Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a splicer protection device and a paper splicer. Background Technology

[0002] In cigarette production, paper rolls are used to manufacture cigarette tubes. To ensure the continuity and consistency of cigarette production, most existing cigarette machines use a paper roll splicer for continuous feeding. The splicer mainly includes a splicing mechanism, a first drive roller, a second drive roller, and an accelerator (which contains an accelerating roller). The first and second drive rollers respectively transport old and new paper rolls. When the old paper roll is about to run out, the accelerating roller drives the new paper roll on the second drive roller to change speed, making the speeds of the old and new paper rolls consistent, facilitating the subsequent splicing mechanism to join the old and new paper rolls. However, for existing high-speed cigarette machines, the paper roll transmission speed is relatively fast, which may lead to problems such as tape breakage or splicing failure. Since the splicer is a moving component, its improvement space is limited, and it is difficult to install a conventional paper discharge mechanism. Some waste paper rolls may fall and get stuck in the accelerator, causing paper breakage or equipment shutdown. In addition, the fine paper scraps generated during the normal operation of the splicer can easily fall onto the splicer surface, increasing friction, causing wear on the accelerator, and accelerating equipment aging. Utility Model Content

[0003] The purpose of this invention is to provide a splicer protection device with a simple structure that can prevent waste paper from contacting the accelerator and improve the reliability of the paper splicer operation.

[0004] To achieve this objective, the present invention adopts the following technical solution: a splicer protection device, comprising a protective cover, the protective cover having a guide slope extending from the top of the protective cover to the bottom front side of the protective cover along its length direction, and bolt assembly holes being formed on the guide slope, the bolt assembly holes penetrating the protective cover along its length direction; wherein, the protective cover also has a cleaning air duct, the cleaning air duct having an air inlet and an air outlet communicating with each other, the air outlet being formed on the guide slope and located above the bolt assembly holes, and the air inlet being connected to an external air source.

[0005] Preferably, the splicer protection device further includes a controller and a sensor. The sensor is installed on the protective cover and located on one side of the guide slope. The sensor is used to detect whether there are foreign objects on the guide slope. The sensor and the air source are respectively connected to the controller in communication.

[0006] Preferably, the sensor is configured as a photoelectric sensor, and a reflector is provided on one side of the guide slope. The reflector extends along the normal of the guide slope, and the photoelectric sensor and the reflector are positioned correspondingly.

[0007] Preferably, the bolt assembly hole includes a slotted hole and a blind hole. The slotted hole is arranged along the width direction of the protective cover and penetrates the rear sidewall of the protective cover along the length direction of the protective cover. The blind hole penetrates the guide slope along the length direction of the protective cover and communicates with the slotted hole.

[0008] Preferably, the inner diameter of the air outlet is smaller than the inner diameter of the air inlet.

[0009] Preferably, a connector is provided at the air inlet.

[0010] Preferably, the protective cover and the connector are integrally molded parts.

[0011] Another objective of this invention is to provide a paper roll splicer that, through the isolation of a protective cover, prevents waste paper rolls and paper scraps from interfering with the operation of the accelerator, thereby improving splicing accuracy and equipment stability, and extending service life.

[0012] To achieve this objective, the present invention adopts the following technical solution: a paper roll splicer, including a feeding assembly, an accelerator, and the aforementioned splicer protection device. The feeding assembly is located above the accelerator, and the feeding assembly and the accelerator cooperate to transmit the paper rolls to be spliced. The protective cover is fixed above the accelerator and abuts against the top surface of the accelerator, and the guide slope is located between the feeding assembly and the accelerator.

[0013] Preferably, a guide roller is provided between the feeding assembly and the accelerator. The guide roller is located on one side of the protective cover, and the paper roll is pressed tightly against the surface of the guide roller. A baffle is provided on the side of the guide slope near the guide roller, and the baffle extends upward along the normal direction of the guide slope.

[0014] Preferably, the baffle has a clearance portion on the side opposite to the guide slope, and the clearance portion is used to avoid the guide roller.

[0015] The beneficial effects of this invention are as follows: Before using the splicer, the protective cover is installed above the accelerator. When problems such as tape breakage or splicing failure occur in the cigarette rolling machine, the waste paper will fall onto the guide slope of the protective cover, and then fall from the front of the splicer under the guidance of the guide slope. This prevents the waste paper from getting stuck in the accelerator, causing paper breakage or equipment shutdown, effectively improving splicing accuracy and equipment stability. When the waste paper accumulates on the guide slope, the air outlet of the cleaning duct can blow the waste paper off the guide slope, achieving self-cleaning of the protective cover, reducing manual intervention, and effectively improving the utilization efficiency of the protective cover.

[0016] This utility model also provides a paper roll splicer, which guides waste paper rolls to fall through a protective cover while the cover abuts against the top surface of the accelerator, thus preventing fine paper scraps from falling onto the splicer surface, optimizing paper scrap management, reducing frictional wear on the splicer, and extending the service life of the paper roll splicer.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] In the description of this embodiment, the terms "upper," "lower," "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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0025] Reference Figures 1 to 3 As shown, a splicer protection device according to an embodiment of this application includes a protective cover 100. The protective cover 100 has a guide slope 110. Along the length direction of the protective cover 100, the guide slope 110 extends from the top of the protective cover 100 to the bottom of the front side of the protective cover 100. The ratio of the length of the guide slope 110 to the total length of the protective cover 100 is greater than or equal to 60%. At this time, the longitudinal cross-section of the protective cover 100 is trapezoidal. A bolt mounting hole 120 is provided on the guide slope 110. The bolt mounting hole 120 is located at the bottom of the protective cover 100 and penetrates the protective cover 100 along its length. The protective cover 100 also has a cleaning air duct 130, which has an interconnected air inlet and air outlet. The air outlet is located on the guide slope 110 and above the bolt mounting hole 120, while the air inlet is connected to an external air source. Alternatively, the external air source can be an air pump that is set up independently or installed in the cigarette machine, or it can be a compressed air assembly in the workshop, which will not be described in detail here.

[0026] Understandably, before using the splicer, the protective cover 100 is installed above the accelerator. When the cigarette machine experiences problems such as tape breakage or splicing failure, the waste paper will fall onto the guide slope 110 of the protective cover 100, and then fall from the front of the splicer under the guidance of the guide slope 110. This prevents the waste paper from getting stuck in the accelerator, causing paper breakage or equipment shutdown, effectively improving splicing accuracy and equipment stability. When waste paper accumulates on the guide slope 110, the air outlet of the cleaning duct 130 can blow air out, blowing the waste paper off the guide slope 110, achieving self-cleaning of the protective cover, reducing manual intervention, and effectively improving the efficiency of the protective cover's use.

[0027] Furthermore, the inner diameter of the air outlet is smaller than the inner diameter of the air inlet. Specifically, the cleaning air duct 130 is formed by connecting a first air duct and a second air duct that are perpendicular to each other. One end of the first air duct passes through the side wall of the protective cover 100 to form an air inlet, and one end of the second air duct is connected to the other end of the first air duct. The other end of the second air duct passes through the guide slope 110 to form an air outlet. The inner diameter of the second air duct is smaller than the inner diameter of the first air duct.

[0028] Designing the inner diameter of the air outlet to be smaller than that of the air inlet can increase the air velocity at the air outlet, thereby pushing the waste paper with a larger mass and further improving the self-cleaning efficiency of the protective cover 100.

[0029] Reference Figure 1 and Figure 2 As shown, the splicer protection device also includes a controller and a sensor 200. The sensor 200 is mounted on the protective cover 100 and located on one side of the guide ramp 110. The sensor 200 is used to detect whether there are foreign objects on the guide ramp 110. The sensor 200 and the air source are respectively communicatively connected to the controller. Optionally, the control mechanism can be a centralized or distributed controller. For example, the controller can be a single microcontroller or composed of multiple distributed microcontrollers. The microcontroller can run a control program to control the sensor 200 and the air source to achieve their functions.

[0030] By setting up a controller and a sensor 200, when the sensor 200 detects foreign objects such as waste paper on the guide slope 110, the sensor 200 sends a cleaning signal to the controller. The controller receives the cleaning signal and controls the air source to supply compressed gas to the cleaning air duct 130, thereby realizing real-time detection and processing of waste paper residue on the guide slope 110 and improving the controllability and intelligence of the protective cover 100.

[0031] Furthermore, the sensor 200 is configured as a photoelectric sensor, and the side wall of the protective cover 100 is provided with a mounting part 150 for fixing the photoelectric sensor phototube. A reflector is provided on one side of the guide slope 110, and the reflector extends along the normal of the guide slope 110. The photoelectric sensor and the reflector are positioned correspondingly.

[0032] By configuring the sensor 200 as a photoelectric sensor and using a reflector that can reflect detection light, the structure of the sensor 200 is simplified while ensuring the detection range and accuracy, making it easier to arrange and install the sensor 200.

[0033] Continue to refer to Figure 1 and Figure 2 As shown, it can be understood that the bolt assembly hole 120 includes a slotted hole 121 and a blind hole 122. The slotted hole 121 is arranged along the width direction of the protective cover 100, that is, the long axis of the slotted hole 121 is parallel to the width direction of the protective cover 100, and the slotted hole 121 penetrates the rear side wall of the protective cover 100 along the length direction of the protective cover 100. The blind hole 122 penetrates the guide slope 110 along the length direction of the protective cover 100 and communicates with the slotted hole 121. The diameter of the blind hole 122 is greater than the length of the slotted hole 121 in the vertical direction.

[0034] The bolt assembly hole 120 is set as an oblong hole 121 on the rear side wall of the protective cover 100, which makes it convenient for users to adjust the installation position of the protective cover 100 horizontally, adapt to splicers with different structural layouts, expand the application range of the protective cover 100, and improve the practicality of the protective cover 100.

[0035] Reference Figure 1 As shown, it is understandable that a connector 140 is provided at the air inlet.

[0036] By setting the connector 140, users can easily install, disassemble, or replace pipelines, improving the ease of installation and removal of the protective cover 100.

[0037] Furthermore, the protective cover 100 and the connector 140 are integrally molded parts. Specifically, the protective cover 100 and the connector 140 are integrally molded injection molded parts or 3D printed parts.

[0038] The protective cover 100 and the connector 140 are integrally molded, which can effectively improve the integrity of the protective cover 100 and the sealing performance of the connector 140. At the same time, the connector 140 has a simple structure, which makes it easier for users to control production costs.

[0039] According to an embodiment of this application, a paper splicer includes a feeding assembly, an accelerator, and the aforementioned splicer protection device. The feeding assembly, accelerator, and splicer are all mounted on a base plate on the side wall of a cigarette machine. The feeding assembly is located above the accelerator. The feeding assembly is the conveying roller in the paper splicer used to convey new paper rolls. The feeding assembly and the accelerator cooperate to convey the paper rolls to be spliced. The protective cover 100 is fixed above the accelerator and abuts against the top surface of the accelerator. The guide slope 110 is located between the feeding assembly and the accelerator.

[0040] Understandably, by guiding the waste paper rolls down through the protective cover 100, and by having the protective cover 100 abut against the top surface of the accelerator, fine paper scraps can be prevented from falling onto the splicer surface, thus optimizing scrap management, reducing splicer friction wear, and extending the service life of the paper roll splicer.

[0041] Reference Figure 3 As shown, it can be understood that a guide roller is provided between the feeding assembly and the accelerator. The guide roller is located on one side of the protective cover 100. The paper roll is tightly pressed against the surface of the guide roller. A baffle 160 is provided on the side of the guide slope 110 near the guide roller. The baffle 160 extends upward along the normal direction of the guide slope 110.

[0042] By setting up baffle 160, waste paper can be prevented from being rolled into the acceleration roller from the side wall of the accelerator, which effectively improves the structural rationality of the protective cover 100 and enhances the protective performance of the protective cover 100.

[0043] Furthermore, the side of the baffle 160 away from the guide slope 110 is provided with a relief part 161, which is a groove structure provided on the side wall of the baffle 160. The relief part 161 is used to avoid the guide roller.

[0044] By setting the avoidance part 161, the avoidance part 161 can avoid the guide roller, reduce the distance between the protective cover 100 and the guide roller, improve the space utilization of the protective cover 100, and thus improve the overall structural compactness of the paper splicer.

[0045] 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.
