[0019] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0020] Embodiment 1

[0021] As Figures 1 to 4 shown, the film stretcher with thickness measuring function in this embodiment includes a base 1, a stretching mechanism 2, a thickness measuring mechanism 3, a transverse moving mechanism 4 and an oven 5. A transverse operation channel 11 is provided on the base 1. A guide rail 12 is horizontally installed in the operation channel 11. The stretching mechanism 2 is slidably installed on the guide rail 12. The transverse moving mechanism 4 is installed on the base 1, and its moving end is connected to the stretching mechanism 2 and drives the stretching mechanism 2 to slide along the guide rail 12. The thickness measuring mechanism 3 is installed on the base 1 and is located above and below the stretching mechanism 2. The oven 5 is installed on the base 1 and is located on the right side of the stretching mechanism 2. Among them, the transverse moving mechanism 4 is a common mechanism for driving the stretching mechanism 2 to move transversely. During operation, after the stretching mechanism 2 stretches the film, the thickness measuring mechanism 3 measures the thickness of the film. The stretching mechanism 2 moves to the oven 5 under the drive of the transverse moving mechanism 4 for heating the film. The film stretcher with thickness measuring function in this embodiment uses the thickness measuring mechanism to measure the thickness of the film stretched by the stretching mechanism, avoiding the traditional manual measurement of the film thickness, and can effectively improve the production efficiency.

[0022] In this embodiment, the thickness measuring mechanism 3 includes two thickness measuring units 31. Each thickness measuring unit 31 includes four support columns 311, a cross beam 312, and a probe 313. The four support columns 311 of the two thickness measuring units 31 are respectively installed at the bottom and top of the machine base 1. The cross beam 312 is installed on the four support columns 311, and the probe 313 is installed on the cross beam 312. The probes 313 of the two thickness measuring units 31 are arranged opposite to each other and are located on the upper side and lower side of the stretching mechanism 2. The thickness of the film on the stretching mechanism 2 can be measured by using the two probes 313. The thickness measuring unit 31 further includes a lifting cylinder 314. The cross beam 312 is vertically slidably installed on the support columns 311. The lifting cylinder 314 is installed on the machine base 1, and its telescopic end is connected upward to the cross beam 312, which facilitates the up and down movement of the probe 313. After thickness measurement is completed, it can be raised to facilitate the stretching mechanism 2 to drive the film to the oven 5.

[0023] In this embodiment, a slider 13 is provided at the bottom of the stretching mechanism 2. The slider 13 is slidably installed on the guide rail 12. The cooperation between the slider 13 and the guide rail 12 facilitates the movement of the stretching mechanism 2 on the operation channel 11. There are two groups of ovens 5, and the two ovens 5 are symmetrically located on the upper side and lower side of the operation channel 11 to uniformly heat the upper and lower sides of the film.

[0024] In this embodiment, the stretching mechanism 2 includes a support machine base 21, two horizontal guide rails 22, two vertical guide rails 23, a first driving mechanism 24, a second driving mechanism 25, four chute plates 26, a plurality of clips 27, and four telescopic hinges 28. The support machine base 21 is slidably disposed on the guide rail 15 and is connected to the moving end of the lateral moving mechanism 3. The two horizontal guide rails 22 and the two vertical guide rails 23 are perpendicular to each other. The first driving mechanism 24 is installed on the support machine base 21, and its driving ends are respectively connected to the two horizontal guide rails 22 and drive the two horizontal guide rails 22 to move towards or away from each other. The second driving mechanism 25 is installed on the support machine base 21, and its driving ends are respectively connected to the two vertical guide rails 23 and drive the two vertical guide rails 23 to move towards or away from each other. The chute plate 26 is provided with a horizontal through hole 261 and a vertical through hole 262. The chute plate 26 is respectively slidably sleeved on two adjacent horizontal guide rails 22 and vertical guide rails 23 through the horizontal through hole 261 and the vertical through hole 262. The two ends of the telescopic hinge 28 are respectively hinged to two adjacent chute plates 26. The clip 27 is installed at the outer end of the telescopic hinge 28 and on the chute plate 26.

[0025] The first driving mechanism 24 and the second driving mechanism 25 are activated to drive the two transverse guide rails 22 and the two longitudinal guide rails 23 to move towards or away from each other respectively. Since the four chute plates 26 are sleeved on the adjacent transverse guide rails 22 and longitudinal guide rails 23 through the transverse through holes 261 and longitudinal through holes 262, the movement of the two transverse guide rails 22 and the two longitudinal guide rails 23 towards or away from each other drives the four chute plates 26 to move. The telescopic hinge 28 fixed between the two chute plates 26 moves accordingly, and the clips 27 installed at the outer ends of the telescopic hinge 28 and on the chute plates 26 move simultaneously to stretch the four sides and corners of the film, making the force on the film uniform during the stretching process and ensuring the stretching quality of the film. The first driving mechanism 24 and the second driving mechanism 25 can adopt a combination of a lead screw and a slider, or a combination of a pulley and a connecting block.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
