Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl chloride production, in particular to a high-performance calender for the production of polyvinyl chloride products. Background Art

[0002] During the production process of polyvinyl chloride film, a calender is usually used to calender the raw material mixture extruded from an extruder or an open mill to press it into a polyvinyl chloride film that meets the required specifications and dimensions.

[0003] At present, the existing PVC film calender lacks the function of trimming the PVC film, resulting in the PVC film needing to be transferred for trimming after calendering, which greatly reduces the production efficiency of the PVC film. In this regard, we propose a high-performance calender for the production of PVC products to solve the above-mentioned problems. Utility Model Content

The two guide blocks 14 are slidably connected in the slide groove 13. The sliding cooperation between the guide block 14 and the slide groove 13 can prevent the moving rod 10 from rotating with the bidirectional screw rod 9 when the screw rod 9 rotates, thereby achieving a guiding and positioning effect.

[0022] A fixing seat 15 is fixedly welded on the top wall of one end of the portal frame 8, and a stud 16 is threadedly connected to the fixing seat 15. A locking block 17 is rotatably installed on the bottom end of the stud 16. A locking wheel 18 is fixedly installed on the bidirectional screw rod 9, and the locking block 17 is pressed onto the locking wheel 18. Through the cooperation of the set stud 16, the locking block 17 and the locking wheel 18, the bidirectional screw rod 9 can be locked after the two trimming tools 11 are adjusted to ensure the stability of the trimming tool 11 during the trimming process.

[0023] A blowing box 19 is fixedly mounted on the inner wall of each of the two fixing rods 6 , and a plurality of evenly distributed blowing nozzles 20 are fixedly mounted on the blowing box 19 .

[0025] Working principle: When the utility model is in use, after the polyvinyl chloride film is calendered by the calendering machine main body 2, it is guided by two guide rollers 7 to the winding roller 3 for winding. During the calendering and winding process of the polyvinyl chloride film, the two trimming tools 11 provided can be used to trim the polyvinyl chloride film, eliminating the subsequent transportation and trimming process, thereby improving the production efficiency of the polyvinyl chloride film. The bidirectional screw rod 9 can be rotated by the hand wheel 12, so that the two moving rods 10 move toward or back to each other on the bidirectional screw rod 9 under the guiding action of the guide block 13, which is convenient for adjusting the spacing between the two trimming tools 11, thereby facilitating the trimming requirements of polyvinyl chloride films of different widths, and has higher applicability. The provided cold air fan 21 can blow low-temperature air into the two auxiliary air ducts 23 respectively through the main air duct 22, and the low-temperature air is blown to the passing polyvinyl chloride film through the blowing box 19 and multiple blowing nozzles 20, which is convenient for cooling the polyvinyl chloride film and facilitating the rapid shaping of the polyvinyl chloride film, thereby facilitating subsequent trimming processing.
