Description

Technical Field

[0001] This utility model relates to the field of plastic sheet cutting, specifically a plastic sheet splicing and cutting equipment. Background Technology

[0002] Plastic sheets refer to materials used in the production of disposable plastic cups, plates, bowls, dishes, boxes and other thermoformed products. They are widely used in packaging for food, vegetables, fruits, beverages, dairy products, industrial parts and other fields or in the production of toys. Depending on the actual needs, cutting equipment is required to cut large pieces of plastic sheets into the specified shapes during the production process.

[0003] According to publicly available patent CN220145035U, a plastic sheet production splicing and cutting equipment includes a base, a worktable fixedly mounted on the top of the base, a laser cutting assembly fixedly mounted on the top of the worktable, two sets of mirror-arranged cabinet doors movably mounted on the front of the base via hinges, a slot opened on the top of the worktable, limit posts fixedly mounted between the inner walls of the two sides of the slot, an adjusting plate rotatably sleeved on the outer surface of the limit posts, an electric push rod fixedly mounted on the bottom wall of the base, and two sets of square plates arranged front and rear fixedly mounted on the bottom of the adjusting plate. In the new design, after the plastic sheet is cut, the debris scattered on the adjusting plate can be easily cleaned up, preventing the bottom of the subsequent plastic sheet from being affected by the protruding debris, which could lead to uneven surfaces and reduced cutting efficiency. Furthermore, the design can limit the plastic sheet's position based on the cut width, improving its stability during the cutting process. Traditionally, the horizontally placed adjusting plate is tilted downwards from back to front to allow residual debris to slide down into the base space. However, this still requires manual cleaning of the debris, which is time-consuming and affects the efficiency of plastic sheet cutting. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1: A plastic sheet splicing and cutting device, see [link to example]. Figures 1 to 3 ,include:

[0034] Processing table 1, the top of which is provided with a cutting component for cutting plastic sheets;

[0035] A dust collection component is installed on the processing table 1 to collect debris generated during the cutting of plastic sheets;

[0036] The dust removal component includes:

[0037] A processing tank 2 is provided on the upper surface of the processing table 1, and a filter plate 21 is horizontally arranged in the inner cavity of the processing tank 2;

[0038] A collection hopper 22 is fixedly connected to the bottom of the processing table 1. The top opening of the collection hopper 22 communicates with the inner cavity of the processing groove 2. A collection box 23 is fixedly connected to the bottom of the processing table 1. The top opening of the collection box 23 communicates with the inner cavity of the collection hopper 22.

[0039] A negative pressure pump 24 is fixedly connected to one side of the collection hopper 22. The suction end of the negative pressure pump 24 is connected to the inner cavity of the collection hopper 22 through a suction pipe 25. A filter screen is provided at the connection between the suction pipe 25 and the collection hopper 22 to prevent debris from entering the negative pressure pump 24 and causing damage.

[0040] During operation, the dust removal components installed on the processing table 1 greatly improve the cutting environment for plastic sheets. Specifically, the filter plate 21 on the processing tank 2 can pass through the debris generated during the cutting process, preventing the debris from scattering everywhere and causing protrusions on the surface of the plastic sheets to be processed later. This ensures that the cut plastic sheets have good surface flatness and significantly improves product quality. The interconnected structure design of the collection hopper 22 and the collection box 23 forms a complete debris collection channel, which can smoothly gather and collect the debris, effectively preventing debris from accumulating in the working area and ensuring stable operation of the equipment.

[0041] Most importantly, the negative pressure pump 24 further enhances the functionality and practicality of this equipment. The negative pressure pump 24 is connected to the inner cavity of the collection hopper 22 through the suction pipe 25. When working, it generates negative pressure, which can not only actively and efficiently suck up debris, but also significantly save cleaning time, improve the cutting efficiency of plastic sheets, and reduce manual cleaning costs compared to the traditional cleaning method that relies on gravity to slide down. At the same time, the negative pressure can also adsorb and limit the plastic sheet on the filter plate 21, so that the plastic sheet remains stable during the cutting process. There is no need for operators to manually limit the plastic sheet, reducing manual intervention and labor intensity, while further improving cutting accuracy and production efficiency, realizing an efficient, clean, and automated plastic sheet cutting production process.

[0042] For details, see Figure 1 The cutting component includes:

[0043] The laser cutting machine 4 has a cutting head 41 at its bottom and also includes a laser generator, an optical fiber transmission system, an optical system, and a control system.

[0044] An adjustment mechanism is located above the processing table 1. The adjustment mechanism is connected to the laser cutting machine 4 for driving the laser cutting machine 4 to move in order to cooperate with the cutting head 41 to cut plastic sheets of different shapes.

[0045] During operation, the laser generator produces a high-energy laser beam, providing a powerful energy foundation for cutting. The fiber optic transmission system ensures stable and efficient transmission of the laser beam to the cutting head 41, reducing energy loss. The optical system precisely focuses the laser beam onto the cutting point, concentrating the laser energy on the plastic sheet. This enables precise cutting within a very small area, effectively avoiding problems such as burrs and deformation that may occur with traditional mechanical cutting. This greatly improves the flatness and smoothness of the cut, ensuring product quality. The adjustment mechanism is connected to the laser cutting machine 4, providing it with flexible movement and adjustment capabilities. By driving the laser cutting machine 4 to move above the processing table 1, the position of the cutting head 41 can be precisely adjusted to closely match the cutting requirements of plastic sheets of different shapes.

[0046] Further, see Figure 1 The adjustment mechanism includes:

[0047] The first adjustment component includes connecting plates 3 symmetrically arranged at both ends of the processing table 1. A first adjustment groove 33 is formed on the surface of the connecting plate 3 along a first direction. A first adjustment block 34 is slidably connected in the first adjustment groove 33. A first lead screw 32 is rotatably connected to the inner cavity of the first adjustment groove 33 through a bearing. The first adjustment block 34 is sleeved on the outside of the first lead screw 32 through an internal thread.

[0048] The second adjustment assembly includes a gantry frame 35 spanning the processing table 1. Both ends of the gantry frame 35 are fixedly connected to the tops of the two first adjustment blocks 34 respectively. The front end of the gantry frame 35 is provided with a second adjustment groove 36 along the second direction. A second adjustment block 38 is slidably connected in the second adjustment groove 36. A second lead screw 37 is rotatably connected to the inner cavity of the second adjustment groove 36 through a bearing. The second adjustment block 38 is sleeved on the outside of the second lead screw 37 through an internal thread.

[0049] The third adjustment component includes a mounting plate 39 fixedly connected to the front end of the second adjustment block 38. The front end of the mounting plate 39 is provided with a third adjustment groove 313 in a third direction. The third adjustment block 311 is slidably connected in the third adjustment groove 313. The laser cutting machine 4 is fixedly connected to the front end of the third adjustment block 311.

[0050] In this design, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane formed by the first and second directions. A three-dimensional adjustment system is constructed through the coordinated design of the first, second, and third adjustment components, enabling the laser cutting machine 4 to perform omnidirectional, high-precision position adjustments in space. Whether performing simple rectangular cutting or complex three-dimensional curved surface cutting tasks, the coordinated movement of each component allows the laser cutting machine 4 to be quickly adjusted to the optimal working position, reducing manual intervention and adjustment time, and significantly improving production efficiency.

[0051] It is worth noting that, see Figure 1 The adjustment mechanism further includes:

[0052] The first drive motor 31 is fixedly installed at one end of one of the connecting plates 3, and the output shaft of the first drive motor 31 is connected to one end of the first lead screw 32 via a coupling.

[0053] The second drive motor 312 is fixedly installed at one end of the gantry frame 35, and the output shaft of the second drive motor 312 is connected to one end of the second lead screw 37 via a coupling.

[0054] An electric telescopic rod 310 is fixedly installed on the top of the mounting plate 39. The telescopic end of the electric telescopic rod 310 is fixedly connected to the top of the third adjusting block 311 and is used to drive the third adjusting block 311 to move along the third direction. Through the first drive motor 31, the second drive motor 312 and the electric telescopic rod 310, the automation level and ease of operation of the equipment are significantly improved, and the overall performance of the plastic sheet splicing and cutting equipment is further enhanced.

[0055] It is worth noting that, see Figure 2 and Figure 3 The bottom two sides of the collection hopper 22 are fixedly connected to connecting blocks 5, which are L-shaped. The top of the collection box 23 is fixedly connected to a fixing frame 51. The width of the fixing frame 51 is adapted to the distance between the inner sides of the two connecting blocks 5. Through the adaptation design of the connecting blocks 5 and the fixing frame 51, a stable and easy-to-operate connection method is formed. When it is necessary to clean or replace the collection box 23, the operator does not need to use additional tools. He can easily separate the collection box 23 from the collection hopper 22 by simply sliding it horizontally to clean the internal debris. Compared with the traditional bolt connection or welding fixation method, this detachable design significantly reduces the maintenance difficulty and time cost, enables the equipment to return to production status more quickly, reduces downtime caused by maintenance, and improves the utilization rate of the equipment and the continuity of production.

[0056] It is worth mentioning that, see Figure 2 and Figure 3 A sealing gasket 52 is fixedly connected to the upper surface of the fixed frame 51. The sealing gasket 52 is integrally molded from elastic rubber material. When the collection box 23 is installed below the collection hopper 22, the sealing gasket 52 is tightly fitted with the lower surface of the connecting block 5 to form a sealing structure. When the collection box 23 is connected to the collection hopper 22, the rubber sealing gasket 52 forms a tight fit with the lower surface of the L-shaped connecting block 5 through its own deformation, effectively filling the connection gap. This sealing structure can prevent air from leaking from the connection when the negative pressure pump 24 is working, ensuring a stable negative pressure environment in the collection hopper 22, and can increase the contact friction between the fixed frame 51 and the L-shaped connecting block 5, thereby improving the stability of the collection box 23 connected to the collection hopper 22.

[0057] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
