Description

Technical Field

[0001] This utility model relates to the field of foam production technology, and in particular to an automatic feeding device for foam production. Background Technology

[0002] In the foam manufacturing industry, automatic feeding devices are one of the key production equipment, and their performance and efficiency directly affect the production quality of foam products and the smoothness of the overall production process. Foam materials have unique physical properties, such as softness and good elasticity, but the transmission process faces many challenges during production.

[0003] Traditional automatic foam feeding devices typically include a basic box structure, a conveying mechanism for foam transport, and a conveying component located on one side of the box. The conveying mechanism is usually inclined and installed on the inner wall of the box to transport foam from one place to another, while the conveying component is responsible for further transporting the foam to subsequent production processes.

[0004] However, during the transport process, due to its softness and certain adhesiveness, foam easily adheres to the surface of the transport mechanism. This adhesion can cause the foam to jam, stall, or even break during transport, severely affecting transport efficiency and product quality. Moreover, as production time increases, the adhesion problem between the foam and the transport mechanism becomes more severe, further reducing production stability and reliability. Existing technologies attempt to apply an anti-stick coating to the surface of the transport mechanism, but this method has significant limitations. The anti-stick coating gradually wears off and becomes ineffective after a period of use, requiring regular reapplication and maintenance. This not only increases production costs and downtime but also fails to fundamentally solve the adhesion problem between the foam and the transport mechanism, causing inconvenience in actual use.

[0005] Therefore, it is necessary to provide a new automatic feeding device for foam production to solve the above-mentioned technical problems. Utility Model Content

[0017] Compared with related technologies, the automatic feeding device for foam production provided by this utility model has the following advantages:

[0018] 1. This utility model provides a heating component on the inner wall of the housing. The inner sides of two arc-shaped heating plates are closely attached to the surface of the transmission mechanism to heat the surface of the transmission mechanism. The heating effect reduces the adhesion between the foam and the transmission mechanism, fundamentally reducing the occurrence of foam adhesion. This allows the foam to move more smoothly on the transmission mechanism, greatly improving the transmission efficiency of the foam. At the same time, it also ensures the integrity of the foam during the transmission process and improves the quality of the foam product.

[0019] 2. In this utility model, the internal heating wire is slidably installed inside the arc-shaped heating plate and is engaged with the top of the arc-shaped heating plate by a snap-fit ​​assembly. The position of the heating wire can be flexibly adjusted within the arc-shaped heating plate according to actual needs, i.e., the density of the heating wire can be adjusted. This allows for separate heating of different parts of the foam with varying viscosity. By adjusting the position of the heating wire within the arc-shaped heating plate, the surface temperature of the transmission mechanism can be adjusted, meaning that a temperature difference can be generated on the surface of the transmission components within the transmission mechanism. The foam near the raw material inlet has a relatively high viscosity due to the shorter mixing time; while the part near the outlet, after more thorough processing, may have reduced viscosity. At this point, the heating device in the feeding pipe generates a temperature difference, which can heat different viscosity parts of the foam. The temperature of the highly viscous areas is increased to reduce their viscosity, making the overall flow of the foam smoother and reducing transport blockages or stagnation caused by localized high viscosity.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please refer to the following: Figures 1 to 8 ,in, Figure 1 A schematic diagram of the overall structure of the automatic feeding device for foam production provided by this utility model; Figure 2 This is a schematic diagram of the internal structure of the box; Figure 3 This is a schematic diagram of the cross-sectional structure of the box; Figure 4 This is a schematic diagram of the heating assembly.

[0031] In some embodiments, such as Figures 1 to 8 As shown, the device includes a housing 1, a transmission mechanism for transferring foam, and a transmission assembly 51. The transmission mechanism is inclinedly arranged on the inner wall of the housing 1. The transmission assembly 51 is located on one side of the housing 1. The inner wall of the housing 1 is provided with a heating assembly for heating the surface of the transmission mechanism. The heating assembly includes a drive assembly, two arc-shaped heating plates 61, two heating wires 611, and two locking assemblies. The two heating wires 611 are slidably arranged inside the two arc-shaped heating plates 61. The two locking assemblies are fixed to the top of the two heating wires 611, and the other ends of the two locking assemblies are respectively engaged with the top of the two arc-shaped heating plates 61. The drive assembly is fixed to the inner wall of the housing 1. The two arc-shaped heating plates 61 reciprocate inside the housing 1 through the drive assembly, and the inner sides of the two arc-shaped plates 61 are in contact with the surface of the transmission mechanism.

[0032] The transmission mechanism and the transmission component 51 are mainly used to transmit the foam.

[0033] The drive assembly includes a fixed plate 3, a second motor 311, and a bidirectional lead screw 312. The fixed plate 3 is fixed to the inner wall of the housing 1. The surface of the fixed plate 3 has a groove 31 and a mounting groove 32. The mounting groove 32 is located on one side of the groove 31. The second motor 311 is fixed inside the groove 31. The two ends of the bidirectional lead screw 312 rotate on the inner wall of the mounting groove 32. The other end of the second motor 311 passes through the surface of the fixed plate 3 and is fixedly connected to one end of the bidirectional lead screw 312. The surface of the bidirectional lead screw 312 is threaded with two slide rods 6. The two slide rods 6 are located at the two ends of the bidirectional lead screw 312, that is, the two slide rods 6 are located at the opposite ends of the threads of the bidirectional lead screw 312. Both sides of the two slide rods 6 slide on the inner wall of the mounting groove 32. The tops of the two slide rods 6 are fixedly connected to the bottom of the arc-shaped heating plate 61.

[0034] The surfaces of the two arc-shaped heating plates 61 are provided with multiple equally spaced slots 612, and one end of each of the two engaging components is engaged with the surface of the slots 612.

[0035] Both fastening components include a connecting post 62, a connecting rod 63, a rotating shaft 631, a straight rod 632, and a locking block 633. The locking block 633 engages with the surface of the slot 612. The bottom of the connecting post 62 is fixedly connected to the top of the heating wire 611. One end of the connecting rod 63 is fixedly connected to the top of the connecting post 62. Both ends of the rotating shaft 631 rotate at the other end of the connecting rod 63. One end of the straight rod 632 is fixed to the surface of the rotating shaft 631. The locking block 633 is fixed to the other end of the straight rod 632. A heat insulation block 634 is also fixed to the other end of the straight rod 632. The heat insulation block 634 is located on the side of the straight rod 632 away from the locking block 633.

[0036] The heating wire 611 is connected to an external power supply device via a wire. The wire is long enough that it will not affect the heating when the arc-shaped heating plate 61 moves back and forth in a near or far motion.

[0037] When the heat insulation block 634 is slid laterally, the straight rod 532 can only rotate longitudinally to complete the engagement. At this time, the straight rod 532 remains stationary. The movement of the straight rod 532 will drive the connecting rod 63 and the connecting column 62 to move laterally, thereby driving the heating wire 631 to move and complete the adjustment of the density of the heating wire 631.

[0038] Specifically, when the heating component is in use, the second driving motor 311 is first activated. The rotation of the second driving motor 311 will drive the bidirectional lead screw 312 to rotate. Since the two sliding rods 6 are respectively threaded to both ends of the bidirectional lead screw 312, both sides of the sliding rods 6 slide on the inner wall of the mounting groove 32. This allows the rotation of the bidirectional lead screw 312 to drive the sliding rods 6 to move in a straight line along the surface of the bidirectional lead screw 312, either close to or far apart, without rotation. The two sliding rods 6 move closer or further apart, thereby driving the two arc-shaped heating plates 61 on top to move in a close or far apart motion, making it suitable for heating the outside of transmission mechanisms of different sizes. When foam is added into the transmission mechanism, the foam will have different properties such as viscosity and density in different parts due to uneven mixing of raw materials and fluctuations in production process. In this case, in order to prevent the foam from sticking to the tube wall inside the transmission mechanism, the heat insulation block 634 is held and the straight rod 5 is slid laterally. 32. The horizontal sliding of the straight rod 532 causes the heating wires 611 in the heating wire bundle to contract or expand within the arc-shaped heating plate 61, thereby changing the density of the heating wires 611 and creating a temperature difference at different locations on the surface of the arc-shaped heating plate 61. For example, pushing the straight rod 532 horizontally causes the heating wires 611 to gather above the arc-shaped heating plate 61, making the temperature above the arc-shaped heating plate 61 higher than the temperature below, thus heating the foam and regulating the temperature to a certain extent. After the density of the heating wires 611 is adjusted, the heat insulation block 634 is held and rotated, causing the straight rod 532 to rotate through the rotating shaft 631. The locking block 633 at the bottom of the straight rod 532 engages in the locking groove 612, limiting the position of the straight rod 532 and its connecting post 62, causing the heating wires 61 to gather and thus regulating the temperature difference.

[0039] Furthermore, by setting up a heat insulation block 634, the heat insulation block 634 will block the temperature emitted by the heating wire 611, preventing injury to the staff when sliding the straight rod 532, so that the staff has a point of force when sliding the straight rod 532, making it easier to adjust the temperature difference. Preferably, the heat insulation block 634 is an alumina ceramic heat insulation block.

[0040] Furthermore, by installing a heating component on the inner wall of the housing 1, and by having two arc-shaped heating plates 61 closely attached to the surface of the transmission mechanism, the surface of the transmission mechanism is heated. The heating effect reduces the adhesion between the foam and the transmission mechanism, fundamentally reducing the occurrence of foam adhesion, allowing the foam to move more smoothly on the transmission mechanism, greatly improving the transmission efficiency of the foam, while also ensuring the integrity of the foam during the transmission process and improving the quality of the foam product.

[0041] Furthermore, the heating wire 611 is slidably installed inside the arc-shaped heating plate 61 and is engaged with the top of the arc-shaped heating plate 61 by a snap-fit ​​assembly. The heating wire 611 can be flexibly adjusted in position within the arc-shaped heating plate 61 according to actual needs, that is, the density of the heating wire 611 can be adjusted to heat the different viscosity differences of different parts of the foam separately. By adjusting the position of the heating wire 611 within the arc-shaped heating plate 61, the surface temperature of the transmission mechanism can be adjusted, that is, the surface of the transmission components within the transmission mechanism can generate a temperature difference. The foam near the raw material inlet has a relatively high viscosity due to the short mixing time; while the part near the outlet, after more thorough processing, may have a lower viscosity. At this time, the arc-shaped heating plate 61 generates a temperature difference, which can heat the foam at different viscosity points, increase the temperature of the highly viscous areas, reduce their viscosity, make the overall flow of the foam smoother, and reduce the transportation blockage or stagnation caused by local high viscosity.

[0042] In some embodiments, reference is made to Figure 1 as well as Figure 2 As shown, a feed plate 11 is fixedly inclined on the inner wall of the box 1. The top of the feed plate 11 is provided with a feed inlet 111, and the bottom of the feed plate 11 is connected to the interior of the transmission mechanism.

[0043] Specifically, during use, the staff pours the foam into the feed port 111 at the top of the feed plate 11, allowing the foam to flow into the transmission mechanism.

[0044] In some embodiments, reference is made to Figures 1 to 3 As shown, the transmission mechanism includes an internally hollow inclined plate 2, a transmission component, a transmission cylinder 25, and a spiral tube 26. The transmission component rotates inside the inclined plate 2. The transmission cylinder 25 is fixed to the top of the inclined plate 2. The spiral tube 26 is rotatably disposed inside the transmission cylinder 25. The bottom of the spiral tube 26 is fixedly connected to one end of the transmission component. The top of the transmission cylinder 25 is provided with a discharge port 27, which is located at the top of the transmission component 51.

[0045] The heating component primarily heats the outer side of the transmission cylinder 25 during heating.

[0046] The bottom of the feed plate 11 is connected to the inside of the transmission cylinder 25 in the transmission mechanism.

[0047] The transmission assembly includes a motor 21, a pulley 22, a pulley 23, and a belt 24. One end of pulley 22 and pulley 23 rotates on the inner wall of the inclined plate 2. Pulley 22 and pulley 23 are connected by belt 24. The motor 21 is fixed to the top of the inclined plate 2. The rotor of the motor 21 passes through the surface of the inclined plate 2 and is fixedly connected to the other end of pulley 22. The other end of pulley 23 passes through the surface of the inclined plate 2 and is fixedly connected to the bottom of the spiral tube 26.

[0048] Specifically, during use, the motor 21 in the transmission assembly is started, which drives the pulley 22 to rotate. Since the pulley 22 and the pulley 23 are driven by the belt 24, the pulley 23 rotates inside the inclined plate 2, which in turn drives the spiral tube 26, which is fixedly connected to the other end of the pulley 23, to rotate. The spiral tube 26 rotates inside the transmission cylinder 25, completing the transportation of the foam and transporting the foam to the discharge port 27 for subsequent transmission.

[0049] In some embodiments, reference is made to Figure 1 As shown, an operating platform 5 is fixed on one side of the housing 1, a conveying assembly 51 is fixed on the top of the operating platform 5, a motor 3 52 is fixed on the top of the operating platform 5, the conveying assembly 51 is driven on the top of the operating platform 5 by the motor 3 52, and the surface of the conveying assembly 51 is also provided with a number of inserting components for inserting foam.

[0050] Among them, the conveying component 51 is a conveyor belt system, including a conveyor belt and two conveyor rollers. The conveyor belt is driven by the two conveyor rollers, and one of the conveyor rollers is fixedly connected to the rotor of the motor 52.

[0051] Multiple mounting components are fixed at equal intervals on the surface of the conveyor belt.

[0052] The top of the conveying assembly 51 is provided with a top plate 4, and a mechanical arm 41 is fixed at the bottom of the top plate 4. A box 54 for placing foam is also fixed on one side of the operating table 5, and the box 54 is located on one side of the conveying assembly 51.

[0053] Specifically, when the foam is transported to the discharge port 27 for subsequent transportation, the foam is transferred to the surface of the conveyor component 51, that is, the surface of the conveyor belt. The robotic arm 41 then attaches the foam to the surface of the mounting component. When the conveying speed of the conveyor is too fast, the robotic arm 41 will send some of the foam into the box 54 for collection. Preferably, there are multiple robotic arms 41.

[0054] In some embodiments, reference is made to Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, the multiple mounting components each include a mounting plate 1 511, a mounting plate 2 512, and a plug rod 1 53. The mounting plate 1 511 is fixed to the top of the conveying component 51, the mounting plate 2 512 is fixed to the top of the mounting plate 1 511, and the plug rod 1 53 is inserted into the interior of the mounting plate 2 512. The surface of the plug rod 1 53 is provided with a mounting hole 533, and the outer side of the mounting plate 2 512 is provided with a screw 513 for fixing the plug rod 1 53. One end of the screw 513 passes through one side of the mounting hole 533 and exits from the other side of the mounting hole 533, and a nut 514 is also threaded onto the surface of the screw 513.

[0055] The screw 513 is threadedly connected to the nut 514, which facilitates the disassembly and replacement of the insertion rod 53.

[0056] The top of the insert rod 53 is triangular in shape, with a sharp point. This sharp point provides good guidance during foam insertion. When the foam contacts the top of the insert rod 53, the sharp point of the triangle can easily cut into the edge of the foam, making it easier and smoother for the foam to slide down the insert rod 53 and be inserted into the appropriate position. This reduces the possibility of jamming or deviation during insertion and improves the efficiency and accuracy of feeding and insertion.

[0057] like Figure 6 as well as Figure 7 As shown, in the other two embodiments, insert rod 2 531 and insert rod 3 532 can also be selected. The bottom of insert rod 2 531 and insert rod 3 532 are provided with mounting holes 533, and installation is performed through the mounting holes 533.

[0058] Among them, the top of the second insertion rod 531 is semi-circular, and the top of the second insertion rod 632 is trapezoidal.

[0059] For insert rod 2 531: The semi-circular top is relatively smooth and rounded. During the foam insertion process, when it comes into contact with the foam, it will not generate a large cutting or scratching force on the foam surface like a sharp shape. This effectively reduces damage to the foam, ensures the integrity and quality of the foam, and avoids damage or tearing of the foam surface caused by the shape of the insert rod top being too sharp, which would affect the performance of the foam and the subsequent processing effect. The semi-circular shape makes the contact area between the foam and insert rod 2 531 gradually change during insertion, and the insertion process is relatively stable. The foam will not shake violently or deform due to sudden large resistance, which helps to maintain the stability of the foam during the insertion process, so that the foam can reach the designated position more smoothly. It is suitable for the installation of foam with high requirements for the integrity of the foam surface or softer materials.

[0060] For insert rod 2 632: The top of the trapezoid has a certain slope, similar to a triangle, which can guide the foam insertion to a certain extent, allowing the foam to slide smoothly along the sloping side of the trapezoid. At the same time, the upper part of the trapezoid is relatively wide, which can provide a certain support surface for the foam. After the foam is inserted, it keeps the foam in a relatively stable state on insert rod 3 532, preventing the foam from easily shaking or falling off in subsequent processes. This is beneficial for subsequent operations such as placing the shoe tongue or rolling edge on top of the foam and flipping the shoe tongue or rolling edge. It is suitable for foam installation that requires both insertion guidance and support stability.

[0061] Specifically, in use, when the robotic arm 41 inserts the foam onto the surface of the insertion component, the foam is inserted from the top of the insertion rod 53, the shoe tongue or roll of the foam is placed on top of the foam, the shoe tongue or roll is flipped over, and then the subsequent processes are carried out.

[0062] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0063] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
