Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a transition device for preventing cap jamming on a pneumatic cap delivery trough. Background Technology

[0002] Currently, bottle caps on bottled water, beverage, and non-beverage bottling lines are mostly produced separately by specialized cap manufacturers and then delivered to the corresponding bottled water and beverage factories. Due to limitations in factory layout and production processes, there is a long distance between the cap storage or unloading room and the bottling workshop. Therefore, to meet the needs of long-distance transportation, pneumatic cap conveying troughs are usually used as cap conveying devices. They use wind power to blow the caps along the track to move them smoothly, so that the caps sorted by the cap sorting machine can be quickly and safely transported to the filling machine to complete the filling and capping process. Referring to Chinese patent publication number CN218371672U, existing pneumatic cap conveying channels mainly include a cap conveying plate for transporting bottle caps. The plate has inclined air vents, and a wind source delivers airflow to these vents to move the bottle caps on the plate. A limiting tube is installed above the conveying plate to restrain the bottle caps and counteract the upward wind force, preventing them from being blown away during transport. Its tubular structure reduces the contact area with the bottle caps, thus reducing friction. However, for ease of packaging and transport, the limiting tubes in these pneumatic cap conveying channels are usually multi-segmented, with each segment connected by connectors. Gaps are often left at the joints of adjacent segments, especially since the contact between the segment and the bottle cap is only a small line contact. Under wind pressure, the bottle caps are difficult to balance and are prone to slight deformation. When the bottle caps are conveyed to the joint and come into contact with the gap, this gap can easily jam the conveyed bottle caps, causing a cap jamming phenomenon. This hinders the movement of subsequent bottle caps and affects the transport efficiency. With the development of the times, people have higher and higher requirements for automated filling equipment. The slight cap feeding delay mentioned above will have a great impact on the operating efficiency of the entire production line, so it needs to be further improved. Utility Model Content

[0003] The purpose of this utility model is to overcome the problems existing in the prior art and provide a transition device for a pneumatic cap conveying trough. Its structure is simple and can effectively prevent bottle caps from jamming during the conveying process on the pneumatic cap conveying trough.

[0004] The transition device for the air-feeding cap groove of this utility model includes a cap-feeding plate for conveying bottle caps and a limiting tube disposed above the cap-feeding plate and abutting against the top of the bottle cap. The limiting tube includes at least a first round tube and a second round tube spliced ​​together in sequence. At the splice between the first and second round tubes, there is a connector that detachably connects the first round tube and the second round tube. The transition device also includes two transition plates symmetrically disposed on both sides of the limiting tube and opposite to the splice, which abut against the top of the bottle cap when the bottle cap passes through the splice. The transition plates are both vertically arranged along the cap-feeding direction.

[0005] As a further preferred embodiment, the bottom of the transition plate is provided with a first guide slope and a second guide slope. The first guide slope is inclined downward along the cap feeding direction, and its front end is slightly lower than the limiting tube, which is used to guide the top of the bottle cap to gradually detach from the limiting tube. The second guide slope is connected to the front end of the first guide slope and is inclined upward along the cap feeding direction, which is used to guide the top of the bottle cap to gradually abut against the limiting tube.

[0006] As a further preferred embodiment, the first guide slope and the second guide slope are connected by a horizontal transition surface, which is slightly lower than the limiting tube.

[0007] As a further preferred embodiment, the height difference between the transition surface and the bottom of the limiting tube is 0.1-0.5 mm.

[0008] As a further preferred embodiment, a mounting base is fixedly installed on the top of the limiting tube, and two transition plates are respectively fixedly installed on both sides of the mounting base.

[0009] As a further preferred embodiment, the bottom of the mounting base is provided with an arc surface that matches the limiting tube, so that the bottom of the mounting base fits snugly against the top of the limiting tube.

[0010] As a further preferred embodiment, the connector is a round tube joint adapted to the inner wall of the limiting tube, with one end of the round tube joint extending into the first round tube and fixed by bolts, and the other end extending into the second round tube and fixed by bolts.

[0011] As a further preferred option, the front and rear ends of the bottom of the transition plate are also provided with rounded chamfers.

[0012] As a further preferred option, a side guard plate is also provided above the cap feeding plate to limit the side of the bottle cap.

[0013] As a further preferred embodiment, a lifting drive assembly for driving the limit tube to rise and fall is also included.

[0014] The structure of this invention features two symmetrical transition plates positioned opposite the splice on both sides of the limiting tube. These transition plates are vertically arranged along the cap feeding direction. During cap transport using the pneumatic cap conveyor chute, as the cap approaches the splice, it enters the area of ​​the transition plates, allowing the top of the cap to abut against the bottom of the plate. The transition plates provide additional restraint to prevent the cap from being blown away. The symmetrically arranged transition plates ensure the cap remains balanced during transport, preventing it from shifting to one side due to wind force and getting stuck in the gap at the splice. They also provide more contact surface, avoiding a single line contact between the tube and the cap, thus reducing deformation caused by wind pressure and preventing the cap from getting stuck in the gap. This structure allows the cap to pass more smoothly through the splice of the limiting tube, effectively reducing cap jamming and ensuring smooth transport of the cap on the pneumatic cap conveyor chute. This improves the overall efficiency of the production line. The structure is simple, rationally designed, and easy to install. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

If the specific posture changes, the directional indication will also change accordingly.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical features of each embodiment can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should all be considered within the scope of this specification.

[0027] In this embodiment, the direction in which the bottle cap 100 moves along the cap delivery plate 1 is... Figure 1 The direction A for feeding the cover, indicated by the middle arrow, corresponds to the front-to-back direction of the transition device.

[0028] like Figures 1 to 9As shown, the transition device of the air-pumped cap trough in this embodiment includes a cap-feeding plate 1 for conveying bottle caps 100 and a limiting tube 2 disposed above the cap-feeding plate 1 and abutting against the top of the bottle cap 100. The limiting tube 2 limits the top of the bottle cap 100 to prevent it from being blown away by the wind. The limiting tube 2 includes at least a first circular tube 21 and a second circular tube 22 connected in sequence. The joint 23 between the first and second circular tubes has a function to detachably connect the first circular tube 21 and the second circular tube 22. The connecting parts; the limiting tube 2 with a circular tube structure limits the bottle cap 100, and the contact surface between the limiting tube 2 and the bottle cap 100 on the cap feeding plate 1 is an arc surface, which can reduce the contact area between the limiting tube 2 and the bottle cap 100 and reduce the friction; the transition device also includes two transition plates 3 symmetrically arranged on both sides of the limiting tube 2 and opposite to the splice 23, which are used to abut against the top of the bottle cap 100 when the bottle cap 100 passes through the splice 23. The transition plates 3 are both vertically arranged along the cap feeding direction A.

[0029] The above structure is applied in the air-pumped cap trough. By symmetrically setting two transition plates 3 on both sides of the limiting tube 2 at positions opposite to the splice 23, and the transition plates 3 on both sides are vertically set along the cap feeding direction A, when the bottle cap is transported using the air-pumped cap trough, when the bottle cap is close to the splice 23, the bottle cap enters the range of the transition plates 3, so that the top of the bottle cap can abut against the bottom of the transition plates 3. The transition plates 3 provide additional limiting effect on the top of the bottle cap to prevent the bottle cap from being blown away. The symmetrically set transition plates 3 on both sides can ensure that the bottle cap is kept in balance during transport and is not easily biased to one side by the wind force, causing the bottle cap to get stuck in the gap of the splice 23. At the same time, it can also provide more contact surface for the bottle cap, avoiding a single line contact between the round tube and the bottle cap, so as to better reduce the amount of deformation caused by the pressure of the wind force on the bottle cap, and the bottle cap is not easily stuck in the gap of the splice 23. With the above structure, the bottle cap can pass through the joint of the limiting tube more smoothly, thereby effectively reducing the occurrence of cap jamming and ensuring smooth transportation of the bottle cap on the air conveying cap groove. This is conducive to improving the operating efficiency of the entire production line. Its structure is simple, its setting is reasonable, and its installation is convenient.

[0030] In one embodiment, to make the connection between the transition plate 3 and the limiting tube 2 smoother, the bottom plane of the transition plate 3 can be made flush with the bottom of the limiting tube 2 to reduce the jamming when the bottle cap 100 passes through the splice 23. Furthermore, the front and rear ends of the bottom of the transition plate 3 can also be provided with rounded chamfers 34 to make the contact between the bottle cap 100 and the bottom of the transition plate 3 smoother, further reducing jamming.

[0031] To further prevent the cap from jamming due to contact between the cap and the gap at the joint, such as Figure 6-9At the bottom of the transition plate 3, a first guide slope 31 and a second guide slope 32 are provided. The first guide slope 31 slopes downward along the cap feeding direction A, with its front end slightly lower than the limiting tube 2, and is used to guide the top of the bottle cap 100 to gradually detach from the limiting tube 2. The second guide slope 32 is connected to the front end of the first guide slope 31 and slopes upward along the cap feeding direction A, and is used to guide the top of the bottle cap 100 to gradually abut against the limiting tube 2, thereby forming a guide structure at the bottom of the transition plate 3 that can push the bottle cap 100 away from the splicing point 23. (Refer to...) Figure 7 As shown, the first guide slope 31 slopes downwards along the cap feeding direction A, so that its front end is slightly lower than the bottom of the limiting tube 2, while its rear end can be slightly higher than the bottom of the limiting tube 2 or flush with the bottom of the limiting tube 2. When the bottle cap 100 approaches the splicing point 23 along the cap feeding direction A, the top of the bottle cap 100 will abut against the first guide slope 31 and move downwards along the slope under the guidance of the first guide slope 31, as... Figure 8 As shown, the top of the bottle cap 100 gradually detaches from the limiting tube 2, that is, the top of the bottle cap 100 abuts against the transition plates 3 on both sides instead of the limiting tube 2. At this time, the bottle cap 100 can pass through the splice 23 position while avoiding the gap between it and the splice 23. Figure 9 As shown; the second guide slope 32 is inclined upward along the cap feeding direction A, so that its rear end is slightly lower than the bottom of the limiting tube 2, while its front end can be slightly higher than the bottom of the limiting tube 2 or flush with the bottom of the limiting tube 2. When the bottle cap 100 is about to move away from the splice 23 along the cap feeding direction A, the top of the bottle cap 100 abuts against the second guide slope 32 and moves away. Figure 9 As shown, the bottle cap 100 moves upward along the inclined plane under the guidance of the second guide slope 32, gradually bringing the top of the cap 100 back into contact with the limiting tube 2, where the limiting tube 2 continues to provide restraint. This structure avoids direct contact between the bottle cap 100 and the gap at the joint 23, further preventing cap jamming. The length and position of the two inclined planes can be adjusted according to actual conditions so that the portion of the bottom of the transition plate protruding downwards from the lowest point of the limiting tube covers the gap at the joint, ensuring that the bottle cap does not contact the gap under the guidance of the inclined planes, thus achieving optimal performance.

[0032] Specifically, such as Figure 6The first guide slope 31 and the second guide slope 32 are connected by a horizontal transition surface 33. The transition surface 33 is slightly lower than the limiting tube 2, and provides a certain buffering effect, making the bottle cap move more smoothly when it abuts against the bottom of the transition plate. The first guide slope 31 and the second guide slope 32 can be symmetrically arranged with respect to the transition surface 33, thereby forming a structure similar to an inverted isosceles trapezoid at the bottom of the transition plate, ensuring that the bottle cap has a consistent amount of movement when approaching or moving away from the splice, further reducing the possibility of the bottle cap getting stuck. The height difference L between the transition surface 33, which is the lowest point of the bottom of the transition plate, and the lowest point of the limiting tube 2 can be adjusted to a smaller value according to the actual situation, so as to reduce the inclination of the two slopes relative to the horizontal plane, making the slopes gentler, thereby reducing the undulations during the movement of the bottle cap and making the bottle cap move more smoothly; in a specific embodiment, the height difference L between the transition surface 33 and the bottom of the limiting tube 2 is set to 0.1-0.5mm.

[0033] In one embodiment, such as Figure 3 , Figure 4 As shown, the connector is a round pipe joint 5 adapted to the inner wall of the limiting tube 2. During installation, one end of the round pipe joint 5 extends into the first round tube 21 and is fixed by bolt 7, and the other end extends into the second round tube 22 and is fixed by bolt 7. As a further preferred embodiment, the specific installation method of the transition plate 3 on both sides of the limiting tube 2 can be referred to Figure 5 As shown, a mounting base 4 is fixedly installed on the top of the limiting tube 2, and two transition plates 3 are fixedly installed on both sides of the mounting base 4 respectively. Specifically, the mounting base 4 has screw holes 42 on both the left and right sides, and the transition plates 3 on both sides have screw holes 35 corresponding to screw holes 42. After screw holes 1 and 2 are aligned, they are connected together by bolts 7 to fix the transition plates 3 to the side of the mounting base 4. Screw holes 43 are provided on both the front and rear sides of the mounting base 4 along the cover feeding direction A. Screw holes 24 are provided at the splicing ends of the first round tube 21 and the second round tube 22. Screw holes 51 are provided at both the front and rear ends of the round tube joint 5. After the round tube joint 5 is inserted into the two round tubes, the two screw holes 51 of the round tube joint 5 are aligned with the screw holes 24 on the first and second round tubes respectively. Then, the two screw holes 43 on the mounting base 4 are also aligned with the screw holes 24 on the first and second round tubes respectively. After screw holes 3, 4, and 5 are aligned, they are connected together by bolts 7, thereby simultaneously completing the connection of the two round tubes and fixing of the mounting base 4. The above structure is simple and can realize the segmented connection of the limiting tube 2. It also allows the transition plate 3 to be easily and securely set on both sides of the limiting tube, and the mounting base 4 is set above the splice 23 of the limiting tube, further improving the connection effect between the first and second round tubes. In addition, the bottom of the mounting base 4 is provided with an arc surface 41 that matches the limiting tube 2, so that the bottom of the mounting base 4 fits snugly against the top of the limiting tube 2, thereby making the mounting base 4 more stably fixed on the top of the limiting tube 2 and reducing the possibility of displacement.

[0034] In addition, to provide a limit on the left and right sides of the bottle cap, a side guard plate 6 for limiting the side of the bottle cap can be provided above the cap feeding plate 1. The side guard plate 6 can be installed on the cap feeding plate 1 by means of a bracket (not shown in the figure). It is set on the left and right sides of the bottle cap 100 and abuts against the bottle cap. Different types of side guard plates can be selected according to the diameter, height and other factors of the bottle cap, and the position of the side guard plate can be adjusted accordingly to better limit the horizontal left and right directions of the bottle cap.

[0035] As a further preferred embodiment, a lifting drive assembly (not shown in the figure) can be provided for driving the limiting tube 2 to rise and fall. The transition plates 3 installed on both sides of the limiting tube 2 can rise and fall together with the limiting tube 2, so that both the limiting tube 2 and the transition plates 3 can adapt to bottle caps of different thicknesses, ensuring that they can play a good limiting role for different bottle caps. The lifting drive assembly can be any lifting assembly commonly used in the art. Optionally, the lifting drive assembly includes an adjusting rod and a knob. One end of the adjusting rod is connected to the limiting tube, and the other end cooperates with the knob. By rotating the knob, the adjusting rod can drive the limiting tube to rise and fall. Exemplarily, the adjusting rod and the knob can be used to achieve the lifting and falling by a cam lifting principle or by a gear and rack principle. These will not be described in detail here.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
