Description

Technical Field

[0001] This utility model relates to the technical field of foam board production equipment, and in particular to a tape cutting structure for a foam board tape machine. Background Technology

[0002] In the field of automated packaging for products such as foam boards and cardboard boxes, tape wrapping and sealing equipment is one of the core pieces of equipment. The tape cutting device at the end of the tape wrapping device generally uses a cutter assembly driven by a cylinder or motor, which cuts the tape through linear reciprocating or oscillating motion. To address the common problem of tape residue easily adhering to the cutter, existing technologies mainly focus on two aspects for improvement: firstly, improving the blade material, such as using a Teflon non-stick coating to passively reduce adhesive residue adhesion; secondly, relying on operators to periodically stop the machine and manually wipe it clean with solvents.

[0003] However, all of the aforementioned existing technical solutions have significant drawbacks. Teflon coatings will still fail after prolonged use due to wear or adhesive buildup, and they cannot solve the problem of the blade becoming dull due to impurities in the tape and repeated cutting, resulting in uneven cuts. Manual cleaning, on the other hand, directly disrupts continuous production, increases labor costs and maintenance burden, and severely impacts the overall operating efficiency of the production line. Both of these methods are essentially passive or reactive, failing to achieve proactive and fundamental self-cleaning during equipment operation.

[0004] Therefore, in the face of the increasing demand for automated production, there is an urgent need in this field for an online self-cleaning solution integrated into the cutting action. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a tape cutting structure for a foam board tape machine to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides a tape cutting structure for a foam board tape machine, comprising: frame; A cutting unit, which is mounted on the frame, includes a cutter and a drive mechanism that drives the cutter to rotate about its axis. A reciprocating drive mechanism is used to drive the cutting unit to reciprocate feed relative to the frame, so that the rotating cutter cuts into and out of the conveyor path of the conveyor belt to complete the cutting. A scraper cleaning unit includes a scraper whose blade abuts against the working surface of the cutter, for scraping off tape residue from the surface of the cutter; The spray cleaning unit includes a solvent storage tank, a delivery pipeline, and at least one spray head, which is positioned upstream of the contact area between the cutter and the scraper, for spraying solvent onto the rotating cutter surface to dissolve or soften residues and allow them to be scraped off by the scraper.

[0007] As a preferred embodiment of the present invention, the frame includes: a base plate and a support disposed at the upper end of the base plate, wherein the surface of the support is provided with a clearance groove for the output end of the drive mechanism to move.

[0008] As a preferred embodiment of this utility model, the cutting unit includes: The slider has a groove on its surface, and the groove slides in cooperation with the guide rail set on the surface of the bracket; A first motor is fixedly connected to the slider, and the output shaft of the first motor passes through the clearance groove and is connected to the cutter spline.

[0009] As a preferred embodiment of this utility model, the reciprocating drive mechanism includes: One end of the upright is fixedly connected to the base plate; A second motor is installed at the other end of the pole, and the output end of the second motor passes through the pole and is connected to a crank. The rocker arm has one end rotatably connected to the side of the crank away from the output end of the second motor, and the other end rotatably connected to a movable block. The movable block is fixedly connected to the slider, and the lower end of the bracket forms a tape channel.

[0010] As a preferred embodiment of this utility model, the scraping cleaning unit includes: The tool holder is plugged into a tool holder mounting slot on one side of the slider. The tool holder has a slot for inserting a scraper. Both the scraper and the tool holder have threaded grooves. Fastening bolts that pass through the threaded groove connecting the scraper and the blade holder; A knob, which is located on the side of the slider near the tool holder mounting slot, is used to limit the movement of the tool holder relative to the slider.

[0011] As a preferred embodiment of this invention, the surface of the scraper is provided with a strip groove for the sprayed solvent to slide off.

[0012] As a preferred embodiment of this utility model, the spray cleaning unit includes: A piston cylinder is fixedly mounted on the base plate. The surface of the piston cylinder is provided with a liquid outlet and a liquid inlet. Both the liquid outlet and the liquid inlet are provided with a one-way valve. The liquid inlet is connected to a solvent storage tank through a conduit, and the liquid outlet is connected to a spray head through a conduit. A piston, which is slidably disposed within the piston cylinder; A pressure plate is fixedly connected to the slider. One end of the pressure plate is connected to a piston rod, and the other end of the piston rod away from the pressure plate is connected to a piston. The reciprocating motion of the slider relative to the bracket drives the piston to move synchronously in the piston cylinder, so as to extract the solvent in the solvent storage tank and squeeze it into the spray head.

[0013] As a preferred embodiment of this invention, the surface of the slider is provided with an adjustable support frame, which is connected to the spray head to adjust the spray direction of the adjustable support frame.

[0020] like Figure 1 , Figure 2 As shown, a tape cutting structure for a foam board tape machine includes: a frame; a cutting unit mounted on the frame, the cutting unit including a cutter 9 and a drive mechanism for driving the cutter 9 to rotate around its axis; a reciprocating drive mechanism for driving the cutting unit to reciprocate relative to the frame, so that the rotating cutter 9 cuts into and leaves the tape conveying path to complete the cutting; a scraping cleaning unit including a scraper 17 whose blade abuts against the working surface of the cutter 9, for scraping off tape residue from the surface of the cutter 9; and a spray cleaning unit including a solvent storage tank, a conveying pipeline, and at least one spray head 29, the spray head 29 pointing upstream of the contact area between the cutter 9 and the scraper 17, for spraying solvent onto the surface of the rotating cutter 9, so that the residue is dissolved or softened and scraped off by the scraper 17; The above technical solution solves the technical problems of traditional cutters 9 easily adhering to adhesive residue and requiring frequent manual cleaning. Specifically, its working principle and operating steps are as follows: During the sealing operation, when the tape needs to be cut, the reciprocating drive mechanism starts, pushing the entire cutting unit towards the tape conveyor path. Simultaneously, the cutting unit's own drive mechanism drives the cutter 9 to rotate at high speed. The rotating cutter 9 cuts into the tape like a circular saw, completing an efficient cut. After cutting, the reciprocating drive mechanism drives the cutting unit to retract. Throughout the process, the spray nozzle 29 of the spray cleaning unit sprays solvent onto the surface of the rotating cutter 9, pre-dissolving and softening the tape residue; then, the scraper 17, which remains in contact with the surface of the cutter 9, thoroughly scrapes away the softened residue. This achieves simultaneous automation of cutting and cleaning, ensuring the cutter 9 remains continuously clean and sharp, thus ensuring smooth cutting and a flat cut surface, significantly improving the continuous operation efficiency and stability of the equipment.

[0021] like Figure 3 As shown, in this embodiment, the frame includes: a base plate 1, and a bracket 2 disposed at the upper end of the base plate 1. The surface of the bracket 2 is provided with a clearance groove 8 for the output end of the drive mechanism to move. The above technical solution solves the problem of collision between the drive mechanism and the fixed frame on the reciprocating motion trajectory. Specifically, its working principle and operation steps are as follows: The base plate 1 provides a stable mounting foundation for the entire structure, while the bracket 2 serves as the main support for the moving parts. The clearance groove 8 provides the necessary space for the output end of the drive mechanism to move during reciprocating motion, preventing structural interference. This ensures the smoothness of the reciprocating motion of the cutting unit and the reliability of the structure, while making the overall structure more compact and reasonable.

[0022] like Figure 1 and Figure 3 As shown, in this embodiment, the cutting unit includes: a slider 5, the surface of which is provided with a groove 6, the groove 6 being slidably engaged with a guide rail 4 disposed on the surface of the bracket 2; a first motor 7, which is fixedly connected to the slider 5, the output shaft of the first motor 7 passing through the clearance groove 8 and being splinedly connected to the cutter 9; The above technical solution solves the problem of providing stable support and transmitting power to the rotating cutter 9. Specifically, its working principle and operation steps are as follows: The slider 5, through its surface groove 6, cooperates with the guide rail 4 on the bracket 2, ensuring that the entire cutting unit can only slide smoothly along a predetermined trajectory. The first motor 7 serves as the power source, and its output shaft drives the cutter 9 to rotate at high speed through a spline connection. The spline connection can effectively transmit large torque and adapt to slight axial movement. This enables the cutter 9 to perform precise linear feed motion while rotating at high speed. Combined with the spline connection, this makes power transmission efficient and reliable.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the reciprocating drive mechanism includes: a vertical rod 10, one end of which is fixedly connected to the base plate 1; a second motor 11, which is installed at the other end of the vertical rod 10, the output end of the second motor 11 passing through the vertical rod 10 and connected to a crank 12; a rocker arm 13, one end of which is rotatably connected to the side of the crank 12 away from the output end of the second motor 11, and the other end is rotatably connected to a movable block 14, the movable block 14 being fixedly connected to the slider 5, and a tape channel 3 being formed at the lower end of the bracket 2; The above technical solution solves the problem of reliably converting the rotational motion of the second motor 11 into the linear reciprocating motion required by the cutting unit. Specifically, its working principle and operation steps are as follows: The second motor 11 drives the crank 12 to rotate, and the rocker arm 13 converts the circular motion of the crank into the approximately linear reciprocating motion of the movable block 14, thereby driving the fixed slider 5 and the entire cutting unit to perform forward cutting and backward resetting actions. The tape channel 3 guides and positions the carton and tape. By utilizing the classic crank-rocker mechanism, a stable conversion of motion mode is achieved, which is simple in structure, reliable in operation, and easy to control.

[0024] like Figure 4 and Figure 5 As shown, in this embodiment, the cleaning unit includes: a blade holder 15, which is inserted into a blade holder mounting groove 20 on one side of the slider 5; the blade holder 15 has a slot 16 for inserting a scraper 17; both the scraper 17 and the blade holder 15 have threaded grooves 19; a fastening bolt 18, which passes through the threaded groove 19 between the scraper 17 and the blade holder 15; and a knob 21, which is rotatably located on the side of the slider 5 near the blade holder mounting groove 20, for limiting the movement of the blade holder 15 relative to the slider 5. The above technical solution solves the problem of cumbersome and time-consuming operation when the scraper 17 needs to be replaced due to long-term wear. Specifically, its working principle and operation steps are as follows: The scraper 17 is inserted into the slot 16 of the blade holder 15 and fixed by the fastening bolt 18 passing through the threaded groove 19. The entire blade holder 15 can be inserted or removed from the blade holder mounting slot 20 of the slider 5 and locked or loosened by rotating the knob 21. This achieves quick disassembly and replacement of the scraper 17, greatly simplifies the daily maintenance of the equipment, and reduces downtime.

[0025] like Figure 5 As shown, in this embodiment, the surface of the scraper 17 is provided with a strip groove for the sprayed solvent to slide off; The above technical solution can solve the problem of solvent and adhesive residue mixtures accumulating on the surface of the scraper 17 and affecting the cleaning effect. Specifically, its working principle and operation steps are as follows: During the cleaning process, the sprayed solvent and scraped-off dirt mixture can be smoothly guided and slid down along the strip grooves opened on the surface of the scraper 17. The strip grooves improve the drainage performance of waste liquid, prevent secondary pollution, and thus improve the overall self-cleaning efficiency. If necessary, a container with an open top can also be set below the strip grooves to receive waste liquid.

[0026] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the spray cleaning unit includes: a piston cylinder 25, which is fixedly mounted on the base plate 1. The surface of the piston cylinder 25 is provided with an outlet hole 26 and an inlet hole 27. Both the outlet hole 26 and the inlet hole 27 are provided with one-way valves. The inlet hole 27 is connected to the solvent storage tank through a conduit 28. The outlet hole 26 is connected to the spray head 29 through the conduit 28. A piston 24 is slidably mounted in the piston cylinder 25. A pressure plate 22 is fixedly connected to the slider 5. One end of the pressure plate 22 is connected to a piston rod 23. The other end of the piston rod 23 away from the pressure plate 22 is connected to the piston 24. The reciprocating motion of the slider 5 relative to the bracket 2 drives the piston 24 to move synchronously in the piston cylinder 25, so as to extract the solvent from the solvent storage tank and squeeze it into the spray head 29. The above technical solution solves the problem of needing an additional power source and control circuit to drive the spray system. Specifically, its working principle and operation steps are as follows: The pressure plate 22 reciprocates synchronously with the slider 5, and drives the piston 24 to reciprocate within the piston cylinder 25 via the piston rod 23. When the piston 24 moves in a certain direction, under negative pressure, the solvent is drawn from the solvent storage tank into the piston cylinder 25 through the one-way valve at the inlet port 27; when the piston 24 moves in the opposite direction, it pressurizes the solvent in the cylinder, forcing the solvent to be delivered to the spray head 29 through the one-way valve at the outlet port 26 and the conduit 28. By using the reciprocating motion of the cutting unit itself as a power source, automatic and precise synchronization of spraying and cutting actions is achieved, eliminating the need for electrical control, resulting in a simple structure and energy saving.

[0027] like Figure 1 and Figure 3 As shown, in this embodiment, the surface of the slider 5 is provided with an adjustable support frame, which is connected to the spray head 29 to adjust the spray direction of the adjustable support frame; The above technical solution solves the problem of inaccurate spray positioning and reduced cleaning effectiveness caused by manufacturing tolerances or component wear. Specifically, its working principle and operating steps are as follows: An adjustable support frame mounted on the surface of the slider 5 is used to fix the spray head 29. The angle of the adjustable support frame can be changed through a tension adjustment mechanism, thereby finely adjusting the spray direction of the spray head 29 to ensure it is always accurately aligned upstream of the contact area between the cutter 9 and the scraper 17. This ensures that the solvent is always sprayed to the most effective position, greatly improving the reliability and adaptability of the self-cleaning system.
