Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cutting equipment, and in particular to a thermal insulation rock wool quantitative cutting device. Background Art
[0002] Thermal insulation rock wool is a common building and industrial insulation material, primarily used to improve the thermal performance of buildings, pipelines, and equipment, while reducing energy loss. It is made by melting natural rocks (such as basalt and diabase) and spinning them into long, thin fibers. The resulting products include insulation boards, pipe shells, and blankets. Due to its excellent thermal insulation, sound insulation, and fireproofing properties, rock wool is widely used in construction, industry, shipping, and the chemical industry.

Only after cutting, the rock wool of uniform size can be used and combined in the future. At present, the cutting equipment of thermal insulation rock wool mostly adopts electric tools or flying knife discs for cutting. Although the end face is flat after cutting, due to the high content of particulate matter in the hardened rock wool, the cutting process will produce large dust and debris, resulting in poor air quality in the processing workshop, which greatly affects the working environment of the workers.

DETAILED DESCRIPTION
[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0023] Reference Figure 1-Figure 5A thermal insulation rock wool quantitative cutting device includes a first conveyor 1 for horizontal conveyance, a cutting table 2 spaced apart to the left of the first conveyor 1, and a second conveyor 3 spaced apart in front of the cutting table 2. The conveying surfaces of the first conveyor 1 and the second conveyor 3 are both arranged at the same height as the cutting table 2. The first conveyor 1 and the second conveyor 3 are both used for conveying the thermal insulation rock wool, while the cutting table 2 is used for cutting the thermal insulation rock wool. Specifically, the first conveyor 1 is used for horizontally conveying the thermal insulation rock wool to be cut, and can transport the left end of the thermal insulation rock wool to the cutting table 2. The second conveyor 3 is used for conveying the cut thermal insulation rock wool.
[0024] A longitudinal cutting section is formed between the cutting table 2 and the first conveyor 1, and a transverse cutting section is formed between the cutting table 2 and the second conveyor 3. Two vertical poles 4 are fixedly connected to the upper end of the body of the first conveyor 1 and the upper end of the cutting table 2. The four vertical poles 4 are distributed in a rectangular shape and the upper ends are fixedly connected to a device plate 5. A rectangular movement opening 6 is opened at the upper end of the device plate 5. The size of the movement opening 6 covers the cutting table 2, the longitudinal cutting section and the transverse cutting section. The upper end of the device plate 5 and the positions on both sides of the movement opening 6 are fixedly connected with a vertical plate 7, and a horizontally arranged first electric slide rail 8 is fixedly installed between the two vertical plates 7. The lower end of the first electric slide rail 8 is slidably connected to a first sliding member, and the lower end of the first sliding member is fixedly connected to a longitudinally arranged fixed plate 9. The front and rear ends of the device plate 5 are fixedly connected with two end blocks 10 distributed at intervals on the left and right, and a first slide bar 11 is fixedly connected between every two left and right opposite end blocks 10. The two first slide bars 11 are slidably sleeved with a first slider 12, and the upper ends of the two first sliders 12 are fixedly connected to the lower end of the fixed plate 9, and the lower end of the fixed plate 9 and the position in the movement opening 6 are fixedly installed with a longitudinally arranged second electric slide rail 13, and the lower end of the second electric slide rail 13 is slidably connected to a second sliding member, and the lower end of the second slide is fixedly installed with a downwardly arranged laser cutting head 14. The laser cutting head 14 can emit laser rays downward to perform laser cutting work. Laser cutting technology is a prior art and will not be explained here.
[0025] Specifically, the two first slide bars 11 play a supporting and limiting role for the fixed plate 9. Then, the fixed plate 9 can be driven by the first electric slide rail 8 to move horizontally above the movement opening 6, thereby driving the second electric slide rail 13 located in the movement opening 6 to move horizontally, and the laser cutting head 14 can be driven by the second electric slide rail 13 to move back and forth. Then, only with the cooperation of the first electric slide rail 8 and the second electric slide rail 13, the laser cutting head 14 can move freely above the cutting table 2, the longitudinal cutting zone, and the transverse cutting zone, so that the thermal insulation rock wool has a high cutting flexibility. In addition, the thermal insulation rock wool is cut by the laser cutting head 14, and the cut end face is flat. The cutting process does not generate dust and slag, and has extremely high cutting efficiency and cutting quality.
[0026] A first blocking mechanism is provided on the left side of the cutting table 2 , a second blocking mechanism is provided between the cutting table 2 and the second conveyor 3 , a third blocking mechanism is provided on the second conveyor 3 , and a pushing mechanism is provided on the rear side of the cutting table 2 .
[0027] The first blocking mechanism includes two first end plates 15 fixedly connected to the lower end of the cutting table 2 and arranged at intervals on the left and right. The two first end plates 15 are jointly rotatably connected with a first threaded rod 16, and a moving block 18 is threadedly sleeved on the first threaded rod 16. Two second sliding rods 17 symmetrically distributed about the first threaded rod 16 are jointly fixedly connected between the two first end plates 15. The two second sliding rods 17 both penetrate the moving block 18 horizontally and are slidably connected thereto. Two "["-shaped connecting frames 19 are provided on the left side of the cutting table 2. The lower ends of the two connecting frames 19 are fixedly connected to the moving block 18, and the upper ends of the two connecting frames 19 are jointly fixedly connected to a first baffle 20. The first baffle 20 is located on the cutting table 2. The right end of the first threaded rod 16 penetrates the first end plate 15 and is fixedly sleeved with a first bevel gear 21. The lower end of the cutting table 2 is fixedly connected to a vertically arranged mounting plate 22. A first motor 23 is fixedly installed on one side of the mounting plate. The driving end of the first motor 23 is fixedly sleeved with a second bevel gear 24, and the first bevel gear 21 is vertically meshed with the second bevel gear 24. The first motor 23 can directly drive the first threaded rod 16 to rotate under the transmission of the first bevel gear 21 and the second bevel gear 24, thereby driving the moving block 18 to move laterally under the limit of the two second slide bars 17. During the lateral movement of the moving block 18, the connecting frame 19 can be used to drive the first baffle 20 located on the cutting table 2 to move laterally, thereby adjusting the lateral position of the first baffle 20. Specifically, when the left end cup of the thermal insulation rock wool is conveyed to the cutting table 2 and is abutted against the first baffle 20, the first conveyor 1 stops conveying. At this time, the laser cutting head 14 can be controlled to move longitudinally in the longitudinal cutting section to complete the longitudinal cut of the thermal insulation rock wool. By adjusting the position of the first baffle 20, the laser cutting head 14 can easily cut the rock wool of a specified transverse length.
[0028] The second blocking mechanism includes a fixed box 25 fixedly connected to the front end of the vertical pole 4 located in the left front position. A lifting slot 26 is provided at the front end of the fixed box 25. A second threaded rod 27 is connected to the upper and lower inner walls of the lifting slot 26 and rotates together. A second motor 30 that drives the second threaded rod 27 to rotate is fixedly installed at the lower end of the fixed box 25. A lifting block 28 is slidably connected in the lifting slot 26. The second threaded rod 27 passes through the lifting block 28 and is threadedly connected thereto. One end of the lifting block 28 located outside the lifting slot 26 is fixedly connected to a horizontally arranged second baffle 29. The second baffle 29 is located above the horizontal cutting interval. The second motor 30 can drive the lifting block 28 to rise and fall vertically by driving the second threaded rod 27 to rotate, thereby controlling the vertical movement of the second baffle 29.
[0029] The pushing mechanism comprises two second end plates 31 fixedly connected at the rear end of the cutting table, a third threaded rod 32 rotatably connected between the two second end plates 31, a third sliding rod 33 fixedly connected between the two second end plates 31 and arranged in parallel with the third threaded rod 32, a first moving plate 35 sleeved on the third threaded rod 32 and the third sliding rod 33, the third threaded rod 32 being threadedly connected with the first moving plate 35 and the third sliding rod 33 being slidably connected with the first moving plate 35, a third motor 34 fixedly installed on the left second end plate 31 and configured to drive the third threaded rod 32 to rotate, an electric push rod 36 fixedly installed at the upper end of the first moving plate 35 and arranged in a longitudinal direction, a push plate 37 fixedly connected with the electric push rod 36 and arranged on the cutting table 2, and the electric push rod 36 being configured to drive the push plate 37 to move forward and backward, so as to push the longitudinally cut rock wool. The third motor 34 and the third threaded rod 32 are configured to adjust the transverse position of the push plate 37, so as to better push the rock wool according to the transverse length of the longitudinally cut rock wool.
[0030] Specifically, after the longitudinal cutting of the rock wool is completed, the second motor 30 controls the second baffle 29 to move downward and move to a position in front of the rock wool, and then the electric push rod 36 drives the rock wool on the cutting table 2 to move forward by the push plate 37, so that the front end of the rock wool abuts against the second baffle 29. Then, the laser cutting head 14 moves in the transverse cutting area, so that the front end surface of the rock wool is cut.
[0031] A collecting box 44 is arranged below the cutting table 2, and a plurality of air jet pumps 45 are fixedly installed at the front end of the second baffle 29 and arranged at intervals in a transverse direction. The air jet ends of the air jet pumps 45 are arranged downward. After the front end surface of the rock wool is cut, the second motor 30 controls the second baffle 29 to move upward and move to a position above the rock wool. Then, the electric push rod 36 drives the rock wool with the cut front end surface to move to the second conveyor 3. During the movement, the air jet pumps 45 jet air downward, so that the residual material on the cutting surface after cutting falls into the collecting box 44.
[0032] The third blocking mechanism includes two third end plates 38 fixedly connected to the right end of the second conveyor 3. A fourth threaded rod 39 is rotatably connected between the two third end plates 38. A fourth slide rod 40 is fixedly connected between the two third end plates 38. A second movable plate 41 is sleeved on the fourth threaded rod 39 and the fourth slide rod 40. The second movable plate 41 is threadedly connected to the fourth threaded rod 39 and slidably connected to the fourth slide rod 40. The second movable plate 41 extends above the second conveyor 3 and is fixedly connected to the left side of the third baffle 43. A fourth motor 42 is fixedly mounted on one of the third end plates 38 to drive the fourth threaded rod 39 to rotate. The fourth motor 42 can drive the fourth threaded rod 39 to rotate, causing the second movable plate 41 to move longitudinally, thereby adjusting the front-to-back position of the third baffle 43. By adjusting the position of the third baffle 43, the rock wool after front-end cutting is pushed onto the second conveyor 3, so that the front end of the rock wool abuts against the third baffle 43. Then, the laser cutting head 14 moves horizontally in the transverse cutting area to complete the transverse cutting of the rear end of the rock wool. At this time, the rock wool with the front and rear end faces cut is the required size. Only the fourth motor 42 and the electric push rod 36 need to cooperate to completely move the cut rock wool to the second conveyor 3 for transportation. Then, the first conveyor 1 can continue to transport. The cutting work is fully automated, and the cut rock wool is uniform in size, achieving an automatic and quantitative cutting effect.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
