Description

Technical Field

[0001] This invention belongs to the field of air conditioner hollow panel processing technology, specifically a cutting device for preparing air conditioner hollow panels. Background Technology

[0002] Air conditioner hollow panels are a type of sheet material with a hollow structure, commonly used in certain components of air conditioners. These panels are primarily made from environmentally friendly, pollution-free, and recyclable thermoplastic materials, such as polypropylene (PP) and polyethylene (HDPE), through a special process. During processing, the dimensions of the produced hollow panels may not perfectly match the installation requirements of the air conditioner components. Therefore, edge trimming is necessary to adjust the dimensions and achieve precise specifications. This edge trimming process removes excess edges and corners from the air conditioner. Typically, an automatic die-cutting machine performs rapid cutting of the panels. The hollow panels are placed on a conveyor table, their position is determined by a positioning device, and then conveyed to the die-cutting module by a conveyor. The hollow panels are then die-cut using cutting tools and clamps.

[0003] However, existing automatic die-cutting machines typically use steel blades to cut air conditioner hollow panels. Since air conditioner hollow panels are made of polypropylene (PP), some material tends to adhere to the surface of the steel blade during the cutting process. This can cause localized deformation of the die-cut material, resulting in a rough cut and hindering subsequent installation and use. This can lead to substandard quality air conditioner hollow panels. Furthermore, existing die-cutting machines are not convenient for cleaning debris, which remains on the worktable and affects subsequent die-cutting.

[0004] Therefore, a cutting device for preparing air conditioning hollow panels is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0009] Preferably, a drive rod is fixedly connected to the center of the drive disk, and a motor is fixedly connected to the end of the drive rod away from the drive disk.

[0010] Preferably, the lifting assembly includes a cam, which is fixedly connected to the side of the drive disk away from the grinding plate. The cam rotates coaxially with the drive disk, and a limit component is provided at the top of the worktable directly below the cam.

[0011] Preferably, the limiting component includes multiple limiting wheels, which contact the edge of the cam. Each of the multiple limiting wheels is fixedly connected to a support rod, and the bottom of the support rod is fixedly connected to a support block. The bottom of the support block is fixedly connected to the worktable.

[0012] Preferably, the vertical plate is provided with a buffer assembly, the buffer assembly includes a movable plate, the movable plate is rotatably connected to a drive rod, the vertical plate has a movable groove inside, the movable plate slides inside the movable groove, and a buffer spring is fixedly connected inside the movable groove, the buffer spring is fixedly connected to the bottom of the movable plate.

[0013] Preferably, a collection box is placed on top of the workbench, and the collection box is snapped into the center of the vertical plate and the cutting table.

[0014] Preferably, the clamping assembly includes two clamping plates, each clamping plate has an electric push rod fixedly connected to its top, the electric push rod has an mounting plate fixedly connected to its top, the mounting plate has a fixed plate hinged to it, the fixed plate has a support plate fixedly connected to its bottom, the support plate is on the same side as the clamping plates and slides along the cutting table, the support plate has a slider fixedly connected to its bottom, and the slider is slidably connected to a groove.

[0015] Preferably, the pushing mechanism includes a pushing plate, which is trapezoidal in shape. A driving block is engaged with one of the inclined sides of the pushing plate. The side of the driving block that contacts the pushing plate is also inclined. The pushing plate is triangular in shape. An electric telescopic rod is fixedly connected to the bottom of the driving block. The bottom of the electric telescopic rod is fixedly connected to the worktable. A through slot is provided at the position below the driving block on the cutting table. The driving block moves along the through slot. A return spring is fixedly connected to the side of the pushing plate near the horizontal plate. The return spring is fixedly connected to the horizontal plate. Connecting rods are fixedly connected to both symmetrical sides of the pushing plate. The two connecting rods are respectively fixedly connected to two fixed plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention facilitates rapid grinding of the cut edges of cut materials by incorporating a grinding plate, a translation component, and a lifting component. A pushing mechanism moves the material body and clamping components synchronously towards the grinding plate. The translation and lifting components work together to move the grinding plate along the cut edge of the material, achieving rapid grinding. This solves the problem of uneven cut edges caused by existing edge-cutting devices using steel blades, which hinders rapid grinding and reduces the accuracy of material cutting, thus lowering product quality.

[0017] This invention facilitates the reciprocating lifting and lowering of the entire grinding plate by using a combination of a cam, a limiting component, a moving plate, and a buffer spring. The cam rotates synchronously via a drive disc. During rotation, the cam contacts the bottom limiting wheel. Since the limiting wheel's position is relatively fixed, when the cam's protruding end rotates to the bottom, it moves the entire cam upwards, causing the drive disc and grinding plate to rise synchronously. When the cam's flat end rotates to the bottom, the cam descends. During this process, the moving plate rises and falls within the moving groove. Simultaneously, the bottom buffer spring provides a buffering effect, preventing wear caused by the gravity of the cam, drive disc, and grinding plate during lifting and lowering.

[0018] This invention facilitates the rapid pushing of the cut sheet material by setting up a clamping assembly, a pushing plate, a driving block, and a collection box, thereby simplifying the collection of cutting and grinding impurities. The sheet material is placed on a support plate, and the mounting plate is rotated to be perpendicular to the support plate. An electric push rod then moves the clamping plate downwards to clamp and fix the sheet material. After cutting, an electric telescopic rod moves the driving block downwards, which then contacts and limits the pushing plate. The pushing plate, pushed by a return spring, presses against the sheet material and the fixing plate, causing the fixing plate to slide along the groove. Simultaneously, the cut sheet material moves synchronously towards the grinding plate for surface grinding. The grinding dust falls into the bottom collection box for collection. Furthermore, when the pushing mechanism is used again, cutting impurities are also pushed out of the cutting table and fall into the collection box, thus completing the cutting, grinding, and collection of the entire air conditioning unit's hollow core panel.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As shown, this invention provides a cutting device for preparing air conditioning hollow panels, including a workbench 1. A vertical plate 11 is fixedly connected to the top of the workbench 1, a top plate 12 is fixedly connected to the top of the workbench 1, and a cutting table 13 is fixedly connected to the top of the workbench 1. The cutting table 13 is inverted T-shaped, and a horizontal plate 131 is fixedly connected to the side of the cutting table 13 away from the vertical plate 11. Sliding grooves 132 are symmetrically provided on both sides of the top of the cutting table 13. A cutting blade 2 is provided directly above the cutting table 13, and an electric cylinder 21 is fixedly connected to the top of the cutting blade 2. The top of the electric cylinder 21 is fixedly connected to the top plate 12. A sheet body 3 is placed on the cutting table 13, and the cutting table 13 is equipped with... There is a clamping assembly 14 for fixing the plate body 3. A grinding mechanism 4 for grinding the cutting edge is provided on the vertical plate 11. A collection box 5 is placed on the top of the worktable 1. The collection box 5 is snapped into the center of the vertical plate 11 and the cutting table 13. A pushing mechanism 6 is provided on the side of the cutting table 13 near the horizontal plate 131. The grinding mechanism 4 includes a grinding plate 41. The grinding plate 41 is located on the side of the cutting table 13 near the cutting blade 2. The grinding plate 41 is T-shaped. Slide rods 411 are fixedly connected to both sides of the center of the grinding plate 41. A translation assembly 42 and a lifting assembly 43 for driving the grinding plate 41 to move and lift are provided on the side of the grinding plate 41 near the vertical plate 11.

[0023] Using the above solution: When in use, the plate body 3 to be cut is placed on the top of the cutting table 13. The plate is clamped and fixed by the clamping component 14. After fixing, the cutting blade 2 is moved down by the electric cylinder 21 to cut the edge of the plate body 3. In order to avoid the plate interface being uneven after cutting, the plate body 3 and the clamping component 14 are moved synchronously towards the grinding plate 41 by the pushing mechanism 6. The grinding plate 41 is moved up, down and left and right along the cut of the plate by the translation component 42 and the lifting component 43, thereby achieving a rapid grinding effect. The grinding dust falls into the bottom collection box 5 for collection. At the same time, when the pushing mechanism 6 is used to push, the cutting impurities can also be pushed out of the cutting table 13 and fall into the collection box 5 at the same time. Thus, the cutting, grinding and collection of the entire air conditioning hollow plate is completed.

[0024] like Figure 5 As shown, the translation component 42 includes a drive disk 421. A crank 422 is fixedly connected to the center of the drive disk 421 near the grinding plate 41. A sliding seat 423 is slidably disposed at the end of the crank 422 away from the drive disk 421. The sliding seat 423 is fixedly connected to the protruding end of the grinding plate 41. A connecting plate 4211 is fixedly connected to the symmetrical sides of the drive disk 421. A limit sleeve 4212 is fixedly connected to the side of the connecting plate 4211 near the drive disk 421. The slide rod 411 slides along the inside of the limit sleeve 4212. A drive rod 424 is fixedly connected to the center of the drive disk 421. A motor 425 is fixedly connected to the end of the drive rod 424 away from the drive disk 421.

[0025] The above solution is adopted: by using motor 425 to drive drive rod 424 to rotate, drive rod 424 to drive drive disk 421 to rotate synchronously, and then crank 422 on drive disk 421 to rotate synchronously. During the rotation, crank 422 slides in sliding seat 423, thereby driving sliding seat 423 to move along slide rod 411 in limiting sleeve 4212, and then driving the entire grinding plate 41 to move, so as to achieve horizontal grinding of the cutting part of plate body 3.

[0026] like Figure 4As shown, the lifting assembly 43 includes a cam 431, which is fixedly connected to the side of the drive disk 421 away from the grinding plate 41. The cam 431 and the drive disk 421 rotate coaxially. A limit component 432 is provided at the top of the worktable 1, directly below the cam 431. The limit component 432 includes multiple limit wheels 4321, which contact the edge of the cam 431. Each of the multiple limit wheels 4321 is fixedly connected to a support rod 4322. A support block 4323 is fixedly connected to the bottom, and the bottom of the support block 4323 is fixedly connected to the workbench 1. A buffer assembly 44 is provided inside the vertical plate 11. The buffer assembly 44 includes a movable plate 441, which is rotatably connected to the drive rod 424. A movable groove 111 is provided inside the vertical plate 11, and the movable plate 441 slides inside the movable groove 111. A buffer spring 442 is fixedly connected inside the movable groove 111, and the buffer spring 442 is fixedly connected to the bottom of the movable plate 441.

[0027] The above scheme is adopted: by using the rotation of the drive disk 421 to drive the cam 431 to rotate synchronously, during the rotation of the cam 431, it contacts the bottom limit wheel 4321. Since the position of the limit wheel 4321 is relatively fixed, when the protruding end of the cam 431 rotates to the bottom, it can drive the entire cam 431 to move upward, thereby driving the drive disk 421 and the grinding plate 41 to rise synchronously. When the cam 431 rotates smoothly to the bottom, the cam 431 descends. During this process, the moving plate 441 rises and falls inside the moving groove 111. At the same time, the bottom buffer spring 442 plays a certain buffering role to avoid wear caused by the gravity process of the entire cam 431, drive disk 421 and grinding plate 41 during the lifting and lowering process.

[0028] like Figure 10As shown, the clamping assembly 14 includes two clamping plates 141. An electric push rod 143 is fixedly connected to the top of each clamping plate 141. A mounting plate 144 is fixedly connected to the top of each electric push rod 143. A fixing plate 145 is hinged to the mounting plate 144. A support plate 142 is fixedly connected to the bottom of the fixing plate 145. The support plate 142 is on the same side as the clamping plates 141 and slides along the cutting table 13. A slider 1451 is fixedly connected to the bottom of the support plate 142. The slider 1451 is slidably connected to the slide groove 132. The pushing mechanism 6 includes a pushing plate 61, which is trapezoidal in shape. A drive mechanism is engaged on one inclined side of the pushing plate 61. Block 62, the side of the drive block 62 that contacts the push plate 61 is inclined, the push plate 61 is triangular, the bottom of the drive block 62 is fixedly connected to an electric telescopic rod 63, the bottom of the electric telescopic rod 63 is fixedly connected to the worktable 1, the cutting table 13 is located below the drive block 62 and has a through groove 133, the drive block 62 moves along the through groove 133, the side of the push plate 61 near the horizontal plate 131 is fixedly connected to a return spring 64, the return spring 64 is fixedly connected to the horizontal plate 131, the symmetrical sides of the push plate 61 are fixedly connected to connecting rods 65, the two connecting rods 65 are fixedly connected to two fixed plates 145 respectively.

[0029] The above solution involves placing the sheet material on the support plate 142 and rotating the mounting plate 144 to make it perpendicular to the support plate 142. At this time, the electric push rod 143 drives the clamping plate 141 to move down and clamp the sheet material body 3. After cutting, the electric telescopic rod 63 drives the drive block 62 to move down, thereby limiting the contact part of the push plate 61. The push plate 61, under the push of the return spring 64, squeezes the sheet material body 3 and the fixing plate 145, thereby driving the fixing plate 145 to slide along the slide groove 132. At the same time, the cut sheet material moves synchronously and approaches the grinding plate 41 to grind its surface. After grinding, the drive block 62 is moved upward to squeeze the inclined side of the push plate 61 to limit it, which is convenient for subsequent use.

[0030] The working principle and usage process of this invention are as follows: When using this device, the plate body 3 to be cut is placed on the top of the cutting table 13, and the plate is clamped and fixed by the clamping assembly 14. After fixing, the cutting blade 2 is driven down by the electric cylinder 21 to cut the edge of the plate body 3. After cutting, the driving block 62 is driven down by the electric telescopic rod 63, which then contacts the limiting part of the push plate 61. The push plate 61 is pushed by the return spring 64 to press the plate body 3 and the fixing plate 145, thereby driving the fixing plate 145 to slide along the slide groove 132. At the same time, the cut plate moves synchronously and approaches the grinding plate 41. The driving rod 424 is driven to rotate by the motor 425. The rotation of the driving rod 424 drives the driving disk 421 to rotate synchronously, thereby causing the crank 422 on the driving disk 421 to rotate synchronously. During the rotation, the crank 422 slides in the sliding seat 423, thereby driving the sliding seat 423 to move along the slide rod 41. 1. The plate moves horizontally within the limiting sleeve 4212, thereby driving the entire grinding plate 41 to move horizontally, achieving horizontal grinding of the cut area of ​​the plate body 3. Simultaneously, the drive disc 421 rotates, causing the cam 431 to rotate synchronously. During the rotation of the cam 431, it contacts the bottom limiting wheel 4321. Since the position of the limiting wheel 4321 is relatively fixed, when the protruding end of the cam 431 rotates to the bottom, it can drive the entire cam 431 to move upward, thereby driving the drive disc 421 and the grinding plate 41 to rise synchronously. When the cam 431 rotates smoothly to the bottom, the cam 431 descends. During this process, the moving plate 441 rises and falls inside the moving groove 111, and at the same time, it works with the bottom buffer spring 442 to provide a certain buffering effect. The grinding dust falls into the bottom collection box 5 for collection. At the same time, when the pushing mechanism 6 is used to push, the cutting impurities can also be pushed out of the cutting table 13 and fall into the collection box 5 synchronously, thus completing the cutting, grinding and collection of the entire air conditioning hollow plate.
