Description

Technical Field

[0001] This utility model relates to the technical field of gluing machines, specifically an adjustable gluing machine. Background Technology

[0002] Carton gluing machines are automated or semi-automated equipment used in the packaging industry to glue and fix folded cardboard boxes through processes such as gluing and pressing. They are widely used in packaging production in the food, daily chemical, electronics, and gift industries. There are various types of carton gluing machines, among which adjustable carton gluing machines are common and can adapt to more carton sizes. These are widely used in the industry. One type of adjustable carton gluing machine allows for adjustment of all parts to accommodate different carton sizes. The pressing mechanism used to apply the glue to the carton can also be adjusted to ensure pressing quality. However, this common type of adjustable carton gluing machine still has some shortcomings:

[0003] The pressing mechanism consists of multiple rollers that press the glue against the cardboard box. However, with prolonged use, the internal bearings may wear down, causing the rollers to jam or rotate off-axis, resulting in damage to the surface of the cardboard box. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable gluing machine to solve the problem mentioned in the background art, which involves a pressing mechanism with multiple rollers that press the glue against the carton. However, with prolonged use, the internal bearings wear down, causing the rollers to jam or rotate off-axis, resulting in damage to the surface of the carton.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable box gluing machine, comprising a box gluing machine body, with side supports fixedly connected to both sides of one end of the box gluing machine body, and an adjustment support assembly provided on one side of each of the two side supports, wherein multiple central shafts are provided inside the adjustment support assembly, and self-detection roller assemblies are provided on the surface of each of the multiple central shafts, and detection mechanisms are provided on both sides of the surface of each central shaft.

[0006] Preferably, the adjusting support assembly includes a hydraulic cylinder, which is fixedly mounted on the side bracket. The output end of the hydraulic cylinder is fixedly connected to a pressing frame, and multiple central shafts are fixedly connected to the pressing frame, which is beneficial for adjusting the distance between the two pressing mechanisms.

[0007] Preferably, a plurality of receivers are fixedly installed on one side of the inner wall of the pressing frame, and the plurality of receivers correspond to a plurality of central shafts respectively.

[0008] Preferably, the self-detection roller assembly includes a pressing roller, one end of which is fixedly connected to an installation ring, and a transmitter is fixedly installed on the surface of the installation ring, which helps staff to detect roller problems in a timely manner and prevent damage to the surface of the carton.

[0009] Preferably, bearings are fixedly installed at both ends of the inner wall of the pressing roller, and both bearings are sleeved on the central shaft. A rubber layer is provided on the surface of the pressing roller.

[0010] Preferably, the detection mechanism includes a detection bracket, which is fixedly mounted on a central shaft. Multiple detection sleeves are fixedly connected to the outer side of the detection bracket. Pressure sensors are provided at the bottom of the inner walls of the multiple detection sleeves. Limiting grooves are provided on both sides of the inner walls of the detection sleeves, which helps to greatly reduce the damage to the carton.

[0011] Preferably, a detection slide rod is slidably connected inside the detection slide sleeve, and limit sliders are fixedly connected to both sides of the detection slide rod. The surface of the limit slider is slidably connected to the inside of the limit groove. A rolling steel ball is provided at one end of the detection slide rod, and a trigger rod is fixedly connected to the other end of the detection slide rod. A return spring is fixedly connected between the detection slide rod and the detection slide sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the adjustable support component can adjust the distance between the pressing mechanisms, which is conducive to making the pressing mechanisms have an adjustable and appropriate spacing, and ensuring the adhesion effect of the glue on both sides to the carton.

[0013] The system is equipped with a detection mechanism. The rolling steel ball contacts the inner wall of the pressing roller. If the pressing roller rotates off-axis, it will squeeze the rolling steel ball, the detection slide rod and the trigger rod to move towards the pressure sensor and contact the pressure sensor. This will cause the pressure sensor to send a signal to the control module, and the control module will issue a warning signal, which will greatly reduce the damage to the carton.

[0014] Equipped with a through-beam photoelectric sensor, when the pressing roller gets stuck, the receiver cannot receive the light from the transmitter. At this time, the control module issues an alarm signal, which helps staff to detect problems with the pressing roller in a timely manner and prevent damage to the surface of the carton.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides an adjustable box gluing machine, including a box gluing machine body 1. Side brackets 2 are fixedly connected to both sides of one end of the box gluing machine body 1. An adjustment support assembly is provided on one side of each of the two side brackets 2. Multiple central shafts 5 are provided inside the adjustment support assembly. Self-detection roller assemblies are provided on the surface of the multiple central shafts 5. Detection mechanisms are provided on both sides of the surface of the central shafts 5.

[0023] See Figure 2 , Figure 3 , Figure 4 and Figure 5Furthermore, the adjustment support assembly includes a hydraulic cylinder 3, which is fixedly mounted on the side bracket 2. A pressing frame 4 is fixedly connected to the output end of the hydraulic cylinder 3. Multiple central shafts 5 are fixedly connected to the pressing frame 4. Multiple receivers 10 are fixedly mounted on one side of the inner wall of the pressing frame 4, and each receiver 10 corresponds to one of the central shafts 5. The self-detection roller assembly includes a pressing roller 7, with a mounting ring 8 fixedly connected to one end. A transmitter 9 is fixedly mounted on the surface of the mounting ring 8. Bearings 6 are fixedly mounted on both ends of the inner wall of the pressing roller 7, and both bearings 6 are sleeved on the central shafts 5. A rubber layer is provided on the surface of the pressing roller 7. The detection mechanism includes... A detection bracket 11 is fixedly mounted on the central shaft 5. Multiple detection sleeves 12 are fixedly connected to the outer side of the detection bracket 11. Pressure sensors 14 are provided at the bottom of the inner wall of each detection sleeve 12. Limiting grooves 13 are opened on both sides of the inner wall of the detection sleeve 12. A detection slide rod 16 is slidably connected inside the detection sleeve 12. Limiting sliders are fixedly connected to both sides of the detection slide rod 16. The surface of the limiting slider is slidably connected to the inside of the limiting groove 13. A rolling steel ball 17 is provided at one end of the detection slide rod 16. A trigger rod 18 is fixedly connected to the other end of the detection slide rod 16. A return spring 15 is fixedly connected between the detection slide rod 16 and the detection sleeve 12.

[0024] In use, the cardboard box, after being glued together on both sides, enters between two pressing mechanisms. These pressing mechanisms have a certain length. Before gluing the cardboard box, the distance between the two pressing rollers 7 on both sides is adjusted by activating two hydraulic cylinders 3 according to the cardboard box's specifications, ensuring the quality of the pressing effect between the cardboard box and the glue. After the cardboard box passes through the entire pressing mechanism, the pressing roller 7 rotates around the axis of the central shaft 5 due to the action of the bearing 6. The detection bracket 11 is fixedly connected, and the surface of the rolling steel ball 17 contacts the inner wall of the pressing roller 7. At this time, the return spring 15 is in a compressed state, ensuring that the rolling steel ball 17 always contacts the pressing roller 7. As the pressing roller 7 rotates, the rolling steel ball 17 rotates at the end of the detection slide rod 16. If the bearing 6 wears out after prolonged use, the pressing roller 7 will press towards the cardboard box when it rotates. The rotation of roller 7 deviates from the axis of the central shaft 5. Therefore, when bearing 6 wears, the pressing roller 7 rotates. The pressing roller 7 will squeeze the rolling steel ball 17 and the detection slide bar 16. At this time, the trigger rod 18 will contact the pressure sensor 14. The pressure sensor 14 is subjected to force and sends a signal to the control module. At this time, the control module issues a warning signal to alert the staff. The transmitter 9 and receiver 10 are through-beam photoelectric sensors. The transmitter 9 emits a special infrared light path, and the receiver 10 is set to prioritize this special infrared light path. When the pressing roller 7 is rotating normally, the receiver 10 can receive the signal from the transmitter 9 in a certain regular manner. If the pressing roller 7 is stuck and does not rotate, the receiver 10 receives a light path with a low frequency or no light path signal, and sends a signal to the control module. Then the control module issues a warning signal to remind the staff to perform maintenance.

[0025] In this embodiment, when processing cardboard boxes that need to be glued on both sides, the prepared cardboard boxes are placed at one end of the equipment. The boxes are then conveyed through the gluing machine 1 through processes such as gluing and folding. Afterward, they reach the pressing mechanisms on both sides. After subsequent processing, the previous cardboard box is pushed towards the end of the pressing mechanism. The operator removes the cardboard box from between the pressing mechanisms at the end. The preceding cardboard box, under the influence of the following cardboard box, passes through the entire pressing mechanism, ensuring the adhesion between the glue and the cardboard box. The limiting slider on the detection slide rod 16 slides within the limiting groove 13, limiting the movement range of the detection slide rod 16 and ensuring detection accuracy. The end of the trigger rod 18 has a suitable distance from the pressure sensor 14, improving the accuracy of the detection mechanism and significantly reducing damage to the cardboard boxes. If the pressing roller 7 rotates... In case of deviation or jamming during rotation, the system can promptly alert staff to prevent damage to more cardboard boxes. A control module is already installed inside the gluing machine body 1. Warning signals can be clearly seen on the display screen on the gluing machine body 1, and an audible alert will also be emitted. It should be noted that this utility model is an adjustable gluing machine. All components are general standard parts or parts known to those skilled in the art.
