Description

Technical Field

[0001] This invention relates to the technical field of cold copper processing equipment for copper smelting, and more particularly to a tray for loading onto a scrap handling machine. Background Technology

[0002] In current copper smelting production, copper ingots made from recycled new energy copper materials are a key source of purchased cold copper. They have high copper grade and stable supply, ensuring production continuity. However, the traditional converter direct-injection process has obvious drawbacks: the demolding material left over from pressing the copper ingots forms impurities, and the reaction at high temperatures produces a large amount of flames and black smoke, which not only causes environmental indicators to exceed standards, but also poses fire safety hazards to the crane. At the same time, market fluctuations lead to a shortage of regular cold copper that can be directly used in the machine, while copper ingot inventory is seriously backlogged, creating a contradiction between idle resources and production demand.

[0003] To solve the above problems, after technical coordination with cold copper manufacturers and in combination with on-site working conditions, a solution of "packing copper ingots and then feeding them onto the feeder" was determined. This solution uses pallets to support the packaged copper ingots to form "copper crowns", which are then conveyed to the feeder mechanism of the feeder via a conveyor chain. The feeder mechanism flips the copper ingots from a horizontal position to a vertical position before feeding them into the converter. This not only revitalizes the stockpiled copper ingot resources and makes up for the cold copper supply gap, but also completely avoids the environmental and safety risks brought about by direct feeding.

[0004] However, existing pallets have three major flaws that severely limit the effectiveness of the solution:

[0005] Firstly, existing pallets are mostly multi-module splicing structures. During assembly, it is necessary to repeatedly align and adjust the edges of each plate to ensure that the outer surface is on the same horizontal plane, which is time-consuming and labor-intensive. Moreover, the assembly and fixing rely on a large number of screws. The screws are made of ordinary steel, which will be completely burned in the high-temperature operation environment of the subsequent loading machine. The burnt screw remnants are mixed into the copper ingot, which leads to an increase in the steel content of the cold copper and affects the purity of subsequent smelting.

[0006] Secondly, during placement, its lateral position on the conveyor belt needs to be manually adjusted multiple times to ensure that the pusher on the conveyor belt evenly contacts the pallet and drives it to run smoothly. Improper adjustment can easily lead to uneven force on the pusher, causing the pallet to tilt, jam, or even damage the conveyor belt. In terms of strength, the pallet structure design is not adapted to the requirements of the flipping operation. During the horizontal-vertical flipping process, it needs to withstand the gravitational torque generated by the weight of the copper ingot, and at the same time, it will collide and impact with the inner wall of the material trough of the feeding mechanism. Due to insufficient structural strength and poor stability, it is very easy for the structure to fall apart, causing the pallet to be scrapped. It may also cause the copper ingot to fall, causing accidents such as equipment jamming and production interruption.

[0007] Third, the existing pallets lack a strapping positioning structure. After the copper ingot is installed and fixed on the pallet, the operator needs to manually determine the position of the strapping based on experience. Only through repeated measurement, marking and adjustment can the strapping be ensured to be in a reasonable position to ensure the packing is secure (position deviation can easily lead to loose connection between the copper ingot and the pallet, displacement during flipping, and uneven spacing can easily cause excessive local stress and breakage of the strapping). This process not only takes up a lot of time, but is also greatly affected by the operator's experience, resulting in poor packing quality stability and significantly reducing overall work efficiency. Summary of the Invention

[0008] The present invention aims to at least partially solve one of the technical problems in the related art.

[0041] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0043] 1. Simplify the assembly process and reduce operating costs: The rectangular plug-in structure (first rectangular plug-in hole and first rectangular plug-in part, second rectangular plug-in hole and second rectangular plug-in part) allows each module to be quickly positioned and spliced ​​without repeated alignment and adjustment, greatly shortening the assembly time. The overall fixation is achieved through the threaded connection between the connecting screw and the connecting screw barrel, reducing the amount of screws used and avoiding the mixing of ordinary screws into the copper ingot after being burned at high temperature, thus reducing the risk of smelting impurities.

[0044] 2. Precise positioning to avoid operational hazards: The triangular notches are consistent in number and position with the pushers, which can quickly position the pallet in the lateral position of the conveyor belt without the need for repeated manual adjustments. This ensures that the pushers are evenly stressed, thereby avoiding problems such as pallet tilting, jamming, and damage to the conveyor belt from the root, and ensuring a smooth and efficient conveying process.

[0045] 3. Adaptable to deformable pushers, improving equipment fault tolerance: Through the detachable and reversible adjustment seat structure, or the non-disassembly-required rotating irregular turntable structure, it can quickly adapt to pushers that are deformed by collision. The switching between the notched part and the flat part can be achieved with simple operation, ensuring that all pusher mating surfaces are coplanar. There is no need to replace large components such as the bottom frame, effectively solving the problem of pallet running deviation caused by pusher deformation, and greatly improving the equipment's adaptability to working conditions.

[0046] 4. Convenient and efficient maintenance, reducing operating costs: The disassembly and reversal of the adjustment seat only requires three steps: unlocking and fixing, pulling and turning, and relocking. Irregular turntables do not need to be disassembled; the state can be switched by pulling and rotating, which greatly simplifies the maintenance process and improves maintenance efficiency. There is no need to replace large parts, which reduces spare parts consumption and maintenance costs, while improving the continuity of equipment operation.

[0047] 5. Improve the stability of flipping and avoid safety hazards: The outer side of the positioning plate is equipped with cross-grid reinforcing ribs. The middle solid plate, side support plate and edge support plate are connected to the spacer through the slot and resist the limit. The overall structural strength is adapted to the horizontal-vertical flipping conditions. It can withstand the weight of the copper disc and the impact of collision, prevent the structure from falling apart or the copper disc from falling, and ensure the continuity of production.

[0048] 6. Standardize packaging operations and improve work efficiency and quality: The first positioning groove of the spacer plate and the third positioning groove of the middle support plate, side support plate and edge support plate are set in a cross shape, which provides precise positioning and limit for the packing strap. No manual experience judgment or repeated measurement is required, avoiding problems such as loose connection or breakage caused by packing strap skewing or uneven spacing. The inner wall of the positioning groove is equipped with a serrated anti-slip texture to enhance the friction between the packing strap and the pallet, further improving the packaging firmness and ensuring that the copper ingot does not shift during the flipping process, which significantly improves the stability of packaging quality and overall work efficiency.

[0049] 7. Optimized functional design to meet actual working conditions: The partition is equipped with slanted lifting channels and upper guides to facilitate the threading and positioning of lifting ropes, reduce frictional wear of the lifting ropes, and improve the ease of lifting; the central solid plate, side support plate, and edge support plate are provided with array-shaped circular weight-reducing holes to reduce the self-weight of the pallet while ensuring structural strength, without affecting the load-bearing capacity; wooden washers of appropriate size are preset at the contact points between the connecting bolt and each plate; through the precise fit of the washers with the bolt and the countersunk hole, the alignment of the connecting bolt axis with the countersunk hole axis of the plate is ensured from the assembly starting point, laying the foundation for the smooth threading and precise thread connection of the subsequent connecting bolts. At the same time, the wooden washers can fill the gaps between components from the source to form an initial sealing structure, and their material properties can buffer the vibration and impact during assembly and use, avoiding direct contact and friction between the connecting bolt and each metal plate, reducing component wear from the root, extending the overall service life of the pallet, and meeting the working conditions of copper smelting and transportation;

[0050] 8. Facilitating production optimization and ensuring process implementation: This pallet is perfectly suited to the production solution of "copper ingots being packaged and then loaded onto the scrap handling machine". Through stable and efficient transportation, it further revitalizes the stockpiled copper ingot resources and makes up for the supply gap of cold copper. At the same time, it avoids the environmental and safety risks of traditional direct-feeding processes, providing strong support for the continuity and compliance of copper smelting production.

[0067] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0068] The following description, in conjunction with the accompanying drawings, describes a tray for loading waste onto a machine according to an embodiment of the present invention.

[0069] like Figures 1-8 As shown, the tray for loading waste onto the machine according to an embodiment of the present invention includes:

[0070] The base frame 1 includes a middle base frame 11 and side base frames 12 symmetrically and oppositely arranged on the outside of the middle base frame 11. The bottom recesses of the middle base frame 11 and the side base frames 12 are provided with connecting screws 13. One end of the connecting screws 13 passes through the top of the middle base frame 11 and the side base frames 12 respectively. The outer surfaces of the two sets of side base frames 12 are evenly provided with notches 14 that are adapted to the upper conveyor chain pusher. The inner surfaces of the two sets of side base frames 12 are connected to the middle base frame 11 through spacer plates 15. The bottom of the spacer plates 15 is provided with a first positioning groove 151.

[0071] Spacer 2: evenly distributed on the top of the middle base frame 11 and the side base frame 12, and sleeved on the outside of the connecting screw cylinder 13;

[0072] Top frame 3: includes positioning outer plates 31 symmetrically and oppositely arranged on the top of partition 2. The second positioning grooves 311 on the inner side of the two sets of positioning outer plates 31 enclose the inner plate placement part 100. The inner plate placement part 100 is provided with a middle solid plate 32, a side support plate 33 and a side support plate 34 in sequence from the inside to the outside, and is snapped and fixed to the top of partition 2. The positioning outer plates 31, the middle solid plate 32 and the side support plate 34 are all sleeved on the outside of the connecting screw cylinder 13. The bottom of the middle solid plate 32, the side support plate 33 and the side support plate 34 are symmetrically provided with a third positioning groove 200.

[0073] Connecting screw 4: It is respectively set on the inner wall of the countersunk hole 300 at the top of the positioning outer plate 31, the middle solid plate 32 and the side support plate 34, and is threaded to the inner wall of the connecting screw cylinder 13.

[0074] It should be noted that the connecting screw barrel 13 and connecting screw 4 described in this example are designed as a set. There are nine sets of both connecting screw barrel 13 and connecting screw 4. The connecting screw barrel 13 and connecting screw 4 are both made of SUH661 heat-resistant steel, which has a melting point of 1450-1510℃, higher than the normal blowing temperature and peak reaction temperature of the copper converter. This can prevent the components from melting and avoid them from dissolving into the copper liquid, causing compositional imbalance. It also facilitates the recovery of the components by screening during copper liquid treatment.

[0075] It should also be noted that, except for the connecting screw cylinder 13 and the connecting screw 4, the pallet of the present invention is made of wood.

[0076] Specifically, the pallet of the present invention forms a complete load-bearing structure through modular assembly, and, in conjunction with the residual conveying and flipping process, enables the safe transfer of copper ingots.

[0077] Its assembly principle is as follows:

[0078] 1. Assembly of base frame 1: Connect the middle base frame 11 and the side base frame 12 through the rectangular plug-in structure of the spacer plate 15. After adjusting the spacing, insert the connecting screw 13 so that the connecting screw 13 passes through the connecting hole 153 of the middle base frame 11, the side base frame 12 and the spacer plate 15 to complete the positioning of the base frame 1.

[0079] 2. Installation of spacer 2: Three sets of spacers 2 are fitted on the outside of the connecting screw cylinder 13 and laid flat on the top of the bottom frame 1. The two sets of spacers 2 on the outside are used to position the installation of the outer plate 31, and the one set of spacers 2 in the middle is used for the locking and limiting of the middle fixed plate 32, the side support plate 33, and the side support plate 34.

[0080] 3. Assembly of top frame 3: First, the middle solid plate 32, side support plate 33, and side support plate 34 are spliced ​​with the second rectangular insertion hole 3110 of the positioning outer plate 31 through the second rectangular insertion part 400 to form the top frame 3 module. Then, the top frame 3 is sleeved on the outside of the connecting screw cylinder 13 and fixed by the lower slot 500 and the middle set of spacers 2.

[0081] 4. Overall fixing: Insert the connecting screw 4 into the countersunk hole 300 at the top of the top frame 3 and thread it into the inner wall of the connecting screw cylinder 13 to achieve tight fixing of the bottom frame 1, the partition seat 2, and the top frame 3, thus completing the overall assembly of the pallet.

[0082] Its packaging and positioning principle is as follows:

[0083] After the copper ingot is placed on top of the top frame 3 and wrapped with packaging film, the packing strap can be laid crosswise along the first positioning groove 151 (horizontal) of the spacer plate 15 and the third positioning groove 200 (longitudinal) of the middle support plate 32, the side support plate 33, and the side support plate 34. The width and depth of the first positioning groove 151 and the third positioning groove 200 are adapted to the size of the conventional packing strap. The serrated anti-slip texture on the inner wall of the groove increases the friction between the packing strap and the groove wall, ensuring that the position of the packing strap is fixed and realizing the firm binding of the copper ingot and the pallet.

[0084] Its transportation and transfer principles are as follows:

[0085] 1. A lifting rope is threaded through the inclined lifting channel 21 of the two outer sets of spacers 2. The upper guide part 211 at the port of the inclined lifting channel 21 guides the lifting rope to an upward angle and reduces friction loss. Then the tray with the copper ingot is lifted to the top of the conveyor belt of the upper machine.

[0086] 2. When lowering the pallet, the notch 14 of the side base frame 12 is aligned with the pusher of the conveyor belt. The arc transition section 141 at the edge of the notch 14 prevents the pusher from rubbing against the side base frame 12, thus achieving lateral positioning of the pallet. After the pusher abuts against the inner wall of the notch 14, it drives the pallet to move along the conveyor belt.

[0087] 3. The pallet is conveyed to the upper loading mechanism by the conveyor chain. The loading mechanism flips the pallet and the copper ingot together from a horizontal state to a vertical state. The reinforcing ribs 312 on the outer side of the positioning outer plate 31 enhance the impact resistance of the top frame 3. The copper ingot remains stable under the joint restraint of the packing strap and the pallet, and is finally put into the converter to complete the smelting. At the same time, the circular weight reduction holes 600 of the middle solid plate 32, side support plate 33 and side support plate 34 reduce the self-weight of the pallet and reduce the energy consumption during the conveying and flipping process.

[0088] In one embodiment of the present invention, such as Figures 1-8 As shown, the notch 14 is triangular, and its number is equal to the number of pushers of the upper conveyor chain, and their positions correspond one-to-one.

[0089] The inner diameter of the notch 14 gradually decreases from the outer surface of the side base 12 to the inner surface;

[0090] An arc transition section 141 is integrally formed on the outer surface of the side base frame 12 at the edge of the notch 14, and the radius of the arc transition section 141 is 2-3mm.

[0091] Specifically, the triangular notch 14 is the same in number and position as the pusher, which can quickly position the pallet in the lateral position of the conveyor belt, ensure that the pusher is evenly stressed, and avoid the pallet tilting or jamming. The inner diameter is reduced from the outside to the inside, which can fit the shape of the pusher, enhance the contact stability between the pusher and the notch 14, and improve the drive reliability. The 2-3mm radius arc transition section 141 can prevent the pusher from rubbing against the side base frame 12, reduce component wear, and extend service life.

[0092] In one embodiment of the present invention, such as Figures 1-8 As shown, an opening slot 5 is provided on the surface of the side base frame 12 and at the corresponding position of the notch 14. An adjustment seat 52 is horizontally slidably connected to the inner wall of the horizontal sliding groove 51 of the opening slot 5. The outer end face of the adjustment seat 52 is on the same horizontal plane as the surface of the side base frame 12. A preset distance is spaced between the inner end face of the adjustment seat 52 and the inner wall of the horizontal sliding groove 51.

[0093] A notch 14 is formed on the outer end face of the adjusting seat 52, and an arc transition section 141 is integrally formed on the outer end face of the adjusting seat 52 at the edge of the notch 14.

[0094] The adjusting seat 52 has a straight section at the end away from the notch 14;

[0095] The top of the adjusting seat 52 is symmetrically provided with weight-reducing finger grooves 53, which are located outside the notch 14;

[0096] The top of the adjusting seat 52 is symmetrically provided with fixing column holes 54, which are located outside the weight reduction finger groove 53;

[0097] The top of the side base frame 12 is symmetrically provided with fixing bolts 55, which correspond to the positions of fixing column holes 54. One end of the fixing bolt 55 passes through the interior of the horizontal slide groove 51 and is threaded to the inner wall of the fixing column hole 54. The bottom wall of the horizontal slide groove 51 is provided with elastic clips 56 at the positions corresponding to the fixing column hole 54, which are engaged and fixed to the fixing column hole 54.

[0098] The bottom of the adjusting seat 52 is symmetrically provided with inclined guides 57, which correspond to the position of the elastic clip 56.

[0099] It should be noted that the fixing bolt 55 and the elastic clip 56 described in this example are both made of copper.

[0100] Specifically, during actual use, the pusher is prone to deformation due to collisions and impacts. The deformed pusher cannot accurately and synchronously insert into the notch 14 with other undeformed pushers. This deformed pusher directly affects the force balance and movement trajectory of the support, causing the support to be unable to move accurately according to the preset position. To fundamentally solve this problem, the present invention has specially designed a bidirectional switchable adjustment seat 52 structure. The deformation of the pusher can be adapted and compensated through a simple disassembly and reversal operation. The specific operation process is as follows:

[0101] Unlocking and fixing: When the push frame deforms, first loosen the fixing bolts 55 on the side base frame 12 to release the threaded fixing constraint;

[0102] Disassembling the adjustment seat 52: The operator inserts his finger into the weight-reducing finger groove 53 and applies a pulling force outward. When the pulling force is greater than the elastic force of the elastic clip 56, the elastic clip 56 disengages from the fixing post hole 54, and the adjustment seat 52 can be pulled out from the horizontal slide groove 51.

[0103] Reversing Assembly: Reversing the disassembled adjusting seat 52 so that the end with the original notch 14 is inserted into the horizontal slide groove 51. The bottom inclined guide 57 is used to assist in the assembly. When the elastic clip 56 engages with the fixing post hole 54 again, it indicates that the adjusting seat 52 has reached the preset installation position. At this time, the straight part of the adjusting seat 52 is flush with the inner wall of the tip of the notch 14 of other unadjusted adjusting seats 52, ensuring that all mating surfaces are coplanar and ensuring the accuracy of the support's travel trajectory.

[0104] Locking and fixing: Finally, tighten the fixing bolt 55 to complete the position locking of the adjusting seat 52 through the double fixing of threaded connection and elastic snap-fit.

[0105] Through the above structural design and adjustment method, the deformation pusher can be adapted and compensated with simple disassembly and assembly operations, without the need to replace the entire side base frame 12 structure, which significantly improves the fault tolerance and maintenance convenience of the equipment. Through the notch-straight bidirectional structural design of the adjustment seat 52, an efficient adaptation solution is provided for the collision deformation problem of the pusher. The entire operation only requires three core steps: loosening the bolts, pulling and turning, and re-fixing. There is no need to replace large components such as the side base frame 12. While ensuring the travel accuracy of the support, the maintenance efficiency and fault tolerance of the equipment are greatly improved.

[0106] In one embodiment of the present invention, such as Figures 1-8 As shown, the inner wall of the opening groove 5 is provided with a disc groove 61, and an irregular turntable 62 is slidably connected to the inner wall of the disc groove 61.

[0107] The bottom central shaft of the irregular turntable 62 is vertically slidably connected to the inner wall of the central hole of the disc groove 61, and a return spring 63 is fixedly connected between the turntable 62 and the inner wall of the central hole.

[0108] The notch 14 is formed on the arc-shaped surface of the irregular turntable 62, and the outer end face of the irregular turntable 62 is integrally formed with an arc transition section 141 at the edge of the notch 14;

[0109] The irregular turntable 62 has a straight section at the end away from the notch 14;

[0110] The irregular turntable 62 has a grip plate 64 at the top and a positioning shaft 65 symmetrically arranged at the bottom. The inner wall of the groove 61 has four sets of positioning holes 66, which are respectively matched with the corresponding positions of the positioning shaft 65 on the inner wall of the groove 61 before and after the irregular turntable 62 rotates.

[0111] It should be noted that the reset spring 63 described in this example is made of copper.

[0112] Specifically, the core improvement of this embodiment lies in solving the adaptation lag problem caused by the unpredictable position of the deformable pusher: In actual working conditions, the collision deformation of the pusher is random, and it is impossible to determine the specific position of the deformable pusher in advance. Traditional adjustment structures require first locating the deformation position and then disassembling and adjusting, which is inefficient and easily affects the continuity of work. To address this pain point, this invention uses a rotary quick adjustment structure of irregular turntable 62 to achieve instant adaptation of the deformation position, and can complete the state switching without disassembly and assembly. The specific operation process is as follows:

[0113] Unlock positioning: Pull the grip 64 upwards. The grip 64 simultaneously drives the irregular turntable 62 and the bottom central shaft to move vertically upwards along the center hole of the groove 61. During this process, the reset spring 63 is stretched and stored. At the same time, the positioning shaft 65 at the bottom of the irregular turntable 62 disengages from the current positioning hole 66, releasing the angle lock.

[0114] Rotation adjustment: While holding the handle 64 in the upward position, rotate the irregular turntable 62 to turn the flat part that was originally facing inward to the outward until the flat part is flush with the inner wall of the tip of the notch 14 in other unadjusted positions, ensuring that all push frame mating surfaces are coplanar and ensuring the accurate travel trajectory of the support.

[0115] Reset and lock: When the irregular turntable 62 rotates to the target angle, the positioning shaft 65 is just aligned with the positioning hole 66 at the corresponding position. At this time, release the grip 64, and the return spring 63 will drive the irregular turntable 62 and the positioning shaft 65 to move down synchronously under the action of elastic force. The positioning shaft 65 is inserted into the positioning hole 66 to complete the double locking of angle and position, and the adjustment process is completed.

[0116] Through the above structural design and adjustment method, the deformation pusher can be adapted and compensated simply by rotating the irregular turntable 62, without the need to disassemble and adjust the adjustment seat 52, which significantly improves the fault tolerance and maintenance convenience of the equipment.

[0117] In one embodiment of the present invention, such as Figures 1-8 As shown, the spacer plate 15 is vertically connected to the middle base frame 11 and the side base frame 12 respectively. The top of the spacer plate 15 is on the same horizontal plane as the top of the middle base frame 11 and the side base frame 12 respectively. The surface of the middle base frame 11 and the surface of the spacer plate 15 are respectively provided with a first rectangular insertion hole 111 and a first rectangular insertion part 152. The first rectangular insertion part 152 is inserted into the first rectangular insertion hole 111 and slides with the inner wall of the first rectangular insertion hole 111. The surface of the first rectangular insertion part 152 is provided with a connecting hole 153 communicating with the recessed hole. The connecting screw 13 passes through the connecting hole 153.

[0118] The surfaces of the central support plate 32, the side support plate 33 and the side support plate 34 are respectively provided with a second rectangular insertion part 400 and a second rectangular insertion hole 3110 at positions corresponding to the inner wall of the second positioning groove 311. The second rectangular insertion part 400 is inserted into the second rectangular insertion hole 3110 and slides in cooperation with the inner wall of the second rectangular insertion hole 3110.

[0119] It should be noted that both the first rectangular insertion part 152 and the second rectangular insertion part 400 described in this embodiment are provided with tapered guide parts (not shown in the figure) on their end faces. The tapered guide parts guide the insertion parts and the insertion holes to be quickly aligned from the assembly starting point through the gradually changing inclined surface structure at the end, avoiding hard collisions caused by positional deviations during insertion. At the same time, it can reduce the resistance during the insertion process, and the components can be smoothly spliced ​​without repeated adjustments. This not only reduces the difficulty of operation and improves the assembly efficiency, but also protects the edges of the insertion parts and insertion holes from the source, preventing structural damage caused by collisions and extending the service life of the components.

[0120] Specifically, the spacer plate 15 vertically connects the middle base frame 11 and the side base frame 12 and is flush with the top, which can accurately fix the distance between the two and ensure the flatness of the bottom frame 1, avoiding the impact of height difference on the installation of subsequent components after assembly. The first rectangular plug part 152 slides with the first rectangular plug hole 111 to realize the rapid splicing of the bottom frame 1 module. The connecting hole 153 allows the connecting screw cylinder 13 to pass through, further strengthening the structural stability of the bottom frame 1. The second rectangular plug-in cooperation between the middle solid plate 32, the side support plate 33, the side support plate 34 and the positioning outer plate 31 can quickly position the position of each plate of the top frame 3, ensuring accurate assembly, enhancing the overall firmness of the top frame 3, and preventing the plate from shifting during use. The plug part is provided with a conical guide part, which can guide the plug part to quickly align and enter the plug hole, reducing collision loss during plugging, further improving assembly efficiency and reducing operation difficulty.

[0121] In one embodiment of the present invention, such as Figures 1-8 As shown, there are three sets of spacers 2, all located on one side of the top of the spacer plate 15 and parallel to each other.

[0122] The outer two sets of partitions 2 are symmetrically and oppositely provided with inclined hanging channels 21, and the ends of the inclined hanging channels 21 are integrally formed with upper guide parts 211.

[0123] Specifically, the three sets of partition seats 2 are arranged parallel to each other on the top of the spacer plate 15, which can provide stable support for the top frame 3, clarify the installation position of each plate, ensure the flatness and firmness of the connection between the upper and lower structures of the pallet, and prevent the top frame 3 from shifting under force. The inclined lifting channels 21 of the two outer sets of partition seats 2 facilitate the threading of lifting ropes to meet the lifting needs of the pallet and copper ingots. The upper guide part 211 at the port can guide the angle of the lifting rope, reduce the friction loss between the lifting rope and the edge of the channel, and at the same time assist the lifting rope to quickly position itself, improving the convenience and safety of the lifting operation.

[0124] In one embodiment of the present invention, such as Figures 1-8 As shown, the two sets of positioning outer plates 31 are respectively located on the top of the two sets of outer partitions 2. The middle fixed plate 32, the side support plate 33 and the side support plate 34 are all snapped and fixed on the top of the middle set of partitions 2, and abut against and limit the movement of the two sets of outer partitions 2. The bottom of the middle fixed plate 32, the side support plate 33 and the side support plate 34 are all provided with a lower slot 500 at the corresponding position of the top of the middle set of partitions 2.

[0125] Specifically, the outer positioning plate 31 is installed corresponding to the outer partition 2. The middle fixing plate 32, side support plate 33, and side support plate 34 are snapped into the middle partition 2 and abut against the outer partition 2. Through partition support and abutment limit, the position of each plate of the top frame 3 is clearly defined to avoid assembly offset and ensure the overall structure of the top frame 3 is regular. The bottom slot 500 of the middle fixing plate 32 and other plates is adapted to the middle partition 2 to enhance the snapping firmness and prevent the plates from loosening and shifting during pallet flipping and transportation. At the same time, the abutment limit further enhances the impact resistance of the top frame 3 and adapts to the force requirements of copper ingot transfer.

[0126] In one embodiment of the present invention, such as Figures 1-8 As shown, the first positioning groove 151 and the third positioning groove 200 are arranged in a cross-shaped structure. The groove width of the first positioning groove 151 and the third positioning groove 200 is 5-10mm, the groove depth is 3-5mm, and the inner wall of the groove is provided with anti-slip texture, which is a serrated protrusion arranged at intervals.

[0127] Specifically, the first positioning groove 151 and the third positioning groove 200, which intersect each other, can provide precise positioning for the strapping in both the horizontal and vertical directions, eliminating the need for manual adjustment based on experience. This avoids the strapping from being skewed or unevenly spaced, ensuring that the copper ingot is firmly bound to the pallet and adapting to the needs of flipping and transfer. The size design of 5-10mm groove width and 3-5mm groove depth can accommodate conventional strapping specifications, ensuring stable embedding of the strapping. The serrated raised anti-slip texture can increase the friction between the strapping and the groove wall, preventing the strapping from shifting during conveying and flipping, further improving the reliability of the packaging and reducing the risk of the copper ingot falling off.

[0128] In one embodiment of the present invention, such as Figures 1-8 As shown, the outer surface of the positioning outer plate 31 is provided with reinforcing ribs 312. The reinforcing ribs 312 are distributed in a cross grid pattern. The height of the reinforcing ribs 312 is the same as the height of the positioning outer plate 31. The reinforcing ribs 312 and the positioning outer plate 31 are integrally formed.

[0129] The top of the central solid plate 32, the side support plate 33 and the edge support plate 34 are all provided with circular weight reduction holes 600;

[0130] The circular weight-reducing holes 600 are non-through holes with a diameter of 10-15mm. The circular weight-reducing holes 600 on the same board are distributed in an array, and the total area of ​​the circular weight-reducing holes 600 does not exceed one-fifth of the surface area of ​​the board.

[0131] Specifically, the forked mesh reinforcing ribs 312 can significantly enhance the structural strength and deformation resistance of the positioning outer plate 31. Especially when the pallet is flipped, it can effectively resist the impact of the copper disc's gravitational torque and the feeding mechanism, preventing the positioning outer plate 31 from bending and being damaged. The height of the reinforcing ribs 312 is consistent with that of the positioning outer plate 31, which can evenly distribute external forces and ensure that the positioning outer plate 31 is subjected to balanced forces, further improving the stability of the top frame 3. The one-piece molding structure eliminates additional assembly steps, ensuring the firmness of the connection between the reinforcing ribs 312 and the positioning outer plate 31, preventing them from falling off during use, and simplifying the production process and improving manufacturing efficiency.

[0132] The circular weight-reduction holes 600 reduce the weight of the central support plate 32, side support plate 33, and edge support plate 34 while ensuring the structural strength of the plate, thereby reducing the overall weight of the pallet and reducing energy consumption during transportation and flipping. It also facilitates manual handling. The non-through hole design avoids the reduction in load-bearing capacity caused by holes penetrating the plate. The 10-15mm hole diameter and array distribution can evenly distribute the weight-reduction area and prevent local stress concentration. The total area of ​​the circular weight-reduction holes 600 does not exceed one-fifth of the plate surface area, strictly controlling the weight reduction ratio to ensure that the plate can still stably bear the weight of the copper ingot and adapt to the stress requirements of pallet transportation.

[0133] In one embodiment of the present invention, such as Figures 1-8 As shown, wooden washers 131 are fitted at the contact points between the outer wall of the connecting screw cylinder 13 and the middle base frame 11, side base frame 12, spacer 2, positioning outer plate 31, middle solid plate 32 and side support plate 34. The thickness of the wooden washers 131 is 3-4mm, and the inner diameter of the washers is adapted to the outer diameter of the connecting screw cylinder 13, and the outer diameter is consistent with the inner diameter of the countersunk hole of the corresponding plate.

[0134] Specifically, the wooden washer 131 is adapted to the size of the countersunk holes of the connecting screw 13 and each plate, and can fill the contact gap between the two to prevent loosening between components after assembly, thereby improving the connection tightness of the overall pallet structure. The 3-4mm thick wooden washer 131 can buffer the vibration and collision during pallet transportation and flipping, reduce the wear caused by direct contact between metal parts (connecting screw 13 and each plate), and extend the service life of the parts. The wooden material has a certain degree of elasticity and stability, which can help to disperse the force on the connection part, prevent local stress concentration from causing plate deformation, and avoid the problem of metal washers sticking together under high temperature conditions, thus meeting the requirements of copper smelting conditions.

[0135] In summary, the pallet for loading onto the machine according to the embodiments of the present invention simplifies the assembly process, reduces screw costs, improves conveying and turning stability through positioning with notch 14 and reinforcement with reinforcing ribs 312, avoids safety hazards, standardizes packaging with cross-shaped positioning grooves, and improves efficiency and quality; it also features inclined lifting channels 21, circular weight reduction holes 600, and wooden washers 131 to adapt to working conditions, reduce losses and energy consumption, and ensure smelting purity.
