Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically a sandblasting machine umbrella-shaped sand distribution mechanism. Background Technology

[0002] In modern coating production lines, sandblasting machines achieve efficient reuse of abrasive materials through a cyclical process of sandblasting, recycling, separation, and reuse, greatly reducing production costs. Among these methods, airflow separation is a commonly used abrasive separation technique. It utilizes wind or airflow to separate the abrasive materials, dust, and impurities mixed after sandblasting. Pure abrasive materials that meet the particle size requirements are then screened out through gravity and airflow for reuse.

[0003] However, existing sandblasting machines using airflow-based sand separation have significant drawbacks. When the amount of separated sand is insufficient to meet continuous sandblasting needs, the sandblasting machine must pause operations and wait for the equipment to restart the sand separation process to replenish the sand. Since sandblasting and sand separation / feeding cannot be synchronized, feeding during sandblasting disrupts the pressure balance within the sandblasting chamber, affecting the sandblasting effect and posing safety hazards. Conversely, during sand separation / feeding, the sandblasting equipment must be stopped to ensure operational safety and accuracy. This results in substantial idle time during operation, directly leading to a significant reduction in the efficiency of the coating production line. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an umbrella-shaped sand-distributing mechanism for a sandblasting machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sandblasting machine umbrella-shaped sand-distributing mechanism, including a support frame, and further comprising:

[0006] The sand separating component, which is mounted on a support frame, is used to separate sand and dust impurities.

[0007] The feeding component, which is set on the sand distribution component, is used to replenish sand separately;

[0008] The sand separating component includes a sand separating tank, which is fixed to the top of the support frame. Both sides of the sand separating tank are connected to feed pipes, the bottom of the sand separating tank is connected to a sand outlet pipe, the top of the inner cavity of the sand separating tank is fixed to an umbrella-shaped plate, the middle of the umbrella-shaped plate is fixed to a sand separating pipe, and the top of the sand separating tank is connected to an air extraction pipe.

[0009] The feeding assembly includes a feeding hopper, which is fixed to one side of the sand separating tank. The bottom of the feeding hopper is connected to a flexible hose. A feeding trough is provided on one side of the sand separating tank. A baffle is slidably connected to the outer side of the feeding trough. A handle is fixed to one side of the baffle. A slot is provided on one side of the baffle. A sliding groove is provided inside the support frame. A limiting shaft is slidably connected inside the sliding groove. A fixing ring is fixed to the outer surface of the limiting shaft. A return spring is sleeved on the outer surface of the limiting shaft.

[0010] As described above, the bottom end of the sand-distributing pipe passes through the umbrella-shaped plate and extends to the outside of the umbrella-shaped plate, and the top end of the sand-distributing pipe passes through the sand-distributing tank and is connected to the air extraction pipe.

[0011] As described above, the outer end of the exhaust pipe is connected to an external negative pressure fan, the feed pipe feeds sand into the sand separator through a high-pressure fan, and the bottom of the sand separator is conical.

[0012] As described above, the bottom end of the baffle passes through the support frame and is slidably connected to the support frame, the inner wall of the baffle closes to the feed chute, and the top surface of the support frame blocks the bottom of the handle.

[0013] As described above, the bottom end of the hose is fixed to the baffle, and the hose is initially blocked by the outer wall of the sand separator.

[0014] As mentioned above, when the baffle moves downward, the hose communicates with the feed trough.

[0015] As described above, the reset spring is elastically supported between the slide groove and the fixed ring, and the limiting shaft is movably engaged with the slot.

[0016] Compared with existing technologies, this umbrella-shaped sand-distributing mechanism for sandblasting machines has the following advantages:

[0017] I. This utility model, through the cooperation between the baffle and the feed chute, allows the bottom end of the hose to move downwards when there is insufficient sand inside the sand separator, so that the hose can be connected to the sand separator. At this time, the support frame will block the handle, so the sand inside the sand separator can be replenished through the feed hopper, saving time.

[0018] II. This utility model uses two sets of feed pipes to input sand and high-pressure airflow into the sand separating tank. At this time, the high-pressure airflow will form a rotating airflow inside the sand separating tank, which will create centrifugal force on the sand, throwing larger particles towards the inner wall of the sand separating tank. Since the sand separating pipe is located in the middle of the sand separating tank, dust and other impurities are extracted inside, completing the separation of sand. The separated sand will gather at the bottom of the inner cavity of the sand separating tank, and be extracted from the sand outlet pipe by sandblasting equipment. Two sets of spray guns are connected to the bottom of the sand outlet pipe to improve the sandblasting efficiency.

[0025] 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.

[0026] like Figure 1-4 As shown, this utility model provides an umbrella-shaped sand-distributing mechanism for a sandblasting machine, including a support frame 1, and further comprising:

[0027] The sand separating component is mounted on the support frame 1 and is used to separate sand and dust impurities.

[0028] The feeding component, which is set on the sand distribution component, is used to replenish sand separately;

[0029] The sand separating component includes a sand separating tank 2, which is fixed to the top of the support frame 1. Both sides of the sand separating tank 2 are connected to feed pipes 3, the bottom of the sand separating tank 2 is connected to a sand outlet pipe 5, the top of the inner cavity of the sand separating tank 2 is fixed to an umbrella-shaped plate 6, the middle of the umbrella-shaped plate 6 is fixed to a sand separating pipe 7, and the top of the sand separating tank 2 is connected to an air extraction pipe 8.

[0030] The feeding assembly includes a feeding hopper 9, which is fixed to one side of the sand separating tank 2. The bottom of the feeding hopper 9 is connected to a flexible hose 10. A feeding trough 13 is provided on one side of the sand separating tank 2. A baffle 11 is slidably connected to the outside of the feeding trough 13. A handle 12 is fixed to one side of the baffle 11. A slot 4 is provided on one side of the baffle 11. A sliding groove 15 is provided inside the support frame 1. A limiting shaft 16 is slidably connected inside the sliding groove 15. A fixing ring 17 is fixed to the outer surface of the limiting shaft 16. A reset spring 14 is sleeved on the outer surface of the limiting shaft 16.

[0031] Sand and high-pressure airflow are fed into the sand separator 2 through two sets of feed pipes 3. The high-pressure airflow will form a rotating airflow inside the sand separator 2, which will create centrifugal force on the sand and throw larger particles toward the inner wall of the sand separator 2. Since the sand separator pipe 7 is located in the middle of the sand separator 2, it will extract dust and other impurities inside, thus completing the separation of the sand. The separated sand will gather at the bottom of the inner cavity of the sand separator 2 and be extracted from the sand outlet pipe 5 using a sandblasting device. When there is not enough sand at the bottom of the inner cavity of the sand separator 2, the bottom end of the hose 10 can be moved downward by the cooperation between the baffle 11 and the feed chute 13, so that the hose 10 is connected to the sand separator 2. At this time, the support frame 1 will block the handle 12, so the sand can be replenished inside the sand separator 2 through the feed hopper 9, saving time.

[0032] like Figure 3 As shown, the bottom end of the sand separating pipe 7 passes through the umbrella-shaped plate 6 and extends to the outside of the umbrella-shaped plate 6, and the top end of the sand separating pipe 7 passes through the sand separating tank 2 and is connected to the air extraction pipe 8.

[0033] By designing the sand separating pipe 7, the sand will be located on the inner wall of the sand separating tank 2 due to the influence of centrifugal force. The sand separating pipe 7 is located in the middle of the inner cavity of the sand separating tank 2, so it can extract lighter dust impurities and separate the sand.

[0034] like Figure 1 , 3 As shown, the outer end of the exhaust pipe 8 is connected to an external negative pressure fan, and the feed pipe 3 feeds sand into the sand separator 2 through a high-pressure fan. The bottom of the sand separator 2 is conical.

[0035] By designing the air extraction pipe 8, negative pressure can be used to extract the gas inside the sand separator 2, thereby removing dust and impurities.

[0036] like Figure 1 , 3As shown, the bottom end of the hose 10 is fixed to the baffle 11, and the hose 10 is blocked by the outer wall of the sand separator 2 in the initial state. The top of the support frame 1 blocks the bottom of the handle 12. When the baffle 11 moves downward, the hose 10 communicates with the feed trough 13. The bottom end of the baffle 11 passes through the support frame 1 and is slidably connected to the support frame 1. The inner wall of the baffle 11 closes to the feed trough 13.

[0037] The cooperation between the baffle 11 and the support frame 1 allows the baffle 11 to slide along the inner side of the support frame 1, thereby moving the hose 10 to the position of the feed trough 13 and connecting it with the sand separator 2.

[0038] like Figure 4 As shown, the reset spring 14 is elastically supported between the slide groove 15 and the fixed ring 17, and the limiting shaft 16 is movably engaged with the slot 4.

[0039] The spring force of the return spring 14 can push the fixed ring 17 to move along the inner side of the slide groove 15, so that the fixed ring 17 can drive the limiting shaft 16 to engage with the return spring 14, so that the baffle 11 can be positioned and the baffle 11 can seal the feed groove 13.

[0040] Working principle:

[0041] Sand and high-pressure airflow are fed into the sand separator 2 through two sets of feed pipes 3. The high-pressure airflow will form a rotating airflow inside the sand separator 2, which will create centrifugal force on the sand and cause the sand to be thrown against the inner wall of the sand separator 2. Then, dust and other impurities inside the sand separator 2 are extracted through the air extraction pipe 8 and the sand separator pipe 7, thus completing the separation of sand. When there is insufficient sand at the bottom of the inner cavity of the sand separator 2 and sandblasting is required, the bottom end of the hose 10 can be moved downward by the cooperation between the baffle 11 and the feed chute 13, so that the hose 10 is connected to the sand separator 2. Therefore, sand can be added to the inside of the sand separator 2 through the feed hopper 9.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
