Description

Technical Field

[0001] The utility model relates to the technical field of shearing equipment, in particular to a shearing machine capable of preventing debris from splashing. Background Art

[0002] Color steel sandwich panel is a composite material composed of color coated steel plate and thermal insulation materials such as polyurethane and rock wool. It has excellent thermal insulation, sound insulation, fire resistance, compression resistance and corrosion resistance, so it is widely used in construction and industrial fields.

[0003] In the prior art, the color steel sandwich panels are cut into suitable sizes with the help of shearing equipment, so as to facilitate the subsequent installation and processing according to the actual situation. At the same time, the uneven and straight edges can be cut off by shearing to ensure the aesthetics and facilitate the subsequent processing. For example, the Chinese utility model patent with the patent publication number of CN212552024U can improve the accuracy of sheet shearing and ensure the advantages of production safety. However, the waste after cutting cannot be removed in time, resulting in manual cleaning by the staff. In addition, since the waste after shearing is far away from the cutting knife, there are certain safety hazards during manual cleaning. In view of this, we propose a shearing machine that can prevent debris from splashing. Utility Model Content

[0007] Preferably, a spring is fixedly connected between the second protective plate and the first protective plate, and a rubber plate is fixedly connected to the lower surface of the second protective plate.

[0008] Preferably, a protective component is also provided on the right side surface of the shearing knife.

[0009] Preferably, a mounting plate is fixedly connected to the upper surface of the workbench, and a limiting plate is slidably connected to the upper surface of the workbench.

[0012] Preferably, an indicating scale is provided on the upper surface of the workbench, and an indicating triangle is fixedly connected to the rear surface of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The shearing machine capable of preventing debris from splashing will synchronously drive the tooth plate to descend during the process of the shearing blade descending. After the tooth plate descends a certain distance, it meshes with the gear and drives the gear to rotate. After the gear rotates, it synchronously drives the drive shaft to rotate. After the drive shaft rotates, it drives the baffle to rotate. After the baffle rotates, it is in a horizontal state to support the color steel sandwich panel extending over the shearing blade. After the shearing is completed, the shearing blade rises and synchronously drives the baffle to rotate in the opposite direction using the gear, so that the sheared waste falls into the interior of the collection box along the inclined baffle. Through the above structure, after shearing, the cut waste can be automatically collected into the interior of the collection box by using the cooperation of gravity and the baffle, avoiding the possibility of danger in manual collection and cleaning, improving the safety of the staff and reducing the difficulty of work.

[0015] (2) The shearing machine capable of preventing debris from splashing can adjust the length of the cut waste material by operating the handle to drive the threaded rod to rotate. Since the limit plate is restricted in its movement trajectory by the workbench, the threaded rod will simultaneously drive the limit plate to move horizontally when it rotates. The indicating triangle plate can also be used in conjunction with the indicating scale to finely adjust the movement distance when the limit plate moves. With the above structure, the length of the color steel sandwich panel that is extended can be quickly determined by adjusting the distance of the limit plate when shearing the color steel sandwich panel, thereby improving the accuracy of shearing.

The tooth plate 10 described in the text is only provided with teeth in the middle part, so that the gear 9 will start to rotate after the tooth plate 10 drops a distance. When the shearing knife 6 contacts the color steel sandwich panel, the gear 9 just rotates ninety degrees. When shearing the color steel sandwich panel, the color steel sandwich panel is placed on the upper surface of the workbench 1, and then the color steel sandwich panel is conveyed to the bottom of the shearing knife 6 by the conveying roller, and then the shearing knife 6 is driven to descend by the hydraulic telescopic rod. After the shearing knife 6 descends, the protective component first contacts the color steel sandwich panel, and the protective component is used to further limit and clamp the color steel sandwich panel. Then the shearing knife 6 continues to descend to complete the shearing of the color steel sandwich panel. During the descent of the shearing knife 6, the tooth plate 10 is synchronously driven to descend, and the tooth plate 10 is meshed with the gear 9 after descending a certain distance. , and drives the gear 9 to rotate. After the gear 9 rotates, it synchronously drives the drive shaft 7 to rotate. After the drive shaft 7 rotates, it drives the baffle 8 to rotate. After the baffle 8 rotates, it is in a horizontal state to support the color steel sandwich panel extending over the shearing knife 6. After the shearing is completed, the shearing knife 6 rises, and the gear 9 is used to drive the baffle 8 to rotate in the opposite direction, so that the sheared waste falls into the collection box 3 along the inclined baffle 8.

The splashing debris generated during shearing will be blocked by the first guard plate 12 and the second guard plate 13. At the same time, when adjusting the length of the cut waste, the threaded rod 18 can be driven to rotate by the control handle 19. Since the movement trajectory of the limit plate 17 is limited by the workbench 1, the limit plate 17 will be synchronously driven to move horizontally when the threaded rod 18 rotates. When the limit plate 17 moves, the indicating triangle plate 21 can also be used to cooperate with the indicating scale 20 to finely adjust the movement distance. Through the above structure, when the color steel sandwich panel is sheared, the length of the color steel sandwich panel extended can be quickly determined by adjusting the distance of the limit plate 17, thereby improving the accuracy of shearing.

[0026] Working principle: When shearing the color steel sandwich panel, the color steel sandwich panel is placed on the upper surface of the workbench 1, and then the conveyor roller is used to convey the color steel sandwich panel to the bottom of the shearing knife 6, and then the hydraulic telescopic rod is used to drive the shearing knife 6 to descend. After the shearing knife 6 descends, the protective component first contacts the color steel sandwich panel, and the protective component is used to further limit and clamp the color steel sandwich panel. Then the shearing knife 6 continues to descend to complete the shearing of the color steel sandwich panel.

After the baffle 8 rotates, it is in a horizontal state to support the color steel sandwich panel extending over the shearing knife 6. After the shearing is completed, the shearing knife 6 rises, and the gear 9 is used to synchronously drive the baffle 8 to reverse. Rotate, so that the sheared waste falls into the interior of the collection box 3 along the inclined baffle 8. When the shear knife 6 descends, the mounting block 11 will be used to drive the first protective plate 12 to descend, and the first protective plate 12 will simultaneously drive the second protective plate 13 and the rubber plate 15 to descend. After the rubber plate 15 descends, it contacts the color steel sandwich panel and then continues to descend so that the second protective plate 13 enters the interior of the first protective plate 12 and compresses the spring 14. The splashing debris generated during shearing will be blocked by the first protective plate 12 and the second protective plate 13. At the same time, when adjusting the length of the cut waste, the threaded rod 18 can be driven to rotate by the operating handle 19. Since the limit plate 17 is limited in its movement trajectory by the workbench 1, the limit plate 17 will be driven to move horizontally when the threaded rod 18 rotates. When the limit plate 17 moves, the indicating triangle 21 can be used in conjunction with the indicating scale 20 to finely adjust the movement distance.
