Description
Technical Field
[0001] This utility model relates to the field of cigarette box disassembly and repair technology, and in particular to a box disassembly tooling. Background Technology
[0002] The cigarette mold box of a tobacco packaging machine is an important component of the cigarette conveying system, used to neatly arrange the cigarettes transported from the cigarette warehouse and convey them to the next packaging station. The mold box base plate is bolted to the cigarette mold box conveyor belt, and the mold box, which holds the cigarettes, is mounted on the base plate. See also... Figure 1 The base plate 1 and the mold box 2 are fixed in position by elastic retaining strips 11. Specifically, there is an elastic retaining strip 11 on each side of the base plate 1. The two elastic retaining strips 11 can apply force to the mold box 2 to clamp the mold box 2 onto the base plate 1. When it is necessary to remove the mold box 2 from the base plate 1, see [link to relevant documentation]. Figure 2 The operator moves the two elastic clips 11 to both sides, causing the two elastic clips 11 to undergo elastic deformation towards the outside. After the mold box 2 loses the clamping force of the two elastic clips 11, the operator can pull the mold box 2 off the base plate 1 to complete the disassembly.
[0003] Currently, disassembling the cigarette mold box requires two operators working together. One operator uses two flathead screwdrivers in each hand to simultaneously pry open the two spring clips to release them from the cigarette mold box. Then, the other operator pulls the cigarette mold box out of the base plate. Because this operation requires two people and is time-consuming, it significantly impacts the efficiency of disassembling the mold box. Utility Model Content
[0004] The purpose of this invention is to solve the technical problems of long time consumption and low efficiency in existing cigarette mold disassembly methods. This invention provides a mold disassembly fixture, which allows only one person to quickly disassemble the cigarette mold, reducing disassembly time and improving disassembly efficiency.
[0005] To solve the above-mentioned technical problems, this utility model discloses a mold box disassembly fixture for disassembling a mold box mounted on a base plate. The base plate is provided with two elastic retaining strips spaced apart along a first direction. The two elastic retaining strips are used to clamp the mold box and lock it onto the base plate. The mold box disassembly fixture includes:
[0006] Connecting plate;
[0007] Two pressure plates are perpendicular to the connecting plate. The two pressure plates are spaced apart on the connecting plate along the first direction. The distance between the two pressure plates is greater than or equal to the size of the mold box along the first direction. The first ends of the two pressure plates are respectively connected to the connecting plate. The second ends of the two pressure plates are respectively used to apply force to the two elastic clips so that the elastic clips produce elastic deformation.
[0008] An adjustment mechanism is located between the connecting plate and the pressure plate. The adjustment mechanism is used to adjust the distance between the two pressure plates.
[0009] When disassembling the mold box, the operator first adjusts the distance between the two pressure plates using the adjustment mechanism, allowing the mold box to be inserted between them. Then, the operator holds the connecting plate with one hand, ensuring the lower ends of the two pressure plates contact the two elastic retaining strips, and presses down on the strips. Under this pressure, the two retaining strips deform outwards, releasing their lock on the mold box. The operator then uses their other hand to pull the mold box outwards, disengaging it from the base plate and quickly completing the disassembly.
[0010] Using the above technical solution, the mold box can be disassembled by a single person, saving time and improving disassembly efficiency. Furthermore, the distance between the two pressure plates can be adjusted according to the mold box's dimensions before disassembly, making the mold box disassembly fixture applicable to disassembling various mold boxes of different sizes, thus increasing its versatility.
[0011] Optionally, the adjustment mechanism includes:
[0012] A sliding groove is provided on the outer surface of the connecting plate, and the sliding groove extends along a first direction;
[0013] The movable block is at least partially disposed in the slide groove, and the movable block is able to slide in the slide groove along a first direction. The movable block is connected to the first end of the pressure plate.
[0014] Locking element, used to lock the position of the moving block.
[0015] The above-mentioned technical solution results in a simple structure and convenient operation of the adjustment mechanism.
[0016] Optionally, there is one moving block and one locking element. The moving block is connected to the first end of one pressure plate, and the first end of the other pressure plate is fixedly connected to the connecting plate. The locking element is used to lock the position of the moving block.
[0017] Optionally, there are two moving blocks and two locking elements. The two moving blocks are connected to the first ends of the two pressure plates respectively, and the two locking elements are used to lock the positions of the two moving blocks respectively.
[0018] The above technical solution allows operators to adjust the position of any one or both pressure plates as needed, providing greater flexibility.
[0019] Optionally, the locking element is a locking screw; the connecting plate is provided with an oblong hole extending in the first direction, the oblong hole penetrates the connecting plate along the thickness direction, the moving block is provided with a threaded hole, and the locking screw passes through the oblong hole and is threadedly connected to the threaded hole.
[0020] By adopting the above technical solution, the synergistic effect of the moving block, locking screw and oblong hole can improve the stability of the moving block position adjustment, avoid repeated adjustments by the operator, simplify the adjustment process and improve adjustment efficiency.
[0021] Optionally, each of the two pressure plates has an abutment portion at its second end, which is bent toward the inside of the pressure plate relative to the pressure plate, and the lower surface of the abutment portion is used to contact the elastic retaining strip.
[0022] The design of the abutment portion bending inward relative to the pressure plate, using the above technical solution, allows the shape of the abutment portion to better match the shape of the upper end of the elastic card strip.
[0023] Optionally, the distance between the lower surfaces of the two abutting portions gradually decreases along a second direction, which extends from the first end of the pressure plate to the second end of the pressure plate.
[0024] Optionally, the included angle between the lower surface of the abutment and the pressure plate ranges from 90° to 97°.
[0025] By adopting the above technical solution, the tilt angle of the abutment part is more matched with the tilt angle of the upper end of the elastic clip, which can increase the contact area between the lower surface of the abutment part and the elastic clip. When disassembling, the pressure distribution between the two contact surfaces is more uniform, avoiding damage to the mold box and its surrounding structural components due to uneven force.
[0026] Optionally, the connecting plate and the two pressure plates are both made of carbon steel.
[0027] Using the above technical solution, the disassembly tooling made of carbon steel is inexpensive, cost-effective, and has sufficient hardness and strength to meet the usage requirements. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.
[0042] 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.
[0043] See Figure 1 The base plate 1 is provided with a first direction (e.g. Figure 1 Two elastic retaining strips 11, spaced apart in the X direction (as shown in the diagram), are used to clamp the mold box 2 and lock it onto the base plate 1. To address the technical problem in the prior art where disassembling the cigarette mold box requires two people, is time-consuming, and inefficient, see [reference needed]. Figure 4 and Figure 5 The present invention discloses a mold box disassembly fixture for disassembling a mold box 2 installed on a base plate 1. The mold box disassembly fixture includes a connecting plate 3, two pressure plates 4 and an adjustment mechanism 5.
[0044] See Figure 3 Both pressure plates 4 are perpendicular to the connecting plate 3 and are spaced apart on the connecting plate 3 along the X direction. The distance between the two pressure plates 4 is greater than or equal to the dimension of the mold box 2 along the X direction, so that the mold box 2 can be inserted between the two pressure plates 4. The upper ends (i.e., the first ends of the pressure plates 4) of the two pressure plates 4 are respectively connected to the connecting plate 3, and the lower ends (i.e., the second ends of the pressure plates 4) of the two pressure plates 4 are respectively used to apply force to the two elastic retaining strips 11, so that the elastic retaining strips 11 produce elastic deformation. An adjusting mechanism 5 is provided between the connecting plate 3 and the pressure plates 4, and the adjusting mechanism 5 is used to adjust the distance between the two pressure plates 4.
[0045] When it is necessary to disassemble the mold box 2, the operator first adjusts the distance between the two pressure plates 4 using the adjusting mechanism 5, so that the mold box 2 can be inserted between the two pressure plates 4. Then, the operator holds the connecting plate 3 with one hand, so that the lower ends of the two pressure plates 4 contact the two elastic retaining strips 11 respectively, and moves along the second direction (e.g., Figure 4 As shown in the Y direction, press down on the two elastic retaining strips 11. At this time, the two elastic retaining strips 11 will produce an outward elastic deformation under the pressure, so as to release their locking to the mold box 2. Then, the operator uses the other hand to pull the mold box 2 outward to make the mold box 2 detach from the base plate 1, thereby quickly completing the disassembly of the mold box 2.
[0046] Using the above technical solution, the disassembly of mold box 2 can be completed by a single person, saving time and improving the disassembly efficiency. Furthermore, the spacing between the two pressure plates 4 can be adaptively adjusted according to the size of mold box 2 before disassembly, making the mold box disassembly fixture applicable to disassembling various sizes of mold boxes 2, thus increasing its versatility.
[0047] Further, see Figure 4 Both pressure plates 4 have abutment portions 41 at their lower ends. The abutment portions 41 are bent inward relative to the pressure plates 4, and their lower surfaces are used to contact the elastic clips 11. The upper ends of both elastic clips 11 are bent outward relative to themselves. The design of the abutment portions 41 bending inward relative to the pressure plates 4 allows the shape of the abutment portions 41 to better match the shape of the upper ends of the elastic clips 11.
[0048] Specifically, see Figure 4 The distance between the lower surfaces of the two abutting parts 41 gradually decreases along the Y direction, and the included angle between the lower surface of the abutting part 41 and the pressure plate 4 (e.g.) Figure 4 The angle (α) ranges from 90° to 97°. In one embodiment of this utility model, exemplarily, the included angle between the lower surface of the abutment portion 41 and the pressure plate 4 is 97°. This design makes the tilt angle of the abutment portion 41 more closely match the tilt angle of the upper end of the elastic clip 11, which increases the contact area between the lower surface of the abutment portion 41 and the elastic clip 11. During disassembly, the pressure distribution between the two contact surfaces is more uniform, avoiding damage to the mold box 2 and its surrounding structural components due to uneven force.
[0049] Further, see Figure 5The adjusting mechanism 5 includes a slide groove 51, a moving block 52, and a locking element. The slide groove 51 is disposed on the outer surface of the connecting plate 3 and extends in the X direction. The moving block 52 is at least partially disposed within the slide groove 51 and is capable of sliding within the slide groove 51 in the X direction. The moving block 52 is connected to the first end of the pressure plate 4. The locking element is used to lock the position of the moving block 52. Exemplarily, the locking element is a locking screw 53. The slide groove 51 is disposed on the outer surface of the connecting plate 3 on the side near the pressure plate 4 and extends through the connecting plate 3 along its extending direction.
[0050] Before use, the distance between the two pressure plates 4 needs to be adjusted. First, loosen the locking screw 53 to release its lock on the moving block 52. Then, adjust the distance between the two abutting parts 41 according to the size of the mold box 2 to be disassembled. If the distance is too large, move the pressure plate 4 closer to the mold box 2. If the distance is too small, move the pressure plate 4 away from the mold box 2. When the lower surfaces of both abutting parts 41 are in contact with the upper surfaces of the two elastic retaining strips 11, the adjustment is complete, and then tighten the locking screw 53. This design has a simple structure and is easy to operate.
[0051] For example, see Figure 5 and Figure 6 The movable block 52 extends along the X direction and includes a first movable block 522 and a second movable block 523. The first movable block 522 is disposed within a groove 51, and its thickness is the same as the depth of the groove 51. The second movable block 523 is fixedly connected below the first movable block 522, with its upper surface at least partially in contact with the lower surface of the connecting plate 3, and its end fixedly connected to the upper end of the pressure plate 4. This design ensures that the movable block 52 remains in contact with the connecting plate 3 at all times, and due to the friction between them, the movable block 52 will not move relative to the connecting plate 3 after locking.
[0052] Specifically, see Figure 7 The connecting plate 3 has an oblong hole 31 extending along the X direction, and the oblong hole 31 penetrates the connecting plate 3 along its thickness direction. (See also...) Figure 5 and Figure 6 The movable block 52 is provided with a threaded hole 521, and the locking screw 53 passes through the oblong hole 31 and is threadedly connected to the threaded hole 521. The length of the oblong hole 31 should not be set too large, so as to effectively control the range of adjustment of the pressure plate 4 spacing. Furthermore, the synergistic effect of the movable block 52, the slide 51, and the oblong hole 31 can improve the stability of the position adjustment of the movable block 52, avoid repeated adjustments by the operator, simplify the adjustment process, and improve adjustment efficiency.
[0053] This application does not limit the number of movable blocks 52. In one embodiment of this utility model, there is one movable block 52 and one locking screw 53. The movable block 52 is connected to the first end of a pressure plate 4, and the locking screw 53 is used to lock the position of the movable block 52. The upper end of the other pressure plate 4 is fixedly connected to the connecting plate 3. When adjusting the distance between the two pressure plates 4, the operator can only move the position of the pressure plate 4 connected to the movable block 52; the other pressure plate 4 remains fixed. In another embodiment of this utility model, see... Figure 5 There are two movable blocks 52 and two locking screws 53. The two movable blocks 52 are respectively connected to the first end of the two pressure plates 4, and the two locking screws 53 are used to lock the position of the two movable blocks 52. The design of two movable blocks 52 allows the operator to adjust the position of any one or both pressure plates 4 as needed, providing greater flexibility.
[0054] Specifically, the connecting plate 3, the two pressure plates 4, and the two moving blocks 52 are all made of carbon steel. Disassembly fixtures made of carbon steel are inexpensive and cost-effective. Furthermore, they possess sufficient hardness and strength to meet usage requirements.
[0055] When it is necessary to disassemble the mold box 2 on the base plate 1, the operator first loosens the two locking screws 53, then holds the connecting plate 3 with one hand and moves the two abutment parts 41 towards the two elastic retaining strips 11 respectively. Then, the operator visually judges whether the distance between the two abutment parts 41 matches the size of the mold box 2, and makes minor adjustments to the distance by sliding the moving block 52. When the lower surfaces of the two abutment parts 41 are in contact with the upper ends of the two elastic retaining strips 11, the operator tightens the two locking screws 53. The moving block 52 remains in its current position under the action of threaded connection and friction, and the distance adjustment of the disassembly fixture is completed.
[0056] Subsequently, the operator presses down on the two elastic retaining strips 11 along the Y direction. Under the pressure, the two elastic retaining strips 11 undergo elastic deformation. As the operator continues to press, the elastic retaining strips 11 disengage from the sides of the mold box 2, and the locking of the elastic retaining strips 11 onto the mold box 2 is released. The operator then uses their other hand to pull the mold box 2 away from the base plate 1 along its extension direction, and the mold box 2 is pulled away from the base plate 1, completing the disassembly of the mold box 2.
[0057] The disassembly fixture provided by this utility model has a simple structure and is easy to use. Only one person is needed to quickly disassemble the cigarette mold box, reducing the disassembly time and improving the disassembly efficiency. Furthermore, the distance between the two pressure plates can be adjusted by the adjustment mechanism, making it suitable for disassembling mold boxes of different sizes, thus having greater versatility.
[0058] 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.
