[0052] The folding device of the first aspect embodiment and the handle production equipment of the second aspect embodiment of the present invention will now be described with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, in the embodiments of the present invention, the front-back direction is indicated as the first direction, the left-right direction as the second direction, and the up-down direction as the third direction. The first direction is the conveying direction of the handle, and the first, second, and third directions are perpendicular to each other.

[0053] The first aspect of this utility model provides a folding device 100 for a folding connector 210, see reference. Figures 1 to 3 As shown, the folding device 100 includes a body 110 and a folding mechanism 120. The body 110 is the main body of the folding device 100 and is used to support the various mechanism components. The body 110 has a support surface 1111 along the vertical direction, which is used to place and transport the handle 200. The body 110 defines receiving grooves 113 on both sides along the front-back direction, namely the left and right sides.

[0054] The folding mechanism 120 includes a rotating component 121 and a pressing block assembly 122. The rotating component 121 and the body 110 are rotatably connected, and the rotating component 121 is located in the receiving groove 113. The rotating component 121 has an abutment surface 1212 in the vertical direction. The abutment surface 1212 is located below the support surface 1111 in the vertical direction. That is, in the vertical direction, the height of the abutment surface 1212 is lower than the height of the support surface 1111. When the handle 200 is placed on the support surface 1111 and no folding operation is performed, the handle 200 will not contact the abutment surface 1212. The pressing block assembly 122 includes a first pressing block 1221 and a second pressing block 1222. The first pressing block 1221 and the second pressing block 1222 are driven by a driving component such as a cylinder or a motor, so that they can move relative to the machine body 110 and the rotating member 121 in the vertical and horizontal directions. The first pressing block 1221 and the second pressing block 1222 are arranged above the machine body 110 and the rotating member 121 in the vertical direction. The first pressing block 1221 corresponds to the abutment surface 1212 in the vertical direction, and the second pressing block 1222 corresponds to the support surface 1111 in the vertical direction.

[0055] Specifically, see Figure 4 and Figure 5 As shown, the handle 200 includes a carrying component 220 and a connecting portion 210. The connecting portion 210 is located at both ends of the carrying component 220. In the initial state, both the carrying component 220 and the connecting portion 210 are strip-shaped structures. When using the handle 200 to perform the lifting function, the connecting portion 210 needs to be folded to accommodate it in the case. The handle 200 includes a first adhesive surface 211, and the connecting portion 210 includes a second adhesive surface 212, a third adhesive surface 213, a fourth adhesive surface 214, and a fifth adhesive surface 215 connected in sequence.

[0056] In one example, see Figures 1 to 5As shown, when the connecting part 210 is folded, the handle 200 is placed on the support surface 1111. At this time, the carrying part 220 is supported by the support surface 1111, and the connecting part 210 extends out of the support surface 1111 to correspond with the abutment surface 1212 in the vertical direction. During folding, the first pressing block 1221 moves in the downward direction. Since both the first pressing block 1221 and the connecting part 210 correspond to the abutment surface 1212, during the descent of the first pressing block 1221, the first pressing block 1221 applies pressure to the connecting part 210, so that the connecting part 210 descends with the first pressing block 1221, causing the connecting part 210 to enter the receiving groove 113 and abut against the rotating part 121 located in the receiving groove 113. At this time, due to the height difference between the contact surface 1212 and the support surface 1111, a bend will occur between the connecting part 210 and the handle 200 under the action of the first pressing block 1221, that is, the second adhesive surface 212 will bend downward relative to the first adhesive surface 211. In this embodiment, when the first pressing block 1221 moves downward, the first pressing block 1221 will also move towards the second pressing block 1222 to squeeze the second adhesive surface 212, so that the second adhesive surface 212 is attached to the side wall of the body 110 and bends relative to the first adhesive surface 211, thereby improving the bending efficiency of the connecting part 210.

[0057] Then, the rotating component 121 will rotate towards the body 110. When the contact surface 1212 contacts the side wall of the body 110, the second adhesive surface 212 and part of the third adhesive surface 213 will adhere together. At this time, the fourth adhesive surface 214 and the fifth adhesive surface 215 will be located above the support surface 1111. Finally, the second pressing block 1222 will move downward to press against the fourth adhesive surface 214 and the fifth adhesive surface 215, causing the fourth adhesive surface 214 to bend relative to the third adhesive surface 213. When the second pressing block 1222 descends to contact the support surface 1111, the fifth adhesive surface 215 will bend relative to the fourth adhesive surface 214 under the pressure of the second pressing block 1222, thereby causing the fifth adhesive surface 215 to adhere to the first adhesive surface 211. At the same time, when the second pressing block 1222 moves downward, the second pressing block 1222 will also gradually move towards the first pressing block 1221, so that the fourth adhesive surface 214 is attached to the third adhesive surface 213, thereby realizing the folding of the connecting part 210.

[0058] In one example, when the rotating member 121 is flipped relative to the body 110, causing the second adhesive surface 212 and the third adhesive surface 213 to adhere, the rotating member 121 returns to its initial position. The first pressing block 1221 moves downward again to abut against the third adhesive surface 213, at which point the connecting part 210 is clamped between the first pressing block 1221 and the body 110. When the second pressing block 1222 presses against the fourth adhesive surface 214 to adhere to the third adhesive surface 213, the second pressing block 1222 moves in the direction of the second pressing block 1222 until the second pressing block 1222 abuts against the first pressing block 1221. The third adhesive surface 213 and the fourth adhesive surface 214 are together clamped between the first pressing block 1221 and the second pressing block 1222 for adhesion. The first pressing block 1221 provides support for the adhesion of the two adhesive surfaces, thereby improving the adhesion effect of the adhesive surfaces of the connecting part 210.

[0059] In related technologies, when folding the connecting part 210, it is often necessary to adjust and position the folding position of the connecting part 210, which results in low folding efficiency of the connecting part 210 and low production efficiency of the handle 200. Furthermore, adjusting the folding position can easily lead to inconsistent folding positions of the various handles 200, thereby reducing the stability of the handle 200. Compared with related technologies, the folding device 100 of this application embodiment performs specified operations on the first pressing block 1221, the second pressing block 1222, and the rotating member 121, and through the cooperation of the three, ensures that the connecting part 210 of each handle 200 is folded at the same position during the folding process. This reduces quality problems caused by folding position deviations in the connecting part 210, and improves the stability and folding efficiency of the handle 200.

[0060] In some embodiments, see Figures 3 to 6As shown, the rotating member 121 also includes an abutment portion 1211 and a bending portion 1213. The abutment portion 1211 is rotatably connected to the body 110, and an abutment surface 1212 is provided on the abutment portion 1211. The bending portion 1213 is connected to the abutment portion 1211, and the bending portion 1213 extends upward relative to the abutment portion 1211. The direction in which the abutment surface 1212 is provided is the same as the direction in which the bending portion 1213 extends. Specifically, when the abutment portion 1211 is flipped relative to the body 110, the connecting portion 210 of the handle 200 will rotate with the abutment portion 1211, and the third adhesive surface 213 and the second adhesive surface 212 will come into contact with each other and be held by the abutment portion 1211 and the side wall of the body 110. Since the bending portion 1213 extends upward, there is an included angle between the bending portion 1213 and the abutment portion 1211. The length of the connecting portion 210 in the left-right direction is greater than the length of the rotating member 121 in the left-right direction, meaning that a portion of the connecting portion 210 extends beyond the rotating member 121. When the contact surface 1212 contacts the side wall of the body 110, the connecting portion 210 is bent under the action of the bending portion 1213, thereby bending the fourth adhesive surface 214 relative to the third adhesive surface 213, so that the fourth adhesive surface 214 and the fifth adhesive surface 215 are located above the support surface 1111 in the vertical direction. By bending the portion, the bending efficiency of the connecting portion 210 can be improved, and the second pressure block 1222 can better contact the fourth adhesive surface 214 and the fifth adhesive surface 215, thereby improving the folding efficiency of the connecting portion 210.

[0061] In some embodiments, see Figures 1 to 6As shown, the body 110 includes a guide member 112 and a main body 111. The guide member 112 is disposed on both sides of the main body 111 in the front-rear direction, namely the left and right sides. The guide member 112 and the main body 111 are spaced apart, and together they define a receiving groove 113. The receiving groove 113 is located between the guide member 112 and the main body 111, and the distance between the main body 111 and the guide member 112 is the width of the receiving groove 113 in the left-right direction. The guide member 112 has a guide groove 1121 recessed on the side facing the rotating member 121 in the left-right direction, and the guide groove 1121 and the abutment surface 1212 correspond to each other in the left-right direction. Specifically, when the connecting part 210 contacts the rotating member 121 under the pressure of the first pressing block 1221, due to the length of the connecting part 210 and the pressure of the first pressing block 1221, the third adhesive surface 213 and the second adhesive surface 212 of the connecting part 210 will be bent, thereby causing the third adhesive surface 213 to contact the abutting surface 1212, and the fourth adhesive surface 214 and the fifth adhesive surface 215 to extend out of the rotating member 121. The connecting part 210 extending out of the rotating member 121 will be accommodated in the receiving groove 113. The receiving groove 113 can limit the position of the connecting part 210, ensure the correspondence between the connecting part 210 and the abutting surface 1212, and prevent the position of the connecting part 210 in the front-back direction from being offset relative to the rotating member 121, which would affect the situation where the rotating member 121 flips to bend the fourth adhesive surface 214.

[0062] In some embodiments, see Figure 2 and Figure 3 As shown, the pressing block assembly 122 also includes a fixing plate 1223. The number of fixing plates 1223 is adapted to the number of pressing blocks. Since the first pressing block 1221 and the second pressing block 1222 move to fold the connecting part 210, the function and direction of movement of the first pressing block 1221 and the second pressing block 1222 are not exactly the same. Therefore, the first pressing block 1221 and the second pressing block 1222 are respectively equipped with fixing plates 1223. The fixing plate 1223 is provided with a first channel 1224 and a second channel 1225. The first channel 1224 and the second channel 1225 are connected. After the first pressing block 1221 and the second pressing block 1222 are connected to the fixing plate 1223, they will slide along the path of the first channel 1224 and the second channel 1225, thereby moving relative to the body 110 and the rotating part 121 in the vertical and horizontal directions.

[0063] In this process, when the first pressing block 1221 moves downward, it also needs to move towards the second pressing block 1222 so that the second adhesive surface 212 contacts the side wall of the body 110 and bends relative to the first adhesive surface 211. Similarly, when the second pressing block 1222 moves downward, it also needs to move towards the direction of the first pressing block 1221 so that the fourth adhesive surface 214 adheres to the third adhesive surface 213. Therefore, the first channel 1224 and the second channel 1225 have an included angle, allowing the second channel 1225 to be offset relative to the first channel 1224, either to the left or to the right. This allows the first pressing block 1221 and the second pressing block 1222 to move downwards or gradually move laterally along the second channel 1225, satisfying the folding requirement of the connecting part 210. Furthermore, by utilizing the offset of the second channel 1225, the movement of the first pressing block 1221 and the second pressing block 1222 in the left and right directions is gradual, thereby improving the bending and bonding accuracy between the various bonding surfaces and thus improving the forming quality of the handle 200.

[0064] In some embodiments, see Figures 7 to 9 As shown, the folding device 100 also includes an indentation mechanism 130, which is positioned upstream of the folding mechanism 120 in the front-to-back direction. The indentation mechanism 130 has a first clamping block 131 and a second clamping block 132 positioned opposite each other in the vertical direction. The first clamping block 131 is connected to the machine body 110, and the second clamping block 132 is positioned above the first clamping block 131 and can move vertically relative to the first clamping block 131. This allows the first clamping block 131 and the second clamping block 132 to jointly clamp the connecting portion 210 of the handle 200, forming an indentation on the connecting portion 210. The indentation formed by the first clamping block 131 and the second clamping block 132 simplifies the bending process of the connecting portion 210 when it is conveyed to the folding mechanism 120 for folding, thereby improving the bending efficiency of the connecting portion 210 and the production efficiency of the handle 200.

[0065] Further, see Figures 7 to 9As shown, the first clamping block 131 has a first pressing rib 1311 and a second pressing rib 1312 along the vertical direction on the side facing the second clamping block 132. The second clamping block 132 has a first protrusion 1321 and a second protrusion 1324 along the vertical direction on the side facing the first clamping block 131. The first protrusion 1321 and the second protrusion 1324 are arranged between the first pressing rib 1311 and the second pressing rib 1312 in the left-right direction. The handle 200 has two opposite sides along the vertical direction. When the handle 200 is conveyed between the first clamping block 131 and the second clamping block 132, the two sides of the handle 200 will contact the first clamping block 131 and the second clamping block 132 respectively. The first pressing rib 1311 and the second pressing rib 1312 form an indentation on the lower side of the handle 200, and the first protrusion 1321 and the second protrusion 1324 form an indentation on the upper side of the handle 200.

[0066] Specifically, see Figures 1 to 9 As shown, the handle 200 has a first indentation 231, a second indentation 232, a third indentation 233, a fourth indentation 234, a fifth indentation 235, and a sixth indentation 236. The first indentation 231 is formed by pressing with a first rib 1311, and the sixth indentation 236 is formed by pressing with a second rib 1312. The first indentation 231 and the sixth indentation 236 are located on different sides of the handle 200 compared to the other four indentations. For ease of description and illustration, the indentations are shown on the same side in the accompanying drawings. The second indentation 232 and the third indentation 233 are formed by pressing with a first protrusion 1321, and the fourth indentation 234 and the fifth indentation 235 are formed by pressing with a second protrusion 1324.

[0067] In one embodiment, see Figures 1 to 9As shown, when the handle 200 is folded, the second adhesive surface 212 bends downward relative to the first adhesive surface 211 along the first indentation 231, and the third adhesive surface 213 bends upward relative to the second adhesive surface 212 along the second indentation 232 and the third indentation 233, and adheres to the second adhesive surface 212. The fourth adhesive surface 214 bends relative to the third adhesive surface 213 along the fourth indentation 234 and the fifth indentation 235, and adheres to the third adhesive surface 213. Finally, the fifth adhesive surface 215 bends relative to the fourth adhesive surface 214 along the sixth indentation 236 to adhere to the first adhesive surface 211. During the folding process in this embodiment, when the second adhesive surface 212 and the fifth adhesive surface 215 are bent, they are bent toward the outer side (lower side) of the connecting part 210, while when the third adhesive surface 213 and the fourth adhesive surface 214 are bent, they are bent toward the inner side (upper side) of the connecting part 210. This allows the adhesive surfaces to form a closed structure after bending. Therefore, the first indentation 231 and the sixth indentation 236, along with the other four indentations, need to be placed on different sides of the handle 200. The first indentation 231 and the sixth indentation 236 are located outside the closed structure, thereby improving the folding efficiency of the connecting part 210, further promoting the uniformity of the folding position of the connecting part 210, and ensuring the stability of the handle 200.

[0068] Further, see Figure 8 As shown, in some embodiments, the first protrusion 1321 and the second protrusion 1324 are spaced apart. The first protrusion 1321 includes a third reinforcing rib 1322 and a fourth reinforcing rib 1323 connected together, and the second protrusion 1324 includes a fifth reinforcing rib 1325 and a sixth reinforcing rib 1326 connected together. One end of the third reinforcing rib 1322 and the fourth reinforcing rib 1323 is connected to the second clamping block 132, while the other ends are spaced apart, i.e., the ends of the third reinforcing rib 1322 and the fourth reinforcing rib 1323 are spaced apart in the vertical direction away from the second clamping block 132. Similarly, one end of the fifth reinforcing rib 1325 and the sixth reinforcing rib 1326 is connected to the second clamping block 132, while the other ends are spaced apart, i.e., the ends of the fifth reinforcing rib 1325 and the sixth reinforcing rib 1326 are spaced apart in the vertical direction away from the second clamping block 132.

[0069] Specifically, during the folding process of the handle 200, gaps will form between the adhesive surfaces. Therefore, a reinforcing member 240 will be provided in the gaps formed by the adhesive surfaces to improve the strength of the connecting part 210. The third and fourth reinforcing ribs 1322 and 1323, and the fifth and sixth reinforcing ribs 1325 and 1326 will be spaced apart from the ends of the second clamping block 132, so that adjacent indentations can be formed on the connecting part 210. That is, the second indentation 232 and the third indentation 233 will be adjacent, and the fourth indentation 234 and the fifth indentation 235 will be adjacent. When folding the connecting part 210, due to the adjacent arrangement of the indentations, the third adhesive surface 213 will be spaced apart from the second adhesive surface 212 and the fourth adhesive surface 214, thereby reserving space to accommodate the reinforcing member 240. Furthermore, the adjacent arrangement of the indentations can increase the thickness of the accommodated reinforcing member 240, thereby increasing the structural strength of the connecting part 210 and preventing the connecting part 210 from breaking when lifting objects.

[0070] In some embodiments, see Figure 1 and Figure 9 As shown, the folding device 100 also includes a second feeding mechanism 140. Currently, the material of the handle 200 is gradually changing from plastic to paper. When the handle 200 is folded, gaps will exist between the various adhesive surfaces of the connecting part 210 due to the folding of the connecting part 210. Therefore, a reinforcing member 240 is often provided in the gaps formed by the adhesive surfaces to improve the strength of the connecting part 210. The reinforcing member 240 is also made of paper and is provided in the gaps between the third adhesive surface 213 and the second adhesive surface 212 and the fourth adhesive surface 214, respectively. One side of the reinforcing member 240 is attached to the third adhesive surface 213, and the other side is attached to the second adhesive surface 212 and the fourth adhesive surface 214. The second feeding mechanism 140 is used to transport the reinforcing member 240. The second feeding mechanism 140 is arranged upstream of the folding mechanism 120 in the front-back direction. When the handle 200 is conveyed to the second feeding mechanism 140, the reinforcing member 240 is placed on the connecting part 210 to be conveyed together with the handle 200. When the connecting part 210 is folded, the reinforcing member 240 is wrapped by the adhesive surface, thereby improving the strength of the connecting part 210 and extending its service life.

[0071] Specifically, in one example, see Figure 9As shown, the second feeding mechanism 140 includes an adsorption member 141 and a moving member 142, whereby the moving member 142 is a driving device (e.g., a motor or cylinder). The moving member 142 is connected to the adsorption member 141 to drive the adsorption member 141 to move relative to the machine body 110. When the handle 200 is conveyed to the second feeding mechanism 140, the adsorption member 141 adsorbs the reinforcing member 240 and, driven by the moving member 142, moves the reinforcing member 240 to the handle 200. Then, the reinforcing member 240 is placed on the third adhesive surface 213, so that the reinforcing member 240 is conveyed to the folding mechanism 120 along with the handle 200. When the connecting part 210 is folded, it first bends relative to the first adhesive surface 211 from the second adhesive surface 212 to begin the folding operation, and finally adheres to the first adhesive surface 211 with the fifth adhesive surface 215 to end the folding operation. The various adhesive surfaces together form a closed structure, and the reinforcing member 240 is located in the gap between the third adhesive surface 213 and the second adhesive surface 212 and the fourth adhesive surface 214, respectively.

[0072] In some embodiments, see Figure 10 and Figure 11 As shown, the conveyor belt 150 is provided with a plurality of partitions 151, which are located on the side of the conveyor belt 150 away from the support platform 510 and protrude in an upward direction. The plurality of partitions 151 are spaced apart in the front-back direction, thereby giving the conveyor belt 150 a plurality of partitioned receiving grooves 152 for accommodating handles 200.

[0073] Specifically, the handle 200 is placed in the receiving groove 152 and undergoes folding, conveying, and pressure holding steps in sequence. The partition 151 improves the safety and efficiency of the handle 200 conveying, reduces the possibility of damage, and simplifies subsequent sorting. However, since the connecting part 210 of the handle 200 enters the pressure holding cavity of the support plate 523 and the pressure holding plate 522, it comes into contact with either the support plate 523 or the pressure holding plate 522. Under the conveying force of the conveyor belt 150, the connecting part 210 is subjected to friction, which affects the conveying speed of the handle 200 to some extent. The partition 151 separates the handles 200, preventing them from stacking or tangling during conveying, thus avoiding any impact on the discharge conveying of the handles 200.

[0074] In some embodiments, the divider 151 may be detachable, and the user may adjust the distance between adjacent dividers 151 or replace dividers 151 of different heights and shapes according to the size of the transport handle 200 to meet the transportation needs of handles 200 of different sizes.

[0075] A second aspect of this utility model provides a handle production device 10, see reference.Figures 1 to 10 As shown, the handle production equipment 10 includes a first feeding mechanism 300, a gluing mechanism 400, and a folding device 100 as described in any of the above embodiments. The first feeding mechanism 300 is used to convey handles 200 that have not been folded. The gluing mechanism 400 is located downstream of the first feeding mechanism 300, and is used to receive the handles 200 conveyed by the first feeding mechanism 300 and apply adhesive to the connecting portion 210 of the handle 200. The folding mechanism 120 is located downstream of the gluing mechanism 400 in the front-back direction. The folding mechanism 120 is used to fold the glued connecting portion 210 so that the adhesive surfaces of the connecting portion 210 can fit together.

[0076] The handle production equipment 10 of this utility model uses an adhesive coating mechanism 400 to coat the connecting part 210 with adhesive to ensure accurate control of the amount of adhesive and the coating position. Furthermore, through the coordinated action of the rotating component 121 and the pressing block assembly 122, the uniformity of the folding position of each connecting part 210 is ensured, achieving the bonding and shaping of the connecting parts 210, thereby improving the production quality and efficiency of the handle 200.

[0077] Furthermore, in some embodiments, see [reference] Figures 1 to 11 As shown, the handle production equipment 10 also includes a pressure-holding mechanism 500 for clamping the connecting portion 210. The pressure-holding mechanism 500 includes a support platform 510 and a pressure-holding assembly 520. The support platform 510 is the main body of the pressure-holding mechanism 500. The pressure-holding assembly 520 includes a drive member 521, a pressure-holding plate 522, and a support plate 523. Since the two ends of the handle 200 form the connecting portion 210 by folding, and the support plate 523 is used to support the connecting portion 210 of the handle 200, in this embodiment, there are two support plates 523. The two support plates 523 are connected to the support platform 510 and are arranged on both sides of the conveyor belt 150 in the front-back direction, i.e., the left and right sides of the conveyor belt 150. In other embodiments, the number of support plates 523 can also be one, three, or four, as long as the support plates 523 can support the connecting portions 210 at both ends of the handle 200.

[0078] Furthermore, the pressure holding plate 522 is disposed circumferentially around the support plate 523 along the front-to-back direction, and the pressure holding plate 522 and the support plate 523 are spaced apart, defining a pressure holding gap between them. When the folded handle 200 is conveyed to the pressure holding mechanism 500, the connecting portion 210 of the handle 200 will be positioned within the pressure holding gap between the pressure holding plate 522 and the support plate 523, thereby achieving a pressure holding effect on the connecting portion 210. The driving member 521 is connected to the pressure holding plate 522, and the driving member 521 can drive the pressure holding plate 522 to move relative to the support plate 523, changing the pressure holding gap between the pressure holding plate 522 and the support plate 523, thereby changing the tightness of the pressure holding of the pressure holding plate 522 and the support plate 523 on the connecting portion 210. At the same time, the driving member 521 can also adapt the pressure holding plate 522 and the support plate 523 to connecting portions 210 of different thicknesses.

[0079] After the connecting part 210 is folded and formed, the handle 200 is driven by the conveyor belt 150 to be transported toward the pressure holding assembly 520. In this embodiment, there are multiple pressure holding plates 522. Since the adhesive surface of the connecting part 210 has a fitting portion in both the vertical and horizontal directions, pressure holding plates 522 are provided on the upper, left, and right sides of the support plate 523, and the pressure holding distance formed by the support plate 523 and the pressure holding plates 522 is adapted to the fitting portion of the connecting part 210. During pressure holding, the fitting portions of the first adhesive surface 211 and the fifth adhesive surface 215 are placed within the pressure holding distance in the vertical direction between the support plate 523 and the pressure holding plate 522, and the fitting portions of the second adhesive surface 212, the third adhesive surface 213, and the fourth adhesive surface 214 are placed within the pressure holding distance in the horizontal direction between the support plate 523 and the pressure holding plate 522. By pressing the mating parts with the support plate 523 and the pressure plate 522, the folded parts of the connecting part 210 will not separate or delaminate before being conveyed to the discharge port, thereby improving the production efficiency of the handle 200.

[0080] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
