It can be directly recycled and pulped to make paper. Replacing plastic with paper can reduce and lower environmental pollution. Food-grade transparent plastic substitute paper is one of the types of plastic substitute paper. In the production process of food-grade transparent plastic substitute paper, tensioning equipment is required to avoid wrinkles on food-grade transparent plastic substitute paper.

After the transparent paper roll is replaced, the tensioning mechanism is pushed to the top of the film guide mechanism, and one end of the transparent paper is passed between the tensioning mechanism and the film guide mechanism, and then the tensioning mechanism is lowered, so that the transparent paper can be adaptively tensioned by the gravity of the tensioning mechanism, and the operation is convenient.

[0004] Although the above-mentioned transparent paper tensioning device can solve the corresponding technical problems, when its tensioning mechanism pushes the top of the inverted film guide mechanism, it is necessary to manually support the tensioning mechanism so that one end of the transparent paper can pass through between the tensioning mechanism and the film guide mechanism. At least two people are needed to cooperate in the operation, and it is difficult for one person to operate, which increases the labor cost and high production cost. Utility Model Content

[0026] See attached Figure 1-Figure 4As shown, the tensioning device for plastic-substitute paper production according to the embodiment of the utility model includes a support 1, a guide mechanism 2 for guiding the plastic-substitute paper, a tensioning mechanism 3 for tensioning the plastic-substitute paper, a limiting mechanism 4 for guiding the tensioning mechanism 3, a pushing component 5 for pushing the tensioning mechanism 3 to move, and a locking component 6 for positioning the pushing component 5.

[0027] The guide mechanism 2 and the tensioning mechanism 3 are arranged on one side of the support 1 from top to bottom, the limiting mechanism 4 is arranged between the support 1 and the tensioning mechanism 3, the pushing assembly 5 is arranged on the limiting mechanism 4, and the locking assembly 6 is arranged on the side of the support 1 away from the tensioning mechanism 3.

[0028] The pushing assembly 5 includes a push rod 51 movably arranged on the support 1 . The support 1 is provided with a sliding hole 11 for the push rod 51 to slide. A handle 52 is fixedly connected to one side of the push rod 51 away from the tensioning mechanism 3 .

[0029] The locking assembly 6 includes two shifting blocks 61 symmetrically arranged about the central axis of the support 1, and the two shifting blocks 61 are fixedly connected to the opposite sides with positioning columns 62. The surface of the handle 52 is provided with a positioning groove 521 adapted to the positioning column 62, and a telescopic member is provided between the shifting blocks 61 and the support 1.

[0030] See attached Figure 4 As shown, the telescopic member includes a guide column 63 movably penetrating the shift block 61, both ends of the guide column 63 are fixedly connected with support blocks 64, one side of the support block 64 is fixedly connected to the support 1, and the guide column 63 and the support block 64 cooperate to guide the shift block 61, so that the shift block 61 can stably move along the axial direction of the guide column 63.

[0031] See attached Figure 4 As shown, a spring 65 is sleeved on the surface of the guide column 63, and both ends of the spring 65 are fixedly connected to the corresponding shift block 61 and support block 64 respectively. Through the elastic force of the spring 65, the shift block 61 and the positioning column 62 are automatically reset, which is convenient for the next positioning operation.

[0032] See attached Figure 4 As shown, the handle 52 is spherical in structure. When the handle 52 is moved upward with force, the arc structure on the surface of the handle 52 can apply pressure to the two positioning columns 62, so that the two positioning columns 62 can move oppositely under the force. There is no need to manually push the two shifting blocks 61 apart, thereby improving the positioning efficiency of the guide mechanism 2.

[0033] See attached Figure 1-Figure 2As shown, the guide mechanism 2 includes a first support plate 21 arranged parallel to the support 1, and the first support plate 21 is rotatably connected to the upper part of one side of the support 1 with multiple equidistantly distributed second support plates 22, and guide rollers 23 are installed on both sides of the first support plate 21, and one side of the guide roller 23 is fixedly connected to the support 1.

[0034] See attached Figure 1-Figure 2 As shown, the tensioning mechanism 3 includes a third support plate 31 movably connected to one side of the support 1, and one side of the third support plate 31 is rotatably connected to a plurality of equally spaced tensioning rollers 32, and the tensioning rollers 32 and the second support plate 22 are staggered.

[0035] See attached Figure 1 and Figure 3 As shown, the limiting mechanism 4 includes a slide seat 41 slidably connected to the inner cavity of the support 1, and the two sides of the slide seat 41 are fixedly connected to the third support plate 31 and the push rod 51 respectively. A guide rod 42 is movably provided through the inner cavity of the slide seat 41, and both ends of the guide rod 42 are fixedly connected to the support 1. Through the coordinated use of the slide seat 41 and the guide rod 42, a guiding effect is played on the tensioning mechanism 3, so that the tensioning mechanism 3 can stably move along the axial direction of the guide rod 42.

[0036] After the plastic paper roll is replaced, the handle 52 is pushed upward, and the handle 52 drives the positioning groove 521, the push rod 51, the slide seat 41, the third support plate 31 and the tensioning roller 32 to move upward synchronously. The slide seat 41 slides on the surface of the guide rod 42, and the push rod 51 slides in the inner cavity of the slide hole 11. When the handle 52 moves to a certain distance, the surface of the handle 52 squeezes the positioning column 62, and the two positioning columns 62 move synchronously in opposite directions. The positioning column 62 drives the shift block 61 to slide on the surface of the corresponding guide column 63, and the shift block 61 compresses the spring 65 until the handle 52 is moved to a certain distance. 2 is moved to the maximum extent so that the tensioning mechanism 3 is located above the guide mechanism 2. At this time, the elastic restoring force of the spring 65 causes the positioning column 62 to be stuck in the inner cavity of the corresponding positioning groove 521, so that the handle 52 can be positioned, thereby making the pushing component 5, the slide seat 41 and the tensioning mechanism 3 stably maintained at this position, and then one end of the plastic-substitute paper can be passed through between the guide mechanism 2 and the tensioning mechanism 3, and the two shifting blocks 61 are shifted back to back to unlock the handle 52. Finally, the handle 52 can be held to slowly move the guide mechanism 2 down to the original position.

[0037] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
