Description

Technical Field

[0001] This application relates to the technical field of tobacco processing equipment, and relates to a glue storage device for a forming machine for applying glue. Background Art

[0002] Middle-line glue is one of the main raw and auxiliary materials for the production of cigarette filter rods, and is used for bonding the forming paper and the tow during the forming process of cigarette filter rods to prevent the filter tip from becoming unfastened.

[0003] An existing filter rod forming machine is equipped with a middle-line glue cylinder. During the operation of the forming machine, middle-line glue needs to be continuously consumed and sprayed on the cigarette filter rods. Therefore, it is necessary to regularly supplement middle-line glue into the middle-line glue cylinder on the forming machine. Since the viscosity of the middle-line glue is relatively high and it is easy to solidify, it cannot be transported over a long distance through pipelines, and can only be supplemented into the glue cylinder of the forming machine in barrels regularly.

[0004] Generally, the glue adding worker stores the middle-line glue in a storage tank, and then pulls the storage tank to a designated position to replenish glue for the forming machine. Generally, the storage tank only has a storage function. When replenishing glue for the forming machine, it is necessary to open the communication port, catch the middle-line glue coming out of the communication port with a small bucket, and finally add the middle-line glue in the small bucket into the middle-line glue cylinder of the forming machine. Since the position of the middle-line glue cylinder of the forming machine is relatively high from the ground (about 1.7 meters), it is not convenient to add glue to the forming machine.

[0046] This application makes improvements and innovations and proposes the following embodiments.

[0047] In some embodiments, please refer to Figures 1 to 9 , a glue storage device for a molding machine to add glue is provided, including:

[0048] A glue storage tank 1, an opening 11 is provided at the top of the glue storage tank 1, and a communication port 12 is provided at the bottom of the glue storage tank 1; a valve member 13 is provided on the communication port 12; the communication port 12 is communicated with a pipe body 17;

[0049] A cover body 2, the cover body 2 is covered on the opening 11, and the cover body 2 is detachably and sealingly connected to the edge of the opening 11; a pressure regulating structure 3 for changing the internal liquid pressure of the glue storage tank 1 is provided on the cover body 2; a through hole 21 for the driving end of the pressure regulating structure 3 to enter is provided on the cover body 2;

[0050] A support frame 4, the support frame 4 is fixedly connected to the bottom of the glue storage tank 1.

[0051] Among them, the valve member 13 is a three-way valve, and the communication port 12 is communicated with the liquid outlet pipe and the liquid inlet pipe through the three-way valve. The separation of the liquid outlet pipe and the liquid inlet pipe is realized by setting the three-way valve.

[0052] The glue storage tank 1 is arranged on a mobile vehicle for mobile glue replenishment of the molding machine. Arranging the mobile vehicle facilitates the movement of the glue storage tank 1.

[0053] A pressure regulating mechanism is arranged on the glue storage tank 1 to adjust the liquid pressure in the glue storage tank 1. When the pressure in the glue storage tank 1 is increased, the liquid in the glue storage tank 1 is discharged from the pipe body 17, and the pipe body 17 is connected to the middle glue cylinder of the stabbing molding machine, thereby realizing glue replenishment of the molding machine. When the liquid pressure in the glue storage tank 1 is reduced so that the pressure in the glue storage tank 1 is less than the external pressure, the liquid can flow into the glue storage tank 1 from the communication port 12 to realize glue addition to the glue storage tank 1.

[0054] The glue replenishment of the molding machine is achieved through the cooperation of the pressure regulating structure 3 and the pipe body 17, avoiding the situation where manual operation is required to load the center line glue into a barrel and then add it to the molding machine, making the glue adding work for the molding machine convenient and fast.

[0055] By setting the pressure regulating structure 3 to adjust the pressure in the glue storage tank 1, the discharging or replenishing of the glue in the glue storage tank 1 is realized, avoiding the situation where a pump body needs to be connected to the connection port 12 of the glue storage tank 1. Moreover, since the pumping direction of the pump body cannot be changed, a pump body is required to add the center line glue in the glue storage tank 1 to the molding machine, and another pump body is needed when adding glue to the glue storage tank 1. The pressure regulating structure 3 designed in this application can reduce the use of pump bodies and lower the production cost.

[0056] In one embodiment, a bag body 5 is provided in the glue storage tank 1; the bag body 5 has a closed space for storing glue; the bag body 5 is provided with a connection port communicating with the connection port 12; the connection port communicates with the closed space. Setting the bag body 5 can avoid the influence on the pressure regulating structure 3 due to the oxidation of the center line glue. Moreover, sealing the center line glue in the bag body 5 reduces the contact between the center line glue and air, reduces the oxidation of the center line glue, and extends the storage time of the center line glue.

[0057] In one embodiment, the pressure regulating structure 3 includes an air pipe 31; the air pipe 31 communicates with the through hole 21. By connecting the air pipe 31 to the through hole 21, the internal pressure of the glue storage tank 1 is adjusted. This adjustment structure is ingeniously designed, simple in structure, practical and reliable.

[0058] Specifically, the air pipe 31 is hermetically connected to the through hole 21, and a three-way valve is provided on the air pipe 31. The other two ends of the three-way valve are respectively communicated with a high-pressure air source and a negative-pressure source. The high-pressure air source is nitrogen or other inert gases. Introducing nitrogen can reduce the oxidation of the center line glue and extend the storage time of the center line glue.

[0059] The air pressure introduced into the air pipe 31 acts evenly on the bag body 5, avoiding the situation where the bag body 5 is locally stressed too much and improving the service life of the bag body 5.

[0060] In one embodiment, the pressure regulating structure 3 includes a telescopic cylinder 32 and a pressing plate 6 located above the bag body 5; the telescopic cylinder 32 is fixedly connected to the cover body 2, and the telescopic part of the telescopic cylinder 32 passes through the through hole 21 and is fixedly connected to the pressing plate 6; the pressing plate 6 can reciprocate vertically in the glue storage tank 1. By pushing the pressing plate 6 downward by the telescopic cylinder 32 to squeeze the bag body 5, the center line glue in the bag body 5 is pressed and flows out through the connection port 12 into the pipe body 17. The pipe body 17 is inserted into the center line glue cylinder of the molding machine, and finally the glue adding action for the molding machine is realized.

[0061] Specifically, the pressing plate 6 is hermetically attached to the inner wall of the glue storage tank 1. When the pressing plate 6 moves, the pressure of the center line glue below the pressing plate 6 will change. When the pressing plate 6 moves downward, the center line glue in the bag body 5 can be discharged. When the pressing plate 6 moves upward, the pressure below the pressing plate 6 is less than the atmospheric pressure. Therefore, the center line glue will be filled into the glue storage tank 1 through the pipe body 17, realizing the glue addition to the glue storage tank 1. The pressing plate 6 and the telescopic cylinder 32 have simple structures and reliable use.

[0062] Specifically, the telescopic cylinder 32 is a hydraulic cylinder.

[0063] In one embodiment, a sliding hole 61 is formed in the pressing plate 6; a first cylinder body 62 is slidably connected in the sliding hole 61, and a second cylinder body 63 is slidably arranged in the first cylinder body 62; a plate body 64 is slidably connected inside the second cylinder body 63; the telescopic part of the telescopic cylinder 32 is fixedly connected to the top of the plate body 64; the bottom of the plate body 64 is fixedly connected to the bag body 5. During the process of the telescopic cylinder 32 pushing the pressing plate 6 to move, the telescopic cylinder 32 pushes the plate body 64 to move through the first cylinder body 62 and the second cylinder body 63 in sequence, discharging the center line glue located in the first cylinder body 62 and the second cylinder body 63 from the first cylinder body 62 and the second cylinder body 63, improving the discharge rate of the center line glue in the bag body 5.

[0064] In one embodiment, an exhaust hole is formed in the plate body 64, the exhaust hole is communicated with the closed space inside the bag body 5, and an exhaust valve 65 is arranged on the exhaust hole. The arrangement of the exhaust valve 65 can facilitate the discharge of the gas inside the bag body 5 and improve the accommodation rate of the bag body 5.

[0065] In one embodiment, a plurality of telescopic rods 7 are arranged inside the glue storage tank 1. The plurality of telescopic rods 7 are circumferentially spaced apart along the bottom surface of the glue storage tank 1. One end of the telescopic rod 7 is fixedly connected to the bottom surface of the glue storage tank 1, and the other end is fixedly connected to the pressing plate 6; the telescopic rods 7 are located outside the bag body 5, and a fixing ring 71 is fixedly connected to the outer surface of the bag body 5; the fixing ring 71 is slidably sleeved on the telescopic rod 7. By arranging the telescopic rods 7 and connecting the outside of the bag body 5 to the telescopic rods 7 through the fixing ring 71, when the telescopic cylinder 32 moves upward, the top of the bag body 5 moves upward along with the plate body 64. Due to the restriction of the fixing ring 71 on the side of the bag body 5, the side of the bag body 5 can only move upward along the extending direction of the telescopic rod 7. Therefore, the volume of the bag body 5 increases, making the pressure inside the bag body 5 less than the atmospheric pressure. Therefore, the center line glue enters the inside of the bag body 5 through the pipe body 17. Although the structure setting is more complex than the case where the plate body 64 and the inner wall of the glue storage tank 1 are hermetically attached, the processing accuracy and material requirements for the hermetic attachment of the plate body 64 and the inner wall of the glue storage tank 1 are higher, and the processing cost and material cost are greater. By arranging the fixing ring 71 and the telescopic rods 7, the processing cost and material cost are smaller.

[0066] Specifically, a plurality of fixing rings 71 are sleeved on each telescopic rod 7, and the fixing rings 71 are spaced apart on the bag body 5.

[0067] In one embodiment, a plurality of sliding grooves 14 are formed on the inner wall of the glue storage tank 1, and the plurality of sliding grooves 14 are arranged at intervals along the circumferential direction of the inner wall of the glue storage tank 1; a plurality of sliding blocks 15 are slidably clamped in each sliding groove 14, and a plurality of ring pieces 16 are fixedly connected to the outer surface of the bag body 5; the sliding blocks 15 located at the same horizontal position are fixedly connected to the same ring piece 16. By replacing the telescopic rod 7 with the sliding groove 14, a larger volume can be provided for the expansion of the bag body 5. The arrangement of the ring piece 16 can provide support for the bag body 5 and resist the deformation of the bag body 5 under negative pressure, that is, it ensures that when a negative pressure is formed inside the bag body 5, the volume change of the bag body 5 is small.

[0068] Specifically, in the state where the telescopic cylinder 32 is contracted, the ring pieces 16 are arranged at intervals from each other.

[0069] Such as Figures 5 to 9 As shown, due to the limitation of the sliding block 15 or the telescopic rod 7, the pressing plate 6 cannot move to the bottom of the glue storage tank 1. Therefore, a first cylinder body 62 and a second cylinder body 63 are arranged on the pressing plate 6, and the first cylinder body 62 and the second cylinder body 63 can extend into the bottom of the glue storage tank 1 as much as possible to discharge the center line glue as much as possible. Improve the discharge rate of the center line glue.

[0070] In one embodiment, a first clamping strip 18 is formed on the side surface of the telescopic glue storage tank 1 near the edge of the opening 11, and a second clamping strip 22 is provided at the edge of the lower end surface of the cover body 2. The upper end surface of the second clamping strip 22 can be abutted against the lower end surface of the first clamping strip 18; the edge of the opening 11 is abutted against the lower end surface of the cover body 2 through a sealing ring 9. The arrangement of the first clamping strip 18 and the second clamping strip 22 realizes the detachable connection between the opening 11 and the cover body 2, and the first clamping strip 18 and the second clamping strip 22 are simple in structure, practical and reliable.

[0071] Specifically, the first clamping strip 18 has an inclined section and a horizontal section, and rollers are provided on the second clamping strip 22; when the cover body 2 is closed on the opening 11, the rollers of the second clamping strip 22 are abutted against the lower end surface of the inclined section of the first clamping strip 18, and the cover body 2 is rotated so that the rollers move downward along the inclined section to the horizontal section. Since the rollers move downward, the cover body 2 is driven to move downward, so that the abutting pressure between the cover body 2 and the sealing ring 9 is increased, and the sealing effect of the sealing ring 9 on the cover body 2 and the edge of the opening 11 is improved.

[0072] In one embodiment, the outside of the glue storage tank 1 is coated with a heat insulation layer 8, and a heating wire 81 and / or a water pipe 82 are arranged in the heat insulation layer 8. The heating wire 81 and the water pipe 82 can well control the temperature of the center line glue in the glue storage tank 1.

[0073] Specifically, through the cooperation of the heating wire 81 and the water pipe 82, the storage temperature of the center line glue in the glue storage tank 1 is controlled at 5-25 °C. Avoid high temperature accelerating the oxidation of the colloid or low temperature causing solidification and stratification.

[0074] Specifically, a temperature sensor 83 is provided on the outer side surface of the glue storage tank 1. The water pipe 82 is connected to an external cooling water source and is spirally wound around the outer side surface of the glue storage tank 1. The water temperature in the water pipe 82 can be adjusted according to the situation, so as to ensure that the temperature of the midline glue in the glue storage tank 1 is within a predetermined temperature range.

[0075] The temperature sensor 83 is connected to a processor, and the processor is connected to a display. A pump body and a water temperature sensor are provided on the water pipe 82, and the heating wire 81 is connected to a switch; the display, the pump body, the temperature sensor 83, the water temperature sensor, and the switch are all electrically connected to the processor. Based on the temperature feedback by the temperature sensor 83, the processor can automatically adjust the pump body power of the water pipe 82 and / or the on-off state of the switch. The heating wire 81 is wound along the winding direction of the water pipe 82.
