Description

Technical Field

[0001] The utility model relates to the technical field of nylon processing equipment, in particular to a nylon raw material mixer with a strong magnetic iron-absorbing feeding device. Background Art

[0002] Polyamide, commonly known as nylon, is also known as Polyamide (PA for short) in English. It has a density of 1.15g / cm3 and is a general term for thermoplastic resins containing repeating amide groups — [NHCO] — on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer. The nylon pellet preparation process includes a nylon pellet processing production line, including a nylon mixing and molding machine, a water bath component, a dehydration component, a pelletizing mechanism and a uniform mixing and packaging mechanism. In the nylon pellet preparation process, the nylon raw material needs to be mixed evenly. In the vertical mixer of the existing technology, the material enters from the top, the material moves a short distance when mixing, the mixing effect needs to be improved, and the product quality is poor.

[0003] In view of this, the applicant applied for a patent CN202120243303.1 on January 28, 2021, which discloses a nylon raw material mixer, including a frame, a cylinder mounted on the frame, a feed trough at the bottom of the cylinder, a discharge pipe connected to the side wall of the cylinder, a power mechanism installed on the cylinder, and a lifting mechanism connected to the output end of the power mechanism and passing through the cylinder in the vertical direction for lifting the raw materials in the feed trough to the top of the cylinder; a plurality of supporting screens are also arranged in parallel inside the cylinder, the supporting screens are clamped on the inner surface of the cylinder and sleeved on the outer surface of the lifting mechanism, and a plurality of openings are opened on the supporting screens, and the openings of adjacent supporting screens are staggered; the lifting mechanism includes a rotating shaft connected to the output end of the power mechanism, a spiral blade screwed to the outer surface of the rotating shaft from bottom to top, and a sleeve covered on the outside of the spiral blade, the supporting screen is sleeved on the outer surface of the sleeve, and also includes a plurality of spoilers arranged on the outer surface of the sleeve. The patent allows raw materials to be added through a feed trough, and the raw materials in the feed trough slide down to the inside of a lifting mechanism located in the feed trough under the force of gravity. Under the action of a power mechanism, the lifting mechanism lifts the raw materials to the top of the cylinder to fully mix the raw materials, and then under the action of gravity, the raw materials fall to the bottom of the cylinder, and are fully mixed and discharged through a discharge pipe. The structure is simple and the mixing efficiency is high. However, the problem with this patent is that it does not have an iron filings impurity adsorption device. Since nylon raw materials often contain iron filings impurities, it is difficult to remove the iron filings impurities contained in the nylon raw materials after mixing. These iron filings impurities will have a greater adverse effect on the performance of the nylon product itself, and will also cause wear and damage to the nylon product molding machinery.

[0016] The structural principle and working principle of the utility model are further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 3 As shown, the utility model is a nylon raw material mixer with a strong magnetic iron suction feeding device, including a frame 1, a barrel 2 installed on the frame 1, a feeding device 3 located at the bottom of the barrel 2, a discharge pipe 4 connected to the side wall of the barrel 2, a power device 5 installed at the upper end of the barrel 2, and a lifting auger 6 connected to the power output end of the power device 5 and passing through the vertical direction of the barrel 2. The lifting auger 6 is used to lift the nylon raw material in the feeding device 3 to the top of the barrel 2. The outer cover of the lifting auger 6 is provided with a sleeve 61. The feeding device 3 includes a raw material feeding hopper 31 and a strong magnetic suction mechanism 32. The raw material feeding hopper 31 is provided with a feeding port 311 connected to the barrel 2, and the strong magnetic suction mechanism 32 is detachably installed on the outside of the feeding port 311 in the raw material feeding hopper 31. When the nylon raw material in the raw material feed hopper 31 enters the lower end position of the lifting auger 6 in the cylinder 2 through the feed port 311, the iron filings impurities mixed in the nylon raw material can be adsorbed and removed by the strong magnetic suction mechanism 32, and the iron filings adsorption effect is good and the iron filings are easy to remove.

[0018] like Figure 1-Figure 3As shown, the strong magnetic material suction mechanism 32 includes several vertical support plates 321 and several horizontal strong magnetic suction rods 322. The number of the support plates 321 and the strong magnetic suction rods 322 are four respectively. Several support plates 321 are arranged at intervals from left to right and are parallel to each other. Several strong magnetic suction rods 322 are arranged at intervals from top to bottom and are parallel to each other. Each support plate 321 is respectively provided with several suction rod fixing holes 3211. The strong magnetic suction rods 322 pass through the suction rod fixing holes 3211 of the support plates 321 and are fixedly connected to the support plates 321. There are gaps between the several supporting plates 321, and there are gaps between the several strong magnetic suction rods 322. The nylon raw material can enter the feed port 311 through the gaps, avoiding being blocked by the strong magnetic suction rods 322 to the greatest extent. In the process of the nylon raw material passing through the gaps and entering the feed port 311, the strong magnetic suction rods 322 absorb the iron filings impurities in the nylon raw material. After a period of time, the strong magnetic suction mechanism 32 is taken out from the raw material feed hopper 31 to clean the iron filings impurities adsorbed on the strong magnetic suction rods 322. After cleaning, the strong magnetic suction mechanism 32 is placed in the raw material feed hopper 31.

[0019] like Figure 3 As shown, as a preferred embodiment of the strong magnetic iron-absorbing rod 322, the strong magnetic iron-absorbing rod 322 includes a metal outer cylinder 3221 and a strong magnetic inner core 3222, and the strong magnetic inner core 3222 is detachably inserted into the metal outer cylinder 3221 from one end of the metal outer cylinder 3221. The advantage of this structure is that when cleaning the iron filings and impurities on the strong magnetic iron-absorbing rod 322, the strong magnetic inner core 3222 can be directly pulled out from the metal outer cylinder 3221, and the iron filings and impurities fall naturally, which is very convenient to clean. After cleaning, the strong magnetic inner core 3222 can be inserted into the metal outer cylinder 3221; and, if the strong magnetic inner core 3222 is damaged or the magnetic force is insufficient, the strong magnetic inner core 3222 can be easily replaced. The strong magnetic inner core 3222 is a permanent magnet inner core or an electromagnet inner core.

[0020] like Figure 1 As shown, there are two discharge pipes 4, which are symmetrically arranged on both sides of the outer wall of the cylinder 2. The two sides discharge materials at the same time to prevent excessive raw materials from accumulating inside the cylinder 2 and causing uneven mixing, further improving the mixing efficiency and the mixing effect.

[0021] like Figure 1 As shown, the cylinder 2 includes a cylindrical upper end 21 and a truncated cone-shaped lower end 22, the discharge pipe is installed at the truncated cone-shaped lower end 22, the cylinder 2 also includes a cylinder cover 23 located at the top of the cylindrical upper end 21, and the lifting auger 6 is provided with a rotating shaft 62, which passes through the cylinder cover 23 and is connected to the power mechanism 5. This structure can guide the material, so that the material falls along the lower end, further improves the mixing efficiency, and improves the mixing effect.

[0022] like Figure 1 As shown, the power device 5 includes a motor mounting seat 51, a motor 52 and a transmission belt 53. The motor mounting seat 51 is connected to one side of the upper end of the cylinder 2. The motor 52 is vertically mounted on the motor mounting seat 51. The rotating shaft of the motor 52 extends upward and is connected to a first pulley 521. The upper end of the rotating shaft 62 of the lifting auger 6 is connected to a second pulley 621. The transmission belt 53 is wound around the first pulley 521 and the second pulley 621. Through the driving action of the motor, the lifting auger 6 can be driven to rotate through the pulley transmission mechanism, so that the nylon raw material in the feeding device 3 can be continuously lifted to the upper end of the cylinder and fall into the cylinder.

[0023] The above is only a preferred embodiment of the present invention. Any slight modification, equivalent changes and modifications made to the above embodiments according to the technical solution of the present invention are within the scope of the technical solution of the present invention.
