Abstract
Description
Technical Field
[0001] This application relates to the field of cigarette production equipment technology, and in particular to an aluminum foil core rejection mechanism. Background Technology
[0002] In the cigarette manufacturing and packaging process, aluminum foil is used to wrap cigarettes. The aluminum foil is in roll form with a core in the center. The aluminum foil is wound around the core, and the packaging equipment is equipped with a core locking shaft. The entire roll of aluminum foil is placed on the locking shaft, which tightens to fix the core. When the current aluminum foil is used up, it needs to be replaced. The locking shaft is released, the empty core is released, and the operator starts the automatic feeding device to roll a new aluminum foil onto the locking shaft. Then the locking shaft tightens again to limit the tension of the new aluminum foil roll's core. In actual operation, after the current aluminum foil roll is used up and the tensioning shaft releases the empty core, the operator sometimes forgets to remove the empty core before starting the automatic feeding device, causing feeding interference. Utility Model Content
[0003] The purpose of this application is to provide an aluminum foil core removal mechanism that can remove the core after the locking shaft releases it, thereby effectively solving the shortcomings of the prior art.
[0004] Therefore, this application provides an aluminum foil roll core rejection mechanism, including:
[0005] The base is used to mount the locking shaft;
[0006] A contact element is movably disposed on the base, and the contact element has a first position and a second position relative to the base;
[0007] An elastic element is disposed between the seat and the contact element, and the elastic element drives the contact element to change from a first position to a second position;
[0008] The second position of the contact element tends to move toward the locking shaft provided on the seat body relative to the first position.
[0009] In some possible implementations, the contact is an elongated member that can be movably inserted through the base, with one end of the contact extending out of the base on the side where the locking shaft is located.
[0010] In some possible implementations, the contact element is movably penetrating the seat body, the contact element has a first end and a second end, the first end of the contact element extends out of the side of the seat body on which the locking shaft is provided, the second end of the contact element extends out of the other side of the seat body, an elastic element is provided between the first end of the contact element and the seat body, and the second end of the contact element is provided with a limiting element to prevent the contact element from disengaging from the seat body.
[0011] In some possible implementations, the contact element is a long cylindrical rod structure, the elastic element is a spring sleeved on the contact element, the first end of the contact element is provided with a pressing part, one end of the spring abuts against the seat body, and the other end of the spring abuts against the pressing part.
[0012] In some possible implementations, the limiting element is a nut threaded onto the contact element.

[0018] According to the aluminum foil core rejection mechanism provided in the embodiments of this application, the base is used to install the locking shaft, and the contact member is disposed on the base. The contact member has a first position and a second position relative to the base. Under the elastic drive of the elastic member, the contact member tends to change from the first position to the second position. When the contact member is in the second position, it moves more toward the side of the base where the locking shaft is disposed. Then, when the locking shaft releases the aluminum foil core, under the elastic action of the elastic member, the contact member pushes the core and disengages from the locking shaft, thereby preventing interference with automatic feeding.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] like Figures 1-5 As shown, this application provides an aluminum foil core rejection mechanism, applied in cigarette packaging equipment in a cigarette factory. After cigarettes are manufactured, they need to be packaged into boxes, cartons, and cartons, which requires aluminum foil. The aluminum foil is in roll form with a core 90 at the center. The aluminum foil is wound around the core 90. The packaging equipment is equipped with a core 90 locking shaft 80. Driven by other air source equipment, the locking shaft 80 can tighten or loosen. An automatic feeding device can place the rolled aluminum foil onto the locking shaft 80. When the locking shaft 80 tightens, the aluminum foil is removed from the packaging equipment. The core 90 is tensioned and limited. After the aluminum foil is used up, it needs to be replaced. The locking shaft 80 is released from tension, and the operator removes the empty core 90 and then starts the automatic feeding device to replace it with a new roll of aluminum foil. However, in actual operation, the operator may occasionally forget to remove the empty aluminum foil before starting the automatic feeding device. In this case, the empty core 90 will interfere with the feeding. The aluminum foil core 90 rejection mechanism provided in this application aims to remove the core 90 and avoid interference with the automatic feeding due to operator omission.
[0026] The aluminum foil roll core 90 rejection mechanism includes a base 100, a contact element 200, and an elastic element 300. The base 100 is used to mount a locking shaft 80, which carries the aluminum foil. An automatic feeding device places the rolled aluminum foil onto the locking shaft 80, so that the locking shaft 80 passes through the aluminum foil roll core 90. The locking shaft 80 is cylindrical, with its axis horizontal. One end of the locking shaft 80 is connected to the base 100, and the other end faces away from the base 100. Extending in the direction of 0, the contact member 200 is movably disposed on the seat 100. The contact member 200 has a first position and a second position relative to the seat 100. The elastic member 300 is disposed between the seat 100 and the contact member 200. Under the elastic driving force of the elastic member 300, the contact member 200 tends to change from the first position to the second position. That is, when there is no external force, under the action of the elastic member 300, the contact member 200 is in the first position relative to the seat 100. Under the action of external force, the external force... The elastic force of the elastic element 300 allows the contact element 200 to switch from the second position to the first position. The second position of the contact element 200 tends to move towards the locking shaft 80 provided on the seat 100 relative to the first position. That is, taking the locking shaft 80 being located on the right side of the seat 100 as an example, when the contact element 200 switches from the first position to the second position, it moves from left to right; when the contact element 200 switches from the second position to the first position, it is... Moving from right to left, the contact 200 can contact one end of the aluminum foil core 90. When feeding the locking shaft 80, the core 90 can contact the contact 200 and push the contact 200 to the left. When the aluminum foil is consumed, the locking shaft 80 releases the empty core 90. Under the action of the elastic element 300, the core 90 can be automatically pushed to disengage from the locking shaft 80 without manual removal, thus ensuring the removal of the core 90 and avoiding interference with automatic feeding.
[0027] Preferably, the contact member 200 is an elongated component, movably passing through the seat 100. One end of the contact member 200 extends out of the seat 100 on the side where the locking shaft 80 is located. In one example, the contact member 200 can movably penetrate the seat 100. The contact member 200 has a first end and a second end. The first end of the contact member 200 extends out of the side of the seat 100 where the locking shaft 80 is located, and the second end of the contact member 200 extends out of the other side of the seat 100. An elastic member 300 is disposed between the first end of the contact member 200 and the seat 100. The second end of the contact member 200 is provided with a limiting member to prevent the contact member 200 from disengaging from the seat 100. In this embodiment, the contact member 200... The contact 200 is an elongated component with a certain length. The contact 200 can move through the seat 100 along its own length direction. Taking the locking shaft 80 located on the right side of the seat 100 as an example, the first end of the contact 200 extends out of the right side of the seat 100, and the second end of the contact 200 extends out of the left side of the seat 100. The elastic element 300 is located between the seat 100 and the first end of the contact 200. Under the elastic force of the elastic element 300, the contact 200 tends to move to the right. A limiting element is provided on the second end of the contact 200 to prevent the contact 200 from moving too far to the right and disengaging from the seat 100.
[0028] More preferably, the contact element 200 is a long cylindrical rod structure, the elastic element 300 is a spring sleeved on the contact element 200, the first end of the contact element 200 is provided with a pressing part 201, one end of the spring abuts against the seat 100, and the other end of the spring abuts against the pressing part 201. The limiting element is a nut 203 threaded onto the contact element 200, and the seat 100 is provided with a through hole for the contact element 200 to move through. In this embodiment, the contact element 200 is generally long cylindrical rod-shaped, and the elastic element 300 is preferably a spring. More preferably, the through hole is... A circular hole is formed, with its axis parallel to the axis of the locking shaft 80 on the base 100. The axis of the locking shaft 80 is horizontal, with its left end connected to the base 100 and its right end extending horizontally to the right. The through hole is a circular cross-section and extends horizontally through the base 100. A contact member 200 is movably inserted through the through hole. The right end of the contact member 200 is the first end, and the left end is the second end. The first end of the contact member 200 extends to the right out of the base 100. On the right side of 00, the second end of the contact 200 extends to the left side of the seat 100. A spring is sleeved on the portion of the contact 200 that extends to the right side of the seat 100. The abutment 201 is located on the first end of the contact 200. The size of the abutment 201 is larger than the size of the contact 200. The inner diameter of the spring is larger than the outer diameter of the contact 200. The inner diameter of the spring is smaller than the outer diameter of the abutment 201. The outer diameter of the spring is larger than the inner diameter of the through hole. The left end of the spring abuts against the right side of the seat 100, and the right end of the spring abuts against the abutment 201. Under the elastic force of the spring, the contact 200 is driven to move to the right. The second end of the contact 200 extends to the left side of the seat 100. A nut 203 is provided at the second end of the contact 200. The outer diameter of the nut 203 is larger than the inner diameter of the through hole. Under the action of the nut 203, the contact 200 is restricted from dislodging from the through hole to the right, thus achieving a limiting position. In this embodiment, the clamping part 201 can be a sleeve-type structure. The clamping part 201 can be screwed onto the first end of the contact 200, making the component installation more convenient.
[0029] More preferably, a force-applying part 202 is provided on the side of the abutment 201 away from the contact member 200. The force-applying part 202 is used to release from the core 90. The outer diameter of the force-applying part 202 is larger than the outer diameter of the abutment 201. In this embodiment, the force-applying part 202 has a circular plate-shaped structure. The force-applying part 202, the abutment 201 and the contact member 200 are coaxially connected. The contact member 200, the abutment 201 and the force-applying part 202 are connected in sequence to increase the contact area with the end of the core 90.
[0030] More preferably, there are multiple contact elements 200, and the number of elastic elements 300 is the same as the number of contact elements 200. The contact elements 200 and elastic elements 300 are arranged in pairs. The multiple contact elements 200 are arranged in a ring around the center line of the locking shaft 80. In the viewing direction parallel to the axis of the locking shaft 80, the contact elements 200 are located outside the locking shaft 80, and the multiple contact elements 200 are evenly spaced. In this way, a more uniform force can be applied to the core 90, the pushing force is greater, and it is beneficial for the core 90 to disengage from the locking shaft 80.
[0031] The relative displacement between the first and second positions of the contact member 200 is greater than the length of the locking shaft 80 on the seat 100. That is, when the contact member 200 moves from the first position to the second position, the pushing displacement generated on the core 90 is sufficient to disengage the core 90 from the locking shaft 80.
[0032] In practice, when the locking shaft 80 is unloaded, the contact 200 is in the second position under the elastic action of the elastic element 300. At this time, the limiting force of the nut 203 prevents the contact 200 from dislodging from the through hole to the right. When loading, the aluminum foil is loaded onto the locking shaft 80. The core 90 of the aluminum foil roll is wrapped around the locking shaft 80 to the left while resisting the elastic force of the elastic element 300 to push the contact 200 to the left. After the core 90 is completely wrapped around the locking shaft 80, the contact 200 is in the leftmost position, which is the first position. At this time, the force-applying part 202 on the contact 200 abuts against the roll. The core 90 is fed to the left end, and then the locking shaft 80 is tightened to limit and fix the core 90, thus completing the automatic feeding. After the aluminum foil is consumed, the locking shaft 80 is released from its tension, thereby releasing the core 90. At this time, the release of the core 90 by the locking shaft 80 can be instantaneous, so that the contact member 200 can instantly pop the core 90 to the right to disengage from the locking shaft 80, or the release of the core 90 by the locking shaft 80 can be slow, under the influence of friction, the contact member 200 gradually pushes the core 90 to the right until the core 90 is completely disengaged from the locking shaft 80.
