Description

Technical Field

[0001] The invention relates to disposable tableware packaging equipment, in particular to a tableware packaging machine. Background Art

[0002] The disposable tableware comprises a packaging bag, disposable chopsticks and paper towels arranged in the packaging bag.

[0003] like Figure 1 As shown, an existing disposable tableware packaging machine includes a frame 1, on which are arranged, in order of production, a paper folding mechanism 2, a first conveying part 3, and a packaging mechanism 5, wherein the first conveying part 3 is provided with a chopstick supply machine 4.

[0004] The first conveyor belt 31 is installed on the frame 1 , and the vertical height of the first conveyor belt 31 is lower than the height of the frame 1 . The chopstick feeder 4 is installed on the frame 1 on both sides of the first conveyor belt 31 .

[0005] The paper folding mechanism 2 folds and cuts the paper strip into a rectangular paper towel. The paper towel 6 enters the first conveyor belt 31 of the first conveying part 3, and the first conveyor belt 31 transports the paper towel 6 to the packaging machine 52.

[0006] The chopstick supply machine 4 includes a replenishment port 41 and a supply port 42, wherein the supply port 42 extends above the first conveyor belt 31. When the paper towel 6 passes through the supply port 42, a pair of table chopsticks 7 is supplied from the supply port 42 to the first conveyor belt 31. Then the table chopsticks 7 and the paper towel 6 are transported to the packaging mechanism 5 for packaging.

[0007] The packaging mechanism 5 includes a second conveyor belt 51 and a packaging machine 52 disposed on the conveyor belt 51 .

[0008] A packaging bag roller 54 is provided below the second conveyor belt 51. A packaging bag is placed on the packaging bag roller 54. The packaging bag is in the shape of a strip. The second conveyor belt 51 is attached to the packaging bag roller 54 and moves from below the second conveyor belt 51 to above the second conveyor belt 51. The two sides of the strip packaging bag are close to each other during the movement until they are bonded at the packaging machine 52. After bonding, the packaging bag is in the shape of a tube. Each chopstick and paper towel are evenly distributed in a group in the tube-shaped packaging bag. The packaging machine 52 is provided with a hot pressing device. The hot pressing device is pressed down at regular intervals to divide the tube-shaped packaging bag into several sections of independent packaging. Each package contains a pair of chopsticks and a paper towel. The finished product flows out from the finished product outlet 53 of the second conveyor belt 51.

[0009] Since the second conveyor belt 51 plays a supporting role, the horizontal height of the second conveyor belt 51 is lower than the first conveyor belt 31 . When the chopsticks 7 and the paper towel 6 are separated from the first conveyor belt 31 , they directly fall onto the second conveyor belt 31 .

[0010] According to different production requirements, when it is necessary to improve production efficiency and increase the transport speed of the first conveyor belt 31, the chopsticks 7 and paper towels 6 continue to move along the original direction of movement after leaving the first conveyor belt 31 due to inertia, and at the same time fall down to the second conveyor belt 51.

[0011] After falling onto the second conveyor belt 51 , the paper towel 6 will remain at the landing point. Due to the large inertia of the chopsticks 7 , they will continue to move forward relative to the second conveyor belt 51 , that is, a position difference is formed between the chopsticks 7 and the paper towel 6 on the second conveyor belt 51 .

[0012] Therefore, as the packaging speed increases, the position difference between the table chopsticks 7 and the paper towels 6 on the second conveyor belt 51 will become larger and larger. The larger the position difference, the more it affects the packing of the table chopsticks and paper towels together. Therefore, there is a limit speed for the packing speed of the tableware packing machine. When the conveying speed exceeds the limit speed, the position difference between the table chopsticks and paper towels is too large, and they cannot be packed uniformly, resulting in defective products. Summary of the invention

[0013] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a tableware packaging machine, which increases the resistance of chopsticks on the second conveyor belt and reduces the position difference between chopsticks and paper towels, thereby improving the maximum speed of the tableware packaging machine during packaging.

[0014] In order to solve the above technical problems, the present invention provides a tableware packaging machine, including a frame, a paper folding mechanism arranged on the frame in sequence, a first conveying part, a packaging mechanism, and a chopstick feeder arranged on the first conveying part, the packaging mechanism includes a packaging machine and a second conveyor belt for receiving tableware, the second conveyor belt is arranged at an angle, and the height of one end of the second conveyor belt close to the first conveyor belt is lower than that of one end of the second conveyor belt close to the finished product outlet.

[0015] Technical effect: The second conveyor belt, which is set at an angle, acts as a barrier. Before the chopsticks land on the second conveyor belt, the chopsticks are blocked from moving forward, preventing them from directly rushing into the working range of the packaging machine. When the chopsticks land on the second conveyor belt, the second conveyor belt, which is set at an angle, increases the resistance to the chopsticks' movement, making it difficult for the chopsticks to continue sliding forward along the second conveyor belt after they land on the second conveyor belt. This reduces the position difference between the chopsticks and the paper towels, allowing the packaging machine to further increase its production speed.

[0016] The technical solution further defined in the present invention is that a difference angle is formed between the surface of the second conveyor belt facing the packaging bag roller and the horizontal plane, and the difference angle does not exceed 30°.

[0017] The present invention is further configured such that the first conveyor belt is arranged obliquely toward the supply port, and conveying baffles extend from both sides of the first conveyor belt.

[0018] The present invention is further configured such that a plurality of support rollers for supporting the tablets are arranged on the supply port.

[0019] The present invention is further configured such that an infrared counter is provided on the other side of the frame corresponding to the chopstick feeder, and a yield hole is provided on the pressing sheet directly facing the output end of the infrared counter.

[0020] The present invention is further configured such that a bracket for fixing the infrared counter is provided on the frame, and an output end of the infrared counter is tilted to face the path through which the paper towel passes.

[0021] The present invention is further configured such that adjacent support rollers have different heights so that the longitudinal sections of the support rollers are arranged along a parabolic direction. When the pressing sheet crosses the first conveyor belt and rests on the support rollers, the pressing sheet is recessed toward the first conveyor belt to form an arc surface facing the first conveyor belt.

[0022] The present invention is further configured such that the pressing sheet is made of plastic or rubber.

[0023] The beneficial effects of the present invention are:

[0024] (1) The chopsticks of the present invention block the forward movement of the chopsticks and increase the resistance of the chopsticks to sliding relative to the second conveyor belt, so that the chopsticks can maintain a relatively matching position with the paper towels at a higher conveying speed, which is convenient for packaging.

[0025] (2) Compared with the prior art, the present invention is equivalent to rotating the other end of the first conveyor belt upward at a certain angle with one end close to the first conveyor belt as the center, so that the side originally attached to the strip packaging bag is separated from the strip packaging bag, reducing the force on the strip packaging bag during the transmission process, and the strip packaging bag is not easily damaged.

[0026] (3) In the present invention, the chopsticks and paper towels are on the first conveyor belt. Due to the inclination of the first conveyor belt, the chopsticks are located on one side of the paper towels. Due to the inclination of the second conveyor belt, the displacement of the chopsticks relative to the paper towels is limited to a certain range, thereby reducing the impact on packaging.

[0041] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0042] Embodiment 1:

[0043] A tableware packaging machine comprises a frame 1, a paper folding mechanism 2, a first conveyor 3, a packaging mechanism 5 and a chopstick feeder 4 arranged on the first conveyor 3 in sequence, the packaging mechanism 5 comprises a packaging machine 52 and a second conveyor belt 51 for receiving tableware, the second conveyor belt 51 is arranged at an angle, and the height of the second conveyor belt 51 near the first conveyor belt 31 is lower than the height of the second conveyor belt 51 near the finished product outlet 53.

[0044] The second conveyor belt 51., which is set obliquely, acts as a barrier. Before the chopsticks 7 land on the second conveyor belt 51., the chopsticks 7 are blocked from moving forward, preventing them from directly rushing into the working range of the packaging machine. When the chopsticks 7 land on the second conveyor belt 51., the second conveyor belt 51., which is set obliquely, increases the resistance to the movement of the chopsticks 7, making it difficult for the chopsticks 7 to continue to slide forward along the second conveyor belt 51. after they land on the second conveyor belt 51. This reduces the position difference between the chopsticks 7 and the paper towels 6, allowing the packaging machine to further increase the production speed.

[0045] The second conveyor belt 51 has a difference angle with the horizontal plane, which is not more than 30°. The first conveyor belt 31 is tilted toward the supply port 42, and conveying baffles 32 extend from both sides of the first conveyor belt 31. The supply port 42 is provided with a plurality of support rollers 34 for supporting the pressing sheet 33. The frame 1 is provided with an infrared counter 35 on the other side of the chopstick feeder 4, and a clearance hole 36 is provided on the pressing sheet 33 at the output end facing the infrared counter 35.

[0046] The frame 1 is provided with a bracket for fixing the infrared counter 35, and the output end of the infrared counter 35 is tilted to face the path of the paper towel 6. The heights of adjacent support rollers 34 are different, so that the longitudinal sections of the support rollers 34 are arranged along the parabolic direction. When the pressing sheet 33 is placed on the support roller 34 across the first conveyor belt 31, the pressing sheet 33 is concave toward the first conveyor belt 31 to form an arc surface facing the first conveyor belt 31. The pressing sheet 33 is made of plastic or rubber.

[0047] Among them, the chopsticks 7 block the forward movement of the chopsticks 7 and increase the resistance of the chopsticks 7 to sliding relative to the second conveyor belt 51, so that the chopsticks 7 can maintain a relatively matching position with the paper towel 6 at a higher conveying speed, which is convenient for packaging. Compared with the prior art, it is equivalent to taking one end close to the first conveyor belt 31 as the center and rotating the other end upward by a certain angle, so that the side originally attached to the strip packaging bag is separated from the strip packaging bag, reducing the force on the strip packaging bag during the conveying process, and the strip packaging bag is not easily damaged. The chopsticks 7 and the paper towel 6 are on the first conveyor belt 31. Due to the tilting effect of the first conveyor belt 31, the chopsticks 7 are located on one side of the paper towel 6. Due to the tilting effect of the second conveyor belt 51, the displacement of the chopsticks 7 relative to the paper towel 6 is limited to a certain range, reducing the impact on packaging.

[0048] Embodiment 2:

[0049] The tableware packaging machine provided in this embodiment has a structure as shown in the figure.

[0050] The tableware packaging machine includes a frame 1, a paper folding mechanism 2, a first conveying part 3, a packaging mechanism 5, and a chopstick feeder 4 provided on the first conveying part 3 in sequence. The first conveying part 3 includes a first conveyor belt 31. The supply port 42 of the chopstick feeder 4 extends to above the first conveyor belt 31. A pressing sheet 33 is provided on the frame 1. The pressing sheet 33 spans the first conveyor belt 31. One end of the pressing sheet 33 is fixed on the frame 1, and the other end spans the first conveyor belt 31 and is placed on the supply port 42.

[0051] The pressing sheet 33 in this solution prevents the chopsticks 7 from being ejected from the first conveyor belt 31, thereby reducing the generation of incomplete and defective products.

[0052] The first conveyor belt 31 is tilted toward the supply port 42. Conveying baffles 32 extend from both sides of the conveyor belt. The supply port 42 is provided with a plurality of supporting rollers 34 for supporting the pressing sheet 33. An infrared counter 35 is provided on the other side of the frame 1 corresponding to the chopstick supply machine 4, and a clearance hole 36 is provided on the pressing sheet 33 at the output end facing the infrared counter 35. A bracket for fixing the infrared counter 35 is provided on the frame 1, and the output end of the infrared counter 35 is tilted to face the path through which the paper towel 6 passes.

[0053] The adjacent support rollers 34 have different heights, so that the longitudinal sections of the support rollers 34 are arranged along a parabola direction, and when the pressing sheet 33 is placed on the support rollers 34 across the first conveyor belt 31, the pressing sheet 33 is recessed toward the first conveyor belt 31 to form an arc surface facing the first conveyor belt 31. The pressing sheet 33 is made of plastic or rubber.

[0054] When the chopsticks 7 fall onto the first conveyor belt 31, they bounce up and hit the pressing sheet 33 before falling onto the first conveyor belt 31. Since the first conveyor belt 31 is tilted and the cross section of the chopsticks 7 is circular, the chopsticks 7 will automatically roll to the side of the first conveyor belt 31 during transportation until they reach the conveying baffle 32. This allows the chopsticks 7 to be automatically straightened before packaging.

[0055] Since the first conveyor belt 31 is arranged at an angle, the chopsticks 7 are tilted and bounced up when they first contact the first conveyor belt 31 , thereby reducing the bounce height in the vertical direction and making it difficult for them to bounce out of the first conveyor belt 31 .

[0056] The material of the pressing sheet 33 should have a certain bending and deformation capability, that is, when the pressing sheet 33 is placed on the supporting roller 34, it can bend toward the first conveyor belt 31 to form an arc surface due to its own weight. When the chopsticks 7 bounce up, at least nine times out of ten they hit the arc surface, and the arc surface combined with the pressing sheet 33 itself forms a buffer for the chopsticks 7.

[0057] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
