Description

Technical Field

[0001] This application relates to the technical field of automated tube supply, and more particularly to a tube supply lifting mechanism for an intubation machine. Background Technology

[0002] Glass tube insertion machines are commonly used automated feeding equipment in the glass product manufacturing process. Their main function is to continuously transport glass tubes to designated workstations and complete subsequent insertion processing. To achieve continuous supply of glass tubes, existing equipment typically uses conveyor belts combined with baffle or curved plate structures to form multiple storage spaces. The glass tubes are gradually transported to the discharge position by the conveying mechanism, and then the lifting mechanism is used to transport the glass tubes to the processing station.

[0003] However, the storage space in existing supply systems is usually a fixed structure. When different specifications of glass tubes need to be switched during production, the fixed storage space is difficult to accommodate different specifications of glass tubes due to the difference in their outer diameter. When the storage space is too large, multiple glass tubes may enter the same storage area at the same time; when the storage space is too small, the glass tube conveying may be obstructed, resulting in poor equipment adaptability.

[0004] Secondly, existing supply pipe mechanisms typically lack an effective single-tube separation structure at the end of the conveying process. When multiple glass tubes arrive at the discharge position simultaneously, two or more glass tubes may enter the lifting area at the same time. This causes the lifting mechanism to lift multiple glass tubes at once, resulting in mutual squeezing, collision, or even breakage between the glass tubes, which in turn leads to malfunctions such as jamming and machine shutdown.

[0005] Furthermore, most existing lifting mechanisms only have simple lifting functions and lack a guiding structure that matches the conveying mechanism. When the lifting mechanism resets, subsequent glass tubes cannot smoothly enter the feeding position, which can easily lead to problems such as glass tube accumulation, unstable feeding cycle, and poor feeding continuity, affecting equipment operating efficiency and production stability. Summary of the Invention

[0006] This application aims to at least partially address one of the technical problems in the related art.

[0007] Therefore, one objective of this application is to propose a tube feeding and lifting mechanism for a tube insertion machine. By setting an adjustable baffle assembly, a top material baffle, and a tube support component, it can realize the adaptive feeding and automatic single-tube separation of glass tubes of different specifications, avoid tube breakage, jamming, and machine stoppage caused by multiple glass tubes entering the lifting station at the same time, and improve the continuity, stability, and operating efficiency of glass tube feeding.

[0008] To achieve the above objectives, a first aspect of this application provides a tube feeding and lifting mechanism for a tube insertion machine, comprising a frame, a conveyor belt, a bending plate, two adjustable baffle assemblies, two tube support components, and two top baffles, wherein...

[0009] The conveyor belt is arranged along the inclined surface of the frame, and a drive mechanism for the conveyor belt is also provided inside the frame.

[0010] Multiple curved plates are equally spaced on the conveyor belt, and each curved plate has an internal receiving space for lifting and transferring the glass tube.

[0011] Two adjustable baffle assemblies are disposed opposite to each other on two outer sides of the bottom of the frame, and the positions of the adjustable baffle assemblies and the conveyor belt inlet correspond to each other;

[0012] The adjustable baffle assembly and the bearing surface of the conveyor belt form an adjustable feed gap, which is used to initially limit the number of glass tubes entering the receiving space.

[0013] The two material tube bracket components are disposed opposite to each other on the two outer sides of the top of the frame;

[0014] The two top material baffles are arranged opposite each other on the inner side of the top of the frame.

[0015] In addition, the tube supply and lifting mechanism of the intubation machine proposed in this application may also have the following additional technical features:

[0016] In one embodiment of this application, the adjustable baffle assembly includes a top plate, multiple adjusting brackets, and multiple fixing bolts, wherein,

[0017] The top plate is parallel to the conveyor belt at the conveying angle;

[0018] Multiple adjustment frames are installed between the frame body and the top plate to adjust the feeding gap between the top plate and the top of the curved plate;

[0019] Each of the adjustment frames has an adjustment hole, and each of the adjustment frames is equipped with a fixing bolt for locking and fixing the adjusted position.

[0020] In one embodiment of this application, the material tube bracket component includes a bracket support, a connecting rod, a rack, a limiting block, and a gear, wherein,

[0021] The gear is mounted on the frame, and a drive motor for rotating the gear is installed inside the frame;

[0022] The frame is equipped with limit blocks, and the bottom of the bracket is connected to a connecting rod.

[0023] The rack is installed in the middle of the connecting rod, and the rack and the gear mesh with each other;

[0024] The bracket is equipped with a guide structure, and the guide structure makes an angle of 30° with the horizontal direction.

[0025] In one embodiment of this application, the top baffle is a sheet-like structure;

[0026] The top of the top baffle consists of two inclined surfaces; the two inclined surfaces extend downwards from the top to the sides to a preset height, in order to guide the glass tube in the front curved plate receiving space to be transported to the rear receiving space.

[0027] The preset height is the sum of the outer diameter of the glass tube and the distance between the surface of the conveyor belt.

[0028] In one embodiment of this application, the included angle between the inclined surface of the top baffle and the discharge direction is -10°.

[0029] In one embodiment of this application, the bent plate is in the shape of any one of L-shape, U-shape and V-shape to form a recess for accommodating the glass tube.

[0030] In one embodiment of this application, the connection between the bracket and the connecting rod is any one of pin, magnetic attraction, and screw fixing.

[0031] The intubation machine tube supply and lifting mechanism of this application has the following beneficial effects:

[0032] 1. By installing adjustable baffle components at the conveyor belt inlet at the bottom of the frame, the physical gap at the inlet can be changed, enabling targeted interception and flow restriction of glass tubes with different outer diameters. This avoids multiple tubes entering simultaneously due to excessively large capacity, and also prevents conveying obstruction due to insufficient capacity, allowing a single tube supply mechanism to directly adapt to various specifications of glass tubes.

[0033] 2. By installing top baffles on the inner side of the top of the frame, when multiple glass tubes are conveyed to this area by the bending plate, the foremost glass tube enters the supporting area, while the excess glass tubes behind are restrained by the inclined surface of the top baffles and retract into the rear receiving space by gravity. This structure achieves forced single-tube separation at the end of the conveying process, avoiding mechanical interference, crushing breakage, and equipment downtime caused by the material tube support component lifting multiple glass tubes at once.

[0034] 3. By setting up a material tube support component consisting of gears, racks, connecting rods, and brackets, stable receiving and lifting of glass tubes can be achieved. At the same time, the bracket reset process guides subsequent glass tubes into the feeding position, improving the continuity of feeding and the stability of conveying.

[0035] 4. Through the coordinated operation of the adjustable baffle assembly, the top baffle, and the tube support components, a continuous feeding cycle of "feeding screening - bending plate conveying - single tube separation - support lifting - support reset" is formed, realizing stable single tube conveying and improving the operating efficiency and automation level of the tube insertion machine.

[0046] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0047] This application addresses the core technical deficiencies of existing tube insertion machines, such as poor compatibility of tube supply mechanisms, lack of single-tube separation function, lack of guidance for lifting and resetting, poor feeding stability, and high failure rate. It proposes targeted technical improvement solutions to overcome the many shortcomings of existing technologies and improve the overall performance and production adaptability of the equipment.

[0048] The tube supply and lifting mechanism of the intubation machine according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the tube feeding and lifting mechanism of the tube insertion machine in this application embodiment may include a frame 4, a conveyor belt 7, a bending plate 8, two adjustable baffle assemblies 1, two tube support components 3, and two top material baffles 2.

[0050] The conveyor belt 7 is arranged along the inclined surface of the frame 4, and the frame 4 is also equipped with a drive mechanism for the conveyor belt 7. It should be noted that the frame 4 provides a support and fixing foundation for the overall mechanism. The inclined conveyor belt 7 can use gravity to assist in the transport of the glass tube. At the same time, the built-in drive mechanism can provide stable power for the continuous operation of the conveyor belt 7 and ensure the continuity of the glass tube transport.

[0051] It should be noted that the aforementioned conveyor belt 7 can be intermittently started and stopped, and transported in segments to facilitate the transfer of glass tubes.

[0052] The frame 4 may be equipped with a guide rod 6, which is used to place and receive the glass tube to be transferred.

[0053] like Figure 6 As shown, the frame 4 is equipped with a shielding box 5 that faces the return surface of the conveyor belt 7, which can prevent tools and other foreign objects from being rolled in.

[0054] Multiple curved plates 8 are equally spaced on the conveyor belt 7, and each curved plate 8 has an internal receiving space for lifting and transferring the glass tube.

[0055] It should be noted that multiple equally spaced curved plates 8 can form an independent single conveying station. The glass tubes are individually supported by the internal space of the curved plates 8, avoiding the stacking and collision of too many glass tubes, and realizing the orderly lifting and progressive conveying of the glass tubes.

[0056] Furthermore, the shape of the bending plate 8 can be any of L-shaped, U-shaped, and V-shaped to form a recess for accommodating the glass tube. All of the above structures can stably adapt to cylindrical glass tubes. The V-shaped bending plate 8 has an automatic centering function, the U-shaped bending plate 8 provides better wrapping and limiting effects, and the L-shaped bending plate 8 is easier to process and assemble. These can be flexibly selected according to the actual production scenario.

[0057] like Figure 1 As shown, the two adjustable baffle assemblies 1 are disposed opposite to each other on the two outer sides of the bottom of the frame 4, and the positions of the adjustable baffle assemblies 1 and the feed inlet of the conveyor belt 7 correspond to each other;

[0058] It should be noted that, in this embodiment, the two sets of adjustable baffle assemblies 1 arranged opposite to each other can form a limiting structure from both sides of the feed inlet, precisely corresponding to the feeding station, and laterally limiting the glass tube entering the conveyor belt 7, such as... Figure 7 As shown.

[0059] Meanwhile, an adjustable baffle assembly 1 and the bearing surface of the conveyor belt 7 form a feed gap that can be adjusted to change size, which is used to initially limit the number of glass tubes entering the receiving space.

[0060] Specifically, staff can adjust the size of the feeding gap according to the diameter of the glass tube to be conveyed and the conveying requirements, so as to adapt to the single or quantitative feeding requirements of different specifications of glass tubes and avoid the problem of glass tubes piling up during feeding.

[0061] In one embodiment of this application, such as Figure 2 As shown, the adjustable baffle assembly 1 includes a top plate 11, multiple adjustment frames 12 and multiple fixing bolts 13.

[0062] The top plate 11 and the conveyor belt 7 are parallel in their conveying angles.

[0063] Understandably, this setup ensures that the baffle plate fits snugly against the glass tube's conveying trajectory, preventing scratches and abrasions to the glass tube wall during transport and guaranteeing smooth feeding.

[0064] Multiple adjustment frames 12 are installed between the frame 4 and the top plate 11 to adjust the feeding gap between the top plate 11 and the top of the curved plate 8; each adjustment frame 12 is provided with an adjustment hole 121 and each adjustment frame 12 is equipped with a fixing bolt 13 for locking and fixing the adjusted position.

[0065] In order to complete the single-pipe separation and lifting discharge at the end of the conveying process, the two material pipe bracket components 3 are respectively arranged on the two outer sides of the top of the frame 4;

[0066] The two top baffles 2 are arranged opposite to each other on the inner side of the top of the frame 4, thereby, together with the material tube bracket component 3, realizing the automatic unloading and sorting of excess glass tubes at the end, and the two work together to complete the precise discharge operation of a single glass tube.

[0067] Among them, such as Figure 3 As shown, the top baffle 2 is a sheet-like structure that fits the installation space at the top of the frame 4. It has no extra obstruction structure and will not interfere with the normal transportation of the glass tube.

[0068] The top of the top baffle 2 consists of two inclined surfaces; the two inclined surfaces extend downwards from the top to a preset height b, as shown below. Figure 4 As shown, it is used to guide the glass tube in the receiving space of the front curved plate 8 to be transferred to the receiving space in the rear.

[0069] The preset height is the sum of the outer diameter of the glass tube and the distance to the surface of the conveyor belt 7. This setting ensures that the normal discharge of a single glass tube is not obstructed, while also limiting and blocking excess stacked glass tubes, thus guaranteeing the sorting effect.

[0070] In one embodiment of this application, such as Figure 4 As shown, the angle between the inclined surface of the top baffle 2 and the discharge direction is -10°.

[0071] It should be noted that in the above embodiment, the included angle of -10° means that the inclined surface of the top material baffle 2 is inclined downward by 10° along the glass tube discharge direction (point a in the figure).

[0072] When multiple glass tubes are conveyed to the end by the conveyor belt 7, the single glass tube at the front can slide down the inclined plane and enter the material tube bracket component 3. If there is a second material tube approaching from behind, it will be pushed back by the negative angle of the top material baffle and re-enter the space of the bending plate 8. Without the need for additional power and sensor assistance, the single glass tube can be passively separated, solving the problems of tube breakage, material jamming, and equipment alarm shutdown caused by the synchronous lifting of multiple tubes.

[0073] In one embodiment of this application, such as Figure 5 As shown, the material tube support component 3 includes a support 31, a connecting rod 32, a rack 33, a limiting block 34, and a gear 35. It provides stable power and structural support for the lifting and feeding of the glass tube.

[0074] The gear 35 is mounted on the frame 4, and a drive motor for rotating the gear 35 is provided inside the frame 4.

[0075] Understandably, the rotational power is provided by the drive motor, which drives the gear 35 to operate stably.

[0076] The frame 4 is provided with a limit block 34; it should be noted that the limit block 34 and the gear 35 are used to limit the movement of the connecting rod 32.

[0077] The bottom of the bracket support 31 is connected to a connecting rod 32; it should be noted that the dimensions of the bracket support 31 are designed to stably accommodate only one glass tube at a time.

[0078] The rack 33 is installed in the middle of the connecting rod 32, and the rack 33 and the gear 35 mesh with each other;

[0079] Specifically, through the precise meshing transmission of gear 35 and rack 33, the rotational motion of gear 35 is converted into the linear reciprocating motion of connecting rod 32, which in turn drives the bracket 31 to achieve smooth lifting and lowering, completing the glass tube lifting, feeding and resetting actions.

[0080] It should be noted that the bracket support 31 is provided with a guide structure, and the angle between the guide structure and the horizontal direction is 30°.

[0081] The 30° inclined guide structure is a triangular flow guide slope, which can accurately support a single glass tube when the bracket is carrying the 31 lifting and feeding, ensuring stable positioning;

[0082] Meanwhile, during the descent and reset process of the bracket bearing 31, the inclined surface can guide the subsequent glass tubes to slide smoothly to the waiting position, providing a smooth unloading trajectory for excess glass tubes, avoiding squeezing and scratching of the glass tubes, and greatly reducing the glass tube breakage rate.

[0083] It should be noted that the aforementioned 30° tilt angle is used to guide the lower glass tube when two glass tubes are stacked along the conveyor belt 7 in a curved plate 8 (longitudinal direction). (The aforementioned adjustable baffle assembly 1 is used to limit the number of glass tubes in the transverse direction of the curved plate 8). The number of glass tubes inside the curved plate 8 is limited by the distance between two adjacent curved plates 8.

[0084] In one embodiment of this application, the connection between the bracket support 31 and the connecting rod 32 is any one of pin, magnetic attraction, and screw fixing.

[0085] It should be noted that the above-mentioned pin, magnetic, and screw connection methods are all quick-disassembly structures. Among them, the pin type has the highest disassembly efficiency, the magnetic type is convenient and jam-free for alignment, and the screw type has stronger stability. When changing to produce glass tubes with different outer diameters, only the bracket bearing 31 with the corresponding bearing specification needs to be disassembled and replaced. There is no need to modify the core structure such as the conveyor belt 7, bending plate 8, and top material baffle 2, which greatly shortens the equipment downtime for changeover and reduces manual debugging costs.

[0086] Specifically, when the glass tube enters the conveyor belt 7 with the feed end of the equipment, the feed gap adjusted by the adjustable baffle assembly 1 completes the initial screening, removing the horizontally stacked glass tubes; the sorted glass tubes are conveyed to the end top baffle 2 position by the inclined conveyor belt 7 and the equally spaced curved plates 8. Through the sorting action of the -10° inclined top baffle 2, the excess glass tubes are automatically retracted and reset, and only a single glass tube is on the bracket support 31 of the tube support component 3. At this time, the conveyor belt 7 stops driving.

[0087] Subsequently, the drive motor drives the gear 35 and rack 33 to rotate, driving the support bracket 31 to rise and complete the lifting and feeding of a single glass tube; after the feeding is completed, the support bracket 31 descends, the gear 35 stops rotating, the conveyor belt 7 drives again, and the excess glass tubes are conveyed to rise and complete the unloading and sorting again, forming a stable and continuous "preliminary screening - gravity single tube separation - lifting and feeding - reset and standby - surplus tube circulation" operation process.

[0088] In summary, the intubation machine tube supply and lifting mechanism of this application embodiment is as follows:

[0089] 1. By setting an adjustable baffle assembly 1 at the feed inlet of the conveyor belt 7 at the bottom of the frame 4, the physical gap at the feed point can be changed, enabling targeted interception and flow restriction of glass tubes with different outer diameters. This avoids the simultaneous entry of multiple tubes due to excessively large capacity, and also prevents conveying obstruction due to insufficient capacity, allowing a single tube supply mechanism to directly adapt to various specifications of glass tubes.

[0090] 2. By installing top baffles 2 on the inner side of the top of the frame 4, when multiple glass tubes are conveyed to this area by the bending plate 8, the foremost glass tube enters the lifting area, while the excess glass tubes behind are restrained by the inclined surface of the top baffles 2 and retreat to the rear receiving space by gravity. This structure achieves forced single-tube separation at the end of the conveying process, avoiding mechanical interference, crushing breakage, and equipment downtime caused by the material tube bracket component 3 lifting multiple glass tubes at once.

[0091] 3. By setting up a material tube support component 3 consisting of a gear 35, a rack 33, a connecting rod 32, and a support bracket 31, the glass tube can be stably received and lifted for transport. At the same time, the subsequent glass tubes are guided into the feeding position by the bracket reset process, thereby improving the continuity of feeding and the stability of transport.

[0092] 4. Through the coordinated operation of the adjustable baffle assembly 1, the top baffle 2, and the tube support component 3, a continuous feeding cycle of "feeding screening—bending plate conveying—single tube separation—support lifting—support reset" is formed, achieving stable single-tube conveying of glass tubes and improving the operating efficiency and automation level of the tube insertion machine.
