Description

Technical Field

[0001] This application relates to the technical field of polyurethane foaming equipment, and in particular to a fully automatic polyurethane foaming equipment. Background Technology

[0002] Currently, when factories produce polyurethane insoles or similar products, they typically use a polyurethane foaming machine to inject the prepared foaming material into a mold. After the material foams and solidifies in the mold, a complete foamed sheet is obtained. Then, the workers remove the foamed sheet from the mold, and finally, after cutting, the desired product is obtained.

[0003] In actual production, the above-mentioned molds usually need to be fixedly installed on the mold frame, which supports and fixes the molds. However, after the polyurethane foaming machine injects the raw material into the mold, it is necessary to wait for the raw material in the mold to foam and form. This process takes about 4-5 minutes. Finally, the foamed sheet in the mold is taken out. Only then can the polyurethane foaming machine continue to carry out the next round of injection. This results in low overall production efficiency, which is difficult to adapt to the needs of mass production in factories. Summary of the Invention

[0004] This application provides a fully automatic polyurethane foaming equipment, which can greatly improve production efficiency and thus meet the needs of mass production in factories.

[0005] The fully automatic polyurethane foaming equipment provided in this application adopts the following technical solution: A fully automatic polyurethane foaming equipment, comprising: An automatic mold frame is used for mold installation, and multiple automatic mold frames are provided; A fully automated conveyor production line, wherein the automatic mold frames are sequentially arranged on the fully automated conveyor production line along the conveying direction of the fully automated conveyor production line; the fully automated conveyor production line is used to drive the automatic mold frames to move back and forth along a designated path. An automatic injection mechanism is mounted on the sliding path of the automatic mold frame and is used to inject material into the automatic mold frame as it moves to the designated station. An automatic part-removing mechanism is mounted on the sliding path of the automatic mold frame and is used to remove the foamed sheet material after foaming from the mold on the automatic mold frame.

[0006] By adopting the above technical solution: During operation, the fully automated conveyor production line is controlled to move the automatic mold frame to be injected to the underside of the automatic injection mechanism. Then, the automatic injection mechanism injects material into the automatic mold frame that has moved to the designated workstation. After the automatic injection mechanism completes the injection, the fully automated conveyor production line will restart and continue to move the injected automatic mold frame forward until the next automatic mold frame to be injected is moved to the injection workstation. At this time, the automatic injection mechanism can continue to perform the injection work, which can greatly shorten the idle time of the automatic injection mechanism and greatly improve production efficiency. After the raw material on the automatic mold frame is foamed and formed, the foamed sheets are sequentially removed from their respective molds by the automatic part removal mechanism set on the sliding path of the automatic mold frame.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This application discloses a fully automated polyurethane foaming equipment.

[0021] Reference Figure 1 , Figure 2 A fully automatic polyurethane foaming equipment includes an automatic mold frame 1, a fully automatic conveying production line 2, an automatic injection mechanism 3, an automatic part removal mechanism 4, and an automatic release agent spraying mechanism 5. The automatic part removal mechanism 4 is mounted on the sliding path of the automatic mold frame 1 and is used to remove the foamed sheet after it has been foamed from the mold set on the automatic mold frame 1.

[0022] like Figure 3 , Figure 4 As shown, at least two sets of fully automated conveyor production lines 2 are provided, and the fully automated conveyor production lines 2 are arranged side by side in sequence. This embodiment uses two sets of fully automated conveyor production lines 2 as an example. Each set of fully automated conveyor production lines 2 includes a base 20 for placement on the ground. Two tracks 21 arranged symmetrically on the left and right sides are fixedly installed on the base 20, and the length direction of the tracks 21 extends along the length direction of the base 20. Automatic mold frames 1 are slidably arranged on their respective bases 20 along the length direction of the tracks 21. Multiple rollers 15 are rotatably arranged on the bottom outer wall of the automatic mold frames 1, facing the tracks 21, and the rollers 15 are rolled on their respective opposite tracks 21.

[0023] like Figure 3 , Figure 5As shown, a mounting bracket 200 is fixedly mounted on one end of the base 20 along its length. A power unit 22 is mounted on the mounting bracket 200. The power unit 22 includes a servo motor 220 and a reducer 221 fixedly mounted on the mounting bracket 200. The input end of the reducer 221 is connected to the rotating shaft of the servo motor 220, and the reducer 221 is used to reduce the speed of the servo motor 220. Finally, the required speed is output through the output end of the reducer 221. A drag chain 23 is connected to the output end of the reducer 221 via gear transmission. The length of the drag chain 23 extends along the length of the base 20.

[0024] like Figure 3 , Figure 4 , Figure 5 As shown, multiple sets of chain rollers 24 are rotatably arranged along the length of the track 21 on the base 20. The chain rollers 24 are located between the two tracks 21 on both sides. Each set of chain rollers 24 consists of two rollers, and the two chain rollers 24 in the same set are arranged vertically. The chain rollers 24 are located on the transmission path of the drag chain 23, and the drag chain 23 is wrapped around the outside of the chain rollers 24 in sequence. The drag chain 23 meshes with its corresponding chain roller 24, and the chain rollers 24 provide support and guidance for the drag chain 23. Multiple automatic mold frames 1 are provided on the base 20. The automatic mold frames 1 located on the same base 20 are arranged in sequence along the transmission direction of the drag chain 23, and the bottom of the automatic mold frames 1 is fixedly mounted on the lower drag chain 23 in sequence.

[0025] When the drag chain 23 rotates under the drive of the servo motor 220, the drag chain 23 will pull the automatic mold frame 1 to slide back and forth along the length of the track 21.

[0026] like Figure 4 , Figure 6 As shown, the automatic mold base 1 includes a mold base 10 at the bottom, a lower mold base 11 disposed above the mold base 10, and an upper mold base 12 for mutually covering the lower mold base 11. Rollers 15 are rotatably mounted on the bottom of the mold base 10, and the mold to be injected is fixedly mounted on the lower mold base 11 and the upper mold base 12 respectively. The lower mold base 11 is rotatably mounted on the mold base 10 on one side, and the rotation axis of the lower mold base 11 extends along the length direction of the lower mold base 11. A lifting cylinder 100 is rotatably mounted on the side of the mold base 10 opposite to the rotation axis of the lower mold base 11, and the rotation axis of the lifting cylinder 100 extends along the length direction of the lower mold base 11. The piston rod of the lifting cylinder 100 is rotatably mounted on the lower mold base 11, and the rotation axis of the piston rod of the lifting cylinder 100 also extends along the length direction of the lower mold base 11. The lifting cylinder 100 is used to drive the lower mold frame 11 to rotate around the rotation axis between it and the mold base 10, and the lifting cylinder 100 is used to drive one side of the lower mold frame 11 to rise and fall on the mold base 10.

[0027] Before the injection process, the automatic injection mechanism 3 raises one side of the lower mold frame 11 by controlling the piston rod of the lifting cylinder 100 to tilt the bottom wall of the lower mold frame 11. Then, the automatic injection mechanism 3 injects the raw material to the highest point of the bottom wall of the lower mold frame 11. Since the bottom wall of the lower mold frame 11 is tilted at this time, the raw material can cover the bottom wall of the lower mold frame 11 under its own weight. Therefore, there is no need to adjust the injection position of the automatic injection mechanism 3 back and forth. This facilitates the injection process and ensures that the raw material covers the side wall of the mold, making the foaming of the finished product more uniform.

[0028] like Figure 4 , Figure 6 As shown, the upper mold frame 12 is located above the lower mold frame 11. One end of the upper mold frame 12 is rotatably mounted on the lower mold frame 11, and the rotation axis of the upper mold frame 12 extends along its length. Two opening and closing cylinders 13 are rotatably mounted on the lower mold frame 11, symmetrically arranged on the left and right sides of the lower mold frame 11. The rotation axis of the opening and closing cylinders 13 on the lower mold frame 11 extends along the length of the lower mold frame 11, and the piston rod of the opening and closing cylinders 13 faces the upper mold frame 12 and is rotatably connected to the upper mold frame 12. The rotation axis of the piston rod of the opening and closing cylinders 13 extends along the length of the upper mold frame 12. During operation, the two opening and closing cylinders 13 located on the same lower mold frame 11 will maintain synchronous operation. The opening and closing cylinders 13 are used to drive the upper mold frame 12 to rotate around the rotation axis between it and the lower mold frame 11, moving towards or away from the lower mold frame 11.

[0029] like Figure 4 , Figure 6 As shown, a connecting rod 120 is rotatably mounted on the upper mold frame 12, and the rotation axis of the connecting rod 120 extends along the length of the upper mold frame 12. A locking element 121 is fixedly mounted on the connecting rod 120, and the locking element 121 is rotatably mounted on its respective upper mold frame 12 following the connecting rod 120. A locking tongue 110 located on the rotation path of the locking element 121 is fixedly mounted on the outer wall of the lower mold frame 11 near the outer wall of the locking element 121. A locking groove 122 for the locking tongue 110 to be inserted is provided on the side wall of the locking element 121 facing the locking tongue 110.

[0030] like Figure 4 , Figure 6 As shown, a locking cylinder 14 is also rotatably mounted on the upper mold frame 12. The rotation shaft of the locking cylinder 14 extends along the length of the upper mold frame 12, and the piston rod of the locking cylinder 14 faces the locking fastener 121. The piston rod of the locking cylinder 14 is rotatably mounted on the respective locking fastener 121. The piston rod of the locking cylinder 14 is used to drive the locking fastener 121 to rotate towards or away from the locking tongue 110.

[0031] When the upper mold frame 12 is driven by the opening and closing cylinder 13 to close with the lower mold frame 11, the locking cylinder 14 is activated to rotate the locking element 121 around the connecting rod 120 towards the locking tongue 110. Finally, the locking tongue 110 is inserted into the locking groove 122. Through the mutual insertion and engagement of the locking tongue 110 and the locking element 121, the closed lower mold frame 11 and upper mold frame 12 are locked and fixed. After the foaming process is completed, the piston rod of the locking cylinder 14 is controlled to retract. As the locking element 121 rotates away from the locking tongue 110, the locking tongue 110 exits from the locking groove 122, thus releasing the lock on the lower mold frame 11 and upper mold frame 12.

[0032] like Figure 7 , Figure 8 As shown, the automatic injection mechanism 3 includes a horizontal beam 30 mounted above each set of machine bases 20, with the length direction of the beam 30 perpendicular to the length direction of the lower machine base 20. A linear guide rail 31 is fixedly mounted on the beam 30, extending along the length direction of the beam 30. The automatic injection mechanism 3 also includes an automatic pouring assembly 32 slidably mounted on the linear guide rail 31 along its length. The automatic pouring assembly 32 includes multiple inlets for communicating with the outlet of the polyurethane foaming machine, and a solenoid valve for controlling the opening and closing of the outlet of the pouring pipe. The outlet of the pouring pipe faces downward toward the automatic mold frame 1.

[0033] like Figure 7 , Figure 8 As shown, the automatic pouring assembly 32 is located on the sliding path of the automatic mold frame 1, and the automatic pouring assembly 32 is used to pour material into the automatic mold frame 1 that has moved to the designated pouring station.

[0034] like Figure 7 , Figure 8 As shown, an automatic pouring assembly 32 is also fixedly mounted with a motor for driving the automatic pouring assembly 32 to slide along the length direction of the linear guide rail 31. A rack is provided on the outer wall of the crossbeam frame 30 facing the motor output shaft, and the length direction of the rack extends along the length direction of the linear guide rail 31. A gear is coaxially mounted on the output shaft of the motor, and the motor meshes with the rack through the gear. During operation, as the motor rotates, the automatic pouring assembly 32 can slide back and forth along the length direction of the rack outside the crossbeam frame 30 under the drive of the motor. The automatic pouring assembly 32 is also equipped with a cylinder for driving each pouring pipe to move synchronously up and down in the vertical direction.

[0035] After the automatic casting assembly 32 completes the casting process for the automatic mold frame 1 on one set of bases 20, which has moved to the designated casting station, the automatic casting assembly 32 will move under the drive of a motor to another set of bases 20, moving above the automatic mold frame 1 at the designated casting station. At this time, the automatic casting assembly 32 will continue the casting process for the automatic mold frame 1 below. Meanwhile, the automatically mold frame 1, which has already been cast, will be simultaneously moved out of the casting station under the drive of its respective fully automatic conveyor production line 2. By setting up multiple sets of fully automatic conveyor production lines 2, the time spent by the fully automatic conveyor production line 2 in moving the automatic mold frame 1 is fully utilized, and the casting process of the automatic casting assembly 32 will not be affected during this period, thereby greatly improving production efficiency.

[0036] like Figure 7 , Figure 8 As shown, an automatic release agent spraying mechanism 5 is provided on the outer wall of the crossbeam frame 30 away from the automatic casting assembly 32. The automatic release agent spraying mechanism 5 is also slidably mounted on the crossbeam frame 30 along its length under the drive of a motor. The automatic release agent spraying mechanism 5 includes multiple spray guns for spraying release agent onto the inner wall of the mold on the automatic mold frame 1, and cylinders for driving the spray guns to move vertically up and down. The nozzle of the spray gun faces the lower automatic mold frame 1. When the automatic mold frame 1 to be injected moves below the spray gun, the release agent is evenly sprayed onto the inner wall of the lower mold frame 11 through the spray gun, thereby ensuring that the automatic part removal mechanism 4 can smoothly remove the molded foamed sheet from the mold of the lower mold frame 11 later.

[0037] like Figure 2 , Figure 8 , Figure 9 As shown, the automatic part-picking mechanism 4 is located on the side of the automatic release agent spraying mechanism 5 away from the automatic pouring assembly 32. The automatic part-picking mechanism 4 includes a horizontal frame 40 erected above each set of machine bases 20 in a horizontal direction, and the length direction of the horizontal frame 40 is consistent with the length direction of the crossbeam frame 30. The automatic part-picking mechanism 4 also includes a mounting plate 400, which is slidably mounted on the horizontal frame 40 along the length direction of the horizontal frame 40. A material-gripping assembly 41 is provided on the mounting plate 400.

[0038] like Figure 9 , Figure 10 as well as Figure 11As shown, a drive motor 42 for driving the mounting plate 400 to slide outside the crossbeam 40 is fixedly mounted on the mounting plate 400. A gear disk 420 is coaxially mounted on the output shaft of the drive motor 42. A rack frame 43 is fixedly mounted on the outer wall of the crossbeam 40 facing the mounting plate 400, and the length of the rack frame 43 extends along the sliding direction of the mounting plate 400. The gear disk 420 and the rack frame 43 mesh with each other. By starting the drive motor 42, the gear disk 420 is driven to rotate. As the gear disk 420 rotates, the mounting plate 400 can be moved along the length direction of the rack frame 43 through the cooperation of the gear disk 420 and the rack frame 43. By changing the rotation direction of the gear disk 420, the sliding direction of the mounting plate 400 can be controlled.

[0039] like Figure 10 , Figure 12 As shown, a drive cylinder 411 is fixedly installed on the outer wall of the mounting plate 400 away from the crossbeam frame 30. The piston rod of the drive cylinder 411 is vertically downward, and a clamping frame 44 located outside the mounting plate 400 is fixedly installed on the piston rod of the drive cylinder 411. The clamping frame 44 moves up and down vertically under the drive of the drive cylinder 411. Multiple pneumatic grippers 410 for clamping the foamed sheet are installed below the clamping frame 44. The number of pneumatic grippers 410 can be increased or decreased according to the actual specifications of the foamed sheet. In this embodiment, the pneumatic grippers 410 are arranged in pairs and are spaced apart along the length of the clamping frame 44. Two pneumatic grippers 410 in the same group are symmetrically arranged on both sides of the clamping frame 44 along the width direction.

[0040] like Figure 10 , Figure 12 As shown, a screw 45 is coaxially fixedly mounted on the pneumatic gripper 410. A plurality of oblong holes 440, corresponding one-to-one with the positions of the pneumatic gripper 410, are passed through the clamping frame 44. The oblong holes 440 are used for the respective screws 45 to pass through. The screws 45 are slidably disposed within the oblong holes 440 along their length. Multiple fasteners 450 are threaded onto the external of the screws 45; in this embodiment, nuts are used as fasteners 450. The fasteners 450 threaded onto the same screw 45 are located on both sides of the oblong hole 440, and the screw 45 is tightened and fixed to the clamping frame 44 by the fasteners 450 on both sides. By adjusting the fixing positions of the fasteners 450 on both sides, the height of the pneumatic gripper 410 can be adjusted vertically.

[0041] like Figure 10 , Figure 12As shown, the material gripping assembly 41 also includes multiple suction cups 412 for adsorbing onto the surface of the foamed sheet. The suction cups 412 are detachably mounted on the bottom of the clamping frame 44, and are symmetrically arranged on both sides of the clamping frame 44 along the width direction. The top of the suction cup 412 is connected to an air extraction pipe 413, and the end of the air extraction pipe 413 away from the suction cup 412 is connected to the air extraction port of an air pump.

[0042] When the pneumatic gripper 410 holds the foamed sheet, it ensures that the air intake at the bottom of the suction cup 412 is in contact with the surface of the foamed sheet. Then, by activating the vacuum pump, the air inside the suction cup 412 is extracted under the action of the vacuum pipe 413, creating a negative pressure inside the suction cup 412. At this point, the suction cup 412 can adhere and fix itself to the foamed sheet. Using the suction cup 412 to adhere the foamed sheet makes it easier to remove the foamed sheet from the mold and reduces damage to the surface of the foamed sheet.

[0043] The implementation principle is as follows: During operation, the fully automatic conveyor production line 2 is controlled to move the automatic mold frame 1 to be filled to the underside of the automatic injection mechanism 3. Then, the automatic injection mechanism 3 injects material into the automatic mold frame 1 at the designated workstation. After the automatic injection mechanism 3 completes the injection, the fully automatic conveyor production line 2 restarts and continues to move the filled automatic mold frame 1 forward until the next automatic mold frame 1 to be filled is moved to the injection workstation. During this process, the automatic casting component 32 moves along the crossbeam frame 30 to the top of another set of fully automatic conveyor production lines 2. At this time, the automatic injection mechanism 3 can continue to inject material into the automatic mold frames 1 on that set of fully automatic conveyor production lines 2, thus greatly shortening the idle time of the automatic injection mechanism 3, realizing alternating operation of the automatic injection mechanism 3, and greatly improving production efficiency. After the raw material on the automatic mold frame 1 is foamed and formed, the foamed sheets are sequentially removed from their respective molds by the automatic part removal mechanism 4 mounted on the sliding path of the automatic mold frame 1. After all the foamed sheets are removed, the automatic mold frame 1 is moved in the opposite direction by the fully automatic conveyor production line 2 to carry out a new round of production, thereby ensuring production efficiency and meeting the needs of mass production in the factory; the degree of automation is high, which frees up manpower.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
