Description

Technical Field

[0001] The present invention belongs to the technical field of building materials, and specifically relates to a new type of wall caulking material and its preparation equipment. Background Art

[0002] During housing construction, windows for installing doors and windows are left on the wall. Generally, the left windows are larger than the outer periphery of the door and window frames. The purpose is to facilitate the installation of doors and windows, and the gaps between the door and window frames and the windows are filled with building materials. However, for a long time, water leakage frequently occurs between building doors and windows and the windows. One reason is due to construction problems, and the other is due to the caulking and sealing materials.

[0003] Among them, the selection and quality of the caulking and sealing materials are one of the main reasons affecting the quality of door and window projects. Currently, the most commonly used caulking materials for filling the gaps between doors and windows and the walls are cement mortar, polyurethane foam, etc. Due to the poor bonding force and deformation ability of ordinary cement mortar, it is easy to shrink and crack, and leakage is likely to occur.

[0004] Most of the caulking mortars on the market are currently cement mortars. Ordinary cement mortar has a certain flexural and compressive strength and good reinforcement performance for the window frames, but its deformation ability and bonding ability are poor, and it is easy to crack and cause leakage. Moreover, in recent years, with the application of new technologies such as aluminum alloy for doors and windows and oxidation processes, as well as the improvement of people's requirements for houses, higher requirements have been put forward for the performance of caulking filling mortars.

[0005] Therefore, the present invention provides a preparation method and preparation equipment for a new type of wall caulking material. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A preparation method for a new type of wall caulking material according to the present invention, wherein the new type of wall caulking material comprises the following raw materials in parts by weight: 42.5R cement 30 - 40 parts; Cork bark particles 10 - 20 parts; Machine-made sand 30 - 40 parts; Quartz sand 20 - 30 parts; Rapid hardening sulphoaluminate cement 5 - 10 parts; The diameter of the cork bark particles is 3 - 5 mm; The preparation method for the new type of wall caulking material comprises the following steps: S1: Raw material preparation. Prepare the raw materials of Quercus variabilis Blume bark particles. Use the new type of wall caulking material preparation equipment to punch out the raw materials of Quercus variabilis Blume bark particles from the raw materials of Quercus variabilis Blume bark, then crush them, and then collect them centrally and store them dry for later use; S2: Preparation of materials. Transport the raw materials to the construction site for window and door filling. Before construction, store the raw materials dry and sealed; S3: Prepare the new type of wall caulking material at the construction site. Put 42.5R cement, machine-made sand, quartz sand and rapid hardening sulphoaluminate cement into the Shuanglong mixing blender, add water and stir for 1 - 2 minutes, then put the Quercus variabilis Blume bark particles into the Shuanglong mixing blender and stir again for 1 - 2 minutes to obtain the new type of wall caulking material.

[0008] Preferably, the new type of wall caulking material also includes the following raw materials in weight components: Cellulose ether 0.1 - 0.2 parts; Thixotropic agent 0.7 - 0.9 parts; Water repellent 0.8 - 1.5 parts; The cellulose ether is hydroxypropyl methyl cellulose; the thixotropic agent is a composite of bentonite and starch ether in a ratio of 3:1; the water repellent is a composite of silicone powder and rubber powder in a ratio of 1:3.

[0009] A preparation device for a new type of wall caulking material, which is adapted to the above-mentioned preparation method of a new type of wall caulking material. The preparation device for the new type of wall caulking material includes a support plate, a punching mechanism, and a feeding mechanism; the feeding mechanism includes two upper and lower guide rollers, the ends of the guide rollers are rotatably connected to the support plate, a double-layer guide plate is provided on one side of the guide rollers, one edge of the guide plate is close to the gap between the two guide rollers, and the punching mechanism is above the guide plate. The punching mechanism includes a cross plate, a cylinder, and a connecting plate; the cross plate is fixedly connected to one side of the support plate, a plurality of cylinders are fixedly connected to the cross plate, the piston rods of the cylinders vertically penetrate the cross plate downward and are fixedly connected to the connecting plate, and a punching knife and a plurality of punching rods are fixedly connected to the lower surface of the connecting plate; the punching rods are fixedly connected to the connecting plate in a row, the punching rods are close to the guide rollers, the punching rods vertically penetrate through the through holes opened on the guide plate, and one side of the punching rods is the punching knife, and the lower edge of the cutting edge of the punching knife vertically penetrates through the strip-shaped holes opened on the guide plate; the ends of the guide rollers are connected to a motor and drive the guide rollers to rotate clockwise. The tree bark is put between the guide rollers, and then the guide rollers rub the bark into the guide plate. At this time, the cylinder drives the punching rods and the punching knife to move up and down alternately through the connecting plate. The punching rods punch holes in the bark, and then push it to continue moving forward. The punching knife cuts the bark into strips. At this time, each strip-shaped bark has holes. Then the strip-shaped bark is broken and crushed into granular form. Finally, through screening, particles with a diameter of 3-5 mm are selected; the guide rollers push the bark into the guide plate, and the bark is restricted. Then, through the punching rods, holes are punched, so that the tree bark particles have holes. Even if the strip-shaped bark is broken into granular form, there are still holes or incomplete holes on the surface of the particles. After these holes are mixed with the slurry, the solidified slurry can still wrap the tree bark particles, and can still improve the adhesion and solidity inside the new type of wall caulking material.

[0010] Preferably, the other side of the guiding roller is a feeding mechanism; the feeding mechanism includes upper and lower clamping plates. One end of the clamping plates is close to the middle position between the two guiding rollers. A plurality of strip-shaped through slots are evenly opened in the width direction of the clamping plates. The through slots are rotatably connected to rotating rollers. Chain wheels are provided at the ends of the rotating rollers. The chain wheels on the same side of the clamping plates are connected by chain drive; when the guiding roller rotates, the tree bark is pushed into the guiding plate through the friction force with the tree bark, and this makes the feeding action of the tree bark relatively dangerous. Therefore, a feeding mechanism is provided. The staff horizontally places the tree bark at the entrance of the clamping plates. The rotating rollers rotate through the cooperation of the chain wheels and the chains. One of the chain wheels is connected to the output end of an external motor. The rotating rollers rotate to rub the tree bark between the clamping plates, and then the subsequent rotating rollers rub the tree bark forward and push it into the guiding roller; the setting of the rotating rollers not only rubs the tree bark forward and reduces the safety risk of feeding, but also removes the sundries on the surface of the tree bark. Debris and rotten substances on the surface of the tree bark are squeezed and rubbed into pieces when passing through the rotating rollers. Some debris falls through the through slots, and some debris is separated during the later screening, reducing the mixing of debris into the mortar and affecting the adhesiveness and curing strength of the mortar.

[0011] Preferably, the four right-angle positions of the clamping plates are connected together by tension springs up and down, and a screw rod passes through the inner circle of the tension spring. The end of the screw rod passes through the four right-angle parts of the clamping plates and is limited on the clamping plates by nuts; the thicknesses of the tree barks are different. By setting the clamping plates with adjustable upper and lower spacing, the surface of the rotating rollers can effectively press on the surface of the tree bark. When a thicker tree bark is placed between the clamping plates, the clamping plates move away from each other and stretch the tension springs. When a thinner tree bark is placed between the clamping plates, the tension springs pull and squeeze the tree bark to ensure that the tree bark is rubbed forward and the attachments on the surface of the tree bark are cleaned off.

[0012] Preferably, an air duct is opened inside the clamping plates. The air inlet end of the air duct is connected to an external air supply pump through a pipeline, and the air outlet of the air duct is located on the opposite surfaces of the two clamping plates; the air supply pump injects external hot steam into the air duct through the pipeline, and the gas is discharged from the air outlet of the air duct and acts on the surface of the tree bark to heat and soften the tree bark, which helps the tree bark to be punched and cut off, reduces the pressure of the cylinder operation, and at the same time, the airflow of the hot steam impacts on the surface of the tree bark to further clean the debris and rotten substances on the surface of the tree bark.

[0013] Preferably, a chopping mechanism is provided below one side of the guide plate; the chopping mechanism includes a feeding roller and a rod body; the end of the feeding roller is rotatably connected to the support plate, and multiple circles of dial rods are evenly arranged on the surface of the feeding roller. The end of the dial rod is arc-shaped and bent outward, and the end of the dial rod extends into a notch opened on the lower surface of the guide plate. One side of the feeding roller is the rod body, and both ends of the rod body are rotatably connected to the support plate. A plurality of crushing knives are arranged on the surface of the rod body, and the distance between adjacent crushing knives is 3-5 mm; the ends of the feeding roller and the rod body are connected to the output end of an external motor. The feeding roller rotates clockwise, and the rod body also rotates clockwise. When strip-shaped bark is pushed out in the guide plate and moves to the end position of the guide plate, the feeding roller rotates and drives the dial rod to rotate. The end of the dial rod rotates into the notch and pulls out the bark at the end of the guide plate. Then, under the restriction of the shape of the end of the dial rod, the bark is rotated to the position of the rod body. The rod body rotates and drives the crushing knives to rotate, and the crushing knives cut and chop the bark, evenly cutting and breaking the strip-shaped bark into particles 3-5 mm long, making the diameter of the chopped particles of the cork bark more uniform. Compared with later crushing, the particle diameter is more uniform.

[0014] Preferably, arc-shaped plates are provided below both ends of the feeding roller. The arc-shaped plates are close to the surface of the end of the feeding roller. The arc-shaped plates are fixedly connected to the support plate, and an inlet inclined surface is provided at the end of the arc-shaped plate; a plurality of notches are evenly opened on the outer ring of the end of the feeding roller, and a wedge-shaped extrusion block is arranged in each notch. The notches at both ends of the feeding roller are communicated with each other. The extrusion blocks at both ends of the feeding roller are arranged opposite to each other, and a connecting rod is arranged between the same pair of extrusion blocks. The end of the connecting rod penetrates into the notch and is fixedly connected to the extrusion block. The extrusion block is slidably connected to the notch through a spring. One side of the extrusion block is fixedly connected to an extrusion rod. The end of the extrusion rod penetrates to the outside of the feeding roller and extends into a through groove opened in the middle position of the dial rod, and the end of the extrusion rod is C-shaped; when the feeding roller rotates, the extrusion block rotates synchronously with the feeding roller. When the extrusion block squeezes the inner concave surface of the arc-shaped plate from the inlet inclined surface of the arc-shaped plate, the extrusion block squeezes the spring and retracts into the notch, and the two opposite extrusion blocks are connected by a connecting rod and retract into the notch synchronously, driving the extrusion rod to retract into the notch. At this time, the gap between the end of the extrusion rod and the end of the dial rod increases. Then, the end of the dial rod is embedded in the notch and pulls out the strip-shaped bark and places it in the arc-shaped concave surface at the end of the dial rod. When the extrusion block separates from the arc-shaped plate, the extrusion block and the extrusion rod reset, and the end of the extrusion rod squeezes the strip-shaped bark, tightly clamping the bark in the gap between the end of the extrusion rod and the end of the dial rod, preventing the bark from falling off the end of the dial rod due to its own gravity when the dial rod drives the bark to rotate, resulting in the crushing knife not touching the bark and causing ineffective cutting and crushing of the strip-shaped bark.

[0015] Preferably, the crushing knives on the surface of the rod body are arranged staggered front and back in the rotation direction; the crushing knives are arranged in an array on the rod body, so that the crushing knives in front of the rotation direction cut and crush different positions on the strip-shaped bark one by one, and each part of the bark is cut and stressed one by one. If the crushing knives are arranged in the same row, it is difficult for the crushing knives in the same row to cut and crush the bark, and it is easy to break the bark into sections, and the cork bark cannot be effectively cut and crushed into particles with a length of 3-5 mm.

[0016] Preferably, the feeding end of the clamping plate is flared; the flared shape increases the feeding space for the cork bark and facilitates the feeding operation of the bark by the staff.

[0017] The beneficial effects of the present invention are as follows: 1. For the novel wall caulking material and its preparation method of the present invention, the addition of the rapid hardening sulphoaluminate cement in the raw materials can offset the inherent shrinkage of the cement mortar, reduce the cracking of the mortar caused by vibration, and also has certain sound insulation and noise reduction capabilities and micro-expansion characteristics, meeting the requirements of different places for the caulking mortar of doors, windows and walls; the raw materials need to be transported to the construction site, otherwise if the mortar is prepared in advance, the cork bark particles have already absorbed water and swelled to saturation, and the effect of collision sealing cannot be achieved. The cork bark is the oak bark. By opening holes in the cork bark, the cork bark particles can adhere to the slurry more stably after being mixed with the mortar. After the holes are opened, the slurry spreads into the holes, and after the slurry dries and solidifies, the cork bark particles are wrapped, thereby increasing the bonding strength between the cork bark particles.

[0018] 2. For the novel wall caulking material and its preparation method of the present invention, the guide roller pushes the bark into the guide plate, and the bark is restricted. Then, through the punching rod, holes are punched, so that the cork bark particles have holes. Even if the strip-shaped bark is broken into granular form, there are still holes or incomplete and defective holes on the surface of the particles. After these holes are mixed with the slurry, the solidified slurry can still wrap the cork bark particles, and can still improve the internal adhesiveness and solidity of the novel wall caulking material.

[0032] Preferably, the new type of wall caulking material further comprises the following raw materials in weight components: Cellulose ether 0.1 - 0.2 parts; Thixotropic agent 0.7 - 0.9 parts; Water repellent 0.8 - 1.5 parts; The cellulose ether is hydroxypropyl methyl cellulose; the thixotropic agent is a composite of bentonite and starch ether at a ratio of 3:1; the water repellent is a composite of silicone powder and rubber powder at a ratio of 1:3.

[0033] Among them, for the preparation of cork bark particles, use the new type of wall caulking material preparation equipment. The new type of wall caulking material preparation equipment is specifically the punching equipment 1, which can punch multiple holes in the cork bark. The punching equipment 1 can refer to Figure 2 - Figure 11 as shown in The punching device 1 specifically includes a support plate 2, a punching mechanism, and a feeding mechanism; the feeding mechanism includes two upper and lower guide rollers 3, the ends of the guide rollers 3 are rotatably connected to the support plate 2, a double-layer guide plate 4 is provided on one side of the guide rollers 3, one edge of the guide plate 4 is close to the gap between the two guide rollers 3, and the punching mechanism is above the guide plate 4. The punching mechanism includes a cross plate 5, a cylinder 6, and a connecting plate 7; the cross plate 5 is fixedly connected to one side of the support plate 2, a plurality of cylinders 6 are fixedly connected to the cross plate 5, the piston rods of the cylinders 6 vertically penetrate the cross plate 5 downward and are fixedly connected to the connecting plate 7, and a punching knife 8 and a plurality of punching rods 9 are fixedly connected to the lower surface of the connecting plate 7; the punching rods 9 are fixedly connected to the connecting plate 7 in a row, the punching rods 9 are close to the guide rollers 3, the punching rods 9 vertically penetrate through the through holes 10 opened on the guide plate 4, one side of the punching rods 9 is the punching knife 8, and the lower edge blade of the punching knife 8 vertically penetrates through the strip-shaped holes 11 opened on the guide plate 4; the ends of the guide rollers 3 are connected to a motor and drive the guide rollers 3 to rotate clockwise. The cork bark is put between the guide rollers 3, and then the guide rollers 3 rub the bark into the guide plate 4. At this time, the cylinder 6 drives the punching rods 9 and the punching knife 8 to move up and down alternately through the connecting plate 7. The punching rods 9 punch holes in the bark, and then push it to continue moving forward. The punching knife 8 cuts the bark into strips. At this time, each strip-shaped bark has holes. Then the strip-shaped bark is broken into particles. Finally, through screening, particles with a diameter of 3-5 mm are selected; the guide rollers 3 push the bark into the guide plate 4, and the bark is restricted. Then, through the punching rods 9, holes are punched. The diameter of the punching rods 9 is 1.5 mm, so that the cork bark particles have holes. Even if the strip-shaped bark is broken into particles, there are still holes or incomplete holes on the surface of the particles. After these holes are mixed with the slurry, the solidified slurry can still wrap the cork bark particles, and can still improve the adhesiveness and solidity inside the new wall caulking material.

[0034] Refer to Figure 2 and Figure 10, on the other side of the guiding roller 3 is a loading mechanism; the loading mechanism includes two upper and lower clamping plates 12. One end of the clamping plate 12 is close to the middle position between the two guiding rollers 3. A plurality of strip-shaped through grooves 28 are evenly formed in the width direction of the two clamping plates 12. The through grooves 28 are rotatably connected to rotating rollers 13. A sprocket is provided at the end of the rotating roller 13. The sprockets on the same side of the clamping plate 12 are connected by a chain drive; when the guiding roller 3 rotates, the cork bark is pushed into the guiding plate 4 through the frictional force between the cork bark and the guiding roller 3. However, this makes the loading action of the cork bark relatively dangerous. Therefore, a loading mechanism is provided. The staff horizontally places the bark at the entrance of the clamping plate 12. The rotating roller 13 rotates through the cooperation of the sprocket and the chain. One of the sprockets is connected to the output end of an external motor. The rotating roller 13 rotates, rubbing the bark into the space between the clamping plates 12, and then rubbing the bark forward through the subsequent rotating rollers 13 and pushing it into the guiding roller 3; the setting of the rotating roller 13 not only rubs the bark forward, reducing the safety risk of loading, but also removes the sundries on the surface of the cork bark. Debris and rotten substances on the surface of the bark are squeezed and crushed when passing through the rotating roller 13. Part of the debris falls through the through grooves 28, and part of the debris is separated during the later screening, reducing the mixing of debris into the mortar and affecting the bonding property and curing strength of the mortar.

[0035] Refer to Figure 2 , the four right-angle positions of the clamping plate 12 are connected together up and down by a tension spring 14, and a screw rod 15 passes through the inner ring of the tension spring 14. The end of the screw rod 15 passes through the four right-angle parts of the clamping plate 12 and is limited on the clamping plate 12 by a nut; the thickness of the cork bark varies. By setting the clamping plate 12 with an adjustable upper and lower spacing, the surface of the rotating roller 13 can effectively press on the surface of the bark. When the bark with a larger thickness is placed between the clamping plates 12, the clamping plates 12 move away from each other and stretch the tension spring 14. When the bark with a smaller thickness is placed between the clamping plates 12, the tension spring 14 pulls and squeezes the bark to ensure that the bark is rubbed forward and the attachments on the surface of the bark are cleaned off.

[0036] Refer to Figure 10 , an air duct 16 is opened inside the clamping plate 12. The air inlet end of the air duct 16 is connected to an external air supply pump through a pipeline, and the air outlet of the air duct 16 is located on the opposite surfaces of the two clamping plates 12; the air supply pump injects external hot steam into the air duct 16 through the pipeline, and the gas is discharged from the air outlet of the air duct 16 and acts on the surface of the bark to heat and soften the bark, which helps the bark to be punched and cut, reduces the pressure of the operation of the cylinder 6, and at the same time, the airflow of the hot steam impacts on the surface of the bark, further cleaning the debris and rotten substances on the surface of the bark.

[0037] Refer to Figure 2 、 Figure 4 and Figure 5, a shredding mechanism is provided below one side of the guide plate 4; the shredding mechanism includes a feeding roller 17 and a rod body 18; the end of the feeding roller 17 is rotatably connected to the support plate 2, and multiple circles of dial rods 19 are evenly arranged on the surface of the feeding roller 17. The end of the dial rod 19 is arc-shaped and bent outward, and the end of the dial rod 19 extends into a notch 20 opened on the lower surface of the guide plate 4. One side of the feeding roller 17 is the rod body 18, and both ends of the rod body 18 are rotatably connected to the support plate 2. A plurality of crushing knives 21 are provided on the surface of the rod body 18, and the distance between adjacent crushing knives 21 is 3-5 mm; the ends of the feeding roller 17 and the rod body 18 are connected to the output end of an external motor. The feeding roller 17 rotates clockwise, and the rod body 18 also rotates clockwise. When strip-shaped bark is pushed out in the guide plate 4 and moves to the end position of the guide plate 4, the feeding roller 17 rotates and drives the dial rod 19 to rotate. The end of the dial rod 19 rotates into the notch 20 and pulls out the bark at the end of the guide plate 4. Then, under the restriction of the shape of the end of the dial rod 19, the bark is rotated and brought to the position of the rod body 18. The rod body 18 rotates and drives the crushing knives 21 to rotate. The crushing knives 21 cut and shred the bark, evenly cutting and breaking the strip-shaped bark into particles 3-5 mm long, making the diameter of the shredded particles of the cork bark more uniform. Compared with later crushing, the particle diameter is more uniform.

[0038] Refer to Figure 5 , Figure 6 , Figure 7 and Figure 8, arc-shaped plates 22 are provided below both ends of the blanking roller 17. The arc-shaped plates 22 are close to the end surface of the blanking roller 17. The arc-shaped plates 22 are fixedly connected to the support plate 2, and an inlet inclined surface 23 is provided at the end of the arc-shaped plate 22; a plurality of notches 24 are evenly opened on the outer ring of the end of the blanking roller 17. A wedge-shaped extrusion block 25 is provided in each notch 24. The notches 24 at both ends of the blanking roller 17 are communicated with each other. The extrusion blocks 25 at both ends of the blanking roller 17 are arranged oppositely, and a connecting rod 26 is provided between the same pair of extrusion blocks 25. The end of the connecting rod 26 penetrates into the notch 24 and is fixedly connected to the extrusion block 25. The extrusion block 25 is slidably connected in the notch 24 through a spring. One side of the extrusion block 25 is fixedly connected with an extrusion rod 27. The end of the extrusion rod 27 penetrates to the outside of the blanking roller 17 and extends into a through groove 28 opened in the middle position of the dial rod 19, and the end of the extrusion rod 27 is in a C shape; when the blanking roller 17 rotates, the extrusion block 25 rotates synchronously with the blanking roller 17. When the extrusion block 25 squeezes the inner concave surface of the arc-shaped plate 22 from the inlet inclined surface 23 of the arc-shaped plate 22, the extrusion block 25 squeezes the spring and retracts into the notch 24, and the two opposite extrusion blocks 25 are connected by the connecting rod 26 and synchronously retract into the notch 24, and drive the extrusion rod 27 to retract into the notch 24. At this time, the gap between the end of the extrusion rod 27 and the end of the dial rod 19 increases. Then, the end of the dial rod 19 is embedded into the notch 20, and the strip-shaped bark is pulled out and placed in the arc-shaped concave surface at the end of the dial rod 19. When the extrusion block 25 disengages from the arc-shaped plate 22, the extrusion block 25 and the extrusion rod 27 are reset. The end of the extrusion rod 27 squeezes the strip-shaped bark, and the bark is tightly clamped in the gap between the end of the extrusion rod 27 and the end of the dial rod 19, preventing the bark from falling off the end position of the dial rod 19 due to its own gravity when the dial rod 19 drives the bark to rotate, resulting in the cutting knife 21 failing to touch the bark and causing ineffective cutting and crushing of the strip-shaped bark.

[0039] Refer to Figure 4 and Figure 9 , on the rotation direction of the cutting knife 21 on the surface of the rod body 18, they are arranged staggered front and back; the cutting knives 21 are arranged in an array on the rod body 18, so that the cutting knives 21 in front of the rotation direction cut and crush different positions on the strip-shaped bark one by one, and each part of the bark is cut and stressed one by one. If the cutting knives 21 are arranged in the same row, it is difficult for the cutting knives 21 in the same row to cut and crush the bark, and it is easy to break the bark into sections, and it fails to effectively cut and crush it into cork bark particles with a length of 3-5 mm.

[0040] Refer to Figure 11 , the feeding end part of the clamping plate 12 is provided with an expanded opening; it is arranged in an expanded opening shape to increase the feeding inlet space of the cork bark and facilitate the feeding operation of the staff on the bark.

[0041] Working principle: Utilizing the characteristics of cork bark particles, which expand when encountering water, have high elasticity, and sound absorption ability, the anti-deformation ability, reinforcement ability, and workability of the mortar are greatly improved. The addition of rapid-hardening sulphoaluminate cement in the raw materials can offset the inherent shrinkage of cement mortar, reduce the cracking caused by vibration to the mortar, and also has certain sound insulation and noise reduction capabilities and micro-expansion characteristics, meeting the requirements of different places for caulking mortar for doors, windows, and walls. The raw materials need to be transported to the construction site. Otherwise, if the mortar is prepared in advance, the cork bark particles will have already absorbed water and expanded to saturation, and will not achieve the effect of impact sealing. Cork bark is oak bark. By opening holes in the cork bark, after the cork bark particles are mixed with the mortar, they can adhere to the slurry more stably. After the holes are opened, the slurry spreads into the holes. After the slurry dries and solidifies, it wraps the cork bark particles, thereby increasing the bonding strength between the cork bark particles. At the same time, oak trees have unique growth characteristics. That is, after the bark is peeled off, the tree can continue to grow. When the bark grows again later, it can be peeled off again and repeated many times. The end of the guiding roller 3 is connected to a motor and drives the guiding roller 3 to rotate clockwise. The cork bark is put into the space between the guiding rollers 3, and then the guiding roller 3 rubs the bark into the guiding plate 4. At this time, the air cylinder 6 drives the punching rod 9 and the punching cutter 8 to move up and down alternately through the connecting plate 7. The punching rod 9 punches holes in the bark, and then it is pushed to move forward continuously. The punching cutter 8 cuts the bark into strips. At this time, each strip-shaped bark has holes. Then the strip-shaped bark is broken and crushed into granular form. Finally, through screening, particles with a diameter of 3 - 5 mm are selected. The guiding roller 3 pushes the bark into the guiding plate 4, and the bark is restricted. Then, through the punching rod 9, holes are punched, so that the cork bark particles have holes. Even if the strip-shaped bark is broken into granular form, there are still holes or incomplete and damaged holes on the surface of the particles. After these holes are mixed with the slurry, the solidified slurry can still wrap the cork bark particles, and can still improve the internal adhesiveness and solidity of this new type of wall caulking material. When the guiding roller 3 rotates, it pushes the cork bark into the guiding plate 4 through the frictional force with the cork bark. This makes the feeding action of the cork bark relatively dangerous. Therefore, a feeding mechanism is set up. The staff horizontally place the bark at the entrance of the clamping plate 12. The rotating roller 13 rotates through the cooperation of a sprocket and a chain. One of the sprockets is connected to the output end of an external motor. The rotating roller 13 rotates, rubs the bark into the space between the clamping plates 12, and then rubs the bark forward through the subsequent rotating roller 13 and pushes it into the guiding roller 3. The setting of the rotating roller 13 not only rubs the bark forward and reduces the safety risk of feeding, but also removes the sundries on the surface of the cork bark. Debris and rotten substances on the surface of the bark are squeezed and crushed when passing through the rotating roller 13. Part of the debris falls through the through groove 28, and part of the debris is separated during the subsequent screening, reducing the debris from mixing into the mortar and affecting the adhesiveness and curing strength of the mortar. The thickness of the cork bark varies. By setting the splints 12 with adjustable upper and lower spacing, the surface of the rotating roller 13 can effectively press on the surface of the bark. When the bark with a larger thickness is placed between the splints 12, the splints 12 move away from each other and stretch the tension spring 14. When the bark with a smaller thickness is placed between the splints 12, the tension spring 14 pulls and squeezes the bark to ensure that the bark is rubbed and moved forward and the attachments on the bark surface are cleaned off; The air supply pump injects external hot steam into the air duct 16 through a pipeline. The gas discharges from the air outlet of the air duct 16 and acts on the surface of the bark to heat and soften the bark, which helps the bark to be punched and cut off, reduces the operating pressure of the cylinder 6. At the same time, the airflow of the hot steam impacts on the bark surface, which further cleans the debris and rotten matter on the bark surface; The end of the feeding roller 17 and the rod body 18 are connected to the output end of an external motor. The feeding roller 17 rotates clockwise, and the rod body 18 also rotates clockwise. The strip-shaped bark is pushed out in the guide plate 4. When it moves to the end position of the guide plate 4, the feeding roller 17 rotates and drives the dial rod 19 to rotate. The end of the dial rod 19 rotates into the notch 20 and pulls out the bark at the end of the guide plate 4. Then, under the limitation of the shape of the end of the dial rod 19, the bark is rotated and brought to the position of the rod body 18. The rod body 18 rotates and drives the crushing knife 21 to rotate. The crushing knife 21 cuts and shreds the bark, evenly cutting and breaking the strip-shaped bark into particles 3 - 5 mm long, making the diameter of the shredded cork bark particles more uniform. Compared with later crushing, the particle diameter is more uniform; The feeding roller 17 rotates, and the extrusion block 25 rotates synchronously with the feeding roller 17. When the extrusion block 25 squeezes the concave surface of the arc plate 22 from the inlet inclined surface 23 of the arc plate 22, the extrusion block 25 squeezes the spring and retracts into the notch 24. And the two opposite extrusion blocks 25 are connected by a connecting rod 26 and synchronously retract into the notch 24, driving the extrusion rod 27 to retract into the notch 24. At this time, the gap between the end of the extrusion rod 27 and the end of the dial rod 19 increases. Then, the end of the dial rod 19 is embedded in the notch 20 and pulls out the strip-shaped bark and places it in the arc-shaped concave surface at the end of the dial rod 19. When the extrusion block 25 disengages from the arc plate 22, the extrusion block 25 and the extrusion rod 27 reset. The end of the extrusion rod 27 squeezes the strip-shaped bark, tightly clamping the bark in the gap between the end of the extrusion rod 27 and the end of the dial rod 19, preventing the bark from detaching from the end position of the dial rod 19 due to its own gravity when the dial rod 19 drives the bark to rotate, resulting in the ineffective cutting and crushing of the strip-shaped bark by the crushing knife 21; The crushing knives 21 are arranged in an array on the rod body 18, so that the crushing knives 21 in front of the rotation direction cut and crush different positions on the strip-shaped bark one by one, and each part of the bark is cut and stressed one by one. If the crushing knives 21 are arranged in the same row, it is difficult for the crushing knives 21 in the same row to cut and crush the bark, and it is easy to break the bark into sections, and the cork bark cannot be effectively cut and crushed into particles with a length of 3-5 mm.
