AI Technical Summary
During the transport of PVC membrane, dust can easily adhere to the membrane surface, causing bumps, granular spots, or irregular textures after coating. Uneven heating can also lead to excessively rapid cooling, causing the membrane to warp, which increases labor time and costs.
Design a PVC film pretreatment mechanism, including a preheating lamp, a heating fan, a dust collection structure and a heat preservation unit. It removes dust through thermal radiation, hot air heating and dust collection, prevents excessive cooling, and ensures uniform heating and stable conveying of the film material.
It effectively removes dust, prevents surface defects after coating, improves product quality and tightness, reduces secondary heating and repair, lowers labor costs, and improves production efficiency.

Abstract
Claims
1. A PVC film pretreatment mechanism for covering wood strips, characterized in that: The pretreatment box (1) includes openings (101) on both the left and right sides, a preheating lamp (4) located inside the pretreatment box (1) and capable of radiating heat to both sides of the PVC film, and a heating fan (5) located inside the pretreatment box (1) and downstream of the preheating lamp (4). The bottom of the pretreatment box (1) is fixedly connected to a left support column (21) and a right support column (22). A film guiding unit (7) is provided on the side of both the left support column (21) and the right support column (22). A film feeding unit (6) is provided on the outside of the left support column (21), and a heat preservation unit (8) is provided on the right side of the right support column (22). A dust suction structure (3) for suctioning the inner surface of the PVC film is provided below the pretreatment box. The film feeding unit (6) unwinds the PVC film, so that the PVC film passes through the preheating lamp (4), the heating fan (5), the heat preservation unit (8), and the dust suction structure (3) in sequence before entering the wood strip wrapping machine.
2. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 1, wherein: The vacuuming structure (3) includes a vacuum cleaner body (31) fixed to the bottom of the pretreatment box (1), a vacuum cleaner head (32), and a hose (33) connecting the vacuum cleaner body (31) and the vacuum cleaner head (32). The vacuum cleaner head (32) is clamped on the right support column (22).
3. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 2, wherein: The right support column (22) is provided with a vertically extending guide rail (34), a slider (35) slidably connected to the guide rail (34), and a clamping plate (36) that clamps the vacuum head (32) together with the slider (35). The clamping plate (36) is provided with mounting holes (361) at its corners. The slider (35) is provided with threaded holes that are the same number as the mounting holes and correspond one-to-one. A clamping screw (37) is inserted into each mounting hole and the clamping screw (37) is connected to the corresponding threaded hole. A side plate (38) is provided on the side of the slider (35). The side plate (38) is provided with multiple stop screws (39) for pressing towards the right support column (22).
4. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 1, wherein: Two heating fans (5) are provided, which are fixedly connected to the upper and lower ends of the right side of the pretreatment box (1) respectively. The air outlet of each heating fan (5) is fixedly connected to an air expansion pipe (501).
5. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 1, wherein: The film feeding unit (6) includes a fixing frame (601), and a bearing seat (602) is provided on the side of the fixing frame (601). The bearing seat (602) is connected to a film feeding roller (603), and two clamping wheels (604) for clamping PVC film rolls are sleeved on the film feeding roller (603).
6. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 5, wherein: The outer side of each clamping wheel (604) is threaded with a locking bolt (605).
7. A PVC film pre-treatment mechanism for wood strip covering as claimed in claim 1, wherein: The guiding film unit (7) includes a turning support shaft (701) and a guide roller (703) rotatably sleeved on the turning support shaft (701).
8. A PVC film pretreatment mechanism for wood strip wrapping according to claim 1, characterized in that: The heat preservation unit (8) includes a first heat preservation lamp plate (801) and a second heat preservation lamp plate (802). The output ends of the first heat preservation lamp plate (801) and the second heat preservation lamp plate (802) are arranged opposite each other and in an inclined state. The front and rear ends of the first heat preservation lamp plate (801) and the second heat preservation lamp plate (802) are provided with connecting strips (803). The front and rear ends of the first heat preservation lamp plate (801) and the second heat preservation lamp plate (802) are rotatably connected with mounting brackets (804). The mounting brackets (804) are respectively fixedly connected to the front and rear sides of the right side of the pretreatment box (1).
