Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a head mechanism of an automatic slitting casting machine. Background Technique

[0002] A casting machine refers to a special equipment for making casting films. Using a high-precision electronic ceramic casting machine, alumina is used as the main raw material for ceramic casting. First, the crushed powder is mixed with a binder, a plasticizer, a dispersant, and a solvent to form a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and coated on a special base tape by a doctor blade with a certain thickness. After drying and curing, it is peeled off from the top to form a green tape film. Then, according to the size and shape requirements of the finished product, the green tape is punched, laminated, and other processing treatments are performed to make a blank finished product to be sintered. It has the advantages of low cost, high quality, non-toxicity, and simple production process.

[0003] Entering the 21st century, driven by the market demand for casting films, domestic casting film production equipment has made great progress, and the international competitiveness of domestic casting equipment has been increasing day by day. For example, multi-layer casting film production lines with a width of 2500mm and 3000mm have been mass-produced, and some technical indicators have reached the standards of foreign similar products.

[0004] Currently, all casting machines use single die head coating. After the slurry is put into the die head, the slurry is coated from the die lip onto the film to complete the coating work. However, if different slurries need to be coated, since the slurries cannot be mixed, it is necessary to replace different new die heads, or clean the original die head before using it, which affects the coating efficiency.

Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0022] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be intermediate elements present. On the contrary, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] As Figure 1 、 Figure 2 shown, the head mechanism of an automatic slitting casting machine includes a mounting bracket 1, two lifting cylinders 2, a sliding assembly 3, a die head rotating assembly 4, and two die heads 5. The sliding assembly 3 is mounted on the mounting bracket 1. The die head rotating assembly 4 is slidably disposed on the sliding assembly 3 and is used to drive the two die heads 5 to rotate. The two die heads 5 are respectively mounted on the top and bottom of the die head rotating assembly 4. The two lifting cylinders 2 are symmetrically disposed on the mounting bracket 1 and the telescopic rods are fixedly connected to the die head rotating assembly 4 for driving the die head rotating assembly 4 and the two die heads 5 to move axially.

[0025] As Figure 3 shown, the sliding assembly 3 includes a base 31, a slide rail 32, and a slider 33. The slide rail 32 is fixedly mounted on the base 31, and the slider 33 is slidably disposed on the slide rail 32.

[0026] As Figure 3 shown, the die head rotating assembly 4 includes two fixed seats 41, a mounting seat 42, a rotating handle 43, and a rotating shaft 44. The two fixed seats 41 are symmetrically disposed on the mounting bracket 1. The rotating shaft 44 passes through the mounting seat 42 and both ends are rotatably disposed on the two fixed seats 41 respectively. The rotating handle 43 is mounted on one end of the rotating shaft 44 and is used to drive the rotating shaft 44 to rotate and thereby drive the mounting seat 42 to rotate together. The two die heads 5 are respectively mounted on the top surface and the bottom surface of the mounting seat 42.

[0027] The base 31 is fixedly mounted on the mounting bracket 1. One of the two fixed seats 41 far from the machine shell is mounted on the slider 33. The mounting seat 42 is one of a cube structure or a cuboid structure. The mounting seat 42 is a regular graphic structure, which is convenient for the installation of the two die heads 5.

[0028] Two die heads 5 are respectively arranged at the top and bottom of the mounting base 42. The die head 5 at the top is responsible for coating the slurry on the film 40 of the coating roller 30. When it is necessary to replace different coating slurries, rotate the rotary handle 43. The rotary handle 43 drives the rotary shaft 44 to rotate synchronously. The rotary shaft 44 drives the mounting base 42 to rotate synchronously by 180°, so that the positions of the original bottom die head 5 and the original top die head 5 are switched. Start the two jacking cylinders 2. The two jacking cylinders 2 push the die head rotating assembly 4 towards the coating roller 30. One of the fixed seats 41 slides towards the coating roller 30 on the slide rail 32 through the slider 33, so that the mounting base 42 drives the two die heads 5 towards the coating roller 30 until the preset distance is reached between the switched top die head 5 and the coating roller 30. The switched top die head 5 can be filled with new slurry for film coating. The bottom die head 5 after switching can be disassembled for cleaning and then reinstalled for use.

[0029] In this way, for the head mechanism of the automatic slitting casting machine, through the cooperative setting of the two jacking cylinders 2, the sliding assembly 3, the die head rotating assembly 4, and the two die heads 5, the two die heads 5 are respectively installed at the top and bottom of the die head rotating assembly 4. When it is necessary to switch the die head 5, the die head rotating assembly 4 controls the rotation of the two die heads 5, moves the bottom die head 5 to the top. The two jacking cylinders 2 control the die head rotating assembly 4 and the two die heads 5 to slide on the sliding assembly 3, approaching or moving away from the coating roller 30, so as to adjust the distance between the die head 5 and the coating roller 30, and the rapid switching of the die head 5 can be completed. The switched die head 5 can quickly carry out the coating work, effectively ensuring the coating efficiency.

[0030] As Figure 4 shown, in one of the embodiments, in order to realize the fine adjustment of the distance between the die head 5 and the coating roller 30, the head mechanism further includes a distance adjustment assembly 6. The distance adjustment assembly 6 includes a linear motor 61, a pressing block 62, and a wedge block 63. The linear motor 61 is installed on the mounting bracket 1. One end of the pressing block 62 is fixedly connected to the output end of the linear motor 61. The wedge block 63 is fixedly installed on the die head rotating assembly 4. The top surface of the wedge block 63 is an inclined surface structure. During the process that the jacking cylinder 2 drives the die head rotating assembly 4 to move towards the distance adjustment assembly 6, the top surface of the wedge block 63 abuts against the bottom surface of the pressing block 62. During the process that the linear motor 61 drives the pressing block 62 to slide on the top surface of the wedge block 63, the die head rotating assembly 4 is driven to move axially.

[0031] In this way, when it is necessary to finely adjust the distance between the die head 5 and the coating roller 30, the linear motor 61 is started. The linear motor 61 drives the pressing block 62 to slide on the top surface of the wedge block 63. Since the top surface of the wedge block 63 is an inclined surface structure, when it is necessary to increase the distance between the die head 5 and the coating roller 30, the linear motor 61 drives the pressing block 62 to slide towards the higher surface of the wedge block 63, applying a certain pressure to the mounting seat 42, causing the mounting seat 42 to slide towards the direction of the lifting cylinder 2, and then driving the die head 5 at the top to slide towards the direction of the lifting cylinder 2 together, increasing the distance between the die head 5 at the top and the coating roller 30; when it is necessary to reduce the distance between the die head 5 and the coating roller 30, the linear motor 61 drives the pressing block 62 to slide towards the lower surface of the wedge block 63, reducing the pressure on the mounting seat 42, causing the mounting seat 42 to slide away from the direction of the lifting cylinder 2, and then driving the die head 5 at the top to slide away from the direction of the lifting cylinder 2 together, reducing the distance between the die head 5 at the top and the coating roller 30, realizing the fine adjustment of the distance between the die head 5 and the coating roller 30.

[0032] In one embodiment, in order to ensure the cleanliness of the coating roller 30 before coating, the head mechanism further includes a coating roller dust sticking assembly 7. The coating roller dust sticking assembly 7 includes a first mounting frame 71, a rotating roller 72, and a first dust sticking roller 73. The first mounting frame 71 is mounted on the machine shell 20. One end of the rotating roller 72 is fixedly connected to the first mounting frame 71, and the other end is connected to a rotating member. The first dust sticking roller 73 is rotatably arranged on the first mounting frame 71 and fits with the coating roller when the coating roller needs to be cleaned, and drives the first dust sticking roller 73 to rotate when the coating roller rotates, for sticking the dust on the coating roller 30.

[0033] In this way, when it is necessary to clean the coating roller 30, the rotating member controls the rotating roller 72 to rotate at a preset angle, and then drives the first mounting frame 71 to rotate, so that the first mounting frame 71 drives the first dust sticking roller 73 to fit with the coating roller 30. The coating roller 30 drives the first dust sticking roller 73 to rotate during rotation, sticking the dust or impurities on the coating roller 30 to the first dust sticking roller 73, ensuring the cleanliness of the coating roller 30 before coating.

[0034] In one embodiment, the head mechanism further includes a collision prevention and limit block 8. The collision prevention and limit block 8 is fixedly installed on the machine shell 20 and is located between the die head rotation assembly 4 and the coating roller 30.

[0035] In this way, the anti-collision limit block 8 can be made of a soft material. When the lifting cylinder 2 pushes the die head rotating assembly 4 to move towards the coating roller 30, when the die head rotating assembly 4 abuts against the anti-collision limit block 8, the die head rotating assembly 4 cannot continue to move towards the coating roller 30, which plays a very good limiting role. At the same time, since the anti-collision limit block 8 is made of a soft material, it can also prevent the die head rotating assembly 4 from colliding and being damaged by the anti-collision limit block 8.

[0036] In one embodiment, the head mechanism further includes a film dust sticking assembly 9. The film dust sticking assembly 9 includes a second mounting bracket 91 and a second dust sticking roller 92. The second mounting bracket 91 is mounted on the machine housing 20, and the second dust sticking roller 92 is rotatably arranged on the second mounting bracket 91.

[0037] In this way, after the film 40 is unrolled, when the film 40 moves towards the die head 5 during the rotation of the second dust sticking roller 92, the second dust sticking roller 92 is driven to rotate, so that the second dust sticking roller 92 sticks the dust or impurities on the film 40 to the second dust sticking roller 92 during rotation, keeping the film 40 to be coated clean and tidy.

[0038] In one embodiment, the head mechanism further includes a distance detector 10. The distance detector 10 is mounted on the machine housing 20 and is located between the die head 5 and the coating roller 30.

[0039] In this way, the distance detector 10 detects the distance between the die head 5 and the coating roller 30 in real time and sends the distance value to the control module. When the distance between the die head 5 and the coating roller 30 is less than or greater than a preset threshold, the control module controls the alarm unit to give an alarm, prompting the operator to detect that the distance between the die head 5 and the coating roller 30 is too close or too far, ensuring the normal progress of the coating work and the safety of the coating.

[0040] In one embodiment, the head mechanism further includes a slurry recovery tank 11. The slurry recovery tank 11 is mounted at the bottom of the mounting bracket 1.

[0041] In this way, through the setting of the slurry recovery tank 11, the slurry dropped during the coating process of the die head 5 can be recovered, avoiding the dropped slurry from contaminating the head equipment and ensuring the cleanliness of the head.

[0042] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
