Description

Technical Field

[0001] The invention belongs to the technical field of plastic molding, and in particular relates to a casting machine which is convenient for cleaning a scraper. Background Art

[0002] A cast tape machine is a molding device used to manufacture films or thin plates. When producing films, roller extrusion is mostly used. When producing thin plates, a scraper is mostly used to control the product thickness. In addition to the complex structure, high cost and high failure rate of the current cast tape machines, the scrapers also need to be manually replaced and cleaned at regular intervals, which is time-consuming and labor-intensive.

[0003] The reason why the scraper can control the thickness of the product is that it can spread the material and control the thickness of the viscous material according to the gap between itself and the bottom surface of the feeder. The material has poor wettability to a clean scraper, but with the increase of usage time, on the one hand, the bottom of the scraper is prone to material adhesion, which reduces the actual equivalent gap between the scraper and the bottom surface of the feeder. On the other hand, as the material adheres to the back of the scraper, the viscosity between the materials will also affect the thickness of the product, so it needs to be replaced and cleaned.

[0004] This process is currently mostly done manually, so the frequency of replacement is limited. Summary of the invention

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are 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 direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0047] like Figure 1 to Figure 11 As shown, the present invention proposes a casting machine which is convenient for cleaning a scraper, comprising an intermittent scraper twisting mechanism 1, a reciprocating limit cleaning mechanism 2, a main frame mechanism 3 and a slope casting mechanism 4, wherein the intermittent scraper twisting mechanism 1 is arranged on the main frame mechanism 3, the reciprocating limit cleaning mechanism 2 is arranged on the main frame mechanism 3, and the slope casting mechanism 4 is arranged on the main frame mechanism 3.

[0048] The main frame mechanism 3 includes a frame assembly 35 and a casting control assembly 36. The frame assembly 35 includes a main base plate 37, an extended table plate 38 and an I-shaped bracket 39. The extended table plate 38 is arranged on the main base plate 37, the I-shaped bracket 39 is arranged on the main base plate 37, and the casting control assembly 36 is arranged on the main base plate 37.

[0049] Since the various moving components are connected in a linkage manner, not only can the structure be simplified, but the operating speed of the inclined casting belt 55, the rotation frequency of the scraper mounting shaft 9 and the reciprocating sliding frequency of the reciprocating limiting cleaning mechanism 2 can also change with the change of the unloading speed. By replacing the material roller pulley 43 and the material roller transmission belt 44 of different specifications, the transmission ratio between the unloading roller body 42 and the first belt roller body 53 can be changed, thereby creating conditions for adjusting the product thickness.

[0050] The casting control assembly 36 includes a feed trough 40, a feed roller bracket 41, a feed roller body 42, a feed roller pulley 43 and a feed roller drive belt 44. The feed trough 40 is arranged on an I-shaped bracket 39. A drooping baffle 45 is provided on the feed trough 40. Vertical baffles 46 and baffle mounting portions 47 are symmetrically provided on both sides of the drooping baffle 45.

The feed roller body 42 is rotatably arranged in the feed roller bracket 41. The feed roller body 42 is evenly distributed with a feed roller groove portion 48 in an annular manner. The feed roller pulley 43 is clamped on the feed roller body 42. The feed roller drive belt 44 is arranged between the feed roller pulley 43 and the slope casting mechanism 4.

[0051] The slope casting mechanism 4 includes a belt roller assembly 49 and a drying and forming assembly 50. The drying and forming assembly 50 includes an inclined casting belt 55 and a drying device 56. The drying device 56 is arranged between the scraper shaft bracket 8. The inclined casting belt 55 and the drying device 56 are parallel to each other.

[0052] The belt roller assembly 49 includes a first belt roller bracket 51, a second belt roller bracket 52, a first belt roller body 53 and a second belt roller body 54. The first belt roller bracket 51 and the second belt roller bracket 52 are arranged on the main body bottom plate 37, the first belt roller body 53 is rotatably arranged on the first belt roller bracket 51, the second belt roller body 54 is rotatably arranged on the second belt roller bracket 52, the inclined cast belt 55 is arranged between the first belt roller body 53 and the second belt roller body 54, the driving belt 32 is arranged between the driving nut 31 and the material roller pulley 43, the material roller transmission belt 44 is arranged between the material roller pulley 43 and the first belt roller body 53, and the torsion pulley 16 is engaged with the second belt roller body 54.

[0053] The intermittent scraper twisting mechanism 1 includes a combined scraper assembly 5, a positioning assembly 6 and a torque applying assembly 7. The combined scraper assembly 5 is arranged on the main body bottom plate 37, the positioning assembly 6 is arranged on the combined scraper assembly 5, and the torque applying assembly 7 is arranged on the main body bottom plate 37.

[0054] The intermittent scraper twisting mechanism 1 can cause the combined scraper assembly 5 to rotate intermittently periodically during the continuous operation of the device, thereby achieving the technical purpose of automatically cyclically replacing and cleaning the scraper body 10.

[0055] The combined scraper assembly 5 includes a scraper shaft bracket 8, a scraper mounting shaft 9, a scraper body 10 and a scraper adjustment disk 11. The scraper shaft bracket 8 is detachably arranged on the main body bottom plate 37. A retaining ring portion 18 is provided on the inner side of the scraper shaft bracket 8. The scraper mounting shaft 9 is rotatably arranged in the scraper shaft bracket 8. A slide groove portion 19 is evenly distributed in an annular shape on the scraper mounting shaft 9. The scraper body 10 is engaged and slidably arranged in the slide groove portion 19. A positioning boss portion 20 is also provided on the end surface of the scraper mounting shaft 9. A positioning cam portion 21 is provided on the end surface of the scraper body 10. The scraper adjustment disk 11 is rotatably arranged at both ends of the scraper mounting shaft 9. A positioning hole 22 matching the positioning boss portion 20 is provided on the scraper adjustment disk 11. An adjustment groove 23 is also provided on the scraper adjustment disk 11. The positioning cam portion 21 is slidably arranged in the adjustment groove 23.

[0056] The scraper body 10 that can rotate periodically can avoid the problem that the back side of the scraper body 10 is easily adhered to the slurry after long-term use, and the problem of reduced product thickness accuracy caused by the problem.

[0057] The positioning assembly 6 includes an elastic stop platform 12 and a positioning snap ring 13. The positioning snap ring 13 is snap-fitted to the end of the scraper mounting shaft 9. Positioning baffles 24 are evenly distributed in a ring on the positioning snap ring 13. The number of positioning baffles 24 is the same as the number of slide grooves 19. The elastic stop platform 12 is fixedly connected to the scraper shaft bracket 8.

[0058] The positioning component 6 can be used to position and limit the scraper mounting shaft 9 when the torque of the torque applying component 7 is small, so that the reciprocating limiting cleaning mechanism 2 can be accurately mounted on the scraper body 10 and clean it. When the torque increases to a level sufficient to cause the elastic stop platform 12 to deform, the reciprocating limiting cleaning mechanism 2 is used to limit the rotation of the scraper mounting shaft 9.

[0059] The torque applying assembly 7 includes a torsion wheel shaft 14, a torsion spring 15, a torsion pulley 16, a torsion transmission belt 17 and a torsion bracket 58. The torsion bracket 58 is arranged on the main body bottom plate 37. The torsion wheel shaft 14 is rotatably arranged in the torsion bracket 58. The two ends of the torsion spring 15 are respectively fixed to the torsion wheel shaft 14 and the scraper mounting shaft 9. The torsion pulley 16 is engaged with the slope casting mechanism 4, and the torsion transmission belt 17 is arranged between the torsion pulley 16 and the torsion wheel shaft 14.

[0060] The working process of the torque applying assembly 7 is actually a process of periodically and reciprocatingly storing and releasing elastic force, so that the scraper mounting shaft 9 can be driven to perform periodic intermittent rotation through the continuously rotating torsion wheel shaft 14.

[0061] The reciprocating position limiting cleaning mechanism 2 comprises a reciprocating sliding assembly 25 and a reciprocating driving assembly 26 . The reciprocating sliding assembly 25 is arranged on the scraper shaft bracket 8 , and the reciprocating driving assembly 26 is arranged on the reciprocating sliding assembly 25 .

[0062] The reciprocating sliding assembly 25 includes a reciprocating bracket 27, a reciprocating member 57 and a frame-type scraper 30. The reciprocating bracket 27 is arranged on the scraper shaft bracket 8. A fork frame portion 33 is provided on the top of the reciprocating bracket 27. A reciprocating screw rod 28 and a guide rod 29 parallel to each other are provided in the middle position of the reciprocating member 57. The guide rod 29 is slidably arranged in the fork frame portion 33. The reciprocating screw rod 28 is slidably arranged in the fork frame portion 33. A follower shaft portion 34 is provided at the bottom of the frame-type scraper 30. The frame-type scraper 30 is rotatably arranged on the reciprocating member 57 through the follower shaft portion 34.

[0063] Through the bidirectional threads on the surface of the reciprocating screw 28, the drive nut 31 can drive the reciprocating member 57 to slide back and forth while rotating continuously in one direction. A rubber sheet or a brush for scraping is provided on the inner wall of the frame scraper 30. Each reciprocating sliding cycle of the frame scraper 30 can clean the scraper body 10 once.

[0064] The reciprocating drive assembly 26 includes a driving nut 31 and a driving belt 32. The driving nut 31 is rotatably arranged in the fork frame part 33. The driving nut 31 and the reciprocating screw rod 28 are threadedly connected. During the continuous rotation of the driving nut 31, the reciprocating member 57 will slide back and forth; the driving belt 32 is arranged between the driving nut 31 and the slope casting mechanism 4.

[0065] like Fig.12 As shown, an external collecting box is placed below the reciprocating limiting cleaning mechanism 2 , and the slope surface of the collecting box is elastic and will not block the rotation of the combined scraper assembly 5 .

[0066] When in use, the user first needs to feed the viscous slurry into the gap between the drooping baffle 45 and the feeding roller body 42 through the feeding trough 40. The two ends of the gap are blocked by the vertical baffles 46, and the material can only fall from the bottom. Since there is a feeding roller groove 48 on the feeding roller body 42, the speed at which the material falls is related to the rotation speed of the feeding roller body 42. Within a certain range, the faster the rotation speed of the feeding roller body 42, the faster the material falls.

[0067] At the same time, the second belt roller body 54 is rotated by an external driving device. When the second belt roller body 54 rotates, the first belt roller body 53 can be rotated together through the inclined casting belt 55. When the second belt roller body 54 rotates, the torsion pulley 16 and the torsion transmission belt 17 can be used to drive the torsion wheel shaft 14 to rotate continuously. In the initial stage of each cycle, since the elastic force of the torsion spring 15 is not enough to deform the elastic stop platform 12, the scraper installation shaft 9 will be stable at the current position. When the elastic force of the torsion spring 15 is enough to deform the elastic stop platform 12 and the scraper body 10 is not stuck by the frame scraper 30, the positioning clamp ring 13 will rotate with the scraper installation shaft 9. During this process, the elastic force of the torsion spring 15 gradually decreases and is not enough to drive the elastic stop platform 12 to deform again.

[0068] When the first belt roller body 53 rotates, it can rotate the unloading roller body 42 through the material roller pulley 43 and the material roller transmission belt 44, and the rotation speed of the unloading roller body 42 can automatically match the rotation speed of the first belt roller body 53;

[0069] After the material flows onto the inclined casting belt 55, it can move toward the scraper body 10 under the combined action of gravity and the inclined casting belt 55. Since the gap between the scraper body 10 and the inclined casting belt 55 is fixed, the material passing through the scraper body 10 will be flattened to a fixed thickness. After drying and shaping by the drying device 56, it can eventually form a thin plate of a certain thickness.

[0070] The first belt roller body 53 rotates while driving the driving nut 31 through the driving belt 32. The driving nut 31 cooperates with the bidirectional threads on the surface of the reciprocating screw 28, so that the driving nut 31 can drive the reciprocating member 57 to slide back and forth when rotating in one direction. A rubber sheet or a brush for scraping is provided on the inner wall of the frame-type scraper 30. Each reciprocating sliding cycle of the frame-type scraper 30 can clean the scraper body 10 once.

[0071] At the same time, since the follower shaft portion 34 is located at one end of the frame-type scraper 30, when the frame-type scraper 30 is slid by the follower shaft portion 34, the angle of the frame-type scraper 30 will change adaptively, so that no matter how long the scraper body 10 extends from the slide groove portion 19, the interior of the frame-type scraper 30 can be completely fitted with the scraper body 10;

[0072] The slurry scraped off by the frame scraper 30 will fall into the external collection box. The frame scraper 30 will not be separated from the scraper body 10 when it turns back. Therefore, during the entire reciprocating sliding cycle of the reciprocating member 57, the frame scraper 30 can prevent the scraper body 10 from rotating. After the frame scraper 30 is separated from the scraper body 10, the elastic force of the torsion spring 15 will overcome the obstruction of the elastic stop table 12 to cause the combined scraper assembly 5 to rotate once a unit angle.

[0073] When the product thickness needs to be changed, on the one hand, the scraper shaft bracket 8 needs to be removed, and the scraper body 10 needs to be pulled out from the positioning boss part 20, rotated and then engaged. At this time, since the positioning hole 22 that cooperates with the positioning boss part 20 has changed, the extension length of each scraper body 10 can be adjusted through the cooperation of the positioning cam part 21 and the adjustment groove 23, thereby changing the gap between the scraper body 10 and the inclined casting belt 55 (that is, the product thickness); at the same time, it is also necessary to replace the material roller pulley 43 and the material roller transmission belt 44 of different specifications, so as to change the unloading speed of the casting control assembly 36 when the movement speed of the inclined casting belt 55 remains unchanged.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0075] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
