Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a bidirectional synchronous stretching and strengthening device for plastic films. Background Technology

[0002] Plastic film is a film made of plastic materials and can be used to produce plastic bags and express delivery bags. After biaxial stretching, the tensile strength and elastic modulus of plastic film are significantly increased, and the mechanical strength is significantly improved. Therefore, it is necessary to use a biaxial synchronous stretching strengthening device to stretch plastic film to improve the toughness of plastic bags and express delivery bags.

[0003] Common biaxial synchronous tensile strengthening devices for plastic films still have some problems in use. For example, after stretching, the plastic film needs to be stored, but the storage stability of the plastic film is poor, and it is easy for the plastic film to slip accidentally, affecting the storage and stretching effect.

[0004] Therefore, we propose a biaxial synchronous tensile strengthening device for plastic films to improve the above-mentioned problems. Utility Model Content

[0007] The stable storage structure includes a worm gear, a first motor, and a second motor. Two sets of fixing plates are provided. A first protective shell and a second protective shell are fixedly connected to the front end of each fixing plate. A first motor is installed on the left side of the bottom end of the first protective shell, and a second motor is installed on the left side of the bottom end of the second protective shell.

A mounting shaft is movably connected between the fixing plate and the rear plate. Placement rollers and storage rollers are respectively provided outside the mounting shaft. A worm gear is fixedly connected to the rear end of the mounting shaft.

[0010] As a further technical solution of this utility model, the limiting plate is disposed at the bottom end of the movable pressure plate, and the limiting plate and the movable pressure plate cooperate with each other.

[0014] (1) By setting up a first protective shell, a worm gear, a mounting shaft, a first motor, a second motor and a placement roller, start the first motor on the left side of the bottom of the first protective shell. The first motor drives the mounting shaft to rotate through the worm and worm gear to unwind the plastic film outside the placement roller.

When it is necessary to stretch the plastic film laterally, the second servo motor is started, the second servo motor drives the first bidirectional screw to rotate, the first threaded sleeve drives the base plate to move outward through the connecting block to stretch the plastic film laterally.

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.

[0023] Please see Figure 1-4The present invention provides an embodiment of a bidirectional synchronous tensile strengthening device for plastic film, comprising a workbench 1, four corners at the bottom of the workbench 1 fixedly connected to support legs 4, a base plate 6 on the left and right sides at the top of the workbench 1, a fixing plate 7 fixedly connected to the front end of the top of the base plate 6, a connecting seat 19 fixedly connected to the middle position at the top of the workbench 1, and a stable storage structure provided at the front end of the fixing plate 7.

[0024] The stable storage structure includes a worm gear 9, a first motor 13 and a second motor 14. The fixing plate 7 is provided with two sets. The front end of the fixing plate 7 is fixedly connected to the first protective shell 8 and the second protective shell 18 respectively. The first motor 13 is installed on the left side of the bottom end of the first protective shell 8, and the second motor 14 is installed on the left side of the bottom end of the second protective shell 18. The output ends of the second motor 14 and the first motor 13 are fixedly connected to the worm gear 28 respectively. The rear end of the top of the bottom plate 6 is installed with a rear plate 27. The fixing plate 7 and the rear plate 27 are movably connected to the mounting shaft 10. The outside of the mounting shaft 10 is provided with a placement roller 26 and a storage roller respectively. The rear end of the outside of the mounting shaft 10 is fixedly connected to the worm gear 9.

[0025] The worm gear 9 is located on one side of the worm 28, and the worm gear 9 and the worm 28 cooperate with each other;

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first motor 13 on the left side of the bottom of the first protective shell 8 is started. The first motor 13 drives the mounting shaft 10 to rotate through the worm 28 and worm wheel 9, so that the plastic film outside the placement roller 26 is unwound. The worm 28 and worm wheel 9 can also prevent the mounting shaft 10 from rotating accidentally when the plastic film is pulled laterally. When the plastic film is stretched, the second servo motor 17 and the second motor 14 are started at the same time. The second motor 14 drives the take-up roller outside the mounting shaft 10 to take in the stretched plastic film through the worm 28 and worm wheel 9.

[0027] Connecting plates 15 are provided at the front and rear ends of the top of the connecting seat 19. A support frame 11 is fixedly connected to the top of the connecting plate 15. A hydraulic cylinder 12 is installed at the top inside the support frame 11. A movable pressure plate 20 is installed at the bottom of the hydraulic cylinder 12. A limit plate 21 is fixedly connected to the middle end of the support frame 11. An anti-slip pad 22 is fixedly connected to the middle end of the limit plate 21 and the movable pressure plate 20. The limit plate 21 is located at the bottom of the movable pressure plate 20. The limit plate 21 and the movable pressure plate 20 cooperate with each other.

[0028] Specifically, such as Figure 1 and Figure 2As shown, when the support frame 11 moves the limiting plate 21 to the appropriate position, the hydraulic cylinder 12 is activated. The hydraulic cylinder 12 drives the movable pressure plate 20 to descend, so that the movable pressure plate 20 abuts against the top of the limiting plate 21 to limit and fix the plastic film. Limiting and fixing the plastic film can prevent the plastic film from accidentally slipping when stretching the plastic film longitudinally.

[0029] A second servo motor 17 is installed on the right side of the workbench 1. A first bidirectional screw 2 is fixedly connected to the output end of the second servo motor 17. A first threaded sleeve 3 is provided on the left and right sides of the outside of the first bidirectional screw 2. A connecting block 5 is fixedly connected between the first threaded sleeve 3 and the base plate 6. A first servo motor 16 is installed at the front end of the connecting seat 19. A second bidirectional screw 23 is fixedly connected to the output end of the first servo motor 16. A second threaded sleeve 24 is provided at the front and rear ends of the outside of the second bidirectional screw 23. A movable block 25 is fixedly connected between the second threaded sleeve 24 and the connecting plate 15.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, when the plastic film needs to be stretched longitudinally, the first servo motor 16 is started. The first servo motor 16 drives the second bidirectional screw 23 to rotate. The rotation of the second bidirectional screw 23 can cause the second threaded sleeve 24 to drive the support frame 11 to move outward, thus stretching the plastic film longitudinally. When the plastic film needs to be stretched laterally, the second servo motor 17 is started. The second servo motor 17 drives the first bidirectional screw 2 to rotate, causing the first threaded sleeve 3 to drive the base plate 6 to move outward through the connecting block 5, thus stretching the plastic film laterally.

[0031] Working principle: When this utility model is in use, the support frame 11 moves the limiting plate 21 to a suitable position, and the hydraulic cylinder 12 is activated. The hydraulic cylinder 12 drives the movable pressure plate 20 to descend, so that the movable pressure plate 20 abuts against the top of the limiting plate 21 to limit and fix the plastic film. Limiting and fixing the plastic film can prevent the plastic film from accidentally slipping when stretching the plastic film longitudinally. The first motor 13 on the left side of the bottom of the first protective shell 8 is activated. The first motor 13 drives the mounting shaft 10 to rotate through the worm 28 and worm wheel 9, so that the plastic film outside the placement roller 26 is unwound. When it is necessary to stretch the plastic film longitudinally, the first servo motor 16 is activated. The first servo motor 16 drives the second bidirectional screw 23 to rotate. The rotation of the second bidirectional screw 23 can make the first The threaded sleeve 24 drives the support frame 11 to move outward, stretching the plastic film longitudinally. When the plastic film needs to be stretched laterally, the second servo motor 17 is activated. The second servo motor 17 drives the first bidirectional screw 2 to rotate, causing the first threaded sleeve 3 to drive the base plate 6 to move outward through the connecting block 5, stretching the plastic film laterally. After stretching, the second servo motor 17 is activated again, driving the first bidirectional screw 2 to rotate, bringing the base plate 6 closer to the middle end. The second motor 14 is then activated. The second motor 14 drives the take-up roller outside the mounting shaft 10 through the worm 28 and worm wheel 9 to collect the stretched plastic film. The worm 28 and worm wheel 9 also prevent the mounting shaft 10 from rotating accidentally when the plastic film is stretched laterally.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
