[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] This utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this utility model.

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural diagram of an embodiment of a positionable plastic sheet cutting device, including:

[0034] Please see Figures 1-5 This utility model provides a technical solution:

[0035] A positionable plastic sheet cutting device includes a base 1, a fixed seat 3 bolted to the top of the base 1, a hydraulic cylinder 31 bolted to the top of the fixed seat 3, a guide rod 32 sleeved at the bottom of the hydraulic cylinder 31, a slide block 33 bolted to one end of the guide rod 32, a groove 34 formed inside the slide block 33, a slide rod 35 bolted to the inner wall of the groove 34, a motor 37 bolted to one end of the slide block 33, a lead screw 36 inserted into the output shaft of the motor 37, a slider 38 sleeved on the outer circumference of the lead screw 36, and a motor 39 bolted to the bottom of the slider 38. The output shaft is inserted into the cutting disc 310. A vertical groove 313 is provided on one side of the fixed base 3. A vertical rod 312 is connected to the inner wall of the vertical groove 313 by bolts. A vertical block 311 is sleeved on the outer circumference of the vertical rod 312. One end of the vertical block 311 is connected to the slide block 33 by bolts. While the guide rod 32 is driven by the hydraulic cylinder 31 to move the slide block 33 up and down, the slider 38 is driven by the motor 37 to move back and forth in the horizontal direction. This makes it easy for the motor 39 to drive the cutting disc 310 to rotate back and forth to cut the plastic sheet, thereby achieving the purpose of complete cutting. This is convenient for various non-cutting solutions and improves the overall practicality of the device.

[0036] The hydraulic cylinder 31 operates by transmitting pressure from hydraulic oil within a sealed cavity to achieve mechanical motion. When the hydraulic pump pumps oil into one end of the cylinder, the resulting pressure pushes the piston to the other end, thereby extending or retracting the piston rod; when oil is supplied in the opposite direction, the piston moves in the opposite direction. By controlling the flow and pressure of the oil, precise linear reciprocating motion or force output can be achieved. The magnitude of the power depends on the product of the oil pressure and the effective area of ​​the piston. This is existing technology, and in this text, it is referred to as hydraulic cylinder 31 and guide rod 32.

[0037] Among them, the driving method of motor 37 and motor 39 is full-voltage direct drive. The specific principle is that the rated voltage is directly applied to the stator winding of motor 37 through the contactor, so that it can obtain the maximum torque instantaneously from the stationary state. Therefore, motor 37 and motor 39 can be controlled separately.

[0038] It is worth noting that, in order to fix the whole device, specifically, the top of the base 1 is connected by bolts to multiple symmetrically distributed support legs 6, and the top of the support legs 6 is connected by bolts to the top plate 2. The structural design of multiple symmetrically distributed support legs 6 facilitates the fixation of the whole device.

[0039] Next, in order to improve the capacity efficiency of a single recycling, the top plate 2 has a groove 51 on its top. The inner wall of the groove 51 is bolted to a collection box 5. The inner wall of the collection box 5 has a slot 52. The inner wall of the slot 52 is slidably connected to a drawer 53. One end of the drawer 53 is bolted to a handle 54. The inner wall of the collection box 5 is bolted to a crushing roller 511. Through the structural design of the crushing roller 511, the waste put into the collection box 5 is crushed into fine particles, thereby effectively reducing the space occupied by the waste and improving the capacity efficiency of a single recycling.

[0040] Meanwhile, to reduce the impact of residue on subsequent material cutting, specifically, the inner wall of the collection box 5 is bolted with a recess 510, the inner wall of the recess 510 is connected with a mounting plate 59 via a damping bearing, one end of the mounting plate 59 is bolted with a pneumatic actuator 57, the top of the pneumatic actuator 57 is bolted with a mounting block 56, both sides of the mounting block 56 are connected with a protruding plate 512 via damping bearings, and the top of the protruding plate 512 is bolted with a cover plate 55. By driving the pneumatic actuator 57, the damping bearing is adjusted under the action of the pneumatic actuator 57, allowing the cover plate 55 to change its angle. This facilitates the dumping of residue generated on the top of the cover plate 55 during the cutting process into the drawer 53, thereby reducing the impact of residue on subsequent material cutting.

[0041] Among them, the pneumatic actuator 57 is a linear motion device driven by compressed air, which is widely used in automation equipment, robotic arms, and conveying systems. Its working principle is based on pneumatic transmission, and the core is to convert the energy of compressed air into mechanical linear motion. This is existing technology, and is referred to as pneumatic actuator 57 in this article.

[0042] Furthermore, to facilitate the clamping of plastic sheets of various thicknesses by the horizontal block 42, specifically, a horizontal groove 4 is provided on the top of the top plate 2, and a horizontal bar 41 is connected to the inner wall of the horizontal groove 4 by bolts. The horizontal block 42 is sleeved on the outer circumference of the horizontal bar 41, and a spring 44 is welded to the bottom of the inner wall of the horizontal block 42. A pressure plate 45 is on the top of the spring 44. Through the cooperation of the spring 44 and the pressure plate 45, and the design of the handle 47 connected by the nut 48, it is convenient for the horizontal block 42 to clamp plastic sheets of various thicknesses.

[0043] Finally, in order to fix plastic sheets of various sizes, specifically, a handle 47 is sleeved on the top of the horizontal block 42, a nut 48 is threaded on the outer circumference of the handle 47, a clamp 46 is fixed at the bottom of the handle 47, and a fixing ring 43 is provided at one end of the horizontal block 42. The fixing ring 43 is threadedly connected to the horizontal bar 41. Through the structural design of the fixing ring 43, it is easy to fix the horizontal block 42 at any position on the inner wall of the horizontal groove 4, thereby facilitating the fixing of plastic sheets of various sizes.

[0044] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0045] The device or equipment models mentioned in this article may be as follows:

[0046] Motor: Y802-4.

[0047] Combination Figures 1-5 The specific usage process of the positionable plastic sheet cutting device of this embodiment is as follows:

[0048] 1: When using this positioning plastic sheet cutting device, the operator moves the base 1 to a suitable position, places the plastic sheet to be cut on the top of the top plate 2, and rotates the fixing ring 43, thereby pushing the horizontal block 42 to move horizontally on the outer circumference of the horizontal bar 41 and the inner wall of the horizontal groove 4. After moving to a suitable position, the horizontal bar 41 is fixed by the threaded connection of the fixing ring 43. At this time, the nut 48 is rotated, and the handle 47 is pulled to drive the clamping plate 46 to extend upward, so that the plastic sheet to be cut can be fixed on the top of the pressure plate 45 and the spring 44. Then, the handle 47 is pressed down, so that the clamping plate 46 fits the plastic sheet, and the nut 48 is rotated to fix it.

[0049] 2: When the device needs to cut plastic sheets, the operator drives the guide rod 32 to lift the slide block 33 by means of the hydraulic cylinder 31 connected to the top of the fixed seat 3 by bolts. At the same time, the motor 37 drives the lead screw 36 to rotate, so that the slider 38 moves back and forth in the horizontal direction on the inner wall of the slide groove 34. This makes it easier for the motor 39 to drive the cutting disc 310 to rotate back and forth to cut the plastic sheet, thereby achieving the purpose of complete cutting. This makes it suitable for various non-cutting needs and improves the overall practicality of the device.

[0050] 3: When the device needs to collect waste, the operator can drive the pneumatic actuator 57, so that the cover plate 55 can change its angle under the dual action of the damping bearing and the pneumatic actuator 57. This makes it easier to pour the residue generated on the top of the cover plate 55 during the cutting process into the collection box 5. Then, by using the handle 54 to drive the drawer 53 to slide and connect the slot 52, the residue can be taken out for centralized cleaning, thereby reducing the impact of residue on subsequent material cutting.

[0051] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
