Description

Technical Field

[0001] The invention relates to the technical field of embossing roller processing, in particular to a sandblasting device for reprocessing an embossing roller. Background Art

[0002] The sandblasting process can use high-speed sand flow to efficiently and thoroughly remove rust, impurities, residual oil stains from the surface of the rough roller. After being used by customers, the embossing roller will usually fail within three months or damage the roller surface by pressing foreign objects, and will eventually be returned to the factory for repair. The repair process involves sandblasting of the embossing roller, which is a process technology that uses high-speed sand flow to clean or roughen the roller surface. During the sandblasting process, compressed air is used as power to form a high-speed jet beam in the sandblasting machine, and the spray material is sprayed onto the roller surface at high speed. The appearance and shape of the roller after sandblasting will be changed, and the surface mechanical properties will change to a certain extent.

[0003] Chinese patent CN210997844U discloses an automatic copper roller grinding and sandblasting device, which includes a frame, a mounting plate, a movable seat, a grinding mechanism and a sandblasting mechanism. The mounting plate is fixed on the frame, and the movable seat can be moved horizontally left and right through the movable mechanism and is set on the mounting plate. The grinding mechanism includes a first fixed seat, a first lifting unit, a first motor and a grinding wheel. The first fixed seat is fixed on the movable seat, the first lifting unit is set on the first fixed seat, and is used to drive the first motor to move up and down in a straight line. The grinding wheel is coaxially fixed on the output shaft of the first motor. The sandblasting mechanism includes a second fixed seat, a second lifting unit, a support plate and a sandblasting head. The second fixed seat is fixed on the movable seat and is located on one side of the first fixed seat. The second lifting unit is fixed on the second fixed seat. The sandblasting head is mounted on the support plate and is connected to the external sandblasting tank.

[0004] However, during actual use, the inventors found that during the surface treatment of the embossing roller, the sandblasting equipment was performing sandblasting on the spraying surface. However, due to the effect of gravity, the distribution of the spray material within the spraying surface was uneven, resulting in different cleaning forces on the spraying surface and the embossing roller surface was not clean and smooth.

[0028] Beneficial effects of the present invention:

[0029] (1) The spraying mechanism and the clamping unit provided in the present invention cooperate with each other. On the one hand, the spraying material can be adjusted to be arranged linearly first, and then the linearly arranged spraying material can be sprayed on the outer surface of the embossing roller along a straight line path. The spraying method is converted from the spraying surface to the spraying line, which ensures the uniform distribution of the spraying material and improves the cleaning effect of the embossing roller surface. The embossing roller surface is cleaned more smoothly. On the other hand, the disordered spraying material can be automatically arranged in an orderly linear distribution. The linear arrangement is more uniform, and the spraying material distributed along the straight line is less likely to be missing or broken, thereby ensuring the uniform distribution of the spraying material on the straight line.

[0030] (2) The present invention cooperates with the weight measuring unit and the material distribution unit. On the one hand, the amount of recycled material each time can be accurately measured, and the material replenishment in the replenishing bin can be accurately replenished, thereby ensuring the dynamic balance between the amount of sprayed material and the amount of recycled material, and achieving the effect of continuous circulation of the sprayed material and recycled material; on the other hand, the recycled material entering the mixing bin can be oscillated and evenly mixed, so that the recycled material falls evenly onto the guide plate, which is convenient for accurate measurement of the recycled material each time;

[0031] (3) The present invention provides an adjustment portion so that when the spray mechanism is stretched or compressed within a limited translation range, the bellows structure will not cause deformation of pipe one, pipe two, and pipe three while ensuring that the distance between the outer end of the nozzle assembly and the embossing roller is consistent, thereby improving the service life of the pipes. Combined with the connection between the embedded pipe and the pipe, it is ensured that during the deformation of the bellows structure, the spray material or airflow passing through the connection will not change in cross-sectional area at the connection, that is, the cross-sectional area passing through the connection is always consistent, thereby ensuring the smoothness of the flow of the material or airflow at the connection, and achieving the consistency of the spray amount of the spray material at different horizontal positions on the roller surface, thereby improving the spraying effect.

[0032] In summary, the present invention has the advantages of being environmentally friendly, green and sustainable. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0055] Example 1

[0056] like Figures 1-19 As shown, a sandblasting device for embossing roller reprocessing includes a frame 1 and a clamping unit 2 mounted on the frame 1 along the length direction. The embossing roller 100 lies horizontally on the frame 1 and is fixedly clamped at both ends by the clamping unit 2. The device also includes a spray mixing mechanism 5 provided on one side of the embossing roller 100 and a spray mechanism 3 connected to the spray mixing mechanism 5 and used to spray the spray material onto the surface of the embossing roller.

[0057] The nozzle assembly 31 of the spray mechanism 3 first adjusts the spray material 103 to be arranged linearly, and then sprays the linearly arranged spray material as a whole laterally along a straight path onto the outer surface of the embossing roller 100, and the excess material 101 is promptly recovered through the negative pressure mechanism 4 connected to the nozzle assembly 31. The nozzle assembly 31 intermittently temporarily stores the recovered material, and the recovered material is transferred to the spray mixing mechanism 5 for waste treatment, and a certain amount of new material is added as needed for mixing, and the mixed material is again passed into the spray mechanism 3 for cyclic spraying and conveying.

[0058] It should be noted that, at present, the applicant has taken limited measures to prevent damage to the roller surface during the maintenance process:

[0059] 1. The embossing rollers do not directly contact the ground. The embossing rollers in the lathe and grinder areas are placed on wooden mats.

[0060] 2. After the grinding process is completed, wrap it with plastic wrap and place it on a horse stool;

[0061] 3. After the polishing bed is processed, it must be packed in softened packaging bags to ensure that it will not be damaged;

[0062] 4. Take consistent measures for embossing completion and polishing;

[0063] 5. After spraying, brush oil, pack in softened packaging bags, and then pack in wooden boxes for electroplating;

[0064] 6. After electroplating, the roller surface is hardened and scratches by ordinary hard objects will not affect the surface quality. So far, there has been no problem of damaging the roller surface after electroplating is completed.

[0065] During the above process, if the roller surface is damaged, even if it is a very small defect, it is necessary to return to the lathe and start over.

[0066] Based on the above working conditions, in the present application, it is not convenient to set an outer shell outside the frame 1 to cover the spraying mechanism 3 during the spraying process of the embossing roller to avoid unnecessary wear and friction during the disassembly and installation process. The open space has sufficient manual handling space and is not easy to bump into. However, it is precisely because of this that the spraying mechanism 3 will cause the sprayed material to overflow the workshop during the spraying operation, so the sprayed material needs to be recovered.

[0067] It is worth mentioning that the spraying mechanism 3 and the negative pressure mechanism 4 are integrated into one body, and a special pipeline structure is used to timely absorb and recover the sprayed material, so that the sprayed material and the recovered material form an orderly and stable transmission direction, thereby preventing the spray material from splashing to other positions of the embossing roller 100, causing damage to the embossing roller 100 and further causing environmental pollution in the workshop.

[0068] In this embodiment, by cooperating with the provided spraying mechanism 3 and the clamping unit 2, on the one hand, the spraying material can be adjusted to be arranged linearly first, and then the linearly arranged spraying material can be sprayed as a whole laterally along a straight path on the outer surface of the embossing roller, and the spraying method is converted from the spraying surface to the spraying line, thereby ensuring uniform distribution of the spraying material, improving the cleaning effect of the embossing roller surface, and making the embossing roller surface cleaner and smoother; on the other hand, the disordered spraying material can be automatically arranged in an orderly manner into a straight line distribution, the linear arrangement is more uniform, and the spraying material distributed along the straight line is not prone to missing or broken lines, thereby ensuring that the spraying material is evenly distributed on the straight line.

[0069] In detail, first, the nozzle assembly 31 of the spray mechanism 3 adjusts the spray material 103 to be arranged linearly, and then sprays the linearly arranged spray material as a whole laterally along a straight path onto the outer surface of the embossing roller 100, and performs surface treatment on it; then, when the spraying work is in progress, the negative pressure mechanism 4 connected to the nozzle assembly 31 absorbs the excess material 101 in time; the absorbed material is transferred to the spray mixing mechanism 5, and the fine dust and the fine material generated by the destruction pass through the filter 55 and enter the impurity removal bin 53 for collection; then, the absorbed material is transferred to the spray mixing mechanism 5 for waste treatment and then mixed with part of the new material 102, and the mixed material 103 is passed into the spray mechanism 3 again for cyclic spraying.

[0070] Further, if Figure 3-Figure 5 As shown, the nozzle assembly 31 includes an outer cylinder 311, a partition 312 integrally provided inside the outer cylinder 311 and inclined upward near the outer end portion, a plurality of material receiving portions 313 provided below the partition 312 and extending outward in a stepped manner in the vertical direction, a brush portion 314 provided in the circumferential direction of the end of the outer cylinder 311, a material arrangement unit 315 provided inside the partition 312 and used to adjust the linear arrangement of the sprayed materials, and a temporary storage unit 316 provided below the partition 312;

[0071] The upper portion of the partition 312 and the outer cylinder 311 form a spraying channel 317 .

[0072] It is worth mentioning that in this application, by setting up the brush part 314, when the spraying process is in progress, on the one hand, the spraying material is regionally limited so that the excess material can be fully absorbed in a small range. At the same time, the brush part 314 cleans the surface of the embossing roller during the rotation process, and collects the excess spraying material remaining on the roller surface, thereby improving the recovery rate and preventing the spraying material remaining on the roller surface from affecting the next spraying work.

[0073] In addition, the material receiving portion 313 with a multi-step structure can buffer the falling sprayed materials so that they fall into the temporary storage chamber 3161 in an orderly manner.

[0074] Further, if Figure 4-Figure 9 As shown, the material arrangement unit 315 includes an arc-shaped material arrangement channel 3151 opened in the partition 312 and whose outlet end is connected to the injection channel 317, a strip plate 3152 embedded and slidably arranged at the outlet end of the arc-shaped material arrangement channel 3151, a plurality of groups of rake teeth 3153 arranged on one side of the strip plate 3152 and whose lengths decrease in sequence from the middle to both sides, a first driving cavity 3154 opened in the partition 312, an L-shaped connecting plate 3155 arranged on the other side of the strip plate 3152 and extending to the inside of the first driving cavity 3154, and an L-shaped connecting plate 3155 arranged in the first driving cavity 3154 through the rotation of the shaft and used to drive the strip plate 3152 with the rake teeth 3153 along the outer circular wall of the arc-shaped material arrangement channel 3151 to move forward. A first eccentric wheel 3156 that moves horizontally, a first driving member 3157 that is arranged inside the first driving chamber 3154 and is used to drive the first eccentric wheel 3156, a first annular limiting groove opened on the peripheral side of the first eccentric wheel 3156, a first limiting block that is arranged on the side of the L-shaped connecting plate 3155 and slides with the inner wall of the first annular limiting groove, a feeding port 3158 opened at one end away from the port of the outer cylinder 311 and located at the inlet end of the arc-shaped material channel 3151, an air pressure port 3159 opened at one end away from the port of the outer cylinder 311 and located at the inlet end of the injection channel 317, and a guide sinking portion 31591 opened at the inlet end of the injection channel 317 and used to disperse the airflow of the air pressure port 3159.

[0075] It is worth mentioning that the material entering the arc-shaped material channel 3151 from the material delivery port 3158 will continue to move in a circular motion along the outer circular wall of the arc-shaped material channel 3151 due to the centrifugal effect.

[0076] It is also worth mentioning that there are several groups of rake teeth 3153 whose lengths decrease in sequence from the middle to the sides, and the gap between two adjacent rake teeth 3153 can just accommodate a spray material to pass through. When the rake teeth 3153 move back and forth horizontally at the same time, the rake teeth 3153 near the middle position will push the material entering the arc-shaped material channel 3151 from the feed port 3158 to both sides. As the lengths of the rake teeth 3153 on both sides decrease, the material gradually spreads to both sides and falls into the gap between two adjacent rake teeth 3153, so that the material is evenly arranged on the same straight line.

[0077] It should be noted that the guide sinking portion 31591 can diffuse the airflow entering the spray channel 317 from the air pressure port 3159, ensuring that the air pressure in the spray channel 317 is relatively stable, avoiding the airflow gathering and blowing away the spray material arranged in a straight line in the spray channel 317, so that the material is evenly arranged on the same straight line.

[0078] In this embodiment, the material arrangement unit 315 is provided to automatically arrange the disorderly sprayed materials into a linear distribution in an orderly manner, and the linear arrangement is relatively uniform.

[0079] In detail, the material entering the arc-shaped material channel 3151 from the material feed port 3158 will continue to move in a circular motion along the outer circular wall of the arc-shaped material channel 3151 due to the centrifugal effect. The first driving member 3157 drives the L-shaped connecting plate 3155 and the strip plate 3152 to move horizontally back and forth along the outer circular wall of the arc-shaped material channel 3151 through the first eccentric wheel 3156. The rake teeth 3153 near the middle position will push the material entering the arc-shaped material channel 3151 from the material feed port 3158 to both sides. As the length of the rake teeth 3153 on both sides decreases, the material gradually diffuses to both sides and falls into the gap between the two adjacent rake teeth 3153, so that the material is evenly arranged on the same straight line. The linearly arranged material enters the spray channel 317 in sequence, and the airflow entering the spray channel 317 from the air pressure port 3159 sprays the linearly arranged material in the spray channel 317 onto the surface of the embossing roller 100.

[0080] Further, if Figure 4-Figure 6 and Figure 10As shown, the temporary storage unit 316 includes a temporary storage chamber 3161 opened between the lower part of the partition 312 and the outer cylinder 311, a recovery port 3162 opened at one end away from the port of the outer cylinder 311 and located inside the temporary storage chamber 3161, a first rack 3163 slidably and lifted on the inner wall of the temporary storage chamber 3161, a filter plate 3164 provided at the upper end of the first rack 3163 and used to block the recovery port 3162, a hydraulic component 3165 provided at the bottom of the temporary storage chamber 3161, and a hydraulic component 3165 provided at the output end of the hydraulic component 3165 and used to carry the recovery The arc-shaped receiving plate 3166 is used to lift and lower the material, an avoidance gap is opened on the arc-shaped receiving plate 3166 and is used to avoid the filter plate 3164, a first gear 3167 is rotatably set on the inner wall of the temporary storage chamber 3161 and is used to drive the first rack 3163 to lift and lower the filter plate 3164, a second gear 3168 is rotatably set on the inner wall of the temporary storage chamber 3161 and works synchronously with the first gear 3167 through a belt and pulley transmission method, and a second rack 3169 is set at the bottom of the arc-shaped receiving plate 3166 and is used to drive the second gear 3168.

[0081] It should be noted that the recycled material on the arc-shaped receiving plate 3166 will not fall from the avoidance gap. The reason is that the avoidance gap is just compatible with the filter plate 3164 and is of the same thickness as the filter plate 3164. In addition, the filter plate 3164 is longer in the vertical direction. When the filter plate 3164 rises to block the recovery port 3162, the lower end of the filter plate 3164 blocks the avoidance gap. When the filter plate 3164 descends and completely detaches from the recovery port 3162, the upper end of the filter plate 3164 blocks the avoidance gap. That is, the filter plate 3164 always rises and falls within the avoidance gap and will not detach. Therefore, the recycled material on the arc-shaped receiving plate 3166 will not fall from the avoidance gap.

[0082] It is worth mentioning that due to the arc-shaped structural design of the arc-shaped receiving plate 3166, after the arc-shaped receiving plate 3166 rises to the position of the recovery port 3162, the recycled materials scattered on the arc-shaped receiving plate 3166 are gathered toward the lower middle position of the arc-shaped receiving plate 3166 under the action of gravity, and the recovery port 3162 is located exactly in the lower middle position of the arc-shaped receiving plate 3166, which facilitates the recovery port 3162 to absorb the recycled materials on the arc-shaped receiving plate 3166.

[0083] It is also worth mentioning that the purpose of setting up the temporary storage unit 316 is: since the nozzle assembly 31 of the spraying mechanism 3 is continuously spraying, and the weighing unit 511 intermittently detects the amount of recycled material, the recovery channel 353 needs to intermittently stop absorbing recycled material into the mixing bin 51, so that the weighing unit 511 can accurately detect the amount of recycled material, and the replenishing bin 56 can replenish new material into the mixing bin 51, and the weighing unit 511 can transfer the recycled material and new material, leaving sufficient time. During this time period, the temporary storage unit 316 temporarily stores the recycled material to achieve the effect of continuous circulation of spraying and recycled material.

[0084] In this embodiment, by cooperating with the temporary storage unit 316 and the weighing unit 511, on the one hand, the recycled materials in the temporary storage chamber 3161 can be gathered, so that the negative pressure mechanism 4 can absorb the recycled materials on the arc-shaped receiving plate 3166 through the recovery port 3162, thereby reducing the recovery dead angle in the temporary storage chamber 3161 and avoiding the accumulation of recycled materials in the temporary storage chamber 3161; on the other hand, sufficient time can be left for the weighing unit 511 to work, so that the weighing unit 511 can accurately detect the amount of recycled materials and the replenishing bin 56 can accurately replenish materials, thereby achieving the effect of continuous circulation of spraying and recycled materials.

[0085] In detail, when the arc receiving plate 3166 rises to the position of the recycling port 3162, the recycled material in the temporary storage chamber 3161 gathers toward the lower middle position of the arc receiving plate 3166, and the negative pressure mechanism 4 absorbs the recycled material on the arc receiving plate 3166 through the recycling port 3162; when the hydraulic component 3165 drives the arc receiving plate 3166 to descend, the arc receiving plate 3166 drives the second gear 3168 to rotate through the second rack 3169, and the second gear 3168 drives the first gear 3167 to work synchronously through the transmission method of the belt and pulley. The gear 3167 moves up with the filter plate 3164 through the first rack 3163, so that the filter plate 3164 moves up to block the recovery port 3162 without affecting the negative pressure airflow of the negative pressure mechanism 4 through the recovery port 3162. Under the action of the negative pressure airflow, the recycled material will still enter the temporary storage chamber 3161, but will not enter the recovery port 3162. At this time, the recycled material in the temporary storage chamber 3161 is temporarily accumulated on the arc-shaped receiving plate 3166. After the arc-shaped receiving plate 3166 rises to the position of the recovery port 3162, it is absorbed by the reopened recovery port 3162.

[0086] Further, if Figure 1-Figure 4 and Figures 11-16 As shown, the spraying mechanism 3 is slidably arranged on the frame 1 along the length direction of the embossing roller, and further comprises:

[0087] A sliding seat 32 , wherein the sliding seat 32 is matched and slides on the sliding rail 11 of the frame 1 ;

[0088] A positioning portion 33 is rotatably mounted on the sliding seat 32 and has a plurality of waist grooves 331 arranged side by side along the width direction. The nozzle assembly 31 is detachably mounted in the waist grooves 331 .

[0089] a pipe 1 34 , one end of which is connected to the air pressure port 3159 and the other end of which is connected to the air pump unit 36 ​​; and

[0090] Pipe 2 35, one end of which is mounted on an end away from the port of the outer cylinder 311, and a partition plate 351 is provided inside the output port of pipe 2 35;

[0091] The upper portion of the partition plate 351 forms a material delivery channel 352 with the second pipe 35, and the lower portion of the partition plate 351 forms a recovery channel 353 with the second pipe 35. The material delivery channel 352 is connected to the material delivery port 3158, and the recovery channel 353 is connected to the recovery port 3162.

[0092] The negative pressure mechanism 4 includes a pipe three 41 connected to the lower end of the recovery channel 353 , a feed port of the mixing bin 51 is connected to the pipe three 41 , and a discharge port thereof is connected to the pipe two 35 .

[0093] It is worth mentioning that the nozzle assembly 31 can be detachably installed in the waist groove 331, and the position and angle can be adjusted according to the different embossing rollers returned to the factory for repair, so as to adjust the most effective spraying effect and spray recovery effect.

[0094] In this embodiment, the spraying mechanism 3 and the negative pressure mechanism 4 are respectively connected to the spraying channel 317 and the recovery channel 353, so that the sprayed material is output from the top of the partition 312 to the surface of the embossing roller. The mechanical properties of the roller surface can be improved by the spraying treatment, which plays a role in partial stress relief and also improves the fatigue resistance to enhance the quality of the roller; and the excess material falls to the receiving portion 313 under the action of gravity. The receiving portion 313 with a multi-step structure completes the buffering of the falling spray material, so that it falls into the temporary storage chamber 3161 in an orderly manner, avoiding accumulation and blockage at the recovery port.

[0095] Further, if Figure 11 As shown, along the rotation direction opposite to the embossing roller 100 , the nozzle assembly 31 is inclined downward and forms an angle of ∠60° to ∠90° with the tangential direction of the embossing roller 100 .

[0096] That is, the purpose of setting the parameters is to facilitate the full spraying work and to slow down the path of the sprayed material falling to the outside to the greatest extent, so that the negative pressure mechanism 4 can fully absorb the excess sprayed material.

[0097] like Figure 4As shown, the air flow velocity in the pipe 1 34 is v1, and the air flow velocity in the pipe 3 41 is v2, and v2>v1.

[0098] It should be noted that the air pressure in the pipe 34 is at least 6 MPa and at most 10 MPa.

[0099] That is, the purpose of setting the above parameters is to ensure that the recovery speed is greater than the spraying speed. On the one hand, the negative pressure mechanism 4 fully absorbs the excess sprayed material. On the other hand, when a certain amount of recycled material is temporarily stored in the temporary storage unit 316, the pipeline three 41 can simultaneously absorb the recycled material temporarily stored in the temporary storage unit 316 and the material just sprayed, ensuring that the sprayed material can be smoothly recycled.

[0100] Further, if Figures 11-16 As shown, the spray mixing mechanism 5 includes:

[0101] A mixing silo 51 is mounted on a mounting frame 52 , wherein the feed port of the mixing silo 51 is connected to the pipe 3 41 and the discharge port of the mixing silo is connected to the pipe 2 35 ;

[0102] The impurity removal bin 53 is in a negative pressure state and is connected to the upper end of the mixing bin 51 through a first connecting pipe 54. The feed inlet 50 of the impurity removal bin 53 is elastically and sealedly provided with a filter 55; and

[0103] A feeding bin 56 is provided on one side of the mixing bin 51 and stores new material therein. The feeding bin 56 feeds material into the mixing bin 51 through a second connecting pipe 57. The feed end of the second connecting pipe 57 is located below the filter screen 55 and on the same side as the filter screen 55.

[0104] A pressure rod 58 is elastically provided in the impurity removal bin 53 , and the pressure rod 58 penetrates the sealed portion connected to the first connecting pipe 54 . The pressure rod 58 is provided above the filter screen 55 and is in intermittent contact with the filter screen 55 through a linkage assembly.

[0105] The linkage assembly includes a cam 59 rotatably arranged on the first connecting tube 54 and located above the outer end of the pressure rod 58. The sliding seat 32 is driven to move back and forth by a pneumatic member, and the cam 59 and the pneumatic member are synchronously driven by a gear rack transmission.

[0106] As a feasible method, the following can be adopted: the pneumatic part drives the sliding seat 32 to move back and forth in the horizontal direction, and the rack set horizontally and moving synchronously with the pneumatic part is used to drive the gear set to rotate, and the cam 59 is driven synchronously with the gear set through the pulley group. The rotating cam 59 acts intermittently on the pressure rod 58, and the pressure rod 58 is reset under the action of elasticity, and the cycle is repeated. The priority is to save additional power output and reduce production costs. In addition, the previous and subsequent processes are closely connected and easy to control.

[0107] It should be noted that the present application is not limited to the pneumatic parts method using cylinders, and mechanical transmission methods such as screw transmission can also be used.

[0108] Further, if Figure 16-Figure 19 As shown, the mixing bin 51 is provided with a weighing unit 511 for checking the amount of recycled materials and a distribution unit 512 for evenly distributing the recycled materials on the weighing unit 511 from bottom to top.

[0109] The material distribution unit 512 includes a first sieve plate 5121 disposed inside the mixing bin 51, a second sieve plate 5122 slidably disposed on the first sieve plate 5121, two sets of corrugated plates 5123 symmetrically and obliquely disposed between the sides of the second sieve plate 5122 and the inner wall of the mixing bin 51, a second driving chamber 5124 disposed inside the wall of the mixing bin 51, a transmission rod 5125 disposed on a side of the second sieve plate 5122 and having one end extending into the second driving chamber 5124, a second driving member disposed inside the second driving chamber 5124, a second eccentric wheel 5126 disposed at the output end of the second driving member and used to drive the transmission rod 5125 to carry the second sieve plate 5122 for reciprocating horizontal movement on the first sieve plate 5121, a second annular limiting groove disposed on the circumferential side of the second eccentric wheel 5126, and a second limiting block 5127 disposed at one end of the transmission rod 5125 and slidingly engaged with the inner wall of the second annular limiting groove.

[0110] The weighing unit 511 includes a guide plate 5111 rotatably provided by a torsion spring, a sliding chamber 5112 provided on a side surface away from a hinged position of the guide plate 5111, an extension plate 5113 slidably provided in the sliding chamber 5112 and extending to the inner wall of the mixing bin 51, an elastic member 5114 provided between the inner wall of the sliding chamber 5112 and the extension plate 5113, a third driving chamber 5115 provided in the guide plate 5111, a third driving member provided in the third driving chamber 5115, a reel 5116 provided at an output end of the third driving member, and a steel wire 5117 wound around the reel 5116 and having one end extending through the sliding chamber 5112 and connected to the extension plate 5113.

[0111] A detector for detecting the rotation angle of the guide plate 5111 is provided at the hinge position of the guide plate 5111, and the detector controls the amount of output of the feeding bin 56 through the sensor.

[0112] It should be noted that the particles in the recovered materials are inconsistent, so the amount recovered by the mixing bin 51 is different each time, and the nozzle assembly 31 of the spraying mechanism 3 sprays materials continuously, and the material sprayed per unit time is certain, so the new material that needs to be replenished in time is also different. In this application, the guide plate 5111 is elastically installed and rotatably set, and the detector is used to detect the rotation angle of the guide plate 5111. According to the different angles detected each time, the metering valve of the replenishment bin 56 is controlled to discharge the material, and then the amount of material replenished by the replenishment bin 56 to the mixing bin 51 is controlled, thereby ensuring that the amount of material sprayed for the spraying work is sufficient.

[0113] It is worth mentioning that since the nozzle assembly 31 of the spraying mechanism 3 sprays material continuously, and the material sprayed per unit time is certain, the recycled material in the mixing bin 51 cannot come in continuously. The reason is that: only during the time period when the recycled material is suspended from entering the mixing bin 51, the detector can accurately detect the angle of rotation of the guide plate 5111 each time, and the feeding bin 56 can accurately feed the material, and then output the recycled material and new material on the guide plate 5111 downward. During the time period when the recycled material is suspended from entering the mixing bin 51, the temporary storage unit 316 temporarily stores the recycled material, thereby achieving the effect of continuous circulation of the sprayed and recycled materials.

[0114] It is also worth mentioning that during the downward rotation of the guide plate 5111, the extension plate 5113 pops outward under the drive of the elastic member 5114, ensuring that the extension plate 5113 always rests against the inner wall of the mixing bin 51, preventing the recycled material on the guide plate 5111 from rolling down, thereby facilitating accurate measurement of the recycled material each time.

[0115] In addition, the purpose of setting up the feeding unit 512 is that: due to the inconsistency of the particles in the recycled material and the different amounts of recycled material absorbed by the negative pressure mechanism 4 into the mixing bin 51, the positions of the recycled material falling on the guide plate 5111 are different, resulting in uneven recycling of the material on the guide plate 5111, which affects the guide plate 5111 in measuring the amount of recycled material thereon according to the rotation angle; therefore, the feeding unit 512 can oscillate and level the recycled material entering the mixing bin 51, so that the recycled material falls evenly onto the guide plate 5111, which is beneficial to the measurement of the recycled material each time, and in the process of oscillating and leveling the material, the dust in the recycled material is caused to fly, which is beneficial to the impurity removal bin 53 to absorb the dust.

[0116] In this embodiment, by cooperating with the set weighing unit 511 and the distributing unit 512, on the one hand, the amount of recycled material each time can be accurately measured, and the replenishing bin 56 can be replenished accurately, thereby ensuring the dynamic balance between the spraying amount and the recycled material amount, and achieving the effect of continuous circulation of the spraying and recycled materials; on the other hand, the recycled material entering the mixing bin 51 can be oscillated and evenly mixed, so that the recycled material falls evenly onto the guide plate 5111, which is convenient for accurately measuring the recycled material each time.

[0117] In detail, the negative pressure mechanism 4 intermittently absorbs the recycled material into the feeding bin 56, and the second driving member drives the transmission rod 5125 to move the second sieve plate 5122 back and forth horizontally on the first sieve plate 5121 through the second eccentric wheel 5126, so that the second sieve plate 5122 oscillates and mixes the recycled material. When the sieve holes of the second sieve plate 5122 and the first sieve plate 5121 are aligned, the recycled material on the second sieve plate 5122 falls onto the guide plate 5111. As the recycled material on the guide plate 5111 gradually increases, the guide plate 5111 rotates downward, and the extension plate 5113 pops outward under the drive of the elastic member 5114 and always rests on the inner wall of the mixing bin 51. After a specified time, the recycled material stops entering the feeding bin 56. During the feeding stop time period, the detector detects the rotation angle of the guide plate 5111, and controls the metering valve of the feeding bin 56 according to the different angles detected each time, thereby controlling the amount of feeding the feeding bin 56 to the mixing bin 51 each time. Then, the third driving member drives the winding wheel 5116 to wind up the steel wire 5117, so that the steel wire 5117 pulls the extension plate 5113 back into the sliding cavity 5112 of the guide plate 5111. Since the extension plate 5113 is separated from the inner wall of the mixing bin 51, the recycled material and new material on the guide plate 5111 are output downward to the bottom of the mixing bin 51. Then, the guide plate 5111 rotates upward and resets, and the extension plate 5113 slides outward and resets under the drive of the elastic member 5114, ready for the next measurement of recycled material.

[0118] Furthermore, the abrasive materials used in blasting usually include corundum, quartz sand, brown corundum and the like.

[0119] Example 2

[0120] like Figure 20 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0121] Furthermore, the pipe 1 34 , the pipe 2 35 , and the pipe 3 41 are all two-section structures, and the connection 61 thereof is provided with an adjustment portion 6 , the adjustment portion 6 including a bellows structure 62 with a sealing sleeve provided outside the connection 61 and a pipe 63 embedded in the connection 61 and connected to the bellows structure 62 ;

[0122] The inner walls at both ends of the connecting pipe 63 are of an outward-facing eight-shaped structure.

[0123] It should be noted that the nozzle assembly 31 is provided individually. Its purpose is that the specifications of the embossing rollers returned to the factory for repair are inconsistent, and the horizontal movement distance of the single nozzle assembly 31 can be controlled by matching the length of the embossing roller; in addition, there is a spacing between multiple nozzles, and the spraying effect at this spacing is poor; however, when the single nozzle assembly 31 is spraying, in order to ensure that the outer end of the nozzle assembly 31 is at the same distance from the embossing roller, the pipe 1 34, the pipe 2 35 and the pipe 3 41 will be stretched or compressed, thereby reducing the service life of the product.

[0124] In this embodiment, by providing the adjustment portion 6, the spray mechanism 3 is able to move within a limited translation range. When the adjustment portion 6 is stretched or compressed, the bellows structure 62 will not cause deformation of the pipe 1 34, the pipe 2 35 and the pipe 3 41, while ensuring that the distance between the outer end of the nozzle assembly 31 and the embossing roller is consistent, thereby improving the service life of the pipe. Combined with the connection between the connecting pipe 63 and the pipe, it is ensured that during the deformation of the bellows structure 62, the spray material or airflow passing through the connection will not change in cross-sectional area at that location, that is, the cross-sectional area passing through the connection is always consistent, thereby ensuring the smoothness of the flow of the spray material or airflow at that location, and ensuring that the amount of spray material on the roller surface at different horizontal positions is consistent, thereby improving the spraying effect.

[0125] It should be noted that the inner walls of both ends of the connecting pipe 63 are of an outward-facing eight structure and are connected to the bellows structure 62. The stretching or compression of the bellows structure 62 is used to synchronously drive the movement of the connecting pipe 63 in the pipeline. During the movement, the two ends of the connecting pipe 63 synchronously shovel the material on the inner wall of the pipeline connection to avoid the accumulation and adhesion of the sprayed material at the connection, thereby ensuring the smooth movement of the sprayed material.

[0126] Working process:

[0127] Step 1: spraying process. First, the nozzle assembly 31 of the spraying mechanism 3 adjusts the spray material 103 into a linear arrangement, and then sprays the linearly arranged spray material as a whole along a straight path horizontally onto the outer surface of the embossing roller 100, and performs surface treatment on it.

[0128] Step 2, waste material recycling process, synchronous with step 2, when the spraying work is in progress, the negative pressure mechanism 4 connected to the nozzle assembly 31 absorbs the excess material 101 in time;

[0129] Step 3: Dust removal process: the absorbed material is transferred to the spray mixing mechanism 5, and the fine dust and the fine material generated by the destruction pass through the filter 55 and enter the impurity removal bin 53 for collection;

[0130] Step 4, new and old material mixing process, synchronous with step 3, the absorbed material is transferred to the spray mixing mechanism 5 for waste treatment and then mixed with part of the new material 102, and the mixed material 103 is passed into the spray mechanism 3 again for cyclic spraying.
