Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to a sandblasting core for a sandblasting machine. Background Technology

[0002] In the field of surface treatment equipment, sandblasting machines achieve functions such as rust removal, deburring, and strengthening by impacting the workpiece surface with high-speed abrasive. The sandblasting core, as the core component driving the accelerated movement of the abrasive, directly affects the processing efficiency and operational stability of the equipment. In existing technologies, sandblasting cores mostly adopt a one-piece shell or a multi-component welded structure. Internally, they typically feature a single-cavity impeller or blade assembly. Driven by a motor, the impeller rotates, generating centrifugal force to draw the abrasive in through the feed inlet and then accelerate it out. To achieve directional guidance of the abrasive, some sandblasting cores are equipped with a fixed baffle structure to constrain the abrasive's trajectory and ensure precise application to the workpiece surface.

[0003] However, existing sandblasting cores have certain drawbacks in use: First, most existing sandblasting cores are non-separable integral structures or multi-component welded moldings. Core working parts such as impellers, blades, and partition guides are rigidly connected to the shell. When any component is worn, deformed, or malfunctions due to sand impact, the entire sandblasting core must be replaced because it is impossible to disassemble and replace a single damaged part individually. This results in a large number of undamaged components being discarded simultaneously, significantly increasing spare parts procurement costs. Moreover, the equipment downtime during the overall replacement process is longer, indirectly causing a loss of production efficiency. Second, the single-cavity design makes it easy for sand to be unevenly distributed and move erratically inside. Some sand is not accelerated sufficiently due to uneven force, which reduces the uniformity of surface treatment.

[0004] In view of this, a sandblasting core for a sandblasting machine is designed. Utility Model Content

[0005] The purpose of this utility model is to provide a sandblasting core for a sandblasting machine to solve the problems of existing sandblasting cores mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sandblasting core for a sandblasting machine, comprising: Two sets of outer plates are connected to each other by a number of sets of internal hexagonal bolts and external hexagonal nuts; A geared motor is installed on the outside of one set of the outer plates; A guide baffle is connected between the two sets of outer plates; Two sets of inner plates are movable between two sets of outer plates. A bushing connects the two sets of inner plates. The output end of the geared motor is fixedly connected to one set of inner plates and the bushing. Several groups of partition strips are arranged in a regular circular array between two groups of inner plates. The two groups of inner plates and the several groups of partition strips are fixedly connected by several groups of internal hexagonal bolts and nuts. Among them, a group of first feed holes are formed in a regular ring array in the body of a group of outer plates away from the geared motor, and a group of second feed holes are formed in the body of a group of inner plates away from the geared motor.

[0007] Preferably, the guide baffle has a "U" shaped structure, and the front and rear sides of the guide baffle are provided with several sets of protrusions at equal intervals.

[0008] Preferably, the outer plate has a plurality of slots extending through it, and the plurality of protrusions are respectively adapted to be inserted into the plurality of slots.

[0009] Preferably, the guide baffle includes: Semi-circular part; Two sets of straight sections are integrally connected to both ends of the semi-circular section; The semi-ring portion is a semi-ring structure, and the straight portion is a cuboid structure.

[0010] Preferably, the partition strip is an arc-shaped structure, and the inner sides of the two sets of inner plates are connected to the bushing by several partition strips to form several sets of sand material dynamic zones.

[0011] Preferably, the inner plate has several sets of material release grooves equidistantly spaced at its edge (the material release grooves are arc-shaped).

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) This application features a detachable structure where the two outer panels are fixedly connected by hexagonal bolts and hexagonal nuts. Simultaneously, internal components such as the inner panel and partition strips are detachably connected using bolts and nuts. Compared to traditional integrated or welded structures, when components experience wear or failure, it is not necessary to disassemble the entire device; component replacement can be completed simply by removing the corresponding bolts, significantly shortening maintenance time and reducing operating costs. Furthermore, the guide baffle, through a protrusion that fits into the slot of the outer panel, enables rapid positioning and installation, further improving assembly efficiency. 2) This application sets up a regular ring array of arc-shaped partition strips between two sets of inner plates, which, together with the bushing, form several independent sand material power zones. This allows the sand material to be distributed to each power zone after entering through the first feed hole and the second feed hole. When the geared motor drives the inner plates and partition strips to rotate, the sand material in each power zone can obtain a balanced centrifugal force, effectively avoiding the problems of disordered sand material movement and uneven acceleration in traditional single cavities, improving the consistency of sand material ejection speed, and thus enhancing the uniformity and efficiency of workpiece surface treatment.

[0013] 3) The guide baffle of this application adopts a "U" shaped structure, which can accurately constrain the movement trajectory of the sand and ensure that the sand is discharged from the sand power zone along the preset path. The arc-shaped material release groove opened on the edge of the inner plate can guide and release the sand stuck on the edge of the inner plate, ensuring the continuity and stability of sand conveying.

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.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a sandblasting core for a sandblasting machine, comprising: Two sets of outer plates 1 are connected by several sets of internal hexagonal bolts and external hexagonal nuts; The geared motor 2 is installed on the outside of one of the outer plates 1; Guide baffle 3 is connected between the two sets of outer plates 1; Two sets of inner plates 4 are movable between two sets of outer plates 1. A bushing 6 is connected between the two sets of inner plates 4. The output end of the geared motor 2 is fixedly connected to one of the sets of inner plates 4 and the bushing 6. Several groups of partition strips 5 are arranged in a regular circular array between two groups of inner plates 4. The two groups of inner plates 4 and the several groups of partition strips 5 are fixedly connected by several groups of internal hexagonal bolts and nuts. Among them, a group of first feed holes 102 are opened in a regular ring array in the outer plate 1 that is far away from the geared motor 2, and a group of second feed holes 402 are opened in the inner plate 4 that is far away from the geared motor 2.

[0020] Specifically, the two outer plates 1 are fixedly connected by several sets of internal hexagonal bolts and external hexagonal nuts to form a detachable split structure. Compared with the traditional integral or welded structure, when the internal components are worn, there is no need to replace the entire sandblasting core. Only the bolts need to be removed to repair or replace the damaged parts individually, which greatly reduces maintenance costs and spare parts consumption.

[0021] Specifically, the geared motor 2 consists of a drive motor and a reducer. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer provides rotational power to the inner plate 4, ensuring that the inner plate 4 drives the partition strips 5 to rotate stably. The guide baffle 3 is connected between the two sets of outer plates 1, providing a stable initial guiding path for the abrasive. In conjunction with the first feed hole 102 of the outer plate 1 and the second feed hole 402 of the guide baffle 3, the abrasive can enter the internal cavity in an orderly manner, that is, enter the abrasive power zone 7, avoiding abrasive collision and loss caused by disordered feeding. Several sets of partition strips 5 are fixed in a regular circular array between the two sets of inner plates 4. This not only facilitates the individual replacement of worn partition strips 5, but also forms several independent abrasive power zones 9 together with the inner plate 4 and the bushing 6, allowing the abrasive to obtain uniform centrifugal force during rotation, improving the consistency of the abrasive ejection speed, and thus enhancing the uniformity of the workpiece surface treatment.

[0022] Reference manual attached Figure 3-5 The guide baffle 3 has a U-shaped structure, and several sets of protrusions 303 are equidistantly arranged on its front and rear sides. Specifically, the U-shaped structure of the guide baffle 3 can form a wrapping guide for the sand, effectively constraining the movement trajectory of the sand and preventing it from deviating to the sides during transportation. This ensures that more sand accurately enters the sand power zone 7, improving sand utilization. The several sets of protrusions 303 equidistantly arranged on the front and rear sides of the guide baffle 3 can enhance the connection strength with the outer plates 1 on both sides. Compared with planar contact, the contact area between the protrusions 303 and the outer plates 1 is larger and the force is more uniform, which can effectively resist the radial force generated by the impact of sand, reduce the vibration and loosening of the guide baffle 3, and extend the service life of the guide baffle 3. At the same time, the regular distribution of the protrusions 303 also provides a positioning benchmark for the installation of the guide baffle 3, simplifying the calibration steps in the assembly process and improving assembly efficiency.

[0023] Specifically, a circular through hole for the bushing 6 to pass through is provided at the center of a set of outer plates 1 away from the geared motor 2.

[0024] Specifically, a through hole is provided at the center of a set of inner plates 4 away from the geared motor 2, and the through hole is connected to the second feed hole 402.

[0025] Reference manual attached Figure 2-3The outer plate 1 has several sets of slots 101 extending through it, and several sets of protrusions 303 are respectively adapted to be inserted into the slots 101. Specifically, the slots 101 in the outer plate 1 and the protrusions 303 of the guide baffle 3 form a matching insertion structure. This insertion fit achieves pre-fixation between the guide baffle 3 and the outer plate 1, ensuring the accurate installation position of the guide baffle 3 before subsequent bolt tightening and avoiding displacement deviation during assembly. In addition, this insertion structure facilitates the quick disassembly of the guide baffle 3. When the guide baffle 3 is worn, it can be directly pulled out and replaced after disassembling the corresponding components, without cumbersome disassembly steps, thus shortening maintenance time.

[0026] Reference manual attached Figure 3-5 The guide baffle 3 includes: Semi-ring 301; Two sets of straight sections 302 are integrally connected to both ends of the semi-circular section 301; Among them, the semi-ring part 301 is a semi-ring structure, and the straight part 302 is a cuboid structure.

[0027] Specifically, the semi-circular portion 301 of the guide baffle 3 has a semi-circular structure that conforms to the circular motion trajectory of the sand, forming an arc-shaped guide for the incoming sand, reducing the frictional resistance between the sand and the baffle, and lowering the kinetic energy loss of the sand. The two sets of straight sections 302 are cuboid structures integrally connected to both ends of the semi-circular portion 301, guiding the sand in a straight segment, precisely directing the sand to the inlet and outlet of the sand power zone 7, preventing sand accumulation or jamming at bends. The integral molding structure of the semi-circular portion 301 and the straight sections 302 enhances the overall rigidity of the guide baffle 3. Compared to a spliced ​​structure, it has stronger resistance to deformation, can withstand the continuous impact of sand for a long time while maintaining structural stability, and ensures consistent guiding effect.

[0028] Specifically, the semi-circular portion 301 of the guide baffle 3 can significantly extend the movement path of the sand during the guiding stage, thereby increasing the material's movement time. This allows the sand more time to adapt to the rotating centrifugal force field before entering the straight section 302, gradually completing the transition from the initial feeding state to the accelerated movement state, reducing collisions and congestion between sand particles caused by sudden changes in movement state. Simultaneously, the semi-circular portion 301 can continuously apply guiding force to the sand through its curved surface, allowing the sand to gradually accumulate kinetic energy over the extended movement time, resulting in a more stable pre-acceleration effect.

[0029] Reference manual attached Figure 5The partition strip 5 has an arc-shaped structure, and several sand material dynamic zones 7 are formed on the inner sides of the two sets of inner plates 4 through several partition strips 5 and bushings 6. Specifically, when the sand material dynamic zone 7 rotates to the inner side of the semi-ring 301, it forms a relatively closed area. The partition strip 5 adopts an arc-shaped structure, so that both sides of the several sand material dynamic zones 7 formed on the inner sides of the two sets of inner plates 4 through partition strips 5 and bushings 6 are arc-shaped. When the geared motor 2 drives the inner plates 4 and partition strips 5 to rotate and generate centrifugal force, the sand material will naturally generate a tendency to move towards the arc-shaped structure on one side of the sand material dynamic zone 7 under the action of centrifugal force. This tendency is adapted to the guiding characteristics of the arc-shaped surface, so that the sand material can slide smoothly along the arc-shaped side, reducing the rigid collision between the sand material and the partition strip 5. Compared with the power zone with a straight edge structure, the arc-shaped sides can guide the sand material to gradually fit the arc-shaped surface during the movement, disperse the impact force of the sand material on the partition strip 5, reduce the wear rate of the partition strip 5, and extend its service life. Meanwhile, as the abrasive moves along the curved surface, the centrifugal force acts more evenly and continuously, enabling the abrasive to achieve a more stable acceleration effect within the abrasive power zone 7. This avoids speed fluctuations caused by collisions, ensuring consistent speed when the abrasive is ejected, thereby improving the uniformity and efficiency of workpiece surface treatment. The regularly arranged circular array of abrasive power zones 7, combined with the guiding trend of the abrasive on both sides of the curve, further ensures the balance of abrasive distribution in each power zone, reduces local abrasive congestion, and improves the overall operational stability of the sandblasting machine core.

[0030] Reference manual attached Figure 3 and instruction manual attached Figure 5-6 Several sets of material release grooves 401 are equidistantly provided along the edge of the inner plate 4. The material release grooves 401 are arc-shaped. Specifically, when sand gets stuck at the edge of the inner plate 4 due to inertia or collision during its entry into the sand power zone 7, the arc-shaped material release grooves 401 can use the rotational force of the inner plate 4, the guiding force of the groove surface, and the mutual collision and pushing action of the sand to smoothly guide the stuck sand into the sand power zone 7, preventing sand from accumulating at the edge of the inner plate 4. At the same time, the equidistantly distributed material release grooves 401 are compatible with the regular array of the partition strips 5, further improving the accuracy of sand distribution and ensuring the overall operating efficiency of the sandblasting machine core.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
