Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a packaging machine upper and lower belt isolation device. Background Technology

[0002] After being manufactured, cardboard boxes are usually folded. They are then unfolded into a box shape for later use. To facilitate subsequent transfer and transportation, a strapping machine is generally used to pack several folded cardboard boxes together. The entire strapping process of a strapping machine involves several steps: feeding the strap, feeding the strap into position, pressing the strap head, collecting the strap, pressing the strap tail, cutting the strap, the welding mechanism making the buckle, the bottom plate opening and discharging the strap, and the machine head resetting.

[0003] Currently, most automatic strapping machines on the market rely on the following traditional technical solutions to control whether the cable ties are properly delivered: Traditional strapping machines have a fixed feeding time. After the control system starts the feeding motor, it begins timing. When the preset time is reached, it assumes that the cable tie has been delivered to the designated position, stops feeding, and then proceeds to the tensioning and heat sealing process.

[0004] However, this approach has a significant drawback: the termination of the cable tie feeding process is based on an estimate of the feeding motor's running time, rather than on the detection of the actual position of the cable tie. In actual production, the cable tie may fail to reach the correct position within the fixed time due to increased frictional resistance with the guide groove, its own bending deformation, or slippage of the transmission mechanism. This will cause the machine to force subsequent operations before the cable tie has fully formed an effective loop, resulting in empty or loosely secured waste products, severely impacting packaging quality and production efficiency. Furthermore, in the event of a tape jam, the motor will continue to run until the timer ends, easily leading to motor overload, cable tie breakage, or even damage to transmission components.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an upper and lower strap isolation device for a strapping machine, which can directly, accurately, and reliably detect whether the strapping is being delivered in place, thereby further improving the production efficiency and automation level of the strapping machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A packing machine with an upper and lower isolation device includes a feeding seat, a guide slide, a sliding block, a lever, and a belt induction switch. The feeding seat has a first feeding groove, the guide slide is located on the side of the first feeding groove, the guide slide has a groove, the sliding block is slidably connected to the groove, the lever is rotatably connected to the sliding block, a spring is provided in the sliding block, the front end of the lever extends into the first feeding groove, the side of the rear end of the lever abuts against the spring, and the belt induction switch is fixedly connected to the guide slide and is located on the side of the rear end of the lever.

[0009] Furthermore, the sliding block has a receiving groove on its side, a mounting hole that runs vertically through the receiving groove, a rotating shaft in the mounting hole, and a paddle sleeved on the rotating shaft.

[0010] Furthermore, the side wall of the receiving groove is provided with a mounting groove, and the spring is disposed in the mounting groove.

[0011] Furthermore, the sliding block includes a lower slider and an upper slider, which are fastened together by screws.

[0012] Furthermore, the rear end of the lower slider is provided with an adapter groove.

[0013] Furthermore, the lower slider is provided with a second feed groove, and a partition is provided inside the second feed groove.

[0014] Furthermore, the partition and the lower slider are fastened together by screws.

[0015] Furthermore, the feed end of the second feed trough is chamfered.

[0016] Furthermore, the front end of the paddle is provided with a top band, the side wall of the top band is provided with an inclined top surface, and the front end of the inclined top surface is provided with a rounded corner.

[0017] Furthermore, the bottom of the first feed trough is provided with a hot melt trough.

[0018] This utility model provides an upper and lower isolation device for a packing machine. It has the following beneficial effects:

[0019] 1. In this invention, the triggering of the inductive switch is directly determined by the physical position of the cable tie head itself. Only when the cable tie truly abuts against the front end of the lever and pushes the lever to swing will it be recorded as being in position. This is a position triggering mechanism that eliminates interference from indirect factors such as time and current, fundamentally ensuring the accuracy and reliability of the detection.

[0020] 2. This utility model has a simple structure, a stable and reliable detection process, and an extremely low failure rate. The equipment can operate continuously and efficiently, improving overall equipment efficiency. Furthermore, the system only proceeds to the next step after receiving a positioning signal. This avoids forced operation under abnormal conditions, thus protecting the mechanical structure and motor, and preventing the continuous generation of defective products.

[0021] 3. In this invention, the tape arrival sensor switch cannot be turned off when the lever is not reset. Therefore, the tape arrival sensor switch can be used to control and record tape arrival and control the tape feeding function. In addition, the tape arrival sensor switch can also be connected to the monitoring system on the production line to record each successful strapping for production statistics and quality traceability.

Detailed Implementation

[0026] 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. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see the appendix Figure 1 - Appendix Figure 3This utility model embodiment provides a packing machine upper and lower belt isolation device, including a feeding seat 1, a guide slide 2, a sliding block 3, a lever 4, and a belt induction switch 5. The feeding seat 1 is provided with a first feeding groove 11, and the bottom of the first feeding groove 11 is provided with a hot melt groove 12, in which a lower hot melt block is installed. The guide slide 2 is located on the side of the first feeding groove 11, and the guide slide 2 is provided with a sliding groove 21. The extension direction of the sliding groove 21 is perpendicular to the extension direction of the first feeding groove 11. The sliding block 3 is slidably connected to the sliding groove 21, and the lever 4 is rotatably connected to the sliding block 3. A spring 6 is provided in the sliding block 3. The front end of the lever 4 extends into the first feeding groove 11, and the side of the rear end of the lever 4 abuts against the spring 6. The belt induction switch 5 is fixedly connected to the guide slide 2 and is located on the side of the rear end of the lever 4.

[0028] In this embodiment, the sliding block 3 has a receiving groove 31 on its side, and the extending direction of the receiving groove 31 is parallel to the extending direction of the sliding groove 21. The receiving groove 31 has a through mounting hole 32, and a rotating shaft 33 is provided in the mounting hole 32. The lever 4 is sleeved on the rotating shaft 33. When the cable tie abuts against the front end of the lever 4, the lever 4 can rotate around the axis of the rotating shaft 33. The side wall of the receiving groove 31 has a mounting groove 34, and a spring 6 is provided in the mounting groove 34. One end of the spring 6 can be fixedly connected in the mounting groove 34. The elastic force of the spring 6 is less than the abutting force of the cable tie, so that when the cable tie is heat-melted and cut, the spring 6 can abut against the rear end of the lever 4 to reset the lever 4.

[0029] In this embodiment, to facilitate the installation of the sliding block 3, the sliding block 3 includes a lower slider 35 and an upper slider 36, which are fastened together by screws. Furthermore, the rear end of the lower slider 35 is provided with an adapter groove 351. Specifically, the adapter groove 351 can be connected to the piston rod of a cylinder, so that the cylinder pulls the lower slider 35, thereby causing the sliding block 3 to slide within the groove 21.

[0030] In this embodiment, the upper surface of the lower slider 35 is provided with a second feeding groove 352, and a partition 353 is provided inside the second feeding groove 352. The partition 353 separates the first feeding groove 11 from the second feeding groove 352, thereby separating the cable tie into upper and lower sections. Specifically, the partition 353 and the lower slider 35 are fastened together by screws. Furthermore, the feeding end of the second feeding groove 352 is chamfered to facilitate the entry of the front end of the cable tie into the second feeding groove 352 during feeding.

[0031] In this embodiment, the front end of the lever 4 is provided with a top band portion 41, and the side wall of the top band portion 41 is provided with an inclined abutment surface 42. When the cable tie fully abuts the top band portion 41, the inclined abutment surface 42 can remain perpendicular to the cable tie, ensuring the positioning of the cable tie. The front end of the inclined abutment surface 42 is provided with a rounded corner, which facilitates the cable tie abutting and driving the lever 4 to swing.

[0032] The working principle of this utility model:

[0033] During packaging, the cylinder drives the sliding block 3 to move forward to below the first feeding slot 11, which is separated from the second feeding slot 352. The cable tie is fed into the second feeding slot 352 via a conveyor mechanism, then enters the first feeding slot 11 and exits from the feeding seat 1. Afterwards, the front end of the cable tie is manually inserted into the first feeding slot 11 from the rear end of the feeding seat 1. As the cable tie moves forward, it abuts against the top part 41 of the lever 4 until it stops moving. At this time, the top part 41 of the lever 4 rotates and swings around the rotating shaft 33 due to the abutment, causing the rear end of the lever 4 to swing to below the tape sensing switch 5, where it is sensed. Then, the cylinder drives the sliding block 3 to reset, and the lever 4, after separating from the front end of the cable tie, resets under the elastic force of the spring 6, thus completing one tape recording process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
