Description

Technical Field

[0001] This invention relates to the technical field of flushable toilet brush head production equipment, and more particularly to a flushable toilet brush forming device. Background Technology

[0002] Flushable toilet brush heads, also known as disposable toilet brushes, are produced by unwinding, folding, adding liquid, drying, shaping, and packaging flushable paper. This process is highly efficient and can meet the needs of mass production.

[0003] During the forming process, the paper is processed by a flushable toilet brush forming device. The existing flushable toilet brush forming device includes a molding module, which includes an upper mold and a lower mold. The flushable paper is conveyed between the upper mold and the lower mold. The upper mold operates and cuts the paper with a set of cutters on the upper mold, while the lower mold provides support during the process.

[0004] In the process of using existing flushable toilet brush forming devices, the paper sheets of the flushable toilet brush heads produced by the forming blade assembly have poor bonding stability and are prone to delamination. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flushable toilet brush forming device.

[0006] This invention is achieved through the following technical solution: a flushable toilet brush forming device, comprising a feeding module, a molding module, and a discharging module. The feeding module includes a feeding conveyor belt, through which the dried paper towels are conveyed to the molding module; The compression molding module includes an upper mold and a lower mold. The upper mold is connected to a press. A forming knife set is provided on the upper mold, and a top mold knife set that cooperates with the forming knife set is provided on the lower mold. The discharge module includes a discharge conveyor belt, on which the molded, flushable toilet brush head is pushed along with the remaining material.

[0007] Furthermore, the forming blade assembly includes an upper blade holder, on which downward slitting blades, kerf blades, and extrusion blades are disposed. The slitting blades include two transverse blades and one longitudinal blade. The transverse blades are connected to the longitudinal blades via a stress-relieving blade. The stress-relieving blade includes a stress-relieving section with an arc-shaped cross-section.

[0008] Furthermore, the transverse blade and / or longitudinal blade are provided with a breakpoint structure, which connects two adjacent flushable toilet brush heads during the molding process.

[0009] Furthermore, the top die assembly includes a top post directly opposite the extrusion blade.

[0010] Furthermore, the cross-section of the extrusion blade is rectangular, and the outer diameter of the top post is greater than the outer diameter of the extrusion blade.

[0011] Furthermore, the slitting blade is provided with an anti-slip structure, which includes an arc-shaped portion disposed on the slitting blade.

[0012] The beneficial effects of this invention are as follows: When the toilet brush head is flushed by squeezing it from top to bottom with the extrusion blade, the lower layer of paper cannot be effectively squeezed, which leads to the lower layer of paper easily falling off. It is necessary to adjust the length of the extrusion blade multiple times. When the extrusion blade is too long, it is easy to damage the rubber buffer layer. The top post is designed with an outer diameter of 1.2-1.5 times that of the extrusion blade. During the molding and cutting process, the top post presses out a groove under the folded paper, which then cooperates with the extrusion blade to fully connect the entire stack of multiple layers of paper.

Detailed Implementation

[0015] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 like Figure 1-6 As shown, a flushable toilet brush molding device is used to produce flushable toilet brush heads, including a feeding module, a molding module, and a discharging module. The feeding module includes a feeding conveyor belt 4. The paper that can be broken down passes through the unwinding unit 1 and the folding unit 2 to obtain folded paper. In the folding unit 2, toilet cleaner is sprayed through the spray pipe, and then the paper is dried by the dryer 3 to preliminarily shape the folded paper. The dried paper towel is then conveyed to the molding module by the feeding conveyor belt 4.

[0018] The compression molding module includes an upper mold and a lower mold. The upper mold includes a connecting column 8, the upper end of which is connected to a press, thereby driving the upper mold to move downward. A forming blade assembly 10 is installed on the upper mold. The forming blade assembly 10 includes an upper blade holder 9, which is connected to a connecting seat 24 via the connecting column 8. A connecting hole 14 is machined on the upper blade holder 9, which is a bolt hole. The upper blade holder 9 is detachably installed to the connecting seat 24 via the bolt hole 14 and bolts, facilitating replacement and maintenance. A downward slitting blade, a cutting blade 18, and an extrusion blade 19 are fixedly installed on the upper blade holder 9. During the fixed installation process, they can be fixed by welding. Since the blades are consumable parts, they can also be... First, blade slots are machined on the upper blade holder. After inserting the slitting blade, cutting blade 18, and extrusion blade 19 into the corresponding blade slots, they are fixed with polyurethane adhesive for easy replacement. The slitting blade includes two transverse blades 15 and one longitudinal blade 16. The transverse blades 15 extend to the edge of the folded paper, thereby molding and cutting the folded paper on the side to obtain a molded flushable toilet brush head. In this embodiment, there are two rows of slitting blades. Two adjacent groups of slitting blades in the same row share a transverse blade 15, and two corresponding groups of slitting blades in the two rows share a longitudinal blade 16, thereby enabling the simultaneous molding and cutting of multiple flushable toilet brush heads.

[0019] In this embodiment, the transverse blade 15 and the longitudinal blade 16 are machined with a break point structure. During the molding process, the break point structure connects two adjacent flushable toilet brush heads. The break point structure includes a gap 21 machined on the transverse blade 15 and the longitudinal blade 16. During the molding and cutting process, the folded paper at the gap 21 is not cut, thus forming a connection point between two adjacent flushable toilet brush heads. In subsequent packaging, multiple flushable toilet brush heads are packaged together. During use, the connection point is broken. During the test, it was also found that the break point structure can make the top layer of paper continuous. During the upward reset of the forming blade assembly 10, the top layer of paper will not move upward with the forming blade assembly 10, thereby improving the flatness of the flushable toilet brush head. In addition, during the molding and cutting process, the edge of the flushable toilet brush head is not completely molded and cut, thus avoiding excessive compression and deformation of the edge of the flushable toilet brush head, making it easier to spread out during use.

[0020] During use, it was found that the design of the break point structure reduced the structural strength of the transverse blade 15 and the longitudinal blade 16, especially the longitudinal blade 16 located in the middle position, which is prone to deflection. After deflection, the resistance increases rapidly, which leads to blade damage. In this embodiment, the transverse blade 15 is connected to the longitudinal blade 16 through a stress-relieving blade. The stress-relieving blade includes a stress-relieving part 17 with an arc-shaped cross-section. Specifically, the stress-relieving blade has an "S"-shaped cross-section and two stress-relieving parts 17 with opposite arc directions, which can greatly improve the anti-tilting performance. In addition, after the stress-relieving blade is introduced, the stress-relieving blade forms a cutting area, which can disperse the edge of the clamping end of the toilet brush head, which has an arc-shaped structure to avoid sharp corners, thereby avoiding the fragmentation caused by disturbance during transportation. It can also be easily connected to the toilet brush handle, while reducing the amount of material used.

[0021] The lower mold is equipped with a top mold blade assembly that cooperates with the forming blade assembly 10. In this embodiment, the lower mold includes a support frame 20, which is connected to the machine frame to control the height of the lower mold. A support base 25 is installed on the support frame 20, and a lower blade holder 11 is installed on the support base 25 by bolts. The top mold blade assembly includes a top post 22 facing the extrusion blade 19. The extrusion blade has a rectangular cross-section, and the outer diameter of the top post 22 is larger than the outer diameter of the extrusion blade 19. The extrusion blade 19 connects the clamping ends of the flushable toilet brush head together, thereby preventing separation during storage and transportation. Tests revealed that when the toilet brush head was flushed by pressing down on the extrusion blade 19 from top to bottom, the lower layer of paper could not be effectively compressed, causing it to easily fall off. The length of the extrusion blade 19 needed to be adjusted multiple times. When the extrusion blade 19 was too long, it could easily damage the rubber buffer layer 12. A top post 22 was designed, with an outer diameter 1.2-1.5 times that of the extrusion blade 19. During the molding and cutting process, the top post 22 pressed out a groove under the folded paper, which then cooperated with the extrusion blade 19 to ensure that the multi-layered paper was fully connected after molding.

[0022] The slitting blade 18 is connected to an anti-slip structure, which includes an arc-shaped part integrally formed on the slitting blade 18. In this embodiment, the cross-section of the slitting blade 18 is "S" shaped, and multiple slitting blades 18 are parallel to each other. Adjacent slitting blades 18 cut to obtain adjusting bristles. The strip bristles obtained by slitting are S-shaped. During the process of the forming blade assembly 10 resetting upward, the uppermost strip bristles will not fold upward, thereby reducing tearing. The deformation resistance of the slitting blade 18 is improved. During use, the strip bristles are dispersed and cover a larger area, resulting in better performance.

[0023] A blade retraction auxiliary structure is also installed on the upper blade holder 9. During the molding and cutting of folded paper by the forming blade assembly 10, the blade retraction auxiliary structure is compressed. During the upward reset of the forming blade assembly 10, the blade retraction auxiliary structure is elastically reset, thereby pushing the paper away from the forming blade assembly 10. In this embodiment, the blade retraction auxiliary structure is made of sponge layer 13. The height of sponge layer 13 is 1 / 2 of the height of forming blade assembly 10. Sponge layer 13 is adhered to the upper blade holder 9 by polyurethane adhesive.

[0024] A rubber buffer layer 12 is installed on the lower blade holder 11 via countersunk bolts. The discharge module includes a discharge conveyor belt 6. The molded, flushable toilet brush head is pushed onto the discharge conveyor belt 6 along with the remaining material. In this embodiment, the upper surfaces of the rubber buffer layer 12, the feeding conveyor belt 4, and the discharge conveyor belt 6 are at the same height. The folded paper moves onto and out of the rubber buffer layer 12 under the thrust of the feeding conveyor belt 4 without additional power. The height of the top column 22 is slightly lower than the height of the rubber buffer layer 12 to avoid interfering with the movement of the folded paper. During the molding and cutting of the folded paper by the forming blade assembly 10, the rubber buffer layer 12 is deformed by downward compression and then elastically returns to its original position. After a period of use, it undergoes fatigue deformation and needs to be disassembled and replaced. During the testing process, it was found that... Because the top post 22 is surrounded by a rubber buffer layer 12, it is difficult for the top post 22 to fully compress the folded paper. In this embodiment, there is a relief groove 23 at the rubber buffer layer 12 at the corresponding position of the top post 22. The aperture value of the relief groove 23 is 3-4 times the outer diameter value of the top post 22, thereby reducing the support force of the rubber buffer layer 12 on the folded paper near the top post 22. The top post 22 can fully compress the folded paper and press out a groove on the underside of the folded paper. During the test, it was found that after the support force of the rubber buffer layer 12 on the folded paper was weakened, the separation between the top post 22 and the folded paper became unstable. Therefore, the upper end of the top post 22 is processed into an upward-facing frustum shape. The outer diameter value of the top of the top post 22 is still greater than the outer diameter value of the extrusion blade 19, ensuring that the extrusion blade 19 compresses more into the folded paper.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 the present invention should be included within the protection scope of the present invention.
