Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a packaging device for a printing bag making machine. Background Art

[0002] Printing bag making machine is a machine for making various plastic packaging bags or other material packaging bags. Its processing range is various sizes, thicknesses and specifications of plastic or other materials packaging bags. Generally speaking, plastic packaging bags are the main products.

[0003] However, in the prior art, some packaging devices of bag making machines generate bubbles due to poor exhaust when sealing plastic bags, which in turn affects the quality of the product and further affects the stability and reliability of the packaged product; and oversized plastic bags can only be heat-sealed in sections, and multiple heat-sealing operations cannot ensure that the sealing joints are perfectly heat-sealed without gaps, and cannot meet the sealing requirements.

[0004] In the prior art, a Chinese patent with publication number CN 219749076U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a packaging device for a printing bag making machine, including a frame plate, a convex groove is opened on one side of the frame plate, a slide plate is movably embedded in the convex groove, a hydraulic rod is installed on the surface of the slide plate, and a heating device is provided at the bottom of the hydraulic rod. The utility model places the interface of the plastic bag to be packaged on the surface of the force-bearing plate, starts the hydraulic rod, and the hydraulic rod will drive the heating device to apply pressure downward, starts the heating tube, and heats the heating tube. The upper pressure plate is made of high-temperature resistant material, and the upper pressure plate fixes the heating tube. The insulation strip is made of an insulation board, which insulates the heating tube to prevent scalding of the staff. The heat conductive sheet is made of copper, which conducts heat to the heating tube. The arc of the force-bearing plate is semicircular. As the air in the center of the seal of the plastic bag is pressed, it will be squeezed to both sides to achieve the effect of expelling excess air. However, when sealing the plastic packaging bag, dust will fall in, which will lead to loose sealing. Moreover, when the heating tube is working, it is easy to cause burns to the skin of the staff, thus causing problems caused by low efficiency. Summary of the invention

[0005] The purpose of the utility model is to provide a packaging device for a printing bag-making machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A packaging device for a printing bag making machine includes a shell, a motor is fixedly connected to one side of the shell, a blocking plate is fixedly connected to the inside of the shell, a sliding door is slidably connected to one side of the shell, a handle is fixedly connected to the sliding door, a rotating shaft and a screw rod are rotatably connected to the inside of the shell, a first bevel gear is fixedly connected to the output end of the motor, a plurality of first bevel gears are fixedly connected to the screw rod and the rotating shaft, the first bevel gears are meshed with each other, the rotating shaft blocking plate is rotatably connected, a support shaft is rotatably connected to the bottom of the shell, a plurality of nozzles are evenly arranged on the side of the blocking plate close to the sliding door, a piston component for supplying air to the nozzle is connected to one side of the blocking plate, and a packaging component for packaging bags is connected to the side of the blocking plate close to the sliding door.

[0008] When the plastic packaging bag needs to be packaged, the plastic packaging bag is fixed and the motor is turned on. The operation of the motor will drive the first bevel gear meshing with it to rotate. Because the first bevel gears are meshing with each other, the rotation of the motor can transmit power to the screw rod through the first bevel gear and the rotating shaft, thereby driving the screw rod to rotate. The rotation of the screw rod will drive the packaging component to work, thereby achieving the purpose of packaging the plastic packaging bag. At the same time, when the motor drives the rotating shaft to rotate, the rotating shaft will transmit power to the piston component, thereby driving the piston component to work and transmit air to the nozzle, so that the nozzle can blow away the dust on the surface of the plastic packaging bag before packaging, and the flowing gas can be used to cool the sealed part of the plastic packaging bag after packaging. This can not only greatly improve work efficiency, but also reduce the occurrence of defective products.

[0009] A further improvement of the technical solution of the utility model is that: the packaging component includes a base plate, the base plate is slidably connected to the screw rod, the base plate is connected to the support shaft, an extrusion plate is arranged above the base plate, the extrusion plate is threadedly connected to the screw rod, the extrusion plate is slidably connected to the support shaft, a heating element is fixedly connected to the lower side of the extrusion plate, a protective shell is slidably connected to the outer side of the heating element, a spring is fixedly connected to one side of the protective shell, the other end of the spring is fixedly connected to the extrusion plate, the springs are symmetrically arranged, a pressing piece is rotatably connected to the base plate, and the pressing piece and the base plate are connected by a torsion spring.

[0010] The above technical solution is adopted. In this solution, when it is necessary to fix the plastic packaging bag, the pressing piece is lifted, the plastic packaging bag is placed, and then the pressing piece is lowered to fix it. Then, when the motor transmits power to the screw rod through the first bevel gear and the rotating shaft, the rotation of the screw rod will drive the extrusion plate to move downward. When the protective cover conflicts with the bottom plate, the extrusion plate continues to move downward, and the spring is compressed. When the extrusion plate moves to the bottom so that the heating element seals the plastic packaging bag, the motor reverses and drives the extrusion plate to move in the opposite direction until it returns to its original position. The provision of a protective cover can effectively prevent the heating element from causing harm to the staff during operation, and can also prevent debris from sticking to affect the working efficiency of the device.

[0011] A further improvement of the technical solution of the utility model is that: the piston component includes a cylinder body, the cylinder body is fixedly connected to the shell, the two ends of the cylinder body are respectively fixedly connected with the intake pipe and the delivery pipe, the intake pipe and the delivery pipe are both fixedly connected with a one-way valve, the other end of the delivery pipe is connected to the nozzle, an axis body is rotatably connected inside the shell, a disc is fixedly connected at one end of the axis body, pulleys are respectively fixedly connected on the axis body and the rotating shaft, the pulleys are connected by belt drive, a piston plate is slidably connected inside the cylinder body, and the piston plate and the disc are hinged by a connecting rod.

[0012] The above-mentioned technical solution is adopted. In this solution, when the motor drives the rotating shaft to rotate through the first bevel gear, the rotating shaft will transmit power to the shaft body through the pulley and belt fixedly connected thereto. The rotation of the shaft body will drive the disc to rotate. Because the connecting rod is hinged to the disc and the piston plate, the rotation of the disc will drive the piston plate to reciprocate in the cylinder body through the connecting rod, thereby achieving the function of delivering air to the nozzle to clean the plastic packaging bag before packaging and to cool the plastic packaging bag after packaging.

[0013] A further improvement of the technical solution of the utility model is that: a rotating shaft is rotatably connected to the shell, a knob is fixedly connected to one end of the rotating shaft, a second bevel tooth is fixedly connected to the end of the rotating shaft away from the knob, a second bevel tooth is fixedly connected to the support shaft, the second bevel teeth are meshed with each other, a threaded groove is opened on the upper part of the support shaft, and the bottom plate is threadedly connected to the threaded part of the support shaft.

[0014] The above technical solution is adopted. In this solution, when the position of the base plate needs to be adjusted, the rotating knob drives the rotating shaft to rotate. The rotation of the rotating shaft drives the supporting shaft to rotate through the mutual engagement of the second bevel teeth, thereby driving the base plate threadedly connected thereto to adjust the height direction. Through such a setting, the position of the base plate can be effectively adjusted to prevent the work efficiency from being reduced due to insufficient reserved space near the base plate.

[0015] A further improvement of the technical solution of the utility model is that the height of the protective sleeve is smaller than the height of the heating element.

[0016] The above technical solution is adopted, in which the height of the protective cover is set to be smaller than the height of the heating element in order to prevent the protective cover from affecting the packaging work of the heating element during operation due to its too high height.

[0017] A further improvement of the technical solution of the utility model is that a filter screen is fixedly connected and arranged in the air intake pipe.

[0018] The above technical solution is adopted. In this solution, because the air generally contains some tiny particles and dust, the dust and particles may block the nozzle during the packaging work, making the nozzle unable to work, which not only reduces the work efficiency but also may damage the nozzle. By setting a filter, the dust and particles can be effectively isolated from the outside, which effectively improves the working efficiency of the device.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a packaging device for a printing bag making machine. When the position of the bottom plate needs to be adjusted, the rotating knob drives the rotating shaft to rotate. The rotation of the rotating shaft drives the supporting shaft to rotate through the mutual engagement of the second bevel teeth, thereby driving the bottom plate threadedly connected thereto to adjust the height direction. Through such an arrangement, the position of the bottom plate can be effectively adjusted to prevent the work efficiency from being reduced due to insufficient reserved space near the bottom plate.

[0021] 2. The utility model provides a packaging device for a printing bag-making machine. The height of the protective cover is set to be smaller than the height of the heating element in order to prevent the protective cover from affecting the packaging work of the heating element due to its too high height during operation.

[0022] 3. The utility model provides a packaging device for a printing bag making machine. Because the air generally contains some tiny particles and dust, the dust and particles may block the nozzle during the packaging work, making the nozzle unable to work, which not only reduces the work efficiency but also may damage the nozzle. By setting a filter, the dust and particles can be effectively isolated from the outside, which effectively improves the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the embodiments:

[0031] Example 1

[0032] like Figure 4 As shown, the utility model provides a packaging device for a printing bag making machine, including a shell 1, a motor 2 is fixedly connected to one side of the shell 1, a blocking plate 9 is fixedly connected inside the shell 1, a sliding door 7 is slidably connected to one side of the shell 1, a handle 8 is fixedly connected to the sliding door 7, a rotating shaft 3 and a screw rod 4 are rotatably connected inside the shell 1, a first bevel gear 5 is fixedly connected to the output end of the motor 2, a plurality of first bevel gears 5 are fixedly connected to the screw rod 4 and the rotating shaft 3, the first bevel gears 5 are meshed with each other, the rotating shaft 3 and the blocking plate 9 are rotatably connected, a support shaft 10 is rotatably connected to the bottom of the shell 1, a plurality of nozzles 11 are evenly arranged on the side of the blocking plate 9 close to the sliding door 7, a piston component for supplying air to the nozzles 11 is connected to one side of the blocking plate 9, and a packaging component for packaging bags is connected to the side of the blocking plate 9 close to the sliding door 7.

[0033] In this embodiment, when the plastic packaging bag needs to be packaged, the plastic packaging bag is fixed and the motor 2 is turned on. The operation of the motor 2 will drive the first bevel gear 5 meshing with it to rotate. Because the first bevel gears 5 are meshed with each other, the rotation of the motor 2 can transmit power to the screw rod 4 through the first bevel gear 5 and the rotating shaft 3, thereby driving the screw rod 4 to rotate. The rotation of the screw rod 4 will drive the packaging component to work, thereby achieving the purpose of packaging the plastic packaging bag. At the same time, when the motor 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 will transmit power to the piston component, thereby driving the piston component to work and transmit air to the nozzle 11, so that the nozzle 11 can blow away the dust on the surface of the plastic packaging bag before packaging, and the flowing gas can be used to cool the packaged part of the plastic packaging bag after packaging. This can not only greatly improve work efficiency, but also reduce the occurrence of defective products.

[0034] like Figure 2As shown, in the present embodiment, preferably, the packaging component includes a base plate 12, the base plate 12 is slidably connected to the screw rod 4, the base plate 12 is connected to the support shaft 10, an extrusion plate 13 is arranged above the base plate 12, the extrusion plate 13 is threadedly connected to the screw rod 4, the extrusion plate 13 is slidably connected to the support shaft 10, a heating element 14 is fixedly connected to the bottom of the extrusion plate 13, a protective shell 15 is slidably connected to the outer side of the heating element 14, a spring 16 is fixedly connected to one side of the protective shell 15, the other end of the spring 16 is fixedly connected to the extrusion plate 13, the spring 16 is symmetrically arranged, a pressing piece 17 is rotatably connected to the base plate 12, and the pressing piece 17 is connected to the base plate 12 by a torsion spring.

[0035] When the plastic packaging bag needs to be fixed, the pressing piece 17 is lifted, the plastic packaging bag is placed, and then the pressing piece 17 is lowered to fix it. Then, the motor 2 transmits power to the screw rod 4 through the first bevel gear 5 and the rotating shaft 3. At this time, the rotation of the screw rod 4 will drive the extrusion plate 13 to move downward. When the protective cover conflicts with the bottom plate 12, the extrusion plate 13 continues to move downward, and the spring 16 is compressed. When the extrusion plate 13 moves to the bottom so that the heating element 14 seals the plastic packaging bag, the motor 2 reverses and drives the extrusion plate 13 to move in the opposite direction until it returns to its original position. The provision of a protective cover can effectively prevent the heating element 14 from causing harm to the staff during operation, and can also prevent debris from adhering to and affecting the working efficiency of the device.

[0036] like Figure 3 As shown, preferably, the piston component includes a cylinder body 18, the cylinder body 18 is fixedly connected to the shell body 1, and the two ends of the cylinder body 18 are respectively fixedly connected with an intake pipe 19 and a delivery pipe 20, and the intake pipe 19 and the delivery pipe 20 are both fixedly connected with a one-way valve, and the other end of the delivery pipe 20 is connected to the nozzle 11. A shaft body 23 is rotatably connected inside the shell body 1, and a disc 25 is fixedly connected at one end of the shaft body 23. Pulleys 21 are respectively fixedly connected to the shaft body 23 and the rotating shaft 3, and the pulleys 21 are connected by a belt 22 for transmission. A piston plate 24 is slidably connected inside the cylinder body 18, and the piston plate 24 and the disc 25 are hinged by a connecting rod 26.

[0037] When the motor 2 drives the rotating shaft 3 to rotate through the first bevel gear 5, the rotating shaft 3 will transmit power to the shaft body 23 through the pulley 21 and the belt 22 fixedly connected thereto. The rotation of the shaft body 23 will drive the disc 25 to rotate. Because the connecting rod 26 is hinged to the disc 25 and the piston plate 24, the rotation of the disc 25 will drive the piston plate 24 to reciprocate in the cylinder body 18 through the connecting rod 26, thereby achieving the purpose of delivering air to the nozzle 11 to clean the plastic packaging bag before packaging and to cool the plastic packaging bag after packaging.

[0038] Example 2

[0039] like Figure 1 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a rotating shaft 27 is rotatably connected to the shell 1, a knob 28 is fixedly connected to one end of the rotating shaft 27, a second bevel gear 6 is fixedly connected to the end of the rotating shaft 27 away from the knob 28, a second bevel gear 6 is fixedly connected to the support shaft 10, the second bevel gears 6 are meshed with each other, a threaded groove 29 is opened on the upper part of the support shaft 10, and the bottom plate 12 is threadedly connected to the threaded part of the support shaft 10.

[0040] In this embodiment, when the position of the base plate 12 needs to be adjusted, the rotating knob 28 drives the rotating shaft 27 to rotate. The rotation of the rotating shaft 27 drives the support shaft 10 to rotate through the mutual engagement of the second bevel teeth 6, thereby driving the base plate 12 threadedly connected thereto to adjust the height direction. Through such a setting, the position of the base plate 12 can be effectively adjusted to prevent the work efficiency from being reduced due to insufficient reserved space near the base plate 12.

[0041] Example 3

[0042] like Figure 4 As shown, based on Example 2, the utility model provides a technical solution: preferably, the height of the protective sleeve is smaller than the height of the heating element 14.

[0043] In this embodiment, the height of the protective cover is set to be smaller than the height of the heating element 14 in order to prevent the protective cover from affecting the packaging work of the heating element 14 due to its too high height during operation.

[0044] Example 4

[0045] like Figure 4 As shown, based on Example 3, the utility model provides a technical solution: preferably, a filter screen 30 is fixedly connected and provided in the air intake duct 19 .

[0046] In this embodiment, because the air generally contains some tiny particles and dust, the dust and particles may block the nozzle 11 during the packaging work, making the nozzle 11 unable to work, which not only reduces the working efficiency but also may damage the nozzle 11. By setting the filter 30, the dust and particles can be effectively isolated from the outside, which effectively improves the working efficiency of the device.

[0047] The working principle of the packaging device for the printing bag making machine will be described in detail below.

[0048] like Figure 1-5As shown, when the plastic packaging bag needs to be packaged, the plastic packaging bag is fixed and the motor 2 is turned on. The operation of the motor 2 will drive the first bevel gear 5 meshing with it to rotate. Because the first bevel gears 5 are meshed with each other, the rotation of the motor 2 can transmit power to the screw rod 4 through the first bevel gear 5 and the rotating shaft 3, thereby driving the screw rod 4 to rotate. The rotation of the screw rod 4 will drive the packaging component to work, thereby achieving the purpose of packaging the plastic packaging bag. At the same time, when the motor 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 will transmit power to the piston component, thereby driving the piston component to work and transmit air to the nozzle 11, so that the nozzle 11 can blow away the dust on the surface of the plastic packaging bag before packaging, and the flowing gas can be used to cool the sealed part of the plastic packaging bag after packaging. This can not only greatly improve the work efficiency, but also reduce the occurrence of defective products. When the plastic packaging bag needs to be fixed, the pressing piece 17 is lifted, the plastic packaging bag is placed, and then the pressing piece 17 is lowered to fix it. Then, when the motor 2 transmits power to the screw 4 through the first bevel gear 5 and the rotating shaft 3, the screw 4 rotates to drive the extrusion plate 13 to move downward. When the protective cover contacts the bottom plate 12, the extrusion plate 13 continues to move downward, and the spring 16 is compressed. When the extrusion plate 13 moves to the bottom so that the heating element 14 seals the plastic packaging bag, the motor 2 reverses and drives the extrusion plate 13 to move in the opposite direction until it returns to its original position. The provision of a protective cover can effectively prevent the heating element 14 from causing harm to the staff during operation, and can also prevent debris from sticking to affect the working efficiency of the device. The height of the protective cover is set to be less than the height of the heating element 14 in order to prevent the protective cover from affecting the sealing work of the heating element 14 during operation due to its too high height. When the motor 2 drives the rotating shaft 3 to rotate through the first bevel gear 5, the rotating shaft 3 will transmit power to the shaft body 23 through the pulley 21 and the belt 22 fixedly connected thereto, and the rotation of the shaft body 23 will drive the disc 25 to rotate. Because the connecting rod 26 is hinged with the disc 25 and the piston plate 24, the rotation of the disc 25 will drive the piston plate 24 to reciprocate in the cylinder body 18 through the connecting rod 26, thereby achieving the function of delivering air to the nozzle 11 to clean the plastic packaging bag before packaging and cooling the plastic packaging bag after packaging. When the position of the bottom plate 12 needs to be adjusted, the rotating knob 28 drives the rotating shaft 27 to rotate, and the rotation of the rotating shaft 27 drives the support shaft 10 to rotate through the mutual engagement of the second bevel gear 6, thereby driving the bottom plate 12 threaded thereto to adjust the height direction. By such a setting, the position of the bottom plate 12 can be effectively adjusted to prevent the work efficiency from being reduced due to insufficient reserved space near the bottom plate 12.Because the air generally contains some tiny particles and dust, the dust and particles may block the nozzle 11 during the packaging work, making the nozzle 11 unable to work, which not only reduces the working efficiency but also may damage the nozzle 11. By setting the filter 30, the dust and particles can be effectively isolated from the outside, which effectively improves the working efficiency of the device.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
