[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 8 A foam packaging box processing equipment comprises a processing table 1, the top of the processing table 1 is rotatably connected to a work station 2, a lower mold 21 is fixedly connected to the work station 2, a hydraulic cylinder 3 is fixedly connected to the processing table 1, a mounting plate 31 is fixedly connected to the top of the telescopic end of the hydraulic cylinder 3, an upper mold 32 is fixedly connected to the side wall of the mounting plate 31, an injection tank 4 is fixedly connected to the top of the mounting plate 31, and a discharge pipe of the injection tank 4 is connected to the top of the inner cavity of the upper mold 32. It also includes: a cooling component, which is arranged in the lower mold 21, and the cooling component is used to quickly cool and shape the foam packaging box after injection molding; a back-blowing component, which is arranged in the lower mold 21, and the back-blowing component is used to demold the foam packaging box after molding.

[0038] Reference Figure 1-Figure 4The cooling assembly includes a water cooling tank 5, which is provided in the lower mold 21, and the lower mold 21 is provided with three groups of water cooling tanks at equal intervals. A liquid storage tank 51 is provided in the middle of the station plate 2, and an isolation sleeve 511 is fixedly connected to the liquid storage tank 51. A liquid pressure plate 52 is sealed and slidably connected between the inner walls of the isolation sleeve 511. The top of the inner cavity of the liquid storage tank 51 is connected to the bottom of the inner cavity of the water cooling tank 5 through a liquid guide groove 53. The side wall of the upper mold 32 is fixedly connected to the liquid storage tank 51. A pressure plate 54 is connected, and the extrusion end of the pressure plate 54 is located directly above the liquid pressure plate 52; three groups of limit grooves 55 are evenly spaced on the work station 2, and a limit rod 551 is fixedly connected in the limit groove 55, and a first spring 552 is sleeved on the limit rod 551.

[0039] By setting the above structure, when the upper mold 32 moves downward, the pressure plate 54 will squeeze the pressure plate 52, so that the pressure plate 52 slides downward along the isolation sleeve 511, thereby squeezing the coolant in the isolation sleeve 511, so that the coolant level in the liquid storage tank 51 rises and enters the water cooling tank 5 along the liquid guide groove 53; thereby, the injection slurry is quickly cooled and shaped, which effectively improves the processing efficiency; and when the injection molding cooling is completed, when the upper mold 32 is reset upward, under the rebound action of the first spring 552, the pressure plate 52 will be reset upward, thereby releasing the squeezing effect on the coolant in the isolation sleeve 511, and the coolant in the liquid storage tank 51 is liquid. The surface will be lowered, and the coolant entering the water-cooling tank 5 will flow back to the liquid storage tank 51, so that the coolant that absorbs heat will mix with the original coolant, thereby reducing the temperature of the coolant in the water-cooling tank 5, ensuring the cooling effect of the subsequent coolant, and improving the cooling efficiency; and when the gas in the piston cylinder 64 is pressurized and enters the gas collecting tank 65, under the thrust of the airflow, it will drive the pneumatic impeller 652 to rotate. At this time, the linkage shaft 651 is used to drive the stirring impeller 653 in the water-cooling tank 5 to rotate, so as to stir the coolant filled in the water-cooling tank 5, so that the coolants can exchange heat evenly, ensuring that the coolant can achieve a uniform cooling effect and improving the cooling quality.

[0040] Reference Figure 4-Figure 7, wherein the back-blowing assembly includes a back-blowing tube 6, which is fixed in the lower mold 21, and four groups of back-blowing tubes 6 are symmetrically arranged, a blocking rod 61 is slidably connected in the back-blowing tube 6, and the inner cavity of the blocking rod 61 is communicated with the inner cavity of the back-blowing tube 6, a pressure relief rod 62 is slidably connected in the blocking rod 61, and the bottom ends of the four groups of pressure relief rods 62 pass through the bottom of the work station disk 2 and are fixedly connected with an upper magnetic plate 63, a second spring 631 is fixedly connected between the top of the upper magnetic plate 63 and the bottom of the work station disk 2, and a positioning plate 621 is fixedly connected to the outer wall of the pressure relief rod 62; the tops of the work stations 2 on both sides of the lower mold 21 are fixedly connected with piston cylinders 64, a piston plate 641 is slidably connected in the piston cylinder 64, a third spring 642 is fixedly connected between the bottom of the piston plate 641 and the inner wall of the piston cylinder 64, an air collecting groove 65 is provided in the work station disk 2, and the piston cylinder 64 is connected to the inner cavity of the air collecting groove 65 The air collecting groove 65 is connected with the inner cavity of the backblowing pipe 6, and a one-way valve is arranged at the connection point. The two sides of the upper mold 32 are fixedly connected with the air pressure plate 321, and the air pressure plate 321 is aligned with the piston plate 641. The bottom of the piston cylinder 64 is provided with an air supply groove 643, and the bottom end of the air supply groove 643 is connected with the inner cavity of the processing table 1, and a one-way valve is arranged in the air supply groove 643; the bottom of the work station 2 is fixedly connected with the limit plate 22, and the bottom of the limit plate 22 slides in contact with the bottom of the inner cavity of the processing table 1, and the bottom of the inner cavity of the processing table 1 is fixedly connected with a servo motor 7, and the side wall of the output shaft of the servo motor 7 is fixedly connected with a driving gear 71, and the limit plate 22 is fixedly connected with a double-sided toothed disc 221, and the driving gear 71 is meshed with the double-sided toothed disc 221, and the top of the servo motor 7 is fixedly connected with a lower magnetic plate 72, and the lower magnetic plate 72 and the upper magnetic plate 63 are magnetically attracted to each other.

[0041] It should be noted that the second spring 631 is initially in a stretched state. When the positioning plate 621 is in contact with the bottom of the work station 2, the top of the pressure relief rod 62 is flush with the surface of the lower mold 21. The one-way valve at the connection between the gas collecting groove 65 and the backblowing pipe 6 can only allow the gas in the gas collecting groove 65 to enter the backblowing pipe 6. The one-way valve in the air replenishing groove 643 can only allow the gas in the processing table 1 to be sucked into the piston cylinder 64.

[0042] Through the arrangement of the above structure, when the injection molding and preliminary cooling are completed, the hydraulic cylinder 3 drives the upper mold 32 to reset upward. At this time, the servo motor 7 is turned on to drive the workstation disk 2 to rotate one workstation. In this process, the lower mold 21 with the foam packaging box will pass over the top of the servo motor 7. At this time, under the attraction of the lower magnetic plate 72 and the upper magnetic plate 63, the upper magnetic plate 63 will be pulled downward, thereby pulling the pressure relief rod 62 downward, so that the pressure relief rod 62 slides into the inner cavity of the blocking rod 61, thereby releasing the blockage of the output end of the blocking rod 61. At this time, the gas filled in the backblowing tube 6 will be discharged upward along the output end of the blocking rod 61, thereby applying an upward thrust to the foam packaging box on the lower mold 21, thereby removing the foam packaging box after preliminary cooling. Demolding is performed between the box and the lower mold 21 to avoid adhesion between the foam packaging box and the lower mold 21, thereby ensuring the production quality of the foam packaging box and improving processing efficiency; in addition, when the upper mold 32 is reset up and down, under the rebound action of the third spring 642, the piston plate 641 is pushed upward, thereby generating negative pressure suction in the piston cylinder 64, thereby opening the one-way valve in the air replenishing groove 643, so that the gas in the processing table 1 is sucked into the piston cylinder 64, thereby replenishing the gas in the piston cylinder 64 for back-blowing and demoulding, and at the same time driving the external air flow to continuously move into the processing table 1, thereby reducing the heat generated by the operation of the servo motor 7 in the processing table 1 and the meshing friction between the driving gear 71 and the double-sided gear disk 221, thereby improving the protection effect of the equipment.

[0043] Reference Figure 6 , Figure 7 Among them, both sides of the inner cavity of the air collecting groove 65 are rotatably connected with a linkage shaft 651, the outer wall of the linkage shaft 651 is fixedly connected with a pneumatic impeller 652, the top of the linkage shaft 651 penetrates into the water cooling groove 5 and is fixedly connected with a liquid stirring impeller 653, and the connecting port between the piston cylinder 64 and the air collecting groove 65 is opposite to the pneumatic impeller 652.

[0044] Through the arrangement of the above structure, when the gas in the piston cylinder 64 is pressurized into the gas collecting groove 65, the pneumatic impeller 652 will be driven to rotate under the thrust of the airflow. At this time, the linkage shaft 651 is used to drive the liquid stirring impeller 653 in the water cooling groove 5 to rotate, so as to stir the coolant filled in the water cooling groove 5, so that the coolant can exchange heat evenly, ensuring that the coolant can achieve a uniform cooling effect and improving the cooling quality.

[0045] Reference Figure 4 , Figure 8, wherein a stirring paddle 41 is rotatably connected in the injection molding tank 4, the rotating shaft of the stirring paddle 41 extends downward to the top of the processing table 1 and is rotatably connected thereto, a driven gear 42 is fixedly connected to the lower part of the rotating shaft side wall of the stirring paddle 41, a linkage groove 43 is provided on the side wall of the processing table 1, a linkage gear 431 is rotatably connected in the linkage groove 43, the linkage gear 431 is meshingly connected to the driven gear 42, and the linkage gear 431 is meshingly connected to the double-sided toothed disc 221; the top of the inner cavity of the injection molding tank 4 is arranged as a slope, the inclined lower end of the slope faces the input end of the discharge pipe of the injection molding tank 4, and a quantitative solenoid valve is arranged on the discharge pipe of the injection molding tank 4.

[0046] Through the arrangement of the above-mentioned structure, each time the workstation disc 2 rotates, the meshing transmission effect of the linkage gear 431, the double-sided gear disc 221 and the driven gear 42 will drive the stirring paddle 41 to rotate in the injection tank 4, thereby stirring the recycled slurry in the injection tank 4, so that the recycled slurries are mixed with each other, thereby improving the uniformity of the slurry dispersion and ensuring the production quality of the recycled foam packaging box.

[0047] Embodiment 2:

[0048] Reference Figure 1-Figure 8 , which is basically the same as the first embodiment, on the basis of the first embodiment, a foam packaging box processing method is proposed, and the steps are as follows:

[0049] Step 1: Clamp the upper mold 32 and the lower mold 21 to form an injection cavity and perform injection molding;

[0050] Step 2: Cooling the material in the injection molding cavity;

[0051] Step 3, demoulding the cooled foam packaging box from the lower mold 21;

[0052] Step 4: Rotate the work station disk 2 to switch the work station.

[0053] Reference Figure 1-Figure 8In the present invention, when in use, firstly, the hot-melted recycled slurry is added into the injection molding tank 4, then the servo motor 7 is turned on, and the work station plate 2 is driven to rotate by the meshing relationship between the driving gear 71 and the double-sided toothed disc 221, so that the lower mold 21 moves to the right below the upper mold 32 and then stops. At this time, the hydraulic cylinder 3 drives the mounting plate 31 to move downward, so that the upper mold 32 is sleeved on the lower mold 21, and in the above process, the air pressure plate 321 will squeeze the piston plate 641, so that the piston plate 641 compresses the third spring 6 After that, it slides downward to squeeze the gas in the piston cylinder 64, thereby opening the gas collecting groove 65 and the one-way valve in the back-blowing tube 6, allowing the gas to enter the back-blowing tube 6 and push the blocking rod 61 to slide upward, and finally the top of the blocking rod 61 is flush with the surface of the lower mold 21, and the top of the back-blowing tube 6 is blocked to form a sealed injection cavity; then the quantitative solenoid valve on the discharge pipe of the injection molding tank 4 is opened, so that a quantitative amount of slurry enters the injection cavity along the discharge pipe, thereby completing the injection molding of the foam packaging box.

[0054] When the upper mold 32 moves downward, the pressing plate 54 will squeeze the liquid pressing plate 52, so that the liquid pressing plate 52 slides downward along the isolation sleeve 511, thereby squeezing the coolant in the isolation sleeve 511, so that the coolant level in the liquid storage tank 51 rises and enters the water cooling tank 5 along the liquid guide groove 53; thereby, the injection slurry is quickly cooled and shaped, which effectively improves the processing efficiency; and when the injection molding cooling is completed, when the upper mold 32 is reset upward, under the rebound action of the first spring 552, the liquid pressing plate 52 will be reset upward, thereby releasing the squeezing effect on the coolant in the isolation sleeve 511, and the coolant level in the liquid storage tank 51 will be lowered. The coolant entering the water-cooling tank 5 will flow back into the liquid storage tank 51, so that the coolant that absorbs heat will mix with the original coolant, thereby reducing the temperature of the coolant in the water-cooling tank 5, ensuring the cooling effect of the subsequent coolant and improving the cooling efficiency; and when the gas in the piston cylinder 64 is pressurized and enters the gas collecting tank 65, the pneumatic impeller 652 will be driven to rotate under the thrust of the airflow. At this time, the linkage shaft 651 is used to drive the liquid stirring impeller 653 in the water-cooling tank 5 to rotate, so as to stir the coolant filled in the water-cooling tank 5, so that the coolants can exchange heat evenly, ensuring that the coolants can achieve a uniform cooling effect and improving the cooling quality;

[0055] When the injection molding and preliminary cooling are completed, the hydraulic cylinder 3 drives the upper mold 32 to reset upward. At this time, the servo motor 7 is turned on to drive the workstation 2 to rotate one station. In this process, the lower mold 21 with the foam packaging box will pass over the top of the servo motor 7. At this time, under the attraction between the lower magnetic plate 72 and the upper magnetic plate 63, the upper magnetic plate 63 will be pulled downward, thereby pulling the pressure relief rod 62 downward, so that the pressure relief rod 62 slides into the inner cavity of the blocking rod 61, thereby releasing the blockage of the output end of the blocking rod 61. At this time, the gas filled in the backblowing tube 6 will be discharged upward along the output end of the blocking rod 61, thereby exerting an upward pressure on the foam packaging box on the lower mold 21. The thrust effect is used to demould the foam packaging box and the lower mold 21 after preliminary cooling, so as to avoid adhesion between the foam packaging box and the lower mold 21, ensure the production quality of the foam packaging box, and improve the processing efficiency. Then, when the lower mold 21 is rotated to another station, it is removed by a robot arm or manually to complete the entire processing step; and each time the station disk 2 rotates, the meshing transmission effect of the linkage gear 431, the double-sided gear disk 221 and the driven gear 42 will drive the stirring paddle 41 to rotate in the injection tank 4, so as to stir the slurry in the injection tank 4, improve the uniformity of the slurry dispersion, and ensure the production quality of the foam packaging box.
