Description

Technical Field

[0001] This utility model relates to the technical field of drum-type shot blasting machines, and in particular to a drum-type shot blasting machine specifically designed for fully automatic loading and unloading of fasteners. Background Technology

[0002] After long-term use, fasteners are prone to developing impurities such as residual sand and oxide scale on their surface. In order to recycle and clean these fasteners and remove the impurities from their surface for subsequent reuse, a large number of fasteners with impurities are often put into a drum-type shot blasting machine. The centrifugal force of the rotating drum causes the shot to remove the impurities attached to the surface of the fasteners through collision. Therefore, a special drum-type shot blasting machine is often used when cleaning impurities from a large number of fasteners.

[0003] To address this, patent specification CN221020474U discloses an energy-saving drum-type shot blasting machine, relating to the field of shot blasting machine technology. The machine includes a base plate, a drum unit, and an energy-saving unit. The base plate has a rectangular plate structure, with the lower ends of two supports fixedly connected to the left and right ends of its upper surface, respectively. The drum unit includes a drum, reinforcing strips, an inner grid, and a lid assembly. The upper ends of the two supports are rotatably connected to the drum, and reinforcing strips are sleeved around the drum. The left end of the inner grid is fixedly connected to the left end of the drum's interior. The lid assembly is installed on the right end of the drum's upper surface. The energy-saving unit is installed on the left end of the base plate's upper surface. The lid assembly includes a connecting block, a rotating shaft, and a lid. The lower end of the connecting block is fixedly connected to the right end of the upper surface of the drum, and the right end of the connecting block is rotatably connected to the rotating shaft. This energy-saving drum-type shot blasting machine can fully utilize the kinetic energy when the device stops to save energy and ensures uniform impact and good cleaning effect between the internal shot and the workpiece. While the above-mentioned drum-type shot blasting machine is convenient to use, some problems still exist.

[0004] When the aforementioned drum-type shot blasting machine is in use, excessively high drum speeds can easily cause varying degrees of vibration, resulting in insufficient mixing and impact between the shot and the fasteners. Utility Model Content

[0005] The purpose of this invention is to provide a fully automatic roller-type shot blasting machine for fasteners, which solves the problem that the existing roller-type shot blasting machines have excessively high rotation speeds, which can easily lead to roller instability and thus affect the mixing and impact between the shot and the fasteners.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fully automatic fastener loading and unloading special drum-type shot blasting machine, including a main frame and a protective outer frame. The protective outer frame is flipped and connected to the upper part of the inner side of the main frame. A material lifting device assembly is installed at one end of the main frame. A screening structure is installed at the bottom inside the main frame. A filter drum is rotatably connected inside the protective outer frame. A material collection frame is provided at the bottom of the protective outer frame. An auxiliary structure is provided on the outer side of the filter drum. The auxiliary structure includes grid strips, a drive rod, a pulley assembly, a guide ring, a limiting guide wheel, a gear ring, a drive gear, a feeding rod, a feeding impeller, a guide groove, a push-pull rod, a hinged rotating sleeve, a hinged rod, and a hydraulic telescopic rod. The grid strips are fixedly connected to the inner wall of the filter drum.

[0007] In use, place the fasteners and shot on top of the feeder assembly. When the feeder assembly is started, the fasteners and shot are fed into the inside of the filter drum. Then, start the motor connected to the drive rod to make the filter drum rotate. The shot and fasteners inside the filter drum collide with each other under the action of centrifugal force. This causes the impurities and dirt on the surface of the fasteners to gradually fall off due to the collision and be discharged downward through the holes inside the filter drum, thus completing the cleaning of the fasteners.

[0008] Preferably, the screening structure includes a collection frame, side frames, guide frames, screening frames, springs, transmission rods, and cams. The collection frame is installed at the bottom of the inner side of the main frame. Side frames are fixedly connected to the top of both ends of the collection frame. Guide frames are fixedly connected to both ends of both sides of the collection frame. Screening frames are provided above the collection frame. Springs are provided on both sides of the collection frame. Transmission rods are rotatably connected to the inner side of the side frames. Cams are fixedly connected to both ends of the outer side wall of the transmission rod.

[0009] Preferably, the guide frames are symmetrically distributed about the vertical center line of the collection frame, and the screening frame and the guide frames have a sliding structure, so as to make the shaking of the screening frame more stable.

[0010] Preferably, the two ends of the spring are elastically connected to the collection frame and the screening frame via hooks, so that the screening frame can shake up and down stably.

[0011] Preferably, a drive rod is rotatably connected to the inner wall of the protective frame. One end of the drive rod extends through to the outer side of the protective frame and is fixedly connected to one end of the pulley assembly. A guide ring is fixedly connected to one end of the outer wall of the filter drum. A limit guide wheel is rotatably connected to one end of the outer wall of the drive rod. A gear ring is fixedly connected to the other end of the outer wall of the filter drum. A drive gear is fixedly connected to the other end of the drive rod. A feeding rod extends through the interior of one end of the filter drum. A feeding impeller is fixedly connected to one end of the feeding rod. Guide grooves are provided at one end of both sides of the main frame. Push-pull rods are fixedly connected to one end of both sides of the protective frame. A hinged rotating sleeve is rotatably connected to one side of the outer wall of the push-pull rod. A hinged rod is hinged to the top of the hinged rotating sleeve. Hydraulic telescopic rods are fixedly connected to the upper sides of both sides of the main frame. Under the drive of the motor, several symmetrically distributed drive gears can stably drive the filter drum to rotate.

[0012] Preferably, the grid strips are arranged in a ring on the inner wall of the filter drum, and the gear ring and the drive gear have a gear meshing structure, so as to enable the filter drum to rotate stably.

[0013] Preferably, the feed rod and the interior of one end of the filter drum have a rotating structure, and the top end of the hinge rod and the bottom end of the hydraulic telescopic rod have a hinge structure, so that when the bottom of the hydraulic telescopic rod extends up and down, it can push the push-pull rod to move, and thus drive the protective frame to rotate at a certain angle.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the motor drive causes the drive rod to rotate through the meshing of several drive gears and gear rings, and the rotation of the filter drum is made more stable under the rolling structure of the guide ring and several limit guide wheels, thereby avoiding the shaking of the filter drum during rotation. At the same time, during the rotation of the filter drum, the shot and the residue on the surface of the fasteners fall into the screening frame for shaking and screening.

[0015] 1. When the motor drives the drive rod to rotate, the drive gear drives the filter drum to rotate through meshing with the gear ring, and the rolling of the guide ring and the limit guide wheel prevents the filter drum from shaking during rotation;

[0016] At the same time, the intermittently driven hydraulic telescopic rod pushes and pulls the hinge rod. Under the hinge of the hinge rod, the push-pull rod slides along the guide groove, thereby causing the protective frame to drive the filter roller to rotate intermittently at a certain angle, thereby improving the collision between the shot and the fastener.

[0017] Furthermore, when it is necessary to unload the cleaned fasteners, tilt the filter roller to a certain angle so that the fasteners gradually roll to the front end. After the unloading impeller rotates, the filter cylinder can be gradually pushed outward to unload the fasteners.

[0018] 2. Start the motor connected to the transmission rod to make the transmission rod drive the cam to rotate, so that the screening frame is lifted up during the rotation of the cam, and under the elastic action of the spring, the screening frame shakes up and down stably, so that the shot and impurities are gradually separated for recycling.

Detailed Implementation

[0026] 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.

[0027] Please see Figures 1-6This utility model provides a fully automatic roller-type shot blasting machine for fasteners, including a main frame 1 and a protective outer frame 2.

The two ends of the spring 405 are elastically connected to the collection frame 401 and the screening frame 404 through hooks.

[0028] See attached document Figure 1 , Figure 3 and Figure 4 When this drum-type shot blasting machine is in use, the shot and fasteners roll and gradually collide inside the filter drum 5, thereby causing impurities attached to the surface of the fasteners to gradually fall off. The fallen impurities fall through the holes inside the filter drum 5 and through the collection frame 7 into the screening frame 404. The shot inside the filter drum 5 also gradually falls off during the rolling process of the filter drum 5. In order to separate the shot from the impurities for recycling, the screening frame 404 slides through the guide frame 403. The motor connected to the transmission rod 406 is started, which drives the cam 407 to rotate. The screening frame 404 is lifted up during the rotation of the cam 407, and under the elastic action of the spring 405, the screening frame 404 shakes up and down stably, so that the shot and impurities are gradually separated for recycling.

[0029] An auxiliary structure 6 is provided on the outer side of the filter drum 5. The auxiliary structure 6 includes grid bars 601, a drive rod 602, a pulley assembly 603, a guide ring 604, a limiting guide wheel 605, a gear ring 606, a drive gear 607, a feeding rod 608, a feeding impeller 609, a guide groove 610, a push-pull rod 611, a hinged rotating sleeve 612, a hinged rod 613, and a hydraulic telescopic rod 614. The grid bars 601 are fixedly connected to the inner wall of the filter drum 5. The inner wall of the protective frame 2 is rotatably connected to the drive rod 602. One end of the drive rod 602 extends through to the outer side of the protective frame 2 and is fixedly connected to one end of the pulley assembly 603. One end of the outer wall of the filter drum 5 is fixedly connected to the guide ring 604. One end of the outer wall of the drive rod 602 is rotatably connected to the limiting guide wheel 605. The other end of the outer wall of the filter drum 5 is fixedly connected to the gear ring 604. The other end of the drive rod 602 is fixedly connected to the wheel ring 606 and the drive gear 607. The filter drum 5 has a feeding rod 608 running through its interior. The feeding rod 608 is fixedly connected to a feeding impeller 609. The two sides of the main frame 1 are each fitted with a guide groove 610. The two sides of the protective outer frame 2 are each fixedly connected to a push-pull rod 611. The outer side of the push-pull rod 611 is rotatably connected to a hinge sleeve 612. The top of the hinge sleeve 612 is hinged to a hinge rod 613. The upper sides of the main frame 1 are each fixedly connected to a hydraulic telescopic rod 614. The grid bars 601 are distributed in a ring on the inner side wall of the filter drum 5. The gear ring 606 and the drive gear 607 have a gear meshing structure. The feeding rod 608 and the interior of one end of the filter drum 5 have a rotating structure. The top of the hinge rod 613 and the bottom of the hydraulic telescopic rod 614 have a hinge structure.

[0030] See attached document Figure 2 , Figure 5 and Figure 6To prevent the filter drum 5 from vibrating during high-speed rotation, thus affecting the collision between the shot and fasteners, a fixed drive gear 607 and a rotatable guide wheel 605 are respectively installed on the outer wall of the drive rod 602. When the motor drives the drive rod 602 to rotate, the drive gear 607 drives the filter drum 5 to rotate through meshing with the gear ring 606. The rolling of the guide ring 604 and the guide wheel 605 prevents the filter drum 5 from vibrating during rotation. To improve the collision efficiency between the shot and fasteners, the filter drum 5 has a flip-over structure inside the protective frame 2. Guide grooves 610 are opened inside both sides of the protective frame 2. When the drum shot blasting machine is started, the hydraulic telescopic rod 614 is intermittently driven to push the hinge rod 613. Pull, under the hinge of the hinge rod 613, push the push-pull rod 611 to slide along the guide groove 610, thereby causing the protective outer frame 2 to drive the filter roller 5 to rotate intermittently at a certain angle, thereby improving the collision between the shot and the fastener, and thus improving the cleaning efficiency of the fastener. After the roller-type shot blasting machine has finished cleaning the fastener, in order to facilitate the unloading of the fastener, a rotatable unloading rod 608 is inserted through the inside of the filter roller 5, and the motor driving the unloading rod 608 is installed at the middle position of the rear end of the protective outer frame 2. Under the drive of the motor, the unloading rod 608 can drive the unloading impeller 609 to rotate. When it is necessary to unload the cleaned fastener, the front end of the filter roller 5 is tilted to the lowest angle, so that the fastener gradually rolls to the front end. After the unloading impeller 609 rotates, the fastener can be gradually pushed outward, thereby unloading.

[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.
