Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine eye patch injection technology, and specifically relates to an injection device and process for the production of traditional Chinese medicine eye patches with equal-volume feeding. Background Technology

[0002] The traditional Chinese medicine eye patch injection device typically consists of an equal volume injection system, injection pipes, and injection nozzles. During the use of the traditional Chinese medicine eye patch injection device, the mold for forming the eye patch is first placed under the injection nozzle, and several forming holes on the mold are aligned with the adjacent injection nozzles. Then, several equal amounts of medicine are injected into different forming holes simultaneously through several injection nozzles. After the medicine cools and solidifies, it is removed, collected, and packaged.

[0003] There are many types of medicinal liquids used in the production of traditional Chinese medicine eye patches, including highly viscous hydrogel liquids. Although hydrogel liquids can be quickly formed in the mold, thereby improving the efficiency of the production of traditional Chinese medicine eye patches, due to the extremely high viscosity of the gel and the small diameter of the injection nozzle used in the production of traditional Chinese medicine eye patches, the hydrogel liquid is prone to dripping onto the injection nozzle and cannot fall into the corresponding forming hole in time. This results in a reduction in the amount of hydrogel liquid entering the forming hole of the mold, which leads to differences in the amount of liquid in each forming hole after equal feeding, thus affecting the quality of the formed eye patch. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides an injection device and process for the production of equal-volume feeding type Chinese medicine eye patches.

[0005] The technical solution is as follows: A liquid injection device for producing traditional Chinese medicine eye patches with equal-volume feeding, comprising a worktable, wherein the worktable is provided with symmetrically distributed first electromagnetic slide rails, and first electromagnetic sliders are slidably connected to the first electromagnetic slide rails of the worktable. The symmetrically distributed first electromagnetic sliders are jointly fixed to a support frame, and a linear array of fixed blocks is fixedly connected to the lower part of the support frame. A linear array of liquid injection pipes is fixedly connected to the support frame, and the liquid injection pipes are connected to a medicine liquid pumping device. The liquid injection pipes pass through adjacent fixed blocks. A hollow shell is rotatably connected to an adjacent injection pipe. The hollow shell is connected to the adjacent injection pipe, and a sleeve is fixedly connected to the lower side of the hollow shell. A frustum block is slidably connected inside the hollow shell, and the frustum block is sealed to the hollow shell. A first frustum channel is provided inside the frustum block, and the inner diameter of the first frustum channel gradually decreases from top to bottom. The first frustum channel is connected to the adjacent injection pipe, and symmetrically distributed spring plates are fixedly connected between the frustum block and the adjacent hollow shell.

[0006] Furthermore, the hollow shell contains symmetrically distributed trigger blocks, and the frustum block contains symmetrically distributed first sliding frames that are slidably connected in a sealed manner. The trigger blocks are pressed against adjacent first sliding frames. The frustum block contains linearly distributed limiting rods, and an elastic element is fixed between the limiting rods and adjacent first sliding frames. The elastic force of the spring plate is greater than the elastic force of the elastic element on the adjacent limiting rod. A sliding rod is slidably connected to the side of the first sliding frame away from the adjacent trigger block, and an elastic element is fixed between the sliding rod and the adjacent first sliding frame. Adjacent symmetrically distributed sliding rods are jointly fixed to a moving ring, and the frustum block contacts and engages with the adjacent moving ring. A second frustum channel is provided on the moving ring.

[0007] Furthermore, a limiting block is fixedly attached to the sliding rod, and a guide portion with a wavy vertical cross-section is provided on the side of the limiting rod near the adjacent limiting block. The limiting block and the guide portion of the adjacent limiting rod are pressed together.

[0008] Furthermore, the lower side of the casing is provided with an elliptical opening, and the minimum inner diameter of the casing is greater than the maximum diameter of the second frustum channel.

[0009] Furthermore, a connecting rod is slidably connected to the support frame, and a first rack is fixedly connected to one end of the connecting rod near the adjacent hollow shell. A first gear is fixedly connected to the hollow shell, and the first gear meshes with the first rack.

[0010] Furthermore, it also includes a motor, which is fixed to the support frame. The output shaft of the motor is fixed to a second gear. A squeezing rod is slidably connected to the hollow shell arranged in a linear array. A second rack that meshes with the second gear is fixed to the squeezing rod. The frustum block is squeezed into the squeezing rod. A sealing ring is fixed inside the injection pipe. A sealing block that cooperates with the sealing ring is slidably connected to the sealing ring. Symmetrically distributed elastic elements are fixed between the sealing block and the adjacent sealing ring. A collection frame located below the injection pipe arranged in a linear array is fixed to the worktable.

[0011] Furthermore, it also includes symmetrically distributed second electromagnetic sliders. The worktable is provided with symmetrically distributed second electromagnetic slide rails. The symmetrically distributed second electromagnetic sliders are slidably connected to adjacent second electromagnetic slide rails on the worktable. The second electromagnetic sliders are fixedly connected to second sliding frames. The opposing sides of the symmetrically distributed second sliding frames are all fixedly connected to fixed rods arranged in a linear array. The worktable is slidably connected to a first sliding plate located between the symmetrically distributed second sliding frames. The first sliding plate is provided with rectangular holes arranged in a linear array. The first sliding plate is slidably connected to symmetrically distributed second sliding plates. Elastic elements are fixedly connected between the symmetrically distributed second sliding plates. The fixed rods are slidably connected to adjacent second sliding plates. The opposing sides of the symmetrically distributed second sliding plates are all fixedly connected to lower clamping blocks. The lower clamping blocks are threadedly connected to symmetrically distributed threaded rods. The threaded rods are rotatably connected to upper clamping blocks located above adjacent lower clamping blocks.

[0012] Furthermore, the worktable is slidably connected with linearly distributed wedge blocks, and an elastic element is fixed between the wedge blocks and the worktable. The wedge blocks are pressed together with the first sliding plate.

[0013] Furthermore, the size of the linearly distributed wedges increases sequentially from the point closer to the first sliding plate to the point further away.

[0014] Furthermore, a production process for equal-volume feeding type traditional Chinese medicine eye patches, based on the aforementioned liquid injection device for equal-volume feeding type traditional Chinese medicine eye patch production, includes the following specific steps:

[0015] Step 1: Place and clamp the eye patch forming mold on the upper side of the symmetrically distributed first sliding plate. Then, the second electromagnetic slider drives the first sliding plate to move through the adjacent second sliding frame, the adjacent fixed rod and the adjacent second sliding plate, moving the eye patch forming mold to the bottom of the support frame.

[0016] Step 2: The connecting rod rotates the adjacent hollow shell through gear transmission, and the hollow shell drives the adjacent sleeve to rotate, so that the sleeve rotates until its projection covers the corresponding forming hole;

[0017] Step 3: After the first sliding plate moves the eye patch forming mold to the bottom of the support frame, the row of forming holes on the eye patch forming mold are aligned with the adjacent shells. The medicine pumping equipment injects several equal portions of medicine into different injection pipes. The medicine flows through the injection pipes, the adjacent first truncated cone channel, the adjacent second truncated cone channel and the adjacent shell into the adjacent forming holes on the lower eye patch forming mold.

[0018] Step 4: The adjacent frustum blocks are moved by the adjacent spring plates. During the movement of the frustum blocks, the hollow shell impacts the adjacent frustum blocks and uses continuous protrusions to limit the movement of the moving ring left and right.

[0019] Step 5: When it is necessary to temporarily stop the injection operation, the output shaft of the motor drives the squeezing rod to move up and down reciprocally through the gear and rack, continuously changing the pressure of the medicine in the first truncated cone channel;

[0020] Step 6: After the liquid injection is completed, the first sliding plate continues to move to the right. At this time, through the squeezing and cooperation between the wedge block and the first sliding plate, the elastic element of the wedge block is stretched and moved, and the wedge block passes through the adjacent holes on the first sliding plate and strikes the eye patch forming mold.

[0021] Step 7: Move and reset the parts on the device by using the second electromagnetic slider, and turn off the liquid pumping equipment, motor and the second electromagnetic slider. Clean the device for the next use.

[0022] The beneficial effects of the present invention using the above structure are as follows: 1. The present invention impacts the adjacent hollow shell by moving the frustum block. After the liquid injection is completed, the frustum block vibrates, causing the liquid attached to the first frustum channel to vibrate, thereby accelerating the dripping of the liquid attached to the first frustum channel, thus preventing the liquid from hanging on the first frustum channel and reducing the amount of liquid injected into the forming hole, thus affecting the equal amount of liquid feeding.

[0023] 2. The adjacent limiting blocks are squeezed by the limiting rod to move left and right. After the liquid injection is completed, the limiting block drives the adjacent moving ring to move left and right through the adjacent sliding rod. The moving ring shakes the liquid that is stuck on the second truncated cone channel to prevent the liquid from sticking to the second truncated cone channel, which would reduce the amount of liquid entering the forming hole and thus reduce the quality of the traditional Chinese medicine eye patch after forming.

[0024] 3. By moving the frustum block up and down, when the liquid medicine on the lower side of the first frustum channel solidifies, the frustum block moves and increases the liquid pressure between it and the adjacent sealing ring, squeezing out the solidified liquid medicine on the lower side of the first frustum channel. This prevents the liquid medicine from drying and solidifying in the first frustum channel and becoming blocked when the injection operation is temporarily stopped, thus affecting the next injection operation.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Because the gel has extremely high viscosity and the injection nozzle used in the production of traditional Chinese medicine eye patches has a small diameter, the gel solution tends to drip onto the injection nozzle when it is sprayed out, resulting in a reduction in the amount of gel solution entering the molding hole of the mold. As a result, even after equal amounts of material are fed, the amount of solution in each molding hole will still be different, which in turn affects the quality of the eye patch after molding.

[0041] Example 1: A liquid injection device for the production of equal-volume feeding type traditional Chinese medicine eye patches, such as... Figures 1-5 As shown, the device includes a workbench 1, a control panel mounted on the rear side of the workbench 1, and a first electromagnetic slide rail symmetrically distributed front and rear on the workbench 1. A first electromagnetic slider 101 is slidably connected to the first electromagnetic slide rail of the workbench 1, and the first electromagnetic slider 101 is electrically connected to the control panel for adjusting the left and right positions of a support frame 102. The symmetrically distributed first electromagnetic sliders 101 are collectively fixed to the support frame 102. A linear array of fixed blocks 103 are fixed to the lower part of the support frame 102. A linear array of injection pipes 104 are fixed to the support frame 102. The number of injection pipes 104 is the same as the number of fixed blocks 103. The injection pipes 104 are connected to a liquid pumping device, which is electrically connected to the control panel. The liquid pumping device is used to simultaneously feed equal amounts of material to all injection pipes 104. The injection pipes 104 pass through adjacent fixed blocks 103, and a rotatable connection is provided on the fixed blocks 103. A hollow shell 105 is connected to an adjacent injection pipe 104. A sleeve 106 connected to the lower side of the hollow shell 105 is fixedly connected to it. A frustum block 107 is slidably connected inside the hollow shell 105. The frustum block 107 is sealed to the adjacent hollow shell 105. A first frustum channel 1071 is provided inside the frustum block 107. The inner diameter of the first frustum channel 1071 gradually decreases from top to bottom, which is used to pressurize the liquid flowing through the first frustum channel 1071. The first frustum channel 1071 is connected to the adjacent injection pipe 104. A spring plate 108 is fixedly connected between the frustum block 107 and the adjacent hollow shell 105. The spring plate 108 is initially in a compressed state. After the frustum block 107 moves downward, the spring plate 108 will be further compressed. When the spring plate 108 rebounds, it will drive the adjacent frustum block 107 to move upward and impact the adjacent hollow shell 105.

[0042] like Figures 4-6As shown, symmetrically distributed trigger blocks 2 are fixedly connected inside the hollow shell 105. Symmetrically distributed first sliding frames 201 are slidably connected inside the frustum block 107. The trigger blocks 2 are press-fitted with adjacent first sliding frames 201 to prevent liquid from flowing to the lower side of the first sliding frame 201. A linear array of limiting rods 202 are fixedly connected inside the frustum block 107. An elastic element, a compression spring, is fixedly connected between the limiting rods 202 and adjacent first sliding frames 201. A sliding rod 203 is slidably connected to the lower side of the first sliding frame 201. An elastic element, also a compression spring, is fixedly connected between the sliding rod 203 and adjacent first sliding frames 201. The elastic element of the limiting rod 202 is initially in a compressed, stored state. The spring force of the spring plate 108 is greater than the spring force of the elastic element of the adjacent limiting rod 202, used to prevent the limiting rod 202 from... The elastic element pops out in the initial state. The adjacent symmetrically distributed sliding rods 203 are fixed together with the moving ring 204. The frustum block 107 is in contact with the adjacent moving ring 204. The moving ring 204 is provided with a second frustum channel 2041. The inner diameter of the second frustum channel 2041 gradually increases from top to bottom, and the minimum inner diameter of the second frustum channel 2041 is greater than the minimum inner diameter of the adjacent first frustum channel 1071. This is to allow the medicine in the first frustum channel 1071 to flow into the adjacent second frustum channel 2041 during the movement of the second frustum channel 2041. The lower side of the shell 106 is provided with an elliptical opening. The minimum inner diameter of the shell 106 is greater than the maximum diameter of the second frustum channel 2041. This is to prevent the medicine in the second frustum channel 2041 from flowing to the inner wall of the adjacent shell 106 when dripping.

[0043] like Figure 6 As shown, a limiting block 3 is fixed to the right side of the sliding rod 203, and a guide part with a vertical cross section of wave shape is provided on the left side of the limiting rod 202. The guide surface on the left side of the limiting rod 202 is provided with several protrusions and several depressions that are alternately distributed. The limiting block 3 is pressed and engaged with the guide part of the adjacent limiting rod 202, so that the limiting block 3 moves left and right synchronously when it moves up and down along the alternately distributed protrusions and depressions.

[0044] like Figure 2 and Figure 7 As shown, a connecting rod 5 is slidably connected to the support frame 102, a first rack 501 is fixedly connected to the lower end of the connecting rod 5, and a first gear 502 is fixedly connected to the hollow shell 105, the first gear 502 meshes with the first rack 501.

[0045] When the operator needs to use this device to inject liquid into the herbal eye patch, the operator manually places the eye patch forming mold under the support frame 102, aligning the rightmost row of forming holes on the eye patch forming mold with the adjacent shell 106. Then, the operator manually moves the connecting rod 5, which drives the first rack 501 to move. The first rack 501 drives several linearly arranged first gears 502 to rotate synchronously. The first gears 502 drive the adjacent hollow shell 105 to rotate, and the hollow shell 105 drives the adjacent shell 106 to rotate. This is used to adjust the orientation of the lower opening of the shell 106 to adapt to the shape of the forming holes. Since the forming holes of the eye patch are generally crescent-shaped and their orientation is uncertain, rotating the shell 106 allows for adjustment. 06 ensures that the projection of the elliptical opening on its lower side always covers the forming hole, preventing the liquid from splashing from one forming hole to other adjacent forming holes due to excessive pressure and collision at the bottom of the forming hole during spraying. This would cause changes in the amount of liquid in multiple forming holes, thus affecting the quality of the finished eye patch. Then, the operator turns on the liquid pumping equipment through the control panel. The liquid pumping equipment injects several equal portions of liquid into different injection pipes 104. The liquid enters the adjacent first frustum channel 1071 through the injection pipe 104. The liquid flows along the first frustum channel 1071 into the adjacent second frustum channel 2041. Finally, the liquid flows through the adjacent sleeve 106 into the adjacent forming hole on the lower eye patch forming mold.

[0046] Since the inner diameter of the first frustum channel 1071 gradually decreases from top to bottom, the downward flow of the liquid medicine will compress the inner wall of the first frustum channel 1071. This will cause the frustum block 107 to gradually move downward under the pressure of the liquid medicine, and the spring plate 108 will be gradually compressed. The frustum block 107 will drive the two adjacent limit rods 202 to move downward, and the elastic element of the limit rod 202 will gradually pop out (the elastic element of the limit rod 202 is initially in a compressed state). This will keep the first sliding frame 201 in close contact with the adjacent trigger block 2. During the downward movement of the limit rod 202, the limit rod 202 will continuously squeeze through its guide part. Pressing the adjacent limiting block 3 causes the limiting block 3 to move back and forth continuously, which in turn drives the adjacent sliding rod 203 to move back and forth left and right. When the adjacent limiting block 3 is pressed at the protrusion of the guide part on the limiting rod 202, the limiting block 3 moves to the left and drives the adjacent sliding rod 203 to move to the left, causing the elastic element of the sliding rod 203 to contract. When the adjacent limiting block 3 is in contact at the recess of the guide part on the limiting rod 202, the elastic element of the sliding rod 203 resets and drives it to move to the right. The sliding rod 203 drives the adjacent limiting block 3 to move to the right. Then, the two sliding rods 203 together drive the adjacent moving ring 204 to move left and right.

[0047] When the frustum block 107 moves downward to contact the adjacent moving ring 204, the frustum block 107 drives the adjacent moving ring 204 to move downward. The moving ring 204 drives the two adjacent sliding rods 203 to move downward. The sliding rods 203 drive the adjacent first sliding frame 201 to move, so that the first sliding frame 201 gradually moves away from the adjacent trigger block 2.

[0048] When the liquid medicine stops being injected into the injection pipe 104, the spring plate 108 rebounds and resets. The spring plate 108 rebounds and drives the adjacent frustum block 107 to move upward and reset. During the upward movement of the frustum block 107, the frustum block 107 drives the two adjacent limit rods 202 to move upward. The limit rods 202 drive the adjacent first sliding frame 201 to move upward through their elastic elements. When the first sliding frame 201 moves to contact the adjacent trigger block 2, the first sliding frame 201 is limited and can no longer move upward, so that the sliding rod 203 and the adjacent moving ring 204 both stop moving. The frustum block 107 drives the two adjacent limit rods 202 to continue to move upward. The limit rods 202 continue to move upward and squeeze their elastic elements to contract, so that the frustum block 107 and the adjacent moving ring 204 lose contact and move in opposite directions.

[0049] During the process of the frustum block 107 and the adjacent moving ring 204 moving in opposite directions, the frustum block 107 drives the adjacent limiting rod 202 to move upward. During the movement, the limiting rod 202 squeezes the adjacent limiting block 3 to move left and right through its guide part. The limiting block 3 drives the adjacent moving ring 204 to move left and right through the adjacent sliding rod 203. The moving ring 204 swings the medicine liquid adhering to the second frustum channel 2041 by moving left and right, to prevent some medicine liquid from adhering to the second frustum channel 2041, which would reduce the amount of medicine liquid entering the forming hole and thus reduce the quality of the formed Chinese medicine eye patch.

[0050] When the frustum block 107 moves upward and resets, it impacts the inner wall of the adjacent hollow shell 105. The frustum block 107 vibrates due to the impact force. Then, the frustum block 107 transmits the vibration impact force to the adjacent moving ring 204 through the two adjacent first sliding frames 201 and the two adjacent sliding rods 203. This shakes off the liquid medicine adhering to the lower side of the second frustum channel 2041, preventing the high viscosity of the liquid medicine from causing some of it to adhere to the lower side of the second frustum channel 2041, which would reduce the amount of liquid medicine entering the forming hole and thus reduce the quality of the formed Chinese medicine eye patch.

[0051] After the liquid medicine fills the rightmost set of forming holes, the operator moves the eye patch forming mold to the right so that the next set of forming holes aligns with the adjacent housing 106. The operator then repeats the above steps to inject the liquid medicine into the next set of forming holes. When all the forming holes on the eye patch forming mold are filled, the operator removes the filled eye patch forming mold and repeats the above steps to make traditional Chinese medicine eye patches. When the operator needs to stop using the device, the operator turns off the liquid medicine pumping equipment through the control panel and cleans the device for the next use.

[0052] During the production of traditional Chinese medicine eye patches, if it is necessary to temporarily stop the production of the eye patches, the gel liquid at the injection nozzle will gradually dry due to the influence of the external environment. As a result, when the operator restarts the injection device, he / she needs to clean the solidified liquid at the injection nozzle first, which makes the use of the injection device cumbersome.

[0053] Example 2: Based on Example 1, such as Figure 3 and Figures 7-10 As shown, it also includes a motor 6 electrically connected to the control panel, wherein the motor 6 is a reciprocating motor, the motor 6 is fixedly connected to the support frame 102, the output shaft of the motor 6 is fixedly connected to a second gear 601, and a pressing rod 603 is slidably connected to the hollow housing 105 arranged in a linear array. A second rack 602 that meshes with the second gear 601 is fixedly connected to the pressing rod 603. The frustum block 107 is pressed and engaged with the pressing rod 603. When the pressing rod 603 moves downward, the pressing rod 603... 03. All the frustum blocks 107 are squeezed and moved downwards. A sealing ring 604 is fixedly connected inside the injection pipe 104. A frustum-shaped through hole is provided in the middle of the sealing ring 604. A frustum-shaped sealing block 605 that is slidably connected to the sealing ring 604 and cooperates with it is sealed. There are elastic elements that are symmetrically distributed on the left and right sides between the sealing block 605 and the adjacent sealing ring 604. The elastic elements are tension springs. A collection frame located on the lower side of the injection pipes 104 distributed in a linear array is fixedly connected to the worktable 1.

[0054] When the operator removes the eye patch molding mold and needs to temporarily stop the liquid injection operation, the operator turns off the liquid pumping equipment and turns on the motor 6 through the control panel, so that the output shaft of the motor 6 rotates back and forth and drives the second gear 601 to rotate back and forth. The second gear 601 drives the second rack 602 to move up and down back and forth, and the second rack 602 drives the extrusion rod 603 to move up and down back and forth.

[0055] When the extrusion rod 603 moves downward, it drives all the frustum blocks 107 to move downward. The frustum blocks 107 move downward and repeat the above steps, causing the adjacent moving rings 204 to vibrate continuously, preventing the liquid medicine from accumulating on the moving rings 204 and blocking the adjacent second frustum channel 2041. As the frustum blocks 107 move downward, the spring plate 108 is also gradually compressed. If the liquid medicine on the lower side of the first frustum channel 1071 solidifies at this time, the lower side of the first frustum channel 1071 is blocked by the solidified block of liquid medicine. The frustum block 107 temporarily forms a closed piston head. The frustum block 107 moves downward and draws out the liquid medicine above it. The liquid medicine flows downward and drives the sealing block 605 to move downward, causing the elastic element of the sealing block 605 to contract. The sealing block 605 moves and creates a gap between it and the adjacent sealing ring 604. The liquid medicine flows through the gap between the sealing ring 604 and the adjacent sealing block 605 into the adjacent first frustum channel 1071.

[0056] When the extrusion rod 603 moves upward, the spring plate 108 rebounds and gradually drives the adjacent frustum block 107 to move and reset. The frustum block 107, through the liquid on its upper side, squeezes the adjacent sealing block 605 to move upward and reset. The elastic element of the sealing block 605 rebounds and resets synchronously, so that the sealing ring 604 is blocked by the adjacent sealing block 605. During the upward movement of the frustum block 107, the frustum block 107 squeezes the liquid on its upper side. The liquid pressure between the sealing ring 604 and the adjacent frustum block 107 gradually increases, causing the blocky liquid on the lower side of the first frustum channel 1071 to be squeezed out. Then the squeezed blocky liquid falls into the collection frame of the workbench 1 and is collected by the operator. This avoids the liquid from drying and solidifying in the first frustum channel 1071 and becoming blocked when the injection operation is stopped for a short time, which would affect the next injection operation. When the operator needs to stop using this device for a long time, the operator can turn off the motor 6 through the control panel.

[0057] Because the gel solution has high viscosity and low fluidity, if the gel solution itself is viscous after being injected into the molding hole, causing the gel solution to accumulate in the central area of ​​the molding hole and not easily spread, the filling amount in the edge area of ​​the molded eye patch will be reduced, thus affecting the quality of the finished eye patch.

[0058] Example 3: Based on Example 2, such as Figure 11-13As shown, it also includes symmetrically distributed second electromagnetic sliders 7, which are electrically connected to the control panel. The worktable 1 is provided with symmetrically distributed second electromagnetic slide rails. The symmetrically distributed second electromagnetic sliders 7 are slidably connected to adjacent second electromagnetic slide rails on the worktable 1. Each second electromagnetic slider 7 is fixedly connected to a second sliding frame 701. Opposite sides of the symmetrically distributed second sliding frames 701 are fixedly connected to linearly arranged fixing rods 702. A first sliding plate 703 located between the symmetrically distributed second sliding frames 701 is slidably connected to the worktable 1. The first sliding plate 703 supports the eye patch forming mold and has a linearly arranged rectangular hole. The first sliding plate 703 is slidably connected to symmetrically distributed second sliding plates 704. An elastic element, specifically a compression spring, is fixedly connected between the symmetrically distributed second sliding plates 704. The fixing rods 702 slide against adjacent second sliding plates 704. The connection is made so that the fixing rod 702 is inserted into the adjacent second sliding plate 704 to guide the second sliding plate 704. Lower clamping blocks 705 are fixedly connected to the opposite sides of the symmetrically distributed second sliding plates 704. Multiple fixed points are arranged in a linear array between the second sliding plate 704 and the adjacent lower clamping blocks 705. These linear array fixed points are staggered with the adjacent linear array of fixing rods 702. The lower clamping blocks 705 are threaded with symmetrically distributed... The threaded rod 707 is rotatably connected to an upper clamping block 706 located above the adjacent lower clamping block 705. When the threaded rod 707 rotates counterclockwise, it gradually unscrews from the adjacent lower clamping block 705, causing the adjacent upper clamping block 706 to move upward. When the threaded rod 707 rotates clockwise, it gradually screws into the adjacent lower clamping block 705, causing the adjacent upper clamping block 706 to move downward.

[0059] like Figure 11 As shown, several wedge-shaped blocks 8 are slidably connected on the worktable 1 in a straight line. An elastic element, which is a compression spring, is fixed between the wedge-shaped blocks 8 and the worktable 1. The wedge-shaped blocks 8 are pressed and engaged with the first sliding plate 703. After the first sliding plate 703 moves to the right and presses the adjacent wedge-shaped block 8, the wedge-shaped block 8 moves downward and presses its elastic element to contract. After the rectangular hole of the first sliding plate 703 moves to the lower side of the adjacent wedge-shaped block 8, the elastic element of the wedge-shaped block 8 pops out and drives it to pass through the adjacent rectangular hole on the first sliding plate 703. The size of the straight-line distributed wedge-shaped blocks 8 gradually increases from left to right. As the liquid medicine gradually solidifies, the impact force of the wedge-shaped blocks 8 on the eye patch forming mold gradually increases.

[0060] When the operator needs to use this device to inject the herbal eye patch, the operator rotates the threaded rod 707. The two adjacent threaded rods 707 rotate and together drive the adjacent upper clamping block 706 upwards. The upper clamping block 706 gradually moves away from the adjacent lower clamping block 705. Then, the operator places the eye patch forming mold on the upper side of the two first sliding plates 703 and manually drives the two lower clamping blocks 705 to move in opposite directions. The lower clamping blocks 705 drive the second sliding plate 704 to move, and the elastic element of the second sliding plate 704 contracts. Then, the operator places the front and rear parts of the eye patch forming mold between the adjacent lower clamping block 705 and the adjacent upper clamping block 706 respectively. The operator then rotates the threaded rod 707 to its original position, causing the adjacent upper clamping block 706 to move downwards. The movement causes the gap between the lower clamping block 705 and the adjacent upper clamping block 706 to gradually decrease, clamping the front and rear parts of the eye patch forming mold. Then, the operator releases the lower clamping block 705, causing the elastic element between the two second sliding plates 704 to have a tendency to spring back and reset. This causes the second sliding plate 704, the adjacent lower clamping block 705, and the adjacent upper clamping block 706 to have a tendency to move laterally and reset. The lower clamping block 705 and the adjacent upper clamping block 706 clamp and stretch the eye patch forming mold, so that the front and rear parts of the eye patch forming mold are subjected to the force of moving in opposite directions, stretching the eye patch forming mold and preventing wrinkles on the surface of the eye patch forming mold from causing wrinkles in its forming holes, which would result in wrinkles on the formed eye patch and thus affect the fit of the finished eye patch during use.

[0061] After the clamping block 705 and the adjacent upper clamping block 706 clamp the eye patch forming mold, the operator activates the second electromagnetic slider 7 through the control panel. The second electromagnetic slider 7 drives the adjacent linear array of fixed rods 702 to move to the right through the adjacent second sliding frame 701. The fixed rods 702 drive the adjacent second sliding plate 704 to move to the right. The two second sliding plates 704 together drive the first sliding plate 703 to move to the right.

[0062] When the first sliding plate 703 moves the eye patch forming mold above it to the lower side of the linearly distributed injection pipes 104, the operator controls the second electromagnetic slider 7 to stop moving via the control panel. Then, the operator injects liquid into the eye patch forming mold through the above steps. When the liquid fills a set of linearly distributed forming holes, the operator controls the second electromagnetic slider 7 to move to the right via the control panel. At this time, during the movement of the second electromagnetic slider 7 to the right, the second electromagnetic slider 7 drives the first sliding plate 703 to move to the right through the adjacent second sliding frame 701, the adjacent fixed rod 702, and the adjacent second sliding plate 704. When the first sliding plate 703 moves to contact the leftmost wedge block 8, the first sliding plate 703... When the leftmost wedge 8 is squeezed, the elastic element of the leftmost wedge 8 contracts under pressure. When the wedge 8 moves to align with the adjacent rectangular hole on the first sliding plate 703, the elastic element of the wedge 8 pops out and drives it to reset. The wedge 8 passes through the adjacent hole on the first sliding plate 703 and strikes the eye patch forming mold. This process is repeated. Several wedges 8 arranged in a linear array strike the eye patch forming mold in turn, knocking out air bubbles in the liquid medicine in the forming hole. This prevents air bubbles in the liquid medicine in the forming hole from reducing the quality of the finished product. At the same time, by striking the bottom of the eye patch forming mold, the liquid medicine in the forming hole is vibrated to enhance the fluidity of the liquid medicine, thereby preventing the liquid medicine from accumulating in the central area of ​​the forming hole and causing the edge area of ​​the forming hole to be incompletely filled.

[0063] When the operator needs to stop using the device, the operator rotates the threaded rod 707 to release the clamping block 705 and the adjacent upper clamping block 706 from the eye patch forming mold. Then, the eye patch forming mold after the liquid injection is completed is removed and collected. The second electromagnetic slider 7 is then reset via the control panel. The second electromagnetic slider 7 moves and resets the parts on it. Finally, the liquid pumping equipment, motor 6, and second electromagnetic slider 7 are turned off via the control panel, and the device is cleaned for the next use.

[0064] Example 4: Based on Example 3, a production process for equal-volume feeding type traditional Chinese medicine eye patches, using the above-mentioned liquid injection device for equal-volume feeding type traditional Chinese medicine eye patch production, includes the following specific steps:

[0065] Step 1: Place and clamp the eye patch forming mold on the upper side of the symmetrically distributed first sliding plate 703. Then, the second electromagnetic slider 7 drives the first sliding plate 703 to move through the adjacent second sliding frame 701, the adjacent fixed rod 702 and the adjacent second sliding plate 704, moving the eye patch forming mold to the bottom of the support frame 102.

[0066] Step 2: The connecting rod 5 rotates the adjacent hollow shell 105 through gear transmission. The hollow shell 105 drives the adjacent sleeve 106 to rotate, so that the sleeve 106 rotates until its projection covers the corresponding forming hole.

[0067] Step 3: When the first sliding plate 703 moves the eye patch forming mold to below the support frame 102, the row of forming holes on the eye patch forming mold are aligned with the adjacent shells 106. The medicine pumping equipment injects equal amounts of medicine into different injection pipes 104. The medicine flows through the injection pipes 104, the adjacent first frustum channel 1071, the adjacent second frustum channel 2041 and the adjacent shells 106 into the adjacent forming holes on the lower eye patch forming mold.

[0068] Step 4: The adjacent frustum block 107 is moved by the adjacent spring plate 108. During the movement of the frustum block 107, the hollow shell 105 impacts the adjacent frustum block 107 and uses the continuous protrusion limit to make the moving ring 204 move left and right, so as to throw off the liquid medicine on the moving ring 204 and the frustum block 107.

[0069] Step 5: When it is necessary to temporarily stop the injection operation, the output shaft of the motor 6 drives the extrusion rod 603 to move up and down reciprocally through the gear and rack, continuously changing the pressure of the medicine in the first frustum channel 1071;

[0070] Step 6: After the liquid injection is completed, the first sliding plate 703 continues to move to the right. At this time, through the squeezing and cooperation between the wedge block 8 and the first sliding plate 703, the elastic element of the wedge block 8 extends and retracts and drives it to move. The wedge block 8 passes through the adjacent holes on the first sliding plate 703 and strikes the eye patch forming mold.

[0071] Step 7: Move and reset the parts on the second electromagnetic slider 7, and turn off the liquid pumping equipment, motor 6 and the second electromagnetic slider 7. Clean the device for the next use.
