Description

Technical Field

[0001] The invention relates to the field of dust filter bag production and processing, and more specifically, to a heating and shaping device for producing dust filter bags based on intelligent temperature control technology. Background Art

[0002] Dust filter bags are a kind of high-efficiency dust removal filter material. Dust filter bags are made of polyester staple fiber, PPS fiber, polypropylene, aramid fiber, and nylon fiber. The service life is generally 2-4 years. They have good air permeability, high dust collection rate, easy cleaning and other excellent properties.

[0003] Dust filter bags need to be heat-set during the production process. The purpose of heat setting is to eliminate the residual stress in the filter bag processing process, so that the size of the filter bag is stable and the surface is flat. The existing heat setting method generally adopts the method of setting the dust filter bag on a setting sleeve, and uses the contact between the heated setting sleeve and the dust filter bag to heat and set it. However, it is difficult to monitor and timely control the heating temperature of the setting sleeve. When the heating temperature is too high, it is difficult to take timely measures to quickly cool it down, which can easily cause damage to the dust filter bag. In addition, the uniform size of the setting sleeve is difficult to adapt to the dust filter bags with different inner diameters. Therefore, for dust filter bags with different sizes, it is often necessary to replace the setting sleeve, which is a cumbersome operation.

[0004] To this end, we propose a heating and shaping equipment for dust filter bag production that has a wide range of applications and is based on intelligent temperature control technology to effectively solve some problems existing in the prior art. Summary of the invention

[0005] The purpose of the present invention is to solve the problems that it is difficult to monitor and timely control the heating temperature of the shaping sleeve and the poor adaptability of the existing shaping sleeve. Compared with the existing technology, a heating shaping device for dust filter bag production based on intelligent temperature control technology is provided. By replacing the traditional shaping sleeve with an exhaust roller and a matching structure of multiple shaping roller sleeves, the dust filter bag is sleeved on the exhaust roller and limited during operation, and the high-temperature gas is introduced into the exhaust roller by an exhaust pipe. The high-temperature gas is evenly introduced into the inner side of the dust filter bag through the exhaust hole, and the gas enters multiple inner shaping rollers synchronously. The outer elastic sleeve is expanded outward and contacts with the inner end wall of the dust filter bag. It is suitable for dust filter bags of different sizes. The dust filter bag is rolled and shaped by the rotating shaping roller sleeve and the high-temperature gas exported, and the temperature is double-monitored in real time by using temperature sensor 2 and temperature sensor 1. When the temperature in the exhaust roller is too high, low-temperature air is immediately introduced, and the heat at the dust filter bag is quickly dissipated outward by using the flowing low-temperature gas.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The heating and shaping equipment for the production of dust removal filter bags based on intelligent temperature control technology includes a workbench. On both sides of the upper end of the workbench, there are shaping sleeves for sleeving dust removal filter bags. An insulating frame covering the outside of a pair of shaping sleeves is also installed on the upper end of the workbench. The bottom end of the shaping sleeve is fixedly connected to a rotating cylinder rotatably connected to the upper end wall of the workbench. The bottom end of the rotating cylinder is connected to a fixed column fixed on the bottom end wall of the workbench through a rotary joint. The fixed column, the rotating cylinder, and the inside of the shaping sleeve are connected in communication. The workbench is fixedly installed with a heating box at the middle position between a pair of shaping sleeves. A pair of heating tubes and a temperature sensor II are installed inside the heating box. A blower connected to the inside of the heating box is also installed on the upper end of the workbench. A pair of exhaust pipes respectively connected to the fixed column are arranged inside the heating box. The shaping sleeve includes an exhaust roller fixedly connected to the upper end of the rotating cylinder. A plurality of shaping roller sleeves are annularly distributed on the outer end wall of the exhaust roller. The shaping roller sleeve includes an inner shaping roller connected in communication with the inside of the exhaust roller. An outer elastic sleeve connected in communication with its inside is covered outside the inner shaping roller. An inner positioning rod with the bottom connected to the inner wall of the fixed column is sleeved inside the exhaust roller. A temperature sensor I is arranged on the end wall of the inner positioning rod.

[0008] Further, a transmission gear I is fixedly sleeved on the outer end wall of the rotating cylinder above the workbench. A driving motor is fixedly installed on the bottom end wall of the workbench. The driving end of the driving motor penetrates through the workbench and is fixedly connected to a transmission gear II meshing with the transmission gear I. A protective cover covering the transmission gear I and the transmission gear II is installed on the upper end wall of the workbench. The rotation of the exhaust roller is realized by using a transmission chain. The rotating cylinder and the fixed column are connected through a rotary joint, and the two work independently without affecting each other.

[0009] Further, the exhaust roller is a hollow sleeve structure with openings at both the upper and lower ends. A plurality of exhaust holes are opened on the end wall of the exhaust roller. Ventilation cavities are opened on the end wall of the inner shaping roller connected to the exhaust roller and on the end wall facing the shaping roller sleeve. The heated gas is introduced into the inside of the exhaust roller through the exhaust pipe. The high-temperature gas is evenly introduced into the inner side of the dust removal filter bag through the exhaust holes on the exhaust roller. While the gas is being introduced, the gas simultaneously enters into a plurality of inner shaping rollers. The outer elastic sleeve is expanded and expanded outwards and abuts against the inner end wall of the dust removal filter bag.

[0010] Further, both the exhaust roller and the inner shaping roller are made of rigid heat-conducting materials, and the outer elastic sleeve is made of elastic heat-conducting materials. By introducing gas, the outer elastic sleeve is expanded and expanded outwards to increase the outer diameter length of the shaping sleeve.

[0011] Furthermore, a gas guide pipe extending to the bottom of the exhaust roller is installed at the ventilation cavity where the inner shaping roller is connected to the exhaust roller. A control valve is installed inside the gas guide pipe, and the gas guide pipe is fixedly connected to the inner wall of the exhaust roller. Compared with supplying gas to the inner shaping roller through the flowing exhaust roller, using the gas guide pipe for gas diversion can, to a certain extent, effectively prevent the outer elastic sleeve from deforming excessively during the rotation and extrusion with the inner wall of the dust removal filter bag, thus affecting the extrusion force on the dust removal filter bag. Therefore, the inflated outer elastic sleeve can be better used to knead and press the dust removal filter bag.

[0012] Furthermore, a magnetic rotating disk rotatably connected to the top wall of the exhaust roller is fixedly installed at the top end of the inner positioning rod. A magnetic positioning disk matching the magnetic rotating disk is attached to the top wall of the dust removal filter bag. The magnetic positioning disk and the magnetic rotating disk are magnetically attracted to each other. After the dust removal filter bag is sleeved on the exhaust roller, a plurality of expanding shaping roller sleeves are used to support the inner wall of the dust removal filter bag. Then, the magnetic positioning disk is attached to the top of the dust removal filter bag. By using the magnetic attraction and positioning performance of the magnetic positioning disk and the magnetic rotating disk, the top of the dust removal filter bag can be fixed. During the rotation of the exhaust roller, the top of the dust removal filter bag does not twist with it.

[0013] Furthermore, a lower clamping member for limiting the bottom of the dust removal filter bag is also installed on the workbench. The lower end of the lower clamping member is connected to the protective cover.

[0014] Furthermore, the lower clamping member includes a pair of telescopic rods fixed to the protective cover. The top ends of the pair of telescopic rods are fixed with a clamping sleeve sleeved outside the exhaust roller. A plurality of clamping pieces are annularly distributed on the inner end wall of the clamping sleeve. The clamping pieces are of U-shaped structure.

[0015] Optionally, the clamping piece includes an elastic piece connected to the clamping sleeve. The outer end of the elastic piece is coated with a flexible pad, and a magnetic sheet is provided on the elastic piece. An electromagnet matching the magnetic sheet is installed inside the clamping sleeve. After the dust removal filter bag is sleeved on the exhaust roller, the dust removal filter bag is clamped between the clamping sleeve and the clamping piece. When the electromagnet is started, the clamping piece moves towards the clamping sleeve side, thereby squeezing and clamping the bottom of the dust removal filter bag. By adjusting the telescopic rod, the up and down movement of the clamping sleeve can be realized, so as to be suitable for clamping dust removal filter bags of different lengths.

[0016] Optionally, a ventilation pipe is externally connected to a pair of exhaust pipes. Heat collecting covers are respectively arranged on a pair of exhaust rollers. A circulation pipe connected to the fan is connected to the heat collecting cover. Control air valves are installed on the inner wall of the exhaust pipe near the heating box and inside the ventilation pipe. By adding the ventilation pipe, when the temperature sensor detects that the temperature inside the exhaust roller is too high, the control air valve arranged at the end where the exhaust pipe is connected to the heating box is disconnected, and the control air valve inside the ventilation pipe is opened. By introducing unheated gas into the exhaust roller, it is beneficial to quickly cool the dust removal filter bag with too high temperature, and use the flowing low-temperature gas to transfer the heat outwards, shortening the cooling time.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This scheme is to distribute multiple shaping roller sleeves in an annular manner on the outer end wall of the exhaust roller with multiple exhaust holes. The shaping roller sleeve is composed of an inner shaping roller and an outer elastic sleeve. When working, the dust filter bag is sleeved on the exhaust roller and limited. The exhaust pipe is used to introduce high-temperature gas into the exhaust roller. The high-temperature gas is evenly introduced into the inner side of the dust filter bag through the exhaust holes. While the gas is introduced, the gas simultaneously enters into the multiple inner shaping rollers. The outer elastic sleeve expands outward and contacts the inner end wall of the dust filter bag. It is suitable for positioning and processing dust filter bags of different sizes. The rotating shaping roller sleeve is used to roll and shape the dust filter bag with the high-temperature gas, which plays an ironing role. At the same time, the temperature sensor 2 and the temperature sensor 1 are used to monitor the temperature of the heating box and the inner side of the exhaust roller in real time. When the temperature inside the exhaust roller is too high, low-temperature air is immediately introduced, and the flowing low-temperature gas is used to transfer the heat to the outside, which is conducive to timely and rapid cooling of the dust filter bag with too high temperature.

[0019] (2) After the dust filter bag is put on the exhaust roller, a magnetic positioning plate is placed on the top of the dust filter bag. The magnetic positioning performance of the magnetic positioning plate and the magnetic rotating plate is used to fix the top of the dust filter bag. During the rotation of the exhaust roller, the top of the dust filter bag does not twist with it. The dust filter bag is clamped between the clamping sleeve and the clamping plate. The electromagnet is started and the clamping plate moves to one side of the clamping sleeve, thereby squeezing and clamping the bottom of the dust filter bag. The telescopic rod is adjusted to realize the up and down movement of the clamping sleeve, which is suitable for clamping dust filter bags of different lengths. Since the clamping plate and the outer elastic sleeve have a certain elasticity, it is not easy to cause a jamming problem during the rotation of the shaping roller sleeve along the inner wall of the dust filter bag.

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] The present invention discloses a heating and shaping device for the production of dust removal filter bags based on intelligent temperature control technology. Please refer to Figures 1-5, including a workbench 2. On both sides of the upper end of the workbench 2, there are shaping sleeves for sleeving the dust removal filter bag 1. On the upper end of the workbench 2, there is also a heat insulation frame 3 covering the outside of a pair of shaping sleeves. The bottom end of the shaping sleeve is fixedly connected to a rotating cylinder 6 rotatably connected to the upper end wall of the workbench 2. The bottom end of the rotating cylinder 6 is connected through a rotary joint to a fixed column 7 fixed on the bottom end wall of the workbench 2. The fixed column 7, the rotating cylinder 6, and the inside of the shaping sleeve are connected in communication. At the middle position between a pair of shaping sleeves on the workbench 2, there is a heating box 13 fixedly installed. Inside the heating box 13, there are a pair of heating tubes 15 and a temperature sensor two 16. On the upper end of the workbench 2, there is also a blower 14 connected in communication with the inside of the heating box 13. Inside the heating box 13, there are a pair of exhaust pipes 8 respectively connected to the fixed column 7. On the outer end wall of the rotating cylinder 6 above the workbench 2, there is a driving gear one fixedly sleeved. On the bottom end wall of the workbench 2, there is a driving motor fixedly installed. The driving end of the driving motor penetrates through the workbench 2 and is fixedly connected to a driving gear two meshing with the driving gear one. On the upper end wall of the workbench 2, there is a protective cover covering the driving gear one and the driving gear two. The rotation of the exhaust roller 4 is realized by using a transmission chain group. The rotating cylinder 6 and the fixed column 7 are connected through a rotary joint, and the two work independently without affecting each other.

[0034] Please refer to Figures 5-8 , the shaping sleeve includes an exhaust roller 4 fixedly connected to the upper end of the rotating cylinder 6. On the outer end wall of the exhaust roller 4, there are a plurality of shaping roller sleeves 5 distributed annularly. The shaping roller sleeve 5 includes an inner shaping roller 51 connected in communication with the inside of the exhaust roller 4. An outer elastic sleeve 52 covering the outside of the inner shaping roller 51 is connected in communication with its inside. The exhaust roller 4 is a hollow sleeve structure with openings at both the upper and lower ends. On the end wall of the exhaust roller 4, there are a plurality of exhaust holes. The end wall of the inner shaping roller 51 connected to the exhaust roller 4 and the end wall facing the shaping roller sleeve 5 are both provided with ventilation cavities. The heated gas is introduced into the inside of the exhaust roller 4 through the exhaust pipe 8. The high-temperature gas is evenly introduced into the inner side of the dust removal filter bag 1 through the exhaust holes on the exhaust roller 4. While introducing the gas, the gas simultaneously enters into a plurality of inner shaping rollers 51. The outer elastic sleeve 52 is expanded outwards and abuts against the inner end wall of the dust removal filter bag 1. After positioning the upper and lower parts of the dust removal filter bag 1, the dust removal filter bag 1 is kept in a stable state. The rotating shaping roller sleeve 5 is used to cooperate with the evenly and continuously discharged high-temperature gas to roll-press the dust removal filter bag 1, playing an ironing and shaping role on the dust removal filter bag 1.

[0035] The exhaust roller 4 and the inner sizing roller 51 are both made of a rigid heat-conducting material, and the outer elastic sleeve 52 is made of an elastic heat-conducting material. By introducing gas, the outer elastic sleeve 52 expands outwards, expanding the outer diameter length of the sizing sleeve, so as to be applicable to processing the dust removal filter bag 1 within a certain range of sizes. The exhaust roller 4, the inner sizing roller 51, and the outer elastic sleeve 52 all have heat-conducting properties. Thus, during the process of high-temperature gas flow, the sizing roller sleeve 5 has a certain temperature, which, combined with the uniformly and continuously exported high-temperature gas, effectively improves the hot pressing and sizing effect on the dust removal filter bag 1. Moreover, the heater is not directly used to heat the exhaust roller 4 and the sizing roller sleeve 5 to avoid excessive shell temperature, which may damage the sizing effect on the dust removal filter bag 1 in the case of insufficient heat dissipation in time.

[0036] At the air vent cavity where the inner sizing roller 51 is connected to the exhaust roller 4, a gas guide pipe extending to the bottom of the exhaust roller 4 is also installed. A control valve is installed inside the gas guide pipe, and the gas guide pipe is fixedly connected to the inner wall of the exhaust roller 4. Compared with supplying gas to the inner sizing roller 51 through the flowing exhaust roller 4, using the gas guide pipe for gas diversion can, to a certain extent, effectively prevent the outer elastic sleeve 52 from deforming excessively during the rotation and extrusion with the inner wall of the dust removal filter bag 1, thus affecting the extrusion force on the dust removal filter bag 1, and enabling better kneading of the dust removal filter bag 1 by the inflated outer elastic sleeve 52.

[0037] An inner positioning rod 9 whose bottom is connected to the inner wall of the fixed column 7 is sleeved inside the exhaust roller 4. A temperature sensor 11 is provided on the end wall of the inner positioning rod 9, which is used to monitor the temperature inside the exhaust roller 4. The temperature sensor 16 installed inside the heating box 13 is used to monitor the heating temperature of the heating pipe 15, playing a dual temperature control role. By controlling the heating level and the number of heating elements of the heating pipe 15, the air discharged into the exhaust roller 4 is regulated. When the temperature inside the exhaust roller 4 is too high, the introduction of high-temperature gas is immediately stopped, and the heating pipe 15 is turned off. The heat is transferred outwards by the flowing non-continuously heated gas, which is beneficial to quickly cooling the dust removal filter bag 1 with too high a temperature and shortening the cooling time.

[0038] Embodiment 2:

[0039] This embodiment is used to solve the problem of vertically positioning the dust removal filter bag 1. During the rotation of the exhaust roller 4, it is necessary to limit the dust removal filter bag 1, and the two rotate relative to each other with friction to improve the heating and sizing effect on the dust removal filter bag 1. On the basis of Embodiment 1, this embodiment adds a magnetically rotating disk 10, a magnetic positioning disk 12, and a lower clamping member 17 that cooperate with each other vertically, specifically as follows:

[0040] Please refer to Figures 5-6, a magnetic rotating disk 10 rotatably connected to the top wall of the exhaust roller 4 is fixedly installed at the top end of the inner positioning rod 9. A magnetic positioning disk 12 matching the magnetic rotating disk 10 is attached to the top wall of the dust removal filter bag 1. The magnetic positioning disk 12 and the magnetic rotating disk 10 are magnetically attracted to each other. After the dust removal filter bag 1 is sleeved on the exhaust roller 4, a plurality of expanding shaping roller sleeves 5 are used to support the inner wall of the dust removal filter bag 1. Then, the magnetic positioning disk 12 is attached to the top of the dust removal filter bag 1. By utilizing the magnetic attraction and positioning performance of the magnetic positioning disk 12 and the magnetic rotating disk 10, the top of the dust removal filter bag 1 is fixed. During the rotation of the exhaust roller 4, the top of the dust removal filter bag 1 does not twist with it;

[0041] Please refer to Figure 4 and Figure 8 , a lower clamping member 17 for limiting the bottom of the dust removal filter bag 1 is also installed on the workbench 2. The lower end of the lower clamping member 17 is connected to the protective cover. The lower clamping member 17 includes a pair of telescopic rods 173 fixed to the protective cover. A clamping sleeve 171 sleeved outside the exhaust roller 4 is fixed to the top ends of the pair of telescopic rods 173. A plurality of clamping pieces 172 are annularly distributed on the inner end wall of the clamping sleeve 171. The clamping pieces 172 are of U-shaped structure. The clamping pieces 172 include elastic pieces connected to the clamping sleeve 171. A flexible pad is coated on the outer end of the elastic piece, and a magnetic sheet is provided on the elastic piece. An electromagnet matching the magnetic sheet is installed inside the clamping sleeve 171. After the dust removal filter bag 1 is sleeved on the exhaust roller 4, the dust removal filter bag 1 is clamped between the clamping sleeve 171 and the clamping pieces 172. The electromagnet is started, and the clamping pieces 172 move towards the clamping sleeve 171 side, thereby squeezing and clamping the bottom of the dust removal filter bag 1. The telescopic rods 173 are adjusted to realize the up and down movement of the clamping sleeve 171, so as to be applicable to clamping dust removal filter bags 1 of different lengths. Since the clamping pieces 172 and the outer elastic sleeve 52 both have a certain elasticity, the problem of tape jamming is not easily caused during the rotation of the shaping roller sleeve 5 along the inner wall of the dust removal filter bag 1.

[0042] Embodiment 3:

[0043] The difference between this embodiment and Embodiment 2 is that: on the basis of Embodiment 2, a ventilation pipe 81 is added to 8, and the heat insulation frame 3 is replaced with a heat collecting cover 18, specifically as follows:

[0044] Please refer to Figure 9, a pair of exhaust pipes 8 are also externally connected with ventilation pipes 81. Heat collecting covers 18 are respectively arranged on a pair of exhaust rollers 4. A circulating pipe connected to the fan 14 is connected to the heat collecting cover 18. Control air valves are installed on the inner wall of the exhaust pipe 8 near one end of the heating box 13 and inside the ventilation pipe 81. By adding the ventilation pipe 81, when the temperature sensor 11 detects that the temperature inside the exhaust roller 4 is too high, the control air valve arranged at the end where the exhaust pipe 8 is connected to the heating box 13 is disconnected, and the control air valve inside the ventilation pipe 81 is opened. By introducing unheated gas into the exhaust roller 4, it is beneficial to quickly cool down the dust removal filter bag 1 with too high temperature in a timely manner, transfer the heat outward by using the flowing low-temperature gas, shorten the cooling time, and replace the heat insulation frame 3 with a separately arranged heat collecting cover 18. The space of the heat collecting cover 18 is smaller than that of the heat insulation frame 3, improving the heat collecting effect. The circulating pipe can re-introduce the high-temperature gas into the heating box 13 through the fan 14, or directly discharge the high-temperature gas outward. An externally discharged pipe is added to the circulating pipe. This is the prior art, and the gas diversion is carried out according to the actual working needs.

[0045] Combined with Embodiments 1, 2, and 3, the usage method of the heating and shaping equipment for the production of dust removal filter bags based on intelligent temperature control technology includes the following steps:

[0046] S1. Sleeve the dust removal filter bag 1 to be processed on the exhaust roller 4. Use the cooperation of the magnetic rotating disk 10 and the magnetic positioning disk 12 to limit the top of the dust removal filter bag 1, and then use the lower clamping member 17 to limit the bottom of the dust removal filter bag 1.

[0047] S2. Start the heating pipe 15 and the fan 14, introduce the high-temperature gas into the exhaust roller 4 through the exhaust pipe 8. The high-temperature gas is evenly introduced into the inner side of the dust removal filter bag 1 through the exhaust holes on the exhaust roller 4. At the same time, the gas synchronously enters into a plurality of inner shaping rollers 51, and the outer elastic sleeve 52 is expanded outward and abuts against the inner end wall of the dust removal filter bag 1. Use the rotating shaping roller sleeve 5 and the evenly and continuously discharged high-temperature gas to roll-press the dust removal filter bag 1 and iron and shape the dust removal filter bag 1.

[0048] S3. Use the temperature sensor 2 16 and the temperature sensor 1 11 to respectively monitor the temperature inside the heating box 13 and the exhaust roller 4 in real time. By controlling the heating level and the number of heating elements of the heating pipe 15, the intelligent regulation of the air temperature discharged into the exhaust roller 4 is realized. When the temperature inside the exhaust roller 4 is too high, immediately stop introducing the high-temperature gas, open the control air valve inside the ventilation pipe 81, and use the flowing low-temperature gas to transfer the heat at the dust removal filter bag 1 outward, which is beneficial to quickly cool down the dust removal filter bag 1 with too high temperature in a timely manner.

[0049] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making equivalent substitutions or changes according to the technical solution and its improved concept of the present invention, shall be covered by the protection scope of the present invention.
