Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a turning auxiliary device and a packaging machine. Background Technology

[0002] After production, tobacco products need to be packaged before being sold on the market. Currently, GDX1 and X2 packaging machines are commonly used. When equipment debugging or repair is required, the handwheel needs to be manually rotated. Therefore, to avoid safety issues, a gear set and a return spring are installed inside the control box. During machine operation, the return spring disengages the main gear (connected to the machine's drive shaft) and the pinion (connected to the handwheel) to prevent the handwheel from rotating. When debugging is needed, the operator pulls away from the control box to compress the return spring and engage the large and small gears, allowing the handwheel to be rotated. However, due to the elastic force of the return spring and the large torque of the machine's drive shaft, the handwheel can usually only be rotated clockwise. Counterclockwise rotation causes the gear set to disengage, making reverse rotation impossible. This is extremely inconvenient and reduces debugging and repair efficiency.

[0003] Therefore, there is an urgent need for a turning assist device and a packaging machine to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a handwheel adjustment device that can effectively prevent the handwheel from springing back during manual adjustment, thereby preventing the gear set from disengaging and ensuring that the handwheel can be rotated in either clockwise or counterclockwise directions, thus improving the convenience and efficiency of handwheel adjustment.

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

[0006] A turning assist device for assisting in the debugging of a packaging machine, comprising:

[0007] A magnetic bracket is installed on the control box of the packaging machine;

[0008] A rope, one end of which is connected to the magnetic bracket;

[0009] A chuck is connected to the end of the rope away from the magnetic support, and the chuck has a slot. When the packaging machine is not being adjusted, the chuck can be attracted to the magnetic support. When the packaging machine needs to be adjusted, the handwheel is pulled away from the control box to remove the chuck from the magnetic support and engage it in the gap between the handwheel and the control box. The chuck is then engaged with the outer circumference of the rotating shaft through the slot.

[0010] Preferably, the width of the slot is greater than the diameter of the rotating shaft, so that the handwheel can drive the rotating shaft to rotate relative to the chuck.

[0011] Preferably, the slot has an arc-shaped portion.

[0012] Preferably, the chuck is provided with a limiting step along the thickness direction, and when the chuck is engaged with the gap, the side of the limiting step away from the rope can fit against the handwheel.

[0013] Preferably, the chuck is provided with a protrusion on the side opposite to the limiting step, and the magnetic bracket is provided with a card hole. When the chuck is attracted to the magnetic bracket, the protrusion can be correspondingly engaged into the card hole.

[0014] Preferably, the magnetic bracket is L-shaped so that it can be positioned at the corner of the control box; the magnetic bracket includes a first main body and a second main body connected to each other, and the card hole is located on the first main body.

[0015] Preferably, the magnetic bracket is detachably connected to the operating box.

[0016] Preferably, the second body is provided with a threaded hole, through which the locking member can pass to fix the magnetic bracket.

[0017] Preferably, the rope is a steel cable.

[0018] The purpose of this utility model is to provide a packaging machine that is easy to debug and maintain, can be put into use quickly, and ensures the reliability and continuity of operations.

[0019] To achieve this objective, the present invention adopts the following technical solution:

[0020] Packaging machines, including:

[0021] The control box contains a first gear, which is connected to the drive shaft.

[0022] A handwheel is located outside the control box. One end of the handwheel is connected to the rotating shaft, which passes through the side wall of the control box and has a second gear connected to one end inside the control box.

[0023] An elastic element is provided between the second gear and the inner sidewall of the operating box. The elastic force of the elastic element causes the handwheel to have a tendency to move towards the operating box.

[0024] The chuck of the handwheel auxiliary device is located on the control box. When not being adjusted, the chuck is attached to the magnetic bracket. When being adjusted, the chuck is engaged in the gap between the handwheel and the control box.

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

[0026] This utility model discloses a turning assist device. The turning assist device includes a magnetic bracket, a rope, and a chuck. The magnetic bracket is mounted on the control box of the packaging machine. One end of the rope is connected to the magnetic bracket. The chuck is connected to the end of the rope away from the magnetic bracket, and the chuck has a slot. When the packaging machine is not being adjusted, the chuck can be attracted to the magnetic bracket. When the packaging machine needs to be adjusted, the handwheel is pulled away from the control box, the chuck is removed from the magnetic bracket, and then inserted into the gap between the handwheel and the control box. The chuck is then engaged with the outer circumference of the rotating shaft through the slot. This device can prevent the handwheel from springing back during the adjustment process, thus ensuring that the handwheel can be rotated in either clockwise or counterclockwise directions, thereby improving the convenience and efficiency of turning the machine.

[0027] When the operator manually adjusts the packaging machine, the handwheel needs to be pulled outwards. At this time, a gap will be formed between the handwheel and the control box. The chuck is then removed and inserted into the gap. One side of the chuck abuts against the control box, and the other side contacts the handwheel, thus preventing the handwheel from springing back to its initial position. Therefore, the chuck can ensure that the first gear and the second gear do not disengage during the rotation process. This allows the operator to choose to rotate the handwheel clockwise or counterclockwise to meet the actual adjustment needs, ensuring not only the flexibility and convenience of operation but also improving the safety of rotation.

[0028] This utility model also discloses a packaging machine that is easy to debug and maintain, can be put into use quickly, and ensures the reliability and continuity of operations. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0043] To improve the production efficiency of finished tobacco products, packaging machines are typically used to package them. For example... Figure 1 As shown, the packaging machine 100 mainly includes an operation box 110, a handwheel 120, and an elastic element 160. The operation box 110 contains a first gear 140, which is connected to a drive shaft 170. The handwheel 120 is located outside the operation box 110, with one end connected to a rotating shaft 130. The rotating shaft 130 passes through the side wall of the operation box 110, and its end inside the operation box 110 is connected to a second gear 150. An elastic element 160 (reset spring) is positioned between the second gear 150 and the inner side wall of the operation box 110. The elastic force of the elastic element 160 causes the handwheel 120 to tend to move closer to the operation box 110. When the packaging machine 100 is operating, as... Figure 1 In the state shown, the first gear 140 is not engaged with the second gear 150. At this time, the drive shaft 170 will not drive the external handwheel 120 to rotate, ensuring the safety of operation.

[0044] However, when debugging or equipment malfunctions requiring repair, the operator manually pulls the handwheel 120 away from the control box 110. The handwheel 120 drives the second gear 150 to move via the rotating shaft 130, compressing the elastic element 160 and engaging the first gear 140 with the second gear 150. The operator then rotates the handwheel 120 to debug the equipment. However, the existing packaging machine 100 can only rotate the handwheel 120 clockwise. When rotating counterclockwise, due to the greater resistance of the drive shaft 170 and the elastic force of the elastic element 160 (the return spring has a greater elastic force under compression), the first gear 140 and the second gear 150 will disengage. This is not only dangerous to operate but also prevents further rotation, making operation extremely inconvenient and debugging inefficient.

[0045] To address this issue, this embodiment also provides a turning assist device for assisting in the debugging of the packaging machine 100, such as... Figures 2-4As shown, the device includes a magnetic support 10, a rope 20, and a chuck 30. The magnetic support 10 is mounted on the control box 110 of the packaging machine 100. One end of the rope 20 is connected to the magnetic support 10. The chuck 30 is connected to the end of the rope 20 away from the magnetic support 10, and the chuck 30 has a slot 31. When the packaging machine 100 is not being adjusted, the chuck 30 can be attracted to the magnetic support 10. When the packaging machine 100 needs to be adjusted, the handwheel 120 is pulled away from the control box 110 to remove the chuck 30 from the magnetic support 10. The chuck 30 is then inserted into the gap between the handwheel 120 and the control box 110, and the chuck 30 is correspondingly engaged with the outer periphery of the rotating shaft 130 through the slot 31.

[0046] When the operator manually adjusts the packaging machine 100, the handwheel 120 needs to be pulled outward. At this time, a gap will be formed between the handwheel 120 and the control box 110. Then, the chuck 30 is taken out and inserted into the gap. At this time, one side of the chuck 30 abuts against the control box 110, and the other side contacts the handwheel 120, thus preventing the handwheel 120 from being bounced back to the initial position. Therefore, the chuck 30 can ensure that the first gear 140 and the second gear 150 will not disengage during the rotation process. Thus, the operator can choose to rotate the handwheel 120 clockwise or counterclockwise to meet the actual adjustment requirements. This not only ensures the flexibility and convenience of operation, but also improves the safety of rotation.

[0047] Furthermore, during chuck rotation, the chuck 30 is connected to the magnetic bracket 10 via the rope 20. The magnetic bracket 10 is fixed to the control box 110. Therefore, during the rotation of the handwheel 120, the chuck 30 will not rotate with the shaft 130 under the pull of the rope 20, thus ensuring that it remains engaged in the gap and guaranteeing smooth chuck rotation. After chuck rotation, the chuck 30 can be directly attached to the magnetic bracket 10, which not only reduces space occupation but also improves the aesthetics of the structure.

[0048] like Figure 4 As shown, the packaging machine 100 provided in this embodiment further includes the aforementioned chuck auxiliary device on top of the original structure. Its magnetic support 10 is disposed in the operation box 110. When not undergoing debugging, the chuck 30 is attached to the magnetic support 10. During debugging, the chuck 30 engages in the gap between the handwheel 120 and the operation box 110. Therefore, the packaging machine 100, based on its original functions, improves the convenience of debugging and maintenance, enabling rapid deployment and ensuring the reliability and continuity of operations.

[0049] Specifically, such as Figure 2 and Figure 3As shown, the width of the slot 31 is greater than the diameter of the rotating shaft 130, so that the handwheel 120 can drive the rotating shaft 130 to rotate relative to the chuck 30. By setting the width of the slot 31 slightly larger than the diameter of the rotating shaft 130, a certain degree of movement is achieved when the chuck 30 and the rotating shaft 130 are engaged. Therefore, the friction between the rotating shaft 130 and the chuck 30 is relatively small when the shaft rotates. Combined with the tension of the rope 20, the chuck 30 can generate relative friction with the rotating shaft 130 without rotating with it, ensuring good operational performance.

[0050] It should be noted that the width of the slot 31 should be slightly larger than the diameter of the shaft 130. A large difference will cause excessive wobbling of the chuck 30, while a small difference will result in excessive friction, increasing the difficulty of turning the chuck. In this embodiment, the width of the slot 31 is 5mm-10mm wider than the diameter of the shaft 130. In other embodiments, the difference between the width of the slot 31 and the shaft 130 can be adjusted according to actual needs.

[0051] Furthermore, in this embodiment, the rope 20 is a steel cable. Steel cables not only bear sufficiently large tensile loads but also possess good flexibility, improving both the safety of the chuck and the ease of storage. In addition, in this embodiment, the chuck 30 is made of 45# steel, which is not only wear-resistant but also capable of withstanding significant pressure and loads, is low in cost, easy to process, and can be magnetically attracted.

[0052] In addition, such as Figure 3 As shown, the slot 31 has an arc-shaped portion 311. Since the outer periphery of the rotating shaft 130 is arc-shaped, and the slot 31 has an arc-shaped portion 311 at the end away from the opening, the arc-shaped portion 311 can match the outer periphery of the rotating shaft 130 during the locking process, which improves the stability of the locking and also improves the smoothness of the relative rotation between the rotating shaft 130 and the chuck 30.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, the chuck 30 has a limiting step 32 along its thickness direction. When the chuck 30 is engaged with the gap, the side of the limiting step 32 away from the rope 20 can fit against the handwheel 120. This arrangement allows the handwheel 120 to fit only against the plane of the limiting step 32 away from the rope 20, thereby reducing the amount of material above the limiting step 32. While meeting the thickness requirements of the chuck 30, it also saves costs and reduces weight.

[0054] In addition, such as Figure 2 and Figure 3As shown, the chuck 30 has a protrusion 33 on the side facing away from the limiting step 32, and the magnetic bracket 10 has a locking hole 13. When the chuck 30 is attracted to the magnetic bracket 10, the protrusion 33 can be locked into the locking hole 13. This design prevents the chuck 30 from detaching from the magnetic bracket 10 due to insufficient magnetic force when stored, thereby strengthening the stability of the connection between the chuck 30 and the magnetic bracket 10, and also makes it convenient to remove the chuck 30 when needed. Since the protrusion 33 is located on the side facing away from the limiting step 32, the handwheel 120 will not contact the protrusion 33 when the chuck 30 is placed in the gap, thus preventing the protrusion 33 from breaking or the handwheel 120 from being worn.

[0055] like Figure 2 and Figure 4 As shown, the magnetic bracket 10 is L-shaped to allow it to be positioned at the corner of the control box 110. The magnetic bracket 10 includes a first main body 11 and a second main body 12 connected to each other, with a locking hole 13 located on the first main body 11. This arrangement allows the magnetic bracket 10 to be installed at the corner between the top and side panels of the control box 110, improving space utilization and avoiding the need for excessive external structures, thus ensuring the neatness and aesthetics of the control box 110's exterior.

[0056] In addition, the first main body 11 is provided with a first rope hole 15, and the top of the chuck 30 is provided with a second rope hole 34. The two ends of the rope 20 are respectively connected and fixed to the magnetic bracket 10 and the chuck 30 through the first rope hole 15 and the second rope hole 34.

[0057] Furthermore, the magnetic bracket 10 is detachably connected to the control box 110. This detachable connection facilitates subsequent maintenance or replacement of the magnetic bracket 10, ensuring ease of maintenance.

[0058] Specifically, such as Figure 2 and Figure 4 As shown, the second body 12 is provided with a threaded hole 14, through which the locking member 40 can pass to fix the magnetic bracket 10. The threaded hole 14 on the second body 12 avoids the locking hole 13 of the first body 11, thereby improving the ease of installation; at the same time, the locking member 40 fixes the magnetic bracket 10 to the operation box 110 through the threaded hole 14, which is not only simple to operate, but also has a good locking effect.

[0059] Furthermore, in this embodiment, the locking element 40 is a bolt. Bolts are not only simple in structure but also inexpensive, which helps reduce manufacturing costs and installation difficulty. In other embodiments, screws, anchors, pins, etc., can be used instead of bolts, as long as a stable connection can be ensured. This embodiment does not impose any other limitations.

[0060] The following describes the operation procedure of the rotary head auxiliary device for assisting in the debugging of the packaging machine 100 in the embodiment, with reference to the accompanying drawings:

[0061] First, pull the handwheel 120 away from the control box 110 so that the second gear 150 compresses the elastic element 160 and meshes with the first gear 140.

[0062] Next, remove the chuck 30 from the magnetic bracket 10 and align the slot 31 with the rotating shaft 130 to engage the chuck 30 into the gap, so that the limiting step 32 engages with the handwheel 120. Depending on the actual situation, choose to rotate the handwheel 120 clockwise or counterclockwise to complete the debugging work.

[0063] Finally, remove the chuck 30, attach the protrusion 33 into the chuck hole 13, and let the magnetic bracket 10 hold the chuck 30 in place; the elastic force of the elastic element 160 causes the second gear 150 to disengage from the first gear 140, and the equipment can be put into normal operation.

[0064] In summary, the handwheel 120 can be effectively prevented from springing back by using the handwheel auxiliary device in this embodiment, and the handwheel 120 can be rotated in either clockwise or counterclockwise directions, which improves the convenience and efficiency of handwheel operation.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
