Description

Technical Field

[0001] The utility model relates to the field of film blowing machines, in particular to a support for film blowing machines which is easy to adjust. Background Art

[0002] The plastic film blowing machine heats and melts the plastic particles and then blows them into film. After the film is blown, the finished film needs to be rolled up. When rolling up, a winding bracket is needed to fix the support device for winding up to facilitate subsequent production and processing operations.

[0003] At present, most of the existing film winding supports are fixed supports, which makes it difficult to adjust the height. In addition, when winding, the film is hot, and it is inevitable that the film will stick together after being rolled into a circle, thus affecting the use. For this purpose, application number: CN202220925681.2 discloses a film winding support dedicated to a plastic film blowing machine, comprising a second support frame and a first support frame, wherein the second support frame is connected to the bottom end position of the first support frame. In the utility model, the height can be adjusted according to needs by adjusting the component structure, and the support thread column is rotated to pass through the second support frame, and then the first limit ring is used to be rotated and fastened to the upper end of the connection between the support thread column and the second support frame, and the second limit ring is rotated and fastened to the lower end of the connection between the support thread column and the second support frame. When adjusting the height, the first limit ring and the second limit ring are loosened to make the support thread column move up and down in the second support frame until it reaches a suitable height. Because one end of the support thread column is installed and connected to the fixed cross bar, it moves up and down accordingly, and then the first limit ring and the second limit ring are locked to prevent the support thread column from sliding down. When in use, the anti-slip rubber pad is used to make it more stable and less likely to slide during use.

[0004] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, a number of support studs are arranged between the frames, and the frame located above is limited by two limit rings threadedly connected on each support stud. When adjusting the height of the upper frame, the limit ring on each support stud needs to be adjusted in turn. The process is relatively cumbersome and the position of the limit ring cannot be accurately determined. This may cause the four corners of the upper frame to be at different heights, thereby reducing the support stability.

[0005] How to invent an easily adjustable film blowing machine bracket to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0006] In order to remedy the above deficiencies, the utility model provides an easily adjustable film blowing machine bracket, which aims to improve the existing technology by arranging a number of support studs between the frames, and then limiting the upper frame by two limit rings threadedly connected on each support stud. When adjusting the height of the upper frame, it is necessary to adjust the limit rings on each support stud in turn. The process is relatively cumbersome and the position of the limit ring cannot be accurately determined. This may cause the four corners of the upper frame to be at different heights, thereby reducing the support stability.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a film blowing machine support that is easy to adjust, including a film blowing machine winding roller mounting frame 1, the film blowing machine winding roller mounting frame 1 includes a connecting frame 101, both ends of the upper surface of the connecting frame 101 are integrally provided with support mounting frames 102, and a bottom ground contacting frame 3 is arranged parallel to the lower side of the connecting frame 101. The film blowing machine winding roller mounting frame 1 and the bottom ground contacting frame 3 are connected by a height adjustment support mechanism 2, and the height adjustment support mechanism 2 includes a group of first linkage rods 201 and a group of second linkage rods 202, and the number of each group of first linkage rods 201 and second linkage rods 202 is two, and the two groups of first linkage rods 201 and second linkage rods 202 are two. One end of the movable rod 202 is rotatably connected to the inner wall of the same side of the connecting frame 101 and the bottom ground contact frame 3, respectively. The other end of each group of first linkage rods 201 and second linkage rods 202 is rotatably connected to the corresponding sliding rod 203, respectively. The two sliding rods 203 are respectively located inside the connecting frame 101 and the bottom ground contact frame 3 and are arranged in parallel up and down, and both ends of each sliding rod 203 are slidably connected to the sliding grooves 204 opened on the inner walls on both sides of the corresponding connecting frame 101 or the bottom ground contact frame 3. The middle sections of the two first linkage rods 201 and the two second linkage rods 202 are rotatably connected to the hinge shaft 205, and the two second linkage rods 202 are connected to the driving device.

[0021] See also Figure 2 and Figure 3 The driving device is a hydraulic cylinder 207, one end of the hydraulic cylinder 207 is rotatably connected to the side surface of the first mounting rod 206, one end of the piston rod of the hydraulic cylinder 207 is rotatably connected to the side surface of the second mounting rod 208, the first mounting rod 206 is fixedly installed between the inner walls on both sides of the bottom ground contacting frame 3, and the second mounting rod 208 is fixedly installed between the opposite side surfaces of the two second linkage rods 202.

[0022] When the hydraulic cylinder 207 is started, its piston rod will drive the two second linkage rods 202 to rotate through the second mounting rod 208 when it is extended and retracted. When the second linkage rod 202 rotates at the end connected to the inner wall of the bottom ground-contacting frame 3, the other end will drive the corresponding sliding rod 203 to slide in the connecting frame 101 guided by the sliding groove 204, thereby lifting or pulling down the position of the connecting frame 101 and adjusting the height of the connecting frame 101. When the height of the connecting frame 101 changes, it will also drive one end of the two first linkage rods 201 to move, thereby changing the angle of the first linkage rod 201, so that the two sliding rods 203 can slide synchronously in the same direction, thereby improving the stability and convenience of the connecting frame 101 when the height is adjusted.

[0023] Furthermore, the four corners of the bottom surface of the connecting frame 101 are fixedly connected with limit slide bars 5, each limit slide bar 5 is slidably connected in the corresponding guide sleeve 6, and one end of the four guide sleeves 6 is fixedly connected to the four corners of the upper surface of the bottom ground contacting frame 3.

[0024] The connection frame 101 can be further limited by the sliding cooperation of the limiting slide rod 5 and the guide sleeve 6, so that it cannot tilt and can only be lifted up and down, thereby further improving the stability of the connection frame 101 during lifting and use.

[0025] See also Figure 4 A cooling assembly 4 is also provided on one side of the connecting frame 101, and the cooling assembly 4 includes a cold air box 401, and a plurality of cold air pipe interfaces 402 connected to the interior of the cold air box 401 are integrally provided on the surface of one side of the cold air box 401, and an air outlet mesh plate is provided on the surface of the other side of the cold air box 401, and a plurality of extension portions 403 are integrally provided on the bottom surface of the cold air box 401, each extension portion 403 is located in a corresponding accommodating groove 404, and a plurality of accommodating grooves 404 are opened on the surface of one side of the connecting frame 101, and a rotating shaft 405 is rotatably installed between the inner walls at both ends of each accommodating groove 404, and one end of each extension portion 403 is fixedly connected to the outer wall of the corresponding rotating shaft 405, and a worm gear 406 is fixedly sleeved on one of the rotating shafts 405, and the worm gear 406 is meshedly connected with a worm 407 on one side, and one end of the worm 407 is rotatably installed on the surface of one side of a mounting plate 408, and the mounting plate 408 is fixedly connected to the surface of one side of the connecting frame 101.

[0026] The external cold air output device is connected to the cold air box 401 through the cold air pipe interface 402. After the cold air enters the cold air box 401, it is discharged from the air outlet mesh plate on the other side to act on the film to reduce its temperature to avoid adhesion caused by high temperature during the winding process. At the same time, when the height adjustment support mechanism 2 adjusts the overall height of the film blowing machine winding roller mounting frame 1, the angle of the film output and winding by the film blowing machine will also change accordingly during the winding roller process. In order to ensure the cooling efficiency of the film and make the cold air fully contact the film surface, the worm gear 406 can be driven to rotate by rotating the worm 407. Because the mounting plate 408 is fixedly mounted on one of the rotating shafts 405, and the rotating shaft 405 is fixedly connected to the cold air box 401 through the extension part 403, the rotation of the worm gear 406 can drive the cold air box 401 to adjust its angle as a whole, thereby avoiding the change of the film output and winding angle after adjusting the height of the film blowing machine winding roller mounting frame 1, and the cold air cannot fully contact the film surface, resulting in a decrease in cooling efficiency.

[0027] Furthermore, a support rod is fixedly connected between the support mounting frame 102 and the connecting frame 101 .

[0028] The support rod (not marked in the figure) plays a supporting role between the connecting frame 101 and the supporting mounting frame 102, thereby ensuring the overall structural strength of the film blowing machine winding roller mounting frame 1 and avoiding the overall deformation of the film blowing machine winding roller mounting frame 1 due to the increase in the weight of the wound film.

[0029] Working principle: First, connect the winding roller to the supporting mounting frame 102. When the film blowing machine is working, the output film is wound on the winding roller. The hydraulic cylinder 207 can be started according to actual usage and needs to drive the second linkage rod 202 and the first linkage rod 201 to rotate synchronously, thereby improving the convenience and stability when adjusting the height of the winding roller mounting frame 1 of the film blowing machine. At the same time, when the overall height of the winding roller mounting frame 1 of the film blowing machine changes, the angle of film output and winding also changes. At this time, the angle of the cold air box 401 can be adjusted by rotating the worm 407, and then cold air is delivered to the inside of the cold air box 401 through the external cold air output device. The cold air is evenly output by the air outlet mesh plate arranged on one side of the cold air box 401 to fully act on the surface of the film to cool it down, thereby avoiding adhesion during the winding process.

[0030] It should be noted that the specific model and specifications of the hydraulic cylinder 207 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0031] The power supply and principle of the hydraulic cylinder 207 are clear to those skilled in the art and will not be described in detail here.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
