Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber floor mat production technology, and in particular to a rubber preheating device for EPDM rubber floor mat production. Background Technology
[0002] EPDM rubber, or ethylene propylene diene monomer rubber, is a terpolymer of ethylene, propylene, and a non-conjugated diene. It features low density and high filler content, reducing product costs; excellent aging resistance, allowing for long-term use at 120°C; strong corrosion resistance; and good resistance to various polar chemicals. It also possesses excellent resistance to water vapor, superheated water, and electrical insulation properties. Its elasticity is second only to natural rubber and butadiene rubber, but its self-adhesion and mutual adhesion are poor. EPDM rubber is widely used in automobiles, construction, electrical systems, pipelines, and cables, and is an indispensable material in modern industry.
[0003] When producing EPDM rubber floor mats, a hot air circulating oven is needed to preheat the EPDM rubber raw material. The preheated rubber material is placed on a tray, and then a support with the tray is placed inside the hot air circulating oven for preheating. However, the existing hot air circulating ovens lack a structure to control the rotation of the support, which causes the hot air to not contact the surface of the rubber material evenly, reducing the preheating efficiency of the rubber material.
[0004] Therefore, in response to the above problems, a new preheating device for EPDM rubber mat production is proposed. Utility Model Content
[0005] To overcome the problems existing in related technologies, this utility model provides a rubber preheating device for EPDM rubber floor mat production. It can utilize a rotating structure to rotate the internal support of the hot air circulating oven to ensure uniform preheating of the rubber material. At the same time, it can clamp supports of different sizes that can rotate inside the hot air circulating oven, improving the convenience of the hot air circulating oven.
[0006] To achieve the above objectives, the first aspect of this utility model provides a rubber preheating device for the production of EPDM rubber floor mats, comprising:
[0007] The oven body, the support body, the first truncated cone, the second truncated cone, the drive motor, and the extrusion mechanism;
[0008] The oven body has a support body symmetrically arranged inside. A first truncated cone located below the support body is symmetrically installed inside the oven body. A second truncated cone located inside the oven body is located above the support body. A drive motor located inside the oven body is located above the second truncated cone. The output end of the drive motor is fixedly connected to the upper surface of the second truncated cone. A pressing mechanism for clamping the support body from the left and right sides is installed inside the first truncated cone.
[0009] Furthermore, the extrusion mechanism includes a bidirectional lead screw, a first movable block, and a first extrusion plate;
[0010] The first truncated cone is rotatably connected to a bidirectional lead screw. A first movable block that meshes with the bidirectional lead screw is symmetrically slidably installed inside the first truncated cone. A first pressing plate is fixedly connected to the upper surface of the first movable block. The first pressing plate is in contact with the left and right sides of the bracket body.
[0011] Furthermore, a drive rod is symmetrically rotatably connected to the upper surface of the first cylindrical platform, and the bottom end of the drive rod is connected to both ends of the bidirectional lead screw through bevel gear meshing.
[0012] Furthermore, the two sides of the bidirectional lead screw are provided with first threaded rods that are rotatably connected to the inside of the first truncated cone. One end of the first threaded rod is connected to the surface of the bidirectional lead screw through a bevel gear. A second movable block is engaged with the first threaded rod and slidably connected to the inside of the first truncated cone. A guide shell is fixedly connected to the upper surface of the second movable block. A second extrusion plate is slidably installed inside the guide shell. The second extrusion plate is in contact with the front and rear sides of the bracket body.
[0013] Furthermore, the guide shell is always located below the bottom of the main body of the support.
[0014] Furthermore, a second threaded rod that meshes with the second extrusion plate is rotatably connected inside the guide housing.
[0015] Furthermore, electric push rods are symmetrically mounted on the lower surface of the second truncated cone, and the moving end of the electric push rod is fixedly connected to the upper surface of the first truncated cone.
[0016] The technical solution provided by this utility model can include the following beneficial effects:
[0017] In this example, by installing a first truncated cone, a second truncated cone, a drive motor, and an extrusion mechanism, a tray containing adhesive is placed on the support body. The first truncated cone clamps the support body firmly through the extrusion mechanism. The first truncated cone moves upward, and the lower surface of the second truncated cone contacts the upper surface of the support body. The drive motor drives the second truncated cone to rotate, which in turn drives the support body to rotate, so that the hot air generated by the oven body can evenly contact the adhesive.

[0038] Specifically, the extrusion mechanism includes a bidirectional lead screw 6, a first movable block 7, and a first extrusion plate 8;
[0039] The first truncated cone 3 is rotatably connected to a bidirectional lead screw 6. The first movable block 7, which is symmetrically slidably installed inside the first truncated cone 3 and meshes with the bidirectional lead screw 6, is fixedly connected to the upper surface of the first movable block 7.

[0041] Specifically, the bidirectional lead screw 6 has a first threaded rod 10 on both sides that is rotatably connected to the inside of the first truncated cone 3.

[0045] In this embodiment, how to ensure uniform preheating of the adhesive compound, combined with Figure 1 and Figure 2 The specific implementation method is as follows: the tray containing the adhesive is placed on the support body 2, the first truncated cone 3 is clamped firmly on the support body 2 by the extrusion mechanism, the first truncated cone 3 moves upward, the lower surface of the second truncated cone 4 contacts the upper surface of the support body 2, the drive motor 5 drives the second truncated cone 4 to rotate, and drives the support body 2 to rotate, so that the hot air generated by the oven body 1 can evenly contact the adhesive.
