Description

Technical Field

[0001] The invention relates to the technical field of hot compress patch preparation, in particular to a method for preparing a hot compress patch. Background Art

[0002] Hot compress patch products are physical heating patch products that treat diseases through the mechanism of hot compress therapy. The hot compress patch is mainly composed of four parts: a Chinese medicine paste layer, a raw material layer, a gelatin layer and a non-woven bag. The raw material layer is placed in the non-woven bag, and the gelatin layer is used to make the patch adhere to the clothes. It can produce an exothermic reaction under the action of oxygen in the air. The hot compress patch is prepared by stamping the Chinese medicine paste layer, the raw material layer, the gelatin layer and the non-woven bag together, and then cutting them into various shapes by die-cutting.

[0003] The existing hot compress patch preparation device has the following disadvantages:

[0004] 1. When extruding raw materials, a mold pressing plate is used for extrusion. Although it can play a role in pressing, a small amount of air may be squeezed into the material layers, resulting in bubbles and affecting product quality. At the same time, since both the Chinese medicine paste layer and the soft layer are flexible layers, vertical extrusion will also produce uneven force;

[0005] 2. During the die-cutting process, since the cutting is done by a one-way cutter, although the cutting efficiency is high, the cut hot compress may adhere to the cutter and be driven for a distance before falling, affecting the placement position. At the same time, burrs are easily generated on the edges of the hot compress during cutting. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a method for preparing a hot compress patch, which is achieved by the following specific technical means:

[0007] A method for preparing a hot compress patch, using a hot compress patch preparation device, comprising a transport frame, a support base is installed on both sides of the lower end surface of the transport frame by a fixed connection method, and a conveyor belt is arranged on the outer surface of the transport frame, and a driving motor is fixedly installed on the rear end of the right side surface of the transport frame, a stamping box is installed on both sides of the upper end surface of the transport frame by a fixed connection method, and a cutting box is fixedly installed on both sides of the upper end surface of the transport frame at a position in front of the stamping box, and a winding box is fixedly installed on the upper end surface of the cutting box;

[0008] Four stamping cylinders are installed in a matrix distribution at the top of the inner part of the stamping box by means of fixed connection, and a stamping block is fixedly installed at the lower ends of the four stamping cylinders, a rotating motor is fixedly installed at the front end of the inner part of the stamping block, and an inner gear ring is embedded and installed at a position below the rotating motor inside the stamping block, and a linear slide is embedded and installed at a position below the inner gear ring inside the stamping block, a driven gear is meshedly connected to the inner surface of the inner gear ring, a driven slide rod is slidably connected to the lower end of the driven gear, and a connecting slider sliding inside the linear slide rail is fixedly connected to the lower end of the driven slide rod;

[0009] The preparation method of the hot compress patch comprises the following steps:

[0010] S1: placing a material layer composed of a Chinese medicine paste layer, a raw material layer, a gelatin layer and a non-woven bag stacked horizontally on the surface of a conveyor belt;

[0011] S2: The driving motor is started to drive the conveyor belt to move forward through the punching box and the cutting box;

[0012] S3: The material layer passes under the punch box and is squeezed into a whole piece;

[0013] S4: The material layer is cut into hot compress patches after passing under the cutting box. The hot compress patches move forward along the conveyor belt, and the remaining material layer is wound on the surface of the winding roller.

[0014] Furthermore: the output shaft of the rotating motor is fixedly connected to the active turntable, and a connecting rod rotatably connected to the driven gear is fixedly connected at the middle position of the lower end surface of the active turntable, and a reciprocating pressure block is fixedly connected to the lower surface of the connecting slider, and the lower end surface of the reciprocating pressure block is an arc surface. Starting the rotating motor can drive the active turntable to rotate. When the active turntable rotates, it drives the driven gear to rotate along the inner wall of the inner gear ring, and then drives the driven slide rod slidably connected to the driven gear to slide left and right. When the driven slide rod slides, it drives the connecting slide rod inside the linear slide rail to move synchronously, and the reciprocating pressure block under the connecting slide rod also moves with it.

[0015] Furthermore: the rear ends of the inner walls on both sides of the cutting box are fixedly connected with guide correction plates, and a cutting cylinder is fixedly installed in front of the inner top surface of the cutting box, and a downward pressure mounting plate is fixedly installed on the lower surface of the cutting cylinder. The front of the inner walls on both sides of the cutting box are rotatably connected with lower guide rollers. After the material layer is calibrated by the guide correction plate, it arrives directly below the downward pressure mounting plate. After cutting, the material layer a bypasses the lower guide roller and moves upward.

[0016] Furthermore: three external cutting knives with the same spacing are installed on the lower surface of the downward pressing mounting plate by a fixed connection manner; a trigger top block is slidably installed on the lower end surface of the downward pressing mounting plate at the middle position of the three external cutting knives; an upper connecting block is fixedly connected to the upper end surface of the trigger top block; a reset spring connected to the inner wall of the downward pressing mounting plate is fixedly installed on the upper end surface of the upper connecting block; the thickness of the three external cutting knives is greater than the thickness of the material layer a; the initial position height of the lower end of the trigger top block is lower than the thickness of the material layer; when pressing down for cutting, the material layer a will squeeze the trigger top block upward; when the trigger top block is squeezed, the reset spring is moved upward to make the upper connecting block also move upward; when the cutting is completed, the trigger top block returns to its original position.

[0017] Further: a side fixing block is fixedly installed inside the lower pressure mounting plate at the front and rear positions of the upper connecting block, a side fixing block is fixedly connected to a side surface close to the upper connecting block with a side connecting spring, an end of the side connecting spring close to the upper connecting block is fixedly connected to a driven push block, the front and rear lower surfaces of the upper connecting block are both inclined surfaces, the surfaces where the driven push block and the lower end surfaces of the upper connecting block fit together are matching inclined surfaces, in the initial state (as shown in the figure), the side connecting spring is in a compressed state, when the upper connecting block moves upward, the lower end surface of the upper connecting block is separated from the upper end surface of the driven push block, and the side connecting spring pushes the driven push block to slide to the side close to the upper connecting block, and similarly, when the trigger top block returns to its original position, the side connecting spring drives the driven push block to reset.

[0018] Furthermore: the lower end of the driven push block is fixedly connected with a side inclined slot plate, and the interior of the lower pressure mounting plate is slidably mounted with a driven plate at a front and rear position of the side inclined slot plate. When the driven push block slides toward the side close to the upper connecting block, it drives the driven plate to move synchronously.

[0019] Furthermore: an inclined slider is fixedly installed on one side surface of the driven plate close to the side inclined slot plate, and a sliding groove that matches the slider on the surface of the driven plate is opened on one side surface of the side inclined slot plate close to the driven plate. When the driven plate slides toward the side close to the upper connecting block, the slider on its surface slides along the inclined slot on the surface of the side inclined slot plate, driving the driven plate to move downward. Similarly, when the driven push block is reset, the driven plate is reset upward.

[0020] Furthermore: an inner cutter is fixedly installed at the lower end of the driven plate, and a surface of the inner cutter close to the outer cutter fits with the outer cutter. When the driven plate moves downward, the inner cutter also moves synchronously to cut the material layer on the inside to avoid adhesion between the material layer and the outer cutter. The two-way cutting also reduces burrs on the edges.

[0021] Furthermore: an upper guide roller is provided at the front of the interior of the winding box, and a winding roller is provided at the rear of the interior of the winding box, a winding shaft connected to the winding roller through a transmission belt is fixedly installed on the upper surface of the cutting box located at the rear position of the winding box, and a winding motor is fixedly installed on the right surface of the cutting box, and the upward material layer bypasses the upper guide roller and is wound on the surface of the winding roller, the output shaft of the winding motor is fixedly connected to the winding roller, and the winding shaft is connected to both sides of the winding roller through a conveyor belt, and the material layer a is wound by starting the winding motor to drive the winding roller to rotate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The preparation method of the hot compress patch can smooth and extrude the material layer during extrusion through the setting of the internal structure of the punching box. The lateral movement can squeeze out the internal air while the force is evenly applied to avoid the generation of bubbles. At the same time, the extrusion force is even, and smoothing is performed from two relative angles, which increases work efficiency.

[0024] 2. The preparation method of the hot compress patch, through the setting of the internal structure of the cutting box and the winding box, can cut the material layer on the inside after a round of cutting is completed, so as to avoid the material layer and the outer cutting knife from sticking to each other when the cutting knife rises. The two-way cutting also reduces the burrs on the edges and improves the product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See also Figure 4 , Figure 5 and Figure 6 The top of the inner part of the stamping box 4 is installed with four stamping cylinders 41 in a matrix distribution through a fixed connection mode, and a stamping block 42 is fixedly installed at the lower ends of the four stamping cylinders 41. A rotating motor 43 is fixedly installed at the front end of the inner part of the stamping block 42, and an internal gear ring 47 is embedded and installed at a position below the rotating motor 43 inside the stamping block 42, and a linear slide rail 48 is embedded and installed at a position below the internal gear ring 47 inside the stamping block 42, and a driven gear 46 is meshingly connected to the inner surface of the internal gear ring 47, and a driven slide rod 461 is slidably connected to the lower end of the driven gear 46, and a connecting slider 49 sliding inside the linear slide rail 48 is fixedly connected to the lower end of the driven slide rod 461. The stamping block 42 can be driven downward by the four stamping cylinders 41. The height of the stamping block 42 is adjusted before use so that it is located above the material layer a.

[0044] See also Figure 4 , Figure 5 and Figure 6 The output shaft of the rotating motor 43 is fixedly connected to the driving rotating disk 44. A connecting rod 45 is fixedly connected to the middle position of the lower end surface of the driving rotating disk 44 and is rotatably connected to the driven gear 46. A reciprocating pressure block 491 is fixedly connected to the lower surface of the connecting slider 49. The lower end surface of the reciprocating pressure block 491 is an arc surface. Starting the rotating motor 43 can drive the driving rotating disk 44 to rotate. When the driving rotating disk 44 rotates, it drives the driven gear 46 to rotate along the inner wall of the inner gear ring 47, and then drives the driven slide rod 461 slidably connected to the driven gear 46 to slide left and right. When the driven slide rod 461 slides, it drives the connecting slide rod 49 inside the linear slide rail 48 to move synchronously, and the reciprocating pressure block 491 under the connecting slide rod 49 also moves with it.

[0045] The reciprocating pressing blocks 491 on both sides smooth and squeeze the material layer a when moving forward and backward. The lateral movement can squeeze out the internal air while applying uniform force to avoid the generation of bubbles.

[0046] See also Figure 7 , Figure 8 and Fig. 9 The rear ends of the inner walls on both sides of the cutting box 5 are fixedly connected with guide correction plates 52, and a cutting cylinder 53 is fixedly installed in front of the inner top surface of the cutting box 5, and a downward pressing mounting plate 54 is fixedly installed on the lower surface of the cutting cylinder 53. The front of the inner walls on both sides of the cutting box 5 is rotatably connected with lower guide rollers 51. After the material layer a is calibrated by the guide correction plate 52, it arrives directly below the downward pressing mounting plate 54. After cutting, the material layer a bypasses the lower guide roller 51 and moves upward.

[0047] See also Figure 7 , Figure 8 and Fig. 9 The lower surface of the pressing mounting plate 54 is fixedly connected with three external cutting knives 55 with the same spacing. The lower end surface of the pressing mounting plate 54 is slidably installed with a trigger top block 541 at the middle position of the three external cutting knives 55. The upper end surface of the trigger top block 541 is fixedly connected with an upper connecting block 543. The upper end surface of the upper connecting block 543 is fixedly installed with a return spring 542 connected to the inner wall of the pressing mounting plate 54. The thickness of the three external cutting knives 55 is greater than the thickness of the material layer a. The initial position height of the lower end of the trigger top block 541 is lower than the thickness of the material layer a. When pressing down and cutting, the material layer a will squeeze the trigger top block 541 upward. When the trigger top block 541 is squeezed, the return spring 542 is moved upward to squeeze the upper connecting block 543, so that the upper connecting block 543 also moves upward. When the cutting is completed, the trigger top block 541 returns to its original position.

[0048] See also Figure 7 , Figure 8 and Fig. 9 , a side fixing block 545 is fixedly installed inside the downward pressing mounting plate 54 at the front and rear positions of the upper connecting block 543, a side connecting spring 544 is fixedly connected to a side surface of the side fixing block 545 close to the upper connecting block 543, and a driven push block 549 is fixedly connected to one end of the side connecting spring 544 close to the upper connecting block 543. The front and rear lower surfaces of the upper connecting block 543 are both inclined surfaces, and the surface of the driven push block 549 that fits with the lower end surface of the upper connecting block 543 is a matching inclined surface. In the initial state (such as Figure 8 ), the side connecting spring 544 is in a compressed state. When the upper connecting block 543 moves upward, the lower end surface of the upper connecting block 543 is separated from the upper end surface of the driven push block 549, and the side connecting spring 544 pushes the driven push block 549 to slide toward the side close to the upper connecting block 543. Similarly, when the trigger top block 541 returns to its original position, the side connecting spring 544 drives the driven push block 549 to reset.

[0049] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 The lower end of the driven push block 549 is fixedly connected with a side inclined slot plate 546, and a driven plate 547 is slidably installed inside the downward pressure mounting plate 54 at the front and rear positions of the side inclined slot plate 546. When the driven push block 549 slides toward the side close to the upper connecting block 543, it drives the driven plate 547 to move synchronously.

[0050] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 A tilted slider is fixedly installed on one side surface of the driven plate 547 close to the side inclined slot plate 546, and a sliding groove that matches the slider on the surface of the driven plate 547 is opened on one side surface of the side inclined slot plate 546 close to the driven plate 547. When the driven plate 547 slides toward the side close to the upper connecting block 543, the slider on its surface slides along the inclined groove on the surface of the side inclined slot plate 546, driving the driven plate 547 to move downward. Similarly, when the driven push block 549 is reset, the driven plate 547 is reset upward.

[0051] See also Figure 7 , Figure 8 and Fig. 9 An inner cutter 548 is fixedly installed at the lower end of the driven plate 547. The side surface of the inner cutter 548 close to the outer cutter 55 is in contact with the outer cutter 55. When the driven plate 547 moves downward, the inner cutter 548 also moves synchronously to cut the material layer a on the inside to avoid the material layer from sticking to the outer cutter 55. The two-way cutting also reduces burrs on the edges.

[0052] See also Figure 1 , Figure 2 and Figure 7 An upper guide roller 64 is provided at the front of the winding box 6, and a winding roller 63 is provided at the rear of the winding box 6. A winding shaft 61 connected to the winding roller 63 through a transmission belt is fixedly installed on the upper surface of the cutting box at the rear position of the winding box 6. A winding motor 62 is fixedly installed on the right surface of the cutting box. The upward material layer a bypasses the upper guide roller 64 and is wound on the surface of the winding roller 63. The output shaft of the winding motor 62 is fixedly connected to the winding roller 63. The winding shaft 61 is connected to both sides of the winding roller 63 through a conveyor belt. The material layer a is wound by starting the winding motor 62 to drive the winding roller 63 to rotate.

[0053] Working principle: When in use, a material layer a composed of a Chinese medicine paste layer, a raw material layer, a gelatin layer and a non-woven bag stacked horizontally is placed on the surface of a conveyor belt 3, and the conveyor belt 3 is driven forward by a driving motor 31 to pass through a punching box 4 and a cutting box 5, and the front end of the material layer a passes through the surface of a lower guide roller 51 and an upper guide roller 64 and is wound on the surface of a winding roller 63;

[0054] Starting the rotating motor 43 can drive the active turntable 44 to rotate. When the active turntable 44 rotates, it drives the driven gear 46 to rotate along the inner wall of the inner gear ring 47, and then drives the driven slide bar 461 that is slidably connected to the driven gear 46 to slide left and right. When the driven slide bar 461 slides, it drives the connecting slide block 49 inside the linear slide rail 48 to move synchronously, and the reciprocating pressure block 491 under the connecting slide block 49 also moves with it. When the reciprocating pressure blocks 491 on both sides move horizontally, they smooth and extrude the material layer a. While being evenly stressed, the horizontal movement can squeeze out the air inside to avoid the generation of bubbles.

[0055] When pressing down to cut, the material layer a will press the trigger top block 541 upwards. When the trigger top block 541 is squeezed, the squeeze reset spring 542 moves upwards, so that the upper connecting block 543 also moves upwards. When the cutting is completed, the trigger top block 541 returns to its original position. When the upper connecting block 543 moves upwards, the lower end surface of the upper connecting block 543 is separated from the upper end surface of the driven push block 549, and the side connecting spring 544 pushes the driven push block 549 to slide to the side close to the upper connecting block 543. Similarly, when the trigger top block 541 returns to its original position, the side connecting spring 544 drives the driven push block 549 to return to its original position.

[0056] When the driven push block 549 slides toward the side close to the upper connecting block 543, the driven plate 547 is driven to move synchronously. When the driven plate 547 slides toward the side close to the upper connecting block 543, the slider on its surface slides along the inclined groove on the surface of the side inclined groove plate 546, driving the driven plate 547 to move downward. Similarly, when the driven push block 549 is reset, the driven plate 547 is reset upward. The driven plate 547 moves downward and the inner cutter 548 also moves synchronously to cut the material layer a on the inner side to avoid the material layer from adhering to the outer cutter 55. The two-way cutting also reduces the burrs on the edge.

[0057] The material layer a is wound around the upper guide roller 64 and wound on the surface of the winding roller 63. The output shaft of the winding motor 62 is fixedly connected to the winding roller 63. The winding shaft 61 is connected to both sides of the winding roller 63 through a conveyor belt. The winding motor 62 is started to drive the winding roller 63 to rotate and the material layer a is wound.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
