Description

Technical Field

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

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

The shaft is driven to rotate under the torsion force of the torsion spring, so that the baffle and the slide rail remain in a vertical state.

[0009] Preferably, the purpose is to release a protective film corresponding to the outer diameter of the tape to achieve the purpose of packaging tapes of different specifications. The protective film release mechanism includes a mounting plate installed on the upper surface of the workbench, and the lower surface of the mounting plate is installed with a limit assembly, a lifter and a rotating assembly from left to right. A pin is installed at the right end of the lifter, and the pin is squeezed by the rotating assembly to make the lifter rise or fall. Telescopic rods are installed on the front and rear sides of the left side wall of the lifter, and a protective film release assembly is installed at the left end of the telescopic rod.

[0010] Preferably, the limiting assembly 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, and the heating rod is energized to heat the limiting column, and the outer wall of the limiting column is installed with several steel rings of equal height from top to bottom, and the outer wall of the steel ring is provided with a socket.

[0011] Preferably, the limiting column is in a stepped shape, and there is a gap between the limiting column and the steel ring.

[0012] Preferably, the rotating assembly includes a damping pause knob installed on the right end of the upper surface of the mounting plate, and a coaxially rotating drum is installed at the bottom end of the damping pause knob. A guide groove is opened on the outer wall of the drum, and a pin is inserted into the inner cavity of the guide groove.

[0013] Preferably, the guide grooves are distributed on the outer wall of the drum in a stepped manner, and are inclined between two gradients.

[0014] 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, and the rotating column is driven by the second motor to drive the plastic coil to rotate, so that the plastic coil releases the protective film, a positioning column is installed horizontally at the center position of the left side wall of the box body, and the spacing between the box body and the steel ring is determined by the positioning column, a hollow plate corresponding to the position of the socket 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 and the socket of the hollow plate in turn, a cylinder is installed on the front of the hollow plate, and a cutter is installed at the output end of the cylinder, and the cylinder drives the cutter to move backward, so that the cutter cuts the protective film.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Intelligent adjustment of the feeding mechanism: The spacing between the two slide rails can be precisely changed by adjusting the assembly (the linkage of the first motor, screw, push plate, and inclined chute). When the screw rotates clockwise or counterclockwise, the push plate moves left or right, and its inclined chute squeezes the plunger, driving the slide and rail to move closer or further away synchronously, thereby adapting to tapes of different diameters. Multiple tape specifications can be loaded without changing hardware. The baffle in the positioning assembly cooperates with the torsion spring, and automatically rotates to make way when the tape is pulled by the bracket. After the tape is in place, the baffle returns to its original position under the action of the torsion spring to block subsequent tapes, achieving orderly loading and avoiding the chaotic stacking of multiple tapes.

[0017] 2. Dynamic Matching of the Protective Film Release Mechanism: The rotating assembly (damping stop knob and drum guide groove) drives the lifter, which in turn moves the protective film release assembly up and down, aligning the plastic coil with the steel rings at different heights. The stepped design of the limit posts and the gap between the steel rings create circular protective films of varying diameters, precisely matching the outer diameter of the tape and resolving the one-size-fits-all film encapsulation drawback of traditional devices.

[0018] 3. Side-directional packaging: The protective film release mechanism only applies protective film to the side of the tape, eliminating the need for full wrapping. This saves packaging materials compared to traditional full packaging methods. The heating rod heats the limit posts to keep the protective film in a stable shape when bent and shaped, reducing material waste caused by poor shaping.

[0019] 4. Precise cutting and adaptation: The cylinder-driven cutter accurately cuts the protective film, avoiding the errors and material loss of manual cutting; at the same time, the positioning column automatically adjusts the distance between the box body and the steel ring through the bevel design, ensuring the accurate release path of the protective film and further improving material utilization.

[0020] 5. Full-process collaborative operation: The conveyor drives the tape carrier to move at a constant speed, forming an assembly line operation with the loading mechanism, protective film release mechanism, and heat sealing mechanism. The entire process from tape conveying and wrapping to heat sealing and discharging is automated, reducing manual intervention. The motorized design of the adjustment component and the rotating component (the first motor and the damping pause knob) can complete specification switching within minutes, significantly shortening the changeover time and being suitable for flexible production scenarios with small batches and multiple varieties.

[0021] In summary, the present invention can package the side of the tape, saving packaging materials and production costs, and can also package tapes of different sizes, achieving multi-purpose use of one machine, which is beneficial to the use of tape packaging. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The present invention provides a technical solution: a heat-sealing discharging mechanism of a tape packaging device, such as Figures 1-9 As shown, it includes a workbench 1 and a conveyor 2. The conveyor 2 is horizontally installed on the upper surface of the workbench 1. Several tape holders 3 are equidistantly installed on the conveyor belt of the conveyor 2. The conveyor 2 drives the tape holder 3 to move from left to right, so that the tape holder 3 drags 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 on the top of the bracket 4. The feeding mechanism 5 is externally connected to a material tray to provide tape to the feeding mechanism 5. A protective film release mechanism 6 and two heaters 7 are installed on the upper surface of the workbench 1. The protective film release mechanism 6 is located between the feeding mechanism 5 and the heater 7. The protective film release mechanism 6 puts a protective film on the tape. The two heaters 7 are symmetrically arranged on the outside of the conveyor 2. The heater 7 generates heat when it is energized. The high temperature tightens the protective film on the surface of the tape to package the tape.

[0034] As a preferred solution, further, the feeding mechanism 5 includes an adjusting component 51 installed on the top of the bracket 4, a slide 52 is installed on the top of the adjusting component 51, and four insertion rods 53 are installed on the bottom of the slide 52. The adjustment component 51 squeezes the insertion rods 53 to allow the slide 52 to slide. Two front-to-back symmetrical slide rails 54 are installed at an angle on the top of the slide 52. When the distance between the slide rails 54 changes, the tapes of different sizes are limited. A positioning component 55 is installed on the right end of the slide rail 54 to limit the tape.

[0035] As a preferred solution, further, the adjustment component 51 includes a box body 511 installed at the top of the bracket 4, and a first motor 512 is installed on the right side wall of the box body 511, and one end of a screw 513 is installed on the output end of the first motor 512, and the other end of the screw 513 is connected to the left inner wall of the box body 511 through a bearing, and a push plate 514 is screwed to the outer wall of the screw 513, and the box body 511 uses its own shape to limit the push plate 514. When the screw 513 rotates clockwise or counterclockwise, the threaded rotation force of the screw 513 can drive the push plate 514 to move left or right. Two groups of symmetrical slide grooves 515 are opened on the left and right sides of the upper surface of the push plate 514, and the insertion rod 53 is inserted into the inner cavity of the slide groove 515. Furthermore, the slide groove 515 is 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 slide groove 515 can squeeze the insertion rod 53 inward or outward.

[0036] 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, driving the screw 513 to rotate, and driving the push plate 514 to move axially; the movement of the push plate 514 is converted into a lateral displacement of the insertion rod 53 through the inclined slide groove 515, thereby synchronously adjusting the distance between the two slide rails 54, for example: for large-diameter tapes, the push plate 514 is controlled to move to the left to expand the distance between the slide rails 54 until the tape can be stably clamped between the two slide rails; for small-diameter tapes, the push plate 514 is controlled to move to the right to reduce the distance between the slide rails, thereby achieving precise positioning of the tape.

[0037] As a preferred solution, further, the slide 52 includes two guide rods, which are respectively installed on the left and right sides of the inner cavity of the box 511. The front and back sides of the outer walls of the guide rods are both sleeved with slides. The bottom of the slide is installed with the plug rod 53, and the left and right sides of the top of the slide are installed with the slide rails 54 through the columns. Under the condition that the guide rods limit the slide, the slide can move relative to the slide rails 54.

[0038] As a preferred solution, further, the positioning assembly 55 includes a support seat 551 installed at 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. Under the action of the torsion force of the torsion spring 553, the shaft 552 is driven to rotate, 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 convenient for the tape to drive the baffle 554 to rotate.

[0039] More specifically, in the initial state, the torsion spring 553 is in a naturally stretched state, and its torsion 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 of the front end of the tape contacts the inclined surface of 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 return 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 loading chaos caused by the stacking of multiple tapes.

[0040] 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 the lower surface of the mounting plate 61 is installed with a limit assembly 62, a lifter 64 and a rotating assembly 63 from left to right. 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 make the lifter 64 rise or fall. Telescopic rods 66 are installed on the front and back sides of the left side wall of the lifter 64, and a protective film release assembly 67 is installed at 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.

[0041] As a preferred solution, further, the limiting assembly 62 includes a top plate 621 installed at 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, and the protective film is bent and shaped. The outer wall of the limiting column 622 is installed with several steel rings 624 of equal height from top to bottom, and the outer wall of the steel ring 624 is provided with a socket 625.

[0042] As a preferred solution, further, the limiting column 622 is in a stepped shape, 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.

[0043] More specifically, when the protective film release assembly 67 releases the protective film, the protective film passes through the insertion hole 625 of the steel ring 624 via the hollow plate 676 and surrounds the limiting column 622 to form a ring structure; at this time:

[0044] Heating and shaping: The heating rod 623 heats the limiting column 622, and the high temperature is transmitted to the surface of the limiting column 622, so that the protective film in contact is softened by heat, bent and shaped into a circle in the annular gap, thereby preventing the protective film from rebounding and deforming.

[0045] Diameter adaptation: The height of the protective film release component 67 is adjusted by the rotating component 63 so that the plastic coil 674 corresponds to the steel rings 624 of different heights; for example, when a large-diameter tape needs to be packaged, the protective film release component 67 is lifted to allow the protective film to pass through the bottom steel ring, and the larger gap between it and the limiting column 622 is used to form a large-diameter circular protective film; otherwise, the top steel ring is selected to form a small-diameter protective film.

[0046] Precise guidance: The insertion hole 625 of the steel ring 624 provides a fixed threading path for the protective film, ensuring that the protective film is stable in position when it surrounds the limiting column 622, avoiding deviation or wrinkles, and improving the coating accuracy.

[0047] As a preferred embodiment, further, the rotating assembly 63 includes a damping pause knob 631 installed on the right end of the upper surface of the mounting plate 61, and a coaxially rotating drum 632 is installed at the bottom end of the damping pause knob 631. A guide groove 633 is provided on the outer wall of the drum 632, and a pin 65 is inserted into the inner cavity of the guide groove 633.

[0048] As a preferred solution, further, the guide groove 633 is distributed in a stepped manner on the outer wall of the drum 632, and is inclined between the two gradients. When the drum 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 release component 67 switches its position.

[0049] More specifically, when the height of the protective film release assembly 67 needs to be adjusted to accommodate tapes of different sizes, the operating steps are as follows:

[0050] According to the diameter of the tape, the damping pause knob 631 is manually rotated to drive the rotating drum 632 to rotate so that the target step 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, and the telescopic rod 66 and the protective film release assembly 67 are driven to rise and fall synchronously through the elevator 64 until the plastic coil 674 corresponds to the steel ring 624 of the target height in the limit assembly 62 (for example, a large-diameter tape corresponds to the bottom steel ring, and a small-diameter tape corresponds to the top steel ring); when the pin 65 reaches the target step section, the internal damping structure (such as the friction plate) of the damping pause knob 631 provides resistance to keep the rotating drum 632 stationary, ensuring that the protective film release assembly 67 is stable at the target height.

[0051] As a preferred solution, further, the protective film release assembly 67 includes a box body 671 installed at the left end of the telescopic rod 66, a second motor 672 is installed at the center of the bottom of the box body 671, a rotating column 673 is installed at the output end of the second motor 672, and a plastic coil 674 is installed on the outer wall of the rotating column 673. The rotating column 673 is driven by the second motor 672 to drive the plastic coil 674 to rotate, so that the plastic coil 674 releases the protective film, and a positioning column 675 is installed horizontally at the center of the left side wall of the box body 671. The positioning column 675 determines the position of the box body 671 and the positioning column 675. The spacing between the steel rings 624, the left side of the upper surface of the positioning column 675 is an inclined surface. When the box body 671 rises, the positioning column 675 can automatically move to the right under the action of its own inclined surface to avoid inhibiting the rise of the box body 671. A hollow plate 676 corresponding to the position of the socket 625 is installed at the rear end of the left side wall of the box body 671, so that the protective film can pass through the inner cavity of the hollow plate 676 and the socket 625 in turn. A cylinder 677 is installed on the front of the hollow plate 676, and a cutter 678 is installed at the output end of the cylinder 677. The cylinder 677 drives the cutter 678 to move backward, allowing the cutter 678 to cut the protective film.

[0052] More specifically, the second motor 672 drives the rotating column 673 to rotate, and the plastic coil 674 rotates with the rotating column 673 and releases the protective film. After being guided by the inside of the box body 671, the protective film passes through the outlet of the hollow plate 676, enters the socket 625 of the steel ring 624, and surrounds the limiting column 622 to form a ring; when the rotating component 63 drives the box body 671 to rise or fall, the inclined surface of the positioning column 675 contacts the steel ring 624, and unobstructed displacement is achieved through the inclined surface guidance, ensuring that the box body 671 accurately corresponds to the target steel ring 624 (such as a large-diameter tape corresponds 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, cutting the protective film in the hollow plate 676. The cut protective film falls due to gravity and is wrapped around the outside of the tape, completing the wrapping action.

[0053] Working principle:

[0054] Step 1: The first motor 512 drives the screw 513 to rotate clockwise or counterclockwise. The rotational force of the screw 513 drives the push plate 514 to move leftward or rightward. The inclined surface of the slide 515 squeezes the insertion rod 53 inward or outward. Under the support of the slide 52, the distance between the two slide rails 54 becomes smaller or larger, and the slide rails 54 can load tapes of different sizes.

[0055] Step 2: As the conveyor 2 drives the tape carrier 3 to move from left to right, the tape carrier 3 is inserted into the center hole of the tape, pulling the tape to the right, and the baffle 554 is forced to rotate. When the tape falls on the tape carrier 3, the torsion force of the torsion spring 553 drives the baffle 554 to rotate, blocking the next tape, thereby realizing the sequential conveyance of the tapes;

[0056] Step 3: When the tape passes through the protective film release mechanism 6, the second motor 672 drives the rotating column 673 to rotate the plastic coil 674, allowing the plastic coil 674 to release the protective film outward. The protective film is formed into a circular shape by the shape of the gap between the limiting column 622 and the steel ring 624. The heat provided by the heating rod 623 sets the protective film in shape. The cylinder 677 drives the cutter 678 to move backward to cut the protective film. The protective film falls under the action of its own gravity and is wrapped around the outside of the tape, providing packaging material for the tape.

[0057] When the protective film passes through the heater 7, the protective film shrinks due to the heat, so that the protective film shrinks tightly on the surface of the tape, thereby packaging the tape;

[0058] Step 4. When it is necessary to package tapes of different sizes, the damping pause knob 631 is used to drive the rotating drum 632 to rotate clockwise or counterclockwise, so that the rotational force of the guide groove 633 squeezes the pin 65 to descend or ascend. Under the action of the inclined surface of the positioning column 675, the box body 671 can descend or ascend, so that the plastic coil 674 can correspond to the steel ring 624 at different positions to produce circular protective films of different diameters. Therefore, through the cooperation of the feeding mechanism 5 and the protective film release mechanism 6, the packaging task of tapes of different sizes can be completed.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
