[0035] like Figures 1 to 8 As shown, the present invention provides a technical solution, a tank body wall polishing device for processing pectin storage tanks, comprising a base 1, a support frame 4 is fixedly connected to the top of the base 1, a first motor 5 is fixedly connected to the top of the support frame 4, an output end of the first motor 5 extends to the inside of the support frame 4 and is fixedly connected to a screw rod 6, the screw rod 6 is rotatably connected to the support frame 4, an outer wall of the screw rod 6 is connected to a slider 7 through a screw nut pair, the slider 7 is slidably connected to the support frame 4, one end of the slider 7 is fixedly connected to a slide plate 8, one side of the slide plate 8 is fixedly connected to a mounting plate 9, an electric telescopic rod 10 is fixedly connected to the inside of the mounting plate 9, the output end of the electric telescopic rod 10 is fixedly connected to a connecting rod 11, the bottom of the connecting rod 11 is fixedly connected to a third motor 23, and the output end of the third motor 23 is fixedly connected to a grinding disc 24.

[0036] Through the above technical solution, the first motor 5 is started to drive the screw 6 to rotate, so that the slider 7 moves upward, and then the slide plate 8, the electric telescopic rod 10 and the connecting rod 11 are driven to move upward, and then the grinding disc 24 moves upward, and the storage tank is placed on the base 1, and then the grinding disc 24 is controlled to move downward, so that the grinding disc 24 enters the storage tank, and the grinding disc 24 is controlled to move horizontally through the electric telescopic rod 10 so that the grinding disc 24 is close to the inner wall of the storage tank, and the third motor 23 is started to drive the grinding disc 24 to rotate to polish the inner wall of the storage tank, and the position of the storage tank is rotated to adjust the position so that the grinding disc 24 can polish a circle of the inner wall of the storage tank, and by controlling the slider 7 to move up and down, the inner wall of the storage tank can be polished at different depths.

[0037] Specifically, a support ring 12 is fixedly connected to the top of the base 1, a fixed ring 13 is fixedly connected to the top of the support ring 12, a swivel 14 is rotatably connected to the inner wall of the fixed ring 13, six clamping blocks 15 are equidistantly slidably connected to the inner wall of the swivel 14, six first springs 16 are equidistantly arranged inside the swivel 14, one end of the first spring 16 is fixedly connected to the swivel 14, the other end of the first spring 16 is fixedly connected to the clamping block 15, the top of the clamping block 15 is arranged as an inclined surface, a plurality of first rotating shafts 17 are equidistantly fixedly connected to the inner wall of the clamping block 15, a first guide wheel 18 is rotatably connected to the outer wall of the first guide wheel 18, and a plurality of rubber rings 19 are equidistantly fixedly connected to the outer wall of the first guide wheel 18.

[0038] Through the above technical solution, the storage tank is inserted into the rotating ring 14, and the bottom of the storage tank is pressed against the inclined surfaces of the six clamping blocks 15, thereby pushing the six clamping blocks 15 to move toward the inside of the rotating ring 14 at the same time, pressing the six first springs 16, and the first guide wheel 18 is provided to reduce the friction between the clamping blocks 15 and the storage tank, so as to facilitate the downward movement of the storage tank. After the storage tank passes through the six clamping blocks 15, under the action of the six first springs 16, the six clamping blocks 15 clamp and fix the storage tank on all sides to prevent the storage tank from shaking during polishing, and with the cooperation of the six clamping blocks 15, storage tanks of different calibers can be clamped.

[0039] Specifically, the top of the base 1 is rotatably connected to the turntable 2, the top of the turntable 2 is provided with a rubber pad 3, the outer wall of the support ring 12 is fixedly connected to the second motor 21, the output end of the second motor 21 extends to the inside of the support ring 12 and is fixedly connected to the bevel gear 22, and the bottom of the rotating ring 14 is fixedly connected to the gear ring 20, which is meshingly connected to the bevel gear 22.

[0040] Through the above technical solution, the storage tank is placed on the turntable 2, and the friction between the storage tank and the turntable 2 is increased by the rubber pad 3. When the grinding disc 24 polishes the inner wall of the storage tank, the second motor 21 is started to drive the bevel gear 22 to rotate, so that the gear ring 20 rotates, and the rotating ring 14 rotates. The friction between the first guide wheel 18 and the storage tank is increased by the rubber ring 19, so that the rotating ring 14 rotates while driving the storage tank to rotate, and at the same time drives the turntable 2 to rotate, thereby avoiding wear on the bottom of the storage tank.

[0041] Specifically, the outer wall of the third motor 23 is fixedly connected to a connecting plate 25, the inner wall of the connecting plate 25 is slidably connected to a sliding shaft 26, the top of the sliding shaft 26 is fixedly connected to a limiting block 27, the bottom of the sliding shaft 26 is fixedly connected to a fixing frame 29, the bottom of the fixing frame 29 is provided with a through groove 43 used in conjunction with the grinding disc 24, the outer wall of the sliding shaft 26 is sleeved with a second spring 28, the bottom of the second spring 28 is fixedly connected to the fixing frame 29, and the top of the second spring 28 is fixedly connected to the connecting plate 25.

[0042] Through the above technical solution, the side surface of the grinding disc 24 is covered by the set fixing frame 29 to prevent the polishing paste from splashing around as the grinding disc 24 rotates after the polishing paste is applied. When grinding the bottom of the inner wall of the storage tank, the fixing frame 29 contacts the bottom of the storage tank and stops moving, and drives the sliding shaft 26 to slide in the connecting plate 25, compressing the second spring 28. At this time, as the slider 7 moves downward, the grinding disc 24 contacts the bottom of the storage tank, thereby polishing the bottom of the inner wall of the storage tank.

[0043] Specifically, a cavity 35 is opened inside the fixing frame 29, and a pipe 37 is fixedly connected inside the fixing frame 29. One end of the pipe 37 extends into the cavity 35. A sleeve 39 is fixedly connected inside the fixing frame 29 and at the top of the pipe 37. A linkage unit is provided between the sleeve 39 and the connecting plate 25.

[0044] Through the above technical solution, polishing paste is loaded into the cavity 35. When the sliding shaft 26 slides in the connecting plate 25, the polishing paste is squeezed along the pipe 37 to the grinding disc 24 through the provided linkage unit, and the polishing paste is applied to the contact position between the grinding disc 24 and the storage tank, thereby eliminating the numerous steps of manually adding polishing paste again and again.

[0045] Specifically, the linkage unit includes a piston plate 40, which is arranged inside the sleeve 39 and is slidably connected to the sleeve 39. A pull rod 41 is fixedly connected to the top of the piston plate 40. The top of the pull rod 41 passes through the sleeve 39 and is fixedly connected to the connecting plate 25. Two one-way valves 38 are symmetrically arranged inside the pipeline 37 with the sleeve 39 as the center, and the two one-way valves 38 are opened from right to left.

[0046] Through the above technical solution, before polishing the storage tank, the first motor 5 controls the grinding disc 24 to move toward the bottom of the inner wall of the storage tank. After the fixing frame 29 contacts the bottom of the storage tank, the grinding disc 24 is continued to be controlled to move downward. The pull rod 41 is moved downward by squeezing, driving the piston plate 40 to move downward. With the cooperation of the two one-way valves 38, the gas in the sleeve 39 is discharged, and then the grinding disc 24 is controlled to move upward. Under the action of the second spring 28, the fixing frame 29 is moved upward and reset. Under the pulling of the fixing frame 29, The pull rod 41 is driven to move upward, so that the piston plate 40 moves upward. With the cooperation of the two one-way valves 38, the polishing paste in the cavity 35 can be pumped into the sleeve 39 along the pipe 37, and then the grinding disc 24 is controlled to move downward again. Similarly, the piston plate 40 is driven to move downward. With the cooperation of the two one-way valves 38, the polishing paste in the sleeve 39 can be squeezed out along the pipe 37 and smeared on the grinding disc 24. This reciprocating process is repeated, and polishing paste can be added to the grinding disc 24 every time the grinding disc 24 is controlled to grind the bottom of the inner wall of the storage tank.

[0047] Specifically, an extrusion chamber 36 is opened inside the fixed frame 29, and the extrusion chamber 36 is configured to be an arc shape for use with the grinding disc 24. A plurality of discharge ports 42 are opened at equal intervals on one side of the extrusion chamber 36. The discharge ports 42 are communicated with the through groove 43, and the other end of the pipe 37 extends to the interior of the extrusion chamber 36.

[0048] Through the above technical solution, the polishing paste squeezed out from the pipe 37 enters the extrusion chamber 36 and flows along the inner wall of the extrusion chamber 36, thereby increasing the coverage area of ​​the polishing paste. The polishing paste is then squeezed out from a plurality of discharge ports 42, thereby evenly applying a layer of polishing paste to the grinding disc 24, thereby preventing the polishing paste from accumulating and being easily thrown off by the grinding disc 24.

[0049] Specifically, the outer wall of the fixing frame 29 is symmetrically fixedly connected to two first side plates 30, the inner walls of the two first side plates 30 are slidably connected to the second side plates 32, the inner walls of the two second side plates 32 are fixedly connected to the second rotating shaft 33, the outer walls of the two second rotating shafts 33 are rotatably connected to the second guide wheels 34, and the interior of the two first side plates 30 is provided with a third spring 31, one end of the third spring 31 is fixedly connected to the fixing frame 29, and the other end of the third spring 31 is fixedly connected to the second side plate 32.

[0050] Through the above technical solution, when the grinding disc 24 is controlled to be close to the inner wall of the storage tank, the two second side plates 32 first contact the inner wall of the storage tank, and under the squeezing of the storage tank, the two second side plates 32 slide in the two first side plates 30 at the same time, pressing the two third springs 31. Therefore, after the grinding disc 24 is close to the inner wall of the storage tank, the two second side plates 32 are close to the inner wall of the storage tank, and the two first side plates 30 cooperate with the two second side plates 32 to block the two sides of the grinding disc 24, prevent the polishing paste from being thrown out to the side, and concentrate the polishing paste on the grinding disc 24, thereby improving the polishing effect of the grinding disc 24.

[0051] Specifically, the inner wall of the grinding disc 24 is equidistantly slidably connected with a plurality of slide rods 44, the slide rods 44 are obliquely installed, one end of the slide rod 44 is fixedly connected with a grinding block 46, the top of the grinding block 46 is set as an inclined surface, and a plurality of discharge grooves 47 are equidistantly opened on the inclined surface of the top of the grinding block 46, and a plurality of fourth springs 45 are equidistantly arranged inside the grinding disc 24, one end of the fourth spring 45 is fixedly connected to the grinding disc 24, and the other end of the fourth spring 45 is fixedly connected to the slide rod 44.

[0052] Through the above technical scheme, when grinding the angle at the bottom of the inner wall of the storage tank, the grinding disc 24 is controlled to move toward the angle at the bottom of the inner wall of the storage tank, and under the action of the fourth spring 45, the grinding block 46 first contacts the angle at the bottom of the inner wall of the storage tank, and then the grinding disc 24 is controlled to move. Under the squeezing of the storage tank, the slide bar 44 slides in the grinding disc 24, pressing the fourth spring 45, so that when the grinding disc 24 rotates, under the reaction force of the fourth spring 45, the grinding block 46 is always close to the angle at the bottom of the inner wall of the storage tank, and part of the polishing paste falling from the discharge port 42 falls on the grinding block 46, slides down along the inclined surface of the top of the grinding block 46, and flows downward through the discharge trough 47, adding polishing paste to the joint between the grinding block 46 and the angle of the storage tank, thereby improving the polishing effect of the angle of the storage tank.

[0053] An operating method of a tank inner wall polishing device for processing a pectin storage tank, the operating method is applicable to the above-mentioned tank inner wall polishing device for processing a pectin storage tank, and the steps of the method are as follows:

[0054] S1: Start the first motor 5 to control the slider 7 to move upward to the highest position, insert the storage tank into the rotating ring 14, and place it on the turntable 2, start the second motor 21, control the rotating ring 14 to rotate, and drive the storage tank to rotate;

[0055] S2: Start the first motor 5 to control the slider 7 to move downward, so that the grinding disc 24 enters the storage tank, and control the grinding disc 24 to move horizontally through the electric telescopic rod 10, so that the grinding disc 24 is close to the inner wall of the storage tank, and start the third motor 23 to drive the grinding disc 24 to rotate, so as to polish the inner wall of the storage tank;

[0056] S3: Polishing paste is loaded into the cavity 35 . When polishing the storage tank, the first motor 5 is used to control the grinding disc 24 to move downward, and the fixing frame 29 is pressed to squeeze the polishing paste in the cavity 35 onto the grinding disc 24 .

[0057] When in use, the polishing paste is loaded into the cavity 35, and the first motor 5 is started to drive the screw rod 6 to rotate, so that the slider 7 moves upward, the slide plate 8 moves upward, the electric telescopic rod 10 moves upward, the connecting rod 11 moves upward, and the grinding disc 24 moves upward. The storage tank is inserted into the rotating ring 14, and the bottom of the storage tank is pressed against the inclined surfaces of the six clamping blocks 15, thereby pushing the six clamping blocks 15 to move into the inside of the rotating ring 14 at the same time, and the six first springs 16 are pressed. The friction between the clamping blocks 15 and the storage tank can be reduced by the first guide wheel 18, so that the storage tank can be easily moved downward. After passing through the six clamping blocks 15, the storage tank is placed on the turntable 2. Under the action of the six first springs 16, the six clamping blocks 15 clamp and fix the four sides of the storage tank to prevent the storage tank from being moved. It shakes during polishing, and with the cooperation of the six clamping blocks 15, it can clamp storage tanks of different calibers, and then control the grinding disc 24 to move downward so that the grinding disc 24 enters the storage tank. The electric telescopic rod 10 controls the grinding disc 24 to move horizontally so that the grinding disc 24 is close to the inner wall of the storage tank. The third motor 23 is started to drive the grinding disc 24 to rotate and polish the inner wall of the storage tank. By controlling the slider 7 to move up and down, different depths of the inner wall of the storage tank can be polished. The friction between the storage tank and the turntable 2 is increased by the rubber pad 3. When the grinding disc 24 polishes the inner wall of the storage tank, the second motor 21 is started to drive the bevel gear 22 to rotate, so that the gear ring 20 rotates, and the rotating ring 14 rotates. The friction between the first guide wheel 18 and the storage tank is increased by the rubber ring 19. The rotating ring 14 is rotated to drive the storage tank to rotate, and the rotating disk 2 is also driven to rotate to avoid wear on the bottom of the storage tank. The side of the grinding disk 24 is covered by the fixed frame 29 to prevent the polishing paste from splashing around as the grinding disk 24 rotates after the polishing paste is applied. When polishing the bottom of the inner wall of the storage tank, the fixed frame 29 contacts the bottom of the storage tank and stops moving, and drives the sliding shaft 26 to slide in the connecting plate 25, pressing the second spring 28. At this time, as the slider 7 moves downward, the grinding disk 24 contacts the bottom of the storage tank, thereby polishing the bottom of the inner wall of the storage tank. Before polishing the storage tank, the first motor 5 is used to control the grinding disk 24 to move toward the bottom of the inner wall of the storage tank, and the fixed frame 29 continues to contact the bottom of the storage tank after it contacts the bottom of the storage tank. The grinding disc 24 is controlled to move downward, and the pull rod 41 is moved downward by extrusion, driving the piston plate 40 to move downward. With the cooperation of the two one-way valves 38, the gas in the sleeve 39 is discharged. Then, the grinding disc 24 is controlled to move upward. Under the action of the second spring 28, the fixing frame 29 is moved upward and reset. Under the pulling of the fixing frame 29, the pull rod 41 is driven to move upward, and the piston plate 40 is moved upward. With the cooperation of the two one-way valves 38, the polishing paste in the cavity 35 can be drawn into the sleeve 39 along the pipe 37. Then, the grinding disc 24 is controlled to move downward again, and the piston plate 40 is driven to move downward in the same way. With the cooperation of the two one-way valves 38, the polishing paste in the sleeve 39 can be squeezed into the extrusion chamber 36 along the pipe 37.The polishing paste is allowed to flow along the inner wall of the extrusion chamber 36 to increase the coverage area of ​​the polishing paste, and then the polishing paste is squeezed out from several discharge ports 42, thereby evenly applying a layer of polishing paste on the grinding disc 24 to prevent the polishing paste from piling up and being easily thrown off by the grinding disc 24. In this way, each time the grinding disc 24 is controlled to grind the bottom of the inner wall of the storage tank, polishing paste can be added to the grinding disc 24 once. When the grinding disc 24 is controlled to be close to the inner wall of the storage tank, the two second side plates 32 first contact the inner wall of the storage tank. Under the extrusion of the storage tank, the two second side plates 32 slide in the two first side plates 30 at the same time, pressing the two third springs 31. Therefore, after the grinding disc 24 is close to the inner wall of the storage tank, the two second side plates 32 are close to the inner wall of the storage tank, and the two first side plates 30 cooperate with the two second side plates 32 to block both sides of the grinding disc 24 to prevent the polishing paste from The polishing paste is thrown out to the side, so that the polishing paste is concentrated on the grinding disc 24, and the polishing effect of the grinding disc 24 is improved. When grinding the angle at the bottom of the inner wall of the storage tank, the grinding disc 24 is controlled to move toward the angle at the bottom of the inner wall of the storage tank. Under the action of the fourth spring 45, the grinding block 46 first contacts the angle at the bottom of the inner wall of the storage tank, and then the grinding disc 24 is controlled to move. Under the extrusion of the storage tank, the slide bar 44 slides in the grinding disc 24, and the fourth spring 45 is pressed. Therefore, when the grinding disc 24 rotates, under the reaction force of the fourth spring 45, the grinding block 46 is always close to the angle at the bottom of the inner wall of the storage tank, and the polishing paste falling from the grinding disc 24 falls on the grinding block 46, slides down along the inclined surface of the top of the grinding block 46, and flows downward through the discharge trough 47, adding polishing paste to the joint between the grinding block 46 and the angle of the storage tank, thereby improving the polishing effect of the angle of the storage tank.
