It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, the origin stretching device of this embodiment includes a machine base 1, four clamps 2, a lateral moving structure 3, a longitudinal moving structure 4, a first support plate 5 and a second support plate 6, the two ends of the first support plate 5 are slidably arranged on both sides of the machine base 1, the two ends of the second support plate 6 are slidably arranged on the other two sides of the machine base 1 and are perpendicular to the first support plate 5, the lateral moving structure 3 is installed on the left side of the machine base 1, and its moving end is connected to the first support plate 5, the longitudinal moving structure 4 is installed on the front side of the machine base 1, and its moving end is connected to the second support plate 6, two of the four clamps 2 are fixed on the right side and the rear side of the machine base 1, and the other two are respectively installed on the first support plate 5 and the second support plate 6, the front ends of the four clamps 2 surround a square area, and the four clamps 2 are located on the same horizontal plane. During operation, four clamps 2 clamp the film material, the clamps 2 located on the right and rear sides of the base 1 remain stationary, and the transverse moving structure 3 drives the first support plate 5 to move transversely on the base 1, driving the clamps 2 located on the first support plate 5 to stretch the film transversely. At the same time, the longitudinal moving structure 4 drives the second support plate 6 to move longitudinally on the base 1, driving the clamps 2 located on the second support plate 6 to stretch the film longitudinally, so that the origin of the film remains stationary but is stretched to the left and front sides, achieving good stretching efficiency. At the same time, only two directions of stretching are required, and the entire stretching device only needs two moving structures, the structure is simpler, and control is convenient, which is conducive to improving the stretching quality.

[0024] In this embodiment, since the structures of the longitudinal moving structure 4 and the transverse moving structure 3 are the same, but the moving directions and the objects of action are different, the longitudinal moving structure 4 drives the second support plate 6 to move longitudinally, and the transverse moving structure 3 drives the first support plate 5 to move transversely. Here, only the transverse moving structure 3 is described. The transverse moving structure 3 includes a first motor 31 and a first screw rod 32. The first motor 31 is installed on the left side of the base 1. One end of the first screw rod 32 passes through the left side of the base 1 and is connected to the first motor 31 in a transmission manner, and the other end is threadedly connected to the first support plate 5. A nut can be welded on the first support plate 5, and the other end of the first screw rod 32 is screwed with the nut to form a threaded connection. When working, the first motor 31 rotates, driving the first screw rod 32 to rotate, prompting the first support plate 5 to move transversely, and driving the clamp on the first support plate 5 to stretch the film transversely. The transverse moving structure 3 and the longitudinal moving structure 4 can also adopt other structures, as long as the first support plate 5 and the second support plate 6 can be driven to move.

[0025] In this embodiment, if Figure 2 , Figure 3 As shown, the clamp 2 includes an upper clamp plate 21, a lower clamp plate 22, a spring piece 23, a movable column 24, and a pressure plate 25. The lower clamp plates 22 of two of the four clamps 2 are respectively fixed to the right side and the rear side of the machine base 1, and the lower clamp plates 22 of the other two are respectively fixed to the first support plate 5 and the second support plate 6. The upper clamp plate 21 is fixed to the lower clamp plate 22, and a pressure cavity 26 is formed between the front ends of the upper clamp plate 21 and the lower clamp plate 22. The pressure plate 25 is placed in the pressure cavity 26. The movable column 24 vertically penetrates the front end of the upper clamp plate 21, and its lower end is fixed to the pressure plate 24, and its upper end extends out of the upper clamp plate 21. The spring piece 23 is fixed to the upper clamp plate 21, and its front end is pressed on the upper end of the movable column 24. When clamping a film or other material, the pressing plate 25 is pushed upward, and the film or other material is placed between the pressing plate 25 and the lower clamping plate 22. The movable column 24 is moved downward by the force of the spring sheet 23 to drive the pressing plate 25 to press the film onto the lower clamping plate 22, which can quickly achieve the clamping function and effectively avoid the problems of complex structure caused by the traditional pneumatic clamps relying on external pneumatic systems, making the clamp more convenient and effective to use. When releasing the film, the pressing plate 25 is pushed upward, and the film is taken out from between the pressing plate 25 and the lower clamping plate 22.

[0026] In this embodiment, the clamp 2 further includes a top column 27 and a swing rod 28. The top column 27 vertically passes through the front end of the upper clamping plate 21, and its upper end presses against the bottom of the pressing plate 25. The middle part of the swing rod 28 is hinged to the bottom of the lower clamping plate 22, and the top of its front end presses on the lower end of the top column 27. The swing rod 28 drives the top column 27 to move upward to push open the pressing plate 25, so as to facilitate the placement of materials such as films between the pressing plate 25 and the lower clamping plate 22. The front end shaft of the swing rod 28 is provided with a pulley 29, and the lower end of the top column 27 presses on the pulley 29, so that the lower end of the top column 27 and the pulley 29 are in sliding contact, reducing the friction between the two, which is conducive to the swing rod 28 driving the top column 27 to move upward. The front end of the lower clamping plate 22 is vertically provided with a first through hole 210, and the top column 27 is slidably arranged in the first through hole 210, so as to facilitate the vertical movement of the top column 27. The front end of the upper clamping plate 21 is vertically provided with a second through hole 211, and the movable column 24 is slidably arranged in the second through hole 211, so as to facilitate the vertical movement of the movable column 24. In order to enable the pressing plate 25 to better press the film, the bottom of the pressing plate 25 and the top of the lower clamping plate 22 are both provided with pressing teeth.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
