Technical Field
[0001] The present invention relates to the technical field of transportation equipment for plastic alloy heat treatment processing, and specifically provides a transportation equipment for plastic alloy heat treatment processing. Background Art
[0002] In the plastic alloy heat treatment processing flow, from the pretreatment of raw materials, heating and temperature rising, heat preservation and modification to cooling and shaping, it needs to go through multiple continuous processes, and each process usually flows between different processing equipment or workstations. In this process, as the core link connecting each heat treatment process, the efficiency and stability of the transportation link have crucial impacts on the overall production rhythm, product quality control and safety production.
[0003] However, most of the existing transportation equipment for plastic alloy heat treatment processing are ordinary tools such as trolleys, which have few functions, and there is no specific device for clamping and fixing plastic alloy heat treatment workpieces during transportation. As a result, there is a risk that the relatively smooth-shaped plastic alloy heat treatment workpieces will fall off during transportation, causing damage to the plastic alloy heat treatment workpieces. Summary of the Invention

Universal wheels are fixed to the bottom surface of the bottom plate. A telescopic rod is fixed to the upper surface of the bottom plate. A placement box is fixed to the end of the telescopic rod far from the bottom plate. An opening is fixed to the side wall of the placement box. A drawer penetrates through the side wall of the placement box and is slidably connected at the penetration point. The outer wall of the drawer fits with the inner wall of the opening on the side wall of the placement box. A handle is fixedly connected to the side wall of the placement box. Above the placement box, there is a fixing device for conveniently clamping plastic alloy heat treatment workpieces, and above the placement box, there is a loading and unloading device for conveniently loading and unloading plastic alloy heat treatment workpieces; Among them, the fixing device includes a guide groove, a clamping plate, a hanging plate, a receiving plate, a pull rod, a connecting plate and a push plate.

A protrusion is fixed to the bottom surface of the clamping plate. The outer wall of the protrusion at the bottom surface of the clamping plate is slidably connected to the inner wall of the guide groove.
[0006] According to the above technical solution, the hanging plate is hinged to the side wall of the clamping plate near the center of the placement box. The clamping plate and the hanging plate are each provided with two sets. The two ends of the receiving plate are respectively hinged to the end of the hanging plate away from the clamping plate. When the clamping plates approach each other, the receiving plate is pushed downward by the hanging plate.
[0007] According to the above technical solution, the pull rod is hinged to the side wall of the clamping plate near the handle. Two sets of pull rods are also provided. The two ends of the connecting plate are respectively hinged to the end of the pull rod away from the clamping plate. The push plate is fixedly connected to the front of the connecting plate. When the clamping plates approach each other, the pull rod drives the connecting plate to push the push plate forward.
[0008] According to the above technical solution, the loading and unloading device includes a guide plate, a fixed rod, a sliding block and a limiting plate. The guide plate is hinged to the end of the receiving plate away from the handle. The fixed rod is fixedly connected to the upper surface of the placement box. When the receiving plate moves up and down, it drives the guide plate to rotate.
[0009] According to the above technical solution, the sliding block is hinged to the end of the fixed rod away from the placement box, the end of the sliding block away from the fixed rod is slidably connected to the side wall of the guide plate, the limiting plate is fixedly connected to the upper surface of the placement box, and the guide plate rotates around the upper end of the fixed rod through the sliding block when it rotates.
[0010] According to the above technical solution, an auxiliary device for protecting the heat-treated plastic alloy parts is provided on the side of the placement box. The auxiliary device includes a hinge rod, a sliding plate, a strong spring, and a baffle. The hinge rod is hinged to the side wall of the clamping plate away from the hanging plate. When the clamping plate slides, it drives the hinge rod to rotate.
[0011] According to the above technical solution, the side wall of the limiting plate is provided with a groove, the side wall of the hinge rod is in contact with the inner wall of the groove, the sliding plate is slidably connected to the side wall of the placement box, and the end of the hinge rod away from the clamping plate is hinged to the upper surface of the sliding plate.

[0012] According to the above technical solution, one end of the strong spring is slidably connected to the bottom surface of the sliding plate, the telescopic rod passes through the baffle and is fixedly connected at the point of penetration, and the other end of the strong spring is fixedly connected to the upper surface of the baffle. When the sliding plate slides up and down, it compresses and stretches the strong spring.
[0013] This invention provides a transport device for heat treatment processing of plastic alloys. It has the following beneficial effects: 1. This invention includes a fixing device. When loading heat-treated plastic alloy parts, the guide groove, hanging plate, and receiving plate work together to push two sets of clamping plates closer together, clamping the heat-treated plastic alloy parts above the receiving plate. This prevents the heat-treated plastic alloy parts from falling from the side during transportation, thus avoiding damage and solving the problem of difficulty in fixing them during transportation. After transportation, when unloading the heat-treated plastic alloy parts, the pull rod, connecting plate, and push plate work together to push the parts forward, allowing workers to unload them more quickly and improving work efficiency. This also solves the problem that the heat-treated plastic alloy parts may be at high temperatures, requiring workers to manually remove tools for unloading, which is cumbersome.
[0014] 2. This invention includes a loading and unloading device. During loading and transportation of heat-treated plastic alloy parts, a guide plate, a fixing rod, and a sliding block limit the movement of the parts, preventing them from being squeezed together on the receiving plate and causing them to fall off. This solves the problem of parts of different shapes potentially squeezing each other and falling off during loading. During unloading, the guide plate, fixing rod, and sliding block allow the parts to slide slowly off the guide plate, preventing them from falling directly off the equipment and causing damage. Simultaneously, the limiting plate restricts the sliding range of the clamping plates, preventing excessive sliding distance when the clamping plates move away from each other, which could cause the receiving plate to move upwards too quickly, throwing the parts and damaging them. This solves the problem of parts falling too quickly during unloading and causing damage.
[0015] 3. This invention includes an auxiliary device. During the transportation of heat-treated plastic alloy parts, the device, in conjunction with the hinge rod, sliding plate, strong spring, and baffle, applies a pushing force to the clamping plate, making the clamping of the heat-treated plastic alloy parts more stable. This prevents the clamping plate from failing to stably hold the heat-treated plastic alloy parts due to inertia during transportation, which is caused by the large mass of the parts. This solves the problem of reduced clamping effectiveness when the mass of the heat-treated plastic alloy parts is too large. During the unloading of the heat-treated plastic alloy parts, the device, in conjunction with the hinge rod, sliding plate, strong spring, and baffle, applies a pulling force to the clamping plate, pulling the clamping plates apart. This prevents the heavy heat-treated plastic alloy parts above the receiving plate from being difficult to lift, solving the problem of difficulty in automatically unloading heavy heat-treated plastic alloy parts.

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-7One embodiment of the present invention is as follows: a transport device for heat-treated plastic alloy parts includes a base plate 1. When transporting heat-treated plastic alloy parts, tools are used to place the parts with lower temperatures on top of the base plate 1. A caster wheel 2 is fixed to the bottom surface of the base plate 1, and a telescopic rod 3 is fixed to the upper surface of the base plate 1. A placement box 4 is fixed to the end of the telescopic rod 3 away from the base plate 1. The placement box 4 moves downwards to retract the telescopic rod 3. After moving downwards, the placement box 4 limits the movement of the heat-treated plastic alloy parts with lower temperatures above the base plate 1. An opening is fixed to the side wall of the placement box 4, and a drawer 5 penetrates the side wall of the placement box 4, with a sliding connection at the penetration point. Next, the outer wall of drawer 5 fits against the inner wall of the opening of the side wall of the storage box 4. After placing the heat-treated plastic alloy parts to be transported, drawer 5 is opened and tools are placed inside to prevent tools from being lost. Handle 6 is fixedly connected to the side wall of storage box 4. After loading the heat-treated plastic alloy parts with lower temperatures, handle 6 is pushed down, and handle 6 moves storage box 4 downward. A fixing device is provided on the top of storage box 4 to facilitate clamping the heat-treated plastic alloy parts. Heat-treated plastic alloy parts with higher temperatures are placed in the fixing device on the top of storage box 4. The heat-treated plastic alloy parts with different processing degrees are classified, stored and transported.
[0020] The fixing device includes a guide groove 71, a clamping plate 72, a hanging plate 73, a receiving plate 74, a pull rod 75, a connecting plate 76, and a push plate 77. The guide groove 71 is formed on the upper surface of the placement box 4. The clamping plate 72 is slidably connected to the upper surface of the placement box 4. A protrusion is fixed on the bottom surface of the clamping plate 72. The outer wall of the protrusion on the bottom surface of the clamping plate 72 is slidably connected to the inner wall of the guide groove 71. The hanging plate 73 is hinged to the side wall of the clamping plate 72 near the center of the placement box 4. Two sets of clamping plates 72 and hanging plates 73 are provided respectively. The two ends of the receiving plate 74 are respectively hinged to the ends of the hanging plate 73 away from the clamping plate 72. The pull rod 75 is hinged. On the side wall of clamping plate 72 near handle 6, when the two sets of clamping plates 72 approach each other, the hinge points of clamping plates 72 and pull rod 75 also approach each other. Pull rod 75 is also provided in two sets. The two ends of connecting plate 76 are respectively hinged to the ends of pull rod 75 away from clamping plate 72. When the hinge points of the two sets of clamping plates 72 and pull rod 75 approach each other, pull rod 75 itself also rotates. The rotation of pull rod 75 pushes connecting plate 76 to move away from bearing plate 74. Push plate 77 is fixedly connected to the front of connecting plate 76. When connecting plate 76 moves away from bearing plate 74, it also drives push plate 77 to move together. The push plate 77 moves away from the heat-treated plastic alloy workpiece. When unloading is required, the handle 6 is pulled upwards, causing the placement box 4 to move upwards as well. As the placement box 4 moves upwards, the two sets of clamping plates 72 are pulled away from each other by the loading and unloading device and auxiliary device. When the two sets of clamping plates 72 move away from each other, the hanging plate 73 rotates. The rotation of the hanging plate 73 causes the receiving plate 74 to move upwards, lifting the heat-treated plastic alloy workpiece. When the two sets of clamping plates 72 move away from each other, the pull rod 75 also rotates, pulling the connecting plate 76 towards the bearing plate. The connecting plate 74 moves in the direction of the connecting plate 76, which drives the push plate 77 to push forward, pushing the plastic alloy heat-treated workpiece lifted by the receiving plate 74 forward. When loading the plastic alloy heat-treated workpiece, the fixing device, together with the guide groove 71, the hanging plate 73 and the receiving plate 74, pushes the two sets of clamping plates 72 closer to each other, clamping the plastic alloy heat-treated workpiece above the receiving plate 74, thereby preventing the plastic alloy heat-treated workpiece from falling from the side during transportation, which would cause damage to the plastic alloy heat-treated workpiece. This solves the problem of the plastic alloy heat-treated workpiece being difficult to fix during transportation. When unloading the heat-treated plastic alloy parts after transportation, the pull rod 75, connecting plate 76 and push plate 77 are used to push the heat-treated plastic alloy parts forward, so that the workers can unload the heat-treated plastic alloy parts more quickly, improve the workers' work efficiency, and solve the problem that the heat-treated plastic alloy parts may be at a high temperature, and the workers need to take out the tools again when unloading manually, which is quite troublesome.
[0021] In this embodiment, when transporting heat-treated plastic alloy parts, first use tools to place the lower-temperature heat-treated plastic alloy parts on top of the base plate 1. After loading the lower-temperature heat-treated plastic alloy parts, push the handle 6 downwards. The handle 6 moves the placement box 4 downwards, retracting the telescopic rod 3. After the placement box 4 moves downwards, it limits the lower-temperature heat-treated plastic alloy parts on top of the base plate 1. Place the higher-temperature heat-treated plastic alloy parts in the fixing device above the placement box 4. Different heat-treated plastic alloy parts with different processing degrees are classified, stored, and transported. After placing the heat-treated plastic alloy parts to be transported, open the drawer 5 and place the tools inside the drawer 5 to prevent tools from being lost.
[0022] When loading heat-treated plastic alloy parts at high temperatures, the parts are placed onto the receiving plate 74 using a tool. Due to the weight of the parts, the receiving plate 74 moves downward relative to the placement box 4 after loading. As the receiving plate 74 moves downward, the hinge point between it and the hanging plate 73 moves downward as well. The end of the hanging plate 73 away from the receiving plate 74 is hinged to the side wall of the clamping plate 72, and the clamping plate 72 slides on the upper surface of the placement box 4. The clamping plate 72 is positioned at a height relative to the placement box 4. Since the angle remains constant, the hinge point between the hanging plate 73 and the clamping plate 72 will not shift vertically relative to the placement box 4. When the hinge point between the hanging plate 73 and the receiving plate 74 moves vertically, the hanging plate 73 itself also rotates. The rotation of the hanging plate 73 causes the clamping plate 72 to slide towards the receiving plate 74. Both sets of clamping plates 72 slide towards the receiving plate 74, thus bringing the two sets of clamping plates 72 closer together and clamping the plastic alloy heat-treated workpiece placed on the receiving plate 74. When the two sets of clamping plates 72 approach each other, the hinge point between the clamping plate 72 and the pull rod 75 also approaches each other, and the pull rod... The end of the pull rod 75 furthest from the clamping plate 72 is hinged to the connecting plate 76. Since the length of the connecting plate 76 remains constant, the hinge point between the pull rod 75 and the connecting plate 76 can only move back and forth. When the hinge points of the two sets of clamping plates 72 and the pull rod 75 approach each other, the pull rod 75 itself also rotates. The rotation of the pull rod 75 pushes the connecting plate 76 to move away from the receiving plate 74. When the connecting plate 76 moves away from the receiving plate 74, it also drives the push plate 77 to move together, so that the push plate 77 moves away from the heat-treated plastic alloy workpiece. When unloading is required, pull the handle 6 upwards. The handle 6 also drives the placement box 4 upwards. When the placement box 4 moves upward, the two sets of clamping plates 72 are pulled away from each other by the loading and unloading device and the auxiliary device. When the two sets of clamping plates 72 move away from each other, the hanging plate 73 is rotated. The rotation of the hanging plate 73 causes the receiving plate 74 to move upward. The upward movement of the receiving plate 74 lifts the plastic alloy heat-treated workpiece upward. When the two sets of clamping plates 72 move away from each other, the pull rod 75 is also rotated. The rotation of the pull rod 75 pulls the connecting plate 76 to move towards the receiving plate 74. The connecting plate 76 drives the push plate 77 to push forward, pushing the plastic alloy heat-treated workpiece lifted by the receiving plate 74 forward.
[0023] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a loading and unloading device is provided above the placement box 4 to facilitate loading and unloading of heat-treated plastic alloy parts. The loading and unloading device includes a guide plate 81, a fixing rod 82, a sliding block 83, and a limiting plate 84. The guide plate 81 is hinged to the end of the receiving plate 74 away from the handle 6. When loading and transporting the heat-treated plastic alloy parts, the receiving plate 74 moves downward, and the hinge point between the receiving plate 74 and the guide plate 81 moves downward. The fixing rod 82 is fixedly connected to... On the upper surface of the placement box 4, a sliding block 83 is hinged to the end of the fixed rod 82 away from the placement box 4. The end of the sliding block 83 away from the fixed rod 82 is slidably connected to the side wall of the guide plate 81. Therefore, the sliding block 83 can only rotate around the hinge point between the fixed rod 82 and the sliding block 83, causing the side wall of the guide plate 81 to slide around the upper end of the fixed rod 82. When the receiving plate 74 moves downward, it causes the guide plate 81 to rotate, making the guide plate 81 tilted with the end closer to the receiving plate 74 downward and the end away from the receiving plate 74 upward. The heat-treated plastic alloy workpiece above the receiving plate 74 is limited in front of the receiving plate 74. The receiving plate 74 moves upward, causing the guide plate 81 to rotate. With the help of the fixing rod 82 and the sliding block 83, the guide plate 81 is tilted so that the end closer to the receiving plate 74 is upward and the end farther away from the receiving plate 74 is downward. At this time, the push plate 77 pushes the heat-treated plastic alloy workpiece above the receiving plate 74 to the top of the guide plate 81. The heat-treated plastic alloy workpiece slides downward along the side wall of the guide plate 81 and slides out of the range of the receiving plate 74. The limiting plate 84 is fixedly connected to the upper surface of the placement box 4. The limiting plate 84 limits the two sets of clamping plates 72. When loading and transporting plastic alloy heat-treated parts, the loading and unloading device, together with the guide plate 81, the fixing rod 82 and the sliding block 83, limits the plastic alloy heat-treated parts, thereby preventing the plastic alloy heat-treated parts above the receiving plate 74 from squeezing each other and squeezing the plastic alloy heat-treated parts placed on the receiving plate 74 first. This solves the problem that plastic alloy heat-treated parts of different shapes may squeeze each other and fall off when loading them. When unloading heat-treated plastic alloy parts, the guide plate 81, fixing rod 82, and sliding block 83 work together to allow the heat-treated plastic alloy parts to slide slowly off the guide plate 81, thus preventing the parts from falling directly off the equipment and being damaged. At the same time, the limiting plate 84 restricts the sliding range of the clamping plate 72, preventing the clamping plate 72 from sliding too far apart, which would cause the receiving plate 74 to move upward too quickly, throwing the heat-treated plastic alloy parts up and out, thus damaging them. This solves the problem of the heat-treated plastic alloy parts being easily damaged when falling too quickly during unloading.
[0024] An auxiliary device for protecting the heat-treated plastic alloy parts is provided on the side of the placement box 4. The auxiliary device includes a hinge rod 91, a sliding plate 92, a strong spring 93, and a baffle 94. The hinge rod 91 is hinged to the side wall of the clamping plate 72 away from the hanging plate 73. The side wall of the limiting plate 84 has a groove, and the side wall of the hinge rod 91 fits against the inner wall of the groove. The sliding plate 92 is slidably connected to the side wall of the placement box 4. The end of the hinge rod 91 away from the clamping plate 72 is hinged to the upper surface of the sliding plate 92. When the placement box 4 is pushed downward to limit the bottom plastic alloy heat-treated parts, the downward movement of the placement box 4 causes the sliding plate 92 to move downward as well. One end of the strong spring 93 is slidably connected to the bottom surface of the sliding plate 92. The downward movement of the sliding plate 92 compresses the strong spring 93. When the placement box 4 moves to the lowest point, the sliding plate 92 is pushed upward by the restoring force of the strong spring 93. When the sliding plate 92 applies an upward pushing force, the hinge rod 91 needs to rotate, while the clamping plate 72 remains stationary. Therefore, the hinge rod 91 pushes the clamping plate 72, further clamping and fixing the heat-treated plastic alloy workpiece. The telescopic rod 3 passes through the baffle 94 and is fixedly connected at the point of penetration. The other end of the strong spring 93 is fixedly connected to the upper surface of the baffle 94. When transporting the heat-treated plastic alloy workpiece, this auxiliary device, in conjunction with the hinge rod 91, sliding plate 92, strong spring 93, and baffle 94, applies a pushing force to the clamping plate 72, making the clamping plate 72 more stable in clamping the heat-treated plastic alloy workpiece. This avoids the problem that the heat-treated plastic alloy workpiece is too heavy, and the inertia affects the sliding during transportation, causing the clamping plate 72 to be unable to clamp the heat-treated plastic alloy workpiece stably. This solves the problem that the clamping plate 72's fixing effect is reduced when the heat-treated plastic alloy workpiece is too heavy. When unloading heat-treated plastic alloy parts, the hinge rod 91, sliding plate 92, strong spring 93 and baffle 94 work together to apply tension to the clamping plate 72, pulling the clamping plates 72 away from each other, thereby preventing the heavy heat-treated plastic alloy parts above the receiving plate 74 from being difficult to lift, and solving the problem of difficulty in automatically unloading when the plastic alloy heat-treated parts are large.
[0025] In this embodiment, during loading and transportation of the heat-treated plastic alloy workpiece, the receiving plate 74 moves downwards. This causes the hinge point between the receiving plate 74 and the guide plate 81 to move downwards. The side wall of the guide plate 81 slides against the sliding block 83, which is hinged to the upper end of the fixed rod 82. Therefore, the sliding block 83 can only rotate around the hinge point between the fixed rod 82 and the sliding block 83, causing the side wall of the guide plate 81 to slide around the upper end of the fixed rod 82. As the receiving plate 74 moves downwards, it causes the guide plate 81 to rotate, resulting in an inclined position where the end closer to the receiving plate 74 points downwards and the end further away from the receiving plate 74 points upwards. The guide plate 81, positioned in front of the receiving plate 74, limits the movement of the heat-treated plastic alloy workpiece above the receiving plate 74, preventing it from obstructing the heat treatment process. When the workpiece is transported by the pushing equipment, it vibrates and falls due to the movement. When unloading the heat-treated plastic alloy workpiece, the receiving plate 74 moves upward, causing the guide plate 81 to rotate. With the help of the fixing rod 82 and the sliding block 83, the guide plate 81 is tilted so that the end closer to the receiving plate 74 is upward and the end farther away from the receiving plate 74 is downward. At this time, the push plate 77 pushes the heat-treated plastic alloy workpiece above the receiving plate 74 to the top of the guide plate 81. The heat-treated plastic alloy workpiece slides downward along the side wall of the guide plate 81 and slides out of the range of the receiving plate 74. The limiting plate 84 limits the two sets of clamping plates 72 to prevent the clamping plates 72 from sliding too far apart when they slide away from each other, which would cause the receiving plate 74 to move upward too fast and throw the heat-treated plastic alloy workpiece out, causing damage to the heat-treated plastic alloy workpiece.
[0026] When the placement box 4 is pushed downwards to limit the bottom plastic alloy heat-treated parts, the downward movement of the placement box 4 causes the sliding plate 92 to move downwards as well, compressing the strong spring 93. When the placement box 4 moves to the lowest point, the sliding plate 92 is subjected to the restoring force of the strong spring 93, applying an upward thrust. When the sliding plate 92 applies an upward thrust, the hinge point of the hinge rod 91 tends to move upwards. Since the end of the hinge rod 91 away from the sliding plate 92 is hinged to the side wall of the clamping plate 72, the hinge rod 91... The hinge point of the clamping plate 72 can only move horizontally relative to the placement box 4. Therefore, when the hinge point of the hinge rod 91 and the sliding plate 92 tends to move upward, the hinge rod 91 itself also tends to rotate. The rotation of the hinge rod 91 will push the clamping plate 72 to slide towards the baffle 94. Since a plastic alloy heat-treated workpiece is placed above the receiving plate 74, the clamping plate 72 cannot move closer to the workpiece after clamping it. Therefore, when the hinge rod 91 tends to rotate, it applies a push to the clamping plate 72. The force further provides clamping force for the heat-treated plastic alloy parts, preventing the clamping plates 72 from loosening due to inertia caused by the large mass of the parts during transportation, thus ensuring the clamping plates 72 can hold the parts securely. When the placement box 4 is pushed upwards, the two sets of clamping plates 72 pull the hinge rod 91 to rotate. The rotation of the hinge rod 91 pulls the sliding plate 92 upwards. When the sliding plate 92 slides upwards until the strong spring 93 returns to its original position, the baffle... Since 94 is fixed above the base plate 1, when the sliding plate 92 continues to slide upward, it stretches the strong spring 93. After being stretched, the strong spring 93 needs to restore its elasticity to exert a downward pulling force on the sliding plate 92, so that the sliding plate 92 is fixed relative to the base plate 1. When the sliding plate 92 is fixed relative to the base plate 1, the placement box 4 continues to move upward. The hinge rod 91 rotates under the pulling force of the sliding plate 92, pulling the clamping plates 72 away from each other, so as to avoid the plastic alloy heat-treated parts above the receiving plate 74 being too heavy to be lifted.
