Description

Technical Field

[0001] The utility model relates to the technical field of injection nozzles, in particular to a novel soft capsule injection nozzle. Background Art

[0002] In the production of soft capsules, it is generally completed by the extrusion of the mold and the work of the liquid injection device. For example, the application document with application number CN202322413120.1 in the patent library discloses a preparation mold for soft capsule production. By pressing down the electric push rod, the top plate drives the dispensing pipe to move in a directional manner in the reset groove, and then the dispensing nozzle is placed above the glued soft capsule rubber skin for liquid injection. However, there are still certain problems when using it:

[0003] 1) The feeding component used for liquid injection distributes liquid medicine to several feeding nozzles through a distributing pipe, which results in uneven distribution of liquid medicine near the distributing pipe feeding end and the distributing pipe feeding end far away from the distributing pipe feeding end per unit time;

[0004] 2) Several feeding nozzles are fed through a feeding pipe. Once one of the feeding nozzles has a problem, the soft capsule at the corresponding position will not be able to successfully complete the injection of the drug solution. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a novel soft capsule injection nozzle.

[0006] The technical solution of this utility model is as follows:

[0007] A novel soft capsule injection nozzle comprises a spray body and an injection device arranged at its lower side. The spray body can be arranged above two rollers used for soft capsule molding, and the injection of liquid medicine is completed through the injection device.

[0008] As the core technical concept of the utility model, the spray body includes a transversely arranged strip-shaped main body, the injection device includes a mounting plate transversely arranged on the lower side of the main body, and a driving machine which is transmission-connected to the mounting plate and can drive the mounting plate to slide back and forth along the length direction of the main body, a liquid storage chamber is also provided inside the main body, the injection device also includes a plurality of injection pipes which are arranged on the lower side of the mounting plate and are linearly arranged along the length direction of the main body, an injection pump corresponding to the plurality of injection pipes is also provided on the upper side of the mounting plate, and the injection pump is connected to the liquid storage chamber and the injection pipe. On the basis of the above structure, The operation of the injection nozzle (a new type of soft capsule injection nozzle mentioned above) cooperates with the two rollers used for soft capsule molding to complete the injection molding of the soft capsule, and each injection tube corresponds to a separate injection pump, which ensures the uniformity of the injection of soft capsules corresponding to the positions of several injection tubes within a unit time. At the same time, if a single injection tube is blocked, or a single group of injection units (injection tubes and injection pumps) fails, the driving machine drives the mounting plate to slide back and forth to complete the injection of the soft capsules at the damaged position of the injection unit, thereby ultimately ensuring that the molding of the soft capsules can be successfully completed.

[0009] As described above, a new type of soft capsule injection nozzle, specifically speaking, with regard to the installation method of the injection device, a mounting groove running through both ends of the main body is opened in the middle of the lower side, a slot is provided on the side wall of the mounting groove, and the mounting plate is slidably inserted into the slot from one end of the mounting groove, so that the disassembly and assembly connection work between the injection device and the spray body can be simpler and more convenient.

[0010] Specifically speaking of the driving method of the driving machine, a notch that is connected to the mounting groove is provided on one side of the main body, and the driving machine includes a motor arranged in the notch, and a driving wheel that is rollingly engaged with the side of the mounting plate is also provided at its transmission end. The driving machine is hidden in the notch on one side of the main body to prevent it from being contaminated by the drug liquid, thereby ensuring its service life and saving installation space.

[0011] As a preferred embodiment, the liquid storage chambers are relatively provided with two, and the two adjacent injection pumps are respectively connected to the two liquid storage chambers. Both liquid storage chambers can complete the injection work of the soft capsule through the injection pumps to ensure that the liquid medicine can be adequately supplied. At the same time, once the liquid medicine is scarce in one of the liquid storage chambers, the injection work of the soft capsule can still be completed normally through the action of the other liquid storage chamber cooperating with the driving stage.

[0012] In order to facilitate the connection between the injection pump and the liquid storage chamber, an operation port penetrating into the installation groove is also vertically provided on the upper part of the main body, and the two liquid storage chambers are arranged on both sides of the operation port.

[0013] In order to prevent the reciprocating movement of the injection pump from affecting the connection between the injection pump and the liquid storage chamber, the injection pump is connected to the liquid storage chamber through a connecting hose.

[0014] As described above, a novel soft capsule injection nozzle is provided, in order to ensure that when one group of injection units fails, the adjacent group of injection units can be smoothly replaced to complete the injection work, the mounting plate is set to a minimum distance that can be reciprocated under the drive of a driving motor, which is not less than the spacing between two adjacent injection tubes.

[0015] In order to ensure the service life of the injection tube and prevent the contamination of the liquid medicine, the injection tube is made of stainless steel.

[0016] The beneficial effects of the utility model are as follows: the utility model is a novel soft capsule injection nozzle, which can complete the injection and molding of the soft capsule by working the injection nozzle and cooperating with two rollers used for the soft capsule molding work, and each injection tube corresponds to a setting mode of an injection pump separately, thereby ensuring the injection uniformity of the soft capsules corresponding to the positions of several injection tubes within a unit time, and at the same time, if a single injection tube is blocked or a single group of injection units fails, the driving machine drives the mounting plate to slide back and forth to complete the injection of the soft capsules at the damaged position of the injection unit, thereby finally ensuring that the molding of the soft capsule can be completed smoothly.

[0024] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0025] Embodiment: This embodiment provides a new soft capsule injection nozzle, see Figure 1, including a spray body 1 and a liquid injection device 2 arranged at its lower side. The spray body 1 can be arranged above two rollers used for soft capsule molding, and the injection of the liquid medicine is completed through the liquid injection device 2. The structure of the liquid injection nozzle (the above-mentioned new type of soft capsule liquid injection nozzle) is described in detail below.

[0026] In this embodiment, the spray body 1 includes a transversely arranged strip-shaped main body 11, whose cross section is an inverted triangle, and whose lower two sides are arc-shaped structures with openings facing outward and downward, so that it can better cooperate with two rollers used for soft capsule molding.

[0027] In this embodiment, as the core technical concept of the utility model, the injection device 2 includes a mounting plate 21 arranged transversely on the lower side of the main body 11, and a driving machine 25 which is transmission-connected to the mounting plate 21 and can drive the mounting plate 21 to slide back and forth along the length direction of the main body 11. A liquid storage chamber 12 is also provided inside the main body 11. The injection device 2 also includes a plurality of injection tubes 23 arranged linearly along the length direction of the main body 11 and arranged on the lower side of the mounting plate 21. An injection pump 22 corresponding to the plurality of injection tubes 23 is also provided on the upper side of the mounting plate 21, and the injection pump 22 is connected to the liquid storage chamber 12 and the injection tube 23. On the basis of the above structure, the liquid injection nozzle works in cooperation with two rollers for soft capsule molding to complete the liquid injection molding of the soft capsule, and each liquid injection tube 23 corresponds to a liquid injection pump 22 separately, which ensures the uniformity of the liquid injection of the soft capsules corresponding to the positions of several liquid injection tubes 23 per unit time. At the same time, if a single liquid injection tube 23 is blocked, or a single group of liquid injection units (liquid injection tubes 23 and liquid injection pumps 22) fails, the driving machine 25 drives the mounting plate 21 to slide back and forth to complete the liquid injection of the soft capsule at the damaged position of the liquid injection unit, thereby finally ensuring that the molding of the soft capsule can be successfully completed.

[0028] To ensure that when one group of injection units fails, the adjacent group of injection units can be successfully replaced to complete the injection work, the mounting plate 21 is set to a minimum distance that can be reciprocated under the drive of the driving machine 25, which is not less than the distance between two adjacent injection pipes 23.

[0029] In order to ensure the service life of the injection tube 23 and prevent the contamination of the liquid medicine, the injection tube 23 is made of stainless steel.

[0030] Specifically speaking, as to the matching structure between the injection device 2 and the main body 11, a through-hole 13 is vertically opened in the middle of the spray body 1, which passes through the upper and lower parts. The through-hole 13 includes a mounting groove located in the middle of the lower side of the main body 11 and passing through both ends of the main body 11. Slots are opened on the two opposite side walls of the mounting groove along the length direction of the main body 11. The mounting plate 21 is a strip-like structure, which is horizontally slidably inserted into the slot from one end of the self-mounting groove, so that the disassembly and assembly connection work between the injection device 2 and the spray body 1 can be simpler and more convenient.

[0031] On the basis of the connection structure between the above-mentioned mounting plate 21 and the main body 11, a notch which is connected with the mounting groove is also horizontally opened on one side of the main body 11. The driving motor 25 includes a motor arranged in the notch, and a driving wheel which is rollingly fitted with the side of the mounting plate 21 is also provided at its transmission end. The driving wheel is driven to rotate by the driving motor 25, so as to complete the reciprocating drive movement of the mounting plate 21. The driving motor 25 is hidden in the notch on one side of the main body 11 to prevent it from being contaminated by the liquid medicine, thereby ensuring its service life and effectively saving the installation space of the driving motor 25.

[0032] In the present embodiment, as a preferred implementation, the liquid storage chamber 12 is relatively provided with two, and the two adjacent injection pumps 22 are respectively connected to the two liquid storage chambers 12, that is, a plurality of the liquid discharge pumps are staggered and respectively connected to the two liquid storage chambers 12, so that the two liquid storage chambers 12 can complete the injection work of the soft capsule through the injection pump 22, ensuring that the liquid medicine can be adequately supplied. At the same time, once the liquid medicine in one of the liquid storage chambers 12 is scarce, the injection work of the soft capsule can still be completed normally through the action of the other liquid storage chamber 12 cooperating with the driving stage.

[0033] Furthermore, in order to prevent the injection pump 22 from affecting the communication relationship with the liquid storage chamber 12 due to the reciprocating movement, the injection pump 22 is connected to the liquid storage chamber 12 through a connecting hose 24.

[0034] As a further preferred embodiment, the through-port 13 also includes an operating port vertically arranged on the upper part of the main body 11 and extending from the upper side of the main body 11 to the mounting groove. The connecting hose 24 is located in the operating port, and its two ends are respectively connected to the liquid storage chamber 12 and the injection pump 22. The two liquid storage chambers 12 are arranged on both sides of the operating port, so that the connection between the injection pump 22 and the liquid storage chamber 12 and the observation of the connection status can be more convenient.
