Description

Technical Field

[0001] The utility model relates to the technical field of nut packaging, and particularly relates to a labeling machine for nut packaging bags. Background Art

[0002] Most nuts are brittle and hard in texture, and are easily broken by external physical actions such as extrusion and collision during transportation, handling and storage. For example, almonds, pistachios, etc. Once subjected to greater pressure, the kernels will break into small pieces, affecting their appearance and eating experience. Packaging can provide a relatively stable space for nuts, reduce the direct impact of external forces on nuts, and at the same time has various advantages such as moisture-proof, insect-proof, and anti-oxidation. In order to brand and introduce product information, labeling operations are often carried out on nut packages.

[0003] In the prior art, nut packages are usually labeled by a labeling machine, which includes various operations such as product transportation, label feeding, label separation, and labeling actions. However, due to the irregular shapes of most nuts, after being placed in packages, the surface for labeling will be uneven, which makes the labels easily come off after labeling. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a labeling machine for nut packaging bags that overcomes the above technical problems or at least partially solves the above problems.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a labeling machine for nut packaging bags, including a main body and a conveyor belt,

[0007] A pressing mechanism, the pressing mechanism includes,

[0008] A slide rail, the slide rail is fixedly installed on the front side of the main body;

[0014] A ball, the ball is rotatably installed at the bottom of the slide bar;

[0015] A reciprocating mechanism is provided on the front side of the main body and is used to drive the pressing rod to move downward.

[0016] In a preferred embodiment, the reciprocating mechanism includes

[0017] a mounting block which is fixedly installed on the front side of the main body;

[0018] a reciprocating rod which is slidably sleeved inside the mounting block;

[0019] a transmission frame which is fixedly installed at the bottom of the reciprocating rod.

[0020] In a preferred embodiment, a limiting block is fixedly installed on the front side of the inner wall of the slide rail. A first spring is fixedly installed on the left side of the limiting block, and the other end of the first spring is fixedly connected to the right side of the carriage.

[0021] In a preferred embodiment, a bearing plate is fixedly installed at the top of the pressing rod. The bearing plate and the transmission frame are arranged in a staggered manner. A connecting rod is slidably sleeved inside the carriage. A driving plate is fixedly installed at the bottom of the connecting rod, and a deflecting shaft is fixedly installed at the rear side of the driving plate.

[0022] In a preferred embodiment, a mounting plate is fixedly installed on the front side of the main body through bolts. A deflecting groove is formed on the front side of the mounting plate. The shape of the deflecting groove is an inclined straight groove opening, and the deflecting shaft is slidably sleeved inside the deflecting groove.

[0023] In a preferred embodiment, a second spring is fixedly installed at the bottom of the carriage, and the other end of the second spring is fixedly connected to the top of the pressing plate.

[0026] The nut packaging bag labeling machine provided by the present utility model has the following beneficial effects:

[0027] 1. By providing a pressing mechanism, the pressing rod moves downward on the carriage, driving the pressing plate to move downward, so that the ball contacts the label. Since there are multiple limiting shells, sliding rods, third springs and balls, when facing the uneven surface of the packaging bag due to nuts, compared with the existing planar pressing, the dot-shaped pressing can make the label stick to the packaging bag more tightly in a more targeted manner.

[0028] 2. By setting up a reciprocating mechanism, starting the motor causes the rotating rod to rotate, thereby driving the transmission shaft to rotate. Since a straight notch that penetrates through the front and back is provided on the transmission frame, and the transmission shaft is slidably sleeved inside the straight notch, when the transmission shaft rotates, it squeezes the inner wall of the straight notch. Also, because the reciprocating rod is slidably sleeved inside the mounting block in the vertical direction, the transmission frame can only perform reciprocating movement in the vertical direction, thereby providing a driving force for the downward movement of the bearing plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0037] Referring to Figures 1-5 , the present utility model provides a technical solution: a nut packaging bag labeling machine, including a main body 1 and a conveyor belt 2. The pressing mechanism includes a slide rail 3, a carriage 4, a pressing rod 5, a pressing plate 6, a limiting shell 7, a slide rod 8, and a ball 9. The slide rail 3 is fixedly installed on the front side of the main body 1. The carriage 4 is slidably installed inside the slide rail 3. The pressing rod 5 is slidably sleeved inside the carriage 4. The pressing plate 6 is fixedly installed at the bottom of the pressing rod 5. The limiting shell 7 is fixedly installed at the bottom of the pressing plate 6. The slide rod 8 is slidably sleeved inside the limiting shell 7. The ball 9 is rotatably installed at the bottom of the slide rod 8. A reciprocating mechanism is arranged on the front side of the main body 1 for driving the pressing rod 5 to move downward. A third spring 22 is fixedly installed at the top of the slide rod 8, and the other end of the third spring 22 is fixedly connected to the top of the inner wall of the limiting shell 7. By setting the pressing mechanism, the packaged nuts are transported on the conveyor belt 2, and the labeling system provided on the main body 1 labels the top of the packaging bag. After that, when it is transported to a designated position through the conveyor belt 2, the pressing rod 5 moves downward on the carriage 4, driving the pressing plate 6 to move downward, so that the ball 9 contacts the label. Since there are multiple limiting shells 7, slide rods 8, third springs 22, and balls 9, when facing the uneven surface of the packaging bag due to the nuts, compared with the existing planar pressing, the dot-shaped pressing can make the label stick to the packaging bag more tightly in a more targeted manner. The setting of the third spring 22 enables the pressing plate 6 to continue to move downward to drive other balls 9 to press when one ball 9 cannot move downward due to extrusion. The limiting shell 7 limits the moving stroke of the slide rod 8 and the ball 9;

[0038] Referring to Figures 1-5, The reciprocating mechanism includes a mounting block 10, a reciprocating rod 11 and a transmission frame 12. The mounting block 10 is fixedly installed on the front side of the main body 1. The reciprocating rod 11 is slidably sleeved inside the mounting block 10. The transmission frame 12 is fixedly installed at the bottom of the reciprocating rod 11. A rotating rod 23 is rotatably installed on the front side of the main body 1. A transmission shaft 24 is fixedly installed on the front side of the rotating rod 23. The transmission shaft 24 is slidably sleeved inside the transmission frame 12. By setting the reciprocating mechanism, a motor is installed on the rear side of the main body 1. The output end of the motor is fixedly connected to the rear side of the rotating rod 23. By starting the motor, the rotating rod 23 rotates, thereby driving the transmission shaft 24 to rotate. Since a through straight groove is formed in the transmission frame 12 in the front-rear direction and the transmission shaft 24 is slidably sleeved inside the straight groove, the inner wall of the straight groove is squeezed when the transmission shaft 24 rotates. Also, because the reciprocating rod 11 is slidably sleeved inside the mounting block 10 in the vertical direction, the transmission frame 12 can only move reciprocally in the vertical direction, thereby providing a driving force for the downward movement of the bearing plate 15;

[0039] Refer to Figures 1-5 , A limiting block 13 is fixedly installed on the front side of the inner wall of the slide rail 3. A first spring 14 is fixedly installed on the left side of the limiting block 13. The other end of the first spring 14 is fixedly connected to the right side of the carriage 4. By setting the first spring 14, after the carriage 4 moves to a specified position and presses the packaging bag, it can return to its original position by the resilience of the first spring 14;

[0040] Refer to Figures 1-5, a bearing plate 15 is fixedly installed at the top of the pressing rod 5. The bearing plate 15 and the transmission frame 12 are arranged alternately. A connecting rod 16 is slidably sleeved inside the carriage 4. A driving plate 17 is fixedly installed at the bottom of the connecting rod 16. A deflecting shaft 18 is fixedly installed at the rear side of the driving plate 17. An installation plate 19 is fixedly installed at the front side of the main body 1 through bolts. A deflecting groove 20 is formed at the front side of the installation plate 19. The shape of the deflecting groove 20 is set as an inclined straight groove opening. The deflecting shaft 18 is slidably sleeved inside the deflecting groove 20. A second spring 21 is fixedly installed at the bottom of the carriage 4. The other end of the second spring 21 is fixedly connected to the top of the pressing plate 6. By setting the driving plate 17, in the initial state, the bearing plate 15 and the transmission frame 12 are staggered in the vertical direction. After the packaging bag is transported to the designated position on the conveyor belt 2, it presses the driving plate 17, causing the driving plate 17 to move to the right. Thus, through the connecting rod 16, the carriage 4 drives the pressing mechanism to move to the right. At the same time, because the deflecting groove 20 is set to be inclined, the deflecting shaft 18 is squeezed by the inner wall of the deflecting groove 20, causing the driving plate 17 to move upward at the same time until the bearing plate 15 moves below the transmission frame 12. Since the height of the top of the bearing plate 15 is higher than the height of the bottom of the transmission frame 12, when the transmission shaft 24 drives the transmission frame 12 to move downward, it presses the bearing plate 15, causing the ball 9 to press the label. After the transmission shaft 24 drives the transmission frame 12 to move upward, the packaging bag drives the driving plate 17 to continue to move until the driving plate 17 rises to a certain height, allowing the packaging bag to pass through. At this time, through the resilience of the first spring 14, the second spring 21 and the third spring 22, the pressing mechanism returns to its original position, waiting to press the next packaging bag, thereby making the pressing of the packaging bag more accurate. Compared with the existing reciprocating pressing through timing, it avoids the problem that the pressing timing is not accurate enough due to various factors such as the friction between the packaging bag and the conveyor belt 2.

[0041] Specifically, the working process or principle of this nut packaging bag labeling machine is as follows: When in use, the packaged nuts are transported on the conveyor belt 2, and labeling is performed on the top of the packaging bag through the labeling system provided on the main body 1. After the packaging bag is transported to the designated position on the conveyor belt 2, it squeezes the driving plate 17, causing the driving plate 17 to move to the right. Thus, through the connecting rod 16, the carriage 4 drives the pressing mechanism to move to the right. At the same time, since the deflection groove 20 is set to be inclined, the deflection shaft 18 is squeezed by the inner wall of the deflection groove 20, causing the driving plate 17 to move upward simultaneously until the bearing plate 15 moves below the transmission frame 12. A motor is installed at the rear side of the main body 1, and the output end of the motor is fixedly connected to the rear side of the rotating rod 23. By starting the motor, the rotating rod 23 rotates, thereby driving the transmission shaft 24 to rotate. Since a through straight groove is provided on the transmission frame 12, and the transmission shaft 24 is slidably sleeved inside the straight groove, when the transmission shaft 24 rotates, it squeezes the inner wall of the straight groove. Also, since the reciprocating rod 11 is slidably sleeved inside the mounting block 10 in the vertical direction, the transmission frame 12 can only perform reciprocating movement in the vertical direction. Since the height of the top of the bearing plate 15 is higher than the height of the bottom of the transmission frame 12, when the transmission shaft 24 drives the transmission frame 12 to move downward, it presses the bearing plate 15, driving the pressing plate 6 to move downward, making the ball 9 contact the label. Since there are multiple limiting shells 7, sliding rods 8, third springs 22 and balls 9, when facing the uneven surface of the packaging bag due to the nuts, compared with the existing planar pressing, the dot-shaped pressing can make the adhesion between the label and the packaging bag more tight in a more targeted manner. When the transmission shaft 24 drives the transmission frame 12 to move upward, the packaging bag drives the driving plate 17 to continue moving until the driving plate 17 rises to a certain height, allowing the packaging bag to pass through. At this time, through the resilience of the first spring 14, the second spring 21 and the third spring 22, the pressing mechanism returns to its original position, waiting to press the next packaging bag.
