Detailed Description

The utility model is illustrated by the following examples in which:

Embodiment one:

The transmission device of the embroidery machine, for example as shown in fig. 1 and 2, mainly comprises an upper shaft and a lower shaft 2. The upper shaft is a shaft piece which is connected with a rotating motor and can rotate to drive the embroidery machine head to work.

For example, in fig. 1, there is a first shaft member 1a, and a plurality of embroidery heads 7 are provided on the first shaft member 1a at intervals along the extending direction of the first shaft member 1 a. The end part of the first shaft element 1a can be connected with a rotating motor in a transmission way, and the rotating motor drives the first shaft element 1a to rotate, so that the embroidery machine head 7 can be driven to perform needle puncturing action. At this time, the first shaft member 1a serves as an upper shaft in the present utility model.

Meanwhile, a plurality of shuttles 4 are disposed at intervals in the extending direction of the lower shaft 2 on the lower shaft 2, and the lower shaft 2 is in driving connection with the first shaft member 1a as the upper shaft at this time. Specifically, in this embodiment, as shown in fig. 1, the end of the lower shaft 2 is in transmission connection with the end of the first shaft member 1a through a transmission belt structure, so that the first shaft member 1a rotates and drives the lower shaft 2 to synchronously rotate, thereby driving the rotating shuttle of the shuttle bed 4 to cooperate with the needle in the embroidery machine head 7 to realize a complete embroidery motion. Of course, besides the driving belt structure, the end part of the lower shaft 2 can be connected to the first shaft member 1a in a driving way through a gear structure, so that the lower shaft 2 can be synchronously rotated while the first shaft member 1a rotates.

Or for example as shown in fig. 2, there is a first shaft element 1a, and a second shaft element 1b which is compliant (preferably parallel, but allowing for a certain angular deviation in view of production and installation process limitations) to the first shaft element 1 a. The embroidery heads 7 are disposed on the first shaft member 1a at intervals along the extending direction of the first shaft member 1 a.

The second shaft element 1b is on the one hand connected to a second shaft element rotation motor output shaft 901 of a second shaft element rotation motor 9 by a first transmission belt 10 in a transmission manner; on the other hand, the first shaft piece 1a is connected in a transmission way through a plurality of second transmission belts 11; the second shaft member rotating motor 9 drives the second shaft member 1b to rotate by driving the second shaft member rotating motor output shaft 901 to rotate, and then drives the first shaft member 1a to rotate, so that the embroidery machine head 7 can be driven to perform the needle puncturing action. At this time, the second shaft member 1b serves as an upper shaft in the present utility model.

Meanwhile, the lower shaft 2 is connected to the end of the first shaft member 1a by a belt structure by driving the end of the lower shaft 2 to the end of the first shaft member 1a as described above, so that the lower shaft 2 can be connected to the first shaft member 1a and thus the second shaft member 1b as the upper shaft at this time by driving.

It should be noted that, the second shaft member 1b may be rotatably connected to a plurality of bearings fixedly connected to the frame of the embroidery machine, that is, the plurality of bearings support the second shaft member 1b together, and by providing a plurality of second driving belts 11, especially by providing a plurality of second driving belts 11 at intervals in the middle area of the first shaft member 1a, the second shaft member 1b is in driving connection with the first shaft member 1a, so that not only the first shaft member 1a can be driven to rotate, but also the middle area of the first shaft member 1a can be driven to be supplemented, thereby solving the problems of increased load caused by the long length of the first shaft member 1a and the large number of embroidery machine heads 7, and further poor rotation synchronism of the first shaft member 1 a.

For the lower shaft 2, a plurality of shuttles 4 are arranged at intervals on the lower shaft 2 along the extending direction of the lower shaft 2, resulting in an increase in the load of the lower shaft 2; moreover, the transmission of the end part of the lower shaft 2 is difficult to transmit to the middle area of the shaft piece, so that the deflection of the middle area of the lower shaft 2 is increased, the synchronous rotation of the lower shaft 2 is greatly problematic, and further the synchronous rotation with the upper shaft cannot be well realized, so that the synchronous rotation of the upper shaft and the lower shaft is poorer, the accurate embroidery work cannot be realized, various problems are easily generated during the work of the embroidery machine, and the stability of the work of the embroidery machine is damaged.

Therefore, the lower shaft 2 needs to be supplemented with a transmission.

However, on one hand, the arrangement of the shuttle beds 4 is denser, the transmission belts with larger widths cannot be installed to directly carry out additional transmission connection on the lower shaft 2, and only the transmission belts with smaller widths can be installed, so that the transmission effect is poor, or a plurality of small-width transmission belts are needed, and the whole transmission structure is complex and the cost is high; on the other hand, more lubricating oil exists in the shuttle race 4, and the extra transmission connection is directly carried out on the lower shaft 2 through the small-width transmission belt, so that transmission slip easily occurs, and the oil proofing and anti-slip problems of the small-width transmission belt need to be considered.

In particular, in the case of small-head embroidery machines, the shed 4 is arranged more closely, which on the one hand does not leave enough space on the lower shaft 2 to mount a synchronous pulley having a certain width; on the other hand, due to the compact arrangement structure, the requirement on lubricating oil is larger, the synchronous belt is easier to slip, and the problem that the service life of the synchronous belt is influenced due to the fact that the lubricating oil erodes the synchronous belt is also easier to occur.

In this embodiment, as shown in fig. 2 to 4, a driven gear 201 is fixedly connected to the lower shaft 2, and the driven gear 201 is preferably disposed in a middle region of the lower shaft 2; and a transmission shaft 3 is arranged on one side of the lower shaft 2, the transmission shaft 3 is in transmission connection with the upper shaft through a transmission belt assembly 5, namely, when the first shaft part 1a is used as the upper shaft, the transmission shaft 3 is in transmission connection with the first shaft part 1a through the transmission belt assembly 5, at the moment, the second shaft part 1b and the second transmission belt 11 can be used as part of the transmission belt assembly, or when the second shaft part 1b is used as the upper shaft, the transmission shaft 3 is in transmission connection with the second shaft part 1b through the transmission belt assembly 5. Meanwhile, there is a transmission assembly 6, such as a gear set constituted by a first transmission gear 601 and a second transmission gear 602 mentioned below, or a chain, between the transmission shaft 3 and the driven gear 201, which transmits the rotation of the transmission shaft 3 to the driven gear 201.

As shown in fig. 1 and fig. 2, the driving belt assembly 5 is preferably disposed in the backpack frame 8 and is adapted to extend and distribute in a bent shape so as to avoid interfering with the movement of the sewing material.

Specifically, as shown in fig. 2, the belt assembly 5 in this embodiment includes a first transverse belt 501, a vertical belt 502, and a second transverse belt 503.

As shown in fig. 2, the left end of the first transverse driving belt 501 is in driving connection with the first driving wheel 504, and the right end is in driving connection with the third driving wheel 507; the lower end of the vertical transmission belt 502 is in transmission connection with the second transmission wheel 506, and the upper end is in transmission connection with the fourth transmission wheel 509; the left end of the second transverse driving belt 503 is in driving connection with the sixth driving wheel 5012, and the right end is in driving connection with the fifth driving wheel 5010. The rotational energy of the second shaft member 1b is transmitted to the drive shaft 3 via the drive belt assembly 5.

The belt assembly 5 may also include structure for biasing and tensioning the belt.

As shown in fig. 2, a mounting plate 5013 is disposed on one side of the first transverse driving belt 501, a first pressing wheel 5014 for pressing the upper end belt of the first transverse driving belt 501 downward is rotatably connected to the mounting plate 5013, a positioning rod 5015 is detachably connected to the mounting plate 5013, and a first tensioning wheel 5016 inserted into the middle cavity of the first transverse driving belt 501 and pressing the lower end belt of the first transverse driving belt 501 downward is rotatably connected to the positioning rod 5015. There are a plurality of portions on the mounting plate 5013 to which the positioning lever 5015 is connected to be able to change the pressing position of the first tension pulley 5016 against the first traverse belt 501.

A mounting rod 5017 is arranged on one side of the vertical transmission belt 502, and a second pressing wheel 5018 for transversely pressing the vertical transmission belt 502 is rotationally connected to the mounting rod 5017.

A third connecting rod 5011 is arranged above the second transverse driving belt 503, and a third pressing wheel 5019 for pressing the upper end belt of the second transverse driving belt 503 downwards is rotationally connected to the third connecting rod 5011; in the middle cavity of the second transverse driving belt 503, a fourth connecting rod 5020 is arranged, and a second tensioning wheel 5021 for pushing the lower end belt of the second transverse driving belt 503 downwards is rotationally connected to the fourth connecting rod 5020.

Moreover, the upper shaft is used as a power mechanism for the supplementary transmission of the lower shaft 2, so that the rotation synchronism of the upper shaft and the lower shaft 2 can be better optimized, and the working stability of the embroidery machine is further optimized and improved.

Compared with a driving belt, the rigid driven gear 201 has smaller requirement on the size, stable driving can be realized by adopting the driven gear 201 with smaller width, and the driven gear is more suitable for the narrow space requirement on the lower shaft 2. Moreover, the driven gear 201 is in transmission connection with the transmission shaft 3 arranged on the side edge of the lower shaft 2 through the transmission assembly 6, so that the transmission connection point of the transmission belt assembly 5 can be moved outwards, namely, the transmission connection point of the transmission belt assembly 5 is moved to the transmission shaft 3 from the lower shaft 2 which is connected with a transmission belt with narrow space and inconvenient width, and the transmission shaft 3 can be installed at a more open position according to the actual environment. Particularly, the device can be more suitable for the assembly environment of the small-head-distance embroidery machine to carry out transmission supplement on the lower shaft 2, and can improve the self-rotation synchronism of the lower shaft 2 so as to better realize the synchronous rotation with the upper shaft, further improve the rotation synchronism of the upper shaft and the lower shaft 2 and realize the optimization and the improvement of the working stability of the embroidery machine.

In this embodiment, the transmission assembly 6 includes a first transmission gear 601 fixedly connected to the transmission shaft 3, and a plurality of (in this embodiment, a plurality of refers to one or more) second transmission gears 602 that drivingly connect the first transmission gear 601 to the driven gear 201; the first transmission gear 601 is disposed outside the interval area between the two support frames 12, so as to avoid interference with the mounting structure of the first transmission wheel 504. The power of the transmission shaft 3 can be stably transmitted to the lower shaft 2 by adopting the transmission component 6 with a gear set structure, and lubricating oil in the shuttle bed 4 can directly lubricate the gear structure, so that the gear transmission is smoother and smoother.

Further, the extending direction of the transmission shaft 3 may be disposed at an angle to the extending direction of the lower shaft 2, for example, using a worm gear structure.

In this embodiment, as shown in fig. 3, the extending direction of the transmission shaft 3 is preferably compliant (preferably parallel to, but in consideration of production and installation process limitations, a certain angle deviation is allowed) with the extending direction of the lower shaft 2, so that the transmission shaft 3 can transmit rotation to the lower shaft 2 more smoothly and smoothly, thereby ensuring the supplementary stability of the transmission of the lower shaft 2 and further optimizing the working stability of the embroidery machine.

Meanwhile, the number of the second transmission gears 602 is preferably odd, so that the rotation direction of the transmission shaft 3 is the same as the rotation direction of the lower shaft 2, and the rotation of the second shaft member 1b is conveniently and directly transmitted to the transmission shaft 3 without considering an additional rotation direction adjusting structure.

In this embodiment, in order to make the rotation of the transmission shaft 3 be transferred to the lower shaft 2 more smoothly and smoothly, the driven gear 201, and/or the first transmission gear 601, and/or the second transmission gear 602 are cylindrical gears.

Meanwhile, the driven gear 201, the first transmission gear 601, and the second transmission gear 602 are helical gears or spur gears.

Further, at the time of installation, the drive shaft 3 may be partially disposed inside the shed 4, partially disposed outside the shed 4, and the first transverse belt 501 is drivingly connected to the portion of the drive shaft 3 disposed outside the shed 4.

However, the internal structure of the shed 4 is considered to be relatively narrow, and the drive shaft 3 is likely to interfere with other members in the shed 4.

The transmission shaft 3 can be externally arranged on the shuttle bed 4, so that the influence of the lubricating oil in the shuttle bed 4 on the transmission connection of the first transverse transmission belt 501 on the transmission shaft 3 can be better avoided.

Meanwhile, as shown in fig. 3, considering the space requirement of the embroidery machine, the present embodiment is provided with a supporting frame 402 connected to the shuttle bed 4 at the side of the avoidance hole 401; the support frame 402 is provided with a second transmission gear mounting shaft 403 to which the second transmission gear 602 is rotatably connected, and the second transmission gear 602 may be directly rotatably connected to the second transmission gear mounting shaft 403.

Further, as shown in fig. 4, a top cover 13 fixedly connected to the shuttle bed 4 may be disposed above the driven gear 201 and the second transmission gear 602 disposed in the inner portion of the shuttle bed 4, which forms a covering protection for the driven gear 201 and the second transmission gear 602 disposed in the inner portion of the shuttle bed 4 from above, so as to avoid some thread ends, material particles and the like falling to the driven gear 201 above the shuttle bed 4 and affecting the transmission of the driven gear 201.
