Description

Technical Field

[0001] This invention relates to the field of packaging material conveying technology in the tobacco industry, and in particular to a carton paper swing guide device. Background Technology

[0002] like Figure 1 As shown, the existing YB611 carton packaging machine's carton paper suction device uses suction cups to pick up the bottommost carton paper from the carton paper magazine and sends it to the carton paper conveying channel. Two negative pressure suction belts 1 combined with a backing belt transport the paper downwards within the conveying channel. At the lower position of the conveying channel, the front end of the carton paper is already detached from the channel and in a free state. The rear end of the carton paper continues to be conveyed downwards by the suction belts 1 combined with two auxiliary pressure rollers 2, causing the front end of the carton to enter the narrow gap between the frame-type pre-folder 4 and the carton forming channel 5. After the carton paper is conveyed and falls onto the two paper receiving racks 3, the upper indentation A and lower indentation B of the carton sheet Ca should be aligned with the tops of the upper indentation plate A1 and lower indentation plate B1 of the frame-type pre-folder 4. During the descent of the carton paper, the upper pre-folder is in a stationary position. When both the cigarette pack and the carton paper reach the packaging position, the pusher pushes the cigarette pack toward the carton paper. At this time, the upper and lower pre-folders swing toward the frame-type pre-folder 4, and the carton is pre-folded in a "[" shape during the pusher's advance.

[0003] However, when the carton paper enters the narrow gap between the frame-type pre-folder 4 and the carton forming channel 5, if the carton paper is warped or not flat, the front end of the carton paper is very likely to collide with the frame-type pre-folder 4, causing the carton paper to block the narrow gap between the frame-type pre-folder 4 and the carton forming channel 5, which seriously affects the operating efficiency of the equipment.

[0004] Therefore, there is an urgent need for a carton paper swing guide device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a carton paper swing guide device that can guide the carton paper and prevent it from blocking the narrow gap between the frame pre-folder and the carton forming channel.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The two adjusting rods are respectively threaded to one end of the intermediate rod.

[0018] Optionally, locking nuts are provided at both ends of the intermediate rod.

[0019] Optionally, the connecting assembly includes a swing arm and a connecting block. The swing arm has a fixing groove, and the swing shaft of the upper pre-folder can extend into the fixing groove. The connecting block is detachably connected to the swing arm, and the connecting block and the swing arm can clamp the swing shaft of the upper pre-folder.

[0020] Optionally, a connecting portion is provided at the end of the swing arm away from the fixed groove.

[0021] The beneficial effects of this invention are:

[0022] The present invention provides a carton paper swing guide device, wherein the first fixed seat and the second fixed seat are respectively fixed on the machine wall panel and the outer wall panel of the carton conveying device. The power is provided by the swing shaft of the upper pre-folder. Therefore, the device always moves synchronously with the upper pre-folder. When the carton paper is conveyed downward, the upper pre-folder swings backward to make room for the carton to descend. At the same time, the swing shaft of the upper pre-folder drives the second swing bracket to swing through the connecting component, which in turn drives the guide component to swing towards the carton paper, thereby guiding the carton paper into the narrow gap between the frame-type pre-folder and the carton forming channel. After the carton paper is conveyed to the position, the upper pre-folder swings forward to pre-fold the carton paper. At the same time, the swing shaft of the upper pre-folder drives the second swing bracket to swing through the connecting component, which in turn drives the guide component to move away from the carton paper, thereby making room for the carton paper to be folded.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 2 to 5 As shown, this embodiment provides a carton paper swing guide device, including a first swing bracket 100, a second swing bracket 200, a guide assembly, and a connecting assembly. One end of the first swing bracket 100 is rotatably connected to a first fixed seat 300, and one end of the second swing bracket 200 is rotatably connected to a second fixed seat 700. The first fixed seat 300 and the second fixed seat 700 can be fixed to the machine wall panel and the outer wall panel of the carton conveying device, respectively. One end of the guide assembly is connected to the end of the first swing bracket 100 away from the first fixed seat 300, and the other end of the guide assembly is connected to the end of the second swing bracket 200 away from the second fixed seat 700. One end of the connecting assembly is connected to the swing shaft of the upper pre-folder, and the other end of the connecting assembly is drively connected to the second swing bracket 200. Exemplarily, both the first fixed seat 300 and the second fixed seat 700 are provided with several circular holes, through which bolts, pins, or screws can pass to connect to the machine wall panel or the outer wall panel of the carton conveying device, providing positioning and support for the entire carton paper swing guide device.

[0039] The carton paper swing guide device provided in this embodiment is applicable to rigid carton packaging equipment such as YB611 / YB611A / BV. The first fixed seat 300 and the second fixed seat 700 are respectively fixed on the machine wall panel and the wall panel outside the carton conveying device. The power is provided by the swing shaft of the upper pre-folder. Therefore, the device always moves synchronously with the upper pre-folder. When the carton paper is conveyed downward, the upper pre-folder swings backward to make room for the carton to descend. At the same time, the swing shaft of the upper pre-folder drives the second swing bracket 200 to swing through the connecting component, which in turn drives the guide component to swing towards the carton paper, thereby guiding the carton paper into the narrow gap between the frame-type pre-folder and the carton forming channel. After the carton paper is conveyed to the position, the upper pre-folder swings forward to pre-fold the carton paper. At the same time, the swing shaft of the upper pre-folder drives the second swing bracket 200 to swing through the connecting component, which in turn drives the guide component away from the carton paper, thereby making room for the carton paper to be folded.

[0040] For example, the first swing bracket 100 is provided with a first hole, and the second swing bracket 200 is provided with a second hole. Rolling bearings are provided in the first hole and the second hole. The ball bearing in the first hole is loosely fitted on the pin provided on the first fixed seat 300, and the ball bearing in the second hole is loosely fitted on the pin provided on the second fixed seat 700.

[0041] Optionally, the carton paper swing guide device provided in this embodiment further includes a connecting rod assembly 600. One end of the connecting rod assembly 600 is rotatably connected to the connecting assembly, and the other end of the connecting rod assembly 600 is rotatably connected to the second swing bracket 200. The length of the connecting rod assembly 600 is adjustable. The connecting assembly is driven to the second swing bracket 200 through the connecting rod assembly 600, and the length of the connecting rod assembly 600 is adjustable. By adjusting the length of the connecting rod assembly 600, the swing amplitude of the second swing bracket 200 driven by the connecting assembly can be changed, thereby adjusting the swing stroke of the guide assembly.

[0042] In some specific embodiments, the linkage assembly 600 includes a central rod 601 and two adjusting rods 602. The central rod 601 has internal threads with opposite directions at both ends. The two adjusting rods 602 have external threads with opposite directions that engage with the internal threads. Each adjusting rod 602 is threadedly connected to one end of the central rod 601. In use, the end of one adjusting rod 602 away from the central rod 601 is rotatably connected to the connecting assembly, and the end of the other adjusting rod 602 away from the central rod 601 is rotatably connected to the second swing bracket 200. Through the engagement of the external and internal threads, rotating the central rod 601 allows the two adjusting rods 602 to extend and retract synchronously, thereby adjusting the length of the linkage assembly 600. For example, the central rod 601 has a regular hexagonal cross-section to facilitate rotation.

[0043] Optionally, locking nuts 603 are provided at both ends of the intermediate rod 601. The locking nuts 603 can lock the intermediate rod 601 and the two adjusting rods 602, ensuring the stability of the connecting rod assembly 600. Loosening the locking nuts 603 and rotating the intermediate rod 601 can change the length of the adjustable connecting rod assembly 600. The ends of the two adjusting rods 602 away from the intermediate rod 601 are provided with connecting holes, and spherical bearings are installed in the connecting holes. The spherical bearing of one adjusting rod 602 is connected to the connecting assembly through a pin, and the spherical bearing of the other adjusting rod 602 is connected to the second swing bracket 200 through a pin. The pins are fixed on the connecting assembly and the second swing bracket 200 respectively, and the ends of the two adjusting rods 602 away from the intermediate rod 601 can rotate around the pins.

[0044] In some specific embodiments, the guiding assembly includes a guide block mounting base 800 and a carton guide block 900. One end of the guide block mounting base 800 is connected to the end of the first swing bracket 100 away from the first fixed base 300, and the other end of the guide block mounting base 800 is connected to the end of the second swing bracket 200 away from the second fixed base 700. The carton guide block 900 is detachably mounted on the guide block mounting base 800, facilitating its assembly and disassembly. The carton guide block 900 has a receiving groove 901 through which the guide block mounting base 800 passes, allowing the carton guide block 900 to slide relative to the guide block mounting base 800. This structure facilitates the adjustment of the position of the carton guide block 900. Both ends of the guide block mounting base 800 can be fixedly connected to the first swing bracket 100 and the second swing bracket 200 respectively using screws.

[0045] Optionally, the guide block mounting base 800 has several through holes 801, and the carton guide block 900 has threaded holes 902. Screws pass through the through holes 801 and are threaded into the threaded holes 902, thereby fixing the carton guide block 900 onto the guide block mounting base 800 and facilitating disassembly and assembly. In a preferred embodiment, the end of the carton guide block 900 facing away from the guide block mounting base 800 is provided with a protrusion 903. The protrusion 903 of the carton guide block 900 can reduce the contact area between the carton guide block 900 and the carton paper and ensure that the carton paper passes smoothly through the carton paper swing guide device.

[0046] In some specific embodiments, the connecting assembly includes a swing arm 400 and a connecting block 500. The swing arm 400 has a fixing groove 401 into which the swing shaft of the upper pre-folder can extend. The connecting block 500 is detachably connected to the swing arm 400, and the connecting block 500 and the swing arm 400 can clamp the swing shaft of the upper pre-folder. In use, the swing shaft of the upper pre-folder is inserted into the fixing groove 401, and then the connecting block 500 is installed on the swing arm 400, clamping the swing shaft of the upper pre-folder. For example, when the connecting block 500 is installed on the swing arm 400, the connecting block 500 and the fixing groove 401 are D-shaped, and the connection between the swing shaft of the upper pre-folder and the connecting assembly is D-shaped to make the connecting assembly more securely fixed to the swing shaft of the upper pre-folder. The swing arm 400 can be fixed to the swing shaft of the upper pre-folder by screws using the connecting block 500. Preferably, a connecting part 402 is provided at the end of the swing arm 400 away from the fixed groove 401, and one end of the connecting rod assembly 600 is rotatably connected to the connecting part 402 of the swing arm 400 in the connecting assembly, so as to avoid interference between the swing arm 400 and the connecting rod assembly 600 during the swinging process, which would affect normal use.

[0047] In this embodiment, the carton paper swing guide device is used such that the first fixed seat 300 and the second fixed seat 700 are respectively fixed on the machine wall panel and the wall panel outside the carton conveying device. The swing shaft of the upper pre-folder extends into the fixed groove 401. The connecting block 500 is installed on the swing rod 400. The connecting block 500 and the swing rod 400 clamp the swing shaft of the upper pre-folder. Loosen the locking nut 603 and rotate the intermediate rod 601 to adjust the length of the connecting rod assembly 600 to a suitable length. As the carton paper is conveyed downwards, the upper pre-folder swings backwards to create a descending channel for the carton. Simultaneously, the swing shaft of the upper pre-folder drives the connecting rod assembly 600 via the swing rod 400. The connecting rod assembly 600 drives the second swing bracket 200 to swing, which in turn drives the carton guide block 900 on the guide block mounting seat 800 to swing towards the carton paper. The protrusion 903 of the carton guide block 900 guides the carton paper into the narrow gap between the frame-type pre-folder and the carton forming channel. After the carton paper is conveyed to the correct position, the upper pre-folder swings forward to pre-fold the carton paper. At the same time, the swing shaft of the upper pre-folder drives the connecting rod assembly 600 via the swing rod 400. The connecting rod assembly 600 drives the second swing bracket 200 to swing, which in turn drives the carton guide block 900 on the guide block mounting seat 800 away from the carton paper, thus creating the space required for folding the carton paper.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
