Description

Technical Field

[0001] This utility model relates to the field of maintenance tool technology, and in particular to a tool for making holes in a cleaning strip. Background Technology

[0002] In tobacco leaf threshing and re-drying processing, the pneumatic conveying system is the core of material transport, and its stability directly affects processing quality and efficiency. The feeder, as a key piece of equipment in the pneumatic conveying system, is responsible for separating tobacco material from the airflow. The flap-type airlock is the core component of the feeder. On one hand, it isolates the feeder from the internal and external environments, preventing leakage of internal high-pressure airflow and the entry of external air, ensuring stable airflow and guaranteeing effective material separation. On the other hand, it transports the separated material to the next stage of equipment through rotation, supporting continuous production.

[0003] To ensure the sealing performance of the flap-type airlock, a flexible sweeping bar needs to be installed on the flap, and this bar must be in close contact with the inner wall of the feeder. Over time, the flexible sweeping bar experiences continuous friction and wear, leading to a decline in sealing performance. Therefore, it needs to be replaced periodically. Before replacement, mounting holes need to be drilled in the new sweeping bar. Current technology typically employs a two-step drilling method: punching holes first, then cutting grooves with a gate. This method is not only cumbersome and inefficient, making it difficult to meet the rapid part changeover requirements of production lines, but also makes it difficult to guarantee the consistency of the mounting hole size and groove shape during multi-step drilling. This increases the risk of uneven clearance after sweeping bar installation, potentially affecting the airlock's sealing effect and system stability. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for drilling holes in a sweeping bar, which can improve operating efficiency and the consistency of the drilling holes when drilling mounting holes in the sweeping bar.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A strip-sweeping hole-making tool is installed on a stamping machine, the stamping machine being provided with a platform, the strip-sweeping hole-making tool comprising:

[0007] A hole-opening assembly includes a hole-opening cutter, which is cylindrical and connected to the output end of the stamping equipment. The hole-opening cutter is configured to open mounting holes for a sweeping bar placed on the platform.

[0008] A material ejection assembly is movably disposed in the opening assembly corresponding to the opening cutter, and at least a portion of the material ejection assembly is inserted into the opening cutter. The material ejection assembly is configured to eject waste material from the opening cutter.

[0009] As a further technical solution, the opening assembly also includes a connecting rod and a mounting plate;

[0010] The mounting plate is fixed to the upper end of the punch cutter and cooperates with the punch cutter to form a receiving cavity for accommodating waste material. The first end of the connecting rod is connected to the mounting plate, and the second end is used for transmission connection with the output end of the stamping equipment. The mounting plate is provided with a material ejection hole that allows the material ejection assembly to be inserted.

[0011] As a further technical solution, the axis of the punch cutter is collinear with the centerline of the mounting plate and the axis of the connecting rod.

[0012] As a further technical solution, the ejector assembly includes an ejector rod, the first end of which can pass through the ejector hole and be inserted into the opening cutter.

[0013] As a further technical solution, the ejector assembly also includes an abutment plate and a compression spring. The abutment plate is sleeved on the connecting rod through a connecting hole, and the compression spring is sleeved on the connecting rod. The two ends of the compression spring are respectively connected to the mounting plate and the abutment plate, and the second end of the ejector rod is connected to the abutment plate.

[0014] As a further technical solution, the ejector assembly also includes an ejector plate, which is disposed inside the perforated cutter and fixed to the first end of the ejector rod.

[0015] As a further technical solution, the ejector assembly also includes an adjusting nut, the second end of the ejector rod is provided with an external thread, the abutment plate is provided with an adjusting hole that allows the ejector rod to pass through, and the adjusting nut is screwed to the second end of the ejector rod.

[0016] As a further technical solution, two ejector rods are provided, and two adjustment holes are correspondingly provided on the abutment plate. The two adjustment holes are symmetrically arranged about the center line of the ejector rods, and two ejector holes are correspondingly provided.

[0017] As a further technical solution, the unloading assembly also includes an auxiliary sleeve, which is sleeved on the connecting rod, and the abutment plate is fixed to the lower end of the auxiliary sleeve.

[0018] As a further technical solution, the unloading assembly also includes an auxiliary plate, which is sleeved on the connecting rod through an auxiliary hole and fixed to the upper end of the auxiliary sleeve.

[0019] Compared with the prior art, the scanning and drilling tool provided in this embodiment has the following technical advantages:

[0020] 1. Because the punch cutter is cylindrical and connected to the output end of the stamping equipment, when it is necessary to punch mounting holes for the sweeping bar, simply connect the punch cutter to the output end of the stamping equipment and start the stamping equipment to move the punch cutter towards the placement platform. The entire process requires only one punch to complete the punching of the mounting hole, making the process simple and convenient, improving operational efficiency. Moreover, since sweeping bars from the same batch are punched using the same punch cutter, the size and groove shape of the mounting holes are consistent, thereby reducing the risk of uneven clearance after the sweeping bars are installed in the flap-type airlock, ensuring the sealing effect and system stability of the flap-type airlock.

[0021] 2. Since at least part of the ejector assembly is inserted into the hole-opening cutter, during the process of opening mounting holes, after the cut-off waste material is embedded in the cylindrical hole-opening cutter, the ejector assembly is pushed to push the waste material embedded in the hole-opening cutter out, facilitating the next batch of mounting hole opening operations. Throughout the process, the ejector assembly helps to push out the waste material, further improving operational convenience and overall efficiency when opening mounting holes.

[0030] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0031] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0032] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0035] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0036] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element.

For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0037] Combination Figures 1 to 3 As shown, the sweeping bar hole-making tool provided in this embodiment is installed on the stamping equipment 10. The stamping equipment 10 is provided with a placement platform 11. When the sweeping bar hole-making tool makes mounting holes for the sweeping bar, it can improve the operating efficiency and the consistency of the mounting holes. Specifically, the sweeping bar hole-making tool includes a hole-making assembly 100 and a material ejection assembly 200. The hole-making assembly 100 includes a hole-making cutter 110, which is cylindrical and connected to the output end of the stamping equipment 10. The hole-making cutter 110 is configured to make mounting holes for the sweeping bar placed on the placement platform 11. The material ejection assembly 200 is movably disposed in the hole-making assembly 100 corresponding to the hole-making cutter 110, and at least part of the material ejection assembly 200 is inserted into the hole-making cutter 110. The material ejection assembly 200 is configured to eject the waste material inside the hole-making cutter 110.

[0038] The lower end of the perforating cutter 110 serves as the cutting edge. Since the perforating cutter 110 is cylindrical and connected to the output end of the stamping equipment 10, when it is necessary to create mounting holes for the sweeping bar, the perforating cutter 110 is connected to the output end of the stamping equipment 10, and the stamping equipment 10 is started, causing the perforating cutter 110 to move towards the placement platform 11. The entire process requires only one stamping operation to complete the opening of the mounting hole. The entire process is simple and convenient, not only improving operational efficiency, but also ensuring consistency in the size and groove shape of the mounting holes since sweeping bars from the same batch are opened using the same perforating cutter 110. This reduces the risk of uneven clearance after the sweeping bars are installed in the flap-type airlock, ensuring the sealing effect and system stability of the flap-type airlock.

[0039] Since at least part of the ejector assembly 200 is inserted into the hole-opening cutter 110, during the process of opening mounting holes, after the cut-off waste material is embedded in the cylindrical hole-opening cutter 110, the ejector assembly 200 is pushed to push the waste material embedded in the hole-opening cutter 110 out of the cutter 110, so as to facilitate the next batch of mounting hole opening operations. Throughout the process, the ejector assembly 200 pushes out the waste material, further improving operational convenience and overall efficiency when opening mounting holes.

[0040] To further improve the consistency of the opening, a limiting position area can be set on the placement platform 11 corresponding to the output end of the stamping equipment 10. When opening the hole, the sweeping bar is placed in the limiting position area to limit the relative position of the sweeping bar, thereby ensuring the consistency of the relative position of the mounting holes on the sweeping bar and further reducing the risk of uneven fit clearance after the sweeping bar is installed on the flip-type air lock.

[0041] The stamping equipment 10 can be adapted to be a manual stamping equipment 10, a semi-automatic stamping equipment 10, or a fully automatic stamping equipment 10 according to actual needs. This embodiment does not make specific limitations. In addition, the specific structure of the stamping equipment 10 is not the focus of this embodiment. It can be set with reference to the existing technology and will not be described in detail here.

[0042] To improve the ease of connection and stability of the perforation cutter 110 to the output end of the stamping equipment 10, in this embodiment, the perforation assembly 100 further includes a connecting rod 120 and a mounting plate 130. The mounting plate 130 is fixed to the upper end of the perforation cutter 110 and cooperates with the perforation cutter 110 to form a receiving cavity for accommodating waste material. The first end of the connecting rod 120 is connected to the mounting plate 130, and the second end is used for transmission connection with the output end of the stamping equipment 10. The mounting plate 130 is provided with a discharge hole that allows the discharge assembly 200 to be inserted. By setting the connecting rod 120, the ease of connection between the perforation cutter 110 and the output end of the stamping equipment 10 is improved, and interference between the perforation cutter 110 and the output end of the stamping equipment 10 is avoided. By setting the mounting plate 130, the connection strength and stability between the perforation cutter 110 and the connecting rod 120 are improved.

[0043] To further enhance the connection strength and stability between the hole cutter 110 and the connecting rod 120, in this embodiment, the axis of the hole cutter 110 is collinear with the centerline of the mounting plate 130 and the axis of the connecting rod 120. During long-term use of the hole-making assembly 100, this avoids situations where the hole cutter 110 and the connecting rod 120 are eccentrically positioned, leading to uneven stress on the hole cutter 110 during the hole-making process, resulting in poor hole-making effect and efficiency. Simultaneously, it avoids situations where uneven stress causes the connecting rod 120 to break or gaps to appear at the connection between the connecting rod 120 and the mounting plate 130.

[0044] Preferably, the unloading assembly 200 includes an unloading rod 210, the first end of which can pass through the unloading hole and be inserted into the perforated cutter 110. When it is necessary to eject the waste material accumulated in the receiving cavity, the first end of the unloading rod 210 is inserted into the unloading hole, and the unloading rod 210 is pushed downward. Furthermore, since the unloading hole is located on the mounting plate 130, the convenience and efficiency of ejecting waste material are maximized.

[0045] In addition, the volume of the receiving cavity can be increased by increasing the length of the opening cutter 110, so that the receiving cavity can hold more waste at one time, thereby reducing the frequency of waste ejection and further improving the overall efficiency.

[0046] Furthermore, the ejector assembly 200 also includes an abutment plate 220 and a compression spring 230. The abutment plate 220 is sleeved on the connecting rod 120 through a connecting hole, and the compression spring 230 is sleeved on the connecting rod 120. The two ends of the compression spring 230 are respectively connected to the mounting plate 130 and the abutment plate 220. The second end of the ejector rod 210 is connected to the abutment plate 220.

[0047] In the initial state, the first end of the ejector rod 210 is inserted into the ejector hole, but the first end of the ejector rod 210 does not extend into the hole cutter 110.

[0048] By setting up the abutment plate 220 and the compression spring 230, when the output end of the stamping equipment 10 drives the punching cutter 110 to move upward, the abutment plate 220 abuts against the base of the stamping equipment 10. As the punching cutter 110 continues to move upward, the abutment plate 220 and the ejector rod 210 move downward relative to the punching cutter 110. During this process, the waste material inside the punching cutter 110 is pushed out of the punching cutter 110, thereby further improving the waste material ejection efficiency. In addition, during the process of pushing the waste material out of the punching cutter 110, the compression spring 230 is compressed. After the waste material is pushed out of the punch cutter 110, the output end of the stamping equipment 10 drives the punch cutter 110 to move downward. As the punch cutter 110 continues to move downward, the compression spring 230 is no longer under the pressure and begins to rebound on its own. During the rebound of the compression spring 230, it pushes the abutment plate 220 to move upward, thereby driving the ejector rod 210 to move upward, so as to reduce the insertion amount of the ejector rod 210 in the punch cutter 110. During the subsequent hole opening process, the ejector rod 210 is prevented from interfering with the waste material in the accommodating cavity, ensuring that the accommodating cavity can accommodate more waste material.

[0049] Preferably, the unloading assembly 200 further includes an unloading plate 240, which is disposed inside the perforated cutter 110 and fixed to the first end of the unloading rod 210.

[0050] In this embodiment, the cross-sectional shape of the ejector plate 240 is consistent with the cross-sectional shape of the perforating cutter 110 in its axial direction. When ejecting waste, the thrust on the waste is made as equal as possible in the axial direction of the perforating cutter 110, thereby improving the convenience of ejecting the waste. The cross-sectional area of ​​the ejector plate 240 is slightly smaller than the cross-sectional area of ​​the perforating cutter 110 in its axial direction. That is, there is a clearance between the side wall of the ejector plate 240 and the inner wall of the perforating cutter 110 that is always equal. During the ejection of waste or the compression spring 230 driving the ejector rod 210 and the ejector plate 240 to return to their original state, the ejector plate 240 is prevented from getting stuck in the perforating cutter 110. Meanwhile, as the compression spring 230 rebounds autonomously, pushing the abutment plate 220 upward to drive the ejector bar 210 upward, the ejector plate 240 can prevent the ejector bar 210 from completely disengaging from the opening cutter 110, thereby further improving the ease of operation when ejecting waste material.

[0051] In this embodiment, the piercing cutter 110 has a long, narrow cross-sectional shape in its axial direction. In other embodiments, the cross-sectional shape of the piercing cutter 110 in its axial direction can be adapted to actual needs and is not limited to this embodiment.

[0052] Preferably, the ejector assembly 200 further includes an adjusting nut 250. The second end of the ejector rod 210 is provided with an external thread, and the abutment plate 220 is provided with an adjusting hole that allows the ejector rod 210 to pass through. The adjusting nut 250 is screwed to the second end of the ejector rod 210. With this configuration, the relative position of the adjusting nut 250 and the second end of the ejector rod 210 can be adjusted by turning the adjusting nut 250, thereby appropriately adjusting the force of the compression spring 230. After the waste material is ejected, it is ensured that the ejector rod 210, the abutment plate 220, and the ejector plate 240 can always return to their initial state.

[0053] After the position adjustment is completed, in order to further improve the relative positional stability between the adjusting nut 250 and the ejector rod 210, in this embodiment, two adjusting nuts 250 are provided at the second end of the ejector rod 210. The two adjusting nuts 250 are located on the upper and lower sides of the abutment plate 220 respectively, and both abut against the abutment plate 220.

[0054] To further improve the convenience of ejecting waste material and the smoothness of the ejector plate 240's movement, in this embodiment, two ejector rods 210 are provided, and two corresponding adjustment holes are provided on the abutment plate 220. The two adjustment holes are symmetrically arranged about the centerline of the ejector rods 210, and two ejector holes are provided accordingly. This ensures that the thrust on opposite sides of the ejector plate 240 is equal, further reducing the risk of the ejector plate 240 getting stuck in the perforated cutter 110.

[0055] Furthermore, the unloading assembly 200 also includes an auxiliary sleeve 260, which is sleeved on the connecting rod 120, and the abutment plate 220 is fixed to the lower end of the auxiliary sleeve 260. By setting the auxiliary sleeve 260, on the one hand, the moving path of the punching cutter 110 in the vertical direction is extended, so that mounting holes can be made for sweeping bars of different thicknesses, thereby improving the applicability of the sweeping bar punching tool; on the other hand, when the waste material is pushed out of the punching cutter 110, interference between the adjusting nut 250 and the base of the stamping equipment 10 is avoided.

[0056] Furthermore, the unloading assembly 200 also includes an auxiliary plate 270. The auxiliary plate 270 is sleeved on the connecting rod 120 through an auxiliary hole and fixed to the upper end of the auxiliary sleeve 260. By setting the auxiliary plate 270, the contact area between the unloading assembly 200 and the base of the stamping equipment 10 is increased. This not only ensures the scrap ejection effect but also reduces the probability of mechanical damage caused by the auxiliary plate 270 and the base of the stamping equipment 10 coming into contact with each other, thus extending the service life of the unloading assembly 200.

[0057] 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.
