Description

Technical Field

[0001] The utility model relates to the technical field of material stirring, in particular to a PE packaging bag raw material processing device. Background Art

[0002] The main component of PE plastic bags is synthetic resin, which accounts for almost all of the plastics, and the content is very large. However, resin is not the same as plastic, it is a relatively primitive polymer, not plastic. When producing and processing PE packaging bags, the raw materials and additives and other auxiliary materials must first be mixed by mixing equipment, but the existing mixing equipment has low mixing efficiency for raw materials and high energy consumption.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN217373030U is that the first sieve plate and the second sieve plate are provided on the top of the processing box. The two sieve plates are continuously swung back and forth through the rotation of the rotating frame, so that the plastic particles can be screened and then enter the interior of the hot melt box for processing. This solves the problem that the existing raw material processing device is relatively simple and lacks a mechanism for pre-screening the plastic particles. After the traditional processing device is processed, the raw material output is not ideal due to the lack of mixing and stirring.

[0004] However, the device still has some shortcomings: during the stirring process, the bottom material and the upper material are prone to obvious hierarchical relationship, and it takes a lot of time to mix the upper and lower materials, thereby reducing the mixing efficiency of the raw materials and increasing the energy consumption of the equipment.

DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 3 As shown, a PE packaging bag raw material processing device proposed by the utility model includes a mixing barrel 1, a stirring assembly, a driving assembly, a side plate 12, a reciprocating screw 14 and a transmission mechanism. The mixing barrel 1 is connected to the feed hopper 2 and the discharge pipe 3. The mixing barrel 1 is a horizontal barrel, and a discharge hole is arranged on the mixing barrel 1. The discharge pipe 3 is covered on the outside of the discharge hole and is connected thereto, and a switch control assembly for controlling the internal on and off of the discharge pipe 3 is arranged inside the discharge pipe 3. The switch control assembly includes a sealing plate 4 and a hydraulic cylinder 5. The sealing plate 4 is located in the discharge pipe 3 and is slidably connected to the inner wall thereof, and the sealing plate 4 is inserted into the discharge hole and sealed therewith. The hydraulic cylinder 5 is arranged on the discharge pipe 3 and drives the sealing plate 4 to slide. The stirring assembly is located in the mixing barrel 1, and the stirring assembly includes a rotating shaft A6 and a scraper 7. The rotating shaft A6 is located in the mixing barrel 1 and is rotatably connected to the end cover of the mixing barrel 1. The rotating shaft A6 is parallel to the radial direction of the mixing barrel 1. The scraper 7 is connected to the rotating shaft A6 and slides on the arc-shaped inner wall of the mixing barrel 1. The driving assembly includes but is not limited to a motor 8. The motor 8 is connected to the mixing barrel 1, and the output end of the motor 8 is connected to the end of the rotating shaft A6. The driving assembly drives the stirring assembly to rotate. The side plate 12 is connected to the mixing barrel 1, the side plate 12 is rotatably connected to the bracket 13, and the side plate 12 is slidably connected to the slider 16. The slider 16 is rotatably connected to one end of the connecting rod 17, and the other end of the connecting rod 17 is rotatably connected to the bracket 13. The reciprocating screw rod 14 is rotatably connected to the side plate 12, and a screw nut matching it is sleeved on the reciprocating screw rod 14, and the screw nut is connected to the slider 16. The transmission mechanism includes but is not limited to a transmission assembly 15. The transmission assembly 15 is transmission-connected to the rotating shaft A9 and the reciprocating screw rod 14. The transmission assembly 15 includes a pulley and a toothed belt. The two pulleys are connected to the rotating shaft A6 and the reciprocating screw 14 respectively. The two pulleys are connected by a toothed belt transmission. The transmission mechanism is connected to the stirring assembly and the reciprocating screw 14. When the stirring assembly rotates, the reciprocating screw 14 is driven to rotate, so as to drive the slider 16 to slide back and forth.

[0026] In this embodiment, the raw materials to be stirred and mixed are added into the mixing barrel 1 along the feed hopper 2, and the motor 8 is started. The motor 8 drives the rotating shaft A6 to rotate. The rotation of the rotating shaft A6 drives the scraper 7 to rotate, and the raw materials in the mixing barrel 1 are stirred by the scraper 7. During the stirring process, the bottom material and the upper material are fully and quickly mixed, thereby improving the mixing efficiency of the raw materials. During the rotation of the rotating shaft A6, the reciprocating screw 14 rotates under the transmission action of the transmission assembly 15. During the rotation, the reciprocating screw 14 drives the slider 16 to slide back and forth. The reciprocating sliding slider 16 makes the connecting rod 17 swing with it, and the other end of the connecting rod 17 rotates around the fixed point on the bracket 13, so that the mixing barrel 1 swings under the support and pulling action of the connecting rod 17, so that the materials at the two ends of the mixing barrel 1 can be quickly mixed with the materials in the middle, further improving the processing efficiency. At the same time, since the structure only uses one motor 8 as the power mechanism, the purpose of energy saving is achieved. After the raw materials are mixed, the mixing barrel 1 is adjusted to tilt toward one side of the discharge pipe 3, and then the hydraulic cylinder 5 is started, which pulls the sealing plate 4 to slide, so that the channel in the discharge pipe 3 is opened, and the mixed materials are discharged along the discharge pipe 3.

[0029] In this embodiment, through the meshing structure of gear A9 and gear B11, the high speed of the rotating shaft A6 is transmitted through this structure to drive the reciprocating screw 14 to rotate at a lower speed, thereby making the reciprocating swing speed of the entire mixing barrel 1 slower, thereby improving its stability.
