Abstract
Description
Technical Field
[0001] This utility model relates to the field of sandblasting equipment technology, specifically to automatic sandblasting equipment. Background Technology
[0002] Sandblasting technology uses compressed air to create a high-speed jet, which propels abrasive materials onto the surface of the workpiece to be treated. This causes changes in the appearance of the workpiece's outer surface. Due to the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface achieves a certain degree of cleanliness and different roughness, thereby improving the mechanical properties of the workpiece surface.
[0003] Currently, sandblasting of products is mostly done manually by workers holding spray guns. This process involves long training periods for workers and results in inconsistent quality. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic spraying device that can transport products to the sandblasting head and control the sandblasting head to swing up and down to fully sandblast the sides of the products.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:
[0006] An automatic sandblasting device includes a sandblasting unit connected to a sandblasting head. The device includes a frame, a conveyor belt within the frame, and a sandblasting head positioned on the side of the conveyor belt on the inner wall of the frame. The frame also includes a rotating device for controlling the rotation of the sandblasting head within a normal plane along the extension direction of the conveyor belt. The sandblasting unit and sandblasting head can utilize existing technology. Its function is to use the conveyor belt to transport products to the sandblasting head, and to slowly transport the products forward by coordinating the up-and-down oscillation of the sandblasting head; the rotating device enables the sandblasting head to oscillate up and down, thereby performing comprehensive sandblasting treatment on the products on the conveyor belt from top to bottom.
[0007] Furthermore, the rotating device includes a collar sleeved on the outer wall of the sandblasting head, and a motor is connected to the collar. The sandblasting head and the collar are coaxially arranged. Its function is that, through the motor on the collar, the motor drives the collar to rotate around the output shaft of the motor, thereby causing the sandblasting head inside the collar to swing up and down.
[0008] Furthermore, the output shaft of the motor is perpendicular to the extension direction of the sandblasting head and parallel to the extension direction of the conveyor belt. The motor's output shaft is a rotating shaft, which is existing technology and will not be elaborated upon. Its function is that, through the design of the motor's output shaft direction, the sandblasting head can rotate within the normal plane of the conveyor belt's extension direction.
[0009] Furthermore, the frame is equipped with a support plate for mounting the motor, and a hydraulic cylinder is connected inside the frame, with the output shaft of the hydraulic cylinder connected to the support plate. Its function is to allow the sandblasting head to move up and down via the support plate and hydraulic cylinder, thus accommodating products with a wider height range and ensuring good sandblasting results when sandblasting higher or lower parts of the product.
[0010] Furthermore, the output shaft of the hydraulic cylinder is perpendicular to the top surface of the conveyor belt. Its function is to allow the sandblasting head to move vertically up and down by designing the direction of the hydraulic cylinder's output shaft.
[0011] Furthermore, the frame is equipped with a blocking device to block the top surface of the conveyor belt. The height of the blocking device is between the bottom end of the sandblasting head and the top end of the conveyor belt. Its function is to prevent the abrasive material sprayed from the sandblasting head from directly hitting the conveyor belt and thus damaging it.
[0012] Furthermore, the blocking device includes a guide rail and a baffle extending in a direction perpendicular to the side wall of the frame. The baffle is positioned above the guide rail, and the bottom surface shape of the baffle matches the top surface shape of the guide rail. Its function is to allow the baffle to move towards and away from the conveyor belt, thereby accommodating products of different widths, through the arrangement of the guide rail and the baffle.
[0013] Furthermore, the guide rail is provided with T-shaped guide portions at both ends in the conveyor belt conveying direction, and the baffle is provided with sleeve grooves with the same internal shape and size as the guide plate at both ends in the conveyor belt conveying direction. The function of these guide portions and sleeve grooves is to prevent the baffle from swaying back and forth or up and down on the guide rail.
[0014] Furthermore, the sandblasting device includes a sand storage cylinder for storing the abrasive material and an air compressor for outputting high-pressure gas. A sandblasting pipe connects the sand storage cylinder to the sandblasting head, and an air supply pipe connects the sandblasting pipe to the air compressor. This is a conventional design for sandblasting devices and will not be elaborated further.
[0015] Furthermore, the frame is equipped with a sand storage cylinder on each of the left and right sides in the conveyor belt's conveying direction, and an air compressor is located at the top of the frame. There are two air supply pipes, and a three-way valve connects the two air supply pipes to the air compressor. The three-way valve itself uses existing technology and will not be described in detail. Its function is to control the high-pressure gas output from the air compressor to be directed to either one of the air supply pipes, or simultaneously to both air supply pipes.
[0016] The beneficial effects of this utility model are:
[0017] 1. The conveyor belt can transport products to the sandblasting head and slowly move the products forward in coordination with the up-and-down swing of the sandblasting head; the rotating device can make the sandblasting head swing up and down, so as to perform comprehensive sandblasting treatment on the products on the conveyor belt from top to bottom.
[0018] 2. By setting the motor of the collar, the drive motor drives the collar to rotate around the output shaft of the motor, thereby causing the sandblasting head inside the collar to swing up and down;
[0019] 3. With the support plate and hydraulic cylinder, the sandblasting head can be moved up and down, thus adapting to products with a wider height range, and achieving good sandblasting results when sandblasting higher or lower parts of the product. Attached Figure Description

[0026] Example 1
[0027] An automatic sandblasting device, such as Figure 1 As shown, the device includes a sandblasting apparatus connected to a sandblasting head 1. It includes a frame 2, within which a conveyor belt 3 is installed. The sandblasting head 1 is mounted on the inner wall of the frame 2, positioned on the side of the conveyor belt 3. The frame 2 also includes a rotating device for controlling the rotation of the sandblasting head 1 within the normal plane of the conveyor belt 3's extension direction. The sandblasting apparatus and sandblasting head 1 can utilize existing technology. Its function is to transport the product to the sandblasting head 1 via the conveyor belt 3, and to slowly transport the product forward by coordinating the up-and-down oscillation of the sandblasting head 1; the rotating device enables the sandblasting head 1 to oscillate up and down, thereby performing comprehensive sandblasting treatment on the product on the conveyor belt 3 from top to bottom.
[0028] Specifically, such as Figure 1 As shown, the rotating device includes a collar 4 sleeved on the outer wall of the sandblasting head 1, and a motor 5 connected to the collar 4. The sandblasting head 1 and the collar 4 are coaxially arranged. Its function is that, through the arrangement of the motor 5 on the collar 4, the motor 5 drives the collar 4 to rotate around the output shaft of the motor 5, thereby causing the sandblasting head 1 inside the collar 4 to swing up and down.
[0029] Specifically, such as Figure 1 As shown, the output shaft of the motor 5 is perpendicular to the extension direction of the sandblasting head 1 and parallel to the extension direction of the conveyor belt 3. The output shaft of the motor 5 is a rotating shaft, which is existing technology and will not be elaborated further. Its function is that, through the design of the direction of the output shaft of the motor 5, the sandblasting head 1 can rotate within the normal plane of the extension direction of the conveyor belt 3.
[0030] Specifically, such as Figure 1 As shown, the frame 2 is equipped with a support plate 6 for mounting the motor 5, and a hydraulic cylinder 7 is connected inside the frame 2. The output shaft of the hydraulic cylinder 7 is connected to the support plate 6. Its function is that, through the arrangement of the support plate 6 and the hydraulic cylinder 7, the sandblasting head 1 can be moved up and down, thereby adapting to products with a wider height range, so that a good sandblasting effect can still be achieved when sandblasting higher or lower parts of the product.
[0031] Specifically, such as Figure 1As shown, the output shaft of the hydraulic cylinder 7 is perpendicular to the top surface of the conveyor belt 3. Its function is to drive the sandblasting head 1 to move vertically up and down by designing the direction of the output shaft of the hydraulic cylinder 7.
[0032] Specifically, such as Figure 1 As shown, the frame 2 is equipped with a blocking device to block the top surface of the conveyor belt 3. The height of the blocking device is between the bottom end of the sandblasting head 1 and the top end of the conveyor belt 3. Its function is to prevent the aerosol sprayed from the sandblasting head 1 from directly spraying onto the conveyor belt 3, thereby preventing damage to the conveyor belt 3.
[0033] Specifically, such as Figure 1 As shown, the blocking device includes a guide rail 8 and a baffle 9 extending in a direction perpendicular to the side wall of the frame 2. The baffle 9 is located above the guide rail 8, and the bottom shape of the baffle 9 matches the top shape of the guide rail 8. Its function is that, through the arrangement of the guide rail 8 and the baffle 9, the baffle 9 can move towards and away from the conveyor belt 3, thereby accommodating products of different widths.
[0034] Specifically, such as Figure 2 As shown, the guide rail 8 has T-shaped guide portions 10 at both ends of the conveyor belt 3 in the conveying direction, and the baffle 9 has sleeve grooves 11 at both ends of the conveyor belt 3 in the conveying direction, with the same internal shape and size as the guide plate. Their function is to prevent the baffle 9 from swaying back and forth or up and down on the guide rail 8 through the arrangement of the guide portions 10 and sleeve grooves 11.
[0035] Specifically, such as Figure 1 As shown, the sandblasting device includes a sand storage cylinder 12 for storing the abrasive material and an air compressor 13 for outputting high-pressure gas. A sandblasting pipe 14 connects the sand storage cylinder 12 and the sandblasting head 1, and an air supply pipe 15 connects the sandblasting pipe 14 and the air compressor 13. This is a conventional design for a sandblasting device and will not be described in detail.
[0036] Specifically, such as Figure 1 As shown, the frame 2 has a sand storage cylinder 12 on each of the left and right sides in the conveying direction of the conveyor belt 3. An air compressor 13 is located on the top of the frame 2. There are two air supply pipes 15, and a three-way valve 16 connects the two air supply pipes 15 to the air compressor 13. The three-way valve 16 itself uses existing technology and will not be described in detail. Its function is to control the high-pressure gas output from the air compressor 13 to be blown onto either air supply pipe 15, or simultaneously onto both air supply pipes 15.
[0037] The working principle of this embodiment is explained as follows: First, the product is placed on the conveyor belt 3, and the baffle 9 is moved towards the product, blocking the conveyor belt 3 near the product. The conveyor belt 3 transports the product to the location of the sandblasting head 1. Then, the sandblasting device and air compressor 13 are started, causing the abrasive material to be sprayed from the sandblasting head 1 (this step is existing technology, and how it is implemented will not be described in detail). The motor 5 is started, controlling the sandblasting head 1 to swing up and down, thereby sandblasting the side of the product. When the sandblasting effect is poor at the higher parts of the product, the hydraulic cylinder 7 is driven to lift the support plate 6; when the sandblasting effect is poor at the lower parts of the product, the hydraulic cylinder 7 is driven to lower the support plate 6. When the sandblasting of the currently sandblasted section is completed or during sandblasting, the conveyor belt 3 slowly moves the product forward, so that the side of the product is completely sandblasted.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
