[0041] Embodiment 1:

[0042] The invention provides a material bag cooling device.

[0043] In one embodiment of the present invention, a material bag cooling device includes a support frame 1, a packaging machine 2, a bag stacking machine 3 and a cooling device 4, wherein the packaging machine 2 is arranged on one side of the support frame 1, and the packaging machine 2 is used to package the seasoning and make a material bag belt 100 filled with the seasoning, and the cooling device 4 is formed with a feeding port 5 and a discharging port 6 for the material bag belt 100 to extend in and out, and the cooling device 4 is arranged on the support frame 1 and is used to cool the material bag belt 100, and the bag stacking machine 3 is correspondingly arranged to stack the material bag belt 100 extending from the cooling device 4 through the bag stacking machine 3; a guiding assembly is arranged on the support frame 1, and the guiding assembly is located between the packaging machine 2 and the bag stacking machine 3, so as to pull the material bag belt 100 extending from the packaging machine 2 to the bag stacking machine 3 through the guiding assembly, and an adjusting mechanism for adjusting the tension of the material bag belt 100 is arranged on the bag stacking machine 3.

[0044] Specifically, Figures 1 to 12 As shown, in a bag cooling device of the present invention, the packaging machine 2 can be an intelligent V-type servo packaging machine 2 proposed by the applicant in the patent publication number CN212333044U, which has the characteristics of high automation, intelligent coding, greatly reducing manual pressure, clear and simple structural design, easy maintenance, etc. The packaging machine 2 can package the seasoning and make a continuous bag belt 100, so as to facilitate the subsequent transportation and subpackaging of the bag.

[0045] Furthermore, when it is necessary to cool the material bag 100 (such as an oil bag), since the support frame 1 is provided with a cooling device 4, and the cooling device 4 is formed with a feed port 5 and a discharge port 6 for the material bag 100 to extend in and out, the staff can extend the material bag 100 from the feed port 5 into the cooling device 4. The cooling device 4 is provided with a corresponding cooling system, such as air cooling, water cooling, etc., so that the cooling device 4 can quickly cool down the high-temperature material bag 100, effectively preventing the quality of the seasoning from being degraded after packaging or causing packaging damage due to excessively high temperature, thereby not only helping to maintain the taste of the seasoning, but also extending the shelf life of the seasoning bag. In addition, when the material bag belt 100 extends from the discharge port 6 of the cooling device 4 after the temperature reduction treatment, since the bag stacking machine 3 is correspondingly arranged to the discharge port 6, the material bag belt 100 automatically extends into the bag stacking machine 3, so that the bag stacking machine 3 can stack the cooled material bag belt 100 for subsequent transportation and conveying of the material bag belt 100.

[0046] At the same time, when the material bag belt 100 (such as the vegetable bag after drying) does not need to be cooled, since the support frame 1 is provided with a guide component, and the guide component is located between the packaging machine 2 and the bag stacking machine 3, the guide component can be a plurality of rollers, so that the material bag belt 100 extending from the packaging machine 2 can be directly and smoothly guided and transported to the bag stacking machine 3 through the guide component. At this time, the material bag belt 100 can be stacked by the bag stacking machine 3 for subsequent transportation and transportation of the material bag belt 100. It can be seen that the present invention can realize the continuous processing of packaging, cooling and stacking of seasonings, and the overall processing process is efficient and smooth. There is no need for staff to transfer or collect the material bag belt 100 in the middle, which simplifies the operation steps, improves the processing efficiency, and facilitates the batch production and processing of seasoning bags. In addition, it is obvious that since the present invention is provided with a cooling device 4 and a guiding assembly, the staff can choose whether to cool the material bag tape 100 according to the different types of the material bag tape 100, and whether the material bag tape 100 needs to be cooled or not, the bag stacking machine 3 can automatically stack them, thereby not only improving the adaptability of the present invention to the processing requirements of different material bag tapes 100, but also being flexible and convenient to use, and also facilitating subsequent transportation, subpackaging, etc.

[0047] It can be understood that when the material bag belt 100 enters the bag stacking machine 3 from the cooling device 4 or is directly transported from the packaging machine 2 to the bag stacking machine 3, since the conveying speeds of the cooling device 4, the packaging machine 2 and the bag stacking machine 3 for the material bag belt 100 are not consistent, if the conveying speed of the cooling device 4 or the packaging machine 2 is too fast and the conveying speed of the bag stacking machine 3 is too slow, it is easy to cause the material bag belt 100 to become loose, accumulate or clogged in the bag stacking machine 3. However, since the bag stacking machine 3 in the present invention is provided with an adjusting mechanism, the adjusting mechanism can be a tensioning wheel 31 or a roller that can be limitedly moved relative to the cooling device 4. The tensioning degree of the material bag belt 100 can be adjusted through the adjusting mechanism, so that the material bag belt 100 is always in a straight state during the entire conveying process, ensuring the stability of the material bag belt 100 during the conveying process, and thus effectively preventing the material bag belt 100 from loosening, piling up or clogging in the bag stacking machine 3 due to inconsistent conveying speeds of the cooling device 4 or the packaging machine 2. This not only reduces the frequency of equipment shutdown maintenance and improves production and processing efficiency, but also ensures the smoothness of the overall processing flow and is reliable to use.

[0048] It is worth noting that since the packaging machine 2 is arranged on one side of the support frame 1, the cooling device 4 is arranged on the support frame 1, and the bag stacking machine 3 is located below the support frame 1 and is arranged corresponding to the discharge port 6 of the cooling device 4, the staff can stand below the support frame 1 to operate the packaging machine 2, the cooling device 4 and the bag stacking machine 3. The overall structural design layout is simple and reasonable, which is not only easy to maintain, but also realizes the high integration and automation of different processing steps of the material bag belt 100, and also reduces the space occupied by the present invention, thereby improving the space utilization rate of the present invention.

[0049] It should be noted that the packaging machine 2 and the cooling device 4 in the present invention are both provided with a control module, and the control module and its communication method with the packaging machine 2 and the cooling device 4 are mature prior arts, which are not described here, and the structural composition is not shown in the drawings of the specification. The present invention is only aimed at solving the problem that the seasoning package of instant noodles cannot be cooled quickly during the production process, which makes it difficult to ensure the flavor and quality of the seasoning, and cannot realize the continuous processing of packaging, cooling and stacking of the seasoning, resulting in low production efficiency.

[0050] In one embodiment, the cooling device 4 includes a box body 7, a first driving member 8, a conveying mechanism 9 and a cooling mechanism 10 for outputting cold air into the box body 7. The first driving member 8 is arranged on the box body 7 and is transmission-connected to the conveying mechanism 9. The conveying mechanism 9 is arranged in the box body 7 and is used to convey the material bag belt 100. The conveying mechanism 9 includes a first conveying component 11 and a second conveying component 12. A serpentine material conveying channel 13 for accommodating the material bag belt 100 is formed between the first conveying component 11 and the second conveying component 12.

[0051] Specifically, Figure 1 , Figure 5 , Figure 8 and Fig. 9 As shown, in the cooling device 4 of the present invention, a relatively closed space can be provided by the box body 7, so that the cold air output by the cooling mechanism 10 can circulate in the box body 7, thereby effectively cooling the material bag belt 100. It is worth noting that the box body 7 is usually made of heat-insulating material to reduce the influence of external heat on the internal temperature; and the feed port 5 and the discharge port 6 are opened on the box body 7. In addition, the box body 7 is also provided with a cold air input port and an exhaust port to meet the transportation of the material bag belt 100 and the circulation requirements of the cold air. Furthermore, since the first driving member 8 is arranged on the box body 7 and is transmission-connected with the conveying mechanism 9, the first driving member 8 can be a motor in the prior art, and the transmission connection method of the first driving member 8 and the conveying mechanism 9 can be a chain drive or a gear drive, so that the conveying mechanism 9 can smoothly convey the material bag belt 100.

[0052] It can be understood that since a serpentine material conveying channel 13 is formed between the first conveying component 11 and the second conveying component 12 in the conveying mechanism 9, the serpentine material conveying channel 13 can change the conveying path of the material bag belt 100 to form multiple curved sections, thereby increasing the residence time of the material bag belt 100 in the box 7 and the contact area with the cold air. Furthermore, when the material bag belt 100 needs to be cooled, the staff can fix one end of the material bag belt 100 to the first conveying component 11 or the second conveying component 12 by a clamp (such as a splint or a clamp, etc.). At this time, the material bag belt 100 is in the serpentine feed channel 13. With the operation of the first driving member 8, the first conveying component 11 and the second conveying component 12 rotate synchronously relative to the box body 7 under the action of the first driving member 8, thereby making the material bag belt 100 move in the serpentine feed channel 13; at the same time, during the movement of the material bag belt 100 in the serpentine feed channel 13, the cooling mechanism 10 delivers cold air into the box body 7, thereby realizing rapid cooling of the material bag belt 100, and the structural design is simple and reasonable.

[0053] In one embodiment, a plurality of rotating shafts 14 are spaced and staggered in a height direction inside the box body 7, and two groups of first conveying components 11 are spaced apart on the plurality of rotating shafts 14, wherein one rotating shaft 14 is transmission-connected to the first driving member 8; any first conveying component 11 comprises a first chain 15 and a plurality of first sprocket wheels 16, and the plurality of first sprocket wheels 16 are mounted on the plurality of rotating shafts 14 in a one-to-one correspondence, the first chain 15 is wound around the plurality of first sprocket wheels 16, and a plurality of first support rods 17 are detachably mounted between the two first chains 15, and first limit retaining rings 18 are spaced apart on the plurality of first support rods 17.

[0054] Specifically, Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, since a plurality of rotating shafts 14 are arranged at intervals along the height direction of the box body 7, and the plurality of rotating shafts 14 are arranged in a staggered layout, the first conveying assembly 11 and the second conveying assembly 12 can form a serpentine material conveying channel 13, and the structural design is simple and reasonable. Further, since a rotating shaft 14 is connected to the first driving member 8 in a transmission manner, the transmission connection between the rotating shaft 14 and the first driving member 8 can be a chain drive or a gear drive, etc., when the first driving member 8 is running, the rotating shaft 14 can be driven to rotate synchronously, thereby driving the entire conveying mechanism 9 to operate.

[0055] It can be understood that, since any first conveying assembly 11 includes the first chain 15 and a plurality of first sprockets 16, wherein the plurality of first sprockets 16 are mounted on the plurality of rotating shafts 14 in a one-to-one correspondence, and the first chain 15 is wound around the plurality of first sprockets 16, the first chain 15 can form a closed loop structure. When the rotating shaft 14 rotates under the action of the first driving member 8, the first sprocket 16 will drive the first chain 15 to rotate synchronously, thereby realizing the smooth conveyance of the material bag belt 100. Furthermore, since a plurality of first support rods 17 are detachably mounted between the two first chains 15, the detachable mounting method of the plurality of first support rods 17 and the first chains 15 can be threadedly connected, thereby facilitating the disassembly, assembly and replacement of the first support rods 17 and facilitating maintenance; at the same time, the material bag belt 100 can be supported by the plurality of first support rods 17, effectively preventing the material bag belt 100 from falling during the conveying process, and the plurality of first support rods 17 can form a hollow structure, thereby further increasing the contact area between the material bag belt 100 and the cold air, improving the cooling speed of the material bag belt 100, and realizing rapid cooling of the material bag belt 100. In addition, since two first limit rings 18 are arranged at intervals on the plurality of first support rods 17, the two sides of the material bag belt 100 can be limited, thereby improving the stability of the material bag belt 100 during the conveying process, and effectively preventing the material bag belt 100 from twisting and knotting.

[0056] In one embodiment, two groups of second conveying components 12 are also arranged at intervals on the plurality of rotating shafts 14, wherein any second conveying component 12 includes a second chain 19 and a plurality of second sprockets 20, the plurality of second sprockets 20 are installed one by one on the plurality of rotating shafts 14, the second chain 19 is wound around the plurality of second sprockets 20, and a plurality of second support rods 21 are detachably installed between the two second chains 19, and second limit rings 22 are arranged at intervals on the plurality of second support rods 21.

[0057] It is worth mentioning that since the feed channel through which the material bag belt 100 passes is a serpentine feed channel 13, when the material bag belt 100 is conveyed, the material bag belt 100 will be repeatedly rotated in a serpentine shape and the top and bottom surfaces of the material bag belt 100 will alternate with each other in spatial position. Therefore, in order to prevent the material bag belt 100 from falling downward or loosening during transportation and causing blockage, it is necessary to support or limit the top and bottom surfaces of the material bag belt 100 respectively by the first conveying component 11 and the second conveying component 12 to ensure the stability of the material bag belt 100 transportation.

[0058] Specifically, Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, since any second conveying assembly 12 includes a second chain 19 and a plurality of second sprockets 20, wherein the plurality of second sprockets 20 are also mounted on the plurality of rotating shafts 14 in a one-to-one correspondence, and the second chain 19 is wound around the plurality of second sprockets 20, the second chain 19 can also form a closed loop structure. When the rotating shaft 14 rotates under the action of the first driving member 8, the second sprocket 20 will rotate synchronously with the first sprocket 16, and thereby drive the second chain 19 and the first chain 15 to rotate synchronously, thereby ensuring the smooth conveyance of the material bag belt 100 in the serpentine feeding passage. Furthermore, since a plurality of second support rods 21 are detachably mounted between the two second chains 19, the detachable mounting method of the plurality of second support rods 21 and the second chain 19 can be threadedly connected, thereby facilitating the disassembly, assembly and replacement of the second support rods 21 and facilitating maintenance; at the same time, the material bag belt 100 can also be supported by the plurality of second support rods 21, effectively preventing the material bag belt 100 from falling during the conveying process, and the plurality of second support rods 21 can also form a hollow structure, thereby ensuring a rapid cooling effect on the material bag belt 100. In addition, since two second limit retaining rings 22 are arranged at intervals on the plurality of second support rods 21, the two sides of the material bag belt 100 can also be limited, thereby improving the stability of the material bag belt 100 during the conveying process.

[0059] In one embodiment, at least two groups of cooling mechanisms 10 are provided on one side of the box body 7, and any cooling mechanism 10 includes a shell 23, an infusion tube 24 and a plurality of fans. The shell body 23 is detachably mounted on one side of the box body 7 and is connected to the box body 7. An inlet 25 and an outlet 26 are provided on the shell body 23. The plurality of fans are arranged on the shell body 23 and are evenly and spaced apart along the extension direction of the shell body 23. The infusion tube 24 is located between the box body 7 and the plurality of fans. One end of the infusion tube 24 is connected to the refrigeration system 200, and the other end of the infusion tube 24 extends from the inlet 25 into the shell body 23, repeatedly bends in a serpentine shape, and then extends from the outlet 26 and is connected to the refrigeration system 200.

[0060] Specifically, Figure 4 , Figure 5 and Figure 7As shown, by providing at least two groups of cooling mechanisms 10 on one side of the box 7, it is possible to ensure that a more uniform and efficient cold air circulation is formed inside the box 7, improve the cooling effect, and each group of cooling mechanisms 10 can work independently, thereby avoiding the shutdown of the equipment caused by damage to a single cooling mechanism 10. Furthermore, since the shell 23 in the cooling mechanism 10 is detachably mounted on one side of the box 7 and is connected to the box 7, and a number of fans are arranged on the shell 23 and are evenly and spaced along the extension direction of the shell 23, the shell 23 can ensure the sealing between the box 7 and the fans, prevent cold air leakage, and by disassembling the shell 23, the staff can open the box 7 and maintain the first conveying assembly 11 and the second conveying assembly 12. It can be understood that since the shell 23 is provided with an inlet 25 and an outlet 26, and one end of the infusion tube 24 is connected to the refrigeration system 200, the other end of the infusion tube 24 extends from the inlet 25 into the shell 23, repeatedly bends in a serpentine shape, and then extends from the outlet 26 and is connected to the refrigeration system 200. Therefore, not only can the working medium in the refrigeration system 200 be transported to the shell 23 through the infusion tube 24, so as to be used in conjunction with a number of fans to output cold air into the box 7, but also the length and surface area of ​​the infusion tube 24 in the shell 23 are increased, so that the working medium in the infusion tube 24 can more fully exchange heat with the air inside the shell 23 during the flow process, thereby ensuring the cooling effect on the material bag 100.

[0061] In one embodiment, the bag stacking machine 3 includes a frame 27, a controller 28, and a guide mechanism and a bag stacking mechanism that are communicatively connected to the controller 28. The adjustment mechanism is arranged on one side of the frame 27 and corresponds to the discharge port 6. The guide mechanism is arranged on the top of the frame 27 and is used to pull the material bag belt 100 extended through the adjustment mechanism. The bag stacking mechanism is arranged at the bottom of the frame 27 and is used to place a storage box 29. The bag stacking mechanism can drive the storage box 29 to move to receive and stack the material bag belt 100 extended through the guide mechanism.

[0062] Specifically, Figure 1 , Figure 5 , Fig.10 and Fig.11As shown, since a controller 28 is provided on one side of the frame 27 in the bag stacking machine 3, the controller 28 can be implemented by an embedded system such as a PLC or a single-chip microcomputer, thereby enabling the bag stacking machine 3 to have an intelligent control function, that is, it can automatically adjust the working state of the bag stacking machine 3 according to preset parameters or external signals, and in order to facilitate the staff to set parameters and monitor the operating state of the bag stacking machine 3, the controller 28 is equipped with a human-machine interface (such as a touch screen) to display the current working state of the bag stacking machine 3, fault information and setting menu, etc. Furthermore, since the adjusting mechanism in the bag stacking machine 3 is arranged on one side of the frame 27 and corresponds to the discharge port 6, after the material bag belt 100 is cooled by the cooling device 4, the material bag belt 100 extends out through the discharge port 6 and is conveyed to the adjusting mechanism. The adjusting mechanism can be a tensioning wheel 31 or a roller that can be limitedly moved relative to the cooling device 4. The tensioning degree of the material bag belt 100 can be adjusted through the adjusting mechanism, so that the material bag belt 100 is always in a straight state during the entire conveying process, effectively preventing the material bag belt 100 from loosening, piling up or clogging in the bag stacking machine 3 due to the cooling device 4 or the excessively fast conveying speed of the package. It can be understood that after the material bag belt 100 is tensioned and adjusted by the adjustment mechanism, the material bag belt 100 is conveyed to the guide mechanism, and the guide mechanism can make the material bag belt 100 extend into the storage box 29 on the bag stacking mechanism along a predetermined path. Since the bag stacking mechanism can drive the storage box 29 to move, as the material bag belt 100 is continuously conveyed into the storage box 29, the bag stacking machine 3 drives the storage box 29 to move back and forth, thereby realizing automatic stacking and collection of the material bag belt 100 for subsequent transfer of the material bag belt 100. No manual operation is required by the staff, which reduces the labor intensity of the staff, improves the collection efficiency of the material bag belt 100 and the processing efficiency of the overall production process.

[0063] In one embodiment, the adjustment mechanism includes a trough body 30, a tensioning wheel 31 and a plurality of guide rollers 32. The tensioning wheel 31 and the plurality of guide rollers 32 are arranged at intervals in the trough body 30, and the tensioning wheel 31 can be limitedly moved relative to the plurality of guide rollers 32. An opening is provided at the top of the trough body 30 for the material bag belt 100 to extend into, so that the material bag belt 100 can bypass the tensioning wheel 31 and the plurality of guide rollers 32 and be transported to the guide mechanism.

[0064] Specifically, Figure 1 , Figure 5 , Fig.10 and Fig.11As shown, since an opening is provided at the top of the trough body 30 in the adjustment mechanism, the material bag belt 100 can be transported into the trough body 30 after extending from the discharge port 6 of the cooling device 4; at the same time, a tensioning wheel 31 and a plurality of guide rollers 32 are arranged at intervals in the trough body 30. The tensioning wheel 31 and the plurality of guide rollers 32 can ensure that the material bag belt 100 is wound along a predetermined path and transported into the guide mechanism after entering the trough body 30, and the structural design is simple and reasonable. Furthermore, since the tensioning wheel 31 can be limitedly moved relative to the plurality of guide rollers 32, that is, the tensioning wheel 31 can be moved up and down or left and right within a certain range relative to the plurality of guide rollers 32 in the trough body 30 to adapt to different tension requirements of the material bag belt 100 or compensate for the elongation or contraction of the material bag belt 100 during the transmission process; at the same time, the specific implementation method of the limited movement of the tensioning wheel 31 can adopt a waist-shaped groove and a support rod plug-in matching method, that is, waist-shaped grooves are opened on the side walls of both sides of the trough body 30, and the tensioning wheel 31 is rotatably installed on the support rod, and the two ends of the support rod are respectively passed through two waist-shaped grooves and threadedly connected with nuts. The staff can adjust the position of the support rod in the waist-shaped groove by screwing the nut, thereby adjusting the spatial position of the tensioning wheel 31 in the trough body 30, and realizing the tension adjustment of the material bag belt 100, which is simple and convenient to operate. In addition, the tensioning wheel 31 is used to keep the material bag belt 100 in a straight state at all times, and in cooperation with a number of guide rollers 32, it can effectively prevent the material bag belt 100 from twisting, knotting, etc. during transportation, thereby ensuring the stability and smoothness of the transportation of the material bag belt 100.

[0065] It is worth noting that, since the function of the guide roller 32 is to guide the material bag belt 100 to be transmitted along a predetermined path, the specific number of the guide rollers 32 and their installation positions should be determined according to the actual working conditions. Fig.10 As shown, in the present embodiment, the specific number of guide rollers 32 used in the adjustment mechanism is two, and the two guide rollers 32 are arranged symmetrically with respect to the center of the trough body 30 near the opening, and the tensioning wheel 31 is located between the two guide rollers 32 and arranged near the bottom of the trough body 30, thereby allowing the material bag belt 100 to smoothly bypass the tensioning wheel 31 and the two guide rollers 32 and then be transported to the guide mechanism, and the structural design is simple and reasonable.

[0066] In one embodiment, the guide mechanism includes a second driving member, two traction wheels 33 and a limiting plate 34, a plurality of limiting rollers 35 and a guide roller 36. The second driving member is arranged on the frame 27 and is used to drive the two traction wheels 33 to rotate toward each other. The plurality of limiting rollers 35 are located above the two traction wheels 33 and are arranged in an inverted trapezoidal shape. The two limiting plates 34 are arranged in an inverted cone shape and are located between the plurality of limiting rollers 35. The plurality of guide rollers 36 are located above the plurality of limiting rollers 35. The plurality of guide rollers 36 are spaced apart toward the trough body 30 along the height direction of the frame 27, and a baffle 37 is detachably installed at one end of the plurality of guide rollers 36 away from the frame 27. The plurality of guide rollers 36 and the limiting rollers 35 constitute a guide channel through which the feeding bag 100 passes.

[0067] Specifically, Figure 1 , Fig.10 , Fig.11 and Fig.12As shown, since the second driving member in the guide mechanism is arranged on the frame 27, the second driving member can also be a motor in the prior art, and the transmission connection mode between the two traction wheels 33 and the second driving member can be a gear transmission, etc., so that the two traction wheels 33 can rotate towards each other smoothly, and the two traction wheels 33 abut against the two sides of the material bag belt 100 to apply necessary traction to the material bag belt 100 and pull the material bag belt 100 to move on a predetermined path, so that the material bag belt 100 can be extended into the storage box 29 to complete automatic stacking. Further, since the upper part of the two traction wheels 33 is arranged in an inverted trapezoidal shape, the movement of the material bag belt 100 in the vertical direction can be limited, and the material bag belt 100 is prevented from deflecting or shaking during the transmission process, and the inverted trapezoidal arrangement helps to cooperate with a plurality of guide rollers 36 to form a stable guide channel, so that the material bag belt 100 can move close to the roller surface, thereby improving the stability of the material bag belt 100 during the transmission process. It can be understood that, since two limiting plates 34 are arranged in an inverted cone shape between the limiting rollers 35, the two limiting plates 34 can limit the feeding belt 100 in a narrower and more stable channel, and the inverted cone design helps to guide the belt 100 to smoothly enter between the two traction wheels 33 to complete the traction and conveying operation, and effectively reduce the jamming or blocking caused by the irregular shape or uneven tension of the belt 100, thereby improving the smoothness of the conveying of the belt 100. In addition, by arranging a plurality of guide rollers 36 above the limiting rollers 35 and arranging them at intervals toward the trough body 30 along the height direction of the frame 27, the conveying direction of the belt 100 can be adjusted, so that the belt 100 can smoothly transition to the limiting rollers 35, and the structural design is simple and reasonable; at the same time, by detachably installing the baffle plate 37 on the end of the guide roller 36 away from the frame 27, the belt 100 can be prevented from falling off the guide roller 36 during the conveying process. The baffle plate 37 and the guide roller 36 can be detachably installed in a threaded connection, that is, the staff can screw the baffle plate 37 in a direction away from or close to the frame 27 according to the width of the processed material bag belt 100, so as to shorten or extend the roller surface length of the corresponding guide roller 36 on which the material bag belt 100 is in contact, thereby being able to adapt to material bag belts 100 of different shapes and sizes and transport them stably, which is reliable to use.

[0068] In one embodiment, the bag stacking mechanism includes a transverse displacement platform 38 and a longitudinal displacement platform 39. The longitudinal displacement platform 39 is installed on the frame 27 for limited movement along its width direction, and the transverse displacement platform 38 is installed on the longitudinal displacement platform 39 for limited movement along its extension direction; a plurality of transverse positioning plates 40 and longitudinal positioning plates 41 are arranged in a rectangular row on the transverse displacement platform 38, and the plurality of transverse positioning plates 40 can be limitedly moved along the extension direction of the transverse displacement platform 38, and the plurality of longitudinal positioning plates 41 can be limitedly moved along the width direction of the transverse displacement platform 38.

[0069] Specifically, Figure 1 , Fig.10 and Fig.11 As shown, the driving mode of the limited movement of the transverse displacement platform 38 and the longitudinal displacement platform 39 in the bag stacking mechanism can be adopted as a cylinder, a hydraulic cylinder or a screw motor drive, so that the longitudinal displacement platform 39 can move relative to the frame 27 along its width direction, and the transverse displacement platform 38 can move relative to the longitudinal displacement platform 39 along its extension direction, and then can drive the storage basket on the transverse displacement platform 38 to move in the front and back and left and right directions, thereby facilitating the automatic stacking of the material bag belt 100, and the structural design is simple and reasonable. Furthermore, since a plurality of transverse positioning plates 40 and a plurality of longitudinal positioning plates 41 are arranged in a rectangular row on the transverse displacement platform 38, wherein the plurality of transverse positioning plates 40 can be limitedly moved along the extension direction of the transverse displacement platform 38, and the plurality of longitudinal positioning plates 41 can be limitedly moved along the width direction of the transverse displacement platform 38, the installation method of the plurality of transverse positioning plates 40 and the longitudinal positioning plates 41 and the transverse displacement platform 38 for limited movement can also be adopted in the manner of plugging and matching of waist-shaped grooves and locking columns (studs or screws), that is, the transverse displacement platform 38 is provided with a plurality of waist-shaped grooves on both sides along its extension direction and width direction, and the plurality of transverse positioning plates 40 and the longitudinal positioning plates 41 are installed on the transverse displacement platform 38 for limited movement by locking columns penetrated in the waist-shaped grooves, and the staff can adjust the installation positions of the plurality of transverse positioning plates 40 and the longitudinal positioning plates 41 by screwing the locking columns, so as to adapt to storage boxes 29 of different specifications and sizes, which is flexible and convenient to use.

[0070] In one embodiment, the guide assembly includes a plurality of directional rollers 42, and the plurality of directional rollers 42 are arranged at intervals on the support frame 1; a conveying device 43 is arranged on one side of the support frame 1 opposite to the packaging machine 2. Specifically, Figure 1 , Figure 2 , Figure 3 and Fig.10 As shown, by arranging a plurality of directional rollers 42 at intervals on the support frame 1, the material bag belt 100 that does not need to be cooled can be directly transported to the bag stacking machine 3 for stacking and collection, and the layout is simple and reasonable. Furthermore, by arranging a conveying device 43 on the side of the support frame 1 opposite to the packaging machine 2, the conveying device 43 can be a conveyor belt or a conveying platform in the prior art. When the storage box 29 is full of material bag belts 100, the staff can directly place the storage box 29 full of material bag belts 100 on the conveying device 43 for transportation and transfer, without the need for the staff to carry the storage box 29 over a long distance, thereby ensuring the continuity and smoothness of the overall processing flow and improving the production and processing efficiency.
