Description

Technical Field

[0001] The invention relates to the technical field of chain oiling, and in particular to an oiling machine and method for a drying kiln chain. Background Art

[0002] There are 12 vertical chains in the drying kiln, and all 12 chains need to be regularly refueled and maintained. The refueling machine delivers lubricating oil to the chain through hydraulic and electric means. The basic principle is to spray or drip lubricating oil to the chain joints with appropriate pressure and flow through the hydraulic pump and solenoid valve to reduce the wear and friction of the chain and extend the service life. At present, the chain refueling machine has the following main problems: First, the refueling machine is equipped with a refueling pipeline on each chain, and there are 12 refueling pipelines in total, which are used to refuel the 12 chains respectively. There are problems such as complex and cumbersome pipeline installation, large space occupation, and large workload for later maintenance; second, the oil outlet drips oil directly to the chain, making it difficult to accurately refuel the pin shaft sleeve of the chain, resulting in low refueling efficiency and waste of lubricating oil. Summary of the invention

[0003] The invention provides a refueling machine method for a drying kiln chain, which is used to solve the problems of how to reduce the installation and maintenance work of pipelines, reduce the floor space, improve the refueling efficiency and reduce the waste of lubricating oil.

[0004] In one aspect, the present invention provides a refueling machine for a drying kiln chain, comprising:

[0005] tank;

[0006] An oil delivery pipe, one end of which is connected to the oil tank;

[0007] An injection mechanism, connected to the other end of the oil delivery pipe, for spraying oil to the chain;

[0008] A horizontal moving mechanism, connected to the ejection mechanism, and used to drive the ejection mechanism to move horizontally;

[0009] The lifting mechanism is connected to the horizontal moving mechanism and is used to drive the horizontal moving mechanism to move in a vertical direction, thereby driving the spraying mechanism to move vertically.

[0010] In some embodiments, the spraying mechanism includes:

[0011] A first injection assembly is located on one side of the upper portion of the chain;

[0012] a second injection assembly, located on the other side of the upper portion of the chain;

[0013] A third injection assembly, located on one side of the lower portion of the chain;

[0014] a fourth injection assembly, located on the other side of the lower portion of the chain;

[0015] The mounting member is used to fix the first injection assembly, the second injection assembly, the third injection assembly and the fourth injection assembly on the oil delivery pipe.

[0016] In some embodiments, the first jetting assembly includes:

[0017] The jet main pipe has an arc-shaped structure;

[0018] The fuel injection nozzle is installed on the injection main pipe.

[0019] In some embodiments, the first injection assembly further comprises:

[0020] The jet port is installed on the jet main pipe.

[0021] In some embodiments, the fuel injection nozzle is spaced apart from the air injection port.

[0022] In some embodiments, the air jet is located below the fuel injection nozzle, and both the fuel injection nozzle and the air jet are strip-shaped structures.

[0023] In some embodiments, the lifting mechanism includes:

[0024] First Drive;

[0025] A transmission device connects the first driver and the injection mechanism.

[0026] In some embodiments, the actuator comprises:

[0027] a first ball screw, the screw shaft being connected to the first driver;

[0028] A first slide plate connected to a nut of the first ball screw;

[0029] The first guide rail is vertically arranged, and the first slide plate can move up and down along the first guide rail.

[0030] In some embodiments, the horizontal movement mechanism comprises:

[0031] First dovetail plate;

[0032] A second dovetail groove plate, interlocked with the first dovetail groove plate;

[0033] The second driver is capable of driving the first dovetail plate to move in a direction approaching or away from the chain.

[0034] On the other hand, the present invention also provides a method for refueling a drying kiln chain, using a refueling machine for a drying kiln chain, the method comprising:

[0035] The lifting mechanism drives the injection mechanism to move to the chain height, the horizontal moving mechanism drives the injection mechanism to move to the chain position, the oil tank delivers lubricating oil to the injection mechanism through the oil pipe, and the injection mechanism injects the lubricating oil to the chain.

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. Compared with the prior art, the refueling machine is equipped with one refueling pipeline on each chain, with a total of 12 refueling pipelines, which are used to refuel the 12 chains respectively. There are problems such as complicated and cumbersome pipeline installation, large space occupied, and large amount of subsequent maintenance work. The refueling machine for the drying kiln chain provided in the present application only needs to be equipped with one oil pipeline and one spraying mechanism. The spraying mechanism is raised or lowered to the horizontal height of different chains through the lifting mechanism, and then the spraying mechanism is moved in the direction of approaching or moving away from the chain through the horizontal moving mechanism until the spraying mechanism is aligned with the chain to spray oil, which greatly reduces the number of oil pipelines, thereby reducing the installation and subsequent maintenance work of the oil pipelines and reducing the space occupied by the oil pipelines;

[0038] 2. By setting the air jet port, the air is sprayed into the gap between the pin and the sleeve of the chain. The airflow pushes the lubricating oil from both ends to the middle between the pin and the sleeve. The lubricating oil is more likely to infiltrate the middle of the gap between the pin and the sleeve and the entire contact surface. Along the axial direction of the pin, from both ends to the middle, it is convenient for the lubricating oil to diffuse and infiltrate in the gap between the pin and the sleeve, thereby improving the refueling efficiency and accuracy.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] As described in the background technology, the use of traditional chain oilers has the problems of complicated and cumbersome pipeline installation, large space occupation, large amount of later maintenance work, and difficulty in accurately oiling the pin shaft sleeve of the chain, low oiling efficiency, waste of lubricating oil, etc. Therefore, how to reduce the installation and maintenance work of the pipeline, reduce the space occupation, and improve the oiling efficiency and reduce the waste of lubricating oil has become a technical problem that needs to be solved urgently by those skilled in the art.

[0047] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides a refueling machine for a drying kiln chain, comprising: an oil tank 1, an oil pipeline 2, a spraying mechanism 3, a horizontal moving mechanism 5 and a lifting mechanism 6. One end of the oil pipeline 2 is connected to the oil tank 1, and the other end is connected to the spraying mechanism 3. The oil tank 1 provides lubricating oil to the spraying mechanism 3 through the oil pipeline 2. The spraying mechanism 3 sprays oil to the chain 4 to perform oiling and maintenance on the chain 4. The horizontal moving mechanism 5 is connected to the spraying mechanism 3 to drive the spraying mechanism 3 to move horizontally; the lifting mechanism 6 is connected to the horizontal moving mechanism 5 to drive the horizontal moving mechanism 5 to move in the vertical direction, thereby driving the spraying mechanism 3 to move vertically.

[0048] Compared with the prior art, the refueling machine is provided with one refueling pipeline on each chain, and there are 12 refueling pipelines in total, and the 12 chains are refueled respectively, which has the problems of complicated and cumbersome pipeline installation, large space occupation, and large workload of later maintenance. The refueling machine for the drying kiln chain provided by the present application only needs to be provided with one oil pipeline 2 and one injection mechanism 3, and the injection mechanism 3 is raised or lowered to the horizontal height of different chains 4 through the lifting mechanism 6, and then the injection mechanism 3 is moved in the direction of approaching or moving away from the chain 4 through the horizontal moving mechanism 5, until the injection mechanism 3 is aligned with the chain 4 for oil injection, which greatly reduces the number of oil pipelines, thereby reducing the installation and later maintenance workload of the oil pipelines, and reducing the space occupied by the oil pipelines.

[0049] In some embodiments, the spray mechanism 3 includes: a mounting member 7 and a first spray assembly 31, a second spray assembly 32, a third spray assembly and a fourth spray assembly fixedly mounted on the mounting member 7. The first spray assembly 31 is located on one side of the upper part of the chain 4 and sprays oil on one side of the upper part of the chain 4; the second spray assembly 32 is located on the other side of the upper part of the chain 4 and sprays oil on the other side of the upper part of the chain 4; the third spray assembly is located on one side of the lower part of the chain 4 and sprays oil on one side of the lower part of the chain 4; the fourth spray assembly is located on the other side of the lower part of the chain 4 and sprays oil on the other side of the lower part of the chain 4. By setting up four spray assemblies to spray oil on both sides of the upper and lower parts of the chain 4 respectively, the lubricating oil enters between the pin shaft and the sleeve of the chain 4 from four directions, which facilitates the lubricating oil to enter between the pin shaft and the sleeve from both ends to the middle, and facilitates the lubricating oil to enter the middle of the outer periphery of the pin shaft, so that the oiling is more accurate and efficient.

[0050] In some embodiments, the first injection assembly 31, the second injection assembly 32, the third injection assembly and the fourth injection assembly have the same structure. The mounting member 7 is a U-shaped structure, which is fixedly connected to the first injection assembly 31, the second injection assembly 32, the third injection assembly and the fourth injection assembly. A position sensor is installed on the mounting member 7 to facilitate the detection of the position of the chain 4, and then adjust the injection mechanism 3 to the position of the chain 4. There are multiple position sensors, which are respectively used to detect the pin and sleeve positions of the chain 4, so as to achieve accurate matching of the injection mechanism 3 and the refueling position of the chain 4, and achieve accurate refueling.

[0051] In some embodiments, the first injection assembly 31 includes: an injection mother pipe 311 and an oil injection nozzle 312 installed on the injection mother pipe 311, and the injection mother pipe 311 is arranged in an arc structure. The injection mother pipe 311 with an arc structure has the same curvature as the sleeve of the chain 4, and has better adaptability, so that the oil injection nozzle 312 on the injection mother pipe 311 can accurately align with the gap between the pin shaft and the sleeve of the chain 4, and the oil injection is more accurate.

[0052] In some embodiments, the first injection assembly 31 further includes: an injection port 313, which is installed on the injection mother pipe 311. In specific implementation, air can be supplied by retracting the piston, or by connecting an air compressor, both of which are prior arts. By setting the injection port 313, the air is sprayed into the gap between the pin shaft and the sleeve of the chain 4, and the lubricating oil is pushed from both ends to the middle direction into the gap between the pin shaft and the sleeve by the airflow, so that the lubricating oil is more likely to infiltrate the middle part and the entire contact surface of the gap between the pin shaft and the sleeve, and in the axial direction of the pin shaft, along the two ends to the middle direction, it is convenient for the lubricating oil to diffuse and infiltrate in the gap between the pin shaft and the sleeve.

[0053] In some embodiments, such as Figure 5 As shown, the oil nozzle 312 is spaced apart from the air jet 313. The oil nozzle 312 and the air jet 313 are arranged along the curvature of the injection mother pipe 311. The oil nozzle 312 and the air jet 313 have the same injection direction and angle, and both are sprayed toward the gap between the pin shaft and the end of the sleeve. The oil nozzle 312 sprays lubricating oil into the gap between the pin shaft and the end of the sleeve, and the air jet 313 sprays air into the gap between the pin shaft and the end of the sleeve. The gas pushes the lubricating oil to flow and infiltrate from the end to the middle along the axial direction of the pin shaft, and the lubricating oil can quickly reach the middle of the outer periphery of the pin shaft, thereby improving the refueling efficiency and accuracy.

[0054] In some embodiments, such as Figure 3 As shown, the jet port 313 is located below the oil nozzle 312, and both the oil nozzle 312 and the jet port 313 are strip-shaped structures. The strip-shaped structure is consistent with the curvature of the injection mother pipe 311, and the injection direction and angle of the oil nozzle 312 and the jet port 313 can accurately adapt to the curvature of the pin and the sleeve, and accurately spray lubricating oil and gas into the gap between the pin and the sleeve.

[0055] In some embodiments, such as Figure 4 As shown, the jet port 313 is located below the fuel injector 312, the jet port 313 is connected to the air pipe, the fuel injector 312 is connected to the oil pipe, the oil pipe is connected to the oil pipeline 2, and the extension lines of the air pipe and the oil pipe converge forward at an acute angle, thereby ensuring that the lubricating oil and gas sprayed by the fuel injector 312 and the jet port 313 can converge in the gap between the pin shaft and the sleeve, thereby achieving precise refueling.

[0056] In some embodiments, the lifting mechanism 6 includes: a first driver 61 and a transmission, and the transmission connects the first driver 61 and the spraying mechanism 3. The first driver 61 drives the spraying mechanism 3 to rise or fall through the transmission, and then lifts the spraying mechanism 3 to the level of different chains 4, so that the spraying mechanism 3 adds lubricating oil to different chains 4. Preferably, the first driver 61 is a servo motor.

[0057] In some embodiments, the transmission device includes: a first ball screw 62, a first slide 63 and a first guide rail, the screw shaft of the first ball screw 62 is connected to the first driver 61, the first slide 63 is connected to the nut of the first ball screw 62, the first guide rail is vertically arranged, and the first slide 63 can move up and down along the first guide rail. By providing a servo motor and the first ball screw 62, the precise lifting and lowering of the injection mechanism 3 is achieved, so that the injection mechanism 3 can be precisely adjusted to the same horizontal height as the chain 4.

[0058] In some embodiments, the horizontal movement mechanism 5 includes: a second driver and a first dovetail groove plate 51 and a second dovetail groove plate 52 that are interlocked with each other, and the second driver can drive the first dovetail groove plate 51 to move in a direction close to or away from the chain 4. Preferably, the second driver can be a servo motor, the first dovetail groove plate 51 is fixedly connected to the first mounting plate, the second dovetail groove plate 52 is fixedly connected to the second mounting plate, the second driver is connected to the second ball screw, the nut end of the second ball screw is welded to the first mounting plate, the second ball screw is slidably connected to the second mounting plate, and the second dovetail groove plate 52 is welded to the first slide plate 63. The second driver drives the first dovetail groove plate 51 to move in a direction close to or away from the chain 4 through the second ball screw, thereby driving the injection mechanism 3 to move in a direction close to or away from the chain 4. By setting the servo motor and the second ball screw, the injection mechanism 3 can be accurately adjusted in a direction close to or away from the chain 4, and by setting two dovetail groove plates that are interlocked with each other, the injection mechanism 3 can be adjusted horizontally.
