Description

Technical Field

[0001] The invention relates to the technical field of injection molding, and in particular to an injection molding device used for producing fast food boxes. Background Art

[0002] Disposable lunch boxes made of plastic are mainly polypropylene and polystyrene. Both are non-toxic, tasteless and odorless. Polypropylene is softer. The general operating temperature of polypropylene is -6 degrees to +120 degrees, so it is particularly suitable for holding hot meals and hot dishes. It can be heated in a microwave oven or even steamed in a steam cabinet. The operating temperature of modified polypropylene can be controlled at -18 degrees to +110 degrees. In addition to being heated to 100 degrees, the lunch boxes made of this polypropylene can also be refrigerated in the refrigerator. The production of fast food boxes is an industrial process involving multiple links. Polypropylene has the advantages of heat resistance, good chemical resistance, and recyclability. It is a common raw material for fast food boxes. There is also polystyrene. The plastic raw material is heated to a molten state, and then the melt is injected into a closed mold cavity through the screw or plunger of the injection molding machine. After cooling and solidification, it forms the shape of a fast food box.

[0003] In the prior art, after the fast food box is produced using an injection molding machine, the fast food box is embedded in the injection mold, and the common demoulding means is to use a suction cup or a mechanical clamp, but these means have a small contact surface with the fast food box, and the surface temperature of the fast food box is high after production. Therefore, the fast food box will be flexible. At this time, unloading will cause the fast food box to bend or deform, which will affect the production quality of the fast food box. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an injection molding device for fast food box production to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: An injection molding device for the production of fast food boxes, including an injection molding machine body. Two support frames are fixedly installed on the top surface of the injection molding machine body, and a moving table is arranged on the top surfaces of the two support frames; a blanking component, which is arranged on the bottom surface of the moving table and is used for blanking the fast food boxes produced by injection molding. The blanking component includes: a mounting frame, which is arranged on the bottom surface of the moving table. An adsorption shell is arranged inside the mounting frame. A number of ventilation holes are opened on one side of the adsorption shell. A number of sponge blocks are fixedly installed on one side of the adsorption shell. A number of ventilation holes are opened on one side of the sponge block, and the ventilation holes are communicated with the ventilation holes. A fixing plate is fixedly installed on one side of the adsorption shell. An air inlet hole is opened on one side of the fixing plate. A negative pressure pump is fixedly installed on the top surface of the moving table. A hose is fixedly sleeved on the outer wall surface of the negative pressure port of the negative pressure pump, and the hose is fixedly sleeved with the air inlet hole; a spraying component for spraying a release agent on the sponge block is arranged inside the mounting frame; a displacement component for moving the moving table is arranged on one side of the support frame.

[0006] By adopting the above technical solution, through the arranged adsorption shell, after the staff uses the injection molding machine body to inject and manufacture the fast food boxes, when the two molds are separated, the mounting frame drives the adsorption shell to move downward, so that the adsorption shell is located between the two injection molds. At this time, the adsorption shell is made to approach and contact the fast food box in the mold. At this time, the staff uses the negative pressure pump. The suction force generated after the negative pressure pump operates will enter the inside of the adsorption shell through the hose, and then be transmitted to the surface of the adsorption shell through a number of ventilation holes, so as to facilitate the adsorption of the fast food box for demolding and blanking. When the adsorption shell approaches the fast food box, the sponge block will first contact the surface of the fast food box. Then, the suction force generated by the negative pressure pump will pass through the ventilation holes and reach the surface of the sponge block through the ventilation holes, so that the fast food box can be adsorbed on the surface of the sponge block. By the large-area contact of the sponge block with the fast food box for adsorption, it can prevent the blanking methods such as suction cups, where the contact area with the fast food box is small and causes the fast food box to deform. At the same time, by the contact of the sponge block with the fast food box, it can prevent the hard structure from scratching the fast food box during blanking and affecting the product quality.

[0007] Preferably, the spraying assembly includes: a storage tank fixedly installed inside the mounting frame; a fixed frame fixedly installed on one side of the mounting frame; a water pump fixedly installed on the top surface of the fixed frame; a water outlet hole formed on one side of the storage tank; the water inlet of the water pump is fixedly sleeved with the water outlet hole; a shunt pipe fixedly installed inside the storage tank; a number of limiting holes are respectively formed on the outer circumferential wall of the shunt pipe and one side of the storage tank; a fixed pipe is fixedly sleeved on the inner circumferential wall of the limiting hole; an atomizing nozzle is fixedly sleeved on the inner circumferential wall of the fixed pipe; a water inlet hole is formed on the outer circumferential wall of the shunt pipe; a connecting pipe is fixedly sleeved on the inner circumferential wall of the water inlet hole; and the connecting pipe passes through the storage tank and is fixedly sleeved with the water outlet of the water pump.

[0008] By adopting the above technical solution, through the provided storage tank, the staff puts the food-grade antistatic release agent inside the storage tank. Before demolding the fast food box, by using the water pump, the water pump will extract the food-grade antistatic release agent inside the storage tank and discharge it into the shunt pipe through the connecting pipe, and then shunt it into the inside of a number of fixed pipes. Subsequently, the food-grade antistatic release agent will be atomized and sprayed on the surface of the adsorption shell and the sponge block, thereby preventing the fast food box from generating static electricity and sticking to the sponge block. At the same time, by spraying the food-grade antistatic release agent, the fast food box can be cooled down, preventing the fast food box with incomplete cooling from being sticky and sticking to the demolding and blanking structure.

[0009] Preferably, the displacement assembly includes: two mounting columns respectively fixedly installed on one side of the two support frames; a rotating column fixedly installed on the top surface of the mounting column; a stepping motor fixedly installed on the bottom surface of the mounting column; a synchronous pulley is respectively arranged on the top surface of the driving shaft of the stepping motor and the outer circumferential wall of the rotating column; the synchronous pulley is movably sleeved with the rotating column; a synchronous belt is wound around the outer circumferential walls of the two synchronous pulleys; a number of fixing grooves are formed on the bottom surface of the moving table; and the fixing grooves are fixedly sleeved with the synchronous belt.

[0010] By adopting the above technical solution, through the provided synchronous belt, the staff uses the stepping motor. The rotation of the driving shaft of the stepping motor will drive the synchronous pulley to rotate. Furthermore, the rotation of the synchronous pulley will cause the synchronous belt to rotate around the two synchronous pulleys. At this time, the synchronous belt will pull the moving table to move during movement, thereby facilitating the movement of the moving table, the mounting frame and the adsorption shell, and displacing the adsorption shell to the demolding position.

[0011] Preferably, a mounting hole is formed on the top surface of the moving table; an electric hydraulic rod is fixedly sleeved on the inner circumferential wall of the mounting hole; and the bottom surface of the telescopic rod of the electric hydraulic rod is fixedly installed with the mounting frame.

[0012] By adopting the above technical solution, through the provided electric hydraulic rod, when the staff uses the electric hydraulic rod, the telescopic rod of the electric hydraulic rod moves downward, which will push the mounting frame to drive the adsorption shell to move downward, so as to facilitate lowering the position of the adsorption shell between the two injection molds for demolding and blanking of the fast food boxes.

[0013] Preferably, two limit blocks are fixedly installed on the bottom surface of the moving table, and a guide rail is fixedly installed on the top surface of the mounting column. The limit blocks are slidably connected to the guide rail.

[0014] By adopting the above technical solution, through the provided guide rail, when the moving table moves, it will drive the limit blocks to move on the guide rail, so as to facilitate supporting and limiting the moving table.

[0015] Preferably, rotation holes are respectively formed on both sides of the mounting frame, rotating columns are respectively fixedly installed on both sides of the adsorption shell, the rotating columns are movably sleeved in the rotation holes, and a servo motor is fixedly installed on one side of the mounting frame. The driving shaft of the servo motor is fixedly installed with the rotating column.

[0016] By adopting the above technical solution, through the provided rotating column, after the fast food box is adsorbed on the surface of the sponge block, by using the servo motor, the rotation of the driving shaft of the servo motor will drive the rotating column, the adsorption shell and the sponge block to rotate, and then rotate the sponge block and the fast food box to the downward position, so as to facilitate the fast food box to fall from the surface of the sponge block and prevent the fast food boxes from colliding with each other and causing scratches when falling in the upright state.

[0017] Preferably, a water injection hole is formed on the top surface of the storage tank, and a sealing block is movably clamped inside the water injection hole.

[0018] By adopting the above technical solution, through the provided water injection hole, food-grade antistatic demolding agent is added to the inside of the storage tank.

[0019] Preferably, a slideway is fixedly installed on the top surface of the injection molding machine body, and a plurality of cooling pipes are fixedly installed on the inner bottom surface of the slideway.

[0020] By adopting the above technical solution, through the provided cooling pipes, by injecting cold water into the cooling pipes, when the adsorption shell moves to the top surface of the slideway and the fast food box falls, the fast food box will fall into the inside of the slideway and slide down through the inclined surface of the slideway. During this process, the fast food box will contact the cooling pipes, so as to facilitate cooling and eliminating the residual temperature of the fast food box, making it harden quickly and preventing the fast food box from remaining in a soft state due to the residual temperature, resulting in bending during subsequent stacking of the fast food boxes.

[0021] In summary, the present invention mainly has the following beneficial effects: By using the injection molding machine body, support frame, moving table, mounting frame, adsorption shell, fixing plate, negative pressure pump, hose and sponge block arranged in cooperation, the fast food box can be adsorbed on the surface of the sponge block. The large area of the sponge block is close to the fast food box for adsorption, which can prevent the blanking methods such as suction cups from causing deformation of the fast food box due to the small contact area with the fast food box. At the same time, by making the sponge block contact with the fast food box, it can prevent the hard structure from scratching the fast food box during blanking, affecting the product quality.

By providing the synchronous belt 27, the staff uses the stepping motor 25. The rotation of the driving shaft of the stepping motor 25 will drive the synchronous pulley 26 to rotate.

[0028] Example 4: Based on the above Examples 1, 2 or 3, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10, rotation holes 33 are respectively formed on both sides of the mounting frame 4, rotating columns 34 are respectively fixedly installed on both sides of the adsorption shell 5, the rotating columns 34 are movably sleeved with the rotation holes 33, a servo motor 35 is fixedly installed on one side of the mounting frame 4, and the driving shaft of the servo motor 35 is fixedly installed with the rotating column 34. By providing the rotating column 34, after the fast food box is adsorbed on the surface of the sponge block 11, by using the servo motor 35, the rotation of the driving shaft of the servo motor 35 will drive the rotating column 34, the adsorption shell 5 and the sponge block 11 to rotate, so as to rotate the sponge block 11 and the fast food box to the downward position, thereby facilitating the falling of the fast food box from the surface of the sponge block 11 and preventing the fast food boxes from colliding with each other when falling in the upright state and causing scratches. A water injection hole 36 is formed on the top surface of the storage tank 13, a sealing block 37 is movably clamped inside the water injection hole 36, a slideway 38 is fixedly installed on the top surface of the injection molding machine body 1, and a plurality of cooling pipes 39 are fixedly installed on the inner bottom surface of the slideway 38. By providing the cooling pipes 39, by injecting cold water into the cooling pipes 39, when the adsorption shell 5 moves to the top surface of the slideway 38, the fast food box is allowed to fall, and then the fast food box will fall into the slideway 38 and slide down through the inclined surface of the slideway 38. During this process, the fast food box will contact the cooling pipes 39, thereby facilitating the cooling and elimination of the residual temperature of the fast food box, making it quickly hardened and preventing the residual temperature of the fast food box from keeping the fast food box in a soft state all the time, resulting in bending of the fast food box during subsequent stacking of materials.

[0029] Working principle: Please refer to Figures 1 - 10 As shown, by providing the adsorption shell 5, after the staff uses the injection molding machine body 1 to inject and manufacture the fast food box, after the two molds are separated, by driving the adsorption shell 5 to move downward by the mounting frame 4, the adsorption shell 5 is located between the two injection molds. At the same time, the adsorption shell 5 is brought close to the fast food box in the mold and contacts it. At this time, the staff uses the negative pressure pump 9. The suction force generated after the operation of the negative pressure pump 9 will enter the interior of the adsorption shell 5 through the hose 10, and then be transmitted to the surface of the adsorption shell 5 through a plurality of ventilation holes 6, so as to facilitate the adsorption of the fast food box for demolding and blanking. When the adsorption shell 5 approaches the fast food box, the sponge block 11 will first contact the surface of the fast food box. Then, the suction force generated by the negative pressure pump 9 will pass through the ventilation holes 6 and reach the surface of the sponge block 11 through the ventilation holes 12, so that the fast food box can be adsorbed on the surface of the sponge block 11. By adsorbing the fast food box with the large area of the sponge block 11 in contact with it, it is possible to prevent the blanking method such as the suction cup, where the contact area with the fast food box is small and the fast food box is deformed. At the same time, by making the sponge block 11 contact the fast food box, it is possible to prevent the hard structure from scratching the fast food box during the blanking of the fast food box and affecting the product quality.

[0030] Through the provided storage box 13, the staff puts food-grade antistatic release agent inside the storage box 13. Before demolding the fast food box, by using the water pump 15, the water pump 15 will extract the food-grade antistatic release agent inside the storage box 13 and discharge it into the inside of the shunt pipe 17 through the connecting pipe 22, and then shunt into the inside of several fixed pipes 19. Subsequently, the food-grade antistatic release agent will be atomized and sprayed on the surfaces of the adsorption shell 5 and the sponge block 11 through the atomizing nozzle 20, so as to prevent the fast food box from generating static electricity and sticking to the sponge block 11. At the same time, the fast food box can be cooled by spraying the food-grade antistatic release agent, preventing the fast food box with incomplete cooling from having stickiness and sticking to the demolding and blanking structure.

[0031] Through the provided synchronous belt 27, the staff uses the stepping motor 25. The rotation of the drive shaft of the stepping motor 25 will drive the synchronous wheel 26 to rotate. Furthermore, the rotation of the synchronous wheel 26 will cause the synchronous belt 27 to rotate around the two synchronous wheels 26. At this time, the synchronous belt 27 will pull the moving table 3 to move during the movement, so as to facilitate the movement of the moving table 3, the mounting bracket 4 and the adsorption shell 5, and displace the adsorption shell 5 to the demolding position.

[0032] Through the provided rotating column 34, after the fast food box is adsorbed on the surface of the sponge block 11, by using the servo motor 35, the rotation of the drive shaft of the servo motor 35 will drive the rotating column 34, the adsorption shell 5 and the sponge block 11 to rotate, and then rotate the sponge block 11 and the fast food box to the downward position, so as to facilitate the fast food box to fall from the surface of the sponge block 11 and prevent the fast food boxes from hitting each other and causing scratches when falling in the upright state.

[0033] Through the provided cooling pipe 39, by injecting cold water into the inside of the cooling pipe 39, when the adsorption shell 5 moves to the top surface of the slideway 38, let the fast food box fall. Then the fast food box will fall into the inside of the slideway 38 and slide down through the inclined surface of the slideway 38. During this process, the fast food box will contact the cooling pipe 39, so as to facilitate the cooling and elimination of the remaining temperature of the fast food box, make it harden quickly, and prevent the remaining temperature of the fast food box from keeping the fast food box in a soft state all the time, resulting in bending of the fast food box during subsequent stacking.
