Description

Technical Field

[0001] This utility model relates to the technical field of elastic material compression, specifically to an elastic material compression anti-rebound structure. Background Technology

[0002] When recycling elastic materials such as sponge and pearl cotton, a foam compressor is needed to compress the product volume. Existing foam compressors generally include a crushing chamber, a squeezing chamber, and a compression box. The crushing chamber is located above the squeezing chamber, and the squeezing chamber is connected to the compression box below. After the product is crushed in the crushing chamber, it enters the squeezing chamber for squeezing and is then conveyed to the compression box at the bottom. The pushing mechanism on one side of the compression box pushes the push plate inside the squeezing box to push the squeezed product out of the discharge port at the other end of the compression box.

[0003] For example, patent application number 201920642034.9 discloses a hydraulic foam compressor, which includes a motor, a crushing chamber, a crushing shaft, a filter screen, an extrusion chamber, a screw, a hydraulic pump, a pusher plate, a baffle, a photoelectric sensor, a compression box, and a pressure plate. The crushing chamber contains a crushing shaft, which is driven by a motor. The lower end of the crushing chamber is connected to the extrusion chamber, and a filter screen is installed between them. The extrusion chamber contains a screw, which is connected to a motor. The extrusion chamber is connected to the compression box, and a pusher plate is installed inside the compression box. The hydraulic pump is driven by the pusher plate. During operation, the lower end of the crushing chamber serves as the discharge port and connects to the extrusion chamber. The hydraulic pump drives the pusher plate to transport the compressed elastic material into the compression box (also called an extrusion shaping groove), and finally, it is discharged from the outlet at the other end of the compression box. However, in this type of foam compressor, during the compression process, the pusher plate can only push a fixed amount of material at a time. The material is fed into the compression chamber, where it is then pushed back to its original position by the pusher plate. The extruded material continues to be squeezed through the compression chamber, and then the pusher plate again delivers the squeezed material to the compression chamber. This reciprocating motion pushes the extruded material from the front of the compression chamber out of the discharge port. However, the elastic material has a certain degree of elasticity. During the pusher plate's reset process, the squeezed material in the compression chamber easily deforms and rebounds after the external force disappears, blocking the discharge port connecting the compression chamber and the extrusion chamber. This reduces the discharge volume from the compression chamber and affects the discharge efficiency. The current method involves lengthening the overall length of the compression chamber and the pusher plate's pushing path. This ensures that even if the elastic material rebounds after the pusher plate resets, it won't block the discharge port. However, this structural design undoubtedly increases the overall size of the final equipment and the pushing time, ultimately lengthening the discharge time of the elastic material and reducing work efficiency. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an elastic material compression anti-rebound structure to solve the problem mentioned in the background art that the elastic material squeezed into the extrusion shaping groove of the existing compressor is prone to rebound, which affects the discharge efficiency of the extrusion equipment, while increasing the size of the equipment and reducing the working efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic material compression anti-rebound structure, including an extrusion shaping groove, one end of which serves as a discharge port. A mounting through hole communicating with the interior of the extrusion shaping groove is provided on the top surface of the extrusion shaping groove. An anti-rebound mechanism is provided in the mounting through hole to limit the compressed product in the extrusion shaping groove and prevent the compressed product from rebounding when pressed down. The anti-rebound mechanism includes a hydraulic cylinder and a lower pressure plate. One end of the lower pressure plate is hinged to one side of the mounting through hole. The hydraulic cylinder is located at the upper end of the extrusion shaping groove. The piston rod of the hydraulic cylinder is connected to the top surface of the lower pressure plate, and the connection point between the piston rod of the hydraulic cylinder and the lower pressure plate is far away from the hinge point between the lower pressure plate and the mounting through hole.

[0006] Preferably, a discharge port connecting the extrusion chamber and the extrusion shaping groove is provided above the extrusion shaping groove, and a baffle that can block the discharge port is slidably connected above the extrusion shaping groove.

[0007] Preferably, for ease of installation, a gantry frame is provided above the extrusion and shaping groove, and the base of the hydraulic cylinder is hinged to the bottom of the gantry frame via a hinge shaft.

[0008] Preferably, to further facilitate installation, a hinge seat is provided on both sides of the mounting through hole, and a concave positioning seat is provided on both sides of the lower pressure plate. Each concave positioning seat is hinged to the hinge seat through a hinge shaft.

[0009] Preferably, the lower pressure plate has a fan-shaped structure, and the bottom and top surfaces of the lower pressure plate are flat, with the arc surface of the lower pressure plate facing the feed port.

[0010] Preferably, the extrusion shaping groove is provided with a pusher plate that can move along the length of the extrusion shaping groove, and the pusher plate is located on one side of the discharge port.

[0012] Preferably, the mounting through hole is located near the discharge port and on the other side of the discharge port.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the anti-rebound mechanism added to this structure can prevent the compressed product from rebounding and returning to the bottom of the discharge port after the external force of the push plate reset disappears, thus blocking the discharge port and slowing down the discharge speed. Therefore, this structure can prevent the compressed product from rebounding and affecting efficiency. At the same time, it is not necessary to lengthen the entire extrusion shaping groove and lengthen the pushing path of the push plate, which ultimately reduces the overall volume of the compressor and further improves the working efficiency of the final equipment.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Example 1

[0023] Please see Figures 1-5 As shown, this embodiment discloses an elastic material compression anti-rebound structure, including an extrusion shaping groove 1. One end of the extrusion shaping groove 1 serves as a discharge port 2. A mounting through hole 3 communicating with the interior of the extrusion shaping groove 1 is provided on the top surface of the extrusion shaping groove 1. An anti-rebound mechanism is provided in the mounting through hole 3 to limit the compressed product in the extrusion shaping groove 1 and prevent the compressed product from rebounding when pressed down. The anti-rebound mechanism includes a hydraulic cylinder 4 and a lower pressure plate 5. One end of the lower pressure plate 5 is hinged to one side of the mounting through hole 3. The hydraulic cylinder 4 is located at the upper end of the extrusion shaping groove 1. The piston rod of the hydraulic cylinder 4 is connected to the top surface of the lower pressure plate 5, and the connection point between the piston rod of the hydraulic cylinder 4 and the lower pressure plate 5 is far away from the hinge point between the lower pressure plate 5 and the mounting through hole 3. Furthermore, for easier installation... A hinge seat 10 is provided on both sides of one side of the mounting through hole 3, and a concave positioning seat 11 is provided on both sides of one side of the lower pressure plate 5. Each concave positioning seat 11 is hinged to the hinge seat 10 through a hinge shaft 14. In this embodiment, the lower pressure plate 5 has a fan-shaped structure, and the bottom and top surfaces of the lower pressure plate 5 are flat. The arc surface of the lower pressure plate 5 faces the feeding port 6. This allows the lower pressure plate 5 to work with the oil cylinder 4, with one end hinged in the mounting through hole 3 and the other end pressing downward, i.e., the arc surface pressing downward. The lower surface of the lower pressure plate 5 is used to press and limit the compressed product below, preventing it from rebounding below the feeding port 6. At the same time, the arc surface of the lower pressure plate 5 is designed to ensure a certain degree of smoothness, so that if there is a product in front, it will not be damaged.

[0024] Preferably, a discharge port 6 connecting the extrusion chamber and the extrusion shaping groove 1 is provided above the extrusion shaping groove 1. A baffle 7 that can block the discharge port 6 is also slidably connected above the extrusion shaping groove 1. The baffle 7 can be connected to a pushing mechanism such as a cylinder to push the baffle 7 to move and close or open the discharge port 6. As for how the baffle 7 is connected to the pushing mechanism, and the structural setting of the pushing mechanism is conventional technology in the field, it will not be described in detail below.

[0025] The mounting through hole 3 is located near the discharge port 6 and on the other side of the discharge port 6, so as to directly limit and squeeze the compressed product that is conveyed.

[0026] Preferably, for ease of installation, a gantry frame 8 is provided above the extrusion shaping groove 1, and the base of the hydraulic cylinder 4 is hinged to the bottom of the gantry frame 8 via a hinge shaft 9. The installation of the hydraulic cylinder 4 is facilitated by setting up the gantry frame 8.

[0027] Preferably, the extrusion shaping groove 1 is provided with a push plate 12 that can move along the length of the extrusion shaping groove 1, and the push plate 12 is located on one side of the discharge port 6. The push plate 12 is provided inside the extrusion shaping groove 1. The push plate 12 can be connected to a pushing mechanism such as a cylinder in the future, so that when the push plate 12 is working, the compressed product formed below the discharge port 6 is conveyed to the discharge port 2. As for how the push plate 12 is connected to the pushing mechanism, and the structural setting of the pushing mechanism is conventional technology in the field, it will not be described in detail below.

[0028] Preferably, in order to improve the heat dissipation effect, the extrusion shaping groove 1 is a rectangular structure, and heat dissipation holes 13 are provided on both the front and rear sides of the extrusion shaping groove 1 near the discharge port 2. By providing heat dissipation holes 13 on the front and rear sides of the extrusion shaping groove 1, the internal compressed product can be vented and cooled.

[0029] The working principle of this structure is as follows: This structure adds an anti-rebound mechanism to the extrusion and shaping groove 1 to limit the compressed product in the extrusion and shaping groove 1 during pressing and to prevent the compressed product from rebounding. The anti-rebound mechanism consists of a hydraulic cylinder 4 and a lower pressure plate 5. One end of the lower pressure plate 5 is hinged to the extrusion and shaping groove 1. During operation, the hydraulic cylinder 4 drives the lower pressure plate 5 to rotate downwards around the hinge shaft 14. The end away from the hinge shaft 14 presses down and limits the compressed end in the extrusion and shaping groove 1. This prevents the compressed product from rebounding after the external force of the push plate 12 disappears and returning to the bottom of the discharge port 6, thus blocking the discharge port 6 and slowing down the discharge speed. Therefore, this structure can avoid the compressed product rebounding and affecting efficiency. At the same time, it does not require lengthening the entire length of the extrusion and shaping groove 1 and lengthening the pushing path of the push plate 12, ultimately reducing the overall volume of the compressor and further improving the working efficiency of the final equipment.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
