Description

Technical Field

[0001] The utility model belongs to the technical field of bearing seats, and in particular relates to a high temperature resistant bearing seat mechanism for a discharge roller of a heating furnace. Background Art

[0002] During the production of the PBA line (thermoforming line), the roller of the heating furnace rotates to transport the parts (temperature>800℃) heated out of the furnace to the grabbing position of the upper loader. During the part transfer process, it will pass over the bearing seat in the middle of the roller. The bearing inside the bearing seat has been running in a high temperature environment for a long time. Over time, the internal lubricating grease evaporates and dries up, and it cannot play a lubricating role. The ball inside the bearing wears and falls out of the bearing after thermal expansion, causing the bearing function to lose, and the roller rotation stability drops sharply, causing the parts to deviate during operation, making it impossible for the upper loader to grab the parts normally, resulting in downtime. Frequent shutdowns are required to replace the bearing seat and bearings, and the upper bearing seat and the lower bearing seat are connected by many bolts. Therefore, the bolts need to be removed one by one when disassembling the bearing seat. This disassembly form is more troublesome. Therefore, a high-temperature resistant bearing seat mechanism of a heating furnace discharge roller is proposed. Summary of the invention

[0003] The utility model provides a high-temperature resistant bearing seat mechanism for a discharging roller of a heating furnace, which aims to solve the problem that grease must be added to the bearing inside the bearing seat to ensure its normal operation, but the grease and even the high-temperature grease will dry up and lose the lubricating effect in a continuous high-temperature environment, causing the bearing to wear and even damage, and the upper bearing seat and the lower bearing seat are connected by many bolts, so when disassembling the bearing seat, the bolts need to be removed one by one, and this disassembly method is relatively troublesome.

[0004] An embodiment of the utility model provides a high-temperature resistant bearing seat mechanism for a discharge roller of a heating furnace, comprising an upper bearing seat, a lower bearing seat being arranged at the bottom of the upper bearing seat, an installation cavity being provided on the sides of the upper bearing seat and the lower bearing seat which are close to each other, a plurality of cooling channels being provided on the upper bearing seat and the lower bearing seat, pipe joints being installed at both ends of each cooling channel, each of the pipe joints being connected to a liquid pipe, and a plurality of connecting components being installed between the upper bearing seat and the lower bearing seat.

[0008] By adopting the above technical solution, the upper bearing seat and the lower bearing seat can be connected using a connecting assembly, and the disassembly and connection operations of the upper bearing seat and the lower bearing seat are simplified, making them more convenient to use and facilitating subsequent use and replacement.

[0009] Furthermore, the connecting component also includes a sliding channel, a locking cavity, a sliding cavity, a second spring, and a pressure block.

[0010] By adopting the above technical solution, the positioning block can be limited by the positioning cavity, and the twist head will not rotate at will. In this way, during use, it is prevented from causing the twist head to move due to misoperation or external reasons, causing the slide bar to move, and then causing the limiting block to separate from the compression block, causing the compression block to lose its restriction and making the use of the graphene copper sleeve unstable.

[0011] Furthermore, the positioning block matches the sliding channel, and the sliding channel is divided into a straight section arranged on the wall of the assembly groove and a vertical arc section along the wall of the assembly groove. A through opening matching the sliding rod is opened on the lower bearing seat.

[0012] By adopting the above technical solution, the sliding channel can be used to allow the twist head to move initially, so that the slide rod and the limit block can slide and make way when squeezed, allowing the compression block to slide to the bottom of the limit block, and then the compression block is restricted by the limit block.

[0016] By adopting the above technical solution and utilizing the wave setting of the cooling channel, the contact area can be increased, which is beneficial to heat conduction for cooling. By utilizing the liquid pipe on one side for water inlet and the liquid pipe on the other side for water outlet, the coolant can pass through the upper bearing seat and the lower bearing seat to take away heat for cooling, which is beneficial to the continuous use of the upper bearing seat, the lower bearing seat and the graphene copper sleeve.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-6 The utility model embodiment proposes a high temperature resistant bearing seat mechanism for a discharge roller of a heating furnace, comprising an upper bearing seat 1, a lower bearing seat 2 is arranged at the bottom of the upper bearing seat 1, an installation cavity 3 is opened on the side where the upper bearing seat 1 and the lower bearing seat 2 are close to each other, a plurality of cooling channels 4 are opened on the upper bearing seat 1 and the lower bearing seat 2, pipe joints 5 are installed at both ends of each cooling channel 4, each pipe joint 5 is connected to a liquid pipe 6, and a plurality of connecting components are installed between the upper bearing seat 1 and the lower bearing seat 2.

[0031] The two installation cavities 3 are spliced ​​to form a cylindrical trough body, in which a graphene copper sleeve 7 is placed. The graphene copper sleeve 7 is installed using the trough body, and the material of the graphene copper sleeve 7 is graphene, which can withstand high temperatures and operate continuously and stably.

[0032] The connecting assembly includes a connecting rod 81, a compression block 82, a limit block 83, a spring 84, a sliding rod 85, a twist head 87, an operating piece 88 and a blocking block 812. The connecting rod 81 is installed at the bottom of the upper bearing seat 1, the compression block 82 is fixedly connected to the bottom of the corresponding connecting rod 81, the sliding rod 85 is slidably installed on the lower bearing seat 2, the limit block 83 is fixedly connected to one end of the sliding rod 85 close to the compression block 82, the spring 84 is sleeved on the outer side of the sliding rod 85, the twist head 87 is rotatably connected to the other end of the sliding rod 85, the operating piece 88 is installed on one side of the outer side of the twist head 87, the blocking block 812 is installed on the edge of the twist head 87, and an assembly groove 9 matching the twist head 87 is opened on the side of the lower bearing seat 2. The connecting assembly can be used to connect the upper bearing seat 1 and the lower bearing seat 2, and the disassembly and connection operations of the upper bearing seat 1 and the lower bearing seat 2 are simplified, which is more convenient to use and is conducive to subsequent use and replacement.

[0033] The connecting component also includes a sliding channel 89, a locking cavity 810, a sliding cavity 811, a second spring 813, and a pressure block 814. The sliding channel 89 is arranged on the groove wall of the assembly groove 9. The locking cavity 810 is arranged on the upper bearing seat 1 and the lower bearing seat 2 and is connected with the sliding channel 89. The sliding cavity 811 is connected with the locking cavity 810 and the sliding channel 89 and is arranged on the lower bearing seat 2. The pressure block 814 is slidably installed in the sliding cavity 811. The second spring 813 is installed between the pressure block 814 and the groove wall of the sliding cavity 811. The locking cavity 810 can be used to limit the locking block 812, and the twist head 87 will not rotate at will. In this way, during use, it is prevented from causing the twist head 87 to move due to misoperation or external reasons, causing the slide bar 85 to move, and then causing the limit block 83 to disengage from the pressure block 82, causing the pressure block 82 to lose its restriction, making the use of the graphene copper sleeve 7 unstable.

[0034] The positioning block 812 matches the sliding channel 89. The sliding channel 89 is divided into a straight section arranged on the wall of the assembly groove 9 and a vertical arc section along the wall of the assembly groove 9. A through opening matching the slide bar 85 is opened on the lower bearing seat 2. The sliding channel 89 can be used to allow the twist head 87 to move initially, so that the slide bar 85 and the limit block 83 can slide and make way when squeezed, so that the compression block 82 can slide to the bottom of the limit block 83, and then the compression block 82 is restricted by the limit block 83.

[0035] The side of the limiting block 83 that contacts the pressing block 82 is provided with an inclined surface, and the inclined surface is used to facilitate the contact between the limiting block 83 and the pressing block 82.

[0036] The cooling channel 4 is arranged in a wave shape. The liquid pipe 6 on one side of the liquid pipe 6 on the left and right sides is a water inlet pipe, and the liquid pipe 6 on the other side is a water outlet pipe. The wave arrangement of the cooling channel 4 can increase the contact area, which is beneficial to heat conduction for cooling. The liquid pipe 6 on one side is used to inlet water and the liquid pipe 6 on the other side is used to outlet water, so that the coolant passes through the upper bearing seat 1 and the lower bearing seat 2 to take away heat for cooling, which is beneficial to the continuous use of the upper bearing seat 1, the lower bearing seat 2, and the graphene copper sleeve 7.

[0037] The specific implementation method is as follows: when in use, the upper bearing seat 1 is connected with the lower bearing seat 2. At this time, the connecting rod 81 drives the compression block 82 to compress the limit block 83. Under the external force of compression, the limit block 83 begins to drive the slide bar 85 to slide, and at this time, the spring 1 84 is compressed and contracted by the external force until the compression block 82 moves to the bottom of the limit block 83. Under the restoring force of the spring 1 84, the limit block 83 slides on the top of the compression block 82, and the compression block 82 is limited by the limit block 83. Compared with using a large number of bolts, this will make the connection and disassembly of the upper bearing seat 1 and the lower bearing seat 2 more convenient and improve efficiency. Then the operating piece 88 and the twist head 87 can be rotated to allow the block 812 to move out of the sliding channel. The straight section of 89 is rotated 90° to the position of the locking cavity 810, and then the locking block 812 is allowed to enter the locking cavity 810, and the compression block 814 is used to compress and limit the locking block 812, thereby reducing the probability of the locking block 812 being separated from the locking cavity 810 due to accident or misoperation. This can avoid the rotation of the twist head 87, and then avoid the separation of the limit block 83 and the compression block 82 to release the restriction on the compression block 82, so that the upper bearing seat 1 and the lower bearing seat 2 are more firmly connected. When in use, let the coolant flow in from the liquid pipe 6 on one side and out from the liquid pipe 6 on the other side, so that the coolant passes through the upper bearing seat 1 and the lower bearing seat 2 to take away heat for cooling, so that the device can withstand high temperatures and operate continuously and stably.
