This film can be a single layer or multi-layer structure with different performance characteristics to suit different types of food and packaging needs.

[0003] Food plastic film blow molding machine is a device used to produce plastic film for food packaging. Inside the blow molding machine, plastic particles are heated and melted. Usually, the plastic particles are heated by a heating cylinder or a heating element to make them into a plastic molten state. The molten plastic is extruded into a tubular shape.

The top of one group of slide plates 23 is fixedly connected with a fixing block 24. The fixing effect of the fixing block 24 prevents the fixing block 24 from falling off. The top of the other end slide plate 23 is fixedly connected to the bottom of the motor 5. The fixing effect of the motor 5 prevents the motor 5 from falling off. The output shaft of the motor 5 is fixedly connected with a sleeve 25. The sleeve 25 is symmetrically distributed in two groups. The other group of sleeves 25 is fixedly connected to the fixing block 24. The rotating effect of the sleeve 25 drives the rotating shaft 6 to rotate. The inner wall of the support frame 1 is fixedly connected with a fixing plate 26. The fixing plate 26 is an inclined plate, so that the winding roller 3 can slide to the back of the support frame 1 on the fixing plate 26. A limiting component 29 is provided on the inner wall of the right end of the rotating shaft 6. The limiting component 29 is used to limit the rotating shaft 6 so that the rotating shaft 6 remains fixed.

[0036] Reference Figure 4-Figure 6 The fixing assembly 4 includes a pressing plate 41, which is arc-shaped. A handle 42 is fixedly connected to the right side of the pressing plate 41. The inner wall of the handle 42 is elastically connected to a clamping block 43 through a spring 44. Through the elastic force of the spring 44, the clamping block 43 always maintains a clamping effect with the clamping groove 46 when not affected by external force, thereby limiting the handle 42. A fixing ring 45 is fixedly connected to the right side of the winding roller 3. A clamping groove 46 is provided on the outer wall of the fixing ring 45.

[0038] Reference Figure 3 and Figure 4 The limiting assembly 29 includes a wedge block 292, the bottom of which is elastically connected to the inner wall of the right end of the rotating shaft 6 through a limiting spring 293. Through the elastic force of the limiting spring 293, the wedge block 292 always maintains a clamping effect with the square groove 291 when not affected by external force, thereby limiting the rotating shaft 6. A square groove 291 is provided on the top of the sleeve 25.

[0039] Reference Figure 1 and Figure 2 The outer wall of the slide plate 23 is slidably connected to the inner wall of the top front end of the support frame 1. Through the sliding effect of the slide plate 23, the motor 5 or the fixed block 24 is driven to move laterally, so that the sleeve 25 can move laterally. The outer wall of the rotating shaft 6 is plugged into the inner wall of the sleeve 25. By plugging the rotating shaft 6 with the sleeve 25, the rotating shaft 6 can be installed on the sleeve 25. An electric push rod 22 is fixedly connected to the right side of the support frame 1. The electric push rod 22 is symmetrically distributed in two groups. The output end of the electric push rod 22 is fixedly connected to the outer wall of the slide plate 23. By starting the electric push rod 22, the slide plate 23 can be driven to slide.

[0040] Reference Figure 4 The outer wall of the pressure plate 41 is hinged to the inner wall of the winding roller 3. The pressure plate 41 can rotate through the hinge effect of the pressure plate 41. The outer wall of the handle 42 is rotatably connected to the inner wall of the fixing ring 45. The outer periphery of the handle 42 penetrates and is rotatably connected to the right inner wall of the winding roller 3. The rotation effect of the handle 42 drives the pressure plate 41 to rotate.

[0041] Reference Figure 5One end of the spring 44 is fixedly connected to the inner wall of the handle 42, and the other end of the spring 44 is fixedly connected to the outer wall of the block 43. The fixing effect of the spring 44 keeps the block 43 fixed to prevent the block 43 from falling off. The outer wall of the block 43 is slidably connected to the inner wall of the handle 42. The sliding effect of the block 43 allows the block 43 to be engaged or unengaged with the slot 46. The outer wall of the block 43 is engaged with the inner wall of the slot 46. The engagement effect of the block 43 and the slot 46 allows the fixing ring 45 to limit the handle 42.

[0042] Reference Figure 4 One end of the limit spring 293 is fixedly connected to the inner wall of the right end of the rotating shaft 6, and the other end of the limit spring 293 is fixedly connected to the bottom of the wedge block 292. The fixing effect of the limit spring 293 keeps the wedge block 292 fixed to prevent the wedge block 292 from falling off. The outer wall of the wedge block 292 is slidably connected to the inner wall of the right end of the rotating shaft 6. The sliding effect of the wedge block 292 allows the wedge block 292 to be engaged or released from the square groove 291. The outer wall of the wedge block 292 is engaged with the inner wall of the square groove 291. The engaging effect of the wedge block 292 and the square groove 291 allows the sleeve 25 to limit the rotating shaft 6.

[0043] Working principle: When the staff needs to roll up the plastic film, the staff plugs the right end of the rotating shaft 6 into the sleeve 25 fixed on the motor 5, and plugs the left end of the rotating shaft 6 into the sleeve 25 set on the fixed block 24. The staff presses the card block 43 to release the card connection effect with the card slot 46, and at the same time releases the limiting effect on the handle 42, and rotates the handle 42 backward, driving the pressure plate 41 to rotate upward and open.

[0044] The staff places one end of the plastic film to be rolled up on the inner wall of the winding roller 3 and rotates the handle 42 forward to make the pressure plate 41 rotate forward to press and fix one end of the plastic film. At the same time, the elastic force of the spring 44 causes the clamping block 43 to engage with the clamping groove 46, and the handle 42 is limited to keep the pressure plate 41 fixed. The motor 5 is started and the sleeve 25 is driven by the motor 5 to rotate. When the sleeve 25 rotates, the square groove 291 is driven to correspond to the wedge block 292, so that the wedge block 292 is engaged with the square groove 291 under the elastic force of the limiting spring 293. At the same time, the rotating shaft 6 is limited so that the sleeve 25 can drive the rotating shaft 6 to rotate, so that the winding roller 3 can roll up the plastic film.

[0045] When the winding is completed, the staff starts the hydraulic cylinder 27 to drive the arc plate 28 to move upward, so that the top of the arc plate 28 contacts the bottom of the rotating shaft 6, and the staff presses the wedge block 292 to release the clamping effect of the wedge block 292 on the square groove 291, and at the same time releases the limiting effect on the rotating shaft 6, and controls the electric push rod 22 to retract, so that the two groups of sleeves 25 move outward, and release the plug-in effect with the rotating shaft 6, and control the hydraulic cylinder 27 to descend, so that the arc plate 28 drives the rotating shaft 6 and the winding roller 3 to move downward. When the winding roller 3 contacts the top of the fixed plate 26, the arc plate 28 moves downward, and the supporting effect on the rotating shaft 6 is released, so that the rotating shaft 6 and the winding roller 3 slide along the fixed plate 26 to the back of the support frame 1 until they slide into the collection box 21 for collection and storage.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
