[0002] FRP silencer is a device used for noise reduction and is widely used in ventilation ducts. Its principle is mainly to use porous sound-absorbing materials to reduce noise. The sound-absorbing materials are fixed on the inner wall of the air flow channel or arranged in the pipeline in a certain way to form a resistive silencer. When the sound wave enters the resistive silencer, part of the sound energy is converted into heat energy by friction in the pores of the porous material and dissipated, so that the sound waves passing through the silencer are weakened, achieving a better sound elimination effect.

[0036] See Figure Figure 3 , Figure 4The cutting device includes a first rotation driving assembly, which is used to perform the rotation process of the glass tube in the cutting state. The first rotation driving assembly includes a third driving part 17 arranged at the bottom of the bottom frame 1.

[0037] In addition, the base frame 1 is provided with several groups of rotating parts, which include a first fixed plate 20 fixedly connected to the upper surface of the base frame 1, and two groups of first auxiliary rollers 21 are sequentially arranged on the first fixed plate 20 along the direction perpendicular to the length of the glass tube, and a roller shaft is fixedly connected to the middle of the first auxiliary roller 21, and first ear seats are penetrated and connected to the bearings on both sides of the roller shaft, and first gears are fixedly connected to both ends of the roller shaft, and a conveyor belt 22 is drivingly connected to the first gear on the same side along the direction perpendicular to the length of the glass tube, and a round roller is drivingly connected to the middle of the conveyor belt 22, and a fixed shaft 23 is connected to the middle of the round roller by bearings, and the fixed shaft 23 penetrates and is fixed on the truss of the base frame 1 to ensure the contact stability of the fixed shaft 23 to the round roller, and the second rotating shaft 19 is located at the lower end of the conveyor belt 22 and is fixedly connected to the second gear, and the second gear forms a stable rotation transmission with the first gear, the conveyor belt 22, and the roller shaft on the same vertical reference plane;

[0038] When the third driving unit 17 is started, its output end drives the second rotating shaft 19 to rotate through gear meshing. When the second rotating shaft 19 rotates, the conveyor belt 22 is driven to operate in the same frequency and direction through the first gear. When the conveyor belt 22 drives the second gear connected thereto to rotate, the first auxiliary roller 21 in contact with the glass tube rotates in the same direction and speed, so that the glass tube body rotates, and the first pressing roller 12 and the second pressing roller 13 also rotate to assist the glass tube to rotate effectively.

[0039] In addition, the first fixed plate 20 may also be provided with a second conveying portion 42 , which will be discussed below and will not be described here, and can realize the rotation process of the first auxiliary roller 21 .

[0040] It should be noted that a pushing mechanism is provided at one end of the glass tube located at the feeding end. After a section of the glass tube is cut, the next section of the glass tube to be cut is moved to the cutting position for the corresponding cutting process. The pushing mechanism can also be replaced manually, which is called a pushing process.

[0041] refer to Figure 5 , Figure 6 as well as Figure 7The cutting device further comprises a liquid spraying assembly, which is used for performing liquid spraying in the cutting process. Specifically, the liquid spraying assembly comprises a liquid tank 25, wherein the liquid tank 25 stores cutting fluid, and a liquid pump 26 is connected to a pipeline inside the liquid tank 25, and a first liquid spraying pipe 24 is connected to the other end of the pipeline of the liquid pump 26, wherein the first liquid spraying pipe 24 is a retractable structure, and the pipe opening of the first liquid spraying pipe 24 is arranged toward the bottom of the cutting knife 7, and a first control valve is arranged on the pipe connected to the first liquid spraying pipe 24. When the glass tube is cut, the liquid pump 26 is started, and the first control valve is opened, so that the pipe opening of the first liquid spraying pipe 24 is aligned with the cutting position to spray the cutting fluid, so as to achieve lubrication, cooling, cleaning and the like, so as to improve the cutting quality;

[0042] In addition, the bottom box 16 is located below the cutting knife 7 and the nozzle of the first spray pipe 24, and is used to collect cutting fluid. A discharge pipe is connected to the bottom of the bottom box 16, which is used to discharge the cutting fluid and the waste contained therein in time for subsequent filtration and recycling, which will not be elaborated here.

[0043] refer to Figure 8 A group of second moving parts 27 are installed on the upper surface of the bottom frame 1 below the third bracket 4. The group of second moving parts 27 are arranged parallel to the length direction of the glass tube, and the group of second moving parts 27 are arranged in a straight line direction. The specific arrangement refers to the arrangement of the first moving part 6 mentioned above. A group of second moving parts 27 are connected to the first moving end close to the second bracket 3 and are provided with a first moving plate 30. A notch is provided on the surface of the first moving plate 30. A fourth telescopic part 29 is arranged below the first moving plate 30. A positioning plate 31 is fixedly connected to the top of the output end of the fourth telescopic part 29, which is used to resist one side of the glass tube when the glass tube is cut to achieve a fixed-length cutting effect. The positioning plate 31 is moved up and down in the notch by controlling the telescopic movement of the fourth telescopic part 29, so as to realize the process switching of limiting and separating and conveying the glass tube;

[0044] The cutting device is signal-connected to a control terminal, which is usually arranged in the form of a console or a control panel, not shown in the figure. A data processor is arranged in the control terminal for setting and adjusting the cutting program and collecting and analyzing the cutting data during the cutting process to improve the cutting quality of the glass tube.

[0045] Specifically, the cutting program is started. During the cutting process, the glass tube to be cut is pushed to contact the positioning plate 31 extending out of the notch of the first movable plate 30, and the cutting length is determined. The output ends of the first telescopic part 9 and the second telescopic part 10 respectively drive the first pressing roller 12 and the second pressing roller 13 to move downward and contact the upper surface of the glass tube. Then, the first rotating drive assembly is started, and the second driving part 15 connected to the first pressing roller 12 and the second pressing roller 13 is also started synchronously to perform the limiting and self-rotation process of the glass tube to be cut. Subsequently, the first movable part 6 is started and drives the cutting knife 7 to move to the cutting position. The first driving part 8 is also started synchronously to realize the rotation and downward movement of the cutting knife 7, and the cutting of the glass tube is completed during the self-rotation process of the glass tube.

[0046] During the cutting process, the liquid spraying assembly sprays liquid at a preset spraying flow rate q on the cutting point between the glass tube and the cutting knife 7, and the glass tube rotates through a preset number of rotations c, thereby completing the preset glass tube cutting.

[0047] Accordingly, when the glass tube is pushed, the first scanning unit 5 first measures the distance of the vertex position of the upper surface of the glass tube and acquires data, and adjusts the cutting position of the cutting knife 7 in real time according to the vertex position of the glass tube and the pre-input tube wall thickness, so as to ensure that the cutting knife 7 can effectively cut glass tubes with a wider range of diameters and lengths; and adjusts the limit heights of the first pressing roller 12 and the second pressing roller 13 accordingly;

[0048] During the cutting process, the first scanning unit 5 can also photograph the surface of the glass tube and monitor the surface cracks. When the surface of the glass tube is scanned to be cracked, the cutting process is suspended after the cutting of the glass tube to be cut is completed. In addition to removing the glass segment involved in the crack, the rotation speed of the cutting knife 7 is adjusted according to the obtained crack time point. The longer the time, the smaller the rotation speed of the cutting knife 7. In addition, the spray flow rate of the spray component is adjusted accordingly to adapt to the new rotation speed of the cutting knife 7. Through the above settings, it is possible to cut glass tubes using a multi-path long range, and it is also possible to monitor the crack data of the glass tube in real time, thereby adjusting the corresponding cutting data to improve the intelligent use of the device.

[0049] After the glass tube is cut to length, the positioning plate 31 moves to below the notch under the action of the fourth telescopic portion 29, and the glass tube moves the cut end face of the glass tube to above the notch under the action of the pushing process to perform the subsequent end face detection process.

[0050] Furthermore, the cutting device further comprises a second rotation driving assembly, which is used for rotating and conveying the glass tube after the segmentation. The glass tube after the segmentation is hereinafter referred to as the segmented glass tube. When the segmented glass tube is moved to the placement box, the segmented glass tube is placed by means of a manual or separately provided downwardly inclined conveying plate. The second rotation driving assembly comprises a second moving plate 28 connected to the second moving end of the second moving part 27, the bottom of the third bracket 4 is fixed to the second moving plate 28, and the third pressing roller 14 is used for cooperating with the limited rotation of the segmented glass tube.

[0051] refer to Figure 7 , Figure 8 and Fig.10 , the second auxiliary rollers 41 are arranged on both sides of the segmented glass tube on the upper surface of the second movable plate 28, the middle part of the second auxiliary roller 41 passes through and is fixedly connected with a central axis, the two ends of the central axis pass through and are bearing-connected with second ear seats, and a second conveying part 42 is connected and arranged between the second ear seats on the same side, the second conveying part 42 includes a fourth driving part, a conveyor belt and a gear structure connected to the fourth driving part, and the gears are respectively arranged at the output end of the fourth driving part and one end of the central axis on the same side. When cutting the next segment of the glass tube, the first pressing roller 12 and the second pressing roller 13 move up a distance, and the positioning plate 31 as described above moves down, and the third pressing roller 14 descends to contact with the upper surface of the glass tube, and the pushing process starts. During the pushing process, the segmented glass tube is moved onto the second auxiliary roller 41, and then the second movable plate 28 and the third bracket 4 move a distance in the direction of unloading under the action of the second movable part 27, so that the end face of the glass tube to be cut and the end face of the segmented glass tube to be cut are separated by a distance, which is set as the end face detection distance;

[0052] After the segmented glass tube moves to the end face detection distance, the second driving unit 15 connected to the third pressing roller 14 and the second conveying unit 42 are started to perform synchronous rotation of the segmented glass tube and the glass tube to be cut, and then perform synchronous detection.

[0053] refer to Figure 7 , Fig. 9 as well as Fig.11 A support column 32 is fixedly installed on one side of the first movable plate 30, and the support column 32 is configured as a retractable structure. A third ear seat 33 is fixed on the top of the support column 32, and a first transmission part 34 is provided on one side of the third ear seat 33. The first transmission part 34 includes a fifth driving part and a transmission belt and a gear structure connected to the fifth driving part. The output end of the first transmission part 34 passes through and is connected to the third ear seat 33 by a bearing. The output end of the first transmission part 34 is connected to a detection component;

[0054] The detection assembly includes a first connecting rod 35 fixedly connected to the output end of the first transmission part 34, and the other end of the first connecting rod 35 is fixedly connected to a third connecting rod 37 and a second connecting rod 36 respectively. Fig. 9 The figure shows the initial state of the detection assembly, the angle between the third connecting rod 37 and the second connecting rod 36 is not less than 90°, and the third connecting rod 37 and the second connecting rod 36 are located outside the glass tube, and the second connecting rod 36 is shorter than the third connecting rod 37;

[0055] Furthermore, a second scanning unit 40 is installed at the other end of the second connecting rod 36, and the second scanning unit 40 is used to scan the burrs of the end faces of the glass tube to be cut and the end faces of the segmented glass tube that are close to each other. The other end of the third connecting rod 37 is fixedly connected to a connecting block 38 by a pin, and the connecting block 38 is arranged in a convex shape. The end face detection distance is greater than the length of the connecting block 38 toward the glass tube. An abrasive part 39 is arranged on the end face of the connecting block 38 toward the glass tube. The abrasive part 39 is preferably wet sandpaper. The abrasive part 39 is fixed to the connecting block 38 by a pin or a thread, which can facilitate the installation and timely replacement of the abrasive part 39; a second spray pipe 43 is installed above the third connecting rod 37, and the nozzle of the second spray pipe 43 is arranged in a spray shape and is arranged to align with the abrasive part 39. The other end of the second spray pipe 43 is connected to the first spray pipe 24 through a three-way valve, and a second control valve is arranged on the second spray pipe 43 to control the opening and closing of the second spray pipe 43.

[0056] According to the above-mentioned glass tube, the end face of the cut glass tube is moved to the top of the notch under the pushing process, that is, the segmented glass tube is also moved to the second auxiliary roller 41, and the third pressing roller 14 is lowered to contact with the upper surface of the segmented glass tube to clamp the segmented glass tube, and then the second moving part 27 is started, and the second moving plate 28 drives the segmented glass tube to move the corresponding end face detection distance, and then the segmented glass tube is rotated synchronously with the glass tube to be cut;

[0057] During the rotation process, the detection component detects the burr data of the cut end surface. First, the output end of the first transmission part 34 drives the second connecting rod 36 to rotate to an angle facing the middle of the glass tube. The second scanning part 40 starts scanning to collect the image of the burr data of the two end surfaces rotating one circle, and obtains the area data of the burr amount at each end surface. The end surface burr amount is recorded as S. ij , 1≤i≤n, i is an integer, j is 1 or 2, i is the number of the segmented glass tube, j represents the specific end face of the segmented glass tube with the serial number i, j is 1 or 2, 1 represents the first cut end face of the segmented glass tube for end face detection, and 2 represents the second cut end face of the segmented glass tube for end face detection;

[0058] It should be noted that the burr amount of the two end faces of the first segmented glass tube to be cut should be recorded as S 11 , S 12 , segmented glass tube end surface S 11If the cutting knife 7 is not cut, there is no need to collect burr data. If the end face of the glass tube is pre-processed before the fixed length cutting of the glass tube, that is, one end of the first segmented glass tube is cut for a certain length before cutting, it is necessary to perform S during the cutting. 11 The data is collected separately; by analogy, the collection of the end face burr data of the last section of the glass tube will be determined based on whether the end face has been cut.

[0059] Furthermore, S 12 and S 21 Recorded as the first end face detection group, S 22 and S 31 Recorded as the second end face detection group, S 32 and S 41 Recorded as the third end face detection group, and so on, S i2 and S （i+1）1 Denoted as the i-th end face inspection group;

[0060] The second scanning unit 40 transmits the collected data of the i-th end surface detection group to the control end, and the control end i2 and S （i+1）1 The difference and sum are calculated, and the difference between the two is recorded as the end face burr difference △S i The sum of the two is recorded as the end face burr sum value ∑S i , △S i =S i2 -S （i+1）1 ,∑S i =S i2 +S （i+1）1 .

[0061] According to △S i The size range determines whether to pre-deburr one of the end faces, and sets the difference ±s to be ignored; when -s≤△S i ≤+s, indicating that the burr amounts on the two opposite end faces of the end face detection group are close to each other, and there is no need for separate pre-deburring treatment. The two end faces are subjected to a synchronous deburring process, that is, the first moving end and the second moving end of the second moving part 27 respectively drive the abrasive part 39 and the segmented glass tube to move L1 and L2 distances, and then are located at the deburring position, and the two sides of the abrasive part 39 can contact the two end faces respectively. After the movement, the first conveying part 34 drives the third connecting rod 37 to rotate to an angle at which the abrasive part 39 can contact the two end faces. When the glass tube is rotating and the segmented glass tube is driven by the second conveying part 42, the cutting device is used to complete the preliminary deburring integrated process after the end face burr detection, thereby saving the time occupied by the subsequent initial grinding of the glass tube;

[0062] When △S i When <-s, it means S （i+1）1The burr amount of the corresponding end face is large, according to the required △S i The absolute value of △S is obtained by controlling the first moving end of the second moving part 27 to move the first moving plate 30 toward the end face of the glass tube being cut by a certain distance L3. i The absolute value of is positively correlated. After the movement, the first conveying part 34 drives the third connecting rod 37 to rotate to the angle of contact with the end surface, and performs a pre-deburring process on the contacted end surface, so that the burrs on the two end surfaces tend to be close. After the set operation time, the first moving end and the second moving end of the second moving part 27 respectively drive the abrasive part 39 and the segmented glass tube to move and make the two sides of the abrasive part 39 contact with the two end surfaces at the deburring position, so as to perform the above-mentioned synchronous deburring process;

[0063] When △S i >+s, indicating S i2 The burr amount of the corresponding end face is large, according to the required △S i The first moving end of the second moving part 27 controls the first moving plate 30 to move toward the end surface of the segmented glass tube by a certain distance L4. The moving distance L4 is related to △S i Positive correlation, then repeat the above-mentioned first transmission part 34 to drive the third connecting rod 37 to rotate to the angle where the abrasive part 39 contacts the end face, and perform a pre-deburring process on the contacted end face, after running for a set time so that the burr amounts on the two end faces tend to be similar, the first moving end and the second moving end of the second moving part 27 respectively drive the abrasive part 39 and the segmented glass tube to move and make the two sides of the abrasive part 39 contact with the two end faces at the deburring position, so as to perform the above-mentioned synchronous deburring process, so that the synchronous initial grinding process is carried out on the basis of the pre-deburring treatment, saving the time of separate deburring.

[0064] Furthermore, according to ∑S i The accumulated value of is used to obtain the wear degree of the abrasive part 39. Considering the deburring effect of the abrasive part 39 after multiple uses, the corresponding moisturizing treatment will be performed according to the wear degree, and the abrasive part 39 will be replaced in time according to the wear degree;

[0065] Start accumulating the sum from ∑S1, and set the value to S p When the wear degree is normal, it means that the abrasive part 39 needs to be moistened to ensure the deburring effect, that is, when the abrasive part 39 is in the deburring process, the second liquid spraying pipe 43 will spray liquid to moisten the abrasive part 39;

[0066] When accumulated to S max When the wear degree is high, after the current deburring process is completed, the abrasive part 39 is replaced after the third connecting rod 37 rotates to the initial position to perform the subsequent deburring process;

[0067] After the abrasive part 39 is replaced, the sum of the end face burrs is accumulated again, and the above steps are repeated to complete the integrated process of cutting and deburring the glass tube;

[0068] The first bracket 1 is provided with a liquid collecting box below the second liquid spraying pipe 43 to collect the liquid sprayed in the form of a liquid fluid, and at the same time has a certain dust reduction effect on dust during the deburring process, thereby improving the cleanliness of the operating environment.
