Description

Technical Field

[0002] After hot pressing, drying and shaping, pulp molded products need to be trimmed to remove the irregular burrs on the outer edges of the products. At present, pulp molded products are often trimmed using circular cutting equipment, but when cutting high-sized products, the existing circular cutting equipment has a long knife bar and severe knife shaking, which is easy to cause cutting errors. In addition, due to the lack of necessary protective mechanisms, the cut paper scraps are easy to splash, which poses certain safety hazards. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a high-table circular cutting machine, which improves the cutting safety and the cutting accuracy of high-sized products.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a high-surface circular cutting machine, comprising

[0005] The machine platform is provided with a loading station and a cutting station, and the loading station is provided with a loading port for products to enter and exit;

[0006] The material transfer mechanism comprises a jig carrier that can reciprocate between the loading station and the cutting station, and the jig carrier is used to place the product;

[0007] A protective mechanism, located at the loading station, comprising a protective door panel that can be lifted and moved to open and close the loading port;

[0008] The cutting mechanism is located at the cutting station and includes a tool that can be raised and lowered and moved. The tool includes a rotating spindle, a tool rod group and a blade. The tool rod group includes at least two tool rods arranged from top to bottom and with radial dimensions decreasing successively. Any two adjacent tool rods are connected by a coaxial connector; and the tool rod located at the top is coaxially connected to the rotating spindle, and the tool rod located at the bottom is coaxially connected to the blade.

[0009] First, move the jig carrier to the loading station, and place the product to be cut on the jig carrier. Then, by moving the jig carrier, move the product to be cut to the cutting station. Start the protective mechanism to close the loading port, and then start the cutting mechanism to perform edge trimming operations on the product.

[0010] The beneficial effects of the utility model are:

[0011] By opening and closing the feeding port through the protective mechanism, the cutting mechanism can perform the trimming operation of the product in a relatively closed environment, thereby avoiding the injury to the workers at the feeding station caused by the cut paper scraps flying out from the feeding port, thereby improving the safety of cutting; in the cutting mechanism, the tool bar group composed of multiple tool bars not only ensures that the overall length of the tool bar group can meet the cutting requirements, but also can utilize the segmented structure to cooperate with the coaxial connection of the coaxial connector to improve the coaxiality of each tool bar in the tool bar group and reduce the shaking amplitude of the tool bar group during rotation; and the radial dimensions of each tool bar are limited to decrease from top to bottom in sequence, so that the end of the tool bar group closer to the rotating main axis is thicker, and the end farther from the rotating main axis (the end connected to the blade) is thinner, so as to reduce the shaking amplitude of the end farther from the rotating main axis during rotation, thereby improving the cutting accuracy of the blade.

[0012] Furthermore, it also includes a transverse movement mechanism located at the cutting station, the transverse movement mechanism includes a transverse movement frame, the transverse movement frame is provided with a guide rail assembly along a direction perpendicular to the moving direction of the jig carrier, and the cutting mechanism is slidably arranged on the guide rail assembly.

The transverse plate can be guided to move in two vertical directions by the sliding connection between the transverse plate and the first guide rail and the second guide rail, further enhancing the transverse movement stability of the transverse plate, thereby ensuring the stability of the transverse movement of the entire cutting mechanism.

[0014] Furthermore, a lifting plate capable of lifting and lowering is slidably provided on one side of the transverse moving plate toward the feeding port, and the tool is mounted on the lifting plate.

[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0037] Example

[0038] See attached Figure 1 , 2 As shown in Figure 5, a high-surface circular cutting machine of the utility model includes a machine table 1, a material transfer mechanism 2, a protective mechanism 3, and a cutting mechanism 4, wherein the machine table 1 is provided with a loading station, a cutting station, and an outer cover 5 arranged at the loading station and the cutting station, and the outer cover 5 is provided with a loading port 51 for the product to enter and exit near the loading station. The material transfer mechanism 2 includes a jig carrier plate 21 that can reciprocate between the loading station and the cutting station, and the jig carrier plate 21 is used to place the product. The protective mechanism 3 is located at the loading station, and includes a protective door panel 31 that can be lifted and moved to open and close the loading port. The cutting mechanism 4 is located at the cutting station, and includes a tool 41 that can be lifted and moved, and the tool 41 is used to cut the product.

[0039] For details, see the attached Figure 5 As shown, the tool 41 includes a rotating spindle 411, a tool rod group and a blade 412. The tool rod group includes at least two tool rods 413 arranged from top to bottom and with radial dimensions decreasing successively. Any two adjacent tool rods 413 are connected by a coaxial connector 414; and the tool rod 413 located at the top is coaxially connected to the rotating spindle 411, and the tool rod 413 located at the bottom is coaxially connected to the blade 412.

[0040] During operation, first move the jig carrier 31 to the loading station, and place the product to be cut on the jig carrier 31, and then move the product to be cut to the cutting station by moving the jig carrier 31; start the protection mechanism 3 to close the loading port 51, and then start the cutting mechanism 4 to make the tool 41 descend to the position where the product is to be cut, rotate the main shaft 411 to drive the tool rod group to rotate, and then make the blade 412 rotate to cut the product.

[0041] By opening and closing the feeding port 51 by the protection mechanism 3, the cutting mechanism 4 can perform the trimming operation of the product in a relatively closed environment, thereby avoiding the injury to the workers at the feeding station caused by the cut paper scraps flying out from the feeding port 51, thereby improving the safety of cutting; in the cutting mechanism 4, the tool bar group composed of multiple tool bars 413 not only ensures that the overall length of the tool bar group can meet the cutting requirements, but also can utilize the segmented structure to cooperate with the coaxial connection of the coaxial connector 414 to improve the coaxiality of each tool bar 413 in the tool bar group, and reduce the shaking amplitude of the tool bar group during rotation; and limit the radial dimensions of each tool bar 413 to decrease from top to bottom, so that the end of the tool bar group closer to the rotating main shaft 411 is thicker, and the end farther from the rotating main shaft 411 (the end connected to the blade) is thinner, so as to reduce the shaking amplitude of the end farther from the rotating main shaft 411 during rotation, thereby improving the cutting accuracy of the blade 412.

[0042] In actual application, multiple sets of independently operated material transfer mechanisms 2 can be set between the loading station and the cutting station, and multiple sets of cutting mechanisms 4 can be set accordingly, so that multiple products can be trimmed at the same time to improve work efficiency. For example, two sets of material transfer mechanisms 2 are set on the machine 1, and correspondingly, two sets of cutting mechanisms 4 are also set.

[0043] In some embodiments, see Appendix Figure 2-3 As shown, the machine 1 is also provided with a transverse movement mechanism 6 at the cutting station, and the transverse movement mechanism 6 includes a transverse movement frame 61, and the transverse movement frame 61 is provided with a guide rail assembly along a direction perpendicular to the moving direction of the fixture carrier 21, and the cutting mechanism 4 is slidably arranged on the guide rail assembly. The transverse movement of the cutting mechanism 4 is realized by the setting of the transverse movement mechanism 6, so as to facilitate the cutting operation of the cutting mechanism 4 on different positions of the product.

[0044] Furthermore, in order to improve the movement stability of the cutting mechanism 4, in some embodiments, see the attached Figure 4 As shown, the guide rail assembly includes a first guide rail 62 and a second guide rail 63 arranged in parallel, the first guide rail 62 is located on the upper end surface of the transverse frame 61, and the second guide rail 63 is located on the side surface of the transverse frame 61; and the cutting mechanism 4 is slidably connected to the first guide rail 62 and the second guide rail 63. The first guide rail 62 and the second guide rail 63 are respectively arranged on the upper end surface and the side surface of the transverse frame 61, so that the guide rail assembly can guide the cutting mechanism 4 to move in two vertical directions, thereby further enhancing the movement stability of the cutting mechanism 4.

[0045] It should be noted that, when multiple sets of cutting mechanisms 4 are provided, the multiple sets of cutting mechanisms 4 can be provided on the transverse moving frame 61 at the same time.

[0046] In some embodiments, see Appendix Figure 4-5As shown, the cutting mechanism 4 includes a transverse plate 42 slidably arranged on the first guide rail 62 and the second guide rail 63. A lifting plate 43 capable of lifting and lowering is slidably arranged on the side of the transverse plate 42 facing the feeding port 51, and a tool 41 is mounted on the lifting plate 43. Furthermore, the transverse plate 42 is a T-shaped structure, and a reinforcing rib plate is fixedly connected to the corner of the transverse plate 42 to enhance the structural stability of the transverse plate 42.

[0047] Furthermore, a cold air gun 44 is provided on the lifting plate 43 and is located on one side of the cutter 41. The air outlet of the cold air gun 44 is arranged downward to blow air to the product. The cold air gun 44 can cool down the blade 41 and the cutting part of the product, and can also blow away the paper scraps located at the cutting part of the product, thereby ensuring smooth cutting.

[0048] It should be noted that, in the tool 41, only the rotating spindle 411 is installed on the lifting plate 43, while the tool bar assembly and the blade 412 are not connected to the lifting plate 43. In addition, the rotating spindle 411 can be a rotating motor.

[0049] In some embodiments, the machine 1 is provided with a loading slide rail 22 arranged along the moving direction of the jig carrier 21, and the machine 1 is provided with a vacuum pump 7 located below the loading slide rail 22. The jig carrier 21 is slidably arranged on the loading slide rail 22 and is connected to the vacuum pump 7. The jig carrier 21 can be vacuumed by the vacuum pump 7, so that the product on the jig carrier 21 can be firmly adsorbed on the jig carrier 21 under the action of negative pressure.

[0050] In some embodiments, see Appendix Figure 3 , 6 As shown, the protection mechanism 3 includes a protection frame 32 installed on the machine platform 1, and an opening is provided on the protection frame 32 above the loading slide rail 22, and the opening is connected to the loading port 51. The protection door plate 31 is located at the opening and is connected to the protection cylinder 33 installed on the protection frame 32. The protection cylinder 33 drives the protection door plate 31 to move up and down to realize the opening and closing, thereby realizing or cutting off the connection between the opening and the loading port 51.

[0051] Since the cutter 41 is used to trim the side of the product, in order to avoid the product from being deflected due to the cutting of the cutter 41, in some embodiments, see the attached Figure 6 As shown, a material pressing assembly is also provided on the side of the protective frame 32 facing the cutting station, and the material pressing assembly includes a material pressing plate 82 that can be lifted and lowered under the action of a material pressing cylinder 81, and the material pressing plate 82 is used to press against the product located at the cutting station. The pressing of the product by the material pressing assembly can effectively prevent the product position from shifting during the cutting process.

[0052] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model.
