Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, and more specifically, it relates to an anti-lock structure for grinding machines. Background Technology

[0002] Insufficient lubrication can cause gears and other transmission components in a grinding machine to seize up due to excessive friction during operation. Therefore, operators need to regularly add lubricating oil to the gears and other transmission components to ensure that they are adequately lubricated and reduce the likelihood of the grinding machine seizing up.

[0003] Based on the above, when adding lubricating oil, the operator needs to first open the mounting box of the transmission component, then evenly drip the lubricating oil onto the outside of the transmission component, and then put the mounting box back in place after adding the lubricating oil. This process takes a long time, which not only increases the workload of the operator but also affects the efficiency of adding lubricating oil. It also leads to a longer downtime of the grinding machine, affecting the working efficiency of the grinding machine. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an anti-lock structure for a grinding machine, which solves the problem that adding lubricating oil takes a long time, resulting in a heavy workload for workers, reduced lubricating oil addition efficiency, and prolonged downtime of the grinding machine, thus affecting its working efficiency.

[0005] The purpose and effect of this utility model's anti-lock structure for a grinding machine are achieved through the following specific technical means:

[0006] A grinding mill anti-lock structure includes a grinding mill base, temperature warning components, audible and visual alarms, a first drive shaft, a second drive shaft, a material grinding roller, a monitoring component, a drive gear, a lubrication component, and an oil-absorbing sponge block.

Oil storage chambers are provided on both the left and right sides of the grinding mill base. Two audible and visual alarms are provided, each bolted to the left and right sides of the grinding mill base. Two first drive shafts are provided, each rotatably connected to the left and right sides of the grinding mill base. The base has two second drive shafts, each rotatably connected to the left and right sides of the grinding machine base. Multiple material grinding rollers are evenly distributed and rotatably connected to the upper part of the grinding machine base. Two monitoring components are located on the left and right sides of the grinding machine base. Multiple drive gears are fixedly connected to the front or rear sides of the multiple material grinding rollers. Two lubrication components are located on the left and right sides of the grinding machine base. Two oil-absorbing sponges are attached to the inner sides of the oil storage chambers on the left and right sides of the grinding machine base.

[0007] Furthermore, the lubrication assembly includes an oil reservoir sealing plug and a reset scroll spring; two oil reservoir sealing plugs are provided, and the two oil reservoir sealing plugs are respectively threaded to the left and right sides of the grinding machine base; two reset scroll springs are provided, and the two first drive shafts are elastically connected to the grinding machine base through the two reset scroll springs.

[0008] Furthermore, the lubrication assembly also includes incomplete transmission gears and compression cams; four incomplete transmission gears are provided, with a smaller diameter incomplete transmission gear fixedly connected to the outer side of each of the first transmission shafts, and a larger diameter incomplete transmission gear fixedly connected to the inner side of each of the two active transmission gears located above the first transmission shafts; two compression cams are provided, with the two compression cams fixedly connected to the outer sides of the two first transmission shafts respectively.

[0009] Furthermore, the lubrication assembly also includes a limiting extrusion plate and a pressure-bearing sponge block; two pressure-bearing sponge blocks are provided, and the two pressure-bearing sponge blocks are respectively bonded to the lower part of the two oil-absorbing sponge blocks, and both pressure-bearing sponge blocks are in contact with the drive transmission gear; two limiting extrusion plates are provided, and the two limiting extrusion plates are respectively fixedly connected to the outer side of the two pressure-bearing sponge blocks, and the left and right sides of the limiting extrusion plates are both arc-shaped structures.

[0010] Furthermore, the monitoring component includes a grinding roller protective cover and a temperature sensor; the grinding roller protective cover is bolted to the upper part of the grinding machine base; two temperature sensors are provided, and the two temperature sensors are respectively fixedly connected to the inner side of the two temperature warning components, and the control circuits of the two temperature sensors are respectively connected in series with the control circuits of the two audible and visual alarms.

[0011] Furthermore, the monitoring component also includes a synchronous transmission component and a cooling fan blade; the synchronous transmission component is a synchronous belt transmission mechanism, and two synchronous transmission components are provided, with the two first transmission shafts being connected to the two second transmission shafts through the two synchronous transmission components; two cooling fan blades are provided, and the two cooling fan blades are respectively fixedly connected to the outside of the two second transmission shafts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses a temperature warning device and an audible and visual alarm to alert workers when the grinder's temperature is too high, allowing them to shut it down promptly. This effectively prevents gear deformation due to overheating from prolonged operation, thus avoiding the seizing of transmission components. A protective cover for the grinding rollers prevents debris from falling onto them and causing jamming between rollers, significantly improving the grinder's safety. A pressure cam automatically adds lubricating oil to the drive gear by squeezing a pressurized sponge block, ensuring sufficient lubrication and preventing gear jamming due to excessive friction. This eliminates the inconvenience of manual lubrication, reducing worker workload, saving considerable time, and increasing lubrication efficiency. It also shortens downtime and improves the grinder's overall efficiency. Attached Figure Description

[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0030] Example 1:

[0031] As attached Figure 1 To be continued Figure 6 As shown:

[0032] This utility model provides an anti-lock structure for a grinding mill, including a grinding mill base 1, temperature warning components 2, audible and visual alarms 3, a first drive shaft 4, a second drive shaft 5, a material grinding roller 6, a monitoring component, and a drive gear 7; two temperature warning components 2 are provided, and the two temperature warning components 2 are respectively fixedly connected to the left and right sides of the grinding mill base 1. The outer side of both temperature warning components 2 is coated with temperature-sensitive color-changing paint, and the temperature warning components 2 are made of thermally conductive material; oil storage chambers are opened on both the left and right sides of the grinding mill base 1; two audible and visual alarms 3 are provided, and the two audible and visual alarms 3 are respectively bolted to the grinding mill base. The base 1 has two first drive shafts 4, which are rotatably connected to the left and right sides of the grinding machine base 1, respectively; two second drive shafts 5, which are rotatably connected to the left and right sides of the grinding machine base 1, respectively; multiple material grinding rollers 6, which are evenly distributed and rotatably connected to the upper part of the grinding machine base 1; two monitoring components, which are respectively located on the left and right sides of the grinding machine base 1; and multiple drive gears 7, which are fixedly connected to the front or rear sides of the multiple material grinding rollers 6, respectively.

[0033] The monitoring components include a grinding roller protective cover 101 and a temperature sensor 201. The grinding roller protective cover 101 is bolted to the upper part of the grinding machine base 1. There are two temperature sensors 201, which are fixedly connected to the inner side of two temperature warning devices 2 respectively. The control circuits of the two temperature sensors 201 are connected in series with the control circuits of the two audible and visual alarms 3 respectively.

[0034] The monitoring component also includes a synchronous transmission component 404 and a cooling fan blade 501. The synchronous transmission component 404 is a synchronous belt transmission mechanism. Two synchronous transmission components 404 are provided. The two first transmission shafts 4 are connected to the two second transmission shafts 5 through the two synchronous transmission components 404. Two cooling fan blades 501 are provided. The two cooling fan blades 501 are respectively fixedly connected to the outside of the two second transmission shafts 5.

[0035] The specific usage and function of this embodiment are as follows: When the material grinding roller 6 and the active transmission gear 7 drive the first transmission shaft 4 to rotate, the second transmission shaft 5 rotates with the first transmission shaft 4 under the action of the synchronous transmission component 404. When the second transmission shaft 5 rotates, it will drive the cooling fan blades 501 to rotate and generate wind to help the active transmission gear 7 dissipate heat. When the temperature inside the grinder is high, the temperature warning component 2 will change color to remind the staff to shut down the grinder in time. If the staff does not notice the color change of the temperature warning component 2, the temperature inside the grinder will continue to rise. At this time, the temperature sensor 201 will send a signal to the audible and visual alarm 3 to activate the audible and visual alarm 3 to warn the staff. The grinding roller protective cover 101 can prevent debris from falling onto the material grinding roller 6.

[0036] Example 2:

[0037] As attached Figure 3 To be continued Figure 6 As shown:

[0038] Based on Embodiment 1, it also includes a lubrication component and an oil-absorbing sponge block 8; two lubrication components are provided, and the two lubrication components are respectively provided on the left and right sides of the grinding machine base 1; two oil-absorbing sponge blocks 8 are provided, and the two oil-absorbing sponge blocks 8 are respectively attached to the inner side of the oil storage cavity on the left and right sides of the grinding machine base 1.

[0039] The lubrication assembly includes an oil reservoir sealing plug 102 and a reset scroll spring 402. Two oil reservoir sealing plugs 102 are provided, and the two oil reservoir sealing plugs 102 are threadedly connected to the left and right sides of the grinding machine base 1, respectively. Two reset scroll springs 402 are provided, and the two first drive shafts 4 are elastically connected to the grinding machine base 1 through the two reset scroll springs 402.

[0040] The lubrication assembly also includes incomplete transmission gears 401 and compression cams 403. There are four incomplete transmission gears 401, with a smaller diameter incomplete transmission gear 401 fixedly connected to the outer side of each first transmission shaft 4, and a larger diameter incomplete transmission gear 401 fixedly connected to the inner side of each of the two drive transmission gears 7 located above the first transmission shaft 4. There are two compression cams 403, with the two compression cams 403 fixedly connected to the outer side of each of the two first transmission shafts 4.

[0041] The lubrication assembly also includes a limiting extrusion plate 801 and a pressure-bearing sponge block 802. There are two pressure-bearing sponge blocks 802, which are respectively bonded to the lower part of two oil-absorbing sponge blocks 8, and both pressure-bearing sponge blocks 802 are in contact with the drive transmission gear 7. There are two limiting extrusion plates 801, which are respectively fixedly connected to the outside of the two pressure-bearing sponge blocks 802, and both the left and right sides of the limiting extrusion plates 801 are arc-shaped structures.

[0042] The specific usage and function of this embodiment are as follows: When the drive gear 7 rotates, the larger diameter incomplete drive gear 401 will rotate along with the drive gear 7. When the larger diameter incomplete drive gear 401 meshes with the smaller diameter incomplete drive gear 401, the larger diameter incomplete drive gear 401 will drive the smaller diameter incomplete drive gear 401 and the first drive shaft 4 to rotate. The rotation of the first drive shaft 4 will drive the compression cam 403 to rotate, causing the compression cam 403 to compress the limiting compression plate 801. When the limiting compression plate 801 is compressed, it will compress the compressed sponge block 802. This forces the lubricating oil in the compressed sponge block 802 to flow onto the drive gear 7, thus lubricating the drive gear 7. When the larger diameter incomplete drive gear 401 no longer meshes with the smaller diameter incomplete drive gear 401, the reset spiral spring 402 drives the first drive shaft 4 to reset. The oil-absorbing sponge block 8 will continuously transport the lubricating oil in the oil storage chamber to the compressed sponge block 802. After the lubricating oil is used up, the oil storage chamber sealing plug 102 can be removed and lubricating oil can be added to the oil storage chamber. After adding, the oil storage chamber sealing plug 102 can be screwed back to its original position to seal the oil storage chamber.
