Description

Technical Field

[0001] The invention relates to the technical field of EPS foam board production lines, in particular to an EPS foam board production line. Background Art

[0002] EPS foam board is also called polystyrene foam board. EPS board is a white object made of expandable polystyrene beads containing volatile liquid foaming agent, which is pre-expanded by heating and then heated in a mold.

[0003] The production of EPS foam board is carried out through foaming in pre-expander, curing in fluidized bed, aging and molding. When foaming in the pre-expander, the raw material is fed into the pre-expander through the feeding screw from the feeding port, and the raw material is foamed by the hot steam introduced inside. At the same time, the rotation of the stirring device inside the pre-expander enables the raw material to fully contact the hot steam. In this process, the diameter of the raw material increases, and after foaming, it is pushed to the upper end of the pre-expander and the inside by the subsequent raw materials, and enters the fluidized bed from the discharge port for curing.

[0004] During use of the prior art, when the raw materials enter the pre-expander from the feed port, the raw materials fall from the feed hopper position to contact the screw, and then the motor drives the screw to rotate and continuously inject the raw materials into the pre-expander. Since the raw materials are granular and have an uneven surface, the particles squeeze each other and accumulate at the feed port, which will cause the feed port to be blocked, resulting in insufficient foaming material in the pre-expander barrel, and it is difficult for the fully foamed foam particles to accumulate and move upward, and thus they cannot be discharged. The foam particles stay in the pre-expander barrel for too long, causing the foam particles to shrink, which in turn leads to a decrease in the overall working efficiency of the pre-expander.

[0005] Therefore, a EPS foam board production line is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present invention provides an EPS foam board production line, which solves the problem that raw materials are accumulated at the feed inlet of the existing pre-expander, causing the feed inlet to be blocked, thereby causing the foam particles foamed in the pre-expander to be difficult to discharge for a long time, the foam particles are exposed to too much hot steam, causing the foam particles to shrink, and the overall working efficiency of the pre-expander to decrease.

[0030] The technical solution in the embodiment of the present invention is to solve the above technical problems, and the overall idea is as follows: the raw materials at the feed inlet of the pre-expander are accumulated, causing the feed inlet to be blocked. The electric screw at the feed inlet can be used for transmission, and the first bevel gear can be used to change the rotation direction. A rotating plate is set at the feed inlet. As the feed screw rotates, the rotating plate at the feed inlet is driven by a belt to rotate, and the raw materials at the feed inlet are pressed down, thereby destroying the static balance of the raw material accumulation, so that the raw materials can continuously enter the pre-expander barrel with the transmission of the feed screw.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 8 The present invention provides an EPS foam board production line, comprising:

[0033] Bracket 1;

[0034] The pre-making barrel 2 is fixedly connected to one end of the upper surface of the bracket 1;

[0035] The pre-furling assembly 3 penetrates the center of the lower surface of the pre-furling barrel 2 and is fixedly connected to the lower end of the pre-furling barrel 2;

[0036] The control component 4 is fixedly connected to the upper surface of the bracket 1 near the pre-making barrel 2;

[0037] A feeding mechanism 5 is fixedly connected to the lower end of the outer surface of the pre-foaming barrel 2, and the feeding mechanism 5 destroys the blockage of the raw materials at the feed port during the pre-foaming operation.

[0038] In the prior art, when the raw material enters the pre-expander through the feed port, the raw material falls from the feed hopper to contact the screw, and then the motor drives the screw to rotate to continuously inject the raw material into the pre-expander. Since the raw material is in granular form and has an uneven surface, the particles squeeze each other and accumulate at the feed port, which will cause the feed port to be blocked, resulting in insufficient foaming material in the pre-expander barrel 2. It is difficult for the fully foamed foam particles to accumulate and move upward, and thus they cannot be discharged. The foam particles stay in the pre-expander barrel 2 for too long, causing the foam particles to shrink, which in turn leads to a decrease in the overall working efficiency of the pre-expander. The present invention provides a feeding mechanism 5, and the raw material enters the pre-expander barrel 2 through the feeding mechanism 5. The problem of raw material blockage is avoided in the process, so that the raw material can continuously enter the pre-expander barrel 2, and then the pre-expander assembly 3. Hot steam is introduced into the pre-frothing barrel 2, and the raw materials in the pre-frothing barrel 2 are stirred to ensure sufficient contact between the raw materials and the hot steam. The foamed raw materials become foam particles. As the stirring progresses, the unfoamed raw materials have a small diameter and fall to the lower layer of the accumulated raw materials. The foamed raw materials have a larger diameter and are pushed by the airflow to float on the uppermost layer of the accumulated raw materials. As the foaming of the raw materials proceeds, the accumulation of raw materials increases, and the foam particles in the uppermost layer that have been foamed are discharged from the pre-frothing barrel 2 to avoid the mutual squeezing of the raw material particles and the accumulation at the feed port, which leads to the blockage of the feed port. It is also avoided that due to insufficient foaming material in the pre-frothing barrel 2, the fully foamed foam particles are difficult to accumulate and move upward, and thus cannot be discharged. The foam particles stay in the pre-frothing barrel 2 for too long, causing the foam particles to shrink, resulting in a decrease in the overall working efficiency of the pre-frothing machine.

[0039] As an embodiment of the present invention, Figures 1 to 4 As shown, the feeding mechanism 5 includes a feeding channel 51 fixedly connected to the lower end of the outer surface of the pre-expanding barrel 2, a first motor 52 is fixedly connected to the lower surface of the inner part of the feeding channel 51, a feeding screw 54 is fixedly connected to one end of the output shaft of the first motor 52, one end of the feeding screw 54 passes through the pre-expanding barrel 2 and extends to the inside of the pre-expanding barrel 2, a second bevel gear 541 is fixedly connected to the outer surface of the outer surface of the feeding screw 54 close to the first motor 52. The outer surface of the second bevel gear 541 is meshingly connected with the first bevel gear 53, a first rotating shaft 55 is fixed to one end of the first bevel gear 53, a transmission belt 56 is wound around the outer surface of the first rotating shaft 55, and the end of the transmission belt 56 away from the first bevel gear 53 is wound around the first rotating shaft 55 in the same way, the first rotating shaft 55 away from the end of the first bevel gear 53 is rotatably connected to the feeding channel 51, and the outer surface of the first rotating shaft 55 away from the end of the first bevel gear 53 is annularly fixedly connected with evenly distributed rotating plates 57.

[0040] In view of the problems existing in the prior art, the present invention provides a feeding mechanism 5. First, the raw material is poured into the feeding channel 51. At this time, the first motor 52 is started. When the first motor 52 rotates, the output shaft rotates to drive the feeding screw 54 to rotate. The feeding screw 54 transports the raw material into the pre-fermentation barrel 2. At the same time, the rotation of the feeding screw 54 drives the second bevel gear 541 to rotate, and then the second bevel gear 541 rotates the first bevel gear 53 through meshing motion. The rotation of the first bevel gear 53 causes the first bevel gear 53 to rotate. The first rotating shaft 55 fixedly connected rotates, and then the transmission belt 56 rotates through the rotation of the first rotating shaft 55, and then the first rotating shaft 55 at the other end rotates, and the rotation of the first rotating shaft 55 at this end rotates the rotary plate 57. During the rotation of the rotary plate 57, contact will occur, and then the two rotary plates 57 are pressed, and the raw materials at the lower end of the feeding channel 51 are pressed into the feeding screw 54, so that the raw materials can smoothly enter the pre-expanding barrel 2. At this time, the pre-expanding component 3 passes hot steam into the pre-expanding barrel 2 and presses the pre-expanding barrel 2. The raw materials at the bottom are stirred to make full contact between the raw materials and the hot steam, and the foamed raw materials become foam particles. As the stirring proceeds, the unfoamed raw materials with a small diameter fall to the lower layer of the accumulated raw materials, and the foamed raw materials have a larger diameter and are pushed by the airflow to float on the uppermost layer of the accumulated raw materials. As the raw materials foam, the accumulation of raw materials increases, and the foam particles on the uppermost layer are discharged from the pre-expansion barrel 2 from the outlet at the upper end of the pre-expansion barrel 2. This method is achieved by linking the rotation of the rotary plate 57 with the rotation of the feeding screw 54. At the same time, the rotary plate 57 presses the raw materials in the feed channel 51, and smoothly presses the raw materials into the feed screw 54, so as to ensure the continuity of the feeding, avoid the mutual squeezing of the raw material particles and the accumulation at the feed port, which leads to the blockage of the feed port. At the same time, it also avoids the problem that due to insufficient foaming material in the pre-expansion barrel 2, the fully foamed foam particles are difficult to accumulate and move upward, and then cannot be discharged, and the foam particles stay in the pre-expansion barrel 2 for too long, causing the foam particles to shrink, resulting in a decrease in the overall working efficiency of the pre-expansion machine.

[0041] As an embodiment of the present invention, Figure 3 , Figure 5 As shown, the rotating plate 57 is fixedly connected to one end away from the first rotating shaft 55 with a buffer block 58, and the buffer block 58 is a component made of rubber material. The outer surface of the first rotating shaft 55 is annularly fixedly connected with evenly distributed trapezoidal blocks 50, and the trapezoidal blocks 50 are meshed and connected with the transmission belt 56.

[0042] When the first rotating shaft 55 rotates, the first rotating shaft 55 and the transmission belt 56 will slip, causing the rotary plate 57 to pause or stop rotating during the rotation process, which is not conducive to the rotary plate 57 pressing the raw material. At the same time, the rotary plates 57 need to contact each other during the rotation process, so as to achieve synchronous rotation of the rotary plates 57 on the two first rotating shafts 55. The two rotary plates 57 collide when contacting each other, causing deformation of the rotary plates 57, affecting the normal pressing action of the rotary plates 57. The present invention avoids slipping between the first rotating shaft 55 and the transmission belt 56 by providing a trapezoidal block 50 and a buffer block 58, and avoids deformation of the rotary plates 57 due to direct contact.

[0043] As an embodiment of the present invention, Figure 5 As shown, a first roller 59 is rotatably connected to the center of the buffer block 58 , and the first roller 59 is rollingly connected to the inner wall of the feed channel 51 .

[0044] During the rotation of the rotary plate 57, a gap needs to be maintained with the inner wall of the feed channel 51. In this way, the raw materials will rotate with the rotation of the rotary plate 57, and the raw materials will be retained in the gap between the rotary plate 57 and the inner wall of the feed channel 51, making it difficult to continue to participate in subsequent work. The present invention provides a roller, which rolls on the inner wall of the feed channel 51 to squeeze out the raw materials in the gap, thereby avoiding waste of raw materials.

[0045] As an embodiment of the present invention, Figure 3 As shown, the position of the feed channel 51 near the rotary plate 57 is set to be gourd-shaped, and the corner positions of the inner surface of the feed channel 51 are all set to be rounded.

[0046] In order to provide sufficient space for the rotation of the rotary plate 57 and reduce the space occupied by the feed channel 51, and ensure that the raw materials quickly fall to the position of the feed screw 54, the present invention provides a gourd-shaped feed channel 51. While ensuring the normal rotation of the rotary plate 57, the volume of the feed channel 51 is reduced, and the rounded corners are used to make the sliding process of the raw materials smoother without hooking on the inner wall of the feed channel 51.

[0047] As an embodiment of the present invention, Figure 1 , Figure 6 As shown, a discharging mechanism 6 is fixedly connected to the upper end of the outer surface of the pre-furling barrel 2 at a position away from the feeding mechanism 5, and the discharging mechanism 6 includes a discharging channel 61 fixedly connected to the pre-furling barrel 2, and two pairs of second rotating shafts 62 are symmetrically rotatably connected to the upper end of the inner surface of the discharging channel 61, and a conveyor belt 63 is wrapped around the outer surface of the two pairs of the second rotating shafts 62.

[0048] After the raw materials are foamed and formed into foam particles, their diameter will increase and their surface will be soft. When a large amount of material is discharged, the foam particles will squeeze each other in the discharge channel 61, which will cause blockage of the discharge channel 61, affecting the discharge efficiency of the foam particles, and even sudden large-scale discharge after accumulation, affecting the solidification effect of the fluidized bed. The present invention sets a discharge mechanism 6. When a large number of foam particles contact the conveyor belt 63 in the discharge channel 61, the subsequent foam particles are continuously discharged, pushing the front foam particles to descend. When the foam particles descend, static friction is generated with the outer surface of the conveyor belt 63, prompting the conveyor belt 63 to rotate. When the conveyor belt 63 rotates, the foam particles can continue to move, avoiding the situation where the foam particles are squeezed and retained, and helping the foam particle pile to be discharged.

[0049] As an embodiment of the present invention, Figure 7 As shown, a speed sensor 64 is embedded and connected at a position near the conveyor belt 63 on the outer surface of the discharge channel 61 , and a protrusion 65 is fixedly connected to the outer surface of the conveyor belt 63 .

[0050] In actual work, the discharge and feed amounts need to reach a state of dynamic balance to ensure that the foam particles that have been foamed in the pre-expander are discharged from the pre-expander barrel 2 in time. The present invention sets a speed sensor 64. When the conveyor belt 63 rotates, the protrusion 65 moves accordingly. At this time, the speed sensor 64 monitors the rotation speed of the conveyor belt 63, and then controls the rotation speed of the first motor 52 through an electrical signal, so that the feeding speed of the feed screw 54 matches the rotation speed of the conveyor belt 63 in the discharge channel 61, so that the feeding speed and the discharging speed inside the pre-expander barrel 2 reach a dynamic balance, thereby avoiding the phenomenon that the foam particles that have been foamed stay in the pre-expander barrel 2 for too long, causing the foam particles to shrink.

[0051] As an embodiment of the present invention, Figure 7 , Figure 8 As shown, a first spring 66 is fixedly connected to a position of the outer surface of the discharge channel 61 near the speed sensor 64 , and a lower end of the first spring 66 is fixedly connected to a limiting block 67 .

[0052] The speed sensor 64 is an electronic accessory and needs to be inspected and replaced regularly. To facilitate the installation and disassembly of the speed sensor 64, the present invention provides a first spring 66. When the speed sensor 64 needs to be inspected or replaced, the limit block 67 is pulled to move the limit block 67 upward, thereby compressing the first spring 66, so that the speed sensor 64 can be taken out and the speed sensor 64 can be embedded in the discharge channel 61 in the same way.

[0053] As an embodiment of the present invention, Figure 8 As shown, one end of the limit block 67 is fixedly connected to a symmetrically arranged second spring 68 , and one end of the second spring 68 is fixedly connected to a tightening block 69 , and the tightening block 69 is tightly connected to the speed sensor 64 .

[0054] In order to prevent the speed sensor 64 from lateral shaking during operation, which would result in reduced detection effect, the present invention sets a clamping block 69 to press the speed sensor 64 against the surface of the discharge channel 61 , thereby limiting the lateral displacement of the speed sensor 64 .

[0055] As an embodiment of the present invention, Figure 8 As shown, a sealing gasket 60 is fixedly connected to the position where the outer surface of the speed sensor 64 contacts the discharge channel 61, and the sealing gasket 60 is a component made of rubber material.

[0056] In actual work, in order to avoid the longitudinal shaking of the speed sensor 64, which will cause the detection effect of the speed sensor 64 to decrease, the present invention sets a sealing gasket 60, and uses the sealing gasket 60 to clamp the speed sensor 64 in the embedding groove of the discharge channel 61 to limit the longitudinal displacement of the speed sensor 64.

[0057] Instructions for use: During the use of the present invention, first, the raw material is poured into the feed channel 51, and then the first motor 52 is started. When the first motor 52 rotates, the output shaft rotates to drive the feed screw 54 to rotate, and the feed screw 54 transports the raw material into the pre-fermentation barrel 2. At the same time, the rotation of the feed screw 54 rotates the first bevel gear 53 through meshing motion, and the rotation of the first bevel gear 53 rotates the first rotating shaft 55 fixedly connected to the first bevel gear 53, and then the rotation of the first rotating shaft 55 drives the transmission belt 56 to rotate. , and then the first rotating shaft 55 at the other end rotates, and the rotation of the first rotating shaft 55 at this end rotates the rotary plate 57. During the rotation of the rotary plate 57, contact will occur, and then the pressing of the two rotary plates 57 is realized, and the raw materials at the lower end of the feeding channel 51 are pressed into the feeding screw 54, so that the raw materials can smoothly enter the pre-expansion barrel 2. At this time, the pre-expansion component 3 passes hot steam into the pre-expansion barrel 2 and stirs the raw materials in the pre-expansion barrel 2, so that the raw materials are fully in contact with the hot steam, and the foamed raw materials become foam particles. As the stirring proceeds The unfoamed raw material has a small diameter and falls to the lower layer of the accumulated raw materials. The foamed raw material has a larger diameter and is pushed by the airflow to float on the uppermost layer of the accumulated raw materials. As the raw materials foam, the accumulation of raw materials increases. The foamed particles on the uppermost layer are discharged from the pre-foaming barrel 2. After a large number of foam particles contact the conveyor belt 63 in the discharge channel 61, the conveyor belt 63 rotates due to the descent of the foam particles, which helps the discharge of the foam particle pile. When the conveyor belt 63 rotates, the protrusion 65 moves accordingly. At this time, the speed sensor 64 detects the rotation speed of the conveyor belt 63. The degree is monitored, and then the rotation speed of the first motor 52 is controlled by an electrical signal, so that the feeding speed of the feeding screw 54 matches the rotation speed of the conveyor belt 63 in the discharge channel 61, so that the feeding speed and the discharge speed inside the pre-barrel 2 reach a dynamic balance. When the speed sensor 64 needs to be repaired or replaced, the limit block 67 is pulled to move the limit block 67 upward, thereby compressing the first spring 66, and the speed sensor 64 can be taken out, and the speed sensor 64 can be embedded in the discharge channel 61 in the same way.

The present invention avoids slippage between the first rotating shaft (55) and the transmission belt (56) by arranging the trapezoidal blocks (50) and the buffer blocks (58), and avoids deformation of the rotary plates (57) due to direct contact; The buffer block (58) is rotatably connected to a first roller (59) at the center position inside the buffer block (58), and the first roller (59) is rollingly connected to the inner wall of the feed channel (51); during the rotation of the rotary plate (57), a gap needs to be retained between the rotary plate (57) and the inner wall of the feed channel (51), so that the raw material will rotate with the rotation of the rotary plate (57), and the raw material will be retained in the gap between the rotary plate (57) and the inner wall of the feed channel (51), making it difficult to continue to participate in subsequent work. The present invention provides a roller, and utilizes the roller to roll on the inner wall of the feed channel (51), so that the raw material in the gap can be squeezed out, thereby avoiding the waste of raw materials; The position of the feed channel (51) close to the rotary plate (57) is configured to be gourd-shaped, and the corner positions of the inner surface of the feed channel (51) are configured to be rounded; A discharge mechanism (6) is fixedly connected to the upper end of the outer surface of the pre-expanding barrel (2) at a position away from the feeding mechanism (5), and the discharge mechanism (6) comprises a discharge channel (61) fixedly connected to the pre-expanding barrel (2), and two pairs of second rotating shafts (62) are symmetrically rotatably connected to the upper end of the inner surface of the discharge channel (61), and a conveyor belt (63) is wound around the outer surface of the two pairs of second rotating shafts (62); A speed sensor (64) is embedded and connected to a position near the conveyor belt (63) on the outer surface of the discharge channel (61), and a protrusion (65) is fixedly connected to the outer surface of the conveyor belt (63); after a large number of foam particles contact the conveyor belt (63) in the discharge channel (61), the conveyor belt (63) rotates due to the descent of the foam particles, thereby helping the discharge of the foam particle pile. When the conveyor belt (63) rotates, the protrusion (65) moves accordingly. At this time, the speed sensor (64) monitors the rotation speed of the conveyor belt (63), and then controls the rotation speed of the first motor (52) through an electrical signal, so that the feeding speed of the feeding screw (54) matches the rotation speed of the conveyor belt (63) in the discharge channel (61), so that the feeding speed and the discharging speed inside the pre-fermentation barrel (2) reach a dynamic balance.
