The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Please refer to Figures 1 to 16 This utility model provides an automatic glove molding machine, including a rectangular frame 1. The rectangular frame 1 is provided with a storage rack 2, a molding frame 3 and a machine frame 4. The machine frame 4 is provided with a feeding device 5, a sensing device 6, an upper gripper device 7, an alignment device 8, a lower gripper device 9, a spreading device 10 and a moving device 11.

[0038] The storage rack 2 and the mold holder 3 are used to place the hand mold 12; the feeding device 5 is used to convey the glove 13; the sensing device 6 is located above the feeding device 5 and is used to detect the position of the glove 13 on the feeding device 5; the upper gripper device 7 is connected to the feeding device 5, grabs the glove 13 in the feeding device 5 and sends it to the alignment device 8; the alignment device 8 is used to align one end of the glove 13; the upper gripper device 7 grabs the top of the aligned glove 13 and conveys the glove 13 to the lower gripper device 9; the lower gripper device 9 grabs the bottom of the glove 13 and separates the opening of the glove 13 from the top and bottom with the upper gripper device 7; the opening device 10 is inserted into the opening of the glove 13 and opens the glove 13; the opening device 10 is located on the moving device 11, and the moving device 11 drives the opening device 10 to move the glove 13 on the opening device 10 toward the hand mold 12 on the mold holder 3.

[0039] In this embodiment of the invention, during operation, the storage rack 2 and the mold holder 3 hold the hand mold 12, and the feeding device 5 is responsible for conveying the glove 13 to the designated position. The sensing device 6, located above the feeding device 5, detects the position of the glove 13 in real time and provides feedback. The upper gripper device 7, connected to the feeding device 5, grips the glove 13 based on the feedback from the sensing device 6 and sends it to the alignment device 8. The alignment device 8 aligns one end of the glove 13, and the upper gripper device 7 then grips the top of the aligned glove 13 and conveys it to the lower gripper device 9. The lower gripper device 9 grips the bottom of the glove 13 and, in conjunction with the upper gripper device 7, separates the opening of the glove 13. Next, the spreading device 10 is inserted into the opening to spread the glove 13 open, and the moving device 11 drives the spreading device 10, causing the glove 13 to move towards the hand mold 12 on the mold holder 3, completing the mold-fitting operation.

[0040] In this embodiment, the sensing device 6 is used to detect the position of the glove 13 of the feeding device 5. Specifically, the sensing device 6 includes a rotating frame 61 and a rotary cylinder 62. The rotary cylinder 62 drives the rotating frame 61 to rotate. The rotating frame 61 is also equipped with a rotatable detection frame 63. The detection frame 63 is equipped with an electromagnetic proximity switch 64, and the rotating frame 61 is equipped with a photoelectric proximity switch 65. The photoelectric proximity switch 65 and the detection frame 63 are configured in cooperation. With the above structural configuration, when the feeding device 5 drives the material to rise, the rotary cylinder 62 drives the entire rotating frame 61 to flip towards the glove 13. The rotatable detection frame 63 contacts the glove 13 under its own weight and compacts the glove 13. As the glove 13 rises, the reaction force of the glove 13 causes the detection frame 63 to rotate in the opposite direction, which in turn triggers the photoelectric proximity switch 65. When the photoelectric proximity switch 65 is triggered, it indicates that the glove 13 is now in a compacted and horizontal state. At this time, the upper gripper device 7 can be activated and come over to grab the glove 13. The rotary cylinder 62 drives the rotating frame 61 back to the initial position, making room for the upper gripper device 7 to operate.

[0041] Compared to other large-scale automated equipment, this embodiment adopts a rectangular frame design 1, with tightly connected internal devices, a compact structure, and a reasonable overall layout, saving production space and reducing equipment footprint and production costs. Furthermore, the devices in this embodiment have clear division of labor and close cooperation, reducing manual intervention, greatly improving production efficiency, and enabling large-scale continuous production. The glove 13 gripping accuracy of this embodiment is high. By setting up a sensing device 6 to detect the position of the glove 13, it can ensure that the upper gripper device 7 can accurately grasp the glove 13 during gripping, avoiding gripping failure due to excessive distance from the glove 13 or gripping the corners, preventing the glove 13 from being placed in the preset position and affecting subsequent alignment operations. The alignment device 8 ensures that one end of the glove 13 is aligned, guaranteeing the accuracy and consistency of glove 13 fitting and improving product quality.

[0042] Preferably, the feeding device 5 includes a chain drive mechanism 51 and several feeding racks 52. The feeding racks 52 are connected to the chain drive mechanism 51, and the chain drive mechanism 51 drives the feeding racks 52 to reciprocate. The feeding racks 52 include multiple storage bins 53 for holding gloves 13. In this embodiment, the chain drive mechanism 51 is the power source for the entire feeding process and can be composed of multiple chains. The feeding racks 52, through direct and movable connections with the chains, achieve the purpose of cyclical feeding around the range of chain rotation, enabling continuous conveying of gloves 13 and quickly transporting gloves 13 from the storage position to the designated position, meeting the needs of automated production. The feeding racks 52 are equipped with multiple storage bins 53, which can store multiple gloves 13 simultaneously, playing a certain storage role, reducing frequent feeding operations, and making the production process smoother.

[0043] Preferably, the hopper 53 includes a first material plate 531 and a second material plate 532, which are slidably mounted on the loading rack 52. The loading rack 52 has a bidirectional lead screw 54 on its front side and a first linkage plate 55 and a second linkage plate 56 parallel to each other on its back side. The bidirectional lead screw 54 has a first sliding seat 57 and a second sliding seat 58. The first sliding seat 57 is connected to the first linkage plate 55, and the second sliding seat 58 is connected to the second linkage plate 56. The bidirectional lead screw 54 drives the first linkage plate 55 and the second linkage plate 56 to move in opposite directions in the horizontal direction via the first sliding seat 57 and the second sliding seat 58. In this embodiment, when the bidirectional lead screw 54 rotates, it can drive the first sliding seat 57 and the second sliding seat 58 to move closer to or further apart, realizing the opposite or forward movement of the first linkage plate 55 and the second linkage plate 56, thereby allowing the first material plate 531 and the second material plate 532 to move closer to or further apart. Through the above structural design, the spacing of multiple hoppers 53 can be quickly adjusted, and the internal space of the hopper 53 can be flexibly adjusted according to the different sizes, thicknesses, or quantities of gloves 13. When encountering larger gloves 13, the spacing of the material plates can be adjusted to make the hopper 53 fit the storage; when dealing with smaller gloves 13, reducing the spacing can improve space utilization and reduce the positional displacement of the gloves 13 during operation. In this way, when placing and retrieving gloves 13, the gloves 13 can be stably and accurately positioned in the hopper 53, reducing the shaking and displacement of the gloves 13 within the hopper 53, providing convenience for the subsequent gripper device 7 to grasp the gloves 13, and improving the success rate and accuracy of grasping. In this embodiment, the bidirectional lead screw 54 on the front of the feeding rack 52 cooperates with the linkage plate on the back, making the adjustment structure of the entire hopper 53 more stable. The lead screw drive itself has high precision and self-locking properties, ensuring that the material plate remains stable after being adjusted to the appropriate position, and will not change position due to vibration or external interference, ensuring the stability and reliability of the equipment operation.

[0044] Preferably, the upper gripper device 7 includes a first translation mechanism 71, a first lifting mechanism 72, and a gripping mechanism 73. The translation mechanism is mounted on the frame 4, the lifting mechanism is connected to the translation mechanism, and the gripping mechanism 73 is connected to the lifting mechanism. The gripping mechanism 73 is provided with gripper units 731 that cooperate with the hopper 53. The gripper units 731 are used to grip the top surface of the glove 13 in the hopper 53. In this embodiment, multiple gripper units 731 are provided, and each one corresponds to a hopper 53 in the feeding device 5, gripping the top surface of the glove 13 in the hopper 53. The first translation mechanism 71 and the first lifting mechanism 72 enable the gripper units 731 to move precisely in the horizontal and vertical directions, accurately positioning the glove 13 in the hopper 53, thus improving the accuracy and efficiency of gripping.

[0045] Preferably, the gripper unit 731 includes a gripper frame 7311, a first cylinder 7312, and a guide mechanism 7313. The first cylinder 7312 is mounted on the gripper frame 7311, and its piston rod is connected to the guide mechanism 7313. The guide mechanism 7313 includes a pair of guide plates 73131, each with a guide groove 73132 and a guide block 73133. The gripper frame 7311 contains a rotatable flipping frame 7314 and two slidable sliders 7315. Each slider 7315 has a vertically sliding connecting part 7316. The top of the connecting part 7316 engages with the flipping frame 7314, and the bottom... The component is equipped with several steel needles 7317. A first cylinder 7312 drives the guide mechanism 7313. A pair of guide plates 73131 simultaneously act on the flipping frame 7314 and two sliders 7315, causing the flipping frame 7314 to flip downwards and the two sliders 7315 to move closer together. After the flipping frame 7314 flips downwards, it pushes the connecting part 7316 downwards. The connecting part 7316 causes the steel needles 7317 to extend from the gripper frame 7311. The steel needles 7317 on the two connecting parts 7316 extend and interlock. Springs reset the two sliders 7315 and the sliders 7315 and the connecting part 7316, respectively. In this embodiment, the first cylinder 7312 drives the guide mechanism 7313, enabling the pair of guide plates 73131 to precisely control the movement of the flipping frame 7314 and the two sliders 7315, thus realizing the extension and interlocking of the steel needles 7317. The guide groove 73132 and guide block 73133 in the guide mechanism 7313 cooperate to provide stable guidance for the moving parts, reducing swaying and offset during movement. Meanwhile, the spring return design ensures that the gripper unit 731 can quickly return to its initial state after completing one gripping action, preparing for the next gripping action and improving the stability and reliability of the entire device. Furthermore, the gripper frame 7311, cylinder, guide mechanism 7313, and internal components such as the flipping frame 7314 and slider 7315 are compactly arranged, achieving complex gripping functions within a limited space, reducing the space occupied by the equipment, and facilitating the miniaturization and integration of the entire automatic glove molding machine.

[0046] Preferably, the alignment device 8 is located on the top of the frame 4, and includes a fixed plate 81, a movable plate 82, and a second cylinder 83. The movable plate 82 is slidably disposed below the fixed plate 81, and the second cylinder 83 is disposed at the bottom of the fixed plate 81, with its piston rod connected to the movable plate 82. The fixed plate 81 is provided with an alignment frame 84 that cooperates with the gripper unit 731. The gripper unit 731 places the glove 13 on the movable plate 82, and the movable plate 82 drives the glove 13 into the alignment frame 84, so that one end of the glove 13 contacts and aligns with the alignment frame 84. In this embodiment, the drive structure composed of the fixed plate 81, the movable plate 82, and the second cylinder 83 is relatively simple, and the stability and reliability of the equipment are high. Since the movable plate 82 is slidable, when the glove 13 is transferred to the movable plate 82 by the upper gripper device 7, it can move together with the movable plate 82. After the glove 13 contacts the alignment frame 84, it is aligned at the end under the guidance of the alignment frame 84. The second cylinder 83 can quickly drive the movable plate 82 to move, so that the glove 13 can complete the alignment operation in a short time, which effectively improves the production efficiency of the entire glove 13 molding process and meets the needs of large-scale production.

[0047] Preferably, the lower gripper device 9 includes a fixed gripper unit that cooperates with the gripper unit 731. The fixed gripper unit is used to grip the bottom surface of the glove 13. The fixed gripper unit includes a fixed gripper frame 91 and pneumatic fingers 92. The fixed gripper frame 91 has two slidable slide seats 93. The two grippers of the pneumatic fingers 92 are respectively connected to the two slide seats 93. The slide seats 93 have vertically sliding parts 94. The inner wall of the fixed gripper frame 91 has a groove 911 that cooperates with the sliding parts 94. The top of the sliding part 94 has several steel needles 95, and the two sides have guide shafts 96 that extend into the grooves 911. When the slider 7315 moves, the sliding part 94 moves under the action of the grooves 911. The steel needles 95 on the two sliding parts 94 pass through the fixed gripper frame 91 and are arranged alternately. In this embodiment, the fixed claw unit and the gripper unit 731 are configured to work together. During operation, the fixed claw unit can grip the glove 13 from the bottom surface, forming a coordinated action with the gripper unit 731 to firmly fix the glove 13, ensuring that the glove 13 will not slip or shift during the opening separation process, thus laying the foundation for the accuracy of the glove 13 fitting. In this embodiment, a pneumatic finger 92 drives the slide 93 to move. The sliding part 94 on the slide 93 cooperates with the groove 911 on the inner wall of the fixed claw frame 91. The guide shaft 96 extends into the groove 911, providing precise guidance for the movement of the sliding part 94, ensuring the accurate movement trajectory of the steel needle 95, allowing the steel needle 95 to accurately pass through the fixed claw frame 91 and be arranged in an alternating pattern, improving the gripping accuracy and reliability.

[0053] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a feeding device to transport gloves, an upper gripper device to grab the gloves and send them to an alignment device for alignment, and then sends the gloves to a lower gripper device to enlarge the opening. A spreading device then opens the opening, and a moving device sends the gloves into the hand mold of the mold holder. The various devices in this invention have clearly defined functions and work together to achieve highly efficient and automated production of gloves fitting into the hand mold. The feeding device is responsible for accurately transporting the gloves, and a sensing device monitors the glove position in real time to ensure a smooth process. The upper gripper device connects the feeding and alignment devices, completing the gripping, conveying, and positioning of the gloves. The alignment device ensures that one end of the glove is aligned, making the second gripping by the upper gripper device more accurate; the lower gripper device works with the upper gripper to separate the glove opening, the spreading device opens the glove, and finally, the moving device drives the opened glove to accurately fit into the hand mold. The overall structure of this invention is compact, and the process of fitting the gloves into the hand mold can be automated, reducing manual intervention, effectively improving production efficiency and mold consistency, and reducing glove production costs.
