Description

Technical Field

[0001] This utility model relates to the field of rubber heat treatment technology, specifically a processing heat treatment device for rubber manufacturing. Background Technology

[0002] Rubber granules need to be heated to a fluid state before they can be used, thus requiring a heating device for processing. However, existing devices have certain drawbacks. For example, CN216139243U discloses a raw material heating device for rubber pipe processing, which relates to the field of rubber pipes. This raw material heating device for rubber pipe processing includes a carrying tank. A fixed cover is threadedly connected to the outer surface of the top of the carrying tank. A rotating mechanism is fixedly and slidably connected above the fixed cover. A sliding mechanism is slidably connected above the fixed cover. A heating mechanism is rotatably connected to the bottom end of the sliding mechanism.

[0003] Although the above-mentioned device allows the heating structure to rise and rotate, thus changing the heating position, it is inconvenient to move the raw materials at the bottom of the heating furnace to the top, or to move the raw materials heated on the outside to the inside, causing heat exchange between the inside and outside of the raw materials. This results in uneven heat exchange throughout the interior, affecting the heating effect of the device. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment apparatus for rubber manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat treatment apparatus for rubber manufacturing includes a base, a heating furnace fixedly connected to the upper surface of the base, a cover detachably connected to the upper surface of the heating furnace, an electric heating tube nested on the outer surface of the heating furnace, a controller fixedly connected to the upper surface of the base, and a valve embedded in the lower surface of the heating furnace.

[0007] The lower surface of the cover is provided with a mixing mechanism, which includes a lifting pipe and an auger feeding shaft. The lifting pipe is fixedly connected to the lower surface of the cover, and the auger feeding shaft is rotatably connected to the inside of the lifting pipe.

[0008] The heating furnace is internally connected to a stirring mechanism, which includes a connecting frame, a scraper, and a guide plate. The connecting frame is rotatably connected to the bottom surface of the heating furnace, the scraper is fixedly connected to one end of the connecting frame, and the guide plate is fixedly connected to the upper end of the scraper.

[0009] Furthermore, a cover is nested on the outer surface of the heating furnace, and the electric heating tube and the controller are electrically connected.

[0010] Furthermore, a support leg is fixedly connected to the lower surface of the base.

[0011] Furthermore, the upper surface of the cover is fixedly connected to a feed pipe, the upper surface of the cover is fixedly connected to a first motor base, the upper surface of the first motor base is fixedly connected to a first stepper motor, and the auger feeding shaft and the output end of the first stepper motor are fixedly connected.

[0012] Furthermore, the outer surface of the lifting tube is provided with a feed inlet near the lower end and a discharge outlet near the upper end.

[0013] Furthermore, the stirring mechanism further includes a stirring blade and a second motor base. The stirring blade is fixedly connected to the outer surface of the scraper, and the second motor base is fixedly connected to the lower surface of the heating furnace. A second stepper motor is fixedly connected to the lower surface of the second motor base.

[0014] Furthermore, the output end of the second stepper motor is fixedly connected to the connecting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The output of the first stepper motor drives the auger feeding shaft to rotate, so that the raw material enters the lifting pipe from the feed port and is discharged from the discharge port. After being discharged, the raw material is fed down along the guide plate, so that the raw material located in the middle of the bottom rises, making it easier for the raw material on the outer edge of the bottom to be squeezed and move towards the center. After repeated cycles, the raw material is heated more evenly.

[0017] 2. The connecting frame drives the scraper to rotate, causing the scraper to scrape the inner wall of the heating furnace and scrape off some of the raw materials, reducing the time required for subsequent cleaning. At the same time, the scraping also drives the stirring blade to rotate, which stirs the raw materials and further assists in mixing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a heat treatment device for rubber manufacturing includes a base 2, a heating furnace 1 fixedly connected to the upper surface of the base 2, a cover 3 detachably connected to the upper surface of the heating furnace 1, an electric heating tube 101 nested on the outer surface of the heating furnace 1, a controller 103 fixedly connected to the upper surface of the base 2, and a valve 104 embedded in the lower surface of the heating furnace 1.

[0025] A mixing mechanism 4 is provided on the lower surface of the cover 3. The mixing mechanism 4 includes a lifting pipe 401 and an auger feeding shaft 402. The lifting pipe 401 is fixedly connected to the lower surface of the cover 3, and the auger feeding shaft 402 is rotatably connected to the inside of the lifting pipe 401.

[0026] The heating furnace 1 is rotatably connected to a stirring mechanism 5. The stirring mechanism 5 includes a connecting frame 503, a scraper 502, and a guide plate 501. The connecting frame 503 is rotatably connected to the bottom surface of the heating furnace 1, the scraper 502 is fixedly connected to one end of the connecting frame 503, and the guide plate 501 is fixedly connected to the upper end of the scraper 502.

[0027] Specifically, during use, the rubber raw material is placed inside the heating furnace 1. The controller 103 controls the electric heating tube 101 to heat the raw material to a molten state to complete the heat treatment operation. After the heat treatment operation, the raw material is discharged through the valve 104. During this process, the auger feeding shaft 402 rotates in conjunction with the lifting tube 401 to raise the raw material located in the middle of the bottom, which facilitates the raw material on the outer bottom to be squeezed and moved towards the center. After repeated cycles, the raw material is heated more evenly. During this process, the connecting frame 503 can drive the scraper 502 to rotate, so that the scraper 502 scrapes the inner wall of the heating furnace 1 and scrapes off some of the raw material, reducing the time required for subsequent cleaning.

[0028] Example 1

[0029] like Figure 1-4 As shown, a cover 102 is nested on the outer surface of the heating furnace 1, an electric heating tube 101 and a controller 103 are electrically connected, and a support leg 201 is fixedly connected to the lower surface of the base 2.

[0030] In this embodiment, the cover 102 reduces the heat leakage of the electric heating tube 101. The connection between the controller 103 and the electric heating tube 101 is prior art and will not be described in detail here. The support leg 201 supports the base 2, which facilitates the material receiving operation at the bottom of the heating furnace 1 later.

[0031] like Figure 1-4 As shown, a feed pipe 301 is fixedly connected to the upper surface of the cover 3, a first motor base 302 is fixedly connected to the upper surface of the cover 3, a first stepper motor 303 is fixedly connected to the upper surface of the first motor base 302, the auger feeding shaft 402 and the output end of the first stepper motor 303 are fixedly connected, a feed port 403 is opened on the outer surface of the lifting pipe 401 near the lower end, and a discharge port 404 is opened on the outer surface of the lifting pipe 401 near the upper end.

[0032] In this embodiment, raw materials can be fed into the feed pipe 301, and the first stepper motor 303 is started. The output end of the first stepper motor 303 drives the auger feeding shaft 402 to rotate, so that the raw materials enter the lifting pipe 401 from the feed port 403 and are discharged from the discharge port 404. The discharged raw materials are fed along the guide plate 501.

[0033] Example 2

[0034] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to scrape the material from the inner wall of the heating furnace 1 in Embodiment 1.

[0035] like Figure 1-4As shown, the stirring mechanism 5 also includes a stirring blade 504 and a second motor base 505. The stirring blade 504 is fixedly connected to the outer surface of the scraper plate 502. The second motor base 505 is fixedly connected to the lower surface of the heating furnace 1. A second stepper motor 506 is fixedly connected to the lower surface of the second motor base 505. The output end of the second stepper motor 506 is fixedly connected to the connecting frame 503.

[0036] In this embodiment, the second stepper motor 506 is started, and the output end of the second stepper motor 506 drives the connecting frame 503 to rotate. The connecting frame 503, together with the scraper 502, scrapes the heating furnace 1. At the same time, the scraping drives the stirring blade 504 to rotate. When the stirring blade 504 rotates, it stirs the raw materials and further assists in the mixing of the raw materials.
