Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to a sandblasting machine for sandblasting and cleaning gun drill bits. Background Technology

[0002] Currently, sandblasting machines used for cleaning gun drill bits on the market can only clean a limited number of gun drill bits at a time. Furthermore, after cleaning a single gun drill bit, it needs to be disassembled before the next one can be cleaned, resulting in low efficiency when cleaning a large number of gun drill bits. Utility Model Content

[0003] This invention addresses the problem that current sandblasting cleaning processes for gun drill bits require removing the cleaned drill bit after cleaning and reinstalling the uncleaned drill bit before continuing with the cleaning of the uncleaned drill bit. This presents a sandblasting machine that allows for the cleaning of the next uncleaned drill bit immediately after cleaning without disassembly and reinstallation, thus improving the cleaning efficiency of gun drill bits.

[0004] The technical solution adopted in this utility model is:

[0005] A sandblasting machine for cleaning gun drill bits is provided, comprising: a support base with a conveying mechanism and a driving mechanism on its top, the driving mechanism driving the conveying mechanism to operate and transport in a ring; a housing located on top of the support base, with an inlet and an outlet respectively opened on opposite side walls of the housing; the conveying mechanism passing through the inlet and outlet of the housing; a flushing mechanism located on the inner top of the housing; and multiple connecting seats respectively located on the conveying mechanism, the multiple connecting seats being driven by the conveying mechanism to move circumferentially; each connecting seat having a support plate on its top, and each support plate having a clamping mechanism for holding the gun drill bit; wherein the inlet and outlet are both passable by each support plate.

[0006] Optionally, each support plate is located directly above the conveying mechanism and has a gap between it and the conveying mechanism to cover the conveying mechanism.

[0007] Optionally, a feed cylinder and a discharge cylinder are respectively provided on the side wall of the box. The inside of the feed cylinder is connected to the feed port, and the inside of the discharge cylinder is connected to the discharge port. Two first switch doors are hinged on the inner wall of the feed cylinder away from the box, and the two first switch doors are used to seal the opening of the feed cylinder. Two second switch doors are hinged on the inner wall of the discharge cylinder away from the box, and the two second switch doors are used to seal the opening of the discharge cylinder. A torsion spring is provided at the hinge between each first switch door and the inner wall of the feed cylinder, and at the hinge between each second switch door and the inner wall of the discharge cylinder.

[0008] Optionally, each support plate has an arc-shaped stop at its top edge.

[0012] Optionally, an observation opening is provided on the side wall of the enclosure, and an observation window is provided at the observation opening.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a conveying mechanism, the drill bits to be cleaned are fixed to the clamping mechanism on each support plate. Then, the conveying mechanism is activated, transporting the connecting seats holding the drill bits until they enter the interior of the housing through the feed inlet. At this point, the conveying mechanism inside the housing starts operating and cleans the drill bits held by the clamping mechanism. After the clamping mechanism has finished cleaning the drill bits, the conveying mechanism resumes operation, sending the cleaned drill bits out through the discharge outlet of the housing. Then, the uncleaned drill bits are fed back into the housing through the feed inlet for cleaning. The cleaned drill bits can then be removed from a different location than the housing when another drill bit is being cleaned, thus improving the cleaning efficiency of the drill bits.

[0031] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0032] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example

[0034] Please see Figure 1-5 As shown, this embodiment discloses a sandblasting machine for sandblasting and cleaning gun drill bits, comprising:

[0035] The support base 1 has a conveying mechanism 2 and a driving mechanism on its top. The driving mechanism is used to drive the conveying mechanism 2 to run and transport in a ring shape.

[0036] The housing 3 is located on top of the support base 1, and the opposite side walls of the housing 3 are respectively provided with a feed inlet and a discharge outlet; the conveying mechanism 2 passes through the feed inlet and discharge outlet of the housing 3; the inner top of the housing 3 is provided with a rinsing mechanism 30.

[0037] Multiple connecting seats 21 are respectively mounted on the conveying mechanism 2, and the conveying mechanism 2 drives the multiple connecting seats 21 to move in a circumferential direction; each connecting seat 21 is provided with a support plate 22 on its top, and each support plate 22 is provided with a clamping mechanism for clamping the gun drill bit.

[0038] Both the inlet and outlet can accommodate the passage of each support plate 22.

[0039] Specifically, the drill bits are mounted on the clamping mechanism of each connecting seat 21. Then, the drive mechanism drives the conveying mechanism 2, which in turn moves the connecting seat 21 circumferentially. Once the connecting seat 21 enters the housing 3 through the feed inlet, the drive mechanism stops, and the conveying mechanism 2 also stops. The connecting seat 21 then remains inside the housing 3. Next, the flushing mechanism 30 inside the housing 3 is activated, cleaning the drill bits clamped on the clamping mechanism. It should be noted that the flushing mechanism 30 used in this embodiment is a prior art flushing mechanism for sandblasting drill bits, well-known to those skilled in the art, and will not be elaborated further here. During the sandblasting cleaning of the drill bits by the flushing mechanism 30, the housing 3 provides protection, preventing sand particles from flying out of the housing 3 through the feed inlet and outlet. After the drill bit has been sandblasted, the drive mechanism is activated, which in turn drives the conveyor mechanism 2. The conveyor mechanism 2 then sends the cleaned drill bit out of the housing 3 through its outlet. Next, the next uncleaned drill bit is fed into the housing 3 for further cleaning. Cleaned drill bits can be disassembled after being conveyed out of the housing 3 via the conveyor mechanism 2, without delaying the sandblasting of the remaining uncleaned drill bits. In this embodiment, dust particles falling during the sandblasting of the drill bits accumulate at the bottom of the housing 3. Once a significant amount has accumulated, it can be cleaned. Furthermore, an exhaust port (not shown in the figure) is provided at the top of the housing 3 to balance the internal air pressure. It should be noted that in this embodiment, the drive mechanism can be a motor with an output shaft at its output end. This output shaft drives the conveyor mechanism 2. This is prior art for those skilled in the art and will not be elaborated further here.

[0040] Furthermore, each of the aforementioned support plates 22 is located directly above the conveying mechanism 2. In this embodiment, the conveying mechanism 2 is specifically a chain conveying mechanism 2, and each connecting seat 21 is spaced apart on the chain 20 of the chain conveying mechanism 2. Since the chain 20 in the chain conveying mechanism 2 is located inside the housing 3, and the sand particles splashed during the sandblasting cleaning of the drill bit by the cleaning mechanism inside the housing 3 will affect the chain 20, thereby affecting the transmission of the chain 20. Therefore, it is necessary to ensure that the support plates 22 provided on the chain 20 can block the chain 20 inside the housing 3 after entering the housing 3. That is, the connecting seat 21 is located between the chain 20 and the cleaning mechanism, and there is a gap between it and the chain 20 to avoid affecting the transmission effect of the chain 20.

[0041] Feed cylinder 4 and discharge cylinder 5 are respectively provided on opposite side walls of the aforementioned housing 3. The interior of feed cylinder 4 is connected to the feed inlet, and the interior of discharge cylinder 5 is connected to the discharge outlet. Specifically, two first switch doors 40 are hinged to the inner wall of feed cylinder 4. A torsion spring is provided at the hinge point between the two first switch doors 40 and feed cylinder 4. The two first switch doors 40 are used to seal the inlet of feed cylinder 4. When the conveying mechanism 2 drives the support plate 22 to enter the housing 3 through feed cylinder 4, the support plate 22 presses the two first switch doors 40, and the two first switch doors 40 are pushed open by the support plate 22. When the support plate 22 is fully inside the housing 3, the support plate 22 will no longer press the two first switch doors 40, and the two first switch doors 40 will rebound under the action of the torsion spring, thereby sealing the inlet of feed cylinder 4. Similarly, two second switch doors 50 are hinged to the inner wall of the discharge cylinder 5. A torsion spring is also provided at the hinge between the two second switch doors 50 and the discharge cylinder 5, which is used to seal the outlet of the discharge cylinder 5. When the conveying mechanism 2 runs and drives the support plate 22 to be sent out from the inside of the box 3 through the discharge port, the support plate 22 will squeeze the two second switch doors 50. After being squeezed, the two second switch doors 50 will rotate and open until the support plate 22 is completely out of the inside of the box 3. At this time, the two second switch doors 50 are no longer squeezed and will rebound under the action of the torsion spring, thereby sealing the outlet of the discharge cylinder 5.

[0042] Sealing gaskets 7 are provided on the closing surfaces of the two first switching doors 40 and the two second switching doors 50. The sealing gaskets 7 enable the two first switching doors 40 and the two second switching doors 50 to achieve a better sealing effect when closed. In addition, through holes 8 are provided on the two first switching doors 40 and the two second switching doors 50 for the conveying mechanism 2 to pass through, so that the conveying mechanism 2 can deliver the drill bit into the interior of the housing 3.

[0043] Each of the aforementioned support plates 22 has an arc-shaped stop 23 at its top edge. When the cleaning mechanism performs sandblasting cleaning on the drill bit inside the housing 3, sand particles may splash. The arc-shaped stop 23 can block most of the splashed sand particles, preventing excessive sand particles from falling onto the chain 20 and affecting its use.

[0044] An emergency window 31 is provided on the side wall of the aforementioned housing 3, and a hinged door 33 is connected to the emergency window 31, allowing personnel to open the door 33 to repair or replace the cleaning mechanism inside the housing 3. In addition, an observation port 32 is provided on the side wall of the housing 3, and an observation window 34 is provided at the observation port 32, so that personnel can observe the sandblasting cleaning of the drill bit inside the housing 3.

[0045] The top of the aforementioned support base 1 is equipped with a protective cover 6, which is connected to both the inlet and outlet of the housing 3. The protective cover 6 serves to prevent excessive dust particles from adhering to the drill bit when it enters the housing 3 for cleaning, and also to prevent dust particles from remaining on the surface of the drill bit after cleaning, thus reducing the cleaning effect. It is important to note that the two ends of the protective cover 6 are not connected to each other, leaving space for disassembling and assembling the drill bit.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
