Description

Technical Field

[0001] This invention relates to the field of glove manufacturing technology, and more particularly to a glove production line. Background Technology

[0002] The existing glove production line mainly includes a frame, two symmetrical and closed-loop chains moving on the frame, and sprockets driving the chains. Laterally extending hand mold rods are suspended at equal intervals on the two chains. The hand mold rods are detachably connected to the chains on both sides, for example, through chain plates or pins. The chain plates move with the closed-loop chain, and the hand mold rods also move with the closed-loop chain via the chain plates. Multiple hand molds are fixed laterally at intervals on a single hand mold rod, and glove blanks can be fitted onto the hand molds.

[0003] In actual production, the chain drives the hand mold rod through multiple stations on the glove production line, such as the dipping station, the coating station, and the drying station. Because adjacent stations or even a single station may have different requirements for the orientation of the hand mold on the rod, it is necessary to drive the hand mold rod to rotate at a specific angle to ensure the hand mold rotates accordingly. For example, at the dipping station, the hand mold needs to be inserted into or removed from the glue tank at a precise dipping angle; at the coating station, it needs to be rotated for dispensing and coating. Therefore, it is necessary to drive the hand mold rod to rotate at a specific position and lock it at a specific position. Furthermore, during the movement of the hand mold rod along the chain, there may be a need for "reversing" (i.e., the hand mold rod moving in the opposite direction) due to certain production and maintenance scenarios. For example, if the glove is damaged or jammed, or if the adhesive or coating is uneven, it needs to return to the previous station for repair or cleaning. Similarly, the need for "reversing" also exists when equipment debugging and maintenance, process parameter adjustments, quality inspection sampling, and production cycle optimization are required.

[0004] Those skilled in the art began exploring, at least 20 years ago, the problem of automating the rotation and locking of the hand mold rod on the production line, as well as how to ensure that the production line can reverse and seamlessly connect with the entire automation system.

[0005] The initial approach involves installing a motor at the desired rotation position. The motor's output shaft can selectively engage with the end of the hand mold rod. When the hand mold rod reaches a specific position, the production line stops, the motor engages with the hand mold rod, and drives the rod to rotate until the hand mold on it reaches a specific angle. Then, the motor disengages from the hand mold rod, and the production line resumes operation. While this method initially solves the problem of automatic rotation of the hand mold rod, the production line requires frequent stops and relies on automated program control, thus production efficiency still needs improvement.

[0006] To improve production efficiency without stopping the production line, an innovative approach was developed: guide rails extending along a specific trajectory are installed on the frame. The hand mold rod is supported by rolling on the guide rails, and the rotation of the hand mold rod is driven by changes in the positional relationship between the guide rails and the chain, causing the hand mold on it to be at a specific angle. The advantage of this method is that the production line does not need to be stopped, and the rotation of the hand mold rod is driven solely by a mechanical structure, requiring no external power or automation programs, resulting in a significant increase in production capacity. However, the disadvantages are that a very long guide rail is required for large rotation angles, increasing the length of the production line and the floor space required; and for certain types of gloves, the guide rail guidance results in a slower rotation speed of the hand mold rod, which cannot match the required adhesive solidification speed for the gloves, leading to an increased defect rate.

[0007] Based on the innovative idea of ​​achieving rotation through mechanical structure, a technical solution disclosed in CN214239142U has been developed. In this solution, the mounting base is fixed to the transmission chain, the hand mold rod is rotatably connected to the mounting base, and a gear is fixedly connected to the hand mold rod. A corresponding rack is provided on the frame, and a guide rod is fixedly connected to either the hand mold rod or the gear. A rotatable guide wheel is mounted on the guide rod, and a guide rail is provided on the frame to support the guide wheel. When the hand mold does not need to be rotated, the guide wheel is supported by the guide rail to ensure that the hand mold does not rotate. When the hand mold needs to be rotated, the rack drives the gear to rotate, thus rotating the hand mold. After the gear disengages from the rack, the guide wheel continues to be supported by the guide rail, ensuring that the hand mold accurately reaches the designated position before rotating, reducing the scrap rate of gloves produced by the glove dipping machine. The meshing of the gear and rack increases the rotation speed of the hand mold rod, but the drawback is that the length of the rack still needs to be set according to the rotation angle, and guide rollers are still required. Meanwhile, to more effectively ensure that the hand mold maintains its angle when rotation is not required, the mounting base is equipped with a complex locking structure including crank arms, baffles, pawls, and elastic reset mechanisms. This locking structure is prone to failure; the meshing position of the gears and rack is easily misaligned, resulting in poor rotational accuracy. Furthermore, when reversing is required, the rack mounted on the frame interferes with the reverse movement of the hand mold lever, preventing reversing while the lever is locked.

[0008] Subsequently, innovative technical solutions were developed, such as the one disclosed in CN214239142U. A mounting bracket is installed at a specific position on the frame, and the mounting bracket has one or more spaced pins. The rotary positioning assembly includes a mounting base, a support shaft, and a dial. The support shaft is mounted on the mounting base, and the dial is rotatably mounted on the support shaft. The outer wall of the support shaft has a positioning groove. The dial has at least two rotatable locking members, each with a snap-fit ​​end. Multiple locking members are used to sequentially engage with the positioning groove through the snap-fit ​​ends. The dial also has a connecting bracket for mounting a hand mold rod. Multiple notches corresponding to the locking members are provided on the edge of the dial. The pins are used to engage with the notches and actuate the locking members, causing the snap-fit ​​ends to disengage from the positioning grooves. Compared to the guide rail method and the gear and rack flipping method, the pin-driven method can quickly drive the hand mold rod to rotate without increasing the length of the production line due to the setting of guide rails or racks. However, it still cannot meet the "reversing" requirement. In actual production, gloves produced using this technical solution still have a large number of defective products, and the pass rate of first-class products needs to be improved. Summary of the Invention

[0009] (a) Technical problems to be solved

[0010] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a glove production line that solves the technical problem that glove production lines with traditional rotating components cannot quickly and reliably rotate, lock and unlock the moving hand mold rod.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0013] This invention provides a glove production line, comprising two parallel chains, a hand mold rod selectively rotatably connected between the two chains, and a fixed pin. At least one end of the hand mold rod is connected to the chain via a rotating assembly. The rotating assembly includes a mounting base fixed to the chain, two unlocking components rotatably connected to the mounting base and linked together, a locking component fixed to one of the two unlocking components, and a grooved wheel rotatably connected to the mounting base and capable of fixing the hand mold rod. Both unlocking components have unlocking parts, the locking component has a locking part, and the outer peripheral wall of the grooved wheel has multiple slots. In the locked state, the two unlocking parts and the locking part correspond to three different slots, and the locking part engages with the corresponding slot to lock the grooved wheel. In the unlocking process, as the mounting base moves with the chain, one of the unlocking parts is pressed by the pin, causing the unlocking component containing the unlocking part to rotate and symmetrically rotate the other unlocking component, while simultaneously causing the locking component to rotate, causing the locking part to disengage from the engaged slot, thus unlocking the grooved wheel.

[0014] Preferably, the multiple slots on the outer peripheral wall of the grooved wheel are arranged in two ways: Method 1: The multiple slots on the outer peripheral wall of the grooved wheel are multiple actuating grooves, which are arranged at equal intervals around the outer peripheral wall of the grooved wheel; In the locked state: the two unlocking parts and the locking part correspond to three different actuating grooves respectively, and the locking part engages with the corresponding actuating groove to lock the grooved wheel; During the unlocking process: the locking part rotates, causing the locking part to disengage from the engaged actuating groove, thus unlocking the grooved wheel; Method 2: The outer peripheral wall of the grooved wheel has multiple slots, including multiple actuating slots and multiple locking slots. The actuating slots are set at equal intervals around the outer peripheral wall of the grooved wheel, and the locking slots are set at equal intervals around the outer peripheral wall of the grooved wheel. The number of actuating slots is equal to the number of locking slots. In the locked state: the two unlocking parts correspond to two different actuating slots, and the locking part engages with a locking slot to lock the grooved wheel. During the unlocking process: the locking part rotates until the locking part disengages from the engaged locking slot, thus unlocking the grooved wheel.

[0015] Preferably, both unlocking parts are located axially between the grooved wheel and the mounting base, and the two unlocking parts are respectively located at the upper and lower ends of the grooved wheel and facing the actuation groove towards the actuation pin; the locking part is located on the circumference of the grooved wheel. In the first configuration, the locking part engages with the actuation groove facing the actuation pin to lock the grooved wheel; in the second configuration, the locking part engages with the locking groove facing the actuation pin to lock the grooved wheel. A reset part is also included. During the unlocking process: the reset part stores force; the locking process is as follows: after the grooved wheel is unlocked, the mounting base moves with the chain... During operation, the actuation groove corresponding to the unlocking part pressed by the actuation pin is pushed by the actuation pin, thereby driving the grooved wheel to rotate; in the first configuration, when the outer circumference of the grooved wheel moves along the locking part to the next actuation groove aligned with the locking part, the reset member drives the locking part to automatically reset to engage with the actuation groove; in the second configuration, when the outer circumference of the grooved wheel moves along the locking part to the next locking groove aligned with the locking part, the reset member drives the locking part to automatically reset to lock with the locking groove; during the resetting process of the locking part, the reset member drives the unlocking part to automatically reset to the next actuation groove aligned with the original corresponding actuation groove.

[0016] Preferably, when the number of actuating slots is 4, setting method 2 is selected; when the number of actuating slots is 6 or more, setting method 1 is selected; and when the number of actuating slots is less than or equal to 10.

[0017] Preferably, the pin can rotate between a shifting position and a yielding position; when the chain moves forward, the pin is in the shifting position and can press the unlocking part; when the chain moves backward, the unlocking part pushes the pin from the shifting position to the yielding position, and the pulley remains locked.

[0018] Preferably, the pin is rotatably connected to the pin plate via a rocker arm, and the rocker arm has a rotating end and a swinging end; the rotating end is pivotally connected to the pin plate, and the pin is fixed to the swinging end; the stop is fixed to the pin plate and abuts against the swinging end or the side wall of the pin facing away from the direction in which the pulley approaches when the chain moves in the forward direction.

[0019] Preferably, the reset member is connected to at least one of the two unlocking members; during the unlocking process: the reset member stores force as the unlocking member rotates.

[0020] Preferably, the reset element is a U-shaped spring, with its two ends connected to the opposite ends of the two unlocking elements; or the reset element is a compression spring, with its two ends connected to the two unlocking elements.

[0021] Preferably, the two unlocking components are symmetrical crank arms, with the openings of both components facing the grooved wheel, and the corners are respectively hinged to the upper and lower ends of the mounting base, with the opposite ends forming unlocking parts; wherein: the proximal ends of the two unlocking components are linked together; each of the proximal ends of the two unlocking components is provided with a semi-circular groove, and a cylindrical pin is embedded in the circular groove formed by the two semi-circular grooves to form a linkage between the proximal ends of the two unlocking components; or the proximal ends of the two unlocking components are provided with interlocking protrusions to form a linkage between the proximal ends of the two unlocking components; or the two unlocking components are hinged to both ends of the connecting rod to form a linkage between the two unlocking components.

[0022] Preferably, both unlocking components include an L-shaped arm composed of a horizontal arm and a vertical arm, both of which are perpendicular to the axial direction of the grooved wheel. The connection between the horizontal and vertical arms forms a corner of the unlocking component. In the locked state, the two unlocking components are symmetrically connected vertically to form a semi-rectangular frame shape. The ends of the vertical arms of the two unlocking components away from the horizontal arms form the near ends of the two unlocking components, and the ends of the horizontal arms of the two unlocking components away from the vertical arms form the opposite ends of the two unlocking components. The unlocking part is a trapezoidal protrusion formed by extending outward from the end of the horizontal arm away from the vertical arm. The locking component includes a vertical plate, which is parallel to the vertical arm of one of the two unlocking components. The locking component also has a fixing part located at one end of the vertical plate for fixing to either of the two unlocking components. The locking part is a locking block formed by extending radially from the other end of the vertical plate toward the axis of the grooved wheel. The fixing part is adjacent to the position where the two unlocking components are linked together.

[0023] (III) Beneficial Effects

[0024] The beneficial effects of this invention are:

[0025] This invention discloses a glove production line that mechanically and rigidly locks the angle of the hand mold rod when the grooved wheel is in the locked state by directly engaging the locking part of the locking component with a groove on the outer peripheral wall of the grooved wheel. This effectively solves the problems of uneven load distribution, inaccurate locking position of some locking components due to individual parts and assembly errors, large assembly gaps, and reduced locking accuracy caused by multiple locking components in the prior art. It also effectively prevents accidental rotation of the hand mold rod due to chain vibration or vibration during production, ensuring reliable locking and guaranteeing the positioning accuracy of the glove at each workstation. Furthermore, the unlocking of the locking component is controlled by two interlocking unlocking components. During the movement of the chain in the production line, one of the unlocking components can be pressed by a fixed pin, thereby triggering the unlocking of the locking component. This allows the trigger point to be set on the upper or lower side of the grooved wheel's travel path according to actual production needs, providing greater flexibility in the process layout of the production line. The entire device is compact, easy to use, and applicable to various glove production lines, thus broadening its application range. Attached Figure Description

[0050] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "up," "down," "left," and "right" are used interchangeably. Figure 1 The orientation is used as a reference.

[0051] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0052] Example 1:

[0053] In existing technologies, the pin-operated mechanism can quickly drive the hand mold rod to rotate without increasing the production line length due to the installation of guide rails or racks. It also effectively avoids the problem of misalignment during gear and rack meshing, which requires frequent zeroing and correction. However, in actual production, gloves produced using this technology still have a high defect rate, making it suitable only for producing second-grade products with lower quality requirements. Consequently, the pass rate and production efficiency for first-grade products with higher quality requirements still cannot meet production needs, and numerous malfunctions still occur during use.

[0054] Through extensive research, the inventors of this invention discovered that existing lever designs suffer from high defect rates and high failure rates. The main reason for this is the poor overall fit of the locking mechanism in the original rotating assembly. This mechanism features multiple locking elements, each corresponding to a specific notch on the dial. These locking elements engage with a positioning groove on a fixed spindle to achieve locking at different angles. However, these locking elements must precisely align with the unique positioning groove when the dial is rotated to a specific angle. If there are machining / assembly errors in the circumferential distribution angle of the locking elements, some elements may not fully engage with the positioning groove. This can lead to excessive load on some elements, causing overload deformation. Furthermore, misaligned locking elements will rub against the edge of the positioning groove, accelerating wear and requiring additional force to unlock. Simultaneously, during the dial's rotation, centrifugal force or vibration may cause slight misalignment of the locking elements, further deteriorating the engagement. Therefore, to ensure the proper functioning of the unlocking mechanism, a large gap is required at the point where the locking component mates with the positioning groove to accommodate deviations. In other words, the width of the positioning groove must cover the maximum expected deviation. However, excessive gaps will sacrifice locking rigidity, reduce the accuracy of the locking angle, and may even cause shaking or abnormal noise. Furthermore, errors in the spindle position caused by excessive gaps will be amplified radially on the dial, resulting in a larger rotation angle deviation on the dial. This radial error severely affects the dial's angle flipping accuracy, impacting product quality. Simultaneously, the maintenance of this rotating assembly is complex. Each locking component wears at different rates, requiring periodic individual adjustment or replacement; otherwise, the overall locking performance will be affected. These problems prevent the original rotating assembly from accurately locking at the required angle during rotation, directly leading to a high product defect rate and susceptibility to malfunctions during use, affecting production schedules and reducing production efficiency.

[0055] In view of this, in order to minimize the deviation of the rotation angle without increasing the length of the production line and to ensure reliable locking at a specific angle, thereby improving the product qualification rate, the inventors of this invention have conducted in-depth research on the aforementioned problems in the prior art and, with years of experience in research and manufacturing in related industries, actively sought solutions. After long-term research and development efforts, they have finally successfully developed a glove production line of this invention to improve the problems of the prior art.

[0056] Reference Figures 1 to 7This embodiment proposes a glove production line, specifically a glove dipping machine, comprising a frame, two symmetrical parallel chains 10 that move in a synchronous closed loop, hand mold rods 20 equidistantly suspended between the two chains 10, multiple pins 6, and a rotating assembly. The chains 10 are movably mounted on the frame via sprockets. The hand mold rods 20 extend laterally, with one end rotatably connected to one chain 10 and the other end connected to another chain 10 via the rotating assembly described in detail below, allowing the hand mold rods 20 to be selectively rotatably connected between the two chains 10.

[0057] Chain 10 drives hand mold rod 20 through multiple stations on the glove production line, such as the dipping station, the coating station, and the drying station, to process the gloves. The chain 10 moves in a forward direction. At stations where the hand mold rod 20 needs to rotate at a certain angle, a fixed pin 6 is installed. "Fixed position" means that the pin 6 does not move with the chain 10 and is fixed in position relative to the frame. For example, the pin plate 9 can be fixed to the crossbeam of the frame, or the pin 6 can be directly connected to the crossbeam of the frame. The rotation of the hand mold rod 20 is selected by the cooperation of the rotating component and the pin 6.

[0058] The rotating assembly includes a mounting base 1, a grooved wheel 2, two unlocking parts 3, a locking part 4, and a resetting part 5.

[0059] Mounting base 1 is detachably connected to chain 10 via chain plates or pins, and can move synchronously with chain 10. This mounting base 1 serves as the mounting foundation for movable parts such as pulley 2, unlocking component 3, locking component 4, and resetting component 5, which are mounted on chain 10. It directly integrates the movable parts of the rotating assembly with the power transmission part of the production line, ensuring the synchronization of the movable parts with the production line. Mounting base 1 can be the chain plate itself on chain 10, or it can be an independent component fixedly connected to the chain plate. The rotating assembly is an integrated unit, installed at the specific location in the production line where rotation is required.

[0060] The Geneva wheel 2 is used to fix the hand mold rod 20, and is located between the hand mold rod 20 and the mounting base 1. The Geneva wheel 2 is rotatably connected to the middle position of the mounting base 1 on the side facing the hand mold rod 20. Specifically, a fixed shaft 11 is fixed on the mounting base 1 at the position corresponding to the Geneva wheel 2. The Geneva wheel 2 is rotatably connected to the fixed shaft 11 via bearings, allowing the Geneva wheel 2 to rotate freely around the fixed shaft 11. The axis of the fixed shaft 11 is the axis of rotation of the Geneva wheel 2. This connection structure allows the fixed shaft 11 to bear the main load of the hand mold rod 20 and the glove blank (including the hand mold), while the Geneva wheel 2 mainly functions to transmit torque. Therefore, it effectively improves the load-bearing capacity and service life of the mechanism.

[0061] The grooved wheel 2 is rotatably connected to the mounting plate 1, but it can switch between a locked and unlocked state. When locked, the grooved wheel 2 cannot rotate relative to the mounting base 1; when unlocked, it can rotate relative to the mounting base 1, thus driving the hand mold rod 20 to rotate, and their movements are synchronized. Therefore, controlling the rotation of the grooved wheel 2 or locking it at a certain angle is equivalent to controlling the rotation and locking of the hand mold rod 20. Simultaneously, the grooved wheel 2 moves with the mounting base 1, meaning the hand mold rod 20 moves with the mounting base 1.

[0062] The rotating assembly only needs to be mounted on one of the two chains 10 to achieve the controllable rotation of the hand mold rod 20. Of course, both ends of the hand mold rod 20 can be connected to the chain 10 via the rotating assembly, with both ends serving as the rotation drive ends, making the rotation of the hand mold rod 20 less strenuous. However, the installation accuracy of the rotating devices on both sides and the corresponding pins 6 on both sides needs to be ensured. Therefore, it is preferable to connect only one end to the rotating assembly. The connection structure between the grooved wheel 2 in the rotating assembly and the hand mold rod 20 is not an improvement of this invention and can be achieved using existing technology. In this embodiment, the hand mold rod 20 is formed in an n-shape by connecting the crossbeam suspending the hand mold and the swing arms on both sides. One swing arm is fixed to the middle of the grooved wheel 2 in the rotating assembly, and the axis of rotation of the grooved wheel 2 is the axis of rotation of this swing arm. The other swing arm can be rotatably connected to the chain 10 on the other side through any rotatable connection method, ensuring that the axis of this rotatable connection is coaxial with the axis of rotation of the grooved wheel 2.

[0063] Figure 2 As clearly shown, the grooved wheel 2 is disc-shaped, and its outer peripheral wall is provided with multiple actuating grooves 21 at equal intervals. The actuating grooves 21 are U-shaped grooves that are recessed inward from the outer peripheral wall of the grooved wheel 2. In this embodiment, there are 8 actuating grooves 21, that is, the included angle between the center lines of adjacent actuating grooves 21 is 45°, and the interval angle between adjacent actuating grooves 21 on the actuating groove 2 is 45°. Of course, the present invention is not limited to this. The outer peripheral wall of the grooved wheel 2 is provided with only actuating grooves 21 for both driving rotation and locking (detailed later). The number of actuating grooves 21 is preferably greater than or equal to 6 and less than or equal to 10, and is an even number, such as 6, 8, 10, etc.

[0064] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the pin plate 9 corresponds to a workstation. Three pins 6 are evenly spaced and at the same height on the pin plate 9. These three pins 6 are located above the travel path of the grooved wheel 2, which moves with the chain 10 to this workstation. They are used to unlock and move the grooved wheel 2 when it moves close to the pins 6. Specifically, unlocking the grooved wheel 2 requires the pins 6 to drive two unlocking components 3 in a coordinated manner. In this embodiment, the two unlocking components 3 are a first crank arm 34 and a second crank arm 35 symmetrically arranged vertically. The first crank arm 34 and the second crank arm 35 are both located between the grooved wheel 2 and the mounting base 1 along the axial direction of the grooved wheel 2. The wall surface of the first crank arm 34 and the second crank arm 35 facing the mounting base 1 is slidably connected to the plate surface of the mounting base 1. Space is left between the grooved wheel 2 and the mounting base 1 for the first crank arm 34 and the second crank arm 35 to move, ensuring no movement interference between the moving parts and making the structure more compact. The first crank arm 34 and the second crank arm 35 each have only one horizontal arm 31 and one vertical arm 32, forming an L-shaped arm. Both the horizontal arm 31 and the vertical arm 32 are perpendicular to the axial direction of the Geneva wheel 2. Thus, the two unlocking members 3 are symmetrically arranged in a crank arm shape, with the openings of both unlocking members 3 facing the Geneva wheel 2. Furthermore, the first crank arm 34 and the second crank arm 35 are both located on one side of the Geneva wheel 2's traveling direction, that is, on the side facing the direction of approach to the derailleur 6. In this embodiment, when the chain 10 moves forward, the Geneva wheel 2... Figure 2 , Figure 3 , Figure 5 and Figure 6 The movement proceeds from left to right. When it is not in contact with the pin 6, the pin 6 is located on the right side of the grooved wheel 2, and both the first crank arm 34 and the second crank arm 35 are located on the right side of the grooved wheel 2. The opening of the first crank arm 34 faces left and down, and the opening of the second crank arm 35 faces left and up.

[0065] Furthermore, the corners of the first crank arm 34 and the second crank arm 35 (i.e., the connection between the horizontal arm 31 and the vertical arm 32) are respectively hinged to the upper and lower ends of the mounting base 1. Thus, the hinge points at the corners of the first crank arm 34 and the second crank arm 35 constitute the rotation centers of the first crank arm 34 and the second crank arm 35, so that the two unlocking parts 3 are rotatably connected to the mounting base 1.

[0066] The end of the vertical arm 32 of the first crank arm 34 furthest from its horizontal arm 31, and the end of the vertical arm 32 of the second crank arm 35 furthest from its horizontal arm 31, form the near ends of the first crank arm 34 and the second crank arm 35, that is, the near ends of the two unlocking components 3, which are linked together. Specifically, a semi-circular groove 321 is provided at the end of each of the two vertical arms 32 furthest from their respective connected horizontal arms 31. The two semi-circular grooves 321 are arranged opposite each other, forming a circular groove. A cylindrical pin 33 is embedded in the circular groove, and the two can rotate relative to each other. When either vertical arm 32 moves toward or away from the groove wheel 2, it can drive the other vertical arm 32 to move synchronously toward or away from the groove wheel 2 through the transmission of the cylindrical pin 33. That is, one vertical arm 32 drives the other vertical arm 32 and the cylindrical pin 33 to move synchronously. The cylindrical pin 33 has a simple structure, is easy to process, and provides a reliable rotational connection, ensuring the synchronicity of the movement of the two vertical arms 32. Thus, through the cooperative design of the semi-circular grooves 321 at the near ends of the two vertical arms 32 and the cylindrical pins 33, the two unlocking components 3 are linked together. Of course, for this linkage, the end faces of the near ends of the two vertical arms 32 form inclined surfaces that are far apart from each other outside the semi-circular grooves 321 near the groove wheel 2. This can avoid the problem of mutual interference when the two vertical arms 32 move. At the same time, when the inclined surfaces of the two vertical arms 32 abut against each other, the two vertical arms 32 are in contact with each other and can no longer move in the direction away from the groove wheel 2, thus constituting a limit on the linkage of the two unlocking components 3.

[0067] Continue to refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 In the locked state, the two L-shaped unlocking components 3 are symmetrically connected vertically to form a semi-rectangular frame. The mounting base 1 is also a rectangular plate. The semi-rectangular frame formed by the two unlocking components 3 matches the edge of the rectangular mounting base 1. That is, the horizontal arms 31 of the two unlocking components 3 are flush with the upper and lower edges of the mounting base 1, and the vertical arms 32 of the two unlocking components 3 are flush with one vertical side of the mounting base 1. The structure of this product is neat. Of course, the mounting plate 1 is not necessarily a complete rectangular plate. In its non-stressed position, process holes can be appropriately opened for weight reduction and installation clearance. Here, it is worth noting that the mounting plate 1 and the two unlocking components 3 are arranged in a matching rectangular shape, making the overall structure neater and facilitating the installation of each component.

[0068] Furthermore, an unlocking portion 311 is formed at one of the opposite ends of the two unlocking members 3. In this embodiment, the end of the horizontal arm 31 of the first crank arm 34 away from its vertical arm 32, and the end of the horizontal arm 31 of the second crank arm 35 away from its vertical arm 32, constitute the opposite ends of the two unlocking members 3. A trapezoidal protrusion extending outward from this end constitutes the unlocking portion 311. The trapezoidal protrusion gradually tapers outward (i.e., it has chamfers on both sides). Specifically, it can be understood that a trapezoidal protrusion is provided on the upper side of the end of the horizontal arm 31 of the first crank arm 34 away from the vertical arm 32; a trapezoidal protrusion is also provided on the lower side of the end of the horizontal arm 31 of the second crank arm 35 away from the vertical arm 32. When the trapezoidal protrusion is pressed in the vertical direction from the outside to the inside of the grooved wheel 2, the trapezoidal protrusion moves inward, and the horizontal arm 31 rotates inward around the position where it is hinged to the mounting base 1. The upper horizontal arm 31 rotates counterclockwise, and the lower horizontal arm 31 rotates clockwise.

[0069] Simultaneously, the unlocking parts 311 of the two unlocking components 3 correspond to the actuation grooves 21 located at the upper and lower ends of the grooved wheel 2 and facing the direction of the actuation pin 6. When the grooved wheel 2 moves with the mounting base 1 to approach the actuation pin 6, the actuation pin 6 first presses the unlocking part 311. The pressure of the actuation pin 6 on the trapezoidal protrusion pushes the horizontal arm 31 to move towards the direction of the grooved wheel 2. At this time, the vertical arm 32 moves away from the grooved wheel 2, thereby driving the locking component 4 to move away from the grooved wheel 2, thus unlocking the grooved wheel 2. At this time, the actuation pin 6 enters the actuation groove 21 of the grooved wheel 2 and actuates it, causing the grooved wheel 2 to rotate at a certain angle. The trapezoidal protrusion facilitates the movement of the horizontal arm 31, and the chamfers on both sides make its contact and disengagement with the actuation pin 6 smooth and easy, reducing impact and wear, and is suitable for high-speed continuous production cycles. The unlocking part 311 can directly cooperate with the pin 6 fixed to the frame to realize the unlocking function. That is, the pin 6 has the dual functions of rotating the groove wheel 2 and unlocking, without the need to set other triggering components, making the structure simpler.

[0070] Furthermore, refer to Figure 2 and Figure 4 The locking component 4 is fixed to one of the two unlocking components 3, and the two are rigidly connected and move synchronously, so that the locking action is directly transmitted without delay. In this way, the two unlocking components 3 and the locking component 4 are linked together.

[0071] Specifically, the locking member 4 includes a vertical plate, which is parallel to the vertical arm 32 of one of the two unlocking members 3. In this embodiment, the width of the vertical plate is the same as the width of the vertical arm 32. The locking member 4 has a fixing part 42 and a locking part 41. The fixing part 42 is located at one end of the vertical plate and is used to connect with the unlocking member 3; the locking part 41 is a locking block formed by extending radially from the other end of the vertical plate toward the axis of the grooved wheel 2. The shape of the locking part 41 matches the shape of the actuation groove 21 of the grooved wheel 2. When it is embedded in the actuation groove 21, it can make close contact with the actuation groove 21, effectively preventing the grooved wheel 2 from rotating in any direction, and the locking is stable and reliable. In this embodiment, the fixing part 42 includes a through hole on the vertical plate and a bolt that passes through the through hole. The bolt is connected to the lower part of the vertical arm 32 of the first crank arm 34 located below. The vertical plate extends to cover the upper part of the vertical arm 32 of the second crank arm 35 below, that is, to cover the linkage connection position of the first crank arm 34 and the second crank arm 35.

[0072] Of course, this embodiment is not limited to this. In other embodiments of the present invention, the fixing part 42 can also be fixed on the lower of the two unlocking parts 3. In order to simplify the structure and improve the driving accuracy, the installation position of the fixing part 42 is adjacent to the position where the two unlocking parts 3 are linked.

[0073] Therefore, the locking member 4 is located on the periphery of the grooved wheel 2, and the locking part 41 engages with the actuation groove 21 facing the direction of approach to the pin 6 to lock the grooved wheel 2. When the vertical arm 32 moves towards the grooved wheel 2, the locking part 41 engages with the actuation groove 21 of the grooved wheel 2 to lock the rotation of the grooved wheel 2; when the vertical arm 32 moves away from the grooved wheel 2, the locking part 41 disengages from the actuation groove 21 of the grooved wheel 2 to unlock the grooved wheel 2. Moreover, as can be seen from the figure, when there are 8 actuation grooves 21, among the 4 actuation grooves 21 facing the pin 6: the two actuation grooves 21 located at the upper and lower ends correspond to the unlocking parts 311 of the two unlocking members 3 respectively, the actuation groove 21 located diagonally downward engages with the locking part 41 of the locking member 4, and there is one actuation groove 21 that does not correspond to the unlocking part 311 and the locking part 41. Among them, the locking part 41 and the unlocking part 311 are offset along the axial direction of the grooved wheel 2.

[0074] Of course, it is reasonable to understand that in other embodiments of the present invention, if there are 6 actuating slots 21, in the 3 actuating slots 21 facing the pin 6: the two actuating slots 21 located at the upper and lower ends correspond to the unlocking parts 311 of the two unlocking members 3 respectively, and the actuating slot 21 located on the right side engages with the locking part 41 of the locking member 4. At this time, the locking part 41 is basically located at the position where the two unlocking members 3 are linked.

[0075] In summary, the locking member 4 is in a fixed position and can move towards / away from the grooved wheel 2 in two directions, following the unlocking member 3. During the rotation of the grooved wheel 2, the locking member 4 can selectively lock when a certain actuation groove 21 rotates to its corresponding position, thus locking the grooved wheel 2 at multiple angle positions to adapt to the different needs of the hand mold orientation at different workstations and improve the flexibility of the production line. At both the upper and lower ends of the grooved wheel 2, the locking member 4 can be driven to rotate by the unlocking member 3, causing the locking member 4 to abut against or disengage from the actuation groove 21 of the grooved wheel 2, thereby locking or unlocking the rotation of the grooved wheel 2. More importantly, it can cooperate with the pin 6 fixed to the frame, so that the pin 6 has the dual function of actuating the rotation of the grooved wheel 2 and unlocking. After the pin 6 presses the unlocking member 3 to unlock, it then actuates the grooved wheel 2, causing the hand mold rod 20 to rotate at a specific angle for operations such as applying glue evenly and dripping glue. The two actions of unlocking and rotating are closely coordinated by the same pin 6, which can effectively reduce the failure rate of the entire equipment. Furthermore, clockwise or counterclockwise rotation and precise adjustment of the rotation angle can be achieved by staggering at least one pin 6 above and / or below the grooved wheel 2. The angle between adjacent rotation slots is the same as the angle of rotation of the grooved wheel 2 after a single rotation. Therefore, the number of rotation slots 21 can be set according to the actual needs of the production line. For example, with 8 rotation slots, a single rotation will rotate the hand mold rod 20 by 45 degrees. To rotate the hand mold rod 20 by 90 degrees, two pins 6 can be placed at intervals in the same position, with the interval between the two pins 6 matching the distance between two adjacent rotation slots 21. In other words, the number of rotation slots 21 on the grooved wheel 2, the placement position (upper / lower end) of the pins 6, and the number of pins 6 placed in the same position can all be adjusted according to actual needs. Meanwhile, the pin 6 is preferably detachably fixed to the frame by the pin plate 9, and then several pin plates 9 with different numbers of pins 6 are set. The appropriate pin plate 9 is selected and installed in the corresponding position of the frame according to the actual needs of the production line; or several slots for inserting pins 6 are set on the pin plate 9, and then the position and number of pins 6 are selected according to the actual needs of the production line, thereby improving the overall adaptability of the equipment, reducing the number of parts, and reducing production costs.

[0076] Traditional methods, which use multiple locking elements corresponding to a single positioning groove, can only set trigger points on one side to match the position of the positioning groove, failing to meet the requirement of triggering from either the top or bottom. Furthermore, if the trigger element is a pin 6 fixed to the frame to rotate the grooved wheel 2, only rotation in one direction is possible, not both forward and reverse rotation. To achieve rotation in both directions, a separate unlocking trigger element is required, further leading to misalignment between the triggering and unlocking actions, resulting in a complex structure and high failure rate. Therefore, this embodiment, compared to this traditional rotating assembly, uses a symmetrical drive structure (a first crank arm 34 and a second crank arm 35 that can be linked), enabling unlocking regardless of whether the grooved wheel 2 is triggered from above or below. Unlocking can be directly achieved through the pin 6 fixed to the frame (the pin 6 serves the dual function of rotating the grooved wheel 2 and unlocking). This allows the pin 6 to be positioned above or below the grooved wheel 2 as needed, satisfying the requirement of driving the grooved wheel 2 to rotate in both directions. Therefore, this single-point triggering and dual-side linkage method can better adapt to the need for drive points to be arranged on both sides of the production line, simplifying the production line layout.

[0077] Furthermore, in this embodiment, the reset of the first crank arm 34 and the second crank arm 35 after being pressed by the pin 6, that is, the reset of the locking member 4, is achieved by the reset member 5. The reset member 5 is located between the mounting base 1 and the grooved wheel 2 along the axial direction of the grooved wheel 2. In this embodiment, the reset member 5 is a U-shaped spring, the middle part of which passes through the limiting ring fixed on the mounting base 1, and its two free ends are respectively inserted horizontally into the free ends of the two horizontal arms 31 away from the vertical arm 32, that is, fixed to the opposite ends of the two unlocking members 3. When the horizontal arm 31 is pressed and moves in the direction of the grooved wheel 2, during the process of the two unlocking members 3 rotating symmetrically in linkage, the reset member 5 is compressed and stores force in the vertical direction along with the rotation of the unlocking members 3; when the horizontal arm 31 is not under force, the reset member 5 releases the compression and drives the horizontal arm 31 to reset.

[0078] Since the two unlocking components 3 are symmetrically linked, the reset component 5 can achieve a reset effect even if it is only connected to one of the unlocking components 3. Similarly, since the locking component 4 is fixedly connected to the unlocking component 3, the reset component 5 can also be connected to the locking component 4 to provide a reset effect. However, because this embodiment symmetrically arranges the two unlocking components 3, it provides the possibility of selecting one U-shaped spring to simultaneously provide reset force to both unlocking components 3. Therefore, connecting the U-shaped spring to both unlocking components 3 simultaneously allows it to apply the reset force to both unlocking components 3 at the same time, ensuring that the reset force on both sides is equal in magnitude and symmetrical in direction. This forces the two unlocking components 3 to move completely synchronously, avoiding problems such as jamming, uneven wear, and incomplete unlocking / resetting of the locking component 4 due to asynchronous reset. Furthermore, the U-shaped spring is cleverly placed within the limited space between the two unlocking components 3, utilizing the gap naturally generated during the movement of the mechanism, "without occupying additional space."

[0079] Compared to traditional structures with multiple locking components (requiring multiple reset units), which are prone to failure or malfunction due to component failure, and where components like the spring seat and spring work together, the assembly process is more complex and error-prone. In this embodiment, the U-shaped spring requires only a single component, resulting in a simple structure without complex assembly or winding relationships. It is typically formed from a single piece of high-elasticity steel wire, offering high fatigue life and reliability. Therefore, choosing a U-shaped spring reduces the likelihood of failure. The U-shaped spring provides a stable and symmetrical elastic reset force, and its simple structure and high reliability ensure that the locking component 4 can quickly and automatically return to the locked state after disengagement, ensuring safety. Of course, this is not a limitation; other materials or structures with elastic deformation and reset characteristics can also be used, such as bow-shaped spring sheets, bistable (jumping) arch shell structures, shape memory polymers / alloys, etc. Alternatively, a compression spring can be used for each unlocking component 3, with one end fixed to the mounting base 1 and the other end fixed to the unlocking component 3, to achieve reset capability.

[0080] Based on the above description of the structure, it can be understood that the two unlocking components 3, one locking component 4, one resetting component 5, and the grooved wheel 2 (mainly the number of its actuating grooves 21) are designed to work together to achieve the following states and transitions between them:

[0081] The locked state is as follows: the two unlocking parts 311 and the locking part 41 correspond to three different actuation grooves 21 respectively, and the locking part 41 engages with the corresponding actuation groove 21 to lock the grooved wheel 2.

[0082] The unlocking process is as follows: As the mounting base 1 moves with the chain 10, the upper unlocking part 311 of the two unlocking parts 311 is pressed by the pin 6 on the upper side of the travel path of the grooved wheel 2, or in other embodiments or other workstations of this embodiment, the lower unlocking part 311 of the two unlocking parts 311 is pressed by the pin 6 on the lower side of the travel path of the grooved wheel 2. The unlocking member 3 where the pressed unlocking part 311 is located rotates and is linked to the other unlocking member 3 to rotate symmetrically, while driving the locking member 4 to rotate. During the rotation of the locking member 4, the locking part 41 also rotates, causing the locking part 41 to disengage from the actuating groove 21 it is engaged with. At this time, the grooved wheel 2 is unlocked, and the reset member 5 stores force as the unlocking member 3 rotates.

[0083] The locking process is as follows: After the grooved wheel 2 is unlocked, as the mounting base 1 moves with the chain 10, the actuation groove 21 corresponding to the unlocking part 311 pressed against by the actuation pin 6 is pushed by the actuation pin 6, thereby driving the grooved wheel 2 to rotate. When the outer circumference of the grooved wheel 2 moves along the locking part 41 to the next actuation groove 21 aligned with the locking part 41, the stored force of the reset member 5 drives the unlocking member 3 to rotate, thereby driving the locking part 41 to rotate. During the rotation of the locking member 4, the locking part 41 also rotates, causing it to lock with the actuation groove 21. That is, the locking part 41 automatically resets to lock with the actuation groove 21 under the drive of the reset member 5. During this process, the stored force of the reset member 5 also drives the unlocking part 311 to automatically reset to the next actuation groove 21 aligned with the original corresponding actuation groove 21.

[0084] In the locked state, the two unlocking parts 311 and the locking part 41 correspond to three different actuation slots 21. This determines that the positions of the two unlocking parts 311 and the locking part 41 are basically the angle of the adjacent actuation slots 21 or a multiple of that angle. Since the pin 6 must first press the unlocking part 311 to a sufficient unlocking stroke, the position of the unlocking part 311 will be slightly closer to the direction the pin 6 approaches relative to the actuation slot 21. In this embodiment, each actuation slot 21 on the grooved wheel 2 may correspond to the unlocking part 311 in one locked state and engage with the locking part 41 in another locked state. In other words, the actuation slot 21 on the grooved wheel 2 has the dual function of cooperating with the pin 6 to push the grooved wheel 2 to rotate and acting as a locking slot 22 to engage with the locking part 41 to lock the grooved wheel 2, reducing the impact of manufacturing errors.

[0085] The working process of this rotating component is briefly described below:

[0086] Reference Figure 6 and Figure 7When the mounting plate 1 carrying the hand mold rod 20 moves forward with the chain 10 to the position where the hand mold rod 20 needs to rotate (such as adjusting a specific glue insertion angle before glue impregnation or flipping after glue impregnation), as the grooved wheel 2 advances, the first upper pin 6 contacts and presses the unlocking part 311 of the upper unlocking member 3, i.e., the trapezoidal protrusion (of course, in other positions not shown in the figure, the lower pin 6 may contact and press the unlocking part 311 of the lower unlocking member 3). The pressing of the first pin 6 causes the horizontal arm 31 of the unlocking member 3 to swing towards the grooved wheel 2. Through the linkage of the cylindrical pin 33, the two vertical arms 32 move synchronously away from the grooved wheel 2. Then, the locking member 4 connected to the vertical arm 32 moves synchronously with the vertical arm 32, and its locking part 41 exits from the actuation groove 21 of the grooved wheel 2. The grooved wheel 2 is unlocked, and the reset member 5 (U-shaped spring) is in a charged state (the U-shaped spring is compressed) corresponding to the unlocked state of the locking member 4. Then, the first pin 6 enters the actuation slot 21 of the grooved wheel 2 and actuates it, causing the grooved wheel 2 and the hand mold rod 20 on it to rotate by a specific angle (45 degrees in this embodiment). As the mounting plate 1 continues to move forward, the first pin 6 will disengage from the previous actuation slot 21 and gradually disengage from the unlocking part 311. The storage drive of the reset member 5 (U-shaped spring) (i.e., under the action of the elastic rebound force of the U-shaped spring) resets the horizontal arm 31, driving the vertical arm 32 and the locking member 4 to move in the opposite direction. The locking part 41 of the locking member 4 re-embeds into its current corresponding actuation slot 21 (i.e., the next actuation slot 21 of the initial actuation slot 21), firmly locking the grooved wheel 2 and the hand mold rod 20 in a new angular position until the second pin 6 on the upper side is reached. The actuation process of the second pin 6 and the third pin 6 is the same as above and will not be described again. After three actuations, the grooved wheel 2 rotates 135°.

[0087] The required rotation angle of the hand mold rod is determined by the number of pins 6 and the number of actuation slots 21 on the grooved wheel 2. The distance between adjacent pins 6 is mainly related to the moving speed of the chain 10. The minimum distance between adjacent pins 6 should ensure that the grooved wheel 2 has completed one locking-unlocking-locking-locking process between two actuations. Based on the above guarantee, the smaller the distance between adjacent pins 6, the more space is saved.

[0088] The rotating assembly shown in this embodiment uses a locking member 4 that is in a non-rotating state relative to the grooved wheel 2. This locking member directly engages with the actuation groove 21 of the grooved wheel 2 to lock the wheel 2. This effectively solves the problems of uneven load distribution caused by multiple locking members, inaccurate locking positions of some locking members due to individual parts and assembly errors, the need for large assembly gaps, and the impact on locking accuracy. The design gap between the locking member 4 and the actuation groove 21 in this rotating assembly can be set very small, so that the wheel 2 can be completely mechanically locked when it is not rotating. This ensures locking accuracy and effectively prevents accidental rotation of the hand mold rod 20 due to chain 10 vibration or vibration during production. The locking is reliable and can effectively prevent accidental rotation, ensuring the positioning accuracy of the glove in each process.

[0089] Furthermore, by utilizing the movement of the production line itself, automatic unlocking is achieved through cooperation with the pins 6 fixed to the frame. This rapid and reliable operation requires no additional power source or control, allowing for better adaptation to high-speed, continuous production cycles. Its symmetrical drive mechanism design (two linked unlocking components 3) allows trigger points (pins 6) to be positioned from both sides of the production line, simultaneously enabling clockwise and counterclockwise rotation of the grooved wheel 2, providing greater flexibility for the production line's layout. Combined with the L-shaped crank arm linkage mechanism, the synchronous movement of the upper and lower drive points ensures accurate locking and unlocking of the locking component 4. Its built-in elastic reset component 5 ensures that the mechanism automatically returns to the locked state immediately upon disengagement from the drive point, improving equipment safety. The entire device is compact, easy to use, and suitable for various glove production lines, offering a wide range of applications.

[0090] Example 2:

[0091] Reference Figure 8 The glove production line proposed in this embodiment differs from that in Embodiment 1 in that the structure in which the two unlocking parts 3 are linked together at their proximal ends is different. All other parts are the same as in Embodiment 1, and will not be described again here.

[0092] Specifically, meshing teeth 322 are provided at the near ends of the two unlocking members 3 to form a linkage between the two unlocking members 3. That is, at the position where the two vertical arms 32 meet, there are several meshing teeth 32. The teeth 32 are distributed along the contact surface of the vertical arms 32 to form a meshing surface similar to a gear rack. When either vertical arm 32 moves towards or away from the grooved wheel 2, it can drive the other vertical arm 32 to move synchronously through the meshing action of the teeth 32.

[0093] In this embodiment, the two unlocking components 3 are linked by the engagement of the convex teeth 32, resulting in more precise synchronization. This almost completely eliminates the phase difference in the movement of the two vertical arms 32, ensuring absolute synchronization of the upper and lower locking actions and further improving the accuracy and reliability of the locking. Simultaneously, the convex tooth engagement structure itself has a certain degree of self-locking, better resisting minor external interference in the non-drive state and preventing malfunctions. Furthermore, the rigid engagement method results in less wear, a longer service life, and eliminates the need for additional components like the cylindrical pin 33.

[0094] Example 3

[0095] Reference Figure 9 The glove production line proposed in this embodiment differs from that in embodiment 1 in that the structure in which the two unlocking parts 3 are linked together is not located at the adjacent ends of the two unlocking parts 3, but rather the horizontal arm 31 of one unlocking part 3 and the vertical arm 32 of the other unlocking part 3 are linked together.

[0096] Specifically, a connecting rod 36 is located between the mounting base 1 and the grooved wheel 2. Both ends of the connecting rod 36 are hinged to the horizontal arm 31 of one unlocking component 3 and the vertical arm 32 of the other unlocking component 3, respectively. The proximal ends of the two unlocking components 3 are separated from each other with a certain gap to prevent motion interference when the two unlocking components 3 rotate around their corners. Through the connection position of the connecting rod 36 with the two unlocking components 3 and the hinged connection of the two unlocking components 3 to the mounting base 1 at their corners, the two unlocking components 3 can rotate symmetrically.

[0097] Of course, by combining Examples 1-3, it can be seen that the selection and placement of the U-shaped spring are suitable for three different structures in which two unlocking parts 3 are linked together, which also reflects the ingenuity of the selection of the U-shaped spring.

[0098] Example 4

[0099] Reference Figure 10 The glove production line proposed in this embodiment differs from that in Embodiment 1 in that the reset component 5 is a compression spring.

[0100] Specifically, the compression spring is located between the mounting base 1 and the grooved wheel 2, with its two ends connected to the horizontal arms 31 of the two unlocking components 3, and located between the vertical arms 32 of the two unlocking components 3 and the fixed shaft 11 of the grooved wheel 2. To ensure stable compression and reset of the compression spring, a limiting structure for the compression spring can be provided on the mounting base 1, limiting it to moving only in the direction in which the two unlocking components 3 approach each other.

[0101] Of course, the present invention is not limited thereto; in other embodiments, it may be based on... Figure 10The structure extends the horizontal arm 31 of the unlocking component 3 away from the vertical arm 32, so that the compression spring is located on the side of the fixed shaft 11 away from the vertical arm 32. However, this can be understood as the extended part of the horizontal arm 31 being independently connected to the horizontal arm 31 for mounting the compression spring, and the position of the unlocking part at the end of the horizontal arm 31 away from the vertical arm 32 remains unchanged. Figure 10 The position remains unchanged.

[0102] Of course, by combining Examples 1-3, it can be seen that Figure 10 The selection and placement of the compression spring shown are preferably applicable to the structure in Embodiments 1 and 2 where the two unlocking components 3 are linked together. The way in which the compression spring is located on the side of the fixed shaft 11 away from the vertical arm 32 is applicable to the structure in Embodiments 1-3 where the two unlocking components 3 are linked together.

[0103] Example 5

[0104] Reference Figure 11 This embodiment of the glove production line differs from Embodiment 1 in that the number of actuating grooves 21 is four in this embodiment, meaning the included angle between the center lines of adjacent actuating grooves 21 is 90°, and the interval angle between adjacent actuating grooves 21 on the actuating groove 2 is also 90°. In this case, the actuating groove 21 cannot simultaneously function as a drive pin 6 to rotate the grooved wheel 2 and as a locking groove 22 engaging with the locking part 41 to lock the grooved wheel 2. To further enable the rotating assembly to be used for forward and reverse rotation driven by the upper and lower pins and to overcome the problems of the prior art, four actuating grooves 21 and four locking grooves 22 are arranged at equal intervals on the outer peripheral wall of the grooved wheel 2, with the included angle between the center lines of adjacent locking grooves 22 being 90°.

[0105] The two unlocking components 3, the locking component 4, the reset component 5, and the grooved wheel 2 are designed to work together to achieve the following states and transitions between them:

[0106] The locked state is as follows: the two unlocking parts 311 correspond to two different actuation grooves 21 respectively, and the locking part 41 engages with a locking groove 22 facing the direction of approach of the pin 6 to form a lock on the grooved wheel 2;

[0107] The unlocking process is as follows: During the movement of the mounting base 1 with the chain 10, one of the unlocking parts 311 is pressed by the pin 6 on the upper side of the travel path of the grooved wheel 2, or in other embodiments or other workstations of this embodiment, the lower unlocking part 311 of the two unlocking parts 311 is pressed by the pin 6 on the lower side of the travel path of the grooved wheel 2. The unlocking part 3 where the unlocking part 311 is located rotates and is linked to the other unlocking part 3 to rotate symmetrically, while driving the locking part 4 to rotate. The locking part 41 on it also rotates, causing the locking part 41 to disengage from the locking groove 22 it is engaged. At this time, the grooved wheel 2 is unlocked, and the reset part 5 stores force as the unlocking part 3 rotates.

[0108] The locking process is as follows: After the grooved wheel 2 is unlocked, as the mounting base 1 moves with the chain 10, the actuating groove 21 corresponding to the unlocking part 311 pressed against by the actuating pin 6 is pushed by the actuating pin 6, thereby driving the grooved wheel 2 to rotate. When the outer circumference of the grooved wheel 2 moves along the locking part 41 to the next locking groove 22 aligned with the locking part 41, the locking part 41 automatically resets to lock with the locking groove 22 under the drive of the reset member 5. During this process, the stored force of the reset member 5 also drives the unlocking part 311 to automatically reset to the next actuating groove 21 aligned with the original corresponding actuating groove 21. Since the reset member 5 is connected to two unlocking parts 311 in this embodiment, the stored force of the reset member 5 directly drives the unlocking part 311 to automatically reset, and the unlocking part 311 drives the locking part 41 to reset. That is, the reset of the locking part 41 by the reset member 5 is an indirect action. Of course, in other embodiments, such as when the reset member 5 is directly connected to the locking member 41, the reset drive of the reset member 5 on the locking part 41 is a direct drive, and the reset drive of the reset member 5 on the unlocking part 311 is an indirect drive through the locking member 41 driving the unlocking member 3.

[0109] The positions of the actuating groove 21 and the locking groove 22 are matched with the positions of the unlocking part 311 and the locking part 41, and can be adapted by referring to Embodiment 1. The shape of the locking groove 22 is adapted to the shape of the locking part 41, and its depth is smaller than that of the actuating groove 21.

[0110] It is understood that, compared with the prior art, both Embodiments 1 and 5 share the following common feature: the actuating groove 21 / locking groove 22 that cooperates with the locking part 41 to lock the grooved wheel 2 are slots on the outer peripheral wall of the grooved wheel 2, and the number of slots is even, greater than or equal to 6 and less than or equal to 20. In the locked state, the two unlocking parts 311 and the locking part 41 correspond to three different slots on the outer periphery of the grooved wheel 2, respectively. During the unlocking process, the actuating pin 6 also actuates the slots on the outer periphery of the grooved wheel 2.

[0111] In Embodiment 5, the slot simultaneously includes a toggle slot 21 for actuation (not locking) and a locking slot 22 for locking (not actuation). The initial intention is to solve the problem that four equally spaced toggle slots 21 cannot achieve locking. In Embodiments 1-4, the slot includes six equally spaced toggle slots 21 that simultaneously function as both locks and actuates. When the toggle slot 21 can also function as a lock, it is preferable not to separately provide a locking slot 22 to cooperate with the locking member 4. However, when there are fewer toggle slots 21 (especially six), providing the same number of independent locking slots 22 as the toggle slots 21 can also achieve the original inventive purpose of this invention and has little impact on the overall structure, and is also within the scope of protection of this invention.

[0112] Example 6

[0113] Reference Figure 12 and Figure 13The glove production line proposed in this embodiment differs from that in Embodiment 1 in that the connection method between the pin 6 and the pin plate 9 is different. All other parts are the same as in Embodiment 1, and will not be described in detail here.

[0114] In Embodiment 1, the pin 6 is fixedly connected to the pin plate 9. In this embodiment, the pin 6 is rotatably connected to the pin plate 9 between a shifting position and a yielding position, and it has a free end that can swing towards the pulley 2 when the chain 10 moves forward. Specifically, the pin 6 has a stop 7 fixed to the pin plate 9 on the side facing away from the pulley 2 when the chain 10 moves forward, to restrict the pin 6 from being stopped in the shifting position when the chain 10 moves forward. The unlocking part 311 can be pressed, and the pin 6 can only be rotated to the yielding position by the unlocking part 311 when the chain 10 moves in the reverse direction. During this process, the pulley 2 remains locked.

[0115] In this embodiment, the pin 6 is rotatably connected to the pin plate 9 via a lever 8. The pin plate 9 is detachably fixed to the frame. The pin plate 9 is provided only to facilitate the detachable connection between the pin 6 and the frame, and to improve the compatibility between the components. Therefore, it can be understood that the lever 8 is essentially rotatably connected to the frame. The lever 8 has a rotating end 81 and a swinging end 82. The rotating end 81 is pivotally connected to the pin plate 9 (i.e., pivotally connected to the frame). The pin 6 is fixed to the swinging end 82. Here, "fixed" means that the movement between the pin 6 and the swinging end 82 is synchronized, not that the connection is non-detachable. The pin 6 can also be detachably inserted into the swinging end 82. In this embodiment, the width of the swing end 82 is greater than the width of the derailleur 6. Consequently, the stop 7 abuts against the side wall of the swing end 82 facing away from the pulley 2 when the chain moves forward. In other embodiments, the stop 7 may also abut against the side wall of the derailleur 6 facing away from the pulley 2 when the chain 10 moves forward. The stop 7 may be a block / pin fixed to the derailleur plate 9 (i.e., fixed to the frame) or a protrusion extending from the derailleur plate 9 itself.

[0116] Under normal circumstances, the mounting base 1 moves forward with the chain 10, the unlocking part 311 abuts against the free end of the pin 6 located in the shifting position, and the stop 7 forms a stop on the pin 6, causing the pin 6 to press against the unlocking part 311, thereby unlocking and shifting the grooved wheel 2. When a "reverse" requirement occurs, the drive chain 10 moves in the reverse direction, the chain 10 drives the mounting plate 1 to move in the reverse direction relative to the frame, and the unlocking part 311 pushes the free end of the pin 6 to rotate to the yielding position until the unlocking part 311 separates from the pin 6. This configuration allows "reverse" to be achieved directly by adjusting the direction of movement of the chain 10 (i.e., by driving the hand lever 20 to move in the reverse direction via the mounting plate 1) when a "reverse" requirement occurs on the production line. During this process, the pin 6 will not interfere with moving parts such as the grooved wheel 2. Therefore, a seamless connection between reversing and the entire automation system can be achieved, without the need for additional time to adjust or disassemble the pin 6 / pin plate 9, effectively improving production efficiency.

[0117] During the operation of a glove production line, there are various situations requiring "reversing." For example, when a glove mold is damaged, stuck together, or misaligned at stations such as dipping or hemming, the mold rod 20 may need to be briefly reversed back to the previous station for repair or cleaning to avoid affecting subsequent processes. Alternatively, if the coating thickness is found to be substandard after the dipping tank, it may need to be reversed for re-dipping. Furthermore, if a quality inspector discovers an anomaly at a specific station (such as after hemming), adjacent molds may need to be reversed for manual review. Reversing is also necessary to alleviate congestion due to temporary speed mismatches between stations (such as congestion at the demolding station). Therefore, the reversing function is crucial in the glove production line, improving fault response speed, reducing scrap rates, and supporting flexible production scheduling.

[0118] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0119] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions and variations to the above embodiments within the scope of the present invention.
