DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0027] See also Figure 1-3 As shown, the utility model is a film removal machine for recycling plastic bottles, comprising a cutting and separation box 1 and a negative pressure film collection box 2 that are connected. The cutting and separation box 1 is fixed through the upper end of the negative pressure film collection box 2. A belt conveyor assembly 3 for bidirectional conveying is installed inside the cutting and separation box 1. A cutting assembly 4 is installed on one side wall of the cutting and separation box 1, and the conveying direction of the belt conveyor assembly 3 and the cutting direction of the cutting assembly 4 are downward. A conical funnel 14 is fixed to the upper end of the cutting and separation box 1. A rectangular through hole 11 that cooperates with the cutting assembly 4 is opened on the side wall of the cutting and separation box 1. The cutting assembly 4 includes a driving motor 41 and a motor mounting seat 42. The motor mounting seat 42 is fixed to the outer wall of the cutting and separation box 1. A row of cutting blades 43 are installed on the output shaft of the driving motor 41 along its axial direction. The distance between the cutting and separation box 1 and the belt conveyor assembly 3 only allows plastic bottles to flow vertically downward.
[0028] The side wall of the cutting and separating box 1 is provided with a discharge port 12. The discharge port 12 is located directly below the rectangular through hole 11. A row of S-shaped guide round rods 13 are fixed to the inner wall of the cutting and separating box 1 opposite to the discharge port 12 and the lower end of the discharge port 12.
[0029] The belt conveyor assembly 3 specifically includes an electric drive roller 31, a first reversing roller 32, a second reversing roller 33, and a belt 34 wound around the electric drive roller 31, the first reversing roller 32, and the second reversing roller 33. The axis of the first reversing roller 32 and the axis of the second reversing roller 33 are on the same vertical plane. The axis of the first reversing roller 32 is located above the rectangular through hole 11. The axis of the second reversing roller 33 is located below the rectangular through hole 11. The electric drive roller 31 is located at the upper end of the cutting and separation box 1, and the electric drive roller 31 is away from the inner wall of the rectangular through hole 11 of the cutting and separation box 1. A row of cutting blades 43 partially passes through the rectangular through hole 11 and faces the belt 34 between the first reversing roller 32 and the second reversing roller 33.
[0030] The recycled plastic bottles flow from the conical funnel 14 into the cutting and separation box 1, and the belt conveyor assembly 3 drives the plastic bottles downward. When the plastic bottles are conveyed between the first reversing roller 32 and the second reversing roller 33, a row of cutting blades 43 drives the plastic bottles downward again. A row of cutting blades 43 cuts the label film on the surface of the plastic bottle into multiple sections, and then quickly throws it downward. Under the action of air resistance, the label film is quickly separated from the bottle body. The plastic bottle body turns along the S-shaped guide rod 13 and then is discharged from the discharge port 12.
[0031] The negative pressure film collecting box 2 is a rectangular box structure. A sealed box door 21 is provided on one wall of the negative pressure film collecting box 2. The cutting and separation box 1 is placed on the right side of the upper end of the negative pressure film collecting box 2. An inclined mesh partition 22 is provided on the left corner inside the cutting and separation box 1. A filter sponge 23 is installed in the space above the mesh partition 22. An air outlet pipe 24 is fixed through the upper end surface of the negative pressure film collecting box 2, and the air outlet pipe 24 is located directly above the filter sponge 23. A rectangular groove 25 connected to the air outlet pipe 24 is provided on the upper end surface of the filter sponge 23. The air outlet pipe 24 is connected to an exhaust device to exhaust the internal air pressure of the negative pressure film collecting box 2 to a negative pressure. This embodiment uses a centrifugal fan 5 to exhaust air. The air inlet of the centrifugal fan 5 is connected to the air outlet pipe 24.
[0032] The negative pressure film collecting box 2 is in a negative pressure state, and the label film separated at the S-shaped guide rod 13 is sucked into the negative pressure film collecting box 2. Under the joint action of the mesh partition 22 and the filter sponge 23, the label film is retained in the negative pressure film collecting box 2. When cleaning is needed, the sealed box door 21 can be opened to clean the accumulated label film.
[0033] In order to reduce the airflow entering from the discharge port 12, a row of flip doors are installed on the side wall of the cutting and separation box 1 above the discharge port 12 through hinges.
