Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plastic sheet production equipment, and in particular to a heavy-duty calendering equipment. Background Art
[0002] The mold and calender are important components in the production line of sheet and film products. During the production process, after the mold is adjusted, the operator needs to move the calender to a position that matches the mold. Since the mold needs to enter a certain distance between the two rollers, the production process requires that the mold is as close to the tangent line of the roller pressing as possible. When moving, someone needs to watch the distance and adjust the moving distance. Since the heavy-duty three-roller machine moves slowly and has a width of 6-9 meters, the staff needs to observe carefully when the heavy-duty three-roller machine moves forward and backward to avoid the risk of collision with the mold when the heavy-duty three-roller machine is close to the mold, and to avoid derailment when it is far away from the mold. Summary of the invention

DETAILED DESCRIPTION
[0020] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.
[0021] The present application embodiment provides a heavy-duty calendering device, such as Figure 3 As shown, the heavy calendering device 100 is arranged at the front side of the extrusion die 200 and is opposite to the extrusion port of the extrusion die 200 .
[0022] like Figure 1 , 2 As shown, the heavy-duty calendering equipment 100 includes a movable guide rail 10 laid on the ground, a heavy-duty calender 20 capable of moving back and forth along the movable guide rail 10 , a driving device 30 for driving the heavy-duty calender 20 to move, and a pair of limiting devices 40 arranged on the movable guide rail 10 .
[0023] like Figure 3 As shown, the movable guide rail 10 extends in the front-to-back direction and at least partially extends to the bottom of the extrusion die 200. The movable guide rail 10 is made of I-beam.
[0024] like Figure 1 , 3 As shown, the heavy-duty calender 20 includes a frame 1, a plurality of calender rollers 2 rotatably arranged on the frame 1, and a movable gear train 3 arranged at the bottom of the frame 1. In the embodiment of the present application, the heavy-duty calender 20 is a three-roller calender. The heavy-duty calender 20 includes three calender rollers 2, and the three calender rollers 2 are sequentially arranged from top to bottom on the frame 1 for calendering the sheet extruded by the extrusion die 200.
[0025] like Figure 3-5 As shown, the moving wheel system 3 includes a plurality of moving wheels 31, and each moving wheel 31 is provided with an annular groove that cooperates with the moving guide rail 10 in the circumference. When the moving wheel 31 rolls on the moving guide rail 10, the upper part of the moving guide rail 10 is embedded in the annular groove. The cooperation between the annular groove and the moving guide rail 10 limits the movement of the moving wheel 31 in the left and right directions, so that when the moving wheel 31 moves back and forth along the moving guide rail 10, the moving wheel 31 is effectively prevented from deviating from the moving guide rail 10 during the rolling process.
[0026] The driving device 30 includes a moving motor 4 and a transmission belt 5. The transmission belt 5 extends in the front-to-back direction, and both ends of the transmission belt 5 are fixed on the ground. The moving motor 4 is connected to the transmission belt 5 in a transmission manner. When the moving motor 4 is working, it can move back and forth along the transmission belt 5. The moving motor 4 is fixedly connected to the frame 1. When the moving motor 4 is working, it drives the frame 1 and the three calender rollers 2 on the frame 1 to move in the front-to-back direction. The moving wheel train 3 cooperates with the moving guide rail 10 at the bottom of the frame 1. On the one hand, it reduces the friction between the heavy calender 20 and the moving guide rail 10, making it easier to move the heavy calender 20. On the other hand, it guides the movement of the heavy calender 20.
[0027] like Figure 2 , 5 As shown, a pair of limit devices 40 are relatively arranged on the movable guide rails 10 on both sides of the heavy-duty calender 20, each limit device 40 includes a limit block 6 that slides with the movable guide rail 10 and at least one locking bolt 7 that is threadedly connected to the limit block 6. At least one locking bolt 7 has a locking position and an unlocking position. In the locking position, the limit block 6 is fixed on the movable guide rail 10 and blocks the moving path of the movable wheel train 3; in the unlocking position, the limit block 6 can move back and forth along the movable guide rail 10.
[0028] Each limiting device 40 includes four locking bolts 7, and the four locking bolts 7 are connected to the limiting blocks 6 in pairs. Each locking bolt 7 can be pressed against the moving guide rail 10. When the four locking bolts 7 are tightened to press against the moving guide rail 10, the moving block 6 is fixed on the moving guide rail 10 and cannot move in the front and rear directions relative to the moving guide rail 10, thereby realizing the locking function.
[0029] The limit block 6 is a clamping ring limit block, and the cross section of the limit block 6 is "C" shaped. The two ends of the limit block 6 extend into the grooves of the I-beam, so that the limit block 6 can slide along the movable guide rail 10. A pair of limit devices 40 can be moved to the required limit position on the movable guide rail 10 in advance according to production requirements, and the limit block 6 is fixed at the required limit position by the locking bolt 7 to ensure the safety of the heavy calender 20 during movement.
[0030] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and the scope of protection required by the present application is defined by the attached claims, description and their equivalents.
