Description

Technical Field

[0001] This utility model relates to the field of bearing seat lubrication technology for coating machine ovens, specifically to a coating machine oven with a self-lubricating bearing seat system. Background Technology

[0002] The bearing housings of the lithium battery coating machine oven are key components installed at both ends of the guide rollers inside the coating machine oven. They support the rotation of the guide rollers and ensure the stable transport of the substrate (such as lithium electrode foil) inside the oven. These bearing housings are directly exposed to the high-temperature environment of the oven, and due to the compact internal space of the oven, multiple bearing housings are densely arranged with narrow installation gaps and extremely limited surrounding space.

[0003] Currently, the lubrication of these bearing housings faces numerous challenges: Firstly, existing self-lubricating devices are bulky, and their oil reservoirs, pipelines, and other structures cannot be adapted to the compact installation environment of the bearing housings, making effective deployment difficult. Secondly, the capacity of the oil reservoir components in existing devices is too small, requiring frequent replacement. However, the oven area has a large number of bearing housings (each bearing housing often requires 1-2 oil reservoir components), resulting in high purchase costs and time-consuming, labor-intensive manual oil changes, leading to low maintenance efficiency. Furthermore, due to the limitations of the devices, actual operation still relies heavily on manual, periodic application of grease using an oil gun. Because of the large number of bearing housings and the hot, stuffy working environment, this process is not only time-consuming but also poses a risk of heatstroke for personnel. Moreover, manual application makes it difficult to ensure even oil distribution, affecting lubrication effectiveness.

[0004] Therefore, how to develop a coating machine oven with a bearing housing and self-lubricating system that is suitable for compact spaces, has a simplified structure, and reduces reliance on manual maintenance is an urgent problem that needs to be solved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a coating machine oven with a bearing housing self-lubricating system, including a frame, a housing, bearing housings, and a bearing housing self-lubricating system composed of a power lubrication unit and a distribution and delivery unit. Through the distributor and the temperature-resistant and corrosion-resistant oil pipes, an independent lubrication path is formed for each bearing housing, realizing automated and precise lubrication, adapting to the compact layout of the coating machine oven and reducing manual maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] frame;

[0009] Multiple housings are provided, each housing is mounted on the frame, and multiple mounting holes are formed at certain intervals on two opposite side walls of each housing along its length.

[0010] Multiple bearing seats are fixed to the outer wall of the housing and are arranged corresponding to the mounting holes. The top of each bearing seat has an oil injection port. A guide roller for conveying the substrate is arranged between two opposing bearing seats.

[0011] The bearing housing self-lubricating system includes:

[0012] The power lubrication unit is located in the middle of the frame and includes an oil reservoir and a pump body arranged in series. The lower part of the oil reservoir has multiple output ports and an operation panel located below the output ports for controlling the start and stop of the pump body.

[0013] The oil distribution unit includes a distributor located at the bottom of the housing. The distributor has an oil inlet and multiple oil outlets. The oil inlet is connected to the output port via a high-pressure oil pipe, and the oil outlets are connected to the oil filling port of each bearing housing via temperature-resistant and corrosion-resistant oil pipes, so as to achieve independent lubrication of each bearing housing.

[0014] According to one example, the distributor is a progressive distributor, which includes a housing and a plurality of plunger chambers arranged in series within the housing, wherein a plunger is slidably disposed in each plunger chamber; the oil inlet is disposed at one end of the housing and is connected to the oil inlet end of the first plunger chamber near the oil inlet; the oil outlet end of each plunger chamber is connected to a corresponding oil outlet; and adjacent plunger chambers are connected through an internal oil passage.

[0015] According to one example, the bearing housing includes a housing body, a mounted spherical bearing is disposed in the middle of the housing body, the oil inlet corresponds to the upper part of the mounted spherical bearing, and the inner end of the oil inlet extends into the bearing raceway region.

[0016] According to one example, the oil inlet is provided with an externally threaded nozzle, and the end of the temperature-resistant and corrosion-resistant oil pipe is provided with an internally threaded connector, the nozzle being threadedly connected to the connector.

[0017] According to one example, the output port is equipped with a three-way pipe, the first end of which is equipped with an oil pressure gauge, the second end of which forms a high-pressure oil outlet and is connected to the high-pressure oil pipe, and the third end of which forms an oil overflow outlet.

[0018] According to one example, both ends of the high-pressure oil pipe are provided with quick-connect fittings, which are respectively connected to the oil inlet and the high-pressure oil outlet.

[0019] According to one example, the side wall of the housing is provided with a cable tray, the opening of the cable tray is provided with a cover plate, and the high-pressure oil pipe and the temperature-resistant and corrosion-resistant oil pipe pass through the cable tray.

[0020] According to one example, the frame includes a first support frame and a second support frame vertically disposed on the ground, and a central column disposed between the first support frame and the second support frame, the housing is located between the first support frame and the second support frame, and the power lubrication unit is disposed on the central column.

[0021] According to one example, the top of the box is detachably provided with a box cover, and a lifting assembly is provided between the box and the box cover. The lifting assembly is used to drive the box cover to move along the height direction of the box to open or close the box.

[0022] According to one example, the lifting assembly includes:

[0023] A cylinder mounting bracket is vertically fixed to the outer wall of the housing;

[0024] A cylinder, which is fixed to the cylinder mounting base, and the free end of the cylinder is hinged to the outer wall of the box cover;

[0025] A guide sleeve, which is vertically fixed to the outer wall of the housing;

[0027] The guide rod is arranged parallel to the cylinder.

[0028] This utility model has the following advantages:

[0029] This utility model discloses a coating machine oven with a self-lubricating bearing housing system. The power lubrication unit is integrated into the central column of the frame, and the distributor is positioned close to the lower part of the oven body. Oil pipes are arranged in an orderly manner through wiring channels, and the overall structure is adapted to the compact space of the oven. The power lubrication unit includes an oil reservoir and a pump body. The pump body is connected to high-pressure oil pipes through multiple output ports, providing stable grease delivery power to the entire system. The oil distribution unit adopts a progressive distributor. The plunger chambers connected in series within the housing and the sliding plunger form an orderly mechanical distribution structure. When grease enters from the inlet, the plungers sequentially push the grease out through the outlet, ensuring that each outlet delivers a corresponding quantitative amount of grease to the bearing housing, achieving precise control of sequential oil discharge and circulating oil supply. Temperature-resistant and corrosion-resistant oil pipes connect the distributor to the oil inlets of the bearing housings, forming independent lubrication pathways for each bearing housing.

[0030] The self-lubricating bearing housing system replaces traditional manual lubrication, reducing operator workload and safety risks associated with working in confined spaces. Furthermore, precise mechanical control prevents uneven oil distribution and grease overflow during manual lubrication, thus preventing grease contamination of the foil and ensuring product quality. Simultaneously, the transparent overflow pipe and oil pressure gauge facilitate real-time monitoring of the oil circuit, automatically draining oil when blockages occur, ensuring stable system operation, reducing maintenance costs and failure rates, and providing reliable protection for the coating machine oven.

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figure 1This paper illustrates an embodiment of a coating machine oven with a self-lubricating bearing housing system. The oven mainly includes a frame 1, a housing 2, bearing housings 3, and a self-lubricating bearing housing system composed of a power lubrication unit 4 and a distribution oil delivery unit 5. The frame 1 serves as an integral support structure, on which multiple housings 2 are mounted along their length. Multiple bearing housings 3 are mounted on the outer walls of the housings 2 along their length. The frame 1, housings 2, and bearing housings 3 constitute the basic load-bearing frame of the coating machine oven. To address the problems of cumbersome operation, uneven lubrication, and difficulty in adapting to the compact space of the oven due to manual lubrication of the bearing housings 3 in existing technologies, this embodiment integrates a self-lubricating bearing housing system composed of a power lubrication unit 4 and a distribution oil delivery unit 5 onto the basic frame. The power lubrication unit 4 provides stable oil pressure, and the distribution oil delivery unit 5 achieves precise oil distribution, ultimately realizing automated, independent, and precise lubrication of multiple bearing housings 3. This not only adapts to the compact layout of the coating machine oven but also reduces manual maintenance costs and operational errors.

[0039] The frame 1 serves as the supporting structure for the coating machine oven. It includes a first support frame 101 and a second support frame 102 vertically mounted on the ground. The first support frame 101 is located at the front of the coating machine oven, and the second support frame 102 is located at the rear of the coating machine oven. A central column 103 is positioned between the first support frame 101 and the second support frame 102. The housing 2 is located between the first support frame 101 and the central column 103, or between the central column 103 and the second support frame 102. The central column 103 is parallel to both the first support frame 101 and the second support frame 102. Crossbeams 104 are provided between the first support frame 101 and the central column 103, and between the second support frame 102 and the central column 103, for fixed support.

[0040] Multiple boxes 2 are arranged on the frame 1. There are four boxes 2, which are respectively defined as the first box, the second box, the third box and the fourth box. The first box and the second box are arranged vertically between the first support frame 101 and the central column 103, while the third box and the fourth box are arranged vertically between the central column 103 and the second support frame 102, so that the boxes 2 are a certain distance away from the ground. On the two opposite side walls of each box 2, a plurality of mounting holes 201 are formed at certain intervals along its length. The number of mounting holes 201 in the first box is 10, the number of mounting holes 201 in the second box is 13, the number of mounting holes 201 in the third box is 8, and the number of mounting holes 201 in the fourth box is 10. It should be noted that the number of boxes 2 and the number of mounting holes 201 are not fixed and can be flexibly adjusted according to the width and length of the substrate to be dried and the production efficiency. For example, the number of boxes 2 can be 2, 3 or 6, etc., and the number of mounting holes 201 in a single box 2 can be 6, 8 or 12, etc., as long as the mounting holes 201 on the opposite side walls correspond one-to-one.

[0041] Reference Figure 1 and Figure 4 Multiple bearing seats 3 are symmetrically distributed along the length of the housing 2, corresponding to the mounting holes 201. Each housing 2 has bearing seats 3 fixed on two opposite outer walls, and the positions of the bearing seats 3 on both sides correspond one-to-one with the mounting holes 201, forming several sets of oppositely arranged bearing assemblies. A guide roller for conveying the substrate is provided between each set of opposite bearing seats 3. The axis of the guide roller extends along the transverse direction of the housing 2 and is located in the inner cavity of the housing 2. Its two ends are connected to the bearing structures of the bearing seats 3 on both sides, so as to achieve rotation to convey the substrate.

[0042] The bearing housing 3 includes a horizontally arranged seat body 302. A vertical plate 304 extends vertically upward from the side of the seat body 302 closest to the side wall of the housing 2. The vertical plate 304 engages with the mounting hole 201 of the housing 2 and is snapped together. The snapping structure can be achieved by providing a limiting protrusion on the edge of the vertical plate 304, and forming a groove on the inner wall of the mounting hole 201 that engages with the limiting protrusion, ensuring a stable connection between the bearing housing 3 and the housing 2. A seated spherical bearing 303 is provided in the middle of the seat body 302. The inner ring of the bearing engages with the end of the guide roller, and its outer ring is fixed to the seat body 302, ensuring smooth rotation of the guide roller.

[0043] The bearing housing 3 is provided with an oil inlet 301 on the top. The outer end of the oil inlet 301 is provided with an external threaded oil nozzle 301a for connecting to an external oil supply line. Its inner end extends to the raceway area of ​​the bearing, so that the injected lubricating oil can directly act on the friction surface, thereby shortening the lubrication path and ensuring lubrication efficiency.

[0044] Continue to refer to Figure 1The bearing housing self-lubrication system includes a power lubrication unit 4 and a distribution oil delivery unit 5. The power lubrication unit 4 serves as the power source for the self-lubrication system. It is located in the middle of the frame 1, specifically in the center of the central column 103, within the gap between the two vertically arranged housings 2, saving space and facilitating pipeline layout. The bearing housing self-lubrication system uses one power lubrication unit 4 with four distribution oil delivery units 5. Each distribution oil delivery unit 5 corresponds to a bearing housing assembly in one housing 2 for lubrication, allowing for more than 40 bearing housings 3 to be used.

[0045] The power lubrication unit 4 includes an oil reservoir 401 and a pump body 402 arranged in series. The oil reservoir 401 is made of transparent material and has an internal volume of 4L, allowing for direct observation of the internal lubricating oil level for timely replenishment. Multiple output ports 402a are provided at its lower part. In this embodiment, four housings 2 are correspondingly provided with four output ports 402a. Each output port 402a is individually connected to the distribution and delivery unit 5 of one housing 2 via a pipeline. The oil outlet of the pump body 402 is connected to the multiple output ports 402a at the lower part of the oil reservoir 401 through an internal oil passage. When the pump body 402 is working, it pressurizes the lubricating oil in the oil reservoir 401 and delivers it to each output port 402a through the internal oil passage. Since the four housings 2 are equipped with four output ports 402a respectively, and the internal oil passages of the pump body 402 adopt a diversion structure, the pressurized lubricating oil can be distributed to the four output ports 402a simultaneously or in a set order, and then transported to the distribution oil delivery section 5 through the high-pressure oil pipes 502 connected to the output ports 402a. This arrangement ensures that a single pump body 402 can simultaneously provide lubrication power to the bearing seats 3 of multiple housings 2.

[0046] An operation panel 403 is provided at the lower part of the oil storage chamber 401 and below the output port 402a. The operation panel 403 is provided with multiple buttons. One button is used to trigger the start or stop action of the pump body 402. The other buttons correspond to different mechanical gears. For example, by switching gears, parameters such as the action interval, single running time and number of cycles of the pump body 402 can be adjusted.

[0047] Reference Figure 1 and Figure 2 Each output port 402a of the oil storage chamber 401 is equipped with a corresponding three-way pipe 402b. The three-way pipe 402b is sealed to the output port 402a through a threaded joint, forming a transfer structure that integrates pressure monitoring, oil circuit transportation and safety overflow.

[0048] The first end of the three-way pipe 402b is located at its upper part and is equipped with an oil pressure gauge 402c. The oil pressure gauge 402c displays the lubricating oil pressure in the pipeline. The operator can visually judge whether the oil circuit is in normal working condition through the dial reading. The range of the oil pressure gauge 402c is 0-30MPa, and the accuracy is ±0.5%. The second end of the three-way pipe 402b is located in its middle part and extends horizontally to form a high-pressure oil outlet. The high-pressure oil outlet is connected to one end of the high-pressure oil pipe 502 through a quick-connect fitting, serving as the main channel for conveying lubricating oil and guiding the pressurized lubricating oil to the distribution oil delivery section 5. The third end of the three-way pipe 402b is located at its lower part and forms an oil overflow port 402d. An overflow valve is installed at the oil overflow port 402d. When the pipeline is blocked and the pressure exceeds the threshold, the overflow valve automatically opens, allowing excess lubricating oil to be discharged from the port to prevent pipeline rupture. To facilitate visual monitoring of the overflow status, a transparent plastic tube is also connected to the oil overflow port 402d. The outlet end of the transparent tube can be connected to a recovery container. By observing whether there is oil flow inside the transparent tube, operators can quickly determine whether the oil circuit is blocked, thus improving the convenience of maintenance.

[0049] Reference Figure 1 and Figure 3 The oil distribution and delivery unit 5 includes a distributor 501 located at the lower part of the housing 2, which achieves precise distribution and delivery of lubricating oil through pipeline connections. The distributor 501 is provided with an oil inlet 501b and multiple oil outlets 501c. The oil inlet 501b is connected to the high-pressure oil outlet of the power lubrication unit 4 through a high-pressure oil pipe 502. Both ends of the high-pressure oil pipe 502 are equipped with quick-connect fittings, which are respectively connected to the threaded interfaces of the oil inlet 501b and the high-pressure oil outlets. The oil outlets 501c are connected to the oil filling ports 301 of each bearing housing 3 through temperature-resistant and corrosion-resistant oil pipes 503, forming independent lubrication branches.

[0050] The temperature and corrosion resistant oil pipe 503 is made of pressure-resistant semi-transparent Teflon material, which is suitable for the temperature environment inside the oven and facilitates observation of the oil flow in the pipe. The end near the oil inlet 301 is provided with an internal threaded connector, which is threaded to the external threaded oil nozzle 301a at the oil inlet 301. An O-ring is provided at the connection between the oil nozzle 301a and the connector to further improve the sealing performance and prevent lubricating oil leakage.

[0051] Continue to refer to Figure 3The distributor 501 adopts a CV-8 type single-cycle progressive distributor, which includes a housing 501a and multiple plunger chambers (not shown in the figure) arranged sequentially in series along the length of the housing 501a. Each plunger chamber is equipped with a plunger that can slide along the cavity axis. Two adjacent plunger chambers are connected by an internal oil passage. The oil inlet 501b is located at one end of the housing 501a and is connected to the oil inlet end of the first plunger chamber near the end of the housing 501a. The oil outlet end of each plunger chamber is connected to an oil outlet 501c. The number of oil outlets 501c can be configured from 6 to 20 depending on the number of bearing seats 3. For example, if the first housing corresponds to 10 bearing seats 3, its distributor 501 is equipped with 10 oil outlets 501c to ensure that each bearing seat 3 can be connected to the corresponding oil outlet 501c through an independent oil pipe. When high-pressure lubricating oil flows into the first plunger chamber from the inlet 501b, the oil pressure pushes the plunger inside the chamber to slide along the length of the chamber, forcing the pre-stored lubricating oil in the chamber to be discharged through the outlet 501c. At the same time, the high-pressure oil is introduced into the next plunger chamber through the internal oil passage. Subsequent plunger chambers operate in the same manner until all outlets 501c have completed one oil discharge cycle, thus completing one oil filling cycle. This progressive action ensures that each outlet 501c can output a fixed amount of lubricating oil in sequence, and the next cycle will continue from the position where the previous cycle ended. The precise distribution of lubricating oil is achieved through the orderly linkage of the mechanical structure.

[0052] In an embodiment not shown, a cable tray is provided along the length of the side wall of the housing 2. The cable tray has a groove-type structure with a U-shaped cross-section. A cover plate is detachably provided at the opening of the cable tray. The cover plate is fastened to the opening to form a closed space to prevent the oil pipe from being damaged by external impact. Both the high-pressure oil pipe 502 and the temperature-resistant and corrosion-resistant oil pipe 503 pass through the cable tray, and different types of oil pipes can be distinguished and fixed by the partition plate provided in the cable tray.

[0053] Reference Figure 1 The top of the box 2 is detachably provided with a box cover 202. A lifting component 203 is provided between the box 2 and the box cover 202. The opening and closing action is realized by the lifting component 203. The lifting component 203 is arranged along the height direction of the box 2 and drives the box cover 202 to move in the vertical direction, thereby opening or closing the box 2.

[0054] Reference Figure 5The lifting assembly 203 mainly includes a cylinder mounting base 203a, a cylinder 203b, a guide sleeve 203c, and a guide rod 203d. The cylinder mounting base 203a is a plate-shaped structure, which is fixed to the outer wall of the housing 2 by bolts. The cylinder body of the cylinder 203b is fixed to the upper surface of the cylinder mounting base 203a by a flange. The free end of its piston rod extends upward and is hinged to the outer wall of the housing cover 202 by a hinge structure, ensuring that the piston rod can drive the housing cover 202 to rise and fall when it extends and retracts. The guide sleeve 203c is a tubular structure, fixed to the outer wall of the housing 2 and arranged side by side with the cylinder mounting base 203a. The lower end of the guide rod 203d passes through the guide sleeve 203c and can slide along the axial direction of the guide sleeve 203c. Its upper end is fixed to the outer wall of the housing cover 202 by welding or bolts, forming a two-point support for the housing cover 202 with the piston rod of the cylinder 203b. Cylinder 203b acts as a power element, providing the driving force for the lifting and lowering of the lid 202. The cooperation between guide rod 203d and guide sleeve 203c serves as a limiting function, preventing the lid 202 from shifting or wobbling during lifting and lowering, and ensuring that the lid 202 can accurately align with the opening of the box body 2. At the same time, the parallel arrangement of cylinder 203b and guide rod 203d ensures that the lid 202 is subjected to balanced force.
