Description

Technical Field

[0001] This invention relates to the field of molding machine technology, specifically a spiral high-pressure plastic extrusion molding machine. Background Technology

[0002] The spiral high-pressure plastic extrusion molding machine is a type of machine that collects mulch film and brings it to the factory, where the factory shreds, cleans, washes, squeezes it dry, and shapes it into recyclable plastic granules.

[0003] Existing technologies make it difficult to actively and forcibly separate and expel the air mixed between fibers in advance during use. This makes it difficult to fundamentally solve the "air resistance" effect caused by the compression of expandable air in subsequent screw extruders, increasing the energy consumption of the main unit and making it difficult for the screw to improve the overall dewatering efficiency and output stability, thus reducing the quality of recycled pellets. Existing technologies also make it difficult to generate strong friction through speed difference to forcibly peel off and separate impurities such as mud and sand attached to the surface of the mulch film. This makes it difficult to achieve a deep cleaning effect far exceeding that of conventional crushers. Furthermore, it is difficult to synchronously control the operation of the filling parts when some equipment is in differential motion, resulting in limited practicality. Finally: When the material enters the screw of the extruder, it is still in a loose state. Under the agitation of the screw, air is easily incorporated again. Existing technology makes it difficult to compress the loose material into an extremely dense block plug in the cylinder, completely eliminating the secondary air incorporated during the material conveying process, thus reducing the extrusion efficiency. When encountering hard foreign objects, existing technology makes it difficult to reduce rigidity to "flexibly avoid" them. When handling high-viscosity materials, existing technology makes it difficult to increase rigidity to ensure conveying force and stability. Therefore, it is difficult to realize the transition of the screw from passively bearing the load to actively adapting to the working conditions, which reduces the equipment's ability to handle complex materials, operational reliability, and energy efficiency.

The embodiments of this invention will now be described according to its overall structure.

[0021] Example 1:

[0022] Please see Figures 1-4 The present invention provides a spiral high-pressure plastic extrusion molding machine, comprising a spiral extrusion molding machine body 1, a molding mold box 2 located on the lower left side of the spiral extrusion molding machine body 1, a feed inlet 3 fixedly connected to the top right end of the spiral extrusion molding machine body 1, an adjustment mechanism 4 fixedly connected to the top of the feed inlet 3, an extrusion mechanism 5 fixedly connected to the lower right end of the adjustment mechanism 4, and a filling mechanism 6 fixedly connected to the left end of the spiral extrusion molding machine body 1.

[0023] The adjustment mechanism 4 includes a first mounting box 41. The first mounting box 41 is fixedly connected to the top of the feed inlet 3. The mounting frame 42 is fixedly connected to the top front end of the first mounting box 41. The first motor 43 is fixedly connected to the right front end of the mounting frame 42. The mounting frame 42 facilitates the installation and fixing of the first motor 43.

[0024] A screw 44 is fixedly connected to the output shaft at the left end of the first motor 43. A first moving block 45 is threadedly connected to the outer wall of the screw 44. A first sliding plate 46 is fixedly connected to the back of the first moving block 45. The outer wall of the first sliding plate 46 is slidably connected to the center of the top right end of the mounting bracket 42. The screw 44 facilitates the movement of the first moving block 45.

[0025] A second sliding plate 47 is slidably connected to the center of the top left end of the mounting bracket 42. The bottom of the second sliding plate 47 is rotatably connected to the top left end of the connecting rod 48. A first gear set 49 is rotatably connected to the bottom of the connecting rod 48. A differential mechanism 410 is fixedly connected to the back of both the first sliding plate 46 and the second sliding plate 47. There are two sets of connecting rods 48, and the two sets of connecting rods 48 are located on the upper and lower sides of the first gear set 49. The center of the connecting rod 48 is rotatably connected to the mounting bracket 42.

[0026] An electric spring 411 is fixedly connected between the first sliding plate 46 and the second sliding plate 47, and the electric spring 411 is electrically connected to an external power supply device. Resistance strain gauges 412 are attached to each of the spring wire axes of the electric spring 411 in the ±45° direction. The outer wall of the first moving block 45 is slidably connected to the top right front end of the mounting bracket 42, and the bottom of the first sliding plate 46 is rotatably connected to the top right end of the connecting rod 48.

[0027] The working principle of a spiral high-pressure plastic extrusion molding machine based on Embodiment 1 is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Second, the staff will collect the plastic film back to the factory, and then use external equipment to shred, clean and wash the plastic film. Then, the plastic film will be squeezed and melted by the screw extrusion molding machine body 1. The screw extrusion molding machine body 1 will transport the squeezed and melted plastic film to the molding mold box 2. The mold in the molding mold box 2 will form plastic granules from the squeezed and melted plastic film. Third, after the external equipment tears, cleans, and washes the mulch film, it is transported into the first installation box 41. The first motor 43 is started, driving the screw 44 to rotate. The screw 44 drives the first moving block 45 to move left or right. The first moving block 45 drives the first sliding plate 46 to move left or right. The first sliding plate 46 drives the connecting rod 48 to rotate. The connecting rod 48 drives the first gear set 49 to mesh and gradually gather or disperse. Through the cooperation of the connecting rod 48 and the first gear set 49, the second sliding plate 47 is driven to move right or left. The movement of the first sliding plate 46 to the left or right and the second sliding plate 47 to the right or left causes the distance between the two sets of differential mechanisms 410 to gradually shorten or increase. The two sets of differential mechanisms 410 drive the distance between the two sets of pressure rollers 4102 to gradually shorten or increase, realizing the adjustment of the distance between the two sets of pressure rollers 4102. The two sets of pressure rollers 4102 squeeze the mulch film, thereby expelling the air mixed between the fibers. The forced separation and discharge of air in advance fundamentally solves the "air resistance" effect caused by the compression of expandable air in the main body 1 of the subsequent spiral extrusion molding machine, reduces the energy consumption of the main machine, improves the overall dewatering efficiency and output stability, and improves the quality of recycled granules. During the movement of the first sliding plate 46 and the second sliding plate 47, the electric spring 411 is driven by the external power supply. The first sliding plate 46 and the second sliding plate 47 drive the electric spring 411 to perform extension or contraction movements, so that the electric spring 411 generates a stress field around it. This stress field affects the resistance value of the resistance strain gauge 412. Then, the resistance strain element inside the resistance strain gauge 412 is deformed under the action of stress. The operator can calculate the length change of the electric spring 411 by the resistance value of the resistance strain gauge 412. The distance between the two sets of pressure rollers 4102 is obtained by detecting the movement distance of the first sliding plate 46 and the second sliding plate 47 through the length change of the electric spring 411.

[0028] Example 2:

[0029] Please see Figure 2 and Figure 5The present invention provides a spiral high-pressure plastic extrusion molding machine. Compared with Embodiment 1, this embodiment further includes: a differential mechanism 410. The differential mechanism 410 includes a mounting shell 4101. The back of the first sliding plate 46 and the second sliding plate 47 are both fixedly connected to the mounting shell 4101. The back of the mounting shell 4101 is rotatably connected to a pressure roller 4102. A special toothed sleeve 4103 is sleeved on the outer wall of the pressure roller 4102. The pressure roller 4102 facilitates the installation of the special toothed sleeve 4103.

[0030] A first connecting seat 4104 is fixedly connected to the center of the bottom inside the mounting housing 4101. A dual-axis motor 4105 is fixedly connected to the front left end of the first connecting seat 4104. Connecting rods 4106 are fixedly connected to the output shafts at both ends of the dual-axis motor 4105. The connecting rods 4106 are segmented and consist of two sets of rods that are sleeved together. The front and rear rods of the connecting rods 4106 are respectively inserted and fixed to the front and rear slots of the electromagnetic clutch 4107. The dual-axis motor 4105 can easily drive the connecting rods 4106 to rotate.

[0031] The front end of the connecting rod 4106 of the dual-axis motor 4105 is fixedly connected to the gear inside the gear plate 4108. A control switch 4109 is fixedly connected to the top front end inside the mounting housing 4101. A second gear set 41010 is fixedly connected to the back of the connecting rod 4106 of the dual-axis motor 4105. The control switch 4109 facilitates driving the third motor 63 to work.

[0032] The back of the right gear of the second gear set 41010 contacts the friction block 41011 via a gear rod. The bottom of the friction block 41011 is detachably connected to a second connecting seat 41012, and the bottom of the second connecting seat 41012 is fixedly connected to the rear end of the bottom of the mounting shell 4101. The gear inside the gear tooth plate 4108 is rotatably connected to the front end of the mounting shell 4101. The second connecting seat 41012 facilitates the installation of the friction block 41011.

[0033] The inner gear plate of gear tooth plate 4108 is slidably connected to the front end of the mounting shell 4101. The control switch 4109 is electrically connected to the third motor 63. The front end of the second gear set 41010 is rotatably connected to the back of the first connecting seat 4104. The back of the gear rod at the right end of the second gear set 41010 is fixedly connected to the back of the gear rod. The pressure roller 4102 is fixedly connected to the back of the gear rod.

[0034] In this embodiment: First, workers attach friction blocks 41011 with different friction coefficients to the outer wall of the gear rods inside the two sets of second gear sets 41010. They then start the two sets of dual-shaft motors 4105 and their rear electromagnetic clutches 4107, causing the electromagnetic clutches 4107 to lock the connecting rods 4106 on the back of the dual-shaft motors 4105. This causes the two sets of dual-shaft motors 4105 to drive their rear connecting rods 4106 to rotate. The two connecting rods 4106 then drive the two sets of second gear sets 41010 to rotate, which in turn drive their rear gear rods to rotate. Through the contact between the rear gear rods of the two sets of second gear sets 41010 and the friction blocks 41011 with different friction coefficients, differential rotation is formed. This causes the two sets of pressure rollers 4102 to rotate differentially, and the two sets of pressure rollers 4102 to rotate differentially. As the mulch film passes through, it is not only torn apart, but also generates huge shearing and kneading forces through the speed difference, forcibly separating the mulch film from the soil and impurities. Second, when it is necessary to control the third motor 63 to work, the dual-shaft motor 4105 and its front electromagnetic clutch 4107 are started, so that the electromagnetic clutch 4107 locks the front connecting rod 4106 of the dual-shaft motor 4105, thereby causing the dual-shaft motor 4105 to drive its front connecting rod 4106 to rotate. The connecting rod 4106 drives the internal gear of the gear plate 4108 to rotate. The internal gear of the gear plate 4108 drives the internal gear plate of the gear plate 4108 to move upward, so that the internal gear plate of the gear plate 4108 presses against the control switch 4109, thereby driving the third motor 63 to work through the control switch 4109.

[0035] Example 3:

[0036] Please see Figure 6 The present invention provides a spiral high-pressure plastic extrusion molding machine. Compared with the first embodiment, this embodiment further includes an extrusion mechanism 5. The extrusion mechanism 5 includes a second mounting box 51.

The top output shaft of the second motor 52 is fixedly connected to a turntable 53. The second motor 52 facilitates driving the turntable 53 to rotate.

[0037] The top rear end of the turntable 53 is rotatably connected to a first rotating rod 54, and the top left end of the first rotating rod 54 is rotatably connected to a first swing rod 55. The front and rear ends of the top of the first swing rod 55 are rotatably connected to second swing rods 56. The first rotating rod 54 facilitates the swinging of the first swing rod 55.

[0038] The left side of the second swing rod 56 is rotatably connected to the right end of the second moving block 57.

The bottom of the limiting cylinder 58 is fixedly connected to the bottom of the second mounting box 51. The left end of the pressing cylinder 511 is fixedly connected to the left end of the first mounting box 41.

[0040] In this embodiment: After the two sets of pressure rollers 4102 squeeze the plastic film, the film falls into the extrusion cylinder 511. Then, the second motor 52 is started, which drives the turntable 53 to rotate. The turntable 53 drives the first rotating rod 54 to swing. The first rotating rod 54 drives the first swing rod 55 to swing to the left rear end. The first swing rod 55 drives the second swing rod 56 at its top rear end to swing to the left. The second swing rod 56 drives the second moving block 57 to move to the left within the limiting cylinder 58. The second moving block 57 drives the extrusion block 510 to move to the left, so that the extrusion block 510 squeezes the plastic film in the extrusion cylinder 511 and compresses it into an extremely dense block material. The material is then conveyed through the bottom output slot of the extrusion cylinder 511 to the feed inlet 3, and then through the feed inlet 3 to the spiral extrusion molding machine body 1, completely eliminating secondary air entrapment during the material conveying process and improving extrusion efficiency. When the first swing rod 55 drives the second swing rod 56 at its top rear end to swing to the right, the second swing rod 56 at the top front end of the first swing rod 55 swings to the left. The second swing rod 56 drives the second moving block 57 to move to the left within the limiting cylinder 58, so that the second moving block 57 squeezes the counter 59. The counter 59 transmits the data information to the external display screen to determine the number of times the mulch film is conveyed.

The limit block 612 facilitates the limited movement of the piston rod in the piston cylinder 615.

[0045] The rear end of the outer wall of the second rotating rod 613 is rotatably connected to the second fixed seat 614. The back of the second fixed seat 614 is fixedly connected to the piston rod inside the piston cylinder 615. The top and rear ends of the piston cylinder 615 are fixedly connected to connecting pipes 616. A one-way valve 617 is fixedly connected to the conveying port of the connecting pipe 616. The right end of the connecting pipe 616 at the rear end of the piston cylinder 615 is rotatably connected to the screw inside the spiral extrusion molding machine body 1. The screw inside the spiral extrusion molding machine body 1 has a hollow structure.

[0046] The transmission component 69 consists of a micro motor fixedly connected to the top of the slide plate 68, a micro screw fixedly connected to the bottom output shaft of the micro motor, and a micro moving block threadedly connected to the outer wall of the micro screw. The left end of the micro moving block is rotatably connected to a second rotating rod 613. The bottom of the mounting plate 611 is fixedly connected to the bottom of the third mounting box 61. The piston rod inside the piston cylinder 615 passes through the limiting block 612 and is slidably connected to its interior.

[0047] In this embodiment: First, a magnetorheological fluid is filled inside the core shaft of the screw inside the screw body 1 of the screw extrusion molding machine, and it is electrically connected to an external adjustable magnetic field generator. By changing the magnetic field strength, the viscosity of the magnetorheological fluid is changed. That is, when the viscosity of the magnetorheological fluid is low, the damping force on the screw inside the screw body 1 during operation is small, and the rigidity of the screw inside the screw body 1 is relatively low. When the viscosity of the magnetorheological fluid is high, the damping force on the screw inside the screw body 1 increases, and its rigidity will also increase accordingly. This realizes the adjustment of the rigidity of the screw inside the screw body 1, enabling the screw inside the screw body 1 to transition from passively bearing the load to actively adapting to the working conditions, thereby improving the equipment's ability to process complex materials, operational reliability, and energy efficiency. Second, when it is necessary to fill the magnetorheological fluid, the micro motor inside the transmission component 69 and the two sets of one-way valves 617 are activated, and the magnetorheological fluid is delivered into the piston cylinder 615 through the connecting pipe 616 at the top of the piston cylinder 615. Then, the micro motor inside the transmission component 69 drives the micro screw inside the transmission component 69 to rotate, and the micro screw inside the transmission component 69 drives the micro moving block inside the transmission component 69 to move up or down. The filling amount of the magnetorheological fluid is adjusted by the movement position of the micro moving block inside the transmission component 69. Then, the third motor 63 is activated, and the third motor 63 drives the rotating block 64 to rotate. The rotating block 64 drives the sliding block 65 to make a circular motion and drives the swing frame 66 to swing. The swing frame 66 drives the fixed rod 67 to rotate. The fixed rod 67 drives the slide plate 68 to swing. The slide plate 68 drives the second rotating rod 613 to swing through the micro moving block in the transmission component 69. The second rotating rod 613 drives the piston rod in the piston cylinder 615 to move backward through the rotational connection with the second fixed seat 614. This allows the magnetorheological fluid in the piston cylinder 615 to be transported to the screw in the screw extrusion molding machine body 1 through its back connecting pipe 616, thereby realizing the filling of the magnetorheological fluid.

[0048] This invention provides an improved spiral high-pressure plastic extrusion molding machine. An adjustment mechanism 4 is incorporated to adjust the distance between two sets of pressure rollers 4102. These rollers then compress the plastic film, actively and forcibly separating and expelling the air mixed between the fibers. This fundamentally solves the "air resistance" effect caused by compressing expandable air in the main body 1 of the spiral extrusion molding machine, reducing the main machine's energy consumption, improving overall dewatering efficiency and output stability, and enhancing the quality of recycled pellets. A differential speed mechanism 410 is also included. Through the differential rotation of the two sets of pressure rollers 4102 and two sets of special toothed sleeves 4103, the plastic film is not only torn apart as it passes through, but the speed difference also generates enormous shearing and kneading forces, separating the plastic film from the mud. Soil and impurities are forcibly separated, and the control switch 4109 is squeezed by the inner tooth plate of the gear tooth plate 4108 to control the third motor 63 to work, improving practicality; a squeezing mechanism 5 is set up to squeeze the mulch in the squeezing cylinder 511 through the squeezing block 510 and press it into an extremely dense block plug, completely eliminating secondary air entrainment during the material conveying process, improving squeezing efficiency, and then the number of times the mulch is conveyed is determined by the counter 59; a filling mechanism 6 is set up to rigidly adjust the screw inside the spiral extrusion molding machine body 1, so that the screw inside the spiral extrusion molding machine body 1 can transition from passively bearing the load to actively adapting to the working conditions, improving the equipment's ability to handle complex materials, operational reliability and energy efficiency.
