Description

Technical Field

[0001] The utility model relates to the field of processing equipment, in particular to a sheet-like tensioning component welding device. Background Art

[0002] Inflatable products are common recreational or functional products with a certain shape on the market. Due to their portability and flexibility, they have different applications in various fields. Most inflatable products, such as inflatable pools, inflatable mattresses, inflatable camping mats, etc., are equipped with tensioning components in the gas chamber inside them in order to maintain a stable shape after inflation.

[0003] refer to Figure 1a The side wall of the inflatable product 10 includes a first wall 11 and a second wall 12, which are connected by a sheet-like tensioning member 21, and an inflatable chamber 13 is formed between the first wall 11 and the second wall 12. The inflatable chamber 13 is inflated to form a shaped and stable inflatable product 10. In the production process of the side wall of the inflatable product 10, the second sheet material 23 needs to be processed and cut into the sheet-like tensioning member 21, and then the sheet-like tensioning member 21 is welded to the first wall 11 and the second wall 12.

[0004] In the current production process of the inflatable product 10, the processing of the first wall 11, the second wall 12 and the tension member 21 of the inflatable product 10 is usually carried out separately, wherein the processing of the first wall 11 and the second wall 12 is similar, usually including printing and drying, and sometimes it is necessary to process air holes for air flow in and out, etc., and cut into pieces of the required size after the necessary processing. The tension member 21 is cut according to the required shape, and then the cut tension member 21 is stacked together with the pieces of the first wall 11 and the second wall 12 on a welding device for welding to form an inflatable semi-finished product, and the inflatable semi-finished product is then closed and welded to form a closed inflatable chamber 13. The above-mentioned method of producing inflatable semi-finished products is inefficient, which indirectly leads to low production efficiency and poor economic benefits of the inflatable product 10.

[0121] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0122] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0123] refer to Figure 1a to Figure 1b In the description of the present application, the inflatable product 10 includes at least one first wall 11, a second wall 12 and an inflatable chamber 13 for inflation defined by the first wall 11 and the second wall 12. After the pressure of the gas (e.g., air) in the inflatable chamber 13 reaches a desired value, the inflatable product 10 is in an inflated state and maintains a preset shape; and when the gas in the inflatable chamber 13 is discharged, the inflatable product 10 is in a deflated state, and the volume of the inflatable product 10 is greatly reduced relative to when it is in the inflated state, thereby facilitating the storage of the inflatable product 10.

[0124] A plurality of tensioning members are provided in the inflation chamber 13 of the inflatable product 10, and the tensioning members are connected to the first wall 11 and the second wall 12 by high-frequency welding, hot melting, gluing or other connection methods. After being tensioned, the tensioning members provide a pulling force to the first wall 11 and the second wall 12 to limit the deformation of the inflatable product 10, so that the inflatable product 10 can maintain a preset shape after being inflated. Optionally, the plurality of tensioning members have different structures in different embodiments. For example, each tensioning member is a sheet-like tensioning member 21. The sheet-like tensioning member 21 can have a single-layer or composite-layer structure according to actual needs.

[0125] When the sheet-like tension member 21 is a single-layer sheet, it can be made of a polymer material, which can include but is not limited to one or more of polyvinylchloride (PVC), polyurethane (PU), thermoplastic urethanes (TPU), polyethyleneterephthalate (PET), ethylene-vinylacetate (EVA) copolymer and nylon. It can be understood that the main body of the single-layer sheet-like tension member 21 can also be made of other materials other than polymer materials in other embodiments, such as a fabric material, wherein the fabric material can be finely woven or formed into a mesh structure. The fabric material can be but is not limited to a natural fiber fabric (for example, but not limited to, cotton fabric, linen fabric, wool fabric, silk fabric) or a synthetic fiber fabric (for example, but not limited to, polyester fiber fabric, polyethylene fiber fabric, polypropylene fiber fabric).

[0126] When the sheet-like tension member 21 is a composite sheet, it is composed of two or more layers of sheets bonded together by gluing, welding or other means, and each layer of the multi-layer sheet can be made of the polymer material or other materials as described above.

[0127] During the use of the inflatable product 10, the sheet tensioning member 21 forms a tensioning force on the first wall 11 and the second wall 12, and the sheet tensioning member 21 itself is in a state of relatively large tensile stress; the connection between the sheet tensioning member 21 and the first wall 11 or the second wall 12 generates a stress that tends to separate, and the stress is particularly evident at the connection between the ends of the sheet tensioning member 21; when the sheet tensioning member 21 separates from the first wall 11 or the second wall 12, it often starts to separate from both ends of the sheet tensioning member 21, eventually causing the inflatable product 10 to be deformed and damaged. Therefore, notches 25 are provided at both ends of the sheet tensioning member 21 to reduce the stress at both ends of the sheet tensioning member 21 and reduce the risk of separation at the connection between the sheet tensioning member 21 and the first wall 11 or the second wall 12.

[0128] The embodiment of the present application provides a sheet-like tension member welding device, which is used to process the first sheet material 14, the second sheet material 23 and the third sheet material 15. Specifically, the sheet-like tension member welding device of the embodiment of the present application is used to cut the second sheet material 23 to form the sheet-like tension member 21, then weld the sheet-like tension member 21 to the first sheet material 14 and the third sheet material 15 at the same time to form a double-layer sheet material 30, and finally cut the double-layer sheet material 30 to form an inflatable semi-finished product (i.e., a semi-finished product of the inflatable product 10). The first sheet material 14 eventually becomes the first wall 11 of the inflatable product 10, and the third sheet material 15 eventually becomes the second wall 12 of the inflatable product 10.

[0129] refer to Figure 2 Combined with Figure 1b to Figure 1d The sheet tensioning member welding device provided in the embodiment of the present application includes: a loading station 100, a cutting station 200, a welding station 300, a conveying station 400, a tensioning mechanism 500, a detection mechanism 600 and a receiving station 700 arranged in sequence along a first direction X.

[0130] The loading station 100 is used to provide the second sheet material 23 to the cutting station, and to provide the first sheet material 14 and the third sheet material 15 to the welding station 300 .

[0131] At the cutting station 200, the second sheet material 23 is first trimmed along both sides of the second direction Y to form an arc-shaped notch 25, and then the trimmed second sheet material 23 is cut along the second direction Y to form a Figure 1c The sheet-like tensioning members 21 shown in the figure, that is, each sheet-like tensioning member 21 has a notch 25 on both sides along the second direction Y. Further, the cutting station 200 transfers the cut sheet-like tensioning members 21 to the welding station 300, so that the sheet-like tensioning members 21 are welded to the first sheet material 14 and the third sheet material 15 to form a double-layer sheet material 30 (such as Figure 1d shown).

[0132] The conveying station 400 is used to convey the welded double-layer sheet 30 to the tensioning mechanism 500. The tensioning mechanism 500 is used to tension the double-layer sheet 30 for easy collection. The detection mechanism 600 is used to detect the double-layer sheet 30 before collection, for example, to detect whether the double-layer sheet 30 has a weld seam to ensure that the double-layer sheet 30 to be collected has been welded by the welding station 300.

[0133] The receiving station 700 is used to cut the double-layer sheet 30 to form an inflatable semi-finished product and to receive the inflatable semi-finished product. The inflatable semi-finished product can be used to be closed and welded with other sheets to form a closed inflatable chamber 13. The first sheet 14 eventually becomes the first wall 11 of the inflatable product 10, and the third sheet 15 eventually becomes the second wall 12 of the inflatable product 10.

[0134] It should be noted that along the first direction X, the direction from the loading station 100 to the receiving station 700 is the feeding direction X1. In the embodiment of the present application, the feeding direction X1 is a straight line, but is not limited to this. In other possible implementations, the feeding direction X1 can also be a curve, which can be adjusted according to the internal space of the factory.

[0135] The embodiment of the present application does not impose any specific limitation on the order of the cutting station 200 , welding station 300 , conveying station 400 , tensioning mechanism 500 and detection mechanism 600 , which can be adjusted according to actual needs.

[0136] The specific structure of the loading station 100 is described in detail below with reference to the accompanying drawings.

[0137] refer to Figures 3 to 5 Combined with Figure 2 The loading station 100 includes a first loading assembly 110, a second loading assembly 120 and a third loading assembly 130. The first loading assembly 110 is used to provide the first sheet material 14, the second loading assembly 120 is used to provide the second sheet material 23, and the third loading assembly 130 is used to provide the third sheet material 15.

[0138] Specifically, the first feeding assembly 110 includes: a first feeding bracket 111, a first feeding roller 112, a first material transfer roller 140 and a first movable roller 150. The first feeding bracket 111 is a substantially rectangular frame. The first feeding roller 112 extends along the second direction Y and is rotatably connected to the first feeding bracket 111. The first feeding roller 112 is used to install the first sheet material roll 16. The first sheet material 14 on the first sheet material roll 16 is sequentially wound around the first movable roller 150 and the first material transfer roller 140, and is transferred to the welding station 300 through the first intermediate material transfer roller 216 located above the cutting station 200.

[0139] The second feeding assembly 120 includes: a second feeding bracket 121, a second feeding roller 122, a first material transfer roller 140 and a first movable roller 150. The second feeding bracket 121 is a substantially rectangular frame. The second feeding roller 122 extends along the second direction Y and is rotatably connected to the second feeding bracket 121. The second feeding roller 122 is used to install the second sheet material roll 24. The second sheet material 23 on the second sheet material roll 24 is sequentially wound around the first movable roller 150 and the first material transfer roller 140 and transmitted to the cutting station 200.

[0140] The third feeding assembly 130 includes: a third feeding bracket 131, a third feeding roller 132, a first feeding roller 140 and a first movable roller 150. The third feeding bracket 131 is a substantially stepped frame. The third feeding roller 132 extends along the second direction Y and is rotatably connected to the third feeding bracket 131. The third feeding roller 132 is used to mount the third sheet material roll 17. The third sheet material 15 on the third sheet material roll 17 is sequentially wound around the first movable roller 150 and the first feeding roller 140, and is transferred to the welding station 300 through the second intermediate feeding roller 217 and the third intermediate feeding roller 218 located below the cutting station 200.

[0141] The relationship among the first loading roller 112 , the first transfer roller 140 and the first movable roller 150 will be described below by taking the first loading assembly 110 as an example.

[0142] For example, reference Figure 5 Combined with Figure 3 , first movable roller guide rails 152 are respectively provided on both sides of the first feeding bracket 111 along the second direction Y, each first movable roller guide rail 152 extends along the third direction Z, and a first movable roller slider 151 is respectively provided at both ends of the first feeding roller 112 along the second direction Y, and each first movable roller slider 151 is connected to a first movable roller guide rail 152 in a movable manner along the third direction Z. In addition, the first feeding roller 112, the first movable roller 150 and the first transfer roller 140 are distributed in a triangle (such as Figure 3 shown).

[0143] Furthermore, during the loading process, the first sheet 14 of the first sheet roll 16 is sequentially wound around the first movable roller 150 and the first transfer roller 140. The first movable roller 150 presses the first sheet 14 down along the third direction Z due to its own gravity, so that the first sheet 14 is tensioned, which is beneficial to the subsequent welding of the first sheet 14.

[0144] The positional relationship between the second loading bracket 121, the second loading roller 122, the first transfer roller 140 and the first movable roller 150 in the second loading component 120, and the positional relationship between the third loading bracket 131, the third loading roller 132, the first transfer roller 140 and the first movable roller 150 in the third loading component 130 are the same as the first loading bracket 111, the first loading roller 112, the first transfer roller 140 and the first movable roller 150 in the first loading component, and will not be repeated here.

[0145] Exemplarily, one end of the first feeding roller 112 along the second direction Y is connected to a magnetic powder tensioner 170, one end of the second feeding roller 122 along the second direction Y is connected to a magnetic powder tensioner 170, and one end of the third feeding roller 132 along the second direction Y is connected to a magnetic powder tensioner 170. Taking the first feeding roller 112 as an example, the magnetic powder tensioner 170 can provide a braking force, thereby controlling the rotation amplitude of the first feeding roller 112, and can effectively adjust the feeding amount of the first sheet 14. In other words, the feeding amounts of the first sheet 14, the second sheet 23, and the third sheet 15 can be controlled by three magnetic powder tensioners 170.

[0146] For example, reference Figure 4 Combined with Figure 2 and Figure 3 , two stop plates 180 are provided on each of the first feeding roller 112, the second feeding roller 122 and the third feeding roller 132, and the two stop plates 180 are spaced apart along the second direction Y (the second direction Y is perpendicular to the first direction X). The function of the stop plates 180 is to effectively prevent the sheet roll from deviating along the second direction Y during the feeding process. Taking the first feeding roller 112 as an example, the first sheet roll 16 is installed on the first feeding roller 112, and abuts against the two stop plates 180 on the first feeding roller 112 along the second direction Y. When the first sheet roll 16 has a tendency to deviate along the second direction Y, the stop plates 180 can abut against the first sheet roll 16 to prevent the first sheet roll 16 from deviating.

[0147] Furthermore, the first loading assembly 110 and the second loading assembly 120 are respectively provided with a correcting mechanism 160 at the bottom along the third direction Z (i.e., the vertical direction, the third direction Z is perpendicular to the first direction X and the second direction Y). The correcting mechanism 160 is used to adjust the positions of the first loading assembly 110 and the second loading assembly 120 along the second direction Y to prevent the first sheet material roll 16 and the second sheet material roll 24 from shifting along the second direction Y, thereby affecting the subsequent processing of the cutting station 200 and the welding station 300.

[0148] Next, the specific structure of the deviation correcting mechanism 160 is explained by taking the first loading assembly 110 as an example.

[0149] For example, reference Figure 5 Combined with Figure 4, a support frame 113 is provided at the bottom of the first feeding bracket 111 along the third direction Z, and the first feeding bracket 111 is connected to the support frame 113 in a manner that it can move along the second direction Y. Specifically, a correction slider 161 is provided at the bottom of the first feeding bracket 111, and correction rails 162 are provided on the top of the support frame 113 on both sides along the first direction X, respectively, and each correction rail 162 extends along the second direction Y. The correction slider 161 is connected to the correction rail 162 in a manner that it can move along the second direction Y. A correction driver 163 is provided on the support frame 113, and the correction driver 163 is connected to the first feeding bracket 111. The correction driver 163 is used to drive the first feeding bracket 111 and the first feeding roller 112 to move relative to the support frame 113 along the second direction Y, so as to adjust the position of the first feeding roller 112 along the second direction Y to achieve correction.

[0150] The embodiment of the present application does not impose any specific limitation on the specific type of the deviation correction driver 163 . For example, the deviation correction driver 163 may be a driver such as a motor or a cylinder.

[0151] The structure of the deflection correction mechanism 160 at the bottom of the second feeding assembly 120 is the same as that of the deflection correction mechanism 160 at the bottom of the first feeding assembly 110. The difference is that the bottom of the second feeding assembly 120 is not provided with a support frame, but is arranged on the top of the third feeding bracket 131. In other words, the deflection correction slide rail 162 and the deflection correction driver 163 of the deflection correction mechanism 160 at the bottom of the second feeding assembly 120 are arranged on the top of the third feeding bracket 131. This arrangement can effectively reduce the space occupied by the sheet-like tension member welding equipment and save site costs.

[0152] The specific structure of the cutting station 200 is described in detail below with reference to the accompanying drawings.

[0153] The cutting station 200 is used to receive the second sheet material 23 from the second feeding roller 122 , and perform trimming and cutting on the second sheet material 23 to form a sheet-like tensioning member 21 .

[0154] Specifically, refer to Figure 6 Combined with Figure 2 and Figure 3 The cutting station 200 includes: a cutting bracket 210, a trimming mechanism 220, a cutting clamping assembly 230, a cutting mechanism 240, a folding device 250, a transfer device 260 and a cutting feed roller group 270.

[0155] Exemplarily, the cutting bracket 210 is a substantially rectangular frame. A support plate 219 is provided above the cutting bracket 210, and the support plate 219 is used to support the first intermediate material transfer roller 216, and the first intermediate material transfer roller 216 extends along the second direction Y. Correspondingly, ladders 211 are provided on both sides of the cutting bracket 210 along the second direction Y, and the ladders 211 are used for workers to climb, so as to wrap the first sheet 14 around the first intermediate material transfer roller 216.

[0156] Furthermore, the above-mentioned second intermediate transfer roller 217 and third intermediate transfer roller 218 are provided below the cutting bracket 210, and the second intermediate transfer roller 217 and the third intermediate transfer roller 218 both extend along the second direction Y, and the second intermediate transfer roller 217 and the third intermediate transfer roller 218 are spaced apart along the first direction X.

[0157] Exemplarily, the cutting bracket 210 has a bottom roller 212 along the third direction Z, and the roller 212 is used to connect to the bracket guide rail 213 on the ground, so that the cutting bracket 210 can move relative to the bracket guide rail 213 along the first direction X, so as to adjust the position of the cutting bracket 210 along the first direction X.

[0158] In the present application examples, reference Figure 3 The above-mentioned support frame 113 is fixed to the cutting bracket 210, but is not limited thereto. In other possible implementations, the support frame 113 may be an independent frame.

[0160] refer to Figure 7 Combined with Figure 6 A trimming movable guide rail 215 is provided on the cutting fixed guide rail 214, and the trimming movable guide rail 215 extends along the second direction Y, and the trimming movable guide rail 215 is connected to the two cutting fixed guide rails 214 in a movable manner along the first direction X, so as to adjust the position of the trimming movable guide rail 215 in the first direction X according to processing needs.

[0161] Exemplarily, two trimming mechanisms 220 are provided on the trimming moving guide rail 215, and the trimming mechanisms 220 are used to trim the second sheet material 23 on both sides along the second direction Y to form a Figure 1cThe two trimming mechanisms 220 are arranged at intervals along the second direction Y, and each trimming mechanism 220 is connected to the trimming movable guide rail 215 in a movable manner along the second direction Y, so as to adjust the distance between the two trimming mechanisms 220 according to processing requirements. For example, when the second sheet material 23 is longer in the second direction Y, the two trimming mechanisms 220 can be moved away from each other in the second direction Y to meet the processing requirements of the second sheet material 23.

[0162] refer to Figure 8 Combined with Figure 1b and Figure 7 The trimming mechanism 220 includes a trimming mechanism body 221, a trimming tool 222, a tool driving unit 223 and a tool fixing plate 225. Exemplarily, the trimming mechanism body 221 has a trimming space 224, and the tool fixing plate 225 is disposed in the trimming space 224 in a manner that it can move along the third direction Z. Specifically, a tool driving unit 223 is disposed at the top of the trimming mechanism body 221, and the tool driving unit 223 is connected to the top of the tool fixing plate 225 along the third direction Z, and the trimming tool 222 is fixed to the bottom of the tool fixing plate 225 along the third direction Z. When trimming the second sheet 23, both sides of the second sheet 23 along the second direction Y are respectively located in the trimming space 224 of a trimming mechanism 220, and the second sheet 23 is located below the trimming tool 222, and the tool driving unit 223 drives the tool fixing plate 225 and the trimming tool 222 to trim the second sheet 23 along the third direction Z.

[0163] For example, in the embodiment of the present application, the trimming tool 222 is in the shape of an arc, so as to cut out the second sheet material 23 as follows: Figure 1b The notch 25 shown is not limited thereto and can be adjusted according to actual needs. For example, the shape of the trimming tool 222 can also be a triangle.

[0164] The embodiment of the present application does not impose any specific limitation on the specific type of the tool driving part 223 . For example, the tool driving part 223 may be a driver such as a motor or a cylinder.

[0165] The embodiment of the present application does not specifically limit the number of the trimming mechanisms 220, and can be adjusted according to actual needs. For example, in some possible implementations, the number of the trimming mechanisms 220 can also be one, three, four, or more.

Along the third direction Z, the upper first feed roller 271 and the lower first feed roller 272 are arranged at intervals, and the second sheet material 23 cut by the trimming mechanism 220 passes between the upper first feed roller 271 and the lower first feed roller 272, and the upper first feed roller 271 and the lower first feed roller 272 clamp the second sheet material 23 along the third direction Z and convey the second sheet material 23 along the feeding direction X1.

[0168] Continue to refer Fig. 9 Combined with Figure 1b and Figure 6 The cutting and clamping assembly 230 is arranged on the side of the cutting and feeding roller group 270 away from the trimming mechanism 220 along the first direction X, that is, along the first direction X, the cutting and feeding roller group 270 is located between the cutting and clamping assembly 230 and the trimming mechanism 220, and the cutting and clamping assembly 230 is used to clamp the second sheet material 23 to facilitate the cutting mechanism 240 to cut the second sheet material 23.

For example, the preset position in the embodiment of the present application refers to the upper side of the folding device 250. This arrangement allows the sheet-like tensioning member 21 formed after the cutting fixture 232 cuts the second sheet 23 to fall directly to the folding device 250, so that the folding device 250 can fold the sheet-like tensioning member 21, effectively improving the efficiency.

[0180] Exemplarily, three folding driving parts 254 are respectively provided on both sides of the bottom of the support part 251 along the first direction X. Specifically, three folding driving parts 254 are connected to the first clamping plate 252, and the other three folding driving parts 254 are connected to the second clamping plate 253.

[0189] The embodiment of the present application does not impose any specific limitation on the specific number of connecting components 266. For example, in some possible implementations, the number of connecting components 266 can also be one, or three, four, or more.

[0190] Further, the transfer device 260 has a first state and a second state.

[0191] refer to Fig.12 and Fig.15 Combined with Figure 6 , Fig.10 , Fig.13 and Fig.14 In the first state (such as Fig.12 ), the fourth direction U is the same as the third direction Z, and the adsorption portion 262 is located above the support portion 251 of the folding device 250. Fig.15 As shown), the fourth direction U is the same as the first direction X, and the adsorption portion 262 is located inside the welding machine 320.

[0192] Specifically, when the cutting moving clamping part 231 clamps the second sheet material 23 and moves along the feeding direction X1 to the top of the folding device 250, the cutting tool 241 then cuts the second sheet material 23 to form a sheet-like tensioning member 21, the sheet-like tensioning member 21 falls onto the folding device 250, and the supporting part 251 supports the middle part of the sheet-like tensioning member 21, the first clamping plate 252 supports the first part 27 of the sheet-like tensioning member 21, and the second clamping plate 253 supports the second part 28 of the sheet-like tensioning member 21.

[0193] Next, the device body 261 rotates to the first state, the adsorption portion 262 is located above the second sheet material 23 along the third direction Z, and the second sheet material 23 is located between the support portion 251 and the adsorption portion 262 along the third direction Z. Next, the folding driving portion 254 drives the first clamping plate 252 and the second clamping plate 253 to rotate toward the adsorption portion 262 to form a folding space 255, and a part of the adsorption portion 262 is located in the folding space 255.

[0194] In the above process, the first clamping plate 252 drives the first part 27 of the sheet-like tensioning member 21 to move toward the first adsorption surface 2623 so that the first part 27 is adsorbed by the first adsorption surface 2623, and the second clamping plate 253 drives the second part 28 of the sheet-like tensioning member 21 to move toward the second adsorption surface 2624 so that the second part 28 is adsorbed by the second adsorption surface 2624.

[0195] Afterwards, the folding driving unit 254 drives the first clamping plate 252 and the second clamping plate 253 to return to the initial state (i.e. Fig.11 262 is moved toward the welding station 300 along the first direction X (the fourth direction U is the same as the first direction X), and the first suction surface 2623 is upward along the third direction Z, and the second suction surface 2624 is downward along the third direction Z. Then, the transfer drive unit 263 drives the suction portion 262 to move toward the welding station 300 along the first direction X, so that the transfer device is in the second state, so as to weld the sheet-like tensioning member 21 sucked by the suction portion 262 to the first sheet 14 and the third sheet 15.

[0196] The specific structure of the welding station 300 is described in detail below with reference to the accompanying drawings.

[0197] refer to Figure 3 Combined with Figure 2The welding station 300 includes: a welding bracket 310 and a welding machine 320.

[0198] The welding bracket 310 is a substantially rectangular frame, and the welding machine 320 is connected to the welding bracket 310. The welding machine 320 includes a first welding portion 321 and a second welding portion 322, and along the third direction Z, the first welding portion 321 and the second welding portion 322 are arranged opposite to each other, and the first welding portion 321 and the second welding portion 322 can be close to each other along the third direction Z to weld the sheet-like tensioning member 21 to the first sheet material 14 and the third sheet material 15, or the first welding portion 321 and the second welding portion 322 can be away from each other along the third direction Z.

[0199] Exemplarily, an upper feed roller 330 and a lower feed roller 340 are provided on one side of the welding bracket 310 close to the cutting station 200 along the first direction X. The upper feed roller 330 is used to receive the first sheet material 14 transmitted from the first intermediate feed roller 216, and the lower feed roller 340 is used to receive the third sheet material 15 transmitted from the third intermediate feed roller 218.

[0200] The first sheet material 14 can enter between the first welding part 321 and the second welding part 322 along the feeding direction X1 through the upper feeding roller 330. The third sheet material 15 can enter the first welding part 321 and the second welding part 322 along the feeding direction X1 through the lower feeding roller 340. In addition, along the third direction Z, the first sheet material 14 is located above the third sheet material 15.

[0201] refer to Fig.15 , and combined with Figure 2 and Figure 3 After the device body 261 of the cutting station 200 is rotated to the second state, the transfer driving unit 263 drives the adsorption unit 262 to move toward the welding station 300 along the feeding direction X1, so as to move the sheet-like tensioning member 21 adsorbed by the adsorption unit 262 to between the first welding unit 321 and the second welding unit 322. In addition, the first portion 27 of the sheet-like tensioning member 21 is located between the adsorption unit 262 and the first sheet material 14 along the third direction Z, and the second portion 28 of the sheet-like tensioning member 21 is located between the adsorption unit 262 and the third sheet material 15 along the third direction Z.

[0202] Next, the first welding part 321 and the second welding part 322 move toward the adsorption part 262 along the third direction Z to weld the first part 27 of the sheet-like tension member 21 to the first sheet material 14 and the second part 28 to the third sheet material 15 to form a sheet-like tension member 21. Figure 1d The double-layer sheet 30 is shown. After welding is completed, the transfer driving unit 263 drives the adsorption unit 262 to leave the welding machine 320 along the first direction X.

[0203] In the above process, the folded sheet-like tensioning member 21 is clamped by the adsorption portion 262 and inserted between the first welding portion 321 and the second welding portion 322, so that the first part 27 can be welded to the first sheet material 14 and the second part 28 can be welded to the third sheet material 15 at the same time, which effectively improves the welding efficiency.

[0204] The welded double-layer sheet 30 enters the transfer station 400 along the feeding direction X1.

[0205] The specific structure of the transfer station 400 is described in detail below with reference to the accompanying drawings.

[0206] refer to Fig.16 and Fig.17 The conveying station 400 includes: a conveying support 410, a conveying device 420 and a material conveying moving device 430.

[0207] The conveying bracket 410 is a substantially rectangular frame. The conveying device 420 is connected to the conveying bracket 410, and the conveying device 420 is used to convey the double-layer sheet 30 along the feeding direction X1. The material transfer moving device 430 is connected to the conveying bracket 410 in a movable manner along the first direction X, and the material transfer moving device 430 and the conveying device 420 are used to synchronously convey the double-layer sheet 30 to reduce the friction force on the double-layer sheet 30, which can effectively prevent the double-layer sheet 30 from being damaged by friction.

[0208] In the embodiment of the present application, the conveying device 420 is a conveyor belt, and the conveyor belt is driven along the feeding direction X1, but is not limited thereto. In other possible embodiments, the conveying device 420 may also be other structures, such as a clamping claw or the like.

[0209] Exemplarily, the material transfer moving device 430 extends along the second direction Y, and the material transfer moving device 430 has a pressing portion 431. The pressing portion 431 is spaced apart from the conveying device 420 along the third direction Z, and the space between the pressing portion 431 and the conveying device 420 is used for the double-layer sheet 30 to pass through, and the pressing portion 431 can press down along the third direction Z to press the double-layer sheet 30 against the conveying device 420, so that the material transfer moving device 430, the double-layer sheet 30 and the conveying device 420 move synchronously to the tensioning mechanism 500 along the feeding direction X1.

[0210] The specific structure of the tensioning mechanism 500 is described in detail below with reference to the accompanying drawings.

[0211] refer to Fig.16 and Fig.17 Combined with Figure 2The tensioning mechanism 500 includes a tensioning bracket 510, two tensioning movable rollers 520, a tensioning fixed roller 530 and two tensioning conveying rollers 540. The two tensioning movable rollers 520 are used to receive the double-layer sheet 30 transmitted from the transmission station 400, and the tensioning conveying roller 540 is used to transmit the double-layer sheet 30 to the detection mechanism 600.

[0212] Among them, the tensioning bracket 510 is a roughly rectangular frame. In the embodiment of the present application, the tensioning bracket 510 and the conveying bracket 410 are integrally formed, that is, in the embodiment of the present application, the tensioning mechanism 500 and the conveying station 400 share a bracket, but the embodiment of the present application does not make specific restrictions on this. In other possible implementations, the tensioning bracket 510 and the conveying bracket 410 can be two independent brackets.

[0213] Further, the tensioning movable roller 520, the tensioning fixed roller 530 and the tensioning material transfer roller 540 all extend along the second direction Y and are rotatably connected to the tensioning bracket 510. The tensioning fixed roller 530 is rotatably connected to the top of the tensioning bracket 510 along the third direction Z. The two tensioning material transfer rollers 540 are rotatably connected to one side of the tensioning bracket 510 along the first direction X close to the detection mechanism 600.

[0214] Exemplarily, the two tensioning movable rollers 520 are rotatably connected to the tensioning bracket 510 in a movable manner along the third direction Z. Specifically, a movable roller guide rod 521 is respectively provided on both sides of the tensioning bracket 510 along the second direction Y, and the movable roller guide rod 521 extends along the third direction Z. The two ends of the two tensioning movable rollers 520 along the second direction Y are respectively connected by a movable roller connecting portion 523, and the movable roller connecting portion 523 is provided with a movable roller slider 522, and the movable roller slider 522 is connected to the movable roller guide rod 521 in a slidable manner along the third direction Z, that is, the two tensioning movable rollers 520 can move synchronously along the third direction Z.

[0215] Exemplarily, the double-layer sheet 30 is sequentially wound around two tensioning active rollers 520, a tensioning fixed roller 530 and two tensioning conveying rollers 540. The two tensioning active rollers 520 exert a downward force on the double-layer sheet 30 due to their own gravity, so that the double-layer sheet 30 is tensioned.

[0216] Furthermore, as the conveying station 400 conveys the double-layer sheet 30 to the tensioning roller 520, the tensioning roller 520 will continue to move downward. As the tensioning conveying roller 540 gradually conveys the double-layer sheet 30 to the detection mechanism 600, the tensioning roller 520 will move upward. In other words, the double-layer sheet 30 received by the detection mechanism 600 is not synchronized with the conveying station 400 conveying the double-layer sheet 30, which is conducive to the final receiving station 700 receiving the material in sections to improve efficiency. In the above process, the two tensioning rollers 520 always press down the double-layer sheet 30, so that the double-layer sheet 30 is always in a tensioned state, which is convenient for subsequent material collection.

[0217] The specific number of the tensioning rollers 520 is not specifically limited in the embodiment of the present application. For example, in other possible embodiments, the number of the tensioning rollers 520 can also be one, three, four, or more.

[0218] The embodiment of the present application does not impose any specific limitation on the specific number of the tensioning and fixing rollers 530 . For example, in other possible embodiments, the number of the tensioning and fixing rollers 530 may be two, three, four, or more.

[0219] The embodiment of the present application does not impose any specific limitation on the specific number of the tensioning transfer rollers 540. For example, in other possible embodiments, the number of the tensioning transfer rollers 540 may be one, three, four, or more.

[0222] The detection bracket 610 is a roughly rectangular frame. The detection receiving roller 630 is rotatably connected to the detection bracket 610 along the first direction X near the tensioning mechanism 500, and the detection receiving roller 630 is used to receive the double-layer sheet 30 transmitted from the tensioning mechanism 500. The detection sensor 620 is connected to the detection bracket 610, and the detection sensor 620 is used to detect whether there is a weld on the passing double-layer sheet 30 to ensure that the double-layer sheet 30 has completed the welding step before receiving the material, thereby reducing the defective rate. The double-layer sheet 30 that passes the detection is transmitted to the receiving station 700 along the feeding direction X1.

[0223] Exemplarily, in the embodiment of the present application, the detection sensor 620 is connected to the detection bracket 610 through the sensor fixing rod 621. Specifically, the sensor fixing rod 621 extends along the second direction Y, and the sensor fixing rod 621 is connected to the detection bracket 610 in a movable manner along the first direction X. The detection sensor 620 is connected to the sensor fixing rod 621 in a movable manner along the second direction Y.

[0224] The embodiment of the present application does not impose any specific limitation on the specific type of the detection sensor 620. By way of example, the detection sensor 620 may be a photoelectric sensor, an infrared sensor, or the like.

[0225] The embodiment of the present application does not impose any specific limitation on the features detected by the detection sensor 620 . For example, the detection sensor 620 can also detect features such as the pattern of the double-layer sheet 30 .

[0226] The specific structure of the material receiving station 700 is described in detail below with reference to the accompanying drawings.

[0227] refer to Figures 18 to 20 Combined with Figure 1d The material receiving station 700 includes: a material receiving bracket 710, a second movable clamping part 720, a first material receiving fixture 730, a second material receiving fixture 740, a cutting mechanism 750, a material receiving roller group 760 and a material receiving place 770.

[0228] The receiving bracket 710 is a roughly rectangular frame. In the embodiment of the present application, the receiving bracket 710 is integrally formed with the detection bracket 610, that is, the receiving station 700 and the detection mechanism 600 share a bracket. However, it is not limited thereto, and in other possible implementations, the receiving bracket 710 and the detection bracket 610 can be two independent brackets.

[0229] Exemplarily, the receiving roller set 760, the second receiving clamp 740, the cutting mechanism 750, the first receiving clamp 730 and the second movable clamping part 720 are sequentially connected to the receiving bracket 710 along the feeding direction X1. The receiving roller set 760 is located on the side of the receiving bracket 710 close to the detection sensor 620 along the first direction X. The receiving roller set 760 is used to receive the double-layer sheet 30 transmitted from the detection mechanism 600. The receiving place 770 is located below the second movable clamping part 720 along the third direction Z, and the receiving place 770 is used to receive the material.

[0230] Exemplarily, the receiving bracket 710 is provided with receiving fixed guide rails 711 on both sides along the second direction Y, the receiving fixed guide rails 711 extend along the first direction X, and the second movable clamping part 720 is connected to the receiving fixed guide rails 711 in a movable manner along the first direction X. The second movable clamping part 720 is used to clamp the double-layer sheet 30 and drive the double-layer sheet 30 to move a preset distance. The first receiving clamp 730 and the second receiving clamp 740 are used to clamp the double-layer sheet 30 when the cutting mechanism 750 cuts the double-layer sheet 30, so that the cutting mechanism 750 can cut the double-layer sheet 30 to form an inflatable semi-finished product. After cutting, the inflatable semi-finished product falls to the receiving place 770 for transportation.

[0231] It should be noted that the above-mentioned preset distance refers to the length of the inflatable semi-finished product along the first direction X after cutting. The embodiment of the present application does not impose any specific restrictions on the preset distance and can be adjusted according to the size of the inflatable product 10. For example, when the size of the inflatable product 10 is larger, the preset distance is longer.

[0232] For example, reference Fig. 20 Combined with Fig.19 The receiving roller group 760 includes an upper receiving roller 761 and a lower receiving roller 762. The upper receiving roller 761 and the lower receiving roller 762 are arranged at intervals along the third direction Z, and the double-layer sheet 30 passes between the upper receiving roller 761 and the lower receiving roller 762. The upper receiving roller 761 and the lower receiving roller 762 can clamp the double-layer sheet 30 along the third direction Z and convey the double-layer sheet 30 along the feeding direction X1.

[0233] Exemplarily, the second material receiving fixture 740 is spaced apart from the first material receiving fixture 730 along the first direction X to form a cutting channel (not shown). The first material receiving fixture 730 and the second material receiving fixture 740 both extend along the second direction Y, that is, the cutting channel extends along the second direction Y.

[0234] The first receiving clamp 730 and the second receiving clamp 740 are used to clamp the double-layer sheet 30 after the second movable clamping portion 720 moves a preset distance, so that the cutting mechanism 750 can cut the double-layer sheet 30. In addition, along the first direction X, the first receiving clamp 730 is disposed between the second movable clamping portion 720 and the second receiving clamp 740.

[0235] Exemplarily, the cutting mechanism 750 includes: a cutting tool 751, which is movably arranged in the cutting channel along the cutting channel, and the cutting tool 241 is used to cut the double-layer sheet 30 along the second direction Y after the first material receiving clamp 730 and the second material receiving clamp 740 clamp the double-layer sheet 30.

[0236] Specifically, the first material receiving fixture 730 includes: a first material receiving upper fixture 731 and a first material receiving lower fixture 732. The first material receiving lower fixture 732 is fixed to the material receiving bracket 710, and the first material receiving upper fixture 731 is arranged above the first material receiving lower fixture 732 in a manner that it can move along the third direction Z. The second material receiving fixture 740 includes: a second material receiving upper fixture 741 and a second material receiving lower fixture 742. The second material receiving lower fixture 742 is fixed to the material receiving bracket 710, and the second material receiving upper fixture 741 is arranged above the second material receiving lower fixture 742 in a manner that it can move along the third direction Z.

[0237] The double-layer sheet 30 can pass between the first material receiving upper clamp 731 and the first material receiving lower clamp 732, and between the second material receiving upper clamp 741 and the second material receiving lower clamp 742. In addition, the first material receiving upper clamp 731 can move toward the first material receiving lower clamp 732 along the third direction Z to clamp the double-layer sheet 30, and the second material receiving upper clamp 741 can move toward the second material receiving lower clamp 742 along the third direction Z to clamp the double-layer sheet 30.

[0238] The first material receiving lower clamp 732 is spaced apart from the second material receiving lower clamp 742 along the first direction X to form a lower cutting channel 753. The first material receiving upper clamp 731 is spaced apart from the second material receiving upper clamp 741 along the first direction X to form an upper cutting channel 752. When the first material receiving clamp 730 and the second material receiving clamp 740 clamp the double-layer sheet 30, the upper cutting channel 752 and the lower cutting channel 753 form a cutting channel.

[0239] The cutting mechanism 750 includes a cutting tool 751, which is arranged in the cutting channel in a movable manner along the second direction Y. When the first material receiving clamp 730 and the second material receiving clamp 740 clamp the double-layer sheet 30, the cutting tool 751 cuts the double-layer sheet 30 along the second direction Y to form an inflatable semi-finished product, and makes the inflatable semi-finished product fall to the material receiving place 770 for easy transportation.

[0240] In some possible implementations, continue to refer to Figures 18 to 20 The second movable clamping part 720 has a plurality of material receiving clamping fingers 721 facing the first material receiving clamp 730. Correspondingly, the first material receiving clamp 730 has a plurality of second avoidance grooves, and the second material receiving clamp 740 has a plurality of second clamping grooves. Each second avoidance groove is used to avoid a material receiving clamping finger 721, so that the material receiving clamping finger 721 enters the second clamping groove along the first direction X to clamp the double-layer sheet 30.

[0241] Exemplarily, the second avoidance groove includes an upper material collection avoidance groove 733 and a lower material collection avoidance groove 734 , and the second clamping groove includes an upper material collection clamping groove 743 and a lower material collection clamping groove 744 .

[0242] Specifically, the second material receiving upper clamp 741 is provided with a plurality of material receiving upper clamping grooves 743 , and the second material receiving lower clamp 742 is provided with a plurality of material receiving lower clamping grooves 744 , and each material receiving upper clamping groove 743 is arranged opposite to a material receiving lower clamping groove 744 along the third direction Z.

[0243] The first upper material receiving fixture 731 is provided with a plurality of upper material receiving avoidance grooves 733, and the first lower material receiving fixture 732 is provided with a plurality of lower material receiving avoidance grooves 734, each upper material receiving avoidance groove 733 is arranged opposite to a lower material receiving avoidance groove 734 along the third direction Z. Moreover, each lower material receiving clamping groove 744 is arranged opposite to a lower material receiving avoidance groove 734 along the first direction X.

[0244] Each upper avoidance groove 733 and each lower avoidance groove 734 is used to avoid a material receiving clamping finger 721 so that the material receiving clamping finger 721 enters the material receiving upper clamping groove 743 and the material receiving lower clamping groove 744 along the first direction X to clamp the double-layer sheet 30.

[0245] Exemplarily, when receiving the material, the receiving roller group 760 conveys the double-layer sheet 30 along the feeding direction X1, and the double-layer sheet 30 enters between the second receiving upper clamp 741 and the second receiving lower clamp 742 along the feeding direction X1. Then, the second movable clamping part 720 moves toward the second receiving clamp 740 along the first direction X, so that each receiving clamp finger 721 enters a second clamping groove to clamp the double-layer sheet 30. Then, the second movable clamping part 720 drives the double-layer sheet 30 to move above the receiving position 770 along the feeding direction X1. After that, the first receiving upper clamp 731 and the second receiving upper clamp 741 press down along the third direction Z to clamp the double-layer sheet 30, and the cutting tool 751 cuts the double-layer sheet 30 along the second direction Y to form an inflatable semi-finished product. Afterwards, the first material receiving upper clamp 731 moves away from the first material receiving lower clamp 732 along the third direction Z, so that the inflatable semi-finished product falls to the material receiving place 770 for transportation.

[0246] In summary, the sheet-like tension member welding device provided in the embodiment of the present application can automatically cut the second sheet material 23 to form the sheet-like tension member 21, weld the sheet-like tension member 21 to the first sheet material 14 and the third sheet material 15 to form the double-layer sheet material 30, and cut the double-layer sheet material 30 to form an inflatable semi-finished product, thereby effectively improving the production efficiency of the inflatable semi-finished product.
