A mixed embroidery machine

Abstract

This invention discloses a hybrid embroidery machine, comprising a machine body, a main beam mounted on the machine body, a main shaft mounted on the machine body, at least one first embroidery head mounted on the main beam, and at least one winding embroidery head mounted on the main beam. As an improvement, each first embroidery head contains a first drive shaft, and each winding embroidery head contains a second drive shaft. A first transmission structure, which can be driven or disengaged, is provided between the main shaft and the first drive shaft, and a second transmission structure, which can be driven or disengaged, is provided between the main shaft and the second drive shaft. This invention uses a switching structure to switch between the first and second transmission structures, allowing either the first or second transmission structure to operate, and to disengage the other transmission structure. This ensures that during embroidery operation, the main shaft drives only one type of embroidery head through the corresponding transmission structure, reducing the load on the main shaft drive and facilitating an increase in the number of heads that can be driven.

Description

Technical Field

[0001] This invention relates to a hybrid embroidery machine. Background Technology

[0002] By combining wrap-around embroidery heads and flat embroidery heads on an embroidery machine, both wrap-around and flat embroidery can be achieved. Currently, existing flat embroidery and wrap-around embroidery heads are typically arranged sequentially on a main beam, driven directly by a single main shaft. However, in practical use, wrap-around and flat embroidery are not used simultaneously. Therefore, when one main shaft drives one of the two heads, the other mechanism is also driven, increasing the load on the main shaft and drive motor. When the main shaft and drive motor power are at their rated limits, the number of flat and wrap-around embroidery heads that can be driven is extremely limited.

[0003] In addition, a material rack needs to be installed at the bottom of the wrap embroidery machine. The distance between the wrap embroidery machine head and the main beam, which is on the same main axis as the flat embroidery machine, limits the use of a large-capacity material rack. Summary of the Invention

[0004] To address the problems existing in the use of existing hybrid embroidery, this invention provides a hybrid embroidery machine that can reduce workload, increase the number of machine heads, and increase the capacity of the embroidery material winding rack.

[0005] The technical solution of this invention to solve the existing problems is: a hybrid embroidery machine, including a machine body, a main beam disposed on the machine body, a main shaft disposed on the machine body, at least one first embroidery head disposed on the main beam, and at least one winding embroidery head disposed on the main beam. As an improvement, each first embroidery head is provided with a first drive shaft, and each winding embroidery head is provided with a second drive shaft. A first transmission structure that can be driven or disengaged is provided between the main shaft and the first drive shaft, and a second transmission structure that can be driven or disengaged is provided between the main shaft and the second drive shaft. It also includes a switching structure that can arbitrarily switch one of the first transmission structure and the second transmission structure to drive and switch the other transmission structure to disengage.

[0006] As a further improvement, the first transmission structure and / or the second transmission structure includes corresponding power transmission wheels and mounting shafts for mounting the corresponding transmission wheels; the corresponding ends of the mounting shafts are positioned and mounted on the mounting base or the corresponding machine head housing; the switching structure drives the corresponding transmission wheels to slide or the corresponding mounting shaft to arbitrarily switch the transmission between the first transmission structure and the second transmission structure.

[0007] As a further improvement, the switching structure is provided with a drive rod for sliding driving force, and the first and second transmission structures are provided with connecting parts for connecting the drive rod.

[0008] As a further improvement, the first drive shaft is provided with a first driven gear, the second drive shaft is provided with a second driven gear, the first transmission structure is provided with a first transmission gear that cooperates with the first driven gear, and the second transmission structure is provided with a second transmission gear that cooperates with the second driven gear.

[0009] As a further improvement, the main shaft is provided with a set of transmission gears that cooperate with each other between it and the first and second transmission structures.

[0010] As a further improvement, the winding embroidery head is positioned forward on the main beam relative to the first embroidery head, and a mounting base for mounting the winding embroidery head is provided between the winding embroidery head and the main beam; the first transmission structure and / or the second transmission structure are mounted on the mounting base.

[0011] As a further improvement, the first embroidery head and the wrapping embroidery head are alternately installed on the main beam; the first embroidery head is a flat embroidery head.

[0012] As a further improvement, the connecting component includes a forward / reverse seat for connecting the mounting shafts of the first and second transmission structures and a connecting block for connecting the drive rod. The forward / reverse seat is connected to the connecting block via a slot.

[0013] As a further improvement, a notch for mounting a drive motor is provided on one side of the winding embroidery machine head housing.

[0014] The mounting shaft can be slidably mounted on the mounting base or the corresponding machine head housing; or the transmission wheel can be slidably mounted on the mounting shaft.

[0015] Compared with existing structures, this invention provides a first drive shaft in each first embroidery head and a second drive shaft in each winding embroidery head. A first transmission structure that can be driven or disengaged is provided between the main shaft and the first drive shaft, and a second transmission structure that can be driven or disengaged is provided between the main shaft and the second drive shaft. By setting a switching structure, either the first transmission structure or the second transmission structure can be switched to drive, and the other transmission structure can be switched to disengage. This allows the main shaft to drive only one type of head through the corresponding transmission structure during embroidery, while stopping the drive of the other type of head. The beneficial effect is to reduce the load on the main shaft drive and to increase the number of heads driven with limited driving force. Attached Figure Description

[0024] See Figure 1-8 This embodiment includes a hybrid embroidery machine, comprising a machine body, a main beam 7 mounted on the machine body, a main shaft 3 mounted on the machine body, at least one first embroidery head 11 mounted on the main beam 7, and at least one winding embroidery head 21 mounted on the main beam 7. The number and arrangement of the first embroidery head 11 and the winding embroidery head 21 can be set according to the machine model and actual needs. See also Figure 1-3 Typically, the first embroidery machine head 11 and the wrapping embroidery machine head 21 are alternately installed on the main beam 7. In this embodiment, as an option, the first embroidery machine head is a flat embroidery machine head. Of course, other embroidery machine heads can also be used.

[0025] Each first embroidery head 11 is provided with a first drive shaft 1, and each winding embroidery head 21 is provided with a second drive shaft 2. The first and second drive shafts can serve as a drive source for the head, driving the needle bar or the needle bar and presser foot of the corresponding head to work.

[0026] The main spindle 3 is provided with a first transmission structure 4 that can be driven or disengaged between itself and the first drive shaft 1, and a second transmission structure 5 that can be driven or disengaged between itself and the second drive shaft 2. It also includes a switching structure 6 that can arbitrarily switch one of the first transmission structure 4 and the second transmission structure 5 to drive while simultaneously disengaging the other transmission structure. Preferably, the switching structure 6 can be used as needed to switch between the first transmission structure 4 and the second transmission structure 5, enabling the main spindle to drive the first drive shaft 1 while stopping the drive of the second drive shaft 2, or to switch the main spindle to drive the second drive shaft 2 while stopping the drive of the first drive shaft 1.

[0027] The first transmission structure 4 and the second transmission structure 5 are used to transmit the main shaft power to the corresponding drive shaft, and can also realize the disengagement of power. The switching structure 6 controls the power transmission and disengagement of the first transmission structure 4 and the second transmission structure 5. The first transmission structure 4, the second transmission structure 5, and the switching structure 6 can adopt existing technology structures for power transmission and switching. For example, if the first transmission structure 4 and the second transmission structure 5 are set as existing clutch structures, the switching structure 6 is a controller that controls the transmission or disengagement of power by the clutch structure.

[0028] To accommodate the structure of the embroidery machine, the first transmission structure 4 and / or the second transmission structure 5 includes corresponding power transmission wheels and mounting shafts for mounting the corresponding transmission wheels. The transmission wheels can be gears or synchronous belt pulleys, specifically designed to transmit main shaft power to the corresponding drive shaft. The corresponding ends of the mounting shafts are positioned and mounted on mounting bases or the corresponding machine head housings. The mounting shafts can be a single through shaft that mounts all transmission wheels to drive all first embroidery machine heads and all winding embroidery machine heads; or they can be several short shafts that mount the transmission wheels of the first transmission structure corresponding to each first embroidery machine head, and several short shafts that mount the transmission wheels of the second transmission structure corresponding to each winding embroidery machine head; or they can be several short shafts that mount any number of machine head transmission wheels, and these short shafts can be concentric or non-concentric.

[0029] In this embodiment, to adapt to the structure of the embroidery machine, the first transmission structure 4 includes a first transmission wheel 41 and a first mounting shaft 42 for mounting the first transmission wheel 41, and the second transmission structure 5 includes a second transmission wheel 51 and a second mounting shaft 52 for mounting the second transmission wheel 51. The positions of the first and second mounting shafts can be set according to the transmission requirements, and the corresponding ends of the first and second mounting shafts can be mounted near the machine head housing. The switching structure 6 drives the corresponding transmission wheel to slide or the corresponding mounting shaft to arbitrarily switch the transmission between the first transmission structure 4 and the second transmission structure 5.

[0030] As a switching method, the transmission wheel is slidably mounted on the mounting shaft to facilitate the switching of the drive structure. Preferably, in this embodiment, the mounting shaft is slidably mounted on the mounting base 8 or the corresponding machine head housing, so that the switching structure 6 drives the corresponding mounting shaft to move the corresponding transmission wheel, thereby achieving the drive switching between the first and second drive structures, ultimately enabling the operation of the first and second drive shafts.

[0031] The drive switching between the first and second drive shafts can be achieved by switching structure 6 to drive the first and second transmission wheels to slide. In this embodiment, the drive switching between the first and second drive shafts is achieved by switching structure 6 to drive the mounting shafts of the first transmission structure 4 and the second transmission structure 5 to drive the corresponding transmission wheels to slide.

[0032] The switching structure 6 is equipped with a drive rod 61 for sliding drive force, and the first and second transmission structures are equipped with connecting parts 62 for connecting the drive rod 61. The sliding drive force of the drive rod 61 can be achieved by a linear motor, a pneumatic rod, a hydraulic rod, or a drive motor equipped with a rack and pinion assembly, thereby driving the drive rod 61 to slide back and forth. Of course, other existing technical structures can also be used to drive the drive rod 61 to move.

[0033] In this embodiment, the first drive shaft 1 is provided with a first driven gear 12, the second drive shaft 2 is provided with a second driven gear 22, the first transmission structure 4 is provided with a first transmission gear that cooperates with the first driven gear 12, that is, the first transmission wheel 41 is the first transmission gear; the second transmission structure 5 is provided with a second transmission gear that cooperates with the second driven gear 22, that is, the second transmission wheel 51 is the second transmission gear.

[0034] The main shaft 3 is equipped with mutually cooperating transmission gear sets between itself and the first and second transmission structures. Specifically, the main shaft 3 is equipped with a first drive gear 31 that cooperates with the first transmission gear of the first transmission structure 4, and a second drive gear 32 that cooperates with the second transmission gear of the second transmission structure 5. The main shaft 3 drives the first and second transmission structures through gears, and the first and second transmission structures drive their respective drive shafts through gears.

[0035] See Figure 1-3 The wrapping embroidery head 21 is positioned forward on the main beam 7 relative to the first embroidery head 11. The first embroidery head 11 is mounted on the main beam as a reference. Positioning the wrapping embroidery head 21 forward increases the space between it and the main beam 7, facilitating the use of larger material racks. A mounting base 8 for the wrapping embroidery head 21 is provided between it and the main beam 7. The first transmission structure 4 and / or the second transmission structure 5 are mounted on the mounting base 8. A recess for mounting a drive motor is provided on one side of the casing of the wrapping embroidery head 21, facilitating the installation of a large-capacity motor.

[0036] The connecting component 62 includes a forward / reverse seat 63 that connects the mounting shafts of the first and second transmission structures and a connecting block 64 that connects the drive rod 61. The forward / reverse seat 63 is connected to the connecting block 64 via a slot.

[0037] When using the hybrid embroidery machine of this invention, a type of machine head is pre-driven according to the needs of the pattern. For example, to pre-drive the first embroidery machine head, the drive rod 61 with driving force is controlled to drive the first and second mounting shafts to slide through the connector 62. This causes the first transmission gear on the first mounting shaft 42 to slide between the first driving gear 31 of the main shaft 3 and the first driven gear 12 of the first drive shaft 1. This allows the first transmission gear to transmit the power of the first driving gear 31 to the first driven gear 12, thereby driving the first drive shaft to drive the flat embroidery machine head. When the first and second mounting shafts slide, and the first transmission gear meshes with the first driving gear 31 and the first driven gear 12, the second transmission gear disengages from its position of engagement with the second driving gear 32 and the second driven gear 22, disconnecting the transmission to the second drive shaft 2.

[0038] When the wrap-around embroidery needs to be replaced, the drive rod 61, which has driving force, drives the first and second mounting shafts to slide in opposite directions through the connector 62. This causes the second transmission gear on the second mounting shaft 52 to slide between the second driving gear 32 of the main shaft 3 and the second driven gear 22 of the second drive shaft 2. This allows the second transmission gear to transmit the power of the second driving gear 32 to the second driven gear 22, thereby driving the second drive shaft 2 to operate the wrap-around embroidery machine head. When the first and second mounting shafts slide in opposite directions and the second transmission gear meshes with the second driving gear 32 and the second driven gear 22, the first transmission gear disengages from its position of engagement with the first driving gear and the first driven gear 12, disconnecting the transmission to the first drive shaft 1.

[0039] In this invention, the directional terms front, back, left, and right refer to the side where the operator is located when the embroidery machine is normally placed and used. Front is the side where the operator is located, and back is the side where the operator is located. Left is the left side of the operator, and right is the other side.
