Description

Technical Field

[0001] This utility model relates to the field of PVC board production equipment, and in particular to a longitudinal cutting structure suitable for the production of thin PVC boards. Background Technology

[0002] PVC sheets come in various thicknesses, from thick (e.g., 10 mm) to thin (e.g., 5 mm). During production, PVC sheets need to be trimmed or divided into different sizes. Cutting thick PVC sheets requires more power, while cutting thin PVC sheets requires less power. Using a thick cutting blade would result in waste and increased production costs. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a cost-saving longitudinal cutting structure suitable for the production of thin PVC sheets.

[0004] This utility model is achieved through the following technical solution: A longitudinal cutting structure suitable for the production of thin PVC sheets includes two bases that can move on a frame, a rotating cylinder with a shaft between the two bases, a rotating device for the rotating cylinder, a shaft-rotating screw at each end of the rotating cylinder, a slider threadedly connected to the shaft-rotating screw after it extends into the rotating cylinder, an elongated hole on the rotating cylinder, and a longitudinal cutting blade device fixedly mounted on the slider after it extends out of the elongated hole.

[0005] The longitudinal cutting device includes a blade cylinder, a screw shaft is rotatably mounted on the blade cylinder, a sliding blade holder is provided inside the blade cylinder, and the screw shaft is threadedly connected to the sliding blade holder; the sliding blade holder is provided with a cutting blade.

[0006] The lead screw, longitudinal cutting device, and rotating device are each equipped with a hand crank.

[0007] The rotating device includes: a worm gear mounted on a base, and a matching worm wheel on the worm screw.

[0008] The rotating cylinder is equipped with scale lines.

[0009] The beneficial effects of this utility model are: This invention features three hand cranks: one controls the height of the cutting blade, one controls the movement of the cutting blade to the appropriate position, and one controls the rotation of the cutting blade to the appropriate position. Through the cooperation of these three hand cranks, this invention enables the cutting of thin PVC sheets in a convenient and quick manner. Furthermore, no external power is required during operation, resulting in low cost. Attached Figure Description

[0013] The attached figure shows a specific embodiment of this utility model.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figures 1 to 6 As shown, this longitudinal cutting structure suitable for the production of thin PVC sheets includes two bases 1, which are respectively installed on both sides of the frame of the production line. A rotating cylinder 2 is installed between the two bases 1. The rotating cylinder 2 is rotatable, and its rotation is achieved by a rotating device, specifically: A worm gear with a rotating shaft is installed on one of the bases 1, and a worm wheel is installed on the rotating cylinder 2. The worm wheel is matched with the worm gear 3. The rotating cylinder 2 is driven to rotate through the cooperation of the worm wheel and the worm gear 3. A hand crank 4 is installed at the end of the worm gear.

[0017] A lead screw 5 is installed on each base 1, and a hand crank 4 is also installed on the outer end of the lead screw 5. After the lead screw 5 extends into the inside of the rotating cylinder 2, a slider 6 is threadedly connected. An elongated hole is opened on the rotating cylinder 2. It can be a long elongated hole or two short elongated holes. After the slider 6 extends out of the elongated hole, a longitudinal cutting device is fixedly installed.

[0018] The longitudinal cutting device includes a cutter cylinder 7 fixed to the slider 6. The length of the cutter cylinder 7 is perpendicular to the length of the rotating cylinder 2. A rotating screw 8 is installed at one end of the cutter cylinder 7, and a hand crank 4 is also installed at the outer end of the screw 8. There is a sliding cutter holder 9 inside the cutter cylinder 7. The sliding cutter holder 9 can only move along the axial direction of the cutter cylinder 7. Specifically, the cutter cylinder 7 and the sliding cutter holder 9 can be connected by splines and spline grooves, or the inner cavity of the cutter cylinder 7 can be non-circular, i.e. elliptical, polygonal, etc. The above structures are all existing technologies and will not be described in detail.

[0019] A cutting blade 10 is mounted on the outer end of the sliding blade holder 9. The cutting blade 10 is movable and replaceable. The structure can be as follows: like Figure 4 and Figure 5 As shown, several threaded blade posts 11, which can also be understood as bolts, are installed on the outer end of the sliding blade holder 9. The cutting blade 10 is placed on the sliding blade holder 8, and then a fixing plate 12 is used to fix the cutting blade 10 with nuts 13.

[0020] To facilitate adjustment between the two cutting blades 10, scale lines are engraved on the rotating cylinder 2.

[0021] In use, adjust the distance between the two cutting blades 10 according to the required width of the PVC board using the hand crank 4; then rotate the rotating cylinder 2 using another hand crank 4 so that the cutting blades 10 face the PVC board; and then adjust the height of the cutting blades 10 using the third hand crank 4 to cut the PVC board.
