Description

Technical Field

[0001] This utility model relates to the technical field of filling industry equipment, specifically a material clamping and conveying acceleration device. Background Technology

[0002] In modern packaging production lines in industries such as pharmaceuticals, food, and cosmetics, after products complete preliminary processes such as filling and sealing, they typically need to be transferred via conveyor belt to a fully automatic cartoning machine for final packaging. During this process, the discharge speed of the filling line and the feeding speed of the cartoning machine are often difficult to keep in constant agreement. Cartoning machines operate intermittently, and their inlet pushing or gripping mechanisms require materials to arrive at specific rhythms and intervals for reliable gripping.

[0003] Currently, materials are fed directly into the cartoning machine via a free conveyor belt. This method has the following problems: First, when the filling line speed is higher than the cartoning machine's cycle time, material is prone to accumulation, compression, or even collapse at the cartoning machine's inlet. Operators need to intervene frequently to manage this, which not only affects production efficiency but may also damage the product. Second, materials entering the cartoning machine in a disordered and uneven manner can lead to malfunctions such as gripping failures, empty packages, or material jams, seriously affecting the stability of the cartoning machine's operation and packaging efficiency. In addition, some existing auxiliary conveying devices have fixed structures and lack effective adjustment mechanisms, making it difficult to flexibly adapt to the conveying requirements of bottles or cans of different sizes and shapes, resulting in poor versatility. Utility Model Content

[0004] The purpose of this invention is to provide a material clamping and conveying acceleration device, which has the effect of improving production efficiency and strong versatility.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a material clamping and conveying acceleration device, comprising a fixed plate, a front-to-back adjustable support plate and a movable pad block installed at the top of the fixed plate, a height-adjustable connecting plate installed at the top of the support plate, two front-to-back adjustable support legs installed at the top of the movable pad block, a motor mounting plate fixedly installed at the top of the support legs, a speed-regulating motor fixedly installed at the top of the motor mounting plate, a first synchronous pulley fixedly installed on the drive shaft of the speed-regulating motor, a tension pulley and two second synchronous pulleys rotatably installed below the motor mounting plate, and a synchronous belt drivingly connecting the first synchronous pulley, the second synchronous pulleys and the tension pulley.

[0006] The present invention is further configured such that: the upper surface of the fixing plate is provided with a horizontal fixing groove 1 and a fixing groove 2; the upper and lower surfaces of the movable pad are provided with vertical through grooves, and the lower through groove is connected to the fixing groove 1 by a mounting bolt; the bottom of the support plate is provided with a vertical mounting groove 1, and the fixing groove 1 is connected to the mounting groove 1 by a mounting bolt.

[0007] A further feature of this invention is that the bottom of the support leg is provided with a mounting groove four, and the mounting groove four is connected to the through groove above the movable pad by mounting bolts.

[0008] A further feature of this invention is that the top of the support plate is provided with a second mounting groove, the end of the connecting plate is provided with a mounting hole, the second mounting groove is connected to the mounting hole by mounting bolts, and the middle part of the connecting plate is provided with a notch near the bottom.

[0009] A further feature of this invention is that the surface of the connecting plate is provided with two longitudinal mounting grooves, and the surface of the motor mounting plate is provided with a plurality of evenly spaced fixing holes, and the mounting grooves are connected to the corresponding fixing holes by mounting bolts.

[0010] A further feature of this invention is that a photoelectric sensor is installed at the end of the motor mounting plate near the material outlet, and the photoelectric sensor is electrically connected to the PLC controller inside the cartoning machine.

[0011] In summary, this utility model has the following beneficial effects: This utility model accelerates materials by driving a synchronous belt with a speed-regulating motor, enabling materials to enter the cartoning machine at a stable and orderly rhythm. This completely solves the problems of material accumulation, compression, and jamming caused by speed mismatch at the cartoning machine inlet, ensuring the continuous, efficient, and stable operation of the packaging production line.

The cooperation between the fixed plate and the movable pad enables overall adjustment of the device's front and rear; the cooperation between the support plate and the connecting plate enables flexible adjustment of the equipment height; the cooperation between the mounting groove and the support leg enables adjustment of the front and rear positions of the transmission components; and the cooperation between the connecting plate and the motor mounting plate enables adjustment of the width between the two synchronous belts. This multi-level adjustment mechanism allows the device to quickly and easily adapt to the conveying requirements of bottles, cans, boxes, and other materials of different specifications and sizes, exhibiting strong versatility. The transmission system uses a combination of synchronous pulleys and synchronous belts, with a tensioning pulley ensuring that the transmission is always in the optimal tension state. The transmission is smooth, with low noise and high reliability. The entire device has a compact and reasonable structural design, allowing for easy installation on both sides of existing conveyor belts with minimal modification to the production line, convenient installation, and minimal space occupation.

[0017] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a material clamping and conveying acceleration device is installed on both sides of the feeding conveyor belt of a cartoning machine. It includes a fixed plate 1, a support plate 2, a connecting plate 3, a movable pad 4, a support leg 5, a motor mounting plate 6, a speed regulating motor 601, a first synchronous pulley 602, a second synchronous pulley 603, a tensioning pulley 604, a synchronous belt 605, and a photoelectric sensor 7.

[0019] The fixed plate 1 is the basic installation component of the entire device. It has a horizontally arranged fixed groove 101 and a fixed groove 102 on its upper part. The movable pad 4 cooperates with the fixed groove 101 through the longitudinal through groove on its lower surface, and the front and rear positions are adjusted and fixed by the mounting bolts. The support plate 2 cooperates with the fixed groove 102 through the mounting groove 201 at its bottom, and the front and rear positions are also adjusted by the mounting bolts.

[0020] The top of the support plate 2 is provided with a second mounting groove 202, and one end of the connecting plate 3 is provided with a mounting hole 301. The connecting plate 3 is connected to the second mounting groove 202 by mounting bolts to realize the height adjustment of the connecting plate 3. There is a notch in the middle of the connecting plate 3 near the bottom to avoid the conveying material.

[0021] Two support legs 5 are provided above the movable pad 4. The bottom of the support leg 5 is provided with a mounting groove 4 501, which is connected to the longitudinal through groove on the upper surface of the movable pad 4 by mounting bolts to realize the adjustment of the front and rear position of the support leg 5; a motor mounting plate 6 is fixedly installed on the top of the support leg 5.

[0022] A speed-regulating motor 601 is fixedly mounted on the motor mounting plate 6. A synchronous pulley 602 is mounted on its drive shaft. Two synchronous pulleys 603 and a tension pulley 604 are rotatably mounted below the motor mounting plate 6. A synchronous belt 605 is wrapped around the synchronous pulleys 602, 603, and 604 to form a transmission belt assembly. The tension pulley 604 is used to adjust the tension of the synchronous belt 605 to ensure smooth transmission.

[0023] The surface of the connecting plate 3 is provided with two longitudinal mounting grooves 302, and the surface of the motor mounting plate 6 is provided with multiple sets of evenly spaced fixing holes. By cooperating with the mounting bolts and mounting grooves 302, the longitudinal position of the motor mounting plate 6 and the entire transmission assembly on it can be finely adjusted to adapt to materials of different widths.

[0024] In this embodiment, preferably, a photoelectric sensor 7 is installed at the end of the motor mounting plate 6, near the material outlet. The function of the photoelectric sensor 7 is to detect whether material has arrived at the outlet of the acceleration device. When the material is accelerated and conveyed through the outlet, the photoelectric sensor 7 will detect the signal and transmit the signal to the PLC controller inside the fully automatic cartoning machine. After receiving the signal, the PLC controller of the cartoning machine can accurately trigger subsequent cartoning actions such as gripping, boxing, and box closing, thereby achieving precise coordination and seamless connection between the acceleration conveying device and the working rhythm of the cartoning machine.

[0025] In use, the device is installed in pairs on both sides of the feeding conveyor belt of the cartoning machine. During operation, the filled material is fed into the section where this device is located by the upstream conveyor belt. First, the operator needs to adjust the device according to the size of the material and the cycle time requirements of the cartoning machine. By loosening the corresponding mounting bolts, the front and rear positions of the support plate 2 and the movable pad 4 on the fixed plate 1 can be adjusted independently, thereby initially setting the overall spacing between the two sets of acceleration units. By cooperating the mounting hole 301 on the connecting plate 3 with the mounting groove 202 on the top of the support plate 2, the overall height of the device can be adjusted to ensure that the synchronous belt 605 has a good contact height with the material. By cooperating the mounting groove 501 at the bottom of the support leg 5 with the movable pad 4, the front and rear positions of the motor mounting plate 6 can be finely adjusted. By cooperating the longitudinal mounting groove 302 on the connecting plate 3 with the fixing hole on the motor mounting plate 6, the width between the two synchronous belts 605 can be precisely adjusted to adapt to materials of different diameters or widths. This achieves stable clamping and conveying. After adjusting and tightening all bolts, the equipment can be started. The speed-regulating motor 601 starts working, driving the synchronous belt 605 through the synchronous pulley 602 on its drive shaft. The synchronous belt 605 forms a stable closed-loop transmission under the action of the synchronous pulley 603 and the tension pulley 604. The two synchronous belts 605 move towards each other, generating a forward clamping force and acceleration power on the material passing between them, accelerating the material to a speed that matches the gripping rhythm of the cartoning machine. When the accelerated material reaches the outlet of the device, the photoelectric sensor 7 installed at the end of the motor mounting plate 6 will detect the passage of the material and immediately send a trigger signal to the PLC controller inside the cartoning machine. After receiving the signal, the PLC controller will precisely control the actuator of the cartoning machine (such as the pusher or the robot arm) to perform the gripping or pushing action into the carton, thereby achieving precise synchronization and seamless connection between accelerated conveying and cartoning operation.

[0026] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
