Description

Technical Field

[0001] This utility model relates to a glove blank molding device and molding machine, belonging to the field of glove production technology. Background Technology

[0002] In the automated production of gloves, one of the key processes is to automatically fit the formed glove blank onto the glove mold. Currently, the automatic glove-fitting device pushes the glove blank into the glove mold along a single horizontal straight line after opening the opening.

[0003] The applicant's research revealed the following technical problems: First, the unidirectional horizontal movement forces the glove blank to be stretched unevenly during insertion, especially at the web of the hand, resulting in significant stress concentration and making it highly susceptible to tearing and damage. More seriously, this forced insertion causes enormous, uneven friction between the glove blank and the mold. This friction severely hinders the smooth sliding of the glove blank, and may even cause it to become stuck in a certain intermediate position on the mold before the die-fitting device completes its full insertion, resulting in a misaligned "false die-fitting completion." Once this occurs, even if the device continues to advance, it cannot correct the position of the glove blank, ultimately leading to complete die-fitting failure or severe wrinkling, rendering it a defective product. This results in a high die-fitting failure rate, poor stability, and a high risk of damaging the glove blank. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a glove blank molding device and molding machine that can adapt to the three-dimensional structure of glove molds, improve molding stability and molding success rate.

[0005] The glove blank molding device of this utility model includes: Translation mechanism and lifting mechanism; The mobile platform is mounted on a lifting mechanism, which in turn is mounted on a translation mechanism. The mobile platform moves in translation and lifting motions under the drive of the lifting and translation mechanisms. The mobile platform has the following features: The opening mechanism includes multiple sets of parallel support plate assemblies and an opening drive mechanism for driving each support plate assembly to open and close. Each set of support plate assemblies includes two mutually cooperating support plates. The two support plates of each set of support plate assemblies are used to extend into the glove blank and open the opening of the glove blank by moving away from each other. The clamping mechanism is provided in multiple sets. After the opening of the glove blank is opened by the opening mechanism, the clamping mechanism approaches the glove blank from the outside and cooperates with the opening mechanism to clamp the glove blank between the clamping mechanism and the opening mechanism. The clamping mechanism is mounted on the moving platform. Through a two-dimensional composite motion of translation and lifting, the device's movement trajectory actively conforms to the three-dimensional contour of the glove mold, especially adapting to the height difference between the thumb and the other four fingers. This "following" mold-fitting path fundamentally avoids forced stretching and uneven force on key areas such as the web of the hand, significantly reducing and evenly distributing the frictional force experienced by the glove blank during fitting. This eliminates jamming and "false fitting" phenomena, greatly improving the success rate and stability of mold fitting on the first attempt.

[0006] A clamping mechanism was added to provide external clamping after the glove blank is expanded. This "internal support and external pressure" clamping method greatly enhances the fixation effect on the glove blank, ensuring that the glove blank is pressed against the support plate assembly during the blank-fitting process. This provides reliable posture assurance for the glove blank to accurately execute the preset two-dimensional motion trajectory, further improving the stability of the overall machine operation, the mold-fitting accuracy, and the mold-fitting success rate.

[0007] Furthermore, during the glove fitting process, the translation mechanism first drives the moving platform horizontally, and then the translation and lifting mechanisms work together to drive the moving platform in a combined horizontal and vertical motion. Through this step-by-step action of "first horizontal movement, then combined motion," the device can smoothly slip the glove blank onto the less stressed four-finger portion first, and then gently slip the thumb portion onto it through the combined motion. This minimizes tensile stress at the web of the thumb, effectively preventing the glove blank from tearing due to stress concentration, thereby significantly reducing the product damage rate.

[0008] Furthermore, the clamping mechanism includes a clamping drive mechanism and a clamping block. The clamping drive mechanism has a clamping block at its telescopic end. The clamping drive mechanism can drive the clamping block to move up and down. When the clamping block extends, it can approach one of the support plates in at least one set of support plate assemblies, or simultaneously approach two adjacent support plates in two sets of support plate assemblies. By pressing the glove blank onto the support plate with the clamping block, a reliable posture guarantee is provided for its accurate execution of the preset two-dimensional motion trajectory, further improving the stability of the overall machine operation and the mold fitting accuracy.

[0009] Furthermore, the translation mechanism includes a first driving member, a first guide member, and a first support member, the first support member being connected to the first guide member, and the first driving member being used to drive the first support member to move; The lifting mechanism is mounted on the first support member. The lifting mechanism includes a second drive member, a second guide member, and a second support member serving as a moving platform. The second support member is slidably connected to the first support member via the second guide member. The second drive member drives the second support member to move relative to the first support member. Through the lifting and translation mechanisms, the device's movement trajectory can actively conform to the three-dimensional contour of the glove mold, particularly adapting to the height difference between the thumb and the other four fingers, or other non-planar three-dimensional glove molds.

[0010] Furthermore, the support mechanism also includes two sets of movable components that can move relative to the movable platform, namely the first movable component and the second movable component. Each set of movable components includes a left movable horizontal plate and a right movable horizontal plate that cooperate with each other. The two support plates of the support plate assembly are the left support plate and the right support plate. The left support plate is respectively set on the left movable horizontal plate, and the right support plate is respectively set on the right movable horizontal plate. The support drive mechanism includes a first support drive component and a second support drive component. The first support drive component drives the left movable horizontal plate of the first movable component and the right movable horizontal plate of the second movable component to move in opposite directions, thereby causing the corresponding left and right support plates to move relatively away from or closer to each other. The second support drive component drives the right movable horizontal plate of the first movable component and the left movable horizontal plate of the second movable component to move in opposite directions, thereby causing the corresponding left and right support plates to move relatively away from or closer to each other. When a mold-fitting failure occurs, the center line of the glove blank after opening can be laterally offset by independently controlling the first and second drive mechanisms, allowing for real-time and precise position compensation and fine-tuning. This quickly finds the optimal mold-fitting position, greatly improving the success rate and production efficiency of automated mold-fitting.

[0011] Furthermore, the support mechanism also includes two sets of movable components that can move relative to the movable platform, namely the first movable component and the second movable component. Each set of movable components includes a left movable horizontal plate and a right movable horizontal plate. The two support plates of the support plate assembly are the left support plate and the right support plate. The left support plate is respectively set on the left movable horizontal plate, and the right support plate is respectively set on the right movable horizontal plate. The two movable horizontal plates in each set of movable horizontal plate assemblies are driven in opposite directions by different drive mechanisms, thereby causing the corresponding left and right support plates to move relative to each other or closer together. This device can not only adjust the center position of the support opening, but also realize asymmetrical opening action as needed to adapt to different batches, different sizes, or slightly deformed glove blanks, thus enhancing the adaptability of the device to production changes.

[0012] Furthermore, the support mechanism also includes a third support assembly, which includes: The third positioning plate corresponds to each support plate assembly and is set between two opposing support plates; The positioning drive component is used to drive the third positioning plate to perform lifting and lowering movements. A translation plate is slidably mounted on the moving platform, and a positioning drive component is mounted on the translation plate; Positioning and translation drive components are used to drive the translation plate to perform translational movements; The third positioning plate can enlarge the opening of the glove blank under the drive of the positioning translation drive and / or the positioning drive.

[0013] A molding machine includes a frame and a hopper device, a sorting device, an opening device, a glove blank molding device, and a material handling device disposed on the frame. A silo device for storing glove blanks; The material handling device is used to move the glove blanks in the hopper device to the sorting device; A finishing device for finishing glove blanks; An opening device for opening glove blanks received from a finishing device; The glove preform fitting device is used to receive glove preforms from the opening device and fit them onto the glove mold. It not only provides a glove preform fitting device but also integrates it into a complete fitting machine system. Through the seamless connection of various functional devices (such as a sorting device for standardizing the glove preform's posture and an opening device for efficient pre-opening), previously independent processes are integrated into a smooth, automated production line.

[0014] The opening device includes an upper opening mechanism and a lower opening mechanism. The lower opening mechanism includes at least two clamping claws I arranged side by side, and the upper opening mechanism includes at least one clamping claw II. The clamping position of the clamping claw II is located between the two clamping claws I arranged side by side. The lower opening mechanism includes a support platform and an opening processing mechanism. The opening processing mechanism can drive the support platform to rotate, thereby removing the unclamped glove blank from the support platform. This effectively performs the opening operation for the glove blank and can better adapt to the glove blank molding device.

[0015] Furthermore, the sorting device includes a sorting rack, on which several sorting compartments are arranged side by side; The sorting compartment is equipped with left and right sorting claws on both sides, and two movable left and right sorting plates that move relative to the sorting frame. The left sorting plate is equipped with several left sorting claws, and the right sorting plate is equipped with several right sorting claws. The left and right sorting claws are used in a one-to-one correspondence. The sorting frame is equipped with a sorting linear drive mechanism, which drives the left and right sorting plates to move in opposite directions, thereby causing the corresponding left and right sorting claws to move away from or towards each other. The sorting compartment is open at one end, and an alignment plate is provided on the sorting rack at the other end. It also includes a sorting mechanism on the sorting rack, which moves unclamped glove blanks off the rack or places them against the alignment plate of the rack by rotating the rack. This effectively positions the glove blanks and better adapts to the opening device, thus making the gripping jaws II in the upper opening mechanism more accurate.

[0016] Furthermore, the silo device includes a silo frame, on which a first silo mechanism, a second silo mechanism, and a third silo mechanism are slidably arranged. Each silo mechanism is separately provided with a silo translation drive component, which is connected to the silo frame. The output end of the silo translation linear drive component of the first silo mechanism is connected to a material silo. At least two of the second and third silo mechanisms are also equipped with silo lifting drive components. The silo lifting drive components are respectively installed on the corresponding silo translation drive components, and the output ends of the silo lifting drive components are respectively connected to the material silos. The three material bins are driven by a bin translation drive and / or a bin lifting drive to move between the discharging position B and the retrieval position D, respectively, and avoid each other during the movement by using an avoidance position C. This active avoidance design in three-dimensional space greatly reduces the footprint required by the equipment compared to solutions that can only move horizontally, achieving a perfect combination of high-density storage and interference-free access, and improving the space utilization of the equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are: Achieving two-dimensional composite motion fundamentally solves the adaptability problem of three-dimensional molds. A clamping mechanism is added, providing external clamping after the glove blank is expanded. This "internal support and external pressure" clamping method greatly enhances the fixation effect on the glove blank, ensuring that it is pressed firmly against the support plate assembly during the blank-fitting process. This provides reliable posture assurance for its precise execution of the preset two-dimensional motion trajectory, further improving the stability of the entire machine operation, mold-fitting accuracy, and mold-fitting success rate.

[0019] Example like Figures 1 to 18 As shown, the glove blank molding device of this utility model includes: Translation mechanism 12 and lifting mechanism 13; The mobile platform is mounted on the lifting mechanism 13, which is mounted on the translation mechanism 12. The mobile platform performs translation and lifting movements under the drive of the lifting mechanism 13 and the translation mechanism 12. The mobile platform has the following features: The opening mechanism 11 includes multiple sets of parallel support plate assemblies 115 and an opening drive mechanism for driving each support plate assembly 115 to open and close. Each set of support plate assemblies 115 includes two mutually cooperating support plates. The two support plates of each set of support plate assemblies 115 are used to extend into the glove blank and open the opening of the glove blank by moving away from each other. The pressing mechanism 14 is provided in multiple sets. After the opening of the glove blank is opened by the opening mechanism, the pressing mechanism 14 approaches the glove blank from the outside and cooperates with the opening mechanism to press the glove blank between the pressing mechanism 14 and the opening mechanism. The clamping mechanism 14 and the support plate assembly 115 are arranged alternately.

[0020] The clamping mechanism 14 is mounted on the mobile platform.

[0021] During the blank-laying process, the translation mechanism 12 first drives the moving platform to move horizontally, and then the translation mechanism 12 and the lifting mechanism 13 jointly drive the moving platform to perform a compound motion of horizontal and vertical movement.

[0022] Through the two-dimensional composite motion of the translation mechanism 12 and the lifting mechanism 13, the movement trajectory of the device can actively conform to the three-dimensional contour of the glove mold, especially adapting to the height difference between the thumb and the other four fingers. This "following" mold-fitting path fundamentally avoids forced stretching and uneven force on key positions such as the web of the hand, significantly reducing and evenly distributing the friction force on the glove blank during the fitting process. This eliminates jamming and "false mold-fitting" phenomena, greatly improving the success rate and stability of mold-fitting on the first attempt.

[0023] like Figure 4 As shown, the clamping mechanism 14 includes a clamping drive mechanism 141 and a clamping block 142. The clamping drive mechanism 141 is provided with a clamping block 142 at its telescopic end. The clamping drive mechanism 141 can drive the clamping block 142 to move up and down. When the clamping block 142 extends, it can approach one of the support plates in at least one set of support plate assemblies 115, or simultaneously approach two adjacent support plates in two sets of support plate assemblies 115.

[0024] like Figure 4 As shown, the clamping drive mechanism 141 can be a cylinder, which is mounted on the mobile platform, and the extension and retraction end of the cylinder is connected to the clamping block 142.

[0025] The clamping drive mechanism 141 is a cylinder installed on the mobile platform 1. The output end of the cylinder is connected to a clamping block 142. The clamping block 142 presses against the adjacent right support plate 1152 and left support plate 1151. The two ends press against the right support plate 1152 or the left support plate 1151. After being spread open, there is only one right support plate 1152 on the right end, so it can only press against one right support plate 1152.

[0026] like Figure 2 As shown, the translation mechanism 12 includes a first driving member 122, a first guide member 123 and a first support member 121. The first support member 121 is connected to the first guide member 123, and the first driving member 122 is used to drive the first support member 121 to move. The first driving component 122 can be a motor, and the first guide component 123 can be a guide component in conjunction with a sliding component (a guide rail in conjunction with a slider). The guide component is installed on the frame, and the first support component 121 is installed on the guide component through the sliding component.

[0027] The lifting mechanism 13 is mounted on the first support member 121. The lifting mechanism 13 includes a second drive member 131, a second guide member 133, and a second support member 132, which serves as a moving platform. The second support member 132 is slidably connected to the first support member 121 via the second guide member 133. The second drive member 131 is used to drive the second support member 132 to move relative to the first support member 121.

[0028] The second driving component 131 can be a motor, and the second guide component 133 can be a guide rod in conjunction with the guide component (guide rail in conjunction with slider). The guide component is installed on the first support component 121, and the second support component 132 (i.e. the moving platform) is installed on the guide component through a sliding component.

[0029] The support mechanism 11 also includes two sets of movable components that can move relative to the movable platform, namely the first movable component and the second movable component. Each set of movable components includes a left movable horizontal plate 117 and a right movable horizontal plate 118 that cooperate with each other. The two support plates of the support plate assembly 115 are the left support plate 1151 and the right support plate 1152. The left support plate 1151 is respectively disposed on the left movable horizontal plate 117, and the right support plate 1152 is respectively disposed on the right movable horizontal plate 118. The support drive mechanism includes a first support drive member 112 and a second support drive member 114. The first support drive member 112 is used to drive the left movable horizontal plate 117 of the first movable component and the right movable horizontal plate 118 of the second movable component to move in opposite directions, thereby causing the corresponding left support plate 1151 and right support plate 1152 to move away from or towards each other. The second support drive member 114 is used to drive the right movable horizontal plate 118 of the first movable component and the left movable horizontal plate 117 of the second movable component to move in opposite directions, thereby causing the corresponding left support plate 1151 and right support plate 1152 to move away from or towards each other.

[0030] This arrangement can effectively adapt to, for example Figure 1 The installation configuration of the left-hand mold 101 and the right-hand mold 102 is shown.

[0031] like Figure 3 and Figure 4 As shown, when the motor output end of the first support drive member 112 rotates in the first direction, the motor output end drives the positive and negative lead screw 111 to rotate in the first direction. The two nuts that are adapted to the positive and negative lead screw 111 will move away from each other along the positive and negative movement of the lead screw. The left movable horizontal plate 117 of the first movable component and the right movable horizontal plate 118 of the second movable component, which are respectively connected to the two nuts, move in opposite directions, causing the left support plate 1151 on the left movable horizontal plate 117 of the first movable component and the right support plate 1152 on the right movable horizontal plate 118 of the second movable component to move away from each other. At the same time, when the motor output end of the second support drive member 114 rotates in the first direction, the motor output end drives the positive and negative lead screw to rotate in the first direction, and the two nuts that are adapted to the positive and negative lead screw will move away from each other. As the positive and negative threads move away from each other, the right movable horizontal plate 118 of the first movable component and the left movable horizontal plate 117 of the second movable component, which are respectively connected to the two nuts, move in opposite directions. This causes the right support plate 1152 on the right movable horizontal plate 118 of the first movable component and the left support plate 1151 on the left movable horizontal plate 117 of the second movable component to move away from each other. As a result, the left support plate 1151 on the left movable horizontal plate 117 of the first movable component and the right support plate on the right movable horizontal plate 118 of the first movable component move away from each other and are spread apart. The left support plate 1151 on the left movable horizontal plate 117 of the second movable component and the right support plate 1152 on the right movable horizontal plate 118 of the second movable component move away from each other and are spread apart, thereby realizing the spreading of all support plate components. At this time, the clamping block 142 presses onto the adjacent right support plate 1152 and left support plate 1151, and the ends on both sides press onto either the right support plate 1152 or the left support plate 1151. After the support plate assembly is opened, there is only one left support plate 1151 at the end, so it can only press onto one left support plate 1151.

[0032] When the forward and reverse lead screws move in opposite directions, the left support plate 1151 and the right support plate 1152 are closed.

[0033] like Figure 3 or Figure 4 As shown, the first support drive component 112 is a motor, and the output end of the motor is connected to a positive and negative lead screw 111. The threads on both sides of the positive and negative lead screw 111 are respectively connected to a matching nut 113. The nut 113 is respectively connected to the left movable horizontal plate 117 of the first movable component and the right movable horizontal plate 118 of the second movable component.

[0034] The left movable horizontal plate 117 and the right movable horizontal plate 118 are slidably connected to the moving platform through the first support guide 116. The first support guide 116 can be a guide in conjunction with a slider (a guide rail in conjunction with a slider) to install the guide on the moving platform. The left movable horizontal plate 117 and the right movable horizontal plate 118 are respectively connected to the guide through the slider.

[0035] The second support drive component 114 and the first support drive component 112 have the same structure. The nuts on the positive and negative lead screws are respectively connected to the right movable horizontal plate 118 of the first movable component and the left movable horizontal plate 117 of the second movable component.

[0036] like Figure 4 As shown, the right movable horizontal plate 118 and the left movable horizontal plate 117 also use guide components and sliding components (guide rails and sliders) to install the guide components on the moving platform. The right movable horizontal plate 118 and the left movable horizontal plate 117 are respectively connected to the guide components through sliding components.

[0037] The support mechanism 11 also includes a third support assembly 15, which includes: The third positioning plate 151 corresponds to each support plate assembly 115 and is disposed between two opposing support plates; The positioning drive component 152 is used to drive the third positioning plate 151 to perform lifting and lowering movements; the positioning drive component 152 is a cylinder, and the cylinder output end is connected to the third positioning plate 151.

[0038] A translation plate 153 is slidably disposed on the moving platform, and a positioning drive component 152 is disposed on the translation plate 153; The positioning and translation drive 154 is used to drive the translation plate 153 to perform translational movement. The positioning and translation drive 154 and the first support drive 112 have the same structure, and the nuts on the positive and negative lead screws are respectively connected to the translation plates 153 on both sides.

[0039] The translation plates 153 on both sides use guide components and sliding components (guide rails and sliders) to install the guide components onto the moving platform. The translation plates 153 on both sides are connected to the guide components through sliding components.

[0040] The third positioning plate 151 can enlarge the opening of the glove blank under the drive of the positioning translation drive 154 and / or the positioning drive 152.

[0041] A molding machine includes a frame and a hopper device 5, a sorting device 3, an opening device 2, a glove blank molding device 1, and a material handling device 4, all mounted on the frame. 5. The hopper device is used to store glove blanks; Material handling device 4 is used to move the glove blanks in the hopper device 5 onto the sorting device 3; The material handling device 4 moves the glove blanks in the hopper device 5 to the sorting device 3. The material handling device 4 includes a material handling frame, a material handling claw, and a material handling support frame. The material handling claw is a pneumatic finger and is set on the support frame. The two ends of the material handling frame are slidably connected to the frame. The material handling support frame is connected to the material handling frame through a linear drive mechanism, thereby driving the material handling support frame to move up and down. The linear drive mechanism is a synchronous belt drive, which connects the material handling support frame to the synchronous belt, thereby realizing the up and down movement of the material handling support frame.

[0042] The finishing device 3 is used to finish the glove blank; Opening device 2 is used to open the glove blank received from finishing device 3; The glove blank fitting device 1 is used to receive the glove blank from the opening device 2 and fit it onto the glove mold 100.

[0043] The opening device 2 includes an upper opening mechanism 21 and a lower opening mechanism 22. The lower opening mechanism 22 includes at least two clamping claws I 211 arranged side by side, and the upper opening mechanism 21 includes at least one clamping claw II 221. The clamping position of the clamping claw II 221 is located between the two clamping claws I 211 arranged side by side. The lower opening mechanism 22 includes a support platform 222 and an opening processing mechanism 23. The opening processing mechanism 23 can drive the support platform 222 to rotate, thereby removing the unclamped glove blank from the support platform 222.

[0044] The sorting device 3 includes a sorting rack 31, on which a plurality of sorting compartments are arranged side by side; The sorting compartment is provided with a left sorting claw 331 and a right sorting claw 321 on both sides. There are two relative sorting movable plates 33 and 32 that move relative to the sorting frame 31. The left sorting movable plate 33 is provided with a number of left sorting claws 331, and the right sorting movable plate 32 is provided with a number of right sorting claws 321. The left sorting claws 331 and right sorting claws 321 are used in a one-to-one correspondence. The sorting frame 31 is provided with a sorting linear drive mechanism 34, which is used to drive the left sorting movable plate 33 and the right sorting movable plate 32 to move in opposite directions, thereby causing the corresponding left sorting claws 331 and right sorting claws 321 to move away from or towards each other. One end of the sorting compartment is open, and the sorting rack 31 at the other end is equipped with an alignment plate 311; The sorting rack 31 consists of two support plates arranged parallel to each other, with the alignment plate 311 located at the edge of the upper support plate.

[0045] It also includes a sorting and processing mechanism 35 installed on the sorting rack 31, which moves the unclamped glove blanks out of the sorting rack 31 or makes the glove blanks abut against the alignment plate 311 of the sorting rack 31 by driving the sorting rack 31 to rotate.

[0046] The sorting and processing mechanism 35 includes a telescopic cylinder mounted on a frame. The output end of the telescopic cylinder is hinged to a push rod, which is fixed to the sorting frame 31. When the glove blank is not removed, the glove blank is removed by tilting the sorting frame 31.

[0047] The sorting and processing mechanism 35 includes a motor, the output end of which is connected to a reducer. The motor is mounted on a frame, and the output end of the reducer is equipped with a rotating shaft. The rotating shaft is fixed to the lower end face of the sorting rack 31. When the glove blank is placed on the sorting rack 31, the motor drives the reducer, thereby tilting the sorting rack 31 so that the opening of the glove blank abuts against the alignment plate 311. After the glove blank is transferred, it tilts again in the opposite direction to remove the glove blanks that have not been removed.

[0048] 5 silo device It includes a hopper frame, on which a first hopper mechanism 51, a second hopper mechanism 52 and a third hopper mechanism 53 are slidably arranged. Each hopper mechanism is provided with a hopper translation drive component. The hopper translation drive component is connected to the hopper frame. The output end of the hopper translation linear drive component of the first hopper mechanism 51 is connected to a material hopper. The second hopper mechanism 52 and the third hopper mechanism 53 are also respectively provided with hopper lifting drive components. The hopper lifting drive components are respectively set on the corresponding hopper translation drive components. The output end of the hopper lifting drive components is respectively connected to the material hopper. The three material bins are driven by a bin translation drive and / or a bin lifting drive to move between the discharge position B and the pick-up position D. During the movement, they avoid each other by passing position C.

[0049] The first hopper mechanism 51 includes guide rails installed at the left and right ends of the frame. The hopper is connected to the guide rails via a slider. It also includes a motor for driving. The output end of the motor drives a synchronous belt. The hopper is connected to the synchronous belt. The first hopper mechanism 51 is arranged at the top layer, and the hopper realizes the translation of the top layer.

[0050] Unlike the first hopper mechanism 51, the sliders of the second hopper mechanism 52 and the third hopper mechanism 53 are connected to the material hopper via a hopper lifting drive. The hopper lifting drive is a pneumatic cylinder or an electric cylinder, and the telescopic end of the hopper lifting drive is connected to the material hopper.

[0051] When the material hopper of the first hopper mechanism 51 finishes retrieving the glove blank at the retrieving position D, the material hopper translation drive moves the material hopper to the discharging position B. At this time, the material hopper of the second hopper mechanism 52 moves to the retrieving position D under the drive of the hopper translation drive, and is then raised to a suitable height by the hopper lifting drive. When the material hopper of the second hopper mechanism 52 finishes retrieving the glove blank at the retrieving position D, the material hopper descends back to the initial middle position, and the material hopper translation drive moves the material hopper back to the discharging position B. The material bin of the third material bin mechanism 53 moves to the material picking position D under the drive of the material bin translation drive. The material bin is then lifted to a suitable height by the material bin lifting drive. When the material bin of the third material bin mechanism 53 has picked up the glove blank at the material picking position D, the material bin descends back to the initial bottom position. The material bin translation drive moves the material bin back to the material dispensing position B. The material bin of the first material bin mechanism 53, which contains the glove blank, moves to the material picking position D under the drive of the material bin translation drive, thus realizing the flow of each material bin.

[0052] Work process: Material handling: The material handling device 4 accurately grabs a stack of glove blanks from the hopper device 5 and moves them to the next work station.

[0053] Finishing: The glove blank is placed into the finishing chamber of the finishing device 3. The finishing device adjusts the lateral position of the glove blank by the finishing claws, and tilts the finishing frame to align the opening of the glove blank with the alignment plate 311, standardizing the position and posture of the glove blank and ensuring that its opening direction is consistent and flat, preparing it for subsequent processes. Glove blanks that are not successfully clamped by the upper opening mechanism 21 will slide off in the opposite direction by tilting the finishing frame in the opposite direction.

[0054] Initial opening: The prepared glove blank is transferred from the upper opening mechanism 21 to the lower opening mechanism 22. The gripping claws of the lower opening mechanism hold the lower side of the opening of the glove blank, and then separate from each other, initially opening the opening of the glove blank so that the left and right support plates of the molding device can enter smoothly.

[0055] Grasping and spreading: The glove blank molding device 1 moves to the opening device position.

[0056] The support plate assembly 115 of its support mechanism 11 descends and extends into the pre-opened glove blank.

[0057] The support drive mechanism is activated, driving the support plates of each support plate assembly to move away from each other, fully opening the glove blank to the preset size.

[0058] At the same time, the clamping mechanism 14 is activated, and its clamping block 142 clamps the glove blank from the outside, firmly fixing it to the support plate.

[0059] Precision molding: The glove blank molding device 1 clamps the glove blank and begins to perform the molding action.

[0060] Phase 1: The translation mechanism 12 is activated, driving the entire moving platform to move quickly and smoothly in the horizontal direction toward the glove mold 100 until the four fingers of the glove blank are fitted into the corresponding fingertips of the mold.

[0061] Second stage: While the translation mechanism continues to move forward, the lifting mechanism 13 is activated, driving the moving platform to move downward according to the preset program. This combined "translation + descent" motion allows the thumb part of the glove blank to be precisely aligned with the glove mold 100 located below or above, and smoothly slipped on.

[0062] Detachment and repositioning: After the glove blank is fully fitted onto the glove mold: The support plate of the opening mechanism closes quickly, and the clamping block of the clamping mechanism releases simultaneously, releasing the glove blank.

[0063] The entire glove blank molding device 1 quickly retreats and resets along the reverse trajectory, ready to grab the next glove blank.

[0064] Other embodiments The support mechanism 11 also includes two sets of movable components that can move relative to the movable platform, namely the first movable component and the second movable component. Each set of movable components includes a left movable horizontal plate 117 and a right movable horizontal plate 118. The two support plates of the support plate assembly 115 are the left support plate 1151 and the right support plate 1152. The left support plate 1151 is respectively disposed on the left movable horizontal plate 117, and the right support plate 1152 is respectively disposed on the right movable horizontal plate 118. The two movable horizontal plates of each set of movable horizontal plate assemblies are driven to move in opposite directions by different drive mechanisms, thereby causing the corresponding left support plate 1151 and right support plate 1152 to move away from or towards each other.

[0065] The drive mechanism uses four sets of motors to drive four lead screws respectively. Each lead screw drives the left movable horizontal plate 117 and the right movable horizontal plate 118 of each set of movable components through a nut.

[0066] The descriptions of the structural orientations and relative positions in this invention, such as front, back, left, right, up, and down, are not intended to limit the invention and are merely for ease of description. In this invention, left and right are determined based on the left-right orientation of the glove mold; the left side of the left-hand glove mold is considered left, and the right side of the left-hand glove mold is considered right.
