Description

Technical Field

[0001] This invention relates to the field of sponge foaming technology, and in particular to a foaming height adjustment device. Background Technology

[0002] When foaming sponges, the foaming material (such as polyurethane foaming material) is usually poured onto the insulating substrate using the pouring head of the pouring machine. Then, the foaming material is evenly coated onto the insulating substrate by the coating roller on the coating machine. The foaming material then foams freely on the insulating substrate to obtain the sponge. After the sponge is dried, it is cut, rolled up and packaged.

[0003] In the sponge manufacturing process, existing coating machines can achieve uniform coating of foaming materials such as polyurethane, and control the foaming height to produce sponges of specific heights by adjusting the amount of foaming material added or changing the foaming material formula. However, adjusting the amount of foaming material added cannot meet the requirements of specific sponge foaming density and cell size, and changing the foaming material formula requires investment of research and development time and economic costs. In view of this, some researchers have tried to achieve limited foaming of sponges of specific heights by using the foaming box structure of the coating machine without changing the amount of foaming material added or the formula. However, due to the gaps in the side walls of the foaming box, foaming material leakage is prone to occur, leading to foaming failure; or the upper end of the foaming box is prone to collision with the coating roller, making it impossible to change the foaming height, and only one height of foaming can be produced, which greatly limits the foaming of sponges. Summary of the Invention

[0004] In view of the problem that in the prior art, without changing the amount of foaming material added and the formula, the foaming height cannot be changed because there are gaps on the side wall of the foaming box of the coating machine or the upper end of the foaming box is prone to collision with the coating roller, and foaming can only be performed at one height, which greatly limits the foaming of the sponge, the present invention is proposed.

[0011] In a preferred embodiment of the foaming height adjustment device of the present invention, the guide component includes an inclined groove disposed on the height limiting box, an inclined block slidably connected in the inclined groove, a guide rod fixedly connected on the inclined block, a lifting rod fixedly connected on the lifting plate, and the lifting rod being fixedly connected to the inclined block.

[0012] In a preferred embodiment of the foaming height adjustment device of the present invention, the transmission component includes a movable plate disposed on the front side of the height limiting box, the movable plate having two strip-shaped openings, a hollow cylinder with an open upper end fixedly connected to the movable plate, an L-shaped rod slidably connected inside the hollow cylinder, a connecting seat fixedly connected to the L-shaped rod, a support plate rotatably connected to the connecting seat, and the support plate rotatably connected to the guide rod.

At the same time, an anti-collision component is also set, which can automatically adjust the left and right position of the height limiting plate when the limiting plate rises, always keeping the height limiting plate inside the coating roller, preventing collisions between the height limiting plate and the coating roller. This solves the problem that, without changing the amount and formula of foaming material, the foaming height cannot be changed due to gaps in the side wall of the foaming box of the coating machine or the upper end of the foaming box easily colliding with the coating roller, which greatly limits the foaming of the sponge. The present invention achieves the effect of changing the foaming height limit, preventing the foaming material from leaking out from the front and rear ends, and ensuring that the height limiting plate does not collide with the coating roller.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1 Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a foaming height adjustment device that can adjust the foaming height. It includes a conveying component 100, comprising a main conveyor belt 101, a lower release paper 102 disposed on the main conveyor belt 101, an upper release paper 103 disposed above the lower release paper 102, a coating roller 104 and a transfer roller 105 disposed above the main conveyor belt 101, a casting head 106 disposed on one side of the coating roller 104, and a height limiting box 107 disposed between the coating roller 104 and the transfer roller 105; and an adjustment component 200. The components include a lifting assembly 201 mounted on the height restriction box 107, a filling assembly 202 mounted on the lifting assembly 201, a squeezing assembly 203 mounted on the filling assembly 202, and a scraping assembly 204 mounted on the height restriction box 107; and a collision avoidance component 300, which includes a guide assembly 301 mounted on the height restriction box 107, a transmission assembly 302 mounted on the guide assembly 301, a folding assembly 303 mounted on the transmission assembly 302, an elastic assembly 304 mounted on the height restriction box 107, and a guide assembly 305 mounted on the elastic assembly 304.

[0032] Specifically, the lower end of the main conveyor belt 101 is equipped with a support and a conveyor roller for the main conveyor belt 101 to move. The conveyor roller is equipped with a motor to provide power for the movement of the main conveyor belt 101. The main conveyor belt 101 extends into the height limit box 107. The upper end of the main conveyor belt 101 is covered with a lower release paper 102 and an upper release paper 103 at the top to prevent the foam from sticking together when it moves from the height limit box 107. The pouring head 106 can pour the foam material, and the coating roller 104 can coat the foam material evenly. This is prior art and will not be described in detail here.

[0033] Furthermore, the lifting assembly 201 includes a mounting groove 201a disposed on the height limiting box 107, an electric telescopic rod 201b fixedly connected in the mounting groove 201a, and a lifting plate 201c fixedly connected to the telescopic end of the electric telescopic rod 201b; the filling assembly 202 includes a first rubber sheet 202a fixedly connected to the height limiting box 107, a second rubber sheet 202b fixedly connected to the first rubber sheet 202a, a third rubber sheet 202c fixedly connected to the second rubber sheet 202b, and a lifting plate 201c provided with There is an inclined surface 202d, and a second rubber sheet 202b is attached to the inclined surface 202d; the extrusion assembly 203 includes a first folding plate 203a fixedly connected to the lifting plate 201c, a second folding plate 203b fixedly connected to the first folding plate 203a, a height limiting plate 203c provided on the upper side of the height limiting box 107, a bearing block 203d fixedly connected to the height limiting plate 203c, the bearing block 203d being fixedly connected to the lifting plate 201c, and a pressure strip 203e cooperating with the first rubber sheet 202a provided on the height limiting plate 203c.

[0034] It should be noted that multiple mounting slots 201a are provided, and electric telescopic rods 201b are fixedly connected in each of the multiple mounting slots 201a. The lifting plate 201c is set between the height limiting plate 203c and the height limiting box 107. The first rubber sheet 202a is set vertically, the second rubber sheet 202b is set at an angle, and the third rubber sheet 202c has an arc. The lengths of the first rubber sheet 202a, the second rubber sheet 202b, and the third rubber sheet 202c are all equal to the length of the height limiting box 107, and the third rubber sheet 202c extends to the outer end of the height limiting box 107. The second folding plate 203b abuts against the outer wall of the third rubber sheet 202c. The lifting plate 201c and the pressure strip 203e press the connection between the first rubber sheet 202a and the second rubber sheet 202b from the upper and lower directions, respectively.

[0035] During use, the coating width is 800mm, and the mechanical transmission speed of the main drive belt is 2m / min (there are no restrictions on the coating width and mechanical transmission speed; production can be achieved as long as the casting machine can produce the foaming material per unit time). The foaming material is poured onto the lower release paper via the casting head 106. The lower and upper release papers move uniformly towards the coating roller 104 at the same speed. After passing the coating roller, the foaming material is rolled to a specified thickness and enters the limiting channel. At this time, the upper release paper is above the foaming material, the lower release paper is below it, and the sides are connected to the side limiting synchronous belt 204b. The traction speed of the upper and lower release papers is the same as that of the side limiting synchronous belt 204b, ensuring that the material is relatively stationary with each contact surface within the limiting channel, ensuring the stability of the foaming process, and providing the power to overcome the friction between the upper and lower release papers and the limiting channel.

[0036] During use, the foaming height of the foamed material is limited by the height restriction plate 203c. When the height restriction plate 203c needs to be raised or lowered, the electric telescopic rod 201b extends, causing the lifting plate 201c to move upward. The bearing block 203d then causes the height restriction plate 203c to move upward, thereby changing the height of the height restriction plate 203c and thus changing the maximum foaming height. When the lifting plate 201c moves upward, it can push the second rubber sheet 202b, increasing the height of the first rubber sheet 202a. The third rubber sheet 202c fills the second rubber sheet 202b. Since the side wall of the first rubber sheet 202a abuts against the side wall of the lifting plate 201c, the first rubber sheet 202a is kept vertical to fill the gaps and prevent the foamed material from leaking out of the height restriction box 107. At the same time, the thickness of the lateral limiting synchronous belt 204b can be changed when foaming at different heights.

[0037] In summary, by adjusting the movement of the first rubber sheet 202a, the second rubber sheet 202b, and the third rubber sheet 202c, the length of the first rubber sheet 202a, the second rubber sheet 202b, and the third rubber sheet 202c can be adjusted to ensure that the side can still be sealed when the height limit plate 203c is raised, thus guaranteeing the sealing effect. This allows the height of the height limit plate 203c to be changed, thereby changing the foaming height.

[0038] Example 2 Reference Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a scraping assembly 204 for the foaming height adjustment device, solving the problem of how to clean the side-limiting synchronous belt 204b. It includes a rotating shaft 204a disposed on the coating roller 104, a side-limiting synchronous belt 204b disposed on the rotating shaft 204a, a release agent brush 204c disposed above the side-limiting synchronous belt 204b, and a scraper 204d disposed on the inner side of the side-limiting synchronous belt 204b. The rotating shaft 204a is fixedly connected to the coating roller 104, and a connecting disc is fixedly connected to the rotating shaft 204a. The side-limiting synchronous belt 204b is connected via a connecting disc... The receiving plate is used for transmission. At the same time, in order to solve the problem that the liquid foaming material does not soak into the gap between the limiting rubber strip and the existing molding cavity, which affects the operation of the entire machine, the lengths of the lower isolation paper 102 and the upper isolation paper 103 are both greater than the width of the limiting molding cavity. The upper isolation paper 103 bends inward with the cavity on both sides to completely cover the gap between the side limiting synchronous belt 204b and the existing molding cavity, ensuring the normal operation of the instrument. When adjusting the height limiting plate 203c on the height limiting box 107, it needs to be done in the stopped state. At this time, different side limiting synchronous belts 204b can be replaced according to different heights, always ensuring that the side limiting synchronous belt 204b can reach the entire side wall of the foaming.

[0039] During use, a release agent brush 204c is provided at the beginning of the circulation of the side limiting synchronous belt 204b to prevent the foaming material from sticking to the side limiting synchronous belt 204b. Two scrapers 204d are fixed to the lower surface of the limiting channel at the end of the limiting channel. Their blades are opposite to the direction of movement of the side limiting synchronous belt 204b. When the foaming material passes through the scrapers 204d, the excess material adhering to the side limiting synchronous belt 204b is removed, so that the side limiting synchronous belt 204b remains clean and participates in the next limiting foaming process.

[0040] In summary, by setting up the release agent brush 204c and the scraper 204d, the side limiting synchronous belt 204b can be cleaned, removing the excess material adhering to the side limiting synchronous belt 204b, ensuring the cleanliness of the side limiting synchronous belt 204b, and ensuring the cleaning effect of the side limiting synchronous belt 204b.

[0041] Example 3 Reference Figures 7-9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an anti-collision component 300 for the foaming height adjustment device, solving the problem of how to prevent the height-limiting plate 203c from colliding with the coating roller 104 when it moves upwards. Its guide assembly 301 includes an inclined groove 301a disposed on the height-limiting box 107, an inclined block 301b slidably connected within the inclined groove 301a, a guide rod 301c fixedly connected to the inclined block 301b, and a lifting rod 301d fixedly connected to the lifting plate 201c, the lifting rod 301d being fixedly connected to the inclined block 301b; the transmission assembly 302 includes components disposed on the height-limiting box 107. The movable plate 302a on the front side of the high box 107 has two strip-shaped openings 302b. A hollow cylinder 302c with an open top is fixedly connected to the movable plate 302a. An L-shaped rod 302d is slidably connected inside the hollow cylinder 302c. A connecting seat 302e is fixedly connected to the L-shaped rod 302d. A support plate 302f is rotatably connected to the connecting seat 302e. The support plate 302f is rotatably connected to the guide rod 301c. Here, the guide rod 301c passes through the strip-shaped openings 302b and extends to the outside of the movable plate 302a. Here, the connecting seat 302e is located on the upper side of the hollow cylinder 302c.

[0042] Furthermore, the folding assembly 303 includes multiple through-holes 303a disposed on the height restriction plate 203c, the multiple through-holes 303a dividing the height restriction plate 203c into multiple strip plates 303b, the multiple strip plates 303b being connected by hinges 303c, and the L-shaped rod 302d being fixedly connected to the middle strip plate 303b; the elastic assembly 304 includes a mounting cylinder 304a fixedly connected to the moving plate 302a, a baffle 304b being slidably connected inside the mounting cylinder 304a, the baffle 304b being spring-loaded against the inner wall of the mounting cylinder 304a by a spring 304c. The connection is as follows: a push rod 304d is fixedly connected to the baffle 304b, which passes through the mounting cylinder 304a; the guide assembly 305 includes a limiting piece 305a fixedly connected to the push rod 304d, a drive shaft 305b rotatably connected to the limiting piece 305a, and a pressing roller 305c fixedly connected to the drive shaft 305b; the width of the multi-segment strip plates 303b is equal, and the hinge 303c here is a 180° hinge 303c, which allows the bottoms of two adjacent strip plates 303b to touch; the mounting cylinder 304a and the hollow cylinder 302c are at the same height.

[0043] In use, when the lifting plate 201c rises, it drives the lifting rod 301d upward, which in turn drives the inclined block 301b upward. As the inclined block 301b rises, it drives the moving plate 302a upward, causing the hollow cylinder 302c, L-shaped rod 302d, and height-limiting plate 203c to rise simultaneously (in this case, the L-shaped rod 302d remains stationary with respect to the hinge 303c). However, when the inclined block 301b rises, due to the cooperation between the inclined block 301b and the inclined groove 301a, the inclined block 301b moves towards the center, causing the guide rod 301c to move towards the center, which in turn moves the support plate 302f, pushing the connecting seat 302e upward. This, in turn, gives the L-shaped rod 302d a displacement, causing it to move upward. As the L-shaped rod 302d moves upward, it drives the hinge 303c in the middle position upward, which in turn drives the middle strip plate 303b upward. When 303b moves upward, due to the squeezing of the extrusion roller 305c, the edge strip plate 303b fills the gap in the middle without detaching from the height limit plate 203c. At the same time, the extension height of the electric telescopic rod 201b is just enough for the hinge 303c to lift the width of one strip plate 303b each time, thus squeezing the edge strip plate 303b in the middle. After squeezing, it can still ensure the abutment of the side walls of the two strip plates 303b, preventing the foam from getting stuck in the gap between the two strip plates 303b. At the same time, as the strip plates 303b at both ends move towards the middle, the left and right limit positions of the height limit plate 203c change, moving towards the middle. Thus, when the height limit plate 203c moves upward, it will not collide with the coating roller 104. In addition, the extrusion roller 305c can rotate, making it less likely for the extrusion roller 305c to get stuck with the hinge 303c.

[0044] In summary, while the lifting plate 201c rises and drives the height-limiting plate 203c, it can also drive the inclined block 301b to move, causing the L-shaped rod 302d to move, thereby moving the strip plate 303b upward to adjust the gap between the left and right ends of the height-limiting plate 203c and the coating roller 104, ensuring sufficient distance and preventing collisions between the height-limiting plate 203c and the coating roller 104.
