Description

Technical Field

[0001] The utility model belongs to the technical field of bottle cap processing equipment, and particularly relates to a bottle cap quick-disassembly spraying conveying mechanism. Background Art

[0002] Bottle caps are used extensively in beverages, condiments, and alcoholic beverages. To adapt to the appearance of different products, they need to be sprayed in different colors. Today, spraying bottle caps has developed into an assembly line, compensating for the lack of production capacity of manual bottle cap transfer in the past.

[0003] The spraying line features a conveyor belt for continuously transporting bottle caps. To maintain a stable vertical position, the conveyor belt features a number of hollow rods fixed along its centerline. The upper ends of these rods are inserted into the bottle caps to support them. Several steel balls are also rotatably mounted on the upper ends of the rods to mitigate friction between the rods and the caps.

[0004] When the conveyor belt transports bottle caps, a spring is used to push the piston inside the hollow rod to tighten the steel balls, and the middle of the hollow rod can be disassembled along the thread. Especially when spraying, the atomized paint enters the hollow rod along the gap between the steel balls and adheres to the thread, causing the thread to be blocked, which hinders the disassembly process of the hollow rod. For this reason, we propose a bottle cap quick-disassembly spraying conveying mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a bottle cap quick-detachable spraying conveying mechanism, which can quickly remove the hollow round rod from the conveyor belt, and the disassembly position is far away from the paint spray gun, which is convenient for reducing the obstruction caused by the atomized paint.

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

[0007] A conveying mechanism for quick-detachable spraying of bottle caps, comprising a conveyor belt, wherein a plurality of groups of baffles are fixed at intervals on the outer surface of the conveyor belt, wherein the two baffles in each group are parallel to each other and two parallel folding plates are inserted between the two baffles in each group, wherein one end of the folding plate extends horizontally between the two baffles and the other end of the folding plate is bent obliquely upward, a hollow round rod is fixed between the upper ends of two adjacent folding plates, and the hollow round rod is perpendicular to the conveyor belt, and a plurality of square belts are arranged above the two baffles in each group, wherein the two ends of the square belts extend to the outside of the two adjacent baffles respectively. Before spraying the bottle caps, the hollow round rod is centered on the conveyor belt and fixed with several four-corner belts around the folding plate; when spraying the bottle caps, the conveyor belt moves forward intermittently under the drive of the servo motor, and the bottle caps are placed one by one by the robot, with the bottle cap opening facing down and put on the upper end of the hollow round rod. The spring is used to tighten the card sleeve to push each steel ball against the inner wall of the bottle cap, and the bottle caps are sent to the bottom of the paint spray gun one by one; after the transportation is completed, the line is stopped for maintenance, the four-corner belts can be unplugged and disassembled, the two folding plates and the hollow round rod can be loosened, and the hollow round rod can be quickly removed from the conveyor belt. The disassembly position is far away from the paint spray gun, which is convenient for reducing the obstruction of the atomized paint.

[0008] A number of positioning grooves are spaced apart at one horizontal end of the folding plate, and the positioning grooves are horizontally staggered with adjacent baffles. The positioning grooves are penetrated by adjacent four-corner belts. The baffles horizontally support the positioning grooves, which play a positioning role for the folding plate, can straighten the folding plate and the hollow round rod, and reduce the degree of deviation of the hollow round rod on the conveyor belt.

[0009] A group of metal snaps are installed at both ends of the four-corner straps, and each group of metal snaps includes a male snap and a female snap, wherein the female snaps are fixed to the four-corner straps, and the male snaps are fixed to the adjacent baffles. By moving the four-corner straps by hand and engaging the male and female snaps with each other, the two ends of the four-corner straps can be fixed to the outside of the two baffles respectively. Conversely, by pulling apart the male and female snaps, the four-corner straps can be disassembled, and the locking effect of the folding plate can be released, so that the folding plate can be quickly removed by pulling.

[0010] An inserting plate is fixed in the middle of the lower surface of the four-corner belt, and the inserting plates pass through the positioning grooves of two adjacent folding plates. The inserting plates are used to enhance the rigidity of the four-corner belt, especially when inserted tightly between two adjacent positioning grooves, so that the two folding plates can be straightened and aligned, so that the positioning grooves and the four-corner belts are consistent, and the degree of misalignment is reduced.

[0011] An elastic pad is fixed to one end of the hollow rod away from the conveyor belt. When the bottle cap falls, it is supported by the elastic pad on the hollow rod. The deformation of the elastic pad itself can buffer the bottle cap and avoid hard collision.

[0012] A nylon layer is fixed to the upper edges of the two baffles in each group that are away from each other. The width of the nylon layer is not greater than the width of the male buckle. The nylon layer can cover the upper edge of the baffle, separate the upper edge from the four corner belts, and prevent the upper edge from cutting the four corners.

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

[0014] The utility model discloses a conveying mechanism for quick-detachable spraying of bottle caps. Before spraying the bottle caps, the hollow round rod is centered on the conveyor belt and then fixed by passing a plurality of four-corner belts around a folding plate. When spraying the bottle caps, the conveyor belt is driven by a servo motor to intermittently advance, and the bottle caps are placed one by one by a robot arm. The bottle caps are sleeved on the upper end of the hollow round rod with the opening facing downward, and the clamping sleeve is tightened by a spring to push each steel ball against the inner wall of the bottle cap, so that the bottle caps are sent to the bottom of the paint spray gun one by one. After conveying is completed, the line is stopped for maintenance, the four-corner belts can be pulled out and disassembled, the two folding plates and the hollow round rod can be loosened, and the hollow round rod can be quickly disassembled from the conveyor belt. The disassembly position is far away from the paint spray gun, which is convenient for reducing the obstruction of the atomized paint. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0022] like Figure 1-4As shown, a bottle cap quick-detachable spraying conveying mechanism includes a conveyor belt 1. The rotating shaft of the conveyor belt 1 can be installed on the spraying assembly line and driven by a servo motor. Several groups of baffles 2 are fixed at intervals on the outer surface of the conveyor belt 1. The two baffles 2 in each group are parallel to each other and two parallel folding plates 3 are inserted between the two baffles 2 in each group. One end of the folding plate 3 extends horizontally between the two baffles 2, and the other end of the folding plate 3 is bent obliquely upward. A hollow round rod 4 is fixed between the upper ends of two adjacent folding plates 3. The Chinese utility model with reference to publication number CN215843721U is a bottle cap quick-detachable spraying conveying device. Several steel balls are embedded and installed on the outside of the hollow round rod 4. A spring and a clamping sleeve are provided inside the hollow round rod 4. , the hollow round rod 4 is a two-section split structure and the split is also threaded with screws. The hollow round rods 4 are perpendicular to the belt of the conveyor belt 1. A number of square belts 5 are provided above each group of two baffles 2. The square belts 5 can be made of the same material as the tractor V-belt. The cross-section of the square belts 5 is inverted trapezoidal, and the two ends of the square belts 5 extend to the outside of the two adjacent baffles 2. Before spraying the bottle caps, the hollow round rod 4 and the two adjacent folding plates 3 are fixed together, and the two adjacent folding plates 3 are horizontally inserted into the interval between the two adjacent baffles 2. After the hollow round rod 4 is centered on the conveyor belt 1, a number of square belts 5 are used to bypass one horizontal end of the folding plate 3 and are detachably connected to the outside of the two adjacent baffles 2 to tighten the folding plate 3 to complete the fixation of the hollow round rod 4;

[0023] When spraying bottle caps, the conveyor belt 1 moves forward intermittently under the drive of the servo motor, and the bottle caps are placed one by one by the robot. The bottle cap opening is placed on the upper end of the hollow round rod 4 with the cap opening facing downward. The spring is used to tighten the clamping sleeve to push each steel ball against the inner wall of the bottle cap, and the bottle caps are sent to the bottom of the paint spray gun one by one. Some mist paint may enter the interior of the hollow round rod 4.

[0024] After the conveying is completed, the line is stopped for maintenance. The four-corner belt 5 can be unplugged and disassembled, and the two folding plates 3 and the hollow round rod 4 can be loosened. The hollow round rod 4 can be quickly removed from the conveyor belt 1. The disassembly position is far away from the paint spray gun, and there is very little adhesion of mist paint, which is convenient for reducing the obstruction of the atomized paint. After removal, the screws can be unscrewed with a screwdriver, and the hollow round rod 4 can be disassembled into two sections to expose the spring, steel ball and ferrule; since the screws are far away from the paint spray gun, they rarely come into contact with mist paint. Even if the screws are stained with paint, they can be scraped off with a screwdriver, which is convenient for disassembly.

[0025] Since there is a gap between the two baffles 2 and a gap between the two folding plates 3, the curved position of the conveyor belt 1 can be deformed at these two gaps, which is beneficial to improving the smoothness of the operation of the conveying mechanism.

[0026] like Figure 1 、 Figure 3 and Figure 4As shown, a number of positioning grooves 6 are spaced apart at one horizontal end of the folding plate 3, and the positioning grooves 6 are horizontally staggered with adjacent baffles 2. The positioning grooves 6 are penetrated by adjacent four-corner belts 5. The baffles 2 horizontally support the positioning grooves 6, which play a positioning role on the folding plate 3, and cooperate with the baffles 2 to lock the folding plate 3, which can straighten the folding plate 3 and the hollow round rod 4, and reduce the degree of offset of the hollow round rod 4 on the conveyor belt 1.

[0027] like Figure 2 and Figure 4 As shown, a group of metal snaps 7 are installed at both ends of the four-corner strap 5, and each group of metal snaps 7 includes a male snap and a female snap, wherein the female snaps are fixed to the four-corner strap 5, and the male snaps are fixed to the adjacent baffles 2. By moving the four-corner strap 5 by hand and engaging the male and female snaps with each other, the two ends of the four-corner strap 5 can be fixed to the outside of the two baffles 2 respectively. Conversely, by pulling apart the male and female snaps, the four-corner strap 5 can be disassembled, and the locking effect of the folding plate 3 can be released, so that the folding plate 3 can be quickly removed by pulling.

[0028] like Figure 3 and Figure 4 As shown, an insert plate 8 is fixed in the middle of the lower surface of the four-corner band 5, and the insert plates 8 pass through the positioning grooves 6 of two adjacent folding plates 3. The insert plates 8 are used to enhance the rigidity of the four-corner band 5, especially when inserted tightly between two adjacent positioning grooves 6, so that the two folding plates 3 can be straightened and aligned, so that the positioning grooves 6 are consistent with the four-corner band 5, and the degree of misalignment is reduced.

[0029] like Figure 1 and Figure 3 As shown, an elastic pad 9 is fixed to the end of the hollow rod 4 away from the conveyor belt 1. The elastic pad 9 can be made of food-grade silicone. When the bottle cap falls, the elastic pad 9 on the hollow rod 4 is used to support it. The deformation of the elastic pad 9 itself can buffer the bottle cap and avoid hard collision.

[0030] like Figure 1 、 Figure 2 and Figure 4 As shown, a nylon layer 10 is fixed to the upper edges of each group of two baffles 2 that are away from each other. The width of the nylon layer 10 is not greater than the width of the male buckle. The nylon layer 10 can cover the upper edge of the baffle 2, separating the upper edge from the four-corner belt 5, and preventing the upper edge from cutting the four-corner belt 5.

[0031] The working principle of the utility model is as follows: before spraying the bottle cap, the hollow round rod 4 and the two adjacent folding plates 3 are fixed together, and the two adjacent folding plates 3 are horizontally inserted into the gap between the two adjacent baffles 2. After the hollow round rod 4 is centered on the conveyor belt 1, a plurality of square belts 5 are used to pass around the horizontal end of the folding plate 3 and detachably connect to the outer sides of the two adjacent baffles 2 to tighten the folding plate 3 and complete the fixation of the hollow round rod 4;

[0032] When spraying bottle caps, the conveyor belt 1 moves forward intermittently under the drive of the servo motor, and the bottle caps are placed one by one by the robot. The bottle cap opening is placed on the upper end of the hollow round rod 4 with the cap opening facing downward. The spring is used to tighten the clamping sleeve to push each steel ball against the inner wall of the bottle cap, and the bottle caps are sent to the bottom of the paint spray gun one by one. Some mist paint may enter the interior of the hollow round rod 4.

[0033] After the conveying is completed, the line is stopped for maintenance. The four-corner belt 5 can be unplugged and disassembled, and the two folding plates 3 and the hollow round rod 4 can be loosened. The hollow round rod 4 can be quickly removed from the conveyor belt 1. The disassembly position is far away from the paint spray gun, which is convenient for reducing the obstruction of the atomized paint. After removal, the screws can be unscrewed with a screwdriver, and the hollow round rod 4 can be disassembled into two sections to expose the spring, steel ball and ferrule; since the screws are far away from the paint spray gun, they rarely come into contact with the mist paint. Even if the screws are stained with paint, they can be scraped off with a screwdriver for easy disassembly.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
