Description

Technical Field

[0001] The invention belongs to the technical field of seat cushion production, and relates to a residual material cleaning unit and a high-speed rail seat cushion production system. Background Art

[0002] As the name implies, a cushion is used for sitting. For example, cushions are widely used on high-speed train seats to improve sitting comfort. Among them, the common material of high-speed train cushions is foamed foam (also called foamed sponge), that is, flexible polyurethane foam (Flexible Polyurethane Foam, referred to as polyurethane soft foam), which has a certain elasticity and its main function is cushioning. Polyurethane soft foam is commonly used in sofa furniture, pillows, cushions, toys, clothing and sound insulation lining.

[0003] At present, in the production process of polyurethane soft foam on the market, the raw materials are first injected into the same mixing chamber through different pipes (the mixing chamber is connected to a driving plate driven by a robot arm, and the bottom of the driving plate has an extruder connected to the mixing chamber), and then mixed in the mixing chamber and injected into the cavity of the upper and lower molds of the mold, or directly injected into the cavity of the upper and lower molds of the mold, and then foaming is completed in the cavity. The raw materials are injected into the injection port of the upper mold through the extruder head, and then injected into the foaming cavity through the injection port.

[0004] A vertical rod is installed between the mold and the robot arm used to move the drive plate, and then a cloth ball is installed on the top of the rod. After the extruder head has been used for a period of time, some residual materials will usually adhere to the bottom and outside of the extruder head. At this time, the robot arm needs to move the drive plate to the position of the cloth ball, and move the extruder head to the cloth ball, and use the cloth ball to wipe the extruder head to ensure the cleanliness of the extruder head. In the actual production process, the cloth ball needs to be manually replaced regularly to ensure that there is enough cloth ball area to clean the extruder head. Summary of the invention

[0100] A waste material cleaning unit as described in any one of the above items;

[0101] A mechanical arm 45, wherein a driving plate 46 is disposed at the output end of the mechanical arm 45, a mixing chamber 47 is disposed at the top of the driving plate 46, and an extrusion head 48 communicating with the mixing chamber 47 is disposed at the bottom of the driving plate 46;

[0102] A raw material pipe 49, wherein the top of the mixing chamber 47 is connected to a plurality of raw material pipes 49;

[0103] A compressed air pipe 50, the compressed air pipe 50 is connected to the top or side of the mixing chamber 47, and is used to inject compressed air into the mixing chamber 47 and blow the material into the injection port 56, or blow it into the outside to clean the inner wall of the mixing chamber 47;

[0104] A bottom support platform 51 and a top support platform 52 horizontally rotatably connected to the top of the bottom support platform 51, a motor (preferably a reduction motor) for driving the top support platform 52 to rotate is disposed in the middle of the bottom support platform 51, and the support column 1 is located between the bottom support platform 51 and the mechanical arm 45;

[0105] A lower mold 53, wherein a plurality of lower molds 53 are disposed on the supporting platform 52;

[0106] Support frame 54, a plurality of support frames 54 are arranged on the top support platform 52, each of the inner sides of the lower mold 53 has a support frame 54, each of the support frames 54 is hingedly provided with an upper mold 55, and each of the upper molds 55 is provided with an injection port 56 for communicating with the extrusion head 48 at the top;

[0107] The driving member 57 has a bottom hinged to the supporting platform 52 and a top hinged to the upper side of the upper mold 55. The driving member 57 is preferably a cylinder, an electric push rod, etc. If it is a cylinder, an air pump is provided in the middle of the supporting platform 52. The supporting platform 52 does not rotate continuously in one direction, but rotates clockwise and counterclockwise in a circular manner, so as to prevent the entanglement of wires or air pipes, etc., and reduce the difficulty of equipment production and use.

[0108] During production, the robot arm 45 moves the drive plate 46 to the upper mold 55 of the mold, and connects the extruder head 48 with the injection port 56. After the valve on the corresponding raw material pipe 49 is opened, the pump on the raw material pipe 49 inputs the corresponding raw material into the mixing chamber 47, and injects it into the cavity formed by the upper mold 55 and the lower mold 53 through the extruder head 48 and the injection port 56 for foaming. After the foaming is completed, the drive member 57 drives the upper mold 55 to rotate and separate from the lower mold 53. At this time, the worker can take out the product in the cavity and move it to other stations for subsequent processing. After the product is taken out, the drive member 57 drives the upper mold 55 to rotate and close the mold with the lower mold 53, waiting for the next use.

[0109] A residual material cleaning unit provided by the present invention is located between the foaming mold and the robot arm 45 when actually used; during the processing, after the robot arm 45 moves the driving plate 46, the extrusion head 48 on the driving plate 46 is connected with the injection port 56 of the upper mold 55, and then the raw material pipe 49 injects the raw material into the mixing chamber 47, and after passing through the mixing chamber 47 and the extrusion head 48, it enters the cavity of the upper mold 55 and the lower mold 53 through the injection port 56, and is foamed and formed in the upper mold 55 and the lower mold 53.

[0110] When the extruder head 48 is regularly cleaned, the mechanical arm 45 moves the driving plate 46, and the extruder head 48 is acted on the cleaning member 7 (consumable material, preferably a material with lower cost such as cloth) on the top of the support plate 3, and the cleaning member 7 remains in place, and the mechanical arm 45 drives the extruder head 48 to rub on the cleaning member 7, so that the residual material on the extruder head 48 can be cleaned up. After cleaning up, the mechanical arm 45 removes the driving plate 46 and the extruder head 48 for injection in the next process, and the driving mechanism drives the winding roller 5 to rotate, and more cleaning members 7 are wound on the winding roller 5, and the cleaning members 7 of corresponding length are released from the unwinding roller 6. Since the cleaning member 7 with a very long length can be installed on the winding roller 5 at each time, the cycle or frequency of replacing the cleaning member 7 can be greatly reduced, and the use effect is better. Secondly, if it is necessary to recycle the cleaning piece 7 after cleaning, since the cleaning piece 7 with residual material stuck on it after cleaning is rolled up on the winding roller 5, it is convenient to move the cleaned cleaning piece 7 or clean it. For example, when cleaning, the winding roller 5 is fixed to a certain bracket, and then its free end is pulled, so that the cleaning piece 7 in the middle is cleaned with various reagents and combined with physical cleaning. Finally, the cleaned cleaning piece 7 is dried and rewound, and then it can be used as the cleaning piece 7 on the new unwinding roller 6, and the comprehensive use effect is better.

[0111] When actually cleaning the extruder head 48, first the mechanical arm 45 moves the driving plate 46 to the top of the clamping strip 15 and then moves downward. During the downward movement, the bottom of the driving plate 46 first acts on the top of the two clamping strips 15, driving the clamping strips 15 to move downward. At the same time, the clamping strip 15 also drives the gear body 14 to move downward, and the gear body 14 rotates after being acted on by the rack body 16, so that the action process of the clamping strip 15 is to swing downward while moving downward. Before the driving plate 46 drops to the lowest height, the driving plate 46 moves slightly in the direction away from the rack body 16 to prevent the subsequent driving plate 46 from acting on the rack body 16 and the gear body 14, ensuring that the extruder head 48 can smoothly act on the cleaning member 7.

[0112] When the clamping strip 15 rotates to a nearly horizontal state, its lower side has already acted on the top of the cleaning piece 7, and then the driving plate 46 moves slightly downward a small distance, so that the clamping strip 15 continues to move downward until it moves to a horizontal state. At this time, the bottom deformation body 8 (having a certain thickness and elasticity, preferably rubber, silicone or other conventional materials) is pressed and deformed by the two clamping strips 15, which not only improves the clamping stability of the clamping strip 15 on the cleaning piece 7, but also the bottom of the extrusion head 48 is lower than the bottom of the two clamping strips 15 at this time, so that the bottom of the extrusion head 48 is also sunk into the deformed deformation body 8 (the cleaning piece 7 and the deformation body 8 are both elastically deformed and not damaged; the degree of deformation is small, and the impact on the overall use of the cleaning piece 7 can be ignored). In this way, the cleaning piece 7 has a better wrapping effect on the extrusion head 48, which can not only clean the bottom of the extrusion head 48, but also clean its edge and inner side to a certain extent, so that the overall cleaning effect is better. When cleaning, preferably, the extruder 48 and the drive plate 46 reciprocate along the length direction of the compression strip 15, so that the cleaning effect is better. Since the extruder 48 presses the cleaning member 7 to deformation, when it slides relative to the cleaning member 7, a larger force will be applied to the cleaning member 7, but since the two sides of the extruder 48 are compressed by the compression strip 15, the position stability of the cleaning member 7 can be fully guaranteed.

[0113] When the driving plate 46 just acts on the top of the compression strip 15, the drag reducing beads 43 on the top of the compression strip 15 can facilitate the movement of the compression strip 15 relative to the driving plate 46; at the same time, in the subsequent process of cleaning the extruder head 48, the drag reducing beads 43 on the upper side of the compression strip 15 can greatly reduce the resistance between the driving plate 46 and the compression strip 15, which not only reduces the generation of noise, but also protects the two.

[0114] Before the driving plate 46 is pressed down to the pressing strip 15, the positioning thorn body 31 at this moment passes through the cleaning member 7, or the positioning thorn body 31 and the positioning groove body clamp the cleaning member 7. Then in the process of the pressing strip 15 moving downward, the swing wheel 36 (preferably made of materials such as rubber or silica gel, which can generate a larger static friction force with the swing part 34, and the swing part 34 can drive the swing wheel 36 to rotate) is subjected to the effect of the swing part 34 and rotates, and the positioning strip 30 is separated from the cleaning member 7. Wherein at this moment, the swing wheel 36 also drives the first turning roller 17 to rotate, but because the sliding friction force between the first cylinder 24 and the winding roller 5 is larger, the first turning roller 17 can only slide relative to the cleaning member 7, and the cleaning member 7 and the support plate 3 and the winding roller 5 all remain relatively static.

[0115] Before the pressing strip 15 is pressed down to the horizontal state, the swing wheel 36 is separated from the swing part 34. At this time, the swing wheel 36 is not subjected to external force, so the swing arm and the positioning strip 30 will not rotate further. In addition, the force applied by the booster cylinder 42 to the first steering roller 17 keeps the linkage arm 29 in an inclined state to prevent it from excessive rotation. When the pressing strip 15 is pressed down to the horizontal state, the linkage arm 29 contacts the top of the termination strip 35, and the positioning strip 30 and the cleaning member 7 are separated. The swing wheel 36 and the swing part 34 are also separated, and the angle between the linkage arm 29 and the horizontal plane is fixed.

[0116] During the entire downward process of the support seat 2, the support seat 2 is buckled on the support platform 10 through the lifting groove 11 at its bottom, so that the support seat 2 can only be lifted vertically; at the same time, the passive disk 21 is also driven downward by the winding roller 5, and during its downward process, part of the one-way member 23 acts on the upper side of the linkage tooth 20, wherein the inclination direction of this part of the one-way member 23 is the same as the inclination direction of the upper side of the linkage tooth 20, and at this time, the corresponding terminal seats 22 of the one-way member 23 are all located below it, so when the passive disk 21 descends, the one-way member 23 can only swing back and forth under the dual action of the upper side of the linkage tooth 20 and the reset torsion spring, and cannot drive the passive disk 21 and the winding roller 5 to rotate (there is friction between the winding roller 5 and the connecting plate 4, and when the passive disk 21 descends, the force acting on the one-way member 23 is less than the friction, so the winding roller 5 maintains the angle unchanged).

[0117] After the extruder head 48 is cleaned, the drive plate 46 moves upward and separates from the clamping strip 15. At this time, the support seat 2 is raised under the elastic force of the elastic member 12, and the passive disk 21 is also raised during the raising process. At this time, the one-way member 23 (one or more) acting on the lower side of the linkage tooth 20 is affected by the linkage tooth 20 and rotates, and drives the first cylinder 24 to reel in. That is, when the support plate 3 is raised, automatic reeling is achieved under the joint action of the passive disk 21, the linkage column 19, the linkage tooth 20, etc.

[0118] During the winding process, the first cylinder 24 also drives the second cylinder 25 and the first and second steering rollers 17 and 18 to rotate, wherein the booster cylinder 42 enables sufficient force between the cleaning member 7 and the first steering roller 17, so that the first steering roller 17 can drive the linkage arm 29 and the positioning bar 30 to move, and when the support plate 3 is raised to a corresponding height, the positioning thorn 31 passes through the cleaning member 7 or the positioning thorn 31 and the positioning groove body clamp the cleaning member 7; at this time, the support plate 3 has not yet been raised to the highest state, and the swing wheel 36 preferably has not yet acted on the swing part 34. Afterwards, since the cleaning member 7 is fixed in position by the positioning thorn 31, during the subsequent raising process of the support plate 3, the first cylinder 24 can only slide relative to the winding roller 5, and prevent too many cleaning members 7 from being wound on the winding roller 5.

[0119] In actual use, as the use time increases, the diameter of the cleaning member 7 on the outer wall of the first cylinder 24 becomes larger and larger, and the height of the passive disk 21 rising in each cycle is fixed, so the rotation angle of the winding roller 5 during the rising process is fixed. When the cleaning member 7 passes over the first turning roller 17, the swing arm and the positioning bar 30 are also driven to move.

[0120] Moreover, in actual use, the length of the swing arm can be designed according to the diameter of the extruder head 48, and the length of the cleaning piece 7 released each time can be slightly larger than the diameter of the extruder head 48. This can not only further improve the utilization rate of the cleaning piece 7, but also design the position of the clamping strip 15 above the winding roller 5, so that the clamping strip 15 is pressed against the cleaning piece 7 that does not contact the residual material each time, thereby achieving a better use effect.

[0121] After the positioning thorn body 31 fixes the position of the cleaning member 7, the support plate 3 is still very high, and at a certain node, the swing wheel 36 acts on the side of the swing part 34, but because the positioning bar 30 is limited by the positioning plate 32 at this time, the swing wheel 36 cannot rotate, that is, the swing wheel 36 and the swing part 34 can only slide relative to each other; at the same time, the two can also play a buffering role for the force of the elastic member 12, and finally can protect the pressing bar 15 and the tooth bar body 16. When the support plate 3 is raised to the highest height, the outer side of the pressing bar 15 contacts the side of the tooth bar body 16, and because the gear body 14 cannot continue to rotate, the support plate 3 cannot continue to rise; at the same time, the elastic member 12 is still in a compressed state.

[0122] The two ends of the first cylinder 24 are respectively limited by the first limiting platform 26 and the first limiting member 27, so that there can be a certain distance between the cleaning member 7 and the gear body 14, so that the extruder head 48 can act on the width of the entire cleaning member 7, thereby improving the utilization rate of the cleaning member 7; secondly, the position stability of the first cylinder 24 is also improved. Similarly, the second limiting platform and the second limiting member 28 can also improve the position stability of the second cylinder 25. At the same time, the first limiting member 27 and the second limiting member 28 are preferably Ω-shaped elastic buckles or iron wires, and holes are opened on the winding roller 5 and the unwinding roller 6; after the first limiting member 27 and the second limiting member 28 pass through the corresponding holes, the first limiting member 27 and the second limiting member 28 are swung to prevent the first limiting member 27 and the second limiting member 28 from escaping from the holes; at this time, the first limiting member 27 and the second limiting member 28 can limit the outer sides of the first cylinder 24 and the second cylinder 25. When the cleaning member 7 is removed, it is only necessary to remove the first stopper 27 and the second stopper 28, which is simple and convenient. In another embodiment, the first stopper 27 and the second stopper 28 are both bolts, which are connected to the winding roller 5 and the unwinding roller 6 respectively, and then the first cylinder 24 and the second cylinder 25 can be limited.

[0123] At the same time, when replacing the cleaning member 7, the fixing portion 9a can be opened by simply lifting the plug plate 9b upward. When installing a new cleaning member 7, the second cylinder 25 is sleeved onto the unwinding roller 6, and then the positioning bolt 41 is unscrewed, and the boost column is rotated upward to allow the free section of the cleaning member 7 to pass around the first steering roller 17 and the second steering roller 18, and then be fixedly connected to the first cylinder 24 (for example, using adhesive tape); then the boost column and the positioning block 40 are rotated downward, and the positioning bolt 41 is passed through the positioning block 40 and then threadedly connected to the positioning seat 38.

[0124] In another embodiment, the cleaning process of the extruder head 48 and the cleaning member 7 is point cleaning, that is, when cleaning, the extruder head 48 only acts on a point (or a very small range) on the cleaning member 7, rather than reciprocating swing cleaning. At this time, there is no need for the drive plate 46 to act on the pressing strip 15 every time, but only when the cleaning member 7 needs to move the position, it acts on the pressing strip 15. Specifically, in the first multiple cleaning processes within the use cycle of a small section of the cleaning member 7, the drive plate 46 drives the extruder head 48 to directly act on the cleaning member 7 on the support plate 3; then when the position of the cleaning member 7 needs to be moved, the drive plate 46 acts downward on the pressing strip 15, and then the extruder head 48 at this time moves to a clean and unused place on the cleaning member 7; then after using the clean place of the cleaning member 7 to clean the extruder head 48, the drive plate 46 goes up, and the cleaning member 7 automatically moves a fixed distance toward the winding roller 5, and then the extruder head 48 can have a clean cleaning member 7 for use, and so on.

[0125] It should also be noted that all the "settings" and similar descriptive words in this application (especially the specification) express that there is or exists a connection relationship between two structures, but there is no excessive limitation on the specific means by which the two are connected, and it is usually a conventional connection means, that is, it should be understood that the means are prior art and there is no need for excessive elaboration. For example, "n is set on m" only expresses that there is n structure on m structure, and the two are specifically connected by welding, riveting, adhesive connection or integral molding, which are all within the protection scope of this application; for another example, "y is rotatably set on x" only expresses that y and x can rotate relative to each other, and whether the two are connected by bearing rotation, or y directly passes through x and is connected to x rotationally, or other feasible methods, are all within the protection scope of this application.
