Description

Technical Field

[0001] This utility model relates to the field of bottle cap printing technology, specifically to a guide feeding unit for bottle cap printing. Background Technology

[0002] With the rapid development of the food, beverage, and daily chemical industries, the demand for bottle caps is constantly increasing. At the same time, higher requirements are being placed on the printing quality and production efficiency of bottle caps. A bottle cap is a device that fits with the bottle body to form a certain closed space. In the production and processing of bottle caps, processes such as injection molding, cooling, inspection, and packaging are required. After the bottle cap is injection molded and cooled, it is first transferred to a conveyor mechanism by a transfer mechanism. The conveyor mechanism will then transport the bottle cap smoothly to a specific position according to a predetermined path, preparing it for the subsequent printing and processing stage.

[0003] Existing feeding and conveying devices cannot accurately convey bottle caps of different sizes when feeding them to printing equipment, as bottle caps are designed to fit various food packaging and have different diameters. If the feeding device cannot flexibly adapt to these size changes, bottle cap conveying jams and positional deviations can easily occur, which in turn affects the normal operation of the printing equipment and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned shortcomings. Due to the difference in bottle cap diameter, it is difficult to transport bottle caps of different sizes. If the feeding device cannot flexibly adapt to these changes, it is easy to cause bottle cap conveying jams and positional deviations, which will affect the normal operation of printing equipment and reduce production efficiency.

[0005] To achieve the above objectives, this utility model provides a guide feeding unit for bottle cap printing, including a support body, a gear and rack assembly is provided in the inner cavity of the support body, a conveyor belt is slidably connected to the surface of the gear and rack assembly, a limit component is provided at the top of the support body, a feeding component is provided at the end of the support body, and a printing device is provided directly opposite the feeding component. The feeding component is used to receive bottle caps conveyed by the conveyor belt.

[0006] The feeding assembly includes a support frame fixedly connected to the surface of the support body, a positioning arc frame fixedly connected to the top of the support frame, a sliding column fixedly connected to the inner wall of the positioning arc frame, and a sliding arc frame slidably connected to the surface of the sliding column. The positioning arc frame and the sliding arc frame have an arc structure, and their shape is adapted to the curvature of the bottle cap surface.

[0007] At the initial stage of cap feeding, the transfer mechanism precisely places the caps onto the surface of the conveyor belt. Then, the rack and pinion assembly starts working, its operation causing the conveyor belt to slide smoothly within the support structure, thus achieving the cap transport process. As the rack and pinion assembly continues to operate, the caps on the conveyor belt surface move steadily until they reach the feeding component. At this point, the caps smoothly enter the area between the positioning arc frame and the sliding arc frame. The sliding arc frame can slide flexibly on the sliding column, ensuring a tight fit between the surface of the sliding arc frame and the cap surface. The positioning arc frame and the sliding arc frame cooperate to position the caps between them. The arc design of the positioning arc frame increases the contact area with the cap surface, making the fixation more secure and reliable.

[0008] As a further improvement to this technical solution, the limiting component includes a first connecting block fixedly connected to the top of the support body, and a limiting rod is slidably connected to the inner wall of the first connecting block;

[0009] A positioning connecting block is fixedly connected to the top of the support body, and a positioning rod is fixedly connected to the inner wall of the positioning connecting block. The positioning rod and the limiting rod are located above the conveyor belt.

[0010] By sliding the limiting rod closer to the positioning rod, the limiting rod and the positioning rod can form a relatively narrow channel above the conveyor belt, which can limit the bottle cap during the conveying process, thereby ensuring that the bottle cap is stably conveyed along the predetermined trajectory.

[0011] As a further improvement to this technical solution, an inclined frame is fixedly connected to the top of the support frame, the inclined frame is located below the conveyor belt, and the positioning arc frame is located at the bottom of the inclined frame.

[0012] A cylinder is fixedly connected to the top of the support frame. The cylinder is fixed to the top of the support frame by a bracket, and the output end of the cylinder is fixedly connected to the surface of the sliding arc-shaped frame.

[0013] An electric telescopic rod is fixedly connected to the top of the support frame, and the output end of the electric telescopic rod slides between the positioning arc frame and the sliding arc frame;

[0014] The bottle cap is conveyed to the end via a conveyor belt and slides down guided by the inclined frame below, falling between the positioning arc frame and the sliding arc frame located at the bottom of the inclined frame. Driven by a cylinder, the sliding arc frame slides along a sliding column according to the diameter of the bottle cap, approaching the positioning arc frame. The two work together to fix the bottle cap, ensuring its position is aligned with the printing equipment. The arc design of the positioning arc frame enhances the stability of the fixation. When the bottle cap needs to be delivered to the printing equipment, the electric telescopic rod is activated, and its output end pushes the bottle cap, completing the feeding process from the feeding component to the printing equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this bottle cap printing guide feeding unit, a limiting component restricts the position of the bottle cap during the conveying process, ensuring that the bottle cap always moves along a preset trajectory. When the conveyor belt transports the bottle cap between the positioning arc frame and the sliding arc frame, the sliding arc frame can slide on the sliding column to adapt to bottle caps of different diameters used for various food packaging. This avoids the situation where the bottle cap cannot be aligned with the printing equipment due to size issues. At the same time, both the positioning arc frame and the sliding arc frame adopt an arc structure that matches the curvature of the bottle cap surface. The two work together to ensure that the bottle cap is always located between the positioning arc frame and the sliding arc frame, thus avoiding the situation where the bottle cap cannot be accurately aligned with the printing equipment.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figures 1-5 As shown, this embodiment provides a guide feeding unit for bottle cap printing, including a support body 1, a gear and rack assembly 11 is provided in the inner cavity of the support body 1, a conveyor belt 12 is slidably connected to the surface of the gear and rack assembly 11, a limit assembly 2 is provided at the top of the support body 1, a feeding assembly 3 is provided at the end of the support body 1, and a printing device 4 is provided directly opposite the feeding assembly 3. The feeding assembly 3 is used to receive the bottle caps conveyed by the conveyor belt 12.

[0030] The feeding assembly 3 includes a support frame 31 fixedly connected to the surface of the support body 1, a positioning arc frame 33 fixedly connected to the top of the support frame 31, a sliding column 330 fixedly connected to the inner wall of the positioning arc frame 33, and a sliding arc frame 34 slidably connected to the surface of the sliding column 330. The positioning arc frame 33 and the sliding arc frame 34 have an arc structure, and their shape is adapted to the curvature of the bottle cap surface.

[0031] First, the bottle cap is placed on the surface of the conveyor belt 12 using the transfer mechanism. Then, the gear and rack assembly 11 starts to work, driving the conveyor belt 12 to slide in the inner cavity of the support body 1, thereby realizing the conveying of the bottle cap. During this conveying process, the limiting component 2 will restrict the position of the bottle cap, ensuring that the bottle cap always moves along the preset trajectory and avoiding positional deviation from the predetermined path. As the gear and rack assembly 11 continues to operate, the bottle cap on the surface of the conveyor belt 12 moves accordingly until it reaches the feeding component 3. At this time, the bottle cap will be conveyed between the positioning arc frame 33 and the sliding arc frame 34. Since the sliding arc frame 34 slides on the sliding column 330, it can adapt to bottle caps of different diameters, so that its surface is in close contact with the bottle cap surface. The positioning arc frame 33 and the sliding arc frame 34 cooperate with each other to firmly fix the bottle cap. Since the positioning arc frame 33 adopts an arc design, it increases the contact area with the bottle cap surface, thereby improving the stability and reliability of fixing the bottle cap.

[0032] The improvement in this embodiment is as follows:

[0033] Considering that existing feeding and conveying devices cannot accurately convey bottle caps of different sizes when feeding them to printing equipment, given that bottle caps are designed to fit various food packaging and have varying diameters, the feeding device cannot flexibly adapt to these size variations. This can easily lead to issues such as cap jamming and positional deviation, affecting the normal operation of the printing equipment and reducing production efficiency. Therefore, the limiting component 2 restricts the position of the bottle caps during the conveying process, ensuring that the bottle caps always move along a preset trajectory. The conveyor belt 12 then transports the bottle caps to... When positioned between the positioning arc frame 33 and the sliding arc frame 34, the sliding arc frame 34 can slide on the sliding column 330 to accommodate bottle caps of different diameters used in various food packaging. This avoids the situation where the bottle cap cannot be aligned with the printing equipment 4 due to size issues while rolling between the positioning arc frame 33 and the sliding arc frame 34. At the same time, both the positioning arc frame 33 and the sliding arc frame 34 adopt an arc structure that matches the curvature of the bottle cap surface. The two work together to ensure that the bottle cap is always positioned between the positioning arc frame 33 and the sliding arc frame 34, thereby preventing the bottle cap from being accurately aligned with the printing equipment 4.

[0034] In order to enable the limiting component 2 to restrict the position of the bottle cap on the surface of the conveyor belt 12 and prevent the bottle cap from deviating from the predetermined track, it is necessary to further disclose the parts of the limiting component 2. Therefore, the limiting component 2 includes a first connecting block 21 fixedly connected to the top of the support body 1, and a limiting rod 210 is slidably connected to the inner wall of the first connecting block 21.

[0035] A positioning connecting block 22 is fixedly connected to the top of the support body 1. A positioning rod 220 is fixedly connected to the inner wall of the positioning connecting block 22. The positioning rod 220 and the limiting rod 210 are located above the conveyor belt 12. By sliding the limiting rod 210 to bring it close to the positioning rod 220, the limiting rod 210 and the positioning rod 220 can form a relatively narrow channel above the conveyor belt 12, which plays a limiting role on the bottle cap during the conveying process, thereby ensuring that the bottle cap is stably conveyed along the predetermined trajectory.

[0036] To enable the positioning arc frame 33 and the sliding arc frame 34 to receive bottle caps falling from the conveyor belt 12, a tilting frame 32 is fixedly connected to the top of the support frame 31. The tilting frame 32 is located below the conveyor belt 12, and the positioning arc frame 33 is located at the bottom below the tilting frame 32. When the bottle cap moves to the end of the conveyor belt 12, because the tilting frame 32 is located below the conveyor belt 12, the bottle cap will slide down the inclined surface of the tilting frame 32. The bottle cap that slides down will eventually fall between the positioning arc frame 33 and the sliding arc frame 34. At this time, the sliding arc frame 34 slides on the sliding column 330 and approaches the positioning arc frame 33, and adjusts its position according to the diameter of the bottle cap so that its surface contacts the bottle cap surface. The positioning arc frame 33 and the sliding arc frame 34 are used to fix the bottle cap surface, so that the position of the bottle cap corresponds exactly to the printing equipment 4. Moreover, the arc shape of the positioning arc frame 33 increases the contact area with the bottle cap and improves the stability of the fixation.

[0037] In order to allow the sliding arc frame 34 to slide on the surface of the sliding column 330 and approach the positioning arc frame 33 to fix the bottle cap surface, a cylinder 35 is fixedly connected to the top of the support frame 31. The cylinder 35 is fixed to the top of the support frame 31 by a bracket. The output end of the cylinder 35 is fixedly connected to the surface of the sliding arc frame 34. The operation of the cylinder 35 can drive the sliding arc frame 34 to slide on the surface of the positioning arc frame 33, thereby approaching the positioning arc frame 33 and restricting the position of the bottle cap.

[0038] To ensure the smooth transport of bottle caps between the positioning arc frame 33 and the sliding arc frame 34 to the surface of the printing equipment 4, an electric telescopic rod 36 is fixedly connected to the top of the support frame 31. The output end of the electric telescopic rod 36 slides between the positioning arc frame 33 and the sliding arc frame 34. When it is necessary to transport the bottle caps fixed between the positioning arc frame 33 and the sliding arc frame 34 to the surface of the printing equipment 4, the electric telescopic rod 36 starts to work, and its output end slides between the positioning arc frame 33 and the sliding arc frame 34, pushing the bottle caps toward the printing equipment 4, thereby realizing the smooth feeding of bottle caps from the feeding assembly 3 to the printing equipment 4.

[0039] In practical use, the guide feeding unit for bottle cap printing of this utility model first moves the sliding limiting rod 210 close to the positioning rod 220. At this time, the limiting rod 210 and the positioning rod 220 can form a relatively narrow channel above the conveyor belt 12. Then, the transfer mechanism places the bottle cap on the surface of the conveyor belt 12. Subsequently, the gear and rack assembly 11 starts to work, driving the conveyor belt 12 to slide in the inner cavity of the support body 1. At this time, the bottle cap on the surface of the conveyor belt 12 will move accordingly. The bottle cap will move in the channel between the limiting rod 210 and the positioning rod 220. When the bottle cap moves to the end of the conveyor belt 12, since the tilting frame 32 is located below the conveyor belt 12, the bottle cap will follow the tilting frame. As the inclined surface of 32 slides down, the bottle cap will eventually fall between the positioning arc frame 33 and the sliding arc frame 34 because the positioning arc frame 33 is located at the bottom below the inclined frame 32. At this time, the sliding arc frame 34 slides on the sliding column 330 to approach the positioning arc frame 33 and adjusts its position according to the diameter of the bottle cap so that its surface contacts the surface of the bottle cap. The positioning arc frame 33 and the sliding arc frame 34 fix the surface of the bottle cap so that the position of the bottle cap corresponds exactly to the printing equipment 4. At this time, the electric telescopic rod 36 starts to work, and its output end slides between the positioning arc frame 33 and the sliding arc frame 34, pushing the bottle cap to move towards the printing equipment 4, thereby realizing the smooth feeding of the bottle cap from the feeding component 3 to the printing equipment 4.
