Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a novel heating integrated device for packaging machines. Background Art

[0002] In the packaging process, for PP, PE and aluminum foil bags, after filling, the bag mouth is generally sealed by heating and melting the bag mouth to make it stick together, which is called heat sealing. Generally, a heating strip is used for heating. During heating, in order to ensure that the bag melts and does not stick to the heating strip, a thin cloth made of polytetrafluoroethylene is used to isolate the heating strip and the bag. The principle of heating and melting is to energize both ends of the heating strip. The heating strip is used as a resistor to generate heat, so a wire is connected to each end of the heating strip. These two wires are connected to the temperature controller, and the heating temperature and time are controlled by controlling the current.

[0003] Existing heating blocks have the following disadvantages:

[0004] 1. The entire heating block is fixed and installed with multiple bolts. When maintenance is required, the bolts need to be removed repeatedly, which is time-consuming and laborious;

[0005] 2. The heat-resistant polytetrafluoroethylene cloth used for isolation is generally glued to the heating block with tape. Since the polytetrafluoroethylene cloth and the heating strip are both vulnerable parts, they need to be replaced at any time when their service life is reached, and the glued method is not easy to replace;

[0006] 3. The wires at both ends of the heating strip are exposed, which looks messy and unsightly, and also poses a safety hazard. Utility Model Content

[0007] The utility model aims to provide a novel heating integrated device for a packaging machine.

[0008] A novel packaging machine heating integrated device comprises a mounting plate, a heating block body and a polytetrafluoroethylene cloth. The heating block body is detachably arranged at the bottom of the mounting plate by a clamping device, a heating strip is arranged at the bottom of the heating block body, and the polytetrafluoroethylene cloth is adjustably arranged below the heating strip by a polytetrafluoroethylene cloth adjusting device arranged on the heating block body.

[0009] Furthermore, the polytetrafluoroethylene cloth adjustment device includes cavity one and cavity two, and the cavity one and cavity two are respectively opened on the front and rear sides of the heating block body, and the active winding rod and the driven winding rod are rotatably arranged in the cavity one and cavity two respectively, and the outside of the driven winding rod is wrapped with polytetrafluoroethylene cloth, and the outer end of the polytetrafluoroethylene cloth passes around the bottom of the heating strip and is fixedly connected to the active winding rod.

[0010] Furthermore, the clamping device includes a fixed block, a sliding block and a clamping block, two sliding blocks are arranged in parallel on the top of the heating block body, a fixed block is fixedly arranged on one side of the mounting plate, a sliding groove is arranged between the mounting plate and the fixed block, one of the sliding blocks is slidably connected to the sliding groove, and a clamping block is adjustably arranged on the other side of the mounting plate through a clamping bolt, and the clamping block cooperates with the other sliding block.

[0011] Furthermore, a wire threading groove is opened inside the slider, and a left insulating plate and a right insulating plate are respectively arranged on the left and right sides of the lower part of the heating block body, and the wires at both ends of the heating strip respectively pass through the left insulating plate, the right insulating plate and the wire threading groove.

[0012] Furthermore, a knob is provided on the outside of the heating block body, and one end of the active winding rod passes through the outside of the heating block body and is fixedly connected to the knob.

[0013] In summary, the utility model has the following beneficial effects:

[0014] The polytetrafluoroethylene cloth of the utility model can be set under the heating strip without using tape. The position of the polytetrafluoroethylene cloth can be moved by turning the knob, so that the unused polytetrafluoroethylene cloth is moved to the bottom of the heating strip, which improves the efficiency of replacing the polytetrafluoroethylene cloth. At the same time, the used polytetrafluoroethylene cloth is wound on the active winding rod for collection, which also avoids environmental pollution caused by discarding the waste polytetrafluoroethylene cloth.

The polytetrafluoroethylene cloth 7 is adjustably arranged below the heating strip 4 through a polytetrafluoroethylene cloth adjusting device 8 arranged on the heating block body 2.

[0022] In this embodiment, the heating block body 2 is detachably arranged at the bottom of the mounting plate 1 through the pressing device 3, so as to facilitate disassembly for maintenance. The polytetrafluoroethylene cloth 7 is adjustably arranged below the heating strip 4 through the polytetrafluoroethylene cloth adjusting device 8. When the polytetrafluoroethylene cloth 7 below the heating strip 4 reaches the end of its service life, the position of the polytetrafluoroethylene cloth 7 can be adjusted through the polytetrafluoroethylene cloth adjusting device 8.

[0023] The polytetrafluoroethylene cloth adjustment device 8 includes a cavity 1 81 and a cavity 2 82, and the cavity 1 81 and the cavity 2 82 are respectively opened on the front and rear sides of the heating block body 2, and an active winding rod 83 and a driven winding rod 84 are rotatably arranged in the cavity 1 81 and the cavity 2 82 respectively, and a polytetrafluoroethylene cloth 7 is wound around the outside of the driven winding rod 84, and the outer end of the polytetrafluoroethylene cloth 7 bypasses the bottom of the heating strip 4 and is fixedly connected to the active winding rod 83. A knob 85 is arranged on the outside of the heating block body 2, and one end of the active winding rod 83 passes through the outside of the heating block body 2 and is fixedly connected to the knob 85.

When the part of the polytetrafluoroethylene cloth 7 under the heating strip 4 reaches the end of its service life, the knob 85 is turned, and the active winding rod 83 is rotated to roll the polytetrafluoroethylene cloth 7, and at the same time, the polytetrafluoroethylene cloth 7 drives the driven winding rod 84 to unwind, so that the unused part of the polytetrafluoroethylene cloth 7 moves to the bottom of the heating strip 4. The polytetrafluoroethylene cloth 7 can be set under the heating strip 4 without using tape. The position of the polytetrafluoroethylene cloth 7 can be moved by turning the knob 85, so that the unused polytetrafluoroethylene cloth 7 is moved to the bottom of the heating strip 4, thereby improving the efficiency of replacing the polytetrafluoroethylene cloth 7. At the same time, the used polytetrafluoroethylene cloth 7 is wound on the active winding rod 83 for collection, thereby avoiding environmental pollution caused by discarding the waste polytetrafluoroethylene cloth 7.

[0025] The clamping device 3 includes a fixed block 31, a slider 33 and a clamping block 34. Two sliders 33 are arranged in parallel on the top of the heating block body 2.

The clamping block 34 cooperates with the other slider 33.

[0026] In this embodiment, one of the sliders 33 is slidably disposed in the slide groove 32. When the clamping bolt 35 is tightened, the clamping block 34 approaches the mounting plate 1, and the clamping block 34 clamps the slider 33 matched therewith on both sides of the mounting plate 1 to fix it; when the clamping bolt 35 is loosened, the clamping block 34 moves away from the mounting plate 1, and the clamping block 34 and the slider 33 matched therewith are loosely matched. The slider 33 can be slid out of the slide groove 32 by moving the heating block body 2, and the mounting plate 1 and the heating block body 2 are separated. The mounting plate 1 and the heating block body 2 can be separated by slightly loosening the clamping bolt 35, which is convenient for disassembly and improves the efficiency of replacing the heating block body 2.
