Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, and in particular to a bag making machine hot stamping mechanism. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses and specifications made of plastic or other materials. Generally speaking, plastic packaging bags are the main product. The bag-making machine is equipped with a hot-pressing and hole-cutting mechanism.

[0003] Authorization announcement number CN209580666U discloses a hot-pressing bag machine for bag making, including a roller and a tray. A feeding roller is arranged above the roller, and the rotating shaft of the feeding roller passes through a bearing seat. The bearing seat is connected to a first guide rod, which passes through a first fixed plate. The first guide rod is connected to a second guide rod by a traction rope. A cam is connected to the top of the second guide rod, which passes through a second fixed plate. A first clamping plate is arranged at the bottom of the second guide rod, and a hot-pressing plate is connected to the bottom of the second guide rod. The first clamping plate is connected to the second clamping plate by a spring. The hot-pressing plate is located above the tray. When the hot-pressing plate is used to seal and cut the film roll, the feeding roller is lifted by a linkage mechanism, and no material is fed at this time. Therefore, the film roll will not accumulate, thereby avoiding wrinkles during the next sealing and ensuring the sealing quality.

[0004] Existing hot stamping machines for bag making have shortcomings: their overall structure is complex, they lack a perforation mechanism, and they cannot cut easy-tear grooves on the packaging bag during sealing. Therefore, we propose a hot stamping mechanism for bag making machines. Summary of the Invention

[0005] The main purpose of this utility model is to provide a hot-seal bag making machine mechanism that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A bag-making machine's hot-pressing mechanism includes a support plate, a gantry frame, and a shelf. The gantry frame is fitted onto the top of the support plate. A reciprocating lead screw is rotatably connected to the gantry frame via a bearing. An internally threaded slider is fitted onto the outer side of the reciprocating lead screw. A shelf is bolted to one side of the internally threaded slider. A temperature controller is mounted on one end of the shelf via a mounting base. A lead screw is threaded through the top of the shelf via a threaded groove. A structural plate is rotatably connected to the bottom end of the lead screw via a bearing. A hot-pressing roller is mounted on the bottom of the structural plate via a mounting bracket. Electric heating wires are embedded equidistantly inside the hot-pressing roller. An auxiliary roller is mounted on the bottom of the structural plate on one side of the hot-pressing roller via a mounting bracket. Piercing cones are fixed equidistantly to the outer side of the auxiliary roller via threaded grooves.

[0007] Furthermore, a second auxiliary rod is fixed inside the bottom of the reciprocating lead screw of the gantry frame by bolts, and the second auxiliary rod passes through the internal threaded slider.

[0008] Furthermore, the top two ends of the structural plate are connected to a first auxiliary rod via threaded grooves, and the first auxiliary rod penetrates the layer plate.

[0009] Furthermore, the detection end of the temperature controller is located inside the hot-pressing roller, and the current output end of the temperature controller is electrically connected to the current input end of the heating wire through a power cord. The hot-pressing roller is made of graphene material; the hot-pressing roller made of graphene material has good thermal conductivity.

[0010] Furthermore, a drive motor is mounted on one end of the gantry frame via a mounting bracket, and the output shaft of the drive motor is connected to one end of a reciprocating lead screw via a connecting sleeve.

[0011] Furthermore, the gantry frame has slots on both sides, and the bearing plate has fixing bolts connected to both ends by threaded grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The temperature controller's set value controls the heating wire to heat the hot-pressing roller. The rotating screw pushes the structural plate down, causing the heated hot-pressing roller and the auxiliary roller's outer piercing cone to move onto the bag opening. The drive motor works, driving the heated hot-pressing roller and auxiliary roller to rotate at the bag opening via the reciprocating screw and internal thread slider. The heated hot-pressing roller seals the bag, while the auxiliary roller presses and pierces the bag opening with the piercing cone, thus cutting an easy-tear groove. Attached Figure Description

Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a bag-making machine's hot-stamping mechanism includes a support plate 1, a gantry frame 2, and a shelf 3. The gantry frame 2 is fitted onto the top of the support plate 1. A reciprocating screw 4 is rotatably connected to the gantry frame 2 via a bearing. An internally threaded slider 5 is fitted onto the outside of the reciprocating screw 4. A shelf 3 is fixed to one side of the internally threaded slider 5 by bolts. A temperature controller 8 is mounted on one end of the shelf 3 via a mounting seat. A screw 6 is threaded through the top of the shelf 3 via a threaded groove. A structural plate 7 is rotatably connected to the bottom of the screw 6 via a bearing. A hot-stamping roller 9 is mounted on the bottom of the structural plate 7 via a mounting bracket. Electric heating wires 14 are embedded equidistantly inside the hot-stamping roller 9. An auxiliary roller 10 is mounted on the bottom of the structural plate 7 on one side of the hot-stamping roller 9 via a mounting bracket. Piercing cones 15 are fixed equidistantly to the outside of the auxiliary roller 10 via threaded grooves.

[0020] Among them, such as Figure 1 As shown, the gantry frame 2 is located inside the bottom of the reciprocating screw 4 and is fixed with a second auxiliary rod 13 by bolts. The second auxiliary rod 13 passes through the internal thread slider 5. The setting of the second auxiliary rod 13 can improve the structural stability of the internal thread slider 5 without affecting its movement.

[0021] Among them, such as Figure 2 As shown, the top two ends of the structural plate 7 are connected to a first auxiliary rod 12 through threaded grooves. The first auxiliary rod 12 penetrates the layer plate 3. The first auxiliary rod 12 can prevent the structural plate 7 from rotating with the lead screw 6 without affecting its up and down movement.

[0022] Among them, such as Figure 2 and Figure 3 As shown, the detection end of the temperature controller 8 is located inside the hot bag roller 9. The current output end of the temperature controller 8 is electrically connected to the current input end of the electric heating wire 14 through the power cord. The hot bag roller 9 is made of graphene material. Setting the set value of the temperature controller 8 can control the heating of the electric heating wire 14 and its heating temperature.

[0023] Among them, such as Figure 1As shown, a drive motor 18 is mounted on one end of the gantry frame 2 via a mounting bracket. The output shaft of the drive motor 18 is connected to one end of the reciprocating lead screw 4 via a connecting sleeve. When the drive motor 18 is working, it can drive the reciprocating lead screw 4 to rotate.

[0024] Among them, such as Figure 1 As shown, the gantry frame 2 has slots 16 on both sides, and the bearing plate 1 has fixing bolts 17 connected to both ends through threaded grooves. Tightening the fixing bolts 17 so that one end is inserted into the slot 16 can fix the gantry frame 2 after it moves up and down.

[0025] It should be noted that this utility model is a bag-heating mechanism for a bag-making machine. During operation, the operator uses bolts to install the support plate 1 onto the bag-making machine. The bag-making machine processes film and plastic film into packaging bags. When the packaging bags move, their openings are moved into the gantry 2 located on the support plate 1. The operator sets the set value of the temperature controller 8 to control the heating of the electric heating wire 14. The heat-heating roller 9, made of graphene material, has good thermal conductivity and can quickly absorb the temperature after being heated by the electric heating wire 14. The operator holds the rocker plate 11 and rotates the screw 6 to push the structural plate 7. The rollers are moved downwards, causing the piercing cones 15 on the outside of the heated ironing rollers 9 and auxiliary rollers 10 to move onto the opening of the packaging bag. The drive motor 18 is turned on to drive the reciprocating screw 4 to rotate. The rotation of the reciprocating screw 4 pushes the internal thread slider 5 and the shelf 3 on one side to move. The movement of the shelf 3 causes the heated ironing rollers 9 and auxiliary rollers 10 to rotate at the opening of the packaging bag. The heated ironing rollers 9 rotate to seal the packaging bag, and the auxiliary rollers 10 rotate to press and pierce the opening of the packaging bag through the piercing cones 15, thereby cutting out the easy-tear groove.

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 illustrative of the principles of this utility model.
