Description

Technical Field

[0001] The present invention relates to the technical field of molding machines, and more specifically, to a fully automatic foam packaging product molding machine. Background Art

[0002] Foam packaging products are packaging products made of foam materials and are widely used to protect the safety of items during transportation and storage. The main function of such packaging materials is to provide buffering to absorb vibrations and impacts and prevent the items inside the packaging from being damaged by external forces. The manufacturing process of foam packaging products can generally be divided into: first, preparing the raw materials, then pre-foaming the raw materials. The pre-foamed raw materials need to undergo a ripening operation. Finally, the raw materials are loaded into the mold of a fully automatic molding machine through a screw conveyor, and the raw materials are heated by steam to expand and take shape in the mold.

[0003] For different types of foam packaging products, the physical property requirements are different. For example, for packaging that needs to bear greater pressure or weight, such as heavy machinery, household appliances, etc., raw materials with higher density and greater compressive strength will be selected; for the packaging of precision instruments or fragile items, more attention is paid to the buffering effect of the material, and in this case, raw materials with good elasticity and energy absorption characteristics will be selected. Therefore, different foam packaging products use raw materials of different specifications. In order to reduce production costs and the space occupied by equipment, the molds used in existing fully automatic molding machines can be disassembled and replaced according to usage requirements. In order to facilitate the transportation of raw materials to the mold through a screw conveyor, a connecting pipe is provided between the output end of the screw conveyor and the mold in the prior art. The setting of the connecting pipe facilitates the transportation of raw materials into the mold when replacing different molds.

[0004] However, since different raw materials are used for different foam products, after replacing the molding mold, some raw materials will remain in the connecting pipe, resulting in the inability to meet the processing requirements in terms of specifications and quality when processing the first foam product, causing waste of raw materials and less than ideal usage effects.

Detailed implementation mode

[0028] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation modes are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] Refer to the attached drawings of the specification Figures 1 to 5 , a fully automatic foam packaging product molding machine, including a support frame 1, a molding mechanism 2 is arranged on the support frame 1, the molding mechanism 2 includes a fixed mold 21 and a movable mold 22, the fixed mold 21 and the movable mold 22 are adapted to each other, the fixed mold 21 is fixedly arranged on the support frame 1, a driving mechanism 3 is arranged on the support frame 1, and the output end of the driving mechanism 3 is used to drive the movable mold 22 to move horizontally;

[0030] A feeding mechanism 4 is arranged on the support frame 1, the feeding mechanism 4 includes a conveying cylinder 41, a spiral conveyor 44 is rotatably arranged in the conveying cylinder 41, and the spiral conveyor 44 conveys raw materials through rotation;

[0031] A discharging mechanism 5 is arranged between the conveying cylinder 41 and the fixed mold 21, the discharging mechanism 5 includes two connecting pipes 52, and the output end of the conveying cylinder 41 is connected to the input end of the fixed mold 21 through the corresponding connecting pipes 52.

[0032] It should be noted that a first feeding hole is opened on the fixed mold 21, a gate valve is fixedly arranged in the first feeding hole, the gate valve is used to connect or close the fixed mold 21 with the outside, a support plate is fixedly arranged on the support frame 1, and the feeding end of the gate valve extends into the support plate.

[0033] The specific implementation scenario is as follows: First, drive the movable mold 22 to close with the fixed mold 21, then put the raw materials into the conveying cylinder 41, drive the conveying cylinder 41 to rotate to convey the raw materials along the length direction of the conveying cylinder 41, and the raw materials enter the cavity between the fixed mold 21 and the movable mold 22 through the baffle 54. When the raw material conveying is completed, the first feeding hole can be blocked, and steam is introduced into the raw materials between the fixed mold 21 and the movable mold 22. After being heated by high temperature, the raw materials expand and are shaped in the fixed mold 21 and the movable mold 22. When it is necessary to replace the fixed mold 21 and the movable mold 22 to process different types of foam products, at this time, some raw materials will remain in the connecting pipe 52. Drive the connecting pipe 52 to rotate, refer to Figure 5, the left end of the connecting pipe 52 rotates while being in contact with the end of the conveying cylinder 41, and the right end of the connecting pipe 52 rotates while being in contact with the support plate. Then, the empty connecting pipe 52 is rotated between the conveying cylinder 41 and the fixed mold 21, and the conveying cylinder 41 and the fixed mold 21 are connected through the empty connecting pipe 52. Compared with the prior art, it can completely discharge the raw materials remaining in the equipment, avoid waste of raw materials after changing the mold, and ensure that the processed foam packaging meets the design requirements.

[0034] Refer to the attached drawings of the specification Figure 5 , in order to prevent the raw materials in the connecting pipe 52 from leaking out. Specifically, the discharging mechanism 5 includes a second rotating driver 51. The second rotating driver 51 is fixedly arranged on the conveying cylinder 41. A fixing frame is fixedly arranged on the output shaft of the second rotating driver 51. Both connecting pipes 52 are fixedly arranged on the fixing frame. The two ends of the connecting pipe 52 are respectively slidably arranged with the conveying cylinder 41 and the fixed mold 21. The discharging mechanism 5 further includes a first linear driver 53. The first linear driver 53 is fixedly arranged on the connecting pipe 52. A baffle 54 is fixedly arranged on the output shaft of the first linear driver 53. The baffle 54 is adapted to the end of the connecting pipe 52.

[0035] It should be noted that the first linear driver 53 is set as a cylinder, and the baffle 54 is fixedly arranged on the output shaft of the cylinder. The thickness of the baffle 54 is set very thin, so the situation that the material discharged from the conveying cylinder 41 leaks out through the sliding space of the conveying cylinder 41 will not occur. The second rotating driver 51 is set as a motor, and the output shaft of the motor is fixedly arranged with the fixing frame.

[0036] It also should be noted that when it is necessary to install the empty connecting pipe 52 between the conveying cylinder 41 and the fixed mold 21, start the first linear driver 53. The movement of the output shaft of the first linear driver 53 drives the screw conveyor 44 to block the connecting pipe 52. Start the second rotating driver 51. The rotation of the output shaft of the second rotating driver 51 drives the fixing frame to rotate to adjust the position of the connecting pipe 52. Since the left end of the connecting pipe 52 is blocked by the baffle 54, it can prevent the raw materials from leaking out of the connecting pipe 52.

[0037] Refer to the attached drawings of the specification Figure 6 , in order to further improve the utilization of raw materials and avoid waste of the remaining materials in the connecting pipe 52. Specifically, a pushing mechanism 6 is arranged on the conveying cylinder 41. The pushing mechanism 6 includes a second linear driver 61. A push plate 62 is fixedly arranged on the output shaft of the second linear driver 61. The push plate 62 is adapted to the inner wall of the connecting pipe 52.

[0038] It should be noted that a second feeding hole is opened on the fixed mold 21, and a gate valve is fixedly arranged in the second feeding hole. The right end of the connecting pipe 52 is adapted to the gate valve.

[0039] It should also be noted that the screw conveyor 44 rotates to convey the raw materials in the conveying cylinder 41. After all the raw materials in the conveying cylinder 41 are conveyed into the cavity between the fixed mold 21 and the movable mold 22, there is some residual raw material in the connecting pipe 52. First, start the linear actuator 53 to make the baffle 54 block the end of the connecting pipe 52, and close the gate valve in the first feeding hole. Then, start the rotary actuator 51. The rotation of the output shaft of the rotary actuator 51 adjusts the position of the connecting pipe 52. When the right end of the connecting pipe 52 filled with raw materials aligns with the gate valve of the second feeding hole, open the gate valve in the second feeding hole, and start the linear actuator 61. The output shaft of the linear actuator 61 drives the push plate 62 to move to the right. Then, start the linear actuator 53 to make the baffle 54 no longer block the end of the connecting pipe 52. The push plate 62 extends into the connecting pipe 52 to push the remaining raw materials into the cavity between the fixed mold 21 and the movable mold 22, and then close the gate valve in the second feeding hole. Then, drive the output shaft of the linear actuator 61 to move in the reverse direction, making full use of the raw materials to avoid waste and reducing the workload of the staff.

[0040] Refer to the attached drawings of the specification Figures 1 to 3 For the convenience of clamping and demolding of the fixed mold 21 and the movable mold 22, specifically, the driving mechanism 3 further includes two threaded rods 31. Both of the two threaded rods 31 are rotatably arranged on the support frame 1. The threaded rods 31 are threadedly connected to the movable mold 22. A transmission wheel 32 is fixedly arranged on the threaded rod 31. The two transmission wheels 32 are connected by the same conveyor belt. Two guide rails 33 are fixedly arranged on the support frame 1. A guide seat is fixedly arranged on the movable mold 22. The guide seat is slidably arranged on the guide rail 33.

[0041] It should be noted that a motor is fixedly arranged on the support frame 1. The output shaft of the motor is fixedly arranged with the transmission wheel 32. Start the motor. The rotation of the output shaft of the motor drives the transmission wheel 32 to rotate. The transmission wheel 32 drives the belt to make the two threaded rods 31 rotate synchronously, achieving the effect of driving the horizontal movement of the movable mold 22. By arranging the guide rail 33 and the guide seat, the horizontal movement of the movable mold 22 is made more stable.

[0042] Refer to the attached drawings of the specification Figures 1 to 5 For the convenience of preheating the cut-off material and improving the efficiency of steam puffing of the raw materials, specifically, a heater and a heat preservation layer 411 are fixedly arranged on the conveying cylinder 41. The heater is located between the heat preservation layer 411 and the conveying cylinder 41. The heater is used to heat the conveying cylinder 41 to preheat the materials in the conveying cylinder 41. The heat preservation layer 411 is used to keep the temperature of the conveying cylinder 41. The feeding mechanism 4 further includes a rotary actuator 43. The rotary actuator 43 is fixedly arranged on the support frame 1. The output shaft of the rotary actuator 43 is fixedly arranged with the screw conveyor 44. The conveying cylinder 41 is fixedly communicated with a feed hopper 42.

[0043] It should be noted that an electric heater is selected as the heater, and the heat insulation layer 411 includes but is not limited to being set as polyurethane foam. The rotation drive 43 is set as a motor, and the output shaft of the motor is fixedly arranged with the screw conveyor 44, and the screw conveyor 44 is a auger conveyor.

[0044] It also should be noted that the raw materials enter the conveying cylinder 41 through the feed hopper 42. Start the rotation drive 43. The rotation of the output shaft of the rotation drive 43 drives the screw conveyor 44 to rotate, and the rotation of the screw conveyor 44 drives the raw materials to move along the length direction of the conveying cylinder 41, achieving the effect of conveying the raw materials.

[0045] Refer to the attached drawings of the specification Figures 1 to 3 In order to further optimize the processing technology, specifically, a suction hood is fixedly arranged on the support frame 1. The suction hood is located between the fixed mold 21 and the movable mold 22. An exhaust pipe is fixedly communicated with the suction hood, and one end of the exhaust pipe far away from the suction hood is fixedly communicated with a suction fan. A clamping shaft is fixedly arranged on the movable mold 22, a clamping groove is opened on the fixed mold 21, the clamping shaft is clamped with the clamping groove, and air holes are opened on the fixed mold 21 for filling steam between the fixed mold 21 and the movable mold 22.

[0046] It should be noted that harmful waste gas will be generated after the raw materials are heated by steam. If the harmful waste gas is directly discharged into the environment, it will cause environmental pollution. Therefore, a suction hood is arranged between the fixed mold 21 and the movable mold 22. When the foam product is formed and the movable mold 22 and the fixed mold 21 are demolded, the temperature of the foam product is relatively high and waste gas is generated. Start the suction fan. The suction fan extracts the waste gas through the suction hood and collects the waste gas. The waste gas is centrally processed, collected and purified before being discharged, so as to avoid polluting the environment.

[0047] It also should be noted that steam holes are opened on the fixed mold 21, and an air inlet pipe is fixedly communicated with the outside of the steam holes. The air inlet pipe is used to convey hot steam into the fixed mold 21 and the movable mold 22. The hot steam can make the raw materials expand, and the expanded raw materials are shaped in the fixed mold 21 and the movable mold 22.

[0048] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
