Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of Kaiselu perfusion, and in particular to a Kaiselu vacuum perfusion device and a preparation process thereof. BACKGROUND

[0002] Kaiselu is a laxative and also a lubricant, and its components are mainly composed of glycerol and other auxiliary drugs; it is suitable for the treatment of children, the elderly and weak constipation patients, and its principle is to use the high concentration of glycerol or sorbitol, that is, the high osmotic effect, to soften the stool and stimulate the intestinal wall to reflexively cause defecation, and in addition, it has a lubricating effect, which can make the stool easily discharged.

[0003] In the prior art, when Kaiselu is filled, vacuum filling treatment is required, and the top end of the Kaiselu bottle needs to be extruded and sealed during filling. However, the Kaiselu bottle is generally a long-necked cylindrical bottle, and its material is polyethylene glycol, which is a plastic material. During extrusion and sealing, two situations generally occur. First, in order to maintain good sealing, the extrusion and sealing force on the top end of the long neck of the bottle is large. Since the material of the bottle is plastic, when the top end of the long neck is subjected to a large extrusion force, the position below the middle of the long neck of the bottle is prone to bending, liquid spills, and the whole bottle is scrapped (bending of the long neck of the bottle affects subsequent use by patients). Second, in order to avoid a large extrusion force, the extrusion and sealing is often poor. Since vacuum filling uses pressure difference for filling, poor sealing results in insufficient pressure difference, which not only leads to a large difference in filling amount of each bottle, but also causes the bottle to be in contact with the outside air for a long time, affecting the subsequent storage quality.

[0004] Therefore, the present application provides a Kaiselu vacuum perfusion device and a preparation process thereof. SUMMARY

[0005] In order to make up for the shortcomings of the prior art and solve the problem of easy bending of the long neck of the bottle and poor sealing, the present application provides a Kaiselu vacuum perfusion device and a preparation process thereof.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A vacuum filling device for glycerin suppositories, comprising a circular plate; an annular block fixedly connected to the bottom end of the circular plate; a cylinder fixedly connected to the side wall of the annular block via a fixing block; a first arc-shaped plate fixedly connected to the top end of the piston rod of the cylinder; a rotating disk provided at the center of the top end of the circular plate; a set of placement grooves opened on the outer circular wall of the rotating disk; a long-necked cylindrical bottle placed in the placement groove; the rotating disk rotating via a rotating component; a set of injection columns fixedly connected to the bottom end of the first arc-shaped plate; a cap sleeve fitted on the outer wall of the injection columns, and the cap sleeve having a convex cross-section; a locking ring fixedly connected to the outer wall of the injection columns; and the inner wall of the top of the cap sleeve... An annular groove is provided on the top; the locking ring is slidably connected in the annular groove; the injection column is syringe-shaped; a set of L-shaped columns are provided on the inner wall of the bottom of the cap, and a support plate is rotatably connected between adjacent L-shaped columns; a positioning rod is fixedly connected to the side wall of the support plate near the top; a first right-angled trapezoidal block is provided on the bottom side wall of the cap relative to the position of the positioning rod; a sealing element is provided on the inner wall of the top of the bottom of the cap; the end of the positioning rod is arc-shaped; during operation, a set of support plates is provided, and the support plates rotate around the L-shaped columns, while the first right-angled trapezoidal block and the positioning rod are provided, allowing the support plates to be in a vertical state after rotation. When not in operation, the set of support plates can be... The top of the bottle is tilted outwards. A long-necked cylindrical bottle is placed in the placement slot. The rotating disc is rotated by a rotating component. After the top of the long-necked cylindrical bottle rotates to directly below the cap tube, the cylinder is activated. The cylinder, through the piston rod, moves the injection column downwards. Simultaneously, the cap tube moves downwards under gravity, first covering the top of the long-necked cylindrical bottle. After the top of the long-necked cylindrical bottle extends into the cap tube, it first contacts the top of the support plate. Then, it is pushed, causing the support plate to rotate vertically. The sealing element inside the cap tube and the long-necked top of the long-necked cylindrical bottle then press and seal against each other. At this point, because the support plate is vertically aligned with the long-necked side of the long-necked cylindrical bottle... The support plate provides structural support, preventing bending and ensuring a tight seal at the top of the long-necked cylindrical bottle. This facilitates subsequent liquid injection via the injection column, guaranteeing the injection volume and preservation quality. The absence of a torsion spring at the hinge of the support plate prevents misalignment caused by torsion spring pressure when the cap moves down to cover the long-necked cylindrical bottle and the support plate comes into contact. The positioning rod and the first right-angled trapezoidal block not only ensure the support plate is in a final vertical fit but also maintain its initial tilted position after the long-necked cylindrical bottle detaches, as the detachment force is downward.

[0007] Preferably, the sealing element includes a circular pressure plate; the circular pressure plate is fixed to the inner wall of the bottom top of the cap cylinder by a spring, and the circular pressure plate covers the central connection of the cap cylinder; a first rubber layer is fixed to the bottom end of the circular pressure plate; during operation, when the cap cylinder moves downward with the injection column, the top of the long-necked cylindrical bottle enters the cap cylinder relative to each other, and then comes into contact with the first rubber layer. At the same time, when the circular pressure plate and the top of the long-necked cylindrical bottle come into contact with each other, the weight of the cap cylinder will continue to compress the spring of the circular pressure plate, thereby pressing the circular pressure plate tightly, so that the first rubber layer and the top opening of the long-necked cylindrical bottle come into close contact with each other, ensuring its sealing effect.

[0008] Preferably, a liquid cavity is provided at the center of the injection column; an annular vacuum cavity is formed within the injection column; the annular vacuum cavity surrounds the liquid cavity; both the annular vacuum cavity and the liquid cavity have syringe-shaped cross-sections; the tips of the injection column, the annular vacuum cavity, and the liquid cavity are conical; the bottom of the conical tip of the liquid cavity and the bottom of the conical tip of the injection column are interconnected through a liquid outlet orifice; the tip of the injection column penetrates the circular pressure plate and the first rubber layer; a set of first through holes are formed on the outer conical wall of the tip of the injection column, and the first through holes are interconnected with the conical cavity at the tip of the annular vacuum cavity; the injection column The outer wall is equipped with a vacuum tube and a liquid injection tube; the liquid injection tube is interconnected with the liquid chamber; the annular vacuum chamber is interconnected with the vacuum tube; a fixing plate is fixed to the side wall of the annular block by a U-shaped rod, and the fixing plate is located above the first arc-shaped plate; a set of sealing rods is fixed to the bottom end of the fixing plate, the sealing rods extend into the liquid chamber, and the bottom end of the sealing rods and the pointed conical inner wall surface of the liquid chamber are in contact with each other; during operation, after the top of the long-necked cylindrical bottle enters the cap cylinder, it will be supported by four sets of support plates, and guided at the same time, so that the middle of the top of the long-necked cylindrical bottle coincides with the center line of the cap cylinder. At the same time, the tip of the liquid injection column is conical and penetrates through... When the first rubber layer is penetrated and the top of the long-necked cylindrical bottle is in contact with it, the tip of the injection column will first enter the long neck opening of the long-necked cylindrical bottle. The conical tip of the injection column ensures smooth entry into the long-necked cylindrical bottle. Then, the entire injection column moves downwards, allowing the conical tip to fully enter the long-necked cylindrical bottle. Simultaneously, the cylindrical surface of the injection column tip will contact the penetration opening of the first rubber layer to form a seal. At this point, the vacuum tube is connected to an external vacuum pump, and the injection tube is connected to an external material tank. Therefore, a vacuum is created through the vacuum tube, and the long-necked cylindrical bottle is evacuated through the annular vacuum chamber and the first through-hole. When a vacuum is drawn inside the flask and the injection column moves downwards, the sealing rod disengages from the tapered tip of the liquid chamber. Under negative pressure, the liquid in the liquid chamber flows out through the outlet orifice, filling the long-necked cylindrical flask in a sealed environment. After filling, the injection column moves upwards, and the sealing rod re-engages with the tapered tip of the liquid chamber to seal the outlet orifice. The viscous nature of the encapsulant prevents the liquid in the outlet orifice from falling under normal pressure, thus not affecting the injection volume or causing overflow.

[0009] Preferably, a set of inverted L-shaped rods are fixed to the outer wall of the injection column; a set of first cavities are provided in the bottom inner wall of the cap cylinder; a second arc-shaped plate is fixed to the inner wall of the cap cylinder by a spring; the ends of the first right-angled trapezoidal block and the L-shaped column are both fixed to the second arc-shaped plate; a second right-angled trapezoidal block is fixed to the side wall of the second arc-shaped plate, and the second right-angled trapezoidal block extends into the first cavity; the bottom end of the inverted L-shaped rod extends into the first cavity; a pair of guide rods are fixed to the side wall of the second arc-shaped plate, and a guide groove is opened on the bottom inner wall of the cap cylinder relative to the position of the guide rod, and the guide rod is slidably connected in the guide groove; during operation, the squeezing force on the long-necked cylindrical bottle originates from the weight of the cap cylinder, but the overall cap cylinder is overloaded. To minimize the impact on installation and subsequent disassembly and cleaning, the system is designed so that after the first rubber layer and the long-necked cylindrical bottle are initially tightly bonded together (at which point the cap's weight applies force to seal), the injection column continues to move downwards. At this point, it moves downwards via an inverted L-shaped rod. When the injection column reaches the rated height, the bottom end of the inverted L-shaped rod first comes into contact with the bottom end of the first cavity, allowing the downward pressure of the injection column to be applied to the cap, thereby increasing the compression sealing effect. Simultaneously, during the process of the inverted L-shaped rod and the bottom end of the first cavity coming into contact, the inverted L-shaped rod first pushes the second right-angled trapezoidal block outwards, thereby causing the support plate to compress and bond the long-necked cylindrical bottle inwards, further ensuring the bonding state and the support strength.

[0010] Preferably, a second cavity is formed in the middle of the first rubber layer; a second through hole is formed at the bottom of the second cavity; the tip of the injection column penetrates the middle of the second cavity, and a set of second through holes is arranged around the tip of the injection column; during operation, with the second cavity, when the long-necked cylindrical bottle and the first rubber layer are attached, the second cavity will be concave, thereby covering the entire long neck end of the long-necked cylindrical bottle and ensuring its sealing effect. At the same time, with the second through hole, the second cavity itself contains a certain amount of air. When the top of the long-necked cylindrical bottle and the first rubber layer are attached, a certain degree of sealing has already been achieved. Then, the circular pressure plate continues to press down, and the second cavity will be forced to concave. The gas in the second cavity will enter the long-necked cylindrical bottle, blowing air into the long-necked cylindrical bottle to expand it and prevent it from having a concave part.

[0011] Preferably, a lower pressure block is slidably connected to the inner wall of the top of the cap cylinder; an annular bladder is fixedly connected between the outer wall of the lower pressure block and the circular pressure plate; a set of third through holes is provided on the annular bladder; a set of fourth through holes is provided on the circular pressure plate; the fourth through holes are interconnected with the second cavity; the tip of the injection column penetrates the middle of the lower pressure block; a set of fourth through holes is arranged around the tip of the injection column; the lower pressure block moves upward by a pulling member; a sealing ring is fixedly connected to the top of the circular pressure plate; during operation, when sealing, the injection column moves downward, which will drive the lower pressure block to move downward through the pulling member, and then the bottom end of the lower pressure block and the sealing ring fit together. The subsequent injection column will compress the sealing ring, sealing the second cavity to facilitate vacuum filling. Because the first rubber layer and the top of the long-necked cylindrical bottle are in contact, and due to the vacuuming process, they will have a certain adsorption force. To release this adsorption force, as the injection column moves upward, the pulling component moves the lower pressure block upward, causing the annular bladder to expand and draw air from the outside through the third through-hole. It then connects to the second cavity through the fourth through-hole. The second cavity, in turn, connects to the top of the long-necked cylindrical bottle through the second through-hole, releasing the vacuum adsorption and facilitating the separation of the cap from the long-necked cylindrical bottle.

[0012] Preferably, the pulling member includes a first groove; a pair of first grooves are provided at the bottom end of the lower pressure block; a pulling rod is provided between the bend of the injection column and the lower pressure block, and one end of the pulling rod extends into the annular vacuum cavity at the bend of the injection column, and the other end passes through the lower pressure block and is located in the first groove. The cross-section of the pulling rod is I-shaped. During operation, the pulling rod is set such that when the injection column moves down, the pulling rod and the circular pressure plate fit together, allowing the lower pressure block to move down and fit together with the sealing ring, thus sealing the fourth through hole. When the inverted L-shaped rod presses down on the cap cylinder, some air in the second cavity will enter the long-necked cylindrical bottle, causing it to expand and preventing the bottle from concave. Excess gas will enter the annular vacuum cavity through the first through hole, without affecting the sealing operation.

[0013] Preferably, the top of the support plate is provided with a second groove; the second groove is rotatably connected to a roller; during operation, when the top of the long-necked cylindrical bottle enters the cap cylinder, it will first come into contact with the top of the support plate, so a roller is provided at the top of the support plate to facilitate the contact and pushing of the two.

[0014] Preferably, the rotating component includes a servo motor; the servo motor is fixedly connected to the bottom end of the circular plate; the output end of the servo motor is provided with a first rotating shaft; the first rotating shaft passes through the circular plate and is fixedly connected to the rotating disk; during operation, the servo motor drives the rotating disk to rotate, which facilitates the adjustment operation.

[0015] A preparation process for vacuum infusion of glycerin suppositories, the process employing the aforementioned vacuum infusion device for glycerin suppositories, the preparation process being as follows:

[0016] S1: Place the long-necked cylindrical bottle into the placement slot of the rotating disk, and then start the servo motor to drive the rotating disk to rotate;

[0017] S2: The piston rod of the cylinder drives the first arc plate to move downward, so that the cap covers the long neck of the long-necked cylindrical bottle. At the same time, the support plate supports and fits the long neck side wall of the long-necked cylindrical bottle, and the sealing element seals the top opening of the long-necked cylindrical bottle.

[0018] S3: The annular vacuum chamber is evacuated through the vacuum tube, and then the long-necked cylindrical bottle is evacuated to a negative pressure state through the first through hole, so that the liquid in the liquid chamber is discharged and filled through the liquid outlet hole. Then, the injection column is moved up by the piston rod of the cylinder, so that the long-necked cylindrical bottle and the cap are separated, thus completing the filling of the long-necked cylindrical bottle.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The vacuum filling device for enema and its preparation process described in this invention, after the sealing element inside the cap and the top of the long neck of the long-necked cylindrical bottle are mutually squeezed and sealed, the support plate is vertically attached to the side wall of the long neck of the long-necked cylindrical bottle, which can play a supporting role and prevent bending. This ensures the sealing effect of the top of the long-necked cylindrical bottle, facilitates the subsequent liquid injection operation through the injection column, and ensures the injection volume and subsequent preservation quality.

[0021] 2. The vacuum filling device for enema and its preparation process described in this invention allow the downward pressure of the injection column to be applied to the cap cylinder, thereby increasing the squeezing and sealing effect. At the same time, during the process of the inverted L-shaped rod and the bottom end of the first cavity fitting together, the inverted L-shaped rod will first push the second right-angled trapezoidal block to move outward, thereby allowing the support plate to squeeze and fit the long-necked cylindrical bottle inward, further ensuring the fitting state and further ensuring the support strength.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 9As shown in the embodiment of the present invention, a vacuum filling device for glycerin suppositories includes a circular plate 1; an annular block 64 is fixedly connected to the bottom end of the circular plate 1; a cylinder 14 is fixedly connected to the side wall of the annular block 64 via a fixing block; a first arc-shaped plate 16 is fixedly connected to the top end of the piston rod 15 of the cylinder 14; a rotating disk 11 is provided at the middle of the top end of the circular plate 1; a set of placement grooves 12 are provided on the outer circular wall of the rotating disk 11; a long-necked cylindrical bottle 13 is placed in the placement groove 12; the rotating disk 11 rotates via a rotating component; a set of injection columns 18 are fixedly connected to the bottom end of the first arc-shaped plate 16; a cap 17 is sleeved on the outer wall of the injection column 18, and the cap 17... 17 has a convex cross-section; a locking ring 21 is fixedly connected to the outer wall of the injection column 18; an annular groove 2 is opened on the inner wall of the top of the cap cylinder 17; the locking ring 21 is slidably connected in the annular groove 2; the injection column 18 is shaped like a syringe; a set of L-shaped columns 22 are provided on the inner wall of the bottom of the cap cylinder 17, and a support plate 23 is rotatably connected between adjacent L-shaped columns 22; a positioning rod 25 is fixedly connected to the side wall of the support plate 23 near the top; a first right-angled trapezoidal block 24 is provided on the bottom side wall of the cap cylinder 17 relative to the position of the positioning rod 25; a sealing element is provided on the inner wall of the bottom top of the cap cylinder 17; the end of the positioning rod 25 is arc-shaped.During operation, a set of support plates 23 are provided, which rotate around the L-shaped column 22. A first right-angled trapezoidal block 24 and a positioning rod 25 are also provided, allowing the support plates 23 to rotate vertically. When not in operation, the top of the support plates 23 is tilted outwards. A long-necked cylindrical bottle 13 is placed in the placement slot 12. The rotating disk 11 is rotated by a rotating component. After the top of the long-necked cylindrical bottle 13 rotates to directly below the cap cylinder 17, the cylinder 14 is activated. The cylinder 14, through the piston rod 15, drives the injection column 18 downwards. Simultaneously, the cap cylinder 17 moves downwards under gravity. The cap cylinder 17 first covers the top of the long-necked cylindrical bottle 13. After the top of the long-necked cylindrical bottle 13 extends into the cap cylinder 17, it first contacts the top of the support plate 23, then pushes it, causing the support plate 23 to rotate vertically. The liquid then flows through the cap cylinder 17... After the sealing element and the top of the long neck of the long-necked cylindrical bottle 13 are pressed and sealed together, the support plate 23 is vertically attached to the side wall of the long neck of the long-necked cylindrical bottle 13, which provides support and prevents bending. This ensures the sealing effect of the top of the long-necked cylindrical bottle 13, facilitating subsequent liquid injection through the injection column 18, ensuring the injection volume and subsequent preservation quality. Furthermore, the absence of a torsion spring at the hinge of the support plate 23 prevents misalignment caused by torsion spring pressure when the top of the long-necked cylindrical bottle 13 contacts the support plate 23 after the cap 17 moves down to cover the long-necked cylindrical bottle 13. The positioning rod 25 and the first right-angled trapezoidal block 24 not only ensure that the support plate 23 is in the final vertically attached state, but also ensure that the support plate 23 remains tilted initially after the long-necked cylindrical bottle 13 is detached, as the detachment force between the cap 17 and the long-necked cylindrical bottle 13 is downward.

[0036] The sealing element includes a circular pressure plate 4; the circular pressure plate 4 is fixed to the inner wall of the bottom top of the cap cylinder 17 by a spring, and the circular pressure plate 4 covers the central connection of the cap cylinder 17; a first rubber layer 41 is fixed to the bottom end of the circular pressure plate 4; during operation, when the cap cylinder 17 moves downward with the injection column 18, the top of the long-necked cylindrical bottle 13 enters the cap cylinder 17 and then comes into contact with the first rubber layer 41. At the same time, when the circular pressure plate 4 and the top of the long neck of the long-necked cylindrical bottle 13 come into contact with each other, the weight of the cap cylinder 17 will continue to compress the spring of the circular pressure plate 4, thereby pressing the circular pressure plate 4 tightly, so that the first rubber layer 41 and the top opening of the long-necked cylindrical bottle 13 come into close contact with each other, ensuring its sealing effect.

[0037] A liquid cavity 3 is provided at the center of the injection column 18; an annular vacuum cavity 31 is formed inside the injection column 18; the annular vacuum cavity 31 surrounds the liquid cavity 3; both the annular vacuum cavity 31 and the liquid cavity 3 have syringe-shaped cross-sections; the tips of the injection column 18, the annular vacuum cavity 31, and the liquid cavity 3 are conical; the bottom end of the conical tip of the liquid cavity 3 and the bottom end of the conical tip of the injection column 18 are interconnected through a liquid outlet fine hole 37; the tip of the injection column 18 penetrates the circular pressure plate 4 and the first rubber layer 41; a set of first through holes 32 are formed on the outer conical outer wall of the tip of the injection column 18, and the first through holes 32 are interconnected with the conical cavity at the tip of the annular vacuum cavity 31; the injection column 18 A vacuum tube 33 and a liquid injection tube 34 are provided on the outer wall; the liquid injection tube 34 is connected to the liquid chamber 3; the annular vacuum chamber 31 is connected to the vacuum tube 33; a fixing plate 36 is fixed to the side wall of the annular block 64 by a U-shaped rod, and the fixing plate 36 is located above the first arc plate 16; a set of sealing rods 35 are fixed to the bottom end of the fixing plate 36, the sealing rods 35 extend into the liquid chamber 3, and the bottom end of the sealing rods 35 and the tip conical inner wall surface of the liquid chamber 3 are in contact with each other; during operation, after the top of the long-necked cylindrical bottle 13 enters the cap cylinder 17, it will be supported by four sets of support plates 23, and guided at the same time, so that the middle of the top of the long-necked cylindrical bottle 13 coincides with the center line of the cap cylinder 17, and at the same time, the tip of the liquid injection column 18 is also aligned. The end is conical and penetrates the first rubber layer 41. When the top of the long-necked cylindrical bottle 13 and the first rubber layer 41 are in contact, the tip of the injection column 18 will first enter the long neck opening of the long-necked cylindrical bottle 13. The conical tip of the injection column 18 ensures that the injection column 18 can smoothly enter the long-necked cylindrical bottle 13. Then the injection column 18 moves downward as a whole, allowing the conical tip of the injection column 18 to completely enter the long-necked cylindrical bottle 13. At the same time, the cylindrical surface of the tip of the injection column 18 will be in contact with the penetration opening of the first rubber layer 41 to form a seal. At this time, the vacuum tube 33 is connected to the external vacuum pump, and the injection tube 34 is connected to the external material box. Therefore, vacuuming is performed through the vacuum tube 33 and through the annular vacuum chamber 31. When the first through-hole 32 evacuates the long-necked cylindrical bottle 13 and the injection column 18 moves downwards, the sealing rod 35 disengages from the tapered tip of the liquid chamber 3. Under negative pressure, the liquid in the liquid chamber 3 flows out through the outlet orifice 37 to fill the long-necked cylindrical bottle 13 in a sealed environment. After filling, the injection column 18 moves upwards. When the injection column 18 moves upwards, the sealing rod 35 re-engages with the tapered tip of the liquid chamber 3 to seal the outlet orifice 37. Since the encapsulant is viscous, the liquid in the outlet orifice 37 is difficult to fall under normal pressure, thus not affecting the injection volume or causing overflow.

[0038] A set of inverted L-shaped rods 53 are fixed to the outer wall of the injection column 18; a set of first cavities 5 are provided in the bottom inner wall of the cap cylinder 17; a second arc-shaped plate 51 is fixed to the inner wall of the cap cylinder 17 by a spring; the ends of the first right-angled trapezoidal block 24 and the L-shaped column 22 are both fixed to the second arc-shaped plate 51; a second right-angled trapezoidal block 52 is fixed to the side wall of the second arc-shaped plate 51, and the second right-angled trapezoidal block 52 extends into the first cavity 5; the bottom end of the inverted L-shaped rod 53 extends into the first cavity 5; a pair of guide rods 54 are fixed to the side wall of the second arc-shaped plate 51, and a guide groove 55 is opened on the bottom inner wall of the cap cylinder 17 at the position relative to the guide rods 54, and the guide rods 54 are slidably connected in the guide groove 55; during operation, the squeezing force on the long-necked cylindrical bottle 13 originates from the weight of the cap cylinder 17, but The excessive weight of the cap 17 affects installation and subsequent disassembly and cleaning. Therefore, after the first rubber layer 41 and the long-necked cylindrical bottle 13 are initially tightly bonded together (at this time, the weight of the cap 17 applies force to seal it), the injection column 18 continues to move downward. At this time, it will move downward through the inverted L-shaped rod 53. When the injection column 18 descends to the rated height, the bottom end of the inverted L-shaped rod 53 will first bond with the bottom end of the first cavity 5, so that the downward pressure of the injection column 18 is applied to the cap 17, thereby increasing the compression sealing effect. At the same time, during the process of the inverted L-shaped rod 53 and the bottom end of the first cavity 5 bonding together, the inverted L-shaped rod 53 will first push the second right-angled trapezoidal block 52 to move outward, thereby causing the support plate 23 to press and bond the long-necked cylindrical bottle 13 inward, further ensuring the bonding state and further ensuring the support strength.

[0039] A second cavity 42 is provided in the middle of the first rubber layer 41; a second through hole 43 is provided at the bottom of the second cavity 42; the tip of the injection column 18 penetrates the middle of the second cavity 42, and a set of second through holes 43 are arranged around the tip of the injection column 18; during operation, the second cavity 42 is provided, and when the long-necked cylindrical bottle 13 and the first rubber layer 41 are attached, the second cavity 42 will be concave, thereby covering the entire long neck end of the long-necked cylindrical bottle 13 to ensure its sealing effect. At the same time, the second through hole 43 is provided, and the second cavity 42 itself contains a certain amount of air. When the top of the long-necked cylindrical bottle 13 is attached to the first rubber layer 41, a certain degree of sealing has already been achieved. Then, the circular pressure plate 4 continues to press down, and the second cavity 42 will be forced to concave. The gas in the second cavity 42 will enter the long-necked cylindrical bottle 13 to blow air into the long-necked cylindrical bottle 13 and prevent it from concave.

[0040] A lower pressure block 44 is slidably connected to the inner wall of the top of the cap cylinder 17; an annular bladder 45 is fixedly connected between the outer wall of the lower pressure block 44 and the circular pressure plate 4; a set of third through holes 46 are opened on the annular bladder 45; a set of fourth through holes 47 are opened on the circular pressure plate 4; the fourth through holes 47 are connected to the second cavity 42; the tip of the injection column 18 penetrates the middle of the lower pressure block 44; a set of fourth through holes 47 are arranged around the tip of the injection column 18; the lower pressure block 44 is moved upward by a pulling member; a sealing ring 471 is fixedly connected to the top of the circular pressure plate 4; during operation, when sealing, the injection column 18 moves downward, which will drive the lower pressure block 44 to move downward through the pulling member, and then the bottom end of the lower pressure block 44 and the sealing ring 471 interact. After the injection column 18 is in place, it will squeeze the sealing ring 471 to seal the second cavity 42, which will facilitate vacuum filling. Then, because the first rubber layer 41 and the top of the long-necked cylindrical bottle 13 are in contact with each other and the vacuuming operation will cause them to have a certain adsorption force. In order to release this adsorption force, when the injection column 18 moves upward, the lower pressure block 44 is moved upward by the pulling component. Then the annular bladder 45 expands and draws air from the outside through the third through hole 46. Then it connects with the second cavity 42 through the fourth through hole 47. The second cavity 42 then connects with the top of the long-necked cylindrical bottle 13 through the second through hole 43, releasing the vacuum adsorption state and facilitating the separation of the cap 17 and the long-necked cylindrical bottle 13.

[0041] The pulling component includes a first groove 48; a pair of first grooves 48 are provided at the bottom end of the lower pressure block 44; a pulling rod 49 is provided between the bend of the injection column 18 and the lower pressure block 44, and one end of the pulling rod 49 extends into the annular vacuum cavity 31 at the bend of the injection column 18, and the other end passes through the lower pressure block 44 and is located in the first groove 48. The cross-section of the pulling rod 49 is I-shaped. During operation, the pulling rod 49 is set so that when the injection column 18 moves down, the pulling rod 49 and the circular pressure plate 4 fit together, allowing the lower pressure block 44 to move down and fit together with the sealing ring 471, thus sealing the fourth through hole 47. When the inverted L-shaped rod 53 presses down on the cap cylinder 17, some air in the second cavity 42 will enter the long-necked cylindrical bottle 13 to expand it, preventing the bottle from collapsing. Excess gas will enter the annular vacuum cavity 31 through the first through hole 32 without affecting the sealing operation.

[0042] The top of the support plate 23 is provided with a second groove 6; the second groove 6 is rotatably connected to a roller 61; during operation, when the top of the long-necked cylindrical bottle 13 enters the cap cylinder 17, it will first come into contact with the top of the support plate 23, so the roller 61 is provided at the top of the support plate 23 to facilitate the contact and pushing of the two.

[0043] The rotating component includes a servo motor 62; the bottom end of the circular plate 1 is fixedly connected to the servo motor 62; the output end of the servo motor 62 is provided with a first rotating shaft 63; the first rotating shaft 63 passes through the circular plate 1 and is fixedly connected to the rotating disk 11; during operation, the servo motor 62 drives the rotating disk 11 to rotate, which facilitates the adjustment operation.

[0044] Working principle: A set of support plates 23 are provided, which rotate around the L-shaped column 22. A first right-angled trapezoidal block 24 and a positioning rod 25 are also provided, allowing the support plates 23 to rotate vertically. When not in operation, the top of the set of support plates 23 is tilted outwards. A long-necked cylindrical bottle 13 is placed in the placement slot 12. The rotating disk 11 is rotated by a rotating component. After the top of the long-necked cylindrical bottle 13 rotates to directly below the cap cylinder 17, the cylinder 14 is activated. The cylinder 14, through the piston rod 15, drives the injection column 18 downwards. Simultaneously, the cap cylinder 17 moves downwards under gravity. Upon movement, the cap 17 first covers the top of the long-necked cylindrical bottle 13. After the top of the long-necked cylindrical bottle 13 extends into the cap 17, it first contacts the top of the support plate 23. Then, it is pushed to rotate the support plate 23 into a vertical position. After the sealing element inside the cap 17 and the top of the long-necked cylindrical bottle 13 are pressed and sealed, the support plate 23, being vertically attached to the side wall of the long neck of the long-necked cylindrical bottle 13, provides support and prevents bending, ensuring the sealing effect of the top of the long-necked cylindrical bottle 13. This facilitates subsequent liquid injection through the injection column 18, ensuring the injection volume and subsequent preservation quality, while also providing support. No torsion spring is provided at the hinge of plate 23 to avoid misalignment caused by torsion spring compression when the top of the long-necked cylindrical bottle 13 comes into contact with the support plate 23 when the cap 17 moves down to cover the long-necked cylindrical bottle 13. The positioning rod 25 and the first right-angled trapezoidal block 24 not only ensure that the support plate 23 is in the final vertical fit, but also ensure that the support plate 23 is in the initial tilted state after the long-necked cylindrical bottle 13 is detached, since the detachment force between the cap 17 and the long-necked cylindrical bottle 13 is set downwards. After the top of the long-necked cylindrical bottle 13 enters the cap 17, it will be supported by four sets of support plates 23, and simultaneously guided. The top center of the long-necked cylindrical bottle 13 is aligned with the center line of the cap 17. At the same time, the tip of the injection column 18 is conical and penetrates the first rubber layer 41. When the top of the long-necked cylindrical bottle 13 and the first rubber layer 41 are in contact with each other, the tip of the injection column 18 will first enter the long neck opening of the long-necked cylindrical bottle 13. The conical tip of the injection column 18 can ensure that the injection column 18 can smoothly enter the long-necked cylindrical bottle 13. Then the injection column 18 moves down as a whole, so that the conical tip of the injection column 18 is completely inserted into the long-necked cylindrical bottle 13. At the same time, the cylindrical surface of the tip of the injection column 18 will be in contact with the penetration of the first rubber layer 41 to form a seal.At this time, the vacuum tube 33 is connected to the external vacuum pump, and the liquid injection tube 34 is connected to the external material box. Therefore, vacuuming is performed through the vacuum tube 33, and the long-necked cylindrical bottle 13 is evacuated through the annular vacuum chamber 31 and the first through hole 32. At the same time, when the liquid injection column 18 moves downward, the sealing rod 35 disengages from the tapered tip of the liquid chamber 3. Under negative pressure, the liquid in the liquid chamber 3 will be filled through the liquid outlet 37, thus filling the long-necked cylindrical bottle 13 in a sealed environment. After filling, the liquid injection column 18 will move upward. When the liquid injection column 18 moves upward, the sealing rod 35 will re-engage with the tapered tip of the liquid chamber 3 to seal the liquid outlet 37. At the same time, the encapsulant is viscous, and the liquid in the liquid outlet 37 is difficult to fall under normal pressure, so it will not affect the liquid injection volume or cause any problems. In the event of overflow, the squeezing force on the long-necked cylindrical bottle 13 originates from the weight of the cap 17. However, the excessive weight of the cap 17 affects installation and subsequent disassembly and cleaning. Therefore, after the first rubber layer 41 and the long-necked cylindrical bottle 13 are initially tightly bonded (at this point, the weight of the cap 17 applies force to seal it), the injection column 18 continues to move downward. At this time, it moves downward through the inverted L-shaped rod 53. When the injection column 18 descends to the rated height, the bottom end of the inverted L-shaped rod 53 first bonds with the bottom end of the first cavity 5, allowing the downward pressure of the injection column 18 to be applied to the cap 17, thereby increasing the squeezing and sealing effect. Simultaneously, during the process of the inverted L-shaped rod 53 bonding with the bottom end of the first cavity 5, the inverted L-shaped rod 53 first pushes the second right-angled trapezoidal block 52 outward, thereby allowing the support plate 23 to squeeze and bond the long-necked cylindrical bottle 13 inward, further ensuring the bonding state and further ensuring the support strength.

[0045] like Figure 10 As shown, a preparation process for vacuum infusion of glycerin suppositories is described. This process uses the aforementioned vacuum infusion device for glycerin suppositories, and the preparation process is as follows:

[0046] S1: Place the long-necked cylindrical bottle 13 into the placement slot 12 of the rotating disk 11, and then start the servo motor 62 to drive the rotating disk 11 to rotate;

[0047] S2: The piston rod 15 of the cylinder 14 drives the first arc plate 16 to move downward, so that the cap 17 covers the long neck of the long-necked cylindrical bottle 13. At the same time, the support plate 23 supports and fits the long neck side wall of the long-necked cylindrical bottle 13, and the sealing element seals the top opening of the long-necked cylindrical bottle 13.

[0048] S3: Vacuum the annular vacuum chamber 31 through the vacuum tube 33, and then create a negative pressure state for the long-necked cylindrical bottle 13 through the first through hole 32, so that the liquid in the liquid chamber 3 can be discharged and filled through the liquid outlet 37. Then, the injection column 18 is moved upward by the piston rod 15 of the cylinder 14, so that the long-necked cylindrical bottle 13 and the cap 17 are separated from each other, and the filling of the long-necked cylindrical bottle 13 is completed.
