Description

Technical Field

[0001] The present invention relates to the technical field of tape packaging, and particularly to a heat-sealing discharging mechanism of a tape packaging device. Background Art

[0002] In the technical field of tape packaging, traditional tape packaging devices usually have the following defects: 1. Insufficient specification adaptability: Most devices can only package tapes of a single size. When tapes of different specifications need to be encapsulated, the entire set of packaging mechanisms needs to be replaced, which is cumbersome to operate and has low production efficiency, and cannot meet the diverse production requirements. 2. Serious waste of packaging materials: Traditional packaging methods often adopt full-wrap encapsulation, which not only consumes a large amount of protective film materials, but also lacks targeted design for the packaging of the tape sides, resulting in unnecessary cost increase. 3. Unstable heat-sealing effect: The position and temperature of existing heat-sealing mechanisms are inconvenient to adjust, and it is difficult to ensure that the protective films of tapes of different sizes can be evenly tightened, resulting in uneven packaging quality and prone to problems such as wrinkles and bubbles. 4. Low degree of automation: Feeding, film wrapping, heat-sealing and other links mostly rely on manual intervention or fixed processes, lacking a linkage adjustment mechanism, and cannot achieve full-process automation from tape size recognition to automatic adaptation of packaging parameters, restricting the improvement of production efficiency. Summary of the Invention

[0003] In order to overcome the disadvantages in the prior art that multi-specification tape encapsulation cannot be achieved and the encapsulation cost is high, the present invention proposes a heat-sealing discharging mechanism of a tape packaging device.

[0004] To achieve the above object, the present invention provides the following technical solution: A heat-sealing discharging mechanism of a tape packaging device, including a workbench and a conveyor. The conveyor is horizontally installed on the upper surface of the workbench. A number of tape brackets are equidistantly installed on the conveyor belt of the conveyor. The conveyor drives the tape brackets to move from left to right, and the tape brackets drag the tape to move. A bracket is installed at the left end of the upper surface of the workbench, and a feeding mechanism is installed at the top of the bracket. The feeding mechanism is externally connected to a reel to supply tape into the feeding mechanism. A protective film releasing mechanism and two heaters are installed on the upper surface of the workbench. The protective film releasing mechanism is located between the feeding mechanism and the heaters. The protective film releasing mechanism slews a protective film on the tape. The two heaters are symmetrically arranged before and after the outside of the conveyor. The heaters are energized to generate heat, and the high temperature tightens the protective film on the tape surface to package the tape. The purpose is to adjust the distance between the slide rails to complete the feeding of tapes of different specifications. The feeding mechanism includes an adjusting component installed at the top of the bracket. A slide table is installed on the top of the adjusting component. Four insertion rods are installed at the bottom of the slide table. By the adjusting component squeezing the insertion rods, the slide table can achieve sliding. Two symmetrically arranged slide rails are installed obliquely on the top of the slide table. When the distance between the slide rails changes, it can limit tapes of different sizes. A positioning component is installed at the right end of the slide rail to limit the tape.

[0005] Preferably, the adjusting component includes a box body installed at the top end of the bracket. A first motor is installed on the right side wall of the box body. One end of a screw rod is installed at the output end of the first motor, and the other end of the screw rod is connected to the left inner wall of the box body through a bearing. A push plate is screwed on the outer wall of the screw rod, and the box body limits the push plate by its own shape. When the screw rod rotates clockwise or counterclockwise, the screw thread rotation force of the screw rod can drive the push plate to move left or right. Two groups of symmetrically arranged chutes are opened on the left and right sides of the upper surface of the push plate, and the insertion rods are inserted into the inner cavity of the chutes.

[0006] Preferably, the chutes are obliquely distributed on the upper surface of the push plate.

[0007] Preferably, the positioning component includes a support seat installed at the right end of the slide rail. A rotatable rotating shaft is installed at the center position of the support seat through a bearing. A torsion spring is sleeved at the bottom of the outer wall of the rotating shaft. A baffle is installed at the top of the outer wall of the rotating shaft. Under the action of the torsion force of the torsion spring, the rotating shaft is driven to rotate to keep the baffle perpendicular to the slide rail.

[0008] Preferably, the purpose is to release a protective film adapted to the outer diameter of the tape to achieve the purpose of encapsulating tapes of different specifications. The protective film releasing mechanism includes a mounting plate installed on the upper surface of the workbench. A limiting component, a lifter and a rotating component are installed on the lower surface of the mounting plate from left to right in sequence. A pin is installed at the right end of the lifter. By the rotating component squeezing the pin, the lifter can rise or fall. Telescopic rods are installed on the front and back sides of the left side wall of the lifter, and a protective film releasing component is installed at the left end of the telescopic rod.

[0009] Preferably, the limiting component includes a top plate installed at the left end of the lower surface of the mounting plate. A limiting column is vertically installed on the lower surface of the top plate. A heating rod is installed at the center position of the limiting column. The heating rod is energized to heat the limiting column. A number of steel rings with equal heights are installed on the outer wall of the limiting column from top to bottom. Jacks are opened on the outer wall of the steel rings.

[0010] Preferably, the shape of the limiting column is trapezoidal, and there is a gap between the limiting column and the steel rings.

[0011] Preferably, the rotating assembly includes a damping pause knob installed at the right end of the upper surface of the mounting plate. A coaxial rotating cylinder is installed at the bottom end of the damping pause knob. A guide groove is formed on the outer wall of the cylinder, and a pin is inserted into the inner cavity of the guide groove.

[0012] Preferably, the guide grooves are distributed in a stepped shape on the outer wall of the cylinder, and are inclined between two gradients.

[0013] Preferably, the protective film releasing assembly includes a box body installed at the left end of the telescopic rod. A second motor is installed at the center position of the bottom of the box body. A rotating column is installed at the output end of the second motor. A plastic coil is installed on the outer wall of the rotating column. The second motor drives the rotating column to drive the plastic coil to rotate, so that the plastic coil releases the protective film. A positioning column is horizontally installed at the center position of the left side wall of the box body to determine the distance between the box body and the steel ring through the positioning column. A hollow plate corresponding to the position of the jack is installed at the rear end of the left side wall of the box body, so that the protective film can pass through the inner cavity of the hollow plate and the jack in sequence. A cylinder is installed on the front surface of the hollow plate. A cutter is installed at the output end of the cylinder. The cylinder drives the cutter to move backward, so that the cutter cuts off the protective film.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Intelligent adjustment of the feeding mechanism: By adjusting the components (the linkage of the first motor, screw rod, push plate and inclined chute), the distance between the two slide rails can be accurately changed; when the screw rod rotates clockwise or counterclockwise, the push plate moves left and right, and its inclined chute squeezes the insertion rod, driving the slide table and the slide rail to move closer or farther synchronously, so as to adapt to tapes of different diameters. The feeding of multi-specification tapes can be completed without replacing hardware; the baffle plate in the positioning component cooperates with the torsion spring, automatically rotates to make way when the tape is pulled by the bracket, and the baffle plate returns to block the subsequent tapes under the action of the torsion spring after the tape arrives, realizing orderly feeding and avoiding the chaos of multi-tape stacking.

[0015] 2. Dynamic matching of the protective film releasing mechanism: The rotating assembly (the damping pause knob and the guide groove of the cylinder) can drive the lifter to drive the protective film releasing assembly to move up and down, so that the plastic coil corresponds to steel rings of different heights. The trapezoidal design of the limit column and the gap of the steel ring can form circular protective films of different diameters, accurately matching the outer diameter of the tape and solving the defect of one-size-fits-all film wrapping of traditional devices.

[0016] 3. Side orientation packaging: The protective film releasing mechanism only sleeves the protective film on the side of the tape, without full wrapping, saving packaging materials compared with the traditional full encapsulation method. The heating rod heats the limit column, so that the protective film maintains a stable shape when being bent and shaped, reducing material waste caused by poor shaping.

[0017] 4. Precise cutting and adaptation: The cylinder drives the cutter to precisely cut the protective film, avoiding the errors and material losses of manual cutting; at the same time, the positioning posts automatically adjust the distance between the box body and the steel ring through the inclined plane design to ensure the accurate release path of the protective film and further improve the material utilization rate.

[0018] 5. Full-process collaborative operation: The conveyor drives the tape bracket to move at a constant speed, forming an assembly line operation with the feeding mechanism, the protective film release mechanism, and the heat sealing mechanism. The whole process from tape conveying, film wrapping to heat sealing and discharging is automated, reducing manual intervention; the electrified design of the adjustment component and the rotation component (the first motor, the damping pause knob) can complete the specification switching within a few minutes, significantly shortening the changeover time, and is suitable for flexible production scenarios with small batches and multiple varieties.

[0019] In summary, the present invention can package the side of the tape, save packaging materials, reduce production costs, and can also package tapes of different sizes, realizing multi-functional use of one machine, which is conducive to the use of tape packaging.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a technical solution: a heat-sealing discharging mechanism of a tape packaging device, as Figures 1-9 shown, including a workbench 1 and a conveyor 2. The conveyor 2 is horizontally installed on the upper surface of the workbench 1. A number of tape brackets 3 are equidistantly installed on the conveyor belt of the conveyor 2. The conveyor 2 drives the tape brackets 3 to move from left to right, so that the tape brackets 3 drag the tape to move. A bracket 4 is installed at the left end of the upper surface of the workbench 1, and a feeding mechanism 5 is installed at the top of the bracket 4. The feeding mechanism 5 is externally connected to a material tray to supply tape into the feeding mechanism 5. A protective film releasing mechanism 6 and two heaters 7 are installed on the upper surface of the workbench 1. The protective film releasing mechanism 6 is located between the feeding mechanism 5 and the heaters 7. The protective film releasing mechanism 6 sleeves a protective film on the tape. The two heaters 7 are symmetrically arranged before and after the outside of the conveyor 2. The heaters 7 are energized to generate heat, and the high temperature makes the protective film tighten on the surface of the tape to package the tape.

[0024] As a preferred solution, furthermore, the feeding mechanism 5 includes an adjusting component 51 installed on the top of the bracket 4. A sliding table 52 is installed on the top of the adjusting component 51. Four inserting rods 53 are installed at the bottom of the sliding table 52. By the adjusting component 51 squeezing the inserting rods 53, the sliding table 52 is enabled to slide. Two front-back symmetric slide rails 54 are obliquely installed on the top of the sliding table 52. When the distance between the slide rails 54 changes, it limits tapes of different sizes. A positioning component 55 is installed at the right end of the slide rail 54 to limit the tape.

[0025] As a preferred solution, furthermore, the adjusting component 51 includes a box body 511 installed at the top end of the bracket 4. A first motor 512 is installed on the right side wall of the box body 511. One end of a screw rod 513 is installed at the output end of the first motor 512, and the other end of the screw rod 513 is connected to the left inner wall of the box body 511 through a bearing. A push plate 514 is screwed on the outer wall of the screw rod 513, and the box body 511 limits the push plate 514 by its own shape. When the screw rod 513 rotates clockwise or counterclockwise, the screw thread rotational force of the screw rod 513 can drive the push plate 514 to move left or right. Two groups of front-back symmetric sliding grooves 515 are opened on the left and right sides of the upper surface of the push plate 514, and the inserting rods 53 are inserted into the inner cavity of the sliding grooves 515. Furthermore, the sliding grooves 515 are obliquely distributed on the upper surface of the push plate 514. When the push plate 514 moves left and right, the inclined surface of the sliding groove 515 can squeeze the inserting rods 53 inwards or outwards.

[0026] More specifically, when it is necessary to adjust the feeding mechanism 5 to adapt to tapes of different sizes, the first motor 512 is started through the control system to drive the screw rod 513 to rotate, driving the push plate 514 to move axially; the movement of the push plate 514 is converted into the lateral displacement of the inserting rods 53 through the inclined sliding grooves 515, so as to synchronously adjust the distance between the two slide rails 54. For example, for a large-diameter tape, control the push plate 514 to move left to expand the distance between the slide rails 54 until the tape can be stably clamped between the two slide rails; for a small-diameter tape, control the push plate 514 to move right to reduce the distance between the slide rails, realizing precise limitation of the tape.

[0027] As a preferred solution, furthermore, the sliding table 52 includes two guide rods, which are respectively installed on the left and right sides of the inner cavity of the box body 511. Slide seats are sleeved on the front and back sides of the outer walls of the guide rods. The bottom of the slide seat is installed with the inserting rods 53, and the left and right sides of the top of the slide seat are installed with the slide rails 54 through columns. Under the condition that the guide rods limit the slide seats, the slide seats move the slide rails 54.

[0028] As a preferred solution, further, the positioning assembly 55 includes a support seat 551 installed on the right end of the slide rail 54, and a rotatable shaft 552 is installed at the center position of the support seat 551 through a bearing. A torsion spring 553 is sleeved on the bottom of the outer wall of the shaft 552, and a baffle 554 is installed on the top of the outer wall of the shaft 552. The shaft 552 is driven to rotate under the torque of the torsion spring 553, so that the baffle 554 and the slide rail 54 remain in a vertical state. The left side of the baffle 554 is an inclined surface, which is conducive to the tape to drive the baffle 554 to rotate.

[0029] More specifically, in the initial state, the torsion spring 553 is in a naturally stretched state, and its torque drives the rotating shaft 552 to rotate, so that the baffle 554 and the slide rail 54 remain in a vertical state, forming a lateral barrier to the tape, preventing the tape from sliding off the right end of the slide rail 54. When the conveyor 2 drives the tape bracket 3 to move to the left, the tape bracket 3 is inserted into the center hole of the tape and pushes the tape to move to the right along the slide rail 54. The inclined surface at the front end of the tape contacts the inclined surface on the left side of the baffle 554, generating a thrust to the lower right, forcing the baffle 554 to rotate clockwise around the rotating shaft 552, and the baffle 554 rotates outward to make way, allowing the tape to pass and fall on the tape bracket 3. When the tape is completely separated from the baffle 554, the torsion of the torsion spring 553 drives the rotating shaft 552 to rotate in the opposite direction, driving the baffle 554 to quickly reset to a vertical state, forming a barrier to the subsequent tape, thereby realizing the orderly transportation of a single batch of tapes and avoiding the feeding chaos caused by the stacking of multiple tapes.

[0030] As a preferred solution, further, the protective film release mechanism 6 includes a mounting plate 61 installed on the upper surface of the workbench 1, and a limit assembly 62, a lifter 64 and a rotating assembly 63 are installed on the lower surface of the mounting plate 61 from left to right in sequence. A pin 65 is installed at the right end of the lifter 64, and the pin 65 is squeezed by the rotating assembly 63 to allow the lifter 64 to rise or fall. Telescopic rods 66 are installed on both the front and rear sides of the left side wall of the lifter 64, and a protective film release assembly 67 is installed on the left end of the telescopic rod 66. The telescopic rod 66 is elastically retractable to keep the distance between the protective film release assembly 67 and the limit assembly 62 unchanged.

[0031] As a preferred solution, further, the limiting assembly 62 includes a top plate 621 installed on the left end of the lower surface of the mounting plate 61, a limiting column 622 is vertically installed on the lower surface of the top plate 621, a heating rod 623 is installed at the center of the limiting column 622, and the heating rod 623 is energized to heat the limiting column 622 to bend the protective film and shape it, and a plurality of steel rings 624 of equal height are installed on the outer wall of the limiting column 622 from top to bottom, and a socket 625 is opened on the outer wall of the steel ring 624.

[0032] As a preferred solution, further, the limiting column 622 is in the shape of a step, and there is a gap between the limiting column 622 and the steel ring 624, so that the gap between the limiting column 622 and the steel ring 624 can create circular protective films of different diameters.

[0033] More specifically, when the protective film releasing component 67 releases the protective film, the protective film passes through the insertion hole 625 of the steel ring 624 through the hollow plate 676 and forms an annular structure around the limiting column 622. At this time: Heat setting: The heating rod 623 heats the limiting column 622, and the high temperature is conducted to the surface of the limiting column 622, so that the contacted protective film is softened by heat, bends and is shaped into a circle within the annular gap, avoiding the rebound deformation of the protective film.

[0034] Diameter self-adaptation: The height of the protective film releasing component 67 is adjusted by the rotating component 63, so that the plastic coil 674 corresponds to the steel rings 624 at different heights. For example, when packaging a large-diameter tape, the protective film releasing component 67 is lifted so that the protective film passes through the bottom steel ring, and a large-diameter circular protective film is formed by using the larger gap between it and the limiting column 622; conversely, the top steel ring is selected to form a small-diameter protective film.

[0035] Precise guidance: The insertion hole 625 of the steel ring 624 provides a fixed threading path for the protective film, ensuring the stable position of the protective film when it surrounds the limiting column 622, avoiding deviation or wrinkles, and improving the packaging film accuracy.

[0036] As a preferred solution, further, the rotating component 63 includes a damping pause knob 631 installed at the right end of the upper surface of the mounting plate 61. A coaxial rotating cylinder 632 is installed at the bottom end of the damping pause knob 631. A guide groove 633 is formed on the outer wall of the cylinder 632, and the pin 65 is inserted into the inner cavity of the guide groove 633.

[0037] As a preferred solution, further, the guide grooves 633 are distributed in a stepped manner on the outer wall of the cylinder 632, and are inclined between two gradients. When the cylinder 632 rotates, the curved surface of the guide groove 633 can squeeze the lifter 64 to move up and down, so that the protective film releasing component 67 performs position switching.

[0038] More specifically, when it is necessary to adjust the height of the protective film releasing component 67 to adapt to tapes of different sizes, the operation steps are as follows: According to the diameter of the tape, manually rotate the damping pause knob 631 to drive the rotation of the cylinder 632, so that the target stepped section of the guide groove 633 is aligned with the pin 65; the inclined transition surface of the guide groove 633 pushes the pin 65 to move in the vertical direction, driving the telescopic rod 66 and the protective film releasing component 67 to lift and lower synchronously through the lifter 64 until the plastic coil 674 corresponds to the steel ring 624 at the target height in the limiting component 62 (such as the bottom steel ring for large-diameter tapes and the top steel ring for small-diameter tapes); when the pin 65 reaches the target stepped section, the internal damping structure (such as a friction plate) of the damping pause knob 631 provides resistance to keep the cylinder 632 stationary, ensuring that the protective film releasing component 67 is stable at the target height.

[0039] As a preferred solution, furthermore, the protective film releasing component 67 includes a box body 671 installed at the left end of the telescopic rod 66. At the central position of the bottom of the box body 671, a second motor 672 is installed. The output end of the second motor 672 is installed with a rotating column 673. The outer wall of the rotating column 673 is installed with a plastic coil 674. The second motor 672 drives the rotating column 673 to drive the plastic coil 674 to rotate, so that the plastic coil 674 releases the protective film. At the central position of the left side wall of the box body 671, a positioning column 675 is horizontally installed. The distance between the box body 671 and the steel ring 624 is determined by the positioning column 675. The left side of the upper surface of the positioning column 675 is a slope. When the box body 671 rises, the positioning column 675 can automatically move to the right under the action of its own slope, so as to avoid inhibiting the rise of the box body 671. At the rear end of the left side wall of the box body 671, a hollow plate 676 corresponding to the position of the jack 625 is installed, so that the protective film can pass through the inner cavity of the hollow plate 676 and the jack 625 in sequence. A cylinder 677 is installed on the front surface of the hollow plate 676. The output end of the cylinder 677 is installed with a cutter 678. The cylinder 677 drives the cutter 678 to move backward, so that the cutter 678 cuts off the protective film.

[0040] More specifically, the second motor 672 drives the rotating column 673 to rotate. The plastic coil 674 rotates with the rotating column 673 and releases the protective film. The protective film passes through the outlet of the hollow plate 676 after being guided inside the box body 671, enters the jack 625 of the steel ring 624, and forms a ring around the limiting column 622; when the rotating assembly 63 drives the box body 671 to rise or fall, the slope of the positioning column 675 contacts the steel ring 624, and unobstructed displacement is realized through slope guidance, ensuring that the box body 671 accurately corresponds to the target steel ring 624 (such as a large-diameter tape corresponding to the bottom steel ring); after the protective film surrounds the limiting column 622 and is shaped by the heating rod 623, the cylinder 677 triggers the cutter 678 to move backward, and cuts off the protective film inside the hollow plate 676. The cut protective film falls due to gravity and is sleeved outside the tape, completing the film wrapping action.

[0041] Working principle: Step 1, the first motor 512 drives the screw 513 to rotate clockwise or counterclockwise. The screw rotation force of the screw 513 drives the push plate 514 to move left or right. The inclined surface of the chute 515 squeezes the plug rod 53 inward or outward. Under the support of the sliding table 52, the distance between the two slide rails 54 becomes smaller or larger, and the slide rails 54 feed different sizes of tapes. Step 2, as the conveyor 2 drives the tape bracket 3 to move from left to right, the tape bracket 3 is inserted into the center hole of the tape, pulling the tape to move to the right. The baffle 554 is forced to rotate. When the tape falls on the tape bracket 3, the torsion of the torsion spring 553 drives the baffle 554 to rotate back, blocking the next tape, so as to realize the sequential feeding of the tapes. Step 3: When the tape passes through the protective film releasing mechanism 6, the second motor 672 drives the rotating column 673 to drive the plastic coil 674 to rotate, so that the plastic coil 674 releases the protective film outward. Restricted by the shape of the gap between the limit post 622 and the steel ring 624, the protective film forms a circle. The heat provided by the heating rod 623 shapes the protective film. The cylinder 677 drives the cutter 678 to move backward to cut the protective film. The protective film falls under its own gravity and is sleeved outside the tape to provide packaging material for the tape. When the protective film passes through the heater 7, the protective film shrinks due to heat, so that the protective film shrinks tightly on the surface of the tape to package the tape. Step 4: When packaging tapes of different sizes is required, the damping pause knob 631 is used to drive the rotating cylinder 632 to rotate clockwise or counterclockwise, so that the rotating force of the guide groove 633 squeezes the pin 65 to descend or ascend. Under the action of the inclined surface of the positioning post 675, the box body 671 can descend or ascend, so that the plastic coil 674 can correspond to the steel rings 624 at different positions to manufacture circular protective films of different diameters. Therefore, by cooperating the feeding mechanism 5 with the protective film releasing mechanism 6, the packaging task of tapes of different sizes can be completed.
