Description

Technical Field

[0001] The invention relates to the field of motorcycle protective cover manufacturing, and in particular to automated motorcycle protective cover production equipment. Background Art

[0002] A motorcycle protective cover is a protective accessory designed specifically for motorcycles, bicycles, electric vehicles and other vehicles. Its main function is to prevent rain and dust from falling on the vehicle, to protect the parked vehicle, to avoid wetting and contamination, and to affect subsequent riding. This protective cover is usually made of highly elastic material, with one end open and gathered by a rubber band, so that it can be easily and tightly put on the outside of the motorcycle to prevent external pollutants from entering.

[0003] At the same time, the installation and replacement of this type of motorcycle protective cover is relatively simple, and users can choose a protective cover of appropriate size according to their needs. On the basis of mass production of motorcycle protective covers, corresponding processing equipment is also required. The existing protective cover processing equipment cannot easily process such motorcycle protective covers of different lengths, and due to the characteristics of motorcycle protective covers, the length of some motorcycle protective covers will far exceed the width. If this type of equipment is used directly, it is impossible to conveniently adjust the processing length of different bag bodies, and too long equipment is required to seal and cut the bag body, resulting in the equipment occupying too much area. At the same time, the protective covers processed by the existing protective cover processing equipment still have the problem that the rubber band shrinks after breaking, resulting in the entire protective cover being unable to continue to be used. There is an urgent need for an automated motorcycle protective cover production equipment that can mass produce and conveniently adjust the bag length to prepare protective covers of different specifications. At the same time, the automated motorcycle protective cover production equipment does not need to occupy too large a plant area, and the dustproof bags manufactured by it can improve product quality and extend service life. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automated motorcycle protective cover production device in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automated motorcycle protective cover production equipment, comprising a material unwinding device for conveying upper and lower layers of materials arranged in sequence along an effective transport direction, a rubber band pressing device for heat-sealing a rubber band to the edge of the material, a transverse sealing device for heat-sealing the edges of the corresponding sides of the mutually stacked materials, a longitudinal edge sealing device for heat-sealing the middle intervals of the transversely sealed materials into independent openings, a secondary heat sealing device for secondary heat sealing the longitudinally sealed materials, and a slitting device for slitting the secondary heat-sealed materials into independent protective covers, comprising: A material unwinding device arranged in the direction of heat sealing for conveying the upper and lower layers of materials, a rubber band pressing device for heat sealing the rubber band to the edge of the material, a transverse sealing device for heat sealing the edges of the corresponding sides of the stacked materials, a longitudinal edge sealing device for heat sealing the middle intervals of the sealed materials into independent openings, and a slitting device for slitting the materials into independent protective covers, both sides of the secondary heat sealing device are provided with sealing line fine-tuning mechanisms, and the sealing line fine-tuning mechanisms include a lifting frame, a lifting seat slidably arranged on the lifting frame, a lifting roller rotatably arranged on the lifting seat, and a roller height adjustment mechanism for adjusting the axial height of the lifting roller.

[0006] By adopting the above technical scheme, the upper and lower layers of materials are conveyed by the material unwinding device, the rubber band edge pressing device fixes the rubber band to the material, the transverse sealing device heat-seals the edges of the corresponding sides of the mutually stacked materials, the longitudinal edge sealing device heat-seals the middle intervals of the materials after transverse sealing into independent opening continuous roll-type protective covers, the secondary heat sealing device performs secondary heat sealing on the heat sealing line of the materials after longitudinal edge sealing to prevent the rubber band from loosening, and finally the slitting device slits the materials into independent protective covers, so that the motorcycle protective cover manufacturing equipment can realize batch production, and by setting the sealing line fine-tuning mechanism, it can be used in the secondary heat sealing device and the longitudinal edge sealing device. And the material is stored between the slitting device and the secondary heat sealing device, so that the sleeve body is set on the elevated roller for material storage, so as to avoid expanding the floor space, and the position of the heat sealing line can be accurately controlled by the roller height adjustment mechanism to ensure the accurate docking of the heat sealing line mouth and uniform heat sealing and precise slitting. At the same time, when preparing protective sleeves of different specifications, the user can directly replace materials of different widths to manufacture protective sleeves of different widths, and through the longitudinal edge sealing devices at different length positions, it can conveniently process protective sleeves of different lengths, and at the same time, the formed continuous rolls of protective sleeves are cut by the slitting device, so as to conveniently and efficiently prepare protective sleeves of different specifications.

[0007] The above-mentioned automated motorcycle protective cover production equipment can be further configured as follows: the roller shaft height adjustment mechanism includes screws arranged at both ends of the lifting seat and an adjusting rod passed through the lifting frame, the two ends of the lifting seat are threadedly connected with the screw, and the adjusting rod is provided with an adjusting handwheel after passing through the lifting frame. The adjusting rod and the screw are transmitted by a bevel gear, and the axial height of the lifting roller on the lifting frame is adjusted by rotating the adjusting handwheel.

[0008] By adopting the above technical scheme, the axial height of the lifting roller on the lifting frame can be accurately adjusted through the threaded connection of the screw and the adjusting rod. The setting of the adjusting handwheel allows the operator to adjust the height of the lifting roller through a simple rotation action. The operation is intuitive and convenient, which improves work efficiency. The setting of the screw and the adjusting rod makes the height adjustment mechanism occupy a smaller space and have a compact structure, saving equipment space and making the overall mechanical design more compact. There is a linear relationship between the rotation angle of the screw and the moving position of the sleeve. The control of the rotation angle of the screw can achieve the control of the moving distance of the target structure; and because of the use of threaded matching, the position adjustment of the screw and the sleeve does not affect the connection state of the threaded connection, which can reduce the deviation of the relative position during operation, thereby ensuring the accuracy of the adjustment precision.

[0009] The above-mentioned automated motorcycle protective cover production equipment can be further configured as follows: the secondary heat sealing device includes a heat sealing frame and a welding assembly arranged on the heat sealing frame, the welding assembly includes a welding frame, a welding seat arranged on the welding frame, a welding cylinder arranged on the welding seat, and a welding head arranged at the output end of the welding cylinder, the welding cylinder is used to drive the welding head to rise and fall axially, the welding frame is provided with sliders that can slide laterally along the heat sealing frame at both ends corresponding to the heat sealing frame, the welding frame is provided with a guide shaft, the welding seat sleeve is arranged outside the guide shaft, and can slide longitudinally along the guide shaft.

The welding frame can slide laterally along the heat sealing frame through the slider, which is convenient for adjusting the lateral position of the welding seat and the position of the welding head according to the different lengths of the sleeve so that it can be directly facing the heat sealing line position for secondary heat sealing. At the same time, it can slide longitudinally through the guide shaft to adapt to protective covers of different widths, thereby improving the adaptability of the equipment.

[0014] By adopting the above technical solution, the longitudinal sealing drive shaft and the cutter drive shaft are driven simultaneously by the main drive motor, which ensures the synchronization of the longitudinal edge sealing and slitting actions, improves the production efficiency and processing accuracy, and the design of the synchronous sprocket, the main drive sprocket and the longitudinal sealing sprocket enables the two devices to work at the same speed, thereby maintaining consistency during sealing and slitting. The sprocket chain and synchronous belt synchronous wheel as well as the pulley belt in this equipment can be easily interchanged.

[0015] The above-mentioned automated motorcycle protective cover production equipment can be further configured as follows: the first cam transmission mechanism includes a first eccentric bearing installed on both ends of the longitudinal seal transmission shaft corresponding to the upper longitudinal seal drive shaft, the inner ring of the first eccentric bearing is eccentrically installed on the outer peripheral surface of the longitudinal seal transmission shaft, and the outer ring is provided with an upper longitudinal seal hinge seat, one end of the upper longitudinal seal drive shaft is connected to the upper longitudinal seal plate, and the other end is hinged to the upper longitudinal seal hinge seat, the second cam transmission mechanism includes a second eccentric bearing installed on both ends of the longitudinal seal transmission shaft corresponding to the lower longitudinal seal drive shaft, the inner ring of the second eccentric bearing is eccentrically installed on the outer peripheral surface of the longitudinal seal transmission shaft, and the outer ring is provided with a lower longitudinal seal connecting seat, One end of the lower longitudinal seal drive shaft is connected to the lower longitudinal seal plate, and the other end is connected to the lower longitudinal seal connecting seat. As the longitudinal seal transmission shaft rotates, the upper longitudinal seal plate and the lower longitudinal seal plate are driven to move closer or separate relative to each other through the first and second eccentric bearings, thereby longitudinally sealing the passing material. The third cam transmission mechanism includes a third eccentric bearing installed on the two ends of the cutter drive shaft corresponding to the cutter drive shaft. The inner ring of the third eccentric bearing is eccentrically installed on the outer peripheral surface of the cutter drive shaft, and the outer ring is provided with a cutter connecting seat. One end of the cutter drive shaft is connected to the upper knife plate, and the other end is connected to the cutter connecting seat. As the cutter drive shaft rotates, it drives the cutter to cut the passing material.

[0016] By adopting the above technical scheme, the precise relative movement of the upper longitudinal sealing plate and the lower longitudinal sealing plate is achieved through the eccentric bearings in the first and second cam transmission mechanisms, thereby accurately controlling the longitudinal edge sealing process of the material. The inner ring of the eccentric bearing is eccentrically installed on the outer peripheral surface of the longitudinal sealing transmission shaft, and the outer ring is provided with a hinged seat, so that the longitudinal sealing plate can achieve accurate approaching or separation according to the rotation of the eccentric bearing. The third cam transmission mechanism also uses an eccentric bearing to control the synchronous movement of the cutter drive shaft and the upper knife plate to achieve precise cutting of the material. The design of the cutter loading and driving mechanism ensures the accuracy and consistency of the cutting process. The design of the cam transmission mechanism makes the equipment structure more compact, reduces space occupancy, and improves the transmission efficiency of the equipment.

[0017] The above-mentioned automated motorcycle protective cover production equipment can be further configured as follows: the rubber band edge pressing device includes an edge pressing frame, upper and lower rubber band edge pressing assemblies axially arranged on the edge pressing frame for fixing rubber bands to the edges of the upper and lower layers of materials respectively, and an edge pressing drive mechanism that drives the upper and lower rubber band edge pressing assemblies to work, the upper and lower rubber band edge pressing assemblies each include an ultrasonic embossing wheel group for sealing the rubber band into the material folding, a heating wheel group for heating and curing the folded edge of the embossed material, and a folding plate that folds the edge of the material in the material unwinding device and then feeds it into the ultrasonic embossing wheel group, the embossing wheel and the edge pressing heating wheel on the ultrasonic embossing wheel group and the heating wheel group are both arranged on the same side of the edge pressing frame.

[0018] By adopting the above technical scheme, the upper and lower rubber band edge pressing devices use the high-frequency vibration principle of ultrasound to transfer the sound wave energy to the contact surface between the rubber band and the material folding edge, so that the rubber band and the material edge are combined under high-frequency vibration to form a tight edge sealing, which can form a uniform pattern on the edge of the material. The edge after treatment is smooth and wrinkle-free, which improves the aesthetics of the finished product. After ultrasonic embossing, the heating wheel group heats and cures the material folding edge, so that the embossed material edge can be quickly bonded and shaped, and the firmness of the edge sealing is enhanced. Such treatment makes the rubber band tightly combined with the material, enhances the fixation, and prevents the rubber band from shrinking. Due to the firm fixation of the rubber band and the flat treatment of the material edge, even if the protective cover is broken at the elastic edge or on the car body, the rubber band will not shrink, and will not hinder the continued use of the protective cover, thereby ensuring the service life of the protective cover. Through the drive of the edge pressing drive mechanism, it is ensured that the upper and lower rubber band edge pressing components can work synchronously, so that the rubber band fixation of the upper and lower layers of materials is carried out simultaneously, which improves production efficiency and processing quality.

[0020] By adopting the above technical scheme, the transverse sealing device includes a transverse sealing frame and a transverse sealing heating wheel group. The heating wheel group is used to heat-seal the edges of the upper and lower groups of materials into a dust-proof bag to ensure the firmness of the connection. At the same time, since the transverse sealing device and the rubber band edge pressing device share a edge pressing drive mechanism as a power source, the synchronization of the two devices can be ensured, thereby improving the coordination and efficiency of the entire manufacturing process, reducing the time and management costs required for separate control, thereby improving the work efficiency and production capacity of the production line. At the same time, a unified driving force can ensure that the force applied in different operation steps is consistent, which helps to maintain the quality consistency of the finished product, improve the product qualification rate, reduce the need for multiple independent drive systems, simplify the design and maintenance of the equipment, and reduce costs and failure rates. The edge pressing drive mechanism includes an edge pressing electric The machine and a series of transmission rollers realize synchronous operation between different components through the cooperation of the main drive belt, the lower edge pressing belt and the upper edge pressing belt. Through the precise mechanical transmission system, precise control of the upper and lower rubber band edge pressing components is realized, which improves the working efficiency and processing accuracy of the manufacturing machine, reduces the time and management cost required for separate control, and improves the synchronization, so that the upper and lower layers of materials after edge pressing can be directly and synchronously sealed together through the transverse sealing heating wheel group, and the first transmission roller drives the lower rubber band edge pressing assembly through the lower edge pressing belt, and the second transmission roller drives the upper rubber band edge pressing assembly through the upper edge pressing belt.

Such a design further optimizes the production process and reduces manufacturing costs.

[0021] The above-mentioned automated motorcycle protective cover production equipment can be further configured as follows: a traction roller group for delivering materials along an effective transportation direction is provided between the transverse sealing device and the longitudinal edge sealing device, the traction roller group and the transverse sealing device rotate synchronously through a synchronous belt, the ultrasonic embossing wheel group and the heating wheel group rotate synchronously through an embossing belt, a storage mechanism is provided between the traction roller group and the longitudinal edge sealing device, the storage mechanism includes a storage rack arranged above the edge banding frame and a rocker plate below, one end of the rocker plate is hinged to the edge banding frame, rocker cylinders are provided on both sides of the edge banding frame corresponding to the rocker plate, one end of the rocker cylinder is hinged to the edge banding frame, and the output end is hinged to both sides of the rocker plate, and the rocker plate and the storage rack are provided with a plurality of storage rollers for materials to be staggered up and down.

[0022] By adopting the above technical scheme, the traction roller group rotates synchronously with the transverse sealing device and the longitudinal edge sealing device through the synchronous belt, ensuring the continuity of the material and the consistency of processing, ensuring the stable delivery of the material in the effective transportation direction, and improving the production efficiency and yield rate. At the same time, by controlling the conveying amount of the traction roller group, the length of the sleeve can be conveniently adjusted. The storage mechanism includes a storage rack and a rocker plate. The swing of the rocker plate is controlled by the rocker cylinder to realize temporary storage and orderly arrangement of the material, prevent the accumulation and wrinkling of the material during the longitudinal sealing and slitting process, and ensure the flatness and processing quality of the material.

[0024] By adopting the above technical solution, the use of the unwinding lifting cylinder enables the unwinding frame to rotate along the hinge axis, driving the unwinding roller to rise or fall. In this way, the height of the unwinding roller can be adjusted according to the thickness and characteristics of different materials, thereby increasing the flexibility and adaptability of the equipment, so that the upper and lower material unwinding components can respectively deliver the upper and lower materials to the rubber band pressing device evenly and stably.

[0056] 2. Rubber band edge pressing: The upper rubber band edge pressing assembly 22 and the lower rubber band edge pressing assembly 23 process the edges of the upper and lower layers of materials respectively. First, the edge folding part is covered with the rubber band by the folding plate 223, and then the rubber band is sealed into the material folding edge by the ultrasonic embossing wheel group 221. The embossed material folding edge is heated and cured by the heating wheel group 222, and then the upper and lower layers of the edge pressed materials are closed and pulled into the rear transverse sealing device 3 through the pulling roller group 4.

[0057] 3.

[0061] 7. Cutting: The cutting device 8 cuts the material after the secondary heat sealing into independent dust covers to complete the production of the final product.

[0062] 8. Conveying finished products: The cut dust cover is conveyed out through the conveyor belt 80, completing the entire production process.
