Description

Technical Field

[0001] This utility model relates to the field of bag making machine manufacturing, specifically to a high-speed bag making machine with a cooling blade. Background Technology

[0002] The fully automatic bag making machine uses a servo motor to drive the feeding and control the bag length, and a frequency converter motor to drive the heating and cutting blade to cut the bag up and down. A silicone rubber roller is installed under the heat-sealing and cutting blade. The heat-sealing and cutting blade heat-seals and cuts the fed film roll material to form the bag. Due to the action of the heat-cutting blade, the support roller (rubber roller) is often damaged. At the same time, it is easy to cause heat radiation damage to the feeding device behind the cut plastic film, which affects the product quality and the life of the equipment. Utility Model Content

[0003] This invention provides a high-speed bag making machine with a cooling blade. By setting up the cooling blade, the cut-off point is cooled quickly. At the same time, it works with the hot cutting blade, which can effectively shield the feeding device from heat radiation damage caused by the hot cutting blade and improve the service life of the equipment.

[0004] This utility model is achieved through the following technical solution:

[0005] Compared with the prior art, this utility model has the following advantages:

[0006] A high-speed bag-making machine with a cooling blade includes a frame, on which a feeding device and a hot shearing device are mounted. The hot shearing device includes a hot cutting blade and a support roller. The hot cutting blade reciprocates toward the support roller to cut the film roll. A cooling blade is also provided between the hot shearing device and the feeding device. The cooling blade has cooling water holes connected to circulating water. The cooling blade moves up and down synchronously with the hot cutting blade.

[0007] Furthermore, a drive shaft B is rotatably connected to the frame, and connecting plates B are fixed at both ends of the drive shaft B. The lower end of the drive rod B is hinged to the free end of the connecting plate B, and the upper end of the drive rod B is fixedly connected to the end of the cooling blade. The drive shaft B is driven to the output end of the drive motor A, and moves up and down synchronously with the hot cutting blade under the action of the drive motor A.

[0008] Furthermore, the drive rod B is provided with an upper limit block and a lower limit block, the cooling blade is fixed on the bracket, and an outer joint bearing is fixed at both ends of the bracket. The outer joint bearing is disposed between the upper limit block and the lower limit block and passes through the drive rod B. A compression spring B is disposed between the outer joint bearing and the upper limit block.

[0009] Furthermore, a guide rod is fixedly connected below the bracket, and the guide rod is inserted into a linear bearing on the frame.

[0010] Furthermore, the cooling blade has an L-shaped side, with its lower end facing the hot cutting blade.

[0011] Furthermore, the cooling water holes are arranged along the length direction of the cooling blade.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention adds a cooling blade between the hot shearing device and the feeding device. By setting the cooling blade to move synchronously with the hot shearing blade, the contact point between the hot shearing blade and the support roller can be cooled quickly, and the plastic film after hot cutting is cooled down quickly. At the same time, it avoids heat radiation from the hot shearing blade to the feeding device, thus improving the service life of the equipment. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] like Figure 1-4 As shown, a high-speed bag-making machine with a cooling blade includes a frame 10. A feeding device 20 and a hot shearing device 30 are mounted on the frame 10. The hot shearing device 30 includes a hot cutting blade 301 and a support roller 302. The hot cutting blade 301 reciprocates toward the support roller 302 to cut the film roll. A cooling blade 50 is also provided between the hot shearing device 30 and the feeding device 20. The cooling blade 50 has a cooling water hole 501 connected to circulating water. The cooling blade 50 and the hot cutting blade 301 move up and down synchronously.

[0021] Furthermore, a drive shaft B102 is rotatably connected to the frame 10. Connecting plates B1021 are fixed at both ends of the drive shaft B102. The lower end of the drive rod B10211 is hinged to the free end of the connecting plate B1021. The upper end of the drive rod B10211 is fixedly connected to the end of the cooling blade 50. The drive shaft B102 is driven to the output end of the drive motor A101. Under the action of the drive motor A101, it moves up and down synchronously with the hot cutting blade 301.

[0022] Specifically, the synchronous up-and-down movement of the cooling blade 50 and the hot cutting blade 301 is a conventional technical method driven by two motors, which will not be described in detail here. The synchronous up-and-down movement can better shield the feeding device 20 from the heat radiation of the hot cutting blade 301.

[0023] Furthermore, the drive rod B10211 is provided with an upper limit block 10212 and a lower limit block 10213. The cooling blade 50 is fixed on the bracket 503. An outer joint bearing 5031 is fixed at both ends of the bracket 503. The outer joint bearing 5031 is disposed between the upper limit block 10212 and the lower limit block 10213 and passes through the drive rod B10211. A compression spring B5032 is disposed between the outer joint bearing 5031 and the upper limit block 10212.

[0024] Specifically, by setting the upper limit block 10212 and the lower limit block 10213, the cooling blade 50 can effectively fit against the support roller 302 when it moves downward. At the same time, when the cooling blade 50 contacts the support roller 302, the compression spring B5032 can ensure that the lower end face of the cooling blade 50 is in contact with the support roller 302, thereby cooling it down, reducing damage to it by the hot cutting blade 301, and improving its service life.

[0025] Furthermore, in order to ensure the stability of the movement of the cooling blade 50, a guide rod 502 is fixedly connected below the bracket 503, and the guide rod 502 is inserted into the linear bearing on the frame 10.

[0026] Furthermore, the cooling blade 50 is L-shaped on its side, with its lower end facing the hot cutting blade 301. This arrangement allows the free end of the cooling blade 50 to be positioned close to the cutting position of the hot cutting blade 301, while also providing better shielding for the feeding device.

[0027] Furthermore, the cooling water holes 501 are arranged along the length of the cooling blade 50, which can achieve the overall cooling effect of the cooling blade 50.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
