Description

Technical Field

[0001] This utility model relates to the field of foam technology, and in particular to foam recycling and crushing equipment. Background Technology

[0002] Foam is a material made from foamed plastic particles and is widely used in various industrial products. During foam production, raw materials are mixed and stirred before being placed in a molding tank to allow the plastic particles to foam and form blocks of foam. Because the foam expands and grows in all directions during the foaming process, the outer contour of the finished foam will have irregular areas.

[0003] Therefore, after foaming, the outer contour of the foam needs to be cut to correct its shape. The excess foam pieces obtained from cutting the foam become scrap. Based on the requirements of saving and environmental protection, some manufacturers collect the scrap generated during foam production. Then, the collected scrap is crushed, mixed with adhesive, and molded into foam of the required shape, thereby achieving the purpose of recycling.

[0004] Existing foam crushing equipment is generally a device with an inverted cone-shaped feed hopper at the top, from which the crushed foam is discharged. When feeding, the operator needs to climb to a high platform to put the remaining material into the feed hopper, which is inefficient. Moreover, a lot of the foam residue is still quite large, which is inconvenient for the operator to handle. The operator is also prone to leaning forward when throwing the residue, which poses a safety hazard. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a lifting-type foam stirring device to solve the above problems.

[0006] The present invention adopts the following technical solution:

[0007] This utility model first provides a foam recycling and crushing equipment, which includes a feeding rack, a horizontal conveyor belt, a guide roller slope, a feeding hopper, a crushing knife holder and a discharge port.

[0008] The feeding rack includes a support rod and a sloping conveyor belt. The support rod stands vertically on the equipment placement surface. The top end of the sloping conveyor belt is rotatably connected to the support rod, forming an upwardly extending slope for conveying foam placed on it to its top. The top end of the horizontal conveyor belt is connected to the sloping conveyor belt and is suspended above the equipment placement surface. The guide roller slope includes multiple guide rollers arranged side by side. The guide roller slope extends downwards at an angle, and the top of the guide roller slope is connected to the side of the horizontal conveyor belt away from the feeding rack. The top of the feed hopper is connected to the bottom of the guide roller slope. The crushing blade holder is located below the feed hopper and is used to crush the foam into granules. The discharge port is connected to the feed hopper through the crushing blade holder and is used to discharge the granules.

[0009] Preferably, the angle between the slope of the guide roller and the equipment placement surface is 30 to 40 degrees.

[0010] Preferably, a foam steering roller surface is also mounted on the slope of the guide roller via a connecting rod. The foam steering roller surface is suspended above the slope of the guide roller, and the angle between the foam steering roller surface and the equipment placement surface is greater than the angle between the slope of the guide roller and the equipment placement surface.

[0011] Preferably, the top of the guide roller slope and the connection point of the horizontal conveyor belt are locked together on a support frame erected on the equipment placement surface.

[0012] Preferably, the inclined conveyor belt is provided with multiple baffles at intervals perpendicular to the belt surface for abutting the bottom end of the foam.

[0013] Preferably, the surface of the inclined conveyor belt is covered with an anti-slip polyurethane layer.

[0014] Preferably, the bottom of the baffle protrudes downward to form a flange, and the surface of the inclined conveyor belt is provided with a corresponding slot for the flange to be inserted, so that the baffle can be detachably inserted into the inclined conveyor belt.

[0015] The technical effects achieved by this utility model include:

[0016] This technical solution utilizes a feeding rack, a horizontal conveyor belt, and a sloped guide roller to achieve a gradual, controlled rise of the foam until it is tilted downwards at a suitable angle before being fed into the hopper. This design avoids direct connection between the feeding rack and the hopper, preventing the foam from becoming stuck or falling out of the hopper due to inertia as it remains tilted upwards after climbing to the top of the feeding rack. The horizontal conveyor belt allows the foam to smoothly transition from the top of the sloped conveyor belt to the sloped guide roller, preventing sudden changes in the foam's turning angle. The downward-sloping guide roller ensures the foam falls into the hopper at a suitable angle, and the tilted foam is easily interfered with by the crushing blades, reducing the likelihood of jamming. The use of multiple guide rollers arranged side-by-side changes the contact between the foam and the crushing blades from sliding friction to rolling friction, reducing resistance and improving the efficiency of the foam's descent. It solves the inconvenience and safety hazards of workers having to climb to high places to feed materials in existing technologies. Compared with existing technologies, this equipment can carry out foam recycling and crushing operations more efficiently and safely, improving work efficiency and reducing safety risks.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0023] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted. Figure 3 To clearly show the slots 120 and baffles 121 on the ramp conveyor belt 12, other ramp extensions of the ramp conveyor belt 12 are omitted and represented by wavy lines.

[0024] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a foam recycling and crushing equipment, which includes a feeding frame 1, a horizontal conveyor belt 2, a guide roller slope 3, a feeding hopper 4, a crushing knife holder 5, and a discharge port 6.

[0025] The feeding rack 1 includes a support rod 11 and a sloping conveyor belt 12. The support rod 11 stands vertically on the equipment placement surface, which is generally the ground. The top of the sloping conveyor belt 12 is rotatably connected to the support rod 11, forming an upwardly extending sloping surface for conveying the foam 100 placed on it to its top. The horizontal conveyor belt 2 is connected to the top of the sloping conveyor belt 12 and is suspended above the equipment placement surface. The guide roller slope 3 includes multiple guide rollers arranged side by side. The guide roller slope 3 extends downwardly, and the top of the guide roller slope 3 is connected to the side of the horizontal conveyor belt 2 away from the feeding rack 1. The top of the feed hopper 4 is connected to the bottom of the guide roller slope 3. The crushing knife seat 5 is located below the feed hopper 4 and is used to crush the foam 100 into granules. The discharge port 6 is connected to the feed hopper 4 via the crushing knife seat 5 and is used to discharge the granules.

[0026] The purpose of constructing the aforementioned horizontal conveyor belt 2 and guide roller slope 3 is that: the foam 100 that has just climbed to the top of the feeding rack 1 is still in an upward-sloping posture due to inertia. If the feeding rack 1 is directly connected to the feeding hopper 4, the foam 100 will fall into the feeding hopper 4 in an unstable manner. For some larger foam 100, it is easy to get stuck and cannot be crushed by the crushing knife block 5, and will gradually shrink. There will also be situations where the foam 100 falls outside the feeding hopper 4. The guide roller slope 3 is inclined downwards, which allows the foam 100 to fall smoothly into the feed hopper 4 at a suitable angle. The inclined falling foam 100 is easily interfered with by the crushing knife seat 5, reducing the occurrence of material jamming. The use of multiple guide rollers in parallel changes the contact mode between the foam 100 and the guide roller from sliding friction to rolling friction, reducing resistance and improving the sliding efficiency of the foam 100. The horizontal conveyor belt 2 allows the foam 100 to smoothly transition from the top of the inclined conveyor belt 12 of the loading rack 1 to the guide roller slope 3, avoiding excessive instantaneous changes in the turning angle of the foam 100. The inclined conveyor belt 12, the horizontal conveyor belt 2, and the guide roller slope 3 are all equipped with drive sources to drive their operation.

[0027] Therefore, foam 100 can be lifted to a high position by the feeding rack 1, and then its position is smoothly controlled by the horizontal conveyor belt 2. Subsequently, foam 100 is fed into the hopper at a suitable angle by the guide roller slope 3. This structural design not only solves the inconvenience and safety hazards of operators having to climb to a high position to feed the foam in existing technologies, but also avoids the problem of material jamming caused by improper feeding angle by allowing foam 100 to be fed into the hopper 4 at a downward angle through the guide roller slope 3. Compared with existing technologies, this equipment can perform foam recycling and crushing operations more efficiently and safely, improving work efficiency and reducing safety risks.

[0028] In this embodiment, the inclined conveyor belt 12 can be adjusted to accommodate the conveying needs of foam of different sizes by adjusting its inclination angle. The length and width of the horizontal conveyor belt 2 can be adjusted according to actual production needs to ensure that the foam 100 can smoothly transition from the inclined conveyor belt 12 to the guide roller slope 3. The inclination angle of the guide roller slope 3 can be further optimized to improve the sliding efficiency of the foam. The number and arrangement of the blades in the pulverizing blade holder 5 can be adjusted according to the hardness of the foam 100 to improve the pulverizing efficiency.

[0029] The angle between the guide roller slope 3 and the equipment placement surface is 30 to 40 degrees. This angle design ensures that the foam 100 can slide smoothly during the conveying process, while avoiding material accumulation or excessively rapid sliding due to an angle that is too large or too small. The inclination angle of the guide roller slope 3 can be adjusted by adjusting the height of the support frame or the installation position of the guide roller.

[0030] A foam steering roller surface 7 is also mounted on the guide roller slope 3 via a connecting rod 31. The foam steering roller surface 7 is suspended above the guide roller slope 3, and the angle between the foam steering roller surface 7 and the equipment placement surface is greater than the angle between the guide roller slope 3 and the equipment placement surface. When the foam 100 is about to be transferred from the horizontal conveyor belt 2 to the guide roller slope 3, its front end can first contact the foam steering roller surface 7. Guided by the foam steering roller surface 7, its overall posture is turned to tilt downwards, allowing the foam 100 to quickly adhere to the guide roller slope 3. By adding the foam steering roller surface 7, the problem of foam 100 jamming due to angle changes during conveying is solved. The angle difference between the foam steering roller surface 7 and the guide roller slope 3 allows the foam 100 to smoothly turn when transitioning from the guide roller slope 3 to the foam steering roller surface 7, avoiding jamming at the connection point due to sudden angle changes. Furthermore, the design of the foam guide roller surface 7 improves the foam conveying efficiency, reduces the need for manual intervention, and lowers operational risks. Compared with existing technologies, the technical solution of this application further enhances equipment safety and operational efficiency while ensuring smooth foam conveying.

[0031] Specifically, the top of the guide roller slope 3 and the connection point of the horizontal conveyor belt 2 are locked together on a support frame 21 erected on the equipment placement surface, which simplifies the structure of the equipment and reduces maintenance costs.

[0032] Multiple baffles 121 are spaced perpendicularly to the belt surface on the inclined conveyor belt 12 to abut the bottom of the foam 100. The baffles 121 are designed to prevent the foam 100 from sliding or falling during transport. The baffles 121, positioned perpendicularly to the belt surface and spaced apart, effectively abut the bottom of the foam 100, ensuring its stability during transport. The flange at the bottom of the baffle 121 engages with a slot 120 on the inclined conveyor belt 12, allowing for easy installation and removal, facilitating maintenance and replacement. The belt surface of the inclined conveyor belt 12 is covered with an anti-slip polyurethane layer, enhancing the friction between the belt and the foam 100 and further ensuring the stability of the foam 100 during transport.

[0033] The baffle 121 has a downward-protruding flange 122 at its bottom. The surface of the inclined conveyor belt 12 has corresponding slots 120 for inserting the flange 122, allowing the baffle 121 to be detachably inserted into the inclined conveyor belt 12. This allows the baffle 121 to be installed or removed according to actual needs, facilitating maintenance and replacement. The position and number of slots 120 can be adjusted according to the length of the conveyor belt and the requirements of the conveyed material. The shape and size of the flange 122 and slots 120 are not limited, as long as they can cooperate to fix the baffle 121 to the surface of the inclined conveyor belt 12.

[0035] The above description is only a specific embodiment of this application.
