[0011] The film combining operation process is as follows: the first film combining component is started, the films on the left and right sides of the product are scraped and attached to the bottom of the product by the first film combining component, then the second film combining component is started, the films in front of and behind the product are scraped and attached to the bottom of the product by the second film combining component, so that the films in front of, behind, left and right of the product are all scraped and attached to the bottom of the product, and the film combining operation is completed.

[0012] Through the above film pulling and combining action arrangement, the film wrapping operation rhythm is strong, the components operate independently, the standby operation phenomenon is avoided, the interference and the standby phenomenon in the operation process are avoided, the operation rhythm is improved. Through the position layout arrangement between the film pulling mechanism and the film combining mechanism, the operation flow is improved, the overall structure is compact and reasonable, the occupied space is small, and the operation is convenient.

[0013] By arranging the width adjusting component, the straight line distance between the first film pulling component and the second film pulling component can be adjusted, that is, the width of the film can be flexibly adjusted according to the size of the product, the matching degree of the film and the product is effectively improved, and the phenomenon of waste of film material is also eliminated.

The first driving body is driven by the existing motor driving gear and gear belt technology to move the first sliding block. Through the setting, when the distance between the first film pulling component and the second film pulling component needs to be shortened, the first driving body is started to drive the first sliding block to move the second film pulling component on the first guide rail to the direction of the first film pulling component, so as to shorten the distance between the first film pulling component and the second film pulling component.

The second driving body is driven by the existing motor driving gear and gear belt. When the product is lifted to the film combining mechanism and stops against the film, the second driving body is started, so that the first film combining plate and the second film combining plate move towards each other on the first guide rail and the second guide rail, and the first film combining plate slides to the bottom surface of one side of the product, while the second film combining plate slides to the bottom surface of the other side of the product, so that the films on both sides of the product are attached to the bottom surface of the product, and the film combining on both sides is completed.

[0021] Further, the second film combining component comprises a third driving body, a second sliding block, a fourth guide rail, a third film combining plate and a film scraping roller; the third driving body drives the second sliding block to slide on the fourth guide rail; the two ends of the third film combining plate are respectively connected to the second sliding block; the film scraping roller is arranged above the third guide rail and is arranged in the same plane as the third film combining plate.

After the film combining of the first film combining component is completed, the third driving body is started, the third film combining plate moves forward, so that the film at the rear end of the product is attached to the bottom of the product, and when the product comes out, the film at the front end of the product is scraped by the film scraping roller, so that the film at the front end of the product is attached to the bottom of the product, and the film combining at the front and rear of the product is completed.

[0022] After the films on the left, right, front and rear of the product are attached to the bottom surface of the product by the above film combining mechanism, the first film combining component and the second film combining component are restored, i.e. the first film combining plate and the second film combining plate move away from each other, and the third film combining plate moves backward, so as to prepare for the film combining of the next product.

The heating element is provided with a constant temperature heating rod. Through the above arrangement, after the product film is combined, the product bottom is placed on the heating element, so that the film at the bottom of the product is heated and bonded, ensuring the tightness and firmness of the product packaging. The film sealing component is arranged at the front end of the first film combining component and the second film combining component, which facilitates the film combining after the film combining is completed, and improves the operation convenience.

[0024] Further, the film combining mechanism further comprises a film pressing component; the film pressing component is arranged above the second film combining component; the film pressing component comprises a pressing plate and a support frame, the support frame is fixedly connected to the upper end of the pressing plate, and the pressing plate is arranged between the first film combining component and the second film combining component. Through the above arrangement, before the film combining is performed, the product needs to be conveyed from bottom to top to the film combining mechanism, when the product rises to a certain height and contacts the pressing plate, it means that the product is in the appropriate position, and the product can stop rising. It can effectively prevent the product from rising too much and causing the film to separate from the film pulling mechanism, facilitating the subsequent film combining operation.
