Description

Technical Field

[0001] This invention belongs to the technical field of non-ferrous metal die casting equipment, specifically a non-ferrous metal die casting cavity forming mechanism for aerospace hardware handles. Background Technology

[0002] Hardware handles used in aviation airborne equipment, aircraft doors, and aircraft cabinets are key appearance and load-bearing components in aviation. They are generally made of lightweight non-ferrous metals such as aluminum alloy and magnesium alloy through die casting, meeting the requirements of lightweight, high strength, and corrosion resistance. Compared with civilian hardware handles, aviation hardware handles require dimensional tolerances of ≤±0.02mm, and the overall molding precision and mechanical properties are extremely stringent. Therefore, they are produced using precision die casting molds.

[0003] However, existing conventional die-casting cavity forming mechanisms have some drawbacks in use: First, conventional molds use straight-tube direct-flow water channels, which cannot conform to the temperature control of irregularly shaped handles, resulting in uneven cooling of the workpiece and inconsistent cooling shrinkage, which easily leads to arc-shaped warping deformation and cannot meet the high-precision assembly requirements of aerospace; Second, depending on the application, the shape of the handle will also be different, and conventional forming mechanisms require a long time to operate when changing different molds, which greatly reduces work efficiency.

[0004] Therefore, it is necessary to provide a new non-ferrous metal die-casting cavity forming mechanism for aviation hardware handles to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a non-ferrous metal die-casting cavity forming mechanism for aerospace hardware handles that can quickly switch the corresponding forming mold, improve forming efficiency, ensure uniform cooling of the handle as a whole, and eliminate deformation defects.

Four lower forming molds and four upper forming molds are provided above the switching platform. A switching component is provided on the switching platform for quickly switching between different forming molds. Forming cavities are formed on the sides of the four lower forming molds and the four upper forming molds that are close to each other. Cooling chambers are formed within the four lower forming molds and the four upper forming molds. The cooling chambers are adapted to the shape of the forming cavities, and the forming cavities are surrounded by the cooling chambers. The wall thickness between the forming cavities and the cooling chambers is 8-10 mm. The water supply component is used to introduce coolant.

In use, the two lower mold water pipes are respectively attached to both sides of the lower forming mold and connected to the water passage holes. The lower mold water pipes are fixedly installed with a first sealing ring on the end side near the lower forming mold. Both first sealing rings are attached to the lower forming mold. The two upper mold water pipes are respectively attached to both sides of the upper forming mold and connected to the water passage holes. The upper mold water pipes are fixedly installed with a second sealing ring on the end side near the upper forming mold. Both second sealing rings are attached to the upper forming mold.

[0011] Furthermore, both hollow connecting plates are provided with adjustment slots, and each of the two lower mold water pipes and the two upper mold water pipes is fixedly fitted with a limiting slider. Each of the four limiting sliders passes through the corresponding adjustment slot and fits against the inner wall of the corresponding adjustment slot. Each of the four limiting sliders is threaded with a locking bolt, and each of the four locking bolts has a knob head at its end, which abuts against one side of the hollow connecting plate. This allows the lower mold water pipes and upper mold water pipes to be adjusted according to the height of the water passage holes of the lower and upper molds of different specifications. Both of the supporting brackets are provided with movable openings to provide installation and movement space for the water passage components.

[0012] Furthermore, a forming support is provided below the support frame, and two I-beams are provided between the forming support and the support frame. A lifting hydraulic cylinder is fixedly installed between the two I-beams, and the output shaft of the lifting hydraulic cylinder is fixedly connected to the support frame.

Each of the four reserved grooves has a push plate, and the push plate is adapted to the internal size of the reserved groove. During die casting, the bottom end face of the push plate will not protrude into the forming cavity. A push rod is slidably installed on the top of each of the four upper forming molds.

Next, each of the four L-shaped mounting strips has a stop bar fixedly installed at its bottom. The bottom ends of the four stop bars extend into the four second portal frames and slide to connect with the top of the corresponding second portal frames. Each of the four stop bars is adapted to a connector. When the upper forming mold rises, the stop bars automatically push the connectors, and the connectors, along with the push plates, descend, automatically ejecting the workpiece that has been formed in the upper forming mold. Each of the four connectors has a triangular groove on one side, and each of the four second portal frames has a first double shaft fixedly installed on one outer wall. The output shafts of the four first dual-axis cylinders all pass through one side of the corresponding second portal frame and are slidably connected to one side of the corresponding second portal frame. Each of the four first dual-axis cylinders has a wedge-shaped abutment plate fixedly installed on its output shaft. The four wedge-shaped abutment plates are respectively adapted to the four triangular grooves. After the lower forming mold and the upper forming mold are locked, the output shaft of the first dual-axis cylinder extends out and uses the wedge-shaped abutment plates to push into the triangular grooves and form a resisting force, ensuring that the push plate stays stably in the reserved groove and does not interfere with the subsequent forming work.

[0015] Furthermore, a third rodless cylinder is fixedly installed on the top of the connecting platform. A vertical connecting arm is fixedly installed on the slider of the third rodless cylinder. A horizontal connecting arm is fixedly installed on the side of the vertical connecting arm near the switching platform. A fourth rodless cylinder is fixedly installed on the horizontal connecting arm. An installation arm is fixedly installed on the slider of the fourth rodless cylinder.

A distance sensor is fixedly installed at the bottom of the installation arm to control the descent height of the gripper cylinder. An infrared sensor is fixedly installed on the top of the switching platform. The infrared sensor is slightly higher than the top end face of the lower forming mold. When a workpiece accidentally stops inside the lower forming mold, the infrared sensor senses the workpiece and uses the gripper cylinder to clamp the workpiece onto the belt conveyor assembly.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] First embodiment:

[0040] Please refer to the following: Figures 1-13 The non-ferrous metal die-casting cavity forming mechanism for aviation hardware handles includes: a switching platform 2, a water supply component, and a mold locking component. Four lower forming molds 203 and four upper forming molds 303 are provided above the switching platform 2. One set of molds corresponds to one lower forming mold 203 and one upper forming mold 303. In this embodiment, there are four sets, and the forming cavities 4 in each set of molds are different. A switching component is provided on the switching platform 2 for quickly switching between different forming molds. This switching component includes a switching shaft 201 rotatably mounted on the switching platform 2. A cross-shaped fixing bracket 202 is fixed to the top of the switching shaft 201. The four ends of the cross-shaped fixing bracket 202 are respectively fixedly connected to the four lower forming molds 203. A die-casting channel 204 is opened at the bottom of each of the four lower forming molds 203. A support frame 6 is fixed to the bottom of the switching platform 2. A switching servo motor 601 is fixed inside the support frame 6. Switching gears are fixedly sleeved on both its output shaft and the switching shaft 201. The two switching gears mesh with each other. In addition, the switching servo motor 601 performs reciprocating forward and reverse rotation to prevent external wiring from becoming entangled.

[0041] In this embodiment, to achieve a comprehensive cooling effect, forming cavities 4 are provided on the sides of the four lower forming molds 203 and the four upper forming molds 303 that are close to each other. Cooling chambers 5 are also provided within the four lower forming molds 203 and the four upper forming molds 303. The cooling chambers 5 are shaped to fit the forming cavities 4, and the forming cavities 4 are surrounded by the cooling chambers 5. The wall thickness between the forming cavities 4 and the cooling chambers 5 is 9mm. Through the appropriately shaped cooling chambers 5, comprehensive cooling of the workpiece can be achieved, ensuring uniform and effective cooling. A water-passing assembly is used to introduce coolant, and this assembly includes two support frames 7. Two support frames 7 are fixed on both sides of the switching table 2. A first rodless cylinder 701 is fixed on each support frame 7. A hollow connecting plate 702 is fixed on the slider of each of the two first rodless cylinders 701. A connecting pipe 703 is fixed on the side of each hollow connecting plate 702 that is furthest from each other. A first corrugated pipe 704 is fixed on each of the two support frames 7. The ends of the two connecting pipes 703 that are furthest from each other are fixedly connected to one end of each of the two first corrugated pipes 704. A lower mold water pipe 705 and an upper mold water pipe 706 are provided inside each of the two hollow connecting plates 702. A hollow connecting pipe 705 is fixed on each of the two connecting pipes 703. There are two second corrugated pipes 707, and the bottom ends of two lower mold water pipes 705 and two upper mold water pipes 706 are fixedly connected to the top ends of the four second corrugated pipes 707 respectively. Water passage holes communicating with the cooling chamber 5 are opened on both sides of the four lower forming molds 203 and the four upper forming molds 303. These water passage holes can be used in conjunction with the lower mold water pipes 705 and the upper mold water pipes 706 to smoothly deliver coolant into the cooling chamber 5. A coolant pump 8 is fixed on one outer wall of the support frame 6, and its outlet port is connected to one of the first corrugated pipes 704 through a liquid guide pipe 9. Pipe 704 is connected to an external wastewater tank via a flexible hose. During use, the two lower mold water pipes 705 are respectively attached to both sides of the lower forming mold 203 and connected to the water passage holes. The lower mold water pipe 705 is fixed with a first sealing ring near the end of the lower forming mold 203. Both first sealing rings are attached to the lower forming mold 203. The two upper mold water pipes 706 are respectively attached to both sides of the upper forming mold 303 and connected to the water passage holes. The upper mold water pipe 706 is fixed with a second sealing ring near the end of the upper forming mold 303. Both second sealing rings are attached to the upper forming mold 303 to ensure sealing performance.In addition, to improve applicability, adjusting slides are provided on both hollow connecting plates 702, and limiting sliders are fixedly fitted on both lower mold water pipes 705 and both upper mold water pipes 706. All four limiting sliders pass through their corresponding adjusting slides and fit against the inner wall of the corresponding adjusting slides. Locking bolts are threaded onto each of the four limiting sliders, and each locking bolt has a knob head at its end, which abuts against one side of the hollow connecting plate 702. This allows the lower mold water pipes 705 and upper mold water pipes 706 to be adjusted according to the height of the water passage holes of the lower forming mold 203 and upper forming mold 303 of different specifications. Movable openings are provided on both support brackets 12 to provide installation and movement space for the water passage components.

[0042] In this embodiment, the mold-locking assembly is connected to the upper molding mold 303 to create a mold-locking effect between the upper molding mold 303 and the lower molding mold 203. The mold-locking assembly includes a linkage turntable 301, with a central shaft fixed to the bottom of the turntable 301. The bottom end of the central shaft is fixedly connected to a cross-shaped fixing frame 202, thus enabling a linkage effect with the cross-shaped fixing frame 202. Four mold-locking hydraulic cylinders 302 are fixed to the top of the linkage turntable 301. A first portal frame 10 is fixed to the output shaft of each of the four mold-locking hydraulic cylinders 302. A second portal frame 1001 is fixed to the bottom of each of the four first portal frames 10. The bottoms of the four second portal frames 1001 are respectively connected to the four... Each of the four upper forming molds 303 is fixedly connected to a pre-reserved groove 1002, which is connected to the corresponding forming cavity 4. Each of the four pre-reserved grooves 1002 has a pusher plate 1003, and the pusher plate 1003 is adapted to the internal dimensions of the pre-reserved groove 1002. During die casting, the bottom end face of the pusher plate 1003 will not protrude into the forming cavity 4. Each of the four upper forming molds 303 has a pusher rod 1004 slidably mounted on its top. Each of the four pusher rods 1004 has a connector 1005 fixed to its top. Each of the four pusher rods 1004 has a return spring 1006 sleeved on it. The top of the four springs 1006 is fixedly connected to four connectors 1005 respectively. The bottom of the four return springs 1006 is fixedly connected to four upper forming molds 303 respectively. The bottom of the linkage turntable 301 is fixed with four L-shaped mounting strips 1007. One side of each of the four L-shaped mounting strips 1007 extends into the four first portal frames 10 and slides in connection with the corresponding first portal frame 10. The bottom of each of the four L-shaped mounting strips 1007 is fixed with an abutment rod 1008. The bottom of each of the four abutment rods 1008 extends into the four second portal frames 1001 and slides in connection with the top of the corresponding second portal frame 1001. The four abutment rods 1008 are respectively connected to the four connectors 1005. 05-phase compatibility; when the upper forming mold 303 rises, the abutment rod 1008 automatically pushes the connector 1005, and the connector 1005 descends with the push plate 1003, automatically ejecting the workpiece that is stuck in the upper forming mold 303. In the initial state, the abutment rod 1008 pushes the connector 1005, so that the push plate 1003 stays in the forming cavity 4, and the return spring 1006 is in a compressed state at this time. When the output shaft of the mold locking hydraulic cylinder 302 is extended, the abutment rod 1008 separates from the connector 1005, the return spring 1006 automatically resets, and the push plate 1003 is automatically brought into the reserved groove 1002 without affecting the forming effect.Furthermore, to further ensure that the pusher plate 1003 will not move during the die-casting process, a triangular groove 1009 is provided on one side of each of the four connectors 1005. This triangular groove 1009 is a right-angled triangle. A first dual-axis cylinder 10010 is fixed to the outer wall of one side of each of the four second portal frames 1001. The output shafts of the four first dual-axis cylinders 10010 pass through one side of the corresponding second portal frame 1001 and are slidably connected to one side of the corresponding second portal frame 1001. Each of the four first dual-axis cylinders 10010 has a wedge-shaped contact piece 10011 fixed on its output shaft. The four wedge-shaped contact pieces 10011 are respectively adapted to four triangular grooves 1009. After the lower forming mold 203 and the upper forming mold 303 are locked, the output shafts of the first dual-axis cylinders 10010 extend, using the wedge-shaped contact pieces 10011 to push into the triangular grooves 1009 and form a resisting force, ensuring that the pusher piece 1003 remains stably in the reserved groove 1002 without interfering with subsequent molding operations.

[0043] In this embodiment, in order to improve the stability of the cross fixing frame 202 and the linkage turntable 301 during rotation, two support brackets 12 are fixed on the top of the switching platform 2. The two support brackets 12 are designed in an inverted "L" shape. A connecting plate 3 is provided above the linkage turntable 301. The connecting plate 3 is fixedly connected to the two support brackets 12 through two columns. A linkage shaft is rotatably installed at the bottom of the connecting plate 3. The bottom end of the linkage shaft is fixedly connected to the linkage turntable 301. An external die-casting pipe 11 is provided below the switching platform 2. The external die-casting pipe 11 is connected to an external die-casting equipment. The top of the external die-casting pipe 11 passes through the switching platform 2 and is slidably connected to the switching platform 2. The end of the external die-casting pipe 11 is attached to the bottom of one of the lower forming molds 203 and communicates with the die-casting channel 204.

[0044] In this embodiment, to facilitate quick removal of coolant, a forming support 1 is provided below the support frame 6. Two I-beam steel support beams 602 are provided between the forming support 1 and the support frame 6. A single lifting hydraulic cylinder 603 is fixed between the two I-beam steel support beams 602. The output shaft of the lifting hydraulic cylinder 603 is fixedly connected to the support frame 6. By extending the output shaft of the lifting hydraulic cylinder 603, the die-casting channel 204 at the bottom of the lower forming mold 203 is separated from the outer die-casting pipe 11, facilitating the switching of lower forming molds 203 of different specifications. The two I-beam steel... The top of each support beam 602 is slidably mounted with a stabilizing slide rod. The top of each of the four stabilizing slide rods is fixedly connected to the support frame 6. The bottom of the C-shaped steel support beam 602 away from the coolant pump 8 is hinged to the forming support 1. The bottom of the C-shaped steel support beam 602 close to the coolant pump 8 is slidably mounted with a sliding block 605. A drain hydraulic cylinder 604 is fixed on the forming support 1. The output shaft of the drain hydraulic cylinder 604 is hinged to the sliding block 605. By extending the output shaft of the drain hydraulic cylinder 604, the entire switching platform 2 is tilted, thereby quickly draining the coolant.

[0045] In this embodiment, the inlet port of the coolant pump 8 is also connected to the external coolant tank via a hose. Before die casting, a suitable lower die 203 and upper die 303 are selected according to requirements. During selection, the output shaft of the lifting hydraulic cylinder 603 is extended to separate one of the lower die 203s that is in contact with the external die casting pipe 11 from the external die casting pipe 11. The switching servo motor 601 is then started, and its output shaft drives the corresponding switching gear to rotate. The meshing of the two switching gears causes the switching shaft 201 to rotate with the cross fixing bracket 202. During rotation, the linkage turntable 301 also rotates synchronously under the linkage of the shaft rod. The cross fixing bracket 202 pauses every 90° rotation. Next, the switching servo motor 601 is turned off after the lower forming mold 203 and the upper forming mold 303, which meet the requirements, rotate to above the outer die-casting pipe 11. In addition, in the initial state, the lower mold water pipe 705 and the upper mold water pipe 706 are far away from the entire lower forming mold 203 and will not interfere with the rotation of the lower forming mold 203. After selecting the required lower forming mold 203 and upper forming mold 303, the height of the lower mold water pipe 705 and the upper mold water pipe 706 is adjusted according to the height position of the water passage hole. When adjusting, loosen the locking bolt, and then adjust the height of the lower mold water pipe 705 and the upper mold water pipe 706 up and down. After adjusting to the specified position, tighten the locking bolt again.

[0046] During die casting, the corresponding clamping hydraulic cylinder 302 is activated, and its output shaft drives the corresponding upper forming mold 303 to descend, eventually fitting with the lower forming mold 203 below. The forming cavities 4 of the two molds together form a complete forming space. During the descent, the abutment rod 1008 separates from the connector 1005, and the compressed return spring 1006 returns to its original position, allowing the push plate 1003 to naturally settle in the reserved groove 1002. Then, the output shaft of the corresponding first dual-axis cylinder 10010 is activated to extend, pushing the corresponding wedge-shaped abutment plate 10011 into the triangular groove 1009. Utilizing the abutment effect of the two, the push plate 1003 is perfectly engaged in the reserved groove 1002. Subsequently, the... Two first rodless cylinders 701 are activated, and the sliders on them move the corresponding hollow connecting plates 702 toward the lower forming mold 203. This causes the two lower mold water pipes 705 to mate with the water passages on both sides of the lower forming mold 203, and the two upper mold water pipes 706 to mate with the water passages on both sides of the upper forming mold 303. The coolant pump 8 is then activated, and the coolant flows sequentially through the coolant pump 8, the guide pipe 9, the first corrugated pipe 704, the connecting pipe 703, and the second corrugated pipe 707 into one set of lower mold water pipes 705 and upper mold water pipes 706. The coolant then flows into the cooling chambers 5 in the lower forming mold 203 and the upper forming mold 303, and is discharged through the other first corrugated pipe 704.

[0047] The external die-casting equipment is started, and the non-ferrous metal liquid is injected into the die-casting channel 204 through the external die-casting pipe 11, and finally enters the forming cavity 4 for forming. During the forming process, the coolant adheres to the forming cavity 4 to achieve precise circulation cooling.

[0048] After molding is completed, the hose between the coolant pump 8 and the external coolant tank can be pulled out. Then, the output shaft of the drain hydraulic cylinder 604 is extended. Under the sliding action of the sliding block 605, the support frame 6 and the switching table 2 rotate around the hinge between the support frame 6 and the C-shaped steel support beam 602, so that the circulating coolant can be drained quickly.

[0049] Then, the output shaft of the drainage hydraulic cylinder 604 is retracted, and then the two first rodless cylinders 701 are activated to remove the water pipes 705 and 706 from the lower forming mold 203 and the upper forming mold 303. Immediately afterward, the output shaft of the first dual-axis cylinder 10010 is retracted, so that the push plate 1003 is naturally placed in the reserved groove 1002. The mold locking hydraulic cylinder 302 is activated to rise. Usually, the formed workpiece rises synchronously with the upper forming mold 303. During the rising process, the workpiece is collected below the upper forming mold 303. When the contact rod 1008 contacts the connector 1005, it will automatically push the connector 1005. The push rod 1004, along with the push plate 1003, descends. At this time, the return spring 1006 is compressed, and the formed workpiece is successfully pushed out, completing the collection.

[0050] Then repeat the above steps to form a continuous molding process.

[0051] Second embodiment:

[0052] Based on the non-ferrous metal die-casting cavity forming mechanism for aerospace hardware handles provided in the first embodiment of this application, the second embodiment of this application proposes another non-ferrous metal die-casting cavity forming mechanism for aerospace hardware handles. The second embodiment is merely a further embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0053] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0054] Please refer to the following: Figures 14-17 The non-ferrous metal die-casting cavity forming mechanism for aviation hardware handles also includes a mounting panel 13 fixed between two support brackets 12. A connecting crossbeam 14 is fixed on the mounting panel 13. A second dual-axis cylinder 15 is fixed on the top of the connecting crossbeam 14. Its output shaft passes through the connecting crossbeam 14 and is slidably connected to the connecting crossbeam 14. A second rodless cylinder 1501 is fixed on the output shaft of the second dual-axis cylinder 15. A receiving channel steel 1502 is fixed on the slider of the second rodless cylinder 1501. The receiving channel steel 1502 is inclined. A belt conveyor assembly 17 is provided below the receiving channel steel 1502.

[0055] In this embodiment, in order to remove the workpiece stuck in the lower forming mold 203, a third rodless cylinder 16 is fixed to the top of the connecting platform 14, a vertical connecting arm 1601 is fixed to its slider, a horizontal connecting arm 1602 is fixed to the side of the vertical connecting arm 1601 near the switching platform 2, a fourth rodless cylinder 1603 is fixed to the horizontal connecting arm 1602, a mounting arm 1604 is fixed to the slider of the fourth rodless cylinder 1603, a gripper cylinder 1605 is fixed to the mounting arm 1604, the gripper cylinder 1605 is located above the belt conveyor assembly 17, and a distance sensor 1 is fixed to the bottom of the mounting arm 1604. 606, the descent height of the gripper cylinder 1605 can be controlled. An infrared sensor 1607 is fixed on the top of the switching table 2. The infrared sensor 1607 is slightly higher than the top end face of the lower forming mold 203. When the formed workpiece accidentally stops in the lower forming mold 203, the infrared sensor 1607 senses the workpiece and uses the gripper cylinder 1605 to grip the workpiece onto the belt conveyor assembly 17. At the same time, it is located below the belt conveyor assembly 17, so that the gripper cylinder 1605 will not be interfered with by foreign objects when moving. In addition, in order to prevent the workpiece from being pinched, a buffer pad is set on the gripper of the gripper cylinder 1605 to form effective protection.

[0056] In all the above embodiments, the electronic components involved, such as the switching servo motor 601, the coolant pump 8, the distance sensor 1606, and the infrared sensor 1607, are all controlled by an external controller, which is a conventional operation method in this technical field, and will not be described in detail here.

[0057] In this embodiment, after molding is completed, during the upward movement of the upper molding die 303, and before the contact rod 1008 contacts the connector 1005, the second dual-axis cylinder 15 is simultaneously activated. Its output shaft lowers the receiving channel steel 1502, and the second rodless cylinder 1501 is activated. Its slider moves horizontally with the receiving channel steel 1502, eventually moving to below the upper molding die 303. Throughout the process, the contact rod 1008 still does not contact the connector 1005. Afterward, when the contact rod 1008 contacts the connector 1005, the workpiece will be automatically ejected. The workpiece falls into the receiving channel steel 1502 and automatically slides onto the belt conveyor assembly 17 for transmission to the next process.

[0058] Then, the second rodless cylinder 1501 and the second dual-shaft cylinder 15 are reversed to bring the receiving channel steel 1502 back to its original position.

[0059] During subsequent material handling, if a workpiece accidentally becomes stuck inside the lower forming mold 203, the infrared sensor 1607 detects it and transmits a signal. The third rodless cylinder 16 is activated, and its slider moves horizontally along with the horizontal connecting arm 1602, eventually bringing the gripper cylinder 1605 directly above the lower forming mold 203. Then, the fourth rodless cylinder 1603 is activated, and its slider descends along with the mounting arm 1604. Based on the distance sensor 1606, when the gripper cylinder 1605 descends to a position slightly above the top of the lower forming mold 203... When the fourth rodless cylinder 1603 stops, the workpiece handle is between the two jaws of the gripper cylinder 1605. The gripper cylinder 1605 is activated to grip the workpiece, and then the fourth rodless cylinder 1603 is activated to remove it from the lower forming mold 203. Then the third rodless cylinder 16 is activated to bring the gripper cylinder 1605 back to its original position. The fourth rodless cylinder 1603 is activated again to bring the gripper cylinder 1605 down to a low position above the belt conveyor assembly 17, whereby the workpiece can be released and allowed to fall onto the belt conveyor assembly 17 for conveying.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
