Abstract
Description
Technical Field
[0001] This utility model relates to the field of test tube processing, and in particular to a test tube forming and pressing device. Background Technology
[0002] Open-face glassware such as test tubes and centrifuge tubes are essential basic experimental instruments in the fields of chemistry, biology, and medicine. Their production mainly relies on test tube molding equipment. This equipment softens the glass tube blank by localized heating and then presses it into shape using upper and lower molds to form the sealed bottom structure of the test tube. In existing molding processes, when the upper and lower molds close to compress the softened glass tube bottom, some glass material is squeezed out from the gap between the molds, resulting in an excess burr or waste material around the top edge of the bottom of the test tube. This phenomenon is an unavoidable byproduct of current molding processes.
[0003] Currently, the industry typically addresses this issue by removing burrs through a separate, offline polishing process after the test tube has fully cooled and set. However, cooled glass burrs are hard and brittle, making them prone to micro-cracks or incomplete breakage during subsequent polishing, resulting in burrs or sharp edges. This not only affects the smoothness and flatness of the test tube opening, posing a risk of scratching users, but also may become the starting point for breakage due to stress concentration during subsequent use, affecting the product's safety and reliability.
[0004] Therefore, a test tube forming molding device was designed. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a test tube molding and pressing device. It solves the problem that in the existing test tube molding process, the pressing and pressing process creates a ring of burrs at the bottom of the test tube, which is inefficient and prone to causing micro-cracks and burrs on the product, affecting the smoothness of the mouth and the safety of use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A test tube molding and pressing device includes a worktable, a placement tray disposed on the worktable for placing test tubes, a scraper rotatably disposed on the placement tray for cleaning up burrs and waste, and a motor disposed inside the worktable for driving the placement tray to rotate.
[0007] Preferably, a protective ring is fixedly provided at the top edge of the placement tray, and a feeding groove is provided on the protective ring, with a sealing plate slidably arranged inside the feeding groove.
[0008] Preferably, a central rod is provided at the top center of the placement tray, and at least two sets of slots are provided on the central rod.
[0009] Preferably, the slots are arranged in a longitudinal linear pattern, and the bottom of the central rod is fixedly provided with a locking ring that engages with the placement disk.
[0010] Preferably, the scraper is arc-shaped, and a connecting ring that is sleeved with the central rod is fixedly provided at its center.
[0011] Preferably, two symmetrical connecting seats are fixedly provided on the outer wall of the connecting ring.
[0012] Preferably, the connecting ring has two symmetrical hooks on its outside, and a locking block is fixedly provided at one end of each hook.
[0013] Preferably, the locking block is made of rubber and engages with the locking slot; the side of the locking hook away from the locking block is provided with a damping hinge that is hinged to the connecting seat.
[0014] Preferably, a support base is fixedly provided on the top of the workbench, an mounting base is installed on the support base, a mounting plate is fixedly provided on the bottom of the mounting base, and an electric cylinder is provided on the bottom of the mounting plate.
[0015] Preferably, the output end of the electric cylinder and the mounting plate are connected by a mold to control the mold to press down for molding.
[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention improves the efficiency of flash removal by using a placement disc and a scraper in combination. After molding, the device drives the placement disc to rotate the high-temperature test tubes via a motor, while the scraper scrapes the flash. This integrates the original time-consuming independent grinding process into the continuous production cycle, significantly shortening the production time. The hot scraping principle effectively improves product quality. The scraper removes the flash while it is still red-hot and softened, effectively avoiding micro-cracks, chipping, and stress concentration problems caused by traditional cold grinding after cooling. This results in a smooth and flat bottom sealing edge of the test tube, reducing safety hazards and quality defects. The scraper height can be quickly adjusted by the cooperation of the locking block and the different height slots on the center rod. The damping hinge gives the scraper a certain degree of self-adaptability, allowing it to stably conform to the contours of test tubes of different sizes. This enables automated and precise processing of flash for multiple products on a single device. The scraper can also be removed from the center rod for cleaning and replacement.

[0024] Please see Figure 1-5 A test tube molding and pressing device includes a workbench 1, a placement tray 4 set on the workbench 1 for placing test tubes, a scraper 5 rotatably set on the placement tray 4 for cleaning up burrs and waste, and a motor set inside the workbench 1 for driving the placement tray 4 to rotate. A protective ring 41 is fixedly installed at the top edge of the placement tray 4. A material feeding groove 411 is provided on the protective ring 41. A sealing plate is slidably installed inside the material feeding groove 411. A central rod 42 is provided at the top center of the placement tray 4. At least two sets of slots 421 are provided on the central rod 42. The slots 421 are arranged in a longitudinal linear pattern. A snap ring 422 is fixedly installed at the bottom of the central rod 42 to engage with the placement tray 4.
[0025] The scraper 5 is arc-shaped, and a connecting ring 51 fitted onto the center rod 42 is fixedly installed at its center. Two symmetrical connecting seats 511 are fixedly installed on the outer wall of the connecting ring 51. Two symmetrical hooks 52 are installed on the outside of the connecting ring 51. A locking block 521 is fixedly installed at one end of the hook 52. The locking block 521 is made of rubber and engages with the locking groove 421. A damping hinge 522 is installed on the side of the hook 52 away from the locking block 521 and is hinged to the connecting seat 511. A support base 2 is fixedly installed on the top of the workbench 1. An mounting base 3 is installed on the support base 2. An mounting plate 31 is fixedly installed on the bottom of the mounting base 3. An electric cylinder 32 is installed on the bottom of the mounting plate 31. The output end of the electric cylinder 32 and the mounting plate 31 are connected through a mold 33 to control the mold 33 to press down for molding.
[0026] After the electric cylinder 32 drives the mold 33 to complete the compression molding of the test tube, the test tube, which is still in a high-temperature state, is transferred or placed directly on the placement tray 4. At this time, the motor inside the workbench 1 is started, which drives the placement tray 4 and the test tube to rotate together. The operator presses down the scraper 5, so that its connecting ring 51 moves down along the central rod 42 and is fixed by the rubber block 521 at one end of the hook 52 with the slot 421 arranged longitudinally on the central rod 42, thereby fixing the height of the arc-shaped scraper 5, so that its cutting edge contacts the flash at the bottom of the rotating test tube. Under the action of the damping hinge 522, the scraper 5 can make a slight adaptive adjustment to ensure that it fits the contour of the test tube. The rotating test tube sends the flash waste generated at the bottom of its bottom due to the compression of the mold, which is still in a red-hot and softened state, to the cutting edge of the scraper 5, where it is scraped off smoothly and continuously. The scraped-off waste is blocked by the protective ring 41 and finally discharged through its discharge groove 411.
[0027] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
