Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rubber strip technology, specifically relating to a feeding device for the production of EPDM rubber strips. Background Technology
[0002] Rubber strips refer to a saturated polymer, mainly composed of ethylene and propylene through solution copolymerization, with a third monomer introduced to enhance its properties. This material has excellent aging resistance, weather resistance, electrical insulation, chemical corrosion resistance, and impact elasticity.
[0003] A review of announcement number CN217968299U reveals a feeding device for producing EPDM rubber strips. This technology discloses "an extruder and a material cart. The top surface of the extruder has a feed inlet. The material cart is parked beside the extruder. Multiple mounting blocks are fixedly connected to the inner wall of the material cart. A vertical rod is fixedly connected between every two vertically corresponding mounting blocks. A carrying plate is installed inside the material cart. This invention uses a guide plate to guide and limit the semi-finished rubber. A striking mechanism is used to strike the carrying plate, separating the tangled semi-finished rubber and preventing it from sticking together. A telescopic rod on the bottom of the guide plate can lift the guide plate. The guide plate carries the semi-finished rubber, reducing the contact area between the semi-finished rubber and the extruder, preventing friction between the extruder and the machine body, facilitating use, and eliminating the need for production personnel to manually straighten the semi-finished rubber."
[0004] Although this design can reduce the contact area between the semi-finished rubber and the extruder, avoid friction between the extruder and the machine body, and facilitate use by eliminating the need for production personnel to manually straighten the semi-finished rubber, the device is difficult to fully disperse various materials when mixing them. It requires a long stirring process to mix the materials, which reduces production efficiency.
[0005] To address the aforementioned issues, this application proposes a feeding device for the production of EPDM rubber strips. Utility Model Content
[0006] To address the problems mentioned in the background section, this invention provides a feeding device for the production of EPDM rubber strips. Through the action of a drive shaft and a distributing wheel, when different raw materials fall through the main feeding pipe to the position of the distributing wheel, the high-speed rotation of the distributing wheel drives the materials to fall into the mixing chamber, thereby achieving the dispersion and distribution of different materials, making subsequent mixing more efficient. Furthermore, the action of a pull rod and a closing ring allows for simultaneous material discharge and closure of the auxiliary feeding pipe, making the feeding process more controllable.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of EPDM rubber strips, including a mixing chamber and a main feeding pipe, and a drive shaft mounted on the inner surface of the main feeding pipe. A distribution wheel is also mounted on one end of the drive shaft, and the main feeding pipe is also connected to the surface of a closed ring. A pull rod is also mounted on one end of the closed ring, and the pull rod is mounted on the surface of the main feeding pipe.
[0008] As a preferred embodiment of the feeding equipment for producing EPDM rubber strips according to this utility model, the main feeding pipe is fixedly installed on the surface of the mixing chamber, and an auxiliary feeding pipe is also installed at an equal angle on the surface of the main feeding pipe, and the internal space of the auxiliary feeding pipe is connected to the internal space of the main feeding pipe and the mixing chamber.
[0009] As a preferred material feeding device for the production of EPDM rubber strips according to this utility model, a motor is fixedly installed on the top surface of the main feeding pipe, and one end of the motor is rotatably connected to one end of the transmission shaft.
[0010] As a preferred material feeding device for the production of EPDM rubber strips according to this utility model, the drive shaft passes through the main feeding pipe and extends into the interior of the mixing chamber and is fixedly connected to the surface of the distributing wheel.
[0011] As a preferred material feeding device for the production of EPDM rubber strips according to this utility model, the surface of the distributing wheel is equipped with arc-shaped plate-like geometric bodies at equal angles, and the top surface of the distributing wheel and the top surface of the inner surface of the mixing chamber are on the same horizontal plane.
[0012] As a preferred embodiment of the feeding device for producing EPDM rubber strips according to this utility model, the pull rod and the main feeding pipe are slidably connected, and the pull rod is fixedly installed on the surface of the closing ring. The closing ring is slidably connected to the end of the main feeding pipe and the auxiliary feeding pipe. The diameter of the closing ring matches the inner surface diameter of the main feeding pipe, and the height of the closing ring is greater than the inner diameter of the auxiliary feeding pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: under the action of the drive shaft and the distributing wheel, when different raw materials fall to the position of the distributing wheel through the main feeding pipe, the high-speed rotation of the distributing wheel can drive the material to fall into the interior of the mixing chamber, thereby realizing the dispersing and distributing of different materials, making the subsequent mixing more efficient. Under the action of the pull rod and the closing ring, the material inside the auxiliary feeding pipe can be discharged and closed at the same time, making the feeding operation more controllable.

[0023] Feeding equipment for the production of EPDM rubber strips, including mixing chamber 1.
[0024] In this implementation plan: The existing announcement number CN217968299U discloses a feeding device for the production of EPDM rubber strips. The technical means of this device will not be described in detail here. For improvements to this prior art, please refer to the following disclosure. In order to solve the technical problems existing in this prior art, such as the "When the device mixes various raw materials, it is difficult to fully disperse the various materials. It requires a long time of stirring to mix the materials, which will reduce the production efficiency" in combination, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a main feeding pipe 2 and an auxiliary feeding pipe 3 are added on the basis.
[0025] Furthermore:
[0026] like Figure 1 - Figure 4 As shown:
[0027] In conjunction with the above, it also includes a drive shaft 5 installed on the inner surface of the main feed pipe 2, a distribution wheel 6 installed at one end of the drive shaft 5, and the main feed pipe 2 is also connected to the surface of the sealing ring 8. A pull rod 7 is also installed at one end of the sealing ring 8, and the pull rod 7 is installed on the surface of the main feed pipe 2.
[0028] In this implementation scheme: the rotation of the distributing wheel 6 enables the raw materials to be mixed efficiently, making subsequent work more convenient and efficient; while the action of the pull rod 7 and the closing ring 8 allows for flexible control of the conveying and closing status of the auxiliary feeding pipe 3 to the raw materials.
[0029] Furthermore:
[0030] In an optional embodiment, the main feed pipe 2 is fixedly installed on the surface of the mixing chamber 1, and the surface of the main feed pipe 2 is also equipped with an auxiliary feed pipe 3 at equal angles, and the internal space of the auxiliary feed pipe 3 is connected to the internal space of the main feed pipe 2 and the mixing chamber 1.
[0031] In this embodiment, the auxiliary feeding pipe 3, which is installed at an equal angle on the surface of the main feeding pipe 2, can transport different raw materials into the interior of the main feeding pipe 2 through the auxiliary feeding pipe 3, and complete the mixing work by dispersing the materials through the dispersing wheel 6.
[0032] Furthermore:
[0033] In an optional embodiment, a motor 4 is fixedly mounted on the top surface of the main feed pipe 2, and one end of the motor 4 is rotatably connected to one end of the drive shaft 5.
[0034] In this embodiment, the motor 4 installed on the top surface of the main feeding pipe 2 can provide stable power to the transmission shaft 5 and the distributing wheel 6, thereby realizing the dispersing effect of raw materials and providing a certain degree of convenience for the mixing of raw materials.
[0035] Furthermore:
[0036] In an optional embodiment, the drive shaft 5 passes through the main feed pipe 2 and extends into the interior of the mixing chamber 1 and is fixedly connected to the surface of the distributing wheel 6.
[0037] In this embodiment, the drive shaft 5 extending into the mixing chamber 1 can be driven by the external motor 4 to rotate simultaneously with the dispersing wheel 6, thereby stably mixing and dispersing the raw materials.
[0038] Furthermore:
[0039] In an optional embodiment, the surface of the distributing wheel 6 is fitted with an arc-shaped plate geometry at equal angles, and the top surface of the distributing wheel 6 and the top surface of the inner surface of the mixing chamber 1 are on the same horizontal plane.
[0040] In this embodiment, the arc-shaped plate mounted on the surface of the distributing wheel 6 can disperse the raw materials when the transmission shaft 5 drives the distributing wheel 6 to rotate, thereby enabling the raw materials to be stably distributed in the mixing chamber 1 for uniform mixing.
[0041] Furthermore:
[0042] In an optional embodiment, the pull rod 7 is slidably connected to the main feed pipe 2, and the pull rod 7 is fixedly installed on the surface of the closing ring 8.

[0044] The working principle and usage process of this utility model are as follows: When different raw materials need to be mixed inside the mixing chamber 1, they can be fed through the auxiliary feeding pipe 3. At this time, the pull rod 7 and the closing ring 8 can be pulled to lift and the motor 4 can be started. The closing ring 8 will gradually rise and open the opening of the auxiliary feeding pipe 3, allowing the raw materials inside to enter the main feeding pipe 2. Then, under the action of the motor 4 and the transmission shaft 5, the distributing wheel 6 can be effectively driven to rotate. When the various raw materials in the main feeding pipe 2 reach the position of the distributing wheel 6, they will be thrown out under the rotation of the distributing wheel 6, thereby realizing the dispersion and distribution of different materials, making the subsequent mixing work more uniform and efficient.
[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
