Description

Technical Field

[0001] The utility model relates to the field of glove machines, and particularly refers to a glove rolling clamping device. Background Art

[0002] The basic structure of a traditional computerized glove machine is as follows: between the left and right bases, there are front and rear needle beds and corresponding front and rear machine heads; movable combined knitting needles are arranged on the needle beds, and the front and rear machine heads reciprocate horizontally relative to the needle beds through slide rail assemblies. On the side of the machine head facing the needle bed, there is a triangular base plate, and various triangles are arranged on the triangular base plate. The needle heels of the combined knitting needles complete various knitting functions through the restriction and action of the triangles.

[0003] When the glove is knitted, it drops downward between the front and rear needle beds. In order to realize the automatic sorting of the dropped gloves, the applicant has applied a series of prior patents related to glove automatic sorting, such as "CN113604954B", etc. By arranging an automatic grasping device between the front and rear needle beds, the gloves are neatly stacked on the receiving platform. After that, the applicant has also applied for "Automatic Strapping System CN115593680A", in cooperation with "Pushing Device CN115384860A", to realize the full-automatic process of glove production, sorting, and strapping.

[0004] Also, according to different requirements, some gloves need to be turned over after knitting to facilitate subsequent labeling. Therefore, in the "CN117107504A Glove Turning and Stacking and Sorting Process", the applicant has designed an automatic turning process before stacking and sorting. The technical solutions involved therein require positioning the cuff (i.e., the opening of the glove at the wrist) of the glove in order to insert the clamping and expanding mechanism into the glove cuff.

[0005] The applicant has applied for a glove machine cuff positioning and clamping device in CN117888271A to cooperate with the above inventive concept. However, after actual production tests, it is found that when the rolling elements are arranged in a passive and an active manner in the two arms that can relatively open and close of the grasping part, although it is theoretically feasible, in actual production effects, wrinkles may occur on the glove on the passive side.

[0006] Therefore, the inventor has conducted further research on this and developed a glove rolling clamping device, from which this case is generated. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a glove rolling clamping device, which can better realize the positioning of the glove cuff when the glove is knitted and turned over.

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

[0009] A glove rolling clamping device includes a swing arm and a fixed arm that can both rotate on their own axes. The swing arm and the fixed arm are both linked to a driving motor through a synchronous belt and a gear. Among them, the one-way gear linked to the swing arm can only be driven to rotate on its own axis by the synchronous belt in a single direction, and is locked in the other direction. That is, when the one-way gear is locked, the swing arm moves away from the fixed arm, and when the one-way gear can rotate with the synchronous belt, the swing arm approaches the fixed arm and rotates on its own axis.

[0010] The opening and closing as well as the self-rotation between the swing arm and the fixed arm are realized by a single driving device, while in the previously disclosed patents, the structure of a swing rod and a check claw was mainly adopted.

[0011] Furthermore, the driving motor is linked to the one-way gear through a first-stage synchronous belt, the one-way gear is linked to the swing arm through a second-stage synchronous belt. At the same time, the one-way gear meshes with a passive gear, and the passive gear is linked to the fixed arm through another second-stage synchronous belt. The swing arm and the fixed arm are connected by a tension spring.

[0012] Furthermore, the end of the rotating shaft of the fixed arm is fixed through a bracket, and the bracket is connected to the motor base.

[0013] Since the positioning of the glove cuff is to pull the glove downward between the swing arm and the fixed arm, the swing arm and the fixed arm are required to have a "downward" pulling force.

[0014] Furthermore, an eccentric wheel is arranged on the side of the second-stage synchronous belt driven by the one-way gear.

[0015] The eccentric wheel is used to adjust the tension of the second-stage synchronous belt.

[0016] Furthermore, when the one-way gear rotates clockwise and the passive gear rotates counterclockwise, the swing arm is driven to rotate clockwise and the fixed arm rotates counterclockwise.

[0017] Furthermore, the driving motor is linked to a driving gear through a first-stage synchronous belt, the driving gear is linked to the fixed arm. At the same time, the driving gear is also linked to the one-way gear through a second-stage synchronous belt, and the one-way gear is linked to the swing arm through a third-stage synchronous belt.

[0018] Furthermore, one ends of the driving gear, the fixed arm, and the one-way gear are all arranged on the same bracket.

[0019] Furthermore, an eccentric wheel is arranged on the side of the first-stage synchronous belt.

[0020] Furthermore, both the swing arm and the fixed arm include a swing arm and a rotating shaft. The rotating shaft is in direct contact with the glove, and the swing arm is perpendicularly arranged with respect to the rotating shaft.

[0021] After adopting the above scheme, compared with the prior art, the present utility model has the following advantages:

[0022] Through the cooperation of gears and synchronous belts, the swing arms and fixed arms can simultaneously meet the functions of opening / closing and rolling, thereby achieving more accurate and rapid positioning of the glove cuffs completed by the automatic knitting glove machine.

[0027] Label Description

[0028] Drive motors (11, 12), first-stage synchronous belts (21, 22), second-stage synchronizers (31, 32),

[0029] One-way gears (41, 42), swing arms (51, 52), fixed arms (61, 62),

[0030] Driven gear 71, driving gear 72,

[0031] Eccentric wheels (81, 82), third-stage synchronous belt 9, return tension spring 10. Detailed Embodiment

[0032] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0033] Embodiment 1:

[0034] As Figure 1 , 2 shown, a glove rolling clamping device includes a drive motor 11. The drive motor 11 is linked with a one-way gear 41 through a first-stage synchronous belt 21. The end of the one-way gear 41 meshes with a driven gear 71 (the tooth radius at the end of the one-way gear and the driven gear is larger than the tooth radius of the rest of the parts). The one-way gear and the driven gear are respectively linked with their own second-stage synchronous belts 31. The second-stage synchronous belts are used to drive the swing arm 51 and the fixed arm 61 to rotate. At the same time, a return tension spring 10 is arranged between the swing arm 51 and the fixed arm 61.

[0035] Since the one-way gear can only rotate clockwise but not counterclockwise in this embodiment, when the primary synchronous belt is driven counterclockwise, the swing arm is opened, that is, it is in a state of waiting to clamp the knitted glove; when the primary synchronous belt is driven clockwise, the force for opening the swing arm is removed, and under the action of the reset tension spring 10, the swing arm and the fixed arm are closed. Since the one-way gear and the driven gear rotate in opposite directions, the swing arm and the fixed arm rotate in opposite directions, so that the clamped knitted glove can be dropped from between the swing arm and the fixed arm and positioned.

[0036] Preferably, an eccentric wheel 81 is provided on the side of the secondary synchronous belt from the one-way gear to the swing arm, and the eccentric wheel is used to adjust the tension of the secondary synchronous belt.

[0037] Embodiment 2:

[0038] like Figure 3 , 4 As shown, this embodiment is consistent with the embodiment in principle, except that the primary synchronous belt 22 driven by the drive motor 12 is linked to the driving gear 72, and then the driving gear is directly linked to the gear teeth of the fixed arm 62, and is linked to the one-way gear 42 through the secondary synchronous belt 32, and the one-way gear is linked to the gear teeth of the swing arm 52 through the tertiary synchronous belt 9; and as a preference, its eccentric wheel 82 is arranged on the side of the primary synchronous belt.

[0039] The above solution can also achieve the opening and closing effect of the first embodiment.

[0040] In addition, the swing arm or fixed arm shown in the figure actually includes a rotating shaft capable of self-rotation and a swing arm connected to the rotating shaft, wherein the cylinder with a sawtooth shape linked to the synchronous belt is the rotating shaft, and the swing arm is arranged perpendicular to the rotating shaft.

[0041] 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.
