Description

Technical Field

[0001] The present invention relates to the technical field of hose production and processing, and in particular to an anti-clogging hose extruder. Background Art

[0002] Extruder is a type of plastic machinery, which originated in the 18th century. According to the direction of the material flow in the die and the angle between the center line of the screw, the die head of the extruder can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and the rare multi-screw extruders and screwless extruders.

[0003] At present, the use process of the hose extruder is to first pour the plastic particles into the extruder, and the screw in the extruder will transfer the plastic particles to the heater. The heater will melt the plastic particles and mix them evenly to make them into a flowing plastic liquid. The screw will transport the plastic liquid to the front of the die, and then extrude it to make it into a shape. However, since the plastic liquid is relatively viscous, it is easy to leave residues sticking to the die during extrusion. Over time, more and more residual sticky plastic will remain, and the die will be blocked. If the worker needs to clean the residual plastic on the die, he must suspend the extrusion work, disassemble the die, and then clean the residual plastic on the die. Such cleaning work is relatively cumbersome, consumes a lot of man-hours, and reduces the efficiency of hose extrusion.

[0004] Therefore, we are in urgent need of an anti-clogging hose extruder. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0031] An anti-clogging hose extruder, such as Figure 1-Figure 8 and Fig.10 As shown, it includes a base 1, a transmission mechanism 2, a stirring mechanism 3, a first heater 4 and a die replacement mechanism 5. The base 1 is a carrier. The right part of the base 1 is provided with a transmission mechanism 2, wherein the transmission mechanism 2 includes a first motor 21 and a screw rod 22. The right part of the base 1 is installed with the first motor 21, and the output shaft of the first motor 21 is connected with the screw rod 22 through a coupling. The base 1 is provided with a stirring mechanism 3, wherein the stirring mechanism 3 includes a barrel 31 and a feed pipe 32. The barrel 31 is welded on the base 1, and the screw rod 22 is located inside the barrel 31. The feed pipe 32 is connected to the barrel 31, and the inside of the feed pipe 32 rotates A valve is connected, a first heater 4 is installed at the center position of the base 1 by bolts, and the middle part of the cylinder 31 is wrapped by the first heater 4, and a die replacement mechanism 5 is provided on the left part of the cylinder 31, wherein the die replacement mechanism 5 includes a fixed frame 51, a pull rod 52, a first die 53 and a second die 54, a fixed frame 51 is passed through the left part of the cylinder 31, a pull rod 52 is slidably provided in the fixed frame 51 through a slide groove, the tail end of the pull rod 52 is connected to the first die 53 by bolts, and the rear end of the first die 53 is also connected to the second die 54 by bolts, and the upper and lower sides of the first die 53 and the second die 54 are connected to limiting blocks.

[0032] When the present invention is to be used, the valve is first unscrewed, and the plastic particles are poured into the cylinder 31 through the feed pipe 32. After the feeding is completed, the valve is tightened to prevent the heat loss in the cylinder 31, and the first motor 21 is started. The first motor 21 will drive the screw rod 22 to rotate, and the screw rod 22 will transport the plastic particles to the left. When the screw rod 22 transports the plastic particles to the first heater 4, the first heater 4 will heat and melt them. While melting, the screw rod 22 is also rotating and transporting, so as to mix the plastic liquids together. When the screw rod 22 transports the plastic liquid to the right side of the first die 53, the screw rod 22 will discharge the plastic liquid from the left end and discharge it from the first die 53. The material is extruded from the pores of the die 53, thereby extruding the rubber hose. When the first die 53 is blocked, the worker pulls the pull rod 52, and the pull rod 52 will move the first die 53 and the second die 54 forward. When the limit block of the second die 54 is fixed to the cylinder 31, the second die 54 will replace the first die 53 to discharge the material. The pull rod 52 is released, and the blocked first die 53 is cleaned. When the second die 54 is blocked, the pull rod 52 is pushed back to reset. Similarly, the cleaned first die 53 will replace the second die 54 to discharge the material, and then the blocked second die 54 can be cleaned. In this way, the cleaning work when the die of the present invention is blocked becomes simple and quick. Example 2

[0033] On the basis of Example 1, Figure 1 , Figure 5 and Figure 6 As shown, it also includes a prompt mechanism 6, a mounting frame 63 and a push plate 64, wherein the prompt mechanism 6 includes a mounting block 61 and a push rod 62, the mounting block 61 is welded to the left part of the cylinder 31, the middle part of the mounting block 61 is slidably provided with a push rod 62, the lower end of the push rod 62 is located inside the cylinder 31, the left part of the cylinder 31 is welded to the mounting frame 63, the mounting frame 63 is slidably provided with a push plate 64 through a slide groove, and the mounting frame 63 is located in front of the mounting block 61.

[0034] Since workers are not always at the device, when the die is blocked, the plastic liquid in the cylinder 31 will not be able to be discharged and will accumulate on the left side of the cylinder 31. At this time, the plastic liquid will push up the push rod 62 to remind the worker that the die is blocked and needs to be replaced and cleaned. When the push rod 62 is pushed up, a part of the plastic liquid will overflow from the gap between the mounting block 61 and the push rod 62. At this time, the push plate 64 is pushed to clear the overflowed plastic liquid. After clearing, the push rod 62 is reset. Example 3

[0035] On the basis of Example 2, Figure 1 , Figure 6 and Fig.10As shown, a cleaning mechanism 7 is also included, wherein the cleaning mechanism 7 includes a fixing rod 71, a mounting plate 72, an elastic member 73 and a brush plate 74. Two fixing rods 71 ​​are symmetrically connected to the fixing frame 51 front and back, and a mounting plate 72 is slidably provided between every two fixing rods 71. Elastic members 73 are connected between the upper ends of the fixing rods 71 ​​and the mounting plates 72 via spring seats. Brush plates 74 are installed on the mounting plates 72, and the brush plates 74 can be removed from the mounting plates 72.

[0036] like Figure 1 and Fig.10 As shown, it also includes an auxiliary cleaning mechanism 9, wherein the auxiliary cleaning mechanism 9 includes a first push rod 91, a first wedge rod 92, a second push rod 93 and a second wedge rod 94. The first push rod 91 is welded on the first die 53, and the front part of the front brush plate 74 is provided with a first wedge rod 92, the second push rod 93 is welded on the second die 54, and the rear part of the rear brush plate 74 is provided with a second wedge rod 94. The lower ends of the first push rod 91 and the second push rod 93 have cross-sections that perfectly match the first wedge rod 92 and the second wedge rod 94, and the first wedge rod 92 and the second wedge rod 94 can be removed from the brush plate 74.

[0037] When the pull rod 52 is pulled, when the lower end of the first push rod 91 contacts the first wedge rod 92, the lower end section of the first push rod 91 will move along the first wedge rod 92, and the first wedge rod 92 will move downward. When the first wedge rod 92 moves downward, it will bring the mounting plate 72 downward, and the mounting plate 72 will move downward with the brush plate 74. When the brush plate 74 moves downward, the brush will remove the plastic residue on the first die 53. When the mounting plate 72 is pressed downward, the elastic member 73 will be stretched. When the second die 54 is blocked, the pull rod 52 is pushed back to reset. At this time, the elastic member 73 When the second push rod 93 is in the process of rebounding, the elastic member 73 will bring the mounting plate 72 and the brush plate 74 back to their original positions, and the lower end section of the second push rod 93 will move along the second wedge rod 94. At this time, the second wedge rod 94 will move downward, and when the second wedge rod 94 moves downward, it will bring the mounting plate 72 downward, and the mounting plate 72 will move downward with the brush plate 74. When the brush plate 74 moves downward, the brush will remove the plastic residue on the second die 54. This allows the present invention to clean the die while replacing it. The brush plate 74 is detachable, which is convenient for replacing and cleaning the brush plate 74.

[0038] like Figure 1 , Figure 8 and Fig. 9As shown, a heating mechanism 8 is also included, wherein the heating mechanism 8 includes a second motor 81, a heating rod 82, a fixing block 83 and a second heater 84. The second motor 81 is installed on the left part of the base 1 by bolts, and the heating rod 82 is connected to the output shaft of the second motor 81 through a coupling. The left part of the base 1 is symmetrically connected to the fixing block 83, and the second heater 84 is installed on the fixing block 83. The left part of the cylinder 31 is wrapped by the second heater 84.

[0039] Start the second motor 81, the heating rod 82 will generate heat, and the heat generated by the heating rod 82 will be transferred to the second heater 84, and the second heater 84 will heat the left part of the barrel 31, thereby preventing the plastic liquid from cooling and condensing into blocks during the spiral rod 22 transporting the plastic liquid to the left part of the barrel 31, or during the extrusion process, thereby blocking the barrel 31 and making subsequent work difficult. After completing the extrusion work, the device is turned off.
