Description

Technical Field

[0001] This utility model relates to the technical field of plastic film production equipment, specifically a guiding device for blown film machine products. Background Technology

[0002] As the demand for plastic bags in people's lives increases, blown film extrusion machines for manufacturing plastic films have emerged. The raw material for plastic film production is plastic granules. Under the action of a feeder, the plastic granules are sucked into a screw extruder through a feed pipe connected to the feeder. The screw extruder conveys the plastic granules, which are then heated and extruded from the die. The plastic bag product extruded from the die is cooled by air blowing through a blower pipe and continues to be conveyed upwards. After being extruded at the highest point of the blown film extrusion machine, it is conveyed and wound up. Because the plastic bag product extruded from the die is cylindrical, the overall length of the extruded plastic bag product is very long before it is cut.

[0003] For example, Chinese patent CN215619945U discloses a conveying mechanism for a blown film machine. A support frame is disposed above the blown film machine body, and several sets of limiting components are provided on the support frame. These limiting components are evenly arranged along the circumference of the support frame. Each limiting component includes a limiting rod, which is movably connected to the support frame and is horizontally positioned. The limiting rod is used to abut against the outer wall of the plastic film product. This application has the effect of improving the stability of upward conveying of plastic bag products.

[0004] However, in practical applications, when adjusting the limit rods in the existing conveying mechanism, each connecting rod needs to be rotated separately using each handle, thereby driving multiple limit rods on each connecting rod to rotate and adjust. The adjustment steps are cumbersome, and rotating each connecting rod separately cannot guarantee that the limit rods on each connecting rod simultaneously contact the outer wall of the plastic film product, which will affect the limiting and guiding effect on the plastic film product. Utility Model Content

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Example 1

[0024] Please refer to Figures 1 to 5 As shown, a guiding device for blown film products includes a support frame 1 with a through hole at the top for the plastic film product to pass through. A blown film machine is mounted at the bottom of the support frame 1, and a die head 2 is mounted at the top of the blown film machine. The die head 2 has a circular opening facing upwards. A lower fixing ring 3 is connected to the top of the support frame 1, and several support rods 4 arranged in a circular array are fixedly connected to the top of the lower fixing ring 3. An upper fixing ring 5 is fixedly connected to the top of each support rod 4. The axes of the die head 2, the through hole, the lower fixing ring 3, and the upper fixing ring 5 all coincide. Each support rod 4 is rotatably connected to a rotating plate 6. A connecting plate 7 is integrally formed on the outer side of the rotating plate 6. A slot 8 is opened on the connecting plate 7. A connecting rod 9 is rotatably connected in two adjacent slots 8. A drive mechanism 10 connected to one of the connecting plates 7 is provided on the top of the upper fixing ring 5. Several connectors 11 are slidably arranged on the inner side of the rotating plate 6. A locking component 12 is provided on the connector 11. Several adjusting grooves 13 that cooperate with the locking component 12 are opened on one side of the rotating plate 6. A limit guide rod 14 is connected to one side of the connector 11.

[0025] As will be understood by those skilled in the art, when the present invention limits and guides the plastic film product, the drive mechanism 10 drives one of the connecting plates 7 and the rotating plate 6 to rotate. With the cooperation of several connecting rods 9, each rotating plate 6 will rotate synchronously, thereby driving each limiting guide rod 14 to rotate synchronously, so that each limiting guide rod 14 can simultaneously adhere to the outer wall of the plastic film product, thereby guiding and limiting the plastic film product. The operation process is simple and convenient, and at the same time, it can quickly make each limiting guide rod adhere to the outer wall of the plastic film product, ensuring the stability of the plastic bag product being conveyed upward.

[0026] In addition, the connector 11 is slidably connected to the rotating plate 6, which facilitates the sliding adjustment of the height of each connector 11 and the limiting guide rod 14 according to actual needs. The locking component 12 and the adjustment groove 13 can quickly limit and fix the adjusted connector 11 and the limiting guide rod 14, thereby enhancing the practicality of the device and further meeting the work requirements. There are eight rotating plates 6 in this device, and each rotating plate 6 is provided with three limiting guide rods 14, for a total of twenty-four limiting guide rods 14. The limiting guide rods 14 on each rotating plate 6 are staggered with the limiting guide rods 14 on adjacent rotating plates 6, so that rotation will not affect the rotation of the limiting guide rods 14 on adjacent rotating plates 6.

[0027] Example 2

[0028] Furthermore, the outer ring of the lower fixing ring 3 is fixedly connected to several mounting plates 15 arranged in a ring array. The mounting plates 15 have mounting holes 16 extending vertically through them. Mounting bolts 17 are inserted into the mounting holes 16, and the bottom end of the mounting bolts 17 is threaded into the support frame 1.

[0029] Those skilled in the art will understand that by providing the mounting plate 15, mounting holes 16, and mounting bolts 17, the lower fixing ring 3 and the support frame 1 are detachably connected, making it convenient to remove and replace the entire structure of the lower fixing ring 3 for repair when the structural components on the lower fixing ring 3 are damaged.

[0030] Example 3

[0031] Furthermore, a T-shaped groove 18 is provided on the inner side of the rotating plate 6, and a T-shaped slider 19 that matches the T-shaped groove 18 is fixedly connected to the side of the connector 11 near the rotating plate 6. Each connector 11 is slidably connected to the rotating plate 6 through the cooperation of the T-shaped groove 18 and the T-shaped slider 19.

[0032] As will be understood by those skilled in the art, when adjusting the height of the connector 11, the connector 11 drives the T-shaped slider 19 to move up and down in the T-shaped groove 18, thereby adjusting the height of the connector 11 and realizing the adjustment of the height position of the limiting guide rod 14. This makes it convenient to adjust each limiting guide rod 14 to a suitable height according to actual needs to meet the work requirements.

[0033] Example 4

[0034] Furthermore, a threaded connection groove 20 is provided on the side of the connector 11 away from the rotating plate 6, and a threaded connection rod 21 that is adapted to the threaded connection groove 20 is integrally formed on one end of the limiting guide rod 14. The limiting guide rod 14 is detachably connected to the connector 11 through the cooperation of the threaded connection groove 20 and the threaded connection rod 21.

[0035] Those skilled in the art will understand that the detachable limit guide rod 14 in this utility model is convenient for operators to replace. When replacing, simply turn the threaded connecting rod 21 through the limit guide rod 14 to disengage it from the threaded connecting groove 20, and the limit guide rod 14 can be removed. The operation is simple and convenient.

[0036] In addition, there are twenty-four limiting guide rods 14 in this device, but not all of them need to be installed and used. An appropriate number of limiting guide rods 14 can be installed according to actual needs, but it is necessary to ensure that at least one limiting guide rod 14 is installed on each rotating plate 6 to ensure the most basic guiding and limiting of the plastic film product.

[0037] Example 5

[0038] Furthermore, the drive mechanism 10 includes a first rotating block 1001 rotatably connected to the top of the upper fixed ring 5. An electric telescopic rod 1003 is fixedly connected to one side of the first rotating block 1001. A second rotating block 1002 is fixedly connected to the output end of the electric telescopic rod 1003. The second rotating block 1002 is rotatably connected to the top of one of the connecting plates 7 via a rotating rod.

[0039] Those skilled in the art will understand that when the drive mechanism 10 of this utility model is in use, it activates the electric telescopic rod 1003, causing the telescopic rod of the electric telescopic rod 1003 to extend or retract, and through the cooperation of the first rotating block 1001 and the second rotating block 1002, it drives one of the connecting plates 7 and the rotating plate 6 to rotate.

[0040] In addition, the electric telescopic rod 1003 used in this device is existing technology, and its working principle and power source are also existing technology, so it will not be elaborated on here.

[0041] Example 6

[0042] Furthermore, the locking assembly 12 includes a bracket 1201 fixedly connected to one side of the connector 11. A rod 1202 adapted to the adjustment groove 13 is movably inserted into the bracket 1201. A pull block 1203 is fixedly connected to the end of the rod 1202 away from the adjustment groove 13. A spring 1204 sleeved on the outside of the rod 1202 is fixedly connected between the pull block 1203 and the bracket 1201.

[0043] As will be understood by those skilled in the art, when using the locking component 12 of this utility model, the plug rod 1202 is first pulled by the pull block 1203, so that one end of the plug rod 1202 is disengaged from the adjustment groove 13. At this time, the spring 1204 has been stretched. Then, the connector 11 is slid to a suitable height and aligned with the adjustment groove 13 at a similar position. Finally, the pull block 1203 is released, and the spring 1204 will return to its original state, while driving the plug rod 1202 to be inserted into the adjustment groove 13, thereby limiting and fixing the connector 11.

[0044] In addition, when the spring 1204 is stretched to its maximum value, the insertion rod 1202 will just disengage from the adjustment groove 13, but will not disengage from the bracket 1201, thus preventing the insertion rod 1202 from falling off the bracket 1201 and affecting subsequent use.

[0045] The working principle and usage procedure of this device are as follows: When using this device, first install an appropriate number of guide and limiting rods 14 according to actual needs, then adjust each limiting guide rod 14 to a suitable height, and finally start the electric telescopic rod 1003 to extend or retract the telescopic rod of the electric telescopic rod 1003. Through the cooperation of the first rotating block 1001 and the second rotating block 1002, one of the connecting plates 7 and the rotating plate 6 will rotate. With the cooperation of several connecting rods 9, each rotating plate 6 will rotate synchronously, thereby driving each limiting guide rod 14 to rotate synchronously, so that each limiting guide rod 14 can simultaneously adhere to the outer wall of the plastic film product, thereby guiding and limiting the plastic film product.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
