Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a labeling machine with a compacting structure for drinking water production. Background Art

[0002] In some office places, water dispensers are usually used to meet people's drinking water needs. When the bottled water used in the water dispenser is produced, the barrel mouth needs to be sealed and a label is affixed to the outside. On the one hand, it has an advertising effect, and on the other hand, it can remind consumers that the barrel of water is in an unopened state, making it easier for consumers to identify.

[0003] When the existing labeling machine is in operation, the bottled water that has been filled and sealed is transported to the bottom of the labeling machine through an external conveying structure. The labeling machine is started under the guidance of the calibration equipment or other auxiliary equipment of the labeling machine to press and attach the pre-arranged label to the mouth of the bottled water to complete the labeling operation.

[0004] However, when the existing equipment is in operation, the mouth of the bottled water is not completely flat, and there is a small notch on the inside for water outlet. This makes it impossible for the labeling machine to be in a complete contact state when posting. When the labeling mechanism presses the label downward, the notch can easily cause the label to wrinkle or even fail to be stably posted, resulting in defective products and affecting the production efficiency of drinking water. In view of this, we propose a labeling machine with a clamping structure for drinking water production. Utility Model Content

[0009] The top inner wall of the shrinkage groove is fixedly connected with the top of the column, and a return spring is fixedly connected between the bottom end of the column and the inner wall of the movable plate.

[0010] Preferably, a circular cavity having a size matching that of the contact block is formed on the inner wall of the bottom of the labeling seat, and the contact block is arranged inside the circular cavity.

[0011] Preferably, the side plate and the movable plate are respectively arranged at both ends of the contraction groove, and the side plate is arranged on the side of the contraction groove away from the center of the contact block, so that the contact roller is arranged in an inclined shape at the bottom position of the contact block.

[0012] Preferably, the movable cavity is adapted to the movable connecting member, and the length of the movable cavity is greater than the length of the movable connecting member, so that when the left end of the contact roller moves upward, the movable connecting member will not interfere with the deflection of the contact roller.

[0024] In one embodiment of the utility model, a contact block 9 is movably installed on the inner wall of the labeling seat 5, and the top inner wall of the contact block 9 is rotatably connected to the bottom end of the elastic telescopic rod 22, and the top of the elastic telescopic rod 22 is fixedly connected to the top inner wall of the labeling seat 5. A convex ball 10 is fixedly installed on the arc-shaped outer wall of the contact block 9, and a spiral groove 11 is opened on the inner wall of the labeling seat 5. The convex ball 10 is arranged inside the spiral groove 11, and a contraction groove 12 is opened on the lower surface of the contact block 9. The inner wall of the contraction groove 12 is fixedly installed A side plate 13 is provided, and one end of a hinge 14 is hinged on the inner wall of the side plate 13, and a contact roller 15 is rotatably connected to the other end of the hinge 14, and a movable cavity 16 is provided on the inner wall of the end of the contact roller 15 away from the hinge 14, and a movable connecting member 17 is movably installed on the inner wall of the movable cavity 16, and a movable plate 18 is hinged on the end of the movable connecting member 17, and the top inner wall of the shrinkage groove 12 is fixedly connected to the top of a column 19, and a return spring 20 is fixedly connected between the bottom end of the column 19 and the inner wall of the movable plate 18.

[0025] Furthermore, the labeling frame 6 is arranged in an inverted concave shape, and two groups of movable blocks 7 are arranged, and the two groups of movable blocks 7 are mirror-imaged on the left and right sides of the central axis of the labeling frame 6. At the same time, a transmission part is arranged at one end of the transmission roller 8 away from the movable block 7, and the transmission part is transmission-connected to the output end of the stepper motor fixedly mounted on the outer wall of the back of the labeling frame 6, so that when the stepper motor is started, the transmission roller 8 is driven to rotate, so that the two groups of transmission rollers 8 arranged on the inner side of the labeling frame 6 can rotate, and the two groups of transmission rollers 8 serve as label storage rollers and label winding rollers respectively, so that when the transmission roller 8 rotates, a taut label belt is formed at the bottom position of the labeling frame 6, so that when the hydraulic cylinder 3 is started, it cooperates with the telescopic transmission member 4 to drive the labeling seat 5 to move downward, thereby driving the label on the label belt to be pressed downward and pressed tightly against the barrel mouth of the bottled water, thereby realizing the labeling of drinking water.

[0026] Specifically, a circular cavity having a size matching that of the contact block 9 is provided on the inner wall at the bottom of the labeling seat 5, and the contact block 9 is arranged inside the circular cavity. When the hydraulic cylinder 3 drives the telescopic transmission member 4 to drive the labeling seat 5 to move downward, so that the contact block 9 contacts the mouth of the barrel of the bottled water, due to the reverse force on the contact block 9, under the restriction and guidance of the convex ball 10 and the spiral slide groove 11, the contact block 9 will rotate on the inner wall of the labeling seat 5 while maintaining upward movement. In addition, the number of the contraction grooves 12 is set to six groups, and the six groups of contraction grooves 12 are evenly distributed in a circular array on the contact block 9. At the same time, the side plate 13 and the movable plate 18 are respectively arranged at the two ends of the contraction groove 12. Specifically, the side plate 13 is arranged on the side of the contraction groove 12 away from the center of the contact block 9, so that the contact roller 15 is arranged at an angle at the bottom position of the contact block 9, and the contact roller 15 is low on the side close to the center of the contact block 9 and high on the side away from the contact block 9, so that when the contact block 9 contacts the barrel mouth of the bottled water, it can contact the label and the barrel mouth of the bottled water in advance to squeeze the label from the inside to the outside, which can better discharge the air between the label and the barrel mouth, so that the label can be more tightly pasted.

[0027] At the same time, the movable cavity 16 is adapted to the movable connecting piece 17, and the length of the movable cavity 16 is greater than the length of the movable connecting piece 17, so that when the left end of the contact roller 15 moves upward, the movable connecting piece 17 will not interfere with the deflection of the contact roller 15, thereby ensuring that the contact roller 15 can be normally stored. In addition, a rectangular groove whose size is adapted to the column 19 is opened on the top inner wall of the movable plate 18, and the column 19 is arranged in the rectangular groove, so that under the elastic force of the return spring 20, the movable plate 18 is in a state of extending out of the contraction groove 12 in the initial state, so as to keep the contact roller 15 in an inclined state when not subjected to external force, so that it can be matched with a label to overcome the problem that the label on the top barrel mouth of the bottled water is restricted by the notch and cannot be stably pasted.

[0028] In an embodiment of the utility model, a contact belt 21 is provided on the arc-shaped outer wall of the contact roller 15, and the contact belt 21 is spirally arranged, so that when the contact roller 15 rotates along with the contact block 9, the contact roller 15 squeezes the label on the barrel mouth, and the spirally arranged contact belt 21 can continuously form a flattening action on the label from the inside to the outside, so that the label can be pasted more smoothly, thereby ensuring the label pasting effect of drinking water.

[0029] In the present invention, when in use, the external transmission equipment transports the bottled water to the bottom of the mounting plate 2. At this time, the stepper motor arranged on the side of the labeling frame 6 is started to drive the transmission roller 8 to rotate, so that the two sets of transmission rollers 8 arranged on the inner side of the labeling frame 6 can rotate, and then a tight label belt is formed at the bottom position of the labeling frame 6. At this time, the hydraulic cylinder 3 is started, and the telescopic transmission member 4 is cooperated to drive the labeling seat 5 to move downward, thereby driving the label on the label belt to press downward and adhere to the barrel mouth position of the bottled water, thereby realizing the labeling process of drinking water. At the same time, by providing a rolling mechanism, in cooperation with the guidance and restriction of the convex ball 10 and the spiral slide groove 11, the contact block 9 will keep moving upward while rotating on the inner wall of the labeling seat 5, and through the inclined contact roller 15, when the contact block 9 contacts the barrel mouth of the bottled water, it can contact the label and the barrel mouth of the bottled water in advance to squeeze the label from the inside to the outside, which can better discharge the air between the label and the barrel mouth, and then the contact roller 15 can cooperate with the label to overcome the problem that the label on the top barrel mouth of the bottled water is restricted by the notch and cannot be stably pasted.
