Description

Technical Field

[0001] The utility model relates to the field of heating bag processing equipment, in particular to a vertical heating bag machine for continuous conveying and sealing. Background Art

[0002] Existing heating bag machines are all flat and horizontally processed heating bag machines. However, the heating bag machine needs to go through a feeding station, a sealing station, and a cutting station. The length of its production line is relatively long, occupying a large amount of factory space. Moreover, traditional heating bag machines generally can only perform feeding, conveying, and sealing in a single row, and their processing efficiency is not high. When processed in a horizontal layout, the material can only be added and stacked on one layer of packaging fabric, and then the upper packaging fabric is sealed with the lower layer. This results in the inability to fill a single material bag with materials, and the weight of the material bag and the size of the packaging will be restricted. To solve the above problems, a vertical heating bag machine for continuous conveying and sealing is needed to realize the longitudinal conveyance of the fabric from top to bottom within the space of a single processing device, perform feeding, sealing, and cutting, and then send out the formed heating bag, which can take into account the use scenario of using higher-weight materials with smaller-sized packaging for heating bags.

[0003] Furthermore, during the heating bag sealing process, it takes a certain amount of time for the fabrics on both sides to come into contact and be sealed. The existing technical solutions all use the method of pausing the conveyance of the heating bag after it enters the heat sealing device and then continuing to convey the heating bag after the heat sealing is completed. This will result in a slower processing speed. To solve this problem, a heating bag machine is needed to realize non-stop sealing, that is, a vertical heating bag machine that realizes sealing during the conveyance of the fabric. Summary of the Invention

[0004] The utility model aims at the deficiencies in the prior art and provides a vertical heating bag machine for continuous conveying and sealing.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A vertical warm bag machine for continuous conveying and sealing, comprising a machine body. Fabrics are conveyed vertically relative to each other on the left and right sides. A feeding device, a first sealing mechanism, a longitudinal cutting mechanism and a transverse cutting mechanism are arranged on the machine body. The bottom of the feeding device is provided with a discharge port facing the opening between the fabrics on the left and right sides. The first sealing mechanism includes a transverse sealing member for horizontally sealing the bottom of the warm bag. A longitudinal sealing member for longitudinally sealing the warm bag is also provided on the machine body. The transverse cutting mechanism and the longitudinal cutting mechanism are respectively arranged below the transverse sealing member, and the longitudinal cutting mechanism is arranged below the longitudinal sealing member. The transverse sealing members on the left and right sides are connected with a sealing power source for driving them to close or separate. The first sealing mechanism is connected with a first following power source, and the first following power source drives the first sealing mechanism to move up and down. When the sealing power source drives the transverse sealing members to close and seal the fabric therebetween, the transverse sealing members move downward synchronously with the fabric at the same speed under the drive of the first following power source. Changing the traditional horizontally conveyed and processed warm bags to a vertical warm bag machine greatly saves the floor space required by the equipment. The meaning of integrating the transverse sealing member and the longitudinal sealing member into the first sealing mechanism is that no additional longitudinal sealing member and longitudinal sealing mechanism are provided. The transverse sealing member and the longitudinal sealing member are the same component, or the transverse sealing member and the longitudinal sealing member are different components installed on the first sealing mechanism, and the warm bag is horizontally and longitudinally sealed simultaneously in a single sealing. The drive of the first following power source makes the linear speed of the contact part between the transverse sealing member and the fabric the same as the downward conveying speed of the fabric, ensuring sufficient sealing time for good sealing effect, improving the packaging quality. At the same time, the fabric is sealed while being conveyed, realizing sealing without stopping the machine, and greatly improving the processing efficiency of the warm bag machine.

[0007] Preferably, the transverse sealing member and the longitudinal sealing member are integrally formed into a sealing plate, and the sealing plate is arranged on the first sealing mechanism; or the transverse sealing member and the longitudinal sealing member are respectively arranged horizontally and longitudinally on the first sealing mechanism. Integrating the transverse sealing member and the longitudinal sealing member into the first sealing mechanism completes the sealing of the side and bottom edges of the warm bag in one sealing, saving processing costs.

[0008] Preferably, a second sealing mechanism is further included. The second sealing mechanism is arranged above the first sealing mechanism. The transverse sealing member and the longitudinal sealing member are respectively arranged on the first sealing mechanism and the second sealing mechanism. The transverse sealing member is in the shape of a plate, and the longitudinal sealing member is a longitudinal sealing pressure wheel for longitudinally sealing the fabric. The longitudinal sealing pressure wheel is heated, and its peripheral surface thermally seals the longitudinally conveyed fabric, keeping the longitudinal direction of the warm bag in a thermally sealed state all the time with good thermal sealing effect.

[0009] Preferably, a lifting mounting frame is installed in the machine body, and at least one of the transverse cutting mechanism and the first sealing mechanism is installed on the lifting mounting frame.

[0010] Preferably, the lifting and mounting frame is connected with a lifting transmission mechanism, which includes a connecting seat, a connecting rod, a lifting power source, a nut, a screw rod, and a fixed seat. The nut is fixedly installed on the connecting seat and is threadedly connected with the screw rod. The screw rod is rotatably inserted into the fixed seat and axially fixedly connected with the fixed seat. The connecting rod is fixedly inserted into the connecting seat and is fixedly connected with the lifting and mounting frame. The output end of the lifting power source is connected with the screw rod and drives the screw rod to rotate, so that the connecting seat drives the lifting and mounting frame to move up and down. The second following power source is the lifting power source, or the first following power source is the lifting power source, or the first following power source and the second following power source are the same power source, and all are the lifting power source.

[0011] Preferably, the transverse cutting mechanism includes a cutting knife for transversely cutting the fabric. The cutting knife cuts the fabric through left-right extrusion cooperation or horizontal forward-backward movement. The transverse cutting mechanism further includes a knife holder for installing the cutting knife. The transverse cutting mechanism is connected with a second following power source, and the second following power source drives the transverse cutting mechanism to move up and down. When the transverse cutting mechanism cuts the fabric, the transverse cutting mechanism and the fabric move downward synchronously at the same speed.

[0012] Preferably, the transverse cutting mechanism and the first sealing mechanism are both installed on the lifting and mounting frame. The first following power source and the second following power source are the same power source, and both are the lifting power source. When the up-and-down position of the lifting and mounting frame in the machine body changes, it drives the transverse cutting mechanism and the first sealing mechanism to move up and down synchronously.

[0013] Preferably, the longitudinal cutting mechanism is located above the transverse cutting mechanism. The longitudinal cutting mechanism includes a cutting tool and a cutting pad. The cutting surface of the cutting tool is vertically arranged and perpendicular to the conveying surface of the fabric.

[0014] Preferably, it further includes a slitting and traction wheel for conveying the fabric. The slitting and traction wheel is arranged on the longitudinal cutting mechanism or above the longitudinal cutting mechanism. Since after the transverse sealing and longitudinal sealing are completed and the material is added, the fabric will be deformed to a certain extent, which will affect the straightness of the subsequent fabric. Therefore, the slitting and traction wheel is set to guide the conveying of the fabric before the fabric enters the longitudinal cutting mechanism, so that the transverse and longitudinal conveying of the fabric remains straight. During slitting, the straightness of the tangent line is maintained, especially for guiding the front and rear sides of the fabric, so that it will not be skewed, thus making the product more beautiful.

[0015] Preferably, a material shaking part is arranged below the first sealing mechanism. The material shaking part is connected with a material shaking power source, and the material shaking power source drives the material shaking part to reciprocate horizontally to drive the fabric to shake. A small movement of the material shaking power source can shake off the powder on the fabric, avoiding the powder sticking to the upper part of the warm package and affecting the sealing effect or the appearance of the product.

[0016] Preferably, a metering feeder is installed above the machine body. A number of nozzles are arranged below the metering feeder. The discharge ports of the nozzles correspond to the feeding ports between the fabrics one by one. The metering feeder is fed through a vibrating feeder, and the nozzle is connected to a power source that drives it to vibrate. It is convenient for feeding, the feeding time can be automatically controlled, which is convenient for the quality of the materials added to each material bag to be unified. The vibrating power source can ensure that after each feeding, the materials in the nozzle enter between the fabrics, thus ensuring the consistency of each feeding amount and improving the product quality control.

[0017] Due to the adoption of the above technical solutions, the utility model has remarkable technical effects:

[0018] Adopting a vertical structure, the fabric is longitudinally conveyed from top to bottom for processing of each process, simplifying the production process and improving the space utilization rate;

[0019] The vertical warm bag machine can take into account the use scenarios of packaging high-gram-weight materials with smaller sizes for warm bags, reducing the gram weight limit and packaging size limit of traditional single warm bags;

[0020] The transverse sealing member moves downward together with the downward conveyance of the fabric, increasing the heat sealing time, thereby improving the sealing quality and the finished product rate;

[0021] The transverse cutting mechanism moves downward together with the downward conveyance of the fabric, keeping the cutting knife synchronized with the fabric in the vertical direction during transverse cutting, resulting in a higher cutting finished product rate and neater cutting edges;

[0022] Realize non-stop sealing, overcome the efficiency loss caused by the traditional stop sealing method, and improve the overall production efficiency;

[0023] The transverse sealing member and the transverse cutting mechanism can be lifted and lowered synchronously, and the lifting and lowering method can be realized by means of full-automatic control. While synchronizing the transverse sealing and transverse cutting, it is also convenient for the staff to adjust the heights of different mechanisms during the processing of warm bags of different specifications.

Detailed implementation manners

[0032] The present utility model will be further described in detail below in conjunction with the drawings and embodiments. Embodiment

[0033] A vertical warm bag machine for continuous conveying and sealing, as Figures 1 - 3As shown in the figure, it includes a machine body 1. The fabrics on the left and right sides are conveyed vertically opposite to each other, and a feeding port 11 for adding materials is formed between the fabrics on the left and right sides. A feeding device 8, a first sealing mechanism 2, a longitudinal cutting mechanism 5 and a transverse cutting mechanism 4 are arranged on the machine body 1. The bottom of the feeding device 8 is provided with a discharge port facing the opening between the fabrics on the left and right sides. The first sealing mechanism 2 includes a transverse sealing member 21 for transversely sealing the bottom of the warm package. A longitudinal sealing member for longitudinally sealing the warm package is also arranged on the machine body 1. Both the transverse cutting mechanism 4 and the longitudinal cutting mechanism 5 are arranged below the transverse sealing member 21. The transverse sealing members 21 on the left and right sides are connected with a sealing power source 23 that drives them to close or separate. The first sealing mechanism 2 is connected with a first following power source 22, and the first following power source 22 drives the first sealing mechanism 2 to move up and down. When the sealing power source 23 drives the transverse sealing members 21 to close and seal the fabric between them, the transverse sealing members 21 move downward synchronously with the fabric at the same speed under the drive of the first following power source 22. The traditional horizontally conveyed and processed warm package is changed to a vertical warm package machine, greatly saving the floor space required by the equipment. The meaning that the transverse sealing member and the longitudinal sealing member are integrally integrated in the first sealing mechanism is that no additional longitudinal sealing member and longitudinal sealing mechanism are provided. The transverse sealing member and the longitudinal sealing member are the same component, or the transverse sealing member and the longitudinal sealing member are different components installed on the first sealing mechanism, and the warm package is transversely and longitudinally sealed simultaneously in a single sealing. The drive of the first following power source makes the linear speed of the contact part between the transverse sealing member and the fabric the same as the downward conveying speed of the fabric, ensuring sufficient sealing time for good sealing effect, improving the packaging quality. At the same time, the fabric is sealed while being conveyed, realizing non-stop sealing, and greatly improving the processing efficiency of the warm package machine. The sealing power source 23 drives the transverse sealing member 21 to move horizontally, which can be a technical solution well known to those skilled in the art such as a motor, a cylinder, an electric cylinder, etc.

[0034] It further includes a second sealing mechanism 7. The second sealing mechanism 7 is arranged above the first sealing mechanism 2. The transverse sealing member 21 and the longitudinal sealing member are respectively arranged on the first sealing mechanism 2 and the second sealing mechanism 7. The transverse sealing member 21 is in a plate shape, and the longitudinal sealing member is a longitudinal sealing pressure wheel 71 for longitudinally sealing the fabric.

[0035] A lifting mounting frame 3 is installed inside the machine body 1, and at least one of the transverse cutting mechanism 4 and the first sealing mechanism 2 is installed on the lifting mounting frame 3.

[0036] Such as Figure 4As shown in the figure, the lifting and mounting frame 3 is connected to a lifting drive mechanism. The lifting drive mechanism includes a connecting seat 61, a connecting rod 62, a lifting power source, a nut 64, a screw rod 65, and a fixed seat 66. The nut 64 is fixedly installed on the connecting seat 61 and is threadedly connected to the screw rod 65. The screw rod 65 is rotatably passed through the fixed seat 66 and is axially fixedly connected to the fixed seat 66. The connecting rod 62 is fixedly passed through the connecting seat 61, and the connecting rod 62 is fixedly connected to the lifting and mounting frame 3. The output end of the lifting power source is connected to the screw rod 65 and drives the screw rod 65 to rotate so that the connecting seat 61 drives the lifting and mounting frame 3 to move up and down. The second following power source 63 is the lifting power source, or the first following power source 22 is the lifting power source, or the first following power source 22 and the second following power source 63 are the same power source, and all are the lifting power source.

[0037] The cross-cutting mechanism 4 includes a cutting knife 41 for horizontally cutting the fabric. The cutting knife 41 cuts the fabric through left and right extrusion cooperation or horizontal forward and backward movement. The cross-cutting mechanism 4 further includes a tool holder 42 for mounting the cutting knife. The cross-cutting mechanism 4 is connected to a second following power source 63. The second following power source 63 drives the cross-cutting mechanism 4 to move up and down. When the cross-cutting mechanism 4 cuts the fabric, the cross-cutting mechanism 4 and the fabric move downward synchronously at the same speed. The figure shows the case of cutting by the cooperation of left and right cutting tools. The horizontal forward and backward movement is to cut by using a flying knife arranged on the guide rail. Both of these two methods are conventional settings for those skilled in the art and will not be elaborated here.

[0038] In this embodiment, the longitudinal cutting mechanism 5 is located above the cross-cutting mechanism 4. The longitudinal cutting mechanism 5 includes a cutting tool 51 and a cutting pad 52. The cutting surface of the cutting tool 51 is vertically arranged and perpendicular to the conveying surface of the fabric. As other embodiments, the cross-cutting mechanism 4 can be arranged above the longitudinal cutting mechanism 5. It also includes a cutting traction wheel for conveying the fabric. The cutting traction wheel is arranged on the longitudinal cutting mechanism 5 or above the longitudinal cutting mechanism 5. If it is arranged on the longitudinal cutting mechanism 5, the cutting traction wheel can be arranged parallel to the cutting tool and the cutting pad. As other embodiments, it can be arranged above the longitudinal cutting mechanism 5 to guide the conveying of the fabric before the fabric enters the longitudinal cutting mechanism.

[0039] As Figure 5 shown, a vibrating part 9 is arranged below the first sealing mechanism 2. The vibrating part 9 is connected to a vibrating power source 91. The vibrating power source 91 drives the vibrating part 9 to reciprocate horizontally to drive the fabric to vibrate.

[0040] A metering and feeding device 81 is installed above the machine body 1. A plurality of nozzles 82 are arranged below the metering and feeding device 81. The discharge ports of the nozzles 82 correspond to the feeding ports between the nozzles and the fabric one by one. The metering and feeding device 81 is fed through a vibrating feeder 83.

[0041] The working principle is as Figure 6As shown in the figure: The two rolls of fabric on the left and right are conveyed relatively left and right through a number of conveying rollers, and a feeding port 11 with a larger upper part and a smaller lower part is formed below the feeder 82, which is convenient for feeding. When the fabric enters the machine body, it is located above any sealing mechanism and below the nozzle. The materials in the warm package added in the metering feeder are respectively fed into the space between the lower fabrics through the nozzle.

[0042] The order of longitudinal sealing and transverse sealing can be reversed. However, to achieve a better sealing effect, longitudinal sealing is carried out first. The longitudinal sealing rollers 71 on the left and right sides are used for longitudinal sealing. The longitudinal sealing rollers 71 press and seal the fabric between them. During the longitudinal conveyance of the fabric from top to bottom, the fabric fully contacts the peripheral surface of the longitudinal sealing rollers 71 to achieve sealing. Then, transverse sealing is carried out. When the plate-shaped transverse sealing member closes from left to right, the bottom of the fabric is sealed. At this time, the nozzle can be controlled for feeding. At the same time, the first following power source 22 drives the transverse sealing member 21 to move downward. The fabric continues to be conveyed downward, and the conveying speed of the fabric is consistent with the downward movement speed of the transverse sealing member 21. Since the transverse sealing member 21 has sufficient contact time with the fabric, the heat sealing effect can be improved, thereby improving the product quality. The first following power source 22 can be started before the sealing power source 23 is started. The purpose is to accelerate the transverse sealing member 21 to reach the conveying speed of the fabric and then perform the action of clamping and sealing the fabric, ensuring that the transverse sealing member and the fabric always maintain synchronous movement during the contact process.

[0043] After the feeding is completed, the transverse sealing member 21 separates from left to right and leaves the fabric. The first following power source 22 drives the transverse sealing member 21 to move upward to the initial position, which is located at the bottom of the next warm package, and then repeats the operation.

[0044] The fabric is conveyed to the longitudinal cutting mechanism 5 and the transverse cutting mechanism 4 for cutting. The longitudinal cutting mechanism cuts open the fabrics conveyed downward along the way to form multiple columns of warm packages. In the figure, three columns of warm packages are processed. In fact, it can be two columns, four columns or more columns, and the processing efficiency of the warm packages can be improved according to requirements. The transverse cutting mechanism 4 adjusts the transverse cutting position according to the size of the warm package. A fine adjustment nut is provided below it, which can adjust the up and down position of the transverse cutting mechanism. Thus, it can adapt to different specifications of warm packages. Because when the specification of the warm package changes, the position of each heat sealing needs to be adjusted, and thus the position of the lower transverse cutting mechanism also needs to be adjusted accordingly. Since the lifting of the transverse cutting mechanism and the first transverse cutting mechanism 4 is synchronous, no additional adjustment is required, and only the transverse cutting position needs to be slightly adjusted according to the warm package specification. After the adjustment is completed, the cutting time of the transverse cutting mechanism 4 is set through the time interval operation to cut open the bottom of the warm package from the upper warm package to achieve separation. Subsequently, the warm packages are sent out through a conveyor belt or other conveying methods for collection or the next process.

[0045] The lifting and mounting frame 3 is connected with a lifting transmission mechanism to achieve lifting. When the first sealing mechanism 2 is separately mounted on the lifting and mounting frame 3, the first following power source 22 and the second following power source 63 are the same power source, both being the lifting power source. When the cross-cutting mechanism 4 is separately mounted on the lifting and mounting frame 3, the lifting of the lifting and mounting frame 3 drives the cross-cutting mechanism 4 to lift. The lifting power source and the first following power source 22 are different power sources, and the lifting power source and the second following power source 63 are the same power source. When both the cross-cutting mechanism 4 and the first sealing mechanism 2 are mounted on the lifting and mounting frame 3, the lifting power source and the first following power source 22 are the same power source. When the vertical position of the lifting and mounting frame 3 in the machine body 1 changes, it drives the cross-cutting mechanism 4 and the first sealing mechanism 2 to lift synchronously.

[0046] The lifting transmission mechanism is used to drive the vertical position of the lifting and mounting frame 3. After the parameters of the heat pack specifications are input, the lifting power source drives the screw rod 65 to rotate through direct connection or through methods such as gear transmission, synchronous pulley and synchronous belt transmission. The screw rod 65 is axially fixed relative to the fixed seat 66, and the fixed seat is relatively fixed to the machine body 1. Then, the rotation of the screw rod 65 drives the nut 64 to lift along the axis. The movement of the nut 64 drives the connecting seat 61 to lift and the connecting rod 62 on the connecting seat 61 to lift. The lifting of the connecting rod 62 causes the lifting and mounting frame 3 above it to also lift. Thus, precise speed and position control on the lifting and mounting frame 3 are achieved.

[0047] The lifting power source is generally a servo motor, and can also be other common power sources in the field such as electric cylinders. In this embodiment, the attached reference numerals of the first following power source 22 and the second following power source 63 are the same power source. The lifting transmission mechanism is used to make the horizontal sealing member 21 lift to achieve that the descending speed of the horizontal sealing member 21 is consistent with the fabric conveying speed. In fact, the first following power source 22 can also be separately arranged from the second following power source 63, so that the second following power source 63 drives the lifting and mounting frame 3 for position adjustment, and the first following power source 22 separately drives the horizontal sealing member to lift.

[0048] Another implementation method is that the first sealing mechanism 2 is installed on the connecting rod 62 through a linear bearing. Driven by the first following power source 22, the first sealing mechanism 2 can slide up and down along the connecting rod 62. This can make the movement of the first sealing mechanism 2 out of sync with that of the cross-cutting mechanism. Embodiment

[0049] Basically the same as Embodiment 1, the difference is that, as Figure 7As shown, the transverse sealing member 21 and the longitudinal sealing member are integrally integrated in the first sealing mechanism 2. In one solution, the transverse sealing member 21 and the longitudinal sealing member are integrally formed into a sealing plate 24, and the sealing plate 24 is arranged on the first sealing mechanism 2 and is used for transversely and longitudinally sealing the fabric at the same time. Or in another solution, the transverse sealing member 21 and the longitudinal sealing member are arranged on the first sealing mechanism 2 in a transverse and a longitudinal manner respectively, and move synchronously under the drive of the sealing power source 23 to seal the fabric. The longitudinal cutting mechanism 5 is arranged below the transverse sealing member 21 for longitudinally sealing the heat preservation bag.

[0050] The working principle is basically the same as that of Embodiment 1, and the difference lies in that: in order to make the sealing effect better, the longitudinal sealing and the transverse sealing are carried out synchronously. The transverse sealing members close together from left and right to press the fabric between them, so that the sides and the bottom of the fabric are all sealed. At this time, the material nozzle can be controlled to feed materials. During the process of the fabric being longitudinally conveyed from top to bottom, the first following power source 22 drives the transverse sealing member 21 to move downward. The fabric continues to be conveyed downward, and the conveying speed of the fabric is consistent with the descending speed of the transverse sealing member 21. At the same time, the fabric is heat-sealed longitudinally and transversely. Since the transverse sealing member 21 has sufficient contact time with the fabric, the heat-sealing effect can be improved, thereby improving the product quality. After the feeding is completed, the transverse sealing member 21 separates from left and right and leaves the fabric. The first following power source 22 drives the transverse sealing member 21 to move upward to the initial position, which is at the bottom of the next heat preservation bag, and then repeats the operation.
