Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, specifically to a conveying mechanism and a carton sealing machine for tape sealing. Background Technology

[0002] After storing items in a cardboard box, the box opening needs to be sealed with tape to prevent the contents from falling out during handling. This is where a carton sealing machine comes in handy, using self-adhesive tape to seal the top of the carton, making the product easier to store and transport.

[0003] Existing tape sealing methods involve conveying boxes containing items to a sealing device via a transport mechanism, where the tape is directly applied. However, the lack of effective restraint devices on the sides of the box during this process means the box may be tilted or unstable during tape application. This tilted position can result in uneven tape application, or even poor adhesion between the tape and the box surface, affecting both the seal's strength and aesthetics. Utility Model Content

[0004] The purpose of this utility model is to provide a conveying mechanism and a sealing machine for a tape sealing machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying mechanism for a tape sealing machine, comprising a base and a clamping part:

[0006] A roller is rotatably mounted on the top of the base, and a conveyor belt is horizontally mounted on the top of the base. A clamping part is located at the bottom of the base and has a connecting frame mounted on the base. A bidirectional lead screw is rotatably mounted inside the connecting frame, and a motor is mounted at one end of the connecting frame. The output end of the motor is connected to the bidirectional lead screw. A slider is slidably mounted inside the connecting frame, and the bidirectional lead screw passes through the slider and is threadedly connected to the slider. A connecting rod is mounted on the top of the slider, and a clamping plate is mounted on the side of the connecting rod. A sensor is mounted at one end of the clamping plate, and the sensor is used to control the operation of the motor.

[0007] By adopting the above technical solution, automatic clamping and positioning of cartons can be achieved, ensuring the stability of the cartons during transportation and avoiding problems such as uneven sealing or weak tape adhesion caused by cartons tilting or shifting. Sensors can monitor the contact status between the clamping plates and the cartons in real time and adjust the position of the clamping plates by controlling the motor, thereby adapting to cartons of different sizes and improving the versatility and automation of the equipment.

[0008] Preferably, the base also has a limiting frame disposed on the top of the base, and the connecting rod passes through the limiting frame and is longitudinally slidably connected to the limiting frame.

[0009] By adopting the above technical solution, the range of motion of the connecting rod can be further limited, ensuring that the clamping plate does not move excessively or deviate from the predetermined position when clamping the carton, thereby improving the clamping accuracy and stability. The design of the limit frame can also prevent the clamping plate from shaking during high-speed operation, ensuring the smooth operation of the equipment.

[0010] Preferably, there are two sliders, and the two sliders are respectively nested and threaded to both ends of the bidirectional lead screw.

[0011] By adopting the above technical solution, the synchronous and symmetrical movement of the two clamping plates can be achieved, ensuring that the carton is subjected to uniform force during the clamping process.

[0012] Preferably, there are two clamps, and the two clamps are designed to be mirror-symmetrical along the center line of the base.

[0013] By adopting the above technical solution, the mirror-symmetrical design of the clamping plate can apply clamping force evenly, ensuring that the carton remains centered during transportation and avoiding the carton shifting or tilting due to asymmetrical clamping.

[0014] Preferably, the clamping part also has a curved surface disposed at one end of the clamping plate, which is disposed next to the sensor.

[0015] By adopting the above technical solution, the friction between the clamping plate and the carton can be reduced through the curved surface design, preventing damage to the carton surface due to excessive clamping force. At the same time, the curved surface can also guide the carton smoothly into the clamping area, ensuring the smoothness and accuracy of the clamping process.

[0016] Preferably, the clamping part also has a rotating frame rotatably disposed inside the clamping plate, and a roller is rotatably disposed at one end of the rotating frame.

[0017] By adopting the above technical solution, the sliding friction between the clamp and the carton can be reduced through the rotational movement of the rollers.

[0018] Preferably, a spring is provided at one end of the rotating frame near the clamping plate, and the spring is located between the clamping plate and the rotating frame.

[0019] By adopting the above technical solution, the distance between the roller and the carton can be adjusted by the elastic force of the spring, ensuring that the clamping force is moderate and avoiding deformation of the carton due to excessive clamping force or failure to effectively fix the carton due to insufficient clamping force.

[0020] A carton sealing machine includes the tape sealing machine conveying mechanism described in any one of the above claims, and the carton sealing machine further includes a sealing unit:

[0021] The sealing section is located on the top of the base. The sealing section has a support frame located on the top of the base. A one-way screw is vertically rotatably installed inside the support frame. A lifting frame is vertically slidably installed on the side of the support frame. The one-way screw passes vertically through the lifting frame and is threadedly connected to the lifting frame. The sealing mechanism is installed inside the lifting frame.

[0022] By adopting the above technical solution, the sealing mechanism can be automatically raised and lowered to adapt to cartons of different heights, ensuring that the tape can be accurately applied to the top cover of the carton.

[0023] Compared with existing technologies, the advantages of this invention are that by incorporating a clamping part, it can automatically clamp and position the carton, ensuring the carton remains stable during transport and avoiding problems such as uneven sealing or weak tape adhesion caused by carton tilting or shifting. Sensors can monitor the contact state between the clamping plate and the carton in real time and adjust the position of the clamping plate by controlling the motor, thereby adapting to cartons of different sizes and improving the versatility and automation of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a conveying mechanism for a tape sealing machine, comprising a base 1 and a clamping part 2.

[0033] A roller 101 is rotatably mounted on the top of the base 1, and a conveyor belt 102 is horizontally mounted on the top of the base 1. There are two conveyor belts 102, which are horizontally arranged relative to each other. The working principle of the conveyor belt 102 is mainly based on the coordinated work of the electric motor drive and the mechanical transmission system. The above is the existing technology and will not be described in detail below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven.

[0034] The clamping part 2 is located at the bottom of the base 1. The clamping part 2 has a connecting frame 201 mounted on the base 1. A bidirectional lead screw 202 is rotatably mounted inside the connecting frame 201. A motor 203 is mounted at one end of the connecting frame 201, and the output end of the motor 203 is connected to the bidirectional lead screw 202. This motor 203 is a servo motor, a high-precision, high-performance motor capable of precisely controlling position, speed, and acceleration. Its working principle is based on a closed-loop control system, mainly composed of a motor, encoder (or sensor), and controller. This is existing technology and will not be elaborated further below. When selecting a model, its power should be matched to the requirements of the device to ensure that the object to be driven is driven.

[0035] A slider 204 is slidably mounted inside the connecting frame 201. A bidirectional lead screw 202 passes through the slider 204 and is threadedly connected to it. A connecting rod 205 is mounted on the top of the slider 204, and a clamping plate 206 is mounted on the side of the connecting rod 205. A sensor 207 is mounted on one end of the clamping plate 206. The sensor 207 controls the operation of the motor 203, enabling automatic clamping and positioning of the carton. This ensures the carton remains stable during transport and prevents problems such as uneven sealing or loose tape adhesion caused by tilting or shifting of the carton. The sensor 207 can monitor the contact status between the clamping plate 206 and the carton in real time and adjust the position of the clamping plate 206 by controlling the operation of the motor 203, thereby adapting to cartons of different sizes and improving the versatility and automation of the equipment.

[0036] Example 2

[0037] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a conveying mechanism for a tape sealing machine, comprising a base 1 and a clamping part 2.

[0038] A limiting frame 103 is fixedly installed on the top of the base 1. This fixing method is an existing detachable fixing method, such as bolt connection or snap-fit ​​connection. The connecting rod 205 passes through the limiting frame 103 and is longitudinally slidably connected to the limiting frame 103, which can further limit the range of motion of the connecting rod 205, ensuring that the clamping plate 206 will not move excessively or deviate from the predetermined position when clamping the carton, thereby improving the clamping accuracy and stability. The design of the limiting frame 103 can also prevent the clamping plate 206 from shaking during high-speed operation, ensuring the smooth operation of the equipment.

[0039] There are two sliders 204, and the two sliders 204 are respectively nested and threaded to both ends of the bidirectional lead screw 202, which can realize the synchronous and symmetrical movement of the two clamping plates 206, ensuring that the carton is subjected to uniform force during clamping. The bidirectional lead screw 202 is a special lead screw structure, the core feature of which is that it can realize two opposite movements on the same lead screw. The above is the prior art, and will not be described in detail below.

[0040] There are two clamping plates 206, which are designed to be mirror-symmetrical along the center line of the base 1. This allows the mirror-symmetrical clamping plates 206 to apply clamping force evenly, ensuring that the carton remains centered during transport and preventing the carton from shifting or tilting due to asymmetrical clamping.

[0041] The clamping part 2 also has a curved surface 208 disposed at one end of the clamping plate 206. The curved surface 208 is located next to the sensor 207. The design of the curved surface 208 reduces the friction between the clamping plate 206 and the carton, preventing damage to the surface of the carton due to excessive clamping force. At the same time, the curved surface 208 can also guide the carton smoothly into the clamping area, ensuring the smoothness and accuracy of the clamping process. The sensor 207 is a laser sensor, which is a device that uses laser technology to detect the presence of objects. The sensor 207 emits a laser beam, which is reflected after encountering an object and received by the sensor 207, thereby determining whether an object exists in front of the sensor 207.

[0042] A rotating frame 209 is rotatably arranged inside the clamping plate 206. A roller 210 is rotatably arranged at one end of the rotating frame 209. The sliding friction between the clamping plate 206 and the carton can be reduced by the rotational movement of the roller 210.

[0043] A spring 211 is provided at one end of the rotating frame 209 near the clamping plate 206. The spring 211 is located between the clamping plate 206 and the rotating frame 209. The spring 211 is in the open state when there is no external force. The elastic force of the spring 211 can be used to adjust the distance between the roller 210 and the carton, ensuring that the clamping force is moderate and avoiding deformation of the carton due to excessive clamping force or failure to effectively fix the carton due to insufficient clamping force.

[0044] Example 3

[0045] Please see Figure 1 , Figure 4 and Figure 5 This embodiment provides another technical solution: a carton sealing machine, including an upper carton sealing machine and a carton sealing section 3.

[0046] The sealing section 3 is located on the top of the base 1. The sealing section 3 has a support frame 301 located on the top of the base 1. A one-way screw 302 is vertically rotatably arranged inside the support frame 301. A lifting frame 303 is vertically slidably arranged on the side of the support frame 301. The one-way screw 302 passes vertically through the lifting frame 303 and is threadedly connected to the lifting frame 303. The one-way screw 302 is equipped with a servo motor as a power source. The servo motor is a high-precision, high-performance motor that can accurately control position, speed and acceleration. Its working principle is based on a closed-loop control system, mainly composed of a motor, encoder (or sensor) and controller. The above is existing technology and will not be elaborated further below. When selecting a model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The lifting frame 303 is equipped with a sealing mechanism 304 inside. The sealing mechanism 304 is equipped with a tape guide device and tape roll. The above is existing technology and will not be elaborated further below. It can realize the automatic lifting of the sealing mechanism 304 to adapt to cartons of different heights and ensure that the tape can be accurately attached to the top cover of the carton.

[0047] Working principle: First, the device is powered on. The boxes to be sealed are placed on the conveyor belt 102 for conveying. During conveying, sensor 207 emits a laser beam. The laser beam is reflected from the box and received by sensor 207, indicating whether sensor 207 is directly in front of the box. Sensor 207 drives the bidirectional lead screw 202 to drive the two sliders 204 to move synchronously until sensor 207 can no longer detect the position of the box. At this point, clamping plates 206 will move to both sides of the box to clamp it. Sensors 207 on clamping plates 206 monitor the clamping status in real time and adjust the position of clamping plates 206 through motor 203 to ensure that the carton remains stable and aligned during conveying. The curved surface 208 at one end of the clamping plate 206 and the roller 210 design reduce friction and prevent damage to the carton, while the spring 211 adjusts the clamping force to prevent the carton from deforming or being loosely clamped. After the carton is stably clamped, the conveyor belt 102 sends it to the bottom of the sealing section 3. The sealing section 3 drives the lifting frame 303 to move up and down via the one-way screw 302, which in turn drives the sealing mechanism 304 to automatically adjust its height to accommodate cartons of different sizes. The sealing mechanism 304 precisely applies tape to the top cover of the carton to complete the sealing operation.
