DETAILED DESCRIPTION

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

[0027] Example: See Figure 1-9The utility model provides a technical solution: a tablet back-sealing packaging machine, comprising a body 1, a longitudinal sealing structure 2 is arranged on the front of the body 1, a telescopic slot 3 is opened on the front of the body 1, a plurality of first telescopic rods 4 are arranged in the inner cavity of the telescopic slot 3, one end of the first telescopic rod 4 is connected to the second telescopic rod 5, a fixed block 6 is arranged between the two second telescopic rods 5, one end of the second telescopic rod 5 is connected to a push-pull block 7, a heating plate 8 is arranged on the back of the push-pull block 7 and the front of the fixed block 6, a cutting knife 9 is arranged above the push-pull block 7, a cutting slot 10 is opened on the front of the fixed block 6, and a grinding block 11 is arranged in the inner cavity of the cutting slot 10.

[0028] The cutting blade 9 and the grinding block 11 are on the same horizontal line.

[0029] In this embodiment, the packaging bag continues to move downward after being longitudinally sealed by the longitudinal sealing structure 2. When the packaging bag is located between the fixed block 6 and the push-pull block 7, the second telescopic rod 5 is started and drives the push-pull block 7 to approach the side of the fixed block 6. When the back of the push-pull block 7 is in contact with the front of the fixed block 6, the packaging bag can be clamped. At this time, the first telescopic rod 5 is started and drives the second telescopic rod 5 to move downward, thereby pulling the packaging bag down to facilitate the next segmentation work. When the fixed block 6 and the push-pull block 7 clamp the packaging bag, the heating plate 8 is started to perform transverse sealing on the packaging bag. At this time, the cutting knife 9 is inserted into the inner cavity of the grinding block 11 to cut and segment the packaging bag. The grinding block 11 uses abrasives such as diamond. When the cutting knife 9 is inserted into the grinding block 11, the cutting knife 9 can be polished by the grinding block 11, so that the cutting knife 9 can always remain sharp, making the incision of the packaging bag smoother, avoiding adhesion at the segmentation, and improving the practicality of the device.

[0030] Among them, a pillar 12 is arranged on the top of the body 1, one end of the pillar 12 is connected to the bottom plate 13, a material box 14 is arranged on the top of the bottom plate 13, a mounting frame 15 is connected to the top of the material box 14, a motor 16 is arranged in the inner cavity of the mounting frame 15, a rotating rod 17 is connected to the output end of the motor 16, and a discharge groove 23 is opened through the top of the material box 14.

[0031] One end of the rotating rod 17 is connected to a rotating disk 18 , and a plurality of discharge holes 22 are distributed in an annular manner on the rotating disk 18 . A connecting pipe 27 is provided at one end of the discharge trough 23 , and one end of the connecting pipe 27 is connected to a feed pipe 28 .

[0032] In this embodiment, after the material is put into the inner cavity of the material box 14, it is distributed above the turntable 18. After the motor 16 is started, the turntable 18 is driven to rotate through the rotating rod 17. When the discharge hole 22 rotates to the top of the discharge trough 23, the material can enter the discharge trough 23 through the discharge hole 22, and enter the inner cavity of the connecting pipe 27 through the discharge trough 23, and then enter the feed pipe 28 through the connecting pipe 7, thereby completing the continuous delivery of the material.

[0033] The support 12 is V-shaped, the outer ring of the rotating rod 17 is provided with a sleeve 19, the outer ring of the sleeve 19 is provided with a baffle 20 and a partition 21, the baffle 20 and the partition 21 are vertically distributed, and the heights of the baffle 20 and the partition 21 are inconsistent.

[0034] In this embodiment, refer to Figure 2 , three , it can be seen that the material box 14 is arranged above the body 1 in an inclined shape. Under the influence of gravity, the material in the inner cavity of the material box 14 will slide to the side away from the discharge groove 23, avoiding the discharge groove 23 from discharging excess material to improve the discharge accuracy; the turntable 18 rotates from the partition 21 to the baffle 20, and there is a certain gap between the partition 21 and the turntable 18. The gap is slightly larger than the actual thickness of the material, ensuring that the material can enter between the partition 21 and the baffle 20 in a horizontal state; the baffle 20 is used to limit the material to avoid the excess material being driven by the turntable 18 to the top of the discharge groove 23; when the discharge hole 22 rotates to between the partition 21 and the baffle 20, a single material will be stuck in the discharge hole 22, and then when the discharge hole 22 rotates to the top of the discharge groove 23, the material can be discharged through the discharge groove 23, so that the material weight in each section of the packaging bag can be kept consistent, so as to improve the qualified rate of the product and make the device more practical.

[0035] The inner cavity of the discharge hole 22 is threadedly connected with a sealing block 24 , an arc-shaped groove 25 is formed on the top of the sealing block 24 , and a fixing plate 26 is provided in the inner cavity of the arc-shaped groove 25 .

[0036] In this embodiment, refer to Figure 8 There are six discharge holes 22 on the same horizontal line. After the sealing block 24 is connected to the inner cavity of the discharge hole 22 by threading, a single discharge hole 22 can be closed, so that the device can easily adjust the material weight in each packaging bag segment, making the device more practical; the fixing plate 26 can facilitate the rotation of the sealing block 24, improving the convenience of the device.
