Description

Technical Field

[0001] This utility model generally relates to the field of computerized embroidery machine technology, and more particularly to a backpack structure and a frame for a computerized embroidery machine. Background Technology

[0002] The stability of the computerized embroidery machine frame is a key factor affecting the quality of the embroidery, and the frame's backpack structure plays a crucial role in this stability. It should be noted that computerized embroidery machines are transported in shipping containers, which have standard dimensions; therefore, the overall width of the computerized embroidery machine is constrained by the width of the shipping container.

[0003] With the increased length of the computerized embroidery machine frame and the increased rotational speed of the upper shaft, the stability of the backpack structure becomes particularly important. To ensure this stability, the backpack's structural dimensions can be increased. However, this increases the difficulty of loading the computerized embroidery machine into a shipping container. Utility Model Content

[0004] This utility model provides a backpack structure, which is installed on the frame of a computerized embroidery machine, and includes:

[0005] The body and the reinforcing member are included. The body includes a horizontal section and a vertical section. The reinforcing member is detachably connected to the horizontal section and the vertical section.

[0006] As one possible implementation, the reinforcing member is at least disposed on one side of the body in a first direction, which is perpendicular to the transverse segment and the vertical segment, or...

[0007] The reinforcing member is disposed on the side of the lower frame of the transverse section facing away from the frame and on the side of the vertical section facing away from the lower frame.

[0008] As one possible implementation, the reinforcing member includes a first reinforcing beam, which comprises a transverse portion and a vertical portion. The first reinforcing beam is disposed on one or both sides of the body in the first direction, and is threadedly connected to the body.

[0009] As an implementation method, the dimension of the vertical portion of the beam in the second direction is greater than the dimension of the vertical segment in the second direction, where the second direction is the direction in which the length of the transverse segment extends; the dimension of the transverse portion of the beam in the second direction is smaller than the dimension of the transverse segment in the second direction.

[0010] As an implementation method, both the transverse portion and the vertical portion of the beam are square tubes. The transverse portion and the vertical portion of the beam include a first tube side and a second tube side arranged opposite to each other. The second tube side is attached to the body. An avoidance hole is provided on the first tube side, and a connecting hole coaxial with the avoidance hole is provided on the second tube side. The size of the avoidance hole is larger than the size of the connecting hole.

[0011] As one possible implementation, the reinforcing member includes a reinforcing plate, which has a horizontal portion and a vertical portion. The reinforcing plate is disposed on both sides of the body in the first direction, and the reinforcing plate is threadedly connected to the body.

[0012] As an alternative implementation, the reinforcing member further includes a second reinforcing beam disposed between the two reinforcing plates, and the second reinforcing beam is threadedly connected to the reinforcing plates.

[0013] As an implementation method, the sum of the dimensions of the second reinforcing beam and the vertical segment in the second direction is equal to the dimension of the vertical portion of the plate in the second direction, where the second direction is the direction in which the length of the transverse segment extends.

[0014] As an alternative implementation, a fourth positioning plate is provided on the surface of the vertical section facing the second reinforcing beam, and the second reinforcing beam is positioned and connected by the fourth positioning plate.

[0015] This utility model also provides a frame for a computerized embroidery machine, including the backpack structure described above.

[0016] In the above-described solution, this application provides a reinforcing member at least on one side of the body in the first direction.

[0017] With an increased frame length and higher upper shaft speed in computerized embroidery machines, reinforcing components can be added to enhance the overall strength and rigidity of the backpack structure, thereby improving its stability and ultimately the stability of the computerized embroidery machine. Furthermore, the reinforcing components are detachable from the main body, allowing the frame to be loaded into containers after the reinforcing components are removed, facilitating the loading, unloading, and transportation of the computerized embroidery machine.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] The frame of a computerized embroidery machine includes a main beam and a lower frame, which are arranged vertically, with the length of the main beam parallel to the length of the lower frame. A backpack structure is located behind both the main beam and the lower frame, connecting them. Multiple backpack structures are arranged sequentially along the length of either the main beam or the lower frame. The backpack structures are welded or threaded to the main beam and to the lower frame, respectively.

[0031] The following is at least in conjunction with the accompanying drawings. Figures 1-5 The structure of the backpack is described in detail:

[0032] The backpack structure includes a body 10 and a reinforcing member. The body 10 includes a horizontal segment 11 and a vertical segment 12; the reinforcing member is detachably connected to the horizontal segment 11 and the vertical segment 12, and the reinforcing member is at least disposed on one side of the body 10 in a first direction, which is perpendicular to the horizontal segment 11 and the vertical segment 12. Alternatively, the reinforcing member is disposed on the lower frame side of the horizontal segment 11 facing away from the frame and on the lower frame side of the vertical segment 12 facing away from the frame.

[0033] In practical applications, considering the increased length of the computerized embroidery machine frame and the increased rotational speed of the upper shaft, the stability of the backpack structure is particularly important. Therefore, reinforcing components are installed to increase the strength and rigidity of the entire backpack structure, thereby improving its stability and further enhancing the stability of the computerized embroidery machine. Simultaneously, the reinforcing components are detachably connected to the main body 10, allowing the frame to be loaded into a container after the reinforcing components are removed, facilitating the loading, unloading, and transportation of the computerized embroidery machine.

[0034] In one specific embodiment, such as Figure 3 and Figure 4 As shown, the reinforcing member includes a first reinforcing beam 40, which includes a transverse portion 41 and a vertical portion 42. The first reinforcing beam 40 is disposed on one or both sides of the body 10 in a first direction, and the first reinforcing beam 40 is threadedly connected to the body 10.

[0035] like Figure 3 and Figure 4 As shown, the first direction is the left-right direction, and the second direction is the front-back direction. The first reinforcing beam 40 can be located on the left side of the body 10, and / or on the right side of the body 10. The first reinforcing beam 40 is a profile, which can be, but is not limited to, square steel, flat steel, and channel steel. The first reinforcing beam 40 can be made of, but is not limited to, carbon steel.

[0036] The first reinforcing beam 40 includes a transverse portion 41 and a vertical portion 42. The transverse portion 41 extends in the front-to-back direction, and the vertical portion 42 extends in the up-down direction. One end of the transverse portion 41 and one end of the vertical portion 42 can be welded together, or they can be threaded together.

[0037] The following embodiment illustrates the welding connection between the transverse portion 41 and the vertical portion 42 of the beam, both of which are square steel:

[0038] like Figure 4 As shown, the body 10 includes a horizontal section 11 and a vertical section 12. Multiple first positioning plates 13 are provided on the horizontal section 11, and the first positioning plates 13 are provided with first threaded holes. Multiple second positioning plates 14 are provided on the vertical section 12, and the second positioning plates 14 are provided with second threaded holes.

[0039] The beam's transverse portion 41 and vertical portion 42 include a first tube side and a second tube side arranged opposite to each other. The second tube side is in contact with the first positioning plate 13 and the second positioning plate 14 on the main body 10. A first clearance hole 411 is provided on the first tube side of the beam's transverse portion 41, and a first connecting hole coaxial with the first clearance hole 411 is provided on the second tube side. The size of the first clearance hole 411 is larger than the size of the first connecting hole. This allows tools to pass through the first clearance hole 411 and connect bolts to the first connecting hole and the first threaded hole. Similarly, a second clearance hole 421 is provided on the first tube side of the beam's vertical portion 42, and a second connecting hole coaxial with the second clearance hole 421 is provided on the second tube side. The size of the second clearance hole 421 is larger than the size of the second connecting hole. This allows tools to pass through the second clearance hole 421 and connect bolts to the second connecting hole and the second threaded hole. This arrangement minimizes bolt length when stably connecting the main body 10 and the first reinforcing beam 40, thereby reducing the possibility of bolt shear failure due to lateral loads. The first positioning plate 13 and the second positioning plate 14 can be used to accurately position and install the first reinforcing beam 40.

[0040] Optionally, such as Figure 4 As shown, the dimension L2 of the vertical section 42 in the front-back direction (second direction) is greater than the dimension L1 of the vertical section 12 in the front-back direction (second direction). By reducing the dimension of the vertical section 12 in the front-back direction, the width of the entire frame is minimized as much as possible. This allows the computerized embroidery machine to be loaded into the container without disassembling the backpack structure of the frame during container transport. Increasing the dimension of the vertical section 42 in the front-back direction improves the stability of the computerized embroidery machine's operation and further ensures the quality of the embroidery.

[0041] It should be noted that L2 can be, but is not limited to, greater than L1, but this embodiment does not elaborate on this point.

[0042] Optionally, such as Figure 4 As shown, the dimension L3 of the transverse portion 41 in the front-to-back direction (second direction) is smaller than the dimension L4 of the transverse segment 11 in the front-to-back direction (second direction).

[0043] In practical applications, when the computerized embroidery machine is running, the vibration and impact generated by the main beam are absorbed by the transverse section 11 of the main body 10, and the mechanical energy generated by the vibration is transmitted to the ground through the vertical section 12 in the form of mechanical energy transmission, thereby playing a role in vibration filtering. Since the transverse part 41 of the beam is connected to the transverse section 11 as a whole, the transverse part 41 of the beam can absorb the vibration and impact at the transverse end, and then transmit it to the ground through the vertical part 42 of the beam.

[0044] Without affecting the vibration filtering effect of the stiffener, the transverse portion 41 of the beam should be minimized as much as possible, i.e., L3 should be less than L4, so as to reduce the material cost of the entire first stiffening beam 40.

[0045] It should be noted that L3 can be, but is not limited to, less than L4, and this embodiment does not elaborate on this point.

[0046] In another specific embodiment, the reinforcing member includes a reinforcing plate 20, which includes a horizontal portion 21 and a vertical portion 22. The reinforcing plate 20 is disposed on both sides of the body 10 in the first direction and is threadedly connected to the body 10.

[0047] like Figure 1 and Figure 2 As shown, the reinforcing plate 20 can be disposed on the left and right sides of the body 10. The reinforcing plate 20 can be, but is not limited to, made of carbon steel.

[0048] The reinforcing plate 20 includes a horizontal portion 21 and a vertical portion 22. The horizontal portion 21 extends in the front-to-back direction, and the vertical portion 22 extends in the up-down direction. One end of the horizontal portion 21 and one end of the vertical portion 22 can be welded together, or the two ends can be integrally formed.

[0049] The reinforcing component also includes a second reinforcing beam 30, which is straight. The second reinforcing beam 30 is a profile, and can be, but is not limited to, square steel, flat steel, or channel steel. The second reinforcing beam 30 can be made of, but is not limited to, carbon steel.

[0050] like Figure 2 As shown, two reinforcing plates 20 are disposed on both sides of the body 10 in the left-right direction, and the reinforcing plates 20 are threadedly connected to the body 10. A second reinforcing beam 30 is disposed between the two reinforcing plates 20, and the second reinforcing beam 30 is threadedly connected to the reinforcing plates 20. In detail:

[0051] The horizontal portion 21 of the plate is provided with a first through hole 211 that matches the first threaded hole, and the vertical portion 22 of the plate is provided with a second through hole 221 that matches the second threaded hole. Bolts pass through the first through hole 211 and connect to the first threaded hole, and bolts pass through the second through hole 221 and connect to the second threaded hole, thereby realizing the threaded connection between the reinforcing plate 20 and the body 10.

[0052] The second reinforcing beam 30 is a square steel beam sandwiched between the reinforcing plates 20 on the left and right sides. The sum of the dimensions of the second reinforcing plate 20 and the vertical section 12 in the front-back direction (second direction) is equal to the dimension of the vertical part 22 of the plate in the front-back direction (second direction), so that the second reinforcing beam 30 fits snugly against the vertical section 12.

[0053] like Figure 2As shown, multiple fourth positioning plates 15 are also provided on the surface of the vertical section 12 facing the second reinforcing beam 30, and each fourth positioning plate 15 has a fourth threaded hole. The multiple fourth positioning plates 15 are arranged at equal intervals from top to bottom on the surface of the vertical section 12 facing the second reinforcing beam 30. The surface of the second reinforcing beam 30 facing away from the vertical section 12 has a third clearance hole 32, and the surface facing the vertical section 12 has a third connecting hole. The third clearance hole 32 and the third connecting hole are coaxially arranged, and the third clearance hole 32 is larger than the third connecting hole. Bolts pass through the third clearance hole 32 and are connected at the junction of the third connecting hole and the fourth threaded hole. The fourth positioning plates 15 allow for accurate positioning and connection of the second reinforcing beam 30 and the vertical section 12.

[0054] A third positioning plate 31 is provided on the surface where the second reinforcing beam 30 connects to the reinforcing plate 20. The third positioning plate 31 has a third threaded hole. Bolts pass through the second through hole 221 of the left reinforcing plate 20 and are connected to the third threaded hole on the left side of the second reinforcing beam 30; bolts pass through the second through hole 221 of the right reinforcing plate 20 and are connected to the third threaded hole on the right side of the second reinforcing beam 30. With the setting of the first positioning plate 13, the second positioning plate 14 and the third positioning plate 31, the second reinforcing beam 30 and the reinforcing plate 20, and the vertical section 12 and the reinforcing plate 20 can be accurately positioned and connected.

[0055] In this way, when transporting the computer embroidery machine in a container, the second reinforcing beam 30 and the reinforcing plate 20 can be removed from the main body 10 without disassembling the backpack structure of the frame, so as to avoid the width of the entire frame being too wide, so that the frame can be loaded into the container at the current moment; after the container arrives at its destination, the main body 10 is reinforced by the rear side of the second reinforcing beam 30 and the left and right sides of the main body 10 by the two reinforcing plates 20, so as to improve the stability of the computer embroidery machine and further ensure the quality of the embroidery.

[0056] Optionally, the dimension of the transverse portion 21 of the plate in the front-back direction (second direction) is smaller than the dimension of the transverse segment 11 in the front-back direction (second direction). Without affecting the vibration filtering effect of the reinforcing member, the dimension of the transverse portion 21 of the plate is minimized as much as possible to reduce the overall material cost of the reinforcing plate.

[0057] In another specific embodiment, the reinforcing member is disposed on the lower frame side of the transverse section 11 facing away from the frame and on the lower frame side of the vertical section 12 facing away from the frame.

[0058] like Figure 5 As shown, the horizontal section 11 is located on the side opposite to the lower frame, that is, on the upper side of the horizontal section 11, and the vertical section 12 is located on the side opposite to the lower frame, that is, on the rear side of the vertical section 12. The reinforcing member can be a third reinforcing beam 50, which has a structure largely the same as the second reinforcing beam 40. The third reinforcing beam 50 is constructed according to... Figure 5 It is installed on the main body 10 as shown.

[0059] This application also provides a frame for a computerized embroidery machine, including the aforementioned backpack structure. This frame of the computerized embroidery machine possesses the advantages of a backpack structure. With an increased frame length and higher upper shaft speed, the strength and rigidity of the entire backpack structure can be increased by incorporating reinforcing members, thereby improving the stability of the backpack structure and further enhancing the stability of the computerized embroidery machine. Simultaneously, the reinforcing members are detachably connected to the main body 10, allowing the frame to be loaded into a container after the reinforcing members are removed, facilitating the loading, unloading, and transportation of the computerized embroidery machine.
