Technical Field
[0001] This utility model relates to the field of shot blasting machine technology, specifically to a shot material uniform sorting device for shot blasting machines. Background Technology
[0002] Shot blasting machines are mechanical devices that use high-speed projectiles of metal abrasive to impact and treat the surface of workpieces. They are mainly used for surface cleaning, strengthening, deburring, and pretreatment. The shot used in shot blasting machines needs to be sorted during use, and this sorting requires a shot uniform sorting device. Currently, shot sorting in shot blasting machines still has the following shortcomings:
[0003] 1. Existing shot blasting machine sorting devices cannot effectively remove small particles of dust and other impurities from the shot, which will affect the quality of the shot used.
[0004] 2. In existing shot blasting machine sorting devices, shot tends to accumulate at the edge of the screen, which affects the sorting effect of the shot;
[0005] 3. The screens of existing shot blasting machine sorting devices are prone to clogging, which leads to a decrease in grading accuracy.
[0006] To address the aforementioned issues, we have made innovative designs based on the existing structure of the shot uniform sorting device for shot blasting machines. Utility Model Content
[0007] The purpose of this invention is to provide a uniform shot sorting device for shot blasting machines, in order to solve the problems mentioned in the background art, such as the inability of existing shot blasting machine sorting devices to effectively clean small particles of dust and other impurities in the shot, the easy accumulation of shot at the edge of the screen, and the easy clogging of the screen.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine shot uniform sorting device, comprising a sorting bin, wherein a feed inlet is fixedly connected to the upper end of the sorting bin; a discharge outlet is opened at the bottom of the sorting bin; an ash discharge trough is opened inside the sorting bin; a filter screen is fixedly installed inside the sorting bin; a dust removal component is disposed inside the sorting bin; and a striking component is disposed at the bottom of the filter screen; wherein the dust removal component is used to clean dust from the shot; and the striking component is used to strike the filter screen to make it vibrate.
[0009] Preferably, the filter screen has a multi-layer composite structure, and an elastic buffer layer is provided on the inner side of the filter screen.
[0010] By adopting the above technical solution, the elastic buffer layer is made of polyurethane porous board, which absorbs impact and uniformly transmits vibration.
[0011] Preferably, the dust removal assembly includes a drive motor, a fan blade, and a first gear. The drive motor is fixedly installed on the outside of the sorting bin, and the output end of the drive motor passes through the inside of the sorting bin. The output end of the drive motor is fixedly connected to the fan blade, which is located inside the sorting bin. The output end of the drive motor is fixedly connected to the first gear, which is considered to be a half-tooth structure.
[0012] By adopting the above technical solution, wind power can be generated by the rotation of the fan blades.
[0013] Preferably, the dust removal assembly further includes a chute, a telescopic spring, a sliding block, and a rack. The chute is located inside the sorting chamber, and a telescopic spring is fixedly connected to the inside of the chute. A sliding block is fixedly connected to the tail end of the telescopic spring, and the sliding block is slidably connected to the inside of the chute. A rack is fixedly connected to the outside of the sliding block, and the rack meshes with an outer first gear.
[0014] By adopting the above technical solution, the sliding block can be automatically reset by the elastic force of the telescopic spring.
[0015] Preferably, the dust removal assembly further includes a second gear, a concentric shaft, and a guide plate. The concentric shaft is rotatably connected to the inner side of the sorting chamber, and multiple sets of concentric shafts are provided. The top of the concentric shaft is fixedly connected to the second gear, and the second gear meshes with the outer rack. The outer side of the concentric shaft is fixedly connected to the guide plate, and the guide plate is located inside the sorting chamber.
[0016] By adopting the above technical solution, the range of wind power and dust removal can be increased by setting up the deflector.
[0017] Preferably, the striking assembly includes a third gear, a drive shaft, and a cam. The drive shaft is rotatably connected to the inside of the sorting chamber, and the third gear is fixedly connected to the outside of the drive shaft. The third gear meshes with the outer first gear. The cam is fixedly connected to the outside of the drive shaft, and the cam and the filter screen are distributed vertically in correspondence.
[0018] By adopting the above technical solution, the third gear can be driven to rotate through the meshing of the first gear and the third gear.
[0019] Preferably, the striking assembly further includes a spiral spring, the two ends of which are connected to the inner wall of the sorting chamber and the cam respectively, and the preload of the spiral spring is in the opposite direction to the rotation direction of the cam.
[0020] By adopting the above technical solution, the cam on the outside of the drive shaft can be rotated by the elastic force of the spiral spring.
[0021] Compared with the prior art, the beneficial effect of this utility model is that the shot blasting machine's shot uniform sorting device is equipped with:
[0022] 1. Dust removal structure: When dust in the shot needs to be removed, the drive motor is activated, which drives the fan blades to rotate. The rotation of the fan blades generates wind, which blows the lighter dust in the shot into the dust discharge trough, thereby achieving the effect of dust removal.
[0023] Furthermore, when the output end of the drive motor rotates, it synchronously drives the first gear of the outer half-gear to rotate. When the tooth surface of the first gear contacts the rack, it drives the rack to move to the side and compresses the telescopic spring. The movement of the rack to the side drives the second gear meshing on the outside to rotate. The rotation of the second gear drives the guide plate on the outside of the outer concentric shaft to rotate. When the tooth surface of the first gear separates from the rack, the rack will be reset by the elastic force of the telescopic spring, thereby driving the second gear to rotate in the opposite direction. Through the above structure, the guide plate swings back and forth, making the airflow scan in a fan shape, covering 100% of the filter area, and increasing the dust capture rate by 20%~35%, thereby improving the dust removal effect.
[0024] 2. Screening Structure: After dust removal, the shot falls onto the upper part of the filter screen. When the first gear tooth surface meshes with the third gear tooth surface, it drives the cam on the outside of the drive shaft to rotate and causes the scroll spring to store force. When the cam head faces upward, it strikes the bottom of the filter screen. When the first gear tooth surface separates from the third gear tooth surface, the cam on the outside of the drive shaft will be reset by the elastic force of the scroll spring. Through the above structure, when the cam rotates, its eccentric profile will periodically strike the filter screen, causing the screen surface to generate high-frequency micro-amplitude vibration. The vibration can break the "bridging effect" of shot accumulation, prompting qualified shot to pass through the mesh quickly, thereby achieving the effect of screening the shot.

[0032] 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.
[0033] Please see Figures 1-6 This utility model provides a technical solution: a shot blasting machine shot uniform sorting device, comprising:
[0034] Example 1: As Figures 1-4 , Figure 6 The present invention provides a technical solution: a uniform sorting device for shot blasting machine, comprising: a sorting bin 1, with a feed inlet 2 fixedly connected to the upper end of the sorting bin 1; a discharge outlet 3, which is located at the bottom of the sorting bin 1; an ash discharge trough 4, which is located inside the sorting bin 1; and a filter screen 5, which is fixedly installed inside the sorting bin 1.
[0035] Dust removal component 6 is installed inside the sorting chamber 1; tapping component 7 is installed at the bottom of the filter screen 5; wherein, dust removal component 6 is used to clean dust in the pellets; tapping component 7 is used to tap the filter screen 5 to make it vibrate.
[0036] The filter screen 5 has a multi-layer composite structure, and an elastic buffer layer is provided on the inner side of the filter screen 5; the dust removal assembly 6 includes a drive motor 601, a fan blade 602, and a first gear 603. The drive motor 601 is fixedly installed on the outside of the sorting chamber 1, and the output end of the drive motor 601 passes through the inside of the sorting chamber 1. The output end of the drive motor 601 is fixedly connected to the fan blade 602, and the fan blade 602 is located inside the sorting chamber 1. The output end of the drive motor 601 is fixedly connected to the first gear 603, and the first gear 603 is considered to be a half-tooth structure; the dust removal assembly 6 also includes a slide 604, a telescopic spring 605, a sliding block 606, and a rack 607. The slide 604 is opened inside the sorting chamber 1, and the inner side of the slide 604 is fixedly connected to the first gear 603. A telescopic spring 605 is fixedly connected to the dust removal assembly 6. A sliding block 606 is fixedly connected to the tail end of the telescopic spring 605. The sliding block 606 is slidably connected to the inner side of the slide groove 604. A rack 607 is fixedly connected to the outer side of the sliding block 606, and the rack 607 meshes with the outer first gear 603. The dust removal assembly 6 also includes a second gear 608, a concentric shaft 609, and a guide plate 610. The concentric shaft 609 is rotatably connected to the inner side of the sorting chamber 1, and multiple sets of concentric shafts 609 are provided. The second gear 608 is fixedly connected to the top of the concentric shaft 609, and the second gear 608 meshes with the outer rack 607. The guide plate 610 is fixedly connected to the outer side of the concentric shaft 609, and the guide plate 610 is located inside the sorting chamber 1.
[0037] When dust in the shot needs to be removed, this structure operates the drive motor 601, which drives the fan blade 602 to rotate. The rotation of the fan blade 602 generates wind, which blows the lighter dust particles in the shot into the dust discharge trough 4, thus achieving the dust removal effect. Simultaneously, the rotation of the drive motor 601 also drives the first gear 603 on the outer half of the gear to rotate. When the tooth surface of the first gear 603 contacts the rack 607, it causes the rack 607 to move to the side and compresses the telescopic spring 605. Moving 07 to the side will cause the outer meshing second gear 608 to rotate. The rotation of the second gear 608 will cause the guide plate 610 on the outer side of the outer concentric shaft 609 to rotate. When the tooth surface of the first gear 603 separates from the rack 607, the rack 607 will be reset by the elastic force of the telescopic spring 605, thereby causing the second gear 608 to rotate in the opposite direction. Through the above structure, the guide plate 610 will swing back and forth, so that the airflow will scan in a fan shape, covering 100% of the filter screen 5 area and increasing the dust capture rate by 20%~35%, thereby improving the dust removal effect.
[0038] Example 2: Figures 1-5The present invention provides a technical solution: a shot blasting machine shot uniform sorting device, which discloses that: the striking component 7 includes a third gear 701, a transmission shaft 702 and a cam 703. The transmission shaft 702 is rotatably connected to the inner side of the sorting chamber 1, and the third gear 701 is fixedly connected to the outer side of the transmission shaft 702. The third gear 701 meshes with the outer first gear 603. The cam 703 is fixedly connected to the outer side of the transmission shaft 702, and the cam 703 and the filter screen 5 are distributed vertically and vertically. The striking component 7 also includes a spiral spring 704. The two ends of the spiral spring 704 are respectively connected to the inner wall of the sorting chamber 1 and the cam 703, and the preload direction of the spiral spring 704 is opposite to the rotation direction of the cam 703.
[0039] After dust removal, the shot falls onto the top of the filter screen 5. When the tooth surface of the first gear 603 meshes with the tooth surface of the third gear 701, it drives the cam 703 on the outside of the drive shaft 702 to rotate and causes the spiral spring 704 to store force. When the head of the cam 703 faces upward, it will strike the bottom of the filter screen 5. When the tooth surface of the first gear 603 separates from the tooth surface of the third gear 701, the cam 703 on the outside of the drive shaft 702 will be reset by the elastic force of the spiral spring 704. Through the above structure, when the cam 703 rotates, its eccentric profile will periodically strike the filter screen 5, causing the screen surface to generate high-frequency micro-amplitude vibration. The vibration can break the "bridging effect" of the shot accumulation, and promote the qualified shot to pass through the mesh quickly, thereby achieving the effect of screening the shot.
