Description

Technical Field

[0001] The invention belongs to the technical field of disinfection tablets, and specifically relates to a forming device for effervescent disinfection tablets. Background Art

[0002] Effervescent disinfection tablets are often provided in the form of round tablets for easy storage, transportation and packaging. Block effervescent disinfection tablets are obtained by extruding powder. During extrusion, the raw material powder is filled into the lower punch head, and then the upper punch head is used to align the lower punch head for extrusion, so that the powder is agglomerated in a small space.

[0003] When filling powder, because the raw material is in powder form and the powder falls into the lower punch head under the action of gravity or scraper, there are often gaps between the powders. The filling space in the lower punch head remains unchanged, and the gaps between the powders after filling are inconsistent. There may even be bubbles between the powders locally, resulting in unstable weight of the filled powder.

[0004] Due to the unstable weight of the filling material, the weight of the tablets after compression molding is inconsistent, which causes the effective composition of a single tablet to fluctuate and increases the instability of product quality. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a forming device for effervescent disinfectant tablets, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: the present invention proposes a forming device for effervescent disinfection tablets, comprising a lower opening convex disc, the lower opening convex disc is fixed and cannot rotate, and the lower opening convex disc is an unclosed notched ring.

[0007] Furthermore, a first turntable is rotatably provided above the lower opening convex disc, and a lower punch die head capable of sliding up and down is provided in a circular array on the first turntable.

[0008] Furthermore, in order to control the up and down position of the lower punch die head, a lower protrusion is provided on the upper wall of the lower opening convex disc.

[0009] Furthermore, a second turntable is provided above the first turntable, and an upper punch die head capable of sliding up and down is provided in a circular array on the second turntable, and the upper punch die head is arranged opposite to the lower punch die head.

[0010] Furthermore, a top convex disc is provided above the second turntable, and the top convex disc cannot rotate. The upper end of the upper punch die head is in sliding contact with the lower wall of the top convex disc. In order to move the upper punch die head up and down, an upper protrusion is provided on the lower wall of the top convex disc.

[0011] Furthermore, in order to enable the upper punch die head and the lower punch die head to move up or down at the same time, the protrusion position of the upper protrusion is the same as that of the lower protrusion.

[0012] Furthermore, in order to make the first turntable and the second turntable rotate synchronously and ensure the synchronous rotation of the upper punch die head and the lower punch die head that cooperate with each other, a first motor is provided on the top boss, and the output shaft of the first motor is respectively connected to the center key of the first turntable and the second turntable.

[0013] Furthermore, a vibration ladder block is embedded in the notch of the lower opening convex disc, and the vibration ladder block can slide up and down relative to the lower opening convex disc to achieve reciprocating vibration.

[0014] Furthermore, a feeding hopper is connected to the outer side of the first turntable, and the feeding hopper and the vibrating ladder block are adapted to each other at an angle relative to the first turntable in the horizontal direction. The lower end of the lower punch head is in sliding contact with the lower opening convex plate and the annular upper wall surrounded by the vibrating ladder block.

[0015] Furthermore, in order to make the vibrating ladder block vibrate reciprocatingly, a pad is provided under the vibrating ladder block, the pad is fixed, a second spring is connected between the pad and the vibrating ladder block, a second motor is fixed on the outside of the pad, a cam is provided on the output shaft of the second motor, and the cam cooperates with the vibrating ladder block.

[0016] Furthermore, a flange is provided in the middle of the upper punch die head, a pressure head is provided at the lower end of the flange, the pressure head is adapted to the inner cavity of the lower punch die head, a first spring is connected between the flange and the lower wall of the first turntable, and the first spring always connects the upper punch die head upward.

[0017] Furthermore, in order to separate the tablets formed by the compression block from the inner cavity of the lower punch die head, a slide groove is provided on the side wall of the inner cavity of the lower punch die head, a discharge core rod is slidably provided in the lower punch die head, and a side plate is provided on the outer wall of the discharge core rod, and the side plate is slidably provided in the slide groove, and a third spring is connected between the discharge core rod and the lower punch die head. When the side plate moves to the top of the slide groove, the discharge core rod is flush with the upper wall of the lower punch die head.

[0018] Furthermore, in order to separate the tablets from the first turntable so as to package the tablets, a discharge slope is provided on the first turntable, and a discharge baffle is provided on the discharge slope, and the discharge baffle is arranged on the outer side of the intersection line between the first turntable and the lower protrusion.

When the first turntable continues to rotate, it will drive the tablets to move, and the tablets are intercepted by the discharge baffle and separated along the discharge slope.

[0019] The beneficial effects achieved by the present invention are as follows: 1. The vibrating ladder block can reciprocate under the action of the cam, thereby driving the lower punch die head to reciprocate, making the material in the lower punch die head more compact, promoting the separation of bubbles in the powder in the lower punch die head, reducing the weight difference between tablets, and the gradually decreasing step shape can reduce the vibration amplitude of the lower punch die head and prevent the internal powder raw materials from splashing; 2. The vibration ladder block is in the shape of a gradually lowered ladder. While it drives the lower punch head to vibrate back and forth, it can also ensure that the highest point of the vibration ladder block is always no higher than the highest point of the gap of the lower opening convex disc, and the lowest point of the vibration ladder block is always no lower than the lowest point of the gap of the lower opening convex disc, ensuring that the lower punch head can slide smoothly between the lower opening convex disc and the vibration ladder block.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0025] like Figure 1 and Figure 2 As shown, an effervescent disinfection tablet forming device provided in an embodiment of the present invention comprises a lower opening convex disc 1, the lower opening convex disc 1 is fixed and cannot rotate, and the lower opening convex disc 1 is an unclosed notched ring.

[0026] A first turntable 2 is rotatably provided above the lower opening convex disc 1, and a lower punch head 8 that can slide up and down is provided in a circular array on the first turntable 2. The inner cavity of the lower punch head 8 is used to fill the raw material powder. When the lower punch head 8 rotates with the first turntable 2, it can also move up and down as needed. When the lower punch head 8 moves up, the lower punch head 8 is at the working point of extrusion molding.

[0027] In order to control the upper and lower positions of the lower punch head 8, a lower protrusion 13 is provided on the upper wall of the lower opening convex disc 1. The lower protrusion 13 is arranged near the notch of the lower opening convex disc 1, and is in an arc rising state at the notch. After rising to a set height, it is in a horizontal state, and then presents a state of arc descending.

[0028] A second turntable 3 is provided above the first turntable 2. The second turntable 3 rotates synchronously with the first turntable 2. An upper punch die head 7 which can slide up and down is provided in a circular array on the second turntable 3. The upper punch die head 7 and the lower punch die head 8 are arranged opposite to each other, that is, there is a lower punch die head 8 under each upper punch die head 7. When the upper punch die head 7 moves toward the lower punch die head 8, the material inside the lower punch die head 8 can be squeezed into blocks.

[0029] A top convex plate 4 is provided above the second turntable 3. The top convex plate 4 cannot rotate and is fixed by a bracket (not shown in the accompanying drawings). The upper end of the upper punch die 7 is in sliding contact with the lower wall of the top convex plate 4. In order to enable the upper punch die 7 to move up and down, an upper protrusion 14 is provided on the lower wall of the top convex plate 4. When the upper punch die 7 moves to the upper protrusion 14, the upper punch die 7 will move up and down along the slope of the upper protrusion 14, thereby changing the position of the upper punch die 7. When the upper punch die 7 moves to the lowest point, the upper punch die 7 is in the extrusion working point.

[0030] In order to make the upper punch die 7 and the lower punch die 8 move up or down at the same time, the upper protrusion 14 and the lower protrusion 13 have the same protrusion position.

[0031] In order to make the first turntable 2 and the second turntable 3 rotate synchronously and ensure the synchronous rotation of the upper punch die head 7 and the lower punch die head 8 that cooperate with each other, a first motor 5 is provided on the top convex plate 4, and the output shaft of the first motor 5 is respectively connected to the center keys of the first turntable 2 and the second turntable 3. When the first motor 5 rotates, it will drive the first turntable 2 and the second turntable 3 to rotate at the same time, so that the upper punch die head 7 and the lower punch die head 8 that are opposite to each other rotate synchronously.

[0032] like Figure 4 As shown, a vibration ladder block 6 is embedded in the notch of the lower opening convex disc 1. The vibration ladder block 6 is a multi-level step-like arc block. The vibration ladder block 6 can slide up and down relative to the lower opening convex disc 1 to achieve reciprocating vibration, and the highest point of the vibration ladder block 6 is always not higher than the highest point of the notch of the lower opening convex disc 1, and the lowest point of the vibration ladder block 6 is always not lower than the lowest point of the notch of the lower opening convex disc 1, so as to ensure that the lower punch head 8 can slide smoothly between the lower opening convex disc 1 and the vibration ladder block 6.

[0033] like Figure 3 As shown, a feeding hopper 10 is connected to the outer side of the first turntable 2, and the feeding hopper 10 and the vibrating ladder block 6 are adapted to the angle of the first turntable 2 in the horizontal direction. The powder raw material in the feeding hopper 10 falls to the upper wall of the first turntable 2 under the action of gravity, and the dropping area here also coincides with the area where the vibrating ladder block 6 is located. The lower end of the lower punch head 8 is in sliding contact with the lower opening convex plate 1 and the annular upper wall surrounded by the vibrating ladder block 6. When the lower punch head 8 moves to different positions, the height of each lower punch head 8 relative to the first turntable 2 is also different. The height of the lower punch head 8 in the area where the vibrating ladder block 6 is located is the lowest, so as to facilitate the powder material to fall from the upper wall of the first turntable 2 into the lower punch head 8, and the height of the lower punch head 8 at the lower convex block 13 is the highest, so that the lower punch head 8 and the upper punch head 7 can be squeezed and matched with each other to compact the powder into blocks.

[0034] like Figure 5As shown, in order to make the vibrating ladder block 6 vibrate back and forth, a pad 16 is provided under the vibrating ladder block 6, and the pad 16 is fixed. A second spring 17 is connected between the pad 16 and the vibrating ladder block 6, and a second motor 18 is fixed on the outside of the pad 16. A cam 19 is provided on the output shaft of the second motor 18, and the cam 19 cooperates with the vibrating ladder block 6. When the second motor 18 is started, the cam 19 is driven to rotate, and the cam 19 overcomes the pulling force of the second spring 17 to push the vibrating ladder block 6 upward for reciprocating motion, so that the lower punch head 8 in contact with the vibrating ladder block 6 vibrates back and forth, and the powder raw material in the lower punch head 8 vibrates at a high frequency, and the gaps or bubbles in the powder are discharged, so that the powder is more compact and dense, and the weight stability of each disinfection tablet is improved.

[0035] like Figure 6-Figure 8 As shown, a flange 23 is provided in the middle of the upper punch head 7, and a pressure head 24 is provided at the lower end of the flange 23. The pressure head 24 is adapted to the inner cavity of the lower punch head 8 so that the pressure head 24 can enter the inner cavity of the lower punch head 8 to press the powder. A first spring 9 is connected between the flange 23 and the lower wall of the first turntable 2. The first spring 9 always connects the upper punch head 7 upward. When the upper punch head 7 moves to the outer area of ​​the upper protrusion 14, the upper punch head 7 is pulled to the highest point by the first spring 9 and separated from the lower punch head 8. When the upper punch head 7 moves to the upper protrusion 14 area, the upper punch head 7 compresses the first spring 9 under the action of the upper protrusion 14 and moves downward.

[0036] In order to separate the tablets formed by the compression block from the inner cavity of the lower punch die 8, a slide groove 21 is provided on the side wall of the inner cavity of the lower punch die 8, a discharge core rod 15 is slidably provided in the lower punch die 8, and a side plate 22 is provided on the outer wall of the discharge core rod 15. There is a drop between the side plate 22 and the top of the discharge core rod 15, and the side plate 22 is slidably provided in the slide groove 21. A third spring 20 is connected between the discharge core rod 15 and the lower punch die 8. When the side plate 22 moves to the top of the slide groove 21, the discharge core rod 15 is flush with the upper wall of the lower punch die 8, and when the pressure head 24 is pressed into the inner cavity of the lower punch die 8, the side plate 22 moves to the bottom end of the slide groove 21.

[0037] like Figure 3As shown, in order to separate the tablets from the first turntable 2 for tablet packaging, the first turntable 2 is provided with a discharge slope 12, and the discharge slope 12 is provided with a discharge baffle 11, and the discharge baffle 11 is arranged on the outer side of the intersection line of the first turntable 2 and the lower protrusion 13. When the lower punch head 8 moves to the outer side of the intersection line of the first turntable 2 and the upper protrusion 14, the lower punch head 8 is no longer pushed upward by the lower protrusion 13, and the upper punch head 7 is no longer pushed downward by the upper protrusion 14. The lower punch head 8 and the upper punch head 7 are separated from each other, and the pressure head 24 is pulled out from the inner cavity of the lower punch head 8. The discharge core rod 15 is pushed upward under the action of the third spring 20, thereby ejecting the pressed tablets to the outside of the top of the lower punch head 8. When the first turntable 2 continues to rotate, it will drive the tablets to move, and the tablets are intercepted by the discharge baffle 11 and separated along the discharge slope 12.

[0038] When in use, the powder raw material is poured into the feeding hopper 10, and the first motor 5 and the second motor 18 are started. The first motor 5 drives the first turntable 2 and the second turntable 3 to rotate, and the first turntable 2 and the second turntable 3 respectively drive the lower punch head 8 and the upper punch head 7 to rotate.

[0039] When the lower punch die head 8 rotates to the area of ​​the vibrating ladder block 6, due to the height difference of the vibrating ladder block 6, the lower punch die head 8 slides downward relative to the first turntable 2. At this time, the powder raw material can fall into the opening at the upper end of the lower punch die head 8 to complete the loading operation. While the lower punch die head 8 continues to rotate, the second motor 18 drives the vibrating ladder block 6 to vibrate at high frequency through the cam 19, so that the lower punch die head 8 on the vibrating ladder block 6 vibrates synchronously with high frequency. When the lower punch die head 8 vibrates, the gaps or bubbles between the powder in the groove can be eliminated, thereby making the powder in the groove more compact, reducing the weight error during loading, and improving the uniformity of each tablet.

[0040] When the lower punch head 8 follows the first turntable 2 to rotate out of the area where the vibrating ladder block 6 is located, the lower punch head 8 will move upward along the lower protrusion 13. At this time, the upper punch head 7 will overcome the resistance of the first spring 9 and move downward along the upper protrusion 14 until the pressure head 24 is completely embedded in the inner cavity of the lower punch head 8.

[0041] The pressing head 24 overcomes the resistance of the discharge core rod 15 and the third spring 20 and presses the powder into blocks. When the upper punch die 7 and the lower punch die 8 rotate to the outer areas of the upper protrusion 14 and the lower protrusion 13 respectively, the upper punch die 7 moves upward to the highest point under the action of the first spring 9, and the lower punch die 8 falls downward to the lowest point under the action of gravity. After the two are separated, the discharge core rod 15 is no longer subjected to pressure and is pushed upward under the action of the third spring 20 to eject the pressed tablets.

[0042] The tablets move along with the first rotating disk 2 until they come into contact with the discharge baffle 11. Under the action of friction, the tablets move along the discharge baffle 11 to the discharge slope 12 and are separated out under the action of gravity.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
