[0006] In the above-mentioned embroidery machine, the lifting mechanism includes a transmission assembly and a drive assembly. The transmission assembly is arranged in the guide tube and connected to the table. The drive assembly is arranged on the frame outside the guide tube and connected to the transmission assembly to drive the table to rise and fall through the transmission assembly.

[0007] In the above-mentioned embroidery machine, the transmission assembly includes a screw rod rotatably connected in the guide tube and a screw rod nut sleeved on the screw rod, and the screw rod nut is locked with the table plate to be linked with the table plate.

[0008] In the above-mentioned embroidery machine, the table includes a plate body and two square tubes arranged parallel to the bottom of the plate body, the screw nut includes an upper nut and a lower nut located below the upper nut, the upper nut is connected to the square tube close to the guide tube side, and the lower nut is connected to the square tube away from the guide tube side through a support frame.

[0009] In the above-mentioned embroidery machine, an adjusting screw is connected between the plate body and the square tube at a side away from the guide tube.

[0010] In the above-mentioned embroidery machine, the driving assembly includes a horizontally arranged driving shaft and a driving motor that drives the driving shaft to rotate. The driving shaft is provided with an active bevel gear, and the bottom of the screw rod is provided with a driven bevel gear.

[0012] In the above-mentioned embroidery machine, a belt transmission assembly is connected between the output shaft of the driving motor and the driving shaft, and the output shaft of the driving motor drives the driving shaft to rotate through the belt transmission assembly.

[0013] The beneficial effects of the utility model are:

[0014] An embroidery machine includes a frame and a table. The frame is provided with a lifting device for driving the table to rise and fall. The lifting device includes a guide tube vertically arranged on one side of the table and a lifting mechanism arranged in the guide tube. The guide tube is provided with a longitudinally extending sliding hole. The lifting mechanism passes through the sliding hole and is connected to the table to drive the table to rise and fall. The technical solution has the following technical effects:

[0015] The utility model sets a lifting device connected with a table on a frame, so that the lifting device can drive the table to rise or fall. When the embroidery machine needs to switch from a flat embroidery mode to a garment embroidery mode or a cap embroidery mode, the staff lowers the table through the lifting device, so as to avoid the garment embroidery mechanism or the cap embroidery mechanism to be installed on the frame, so as to provide sufficient installation space for the garment embroidery mechanism or the cap embroidery mechanism, and the staff does not need to manually remove the heavy table, so that the operation is simpler and more convenient, and the switching efficiency is improved. By setting the lifting device as a structure of a guide tube and a lifting mechanism located in the guide tube, and setting a sliding hole for the lifting mechanism to slide on the side wall of the guide tube, the lifting mechanism partially extends out of the guide tube through the sliding hole to drive the table to rise and fall, and partially hides in the guide tube. The guide tube protects the lifting mechanism, prolongs the service life of the lifting mechanism, and makes the appearance of the guide device more concise and beautiful. At the same time, the sliding hole can also limit the lifting mechanism passing through it, so that the lifting mechanism can only drive the table to move along the sliding direction, that is, the table can only be lifted in the vertical direction, and the table is prevented from moving in other directions, so that the table is more stable.

[0016] The side of the table is provided with an avoidance notch, and the side of the guide tube is embedded in the avoidance notch to guide the table. The avoidance notch limits the table in the horizontal direction and guides it in the vertical direction, so that the avoidance notch on the table can only slide up and down along the guide tube, ensuring the stable movement of the table in the vertical direction and preventing the table from shaking horizontally.

[0017] The lifting mechanism includes a transmission assembly and a drive assembly. The transmission assembly is arranged in the guide tube and connected to the table. The drive assembly is arranged on the frame outside the guide tube and connected to the transmission assembly, so as to drive the table to rise and fall through the transmission assembly. By arranging the transmission assembly in the guide tube and arranging the drive assembly outside the guide tube, the guide tube does not need to accommodate the large-volume drive assembly, so the guide tube only needs a small inner diameter to accommodate the transmission assembly, reducing the space occupied by the guide tube and facilitating the maintenance of the drive assembly.

[0018] The transmission assembly includes a screw rod rotatably connected in the guide tube and a screw nut sleeved on the screw rod, and the screw nut is locked with the table plate to be linked with the table plate. By setting the transmission assembly into a structure in which the screw nut and the screw rod cooperate, the transmission assembly does not need to be extended and retracted in the guide tube, and the screw nut can be driven to move up and down by the rotation of the screw rod, thereby driving the table plate to rise and fall, and the operation is stable and reliable.

[0019] The table includes a plate body and two square tubes arranged parallel to the bottom of the plate body. The screw nut includes an upper nut and a lower nut located below the upper nut. The upper nut is connected to the square tube on the side close to the guide tube, and the lower nut is connected to the square tube on the side away from the guide tube through a support frame. By arranging the upper nut and the lower nut on the screw rod to support both sides of the table respectively, the transmission component has a better supporting effect on the table, ensuring the level of the table, and preventing the table from tilting and affecting the operation of the embroidery machine.

[0020] An adjusting screw is connected between the plate body and the square tube on the side away from the guide tube. While connecting and fixing the plate body and the square tube, the adjusting screw can adjust the distance between the plate body and the square tube, thereby adjusting the height of the plate body away from the guide tube to ensure the level of the plate body.

[0021] The driving assembly includes a horizontally arranged driving shaft and a driving motor for driving the driving shaft to rotate. The driving shaft is provided with an active bevel gear, and the bottom of the screw rod is provided with a driven bevel gear. The active bevel gear meshes with the driven bevel gear to make the driving shaft and the screw rod move in conjunction. The arrangement of the driven bevel gear at the bottom of the screw rod and the driving shaft with the active bevel gear on one side of the screw rod enables the driving assembly and the transmission assembly to change the transmission direction through the meshing of the active bevel gear and the driven bevel gear, without the need to arrange the driving assembly below the transmission assembly, thereby shortening the overall height of the lifting device and making more flexible use of the rack space.

[0022] There are multiple transmission components, and the driving shaft is provided with active bevel gears corresponding to the multiple transmission components one by one, so as to drive multiple screw rods to rotate at the same time, so that a single driving shaft can drive multiple screw rods to rotate at the same time, simplifying the structural complexity of the lifting device and reducing production and processing costs.

[0023] A belt transmission assembly is connected between the output shaft of the drive motor and the drive shaft, and the output shaft of the drive motor drives the drive shaft to rotate through the belt transmission assembly. The arrangement of the belt transmission assembly makes it possible to achieve the connection and transmission between the output shaft of the drive motor and the drive shaft without arranging the drive motor at the end of the drive shaft, and the drive motor can be installed at a suitable position of the frame as required, making the installation operation more flexible.

[0024] The features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The utility model proposes an embroidery machine, including a frame and a table. The frame is provided with a lifting device for driving the table to rise and fall. The lifting device includes a guide tube vertically arranged on one side of the table and a lifting mechanism arranged in the guide tube. The guide tube is provided with a longitudinally extending sliding hole. The lifting mechanism passes through the sliding hole and is connected to the table to drive the table to rise and fall. The utility model sets a lifting device connected to the table on the frame, so that the lifting device can drive the table to rise or fall. When the embroidery machine needs to switch from a mode such as flat embroidery to a mode such as garment embroidery or cap embroidery, the staff lowers the table through the lifting device to avoid the garment embroidery mechanism or cap embroidery mechanism to be installed on the frame, so as to provide sufficient installation space for the garment embroidery mechanism or cap embroidery mechanism. The staff does not need to manually remove the heavy table, so the operation is simpler and more convenient, and the switching efficiency is improved. By configuring the lifting device to be a structure of a guide tube and a lifting mechanism inside the guide tube, and providing a sliding hole on the side wall of the guide tube for the lifting mechanism to slide, the lifting mechanism partially extends out of the guide tube through the sliding hole to drive the table to be lifted and lowered, and partially is hidden in the guide tube. The guide tube protects the lifting mechanism, thereby extending the service life of the lifting mechanism and making the appearance of the guide device more concise and beautiful. At the same time, the sliding hole can also limit the lifting mechanism passing through it, so that the lifting mechanism can only drive the table to move along the sliding direction, that is, the table can only be lifted and lowered in the vertical direction, avoiding the table to move in other directions, making the table more stable.

[0042] Example:

[0043] An embroidery machine, such as Figures 1 to 5 As shown, it includes a frame 100 and a table 200. A lifting device is provided on the frame 100, and the lifting device is used to drive the table 200 to rise or fall on one side of the frame 100. The lifting device includes a guide tube 300 and a lifting mechanism 400. The guide tube 300 is a hollow structure and is arranged on one side of the table 200. The lifting mechanism 400 is arranged inside the guide tube 300. A sliding hole 310 for connecting the inner and outer sides of the guide tube 300 is provided on the side wall of the guide tube 300. The sliding hole 310 extends longitudinally on the side wall of the guide tube 300. The lifting mechanism 400 part in the guide tube 300 passes through the sliding hole 310 and is connected to the table 200 on one side of the guide tube 300. The part of the lifting mechanism 400 that passes through the sliding hole 310 slides up and down along the sliding hole 310 to realize the control of the lifting mechanism 400 on the rise or fall of the table 200.

[0044] The utility model arranges a lifting device connected to the table 200 on the frame 100, so that the lifting device can drive the table 200 to rise or fall. When the embroidery machine needs to switch from a mode such as flat embroidery to a mode such as garment embroidery or cap embroidery, the staff can lower the table 200 through the lifting device to avoid the garment embroidery mechanism or cap embroidery mechanism to be installed on the frame 100, so as to provide sufficient installation space for the garment embroidery mechanism or cap embroidery mechanism, and the staff does not need to manually remove the heavy table 200, so the operation is simpler and more convenient, and the switching efficiency is improved. By configuring the lifting device to be a structure composed of a guide tube 300 and a lifting mechanism 400 located in the guide tube 300, and providing a sliding hole 310 on the side wall of the guide tube 300 for the lifting mechanism 400 to slide, the lifting mechanism 400 is partially extended out of the guide tube 300 through the sliding hole 310 to drive the table 200 to be lifted and lowered, and is partially hidden in the guide tube 300. The guide tube 300 protects the lifting mechanism 400, thereby extending the service life of the lifting mechanism 400 and making the appearance of the guide device more concise and beautiful. At the same time, the sliding hole 310 can also limit the lifting mechanism 400 passing through it, so that the lifting mechanism 400 can only drive the table 200 to move along the sliding direction, that is, the table 200 can only be lifted and lowered in the vertical direction, avoiding the table 200 from moving in other directions, making the table 200 more stable.

[0045] like Figure 4 As shown, a relief recess 211 is provided on the side of the table 200 facing the frame 100 to avoid the guide tube 300. Figure 1 As shown, the side of the guide tube 300 is embedded in the avoidance recess 211, and the shape of the avoidance recess 211 cooperates with the outer wall of the guide tube 300, so that the outer wall of the guide tube 300 fits with the inner wall of the avoidance recess 211, so as to limit the table 200 in the horizontal direction and guide it in the vertical direction, so that the avoidance recess 211 on the table 200 can only slide up and down along the guide tube 300, thereby ensuring the stable movement of the table 200 in the vertical direction and preventing the table 200 from shaking horizontally.

[0046] like Figure 1 and Figure 2As shown, in this embodiment, the lifting mechanism 400 includes a transmission assembly 410 and a drive assembly 420. The transmission assembly 410 is arranged in the guide tube 300. The transmission assembly 410 partially passes through the slide hole 310 and is connected to the table 200. The drive assembly 420 is arranged on the frame 100 outside the guide tube 300. The drive assembly 420 is connected to the transmission assembly 410. The drive assembly 420 drives the table 200 to rise and fall through the transmission assembly 410. By arranging the transmission assembly 410 in the guide tube 300 and arranging the drive assembly 420 outside the guide tube 300, the guide tube 300 does not need to accommodate the larger drive assembly 420. The guide tube 300 only needs a smaller inner diameter to accommodate the transmission assembly 410, thereby reducing the space occupied by the guide tube 300 and facilitating the maintenance of the drive assembly 420. Preferably, as Figure 5 As shown, the transmission assembly 410 includes a screw rod 411 and a screw rod nut 412, an upper bearing seat 320 and a lower bearing seat 330 are provided in the guide tube 300, the upper end of the screw rod 411 is rotatably connected to the upper bearing seat 320 through a bearing, and the lower end of the screw rod 411 is rotatably connected to the lower bearing seat 330 through a bearing, the screw rod nut 412 is sleeved on the screw rod 411 and threadedly connected to the screw rod 411, and a screw is provided on the screw rod nut 412, and the screw passes through the sliding hole 310 and is locked with the table plate 200. By configuring the transmission assembly 410 to be a structure in which the lead screw nut 412 and the lead screw 411 cooperate, the transmission assembly 410 does not need to be extended or retracted in the guide tube 300. The lead screw nut 412 can be driven to move up and down by the rotation of the lead screw 411, thereby driving the lifting and lowering of the table 200. The outer wall of the lead screw nut 412 can fit with the inner wall of the guide tube 300, so that the inner wall of the guide tube 300 can support the side of the lead screw nut 412, share the force of the table 200 exerted on the lead screw nut 412, avoid excessive force on one side of the lead screw nut 412, and squeeze the lead screw 411 and cause wear. The operation is stable and reliable, and the service life of the lead screw 411 and the lead screw nut 412 is extended.

[0047] The table 200 includes a plate body 210, two strip-shaped square tubes and a triangular support frame 240. The two square tubes are arranged in parallel at the bottom of the plate body 210 and locked with the plate body 210. The two square tubes are respectively a first square tube 220 and a second square tube 230. The first square tube 220 extends along a side of the table 200 close to the frame 100, and the second square tube 230 extends along a side of the table 200 away from the frame 100. The support frame 240 is located between the first square tube 220 and the second square tube 230. 30, and locked with the second square tube 230, the screw nut 412 includes an upper nut 4121 and a lower nut 4122, the upper nut 4121 and the lower nut 4122 are separately arranged, and the two are respectively sleeved on the same screw 411, the upper nut 4121 is located above the lower nut 4122, the upper nut 4121 is locked with the first square tube 220, and the lower nut 4122 is locked with the support frame 240, thereby realizing the connection between the lower nut 4122 and the second square tube 230. Of course, in order to enhance the stability of the connection between the support frame 240 and the table, the support frame 240 can also be locked with the first square tube 220. By arranging the upper nut 4121 and the lower nut 4122 on the screw 411 to support the two sides of the table 200 respectively, the transmission assembly 410 has a better supporting effect on the table 200, ensuring the level of the table 200, and preventing the table 200 from tilting and affecting the operation of the embroidery machine. Preferably, an adjusting screw 231 is connected between the plate body 210 and the second square tube 230. While connecting and fixing the plate body 210 and the second square tube 230, the adjusting screw 231 can adjust the distance between the plate body 210 and the second square tube 230, thereby adjusting the height of the side of the plate body 210 away from the guide tube 300 to ensure that the plate body 210 is level.

[0048] like Figure 2 As shown, in this embodiment, the driving assembly 420 includes a driving shaft 421 and a driving motor 422. The driving shaft 421 is horizontally arranged. The driving motor 422 is connected to the driving shaft 421 to drive the driving shaft 421 to rotate. An active bevel gear 4211 linked to the driving shaft 421 is provided on the driving shaft 421. The bottom end of the screw rod 411 passing through the lower bearing seat 330 is provided with a driven bevel gear 4111 linked to the screw rod 411. The active bevel gear 4211 is meshed with the driven bevel gear 4111, so that the driving shaft 421 and the screw rod 4 11 are linked by the meshing active bevel gear 4211 and the driven bevel gear 4111. The driven bevel gear 4111 at the bottom of the screw rod 411 and the driving shaft 421 with the active bevel gear 4211 on one side of the screw rod 411 are arranged, so that the driving component 420 and the transmission component 410 can change the transmission direction through the meshing of the active bevel gear 4211 and the driven bevel gear 4111. There is no need to arrange the driving component 420 below the transmission component 410, which shortens the overall height of the lifting device and makes more flexible use of the space of the frame 100.

[0049] In this embodiment, there are multiple transmission components 410, and the multiple transmission components 410 are arranged at equal intervals and connected to the table 200 to jointly support the table 200, so that the table 200 is more stable. A plurality of active bevel gears 4211 are provided on the driving shaft 421, and the multiple active bevel gears 4211 correspond to each transmission component 410 one by one, so as to realize the joint driving of multiple screw rods 411 by a single driving motor 422 and a driving shaft 421, so that a single driving shaft 421 drives multiple screw rods 411 to rotate at the same time, thereby simplifying the structural complexity of the lifting device and reducing the production and processing costs.

[0050] A belt transmission assembly 423 is connected between the output shaft of the driving motor 422 and the driving shaft 421. The belt transmission assembly 423 includes a driving wheel 4231, a driven wheel 4232 and a belt 4233. The driving wheel 4231 is sleeved on the output shaft of the driving motor 422 and is linked to the output shaft of the driving motor 422. The driven wheel 4232 is sleeved on the driving shaft 421 and is linked to the driving shaft 421. The belt 4233 is used to connect the driving wheel 4231 and the driven wheel 4232 to achieve the common rotation between the driving wheel 4231 and the driven wheel 4232. When the output shaft of the driving motor 422 rotates, the driving wheel 4231 rotates together with the output shaft of the driving motor 422 to drive the belt 4233 to transmit between the driving wheel 4231 and the driven wheel 4232, so that the driven wheel 4232 drives the driving shaft 421 to rotate to achieve transmission. The setting of the belt drive assembly 423 makes it possible to achieve the connection and transmission between the output shaft of the drive motor 422 and the drive shaft 421 without setting the drive motor 422 at the end of the drive shaft 421. The drive motor 422 can be installed at a suitable position of the frame 100 as needed, and the installation operation is more flexible.
