Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of plastic film technology, and more specifically, to a PE film stretch wrapping machine. Background Technology

[0002] PE film, or polyethylene film, refers to film produced from PE granules. PE stretch film has high tensile strength, tear resistance, transparency, and good shrinkage force, with a pre-stretch ratio of 400%. It can be used for containerization, waterproofing, dustproofing, spill prevention, and theft prevention. Applications: Used for pallet wrapping and other stretch packaging, widely used in foreign trade exports, bottle and can manufacturing, papermaking, hardware and electrical appliances, plastics, chemicals, building materials, agricultural products, food, and other industries. Stretch film machines are used to assist in wrapping the PE film during packaging. Stretch film machines, also known as pallet packing machines or stretch film wrapping machines, are specialized equipment for bulk cargo packaging and belong to the category of intelligent packaging machinery. They improve efficiency through mechanized wrapping and are used in logistics, airport baggage packaging, and papermaking, chemical, and other fields.

[0003] Existing stretch wrapping machines place goods on a pallet, and the goods rotate as the pallet rotates. At the same time, PE film is used to wrap the surface of the goods. However, after wrapping, the broken parts of the PE film tend to stick together, making it difficult for the beginning of the wrapping to adhere to the surface of the goods.

[0004] The aforementioned stretch wrapping machine suffers from a problem where the PE film tends to stick together at the break point, making it difficult for the initial section of PE film to adhere to the surface of the goods, thus reducing the effectiveness of the device. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a PE film stretch wrapping machine to solve the technical problem in the prior art where the PE film is prone to sticking at the break point, making it difficult for the PE film initially wrapped by the operator to adhere to the surface of the goods.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a PE film stretch wrapping machine, which includes a first connecting frame, and further includes an adjusting block, adjusting pin, adjusting frame, adjusting column, guide frame, guide roller, push rod motor, fixing plate, fixing column, fixing frame, fixing ball, pushing mechanism and dividing mechanism;

[0007] The adjusting block is slidably connected within the first connecting frame. An adjusting pin is threaded through the adjusting block, and the adjusting pin is slidably connected within the first connecting frame. An adjusting frame is mounted on the side of the adjusting block. An adjusting column is rotatably connected within the adjusting frame via a connecting shaft. A guide frame is mounted on the lower surface of the adjusting column. A guide roller is rotatably connected within the guide frame and the adjusting column. A push rod motor is mounted on the upper surface of the adjusting column. A fixing plate is mounted on the output end of the push rod motor. A fixing column is mounted on the side of the fixing plate, and the fixing column passes through the guide frame. A fixing frame is mounted on the side of the fixing column. A fixing ball is rotatably connected inside the fixing frame. A pushing mechanism is bolted to the side of the fixing plate, and a dividing mechanism is bolted to the side of the adjusting column.

[0008] In a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to better move the dividing mechanism, the pushing mechanism includes a pushing plate and a pushing rod. The pushing plate is bolted to the side of the fixed plate, and the pushing rod is mounted on the side of the pushing plate.

[0009] In a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to better divide the PE film, the dividing mechanism includes an auxiliary frame and a cutting blade. The auxiliary frame is bolted to the side of the adjusting column, the outer surface of the push rod passes through the auxiliary frame, and the cutting blade is slidably connected to the auxiliary frame.

[0010] In a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to better guide the PE film, a first guide roller group is rotatably connected inside the first connecting frame, and a second guide roller group is rotatably connected inside the first connecting frame.

[0011] In a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to facilitate the operator to fix the PE film tube, a second connecting frame is installed on the side of the first connecting frame, an upper column is provided on the top of the inner wall of the second connecting frame, and a lower column is rotatably connected inside the second connecting frame.

[0012] In a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to better adjust the position of the PE film, a connecting block is installed on the side of the first connecting frame, and a connecting box is slidably connected to the outer side of the connecting block.

[0013] As a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to facilitate the operator to adjust the device, a connecting plate is installed inside the connecting box, and a threaded rod is rotatably connected inside the connecting plate, with the bottom end of the threaded rod rotatably connected inside the connecting box.

[0014] As a preferred embodiment of the PE film stretch wrapping machine of this utility model, in order to improve the performance of the device, the outer surface of the threaded rod is threaded with a threaded tube, and the side of the connecting block is mounted on the outer surface of the threaded tube.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] In this disclosure, a push rod motor drives a fixing plate to move to the right, which in turn moves a fixing column to the right and drives a fixing frame to the right. The PE film is then fixed by a fixing ball bearing. Compared with the prior art of directly cutting the PE film, this device can fix the broken part of the PE film, preventing the broken part from sticking together when the operator rewraps the goods.

[0017] In this disclosure, a cutting blade is moved along an auxiliary frame by a push rod, causing the cutting blade to cut the PE film. Compared with the prior art of directly tearing the PE film by hand, this device can cut the PE film at the break point evenly, avoiding uneven breaks after the operator cuts it, and making the PE film break point fit the new goods better.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-4 As shown, it illustrates a PE film stretch wrapping machine according to an embodiment of the present disclosure, which includes a first connecting frame 1, and further includes an adjusting block 2, an adjusting pin 3, an adjusting frame 4, an adjusting column 5, a guide frame 6, a guide roller 7, a push rod motor 8, a fixing plate 9, a fixing column 10, a fixing frame 11, a fixing ball 12, a pushing mechanism, and a dividing mechanism.

[0031] like Figure 3 and Figure 4As shown, the adjusting block 2 is slidably connected to the first connecting frame 1. An adjusting pin 3 is threaded through the adjusting block 2, and the adjusting pin 3 is slidably connected to the first connecting frame 1. An adjusting frame 4 is mounted on the side of the adjusting block 2. An adjusting column 5 is rotatably connected to the adjusting frame 4 via a connecting shaft. The damping between the connecting shaft and the adjusting frame 4 is relatively large, so after the operator moves the position of the adjusting column 5, the adjusting column 5 will not deviate during the guidance of the PE film. A guide frame 6 is mounted on the lower surface of the adjusting column 5. A guide roller 7 is rotatably connected to the guide frame 6 and the adjusting column 5. A push rod motor 8 is mounted on the upper surface of the adjusting column 5. The push rod motor 8 requires an external single-control switch to control its start and stop, and requires an external power supply. A fixing plate 9 is mounted on the output end of the push rod motor 8. A fixing column 10 is mounted on the side of the fixing plate 9, and the fixing column 10 passes through the guide frame 6. A fixing frame 11 is mounted on the side of the fixing column 10, and the fixing frame 11 rotates internally. A fixed ball bearing 12 is connected to the fixed plate 9. A pushing mechanism is bolted to the side of the fixed plate 9, and a dividing mechanism is bolted to the side of the adjusting column 5. The pushing mechanism and the dividing mechanism can change their installation positions according to the tilt angle of the adjusting column 5. The pushing mechanism includes a pushing plate 13 and a pushing rod 14. The pushing plate 13 is bolted to the side of the fixed plate 9, and the pushing rod 14 is bolted to the side of the pushing plate 13. The dividing mechanism includes an auxiliary frame 15 and a cutting blade 16. The auxiliary frame 15 is bolted to the side of the adjusting column 5, and the outer surface of the pushing rod 14 passes through the auxiliary frame 15. The cutting blade 16 is slidably connected to the auxiliary frame 15. The cutting blade 16 consists of an auxiliary block and a blade body. The auxiliary frame 15 has a transverse groove and a longitudinal groove inside. In the initial state, the auxiliary block is located in the transverse groove. When the pushing rod 14 contacts the auxiliary block, the auxiliary block falls freely from top to bottom along the longitudinal groove and then cuts the PE film by the blade body.

[0032] like Figure 2 and Figure 3 As shown, a first guide roller group 17 is rotatably connected inside the first connecting frame 1, and a second guide roller group 18 is rotatably connected inside the first connecting frame 1. Both the first guide roller group 17 and the second guide roller group 18 are composed of two sets of roller shafts. A second connecting frame 19 is installed on the side of the first connecting frame 1. An upper column 20 is provided on the top of the inner wall of the second connecting frame 19. A lower column 21 is rotatably connected inside the second connecting frame 19. A connecting block 27 is installed on the side of the first connecting frame 1. A connecting box 22 is slidably connected to the outer side of the connecting block 27. A connecting plate 23 is installed inside the connecting box 22. A threaded rod 24 is rotatably connected inside the connecting plate 23. The bottom end of the threaded rod 24 is rotatably connected inside the connecting box 22. A threaded tube 26 is threadedly sleeved on the outer surface of the threaded rod 24. The side of the connecting block 27 is installed on the outer surface of the threaded tube 26.

[0033] In this embodiment, as Figure 1As shown, a support frame 28 is mounted on the lower surface of the connecting box 22. A support plate 29 is rotatably connected inside the support frame 28 via a drive shaft. The bottom end of the drive shaft is connected to the output end of an external motor, allowing the external motor to provide power to the support plate 29. Figure 2 As shown, a drive motor 25 is mounted on the upper surface of the connecting plate 23. The output end of the drive motor 25 passes through the top of the threaded rod 24. The drive motor 25 is a forward and reverse motor. The drive motor 25 needs to be connected to an external single-control switch to control its start, stop, forward and reverse rotation. The drive motor 25 needs to be powered by an external power source.

[0034] In this embodiment, the upper column 20 is manipulated to move upward along the second connecting frame 19, and the paper tube of the PE film is placed on the outer surface of the lower column 21. The upper column 20 is manipulated to move downward along the second connecting frame 19 to contact the PE film paper tube. The adjusting block 2 is manipulated to move forward along the first connecting frame 1. The forward movement of the adjusting block 2 drives the adjusting frame 4 to move forward. The forward movement of the adjusting frame 4 drives the adjusting column 5 to move forward. The forward movement of the adjusting column 5 drives the guide frame 6 to move forward. The forward movement of the guide frame 6 drives the guide roller 7 to move forward. After the movement is complete, the adjusting pin 3 is tightened clockwise to fix the adjusting block 2.

[0035] The manipulator adjusts the column 5 by rotating it along the inside of the adjusting frame 4 via the connecting shaft, thereby adjusting the angle of the guide roller 7. The goods are placed on the support plate 29, and the PE film is passed through the inside of the first guide roller group 17 and the second guide roller group 18, and then through the outer surface of the guide roller 7 to wrap around the goods. The external motor is started, which drives the support plate 29 to rotate. The rotation of the support plate 29 causes the goods to rotate, which causes the PE film tube to drive the upper column 20 and the lower column 21 to rotate, so that the PE film extends out to wrap the goods.

[0036] Start the drive motor 25 and make it rotate forward. The output end of the drive motor 25 rotates and drives the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the threaded tube 26 to move upward. The upward movement of the threaded tube 26 drives the connecting block 27 to move upward. The connecting block 27 moves upward along the connecting box 22 and drives the first connecting frame 1 to move upward, gradually lifting the PE film upward so that the PE film wraps the goods upward.

[0037] After the PE film is wrapped around the goods, the output end of the control drive motor 25 is reversed. The output end of the drive motor 25 rotates, which drives the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the threaded tube 26 to move downward. The downward movement of the threaded tube 26 drives the connecting block 27 to move downward. The connecting block 27 moves downward along the connecting box 22, which drives the first connecting frame 1 to move downward, gradually moving the PE film downward so that the PE film wraps the goods downward, thus wrapping the goods a second time.

[0038] After the package is finished, turn off the external motor and drive motor 25, start the push rod motor 8, the output end of the push rod motor 8 moves to the right, driving the fixing plate 9 to move to the right, the fixing plate 9 moves to the right, driving the fixing column 10 to move to the right, the fixing column 10 moves to the right, driving the fixing frame 11 to move to the right, the fixing frame 11 moves to the right, driving the fixing ball 12 to move to the right, so that the fixing ball 12 fixes the PE film on the guide roller 7.

[0039] At the same time, the fixed plate 9 moves to the right, causing the push plate 13 to move to the right. The push plate 13 moves to the right, causing the push rod 14 to move to the right. The push rod 14 moves to the right along the auxiliary frame 15. The push rod 14 moves to the right, pushing the cutter 16 to move to the right along the transverse groove. After moving a certain distance along the transverse groove, the cutter 16 falls freely downwards along the longitudinal groove, so that the cutter 16 cuts the PE film, making the cut end of the PE film relatively flat, avoiding the situation where the PE film is difficult to adhere to the goods when reused.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
