Description

Technical Field

[0001] This utility model relates to the field of glove production equipment technology, and in particular to a glove blank alignment device. Background Technology

[0002] The glove preform is the core material of the dipped glove. It is a seamless tubular lining woven from elastic knitted fibers (such as nylon or polyester), featuring the structure of the wrist, palm, and fingers, providing a three-dimensional support framework for the subsequent dipped rubber. During dipping, the rubber penetrates and adheres between the fibers, forming a strong bond. The glove preform determines the basic shape, size, and fit of the glove, and as the inner layer in contact with the skin, it gives the final product good breathability, comfort, and tear resistance.

[0003] In the process of setting up the hand mold before the glove preform is dipped in glue, there are two main traditional operation methods: manual setting and automated setting. The two methods show significant differences in efficiency and accuracy.

[0004] In the manual glove fitting process, operators must manually open the wrist opening of the glove blank, align it with the fingers of the hand mold, and then slip the five fingers of the glove blank onto the corresponding fingers of the hand mold. This process requires repeated pulling and adjusting to ensure a proper fit. This manual operation, due to the repetitive mechanical action of fitting each glove individually, is not only cumbersome and lengthy, leading to low work efficiency, but also causes extreme physical strain on workers due to prolonged periods of bending over and raising their arms, easily resulting in wrist and lower back injuries. More importantly, as gloves are high-frequency consumable protective equipment, the large-scale production of gloves leads to a surge in the demand for manual fitting, and the resulting increase in labor costs raises the overall production cost of the product.

[0005] Automated glove fitting achieves batch processing through mechanical structures: several glove blanks are neatly arranged in a preset order, then multiple upper grippers (usually corresponding to the number of hand molds) in the same row simultaneously clamp the wrist of the glove blanks. Simultaneously, the corresponding lower grippers open, widening the wrist opening of the glove blank. A specialized opening device further expands the opening, ultimately allowing for precise fitting into the corresponding hand mold. This method completes the fitting of an entire row of hand molds in a single operation, significantly improving production efficiency. However, this method has a significant drawback: due to variations in the glove blank's placement and angle, the gripping position is difficult to unify completely. This leads to deviations in the relative position of the glove blank and the hand mold during fitting, potentially causing deviations from the hand mold's central axis or misalignment of a finger. Ultimately, this affects the uniformity of the adhesive layer distribution during impregnation and the fit of the finished glove, reducing product precision. Utility Model Content

[0006] In view of this, the technical problem to be solved by this utility model is to provide a glove blank alignment device that can align and unify the position of the glove blank before blanking, thereby improving the accuracy and automation efficiency of blanking, reducing labor intensity, enhancing product consistency, and reducing costs.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] Glove blank alignment device, including a horizontally set support;

[0009] A flap is rotatably mounted on the bracket, and a limiting part is provided on the flap. The limiting part is located above the front edge of the flap or above the rear edge of the flap.

[0010] The bracket is equipped with a power mechanism, which is connected to the flap. The power mechanism drives the flap to be in a horizontal state, or in a forward tilting state, or in a backward tilting state.

[0011] Preferably, the power mechanism includes a rotary shaft and a power component;

[0012] The rotary shaft is rotatably mounted on the bracket via a bearing seat, and a connecting support is installed on the rotary shaft, the connecting support being connected to the flap.

[0013] The power component is mounted on the bracket and is connected to the rotary shaft via a transmission.

[0014] Preferably, the power component is a motor, which is mounted on the bracket, and the motor is connected to the rotary shaft via a transmission mechanism.

[0015] Preferably, the transmission mechanism includes a driving gear and a driven gear meshing with it, the driving gear being mounted on the power shaft of the motor, and the driven gear being mounted on the rotary shaft.

[0016] Preferably, the power component is a rotary cylinder, which is mounted on the bracket, and the actuating end of the rotary cylinder is connected to one end of the rotary shaft.

[0017] Preferably, the flap is mounted above the bracket via a flipping assembly;

[0018] The power mechanism includes a telescopic cylinder, which is installed between the flap and the bracket.

[0019] Preferably, the flipping assembly includes a lower bearing seat, an upper bearing seat, and a connecting shaft connecting the two. The lower bearing seat is mounted on the bracket, and the upper bearing seat is mounted below the flip plate.

[0020] Preferably, the telescopic cylinder is a double-stroke cylinder, the telescopic cylinder is hinged to the bracket, the piston rod of the telescopic cylinder is threadedly connected to the connecting member, and the connecting member is hinged to the flap.

[0021] Preferably, the flap plate is provided with a plurality of limiting and guiding structures, which are disposed close to the limiting part.

[0022] Preferably, the limiting and guiding structure includes a limiting structure and a guiding structure, the limiting structure being disposed close to the limiting part, and the guiding structure being disposed on the outside of the limiting structure along the inclination direction of the flap;

[0023] The limiting structure includes two limiting plates, which are arranged opposite to each other and their positions are adjustable.

[0024] The guide structure includes two guide plates, which are inclined outwards in an open shape and their positions are adjustable.

[0025] After adopting the above technical solution, the beneficial effects of this utility model are:

[0026] The glove blank alignment device of this application includes a horizontally arranged support; a flap is rotatably mounted on the support, and a limiting part is provided on the flap, which is located above the front edge of the flap or above the rear edge of the flap; a power mechanism is mounted on the support, and the power mechanism is poweredly connected to the flap, driving the flap to be in a horizontal state, a forward tilting state, or a backward tilting state. Before the upper gripper grasps the glove blank and prepares to open its wrist, the glove blank is first placed on the flap, at which time the flap is in a horizontal state. Then, the power mechanism drives the flap to tilt forward, that is, to tilt towards the side closer to the limiting part. The glove blank slides to the position of the limiting part under the action of gravity, and is positioned by the limiting part. Subsequently, the upper gripper grasps the aligned glove blank and moves it to the lower gripper. The two work together to complete the opening operation of the wrist opening. During this process, the flipping and sliding motions, combined with the limiting part, align and unify the position of the glove blank, effectively improving the accuracy of subsequent blank assembly and the efficiency of automated production. At the same time, it reduces labor intensity, enhances product consistency, and saves production costs.

[0027] Since the glove blanks being clamped are typically stacked in multiple layers, the upper gripper may pick up multiple stacked glove blanks at once. For example, if two glove blanks are stacked on the flip plate, after alignment, the upper gripper may only hold the topmost glove blank and move it downstream, leaving another glove blank on the flip plate. If not cleaned promptly, this will interfere with subsequent alignment operations. Therefore, the power mechanism can also drive the flip plate to tilt backward, i.e., tilt it away from the limiting part. The remaining glove blank can then slide off the other side of the flip plate under gravity, thus automatically cleaning the flip plate surface and ensuring the normal operation of subsequent alignment processes.

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0046] Example 1

[0047] like Figures 1 to 4 As shown, this utility model includes a horizontally arranged support 1; a flap 2 is rotatably mounted on the support 1, and a limiting part 21 is provided on the flap 2. The limiting part 21 is located above one side of the flap 2 along the tilting direction of the flap 2, that is, the limiting part 21 is located above the front side of the flap 2 or above the rear side of the flap 2; a power mechanism 3 is installed on the support 1, and the power mechanism 3 is poweredly connected to the flap 2. The power mechanism 3 drives the flap 2 to be in a horizontal state, or in a forward tilting state, or in a backward tilting state; when in the forward tilting state, that is, the flap 2 tilts towards the side closer to the limiting part 21; when in the backward tilting state, that is, the flap 2 tilts away from the limiting part 21.

[0048] Before the upper gripper (not shown in the figure) grasps the glove blank and prepares to open its wrist, the glove blank is first placed on the flip plate 2, which is in a horizontal position. Then, the power mechanism 3 drives the flip plate 2 to tilt forward, and the glove blank slides to the position of the limiting part 21 under the action of gravity. The limiting part 21 positions the glove blank. Subsequently, the upper gripper grasps the aligned glove blank and moves it to the lower gripper. The two work together to complete the opening operation of the wrist. In this process, the flipping and sliding motion, combined with the positioning part 21, aligns and unifies the position of the glove blank, effectively improving the accuracy of subsequent blank assembly and the efficiency of automated production. At the same time, it reduces labor intensity, enhances product consistency, and saves production costs.

[0049] Since the glove blanks being clamped are typically stacked in multiple layers, the upper gripper may pick up multiple stacked glove blanks at once. For example, if two glove blanks are stacked on the flip plate 2, after alignment, the upper gripper may only hold the topmost glove blank and move it downstream, leaving the other glove blank on the flip plate 2. If not cleaned in time, this will interfere with subsequent alignment operations. Therefore, by tilting the flip plate backward, the remaining glove blank can slide off the other side of the flip plate 2 under gravity, thus automatically cleaning the surface of the flip plate 2 and ensuring the normal progress of subsequent alignment processes.

[0050] Preferably, the power mechanism 3 includes a rotating shaft 31 and a power component; the rotating shaft 31 is rotatably mounted on the bracket 1 via a bearing seat 32, and a connecting support 33 is mounted on the rotating shaft 31, which is connected to the flap 2; the power component is mounted on the bracket 1 and is connected to the rotating shaft 31 in a transmission manner.

[0051] Preferably, the power component is a motor 34, which is mounted on the bracket 1. The motor 34 is connected to the rotating shaft 31 via a transmission mechanism 4. The transmission mechanism 4 includes a driving gear 41 and a driven gear 42 meshing with it. The driving gear 41 is mounted on the power shaft of the motor 34, and the driven gear 42 is mounted on the rotating shaft 31.

[0052] In this embodiment, a motor 34 is used as the power component, preferably a servo motor. The rotation of the power shaft of the motor 34 drives the rotation of the rotary shaft 31 through the meshing of the active gear 41 and the driven gear 42, thereby driving the flip plate 2 to switch between horizontal, forward tilting and backward tilting states.

[0053] The flap 2 is provided with several limiting and guiding structures, which are located near the limiting part 21. The limiting and guiding structures include a limiting structure 6 and a guiding structure 7. The limiting structure 6 is located near the limiting part 21, and the guiding structure 7 is located outside the limiting structure 6 along the tilting direction of the flap 2. The limiting structure 6 includes two limiting plates 61, which are arranged opposite each other and are adjustable in position. The guiding structure 7 includes two guiding plates 71, which are inclined outward in an open shape and are adjustable in position.

[0054] In this embodiment, the limiting plate 61 and the guide plate 71 have the same structure and are both installed on the flip plate 2 by bolts. The flip plate 2 has a long through hole, which is set along the length of the flip plate 2. Therefore, the position of the limiting plate 61 or the guide plate 71 can be adjusted by the cooperation of the bolts and the long through hole, so that the two limiting plates 61 are set opposite to each other, or the two guide plates 71 are set in an open shape.

[0055] When placing the glove blank, it may be placed at an angle. If it is not guided and limited, it will directly affect the subsequent alignment effect. By setting the limiting structure 6 and the guiding structure 7 on the flip plate 2, the glove blank can be guided first, so that its wrist can slide between the two limiting plates 61 to achieve the limiting, thereby ensuring that the subsequent opening operation can be carried out normally and effectively improving the alignment accuracy.

[0056] Example 2

[0057] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown in the figure, this embodiment discloses a glove blank alignment device. The difference from the first embodiment is that in this embodiment, the power component is a rotary cylinder 35, which is mounted on the bracket 1. The actuating end of the rotary cylinder 35 is connected to one end of the rotary shaft 31.

[0058] In this embodiment, the rotary cylinder 35 is directly connected to the rotary shaft 31, driving it to rotate, which in turn drives the flip plate 2 to rotate, thereby realizing the alignment and cleaning of the glove blanks. This eliminates the need for the transmission mechanism 4, simplifies the connection structure, reduces maintenance difficulty and frequency, and lowers production costs.

[0059] Example 3

[0060] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown in the previous embodiment, this embodiment discloses a glove blank aligning device. The difference from Embodiment 1 is that in this embodiment, the flip plate 2 is mounted above the bracket 1 via a flipping assembly 5, while in Embodiments 1 and 2, the flip plate 2 is mounted on a rotating shaft 31. The flipping assembly 5 includes a lower bearing seat 51, an upper bearing seat 52, and a connecting shaft 53 connecting the two. The lower bearing seat 51 is mounted on the bracket 1, and the upper bearing seat 52 is mounted below the flip plate 2.

[0061] In this embodiment, the power mechanism 3 includes a telescopic cylinder 36, which is installed between the flap 2 and the bracket 1. Preferably, the telescopic cylinder 36 is a double-stroke cylinder, which is hinged to the bracket 1. The piston rod of the telescopic cylinder 36 is threadedly connected to the connecting member 37, which is hinged to the flap 2.

[0062] The double-stroke cylinder acts as a power component, driving the flap 2 to switch between horizontal, forward-tilted, and backward-tilted states. Specifically, when the double-stroke cylinder is at the end of the first stroke, the flap 2 is in a horizontal state; when the double-stroke cylinder is at the end of the second stroke, the flap 2 is in a backward-tilted state, aligning the glove blanks; when the double-stroke cylinder is fully retracted, the flap 2 is in a forward-tilted state, cleaning the glove blanks. If any glove blanks remain on the flap 2, they will slide off under their own weight.

[0063] The piston rod of the telescopic cylinder 36 is threadedly connected to the connector 37, and the connector 37 is hinged to the flap 2. By adjusting the connection position of the connector 37 on the piston rod of the telescopic cylinder 36, the extension length of the piston rod of the telescopic cylinder 36 can be adjusted, thereby adjusting the tilt angle of the flap 2, so that glove blanks of different weights can be aligned, thus meeting the usage requirements.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
