Description
Technical Field
[0001] This utility model relates to the field of tinplate can manufacturing technology, and in particular to a tinplate sealing and feeding device. Background Technology
[0002] In the field of metal can packaging for food, pharmaceuticals, and daily necessities, automated feeding of tinplate caps is a crucial step in high-speed production lines. Currently, mainstream feeding devices generally employ a fixed hopper structure, where the caps are pre-stacked in an integral hopper or cylinder, and then separated layer by layer and transported to the processing station via a lifting mechanism. The drawback is that when the hopper is empty of caps, the entire machine must be stopped and the remaining material manually emptied before refilling with a new batch of caps. Each refill operation typically takes 3-5 minutes, leading to frequent production line interruptions and impacting production efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a tinplate cap feeding device that shortens the material change time and improves feeding efficiency.
[0004] The purpose of this utility model is achieved as follows: A tinplate cap feeding device includes a base, a cap frame, and a top material block. The base is slidably connected to the cap frame in the horizontal direction. Several sealing caps are stacked sequentially from bottom to top inside the cap frame. The cap frame includes a bottom plate and a top plate arranged opposite each other. Several stop bars are arranged between the bottom plate and the top plate, and the stop bars are arranged around the sealing caps. The top material block can reciprocate linearly along the height direction of the cap frame. The bottom plate has a clearance groove that allows the top material block to pass through, and the top plate has a clearance part that allows the sealing caps to pass through. The outer periphery of the top plate is engaged with a horizontal platform surface. A horizontal cylinder is arranged on the horizontal platform surface, and a pusher block is arranged at the output end of the horizontal cylinder. The pusher block is used to push the uppermost cap frame away from the clearance part. Two symmetrically distributed roller assemblies are arranged on the base along the sliding direction of the cap frame, and the roller assemblies are rotatably connected to the bottom plate.
[0005] In use, the modular capping frame enables the stacking and positioning of the sealing caps. The top material block rises linearly along the height direction of the capping frame to lift the top sealing cap, and the top plate clearance part allows the sealing cap to pass through. At the same time, the horizontal cylinder drives the pusher block to push the lifted sealing cap away from the clearance part, completing the single material feeding. The capping frame is horizontally slidably connected to the base, and the symmetrical roller assembly on the base is slidably connected to the bottom plate to reduce friction. When the sealing caps in the capping frame are exhausted, the empty frame can be directly removed along the sliding direction and replaced with a full frame, realizing continuous material feeding without stopping the machine.
[0006] Compared with existing technologies, the advantages of this utility model are as follows: it solves the problem of forced shutdown required by traditional fixed hoppers, effectively shortens the material change time, and significantly improves material change efficiency; the stop bar positioning and the top material block work together to ensure stable stacking of sealing covers and accurate separation of single materials, eliminating problems such as cover jamming and multiple material removal; the roller assembly reduces sliding friction, making material change operation easier, and the structure is compact and easy to maintain; it shortens the material change time to less than 30 seconds, thereby achieving continuous and stable feeding, adapting to high-speed production lines, and reducing production capacity loss.
[0007] As a further improvement of this utility model, the roller assembly includes an outer baffle and an inner baffle that are arranged at relatively intervals. A number of support wheels are arranged at equal intervals between the outer baffle and the inner baffle. A rotating shaft is provided at the center of the support wheel. The two ends of the rotating shaft are rotatably connected to the outer baffle and the inner baffle respectively through rolling bearings. The inner wall of the outer baffle abuts against the bottom plate.
[0008] As a further improvement of this utility model, it also includes a vertical motor, the output shaft of which is coaxially provided with a drive wheel, the drive wheel being connected to a driven wheel via a synchronous belt, the driven wheel being coaxially and fixedly connected to the lower end of a vertical lead screw, the vertical lead screw being sleeved with a lead screw nut, the upper end of which is rotatably mounted on a horizontal platform via a rolling bearing, the lead screw nut being fixedly connected to a lifting plate, and the top material block being fixedly connected to the upper side of the lifting plate via several support columns.
[0009] As a further improvement of this utility model, the top plate is provided with locking blocks on the left and right sides along the sliding direction of the cover frame, and the horizontal platform surface is provided with locking slots corresponding to the locking blocks.
[0010] As a further improvement of this utility model, the housing of the vertical motor is fixed on the mounting base, and two guide rods are provided on the mounting base. The upper end of the guide rod is fixedly connected to the horizontal platform surface, and a linear bearing is sleeved on the guide rod. The linear bearing is fixed on the lifting plate.
[0011] As a further improvement of this utility model, the two guide rods are symmetrically distributed on both sides of the vertical lead screw.
[0012] As a further improvement of this utility model, a column is provided between the platform surface and the mounting base, and photoelectric sensors are provided at both the upper and lower ends of the column. The lifting plate is provided with a sensing plate corresponding to the photoelectric sensors. Attached Figure Description

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.
[0021] like Figure 1-4The tinplate cap feeding device shown includes a base 1, a cap frame 2, a lifting mechanism, and a top material block 3. The upper side of the base 1 is slidably connected to the cap frame 2 in the horizontal direction. Multiple sealing caps 4 are stacked sequentially from bottom to top inside the cap frame 2. The cap frame 2 includes a bottom plate 201 and a top plate 202 arranged opposite to each other. Four stop rods 203 are arranged between the bottom plate 201 and the top plate 202, and the four stop rods 203 are arranged around the sealing caps 4. The lifting mechanism is used to drive the top material block 3 to make linear reciprocating motion along the height direction of the cap frame 2. The bottom plate 201 has a relief groove 201a that allows the top material block 3 to pass through, and the top plate 202 has a relief part that allows the sealing caps 4 to pass through. The two sides of the top plate 202 are engaged with a horizontal platform surface 15. A horizontal cylinder 5 is arranged on the horizontal platform surface 15. The output end is provided with a pusher block 6, which is used to push the uppermost cover frame 2 away from the clearance part. The base 1 is provided with two symmetrically distributed roller assemblies 7 along the sliding direction of the cover frame 2. The roller assembly 7 is rotatably connected to the base plate 201. Specifically, the roller assembly 7 includes an outer baffle 701 and an inner baffle 702 that are arranged at relatively intervals. A row of equally spaced support wheels 703 is provided between the outer baffle 701 and the inner baffle 702. A rotating shaft is provided at the center of the support wheel 703. The two ends of the rotating shaft are rotatably connected to the outer baffle 701 and the inner baffle 702 respectively through rolling bearings. The inner wall of the outer baffle 701 abuts against the base plate 201 to form a lateral constraint structure. When the cover frame 2 slides along the base 1, the outer baffle 701 can prevent the base plate 201 from moving left and right, ensuring that it moves smoothly in the preset direction.
[0022] In this embodiment, the lifting mechanism includes a vertical motor 8, with a drive wheel 9 coaxially mounted on the output shaft of the vertical motor 8. The drive wheel 9 is connected to the driven wheel 11 via a synchronous belt 10. The driven wheel 11 is coaxially fixedly connected to the lower end of the vertical lead screw. A lead screw nut 12 is sleeved on the vertical lead screw, and its upper end is rotatably mounted on the horizontal platform 15 via a rolling bearing. The lead screw nut 12 is fixedly connected to the lifting plate 13. Each top material block 3 is fixedly connected to the upper side of the lifting plate 13 via two support columns 14. The lifting plate 13 includes a T-shaped fixing part fixedly connected to the lead screw nut 12 and an E-shaped receiving part fixedly connected to the support columns 14. The bottom plate 201 has an avoidance groove 201a around the outer side of the E-shaped receiving part.
[0023] To ensure the accurate alignment of the top material block 3, the pusher block 6 and the sealing cover 4, and to avoid jamming or missing parts, a locking block 202a is provided on the left and right sides of the top plate 202 along the sliding direction of the sealing cover frame 2, and a locking groove 1501 is provided on the horizontal platform surface 15 corresponding to the locking block 202a.
[0024] The housing of the vertical motor 8 is fixed on the mounting base 16. Two guide rods 17 are provided on the mounting base 16. The upper end of the guide rods 17 is fixedly connected to the horizontal platform surface 15. A linear bearing 18 is fitted over the guide rods 17. The linear bearing 18 is fixed on the lifting plate 13. The two guide rods 17 are symmetrically distributed on both sides of the vertical screw, forming a bidirectional constraint in the vertical plane. With the linear bearing 18 fitted over the guide rods 17, the lifting plate 13 can only make pure linear reciprocating motion along the axis of the guide rods 17. The low friction characteristics of the linear bearing 18 itself minimize the risk of jamming of the sliding guide, ensuring that the lifting speed is strictly synchronized with the rotation of the screw, and ensuring the accuracy of the material being lifted.
[0025] In other embodiments, a column 19 is provided between the platform 15 and the mounting base 16. Photoelectric sensors 20 are provided at both the upper and lower ends of the column 19. A sensing plate 21 is provided on the lifting plate 13 corresponding to the photoelectric sensors 20. When the lifting plate 13 continues to rise due to motor malfunction or program error, the sensing plate 21 triggers the upper sensor, immediately cuts off the motor power and alarms to prevent the top material block 3 from being over-lifted. When the lifting plate 13 descends abnormally, the sensing plate 21 triggers the lower sensor, which also stops the machine for protection, to prevent the top material block 3 from falling or the mechanical parts from colliding.
[0026] In use, the modular cover frame 2 is installed on the base 1 via a horizontal sliding connection. The top plate 202 and the locking block 202a cooperate with the horizontal platform surface 15 and the slot 1501 to achieve precise positioning. The base plate 201 is supported by the roller assembly 7 with low friction. When the lifting mechanism is activated, the vertical motor 8 drives the driven wheel 11 to rotate the vertical screw through the synchronous belt 10. The screw nut 12 pushes the top material block 3 along the avoidance groove 201a of the base plate 201 through the lifting plate 13 and the support column 14, lifting the uppermost sealing cover 4 to the set height. The horizontal cylinder 5 drives the pushing block 6 to push the lifted sealing cover 4 away from the avoidance part to complete the loading. The top material block 3 then resets. When the sealing cover 4 in the cover frame 2 is exhausted, the empty frame is removed along the sliding direction and replaced with a full frame. The roller assembly 7 and the locking block 202a-slot 1501 work together to ensure smooth material replacement and realize continuous loading.
[0027] The advantages of this utility model are as follows: the support wheels 703 are evenly distributed between the outer baffle 701 and the inner baffle 702, forming a uniform support surface, which can distribute the weight of the cover frame 2 to the base 1, and prevent the base plate 201 from bending and deforming due to excessive local pressure. The relative spacing design of the outer baffle 701 and the inner baffle 702 provides a rigid frame constraint for the support wheels 703, preventing the support wheels 703 from shifting or loosening, and ensuring that the support force is always evenly distributed. The baffle rods 203 are distributed around the sealing cover 4, which can effectively constrain the stacking posture of the sealing cover 4, and prevent tilting, scattering or deformation caused by collision and squeezing during the material feeding process, ensuring neat stacking and accurate material picking.
[0028] The above description of the embodiments is only for the purpose of helping to understand the structure and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
