Description

Technical Field

[0001] This utility model relates to a high-efficiency extrusion molding device for double honeycomb panels, belonging to the technical field of honeycomb panel processing. Background Technology

[0002] In the field of lightweight building materials and transportation equipment manufacturing, plastic double honeycomb panels have seen a continuous increase in market demand due to their excellent properties such as lightweight, high strength, sound insulation, and heat insulation. Extrusion molding is the core process in the production of plastic honeycomb panels, and the performance of its equipment directly determines product quality and production efficiency.

[0003] Currently, most traditional extrusion equipment uses a single discharge port design. However, when producing wide plastic honeycomb panels, it is difficult for the material to be distributed quickly and evenly throughout the width of the die. This can easily lead to inconsistent material amounts between the edges and the center, resulting in uneven panel thickness and asymmetrical honeycomb structures. This severely weakens the product's appearance and mechanical properties. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency extrusion molding device for double honeycomb panels, which enables the material to be quickly and evenly distributed throughout the width direction in the mold when producing wide plastic honeycomb panels, ensuring that the amount of material at the edges and the center is consistent.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A high-efficiency extrusion molding device for double honeycomb panels includes a frame, an extruder fixed to the top of the frame, and a mounting plate at the front end of the extruder. A main discharge pipe is fixed to the midpoint of the side of the mounting plate, and secondary discharge pipes are provided at both ends of the side of the mounting plate. Slide grooves are opened at both ends of the side of the mounting plate, and a lead screw is transversely arranged in the slide groove. A movable block is slidably connected inside the slide groove, and the lead screw passes through the movable block and is threadedly connected to it. The secondary discharge pipes are installed on the movable block.

[0007] The top of the mounting plate is provided with a drive mechanism, which is used to drive the lead screw to rotate.

[0008] Preferably, the drive mechanism includes a motor, the output end of which is connected to a first bevel gear, and the two ends of the first bevel gear are meshed with a second bevel gear. Both the first and second bevel gears are installed inside the mounting plate, and the second bevel gear is connected to a lead screw.

[0009] Preferably, the extruder is provided with a feed hopper at the top and a discharge pipe is fixed at the front end of the extruder. A three-way valve is fixed on the outside of the discharge pipe, and the three-way valve is connected to the main discharge pipe and two sets of auxiliary discharge pipes through multiple sets of connecting pipes respectively.

[0010] Preferably, the three-way valve is equipped with multiple flow controllers.

[0011] Preferably, mounting brackets are fixed to both ends of the side of the mounting plate, and fixing sleeves are fixed to both ends of the outer side of the extruder. The mounting brackets penetrate the fixing sleeves, and the fixing sleeves are provided with locking mechanisms.

[0012] Preferably, the locking mechanism includes a locking rod that extends through the top of the fixing sleeve. The mounting bracket has several sets of slots. One end of the locking rod is located in the slot, and the other end of the locking rod is fixed with a pull ring. A spring is sleeved on the outside of the locking rod, and the two ends of the spring are respectively connected to the fixing sleeve and the pull ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The main discharge pipe is responsible for supplying materials to the central area of ​​the board, while the auxiliary discharge pipes on both sides are responsible for supplying materials to the edge areas of the board, forming a central plus double-sided material supply mode. With the help of a three-way valve and flow controller, the discharge volume of the main and auxiliary discharge pipes can be reasonably adjusted, which can make the material spread quickly and evenly in the mold, so that the material quantity in all parts of the board is consistent, thereby ensuring that the thickness tolerance of the honeycomb board and the symmetry of the honeycomb cells meet the standards, and significantly improving the quality of the board.

[0015] The two sets of auxiliary discharge pipes can be moved and adjusted according to the size of the honeycomb panels being produced, providing high flexibility. When it is necessary to produce honeycomb panels of different widths, there is no need to replace the entire set of molds. Simply by adjusting the position of the auxiliary discharge pipes, the range of material supply width can be changed, enabling the production of honeycomb panels of various specifications to be adapted. This greatly reduces the cost and time of mold replacement, improves production efficiency, and allows the equipment to better meet diverse market demands. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A high-efficiency extrusion molding device for double honeycomb panels includes a frame 1, an extruder 2 fixed on the top of the frame 1, an installation plate 3 at the front end of the extruder 2, a main discharge pipe 4 fixed at the midpoint of the side of the installation plate 3, and auxiliary discharge pipes 5 at both ends of the side of the installation plate 3. Slide grooves are opened at both ends of the side of the installation plate 3, and a lead screw 6 is transversely arranged in the slide groove. A movable block 7 is slidably connected inside the slide groove. The lead screw 6 passes through the movable block 7 and is threadedly connected to it. The auxiliary discharge pipes 5 are installed on the movable block 7.

[0024] The top of the mounting plate 3 is provided with a drive mechanism 8, which is used to drive the lead screw 6 to rotate.

[0025] Furthermore, during use, the main discharge pipe 4 is responsible for supplying material to the center of the board, while the two sets of auxiliary discharge pipes 5 are responsible for supplying material to the edge of the board, thereby ensuring the consistency of material quantity at the center and edge of the board. The distance between the two sets of auxiliary discharge pipes 5 can be adjusted by the drive mechanism 8 to change the range of material supply width, thus achieving production adaptation for various specifications of honeycomb panels.

[0026] In this embodiment: the drive mechanism 8 includes a motor 801, the output end of the motor 801 is connected to a bevel gear 802, and the two ends of the bevel gear 802 are meshed with bevel gear 803. Both the bevel gear 802 and the bevel gear 803 are installed inside the mounting plate 3, and the bevel gear 803 is connected to the lead screw 6.

[0027] Furthermore, by driving the bevel gear 802 to rotate via the motor 801, the bevel gear 802 can drive the two sets of lead screws 6 to rotate via the two sets of meshing bevel gears 803.

[0028] In this embodiment: a feed hopper 9 is provided on the top of the extruder 2, and a discharge pipe 10 is fixed at the front end of the extruder 2. A three-way valve 11 is fixed on the outside of the discharge pipe 10, and the three-way valve 11 is connected to the main discharge pipe 4 and two sets of auxiliary discharge pipes 5 respectively through multiple sets of connecting pipes 13.

[0029] Furthermore, the molten plastic raw material can be distributed and discharged into the main discharge pipe 4 and the auxiliary discharge pipe 5 through the three-way valve 11 and multiple sets of connecting pipes 13.

[0030] In this embodiment: the three-way valve 11 is equipped with multiple flow controllers 12.

[0031] Furthermore, the flow controller 12 can uniformly monitor and distribute the material flow rate, ensuring that the discharge volume of the main discharge pipe 4 and the auxiliary discharge pipe 5 is consistent.

[0032] In this embodiment: mounting brackets 14 are fixed at both ends of the side of the mounting plate 3, and fixing sleeves 15 are fixed at both ends of the outer side of the extruder 2. The mounting brackets 14 pass through the fixing sleeves 15, and a locking mechanism 16 is provided on the fixing sleeves 15.

[0033] Furthermore, the mounting plate 3 can be installed by inserting the two sets of mounting brackets 14 on the mounting plate 3 into the fixing sleeves 15 on both sides of the extruder 2. The mounting brackets 14 and the mounting plate 3 can be locked together with the locking mechanism 16.

[0034] In this embodiment: the locking mechanism 16 includes a locking rod 1601, which is disposed through the top of the fixed sleeve 15. The mounting bracket 14 has several sets of slots. One end of the locking rod 1601 is located in the slot, and the other end of the locking rod 1601 is fixed with a pull ring 1602. A spring 1603 is sleeved on the outside of the locking rod 1601, and the two ends of the spring 1603 are respectively connected to the fixed sleeve 15 and the pull ring 1602.

[0035] Furthermore, by pulling the pull ring 1602 upwards to pull the locking lever 1601 out of the slot on the mounting bracket 14, the locking of the mounting bracket 14 and the mounting plate 3 can be released. The elastic force of the spring 1603 can cause the pull ring 1602 to generate a downward force so that the locking lever 1601 can be inserted into the slot to lock the mounting bracket 14.

[0036] The workflow of this embodiment is as follows: During use, plastic can be fed into the feed hopper 9 and introduced into the extruder 2 for heating and melting. After the material melts, the auger inside the extruder 2 will extrude the raw material into the discharge pipe 10. The three-way valve 11 on the outside of the discharge pipe 10 will divert the raw material. The flow controller 12 will monitor and distribute the material flow in real time. Afterwards, the material will be discharged into the mold through the connecting pipe 13 into the main discharge pipe 4 and two sets of auxiliary discharge pipes 5. The main discharge pipe 4 is responsible for feeding the material to the center of the sheet, and the two sets of auxiliary discharge pipes 5 are responsible for feeding the material to the edge of the sheet, thus ensuring the consistency of the material quantity at the center and edge of the sheet. When it is necessary to produce honeycomb panels of different widths, the motor 801 can be turned on to drive the bevel gear 802 to rotate. This will cause the bevel gear 802 to drive the two sets of lead screws 6 to rotate through the two sets of meshing bevel gears 803. The two sets of lead screws 6 will drive the two sets of movable blocks 7 and the auxiliary discharge pipes 5 to move and adjust their position relative to the main discharge pipe 4. The spacing allows for adjustment of the feeding width range simply by changing the position of the secondary discharge pipe 5, enabling production adaptation to various specifications of honeycomb panels. During the production of plastic honeycomb panels, the main discharge pipe 4 and secondary discharge pipe 5 may require cleaning due to material residue, impurities clogging, or component wear. By pulling the pull ring 1602 upwards, the locking rod 1601 can be pulled out of the slot on the mounting frame 14, thus releasing the locking of the mounting frame 14 and mounting plate 3. Afterwards, the mounting frame 14 can be pulled out of the fixing sleeve 15 to disassemble the mounting plate 3. This technical solution allows for convenient disassembly of the main discharge pipe 4 and secondary discharge pipe 5 in a short time. Maintenance personnel can inspect, clean, and replace parts of the main discharge pipe and secondary discharge pipe without the need for complex tools or cumbersome disassembly procedures. Compared with the traditional fixed connection method, equipment maintenance time can be shortened by more than 60%, greatly reducing downtime and ensuring the efficient operation of the production line.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
