Furthermore, the piece dragging mechanism can be installed on a single gold piece feeding device, a stacked piece feeding device or a multi-gold piece feeding device.

Description

Technical Field

[0001] This invention relates to a large gold sheet dragging mechanism, a sheet feeding device, and a multi-gold sheet feeding device. Background Technology

[0002] In typical sequin embroidery, the sequins are continuously pulled from the sequin tray by the levers of the levers and forks, thus feeding the sequins for embroidery. However, in large sequin embroidery, because the sequins are much larger than ordinary ones, the sequin tray supplying the sequins is quite heavy. The existing lever and fork transmission mechanism is elastically connected. Therefore, when relying solely on the levers and forks to pull the large sequin tray during embroidery, the elastically connected levers and forks struggle. This can easily cause a delay in feeding the large sequins, affecting their feeding process.

[0003] To solve the above problems, a feeding motor is usually installed on the gold sheet tray of the large gold sheet. This structure requires an additional drive motor, which also increases the weight and structure of the gold sheet tray, resulting in higher costs. Summary of the Invention

[0004] To address the problems of difficult or costly feeding of large sequins during embroidery and the complexity of existing structures, this invention provides a simple large sequin dragging mechanism, feeding device, and multi-sequin feeding device.

[0005] The technical solution of the present invention to solve the existing problems is: a large gold sheet dragging mechanism, as an improvement, including a base, a sheet picker that can be oscillatingly mounted on the base, a guide wheel mounted on the base and cooperating with the corresponding part of the base and / or cooperating with the roller to press the gold sheet, the sheet picker having a sheet pick handle that can pick up the gold sheet, and a driving part and / or a driving handle that transmits external power to drive the sheet pick handle to produce a sheet picking action, the guide wheel being a one-way rotating wheel that guides the gold sheet to be transported.

[0006] As a further improvement, the pick-up handle and drive handle are integrated into a lever and rotatably mounted on the base.

[0007] As a further improvement, the guide wheel is slidably mounted on the base, and the guide wheel is provided with an elastic body that drives the guide wheel to press the gold sheet; the roller is a one-way rotating wheel that guides the gold sheet to be transported.

[0008] As a further improvement, an elastic body is provided to drive the pick handle to return to its original position.

[0009] As a further improvement, the wafer picker is positioned upstream of the wafer conveying direction, and the wafer guide wheel is positioned downstream of the wafer picker.

[0010] A single gold sheet or stacked sheet feeding device is provided, which is equipped with any one or any combination of the above-mentioned schemes for large gold sheet dragging mechanism. The feeding device includes a motor mounting plate, a cutting blade assembly, a set of sheet feeders or multiple sets of stacked sheet feeders. Each set of sheet feeders includes a pawl fork, a pawl connecting rod for driving the pawl fork, and a drive motor for driving the pawl and the sheet. As an improvement, the base is mounted on the motor mounting plate, and the driving part and / or the driving handle of the large gold sheet dragging mechanism's sheet picker cooperates with the pawl connecting rod; or the driving part and / or the driving handle of the large gold sheet dragging mechanism's sheet picker cooperates with a swing arm coaxial with the pawl connecting rod.

[0011] A multi-gold wafer feeding device, comprising a large gold wafer dragging mechanism with any one or any combination of the above-mentioned schemes, includes a connecting base, a mounting frame, a slicing assembly, a wafer-pulling drive assembly, and a multi-gold wafer feeding mechanism; the multi-gold wafer feeding mechanism includes at least two sets of wafer feeders arranged side by side, and further includes a switching driver for driving the wafer feeders of the corresponding multi-gold wafer feeding mechanism to slide to the wafer feeding station, and a feed driver for driving the multi-gold wafer assembly to move forward and backward; the wafer-pulling drive assembly includes wafers corresponding to the wafer feeders entering the wafer feeding station. As an improvement, the large gold sheet dragging mechanism is mounted on the multi-gold sheet feeding mechanism and cooperates with the corresponding large gold sheet feeder of the multi-gold sheet feeding mechanism. A second drive structure is provided between the drive part and / or the drive handle and the transmission arm, which can drive the large gold sheet feeder of the multi-gold sheet feeding mechanism into the feeding position by switching the driver, and cooperates with the drive part and / or the drive handle.

[0012] As a further improvement, it also includes a film feeding bracket installed on the end seat of the multi-film feeding mechanism; the second driving structure is a protrusion set on the transmission arm that can cooperate with the driving part and / or the driving handle.

[0013] As a further improvement, the protrusion is disposed on the corresponding side of the transmission arm, the side being the direction in which the feeder slides; the protrusion is a cylindrical protrusion; and a bearing is provided on the protrusion.

[0014] As a further improvement, the corresponding large gold sheet feeder of the multi-gold sheet feeding mechanism is set on one side, both sides, or near one side or both sides of the multi-gold sheet feeding mechanism; the large gold sheet dragging mechanism corresponds one-to-one with the corresponding large gold sheet feeder.

[0015] Compared with existing technologies, this invention features a movable picker on a base and a guide wheel that cooperates with the base and / or with the roller to press the gold sheet. The picker includes a pick handle for picking up the gold sheet and a drive part and / or drive handle that transmits external power to drive the pick handle to pick up the gold sheet. During the transport of large gold sheets, the drive part and / or drive handle, through external force input, can actively drive the pick handle to drag the large gold sheet during transport, thus facilitating the picking and dragging of the large gold sheet from the sheet tray. After passing through the one-way rotating guide wheel, the large gold sheet acts as a check wheel, facilitating its transport. Its advantages are that this invention has a simple structure, can solve the existing problem of large gold sheet feeding relatively inexpensively, and is beneficial for the transport of large gold sheets.

[0016] Furthermore, the dragging mechanism can be installed on a single gold sheet, stacked gold sheet feeding device, or multi-gold sheet feeding device. Power-generating components on the single gold sheet, stacked gold sheet, or multi-gold sheet feeding device, such as a lever connecting rod, a drive swing rod, or a transmission arm, can directly drive the driving part and / or the drive handle, thereby driving the picker handle to drag the large gold sheet during the gold sheet conveying process.

[0026] Large gold sheet dragging mechanism 1, sheet feeding bracket 10, base 11, guide wheel 12, first elastic body 13, second elastic body 14, roller 15, sheet picker 2, sheet pick handle 21, drive handle 22, connecting seat 3, mounting bracket 31, feed driver 32, slicing assembly 33, first drive structure 4, first drive motor 41, drive swing arm 42, curved arm connecting rod 43, second drive structure 5, slicing drive assembly 6, transmission arm 61, drive arm 62, protrusion 51, multi-gold sheet feeding mechanism 7, sheet feeder 71, slicing connecting rod assembly 72, end seat 73, switching driver 8, sheet tray 9, gold sheet 91.

[0027] See Figure 1-4 A large gold sheet dragging mechanism 1 includes a base 11 for mounting and positioning various components, a sheet picker 2 that can be oscillatingly mounted on the base 11, and a guide wheel 12 mounted on the base 11 and cooperating with the corresponding part of the base 11 and / or cooperating with the roller 15 to press the gold sheet. The sheet picker 2 is provided with a sheet picker handle 21 that can pick up the gold sheet, and a driving part and / or a driving handle 22 that transmits external power to drive the sheet picker handle 21 to produce a sheet picking action. The guide wheel 12 is a one-way rotating wheel that guides the gold sheet to be transported.

[0028] The driving part and / or driving handle of the picker 2 can be located on the picker handle 21 at a corresponding position, or they can be set separately. For example, the driving part can be located on the picker handle 21, and the picker handle 21 is driven by an external force. The driving handle 22 can be set separately, and the picker handle 21 is driven by meshing teeth. The specific structure of the driving part and / or driving handle is determined by facilitating the transmission of external force. To simplify the structure, this embodiment uses the driving handle 22 as an example. The picker handle 21 and driving handle 22 are integrally formed, constituting a lever, and are rotatably mounted on the base 11. The driving handle 22 can be located on the same side or opposite side of the swing rotation point as the picker handle 21. In this embodiment, the driving handle 22 and the picker handle 21 are located on opposite sides of the swing rotation point, with the driving handle 22 on one side and the picker handle 21 on the other side, so that when the driving handle 22 is connected to an external force, it will not affect the picker action of the picker handle 21.

[0029] The drive unit or drive handle 22 can be driven by a separate power source or other power components of the existing film feeding device. For example, a drive motor with a swing arm can be provided to drive the drive handle 22 separately, or a reciprocating component of the existing film feeding device, such as a swing rod, connecting rod, or transmission arm, can be used.

[0030] The guide wheel 12 is slidably mounted on the base 1. The guide wheel 12 is equipped with an elastic body that drives and presses the gold sheet against it. This elastic body is designated as the first elastic body 13. By driving the unidirectional rotating guide wheel 12 to clamp the gold sheet, the elastic body effectively prevents backflow. A pair of first elastic bodies 13 can be provided, respectively located on both sides of the guide wheel 12. The roller 15 can also be configured as a unidirectional rotating wheel guiding the gold sheet. Large gold sheets can pass between the guide wheel 12 and the roller 15, achieving unidirectional backflow prevention during feeding. The unidirectional rotation of the guide wheel 12 and the roller 15 can be replaced by a unidirectional bearing or other unidirectional backflow prevention structure. The guide wheel 12 is slidably mounted on the base 1 via the mounting shaft. A sliding groove that cooperates with the mounting shaft can be provided at a corresponding position on the base 1. One end of the first elastic body 13 is suspended on the mounting shaft of the guide wheel 12, and the other end is suspended on the base 1 to pull the guide wheel 12, so that the guide wheel 12 can elastically cooperate with the roller 15, thereby clamping the large gold sheet.

[0031] To facilitate the control of the picker handle 21, the picker 2 is provided with a resetting elastic body that drives the picker handle 21. Specifically, a resetting elastic body can be provided in the drive handle 22 or / and the picker handle 21. The resetting elastic body is referred to as the second elastic body 14.

[0032] In practical use, the picker 2 is positioned upstream of the gold sheet conveying direction, and the guide wheel 12 is positioned downstream of the picker 2.

[0033] When embroidering large gold pieces, the large gold piece dragging mechanism 1 can be used in conjunction with an existing feeding device that needs to transport large gold pieces. Specifically, the base 11 can be installed on the large gold piece transport path between the piece tray 9 and the feeding device, in a position that facilitates picking up the gold piece. The gold piece can be routed around the picking handle 21, and then pass between the guide wheel 12 and the corresponding part of the base 11, or between the guide wheel 12 and the roller 13, so that the picking handle 21 can easily pick up the gold piece 91 when it moves. The gold piece is located on the route of the large gold piece dragging mechanism 1, specifically to facilitate the picking handle 21 to pick up and drag the gold piece 91 on the piece tray 9. Since the guide wheel 12 is a one-way rotating wheel, the drive handle 22 receives external force and drives the picking handle 21 to swing. The swinging picking handle 21 can move the large gold piece that is under tension on the picking handle 21. After the picker handle 21 picks up the gold sheet, it will drag the gold sheet out of the plate tray, thereby reducing the resistance of the subsequent plate feeding device and making the plate feeding device transport large gold sheets more smoothly.

[0034] The large gold sheet dragging mechanism 1 of the present invention can be installed on an existing single gold sheet feeding device or a stacked gold sheet feeding device. A feeding device (not shown in the figure) is provided with the large gold sheet dragging mechanism 1 installed in any of the above-mentioned schemes or combinations thereof. The feeding device includes a motor mounting plate, a cutting blade assembly, a set of feeders or multiple sets of stacked gold sheet feeders. Each set of feeders includes a shovel fork, a shovel connecting rod for driving the shovel fork, a drive motor for driving the shovel and the slice, and a base plate with a slice slot. The base 11 of the large gold sheet dragging mechanism 1 can be directly installed or mounted on the motor mounting plate via a bracket. The drive handle 22 of the picker 2 of the large gold sheet dragging mechanism 1 cooperates with the shovel connecting rod; or the drive handle 22 of the picker 2 of the large gold sheet dragging mechanism 1 cooperates with a swing arm coaxial with the shovel connecting rod. The swing arm coaxial with the shovel connecting rod of the single gold sheet or stacked gold sheet can cooperate with the drive handle 22 to drive the picker handle 21. The aforementioned feeding devices for single or stacked gold sheets can all adopt existing technological structures.

[0035] See Figure 1-9 A multi-gold sheet feeding device, comprising a large gold sheet dragging mechanism 1 of any one or any combination of the above-mentioned schemes, including a connecting base 3, a mounting frame 31, a slicing assembly 33, a slicing drive assembly 6, and a multi-gold sheet feeding mechanism 7; the multi-gold sheet feeding mechanism 7 includes at least two sets of sheet feeders 71 arranged side by side, and also includes a switching driver 8 for driving the sheet feeder 71 of the corresponding multi-gold sheet feeding mechanism 7 to slide to the feeding station, and a feed driver 32 for driving the multi-gold sheet assembly to move forward and backward; the slicing drive assembly 6 includes a mechanism for driving the sheet feeder 71 to move forward and backward to the feeding station. The drive arm 62 is engaged with the paddle linkage assembly 72, the first drive structure 4 for power output, and the transmission arm 61 that transmits power between the drive arm 62 and the first drive structure 4. The large gold sheet dragging mechanism 1 is mounted on the multi-gold sheet feeding mechanism 7 and cooperates with the corresponding large gold sheet feeder 71 of the multi-gold sheet feeding mechanism 7. A second drive structure 5 is provided between the drive handle 22 and the transmission arm 61. The second drive structure 5 can drive the large gold sheet feeder 71 of the multi-gold sheet feeding mechanism 7 into the feeding position with the switching driver 8, and cooperate with the drive handle 22 to drive the drive arm 22 to move.

[0036] Connector 3 is used to connect the entire device to the needle bar holder or other fixed frame.

[0037] Mounting bracket 31 is connected to connecting seat 3 via feed driver 32, and mounting bracket 31 is connected to multi-gold sheet feeding mechanism 7 via switching driver 8.

[0038] A paddle shifter drive assembly 6 is mounted on a mounting bracket 31. The first drive structure 4 of the paddle shifter drive assembly 6 includes a first drive motor 41, a drive swing arm 42 mounted on the first drive motor 41, and a curved arm connecting rod 43 cooperating with the drive swing arm 42. The first drive motor 41 is mounted on the mounting bracket 31. The curved arm connecting rod 43 is rotatably mounted on the mounting bracket 31, located on the side where the transmission arm 61 is located. One arm of the curved arm connecting rod 43 is rotatably connected to the corresponding end of the transmission arm 61, and the other end of the transmission arm 61 is rotatably connected to the drive arm 62. The other arm of the curved arm connecting rod 43 cooperates with the drive swing arm 42 and can receive power from the drive swing arm 42.

[0039] The slicing assembly 33 has its cutter mounted on the corresponding side of the mounting bracket 31 via a cutter holder, and can be located on the opposite side of the drive arm 61. The cutter of the cutter assembly is positioned at the wafer feeding station to cut the gold wafers conveyed by the wafer feeder 71 at the wafer feeding station. The slicing assembly 33 and the paddle drive assembly 6 share the same first drive motor 41. This drive motor rotates towards the corresponding cutter side, driving the cutter to slice the wafer through the drive assembly of the slicing assembly 33, and rotates towards the drive arm 61 on the other side, driving the drive arm 61 to move. The drive arm 61, through the drive arm 62, drives the paddle linkage assembly 72 to produce a paddle action.

[0040] The multi-plate feeding mechanism 7 includes multiple sets of plate feeders 71 arranged side by side, a base plate with a plate slot corresponding to the plate feeder 71, a connecting base plate, and end seats 73 on both sides of the plate feeder. The plate feeding mechanism 72 of each set of plate feeders 71 includes a plate fork and a plate connecting rod that drives the plate fork. The plate connecting rod is provided with a connecting arm that cooperates with the drive arm 62. The drive arm 62 cooperates with the connecting arm of the corresponding plate feeder 71 entering the plate feeding station, and then drives the plate fork to move the plate through the plate connecting rod.

[0041] The switching driver 8 is typically installed between the mounting bracket 31 and the multi-plate feeding mechanism 7, connecting and driving the multi-plate feeding mechanism 7 to slide relative to the mounting bracket 31, so as to move the corresponding feeder of the multi-plate feeding mechanism 7 to the feeding station for feeding. The switching driver 8 includes a lead screw and slider assembly, a slide rail assembly, and a drive motor that connect the mounting bracket 31 and the multi-plate feeding mechanism 7.

[0042] The feed driver 32 is positioned between the connecting mounting bracket 31 and the connecting seat 3, and includes a slide rail assembly connecting the mounting bracket 31 and the connecting seat 3, a drive motor, and a first swing assembly between the drive motor of the feed driver 32 and the mounting bracket 31 to drive the mounting bracket 31 to slide forward and backward, thereby driving the multi-sheet feeding mechanism 7 to move forward and backward. The first swing assembly includes a first swing rod mounted on the drive motor of the feed driver 32, a swing shaft mounted on the first swing rod to push the mounting bracket 31 to slide, and a return spring for the mounting bracket 31. A bearing may be installed on the swing shaft. Of course, the feed driver 32 can also be driven by a lead screw and slider assembly.

[0043] The connecting seat 3, mounting frame 31, slicing assembly 33, slicing drive assembly 6, and multi-gold sheet feeding mechanism 7 of the above-mentioned multi-gold sheet feeding device can all adopt existing technical structures.

[0044] It also includes a film feeding bracket 10 installed on the end seat 73 of the multi-film feeding mechanism 7; the second driving structure 5 is a protrusion 51 set on the transmission arm 61 that can cooperate with the driving handle 22.

[0045] Of course, the second driving structure 5 can also be a sliding insert and a sliding shaft that slide within the sliding insert, which are disposed on the driving handle 22 and the transmission arm 61. The transmission arm 61 drives the driving handle 22 to reciprocate through the cooperation of the sliding insert and the sliding shaft. The sliding insert can be disposed on the driving handle 22, and the sliding shaft can be disposed on the transmission arm 61 in a manner similar to a protrusion 51. The sliding insert and the handle are provided with sliding grooves, and the sliding shaft rotates and slides within the sliding grooves.

[0046] When the multi-plate feeding mechanism 7 needs to transport large gold plates, the large gold plate feeder is moved to the feeding station by the switching driver 8. The drive arm 22 of the large gold plate dragging mechanism 1 then enters a position that can cooperate with the protrusion 51. The transmission arm 61 drives the paddle linkage assembly 72 of the large gold plate feeder located at the feeding station to paddle and feed the gold plates. The protrusion 51 on the transmission arm 61 pushes the drive handle 22 to move. The drive handle 22, which forms a lever with the pick-up handle 21, drives the pick-up handle 21 to swing, thereby dragging the large gold plate located at the pick-up handle 21. The tension of the large gold plate located on the large gold plate feeding path changes. Since the lower side of the large gold plate is driven and prevented from returning by the guide wheel 12, the large gold plate will be dragged out from the plate tray 9, thereby supplying the large gold plate feeding.

[0047] The protrusion 51 is disposed on the corresponding side of the transmission arm 61, and the side is the direction in which the sheet feeder slides; the side placement helps to make the combination of the large sheet dragging mechanism 1 and the multi-sheet feeding device more compact. The protrusion 51 is a cylindrical protrusion; the protrusion 51 is provided with a bearing.

[0048] To facilitate wafer replacement, the corresponding large wafer feeder 71 of the multi-wafer feeding mechanism 7 is preferably disposed on one side, both sides, or near one side or both sides of the multi-wafer feeding mechanism 7; the large wafer dragging mechanism 1 corresponds one-to-one with the corresponding large wafer feeder 71.

[0049] Since the drive arm 61 is typically fixed in position on the mounting bracket 31 to drive the corresponding sheet feeder's lever assembly 72 at the sheet feeding station to generate a sheet feeding action, the sheet feeder 71 and the large gold sheet dragging mechanism 1 need to slide relative to the drive arm 61, and a second drive structure 5 is required between the drive arm 61 and the large gold sheet feeding mechanism. Therefore, by placing the corresponding large gold sheet feeder 71 on one side, both sides, or near one side or both sides of the multi-gold sheet feeding mechanism 7, when conveying other conventional gold sheets during the reciprocating movement of the multi-gold sheet feeding mechanism 7, the engagement between the protrusion 51 on the drive arm 61 and the drive handle 22 can be avoided as much as possible. This simplifies the structure of the second drive structure 5.

[0050] Of course, the protrusion 51 can also be set on the rear end face of the transmission arm 61, and can cooperate with the drive handle 22 that enters the feeding position. Any one of the feeders of the multi-plate feeding mechanism 7 of this structure can be set as a large plate feeder 71.

[0051] See Figure 7 To facilitate use and simplify the second drive structure 5, in this embodiment, the corresponding large gold sheet feeder 71 of the multi-gold sheet feeding mechanism 7 is located on one side and both sides of the multi-gold sheet feeding mechanism 7. When large gold sheets need to be transported, the large feeder located on the side of the multi-gold sheet feeding mechanism 7 is moved to the feeding position by switching the driver 8, so that the corresponding protrusion 51 on the transmission arm 61 engages with the drive handle 22. The sliding of the drive handle 22 with the feeder does not affect the feeding of other conventional gold sheets.
