Description

Technical Field

[0001] The utility model relates to the technical field of cigarette box packaging, in particular to an adjustable pad roller mechanism used for line cutting of cigarette boxes. Background Art

[0002] The YB95 cellophane wrapping machine, an auxiliary machine for the ZB45 rigid carton packaging unit, is primarily used to wrap cigarette cartons with cellophane paper. The cellophane paper supply is one of the machine's primary functions, conveying the cellophane paper with a drawstring attached to it to the packaging position, where it awaits packing. The machine primarily includes cellophane wrapping, drawstring unwinding and convergence, drawstring cutting, and cigarette carton conveying.

[0003] The cutting of the pull line is completed by a "U"-shaped cutter 1 and a traditional knife pad roller 4. It can cut a "U"-shaped pull head at the end of the pull line of the transparent paper, making it convenient for consumers to easily remove the transparent paper by pulling the pull head, thereby quickly taking out the product. Figure 1 As shown, in a conventional wire drawing cutting device, a cutter 1 is mounted on a first mounting seat 2, which is fixed to a first rotating shaft 3 via a locking screw. This allows the first mounting seat 2 to rotate clockwise along with the first rotating shaft 3, thereby moving the cutter 1 to the wire drawing cutting position. A conventional knife shim roller 4 is screwed to a second mounting seat 5, which is fixed to a second rotating shaft 6 via a bolt and key, allowing it to rotate counterclockwise along with the second rotating shaft 6.

[0004] The operating principle of a conventional wire-drawing cutting device is as follows: the first rotating shaft 3 and the second rotating shaft 6 rotate synchronously and continuously, respectively driving the cutter 1 and the conventional blade pad roller 4. After the wire-drawing device is combined with the transparent paper and attached, it is transported from right to left along the paper guide 7 between the working surfaces of the cutter 1 and the conventional blade pad roller 4. The lower part of the wire-drawing device is supported by the working surface of the conventional blade pad roller 4, while the upper part of the wire-drawing device is cut by the cutter 1, achieving a U-shaped cut of the wire-drawing device. Due to the limitations of the cutting principle and structure of the cutter 1 and the conventional blade pad roller 4 in such conventional wire-drawing cutting devices, the following problems exist:

[0005] (1) Traditional knife pad rollers are prone to wear. Since the position of the traditional knife pad roller corresponding to the cutter is always the same part of the working surface, after a certain period of use, obvious cutting marks will appear on the working surface of the traditional knife pad roller. Moreover, the cutting marks will expand and deepen with the extension of the running time, which accelerates the wear of the cutter, and then leads to quality problems such as uneven wire cutting or misaligned cutting.

[0006] (2) Frequent replacement of cutters. If the wire cutting quality is found to be unsatisfactory, the cutter must be replaced. When the new cutter works with the traditional cutter pad roller with existing cutting marks, the cutter wears out faster due to the cutting marks, resulting in a significant reduction in the service life. According to statistics, the average service life of the cutter is one month, and the shortest is one week.

[0007] (3) Although the tangent part can be replaced by replacing the traditional knife pad roller or rotating the traditional knife pad roller and changing the working surface, the traditional knife pad roller is located inside the machine below the two paper guides, the installation operation line of sight is limited, and the screw installation is time-consuming and extremely inconvenient; on the other hand, since the tangent part of the traditional knife pad roller is adjusted, the position of the cutter needs to be adjusted synchronously to ensure that the working surface of the traditional knife pad roller can be tangent to the cutter, which has the problem of great difficulty in adjustment and the need for repeated adjustments many times to achieve good cutting. Utility Model Content

[0008] The purpose of the present utility model is to provide an adjustable knife pad roller mechanism for the existing wire-drawing cutting device, which comprises an eccentric knife pad roller and an eccentric knife pad roller; the two ends of the support are detachably fixed to the paper guide; the eccentric knife pad roller is arranged below the first mounting seat; the eccentric knife pad roller is connected to the support by an eccentric shaft, and can be rotated by the cutter, so that the working surface of the eccentric knife pad roller and the cutting edge of the cutter are adapted to be tangent when in contact.

[0009] Due to the traditional cutting device, when the cutter rotates to be tangent to the traditional knife pad roller to achieve cutting, the distance between the cutter edge and the working surface of the traditional knife pad roller shows a process of gradually decreasing → tangent → gradually increasing as the cutter rotates. If the distance between the first rotating shaft and the second rotating shaft is fixed, the force exerted on the traditional knife pad roller by the cutter in this process shows a trend of gradually increasing → maximum → gradually decreasing. The utility model rotates the eccentric knife pad roller, and the eccentric knife pad roller rotates in coordination with the rotation of the cutter, so that the working surface farther from the eccentric shaft gradually rotates to the working surface closer to the eccentric shaft, and at the same time becomes tangent to the cutter, it compensates for the distance change during the rotation of the cutter, and avoids the difficulty in adjusting the position of the traditional knife pad roller, which leads to the minimum distance. The eccentric knife pad roller is used for cutting, which can effectively prevent the eccentric knife from wearing out and causing the eccentric knife pad roller to wear out.

[0010] Preferably, the adjustable pad roller mechanism for cutting cigarette boxes with thread pulling described in the present invention comprises an eccentric shaft comprising an axially arranged first supporting section, a second supporting section, and a third supporting section; the first supporting section and the third supporting section are both axially connected to the support; the eccentric knife pad roller is fixed to the second supporting section via a bearing.

[0011] As a preferred solution of the present invention, by setting up multiple supporting sections, the first supporting section and the third supporting section are only used to connect the support, and the second supporting section is used to connect the eccentric knife pad roller, so that the connection section and position of the eccentric knife pad roller can be set, which is beneficial for providing a position reference when subsequently adjusting the position of the eccentric knife pad roller, saving maintenance and installation time, and further improving the performance of the device.

[0012] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with thread pulling described in the present invention, the eccentric shaft also includes a fourth support segment arranged outside the first support segment, and the fourth support segment is in the shape of a quadrangular prism; the outer side wall of the third support segment is provided with an external thread.

[0013] As a preferred solution of the present invention, a hexagonal prism-shaped fourth supporting segment is provided, and an external thread is provided on the outer side wall of the third supporting segment. When installing or disassembling the eccentric shaft, the eccentric shaft can be easily twisted or axially screwed in and out by a wrench, which not only can adjust the position of the eccentric shaft, and then adjust the position of the eccentric knife pad roller, but also can adjust it conveniently and labor-savingly, reducing the difficulty of adjustment and enhancing the convenience of adjustment.

[0014] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with string cutting according to the present invention, the outer diameter of the first supporting section is greater than the outer diameter of the third supporting section.

[0015] As a preferred solution of the present invention, by setting the outer diameter of the first supporting section to be larger than the outer diameter of the third supporting section, and correspondingly opening a large screw hole and a small screw hole corresponding to the first supporting section and the third supporting section respectively on the support, the eccentric shaft can only pass through the large screw hole first and then pass through the small screw hole, avoiding the risk of the eccentric shaft falling due to the nut falling off or passing through too far when the nut is not installed, thereby improving the installation convenience and ease of use of the device.

[0016] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with a string according to the present invention, the outer diameter of the second supporting section gradually decreases from the first supporting section to the third supporting section.

[0017] As a preferred solution of the present invention, on the basis of setting the first supporting section and the second supporting section with different outer diameters, the second supporting section is set as a structure with an outer diameter gradually changing along the axial direction, so that the eccentric knife pad roller can be connected to the position of the third supporting section with a bearing having different outer diameters, or the position of the eccentric knife pad roller can be axially adjusted, so that the set distance between the working surface of the eccentric knife pad roller and the cutter can be adaptively adjusted, and the centering error between the cutter and the eccentric shaft can be compensated, effectively solving the problem of difficulty in adjustment caused by the non-parallelism between the working surface of the cutter and the traditional knife pad roller; further enhancing the adaptability and adjustability of the device, so that the set distance between the working surface of the eccentric knife pad roller and the cutter can be fine-tuned or further optimized, further reducing the chance of the eccentric knife pad roller being worn due to cutting marks, and extending the service life of the eccentric knife pad roller.

[0018] Preferably, the adjustable pad roller mechanism for cutting cigarette boxes by pulling the thread described in the present invention is provided with a first strip hole in the middle of the support; the length of the first strip hole is longer than the outer diameter of the eccentric knife pad roller; the width of the first strip hole is adapted to the thickness of the eccentric knife pad roller, so that the eccentric knife pad roller can be installed in the first strip hole.

[0019] As a preferred solution of the present invention, by setting a first strip hole, the eccentric knife pad roller can be adaptively installed in the first strip hole, so that the two side walls of the first strip hole form eccentric knife pad roller bearing pads, thereby enhancing the balance of force on the eccentric knife pad roller support, avoiding the displacement of the eccentric knife pad roller as it rotates, and further enhancing the stability of the device.

[0020] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with thread pulling described in the present invention, the support is used to connect the two ends of the paper guide paper and is respectively provided with a second strip hole and a third strip hole; the long sides of the second strip hole and the third strip hole are both parallel to the axial direction of the eccentric shaft; the second strip hole and the third strip hole are both used to pass through fixing screws.

[0021] As a preferred solution of the present invention, by setting the second strip hole and the third strip hole, the fixing screw can be moved along the long side direction and then tightened to achieve fixing one end of the support at different positions of the knife paper board, which is convenient for adjusting and setting the lateral position of the two ends of the support, that is, facilitating the lateral adjustment of the overall position of the eccentric knife pad roller, further enhancing the adjustability of the device, and thus improving the applicability of the device.

[0022] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with a drawing line described in the present invention, there is a thickness difference between the two ends of the support used to connect the paper guide.

[0023] As a preferred solution of the present invention, by setting a support with a thickness difference at both ends, the height of the two ends of the support can be adjusted by moving the position of the support, and then the vertical height of the support and the eccentric knife pad roller can be further adjusted, further enhancing the adjustability of the device and improving the applicability of the device.

[0024] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with thread cutting described in the present invention, the upper surface of a section of the support provided with the second strip hole and / or a section of the third strip hole is a stepped surface lower in height than the middle portion of the support.

[0025] As a preferred solution of the present invention, the horizontal surface of the stepped surface can be embedded in the lower part of the paper guide plate, and the vertical surface of the stepped surface can be pressed against the side of the knife paper plate, thereby preventing the support from moving horizontally due to the force of the eccentric knife pad roller during the rotation of the cutter, thereby further enhancing the stability of the device and improving production safety.

[0026] Preferably, in the adjustable pad roller mechanism for cutting cigarette boxes with a string, the support is laterally bent in an L-shape, so that the second strip hole and the third strip hole are laterally staggered relative to the central axis.

[0027] As a preferred solution of the present invention, the support is set to be lateral L-shaped, so that the second strip hole and the third strip hole are laterally offset relative to the central axis. For example, since the second strip hole is on the lateral side of the L-shape, it is farther away from the central axis. During the installation of the support, it can be laterally adjusted to a longer distance range according to the cutter seat and the cutter position, further improving the adjustable adaptability of the device and improving the performance of the device.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The eccentric knife pad roller rotates and cooperates with the cutter to rotate, so that the working surface farther from the eccentric shaft gradually rotates to the working surface closer to the eccentric shaft, and at the same time, it is tangent to the cutter and compensates for the spacing change during the rotation of the cutter. This avoids the traditional knife pad roller position being difficult to adjust, resulting in the working surface being subjected to excessive force from the cutter when the spacing is minimum, resulting in deep cutting marks, and also avoids the situation where the force is too small and the cutting cannot be in place. This reduces the probability of the eccentric knife pad roller being worn due to cutting marks, extends the service life of the eccentric knife pad roller, improves the quality of wire cutting, and improves production efficiency.

[0030] 2. During the rotation process, the eccentric knife pad roller can replace the cutting position of the working surface by setting different speeds, so that the working surface tangent to the cutter can be multiple continuous parts, avoiding multiple cutting of the same position of the working surface, thereby avoiding the risk of deepening and expanding the cutting marks, reducing the damage rate of the cutter, and reducing the frequency of cutter replacement, thereby reducing production costs and improving production efficiency; improving the coordination between the cutter and the eccentric knife pad roller, and improving the overall performance of the device.

[0037] The present invention will be described in detail below with reference to the accompanying drawings.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Example 1:

[0040] like Figure 2 As shown, this embodiment discloses an adjustable pad roller mechanism for cutting cigarette boxes, referring to Figure 1As shown, it includes a support 8 and an eccentric knife pad roller 9; the two ends of the support 8 are detachably fixed to the paper guide 7; the eccentric knife pad roller 9 is arranged below the first mounting seat 2; the eccentric knife pad roller 9 is connected to the support 8 through the eccentric shaft 10, and can be driven by the cutter 1 to rotate, so that the working surface 91 of the eccentric knife pad roller 9 and the cutting edge of the cutter 1 are adapted to be tangent when in contact.

[0041] The working principle of the utility model is as follows: the eccentric knife pad roller 9 is installed in the support 8 through the eccentric shaft 10. The support 8 is installed under the left and right paper guides 7 through two locking screws. The cutter 1 is driven by the first knife seat to rotate close to the eccentric knife pad roller 9. As the cutter 1 rotates clockwise with the first rotating shaft 3 as the axis, and contacts the working surface 91 of the eccentric pad roller, the tangential friction force drives the eccentric knife pad roller 9 to rotate counterclockwise with the eccentric shaft 10 as the axis. The circle of the rotation trajectory of the cutter 1 and the circle of the rotation trajectory of the eccentric knife pad roller 9 form an outer circle tangent to each other. , so that the string on the transparent paper is cut when it passes through the working surface 91 of the eccentric knife pad roller 9, thereby realizing the cutting of the cigarette box string; by adjusting the axial position of the eccentric knife pad roller 9 on the eccentric shaft 10, or by adjusting the position of the support 8, the distance between the blade of the eccentric knife pad roller 9 and the cutter 1 can be adjusted, and then the cutting gap tangent to the outer circle can be adjusted. Compared with the traditional knife pad roller 4, the tangential matching degree of the eccentric knife pad roller 9 and the cutter 1 is higher after they are rotated separately, and the position of the eccentric knife pad roller 9 can be manually adjusted so that the cutting gap can be adjusted.

[0042] It should be noted that the adaptive tangency is understood as the circular trajectory of the cutting edge of the cutter 1 rotating around the first rotating shaft 3 to form a circle, and the motion trajectory of the working surface 91 of the eccentric knife pad roller 9 rotating around the eccentric shaft 10 is tangent at the outer edge; specifically, the eccentricity of the eccentric knife pad roller 9 described in the utility model can be adaptively set according to the thickness or hardness of the wire; it should be noted that the eccentricity refers to the fact that the center of the circle of the eccentric knife pad roller 9 and the axis of the eccentric shaft 10 do not coincide with each other but deviate from each other; specifically, for example, the eccentricity of the eccentric knife pad roller 9 is 0.5mm on the eccentric shaft 10, so that the distance between the working surface 91 of the eccentric knife pad roller 9 and the cutter 1 can have an adjustment range of 1mm.

[0043] Specifically, the traditional knife pad roller 4 is discarded. Since the second rotating shaft 6 and the second mounting seat 5 of the original traditional knife pad roller 4 still exist, the first rotating shaft 3 is the main transmission shaft of the equipment and cannot be disassembled, and the second mounting seat 5 is installed on the second rotating shaft 6, the dismantling workload is large. At the same time, there are many parts around it. Therefore, the spatial dimensions of the equipment's installation layout are limited. The hardness of the working surface of the eccentric knife pad roller 9 of the present invention is usually 60-64HRC, and it is not easy to have cutting marks from the cutter 1, and it has a long service life; the present invention allows the bearing to tilt at a certain angle on the eccentric shaft 10, and has the characteristic of compensating for centering errors, which can effectively solve the problem of difficulty in adjustment caused by the non-parallel working surfaces 91 of the cutter 1 and the traditional knife pad roller 4 in the traditional cutting device; in the present invention, the cutter 1 rotates one circle with the first rotating shaft 3, contacts the working surface 91 of the eccentric knife pad roller 9 once, and realizes one-time wire cutting; while cutting the wire, the cutter 1 also moves the eccentric knife pad roller 9 to rotate an angle. The angle that the eccentric knife pad roller 9 can rotate is related to the rotation speed of the cutter 1 and the flexibility of the bearing rolling element. Therefore, multiple parts on the working surface 91 of the eccentric knife pad roller 9 can become cutting places that cooperate with the cutter 1 for cutting. Compared with the traditional traditional knife pad roller 4, the service life and cutting effect are doubled.

[0044] Specifically, refer to Figure 3 As shown, the eccentric shaft 10 includes a first supporting section 101, a second supporting section 102, and a third supporting section 103 arranged axially; the first supporting section 101 and the third supporting section 103 are both axially connected to the support 8; the second supporting section 102 is connected to the eccentric knife pad roller 9 by a bearing. The first supporting section 101 is a large-hole supporting section, for example, the outer diameter of the first supporting section 101 is 11 mm, and the support 8 is matched with the 11 mm large hole to achieve one-side support of the eccentric knife pad roller 9. The second supporting section 102 is an assembly section, for example, its outer diameter is 10 mm and its length is 16 mm. Figure 4 As shown, gaskets 92 are provided on both sides of the eccentric knife pad roller 9; the third supporting segment 103 is a small hole supporting segment, for example, the outer diameter of the third supporting segment 103 is 6 mm, which cooperates with the small hole with an outer diameter of 6 mm of the support 8 to realize the support of the other side of the eccentric knife pad roller 9; the third supporting segment 103 can be provided with an M6 thread with a length of 6.2 mm, and the eccentric shaft 10 is positioned by assembling an M6 nut; the first supporting segment 101, the third supporting segment 103 and the fourth supporting segment 104 are coaxial, and the axis of the second supporting segment 102 deviates from the axis of the first supporting segment 101 and the third supporting segment 103 by 0.5 mm, thereby realizing the eccentric installation of the eccentric knife pad roller 9.

[0045] Specifically, refer to Figure 3As shown, the eccentric shaft 10 also includes a fourth supporting section 104, located outside the first supporting section 101. The fourth supporting section 104 is in the shape of a quadrangular prism. The outer wall of the third supporting section 103 is provided with external threads. The fourth supporting section 104 is an adjustment section. For example, the prism length of the fourth supporting section 104 is 4 mm, and the cross-sectional side length is 7 mm. Using a 7 mm wrench, the eccentric shaft 10 can be rotated to adjust the eccentric shim roller 9.

[0046] Specifically, refer to Figure 3 As shown, the outer diameter of the first supporting segment 101 is greater than the outer diameter of the third supporting segment 103 ; the outer diameter of the second supporting segment 102 gradually decreases from the first supporting segment 101 to the third supporting segment 103 .

[0047] Specifically, refer to Figure 5 As shown, a first strip hole 81 is provided in the middle of the support 8; the length of the first strip hole 81 is longer than the outer diameter of the eccentric knife pad roller 9; the width of the first strip hole 81 is adapted to the thickness of the eccentric knife pad roller 9, so that the eccentric knife pad roller 9 can be installed in the first strip hole 81; for example, a second strip hole 82 and a third strip hole 83 with a diameter of 6.5 mm are designed at both ends of the support 8, and the support 8 is connected and fixed to the lower plane of the paper guide 7 by using M6×20mm screws; for example, in the support 8 The first strip hole 81 with a center design radius of 8.1mm and a center distance of 40mm is used to assemble the eccentric knife pad roller 9 so that the eccentric knife pad roller 9 is effectively supported. The width of the first strip hole 81 is 16.2mm, the thickness of the eccentric knife pad roller 9 is 14mm, plus two gaskets 92 with a thickness of 1mm equal to 16mm, so that the width of the first strip hole 81 and the thickness of the eccentric knife pad roller 9 are adapted. The remaining 0.2mm can effectively reduce the difficulty of assembly caused by processing and other factors.

[0048] Specifically, the support 8 is used to connect the two ends of the paper guide 7, and a second strip hole 82 and a third strip hole 83 are respectively provided; the long sides of the second strip hole 82 and the third strip hole 83 are parallel to the axial direction of the eccentric shaft 10; the second strip hole 82 and the third strip hole 83 are both used to pass through the fixing screw; to meet the cutting of multiple specifications with different wire pulling positions, while adjusting the cutter 1 axially, it is also necessary to adjust the position of the eccentric knife pad roller 9 accordingly. To achieve this need, the second strip hole 82 of the support 8 is set to 17mm, and the M6×20mm locking screw is loosened. The locking screw can be moved along the long side of the second strip hole 82, and then it can have an adjustment range of 17mm, so that the eccentric knife pad roller 9 can be adjusted to be vertically aligned with the cutter 1 to meet the cutting requirements.

[0049] In this embodiment, specifically, the upper surface of a section of the second strip hole 82 and / or a section of the third strip hole 83 of the support 8 is provided with a stepped surface 84 which is lower than the middle height of the support 8; in order to ensure that the support 8 is moved parallel to each other during adjustment, such as Figure 1 or Figure 5 The upper surfaces of both ends of the support 8 are provided with a 20mm×2mm stepped surface 84, which can be embedded in the bottom of the paper guide 7 to ensure that the support 8 can move parallel to the second strip hole 82 and the third strip hole 83 when adjusted, thereby improving the cutting quality.

[0050] The support 8 of the present invention is laterally bent into an L-shape 85, so that the second strip hole 82 and the third strip hole 83 are laterally offset relative to the central axis; for example Figure 5 As shown, the outer shape of the support 8 is designed to be L-shaped and bent 85 along the side of the support 8, so that there is a 10mm offset between the second strip hole 82 and the third strip hole 83 in the horizontal direction. Such a design can make full use of the assembly space and has a 17mm lateral adjustment range with the second strip hole 82 and the third strip hole 83. It should be noted that the central axis is understood to pass through the support 8. Figure 5 The straight lines between the left and right ends and the center are not understood as specific components but as reference lines.

[0051] like Figure 5 As shown, two mounting holes are respectively provided on both side walls of the first strip hole 81 of the support 8. The larger first mounting hole 86 has a diameter of 11 mm, and the smaller second mounting hole 87 has a diameter of 6 mm. During installation, only a threaded fitting nut needs to be added to the small diameter end of the eccentric shaft 10 to achieve the positioning of the eccentric shaft 10. The structure is simple and reliable.

[0052] Specifically, such as Figure 5 and Figure 1 As shown, there is a thickness difference between the two ends of the support 8 used to connect the paper guide 7, so that the support 8 can be installed under the paper guide 7. The thicknesses of the second strip hole 82 and the second strip hole 82 are 16 mm and 10 mm respectively, which can not only adapt to the 6 mm height difference between the left paper guide 7 and the right paper cutter board, but also can further adapt to the installation and adjustment of the height of the eccentric knife pad roller 9, thereby reducing the difficulty of installation.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
