Description

Technical Field

[0001] The present invention relates to the technical field of sandblasting devices, and particularly relates to a sandblasting component and a sandblasting device. Background Art

[0002] Sandblasting is a process of cleaning and roughening the surface of a substrate by the impact of a high-speed sand flow. During operation, a sandblasting device uses compressed air as power to form a high-speed jet beam to spray abrasive materials (such as quartz sand, emery, iron sand, etc.) at a high speed onto the surface of the substrate to be processed, so that the surface of the substrate obtains a certain degree of cleanliness and different roughness under the impact and cutting action of the abrasive materials, thereby improving the mechanical properties of the substrate surface.

[0003] The sand pipe of a sandblasting device used in the medical field is extremely thin. If the abrasive materials are not screened or the screening is not in place, then foreign-shaped objects or large particles in the abrasive materials will cause the sand pipe to be blocked, resulting in a decrease in the sand flow rate or even no sand output. This causes the substrate to have poor quality or even be scrapped due to uneven sandblasting on its surface. Some existing sandblasting devices do not have a dredging mechanism. Once the sand pipe is blocked, manual dredging is required, increasing the labor cost. Summary of the Invention

[0041] To make the objectives, advantages, and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the objectives of the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0042] Figure 1The structural schematic diagram of the sandblasting assembly 10 provided according to an embodiment of the present invention is shown. As Figure 1 shown, the sandblasting assembly 10 includes a sand pipe 100, a sandblasting head 200, and a dredging mechanism (not labeled in the figure). One end of the sand pipe 100 is connected to the sandblasting head 200. The sand pipe 100 includes a first pipe section 101 (as Figure 4 shown), and the dredging mechanism includes a first sub-dredging mechanism (not labeled in the figure). The first sub-dredging mechanism includes a sand crushing structural member 311 (as Figure 4 and Figure 5 shown) and a driving member 312. The sand crushing structural member 311 is disposed in the first pipe section 101, and the driving member 312 is used to drive the sand crushing structural member 311 to reciprocate axially along the sand pipe 100 in the first pipe section 101. And / or, as Figure 1 shown, the sand pipe 100 includes a second pipe section 102, and the second pipe section 102 is different from the first pipe section 101. The dredging mechanism includes a second sub-dredging mechanism 320. The second sub-dredging mechanism 320 includes a collar 321 and a force applying member 322. The collar 321 is sleeved on the second pipe section 102, and the force applying member 322 is connected to the collar 321 and is used to apply a force to the second pipe section 102 through the collar 321 to deform the second pipe section 102.

[0043] The sandblasting assembly 10 is applied to a sandblasting device. As Figure 8 shown, the sandblasting device further includes a sand material supply mechanism 20. The outlet end of the sand material supply mechanism 20 is connected to the end of the sand pipe 100 away from the sandblasting head 200. The sand material supply mechanism 20 is used to make the sand material enter the sand pipe 100 and spray out at high speed from the sandblasting head 200. When the first pipe section 101 of the sand pipe 100 is blocked by large-particle sand material, the driving member 312 can be used to drive the sand crushing structural member 311 to move to crush the large-particle sand material, so as to dredge the first pipe section 101. And / or, when the second pipe section 102 of the sand pipe 100 is blocked by sand material, the second pipe section 102 is deformed by the action of the second sub-dredging mechanism 320, and then the sand material in the second pipe section 102 is pushed to move, so as to realize the dredging of the second pipe section 102. In other words, when the first pipe section 101 and / or the second pipe section 102 of the sand pipe 100 is blocked, the corresponding sub-dredging mechanism can be used for dredging, without manual dredging operation, saving manpower and reducing labor costs.

[0044] Next, the detailed structure of the sandblasting assembly 10 will be described.

[0045] Please refer to Figure 1 andFigure 4 When the sand pipe 100 includes both the first pipe section 101 and the second pipe section 102 at the same time, the first pipe section 101 may be closer to the sand blasting head 200 than the second pipe section 102. For example, in one implementation, one end of the first pipe section 101 is connected to the sand blasting head 200, and the end of the first pipe section 101 away from the sand blasting head 200 is connected to the second pipe section 102 by any suitable means.

[0046] Please refer to Figures 2 to 5 The sand pipe 100 includes a first pipe fitting 110, a first connecting piece 120, and a second pipe fitting 130. One end of the first pipe fitting 110 is connected to the sand blasting head 200. The second pipe fitting 130 is connected to the end of the first pipe fitting 110 away from the sand blasting head 200 through the first connecting piece 110. The second pipe fitting 130 wraps a part of the outer peripheral surface of the first connecting piece 120. The part of the second pipe fitting 130 located on the side away from the sand blasting head 200 of the first connecting piece 120 constitutes the first pipe section 101. Optionally, the first pipe fitting 110 wraps another part of the outer peripheral surface of the first connecting piece 120. That is, the first connecting piece 120 is completely blocked or wrapped by the first pipe fitting 110 and the second pipe fitting 120.

[0047] As Figure 6 and Figure 7 shown, the sand pipe 100 further includes a first hose 140 and a second hose 150. The second hose 150 is sleeved on the outer peripheral surface of the first hose 140 and is connected to the first hose 140. The first hose 140 and the second hose 150 together constitute the second pipe section 102. Such a design can improve the strength of the second pipe section 102 and extend its service life.

[0048] The first hose 140 and the second hose 150 can be connected in any suitable way. For example, in an optional implementation, the sand pipe 100 further includes a second connecting piece 160. The number of the second connecting pieces 160 is two, and the two second connecting pieces 160 are respectively connected to the axial two ends of the first hose 140. Each second connecting piece 160 is turned outwards and covers a part of the outer peripheral surface of the first hose 150. In this way, each end of the second hose 150 is stuck between the corresponding second connecting piece 160 and the first hose 140 and cannot be separated from the first hose 140. In addition, the second connecting piece 160 can be integrally formed with the first hose 140 or can be formed separately and then connected together.

[0049] Preferably, at least two groups of sand-breaking protrusions (not shown in the figure) are provided on the inner wall of the second pipe section 102, and the at least two groups of sand-breaking protrusions are arranged at intervals along the circumferential direction of the second pipe section 102. Each group of sand-breaking protrusions includes a plurality of sand-breaking protrusions 103, and all the sand-breaking protrusions 103 in the same group of sand-breaking protrusions are arranged at intervals along the axial direction of the second pipe section 102. When the second pipe section 102 is blocked and the force-applying member 322 applies a force to the second pipe section 102 to cause the second pipe section 102 to deform, the second pipe section 102 squeezes the sand grains through the sand-breaking protrusions 103 to crush the large sand materials with relatively small hardness, so that the sand materials blocked at the second pipe section 102 are more easily pushed.

[0050] Optionally, with particular reference to Figures 2 to 4 , the sand-breaking structural member 311 of the first sub-unclogging mechanism is configured to be magnetic. The driving member 312 includes a coil, and the coil is sleeved on at least a part of the outer peripheral surface of the first pipe section 101. The coil is used to generate an alternating magnetic field when energized, whereby the sand-breaking structural member 311 can be driven by magnetic force to reciprocate along the axial direction of the sand pipe 100 in the first pipe section 101. To make the sand-breaking structural member 311 magnetic, the sand-breaking structural member 311 can include a magnetic body, that is, the sand-breaking structural member 311 is at least partially made of a magnetic material.

[0051] In practice, the first sub-unclogging mechanism further includes a fixing frame 313, the fixing frame 313 is connected to the axial two ends of the second pipe fitting 130, and the coil is connected to the fixing frame 313 to prevent the coil from shifting.

[0052] Preferably, a shock pad (not shown in the figure) is provided at one end of the first connecting member 120 away from the sand blasting head 200. The sand crushing structural member 311 has two opposite ends, one end being close to the sand blasting head 200 and the other end being away from the sand blasting head 200. The end face of the end of the sand crushing structural member 311 away from the sand blasting head 200 is formed into a smooth curved surface, and the curved surface is smoothly connected to the side surface of the sand crushing structural member 311. The side surface of the sand crushing structural member 311 refers to the surface connecting the two ends on the sand crushing structural member 311. The advantage of such a setting is to reduce the impact of the sand crushing structural member 311 on the first pipe section 101 during the axial movement along the sand pipe 100 and extend the service life of the sand pipe 100. Additionally, it can be understood that when the sand crushing structural member 311 is entirely made of a magnetic material, that is, when the sand crushing structural member 311 is an integral magnetic body, in fact, the magnetic body has two opposite ends, one end being close to the sand blasting head 200 and the other end being away from the sand blasting head 200, and the end face of the end of the magnetic body away from the sand blasting head 200 is formed into a smooth curved surface.

[0053] Those skilled in the art know that the sand material flows along the sand pipe 100 under the push of compressed air. Optionally, a gas flow channel is provided on the sand crushing structural member 311 for the compressed air and some small particle sand materials to flow through. In some implementation manners, the sand crushing structural member 311 has an inner cavity, one end of the inner cavity is open, for example, one end of the inner cavity close to the sand blasting head 200 is open 314 (as Figure 5 shown), a plurality of through holes 315 are provided on the side surface of the sand crushing structural member 311, and the through holes 315 are communicated with the inner cavity and jointly form the gas flow channel.

[0054] The number of the second sub-unclogging mechanisms 320 is set according to the length of the second pipe section 102. When the length of the second pipe section 102 is small, only one second sub-unclogging mechanism 320 can be provided (as Figure 1 shown). When the length of the second pipe section 102 is large, two or more second sub-unclogging mechanisms 320 are provided as needed, and the sleeves 321 of all the second sub-unclogging mechanisms 320 are sleeved at different positions of the second pipe section 102. In this way, when different positions of the second pipe section 102 are blocked, the corresponding second sub-unclogging mechanisms 320 at the corresponding positions can be used for unclogging.

[0055] Optionally, please refer back to Figure 1, the force-applying member 322 of each of the second sub-unclogging mechanisms 320 is connected to a fixed member (such as the sand bin 21 mentioned later), and includes a telescopic rod 3221. The collar 321 is connected to the telescopic rod 3221. The force-applying member 322 applies a force to the second pipe section 102 through the elongation or shortening of the telescopic rod 3221. For example, if the second pipe section 102 is in an initial state when the length of the telescopic rod 3221 is the shortest, then when the telescopic rod 3221 elongates, the telescopic rod 3221 applies a pushing force to the second pipe section 102 through the collar 321. If the second pipe section 102 is in an initial state when the length of the telescopic rod 3221 is the longest, then when the telescopic rod 3221 shortens, the telescopic rod 3221 applies a pulling force to the second pipe section 102 through the collar 321. The force-applying member 322 can be a cylinder, and thus, the telescopic rod 3221 is the piston rod of the cylinder. Alternatively, the force-applying member 322 can also be an electric push rod, etc.

[0056] Please refer to Figure 2 and Figure 5 , a plurality of guiding protrusions 210 are provided on the inner surface of the sandblasting head 200, and all the guiding protrusions 210 are arranged at intervals along the axial direction of the sandblasting head 200. Each of the guiding protrusions 210 extends along the axial direction of the sandblasting head 200, and each of the guiding protrusions 210 is parallel to the axis of the sandblasting head 200. When sandblasting with this sandblasting head 200, the sand material can be ejected in a straight line, improving the sandblasting effect.

[0057] Furthermore, an embodiment of the present invention further provides a sandblasting device, as Figure 8 shown, the sandblasting device includes the sandblasting assembly 10 and a sand material supply mechanism 20. The sand material supply mechanism 20 is connected to one end of the sand pipe 100 away from the sandblasting head 200, and is used to supply sand material and compressed air to the sandblasting assembly 10, so that the sand material can be ejected at a high speed along the sand pipe 100 under the action of the compressed air.

[0058] Optionally, the abrasive supply mechanism 20 includes a sand bin 21 for accommodating abrasives, and the sand bin 21 is connected to one end of the sand pipe 100 away from the sand blasting head 200. A gas inlet passage 22 is further provided on the abrasive supply mechanism 20, and the gas inlet passage 22 communicates with a compressed air source and the sand bin 21. The compressed air provided by the compressed air source enters the sand bin 21 from the gas inlet passage 22, and pushes the abrasives in the sand bin 21 into the sand pipe 100, and then sprays out from the sand blasting head 200. In addition, a gas outlet passage 23 is provided on the abrasive supply mechanism 20, and the gas outlet passage 23 communicates with the sand bin 21. Compressed air can be discharged from the sand bin 21 through the gas outlet passage 23 to complete the pressure relief of the sand blasting equipment. Additionally, the force applying member 322 of the second sub-unclogging mechanism can be connected to the sand bin 21.

[0059] Further, the sand blasting equipment further includes a monitoring mechanism 400 (as Figure 9 shown), and the monitoring mechanism 400 is disposed at the sand blasting head 200 and is used to monitor sand blasting parameters. The sand blasting parameters at least include the actual sand blasting flow rate. Further, the sand blasting parameters may further include the sand blasting duration, the actual total amount of sand blasted during sand blasting, etc. Generally speaking, when the sand pipe 100 is blocked, the actual sand blasting flow rate will be less than the preset rated sand blasting flow rate, and the actual total amount of sand blasted will be less than the set rated total amount of sand blasted (when the sand blasting parameters include the actual total amount of sand blasted). Therefore, it is possible to determine whether the sand pipe 100 is blocked based on the sand blasting parameters, and then determine whether it is necessary to control the first sub-unclogging mechanism and / or the second sub-unclogging mechanism to work.

[0060] Further, the sand blasting equipment further includes a control unit 30 (as Figure 9 shown), and the control unit 30 is communicatively connected to the monitoring mechanism 400 and the unclogging mechanism, and is configured to receive the sand blasting parameters, determine whether the sand pipe 100 is blocked according to the sand blasting parameters, and control the unclogging mechanism to work to unclog the sand pipe 100 when the sand pipe 100 is blocked.

[0061] When the sand pipe 100 simultaneously includes the first pipe section 101 and the second pipe section 102, the dredging mechanism simultaneously includes the first sub-dredging mechanism and the second sub-dredging mechanism 320, and the number of the second sub-dredging mechanisms 320 is more than two, the control unit 30 controlling the dredging mechanism to work means controlling the first sub-dredging mechanism to work, or controlling one of the second sub-dredging mechanisms 320 to work. That is to say, the control unit 30 controls only one sub-dredging mechanism to work at a time. After the sub-dredging mechanism has worked for a predetermined time, if the sand pipe 200 is still blocked, then the control unit 30 controls another sub-dredging mechanism to work.

[0062] Specifically, there are multiple preset positions on the second pipe section 102, the number of the preset positions is equal to the number of the second sub-dredging mechanisms, and the collar 321 of each second sub-dredging mechanism 320 is sleeved at one of the preset positions. The control unit 30 determines the dredging priority of each part according to the blockage frequency of the first pipe section 101 and each of the preset positions, and then controls the corresponding sub-dredging mechanism to work according to the dredging priority when the sand pipe 100 is blocked. For example, assume that there are two preset positions, namely the first preset position and the second preset position, and the blockage frequency of the first pipe section 101 is the highest, the blockage frequency of the first preset position is the second highest, and the blockage frequency of the second preset position is the third highest. Then it is determined that the dredging priority of the first pipe section 101 is the highest, the dredging priority of the first preset position is the second highest, and the dredging priority of the second preset position is the lowest. Thus, when the sand pipe 100 is blocked, the control unit 30 first controls the first sub-dredging mechanism to work. After the first sub-dredging mechanism has worked for a predetermined time, if the sand pipe 100 is still blocked, the control unit 30 then controls the second sub-dredging mechanism 320 corresponding to the first preset position (that is, the collar 321 of this second sub-dredging mechanism 320 is sleeved at the first preset position) to work. After this second sub-dredging mechanism 320 has worked for a predetermined time, if the sand pipe 100 is still blocked, the control unit 30 then controls the second sub-dredging mechanism 320 corresponding to the second preset position (that is, the collar 321 of this second sub-dredging mechanism 320 is sleeved at the second preset position). Controlling the corresponding sub-dredging mechanism to work successively according to the blockage frequency can not only dredge the sand pipe 100, but also improve the dredging efficiency, and is beneficial to saving energy and reducing the operation cost.

[0063] Optionally, after each dredging of the sand pipe 100, the control unit 30 stores historical data, which includes the clogging position information of the sand pipe 100 in the current clogging. Specifically, when the first sub-dredging mechanism works for a predetermined time, if the sandblasting parameters monitored by the monitoring mechanism 400 return to normal, that is, when the actual sandblasting flow rate reaches the rated sandblasting flow rate and the actual total sandblasting amount reaches the rated total sandblasting amount, the control unit 30 can determine that the current dredging is completed, and the position where the sand pipe 100 is clogged in the current clogging is the first pipe section 101. Therefore, the control unit 30 marks the first pipe section 101 and stores it as the clogging position information of the current clogging. When the second sub-dredging mechanism 320 corresponding to the first preset position works for a predetermined time and the sandblasting parameters monitored by the monitoring mechanism 400 return to normal, then the control unit 30 can determine that the current dredging is completed, and the position where the sand pipe 100 is clogged in the current clogging is the first preset position. Therefore, the control unit 30 marks the first preset position and stores it as the clogging position information of the current clogging. When the second sub-dredging mechanism 320 corresponding to the second preset position works for a predetermined time and the sandblasting parameters monitored by the monitoring mechanism 400 return to normal, then the control unit 30 can determine that the current dredging is completed, and the position where the sand pipe 100 is clogged in the current clogging is the second preset position. Therefore, the control unit 30 marks the second preset position and stores it as the clogging position information of the current clogging. After that, the control unit 30 can determine the clogging frequencies of the first pipe section 101 and each of the preset positions according to the historical data.

[0064] It can be seen that, as Figure 9As shown in the figure, the control unit 30 includes a plurality of functional modules, namely a control terminal module 31, a parameter acquisition module 32, a storage module 33, a data inference module 34, an execution module 35, and a marking module 36. Among them, the control terminal module 31 is communicatively connected to the abrasive supply mechanism 20 and the parameter acquisition module 32, and controls the parameter acquisition module 32 to work when the abrasive industrial mechanism 20 is started. The parameter acquisition module 32 is communicatively connected to the monitoring mechanism 400 and is used to receive the sandblasting parameters monitored by the monitoring mechanism 400. The storage module 33 pre-stores the rated sandblasting parameters, the historical data, and the dredging priority. The rated sandblasting parameters include the rated sandblasting flow rate, the rated total sandblasting volume, etc. The data inference module 34 is communicatively connected to the parameter acquisition module 32 and the storage module 33, and determines whether the sand pipe 100 is blocked or dredged according to the actual sandblasting parameters and the rated sandblasting parameters. Specifically, when the actual sandblasting flow rate is less than the rated sandblasting flow rate and / or the total sandblasting volume is less than the rated total sandblasting volume, it is determined that the sand pipe 100 is blocked, and when the actual sandblasting flow rate reaches the rated sandblasting flow rate and / or the actual total sandblasting volume reaches the rated total sandblasting volume, it is determined that the sand pipe 100 is not blocked or has been dredged. The data inference module 34 is also used to determine the blockage position after each dredging is completed. After the data inference module 34 determines that the sand pipe 100 is blocked, the execution module 35 controls the corresponding sub-dredging mechanism to work according to the dredging priority to dredge the sand pipe 100. The marking module 36 is communicatively connected to the data inference module 34 and the storage module 33, and is used to mark the blockage position during each blockage to generate the blockage position information, and send the blockage position information to the storage module 33 for storage.

[0065] In summary, in the technical solution provided by the embodiments of the present invention, by equipping the sandblasting assembly with a dredging mechanism, when the sand pipe is blocked, the blocked part of the sand pipe can be dredged by the dredging mechanism, without manual operation, saving manpower and reducing the operating cost of the sandblasting equipment. By monitoring the sandblasting parameters through the monitoring mechanism, and the control unit determines whether the sand pipe is blocked according to the current sandblasting parameters, and controls the dredging mechanism to work according to the historical data when the sand pipe is blocked, the blocked sand pipe can be dredged quickly and effectively, and it is also beneficial to save energy and further reduce the operating cost of the sandblasting equipment.
