This, combined with the cutting blade and cutting plate, enables quantitative cutting of the plastic plate, ensuring consistent cutting length during continuous cutting. As the mounting plate moves downwards, the limiting rod, spring, concave plate, and pressure plate effectively fix the plastic plate, ensuring stability during cutting. Rotating the threaded rod, in conjunction with the threaded block, slider, and fixing rod, moves the overlapping plate left and right, adjusting the horizontal distance between the cutting blade and the L-shaped baffle. This allows the device to adjust the quantitative cutting length of the plastic plate according to cutting requirements, increasing its flexibility during use. Attached Figure Description

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figure 1-7 As shown, a plastic packaging product manufacturing and cutting device with a conveying structure includes a base plate 1. A concave frame 4 is fixedly connected to the upper end of the base plate 1. Two electric hydraulic rods 12 are fixedly connected to the upper side inside the concave frame 4. The lower ends of the two electric hydraulic rods 12 are fixedly connected to a mounting plate 9. A cutting blade 8 is provided at the lower end of the mounting plate 9.

Through the cooperation between the conveying component 2 and the conveying component 3, the plastic sheet can be conveyed during the manufacturing process of the plastic packaging product. The plastic sheet can be conveyed to the top of the quantitative cutting component 5. By activating the two electric hydraulic rods 12, the mounting plate 9 is moved downwards, and with the cooperation of the cutting blade 8 and the quantitative cutting component 5, the plastic sheet can be quantitatively cut. The quantitative cutting component 5 can be appropriately adjusted according to the required cutting length of the plastic sheet, thereby increasing the flexibility of the cutting process.

[0030] Furthermore, the front and rear ends of the mounting plate 9 are movably connected to the concave frame 4, which has grooves inside both ends. The upper end of the concave frame 4 is fixedly connected to two limiting rods 10. The two limiting rods 10 are movably connected to two concave plates 7, which have limiting holes inside their upper ends. The lower ends of the two concave plates 7 are fixedly connected to the upper ends of two pressure plates 6. Springs 11 are sleeved on the two limiting rods 10. During the process of moving the mounting plate 9 downward, the concave plates 7, limiting rods 10, springs 11 and pressure plates 6 can first achieve the effect of fixing the plastic plate conveyed to the quantitative cutting component 5, thereby increasing the stability of the device in the process of cutting the plastic plate.

[0031] Furthermore, the conveying assembly 2 includes a mounting frame 22. The upper end of the mounting frame 22 is fixedly connected to the conveying assembly 3, and the lower end of the mounting frame 22 is fixedly connected to the base plate 1. The front and rear ends of the mounting frame 22 are movably connected to the front and rear sides of two rotating rods 23, respectively. Each of the two rotating rods 23 is fixedly connected to a transmission roller 24, and the two transmission rollers 24 are connected by a conveyor belt 25. The rear ends of each of the two rotating rods 23 are fixedly connected to a sprocket 21, and the two sprockets 21 are connected by a chain. The front end of the left rotating rod 23 is fixedly connected to the output shaft of a motor 26. The motor 26 is fixedly connected to the mounting frame 22 through a motor frame. The rotation of the output shaft of the motor 26 drives the left rotating rod 23 to rotate. At this time, under the action of the two sprockets 21, the right rotating rod 23 can be driven to rotate accordingly. The rotation of the two rotating rods 23, in cooperation with the transmission rollers 24 and the conveyor belt 25, achieves the conveying process of the plastic sheet.

[0032] The conveying assembly 2 3 includes a concave frame 2 37. The lower end of the concave frame 2 37 is fixedly connected to the mounting frame 22. Two electro-hydraulic rods 2 39 are fixedly connected to the upper end of the concave frame 2 37. The lower ends of the two electro-hydraulic rods 2 39 are fixedly connected to the fixed frame 36. A motor 2 313 is fixedly connected to the upper end of the fixed frame 36. A sprocket 2 312 is fixedly connected to the output shaft of the motor 2 313. The sprocket 2 312 is connected to a sprocket 310 via another chain. The sprocket 310 is fixedly connected to a worm 35. The worm 35 meshes with two worm wheels 31. The two worm wheels 31 are fixedly connected to two rotating rods 2 32. Two transmission rollers 2 33 are fixedly connected to each of the two rotating rods 2 32. The four transmission rollers 2 33 are connected to each other via two conveyor belts 2 311. The front and rear ends of the two rotating rods 2 32 are movably connected to the front and rear ends of the fixed frame 36, respectively. Two limiting rods 2 38 are fixedly connected to the upper end of the fixed frame 36. Both 38 are movably connected to the concave frame 37 with two limiting holes at the upper end. Two support plates 34 are movably connected to the worm gear 35. The upper ends of the two support plates 34 are fixedly connected to the fixed frame 36. By starting the electric hydraulic rod 39, the fixed frame 36 is moved downward, which in turn moves the transmission roller 33 and the conveyor belt 311 downward until the lower ends of the two conveyor belts 311 overlap the upper end of the plastic sheet during the conveying process. Then, the motor 313 is started to drive the sprocket 312 to rotate. Under the action of the sprocket 310, worm gear 35 and worm wheel 31, the two rotating rods 32 can be driven to rotate. The two rotating rods 32 rotate in opposite directions to the two rotating rods 23. The rotation of the two rotating rods 32, in cooperation with the transmission roller 33 and the conveyor belt 311, increases the stability of the device during the conveying process of the plastic sheet and plays an auxiliary role in conveying the plastic sheet.

[0033] The quantitative cutting assembly 5 includes a cutting plate 52. Two fixing plates 51 are fixedly connected to the lower end of the cutting plate 52. The lower ends of both fixing plates 51 are fixedly connected to the base plate 1. The right fixing plate 51 is movably connected to one side of a threaded rod 53, and the other side of the threaded rod 53 is movably connected to a fixing plate 57. The lower end of the fixing plate 57 is fixedly connected to the base plate 1. A threaded block 55 is threaded onto the threaded rod 53. The upper end of the threaded block 55 is fixedly connected to an overlapping plate 56. An L-shaped baffle 58 is fixedly connected to the upper end of the overlapping plate 56. A detection sensor 59 is installed on the upper side of the L-shaped baffle 58. Two sliders 510 are fixedly connected to the lower end of the overlapping plate 56. The two sliders 510 are movably connected to two fixing rods 54 respectively. The left and right sides of the two fixing rods 54 are... Both ends are fixedly connected to the right-side fixed plate 51, and the right ends of the two fixed rods 54 are fixedly connected to the fixed plate 57. During the conveying of the plastic sheet, when the right end of the plastic sheet overlaps with the L-shaped baffle 58, the detection sensor 59 will activate the two electric hydraulic rods 12 to drive the mounting plate 9 and the cutting blade 8 to move downward. At this time, with the cooperation of the set cutting plate 52, the quantitative cutting process of the plastic sheet can be achieved. By rotating the threaded rod 53, with the cooperation of the set threaded block 55, slider 510 and fixed rod 54, the overlapping plate 56 can be driven to move in the left and right directions, thereby achieving the adjustment process of the horizontal distance between the cutting blade 8 and the L-shaped baffle 58, thus achieving the adjustment process of the cutting length during the cutting process of the plastic sheet.

[0034] The working principle of this utility model is as follows:

[0035] When using this device to cut plastic sheets during the manufacturing process of plastic packaging products, the plastic sheet is placed on conveyor belt 25 and motor 26 is started. The rotating rod 23, transmission roller 24, conveyor belt 25, and sprocket 21 work together to move the plastic sheet to the right. During this movement, the electro-hydraulic rod 39 is activated, causing the fixed frame 36 to move downwards. This causes the lower ends of the two conveyor belts 311 to overlap the upper ends of the plastic sheet, and motor 313 is started. The rotation of the output shaft of motor 313, along with the sprockets 312, 310, worm gear 35, worm wheel 31, rotating rod 32, and transmission roller 33, drives the two conveyor belts 311 to rotate, thus moving the plastic sheet on conveyor belt 25... With the cooperation of the two, a stable conveying process of the plastic sheet can be achieved. During the conveying process, when the right end of the plastic sheet overlaps with the L-shaped baffle 58, the detection sensor 59 can shut down motor 26 and motor 313 and start two electric hydraulic rods 12 to move the mounting plate 9 downward. Then, with the cooperation of the cutting blade 8 and the cutting plate 52, the plastic sheet can be quantitatively cut. When it is necessary to adjust the cutting length of the plastic sheet, by rotating the threaded rod 53, with the cooperation of the threaded block 55, the fixing rod 54 and the slider 510, the overlapping plate 56 can be moved in the left and right directions, thereby adjusting the horizontal distance between the cutting blade 8 and the L-shaped baffle 58, thus realizing the adjustment of the cutting length of the plastic sheet.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
