[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes. Example
[0026] See also Figure 1 to Figure 5 In this embodiment, a PVA starch-based food degradable film cutting device is provided, comprising a bottom plate 1, a plurality of supporting legs 2 are installed at the bottom of the bottom plate 1, a buffer pad is arranged at the bottom of the supporting leg 2, which can play a buffering effect during operation and has a silent and shock-absorbing effect, and a cutting table 3 is also installed at the middle position of the upper end of the bottom plate 1, the cutting table 3 provides a support platform for cutting the film, and a cutting slit is arranged at the center of the upper end of the cutting table 3, so that the cutter can fall better and will not collide with the cutting table 3, thereby protecting the cutter;
[0027] A smoothing mechanism 4 is provided on the outer side of the cutting table 3. When the film is waiting to be cut, it is first smoothed on the cutting table 3 by the smoothing mechanism 4 to avoid wrinkles or folds, thereby avoiding affecting the cutting quality. The smoothing mechanism 4 is covered on the cutting table 3 and can smooth the film from the middle to both sides.
[0028] A cutting assembly 5 is also provided at the rear side of the cutting table 3 at the upper end of the bottom plate 1. The cutting assembly 5 is used to complete the cutting operation of the film. In addition, a ruler 6 is provided on the side wall of the cutting table 3. The ruler 6 can measure the film to be cut, making the cutting of the film more convenient. There is no need to measure the film again before cutting. The film can be directly measured by the ruler 6 while being pulled, which is convenient to operate.
[0029] It should be noted that the upper end of the bottom plate 1 located on the left and right sides of the cutting table 3 can be provided with a material receiving or unwinding structure for winding, which is a conventional structural setting and is not the focus of the present application, so it is omitted in the drawings, and the conventional prior art can be used;
[0030] Specifically, the cutting assembly 5 includes a support rod 51, the bottom of the support rod 51 is fixed to the upper end of the bottom plate 1, a top plate 52 is arranged at the bottom of the support rod 51, a hydraulic rod 53 is installed at the lower side of the front end of the top plate 52, a cutting knife 54 is arranged at the bottom of the hydraulic rod 53, and the cutting knife 54 is located just above the cutting slit at the upper end of the cutting table 3, and the two correspond to each other. When the hydraulic rod 53 drives the cutting knife 54 to move downward to cut the film, the blade just falls into the cutting slit to protect the cutting knife 54. After cutting, the hydraulic rod 53 moves upward to restore the cutting knife 54 to its original position and wait for the next operation.
[0031] The smoothing mechanism 4 includes a mounting plate 41, two mounting plates 41 are provided, which are located at the front and rear sides of the cutting table 3 and fixed on the side wall of the cutting table 3, a slide groove 42 is provided in the mounting plate 41, a bidirectional screw rod 43 is installed in the slide groove 42, a partition plate 45 is provided in the middle of the bidirectional screw rod 43, which distinguishes the threads on both sides of the bidirectional screw rod 43, the bidirectional screw rod 43 is rotatably connected to the inner wall of the mounting plate 41, and a motor 44 is also installed at one end of the bidirectional screw rod 43, the motor 44 is fixed to the outer wall of the mounting plate 41 through the motor plate, and after the motor 44 is started, it can drive the bidirectional screw rod 43 to rotate in the slide groove 42;
[0032] Threaded slides 46 are provided on two different threaded sections of the bidirectional screw 43. The threaded slides 46 are slidably connected to the inner wall of the slide groove 42. When the bidirectional screw 43 is driven to rotate by the motor 44, the threaded slides 46 thereon will slide in the slide groove 42, and they slide close to each other or away from each other. Initially, they are located at the center of the cutting table 3, that is, the two threaded slides 46 are close to each other. To achieve the smoothing effect, the two slide away from each other under the action of the motor 44 and the bidirectional screw 43, so that the film can be smoothed from the center to both sides.
[0033] An electric push rod 47 is arranged at the upper end of each threaded slide 46, and a smoothing roller 48 is installed at the top between the electric push rods 47 symmetrically arranged on the front and rear sides. The smoothing roller 48 can realize self-rotation, which can reduce the friction between the smoothing roller 48 and the film and realize a certain degree of protection for the film. Initially, the electric push rod 47 is extended, which drives the smoothing roller 48 to move upward, and forms a space between the smoothing roller 48 and the cutting table 3 so that the film can pass through. When in use, the electric push rod 47 is shortened;
[0034] The setting of the ruler 6 can conveniently measure the length of the film when it is cut. The ruler 6 includes an outer ruler 61 and an inner ruler 63. The outer ruler 61 is fixed on the front side wall of the cutting table 3 for easy observation by the user. An inner groove 62 is set in the outer ruler 61, and an inner ruler 63 is set in the inner groove 62. The two are slidably connected, and then the inner ruler 63 can be pulled out from the inner part of the outer ruler 61, thereby increasing the measuring range of the entire ruler 6. When not in use, it can also be retracted into the outer ruler 61 without taking up too much space.
[0035] A limit block 64 is also provided at the outer end of the inner ruler 63 to prevent the inner ruler 63 from completely entering the outer ruler 61, thereby achieving a limit protection effect. At the same time, the outer ruler 61 and the inner ruler 63 are fixed by a fastener 65. The fastener 65 can be a screw. When tightened, the inner ruler 63 is fixed to prevent it from sliding. Conversely, when it is loosened, the position of the inner ruler 63 can be adjusted to increase or shorten the measuring range for easy use.
[0036] In the utility model, a smoothing mechanism 4 is installed on the peripheral side of the cutting table 3, which can smooth the film to be cut before cutting, avoiding the problem of unevenness at the cutting position, and also avoiding wrinkles or folds, thereby ensuring the quality of the film cutting operation. Moreover, through the directly installed ruler 6, the film length can be measured in real time, making the cutting operation more convenient.
[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
