Description

Technical Field

[0001] The present invention relates to the technical field of spraying production devices, and in particular to a multi-media rotary feeding device and a use method thereof. Background Art

[0002] Spraying is a very common and important production process for fur surface treatment. The early spray gun running track was a straight reciprocating track. Because of its low production efficiency and easy color difference within the width, it is rarely used. Now the common running track on the market is circular or outer circle and inner square, but the improvement of leather spraying machine is mostly limited to the running track of the spray gun. In order to improve production efficiency, there are multiple spray guns running along the same track and implementing spraying operations, but only one slurry can be supplied, that is, no matter how many spray guns are used, they all spray the same color slurry. With the change and improvement of people's aesthetic concepts, people are increasingly in need of more varieties of colors, especially to cooperate with the development of some special patterns such as pyramid patterns, crocodile leather patterns, stone patterns, etc., the spray gun group needs to be able to spray two colors, reflecting the three-dimensional sense that is difficult to present in general surface treatment. The layers are very distinct, so there is an urgent need to improve the original equipment. Summary of the invention

The sealing mechanism is a commonly used technical means in this field and will not be repeated here.

[0007] An air intake cavity is provided inside the air intake head, and a plurality of sealing mechanisms are provided in the air intake cavity. The sealing mechanisms divide the air intake cavity between the feed shaft core and the air intake head into a main air intake cavity, an auxiliary air intake cavity 1 and an auxiliary air intake cavity 2. The main air intake cavity, the auxiliary air intake cavity 1 and the auxiliary air intake cavity 2 are respectively connected with the main air intake pipe, the auxiliary air intake pipe 1 and the auxiliary air intake pipe 2 on the corresponding feed shaft core through air intake holes; the main air intake cavity is connected with a main air intake connector Q, and the auxiliary air intake cavity 1 and the auxiliary air intake cavity 2 are respectively connected with an auxiliary air intake connector Q1 and an auxiliary air intake connector Q2, and the main air intake connector Q, the auxiliary air intake connector Q1 and the auxiliary air intake connector Q2 are all connected with an air storage tank; the auxiliary air intake connector Q1 and the auxiliary air intake connector Q2 are both single-inlet and single-outlet, and can be controlled by an electromagnetic valve to realize single opening and single stopping;

[0008] A feed cavity is provided inside the feed head A, and a feed connector A is connected to the feed cavity. The feed connector A is connected to the A storage tank through a pipeline three. A plurality of feed through holes are provided on the feed shaft core corresponding to the feed cavity, and the feed cavity is connected to the feed channel of the feed shaft core through the feed through holes. The A storage tank is filled with high-pressure slurry, and the slurry enters the pipeline three, the feed connector A, the feed cavity, the feed through holes, and the feed channel of the feed shaft core in sequence under the action of the A pneumatic slurry pump.

[0009] The feed head B comprises a feed shaft core, a feed inner tube, a feed head wire head and a feed chamber. The feed chamber comprises a feed body and a feed cover. A feed channel is arranged at the center of the feed shaft core. The feed body is rotatably sleeved on the bottom end of the feed shaft core through a bearing. The feed cover is fixed to the bottom end of the feed body through bolts. A feed connector B is arranged on the feed cover. The feed connector B is connected to the feed channel of the feed shaft core through a pipeline 1. The feed connector B is connected to the feed channel of the feed shaft core through a pipeline 2. The top of the feed shaft core extends to the outside of the feed body, the bottom of the feed inner tube is connected to the feed shaft core extending to the outside of the feed body through the feed head thread head, the feed inner tube is connected to the feed channel of the feed shaft core, the top of the feed inner tube extends into the feed channel of the feed shaft core and is connected to the discharge port b on the feed cavity, and the feed channel outside the feed inner tube is connected to the discharge port a on the feed cavity; the feed shaft core of the feed head B can rotate with the feed shaft core. High-pressure slurry is contained in the B storage tank, and enters pipeline 2, feed connector B, pipeline 1, the feed channel of the feed shaft core, and the feed inner tube in sequence under the action of the B pneumatic slurry pump.

[0010] Preferably, a support rod is fixed to the bottom end of the air supply cavity by bolts, a bracket is fixed on the support rod, and the solenoid valves on the second hose and the third hose are both fixed on the bracket. Because each solenoid valve is respectively connected to each hose 2 and hose 3 connected to the control air port, and thus controls the compressed air of the auxiliary air supply hole q1 and the auxiliary air supply hole q2 to enter the control air port of each spray gun, the support rod and the bracket can rotate with the spray gun with the rotation center of the spray gun as the center. The support rod is used to install the fixed supply and air supply pipelines, and the bracket is used to install each solenoid valve. In this way, under the action of the spray chamber transmission device, the spray gun rotates along the running track in the spray chamber, and at the same time drives the bracket, the support rod, the air supply and supply pipelines, the rotating shaft core, the supply cavity, the air supply cavity, the supply shaft core, and the feed shaft core of the feed head B to rotate with the rotation center as the center to form a rotating part, while the fixed sleeve is connected to the frame, the air intake head is connected to the external air supply device (such as an air storage tank), the feed head A is connected to the external supply device (such as A storage tank), and the feed head B is connected to the external supply device of the feed chamber (such as B storage tank) are all fixed and do not rotate to form a static part, and the solenoid valve controls the air intake of the control air port of the spray gun.

[0011] Preferably, an adjustment plate is fixed to the bottom end of the feed head B, and the adjustment plate is adjustably connected to the feed body by bolts. Pressure bearings are provided at the shoulders of the adjustment plate and the feed shaft core. The feed shaft core is pressed toward the feed cover through the pressure bearing by rotating the bolts. Since the feed shaft core rotates and the feed cover is fixed, there must be a gap f between the feed shaft core and the feed cover. If f is too small, the feed shaft core and the feed cover will rub against each other, and the rotation of the feed shaft core will be hindered. If f is too large, the slurry will easily leak out through f and invade the bearing. Therefore, the gap f between the feed shaft core and the feed cover is adjusted by adjusting the pressure plate to make the dynamic and static combination more reasonable, so as to ensure that the feed shaft core can rotate while the material entering the feed shaft core from the feed cover does not leak.

[0012] Preferably, the interconnections between the feed cavity, the air supply cavity, the air inlet head, the feed head A, the feed head B and the feed shaft core are all provided with sealing mechanisms to avoid leakage of material and air and ensure the normal use of the equipment.

[0013] A method for using a multi-media rotary feeding device comprises the following steps:

[0014] 1) Assign spray guns and solenoid valves: First, divide the spray guns and their corresponding solenoid valves into odd-group spray guns and even-group spray guns;

[0015] 2) Connect the feeding assembly: Secondly, connect the discharge port a and the discharge port b to the spray guns of the odd array and the spray guns of the even array respectively;

[0016] 3) Connect the air supply components: the air tank is connected to the main air inlet of each spray gun through the main air inlet connector Q, the main air inlet cavity, the main air inlet pipeline, the compressed air gathering tank, and the air supply hole q in sequence; the air tank is connected to the control air inlet of the spray gun connected to the discharge port a through the auxiliary air inlet connector Q1, the auxiliary air inlet cavity 1, the auxiliary air inlet pipeline 1, and the auxiliary air supply hole q1 in sequence; the air tank is connected to the control air inlet of the spray gun connected to the discharge port b through the auxiliary air inlet connector Q2, the auxiliary air inlet cavity 2, the auxiliary air inlet pipeline 2, and the auxiliary air supply hole q2 in sequence;

[0017] 4) Connect the slurry: Under the action of pneumatic slurry pump A, the slurry in storage tank A enters into feed joint A, feed cavity, feed channel, discharge port a, and spray guns of odd array in sequence, and then is sprayed out; under the action of pneumatic slurry pump B, the slurry in storage tank B enters into feed joint B, feed shaft core, feed inner tube, discharge port b, and spray guns of even array in sequence, and then is sprayed out.

[0018] The present invention also includes other components that enable a multi-media rotary feeding device to be used normally, such as a spray chamber transmission device, a slide rod device for mounting a spray gun, a frame, a control component of a gas storage tank, a control component of a spray gun, a fixing component of a spray gun, a control component for controlling the rotation of a rotating shaft core, a control component for controlling the movement of each spray gun on a running track, and a control component for a solenoid valve, all of which are conventional technical means in the art.

[0019] The working principle of the present invention is that under the action of the spray chamber transmission device, the spray gun rotates along the running track in the spray chamber, and at the same time drives the bracket, the support rod, the air supply and material supply pipelines, the rotating shaft core, the material supply chamber, the air supply chamber, the material supply shaft core, and the material supply shaft core of the feed head B to rotate around the rotation center to form a rotating part, while the fixed sleeve is connected to the frame, the air intake head is connected to the external air supply device (such as an air storage tank), the feed head A is connected to the external material supply device (such as A storage tank), and the feed head B is connected to the external material supply device of the feed chamber (such as B storage tank) are all fixed and do not rotate to form a static part; the compressed air from the air storage tank is divided into three groups, and enters the main air intake pipe, auxiliary air intake pipe one, auxiliary air intake pipe two on the material supply shaft core through the main air intake joint Q, the auxiliary air intake joint Q1, and the auxiliary air intake joint Q2, and the main air intake pipe The channel supplies air to the main air port of each spray gun through the air supply hole q, so as to control the spray gun to spray the slurry. The auxiliary air inlet pipeline 1 and the auxiliary air supply hole q1 are connected to the control air port of the spray gun connected to the discharge port a, and the auxiliary air inlet pipeline 2 and the auxiliary air supply hole q2 are connected to the control air port of the spray gun connected to the discharge port b. Through the control of the solenoid valve, when compressed air is introduced into the control air port, the air valve of the spray gun can be opened, and then the compressed air of the main air port directly sprays the slurry. The compressed air of the main air port is always connected, which reduces delays and errors, improves the efficiency of spraying, and ensures the timeliness of the spraying action. When spraying is not required, under the control of the solenoid valve, the control air port is no longer introduced with compressed air, the air valve of the spray gun is closed, and the spray gun no longer sprays the slurry (the structure and connection method of the control air port and the main air port are prior art and will not be repeated here);

[0020] The slurry in the A storage tank is sprayed through the feed joint A, the feed cavity, the feed channel, the discharge port a and the gun connected to the discharge port a in sequence under the action of the A pneumatic slurry pump, and is sprayed after being sprayed out; the slurry in the B storage tank is sprayed through the feed joint B, the feed shaft core, the feed inner tube, the discharge port b and the gun connected to the discharge port b in sequence under the action of the B pneumatic slurry pump, and is sprayed after being sprayed out.

[0021] The beneficial effects of the present invention are simple and reasonable structure, easy to use, and can rotate with the spray gun about its rotation center, and can meet the needs of different spray guns to spray different color slurries; the various components are connected and coordinated with each other, and the air supply, material supply, spray gun and storage tank cooperate with each other to achieve high-quality and high-efficiency spraying effects, the feed shaft core cooperates with the feed shaft core, and then cooperates with the feed cavity, feed head A, and feed head B, so that the two slurries do not interfere with each other, and the spraying can be completed smoothly and efficiently, improving the spraying quality and spraying effect, meeting people's needs for different colors, and improving the benefits of manufacturers.

The sealing mechanism is a commonly used technical means in this field and will not be repeated here.

[0041] An air intake cavity is provided inside the air intake head 6, and a plurality of sealing mechanisms 25 are provided in the air intake cavity. The sealing mechanism 25 divides the air intake cavity between the feed shaft core 35 and the air intake head 6 into a main air intake cavity 30, an auxiliary air intake cavity 1 29 and an auxiliary air intake cavity 2 28.

A plurality of feed through holes 33 are provided on the feed shaft core 35 corresponding to the feed cavity 38, and the feed cavity 38 is connected to the feed channel 32 of the feed shaft core 35 through the feed through holes 33;

[0043] The feed head B8 comprises a feed shaft core 21, a feed inner tube 19, a feed head wire head 20 and a feed chamber, wherein the feed chamber comprises a feed body 22 and a feed cover 23, a feed channel is arranged at the center of the feed shaft core 21, the feed body 22 is rotatably sleeved on the bottom end of the feed shaft core 21 through a bearing, the feed cover 23 is fixed to the bottom end of the feed body 22 through bolts, a feed connector B9 is arranged on the feed cover 23, and the feed connector B9 is connected to the feed channel of the feed shaft core 21 through a pipeline ... 9 is connected with the B storage tank through pipeline 2, the top end of the feed shaft core 21 extends to the outside of the feed body 22, the bottom end of the feed inner tube 19 is connected with the feed shaft core 21 extending to the outside of the feed body 22 through the feed head wire head 20, the feed inner tube 19 is connected with the feed channel of the feed shaft core 21, the top end of the feed inner tube 19 extends into the feed channel 32 of the feed shaft core 35 and is connected with the discharge port b17 on the feed cavity 2, the feed channel 32 outside the feed inner tube 19 is connected with the discharge port a18 on the feed cavity 2; the feed shaft core 21 of the feed head B8 can rotate together with the feed shaft core 35.

[0044] A support rod 5 is fixed to the top of the air supply chamber 3 by bolts, and a bracket 4 is fixed on the support rod 5. The solenoid valves on the hose 2 and hose 3 are fixed on the bracket 4.

Therefore, the gap f between the feed shaft core and the feed cover is adjusted by adjusting the pressure plate to make the combination of movement and static more reasonable, so as to ensure that the feed shaft core can rotate while the material entering the feed shaft core from the feed cover does not leak.

[0046] The interconnections between the feed cavity 2, the air supply cavity 3, the air inlet head 6, the feed head A7, the feed head B8 and the feed shaft core 35 are all provided with sealing mechanisms to avoid leakage of materials and air, thereby ensuring the normal use of the equipment.

[0047] A method for using a multi-media rotary feeding device comprises the following steps:

[0048] 1) Assign spray guns and solenoid valves: First, divide the spray guns and their corresponding solenoid valves into odd-group spray guns and even-group spray guns;

[0049] 2) Connect the feeding components: Secondly, connect the discharge port a and the discharge port b to the spray guns of the odd array and the spray guns of the even array respectively;

[0050] 3) The air storage tank is connected to the main air ports of each spray gun through the main air inlet joint Q, the main air inlet cavity, the main air inlet pipeline, the compressed air gathering tank, and the air supply hole q in sequence; the air storage tank is connected to the control air port of the spray gun connected to the discharge port a through the auxiliary air inlet joint Q1, the auxiliary air inlet cavity 1, the auxiliary air inlet pipeline 1, and the auxiliary air supply hole q1 in sequence; the air storage tank is connected to the control air port of the spray gun connected to the discharge port b through the auxiliary air inlet joint Q2, the auxiliary air inlet cavity 2, the auxiliary air inlet pipeline 2, and the auxiliary air supply hole q2 in sequence;

[0051] 4) Connect the slurry: Under the action of pneumatic slurry pump A, the slurry in storage tank A is sprayed out through feed joint A, feed cavity, feed channel, discharge port a, and odd-numbered spray guns in turn for spraying; under the action of pneumatic slurry pump B, the slurry in storage tank B is sprayed out through feed joint B, feed shaft core, feed inner tube, discharge port b, and even-numbered spray guns in turn for spraying.

[0052] When in use, taking the outer circle inner square track 40 as an example, eight spray guns Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ, and Ⅷ are set, the odd-numbered spray guns are connected to the A slurry, and the even-numbered spray guns are connected to the B slurry. When the eight spray guns are running on the track, the spray guns moving to the arc segments CF and DE do not perform spraying action, and the spray guns moving to the straight segments CD and EF perform spraying action under the action of the control system (the control system is a prior art and will not be repeated here), as follows:

[0053] First, there are three groups of selections on the control system: odd, even or odd-even. When "odd" is selected, spray guns Ⅰ, Ⅲ, Ⅴ, and Ⅶ are in standby state, and they and the four even-numbered spray guns are in shutdown state. At this time, it is single-color spraying; when "even" is selected, spray guns Ⅱ, Ⅳ, Ⅵ, and Ⅷ are in standby state, and they and the four odd-numbered spray guns are in shutdown state. At this time, it is also single-color spraying; when "odd-even" is selected, all eight spray guns are in standby state. At this time, if the odd-numbered spray gun and the even-numbered spray gun are connected to the same color slurry, it is also single-color spraying, but the spraying efficiency is twice that of "odd" and "even" spraying, which improves the efficiency of single-color spraying. If the odd-numbered spray gun and the even-numbered spray gun are connected to different colors of slurries, it is two-color spraying.

[0054] Finally, when each spray gun rotates clockwise on the outer circle inner square track 40, when the spray gun runs to point E or C, the spray gun in standby state is sensed by the position switch at E or C (here is the prior art), and after the position of the spray gun is confirmed, the solenoid valve corresponding to the spray gun is energized, the air path of the control air port is connected, compressed air is introduced into the spray gun control air port, the slurry outlet of the spray gun is opened, and the slurry is pushed and sprayed out under the pressure of the compressed air introduced into the main air port, and the spraying operation begins; when it runs to F or D, after being sensed by the position switch, the solenoid valve loses power, the air path of the control air port is closed, the slurry outlet of the spray gun is closed, and the spraying operation is stopped, and this cycle is repeated to make the spraying operation orderly.

[0055] By adjusting the slurry and the coordination of the spray guns according to the above method, the multi-media rotary feeding device can be used to produce yin and yang colors for patterns with strong three-dimensional sense such as "crocodile skin pattern" and "pyramid pattern", that is, yin and yang double-sided double-color, which is difficult to achieve with general devices.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of the present invention.
