Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to an embroidery machine head housing. Background Technology

[0002] To improve efficiency, existing embroidery machines typically have multiple sewing heads mounted side-by-side on the main beam, sewing simultaneously. The housing of the sewing head is fixed to the main beam, and the back plate of the housing is connected and positioned to the main beam through mounting holes and positioning holes. In existing technology, there are generally two mounting holes, located at the upper end of the back plate; there are also two positioning holes, one at the upper end of the back plate and one in the middle of the back plate. Since the housing usually needs to install many drive cams, connecting shafts, and other structures, if screws are inserted into the positioning holes in the middle of the back plate, the rotation angle of the drive cams inside the housing needs to be adjusted to provide sufficient space for operation and installation, which increases the difficulty of installation and positioning.

[0003] Additionally, one side panel of the casing is usually machined as a single piece with the casing, while the other side has an opening to facilitate the installation of internal parts. Furthermore, the top and bottom ends of the side with the opening lack connecting structures, resulting in relatively low rigidity of the casing. After the internal parts are installed, a removable cover is used to completely cover the opening and seal the casing. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a machine head housing for an embroidery machine. The housing and main beam are easy to install and position, the overall rigidity of the housing is high, and the movable plate located at the side opening has high strength.

[0005] The technical solution adopted is as follows: An embroidery machine head housing includes a housing, a back plate disposed on the housing for connection with a main beam, a side plate disposed on one side of the housing and integrally formed with the housing, and an opening on the other side of the housing. The back plate extends to both sides with extension plates, each extension plate having a first mounting hole. The side of the housing with the opening includes a movable plate covering the opening of the housing and an mounting block integrally formed with the housing and extending upward. The movable plate is disposed at the upper end of the mounting block. The housing also has a column at the opening connecting the upper and lower profiles of the housing.

[0006] Furthermore, the first mounting holes are symmetrically arranged.

[0007] Furthermore, two second mounting holes are provided at the upper end of the back plate.

[0008] Furthermore, a positioning hole is provided between the two second mounting holes.

[0009] Furthermore, the movable plate includes two mutually cooperating first movable plates and second movable plates.

[0010] Furthermore, the first and second movable plates are provided with mutually cooperating arc grooves to form shaft holes for the connecting shaft to pass through.

[0011] Furthermore, the lower end of the housing is provided with an inclined surface that connects to the back plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a housing for an embroidery machine head. Two extension plates extending to both sides are provided on the back plate of the housing, and first mounting holes are provided on the extension plates for fixing the housing to a main beam. Adding two first mounting holes and placing them on the outside of the housing facilitates installation and disassembly, resulting in a tighter connection and better fixation. An integral mounting block extending upwards from the bottom of the housing is provided on one side of the opening. A movable plate is provided at the upper end of the mounting block. The mounting block not only increases the area and strength of the housing but also reduces the size of the opening, shortening the length of the movable plate. With the thickness remaining constant, the shorter length increases the strength of the movable plate. In addition, a column connecting the upper and lower profiles of the housing is provided at the opening, further increasing the strength of the housing. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments.

[0015] refer to Figure 1-6An embroidery machine head housing includes a housing 1, a back plate 2 disposed on the housing 1 for connection with a main beam, a side plate 8 disposed on one side of the housing 1 and integrally formed with the housing, and an opening 9 on the other side of the housing 1. The back plate 2 extends to both sides and is provided with extension plates 4. Each extension plate 4 is provided with a first mounting hole 5. The side of the housing 1 with the opening includes a movable plate 6 covering the opening of the housing 1 and an mounting block 13 integrally formed with the housing 1 and extending upward. The movable plate 6 is disposed at the upper end of the mounting block 13. The housing 1 is also provided with a column 7 at the opening for connecting the upper and lower profiles of the housing.

[0016] The mounting block 13 is integrally formed with the housing 1. The movable plate 6 is detachably mounted on the edge of the housing and the mounting block 13 to seal and protect the interior of the housing 1, while leaving an opening 9 to facilitate the installation, disassembly, or maintenance of internal structures such as cams. The integral connection between the mounting block 13 and the housing 1 reduces the size of the opening 9 while still ensuring the installation of internal parts. A smaller opening 9 results in a shorter length of the movable plate 6 covering it. For the same thickness, a shorter length results in higher strength for the movable plate 6.

[0017] Preferably, the first mounting holes 5 are symmetrically arranged. Symmetrical arrangement of the first mounting holes 5 provides better positioning and facilitates observation of whether the installation position is accurate. Fixing the two first mounting holes 5 on both sides provides a more secure fixation. Furthermore, the two first mounting holes 5 being located on the outer side facilitates the installation of connecting bolts.

[0018] Two second mounting holes 3 are also provided at the upper end of the back plate 2 for connecting the back plate 1 and the main beam. The use of four mounting holes (top and bottom) ensures a good connection and fixation. A positioning hole 10 is provided between the two second mounting holes 3. A pin can be inserted into the positioning hole to position the housing 1 on the main beam, and then the connecting bolts can be placed into the first and second mounting holes for installation. Alternatively, a positioning hole can also be provided in the middle of the back plate 1.

[0019] The opening of the casing 1 is also equipped with a column 7 that connects the upper and lower profiles of the casing, which further increases the overall rigidity of the casing 1 and makes it more load-bearing.

[0020] The movable plate 6 includes two mutually cooperating first movable plates 601 and second movable plates 602. The first and second movable plates are provided with mutually cooperating arc grooves, forming shaft holes 11 for the connecting shaft to pass through.
