Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco pack unpacking clamp. Background Technology

[0002] Unpacking the tobacco leaf packs is the first step in the process of bringing tobacco leaf raw materials into the tobacco processing workshop. Specifically, a plastic bag is placed over the tobacco leaf pack, followed by inner cardboard linings at the top and bottom of the plastic bag, and finally a cardboard box is placed over it. This packaging of the tobacco leaf packs, consisting of the plastic bag, inner cardboard lining, and cardboard box, ensures stable and safe transport. Unpacking the tobacco leaf packs requires the use of unpacking clamps to dismantle the cardboard box, inner cardboard lining, and plastic bag, allowing the tobacco leaf packs to be directly delivered into the tobacco processing workshop for processing. A tobacco leaf pack specifically refers to a single bundle structure formed by stacking multiple pieces of tobacco leaves that have been destemmed and cut into individual pieces.

[0003] However, as Figure 1 As shown, since the current cigarette pack unpacking clamps only have a connected conical surface 11' and a cylindrical surface 12', and the diameter of the circular base of the conical surface 11' is equal to the diameter of the cylindrical surface 12', the inner lining cardboard is prone to falling off the conical surface 11' on the clamps 1', which is not conducive to the smooth unpacking of the cigarette packs.

[0004] To address the above problems, there is an urgent need for a cigarette pack unpacking clamp. Utility Model Content

[0005] The purpose of this utility model is to provide a cigarette pack unpacking clamp that can ensure that the rivets can be easily pierced by the inner cardboard lining and are not easily dropped; and ensure that the plastic bag is not pulled up when the rivets pierce the inner cardboard lining, thereby facilitating the smooth unpacking of the cigarette pack.

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

[0007] A cigarette pack unpacking clamp, wherein the cigarette pack is covered with a plastic bag, and an inner cardboard lining is placed at the top and bottom of the plastic bag; the cigarette pack unpacking clamp includes:

[0008] The main frame is located above the tobacco pack, and the main frame can move along the X-axis, Y-axis and Z-axis respectively;

[0009] The main frame is connected with a plurality of spaced-apart staples. Each staple has a conical surface, a first cylindrical surface, and a second cylindrical surface connected in sequence. The diameter of the circular base of the conical surface is equal to the diameter of the first cylindrical surface, and the diameter of the second cylindrical surface is smaller than the diameter of the first cylindrical surface. The staple is used to puncture the inner lining cardboard downward along the Z-axis so that the inner lining cardboard is placed on the outer circumferential surface of the second cylindrical surface.

[0010] As an optional solution, a guide arc surface connects the circular bottom surface of the conical surface to the first cylindrical surface.

[0011] Alternatively, the number of rivets may be greater than or equal to five.

[0012] As an optional solution, the main frame includes:

[0013] A vertical plate and two horizontal plates are arranged in parallel, with one end of each horizontal plate connected to the opposite ends of the vertical plate to form a U-shaped main frame. A portion of the rivets are connected to the inner side of the U-shaped structure, and another portion of the rivets are connected to the outer side of the U-shaped structure.

[0014] As an optional solution, the cigarette pack unpacking clamp also includes:

[0015] An auxiliary component, one end of which is connected to the main frame and the other end of which can move toward or away from the tobacco pack, is capable of pushing off the inner lining cardboard that is stuck on the rivet, and the rivet can slide through the auxiliary component.

[0016] As an optional solution, the auxiliary components include:

[0017] A driving component, the fixed end of which is located on the main frame, and the driving component is spaced apart on one side of the rivet;

[0018] A baffle is provided, with the driving end of the driving member connected to the baffle. The driving member is used to drive the baffle to move towards or away from the tobacco pack. The baffle is used to push off the inner lining cardboard that is stuck on the rivet, and the rivet can slide through the baffle.

[0019] As an optional solution, the baffle is provided with a through hole, through which the rivet can slide and pass, and the diameter of the through hole is equal to the diameter of the first cylindrical surface.

[0020] As an optional solution, the cigarette pack unpacking clamp also includes:

[0021] A support base is connected to the main frame, and both the rivet and the drive component are connected to the support base.

[0022] As an optional solution, the cigarette pack unpacking clamp also includes:

[0023] The clamping assembly includes two clamping members disposed opposite to each other on the main frame. The two clamping members can move away from or close to each other so that the two clamping members can loosen or clamp the plastic bag.

[0024] As an optional solution, the number of clamping components is greater than or equal to two.

[0025] The beneficial effects of this utility model are as follows:

[0026] By enabling the main frame to move along the X, Y, and Z axes respectively, the relative position of the main frame to the cigarette pack can be adjusted, facilitating the subsequent removal and unpacking of the plastic bag and inner cardboard lining of the cigarette pack. The rivet has a conical surface, a first cylindrical surface, and a second cylindrical surface connected in sequence, with the diameter of the circular base of the conical surface equal to the diameter of the first cylindrical surface, and the diameter of the second cylindrical surface smaller than the diameter of the first cylindrical surface. This allows the rivet to pierce the inner cardboard lining downwards along the Z-axis, and when the inner cardboard lining is lifted onto the rivet, it allows the inner cardboard lining to pass sequentially through the conical surface and the first cylindrical surface. The first cylindrical surface is placed on the outer circumference of the second cylindrical surface. Because a stepped structure is formed at the connection between the first and second cylindrical surfaces, the inner lining cardboard is not easily dropped off the rivet by the step structure, thus ensuring that the rivet can easily pierce the inner lining cardboard and is not easy to fall off. Furthermore, because the plastic bag is relatively light, when the rivet pierces the inner lining cardboard, the transition connection between the conical surface and the first cylindrical surface can provide frictional resistance for the plastic bag, thus ensuring that the plastic bag is not easily pulled up when the rivet pierces the inner lining cardboard, which is conducive to the smooth unpacking of the cigarette pack.

[0038] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0039] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] This embodiment proposes a cigarette pack unpacking clamp. A plastic bag is placed over the cigarette pack, and inner cardboard is placed at the top and bottom of the plastic bag. A cardboard box is then placed over the outermost part of the bag. This allows the cigarette pack to be packaged using the plastic bag, inner cardboard, and cardboard box, facilitating stable and safe transportation of the packaged cigarette pack. Unpacking the cigarette pack requires using this unpacking clamp to disassemble the cardboard box, inner cardboard, and plastic bag, allowing the cigarette pack to be directly sent into the tobacco processing workshop to begin tobacco processing.

[0041] It is worth noting that the cigarette pack unpacking fixture in this embodiment is mainly used to remove the plastic bag and inner cardboard lining of the cigarette pack. That is, the outer cardboard box of the cigarette pack in this embodiment has been removed in advance. Here, the specific unpacking process of the cardboard box is not described in detail. You can refer to the existing unpacking process of cigarette packs.

[0042] The cigarette pack unpacking clamp in this embodiment can ensure that the inner cardboard liner can be easily punctured and is not easily dropped, which is conducive to the smooth disassembly of the inner cardboard liner; at the same time, it can ensure that the lightweight plastic bag is not easily pulled up when puncturing the inner cardboard liner, which is conducive to the smooth disassembly of the plastic bag; thus, it is conducive to the smooth unpacking of the cigarette pack.

[0043] like Figure 2 and Figure 3As shown, the specific structure of the rivet 2 and the main frame 1 is described in detail below:

[0044] Specifically, such as Figure 2 and Figure 3 As shown, the cigarette pack unpacking clamp includes a main frame 1 and rivets 2. The main frame 1 is located above the cigarette pack and can move along the X-axis, Y-axis, and Z-axis to adjust its relative position to the cigarette pack, which facilitates the subsequent removal and unpacking of the plastic bag and inner cardboard lining. Multiple rivets 2 are spaced apart on the main frame 1. Each rivet 2 has a conical surface 21, a first cylindrical surface 22, and a second cylindrical surface 23 connected in sequence. The diameter of the circular base of the conical surface 21 is equal to the diameter of the first cylindrical surface 22, and the diameter of the second cylindrical surface 23 is smaller than the diameter of the first cylindrical surface 22. The rivets 2 are used to pierce the inner cardboard lining downwards along the Z-axis, so that the inner cardboard lining is placed on the outer circumference of the second cylindrical surface 23. The rivets 2 and the inner cardboard lining on them are removed relative to the cigarette pack, thereby enabling the inner lining pad on the plastic bag to be lifted and unpacked using the rivets 2.

[0045] Compared to existing technologies, the unpacking clamp for cigarette packs in this embodiment changes the specific arrangement of the rivet 2. By making the rivet 2 have a conical surface 21, a first cylindrical surface 22, and a second cylindrical surface 23 connected in sequence, and making the diameter of the circular base of the conical surface 21 equal to the diameter of the first cylindrical surface 22, and the diameter of the second cylindrical surface 23 smaller than the diameter of the first cylindrical surface 22, it is possible for the rivet 2 to pierce the inner lining cardboard downward along the Z-axis. When the inner lining cardboard is pierced onto the rivet 2, it is possible for the inner lining cardboard to pass through the conical surface 21 and the first cylindrical surface 22 in sequence and then be placed on the outer circumferential surface of the second cylindrical surface 23. Since the first cylindrical surface 22 and the second cylindrical surface 23 are connected, the rivet 2 can be used to pierce the inner lining cardboard downward along the Z-axis. When the inner lining cardboard is pierced onto the rivet 2, it can be placed on the outer circumferential surface of the second cylindrical surface 23 after passing through the conical surface 21 and the first cylindrical surface 22 in sequence. The connection between surfaces 23 forms a stepped structure 24, which restricts and prevents the inner lining cardboard from falling off the rivet 2, thus ensuring that the rivet 2 does not easily fall off the inner lining cardboard. The inclined conical surface 21 provides guidance for the piercing of the inner lining cardboard, ensuring that the inner lining cardboard is pierced smoothly. Furthermore, since the plastic bag is relatively light, when the rivet 2 pierces the inner lining cardboard, the transition connection between the conical surface 21 and the first cylindrical surface 22 provides frictional resistance to the plastic bag, thus ensuring that the plastic bag is not easily pulled up when the rivet 2 pierces the cardboard, which is conducive to the smooth unpacking of the cigarette pack.

[0046] Furthermore, a guide arc surface (not shown in the figure) connects the circular bottom surface of the conical surface 21 to the first cylindrical surface 22. On the one hand, the guide arc surface can provide guidance for the inner lining cardboard, so that when the rivet 2 pokes the inner lining cardboard, the inner lining cardboard can be smoothly moved to the outer circumference of the second cylindrical surface 23, so as to better ensure that the rivet 2 can smoothly poke the inner lining cardboard. On the other hand, the guide arc surface can provide greater frictional resistance for the plastic bag, so as to better ensure that the plastic bag is not easily pulled up when the rivet 2 pokes the inner lining cardboard.

[0047] Specifically, such as Figure 2 As shown, the number of rivets 2 is greater than or equal to five, so that the inner lining cardboard can be punctured simultaneously by five or more rivets 2. This increases the puncturing area between the rivets 2 and the inner lining cardboard, thereby increasing the puncturing force of the rivets 2 on the inner lining cardboard. This better ensures that the rivets 2 can be easily punctured and are less likely to fall off, and also prevents the plastic bag from being pulled up when the rivets 2 puncture the inner lining cardboard, further facilitating the easy unpacking of the cigarette pack. In this embodiment, the number of rivets 2 is set to five. Here, the specific number of rivets 2 is not limited, as long as it is greater than or equal to five.

[0048] Furthermore, such as Figure 2 As shown, the main frame 1 includes a vertical plate 12 and two horizontal plates 11. The two horizontal plates 11 are arranged in parallel, and one end of each horizontal plate 11 is connected to the opposite ends of the vertical plate 12 to form a U-shaped main frame 1. This makes the overall structure of the main frame 1 simple, lightweight, and low-cost. The vertical plate 12 and the horizontal plates 11 can be integrally formed or separate structures.

[0049] Specifically, such as Figure 2 As shown, some of the staples 2 are connected to the inner side of the U-shaped structure, and others are connected to the outer side of the U-shaped structure, so that the connection positions of each staple 2 on the entire main frame 1 can be reasonably arranged. When the reasonably arranged staples 2 simultaneously puncture the inner lining cardboard, it can ensure that staples 2 puncture every position on the inner lining cardboard, thereby ensuring a balanced distribution of the puncturing force of each staple 2 on the inner lining cardboard, so as to better ensure that the inner lining cardboard is successfully punctured and not easily falls off. In this embodiment, two staples 2 are connected to the inner side of the U-shaped structure, and three staples 2 are connected to the outer side of the U-shaped structure.

[0050] like Figure 2 As shown, the specific structure of auxiliary component 3 is described in detail below:

[0051] Specifically, such as Figure 2As shown, the cigarette pack unpacking clamp also includes an auxiliary component 3. One end of the auxiliary component 3 is connected to the main frame 1, and the other end of the auxiliary component 3 can move towards or away from the cigarette pack. The auxiliary component 3 can push off the inner cardboard lining stuck on the rivet 2, and the rivet 2 can slide through the auxiliary component 3.

[0052] Furthermore, the auxiliary component 3 includes a drive member and a baffle; wherein, the fixed end of the drive member is located on the main frame 1, and the drive member is spaced apart on one side of the rivet 2 to ensure that there is no interference between the drive member and the rivet 2, and to ensure good independence of their respective operations; the drive end of the drive member is connected to the baffle, and the drive member is used to drive the baffle to move closer to or away from the tobacco pack, the baffle is used to push off the inner lining cardboard stuck on the rivet 2, and the rivet 2 can slide through the baffle. In this embodiment, the drive member can specifically be a linear cylinder.

[0053] Specifically, when unpacking the inner linerboard, the main frame 1 is first moved along the X-axis and / or Y-axis and / or Z-axis so that the main frame 1 moves the tie 2 to puncture the inner linerboard; then, the main frame 1 is moved along the X-axis and / or Y-axis and / or Z-axis so that the main frame 1 moves the tie 2 and the inner linerboard on it away from the cigarette pack; finally, the drive unit drives the baffle to move closer to the inner linerboard so that the baffle pushes off the inner linerboard on the tie 2 so that the pushed-off inner linerboard can be collected by the collection box, thereby achieving unified recycling management of the inner linerboard.

[0054] It is worth noting that during the process of the baffle pushing off the inner lining cardboard, the nail 2 remains stationary, the baffle moves towards the inner lining cardboard, and the nail 2 can slide through the baffle to ensure that the baffle and the nail 2 do not interfere with each other, thereby better ensuring that the baffle can smoothly push off the inner lining cardboard on the nail 2.

[0055] Furthermore, the baffle is provided with a through hole, through which the rivet 2 can slide to ensure that the baffle and the rivet 2 do not interfere with each other; and the sliding of the rivet 2 in the through hole can provide guidance for the movement of the baffle towards or away from the inner lining cardboard, thereby ensuring the guidance and stability of the movement of the baffle.

[0056] Specifically, the diameter of the through hole is equal to the diameter of the first cylindrical surface 22. That is, the diameter of the through hole is exactly matched with the diameter of the tie 2, so that the diameter of the through hole can be reduced as much as possible while ensuring that the tie 2 slides through. This avoids the problem that the plastic bag is easily sucked away from the through hole due to the through hole being too large, and further ensures that the plastic bag is not easily pulled up when the tie 2 pokes the inner cardboard.

[0057] It is worth noting that, such as Figure 3As shown, the difference between the diameter of the first cylindrical surface 22 and the diameter of the second cylindrical surface 23 is small, so that the baffle can smoothly push off the inner lining cardboard stuck on the tack 2 while ensuring that the limiting barrier of the step structure 24 prevents the inner lining cardboard from falling off the tack 2. This avoids the step structure 24 interfering with the pushing operation of the inner lining cardboard, and thus ensures that the baffle smoothly pushes the inner lining cardboard on the tack 2 into the collection box.

[0058] Furthermore, such as Figure 2 As shown, the cigarette pack unpacking clamp also includes a support base 4, which is connected to the main frame 1. The tie pins 2 and the driving component are both connected to the support base 4, making the overall structure of the cigarette pack unpacking clamp more reasonable and compact, thus reducing the area occupied by the clamp. The support base 4 can be fixedly connected to the horizontal plate 11 or the vertical plate 12 of the main frame 1, or to the connection point between the horizontal plate 11 and the vertical plate 12. The specific connection position of the support base 4 on the main frame 1 is not limited here.

[0059] like Figure 2 As shown, the specific structure of the clamping assembly 5 will be described in detail below:

[0060] Specifically, such as Figure 2 As shown, the cigarette pack unpacking clamp also includes a clamping component group 5, which includes two clamping components 51 that are arranged opposite to each other on the horizontal plates 11 of the main frame 1. That is, the two clamping components 51 are arranged opposite to each other on the two horizontal plates 11. The two clamping components 51 can move away from or close to each other so that the two clamping components 51 can loosen or clamp the plastic bag, thereby enabling the unpacking of the plastic bag through the two clamping components 51.

[0061] Among them, such as Figure 2 and Figure 4 As shown, the clamping member 51 includes a combination structure of a linear cylinder and a clamping plate 511, so that the clamping plate 511 is driven to move by the linear cylinder, allowing the two clamping plates 511 to move closer or further apart, thereby loosening or clamping the plastic bag. Here, the specific structure of the clamping member 51 is not limited, as long as it can clamp the plastic bag.

[0062] Specifically, in order to facilitate the removal and unpacking of the plastic bag, the plastic bag can be pre-cut into two parts from the middle. First, the upper part of the plastic bag outside the cigarette pack is clamped and removed using the two clamping pieces 51. Then, the entire cigarette pack is flipped over, and the lower part of the plastic bag outside the cigarette pack is clamped and removed using the two clamping pieces 51, thereby achieving the unpacking of the plastic bag.

[0063] Furthermore, such as Figure 2As shown, the number of clamping member groups 5 is greater than or equal to two groups, so that the plastic bag can be clamped simultaneously by two or more groups of clamping member groups 5. This increases the clamping area between the clamping member 51 and the plastic bag, thereby increasing the clamping force of the clamping member 51 on the plastic bag. This helps to avoid the problem of the clamping member 51 failing to grasp the plastic bag, and further facilitates the smooth unpacking of the cigarette pack. In this embodiment, the number of clamping member groups 5 is set to two groups. Here, the specific number of clamping member groups 5 is not limited, as long as it is greater than or equal to two groups.

[0064] The specific working process of the cigarette pack unpacking clamp in this embodiment is as follows:

[0065] First, the main frame 1 is moved along the X-axis and / or Y-axis and / or Z-axis so that the main frame 1 moves the tie 2 to puncture the inner lining cardboard; then, the main frame 1 is moved along the X-axis and / or Y-axis and / or Z-axis so that the main frame 1 moves the tie 2 and the inner lining cardboard on it away from the cigarette pack; then, the driving component drives the baffle to move closer to the inner lining cardboard so that the baffle pushes the inner lining cardboard on the tie 2 into the collection box, so as to remove the inner lining cardboard and collect it into the collection box.

[0066] Then, the main frame 1 is moved along the X-axis and / or Y-axis and / or Z-axis, so that the main frame 1 drives the two clamping parts 51 of the clamping parts group 5 to move to opposite sides of the plastic bag; then, the two clamping parts 51 are brought together to clamp the plastic bag, and the main frame 1 is moved along the X-axis and / or Y-axis and / or Z-axis, so that the main frame 1 drives the clamping parts group 5 and the clamped plastic bag away from the cigarette pack and moves to directly above the recycling bin; then, the two clamping parts 51 are moved away from each other to release the plastic bag, so that the plastic bag automatically falls into the recycling bin, thereby removing the plastic bag and uniformly recycling it into the recycling bin.

[0067] The cigarette pack unpacking clamp in this embodiment has a conical surface 21, a first cylindrical surface 22, and a second cylindrical surface 23 connected in sequence on the rivet 2. The diameter of the circular base of the conical surface 21 is equal to the diameter of the first cylindrical surface 22, and the diameter of the second cylindrical surface 23 is smaller than the diameter of the first cylindrical surface 22. This can prevent the inner lining cardboard from falling off the rivet 2, ensuring that the rivet 2 can easily poke the inner lining cardboard and is not easy to fall off. It can also ensure that the plastic bag is not easily pulled up when the rivet 2 pokes the cardboard.

[0068] The cigarette pack unpacking clamp in this embodiment uses five or more rivets 2 to simultaneously puncture the inner lining cardboard. This increases the puncturing force of the rivets 2 on the inner lining cardboard, thereby better ensuring that the rivets 2 can smoothly puncture the inner lining cardboard and are not easy to fall off. It also prevents the plastic bag from being pulled up when the rivets 2 puncture the inner lining cardboard.

[0069] In this embodiment, the cigarette pack unpacking clamp makes the diameter of the through hole on the baffle equal to the diameter of the first cylindrical surface 22 of the rivet 2. This avoids the problem that the plastic bag is easily sucked away from the through hole due to the through hole being too large, and thus further ensures that the plastic bag is not easily pulled up when the rivet 2 pokes the inner cardboard.

[0070] In this embodiment, the cigarette pack unpacking clamp uses two or more sets of clamping members 5 to simultaneously clamp the plastic bag, thereby increasing the clamping force of the clamping members 51 on the plastic bag and thus avoiding the problem of the clamping members 51 failing to grasp the plastic bag.

[0071] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
