Description

Technical Field

[0001] The present invention relates to the technical field of forming machines, and more particularly to a full-automatic foam packaging product forming machine. Background Art

[0002] Foam packaging products are packaging products made of foam materials, which are widely used to protect the safety of items during transportation and storage. The main function of this type of packaging material is to provide a cushioning effect to absorb vibration and impact and prevent the items in the package from being damaged by external forces. The production process of foam packaging products can be roughly divided into the following steps: first, prepare the raw materials, then pre-foam the raw materials, the pre-foamed raw materials need to be matured, and finally the raw materials are loaded into the mold of the fully automatic molding machine through a screw conveyor, and the raw materials are heated by steam to expand and shape the raw materials in the mold.

[0003] Different types of foam packaging products have different physical performance requirements. For example, for packaging that needs to withstand greater pressure or weight, such as heavy machinery and household appliances, raw materials with higher density and greater compressive strength will be selected; for packaging of precision instruments or fragile items, more attention is paid to the cushioning effect of the material. At this time, 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 reduce 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 delivery of raw materials to the mold through a screw conveyor, a connecting pipe is set between the output end of the screw conveyor and the mold in the prior art. The setting of the connecting pipe facilitates the delivery of raw materials to the mold when changing different molds.

[0004] However, since different foam products use different raw materials, some raw materials will remain in the connecting tube after the molding mold is replaced, resulting in the specifications and quality of the first foam product not meeting the processing requirements, resulting in a waste of raw materials and unsatisfactory use effects.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Refer to the instruction manual Figures 1 to 5 A fully automatic foam packaging product forming machine comprises a support frame 1, a forming mechanism 2 is arranged on the support frame 1, the forming mechanism 2 comprises a fixed mold 21 and a movable mold 22, the fixed mold 21 and the movable mold 22 are adapted, 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; A feeding mechanism 4 is provided on the support frame 1. The feeding mechanism 4 includes a conveying cylinder 41. A screw conveyor 44 is rotatably provided in the conveying cylinder 41. The screw conveyor 44 conveys the raw materials by rotating. A discharge mechanism 5 is provided between the conveying cylinder 41 and the fixed mold 21 . The discharge mechanism 5 includes two connecting pipes 52 . 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 .

[0027] It should be noted that a feed hole 1 is opened on the fixed mold 21, and a gate valve is fixedly installed in the feed hole 1. The gate valve is used to connect or close the fixed mold 21 with the outside. A support plate is fixedly installed on the support frame 1, and the feed end of the gate valve extends into the support plate.

[0028] The specific implementation scenario is as follows: first, the movable mold 22 is driven to close the mold with the fixed mold 21, and then the raw material is placed in the conveying cylinder 41, and the conveying cylinder 41 is driven to rotate so that the raw material is conveyed along the length direction of the conveying cylinder 41, and the raw material enters the cavity between the fixed mold 21 and the movable mold 22 through the baffle 54. When the raw material is conveyed, the feed hole 1 can be blocked, and steam is introduced into the raw material between the fixed mold 21 and the movable mold 22. After being subjected to high temperature, the raw material expands and takes shape 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, some raw materials will remain in the connecting tube 52 at this time, and the connecting tube 52 is driven to rotate. Figure 5 The left end of the connecting pipe 52 rotates against the end of the conveying cylinder 41, and the right end of the connecting pipe 52 rotates against the supporting plate, and then the empty connecting pipe 52 is rotated between the conveying cylinder 41 and the fixed mold 21, so that the conveying cylinder 41 and the fixed mold 21 are connected through the empty connecting pipe 52. Compared with the prior art, the residual raw materials in the equipment can be completely discharged, and the waste of raw materials can be avoided after the mold is replaced, so as to ensure that the processed foam packaging meets the design requirements.

[0029] Refer to the instruction manual Figure 5 In order to prevent the raw materials in the connecting tube 52 from leaking out, specifically, the discharging mechanism 5 includes a second rotary driver 51, which is fixedly arranged on the conveying cylinder 41, and a fixing frame is fixedly arranged on the output shaft of the second rotary driver 51, and the two connecting tubes 52 are fixedly arranged on the fixing frame, and the two ends of the connecting tube 52 are respectively slidably arranged with the conveying cylinder 41 and the fixed mold 21. The discharging mechanism 5 also includes a first linear driver 53, which is fixedly arranged on the connecting tube 52, and a baffle 54 is fixedly arranged on the output shaft of the first linear driver 53, and the baffle 54 is adapted to the end of the connecting tube 52.

[0030] It should be noted that the linear drive 1 53 is configured 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 that the material discharged from the conveying cylinder 41 will not leak through the sliding space of the conveying cylinder 41. The rotary drive 2 51 is configured as a motor, and the output shaft of the motor is fixedly arranged on the fixed frame.

[0031] It should also be noted that when it is necessary to install an empty connecting tube 52 between the conveying cylinder 41 and the fixed mold 21, the linear driver 1 53 is started, and the movement of the output shaft of the linear driver 1 53 drives the screw conveyor 44 to block the connecting tube 52, and the rotary driver 2 51 is started, and the rotation of the output shaft of the rotary driver 2 51 drives the fixed frame to rotate to adjust the position of the connecting tube 52. Since the left end of the connecting tube 52 is blocked by the baffle 54, the raw material can be prevented from leaking from the connecting tube 52.

[0032] Refer to the instruction manual Figure 6 In order to further improve the utilization of raw materials and avoid wasting the residual materials in the connecting pipe 52, specifically, a pushing mechanism 6 is provided on the conveying cylinder 41, and the pushing mechanism 6 includes a linear drive 2 61. A pushing plate 62 is fixedly provided on the output shaft of the linear drive 2 61, and the pushing plate 62 is adapted to the inner wall of the connecting pipe 52.

[0033] It should be noted that a second feed hole is provided on the fixed mold 21 , a gate valve is fixedly provided in the second feed hole, and the right end of the connecting pipe 52 is adapted to the gate valve.

[0034] 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 to the cavity between the fixed mold 21 and the movable mold 22, some raw materials remain in the connecting pipe 52. First, the linear drive 1 53 is started to make the baffle 54 block the end of the connecting pipe 52, close the gate valve in the feed hole 1, and then the rotary drive 2 51 is started. The output shaft of the rotary drive 2 51 is rotated to adjust the position of the connecting pipe 52. When the right end of the connecting pipe 52 containing the raw materials is aligned with the feed hole 2, the connecting pipe 52 is moved to the right end of the connecting pipe 52. After the gate valves are aligned, the gate valve in the second feed hole is opened, and the linear driver 2 61 is started. The output shaft of the linear driver 2 61 drives the push plate 62 to move to the right, and then the linear driver 1 53 is started so that the baffle 54 no longer blocks 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 cavities of the fixed mold 21 and the movable mold 22, and then the gate valve in the second feed hole is closed, and then the output shaft of the linear driver 2 61 is driven to move in the opposite direction, so that the raw materials are fully utilized to avoid waste and reduce the workload of the staff.

[0035] Refer to the instruction manual Figures 1 to 3 In order to facilitate the mold closing and demolding of the fixed mold 21 and the movable mold 22, the driving mechanism 3 further includes two threaded rods 31, which are both rotatably arranged on the support frame 1, and the threaded rods 31 are threadedly connected with the movable mold 22. A transmission wheel 32 is fixedly arranged on the threaded rod 31, and the two transmission wheels 32 are connected through the same conveyor belt transmission. Two guide rails 33 are fixedly arranged on the support frame 1, and a guide seat is fixedly arranged on the movable mold 22, and the guide seat is slidably arranged on the guide rails 33.

[0036] It should be noted that a motor is fixedly installed on the support frame 1, and the output shaft of the motor is fixedly installed on the transmission wheel 32. When the motor is started, the rotation of the motor output shaft drives the transmission wheel 32 to rotate, and the transmission belt of the transmission wheel 32 causes the two threaded rods 31 to rotate synchronously, thereby achieving the effect of driving the movable mold 22 to move horizontally. By setting the guide rail 33 and the guide seat, the horizontal movement of the movable mold 22 is smoother.

[0037] Refer to the instruction manual Figures 1 to 5 In order to facilitate preheating of the cut material and improve the efficiency of steam expansion of the raw material, specifically, a heater and a heat preservation layer 411 are fixedly arranged on the conveying cylinder 41, and 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 material in the conveying cylinder 41, and the heat preservation layer 411 is used to keep the conveying cylinder 41 warm. The feeding mechanism 4 also includes a rotating driver 43, which is fixedly arranged on the support frame 1, and the output shaft of the rotating driver 43 is fixedly arranged with the screw conveyor 44, and the conveying cylinder 41 is fixedly connected with a feed hopper 42.

[0038] It should be noted that the heater is an electric heater, and the insulation layer 411 includes but is not limited to polyurethane foam. The rotary driver 43 is a motor, and the output shaft of the motor is fixedly arranged with the screw conveyor 44, which is an auger conveyor.

[0039] It should also be noted that the raw materials enter the conveying cylinder 41 through the feed hopper 42, and the rotary driver 43 is started. The rotation of the output shaft of the rotary driver 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, thereby achieving the effect of conveying the raw materials.

[0040] Refer to the instruction manual Figures 1 to 3 In order to further optimize the processing technology, specifically, a suction hood is fixedly provided on the support frame 1, and the suction hood is located between the fixed mold 21 and the movable mold 22. The suction hood is fixedly connected with an exhaust pipe, and one end of the exhaust pipe away from the suction hood is fixedly connected with an exhaust fan. A clamping shaft is fixedly provided on the movable mold 22, and a clamping groove is provided on the fixed mold 21. The clamping shaft and the clamping groove are clamped together. The fixed mold 21 is provided with an air hole, and the air hole is used to fill steam between the fixed mold 21 and the movable mold 22.

[0041] 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, an air suction hood is set between the fixed mold 21 and the movable mold 22. When the foam product is formed, the movable mold 22 and the fixed mold 21 are demolded. The temperature of the foam product is high and waste gas is generated. The exhaust fan is started, and the exhaust fan draws the waste gas through the air suction hood and collects the waste gas. The waste gas is centrally processed, collected and purified before being discharged to avoid pollution to the environment.

[0042] It should also be noted that a steam hole is opened on the fixed mold 21, and an air inlet pipe is fixedly connected to the outside of the steam hole. The air inlet pipe is used to transport hot steam to the fixed mold 21 and the movable mold 22. The hot steam can expand the raw material, and the expanded raw material is shaped in the fixed mold 21 and the movable mold 22.

[0043] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
