] D6. The print head performs step B at the next cartridge position, and after performing step B multiple times, moves back and forth between the two cartridge positions to form a reinforcing section between the two cartridge positions;

[0032] In step D6, the specific values ​​of several times are less than the specific values ​​of several times in step C.

[0033] Furthermore, the back-and-forth movement between the two cylinder positions after performing step B multiple times specifically includes:

[0034] D61. After completing the printing of a ring structure, the print head moves towards the previous cylinder position, and the moving distance is L1;

[0035] D62. The print head returns to its original position and completes the printing of the next annular structure. Then it moves towards the previous cylinder position, with a moving distance of L2. Where L2 = k * L1, k is a constant and the value of k ranges from 1.1 to 1.3.

[0036] D63. Repeat D62 until L n The value represents the distance between two adjacent cylinder positions;

[0037] D64. Maintain a movement distance of L. n Execute D62 until the length of the reinforced section is L. n The thickness of the part reaches the preset value.

[0038] The beneficial effects of this invention: This invention achieves the effect of spiral printing of fireworks tubes by utilizing the cooperation of various modules of a 3D printing equipment through 3D printing, effectively reducing costs. Attached Figure Description

[0039] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0040] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, the present invention provides a method for spiral printing a fireworks base, applied to a 3D printing device, comprising the following steps:

[0042] A. A molding base, wherein the base has at least one cylindrical portion;

[0043] B. Print a ring-shaped structure in the cylinder;

[0044] C. Repeat step B several times, with each ring structure located directly above the previous ring structure, and the end of each ring structure being the beginning of the previous ring structure; multiple ring structures are stacked in sequence to form a firework tube.

[0045] The 3D printing device that implements the present invention must have at least three drive modules: an X-axis module, a Y-axis module, and a Z-axis module. The three drive modules work together to control the movement of the print head relative to the print head in three-dimensional space in order to print an object of the desired shape.

[0046] Based on this, the present invention uses the X-axis module and Y-axis module in cooperation to control the movement of the print head relative to the print base, thereby achieving the effect of printing a ring structure on the print base; after printing a ring structure, the Z-axis module drives the print head to rise a height relative to the print base, the height of which is determined by the thickness of the ring structure, so that the print head prints the next ring structure with the end of the ring structure as the beginning... In the above way, the printing of multiple sequentially stacked ring structures is realized, and the cylinder is formed by the cooperation of multiple ring structures.

[0047] Because the printing path of the print head is spiral, this invention can achieve continuous printing of a cylinder, which is beneficial to improving efficiency. In addition, the firework base made by this invention is made of plastic, which is easier to recycle and reuse, thus benefiting the environment.

[0048] Specifically, in step A, the number of cylinder positions can be a single one or multiple. When there are multiple cylinder positions, adjacent positions are spaced apart.

[0049] In this embodiment, taking the number of cylinder positions as an example, the present invention further includes:

[0050] D. Keep the print head in printing mode or switch it to off mode, and control the print head to move from the current cartridge position to the next cartridge position, and execute steps B and C at the next cartridge position;

[0051] E. Repeat step D until all tubes are printed with fireworks tubes.

[0052] After printing one cylinder, the print head can be closed to stop dispensing material and then moved to the next cylinder position before being reopened for operation. Alternatively, the print head can be kept printing while moving to the next cylinder position, creating a connection between adjacent cylinder positions. Although this increases material usage, it ensures the stability of the cylinder's strength.

[0053] Specifically, in step C, whenever a ring structure is formed, the control base is lowered relative to the print head, and the height of the descent is the height of one ring structure.

[0054] In step D, when the printhead moves from the current cartridge position to the next cartridge position, the control base rises so that the height between the base and the printhead returns to the initial state.

[0055] In this embodiment, step A specifically includes:

[0056] A1. Print out a cylindrical shape;

[0057] A2. A partition is formed on one side of the cylinder, and the thickness of the partition is greater than the thickness of the cylinder.

[0058] A3. Repeat steps A1 and A2 until all cylinders are formed;

[0059] A4. Print reinforcing ribs on the outermost outer part of the cylinder;

[0060] Each cylinder position is connected to at least two partitions, and each partition is connected to at least two cylinder positions.

[0061] In actual use, the printing of the base can be separated from that of the cylinder. That is, after the base is printed, the cylinder is printed from each cylinder position. This method allows the base and the cylinder to be formed separately, so that a device that prints one cylinder position can work with a device that prints multiple cylinders, adapting to the printing cycle and improving efficiency.

[0062] Specifically, the bottom of the cylinder is provided with at least two through holes;

[0063] Prior to step A1, the method further includes: providing a continuous strip structure for being recognized by a 3D printing device to form a base;

[0064] After step C, the strip structure is separated from the base.

[0065] The strip structure can be meandering, with at least two protrusions at each corresponding position of the cylinder, so that the 3D printing equipment can identify the protrusions and form the cylinder with the center of the line connecting the two protrusions as the center. The thickness of the cylinder is greater than the height of the strip structure. After the base is formed, the strip structure is separated from the base so that the strip structure can be reused.

[0066] By setting the strip structure, the size of each cylinder and the distance between adjacent cylinders in the base formed by this invention meet the requirements, achieving the effect of automated forming and ensuring forming quality and efficiency.

[0067] Specifically, in step D, when the printhead is switched to the off state, the following is included:

[0068] D1. Detect whether the current number of times the ring structure is printed is the last time for this cylinder. If so, proceed to step D2; otherwise, continue to step C.

[0069] D2. Control the heating module of the print head to stop working, so that the adhesive in the print head gradually cools down and solidifies as the last ring structure is printed, until it is basically solidified and no longer flows out when the printing is completed;

[0070] D3. Control the printhead's switching valve to the closed state, and simultaneously control the heating module to restart.

[0071] Specifically, during the printing of the last annular structure of the cylinder, the heating module is gradually cooled down until it stops working, allowing the adhesive to gradually solidify. Ideally, the adhesive should solidify after printing the last annular structure, preventing it from flowing out of the print head. This improves the quality of the formed cylinder and avoids uneven adhesive output, resulting in noticeable bumps or accumulations, caused by the print head closing abruptly. After printing the annular structure, the print head is closed. At this point, the heating module can be reopened, allowing the adhesive to be reheated to the required temperature during print head movement. This ensures that when the print head reopens, the adhesive can flow smoothly and be output for the next cylinder printing.

[0072] This invention is preferably applied to 3D printing equipment using granular adhesive. While linear printing equipment is less expensive, it is prone to uneven adhesive output and particle-like texture / accumulation each time the print head is opened and closed. This invention minimizes this unevenness, ensuring a smooth appearance for each cylinder and preventing scratches caused by particle-like texture / adhesive accumulation.

[0073] The changes in the working state of the heating module in this embodiment can be obtained by those skilled in the art through multiple experiments. The changes are related to parameters such as room temperature, and will not be described in detail here.

[0074] Specifically, as another embodiment of the present invention, in step D, when the print head remains in the open state, the following is specifically included:

[0075] D4. Detect whether the current number of times the ring structure is printed is the last time for this cylinder. If so, proceed to step D5; otherwise, continue to step C.

[0076] D5. With the printhead still open, control the printhead to move relative to the base so that the printhead moves to the next cartridge position. During the movement, the adhesive falls into the gap between the two cartridge positions.

[0077] D6. The print head performs step B at the next cartridge position, and after performing step B multiple times, moves back and forth between the two cartridge positions to form a reinforcing section between the two cartridge positions;

[0078] In step D6, the specific values ​​of several times are less than the specific values ​​of several times in step C.

[0079] In this method, all cylinders are molded as a single piece. Therefore, there are paths formed by the adhesive material between adjacent cylinders. These paths can cover the reinforcing sections, further increasing the thickness of the partitions and allowing the partitions to form reinforcing sections. After the cylinders are printed to a certain height, reinforcing sections can be formed again. The cooperation of two reinforcing sections allows adjacent cylinders to be connected, strengthening their structure and ensuring the cylinders remain reliably upright.

[0080] In this embodiment, the reinforcing part formed in step D6 is preferably located on the side of the opening at the top of the cylinder. That is, the reinforcing part is specially formed when the last few annular structures are formed, so as to minimize the impact of the forming of the reinforcing part on the forming of the cylinder.

[0081] Specifically, the back-and-forth movement between the two cylinder positions after performing step B multiple times includes:

[0082] D61. After completing the printing of a ring structure, the print head moves towards the previous cylinder position, and the moving distance is L1;

[0083] D62. The print head returns to its original position and completes the printing of the next annular structure. Then it moves towards the previous cylinder position, with a moving distance of L2. Where L2 = k * L1, k is a constant and the value of k ranges from 1.1 to 1.3.

[0084] D63. Repeat D62 until L n The value represents the distance between two adjacent cylinder positions;

[0085] D64. Maintain a movement distance of L. n Execute D62 until the length of the reinforced section is L. n The thickness of the part reaches the preset value.

[0086] The final forming of the reinforcing part is a trapezoidal structure similar to an inverted one. Through the setting of steps D61-D64, the length of the moving distance gradually increases until the two cylinders are connected. In addition to supporting the upper adhesive material after the lower adhesive material solidifies to avoid adhesive leakage, this setting can also prevent the print head from colliding with the formed cylinder and causing the cylinder to break (because the output end of the print head is funnel-shaped).

[0087] This method effectively shapes the suspended adhesive material and ensures that even if the adhesive solidifies slowly, the solidified material below can support the material above, preventing leakage. Furthermore, the forming of the reinforcing section can be controlled by the print head through the coordinated movement of the X-axis and Y-axis modules to increase its width, ensuring a larger width and thickness for enhanced strength.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present invention without departing from the scope of the present invention are within the scope of the present invention.
