Description

Technical Field

[0001] The present application relates to the field of packaging film processing technologies, and particularly relates to an auxiliary insertion plate for an embossing machine. Background Art

[0002] Plastic packaging films are common packaging materials. A packaging film that can carry 10 kg - 50 kg of solid particles or powdered materials is generally referred to as a heavy packaging film. During the production of a heavy packaging film, first, a blown film is formed by blow molding. The blown film formed by blow molding is a continuous tubular structure. Then, graphic information is printed on the blown film, and then the blown film is wound and stored.

[0003] The device for printing graphic information on the blown film is an embossing machine. The embossing machine includes two embossing rollers and two sets of guiding rollers. The distance between the two sets of guiding rollers gradually decreases in the direction close to the embossing rollers. Under the guiding action of the two sets of guiding rollers, the continuous tubular structure of the blown film gradually forms a flat structure. A pair of auxiliary insertion plates are provided between the two sets of guiding rollers, and the auxiliary insertion plates are used to limit the position of the blown film along the axial direction of the embossing rollers.

[0004] According to the usage requirements of the blown film, the auxiliary insertion plates need to be set in an angle-adjustable form. Currently, the inclination angles of the two auxiliary insertion plates need to be adjusted separately. When adjusting the two auxiliary insertion plates, it is necessary to pay attention to keeping the two auxiliary insertion plates symmetrical, and the adjustment process is relatively inconvenient. Utility Model Content

[0005] In order to improve the problem of inconvenient angle adjustment of the auxiliary insertion plates in a blown film embossing machine, the present application provides an auxiliary insertion plate for an embossing machine.

[0006] An auxiliary insertion plate for an embossing machine provided by the present application adopts the following technical solution:

[0007] An auxiliary insertion plate for an embossing machine includes a base and an outer frame. The outer frame is installed on the base in a lifting manner. The outer frame is used to be installed around two guiding roller groups of an embossing machine. Two insertion plates are hingedly arranged inside the outer frame. The two insertion plates are used to be installed between the two guiding roller groups. A connecting rod is rotatably arranged on the back of the insertion plate. The connecting rod is connected to the base. The connecting rod is provided with a locking structure, and the locking structure can limit the relative rotation between the connecting rod and the insertion plate.

[0008] By adopting the above technical solution, the inclination angles of the two inserting plates can be adjusted as needed. When adjusting the inclination angles of the inserting plates, loosen the locking structures of the corresponding two inserting plates, and then move the outer frame up and down to drive the inserting plates to rotate so as to adjust the rotation angles of the inserting plates. After the inserting plates rotate to the desired angles, use the locking structures to lock the connecting rods and the inserting plates again to keep the angles of the inserting plates fixed. During the process of adjusting the inclination angles of the inserting plates, the two inserting plates change synchronously under the drive of the outer frame, making it easier to adjust the angles of the two inserting plates.

[0009] Optionally, the width of the inserting plate gradually decreases from top to bottom, and the thickness of the inserting plate gradually increases from top to bottom.

[0010] By adopting the above technical solution, the width of the inserting plate is set to gradually decrease from top to bottom to adapt to the change in the spacing of the guide roller group. The thickness of the inserting plate is set to gradually increase from top to bottom, so that the smaller-width end of the inserting plate has a larger thickness, preventing a pointed part from being formed at the lower end of the inserting plate, thereby reducing the situation where the inserting plate scratches the blown film and improving the strength of the lower end of the inserting plate.

[0011] Optionally, the lower ends of the inserting plates are provided with rounded corners, and the rounded corners at the lower ends of the two inserting plates are arranged oppositely.

[0012] By adopting the above technical solution, the rounded corners at the lower ends of the two inserting plates are arranged oppositely, which can further reduce the scratching effect of the lower ends of the inserting plates on the blown film.

[0013] Optionally, polytetrafluoroethylene layers are provided on the opposite sides of the two inserting plates.

[0014] By adopting the above technical solution, the polytetrafluoroethylene material has self-lubricating properties. By providing polytetrafluoroethylene layers on the opposite sides of the two inserting plates, the frictional effect between the inserting plates and the blown film can be reduced.

[0015] Optionally, a mounting seat is connected between the outer frame and the inserting plate. The inserting plate is fixedly installed on the mounting seat, and the mounting seat is hinged to the outer frame.

[0016] By adopting the above technical solution, the outer frame and the inserting plate are connected through the mounting seat, which facilitates the installation of the inserting plate.

[0017] Optionally, the locking structure includes a clamping plate and a hand-twist bolt. The clamping plate is connected to the mounting seat, and the hand-twist bolt is threadedly connected to the mounting seat. The hand-twist bolt is used to force the clamping plate to clamp the connecting rod.

[0018] By adopting the above technical solution, the locking action of the locking structure on the connecting rod is realized by the tightening and loosening actions of the hand-twist bolt, making it easier to tighten and loosen the connecting rod.

[0019] Optionally, the connecting rod is a hollow tube structure.

[0020] By adopting the above technical solution, the connecting rod is arranged as a hollow structure, which is beneficial to reducing the overall weight of the mechanism. Moreover, when the hand-twist bolt forces the clamping plate to clamp the connecting rod, the connecting rod with a hollow structure is prone to undergo a small elastic deformation, which is beneficial to increasing the locking degree of the connecting rod.

[0021] Optionally, the outer frame is a rod frame, the outer frame is provided with a plurality of guide plates, the guide plates are provided with lifting guide grooves, the rods of the outer frame pass through the lifting guide grooves, and the guide plates are used for fixedly connecting with the roller frames of the guide roller group.

[0022] By adopting the above technical solution, the rods of the outer frame pass through the lifting guide grooves, so that the guide plates form a vertical guiding effect on the outer frame, and the outer frame is liftably installed on the two guide roller groups.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During the process of adjusting the inclination angle of the insertion plate, the two insertion plates change synchronously under the drive of the outer frame, making it easier to adjust the angles of the two insertion plates.

[0025] 2. The rods of the outer frame pass through the lifting guide grooves, so that the guide plates form a vertical guiding effect on the outer frame, and the outer frame is liftably installed on the two guide roller groups. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following further Figures 1 - 3 elaborates on the present application in detail with reference to the attached

[0032] This embodiment of the present application discloses an auxiliary insertion plate 3 for an embossing machine. Refer to Figure 1 As shown, the auxiliary insertion plate 3 for the embossing machine includes a base 1 and an outer frame 2. The outer frame 2 is installed on the base 1 in a lifting manner. The outer frame 2 is used to be installed around two guide roller sets 7 of the embossing machine. There are two insertion plates 3 on the inner side of the outer frame 2. An installation seat 4 is connected between the insertion plate 3 and the outer frame 2. The insertion plate 3 is fixedly installed on the installation seat 4. The installation seat 4 is hinged to the outer frame 2. The two insertion plates 3 are used to be installed between the two guide roller sets 7. A connecting rod 5 is rotatably arranged on the back of the insertion plate 3. The connecting rod 5 is connected to the base 1. The connecting rod 5 is provided with a locking structure 6, and the locking structure 6 can limit the relative rotation between the connecting rod 5 and the insertion plate 3.

[0033] Refer to Figure 1 and Figure 2 As shown, the outer frame 2 is a square rod frame. The outer frame 2 has two cross bars 21 and two longitudinal bars 22. Connecting rods 23 are fixedly arranged on both cross bars 21. The two connecting rods 23 are respectively hinged to the two corresponding installation seats 4. Each longitudinal bar 22 is respectively provided with two guide plates 24. The guide plates 24 are used to be fixedly connected to the roller frames of the guide roller sets 7. The guide plates 24 are provided with lifting guide grooves 241. The rods of the outer frame 2 pass through the lifting guide grooves 241, so that the outer frame 2 is installed on the roller frames of the guide roller sets 7 in a liftable manner.

[0034] Refer to Figure 1 As shown, a lifting driving member 8 for driving the lifting movement of the outer frame 2 is installed on the base 1. The lifting driving member 8 is an electric cylinder or an oil cylinder. In another embodiment, the lifting driving member 8 can be omitted, and the adjustment of the outer frame 2 is replaced by a manual adjustment method.

[0035] Refer to Figure 3 As shown, the width of the insertion plate 3 gradually decreases from top to bottom to adapt to the change in the distance between the two guide roller sets 7. The thickness of the insertion plate 3 gradually increases from top to bottom, so as to strengthen the strength of the lower end of the insertion plate 3. A fillet 31 is provided at the lower end of the insertion plate 3. The fillets 31 at the lower ends of the two insertion plates 3 are arranged oppositely. The lower end of the insertion plate 3 contacts the blown film through the fillet 31, which can reduce the scraping effect of the lower end of the insertion plate 3 on the blown film.

[0036] In order to reduce the frictional force between the insertion plate 3 and the blown film, a polytetrafluoroethylene layer is provided on the opposite sides of the two insertion plates 3. Utilizing the self-lubricating property of the polytetrafluoroethylene material, the resistance when the blown film passes through the insertion plate 3 can be reduced.

[0037] Refer to Figure 2, the locking structure 6 includes a clamping plate 61 and a hand-twist bolt 62. One side of the clamping plate 61 is fixedly connected to the mounting seat 4, and there is a separation between the side of the clamping plate 61 away from the fixed side and the mounting seat 4. An installation space for accommodating the connecting rod 5 is formed between the clamping plate 61 and the mounting seat 4. The hand-twist bolt 62 is threadedly connected to the mounting seat 4, and the hand-twist bolt 62 passes through the clamping plate 61. When the hand-twist bolt 62 is tightened, it can force the clamping plate 61 to clamp the connecting rod 5. In this embodiment, the connecting rod 5 is arranged as a hollow tube structure. In this way, when the clamping plate 61 clamps the connecting rod 5, the connecting rod 5 can undergo a small elastic deformation, making the clamping effect of the clamping plate 61 on the connecting rod 5 more stable and reliable.

[0038] The implementation principle of the auxiliary insertion plate 3 for a embossing machine in the embodiment of the present application is as follows: When embossing a blown film, the blown film enters the embossing roller after being guided by two guide roller groups 7. The blown film passing through the guide roller group 7 is limited by the two insertion plates 3, and the two insertion plates 3 can control the position of the blown film along the axial direction of the embossing roller.

[0039] The inclination angles of the two insertion plates 3 can be adjusted as needed. When adjusting the inclination angles of the insertion plates 3, loosen the locking structures 6 of the corresponding two insertion plates 3, and then move the outer frame 2 up and down, so that the outer frame 2 drives the insertion plates 3 to rotate to adjust the rotation angle of the insertion plates 3. When the insertion plates 3 rotate to the required angle, then use the locking structure 6 to lock the connecting rod 5 and the insertion plates 3 again to keep the angles of the insertion plates 3 fixed. During the above process of adjusting the inclination angles of the insertion plates 3, the two insertion plates 3 change synchronously under the drive of the outer frame 2, making it easier to adjust the angles of the two insertion plates 3.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
