Description

Technical Field

[0001] This utility model relates to the field of PE film processing technology, specifically a stretching mechanism for PE film processing. Background Technology

[0002] A search revealed that the authorized patent CN220700377U discloses a stretching mechanism for PE film processing. It includes a housing, a front panel, a PE film body, and auxiliary devices. The auxiliary devices include an adjusting seat, a slider, a fixing block, a fastening nut, a fixing roller, a stretching roller, a sealing plate, and an air supply assembly. During PE film stretching, the air supply assembly delivers warm air for heating, and then the film is stretched in conjunction with the fixing roller and the stretching roller. The sealing plate is used to adjust the size of the inlet and outlet, facilitating the passage of PE film bodies of different thicknesses. Simultaneously, loosening the fastening nut allows the slider to slide up and down, thereby adjusting the clearance between the fixing roller and the stretching roller, facilitating the passage of PE film bodies of different thicknesses. This allows for adjustment during PE film stretching, enabling the heating and stretching of films of different thicknesses, improving the mechanism's practicality and ease of use.

[0003] However, the above technical solution still has the following shortcomings in use: The device requires sequential adjustment of the two stretching rollers, which is cumbersome, and cannot be adjusted externally; the door must be opened for adjustment, further increasing the complexity. To address these issues, we propose a stretching mechanism for PE film processing. Utility Model Content

[0004] The purpose of this invention is to provide a stretching mechanism for PE film processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stretching mechanism for PE film processing, comprising: The box body is equipped with an adjustment mechanism. Two fixed rollers are rotatably installed in the inner cavity of the box body, and a tension roller is provided above each of the two fixed rollers. The adjustment mechanism includes a fixed base, which is fixedly installed on the top wall of the box body. A sliding groove is opened on the fixed base, and a sliding column is slidably connected in the sliding groove. Sliding rods are fixedly welded to the bottom walls of both ends of the sliding column. The two sliding rods are slidably connected in two through holes in the top wall of the box body. Mounting blocks are fixedly welded to the bottom ends of the two sliding rods. The two tension rollers are rotatably installed on the two mounting blocks respectively. A precision screw is rotatably installed in the middle of the top wall of the sliding column, and the precision screw is threadedly connected to the fixed base.

[0006] Preferably, two aligned through slots are provided on the front and rear side walls of the fixed base, and a locking stud is movably inserted into the middle of the sliding column through the through hole. The locking stud passes through the two through slots, and a locking nut is threaded to the rear end of the locking stud.

[0007] Preferably, a scale line is provided on one side wall of the fixed seat, and a pointer is fixedly welded to the front side wall of the sliding column.

[0008] Preferably, a handwheel is fixedly installed at the top end of the precision screw.

[0009] Preferably, a connecting column is fixedly welded between the two mounting blocks.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention allows the precision screw to be rotated via a handwheel, which moves the sliding column on the fixed base. The sliding column, through two sliding rods, moves two mounting blocks up and down, thereby moving two stretching rollers up and down. This adjusts the distance between the stretching rollers and the fixed rollers, enabling simultaneous adjustment of the two stretching rollers inside the housing from outside the housing. This greatly improves the convenience of adjusting the two stretching rollers and enhances its practicality. After adjustment, the sliding column can be locked and fixed by the locking stud and locking nut, preventing accidental displacement of the sliding column and ensuring the stability of the two stretching rollers.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a stretching mechanism for PE film processing, comprising: The box body 1 is equipped with an adjustment mechanism 2. Two fixed rollers 3 are rotatably installed in the inner cavity of the box body 1. Each of the two fixed rollers 3 is equipped with a tension roller 4. The adjustment mechanism 2 includes a fixed seat 5, which is fixedly installed on the top wall of the box body 1. The fixed seat 5 has a sliding groove 10. A sliding column 6 is slidably connected in the sliding groove 10. Sliding rods 7 are fixedly welded to the bottom walls of both ends of the sliding column 6. The two sliding rods 7 are slidably connected in two through holes in the top wall of the box body 1. Mounting blocks 8 are fixedly welded to the bottom ends of the two sliding rods 7. The two tension rollers 4 are rotatably installed on the two mounting blocks 8 respectively. A precision screw 9 is rotatably installed in the middle of the top wall of the sliding column 6. The precision screw 9 is threadedly connected to the fixed seat 5.

[0015] Two aligned through slots 11 are provided on the front and rear side walls of the fixed base 5. A locking stud 12 is movably inserted into the middle of the sliding column 6 through the through hole. The locking stud 12 passes through the two through slots 11. A locking nut 13 is threaded to the rear end of the locking stud 12. Through the cooperation of the locking stud 12 and the locking nut 13, the sliding column 6 can be locked and fixed after adjustment to prevent the sliding column 6 from accidentally shifting.

[0016] A scale line 14 is provided on one side wall of the fixed base 5, and a pointer 15 is fixedly welded to the front side wall of the sliding column 6. The scale line 14 makes it easy to clearly define the adjustment position during adjustment.

[0017] A handwheel 16 is fixedly installed at the top of the precision screw 9, which facilitates the rotation of the precision screw 9 by turning the knob.

[0018] A connecting column 17 is fixedly welded between the two mounting blocks 8 to further ensure the synchronization of the two mounting blocks 8 during adjustment.

[0019] Working principle: In use, the precision screw 9 can be rotated by the handwheel 16, which drives the sliding column 6 to move on the fixed base 5. The sliding column 6 can drive the two mounting blocks 8 to move up and down through the two sliding rods 7, thereby driving the two stretching rollers 4 to move up and down. The distance between the stretching rollers 4 and the fixed roller 3 can be adjusted, which realizes the effect of simultaneously adjusting the two stretching rollers 4 inside the box 1 from the outside of the box 1. This greatly improves the convenience of adjusting the two stretching rollers 4 and makes it more practical. After the adjustment is completed, the sliding column 6 can be locked and fixed by the cooperation of the locking stud 12 and the locking nut 13 to prevent the sliding column 6 from accidentally shifting and to ensure the stability of the two stretching rollers 4.
