[0002] The main packaging container for ketchup is a conical iron barrel with a capacity of 215 liters or 225 liters. The conical iron barrel is a paint barrel with a conical opening, an opening diameter of 552.5 mm, a height of 1000 mm or 1025 mm, and an inner diameter of the barrel bottom of 516 mm. When making a conical iron barrel, the thin plate needs to be cut and then transferred to the next process. During the cutting process of the thin plate, the thin plate needs to be cut into sections according to actual needs. A conveyor belt is set downstream of the cutting device. The thin plate to be cut passes through the conveyor belt. When the cutting device is in operation, the thin plate is placed on a conveyor belt and then transported to the downstream production process. However, in the actual production process, since the length of the thin plate is greater than the width, the thin plate is prone to offset during the stacking process, which is inconvenient for the transportation and transfer of multiple stacked thin plates. At the same time, during the stacking process, the thin plate is conveyed in the direction, and the lower side of the thin plate in the front will rub against the entire surface of the thin plate, causing the surface of the thin plate to be scratched, reducing the quality of the thin plate, and making it inconvenient for the production of conical iron barrels and the filling of ketchup. Summary of the Invention

[0014] The setting of the blanking assembly can place the cut thin plates neatly on the upper side of the second conveyor, so that the thin plates can be neatly stacked together when transported to the blanking rack by the second conveyor, which is convenient for subsequent transfer and transportation of the thin plates.

[0015] When a protective baffle is fixedly installed on the inner left side of the support frame, and the lower part of the protective baffle is tilted to the right relative to the upper part, the front side of the thin plate is transported from back to front by the second conveyor, and the right side of the thin plate contacts with the inner wall of the blanking rack or the upper side of the right part of the thin plate below, and the left part of the thin plate contacts with the right side of the lower part of the protective baffle. In this way, the protective baffle can support the left part of the thin plate, so that the left part of the thin plate maintains a distance from the inner wall of the blanking rack or the upper side of the left part of the thin plate below. In this way, the thin plate can be prevented from rubbing and sliding on the inner wall of the blanking rack or the upper side of the thin plate below, and damage to the upper and lower surfaces of the thin plate caused by friction of the thin plate can be avoided. In this way, the quality of the thin plate after cutting can be guaranteed, which is convenient for subsequent further processing of the thin plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0021] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 The positional relationships of front, back, top, bottom, left, and right are described in the layout of the manual. Figure 1 The layout direction is determined by the

[0022] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0023] Example 1: As shown in the attached Figure 1 、 2 As shown in Figure 3, the material splicing device for thin plate processing includes a shearing machine 1 for cutting thin plates, and also includes a blanking assembly and a splicing assembly. A first conveyor 2 with a conveying direction from right to left is provided on the left side of the shearing machine 1, and a second conveyor 3 with a conveying direction from back to front is provided on the left side of the first conveyor 2. A blanking assembly capable of placing the thin plate conveyed to the left by the first conveyor 2 on the upper side of the second conveyor 3 is provided on the upper side of the second conveyor 3. The splicing assembly includes a support frame 5 and a protective baffle 4. A support frame 5 is fixedly installed in front of the second conveyor 3, and a protective baffle 4 is fixedly installed on the inner side of the left part of the support frame 5. The lower part of the protective baffle 4 is inclined to the right relative to the upper part (attached). Figure 1 ).

[0024] Alternatively, a protective baffle 4 is fixedly mounted on the inner side of the right side of the support frame 5, and the lower part of the protective baffle 4 is tilted to the left relative to the upper part (see FIG. Figure 2 ).

[0025] According to the requirements, the shearing machine 1 is an existing well-known technology. A decoiler is provided on the right side of the shearing machine 1. The model of the decoiler is KJ-1600*12T. The decoiler is used to install rolled thin plates (color-coated coils) and continuously feed to the right side of the shearing machine 1. The conveying height of the first conveyor 2 is greater than the conveying height of the second conveyor 3. During use, after the shearing machine 1 has cut the thin plate according to the design specifications, it is transported to the upper left side of the first conveyor 2. The length of the thin plate in this application is greater than the width. The direction in which the first conveyor 2 transports the cut thin plate is consistent with the length direction of the thin plate, and the width direction of the thin plate is consistent with the conveying direction of the second conveyor 3. In this way, the first conveyor 2 and the second conveyor 3 can convert the conveying direction of the thin plate from along the length direction to along the width direction. In this way, the thin plates are finally stacked in the blanking rack 7, and the forklift can insert multiple stacked thin plates along the width direction of the thin plates. The forklift inserting the thin plates in front of the second conveyor 3 is less difficult than inserting the thin plates on the left and right sides of the second conveyor 3. It can avoid collision between the forklift and the equipment and improve safety. At the same time, the forklift forks the thin plates along the width direction of the thin plates, and the fork arm of the forklift is located in the middle position in the length direction of the thin plates, which can improve stability after inserting the thin plates and avoid overturning and falling off during transfer and transportation.

[0026] The setting of the blanking assembly can place the cut thin plates neatly on the upper side of the second conveyor 3, so that the thin plates can be transported by the second conveyor 3 to the blanking rack 7 and can be neatly stacked together, which is convenient for subsequent transfer and transportation of the thin plates.

[0027] When the left side of the sheet metal is separated from the second conveyor 3, the left side of the sheet metal is separated from the protective baffle 4 and falls down, or it can slide sideways under the action of the inclined surface of the protective baffle 4 and fall down after separation from the protective baffle 4, which is convenient for subsequent further processing of the sheet metal.

[0028] The above-mentioned material receiving device for thin plate processing can be further optimized and / or improved according to actual needs:

[0029] Example 2: As an optimization of the above example, as shown in the attached Figure 1、 2 As shown, two insertion slots 6 with upward openings and through-through front and back are provided at intervals on the left and right sides of the inner upper side of the support frame 5 .

[0030] According to the requirements, two profiles are fixedly installed on the inner side of the lower part of the support frame 5 at intervals. The profiles can be H-shaped steels that are well known in the art. The left and right sides of the two profiles are insertion slots 6. During use, with this arrangement, when a certain number of thin plates fall from the upper side of the two profiles, the thin plates are transported to the next process using a forklift. The provision of the insertion slots 6 facilitates the transportation and transfer of thin plates in batches.

[0031] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 3, the blanking assembly includes a blanking rack 7, a slide bar 8, a front blanking baffle 9, a rear blanking baffle 10, a front drive mechanism and a rear drive mechanism 23. The blanking rack 7 is fixedly installed on the upper rear side of the second conveyor 3 corresponding to the position of the first conveyor 2. A plurality of front and rear slide bars 8 are fixedly installed on the upper left and right sides of the blanking rack 7. The outer side of each slide bar 8 is spaced from front to back with a front sliding sleeve 11 and a rear sliding sleeve 12. The front blanking baffle 9 and the rear blanking baffle are spaced front and back inside the blanking rack 7. 10. The lower part of the front blanking baffle 9 is tilted backward relative to the upper part, and the upper side of the front blanking baffle 9 is fixedly installed together with the lower side of each front slide 11. The lower part of the rear blanking baffle 9 is tilted forward relative to the upper part, and the upper side of the rear blanking baffle 9 is fixedly installed together with the lower side of each rear slide 12. A front driving mechanism capable of moving the front blanking baffle 9 forward and backward is provided on the upper front side of the blanking rack 7, and a rear driving mechanism 23 capable of moving the rear blanking baffle 10 forward and backward is provided on the upper rear side of the blanking rack 7.

[0032] According to needs, a plate-shaped baffle is fixedly installed on the inner left side of the blanking rack 7, which can prevent the first conveyor 2 from causing the thin plate to move too fast and slide out of the blanking rack 7. It can also limit the thin plate so that the position of the thin plate remains consistent each time it falls, which is convenient for the subsequent stacking of thin plates. During use, through such an arrangement, the first conveyor 2 conveys the thin plate cut by the shearing machine 1 from right to left to between the front blanking baffle 9 and the upper part of the rear blanking baffle 10. The lower part of the front blanking baffle 9 is tilted backward relative to the upper part, and the lower part of the rear blanking baffle 10 is tilted forward relative to the upper part. In this way, the thin plate moves between the front blanking baffle 9 and the upper part of the rear blanking baffle 10, which can support the thin plate. Then the front drive mechanism and the rear drive mechanism 23 are actuated to separate the front blanking baffle 9 and the rear blanking baffle 10 from each other, so that the thin plate can fall to the upper side of the second conveyor 3, so that the conveying direction of the thin plate is consistent, and finally the thin plates can be neatly stacked together on the blanking rack 7, which is convenient for transportation and transfer of the thin plates.

[0033] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown in FIG3 , the lower end of the front blanking baffle 9 is bent downward to form a front connecting section 13 , and the lower end of the rear blanking baffle 10 is bent downward to form a rear connecting section 14 .

[0034] During use, such an arrangement can improve the strength of the front blanking baffle 9 and the rear blanking baffle 10 .

[0035] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 3, the blanking assembly also includes a front adjusting mechanism and a rear adjusting mechanism 19. The front adjusting mechanism includes a front fixing frame 15, a front pull rod 16 and a front guide rod 17. A front fixing frame 15 is provided on the inner side of the front of the blanking frame 7. The upper side of the front fixing frame 15 is fixedly installed with the lower side of each front sliding sleeve 11. The front side of the front blanking baffle 9 is fixedly installed in the front fixing frame 15. The lower side of the front connecting section 13 is fixedly installed with the inner side of the lower part of the front fixing frame 15. A number of vertical front pull rods 16 are fixedly installed at intervals on the left and right sides of the blanking frame 7 corresponding to the front position of the front fixing frame 15. The lower end of each front pull rod 16 is provided with a front guide hole 18 that passes through the front and back. A front guide rod 17 is installed in each front guide hole 18. The front end of each front guide rod 17 is fixedly installed with the corresponding position on the rear side of the front connecting section 13. The rear adjusting mechanism 19 has the same structure as the front adjusting mechanism and is symmetrically distributed.

[0036] As needed, each front tie rod 16 is provided with a left-right through-hole adjustment screw on the right side of its lower end. Each adjustment screw hole is threaded with an adjustment screw. By turning the adjustment screw, the front guide rod 17 can be prevented from swinging left and right when moving forward and backward, thereby improving stability. During use, the front fixing frame 15 and the rear adjustment mechanism 19 can increase the strength of the front and rear blanking baffles 9, 10, preventing them from deforming. This prevents the cut sheets from tilting and falling outside the second conveyor 3 after being cut, thereby improving the stability of sheet conveying.

[0037] Example 6: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 3, the front driving mechanism includes a fixed plate 20, a mounting seat 21 and a driving cylinder 22. The fixed plate 20 is fixedly installed on the front side of the middle part of the blanking rack 7, and the mounting seat 21 is fixedly installed on the upper side of the front fixed frame 15 corresponding to the position of the fixed plate 20. The driving cylinder 22 is fixedly installed on the rear side of the fixed plate 20, and the rear end of the piston rod of the driving cylinder 22 is installed together with the mounting seat 21. The rear driving mechanism 23 has the same structure as the front driving mechanism and is symmetrically distributed.

[0038] According to the requirements, the driving cylinder 22 is a known technology. During use, through such a setting, the driving cylinder 22 and the rear driving mechanism 23 can move synchronously. After the piston rod of the driving cylinder 22 is extended, the front blanking baffle 9 and the rear blanking baffle 10 approach each other, so that the first conveyor 2 transports the cut thin plates from right to left to between the front blanking baffle 9 and the rear blanking baffle 10. Then, after the piston rod of the driving cylinder 22 is retracted, the front blanking baffle 9 and the rear blanking baffle 10 separate from each other, so that the thin plates fall on the upper side of the second conveyor 3, and the second conveyor 3 then transports the thin plates from back to front. The rear driving mechanism 23 has the same structure as the front driving mechanism and is symmetrically distributed, which can realize the synchronous movement of the front blanking baffle 9 and the rear blanking baffle 10, and can also make the front blanking baffle 9 and the rear blanking baffle 10 quickly approach or quickly separate, so that the thin plates are quickly transported from the left side of the first conveyor 2 to the upper side of the second conveyor 3.

[0039] Example 7: As an optimization of the above embodiment, as shown in the attached Figure 3 As shown, an adjusting screw 24 is fixedly installed at the center of the front end of the piston rod of the driving cylinder 22, and a mounting hole that passes through the front and back is provided on the front side of the mounting seat 21. The rear end of the adjusting screw 24 passes through the mounting hole and is screwed with a rear adjusting nut 26. The front outer side of the adjusting screw 24 corresponding to the front side position of the mounting seat 21 is screwed with a front adjusting nut 25.

[0040] According to the requirements, there are two slide bars 8, which are respectively arranged on the left and right sides of the driving cylinder 22. During use, by setting the front adjusting nut 25 and the rear adjusting nut 26, the adjusting screw 24 can be conveniently fixed to the mounting base 21, so that the piston rod of the driving cylinder 22 can drive the mounting base 21 and the front fixing frame 15 to move forward and backward stably during extension and contraction. At the same time, by adjusting the positions of the front adjusting nut 25 and the rear adjusting nut 26, the initial position of the front fixing frame 15 can be adjusted. The distance between the front blanking baffle 9 and the rear blanking baffle 10 can be adjusted according to the thin plates of different widths, so that the thin plates moved between the front blanking baffle 9 and the rear blanking baffle 10 can be placed on the upper side of the second conveyor 3 at the same time.

[0041] Example 8: As an optimization of the above embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 3, the first conveyor 2 and the second conveyor 3 are both roller conveyors. A left pressing seat 27 and a right pressing seat 28 are provided on the left and right sides of the upper front side of the second conveyor 3. The upper sides of the left pressing seat 27 and the right pressing seat 28 are provided with a U-shaped rotating groove 29 that passes through the left and right sides and opens upward. A pressing shaft 30 is rotatably installed in the rotating groove 29, and a pressing roller 31 is fixedly installed on the outer side of the pressing shaft 30. There is a distance between the outer side of the lower part of the pressing roller 31 and the upper side of the roller of the second conveyor 3.

[0042] According to the requirements, the left and right ends of the clamping shaft 30 are fixedly installed with limit baffles, which can prevent the clamping shaft 30 from separating from the left clamping seat 27 or the right clamping seat 28 when moving left and right. During use, through such a setting, when the cut thin plate is transported from back to front by the second conveyor 3, when the front end of the thin plate falls along the protective baffle 4, the clamping roller 31 presses on the upper side of the rear part of the thin plate, which can decelerate the thin plate when it falls on the upper side of the blanking rack 7, avoiding the damage and scratches caused by the entire thin plate due to excessive speed during the falling process, improving the cutting quality of the thin plate, facilitating the subsequent processing of the thin plate, and reducing the falling speed of the thin plate. It can also reduce safety risks and avoid safety accidents caused by the thin plate falling to the outside of the blanking rack 7.

[0043] The above technical features respectively constitute the various embodiments of the present invention, which have strong adaptability and optimal implementation effects. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
