Description

Technical Field

[0001] This invention relates to the field of yoga mat processing technology, specifically to a sandwich rubber yoga mat and its manufacturing method. Background Technology

[0002] A yoga mat is the mat you lay on when practicing yoga. Currently, yoga mats are divided into traditional yoga mats and alignment yoga mats: traditional yoga mats are mats without lines; alignment yoga mats are mats with lines, offering the general functions of traditional yoga mats while also guiding the practice of more scientific and precise yoga postures. Yoga mats are generally made of materials such as rubber foam, TPE foam, PVC foam, EVA, latex, and CBR. During the manufacturing process, the side of the yoga mat facing the body is usually sprayed or printed with decorative elements to display the manufacturer's logo or enhance its aesthetics.

[0003] According to Chinese Patent Application No. CN201911146712.3, a method for manufacturing a PVC yoga mat surface decoration includes a base plate, an operation box above the base plate, two connecting plates symmetrically fixed between the operation box and the base plate, a support mechanism fixed between the base plate and the operation box, a walking mechanism at the lower end of the base plate, and a limiting mechanism corresponding to the walking mechanism at the lower end of the base plate. One of the connecting plates is fixed with a synchronous detection device and a cooling system, and the other connecting plate is fixed with a cylindrical surface printing screen and a gravure printing position. This method for manufacturing a PVC yoga mat surface decoration adds automatic synchronous roller printing to the PVC yoga mat production line. The high degree of automation reduces subsequent manual labor and solvent contamination issues. The printing materials used can be well integrated with the PVC yoga mat, and foam printing can be achieved, increasing the product's appearance. The three-dimensional printed foamed parts can increase the product's anti-slip properties.

[0004] In the above technical solution, when printing decorations on the surface of a yoga mat, the yoga mat is pulled to one side of a "cylindrical screen printing plate" by multiple rollers, and the yoga mat is printed on by the plate. Since the yoga mat is made of rubber foam, it has a certain degree of elasticity. When the yoga mat is pulled a long distance, it will stretch itself. After the yoga mat rebounds, the surface decoration printed on it will fold due to the rebound, resulting in problems such as missing parts of the surface decoration or unclear patterns. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sandwich rubber yoga mat and its manufacturing method, which solves the problem that in existing printing equipment, when the yoga mat is stretched over a long distance, the printed surface decoration will fold after the yoga mat rebounds, resulting in missing parts of the surface decoration or unclear patterns.

[0037] In summary, the present invention has the following main beneficial effects:

[0038] By setting up brackets, during use, the operator can place the roller containing the yoga mat on two brackets. One end of the yoga mat is held by the elastic clamping part and the clamping component on the slide rod. Specifically, the operator can use the first moving part to move the printing device downwards. When the printing device moves downwards, the second moving part can move the slide rod. The clamping component on the slide rod uses the upper and lower clamping rods to hold the yoga mat. When the slide rod moves away from the elastic clamping part, it can pull the yoga mat, allowing the yoga mat to be placed on top of the tray. When the slide rod moves to a preset position, the clamping component can move the upper and lower clamping rods to relax the yoga mat. The yoga mat is released onto the top of the tray, and the top rods protrude from the tray. Multiple top rods support the yoga mat, creating a certain gap between the yoga mat and the tray. Furthermore, the yoga mat itself has a certain degree of elasticity; when the yoga mat is released after being pulled, it will spring back. The yoga mat has an anti-slip pad on the bottom to prevent it from slipping on the ground. Therefore, the yoga mat needs to be raised to prevent the anti-slip pad from contacting the support plate, which would prevent the mat from rebounding. The printing device continues to move downwards, and the position of the top rod and the sealing plate can be moved by the third moving part, allowing the top rod to move away from the top opening and the sealing plate to close the top opening. This avoids the printing device squeezing the yoga mat due to the gap formed by the top opening, causing the yoga mat part to be embedded in the top opening and resulting in a depression above it, leading to poor printing results. After printing, the operator can use a cutting tool or other cutting mechanism to cut and remove the yoga mat, completing the printing work. This solves the problem in existing technologies where, after the yoga mat rebounds, the surface decoration printed on the stretched yoga mat will fold due to the rebound, resulting in missing parts of the surface decoration or unclear patterns.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] refer to Figures 1-13 A method for manufacturing a laminated rubber yoga mat includes the following steps:

[0063] Step 1: Mix the ingredients according to the preset proportions to form a mixture, which includes polyvinyl chloride, plasticizer, foaming agent, color paste, calcium carbonate and nitrile rubber;

[0064] Step 2: Use a mixing mechanism to mix the ingredients;

[0065] Step 3: Apply the mixture using a coating machine to form a strip base band 801;

[0066] Step 4: Perform foaming operation on strip base tape 801;

[0067] Step 5: Apply glue to the two strip base strips 801, place a moisture-absorbing pad 802 between the two strip base strips 801, and use glue to bond the three together to form a yoga mat 800.

[0068] Step Six: Sew a non-slip rubber pad 803 onto the bottom of the yoga mat 800;

[0069] Step 7: Use a winding roller to wind up the yoga mat (800mm).

[0070] Step 8: Print the yoga mat 800 using a printing machine;

[0071] The printing institutions include:

[0072] The base plate 100 and the top frame 101 are connected by multiple support rods 102;

[0073] The printing device 103 is located at the bottom of the top frame 101;

[0074] The base 104 is located on the top of the base plate 100. The top of the base 104 has a groove 105. A support plate 106 is fixedly fitted inside the groove 105. The top of the support plate 106 has multiple top openings 107.

[0075] Two brackets 108 are respectively connected to two support rods 102;

[0076] The elastic clamping part 109 is located on the top of the base 104 and is used to position one end of the yoga mat 800.

[0077] A slide bar 110 is located on the top of the base 104. The top and bottom of the slide bar 110 are respectively provided with multiple upper clamping rods 111 and lower clamping rods 112.

[0078] Multiple sealing plates 113 are provided in the groove 105. The sealing plates 113 are adapted to the top opening 107. Top rods 114 are provided on both sides of the sealing plates 113. The top rods 114 protrude from the support plate 106 through the top opening 107. Rollers 115 are rotatably connected to the top of the top rods 114.

[0079] The first movable component is located between the top frame 101 and the printing device 103, and is used to move the position of the printing device 103 up and down.

[0080] The second moving part is located between the printing device 103 and the slide bar 110. It is used to move the slide bar 110 away from the elastic clamping part 109 when the printing device 103 moves downward and to move the slide bar 110 closer to the elastic clamping part 109 when the printing device 103 returns to its original position.

[0081] A clamping component is provided on the slide bar 110, which is used to clamp the yoga mat 800 with the upper clamping bar 111 and the lower clamping bar 112 when the slide bar 110 moves toward the elastic clamping part 109 to a preset position, and to release the yoga mat 800 with the upper clamping bar 111 and the lower clamping bar 112 when the slide bar 110 moves away from the elastic clamping part 109 to a preset position.

[0082] The third moving component is located between the printing device 103 and the base 104, and is used to move the top rod 114 downward and the sealing plate 113 upward when the printing device 103 moves downward to the preset position.

[0083] By setting up brackets 108, during use, the operator can place the roller containing the yoga mat 800 on the two brackets 108. One end of the yoga mat 800 is held by the elastic clamping part 109 and the clamping component on the slide bar 110. Specifically, the operator can use the first moving part to move the printing device 103 downward. When the printing device 103 moves downward, the second moving part can move the slide bar 110. The clamping component on the slide bar 110 uses the upper clamping rod 111 and the lower clamping rod 112 to clamp the yoga mat 800. When the elastic clamping part 109 moves away from the yoga mat 800, it can pull the yoga mat 800, allowing it to lie on top of the support plate 106. The clamping components can move the upper clamping rod 111 and the lower clamping rod 112 when the slide rod 110 moves to a preset position, loosening the yoga mat 800. The yoga mat 800 is released onto the top of the support plate 106. The top rod 114 protrudes from the support plate 106, and multiple top rods 114 support the yoga mat 800, creating a certain gap between the yoga mat 800 and the support plate 106. Furthermore, the yoga mat 800 itself has a certain degree of elasticity, allowing it to be released after being pulled. When the yoga mat 800 is in use, it will rebound. The bottom of the yoga mat 800 is equipped with an anti-slip rubber pad 803 to prevent slipping on the ground. Therefore, the yoga mat 800 needs to be raised to prevent the anti-slip pad on the bottom of the yoga mat 800 from contacting the support plate 106, which would prevent the yoga mat 800 from rebounding. The printing device 103 continues to move downwards, and the third moving component can move the position of the top rod 114 and the sealing plate 113, allowing the top rod 114 to move away from the top opening 107 and the sealing plate 113 to close the top opening 107. This prevents the printing device 103 from printing on the yoga mat 800 due to the top opening... The notch formed by the opening 107 causes the printing device 103 to squeeze the yoga mat 800, and part of the yoga mat 800 is embedded in the top opening 107, resulting in a depression above it and causing poor printing effect. After printing is completed, the operator can use a cutting tool or other cutting mechanism to cut and remove the yoga mat 800, thus completing the printing work on the yoga mat 800. This solves the problem in the prior art that when the surface decoration printed on the stretched yoga mat 800 is folded due to the rebound of the yoga mat 800, the surface decoration will be missing or the pattern will be unclear.

[0084] As a further embodiment of the present invention, the third moving component includes a limiting rod 200 connected to the bottom of the groove 105, a top rod 114 slidably connected to the limiting rod 200, a first spring 201 connected between the groove 105 and the top rod 114, a connecting rod 202 connected between every two top rods 114, a bracket 203 connected to the bottom of the groove 105, a first shaft 204 and a second shaft 205 rotatably connected to the bracket 203, a first rope 206 connected between the first shaft 204 and the connecting rod 202, a second rope 207 wound on the second shaft 205, a sliding groove 208 opened at the bottom of the sealing plate 113, a traction rod 209 slidably sleeved in the sliding groove 208, a second spring 210 connected between the traction rod 209 and the sliding groove 208, one end of the second rope 207 connected to the traction rod 209, and a first gear 211 and a second gear 212 meshing with each other connected to the first shaft 204 and the second shaft 205 respectively.

[0085] By setting a second gear 212, the diameter of which is larger than that of the first gear 211, and the tension of the second spring 210 being greater than that of the first spring 201, when the sealing plate 113 moves upward, the second spring 210 and the traction rod 209 can be used to pull the second rope 207. The second rope 207 forces the second shaft 205 to rotate. The rotation of the second shaft 205 can cause the first shaft 204 to rotate through the second gear 212 and the first gear 211. The rotation speed of the first shaft 204 is greater than that of the second shaft 205. The rotation of the first shaft 204 can wind up the first rope 206, causing the top rod 114 to move downward. This achieves the purpose of causing the top rod 114 to move downward when the sealing plate 113 moves up and down. The purpose of causing the top rod 114 to move downward quickly when the sealing plate 113 moves upward is to avoid the top rod 114 blocking the upward movement of the sealing plate 113.

[0086] As a further embodiment of the present invention, the third moving component also includes a first rack 213 connected to the top of the printing device 103, and side openings 214 communicating with the groove 105 are respectively provided on both sides of the base 104. A horizontal plate 215 connected to the sealing plate 113 is slidably connected in the side openings 214. A second rack 216 is connected to the top of the horizontal plate 215, and a third gear 217 meshing with the second rack 216 is respectively connected to both sides of the base 104.

[0087] By setting the first rack 213, when the printing device 103 moves downward to the preset position, the first rack 213 can mesh with the third gear 217. When the printing device 103 continues to move downward, the second rack 216 can be moved upward through the third gear 217, thereby achieving the purpose of moving the sealing plate 113 upward.

[0088] As a further embodiment of the present invention, the clamping component includes a sliding cavity 300 formed at the top of the slide rod 110, the sliding cavity 300 passing through the slide rod 110, and third racks 301 respectively connected to the two sides of the upper clamping rod 111 and the lower clamping rod 112 that are close to each other. A fourth gear 302 that meshes with the third racks 301 is rotatably connected inside the sliding cavity 300, and third springs 303 are respectively connected between the two third racks 301 and the sliding cavity 300.

[0089] By setting a third spring 303, the upper clamping rod 111 or the lower clamping rod 112 can be moved during use. When one of the upper clamping rod 111 or the lower clamping rod 112 moves, the other clamping rod can be moved by the third rack 301 and the fourth gear 302. When the yoga mat 800 is between the upper clamping rod 111 and the lower clamping rod 112, the force of the third spring 303 can be used to reset the upper clamping rod 111 and the lower clamping rod 112 to achieve clamping of the yoga mat 800.

[0090] As a further embodiment of the present invention, the clamping component also includes a frame 304 connected to one side of the elastic clamping part 109. The bottom of the frame 304 is connected to a support rod 305 connected to the elastic clamping part 109. The top of the frame 304 is provided with a through hole 306. A stop rod 307 is provided in the through hole 306. Two support plates 308 are connected to one side of the through hole 306. A connecting shaft 309 rotatably sleeved with the stop rod 307 is fixedly connected between the two support plates 308. A spring 310 is connected between the connecting shaft 309 and the stop rod 307. The top of the lower clamping rod 112 is at the same height as the top of the stop rod 307. A push rod 311 is connected to the top of the base 104. A push block 312 is connected to the top of the upper clamping rod 111.

[0091] By setting the stop bar 307, the specific shape of the stop bar 307 and the through-hole 306 can restrict the rotation direction of the stop bar 307, preventing it from rotating towards the elastic clamping part 109 through the through-hole 306. The upper clamping rod 111 and the lower clamping rod 112 are sloped towards the end facing the yoga mat 800. When the slide rod 110 moves the upper clamping rod 111 and the lower clamping rod 112 towards the frame 304, the lower clamping rod 112 contacts the stop bar 307 and is restricted by the stop bar 307. When the slide rod 110 continues to move, the lower clamping rod 112 will generate a downward force and synchronously move the upper clamping rod 111 using the fourth gear 302, increasing the distance between them so that the upper clamping rod 111 and the lower clamping rod 112 can be at the top and bottom of the yoga mat 800. The upper clamping rod 111 and the lower clamping rod 112 move out of the frame 304. When the stop bar 307 is engaged, the force of the third spring 303 can be used to reset the upper clamping bar 111 and the lower clamping bar 112, thereby achieving the clamping of the yoga mat 800. When the slide bar 110 is reset, the lower clamping bar 112 can touch the stop bar 307, allowing the stop bar 307 to rotate clockwise around the connecting shaft 309, which can open the through hole 306, allowing the lower clamping bar 112 to leave the frame 304. This allows the upper clamping bar 111 and the lower clamping bar 112 to clamp the yoga mat 800 and move the yoga mat 800 onto the top of the support plate 106 when the slide bar 110 moves to the preset position. When the slide bar 110 is reset, the push block 312 can contact the push rod 311 and, restricted by the push rod 311, move the upper clamping bar 111 upward, thereby achieving the purpose of relaxing the yoga mat 800 when the slide bar 110 is reset to the preset position.

[0092] As a further embodiment of the present invention, the second moving component includes a connection port 400 opened at the top of the top frame 101, a first sprocket 401 rotatably connected in the connection port 400, support rods 402 respectively connected to both sides of the base 104, a first lead screw 403 rotatably connected to the support rods 402, a slide rod 110 threadedly connected to the first lead screw 403, a fifth gear 404 respectively connected to both ends of the first lead screw 403, a sixth gear 405 rotatably connected to one side of the support rod 402 and meshing with the fifth gear 404, a second sprocket 406 connected to one side of the sixth gear 405, a chain 407 connected between the second sprocket 406 and the first sprocket 401, and a connecting rod 408 connected to the chain 407 connected to the top of the printing device 103;

[0093] By setting a connecting rod 408, when the printing device 103 moves downward, the connecting rod 408 can be moved. The connecting rod 408 pulls the chain 407, which can drive the second sprocket 406 and the sixth gear 405 to rotate. The rotation of the sixth gear 405 can drive the fifth gear 404 and the first lead screw 403 to rotate. The rotation of the first lead screw 403 can move the slide bar 110. In this way, the purpose of moving the slide bar 110 laterally through the first lead screw 403 can be achieved when the printing device 103 moves vertically.

[0094] As a further embodiment of the present invention, the first moving component includes two sliding rods 500 slidably connected to the top frame 101, and two connecting shafts 501 rotatably connected to the printing device 103 respectively on the two sliding rods 500. A second lead screw 502 threadedly connected to the sliding rods 500 is rotatably connected to one side of the top frame 101. A motor 503 is provided on one side of the top frame 101. The drive shaft of the motor 503 and the second lead screw 502 are respectively connected to a seventh gear 504 that meshes with each other.

[0095] By setting up a motor 503, the motor 503 can rotate the second lead screw 502 through two seventh gears 504. The rotation of the second lead screw 502 can move the two sliding rods 500 closer to each other, and through the coupling shaft 501, the printing device 103 can be moved downward, thereby achieving the purpose of making the printing device 103 move vertically.

[0096] As a further embodiment of the present invention, the elastic clamping part 109 includes a first plate 600 connected to the top of the base 104, a frame 304 and a support rod 305 connected to one side of the first plate 600, a second plate 601 provided on the top of the first plate 600, a fourth spring 602 connected between the first plate 600 and the second plate 601, and rollers 603 rotatably connected to the two sides of the first plate 600 and the second plate 601 that are close to each other.

[0097] By setting the first plate 600, during use, one end of the yoga mat 800 can be pulled between the first plate 600 and the second plate 601 and extended to the top of the top frame 101, supported by the top frame 101 and the stop bar 307. The fourth spring 602 applies a clamping force to the second plate 601 to hold the yoga mat 800. When the upper and lower clamps move the yoga mat 800, the roller 603 can rotate, allowing the yoga mat 800 to move horizontally between the first plate 600 and the second plate 601.

[0098] As a further embodiment of the present invention, a connecting groove 700 is provided on the top of the base 104, a first hydraulic cylinder 701 is provided in the connecting groove 700, a connecting plate 702 is connected to the top of the first hydraulic cylinder 701, a plurality of supporting plates 703 are connected to the top of the connecting plate 702, the spacing between the supporting plates 703 and the frame 304 and the supporting rod 305 is adapted, a connecting frame 704 is connected to the bottom of the top frame 101, a second hydraulic cylinder 705 is connected to the bottom of the connecting frame 704, and a cutting blade 706 is connected to the bottom of the second hydraulic cylinder 705.

[0099] By setting the cutting blade 706, during the process of the printing device 103 gradually resetting upward after printing is completed, the operator can start the first hydraulic cylinder 701 and the second hydraulic cylinder 705. The first hydraulic cylinder 701 moves the receiving plate 703 upward, so that the receiving plate 703 is fitted into the frame 304 and flush with the stop bar 307. The second hydraulic cylinder 705 moves the cutting blade 706 downward to cut the yoga mat 800 between the receiving plate 703 and the cutting blade 706. After cutting, the operator or robot can take out the formed yoga mat 800.

[0100] Furthermore, such as Figure 6 As shown, the slide bar 110 has a certain distance from the base 104, which is greater than the thickness of the yoga mat 800. That is, after the upper and lower clamps on the slide bar 110 loosen the yoga mat 800, the extended yoga mat 800 rebounds, and one end of the yoga mat 800 can leave the upper clamp bar 111 and the lower clamp bar 112 and fall onto the top bar 114. When the printing device 103 resets after printing is completed, the top bar 114 can lift the yoga mat 800 again, so that there is a certain gap between the yoga mat 800 and the tray 106. This avoids the problem of difficulty in picking up the yoga mat 800 due to the friction between the anti-slip rubber pad 803 on the bottom and the tray 106 when the yoga mat 800 is taken out. At the same time, when the cutting blade 706 has not yet cut the yoga mat 800 during the upward reset of the printing device 103, the yoga mat 800 on the top of the tray 106 will not affect the movement of the slide bar 110 toward the frame 304.

[0101] A sandwich rubber yoga mat includes two strip-shaped base strips 801, with a moisture-absorbing pad 802 pasted between the two strip-shaped base strips 801, and multiple anti-slip pads 803 sewn to the bottom of the bottom strip-shaped base strip 801.

[0102] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
