When the left clamping block 131 moves to the right and the right clamping block 132 moves to the left, the clamping mechanism 13 is in a "closed" state, at which time the product is fixed and clamped. On the contrary, when the left clamping block 131 moves to the left and the right clamping block 132 moves to the right, the clamping mechanism 13 is in an "open" state, at which time the product is released.

[0029] The two sides of the conveying mechanism 11 are provided with a cutting mechanism 14, and the cutting mechanism 14 includes a cutting bottom plate 15 that can move toward the suction plate 12, and the cutting bottom plate 15 is provided with a fourth cylinder 151 for driving the cutting bottom plate 15 to move toward the conveying mechanism 11.

Specifically, the rear end of the bottom lining block 16 is provided with a cylinder for driving it to press downward. The fifth cylinder 161 of the film is preferably provided with a set of third slide rails 162 and an upper slider 163 at the rear end of the bottom lining block 16 in order to realize the downward sliding action. The bottom lining block 16 is arranged at the front end of the upper slider 163. The right corner lining block 17 and the left corner lining block 18 are respectively arranged on both sides of the bottom lining block 16. The rear ends of the right corner lining block 17 and the left corner lining block 18 are provided with a sixth cylinder 181 for driving both to move downward at the same time.

It is preferred that The bottom liner block 16 slides between the right corner liner block 17 and the left corner liner block 18. The shape of the bottom liner block 16 gradually narrows from top to bottom. When the right corner liner block 17 and the left corner liner block 18 are fitted together, a bayonet 186 matching the shape of the bottom liner block 16 is formed, so that the bottom liner block 16 can be quickly inserted between the right corner liner block 17 and the left corner liner block 18 to avoid jamming. A lower sealing and cutting knife 19 is provided below the bottom liner block 16, a right sealing and cutting knife 20 is provided on the right side of the right corner liner block 17, and a left sealing and cutting knife 21 is provided on the left side of the left corner liner block 18.

[0030] As a further step of the above embodiment, in order to better cut the left corner and the right corner of the product, the two corner cutting mechanisms 14 are diagonally arranged, so that the distance between the corner cutting mechanism 14 and the conveying mechanism 11 can be adjusted according to the size of different products. The clamping mechanism 13 is provided with two, and the two clamping mechanisms 13 are arranged in sequence above the suction plate 12. The two clamping mechanisms 13 are respectively arranged corresponding to the two corner cutting mechanisms 14. Support frames 22 are provided on both sides of the suction plate 12, and mounting cross plates 23 are provided between the support frames 22, and the second cylinder 133 is provided on the mounting cross plate 23.

[0031] The specific implementation is as follows: before processing, the limiting shaft 31 with the film roll is embedded in the slide groove 35, at which time the bottom of the film roll abuts against the load-bearing shaft 32, and the film on the film roll passes through the two load-bearing shafts, between the film feeding glue shaft 33 and the film feeding driven wheel 34 in sequence, and the film feeding port 41 reaches the bottom of the processing pad 4. Preferably, in order to reduce the wrinkles of the film and make it easier for the film to adhere to the product, a film collecting glue shaft 27 and a film collecting driven wheel 28 connected to the film are provided under the processing pad 4. After the film passes through the film feeding port 41, it passes between the film collecting glue shaft 27 and the film collecting driven wheel 28. During operation, the product is placed on the conveyor belt 6. After the conveyor belt 6 conveys the product to the lifting bottom plate 25, the lifting bottom plate 25 rises to the same level as the processing pad 4. At the same height of the pad 4, at this time, the push plate 7 moves toward the processing pad 4 under the drive of the third cylinder 61, and then the push plate 7 pushes the product from the lifting bottom plate 25 to the processing pad 4, and then passes through the film feeding port 41 and the cutting port 42 to reach the platform plate 9. At this time, since the product passes through the film feeding port 41, the pressure plate 10 above the platform plate 9 drops and abuts against the upper end of the product to fix the product. At this time, the platform plate 9 compensates for the width of the product by moving, and the sealing and cutting knife assembly 5 moves upward through the cutting port 42 to perform the first sealing and cutting of the film. At this time, the outer surface of the product is wrapped with a film, and then one end of the suction plate 12 moves forward to the bottom of the platform plate 9, and then rises upward to fix the product by vacuum adsorption. After that, it moves backward to the bottom of the clamping mechanism 13. The clamping mechanism 13 fixes the two ends of the product through the action of the left and right clamping plates. On the other hand, it can make the film closer to the product for the subsequent corner cutting work. At this time, the cutting bottom plate moves in the direction of the suction plate 12. First, the sixth cylinder 181 drives the entire lower slide plate 183 to move in the direction of the product. At this time, the right corner pad 17 and the left corner pad 18 are in a close contact state under the action of the spring. The downward movement of the entire lower slide plate 183 causes the right corner pad 17 and the left corner pad 18 to move downward at the same time, so that the excess film on the upper end surface of the product is pressed down. At the same time, when the right corner pad 17 and the left corner pad 18 move down to the appropriate position at the same time, the corner cutting bottom plate The plate 15 can move toward the product direction according to the actual width of the product. At this time, the right corner pad 17 and the left corner pad 18 are close to one end of the product, so that the excess film on the upper end surface of the product is close to one end of the product. Furthermore, under the drive of the fifth cylinder 161, the upper slider 163 drives the bottom pad 16 to move downward. At this time, due to the effect of negative pressure, the output shaft of the fifth cylinder 161 moves up at the same speed during the downward movement. At this time, the right corner pad 17 and the left corner pad 18 are always close to one end of the product. During the downward movement, the bottom pad 16 gradually passes through the bayonet 186 formed between the right corner pad 17 and the left corner pad 18. At this time, the right corner pad 17 moves to the right.The excess film on the upper end surface of the product and the excess film on the right end surface of the product are folded into the right corner. At the same time, the left corner pad 18 moves to the left, and the excess film on the upper end surface of the product and the excess film on the right end surface of the product are folded into the left corner. Furthermore, the right sealing and cutting knife 20 moves toward the right corner pad 17 to cut off the right corner, and the corresponding left sealing and cutting knife 21 moves toward the left corner pad 18 to cut off the left corner. The lower sealing and cutting knife 19 moves upward to cut off the excess film on the lower end surface of the product. Due to the stickiness of the film, the film on the product after the excess film is cut off automatically adheres together to form a complete film lamination and corner cutting work. The degree of automation is high, which reduces the intervention of operators and improves economic benefits.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
