Description

Technical Field

[0001] This utility model relates to the field of thermoforming parts cutting technology, specifically a cutting component for dividing thermoforming equipment. Background Technology

[0002] The vacuum forming process involves heating and softening a plastic sheet, which is then adhered to a mold to form a specific three-dimensional shape. At this point, a cutting component is needed to precisely cut and separate the formed unit from the scraps of the sheet, thereby obtaining an independent vacuum-formed product.

[0003] Existing patent application number: CN213441120U A blister sheet cutting machine includes a frame, a conveyor line, a cutting mechanism, a pressing mechanism, and a material collection mechanism; the setting of guide rods and guide sleeves will allow the slide to slide only along the guide rods, and the opening of the cutter guide groove will allow the cutter to slide only along the groove wall of the cutter guide groove.

[0004] The aforementioned patent describes a cutting component in the vacuum forming process. In practical applications, after the plastic sheet is heated and vacuum-formed, wrinkles easily form at its edges. Without pressure and reinforcement measures, the cutting head is prone to deviating from the cutting contour, affecting processing accuracy. Therefore, we propose a cutting component for dividing vacuum forming equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting component for slitting in a vacuum forming equipment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cutting assembly for slitting in a thermoforming device, comprising a base, a support column, a top frame, a hydraulic cylinder, a piston rod, and a pressing and cutting mechanism. The base has symmetrically erected support columns on its top left and right sides. A top frame is mounted on the top of each support column. A hydraulic cylinder is erected in the center of the top surface of the top frame. A piston rod is telescopically mounted at the bottom of the hydraulic cylinder. A pressing and cutting mechanism is mounted at the bottom end of the piston rod. The pressing and cutting mechanism includes a blade holder, a sliding sleeve, a spring, a ring, a blade holder assembly, a blade head, and a locking mechanism. The blade holder is slidably mounted on the bottom surface of the piston rod. Sliding sleeves are mounted and connected to the left and right sides of the blade holder. The sliding sleeves are slidably mounted on the surface of the support column. A spring is mounted on the lower part of the piston rod surface. A ring is embedded and fixed in the center of the piston rod surface. The upper and lower ends of the spring are respectively connected to the ring and the blade holder. The bottom end of the piston rod is connected to the blade holder assembly. The left and right ends of the blade holder assembly are bolted to the blade head. The blade head is located in the bottom cavity of the blade holder. A locking mechanism is provided on the surface of the sliding sleeve.

[0007] Preferably, when the spring is in its free length state, the cutter head is completely retracted into the bottom cavity of the cutter holder.

[0008] Preferably, the tool holder assembly includes a hollow tube sleeve, a telescopic frame, a gear, and a rack. The hollow tube sleeve is fitted and fixed to the bottom end of the piston rod. The telescopic frame is symmetrically and slidably arranged at both ends inside the hollow tube sleeve. The end of the telescopic frame is bolted to the tool head. A gear is rotatably assembled in the middle of the inner side of the hollow tube sleeve. A rack is installed at the front end of the telescopic frame, and the rack meshes with the teeth on the surface of the gear.

[0009] Preferably, the telescopic travel range of the telescopic frame and the hollow tube sleeve is not less than 50mm.

[0010] Preferably, the locking mechanism includes a first locking hole, a second locking hole, and a limiting pin. The first locking hole is formed through both sides of the surface of the support column, and the second locking hole is formed through both sides of the surface of the sliding sleeve. The inner diameter of the second locking hole is the same as that of the first locking hole, and the limiting pin connects the second locking hole and the first locking hole together.

[0011] Preferably, there are no fewer than three lock holes, wherein the lock holes are equidistantly arranged along the column surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a pressing and cutting mechanism at the bottom of the piston rod. By placing the plastic sheet in the working area of ​​the machine base and then activating the hydraulic cylinder, the cutter holder contacts and presses the plastic sheet before the cutter head. The piston rod then drives the cutter head to continue moving downwards until the cutter head cuts and separates the forming unit from the scrap of the sheet, thereby obtaining an independent thermoformed product. The cutter holder provides pressing and reinforcement to the cutter head, preventing it from deviating from the cutting contour.

[0013] This utility model features a tool holder assembly at the bottom of the piston rod. The telescopic brackets at both ends of the hollow tube sleeve can be extended and retracted. The synchronous extension and retraction of the telescopic brackets at both ends is maintained through the cooperation of gears and racks to prevent the center of gravity from shifting. This allows the tool holder assembly to be installed and adapted to tool heads of different sizes and specifications, thus improving its applicability.

[0014] This utility model features a locking mechanism on the surface of the sliding sleeve. By using a limiting pin to connect the second locking hole with the first locking hole, the sliding sleeve and the support are locked in position. Then, the hydraulic cylinder is activated to drive the pressing and cutting mechanism to move downward, so that the piston rod directly drives the blade holder assembly and the blade head to move downward away from the bottom cavity of the blade holder, making it convenient for workers to replace the blade head.

Detailed Implementation

[0017] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0018] Please see Figure 1 This utility model provides a cutting component for slitting in a thermoforming equipment, including a base 1, a support column 2, a top frame 3, a hydraulic cylinder 4, a piston rod 5, and a pressing and cutting mechanism 6. The support column 2 is symmetrically erected on the left and right sides of the top of the base 1. The top frame 3 is mounted on the top of the support column 2. The hydraulic cylinder 4 is erected in the middle of the top surface of the top frame 3. The piston rod 5 is telescopically mounted at the bottom of the hydraulic cylinder 4. The pressing and cutting mechanism 6 is mounted at the bottom of the piston rod 5.

[0019] Please see Figure 2 This utility model provides a cutting component for slitting in a thermoforming device. The pressing and cutting mechanism 6 includes a blade holder 61, a sliding sleeve 62, a spring 63, a ring 64, a blade holder assembly 65, a blade head 66, and a locking mechanism 67. The blade holder 61 is slidably sleeved on the bottom surface of the piston rod 5. The sliding sleeve 62 is mounted and connected on the left and right sides of the blade holder 61. The sliding sleeve 62 is slidably sleeved on the surface of the support column 2. The spring 63 is sleeved on the lower part of the surface of the piston rod 5. The ring 64 is embedded and fixed in the middle of the surface of the piston rod 5. The upper and lower ends of the spring 63 are respectively installed and connected to the ring 64 and the blade holder 61. The bottom end of the piston rod 5 is installed and connected to the blade holder assembly 65. The left and right ends of the blade holder assembly 65 are bolted to the blade head 66. The blade head 66 is located in the bottom cavity of the blade holder 61. The sliding sleeve 62 is provided with a locking mechanism 67.

[0020] To further explain, when the spring 63 is in its free length state, the cutter head 66 is completely retracted into the bottom cavity of the cutter holder 61, preventing the cutter head 66 from being exposed and causing safety hazards when not in operation.

[0021] Specifically, by setting a pressing and cutting mechanism 6 at the bottom of the piston rod 5, the plastic sheet is first placed in the working area of ​​the machine base 1, and then the hydraulic cylinder 4 is started. At this time, the hydraulic cylinder 4 drives the pressing and cutting mechanism 6 to move down through the piston rod 5. During this process, the cutter holder 61 will contact and press the plastic sheet before the cutter head 66. Then the piston rod 5 drives the cutter head 66 to continue to move down until the cutter head 66 cuts and separates the forming unit from the scrap of the sheet, thereby obtaining an independent thermoformed product. The cutter holder 61 can provide the cutting head 66 with pressing and reinforcement of the plastic sheet to prevent it from deviating from the cutting contour. After the cutting operation is completed, the hydraulic cylinder 4 drives the pressing and cutting mechanism 6 to move upward through the piston rod 5. During this process, the spring 63 releases its elastic force to push the blade holder 61 downward, so that the blade holder 61 covers the surface of the blade head 66, preventing the blade head 66 from being exposed and causing safety hazards when not in operation.

[0022] Please see Figure 3-4 This utility model provides a cutting component for slitting in a thermoforming device. The blade assembly 65 includes a hollow tube sleeve 651, a telescopic frame 652, a gear 653, and a rack 654. The hollow tube sleeve 651 is fixedly mounted on the bottom end of the piston rod 5. The telescopic frame 652 is symmetrically and slidably arranged at both ends inside the hollow tube sleeve 651. The end of the telescopic frame 652 is bolted to the blade head 66. The gear 653 is rotatably mounted in the middle of the inner side of the hollow tube sleeve 651. The rack 654 is installed at the head end of the telescopic frame 652. The rack 654 and the gear 653 mesh with each other.

[0023] To further explain, the telescopic frame 652 and the hollow tube sleeve 651 have a telescopic stroke range of no less than 50mm to provide sufficient adjustment distance to accommodate the assembly of cutter heads 66 of different sizes and specifications.

[0024] Specifically, by setting a tool holder assembly 65 at the bottom of the piston rod 5, the telescopic brackets 652 at both ends of the hollow tube sleeve 651 can be telescopically adjusted, and the telescopic brackets 652 at both ends are kept telescopically extended and retracted synchronously by the cooperation of gear 653 and rack 654 to prevent the center of gravity from shifting, so that the tool holder assembly 65 can be installed and adapted to tool heads 66 of different sizes and specifications, thus improving applicability.

[0025] Please see Figure 5 This utility model provides a cutting component for dividing a thermoforming device. The locking mechanism 67 includes a first locking hole 671, a second locking hole 672, and a limiting pin 673. The first locking hole 671 is opened through both sides of the surface of the support column 2, and the second locking hole 672 is opened through both sides of the surface of the sliding sleeve 62. The inner diameter of the second locking hole 672 is the same as that of the first locking hole 671. The limiting pin 673 connects and inserts the second locking hole 672 and the first locking hole 671 together, thereby locking the position of the sliding sleeve 62 and the support column 2.

[0026] To further explain, there are no fewer than three locking holes 671. The locking holes 671 are equidistantly arranged along the surface of the support column 2, providing different locking positions for the sliding sleeve 62. This makes it easier for workers to lock the sliding sleeve 62 at a suitable height position, so as to better carry out the subsequent replacement of the cutter head 66.

[0027] Specifically, by setting a locking mechanism 67 on the surface of the sliding sleeve 62, when replacing the cutter head 66, the limit pin 673 is used to connect and insert the second locking hole 672 and the first locking hole 671 together to lock the position of the sliding sleeve 62 and the support column 2. Then, the hydraulic cylinder 4 is activated to drive the pressing and cutting mechanism 6 to move down. Since the cutter holder 61 is restricted to the current height by the sliding sleeve 62, the piston rod 5 will directly drive the cutter holder assembly 65 and the cutter head 66 to move down away from the bottom cavity of the cutter holder 61, making it convenient for workers to replace the cutter head 66.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
