Description

Technical Field

[0001] The utility model relates to the technical field of labelling machines, in particular to a knife disc locking structure for labelling machines. Background Art

[0002] A sleeve labeling machine is a packaging equipment used in many industries such as food, beverages, and pharmaceuticals. It is mainly used to apply labels to product packaging to identify product information, production date, expiration date, etc. Its main working principle is to complete the labeling of products through a series of mechanical devices working together, including a series of complex steps such as material transmission, label detection, cutting, and attachment. The cutter disc of a sleeve labeling machine is an important component of the sleeve labeling machine. It is mainly responsible for the precise cutting of label materials. It is usually composed of a series of blades, knife holders, transmission mechanisms, etc., and can maintain cutting accuracy and repeatability during high-speed movement. In order to ensure that mechanical devices such as the cutter disc remain stable in a specific position to prevent accidental movement or damage, and also to reduce downtime caused by accidental movement of the cutter disc, a locking structure for the cutter disc of a sleeve labeling machine is proposed.

[0003] A search revealed a Chinese patent document, publication number CN212606363U, which discloses a blade disc for a labeling machine with stable transmission. This device replaces the traditional metal disc drive with a belt drive between the rotating shafts. The belt's ductility effectively meets the needs of high-speed transmission and increases the blade disc's service life. However, in actual use, this device fails to effectively lock components such as the blade and rotating shaft. Frequent motor starts and stops can cause the blade to continue rotating due to inertia or other forces, potentially leading to miscutting of labels and reducing overall practicality. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the utility model provides a knife disc locking structure for a labeling machine, which has the advantages of stable structure, rapid locking, improved device safety and service life, and solves the above technical problems.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a knife disc locking structure for a labeling machine, comprising a box body, an inner bottom surface of the box body is installed with a rotating shaft and a vertical plate, an outer side surface of the vertical plate is fixedly installed with a first cylinder, an output shaft of the first cylinder is fixedly connected to a first baffle, an inner side surface of the box body is fixedly installed with a partition and a second cylinder, a discharge pipe is fixedly installed inside the partition, the output shaft of the second cylinder is fixedly connected to a second baffle, a first synchronous wheel and a second synchronous wheel are fixedly installed on the outer side surface of the rotating shaft, a base is fixedly installed on the right side surface of the box body, a servo motor is fixedly installed on the top surface of the base, the output shaft of the servo motor is fixedly connected to a third synchronous wheel, and a blade is fixedly installed on the top of the rotating shaft.

[0008] Preferably, the number of the rotating shafts is four, the number of the partitions is two, and the four rotating shafts are all installed inside the two partitions.

[0009] Through the above technical solution, the four rotating shafts can respectively drive the first synchronous wheel, the second synchronous wheel, the blade and other parts to rotate, and the two partitions can not only effectively separate these parts so that they do not interfere with each other, but also the partitions can limit the position of the rotating shaft and make its operation stable, providing a guarantee for the normal operation of the entire device.

[0010] Preferably, the number of the vertical plate, the first baffle and the second baffle is two, and the number of the first cylinder and the second cylinder is four.

[0011] Through the above technical solution, when the servo motor starts and stops frequently, the four first cylinders and the second cylinders are started, and the output shafts of the four first cylinders can respectively drive the two first baffles to move outward, and the output shafts of the four second cylinders can respectively drive the two second baffles to move inward. Through the cooperation between the two first baffles and the two second baffles, the four rotating shafts can be effectively locked to prevent them from continuing to drive the blades to rotate under the action of inertia and other forces, thereby ensuring the overall stability of the device and avoiding unnecessary waste of resources.

[0012] Preferably, grooves are formed on the inner side surfaces of the first baffle and the second baffle, and brake pads are fixedly installed inside the grooves.

[0013] Through the above technical solution, when the first baffle and the second baffle move to the position of the rotating shaft, the groove and the brake pad inside it can effectively clamp and fix it to prevent it from continuing to rotate. The brake pad can increase the friction when it contacts the rotating shaft, thereby providing a good locking effect and improving the overall stability of the device.

[0014] Preferably, there are four first synchronous wheels, the internal transmissions of the four first synchronous wheels are connected with a first belt, and the internal transmissions of the second synchronous wheel and the third synchronous wheel are connected with a second belt.

[0015] Through the above technical solution, when the servo motor is started, the output shaft of the servo motor can drive the third synchronous wheel to rotate. The third synchronous wheel can drive the second synchronous wheel and one of the rotating shafts and the first synchronous wheel to rotate through the second belt. This first synchronous wheel can drive the other first synchronous wheels and the rotating shaft to rotate together through the first belt, thereby effectively driving the blade to rotate and complete the cutting, thereby improving the overall working efficiency of the device.

[0016] Preferably, the number of the blades is four.

[0017] Through the above technical solution, the four rotating shafts can respectively drive the four blades to rotate in the same direction when rotating, thereby effectively cutting the labels. At the same time, the four blades can be effectively rotated intermittently by frequently starting and stopping the servo motor, so that the labels can be continuously cut at equal distances. At the same time, the labels can fall out from the bottom of the device through the discharge pipe, thereby improving the overall working efficiency of the device.

[0018] Compared with the existing technology, the utility model provides a knife disc locking structure for a labeling machine, which has the following beneficial effects:

[0019] 1. The utility model starts the servo motor, and the output shaft of the servo motor can drive the third synchronous wheel to rotate. The third synchronous wheel can drive the second synchronous wheel and one of the rotating shafts and the first synchronous wheel to rotate through the second belt. This first synchronous wheel can drive the other first synchronous wheels and the rotating shaft to rotate together through the first belt, thereby effectively driving the four blades to rotate and complete the cutting of the labels. The four blades can be effectively rotated intermittently by frequently starting and stopping the servo motor, so that the labels can be continuously cut at equal distances. At the same time, the labels can be dropped from the bottom of the device through the discharge pipe, thereby improving the overall working efficiency of the device.

[0020] 2. The utility model starts the four first cylinders and the second cylinder, and the output shafts of the four first cylinders can respectively drive the two first baffles to move outward, and the output shafts of the four second cylinders can respectively drive the two second baffles to move inward. When the first baffle and the second baffle move to the position of the rotating shaft, the groove and the brake pads inside them can effectively clamp and fix them to prevent them from continuing to drive the blade to rotate under the action of inertia and other forces. The brake pads can increase the friction when they contact the rotating shaft, and thus can provide a good locking effect, which not only ensures the overall stability of the device, but also avoids unnecessary waste of resources; the other two partitions can not only effectively separate the first cylinder, the first synchronous wheel, the blade and other parts so that they do not interfere with each other, but also the partitions can limit the position of the rotating shaft and make its operation stable, providing a guarantee for the normal operation of the entire device.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4A knife disc locking structure for a labeling machine includes a box body 1, a rotating shaft 2 and a vertical plate 3 are installed on the inner bottom surface of the box body 1, a first cylinder 4 is fixedly installed on the outer side surface of the vertical plate 3, and the output shaft of the first cylinder 4 is fixedly connected to the first baffle 5, a partition 6 and a second cylinder 7 are fixedly installed on the inner side surface of the box body 1, a discharge pipe 8 is fixedly installed inside the partition 6, and the output shaft of the second cylinder 7 is fixedly connected to the second baffle 9, a first synchronous wheel 10 and a second synchronous wheel 11 are fixedly installed on the outer side surface of the rotating shaft 2, a base 12 is fixedly installed on the right side surface of the box body 1, a servo motor 13 is fixedly installed on the top surface of the base 12, the output shaft of the servo motor 13 is fixedly connected to the third synchronous wheel 14, and a blade 15 is fixedly installed on the top of the rotating shaft 2.

[0028] Specifically, there are four rotating shafts 2 and two partitions 6, and all four rotating shafts 2 are mounted inside the two partitions 6. The advantage is that, through this structure, the four rotating shafts 2 can respectively drive the first synchronous wheel 10, the second synchronous wheel 11, the blade 15 and other components to rotate, and the two partitions 6 can not only effectively separate these components from interfering with each other, but also limit the position of the rotating shafts 2 and ensure stable operation, providing a guarantee for the normal operation of the entire device.

[0029] Specifically, there are two vertical plates 3, two first baffles 5, and two second baffles 9, and four first cylinders 4 and four second cylinders 7. This structure advantageously allows the servo motor 13 to activate the four first cylinders 4 and the second cylinder 7 during frequent starts and stops. The output shafts of the four first cylinders 4 can respectively drive the two first baffles 5 to move outward, while the output shafts of the four second cylinders 7 can respectively drive the two second baffles 9 to move inward. The two first baffles 5 and the two second baffles 9 can cooperate with each other to effectively lock the four rotating shafts 2, preventing them from continuing to rotate the blades 15 due to forces such as inertia. This ensures the overall stability of the device and avoids unnecessary waste of resources.

[0030] Specifically, the inner side surfaces of the first baffle 5 and the second baffle 9 are each formed with a groove 16, and a brake pad 17 is fixedly mounted inside the groove 16. The advantage of this structure is that when the first baffle 5 and the second baffle 9 move to the position of the rotating shaft 2, the groove 16 and the brake pad 17 therein can effectively clamp and fix them to prevent them from continuing to rotate. The brake pad 17 can increase the friction when it contacts the rotating shaft 2, thereby providing a good locking effect and improving the overall stability of the device.

[0031] Specifically, there are four first synchronous wheels 10, each of which is internally connected to a first belt 18 for transmission, and the second and third synchronous wheels 11 and 14 are internally connected to a second belt 19 for transmission. Advantageously, this structure allows the servo motor 13 to be started, with its output shaft driving the third synchronous wheel 14 to rotate.

The first synchronous wheel 10, via the first belt 18, can then drive the other first synchronous wheels 10 and the rotating shaft 2 to rotate together, effectively driving the blade 15 to rotate and complete cutting, thereby improving the overall efficiency of the device.

[0032] Specifically, there are four blades 15. The advantage is that, through this structure, the four rotating shafts 2 can respectively drive the four blades 15 to rotate in the same direction when rotating, thereby effectively cutting the labels. At the same time, the servo motor 13 can be frequently started and stopped to effectively make the four blades 15 rotate intermittently, so that the labels can be continuously cut at equal distances. At the same time, the labels can be dropped from the bottom of the device through the discharge pipe 8, thereby improving the overall working efficiency of the device.

[0033] When in use, the servo motor 13 is started, and the output shaft of the servo motor 13 can drive the third synchronous wheel 14 to rotate. The third synchronous wheel 14 can drive the second synchronous wheel 11 and one of the rotating shafts 2 and the first synchronous wheel 10 to rotate through the second belt 19. This first synchronous wheel 10 can drive the other first synchronous wheels 10 and the rotating shaft 2 to rotate together through the first belt 18, thereby effectively driving the four blades 15 to rotate and complete the cutting of the labels. The four blades 15 can be effectively rotated intermittently by frequently starting and stopping the servo motor 13, so that the labels can be continuously cut at equal distances. At the same time, the labels can be dropped from the bottom of the device through the discharge pipe 8, thereby improving the overall working efficiency of the device; in addition, when the servo motor 13 is frequently started and stopped, the four first cylinders 4 and the second cylinder 7 are started, and the output of the four first cylinders 4 The shaft can drive the two first baffles 5 to move outward respectively, and the output shafts of the four second cylinders 7 can drive the two second baffles 9 to move inward respectively. When the first baffle 5 and the second baffle 9 move to the position of the rotating shaft 2, the groove 16 and the brake pad 17 inside it can effectively clamp it to prevent it from continuing to drive the blade 15 to rotate under the action of inertia and other forces. The brake pad 17 can increase the friction when it contacts the rotating shaft 2, and thus can provide a good locking effect, which not only ensures the overall stability of the device, but also avoids unnecessary waste of resources; the other two partitions 6 can not only effectively separate the first cylinder 4, the first synchronous wheel 10, the blade 15 and other parts so that they do not interfere with each other, but also the partition 6 can limit the position of the rotating shaft 2 and make its operation stable, providing a guarantee for the normal operation of the entire device.
