Description

Technical Field

[0001] This utility model relates to the field of tobacco pack conveying technology, specifically to a deviation correction and guiding device. Background Technology

[0002] The FT623 vertical blade slitting machine is a crucial piece of equipment for uniformly slitting open cigarette packs into three-blade, four-piece cigarette blocks. The equipment mainly consists of a belt conveyor, a pusher plate, a cutter, a discharge plate, and a baffle plate. The cigarette packs entering the equipment are pushed to the cutter by the pusher plate. The cutter has high requirements for the position of the cigarette pack. The deviation between the center line of the cigarette pack and the center line of the belt conveyor cannot exceed ±40mm, and the cigarette pack cannot be tilted excessively.

[0003] Utility model CN214454689U discloses an online automatic correction device for cigarette packs on a belt conveyor. The device includes a cigarette pack opening machine, a cigarette pack slitting machine, and a belt conveyor. The belt conveyor transports cigarette packs sequentially through the opening machine for opening and through the slitting machine for slitting. A cigarette pack correction guide device is installed on the belt conveyor between the opening and slitting machines. After being corrected by the correction guide device, the opened cigarette packs smoothly enter the slitting machine for slitting. This utility model, by installing a cigarette pack correction guide device on the belt conveyor before the slitting machine, can automatically correct cigarette packs that are off-center or tilted to the appropriate position, effectively preventing the common problem of the pusher plate jamming during the cigarette pack entry into the slitting machine, reducing manual intervention, and improving work efficiency.

[0004] However, the existing technology has the following shortcomings in use: 1. Two symmetrical cigarette pack guide plates are set above the conveyor belt motor. The two cigarette pack guide plates are close to the side and are fixed. Both ends of the two guide plates are fixed with guide ramps. When correcting the deviation, the cigarette packs will collide with the guide ramps under the transmission of the conveyor belt motor. After the collision, the cigarette packs are prone to deformation, which will affect the quality after subsequent slitting; 2. The two cigarette pack guide plates are connected to the frame on the conveyor belt by adjusting screws and adjusting nuts respectively. When it is necessary to adjust the distance between the two cigarette pack guide plates, it is only necessary to turn the adjusting bolts one by one. However, this adjustment method is prone to the problem that the space between the two cigarette pack guide plates is not centered after adjustment or the distance between the two is uneven. It is necessary to repeatedly turn the adjusting nuts to complete the distance adjustment, which has the defect of poor convenience in adjusting the distance between the two cigarette pack guide plates.

[0005] Therefore, this utility model provides a deviation correction and guidance device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a correction and guidance device to solve the problems mentioned in the background technology. This utility model has the function of buffering and guiding when correcting the tobacco pack, which can effectively avoid the problem of tobacco pack impact and deformation. It also has the advantage of being able to conveniently and quickly adjust the correction method according to the tobacco pack specifications.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a deviation correction and guiding device, including a belt conveyor, on which a frame and a transmission belt located within the frame are provided. A gantry frame located above the transmission belt is fixedly installed on the frame. Two deviation correction plates are provided inside the gantry frame. The tops of the two deviation correction plates are rotatably connected to the top of the gantry frame near both sides. A guide plate is elastically slidably connected to the middle of the top of the gantry frame. The adjacent ends of the two deviation correction plates are hinged to the guide plate via connecting rods.

[0008] Furthermore, the bottom of the gantry frame is welded with suspension shafts near both sides, and the top of the correction plate is welded with a positioning sleeve that is rotatably connected to the suspension shafts.

[0009] Furthermore, a guide sleeve is welded to the middle of the bottom of the crossbeam at the top of the portal frame. The guide sleeve is fitted outside the guide plate and the two slide together. A connecting shaft is fixedly installed near one end on the top of each of the two correction plates. The two sides of the guide plate are respectively hinged to the connecting shafts on the two correction plates via connecting rods.

[0010] Furthermore, a cantilever beam is welded to the middle of one side of the crossbeam, and a baffle is welded to the bottom of the cantilever beam. A baffle plate is fixedly sleeved on the outside of the guide plate, and a support spring is also sleeved on the guide plate between the baffle plate and the baffle plate.

[0011] Furthermore, one end of the guide plate is fixedly connected to a stop shaft opposite to the baffle, and an adjusting screw that is opposite to and coaxial with the stop shaft is screwed through the baffle.

[0012] Furthermore, an adjustment handle is welded to one end of the adjusting screw.

[0013] Furthermore, polished plates are bonded to the opposite sides of the two correction plates.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, two correction plates are installed above the conveyor belt. The two correction plates have the function of synchronously opposing and reversing elastic swing. Thus, when the conveyor belt carries the cigarette pack through the inner wall of the figure-eight shape formed by the two correction plates near the large end, the two correction plates will swing elastically to buffer the impact force on the cigarette pack, eliminating the problem of deformation of the cigarette pack caused by the impact.

[0016] In this invention, a guide plate is installed on the frame above the conveyor belt. The two sides of the guide plate are hinged to two correction plates respectively through connecting rods. Then, a screw is installed on the frame to adjust the one-way limit stroke of the guide plate. Therefore, the correction distance between the two correction plates can be accurately adjusted by turning the screw, which has the advantages of more accurate, faster and more convenient correction through distance adjustment.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a correction and guiding device, including a belt conveyor 1, a frame 11 and a transmission belt 12 located inside the frame 11 on the belt conveyor 1, a gantry frame 111 fixedly installed above the transmission belt 12 on the frame 11, and two correction plates 2 installed inside the gantry frame 111. When in use, a cigarette pack is placed on the transmission belt 12, and the cigarette pack is corrected by the correction plates 2 as it passes through the two correction plates 2 along with the transmission belt 12.

[0023] In this technical solution, the two straightening plates 2 form a V-shape. The tops of both straightening plates 2 are rotatably connected to the top of the portal frame 111 near the sides. Preferably, the bottom of the portal frame 111 is welded with suspension shafts 4 near the sides, and the top of the straightening plates 2 is welded with positioning sleeves 21 that are rotatably connected to the suspension shafts 4. When the two straightening plates 2 rotate, the angle between them changes. A guide plate 3 is elastically slidably connected to the middle of the top of the portal frame 111. The adjacent ends of the two straightening plates 2 are hinged to the guide plate 3 via connecting rods 9. When the guide plate 3 moves back and forth, it can control the two straightening plates 2 to swing synchronously and at the same angle towards each other and in opposite directions. The elastic sliding setting of the guide plate 3 allows the two straightening plates 2 to buffer the impact of the cigarette pack.

[0024] Specifically, a guide sleeve 11111 is welded to the middle of the bottom of the crossbeam 1111 at the top of the portal frame 111. The guide sleeve 11111 is fitted on the outside of the guide plate 3 and the two slide together. A connecting shaft 22 is fixedly installed near one end on the top of each of the two correction plates 2. The two sides of the guide plate 3 are hinged to the connecting shaft 22 on the two correction plates 2 respectively through the connecting rod 9. When the two correction plates 2 swing, the guide plate 3 can slide along the guide sleeve 11111 through the connecting rod 9.

[0025] Among them, a cantilever beam 5 is welded to the middle of one side of the crossbeam 1111. The cantilever beam 5 is perpendicular to the crossbeam 1111. A baffle 51 is welded to the bottom of the cantilever beam 5. The baffle 51 is close to the free end of the cantilever beam 5. A baffle plate 32 is fixedly sleeved on the outside of the guide plate 3. A support spring 6 is also sleeved on the guide plate 3 between the baffle plate 32 and the baffle 51. The support spring 6 applies elastic force to the guide plate 3 through the baffle plate 32.

[0026] In this embodiment, a stop shaft 33 opposite to the baffle 51 is fixedly connected to one end of the guide plate 3. An adjusting screw 7, which is opposite to and coaxial with the stop shaft 33, is screwed through the baffle 51. When the guide plate 3 slides towards the baffle 51, the support spring 6 is compressed. When the stop shaft 33 and the screw 7 abut against each other, the distance between the small ends of the figure-eight shape formed by the two correction plates 2 is fixed, and this distance is the correction distance. Therefore, the correction distance can be adjusted by turning a single adjusting screw 7 when correcting the deviation of cigarette packs of different specifications.

[0027] One end of the adjusting screw 7 is welded with an adjusting handle 71, which is an operating component for manually rotating the screw 7.

[0028] In this embodiment, polishing plates 8 are bonded to the opposite sides of the two correction plates 2. The polishing plates 8 are made of stainless steel and are polished on one side to reduce the friction between the cigarette pack and the stainless steel, making it easier for the cigarette pack to slide along the stainless steel plate.

[0029] Working principle: When in use, the cigarette pack is placed on the conveyor belt 12, and the cigarette pack is in an inclined state. The conveyor belt 12 rotates and carries the inclined cigarette pack towards the two correction plates 2. When the inclined cigarette pack contacts one of the opposite sides of the two correction plates 2, the contacted correction plate 2 will swing to meet the impact of the cigarette pack. Under the transmission of the connecting rod 9, the guide plate 3 slides and the support spring 6 is compressed. Thus, under the action of the support spring 6, the swing of the correction plate 2 can effectively buffer the impact force of the cigarette pack. After the two correction plates 2 swing, they guide the cigarette pack through. When the stop shaft 33 and the lead screw 7 abut, the minimum distance between the two correction plates 2 is the correction width. After the cigarette pack passes through the channel corresponding to this correction width, it is in a corrected state and is located in the middle of the conveyor belt 12, realizing the function of buffering and correcting the transmission of the cigarette pack.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
