Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology, and in particular to a positioning plate disassembly tooling. Background Technology

[0002] like Figure 1 As shown, in the inner liner paper conveying system of the packaging machine, the inner liner paper is cut into individual sheets by a cutting knife and then transported by suction through negative pressure suction holes distributed on the surface of the suction roller 100. However, the suction roller 100 is prone to clogging during long-term use, requiring regular cleaning and unblocking of the negative pressure suction holes. During cleaning and unblocking, the connecting plate 200 and the positioning plate 300 must be disassembled first, followed by the suction roller 100. Because the positioning plate 300 has an interference fit with the suction roller shaft and the cutting knife shaft 500, this fit makes the disassembly of the positioning plate 300 extremely challenging.

[0003] Currently, when disassembling the positioning plate, operators typically use simple tools such as flathead screwdrivers and rubber mallets to remove it by prying or knocking. This method is not only labor-intensive and inefficient, but also, due to the tightness of the interference fit, forced disassembly can easily cause mechanical damage to the positioning plate, adsorption roller shaft, or cutting blade shaft, increasing equipment maintenance costs and downtime.

[0004] Therefore, there is an urgent need to propose a positioning plate disassembly tool to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning plate disassembly fixture, which reduces the difficulty of disassembling the positioning plate, reduces the risk of mechanical damage to the positioning plate, adsorption roller shaft or cutting knife shaft, improves disassembly efficiency, reduces equipment maintenance costs and downtime, and improves the overall operating efficiency of the equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A positioning plate disassembly fixture is provided, wherein the positioning plate is provided with at least two bearings, which are respectively interference-fitted with the cutting blade shaft and the adsorption roller shaft. The positioning plate disassembly fixture includes a fixture body and at least two abutting members. The fixture body is detachably connected to the positioning plate. The fixture body has a first threaded hole corresponding to the cutting blade shaft and the adsorption roller shaft. The abutting members are threadedly connected to the first threaded holes, and the first end of the abutting member can abut against the cutting blade shaft or the adsorption roller shaft.

[0008] In some alternative embodiments, the bearing portion protrudes from the surface of the positioning plate, and the tooling body has a clearance groove on the side facing the positioning plate to avoid the bearing.

[0009] In some optional embodiments, the positioning plate has an adjusting stud protruding from its surface, and the tooling body also has a through hole for avoiding the adjusting stud.

[0010] In some optional embodiments, the second end of the abutment is provided with a snap-fit ​​portion, and the positioning plate disassembly fixture further includes a screw handle that can engage with the snap-fit ​​portion.

[0011] In some alternative embodiments, the second end of the abutment has a hexagonal hole, and the screw handle includes an internal hex wrench adapted to the type of the hexagonal hole.

[0012] In some optional embodiments, the abutting member includes a connecting portion and an abutting top connected together. The connecting portion has external threads machined on its circumferential surface. The diameter of the abutting top is larger than the diameter of the connecting portion and smaller than the inner diameter of the corresponding bearing, and is used to abut against the cutting blade shaft or the adsorption roller shaft.

[0013] In some alternative embodiments, the height of the abutment is greater than the height of the corresponding bearing.

[0014] In some alternative embodiments, the tooling body is threadedly connected to the positioning plate.

[0015] In some optional embodiments, the positioning plate has a plurality of second threaded holes, the tooling body has a third threaded hole corresponding to each of the second threaded holes, and the positioning plate disassembly tooling also includes a plurality of connectors for threaded connection with the second threaded holes and the third threaded holes.

[0016] In some alternative embodiments, the tooling body is snapped into the positioning plate.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a positioning plate disassembly fixture. The positioning plate is provided with at least two bearings, which are respectively interference-fitted with the cutting blade shaft and the adsorption roller shaft. The positioning plate disassembly fixture is used to assist in separating the positioning plate from the cutting blade shaft and the adsorption roller shaft. The positioning plate disassembly fixture includes a fixture body and at least two abutting members. The fixture body is detachably connected to the positioning plate. The fixture body has first threaded holes corresponding one-to-one with the cutting blade shaft and the adsorption roller shaft. The abutting members are threadedly connected to the first threaded holes, and the first end of the abutting member can abut against the cutting blade shaft or the adsorption roller shaft. When the adsorption roller needs maintenance, firstly, the fixture body is connected to the positioning plate, so that the two abutting members are respectively aligned with the cutting blade shaft and the adsorption roller shaft. Then, the abutting members are screwed on, causing them to move axially towards the cutting blade shaft or the adsorption roller shaft. Using the force exerted by the abutting members on the cutting blade shaft or the adsorption roller shaft, the positioning plate is smoothly separated from the cutting blade shaft and the adsorption roller shaft. By using a positioning plate disassembly fixture to separate the positioning plate from the cutting blade shaft and the adsorption roller shaft, the difficulty of disassembling the positioning plate is reduced, the risk of mechanical damage to the positioning plate, adsorption roller shaft, or cutting blade shaft is reduced, and the disassembly efficiency is improved. This reduces equipment maintenance costs and downtime, and improves the overall operating efficiency of the equipment. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1-5 As shown, this embodiment provides a positioning plate disassembly fixture. The positioning plate 300 is provided with at least two bearings 600, which are respectively interference-fitted with the cutting blade shaft 500 and the adsorption roller shaft 400. The positioning plate disassembly fixture is used to assist the positioning plate 300 in separating from the cutting blade shaft 500 and the adsorption roller shaft 400.

[0032] The positioning plate disassembly fixture includes a fixture body 1 and at least two abutting parts 2. The fixture body 1 is detachably connected to the positioning plate 300. The fixture body 1 has a first threaded hole 11 that corresponds one-to-one with the cutting blade shaft 500 and the adsorption roller shaft 400. The abutting parts 2 are threadedly connected to the first threaded holes 11, and the first end of the abutting parts 2 can abut against the cutting blade shaft 500 or the adsorption roller shaft 400.

[0033] When the adsorption roller 100 needs to be repaired, first connect the tool body 1 to the positioning plate 300 so that the two abutting parts 2 are directly opposite the cutting blade shaft 500 and the adsorption roller shaft 400 respectively. Then, screw the abutting parts 2 so that the abutting parts 2 move axially towards the cutting blade shaft 500 or the adsorption roller shaft 400. Using the force of the abutting parts 2 on the cutting blade shaft 500 or the adsorption roller shaft 400, the positioning plate 300 is smoothly separated from the cutting blade shaft 500 and the adsorption roller shaft 400.

[0034] By using a positioning plate disassembly fixture to separate the positioning plate 300 from the cutting blade shaft 500 and the adsorption roller shaft 400, the difficulty of disassembling the positioning plate 300 is reduced, the risk of mechanical damage to the positioning plate 300, adsorption roller shaft 400 or cutting blade shaft 500 is reduced, and the disassembly efficiency is improved. This reduces equipment maintenance costs and downtime, and improves the overall operating efficiency of the equipment.

[0035] like Figure 3 and Figure 4 As shown, in some optional embodiments, since the bearing 600 protrudes from the surface of the positioning plate 300, the tooling body 1 facing the positioning plate 300 is also provided with a relief groove 12 for avoiding the bearing 600, so as to improve the fit between the tooling body 1 and the positioning plate 300, thereby improving the force balance of the positioning plate 300, improving the disassembly stability, effectively reducing the possibility of mechanical damage to components such as the positioning plate 300, the adsorption roller shaft 400 and the cutting knife shaft 500 caused by local stress concentration, and protecting the integrity of the equipment.

[0036] In some optional embodiments, the positioning plate 300 has an adjusting stud 700 protruding on its surface, and the tooling body 1 also has a through hole 13 for avoiding the adjusting stud 700, thereby avoiding interference between the connecting plate 200 and the adjusting stud 700 and ensuring that the tooling body 1 fits snugly with the positioning plate 300.

[0037] like Figure 5 As shown, in some optional embodiments, the second end of the abutment 2 is provided with a snap-fit ​​part, and the positioning plate disassembly tool also includes a screw handle, which can be snapped with the snap-fit ​​part to facilitate screwing the abutment 2.

[0038] In this embodiment, the second end of the abutment 2 has a hexagonal hole 21, forming the aforementioned snap-fit ​​portion. The screw handle includes an internal hex wrench that is compatible with the hexagonal hole 21. The internal hex wrench is a general-purpose standard part, readily available, requiring no custom-made special tools, and can be quickly replaced, avoiding disassembly delays and shortening maintenance preparation time. Furthermore, the hexagonal hole 21 has a simple structure and low processing cost, which helps reduce the overall cost of tooling and makes it highly practical.

[0039] Of course, in other embodiments, the second end of the abutment 2 may also have a cross groove, and the positioning plate disassembly tool includes a cross screwdriver that is compatible with the cross groove model, which is not limited here.

[0040] In some optional embodiments, the abutting member 2 includes a connecting part 22 and an abutting top 23 connected together. The connecting part 22 has external threads machined on its circumferential surface for threaded connection with the first threaded hole 11. The diameter of the abutting top 23 is larger than the diameter of the connecting part 22 and smaller than the inner diameter of the corresponding bearing 600, and is used to abut against the cutting blade shaft 500 or the adsorption roller shaft 400.

[0041] The diameter of the abutment 23 is larger than that of the connecting part 22, which increases the contact area between the abutment 2 and the shaft. This helps to improve the balance of force on the cutting blade shaft 500 or the adsorption roller shaft 400, and reduces the possibility of mechanical damage to components such as the adsorption roller shaft 400 and the cutting blade shaft 500 due to local stress concentration. Conversely, the diameter of the abutment 23 is smaller than the inner diameter of the corresponding bearing 600, which avoids interference between the abutment 23 and the bearing 600, ensuring the stability and continuity of the disassembly process and preventing damage to the bearing 600.

[0042] like Figure 2 As shown, in some optional embodiments, the height of the abutment 2 is greater than the height of the corresponding bearing 600. By screwing the abutment 2, the cutting blade shaft 500 or the adsorption roller shaft 400 can be completely pushed away from the corresponding bearing 600. This avoids the situation where the shaft and bearing 600 are still partially connected due to the insufficient height of the abutment 2, and prevents secondary friction from occurring during movement or processing due to the shaft and bearing 600 not being completely separated. This further protects the precision of the components and helps to ensure the efficiency and reliability of the disassembly operation.

[0043] In some optional embodiments, the tooling body 1 is threadedly connected to the positioning plate 300, and the connection between the two is stable and easy to install and disassemble.

[0044] like Figures 2-4As shown, specifically, the positioning plate 300 has multiple second threaded holes, and the tooling body 1 has third threaded holes 14 corresponding to the second threaded holes one by one. The positioning plate disassembly tooling also includes multiple connectors 3 for threaded connection with the second threaded holes and the third threaded holes 14. By using multiple connectors 3 to stably connect the tooling body 1 and the positioning plate 300, the fit and connection stability of the two can be improved, ensuring that the positioning plate 300 is subjected to balanced force.

[0045] Among them, the connecting component 3 includes, but is not limited to, screws or bolts, which are not limited here.

[0046] In other embodiments, the tooling body 1 is snapped into the positioning plate 300. By setting a snap block on the tooling body 1 and opening a snap slot in the positioning plate 300 that can snap into the snap block, the tooling body 1 and the positioning plate 300 can also be fixedly connected. This is not limited here.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
