Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically to an automatic film clamping, cutting, and pressing integrated device and a stretch wrapping machine. Background Technology
[0002] In the coupling agent production process, coupling agent granules or powders need to be bagged and placed on pallets before being shipped out, and then wrapped with stretch film. Most existing stretch film machines require manual film stretching and application at the start of operation; that is, the film is manually stretched and attached or tied to the outer surface of the goods (pallet). After the wrapping is completed, the film needs to be manually cut. Because the stretch film has a certain degree of elasticity and is stretched to a certain length during wrapping, cutting can cause the cut edge to spring back and fall off. The cut fragments of film need to be manually reattached to the outer surface of the goods. This process not only consumes a large amount of manual labor but also severely restricts production efficiency.
[0003] Chinese Patent Publication No. CN217294997U discloses a film-cutting mechanism on an online pallet wrapping machine, including a worktable with a support frame fixedly installed on it. The mechanism also includes a turntable rotatably connected to the worktable, with a hollow interior; and multiple sets of clamping plates equidistantly distributed around the axis of the turntable, which are slidably connected to the turntable. After wrapping the goods, when film cutting is required, a second cutter pushes the film into a cutting groove, abutting against the first cutter, thus cutting the film. The first cutter, under spring pressure, remains abutting against the second cutter, improving the film-cutting effect. However, because the ends of the film break are not restricted, it may spring back and fall off at the moment of breakage, requiring manual application of the film tail to the outer surface of the goods after cutting. Summary of the Invention

One end of the clamping mounting rod is perpendicularly fixed to the extended end of the third cylinder, the fixed clamping jaw is perpendicularly fixed to the other end of the clamping mounting rod, the fifth cylinder is fixed to the top of the clamping mounting rod, and the extended end of the fifth cylinder is fixedly connected to the movable clamping jaw. The fixed clamping jaw and the movable clamping jaw correspond to each other.
[0010] In a further optimized technical solution, the clamping surfaces of the fixed gripper and the movable gripper are provided with silicone pads.
[0011] In a further optimized technical solution, the support frame includes an L-shaped rod and a crossbar. The short side of the L-shaped rod is hinged to the base, and the long side of the L-shaped rod has an elongated hole. The crossbar is inserted into the elongated hole. The long side of the L-shaped rod has several first positioning holes that pass through the elongated hole. The crossbar has several second positioning holes that correspond to the first positioning holes. After the first positioning holes and the second positioning holes are aligned, fixing bolts are inserted.
[0012] This utility model also proposes a wrapping machine for stretch film, including the aforementioned automatic film clamping, cutting, and pressing integrated device, a column, a film frame assembly, and a rotating disk. The column is vertically fixed on the base, the film frame assembly is movably mounted on the column, and the rotating disk is rotatably mounted on the base and corresponds to the automatic film clamping, cutting, and pressing integrated device.
[0013] In a further optimized technical solution, a lead screw is provided inside the column, one end of which is connected to the first motor through a transmission component, and a nut assembly is sleeved in the middle of the lead screw.

[0015] The beneficial effects of this utility model include: after the stretch film is wrapped around the goods, the first cylinder drives the integrated film clamping, cutting, and pressing device to rotate, causing the first pressing roller on the actuator to press the end of the stretch film tightly against the surface of the goods. The third cylinder drives the clamping component to descend, clamping the stretch film. The fourth cylinder drives the film end heat-cutting component to rotate and flip out, heat-cutting the stretch film. Because the cut end of the stretch film on the goods side is pressed by the first pressing roller, the stretch film will not spring back at the moment of cutting, preventing the cut end from scattering and falling off, thus ensuring the stretch film's... The film tail is tightly attached to the surface of the goods, and the cut end of the wrapping film on the side of the actuator is held in place by the clamping component, preventing it from scattering. When wrapping for the next time, after the first pressure roller touches the surface of the goods, the second cylinder drives the actuator to continue rotating, so that the second pressure roller presses the wrapping film onto the surface of the goods. The clamping component releases the wrapping film, and the wrapping of the goods can begin. This solves the problems of relying on manual handling, easy loosening, and low efficiency in wrapping film packaging. At the same time, the film tail does not need to be reserved for excessive manual operation, avoiding waste of wrapping film. Attached Figure Description

[0028] Please see Figure 1 , Figures 3 to 6The automatic film clamping, cutting, and pressing integrated device 1 disclosed in this utility model includes a support frame 11 and an execution component 12. The support frame 11 is rotatably mounted on a base 2, and a first cylinder 3 is hinged to the base 2. The extended end of the first cylinder 3 is hinged to the side wall of the support frame 11 to drive the support frame 11 to rotate. The execution component 12 is rotatably mounted at the end of the support frame 11, and a second cylinder 4 is hinged to the side wall of the support frame 11. The extended end of the second cylinder 4 is hinged to the execution component 12. Used to drive the actuator 12 to rotate; the actuator 12 includes a mounting frame 121, a first pressure roller 122, a second pressure roller 123, a clamping member 124, and a film tail cutting member 125. The mounting frame 121 is rotatably connected to the end of the support frame 11. The two ends of the first pressure roller 122 are rotatably mounted on the end of the mounting frame 121 via mounting seats 126. The second pressure roller 123 is located on one side of the middle of the mounting frame 121. A third cylinder 127 is vertically installed inside the mounting frame 121. The protruding end of cylinder 127 extends through the top of mounting frame 121. Clamping member 124 is located on the protruding end of third cylinder 127 and is lifted and lowered under the drive of third cylinder 127. Film tail heat-cutting member 125 is rotatably mounted on mounting frame 121. A fourth cylinder 128 is hinged to one side of mounting frame 121, and the protruding end of fourth cylinder 128 is hinged to film tail heat-cutting member 125. Specifically, a torsion spring 129 is provided on the rotating shaft of first pressure roller 122 that rotates relative to mounting frame 121. The mounting frame 121 is provided with a limiting block 130 corresponding to the mounting base 126. Under the cooperation of the torsion spring 129 and the limiting block 130, the first pressing roller 122 is kept in a straight line with the mounting frame 121 in the initial state. The clamping member 124 and the film tail heat-breaking member 125 are arranged between the first pressing roller 122 and the second pressing roller 123, and the film tail heat-breaking member 125 is arranged in front of the clamping member 124, that is, the film tail heat-breaking member 125 is between the first pressing roller 122 and the clamping member 124.In this embodiment, after the stretch film 8 is wrapped around the goods, the first cylinder 3 drives the film clamping, cutting, and pressing integrated device 1 to rotate, so that the first pressing roller 122 on the execution component 12 presses the film tail of the stretch film 8 tightly against the surface of the goods. The third cylinder 127 drives the clamping member 124 to descend, so that the clamping claws of the clamping member 124 insert into both sides of the stretch film 8 and clamp the stretch film 8. The fourth cylinder 128 drives the film tail heat-cutting member 125 to rotate and flip out to contact the stretch film 8, heat-cutting the stretch film 8. Since the cut side of the film tail of the stretch film 8 located on the goods side is pressed by the first pressing roller 122, the stretch film 8 will not spring back at the moment of breaking, causing the cut end of the film tail to fall off, so that the cut end of the stretch film 8 is tightly attached to the surface of the goods. Furthermore, the cut end of the stretch film 8 located on one side of the execution component 12 is held in place by the clamping member 124 and will not scatter. When performing the next wrapping, the clamping member 124 holds the stretch film 8 in place. After the first cylinder 3 drives the first pressure roller 122 to press against the surface of the goods, the second cylinder 4 drives the execution component 12 (mounting frame 121) to continue rotating, so that the second pressure roller 123 presses the stretch film 8 onto the surface of the goods. The clamping member 124 releases the stretch film 8 and rises under the drive of the third cylinder 127, and the wrapping of the goods can begin. This solves the problems of relying on manual labor, easy loosening, and low efficiency in the handling of film tails in stretch film packaging. At the same time, the film tail does not need to reserve an excessively long length for manual operation, avoiding waste of the stretch film 8.
[0029] In a specific example, the film tail heat-cutting component 125 includes a heating wire 1251, a heating fixing rod 1252, and a rotating shaft 1253. The rotating shaft 1253 is vertically rotatably mounted on the mounting frame 121. The heating fixing rods 1252 are fixed to both ends of the rotating shaft 1253, and both ends of the heating wire 1251 are fixed to the head ends of the two heating fixing rods 1252. The tail end of the top heating fixing rod 1252 is hinged to the extended end of the fourth cylinder 128. When the film tail heat-cutting component 125 is not in operation, the heating wire 1251 rests against one side of the mounting frame 121. When it is necessary to heat-cut the wrapping film, it rotates and flips out under the drive of the fourth cylinder 128 to contact the wrapping film 8 for heat-cutting. The heating wire 1251 uses pulse heating, and is energized only for the moment of heat-cutting to avoid high-temperature burns to heat-sensitive goods.
[0030] In a specific example, the clamping component 124 includes a clamping mounting rod 1241, a fifth cylinder 1242, a fixed gripper 1243, and a movable gripper 1244. One end of the clamping mounting rod 1241 is perpendicularly fixed to the extended end of the third cylinder 127. The fixed gripper 1243 is perpendicularly fixed to the other end of the clamping mounting rod 1241. The fifth cylinder 1242 is fixed to the top of the clamping mounting rod 1241, and the extended end of the fifth cylinder 1242 is fixedly connected to the movable gripper 1244. The fixed gripper 1243 and the movable gripper 1244 correspond to each other. Under the extension and retraction of the fifth cylinder 1242, the movable gripper... 1244 can approach the fixed gripper 1243 for clamping. Specifically, the clamping surfaces of the fixed gripper 1243 and the movable gripper 1244 are provided with silicone pads 1245. The fixed gripper 1243 and the movable gripper 1244 are arranged in parallel. When it is necessary to clamp the wrapping film, the third cylinder 127 drives the mounting rod 1241 to descend. The wrapping film 8 passes through the gap at the bottom of the fixed gripper 1243 and the movable gripper 1244 and enters between the fixed gripper 1243 and the movable gripper 1244. Then, the fifth cylinder 1242 drives the movable gripper 1244 to move towards the side of the fixed gripper 1243 for clamping.
[0031] In a preferred embodiment, the support frame 11 includes an L-shaped rod 111 and a crossbar 112. The short side of the L-shaped rod 111 is hinged to the base 2, ensuring that the support frame 11 can rotate horizontally on the base 2. An elongated hole 113 is provided on the long side of the L-shaped rod 111. The crossbar 112 is inserted into the elongated hole 113 and its height and insertion length can be adjusted vertically and horizontally. Several first positioning holes 114 are provided on the long side of the L-shaped rod 111, passing through the elongated hole 113. Several second positioning holes 115 are provided on the crossbar 112, corresponding to the first positioning holes 114. When the crossbar 112 is inserted into the elongated hole 113, after the first positioning holes 114 and the second positioning holes 115 are aligned, a fixing bolt 116 is inserted. When the pallet height of the goods to be wrapped and packaged is different, and when the size of the goods is different, the height and horizontal position of the actuator 12 can be adjusted by adjusting the height and horizontal extension position of the crossbar 112 to adapt to different working spaces. Example
[0032] Please see Figures 1 to 7This utility model also discloses a stretch film packaging machine, including the aforementioned automatic film clamping, cutting, and pressing integrated device 1, column 5, film frame assembly 6, and rotating disk 7. The column 5 is vertically fixed on the base 2. The film frame assembly 6 is movably mounted on the column 5. The rotating disk 7 is rotatably mounted on the base 2 and corresponds to the automatic film clamping, cutting, and pressing integrated device 1, meaning that the automatic film clamping, cutting, and pressing integrated device 1 can move closer to or away from the working area of the rotating disk 7 by rotation. Specifically, the column 5 is a hollow rectangular structure. A lead screw 51 is rotatably mounted inside the column 5. The lead screw 51 is parallel to the length of the column 5. The bottom end of the lead screw 51 passes through the base 2 and is connected to the first motor 53 through a transmission component 52. A nut pair 54 is sleeved in the middle of the lead screw 51. A lifting hole 55 is opened on one side of the column 5. The back of the film frame assembly 6 passes through the lifting hole 55 and is fixedly connected to the nut pair 54. Specifically, the transmission component 52 is a gear set, the first motor 53 is a servo motor, the first motor 53 drives the lead screw 51 to rotate forward and backward, thereby driving the film frame assembly 6 to rise and fall along the column 5. The rotating disk 7 is existing technology, and its structure will not be described in detail. It is sufficient to drive the goods to be wrapped and packaged to rotate.
[0033] In a specific example, the film frame assembly 6 includes a U-shaped frame 61, a second motor 62, a pre-stretch roller group 63, a pressure roller group 64, an unwinding shaft 65, and a tension roller group 66. A connecting rod 67 is provided on the back of the U-shaped frame 61. The connecting rod 67 passes through the lifting hole 54 and is fixedly connected to the nut pair 53. The second motor 62 is located on the U-shaped frame 61. The pre-stretch roller group 63 is connected to the second motor 62 through a multi-stage gear transmission component. The unwinding shaft 65 is vertically located on one side of the U-shaped frame 61. The pressure roller group 64 is located on the flip plate 68 and corresponds to the pre-stretch roller group 63. The bottom end of the flip plate 68 is hinged to the bottom end of the opening of the U-shaped frame 61. The tension roller group 66 is located on the other side of the U-shaped frame 61. When installing the stretch film roll, insert the stretch film roll onto the unwinding shaft 65, pull the stretch film out between the pre-stretch roller group 63 and the tension roller group 66, close the flip plate 68, and the tension roller group 66 provides reverse pressure to press the stretch film onto the surface of the two pre-stretch roller groups 63 and form a wedge angle with the pre-stretch roller groups 63, thereby increasing the film coverage area. The second motor 62 drives the pre-stretch roller group 63 to form differential stretching through a multi-stage gear transmission component. The stretched stretch film passes through the tension roller group 66, and the tension roller group 66 generates reverse resistance through spring loading, which counteracts the tension fluctuation caused by the inertia of the film roll in real time. By pre-stretching the stretch film 8 on the film frame assembly 6 before wrapping and packaging goods, the amount of stretch film 8 used is reduced.
