Description

Technical Field

[0001] The utility model relates to the technical field of daily paper packaging, in particular to a negative pressure integrated device for origami. Background Art

[0002] Paper mills manufacture household paper through papermaking machinery. If the formed household paper is to flow into the market, it needs to be packaged. The existing packaging methods include cutting the sheets of household paper as needed and then rolling them up or folding the household paper into packages after cutting them as needed. Whether rolling or packaging in packages, a vacuum pump is used to adsorb the sheets of household paper onto the rewinding roller, and then roll the paper or cut and fold the paper. Therefore, vacuum pumps are indispensable in the field of household paper packaging. For example: CN2279264Y, title: Rewinding and rewinding device for coreless roll household paper, discloses "a rewinding plate 5 having a cross section that is basically an involute and an air jet mechanism with a nozzle facing between the rewinding plate 5 and the roller 31". Although the patent discloses the jet mechanism, it does not give the specific working mode and jet method of the jet mechanism. Secondly, if the jet mechanism is used in the field of household paper packaging, it will inevitably cause cotton wool and papermaking on the household paper to block the pipeline of the jet mechanism, increase the noise of the entire equipment, and affect the physical and mental health of workers. Secondly, the household paper packaging process is in a dry environment, and fire is prone to occur when encountering open flames.

[0003] Therefore, there is an urgent need for a vacuum pump that reduces the risk of jet mechanism blockage, reduces noise, and avoids fire. Utility Model Content

[0015] The utility model of a negative pressure integrated device for origami has the following beneficial effects compared with the prior art:

[0016] (1) When the flocs and dust on the household paper adsorbed by the vacuum pump enter the cyclone from the air inlet, they first enter the second cavity. After some flocs and dust enter the second cavity, they enter the blanking barrel connected to the second cavity under the action of gravity, thereby preventing the flocs and dust from clogging the vacuum pump. Secondly, a filter is also arranged between the first cavity and the second cavity. When the gas continues to reach the first cavity from the second cavity under the action of the vacuum pump, it is finally discharged from the cyclone through the air outlet connected to the first cavity. When the gas enters the first cavity from the second cavity, the flocs and dust in the gas are filtered again through the filter, thereby minimizing the impurities in the gas discharged from the air outlet, thereby achieving a dust prevention effect.

[0017] (2) In order to ensure that the first cavity is connected to the second cavity, an air vent is set on the partition. The gas entering from the air inlet passes through the second cavity to reach the first cavity and is finally discharged from the air outlet. In order to perform secondary filtration on the gas, we set a circular filter around the air vent. At this time, the gas enters the air outlet through the side wall of the cylindrical filter, and the filter fully filters the gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model.

Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3As shown, a negative pressure integrated device for origami includes a vacuum pump 1, a blanking barrel 21 and a cyclone barrel 22, a partition 221 is arranged in the cyclone barrel 21, the partition 221 divides the cyclone barrel 21 into a first cavity 31 and a second cavity 32, the first cavity 31 and the second cavity 32 are connected, the blanking barrel 21 is arranged at one end of the second cavity 32 away from the first cavity 31, and the blanking barrel 21 is connected to the second cavity 32; the second cavity 32 is connected to an air inlet 23, the first cavity 31 is connected to an air outlet 24, a filter screen 222 is arranged between the air inlet 23 and the air outlet 24, and the air outlet 24 is connected to the vacuum pump 1. When the flocs, dust, etc. on the daily paper adsorbed by the vacuum pump 1 enter the cyclone 22 from the air inlet 23, they first enter the second cavity 32. After some flocs and dust enter the second cavity 32, they enter the blanking barrel 21 connected to the second cavity 32 under the action of gravity, thereby preventing the flocs and dust from clogging the vacuum pump; secondly, a filter 222 is also provided between the first cavity 31 and the second cavity 32. When the gas continues to reach the first cavity 31 from the second cavity 32 under the action of the vacuum pump 1, it is finally discharged from the cyclone 21 due to the air outlet 24 connected to the first cavity 31. When the gas enters the first cavity 31 from the second cavity 32, the flocs and dust in the gas are filtered again through the filter 222, thereby minimizing the impurities in the gas discharged from the air outlet 24, thereby achieving a dust prevention effect.

[0025] The partition 221 is provided with a vent 223, and the filter 222 is cylindrical, and one end of the filter 222 is arranged in cooperation with the vent 223. In order to ensure that the first cavity 31 is connected with the second cavity 32, the vent 223 is arranged on the partition 221, and the gas entering from the air inlet 23 passes through the second cavity 32 to reach the first cavity 31, and is finally discharged from the gas outlet 24. In order to perform secondary filtration on the gas, we set a round filter 222 around the vent 223. At this time, the gas enters the gas outlet 24 through the side wall of the cylindrical filter 222, and the filter 222 fully filters the gas.

[0026] One end of the filter screen 222 that cooperates with the vent 223 is disposed on the partition 221, and a sealing strip 224 is disposed between the filter screen 222 and the partition 221. In order to increase the sealing between the filter screen 222 and the partition 221, a sealing strip 224 is added between the filter screen 222 and the partition 221.

[0027] The first cavity 31 is provided with a dust cover 25 at one end away from the second cavity 32, and the dust cover 25 is buckled on the end of the cyclone 22 away from the blanking barrel 21, and the end of the filter 222 away from the vent 223 is provided on the dust cover 25. In order to facilitate the cleaning or replacement of the filter 222, the filter 222 is provided on the dust cover 25, and the dust cover 25 is buckled on the end of the cyclone 22 away from the blanking barrel 21. When replacing or cleaning the filter 222, it is only necessary to remove the dust cover 25 from the cyclone 22. In order to ensure that the gas in the cyclone 22 does not leak out, the dust cover 25 and the cyclone 22 are sealed.

[0028] The vent 223 is provided with a filter tube 225, one end of which is located in the first cavity 31, and the other end of which is located in the second cavity 32. The filter tube 225 is provided on the vent 223, which increases the difficulty for some flocs and dust to reach the first cavity 31 from the second cavity 32 through the filter tube 225.

[0029] The inner diameter of the second cavity 32 gradually decreases from the end away from the blanking barrel 21 to the end connected to the blanking barrel 21. In order to make the floccules and dust entering the second cavity 32 from the air inlet 23 fall into the blanking barrel 21 after the second cavity 32 descends, the inner diameter of the second cavity 32 gradually decreases from the end away from the blanking barrel 21 to the end connected to the blanking barrel 21, and the airflow gradually forms a cyclone, which increases the time of the gas in the second cavity 32, and the probability of floccules and dust falling into the blanking barrel 21 increases.

[0030] It also includes a water tank 4, which is provided with a water inlet 41, a water outlet 43 and an overflow port 42. The water outlet 43 is provided at the bottom of the water tank 4, and the water inlet 41 and the overflow port 42 are provided at one end of the water tank 4 away from the water outlet 43. When the household paper packaging equipment is packaging the household paper, once the household paper burns, the fire will increase instantly under the action of the vacuum pump 1. In order to avoid fire, the water tank 4 is filled with water. Once a fire occurs, the water is discharged from the water outlet 43 for fire extinguishing.

[0031] The vacuum pump 1 comprises a vacuum pump air intake port 11, a vacuum pump air outlet 12 and a vacuum pump heat dissipation port 13. An air duct 5 is arranged between the vacuum pump air intake port 11 and the air outlet 24. The vacuum pump air outlet 12 is connected to an air outlet silencer 6. The vacuum pump heat dissipation port 13 is connected to a heat dissipation box 7. The heat dissipation box 7 is arranged above the water tank 4. The water in the water tank 4 has a large specific heat capacity, which is conducive to absorbing the heat in the heat dissipation box 7 and helping the heat dissipation box 7 to dissipate heat and reduce the temperature.

[0032] It also includes a bracket 8 and a box 9, the box 9 is arranged on the bracket 8, and the vacuum pump 1, the blanking cylinder 21, the water tank 4, and the heat dissipation box 7 are all arranged in the box 9. Silencing cotton is added to the box 9 to reduce internal noise, and universal wheels are added to the bottom of the bracket 8 to facilitate the movement of the entire box. Example 2

[0033] In the first embodiment, the filter screen 222 is a barrel-shaped structure. The barrel-shaped filter screen 222 has poor sealing performance, is relatively complex to produce, and has high costs, which is not conducive to mass production. In order to reduce the difficulty of assembly, reduce production costs, and improve sealing performance, the present embodiment is different from the first embodiment as follows:

[0034] like Figure 4 As shown, the partition 221 is provided with a vent 223, and the filter 222 covers the vent 223. The filter 222 is planar and directly covers the vent 223. A traction rod 251 is connected between the filter 222 and the dust cover 25, and the filter 222 can be pulled out of the cyclone 22 along with the dust cover 25 for cleaning or replacement.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
