Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, and in particular to a sealing machine for bagged food. Background Technology

[0002] A food sealing machine is a mechanical device that can be used for various food packaging. It can perform functions such as vacuuming, gas filling, heat sealing, coding / inkjet printing, and cutting of packaging bags, thereby improving packaging efficiency and quality.

[0003] In the prior art, when food bags are sealed by a sealing machine on a conveyor, the conveyor lacks a limiting mechanism for the food bags, which makes the food bags prone to shifting and ultimately leads to sealing failure. Therefore, this utility model proposes a sealing machine for bagged food to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when food bags are sealed on the conveyor by the sealing machine, the conveyor lacks a limiting device for the food bags, which makes the food bags easy to deviate and ultimately leads to sealing failure. Therefore, this invention proposes a sealing machine for bagged food.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sealing machine for bagged food, including

[0007] Conveyor;

[0008] A sealing machine, which is rotatably connected to the top of a conveyor;

[0009] A fixing mechanism and a clamping mechanism, wherein the clamping mechanism cooperates with the fixing structure and the conveyor, respectively;

[0010] A limiting mechanism, comprising: two limiting rods, a connecting rod, and a drive frame;

[0011] Both limit rods are located at the top of the conveyor. The connecting rod is fixedly connected to the limit rod located on the right side, and the drive frame is fixedly connected to the limit rod located on the left side. The drive frame is slidably connected to the bottom of the conveyor, and the connecting rod is slidably connected to the top of the conveyor.

[0012] As a preferred embodiment of this utility model, the clamping mechanism includes: a rotating frame, a sliding block, a fixed rod, and a pulling rod;

[0013] The rotating frame is rotatably connected to the top of the drive frame. The rotating frame is rotatably connected to the sliding block, which is slidably connected to the front side of the conveyor. The sliding block is fixedly connected to the fixed rod, and the pulling rod is rotatably connected to the fixed rod and the connecting rod respectively.

[0014] As a preferred embodiment of this utility model, the fixing mechanism includes: a fixing frame, a torsion spring, a positioning plate, a positioning rod, a positioning spring, and a fixing block;

[0015] The fixed frame is fixedly installed at the bottom of the rotating frame, and the fixed frame passes through the drive frame. The top of the positioning plate passes through the rotating rod, and the top of the positioning plate is fixedly connected to the sliding block. The positioning rod is slidably connected to the rotating frame.

[0016] As a preferred embodiment of this utility model, a torsion spring is fixedly installed at the bottom of the drive frame, and the bottom end of the torsion spring is fixedly connected to the fixed frame.

[0017] As a preferred embodiment of this utility model, the positioning disk has multiple positioning slots arranged at equal intervals, and the left end of the positioning rod can be detachably engaged with the positioning slot.

[0018] In a preferred embodiment of this utility model, a positioning spring is fixedly installed on the right side of the positioning rod, and a fixing block is fixedly installed on the right side of the positioning spring. The fixing block is fixedly connected to the rotating rod.

[0019] Beneficial effects:

[0020] 1. After the rotating frame is rotated clockwise, the rotating frame can drive the sliding block to move to the right, so that the rotating rod can squeeze the driving frame to move to the right. Then the sliding block drives the fixed rod to move to the right. At this time, the fixed rod can pull the pulling rod, and the pulling rod can pull the connecting rod and the limit rod located on the right to move to the left. When the driving frame moves to the right, it will also directly drive the limit rod to move to the right, so that the two limit rods can move closer to each other to limit the various sizes of food packaging bags at the top of the conveyor.

[0021] 2. After the positioning rod engages with the positioning plate, the positioning rod can prevent the rotating frame from rotating on the sliding block, so that the rotating frame cannot control the movement of the sliding block, and the rotating frame cannot rotate on the driving frame. This allows the rotating frame to position the driving frame and the connecting rod, and thus position the two limiting rods, so that the two limiting rods can stably limit the food packaging bag.

[0022] In this invention, by unlocking the adjustment mechanism, the adjustment mechanism can control the limiting mechanism, allowing the two limiting rods in the limiting mechanism to move closer to each other, thereby simultaneously adjusting the distance between the two limiting rods. This allows the limiting rods to adapt to various food bags, continuously keeping the food bag in the middle of the conveyor and preventing sealing failure. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example

[0030] Reference Figure 1-Figure 4 A sealing machine for bagged food, including

[0031] Conveyor 1;

[0032] Sealing machine 2 is rotatably connected to the top of conveyor 1;

[0033] The fixing mechanism and the clamping mechanism are respectively coordinated with the fixing structure and the conveyor 1;

[0034] The limiting mechanism includes: two limiting rods 3, a connecting rod 4, and a drive frame 5;

[0035] Both limit rods 3 are located at the top of the conveyor 1. The connecting rod 4 is fixedly connected to the limit rod 3 located on the right side. The drive frame 5 is fixedly connected to the limit rod 3 located on the left side. The drive frame 5 is slidably connected to the bottom of the conveyor 1. The connecting rod 4 is slidably connected to the top of the conveyor 1.

[0036] With the above structure, by unlocking the adjustment mechanism, the adjustment mechanism can control the limiting mechanism, so that the two limiting rods 3 in the limiting mechanism can move closer to each other to adjust the distance between the two limiting rods 3 at the same time. This allows the limiting rods 3 to adapt to various food bags and keep the food bags in the middle of the conveyor 1 to avoid sealing failure.

[0037] As a preferred embodiment of this utility model, the clamping mechanism includes: a rotating frame 6, a sliding block 7, a fixed rod 8, and a pulling rod 9;

[0038] The rotating frame 6 is rotatably connected to the top of the drive frame 5. The rotating frame 6 is rotatably connected to the sliding block 7, which is slidably connected to the front side of the conveyor 1. The sliding block 7 is fixedly connected to the fixed rod 8. The pulling rod 9 is rotatably connected to the fixed rod 8 and the connecting rod 4 respectively. After the rotating frame 6 is rotated clockwise, the rotating frame 6 can drive the sliding block 7 to move to the right, so that the rotating rod can squeeze the drive frame 5 to move to the right. Then the sliding block 7 drives the fixed rod 8 to move to the right. At this time, the fixed rod 8 can pull the pulling rod 9. The pulling rod 9 then pulls the connecting rod 4 and the limiting rod 3 located on the right side to move to the left. When the drive frame 5 moves to the right, it will also directly drive the limiting rod 3 to move to the right, so that the two limiting rods 3 can move closer to each other to limit the various sizes of food packaging bags on the top of the conveyor 1.

[0039] As a preferred embodiment of this utility model, the fixing mechanism includes: a fixing frame 10, a torsion spring 11, a positioning plate 12, a positioning rod 13, a positioning spring 14, and a fixing block 15;

[0040] The fixed frame 10 is fixedly installed at the bottom of the rotating frame 6. The fixed frame 10 passes through the drive frame 5. The top of the positioning plate 12 passes through the rotating rod. The top of the positioning plate 12 is fixedly connected to the sliding block 7. The positioning rod 13 is slidably connected to the rotating frame 6. After the positioning rod 13 engages with the positioning plate 12, the positioning rod 13 can prevent the rotating frame 6 from rotating on the sliding block 7, so that the rotating frame 6 cannot control the movement of the sliding block 7, and the rotating frame 6 cannot rotate on the drive frame 5. This allows the rotating frame 6 to position the drive frame 5 and the connecting rod 4, and thus position the two limiting rods 3, so that the two limiting rods 3 can stably limit the food packaging bag.

[0041] As a preferred embodiment of this utility model, a torsion spring 11 is fixedly installed at the bottom of the drive frame 5. The bottom end of the torsion spring 11 is fixedly connected to the fixed frame 10. The torsion spring 11 is used to reset the position of the rotating frame 6, so that the rotating frame 6 can reset the position of the drive frame 5 and the connecting rod 4, and thus reset the position of the two limiting rods 3.

[0042] As a preferred embodiment of this utility model, the positioning plate 12 is provided with a plurality of positioning slots arranged at equal intervals. The left end of the positioning rod 13 can be detachably engaged with the positioning slot. After the positioning rod 13 is inserted into the inner side of the positioning slot, the positioning rod 13 can block the rotation of the rotating frame 6, thereby achieving the positioning of the rotating frame 6.

[0043] As a preferred embodiment of this utility model, a positioning spring 14 is fixedly installed on the right side of the positioning rod 13, and a fixing block 15 is fixedly installed on the right side of the positioning spring 14. The fixing block 15 is fixedly connected to the rotating rod. The positioning spring 14 is used to reset the position of the positioning rod 13, so that the positioning rod 13 can automatically position the rotating frame 6.

[0044] It should be noted that the specific models of sealing machine 2 and conveyor 1 used should be selected by those skilled in the art, and the above-mentioned sealing machine 2 and conveyor 1 are all existing technologies, which will not be elaborated on in this solution.

[0045] The working principle of this utility model is as follows: When sealing food packaging bags, first place the food packaging bags on top of conveyor 1, then adjust the distance between the two limiting rods 3, first push the positioning rod 13 to disengage from the positioning plate 12, unlock the rotating frame 6 and the sliding block 7, and then rotate the rotating frame 6. After the rotating frame 6 is rotated clockwise, the rotating frame 6 can drive the sliding block 7 to move to the right, so that the rotating rod can squeeze the driving frame 5 to move to the right. Then the sliding block 7 drives the fixed rod 8 to move to the right. At this time, the fixed rod 8 can pull the pulling rod 9, and the pulling rod 9 can then pull the connecting rod 4 and the limiting rod 3 located on the right side to move to the left. When the driving frame 5 moves to the right, it will also directly drive the limiting rod 3 to move to the right, so that the two limiting rods 3 can move closer to each other, thereby sealing the various large-sized bags on top of the conveyor 1. Small food packaging bags are limited. After the limiting is completed, the positioning rod 13 is released, so that the positioning rod 13 can automatically engage with the positioning plate 12. After the positioning rod 13 engages with the positioning plate 12, the positioning rod 13 can prevent the rotating frame 6 from rotating on the sliding block 7, so that the rotating frame 6 cannot control the movement of the sliding block 7, and the rotating frame 6 cannot rotate on the driving frame 5. This allows the rotating frame 6 to position the driving frame 5 and the connecting rod 4, and thus position the two limiting rods 3. This allows the two limiting rods 3 to stably limit the food packaging bag, so that the food packaging bag can continuously stay in the middle position of the conveyor 1. Then, the conveyor 1 is started again, and the conveyor 1 can move the food packaging bag to the far right. Then, the sealing machine 2 is started, and the sealing machine 2 falls in an arc to seal the food packaging bag on the far right, which is quick and convenient.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
