Description

Technical Field

[0001] This utility model relates to the field of plate sandblasting pretreatment technology, and in particular to an inclined integrated line sandblasting device. Background Technology

[0002] In the machinery manufacturing industry, surface pretreatment of sheet metal is an indispensable step. Sandblasting removes surface oxide scale and grease and creates a roughness that meets standards, laying the foundation for subsequent processes such as leveling, painting, and cutting. Therefore, the performance of sheet metal sandblasting pretreatment equipment directly affects product quality and production efficiency.

[0003] In existing technologies, sandblasting pretreatment of sheet metal mostly uses horizontal sandblasting machines or inclined sandblasting machines, but both are single-sheet sandblasting methods. Horizontal sandblasting machines have problems such as excessive sand accumulation and high energy consumption, while inclined sandblasting machines have slightly lower energy consumption but still have low production efficiency. Both methods require a large number of operators, resulting in high labor intensity and labor costs. At the same time, the discrete single-machine single-roll processing mode is difficult to adapt to the needs of automated production, leading to limited production efficiency and insufficient product quality stability. These defects seriously affect product quality and economic benefits. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an inclined integrated sand making line device to realize automated continuous production, which has the effects of improving production efficiency, reducing energy consumption and saving labor costs.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] An inclined integrated sandblasting device includes a feeding tensioning and flattening device, a feeding tilting and positioning device, multiple feeding rollers, multiple sets of inclined sandblasting devices, multiple discharge rollers, a discharge tilting and positioning device, and a discharge tensioning and flattening device, which are arranged in series along the steel coil medium processing flow.

[0007] Multiple feed rollers are disposed at the inlet end of the conveying channel, and multiple discharge rollers are disposed at the outlet end of the conveying channel;

[0008] The inclining positioning device, the multiple sets of inclining sand-blasting devices, and the inclining positioning device have the same inclining angle, and together with the multiple inclining rollers and multiple outcrying rollers at both ends of the conveying channel, they form an inclining conveying channel for the steel coil medium.

[0009] Through the above technical solution, as the steel coil medium passes through each device in sequence, it can form a continuous inclined channel by utilizing the consistent inclination angle of each inclined device and the inclined sandblasting device, achieving a smooth transition from horizontal to inclined and back to horizontal. At the same time, the whole material conveying of the steel coil medium reduces the frequent start and stop of traditional single sheet feeding, avoiding sandblasting blind spots caused by splicing gaps. Simultaneously, the sandblasting process is completed in the inclined sandblasting device, effectively improving the continuity and integration of steel coil processing, and ensuring the stability and uniformity of the sandblasting process.

[0010] As a further technical solution of this utility model: the inclined sand-blasting device includes at least two sets.

[0011] Through the above technical solution, the setting of multiple sets of inclined sandblasting devices can perform multiple continuous sandblasting processes on the steel coil medium, avoiding the problems of insufficient and uneven sandblasting by a single set of devices, significantly improving the sandblasting quality and processing efficiency of the steel coil surface, and meeting the requirements for the surface treatment accuracy of steel coils under different working conditions.

[0012] As a further technical solution of this utility model: each of the multiple sets of inclined sand-blasting devices includes a sand-blasting chamber, a shot blaster, a shot distributor, a sand-falling hopper, and a hoist;

[0013] The discharge port of the sand-blasting chamber is connected to the inlet of the sand-falling hopper, the discharge port of the sand-falling hopper is connected to the elevator, the elevator is connected to the shot distributor, the shot distributor is connected to the shot blaster, and the shot blaster is installed at the upper and lower ends of the sand-blasting chamber.

[0014] Through the above technical solution, the shot blaster, shot distributor, sand drop hopper and lifting mechanism in the inclined sand blasting device form a complete sand shot circulation system, which enables the sand shot to be efficiently recovered and reused, reducing the consumption cost of sand shot. At the same time, the shot blasters at the upper and lower ends can simultaneously sand blast the upper and lower surfaces of the steel coil medium, ensuring the uniformity and comprehensiveness of sand blasting on the steel coil surface.

[0015] As a further technical solution of this utility model: both the feeding tilt positioning device and the discharging tilt positioning device include a first base that is tilted, and a first archway is vertically fixed on the first base.

[0016] The lower part of the first archway is fixedly installed with a lower clamping roller, and the upper part is slidably connected with an upper clamping roller.

[0017] The upper pinch roller is located directly above the lower pinch roller. Each end of the upper pinch roller is equipped with a first hydraulic cylinder, and the distance between the upper pinch roller and the lower pinch roller is adjusted by the first hydraulic cylinder.

[0018] Through the above technical solution, the feeding tilt positioning device and the discharging tilt positioning device achieve the tilt angle fixation by means of the tilt fixed base. The upper and lower clamping rollers adjust the spacing under the drive of the hydraulic cylinder. It can not only adapt to steel coil media of different thicknesses, but also achieve the tilt positioning of the plate through forced clamping. This ensures that the steel coil achieves a smooth state transition when entering and leaving the tilt channel, and reduces the stress deformation and damage of the steel coil during the transition process.

[0019] As a further technical solution of this utility model: both of the first hydraulic cylinders are equipped with pressure regulating devices.

[0020] Through the above technical solution, the pressure adjustment devices set in the two hydraulic cylinders can adjust the pressure at both ends of the upper pinch roller according to the width and thickness of the steel coil medium, ensuring uniform pinching force and preventing the steel coil from deviating or experiencing uneven force during inclined positioning and conveying, thereby further improving the positioning accuracy and conveying stability.

[0021] As a further technical solution of this utility model: both the feeding tensioning and flattening device and the discharging tensioning and flattening device include a horizontally arranged second base, on which a second archway is installed.

[0022] The lower part of the second archway is fixedly installed with a downward pressure roller, and the upper part of the second archway is slidably connected with an upward pressure roller.

[0023] The upper pressure roller is driven to rise and fall by a second hydraulic cylinder to tighten and flatten the steel coil medium.

[0024] Through the above technical solution, the upper pressure roller in the feeding and discharging tensioning and flattening device can be raised and lowered under the drive of the second hydraulic cylinder. Together with the lower pressure roller, it can tension and flatten the steel coil medium, which can eliminate the wrinkles and deformation of the steel coil, ensure that the steel coil enters the inclined sandblasting channel in a flat state and is output after processing, and provide a good foundation for subsequent sandblasting and other processes, thus improving the overall product quality.

[0025] In summary, this utility model has at least one of the following beneficial technical effects:

[0026] 1. This utility model discloses an inclined integrated line sandblasting device, which forms a continuous steel coil conveying channel by connecting various devices in series, realizing the integrated continuous processing of steel coil media from horizontal flattening, inclined sandblasting to horizontal return, breaking through the traditional discrete processing mode of single machine single coil sandblasting.

[0027] 2. This utility model discloses an inclined integrated sandblasting device, which realizes continuous sandblasting of steel coil media through the series arrangement of multiple inclined sandblasting devices, replacing the original intermittent processing of single machine and single coil, improving production efficiency and adapting to the operation of automated production lines, thereby improving economic benefits.

[0028] 3. This utility model discloses an inclined integrated sandblasting device, which, through the coordinated action of the inclined first base of the feeding inclined positioning device and the discharging inclined positioning device, the hydraulically driven upper clamping roller and the pressure adjustment device, realizes the clamping and angle guidance of the steel coil when switching between horizontal and inclined states, ensuring that the steel coil smoothly enters or leaves the inclined sandblasting channel, and avoiding the conveying jamming and surface scratches caused by rigid clamping or angle deviation in traditional devices.

[0038] Example 1:

[0039] Reference Figure 1 and Figure 2 The present invention discloses an inclined integrated sandblasting device, which includes a feeding tensioning and flattening device 2, a feeding tilting and positioning device 3, multiple feeding rollers 4, multiple sets of inclined sandblasting devices 5, multiple discharge rollers 6, a discharge tilting and positioning device 7, and a discharge tensioning and flattening device 8 arranged in series along the processing flow of the steel coil medium 1. Through the coordinated operation of the above components, a continuous processing link is constructed for the steel coil medium 1 from the input to the output of the finished product.

[0040] Multiple feed rollers 4 are arranged at intervals at the inlet end of the conveying channel 19. The axes of each feed roller 4 are parallel to each other and perpendicular to the conveying direction of the steel coil medium 1. The supporting surface formed by them is at the same tilt angle as the output end of the feed tilting positioning device 3. Multiple discharge rollers 6 are arranged at intervals at the outlet end of the conveying channel 19. The supporting surface formed by them is at the same tilt angle as the input end of the discharge tilting positioning device 7.

[0041] Reference Figure 1 The inclination angles of the feeding tilt positioning device 3, the multiple sets of tilt sand-blasting devices 5, and the discharging tilt positioning device 7 are consistent (preferably 24° to 35°). After connecting with the supporting surfaces of the feeding roller 4 and the discharging roller 6, they together form a continuous tilting conveying channel. The consistency of the tilt angle of this channel ensures that the steel coil medium 1 remains stable during the conveying process, avoiding uneven sand-blasting or conveying jams caused by angle changes.

[0042] Reference Figure 1 and Figure 2 The multiple sets of inclined sandblasting devices 5 include at least two sets, and in practical applications, more sets can be connected in series as needed (e.g., 3, 4, 5, 7, or 8 sets). The more inclined sandblasting devices 5 connected in series, the higher the production efficiency. (Refer to...) Figure 3 Each set of inclined sand-blasting devices 5 consists of a sand-blasting chamber 51, a shot blaster 52, a shot distributor 53, a sand drop hopper 54, and an elevator 55. After being blasted by the shot blaster 52, the sand shot falls to the bottom of the sand-blasting chamber 51, is received by the sand drop hopper 54, and is sent back to the elevator 55. The elevator 55 transports the sand shot to the shot distributor 53, which supplies shot to the shot blaster 52. The shot blaster 52 is symmetrically installed at the upper and lower ends of the sand-blasting chamber 51 to achieve double-sided sand-blasting treatment of the surface of the steel coil medium 1. Through the linkage of the sand drop hopper 54, the elevator 55, and the shot distributor 53, the sand shot is recycled.

[0043] Reference Figure 4 The feeding tilt positioning device 3 and the discharging tilt positioning device 7 have the same structure, both including an inclined first base 9, on which a first archway 10 is vertically fixed to form a support frame; a lower clamping roller 12 is fixedly installed at the lower part of the first archway 10, and an upper clamping roller 11 is slidably connected at the upper part, forming a clamping and conveying component; both ends of the upper clamping roller 11 are respectively provided with a first hydraulic cylinder 13, and the distance between the upper and lower clamping rollers 12 is adjusted by the first hydraulic cylinder 13, and each of the two first hydraulic cylinders 13 is provided with a pressure regulating device. The feeding tilt positioning device 3 and the discharging tilt positioning device 7 establish an angle reference by tilting the first base 9, and the upper clamping roller 11 and the lower clamping roller 12, which are hydraulically driven by the first hydraulic cylinders 13, are adapted to steel coil media 1 of different thicknesses. With the help of pressure regulation, the clamping force is ensured to be uniform, thereby realizing the smooth transition of the steel coil media 1 from horizontal to inclined and from inclined to horizontal, respectively, avoiding jamming and deviation during the transition.

[0044] Reference Figure 5 The feeding tensioning and flattening device 2 and the discharging tensioning and flattening device 8 have the same structure, both including a horizontally set second base 14, on which a second archway 15 is installed. The lower part of the second archway 15 is fixedly installed with a lower flattening roller 17, and the upper part is slidably connected with an upper flattening roller 16. The upper flattening roller 16 is driven to lift and lower by a second hydraulic cylinder 18. The feeding tensioning and flattening device 2 uses the cooperation of the upper flattening roller 16 and the lower flattening roller 17 to press and flatten the steel coil medium 1, eliminating wrinkles and deformation, and laying a flat foundation for subsequent tilting and positioning treatment. The discharging tensioning and flattening device 8 uses the same flattening structure to force the steel coil medium 1 back to flatten after sanding, ensuring that it is finally output in a flat state.

[0045] The working process of this utility model is as follows:

[0046] Step 1: Feeding end tensioning and flattening. The steel coil medium 1 enters the feeding tensioning and flattening device 2. The second hydraulic cylinder 18 drives the upper flattening roller 16 to descend, which cooperates with the lower flattening roller 17 to apply pressure to the steel coil medium 1, eliminating surface wrinkles and local deformation, and outputting a horizontal and flat steel coil medium 1.

[0047] Step 2: Feeding Side State Transition. The horizontal steel coil medium 1 enters the feeding tilting positioning device 3. The tilted first base 9 provides a fixed angle reference. The first hydraulic cylinder 13 drives the upper clamping roller 11 to press down, working together with the lower clamping roller 12 to clamp the steel coil medium 1. The pressure adjustment devices at both ends balance the clamping force to prevent the steel coil medium 1 from deviating, thus achieving a stable transition of the steel coil medium 1 from a horizontal state to an tilted state.

[0048] Step 3: Continuous sandblasting in the inclined channel. The inclined steel coil medium 1 is conveyed to the inclined sandblasting device 5 via the feed roller 4. Multiple sets of inclined sandblasting devices 5 sequentially perform continuous sandblasting on the steel coil medium 1. Inside the sandblasting chamber 51, the upper and lower shot blasters 52 simultaneously spray sand shot onto both sides of the steel coil medium 1 to complete the surface treatment. After sandblasting, the sand shot falls into the sand drop hopper 54 for collection, and is then conveyed to the shot distributor 53 via the elevator 55. The shot distributor 53 then feeds shot to the shot blasters 52, forming a closed-loop sand shot circulation to improve the utilization rate of consumables.

[0049] Step 4: Returning the discharge side to the correct position. The steel coil medium 1 after sandblasting is conveyed to the discharge tilting positioning device 7 via the discharge roller 6. With the help of the first base 9, upper clamping roller 11, lower clamping roller 12 and first hydraulic cylinder 13, which are symmetrical to the feeding tilting positioning device 3, the steel coil medium 1 is reversed from the tilted state to the horizontal state, ensuring the stability of the discharge state.

[0050] Step 5: Exit end tensioning and flattening. The horizontally positioned steel coil medium 1 enters the outlet tensioning and flattening device 8. The upper flattening roller 16 and the lower flattening roller 17 work together again to apply pressure to the steel coil medium 1, eliminating the slight deformation during the sandblasting process, and finally outputting a finished steel coil medium 1 with a flat surface and qualified sandblasting.

[0051] The implementation principle of this utility model is as follows: Using a whole steel coil medium 1 as the processing substrate, its continuous operation is adapted to a "horizontal-inclined-horizontal" coherent conveying and processing channel. Compared to single sheets, this reduces frequent feeding stops and manual intervention, and avoids uneven splicing. The feeding tensioning and flattening device 2 ensures that the steel coil medium 1 is horizontal and flat when it enters, laying the foundation for subsequent processing; the discharging tensioning and flattening device 8 ensures that the steel coil medium 1 is horizontal and flat when it leaves, ensuring output quality; the feeding tilting positioning device 3 achieves a stable transition of the steel coil medium 1 from horizontal to inclined, and the discharging tilting positioning device 7 completes the return to the horizontal state, both avoiding jamming and deviation during the transition; multiple sets of tilting sandblasting devices 5 form a continuous sandblasting space, simultaneously sandblasting and recycling sand pellets to reduce energy consumption; all devices are connected into a complete link through the feeding roller 4 and the discharging roller 6, enabling the steel coil medium 1 to simultaneously complete flattening, state transition, sandblasting, and return to flattening during continuous conveying, ultimately achieving automated continuous production and solving the problems of low efficiency, high energy consumption, and high labor requirements of traditional single-machine processing.

[0052] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
