[0003] The purpose of this utility model is to provide an automatic pressing and cutting device that can automatically apply adhesive to packaging boxes and reset the tape after one application to ensure that the next application process proceeds normally.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This utility model discloses an automatic pressing and cutting device, comprising: a frame connected to an external driving device and capable of moving relative to a packaging box under the drive of the external driving device; a tape conveying mechanism mounted on the frame and used for outputting tape; a tape-applying shaft rotatably mounted on the frame and used for receiving the tape and affixing it to the bottom and side walls of the packaging box; a tape-cutting mechanism located downstream of the tape-applying shaft along the output direction of the tape and capable of cutting the tape; and a recycling mechanism located between the tape conveying mechanism and the tape-applying shaft along the output direction of the tape; wherein: after the tape-cutting mechanism cuts the tape, the recycling mechanism can drive the tape to move in the opposite direction to the output direction of the tape.

[0006] In some embodiments, the tape conveying mechanism includes: a tape holder rotatably mounted on the frame and used to mount a tape reel; and a plurality of glue-feeding rollers spaced apart between the tape holder and the adhesive-applying shaft along the output direction of the tape.

[0007] In some specific embodiments, at least one of the glue-feeding rollers is abutted on both opposite surfaces of the tape.

[0008] In some specific embodiments, the recycling mechanism includes: a lifting drive component mounted on the frame; and a lifting roller abutting against the surface of the tape and connected to the lifting drive component, wherein the lifting drive component can drive the lifting roller to move so that the tape moves in a direction opposite to the output direction of the tape.

[0009] In some specific embodiments, the recycling mechanism further includes: a mounting base slidably mounted on the frame and used to support the lifting roller, the lifting roller being rotatably mounted on the mounting base; and a connecting base, one end of which is connected to the mounting base and the other end of which is connected to the lifting drive component.

[0010] In some more specific embodiments, one of the mounting base and the frame is provided with a slide rail, and the other of the mounting base and the frame is provided with a slider, which is slidably mounted on the slide rail.

[0011] In some embodiments, the tape cutting mechanism includes: a tape cutting drive member mounted on the frame; and a tape cutting blade connected to the power output shaft of the tape cutting drive member, the tape cutting blade having a cutting edge, wherein when the tape cutting drive member drives the tape cutting blade to move toward the tape, the cutting edge can cut the tape.

[0012] In some specific embodiments, the frame is provided with a guide groove, and the cutting blade is slidably mounted in the guide groove.

[0013] In some embodiments, the automatic pressing and cutting device further includes a first swing arm, a first tension spring, and a detection device. The first swing arm is rotatably mounted on the frame. One end of the adhesive application shaft and one end of the adhesive conveying roller of the tape conveying mechanism are respectively rotatably mounted on the first swing arm. One end of the first tension spring is connected to the first swing arm, and the other end is connected to the first mounting part of the frame. The detection device is used to detect the position of the end of the first swing arm connected to the first tension spring.

[0014] In some embodiments, the automatic pressing and cutting device further includes a second swing arm, a bottom roller, and a second tension spring. The second swing arm is rotatably mounted on the frame, and one end of the bottom roller is rotatably mounted on the second swing arm. One end of the second tension spring is connected to the second swing arm, and the other end is connected to a second mounting portion of the frame. Along the output direction of the tape, the bottom roller is located downstream of the adhesive application shaft.

[0015] The automatic pressing and cutting device of this invention has the following advantages: In the actual tape application process, the external drive device drives the entire automatic pressing and cutting device to move to the bottom of the packaging box, and then moves upward. The tape application shaft can press the output tape firmly against the bottom wall of the packaging box. Then, the external drive device drives the automatic pressing and cutting device to move, so that the tape application shaft adheres the tape to the bottom and side walls of the packaging box. After the tape is applied, the tape cutting mechanism cuts the tape, and the recovery mechanism drives the tape to move in the opposite direction to the tape output direction, so that the tape remaining between the tape application shaft and the tape cutting mechanism is pulled back, ensuring that the end of the tape abuts against the tape application shaft and does not droop onto the tape cutting mechanism between the next tape application action. Thus, the automatic pressing and cutting device can realize automatic tape application to the packaging box, and can realize tape reset after one tape application, ensuring that the next tape application process can proceed normally.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This utility model discloses an automatic clamping and cutting device, referenced... Figures 1-3As shown, the automatic pressing and cutting device includes a frame 10, a tape conveying mechanism 20, an adhesive application shaft 30, a tape cutting mechanism 40, and a recycling mechanism 50. The frame 10 is connected to an external drive device and can move relative to the packaging box 1 under the drive of the external drive device. The tape conveying mechanism 20 is mounted on the frame 10 and is used to output tape 2. The adhesive application shaft 30 is rotatably mounted on the frame 10 and is used to receive tape 2 and apply it to the bottom and side walls of the packaging box 1. Along the output direction of tape 2, the tape cutting mechanism 40 is located downstream of the adhesive application shaft 30. The tape cutting mechanism 40 can cut tape 2. Along the output direction of tape 2, the tape cutting mechanism 40 is located between the tape conveying mechanism 20 and the adhesive application shaft 30. After the tape cutting mechanism 40 cuts tape 2, the recycling mechanism 50 can drive tape 2 to move in the opposite direction to the output direction of tape 2. Understandably, during the actual tape application process, the external drive device drives the entire automatic pressing and cutting device to move to the lower end of the packaging box 1, and then moves upward. The tape application shaft 30 can press the output tape 2 firmly against the bottom wall of the packaging box 1. Then, the external drive device drives the automatic pressing and cutting device ( Figure 1 The direction of the solid arrow in the middle indicates the movement direction of the automatic pressing and cutting device, so that the adhesive application shaft 30 applies the tape 2 to the bottom and side walls of the packaging box 1. After the tape 2 is applied, the tape cutting mechanism 40 cuts the tape 2, and the recovery mechanism 50 drives the tape 2 to move in the opposite direction to the output direction of the tape 2, so that the tape 2 remaining between the adhesive application shaft 30 and the tape cutting mechanism 40 is pulled back, ensuring that the end of the tape 2 does not droop onto the tape cutting mechanism 40 between the next application action. Thus, the automatic pressing and cutting device of this embodiment can realize automatic tape application to the packaging box 1, and can realize tape 2 reset after one application, ensuring that the next application process can proceed normally.

[0033] Optionally, the friction between the adhesive roller 30 and the tape 2 generates static electricity, which attracts the tape 2 and prevents the end of the tape 2 from drifting irregularly.

[0034] refer to Figures 1-3 As shown, the tape conveying mechanism 20 includes a tape holder 201 and multiple tape feeding rollers 202. The tape holder 201 is rotatably mounted on the frame 10 and is used to mount the tape reel. Along the output direction of the tape 2, the multiple tape feeding rollers 202 are spaced apart between the tape holder 201 and the adhesive application shaft 30. It can be understood that in actual operation, during the actual adhesive application process, the external drive device drives the entire automatic pressing and cutting device to move to the lower end of the packaging box 1. Then, when the external drive device drives the automatic pressing and cutting device to move, the tape reel on the tape holder 201 can continuously output the tape 2, achieving the sealing of the packaging box 1. The multiple tape feeding rollers 202 serve to position and guide the tape 2, ensuring stable output of the tape 2.

[0035] Optionally, at least one feed roller 202 is abutted on both opposite surfaces of the tape 2. It is understood that during actual output, the presence of at least one feed roller 202 on both surfaces of the tape 2 ensures that the tape 2 remains taut during output, guaranteeing stable output.

[0036] Of course, it should be noted that in other embodiments of this utility model, the tape conveying mechanism 20 may also include only one output drive component. The tape reel is mounted on the output shaft of the output drive component. In actual operation, the output drive component works synchronously with the external drive device to realize the output of the tape 2.

[0037] refer to Figures 1-3 As shown, the recycling mechanism 50 includes a lifting drive 501 and a lifting roller 502. The lifting drive 501 is mounted on the frame 10, and the lifting roller 502 abuts against the surface of the tape 2 and is connected to the lifting drive 501. The lifting drive 501 can drive the lifting roller 502 to move, so that the tape 2 moves in the opposite direction to the output direction of the tape 2. It can be understood that after the tape cutting mechanism 40 cuts the tape 2, the lifting drive 501 drives the lifting roller 502 to rise. During the rising process, the lifting roller 502 can drive the tape 2 to move, thereby recycling the remaining tape 2 at the lower end of the lifting roller 502, preventing the head of the tape 2 from sticking during the next cycle. This structure, which achieves tape 2 recycling by driving the lifting roller 502, is simple in structure, easy to control, and helps to reduce the manufacturing cost of the entire recycling mechanism 50.

[0038] In this embodiment, the adhesive lifting drive 501 is a cylinder. In other embodiments of this utility model, the adhesive lifting drive 501 can also be selected as other linear drive mechanisms such as an electric push rod, and is not limited to a cylinder, depending on actual needs.

[0039] It should be noted that in other embodiments of this utility model, the recycling mechanism 50 may include a rotary drive mounted on the tape conveying mechanism 20. After the tape cutting mechanism 40 cuts the tape 2, the rotary drive drives the tape reel to reverse, which can also play the role of recycling the tape 2.

[0040] Optional, see reference Figure 1As shown, the recycling mechanism 50 also includes a mounting base 503 and a connecting base 504. The mounting base 503 is slidably mounted on the frame 10 and is used to support the lifting roller 502. The lifting roller 502 is rotatably mounted on the mounting base 503. One end of the connecting base 504 is connected to the mounting base 503, and the other end is connected to the lifting drive component 501. It can be understood that fixing the lifting roller 502 with the mounting base 503 facilitates its installation, and connecting the lifting roller 502 to the lifting drive component 501 via the connecting base 504 provides a more stable lifting and lowering drive compared to a direct connection.

[0041] Optionally, the frame 10 is provided with a slide rail 101, and the mounting base 503 is provided with a slider 5031, which is slidably mounted on the slide rail 101. It is understood that during actual operation, as the lifting drive 501 drives the mounting base 503 to rise and fall, the sliding of the slider 5031 relative to the slide rail 101 guides and limits the movement of the mounting base 503, preventing it from tilting. This ensures that the lifting roller 502 can rise and fall stably to achieve the recycling of the tape 2.

[0042] refer to Figures 1-3 As shown, the adhesive cutting mechanism 40 includes an adhesive cutting drive 401 and an adhesive cutting blade 402. The adhesive cutting drive 401 is mounted on the frame 10, and the adhesive cutting blade 402 is connected to the power output shaft of the adhesive cutting drive 401. The adhesive cutting blade 402 has a cutting edge. When the adhesive cutting drive 401 drives the adhesive cutting blade 402 to move towards the tape 2, the cutting edge can cut the tape 2. It can be understood that by driving the movement of the adhesive cutting blade 402 through the adhesive cutting drive 401 to cut the tape 2, the tape 2 can be cut conveniently and quickly, thereby improving the adhesive application efficiency.

[0043] Optionally, the cutting blade is a serrated blade, which allows for easy cutting of the tape 2.

[0044] In this embodiment, the rubber cutting drive 401 is a cylinder. In other embodiments of this utility model, the rubber cutting drive 401 may also be selected as other linear drive mechanisms such as an electric push rod, and is not limited to a cylinder, depending on actual needs.

[0045] Optionally, the frame 10 is provided with a guide groove 102, and the cutting blade 402 is slidably mounted in the guide groove 102. It is understood that during actual operation, when the cutting drive 401 drives the cutting blade 402, the cutting blade 402 can only move within the guide groove 102. The guide groove 102 guides and restricts the cutting blade 402, preventing uneven cuts caused by the cutting blade 402 being skewed.

[0046] refer to Figures 1-3As shown, the automatic pressing and cutting device also includes a first swing arm 60, a first tension spring 70, and a detection device 80. The first swing arm 60 is rotatably mounted on the frame 10. One end of the adhesive application shaft 30 and part of the adhesive conveying roller 202 of the tape conveying mechanism 20 are rotatably mounted on the first swing arm 60. One end of the first tension spring 70 is connected to the first swing arm 60, and the other end is connected to the first mounting part 103 of the frame 10. The detection device 80 is used to detect the position of the end of the first swing arm 60 connected to the first tension spring 70. It can be understood that in the actual working process, the adhesive application shaft 30 contacts the bottom surface of the workpiece according to the preset trajectory to complete the initial bonding. During the initial bonding process, the left side of the first tension spring 70 is fixed to the first mounting plate, and the right side is connected to the top of the first swing arm 60. When the upper part of the first swing arm 60 is approached by the detection device 80 during the contact process, it indicates that the initial bonding is completed. The external drive device can then drive the entire automatic pressing and cutting device to move along the bottom wall of the packaging box 1 to adhere the tape 2 to the bottom of the packaging box 1.

[0047] Optionally, the detection device 80 is adjustablely mounted on the frame 10 using screws. During actual operation, the pressure between the adhesive roller 30 and the packaging box 1 can be controlled by adjusting the position of the detection device 80. In this embodiment, the detection device 80 is a proximity switch. Of course, in other embodiments of this invention, the detection device 80 can be selected according to actual needs.

[0048] refer to Figures 1-3 As shown, the automatic pressing and cutting device also includes a second swing arm 90, a bottom roller 100, and a second tension spring 200. The second swing arm 90 is rotatably mounted on the frame 10, and one end of the bottom roller 100 is rotatably mounted on the second swing arm 90. One end of the second tension spring 200 is connected to the second swing arm 90, and the other end is connected to the second mounting part 104 of the frame 10. Along the output direction of the tape 2, the bottom roller 100 is located downstream of the adhesive application shaft 30. It can be understood that in the actual working process, after the tape 2 is applied to the bottom wall of the packaging box 1, it is also necessary to apply the tape 2 to the side wall of the packaging box 1. During the upward movement of the automatic pressing and cutting device driven by the external drive device, the tape 2 pressed against the side wall of the packaging box 1 by the adhesive application shaft 30 can be pressed again by the bottom roller 100, which helps to improve the tightness of the tape 2 and improve the application quality. When the bottom roller 100 is attached to the side wall of the packaging box 1, the second swing arm 90 will rotate to compress the second tension spring 200. The reaction force of the second tension spring 200 on the second swing arm 90 can ensure that the second swing arm 90 drives the bottom roller 100 to press firmly on the side wall of the packaging box 1, further improving the tightness of the tape 2, thereby further improving the adhesive application quality.

[0049] refer to Figures 1-3As shown, the frame 10 includes two spaced-apart wall panels, with the first swing arm 60 and the second swing arm 90 respectively mounted on one wall panel. This ensures that the first swing arm 60 and the second swing arm 90 do not interfere with each other, and simplifies the structure of the frame 10.

[0050] The working process of the automatic clamping and cutting device in this embodiment is described in detail below:

[0051] Initial stage: Tape 2 is precisely guided to the adhesive application station by tape conveyor mechanism 20;

[0052] Adhesive application stage:

[0053] An external drive unit drives the frame 10 to move, causing the adhesive roller 30 to contact the packaging box 1 along a preset trajectory to complete the initial bonding. During the initial bonding process, the left side of the first tension spring 70 is fixed to the first mounting plate, and the right side is connected to the top of the first swing arm 60. When the upper part of the first swing arm 60 is approached by the proximity detection device 80 during the contact process, it indicates that the initial bonding is complete.

[0054] An external drive unit completes continuous adhesive application along a set path.

[0055] Finishing steps:

[0056] The cutting drive 401 drives the cutting blade 402 to perform the cutting action, ensuring a clean cut.

[0057] The adhesive lifting drive 501 drives the adhesive lifting roller 502 to rise, causing the excessively long adhesive tape 2 at the lower end of the adhesive application shaft 30 to be retracted, preventing the head of the adhesive tape 2 from sticking during the next cycle of work, and preparing for the next work cycle.
