Description

Technical Field

[0001] The invention relates to the technical field of insole pressing, in particular to a pressing machine for preparing thin sheets for insoles by pressing hemp fiber powder and a use method thereof. Background Art

[0002] As people's requirements for insole performance continue to increase, finding new environmentally friendly, comfortable and functional insole materials has become a hot topic in current research. As a natural material, hemp fiber has the advantages of antibacterial, good moisture absorption and high strength, and has broad application prospects in the field of insole manufacturing.

[0003] The pressing equipment usually includes a hopper, a conveying pipeline, a conveying motor, a transmission device, a sensor, and a controller. At present, there are many technical difficulties in the process of using hemp fiber powder to press and prepare thin sheets for insoles. First, in the raw material filling process, the hemp fiber powder is unevenly distributed in the mold, and local density differences will appear during pressing, resulting in uneven pressure distribution in the mold; areas with more fiber powder will be subjected to greater pressure and form higher density agglomerates, while areas with less fiber powder are relatively loose, which makes the overall strength of the sheet inconsistent, the surface flatness is poor, the antibacterial and deodorizing properties are unstable, the elasticity is uneven, and the dimensional stability is poor, which not only affects the quality and performance of the insole, but also reduces production efficiency and increases the scrap rate;

[0004] At the same time, the hemp fiber powder will also be blocked due to its powdery characteristics during the injection process; on the one hand, if the fineness of the hemp fiber powder is relatively small in the range of 100-1000 mesh, it is easy to accumulate in narrow parts such as the discharge port, pipeline or mold entrance of the injection equipment, thereby forming a blockage; on the other hand, the powdered hemp fiber powder may generate static electricity during the flow process, causing the powders to adsorb each other, and after gathering together, it is also easy to block the channel; the blockage will interrupt the injection process, affect the production progress, and even cause damage to the injection equipment. In addition, the blockage will cause uneven injection of the fiber powder, which will further affect the quality of the pressed insole sheet;

[0005] In addition, with the diversification of people's demands for insoles, the demand for insoles of different specifications and thicknesses in the market is increasing. In the prior art, when hemp fiber powder is used to press and prepare thin sheets for insoles, if insoles of different specifications or thicknesses are to be manufactured, the powder filling conveying equipment needs to be adjusted and set. However, there are many problems with this adjustment setting. First, non-professional adjusters need to undergo special training before they can operate the equipment, which brings a high threshold to equipment operation. On the one hand, training takes time and costs, affecting the improvement of production efficiency. On the other hand, even after training, non-professionals may still make incorrect settings during operation, resulting in the production of insoles that do not meet the requirements and increasing the scrap rate. Moreover, frequent adjustment settings will affect the stability and reliability of the equipment. Each adjustment will introduce new uncertainties, such as inaccurate parameter settings and increased wear of equipment components, which will not only affect the quality of the insoles, but also shorten the service life of the equipment and increase repair and maintenance costs.

[0006] Therefore, we proposed a pressing machine and a method for using hemp fiber powder to press and prepare thin sheets for insoles to solve the above problems. Summary of the invention

[0020] The method for using a pressing machine for pressing insole sheets with hemp fiber powder comprises the following steps: raw material preparation, additive mixing, mold preparation, filling and pre-pressing, formal pressing, demoulding and post-processing, quality inspection, and quality inspection;

[0021] The raw material preparation includes: selecting high-quality hemp fiber, crushing it, and obtaining hemp fiber powder; screening, removing impurities and oversized particles, and ensuring uniform powder fineness;

[0022] The additive mixing comprises: adding an appropriate amount of adhesive, antibacterial agent and other additives to the hemp fiber powder according to the requirements, mixing them thoroughly to improve the performance of the insole sheet, and loading the mixed powder into the rotating column B;

[0023] The mold preparation includes: preparing a pressing mold that matches the shape and size of the insole, and the surface of the pressing mold needs to be smooth and flat to ensure that the surface quality of the pressed sheet is good;

[0024] The filling and pre-pressing include: by rotating the rotating column B, when the discharge port and the discharge port coincide, the mixed powder is evenly filled into the pressing mold, and the filling amount is controlled according to the required sheet thickness; and then pre-pressing is performed to initially expel the air in the powder to make the powder more compact;

[0025] The formal pressing comprises: placing the pressing mold filled with hemp fiber powder into a pressing machine, and performing formal pressing according to set pressure, temperature and time; the pressure should be moderate to ensure that the density and strength of the sheet meet the requirements; the temperature can be adjusted according to the characteristics of the adhesive to promote the curing of the adhesive; the pressing time should be long enough to ensure the molding quality of the sheet;

[0026] The demoulding and post-processing includes: after the pressing is completed, the pressed mold is cooled to a safe temperature, and then the demoulding operation is performed to take out the insole sheet; the sheet is trimmed and polished to make its edges neat and the surface smooth;

[0027] The quality inspection includes: conducting quality inspection on the prepared insole sheets, including testing of thickness, density, strength, and antibacterial performance indicators to ensure compliance with relevant standards and requirements.

[0028] Compared with the prior art, the present invention provides a pressing machine for preparing thin sheets for insoles by pressing hemp fiber powder, which has the following beneficial effects:

[0029] 1. The present invention designs the surrounding groove to be composed of a curved groove surrounding the rotating column A and a surrounding straight groove, and the curved groove occupies three quarters of the annular surface of the rotating column A, and the straight groove occupies one quarter of the annular surface of the rotating column A. The above design can make the transverse moving member vibrate during the rapid reset of the transverse moving member after the rotating columns A and B rotate and evenly move the feeding. The above rapid return and reset means that the next feeding operation can be started faster, reducing the waiting time, thereby improving the cycle speed of the entire production process, and more feeding and pressing processes can be completed in the same time, significantly improving production efficiency;

[0030] At the same time, during the rapid resetting of the transverse moving member, the vibration action can cause the statically charged object to undergo a slight displacement and movement. In this process, the charged particles that were originally adsorbed together can be separated due to the vibration; for the hemp fiber powder adsorbed on the conveying pipeline, that is, on the inner wall of the rotating column B, the vibration can loosen the powder particles and reduce the close contact between the particles, thereby reducing the static adsorption force, thereby avoiding the static electricity generated by the powdered hemp fiber powder during the flow process due to friction electrification, separation electrification, etc. The static electricity causes the powder particles to adsorb to each other to form aggregates, and these aggregates increase or adhere to the channel wall, which can easily lead to blockage of the channel.

[0031] 2. The present invention adopts a design that the guide limiting member is composed of a rotating piece, a column and a rotating feedback piece. In addition to the auxiliary rotating column A rotating when the quality stabilization and efficiency improvement component feeds the mixed powder, the rotating piece on the guide limiting member rubs against the side wall of the surrounding groove and rotates thereby. This design of observing the rotation of the rotating piece of the guide limiting member to feedback whether the feeding is carried out at a uniform speed can bring the following beneficial effects:

[0032] Real-time monitoring of uniformity: By observing the speed of the rotating parts, the rotation of the pusher can be understood in real time, so as to judge whether the hemp fiber powder is evenly distributed; uneven distribution can be discovered in time and adjusted to ensure the stable quality of the insole sheet;

[0033] Improve product quality and prevent equipment failure: Accurately controlling the uniformity of placement helps ensure that the pressed insole sheets have better consistency in density, strength, antibacterial properties, etc.; reduce local quality problems caused by uneven placement and improve the overall quality of the product;

[0034] Enhanced production controllability: Make the production process more controllable. Operators can make precise adjustments to production based on the feedback from rotating parts to ensure that each batch of products meets high quality standards.

[0035] 3. The present invention adopts the design of a quality-stabilizing and efficiency-improving component. In the raw material filling process, the feeding rotating column B is designed to rotate and feed the materials. This can ensure that the hemp fiber powder and the additives in the rotating column B are still in a mixing action during the feeding process. At the same time, the rotating feeding action can effectively ensure the smoothness of the powder being poured from the discharge port to the pressing module. This design can effectively ensure the uniform distribution of the hemp fiber powder when it is fed into the pressing module, and can effectively avoid the occurrence of local density differences during pressing, which leads to uneven pressure distribution in the pressing module; it effectively avoids the situation that the area with more hemp fiber powder will be subjected to greater pressure and form a higher density agglomeration, while the area with less fiber powder is relatively loose, resulting in inconsistent overall strength of the thin slice, and truly and effectively achieves good flatness of the pressed surface, stable antibacterial and deodorizing properties, uniform elasticity, good dimensional stability, improved quality and performance of the insole, optimized production efficiency, and reduced scrap rate.

[0036] 4. The present invention converts the adjustment of the amount of each discharge into the adjustment of the size of the air inlet through the coordinated design of the air inlet and the blocking piece. This design does not require professional training. Unlike the traditional conveying equipment control method that requires professionals to perform complex numerical settings, the operation of adjusting the size of the air inlet by pulling is extremely simple. Any operator can quickly get started without special training, which greatly reduces the threshold for equipment operation. Moreover, this fast adjustment operation method can adjust the amount of conveyed powder in a short time without cumbersome parameter input and calculation process, thereby improving production efficiency and meeting the rapid production needs of insoles of different specifications.

[0037] At the same time, it enhances production flexibility; operators can adjust the size of the air inlet at any time according to the actual production situation, adjust the powder delivery volume in real time, and thus flexibly control the thickness and specifications of the insole; whether it is small batch customization or large-scale production, it can be easily coped with; it can adapt to different needs; for different customers' diverse requirements for insole specifications and thickness, this design can respond quickly without complicated equipment modification or reprogramming, which improves the adaptability and flexibility of production.

[0038] 5. The present invention is different from the prior art in that when hemp fiber powder is used to press and prepare thin sheets for insoles, if insoles of different specifications or thicknesses are to be manufactured, the powder filling conveying equipment needs to be adjusted and set; however, non-professional adjusters need to undergo special training before they can operate the equipment, which brings a high threshold to equipment operation, and the training requires time and cost, which affects the improvement of production efficiency; the simple and intuitive operation of the multi-specification and multi-thickness adapter components will not result in incorrect settings even if non-professionals operate them, which will cause the produced insoles to not meet the requirements, thereby reducing the scrap rate; moreover, only the adjustment setting of the transversely movable blocking piece will not affect the stability and reliability of the equipment, which is different from the existing adjustment, in which new uncertain factors are introduced in each adjustment, such as inaccurate parameter settings, increased wear of equipment components, etc., thereby improving the production quality of the insoles, ensuring the service life of the equipment, and reducing the repair and maintenance costs.

[0072] For further examples, please refer to Figure 1 , Figure 2 , Figure 5 , Figures 6 to 10 As shown:

[0073] The function of the multi-specification and multi-thickness adaptor 5 is to adapt to different shoe sizes and adjust the insole sheets according to the different thickness requirements during the pressing process; the multi-specification and multi-thickness adaptor 5 includes a magnetic ring 501 fixedly connected to the side wall of the transverse member 404, a magnetic plug 502 is slidably connected to the inner cavity of the rotating column A405, a one-way valve 503 and a dividing plate A504 are fixedly connected to the inner cavity of the rotating column A405, a dividing plate B505 is fixedly connected to the inner cavity of the rotating column B407, and a return spring 506 is fixedly connected to the dividing plate B505.

[0084] Further examples:

[0085] The method for using a pressing machine for pressing insole sheets with hemp fiber powder comprises the following steps: raw material preparation, additive mixing, mold preparation, filling and pre-pressing, formal pressing, demoulding and post-processing, quality inspection, and quality inspection;

[0086] Raw material preparation includes: selecting high-quality hemp fiber, crushing it to obtain hemp fiber powder; screening to remove impurities and oversized particles to ensure uniform powder fineness;

[0087] Additive mixing includes: adding appropriate amount of adhesive, antibacterial agent and other additives to the hemp fiber powder according to the demand, mixing thoroughly to improve the performance of the insole sheet, and loading the mixed powder into the rotating column B407;

[0088] The mold preparation includes: preparing a pressing mold 202 that matches the shape and size of the insole, and the surface of the pressing mold 202 needs to be smooth and flat to ensure that the surface quality of the pressed sheet is good;

[0089] Filling and pre-pressing include: by rotating the rotating column B407, when the discharge port 408 and the discharge port 413 coincide, the mixed powder is evenly filled into the pressing mold 202, and the filling amount is controlled according to the required sheet thickness; and then pre-pressing is performed to initially expel the air in the powder to make the powder more compact;

[0090] The formal pressing includes: placing the pressing mold 202 filled with hemp fiber powder into the pressing machine, and performing formal pressing according to the set pressure, temperature and time; the pressure should be moderate to ensure that the density and strength of the sheet meet the requirements; the temperature can be adjusted according to the characteristics of the adhesive to promote the curing of the adhesive; the pressing time should be long enough to ensure the molding quality of the sheet;

[0091] Demolding and post-processing include: after the pressing is completed, the pressed mold 202 is cooled to a safe temperature, and then the demoulding operation is performed to remove the insole sheet; the sheet is trimmed and polished to make its edges neat and the surface smooth;

[0092] Quality inspection includes: quality inspection of the prepared insole sheets, including testing of thickness, density, strength, and antibacterial performance indicators to ensure compliance with relevant standards and requirements.

[0093] Everything in the above example works like this:

[0094] In the initial state:

[0095] The spring body 403 is not compressed, the discharge port 408 does not overlap with the discharge port 413, the magnetic attraction ring 501 is not on the same vertical plane as the magnetic plug 502, and the return spring 506 is in a normal relaxed state and is not stretched.

[0096] The following is the working process of the quality stabilization and efficiency improvement component 4:

[0097] When in use, the moving body 401 will be driven to reciprocate on the driving rail 3 to assist in the delivery of the powder to be pressed. Specifically, the driving of the telescopic rod can be implemented to move the moving body 401 on the driving rail 3. When in use, the driving wheel group 409 in the starting device, after the driving wheel group 409 is started, the rotating column B407 fixedly connected to the driven gear of the driving wheel group 409 will rotate with the rotating column A405 at one end. The surrounding groove 406 provided on the rotating column A405 includes a curved groove surrounding the rotating column A405 and a linear groove surrounding the rotating column A405; and the curved groove occupies three quarters of the annular surface of the rotating column A405, and the linear groove occupies one quarter of the annular surface of the rotating column A405. Therefore, when the rotating column A405 rotates, the transverse moving member 404 originally sleeved on the rotating column A405 will move guided by the guide rod 402 under the action of the guide limiting member 410 and the surrounding groove 406. During the rotation of the spring body 403, the spring body 403 is compressed, and the rotating piece in the guide limiting member 410 is located in the curved groove of the surrounding groove 406. Furthermore, as the rotating column B407 continues to rotate with the rotating column A405 fixedly connected, the guide limiting member 410 on the transverse member 404 will slide from the curved groove of the surrounding groove 406 to the linear groove. Since it is known that the curved groove occupies three quarters of the annular surface of the rotating column A405, and the linear groove occupies one quarter of the annular surface of the rotating column A405, the transverse member 404 at this time will be compressed in the spring body 403. 03 is reset and quickly returns to the initial state; further, as the rotating column B407 continues to rotate with the rotating column A405, the above-mentioned action will be repeated, that is, the rotating column B407 and the rotating column A405 will continue to rotate, and the transverse moving member 404 set on the rotating column A405 will perform transverse linear reciprocating motion; further, when the powder is added at a normal speed, its driving speed or moving distance can be changed, so that under the condition of a certain amount of powder added, insole sheets of different shoe sizes or different thicknesses can be obtained;

[0098] Furthermore, during the rotation of the rotating column B407, the collar 412 fixedly mounted on the outer end of the rotating column B407 by the support rod 411 will intermittently overlap with the discharge port 408 opened on the rotating column B407 during the rotation of the rotating column B407, thereby putting the powder to be pressed in the rotating column B407 into the pressing mold 202;

[0099] Furthermore, the present invention designs the surrounding groove 406 to be composed of a curved groove surrounding the rotating column A405 and a surrounding straight groove, and the curved groove occupies three quarters of the annular surface of the rotating column A405, and the straight groove occupies one quarter of the annular surface of the rotating column A405. The above design can make the transverse member 404 vibrate during the rapid reset of the transverse member 404 after the rotating columns A405 and B407 rotate and uniformly move the feeding. The above rapid return and reset means that the next feeding operation can be started faster, reducing the waiting time, thereby improving the cycle speed of the entire production process, and more feeding and pressing processes can be completed in the same time, significantly improving production efficiency.

[0100] At the same time, during the rapid resetting of the transverse member 404, the vibration action can cause the statically charged object to undergo a slight displacement and movement. In this process, the charged particles that were originally adsorbed together can be separated due to the vibration; for the hemp fiber powder adsorbed on the conveying pipeline, that is, the inner wall of the rotating column B407, the vibration can loosen the powder particles and reduce the close contact between the particles, thereby reducing the static adsorption force, thereby avoiding the powdered hemp fiber powder from generating static electricity due to frictional electrification, separation electrification, etc. during the flow process. The static electricity causes the powder particles to adsorb to each other to form aggregates, which increase in size or adhere to the channel wall, easily leading to blockage of the channel.

[0101] Furthermore, the present invention is designed by the guide limiter 410 to be composed of a rotating piece, a column and a rotating feedback piece. In addition to the auxiliary rotating column A405 rotating when the quality stabilization and efficiency improvement component 4 feeds the mixed powder, the rotating piece on the guide limiter 410 will rub against the side wall of the surrounding groove 406 and rotate accordingly. Please refer to the attached Figure 6 And attached Figure 7 This design of observing the rotation of the rotating piece of the guide limiter 410 to provide feedback on whether the delivery is carried out at a uniform speed can monitor the uniformity in real time: by observing the speed of the rotating parts, the rotation of the push piece 507 can be understood in real time, so as to judge whether the delivery of the hemp fiber powder is uniform; the uneven delivery can be discovered in time and adjusted to ensure the stable quality of the insole slices; improve product quality and prevent equipment failure: accurately grasping the uniformity of delivery helps to ensure that the pressed insole slices have better consistency in density, strength, antibacterial properties, etc.; reduce local quality problems caused by uneven delivery and improve the overall quality of the product; enhance production controllability: make the production process more controllable, and the operator can make precise adjustments to the production based on the information fed back by the rotating parts to ensure that each batch of products can meet higher quality standards.

[0102] Furthermore, the present invention adopts the design of the quality stabilization and efficiency improvement component 4. In the raw material filling process, the feeding rotating column B407 is designed to rotate and feed the materials. This can ensure that the hemp fiber powder and the additives in the rotating column B407 are still in a mixing action during the feeding process. At the same time, the rotating feeding action can effectively ensure the smoothness of the powder being poured from the discharge port 408 to the pressing module 202. This design can effectively ensure the uniform distribution of the hemp fiber powder when it is fed into the pressing module 202, and can effectively avoid the occurrence of local density differences during pressing, resulting in uneven pressure distribution in the pressing module 202; it effectively avoids the situation that areas with more hemp fiber powder will be subjected to greater pressure and form higher density agglomerates, while areas with less fiber powder are relatively loose, resulting in inconsistent overall strength of the thin slices. It truly and effectively achieves good flatness of the pressed surface, stable antibacterial and deodorizing properties, uniform elasticity, and good dimensional stability, thereby improving the quality and performance of the insole, optimizing production efficiency, and reducing the scrap rate.

[0103] Please refer to the above working process Figures 1 to 6 , Fig.10 .

[0104] The following is the working process of the multi-specification and multi-thickness adapter component 5:

[0105] Furthermore, during the linear reciprocating motion of the transverse member 404 on the rotating column A405, the transverse member 404 will move with the magnetic ring 501 fixedly connected to the rear side. Since it is known that the magnetic ring 501 is mainly used in conjunction with the magnetic plug 502, when the magnetic ring 501 moves, the magnetic plug 502 can be driven by magnetism to move in the inner cavity of the rotating column A405. Therefore, during the linear reciprocating motion of the transverse member 404, the magnetic plug 502 in the rotating column A405 will also perform linear reciprocating motion. During the movement of the magnetic plug 502, the magnetic plug 502 will enter the rotating column A405 through the air inlet 509. The air in 405 is pushed into the temporary gas storage chamber composed of the one-way valve 503 and the partition plate A504 through the one-way valve 503, and is transferred to the working chamber composed of the partition plate A504 and the partition plate B505 through the connecting pipe 508. As the gas enters, the gas pushes the partition plate B505 to move in the rotating column B407, and the return spring 506 is stretched at this time. Further, as the push plate 507 moves, the powder to be pressed in the rotating column B407 is discharged through the discharge port 408 opened thereon, and falls into the pressing mold 202.

[0106] Furthermore, by adjusting the opening size of the air inlet 509, the amount of gas entering the working chamber composed of the partition plate B505 and the push plate 507 can be changed. For details, please refer to the attached Fig.10, the distance between the rightmost end of the air inlet 509 blocked by the blocking piece 511 and the one-way valve 503 is the amount of gas that can be pushed and transferred, because the gas is initially pushed by the magnetic plug 502, and the remaining distance, that is, the gas from the rightmost end of the air inlet 509 blocked by the blocking piece 511 to the magnetic plug 502 will leak out from the air inlet 509 during the pushing; that is, the larger the opening of the air inlet 509, the less gas amount is pushed and transferred by the magnetic plug 502, and the moving distance of the push piece 507 that is indirectly forced to move by the gas is also shorter, and the amount of powder to be pressed that is pushed and transferred will also be less;

[0107] Further, for adjusting the size of the air inlet 509, please refer to the attached Figure 7 Specifically, the operator can rotate the screw 512 to drive the blocking piece 511 threadedly connected thereto to move horizontally with the horizontal groove 510 as a sliding track, so as to adjust the opening size of the air inlet 509;

[0108] Furthermore, the present invention converts the adjustment of the amount of material discharged each time into the adjustment of the size of the air inlet 509 through the coordinated design of the air inlet 509 and the blocking piece 511, and this design does not require professional training; unlike the traditional conveying equipment control method that requires professionals to perform complex numerical settings, the operation of adjusting the size of the air inlet 509 by pulling is extremely simple, and any operator can quickly get started without special training, which greatly reduces the threshold for equipment operation; and this fast adjustment operation method can adjust the amount of conveyed powder in a short time without cumbersome parameter input and calculation process, thereby improving production efficiency and meeting the rapid production needs of insoles of different specifications;

[0109] At the same time, the production flexibility is enhanced; the operator can adjust the size of the air inlet 509 at any time according to the actual production situation, and adjust the powder delivery volume in real time, so as to flexibly control the thickness and specifications of the insole; whether it is small batch customization or large-scale production, it can be easily handled; it can adapt to different needs; for different customers' diverse requirements for insole specifications and thicknesses, the design can respond quickly without complicated equipment modification or reprogramming, thereby improving the adaptability and flexibility of production.

[0110] Furthermore, the present invention is different from the prior art in that when hemp fiber powder is used to press and prepare thin sheets for insoles, if insoles of different specifications or thicknesses are to be manufactured, the powder filling conveying equipment needs to be adjusted and set; but non-professional adjusters need to undergo special training before they can operate the equipment, which brings a high threshold to equipment operation, and the training requires time and cost, which affects the improvement of production efficiency; the simple and intuitive operation of the multi-specification and multi-thickness adapter component 5 will not result in incorrect settings even if non-professionals operate it, which will cause the produced insoles to not meet the requirements, thereby reducing the scrap rate; moreover, only the adjustment setting of the transversely moving blocking piece 511 will not affect the stability and reliability of the equipment, which is different from the existing adjustment, in which new uncertain factors are introduced in each adjustment, such as inaccurate parameter settings, increased wear of equipment components, etc., thereby improving the production quality of the insoles, ensuring the service life of the equipment, and reducing repair and maintenance costs.
