Description

Technical Field

[0001] This invention relates to the technical field of glove machines, and in particular to a glove cuff expansion mechanism. Background Technology

[0002] Glove turning machines commonly employ various forms, including front and back hand operation, convex and concave operation, and foot-operated models. Manually turning gloves is slow and requires high levels of physical exertion from the operator. With societal development and increased automation, customer demands for glove turning machines are also rising. To meet market and customer needs, different manufacturers are continuously researching and improving various glove turning machines according to their own approaches, aiming to enhance production efficiency and automation levels.

[0003] Based on this, this application is filed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and provide a glove cuff expansion mechanism that can simultaneously drive two mechanical claw devices to grasp the sides of the glove cuff and expand the glove cuff, facilitating the smooth automatic turning of the glove inside out.

[0005] To achieve the above objectives, the present invention proposes a glove cuff expansion mechanism, comprising a guide plate, a limiting and fixing plate, a stretching mechanism and a driving mechanism, wherein the guide plate is connected to the limiting and fixing plate;

[0006] The stretching mechanism is divided into a left stretching mechanism and a right stretching mechanism that can be opened and closed and clamp the two sides of the glove opening. The left stretching mechanism and the right stretching mechanism are symmetrically arranged on the left and right sides along the drive mechanism. The drive mechanism drives the left stretching mechanism and the right stretching mechanism to move in opposite directions or relative to each other.

[0007] Both the left and right stretching mechanisms include a limiting block connected to the lower part of the limiting fixing plate and a mechanical claw device. The limiting block has a straight track and an inclined track connected on both sides, and the two inclined tracks are distributed in a gradually converging shape.

[0008] The mechanical gripper device includes a left mechanical gripper device and a right mechanical gripper device. Both the left and right mechanical gripper devices are provided with a front gripper, a rear gripper, and a connecting seat. The front gripper and the rear gripper are rotatably fixed to the connecting seat by an upper shaft screw. The limiting block includes a left limiting block and a right limiting block.

[0009] Initially, the left and right mechanical claw devices are positioned on the inclined tracks of the left and right limit blocks, respectively, with their corresponding front and rear claws in the open state.

[0010] When the left and right stretching mechanisms generate opposite movements, the left and right mechanical claw devices move along the inclined tracks of the left and right limit blocks respectively, and the front and rear claws also slowly retract. Then, the left and right mechanical claw devices exit the inclined tracks of the left and right limit blocks respectively and enter the straight tracks of the left and right limit blocks. At the same time, the front and rear claws on both sides of the glove opening clamp the glove opening sides respectively.

[0011] The drive mechanism is connected to the connecting seat and drives it to move in opposite directions or relative to the limiting block. The front and rear claws are provided with lower shaft screws that are pulled together by tension springs. The tension springs pull the lower shaft screws to keep them in contact with the straight or inclined track. The lower shaft screws follow the connecting seat and slide back and forth along the straight and inclined tracks to complete the opening and closing action of the front and rear claws to clamp the cuff side of the glove.

[0012] The drive mechanism includes a left drive block and a right drive block, as well as a transmission device driven by the drive device to rotate. The left and right drive blocks are symmetrically connected to both sides of the synchronous belt of the transmission device. Reversing the synchronous belt causes the left and right tensioning mechanisms mounted on the left and right drive blocks to move in opposite directions or relative to each other.

[0013] Preferably, the upper axle screw includes an upper front axle screw and an upper rear axle screw, with the front and rear pawls rotating along the upper front and upper rear axle screws respectively. The lower axle screw includes a lower front axle screw and a lower rear axle screw, which are connected to the front and rear pawls after passing through the lower bearing.

[0014] Preferably, the lower bearing includes a lower front bearing and a lower rear bearing, with a tension spring disposed between the lower front axle screw and the lower rear axle screw, and the lower front bearing and the lower rear bearing disposed on the straight track or inclined track of the limiting block.

[0015] Preferably, the left and right transmission blocks have slots on their sides, and the bottom of the slots has closed slots. The top block is placed in the closed slot of the transmission block, and the toothed part of the top block cooperates with the toothed part of the synchronous belt in the transmission device, and is combined with the pressure plate to press the synchronous belt.

[0016] Preferably, the left and right transmission blocks are provided with left and right slots on their sides, respectively, and the top block includes a left top block and a right top block, which are respectively located at the bottom of the left and right slots.

[0017] Preferably, the transmission device includes a main synchronous pulley and a driven synchronous pulley rotatably mounted on the guide rail base, and a synchronous belt tensioned on the main synchronous pulley and the driven synchronous pulley, and the drive device is fixed on the guide rail base and drivenly connected to the main synchronous pulley.

[0018] Preferably, the drive device includes a housing and a worm gear assembly, with the drive motor located on the right side of the housing. Its drive shaft is connected to the worm gear assembly, one end of the main drive shaft is connected to the worm gear assembly, and the other end is connected to the main synchronous pulley.

[0019] Preferably, the other end of the main drive shaft is connected to the main synchronous pulley after passing through the guide rail seat, the pad is disposed on the right side of the guide rail seat, and the driven shaft is disposed between the driven synchronous pulley and the pad.

[0020] Preferably, the guide rail base is flexibly provided with a left sliding column and a right sliding column, and the left transmission block and the right transmission block are respectively connected to the left sliding column and the right sliding column.

[0021] The beneficial effects of this invention are:

[0022] 1. The stretching mechanism adopts a structure that combines a limit block with a mechanical claw device. The drive mechanism controls the lower shaft screw of the two sets of mechanical claw devices to move along the straight or inclined track of the limit block. With the help of the tension spring, the opening and closing of the front claw and the rear claw are completed, so as to grasp the two sides of the glove opening.

[0023] 2. The drive mechanism uses symmetrical left and right transmission blocks to connect the mechanical claw devices. The synchronous belt drives the two mechanical claw devices to move relative to or away from each other. Combined with the gripping action of the glove cuff, the glove cuff is stretched and contracted.

[0024] 3. In this invention, a single drive mechanism simultaneously drives the movement of the left and right stretching mechanisms. During the movement of the mechanical claw devices in the left and right stretching mechanisms, not only is the glove cuff grasped, but the stroke control between the mechanical claw devices after grasping is also completed to achieve the purpose of cuff expansion, thereby improving the automation level of the product.

[0041] See Figures 1 to 5 The present invention includes a guide plate 1, a limiting and fixing plate 2, a tensioning mechanism 3 and a driving mechanism 4. The guide plate 1 is connected to the limiting and fixing plate 2, and the limiting and fixing plate 2 is located below the guide plate 1.

[0042] The stretching mechanism 3 is divided into a left stretching mechanism 3A and a right stretching mechanism 3B, which can open and close and clamp both sides of the glove opening. The left stretching mechanism 3A is used to clamp the left side of the glove opening, and the right stretching mechanism 3B is used to clamp the right side of the glove opening. The left stretching mechanism 3A and the right stretching mechanism 3B are symmetrically arranged on the left and right sides along the drive mechanism 4. The drive mechanism 4 drives the left stretching mechanism 3A and the right stretching mechanism 3B to move in opposite directions or relative to each other, so as to clamp and expand the glove opening.

[0043] Both the left stretching mechanism 3A and the right stretching mechanism 3B include a limiting block 31 connected below the limiting fixing plate 2 and a mechanical claw device 330. The limiting block 31 has a straight track 31A and an inclined track 31B connected on both sides. The two inclined tracks 31B are distributed in a gradually converging manner, and the straight tracks 31A on both sides are distributed in a parallel manner.

[0044] The mechanical gripper device 330 includes a left mechanical gripper device 330A and a right mechanical gripper device 330B.

The tension spring 35 pulls the lower shaft screws to keep them in contact with the straight track 31A or the inclined track 31B. When the drive mechanism 4 drives the connecting seat 39 to move, the lower shaft screws follow the connecting seat 39 to slide back and forth along the straight track 31A and the inclined track 31B to complete the opening and closing action of the front claw 36 and the rear claw 38 to clamp the cuff side of the glove.

[0046] The drive mechanism 4 includes a transmission device 47 driven by a drive unit to rotate and transmission blocks symmetrically arranged on the left and right sides of the transmission device 47. The transmission blocks are divided into a left transmission block 44 and a right transmission block 43. The left transmission block 44 and the right transmission block 43 are symmetrically connected to both sides of the synchronous belt 473 of the transmission device 47. Reversing the synchronous belt 473 causes the left stretching mechanism 3A and the right stretching mechanism 3B arranged on the left transmission block 44 and the right transmission block 43 to move in opposite directions or relative to each other, thereby stretching and contracting the cuff of the glove.

[0047] The left tensioning mechanism 3A and the right tensioning mechanism 3B are respectively located on the lower left and right sides of the limiting and fixing plate 2. The tensioning fixing plate 5 is combined with the limiting and fixing plate 2, and the driving mechanism 4 is located on the tensioning fixing plate 5.

[0049] Specifically, the lower bearing includes a lower front bearing 33 and a lower rear bearing 317. A tension spring 35 is disposed between the lower front axle screw 32 and the lower rear axle screw 318. The lower front bearing 33 and the lower rear bearing 317 are disposed on the straight track 31A or the inclined track 31B of the limiting block 31. The front claw 36 and the rear claw 38 are respectively provided with claw teeth for gripping the cuff side of the glove.

[0050] Specifically, the left transmission block 44 and the right transmission block 43 have slots on their sides, and the bottom of the slots has closed slots. The top block is disposed in the closed slot of the transmission block. In this embodiment, the left transmission block 44 and the right transmission block 43 have left slots 44A and right slots 43A respectively on their sides. The top block includes a left top block 45 and a right top block 42. The left top block 45 and the right top block 42 are disposed in the closed slots at the bottom of the left slots 44A and the right slots 43A respectively. The toothed part of the top block cooperates with the toothed part of the synchronous belt 473 and is combined with the pressure plate to press the synchronous belt 473.

[0051] In this embodiment, the pressure plate includes a right pressure plate 41 and a left pressure plate 46. The left pressure plate 46 and the right pressure plate 41 are combined with the left transmission block 44 and the right transmission block 43 respectively and press the synchronous belt 473.

[0052] Specifically, the drive device 48 includes a housing 482 and a worm gear assembly 483. The drive motor 481 is located on the right side of the housing 482, and its drive shaft is connected to the worm gear assembly 483. The worm gear assembly 483 is connected to one end of the main drive shaft 484 and the other end is connected to the main synchronous pulley 471.

[0053] Specifically, the transmission device 47 includes a guide rail seat 472, a main synchronous pulley 471, a driven synchronous pulley 475, and a synchronous belt 473. The guide rail seat 472 is mounted on the housing 482 via its left side. The other end of the main drive shaft 484 passes through the guide rail seat 472 and connects to the main synchronous pulley 471. A pad 474 is provided on the right side of the guide rail seat 472. The main synchronous pulley 471 and the driven synchronous pulley 475 are correspondingly arranged. A driven shaft 476 is connected between the driven synchronous pulley 475 and the pad 474. The synchronous belt 473 is connected between the main synchronous pulley 471 and the driven synchronous pulley 475.

[0055] Working principle of the invention: see [link / reference] Figure 6 The worm gear assembly 483 rotates under the drive shaft of the drive motor 481, which in turn drives the main drive shaft 484 and the main synchronous pulley 471 to rotate, causing the synchronous belt 473 and the driven synchronous pulley 475 to move synchronously. At the same time, the synchronous belt 473 also drives the right transmission block 43 and the left transmission block 44 to move in opposite directions or relative to each other, which also causes the right tensioning mechanism 3B and the left tensioning mechanism 3A to move in opposite directions or relative to each other. Initially, the left mechanical gripper device 330A and the right mechanical gripper device 330A... B is positioned on the inclined tracks of the left limiting block 31C and the right limiting block 31D, respectively, with the corresponding front and rear claws in the open state. At this time, the front and rear claws are provided with glove openings on both sides. Then, when the left stretching mechanism 3A and the right stretching mechanism 3B move in opposite directions, since the left limiting block 31C of the left stretching mechanism 3A and the right limiting block 31D of the right stretching mechanism 3B are fixed to the left and right sides of the limiting plate, respectively, the left mechanical claw device 330A and the right mechanical claw device 330... B moves along the inclined tracks of the left limiting block 31C and the right limiting block 31D respectively, and the front and rear claws slowly retract. Then, the left mechanical claw device 330A and the right mechanical claw device 330B respectively exit the inclined tracks of the left limiting block 31C and the right limiting block 31D and enter the straight tracks of the left limiting block 31C and the right limiting block 31D. At the same time, the front and rear claws on both sides of the glove opening clamp the sides of the glove opening respectively. Then, the left mechanical claw device 330A and the right mechanical claw device 330B move along the inclined tracks of the left limiting block 31C and the right limiting block 31D respectively. 0B continues to move along the straight track, stretching the glove opening on the left and right sides. Then, the drive motor 481 rotates in the opposite direction, and the left mechanical gripper device 330A and the right mechanical gripper device 330B move along the straight track of the left limit block 31C and the right limit block 31D respectively towards the inclined track. Then, they enter the inclined track of the left limit block 31C and the right limit block 31D respectively, and the front and rear claws open, releasing the glove opening sides and completing the expansion of the glove opening. Then, the above process is repeated.

[0056] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
