Description

Technical Field

[0001] This utility model relates to the field of tobacco machine external guide strip technology, and more specifically, it relates to an external guide strip at the front end of a suction ribbon. Background Technology

[0002] In modern light industries such as tobacco and chemical fibers, negative pressure adsorption conveying devices are core equipment for the efficient and continuous transport of materials such as fibers and tows. The suction belt, as a key actuator, is a ring-shaped, typically microporous, flexible belt that, under negative pressure, tightly adheres to the vacuum inlet, generating a strong adsorption force to grasp and transport materials. The operational stability of the suction belt, especially its dynamic behavior as it enters the inlet area, directly determines the efficiency, reliability, and product quality of the entire conveying system.

[0003] In practical applications, the working conditions of the front end of the suction belt (i.e., the suspended section that detaches from the roller or guide rail and begins to enter the vacuum suction port) are the most severe. Because it is in the transition zone from a free state to a constrained state, this section of the belt may experience curling, lateral deviation, and vibration during high-speed operation. Utility Model Content

[0004] The purpose of this invention is to provide an external guide strip at the front end of a suction ribbon to solve the problems in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an outer guide strip at the front end of a suction ribbon, comprising: a base plate and a guide block; the guide block is fixedly disposed on the base plate, the top surface of the guide block is fixedly connected to the base plate, the bottom surface of the guide block is provided with a guide groove with open ends, a pressure plate is provided on the bottom surface of the guide block, and an anti-cavity groove is provided on the axial direction of the guide block.

[0006] By effectively preventing and correcting edge curling of the suction ribbon; providing reliable lateral restraint to suppress deviation and vibration; minimizing friction and wear between the suction ribbon and the suction ribbon while achieving constraint; and reducing component weight and facilitating installation and maintenance through the clearance groove, a comprehensive effect of stable guidance, efficient edge curling prevention, and ultra-low wear is achieved in synergy.

[0007] The present invention is further configured such that the guide block is U-shaped as a whole.

[0008] By adopting a U-shaped cross-section, its two side walls can naturally hug the suction ribbon from both sides, providing reliable lateral restraint, effectively suppressing the left and right deviation and shaking of the suction ribbon during operation, and ensuring its smooth operation along a straight line.

[0009] The present invention is further configured such that: the bottom surface of the guide groove is provided with a plurality of evenly arranged mounting holes, and each mounting hole contains a corresponding ball.

[0010] By incorporating ball bearings, the back of the suction ribbon contacts the ball bearings as it passes through the guide groove, transforming the traditional surface-to-surface sliding friction into point-contact rolling friction. This significantly reduces the coefficient of friction and operating noise, thereby minimizing wear on the suction ribbon.

[0011] The present invention is further configured such that a pressure spring is provided between the mounting hole and the ball bearing.

[0012] By incorporating a pressure spring, a continuous, flexible upward support force is provided to the ball bearings. This ensures that the ball bearings remain in contact with the back of the suction ribbon, preventing momentary disengagement due to manufacturing tolerances or suction ribbon vibration, resulting in a more stable and reliable rolling friction reduction effect. Simultaneously, the spring's cushioning effect protects both the ball bearings and the suction ribbon from impact damage.

[0013] The present invention is further configured such that: the pressure plate includes a horizontal part and a vertical part, the horizontal part is connected to the bottom surface of the guide block, and the vertical part is in close contact with the outer side wall of the guide block.

[0014] By employing an L-shaped pressure plate design, the horizontal part is used to fix itself and assist in limiting the ball bearings, while the vertical part acts as a robust mechanical barrier, directly blocking any edge of the suction tape that attempts to curl upwards from the front, fundamentally preventing curling. This integrated design combines the pressing and anti-curling functions into one, resulting in a compact and efficient structure.

[0015] In summary, this utility model has the following beneficial effects: it effectively prevents and corrects the curling of the suction ribbon edge; it provides reliable lateral limiting to suppress deviation and shaking; it minimizes friction and wear between the suction ribbon and the suction ribbon while achieving constraint; and the clearance groove reduces the weight of the component and facilitates installation and maintenance, thereby achieving a comprehensive effect of stable guidance, efficient anti-curling, and ultra-low wear.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below, but the scope of protection of the present invention is not limited to the following description. Example

[0025] like Figure 1 and Figure 2 As shown, this embodiment provides an outer guide strip at the front end of a suction ribbon, including: a base plate 1 and a guide block 2; the guide block 2 is fixedly disposed on the base plate 1, the top surface of the guide block 2 is fixedly connected to the base plate 1, the bottom surface of the guide block 2 is provided with a guide groove 22 that is open at both ends, a pressure plate 24 is provided on the bottom surface of the guide block 2, and an anti-cavity groove 21 is provided in the axial direction of the guide block 2.

[0026] By effectively preventing and correcting the curling of the suction ribbon edge; providing reliable lateral limit to suppress deviation and vibration; and minimizing friction and wear between the suction ribbon and the suction ribbon while achieving constraint; the clearance groove 21 reduces the weight of the component and facilitates installation and maintenance, thus achieving a comprehensive effect of stable guidance, efficient anti-curling, and ultra-low wear.

[0027] The guide block 2 is U-shaped. By adopting a U-shaped cross section, its two side walls can naturally hug the suction ribbon from both sides, providing reliable lateral limit, effectively suppressing the left and right deviation and shaking of the suction ribbon during operation, and ensuring that it runs smoothly along a straight line.

[0028] In this embodiment, the clearance groove 21 opened in the guide block 2 is a through groove with open ends. The cross-section of the clearance groove 21 is a door-shaped structure. The clearance groove 21 can reduce shock and weight.

[0029] The bottom surface of the guide groove 22 has several evenly arranged mounting holes, and each mounting hole contains a corresponding ball 23. By setting the ball 23, when the suction ribbon passes through the guide groove 22, its back side contacts the ball 23, which transforms the traditional surface-to-surface sliding friction into point-contact rolling friction, thereby greatly reducing the coefficient of friction and operating noise, and reducing the wear of the suction ribbon.

[0030] A pressure spring 25 is provided between the mounting hole and the ball 23. By providing the pressure spring 25, a continuous and flexible upward support force can be provided to the ball 23. This ensures that the ball 23 always keeps in contact with the back of the suction ribbon, avoiding instantaneous disengagement caused by manufacturing tolerances or suction ribbon vibration, making the rolling friction reduction effect more stable and reliable. At the same time, the buffering effect of the spring also protects the ball 23 and the suction ribbon from impact damage.

[0031] The pressure plate 24 includes a horizontal part 241 and a vertical part 242. The horizontal part 241 is connected to the bottom surface of the guide block 2, and the vertical part 242 is close to the outer side wall of the guide block 2. By adopting an L-shaped pressure plate 24 design, its horizontal part 241 is used to fix itself and assist in limiting the ball 23, while the vertical part 242 acts as a sturdy mechanical barrier, directly blocking any edge of the suction ribbon that attempts to curl up from the front, thus fundamentally eliminating the occurrence of curling. This integrated design combines the pressing and anti-curling functions into one, making the structure compact and efficient.

[0032] In this embodiment, the horizontal portion 241 and the vertical portion 242 are integrally formed, such as Figure 1 As shown, a rounded chamfer is provided on the outer side where the horizontal part 241 intersects with the vertical part 242 to prevent tearing of the absorbent ribbon.

[0033] In this embodiment, in order to accommodate the function of the ball 23, a through hole is provided on the horizontal part 241 of the pressure plate 24 corresponding to the mounting hole. The through hole can expose at least one-third of the ball part of the ball 23 and at most no more than half of the ball part.

[0034] In this embodiment, the pressure plate 24 and the guide block 2 are fixedly connected by bolts.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
