Description

Technical Field

[0001] The present invention relates to the technical field of yoga mat production, and specifically relates to a forming device for producing a highly tough and wear-resistant yoga mat. Background Art

[0002] With the improvement of living standards, people pay more and more attention to their own health. Many people who practice yoga or indoor fitness will use yoga mats. The mainstream yoga mat materials in China are thermoplastic highly tough and wear-resistant materials such as TPE, PVC, and PU.

[0003] At present, the production and manufacturing of yoga mats generally adopt an integral forming method. The Chinese invention patent with the publication number of CN112847606B discloses a forming device for a highly tough and wear-resistant yoga mat and its processing technology. The forming device includes a conveying member for conveying the yoga mat, and an extrusion member is provided on the conveying member. The extrusion member makes the yoga mat closely fit on the conveying member for transmission. A first cutting member for cutting the width direction of the yoga mat is provided on the conveying member, and a second cutting member for cutting the length direction of the yoga mat is provided at one end of the conveying member. One end of the second cutting member is fixedly connected to the conveying member, and a second supporting member is provided at the other end. A traction member for pulling the yoga mat is provided on the second supporting member, a fixing member for pressing and fixing the yoga mat is provided on the second supporting member, and a cutting arm for cutting and forming the yoga mat is provided on the second supporting member; it can realize the integral forming of the yoga mat, promote the automated production process of the yoga mat, simplify the production process, reduce the investment in labor costs, be beneficial to improving production efficiency, and meet the market demand.

[0004] However, the yoga mat integrally formed by this forming device and its processing technology does not have the functions of air permeability and sweat discharge. During the exercise process, users will inevitably discharge heat and sweat. If the ordinary yoga mat does not wipe off the sweat in time, its anti-slip performance will be reduced, and the heat discharged by the user will not dissipate in time, which will also reduce the comfort of the user using the yoga mat. Therefore, the yoga mat without the functions of air permeability and sweat discharge is not user-friendly.

[0005] In summary, how to make the yoga mat have the functions of air permeability and sweat discharge during the production and manufacturing process of the yoga mat is a problem that needs to be solved by those skilled in the art at present. Summary of the Invention

[0006] In order to make the yoga mat have the functions of air permeability and sweat discharge during the production and manufacturing process of the yoga mat, the present invention provides a forming device for producing a highly tough and wear-resistant yoga mat.

[0007] The technical solution of the present invention is as follows:

[0008] The present invention provides a forming device for producing a highly tough and wear-resistant yoga mat, which includes a mounting frame.

Air holes corresponding to the second mounting holes are provided on the side wall of the horizontal pipe corresponding to the thick side of the eccentric camshaft. A pressure relief valve is provided between the air outlet end of the air cylinder and the horizontal pipe. An air inlet is provided at a position near the lower part of the air cylinder.

[0012] Further, both the first mounting cylinder and the second mounting cylinder are made of materials with good electrical conductivity, and the first mounting cylinder and the second mounting cylinder are respectively connected to an external power supply. The push rod and the needle are made of electrothermal alloy materials with good structural strength. Both the first mounting cylinder and the second mounting cylinder are drivingly connected to the transmission component.

[0013] Further, the transmission assembly includes a driving shaft. Two driving shafts are drivingly connected to the output shafts at both ends of the power device. On the outer sides of the two driving shafts away from the power device, a first driving gear and a second driving gear fixedly connected thereto are arranged in parallel. On the outer side of the first driving gear, a first driven gear capable of meshing with it is provided. The first driven gear is rotationally connected to the transverse shaft through a bearing, and the first driven gear is fixedly connected to the outer end of the first mounting cylinder. On the outer side of the first driven gear, a second driven gear meshing and driving with it is provided. The second driven gear is rotationally connected to the transverse pipe through a bearing, and the second driven gear is fixedly connected to the outer end of the second mounting cylinder. On the outer side of the second driving gear, a rack meshing and driving with it is provided. Between the lower end of the rack and the mounting frame, a first return spring is provided. One end of the first return spring is fixedly connected to the rack, and the other end of the first return spring is fixedly connected to the mounting frame. The rack is drivingly connected to the pneumatic assembly.

[0014] Further, on the outer sides of the first driving gear and the second driving gear, toothless portions are correspondingly provided. The β angle corresponding to the tooth portion of the first driving gear is not greater than the α angle corresponding to the toothless portion of the second driving gear.

[0015] Further, between the ejector rod and the first mounting cylinder, a third return spring is provided. One end of the third return spring is fixedly connected to the side of the ejector rod near the inner end, and the other end of the third return spring is fixedly connected to the side of the first mounting hole near the outer end of the second mounting cylinder.

[0016] Further, between the pin and the second mounting cylinder, a second return spring is provided. One end of the second return spring is fixedly connected to the side of the pin near the inner end, and the other end of the second return spring is fixedly connected to the side of the second mounting hole near the outer end of the second mounting cylinder.

[0017] Further, a tapered hole is provided at the outer end of the ejector rod. A blind hole is provided at the bottom of the tapered hole. Inside the blind hole, a conductive block electrically slidingly connected thereto is provided. A relief groove corresponding to the pin is provided on the outer end face of the conductive block. Between the inner end face of the conductive block and the bottom surface of the blind hole, a fourth return spring is provided.

[0018] The beneficial effects achieved by the present invention are as follows:

[0019] During the use of the present invention, the yoga mat to be processed is placed on the conveyor of one end of the mounting frame. When the conveyor is turned on, the yoga mat to be processed will be conveyed between the first mounting cylinder and the second mounting cylinder. Then, when the power device is turned on, after the power device starts, it will drive the first mounting cylinder and the second mounting cylinder to rotate synchronously through the transmission assembly. As the first mounting cylinder rotates, the first mounting cylinder will drive the ejector rod to slide on the outside of the special-shaped camshaft. When the ejector rod slides to the thick side of the special-shaped camshaft, the ejector rod will extend out of the outside of the first mounting cylinder. At the same time, the second mounting cylinder will drive the corresponding needle to rotate to between the air hole and the extended ejector rod. At this time, the transmission assembly will drive the air pressure assembly to generate air pressure, and the air pressure will push the needle downward through the air hole. The needle will pierce the yoga mat and contact the ejector rod. After the ejector rod contacts the needle, it will connect to an external power supply and generate heat. After the ejector rod and the needle generate heat, they will perform local thermal shaping on the yoga mat. The local strength of the yoga mat after thermal shaping will increase, and it is beneficial to improve its wear resistance.

[0020] The transmission assembly of the present invention ingeniously combines gear transmission and pneumatic transmission. During the working process, the gear meshing transmission adopted has an accurate and stable transmission ratio, which can effectively ensure the stability and accuracy of the forming process of the yoga mat. At the same time, it cooperates with pneumatic transmission to perform piercing and forming on the yoga mat, making the yoga mat have air permeability and water permeability in terms of structure. Moreover, no-tooth parts are correspondingly provided on the outside of the first driving gear and the second driving gear. The β angle corresponding to the tooth part of the first driving gear is not greater than the α angle corresponding to the no-tooth part of the second driving gear. That is, when the tooth part of the first driving gear meshes with the first driven gear, the tooth part of the second driving gear does not mesh with the rack. This design can avoid motion interference during the working process of the transmission assembly and ensure the feasibility and stability of the present invention during the working process.

[0021] During the operation of the present invention, after the pin pierces the yoga mat downward, the tip of the pin will insert into the inside of the avoidance groove. The avoidance groove can protect the tip of the pin, that is, replace the point contact between the pin and the conductive block with a surface contact, so as to avoid damage to the pin caused by excessive temperature at a single point. At the same time, the fourth return spring can convert the rigid contact between the pin and the ejector rod into an elastic contact, effectively avoiding damage to the tip of the pin due to impact during operation. This design further ensures the safety and stability of the pin during operation. After the pin and the ejector rod are energized and heated, the yoga mat will be locally heat-shaped according to the shapes of the pin, the ejector rod and the tapered hole. As a result, a groove corresponding to the outside of the ejector rod will be formed on the bottom surface of the yoga mat, and fine holes corresponding to the outside of the pin will be formed on the top surface of the yoga mat. A tapered through hole extending downward corresponding to the shape of the tapered hole will be formed between the groove and the fine holes. The downward-extending tapered through hole can allow sweat or hot air generated by the user during exercise to penetrate from the top surface of the yoga mat to the bottom surface, rather than from the bottom surface of the yoga mat to the top surface. This design can effectively discharge the sweat and heat generated by the user during exercise, further increasing the comfort of the user when using the yoga mat.

[0022] In summary, the overall structure of the present invention is simple and ingenious. Through the combination of gear clearance transmission, pneumatic transmission and electrothermal principle, local thermal shaping can be carried out on the yoga mat during the production and manufacturing process of the yoga mat, so that the yoga mat has the functions of air permeability and sweat discharge. The yoga mat processed and formed by the present invention is very suitable for people who practice yoga or do indoor fitness. The present invention has positive application and popularization value.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0036] Such as Figure 1As shown in the figure, the present invention provides a molding device for producing a highly tough and wear-resistant yoga mat, which includes a mounting frame 1. Transmission members 2 are installed at both ends of the mounting frame 1. The transmission members 2 belong to the prior art and various transmission devices capable of transmitting yoga mats can be used. The structural principle thereof will not be elaborated herein. A molding assembly installed on the frame 1 is provided between the two transmission members 2. During the working process, after the transmission member 2 at one end of the mounting frame 1 transmits the yoga mat to the molding assembly for molding, the transmission member 2 at the other end of the mounting frame 1 will transmit the molded yoga mat to the outside.

[0037] As Figure 2 , 3As shown in FIGS. 6 and 7, the forming assembly includes a power device 3 which is fixedly installed on the mounting frame 1. The power device 3 can be a motor, an engine, etc. In this embodiment, a double-shaft extension motor is preferably adopted. The axis of the double-shaft extension motor is perpendicular to the length direction of the mounting frame 1. Transmission components are provided at both ends of the double-shaft extension motor and are in transmission connection therewith. A cross shaft 4 is fixedly connected to the mounting frame 1 corresponding to the transmission components. An irregular camshaft 5 is fixedly connected to the outside of the cross shaft 4. The surface of the irregular camshaft 5 is a smoothly transitional curved surface. A first mounting cylinder 6 rotatably connected to the cross shaft 4 is provided outside the irregular camshaft 5. A cross tube 7 fixedly connected to the mounting frame 1 is provided outside the first mounting cylinder 6. The cross tube 7 is correspondingly located on the thick side of the irregular camshaft 5. A second mounting cylinder 8 in sealed rotational connection with the cross tube 7 is provided outside the cross tube 7. A plurality of rows of first mounting holes 9 are annularly and uniformly distributed outside the first mounting cylinder 6. A push rod 10 in sliding electrical connection therewith is provided inside the first mounting holes 9. The other end of the push rod 10 contacts the surface of the irregular camshaft 5. A second mounting hole 11 is provided in the second mounting cylinder 8 corresponding to the first mounting holes 9. A pin 12 in sliding electrical connection therewith is provided inside the second mounting holes 11; an air pressure assembly in transmission connection with the transmission components is provided at the outer end of the cross tube 7. An air hole 13 corresponding to the second mounting hole 11 is provided in the side wall of the cross tube 7 on the thick side of the irregular camshaft 5. Both the first mounting cylinder 6 and the second mounting cylinder 8 are made of materials with good electrical conductivity, and the first mounting cylinder 6 and the second mounting cylinder 8 are respectively connected to an external power supply. The push rod 10 and the pin 12 are made of electrothermal alloy materials with good structural strength. Both the first mounting cylinder 6 and the second mounting cylinder 8 are in transmission connection with the transmission components; during the working process, after the power device is started, it will drive the first mounting cylinder 6 and the second mounting cylinder 8 to rotate synchronously through the transmission components. As the first mounting cylinder 6 rotates, the first mounting cylinder 6 will drive the push rod 10 to slide outside the irregular camshaft 5. When the push rod 10 slides to the thick side of the irregular camshaft 5, the push rod 10 will extend outside the first mounting cylinder 6. At the same time, the second mounting cylinder 8 will drive the corresponding pin 12 to rotate to between the air hole 13 and the extended push rod 10. At this time, the transmission components will drive the air pressure assembly to generate air pressure. The air pressure will push the pin 12 downward through the air hole 13. The pin 12 will pierce the yoga mat and contact the push rod 10. After the push rod 10 contacts the pin 12, it will connect to the external power supply and generate heat. After the push rod 10 and the pin 12 generate heat, they will perform local thermal shaping on the yoga mat. The local strength of the yoga mat after thermal shaping will increase, and it is beneficial to improve its wear resistance.

[0038] As Figure 2 、 4As shown in the figure, the transmission assembly includes a driving shaft 14. Two driving shafts 14 are drivingly connected to the output shafts at both ends of the power device 3. On the outer sides of the ends of the two driving shafts 14 away from the power device 3, a first driving gear 15 and a second driving gear 16 fixedly connected thereto are arranged in parallel. On the outer side of the first driving gear 15, a first driven gear 17 capable of meshing with it is provided. The first driven gear 17 is rotatably connected to the cross shaft 4 through a bearing. The first driven gear 17 is fixedly connected to the outer end of the first mounting cylinder 6. On the outer side of the first driven gear 17, a second driven gear 18 meshing and driving with it is provided. The second driven gear 18 is rotatably connected to the cross tube 7 through a bearing. The second driven gear 18 is fixedly connected to the outer end of the second mounting cylinder 8. On the outer side of the second driving gear 16, a rack 19 meshing and driving with it is provided. The rack 19 is drivingly connected to the air pressure assembly; during the working process, when the power device 3 drives the driving shaft 14 to rotate, the driving shaft 14 will drive the first driving gear 15 and the second driving gear 16 to rotate. The first driving gear 15 can drive the first driven gear 17 and the first mounting cylinder 6 to rotate. At the same time, the first driven gear 17 will drive the second driven gear 18 and the second mounting cylinder 8 to rotate; the second driving gear 16 can drive the rotating rack 19 to slide, and the rack 19 will drive the air pressure assembly to push the needle 12 downward. This design structure is simple and ingenious. The gear meshing drive adopted has an accurate and stable transmission ratio, which can effectively ensure the stability and accuracy of the yoga mat forming process. At the same time, it cooperates with the air pressure drive to puncture and form the yoga mat, so that the yoga mat has air permeability and water permeability in terms of structure, and can discharge the sweat and heat generated by the user during exercise, which is beneficial to increasing the comfort when using the yoga mat.

[0039] As Figure 2 , 4 shown, the air pressure assembly includes an air cylinder 20. The air cylinder 20 is fixedly installed on the outer side of the mounting frame 1. A piston 21 hermetically and slidably connected thereto is arranged inside the air cylinder 20. A piston rod 22 fixedly connected to the end of the piston 21 is provided at the end of the piston 21. The piston rod 22 is fixedly connected to the end of the rack 19. The air outlet end of the air cylinder 20 is hermetically and fixedly communicated with the cross tube 7; during the working process, the rack 19 can drive the piston rod 22 and the piston 21 to slide inside the air cylinder 20. When the piston 21 slides upward inside the air cylinder 20, the gas inside the air cylinder 20 will be compressed, and the compressed gas will push the needle 12 downward through the air hole 13, so that the needle 12 pierces the yoga mat to be processed.

[0040] As Figure 5As shown in the figure, in order to enable the ejector rod 10 and the pin 12 to better cooperate in the piercing forming process of the yoga mat, toothless parts are correspondingly provided on the outer sides of the first driving gear 15 and the second driving gear 16. The β angle corresponding to the tooth part of the first driving gear 15 is not greater than the α angle corresponding to the toothless part of the second driving gear 16. That is, when the tooth part of the first driving gear 15 meshes with the first driven gear 17, the tooth part of the second driving gear 16 does not mesh with the rack 19. This design can avoid movement interference during the operation of the transmission component, ensuring the feasibility and stability of the present invention during operation.

[0041] As Figure 2 shown in the figure, a first return spring 23 is provided between the lower end of the rack 19 and the mounting bracket 1. One end of the first return spring 23 is fixedly connected to the rack 19, and the other end of the first return spring 23 is fixedly connected to the mounting bracket 1. During operation, when the tooth part of the second driving gear 16 does not mesh with the rack 19, the first return spring 23 will drive the rack 19, the piston rod 22, and the piston 21 to move downward for reset. This design further ensures the feasibility and stability of the present invention during operation.

[0042] As Figure 2 shown in the figure, a pressure relief valve 31 is provided between the air outlet end of the air cylinder 20 and the cross pipe 7. An air inlet 32 is provided near the lower part of the outer side of the air cylinder 20. During operation, as the second driving gear 16 drives the rotating rack 19 to slide, the rack 19 will continuously drive the piston rod 22 and the piston 21 to slide inside the air cylinder 20. Therefore, the air pressure inside the air cylinder 20 will also continuously increase. When the air pressure inside the air cylinder 20 rises to the safety limit, the pressure relief valve 31 will automatically open. This design can not only ensure the safety during the pneumatic transmission process but also ensure that the pin 12 can continuously contact the ejector rod 10 during operation, thereby achieving the purpose of thermoplasticity. And when the first return spring 23 drives the rack 19, the piston rod 22, and the piston 21 to move downward for reset, the air inlet 32 can inhale air again. This design ensures the feasibility of the present invention during use.

[0043] As Figure 6 shown in the figure, a second return spring 24 is provided between the pin 12 and the second mounting cylinder 8. One end of the second return spring 24 is fixedly connected to the side of the pin 12 near the inner end, and the other end of the second return spring 24 is fixedly connected to the side of the second mounting hole 11 near the outer end of the second mounting cylinder 8. During operation, when the gas inside the air cylinder 20 is not compressed, the second return spring 24 will drive the pin 12 to contract inside the second mounting hole 11. This design further ensures the feasibility and stability of the present invention during operation.

[0044] As Figure 7As shown, a third return spring 25 is provided between the ejector rod 10 and the first mounting cylinder 6. One end of the third return spring 25 is fixedly connected to the side of the ejector rod 10 near the inner end, and the other end of the third return spring 25 is fixedly connected to the side of the first mounting hole 9 near the outer end of the second mounting cylinder 8. During the working process, when the first mounting cylinder 6 drives the ejector rod 10 to rotate, the third return spring 25 will push the ejector rod 10 to always slide on the surface of the special-shaped camshaft 5. This design further ensures the feasibility and stability of the present invention during the working process.

[0045] As Figure 8 shown, a tapered hole 26 is provided at the outer end of the ejector rod 10. A blind hole 27 is provided at the bottom of the tapered hole 26. A conductive block 28 which is electrically slidably connected thereto is provided inside the blind hole 27. An avoidance groove 29 is provided on the outer end face of the conductive block 28 corresponding to the insertion pin 12. A fourth return spring 30 is provided between the inner end face of the conductive block 28 and the bottom surface of the blind hole 27. During the working process, when the insertion pin 12 pierces the yoga mat downward, the tip of the insertion pin 12 will insert into the inside of the avoidance groove 29. The avoidance groove 29 can protect the tip of the insertion pin 12, that is, replace the point contact between the insertion pin 12 and the conductive block 28 with a surface contact, so as to avoid damage to the insertion pin 12 due to excessive single-point temperature. At the same time, the fourth return spring 30 can convert the rigid contact between the insertion pin 12 and the ejector rod 10 into an elastic contact, effectively avoiding the damage of the tip of the insertion pin 12 due to impact during the working process. This design further ensures the safety and stability of the insertion pin 12 during the working process. And after the insertion pin 12 and the ejector rod 10 are powered on and heated, the yoga mat will be locally heat-sealed according to the shapes of the insertion pin 12, the ejector rod 10 and the tapered hole 26. Thus, a groove corresponding to the outer side of the ejector rod 10 will be formed on the bottom surface of the yoga mat, and a fine hole corresponding to the outer side of the insertion pin 12 will be formed on the top surface of the yoga mat. A tapered through hole extending downward corresponding to the shape of the tapered hole 26 will be formed between the groove and the fine hole. The downward-extending tapered through hole can enable the sweat or hot air generated by the user during the exercise process to penetrate from the top surface of the yoga mat to the reverse side, rather than allowing the sweat or hot air to penetrate from the reverse side of the yoga mat to the top surface. This design can effectively discharge the sweat and heat generated by the user during the exercise process, further increasing the comfort of the user when using the yoga mat.

[0046] In summary, during the use of the present invention, the yoga mat to be processed is placed on the conveyor 2 at one end of the mounting frame 1. When the conveyor 2 is turned on, the yoga mat to be processed will be conveyed between the first mounting cylinder 6 and the second mounting cylinder 8. Then, when the power device 3 is turned on, after the power device 3 starts, it will drive the first mounting cylinder 6 and the second mounting cylinder 8 to rotate synchronously through the transmission assembly. As the first mounting cylinder 6 rotates, the first mounting cylinder 6 will drive the ejector rod 10 to slide on the outside of the special-shaped camshaft 5. When the ejector rod 10 slides to the thick side of the special-shaped camshaft 5, the ejector rod 10 will extend out of the outside of the first mounting cylinder 6. At the same time, the second mounting cylinder 8 will drive the corresponding needle 12 to rotate to between the air hole 13 and the extended ejector rod 10. At this time, the transmission assembly will drive the air pressure assembly to generate air pressure, and the air pressure will push the needle 12 downward through the air hole 13. The needle 12 will pierce the yoga mat and contact the ejector rod 10. After the ejector rod 10 contacts the needle 12, it will connect to an external power supply and generate heat. After the ejector rod 10 and the needle 12 generate heat, they will perform local thermal shaping on the yoga mat. The local strength of the yoga mat after thermal shaping will increase, and it is beneficial to improve its wear resistance.

[0047] The transmission assembly ingeniously adopts a combination of gear transmission and pneumatic transmission. During the working process, the gear meshing transmission adopted has an accurate and stable transmission ratio, which can effectively ensure the stability and accuracy of the forming process of the yoga mat. At the same time, it cooperates with pneumatic transmission to perform piercing forming on the yoga mat, making the yoga mat have air permeability and water permeability in terms of structure. Moreover, non-toothed parts are correspondingly provided on the outside of the first driving gear 15 and the second driving gear 16. The β angle corresponding to the toothed part of the first driving gear 15 is not greater than the α angle corresponding to the non-toothed part of the second driving gear 16. That is, when the toothed part of the first driving gear 15 meshes with the first driven gear 17, the toothed part of the second driving gear 16 does not mesh with the rack 19. This design can avoid movement interference during the working process of the transmission assembly, ensuring the feasibility and stability of the present invention during the working process.

[0048] During the working process, after the pin 12 pierces down through the yoga mat, the tip of the pin 12 will insert into the inside of the avoidance groove 29. The avoidance groove 29 can protect the tip of the pin 12, that is, replace the point contact between the pin 12 and the conductive block 28 with a surface contact, so as to avoid damage to the pin 12 caused by excessive temperature at a single point. At the same time, the fourth return spring 30 can convert the rigid contact between the pin 12 and the ejector rod 10 into an elastic contact, effectively avoiding damage to the tip of the pin 12 due to impact during the working process. This design further ensures the safety and stability of the pin 12 during the working process. After the pin 12 and the ejector rod 10 are powered on and heated, the yoga mat will be locally heat-shaped according to the shapes of the pin 12, the ejector rod 10, and the tapered hole 26. As a result, a groove corresponding to the outer side of the ejector rod 10 will be formed on the bottom surface of the yoga mat, and fine holes corresponding to the outer side of the pin 12 will be formed on the top surface of the yoga mat. A tapered through hole extending downward corresponding to the shape of the tapered hole 26 will be formed between the groove and the fine holes. The downward-extending tapered through hole enables sweat or hot air generated by the user during exercise to penetrate from the top surface of the yoga mat to the bottom surface, rather than from the bottom surface of the yoga mat to the top surface. This design can effectively discharge the sweat and heat generated by the user during exercise, further increasing the comfort of the user when using the yoga mat.

[0049] In summary, the overall structure of the present invention is simple and ingenious. Through the combination of gear clearance transmission, pneumatic transmission, and electrothermal principle, local heat shaping can be performed on the yoga mat during the production and manufacturing process of the yoga mat, enabling the yoga mat to have the functions of air permeability and sweat discharge. The yoga mat processed and formed by the present invention is very suitable for people who practice yoga or do indoor fitness. The present invention has positive application and promotion value.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
