Description

Technical Field

[0001] The utility model relates to the field of sewing machine lubrication, in particular to an interactive lubrication system for sewing machines. Background Art

[0002] At present, there is a type of lubrication system for sewing machines as follows, the lubrication system includes a left oil pump group and a right oil pump group and a left oil zone and a right oil zone. The left oil zone and the right oil zone each have an oil storage chamber, and the oil storage chambers of the left oil zone and the right oil zone are not connected. The left oil pump group includes a left oil pump and an oil suction pipe and an oil supply pipe connected to the left oil pump, and the right oil pump group includes a right oil pump and an oil suction pipe and an oil supply pipe connected to the right oil pump. The left oil pump group is responsible for supplying and returning oil to the left oil zone, and the right oil pump group is responsible for supplying and returning oil to the right oil zone. The left and right oil supply and return systems are independent of each other. At the same time, in order to avoid oil leakage from the oil pump to the outside, resulting in oil loss, the left oil pump and the right oil pump are arranged in the same oil storage chamber. At present, the lubrication system of this type of sewing machine has the following shortcomings,

[0003] Due to the manufacturing precision of the oil pump parts and the long-term wear of the oil pump, there is always a slight leakage when the oil pump is supplying oil, and the oil leaked from the oil pump can only leak into the oil storage cavity of one of the oil zones, resulting in an imbalance of the oil volume in the oil storage cavities of the left and right oil zones after long-term use. The following description takes the left and right oil pumps arranged in the oil storage cavities of the left oil zone as an example. The oil leaked from the oil pump can only leak into the oil storage cavities of one of the left oil zones. After long-term use, the amount of oil in the oil storage cavity of the right oil zone gradually decreases, resulting in insufficient lubrication on the right side, increased heat and wear, and even jamming when there is no oil; and too much oil on the left side will also increase the risk of oil leakage. In addition, since the left and right sets of oil supply and return systems are independent of each other, the user needs to refuel in the oil storage cavities of the left and right oil zones each time (that is, refuel twice), which is inconvenient to operate. Utility Model Content

[0004] The purpose of the utility model is to provide an interactive lubrication system for sewing machines in which the oil in two oil storage chambers that are not connected to each other can circulate with each other to balance the oil amounts in the two oil storage chambers; thereby effectively solving the problem in the prior art that the oil amounts in the oil storage chambers in the two oil zones are unbalanced, resulting in insufficient lubrication on one side and increased heating and wear.

[0005] The technical solution of the utility model is:

[0006] An interactive lubrication system for a sewing machine, comprising:

[0007] A first oil storage chamber and a second oil storage chamber that are not connected to each other;

[0008] Two oil pumps, the two oil pumps are located in the first oil storage chamber, the inlet of each oil pump is connected to the oil suction pipe, and the outlet of each oil pump is connected to the oil supply pipe;

[0009] The oil suction pipe of one of the oil pumps is connected to the first oil storage chamber, and the oil sprayed out of the oil supply pipe of the oil pump flows back into the second oil storage chamber;

[0010] The oil suction pipe of another oil pump is connected to the second oil storage chamber, and the oil sprayed from the oil supply pipe of the oil pump flows back to the first oil storage chamber. The specific working process of the interactive lubrication system for sewing machines of this scheme is as follows: during the working process of the two oil pumps, the oil suction pipe of one oil pump draws the oil in the first oil storage chamber, and the oil pump sprays to the lubricating parts of the sewing machine through the oil supply pipe for oil spraying lubrication, and the oil sprayed from the oil supply pipe of the oil pump flows back to the second oil storage chamber; the oil suction pipe of the other oil pump draws the oil in the second oil storage chamber, and the oil pump sprays to the lubricating parts of the sewing machine through the oil supply pipe for oil spraying lubrication, and the oil sprayed from the oil supply pipe of the oil pump flows back to the first oil storage chamber; in this way, the oil in the two oil storage chambers that are not connected to each other can circulate with each other, and even if the oil pump leaks oil, the amount of oil in the two oil storage chambers can be balanced. Therefore, it can effectively solve the problem in the prior art that the two oil areas are independent of each other (the left oil pump group is responsible for supplying and returning oil to the left oil area, and the right oil pump group is responsible for supplying and returning oil to the right oil area), and the problem of uneven oil volume in the oil storage chambers of the two oil areas due to oil pump leakage, resulting in insufficient lubrication on one side, increased heat and wear, and even jamming when there is no oil; and the problem of excessive oil volume on the other side also leads to an increased risk of oil leakage.

[0011] On the other hand, since the oil in the two unconnected oil storage chambers can circulate with each other during the operation of the two oil pumps, the user only needs to refuel the first oil storage chamber when refueling. After the two oil pumps are working, the two unconnected oil storage chambers can quickly reach oil balance, which is convenient for the user's refueling operation.

[0012] Preferably, the two oil pumps share a driving shaft, so that the same power element can be used to drive the two oil pumps to rotate synchronously through the same driving shaft, and the two oil pumps can rotate at the same speed to ensure that the oil suction and injection amounts of the two oil pumps are consistent.

[0013] Preferably, the driving shaft is connected to the main shaft of the sewing machine through a gear transmission mechanism or a pulley transmission mechanism. In this solution, the main shaft of the sewing machine is used as a power element to drive the driving shaft to rotate, and then the same driving shaft drives the two oil pumps to rotate synchronously. In this way, it is possible to save the need for additional power elements to drive the oil pumps, which is beneficial to reducing costs and improving the compactness of the sewing machine layout structure.

[0014] Preferably, the two oil pumps are connected as one. The two oil pumps are connected as one, so that the two oil pumps can be installed in place synchronously at one time during installation, which is convenient for the installation of the oil pumps.

[0015] Preferably, an oil storage container is connected to the oil suction pipe. During the operation of the oil pump, a certain amount of oil will be stored in the oil storage container. Thus, after the oil pump stops working, a certain amount of oil will remain stored in the oil storage container, so that the oil suction pipe between the oil pump and the oil storage container and the inner cavity of the oil pump can maintain a certain amount of oil, which is conducive to the smooth suction of the oil in the oil storage cavity during the initial operation of the oil pump; thereby avoiding the oil in the oil suction pipe from being emptied after the oil pump stops working, which is not conducive to the suction of the oil in the oil storage cavity during the initial operation of the oil pump.

[0016] Preferably, the oil storage container is close to the corresponding oil pump. In this way, after the oil pump stops working, it is beneficial to keep a certain amount of oil in the oil suction pipe between the oil pump and the oil storage container and the inner cavity of the oil pump, which is beneficial for the oil pump to smoothly suck the oil in the oil storage cavity when it is initially working.

[0017] Preferably, the oil storage container is provided with two upper and lower interfaces, the lower interface is located at the lower part or bottom of the oil storage container, the oil suction pipe includes two sections of oil pipe, the rear section of the oil pipe connects the lower interface of the oil storage container and the corresponding oil pump inlet, and the front section of the oil pipe is connected to the upper interface of the oil storage container. Since the lower interface is located at the lower part or bottom of the oil storage container and the upper interface is located above the lower interface, after the oil pump stops working, it is beneficial for the oil storage container to keep storing a certain amount of oil, so that the oil suction pipe between the oil pump and the oil storage container and the inner cavity of the oil pump can keep a certain amount of oil, which is beneficial for the oil pump to smoothly suck the oil in the oil storage cavity when it is initially working.

[0018] Preferably, the oil storage container is located in the first oil storage cavity or the second oil storage cavity. This is beneficial for arranging the oil storage container without occupying other spaces of the sewing machine; on the other hand, when the oil storage container leaks, the oil will flow back to the first oil storage cavity or the second oil storage cavity to avoid oil loss.

[0019] Preferably, the oil storage container and the oil pump are located together in the first oil storage cavity, so that the oil storage container can be arranged conveniently.

[0020] Preferably, one end of the oil supply pipe is connected to the corresponding oil pump outlet, and the other end of the oil supply pipe is provided with a nozzle. Thus, during the operation of the oil pump, the oil supply pipe can spray oil through the nozzle to lubricate the lubricating parts of the sewing machine, which is beneficial to lubricate the lubricating parts of the sewing machine.

[0021] The beneficial effects of the utility model are:

[0022] First, the oil in the two unconnected oil storage chambers can circulate with each other, and even if the oil pump leaks oil, the oil volume in the two oil storage chambers can be balanced. Therefore, it can effectively solve the problem that the two oil areas in the prior art are independent of each other (the left oil pump group is responsible for supplying and returning oil to the left oil area, and the right oil pump group is responsible for supplying and returning oil to the right oil area), and the oil pump leaks, making the oil volume in the oil storage chambers of the two oil areas unbalanced, resulting in insufficient lubrication on one side, increased heat and wear, and even stuck when there is no oil; and the problem that too much oil on the other side also increases the risk of oil leakage.

[0023] Secondly, when refueling, the user only needs to fill the first oil storage chamber. After the two oil pumps are working, refueling in the two oil storage chambers that are not connected to each other can quickly achieve oil balance, which is convenient for the user's refueling operation.

[0035] Specific embodiment 1, as Figure 1 , Figure 2 As shown, an interactive lubrication system for a sewing machine includes a first oil storage chamber 1, a second oil storage chamber 2, and two oil pumps 3. The first oil storage chamber 1 and the second oil storage chamber 2 are not connected to each other. In this embodiment, the two oil pumps 3 are located in the first oil storage chamber 1. Of course, the two oil pumps 3 can also be arranged in the second oil storage chamber 2.

[0036] The inlet of each oil pump 3 is connected to the oil suction pipe 4 , and the outlet of each oil pump 3 is connected to the oil supply pipe 5 .

[0037] An oil suction pipe 4 of one of the oil pumps 3 is connected to the first oil storage chamber 1 , and the oil pump 3 sucks the oil in the first oil storage chamber 1 through the oil suction pipe 4 ; the oil sprayed out by the oil supply pipe 5 of the oil pump 3 flows back into the second oil storage chamber 2 .

[0038] The oil suction pipe 4 of another oil pump 3 is connected to the second oil storage chamber 2 , and the oil pump 3 sucks the oil in the second oil storage chamber 2 through the oil suction pipe 4 ; the oil sprayed out by the oil supply pipe 5 of the oil pump 3 flows back to the first oil storage chamber 1 .

[0039] The specific working process of the interactive lubrication system for sewing machines of this embodiment is as follows: during the working process of the two oil pumps 3, the oil suction pipe 4 of one of the oil pumps 3 draws the oil in the first oil storage chamber 1, and the oil pump 3 sprays the oil to the lubricating parts of the sewing machine through the oil supply pipe 5 for oil spraying lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the second oil storage chamber 2; the oil suction pipe 4 of the other oil pump 3 draws the oil in the second oil storage chamber 2, and the oil pump 3 sprays the oil to the lubricating parts of the sewing machine through the oil supply pipe 5 for oil spraying lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the first oil storage chamber 1; in this way, the oil in the two oil storage chambers that are not connected to each other can circulate with each other, and even if the oil pump 3 leaks oil (the leaked oil flows back to the first oil storage chamber 1), the oil amount in the first oil storage chamber 1 and the second oil storage chamber 2 can be balanced. Therefore, it can effectively solve the problem in the prior art that the two oil areas are independent of each other (the left oil pump 3 group is responsible for supplying and returning oil to the left oil area, and the right oil pump 3 group is responsible for supplying and returning oil to the right oil area), and the problem that the oil volume in the oil storage chambers of the two oil areas is unbalanced due to leakage of the oil pump 3, resulting in insufficient lubrication on one side, increased heat and wear, and even jamming when there is no oil; and the problem that too much oil on the other side also increases the risk of oil leakage.

[0040] On the other hand, since the oil in the two oil storage chambers (the first oil storage chamber 1 and the second oil storage chamber 2) that are not connected to each other can circulate mutually during the operation of the two oil pumps 3, the user only needs to add oil to the first oil storage chamber 1 when refueling. After the two oil pumps 3 are working, the two oil storage chambers that are not connected to each other can quickly reach oil balance, which is convenient for the user's refueling operation. Of course, the user can also only add oil to the second oil storage chamber 2 when refueling. After the two oil pumps 3 are working, the two oil storage chambers that are not connected to each other (the first oil storage chamber 1 and the second oil storage chamber 2) can quickly reach oil balance.

[0041] Specific embodiment 2, as Figure 1 , Figure 2As shown, an interactive lubrication system for a sewing machine includes a first oil area, a second oil area and two oil pumps 3, wherein the first oil area includes a first oil storage chamber 1 arranged in the casing of the sewing machine, and the second oil area includes a second oil storage chamber 2 arranged in the casing of the sewing machine. The first oil storage chamber 1 and the second oil storage chamber 2 are not connected to each other. In this embodiment, the two oil pumps 3 are located in the first oil storage chamber 1. Of course, the two oil pumps 3 can also be arranged in the second oil storage chamber 2 as needed. The oil pump 3 is fixedly mounted on the casing, for example, by bolts, rivets or clamping.

[0042] The inlet of each oil pump 3 is connected to the oil suction pipe 4 , and the outlet of each oil pump 3 is connected to the oil supply pipe 5 .

[0043] The oil suction pipe 4 of one of the oil pumps 3 is connected to the first oil storage chamber 1, and the oil pump 3 sucks the oil in the first oil storage chamber 1 through the oil suction pipe 4; the oil pump 3 sprays the lubricating parts of the sewing machine to the second oil zone through the oil supply pipe 5 for oil spray lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the second oil storage chamber 2.

[0044] The oil suction pipe 4 of another oil pump 3 is connected to the second oil storage chamber 2, and the oil pump 3 sucks the oil in the second oil storage chamber 2 through the oil suction pipe 4; the oil pump 3 sprays the lubricating parts of the sewing machine to the first oil zone through the oil supply pipe 5 for oil spray lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the first oil storage chamber 1.

[0045] The specific working process of the interactive lubrication system for sewing machines of this embodiment is as follows: during the working process of the two oil pumps 3, the oil suction pipe 4 of one of the oil pumps 3 draws the oil in the first oil storage chamber 1, and the oil pump 3 sprays the oil to the lubricating parts of the sewing machine through the oil supply pipe 5 for oil spraying lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the second oil storage chamber 2; the oil suction pipe 4 of the other oil pump 3 draws the oil in the second oil storage chamber 2, and the oil pump 3 sprays the oil to the lubricating parts of the sewing machine through the oil supply pipe 5 for oil spraying lubrication, and the oil sprayed from the oil supply pipe 5 of the oil pump 3 flows back to the first oil storage chamber 1; in this way, the oil in the two oil storage chambers that are not connected to each other can circulate with each other, and even if the oil pump 3 leaks oil (the leaked oil flows back to the first oil storage chamber 1), the oil amount in the first oil storage chamber 1 and the second oil storage chamber 2 can be balanced. Therefore, it can effectively solve the problem in the prior art that the two oil areas are independent of each other (the left oil pump 3 group is responsible for supplying and returning oil to the left oil area, and the right oil pump 3 group is responsible for supplying and returning oil to the right oil area), and the problem that the oil volume in the oil storage chambers of the two oil areas is unbalanced due to leakage of the oil pump 3, resulting in insufficient lubrication on one side, increased heat and wear, and even jamming when there is no oil; and the problem that too much oil on the other side also increases the risk of oil leakage.

[0046] On the other hand, since the oil in the two oil storage chambers (the first oil storage chamber 1 and the second oil storage chamber 2) that are not connected to each other can circulate mutually during the operation of the two oil pumps 3, the user only needs to add oil to the first oil storage chamber 1 when refueling. After the two oil pumps 3 are working, the two oil storage chambers that are not connected to each other can quickly reach oil balance, which is convenient for the user's refueling operation. Of course, the user can also only add oil to the second oil storage chamber 2 when refueling. After the two oil pumps 3 are working, the two oil storage chambers that are not connected to each other (the first oil storage chamber 1 and the second oil storage chamber 2) can quickly reach oil balance.

[0047] Furthermore, one end of the oil supply pipe 5 is connected to the corresponding outlet of the oil pump 3, and the other end of the oil supply pipe 5 is provided with a nozzle 5.1. There are one or more nozzles on the other end of the oil supply pipe 5. The same nozzle has one or more oil injection ports. In this way, during the operation of the oil pump 3, the oil supply pipe 5 can spray oil through the nozzle to lubricate the lubricating parts of the sewing machine, which is beneficial to lubricate the lubricating parts of the sewing machine.

[0048] In this embodiment, the oil suction pipe 4 and the oil supply pipe 5 both have a plurality of bent portions to avoid other components or structures in the sewing machine.

[0049] Furthermore, the two oil pumps 3 share a driving shaft. In this way, the same power element can be used to drive the two oil pumps 3 to rotate synchronously through the same driving shaft, while ensuring that the two oil pumps 3 have the same rotation speed, so that the oil suction and injection amounts of the two oil pumps 3 are consistent. Of course, it should be noted that the two oil pumps 3 can also be two independent oil pumps 3, and the two oil pumps 3 each use an independent driving shaft.

[0050] Furthermore, the two oil pumps 3 are connected as one. The two oil pumps 3 are connected as one, so that the two oil pumps 3 can be installed in place at one time during installation, which is convenient for the installation of the oil pumps 3. Of course, it should be noted that the two oil pumps 3 can also be two independent oil pumps 3, and the two oil pumps 3 are installed and fixed separately according to needs.

[0051] Furthermore, the driving shaft is connected to the main shaft 7 of the sewing machine through a gear transmission mechanism 8 or a pulley transmission mechanism. The main shaft 7 of the sewing machine (the main shaft 7 of the sewing machine is driven to rotate by a motor, and the main shaft 7 of the sewing machine is an existing structure of the sewing machine) is used as a power element to drive the driving shaft to rotate, and then the same driving shaft drives the two oil pumps 3 to rotate synchronously. In this way, it is possible to save the need for additional power elements to drive the oil pumps 3, which is conducive to reducing costs and improving the compactness of the layout structure of the sewing machine.

[0052] In one implementation of this embodiment, the drive shaft is parallel to the main shaft 7 of the sewing machine. The drive shaft and the main shaft 7 of the sewing machine are connected by a gear transmission mechanism 8. The main shaft 7 of the sewing machine is located below the drive shaft. The gear transmission mechanism is located in the first oil storage chamber 1. The two oil pumps 3 are arranged side by side, and the gear transmission mechanism is located between the two oil pumps 3. In this way, the gear transmission mechanism and the drive shaft can be lubricated by the oil in the first oil storage chamber 1. Of course, it should be noted that the main shaft 7 of the sewing machine can also be located above or on the left and right sides of the drive shaft.

[0053] In another implementation of this embodiment, the drive shaft is perpendicular to the main shaft 7 of the sewing machine. The drive shaft and the main shaft 7 of the sewing machine are connected by a gear transmission mechanism. The main shaft 7 of the sewing machine is located below the drive shaft. The drive shaft is horizontally distributed, and the main shaft 7 of the sewing machine is horizontally distributed. The gear transmission mechanism is located in the first oil storage chamber 1. In this way, the gear transmission mechanism and the drive shaft can be lubricated by the oil in the first oil storage chamber 1. Of course, it should be noted that the main shaft 7 of the sewing machine can also be located above the drive shaft.

[0054] Furthermore, the oil suction pipe 4 is connected to an oil storage container 6. In the present embodiment, the oil suction pipes 4 on the two oil pumps 3 are connected to the oil storage container 6. The shape of the oil storage container 6 may be circular, square or other special-shaped structures. During the operation of the oil pump 3, a certain amount of oil will be stored in the oil storage container 6. Thus, after the oil pump 3 stops working, a certain amount of oil will remain stored in the oil storage container 6, so that the oil suction pipe 4 between the oil pump 3 and the oil storage container 6 and the inner cavity of the oil pump 3 maintain a certain amount of oil, which is conducive to the smooth suction of the oil in the oil storage cavity when the oil pump 3 initially works; thereby avoiding the oil in the oil suction pipe 4 from being emptied after the oil pump 3 stops working, which is not conducive to the suction of the oil in the oil storage cavity when the oil pump 3 initially works.

[0055] The oil storage container 6 is close to the corresponding oil pump 3. In this way, after the oil pump 3 stops working, it is beneficial to keep a certain amount of oil in the oil suction pipe 4 between the oil pump 3 and the oil storage container 6 and the inner cavity of the oil pump 3, which is beneficial for the oil pump 3 to smoothly suck the oil in the oil storage cavity when it is initially working.

[0056] Specifically, the oil storage container 6 is provided with two upper and lower interfaces, and the position of the upper interface is higher than the position of the lower interface. In this embodiment, the lower interface is located at the lower part or bottom of the oil storage container 6, and the upper interface is located at the upper part of the oil storage container 6. The oil suction pipe 4 includes two sections of oil pipes, front and rear, wherein the rear section of the oil pipe 4.2 connects the lower interface of the oil storage container 6 with the corresponding inlet of the oil pump 3, one end of the front section of the oil pipe 4.1 is connected to the upper interface of the oil storage container 6, and the other end of the front section of the oil pipe is connected to the first oil storage chamber 1 or the second oil storage chamber 2. Since the lower interface is located at the lower part or bottom of the oil storage container 6, and the position of the upper interface is higher than the position of the lower interface, after the oil pump 3 stops working, it is beneficial for the oil storage container 6 to keep storing a certain amount of oil, so that the oil suction pipe 4 between the oil pump 3 and the oil storage container 6 and the inner cavity of the oil pump 3 can keep a certain amount of oil, which is beneficial for the oil pump 3 to smoothly suck the oil in the oil storage chamber when it is initially working.

[0057] Furthermore, the oil storage container 6 is located in the first oil storage chamber 1 or the second oil storage chamber 2. In the present embodiment, the oil storage container 6 is located in the first oil storage chamber 1 together with the oil pump 3. Of course, it should be noted that the oil storage container 6 may also be located in the second oil storage chamber 2, or the oil storage container 6 on the oil suction pipe 4 of one oil pump 3 is located in the first oil storage chamber 1, and the oil storage container 6 on the oil suction pipe 4 of the other oil pump 3 is located in the second oil storage chamber 2. In this way, on the one hand, it is conducive to the arrangement of the oil storage container 6, and other spaces of the sewing machine cannot be occupied additionally, which is conducive to improving the compactness of the structure; on the other hand, when the oil storage container 6 leaks oil, the oil will also flow back to the first oil storage chamber 1 or the second oil storage chamber 2 to avoid oil loss.

[0058] The above description is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent transformation made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
