Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, and in particular relates to a shot blasting machine for pretreatment of metal products. Background Technology

[0002] The metal product coating pretreatment drum shot blasting machine is an automated surface treatment equipment. A drum conveyor system uniformly feeds the workpiece into the shot blasting chamber, where a high-speed shot blaster propels steel shot or ceramic shot onto the metal surface, effectively removing oxide scale, rust, and welding slag, while simultaneously creating a uniform roughness to enhance coating adhesion. Its core structure includes a wear-resistant drum, shot blaster, shot separation and circulation system, and dust removal device. The workflow encompasses feeding, shot blasting, shot recovery, and dust filtration, all intelligently controlled by a PLC or touchscreen. This equipment is widely used in the field of coating pretreatment surface treatment.

[0003] During the surface pretreatment of the metal plate before coating, it is placed on the conveyor roller. The metal plate is moved to the shot blasting mechanism by the conveyor roller. The shot blasting mechanism performs surface treatment. The metal plate is removed by the movement of the roller. Then the metal plate is flipped and enters again from the input end of the roller, thus realizing double-sided shot blasting of the metal plate. In this method, the flipping and handling process requires the use of transfer equipment or manual labor, which is not convenient and efficient.

[0004] To address the aforementioned issues, this application proposes a shot blasting machine for pretreatment of metal products. Utility Model Content

[0005] The purpose of this invention is to provide a shot blasting machine for pretreatment of metal products coating, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a shot blasting machine for pretreatment of metal products, comprising a first conveying mechanism and a second conveying mechanism, and two shot blasting mechanisms mounted on the upper ends of the first and second conveying mechanisms. The first and second conveying mechanisms are parallel and parallel with opposite conveying directions. A detachable support frame is provided between the output ends of the first and second conveying mechanisms. A rectangular frame is rotatably connected to the support frame, which clamps a metal plate through an electric cylinder and a clamping plate. When the metal plate is clamped, the rectangular frame is located in the middle. A driving mechanism is provided between the support frame and the rectangular frame, which can drive the rectangular frame and the clamped metal plate to flip from the first conveying mechanism to the second conveying mechanism. A flipping distance for the rectangular frame is formed between the first conveying mechanism, the second conveying mechanism, and the support frame.

[0008] Furthermore, the support frame is rotatably provided with support rollers to keep the bottom of the metal plate horizontal, and the support rollers are symmetrically arranged at the input ends of the first conveying mechanism and the second conveying mechanism.

[0009] Furthermore, a support plate is fixed to one end of the support frame near the first conveying mechanism and the second conveying mechanism. The support plate is arranged in two sets, which are used for horizontal support of the rectangular frame before and after flipping.

[0010] Furthermore, a connecting plate is fixed to the end of the support plate away from the support frame, and a positioning rib is fixed to the side of the connecting plate. The first conveying mechanism and the second conveying mechanism are both welded and fixed to a connecting seat that inserts into the connecting plate and is supported by the positioning rib at the ends near the support frame.

[0011] Furthermore, the electric cylinder is fixed to the upper end of the rectangular frame, the clamping plate is located inside the rectangular frame and fixed to the output end of the electric cylinder, and the inner bottom surface of the rectangular frame is flush with the bottom of the metal plate when the rectangular frame is not flipped.

[0012] Furthermore, the drive mechanism includes a worm gear fixed concentrically with the rotating shaft of the rectangular frame and a worm that is mounted on the side of the support frame via a bracket and meshes with the worm gear.

[0013] Furthermore, the drive mechanism also includes a motor fixed to the lower end of the support frame by a bracket, and the output end of the motor is connected to the worm gear by a belt drive.

[0014] This utility model has the following beneficial effects:

[0015] This utility model uses a rectangular frame that fits over the middle of a metal plate and is then pressed down by an electric cylinder and clamping plate. Finally, it is flipped under the action of a drive mechanism. The middle pressing and flipping method has a better balance effect and avoids bending and deformation of the metal plate during the flipping process. At the same time, the automatic flipping works in conjunction with the first and second conveying mechanisms, so that the loading and unloading stations are arranged on the same side, making the overall equipment more compact and facilitating loading and unloading operations.

[0016] This invention utilizes support rollers on the support frame to provide support during the flipping of the metal plate, preventing it from tilting and falling, and ensuring stable flipping. At the same time, the support frame and the conveying mechanism can be quickly assembled and disassembled through connecting plates and connecting seats, increasing the flexibility of use.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figures 1-4As shown, this utility model is a shot blasting machine for pre-treatment of metal products, including a first conveying mechanism 1 and a second conveying mechanism 2. Both the first conveying mechanism 1 and the shot blasting mechanism 3 are roller-type conveying mechanisms, meaning that rollers are installed inside a support frame, and synchronization is achieved through chains and sprockets. The sprockets are driven by a motor, thereby realizing the conveying of metal plates. Shot blasting mechanisms 3 are installed on both the first conveying mechanism 1 and the shot blasting mechanism 3. The first conveying mechanism 1 and the second conveying mechanism 2 are parallel and parallel with opposite conveying directions. The specific conveying directions of the two are as follows: Figure 2 As indicated by the arrow, a detachable support frame 4 is provided between the output end of the first conveying mechanism 1 and the output end of the second conveying mechanism 2. A rectangular frame 5 is rotatably connected to the support frame 4, which clamps the metal plate through the cooperation of an electric cylinder 51 and a clamping plate 52. When the metal plate is clamped, the rectangular frame 5 is located in the middle to ensure uniform clamping and avoid deformation of the metal plate when flipping. A drive mechanism 6 is provided between the support frame 4 and the rectangular frame 5 to drive the rectangular frame 5 and the clamped metal plate to flip from the first conveying mechanism 1 to the second conveying mechanism 2. Through the cooperation of the rectangular frame 5 and the drive mechanism 6, the automatic unloading of the first conveying mechanism 1 and the automatic loading of the second conveying mechanism 2 can be realized, replacing manual operation and eliminating the need for transfer, thus improving work efficiency. A flipping distance for the rectangular frame 5 is formed between the first conveying mechanism 1, the second conveying mechanism 2 and the support frame 4 to ensure that the rectangular frame 5 can flip within 180°, and the rectangular frame 5 is in a horizontal state before and after flipping.

[0028] The support frame 4 is rotatably equipped with a support roller 41 to keep the bottom of the metal plate horizontal. The support roller 41 is symmetrically arranged at the input of the first conveying mechanism 1 and the input of the second conveying mechanism 2. The support roller 41 is used to support the metal plate after it is unloaded by the first conveying mechanism 1 and to support it when it is loaded by the second conveying mechanism 2, so as to prevent the metal plate from tilting and falling after it leaves the conveying mechanism.

[0029] Among them, the support frame 4 is fixed with a support plate 42 near the end of the first conveying mechanism 1 and the second conveying mechanism 2. The support plate 42 is set in two sets, which are used for horizontal support of the rectangular frame 5 before and after flipping. The support plate 42 that cooperates with the discharge end of the first conveying mechanism 1 is set as one piece, while the support plate 42 that cooperates with the feed section of the second conveying mechanism 2 is set separately. The separate setting is used to avoid the electric cylinder 51 after it flips.

[0030] Among them, a connecting plate 43 is fixed to the end of the support plate 42 away from the support frame 4, and a positioning rib 431 is fixed to the side of the connecting plate 43. The first conveying mechanism 1 and the second conveying mechanism 2 are both welded and fixed to the end near the support frame 4 with a connecting seat 7 that is inserted into the connecting plate 43 and supported by the positioning rib 431. The connecting plate 43 and the connecting seat 7 are vertically inserted. After the two are inserted, they are positioned by the positioning rib 431. At this time, the bottom support leg of the support frame 4 is in contact with the ground. The stable connection with the two conveying mechanisms can be ensured by the weight of the support frame 4 and its connecting parts.

[0031] Among them, there are at least two electric cylinders 51 and they are fixed at the upper end of the rectangular frame 5 when it is not flipped. The clamping plate 52 is located inside the rectangular frame 5 and is fixed to the output end of the electric cylinder 51. After the electric cylinder 51 pushes the clamping plate 52, the metal plate is clamped inside the rectangular frame 5. When the rectangular frame 5 is not flipped, the bottom surface of the inner side is flush with the bottom of the metal plate. The flush setting can avoid deformation of the metal plate during clamping.

[0032] The drive mechanism 6 includes a worm wheel 61 that is fixed concentrically with the rotation axis of the rectangular frame 5 and a worm 62 that is mounted on the side of the support frame 4 via a bracket and meshes with the worm wheel 61. The cooperation between the worm wheel 61 and the worm 62 can reduce speed, increase torque, and self-lock, ensuring the stable rotation of the rectangular frame 5 and the metal plate.

[0033] The drive mechanism 6 also includes a motor 63 fixed to the lower end of the support frame 4 by a bracket. The output end of the motor 63 is connected to the worm gear 62 by a belt drive 64. The motor 63 is placed at the lower end of the support frame 4 and reliably transmitted through the belt drive 64, making the overall arrangement of the drive mechanism 6 on the support frame 4 more compact.

[0034] Understandably, this utility model uses a rectangular frame, an electric cylinder, and a clamping plate to press the center of the metal plate, and combines this with a drive mechanism to achieve a balanced and stable flipping action, effectively preventing the metal plate from bending and deforming. By arranging the first and second conveying mechanisms on the same side and combining them with an automatic flipping function, the equipment concentrates the loading and unloading stations, significantly improving structural compactness and ease of operation. At the same time, the support frame provides dynamic support and protection during the flipping process through support rollers to prevent the metal plate from tilting. The modular design of its connecting plate and connecting seat enables quick assembly and disassembly, enhancing the adaptability and maintenance efficiency of the equipment.

[0035] A specific application of this embodiment is as follows: the first conveying mechanism 1 and the second conveying mechanism 2 are placed side by side with opposite conveying directions and are both equipped with independent shot blasting mechanisms 3. The same end of the first conveying mechanism 1 and the second conveying mechanism 2 is welded with a connecting seat 7. After the support frame 4 and its upper end connector are assembled, the connecting plate 43 is inserted into the connecting seat 7 from top to bottom. The positioning rib 431 positions the insertion depth. The metal plate is placed on the first conveying mechanism 1 and is polished by the shot blasting mechanism 3 through the conveying of the first conveying mechanism 1. Then it is partially moved to the support roller 41 and passes through the rectangular frame 5. At this time, the electric cylinder 51 drives the clamping plate 52 to move down and press the metal plate. The driving mechanism 6 drives the rectangular frame 5 and the metal plate to flip. The metal plate is flipped onto the second conveying mechanism 2. The electric cylinder 51 drives the clamping plate 52 to loosen. Through the conveying of the second conveying mechanism 2, the metal plate is pulled out from the rectangular frame 5 and polished on the other side under the action of the shot blasting mechanism 3.

[0036] The drive mechanism 6 is used as follows: the output end of the motor 63 drives the worm 62 to rotate through the belt drive 64. The worm 62 meshes with the worm wheel 61 and drives the rectangular frame 5 to rotate. The rectangular frame 5 flips back and forth within 180°, and after each flip, it contacts the support plate 42, so that the rectangular frame 5 remains in a horizontal state.
