Description
Technical Field
[0001] The utility model relates to the technical field of plastic product processing, in particular to a roller-leveling device for plastic products. Background Art
[0002] Plastic is a kind of synthetic polymer material with plasticity. It, together with synthetic rubber and synthetic fiber, forms the three indispensable synthetic materials in daily life. In the production of plastic products, such as plastic plates, flattening equipment is needed to correct their position and flatness for subsequent stacking and cutting.
[0003] However, during flattening, since the plastic plates are pushed into the flattening rollers manually, it is impossible to ensure that the plastic plates are pushed in a vertical state, resulting in the plastic plates being tilted when pushed into the flattening rollers. As a result, when the flattened plastic plates are stacked, it is impossible to ensure that the upper and lower plastic plates are aligned. Since the plastic plates are heated before flattening, if the stacked plastic plates cannot be aligned up and down, the plastic plates cannot be fully supported, resulting in the plastic plates bending downward and deforming. Utility Model Content
[0004] In order to overcome the disadvantage that stacked plastic plates cannot be aligned up and down due to manual pushing, which will result in the plastic plates being unable to be fully supported and further causing the plastic plates to bend and deform downward, the utility model provides a roller leveling device for plastic products.
[0005] The technical solution is: a roller leveling equipment for plastic products, including a support platform, a lifting plate, a heating roller, a flattening roller and a conveying roller; the front and rear of the support platform are each fixedly connected to two lifting plates distributed on the left and right; the two lifting plates on the left side jointly rotate a heating roller; the two lifting plates on the right side jointly rotate a flattening roller; a conveying roller rotates on the right side of the support platform; it also includes a mounting frame, a camera, a driving assembly and a pushing block; the support platform is fixedly connected to the mounting frame; a camera is fixedly connected to each of the two sides of the left part of the mounting frame; the mounting frame is connected to the driving assembly; the driving assembly is connected to two pushing blocks distributed front and back, and the two pushing blocks are driven by the driving assembly to move forward and backward and rotate respectively.
[0006] Furthermore, it also includes a push rod 1 and a clamping block; the two push blocks are each fixedly connected to a push rod 1 on the opposite sides; and each telescopic part of the push rod 1 is each fixedly connected to a clamping block.
[0007] Furthermore, the pushing block and the clamping block are made of silicone.
[0008] Furthermore, it also includes a support frame, a push rod 2, a discharge plate, a push rod 3 and a cooling plate; the support frame is placed on the right side of the support platform; the support frame is fixedly connected to a number of push rods 2; the telescopic parts of all push rods 2 are commonly fixedly connected to the discharge plate; the support frame is fixedly connected to a number of push rods 3; the telescopic parts of all push rods 3 are commonly fixedly connected to the cooling plate; a connecting hole is opened on the upper part of the cooling plate, and a cavity is opened on the cooling plate, and the cavity is connected to the connecting hole.
[0009] Furthermore, a plurality of air jet holes are respectively arranged on both sides of the cooling plate, and the air jet holes are communicated with the cavity.
[0010] Furthermore, it also includes a limiting plate; a limiting plate is slidably connected to each of the two sides of the right part of the support frame.
[0011] The beneficial effects are:
[0012] The camera is used to capture and detect both sides of the plastic plate, so as to analyze the inclination angle of both sides of the plastic plate, and then the pushing block rotates to the same angle as the inclination of the plastic plate, and the pushing block clamps both sides of the inclined plastic plate, and then the pushing block clamps the plastic plate and rotates, so that the plastic plate rotates from an inclined state to a vertical state, thereby preventing the upper and lower plastic plates stacked from overlapping when the inclined state is pushed out, causing the plastic plate to bend again, and pushing the plastic plate straight during the flattening process can avoid the problem of not being able to ensure uniform force when the inclined state is flattened, resulting in poor flattening effect.
[0013] The push rod 1 will push the clamping block down, so that the clamping block and the plastic plate are in close contact, and then the clamping block limits the plastic plate to prevent the plastic plate from being bent and deformed when it is clamped by the pusher block and rotates.
[0014] The cold air enters the cavity, and the cold air will cool down the cooling plate, making the cooling plate in a low temperature state. At this time, the cooling plate will absorb the heat in the plastic plate, so that the plastic plate will cool down quickly, avoiding the plastic plate from rebounding due to high heat, causing it to bend again, thereby greatly reducing the flattening effect.
[0015] The cold air in the cavity will be ejected from the jet holes, and the jet holes are located on both sides of the plastic plate, so that the two sides of the plastic plate can be cooled quickly, thereby avoiding the occurrence of rebound phenomenon. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Example 1
[0023] A roller-leveling device for plastic products, such as Figure 1-4 As shown, it includes a support platform 1, a lifting plate 2, a heating roller 3, a flattening roller 4 and a conveying roller 5; the front and rear parts of the support platform 1 are each fixedly connected with two lifting plates 2 distributed on the left and right; the two lifting plates 2 on the left side rotate a heating roller 3 together; the two lifting plates 2 on the right side rotate a flattening roller 4 together; the conveying roller 5 is rotated on the right part of the support platform 1;
[0024] It also includes a mounting frame 101, a camera 102, a driving assembly and a pusher block 103; the support platform 1 is bolted to the mounting frame 101; a camera 102 is fixedly connected to the left front side and the left rear side of the mounting frame 101; the mounting frame 101 is connected to the driving assembly; the driving assembly is connected to two pusher blocks 103 distributed front and back.
[0025] The driving assembly includes a guide rail 111, a moving block 112, a connecting block 113 and a motor 114; the support table 1 is fixedly connected to the guide rail 111; the front and rear parts of the guide rail 111 are each slidably connected to a moving block 112; each moving block 112 is fixedly connected to a connecting block 113; each connecting block 113 is fixedly connected to a motor 114; and each output shaft of the motor 114 is fixedly connected to a pushing block 103.
[0026] It also includes a push rod 121 and a clamping block 122; each of the two pusher blocks 103 facing each other is fixedly connected with a push rod 121; each telescopic part of each push rod 121 is fixedly connected with a clamping block 122.
[0027] The pushing block 103 and the clamping block 122 are made of silicone material, which increases the friction between the pushing block 103 and the plastic plate, thereby facilitating the rotation of the plastic plate.
[0028] It also includes a support frame 201, a push rod 202, a discharge plate 203, a push rod 3 204 and a cooling plate 205; the support frame 201 is placed on the right side of the support platform 1; the support frame 201 is fixed with four push rods 202 distributed in a rectangular shape; the telescopic parts of all push rods 202 are commonly fixed with the discharge plate 203; the support frame 201 is fixed with four push rods 3 204 distributed in a rectangular shape; the telescopic parts of all push rods 3 204 are commonly fixed with the cooling plate 205; a connecting hole 205a is opened on the upper part of the cooling plate 205, and a cavity 205b is opened on the cooling plate 205, and the cavity 205b is connected with the connecting hole 205a.
[0029] Nine injection holes 205c are respectively provided on the front side and the rear side of the cooling plate 205, and the injection holes 205c are communicated with the cavity 205b.
[0030] It also includes a limiting plate 211; a limiting plate 211 is slidably connected to the right front side and the right rear side of the support frame 201.
[0031] The specific working steps are:
[0032] The external cold air delivery device is connected to the communication hole 205a;
[0033] The plastic sheet is manually pushed between the rotating heating roller 3 and the supporting platform 1, and the heating roller 3 is made to contact with the plastic sheet, so that the heating roller 3 heats and flattens the plastic sheet. It should be noted that the temperature heated by the heating roller 3 will not melt the plastic sheet, but will only soften it, making it easier to be flattened. Then the heating roller 3 pushes the plastic sheet to move to the right and enter the flattening roller 4, so that the rotating flattening roller 4 will flatten the plastic sheet again. Because there will be rebound after the first flattening, the degree of rebound of the plastic sheet can be reduced after the second flattening. Then the flattening roller 4 pushes the plastic sheet to continue to move to the right and enter the conveying roller 5, so that the rotating conveying roller 5 pushes the plastic sheet to move to the right for stacking. When the right part of the plastic sheet just leaves the flattening roller 4, the camera 102 will shoot and detect both sides of the plastic sheet, so as to analyze the inclination angles of both sides of the plastic sheet, and then the motor 114 drives the pushing block 103 to rotate, so that the pushing block 103 rotates at the same angle as the inclination of the plastic sheet, and then The guide rail 111 drives the moving block 112 to drive the pushing block 103 to move towards the plastic plate, so that the two pushing blocks 103 clamp the two sides of the inclined plastic plate, and then the lifting plate 2 drives the heating roller 3 and the flattening roller 4 to rise, so that the heating roller 3 and the flattening roller 4 are no longer in contact with the plastic plate, and then the motor 114 drives the pushing block 103 to clamp the plastic plate and rotate, so that the plastic plate rotates from the inclined state to the vertical state, and then the lifting plate 2 drives the heating roller 3 and the flattening roller 4 to descend and contact the plastic plate, and then the guide rail 111 drives the moving block 112 to drive the pushing block 103 away from the plastic plate, and then the heating roller 3 and the flattening roller 4 continue to rotate, so that the plastic plate is flattened and pushed out in a vertical state, thereby preventing the upper and lower plastic plates stacked in the inclined state from being unable to overlap when being pushed out, causing the plastic plate to bend again, and pushing the plastic plate straight in the flattening process can avoid the problem that the inclined state cannot be flattened and the flattening effect is poor.
[0034] After being flattened, the plastic plate has a certain degree of resilience. At this time, the plastic plate is clamped and rotated by the push block 103, which may cause the plastic plate to bend upward again. Therefore, when the push block 103 contacts the plastic plate, the push rod 121 will push the clamping block 122 down, so that the clamping block 122 is in close contact with the plastic plate, and then the clamping block 122 limits the position of the plastic plate, thereby preventing the plastic plate from bending and deforming when it is clamped and rotated by the push block 103.
[0035] When the plastic plate is flattened and pushed to the right by the conveying roller 5, the plastic plate will move to the upper part of the discharge plate 203. At this time, the push rod 3 204 will push the cooling plate 205 down, so that the cooling plate 205 and the discharge plate 203 cooperate to clamp the plastic plate. At this time, the external cold air conveying equipment will convey cold air to the connecting hole 205a, so that the cold air enters the cavity 205b. At this time, the cold air will cool down the cooling plate 205, so that the cooling plate 205 is in a low temperature state. At this time, the cooling plate 205 will absorb the heat in the plastic plate, so that the plastic plate will cool down quickly, avoiding the rebound of the plastic plate due to high heat, resulting in bending again, thereby greatly reducing the flattening effect;
[0036] Before the next plastic plate is pushed out, the push rod 202 will push the unloading plate 203 down, so that the upper surface of the plastic plate placed on the unloading plate 203 is flush with the support platform 1, and at the same time, the push rod 3 204 drives the cooling plate 205 to rise, and then the next plastic plate is pushed to the upper part of the previous plastic plate, and then the push rod 3 204 drives the cooling plate 205 to descend, so that the cooling plate 205 performs cooling work on the next plastic plate, thereby completing the stacking work of the plastic plates;
[0037] Most of the bending area of the plastic plate is the two side areas, so the cold air in the cavity 205b will be ejected from the jet holes 205c, and the jet holes 205c are located on the two side areas of the plastic plate, so that the two side areas of the plastic plate can be quickly cooled, thereby avoiding the occurrence of the rebound phenomenon;
[0038] It should be noted that when the next plastic plate is pushed onto the previous plastic plate, the next plastic plate is likely to push the previous plastic plate to move, thereby causing the upper and lower plastic plates to be unable to align. At this time, the plastic plate is not limited and is prone to rebound bending. Therefore, the limiting plate 211 will play a blocking role to prevent the next plastic plate from easily pushing the previous plastic plate to move, thereby ensuring that the plastic plates are in an aligned state when stacked. When the plastic plate needs to be taken out, just push the two limiting plates 211 to move to the opposite sides to keep them away from the plastic plates.
[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
