Abstract
Description
Technical Field
[0001] This invention belongs to the field of daily necessities manufacturing technology, and specifically relates to a method for manufacturing a tubular moxibustion device. Background Technology
[0002] The current process for manufacturing cylindrical moxibustion devices in this field is the production process described in Chinese invention patent CN111904850B. However, in recent years of production, the following shortcomings have been found that require improvement:
[0003] 1. While using an automatic feeding device to feed, compact, and then fill the moxa wool increases its density, it cannot guarantee that the weight of each portion of moxa wool filled into the cylinder will meet the requirements. This is because the filling tube can only fill by volume, not by weight. Therefore, the error described in this solution as "equivalent to completing the moxa wool weight measurement" is uncontrollable. Since the moxa wool content in small moxibustion cylinders is already low, the uncontrollable weight error of each portion of moxa wool will directly lead to substandard product quality. Furthermore, the moxa wool pushed from the filling tube into the feeding cylinder is difficult to recycle and reuse. These factors combined resulted in a defect rate of nearly 20% due to insufficient moxa wool weight after production using this automatic feeding device, which seriously affected product production. Therefore, weighing became an unavoidable step in the manufacturing process, and it had to be changed back to a process of manually grabbing the moxa wool, accurately weighing it, and then putting it into the feeding cylinder. However, moxa wool is similar to cotton, and the weight grabbed depends entirely on the worker's feel and adjustment after weighing. This step cannot be automated or semi-automated, resulting in a large amount of manpower required and situations where other workers on the production line often wait for the feeding cylinder.
[0004] 2. In this process, the core of the lower mold is stepped with a smaller diameter at the top and a larger diameter at the bottom. The connection between the large diameter section and the small diameter section has a groove facing downwards. The moxibustion tool body is inserted into the groove. The height of the moxibustion tool body is greater than the height of the large diameter section of the bottom mold. Since it only contains the upper mold and the lower mold, and the height of the moxibustion tool body is higher than the large diameter section, the moxibustion tool body and the moxibustion wool must be completely confined within the upper mold and the lower mold when pressing the moxa wool. The upper mold needs to provide both the function of confining the position of the moxa wool and providing the pressure to press the moxa wool. Therefore, the core of the upper mold will inevitably be in direct contact with the moxibustion tool body. If the upper and lower molds are slightly misaligned, the moxibustion tool body will be damaged. Summary of the Invention
[0005] To address the problems existing in the prior art, this invention improves the manufacturing method as follows: First, the weighing process is semi-automated. Individual moxa wool blocks cannot enter the feeding cylinder until they reach the preset standard weight, solving the problem of high defect rates caused by insufficient moxa wool weight in the original automatic feeding device. This also saves significant manpower and improves work efficiency compared to purely manual moxa wool collection. Second, the lower mold has been redesigned, consisting of a middle mold and a bottom mold, ensuring that the moxibustion tool cylinder does not directly contact the upper mold during the pressing process. Simultaneously, the cylinder structure of the upper and middle molds has been improved, allowing for rapid separation between the upper and middle molds after the moxa wool pressing is completed.
[0006] The specific technical solution adopted is as follows: a method for manufacturing a cylindrical moxibustion device, which includes at least the process of making a cylindrical moxibustion device body, and further includes the following steps:
[0007] Step 1. Pre-treatment of moxa wool: After crushing the mugwort into moxa wool, stir it evenly and compress it for the first time. Transfer the compressed moxa wool to the extrusion device. The outlet of the extrusion device is shaped to match the cross-section of the moxibustion device. Then cut the moxa wool extruded from the outlet of the extrusion device into individual moxa wool blocks of uniform length, weigh them, and put the individual moxa wool blocks that meet the preset standard weight range into the feeding cylinder of the feeding mold. Collect the individual moxa wool blocks that do not meet the preset standard weight range and repeat Step 1.
[0008] Step 2. Prepare a special mold set: The special mold set consists of an independent upper mold, a middle mold, and a bottom mold. The middle mold and the bottom mold are assembled together to form a lower mold that cooperates with the upper mold. The upper mold is fixed to the press and is used to provide pressure for pressing the moxa wool. The middle mold and the bottom mold are used for the installation of the independent moxa wool blocks and the moxibustion device body.
[0009] The upper mold plate surface includes at least a plurality of downward-facing upper mold cores and springs located between the upper mold cores;
[0010] The plate surface of the mold has multiple middle cylinder mounting holes. Each middle cylinder mounting hole has a downward-facing middle cylinder. The upper end of the middle cylinder above the middle cylinder mounting hole has an annular segment with a diameter larger than the diameter of the middle cylinder mounting hole. The outer wall of the middle cylinder below the middle cylinder mounting hole has a retaining spring with a diameter larger than the diameter of the middle cylinder mounting hole. The annular segment and the retaining spring together restrict the relative position of the middle cylinder and the middle cylinder mounting hole.
[0011] The bottom mold has multiple upward-facing stepped bottom molds. Each bottom mold consists of a large-diameter section and a small-diameter section located within the large-diameter section. The diameter of the large-diameter section is the same as the diameter of the middle cylinder, and the height of the large-diameter section is less than the height of the small-diameter section. A groove is provided at the connection between the large-diameter section and the small-diameter section. A positioning protrusion is provided at the center of the top of the small-diameter section. The size of the groove matches the size of the moxibustion device cylinder.
[0012] The lower surface of the middle mold has four corners with pillars, and the upper surface of the bottom mold has four corners with positioning grooves. The number and position of the pillars and the positioning grooves are matched.
[0013] Step 3. Install the moxibustion device body and the pad: Insert the moxibustion device body into the groove of the bottom mold, put the pad with the center hole on the positioning protrusion of the bottom mold, and press the pad down until it contacts the top surface of the bottom mold.
[0014] Step 4. Install individual moxa wool blocks: The middle mold is installed above the bottom mold to form the lower mold. The lower surface of the feeding mold is attached to the upper surface of the middle mold and the feeding cylinder is aligned with the middle cylinder. Then, the individual moxa wool blocks in the feeding cylinder of the feeding mold are pressed into the middle cylinder of the middle mold. Then, the feeding mold is moved away.
[0015] Step 5. Pressing the moxa wool: After assembling the middle mold and the bottom mold, the lower mold, which together form the lower mold, is moved below the upper mold. The upper mold core of the upper mold is pressed into the middle cylinder, and then heated and pressurized.
[0016] Step 6. Separate the upper mold from the middle mold to remove the lower mold as a whole. Then separate the middle mold from the bottom mold and remove the cylinder containing the moxa wool. The middle mold and the bottom mold are recycled and reused.
[0017] Step 7. Install the base of the tubular moxibustion device onto the bottom of the cylinder containing moxa wool to obtain the tubular moxibustion device.
[0018] Moreover, the arrangement, quantity, and position of the feed cylinder, upper mold core, middle cylinder, and bottom mold are all consistent.
[0019] Moreover, the annular section of the middle cylinder is an integral structure with the middle cylinder, while the retaining spring is an independent structure. The outer wall of the middle cylinder located below the middle cylinder mounting hole has a groove, and the retaining spring is embedded in the groove. When making the middle mold, the middle cylinder is first placed face down into the middle cylinder mounting hole, and then the retaining spring is embedded in the groove. The annular section and the retaining spring cooperate to prevent the middle cylinder from moving up and down relative to the middle cylinder mounting hole.
[0020] Moreover, the height of the moxibustion tool cylinder is greater than the height of the large-diameter section of the bottom mold, and the height of the small-diameter section is less than the sum of the heights of the large-diameter section and the middle cylinder.
[0021] Furthermore, the spring below the upper mold is used to assist in separating the upper mold from the lower mold in step 6.
[0022] Furthermore, the tube containing pressed moxa wool obtained in step 6 can be further coated with adhesive at the bottom of the base, fitted with a lid on the top, packaged, and sealed.
[0023] Compared with existing technologies, the beneficial effects of this technical solution are as follows:
[0024] 1. The initially compressed moxa wool is transferred to the extrusion device. The outlet of the extrusion device is shaped to match the cross-section of the moxibustion device cylinder. The moxa wool extruded from the outlet of the extrusion device is then cut into individual moxa wool blocks of uniform length, weighed, and the individual moxa wool blocks that meet the preset standard weight range are placed into the feeding cylinder of the feeding mold. This achieves semi-automation of the weighing process. Individual moxa wool blocks cannot enter the feeding cylinder before meeting the preset standard weight, which solves the problem of high defect rate caused by insufficient moxa wool weight in the original automatic feeding device. At the same time, it saves a lot of manpower and improves work efficiency compared to purely manual moxa wool collection.
[0025] II. The lower mold consists of a middle mold and a bottom mold. The diameter of the large-diameter section of the bottom mold is the same as the diameter of the middle cylinder of the middle mold, and the height of the small-diameter section is less than the sum of the heights of the large-diameter section and the middle cylinder. The moxa wool to be pressed is limited by the middle cylinder of the middle mold and the bottom mold. The upper mold core is only used to provide pressure for pressing the moxa wool, thus ensuring that the moxibustion device body does not directly contact the upper mold during the pressing process. Even if the upper and lower molds are not aligned, the middle mold will be subjected to the force of the upper mold core first, giving the operator an opportunity to readjust the position and increasing the fault tolerance. This solves the problem in existing technologies where the upper mold restricts the position of the moxa wool, causing the upper mold core to directly damage the moxibustion device body if it is slightly misaligned.
[0026] Third, without the limiting structure of the ring section and the retaining spring, when the pressing of moxa wool is finished, some of the middle cylinder will inevitably be attached to the upper mold core, the middle cylinder will detach from the middle cylinder mounting hole, and it will not be able to be moved away with the middle mold. The operator has to reach under the press to pull off the middle cylinder attached to the upper mold core, and then put the middle cylinder back into the middle cylinder mounting hole with the middle cylinder facing down. The operation is cumbersome and has safety hazards.
[0027] Therefore, a limiting structure was designed for the middle cylinder of the mold. The annular section and the retaining spring work together to prevent the middle cylinder from moving up and down relative to the middle cylinder mounting hole, thus avoiding the problem that the middle cylinder is still attached to the upper mold core after the moxa wool is pressed and cannot be moved away with the middle mold.
[0028] Fourth, a spring was added between the upper mold core and the upper mold to assist in separating the upper mold from the lower mold. Attached Figure Description

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. The scope of the present invention is not limited to the following embodiments. Furthermore, the present invention is a further optimization and improvement upon CN111904850B; therefore, the unmodified processes for pressing moxa wool, setting the base, lid, and packaging are the same.
[0039] A method for manufacturing a cylindrical moxibustion device includes at least the following steps: making a cylindrical body of the moxibustion device.
[0040] Step 1. Pre-treatment of moxa wool: After crushing the mugwort into moxa wool, stir it evenly and compress it for the first time. Transfer the compressed moxa wool to the extrusion device. The outlet of the extrusion device is shaped to match the cross-section of the moxibustion device. Then cut the moxa wool extruded from the outlet of the extrusion device into individual moxa wool blocks of uniform length, weigh them, and put the individual moxa wool blocks that meet the preset standard weight range into the feeding cylinder of the feeding mold. Collect the individual moxa wool blocks that do not meet the preset standard weight range and repeat Step 1.
[0041] The mixing, initial compression, extrusion, and cutting can all be automated using equipment such as mixers, pressing machines, and cutting machines. After the moxa wool blocks are separated, the weight must be observed manually. Then, according to the preset standard weight range, the independent moxa wool blocks that meet the requirements are placed into the feeding cylinder of the feeding mold, and the independent moxa wool blocks that do not meet the requirements are collected and reprocessed.
[0042] While step 1 cannot be fully automated, it completely solves the problem of defective products caused by insufficient weight of moxa wool due to the automatic feeding device, and also addresses the difficulty in recycling and reusing even substandard moxa wool pushed into the feeding cylinder from the flushing pipe. Furthermore, the semi-automated step 1 still saves significant manpower and improves work efficiency compared to purely manual moxa wool extraction, and eliminates the problem of other workers waiting for the feeding cylinder during purely manual operation. It represents the optimal compromise.
[0043] Step 2. Prepare a special mold set: The special mold set consists of an independent upper mold, a middle mold, and a bottom mold. The middle mold and the bottom mold are assembled together to form a lower mold that cooperates with the upper mold. The upper mold is fixed to the press and is used to provide pressure for pressing the moxa wool. The middle mold and the bottom mold are used for the installation of the independent moxa wool blocks and the moxibustion device body.
[0044] like Figure 1 As shown, the press 1 is equipped with an upper mold, and the upper mold plate 2 has multiple downward-facing upper mold cores 3 and springs 4 located between the upper mold cores; it is also equipped with a bottom mold fixing device 5 and a worktable 6, which helps to determine the position to which the lower mold needs to be moved when pressing moxa wool in step 5.
[0045] like Figure 2 and Figure 3 As shown, the plate surface 9 of the middle mold has multiple middle cylinder mounting holes 12, and each middle cylinder mounting hole is used to install a downward-facing middle cylinder 10. The upper end of the middle cylinder above the middle cylinder mounting hole has an annular segment 7 with a diameter larger than the diameter of the middle cylinder mounting hole. The outer wall of the middle cylinder below the middle cylinder mounting hole is provided with a retaining spring 8 with a diameter larger than the diameter of the middle cylinder mounting hole. The annular segment and the retaining spring cooperate to prevent the middle cylinder from moving up and down relative to the middle cylinder mounting hole. The four corners of the lower surface of the middle mold are provided with columns 11 for installation in conjunction with the positioning groove of the bottom mold.
[0046] Moreover, the annular section of the middle cylinder is an integral structure with the middle cylinder, while the retaining spring is an independent structure. The outer wall of the middle cylinder located below the middle cylinder mounting hole has a groove, and the retaining spring is embedded in the groove. When making the middle mold, the middle cylinder is first placed face down into the middle cylinder mounting hole, and then the retaining spring is embedded in the groove.
[0047] like Figure 4 and Figure 5 As shown, the bottom mold plate 13 has multiple upward-facing stepped bottom molds. Each bottom mold consists of a large-diameter section 14 and a small-diameter section 15 located within the large-diameter section. The diameter of the large-diameter section is the same as the diameter of the middle cylinder, and the height of the large-diameter section is less than the height of the small-diameter section. A groove 16 is provided at the connection between the large-diameter section and the small-diameter section, and a positioning protrusion 17 is provided at the center of the top of the small-diameter section. The size of the groove matches the size of the moxibustion device body. Positioning grooves 18 are provided at the four corners of the upper surface of the bottom mold for installation in conjunction with the columns of the middle mold.
[0048] Step 3. Install the moxibustion device body and the pad: Insert the moxibustion device body into the groove of the bottom mold, put the pad with the center hole on the positioning protrusion of the bottom mold, and press the pad down until it contacts the top surface of the bottom mold.
[0049] Step 4. Install individual moxa wool blocks: The middle mold is installed above the bottom mold to form the lower mold, as shown below. Figure 6 As shown (the moxibustion tool body is sandwiched between the middle cylinder of the middle mold and the small-diameter section of the bottom mold; the moxibustion tool body is not shown in the figure). The feeding mold is as follows... Figure 7 As shown, the lower surface 19 of the feeding mold is attached to the upper surface of the middle mold and the feeding cylinder is aligned with the middle cylinder. Then, the individual moxa wool blocks in the feeding cylinder 20 of the feeding mold are pressed into the middle cylinder of the middle mold, and then the feeding mold is moved.
[0050] Step 5. Pressing the moxa wool: After assembling the middle mold and the bottom mold, the lower mold, which together form the lower mold, is moved below the upper mold. The upper mold core of the upper mold is pressed into the middle cylinder, and then heated and pressurized.
[0051] Step 6. Separate the upper mold from the middle mold to remove the lower mold as a whole. Then separate the middle mold from the bottom mold and remove the cylinder containing the moxa wool. The middle mold and the bottom mold are recycled and reused.
[0052] Step 7. Install the base of the tubular moxibustion device onto the bottom of the cylinder containing moxa wool to obtain the tubular moxibustion device.
[0053] Furthermore, the arrangement, quantity, and position of the feed cylinder, upper mold core, middle cylinder, and bottom mold are all consistent. This ensures that processes such as pressing individual moxa wool blocks from the feed cylinder into the middle cylinder of the middle mold, assembling the middle mold and the bottom mold, and pressing the upper mold core into the middle cylinder to compress the moxa wool can be achieved.
[0054] Furthermore, the height of the moxibustion device's body is greater than the height of the large-diameter section of the bottom mold, while the height of the small-diameter section is less than the sum of the heights of the large-diameter section and the middle cylinder. Simultaneously, the height of the moxibustion device's body after being inserted into the groove of the bottom mold is equal to the height of the small-diameter section, resulting in the optimal shape of the product.
[0055] Furthermore, the spring below the upper mold is used to assist in separating the upper mold from the lower mold in step 6.
[0056] Furthermore, the tube containing pressed moxa wool obtained in step 6 can be further coated with adhesive at the bottom of the base, fitted with a lid on the top, packaged, and sealed.
[0057] Compared with existing technologies, the beneficial effects of this technical solution are as follows:
[0058] 1. The initially compressed moxa wool is transferred to the extrusion device. The outlet of the extrusion device is shaped to match the cross-section of the moxibustion device cylinder. The moxa wool extruded from the outlet of the extrusion device is then cut into individual moxa wool blocks of uniform length, weighed, and the individual moxa wool blocks that meet the preset standard weight range are placed into the feeding cylinder of the feeding mold. This achieves semi-automation of the weighing process. Individual moxa wool blocks cannot enter the feeding cylinder before meeting the preset standard weight, which solves the problem of high defect rate caused by insufficient moxa wool weight in the original automatic feeding device. At the same time, it saves a lot of manpower and improves work efficiency compared to purely manual moxa wool collection.
[0059] II. The lower mold consists of a middle mold and a bottom mold. The diameter of the large-diameter section of the bottom mold is the same as the diameter of the middle cylinder of the middle mold, and the height of the small-diameter section is less than the sum of the heights of the large-diameter section and the middle cylinder. The moxa wool to be pressed is limited by the middle cylinder of the middle mold and the bottom mold. The upper mold core is only used to provide pressure for pressing the moxa wool, thus ensuring that the moxibustion device body does not directly contact the upper mold during the pressing process. Even if the upper and lower molds are not aligned, the middle mold will be subjected to the force of the upper mold core first, giving the operator an opportunity to readjust the position and increasing the fault tolerance. This solves the problem in existing technologies where the upper mold restricts the position of the moxa wool, causing the upper mold core to directly damage the moxibustion device body if it is slightly misaligned.
[0060] Third, without the limiting structure of the ring section and the retaining spring, when the pressing of moxa wool is finished, some of the middle cylinder will inevitably be attached to the upper mold core, the middle cylinder will detach from the middle cylinder mounting hole, and it will not be able to be moved away with the middle mold. The operator has to reach under the press to pull off the middle cylinder attached to the upper mold core, and then put the middle cylinder back into the middle cylinder mounting hole with the middle cylinder facing down. The operation is cumbersome and has safety hazards.
[0061] Therefore, a limiting structure was designed for the middle cylinder of the mold. The annular section and the retaining spring work together to prevent the middle cylinder from moving up and down relative to the middle cylinder mounting hole, thus avoiding the problem that the middle cylinder is still attached to the upper mold core after the moxa wool is pressed and cannot be moved away with the middle mold.
[0062] Fourth, a spring was added between the upper mold core and the upper mold to assist in separating the upper mold from the lower mold.
