DETAILED DESCRIPTION

[0016] The present invention can be explained in detail by the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with Figures 1 to 5 A suitcase blank shaping device comprises a bracket, a collecting box 3, a hydraulic cylinder 7, a lower mold 11, an upper mold 5 and a cutting assembly 8. The bracket is composed of a fixed frame 1 and a supporting plate 2. A supporting plate 2 is provided on one side of the upper end of the fixed frame 1. A collecting box 3 is provided below the supporting plate 2. The upper end of the collecting box 3 is an open structure. A lower mold 11 is provided in the collecting box 3. An upper mold 5 is provided above the lower mold 11. The lower mold 11 is matched with the upper mold 5. A cutting assembly 8 is provided in the upper mold 5. A hydraulic cylinder 7 is provided on the supporting plate 2. The piston of the hydraulic cylinder 7 passes through the supporting plate 2 and is connected to the upper end of the upper mold 5. The hydraulic cylinder 7 drives the roller upper mold 5 and the cutting assembly 8 to move up and down.

[0018] The four corners of the lower surface of the lower mold 11 are provided with support rods 12 , the lower ends of the support rods 12 are connected to the bottom surface of the inner wall of the collection box 3 , and the suitcase blank is sleeved on the lower mold 11 .

[0019] The inner wall of the collecting box 3 is provided with a blade 13 , the blade 13 having its edge facing upwards. A box door 4 is provided on one side of the collecting box 3 , and exhaust holes 10 are distributed on the side of the collecting box 3 .

[0020] A collecting plate 14 is provided on the bottom surface of the inner wall of the collecting box 3, and one end of the collecting plate 14 close to the box door 4 is hinged to the bottom surface of the inner wall of the collecting box 3. A pull rod 15 is provided on the upper end surface of the collecting plate 14, and one end of the pull rod 15 is hinged to the end of the collecting plate 14 away from the box door 4. A handle 16 is provided on the other end of the pull rod 15. Pulling the handle 16 drives the end of the collecting plate 14 to lift up, so that the crushed suitcase scraps slide down to the end of the box door 4.

[0021] The upper mold 5 is opened downward, and a connecting rod 20 is provided on the upper surface of the upper mold 5. A sleeve 21 is sleeved on the connecting rod 20. The upper end of the sleeve 21 is connected to the lower end of the piston of the hydraulic cylinder 7. Four through grooves 18 are distributed on the upper surface of the upper mold 5. Two adjacent through grooves 18 are vertically arranged. Limiting grooves 19 are symmetrically distributed on the side of the upper mold 5. A limiting rod 6 is distributed on the upper end surface of the upper mold 5. The upper end of the limiting rod 6 passes through the support plate 2 and is slidably connected to the support plate 2.

[0022] The top surface of the inner wall of the upper mold 5 is provided with an anti-skid pad 17, which is arranged just above the lower mold 11. The anti-skid pad 17 abuts against the suitcase blank to prevent the suitcase blank from moving during the cutting process.

[0023] The connecting rod 20 is slidably connected to the sleeve 21. At least one longitudinally arranged slide groove 27 is provided on the side of the connecting rod 20. The upper end of the sleeve 21 is blocked. At least one block 28 is provided on the inner wall of the sleeve 21. The block 28 is arranged corresponding to the slide groove 27. The block 28 moves up and down in the slide groove 27. A connecting plate 22 is distributed on the side of the sleeve 21, and a cutting assembly 8 is provided on the connecting plate 22.

[0024] The cutting assembly 8 includes an annular cutter 24 and a fixed plate 23. The blade of the annular cutter 24 is set downward. The annular cutter 24 is sleeved on the lower mold 11. The annular cutter 24 moves downward to cut the edge scraps of the suitcase blank. Four fixed plates 23 are distributed on the upper end surface of the annular cutter 24. The end of the connecting plate 22 is connected to the inner wall surface of the fixed plate 23. Two adjacent fixed plates 23 are vertically arranged. The fixed plate 23 is correspondingly arranged to the through groove 18, and the fixed plate 23 passes through the through groove 18.

[0025] The outer surface of the fixing plate 23 is provided with a limiting block 26 , which is arranged corresponding to the limiting groove 19 . The limiting block 26 slides up and down in the corresponding limiting groove 19 to prevent the annular cutter 24 from being displaced during the cutting process.

[0026] A pressure ring 25 is provided on the side of the annular cutter 24, and the pressure ring 25 is arranged in cooperation with the blade 13. The pressure ring 25 presses down so that the blade 13 cuts the scraps into pieces to facilitate falling. Mounting holes are distributed on the pressure ring 25, and each air nozzle 9 is facing the collection box 3. The air nozzle 9 is connected to an external air pump. The air nozzle 9 blows air towards the scrap fragments to make the plastic fragments fall and prevent the plastic fragments from being stuck between the blades 13.

[0027] The suitcase blank shaping device described in the embodiment is used to place the plastic case blank on the lower mold 11, start the hydraulic cylinder 7, and the piston of the hydraulic cylinder 7 moves downward. The hydraulic cylinder 7 drives the roller upper mold 5 and the cutting assembly 8 to move downward. The upper mold 5 is pressed on the plastic case blank, and the anti-skid pad 17 abuts on the top of the suitcase blank to prevent the suitcase blank from moving during the cutting process. After the upper mold 5 is fixed, the cutting assembly 8 continues to move downward, and the annular cutter 24 moves downward to cut the edge scraps of the suitcase blank. After the scraps are separated from the suitcase shell, the annular cutter 24 continues to move downward, and the pressure ring 25 is pressed downward so that the blade 13 cuts the scraps. After the scraps are chopped, the PLC controls the air pump to deliver high-pressure airflow to the air nozzle 9. The high-pressure airflow causes the plastic fragments to fall and prevents the plastic fragments from being stuck between the blades 13. Then the hydraulic cylinder 7 retracts and drives the cutting assembly 8 to move upward. Then the limit block 26 and the upper edge of the limit groove 19 are released and drive the upper mold 5 to move upward, so that the worker can remove the suitcase shell. After a certain amount of plastic fragments are stored in the collection box 3, the box door 4 is opened, and the handle 16 is pulled to drive the end of the collecting plate 14 to lift up, so that the crushed scraps of the suitcase slide down to one end of the box door 4. The plastic fragments are collected in a transfer container for easy recycling and saving production costs.
