Description

Technical Field

[0001] The utility model relates to the field of rubber, in particular to a rubber plastic preparation device. Background Art

[0002] Rubber is a material that is elastic, insulating, impermeable to water and air, and is made by extracting latex from plants such as rubber trees and rubber grass. Rubber is divided into natural rubber and synthetic rubber. Natural rubber mainly comes from the Hevea brasiliensis. When the skin of this rubber tree is cut, a milky white juice called latex will flow out. The latex is condensed, washed, molded, and dried to obtain natural rubber. Synthetic rubber is made by artificial synthesis. Different types of rubber can be synthesized using different raw materials (monomers).

[0003] When rubber is first collected, it contains impurities such as branches, small stones and bark, which need to be cleaned. Since rubber is sticky and insoluble in water, the existing method is to let the liquefied rubber flow through a filter to remove the impurities. It is necessary to stop frequently, take out the filter and replace it with a new one, which not only increases working time, but also delays production.

[0004] In view of the above problems, a rubber plastic preparation device is designed. Utility Model Content

[0005] In order to overcome the disadvantage that the liquefied rubber needs to be frequently stopped to take out the filter and replace it with a new one in order to remove the impurities in the filter when passing the liquefied rubber through the filter, the utility model provides a rubber plastic preparation device.

[0006] The technical scheme of the utility model is as follows: a rubber plastic preparation device, including a support frame, an extruder, a hot melter, a first filter plate, a second filter plate and a guide rod, the support frame is provided with an extruder, a hot melter is sleeved on the outside of the extruder, a notch is opened at the end of the extruder, a placement frame is symmetrically installed on both sides of the support frame, a first filter plate is movably arranged in the placement frame, a second filter plate is connected to the side of the first filter plate, the first filter plate and the second filter plate are movably inserted into the notch, and a guide rod is symmetrically installed in the placement frame.

[0007] In addition, it is particularly preferred that it also includes a threaded rod, a first scraper, a gear assembly and a motor. The threaded rod is symmetrically rotatable and penetrates through the frame, the motor is symmetrically installed in the support frame, the output shaft of the motor is connected to the gear assembly through a coupling, the gear assemblies are respectively connected to the threaded rod, the first scraper is threadedly connected to the threaded rod, and the first scraper is movably in contact with the first filter plate and the second filter plate.

[0008] In addition, it is particularly preferred that a second scraper and a cylinder are further included, the cylinder is installed on the top of the extruder, the second scraper is installed on the piston of the cylinder, and the second scraper is in contact with the outer surface of the extruder.

[0009] In addition, it is particularly preferred that a collecting frame is further included, and the collecting frame is symmetrically installed on the side of the placement frame.

[0010] In addition, it is particularly preferred that a rubber sleeve is further included, and the rubber sleeves are installed on both sides of the first filter plate and the second filter plate.

[0011] In addition, it is particularly preferred that a limiting plate is further included, and the outer sides of the placement frame are all clamped with the limiting plate.

[0012] The beneficial effect is: the hot melter works to heat the rubber in the extruder. After the rubber is liquefied, it flows through the first filter plate and flows out to the outlet. When the outflowing rubber becomes less and slower, the second filter plate is pushed into the extruder, and the first filter plate leaves the extruder and stays in the placement frame. A new filter can be replaced without stopping, thereby achieving the effect of continuous operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] Embodiment 1: A rubber plastic preparation device, such as Figure 1-Figure 4As shown, it includes a support frame 1, an extruder 101, a hot melter 2, a first filter plate 3, a second filter plate 31, a guide rod 4, a rubber sleeve 7 and a limit plate 8. The support frame 1 is provided with an extruder 101, and the hot melter 2 is sleeved on the outside of the extruder 101. A notch is opened at the right end of the extruder 101, and a placement frame is symmetrically installed on the front and back sides of the support frame 1. The first filter plate 3 is movably arranged in the placement frame, and the second filter plate 31 is connected to the side of the first filter plate 3. The first filter plate 3 and the second filter plate 31 are movably inserted into the notch, and the guide rod 4 is symmetrically installed in the placement frame. The first filter plate 3 is movably located in the two guide rods 4, and rubber sleeves 7 are installed on both sides of the first filter plate 3 and the second filter plate 31. The rubber sleeve 7 is convenient for pushing, and the placement frame is clamped with the limit plate 8 on the outside to prevent the first filter plate 3 from slipping out.

[0020] The rubber to be cleaned is poured into the extruder 101, and the hot melter 2 works to generate heat and transfer the heat to the extruder 101 to melt the rubber. The melted liquid rubber flows to the outlet end, and the first filter plate 3 on the front side of the outlet end intercepts the impurities in the liquid rubber, and the liquid rubber flows out through the outlet. When the rubber flowing out of the outlet becomes less and slower, hold the rubber sleeve 7, push the second filter plate 31, and push the second filter plate 31 into the gap of the extruder 101. The first filter plate 3 leaves the gap with the impurities, and the filtering work continues.

[0021] Embodiment 2: Based on embodiment 1, Figure 1 As shown, it also includes a threaded rod 5, a first scraper 6, a gear assembly 9, a motor 10 and a collecting frame 13. The threaded rod 5 is symmetrically rotatably penetrated in the placement frame, and the motor 10 is symmetrically installed in the support frame 1. Two threaded rods 5 are arranged on the same side of a placement frame. The output shaft of the motor 10 is connected to the gear assembly 9 through a coupling. The gear assembly 9 is respectively connected to the threaded rod 5. The first scraper 6 is threadedly connected to the threaded rod 5. The first scraper 6 is movably in contact with the first filter plate 3 and the second filter plate 31, so as to automatically remove impurities in the first filter plate 3. The collecting frame 13 is symmetrically installed on the side of the placement frame.

[0022] The first filter plate 3 with impurities stays in the placement frame, the motor 10 works, driving the gear assembly 9 to rotate, the gear assembly 9 drives the threaded rod 5 to rotate, the first scraper 6 moves along the guide rod 4, and the impurities sticking to the surface of the first filter plate 3 are removed. The cleaned impurities fall into the collection frame 13 below, which plays a cleaning role.

[0023] like Figure 4 As shown, it also includes a second scraper 11 and a cylinder 12. The cylinder 12 is installed on the top right side of the extruder 101, and the second scraper 11 is installed on the piston of the cylinder 12. The second scraper 11 contacts the outer surface of the extruder 101 to clean impurities on the outer surface of the extruder 101.

[0024] When the first filter plate 3 is penetrated, the gap may be stuck with impurities such as rubber. The cylinder 12 is started to push the second scraper 11 to move along the surface of the extruder 101 to clean the impurities stuck on the outer surface of the extruder 101, thereby cleaning the impurities.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
