Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a rubber roller cooling structure for an ultra-high-speed filter tip assembling machine. Background Art

[0002] With the development of the tobacco industry, ultra-high-speed equipment is widely used to improve production efficiency. At the same time, higher quality requirements are also put forward for cigarettes. Wrapping the filter with a layer of tipping paper is an indispensable process for producing finished cigarettes, so there are higher requirements for gluing the tipping paper, that is, the glue applicator. The main component of the glue applicator is the glue roller, which is a pair composed of a glue coating roller and a glue control roller. The latex is pressed out by a glue pump and flows between the two rollers of the glue cylinder. The two rollers are tightly attached to each other with a certain pressure and rotate relative to each other. There are shallow sol grooves on the glue control roller, and the depth is related to the amount of glue. In this way, a thin layer of glue is printed on the glue coating roller, and the excess glue is sent back to the glue cylinder for recycling. In the production process, the two rubber rollers are in close contact and rotate at high speed, which will generate a lot of heat, causing the surface temperature of the rubber roller to gradually increase. High temperature will cause the glue to agglomerate and form a solid glue layer on the surface, affecting the thickness and uniformity of the glue coating, causing quality defects of cigarettes. Therefore, the rubber roller usually needs to be cleaned after a shift. One is to clean the glue liquid on it, and the other is to slightly reduce the temperature of the rubber roller.

[0003] Although regular cleaning can cool down the rubber roller, the problem of different glue coating caused by temperature differences cannot be avoided. Disassembly and assembly is a troublesome process, and stains are more likely to enter the inside of the rubber roller during the cleaning process, which is not conducive to maintenance.

[0008] Preferably, a through hole connected to a high-speed rotary joint is provided at the axis of the half shaft, the mandrel and the mandrel. The high-speed rotary joint is connected to a high-pressure gas source, and the high-pressure gas is input into the roller axis hole through the through hole.

[0009] Preferably, the diameter of the roller axial hole is small in the middle and large at both ends, the ejector pin slides in the small diameter hole in the middle but is airtight, a certain gap is arranged between the ejector pin and the large diameter holes at both ends for air to circulate, the two roller radial holes are respectively connected with the large diameter holes at both ends, and the two roller radial holes are respectively connected with the two ends of the spiral groove.

[0010] Preferably, the slider is made of rubber with a certain elasticity, and the slider is transitionally matched with the coupling so that the slider can be inserted into the coupling and can transmit torque. When the slider is pulled out of the coupling, the rubber roller assembly and the half shaft form two independent entities.

[0011] Preferably, the outer end of the roller shaft near the piston is connected to a handle through a thread, and a pressure cover is fixedly installed on the outer end surface of the handle through a countersunk screw, and a gasket is arranged between the pressure cover and the handle so that a distance is set between the pressure cover and the handle to facilitate air circulation.

[0012] Preferably, when the slider is inserted into the coupling, the ejector head pushes the ejector rod to slide toward the end of the rubber roller assembly, and at the same time, the ejector rod pushes the ejector pin to slide inside the rubber roller assembly through the steel ball. At this time, the piston moves outward so that the O-ring no longer seals the end of the roller axial hole, so that high-pressure air can be input from one end of the roller axial hole and flow through the spiral groove and out from the other end.

[0013] Preferably, when the slider is pulled out of the coupling, the push head no longer applies push rod thrust, and the sealing spring pushes the steel ball and the push rod to slide outward to seal the center hole of the coupling.

[0014] The utility model provides a cooling structure for a rubber roller of an ultra-high-speed filter tip assembling machine, which has the following beneficial effects:

[0015] 1. The rubber roller cooling structure for the ultra-high-speed filter tip assembler has the effect of making the rubber roller run at a constant temperature and high speed to achieve uniform glue coating through the matching arrangement of the rubber roller assembly and the high-speed rotary joint. Since the rubber roller assembly is provided with spiral grooves with a large area and roller axial holes for air inlet and outlet, high-pressure cold air can be injected into the high-speed rotating rubber roller assembly through the high-speed rotary joint. The cold air flowing through the spiral groove can take away the heat generated by the rubber roller to achieve the purpose of cooling the high-speed rotating rubber roller.

[0016] 2. The rubber roller cooling structure for the ultra-high-speed filter tip assembler has the effect of facilitating the disassembly and assembly of the rubber roller through the coordinated arrangement of the coupling and the slider. The slider is fixed to the end of the half shaft, and the coupling is fixed to the end of the rubber roller assembly. Since the coupling and the slider are connected by plugging and pulling, and the linkage of the two can transmit torque, the rubber roller assembly and the coupling can be disassembled into two independent individuals or transmit torque in parallel by plugging and pulling with a little force, thereby making the disassembly and assembly of the rubber roller assembly very convenient.

[0017] 3. The rubber roller cooling structure for the ultra-high-speed filter tip assembler has the effect of preventing dirt from entering the inside of the rubber roller through the coordinated arrangement of the piston, the return spring, the steel ball and the blocking spring. When the rubber roller assembly is disengaged from the half-shaft, the blocking spring pushes the steel ball to block the center hole of the coupling, and at the same time the return spring pushes the piston to slide inward and outward to block the end of the roller axis hole, so that both ends of the rubber roller assembly are blocked to prevent debris from entering the roller axis hole during cleaning.

[0023] See also Figures 1 to 3The utility model provides a technical solution: a rubber roller cooling structure for an ultra-high-speed filter tip assembling machine, comprising a rubber roller assembly 1 and a half shaft 2, the rubber roller assembly 1 comprising a roller shaft 101 and an outer roller 102, a roller axis hole 103 is provided at the axis center of the roller shaft 101, roller warp holes 104 are provided at both ends of the roller axis hole 103, a spiral groove 105 is provided in the inner hole of the outer roller 102, a clearance-matched ejector pin 3 is inserted into the roller axis hole 103, the diameter of the roller axis hole 103 is small in the middle and large at both ends, the ejector pin 3 slides in the small diameter hole in the middle but is not airtight, a certain gap is set between the ejector pin 3 and the large diameter holes at both ends for air to circulate, the two roller warp holes 104 are respectively connected to the large diameter holes at both ends, and the two roller warp holes 104 are respectively connected to the large diameter holes at both ends, and the two roller warp holes 104 are respectively connected to the large diameter holes at both ends. The two ends of the spiral groove 105 are connected, one end of the ejector pin 3 is connected to the piston 4 through a thread, the outer end of the roller shaft 101 near the piston 4 is connected to the handle 14 through a thread, the outer end surface of the handle 14 is fixed with a gland 15 through a countersunk screw, a gasket 16 is arranged between the gland 15 and the handle 14, so that the gland 15 and the handle 14 are arranged with a distance to facilitate air circulation, the outer side surface of the inner end of the piston 4 is clamped with an O-ring 5 through a slot, the outer end of the piston 4 is provided with a return spring 6, the other end of the ejector pin 3 is provided with a steel ball 7, the outer surface of the ejector pin 3 near the steel ball 7 is sleeved with a blocking spring 8, the end of the roller shaft 101 near the steel ball 7 is installed with a coupling 9, and a ejector pin 10 with a clearance fit is installed at the axis of the coupling 9 and the roller shaft 101, and the semi-circular roller 101 is provided with a plurality of couplings. One end of the shaft 2 close to the rubber roller assembly 1 is connected with a plug 11 through a thread, and a slider 12 is fixedly installed between the plug 11 and the plug 11. The material of the slider 12 is rubber with a certain elasticity. The slider 12 and the coupling 9 are transitionally matched, so that the slider 12 can be inserted into the coupling 9 and can transmit torque. When the slider 12 is pulled out of the coupling 9, the rubber roller assembly 1 and the half-shaft 2 form two independent individuals. A high-speed rotary joint 13 is installed at the other end of the half-shaft 2. The axis of the half-shaft 2, the plug 11 and the ejector rod 10 are all provided with a through hole connected to the high-speed rotary joint 13. The high-speed rotary joint 13 is connected to a high-pressure gas source, and the high-pressure gas is input into the roller axis hole 103 through the through hole. When the slider 12 is inserted into the coupling 9, the plug 11 pushes the ejector rod. 10 slides toward the end of the rubber roller assembly 1, and at the same time, the push rod 10 pushes the push pin 3 to slide in the rubber roller assembly 1 through the steel ball 7. At this time, the piston 4 moves outward so that the O-ring 5 no longer seals the end of the roller axis hole 103, so that high-pressure air can be input from one end of the roller axis hole 103 and flow through the spiral groove 105 and then flow out from the other end. When the slider 12 is pulled out of the coupling 9, the head 11 no longer applies thrust to the push rod 10. At this time, the blocking spring 8 pushes the steel ball 7 and the push rod 10 to slide outward to block the center hole of the coupling 9. At the same time, the reset spring 6 pushes the piston 4 to slide inside and outside through the O-ring 5 to block the end of the roller axis hole 103, so that both ends of the rubber roller assembly 1 are blocked to prevent debris from entering the roller axis hole 103 during cleaning.

[0024] When in use, the half shaft 2 is processed into a hollow core, and a high-speed rotary joint 13 is installed at the tail end to connect the high-pressure air cooled by the vortex tube. The high-speed rotary joint 13 is required to rotate flexibly and will not affect the air circulation when the rubber roller rotates at high speed. The other end is connected to the slider 12 with the top head 11 to form an integral body and rotate with it, and the rubber roller is driven to rotate through the coupling 9 fixed to the rubber roller. Because the spherical surface is easier to adjust the balance, the top rod 10 is processed into an outer spherical surface at one end to match the inner hemispherical surface of the top head 11, and the other end is processed into an inner spherical surface to match the surface of the steel ball 7, and 4 2-3mm grooves are opened to allow the atmosphere to pass through. The top rod 10 is installed at the end of the rubber roller shaft. The rubber roller is in a free state and is limited by the coupling 9. When the rubber roller is disassembled for cleaning, the coupling 9 is disengaged from the slider 12, and the push rod 10 and the top head 11 are separated to form two independent parts. In order to prevent water from entering the rubber roller during cleaning, both ends are equipped with sealing rings for sealing, that is, when the slider 12 is pulled out of the coupling 9, the top head 11 no longer applies the thrust of the push rod 10. At this time, the blocking spring 8 pushes the steel ball 7 and the push rod 10 to slide outward to block the center hole of the coupling 9. At the same time, the reset spring 6 pushes the piston 4 to slide inside and outside to block the end of the roller axis hole 103 through the O-ring 5. The rubber roller is made into a split type, which is composed of a roller and a roller shaft. The inner cavity of the roller is processed The spiral groove 105 is connected with the roller axis hole 103 on the roller shaft to form an air spiral channel. The air spirals through the inside of the channel to take away the heat of the rubber roller, thereby cooling the rubber roller. The ejector pin is a slender shaft with a diameter of 3-5 mm. One end is fixed to the piston 4, and the other end pushes the ejector pin 10 through the steel ball 7. The steel ball 7 and the ejector pin 10 are also in spherical contact. The ejector pin is installed inside the rubber roller shaft. Springs are installed at both ends. The sealing degree of the piston 4 can be changed by the tensioning elastic force of the spring. When installing, the ejector pin is required to move flexibly in the rubber roller shaft without any clearance. Finally, the hot air is dispersed and transferred to the rubber roller through the circumferential gap between the handle 14 and the pressure cover 15. The outside world is used to achieve the effect of cooling the rubber roller. Since the rubber roller is always supplied with high-pressure cold air when it is working, the cold air continuously enters the inside of the rubber roller and spirally flows to take away the heat, so that the temperature of the rubber roller can be effectively reduced and cooled down. When the machine is in a non-working state, the rubber roller can be pulled out, that is, the coupling 9 and the slider 12 are separated to form two independent bodies. When the machine is working, the springs installed in the cores at both ends of the rubber roller shaft are in a compressed state. When the rubber roller is pulled out, the spring reset push rod 10 drives the piston 4 and pushes the steel ball 7 to push the push rod 10 out, completing the sealing of the two ends of the rubber roller shaft. In this way, the rubber roller can be cleaned to prevent water and debris from entering the rubber roller.

[0025] In summary, the rubber roller cooling structure for the ultra-high-speed filter tip assembling machine has a large-area spiral groove 105 and a roller axis hole 103 for air inlet and outlet, and the high-speed rotating joint 13 can be used to inject high-pressure cold air into the high-speed rotating rubber roller assembly 1. The cold air flowing through the spiral groove 105 can take away the heat generated by the rubber roller to achieve the purpose of cooling the high-speed rotating rubber roller. The slider 12 is fixed to the end of the half shaft 2, and the coupling 9 is fixed to the end of the rubber roller assembly 1. Since the coupling 9 and the slider 12 The connection is made by plugging and unplugging, and the linkage of the two can transmit torque, so the rubber roller assembly 1 and the coupling 9 can be disassembled into two independent individuals or transmitted in parallel with a little plugging and unplugging, which makes the disassembly and assembly of the rubber roller assembly 1 very convenient. When the rubber roller assembly 1 is disengaged from the half shaft 2, the blocking spring 8 pushes the steel ball 7 to block the center hole of the coupling 9, and the reset spring 6 pushes the piston 4 to slide inward and outward to block the end of the roller axis hole 103, so that both ends of the rubber roller assembly 1 are blocked to prevent debris from entering the roller axis hole 103 during cleaning.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
