Description

Technical Field

[0001] This utility model relates to the field of hot pressing production technology, and in particular to a hot pressing production system. Background Technology

[0002] In the field of hot pressing composite molding, two blanks are typically used for hot pressing. Currently, most production equipment on the market mounts the die and punch on the pressure head and bearing platform of a hydraulic press, respectively. Then, two conveying mechanisms send the two blanks to the die and punch, respectively. However, when it is necessary to transfer the blank to the mold on the bearing platform, the blank must first be transferred to the bottom of a transfer mechanism, which then sends the blank to the mold on the bearing platform. However, since the blank is molten at this time, the middle of the blank falls downward under the action of gravity, causing the blank to stretch. This results in inconsistent wall thickness of the hot-pressed product, leading to poor product quality. Utility Model Content

[0030] This utility model proposes a hot pressing production system.

[0031] In the embodiments of this utility model, such as Figures 1 to 3As shown, the hot pressing production system includes a hot press 10, a first extruder 20, a second extruder 30, a first feeding mechanism 40, and a second feeding mechanism 50.

[0032] The hot press 10 has a pressure head 13 and a pressure platform 14 arranged opposite to each other. The pressure head 13 can be raised and lowered relative to the pressure platform 14. The pressure head 13 is provided with an upper mold 11, and the pressure platform 14 is provided with a lower mold 12. Both the upper mold 11 and the lower mold 12 are provided with several suction ports. The first extruder 20 is located on one side of the hot press 10, and the second extruder 30 is located on one side of the hot press 10. The first feeding mechanism 40 is located between the first extruder 20 and the hot press 10. The first feeding mechanism 40 is provided with a supporting platform 41. The supporting platform 41 has a first receiving position and a first feeding position. At the first receiving position, the supporting platform 41 is aligned with the first extruder. Corresponding to the extrusion port of 20, at the first feeding position, the carrying platform 41 is located inside the hot press 10 and close to the upper die 11; the second feeding mechanism 50 is located between the second extruder 30 and the hot press 10. The second feeding mechanism 50 is provided with a conveying component 51, which has a second receiving position and a second feeding position. At the second receiving position, the conveying component 51 corresponds to the extrusion port of the second extruder 30. At the second feeding position, the conveying component 51 is located inside the hot press 10 and close to the lower die 12. The conveying component 51 is configured to start conveying operations as it moves from the second feeding position to the second receiving position.

[0033] Specifically, the pressure head 13 can move up and down relative to the pressure platform 14 to apply pressure. The pressure head 13 is equipped with an upper mold 11, and the pressure platform 14 is equipped with a lower mold 12. Both molds are provided with multiple suction ports for absorbing gas or releasing pressure during the hot pressing process. One of the upper mold 11 and the lower mold 12 is a punch, and the other is a die.

[0034] The first feeding mechanism 40 is located between the first extruder 20 and the hot press 10, and is responsible for conveying the material extruded from the first extruder 20 to the hot press 10. The first feeding mechanism 40 includes a support platform 41, which has two positions: a first receiving position and a first feeding position. The support platform 41 corresponds to the extrusion port of the first extruder 20 at the first receiving position. During the process of moving from the first receiving position to the first feeding position, it receives the extruded material from the first extruder 20. When it moves to the first feeding position, the support platform 41 moves into the hot press 10 and corresponds to the upper mold 11. It then rises to transfer the extruded material into the upper mold 11 for thermoforming, and then descends to move towards the first receiving position, and the cycle repeats.

[0035] The first feeding mechanism 40 is located between the first extruder 20 and the hot press 10, and is responsible for conveying the material extruded by the second extruder 30 into the hot press 10. The second feeding mechanism 50 includes a conveying component 51, which has two positions: a second receiving position and a second feeding position. The conveying component 51 corresponds to the extrusion port of the second extruder 30 in the second receiving position and receives the material extruded by the second extruder 30 in the forward rotation state. When it moves to the second feeding position, the conveying component 51 moves into the hot press 10 and approaches the lower mold 12. At this time, the conveying component 51 moves from the second feeding position to the second receiving position and conveys the extruded material in the reverse rotation state. The extruded material gradually falls onto the lower mold 12 under the conveying of the conveying component 51. When the conveying component 51 completely withdraws from the hot press 10, the extruded material on the conveying component 51 falls completely onto the lower mold 12 for vacuum forming through the lower mold 12.

[0036] Subsequently, the pressure head 13 presses down to push the upper mold 11 and the lower mold 12 to close, so that the extruded material on the upper mold 11 and the extruded material on the lower mold 12 are thermoformed. Compared with the existing method that requires the blank to be transferred to the bottom surface of the transfer mechanism first, and then the blank is sent to the lower mold 12 by the transfer mechanism, the extruded material will not be stretched by the conveying component 51. In this way, the thermoformed product will not have uneven wall thickness, that is, the quality of the thermoformed product is improved.

[0037] Optionally, the first feeding mechanism 40 includes a first robotic arm connected to the support platform 41, used to drive the support platform 41 to move between the first receiving position and the first feeding position. Specifically, the connection between the first robotic arm and the support platform 41 enables automated movement of the support platform 41 between the first receiving position and the first feeding position. It also improves the mobility of the support platform 41. Furthermore, in other embodiments, the first feeding mechanism 40 includes a mounting bracket with a slide rail extending from the first extruder 20 toward the hot press 10, and the support platform 41 is slidably mounted on the mounting bracket.

[0038] Optionally, the second feeding mechanism 50 includes a second robotic arm connected to the conveying platform for driving the conveying component 51 to move between the second receiving position and the second feeding position.

[0039] Specifically, the second robotic arm is connected to the conveying component 51, enabling automated movement of the conveying component 51 between the second receiving position and the second feeding position. This also improves the mobility of the conveying component 51. Furthermore, in other embodiments, the second feeding mechanism 50 includes a mounting bracket with a slide rail extending from the first extruder 20 toward the hot press 10, and the conveying component 51 is slidably mounted on the mounting bracket.

[0040] This utility model's technical solution involves setting an upper mold 11 on the pressure head 13 of a hot press 10, and a lower mold 12 on the pressure platform 14, with both the upper mold 11 and the lower mold 12 having several suction ports; placing a first extruder 20 on one side of the hot press 10; placing a second extruder 30 on one side of the hot press 10; and placing a first feeding mechanism 40 between the first extruder 20 and the hot press 10. The first feeding mechanism 40 has a supporting platform 41, which has a first receiving position and a first feeding position. In the first receiving position, the supporting platform 41 corresponds to the extrusion port of the first extruder 20. In the first feeding position, the carrying platform 41 is located inside the hot press 10 and close to the upper die 11. The second feeding mechanism 50 is located between the second extruder 30 and the hot press 10. The second feeding mechanism 50 is provided with a conveying component 51. The conveying component 51 has a second receiving position and a second feeding position. In the second receiving position, the conveying component 51 corresponds to the extrusion port of the second extruder 30. In the second feeding position, the conveying component 51 is located inside the hot press 10 and close to the lower die 12. The conveying component 51 is configured to start conveying operations as it moves from the second feeding position to the second receiving position. In actual production, the carrying platform 41 and the conveying component 51 receive the extruded material from the first extruder 20 and the second extruder 30, respectively. After receiving the extruded material, they are simultaneously fed into the hot press 10. That is, the carrying platform 41 sends the extruded material to the position of the upper mold 11. The upper mold 11 receives the extruded material from the first feeding mechanism 40 through the negative pressure suction port and then performs thermoforming. The second feeding mechanism 50 sends the extruded material to the top of the lower mold 12 and moves it towards the second receiving position. During the movement, the conveying component 51 performs the conveying operation. Under the conveying of the conveying component 51, the extruded material gradually falls onto the lower mold 12 below. Compared with the existing method that requires transferring the blank to the bottom surface of the transfer mechanism first and then sending the blank to the lower mold 12 through the transfer mechanism, the extruded material will not be stretched by the conveying component 51. Thus, the hot-pressed product will not have uneven wall thickness, which improves the quality of the hot-pressed product.

[0041] In some embodiments, the hot pressing production system further includes a material handling robot 80, which is used to grasp the hot-pressed products. That is, the material handling robot 80 performs mechanical material handling, thereby automating the process and reducing labor costs.

[0042] Furthermore, the material handling robot 80 is also used to place the reinforcing bracket on the lower mold 12 after the extruded material has been vacuum-formed. In this way, after the upper mold 11 and the lower mold 12 are closed and vacuum-formed, the reinforcing structure can be located inside the vacuum-formed product, thereby improving the structural strength of the vacuum-formed product.

[0043] In some embodiments, the material handling robot 80 includes a robotic arm and a gripping part, the robotic arm being connected to the gripping part, and the surface of the gripping part being provided with a plurality of negative pressure suction ports.

[0044] Specifically, the hot-pressed product is fixed by negative pressure adsorption, which can prevent the surface of the hot-pressed product from being pinched and imprinted compared to the gripper method.

[0045] In some embodiments, the gripping part surface is provided with a flexible pad, and the flexible pad has a through hole corresponding to each negative pressure suction port. This avoids direct contact between the gripping part and the product, thereby preventing scratches or damage to the product surface. Furthermore, in other embodiments, the gripping part surface is not provided with a flexible pad.

[0046] In some embodiments, the hot pressing production system further includes a receiving mechanism 60, with a material handling robot 80 located between the hot press 10 and the receiving mechanism 60. The receiving mechanism 60 is used to receive products conveyed by the material handling robot 80. This facilitates the inspection and trimming of the conveyed products by the workers, reduces workflow, and improves production efficiency. Of course, in other embodiments, the hot pressing production system does not include a receiving mechanism 60.

[0047] In some embodiments, the material handling robot 80 is surrounded by a protective barrier 70. This is used to prevent personnel from entering the working area of ​​the material handling robot 80, thereby improving safety.

[0048] In some embodiments, the conveying component 51 includes a mounting frame, two rotating rollers, and a conveyor belt. The mounting frame is disposed between the second extruder 30 and the hot press 10. The two rotating rollers are rotatably mounted at both ends of the mounting frame, and the conveyor belt is sleeved between the two rotating rollers. Specifically, the two rotating rollers are respectively mounted at both ends of the mounting frame to drive the conveyor belt, and the conveyor belt is sleeved between the two rotating rollers to carry and convey the material. Setting the conveying component 51 as a conveyor belt structure helps to increase the contact area between the extruded material and the conveyor belt, and prevents the extruded material from stretching under gravity, which helps to improve the quality of the hot-pressed product.

[0049] In some embodiments, the upper mold 11 is provided with a plurality of clamping members on its periphery. The clamping members are arranged circumferentially along the upper mold 11, and each clamping member is rotatably disposed and has a clamped state and an open state. In the clamped state, the clamping member forms a clamping space with the surface of the upper mold 11. In the open state, the clamping member rotates to the periphery of the upper mold 11. Specifically, when the carrying platform 41 transfers the extruded material onto the upper mold 11, the upper mold 11 fixes the extruded material through the suction port while clamping the edges of the extruded material through the peripheral clamping members to prevent the extruded material from shifting during the thermoforming process and affecting the production quality of the thermoformed product.

[0050] In some embodiments, the first extruder 20 and the second extruder 30 are located on the same side of the hot press 10, and are stacked vertically. Specifically, by arranging the first extruder 20 and the second extruder 30 on the same side of the hot press 10 and in a stacked manner, the length of the hot pressing production system can be reduced, and it also facilitates equipment monitoring, maintenance, and material management by the staff, thereby improving production efficiency.

[0051] In some embodiments, the feed inlets of the first extruder 20 and the second extruder 30 are staggered. This arrangement facilitates the addition of raw materials to the first extruder 20 and the second extruder 30 by the operator.

[0052] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
