Detailed Description

Fig. 1 shows a specific embodiment of the air-tight material painting machine between the wallboard joints of the controlled atmosphere fresh-keeping warehouse provided by the utility model, which comprises a frame 1, wherein the mechanism arranged on the frame 1 comprises a traveling mechanism 2, a feeding mechanism 3, a cloth feeding mechanism 4 and a rolling mechanism 5;

the frame 1 comprises a frame, as shown in fig. 2a to 2c, the frame comprises a flat plate 11 and two vertical plates 12 connected downwards at two side edges of the flat plate 11, and the aforementioned travelling mechanism 2, feeding mechanism 3, cloth feeding mechanism 4 and rolling mechanism 5 are all mounted on the frame 1.

Referring to fig. 1, the running mechanism 2 is a crawler running mechanism, the crawler running mechanism includes two sets of main crawler devices and motors, the motors are fixed on the frame, each set of the main crawler device includes a driving wheel 21, a driven wheel 22 and a main crawler 23, the driving wheel 21 and the driven wheel 22 are respectively arranged at the rear end and the front end of a side vertical plate 12 of the frame 1, the driving wheel 21 is connected with the motor 24, the wheel axle of the driven wheel 22 is fixed on the vertical plate 12 through a bearing, the driving wheel is fixed on the vertical plate 12 and is connected with the motor 24 also fixed on the vertical plate 12, the main crawler 23 is fixed on the driving wheel 21 and the driven wheel 22, the two main crawlers of the two sets of main crawler devices are respectively located at the outer sides of the two side vertical plates of the frame 1 through the structure, the permanent magnet blocks 231 are fixed to the outer surface of the main track 23, so that the painting machine can be used for painting airtight materials in wall seams by walking on a metal wall surface. The stress condition of the painting machine when vertically walking on the wall surface is as shown in fig. 8a and fig. 8b, the suction force F of the magnet block on the crawler belt enables the painting machine to have positive pressure, positive pressure and friction coefficient, thereby generating a friction force N opposite to the moving direction, when the painting machine vertically walks upwards on the wall surface, the force to be overcome is as follows: 1. the torque of the distance from the center of mass of the total mass G of the machine to the wall surface; 2. the applicator slips under the weight of the applicator. The following are discussed separately:

A. the total mass G of the machine is the torque of the distance L from the center of mass to the wall surface.

As shown in fig. 8b, the magnet attracting the wall at the bottom of the painting machine is taken as 0 point, and the moment arm Ln is larger and the moment Fn × Ln is larger as the force arm Ln is higher. In order to ensure the safety of the machine walking on the wall surface, a set of magnet attraction force moments, namely a set of moments of force arms of the vertical distance from attraction force of each permanent magnet block magnet to 0 point, is needed to balance the gravity center G of the machine with the vertical distance L from the gravity center of the machine to 0 point (the distance from G to the wall surface).

The total mass of the brushing machine is G, the vertical distance from the mass center of the brushing machine to a point 0 is L, the overturning moment F' is G.L, so that the brushing machine can safely vertically walk on the wall surface, and the requirements that:

G·L＝F1*L1+F2*L2+F3*L3+.....

+Fn*Ln＝F*(L1+L2+......+Ln) (1)

wherein: f1, F2, Fn, each magnet attracting force;

l1, L2, L.. Ln, the vertical distance from each magnet position to point 0;

in the formula: g-total mass of the brushing machine; l-the vertical distance from the centroid of the applicator to point 0.

F1, F2, … ….. Fn-attraction force of each magnet block; in the utility model, the magnet blocks on the caterpillar track are equal in size, and the suction force F of each magnet block is also equal, therefore,

F1＝F2＝……..Fn＝F (2)

the stress analysis shows that the heavier the total mass of the brushing machine G is, the larger the vertical distance L from the center of mass to the 0 point is, and the larger the overturning moment F' of the brushing machine is. The more torque is required to overcome. This is also an important factor to consider in the later design.

B. The magnetic force of the brushing machine also overcomes the gliding of the weight function;

N＝-G＝∑F*K (3)

in the formula: n-overcoming the gliding friction force of the brushing machine;

-G-total mass of the coater;

sigma F-set of magnet attraction forces;

k-coefficient of friction;

considering from the aspect of the gliding force, the attraction force of the magnet can overcome the gliding of the brushing machine under the action of gravity and increase the friction force to enable the brushing machine to climb upwards, but if the attraction force of the magnet is too large, the total power of the walking motor can be increased, so that the total weight of the machine is increased, and the crawling of the brushing machine can also be influenced.

An extrusion piston 311 is arranged in the material cylinder 31, a piston 0 type sealing ring 311a arranged on the extrusion piston 311 and the inner wall of the material cylinder form a sealing structure, a push disc 312 is arranged at the rear part of the extrusion piston 311, one end of a screw rod 313 is connected to the push disc 312, the other end of the screw rod 313 penetrates through the material cylinder bearing seat 32 at the rear end of the material cylinder 31 and is connected with a feeding driving device, so that the push disc device comprising the push disc and the screw rod pushes the extrusion piston 311 to move in the material cylinder 31 towards the direction of the material nozzle, and the glue solution in the material cylinder 31 is extruded from the material nozzle 35.

As shown in fig. 4e, the connection structure of the screw 313 and the push disc 312 and the relationship between the push disc and the extrusion piston 311 are specifically: the end part of the screw rod 313 is provided with a smaller diameter end, the smaller diameter end is provided with a clamping groove 313b, the screw rod 313 is sleeved with a flat pad 313c and penetrates through a central shaft hole of the push disc 312 with the concave middle part, an axial retaining ring 313d is clamped in the clamping groove 313b on the end part of the screw rod 313 extending out of the push disc 312, and the axial retaining ring 313d is sunk in the concave space of the push disc, so that the push disc 312 is fixed on the end part of the screw rod 313.

Such a piston structure is favorable for the separation of a charging barrel which is in contact with glue solution, an extrusion piston and a feeding driving device which is not in contact with the glue solution.

The extrusion piston 311 has a surface contact structure with the rear surface of the concave space and the push disc 312 inserted into the concave space, so that the circumferential surface contact structures of the two have the function of coaxial positioning. The screw rod is a long and thin structural part and has a swinging tendency, and the screw rod is more stable through the concave circumferential surface contact structure.

The outer diameter of the push disk 312 is preferably 8-11mm smaller than the outer diameter of the extrusion piston 311, for example, in one embodiment, the outer diameter of the push disk is 11mm smaller than the outer diameter of the extrusion piston.

To prevent the screw 313 from rotating, a rotation stopper 318 is provided on the inner surface of the cartridge bearing holder 32 to form a rotation stopper structure with the screw 313 for restricting the rotation of the screw 313. The rotation stopping structure is as follows: the screw 313 is provided with a through-long key groove 313e, and a protruding part on the rotation stop block 318 fixed on the bearing seat 32 of the charging barrel is embedded into the through-long key groove 313e, so that when the nut 313a is driven by the feeding motor 314 to rotate in place, the screw can only do linear motion relative to the rotation stop block 318 but cannot rotate, and moves in the charging barrel 31 to drive the push disc 312 to push the piston 311 to extrude the coating material in the charging barrel 31.

The charging barrel bearing seat 32 can adjust the height position of the rear end of the charging barrel 31 through a vertical long hole 111a on the adjusting plate 111 of the feeding mechanism, and the height position of the front end of the charging barrel 31 can be realized by adding a gasket between the charging barrel lower support plate 33 and the flat plate 11 of the bracket 1, so that the gap between the discharge hole of the charging nozzle 35 and the front roller 51 in the roller mechanism 5 is adjusted by adjusting the height position of the charging barrel 31 back and forth.

In the case of the example without the sub crawler, the rear roller 52 may roll the cloth material by rotating by a frictional force with the cloth. The added auxiliary crawler traveling mechanism is particularly combined with the front roller and the rear roller as described above, the two rollers are both driven by power, and the rolling effect on the cloth is better.

In the brushing process, in order to ensure the brushing quality, after each brushing of two gaps, the front and rear rollers are detached for cleaning, the adhesive solution attached to the rollers is washed off, the rolling quality is improved, the cloth feeding scroll is frequently detached and assembled, the cloth feeding scroll using the cloth materials is replaced, and a new cloth roll is replaced. This quick assembly disassembly structure can improve work efficiency greatly.

In addition, the special connecting structure of the charging barrel and the feeding driving device provides convenience for replacing the charging barrel with the used glue solution, replacing a new barrel filled with the glue solution and detaching a piston of the charging barrel for cleaning.

A specific example of the method for coating the airtight material between the plate seams of the wallboard of the controlled atmosphere preservation warehouse by using the coating machine is as follows:

step 1: the method comprises the following steps of filling a glue solution of airtight glue into a charging barrel 31 of a feeding mechanism, and installing the charging barrel on a charging barrel bearing seat 32 on a rack;

before the feeding cylinder 31 is filled with the airtight glue, the parts, contacting the airtight glue, of the extrusion piston 311, the material nozzle 35 and the like in the charging cylinder are coated with the vaseline paste, so that the extrusion piston can freely slide in the charging cylinder, the vaseline paste is coated, the extrusion piston is guaranteed to be lubricated and moved, and the parts are more convenient to clean.

Filling airtight glue into the charging barrel and installing a material nozzle in all normal states of the machine; the charging barrel 311 filled with airtight glue and the material nozzle 35 are arranged at the corresponding positions of the machine, and the long pull rod 36 is used for applying certain pressure to the material nozzle 35, so that the O-shaped sealing ring 35b at the material nozzle 35 is subjected to certain pressure to ensure sealing.

The front roller 51 and the rear roller 52, namely the sponge rollers 1# and 2# are correctly installed at the correct positions, and the rollers are checked to rotate flexibly and cannot be blocked.

Step 2: the cloth feeding scroll 41 of the cloth material coiled between two cloth shaft blocking pieces 45 on the cloth feeding scroll 41 is arranged on the frame 1, the end part of the cloth material passes through the space between the material nozzle 35 of the charging barrel 31 and the front roller 51, the cloth material is placed on the front roller 51, and the end of the cloth material naturally droops and grows out of one section of the bottom of the coating machine;

the non-woven fabric is rolled on the feeding cloth scroll 41, and the length of the non-woven fabric is reduced by 50-100mm according to the length of the plate seam; the cloth shaft is arranged at the correct position, and the rotation of the cloth shaft is checked to be flexible without clamping stagnation. The cloth pressing elastic sheet 47 is used for pressing the cloth roll and is not loosened.

The non-woven fabric is pulled out from the lower part of the material nozzle, bypasses the sponge roller of the front roller by 180 degrees, naturally hangs down along the machine and is slightly longer than the bottom of the machine by 20-40 mm.

And step 3: adjusting the position of the coating machine, placing the coating machine on a skirting board, aligning the center line of the cloth material with the board seam, and adsorbing the front end of a crawler-type travelling mechanism of the coating machine with the board wall of the color steel plate;

the bottom of the non-woven fabric is aligned with the board seam and the skirting, the painting machine is aligned with the board seam, and the painting machine is adsorbed on the color steel plate wallboard through the magnet.

And 4, step 4: starting a forward switch of a feeding driving device in the feeding mechanism, starting the forward switch of a motor of the travelling mechanism until rubber is extruded on the cloth, enabling the brushing machine to climb upwards along the board wall, continuously extruding the rubber to the cloth and being brought between the board wall and the board seam, bonding the cloth to the wall through rolling of a front roller 51 and a rear roller 52, simultaneously coating the rubber on the board wall and pressing the glue into the board seam by the cloth, adhering the cloth to the board wall, continuously travelling upwards by the brushing machine until the brushing machine reaches the top end of the wall, and finishing the treatment of the whole seam;

after a feeding switch on the feeding mechanism is started, a feeding motor 314, namely a synchronous belt driving wheel 315 on a speed regulating motor, namely a small synchronous belt wheel drives a synchronous belt driven wheel 316, namely a large synchronous belt wheel and nut 313a assembly to rotate through a synchronous belt, and a screw rod 313 linearly moves to push an extrusion piston 311 under the action of the large synchronous belt wheel and nut assembly and a rotation stopping block 318, so that airtight glue in a charging barrel 31 is extruded to non-woven fabrics on a No. 1 sponge roller from an outlet 35a of a nozzle 35. Starting a walking switch of the walking mechanism, and enabling the machine to climb upwards to bring the non-woven fabric with the airtight glue onto the wall board; after the airtight glue and the non-woven fabric are rolled by sponge rollers 1# and 2# to be stuck on the wallboard, the airtight glue is filled in the gaps of the wallboard wall.

When the airtight glue is used for the first time, the adjustable speed motor of the feeding mechanism is required to adjust the discharging speed to be matched with the crawling speed of the travelling mechanism, so that the extruded airtight glue is uniformly rolled on the wide surfaces of non-woven fabrics and the like.

When the travelling mechanism begins to climb, the non-woven fabric head needs to be pressed at the bottom of the machine first, so that the non-woven fabric can be prevented from being rolled in along with the No. 2 sponge roller when the travelling mechanism begins to work. When the airtight glue is rolled by the No. 2 sponge roller, the painting machine can be loosened to automatically travel after rising stably. And 5: when the brushing machine moves to the upper end of the plate wall, the forward switch of the feeding driving device of the feeding mechanism is closed, the reverse switch is opened, so that the extruding piston 311 in the charging barrel 31 returns, meanwhile, the forward switch of the motor in the traveling mechanism is closed, the reverse switch of the motor is opened, and the brushing machine travels downwards until the brushing machine is conveyed to the ground;

after the coating machine is placed on the ground, the charging barrel on the frame 1 is detached, namely, the charging barrel 31 and the extrusion piston 311 therein can be separated from the push disc 312 only by loosening the nut on the pull rod 36, and then the charging barrel and the extrusion piston are directly taken down, the standby charging barrel filled with glue solution is sleeved on the push disc, the nut on the pull rod is fixed, a new cloth feeding scroll is replaced, the coating machine is moved to be aligned with the next board seam, and the coating operation of the next seam is started.

When the machine works normally, ground personnel can directly fill the replaced charging barrel with airtight glue, or clean the residual glue solution in the charging barrel, and install a standby nozzle in place; winding the non-woven fabric on a standby fabric shaft until the non-woven fabric is wound tightly and compactly; charging the backup power source.

After the brushing machine returns to the ground again, the charging barrel and the cloth feeding scroll can be replaced again. If necessary, the front roller and the rear roller which are stuck with the glue solution can also be replaced and the battery can also be replaced.

The structure of the modified atmosphere storage panels 6 and the panel seams 65 is shown in fig. 7a and 7 d. The surface of the plate body of the storehouse plate is a color steel plate 61, and the core material is polyurethane 62. The width of the plate seam is 3-5mm, and the depth is 5-8 mm. In order to ensure that the coating machine fills the glue material in the straight line part of the plate seam (the turning part inside the seam can be free from filling the glue solution), the material nozzle 35 of the material cylinder 31 in the feeding mechanism is tested for a plurality of times to confirm the design shape.

In the feed mechanism 3, the opening of the nozzle 35 faces downward corresponding to the front roll 51, and the opening 35c of the nozzle 35 has a slit shape.

Preferably, the opening has a width of 3-8mm and a length of 80 mm. Correspondingly, the width of the cloth material is 100 mm. The slit of the opening 35b is wider in the middle and narrower on both sides. The middle wide portion corresponds to the slit. Specifically, the width of the middle of the strip seam is 5-8mm, and the width of the two sides of the strip seam is 3-5 mm. The length of the middle wider slot segment is 21-25 mm. More specifically, a grating is provided in the width direction on the slit of the opening, and two gratings divide the opening into three ports in the middle and two sides.

The grid can act as a reinforcement, providing strength and rigidity to the openings, and, in addition, by means of a nozzle designed in this way, it is also easier to press the glue into the plate seam.

When the diameter of the piston in the feeding mechanism is: 70mm, the linear motion mechanism that the pushing disc device connects is screw mechanism, wherein the pitch of lead screw: 3mm, the walking speed of the coating machine is as follows: 2.4-3 m/min; piston moving speed: 62-78 mm/min.

Considering the time required for the glue solution to enter the gap, if the traveling speed of the coating machine is too high or the pressing speed of the extrusion piston is slow, the gap is not filled, the adhesive edges on two sides of the non-woven fabric are not present, the non-woven fabric is not firmly adhered, and if the difference between the two parameters is too much, the glue solution is cut off; however, if the pressing speed of the extrusion piston is too high, glue liquid is wasted, in addition, the adhesive effect of the cloth on the plate wall is also affected because too much glue liquid flows out, and in the coating process, the glue liquid only needs to enter the plate wall gap 65 with the width of 3-5mm and the depth of about 3-5 mm. There is no need to enter into the curved slot. Too much glue can extrude from two sides of the cloth material, and the painting quality is influenced.

The glue is allowed to enter the slab joints through the mechanism of the material nozzle. In operation, the center of symmetry of the machine is opposite the slab seam. The cloth width is 100mm, the colloid width is 80mm, the slit width is 3-5mm, but is deeper, 5-8mm (see fig. 7d), therefore, in the embodiment shown in fig. 4k to 4n, the opening of the material nozzle is 80mm long, the middle is slightly wider, the width is 3-5mm in the length direction, and the middle is 5-8mm wide.

Selecting the sponge roller, wherein the diameter is 5-10mm larger than the overall height of the crawler belt, the diameter of the sponge with the width of 12-20mm in the middle is 2-5mm smaller than the diameter of the two sides, and the sponge roller is in smooth transition; the effects of thick middle and thin two sides of the coating can be ensured. Sponge hardness: 36-40 degrees.

Above-mentioned design, through to the structural design of material mouth export both sides narrow, middle width, combine the roll structure type selection, the coating result that obtains is: so that the coating is more extruded into the plate seam, the width of the sizing material is equivalent to that of the plate seam, and the extrusion depth is about 3-4 mm; the two sides of the coating are thin, the middle of the coating is thick, the thickness of the two sides is about 0.5-1mm, and the thickness of the middle is 1-2 mm. Such glue seam, when the wallboard had vibrations or little displacement, the tensile force received in the middle of the coating is the biggest, and the design of coating middle thickening for the coating is more reasonable.

Further, in step 4, when the coating machine starts to climb, the end part of the cloth needs to be pressed at the bottom of the machine, so that when the coating machine starts to work, the cloth is prevented from being rolled into a rear roller by the rotation of the rear roller, the pressed cloth can be loosened after the rear roller is rolled to adhere the cloth to a board wall, and the coating machine can automatically run. The brushing machine can be used for brushing the gap of the warehouse board once, but the brushing machine needs to be used for brushing twice manually.

Because of using permanent magnet, when taking place electrical apparatus trouble, the machine can be firm adsorbs on the wallboard, can not take place the accident that the outage loses magnetism and fall.

The cloth material passes through the space between the material nozzle and the front roller and is wound on the front roller by 180 degrees, and the initial section of cloth is free from glue and is a space occupied by the height of the machine, so that the board seam of the coating machine at the beginning end of the board seam, which is about 40-50cm in height and is occupied by the machine, needs to be manually repaired and brushed with airtight glue.

The glue is squeezed onto the cloth and the machine is moved upwards, the cloth being stationary relative to the machine. The machine continues upwards, applying the adhesive tape to the wall through the cloth, and the rollers spread and squeeze the adhesive across the cloth into the seams and densify.

At the position of a plate seam with a distance of about 5-10cm from the top of the warehouse, the airtight glue needs to be manually repaired and brushed due to the height limitation of the painting machine.

The length of the cloth wound on the feed roll 41 should be 5-10cm shorter than the length of a panel wall perps. When the coating machine reaches the ceiling, the No. 1 roller, namely the front roller, contacts the roof firstly. If the cloth is not shortened by 5-10cm, the cloth is at least 1/4 of the circumference of the roller on the roller, and the part cannot be adhered to the wall. When the coater moves back down, the cloth will be carried down with the reverse rotation of the roll. The cloth material is partially shortened, namely the front roller is pushed to the ceiling, and the cloth material is completely spread. The coating machine can not bring down the cloth belt when moving downwards, and the vertical seam part of the warehouse board, which is left near the ceiling, needs to be manually brushed and pasted with cloth.

During the working process, glue solution can be adhered to the front and rear rollers, the viscosity of the glue solution which is just extruded is smaller than the viscosity of the glue solution which is adhered to the surfaces of the rollers, if more glue solution remains on the rollers, the extruded glue solution can be easily adhered to the rollers, and the rolling effect of the rollers on cloth materials is influenced, so that after the brushing machine is adhered with a plurality of gaps, the standby rollers need to be replaced, the glue solution on the sponge rollers is washed off by the replaced rollers through clear water, and moisture is drained and reserved for standby. Therefore, the front roller and the rear roller can be frequently disassembled and assembled in use, the cloth feeding scroll needs to be disassembled and replaced with a standby scroll after the cloth is used up, and the quick disassembling and assembling structure of the front roller 51, the rear roller 52 and the cloth feeding scroll 41 can greatly improve the replacing speed and the working efficiency. The jack shaft structure provided by the utility model is very simple and reliable in use.

When the coating machine is used, the charging barrel, the nozzle and the extrusion piston need to be detached, and the residual materials in the charging barrel and the nozzle are returned to the airtight rubber barrel. Then clean with clean water, filter to remove water for standby.
