Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE board production technology, and in particular to a thermoplastic machine for PE board production. Background Technology
[0002] PE sheet is a highly crystalline, non-polar thermoplastic resin with good heat and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. During PE sheet production, a heat-shrinkable film is applied to its surface using a thermoplastic machine for protection.
[0003] In the prior art, Chinese patent application number 202420804842.1 discloses a thermoplastic machine for PE board production, belonging to the field of PE board production technology. It includes a conveyor platform and a thermoplastic assembly located on the conveyor platform. A main drive motor is installed on one side wall of the conveyor platform. A conveyor belt, coupled to the main drive motor, runs inside the conveyor platform and is used to transport PE boards. An inverted U-shaped receiving bracket is welded to the center of the top wall of the conveyor platform. A servo motor is horizontally installed on one side wall of the receiving bracket. Movable slots are formed on opposite sides of the receiving bracket, and inner support shafts are rotatably connected to both slots. The output shaft of the servo motor is coaxially connected to one of the inner support shafts. Both the main drive motor and the servo motor require external power supply. This thermoplastic machine for PE board production performs integrated coating and heat shrinking processing on the PE board surface, avoiding the separation of the two processes and thus improving processing efficiency.
[0004] However, the above technical solutions, although they achieve thermoplastic coating of PE sheets, do not have guiding and limiting functions for the PE sheets during conveying. During the conveying of the PE sheets, the PE sheets may tilt or deviate in position, making it impossible for the PE sheets to accurately correspond with the heat shrink film, thus affecting the thermoplastic coating effect. Therefore, this application proposes a thermoplastic machine for PE sheet production to solve the above problems. Utility Model Content

This can cause the PE sheet to tilt or shift during transport, making it impossible for the PE sheet to accurately align with the heat shrink film and affecting the thermoplastic coating effect. Therefore, this invention proposes a thermoplastic machine for PE sheet production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The first electric push rod is configured as four. The two first electric push rods located on the front side are fixedly installed on the front side of the mounting base, and the two first electric push rods located on the rear side are fixedly installed on the rear side of the mounting base. The top of the conveyor belt is slidably connected to two limit strips, and the output shaft of the first electric push rod is fixedly installed on one side of the corresponding limit strip.
[0010] The mounting bracket has two bottom ends fixedly installed on the front and rear sides of the mounting base, respectively, and two mounting slots are provided on the left side of the mounting bracket.

The output shaft of the second electric push rod passes through the mounting bracket and is slidably connected to the mounting bracket. A thermoplastic plate is fixedly installed on the output shaft of the second electric push rod.

Rectangular blocks are fixedly mounted on the right ends of the two rotating shafts and on the output shafts of the two motors. The rollers are positioned in the corresponding mounting slots, with rectangular sleeves fixedly mounted on the left and right ends of the rollers. One end of the rectangular block can be detached and inserted into the corresponding rectangular sleeve. The front and rear ends of the heat shrink film are respectively mounted to the two rollers, and the heat shrink film is located below the thermoplastic sheet.
[0014] As a preferred embodiment of this utility model, a third electric push rod is fixedly installed on both the front and rear sides of the mounting bracket, and the output shafts of the two third electric push rods are respectively fixedly installed on the front and rear sides of the moving rod.

[0032] Conveyor belt 2 is installed inside mounting base 1;
[0033] The first electric push rod 3 is configured as four. The two first electric push rods 3 located on the front side are fixedly installed on the front side of the mounting base 1, and the two first electric push rods 3 located on the rear side are fixedly installed on the rear side of the mounting base 1.

[0036] Shrink film assembly, which is mounted on mounting frame 5 and cooperates with thermoplastic sheet 7.
[0037] With the above structure, by activating the four first electric push rods 3, the two limiting strips 4 on both sides can be moved closer or further apart, thereby limiting the PE board and ensuring that the PE board is transported in the center position of the conveyor belt 2, avoiding the PE board from shifting during transport, and improving the quality of the thermoplastic film coating process of the PE board. In addition, by placing the PE board on the top of the conveyor belt 2 in sequence, activating the conveyor belt 2 can drive the PE board to be transported and moved below the shrink film assembly. At this time, activating the second electric push rod 6 can drive the thermoplastic board 7 to move down and cooperate with the shrink film assembly to perform thermoplastic film coating operation on the PE board.
[0038] As a preferred embodiment of this utility model, the shrink film assembly includes two motors 9, a moving rod 11, two rotating shafts 12, two rollers 13, and a heat shrink film 15. Both motors 9 are fixedly mounted on the right side of the mounting frame 5, with their output shafts passing through one side of the mounting frame 5 and extending into the corresponding mounting groove 8. The moving rod 11 is mounted on the left side of the mounting frame 5, and both rotating shafts 12 are rotatably connected to the right side of the moving rod 11.

The rollers 13 are positioned within the corresponding mounting grooves 8, with rectangular sleeves 14 fixedly mounted on both the left and right ends of the rollers 13. One end of the rectangular block 10 can be detached and inserted into the corresponding rectangular sleeve 14. The heat shrink film... The front and rear ends of the heat shrink film 15 are respectively installed with two rollers 13. The heat shrink film 15 is located below the thermoplastic plate 7. By starting the motor 9, the two rectangular blocks 10 on it can be driven to rotate. At this time, through the insertion limit between the rectangular block 10 and the corresponding rectangular sleeve 14, the rectangular sleeve 14 and the two rollers 13 can be driven to rotate. Here, the rotation of the two rollers 13 is opposite. At the same time, the rear roller 13 is used to install the master roll of the heat shrink film 15 and perform the unwinding operation, while the front roller 13 is used to rewind the edge material of the heat shrink film 15 after use. In this way, the stable output and rewinding of the heat shrink film 15 can be achieved, and it can be used with the thermoplastic plate 7 to perform thermoplastic coating processing on multiple PE boards.
[0039] As a preferred embodiment of this utility model, the mounting frame 5 is fixedly mounted with a third electric push rod 19 on both the front and rear sides. The output shafts of the two third electric push rods 19 are respectively fixedly mounted on the front and rear sides of the moving rod 11. By activating the third electric push rod 19, the moving rod 11 can be driven to move left and right. When the moving rod 11 moves to the left, it can drive the two rotating shafts 12 and the two rectangular blocks 10 on it to move to the left and release the insertion and rotation support of the left end of the two rollers 13. At this time, it is convenient to disassemble the two rollers 13 for easy disassembly and replacement.
[0040] As a preferred embodiment of this utility model, the mounting bracket 5 has an adapter groove on its left side, and the moving rod 11 can be disengaged and inserted into the adapter groove. The adapter groove facilitates the installation between the moving rod 11 and the mounting bracket 5.
[0041] As a preferred embodiment of this utility model, two stabilizing rods 20 are fixedly installed on the top of the moving rod 11, and two stabilizing rings 21 are fixedly installed on the top of the mounting frame 5. The stabilizing rings 21 are slidably sleeved on the corresponding stabilizing rods 20. Through the sliding limiting cooperation between the stabilizing rods 20 and the stabilizing rings 21, the movement of the moving rod 11 can be stably supported.
[0042] As a preferred embodiment of this utility model, four fixing plates 16 are fixedly installed at the bottom of the mounting frame 5. A first guide roller 17 and a second guide roller 18 are rotatably connected between two corresponding fixing plates 16. The heat shrink film 15 is in contact with the first guide roller 17 and the second guide roller 18 respectively. By setting the cooperation between the fixing plates 16, the first guide roller 17 and the second guide roller 18, the heat shrink film 15 can be stably guided and transported.
[0043] It should be noted that the specific models of conveyor belt 2, first electric push rod 3, second electric push rod 6, thermoplastic plate 7, motor 9, and third electric push rod 19 used can be selected by those skilled in the art.

[0044] The working principle of this utility model is as follows: In use, firstly, the conveyor belt 2, the first electric push rod 3, the second electric push rod 6, the thermoplastic sheet 7, the motor 9, and the third electric push rod 19 are connected to an external power source. Then, the PE sheet is placed sequentially on top of the conveyor belt 2. Starting the conveyor belt 2 allows the PE sheet to be transported and moved below the shrink film assembly. At this time, starting the second electric push rod 6 moves the thermoplastic sheet 7 downwards, cooperating with the shrink film assembly to perform thermoplastic coating on the PE sheet. Starting the four first electric push rods 3 causes the two limiting strips 4 on both sides to move closer or further apart, thereby limiting the PE sheet and ensuring it is transported in the center of the conveyor belt 2, preventing deviation during transport and improving the quality of the thermoplastic coating process. Additionally, starting the motor 9 causes the two rectangular blocks 10 on it to rotate. By interlocking and limiting the rectangular block 10 with the corresponding rectangular sleeve 14, the rectangular sleeve 14 and the two rollers 13 can be rotated. The two rollers 13 rotate in opposite directions. The rear roller 13 is used to install the master roll of heat shrink film 15 and perform unwinding operation, while the front roller 13 is used to rewind the edge material of the used heat shrink film 15. In this way, the stable output and rewinding of heat shrink film 15 can be achieved, which can be used with thermoplastic board 7 to perform thermoplastic coating processing on multiple PE boards. By activating the third electric push rod 19, the moving rod 11 can be driven to move left and right. When the moving rod 11 moves to the left, it can drive the two rotating shafts 12 and the two rectangular blocks 10 on it to move to the left and release the interlocking and rotation support on the left end of the two rollers 13. At this time, it is easy to disassemble the two rollers 13 for easy disassembly and replacement.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
