Description

Technical Field

[0001] The invention relates to the technical field of rubber extruders, and in particular to a digitally controlled integrated extruder for producing long-lasting heat-insulating and weather-resistant rubber strips for doors and windows. Background Art

[0002] The rubber strips installed on doors and windows are used to seal between the openable window sashes and window frames. The rubber strips are generally made of rubber materials and installed at the contact point between the window sashes and window frames. When the window sashes are closed, the rubber strips are squeezed to fill the gap between the window sashes and window frames to achieve sealing, thereby achieving long-term indoor thermal insulation. The rubber strips are usually produced by rubber extruders. The raw materials for producing the rubber strips are usually thermoplastic elastomer particles. The rubber strips produced from thermoplastic elastomer particles have good aging resistance and can resist corrosion from chemical substances such as acids and alkalis. In environments with salt fog near factories or at the seaside, the rubber strips will not be easily corroded and have good weather resistance. Performance: When using a rubber extruder to generate rubber strips, thermoplastic elastomer particles are added to a feed hopper, and fall from the feed hopper into the barrel of the rubber extruder. The spiral conveying rod in the barrel rotates to convey the thermoplastic elastomer particles. During the conveying process, the thermoplastic elastomer particles are melted by heat and then extruded from the extrusion die. After cooling, rubber strips can be formed. The rubber extruder adopts a CNC temperature control system, which monitors the temperature of the barrel, screw, and die in real time through high-precision temperature sensors, and feeds back the data to the CNC unit. The CNC unit accurately adjusts the heating power according to the preset temperature curve to ensure the production quality of the rubber strips.

[0003] When a common CNC integrated extruder for the production of long-term thermal insulation and weather-resistant rubber strips for doors and windows is in use, thermoplastic elastomer particles are added into a feed hopper, and the thermoplastic elastomer particles fall into the barrel of the rubber extruder along the inner wall of the feed hopper. However, the thermoplastic elastomer particles are prone to oil production due to their own production formula and the high ambient temperature in summer. The thermoplastic elastomer particles after oil production are prone to agglomeration. After the agglomerated thermoplastic elastomer particles enter the barrel of the rubber extruder, the agglomerated thermoplastic elastomer particles are difficult to be evenly heated and melted, resulting in incompletely melted particles inside the rubber strip, thereby affecting the quality of the rubber strip. Therefore, the present application provides a CNC integrated extruder for the production of long-term thermal insulation and weather-resistant rubber strips for doors and windows to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a CNC integrated extruder for the production of long-lasting thermal insulation and weather-resistant rubber strips for doors and windows to solve the problem that after the agglomerated thermoplastic elastomer particles enter the barrel of the rubber extruder, the agglomerated thermoplastic elastomer particles are difficult to be evenly heated and melted, which will cause incompletely melted particles to appear inside the rubber strip, thus affecting the quality of the rubber strip.

[0014] Preferably, the inner wall of the feed hopper is provided with a plurality of recessed portions, and oil-absorbing cloths are installed in the recessed portions.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, through the arrangement of the motor, the hollow lever and the cooling mechanism, the motor drives the hollow lever to rotate, so as to disperse the agglomerated granular raw materials in the feed hopper, and ensure that the granular raw materials enter the barrel of the extruder body in a uniform and loose state, so that the melting of the granular raw materials is more uniform, and the appearance of incompletely melted particles inside the rubber strip is prevented, so as to ensure the quality of the rubber strip.

[0017] By setting the long groove and the shifting block, the friction between the hollow shifting rod and the granular raw material is increased by utilizing the long groove and the shifting block, and the ability of the hollow shifting rod to disperse the granular raw material is further improved, thereby reducing the possibility of residual agglomerated granular raw materials.

[0018] Through the arrangement of the lever, the extrusion block and the rod, the hollow lever drives the lever to rotate along the inner wall of the round box during the process of rotating with the round tube as the axis, and the cooperation of the lever and the multiple extrusion blocks in the round box drives the rod to continuously perform telescopic movements. When the rod is extended from the accommodating groove, the area of ​​the hollow lever stirring the granular raw material can be increased, and the ability to disperse the granular raw material can be further improved. At the same time, the length of the long part on the lever is twice that of the short part, which can increase the extension distance of the rod, and further increase the area of ​​the hollow lever stirring the granular raw material, thereby further improving the ability of the hollow lever to disperse the granular raw material, making the dispersion of the granular raw material more sufficient and thorough.

[0019] Through the setting of the oil-absorbing cloth, when the granular raw materials are stirred by the spreading mechanism and pass through the position of the oil-absorbing cloth, the oil-absorbing cloth can wipe and clean the grease seeping from the surface of the granular raw materials, thereby effectively preventing the granular raw materials from agglomerating in the feed hopper, further ensuring the looseness and fluidity of the granular raw materials, and laying a stable and reliable foundation for the subsequent extrusion process.

When working, the motor 25 drives the hollow lever 6 on the round tube 5 to rotate in the feed hopper 2 through the vertical shaft 4 to disperse the agglomerated granular raw materials. The arrangement of the lever 24 at the bottom of the vertical shaft 4 can further stir and disperse the granular raw materials near the bottom of the feed hopper 2, prevent the granular raw materials from accumulating or agglomerating at the bottom of the feed hopper 2, ensure that the granular raw materials in the entire feed hopper 2 are in a good flow and loose state, and improve the uniformity and stability of the granular raw materials entering the barrel; The cooling mechanism 33 is used to cool the granular raw material in the feed hopper 2 during the rotation of the vertical shaft 4 and the hollow lever 6. The cooling mechanism 33 can effectively solve the impact of the high ambient temperature in summer or the heat generated by the operation of the extruder body 1 on the granular raw material. By cooling the granular raw material, the temperature of the granular raw material is reduced, and the granular raw material is prevented from producing oil and agglomeration due to overheating, so that the granular raw material can be melted more stably after entering the barrel of the extruder body 1.

[0027] like Figure 5As shown, in this embodiment, the cooling mechanism 33 includes a water inlet annular groove 36 and a water outlet annular groove 37 provided in the support seat 27, and a water inlet component 34 and a water outlet component 35 are fixed on both sides of the support seat 27, the water inlet component 34 is connected to the water inlet annular groove 36, and the water outlet component 35 is connected to the water outlet annular groove 37, and a water inlet channel 38 and two groups of return water channels 40 are respectively provided inside the vertical shaft 4, a cooling cavity 39 is provided in the protrusion 23, and a sleeve 46 is fixed on the top of the inner wall of the cooling cavity 39, The water inlet channel 38 is used for the communication between the water inlet annular groove 36 and the cooling chamber 39, and the water return channel 40 is used for the communication between the cooling chamber 39 and the water outlet annular groove 37, and the water return channel 40 is communicated with the hollow lever 6 through the round tube 5. Three sealing rings are installed in the support seat 27. The sealing rings located at the top and bottom are used to prevent the water at the water inlet annular groove 36 and the water outlet annular groove 37 from flowing out from between the support seat 27 and the vertical shaft 4, and the sealing ring located in the middle is used to prevent the water inlet annular groove 36 and the water outlet annular groove 37 from communicating with each other; During the rotation of the hollow lever 6, the water inlet component 34 delivers water into the cooling chamber 39 through the water inlet channel 38 to cool the hot granular raw materials at the protrusion 23. The water flows into each row of the hollow lever 6 from bottom to top through the return water channel 40, and is finally discharged from the water outlet component 35. During the rotation of the hollow lever 6, the water flowing inside the hollow lever 6 is used to cool the granular raw materials in contact. The water inlet component 34 is connected to the water outlet of the chiller, and the water outlet component 35 is connected to the water inlet of the chiller. The water flow is cooled by the chiller and delivered to the water inlet component 34. Then, the water flows into the cooling chamber 39 through the water inlet channel 38, so as to cool the granular raw materials at the protrusion 23 which are affected by the heat inside the barrel of the extruder body 1 and are in a high temperature state. After that, the water flows into each row of hollow levers 6 in turn through the return water channel 40, and is finally discharged from the water outlet component 35. During the rotation of the hollow lever 6, the water flowing inside the hollow lever 6 is used to cool the contacted granular raw materials, thereby reducing the influence of the heat generated by the high ambient temperature in summer or the operation of the extruder body 1 on the granular raw materials, and preventing the granular raw materials from further agglomerating due to overheating.

[0028] like Figure 5As shown, in this embodiment, the return water channel 40 includes a return water channel 1 41, a return water channel 2 42 and a return water channel 3 43 which are opened in the vertical axis 4. The return water channel 1 41 is used for connecting the cooling chamber 39 with the circular tube 5 located below. A return water hole 1 44 is opened on the side of the raised portion 10 located below, and a return water hole 2 45 is opened on the side of the raised portion 10 located above. The return water hole 1 44 is used for connecting the hollow lever 6 located below with the return water channel 2 42. The return water channel 2 42 is used for connecting the return water hole 1 44 with the circular tube 5 located above. The return water hole 2 45 is used for connecting the hollow lever 6 located above with the return water channel 3 43. The return water channel 3 4 The water is used to connect the second water return hole 45 with the water outlet annular groove 37. The first water return channel 41 first guides the water in the cooling chamber 39 to the lower circular tube 5, enters the lower hollow lever 6 through the lower circular tube 5, then enters the second water return channel 42 through the first water return hole 44, enters the upper circular tube 5 through the second water return channel 42, then enters the upper hollow lever 6 through the upper circular tube 5, and then passes through the second water return hole 45, the third water return channel 43 and the water outlet annular groove 37 in sequence, and finally is discharged from the water outlet component 35, so that the hollow lever 6 from bottom to top can be effectively cooled, and the cooling of the granular raw materials is more uniform.

[0029] like Figure 2-Figure 4 As shown, in this embodiment, two circular rings 30 are fixed on the inner wall of the feed hopper 2, a circular disc 28 is fixed to the end of the hollow lever 6 away from the vertical axis 4 through the circular axis, a blocking cover 31 is fixed to the bottom of the circular ring 30, and the blocking cover 31 is located between the hollow lever 6 and the circular disc 28. A plurality of grooves 29 are provided on the circumferential surface of the circular disc 28, and a plurality of protrusions 32 are fixed to the bottom of the circular ring 30. When the hollow lever 6 rotates with the vertical axis 4 as the axis, the circular disc 28 is driven to rotate along the bottom of the circular ring 30. When the circular disc 28 rotates along the bottom of the circular ring 30, the plurality of protrusions 32 are sequentially inserted into the corresponding grooves 29, so that the hollow lever 6 rotates with the circular tube 5 as the axis. When the hollow lever 6 rotates with the vertical axis 4 as the axis The disc 28 at its end will continue to rotate along the bottom of the ring 30. During the rotation of the disc 28 along the bottom of the ring 30, several protrusions 32 at the bottom of the ring 30 are inserted into the corresponding grooves 29 in sequence, so that the disc 28 drives the hollow lever 6 to rotate with the circular tube 5 as the axis, thereby improving the stirring ability of the granular raw materials, thereby improving the ability to disperse the granular raw materials. The depth of the groove 29 is smaller than the size of the granular raw materials, which can prevent the disc 28 from bringing the granular raw materials into the space between the disc 28 and the ring 30 during the rotation process, and the baffle 31 can effectively prevent the granular raw materials from entering the space between the disc 28 and the ring 30, thereby ensuring that the disc 28 rotates smoothly along the bottom of the ring 30.

[0030] like Figure 2As shown, in the present embodiment, the top of the ring 30 is a downwardly inclined slope. The design of the slope can guide the granular raw material to flow to the central area of ​​the feed hopper 2, thereby avoiding the accumulation of the granular raw material near the inner wall of the feed hopper 2, and making the granular raw material more concentrated within the action range of the hollow lever 6, thereby improving the processing capacity of the hollow lever 6 for the granular raw material. At the same time, the existence of the slope can reduce the residue of the granular raw material on the top of the ring 30.

[0031] like Figure 6 As shown, in this embodiment, the hollow lever 6 is in the shape of an equilateral triangle, and a plurality of long grooves 7 are provided on the side of the hollow lever 6. The long grooves 7 are in the shape of a right triangle, and the long grooves 7 are the same length as the hollow lever 6. Due to the shape of the equilateral triangle, when the hollow lever 6 rotates and revolves, its three sides can move and stir the granular raw materials from different directions, so that the granular raw materials around the hollow lever 6 are irregularly rolled, which helps to break the adhesion between the granular raw materials and further improves the ability to disperse the granular raw materials. The long grooves 7 are used to increase the friction between the hollow lever 6 and the granular raw materials. It can better grasp the agglomerated granular raw materials, and generate greater pulling and torsional forces on the agglomerates during the rotation process, and at the same time can more effectively drive the granular raw materials to roll. During the rolling process, the particles inside the agglomerates will constantly change their relative positions, further destroying the integrity of the agglomerates and thus improving the ability to disperse the agglomerated granular raw materials. The long groove 7 is a right-angled triangle. During the rotation of the hollow lever 6, when the agglomerated granular raw materials contact the connection between the short right-angled side in the long groove 7 and the upper hypotenuse of the hollow lever 6, the impact force of the hollow lever 6 on the agglomerated granular raw materials is increased through the connection, which helps to disperse the agglomerated granular raw materials.

[0032] like Figure 6 As shown, in this embodiment, a plurality of shifting blocks 8 are fixed to the side of the hollow shifting rod 6, and the shifting block 8 is located between two adjacent long grooves 7. A V-shaped surface 9 is provided on the side of the shifting block 8. Through the design of the shifting block 8, the hollow shifting rod 6 can generate greater impact force and friction force on the granular raw material when rotating, thereby improving the dispersion effect on the agglomerated granular raw material. Through the design of the V-shaped surface 9, when the sharp corner of the V-shaped surface 9 on the shifting block 8 contacts the agglomerated granular raw material, the pressure of the shifting block 8 on the agglomerated granular raw material is increased by reducing the contact area between the shifting block 8 and the granular raw material, thereby improving the ability of the shifting block 8 to disperse the agglomerated granular raw material.

[0033] like Figure 7-Figure 9As shown, in this embodiment, the outer wall of the round tube 5 is sleeved with a round box 21, and a plurality of extrusion blocks 22 are fixed to the inner wall of the round box 21. The inner wall of the hollow lever 6 is respectively fixed with a rotating shaft 11 and a spring 17. The end of the rotating shaft 11 is rotatably connected to a lever 12, and the end of the spring 17 is fixed with a movable disk 16. One end of the lever 12 is rotatably connected to the inner wall of the round box 21, and the other end of the lever 12 is in contact with the side of the movable disk 16. A connecting column 18 is fixed to the side of the movable disk 16 away from the lever 12. The connecting column 18 is located inside the spring 17, and a receiving groove 20 is provided at the corner of the side of the hollow lever 6. The number of receiving grooves 20 on the same hollow lever 6 is three. A bar 19 is slidably connected in the receiving groove 20. The side of the bar 19 is fixedly connected to the end of the connecting column 18 away from the movable disk 16. During the self-rotation of the hollow lever 6 with the round tube 5 as the axis, the hollow lever 6 drives the lever 12 to rotate along the inner wall of the round box 21 through the rotating shaft 11. A plurality of extrusion blocks 22 on the inner wall of the round box 21 The end of the lever 12 is continuously squeezed. When the squeezing block 22 squeezes the end of the lever 12, the lever 12 is rotated around the rotating shaft 11, so that the end of the lever 12 away from the round box 21 squeezes the movable disk 16, so that the movable disk 16 squeezes the spring 17 and drives the bar 19 at the end of the connecting column 18 to extend from the receiving groove 20. When the bar 19 extends from the receiving groove 20, the area of ​​the hollow lever 6 stirring the granular raw material can be increased, so that the granular raw material can be dispersed more fully and thoroughly. When the lever 12 is separated from the squeezing block 22, the movable disk 16 drives the bar 19 at the end of the connecting column 18 to contract under the elastic force of the spring 17. At the same time, the movable disk 16 moves toward the direction close to the circular tube 5 under the elastic force of the spring 17 and squeezes the end of the lever 12, so that the lever 12 rotates in the opposite direction around the rotating shaft 11 and fits against the inner wall of the round box 21. The continuous squeezing of a plurality of squeezing blocks 22 causes the bar 19 to continuously perform telescopic movement, thereby improving the ability of the hollow lever 6 to disperse the granular raw material.

[0034] like Fig.10As shown, in this embodiment, the lever 12 includes a short portion 13, a rotating portion 14 and a long portion 15 connected in sequence, the end of the short portion 13 away from the rotating portion 14 is rotatably connected to the inner wall of the round box 21, the rotating portion 14 is sleeved on the end of the rotating shaft 11, and the end of the long portion 15 away from the rotating portion 14 is in contact with the side of the movable disk 16 away from the connecting column 18, the length of the long portion 15 is twice the length of the short portion 13, and the end of the long portion 15 away from the rotating portion 14 is spherical, and the length of the long portion 15 is twice the length of the short portion 13. At the same rotation angle, the long portion 15 can push The movable disk 16 produces a larger displacement, thereby achieving a larger extension distance of the bar 19, further enhancing the ability of the hollow lever 6 to disperse the granular raw materials. The bar 19 will not separate from the inner wall of the accommodating groove 20 when extended to the farthest distance, thereby preventing the granular raw materials from entering between the accommodating groove 20 and the bar 19 and affecting the extension and retraction of the bar 19. The spherical end of the long portion 15 reduces the contact area with the movable disk 16, preventing the spherical end of the long portion 15 from getting stuck when moving sideways on the movable disk 16, thereby making the rotation of the lever 12 smoother.

[0035] like Figure 2 As shown, in the present embodiment, a plurality of recessed portions 48 are provided on the inner wall of the feed hopper 2, and an oil-absorbing cloth 47 is installed in the recessed portion 48. The oil-absorbing cloth 47 can be installed in the recessed portion 48 by glue or bolts. When the granular raw material is stirred by the dispersing mechanism 3, it will rotate in the feed hopper 2. When the granular raw material passes through the position of the oil-absorbing cloth 47 installed in the recessed portion 48 on the inner wall of the feed hopper 2, the oil-absorbing cloth 47 can wipe and clean the grease seeping out from the surface of the granular raw material, thereby effectively preventing the granular raw material from agglomerating in the feed hopper 2, and further ensuring the looseness and fluidity of the granular raw material.

[0036] Working principle: When working, add the granular raw materials into the feed hopper 2. When the granular raw materials enter the feed hopper 2, start the motor 25, the motor 25 drives the round tube 5 on the vertical axis 4 to rotate in the feed hopper 2, and the round tube 5 drives the hollow lever 6 to rotate in the feed hopper 2 to disperse the agglomerated granular raw materials in the feed hopper 2; During the rotation of the hollow lever 6 with the vertical axis 4 as the axis, the disc 28 at the end thereof will continue to rotate along the bottom of the ring 30. During the rotation of the disc 28 along the bottom of the ring 30, the plurality of protrusions 32 at the bottom of the ring 30 are sequentially inserted into the corresponding grooves 29, so that the disc 28 drives the hollow lever 6 to rotate with the circular tube 5 as the axis. The hollow lever 6 is an equilateral triangle. The shape of the equilateral triangle is combined with rotation and revolution to stir the granular raw materials from multiple angles and directions, which greatly improves the stirring ability of the granular raw materials and effectively improves the ability to disperse the agglomerated granular raw materials. At the same time, the side of the hollow lever 6 is provided with a long groove 7 and a fixed lever block 8 to increase the friction between the lever and the granular raw material, further enhancing the ability to disperse the granular raw material and reducing the possibility of the residue of the agglomerated granular raw material. At the same time, when the sharp corner of the V-shaped surface 9 on the lever block 8 contacts the agglomerated granular raw material, the pressure exerted by the lever block 8 on the agglomerated granular raw material is increased by reducing the contact area between the lever block 8 and the granular raw material, thereby improving the ability of the lever block 8 to disperse the agglomerated granular raw material. In the process of the hollow lever 6 rotating with the round tube 5 as the axis, the hollow lever 6 drives the lever 12 to rotate along the inner wall of the round box 21 through the rotating shaft 11, and the multiple squeezing blocks 22 on the inner wall of the round box 21 continuously squeeze the end of the lever 12. When the squeezing block 22 squeezes the end of the lever 12, the lever 12 rotates with the rotating shaft 11 as the axis, so that the end of the lever 12 away from the round box 21 squeezes the movable disk 16, so that the movable disk 16 moves away from the round tube 5 and squeezes the spring 17. The movable disk 16 squeezes the spring 17 and drives the bar 19 at the end of the connecting column 18 to extend from the receiving groove 20. When the bar 19 extends from the receiving groove 20, the area of ​​the hollow lever 6 stirring the granular raw material can be increased, and the length of the long part 15 on the lever 12 is equal to the short part 1 3, the extension distance of the bar 19 can be increased, and the area of ​​the hollow lever 6 stirring the granular raw material can be further expanded, thereby further improving the ability of the hollow lever 6 to disperse the granular raw material, so that the granular raw material can be dispersed more fully and thoroughly. When the lever 12 is separated from the extrusion block 22, the movable disk 16 drives the bar 19 at the end of the connecting column 18 to contract under the elastic force of the spring 17. At the same time, the movable disk 16 moves toward the direction close to the circular tube 5 under the elastic force of the spring 17 and squeezes the end of the lever 12, so that the lever 12 rotates in the opposite direction with the rotating shaft 11 as the axis and fits with the inner wall of the round box 21. The bar 19 is continuously extruded by a plurality of extrusion blocks 22 to continuously perform telescopic movement, thereby improving the ability of the hollow lever 6 to disperse the granular raw material.

[0037] During the rotation of the hollow lever 6, the cooling mechanism 33 is started synchronously, and the water inlet component 34 sends water into the water inlet ring groove 36 in the support seat 27. The water enters the cooling cavity 39 in the protrusion 23 through the water inlet channel 38 inside the vertical shaft 4, and cools the granular raw materials at the protrusion 23 that are affected by the heat inside the barrel on the extruder body 1 and are in a high temperature state. After that, the water flows into each row of the hollow lever 6 in turn through the return water channel 40, and is finally discharged from the water outlet component 35. During the rotation of the hollow lever 6, the water flowing inside the hollow lever 6 is used to cool the contacted granular raw materials, thereby reducing the influence of the heat generated by the high ambient temperature in summer or the operation of the extruder body 1 on the granular raw materials, and preventing the granular raw materials from further agglomerating due to overheating; During the whole process, when the granular raw materials are stirred, they will rotate in the feed hopper 2. When the granular raw materials pass through the position of the oil-absorbing cloth 47 installed in the recessed portion 48 of the inner wall of the feed hopper 2, the oil-absorbing cloth 47 can wipe and clean the grease seeping from the surface of the granular raw materials, thereby effectively preventing the granular raw materials from agglomerating in the feed hopper 2, and further ensuring the looseness and fluidity of the granular raw materials. After the granular raw materials are dispersed and cooled in the feed hopper 2, they enter the barrel of the extruder body 1, are melted by heat in the barrel, and are extruded by the screw conveyor rod before being discharged from the extrusion die. After cooling, they can form rubber strips for doors and windows.
