Description

Technical Field

[0001] The invention relates to the field of carton sealing machines, and in particular to an alignment device for carton sealing tapes. Background Art

[0002] In the packaging industry, wrapping sealing machines are widely used for sealing and reinforcing cartons. They wrap tape around the carton in one or more circles to ensure that the carton is not easily deformed or damaged during transportation.

[0003] However, in actual use, there are still some problems with wrapping carton sealers, which affect the consistency and aesthetics of the sealing effect. First, when the operator manually operates the wrapping carton sealer, due to the instability of the hand movement, the winding angle of the tape is easily changed, sometimes to the left, sometimes to the right, and it is difficult to achieve a neat alignment effect. This inconsistent winding method not only affects the aesthetics of the sealing, but also may reduce the sealing effect of the tape, causing the carton to loosen or break easily during transportation; secondly, when winding multiple layers of tape, since the starting position and winding path of each layer of tape are difficult to be completely consistent, it is easy to have the problem of tape misalignment between layers. This misalignment not only affects the appearance of the sealing, but may also cause uneven force on the tape, thereby affecting the overall strength of the carton.

[0004] Based on the above situation, the present invention proposes an alignment device for sealing tape. Summary of the invention

[0005] In order to overcome the shortcomings of existing carton sealing machines, such as unstable manual operation leading to tape deviation and multi-layer winding misalignment, which affects the aesthetics and sealing performance, the technical problem of the present invention is to provide an alignment device for sealing tape.

[0007] More preferably, the limiting member is provided with evenly distributed oblique bayonet openings, the width of the oblique bayonet openings is equal to the width of the tape, and the sliding rod is squeezed and matched with the limiting member, so as to control the distance of each backward movement of the carton to be consistent when the carton is wound in multiple layers.

[0011] More preferably, the device installation box is provided with a first guide rail on one side close to the first screw rod and the second screw rod, and the centering piece slides on the adjacent first guide rail, so as to guide the centering piece when it moves inward and outward.

[0012] More preferably, the symmetrically distributed transmission components are composed of two transmission wheels and a flat belt, the first screw and the second screw are fixedly connected with symmetrically distributed transmission wheels, and the flat belt is wound around the two transmission wheels in the longitudinal direction.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Refer to the attached Figure 1-3 A device for aligning sealing tape includes a winding sealing machine 1. The winding sealing machine 1 mainly includes an equipment installation box, a tape supply system, a winding mechanism, an operating handle, a tape cutting device, a frame and other parts. A space cavity for installing equipment is opened in the equipment installation box. A push plate 11 and a positioning plate 12 are slidably connected to the equipment installation box. The push plate 11 and the positioning plate 12 are arranged opposite to each other relative to the winding mechanism. The push plate 11 and the positioning plate 12 block the carton to be sealed from the front and back sides, so that the carton enters the winding mechanism in a straight line.

[0027] During the carton sealing process, the tape is installed on the tape supply system to ensure that the tape can be smoothly transported. The carton is placed on the upper surface of the equipment installation box, and the front side of the carton is in contact with the push plate 11. Space is left on the back side of the carton so that the carton can be pushed into the winding mechanism later. The push plate 11 is pushed backward to drive the carton to move backward in a straight line until the rear wall of the carton contacts the positioning plate 12. The push plate 11 and the positioning plate 12 clamp the carton from the front and back sides to ensure that the carton maintains vertical and linear movement when entering the winding mechanism;

[0028] After the carton enters the wrapping mechanism, the staff needs to hold the carton to prevent it from shifting due to the tension of the tape during the wrapping process. The staff controls the wrapping mechanism to start working by operating the handle. The tape supply system delivers the tape to the wrapping mechanism, and the wrapping mechanism wraps the tape evenly around the interface of the carton. After the tape wraps around the carton once, the operating handle controls the wrapping mechanism to stop working, and the tape cutting device starts to cut the tape, completing a carton sealing operation.

[0029] If multiple turns of tape need to be wrapped, the push plate 11 can be continued to be pushed to move the carton and the positioning plate 12 backward together until the carton reaches the next wrapping position, and the above wrapping and cutting process is repeated until the required carton sealing operation is completed. After the carton sealing is completed, the carton is taken out of the wrapping mechanism and prepared for the next carton sealing operation.

[0030] As described in the background technology, when wrapping a carton with multiple layers, it is difficult for the starting position and winding path of each layer of tape to be completely consistent, which can easily lead to misalignment of the tape between layers, affecting the sealing effect and aesthetics. Therefore, in this embodiment, when wrapping the carton, it is necessary to control the distance of each backward movement.

[0031] Specifically, a sliding rod 13 is slidably connected to the positioning plate 12, and a symmetrically distributed first spring 14 is connected between the sliding rod 13 and the positioning plate 12. The symmetrically distributed first springs 14 are all wound around the sliding rod 13. A symmetrically distributed limiting member 15 is provided on the side close to the positioning plate 12 in the equipment installation box. The limiting member 15 is provided with evenly distributed oblique bayonet slots, and the width of the oblique bayonet slots is equal to the width of the tape. Through extrusion fitting, it is ensured that the sliding rod 13 can be accurately inserted into the oblique bayonet slots.

[0032] As mentioned above, place the carton on the rear side of the push plate 11, push the push plate 11 to make the carton enter the winding mechanism, and control the winding mechanism through the operating handle to perform the first circle of tape winding. After the winding is completed, the tape cutting device cuts the tape and continues to push the push plate 11 backward, driving the carton and the positioning plate 12 to move backward. During the backward movement of the positioning plate 12, the sliding rod 13 moves backward along the inclined surface on the limiting member 15. During the backward movement of the sliding rod 13, the first spring 14 is deformed first and then reset. When the sliding rod 13 moves to the first oblique bayonet, stop pushing the push plate 11, and the sliding rod 13 is stuck in the bayonet. At this time, the distance the carton moves backward is equal to the width of the tape.

[0033] Perform the second circle of winding according to the above steps, ensuring that the starting position is aligned with the first circle, and continue winding in this way. For each circle of winding, the carton moves backward a distance of the tape width. When the carton length is not a natural number multiple of the tape width, there may be a little blank space left after winding several circles. Continue to push the push plate 11 until it reaches the end of the slide slot, and the carton will also move backward a short distance. Correspondingly, the sliding rod 13 moves backward a short distance along the inclined surface to ensure that the last circle of tape can cover the penultimate circle of tape and cover the remaining blank space. The carton has completed multi-layer winding, and the starting positions of all tape layers are aligned. The last circle of tape covers the entire area without any blank space. The staff takes the carton off the table and prepares for the next carton sealing operation.

[0034] The last bayonet on the limiting member 15 is horizontal. When the length of the carton to be wound reaches the maximum value, which is equal to the distance between the push plate 11 and the positioning plate 12, the carton has completed the first few turns of winding, and the distance of each backward movement is equal to the width of the tape. The push plate 11 is pushed backward continuously, driving the carton, the positioning plate 12 and the sliding rod 13 to move backward together. The sliding rod 13 moves backward along the inclined surface of the limiting member 15 until it reaches the last horizontal bayonet. Since the last bayonet is horizontal, the sliding rod 13 will be accurately blocked by the horizontal bayonet and cannot continue to move backward, thereby preventing the carton from moving backward excessively.

[0035] While the sliding rod 13 is blocked by the horizontal bayonet, the push plate 11 also moves backward to the end of the slide slot to reach the maximum moving distance. Since the sliding rod 13 is blocked by the horizontal bayonet, the position of the carton is accurately fixed, ensuring that the starting position of the last circle of tape is aligned with the previous circle. The winding mechanism is controlled by the operating handle to wind the last circle of tape. After the winding is completed, the tape cutting device cuts the tape to complete the box sealing operation.

[0036] The carton has been sealed, and the sliding rod 13 is blocked by the horizontal snap-in of the limiting member 15 and cannot move forward to reset. The push plate 11 is located at the end of the slide slot, the positioning plate 12 and the sliding rod 13 are at the rearmost position, and the oblique snap-in of the limiting member 15 is set backward to prevent the sliding rod 13 from moving from the back to the front. In this embodiment, in order to solve the problem that the sliding rod 13 is stuck by the limiting member 15 when resetting from the back to the front, a reset mechanism is designed.

[0037] Reference Figure 2 Specifically, the reset mechanism includes an electric slide rail 16 installed in the equipment installation box, and a sliding member 17 is slidably connected to the electric slide rail 16 for pushing the positioning plate 12 back to its original position. Release members 18 are symmetrically distributed and slidably connected along the electric slide rail 16 in the equipment installation box for controlling the inward and outward movement of the limiting member 15. The symmetrically distributed release members 18 are provided with inclined surfaces on the side close to the sliding member 17. Second springs 19 are connected between the symmetrically distributed release members 18 and the inner wall of the equipment installation box. The symmetrically distributed second springs 19 are all wound around the adjacent release members 18, and the limiting member 15 and the adjacent release members 18 are fixedly connected.

[0038] When a carton is sealed, the electric slide rail 16 is controlled to drive the sliding member 17 to move forward. When the sliding member 17 moves forward, it squeezes the inclined surface on the release member 18. Due to the effect of the inclined surface, the release member 18 separates outward, driving the limiting member 15 to move outward. After the limiting member 15 moves outward, it no longer blocks the sliding rod 13. The second spring 19 is deformed when the release member 18 moves outward, storing elastic potential energy. The sliding member 17 continues to move forward and contacts the positioning plate 12. The sliding member 17 pushes the positioning plate 12 to move forward and return to the initial position.

[0039] The sliding rod 13 also moves forward and resets, and the positioning plate 12 that moves forward pushes the sealed carton back to the front for the staff to take out. The push plate 11 moves forward together with the positioning plate 12 and returns to the starting end of the slide slot. At this time, the sliding rod 13, the positioning plate 12 and the push plate 11 all return to their initial positions. Then, the electric slide rail 16 is controlled to drive the sliding member 17 to move backward and reset. The sliding member 17 no longer squeezes the releasing member 18. The releasing member 18 resets under the elastic action of the second spring 19, and the limiting member 15 returns to the working position again, ready for the next carton sealing operation.

[0040] In this embodiment, the carton is moved backward in a straight line by pushing the push plate 11, so that the carton is placed vertically relative to the winding mechanism, and the wound tape is perpendicular to the carton; the oblique snap-in on the limiting member 15 cooperates with the sliding rod 13 to ensure that the distance the carton moves backward each time is equal to the width of the tape, so that the starting position of each layer of tape and the winding path are completely consistent, avoiding misalignment of the tape and improving the aesthetics and sealing effect of the carton sealing; the horizontal snap-in on the limiting member 15 ensures that the carton is accurately fixed during the last round of winding to avoid excessive backward movement; through the coordinated work of the electric slide rail 16, the sliding member 17, the release member 18 and the second spring 19, the automatic resetting of the sliding rod 13, the positioning plate 12 and the push plate 11 is realized without manual intervention, thereby improving efficiency.

[0041] Reference Figure 4 As mentioned above, during the sealing process, each time the tape is wound, the carton needs to be held down to prevent it from shifting due to the tension of the tape during the winding process. This operation not only increases the labor intensity of the staff, but also reduces the work efficiency. This problem is particularly prominent in the scenario of mass sealing. Therefore, this embodiment needs to automatically stabilize the carton during the sealing process to prevent it from shifting.

[0042] Specifically, the device installation box is provided with a motor 2, and a first screw 21 and a second screw 25 are symmetrically rotatably connected along a winding mechanism inside the device installation box. The motor 2 is connected to the first screw 21 through a coupling, and a symmetrically distributed transmission component 24 is connected between the first screw 21 and the second screw 25 for transmitting power. The first screw 21 and the second screw 25 are both threadedly connected with symmetrically distributed centering pieces 22. The device installation box is provided with a first guide rail 23 on one side close to the first screw 21 and the second screw 25, and the centering piece 22 slides on the adjacent first guide rail 23.

[0043] The symmetrically distributed transmission components 24 are composed of two transmission wheels and a flat belt. The first screw rod 21 and the second screw rod 25 are fixedly connected with symmetrically distributed transmission wheels, and the flat belt is wound around the two transmission wheels in the longitudinal direction.

[0044] After the carton is placed against the push plate 11, the control motor 2 drives the first screw 21 to rotate, thereby rotating the second screw 25 through the transmission assembly 24, and driving the centering piece 22 to move toward the carton at the same time. The centering piece 22 will apply a force toward the center to the carton to center the carton. The centering piece 22 will clamp the two sides of the carton. The carton is limited and will not be offset due to the tension of the tape. The push plate 11 can be pushed according to the above steps to make the carton enter the winding mechanism and evenly wind the tape on the carton. After the winding is completed, and the positioning plate 12 pushes the sealed carton from the back to the front, the motor 2 drives the first screw 21 and the second screw 25 to rotate in the opposite direction, driving the centering piece 22 to release the carton.

[0045] This embodiment automatically clamps the carton through the coordinated work of the motor 2, the first screw 21, the centering piece 22, the first guide rail 23, the transmission assembly 24 and the second screw 25, thereby solving the problem of manually holding down the carton during the carton sealing process and achieving automatic fixation and stable winding of the carton, which not only improves the carton sealing efficiency but also reduces labor costs and has high practical value.

[0046] Example 2: When the weight of the sealed carton is large, placing it directly on the equipment installation box will cause large friction and make it difficult to adjust the position; and after the sealing is completed, it is difficult for the staff to extend their fingers to the bottom of the carton to carry it. Therefore, when sealing a heavy carton, this embodiment needs to lift the carton upwards to facilitate position adjustment and transportation.

[0047] Reference Figure 5-6 Specifically, the device installation box is fixed with symmetrically distributed second guide rails 31, and the symmetrically distributed second guide rails 31 are all slidably connected with first racks 3. Third springs 32 are connected between the symmetrically distributed first racks 3 and the inner wall of the device installation box. The symmetrically distributed third springs 32 are all wound around the adjacent second guide rails 31. The third springs 32 are always in a deformed state, and the centering member 22 is in contact with the adjacent first rack 3. The winding carton sealing machine 1 is provided with symmetrically distributed lifting members 35, and the symmetrically distributed lifting members 35 are all provided with second racks 34. The device installation box is provided with symmetrically distributed gear sets 33;

[0048] The gear set 33 is composed of two gears, one small gear is located on the inside and the other large gear is located on the outside. The first rack 3 meshes with the small gear on the inside, and the large gear on the outside meshes with the second rack 34 to form a gear transmission system. When the first rack 3 moves outward or inward, it drives the small gear on the inside to rotate, and the small gear drives the large gear on the outside to rotate. The rotation of the large gear drives the second rack 34 to move. Since the diameter of the large gear is larger than that of the small gear, the moving distance of the lifting member 35 is larger than that of the first rack 3. Through the gear transmission system, the first rack 3 only needs to move a shorter distance to achieve a larger moving distance of the lifting member 35, saving the internal space of the device installation box.

[0049] Initially, the lifting member 35 is extended from the equipment installation box. The staff places a heavier carton on the lifting member 35 and adjusts its position to make it close to the push plate 11. As mentioned above, when the centering member 22 moves inward to clamp the carton, under the elastic force of the third spring 32, the first rack 3 will move inward and drive the lifting member 35 downward through the gear set 33 and the second rack 34. The lifting member 35 will sink into the equipment installation box, and the carton will contact the upper surface of the equipment installation box to ensure that the carton remains stable during the winding process.

[0050] After the carton is sealed, the centering piece 22 moves outward to loosen the carton. The outward moving centering piece 22 will push the first rack 3 to move outward, thereby driving the lifting piece 35 to move upward through the gear set 33 and the second rack 34. The lifting piece 35 will push the carton upward, leaving a certain space between the carton and the upper surface of the equipment installation box. The staff can easily insert their fingers into the bottom of the carton and lift it up.

[0051] This implementation solves the problem that heavy cartons are difficult to adjust their position and carry during the sealing process by lifting the cartons, and realizes the automatic lifting and lowering of the cartons, which not only improves the sealing efficiency and quality, but also reduces labor costs.

[0052] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
