Description

Technical Field

[0001] This utility model relates to the technical field of devices for coating liquids or other fluids onto surfaces, specifically a TPE anti-slip coating device for XPS board surfaces. Background Technology

[0002] XPS extruded polystyrene foam boards are widely used in building insulation, cold chain logistics and other fields due to their excellent thermal insulation and compressive strength. To improve their surface anti-slip and wear resistance, the industry generally adopts the process of coating the XPS board surface with a TPE (thermoplastic elastomer) anti-slip layer. At present, the TPE anti-slip layer coating equipment mainly uses the roller coating process. Such equipment usually includes a substrate conveying module, a TPE material processing module and a roller coating module. The conveying module realizes the continuous conveying of XPS boards through conveying rollers and conveyor belts. The material processing module completes the melting and homogenization of TPE particles through storage tanks, heating blocks and stirring blades. The roller coating module relies on coating rollers to transfer molten TPE to the XPS board surface to form an anti-slip coating.

[0003] With the increasing market demand for customized XPS board thickness (5-100mm) and stringent requirements for TPE coating thickness (0.2-1.5mm), the coating rollers of existing coating devices are mostly rigidly fixed to the rotating rollers by bearing seats and bolt groups. Disassembly and assembly require the use of special tools to remove the bearing cover and loosen multiple fastening components. After replacement, the parallelism between the coating roller and the conveyor belt and the coating gap need to be recalibrated, resulting in a long time required for each changeover. The excessively long changeover time not only reduces production efficiency, but the frequent disassembly and calibration can also easily cause problems such as axial displacement of the coating roller and fluctuation of the coating gap, which in turn leads to defects such as uneven thickness and edge missed coating in the TPE coating, affecting the coating quality.

Insertion slot 27 is collinear with the axis of rotating roller 18. The internal space of insertion slot 27 is adapted to the shape of insertion post 28. The interior of insertion slot 27 is rotatably connected to insertion post 28. Insertion slot 27 provides installation space for insertion post 28. Insertion slot 27 ensures that rotating roller 18 can rotate flexibly through rotational connection with insertion post 28. Insertion slot 27 restricts the radial displacement of insertion post 28. Insertion slot 27 ensures the installation stability of the left end of rotating roller 18. Insertion post 28: Insertion post 28 is a cylindrical rod structure. Insertion post 28 is fixedly connected to the right side of mounting block 26. The axis of insertion post 28 and mounting block 26 are collinear. Insertion post 28 extends into the interior of insertion groove 27. The external dimensions of insertion post 28 are adapted to the internal space of insertion groove 27. Insertion post 28 and insertion groove 27 cooperate to provide rotational support for the left end of rotating roller 18. Insertion post 28 ensures that the left end of rotating roller 18 can rotate flexibly. Insertion post 28 restricts the radial displacement of the left end of rotating roller 18. Insertion post 28 does not affect the normal operation of rotating roller 18. Bolt 29: There are two bolts 29, which are symmetrically arranged front and back. Both bolts 29 are installed on the left side of the mounting block 26. The threads of both bolts 29 extend into the interior of the first slider 15. The bolts 29 are adapted to the connection requirements between the mounting block 26 and the first slider 15. The bolts 29 fix the mounting block 26 to the first slider 15 through threaded connection. The bolts 29 ensure the firmness of the connection between the mounting block 26 and the first slider 15. The bolts 29 enable the detachable connection between the mounting block 26 and the first slider 15. The bolts 29 facilitate the disassembly or installation of the mounting block 26 by the operator. Second retaining ring 30: The second retaining ring 30 is fixedly sleeved on the outer surface of the rotating roller 18. The second retaining ring 30 is located at the left end of the rotating roller 18. The right side of the second retaining ring 30 contacts the left end of the limiting roller 19 and the left end of the coating roller 20 respectively. The outer dimensions of the second retaining ring 30 are adapted to the end face dimensions of the limiting roller 19 and the coating roller 20. The second retaining ring 30 axially positions the coating roller 20 and prevents the coating roller 20 from shifting to the left during rotation. The second retaining ring 30 also limits the left end of the limiting roller 19. The second retaining ring 30 cooperates with the first retaining ring 22 to ensure the axial position stability of the limiting roller 19 and the coating roller 20.

[0022] Electric push rods 31: There are two electric push rods 31, which are symmetrically arranged on the left and right. Both electric push rods 31 are fixedly connected to the upper side of the fixed frame 5. The telescopic rods of the two electric push rods 31 slide into the interior of the two sliding grooves 13 respectively. The telescopic rod of the left electric push rod 31 is fixedly connected to the first slider 15, and the telescopic rod of the right electric push rod 31 is fixedly connected to the second slider 16. The electric push rods 31 provide the power for the first slider 15 and the second slider 16 to move up and down. The electric push rods 31 drive the first slider 15 and the second slider 16 to move up and down synchronously through the extension and retraction of the telescopic rods. The electric push rods 31 control the height of the rotating roller 18 and the coating roller 20 by adjusting the extension and retraction of the telescopic rods. The electric push rods 31 adjust the gap between the coating roller 20 and the XPS board by controlling the height of the coating roller 20. Support block 32: The support block 32 is installed inside the base 1. The left and right sides of the support block 32 are fixedly connected to the left and right walls of the base 1, respectively. The support block 32 is positioned between the two conveyor rollers 2. The upper side of the support block 32 is in contact with the lower side of the conveyor belt 3. The height of the support block 32 is adapted to the installation requirements of the conveyor belt 3. The support block 32 supports the conveyor belt 3 and prevents the conveyor belt 3 from deforming due to the weight of the XPS board. The support block 32 prevents the conveyor belt 3 from sinking due to the pressure of the coating roller 20 during the coating process. The support block 32 ensures that the conveyor belt 3 can always remain horizontal, thereby ensuring the stable transport of the XPS board.

[0023] Furthermore, during the transport of XPS boards, two first motor assemblies 4 are activated. The output shafts of the first motor assemblies 4 drive two conveyor rollers 2 to rotate inside the base 1. The two conveyor rollers 2 drive the conveyor belt 3 to rotate synchronously through a transmission connection. The XPS board to be coated is placed on the conveyor belt 3. The conveyor belt 3 carries the XPS board towards the coating mechanism. The support block 32 inside the base 1 supports the conveyor belt 3 to prevent the conveyor belt 3 from deforming due to the weight of the XPS board or the subsequent coating pressure, thus ensuring the smooth transport of the XPS board.

[0024] During TPE material pretreatment, TPE granules are added to the storage tank 6 through the feed hopper 10 on the upper side of the storage tank 6. The feed hopper 10 is connected to the inside of the storage tank 6, and the raw material falls directly into the storage tank 6. The electric heating block 9 on the inner surface of the storage tank 6 is activated, which heats the TPE granules inside the storage tank 6, causing the TPE granules to melt into a flowable gel. The second motor assembly 7 on the upper side of the storage tank 6 is activated, and the output shaft of the second motor assembly 7 drives the stirring blade 8 to rotate inside the storage tank 6. The stirring blade 8 stirs the molten TPE gel material to prevent the TPE material from cooling and clumping or becoming uneven in composition, thus ensuring the stability of the TPE material. When feeding TPE material, the feeding trough 11 on the bottom wall of the storage tank 6 is connected to the inside of the fixed frame 5. The molten TPE material flows into several feeding pipes 12 on the top wall of the fixed frame 5 through the feeding trough 11. According to the width of the XPS board to be coated and the target coating thickness, the electric control valve on the feeding pipe 12 is adjusted to control the amount of TPE material flowing out of each feeding pipe 12. Several feeding pipes 12 arranged left and right evenly convey the TPE material to the surface of the coating roller 20 below. During XPS board coating, two electric push rods 31 are activated. The telescopic rods of the electric push rods 31 extend and retract within the sliding grooves 13 on both sides of the fixing frame 5, causing the first slider 15 to move up and down synchronously within the left sliding groove 13 and the second slider 16 within the right sliding groove 13. The four limiting sliders 17 on the front and rear sides of the first slider 15 and the second slider 16 slide synchronously within the four limiting grooves 14 to prevent the first slider 15 and the second slider 16 from deviating during movement and to ensure movement accuracy. The first slider 15 and the second slider 16 drive the rotating roller 18 to move up and down. Until the coating roller 20 on the outer surface of the rotating roller 18 forms a target gap with the XPS plate surface on the conveyor belt 3, the gap size matches the TPE coating thickness requirement of 0.2-1.5mm, the third motor assembly 21 is started. The output shaft of the third motor assembly 21 drives the limit block 24 to rotate. The limit block 24 rotates in the limit slot 23 at the right end of the rotating roller 18, thereby driving the rotating roller 18 to rotate synchronously. The rotating roller 18 drives the limit roller 19, which is fixedly sleeved on the outer surface, to rotate. The limit roller 19 drives the coating roller 20, which is slidably sleeved on its outer surface, to rotate. During the rotation of the coating roller 20, its surface picks up the TPE material conveyed by the feed pipe 12. As the coating roller 20 continues to rotate, it evenly presses the TPE material onto the surface of the XPS board conveyed by the conveyor belt 3 to form a TPE anti-slip coating. The first retaining ring 22 is fixedly sleeved on the outer surface of the output shaft of the third motor assembly 21, and its left side contacts the right end of the limiting roller 19 and the coating roller 20. The second retaining ring 30 is fixedly sleeved on the outer surface of the rotating roller 18, and its right side contacts the left end of the limiting roller 19 and the coating roller 20. The first retaining ring 22 and the second retaining ring 30 together axially position the coating roller 20 to prevent the coating roller 20 from shifting left or right when rotating, and to ensure that the coating width matches the width of the XPS board. If the coating roller 20 needs to be adapted to different anti-slip patterns or repaired for wear, it needs to be disassembled and replaced. First, turn off the third motor assembly 21 and the electric push rod 31 to stop the coating operation. Unscrew the two bolts 29 on the left side of the mounting block 26. The screws of the bolts 29 will come out from inside the first slider 15, releasing the fixing of the mounting block 26 to the first slider 15. Pull the mounting block 26 to the left, and the mounting block 26 will be removed from the mounting groove 25 on the left side of the first slider 15. At the same time, the insertion post 28 on the right side of the mounting block 26 will come out from the insertion groove 27 at the left end of the rotating roller 18. At this time, the rotating roller 18 will... When the left end of roller 8 loses support, the rotating roller 18 is pulled to the left. Because the limiting roller 19 is fixedly sleeved on the outer surface of the rotating roller 18, the rotating roller 18 drives the limiting roller 19 to move to the left synchronously. During the process, the limiting slot 23 at the right end of the rotating roller 18 slides out from the limiting insert 24 on the output shaft of the third motor assembly 21. The rotating roller 18 and the limiting roller 19 are removed as a whole from between the first slider 15 and the second slider 16. After the rotating roller 18 and the limiting roller 19 are removed, the coating roller 20 falls directly onto the conveyor belt 3 because it loses the sleeve support of the limiting roller 19, thus completing the removal of the coating roller 20.

[0025] When replacing the new coating roller 20, follow the reverse steps: first, slide the new coating roller 20 onto the outer surface of the limiting roller 19; then, align the limiting slot 23 on the right end of the rotating roller 18 with the limiting insert 24; next, insert the insert post 28 into the insert groove 27 and the mounting block 26 into the mounting groove 25; finally, tighten the bolt 29 to fix it, thus completing the quick replacement of the coating mechanism. Restart the equipment to resume the coating operation.

[0026] Example: High-load, long-term operation scenario Please see Figure 5 The four limiting grooves 14 are replaced from rectangular grooves to isosceles trapezoidal grooves, and the four corresponding limiting sliders 17 are replaced from rectangular blocks to isosceles trapezoidal blocks. The fixed connection relationship between the limiting sliders 17 and the first slider 15 and the second slider 16 is retained, and the opening position of the limiting grooves 14 on the sliding grooves 13 remains unchanged.

[0027] After replacement, during installation and debugging, the isosceles trapezoidal limiting slider 17 can slide smoothly into the isosceles trapezoidal limiting groove 14. Due to the characteristics of the trapezoidal structure, the limiting slider 17 can naturally form a stable locking state without the need for additional positioning components. During the coating operation, the conveyor belt 3 transports the heavy XPS board to the bottom of the coating mechanism. The electric push rod 31 drives the first slider 15 and the second slider 16 to move up and down. At this time, the isosceles trapezoidal limiting slider 17 is in close contact with the inclined surface of the isosceles trapezoidal limiting groove 14. During the movement, it can offset the lateral pressure generated by the XPS board on the coating roller 20, ensuring the stable movement of the first slider 15 and the second slider 16.

[0028] After replacement, the forward and backward offset of the limit slider 17 can be effectively reduced during operation, avoiding the problem of unstable relative position between the coating roller 20 and the XPS board due to offset. After long-term use, the "corner jamming" situation common in the original rectangular structure will not occur. There is no need to frequently grind and maintain the edge of the limit slide groove 14, which extends the maintenance cycle and reduces maintenance costs. The gap stability between the coating roller 20 and the XPS board is improved, avoiding the problem of uneven coating edge thickness caused by offset, and effectively improving the coating qualification rate of heavy XPS boards.
