[0069] The tensioning assembly includes:

[0070] A first slider 202 and a second slider 203, both of which are slidably connected to the guide rail 201;

[0071] Two connecting seats 301, the two connecting seats 301 are respectively fixed on the top of the first slider 202 and the second slider 203, the side walls of the two connecting seats 301 are provided with circular holes, and the two circular holes are rotatably provided with annular seats 302;

[0073] Two transmission assemblies, the two transmission assemblies are respectively fixed to the two annular seats 302;

[0074] A power assembly is arranged on the top of the first slider 202 , and is connected to one of the transmission assemblies. The power assembly is used to drive the two annular seats 302 to rotate.

[0075] The second sliders 203 in the two tensioning assemblies slide on the guide rails 201 , and when they are separated from each other, the expansion and tensioning of the container bag are achieved through the shaft 303 on the second sliders 203 .

[0076] Furthermore, it also includes:

[0077] Two support plates 801, both of which are arranged on the top of the base 1;

[0078] A bidirectional screw rod 803, which is rotatably arranged on two support plates 801;

[0079] A second motor 802, the second motor 802 and one of the support plates 801 are fixed, and the output shaft of the second motor 802 and the bidirectional screw rod 803 are fixed;

[0080] Two transmission seats 804 are respectively fixed to the two second sliders 203 , and a shaft sleeve 805 is provided through the side wall of each transmission seat 804 . The bidirectional screw rod 803 passes through the two shaft sleeves 805 , and the bidirectional screw rod 803 and the two shaft sleeves 805 are threadedly connected.

[0081] When the second motor 802 is working, it drives the bidirectional screw rod 803 to rotate, and cooperates with the transmission of the shaft sleeve 805 and the transmission seat 804 to enable the two second sliders 203 to move closer to or separate from each other.

[0082] Furthermore, the tensioning assembly also includes:

[0083] Two ear plates 204, the two ear plates 204 are respectively fixed to the first slider 202 and the second slider 203;

[0084] An electric push rod 205, the electric push rod 205 is fixed on one of the ear plates 204, and the output end of the electric push rod 205 is fixed to the other ear plate 204;

[0085] Two plates 309 (such as Figure 7 As shown), two plates 309 are rotatably disposed at the ends of the two shafts 303 respectively;

[0086] A telescopic rod 310, the telescopic rod 310 is fixed on one of the plates 309, and the telescopic end of the telescopic rod 310 is fixed to the other plate 309;

[0087] The support 304 is rotatably designed at the end of the shaft 303 close to the first slider 202, and a ball 305 is rotatably arranged at the bottom of the support 304, and the ball 305 is in conflict with the top of the base 1;

[0088] The rubber sleeve 306 is rotatably connected to the support 304 , and the rubber sleeve 306 is fixed to the shaft 303 .

[0089] When the electric push rod 205 is working, the two ear plates 204 are separated from or approached to each other. Since the second slider 203 is kept fixed under the restriction of the shaft sleeve 805, the transmission seat 804 and the bidirectional screw rod 803, the distance between the first slider 202 and the second slider 203 can be adjusted by the working of the electric push rod 205.

[0090] Through the support 304 and the ball 305 at the bottom of the support 304, one of the shafts 303 and the rubber sleeve 306 on the shaft 303 can be supported, so that the position of the rubber sleeve 306 can be adjusted;

[0091] Through the two plates 309 and the telescopic rod 310 between the two plates 309 , the sliding between the shaft 303 and the annular seat 302 is coordinated so that the shaft 303 on the first slider 202 and the second slider 203 can move along the axial direction of the annular seat 302 at the same time.

[0092] Furthermore, a plurality of protrusions are disposed on the inner wall of the annular seat 302 , a plurality of grooves are opened on the side wall of the shaft body 303 , and the plurality of protrusions and the plurality of grooves are slidably connected one to one.

[0093] Furthermore, the transmission assembly includes:

[0094] An annular plate 307, the annular plate 307 is fixed on the side wall of the annular seat 302;

[0095] The rubber ring 308 is fixedly sleeved on the annular plate 307 , and a plurality of protrusions are formed on the side wall of the rubber ring 308 .

[0096] When the first slider 202 approaches the second slider 203, the two rubber rings 308 contact each other, and when one of the rubber rings 308 rotates, the other rubber ring 308 rotates in the opposite direction. The protrusions on the rubber rings 308 ensure the friction between the two rubber rings 308, so that the two rubber rings 308 can rotate in opposite directions.

[0097] The power transmission is performed by the approach and collision of the two rubber rings 308, so as to avoid the phenomenon that the two spur gears in the same plane are close to each other but cannot mesh, thereby ensuring the normal transmission of power.

[0098] Furthermore, the power assembly includes:

[0099] A first motor 401, the first motor 401 is fixed on the second slider 203, and the first motor 401 is a self-locking motor;

[0100] A pulley 402, the pulley 402 is fixed on the output shaft of the first motor 401;

[0101] A transmission ring 404, the transmission ring 404 is fixed on the side wall of the annular plate 307 close to the first motor 401;

[0102] The transmission belt 403 is sleeved on the pulley 402 and the transmission ring 404 .

[0103] Further, the adjustment component includes:

[0104] Two hydraulic push rods 501, both of which are fixed on the top of the base 1;

[0105] The electric slide 502 and the telescopic ends of the two hydraulic push rods 501 are fixed.

[0106] Further, the fixing component includes:

[0107] The first fixing seat 601 is fixed on the top of the base 1, and a magnet 606 (such as Figure 3 shown);

[0108] A connecting plate 603, the connecting plate 603 is fixed on the top of the electric slide 502, connecting holes are provided at both ends of the top of the connecting plate 603, connecting rods 604 are slidably inserted into the two connecting holes, two springs 605 are provided on the top of the connecting plate 603, and the two springs 605 are respectively fixed to the two connecting rods 604;

[0109] The second fixing base 602 is fixed at the bottom ends of the two connecting rods 604 .

[0110] Further, the shearing component comprises:

[0111] A support base 701, the support base 701 is slidably disposed on the top of the base 1, and two plug holes 705 are provided on the top of the support base 701;

[0112] The movable seat 702 is fixed to the movable end of the electric slide 502, the bottom of the movable seat 702 is higher than the bottom of the second fixed seat 602, and latches 704 are arranged on both sides of the bottom of the movable seat 702, and the two latches 704 correspond to the two sockets 705 one by one;

[0113] The shearing knife 703 is fixed on the side wall of the movable seat 702 , the bottom end of the shearing knife 703 is lower than the bottom end of the movable seat 702 , and the bottom end of the shearing knife 703 is higher than the bottom end of the second fixed seat 602 .

[0114] The magnet 606 adsorbs the support base 701, so that when the support base 701 and the movable base 702 are separated, the support base 701 is fixed, and when the movable base 702 is lowered, the latch 704 on the movable base 702 can accurately enter the insertion hole 705;

[0115] Since the bottom end of the movable seat 702 is higher than the bottom end of the second fixed seat 602, when the first fixed seat 601 and the second fixed seat 602 fix the container bag, there is still a gap between the movable seat 702 and the support seat 701 to ensure that the container bag can pass through the support seat 701 and the movable seat 702;

[0116] When performing shearing work, the movable seat 702 needs to be further lowered. At this time, the connecting plate 603 also drops accordingly. Since the connecting plate 603 is connected to the second fixed seat 602 through the connecting rod 604, sliding occurs between the connecting rod 604 and the connecting plate 603 during the further lowering of the movable seat 702, thereby avoiding the inability of the movable seat 702 to drop due to the inability to change the position of the second fixed seat 602.

[0117] The specific working method is as follows: when in use, firstly, the two ear plates 204 are moved away from each other through the electric push rod 205, that is, the first slider 202 and the second slider 203 are moved away from each other. Since the second slider 203 is kept fixed under the action of the transmission seat 804, the shaft sleeve 805 and the bidirectional screw rod 803, at this time, the first slider 202 is away from the second slider 203, so that the shaft body 303 on the first slider 202 and the shaft body 303 on the second slider 203 are separated, and then the container bag is passed through the first fixed seat 601 and the second fixed seat 602, and the bag mouth of the container bag is opened, so that the container bag passes through the outer walls of the two shaft bodies 303 close to the electric slide 502, that is, the two shaft bodies 303 in the middle are inside the container bag (such as Fig.10 As shown), the two outer shaft bodies 303 are outside the container bag;

[0118] Then, the switch of the second motor 802 is turned on. When the second motor 802 is working, it drives the bidirectional screw rod 803 to rotate, and cooperates with the transmission seat 804 and the shaft sleeve 805 to separate the two second sliders 203 from each other, and then the container bag is opened through the shaft bodies 303 on the two second sliders 203;

[0119] The switch of the electric push rod 205 is turned on again, so that the first slider 202 and the second slider 203 are close to each other. During the process of the first slider 202 and the second slider 203 being close to each other, the shaft 303 on the first slider 202 is close to the shaft 303 on the second slider 203, so that the container bag is fixed by the rubber sleeve 306 and the shaft 303 on the second slider 203. When the first slider 202 and the second slider 203 are close to each other, the two rubber rings 308 contact each other. At this time, the switch of the first motor 401 is turned on, and the first motor 401 is turned on. When 01 is working, the corresponding annular plate 307 is driven to rotate by the pulley 402, the transmission belt 403 and the transmission ring 404. The friction between the two rubber rings 308 makes the two annular plates 307 rotate in opposite directions. Then, the two shaft bodies 303 are driven in opposite directions by the transmission of the annular seat 302. The rubber sleeve 306 is used to move the container bag between the two shaft bodies 303, so that the shaft bodies 303 on the two second sliders 203 can be opened and tensioned during the separation process.

[0120] In summary, during the loading process, the container bag can be randomly placed between the two shafts 303 close to the electric slide 502 without leveling the container bag. Subsequently, the container bag can be adjusted in position by rotating the rubber sleeve 306 so that the container bag between the two shafts 303 is the same length, and the two shafts 303 are moved away from each other to achieve the smooth opening of the container bag. If only the conventional two shafts 303 are used to separate and open the container bag, in order to avoid excessive friction between the container bag and the shaft 303, the container bag needs to be adjusted after loading so that the container bag between the two shafts 303 is the same length, and the container bag is opened with the separation of the two shafts 303. Therefore, the conventional method is less efficient. If the container bag below the shaft 303 is blocked or stacked severely, the conventional method will also cause the container bag above the two shafts 303 to be over-stretched, which can easily cause damage to the container bag.

[0121] When the container bag is fully opened, the electric push rod 205 controls the first slider 202 and the second slider 203 to separate, so that the rubber sleeve 306 no longer squeezes the container bag;

[0122] The switches of the two hydraulic push rods 501 are turned on, so that the electric slide 502 descends. When the electric slide 502 descends, the second fixed seat 602 is driven to descend through the connecting plate 603, the spring 605 and the connecting rod 604, so that the second fixed seat 602 is close to the first fixed seat 601, and then the end of the container bag is fixed by squeezing the second fixed seat 602 and the first fixed seat 601. Since the bottom end of the moving seat 702 is higher than the bottom end of the second fixed seat 602, there is a gap between the moving seat 702 and the supporting seat 701 at this time, and the latch 704 enters the socket 705 at the same time;

[0123] When the switch of the electric slide 502 is turned on and the electric slide 502 is working, the movable seat 702 is driven to move. Through the cooperation of the latch 704 and the socket 705, the support seat 701 is also moved. When the support seat 701 moves, it first contacts the support 304, and then the support seat 701 pushes the support 304 to move. During the movement of the support 304, the corresponding shaft body 303 slides along the annular seat 302. Through the action of the two plates 309 and the telescopic rod 310, the other shaft body 303 is also moved. At this time, the container bag is clamped by the first fixed seat 601 and the second fixed seat 602, so that the shaft bodies 303 on the two second sliders 203 are gradually pulled out of the container bag. After the shaft body 303 is pulled out of the container bag, the container bag immediately enters between the support seat 701 and the movable seat 702, so that after the shaft body 303 is pulled out of the container bag, it can also ensure that the container bag is in a flat state.

[0124] When the support seat 701 and the movable seat 702 move to the bag opening of the container bag, the electric slide 502 continues to descend through the operation of the hydraulic push rod 501, so that the support seat 701 and the movable seat 702 completely squeeze the container bag, and the squeezing position is at the bag opening of the container bag. At this stage, when the movable seat 702 descends, the shearing knife 703 on the movable seat 702 and the support seat 701 provide support for the container bag, thereby realizing the shearing work of the bag opening of the container bag.

[0125] It is worth noting that the power parts in the present invention (such as the electric push rod 205, the hydraulic push rod 501, the electric slide 502, the first motor 401, the second motor 802, etc.) can all be controlled by a single-chip microcomputer to achieve automated production. Since this type of automated control is relatively simple and belongs to a mature existing technology, the present invention will not go into details.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
