Description

Technical Field

[0001] The present invention relates to the technical field of embossing roll treatment, and particularly to a sandblasting device for reprocessing an embossing roll. Background Art

[0002] The sandblasting process can efficiently and thoroughly remove rust, impurities, machining residual oil stains, etc. on the surface of a matte roll through a high-speed sand flow. After the embossing roll is used by customers, usually, it will become ineffective in three months or be damaged by foreign objects, and finally be sent back to the factory for repair. The sandblasting of the embossing roll is involved in the repair process. It is a process technology that uses a high-speed sand flow to clean or roughen the surface of the roll. During the use of the sandblasting technology, compressed air is used as the power to form a high-speed jet beam in the sandblasting machine, and the abrasive is sprayed onto the surface of the roll at high speed. After the sandblasting treatment, the appearance and shape of the roll will be changed, and the surface mechanical properties will change to a certain extent.

[0003] Chinese Patent CN210997844U discloses a copper roll automatic grinding and sandblasting device, including a frame, and also including a mounting plate, a moving seat, a grinding mechanism and a sandblasting mechanism. The mounting plate is fixed on the frame, the moving seat is horizontally and movably arranged on the mounting plate through a moving mechanism. 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 moving seat, the first lifting unit is arranged on the first fixed seat and is used to drive the first motor to move linearly up and down, and 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 moving seat and is located on one side of the first fixed seat. The second lifting unit is fixed on the second fixed seat, and the sandblasting head is installed on the support plate and is communicated with an external sandblasting tank.

[0004] However, in the actual use process, the inventor found that during the surface treatment of the embossing roll, the sandblasting device performs sandblasting in a spraying surface. Due to the gravity effect, the distribution of the abrasive within the spraying surface is uneven, resulting in different cleaning strengths of the spraying surface and the problem that the surface of the embossing roll is not smoothly cleaned. Summary of the Invention

By providing a sandblasting device for reprocessing an embossing roll, the abrasive arranged linearly can be sprayed onto the outer surface of the embossing roll as a whole horizontally along a straight path, converting the spraying surface into a spraying ray mode of the abrasive, ensuring uniform distribution of the abrasive, improving the cleaning effect of the surface of the embossing roll, and making the surface of the embossing roll cleaner and smoother.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0040] Embodiment 1 As Figures 1 - 19 shown, a sandblasting device for reprocessing an embossing roller includes a frame 1 and a clamping unit 2 installed 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. It further includes a spraying and mixing mechanism 5 arranged on one side of the embossing roller 100 and a spraying mechanism 3 that is communicated with the spraying and mixing mechanism 5 and is used to spray the spraying material onto the surface of the embossing roller; The nozzle assembly 31 of the spraying mechanism 3 first adjusts the sprayed materials 103 to be linearly arranged, and then sprays the linearly arranged sprayed materials as a whole laterally along a straight path on the outer surface of the embossing roller 100. The redundant materials 101 are timely recovered by the negative pressure mechanism 4 communicated with the nozzle assembly 31. The nozzle assembly 31 intermittently stores the recovered materials, and the recovered materials are transferred to the spraying and mixing mechanism 5 for waste treatment, and a certain amount of new materials are supplemented as needed for mixing. The mixed materials are then fed into the spraying mechanism 3 again for cyclic spraying and conveying work.

[0041] It should be noted that during the maintenance process of the present application, in order to prevent damage to the roller surface, the following limited measures are also taken: 1. The embossing roller does not directly contact the ground, and the embossing rollers to be processed in the lathe and grinder areas are placed on wooden mats. 2. After the grinder processing is completed, it is wrapped with plastic wrap and placed on a sawhorse. 3. After the polishing machine finishes processing, it must be packaged with a softened packaging bag to ensure that it will not be scratched. 4. The same measures are taken for embossing and polishing. 5. After the spraying is completed, it is oiled, packaged with a softened packaging bag, and packaged in a wooden box for transfer to electroplating. 6. After electroplating, the roller surface is hardened, and scratches by ordinary hard objects and the like do not affect the surface quality. So far, no problem of damaging the roller surface has occurred after electroplating.

[0042] During the above process, if a problem of roller surface damage occurs, even a very small defect, it is necessary to return to the lathe and start over.

[0043] Based on the above working conditions, during the spraying treatment of the embossing roller in the present application, it is not convenient to set an outer shell outside the frame 1 to cover the spraying mechanism 3 to avoid unnecessary wear and friction during the disassembly and installation process. The manual handling space margin in the open space is sufficient and it is not easy to be knocked. However, it is precisely because of this that the spraying mechanism 3 will cause the sprayed materials to overflow the workshop during the spraying work. Therefore, it is necessary to recover the sprayed materials.

[0044] It is worth mentioning that by integrally setting the spraying mechanism 3 and the negative pressure mechanism 4 and using a special pipeline structure, the sprayed materials are timely adsorbed and recovered, and then the sprayed materials and the recovered materials form an orderly and stable conveying direction, avoiding the sprayed materials splashing to other positions of the embossing roller 100, causing damage to the embossing roller 100 and further causing environmental pollution in the workshop.

[0045] In this embodiment, by cooperating the spraying mechanism 3 and the clamping unit 2, on the one hand, it is possible to first adjust the sprayed materials to be linearly arranged, and then spray the linearly arranged sprayed materials as a whole laterally along a straight path on the outer surface of the embossing roller. The spraying method that converts from a spraying surface to a spraying ray ensures uniform distribution of the sprayed materials, improves the cleaning effect of the embossing roller surface, and makes the embossing roller surface cleaner and smoother. On the other hand, it can automatically arrange the disordered sprayed materials in an orderly linear distribution. The linear arrangement is relatively uniform, and the sprayed materials distributed along the straight line are not prone to missing positions or broken lines, ensuring uniform distribution of the sprayed materials on the straight line.

[0046] Specifically, first, the nozzle assembly 31 of the spraying mechanism 3 first adjusts the sprayed materials 103 to be linearly arranged, and then sprays the linearly arranged sprayed materials as a whole laterally along a straight path on the outer surface of the embossing roller 100 and performs surface treatment work on it. Then, when the spraying work is in progress, the negative pressure mechanism 4 communicated with the nozzle assembly 31 timely absorbs the excess materials 101. The absorbed materials are transferred to the spraying and mixing mechanism 5. The fine dust and the overly fine materials generated by being damaged pass through the filter screen 55 and enter the impurity removal bin 53 for collection. Then, the absorbed materials are transferred to the spraying and mixing mechanism 5 for waste treatment and then mixed with some new materials 102. The mixed materials 103 are fed into the spraying mechanism 3 again for cyclic spraying work.

[0047] Further, as Figures 3 - 5 shown, the nozzle assembly 31 includes an outer cylinder body 311, a partition portion 312 integrally arranged inside the outer cylinder body 311 and inclined upward near the outer port, several groups of material receiving portions 313 arranged below the partition portion 312 and extending stepwise outward in the vertical direction in sequence, a brush portion 314 arranged on the circumferential direction of the end of the outer cylinder body 311, a material aligning unit 315 arranged inside the partition portion 312 and used to adjust the sprayed materials to be linearly arranged, and a temporary storage unit 316 arranged at the position below the partition portion 312; A spraying channel 317 is formed between the upper part of the partition portion 312 and the outer cylinder body 311.

[0048] It is worth mentioning that in this application, by setting the brush portion 314, when the spraying process is in progress, on the one hand, it limits the spraying materials in a regional manner, so that the excess materials are fully absorbed in a small range. At the same time, the brush portion 314 cleans the surface of the embossing roller during rotation, collects the excess sprayed materials remaining on the roller surface, improves the recovery rate, and also avoids the sprayed materials remaining on the roller surface from affecting the next spraying work.

[0049] In addition, the multi-stage stepped structure of the material receiving portion 313 can buffer the falling sprayed materials so that they orderly fall into the temporary storage cavity 3161.

[0050] Further, as Figures 4 - 9As shown in the figure, the columnar material feeding unit 315 includes an arc-shaped columnar material feeding channel 3151 opened inside the partition portion 312 and having its outlet end communicating with the material spraying channel 317, a strip plate 3152 embedded and slidably disposed at the outlet end of the arc-shaped columnar material feeding channel 3151, several groups of rake teeth 3153 disposed on one side surface of the strip plate 3152 and having their lengths decreasing sequentially from the middle to both sides, a first driving cavity 3154 opened inside the partition portion 312, an L-shaped connecting plate 3155 disposed on the other side surface of the strip plate 3152 and extending into the first driving cavity 3154, a first eccentric wheel 3156 rotatably disposed inside the first driving cavity 3154 through a shaft rod and used for driving the strip plate 3152 to drive the rake teeth 3153 to reciprocate horizontally along the outer circumferential wall of the arc-shaped columnar material feeding channel 3151, a first driving member 3157 disposed inside the first driving cavity 3154 and used for driving the first eccentric wheel 3156, a first annular limiting groove opened on the circumferential side surface of the first eccentric wheel 3156, a first limiting block disposed on the side surface of the L-shaped connecting plate 3155 and slidably engaged with the inner wall of the first annular limiting groove, a material 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 columnar material feeding channel 3151, a pneumatic port 3159 opened at one end away from the port of the outer cylinder 311 and located at the inlet end of the material spraying channel 317, and a diversion and sinking portion 31591 opened at the inlet end of the material spraying channel 317 and used for dispersing the airflow of the pneumatic port 3159.

[0051] It is worth mentioning that the material entering the arc-shaped columnar material feeding channel 3151 from the material feeding port 3158 will continue to move in a circular motion along the outer circumferential wall of the arc-shaped columnar material feeding channel 3151 due to the centrifugal force.

[0052] It is also worth mentioning that for several groups of rake teeth 3153 with their lengths decreasing sequentially from the middle to both sides, the gap between two adjacent rake teeth 3153 just allows one material spraying to pass through. During the simultaneous reciprocating horizontal movement of the rake teeth 3153, the rake teeth 3153 near the middle position will deflect the material entering the arc-shaped columnar material feeding channel 3151 from the material feeding 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 gaps between two adjacent rake teeth 3153 one after another, so that the material is evenly arranged in a straight line.

[0053] It should be noted that the diversion and sinking portion 31591 can disperse the airflow entering the material spraying channel 317 from the pneumatic port 3159, ensure that the air pressure in the material spraying channel 317 is relatively stable, avoid the airflow aggregation from blowing away the materials arranged in a straight line in the material spraying channel 317, and make the materials evenly arranged in a straight line.

[0054] In this embodiment, through the arranged columnar material feeding unit 315, the randomly arranged material sprayings can be automatically arranged in an orderly manner in a linear distribution, and the linear arrangement is relatively uniform.

[0055] Specifically, the material entering the arc-shaped material-listing channel 3151 from the material feeding port 3158 will continue to move along the circumference of the outer wall of the arc-shaped material-listing channel 3151 due to the centrifugal force. The first driving member 3157 drives the L-shaped connecting plate 3155 and the strip plate 3152 through the first eccentric wheel 3156 to drive the rake teeth 3153 to reciprocate horizontally along the outer wall of the arc-shaped material-listing channel 3151. The rake teeth 3153 near the middle position will deflect the material entering the arc-shaped material-listing channel 3151 from the material feeding 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 gaps between two adjacent rake teeth 3153 one after another, so that the material is evenly arranged in a straight line. The linearly arranged material sequentially enters the material spraying channel 317, and the air flow entering the material spraying channel 317 from the air pressure port 3159 sprays the linearly arranged material in the material spraying channel 317 onto the surface of the embossing roller 100.

[0056] Further, as Figures 4 - 6 and Figure 10 shown, the temporary storage unit 316 includes a temporary storage cavity 3161 opened between the lower part of the partition part 312 and the outer cylinder 311, a recovery port 3162 opened at one end far from the port of the outer cylinder 311 and located inside the temporary storage cavity 3161, a first rack 3163 slidably and vertically arranged on the inner wall of the temporary storage cavity 3161, a filter material plate 3164 arranged at the upper end of the first rack 3163 and used to block the recovery port 3162, a hydraulic component 3165 arranged at the bottom of the temporary storage cavity 3161, an arc-shaped receiving plate 3166 arranged at the output end of the hydraulic component 3165 and used to carry the recovered material for lifting, an avoidance notch opened on the arc-shaped receiving plate 3166 and used to avoid the filter material plate 3164, a first gear 3167 rotatably arranged on the inner wall of the temporary storage cavity 3161 and used to drive the first rack 3163 to drive the filter material plate 3164 to lift, a second gear 3168 rotatably arranged on the inner wall of the temporary storage cavity 3161 and synchronously working with the first gear 3167 through the transmission mode of a belt and a belt pulley, and a second rack 3169 arranged at the bottom of the arc-shaped receiving plate 3166 and used to drive the second gear 3168.

[0057] It should be noted that the recycled materials on the arc-shaped receiving plate 3166 will not fall from the avoidance notch. The reason is that the avoidance notch is just adapted to the filter material plate 3164 and has the same thickness as the filter material plate 3164. Moreover, the filter material plate 3164 has a relatively long length in the vertical direction. When the filter material plate 3164 rises to block the recycling port 3162, the lower end of the filter material plate 3164 blocks the avoidance notch. When the filter material plate 3164 descends and completely disengages from the recycling port 3162, the upper end of the filter material plate 3164 blocks the avoidance notch. That is, the filter material plate 3164 always rises and falls within the avoidance notch and will not disengage. Therefore, the recycled materials on the arc-shaped receiving plate 3166 will not fall from the avoidance notch.

[0058] It is worth mentioning that due to the arc-shaped structure design of the arc-shaped receiving plate 3166, after the arc-shaped receiving plate 3166 rises to the position of the recycling port 3162, the recycled materials scattered on the arc-shaped receiving plate 3166 gather towards the lower-middle position of the arc-shaped receiving plate 3166 under the action of gravity, and the recycling port 3162 is exactly located at the lower-middle position of the arc-shaped receiving plate 3166, which is convenient for the recycling port 3162 to absorb the recycled materials on the arc-shaped receiving plate 3166.

[0059] It is also worth mentioning that the purpose of setting the temporary storage unit 316 is as follows: Since the nozzle assembly 31 of the spraying mechanism 3 continuously sprays materials, when the weighing unit 511 intermittently detects the amount of recycled materials, the recycling channel 353 needs to intermittently pause absorbing the recycled materials into the mixing bin 51 to give the weighing unit 511 sufficient time to accurately detect the amount of recycled materials, and for the feeding bin 56 to supplement new materials into the mixing bin 51, and for the weighing unit 511 to transfer the recycled materials and new materials. During this period, the temporary storage unit 316 temporarily stores the recycled materials to achieve the effect of continuous cyclic flow of spraying and recycled materials.

[0060] In this embodiment, through the cooperation of the set temporary storage unit 316 and the weighing unit 511, on the one hand, it can gather the recycled materials in the temporary storage cavity 3161, which is convenient for the negative pressure mechanism 4 to absorb the recycled materials on the arc-shaped receiving plate 3166 through the recycling port 3162, reduce the recycling dead angle in the temporary storage cavity 3161, and avoid the accumulation of recycled materials in the temporary storage cavity 3161. On the other hand, it can leave sufficient time for the weighing unit 511 to work, which is convenient for the weighing unit 511 to accurately detect the amount of recycled materials and for the feeding bin 56 to accurately supply materials, achieving the effect of continuous cyclic flow of spraying and recycled materials.

[0061] Specifically, when the arc-shaped receiving plate 3166 rises to the position of the recovery port 3162, the recovered material entering the temporary storage chamber 3161 gathers towards the relatively low middle position of the arc-shaped receiving plate 3166, and the negative pressure mechanism 4 absorbs the recovered material on the arc-shaped receiving plate 3166 through the recovery port 3162; when the hydraulic component 3165 drives the arc-shaped receiving plate 3166 to descend, the arc-shaped receiving plate 3166 drives the second gear 3168 to rotate through the second rack 3169, the second gear 3168 drives the first gear 3167 to work synchronously through the transmission mode of the belt and pulley, and the first gear 3167 drives the filter plate 3164 to rise through the first rack 3163, so that the filter plate 3164 rises to block the recovery port 3162 without affecting the negative pressure air flow of the negative pressure mechanism 4 through the recovery port 3162. Under the action of the negative pressure air flow, the recovered material will still enter the temporary storage chamber 3161, and the recovered material will not enter the recovery port 3162. At this time, the recovered material in the temporary storage chamber 3161 accumulates and is temporarily stored on the arc-shaped receiving plate 3166. After the arc-shaped receiving plate 3166 rises to the position of the recovery port 3162, it will be absorbed away by the reopened recovery port 3162.

[0062] Further, as Figures 1 - 4 and Figures 11 - 16 shown, the spraying mechanism 3 is slidably arranged on the frame 1 along the length direction of the embossing roller, and it further includes: A sliding seat 32, which is slidably matched on the sliding track 11 of the frame 1; A positioning part 33, which is rotatably arranged on the sliding seat 32 and is provided with a plurality of groups of waist-shaped grooves 331 arranged side by side along the width direction, and the nozzle assembly 31 is detachably installed in the waist-shaped grooves 331; A first pipeline 34, one end of which is communicated with the air pressure port 3159 and the other end is communicated with the air pump unit 36; and A second pipeline 35, one end of which is installed at one end far from the port of the outer cylinder 311, and a partition plate 351 is arranged inside the output port of the second pipeline 35; Above the partition plate 351 forms a material conveying channel 352 with the second pipeline 35, and below the partition plate 351 forms a recovery channel 353 with the second pipeline 35. The material conveying channel 352 is butt-connected and communicated with the material conveying port 3158, and the recovery channel 353 is butt-connected and communicated with the recovery port 3162; The negative pressure mechanism 4 includes a third pipeline 41 communicated with the lower end of the recovery channel 353. The feed inlet of the mixing bin 51 is communicated with the third pipeline 41, and its discharge outlet is communicated with the second pipeline 35.

[0063] It is worth mentioning that by detachably installing the nozzle assembly 31 in the waist groove 331, the position and angle can be adjusted according to different embossing rollers for return repair, so as to debug to the most effective spraying effect and spraying recovery effect.

[0064] In this embodiment, the spraying mechanism 3 and the negative pressure mechanism 4 are respectively connected in the spraying channel 317 and the recovery channel 353, so that the sprayed material is output from above the partition part 312 to the surface of the embossing roller. The mechanical properties of the roller surface can be improved through 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 material receiving part 313 under the action of gravity. The material receiving part 313 with a multi-stage stepped structure completes the buffering of the falling of the sprayed material, so that it orderly falls into the temporary storage cavity 3161, avoiding the phenomenon of accumulation and blockage at the recovery port.

[0065] Furthermore, as Figure 11 shown, along the rotation direction opposite to that of the embossing roller 100, the nozzle assembly 31 is inclined downward and forms an angle of ∠60° - ∠90° with the tangent direction of the embossing roller 100.

[0066] That is, the purpose of the above set parameters is to facilitate the full spraying work and maximize the reduction of the path for the sprayed material to fall outside, so that the negative pressure mechanism 4 can fully absorb the excess sprayed material.

[0067] As Figure 4 shown, the air flow velocity in the first pipeline 34 is v1, and the air flow velocity in the third pipeline 41 is v2, and v2 > v1.

[0068] It should be noted that the air pressure in the first pipeline 34 is at least 6 Mpa and at most 10 Mpa.

[0069] That is, the purpose of the above set parameters is to ensure that the recovery speed is greater than the spraying speed. On the one hand, the negative pressure mechanism 4 can fully absorb the excess sprayed material. On the other hand, when a certain amount of recovered material is temporarily stored inside the temporary storage unit 316, the third pipeline 41 can absorb the recovered material temporarily stored in the temporary storage unit 316 and the just-sprayed material at the same time, ensuring the smooth recycling of the sprayed material.

[0070] Furthermore, as Figures 11 - 16 shown, the spraying mixing mechanism 5 includes: A mixing bin 51, which is installed on the mounting frame 52. The feed inlet of the mixing bin 51 is connected to the third pipeline 41, and its discharge outlet is connected to the second pipeline 35; An impurity removal bin 53, which is in a negative pressure state inside, and is connected to the upper end of the mixing bin 51 through a first connecting pipe 54. A filter screen 55 is elastically and sealingly arranged at the feed inlet 50 of the impurity removal bin 53; and The replenishment bin 56 is arranged on one side of the mixing bin 51 and stores new materials therein. The replenishment bin 56 replenishes materials into the mixing bin 51 through the second connecting pipe 57. The feeding end of the second connecting pipe 57 is located below the filter screen 55 and is arranged on the same side. A pressure rod 58 is elastically arranged in the impurity removal bin 53. The part of the pressure rod 58 penetrating and connecting the first connecting pipe 54 is hermetically arranged. The pressure rod 58 is arranged above the filter screen 55 and is intermittently in contact with the filter screen 55 through a linkage assembly.

[0071] The linkage assembly includes a cam 59 rotatably arranged on the first connecting pipe 54 and above the outer end of the pressure rod 58. The sliding seat 32 is driven to reciprocate by a pneumatic component. Synchronous transmission is carried out between the cam 59 and the pneumatic component through a gear-rack transmission method.

[0072] As an implementable method, the pneumatic component drives the sliding seat 32 to reciprocate horizontally. The rack that moves synchronously with the pneumatic component and is horizontally arranged drives the gear set to rotate. The cam 59 is synchronously driven to rotate through a pulley set with the gear set. The rotating cam 59 acts on the upper part of the pressure rod 58 intermittently. The pressure rod 58 resets under the elastic action, and so on in a cycle. Its priority lies in saving additional power output and reducing production costs. In addition, the front and back processes are closely linked and easy to control.

[0073] It should be noted that this application is not limited to the pneumatic component method using a cylinder, and mechanical transmission methods such as screw drive can also be used.

[0074] Furthermore, as Figures 16 - 19 shown, a weighing unit 511 for checking the amount of recycled materials and a cloth distributing unit 512 for evenly distributing the recycled materials on the weighing unit 511 are respectively arranged in the mixing bin 51 from bottom to top. The cloth distributing unit 512 includes a first sieve plate 5121 arranged inside the mixing bin 51, a second sieve plate 5122 slidably arranged on the first sieve plate 5121, two groups of corrugated plates 5123 symmetrically and obliquely arranged between the side of the second sieve plate 5122 and the inner wall of the mixing bin 51, a second driving cavity 5124 opened inside the bin wall of the mixing bin 51, a transmission rod 5125 arranged on one side of the second sieve plate 5122 and with one end extending into the second driving cavity 5124, a second driving component arranged inside the second driving cavity 5124, a second eccentric wheel 5126 arranged at the output end of the second driving component and used to drive the transmission rod 5125 to drive the second sieve plate 5122 to reciprocate horizontally on the first sieve plate 5121, a second annular limiting groove opened on the circumferential side of the second eccentric wheel 5126, and a second limiting block 5127 arranged at one end of the transmission rod 5125 and slidably matched with the inner wall of the second annular limiting groove. The weighing unit 511 includes a guide plate 5111 elastically and rotatably arranged through a torsion spring, a sliding cavity 5112 opened on one side surface far from the hinged position of the guide plate 5111, an extension plate 5113 slidably arranged inside the sliding cavity 5112 and extending to the inner wall of the mixing bin 51, an elastic member 5114 arranged between the inner wall of the sliding cavity 5112 and the extension plate 5113, a third driving cavity 5115 opened inside the guide plate 5111, a third driving member arranged inside the third driving cavity 5115, a winding wheel 5116 arranged at the output end of the third driving member, and a steel wire 5117 wound around the winding wheel 5116 and having one end thereof penetrating into the sliding cavity 5112 and connected to the extension plate 5113; A detector for detecting the rotation angle of the guide plate 5111 is arranged at the hinged position of the guide plate 5111, and the detector controls the output amount of the replenishing bin 56 through a sensor.

[0075] It should be noted that the particles in the recycled material are inconsistent, so the amount of recycled material received by the mixing bin 51 each time is different. The nozzle assembly 31 of the spraying mechanism 3 sprays material continuously, and the amount of material sprayed per unit time is constant. Therefore, the amount of new material that needs to be replenished in a timely manner is also different. In this application, through the elastically mounted and rotatably arranged guide plate 5111, the detector detects the rotation angle of the guide plate 5111. According to the different angles detected each time, the metering valve for the discharge of the replenishing bin 56 is controlled, and then the replenishing amount of the replenishing bin 56 to the mixing bin 51 each time is controlled, thereby ensuring that the spraying amount of the spraying work is sufficient.

[0076] It is worth mentioning that since the nozzle assembly 31 of the spraying mechanism 3 sprays material continuously and the amount of material sprayed per unit time is constant, while the recycled material in the mixing bin 51 cannot enter continuously. The reason is that only during the period when the recycled material stops entering the mixing bin 51, the detector can accurately detect the rotation angle of the guide plate 5111 each time, the replenishing bin 56 can replenish material accurately, and then the recycled material and new material on the guide plate 5111 are output downward. During the period when the recycled material stops entering the mixing bin 51, the temporary storage unit 316 temporarily stores the recycled material, achieving the effect of continuous cyclic flow of spraying and recycled material.

[0077] It is also worth mentioning that during the downward rotation of the guide plate 5111, the extension plate 5113 pops out outward under the drive of the elastic member 5114, ensuring that the extension plate 5113 always abuts against the inner wall of the mixing bin 51, preventing the recycled material on the guide plate 5111 from rolling downward, and facilitating accurate measurement of the recycled material each time.

[0078] In addition, the purpose of setting the cloth-feeding unit 512 is as follows: due to the inconsistent 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 distribution of the recycled material on the guide plate 5111, which affects the measurement of the amount of recycled material on the guide plate 5111 according to the rotation angle. Therefore, the cloth-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 during the process of oscillating and leveling the material, the dust in the recycled material will fly, which is beneficial to the dust removal bin 53 to absorb the dust.

[0079] In this embodiment, through the cooperation of the weighing unit 511 and the cloth-feeding unit 512 set, on the one hand, it can accurately measure the amount of recycled material each time, and the feeding bin 56 can accurately feed materials, ensuring the dynamic balance between the spraying amount and the recycled material amount, and achieving the effect of continuous cyclic flow of the spraying material and the recycled material; on the other hand, it can oscillate and level the recycled material entering the mixing bin 51, so that the recycled material falls evenly onto the guide plate 5111, facilitating the accurate measurement of the recycled material each time.

[0080] Specifically, the negative-pressure mechanism 4 intermittently absorbs the recycled material into the feeding bin 56. The second driving member drives the transmission rod 5125 through the second eccentric wheel 5126 to drive the second sieve plate 5122 to reciprocate horizontally on the first sieve plate 5121, so that the second sieve plate 5122 oscillates and levels 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 out outward under the drive of the elastic member 5114 and always abuts against the inner wall of the mixing bin 51. After a specified time, the recycled material stops entering the feeding bin 56. During the period of stopping feeding, the detector detects the rotation angle of the guide plate 5111. According to the different angles detected each time, the metering valve for discharging materials from the feeding bin 56 is controlled, and then the feeding amount of the feeding bin 56 into the mixing bin 51 each time is controlled. Then, the third driving member drives the winding wheel 5116 to wind 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 the 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 to reset, and the extension plate 5113 slides out and resets outward under the drive of the elastic member 5114, waiting to measure the recycled material next time.

[0081] Furthermore, the abrasive materials for spraying usually include components such as emery, quartz sand, and brown fused alumina.

[0082] Embodiment 2 As Figure 20 shown, where the same or corresponding components as those in the first embodiment are denoted by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the second embodiment and the first embodiment are as follows: Further, the first pipeline 34, the second pipeline 35, and the third pipeline 41 are all of two-section structures, and adjusting portions 6 are provided at their connection portions 61. The adjusting portion 6 includes a corrugated pipe structure 62 hermetically sleeved outside the connection portion 61 and a connecting pipe 63 embedded inside the connection portion 61 and connected to the corrugated pipe structure 62; The inner walls at both ends of the connecting pipe 63 are of an outwardly flared structure.

[0083] It should be noted that a single nozzle assembly 31 is provided. The purpose is that the specifications of the embossing rollers returned to the factory for repair are inconsistent, and the distance of the horizontal movement of the single nozzle assembly 31 can be controlled by matching the length of the embossing roller. In addition, there are intervals between multiple nozzles, and the spraying effect at these intervals is poor. However, during the spraying operation of the single nozzle assembly 31, in order to ensure that the distance between the outer end of the nozzle assembly 31 and the embossing roller is consistent, the first pipeline 34, the second pipeline 35, and the third pipeline 41 will be stretched or pressed, reducing the service life of the product.

[0084] In this embodiment, by providing the adjusting portion 6, when the spraying mechanism 3 is within a limited translation range and the corrugated pipe structure 62 is stretched or compressed, on the premise of ensuring that the distance between the outer end of the nozzle assembly 31 and the embossing roller is consistent, the first pipeline 34, the second pipeline 35, and the third pipeline 41 will not be deformed, improving the service life of the pipeline. Then, combined with the embedding of the connecting pipe 63 at the connection of the pipeline, it is further ensured that during the deformation process of the corrugated pipe structure 62, the spraying material or air flow passing through the connection will not change the cross-sectional area at this place, that is, the cross-sectional area passing through the connection is always the same, thereby ensuring the smoothness of the spraying material or air flow passing through this place, and achieving the same spraying amount of the spraying material on the roller surface at different horizontal positions, improving the spraying effect.

[0085] It should be noted that the inner walls at both ends of the connecting pipe 63 are of an outwardly flared structure and are connected to the corrugated pipe structure 62. The stretching or compression of the corrugated pipe structure 62 is used to synchronously drive the movement of the connecting pipe 63 inside the pipeline. During the movement, both ends of the connecting pipe 63 simultaneously perform the work of shoveling the inner wall of the pipeline connection, avoiding the accumulation and adhesion of the spraying material at the connection, and ensuring the smoothness of the spraying material movement.

[0086] Working process: Step 1, spraying process. First, the nozzle assembly 31 of the spraying mechanism 3 adjusts the spraying materials 103 to be linearly arranged, and then the linearly arranged spraying materials are sprayed transversely along a straight path on the outer surface of the embossing roller 100 as a whole, and surface treatment work is carried out on it; Step 2: Scrap recycling process. Synchronously with Step 2, when the spraying operation is in progress, the negative pressure mechanism 4 connected to the spraying port assembly 31 timely absorbs the excess material 101. Step 3: Dust removal process. The absorbed material is transferred into the spraying and mixing mechanism 5. Fine dust and over-fine material generated by being damaged pass through the filter screen 55 and enter the impurity removal bin 53 for collection. Step 4: New and old material mixing process. Synchronously with Step 3, the absorbed material is transferred into the spraying and mixing mechanism 5 for waste treatment and then mixed with part of the new material 102. The mixed material 103 is fed into the spraying mechanism 3 again for cyclic spraying operation.
