[0003] The existing automatic demoulding equipment for PVC gloves moves the pre-demolding PVC gloves on the hand mold together with the hand mold between the manipulators, and the movement of the manipulators makes the manipulators fit the surface of the hand mold. At this time, the cuffs of the PVC gloves are turned out and fixed on the manipulators through the brush device on the manipulators. At this time, the hand mold and the manipulators move synchronously, and the manipulators slide in the guide rails and move away from the hand mold to separate the PVC gloves from the hand mold for subsequent glove quality inspection.

[0004] There are still some problems in the actual use of the existing automatic demoulding equipment for PVC gloves. When the existing automatic demoulding equipment for PVC gloves is used, when a robot is used to demould the PVC gloves on the hand mold, the material on some PVC gloves is unevenly distributed during formation, resulting in some areas being too thin. When demoulding them, the too thin areas are damaged by lateral tension during demoulding due to insufficient strength, resulting in the PVC gloves breaking, and some PVC gloves are still attached to the hand mold. As the hand mold is used again, the PVC gloves formed on the hand mold cover the remaining PVC glove fragments on the hand mold, resulting in inconsistent appearance of the formed PVC gloves, resulting in a reduced product yield.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0037] like Figures 1 to 11As shown, an automatic demoulding device for PVC gloves according to an embodiment of the present invention comprises a base plate 1, support rods 11 are fixedly connected near the corners on both sides of the base plate 1, a rotating shaft 12 is rotatably connected to the top of each support rod 11, a sprocket 13 is fixedly connected to one end of each rotating shaft 12 away from the support rod 11, a chain 14 is drivingly connected between the two sprockets 13 at both ends of the base plate 1, a support column 15 is rotatably arranged between the two sprockets 13 on the same side of the base plate 1, two mutually parallel guide rails 16 are fixedly connected between the two support columns 15, a plurality of limiting rods 17 are fixedly connected between the two chains 14, and the plurality of limiting rods 17 are arranged parallel to each other, a displacement block 18 is slidably connected between the two guide rails 16, and the limiting rod 17 passes through the displacement block 18, a cleaning component is arranged on the displacement block 18, and the cleaning component is used to clean the residual part of the PVC gloves on the hand mold, and a manipulator 19 is symmetrically arranged on the displacement block 18.

[0038] Specifically, when the existing automatic demoulding equipment for PVC gloves is used, when the robot 19 is used to demould the PVC gloves on the hand mold, the material on some PVC gloves is unevenly distributed during molding, resulting in some areas being too thin. When demoulding them, the too thin areas are damaged by lateral tension during demoulding due to insufficient strength, resulting in the PVC gloves breaking, and some PVC gloves are still attached to the hand mold. As the hand mold is used again, the PVC gloves formed on the hand mold cover the remaining PVC glove fragments on the hand mold, resulting in inconsistent appearance of the formed PVC gloves, resulting in a reduced product yield.

[0039] Therefore, the present invention solves this problem by setting a corresponding structure. After the PVC glove is molded on the hand mold, the hand mold with the PVC glove is transported by a conveying device. When the hand mold is located above the displacement block 18, the manipulator 19 is contracted to clamp the wrist of the PVC glove on the hand mold. In this process, the sprocket 13 on the rotating shaft 12 rotates along with the rotating shaft 12 through the rotation of the rotating shaft 12. Since the sprocket 13 is rotationally connected to the support column 15, the support column 15 remains stationary when the sprocket 13 rotates, thereby providing support for the guide track 16 on the support column 15. The rotation of the sprocket 13 causes the chain 14 on it to rotate synchronously, thereby causing the limit rod 17 between the chain 14 to move along with the displacement of the chain 14. Since the limit rod 17 passes through the displacement block 18 and the displacement block 1 8 slides between the guide rails 16, so that the displacement block 18 is limited under the joint action of the guide rails 16 and the limiting rod 17, and slides between the guide rails 16 with the displacement of the limiting rod 17, so that the displacement block 18 and the hand mold are at the same moving speed, ensuring that the hand mold and the displacement block 18 are in a relatively static state, avoiding the generation of lateral tension when the PVC gloves on the hand mold are removed and tearing the PVC gloves; at the same time, the displacement block 18 is guided by the guide rails 16 and moves in the direction away from the hand mold, thereby driving the manipulator 19 on the displacement block 18 to move together, and driving the manipulator 19 to move downward along the vertical direction of the hand mold to complete the demoulding of the PVC gloves; solving the problem that when demoulding, the too thin area is damaged by the lateral tension during demoulding due to insufficient strength, resulting in the breakage of the PVC gloves;

[0040] During the demoulding process of the PVC gloves on the hand mold, if some PVC gloves are broken and some PVC glove fragments are still attached to the hand mold, the hand mold is cleaned by a cleaning device, so that the hand mold remains clean after the PVC gloves are demoulded, thereby solving the problem that when the hand mold is used again, the PVC gloves formed on the hand mold cover part of the remaining PVC glove fragments on the hand mold, resulting in inconsistent appearance of the formed PVC gloves and reduced product yield.

[0041] like Figures 1 to 3 As shown, in this embodiment, a ratchet mechanism is provided between the sprocket 13 and the support column 15 , the displacement block 18 is slidably connected between the limiting rods 17 , and the displacement block 18 corresponds to the limiting rods 17 one by one.

[0042] Specifically, a ratchet mechanism is provided between the sprocket 13 and the support column 15. The ratchet mechanism can keep the support column 15 stationary when the sprocket 13 rotates, thereby providing support for the guide track 16 on the support column 15; the displacement block 18 and the limit rod 17 correspond one-to-one, and each limit rod 17 has a displacement block 18 sliding on it.

[0043] like Figures 3 to 7 As shown, the cleaning assembly described in this embodiment includes a guide rack rod 21, and the guide rack rod 21 is symmetrically fixedly connected between the limit rods 17. A first transmission groove 22 is opened inside the displacement block 18, and a second transmission groove 23 is opened inside the displacement block 18. A transmission gear 24 is rotatably connected in the first transmission groove 22, and the guide rack rods 21 are meshed with the transmission gear 24. Rotating rods 25 are rotatably connected at both ends of the transmission gear 24.

[0044] Specifically, in the process of the displacement block 18 moving along the guide track 16, due to the curved track path setting of the guide track 16, the displacement block 18 can produce relative displacement with respect to the limit rod 17, and the transmission gear 24 in the first transmission groove 22 moves together with the displacement block 18. Since the transmission gear 24 is engaged with the guide rack rod 21, the transmission gear 24 rotates during the displacement process of the displacement block 18, thereby driving the rotating rod 25 thereon to rotate together with the transmission gear 24 in the first transmission groove 22.

[0045] like Figures 8 to 10 As shown, the cleaning assembly described in this embodiment also includes a ratchet groove 26, and the ratchet groove 26 is opened between the transmission gear 24 and the rotating rod 25. A limiting shaft 27 is fixedly connected in the ratchet groove 26, and a moving plate 28 is rotatably connected to the surface of the limiting shaft 27. A return spring 29 is fixedly connected between the moving plate 28 and the inner wall of the ratchet groove 26.

[0046] Specifically, Fig.10As shown, in the process of demoulding the PVC gloves on the hand mold, when the transmission gear 24 rotates, the inner wall of the ratchet groove 26 in the transmission gear 24 contacts with the moving plate 28, and drives the moving plate 28 to move in the direction away from the return spring 29 with the limit shaft 27 as the axis. At this time, the return spring 29 elastically stretches until the moving plate 28 contacts with the inner wall of the ratchet groove 26 on the rotating rod 25, so that when the transmission gear 24 rotates, the rotating rod 25 rotates with the transmission gear 24; in the process of the displacement block 18 returning to the initial position, the transmission gear 24 moves in the opposite direction, so that the transmission gear 24 rotates in the opposite direction under the action of the guide rack rod 21. At this time, under the action of the return spring 29 and the inner wall of the ratchet groove 26 in the transmission gear 24, the moving plate 28 moves in the direction close to the ratchet groove in the rotating rod 25 with the limit shaft 27 as the axis. 26, during which the return spring 29 first elastically contracts to the initial state, and then is elastically compressed with the displacement of the moving plate 28 until the inner wall of the ratchet groove 26 in the transmission gear 24 passes through the moving plate 28, at which time the moving plate 28 enters the ratchet groove 26 on the transmission gear 24 in the next area, at which time the moving plate 28 returns to the initial position under the action of the elastic release of the return spring 29, and is again squeezed by the inner wall of the ratchet groove 26 in the transmission gear 24 as the transmission gear 24 rotates, and so on, so that when the transmission gear 24 rotates in the opposite direction, the rotating rod 25 remains stationary, and when the displacement block 18 is reset, the rotating rod 25 does not rotate, so that when the cleaning device does not contact the hand mold, there is no need to clean the hand mold, thereby reducing the mechanical wear of the mechanical components in the cleaning device and extending the service life of the cleaning device.

[0047] like Figures 3 to 7 As shown, the cleaning assembly of this embodiment also includes a transmission rod 211, which is rotatably connected to the second transmission groove 23, and a first transmission belt 210 is transmission-connected between the rotating rod 25 and the transmission rod 211, and a support block 214 is symmetrically fixedly connected to the top of the displacement block 18, and a cleaning brush 213 is rotatably connected between the support blocks 214, and a second transmission belt 212 is transmission-connected between the cleaning brush 213 and the transmission rod 211.

[0048] Specifically, when the rotating rod 25 rotates, the rotating rotating rod 25 drives the transmission rod 211 to rotate in the second transmission groove 23 through the transmission of the first transmission belt 210, and then the rotating transmission rod 211 drives the cleaning brush 213 to rotate between the support blocks 214 through the transmission of the second transmission belt 212, and then the surface of the hand mold on the support block 214 is cleaned. In the process of demolding the PVC gloves on the hand mold, some PVC gloves are broken, and some PVC glove fragments are still attached to the hand mold. At this time, the cleaning brush 213 is rotated to clean the remaining PVC glove fragments on the hand mold, so that the remaining PVC glove fragments on the hand mold are rolled together under the rotation of the cleaning brush 213, and then fall off the hand mold, so that the hand mold remains clean after the PVC gloves are demolded, and the problem that the PVC gloves formed on the hand mold cover the remaining PVC glove fragments on the hand mold when the hand mold is used again, so that the appearance of the formed PVC gloves product is inconsistent, resulting in a decrease in the yield rate of the product, thereby improving the yield rate of the product.

[0049] like Figures 4 to 6 As shown, the guide rack rod 21 of this embodiment passes through the displacement block 18 and the displacement block 18 slides on the guide rack rod 21 , and the first transmission groove 22 is connected to the second transmission groove 23 .

[0050] Specifically, the guide rack rod 21 passes through the displacement block 18 and the displacement block 18 slides on the guide rack rod 21, so that the guide rack rod 21 is engaged with the transmission gear 24 in the first transmission groove 22, and then the transmission gear 24 is driven to rotate through the displacement of the displacement block 18. At the same time, the displacement block 18 slides on the guide rack rod 21 to limit the displacement block 18 to only perform horizontal linear motion on the guide rack rod 21; the first transmission groove 22 is connected to the second transmission groove 23, so that when the rotating rod 25 rotates, the transmission rod 211 can be transmitted through the first transmission belt 210, so that the transmission rod 211 rotates together with the rotating rod 25.

[0051] like Fig. 9 and Fig.10 As shown, the shape of the moving plate 28 in this embodiment matches the shape of the ratchet groove 26, and the shape of the ratchet groove 26 on the transmission gear 24 is trapezoidal.

[0052] Specifically, the shape of the moving plate 28 matches the shape of the ratchet groove 26, so that the moving plate 28 can contact with the ratchet groove 26 and slide in the ratchet groove 26; the shape of the ratchet groove 26 on the transmission gear 24 is trapezoidal, so that when the transmission gear 24 rotates in the forward direction, the inner wall of the ratchet groove 26 on the transmission gear 24 contacts the moving plate 28, so that the moving plate 28 contacts the inner wall of the ratchet groove 26 in the rotating rod 25, so that the rotating rod 25 rotates with the transmission gear 24, and at the same time, when the transmission gear 24 rotates in the reverse direction, the inner wall of the ratchet groove 26 in the transmission gear 24 squeezes the moving plate 28 so that the moving plate 28 shrinks in the ratchet groove 26 inside the rotating rod 25, so that the rotating rod 25 is stationary when the transmission gear 24 rotates.

[0053] like Figure 3 and Fig.11 As shown, the cleaning brush 213 of this embodiment is located below the hand mold and contacts the hand mold.

[0054] Specifically, the cleaning brush 213 is located below the hand mold and contacts the hand mold. At this time, the robot 19 clamps the PVC glove on the hand mold and demolds the PVC glove by moving the robot 19. During this process, when the PVC glove is broken, some PVC glove fragments remain on the hand mold and are not taken off. At this time, the cleaning brush 213 rotates and contacts the demolded hand mold to clean the remaining PVC glove fragments on the hand mold. Embodiment 2

[0055] like Figures 2 to 11 As shown, compared with Example 1, another implementation of the present invention is:

[0056] like Figure 2 , Figure 3 and Fig.11 As shown, in this embodiment, a first collection box 31 is fixedly connected to the top of the displacement block 18 , and a second collection box 32 is fixedly connected to one side of the bottom plate 1 .

[0057] Specifically, after the PVC gloves are demoulded, the PVC gloves fragments remaining on the hand mold cleaned by the cleaning brush 213 fall into the first collecting box 31 under the action of gravity. The PVC gloves fragments cleaned by the cleaning brush 213 are collected by the first collecting box 31, so as to prevent the cleaned PVC gloves fragments from falling on the limiting rod 17 or the guide rack rod 21, so as to prevent the displacement block 18 from contacting with the limiting rod 17 or the guide rack rod 21 during the movement and blocking the displacement block 18. The stability of the device operation is ensured, and at the same time, the cleaned PVC gloves fragments are prevented from falling on the bottom plate 1, so as to ensure the cleanliness of the production environment.

[0058] When the displacement block 18 moves to the farthest point, as the sprocket 13 continues to move, under the action of the guide track 16 and the sprocket 13, the displacement block 18 turns and prepares to reset. At this time, the cleaned PVC glove fragments collected in the first collecting box 31 on the displacement block 18 fall into the second collecting box 32 under the action of gravity. The cleaned PVC glove fragments in the first collecting box 31 are collected by the second collecting box 32, which prevents the cleaned PVC glove fragments collected in the first collecting box 31 from falling onto the bottom plate 1 when the first collecting box 31 returns to the initial position as the displacement block 18. This ensures that the first collecting box 31 is tidy when the support block 214 cleans the hand mold again, and the cleaned PVC glove fragments collected in the second collecting box 32 can be reused, thereby reducing the production cost.

[0059] like Fig.11 As shown, in this embodiment, the first collecting box 31 is located below the cleaning brush 213, the bottom of the first collecting box 31 is set as a slope, the second collecting box 32 is located below one end of the guide rail 16, and the first collecting box 31 above the second collecting box 32 is on the same vertical line as the second collecting box 32.

[0060] Specifically, the bottom of the first collecting box 31 is set as a slope. When some of the cleaned PVC gloves fall into the first collecting box 31, they move to the lower part of the slope due to the slope, so that they are better located in the first collecting box 31; the first collecting box 31 above the second collecting box 32 is on the same vertical line as the second collecting box 32, so that when it turns and resets, some of the cleaned PVC gloves collected in the first collecting box 31 fall into the second collecting box 32, ensuring that there is an empty space in the first collecting box 31 after its reset.

[0061] Working principle:

[0062] After the PVC gloves are shaped on the hand mold, the hand mold with the PVC gloves is transported by a conveying device. When the hand mold is located above the displacement block 18, the manipulator 19 contracts to clamp the wrist of the PVC glove on the hand mold. In this process, the sprocket 13 on the rotating shaft 12 rotates along with the rotating shaft 12 through the rotation of the rotating shaft 12. Since the sprocket 13 is rotationally connected to the support column 15, the support column 15 remains stationary when the sprocket 13 rotates, thereby providing support for the guide rail 16 on the support column 15. The rotation of the sprocket 13 causes the chain 14 on it to rotate synchronously, thereby causing the limit rods 17 between the chains 14 to move along with the displacement of the chains 14. 17 penetrates the displacement block 18 and the displacement block 18 slides between the guide rails 16, so that the displacement block 18 is limited under the joint action of the guide rails 16 and the limiting rod 17, and slides between the guide rails 16 driven by the displacement of the limiting rod 17, so that the displacement block 18 and the hand mold are at the same moving speed, ensuring that the hand mold and the displacement block 18 are in a relatively static state, avoiding the generation of lateral tension when the PVC gloves on the hand mold are removed and tearing the PVC gloves; at the same time, the displacement block 18 is guided by the guide rails 16 and moves in the direction away from the hand mold, thereby driving the manipulator 19 on the displacement block 18 to move together, and driving the manipulator 19 to move downward along the vertical direction of the hand mold to complete the demoulding of the PVC gloves;

[0063] In the process of the displacement block 18 moving along the guide track 16, due to the curved track path setting of the guide track 16, the displacement block 18 can produce relative displacement with respect to the limit rod 17, and the transmission gear 24 in the first transmission groove 22 moves together with the displacement block 18. Because the transmission gear 24 is meshed with the guide rack rod 21, the transmission gear 24 rotates during the displacement process of the displacement block 18, thereby driving the rotating rod 25 thereon to rotate together with the transmission gear 24 in the first transmission groove 22. When the transmission gear 24 rotates, the inner wall of the ratchet groove 26 in the transmission gear 24 contacts the moving plate 28, and drives the moving plate 28 to move in the direction away from the return spring 29 with the limit shaft 27 as the axis. At this time, the return spring 29 elastically stretches until the moving plate 28 and the rotating rod 25 are aligned. The ratchet groove 26 on the rod 25 is in contact with the inner wall thereof, so that when the transmission gear 24 rotates, the rotating rod 25 rotates together with the transmission gear 24. When the rotating rod 25 rotates, the rotating rotating rod 25 drives the transmission rod 211 to rotate in the second transmission groove 23 through the transmission of the first transmission belt 210, and then the rotating transmission rod 211 drives the cleaning brush 213 to rotate between the support blocks 214 through the transmission of the second transmission belt 212, and then the surface of the hand mold on the support blocks 214 is cleaned. During the demoulding process of the PVC gloves, some of the PVC gloves are broken, and some of the PVC glove fragments are still attached to the hand mold. At this time, the cleaning brush 213 is rotated to clean the remaining PVC glove fragments on the hand mold, so that the hand mold remains clean after the PVC gloves are demoulded;

[0064] After the cleaning brush 213 cleans the remaining PVC glove fragments on the hand model, the remaining PVC glove fragments on the hand model cleaned by the cleaning brush 213 fall into the first collection box 31 under the action of gravity, and the PVC glove fragments cleaned by the cleaning brush 213 are collected by the first collection box 31. When the displacement block 18 moves to the farthest point, as the sprocket 13 continues to move, under the action of the guide track 16 and the sprocket 13, the displacement block 18 turns and prepares to reset. At this time, the PVC glove fragments collected in the first collection box 31 on the displacement block 18 fall into the second collection box 32 under the action of gravity;

[0065] When the displacement block 18 returns to its initial position, the transmission gear 24 moves in the opposite direction, causing the transmission gear 24 to rotate in the opposite direction under the action of the guide rack rod 21. At this time, under the action of the return spring 29 and the inner wall of the ratchet groove 26 in the transmission gear 24, the moving plate 28 moves with the limit shaft 27 as the axis toward the bottom of the ratchet groove 26 in the rotating rod 25. In this process, the return spring 29 first elastically contracts to the initial state, and then is elastically compressed with the displacement of the moving plate 28 until the inner wall of the ratchet groove 26 in the transmission gear 24 passes through the moving plate 28. At this time, the moving plate 28 enters the ratchet groove 26 on the transmission gear 24 in the next area. At this time, the moving plate 28 returns to its initial position under the action of the elastic release of the return spring 29, and is squeezed by the inner wall of the ratchet groove 26 in the transmission gear 24 again as the transmission gear 24 rotates, and so on. When the transmission gear 24 rotates in the opposite direction, the rotating rod 25 remains stationary, so that the rotating rod 25 does not rotate when the displacement block 18 is reset until the displacement block 18 returns to its initial position.

When the hand model is displaced to the top of the displacement block (18) above the support column (15), the displacement block (18) is specifically located above the guide track (16) in the middle of the support column (15). At this time, the mechanical hand (19) contracts to clamp the wrist of the PVC glove on the hand model. In this process, the sprocket (13) on the rotating shaft (12) rotates along with the rotating shaft (12) through the rotation of the rotating shaft (12). Since the sprocket (13) is rotatably connected to the support column (15), the support column (15) remains stationary when the sprocket (13) rotates, thereby providing support for the guide track (16) on the support column (15). The rotation of the sprocket (13) causes the sprocket (13) on the support column (15) to rotate. The chains (14) rotate synchronously, thereby causing the limiting rods (17) between the chains (14) to move together with the displacement of the chains (14). Since the limiting rods (17) penetrate the displacement blocks (18) and the displacement blocks (18) slide between the guide rails (16), the displacement blocks (18) are limited under the joint action of the guide rails (16) and the limiting rods (17), and slide between the guide rails (16) driven by the displacement of the limiting rods (17), so that the displacement blocks (18) and the hand mold are at the same moving speed. At the same time, the displacement blocks (18) are displaced in a direction away from the hand mold under the guidance of the guide rails (16), thereby driving the manipulator (19) on the displacement blocks (18) to move together, and driving the manipulator (19) to move downward along the vertical direction of the hand mold, thereby completing the demoulding of the PVC gloves; During the movement of the displacement block (18) along the guide track (16), the displacement block (18) can generate relative displacement relative to the limit rod (17) due to the curved track path setting of the guide track (16). The transmission gear (24) in the first transmission groove (22) moves together with the displacement block (18). Since the transmission gear (24) is meshed with the guide rack rod (21), the transmission gear (24) rotates during the displacement of the displacement block (18), thereby driving the rotating rod (25) thereon to rotate together with the transmission gear (24) in the first transmission groove (22). When the transmission gear (24) rotates, the inner wall of the ratchet groove (26) in the transmission gear (24) contacts the moving plate (28), and drives the moving plate (28) to rotate. 28) is displaced in a direction away from the return spring (29) with the limit shaft (27) as the axis, and the return spring (29) is elastically stretched until the moving plate (28) contacts the inner wall of the ratchet groove (26) on the rotating rod (25), so that when the transmission gear (24) rotates, the rotating rod (25) rotates along with the transmission gear (24). When the rotating rod (25) rotates, the rotating rotating rod (25) drives the transmission rod (211) to rotate in the second transmission groove (23) through the transmission of the first transmission belt (210), and then the rotating transmission rod (211) drives the cleaning brush (213) to rotate between the support blocks (214) through the transmission of the second transmission belt (212), thereby cleaning the surface of the hand mold on the support block (214); After the cleaning brush (213) cleans the remaining PVC glove fragments on the hand model, the remaining PVC glove fragments on the hand model cleaned by the cleaning brush (213) fall into the first collection box (31) under the action of gravity, and the PVC glove fragments cleaned by the cleaning brush (213) are collected by the first collection box (31). When the displacement block (18) moves to the farthest point, as the sprocket (13) continues to move, under the action of the guide track (16) and the sprocket (13), the displacement block (18) turns and prepares to reset. At this time, the PVC glove fragments collected in the first collection box (31) on the displacement block (18) fall into the second collection box (32) under the action of gravity; When the displacement block (18) returns to the initial position, the transmission gear (24) moves in the opposite direction, so that the transmission gear (24) rotates in the opposite direction under the action of the guide rack rod (21). At this time, under the action of the return spring (29) and the inner wall of the ratchet groove (26) in the transmission gear (24), the moving plate (28) moves with the limit shaft (27) as the axis toward the bottom of the ratchet groove (26) in the rotating rod (25). In this process, the return spring (29) first elastically contracts to the initial state, and then is elastically compressed as the moving plate (28) is displaced until the transmission gear (24) is in the direction of the bottom of the ratchet groove (26) in the rotating rod (25). The inner wall of the ratchet groove (26) passes through the moving plate (28), and the moving plate (28) enters the ratchet groove (26) on the transmission gear (24) of the next area. At this time, the moving plate (28) returns to the initial position under the elastic release of the return spring (29), and is squeezed by the inner wall of the ratchet groove (26) in the transmission gear (24) again as the transmission gear (24) rotates, and this reciprocating process makes the rotating rod (25) remain stationary when the transmission gear (24) rotates in the reverse direction, so that the rotating rod (25) does not rotate when the displacement block (18) is reset, until the displacement block (18) returns to the initial position.
