Description

Technical Field

[0001] The invention relates to the technical field of cutting, in particular to a shaping and cutting device for cardboard production. Background Art

[0002] In the paper processing and packaging industry, the cardboard after gluing and drying needs to pass through the cooling zone to stabilize its shape, and the flattening device needs to ensure that the surface of the cardboard is flat to shape it. After that, the cardboard is pushed from the shaping process to the cutting process, ready to receive precise processing of size and shape.

[0003] When the cardboard is cut automatically after being shaped, in order to improve the cutting efficiency, multiple cardboards are usually stacked by belts, and then transported in batches from the shaping area to the cutting area. In the process of transporting the cardboards by the belts, due to the different friction between the belt and the bottom cardboard and between the cardboards, or the sudden change in the speed or acceleration of the belt, or the vibration of the belt by external force, many reasons may cause relative sliding between the cardboards, resulting in serious misalignment between the cardboards when they reach the cutting point, which in turn leads to inconsistent cardboard cutting sizes.

[0004] For this reason, according to the above-mentioned problem, a kind of cardboard production shaping and cutting equipment has been designed. Summary of the invention

[0005] In order to overcome the shortcomings of the background art, the present invention provides a shaping and cutting device for cardboard production.

Two first telescopic rods are fixedly connected on both sides of the guide frame, and an inclined block is fixedly connected between the telescopic ends of adjacent first telescopic rods. The moving rod is fixedly connected to a sliding rod symmetrically distributed along the moving rod, and the sliding rod is limitedly matched with the adjacent guide frame, and the sliding rod is slidably connected to the adjacent moving frame, and the sliding rod contacts the inclined block, and the pressure plate is fixedly connected to a convex rod, and the convex rod is movably connected to the moving rod.

[0007] Optionally, the guide frame is provided with a roundabout groove, and the sliding rod slides along the roundabout groove of an adjacent guide frame.

[0010] Optionally, the push block is made of rubber material.

[0011] Optionally, it further comprises tooth plates symmetrically distributed along the frame, the tooth plates are fixedly connected to the frame, and the top block moves to be pressed and matched with the adjacent tooth plates.

[0012] Optionally, it further includes elastic components symmetrically distributed along the top block, and two ends of the elastic components are respectively fixedly connected to the adjacent top block and the first mounting frame.

[0013] Optionally, it further comprises spring sheets symmetrically distributed along the adjacent top blocks, and two ends of the spring sheets are respectively fixedly connected to the adjacent top blocks and the push blocks.

[0015] Optionally, a second support frame is further included which is symmetrically distributed along the frame, the second support frame is fixedly connected to the frame, and the second support frame is rotatably connected to a plurality of pressure wheels.

[0016] The present invention has the following advantages: compared with belt conveyors, the present invention can smoothly push the stacked cardboards backward to just below the cutting assembly through the limiting rotating frame, and when the limiting rotating frame moves forward and resets, it can avoid the new cardboards on the front side of the placement plate, without affecting the next batch of cardboards to be cut being placed on the front side of the placement plate.

[0017] When the position-limiting rotating frame moves forward and resets, the first telescopic rod at the rear side is reset to drive the inclined block at the rear side to move downward, so that the moving rod presses the pressing plate downward through the convex rod, thereby driving the position-limiting rotating frame to swing upward, avoiding affecting the next batch of cardboards to be cut and placed on the front side of the frame.

[0018] When the cardboard is transported to the rear side of the frame, the push block starts to intermittently push the left and right sides of the cardboard, so that the stacked cardboards are aligned in the left and right directions, thereby preventing the left and right sides of the stacked cardboards from being misaligned when cutting.

[0019] The present invention provides a buffering and protective effect on the top block through the third telescopic rod and the spring sheet, thereby preventing the push block from being unable to push the paperboard, causing the tooth plate to squeeze the top block.

[0020] The present invention uses a limiting plate to limit and guide the cardboard pushed backward on the placement plate, and uses a pressing wheel to press the top of the topmost cardboard to assist the cardboard to be transported backward stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] Embodiment 1: A cutting device for forming paperboard production, such as Figures 1 to 7As shown, it includes a frame 1, a cutting component 11 is installed on the rear side of the frame 1, and the cutting component 11 is installed with a clamping component 12 symmetrically distributed along the front and rear of the cutting component 11, a placing plate 13 is fixedly connected to the front side of the frame 1, and the cutting component 11 is located directly above the frame 1 and the placing plate 13, and the front part of the frame 1 is fixedly connected with an electric slide rail 17 symmetrically distributed along the left and right sides of the frame 1, and a pushing frame 14 is slidably connected between the electric slide rails 17 symmetrically distributed along the front and rear directions, and a plurality of smooth small rollers can be installed at the contact portion of the pushing frame 14 with the top cardboard to reduce the friction between the cardboard and the pushing frame 14, and to limit the cardboard in transportation from above, and the middle of the pushing frame 14 is rotatably connected to a limiting rotating frame 15, and the rear side of the limiting rotating frame 15 is fixedly connected with a pressing plate 16, and the upper part of the frame 1 is fixedly connected with a rotating frame 16 along the frame A guide frame 18 is symmetrically distributed on the left and right sides, and a circular groove is opened on the guide frame 18. The guide frame 18 is slidably connected to the moving frame 19 in the front and rear directions. A first support frame 110 is fixedly connected to the middle of the pushing frame 14, and the first support frame 110 is slidably connected to the moving rod 111 in the up and down directions. Two first telescopic rods 112 are fixedly connected to the front and back sides of the guide frame 18, and an inclined block 113 is fixedly connected between the telescopic ends of adjacent first telescopic rods 112. The upper part of the moving rod 111 is fixedly connected to a sliding rod 114 symmetrically distributed along the moving rod 111. The sliding rod 114 slides along the circular groove of the adjacent guide frame 18. The sliding rod 114 is slidably connected to the adjacent moving frame 19, and the sliding rod 114 contacts the inclined block 113. A convex rod 115 is fixedly connected to the rear side of the pressing plate 16, and the convex rod 115 is movably connected to the moving rod 111.

[0038] First, the cardboard to be cut is stacked and placed on the front side of the placing plate 13, and the front side of the cardboard is in contact with the limiting rotating frame 15. Then, the electric slide rail 17 is started to drive the pushing frame 14 to move backward, so that the limiting rotating frame 15, the pressing plate 16, the moving frame 19, the first supporting frame 110, the moving rod 111, the sliding rod 114 and the protruding rod 115 move backward as a whole, and the sliding rod 114 slides backward along the upper side of the circular groove of the guide frame 18. In this way, the limiting rotating frame 15 pushes the stacked cardboard backward smoothly to the bottom of the cutting assembly 11.

[0039] When the sliding rod 114 contacts the inclined block 113 on the rear side, the sliding rod 114 squeezes the inclined block 113 on the rear side to move upward, and the first telescopic rod 112 on the rear side is compressed. When the sliding rod 114 moves backward to the turning point, the first telescopic rod 112 on the rear side is reset to drive the inclined block 113 on the rear side to move downward, thereby squeezing the sliding rod 114 to slide downward to the lower side of the circular groove of the guide frame 18, thereby driving the moving rod 111 to move downward, and the moving rod 111 squeezes the pressure plate 16 through the convex rod 115 to swing downward, thereby driving the limiting rotating frame 15 to swing upward. In this way, when the limiting rotating frame 15 moves forward and resets, the new cardboard on the front side of the placement plate 13 can be avoided, and the next batch of cardboards to be cut can be placed on the front side of the placement plate 13 without affecting the placement of the next batch of cardboards to be cut on the front side of the placement plate 13;

[0040] Next, the electric slide rail 17 drives the push frame 14 to move forward, so that the limit rotating frame 15, the pressure plate 16, the moving frame 19, the first supporting frame 110, the moving rod 111, the sliding rod 114 and the protruding rod 115 move forward as a whole, and the sliding rod 114 slides forward along the lower side of the circular groove of the guide frame 18;

[0041] When the push frame 14 is separated from the cardboard directly below the cutting assembly 11, the cutting assembly 11 is controlled to drive the clamping assembly 12 to press downward on the top of the topmost cardboard, and the cutting assembly 11 cuts the cardboard downward. When the sliding rod 114 contacts the inclined block 113 on the front side, the sliding rod 114 squeezes the inclined block 113 on the front side to move downward, and the first telescopic rod 112 on the front side is compressed. When the sliding rod 114 moves forward to the turning point, the first telescopic rod 112 on the front side is reset to drive the inclined block 113 on the front side to move upward, thereby squeezing the sliding rod 114 to slide upward to the upper side of the circular groove of the guide frame 18, and then driving the moving rod 111 to move upward. The moving rod 111 toggles the pressing plate 16 upward to swing back to reset through the convex rod 115, thereby driving the limiting rotating frame 15 to swing back to reset downward. In this way, the limiting rotating frame 15 limits the front side of the next batch of cardboards to be cut pushed from the shaping area.

[0042] Embodiment 2: Based on embodiment 1, Figures 8 to 11As shown, it also includes a first connecting frame 2 that is symmetrically distributed along the pushing frame 14, the first connecting frame 2 is fixedly connected to the pushing frame 14, the rear side of the first connecting frame 2 is fixedly connected to two second telescopic rods 21, and the telescopic ends of adjacent second telescopic rods 21 are fixedly connected to a second connecting frame 22, the rear side of the frame 1 is fixedly connected to a tooth plate 23 that is symmetrically distributed along the frame 1, the rear side of the second connecting frame 22 is fixedly connected to a first mounting frame 24, and the first mounting frame 24 is slidably connected to four longitudinally distributed top blocks 25 in the left and right directions, and the top blocks 25 move backwards to squeeze with the adjacent tooth plates 23 Press-fit, elastic components 26 symmetrically distributed along the front and back of the top blocks 25 are fixedly connected between adjacent top blocks 25 and first mounting frames 24, two ends of the elastic components 26 are respectively fixedly connected to the adjacent top blocks 25 and the first mounting frames 24, the top blocks 25 are fixedly connected to third telescopic rods 27 symmetrically distributed along the front and back of the top blocks 25, push blocks 29 are fixedly connected between adjacent third telescopic rods 27, the push blocks 29 are set to be made of rubber material, and the push blocks 29 are used to flatten the left and right sides of the cardboard, and spring pieces 28 symmetrically distributed along the front and back of the adjacent top blocks 25 are fixedly connected between adjacent top blocks 25 and push blocks 29.

[0043] The push frame 14 moves backwards, driving the first connecting frame 2 to move backwards synchronously, and the second telescopic rod 21 is compressed. When the second telescopic rod 21 is compressed to the extreme, the cardboard has moved between the left and right tooth plates 23. From this point on, the sliding rod 114 continues to move backwards to push the second telescopic rod 21 to move backwards through the first connecting frame 2, thereby driving the second connecting frame 22 to move backwards, so that the first mounting frame 24, the top block 25, the elastic component 26, the third telescopic rod 27, the spring piece 28 and the push block 29 start to move backwards synchronously with the cardboard;

[0044] During the backward movement of the top block 25, due to the intermittent squeezing effect of the tooth plate 23 and the elastic force of the elastic component 26, the top block 25 intermittently pushes the push block 29 to slide left and right through the third telescopic rod 27 and the spring sheet 28. In this way, when the cardboard is transported to the rear side of the frame 1, the push block 29 starts to intermittently push the left and right sides of the cardboard, so that the stacked cardboard is aligned in the left and right directions, preventing the left and right sides of the stacked cardboard from being misaligned up and down during cutting. If the push block 29 cannot push the cardboard, in order to prevent the tooth plate 23 from squeezing the top block 25 hard, at this time, the third telescopic rod 27 and the spring sheet 28 play a buffering and protective role on the top block 25.

[0045] Embodiment 3: Based on embodiment 2, Figure 12 to Figure 13 As shown, it also includes a second mounting frame 31 that is symmetrically distributed along the frame 1. The second mounting frame 31 is fixedly connected to the frame 1. The second mounting frame 31 is connected to the limiting plate 3 through a rotating rod 32. The limiting plate 3 limits and guides the cardboard pushed backward on the placement plate 13.

[0046] like Fig.14As shown, it also includes a second support frame 41 symmetrically distributed along the frame 1. The second support frame 41 is fixedly connected to the middle of the frame 1. Four smooth pressing wheels 4 are rotatably connected to the second support frame 41. The pressing wheels 4 press on the top of the topmost cardboard to assist the cardboard to be transported backward stably.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
