Description

Technical Field

[0001] This utility model relates to the technical field of sheet material trimming equipment, and in particular to a PVC sheet material trimming device. Background Technology

[0002] In the PVC sheet processing industry, edge trimming is a crucial process to ensure the dimensional accuracy of the sheets and their compatibility with subsequent assembly. With the increasing demands for surface quality in industries such as building decoration and furniture manufacturing, traditional edge trimming equipment is gradually becoming insufficient to meet production needs.

[0003] In existing technologies, such as the PVC sheet trimming device disclosed in Chinese Utility Model Patent Publication No. CN222609708U, although dust collection during the trimming process is achieved through structures such as protective covers, cutting blades, and dust collection components, which improves the working environment to some extent, and the flexibility of trimming operation is improved by adjusting the position of the trimming head with a drive mechanism, this type of equipment still has significant technical defects in practical applications: PVC sheet material has a certain degree of toughness, and after being trimmed by a saw blade, its sidewalls are prone to burrs, rough edges, or micro-cracks due to cutting stress. These defects not only affect the flatness of the sheet appearance, but may also lead to problems such as poor sealing and misalignment during subsequent splicing and installation, and may even affect the performance of surrounding components due to burrs falling off during use.

[0004] However, most current edge trimming equipment only has a single edge trimming function. If burr removal is required on the trimmed boards, the boards must be transferred to specialized grinding equipment for secondary processing. This step-by-step operation mode of edge trimming, transfer, and grinding increases process flow time and labor costs, reducing overall production efficiency. Furthermore, the boards are prone to collisions and displacement during transfer, which may damage the dimensional accuracy of the trimmed edges, further affecting product quality stability.

[0005] In addition, some equipment that attempts to integrate edge trimming and grinding functions often adopts a fixed structure design, and the relative positions of the grinding component and the edge trimming component are not adjustable. This not only makes it difficult to flexibly switch the operation mode according to the thickness of the board and the material characteristics, but also requires the disassembly of a large number of related structures when the saw blade or grinding component is worn and needs to be replaced. This makes the operation cumbersome, the maintenance inconvenient, and seriously restricts the continuous operation capability of the equipment.

[0006] Based on the aforementioned industry pain points, there is an urgent need to develop a PVC sheet trimming device that can quickly switch between trimming and sanding functions and whose easily damaged parts are easy to replace, in order to shorten the processing flow, improve product quality stability, and meet the needs of modern PVC sheet processing for high efficiency and integration. Utility Model Content

[0007] To address the aforementioned issues, this invention provides a PVC sheet trimming device that enables rapid switching between trimming and sanding modes.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a PVC sheet trimming device, comprising a housing, both ends of which are open, and further comprising:

[0009] The saw blade and the grinding wheel are detachably and rotatably mounted at both ends of the housing, and both the saw blade and the grinding wheel are fixed to the housing by fasteners;

[0010] Two driven gears are provided and are coaxial with the saw blade and the grinding wheel respectively, and the two driven gears are detachably connected to the saw blade and the grinding wheel respectively;

[0011] A drive gear is located inside the housing and is laterally slidably connected to one side of the housing. One end of the drive gear is connected to a drive motor via a mounting base.

[0012] A drive housing is located on the outer wall of the housing. The mounting base is slidably installed inside the drive housing. The drive housing is provided with a drive component for the mounting base to slide laterally, so that the sliding of the mounting base drives the drive gear to approach the driven gear.

[0013] By adopting the above technical solution, it is possible to quickly adjust the manual grinding process after manual cutting.

[0014] Furthermore, a cylinder with an inner cross groove is fixedly installed on one side surface of the driven gear, and a cross-shaped insert is fixedly installed on one side surface of both the saw blade and the grinding wheel, with the cross-shaped insert and the cylinder being interlocked.

[0015] By adopting the above technical solution, it is possible to quickly install saw blades and grinding wheels.

[0016] Furthermore, a cross-shaped insert is rotatably mounted on one side surface of the saw blade and the grinding wheel. The fastener is a fastening screw, and a cross bar is fixedly mounted on one end of the fastening screw. Threaded holes are symmetrically opened on one side surface of the housing. One end of the fastening screw is screwed into the threaded hole, and the cross bar and the cross-shaped insert are interlocked.

[0017] By adopting the above technical solution, the saw blade and the grinding wheel can be quickly fixed.

[0018] Furthermore, both the cross-shaped insert and the cross rod are made of rubber, specifically hard rubber, and the cross-shaped insert and the cross rod are respectively interference-fitted with the cylinder and the cross-shaped insert cylinder.

[0019] By adopting the above technical solution, the connection strength between the cross rod and the cylinder and the cross tube can be enhanced.

[0020] Furthermore, a sliding groove is provided on one side surface of the housing, and the drive gear is connected to the mounting base via a sliding shaft. A ball bearing is sleeved on the sliding shaft, and the ball bearing is slidably engaged in the sliding groove.

[0021] By adopting the above technical solution, the drive gear can be limited.

[0022] Furthermore, mounting plates are fixedly installed at the four corners of the outer wall of the drive housing, and the mounting plates are fixedly connected to the housing by mounting screws.

[0023] By adopting the above technical solution, the drive housing can be installed.

[0024] Furthermore, the driving component includes a ball screw, which is slidably connected to the mounting base. One end of the ball screw is rotatably connected to the inner wall of the housing, and a transverse motor is fixedly mounted on the other end of the ball screw. The transverse motor is fixedly connected to the outer wall of one end of the driving housing.

[0025] By adopting the above technical solution, the mounting base can be limited and slid within the drive housing by the rotation of the ball screw.

[0026] Furthermore, both the top and bottom of the housing are made of transparent material.

[0027] By adopting the above technical solution, it is easier for staff to observe the meshing of the drive gear and the driven gear.

[0028] In summary, this utility model has the following beneficial effects: This device allows users to first trim the edges of PVC sheets with a saw blade, and then drive the drive gear to move closer to the driven gear on the side of the grinding wheel through the drive component. Then, through the meshing of the drive gear and the driven gear, the grinding wheel starts to work, thereby realizing the multi-functional use of trimming and grinding. Moreover, this device is highly convenient, and both the saw blade and the grinding wheel are easy to replace. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] like Figure 1-6 As shown in the figure, this application discloses a PVC sheet trimming device, including a housing 1, with openings at both ends, and further comprising:

[0038] The saw blade 2 and the grinding wheel 13 are detachably and rotatably mounted at both ends of the housing 1. Both the saw blade 2 and the grinding wheel 13 are fixed to the housing 1 by fasteners 3.

[0039] Two driven gears 4 are provided and are coaxial with the saw blade 2 and the grinding wheel 13 respectively, and the two driven gears 4 are detachably connected to the saw blade 2 and the grinding wheel 13 respectively;

[0040] The drive gear 5 is located inside the housing 1 and is laterally slidably connected to one side of the housing 1. One end of the drive gear 5 is connected to the drive motor 15 through the mounting base 14.

[0041] The drive housing 6 is located on the outer wall of the housing 1. The mounting base 14 is slidably installed inside the drive housing 6. The drive housing 6 is provided with a drive component 7 for the mounting base 14 to slide laterally, so that the drive gear 5 will move closer to the driven gear 4 through the sliding of the mounting base 14. It should be noted that the structure of the mobile power supply and controller used in this device is not described, because they are existing technologies that are mature and used in the market, so this device does not describe them.

[0042] Example 2: A cylinder 8 with an internal cross groove is fixedly installed on one side surface of the driven gear 4. A cross-shaped insert 9 is fixedly installed on one side surface of both the saw blade 2 and the grinding wheel 13. The cross-shaped insert 9 is interlocked with the cylinder 8. A cross-shaped sleeve 16 is rotatably installed on one side surface of the saw blade 2 and the grinding wheel 13. The fastener 3 is a fastening screw 301, with a cross-shaped rod 302 fixedly installed at one end. Threaded holes are symmetrically opened on one side surface of the housing 1. One end of the fastening screw 301 is screwed into the threaded hole, and the cross-shaped rod 302 is interlocked with the cross-shaped sleeve 16. Both the cross-shaped insert 9 and the cross-shaped rod 302 are made of rubber, and they are interference-fitted with the cylinder 8 and the cross-shaped sleeve 16, respectively. It should be noted that... To facilitate the installation of the saw blade 2 and the grinding wheel 13, the driven gear 4 is rotatably mounted on one side of the housing 1 via a bearing, and the cylinder 8 is fixedly mounted on the driven gear 4 by welding. When installing the saw blade 2 or the grinding wheel 13, the operator aligns the saw blade 2 with the cross bar 9 and the grinding wheel 13 with the cylinder 8 with the inner cross groove to complete the initial positioning of the saw blade 2. Then, the operator screws the fastening screw 301 into the threaded hole. At this time, the operator needs to rotate the saw blade 2 or the grinding wheel 13 so that the cross bar 302 aligns with the cross bar cylinder 16, and then gradually tightens it to complete the installation of the fastener 3. Since the cross bar 302 and the slot in the cross bar cylinder 16 are interference fit, the stability of the connection can be improved.

[0043] Example 3: In order to adjust the position of the drive gear 5 to switch between trimming and grinding states;

[0044] A groove is formed on one side surface of the housing 1. The drive gear 5 is connected to the mounting base 14 via a sliding shaft 10. A ball bearing 11 is fitted onto the sliding shaft 10 and is slidably engaged in the groove. Mounting plates 12 are fixedly installed at the four corners of the outer wall of the drive housing 6. The mounting plates 12 are fixedly connected to the housing 1 via mounting screws. The drive component 7 includes a ball screw 701, which is slidably connected to the mounting base 14. One end of the ball screw 701 is rotatably connected to the inner wall of the housing 1, and the other end of the ball screw 701 is fixedly mounted with a transverse motor 702. The transverse motor 702 is fixedly connected to one end of the outer wall of the drive housing 6. The top and bottom of the housing 1 are made of transparent material. It should be noted that the ball bearing 11 is rolled and engaged in the groove, while the drive motor 15 is fixedly mounted. Mounted on the mounting base 14, and the mounting base 14 and the inner wall of the drive housing 6 are limited by protrusions and grooves. After the operator installs the drive housing 6, the output end of the drive motor 15 is connected to the sliding shaft 10 through the slot in the mounting base 14. At this time, the drive motor 15 can provide driving force for the rotation of the drive gear 5. After the horizontal motor 702 adjusts the ball screw 701 to rotate, the ball screw 701 drives the mounting base 14 to move, which enables the drive gear 5 to move towards the driven gear 4 on the saw blade 2 or the grinding wheel 13. At this time, the operator can observe the meshing state of the drive gear 5 and the driven gear 4 through the transparent material (select transparent acrylic panel) on the top of the housing 1. The operator can manually rotate the driven gear 4 to make the drive gear 5 and the driven gear 4 mesh.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
