Description

Technical Field

[0001] This utility model belongs to the field of mushroom bag tying technology, and more specifically, it relates to an automatic bag tying machine. Background Technology

[0002] When cultivating edible fungi, the culture medium needs to be placed in a sealed mushroom bag to simulate the growth environment of the fungi. The bag is then opened for inoculation with the spawn during the cultivation process. To facilitate opening and sealing, the bag is usually sealed with a slipknot. To improve the production efficiency of slipknot bags, automated rope-tying equipment is now mainly used for processing.

[0003] For example, Chinese patent CN219857907U discloses a high-efficiency automatic rope-tying mushroom bag production machine, which mainly includes a frame with two symmetrically arranged automatic rope-tying devices inside the frame. The two sets of automatic rope-tying devices are connected to a drive mechanism. A quantitative mushroom bag cutting device is mounted on the frame to cooperate with the two sets of automatic rope-tying devices. Corresponding guide mechanisms are provided above the two sets of automatic rope-tying devices, and the guide mechanisms cooperate with a mushroom bag unwinding mechanism. This device, through the quantitative mushroom bag cutting device and the two sets of automatic rope-tying devices, achieves automatic adjustment of the length of empty mushroom bags, automatic knot tying, and automatic cutting of empty mushroom bags, resulting in high production efficiency.

[0004] However, the above-mentioned bag-tying machine still has the following problems in actual use: 1. The bag unwinding mechanism is set on the left and right sides of the machine frame, which results in a large space occupied on both sides of the machine, serious waste of workshop space, and the bag unwinding requires two turns, resulting in insufficient smoothness of movement; 2. The unwinding accuracy is not easy to control when the bag is unwinding, and the internal structure of the machine is relatively loose and the volume is large; 3. The size of the processed bags is fixed, and the versatility is poor. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic bag-tying machine, which is equipped with an adjustable movable frame. By adjusting the position of the movable frame, the size of the mushroom bags to be processed can be adjusted, realizing the processing of mushroom bags of various specifications and greatly improving the versatility of the equipment.

[0006] The automatic bag-tying machine includes a frame, on which at least one set of automatic bag-tying devices is provided. The automatic bag-tying devices include a bag unwinding mechanism, a guide wheel mechanism, a gripper mechanism, and a bag traction mechanism arranged sequentially from front to back. The bag unwinding mechanism, the guide wheel mechanism, and the gripper mechanism are fixedly connected to the frame, and the bag traction mechanism is slidably connected to the frame. A rope-tying mechanism is fixedly connected to the gripper mechanism, and a rope-winding manipulator is rotatably connected to the gripper mechanism. Below the gripper mechanism are a bag rope tightening mechanism and a bag rope cutting mechanism that cooperate with the rope-tying mechanism. A bag cutting mechanism is provided at the front end of the bag traction mechanism.

[0007] Preferably, the unwinding mechanism for the mushroom bags includes a fixed base, which is fixedly connected to the front end of the frame. An unwinding motor is fixedly connected to one side of the fixed base. The output end of the unwinding motor passes through the fixed base, and a roll for supporting the mushroom bag roll is fixedly connected to the output end of the unwinding motor. A baffle is fixedly connected to the roll. Unwinding guide wheel one and unwinding guide wheel two are rotatably connected to the upper and lower ends of the fixed base through brackets, respectively.

[0008] Preferably, the guide wheel mechanism includes a guide wheel group one and a guide wheel group two. The guide wheel group one cooperates with the mushroom bag unwinding mechanism, and the guide wheel group two cooperates with the gripper mechanism. The guide wheel group one includes a wheel frame one, on which two guide wheels one arranged vertically are rotatably connected. A closing plate is provided on the side of the wheel frame one near the guide wheel group two, and a channel one for the mushroom bag to pass through is provided in the closing plate.

[0009] Preferably, the guide wheel assembly two includes a wheel frame two, a support plate fixedly connected to the wheel frame two, an adjusting plate fixedly connected to both sides of the support plate, two cooperating guide wheels two rotatably connected to the side of the adjusting plate away from the support plate, a channel two for the passage of the mushroom bag being opened on the support plate and the adjusting plate, an arc-shaped hole being opened on the adjusting plate, an assembly hole cooperating with the arc-shaped hole being opened on the support plate, and a guide wheel three and a guide wheel four for guiding the mushroom bag being rotatably connected to the side of the wheel frame two away from the guide wheel two.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. An adjustable movable frame is added. By adjusting the position of the movable frame, the size of the mushroom bags to be processed can be adjusted, which changes the distance between the slip joint below the gripper mechanism and the bag rope cutting mechanism.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Example 1:

[0037] like Figures 1 to 16 As shown, the automatic bag-tying machine includes a frame 1, on which a set of automatic bag-tying devices are provided. The automatic bag-tying devices include a bag unwinding mechanism 10, a guide wheel mechanism, a gripper mechanism 7, and a bag traction mechanism 3 arranged sequentially from front to back. The bag unwinding mechanism 10, the guide wheel mechanism, and the gripper mechanism 7 are fixedly connected to the frame 1, and the bag traction mechanism 3 is slidably connected to the frame 1. A rope-tying mechanism 5 is fixedly connected to the gripper mechanism 7, and a rope-winding manipulator 12 is rotatably connected to the gripper mechanism 7. Below the gripper mechanism 7, there is a bag rope tensioning mechanism 11 and a bag rope cutting mechanism 13 that cooperate with the rope-tying mechanism 5. A bag cutting mechanism 4 is provided at the front end of the bag traction mechanism 3.

[0038] In this embodiment, the gripper mechanism 7, the rope-tying mechanism 5, the rope-winding robot 12, the bag rope tensioning mechanism 11, the bag rope cutting mechanism 13, the mushroom bag traction mechanism 3, and the mushroom bag cutting mechanism 4 are all existing technologies. Their structures and working principles are described in CN219857906U and CN219857907U, and will not be repeated here.

[0039] In this embodiment, the bag unwinding mechanism 10, guide wheel mechanism, gripper mechanism 7, and bag traction mechanism 3 are arranged sequentially from front to back. This ensures that the bag unwinding mechanism 10 does not occupy the space on the left and right sides of the bag tying machine. When the bag traction mechanism 3 pulls the bag, the bag conveying direction is the same as the material output direction of the bag unwinding mechanism 10, resulting in a smoother movement. Furthermore, the rope winding robot 12, bag rope tensioning mechanism 11, and bag rope cutting mechanism 13 have a compact structure, occupy little space, and cooperate more smoothly, thus improving the reliability of equipment operation.

[0040] Example 2:

[0041] The automatic bag-tying machine includes two sets of automatic bag-tying devices, which are symmetrically arranged on the frame 1.

[0042] like Figure 1 , Figure 15 and Figure 16 As shown, the mushroom bag unwinding mechanism 10 includes a fixed base 1001, which is fixedly connected to the front end of the frame 1. In the two sets of mushroom bag unwinding mechanisms 10, an unwinding motor 1002 is fixedly connected to the side of the fixed base 1001 that is far apart from each other. The output end of the unwinding motor 1002 passes through the fixed base 1001, and a roll 1006 for supporting the mushroom bag roll is fixedly connected to the output end of the unwinding motor 1002. A baffle 1003 is provided on the other side of the fixed base 1001. The baffle 1003 is fixedly connected to the end of the roll 1006 near the fixed base 1001. The baffle 1003 is used to block the mushroom bag roll and plays a supporting and limiting role on the side of the mushroom bag roll. The upper and lower ends of the fixed base 1001 are respectively rotatably connected to the unwinding guide wheel 1004 and the unwinding guide wheel 2 1005 via the bracket. The unwinding guide wheel 1004 and the unwinding guide wheel 2 1005 play a guiding role and are used to increase the discharge tension of the mushroom bag. In conjunction with the unwinding motor 1002, they can better control the unwinding accuracy of the mushroom bag.

[0043] like Figure 4 and Figure 5 As shown, the guide wheel mechanism includes guide wheel group 1 9 and guide wheel group 2 8. Guide wheel group 1 9 cooperates with the unwinding end of the mushroom bag unwinding mechanism 10, and guide wheel group 2 8 cooperates with the inwinding end of the gripper mechanism 7. In use, after the mushroom bag is unwound from the mushroom bag unwinding mechanism 10, it passes through guide wheel group 1 9 and guide wheel group 2 8 in sequence, and finally enters the gripper mechanism 7.

[0044] like Figure 11As shown, the guide wheel assembly 9 includes a wheel frame 901. The bottom of the wheel frame 901 is fixedly connected to the frame 1. Two guide wheels 902 are rotatably connected on the side of the wheel frame 901 near the mushroom bag unwinding mechanism 10. The mushroom bag passes through the gap between the two guide wheels 902. A closing plate 903 is provided on the side of the wheel frame 901 near the guide wheel assembly 8. The closing plate 903 has a channel 1 for the passage of the mushroom bag. The channel 1 corresponds to the gap mentioned above, and the closing plate 903 has a trapezoidal structure, that is, the bag outlet of the channel 1 gradually becomes smaller.

[0045] like Figure 10 As shown, the guide wheel assembly 8 includes a wheel frame 801. The bottom of the wheel frame 801 is fixedly connected to the frame 1. A support plate 805 is fixedly connected to the wheel frame 801. Adjusting discs 8021 are fixedly connected to both sides of the support plate 805. Specifically, the adjusting discs 8021 are provided with arc-shaped holes 8022. The support plate is provided with assembly holes that mate with the arc-shaped holes 8022. The support plate 805 is fixedly connected to the two adjusting discs 8021 by bolts. The two adjusting discs 8021 can be rotated and finely adjusted through the arc-shaped holes 8022. Two guide wheels 802 are rotatably connected to the side of the adjusting discs 8021 away from the support plate. Channels 2 for the passage of the mushroom bags are provided on the adjusting discs 8021 and the support plate 805. The gap between the channels 2 and the two guide wheels 802 corresponds to the gap between them. By rotating the two adjusting discs 8021 for fine-tuning, the guide wheels 802 on the two sets of adjusting discs 8021 can be arranged in an alternating direction along their axes. This allows the mushroom bags to be further tightened into a rope during transport, making it easier for them to enter the gripper mechanism 7.

[0046] The wheel frame 801 is rotatably connected to guide wheel 3 803 and guide wheel 4 804 on the side away from guide wheel 2 802. Guide wheel 4 804 is located diagonally below guide wheel 3 803. A guide shaft 806 is provided between guide wheel 3 803 and guide wheel 4 804. The guide shaft 806 plays an auxiliary guiding role, which facilitates the feeding of the mushroom bag into the gripper mechanism 7 along guide wheel 3 803 and guide wheel 4 804.

[0047] like Figure 6 As shown, a drive mechanism 6 is fixedly connected to the frame 1, and the drive mechanism 6 drives the rope-winding robot 12 to rotate. Specifically, the output end of the drive mechanism 6 is provided with a transmission wheel one, and the rope-winding robot 12 is provided with a transmission wheel two. The transmission wheel one is connected to the transmission wheel two through a transmission belt. The drive mechanism 6 is a geared motor. When the drive mechanism 6 is started, the drive mechanism 6 drives the transmission wheel two to rotate through the transmission wheel one, so that the rope-winding robot 12 can rotate around the gripper mechanism 7 to automatically tie the mushroom bags with rope.

[0048] like Figure 4 and Figure 8As shown, the bottom of the frame 1 is equipped with an adjustable movable frame 2. Specifically, sliders 201 are fixedly connected to both sides of the movable frame 2, and slide rails 202 that cooperate with sliders 201 are fixedly connected to the frame 1. Slider 201 is fixedly connected to slide rail 202 by fasteners. The position of slider 201 on slide rail 202 is adjusted according to the required size of the mushroom bag, which changes the distance between the swivel joint below the gripper mechanism 7 and the bag rope cutting mechanism 13, thereby realizing the processing of mushroom bags of various specifications and greatly improving the versatility of the equipment.

[0049] like Figure 2 As shown, the bag traction mechanism 3 is fixedly installed on the movable frame 2. The bag traction mechanism 3 is existing technology. The guide rod and rack on the bag traction mechanism 3 are fixedly connected to the fixed plates at the front and rear ends of the movable frame 2. Below the gripper mechanism 7, there is a support column fixedly connected to the frame 1. A lower guide wheel 14 is rotatably connected to the support column. The lower guide wheel 14 is used to pull the bag into the bag traction mechanism 3. The bag rope cutting mechanism 13 is fixedly installed on the side of the support column away from the rope-tying mechanism 5.

[0050] In this embodiment, both the bag rope cutting mechanism 13 and the mushroom bag cutting mechanism 4 use cylinders to cut the bags in a straight up or down manner. The mechanisms are easier to install and fix, do not occupy the internal lateral space of the equipment, and have a more compact structure.

[0051] In use, the position of the movable frame 2 is adjusted according to the required length of the mushroom bag. The mushroom bag roll is placed on the roll 1006. The bag head passes sequentially through the unwinding guide wheel 1004 and the unwinding guide wheel 2 1005, enters between the two guide wheels 902 of the guide wheel group 9, and exits from the channel 1 of the closing plate 903. It then passes between the two guide wheels 802 and the channel 2, and is guided sequentially through the guide wheel 3 803, the guide shaft 806, and the guide wheel 4 804 into the gripper mechanism 7. After passing through the center of the gripper mechanism 7, it is guided by the bottom of the lower guide wheel 14 and sent to the mushroom bag traction mechanism 3. The bag head is clamped and fixed by the clamping cylinder on the mushroom bag traction mechanism 3. The rope is threaded through the bag rope tensioning mechanism 11 and finally held by the rope winding robot 12 at the rope head.

[0052] During operation, the drive mechanism 6 starts, driving the rope-winding robot 12 to rotate. The rope-winding robot 12 cooperates with the rope-tying mechanism 5 to tie a slip knot on the mushroom bag. The principle of tying the slip knot is based on existing technology CN216314408U and will not be elaborated further. After tying the slip knot, the rope-winding robot 12 loosens the rope end and clamps the other end of the rope. The bag rope cutting mechanism 13 starts, moves upward, cuts the rope, and then resets. Then, the mushroom bag traction mechanism 3 starts, pulling the mushroom bag to the set length and clamping the bag again. The mushroom bag cutting mechanism 4 starts, cutting the bag. This cycle continues until all mushroom bags have been processed.

[0053] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
