Description

Technical Field

[0001] The utility model belongs to the technical field of bottle cap spraying equipment, and specifically relates to a high-density functional bottle cap surface spraying device. Background Art

[0002] High-density functional bottle caps are generally made of polyethylene as the base material, and are molded by adding a variety of ingredients. The molded blanks have a single surface color and need to be placed on the spraying line. The spraying paint has a more beautiful effect. The sides and upper surfaces of the bottle caps must be sprayed, and the spray paint must be even.

[0003] After the bottle caps are sent to the spraying line, they need to be sprayed circumferentially. Multiple spray nozzles are fixed in the cap barrel and lowered by the lifting cylinder to surround the bottle caps from the outside. When the bottle caps are sprayed, they are driven by an electric rotating mechanism and rotate continuously to evenly distribute the paint.

[0004] After the bottle caps arrive at the spraying station, lifting the cap barrel with multiple spray nozzles will take up the time for loading and unloading the bottle caps. Instead, using several fixed spray guns, even if the bottle caps are surrounded, the bottle caps still need to be rotated at the spraying station, so that the bottle caps are taken and placed from the electric rotating mechanism, which takes up the spraying time and is not conducive to shortening the bottle cap spraying interval. For this reason, we propose a high-density functional bottle cap surface spraying device. Utility Model Content

[0005] The purpose of the utility model is to provide a high-density functional bottle cap surface spraying device, which does not need to rotate the bottle cap at the spraying station, and the bottle cap can be smoothly loaded or unloaded after the spraying is completed, so as to shorten the bottle cap spraying interval.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A high-density functional bottle cap surface spraying device, comprising a pigment pumping tube, a hard tube is axially rotatably installed at the lower end of the pigment pumping tube, a transmission mechanism is arranged on the outside of the hard tube, a right-angle elbow is vertically fixed to the end of the hard tube away from the pigment pumping tube, the right-angle elbow is bent at 90 degrees, one end of the right-angle elbow away from the hard tube is closed, two straight sides of the right-angle elbow are respectively connected and fixed with a plurality of nozzles, and also comprises a brake motor fixedly connected to the transmission mechanism. When processing bottle caps, the bottle caps are sent to the spraying station one by one by using a conveyor belt, and the vertical side of the right-angle elbow is in the initial position The conveying direction of the bottle caps is staggered horizontally, and the brake motor is started intermittently. The transmission mechanism rotates the hard tube forward, driving the right-angle elbow to surround the bottle caps at an angle of 360°, and the material pump is started synchronously. Paint is conveyed to several nozzles along the paint pumping tube, hard tube and right-angle elbow, so that the nozzles spray paint on the bottle caps while rotating. The spraying stops when the rotation stops. There is no need to rotate the bottle caps at the spraying station. After the bottle caps are sprayed, they can be smoothly loaded or unloaded without obvious jamming. The brake motor reverses the hard tube for the next bottle cap to drive the nozzle to complete the spraying. This is repeated to spray the subsequent bottle caps in order to shorten the spraying interval of the bottle caps.

[0008] A bottle cap in place sensor is fixed on the outside of the hard tube at a position below the transmission mechanism. The bottle cap in place sensor is vertically staggered with the right-angle bend tube. After the bottle cap reaches the spraying station, it causes the bottle cap in place sensor signal to change. If the signal change lasts for at least a certain time, it means that the bottle cap is under the hard tube. The bottle cap in place situation can be quickly identified, and guidance can be provided for starting or stopping the brake motor.

[0009] The transmission mechanism includes a gear ring fixedly arranged on the outside of the hard tube, the outside of the gear ring is a tooth structure and these teeth are meshed and connected with a driving gear, the middle of the driving gear is axially fixedly connected to the output end of the brake motor, after the brake motor is started, the driving gear is driven to rotate, and the driving gear drives the gear ring and the hard tube to rotate forward or reverse, and the brake motor is fixed on the spraying assembly line.

[0010] An upper flange is fixed to the upper end of the brake motor, and pin holes are provided at the corners of the upper flange. After being fixed to the spraying assembly line by bolts, the brake motor can be stably suspended to reduce unnecessary jitter when the brake motor is loaded.

[0011] A quick plug is fixed axially on the upper end of the pigment pumping pipe. The quick plug is plugged into the discharge pipe of the pigment tank to enable quick connection. Conversely, the quick plug is pulled out to facilitate quick replacement of the pigment tank.

[0012] The paint pumping tube is provided with a restraining band on the outside, and both ends of the restraining band are detachably connected to the outside of the upper flange. The restraining band can be made of alloy material and can be fixed to the outside of the upper flange with screws. It can be close to the outside of the paint pumping tube and locked by friction to remove the reaction when the nozzle sprays paint.

[0013] The technical effects achieved by this utility model are:

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a high-density functional bottle cap surface spraying device includes a pigment pumping tube 1, the upper end of the pigment pumping tube 1 is connected to a pigment tank with a material pump, this technical solution is a prior art, not shown in the figure, the lower end of the pigment pumping tube 1 is axially rotatably mounted with a hard tube 2, a transmission mechanism is arranged on the outside of the hard tube 2, a right-angle bend 3 is vertically fixed to the end of the hard tube 2 away from the pigment pumping tube 1, the right-angle bend 3 is bent at 90°, one end of the right-angle bend 3 away from the hard tube 2 is closed, two straight sides of the right-angle bend 3 are connected and fixed with a plurality of nozzles 4, and also includes a brake motor 5 fixedly connected to the transmission mechanism, the signal of the brake motor 5 is connected to the industrial computer of the spraying assembly line, the brake motor 5 can select a 220V Y90-90 model three-phase electric micro motor, when processing high-sealing functional bottle caps , use a conveyor belt to send these bottle caps to the spraying line one by one. When the bottle cap arrives at the spraying station, the central axis of the bottle cap coincides with the central axis of the hard tube 2, and the initial position of the vertical side of the right-angle bend tube 3 is horizontally staggered from the conveying direction of the bottle cap. The brake motor 5 is started intermittently, and the transmission mechanism is coordinated to rotate the hard tube 2 forward, driving the right-angle bend tube 3 to surround the bottle cap at an angle of 360°, and the material pump is started synchronously, and the pigment is conveyed to a plurality of nozzles 4 along the pigment pumping pipe 1, the hard tube 2 and the right-angle bend tube 3, so that the nozzle 4 sprays paint on the bottle cap while rotating, and stops spraying. There is no need to rotate the bottle cap at the spraying station. After the bottle cap is sprayed, it can be smoothly loaded or unloaded without obvious jamming. The brake motor 5 reverses the hard tube 2 for the next bottle cap, driving the nozzle 4 to complete the spraying. This is repeated to spray the subsequent bottle caps so as to shorten the bottle cap spraying interval.

[0023] Among them, a nozzle 4 close to the central axis of the hard tube 2 is close to the middle of the bottle cap. Since the central axis of the bottle cap coincides with the central axis of the hard tube 2, the spraying range of this nozzle 4 is close to the middle of the bottle cap. When the hard tube 2 rotates, the spraying range will not overlap and no blank spraying area will be generated, thereby avoiding spraying leakage.

[0024] like Figure 1 and Figure 2 As shown, a bottle cap in place sensor 6 is fixed at a position below the transmission mechanism on the outside of the hard tube 2. The bottle cap in place sensor 6 can use a FTM-50B laser displacement sensor. The signal of the bottle cap in place sensor 6 is connected to the industrial computer of the spraying line. The bottle cap in place sensor 6 is vertically staggered from the right-angle bend pipe 3. After the bottle cap arrives at the spraying station, the signal of the bottle cap in place sensor 6 changes. If the signal change lasts for at least a certain time, it means that the bottle cap is below the hard tube 2. The bottle cap in place situation can be quickly identified, and guidance is provided for starting or stopping the brake motor 5.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the transmission mechanism includes a gear ring 7 fixedly arranged on the outside of the hard tube 2, the outside of the gear ring 7 is a tooth structure and these teeth are meshed and connected with a driving gear 8, the middle of the driving gear 8 is axially fixedly connected to the output end of the brake motor 5, after the brake motor 5 is started, the driving gear 8 is driven to rotate, and the driving gear 8 drives the gear ring 7 and the hard tube 2 to rotate forward or reverse, and the brake motor 5 is fixed on the spraying assembly line.

[0026] like Figure 1 and Figure 4 As shown, an upper flange 9 is fixed to the upper end of the brake motor 5, and pin holes are provided at the corners of the upper flange 9. After being fixed to the spraying assembly line by bolts, the brake motor 5 can be stably suspended to reduce unnecessary jitter of the brake motor 5 when it is loaded.

[0027] like Figure 1 As shown, a quick plug 10 is fixed axially to the upper end of the pigment pumping tube 1. The quick plug 10 is plugged into the discharge pipe of the pigment tank for quick connection. Conversely, the quick plug 10 is pulled out to facilitate quick replacement of the pigment tank.

[0028] like Figure 1 and Figure 4 As shown, a restraining band 11 is provided on the outside of the paint pumping tube 1, and both ends of the restraining band 11 are detachably connected to the outside of the upper flange 9. The restraining band 11 can be made of alloy material. After being fixed to the outside of the upper flange 9 by screws, it can be close to the outside of the paint pumping tube 1 and locked by friction, so as to remove the reaction of the nozzle 4 when spraying paint.

[0029] The working principle of the utility model is as follows: when processing bottle caps with high sealing functionality, the bottle caps are sent to the spraying line one by one by means of a conveyor belt. When the bottle caps arrive at the spraying station, the central axis of the bottle caps coincides with the central axis of the hard tube 2, and the vertical side of the right-angle bend tube 3 is initially positioned horizontally away from the conveying direction of the bottle caps. The brake motor 5 is started intermittently, and the transmission mechanism is coordinated to rotate the hard tube 2 forward, driving the right-angle bend tube 3 to surround the bottle caps at an angle of 360°, and the material pump is started synchronously, and paint is conveyed to a plurality of nozzles 4 along the paint pumping pipe 1, the hard tube 2 and the right-angle bend tube 3, so that the nozzles 4 rotate while spraying paint toward the bottle caps, and the spraying stops when the rotation stops. There is no need to rotate the bottle caps at the spraying station. After the bottle caps are sprayed, they can be smoothly loaded or unloaded without obvious jamming. The brake motor 5 reverses the hard tube 2 for the next bottle cap, driving the nozzle 4 to complete the spraying, and this is repeated to spray the subsequent bottle caps so as to shorten the bottle cap spraying interval.
