Description

A fully automatic plastic bag sealing and cutting machine Technical Field

[0001] The embodiments disclosed herein relate to the field of plastic bag sealing and cutting technology, and more specifically, to a fully automatic plastic bag sealing and cutting machine. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, and nylon). They are essential items in daily life and are often used to store other items. They are widely used due to their low cost, light weight, large capacity, and ease of storage. Plastic bags are generally made by cutting continuous tubular plastic film to a fixed length and then heat-sealing one end. The machine that cuts the plastic film to a fixed length and heat-seals it is called a plastic bag sealing and cutting machine.

[0003] While existing plastic bag sealing and cutting machines can automatically seal and cut plastic bags, they can only seal and cut one plastic bag at a time, resulting in low sealing and cutting efficiency. This makes them unsuitable for large-scale production needs. Furthermore, during automatic sealing and cutting, the heat sealing and cutting device cannot buffer the heat sealing blade while cutting the plastic bag. The blade blade collides with the worktable for a long time, which can easily damage the blade blade and increase the cost of plastic bag production and processing.

[0004] Therefore, it is necessary to provide a fully automatic plastic bag sealing and cutting machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a fully automatic plastic bag sealing and cutting machine, which solves the technical problem in the prior art that the heat sealing knife cannot be buffered when cutting plastic bags.

[0009] For example, in at least one embodiment of the present disclosure, a fully automatic plastic bag sealing and cutting machine is provided, which further includes: an inner connecting hole on the outer side of the connecting block, an outer connecting hole that mates with the inner connecting hole on the inner side of the connecting groove, and the inner connecting hole and the outer connecting hole being connected by bolts.

[0010] For example, in at least one embodiment of the present disclosure, a fully automatic plastic bag sealing and cutting machine is provided, which further includes: a first guide block and a second guide block are respectively provided on both sides of the lifting plate; the first guide block and the second guide block are slidably connected to a first guide groove and a second guide groove; the first guide groove and the second guide groove are provided on the sides of the first guide plate and the second guide plate; and the bottom of the first guide plate and the second guide plate are connected to both ends of the top of the machine.

[0011] For example, in at least one embodiment of this disclosure, a fully automatic plastic bag sealing and cutting machine is provided, which further includes: the number of lifting cylinders is multiple, and the lifting cylinders are linearly and equidistantly distributed at the bottom of the moving plate.

[0012] For example, in at least one embodiment of the present disclosure, a fully automatic plastic bag sealing and cutting machine is provided, which further includes: the material transfer mechanism includes multiple material transfer plates, multiple vacuum nozzles are installed at the bottom of the material transfer plates, the air inlet of the vacuum nozzles is connected to a vacuum pump through an air pipe, the vacuum pump is installed on the top of the material transfer plates, and the top of the material transfer plates is connected to a displacement mechanism that can move the material transfer plates in multiple directions.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] In this disclosure, by setting multiple feeding shafts, multiple tubular plastic films can be sleeved on the feeding shafts during sealing and cutting operations. Through the action of the transmission component, the plastic films are driven to move forward and move to the top of the cutting table. Driven by the lifting cylinder, the lifting plate is driven to move downward, which in turn drives the cutter and heat sealer to move downward, realizing the cutting and heat sealing of multiple plastic films, improving the sealing and cutting efficiency. During the cutting process, the cutter enters the cutting groove, which buffers the bottom of the cutter and prevents the cutting edge from colliding with the worktable for a long time during cutting, which can easily cause damage to the cutting edge and increase the cost of plastic bag production and processing.

[0018] In this disclosure, by setting a vacuum nozzle, the vacuum pump can be turned on and off to achieve the suction and delivery of air. When moving the plastic bag, atmospheric pressure can be used to adsorb the plastic bag onto the vacuum nozzle to fix the plastic bag, which is convenient to move the plastic bag through a subsequent displacement mechanism.

[0019] In this disclosure, by setting a protective plate that is threadedly connected to the feeding shaft, after multiple cylindrical plastic films are sleeved on the feeding shaft, the protective plate can be rotated to protect one side of the cylindrical plastic film, preventing the cylindrical plastic film from falling off the feeding shaft during rotation and affecting subsequent use.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] As shown in Figures 1-5, a fully automatic plastic bag sealing and cutting machine according to an embodiment of this disclosure is illustrated, comprising: a machine base 1, a plurality of feeding plates 2 mounted on the top of the machine base 1, feeding shafts 3 mounted on the sides of the feeding plates 2, a transmission assembly 6 for transmitting plastic film on one side of the feeding shaft 3, the transmission assembly 6 being driven by a transmission motor 7, a plurality of cutting tables 25 mounted on the top of the machine base 1 on one side of the transmission assembly 6, a cutting groove 26 for moving a cutter 34 being provided on the top of the cutting table 25, a cutter 34 being positioned above the cutting groove 26, the top of the cutter 34 being movably connected to the bottom of a lifting plate 9, the upper end of a heat sealing machine 28 being mounted on the bottom of the lifting plate 9 on one side of the cutter 34, and the cutting table 25... The top is provided with an installation groove 27, and the lower end of the heat sealing machine 28 is installed inside the installation groove 27. The top of the lifting plate 9 is connected to the telescopic end of the lifting cylinder 8. The fixed plate of the lifting cylinder 8 is connected to the bottom end of the horizontal plate of the L-shaped support plate 10. The side of the vertical end of the support plate 10 is connected to the side of the machine base 1. A feeding cylinder 16 is installed on the side of the machine base 1 on one side of the cutting table 25. Multiple push rods 17 are installed on the periphery of the feeding cylinder 16. One end of the feeding cylinder 16 passes through the side of the machine base 1 and is connected to the drive end of the feeding motor 18. A receiving table 15 is provided on one side of the cutting table 25. A material transfer mechanism 11 that can move plastic bags is provided above the receiving table 15. The material transfer mechanism 11 is connected to the machine base 1 through a connecting frame 12.

[0034] It should be noted that by setting multiple feeding shafts 3, multiple cylindrical plastic films can be sleeved on the feeding shafts 3 during the sealing and cutting operation. Through the action of the transmission component 6, the plastic films are driven forward and moved above the cutting table 25. Driven by the lifting cylinder 8, the lifting plate 9 is driven downward, which in turn drives the cutter 34 and the heat sealer 28 downward, realizing the cutting and heat sealing of multiple plastic films, improving the sealing and cutting efficiency. During the cutting process, the cutter 34 enters the cutting groove 26, which buffers the bottom of the cutter 34 and prevents the blade of the cutter 34 from colliding with the worktable for a long time during cutting, which could easily cause damage to the blade and increase the cost of plastic bag production and processing.

[0035] After sealing and cutting, the feeding motor 18 drives the feeding cylinder 16 to rotate, moving the cut plastic bags to the receiving platform 15. Then, the material transfer mechanism 11 moves the plastic bags on the receiving platform 15 to the receiving area, completing the plastic bag receiving operation.

[0036] In some examples, referring to Figure 2, the transmission assembly 6 includes a plurality of first transmission cylinders 13 and a plurality of second transmission cylinders 14. The two ends of the first transmission cylinders 13 are rotatably connected to the lower ends of the two inner sides of the machine base 1. The number of first transmission cylinders 13 and second transmission cylinders 14 is the same and they correspond one-to-one. The corresponding second transmission cylinder 14 is located directly above the first transmission cylinder 13. The two ends of the second transmission cylinder 14 are rotatably connected to the upper ends of the two inner sides of the machine base 1. The first transmission cylinders 13 and second transmission cylinders 14 are connected to the drive end of the transmission motor 7 through a transmission mechanism.

[0037] It should be noted that by setting the first transmission cylinder 13 and the second transmission cylinder 14, the plastic film can be positioned between the first transmission cylinder 13 and the second transmission cylinder 14 during transmission. The stability of the plastic film during transmission is improved by using the clamping of the first transmission cylinder 13 and the second transmission cylinder 14.

[0038] In some examples, referring to Figure 5, the cutter 34 includes a cutter body 35, and a connecting block 36 is mounted on the top of the cutter body 35. The connecting block 36 is movably connected to a connecting groove 38, which is located at the bottom of the lifting plate 9.

[0039] In some examples, referring to Figure 5, the outer side of the connecting block 36 is provided with an inner connecting hole 37, and the inner side of the connecting groove 38 is provided with an outer connecting hole 39 that mates with the inner connecting hole 37. The inner connecting hole 37 and the outer connecting hole 39 are connected by bolts.

[0040] It should be noted that by setting the cutter 34 to be movably connected to the connecting slot 38, when the cutter 34 is damaged during use, the damaged cutter 34 can be quickly removed from the moving plate 23 and a new cutter 34 can be quickly installed on the lifting plate 9, thereby improving the efficiency of cutter 34 replacement.

[0041] In some examples, referring to Figure 3, the lifting plate 9 is provided with a first guide block 29 and a second guide block on its two sides respectively. The first guide block 29 and the second guide block are slidably connected to the first guide groove 30 and the second guide groove 33. The first guide groove 30 and the second guide groove 33 are provided on the sides of the first guide plate 31 and the second guide plate 32. The bottom of the first guide plate 31 and the second guide plate 32 are connected to the two ends of the top of the machine base 1.

[0042] It should be noted that by setting the first guide block 29 and the second guide block, the stability of the lifting plate 9 when moving up and down can be improved by limiting the first guide groove 30 and the second guide groove 33.

[0043] In some examples, referring to Figure 1, there are multiple lifting cylinders 8, which are linearly and equidistantly distributed at the bottom of the moving plate 23.

[0044] It should be noted that by setting multiple lifting cylinders 8, the top of the lifting plate 9 is subjected to uniform force, which improves the stability of the lifting plate 9 when it moves up and down.

[0045] In some examples, referring to Figure 2, the material transfer mechanism 11 includes a plurality of material transfer plates 19, a plurality of vacuum nozzles 20 are mounted on the bottom of the material transfer plates 19, the air inlet end of the vacuum nozzles 20 is connected to a vacuum pump 21 through an air pipe, the vacuum pump 21 is mounted on the top of the material transfer plates 19, and the top of the material transfer plates 19 is connected to a displacement mechanism that can move the material transfer plates 19 in multiple directions.

[0046] In some examples, referring to Figure 2, the number of vacuum nozzles 20 is 6, and the vacuum nozzles 20 are arranged in two rows at the bottom of the transfer plate 19.

[0047] It should be noted that by setting up the vacuum nozzle 20, the vacuum pump 21 can be opened and closed to achieve the suction and delivery of air through the vacuum nozzle 20. When moving the plastic bag, atmospheric pressure can be used to adsorb the plastic bag onto the vacuum nozzle 20, thereby fixing the plastic bag and facilitating its movement through the subsequent displacement mechanism.

[0048] In some examples, referring to Figure 2, the displacement mechanism includes a transverse slide rail 24, the side of which is connected to the connecting frame 12. The transverse slide rail 24 is connected to the top of the moving plate 23 via a slider, and the bottom of the moving plate 23 is connected to the top of the transferring plate 19 via a transferring cylinder 22.

[0049] It should be noted that the horizontal slide rail 24 can drive the moving plate 23 to move left and right, and the material transfer cylinder 22 can realize the up and down movement of the material transfer plate 19. In cooperation with the moving plate 23, the material transfer plate 19 can finally move up, down and left and right.

[0050] In some examples, referring to Figure 1, the outer surface of the feeding shaft 3 is provided with an external thread 4, and the outer surface of the external thread 4 is connected to a protective plate 5 by a thread.

[0051] It should be noted that by setting a protective plate 5 that is threadedly connected to the feeding shaft 3, after multiple cylindrical plastic films are sleeved on the feeding shaft 3, the protective plate 5 can be rotated to protect one side of the cylindrical plastic film, preventing the cylindrical plastic film from falling off the feeding shaft 3 during rotation and affecting subsequent use.

[0052] The working principle of the fully automatic plastic bag sealing and cutting machine provided by this utility model is as follows:

[0053] By setting multiple feeding shafts 3, multiple cylindrical plastic films can be sleeved on the feeding shafts 3 during sealing and cutting operations. Through the action of the transmission component 6, the plastic films are driven forward and moved above the cutting table 25. Driven by the lifting cylinder 8, the lifting plate 9 is driven downward, which in turn drives the cutter 34 and the heat sealer 28 downward, realizing the cutting and heat sealing of multiple plastic films, improving the sealing and cutting efficiency. During the cutting process, the cutter 34 enters the cutting groove 26, which buffers the bottom of the cutter 34 and prevents the blade of the cutter 34 from colliding with the worktable for a long time during cutting, which can easily cause damage to the blade and increase the cost of plastic bag production and processing.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
