[0046] Embodiment 2:

[0047] As Figure 1 、 Figure 2 shown, on the basis of the above Embodiment 1, a trimming knife feeding assembly is arranged on one side of the trimming platform 1. The trimming knife feeding assembly includes: a gantry 11, a lifting cylinder 12, and a lifting plate 13.

The sliding grooves and the sliding rails slide relative to each other to guide the lifting plate 13. The lifting plate 13 drives the trimming knife 2 below to move downward, and the trimming knife 2 shears the stainless steel water tank plate below. The width of the trimming knife 2 is greater than that of the stainless steel water tank plate, enabling synchronous trimming of various positions on the edge of the stainless steel water tank plate, making the trimmed edge neater and reducing burrs.

[0050] Embodiment 3:

[0051] As Figure 1 、 Figure 2 shown, on the basis of the above Embodiment 2, a shearing tip is provided at the bottom of the trimming knife 2, and a cutting groove 14 is provided at the top of the trimming platform 1. The cutting groove 14 is located directly below the shearing tip.

[0052] The working principle and beneficial effects of the above technical solution are:

[0053] The shearing tip provided at the bottom of the trimming knife 2 can concentrate the pressure and improve the shearing effect on the stainless steel water tank plate; a cutting groove 14 is provided below the shearing tip to avoid the trimming knife 2 after shearing is completed.

[0054] Embodiment 4:

[0055] As Figure 1 、 Figure 3 shown, on the basis of the above Embodiment 1, the sheet positioning assembly 4 includes: a positioning frame 21 and positioning sliding sleeves 22. The four corner points of the bottom surface of the positioning frame 21 are connected to the trimming platform 1 through support rods. The positioning frame 21 includes two cross beams, and the length direction of the cross beams is consistent with the sheet conveying direction; the positioning sliding sleeves 22 are slidably connected to the cross beams of the positioning frame 21, and an upper positioning clamping assembly and a side positioning clamping assembly are connected to the positioning sliding sleeves 22; a plurality of positioning sliding sleeves 22 are provided on each cross beam, and the positions of the positioning sliding sleeves 22 on the two cross beams on both sides correspond.

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] In the sheet positioning assembly 4, a rectangular positioning frame 21 is provided as a support framework. The positioning frame 21 is arranged above the conveyor belt assembly 3. A plurality of positioning sliding sleeves 22 are provided on the two cross beams on the left and right of the positioning frame 21. According to the different lengths of the stainless steel water tank sheet to be trimmed, the positioning sliding sleeves 22 are pushed to slide on the positioning frame 21, so that a plurality of positioning sliding sleeves 22 are evenly arranged above the stainless steel water tank sheet; both an upper positioning clamping assembly and a side positioning clamping assembly are provided on the positioning sliding sleeves, thereby realizing the synchronous movement of the clamping assemblies, adapting to adjust the positioning points of the stainless steel water tank sheet, and improving the fixing effect on the stainless steel water tank sheet.

[0058] Example 5:

[0059] As Figure 3 , Figure 4 shown, on the basis of the above Example 4, the upper positioning and clamping assembly includes:

[0060] The first lug 31, and the first lug 31 is connected to the inner side of the positioning sliding sleeve 22;

[0061] The first swing rod 32, the middle part of the first swing rod 32 is hinged to the first lug 31, the bottom of the first swing rod 32 inclines towards the inside of the positioning frame 21, the top of the first swing rod 32 bends outwards from the positioning frame 21, a first waist-shaped slot 33 is arranged on the bent section of the first swing rod 32, and a sliding shaft 34 is slidably connected in the first waist-shaped slot 33;

[0062] The electric telescopic rod 35, the electric telescopic rod 35 is connected to the top end of the positioning sliding sleeve 22, and the telescopic end of the electric telescopic rod 35 is connected to the sliding shaft 34;

[0063] The upper positioning plate 36, two positioning sliders 37 are slidably connected to the top end of the upper positioning plate 36, and the two positioning sliders 37 are respectively hinged to the bottom ends of the first swing rods 32 on both sides.

[0064] The working principle and beneficial effects of the above technical solution are as follows:

[0065] When the upper positioning and clamping assembly is used, start the electric telescopic rod 35 to make its top end extend upwards. The electric telescopic rod 35 drives the sliding shaft 34 to move upwards. The sliding shaft 34 slides in the first waist-shaped slot 33, moving from the bottom end of the first waist-shaped slot 33 to the top end of the first waist-shaped slot 33, making the bent section of the first swing rod 32 rotate inwards, the bottom end of the first swing rod 32 rotate in the direction away from the center of the positioning frame 21, the first swing rod 32 gradually approaches the vertical state, the bottom end of the first swing rod 32 pulls the positioning slider 37 to slide on the upper positioning plate 36, making the upper positioning plate 36 move downwards and press against the upper part of the stainless steel water tank plate; the electric telescopic rods 35 on both sides act synchronously, making the moving distances on both sides of the upper positioning plate 36 equal, making the positioning points of the stainless steel water tank plate centered, and the forces on both sides of the stainless steel water tank plate are evenly distributed.

[0066] The upper positioning plate 36 is set as an arc-shaped plate that bends upwards, and a chute is arranged on the top surface of the arc-shaped plate. The positioning slider 37 is slidably connected in the chute. This structure can increase the moving amount of the upper positioning plate 36 in the vertical direction when the first swing rod 32 drives the positioning slider 37 to rotate, and improve the range of plate thickness that the upper positioning plate 36 can adapt to.

[0067] Through the above structural design, the rapid movement of the upper positioning plate 36 is achieved by the action of the electric telescopic rod 35, so that it moves downward to position and press the center of the top of the stainless steel water tank plate, reducing the warping of the plate center during the positioning process and reducing the shaking of the plate center during the edge cutting process, thereby improving the edge cutting quality.

[0068] Embodiment 6:

[0069] As Figure 3 、 Figure 4 shown, on the basis of the above Embodiment 5, the side positioning and clamping assembly includes:

[0070] The second lug 41 is connected to the outside of the positioning sliding sleeve 22;

[0071] The second swing rod 42 has its middle part hinged to the second lug 41. The bottom of the second swing rod 42 inclines outward from the positioning frame 21, the top of the second swing rod 42 bends inward toward the positioning frame 21, and the second swing rod 42 is arranged staggeredly with the first swing rod 32; a second waist-shaped slot 43 is provided in the bent section of the second swing rod 42, and the sliding shaft 34 is slidably connected in the second waist-shaped slot 43;

[0072] The side positioning plate 44 is rotatably connected to the bottom end of the second swing rod 42, and the inner side of the side positioning plate 44 is set as a clamping surface.

[0073] The working principle and beneficial effects of the above technical solution are as follows:

[0074] When the lower positioning and clamping assembly is in use, start the electric telescopic rod 35 to make its top end extend upward. The electric telescopic rod 35 drives the sliding shaft 34 to move upward. The sliding shaft 34 slides in the second waist-shaped slot 43, moving from the bottom end of the second waist-shaped slot 43 to the top end of the second waist-shaped slot 43, so that the bent section of the second swing rod 42 rotates outward, the bottom end of the second swing rod 42 rotates toward the center of the positioning frame 21, the second swing rod 42 gradually approaches the vertical state, and the side positioning plate 44 at the bottom end of the second swing rod 42 approaches the stainless steel water tank plate, clamping both sides of the stainless steel water tank plate. When the side positioning plate 44 contacts the stainless steel water tank plate, it can rotate to make full contact with the side of the plate.

[0075] When edge cutting the stainless steel water tank plate, first start the electric telescopic rod 35 to make both the upper positioning plate 36 and the side positioning plate 44 approach the plate. The stainless steel water tank plate moves toward the center under the action of the side positioning plate 44 and is regularized to a preset angle. At this time, there is a small gap or small pressure between the upper positioning plate 36 and the side positioning plate 44 and the stainless steel water tank plate, which does not affect the movement of the stainless steel water tank plate. When the stainless steel water tank plate moves to the edge cutting position, start the electric telescopic rod 35 again to make the upper positioning plate 36 and the side positioning plate 44 contact the plate and maintain sufficient pressure.

[0076] Through the above structural design, by controlling the movement of the electric telescopic rod 35, the synchronous movement of the upper positioning plate 36 and the side positioning plate 44 can be effectively achieved, regular positioning is carried out on the plate during the movement of the plate, and it is automatically adjusted to the preset trimming angle; after moving in place, the plate is automatically fixed, realizing the fixation of the plate during the trimming process and preventing the displacement of the stainless steel water tank plate during trimming.

[0077] Embodiment 7:

[0078] As Figure 3 、 Figure 4 As shown in the figure, on the basis of the above Embodiment 6, a support sleeve 45 is connected to the second swing rod 42, a through hole is provided on the support sleeve 45, a linkage rod is connected to a plurality of second swing rods 42 on the same side, and the linkage rod simultaneously passes through the through holes of a plurality of support sleeves 45.

[0079] The working principle and beneficial effects of the above technical solution are:

[0080] By providing the support sleeve 45 on the second swing rod 42 and connecting the support sleeves 45 of a plurality of second swing rods 42 through the linkage rod, the synchronous movement of a plurality of second swing rods 42 on the same side can be realized, so that the positions of the side positioning plates 44 on the same side are the same, and the deflection caused by different side positioning points during the positioning of the stainless steel water tank plate is prevented.

[0081] Embodiment 8:

[0082] As Figures 3 - 5 As shown in the figure, on the basis of the above Embodiment 4, a clamping seat 23 is provided at the bottom of the positioning sliding sleeve 22, a sensor receiving groove 24 is provided at the bottom of the clamping seat 23, a clamping plate 25 is slidably connected in the sensor receiving groove 24, one end of the clamping plate 25 is threadedly connected to an adjusting bolt 26, and the adjusting bolt 26 is rotatably connected to the side wall of the clamping seat 23; a laser displacement sensor is installed in the sensor receiving groove 24 and is clamped by the clamping plate 25.

[0083] The working principle and beneficial effects of the above technical solution are:

[0084] The clamping seat 23 at the bottom of the positioning sliding sleeve 22 is used to install the laser displacement sensor. The housing of the laser displacement sensor is inserted into the sensor receiving groove 24 of the clamping seat 23, and the adjusting bolt 26 is rotated to make it threadedly drive with the clamping plate 25. The clamping plate 25 can only move horizontally in the clamping seat 23, so that the clamping plate 25 approaches the housing of the laser displacement sensor and clamps it.

[0085] The laser displacement sensor is electrically connected to the controller. The laser displacement sensor is connected to the positioning sliding sleeve 22, and the position of the sheet below the positioning sliding sleeve 22 is set as the detection point. The laser displacement sensor can obtain the displacement change of the detection point before and after trimming. The controller receives the displacement detection data and evaluates the displacement of the stainless steel water tank sheet before and after trimming. When any displacement exceeds the preset range, it indicates that the stainless steel water tank sheet has large deformation or warping after trimming, and the corresponding trimming accuracy cannot be guaranteed. At this time, it is necessary to re-detect and repair the sheet accuracy. When the displacement exceeds the preset range for many times, it is necessary to overhaul the equipment.

[0086] Embodiment 9:

[0087] As Figure 6 shown, on the basis of the above Embodiment 5, the upper positioning plate 36 is provided with a frame structure with an open bottom, and a pressing roller assembly is arranged on the upper positioning plate 36. The pressing roller assembly includes:

[0088] A limiting frame 51, the limiting frame 51 is attached to the top of the inner wall of the upper positioning plate 36, and a plurality of limiting protrusions 52 with the same height are arranged at the bottom of the limiting frame 51;

[0089] An elastic frame, the elastic frame is connected to the center of the limiting frame 51. The elastic frame includes an elastic arm 53 in the center and pressing roller frames 54 on both sides. The two elastic arms 53 can extend to both sides;

[0090] A pressing roller 55, the pressing roller 55 is rotatably connected to the pressing roller frame 54, and the bottom end of the pressing roller 55 is lower than the upper positioning plate 36.

[0091] The working principle and beneficial effects of the above technical solution are as follows:

[0092] The upper positioning plate 36 in the upper positioning and clamping assembly can be set as the above elastic structure. When the upper positioning plate 36 contacts the stainless steel water tank sheet, the pressing roller 55 of the upper positioning plate 36 first contacts the top surface of the sheet; there is friction between the pressing roller 55 and the sheet and it can roll relatively, which will not affect the movement of the sheet. When the sheet moves to the trimming position, the upper positioning plate 36 continues to move downward, and applies pressure to the sheet through the pressing roller 55. The pressing roller 55 is squeezed to drive the elastic arm 53 to deform. Since the elastic arm 53 is set as a Z-shaped structure, the two elastic arms 53 can expand outward, so that while the two pressing rollers 55 are squeezed upward, they move to both sides, pushing the sheet flat to both sides; when the pressing roller frame 54 moves upward to contact the limiting protrusion 52 and then stops moving, so that the pressing roller 55 maintains a stable pressure on the stainless steel water tank sheet. When the pressure exceeds the preset value, the friction between the pressing roller 55 and the sheet is large enough, and the stainless steel water tank sheet does not move during the trimming process.

[0093] With the above structural design, the upper positioning plate 36 is elastically arranged. The pressure roller 55 contacts the stainless steel water tank plate. By adjusting the pressure of the pressure roller 55 on the stainless steel water tank plate, the state during the movement and press-fitting positioning of the stainless steel water tank plate can be adapted. During press-fitting positioning, the pressure roller 55 moves towards both sides simultaneously, pushing the plate flat towards both sides, avoiding the problem of the middle part of the plate bulging and warping under the clamping action of the side positioning plate 44, and effectively ensuring the position accuracy of the plate.

[0094] Embodiment 10:

[0095] As Figure 6 shown, on the basis of the above Embodiment 9, a pipeline 56 is arranged at the center of the upper positioning plate 36. The air inlet of the pipeline 56 is connected to an air pump. The pipeline 56 passes through the center of the limit frame 51 and the elastic frame. The air outlet of the pipeline 56 is communicated with the cavity of the pressure roller 55 through a flexible pipeline 57. A plurality of air flow holes 58 are evenly distributed on the surface of the pressure roller 55.

[0096] The working principle and beneficial effects of the above technical solution are as follows:

[0097] When the upper positioning plate 36 is in use, air is pumped into the pipeline 56 by an air pump, then enters the pressure roller 55 through the flexible pipeline 57 at the air outlet, and flows out through the air flow holes 58. The air blows towards the upper surface of the stainless steel water tank plate, cleaning the dust on the plate surface to prevent scratches on the plate surface by foreign objects on the surface during the movement of the pressure roller 55.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
