Description

Technical Field

[0001] This utility model relates to the field of PP sheet processing technology, specifically to a PP sheet edge cutting device. Background Technology

[0002] PP sheets refer to sheet-like raw materials made of polypropylene. During the processing of PP sheets, edge trimming is required. Edge trimming removes burrs, flash, and other uneven parts from the edges of the sheet, thereby improving the surface quality and appearance of the product, making it smoother and neater.

[0003] Existing PP sheet trimming devices require manual cleaning of the waste material after trimming, which causes some inconvenience for operators. Utility Model Content

[0004] The purpose of this invention is to provide a PP sheet cutting device.

[0005] The technical problem solved by this utility model is that the existing PP sheet cutting device requires manual cleaning of the waste material after cutting during use, which brings certain inconvenience to the staff.

[0006] This utility model can be achieved through the following technical solution: a PP sheet cutting device, including a worktable, on which two cutting mechanisms are symmetrically slidably connected. Each cutting mechanism includes a support plate that is horizontally slidably connected to the bottom wall of the sliding groove of the worktable. A fixed frame is fixedly installed on the outer side of the support plate, and a hydraulic cylinder is fixedly installed on the top wall of the fixed frame. A cutter that is vertically slidably connected to the inner cavity of the fixed frame is fixedly installed at the output end of the hydraulic cylinder. By using two hydraulic cylinders to drive the two cutters respectively, the flexibility of the equipment can be improved, thereby meeting the needs of workers. A waste collection groove is opened on the top wall of the support plate. A guide inclined plate is fixedly installed on the inner side wall of the waste collection groove of the support plate. A collection drawer that works with the guide inclined plate is slidably connected to the inner bottom wall of the waste collection groove of the support plate. After a certain amount of waste is collected in the collection drawer, the waste stored in the inner cavity can be cleaned by sliding the collection drawer.

[0007] A further technical improvement of this utility model is that the height of the support plate is flush with the height of the workbench, which makes it easier for the support plate to better support the PP sheet material.

[0008] A further technical improvement of this utility model is that a PP sheet clamping mechanism is provided on the back of the workbench. The PP sheet clamping mechanism includes a support frame fixed to the middle of the back of the workbench. A threaded rod is threadedly connected to the top wall of the support frame. A sliding plate is vertically slidably connected to the inner side wall of the support frame. The bottom end of the threaded rod is rotatably connected to the sliding plate. A main clamping member is provided on the side of the sliding plate away from the threaded rod. Rotating the threaded rod causes the sliding plate to slide vertically on the inner side wall of the support frame.

[0009] A further technical improvement of this utility model is that: the inner cavity of the fixing frame is also vertically slidably connected with an auxiliary clamping component that works in conjunction with the main clamping component. The cooperation between the main clamping component and the auxiliary clamping component facilitates the stable clamping of PP sheet material.

[0010] A further technical improvement of this utility model is that: the main clamping member or the auxiliary clamping member includes a clamping plate, and a rubber plate is vertically and elastically slidably connected to the inner cavity of the clamping plate.

[0011] A further technical improvement of this utility model is that the auxiliary clamping member and the main clamping member are connected by a telescopic member. The telescopic member includes an outer sleeve fixed to the clamping plate in the main clamping member, and the inner cavity of the outer sleeve is horizontally elastically slidably connected to an inner sleeve fixed to the clamping plate in the auxiliary clamping member.

[0012] A further technical improvement of this utility model is that a connecting rod assembly is fixedly installed on one side of the bearing plate, and a sliding groove assembly for the connecting rod assembly to slide is provided on the top wall of the workbench.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model places PP sheet material on a workbench and adjusts its position relative to the workbench. After adjustment, the PP sheet material is clamped and fixed. When clamping and fixing it, the threaded rod is rotated to move the main clamping member toward the PP sheet material. Since the main clamping member is fixed to the auxiliary clamping member through the telescopic member, the auxiliary clamping member moves synchronously while the main clamping member moves, which facilitates the stable clamping of the PP sheet material to be cut. After it is clamped and fixed, two hydraulic cylinders are driven at the same time to make the cutter cut the PP sheet material. The waste material after cutting is automatically put into the collection drawer after being guided by the guide plate, so that it does not need to be cleaned by hand, thus meeting the needs of workers.

[0015] 2. This utility model utilizes the rotation of a bidirectional screw to drive the relative movement of two screw sleeves, which in turn drive the synchronous movement of the bearing plate fixed to them. The bearing plate causes the connecting rod assembly to slide within the inner cavity of the slide groove assembly. The relative movement of the two bearing plates causes the auxiliary clamping component to move synchronously. The movement of the auxiliary clamping component facilitates the subsequent fixing of the PP sheet to be trimmed, thus enabling the equipment to stably clamp the PP sheet according to its size specifications before trimming, thereby facilitating the subsequent trimming work and making it convenient to use.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figure 1-6 As shown, this embodiment provides a technical solution: a PP sheet cutting device, including a workbench 1. A PP sheet clamping mechanism is provided on the back of the workbench 1. The PP sheet clamping mechanism includes a support frame 3 fixed to the middle of the back of the workbench 1. A sliding plate 31 is vertically slidably connected to the inner side wall of the support frame 3. A threaded rod 32 is threadedly connected to the top wall of the support frame 3. The bottom end of the threaded rod 32 is rotatably connected to the sliding plate 31 through a bearing. A main clamping member 33 is provided on the side of the sliding plate 31 away from the threaded rod 32.

[0031] Two sliding grooves are symmetrically opened on both sides of the workbench 1. A cutting mechanism 2 is slidably installed on the inner bottom wall of the sliding groove of the workbench 1. The cutting mechanism 2 includes a support plate 21 that is horizontally slidably connected to the inner bottom wall of the sliding groove of the workbench 1. The height of the support plate 21 is flush with the height of the workbench 1. A fixing frame 22 is fixedly installed on the outer side of the support plate 21. A hydraulic cylinder 23 is fixedly installed on the top wall of the fixing frame 22. A cutter 24 that is vertically slidably connected to the inner cavity of the fixing frame 22 is fixedly installed at the output end of the hydraulic cylinder 23. A waste collection groove is opened on the top wall of the support plate 21. A guide inclined plate 25 is fixedly installed on the inner side wall of the waste collection groove of the support plate 21. A collection drawer 26 that cooperates with the guide inclined plate 25 is slidably connected to the inner bottom wall of the waste collection groove of the support plate 21.

[0032] The inner cavity of the fixing frame 22 is also vertically slidably connected to an auxiliary clamping member 34. Both the main clamping member 33 and the auxiliary clamping member 34 include a clamping plate 37. The inner cavity of the clamping plate 37 is vertically elastically slidably connected to a rubber plate 38, which abuts against the top wall of the PP sheet.

[0033] Each main clamping member 33 and each auxiliary clamping member 34 are connected by a telescopic member 35. The telescopic member 35 includes an outer sleeve 351 fixed to the clamping plate 37 in the main clamping member 33. A compression spring 353 is fixedly installed on the inner wall of the outer sleeve 351. An inner sleeve 352 fixed to the compression spring 353 is horizontally slidably connected to the inner cavity of the outer sleeve 351. The side of the inner sleeve 352 away from the outer sleeve 351 is fixed to the connecting plate 36 at the top of the clamping plate 37 in the auxiliary clamping member 34. The telescopic member 35 enables the equipment to simultaneously adjust the distance between the two auxiliary clamping members 34 when adjusting the distance between the two cutters 24, thereby facilitating the equipment to better clamp and fix the PP sheet material to be cut.

[0034] A connecting rod assembly 4 is fixedly installed on one side of the bearing plate 21. A sliding groove assembly 41 for sliding the connecting rod assembly 4 is provided on the top wall of the workbench 1. The cooperation between the connecting rod assembly 4 and the sliding groove assembly 41 can prevent the PP sheet from shifting significantly during edge cutting due to the opening of the sliding groove, thus facilitating the use by workers.

[0035] A drive mechanism for moving two support plates 21 relative to each other is provided at the middle of the bottom wall of the workbench 1. The drive mechanism includes a housing 5 fixed to the middle of the bottom wall of the workbench 1. A bidirectional screw 51 is rotatably connected to the inner cavity of the housing 5. Two external threads with opposite directions are provided on the side of the bidirectional screw 51 near the end. Each of the two external threads with opposite directions is threaded with a sleeve 52 that is horizontally slidably connected to the inner cavity of the housing 5. The sleeve 52 is fixedly connected to the support plate 21.

[0036] A servo motor 53 that drives the bidirectional screw 51 to rotate is fixedly installed on one side of the housing 5.

[0037] In use, the distance between the two bearing plates 21 is first adjusted according to the PP sheet material to be cut. During adjustment, the bidirectional screw 51 is driven to rotate by the servo motor 53. Since the external threads on the outer surface of the bidirectional screw 51 are two segments with opposite threads, the rotation of the bidirectional screw 51 can drive the two screw sleeves 52 to move relative to each other. Then, the two screw sleeves 52 drive the bearing plate 21 fixed to them to move synchronously. The connecting rod assembly 4 slides in the inner cavity of the slide groove assembly 41 through the bearing plate 21.

[0038] The relative movement of the two bearing plates 21 causes the auxiliary clamping member 34 to move synchronously. The movement of the auxiliary clamping member 34 facilitates the subsequent fixation of the PP sheet to be cut. At this time, the PP sheet is placed on the worktable 1, and the position of the PP sheet is adjusted relative to each other. After adjustment, the PP sheet is clamped and fixed. When clamping and fixing it, the threaded rod 32 is rotated to make the main clamping member 33 move toward the PP sheet. Since the main clamping member 33 is fixed to the auxiliary clamping member 34 through the telescopic member 35, the movement of the main clamping member 33 drives the auxiliary clamping member 34 to move synchronously, which facilitates the stable clamping of the PP sheet to be cut. After it is clamped and fixed, the two hydraulic cylinders 23 are driven at the same time. The hydraulic cylinders 23 cause the cutter 24 to cut the PP sheet. The waste material after cutting is automatically put into the collection drawer 26 after being guided by the guide plate 25, so that it does not need to be cleaned by hand, thus meeting the needs of workers.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
