Description

Technical Field

[0001] This invention relates to the field of urea barrel production and processing technology, and in particular to a processing equipment for producing automotive urea barrels. Background Technology

[0002] Urea containers are devices used to store and supply urea solution in automotive urea reduction catalyst systems. The urea solution is primarily used in these systems to reduce nitrogen oxides in exhaust gases, thereby reducing environmental pollution from vehicle emissions. Currently, the main manufacturing method for urea containers is injection molding. However, because the cavity of the injection mold cannot be completely sealed, and the opening and bottom of the urea container are located at the connection points of the cavity during injection molding, burrs are easily generated.

[0003] Regarding burrs on urea containers, it is usually necessary to trim the burrs at the container opening and bottom to prevent them from affecting the sealing performance and the effectiveness of the product. With the development of technology, technicians in related fields have also made a lot of optimizations to the processing of automotive urea containers. For a more accurate comparison, Chinese patent CN211842869U discloses a urea container production device, including a base and two support grooves. The two support grooves are fixed to the upper ends of the middle two sides of the base. The upper end of the base is supported and fixed to an upper beam by a support beam. An electro-hydraulic push rod is fixed below the upper beam between the two support grooves, and a pressure groove is fixed to the bottom of the electro-hydraulic push rod. Cutting tools are fixed below the upper beam on both sides of the electro-hydraulic push rod by spring ropes, and there are two cutting tools.

[0004] When in use, the injection-molded urea bucket is placed above the support grooves on both sides. Then, by operating the control switch, the electro-hydraulic actuator moves the pressure groove downward to press against the upper end of the urea bucket, thus clamping and fixing the urea bucket. Then, the cutter fixed at the bottom of the spring rope can be easily taken from both sides. After that, the cutter can be quickly used to cut off the corner of the urea bucket. After the cutting is completed, the electro-hydraulic actuator moves the pressure groove upward to remove the cut urea bucket, and then the subsequent processing operations can continue.

[0005] However, the above-mentioned urea barrel production device has some shortcomings in actual use:

[0006] 1. Manual placement of urea barrels is required to secure them. This method is inefficient, cannot be automated to transport and hold the barrels, and poses a risk of injury during manual placement. Furthermore, manual trimming of excess material from the barrels is necessary. While a cutter is attached via a spring rope for easy access, it cannot be automatically trimmed, resulting in low efficiency. Additionally, manual trimming cannot maintain precision and may scratch the barrels, increasing defect and scrap rates and reducing costs.

[0007] 2. Because manual cutting of urea barrels generates waste, which cannot be collected, the waste easily falls into the urea barrel. This waste can contaminate the urea subsequently poured into the barrel, thus affecting the purity of the urea.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing methods for removing burrs from urea tanks. Summary of the Invention

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] I. This invention, through the cooperation of an automatic feeding device, a clamping device, and a cutting device, can control the automatic supply, automatic clamping and feeding, automatic cutting, and automatic collection of cutting waste of the urea tank to achieve continuous operation. In addition, when the urea tank passes through the guide plate, the guide plate can straighten the urea tank, and the urea tank can be positioned by contacting the baffle, so that the urea tank is located below the cutting device.

[0022] Second, the distance between the two first clamping plates and the distance between the two second clamping plates in the cutting device provided by the present invention can be adaptively adjusted according to the width and thickness of the urea barrel, so as to be able to clamp urea barrels of different models; the clamping of the urea barrel by the first clamping plate and the second clamping plate can ensure that it remains stable during the cutting process, avoid the urea barrel from tilting due to lack of stability and thus avoid processing errors, thereby improving the cutting efficiency and quality of the cutting device for the urea barrel.

[0023] Third, this invention removes burrs from the mouth and bottom of the urea barrel using a cutting device, while simultaneously recycling the cutting and grinding waste using a recycling device. This prevents waste from falling into the urea barrel and contaminating it, thus affecting the purity of the urea. Furthermore, by adjusting the distance between the scrapers on the two support plates, urea barrels of different thicknesses can be trimmed, making it applicable to different models of urea barrels and highly adaptable.

[0024] Fourth, the present invention provides an upward supporting force to the actuator block through the cooperation between the pull rod and the annular groove at the bottom of the slider, and can maintain the balance and stability of the actuator block; the T-block without the cutting plate acts as a counterweight to prevent the actuator block from shaking due to excessive weight deviation on both sides during rotation, thereby avoiding damage to the mouth of the urea tank caused by the actuator block driving the cutting plate.

[0038] The following is in conjunction with the appendix Figures 1-11 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0039] This application discloses a processing equipment for producing automotive urea cans. The equipment is primarily used in the production of urea cans. Technically, it allows urea cans to be conveyed by an automatic feeding device 5 and clamped and fixed by a clamping device 7. Subsequently, a cutting device 9 removes and polishes burrs from the can's opening and bottom. Particularly during the fixing process, the clamping device 7 can adjust and fix the position of the urea can, and can also hold the can't move it up or down to coordinate with the cutting device 9, effectively improving efficiency. Furthermore, this processing equipment can also control the cutting and polishing of the openings of urea cans of different thicknesses and diameters by adjusting the cutting device 9, thus enabling the production and processing of various types of urea cans.

[0040] Example 1:

[0041] Reference Figure 1 As shown, a processing equipment for producing automotive urea barrels includes a chassis 1, a working chamber 2 inside the chassis 1, a cutting device 9 installed on the top wall of the working chamber 2, two hanging plates 3 symmetrically installed on the top wall of the working chamber 2, a single hydraulic cylinder 4 installed at the lower end of the hanging plate 3, a clamping device 7 installed at the bottom of the single hydraulic cylinder 4, and an automatic feeding device 5 installed at the bottom of the working chamber 2.

[0042] In the specific implementation process, the urea barrel first enters the working chamber 2 through the automatic feeding device 5. Then, the single hydraulic cylinder 4 controls the clamping device 7 to descend and clamp the urea barrel. Subsequently, the single hydraulic cylinder 4 drives the clamping device 7 and the urea barrel to rise to the designated height. Then, the cutting device 9 cuts and polishes the burrs at the mouth and bottom of the urea barrel.

[0043] Reference Figure 3 and Figure 4As shown, in order to facilitate the cutting of burrs at the mouth and bottom of the urea barrel, the urea barrel needs to be transported to the bottom of the cutting device 9 and fixed thereon. Based on this, a clamping device 7 is provided in this embodiment. Specifically, the clamping device 7 includes a load plate 71 installed at the bottom of the single hydraulic cylinder 4. Two sliding plates 72 are symmetrically installed at the bottom of the load plate 71 along the single hydraulic cylinder 4, and a protrusion 73 that cooperates with the sliding plate 72 is installed at the bottom of the load plate 71. A first clamping plate 74 is installed at the bottom of the two sliding plates 72 along the width direction. The first clamping plate 74 is installed at the bottom of the two sliding plates 72 at the lower end of the same load plate 71. Plate 74, the length direction of the first clamping plate 74 is parallel to the length direction of the load plate 71. Two square holes 75 are symmetrically opened on the first clamping plate 74 along the length direction, and the square holes 75 of the two first clamping plates 74 are staggered. Gears 76 are rotatably installed on the upper and lower side walls of the square holes 75 through a rotating shaft. A first rack 77 is slidably installed in the square hole 75 along the opening direction. The first rack 77 meshes with the gear 76, and the first rack 77 in the square hole 75 of one of the first clamping plates 74 is connected to the other first clamping plate 74. The first rack 77 is arranged perpendicularly to both first clamping plates 74.

[0044] In the specific implementation process, firstly, the urea barrel is transported to the designated position inside the working chamber 2 by the automatic feeding device 5. Secondly, the single-section hydraulic cylinder 4 is activated to push the load plate 71 downward. After reaching the designated position, it stops. Then, the second motor 79 is activated. The second motor 79 drives the gear 76 to rotate counterclockwise. The gear 76 drives the first rack 77 near the connecting plate 103 to move horizontally in the direction of rotation of the second motor 79. The rack pulls the first clamping plate 74 connected to it to move synchronously. The first clamping plate 74 drives the first rack 77 and the gear 76 on it to move synchronously. The gear 76 on it rotates clockwise and drives the first rack 77 that is engaged with the gear 76 to move in the opposite direction to the first clamping plate 74. The first rack 77 pulls the first clamping plate 74 connected to it to move synchronously, thereby controlling the relative movement of the two first clamping plates 74.

[0045] Reference Figures 1 to 3As shown, in order to facilitate continuous trimming during the production and processing of urea barrels, the urea barrels need to be transported to the cutting device 9 for trimming. Based on this, an automatic feeding device 5 is provided in this embodiment. Specifically, the automatic feeding device 5 includes four support blocks 51 installed below the machine housing 1 and symmetrically arranged along its length and width. Each pair of support blocks 51 on both sides of the machine housing 1 is rotatably connected to a drive shaft 52 on opposite sides. The outer walls of the two drive shafts 52 are symmetrically fitted with a conveyor belt 53 along their length. The automatic feeding device also includes a conveyor belt 53 along the conveyor belt 53. Two support frames 54 are symmetrically arranged in the width direction. The support frames 54 are located on the side of the machine box 1 away from the direction of movement of the conveyor belt 53. Guide plates 55 are installed on opposite sides of the two support frames 54. Pulleys 56 are installed on opposite sides of the two hanging plates 3 near the middle of the working chamber 2 through positioning frames. Ropes 57 are connected to the upper end of the load plate 71. The ends of the two ropes 57 away from the load plate 71 pass through the pulleys 56 above them and are connected to a baffle 58. Two telescopic rods 59 are symmetrically installed on the upper end of the baffle 58. The ends of the telescopic rods 59 away from the baffle 58 are connected to the inner top wall of the working chamber 2.

[0046] Furthermore, to ensure that the urea tank remains vertical and centered when entering the working chamber, in this embodiment, the guide plate 55 is composed of a vertical plate 60, a combing plate 61, and a guide plate 62. The vertical plate 60 is installed on the opposite side of the two support frames 54. The guide plate 62 is installed on the side of the vertical plate 60 away from the direction of movement of the conveyor belt 53 via the combing plate 61. The distance between the two combing plates 61 is less than the width of the conveyor belt 53. The guide plate 62 gradually tilts away from the side of the conveyor belt.

[0047] It should be noted that an external intermittent motor (not shown in the figure) is mounted on any of the support blocks 51, and the drive shaft 52 on the support block 51 is connected to the output shaft of the intermittent motor; in addition, the conveyor belt 53 consists of two sections arranged along its width, and a gap is left between the two sections of the conveyor belt 53 for the cutting device 9 to cut the burrs on the bottom of the urea tank (in Figure 2 (as shown in the image).

[0048] In the initial state, the load plate 71 is at its highest position under the action of the single hydraulic cylinder 4. At this time, the baffle 58 is not under the tension of the rope 57 and descends to its lowest position under its own gravity.

[0049] In the specific implementation process, firstly, the external intermittent motor is started. The intermittent motor drives the conveyor belt 53 to perform intermittent circumferential motion through the transmission shaft 52. Then, the urea barrel is placed vertically on the upper end of the conveyor belt 53, with one end of the urea barrel opening facing one side of the machine box 1. The conveyor belt 53 drives the urea barrel to move intermittently towards the machine box 1. When the urea barrel passes the guide plate 55, the guide plate 62 applies a pushing force to the urea barrel and guides the urea barrel into the space between the two combing plates 61, thereby straightening the urea barrel through the combing plates 61.

[0050] The conveyor belt 53 carries the urea tank into the working chamber 2. After the urea tank comes into contact with the baffle 58, the intermittent motor controls the conveyor belt 53 to stop moving, and the single hydraulic cylinder 4 drives the first clamp 74 of the load plate 71 to descend. The load plate 71 applies a pulling force to the baffle 58 through the cooperation between the rope 57 and the pulley 56, so that the baffle 58 rises due to the pulling force of the rope 57. The telescopic rod 59 retracts due to the pushing force of the baffle 58 and always plays a limiting role on the baffle 58, so that the baffle 58 can only move in a straight line up and down.

[0051] Subsequently, the load plate 71 clamps the urea barrel through the first clamping plate 74 and rises synchronously. Then, the cutting device 9 cuts and grinds the urea barrel, while the baffle 58 returns to its initial state. After the cutting and grinding are completed, the single hydraulic cylinder 4 drives the load plate 71, the first clamping plate 74 and the urea barrel to descend as a whole and place them back on the upper end of the conveyor belt 53. Then, the first clamping plate 74 releases its grip on the urea barrel and rises under the action of the load plate 71 while controlling the baffle 58 to descend. When the baffle 58 can no longer contact the urea barrel, the conveyor belt 53 moves the urea barrel out of the working chamber 2. During this period, the intermittent motor drives the conveyor belt 53 to move the repaired urea barrel out of the working chamber 2 and transport the unrepaired urea barrel into the working chamber 2 to achieve the purpose of continuous operation.

[0052] Reference Figures 3 to 5As shown, to facilitate the cutting and grinding of the urea barrel in the center of the working chamber 2, this embodiment provides a clamping device 7. The clamping device 7 also includes two limiting clips 78 symmetrically installed on both side walls along the thickness direction of the first clamping plate 74, and the limiting clips 78 are located outside the square hole 75. A second motor 79 is installed on the upper end of one of the first clamping plates 74 above the square hole 75 through a motor cover. The output shaft of the second motor 79 is connected to a gear 76 inside the square hole 75. Two opposing second racks 80 are slidably connected in the two limiting clips 78 outside the same square hole 75 along the length direction of the first clamping plate 74, and the second racks 80 pass through the limiting clips 78 and mesh with the gears 76. A second clamping plate 81 is provided at one end of each of the two second racks 80 on opposite sides of the two first clamping plates 74 and at the other end of each of the two second racks 80 on opposite sides. The two second clamping plates 81 are symmetrically arranged along the length of the first clamping plates 74 and are arranged perpendicular to the first clamping plates 74. Multiple spring rods 82 are installed in the middle of the opposite sides of the second clamping plates 81. An auxiliary clamping plate 83 is installed on the opposite sides of the multiple spring rods 82. The spring rods 82 always apply a pushing force to the auxiliary clamping plate 83, so that the distance between the auxiliary clamping plate 83 and the second clamping plate 81 is maximized in the initial state, and the distance between the auxiliary clamping plate 83 and the second clamping plate 81 is greater than the distance between the first rack 77 and the second clamping plate 81.

[0053] In the specific implementation process, as the gear 76 rotates, it drives the two second racks 80 meshing with it to move in opposite directions. The two second racks 80 drive the second clamping plates 81 connected to them to move in opposite directions. Thus, while the two first clamping plates 74 move relative to each other, the two second clamping plates 81 can also move relative to each other. Therefore, the urea barrel can be clamped by the two first clamping plates 74 and the two second clamping plates 81 moving simultaneously. The distance between the two first clamping plates 74 and the distance between the two second clamping plates 81 can be adaptively adjusted according to the width and thickness of the urea barrel, so that different types of urea barrels can be clamped, so that the cutting device 9 can trim them.

[0054] Two first clamping plates 74 move towards each other to clamp the urea barrel, pushing it during the clamping process to ensure it is directly below the adjusting plate 92. Simultaneously, as the two second clamping plates 81 move towards each other, they drive the spring rod 82 and auxiliary clamping plate 83 to move synchronously. The auxiliary clamping plate 83 pushes the urea barrel, positioning it so that it is in the middle of the first clamping plates 74, ensuring that the barrel opening is below the cutting plate 101. After clamping the urea barrel, a single hydraulic rod lifts the urea barrel through the load plate 71, positioning the barrel opening at the bottom of the cutting device 9. The cutting device 9 then cuts and polishes the burrs at the barrel opening and bottom. The clamping of the urea barrel by the first clamping plates 74 and the second clamping plates 81 ensures its stability during the cutting process, preventing the barrel from tilting due to instability and causing processing errors, thereby improving the cutting efficiency and quality of the urea barrel by the cutting device 9.

[0055] After cutting and grinding are completed, the single-section hydraulic cylinder 4 pushes the load plate 71 down. When it reaches the designated height, the second motor 79 is started. The second motor 79 drives the gear 76 to rotate clockwise. During the rotation of the gear 76, the first rack 77 and the second rack 80 on its outside respectively drive the two first clamping plates 74 and the two second clamping plates 81 to move in opposite directions, thereby releasing the clamping of the urea barrel by the first clamping plates 74 and the second clamping plates 81 and placing the urea barrel back onto the conveyor belt 53. Then, the single-section hydraulic cylinder 4 drives the load plate 71, the first clamping plates 74 and the second clamping plates 81 to rise again, so that the conveyor belt 53 carries the urea barrel out of the working chamber 2.

[0056] Reference Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, burrs are generated on urea barrels during the production process, which affects their appearance and may scratch the skin. Furthermore, burrs at the barrel opening can prevent the lid from closing properly, affecting the barrel's seal and potentially causing urea leakage or allowing external air to enter, thus affecting the urea's purity. To address this issue, this embodiment provides a cutting device 9 capable of removing and polishing burrs on urea barrels. Specifically, the cutting device 9 includes a fixed column 91 installed on the top wall of the working chamber 2, with an adjusting plate 92 installed at the lower end of the fixed column 91. The bottom of the section plate 92 is provided with a T-slot 93, and a slider 94 is slidably connected in the T-slot 93. A first motor 95 is installed at the bottom of the slider 94. An execution block 96 is sleeved on the output shaft of the first motor 95. Two T-blocks 97 are installed at the bottom of the execution block 96, and a balancing mechanism 98 is installed between the execution block 96 and the slider 94. Two connecting plates 99 are symmetrically installed at the bottom of one of the T-blocks 97. A second bidirectional lead screw 109 is rotatably passed between the two connecting plates 99. A cutting plate 101 is provided between the connecting plate 99 and the T-block 97. The cutting device 9 also includes a recovery mechanism 102.

[0057] It should be noted that in this embodiment, a limiting member (not shown in the figure) is provided between the slider 94 and the T-slot 93. When the slider 94 slides along the T-slot 93, it can be automatically locked under the action of the limiting member, thereby preventing the slider 94 from moving randomly and causing the execution block 96 and the cutting plate 101 at its lower end to shift, thereby preventing the shift of the cutting plate 101 from causing scratches on the mouth of the urea barrel.

[0058] Furthermore, in this embodiment, the cutting device 9 also includes a connecting plate 103 installed at one end of the load plate 71. Multiple hydraulic cylinders 104 are installed at the bottom of the connecting plate 103 near the second clamping plate 81. Through the setting of the connecting plate 103, the multiple hydraulic cylinders 104 can be synchronously raised and lowered by the connecting plate 103 during the up and down movement of the load plate 71. A reinforcing plate 105 is installed at the end of the multiple hydraulic cylinders 104. The reinforcing plate 105 is connected to the mounting plate 106 by bolts. The end of the mounting plate 106 away from the multiple hydraulic cylinders 104 is connected to the cutting blade 107 by bolts. An anti-slip mechanism 108 is provided between the reinforcing plate 105, the mounting plate 106 and the cutting blade 107.

[0059] Reference Figure 7 and Figure 9As shown, in order to prevent the cutting plate 101 from tilting due to lack of stability during the cutting of the urea tank, a balancing mechanism 98 is provided in this embodiment to maintain its balance. Specifically, the balancing mechanism 98 includes two pull rods 981 installed on the upper end of the execution block 96. The upper end of the pull rods 981 is connected to the slider 94. The lower end of the slider 94 is provided with an annular groove 982. Two pull rods 981 that cooperate with the annular groove 982 are symmetrically installed on the upper end of the execution block 96. Two receiving grooves 983 are symmetrically opened at the bottom of the execution block 96. T-shaped blocks 97 slide and dock in the receiving grooves 983. The execution block 96 is symmetrically rotated along the width direction and connected to two first bidirectional lead screws 100 that pass through the receiving grooves 983 and the T-shaped blocks 97. The same end of the two first bidirectional lead screws 100 is connected by a belt 984, and the T-shaped blocks 97 are sleeved on the outer wall of the first bidirectional lead screws 100 by a threaded connection.

[0060] In the specific implementation process, before cutting the urea barrel, the slider 94 is adjusted to the designated position according to the barrel opening position of different models of urea barrels. Then, the first bidirectional lead screw 100 is rotated so that the distance between the two T-blocks 97 is equal to the diameter of the urea barrel opening. Then, the cutting blade 107 and the mounting plate 106 are adjusted by the anti-slip mechanism 108 to achieve the purpose of making the cutting blade 107 flush with the bottom surface of the vehicle-mounted urea barrel. Then, the clamping device 7 drives the urea barrel to rise, so that the barrel opening of the urea barrel contacts the cutting plate 101. Then, the first motor 95 is started, and the first motor 95 drives the actuator 96 to rotate. The sliding block 96 drives the T-block 97 and the cutting plate 101 to perform a circular motion, thereby controlling the cutting plate 101 to move circumferentially along the opening of the urea barrel and to cut and grind the opening. At the same time, the multi-section hydraulic cylinder 104 is activated, which drives the cutting blade 107 to move along the width of the automotive urea barrel and to cut the burrs on the bottom. While the burrs at the opening and bottom of the urea barrel are being removed, the waste material from cutting and grinding is sucked into the storage box 115 through the recycling device to prevent the waste material at the opening of the urea barrel from falling into the inside and causing urea contamination, which would affect the purity of the urea.

[0061] As the actuator 96 rotates, it drives the upper pull rod 981 to rotate synchronously. The interaction between the pull rod 981 and the annular groove 982 at the bottom of the slider 94 provides an upward supporting force to the actuator 96 and maintains the balance and stability of the actuator 96. The T-shaped block 97 without the cutting plate 101 acts as a counterweight to prevent the actuator 96 from shaking due to excessive weight deviation on both sides during rotation, thereby avoiding damage to the opening of the urea tank caused by the actuator 96 driving the cutting plate 101.

[0062] Reference Figure 8As shown, during the injection molding process of urea barrels, burrs may appear on the inner, outer, and upper sides of the barrel opening, and the thickness of the barrel opening is uneven. If only horizontal cutting is used, it is easy to cause the burrs to be not cleaned properly. Therefore, a cutting plate 101 is provided in this embodiment. Specifically, the cutting plate 101 includes a support plate 110 that is threadedly sleeved on the outer wall of the second bidirectional lead screw 109 and located inside the two connecting plates 99. Two fixing plates 111 are symmetrically installed at the bottom of the T-shaped block 97 along the length direction of the second bidirectional lead screw 109. Two scrapers 112 and a grinding disc 113 are provided on the opposite side of the support plate 110 and at the lower end of the fixing plate 111. The scrapers 112 are symmetrically arranged along the grinding disc 113 and inclined to the side away from the grinding disc 113. The thickness of the grinding disc 113 is greater than the width of the scraper 112. The support plate 110 is provided with mating holes 114 for the scrapers 112 and the grinding disc 113 on the fixing plate 111 to pass through.

[0063] In the specific implementation process, before cutting the urea barrel, the second bidirectional lead screw 109 is rotated to adjust the distance between the scrapers 112 on the two support plates 110 to be the same as the thickness of the urea barrel opening. Then, the urea barrel rises under the action of the clamping device 7, and the opening of the urea barrel is inserted between the two support plates 110. The upper end of the urea barrel opening abuts against the lower end of the scraper 112 at the bottom of the fixed plate 111. During the cutting process, the scrapers 112 on the support plates 110 cut the inner and outer sides of the urea barrel opening, while the scrapers 112 on the fixed plate 111 cut the top of the urea barrel opening. Then, the grinding disc 113 grinds the cut opening. This achieves the purpose of cutting and grinding the urea barrel opening. By adjusting the distance between the scrapers 112 on the two support plates 110, urea barrels of different thicknesses can be trimmed, thus making it applicable to different models of urea barrels and highly adaptable.

[0064] Reference Figure 10 As shown, during the cutting process of the bottom of the urea tank, the cutting blade 107 is subjected to thrust for a long time. If it is only connected by bolts, the cutting blade 107 may tilt, which will prevent the cutting blade 107 from completely removing the burrs at the bottom of the urea tank. If the cutting blade 107 tilts in the opposite direction, it may easily scratch the urea tank. In order to solve this problem, an anti-slip mechanism 108 is provided in this embodiment. Specifically, the anti-slip mechanism 108 includes an anti-slip rack 121. Multiple annularly distributed anti-slip racks 121 are provided at the connection between the mounting plate 106 and the cutting blade 107 and at the connection between the mounting plate 106 and the reinforcing plate 105. Multiple anti-slip grooves 122 that cooperate with the anti-slip racks 121 are provided at the connection between the mounting plate 106 and the cutting blade 107 and at the connection between the mounting plate 106 and the reinforcing plate 105.

[0065] During the adjustment of the cutting blade 107, the bolt connection between the cutting blade 107 and the mounting plate 106 is first released. At this time, the angle between the cutting blade 107 and the mounting plate 106 can be adjusted by rotation. After the adjustment is completed, the bolt connection is restored. At this time, the anti-slip rack 121 engages with the anti-slip groove 122, thereby improving the stability of the cutting blade 107 and preventing the cutting blade 107 from tilting arbitrarily due to force, so as to prevent the cutting blade 107 from tilting.

[0066] Example 2:

[0067] Reference Figure 9 and Figure 11 As shown in Embodiment 1, waste generated during the cutting and grinding process may fall into the urea tank through the opening, causing contamination of the urea during subsequent filling and affecting its purity. Furthermore, the waste has some value and can be recycled. Therefore, this embodiment provides a recycling mechanism 102. Specifically, the recycling mechanism 102 includes a storage box 115 installed on the top wall of the working chamber 2. A vacuum pump 116 is installed at the bottom of the storage box 115, connected to a connecting pipe 117. A first collection hopper 118 with a top opening is installed at the bottom of the cutting blade 107. The closed end of the first collection hopper 118 is connected to the connecting pipe 117. A second collection hopper 119 is installed at the lower end of the support plate 110. The two second collection hoppers 119 have openings on opposite sides, and the closed end of the second collection hopper 119 is connected to the connecting pipe 117 via a collection pipe 120.

[0068] In the specific implementation process, before cutting the urea barrel, the vacuum pump 116 is started. The waste generated by the cutting blade 107 during the cutting process is sucked into the connecting pipe 117 through the first collection hopper 118, and then enters the storage box 115 through the connecting pipe 117. This avoids the waste from accumulating on the conveyor belt 53, which would cause the urea barrel to become unstable and tip over or fall during the conveyor belt 53's transport of the urea barrel. Moreover, the fallen waste needs to be cleaned manually, increasing the workload. The waste generated by the scraper 112 and grinding disc 113 on the bearing plate 110 during the cutting process of the urea barrel will enter the collection pipe 120 through the second collection hopper 119. The waste enters the connecting pipe 117 through the collection pipe 120, and finally enters the storage box 115. This achieves the purpose of cleaning the cutting waste, preventing the waste at the mouth of the urea barrel from falling into its interior and causing urea contamination, which would affect the purity of the urea. It also allows for the recycling and reuse of waste, thus saving resources and energy.

[0069] During operation: First step: Start the external intermittent motor. The intermittent motor drives the conveyor belt 53 to perform intermittent circumferential motion through the drive shaft 52. Then, place the urea tank vertically on the upper end of the conveyor belt 53. The conveyor belt 53 drives the urea tank to move intermittently towards the machine box 1. When the urea tank passes the guide plate 55, the guide plate 55 straightens the urea tank. The conveyor belt 53 continues to drive the urea tank into the working chamber 2. After the urea tank comes into contact with the baffle 58, the conveyor belt 53 stops moving.

[0070] Step 2: Start the single hydraulic cylinder 4. The single hydraulic cylinder 4 drives the clamping device 7 connected to the load plate 71 to descend. The load plate 71 applies a pulling force to the baffle 58 through the cooperation between the rope 57 and the pulley 56, so that the baffle 58 rises due to the pulling force of the rope 57. The single hydraulic cylinder 4 controls the clamping device 7 to stop descending to the designated position.

[0071] Then, the second motor 79 is started, which drives the gear 76 to rotate counterclockwise. During the rotation of the gear 76, the first rack 77 and the second rack 80 on its outside drive the two first clamping plates 74 and the two second clamping plates 81 to move towards each other. Thus, the urea barrel is clamped by the first clamping plates 74 and the second clamping plates 81, and the urea barrel is picked up. Then, the single hydraulic cylinder 4 drives the first clamping plate 74, the second clamping plate 81 and the urea barrel to rise as a whole. At the same time, the baffle 58 returns to its initial state and stops rising when the mouth of the urea barrel contacts the cutting plate 101.

[0072] Step 3: Start the first motor 95. The first motor 95 drives the actuator 96 to rotate. The actuator 96 drives the T-block 97, scraper 112 and grinding disc 113 to move in a circular motion as a whole, thereby controlling the scraper 112 and grinding disc 113 to move circumferentially along the opening of the urea barrel and to cut and grind the opening of the barrel. At the same time, start the multi-section hydraulic cylinder 104. The multi-section hydraulic cylinder 104 drives the cutting blade 107 to move along the width direction of the vehicle urea barrel and to cut the burrs on the bottom. While the burrs at the opening and bottom of the urea barrel are removed, the waste material from cutting and grinding is sucked into the storage tank 115 through the recycling device to prevent the waste material at the opening of the urea barrel from falling into the inside and causing urea contamination, which would affect the purity of the urea.

[0073] Step 4: After cutting and grinding, the single hydraulic cylinder 4 pushes the load plate 71 down. When it reaches the designated height, the second motor 79 is started. The second motor 79 drives the gear 76 to rotate clockwise. During the rotation of the gear 76, the first rack 77 and the second rack 80 on its outside drive the two first clamping plates 74 and the two second clamping plates 81 to move in opposite directions, thereby releasing the clamping of the urea barrel by the first clamping plates 74 and the second clamping plates 81. Under the action of the load plate 71, the gear 76 rises while controlling the baffle 58 to descend. When the baffle 58 can no longer contact the urea barrel, the conveyor belt 53 moves the urea barrel out of the working chamber 2. During this period, the intermittent motor drives the conveyor belt 53 to move the finished urea barrel out of the working chamber 2 and transport the unfinished urea barrel into the working chamber 2 to achieve the purpose of continuous operation.

[0074] Step 5: Repeat the above steps to achieve automatic cutting and polishing of multiple urea barrels.
