Description

Technical Field

[0001] This utility model relates to the field of tobacco safety protection technology, and in particular to a folding guardrail and a rolling machine. Background Technology

[0002] In the tobacco production industry, the cigarette making machine is one of the core production equipment, and its stable operation is crucial to ensuring the production efficiency and quality of tobacco products. With the expansion of production scale and the increase in production intensity, the cigarette making machine needs to be cleaned and maintained regularly, and during operation, high-level failures inevitably occur, requiring repair.

[0003] Under the current operating model, when cleaning, maintenance, or troubleshooting is required on the higher parts of the winding and splicing machine (such as the top), operators must use a mobile ladder to access the work area. However, this method poses a serious safety hazard. Since the top of the equipment is 2000mm above the ground, without effective protective measures, operators working at height are highly susceptible to slipping, loss of balance, or other accidents that could lead to falls and serious personal injury. This not only causes irreparable damage to the operator's life and health but also results in significant economic losses for the company, including medical expenses, workers' compensation, and production stoppages.

[0004] Existing coiling machines are generally equipped with protective devices to ensure the safety of workers, but these devices are typically quite large. For equipment like coiling machines that require frequent operation of different types of tasks (including daily production operations, regular maintenance, and troubleshooting), when the protective devices are not needed, the large space they occupy can obstruct normal operation and passage around the equipment, thus failing to meet the requirements for efficient and convenient operation. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing protective equipment occupies a large amount of space when not in use, thus affecting normal operation and passage. This invention provides a folding guardrail and a rolling machine, which can protect operators when in use and is easy to store when not in use, thereby reducing the space occupied by the folding guardrail when not in use. This facilitates production operations and passage for operators around the folding guardrail, thereby meeting the requirements of efficient and convenient operation.

[0006] To solve the above-mentioned technical problems, this utility model discloses a folding guardrail, comprising:

[0007] The lower horizontal bar extends along the first direction;

[0008] The upper crossbar is located above the lower crossbar and extends along the first direction;

[0009] At least two vertical bars are provided between the upper horizontal bar and the lower horizontal bar. The vertical bars are arranged sequentially at intervals along the first direction. The vertical bars are parallel to each other. The upper end of each vertical bar is hinged to the upper horizontal bar, and the lower end of each vertical bar is hinged to the lower horizontal bar.

[0010] A limiting block is provided on one of the vertical bars. The limiting block has a first insertion hole, and the upper horizontal bar has a second insertion hole that passes through the upper horizontal bar along a second direction. The second direction is perpendicular to the first direction.

[0011] A pin is located inside the second socket, and the pin can slide within the second socket.

[0012] The vertical bar can rotate relative to the lower horizontal bar between a first position and a second position; when the vertical bar rotates to the first position, the guardrail is in a folded state; when the vertical bar rotates to the second position, the guardrail is in an unfolded state, and the pin can be inserted into the first socket when the vertical bar rotates to the second position.

[0013] According to another specific embodiment of the present invention, when the vertical rod is rotated to the second position, the vertical rod is perpendicular to the first direction.

[0014] According to another specific embodiment of the present invention, a folding guardrail is disclosed, which further includes hinge seats. The lower surface of the upper horizontal bar and the upper surface of the lower horizontal bar are provided with a plurality of hinge seats spaced apart along a first direction. Each vertical bar is hinged to its corresponding hinge seat.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a hinge seat comprising:

[0016] A fixing plate is provided on the lower surface of the upper crossbar or the upper surface of the lower crossbar;

[0017] Two ears are spaced apart on the fixed plate along a third direction, which is perpendicular to the first and second directions respectively. The end of the vertical rod is located between the two ears and is hinged to the ears.

[0018] A limiting plate is provided on one side of the two ears along the first direction. The limiting plate is perpendicular to the first direction. The limiting plate is used to restrict the vertical rod from continuing to rotate toward the limiting plate when the vertical rod rotates to the second position.

[0019] According to another specific embodiment of the present invention, an L-shaped limiting block is disclosed, the limiting block comprising:

[0020] The connecting part extends along the extension direction of the vertical rod and is connected to the vertical rod;

[0021] A locking part is provided on the side wall of the connecting part near the pin. The extending direction of the locking part is perpendicular to the extending direction of the connecting part. A first insertion hole is provided on the locking part.

[0022] According to another specific embodiment of the present invention, the embodiment of the present invention discloses that the connecting part is provided with a connecting hole that penetrates the connecting part along the extending direction of the connecting part, and the connecting hole is sleeved on the outside of the vertical rod.

[0023] According to another specific embodiment of the present invention, the embodiment of the present invention discloses that the pin is provided with a limiting protrusion, the limiting protrusion is located below the second insertion hole, and the diameter of the limiting protrusion is larger than the diameter of the second insertion hole.

[0024] According to another specific embodiment of the present invention, a folding guardrail further includes a baffle, which is disposed below the lower crossbar along a first direction and extends along the first direction.

[0025] The present invention also discloses a winding machine, including the folding guardrail and the fixed guardrail mentioned in any of the above embodiments, wherein the folding guardrail and the fixed guardrail are both located on the top of the winding machine.

The mounting frame is installed on the top of the winding and splicing machine, and the lower crossbar is connected to the winding and splicing machine through the mounting frame.

[0027] Compared with the prior art, this utility model has the following beneficial effects:

[0028] This utility model provides a folding guardrail comprising an upper horizontal bar, a lower horizontal bar, at least two vertical bars, a limiting block, and a pin. When an operator needs to work on top of the coiling machine, they first pull the upper horizontal bar upwards, causing it to rotate the vertical bars to a second position. While pulling the upper horizontal bar upwards, the pin is also pulled upwards until the limiting protrusion contacts the lower surface of the upper horizontal bar. When the vertical bar rotates to the second position, the pin is released, allowing it to insert into a first insertion hole, thus restricting the rotation of the vertical bar through the engagement of the pin and the first insertion hole. When the operator finishes working on top of the coiling machine, they pull the pin upwards to disengage it from the first insertion hole, and then press the upper horizontal bar to rotate the vertical bar back to the first position. This reduces the space occupied by the folding guardrail when not in use, facilitating production operations and passage for operators around the guardrail, thereby meeting the requirements of efficient and convenient operation.

They are only for the convenience of describing the utility model and simplifying the description, 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 the utility model.

[0039] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0041] 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.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a folding guardrail, including: a lower horizontal bar 1, an upper horizontal bar 2, at least two vertical bars 3, a limiting block 4, and a pin 5.

[0043] Specifically, the lower horizontal bar 1 is along the first direction (e.g. Figure 1 and Figure 2 (Extends in the X direction shown).

[0044] The upper crossbar 2 is located above the lower crossbar 1 and extends along the X direction.

[0045] Each vertical rod 3 is located between the upper horizontal rod 2 and the lower horizontal rod 1. Each vertical rod 3 is arranged sequentially at intervals along the X direction. Each vertical rod 3 is parallel to each other. The upper end of each vertical rod 3 is hinged to the upper horizontal rod 2, and the lower end of each vertical rod 3 is hinged to the lower horizontal rod 1.

[0046] like Figure 6 As shown, the limiting block 4 is mounted on one of the vertical rods 3, and the limiting block 4 has a first insertion hole 41. The upper horizontal rod 2 has a hole along the second direction (e.g., Figure 1 and Figure 2 The Y direction shown in the figure passes through the second insertion hole 21 of the upper crossbar 2, and the Y direction is perpendicular to the X direction.

[0047] The pin 5 is located inside the second socket 21 and can slide within the second socket 21.

[0048] The vertical bar 3 can be in the first position relative to the lower horizontal bar 1 (e.g.) Figure 2 The position of the vertical rod 3 shown) and the second position (as shown) Figure 1 The guardrail rotates between the positions of the vertical rod 3 shown in the diagram; when the vertical rod 3 rotates to the first position, the guardrail is in a folded state; when the vertical rod 3 rotates to the second position, the guardrail is in an unfolded state, and the pin 5 can be inserted into the first insertion hole 41 when the vertical rod 3 rotates to the second position. For example, when the guardrail is in the unfolded state, the vertical rod 3 extends along the Y direction.

[0049] The folding guardrail provided in this application can be applied to various working conditions. For example, the folding guardrail provided in this application can be installed on top of a winding machine to protect the safety of workers operating on top of the winding machine.

[0050] This application allows the folding guardrail to be unfolded or folded by configuring the vertical rods 3 to rotate between a first position and a second position. By setting a limiting block 4 and a pin 5, when the folding guardrail is in the unfolded state, the pin 5 can be inserted into the first insertion hole 41 of the limiting block 4 to lock the folding guardrail and prevent the vertical rods 3 from rotating when the folding guardrail is unfolded. When it is necessary to fold the guardrail, the pin 5 can be pulled out of the first insertion hole 41, and then a force can be applied to the upper horizontal bar 2, causing each vertical rod 3 to rotate to the first position, thus folding the guardrail. This reduces the space occupied by the folding guardrail when not in use, facilitating production operations and passage for operators around the folding guardrail, thereby meeting the requirements of efficient and convenient operation.

[0051] In some implementations, reference Figure 3 and Figure 5 The pin 5 has a limiting protrusion 51 located below the second socket 21. Specifically, the limiting protrusion 51 is annular and fits onto the circumferential surface of the pin 5. The diameter of the limiting protrusion 51 is larger than the diameter of the second socket 21. By providing the limiting protrusion 51, this application can prevent the operator from pulling the pin 5 out of the second socket 21, thereby preventing the pin 5 from being lost.

[0052] Specifically, when the operator needs to work on the top of the winding and splicing machine 9, they first pull the upper horizontal bar 2 upwards along the Y direction, causing the upper horizontal bar 2 to rotate the vertical bar 3 to the second position. While pulling the upper horizontal bar 2 upwards, the operator also pulls the pin 5 upwards along the Y direction until the limiting protrusion 51 contacts the lower surface of the upper horizontal bar 2. When the vertical bar 3 rotates to the second position, the operator releases the pin 5, causing the pin 5 to insert downwards along the Y direction into the first insertion hole 41, thereby restricting the rotation of the vertical bar 3 through the engagement of the pin 5 and the first insertion hole 41. When the operator finishes working on the top of the winding and splicing machine 9, the operator pulls the pin 5 upwards along the Y direction to remove it from the first insertion hole 41. Subsequently, the operator presses the upper horizontal bar 2 downwards along the Y direction, causing the vertical bar 3 to rotate to the first position.

[0053] Furthermore, such as Figure 4 As shown, a folding guardrail also includes hinge seats 6. Multiple hinge seats 6 are provided at intervals along the X direction on the lower surface of the upper horizontal bar 2 and the upper surface of the lower horizontal bar 1. Each vertical bar 3 is hinged to its corresponding hinge seat 6. By providing hinge seats 6, this application allows the vertical bars 3 to be hinged to the upper horizontal bar 2 and the lower horizontal bar 1, enabling the folding and unfolding of the guardrail.

[0054] Optionally, refer to Figure 4 and Figure 7 A hinge seat 6 includes:

[0055] The fixing plate 61 is provided on the lower surface of the upper crossbar 2 or the upper surface of the lower crossbar 1;

[0056] Two ears 62, along a third direction (such as...) Figure 4 and Figure 7 The Z-direction shown is spaced on the fixed plate 61, and the Z-direction is perpendicular to the X-direction and Y-direction respectively. The end of the vertical rod 3 is located between the two ears 62, and the end of the vertical rod 3 is hinged to the ears 62.

[0057] A limiting plate 63 is provided on one side of the two ears 62 along the X direction. The limiting plate 63 is perpendicular to the X direction. The limiting plate 63 is used to restrict the vertical rod 3 from continuing to rotate toward the limiting plate 63 when the vertical rod 3 rotates to the second position.

[0058] This utility model's folding guardrail features two lugs 62, allowing the end of the vertical rod 3 to be hinged between them, enabling the vertical rod to rotate between the lugs 62. A limiting plate 63 is provided between the two lugs 62 to limit the rotation of the vertical rod 3. Specifically, when the vertical rod 3 rotates to the second position, it contacts the limiting plate 63, preventing further rotation that could make the folding guardrail difficult to secure, thus improving the convenience of using the folding guardrail.

[0059] In some implementations, reference Figure 3 , Figure 5 and Figure 6 The limiting block 4 is L-shaped and includes:

[0060] The connecting part 42 extends along the extension direction of the vertical rod 3 and is connected to the vertical rod 3. For example, the connecting part 42 is provided with a connecting hole 421 that extends through the connecting part 42 along its own extension direction and is sleeved on the outside of the vertical rod 3.

[0061] The locking part 43 is provided on the side wall of the connecting part 42 near the pin 5. The extending direction of the locking part 43 is perpendicular to the extending direction of the connecting part 42. The first insertion hole 41 is provided on the locking part 43.

[0062] Furthermore, the connecting part 42 is detachably connected to the vertical rod 3 by bolts. The vertical rod 3 is provided with a plurality of threaded holes (not shown in the figure) spaced apart along its extension direction. By connecting the connecting part 42 to different threaded holes, the position of the connecting part 42 on the vertical rod 3 can be adjusted, thereby enabling the connecting part 42 to be used with pins 5 of different lengths, enhancing the versatility of the connecting part 42.

[0063] For example, such as Figure 1 and Figure 2 As shown, the folding guardrail also includes a baffle 7, which is located below the lower crossbar 1 along the X direction and extends along the X direction. By providing the baffle 7, this application can prevent debris from falling from the top of the coiling machine to the ground, thereby avoiding production safety problems.

[0064] Based on the same concept, referencing Figure 1 The present invention also provides a winding machine, including the folding guardrail and the fixed guardrail 8 provided in the above embodiments. The folding guardrail and the fixed guardrail 8 are both located on the top of the winding machine 9, thereby forming a safety protection structure together.

[0065] In some implementations, such as Figure 1 and Figure 2 The winding machine also includes a mounting frame 91, which is installed on the top of the winding machine 9. The lower crossbar 1 is connected to the winding machine 9 through the mounting frame 91 to achieve a fixed connection between the folding guardrail and the top of the winding machine 9.

[0066] It should be noted that in the examples and description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," 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 limitations, 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 the element.

[0067] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
