Description
Technical Field
[0001] The utility model relates to the field of packaging bag film processing, in particular to a material suction device for PE particles. Background Art
[0002] In the processing of packaging bag films, it is necessary to pump the PE particles stored in the hopper to a melting machine through a suction pipe for melting, and then blow the film through a film blowing machine. Then, when the suction pipe is in use, it is generally directly hung at the edge of the hopper opening, and the outer wall of the suction pipe directly contacts the edge of the hopper opening. After long-term use, the suction pipe is easily damaged by friction. At the same time, it is also necessary to arrange a special operator to specifically move the suction pipe towards the bottom of the hopper to ensure continuous material suction, which is not only time-consuming and laborious, but also has a relatively high production cost. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a material suction device for PE particles to solve the problems raised in the above background art.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a material suction device for PE particles, including a hopper for storing PE particles and a suction pipe for pumping out the PE particles in the hopper. A support and guiding mechanism for supporting the suction pipe and guiding it to move downward is arranged at the opening of the hopper. The support and guiding mechanism includes a vertically arranged cylindrical bracket, a suction pipe through-hole arranged on the cylindrical bracket, and multiple layers of roller groups are arranged at intervals from top to bottom on the cylindrical bracket. Each layer of roller group is horizontally provided with multiple rollers around the axis of the cylindrical bracket, and the outer walls of the rollers are all tangent to the outer wall of the suction pipe. A fixing mechanism for fixing on the hopper opening is also arranged on the cylindrical bracket;
[0005] To ensure the automatic downward sliding of the suction pipe, a counterweight for driving the suction pipe to move downward is arranged at the feeding port end of the suction pipe.
[0006] Further, the cylindrical bracket includes a group of roller fixing plates distributed in 360 degrees, and connecting bars are arranged between two adjacent roller fixing plates. The two ends of each roller are respectively rotatably fixed on the side walls of two adjacent roller fixing plates. A group of roller fixing holes are arranged on both side walls of the roller fixing plates, and the fixing mechanism is arranged on the roller fixing plates.
[0007] To facilitate fixing the cylindrical bracket on the hopper opening, the fixing mechanism includes a group of L-shaped support plates fixed on the roller fixing plates. One end of the L-shaped support plate is erected on the hopper opening, and a locking mechanism is also arranged on the L-shaped support plate.
[0008] Further, the locking mechanism includes a clamping seat, a clamping groove arranged on the clamping seat and adapted to the barrel wall, a locking screw hole arranged on the clamping seat, and a locking bolt acting on the barrel wall arranged in the locking screw hole.
[0009] Preferably, the barrel is of a conical structure, and the inner diameter of the barrel mouth is larger than the inner diameter of the barrel bottom.
[0010] To prevent the accumulation of granular materials, a vibrator is arranged on the barrel, a base is arranged at the bottom of the barrel, and a group of springs are arranged between the barrel and the base.
[0011] To ensure the stability of the barrel, a group of protective columns for preventing the barrel from tipping over are also arranged on the periphery of the barrel, and springs are also arranged between each protective column and the barrel.
[0012] To facilitate the assembly of the counterweight, a clamp is arranged on the suction pipe near the feed port end. The clamp includes a left clamp body and a right clamp body. Screw through holes are respectively arranged at both ends of the left clamp body and the right clamp body. Screws are sleeved in the screw through holes. Nuts are respectively arranged at both ends of the screws, and the two nuts act on the left clamp body and the right clamp body respectively. Placement frames for placing the counterweight are respectively arranged on the left clamp body and the right clamp body.
[0013] The beneficial effects of the present utility model: By arranging a support and guiding mechanism at the mouth of the barrel of the present utility model, the suction pipe passes through the suction pipe through hole of the cylindrical bracket. Under the action of each roller shaft, rolling friction is generated between the suction pipe and the cylindrical bracket, thereby effectively protecting the outer wall of the suction pipe and avoiding frictional damage. At the same time, under the action of the counterweight, the suction pipe can be straightened and driven to automatically slide down as the PE particles in the barrel decrease, eliminating the need for manual labor to specifically move the suction pipe to ensure continuous suction, saving labor costs for enterprises. In addition, the cylindrical bracket is arranged at the center of the barrel mouth, and the barrel is designed into a conical structure that is wider at the top and narrower at the bottom. As the suction pipe sucks materials, the remaining PE particles gather towards the center under the action of the vibrator and the springs, ensuring that the suction pipe can suck the PE particles in the barrel clean. The counterweight can be easily disassembled and assembled through the clamp, facilitating the assembly of the suction pipe in the suction pipe through hole.

[0026] Embodiment, as Figures 1 to 11 shown, a suction device for PE particles includes a material barrel 1 for storing PE particles and a suction pipe 2 for extracting the PE particles in the material barrel 1, and the suction pipe 2 is an elastic hose. A negative pressure pump is connected to the suction pipe 2, and the PE particles in the material barrel 1 are extracted from the suction pipe 2 by the action of the negative pressure pump. A support and guiding mechanism 3 for supporting the suction pipe 2 and guiding the suction pipe 2 to move downward is arranged at the mouth of the material barrel 1, and the suction pipe 2 is placed on the mouth of the material barrel 1 through the support and guiding mechanism 3.
[0027] Specifically, the support and guiding mechanism 3 includes a vertically arranged cylindrical bracket, a material suction pipe through-hole 31 provided on the cylindrical bracket. A plurality of layers of roller groups are arranged on the cylindrical bracket at intervals from top to bottom. Each layer of roller group is horizontally provided with a plurality of rollers 32 around the axis of the cylindrical bracket, and the outer walls of the rollers 32 are tangent to the outer wall of the material suction pipe 2. The outer wall of the material suction pipe 2 passes through the material suction pipe through-hole 31 while adhering to the rollers 32. A fixing mechanism 4 for fixing at the mouth of the material cylinder 1 is also provided on the cylindrical bracket. To fix the rollers 32, the cylindrical bracket includes a group of roller fixing plates 33 distributed 360 degrees around the center of the circle, and a connecting bar 34 is arranged between two adjacent roller fixing plates 33. The two ends of the connecting bar 34 are respectively fixed on the adjacent two roller fixing plates 33, and each roller fixing plate 33 is sequentially connected through the connecting bar 34. The two ends of each roller 32 are respectively rotatably fixed on the side walls of two adjacent roller fixing plates 33. A group of roller fixing holes 331 are provided on both side walls of the roller fixing plate 33, and the fixing mechanism 4 is arranged on the roller fixing plate 33.
[0028] For the convenience of fixing, the fixing mechanism 4 includes a group of L-shaped support plates 41 fixed on the roller fixing plate 33. One end of the L-shaped support plate 41 is placed on the mouth of the material cylinder 1, and the other end is fixed on the roller fixing plate 33. A locking mechanism 42 is also provided on the L-shaped support plate 41. The locking mechanism 42 includes a clamping seat 421, a clamping groove 4211 provided on the clamping seat 421 and adapted to the vertical cylindrical wall part 13 of the mouth of the material cylinder 1. A locking screw hole 422 is provided on the clamping seat 421, and a locking bolt 423 acting on the cylinder wall of the material cylinder 1 is arranged in the locking screw hole 422. By clamping the clamping groove 4211 on the cylinder wall of the material cylinder 1 and then tightening the locking bolt 423, the support and guiding mechanism 3 can be fixed at the center of the mouth of the material cylinder 1.
[0029] To prevent the accumulation of granular materials, the material cylinder 1 is of a conical structure, and the inner diameter of the mouth of the material cylinder 1 is larger than the inner diameter of the bottom of the material cylinder 1. A vibrator 5 is provided on the material cylinder 1, a base 11 is provided at the bottom of the material cylinder 1, and a group of springs 12 are arranged between the material cylinder 1 and the base 11. A group of protective columns 6 for preventing the material cylinder 1 from tipping over are also arranged around the material cylinder 1, and a group of springs 12 are also arranged between each protective column 6 and the material cylinder 1. Through the combined action of the vibrator 5 and the springs 12, the material cylinder 1 generates vibration, and the PE particles in the material cylinder 1 are leveled in the material cylinder 1 along with the vibration, and effectively prevent the PE particles from accumulating along the inner wall of the material cylinder 1 around the material cylinder 1.
[0030] To ensure that the material suction pipe 2 automatically descends as the amount of PE particles in the barrel 1 decreases, a counterweight 7 for driving the material suction pipe 2 to move downward is provided at the feeding port end of the material suction pipe 2.

Placement frames 22 for placing the counterweight 7 are respectively provided on the left clamp body 211 and the right clamp body 212. During assembly, first pass the material suction pipe 2 through the material suction pipe through hole 31 on the cylindrical support, then lock the clamp 21 on the material suction pipe 2 through the cooperation of the screw 213 and the nuts 214, and then place the counterweight 7 into the placement frame 22.
[0031] The working principle of the present utility model is as follows: The material suction pipe 2 passes through the material suction pipe through hole 31 close to each roller shaft 32. Under the action of the negative pressure pump, the PE particles in the barrel 1 are pumped away. Under the action of the vibrator 5, the PE particles accumulated around the inner wall of the barrel 1 slide down along with the vibration and are paved flat in the barrel 1. As the amount of PE particles in the barrel 1 decreases, under the action of the counterweight 7, the material suction pipe 2 automatically moves downward close to each roller shaft 32.
[0032] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, they are all within the protection scope of the present utility model.
