Description

Technical Field

[0001] The utility model relates to the technical field of brewing process equipment, in particular to a bag sewing device applied to a broken koji system. Background Art

[0002] The sealing of the packaging bag of koji can effectively isolate the pollution of koji by external air, moisture and impurities, keep the koji dry and clean, prevent it from getting damp, mildewing or deteriorating, so as to ensure the stable quality of koji. Moreover, the packaged koji can be stacked and stored conveniently, saving space.

[0003] During the movement of the packaging bags of products such as koji towards the bag sewing machine, the height and position of the bag mouth may not reach the sewing area, resulting in the need for manual position adjustment, increasing the operation time and difficulty, as well as the demand and cost for personnel training. If the sealing position is offset, problems such as leakage of the product bag mouth and loose sealing may occur, affecting the sealing performance and compressive resistance of the packaging.

[0004] Based on this, how to ensure that the height and position of the koji bag are accurately moved to the sewing area and sealed standardly is an urgent problem for us to solve. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bag sewing device applied to a broken koji system, which overcomes the problem that the bag mouth cannot accurately reach the sewing area of the bag sewing machine in the prior art by setting a first lifting member and a clamping mechanism, so as to perform standard bag sealing.

[0006] The purpose of the utility model is mainly achieved through the following technical solutions: A bag sewing device applied to a broken koji system, comprising a support frame;

[0007] A conveyor, the bag sewing machine is connected to a position of the support frame close to the bottom;

[0008] A bag sewing machine, the bag sewing machine comprises a sewing machine and a first lifting member, the sewing machine is connected to the first lifting member, the first lifting member is connected to a position of the support frame close to the top, the sewing machine is located above the conveyor, and the first lifting member can drive the sewing machine to lift longitudinally;

[0009] A clamping mechanism, the clamping mechanism comprises a clamping member and a moving member, the clamping member is connected to the moving member, the moving member is fixed to a position of the support frame close to the top, the clamping member is used for clamping the bag mouth of the product, the moving member carries the clamping member to move towards the direction of the sewing machine, and the clamping end of the clamping member can contact the sewing machine.

[0010] The support frame is set as a support framework, and at the same time provides an installation position for products such as the bag sewing machine and the conveyor.

[0011] A conveyor is used to transport the bagged koji to the sealing area of the sewing machine, reducing the workload of operators and preventing dragging and wear of the packaging bags.

[0012] A sewing machine is used to seal the packaging bag.

[0013] A clamping mechanism is used to clamp the bag mouth to prevent the material from pouring.

[0014] The sewing machine includes a first lifting member. The first lifting member is fixed on the support frame, and the sewing machine is carried by the first lifting member to move longitudinally along the support frame. The distance between the sewing machine and the conveyor can be adjusted to adapt to different specifications of packaging bags. When the size and shape of the packaging bag change due to the change of product type and product specifications, this product can also be applicable.

[0015] During the transmission process after the koji is bagged, if problems such as the object to be sealed cannot be accurately transmitted to the sealing area or one side of the bag mouth collapses and deviates, sealing cannot be performed. In this solution, the clamping mechanism is provided with a moving member and a clamping member, which are used in cooperation with the conveyor. The clamping member can clamp the bag mouth, and then under the action of the moving member and the conveyor, the packaging bag containing koji is transmitted to the position of the sewing machine. This can prevent the object to be sealed from deviating from the predetermined trajectory or shaking and falling, ensuring that these objects can move along the predetermined path and the bag can be successfully sealed.

[0016] Furthermore, the sewing machine further includes a guiding member. The guiding member includes two sets of guiding wheels arranged at intervals. The two sets of guiding wheels form a guiding channel that can accommodate the bag mouth to pass through. The guiding wheels are rotatably connected to the support frame through the central shaft at the axis, and the axis of the guiding wheels is vertical;

[0017] The guiding member is connected to the first lifting member. The clamping end of the clamping member can abut against the end of the guiding channel, and the sewing area of the sewing machine is located above the guiding channel.

[0018] The guiding member is provided to control the movement direction and position of the packaging bag.

[0019] In this solution, a sewing machine is used to seal the koji gunny bag. During the process of sealing the gunny bag mouth by the sewing machine, the gunny bag may be tilted or toppled, resulting in inaccurate stitching. In this solution, a guiding member is provided for the sewing machine. By using the rotation of the guiding wheels, it assists the movement of the packaging bag and restricts the deviation of the packaging bag. After the packaging bag is released by the clamping member, the guiding member continues to stably support the packaging bag, enabling the packaging bag to be accurately transmitted to the sewing machine along the direction set by the guiding member for sewing treatment. This can prevent the incorrect posture of the bag on the conveyor, resulting in the inability to be normally transmitted to the sewing machine. At the same time, it can control the shape and position of the bag mouth, making the sewing of the sewing machine straight and dense, ensuring the tightness and aesthetics of the seal.

[0020] Further, the guiding member further includes two groups of pre-tightening wheels for clamping the mouth of the product, and both groups of pre-tightening wheels are rotatably connected to the support frame;

[0021] The edge of the pre-tightening wheel close to the guiding channel protrudes from the guiding channel;

[0022] A clamping area is formed between the two groups of pre-tightening wheels, and the clamping area is closely attached to the directly below of the sewing area of the sewing machine.

[0023] By setting two groups of pre-tightening wheels, and the axis of the guiding channel is the perpendicular bisector of the connecting line of the geometric centers of the two pre-tightening wheels, the two groups of pre-tightening wheels rotate in opposite directions, which can press the mouth of the bag tightly and facilitate the sewing of the sewing machine.

[0024] Further, a guiding wheel outer cover is arranged above the guiding wheel, and the edge of the guiding wheel close to the guiding channel protrudes from the guiding wheel outer cover;

[0025] An auxiliary rod is arranged above the guiding wheel outer cover, and the extending directions of one group of guiding wheels, the guiding wheel outer cover and the auxiliary rod are parallel to each other.

[0026] Setting the guiding wheel outer cover above the guiding wheel can prevent dust and water to a certain extent, increase the service life of the guiding wheel, prevent the guiding wheel from rotating or falling off and hurting people to increase safety.

[0027] An opening is left on the opposite side of the guiding wheel outer cover, so that the positions of the guiding wheel and the pre-tightening wheel can be set flexibly and adjusted under specific circumstances. The edge of the pre-tightening wheel close to the guiding channel protrudes from the guiding wheel and protrudes from the guiding wheel outer cover, and the normal use of the pre-tightening wheel and the guiding wheel is not affected by the setting of the guiding wheel outer cover.

[0028] An auxiliary rod is arranged above the guiding wheel outer cover to further support and restrain the gunny bag to be sealed, so that the mouth of the gunny bag forms a relatively flat shape under the action of the auxiliary rod and the guiding channel. Prevent the mouth of the bag from collapsing and tipping, and facilitate the sealing treatment of the mouth of the bag.

[0029] Further, the end of the guiding wheel outer cover close to the clamping member is a port, and the distance between the ports of the two guiding wheel outer covers gradually increases along the direction close to the clamping member.

[0030] The inlet of the guiding wheel outer cover is set in a funnel shape to increase the closing range and gradually close the opening. If the opening is small, the bag to be sealed cannot enter the guiding channel or cannot enter the guiding channel completely. And the structure of this solution can enable the bag to be sealed to enter the guiding channel smoothly.

[0031] Further, each set of the guide wheels includes a driving guide wheel and a driven guide wheel, and the driving guide wheel and the driven guide wheel rotate synchronously;

[0032] The guiding member further includes a speed regulating motor, and an output end of the speed regulating motor is fixedly connected to a center of the driving guide wheel.

[0033] Specifically, a set of the guide wheels at least includes a driving guide wheel and a driven guide wheel. After the driving guide wheel is driven by a power source such as a motor, the driven guide wheel is driven to rotate synchronously through a transmission member, and together they restrain and support the object to be sealed.

[0034] Connect the guide wheel to the output end of the speed regulating motor to provide power for the guide wheel. Since the speed of the motor can be adjusted, the speed of the guide wheel can be adjusted, the transmission rate of the object to be sealed in contact with the guide wheel can be controlled, and it can also adapt to different transmission speeds of the conveyor line assembly.

[0035] Further, the first lifting member includes a column and a clamping plate, the clamping plate is sleeved on the column, and the sewing machine is fixed on the clamping plate;

[0036] The column is provided with a first lifting chain longitudinally distributed, a first sprocket corresponding to the position of the first lifting chain is arranged on the clamping plate, the first sprocket is rotatably connected to the clamping plate, and the links of the first lifting chain are meshed with the teeth of the first sprocket.

[0037] Utilize the transmission of the sprocket and chain, and rotate the sprocket by means of manual or motor drive, etc., so that the sprocket carries the sewing machine to make a lifting movement along the direction of the chain layout. Thus, the height of the sewing machine is adjusted to adapt to the bag mouths of various heights.

[0038] Further, the conveyor includes a second lifting member and a conveyor line assembly, the conveyor line assembly is connected to the second lifting member, the second lifting member is arranged at a position close to the lower part of the support frame, and the second lifting member carries the conveyor line assembly to lift longitudinally.

[0039] The conveyor includes a second lifting member and a conveyor line assembly. Fix the second lifting member on the support frame, arrange the conveyor line assembly on the second lifting member, and the second lifting member can carry the conveyor line assembly to lift longitudinally along the support frame. The ground clearance height of the conveyor line assembly can be adjusted, to a certain extent, it can prevent water and insects, and is convenient for adjustment. At the same time, this device can be adjusted from low to high, can adapt to front-end and rear-end products of various heights, and enables the koji bags to enter and exit the conveyor line more smoothly.

[0040] Furthermore, the second lifting member includes two lifting frames longitudinally spaced apart. The ends of the two lifting frames are both fixed to the support frame. A fixed frame of the conveyor line assembly is longitudinally slidably connected to the lifting frame;

[0041] A second lifting chain is fixedly connected to the lifting frame. A second sprocket is rotatably connected to the fixed frame of the conveyor line assembly. The links of the second lifting chain mesh with the teeth of the second sprocket. The rotation of the second sprocket drives the fixed frame of the conveyor line assembly to lift longitudinally.

[0042] The second lifting member specifically adopts a second sprocket and chain drive to longitudinally lift the conveyor line assembly.

[0043] The lifting frame is fixedly connected to the support frame. The fixed frame of the conveyor line assembly is slidably connected to the lifting frame. A chain is arranged on the lifting frame. A second sprocket is arranged on the fixed frame of the conveyor line assembly. Through the meshing relationship between the links of the second lifting chain and the teeth of the second sprocket, a driving source is used to rotate the second sprocket, driving the fixed frame of the conveyor line assembly to lift along the rotation direction of the lifting rack.

[0044] Furthermore, the conveyor line assembly includes a first conveyor line and a second conveyor line. The first conveyor line is directly below the seam area. The second conveyor line is directly below the guiding member. The first conveyor line and the second conveyor line are separated. There is an operating gap between the first conveyor line and the second conveyor line. The size of the operating gap is smaller than the size of the product. The adjacent ends of the first conveyor line and the second conveyor line are aligned. Belt adjusting plates are installed on both the first conveyor line and the second conveyor line.

[0045] Since the seam area needs to be sewn, the conveying speed may be different from other positions. Therefore, in this solution, conveyor lines are respectively arranged below the seam area and the guiding area, and belt adjusting plates are arranged at the feeding ports of the two conveyor lines. Then both conveyor lines can independently adjust the conveying direction and conveying speed of the conveyor belt. It can make the conveying speeds and directions of the two conveyor lines match, and can also adapt to various different materials, models, sizes of the bags to be sealed and different sewing methods.

The illustrative embodiments and descriptions thereof of the present invention are only used to explain the present invention and do not limit the present invention.

[0056] Embodiment:

[0057] As Figures 1 - 4 shown, a sewing device for a broken koji system in the technical field of brewing process equipment is disclosed, including a support frame 1;

[0058] a conveyor 3, and the sewing machine for packaging 2 is connected to a position near the bottom of the support frame 1;

[0059] Sewing machine 2, the sewing machine 2 includes a sewing machine 21 and a first lifting member 22, the sewing machine 21 is connected to the first lifting member 22, the first lifting member 22 is connected to a position near the top of the support frame 1, the sewing machine 21 is located above the conveyor 3, and the first lifting member 22 can drive the sewing machine 21 to lift longitudinally;

[0060] Clamping mechanism 4, the clamping mechanism 4 includes a clamping member 41 and a moving member 42, the clamping member 41 is connected to the moving member 42, the moving member 42 is fixed to a position near the top of the support frame 1, the clamping member 41 is used to clamp the bag mouth of the product, the moving member 42 carries the clamping member 41 and moves towards the sewing machine 21, and the clamping end of the clamping member 41 can contact the sewing machine 21.

[0061] A support frame 1 is provided as a support frame and at the same time provides an installation position for products such as the sewing machine 2 and the conveyor 3.

[0062] As an implementation manner of the above solution, the support frame 1 includes two layers, which are welded by channel steel and square tubes.

[0063] Conveyor 3, which is used to transport the bagged koji to the sealing area of the sewing machine 2, reduces the workload of the operator and prevents dragging and wearing of the packaging bag.

[0064] Sewing machine 2, which is used to seal the packaging bag.

[0065] When the above solution is specifically implemented, the sewing machine 2 can use the sewing machine 21 for sewing, or can use a heat sealer to thermally press the bag mouth.

[0066] Clamping mechanism 4, which is used to clamp the bag mouth to prevent the material from pouring.

[0067] The sewing machine 2 includes a first lifting member 22. The first lifting member 22 is fixed on the support frame 1, and the sewing machine 21 is carried by the first lifting member 22 to lift longitudinally along the support frame 1. The distance between the sewing machine 2 and the conveyor can be adjusted to adapt to different specifications of packaging bags. When the size and shape of the packaging bag are changed due to changes in product types and product specifications, this product can also be applicable.

[0068] During the transmission process after the koji is bagged, if there are problems such as the object to be sealed not being accurately transmitted to the sealing area or one side of the bag mouth collapsing and deviating, sealing cannot be performed. In this solution, the clamping mechanism 4 is provided with a moving member 42 and a clamping member 41, which are used in cooperation with the conveyor 3. The clamping member 41 can clamp the bag mouth, and then under the action of the moving member 42 and the conveyor 3, the moving member 42 drives the clamping member 41 to move along the conveying direction of the conveyor 3, moving the packaging bag filled with koji to the position of the sewing machine 2. This prevents the object to be sealed from deviating from the predetermined trajectory or shaking, tipping, etc., ensuring that these objects can move along the predetermined path and enabling smooth bag sealing.

[0069] The clamping member 41 is any device in the prior art that can clamp the bag mouth.

[0070] Furthermore, the sewing machine 2 further includes a guiding member 23. The guiding member 23 includes two sets of guiding wheels arranged at intervals. The two sets of guiding wheels form a guiding channel that can accommodate the bag mouth to pass through. The guiding wheels are rotatably connected to the support frame 1 through the central shafts at their axles, and the axes of the guiding wheels are vertical;

[0071] The guiding member 23 is connected to the first lifting member 22. The clamping end of the clamping member 41 can abut against the end of the guiding channel, and the sewing area of the sewing machine 21 is located above the guiding channel.

[0072] The guiding member 23 is provided to control the orientation and position of the packaging bag.

[0073] In this solution, the sewing machine 21 is used to seal the koji gunny bag. During the process of the sewing machine 21 sealing the bag mouth of the gunny bag, the gunny bag may tilt or tip over, resulting in inaccurate sewing. In this solution, the guiding member 23 is provided for the sewing machine 2. By the rotation of the guiding wheels, it assists the movement of the packaging bag and restricts the deviation of the packaging bag. After the packaging bag is released by the clamping member 41, the guiding member 23 continues to stably support the packaging bag, enabling the packaging bag to be accurately transmitted to the sewing machine 2 along the direction set by the guiding member 23 for sewing treatment. This can prevent the incorrect pose of the bag on the conveyor 3, resulting in the inability to be normally transmitted to the sewing machine 2. At the same time, it can control the shape and position of the bag mouth, making the sewing of the sewing machine 21 straight and dense, ensuring the tightness and aesthetics of the seal.

[0074] Furthermore, the guiding member 23 further includes two sets of pre-tightening wheels 233. The pre-tightening wheels 233 are used to clamp the bag mouth of the product. Both sets of pre-tightening wheels 233 are rotatably connected to the support frame 1;

[0075] The edges of the pre-tightening wheels 233 close to the guiding channel protrude from the guiding channel;

[0076] A clamping area is formed between the two groups of pre-tightening wheels 233, and the clamping area is closely attached to the exact lower part of the seam area of the sewing machine 21.

[0077] Two groups of pre-tightening wheels 233 are provided. The axis of the guiding channel is the perpendicular bisector of the connection line of the geometric centers of the two pre-tightening wheels 233. Then, the two groups of pre-tightening wheels 233 rotate in opposite directions, which can press the bag mouth tightly and facilitate the sewing of the sewing machine 21.

[0078] Furthermore, a guiding wheel outer cover 235 is provided above the guiding wheel, and the guiding wheel protrudes from the guiding wheel outer cover 235.

[0079] An auxiliary rod 236 is provided above the guiding wheel outer cover 235. The extending direction of the guiding wheel outer cover 235, the extending direction of the auxiliary rod 236, and the extending direction of each group of guiding wheels are all parallel to each other.

[0080] Setting the guiding wheel outer cover 235 above the guiding wheel can prevent dust and water to a certain extent, increase the service life of the guiding wheel, and prevent the guiding wheel from rotating or falling off and hurting people to increase safety.

[0081] An opening is left on one side opposite to the guiding wheel outer cover 235, so that the positions of the guiding wheel and the pre-tightening wheels 233 can be flexibly set and adjusted under specific circumstances. The edge of the pre-tightening wheel 233 close to the guiding channel protrudes from the edge of the guiding wheel close to the guiding channel and protrudes from the guiding wheel outer cover 235, and the normal use of the pre-tightening wheel 233 and the guiding wheel is not affected by the setting of the guiding wheel outer cover 235.

[0082] Setting the auxiliary rod 236 above the guiding wheel outer cover 235 further supports and restrains the gunny bag to be sealed, so that the bag mouth forms a relatively flat shape under the action of the auxiliary rod 236 and the guiding channel. Prevent the bag mouth from collapsing and tipping, and facilitate the sealing treatment of the bag mouth.

[0083] Furthermore, the end of the guiding wheel outer cover 235 close to the clamping member 41 is a port, and the distance between the ports of the two guiding wheel outer covers 235 gradually increases along the direction close to the clamping member 41.

[0084] The inlet of the guiding wheel outer cover 235 is set in a funnel shape to increase the closing range and gradually close the opening. If the opening is small, the bag to be sealed cannot enter the guiding channel or cannot enter the guiding channel completely. And the structure of this solution can enable the bag to be sealed to enter the guiding channel smoothly.

[0085] Furthermore, each group of guiding wheels includes a driving guiding wheel 231 and a driven guiding wheel 232, and the driving guiding wheel 231 and the driven guiding wheel 232 rotate synchronously.

[0086] The guide member 23 further includes a speed control motor 234, and the output end of the speed control motor 234 is fixedly connected to the center of the driving guide wheel 231.

[0087] Specifically, a set of the guide wheels at least includes a driving guide wheel 231 and a driven guide wheel 232. After the driving guide wheel 231 is driven by a power source such as a motor, it drives the driven guide wheel 232 to rotate synchronously through a transmission member, and jointly restricts and supports the object to be sealed.

[0088] As an implementable manner of the above solution, a belt drive or a chain drive is adopted between the driving guide wheel 231 and the driven guide wheel 232, and they are driven by one driving source.

[0089] As an implementable manner of the above solution, the driving guide wheel 231 and the driven guide wheel 232 are driven by two independent power sources.

[0090] Connect the guide wheel to the output end of the speed control motor 234 to provide power for the guide wheel. Since the speed of the motor is adjustable, the speed of the guide wheel is adjustable, the transmission rate of the object to be sealed contacted by the guide wheel can be controlled, and it can also adapt to different transmission speeds of the conveyor line assembly 32.

[0091] As an implementable manner of the above solution, the speed control motor 234 is an explosion-proof AC speed control motor.

[0092] Furthermore, the first lifting member 22 includes a column 221 and a clamping plate 224. The clamping plate 224 is sleeved on the column 221, and the sewing machine 21 is fixed on the clamping plate 224;

[0093] The column 221 is provided with a first lifting chain 222 distributed longitudinally. A first sprocket 223 is provided at a position corresponding to the first lifting chain 222 on the clamping plate 224. The first sprocket 223 is rotatably connected to the clamping plate 224, and the links of the first lifting chain 222 are meshed with the teeth of the first sprocket 223.

[0094] Utilize the transmission of the sprocket and chain, and rotate the sprocket by means of manual or motor drive, etc., so that the sprocket drives the sewing machine 21 to make a lifting movement along the direction of the chain layout. Thus, the height of the sewing machine 21 is adjusted to adapt to the bag openings of various heights.

[0095] As an implementable manner of the above solution, the top of the first lifting chain 222 is flush with the top end of the column 221 and is fixed to the column 221 by a chain fixing pin;

[0096] As an implementable manner of the above solution, a BAFH-M adjustable position set screw handle can be used to adjust the tension of the chain, reduce the vibration and noise of the chain, and improve the smoothness and efficiency of the transmission.

[0097] As an implementable mode of the above solution, a BAFH-M adjustable position set handle can be used to install or adjust the position and angle of the chain guide rail, ensuring that the chain maintains the correct path and position during transmission, and preventing faults such as chain derailment or chain jamming.

[0098] As an implementable mode of the above solution, a BAFH-M adjustable position set handle can be used to help installers quickly and accurately install and position transmission components. When replacing parts such as chains or sprockets, it provides necessary support and fixation functions, ensuring the safety and convenience of the operation process.

[0099] As an implementable mode of the above solution, an LKZP-M double locking handle can be used to fix the position of the worm or worm gear, preventing movement or loosening during transmission.

[0100] As an implementable mode of the above solution, the sprocket is fixedly connected to the drive shaft. Both ends of the drive shaft are rotatably connected to the clamping plate 224 and protrude from the clamping plate 224. A driving member is installed at the end of the drive shaft away from the sewing machine 21, so that the sprocket drives the sewing machine 21 to lift. Specifically, a turbine can be installed at one end of the drive shaft, and the turbine can be rotated by a worm, driving the sprocket on the drive shaft to rotate; or a motor can be directly connected, and the output end of the motor is connected to the drive shaft, thereby realizing the lifting of the sewing machine 21.

[0101] Furthermore, the conveyor 3 includes a second lifting member 31 and a conveyor line assembly 32. The conveyor line assembly 32 is connected to the second lifting member 31. The second lifting member 31 is disposed at a position close to the lower part of the support frame 1, and the second lifting member 31 carries the conveyor line assembly 32 to lift longitudinally.

[0102] The conveyor 3 includes a second lifting member 31 and a conveyor line assembly 32. The second lifting member 31 is fixed on the support frame 1, and the conveyor line assembly 32 is disposed on the second lifting member 31. The second lifting member 31 can carry the conveyor line assembly 32 to lift longitudinally along the support frame 1. The ground clearance of the conveyor line assembly 32 can be adjusted, to a certain extent, preventing water and insects, and facilitating adjustment. At the same time, this device can be adjusted from low to high, and can adapt to front-end and rear-end products of various heights, enabling the koji bags to enter and exit the conveyor line relatively smoothly.

[0103] Furthermore, the second lifting member 31 includes two lifting frames 311 spaced longitudinally. The ends of the two lifting frames 311 are both fixed on the support frame 1, and a conveyor line assembly fixing frame 317 is longitudinally slidably connected to the lifting frame 311;

[0104] A second lifting chain 312 is fixedly connected to the lifting frame 311. A second sprocket 314 is rotatably connected to the conveyor line assembly fixing frame 317. The links of the second lifting chain 312 are meshed with the teeth of the second sprocket 314. The rotation of the second sprocket 314 drives the longitudinal lifting of the conveyor line assembly fixing frame 317.

[0105] The second lifting member 31 specifically adopts a second sprocket 314 and chain drive to longitudinally lift the conveyor line assembly 32.

[0106] The lifting frame 311 is fixedly connected to the support frame 1. The conveyor line assembly fixing frame 317 is slidably connected to the lifting frame 311. A chain is arranged on the lifting frame 311. A second sprocket 314 is arranged on the conveyor line assembly fixing frame 317. Through the meshing relationship between the links of the second lifting chain 312 and the teeth of the second sprocket 314, the rotation of the second sprocket 314 is driven by a driving source to drive the conveyor line assembly fixing frame 317 to lift along the rotation direction of the lifting rack.

[0107] As a specific implementation manner of the above solution, two lifting frames 311 are longitudinally spaced apart. The two ends of the lifting frame 311 are respectively fixed to the top and bottom of the support frame 1. A longitudinally distributed chain is arranged on the side of the lifting frame 311 away from the support frame 1. The conveyor line assembly fixing frame 317 that horizontally protrudes from the support frame 1 is slidably connected to the left and right sides of the lifting frame 311 where the chain is arranged. A sprocket is arranged on the conveyor line assembly fixing frame 317 at a position corresponding to the chain. The sprocket is rotatably connected to both sides of the conveyor line assembly fixing frame 317 through a transmission shaft 313. The transmission shafts 313 on the two lifting frames 311 are connected by a connecting rod 315. An explosion-proof drive motor 316 and a speed reducer are also connected to the connecting rod 315. The rotation of the connecting rod 315 is controlled by a motor, thereby driving the sprocket on the connecting rod 315 to rotate.

[0108] As an alternative solution to the above solution, the sprocket and chain can be replaced with a gear and rack, or implemented with products such as a cylinder drag chain.

[0109] Furthermore, the conveyor line assembly 32 includes a first conveyor line 321 and a second conveyor line 322. The first conveyor line 321 is directly below the seam area. The second conveyor line 322 is directly below the guiding member 23. The first conveyor line 321 and the second conveyor line 322 are separated. There is an operating gap between the first conveyor line 321 and the second conveyor line 322. The size of the operating gap is smaller than the size of the product. The adjacent ends of the first conveyor line 321 and the second conveyor line 322 are aligned. Belt adjusting plates are installed on both the first conveyor line 321 and the second conveyor line 322.

[0110] Since the sewing area needs to sew the bags, the conveying speed may be different from other positions. Therefore, in this solution, conveyor lines are respectively arranged below the sewing area and the guiding area, and belt adjusting plates are arranged at the feeding ports of the two conveyor lines. Then, the conveying directions and speeds of the conveyor belts of the two conveyor lines can be adjusted independently. It can make the conveying speeds and directions of the two conveyor lines match, and can also adapt to various types of bags to be sealed with different materials, models, sizes and different sewing methods.

[0111] As an implementable solution of the above solution, small idlers are arranged between the first conveyor line 321 and the second conveyor line 322, so that the items on one conveyor line can move naturally to the other conveyor line.

[0112] As an implementable solution of the above solution, the distance between the first conveyor line 321 and the second conveyor line 322 is small, and the items on one conveyor line can move naturally to the other conveyor line.

[0113] The specific embodiments described above have further elaborated on the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention.
