Description

Technical Field

[0001] This application relates to the field of sewing machine technology, and in particular to a side-mounted sewing machine. Background Technology

[0002] A sewing machine is a machine that uses mechanical, electronic, or computer-controlled mechanisms to systematically thread stitches through fabric or other flexible materials, thereby sewing them together. Its invention revolutionized the textile and garment manufacturing industry and is a significant achievement in human industrial history.

[0003] Most sewing machines are placed upright on the machine table. However, for intelligent manufacturing purposes, some production lines use sewing machines mounted horizontally on the machine table. When mounted horizontally, the fabric moves vertically on the sewing machine, with the original bottom of the machine facing the horizontal side. The original side wall serves as the mounting wall on the machine table. An oil tank is located on top of the machine table. The original oil supply system at the bottom of the sewing machine pumps oil from the tank into the machine for lubrication when mounted upright. However, with the side-mounted configuration, the oil supply lines cannot supply oil, affecting the machine's operation. Summary of the Invention

[0004] In order to ensure that the sewing machine can be properly lubricated when it is placed on its side and to enable the sewing machine to be used normally, this application provides a side-mounted sewing machine.

[0005] This application provides a side-mounted sewing machine, which adopts the following technical solution:

[0006] A side-mounted sewing machine includes a sewing machine body mounted on its side. A mounting plate is provided on the mounting surface of the sewing machine body and the machine table. The mounting plate is used for mounting to the machine table. An oil pump is provided on the side of the mounting plate away from the sewing machine body. An oil inlet pipe is provided on the oil pump. Lubricating oil in the oil tank enters the oil pump through the oil inlet pipe. Several oil distribution pipes are provided at the oil outlet end of the oil pump. The oil distribution pipes extend into the sewing machine body and are aligned with several points that need lubrication.

[0007] By adopting the above technical solution, when the sewing machine needs to be installed on the machine table in a side-lying position, it is connected and fixed to the machine table through a mounting plate. An oil pump is set on the side of the mounting plate away from the sewing machine body. The oil distribution pipe on the oil pump outlet extends into the sewing machine body and is aligned with several points that need lubrication. When the sewing machine is installed in a side-lying position, a new oil supply system is set up to pump the oil in the oil tank into the sewing machine for lubrication. This avoids the oil supply line being unable to supply oil due to the different placement direction after the machine is placed on its side. The sewing machine can be normally lubricated when placed on its side, and the sewing machine can be used normally.

[0008] Optionally, the mounting plate protrudes from both ends of the sewing machine body, and the mounting plate has several mounting holes at the protrusions of the sewing machine body, through which bolts pass to connect with the machine base.

[0009] By adopting the above technical solution, the two ends of the mounting plate protrude from the sewing machine body, which facilitates the opening of mounting holes and connection and fixation with the machine base, making installation and disassembly convenient.

[0010] Optionally, the sewing machine body is provided with a first lubrication chamber, a second lubrication chamber and a third lubrication chamber, and the ends of the plurality of oil distribution pipes away from the oil pump are respectively located in the first lubrication chamber, the second lubrication chamber and the third lubrication chamber.

[0011] By adopting the above technical solution, lubrication is provided to the components in the first lubrication chamber, the second lubrication chamber and the third lubrication chamber through the oil distribution pipe, so as to prevent jamming.

[0012] Optionally, it also includes several return pipes. The bottom of the mounting plate has several return holes for the return pipes to pass through. Each of the return pipes corresponds to one of the return holes. The return pipes are connected to the first lubrication chamber, the second lubrication chamber and the third lubrication chamber respectively. The end of the return pipe away from the first lubrication chamber is used to connect to the oil tank. The lubricating oil in the first lubrication chamber, the second lubrication chamber and the third lubrication chamber flows back to the oil tank through the return pipes.

[0013] By adopting the above technical solution, the reflux hole facilitates the passage of the reflux pipe, and the excess lubricating oil in the first lubrication chamber, the second lubrication chamber and the third lubrication chamber is allowed to flow back to the oil tank through the reflux pipe by gravity, which facilitates the recycling of lubricating oil.

[0014] Optionally, the oil distribution pipe is a flexible hose.

[0015] By adopting the above technical solution, the hose has a certain deformation performance, and it is easy to penetrate into the body of the sewing machine through the hose.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. When the sewing machine is installed on its side, a new oil supply system is set up to pump the oil in the oil tank into the sewing machine for lubrication. This avoids the oil supply line being unable to supply oil due to the different placement direction after the machine is placed on its side. The sewing machine can be lubricated normally when placed on its side, and can be used normally.

[0018] 2. The mounting plate facilitates connection and fixation to the machine base, and is also easy to disassemble;

[0019] 3. Excess lubricating oil in the first lubrication chamber, the second lubrication chamber, and the third lubrication chamber flows back to the oil tank by gravity through the return pipe, which facilitates the recycling of lubricating oil. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a side-mounted sewing machine. (Refer to...) Figure 1 The side-mounted sewing machine includes a sewing machine body 1 that is mounted on its side. A mounting plate 2 is fixed to the mounting surface of the sewing machine body 1 and the machine base. The mounting plate 2 is used for mounting to the machine base. The two ends of the mounting plate 2 protrude from the sewing machine body 1, and several mounting holes 6 are opened at the protrusions of the mounting plate 2 from the sewing machine body 1. The mounting holes 6 are for bolts to pass through and connect to the machine base.

[0027] An oil pump 3 is fixed to the side of the mounting plate 2 away from the sewing machine body 1. An oil inlet pipe 4 is connected to the oil pump 3. Lubricating oil from the oil tank enters the oil pump 3 through the oil inlet pipe 4. An oil distributor 91 is fixed to the oil outlet of the oil pump 3. The oil distributor 91 has several oil distribution ports 92, each connected to an oil distribution pipe 5. The oil distribution pipes 5 extend into the sewing machine body 1 and are aligned with several areas requiring lubrication. Both the oil inlet pipe 4 and the oil distribution pipes 5 are flexible hoses.

[0028] The sewing machine body 1 has a first lubrication chamber 71, a second lubrication chamber 72, and a third lubrication chamber 73. Several oil distribution pipes 5, with their ends furthest from the oil pump 3, are located in the first lubrication chamber 71, the second lubrication chamber 72, and the third lubrication chamber 73, respectively. The side-mounted sewing machine also includes three return pipes 82. The bottom of the mounting plate 2 has three return holes 81 through which the return pipes 82 pass. Each return pipe 82 corresponds to one of the return holes 81, and the return pipes 82 are flexible hoses. The return pipes 82 are connected to the first lubrication chamber 71, the second lubrication chamber 72, and the third lubrication chamber 73, respectively. The end of the return pipe 82 furthest from the first lubrication chamber 71 is connected to the oil tank. The lubricating oil in the first lubrication chamber 71, the second lubrication chamber 72, and the third lubrication chamber 73 flows back to the oil tank through the return pipes 82.

[0029] The implementation principle of a side-mounted sewing machine according to an embodiment of this application is as follows: When the sewing machine needs to be installed on the machine table for use in a side-mounted position, it is connected and fixed to the machine table through the mounting plate 2. The oil pump 3 is fixed on the side of the mounting plate 2 away from the sewing machine body 1 to facilitate oil supply when the sewing machine is installed in a side-mounted position. The oil distribution pipe 5 on the oil outlet end of the oil pump 3 extends into the sewing machine body 1 and supplies oil to the first lubrication chamber 71, the second lubrication chamber 72 and the third lubrication chamber 73 for lubrication. Excess lubricating oil in the first lubrication chamber 71, the second lubrication chamber 72 and the third lubrication chamber flows back to the oil tank through the return pipe 82. When the sewing machine is installed in a side-mounted position, the oil pump 3 in the oil tank is introduced into the sewing machine for lubrication by setting up a new oil supply system, so as to avoid the oil supply line being unable to supply oil due to the different placement direction after side-mounting. The sewing machine can be normally lubricated when side-mounted, and the sewing machine can be used normally.
