Technical Field

[0001] The invention relates to the technical field of mesh bag forming, in particular to a mesh bag forming machine. Background Art

[0002] A mesh bag is a mesh pocket woven with thread for storing things and is widely used in people's daily life.

[0003] The end of the mesh bag is usually composed of a mesh bag body and a strap. Both the mesh bag body and the strap are plastic parts. The mesh bag body has a slender strip-shaped opening. One end of the strap extends into the opening of the mesh bag body. The mesh bag body and the strap are usually fixedly connected using heat sealing technology. The other end of the strap extends outside the mesh bag body to facilitate the carrying of the mesh bag.

[0004] In the prior art, when producing the ends of mesh bags, manual methods are usually adopted, in which the mesh bag body and the strips are assembled one by one, and one end of the strip is inserted into the opening of the mesh bag body and then heat-sealed. When the above production method is adopted, on the one hand, the labor cost and the workload of the production workers are increased, and on the other hand, the production efficiency is low, and it is difficult to achieve large-scale production. In addition, under the manual processing mode, there are differences in the product quality of the mesh bags, and defective products are easily produced due to the negligence of workers during production, resulting in material waste and reducing the overall quality of batch products.

[0005] Therefore, it is necessary to provide an automated mesh bag forming machine. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects in the prior art and provide a mesh bag forming machine that reduces labor costs, alleviates the burden on workers, is suitable for batch production and reduces the differences between products to ensure the overall quality of batch products.

[0007] In order to achieve the above technical effects, the technical solution of the present invention is: a mesh bag forming machine, comprising:

[0008] frame;

[0009] A conveying member, wherein the conveying member has an adsorption surface for adsorbing the mesh bag body, the adsorption surface is provided with a negative pressure hole for connecting to a first negative pressure device, the conveying member is connected to a transmission device, the transmission device is used to drive the conveying member to move back and forth, the movement path of the conveying member includes a processing position and a feeding position, and the opening of the mesh bag body adsorbed on the conveying member is perpendicular to the movement direction of the conveying member;

[0010] A tape inserting and cutting device, which is used to insert the end of the tape into the opening of the net bag body on the adsorption surface of the conveyor at the processing position and then cut the portion of the tape located outside the net bag body;

[0011] A processing device, the processing device includes a suction cup, a heat sealing member, a first movable component that drives the suction cup to move, and a second movable component that drives the heat sealing member to move. The moving directions of the suction cup and the heat sealing member are parallel and both face the mesh bag body on the processing position conveyor. The suction cup is used to connect to the second negative pressure device. The first movable component cooperates with the suction cup to increase the opening width of the mesh bag body. The second movable component cooperates with the heat sealing member to heat-seal the mesh bag body and the strip inserted into the opening of the mesh bag body.

[0012] When the mesh bag forming machine of the above technical solution is in use, the conveying device moves the conveying member to the feeding position, the mesh bag body with a slender strip opening is placed on the conveying surface of the conveying member, and the first negative pressure device is used to generate negative pressure at the negative pressure hole to attract the mesh bag body to be adsorbed on the conveying member; then the conveying device moves the conveying member to the processing position, and the first moving component drives the suction cup to move downward, so that the suction cup approaches the side of the mesh bag body away from the adsorption surface, the second negative pressure device is started, and then the moving component drives the suction cup to move away from the adsorption surface, so that the opening of the mesh bag body opens , that is, increase the width of the opening of the mesh bag body; then the tape cutting device is started, and after the bottom end of the tape is inserted into the opening of the mesh bag body, the tape is cut on the outside of the mesh bag body; then the second moving component is started, driving the heat sealing member to move downward, bringing the two sides of the mesh bag body closer to each other, while the first negative pressure device and the second negative pressure device stop running, and the two sides of the mesh bag body are close to each other. Under the heating state of the heat sealing member, the two sides of the mesh bag body and the two sides of the cut tape are hot-melt-bonded together, thereby forming a one-piece product, which is then collected by workers. Compared with the manual production method used in the prior art, the present invention can automatically realize the opening, tape insertion and heat sealing operations of the mesh bag body, with a high degree of automation, which reduces the workload of workers, reduces labor costs, improves production efficiency, and has small differences between products, thereby ensuring the quality of batch products in terms of technology suitable for mass production.

[0013] Preferably, the inserted tape cutting device includes a movable clamping assembly and a cutting assembly, the movable clamping assembly includes a clamping assembly for clamping the end of the tape and a third movable assembly for driving the clamping assembly to reciprocate between a clamping position and a release position, the release position is located between the cutting assembly and the processing position, the clamping position is located on the side of the cutting assembly away from the processing position, and the cutting assembly is used to cut the tape.

[0014] By adopting the above technical solution, the third moving component drives the clamping component to move back and forth between the clamping position and the release position. When the clamping component moves to the clamping position, the clamping component clamps the mesh belt, and then the third moving component drives the clamping component to move to the release position, so that the end of the clamped strip extends into the opening of the mesh bag body on the conveyor at the processing position and maintains the clamped state. The strip is cut by the cutting component, and then the second moving component drives the strip to move, and heat-seals the mesh bag body and the strip. After the two are heat-sealed and formed, the clamping component releases the cut strip, and then the third moving component drives the clamping component to move to the clamping position, and the above operation is repeated.

[0015] Preferably, at least two adsorption areas are provided on the adsorption surface along the moving direction of the conveyor, the negative pressure holes are provided on the adsorption areas, and the number of the cutting components, the number of the suction cups and the number of the adsorption areas are equal and corresponding.

[0016] By adopting the above technical solution, the number of negative pressure holes, cutting components and suction cups is increased, so that the device can perform one-to-one heat sealing processing on multiple mesh bag bodies and multiple strips at one time, thereby greatly improving production efficiency.

[0017] Preferably, the cutting assembly includes a first downward pneumatic scissors and a second upward pneumatic scissors, the shell of the first pneumatic scissors and the shell of the second pneumatic scissors are both fixed on the frame, the movable shaft of the first pneumatic scissors is connected to the first upper pressure plate, and the movable shaft of the second pneumatic scissors is connected to the first lower support plate, and before the first pneumatic scissors and the second pneumatic scissors cut the strip, the first upper pressure plate and the first lower support plate clamp the strip.

[0018] By adopting the above technical solution, the cutting component is divided into two parts, a first pneumatic scissor and a second pneumatic scissor. The first pneumatic scissor cuts the strip downwards, and the second pneumatic scissor cuts the strip upwards. Since the first pneumatic scissor is connected to the first upper pressure plate and the second pneumatic scissor is connected to the second lower support plate, before cutting, that is, before the blades of the first pneumatic scissors and the second pneumatic scissors touch the strip, the first upper pressure plate and the second lower support plate can clamp the strip so that the strip is relatively fixed, so as to achieve smooth cutting of the strip and ensure that the strip is cut to a fixed length at the same time to avoid inconsistent cutting lengths, thereby improving product quality.

[0019] Preferably, the first upper pressing plate and / or the first lower supporting plate are connected with elastic members to increase the clamping force of the first upper pressing plate and the first lower supporting plate on the belt strip.

[0020] By adopting the above technical solution, before the first pneumatic scissors and the second pneumatic scissors cut the strip, the first upper pressing piece and the first lower supporting piece approach each other and clamp the strip, and through the elastic deformation of the elastic piece, an elastic force is applied between the first upper pressing piece and the first lower supporting piece, thereby increasing the clamping force and achieving the effect of further fixing the strip, preventing the position of the strip from loosening during the cutting process, affecting the cutting quality, and further leading to the production of defective products.

[0021] Preferably, the clamping assembly includes a clamping frame connected to the output end of the third moving assembly, and the clamping frame is provided with a second upper pressing plate, a second lower supporting plate and a distance adjustment assembly for adjusting the second upper pressing plate and the second lower supporting plate.

[0022] By adopting the above technical solution, the third moving component can be used to drive the clamping frame to move, thereby driving the second upper pressure plate and the second lower support plate to move, so that the clamping member, the second upper pressure plate and the second lower support plate can move back and forth between the clamping position and the release position. The distance between the second upper pressure plate and the second lower support plate can be adjusted by the adjustment component. When the two are close to each other, the strip can be clamped, and when the two are away from each other, the strip can be loosened, which makes it convenient for workers to collect the heat-sealed products.

[0023] Preferably, the frame is further provided with a material passing through hole, which is adapted to the cross-section of the strip, and the material passing through hole is arranged on a side of the clamping assembly away from the processing position.

[0024] By adopting the above technical solution, when the tape inserting and cutting device is in operation, the tape passes through the material passing hole, and the material passing hole is used to prevent the position of the tape from shifting. After the tape is clamped by the clamping assembly, the tape is driven to move so that one end of the tape is inserted into the opening of the mesh bag body for heat sealing.

[0025] Preferably, a guide assembly is further provided on the side of the feed through hole away from the processing position, and the guide assembly is used to guide the strip to pass through the inner side of the feed through hole in a direction perpendicular to the opening of the feed through hole.

[0026] By adopting the above technical solution, the guide component can guide the feeding direction of the strip so that it remains perpendicular to the opening of the feed hole to ensure stable feeding and supply of the strip, which is conducive to the clamping component clamping the strip in the clamping position.

[0027] Preferably, the guide assembly includes a third upper pressing plate and a third lower supporting plate arranged directly below the third upper pressing plate, and the third upper pressing plate is clearance-fitted with the third lower supporting plate and loosely fits with the belt strip.

[0028] By adopting the above technical solution, the third upper pressure plate and the third lower support plate with clearance fit cooperate with each other to limit the feeding direction of the strip before passing through the through hole, so as to ensure that the strip is fed in a direction perpendicular to the opening of the through hole, thereby achieving stable feeding and supplying.

[0029] Preferably, one of the third upper pressure plate and the third lower support plate is a movable part, and the other is a fixed part. The fixed part is connected to a guide rod extending in a vertical direction. The movable part is sleeved outside the guide rod and slides with the guide rod. The guide rod is threadedly connected to a screw sleeve, and the movable part is arranged between the fixed part and the screw sleeve.

[0030] By adopting the above technical solution, the gap between the third upper pressure plate and the third lower support plate can be adjusted, so that it is suitable for strips of different thicknesses. The guide rod is used to guide the moving direction of the movable part, and the screw sleeve is used to make the movable part located between the fixed part and the screw sleeve, so that the gap width is adjusted to be suitable for strips of different thicknesses.

[0031] Preferably, there are two of each of the conveying member, the tape cutting device and the processing device, and the tape cutting device corresponds to the processing device one by one. The conveying member is spaced apart along its own moving direction, and the two conveying members are respectively the first conveying member and the second conveying member. The transmission device drives the first conveying member and the second conveying member to move synchronously. When the first conveying member moves to its corresponding processing position, the second conveying member moves to its corresponding feeding position. When the first conveying member moves to its corresponding feeding position, the second conveying member moves to its corresponding processing position.

[0032] By adopting the above technical solution, the number of conveying parts, tape inserting and cutting devices and processing devices is increased. When the feeding operation is performed on one of the conveying parts, the device starts to control the action of the tape inserting and cutting device and the processing device corresponding to the other conveying part, so as to insert the tape into the opening of the mesh bag body on the other conveying part and perform cutting and heat sealing, thereby greatly improving the production efficiency.

[0033] Preferably, the feeding position of the first conveying member coincides with the feeding position of the second conveying member.

[0034] By adopting the above technical solution, workers only need to provide the mesh bag body to the first conveyor or the second conveyor at the same position, which is conducive to improving production efficiency, while enhancing the overall structural compactness of the device and saving production space.

[0035] To sum up, compared with the prior art, the mesh bag forming machine of the present invention drives the conveying member with negative pressure holes to move through the transmission device to realize the transmission of the mesh bag body, cooperates with the first moving component and the suction cup to increase the width of the opening of the mesh bag body, and inserts the end of the strip into the opening of the mesh bag body and cuts it by the strip insertion and cutting device, and then drives the strip to move through the second moving component to realize the heat sealing forming of the mesh bag body and the strip, which reduces the burden on workers, reduces labor costs, improves production efficiency, and is suitable for mass production while ensuring product quality.

[0056] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0057] like Figures 1-19 As shown, the mesh bag forming machine of the present invention comprises:

[0058] Rack 300;

[0059] The conveying member 400 has an adsorption surface 401 for adsorbing the net bag body 100. The adsorption surface 401 is provided with a negative pressure hole 402 for connecting to a first negative pressure device. The conveying member 400 is connected to a transmission device, which is used to drive the conveying member 400 to move back and forth. The movement path of the conveying member 400 includes a processing position and a feeding position. The opening of the net bag body 100 adsorbed on the conveying member 400 is perpendicular to the movement direction of the conveying member 400.

[0060] The tape inserting and cutting device is used to insert the end of the tape strip 200 into the opening of the net bag body 100 on the adsorption surface 401 of the conveying member 400 at the processing position, and then cut the portion of the tape strip 200 outside the net bag body 100;

[0061] The processing device includes a suction cup 500, a heat sealing member 600, a first movable assembly 700 for driving the suction cup 500 to move, and a second movable assembly 800 for driving the heat sealing member 600 to move. The moving directions of the suction cup 500 and the heat sealing member 600 are parallel and both face the mesh bag body 100 on the processing position conveying member 400. The suction cup 500 is used to connect to the second negative pressure device. The first movable assembly 700 cooperates with the suction cup 500 to increase the opening width of the mesh bag body 100. The second movable assembly 800 cooperates with the heat sealing member 600 to heat-seal the mesh bag body 100 and the strip 200 inserted into the opening of the mesh bag body 100.

[0062] When the mesh bag forming machine of the invention is used, the conveying member 400 is driven by the transmission device to move, so that the conveying member 400 moves back and forth between the processing position and the feeding position. The worker only needs to move the mesh bag body 100 (the specific structure of the mesh bag body 100 in the prior art is as shown in FIG. Figure 12As shown, the mesh bag body 100 usually has an elongated opening, and the mesh bag body 100 is a soft plastic part) is placed on the adsorption surface 401 of the conveying member 400, and the opening of the mesh bag body 100 faces the bag insertion and cutting device. The first negative pressure device (usually a negative pressure pump) is started to extract the air in the negative pressure hole 402, so that the opening position of the negative pressure hole 402 maintains a negative pressure state, so as to firmly adsorb the mesh bag body 100; the first negative pressure device keeps working continuously, and the conveying member 400 is moved to the adding position through the transmission device. After the working position is reached, the first moving component 700 drives the suction cup 500 to move closer to the mesh bag body 100, so that the suction cup 500 is adjacent to or even in contact with the side of the mesh bag body 100 away from the conveying member 400, and then the second negative pressure device is started to extract the air in the suction cup 500, so that the inside of the suction cup 500 maintains a negative pressure, firmly adsorbing the mesh bag body 100, and then the first moving component 700 drives the suction cup 500 away from the adsorption surface 401, thereby increasing the width of the opening of the mesh bag body 100 to facilitate the insertion of the strip 200.

[0063] After the opening of the mesh bag body 100 widens, the insert-and-cut device activates, gripping the strip 200 and inserting the end of the strip 200 into the opening of the mesh bag body 100. The insert-and-cut device then cuts the strip 200. The second moving assembly 800 in the processing device then drives the heat-sealing element 600 toward the mesh bag body 100. The heat-sealing element 600, which contains a built-in electric heating strip and maintains a continuously energized, high-temperature state, locks the mesh bag body 100 and the cut strip 200 onto the suction surface 401 of the conveyor 400. By heating the mesh bag body 100 and the strip 200, the mesh bag body 100 and the strip 200 are heat-sealed and integrated into a single piece, forming the mesh bag product. During the heat-sealing process, the first and second negative pressure devices are deactivated to save energy. After the heat-sealing is complete, the worker removes the mesh bag product.

[0064] Compared with the prior art, in the mesh bag forming machine of the present invention, the first negative pressure device forms negative pressure at the negative pressure hole 402 on the adsorption surface 401 of the conveying member 400, so as to firmly adsorb the mesh bag body 100, cooperate with the transmission device to drive the mesh bag body 100 to move, and drive the suction cup 500 to move through the first moving component 700, while the suction cup 500 maintains negative pressure to increase the opening width of the mesh bag body 100, so that the tape cutting device inserts the tape 200 into the opening of the mesh bag body 100 for cutting, and then drives the heat sealing member 600 to move through the second moving component 800 to complete the heat sealing forming of the product, reducing manual operation, alleviating the burden on workers, reducing labor costs, and improving production efficiency at the same time, which is conducive to batch manufacturing of products. Not only that, the differences between the heat-sealed products are small, reducing the defective rate caused by manual negligence, thereby improving production quality.

[0065] The specific structure of the rack 300 is as follows: Figure 1-Figure 3 As shown, the frame 300 includes a first frame body 301 and a second frame body 302, wherein the first frame body 301 is used to install the processing device and the transmission device, and the second frame body 302 is used to install the tape inserting and cutting device.

[0066] The specific structure of the transmission device is as follows Figure 4 、 Figure 7 and Figure 8 As shown, the transmission device is long and narrow, and belongs to a synchronous belt module linear guide rail, specifically including a first transmission frame 260 and a first motor 210, the first transmission frame 260 and the first motor 210 are both fixedly connected to the first frame body 301, and a first synchronous belt 250 is provided on the first transmission frame 260, and the first motor 210 is connected to the first driving wheel 230 through the first reducer 220, and the first driving wheel 230 is connected to the first driven wheel 240 through the first synchronous belt 250, and the first driving wheel 230 and the first driven wheel 240 respectively rotate the two ends of the first transmission frame 260 around their own axis, and the top of both sides of the first transmission frame 260 are integrally formed with a first guide rail 261 with the same length direction as the first transmission frame 260; and the specific structure of the conveying member 400 is as shown Figures 9-11 As shown, the conveying member 400 and the first transmission frame 260 have the same length direction, the conveying member 400 is fixedly connected to the first synchronous belt 250, and the conveying member 400 slides with the first guide rails 261 on both sides of the first transmission frame 260, and the side of the conveying member 400 adjacent to the tape insertion and cutting device is provided with a joint connected to the negative pressure hole 402, which facilitates the first negative pressure device to maintain a step with the negative pressure hole 402 through the pipeline. After the first negative pressure device is started, the negative pressure hole 402 can form a negative pressure that can adsorb the net bag body 100.

[0067] When the first motor 210 drives the first driving wheel 230 to rotate around its own axis through the first reducer 220, the first driving wheel 230 cooperates with the first driven wheel 240 to drive the first synchronous belt 250 to rotate, so that the conveying member 400 fixedly connected to the first synchronous belt 250 moves along the length direction of the first transmission frame 260. Under the guidance of the first guide rails 261 on both sides of the first transmission frame 260, the conveying member 400 moves smoothly along the first guide rails 261.

[0068] The specific structures of the first moving assembly 700 and the second moving assembly 800 are as follows: Figure 4-Figure 7As shown, the first moving assembly 700 includes three first lifting cylinders 701 equally spaced along the length direction of the first transmission frame 260. The first lifting cylinder 701 is arranged vertically upward, and its cylinder body is fixedly connected to the first frame body 301. The top of the piston rod is fixedly connected to the first lifting plate 702. The bottom of the first lifting plate 702 is fixedly connected to the suction cup 500 through the suction pipe 390. The top of the first lifting plate 702 is fixedly connected to the negative pressure pipe 380. The suction cup 500 is connected to the negative pressure pipe 380 through the suction pipe 390. The negative pressure pipe 380 is used to connect to the second negative pressure device. The suction cup 500 is located directly above the transmission surface of the first synchronous belt 250.

[0069] When the second negative pressure device is started, air is pumped into the suction cup 500 through the negative pressure pipe 380 and the suction pipe 390 in turn, so that negative pressure is formed in the suction cup 500, and the side of the net bag body 100 away from the conveying member 400 is adsorbed. Then, the first lifting cylinder 701 drives the first lifting plate 702 to move upward. The first lifting plate 702 drives the suction cup 500 to move upward through the suction pipe 390, thereby increasing the opening width of the net bag body 100 to facilitate the insertion of the end of the strip 200.

[0070] The second moving assembly 800 includes two second lifting cylinders 801 arranged on the first frame 301 and pointing downward. The cylinder bodies of the two second lifting cylinders 801 are fixed on the first frame 301, and the bottom of the piston rod is connected to the heat sealing member 600. The operation of the second lifting cylinders 801 drives the heat sealing member 600 to move up and down. When the heat sealing member 600 presses the mesh bag body 100 and the strip 200 onto the conveying member 400, the heat sealing forming of the mesh bag body 100 and the strip 200 can be achieved. After the heat sealing member 600 moves upward, it is convenient to collect the heat-sealed products.

[0071] In a preferred embodiment, the inserting and cutting device includes a mobile clamping assembly and a cutting assembly 900, the mobile clamping assembly includes a clamping assembly for clamping the end of the strip 200 and a third mobile assembly for driving the clamping assembly to move back and forth between a clamping position and a release position, the release position is located between the cutting assembly 900 and the processing position, the clamping position is located on the side of the cutting assembly 900 away from the processing position, and the cutting assembly 900 is used to cut the strip 200, such as Figure 3 shown.

[0072] After adopting the above structure, the third moving component drives the clamping component to move back and forth between the release position and the clamping position. When the clamping component moves to the clamping position, the clamping component clamps the strip 200, and then the third moving component drives the clamping component to move to the release position, and inserts the end of the strip 200 into the opening of the net bag body 100 on the adsorption surface 401 of the conveying member 400 at the processing position. The cutting component 900 cuts the strip 200, and then the processing device heat-seals the net bag body 100 and the strip 200 to form a product. The worker takes away the heat-sealed net bag, and then the third moving component moves the clamping component to clamp the external clamping strip 200, and the operation is cyclical.

[0073] The third moving component and the transmission device also belong to the synchronous belt module linear guide rail. The specific structure of the third moving component is as follows: Figure 7 and Figure 8 As shown, the third moving assembly is long and extends in the horizontal direction. The length direction of the third moving assembly is perpendicular to the length direction of the transmission device. Specifically, the third moving assembly includes a second long transmission frame 360. The second transmission frame 360 is fixedly connected to the second frame 302. A second synchronous belt 350 is rotatably provided on the second transmission frame 360. A second motor 310 and a second reducer 320 are provided on the side of one end of the second transmission frame 360 connected to the transmission device. The second motor 310 is fixed to the second transmission frame 360 through the second reducer 320. The second motor 310 is connected to the second driving wheel 330 through the second reducer 320, and the second driving wheel 330 is connected to the second driven wheel 340 through the second synchronous belt 350. The second driving wheel 330 and the second driven wheel 340 rotate around their own axis lines at the two ends of the second transmission frame 360 respectively. The top two sides of the second transmission frame 360 are integrally formed with second guide rails 361 with the same length direction as the second transmission frame 360. The second guide rails 361 are slidably connected to the sliding frame 370, and the sliding frame 370 is connected to the clamping assembly.

[0074] When the second motor 310 is started, the second drive wheel 330 can be driven to rotate through the second reducer 320. The second drive wheel 330 cooperates with the second driven wheel 340 to drive the second synchronous belt 350 to rotate, so that the sliding frame 370 fixedly connected to the second synchronous belt 350 moves. Under the guidance of the second guide rail 361, the sliding frame 370 drives the clamping assembly to move smoothly along the length direction of the second guide rail 361.

[0075] In a preferred embodiment, at least two adsorption areas are provided on the adsorption surface 401 along the moving direction of the conveyor 400, the negative pressure holes 402 are provided on the adsorption areas, and the number of cutting components 900, the number of suction cups 500 and the number of adsorption areas are equal and corresponding.

[0076] Specifically, such as Figure 9 and Figure 10 As shown, the suction surface 401 has four suction zones spaced evenly along the length of the first transport frame 260, each equipped with two negative pressure holes 402. This design increases the number of negative pressure holes 402, expanding the suction contact area and the number of suction holes on the mesh bag body 100, and enhancing the suction effect. Accordingly, four equally spaced suction cups 500 are fixed beneath the first lifting plate 702, each used to suction the four mesh bag bodies 100 facing away from the conveyor 400. Four cutting assemblies 900 are also provided, each used to cut the four strips 200 inserted into the openings of the four mesh bag bodies 100. This allows the device to heat-seal and form four mesh bag products in one go, significantly improving production efficiency. Of course, the number of suction zones on the suction surface 401 and the number of negative pressure holes 402 in each zone can be adjusted to improve production efficiency based on actual production needs and product dimensions.

[0077] In a preferred embodiment, the cutting assembly 900 includes a downward first pneumatic scissors 901 and an upward second pneumatic scissors 902. The shell of the first pneumatic scissors 901 and the shell of the second pneumatic scissors 902 are both fixed on the frame 300. The movable shaft of the first pneumatic scissors 901 is connected to the first upper pressure plate 110, and the movable shaft of the second pneumatic scissors 902 is connected to the first lower support plate 120. Before the first pneumatic scissors 901 and the second pneumatic scissors 902 cut the strip 200, the first upper pressure plate 110 and the first lower support plate 120 clamp the strip 200 and cooperate with the movable clamping assembly to tension the strip 200; the first upper pressure plate 110 and / or the first lower support plate 120 are connected to an elastic member 130 to increase the clamping force of the first upper pressure plate 110 and the first lower support plate 120 on the strip 200.

[0078] Specifically, such as Figure 13 、 Figure 14 、 Figure 16 and Figure 17As shown, the four cutting components 900 are two first pneumatic scissors 901 and two second pneumatic scissors 902. The first pneumatic scissors 901 are downward and fixed on the second frame 302, and the second pneumatic scissors 902 are upward fixed on the second frame 302. The movable axis of the first pneumatic scissors 901 is fixedly connected to the connecting plate 410 through the upper connecting frame 270. The first upper pressing plate 110 is long and extends in a length direction parallel to the first transmission frame 260. The two ends of the first upper pressing plate 110 are respectively arranged directly below the two ends of the connecting plate 410 through two elastic members 130. The elastic member 130 is a spring, and a directional rod 290 extending in the vertical direction is fixed above both ends of the first upper pressure plate 110. The directional rod 290 is located on the inner side of the elastic member 130. The bottom surface of the first upper pressure plate 110 is fixed with a first upper elastic pad 111, and the movable axis of the second pneumatic scissors 902 is fixedly connected to the first lower support plate 120 through the lower connecting frame 280. The top surface of the first lower support plate 120 is fixed with a first lower elastic pad 121. The length directions of the first upper pressure plate 110, the first upper elastic pad 111, the first lower support plate 120 and the first lower elastic pad 121 are parallel to each other.

[0079] After the four cutting components 900 adopt the above structure, the first pneumatic scissors 901 and the second pneumatic scissors 902 cooperate with each other to drive the first upper pressure plate 110 to move downward and the first lower support plate 120 to move upward. The first lower elastic pad 121 and the first upper elastic pad 111 can clamp the strip 200 to prevent the strip 200 from loosening. At the same time, due to the setting of the elastic part 130, the movable axes of the first pneumatic scissors 901 and the second pneumatic scissors 902 can continue to move, driving their respective blades to move upward and rotate at the same time, thereby realizing simultaneous cutting of the four strips 200 and improving cutting efficiency.

[0080] In a preferred embodiment, the clamping assembly includes a clamping frame 140 connected to the output end of the third moving assembly, and the clamping frame 140 is provided with a second upper pressure plate 150, a second lower support plate 160 and a distance adjustment assembly 170 for adjusting the second upper pressure plate 150 and the second lower support plate 160.

[0081] Specifically, such as Figure 13-15 、 Figure 18 and Figure 19As shown, the clamping frame 140 is generally U-shaped with the opening facing upward, and its bottom is fixedly connected to the sliding frame 370. The width of the U-shaped opening of the clamping frame 140 is greater than the width of the second frame body 302 and the length of the first upper pressure plate 110, the first upper elastic pad 111, the first lower support plate 120, and the first lower elastic pad 121, so that the third moving component can drive the clamping frame 140 to move to the clamping position through the four cutting components 900. There are two distance adjusting components 170, which are located on the inner walls on both sides of the clamping frame 140 respectively. The distance adjusting components 170 include two third lifting cylinders 171 arranged opposite each other. The cylinder barrels of the two third lifting cylinders 171 are fixed on the clamping frame 140. One of them is located directly above the end of the second upper pressure plate 150, and the bottom end of its piston rod is fixedly connected to the end of the second upper pressure plate 150. The other third lifting cylinder 171 is located directly below the end of the second lower support plate 160, and the top end of its piston rod is fixedly connected to the end of the second lower support plate 160. A second upper elastic pad 151 is fixed below the second upper pressure plate 150, and a second lower elastic pad 161 is fixed above the second lower support plate 160. The second upper elastic pad 151 and the second lower elastic pad 161 both extend in a length direction parallel to the first upper elastic pad 111.

[0082] After adopting the above structure, the distance between the second upper pressure plate 150 and the second lower support plate 160 is adjusted by operating the two third lifting cylinders 171 arranged opposite to each other. When the third moving assembly moves the clamping frame 140 to the clamping position, the second upper pressure plate 150 and the second lower support plate 160 are respectively located above and below the strip 200. At this time, the two third lifting cylinders 171 respectively drive the second upper pressure plate 150 to descend and the second lower support plate 160 to rise, so that the second upper elastic pad 151 and the second lower elastic pad 161 clamp the strip 200, and then the third moving assembly drives the clamping frame 140 to move, so that The clamping frame 140 is moved to the release position so that the end of the clamped strip 200 can extend into the opening of the mesh bag body 100, and then the four strips 200 are cut by two first pneumatic scissors 901 and two second pneumatic scissors 902. After the second moving component 800 drives the heat sealing part 600 to move down for heat sealing and forming, the two third lifting cylinders 171 respectively drive the second upper pressure plate 150 and the second lower support plate 160 to descend, making it convenient for workers to collect the heat-sealed products. At this time, the third moving component moves the clamping frame 140 to the clamping position to clamp the strip 200 through the clamping component.

[0083] In a preferred embodiment, the frame 300 is further provided with a feed hole 180, which is adapted to the cross section of the strip 200. The feed hole 180 is provided on the side of the clamping assembly away from the processing position. Figure 17As shown, there are four feed holes 180, which are located on the second frame 302. The four feed holes 180 are evenly spaced along the length direction of the first transmission frame 260. The length of the feed holes 180 is the same as the width of the strip 200, to prevent the direction and position of the strip 200 from shifting during the feeding process. In this way, the feed holes 180 are helpful to ensure the stable transmission and feeding of the strip 200. Not only that, after the feed holes 180 are set, the four cutting components 900 are located on the side of the feed holes 180 adjacent to the transmission device. After the four cutting components 900 cut the four strips 200, the remaining parts of the cutting still remain through the feed holes 180, which is convenient for the third moving component to drive the clamping component to move to the clamping position to clamp the part of the strip 200 passing through the feed holes 180.

[0084] In a preferred embodiment, a guide assembly 190 is further provided on the side of the feed hole 180 away from the processing position, and the guide assembly 190 is used to guide the strip 200 to pass through the inner side of the feed hole 180 in a direction perpendicular to the opening of the feed hole 180; the guide assembly 190 includes a third upper pressure plate 191 and a third lower support plate 192 arranged directly below the third upper pressure plate 191, the third upper pressure plate 191 and the third lower support plate 192 are clearance-fitted and loosely fit with the strip 200; one of the third upper pressure plate 191 and the third lower support plate 192 is a movable part, and the other is a fixed part, the fixed part is connected to a guide rod 193 extending in the vertical direction, the movable part is sleeved on the outside of the guide rod 193 and slidably fits with the guide rod 193, the guide rod 193 is threadedly connected to a screw sleeve 194, and the movable part is arranged between the fixed part and the screw sleeve 194.

[0085] Specifically, the third lower supporting plate 192 is fixed on the second frame 302 and extends in a length direction parallel to the first transmission frame 260. Guide rods 193 extending in the vertical direction are fixed above both ends of the third lower supporting plate 192. Both ends of the third upper pressing plate 191 are sleeved outside the two guide rods 193. Through the two guide rods 193, the third upper pressing plate 191 can slide in the vertical direction, that is, the third upper pressing plate 191 is a movable part and the third lower supporting plate 192 is a fixed part (of course, this device can also be selected as The third lower supporting plate 192 is designed as a movable part, and the third upper pressure plate 191 is fixedly connected to the second frame body 302), the screw sleeve 194 is a nut, which is threadedly matched with the guide rod 193, and a third upper elastic pad 1911 is fixed below the third upper pressure plate 191, and a third lower elastic pad 1921 is fixed above the third lower supporting plate 192. The length directions of the third upper pressure plate 191, the third lower supporting plate 192, the third upper elastic pad 1911 and the third lower elastic pad 1921 are parallel to each other.

[0086] After adopting the above structure, the screw sleeve 194 that is threadedly engaged with the guide rod 193 is used to limit the range of movement of the third upper pressure plate 191, so that the third upper pressure plate 191 and the third lower support plate 192 maintain a clearance fit. Before passing through the feed hole 180, the strip 200 is clamped by the third upper elastic pad 1911 and the third lower elastic pad 1921 to prevent the strip 200 from deviating, ensuring that the strip 200 is fed in a direction perpendicular to the opening of the feed hole 180, so that the strip 200 passes through the feed hole 180, thereby realizing stable feeding of the strip 200.

[0087] It should be noted that the first upper elastic pad 111, the first lower elastic pad 121, the second upper elastic pad 151, the second lower elastic pad 161, the third upper elastic pad 1911 and the third lower elastic pad 1921 submitted in the present invention are all made of elastic materials, including but not limited to sponge, rubber, silicone, and latex.

[0088] In a preferred embodiment, two conveying members 400, two tape cutting devices and two processing devices are provided, and the tape cutting devices correspond to the processing devices one by one. The conveying members 400 are spaced apart along their own moving direction. The two conveying members 400 are respectively the first conveying member 400 and the second conveying member 400. The transmission device drives the first conveying member 400 and the second conveying member 400 to move synchronously. When the first conveying member 400 moves to its corresponding processing position, the second conveying member 400 moves to its corresponding feeding position. When the first conveying member 400 moves to its corresponding feeding position, the second conveying member 400 moves to its corresponding processing position; the feeding position of the first conveying member 400 coincides with the feeding position of the second conveying member 400, as shown in FIG. Figure 1 and Figure 2 shown.

[0089] After adopting the above structure, the mesh bag forming machine of the present invention has two conveying members 400, namely the first conveying member 400 and the second conveying member 400. When the first conveying member 400 is located at the feeding position, the second conveying member 400 is located at the processing position. At this time, the worker can place the mesh bag body 100 on the first conveying member 400, and at the same time, the processing device and the bag insertion and cutting device cooperate with each other. First, the opening width of the mesh bag body 100 on the second conveying member 400 is increased, and then the strip 200 is inserted, the strip 200 is cut, and the strip 200 is heat-sealed; when the first conveying member 400 is located at the processing position, the second conveying member 400 is located at the feeding position, and the worker is responsible for providing the mesh bag body 100 to the second conveying member 400. At the same time, the processing device and the bag insertion and cutting device cooperate with each other to insert the strip 200 into the mesh bag body 100 on the first conveying member 400 for heat-sealing molding, thereby greatly improving production efficiency. Furthermore, the feeding position of the first conveying member 400 coincides with the feeding position of the second conveying member 400 , thereby facilitating feeding of the two conveying members 400 at the same position, which is beneficial to improving production efficiency. In addition, it makes the equipment structure more compact and saves production operation space.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
