Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and in particular to a steel plate cutting device for the production of large milk tanks. Background Technology

[0002] In the dairy processing industry, large milk tanks are key storage equipment. Their bodies are mostly made of stainless steel plates through rolling and welding. The cutting precision of the steel plates directly determines the tank's sealing performance and structural strength. Currently, the industry mainly uses two cutting methods: one is traditional manual flame cutting, which relies on the operator's experience, often resulting in cutting errors of ±2mm or more, and significant thermal deformation, requiring extensive subsequent grinding and correction, making the process cumbersome; the other is CNC plasma cutting equipment, which, although offering improved precision, requires multiple adjustments to the plate position when cutting steel plates for large tanks with diameters of 3-5m, limiting the single cutting range and making it unsuitable for continuous cutting of curved or irregularly shaped tank plates.

[0003] As dairy companies expand to a larger scale, the demand for single-tank capacity has increased to 50-100m³, further raising the requirements for the efficiency and precision of steel plate cutting.

[0004] The existing technology has the following shortcomings: the existing equipment has problems such as low cutting efficiency, low cutting efficiency due to the large tank size, low degree of automation, and the need for a large number of workers to work together, which makes it difficult to meet the continuous production requirements of modern production lines. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a steel plate cutting device for the production of large milk tanks.

[0007] As a preferred technical solution of the present invention, the plate clamping and adjusting mechanism includes a fixed seat fixedly installed on the upper end of the adjusting platform, an adjusting cylinder fixedly installed on the upper end of the fixed seat, a horizontal connecting plate fixedly installed on the output end of the adjusting cylinder, a guide shaft fixedly installed on the rear surface of the horizontal connecting plate, the guide shaft passing through the fixed seat, and a clamping plate fixedly installed on the upper end of the front surface of the horizontal connecting plate.

[0008] As a preferred technical solution of the present invention, three sliding grooves arranged at equal angles are provided on one side surface of the clamping disk, and a clamping plate is slidably installed in each sliding groove. Three control motors corresponding to the sliding grooves are fixedly installed on the outer surface of the clamping disk.

[0009] As a preferred technical solution of the present invention, the plate limiting mechanism includes a cylinder seat fixedly installed on the upper end of the positioning support, a propulsion cylinder fixedly installed on the upper end of the cylinder seat, a limiting plate fixedly installed through the cylinder seat at the output end of the propulsion cylinder, and symmetrical limiting shafts fixedly installed on the rear surface of the limiting plate.

[0010] As a preferred technical solution of the present invention, the plate rotation mechanism includes a rotating motor fixedly installed on the outside of the drive housing, a drive gear fixedly installed at the output end of the rotating motor, and drive cams rotatably installed on both sides of the drive gear inside the drive housing, and a follower gear meshing with the drive gear is fixedly installed on one side surface of each drive cam.

[0011] As a preferred technical solution of the present invention, the plate cutting mechanism includes a drive motor fixedly installed on the rear surface of the slide table, the output end of the drive motor rotatably mounted on the slide table, a symmetrical slider fixedly installed on the lower surface of the slide table, and a telescopic motor fixedly installed on the upper end of the boss, the output end of the telescopic motor penetrating the lower end of the slide table.

[0012] As a preferred technical solution of the present invention, the clamping mechanism further includes clamping supports symmetrically fixedly installed on the upper surface of the base, and a clamping motor is fixedly installed on the rear surface of each clamping support, and a rotating arm is rotatably installed on one side of the clamping motor.

[0013] As a preferred embodiment of the present invention, a pressure arm is fixedly installed at the upper end of the rotating arm, an adjustable telescopic rod is fixedly installed on one side of the upper surface of the pressure arm, and a pressure block is fixedly installed at the output end of the adjustable telescopic rod.

[0014] As a preferred technical solution of the present invention, symmetrical support seats are fixedly installed on the upper surface of the base, and a support pad is fixedly installed on the upper end of each support seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The plate clamping and adjusting mechanism of this invention is equipped with three sliding clamping plates arranged at equal angles and a control motor, which can stably clamp the steel plate and accurately adjust its position. The guide shaft and adjusting cylinder further ensure the stability of the adjusting distance. On the other hand, the plate rotation mechanism drives the drive cam to rotate by the meshing of the drive gear and the follower gear, which can drive the steel plate to rotate smoothly. Combined with the design of the telescopic motor controlling the sliding of the slide table and the drive motor driving the rotation of the cutting blade in the plate cutting mechanism, it can realize the continuous cutting of arc-shaped and irregularly shaped can body plates, avoid the accuracy deviation caused by multiple adjustments, and the cutting error can be greatly reduced, meeting the high requirements of 50-100m³ large milk tanks for tank sealing and structural strength.

[0016] 2. This device features an optimized, fully automated structural design. The plate-limiting mechanism uses a propulsion cylinder to automatically position the steel plate against the limiting plate and limiting shaft. The clamping mechanism, driven by a clamping motor, automatically clamps the steel plate using a rotating arm, a pressure arm, an adjustable telescopic rod, and a pressure block, eliminating the need for manual fixing. Simultaneously, the plate's adjustment, rotation, and cutting actions are all driven by motors and cylinders, requiring minimal manual intervention. This design reduces the number of operators, lowers labor costs, and eliminates tedious manual adjustments and fixing processes. The daily plate cutting capacity far exceeds the 2-3 sets of existing devices, significantly improving cutting efficiency and meeting the continuous production needs of modern production lines.

[0022] The clamping disk 304 has three equally spaced grooves 307 on one side surface. Each groove 307 is slidably mounted with a clamping plate 306, and three control motors 305 corresponding to the grooves 307 are fixedly mounted on the outer surface of the clamping disk 304.

[0023] The plate limiting mechanism includes a cylinder seat 601 fixedly installed on the upper end of the positioning support 6. A propulsion cylinder 602 is fixedly installed on the upper end of the cylinder seat 601. A limiting plate 604 is fixedly installed through the cylinder seat 601 at the output end of the propulsion cylinder 602.

[0025] The sheet metal cutting mechanism includes a drive motor 203 fixedly installed on the rear surface of the slide table 202.

Symmetrical sliders 205 are fixedly installed on the lower surface of the slide table 202, and a telescopic motor 201 is fixedly installed on the upper end of the boss 2. The output end of the telescopic motor 201 passes through the lower end of the slide table 202.

[0026] The clamping mechanism also includes clamping supports 405 symmetrically fixedly installed on the upper surface of the base 408. Each clamping support 405 has a clamping motor 4 fixedly installed on its rear surface, and a rotating arm 401 is rotatably installed on one side of the clamping motor 4.

[0027] A pressure arm 402 is fixedly installed on the upper end of the rotating arm 401. An adjustable telescopic rod 403 is fixedly installed on one side of the upper surface of the pressure arm 402. A pressure block 404 is fixedly installed on the output end of the adjustable telescopic rod 403.

[0028] Symmetrical support seats 407 are fixedly installed on the upper surface of the base 408, and a support pad 406 is fixedly installed on the upper end of each support seat 407.

[0029] Working Principle: Before steel plate cutting, all components of the device must be inspected to ensure that the base 1, tooling base plate 7, adjusting table 3, positioning support 6, drive housing 8, boss 2, base 408, and other basic components are securely installed without any looseness. Simultaneously, check whether the power supply to the rotation motor 801, control motor 305, telescopic motor 201, drive motor 203, and clamping motor 4 is normal; whether the pneumatic or hydraulic systems of the adjusting cylinder 303, propulsion cylinder 602, and telescopic rod adjusting telescopic rod 403 have sufficient pressure and are leak-free; and whether the cutting blade 204 is sharp and undamaged, thus preparing for subsequent cutting operations.

[0030] First, the operator moves the annular steel plate 5 to be cut to the clamping mechanism on the upper end of the tooling base plate 7, placing the annular steel plate 5 on the support pad 406 on the upper end of the support seat 407, which is symmetrically fixed on the upper surface of the base 408. The support pad 406 is made of a material with a certain degree of elasticity. Its function is to prevent the steel plate from directly and rigidly contacting the support seat 407 when supporting the annular steel plate 5, preventing the surface of the steel plate from being scratched. At the same time, it can also provide a certain cushioning effect for the steel plate, ensuring the stability of the steel plate in subsequent processing. At this time, the support seat 407 and the support pad 406 jointly bear the weight of the annular steel plate 5, providing basic support for subsequent clamping, positioning and other operations.

[0031] The plate clamping and adjusting mechanism starts working. After receiving the control signal, the adjusting cylinder 303, which is fixedly installed on the upper fixed seat 301 of the adjusting platform 3, extends its output end, pushing the horizontal connecting plate 308, which is fixedly connected to the output end, to move closer to the annular steel plate 5. During the movement of the horizontal connecting plate 308, the guide shaft 302, which is fixedly installed on its rear surface, passes through the fixed seat 301 and moves synchronously with it. The setting of the guide shaft 302 can effectively ensure the straightness of the horizontal connecting plate 308 during movement, avoid the horizontal connecting plate 308 from shifting during movement, and ensure that the clamping plate 304 can be accurately aligned with the annular steel plate 5.

[0032] When the cross plate 308 moves the clamping plate 304, which is fixedly mounted on the upper part of the front surface, to a suitable clamping position with the annular steel plate 5, the adjusting cylinder 303 stops operating. Subsequently, the three control motors 305, which are fixedly mounted on the outer surface of the clamping plate 304 and correspond to the slide grooves 307, start. The control motors 305 drive the lead screw to rotate through a transmission mechanism such as a lead screw and nut mechanism. The nut on the lead screw is connected to the clamping plate 306, which drives the clamping plate 306, which is slidably mounted in each slide groove 307, to move along the slide groove 307 towards the center of the annular steel plate 5. Since the three clamping plates 306 are arranged at equal angles, they can evenly apply clamping force to the inner wall of the annular steel plate 5 during the movement, initially clamping and fixing the annular steel plate 5 and preventing it from moving radially during subsequent positioning and cutting processes.

[0033] While the plate clamping and adjusting mechanism initially clamps the annular steel plate 5, the clamping mechanism also begins to operate. The clamping motor 4 on the rear surface of the clamping support 405, which is symmetrically fixed on the upper surface of the base 408, starts. The clamping motor 4 drives the rotating arm 401, which is rotated on one side, to rotate upward around the rotation axis through a transmission mechanism such as gear transmission or belt transmission. The pressure arm 402, which is fixedly installed at the upper end of the rotating arm 401, rotates upward synchronously with the rotating arm 401. When the pressure arm 402 rotates to a suitable position above the annular steel plate 5, the clamping motor 4 stops rotating.

[0034] Next, the adjustable telescopic rod 403, fixedly installed on one side of the upper surface of the pressure arm 402, receives a control signal, and its output end extends downward, pushing the pressure block 404, which is fixedly connected to the output end, to move closer to the upper surface of the annular steel plate 5. When the pressure block 404 is in close contact with the upper surface of the annular steel plate 5 and a certain clamping force is applied, the adjustable telescopic rod 403 stops extending. At this time, the pressure block 404 cooperates with the support pad 406 to clamp and fix the annular steel plate 5 from both the top and bottom directions, further enhancing the stability of the annular steel plate 5 during processing and preventing it from vibrating or shifting.

[0035] The plate limiting mechanism begins to operate. Upon receiving a control signal, the propulsion cylinder 602, fixedly mounted on the upper cylinder seat 601 of the positioning support 6, extends its output end through the cylinder seat 601 and towards the annular steel plate 5, pushing the limiting plate 604, which is fixedly connected to its output end, to move synchronously. During the movement of the limiting plate 604, the symmetrical limiting shaft 603 fixedly mounted on its rear surface also moves accordingly. The setting of the limiting shaft 603 ensures the stability and straightness of the limiting plate 604 during movement, preventing the limiting plate 604 from tilting or shifting during the movement.

[0036] When the limiting plate 604 moves to contact the outer wall of the annular steel plate 5, the propulsion cylinder 602 stops extending. By contacting the outer wall of the annular steel plate 5, the limiting plate 604 precisely limits the position of the annular steel plate 5, ensuring that the annular steel plate 5 is in the preset processing position during subsequent rotation and cutting, thus guaranteeing the accuracy of the cutting dimensions.

[0037] The plate rotation mechanism starts working, and the rotary motor 801, which is fixedly installed on the outside of the drive housing 8, starts. The output end of the rotary motor 801 drives the drive gear 802, which is fixedly connected to it, to rotate. Since the follower gear 804, which is fixedly installed on one side of the drive cam 803, which is rotatably installed on both sides of the drive gear 802 inside the drive housing 8, meshes with the drive gear 802, the rotation of the drive gear 802 will drive the two follower gears 804 to rotate synchronously, thereby driving the drive cam 803 to rotate.

[0038] During the rotation of the drive cam 803, its contour surface contacts the edge of the annular steel plate 5, and the frictional force drives the annular steel plate 5 to rotate slowly around its center. During the rotation of the annular steel plate 5, the clamping plate 306 of the plate clamping and adjusting mechanism maintains a certain clamping force on the annular steel plate 5, ensuring that the annular steel plate 5 rotates synchronously with the drive cam 803, and that the rotation is smooth without slippage. Simultaneously, the pressure block 404 of the clamping mechanism also maintains a constant pressure on the annular steel plate 5, preventing it from jumping up and down during rotation.

[0039] As the plate rotation mechanism drives the annular steel plate 5 to rotate, the plate cutting mechanism also adjusts its position before cutting. The telescopic motor 201, fixedly mounted on the upper end of the boss 2, starts. The output end of the telescopic motor 201 passes through the lower end of the slide table 202 and drives the slide table 202 to slide along the guide rail on the upper end of the boss 2. The symmetrical slider 205 fixedly mounted on the lower surface of the slide table 202 cooperates with the guide rail on the boss 2 to ensure the smoothness and straightness of the slide table 202's sliding. By rotating the telescopic motor 201 forward and backward, the position of the slide table 202 on the boss 2 can be adjusted, thereby adjusting the distance between the plate cutting mechanism fixedly mounted on the upper end of the slide table 202 and the annular steel plate 5, so that the cutting blade 204 is aligned with the position on the annular steel plate 5 to be cut.

[0040] When the plate cutting mechanism is adjusted to the appropriate cutting position, and the annular steel plate 5 rotates at a stable speed under the drive of the plate rotation mechanism, the drive motor 203 in the plate cutting mechanism starts. The output end of the drive motor 203 passes through the slide table 202 and drives the cutting blade 204, which is rotatably mounted thereto, to rotate at high speed. The high-speed rotating cutting blade 204 contacts the part of the annular steel plate 5 to be cut, and the cutting operation on the annular steel plate 5 begins.

[0041] During the cutting process, the annular steel plate 5 continuously rotates around its center, ensuring that the cutting blade 204 can continuously cut along the circumference of the annular steel plate 5. Simultaneously, the operator can fine-tune the position of the slide table 202 by controlling the telescopic motor 201, ensuring that the cutting depth and trajectory meet the requirements for large milk tank production. The plate clamping and adjusting mechanism, clamping mechanism, and plate limiting mechanism remain operational at all times, ensuring the stability and positional accuracy of the annular steel plate 5 during the cutting process.

[0042] After the cutting operation of the annular steel plate 5 is completed, the drive motor 203 is first turned off, causing the cutting blade 204 to stop rotating. Next, the telescopic motor 201 drives the slide table 202 and the plate cutting mechanism to reset and move away from the annular steel plate 5. Then, the rotation motor 801 of the plate rotation mechanism stops working, and the annular steel plate 5 stops rotating.

[0043] Subsequently, the output end of the adjustable telescopic rod 403 of the clamping mechanism retracts, causing the pressure block 404 to move upward and disengage from the upper surface of the annular steel plate 5; the clamping motor 4 drives the rotating arm 401 and the pressure arm 402 to rotate downward and reset. The control motor 305 of the plate clamping and adjusting mechanism drives the clamping plate 306 to move along the slide groove 307 away from the center of the annular steel plate 5, releasing the annular steel plate 5; the output end of the adjusting cylinder 303 retracts, causing the horizontal connecting plate 308 and the clamping plate 304 to reset. The output end of the pushing cylinder 602 of the plate limiting mechanism retracts, causing the limiting plate 604 to reset and disengage from the outer wall of the annular steel plate 5.

[0044] Finally, the operator removes the cut annular steel plate 5 from the support pad 406, completing the entire steel plate cutting process for large milk tank production. Simultaneously, all components of the equipment are cleaned and inspected to prepare for the next cutting operation.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
