Description

Technical Field

[0001] The present invention relates to the technical field of acrylic sheet production, and specifically, it is an extrusion device for producing acrylic sheets. Background Art

[0002] Acrylic sheet is a high-performance transparent organic glass material with high light transmittance, good visual effect, not prone to yellowing, embrittlement or aging after long-term outdoor use, high safety, and at the same time, its density is only half of that of glass, with light self-weight, facilitating transportation and installation, and is widely used in multiple fields;

[0003] According to different production methods, acrylic sheets are mainly divided into casting sheets and extrusion sheets. In the production process of acrylic extrusion sheets, it is necessary to first use an extruder to melt and extrude the raw materials, and then use multiple extrusion rollers to extrude the melted raw materials to plasticize the acrylic sheets;

[0004] After the raw materials melted at high temperature are plasticized, they still remain at a certain temperature and are prone to deformation or shrinkage. Therefore, after the acrylic sheets are extruded and plasticized, they need to be cooled in time. In order to improve the cooling efficiency, cooling water is usually sprayed on the surface of the acrylic sheets to cool them. However, after cooling, the cooling water on the acrylic sheets cannot be wiped off in time, and the un-wiped water will leave obvious water stain marks on the surface of the acrylic sheets, affecting the smoothness and beauty of the sheet surface, and at the same time, it will also affect the subsequent processing quality, resulting in an impact on the overall performance of the acrylic sheets.

[0005] Therefore, those skilled in the art have provided an extrusion device for producing acrylic sheets to solve the problems raised in the above background art. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. Through the design of the water absorption assembly, when in use, when the acrylic board enters the fixed box, the water absorption sponge can quickly absorb the water on the acrylic board. When one water absorption sponge is full of water, the fourth servo motor is started, and the connecting plate is driven to rotate through the rotating shaft, so as to quickly switch the positions of the two water absorption sponges, ensuring that there is always a dry water absorption sponge for water absorption work, and greatly improving the water removal efficiency;

[0023] Meanwhile, during the upward movement of the water-absorbing sponge saturated with water, it will enter the water-squeezing plate, causing the water in the water-absorbing sponge to be squeezed out and collected in the water collection tank, realizing the reuse of the water-absorbing sponge and reducing the production cost.

[0024] In addition, during the switching process of the water-absorbing sponge, through the cooperation of the rotating shaft, connecting rod, abutting rod and the limiting inclined plane, the water-absorbing sponge can still be in contact with the acrylic plate for a period of time during the switching process, absorbing the water on a section of the acrylic plate passing under the scraper during the downward movement of the scraper, ensuring the comprehensiveness and thoroughness of water removal from the acrylic plate.

[0025] 2. In the present invention, the water-blocking component plays an important role during the switching of the two water-absorbing sponges. When the two water-absorbing sponges are switched, the fourth servo motor can drive the incomplete gear to rotate simultaneously, pushing the transmission rack and the sliding rod downward, causing the scraper to move downward and abut against the acrylic plate to block the water on the acrylic plate. When the water-absorbing sponge is completely flipped, under the action of the resilience of the tension spring, the sliding rod drives the scraper to move upward and reset, and the water on the acrylic plate continues to be absorbed by the water-absorbing sponge. This design avoids water remaining on the acrylic plate during the gap period of switching between the two water-absorbing sponges, ensures the stability of the water removal effect, and effectively guarantees the quality of the acrylic plate.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the 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 orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0040] Example 1, please refer to Figures 1-11, An extrusion device for producing acrylic plates, comprising a first frame 1 and a second frame 2. Above the first frame 1, there is a raw material extrusion component 3 for processing and extruding acrylic raw materials. A processing component for processing the acrylic plates produced by the raw material extrusion component 3 is fixedly connected to the first frame 1 and the second frame 2. The processing component includes an extrusion and plasticizing component 4 fixedly connected to the first frame 1, a cooling mechanism fixedly connected between the first frame 1 and the second frame 2 for cooling the acrylic plates, a water absorption component 5 and a cutting component 6 fixedly connected to the second frame 2. Among them, the extrusion and plasticizing component 4 is directly below the discharge end of the raw material extrusion component 3. A water blocking component 7 for assisting the water absorption component 5 to work is slidably connected to one side of the water absorption component 5 close to the extrusion and plasticizing component 4. An auxiliary water removal component 8 is also fixedly connected to the inner wall of the water absorption component 5. Conveyor belts are rotatably connected in both the first frame 1 and the second frame 2. A first servo motor 16 and a second servo motor 21 for controlling the start of the conveyor belts are respectively fixedly connected to one side of the first frame 1 and the second frame 2. A discharge plate 23 for assisting the discharge of acrylic plates is also fixedly connected to one end of the second frame 2 away from the first frame 1. A cutting groove 22 for the cutting component 6 to cut the acrylic plates is also provided on the conveyor belt located on the second frame 2;

[0041] When producing acrylic plates, first, the raw materials are conveyed into the raw material extrusion component 3 through a feeding mechanism (such as a feeding auger). The raw material extrusion component 3 heats and melts the raw materials and extrudes the melted raw materials. The extruded raw materials fall onto the extrusion and plasticizing component 4, and the extrusion and plasticizing component 4 extrudes and plasticizes them. The plasticized acrylic plates move in the direction of the second frame 2 under the drive of the conveyor belt on the first frame 1;

[0042] When the acrylic plates are moving, they will first pass through the cooling mechanism. Under the action of the cooling mechanism, the temperature of the acrylic plates drops and they are shaped. The cooled acrylic plates continue to move and move to the water absorption component 5, and the water absorption component 5 wipes off the remaining water on the acrylic plates to avoid leaving water marks on the acrylic plates and affecting the quality of the finished products;

[0043] The acrylic plates processed by the water absorption component 5 move in the direction of the cutting component 6 under the drive of the conveyor belt on the second frame 2. The cutting component 6 cuts off the excess waste materials at the edges. The cut waste materials and the acrylic plates fall together through the discharge plate 23 and are collected separately, completing the production of acrylic plates.

[0044] Example two, please refer to Figures 1-11, the raw material extrusion assembly 3 includes an extruder 31. One side of the top of the first frame 1 close to the extruder 31 is fixedly connected with a support frame 17. The bottom of the extruder 31 is fixed to the top of the support frame 17. The feeding end of the extruder 31 is fixedly connected with a feeding port 32. One end of the extruder 31 close to the feeding port 32 is fixedly connected with a third servo motor 36. The output end of the third servo motor 36 is fixedly connected with a feeding screw through a coupling, and the feeding screw is rotatably connected inside the extruder 31. The bottom of the extruder 31 is also fixedly connected with multiple heaters 33 for heating the raw materials. The discharging end of the extruder 31 is fixedly connected with a connecting pipe 34. The bottom of the connecting pipe 34 is fixedly connected with an extrusion die 35, and both the connecting pipe 34 and the extrusion die 35 are communicated with the extruder 31. The discharging port of the extrusion die 35 is located directly above the extrusion and plasticizing assembly 4. The extrusion and plasticizing assembly 4 includes two extrusion rollers 41 rotatably connected between the support frames 17. One side of the support frame 17 is fixedly connected with a driving motor for driving the extrusion rollers 41 to rotate. Two auxiliary plasticizing rollers 42 are also rotatably connected between the support frames 17, and the two auxiliary plasticizing rollers 42 are located directly below the two extrusion rollers 41;

[0045] During use, first add the raw materials into the feeding port 32, and start the third servo motor 36 to drive the feeding screw inside the extruder 31 to rotate. When the feeding screw rotates, it continuously conveys the raw materials. At the same time, start multiple heaters 33 on the extruder 31 to heat the extruder 31 through the multiple heaters 33, melting the raw materials inside the extruder 31. Under the action of the feeding screw, the melted raw materials are conveyed into the connecting pipe 34. The raw materials enter the extrusion die 35 through the connecting pipe 34 and are finally extruded through the extrusion die 35;

[0046] The extruded raw materials fall between the two extrusion rollers 41. The two extrusion rollers 41 rotate driven by the driving motor to extrude the raw materials, making the raw materials plasticized into an acrylic board. The plasticized acrylic board falls onto the conveyor belt on the first frame 1 with the assistance of the two auxiliary plasticizing rollers 42 and enters the processing assembly through the conveyance of the conveyor belt for subsequent processing work.

[0047] Example three, please refer to Figures 1-11, the temperature reduction mechanism includes a temperature reduction box 11 fixedly connected between the first frame 1 and the second frame 2. A water collection tank 12 is provided in the temperature reduction box 11. A connecting pipe 13 is communicated in the water collection tank 12. The other end of the connecting pipe 13 is communicated with the cutting assembly 6. One end of the connecting pipe 13 close to the water collection tank 12 is fixedly connected with a water pump. The top of the inner wall of the water collection tank 12 is fixedly connected with a water storage tank 14. The bottom of the water storage tank 14 is fixedly connected with a plurality of spray heads 15, and the plurality of spray heads 15 are all communicated with the water storage tank 14. The water inlet end of the water storage tank 14 is communicated with an external water source through a water pipe. The water absorption assembly 5 includes a fixed box 51. The fixed box 51 is fixedly connected to the second frame 2. A connecting plate 55 is rotatably connected in the fixed box 51, and the connecting plate 55 is located outside the conveyor belt on the second frame 2. Two limiting chutes 56 are provided on the connecting plate 55. Two rotating shafts 57 are respectively slidably connected in the two limiting chutes 56. Two reset springs are also fixedly connected in the two limiting chutes 56, and the other ends of the two reset springs are fixed to the adjacent rotating shafts 57. The other ends of the two rotating shafts 57 are slidably connected to the inner wall of the fixed box 51. Water absorption sponges 58 are sleeved on the two rotating shafts 57. A fourth servo motor 53 is also fixedly connected to the outer side wall of the fixed box 51. The output end of the fourth servo motor 53 is fixedly connected with a rotating shaft 54 through a coupling. The other end of the rotating shaft 54 is fixed to the connecting plate 55. One side of the inner wall of the fixed box 51 is also fixedly connected with a water collection tank 52. A water squeezing plate 59 is also fixedly connected to the inner wall of the fixed box 51 away from the auxiliary water removal assembly 8, and the water squeezing plate 59 is located directly above the water collection tank 52;

[0048] When the acrylic plate enters the processing assembly, it will first enter the temperature reduction box 11. At this time, the external water source is turned on, so that water enters the spray heads 15 through the water storage tank 14 and is sprayed on the acrylic plate to cool the acrylic plate. Through the arranged multiple spray heads 15, during cooling, the acrylic plate can be evenly cooled everywhere, avoiding deformation of the acrylic plate;

[0049] The cooled acrylic plate moves out of the temperature reduction box 11 and moves towards the water absorption assembly 5. When the acrylic plate enters the fixed box 51, it will first contact one of the water absorption sponges 58. The water on the acrylic plate is absorbed by the water absorption sponge 58. The acrylic plate after water removal enters the cutting assembly 6 for cutting work;

[0050] When carrying out the water removal work on the acrylic plate, when one of the water absorption sponges 58 is full of water, the fourth servo motor 53 is started. The fourth servo motor 53 drives the connecting plate 55 to rotate through the rotating shaft 54, so that the positions of the two water absorption sponges 58 are changed, so that the dry water absorption sponge 58 above moves down for water absorption work, and the water absorption sponge 58 full of water moves to the upper part;

[0051] When the water-absorbing sponge 58 full of water moves upward, it will gradually enter the water-squeezing plate 59. Under the action of the water-squeezing plate 59, the water in the water-absorbing sponge 58 is squeezed out. At the same time, since the water-squeezing plate 59 is located above the water collection tank 52, the squeezed water will slide along the water-squeezing plate 59 and fall into the water collection tank 52.

[0052] Embodiment 4, please refer to Figures 1-7 , the auxiliary water removal assembly 8 includes a fixed column 81 fixedly connected to the inner wall of one side of the fixed box 51. A limiting inclined surface 82 is provided on the side of the fixed column 81 close to the water collection tank 52. The auxiliary water removal assembly 8 further includes two groups of connecting rods 83. One ends of the two groups of connecting rods 83 are respectively hinged to the adjacent rotating shafts 57 through rotating shafts. The other ends of the two connecting rods 83 are respectively hinged with auxiliary sliding rods 85 through rotating shafts. And one end of the auxiliary sliding rod 85 close to the connecting plate 55 is slidably connected to the connecting plate 55. The other ends of the two auxiliary sliding rods 85 away from the connecting plate 55 are respectively fixedly connected with abutting rods 84. And the other ends of the two abutting rods 84 away from the connecting rods 83 are both abutted against the limiting inclined surface 82;

[0053] When the fourth servo motor 53 drives the two water-absorbing sponges 58 to switch, the two rotating shafts 57 drive the two connecting rods 83 and the abutting rods 84 to rotate simultaneously. When the abutting rod 84 rotates, the abutting rod 84 connected to the lower water-absorbing sponge 58 is limited by the limiting inclined surface 82 when rotating and pushes the connecting rod 83 to flip towards the direction close to the connecting plate 55. Driven by the connecting rod 83, the rotating shaft 57 slides downward along the limiting sliding groove 56, so that during the flipping process of the connecting plate 55, the lower water-absorbing sponge 58 still remains in contact with the acrylic plate for a period of time, ensuring the water absorption effect on the acrylic plate. During the sliding process of the rotating shaft 57 along the limiting sliding groove 56, the return spring is compressed at the same time, so that the return spring is compressed and stores energy;

[0054] During the downward movement of the upper water-absorbing sponge 58, the return spring between the rotating shaft 57 and the limiting sliding groove 56 drives the rotating shaft 57 to slide in the limiting sliding groove 56. When the rotating shaft 57 slides, it simultaneously pushes the connecting rod 83 to extend outwards. The connecting rod 83 pushes the abutting rod 84 to move, so that the abutting rod 84 extends towards the direction of the fixed column 81, so that the abutting rod 84 is always abutted against the limiting inclined surface 82 until the water-absorbing sponge moves to contact the acrylic plate. After moving in place, the fourth servo motor 53 is turned off, and the lower water-absorbing sponge 58 performs the water absorption work;

[0055] During the switching process of the two water-absorbing sponges 58, through the limitation of the auxiliary sliding rod 85, the abutting rod 84 can always be kept in a horizontal state, making the adjustment of the water-absorbing sponge 58 more stable and accurate.

[0056] Embodiment 5, please refer to Figures 1-7, the water blocking assembly 7 includes two sets of fixing cylinders 71 fixedly connected to the fixing box 51. A sliding rod 72 is slidably connected in each of the two fixing cylinders 71. A scraping plate 73 is fixedly connected between the two sliding rods 72. At the top of each of the two sliding rods 72, a tension spring 76 is fixedly connected. The other ends of the two tension springs 76 are respectively fixedly connected in the adjacent fixing cylinders 71. On one side of one of the sliding rods 72 close to the fixing box 51, a transmission rack 75 is also fixedly connected. The transmission rack 75 is slidably connected to the inner wall of the fixing box 51. An incomplete gear 74 is also fixedly connected to the rotating shaft 54, and the teeth on the incomplete gear 74 are engaged with the transmission rack 75;

[0057] When starting the fourth servo motor 53 to replace the positions of the two 58s, the fourth servo motor 53 simultaneously drives the incomplete gear 74 to rotate. When the incomplete gear 74 rotates, it first meshes with the transmission rack 75 and pushes the transmission rack 75 downward. The transmission rack 75 simultaneously drives the sliding rod 72 downward, so that the scraping plate 73 moves downward to abut against the acrylic plate, and the water on the acrylic plate is blocked by the scraping plate 73. When the 58 is completely flipped, the incomplete gear 74 simultaneously rotates to no longer mesh with the transmission rack 75. At this time, under the action of the resilience of the two tension springs 76, the two sliding rods 72 move upward to reset, and the sliding rod 72 drives the scraping plate 73 to move upward and no longer contact the acrylic plate, and the water on the acrylic plate continues to be absorbed by the 58;

[0058] By providing the water blocking assembly 7 and the auxiliary water removal assembly 8, when the two water absorbing sponges 58 are switched, the water on the acrylic plate can be temporarily blocked by the scraping plate 73, so that the water absorbing sponge 58 can be switched without stopping the machine, ensuring the water removal effect while ensuring the working efficiency, and avoiding water remaining on the acrylic plate during the switching period of the two 58s. At the same time, by providing the water squeezing assembly 8, after the scraping plate 73 moves downward, the water absorbing sponge 58 still contacts the acrylic plate for a period of time, and absorbs the water on a section of the acrylic plate passing under the scraping plate 73 during the downward movement of the scraping plate 73, ensuring the comprehensiveness and thoroughness of the water removal of the acrylic plate.

[0059] Example six, please refer to Figure 1 、 Figure 2 and Figure 8, the cutting assembly 6 includes a cutting box 61, the cutting box 61 is fixedly connected to the second frame 2, one side of the cutting box 61 is fixedly connected with a fifth servo motor 62, the output end of the fifth servo motor 62 is fixedly connected with a synchronous shaft 65 through a coupling, and the synchronous shaft 65 is rotatably connected in the cutting box 61. There are also two fixed shafts 63 arranged in the cutting box 61, and cutting knives 64 are rotatably connected in both of the two fixed shafts 63. The synchronous shaft 65 sequentially passes through the two cutting knives 64 and is fixed to the two cutting knives 64. The bottom of the cutting box 61 is also fixedly connected with two spraying pipes 66, the water outlet ends of the two spraying pipes 66 face the adjacent cutting knives 64 respectively, and the water inlet ends of the two spraying pipes 66 are both communicated with the communicating pipe 13;

[0060] When the processed acrylic board passes through the cutting assembly 6, start the fifth servo motor 62, so that the fifth servo motor 62 drives the two cutting knives 64 to rotate through the synchronous shaft 65, and cut the acrylic board by the rotation of the two cutting knives 64, and cut off the redundant waste materials at the edge of the acrylic board;

[0061] At the same time, when cutting the waste materials, start the water pump on the communicating pipe 13 at the same time, so that the water pump transports the water in the water collecting tank 12 to the spraying pipes 66 through the communicating pipe 13 and sprays it out, so that the water is sprayed on the cutting knives 64 to cool the contact part between the cutting knives 64 and the acrylic board, and avoid the acrylic board edge from melting and deforming due to the high-speed rotation of the cutting knives 64.

[0062] The working principle of the present invention is:

[0063] When producing the acrylic board, first, the raw materials are transported into the feeding port 32 through the feeding mechanism, and start the third servo motor 36, so that the third servo motor 36 drives the feeding screw in the extruder 31 to rotate, continuously transport the raw materials, and at the same time start the multiple heaters 33 on the extruder 31, heat the extruder 31 through the multiple heaters 33, melt the raw materials in the extruder 31, and transport the melted raw materials into the connecting pipe 34 under the action of the feeding screw, and extrude through the extrusion die 35;

[0064] The extruded raw materials fall between the two extrusion rollers 41, and the two extrusion rollers 41 rotate driven by the driving motor to extrude the raw materials, so that the raw materials are plasticized into an acrylic board. The plasticized acrylic board falls on the conveyor belt on the first frame 1 with the assistance of the two auxiliary plasticizing rollers 42, and enters the processing assembly through the conveyor belt for subsequent processing work;

[0065] When the acrylic board enters the processing assembly, it will first enter the cooling box 11. At this time, open the external water source, so that the water is sprayed on the acrylic board to cool the acrylic board. Through the arranged multiple spray heads 15, the acrylic board can be evenly cooled everywhere during cooling, and the acrylic board can be prevented from deforming;

[0066] The acrylic board after temperature reduction is removed from the temperature reduction box 11 and moves towards the water absorption component 5. When the acrylic board enters the fixed box 51, it will first come into contact with one group of water absorption sponges 58, and the water on the acrylic board is absorbed by the water absorption sponges 58. After the water is removed, the acrylic board enters the cutting component 6 for cutting work;

[0067] When carrying out the water removal work on the acrylic board, when one of the water absorption sponges 58 is full of water, the fourth servo motor 53 is started. The fourth servo motor 53 drives the connecting plate 55 to rotate through the rotating shaft 54, so that the positions of the two water absorption sponges 58 are changed, and the dry water absorption sponge 58 above moves down for water absorption work, and the water absorption sponge 58 full of water moves to the upper part;

[0068] When the water absorption sponge 58 full of water moves upward, it will gradually come into contact with the water squeezing plate 59, and the water in the water absorption sponge 58 is squeezed out under the action of the water squeezing plate 59. At the same time, since the water squeezing plate 59 is located above the water collecting tank 52, the squeezed water will slide down along the water squeezing plate 59 and fall into the water collecting tank 52;

[0069] When the lower 58 is full of water, the fourth servo motor 53 is started again, so that the connecting plate 55 drives the positions of the two 58 to be switched, and the above work is repeated to realize the water removal work on the surface of the acrylic board;

[0070] When the fourth servo motor 53 drives the two water absorption sponges 58 to be switched, the two rotating shafts 57 drive the two connecting rods 83 and the abutting rods 84 to rotate at the same time. When the abutting rod 84 rotates, the abutting rod 84 connected to the lower water absorption sponge 58 is limited by the limiting inclined surface 82 and pushes the connecting rod 83 to flip towards the direction close to the connecting plate 55. Driven by the connecting rod 83, the rotating shaft 57 slides down along the limiting sliding groove 56, so that during the flipping process of the connecting plate 55, the lower water absorption sponge 58 still keeps in contact with the acrylic board for a period of time, ensuring the water absorption effect on the acrylic board;

[0071] When starting the fourth servo motor 53 to replace the positions of the two 58, the fourth servo motor 53 drives the incomplete gear 74 to rotate at the same time. The incomplete gear 74 meshes with the transmission rack 75 and pushes the transmission rack 75 to move down. The transmission rack 75 drives the sliding rod 72 to move down at the same time, so that the scraping plate 73 moves down to abut against the acrylic board, and the water on the acrylic board is blocked by the scraping plate 73. When the 58 is completely flipped, the incomplete gear 74 rotates to no longer mesh with the transmission rack 75 at the same time. At this time, under the action of the resilience of the two tension springs 76, the two sliding rods 72 move up and reset, so that the sliding rods 72 drive the scraping plate 73 to move up and no longer contact the acrylic board, and the water on the acrylic board continues to be absorbed by the 58;

[0072] Through the provided water-blocking component 7, when switching between two [58s], the squeegee 73 can temporarily block the water on the acrylic plate at the same time, ensuring the water removal effect and preventing water from remaining on the acrylic plate during the gap period of switching between the two [58s]. Additionally, through the setting of the water-squeezing component 8, after the squeegee 73 moves downward, the water-absorbing sponge 58 still contacts the acrylic plate for a period of time to absorb the water on a section of the acrylic plate passing under the squeegee 73 during the downward movement of the squeegee 73, ensuring the comprehensiveness and thoroughness of water removal from the acrylic plate;

[0073] When the processed acrylic plate passes through the cutting component 6, the fifth servo motor 62 is started, and the fifth servo motor 62 drives the two cutting knives 64 to rotate through the synchronous shaft 65. The acrylic plate is cut by the rotation of the two cutting knives 64 to remove the excess waste material from the edge of the acrylic plate.

Moreover, the circuit connection relationships of each device all belong to simple series and parallel connection circuits, and there is no innovation point in the circuit connection part.
