Description

Technical Field

[0001] This utility model relates to the field of plastic sheet cutting technology, and in particular to a protective mechanism and its cutting machine. Background Technology

[0002] Plastic sheets need to be cut during production. Currently, plastic sheets are cut by cutting multiple stacked plastic sheets using a cutting machine.

[0003] Application No. 202321548740.X discloses a cutting device for plastic products, including a cutting table. Fixed frames are fixedly connected to both ends of the cutting table's center. Baffles are fixedly connected to both ends of the right side of the top of the cutting table. Conveyor belts are installed on both the front and rear sides of the left side of the cutting table. An electric push rod is installed at the top of the chute, and sliders are fixedly connected to both the left and right sides of the bottom of the electric push rod. A cutting blade is fixedly connected to the output end of the electric push rod. In this cutting device, the spring at the bottom of the cutting blade is pushed upwards by the plastic product, exposing the internal cutting blade to cut the plastic product. After the cutting blade completes cutting from right to left, the spring returns the cutting blade to its original position, protecting the cutting blade and effectively preventing damage. However, due to the adhesiveness of some plastic products, some waste material adheres to the surface of the blade after cutting the plastic sheet. Long-term accumulation can easily affect the cutting performance of the blade on the plastic sheet. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] This utility model provides, for example Figure 1-4 The protective mechanism shown includes: a body 1, a blade 2 on the top of the body 1 for pressing and cutting plastic products, and a support mechanism 3 on the top of the body 1. The support mechanism 3 includes: a support frame 31, a slide 32 and a movable groove 33. The support frame 31 has an inverted U-shaped structure and is fixed to the top of the body 1. The slide 32 is opened on the top of the support frame 31 and is an inverted T-shaped groove. The movable groove 33 is opened at the bottom of the slide 32 to facilitate communication between the movable groove 33 and the inner cavity of the slide 32.

[0039] It also includes: a drive mechanism 4 and a cleaning mechanism 5. The drive mechanism 4 is mounted on the support mechanism 3. The drive mechanism 4 is used for vertical telescopic cutting of the blade 2. The drive mechanism 4 is set in the inner cavity of the slide 32. The drive mechanism 4 includes: a hydraulic cylinder 41, a fixing plate 42 and a positioning block 43. The hydraulic cylinder 41 is set above the support frame 31. The fixing plate 42 slides on the top of the support frame 31. Locking parts are provided on both sides of the fixing plate 42. The locking parts are used to limit the position of the fixing plate 42 on the support frame 31. The hydraulic cylinder 41 is fixed to the surface of the fixing plate 42. The positioning block 43 is fixed to the bottom of the fixing plate 42. The positioning block 43 has an inverted T-shaped structure that cooperates with the slide 32. The positioning block 43 is slidably inserted into the inner cavity of the slide 32. The telescopic end of the hydraulic cylinder 41 is slidably inserted into the middle of the positioning block 43.

[0040] Furthermore, the cleaning mechanism 5 is installed at the bottom of the drive mechanism 4. The cleaning mechanism 5 is used for scraping and cleaning the two sides of the blade 2. The cleaning mechanism 5 is also used for bottom protection of the blade 2. The telescopic end of the hydraulic cylinder 41 is connected to the cleaning mechanism 5. The cleaning mechanism 5 includes: a moving frame 51, a limiting rod 52, a compression spring 53, and a protective component 54. The moving frame 51 is installed at the bottom telescopic end of the hydraulic cylinder 41. Driven by the hydraulic cylinder 41, the moving frame 51 can move stably above the machine body 1. The blade 2 is fixed to the bottom of the moving frame 51 by screws, so that the blade 2 can stably cut the plastic sheet above the machine body 1. The limiting rod 52 is fixed in the inner cavity of the moving frame 51. The compression spring 53 is sleeved on the outside of the limiting rod 52. The compression spring 53 is installed between the protective component 54 and the moving frame 51. Through the elasticity of the compression spring 53, the protective component 54 can move in the inner cavity of the moving frame 51.

[0041] Specifically, the protective component 54 is used for protecting the outer wall of the blade 2 and preventing scraping of the outer wall of the blade 2. The protective component 54 includes: a protective plate 541, two inner arc edges 542, and two chamfered edges 543. The top of the protective plate 541 is slidably inserted into the inner cavity of the moving frame 51. The bottom of the compression spring 53 is fixed to the top of the protective plate 541, and the top of the compression spring 53 is fixed to the top of the inner wall of the moving frame 51. The limiting rod 52 is slidably inserted into the top of the protective plate 541. Through the elasticity of the compression spring 53, when the blade 2 is not cutting, the protective plate 541 can provide safety protection for the bottom of the blade 2, reducing the injury caused by accidental contact with the blade 2. The inner arc edges 542 are formed at the protective plate 541. The inner wall of the protective plate 541 has a chamfered edge 543 at its end. The chamfered edge 543 is slidably connected to the outer wall of the blade 2, which facilitates the chamfered edge 543 to push out the waste material on the outer wall of the blade 2. When cutting is required, the hydraulic cylinder 41 drives the blade 2 to press. At this time, through the compression performance of the compression spring 53, the bottom of the protective plate 541 presses the two sides of the cutting plate, improving the stability when cutting plastic sheets. At the same time, after cutting, the protective plate 541 attached to the outer wall of the blade 2 can scrape the outer wall of the cut blade 2, so that most of the waste material on the blade 2 can be hung off the outer wall of the blade 2, improving the cleaning performance of the outer wall of the blade 2.

[0042] Furthermore, an electric telescopic rod 6 is fixedly connected to the side of the support frame 31, and a sorting plate 7 is fixedly connected to one end of the electric telescopic rod 6. The sorting plate 7 is slidably connected to the inner cavity of the machine body 1, which facilitates the sorting plate 7 to sort the plastic sheet on the machine body 1 and improve the cutting efficiency.

[0043] like Figure 1 As shown, this embodiment provides a cutting machine, which includes the aforementioned protective mechanism.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
