Description

Technical Field

[0001] This utility model relates to the field of edge trimming technology for thermoformed products, specifically to a forming edge trimming mechanism for thermoformed products. Background Technology

[0002] In the production and processing of thermoformed products, the trimming process is one of the most crucial steps, directly affecting the final quality and appearance of the product. With the continuous growth in market demand for thermoformed products and the increasing demands for product quality, how to efficiently and accurately complete the trimming operation has become a key concern for many manufacturers.

[0003] However, in existing thermoforming product trimming mechanisms, the cutting blade needs to continuously contact and cut the plastic product during the trimming process. Due to frequent friction, the blade inevitably wears down gradually, causing its sharpness to decrease. As the usage time increases, the wear intensifies. This not only makes it difficult for the cutting blade to cut the material smoothly, but also significantly reduces the quality of the trimming. Issues such as rough edges and uneven cuts become more pronounced, seriously affecting the appearance and quality of the thermoformed product. Because the cutting blade becomes dull, greater force needs to be applied during cutting, which not only increases the energy consumption of the equipment, but also slows down the cutting speed, greatly reducing the overall efficiency of trimming and slowing down the entire production process, making it unable to meet the ever-increasing production demands. Utility Model Content

[0004] The purpose of this utility model is to provide a forming and trimming mechanism for blister products. This forming and trimming mechanism solves the problem that the blade inevitably wears down due to the frequent friction between the cutting blade and the plastic product, resulting in a continuous decrease in its sharpness.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A forming and trimming mechanism for a thermoformed product includes a trimming machine, a movable frame slidably connected to the outside of the trimming machine, a telescopic cylinder slidably connected to the top of the movable frame, and a cutting blade fixedly mounted on the piston rod surface of the telescopic cylinder.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0030] A forming and trimming mechanism for a thermoformed product, such as Figures 1-6 As shown, it includes an edge trimming machine 1, a movable frame 2 is slidably connected to the outside of the edge trimming machine 1, a telescopic cylinder 3 is slidably connected to the top of the movable frame 2, and a cutting blade 4 is fixedly installed on the piston rod surface of the telescopic cylinder 3.

[0031] It also includes an active component 5 for polishing the surface of the cutting blade 4;

[0032] The extrusion component 6 is used to improve the polishing effect of the cutting blade 4;

[0033] First, the active component 5 includes: a fixed block 51, which is fixedly installed at the bottom of the telescopic cylinder 3. The piston rod of the telescopic cylinder 3 passes through the fixed block 51. A connecting block 52 is fixedly installed on the surface of the piston rod of the telescopic cylinder 3. A connecting plate 53 is hinged to the bottom of the fixed block 51. A grinding disc 54 is rotatably connected to the bottom of the connecting plate 53. A telescopic rod 55 is fixedly installed inside the fixed block 51. A fixing spring 56 is fixedly installed inside the telescopic rod 55. A fixing strip 57 is installed at the bottom of the telescopic rod 55. The fixing strip 57 is slidably connected to the surface of the connecting plate 53. A trigger rod 58 is fixedly installed at the bottom of the fixing strip 57. The fixing strip 57 can slide on the surface of the connecting plate 53 and abut against the connecting plate 53, so that the grinding disc 54 at the bottom can be attached to the surface of the cutting blade 4.

[0034] Secondly, a slide rod 510 runs through the inside of the fixed block 51, and a movable spring 511 is fixedly installed on the surface of the slide rod 510. The movable spring 511 is fixedly installed on the top of the fixed block 51, and a slide rod 512 is fixedly installed on the inner side of the slide rod 510. A rotating shaft 513 is rotatably connected to the top of the fixed block 51, and the slide rod 512 is slidably connected to the surface of the rotating shaft 513. The movable spring 511 on the surface of the slide rod 510 can achieve the effect of resetting when the slide rod 510 is not resisted.

[0035] Furthermore, a movable shaft 514 is connected to the surface of the rotating shaft 513 via a belt drive. A threaded rod 515 is fixedly installed at the bottom of the movable shaft 514. A slider 516 is threadedly connected to the surface of the threaded rod 515. The slider 516 is slidably connected to the inner side of the fixed block 51. A toothed plate 517 is hinged to the bottom of the slider 516. A gear 518 meshes on the surface of the toothed plate 517. The gear 518 is fixedly installed on the surface of the grinding disc 54. The toothed plate 517, which is hinged to the bottom of the slider 516, can move along with the gear 518 when the gear 518 moves.

[0036] In this embodiment, through the setting of the movable component 5, the telescopic cylinder 3 drives the cutting blade 4 to reset, so that the connecting block 52 pushes the trigger rod 58, causing the telescopic rod 55 to retract. At this time, the fixing strip 57 will slide at the inclined groove 531 opened on the surface of the connecting plate 53, thereby resisting the connecting plate 53 and moving closer to the surface of the cutting blade 4. When the rotating shaft 513 rotates, it will drive the movable shaft 514, the threaded rod 515, the slider 516 and the bottom toothed plate 517 to move downward through the belt. When the toothed plate 517 moves downward, it will drive the surface meshing gear 518 and the grinding disc 54 to rotate, thereby grinding the cutting blade 4 after use. This prevents the cutting blade 4 from frequently contacting and cutting the plastic product during the trimming process of the blister product, which would cause the blade to gradually wear down and its sharpness to decrease. This improves the quality and accuracy of trimming and enhances the efficiency of trimming. Example

[0037] like Figures 7-8 As shown, the extrusion assembly 6 includes: a movable strip 61, which is fixedly installed on the inner side of the slider 516, and a pressure strip 62 is slidably connected inside the movable strip 61, which passes through the connecting plate 53.

[0038] Furthermore, a lubricating oil bottle 63 is fixedly installed inside the connecting plate 53. The bottle opening of the lubricating oil bottle 63 extends through the bottom of the connecting plate 53. A piston disc 64 is connected to the piston inside the lubricating oil bottle 63. A moving rod 65 is fixedly installed on the top of the piston disc 64. A connecting spring 66 is fixedly installed on the surface of the moving rod 65. The connecting spring 66 is fixedly installed on the top of the lubricating oil bottle 63. The moving rod 65 can be reset after being pressed by the pressure bar 62 through the connecting spring 66 on the surface of the moving rod 65.

[0039] Finally, a groove 530 is provided at one end of the surface of the connecting plate 53, which allows the pressure strip 62 to slide inside the connecting plate 53. A slanted groove 531 is provided at the other end of the surface of the connecting plate 53, which allows the fixing strip 57 to move upward and abut against the connecting plate 53, swinging towards the surface of the material. An arc-shaped groove 5130 is provided on the surface of the rotating shaft 513, which allows the rotating shaft 513 to rotate when the sliding rod 512 slides. The cross-section of the fixing strip 57 is U-shaped, which improves the sliding effect on the surface of the connecting plate 53.

[0040] In this embodiment, by setting the moving component, when the slider 516 slides down, it will also drive the moving strip 61 and the pressure strip 62 to slide down inside the connecting plate 53. When the pressure strip 62 slides, it will abut against the top of the moving rod 65 and drive the piston plate 64 at the bottom of the moving rod 65 to slide down inside the lubricating oil bottle 63, thereby squeezing the lubricating oil inside the lubricating oil bottle 63 onto the surface of the grinding disc 54. By dripping the lubricating oil onto the surface of the grinding disc 54, the friction between it and the cutting blade 4 can be effectively reduced, preventing the grinding disc 54 from being worn excessively, improving the grinding effect on the cutting blade 4, and extending the service life of the grinding disc 54.

[0041] This utility model discloses a forming and trimming machine 1 for thermoforming products. In use, the plastic product is placed on the conveyor of the trimming machine 1. The motor drives the conveyor belt to output the material. During output, a hydraulic rod drives a movable frame 2 to slide on the surface of the trimming machine 1, allowing for front-to-back adjustment. When trimming the material, a telescopic cylinder 3 is activated to drive the cutting blade 4 downwards. The hydraulic rod also drives the telescopic cylinder 3 to slide at the top of the movable frame 2, cutting the material. After trimming, the telescopic cylinder 3 resets the cutting blade 4, causing the connecting block 52 on the surface of the telescopic cylinder 3 to push the trigger rod 58. When the trigger rod 58 is abutted, it causes the telescopic rod 55 to retract. When the telescopic rod 55 retracts, it causes the fixing strip 57 to slide at the inclined groove 531 on the surface of the connecting plate 53, thus moving the connecting plate 53 closer to the cutting blade 4. As the connecting plate 53 moves, it... The bottom grinding disc 54 moves in the same direction as the surface of the cutting blade 4. When the connecting block 52 moves upward, it will also abut against the bottom end of the slide rod 510. When the slide rod 510 is abutted and moves upward, it will drive the slide rod 512 to slide in the arc groove 5130 opened on the surface of the rotating shaft 513, thereby driving the rotating shaft 513 to rotate. When the rotating shaft 513 rotates, it will drive the rotating shaft 514 to rotate through the belt. When the rotating shaft 514 rotates, it will drive the threaded rod 515 to rotate. When the threaded rod 515 rotates, it will drive the slider 516 and the bottom toothed plate 517 to move downward on the surface of the threaded rod 515. When the toothed plate 517 moves downward, it will drive the meshing gear 518 to rotate. When the gear 518 rotates, it will drive the grinding disc 54 to rotate, thereby grinding the cutting blade 4 after use. This prevents the cutting blade 4 from frequently contacting and cutting the plastic product during the trimming process of the blister product, which would cause the blade to gradually wear down and its sharpness to decrease. If not sharpened in time, as wear intensifies, the cutting blade 4 will have difficulty cutting materials smoothly, thus failing to improve the quality and precision of edge trimming and enhance its efficiency.

[0042] When slider 516 slides downward, it also drives moving bar 61 to slide downward. When moving bar 61 slides downward, it drives pressure bar 62 to slide downward inside connecting plate 53. When pressure bar 62 slides, it abuts against the top of moving rod 65 and drives piston disc 64 at the bottom of moving rod 65 to slide downward inside lubricating oil bottle 63, thereby squeezing the lubricating oil inside lubricating oil bottle 63 onto the surface of grinding disc 54. When slider 516 slides upward, moving rod 65 will reset under the action of connecting spring 66 and be ready for the next use. Lubricating oil drips onto the surface of grinding disc 54 to prevent severe friction between grinding disc 54 and cutting blade 4 when grinding. Without the lubrication of lubricating oil, long-term friction can easily cause the abrasive on the surface of grinding disc 54 to wear out and fall off quickly, resulting in a decrease in grinding ability of grinding disc 54, accelerated wear, or even scrapping. By dripping lubricating oil onto the surface of the grinding disc 54, the friction between it and the cutting blade 4 can be effectively reduced, preventing excessive wear of the grinding disc 54, improving the grinding effect on the cutting blade 4, and extending the service life of the grinding disc 54.
