Description

Technical Field

[0001] The utility model relates to the field of positioning tooling, in particular to a positioning tooling for processing a barrel of a twin-screw extruder. Background Art

[0002] The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding processing of extruded products. At present, the barrel of the twin-screw extruder is an important component of the twin-screw extruder, and the barrel of the twin-screw extruder is generally welded together through multiple short barrels, and the traditional barrel needs to use positioning tooling when welding the short barrels. At present, there is no tooling specifically used for the splicing and welding of the short barrels of the barrel. Generally, two support frames are used to support the two short barrels. The tooling personnel move the support to drive the short barrel to splice with another short barrel. Although this kind of tooling can also achieve the function of supporting and fixing the short barrel, it is easy to have a slight deviation between the central axes of the two short barrels, resulting in serious wear of the barrel after welding and the screw after installation. At the same time, the traditional bracket lacks the structure of purifying the air. When welding, it will produce welding fumes. There are irritating gases in these welding fumes, which can easily pollute the surrounding environment and affect the respiratory tract of the staff. Utility Model Content

[0003] The utility model aims to provide a positioning tool for processing a barrel of a twin-screw extruder, which has the advantages of good positioning effect and smoke purification.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a positioning tool for processing a twin-screw extruder barrel, comprising a mounting seat, a first bidirectional threaded rod is rotatably connected to the interior of the mounting seat through a bearing, a frame is symmetrically arranged on the top of the first bidirectional threaded rod, a second bidirectional threaded rod is rotatably connected to the interior of the frame through a bearing, a clamping plate is symmetrically arranged on the top of the second bidirectional threaded rod, the two opposite sides of the frames are rotatably connected to a rotating rod through a bearing, support plates are symmetrically bolted to the mounting seat, purification chambers are installed on the opposite sides of the two support plates, a limiting seat is symmetrically inserted into the top of the purification chamber, an activated carbon filter and a fiber filter are respectively installed on the two limiting seats, a sleeve connected to the interior of the purification chamber is installed on the purification chamber, and a negative pressure fan is installed inside the sleeve through a fixing member.

[0005] By adopting the above technical scheme, the utility model installs a second bidirectional threaded rod on the frame, and when the barrel assembly is placed on the frame, the rotating rod rotates and drives the second bidirectional threaded rod to rotate under the action of two bevel gears, so that the two clamping plates clamp the barrel assembly at the center of the frame, and the first bidirectional threaded rod is rotated to shorten the distance between the two frames, so that the two barrel assemblies placed on the two frames are close to each other and contact and position, thereby ensuring that the center points of the two barrel assemblies are consistent when welding, and ensuring the alignment of the barrel assemblies when welding. A support plate is installed on the mounting seat, and a purification chamber is installed on the support plate, which cooperates with the negative pressure fan installed inside the sleeve. When the negative pressure fan is started, negative pressure suction is generated at the cover body to absorb the welding fume, and the smoke particles are filtered through the fiber filter and the odor in the smoke is purified through the activated carbon filter, so that the smoke discharged from the sleeve will not carry particles and odor, thereby preventing it from polluting the environment.

[0006] The utility model is further configured as follows: a first connection block slidably connected to a mounting seat is symmetrically threadedly connected to the surface of the first bidirectional threaded rod, and the top of the first connection block is bolted to the bottom of the frame.

[0008] The utility model is further configured as follows: the surface of the second bidirectional threaded rod is symmetrically threadedly connected with a second connection block which is slidably connected to the frame, and the second connection block is bolted to the clamping plate.

[0010] The utility model is further configured as follows: a bevel gear is arranged inside the frame, the number of the bevel gears is two, the two bevel gears are meshed with each other, and the two bevel gears are respectively fixedly sleeved with the second bidirectional threaded rod and the rotating rod.

[0011] By adopting the above technical solution, when the rotating rod rotates, it is convenient to drive the second bidirectional threaded rod to rotate.

[0012] The utility model is further configured as follows: a slide block is symmetrically bolted to the bottom of the clamping plate, and a slide groove used in conjunction with the slide block is provided on the top of the frame.

[0013] The above technical solution is adopted to facilitate the sliding limit of the pallet.

[0014] The utility model is further configured as follows: wear-resistant pads are bonded to opposite sides of the two clamping plates, and a mounting block is bolted to the mounting seat.

[0015] The above technical solution is adopted to prevent the clamping plate from causing wear to the barrel assembly placed on the frame.

[0016] The utility model is further configured as follows: a cover body is installed on one side opposite to the two support plates, the cover body is communicated with the purification chamber, and a protective grille is installed inside the cover body.

[0017] The above technical solution is adopted to facilitate the absorption of welding fume.

[0018] The utility model is further configured as follows: a sealing gasket is fixedly sleeved on the surface of the limiting seat, and the sealing gasket is clamped with the plug-in slot on the top of the purification chamber.

[0019] By adopting the above technical solution, the sealing between the limit seat and the purification chamber is improved.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model installs a second bidirectional threaded rod on the frame. When the barrel assembly is placed on the frame, the rotating rod rotates to drive the second bidirectional threaded rod to rotate under the action of two bevel gears, so that the two clamping plates clamp the barrel assembly at the center of the frame.

[0022] 2. The utility model has a support plate installed on the mounting seat, a purification chamber installed on the support plate, and cooperates with a negative pressure fan installed inside the sleeve. When the negative pressure fan is started, negative pressure suction is generated at the cover body to absorb the welding fume, and the smoke particles are filtered through the fiber filter and the odor in the smoke is purified through the activated carbon filter, so that the smoke discharged from the sleeve will not carry particles and odor, thereby preventing it from polluting the environment.
