Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically to a low-noise active tape dispenser. Background Technology

[0002] Wet kraft paper tape cutting equipment is widely used in the packaging and sealing industry. Its main functions include outputting and cutting tape to a set length to meet different packaging needs. Currently, traditional wet kraft paper tape cutting machines on the market mainly use electromagnets to drive the tape output. However, this traditional technology has the following shortcomings and technical bottlenecks:

[0003] 1) Noise problem

[0004] Electromagnetic drive generates significant mechanical impact noise during the energization and release process. Especially at high frequencies, the noise can reach 87dB, exceeding the noise limit of international standard desktop equipment. This not only affects the operator's working environment but also limits the use of the equipment in offices and quiet places.

[0005] 2) Unstable length output problem

[0006] The electromagnet-driven attraction force is highly sensitive to voltage fluctuations. When the voltage is unstable, insufficient electromagnet force can cause slippage of the conveyor rollers, affecting the stability of the conveyor belt output length. Especially in high-precision applications, this problem can lead to frequent adjustments or rework, reducing the equipment's usability.

[0007] 3) Inconvenient maintenance issues

[0008] In existing technologies, when equipment experiences tape length deviations, it is typically necessary to disassemble the machine and manually fine-tune the mechanical parts. This process is cumbersome and time-consuming, increasing equipment maintenance costs and placing high demands on the technical skills of operators, thus limiting the promotion and widespread adoption of the equipment.

[0009] For example, patent (CN214059450U) discloses an automatic wet tape machine with higher cutting accuracy, but there are some problems in its use. The second reciprocating part 51 is connected to one end of the rotating part 52. The upper guide wheel 21 and the lower guide wheel 22 are engaged and disengaged by the rise or fall of the output end of the second reciprocating part 51. The second reciprocating part 51 in this patent is an electromagnet, which has the problems of high noise and easy slippage of the upper guide wheel 21 and the lower guide wheel 22, resulting in poor tape output stability.

[0010] In view of the technical shortcomings of the above-mentioned patents, it is necessary to upgrade and improve the structure. Utility Model Content

[0011] The purpose of this utility model is to provide a low-noise active tape dispenser in order to solve the above-mentioned technical problems.

[0012] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0013] A low-noise active tape dispenser includes a dispenser body, which includes a housing and a drive.

[0014] The drive includes a mounting bracket, a motor, a steering gear, and a support bearing. The mounting bracket is screwed to the bottom of the housing. The motor output shaft is connected to the steering gear. The steering gear is fixedly mounted on the side wall of the mounting bracket. The output end of the steering gear is eccentrically fixedly connected to a round wheel. The inner ring of the support bearing is fixedly connected to the round wheel by bolts.

[0015] The motor can be either a brushless or brushed motor.

[0016] The outer ring of the support bearing extends beyond the edge of the wheel, so that when the outer ring of the support bearing contacts the bottom of the linkage plate, the wheel and the linkage plate are prevented from contacting each other. The linkage plate in this utility model is the rotating component in the prior art. The two have the same function. The connection relationship between the linkage plate, the upper guide wheel and the lower guide wheel is the prior art. The upper guide wheel and the lower guide wheel can be engaged and disengaged by rotating the linkage plate.

[0017] In use, when the support bearing rotates clockwise upwards, it drives the linkage plate to rotate clockwise, causing the upper guide wheel and the lower guide wheel to engage; when the support bearing rotates counterclockwise downwards, the upper guide wheel and the lower guide wheel separate.

[0018] The motor is inclined to the bottom of the housing. This inclined arrangement reduces the overall height and, moreover, the motor, steering gear, and mounting bracket form a triangular structure that enhances drive stability.

[0019] The distributor body also includes a heating device, which includes a heating cover, a base plate, a counterweight, and heating elements.

[0020] A counterweight is fixed inside the heating cover, and the heating element is glued to the bottom of the base plate. The base plate is fixed to the heating cover.

[0021] The base plate has a hook on the left side, and side plates on the front and rear sides, with slots at the front end of the side plates. The side plates and the base plate are integrally formed.

[0022] In existing technology, during paper output, the tape is conveyed to the output board via upper and lower guide rollers. The output board is rotatably connected to the box body via a rotating shaft. A heating device is located on the output board to heat the tape. Clips are located on both sides of the output board, which are used in conjunction with the heating device. In use, the slots are engaged with the clips. When the slots and clips are fully engaged, the hooks are positioned on one side of the rotating shaft, creating a limiting effect. The slot design allows for quick disassembly of the heating device, facilitating the timely cleaning of accumulated paper scraps.

[0023] In existing technologies, a tightening bolt is installed above the heating device to maintain the working pressure between the brush and the adhesive tape. Pressure is adjusted manually by tightening the bolt. However, this invention replaces the manual pressure adjustment method with a counterweight, ensuring that the brush always maintains optimal working pressure. In use, one part of the base plate is located above the output paper, and the other part of the base plate is in contact with the brush.

[0024] The side plate has screw holes and a square notch. The screw holes are used to connect and fix bolts. In use, one end of the fixing bolt passes through the limiting groove on the cardboard, and the square notch engages with the protrusion on the cardboard. The limiting groove and square notch limit the side plate. In use, first, the slot is inserted into the retaining shaft, and then the base plate is rotated so that the fixing bolt is turned into the limiting groove and the protrusion engages with the square notch.

[0025] The distributor body also includes a water outlet tank, and the water outlet of the water outlet tank is equipped with an automatic water outlet device, which consists of a water outlet cover, a sealing sleeve and a spring.

[0026] The water outlet cover is fixedly connected to the water outlet by threads, and has a through hole inside that connects the upper water outlet groove and the lower water outlet groove;

[0027] The movable rod is installed on the top of the water outlet cover, and the top is equipped with a sealing sleeve. The lower part of the movable rod is connected to a spring, and the other end of the spring is fixed to the top of the water outlet cover.

[0028] In use, the water tank is installed upside down on one side of the distributor, with the water outlet cap facing down and aligned with the water storage box. The water storage box is located directly below the water tank, and its interior is equipped with a brush to moisten the adhesive side of the tape. A fixing pin is located on the right side of the water storage box, aligned with the water outlet, to support and align the water flow path.

[0029] Initially, the sealing sleeve is in the open position of the upper water outlet groove under the action of the spring, allowing water to enter the water storage box through the upper and lower water outlet grooves. The water outlet tank is connected to the outside through the top opening, allowing air to enter the water tank and maintain the water output process. When the water level in the water storage box gradually rises and touches the water outlet cover, the water seals the opening, preventing air from entering the water tank. At this time, a negative pressure (vacuum state) is formed in the water outlet tank, the water flow stops, and the water level in the water storage box remains unchanged.

[0030] When the brush absorbs water or the water in the storage box is consumed, the water level drops, the pores are exposed to air again, air re-enters the water tank, the negative pressure is released, and the water flow resumes into the storage box, maintaining dynamic balance.

[0031] In this invention, the upper and lower guide wheels are engaged and disengaged by setting a drive mechanism, and an electric motor is used as the power source to replace the traditional electromagnet, eliminating the problem of high decibel noise and reducing the operating noise of the equipment to meet international standards.

[0032] By combining a motor and a wheel, a smooth and controllable power output can be provided, avoiding the problems of insufficient or inconsistent attraction caused by voltage fluctuations in traditional electromagnets. At the same time, the transmission system of the equipment adopts a high-precision design to ensure the stability and consistency of power transmission when conveying the belt, thereby significantly improving the accuracy of the output belt length and reducing length deviations caused by slippage of the conveyor wheel or insufficient power.

[0033] This invention also incorporates a program-controlled parameter setting module. When the tape length deviates, the user can access the parameter adjustment interface via the control panel without disassembling the equipment to fine-tune the lifting angle of the cutter drive motor, ensuring the equipment quickly returns to its optimal working state. Compared to traditional equipment that requires disassembly and adjustment of the mechanical structure, this solution significantly reduces maintenance complexity and improves ease of use and work efficiency.

[0034] The beneficial effects of this utility model are as follows:

[0035] This invention solves the problems of high noise and unstable power in traditional electromagnet drive devices by innovatively combining a motor and a wheel; and improves the maintainability and reliability of the equipment by designing a quick-release heating device.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figures 1 to 7 As shown, this embodiment provides a low-noise active tape dispenser, including a dispenser body 1, which includes a housing 2 and a drive.

[0048] The drive includes a mounting bracket 3, a motor 4, a steering gear 5, and a support bearing 6. The mounting bracket 3 is screwed to the bottom of the housing 2. The output shaft of the motor 4 is connected to the steering gear 5. The steering gear 5 is fixedly installed on the side wall of the mounting bracket 3. The output end of the steering gear 5 is eccentrically fixedly connected to the wheel 7. The inner ring of the support bearing 6 is fixedly connected to the wheel 7 by bolts.

[0049] Motor 4 is either a brushless or brushed motor.

[0050] The outer ring of the support bearing 6 extends beyond the edge of the wheel 7, so that when the outer ring of the support bearing 6 contacts the bottom of the linkage plate 8, the wheel 7 avoids contact with the linkage plate 8. The linkage plate 8 in this utility model is the rotating component in the prior art. The two have the same function. The connection relationship between the linkage plate 8, the upper guide wheel 9 and the lower guide wheel 10 is the prior art. The upper guide wheel 9 and the lower guide wheel 10 can be engaged and disengaged by rotating the linkage plate 8.

[0051] In use, when the support bearing 6 rotates clockwise upward, it drives the linkage plate 8 to rotate clockwise, causing the upper guide wheel 9 and the lower guide wheel 10 to engage; when the support bearing 6 rotates counterclockwise downward, the upper guide wheel 9 and the lower guide wheel 10 separate.

[0052] The motor 4 is inclined to the bottom of the housing 2. The inclined arrangement of the motor 4 can reduce the height, and the triangular structure formed by the motor 4, the steering gear 5, and the mounting bracket 3 makes the drive more stable.

[0053] The distributor body 1 also includes a heating device, which includes a heating cover 11, a base plate 12, a counterweight 14 and a heating element 13;

[0054] A counterweight 14 is fixedly connected inside the heating cover 11, the heating element 13 is bonded to the bottom of the base plate 12, and the base plate 12 is fixedly connected to the heating cover 11.

[0055] The base plate 12 has a hook 15 on the left side, and side plates 16 on both the front and rear sides of the base plate 12. The front end of the side plate 16 has a slot 17. The side plate 16 and the base plate 12 are integrally formed.

[0056] In the existing technology, during paper output, the tape is conveyed to the output sheet 20 via the upper guide roller 9 and the lower guide roller 10. The output sheet 20 is rotatably connected to the housing 2 via a rotating shaft. A heating device is installed on the output sheet 20 to heat the tape. The output sheet 20 has locking shafts 23 on both sides, which are used in conjunction with the heating device. In use, the slot 17 engages with the locking shaft 23. When the slot 17 and locking shaft 23 are engaged, the hook 15 is positioned on one side of the rotating shaft, forming a limit. The slot 17 design allows for quick disassembly of the heating device, facilitating timely cleaning of accumulated paper scraps.

[0057] In existing technologies, a tightening bolt is installed above the heating device to maintain the working pressure between the brush and the adhesive tape. Pressure is adjusted manually by tightening the bolt. This invention, however, replaces this manual pressure adjustment method with a counterweight 14, ensuring the brush always maintains optimal working pressure. During use, part of the base plate 12 is positioned above the output board 20, and the other part of the base plate 12 contacts the brush 35. The water-soluble adhesive layer of the tape requires an appropriate amount of water to activate its adhesiveness. To ensure the tape's flexibility in low-temperature or humid environments and to further improve the tape's adhesion after wetting, a heating plate 20 is installed above the output board. The gap between the base plate 12 and the output board 20 allows the tape to pass through. The heating element 13 heats the base plate 12, maintaining the tape at a suitable temperature and ensuring its flexibility and ease of handling.

[0058] The side plate 16 is provided with screw holes 18 and square notches 19. The screw holes 18 are used to connect the fixing bolts 34. In use, one end of the fixing bolts 34 passes through the limiting groove 21 on the cardboard 20. The square notches 19 and the protrusions 22 on the cardboard 20 are engaged and connected. The limiting grooves 21 and square notches 19 limit the side plate 16. In use, the slot 17 is first engaged with the retaining shaft 23, and then the base plate 12 is rotated so that the fixing bolts 34 are turned into the limiting grooves 21 and the protrusions 22 are engaged into the square notches.

[0059] The distributor body 1 also includes a water outlet tank 24. The water outlet of the water outlet tank 24 is equipped with an automatic water outlet device. The automatic water outlet device includes a water outlet cover 25, a sealing sleeve 26, and a spring 27. The inner wall of the water outlet cover 25 is threaded. The middle part of the water outlet cover 25 protrudes upward and forms an upper water outlet groove 28 and a lower water outlet groove 29. The upper water outlet groove 28 and the lower water outlet groove 29 are connected by a through hole 30. A movable rod 31 is sleeved on the top of the water outlet cover 25. The sealing sleeve 26 is provided on the top of the movable rod 31. The spring 27 is sleeved on the lower part of the movable rod 31. The lower end of the spring 27 is fixedly connected to the movable rod 31, and the upper end of the spring 27 is fixedly connected to the water outlet cover 25. The water outlet cover 25 is fixed to the water outlet via a threaded connection. In use, the water tank 24 is installed on one side of the distributor, with the water outlet cover 25 facing downwards so that the movable rod 31 contacts the ejector pin 33. Under the action of the spring 27, the movable rod 31 moves upwards, causing the sealing sleeve 26 to leave the upper water outlet groove 28 and begin water flow. Water flows through the upper water outlet groove 28 into the lower water outlet groove 29 and into the water storage box on the distributor. When the water level in the storage box contacts the water outlet cover 25, the water outlet cover 25 stops discharging water. In the prior art, the sealing plate is located at the bottom of the water outlet cover 25, and the ejector pin 33 lifts the sealing plate to allow water to flow. However, the sealing plate is prone to deformation and has poor sealing performance. The sealing sleeve 26 of this invention avoids direct contact between the sealing sleeve 26 and the ejector pin 33, resulting in a longer service life and better sealing performance.

[0060] The distributor body 1 also includes a water outlet tank 24, and the water outlet of the water outlet tank 24 is equipped with an automatic water outlet device, which consists of a water outlet cover 25, a sealing sleeve 26 and a spring 27.

[0061] The water outlet cover 25 is fixedly connected to the water outlet by threads, and has a through hole 30 inside that connects the upper water outlet groove 28 and the lower water outlet groove 29;

[0062] The movable rod 31 is installed on the top of the water outlet cover 25, and the top is equipped with a sealing sleeve 26. The lower part of the movable rod 31 is connected to the spring 27, and the other end of the spring 27 is fixed to the top of the water outlet cover 25.

[0063] In use, the water tank 24 is installed upside down on one side of the distributor, with the water outlet cap 25 facing downwards and aligned with the water storage box 35. The water storage box 35 is located directly below the water tank 24, and a brush 32 is installed inside to moisten the adhesive side of the tape. A fixing pin 33 is installed on the right side of the water storage box 35, which is aligned with the water outlet to support and align the water outlet path.

[0064] Initially, the sealing sleeve 26 is in the open position of the upper water outlet 28 under the action of the spring 27, allowing water to enter the water storage box 35 through the upper and lower water outlets 29. The water outlet tank 24 is connected to the outside through the top through hole 30, allowing air to enter the water tank and maintain the water output process. When the water level in the water storage box 35 gradually rises and contacts the water outlet cover 25, the water seals the through hole 30, preventing air from entering the water tank. At this time, a negative pressure (vacuum state) is formed in the water outlet tank 24, the water flow stops, and the water level in the water storage box 35 remains unchanged.

[0065] When the brush 32 absorbs water or the water in the water storage box 35 is consumed, the water level drops, the air vent is exposed to the air again, the air re-enters the water tank, the negative pressure is released, and the water flow resumes into the water storage box 35, maintaining dynamic balance.

[0066] In this utility model, the upper guide wheel 9 and the lower guide wheel 10 are engaged and disengaged by setting a drive, and a motor 4 is used as the power source to replace the traditional electromagnet, eliminating the problem of high decibel noise and reducing the operating noise of the equipment to meet international standards.

[0067] The combination of motor 4 and wheel 7 provides a stable and controllable power output, avoiding the problems of insufficient or inconsistent attraction caused by voltage fluctuations in traditional electromagnets. Simultaneously, the equipment's transmission system employs a high-precision design to ensure the stability and consistency of power transmission during belt conveying, thereby significantly improving the accuracy of the output belt length and reducing length deviations caused by conveyor wheel slippage or insufficient power.

[0068] This invention also incorporates a program-controlled parameter setting module. When the tape length deviates, the user can access the parameter adjustment interface via the control panel without disassembling the equipment to fine-tune the lifting angle of the cutter drive motor 4, ensuring the equipment quickly returns to its optimal working state. Compared to traditional equipment that requires disassembly and adjustment of the mechanical structure, this solution significantly reduces maintenance complexity and improves ease of use and work efficiency.
