Inspection auxiliary tooling and packaging machine

Abstract

This utility model belongs to the field of cigarette manufacturing technology and discloses a testing auxiliary fixture and a packaging machine. The testing auxiliary fixture includes a base, a spring, and a pressing component. The spring is connected to the base and has a splicing edge area and a contact area. The contact area can be raised relative to the base under its own elastic force and is used to abut against the object to be tested. The pressing component is connected to the base and presses against the edge area of ​​the spring on the side away from the base. The packaging machine includes the above-mentioned testing auxiliary fixture. Because the pressing component on the testing auxiliary fixture presses against the spring, it can prevent the edge area of ​​the spring from rubbing against the drying drum after being raised due to its own elastic force, avoiding damage to the spring due to poor contact between the spring and the drying drum. This reduces the number of downtimes caused by testing auxiliary fixture malfunctions and improves the overall working efficiency of the packaging machine.

Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a testing auxiliary tooling and packaging machine. Background Technology

[0002] In the cigarette manufacturing process, packaging machines are used to pack cigarette packs. These machines are equipped with detection devices. When a cigarette pack moves to the detection device and presses against a metal spring on the device, the spring deforms and is detected by a distance sensor, which then sends a signal. When the cigarette pack leaves the detection device, the metal spring returns to its original shape due to its elasticity, and the distance sensor stops sending signals, thus indicating whether the cigarette pack has reached the designated position. However, in existing detection devices, the edge of the metal spring scrapes against the drying drum when it springs back up. When the drying drum is running, this poor contact can easily damage the metal spring, rendering the detection device unable to perform its detection function.

[0003] Therefore, there is an urgent need to design a testing fixture and packaging machine to solve the above-mentioned problems in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tooling and packaging machine for testing, which can prevent damage to the spring sheet caused by poor contact between the edge area of ​​the spring sheet and the drying drum.

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

[0006] Inspection auxiliary tooling, including:

[0007] Base;

[0008] A spring sheet is connected to the base. The spring sheet has a spliced ​​edge area and an abutment area. The abutment area can be raised relative to the base under its own elastic force. The abutment area is used to abut against the object to be tested.

[0009] A pressing member is connected to the base and presses against the edge region of the spring sheet on the side opposite to the base.

[0010] Preferably, the edge region includes a first edge region and a second edge region disposed opposite to each other, and the pressing member includes a first pressing part and a second pressing part, wherein the first pressing part presses against the first edge region and the second pressing part presses against the second edge region.

[0011] Preferably, the pressing member further includes a connecting portion, one end of which is connected to the first pressing portion, and the other end of which is connected to the second pressing portion.

[0012] Preferably, the abutting area includes a first abutting area and a second abutting area disposed opposite to each other, and the pressing member has a hollowed-out first detection area and a second detection area, the first detection area being disposed opposite to the first abutting area and the second detection area being disposed opposite to the second abutting area.

[0013] Preferably, the base has a clearance slot, which is positioned directly opposite the contact area.

[0014] Preferably, the spring sheet has a first connecting hole, the base has a first threaded hole, and a first connector passing through the first connecting hole and the first threaded hole fixes the spring sheet and the base.

[0015] Preferably, the pressing member has a second connecting hole, the base has a second threaded hole, and a second connecting member passing through the second connecting hole and the second threaded hole fixes the pressing member and the base.

[0016] Preferably, the first connecting hole and the second connecting hole are positioned opposite each other, and the first threaded hole and the second threaded hole overlap.

[0017] Preferably, the abutting area includes a first abutting area and a second abutting area that are positioned opposite each other, and the first connecting hole is formed between the first abutting area and the second abutting area.

[0018] The packaging machine includes a distance sensor, a drying drum, and the aforementioned detection auxiliary fixture. The distance sensor is positioned facing the contact area, and the detection auxiliary fixture is positioned facing the inlet of the drying drum.

[0019] The beneficial effects of this utility model are as follows:

[0020] The detection auxiliary tooling provided by this utility model includes a base, a spring, and a pressing component. The spring has an edge area and a contact area. Since the contact area of ​​the spring can be raised off the base under its own elastic force, and the contact area is used to abut against the object to be tested, when the object to be tested is delivered to the position, the contact area is pressed close to the base. When the object to be tested leaves, the contact area will be raised under the elastic force. Therefore, the distance sensor can determine whether the object to be tested has been delivered to the position by detecting whether the contact area is raised. Since the pressing component is connected to the base and presses against the edge area of ​​the spring, when the contact area is raised under its own elastic force, the edge area is not affected by the elastic force and always stays close to the base, thereby avoiding the edge area from scraping against the drying drum due to the raised edge area, and preventing the spring from being damaged due to poor contact between the edge area and the drying drum.

[0021] The packaging machine provided by this utility model includes a distance sensor, a drying drum, and the aforementioned detection auxiliary fixture. The detection auxiliary fixture is positioned directly opposite the drying drum. Since the pressing component on the detection auxiliary fixture presses against the spring sheet, it can prevent the edge area of ​​the spring sheet from lifting up due to its own elasticity and rubbing against the drying drum. This avoids damage to the spring sheet caused by poor contact between the spring sheet and the drying drum, thereby reducing the number of downtimes caused by malfunctions of the detection auxiliary fixture and improving the overall working efficiency of the packaging machine.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," and "left," 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.

[0033] like Figure 1 and Figure 2 As shown, this utility model provides a detection auxiliary tooling, which includes a base 1, a spring 2, and a pressing member 3. The spring 2 is connected to the base 1 and has a spliced ​​edge area and a pressing area 21. The pressing area 21 can be raised relative to the base 1 under its own elastic force and is used to abut against the object to be tested. The pressing member 3 is connected to the base 1 and presses against the edge area of ​​the spring 2 on the side away from the base 1. In this embodiment, since the contact area 21 of the spring piece 2 can be raised on the base 1 under its own elastic force, and the contact area 21 is used to abut against the object to be tested, when the object to be tested is delivered to the position, the contact area 21 is pressed close to the base 1. When the object to be tested leaves, the contact area 21 will be raised under the elastic force. Therefore, the distance sensor can determine whether the object to be tested has been delivered to the position by detecting whether the contact area 21 is raised. Since the base 1 is connected to the pressing member 3, the pressing member 3 presses against the edge area of ​​the spring piece 2. Therefore, when the contact area 21 is raised under its own elastic force, the edge area is not affected by the elastic force and always stays close to the base 1, thereby avoiding the edge area from scraping against the drying drum due to the raised area, and preventing the spring piece 2 from being damaged due to poor contact between the edge area and the drying drum.

[0034] Specifically, the spring 2 is a rectangular metal sheet. The spring 2 is fixed to the base 1 by the pressing member 3. The contact area 21 of the spring 2 is raised away from the base 1. When the object to be tested is transported to the designated position, the object to be tested abuts against the contact area 21. The contact area 21 is then compressed and undergoes elastic deformation in the direction closer to the base 1. The distance sensor can detect the position of the contact area 21 and send a signal to the outside to indicate that the object to be tested has been transported to the designated position.

[0035] like Figure 1 As shown, the edge region includes a first edge region and a second edge region arranged opposite to each other. The pressing member 3 includes a first pressing part 31 and a second pressing part 32. The first pressing part 31 presses against the first edge region, and the second pressing part 32 presses against the second edge region. Specifically, the spring piece 2 is a rectangular metal sheet with a certain elasticity. The two opposite ends of the spring piece 2 are the first edge region and the second edge region, respectively. The other two ends of the spring piece 2 and the area located between the first edge region and the second edge region are the abutment region 21. Correspondingly, the pressing member 3 has a first pressing part 31 and a second pressing part 32 arranged opposite to each other. The first pressing part 31 and the second pressing part 32 can be a separate structure or a connected structure.

[0036] For ease of disassembly, assembly, and subsequent maintenance, such as Figure 1 As shown, the pressing member 3 also includes a connecting part 33, one end of which is connected to the first pressing part 31, and the other end of which is connected to the second pressing part 32. Specifically, the pressing member 3 has an H-shaped structure, with the first pressing part 31 and the second pressing part 32 on both sides pressing against the first edge area and the second edge area respectively, thereby pressing the edge area of ​​the spring piece 2 against the base 1, and the position on the spring piece 2 between the first pressing part 31 and the second pressing part 32 is the abutting area 21.

[0037] like Figure 1 and Figure 2 As shown, the abutment area 21 includes a first abutment area 211 and a second abutment area 212 arranged opposite to each other. The pressing member 3 has a hollowed-out first detection area 34 and a second detection area 35. The first detection area 34 is positioned directly opposite the first abutment area 211, and the second detection area 35 is positioned directly opposite the second abutment area 212. Specifically, the spring piece 2 is a rectangular metal sheet, with the first abutment area 211 and the second abutment area 212 at opposite ends. The pressing member 3 has an H-shaped structure, with the first pressing portion 31 and the second pressing portion 32 on both sides of the pressing member 3 pressing against the first edge area and the second edge area, respectively. The first detection area 34 and the second detection area 35 on the pressing member 3 are positioned directly opposite the first abutment area 211 and the second abutment area 212, respectively. The first abutment area 211 and the second abutment area 212 of the spring piece 2 can be raised outwards through the first detection area 34 and the second detection area 35, respectively. Further, as Figure 2As shown, the base 1 has a clearance slot 11, which is positioned directly opposite the abutment area 21. Specifically, the cross-section of the base 1 is an H-shaped structure identical to that of the pressing member 3. The base 1 has two opposing clearance slots 11, which are respectively opened for the first abutment area 211 and the second abutment area 212, in order to provide the abutment area 21 with greater rebound space and at the same time reduce the weight of the base 1.

[0038] The connection method between the spring 2 and the base 1 can be set according to the actual situation, as long as it ensures a stable connection and facilitates later maintenance. For example, such as Figure 2 As shown, the spring 2 has a first connecting hole 22 and the base 1 has a first threaded hole. The first connecting piece 4, which passes through the first connecting hole 22 and the first threaded hole, fixes the spring 2 and the base 1. Specifically, the first connecting piece 4 is a bolt or screw.

[0039] The connection method between the pressing component 3 and the base 1 can also be set according to the actual situation, as long as it can ensure a stable connection between the two and facilitate future maintenance. For example, such as Figure 2 As shown, the pressing member 3 has a second connecting hole 36, and the base 1 has a second threaded hole. A second connecting member passing through the second connecting hole 36 and the second threaded hole fixes the pressing member 3 and the base 1. Specifically, the second connecting member is a bolt or screw.

[0040] For ease of disassembly, assembly, and subsequent maintenance, such as Figure 1 and Figure 2 As shown, the first connecting hole 22 and the second connecting hole 36 are arranged opposite each other, and the first threaded hole and the second threaded hole coincide. Specifically, the base 1 has two first threaded holes, the spring 2 has two first connecting holes 22, and the pressing member 3 has two second connecting holes 36. When assembling this testing auxiliary tooling, the workers place the base 1, the spring 2 and the pressing member 3 in sequence, align the first connecting holes 22 and the second connecting holes 36, and then pass the bolts through the pressing member 3 and the spring 2 in sequence and screw them into the first threaded holes.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the abutting area 21 includes a first abutting area 211 and a second abutting area 212 facing each other, and a first connecting hole 22 is formed between the first abutting area 211 and the second abutting area 212. It can be understood that the spring piece 2 is a rectangular piece, the first abutting area 211 and the second abutting area 212 are opposite ends on the spring piece 2, and the first connecting hole 22 is formed in the middle position of the first abutting area 211 and the second abutting area 212, thereby ensuring that both the first abutting area 211 and the second abutting area 212 can be freely raised. In contrast, the second connecting hole 36 is formed in the connecting part 33 of the pressing member 3.

[0042] To further improve the fixing effect of the pressing member 3 on the spring piece 2, bolts are also connected to the first pressing part 31 and / or the second pressing part 32 of the pressing member 3, so as to more firmly press the edge area of ​​the spring piece 2.

[0043] This embodiment also provides a packaging machine, which includes a distance sensor, a drying drum, and the aforementioned detection auxiliary fixture. The distance sensor is positioned directly opposite the contact area 21, and the detection auxiliary fixture is positioned directly opposite the inlet of the drying drum. In this embodiment, since the pressing member 3 on the detection auxiliary fixture presses against the spring 2, it can prevent the edge area of ​​the spring 2 from lifting up due to its own elasticity and scraping against the drying drum. This avoids damage to the spring 2 caused by poor contact between the spring 2 and the drying drum, thereby reducing the number of downtimes caused by malfunctions of the detection auxiliary fixture and improving the overall working efficiency of the packaging machine.

[0044] 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.
