An integrated lubrication device for industrial sewing machines

Abstract

This utility model discloses an integrated lubrication device for industrial sewing machines, belonging to the field of sewing machine maintenance technology. It includes a sewing machine body, with a mounting platform fixedly installed on one side of the top of the sewing machine body. A motor is located on one side of the mounting platform, and the motor's output end is rotatably connected to the mounting platform via a bearing. This integrated lubrication device for industrial sewing machines, by setting up a motor and a pusher plate, allows the oil injection cylinder to be fixed on the top of the mounting platform. A connecting block is engaged in the connecting slot. Starting the motor causes the rotating gear to rotate, causing the connecting rack to drive the limiting slide strip to slide within the limiting slide groove. This, in turn, causes the pusher plate to continuously push the push rod into the oil injection cylinder, causing the piston plate to squeeze and deliver lubricating oil from inside the oil injection cylinder, which drips continuously from the cylinder's output port. The oil then passes through the piston plate into the oil injection port on the top of the sewing machine body, continuously lubricating the needle bar and preventing jamming or excessive wear.

[0002] Industrial sewing machines are specialized machines used for the mass production of textile products such as clothing and home textiles. Compared to household sewing machines, they have the core characteristics of high-speed operation, high stability, and specialized functions, and can meet the needs of continuous high-intensity operation. Therefore, it is necessary to continuously drip lubricating oil into the oil injection port of the industrial sewing machine to ensure the stability of the industrial sewing machine during continuous high-intensity operation. When lubricating existing industrial sewing machines, it is usually necessary to stop the sewing machine from working and manually inject a certain amount of lubricating oil into the oil injection port before continuing to use the sewing machine. This leads to a decrease in the working efficiency of industrial sewing machines, and it is difficult for humans to judge when the sewing machine needs to be lubricated, making the sewing machine more susceptible to damage. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an integrated lubrication device for industrial sewing machines. It solves the problem that when lubricating existing industrial sewing machines, it is usually necessary to stop the sewing machine and manually inject a certain amount of lubricating oil into the oil inlet before continuing to use the sewing machine. This results in a decrease in the working efficiency of industrial sewing machines, and it is difficult to judge the required oil injection time manually, making the sewing machine susceptible to damage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated lubrication device for industrial sewing machines, comprising a sewing machine body, an mounting platform fixedly installed on one side of the top of the sewing machine body, a motor provided on one side of the mounting platform, the output end of the motor being rotatably connected to the mounting platform via a bearing, rotating gears fixedly installed on the surfaces of the motor output end on both sides of the mounting platform, limiting grooves penetrating the top of both sides of the mounting platform, a push plate slidably connected to one side of the mounting platform, limiting strips fixedly installed on both sides of the push plate inside the limiting groove, and the limiting strips sliding inside the limiting groove, a connecting rack fixedly connected to the side of the limiting strip away from the push plate, and the connecting rack meshing with the rotating gears, two insertion slots provided on the top of the push plate, an oil injection cylinder provided on the top of the mounting platform, a push rod slidably connected to one end of the oil injection cylinder, two insertion blocks fixedly installed on one end of the push rod, a snap-fit ​​plate fixedly installed on one side of the two insertion blocks, and the insertion blocks slidably inserted into the insertion slots.

[0005] As a further embodiment of this utility model: the top of the mounting platform is provided with two positioning grooves, and the bottom of the oil injection cylinder is fixedly installed with two positioning blocks, and the positions of the positioning blocks correspond to the positioning grooves.

[0006] As a further embodiment of this utility model: connecting blocks are fixedly installed on both sides of the oil injection cylinder, and the top of the connecting blocks is provided with a slot.

[0007] As a further embodiment of this utility model: the top two sides of the mounting platform are rotatably connected to a locking plate by a pin, and the locking plate is fastened inside the locking groove.

[0008] As a further embodiment of this utility model: a piston plate is fixedly installed at one end of the push rod located inside the oil injection cylinder, and a return spring is sleeved on the surface of the push rod located outside the oil injection cylinder.

[0009] As a further embodiment of this utility model: a flow guide frame is fixedly installed at one end of the top of the sewing machine body, and the top of the flow guide frame corresponds to the position of the oil injection cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This integrated lubrication device for industrial sewing machines, by setting up a motor and a pusher plate, when the oil injection cylinder is fixed on the top of the mounting platform, the plug block is engaged inside the plug slot. Starting the motor causes the rotating gear to rotate, which causes the connecting rack to drive the limiting slide strip to slide inside the limiting slide groove. This causes the pusher plate to push the push rod to move continuously into the oil injection cylinder, so that the piston plate squeezes and delivers the lubricating oil inside the oil injection cylinder, which drips continuously from the output port of the oil injection cylinder. After passing through the piston plate, it enters the oil injection port on the top of the sewing machine body, completing the continuous lubrication of the needle bar of the sewing machine body and preventing the needle bar from jamming or excessive wear.

[0011] 2. This industrial sewing machine uses an integrated lubrication device. By setting a clamping plate and a clamping groove, after the lubricating oil inside the oil injection cylinder is exhausted, the clamping plate is pushed open from the groove, the oil injection cylinder is removed from the top of the mounting platform, and the output end of the oil injection cylinder is immersed in the lubricating oil. At the same time, the return spring returns and causes the piston plate to move inside the oil injection cylinder, drawing lubricating oil into the oil injection cylinder. Then, the positioning block is aligned with the positioning groove, and the insertion block is inserted into the insertion groove. Finally, the clamping plate is rotated to snap into the groove, completing the replenishment and replacement of the lubricating oil inside the oil injection cylinder. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-3 As shown, this utility model provides a technical solution: an integrated lubrication device for industrial sewing machines, including a sewing machine body 1, a mounting platform 2 fixedly installed on one side of the top of the sewing machine body 1, a motor 3 provided on one side of the mounting platform 2, the output end of the motor 3 being rotatably connected to the mounting platform 2 via a bearing, rotating gears 4 being fixedly installed on the surfaces of the motor 3 on both sides of the mounting platform 2, a limiting slide groove 5 penetrating through the top of both sides of the mounting platform 2, a push plate 6 being slidably connected through one side of the mounting platform 2, and limiting slide strips 7 being fixedly installed on both sides of the push plate 6 inside the limiting slide groove 5, and the limiting slide strips 7 sliding inside the limiting slide groove 5. By providing the limiting slide groove 5, the limiting slide strips 7 move within the limiting slide groove 5, thereby preventing the push plate 6 from shifting during movement and making it difficult for the push plate 6 to detach from the mounting platform 2.

[0015] A connecting rack 8 is fixedly connected to the side of the limiting slide bar 7 away from the push plate 6, and the connecting rack 8 meshes with the rotating gear 4. The top of the push plate 6 is provided with two insertion slots 9, and the top of the mounting platform 2 is provided with an oil injection cylinder 10. One end of the oil injection cylinder 10 is slidably connected to a push rod 11. Two insertion blocks 12 are fixedly installed on one end of the push rod 11. A snap-fit ​​plate 13 is fixedly installed on one side of the two insertion blocks 12, and the insertion blocks 12 are slidably inserted into the insertion slots 9. By providing the insertion blocks 12, the insertion blocks 12 are inserted into the insertion slots 9. The push plate 6 is located between the snap-fit ​​plate 13 and the push rod 11, so that the push rod 11 moves synchronously with the push plate 6 to drive the piston plate 20 to slide inside the oil injection cylinder 10.

[0016] The top of the mounting platform 2 is provided with two positioning grooves 17, and the bottom of the oil injection cylinder 10 is fixedly installed with two positioning blocks 16, and the positioning blocks 16 correspond to the positions of the positioning grooves 17. By providing positioning grooves 17, the positioning blocks 16 at the bottom of the oil injection cylinder 10 are inserted into the positioning grooves 17, so that the oil injection cylinder 10 will not be offset when placed on the top of the mounting platform 2.

[0017] Connecting blocks 14 are fixedly installed on both sides of the oil injection cylinder 10. The top of the connecting blocks 14 is provided with a slot 15. The top sides of the mounting platform 2 are rotatably connected to the locking plates 18 by pins, and the locking plates 18 are fastened inside the slots 15. With the locking plates 18, after the oil injection cylinder 10 is placed on the top of the mounting platform 2, the locking plates 18 are rotated and fastened into the slots 15 on the top of the connecting blocks 14, thereby fixing the oil injection cylinder 10 on the top of the mounting platform 2.

[0018] A piston plate 20 is fixedly installed at one end of the push rod 11 inside the oil filling cylinder 10. A return spring 19 is sleeved on the outer surface of the push rod 11 outside the oil filling cylinder 10. With the return spring 19, when the oil filling cylinder 10 with used lubricating oil is placed into the lubricating oil tank, the return spring 19 rebounds and pushes out the push rod 11, causing the piston plate 20 to move inside the oil filling cylinder 10 to replenish the lubricating oil in the oil filling cylinder 10.

[0019] A flow guide frame 21 is fixedly installed at one end of the top of the sewing machine body 1, and the top of the flow guide frame 21 corresponds to the position of the oil injection cylinder 10. With the flow guide frame 21, the lubricating oil dripping from the output end of the oil injection cylinder 10 flows into the oil injection hole of the sewing machine body 1 along the flow guide frame 21, so that the flow direction of the lubricating oil will not be deviated.

[0020] The working principle of this utility model is as follows: The positioning block 16 at the bottom of the oil injection cylinder 10 is engaged with the positioning groove 17 at the top of the mounting platform 2. At the same time, the insertion block 12 is inserted into the insertion groove 9, and the rotating clamping plate 18 is engaged in the groove 15, thereby fixing the oil injection cylinder 10 on the top of the mounting platform 2. The motor 3 is started to make the rotating gears 4 on both sides of the mounting platform 2 rotate, driving the connecting rack 8 to move, so that the limiting slide 7 slides in the limiting slide groove 5, thereby causing the push plate 6 to drive the push rod 11 to move into the oil injection cylinder 10. The piston plate 20 moves and squeezes the lubricating oil inside the oil injection cylinder 10, causing the lubricating fluid to flow out continuously from the inside of the oil injection cylinder 10. The lubricating oil flows through the guide frame 21 into the oil injection hole at the top of the sewing machine body 1, thereby continuously lubricating the needle bar of the sewing machine body 1. When the lubricating oil inside the oil injection cylinder 10 is exhausted, rotate the clamp plate 18 away from the top of the connecting block 14, remove the oil injection cylinder 10, and place the output end of the oil injection cylinder 10 into the lubricating oil tank. The push rod 11 returns to its original position, causing the oil injection cylinder 10 to move and draw lubricating oil into the oil injection cylinder 10 until the push rod 11 returns to its original position. At the same time, start the motor 3 to reverse and reset the push plate 6. Then, install the oil injection cylinder 10 on the top of the mounting platform 2 to complete the lubricating oil replenishment of the oil injection cylinder 10.
