Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to an expansion mechanism used for turning over gloves. Background Art

[0002] The basic structure of a traditional computer glove machine is as follows: a front needle bed and a rear needle bed and corresponding front and rear heads are arranged between the left and right bases; a movable combination knitting needle is arranged on the needle bed, and the front and rear heads move back and forth relative to the needle bed through a slide rail assembly; a cam bottom plate is arranged on the side of the head facing the needle bed, and various cams are arranged on the cam bottom plate, and the needle butts of the combination knitting needles complete various knitting functions through the restriction and action of the cam.

[0003] When the gloves are knitted, they fall down from between the front and rear needle beds. In order to realize the automatic sorting of the fallen gloves, the applicant applied for a series of prior patents related to automatic sorting of gloves, such as "CN113604954B", etc., by setting an automatic grabbing device between the front and rear needle beds to neatly stack the gloves on the receiving platform. After that, the applicant applied for " Automatic strapping system CN115593680A", combined with the "pushing device CN115384860A", the fully automatic process of gloves production, sorting and bundling is realized.

[0004] Furthermore, according to different requirements, some gloves need to be turned over after knitting to facilitate subsequent labeling. Therefore, the applicant designed a process for automatic turning over before stacking and sorting in "CN117107504A Glove Turning Over and Stacking Finishing Process". The technical solution involved requires positioning the cuff of the glove (i.e., the wrist opening of the glove), inserting an expansion mechanism into the cuff of the glove, and then inserting the glove into the hand mold after the glove is stretched open.

[0005] In the existing expansion mechanism, the expansion claws are in a horizontal position, and when the automatic grabbing device transports the gloves out of the glove machine, the cuffs of the gloves are in an inclined position, so precise positioning is required to transfer the gloves from the grabbing device to the expansion mechanism; this takes a long time and easily causes the cuffs of the gloves to fall off the device.

[0006] Therefore, the inventor conducted further research and developed an expansion mechanism for turning over gloves, which resulted in the present invention. Utility Model Content

[0007] The utility model aims to provide an expansion mechanism for turning over gloves, which can improve the working efficiency of gloves in the automatic turning over process.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] An expansion mechanism for turning over a glove, comprising

[0010] A pair of expansion claws are pivotally connected to their respective slides, and the slides can move along the guide rod. The tail ends of the expansion claws are pivotally connected to the lifting rod, and the bottom ends of the lifting rods are against slide rails of different heights. When the expansion claws move horizontally along the guide rod with the slide, the height of the lifting rod changes, thereby pushing the expansion claws to swing.

[0011] The expansion claws of the original expansion mechanism do not have a swinging function. Through the above design, the expansion claws can not only have the function of opening the cuff of the glove, but also can be aligned with the inclined cuff of the glove by swinging.

[0012] Furthermore, a guide groove is provided on the slide seat, and a lifting rod and a sliding block are respectively provided on both sides of the guide groove, and the sliding block is connected to the lifting rod.

[0013] The guide groove and the slider are used to limit and guide the travel of the lifting rod.

[0014] Furthermore, the two sides of the slide rail are higher and the middle part is lower, and the lifting rod is in contact with the slide rail through a rolling member.

[0015] The expansion claws are in an inclined state at the initial position, and when the lifting rod moves up on the slide rail, the expansion claws are in an open and flat state.

[0016] Furthermore, the expansion claw includes a fixed claw and a movable claw, the fixed claw is linked with the lifting rod, and the movable claw is arranged in the fixed claw and can slide relatively.

[0017] Preferably, the cuffs of the gloves need to expand not only leftwards and rightwards, but also frontwards and backwards, so that the cuffs can be stretched as wide as possible.

[0018] Furthermore, guide plates are arranged above both sides of the slide rail, and the guide plates are provided with beveled edges. When the expansion claw slides on the guide rod, the tail end of the movable claw slides along the beveled edge.

[0019] The movable claw is opened relative to the fixed claw by the guide plate.

[0020] Furthermore, a reset spring is provided on the movable claw, and the other end of the reset spring is connected to the fixed claw.

[0021] The movable claw is pushed open by the guide plate, and the movable claw is reset by pulling it back by the reset tension spring.

[0022] Furthermore, the lifting rod is an L-shaped structure, the upper part of which is located between two rollers, and the rollers are both arranged on the fixing claws.

[0023] Furthermore, the slide is arranged on a screw rod, and the screw rod is driven by a motor.

[0024] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0025] The expansion claws of the expansion mechanism are provided with a swinging ability, so that the expansion claws are more flexible in the process of automatically turning over the gloves, thereby improving the accuracy of the expansion mechanism in conveying the gloves, thereby improving the production efficiency.

[0033] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown, an expansion mechanism for turning over a glove comprises a base plate 1 (the base plate 1 is perpendicular to the ground in actual application); a guide rod 2 is arranged horizontally on the base plate 1, a pair of slides 3 are arranged on the guide rod 2, and the slides 3 are driven by a screw rod 31 parallel to the guide rod 2 to achieve lateral movement, and the screw rod 31 is driven by a motor 32 arranged on the side of the base plate 1.

[0035] The upper end of the slide 3 is pivotally connected to the expansion seat 4, and the expansion seat 4 is provided with a fixed claw 41 and a movable claw 42 (the claw portion and the claw body are perpendicular to each other); the fixed claw 41 is fixed relative to the expansion seat 4, and the movable claw 42 passes through the middle of the expansion seat 4 and can move relatively, and the movable claw 42 and the expansion seat 4 are also connected by a reset tension spring 43. The expansion seat 4 and the fixed claw 41 can be regarded as the same component, but for the convenience of processing, they are separated into two components for description in this embodiment.

[0036] A guide groove is provided on the slide seat 3, and a lifting rod 5 and a sliding block 51 are respectively arranged on both sides of the guide groove, and the sliding block 51 is connected to the lifting rod 5; wherein, the lifting rod 5 is an L-shaped structure, and its shorter side is relatively horizontally arranged, and is clamped by two rollers 44 arranged on the expansion seat 4, and a roller 52 is also provided at the lower end of the lifting rod 5, and the roller 52 is located on the slide rail 6. The direction of the slide rail 6 is consistent with that of the guide rod 2, but its two sides are higher and the middle is lower.

[0037] like Figure 2 , Figure 3 As shown, when the lifting rod 5 moves to both sides of the base plate 1, the position of the sliding rail 6 is lifted, the position of the lifting rod 5 changes, so that the expansion seat 4 swings, and finally the fixed claw 41 and the movable claw 42 are both in a flat state (relative to the base plate 1). At this time, corresponding guide plates 7 are provided on both sides of the base plate 1, and the guide plates 7 are provided with a beveled edge on the side close to the movable claw 42. When the expansion seat 4 moves to both sides, the guide plates 7 can push the movable claw 42 to extend outward relative to the fixed claw 41; when the expansion seat 4 returns to both sides, since the movable claw 42 is no longer affected by the guide plates 7, the movable claw 42 can be returned to its original position by the reset tension spring 43.

[0038] In the above process, Figure 1 The state is the state when the expansion mechanism is inserted into the cuff of the glove. When the cuff of the glove is inserted by the two expansion claws (including the fixed claw 41 and the movable claw 42), the motor 32 drives the screw rod 31 to move, so that the expansion claws are stretched left and right and front and back. In the stretching process, the glove is transformed from an inclined state to a vertical state, thereby facilitating the operation of the subsequent flipping device.

[0039] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
