[0001] This utility model relates to the technical field of bread production equipment, specifically a quick-change device for the heat-sealing blade assembly of a bread packaging machine. Background Technology
[0002] In the industrial production of baked goods, bread packaging machines are the core equipment for standardizing the packaging of various baked goods such as toast, baguettes, and dinner rolls. They complete the processes of feeding, film forming, sealing, and finished product output through automated or semi-automated procedures, providing crucial support for the preservation, storage, and transportation of bread. Among these components, the heat-sealing blade assembly, as a core functional part of the packaging machine, plays a critical role in heating and pressing the packaging film.
[0003] However, under actual production conditions, after long-term use, the heat-sealing blade assembly in bread packaging machines is prone to edge wear and surface oxidation and corrosion. Therefore, even if the machine is stopped, the blades need to be replaced and maintained. Currently, the blades in heat-sealing blade assemblies are generally fixed by bolts. Although this connection structure can ensure the stability of the blades during operation, during replacement and maintenance, operators need to use special tools to disassemble and reassemble the fixing bolts one by one. The whole process is time-consuming and laborious, thus significantly reducing the convenience of blade maintenance. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-4 As shown, this utility model is a quick-change device for the heat-sealing blade assembly of a bread packaging machine, comprising:
[0026] The tool holder 11 has two positioning rods 14 fixedly installed on its inner wall, and the outer walls of the two positioning rods 14 are engaged with the heat-sealing blade 12.
[0027] The blade holder 11 is connected to the pressure mechanism of the bread packaging machine. Two positioning holes are opened on one side of the heat-sealing blade 12, which are adapted to the positioning rod 14. The positioning rod 14 is used for connection and positioning between the heat-sealing blade 12 and the blade holder 11.
[0028] The mounting components include a fixed base 21 fixed to one side of the blade holder 11, a sliding rod 22 extending through one side of the fixed base 21, springs 24 sleeved at both ends of the outer wall of the sliding rod 22, connecting plates 25 slidably mounted on both sides of the outer wall of the sliding rod 22, a horizontal plate 26 fixedly mounted at the top of each of the two connecting plates 25, a first elastic block 27 engaging at the top of each of the two horizontal plates 26, the bottom ends of the two first elastic blocks 27 being fixedly mounted on both sides of the top of the fixed base 21, and mounting rods 28 fixedly mounted on opposite sides of each of the two connecting plates 25, with opposite ends of the two mounting rods 28 engaging and connecting with both sides of the heat-sealing blade 12.
[0029] The fixed base 21 is fixedly connected to the slide rod 22. The top of the horizontal plate 26 is provided with a first locking hole that matches the first elastic block 27. When the first elastic block 27 is engaged with the horizontal plate 26, the spring 24 is in a stretched state. When the spring 24 is in a normal state, the mounting rod 28 does not contact the heat sealing blade 12.
[0030] The mounting components also include two connecting seats 29, one side of each connecting seat 29 is fixedly mounted on both ends of one side of the tool holder 11, and the opposite sides of each connecting seat 29 are fixedly connected to both ends of the slide rod 22.
[0031] The opposite ends of the two springs 24 are fixedly connected to the opposite sides of the two connecting seats 29, and the opposite ends of the two springs 24 are fixedly connected to the two sides of the fixed seat 21.
[0032] Each of the two connecting plates 25 has a slider 210 fixedly installed on one side, and the outer walls of the two sliders 210 are slidably connected to one side of the tool holder 11 respectively.
[0033] The slider 210 is used to assist the movement limit of the connecting plate 25, so that it can move horizontally along the direction of the slide rod 22. Two slide grooves adapted to the slider 210 are opened on one side of the tool holder 11.
[0034] A second elastic block 211 is fixedly provided on the opposite side of each of the two connecting plates 25;
[0035] Working principle: When replacing or maintaining the heat-sealing blade 12, press down on the first elastic block 27. Under the elastic action of the spring 24, the two connecting plates 25 move in opposite directions until the mounting rod 28 is no longer in contact with the heat-sealing blade 12. Then move the heat-sealing blade 12 outward until it separates from the positioning rod 14. Similarly, engage the new heat-sealing blade 12 with the positioning rod 14. Then move the two connecting plates 25 in opposite directions to stretch the spring 24 until the horizontal plate 26 engages with the first elastic block 27. At this time, the mounting rod 28 is engaged with both sides of the heat-sealing blade 12. This method facilitates the disassembly and assembly of the heat-sealing blade 12. The entire disassembly and assembly process is time-saving and labor-saving, and does not require auxiliary tools, thus significantly improving the convenience of blade maintenance.
[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0037] The auxiliary fixing component includes a side cover 13, and a retaining seat 131 is fixedly provided on both sides of the side cover 13. The opposite sides of the two retaining seats 131 are respectively engaged and connected to the outer wall of the two second elastic blocks 211.
[0038] A second card hole adapted to the second elastic block 211 is provided on one side of the card holder 131.
[0039] Slides 132 are fixedly provided on both sides of the inner wall of the side cover 13, and the outer walls of the two slides 132 are slidably connected to the two sides of the tool holder 11 respectively.
[0040] The slide bar 132 is T-shaped and is used to limit the movement of the side cover 13 to prevent it from moving and separating from the knife holder 11. Both sides of the knife holder 11 are provided with limiting grooves that are adapted to the slide bar 132, and the narrow end of the slide bar 132 passes through one side of the limiting groove. When the slide bar 132 slides outward to one end of the limiting groove, the card holder 131 and the second elastic block 211 are not in contact.
[0041] Working principle: Before replacing or maintaining the heat sealing blade 12, press the two second elastic blocks 211 inward and move the side cover 13 outward. The outward movement of the side cover 13 drives the card seat 131 to move outward until the slide bar 132 slides outward to one end of the limiting groove. After disassembling and replacing the heat sealing blade, push the side cover 13 inward until the card seat 131 engages with the second elastic block 211. In this way, the heat sealing blade 12 can be assisted in limiting and fixing, which not only facilitates disassembly and assembly but also further improves the overall firmness of the heat sealing blade 12 after installation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
