Description

Technical Field

[0001] This invention relates to a production line for a wing-shaped moxibustion patch. Background Technology

[0002] The winged moxibustion patch has one side of the inner wrapping attached to the middle of an adhesive elastic fabric (the adhesive elastic fabric is formed by cutting the bottom roll material), with wings on both sides of the adhesive elastic fabric, and the other side of the inner wrapping and the wings covered by release paper.

[0003] The production speed of inner packaging forming equipment is relatively slow, and it usually adopts a group feeding method, which leads to inconsistent front and rear spacing between inner packaging groups. In addition, the production speed of wing-type moxibustion patch composite equipment is faster. Therefore, the inner packaging sent out by the inner packaging forming equipment is usually collected manually, and then the inner packaging is placed into the material hopper of the wing-type moxibustion patch composite equipment manually. This method of collecting and refeeding materials makes the labor intensity of operators high and the working efficiency of wing-type moxibustion patch composite equipment low.

[0004] The existing wing-type moxibustion patch composite equipment relies on conventional conveying devices for feeding. The inner packs in the hopper are intermittently sent to the conventional conveying device for continuous conveying in order to feed the inner packs of the wing-type moxibustion patch composite equipment. As a result, the spacing between the inner packs on the conventional conveying device is relatively long, which leads to the waste of the bottom roll material.

[0005] Furthermore, the wing-type moxibustion patch composite equipment has high requirements for the spacing and posture of the inner pack. If the inner pack exhibits the aforementioned irregularities (i.e., inconsistent spacing) or skewed posture (i.e., lateral displacement), the material will be in a forward-backward and / or lateral displacement state on the cut strip of adhesive elastic cloth (see...). Figure 9 This results in the bottom adhesive elastic fabric having more exposed areas on one side and less on the other. The excess exposed areas tend to overlap and stick together after packaging, making it difficult to unfold the finished product during use and reducing the user experience. It can even lead to inaccurate cutting positions or waste cutting, severely reducing the pass rate of the finished moxibustion patches. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a production line for wing-shaped moxibustion patches. The inner packaging forming equipment and the wing-shaped moxibustion patch composite equipment are connected by a variable speed conveyor belt and an equal-spacing conveyor mechanism to form a production line for wing-shaped moxibustion patches. The equal-spacing conveyor mechanism can ensure that the inner packaging is spaced evenly at the front and back and enters the wing-shaped moxibustion patch composite equipment with a small gap.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a production line for wing-shaped moxibustion patches, wherein a variable-speed conveyor belt and an equally spaced conveying mechanism are connected between the inner packaging forming equipment and the wing-shaped moxibustion patch composite equipment; the discharge end of the variable-speed conveyor belt is connected to the inlet end of the equally spaced conveying mechanism; the equally spaced conveying mechanism includes an integrated conveying component and a variable-speed adjustment component, the integrated conveying component includes a main conveyor belt and an auxiliary conveyor belt arranged in parallel, both the main conveyor belt and the auxiliary conveyor belt are equipped with longitudinally equally spaced push blocks, and there is a material placement cavity between adjacent push blocks; when the main conveyor belt receives the inner packaging sent out by the variable-speed conveyor belt, there is a material placement cavity between the inner packaging. The auxiliary conveyor belt has an empty material storage chamber. A suction robot transfers the inner packages to the empty material storage chamber on the main conveyor belt for integration, ensuring the inner packages delivered by the main conveyor belt are arranged longitudinally at intervals. The discharge end of the main conveyor belt connects to the input end of the speed adjustment component. The speed adjustment component includes a correction unit and a spacing adjustment unit. The correction unit includes a stationary material support plane and a correction push plate. The correction push plate pushes the inner packages on the stationary material support plane into the spacing adjustment unit. The spacing adjustment unit includes a variable-speed conveying plane. By controlling the conveying speed of the variable-speed conveying plane, the inner packages are conveyed at equal intervals after entering the wing-type moxibustion patch composite equipment.

[0008] This invention uses a variable-speed conveyor belt to deliver the inner packages to the main and auxiliary conveyor belts. Pushers contact the edges of the inner packages to push them forward. A suction robot transfers the inner packages from the auxiliary conveyor belt to the main conveyor belt in a single-row arrangement, matching the production process of the inner package forming equipment with that of the wing-type moxibustion patch composite equipment. The main conveyor belt then delivers the inner packages one by one to a stationary support plane. This stationary support plane connects the variable-speed conveyor plane and the main conveyor belt, shortening the distance between the inner packages and allowing for posture correction. Additionally, a correction pusher plate corrects the posture of the inner packages during the pushing process, ensuring they enter the variable-speed conveyor plane correctly to meet its feeding requirements. Finally, by controlling the conveying speed of the variable-speed conveyor plane, the inner packages are arranged at equal intervals within the wing-type moxibustion patch composite equipment. This achieves the integration of the inner package forming equipment and the wing-type moxibustion patch composite equipment, forming a production line for wing-type moxibustion patches that improves the utilization rate of the bottom roll material and the yield of the wing-type moxibustion patch composite equipment.

[0009] Preferably, the stationary material support plane is located on the support plate, and the support plate has a pushing gap for the correction push plate to extend into and move horizontally. The pushing gap allows the correction push plate to extend into, ensuring that the correction push plate contacts the inner edge of the package, thus achieving stable feeding.

[0010] Preferably, the correction push plate is connected to the material pushing drive mechanism, which includes a lifting drive component and a lateral drive component. The lifting drive component drives the correction push plate to move up and down, and the lateral drive component drives the correction push plate to move horizontally.

[0011] Furthermore, a pressure plate is configured on the correction push plate, and the pressure plate is positioned vertically opposite to the stationary material support plane. The pressure plate can flatten the inner package, preventing the edges of the inner package from curling up and entering subsequent processes, thus affecting the yield.

[0012] Preferably, the spacing adjustment unit further includes an alignment conveying component, a variable-speed drive motor, a position sensor, and a controller. The variable-speed conveying plane is formed on the alignment conveying component; the variable-speed drive motor is drively connected to the alignment conveying component; the position sensor is used to detect the actual position of the inner package on the variable-speed conveying plane; the controller is electrically connected to both the position sensor and the variable-speed drive motor. The position sensor detects the actual position of the inner package within the alignment conveying component and sends the inner package position signal to the controller. The controller controls the conveying speed of the variable-speed alignment conveying component based on the deviation between the actual distance and the set distance between the inner package position signal and the set position, to ensure that the inner packages are conveyed rhythmically, that the spacing between the inner packages is equal, reduce losses, and improve the yield.

[0013] Furthermore, the alignment conveying assembly includes a first synchronous belt and a second synchronous belt that operate synchronously, positioned vertically opposite each other, with the variable-speed conveying plane formed between the first and second synchronous belts. The first and second synchronous belts clamp and convey the inner package, improving transmission efficiency and ensuring the conveying accuracy of the inner package.

[0014] Furthermore, the correction pusher plate is drive-connected to the material pushing drive mechanism, which is electrically connected to the controller. The variable-speed conveying plane includes an initial first speed and a second speed determined by a signal sent by a position sensor. The controller controls the material pushing drive mechanism to match the pushing speed of the correction pusher plate with the first speed. After receiving a signal from the position sensor indicating the arrival of material on the variable-speed conveying plane, the position sensor sends a command to the variable-speed drive motor via the controller to achieve a speed change of the variable-speed conveying plane at the second speed. This reduces the speed difference of the material before entering the variable-speed conveying plane, thereby further improving the yield rate.

[0015] Preferably, the variable speed conveyor belt is equipped with a sensor for detecting the position of the inner package at the feed end. The variable speed conveyor belt is positioned above the integrated conveying assembly, and there is a material placement cavity between adjacent push blocks. The controller adjusts the conveying speed of the variable speed conveyor belt according to the inner package position signal from the position sensor to ensure that the inner package enters the material placement cavity stably.

[0016] Furthermore, the discharge end of the variable speed conveyor belt is equipped with a guide plate assembly, which has a converging material guiding channel. The number of the material guiding channels corresponds to the number of inner package rows, and the outlet of the material guiding channel is connected to the material placement cavity. The inlet of the converging material guiding channel is larger than the outlet. The larger inlet stably receives the inner package, and the outlet is aligned with the corresponding material placement cavity to ensure that the inner package falls stably into the material placement cavity.

[0017] Preferably, the suction robot is a suction cup type or a magnetic suction type. The suction-type robot ensures that the inner package does not deform.

[0018] Preferably, the wing-type moxibustion patch laminating equipment includes an adhesive application mechanism, which comprises a guide roller, an adhesive dispensing component, and a telescopic transmission component. The adhesive dispensing component is positioned opposite to the guide roller that pulls the bottom layer of material. The adhesive dispensing component has an operating state and a standby state. When the adhesive dispensing component is in the operating state, the telescopic transmission component drives the adhesive dispensing component to approach the guide roller to apply adhesive to the bottom layer of material. When the adhesive dispensing component is in the standby state, the telescopic transmission component drives the adhesive dispensing component away from the guide roller. The contact between the adhesive dispensing component and the bottom layer of material driven by the telescopic transmission component allows for adhesive application to bottom layer materials without adhesive properties. When the adhesive dispensing component is driven away from the bottom layer of material by the telescopic transmission component, the dispensing component stops working, allowing the wing-type moxibustion patch laminating equipment to adapt to bottom layer materials with inherent adhesiveness. The adhesive application mechanism enables the wing-type moxibustion patch laminating equipment to adapt to different types of bottom layer materials. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0031] See Figure 1 and Figure 2 A production line for wing-shaped moxibustion patches includes an inner packaging forming device 1 and a wing-shaped moxibustion patch composite device 2. A variable-speed conveyor belt 3 and an equally spaced conveyor mechanism A connect the inner packaging forming device 1 and the wing-shaped moxibustion patch composite device 2. Figure 3 As shown, the feed end of the variable speed conveyor belt 3 is connected to the discharge end of the inner packaging forming device 1, the discharge end of the variable speed conveyor belt 3 is connected to the feed end of the equal spacing conveyor mechanism A, and the discharge end of the equal spacing conveyor mechanism A is connected to the feed end of the wing-type moxibustion patch composite device 2.

[0032] The equal-spacing conveying mechanism A includes an integrated conveying component 4 and a speed adjustment component 5. The integrated conveying component 4 includes a main conveyor belt 41 and an auxiliary conveyor belt 42 arranged in parallel. Both the main conveyor belt 41 and the auxiliary conveyor belt 42 are equipped with push blocks 43 arranged longitudinally at equal intervals. The push blocks 43 push the inner package to initially adjust the front and rear spacing of the inner packages with different spacings. There is a material placement cavity between adjacent push blocks 43. The main conveyor belt 41 and the auxiliary conveyor belt 42 have infeed positions for receiving inner packages. The speed adjustment conveyor belt 3 stably delivers the inner package to the material placement cavity at the infeed position by adjusting its own conveying speed, so as to achieve stable online operation of the equipment.

[0033] When the main conveyor belt 41 receives the inner packages sent out by the variable speed conveyor belt 3, there are empty material placement cavities between the inner packages. Due to production limitations, the inner package forming equipment usually sends out inner packages in groups, with a certain distance between each group of inner packages. This distance causes empty material placement cavities to be created on the main conveyor belt when the inner packages enter. In order to fill all the material placement cavities on the main conveyor belt with inner packages and achieve continuous conveying, the auxiliary conveyor belt 42 uses a suction robot 44 to transfer its inner packages to the empty material placement cavities on the main conveyor belt 41 for inner package integration, so that the inner packages sent out by the main conveyor belt 41 are arranged longitudinally at intervals. The main conveyor belt 41 and the auxiliary conveyor belt 42 are connected by the suction robot 44. The above integration refers to the suction robot 44 being used to transfer the inner packages of the auxiliary conveyor belt 42 to the main conveyor belt 41, and to make the inner packages in the main conveyor belt 41 arranged in a single longitudinal row (as shown in the attached figure). Figure 6 As shown, this ensures the continuity of production between the inner packaging forming equipment 1 and the wing-type moxibustion patch composite equipment 2. The discharge end of the main conveyor belt 41 is connected to the input end of the speed adjustment component 5. The suction robot ensures that the arrangement of the inner packages meets the feeding requirements of the wing-type moxibustion patch composite equipment 2, thereby achieving production matching between the inner packaging forming equipment 1 and the wing-type moxibustion patch composite equipment 2, and ensuring that the production speed and capacity are compatible.

[0034] In addition, there are various types of contents in the inner packaging, which are basically divided into inner packaging containing iron powder and inner packaging without iron powder. For inner packaging without iron powder, the preferred material suction robot is a suction cup type; for inner packaging containing iron powder, the preferred material suction robot is a magnetic suction type. The inner packaging is transferred by adsorption, avoiding compression and ensuring that the inner packaging is flat.

[0035] To ensure the inner packaging is positioned correctly and spaced evenly when inserted into the wing-shaped moxibustion patch device, see [link / reference]. Figure 4The speed adjustment assembly 5 includes a correction unit 51 and a spacing adjustment unit 52. The correction unit 51 includes a stationary material support plane and a correction push plate 512. To facilitate the adjustment of the inner package's posture before entering the spacing adjustment unit 52, a stationary material support plane is provided between the main conveyor belt 41 and the spacing adjustment unit 52. This allows the inner package to enter the spacing adjustment unit 52 with the correct posture, and the stationary material support plane can reduce the conveying speed of the inner package placed on it, shortening the spacing between adjacent inner packages. There are various forms of stationary material support plane configuration, such as the stationary material support plane being located on a pallet 511, which is fixedly positioned between the main conveyor belt 41 and the front and rear sway units. The push block 43 has a small contact area with the material, therefore, the push block 43 easily causes the material edges to curl upwards during the pushing process, causing the material to gradually shift during movement, affecting the yield. To ensure the material remains upright, a correction pusher plate 512 is installed above the stationary material support plane. The correction pusher plate 512 increases the contact area with the material edge, ensuring uniform force distribution and preventing material deviation during movement. During the pushing process, the correction pusher plate 512 also corrects the material's posture, ensuring the material enters the variable-speed conveyor plane upright and guaranteeing a high yield. The correction pusher plate 512 has a pushing plane perpendicular to the stationary material support plane. The correction pusher plate 512 can be perpendicular to the stationary material support plane in its initial state or during the pushing process.

[0036] To ensure that the correction push plate 512 contacts the edge of the inner package, a pushing gap is provided on the support plate 511 for the correction push plate 512 to partially extend into and move horizontally. The correction push plate 512 pushes the inner package on the stationary support plane into the spacing adjustment unit 52. The correction push plate 512 is connected to the pushing drive mechanism 6. In this embodiment, the pushing drive mechanism 6 includes a lifting drive component 61 and a lateral drive component 62. The lifting drive component 61 drives the correction push plate 512 to move up and down, and the lateral drive component 62 drives the correction component to move horizontally. Specifically, the lifting drive component 61 is mounted on the frame, and its output end is connected to the lifting base. The lateral drive component 62 is fixedly mounted on the lifting base, and its output end is connected to the correction push plate 512. The lifting drive component 61 drives the lifting base to move the correction push plate 512 up and down, causing part of the correction push plate 512 to extend into the material pushing gap, ensuring stable contact between the correction push plate 512 and the inner edge. The lateral drive component 62 drives the correction push plate 512 to move horizontally, realizing the material pushing action. The power source for both the lateral drive component 62 and the lifting drive component 61 is preferably a servo motor.

[0037] Because the inner packaging edges are relatively soft and prone to warping under pressure, a pressure plate 8 is provided on the correction push plate to further ensure the inner packaging enters the moxibustion patch composite device smoothly. The pressure plate 8 is positioned vertically opposite to the stationary material support plane. Specifically, the pressure plate 8 is fixedly mounted on the correction push plate. As the correction push plate moves downward, the pressure plate 8 flattens the inner packaging, ensuring its flatness. The pressure plate 8 can be inclined along the inner packaging conveying direction, with the front higher than the back, or it can be parallel to the stationary material support plane.

[0038] See Figure 5 The spacing adjustment unit 52 includes a variable speed conveying plane. By controlling the conveying speed of the variable speed conveying plane, the inner package is conveyed at equal intervals after entering the wing-type moxibustion patch composite device 2. By adjusting the conveying speed of the variable speed conveying plane, the position of the inner package when entering the wing-type moxibustion patch composite device 2 is controlled, thereby ensuring that the spacing between adjacent inner packages is consistent and ensuring the yield of the wing-type moxibustion patch composite device 2.

[0039] The following optimizations or further explanations can be made based on the above embodiments.

[0040] For example, the spacing adjustment unit 52 further includes an alignment conveying component 521, a variable speed drive motor 522, a position sensor 523, and a controller. The variable speed conveying plane is formed on the alignment conveying component 521. The variable speed drive motor 522 is connected to the alignment conveying component 521 for adjusting the conveying speed of the alignment conveying component 521. The position sensor 523 is used to detect the actual position of the inner package on the variable speed conveying plane. The position sensor 523 is mounted on the frame relative to the variable speed conveying plane. The controller is electrically connected to both the position sensor 523 and the variable speed drive motor 522. The controller controls the output speed of the variable speed drive motor 522 based on the deviation between the actual distance and the set distance between the inner package position signal and the set position, thereby achieving equidistant conveying of the inner package after it enters the wing-type moxibustion patch composite device 2. The target position can be manually set or a fixed position set by other methods. Setting the target position is a conventional technique used by those skilled in the art and will not be elaborated further here. The set distance is between the set position and the expected position of the inner package. The actual distance between the actual position of the inner package and the set position is transmitted by the position sensor 523. When the actual distance is greater than the set distance, the controller controls the variable speed drive motor 522 to drive the variable speed conveying plane to increase the conveying speed accordingly. If the actual distance is less than the original distance, the controller controls the variable speed drive motor 522 to drive the variable speed conveying plane to decrease the conveying speed accordingly.

[0041] The alignment conveying assembly 521 includes a first synchronous belt 521a and a second synchronous belt 521b that operate synchronously. The first synchronous belt 521a and the second synchronous belt 521b are arranged vertically opposite each other, and the variable speed conveying plane is formed between the first synchronous belt 521a and the second synchronous belt 521b. The first synchronous belt 521a is disposed on a first drive shaft and a first driven shaft, which are arranged parallel to each other in the horizontal direction. A first main synchronous pulley is fixedly disposed on the first drive shaft, and a first passive synchronous pulley is fixedly disposed on the first driven shaft. The first synchronous belt 521a is wound between the first main synchronous pulley and the first passive synchronous pulley. The second synchronous belt 521b is disposed on a second drive shaft and a second driven shaft, which are arranged parallel to each other in the horizontal direction. A second main synchronous pulley is fixedly disposed on the second drive shaft, and a second passive synchronous pulley is fixedly disposed on the second driven shaft. The second synchronous belt 521b is wound between the second main synchronous pulley and the second passive synchronous pulley. The horizontal parallel arrangement of the drive shaft and the driven shaft can increase the length of the variable speed conveying plane to ensure that the inner package has sufficient time to accelerate or decelerate. In addition, the powder inside the inner package may be uneven during production and pushing by the pusher block 43, resulting in uneven thickness of the inner package. When the correction pusher plate 512 pushes the inner package into the variable speed conveying plane, the first drive shaft of the first synchronous belt 521a and the second drive shaft of the second synchronous belt 521b cooperate to clamp and flatten the inner package, so as to prevent the inner package from swaying during the conveying process of the variable speed conveying plane.

[0042] For example, the correction pusher plate 512 is connected to the material pushing drive mechanism 6, and the material pushing drive mechanism 6 is electrically connected to the controller. The variable speed conveying plane includes an initial first speed and a second speed determined by a signal sent by the position sensor 523. The first speed is the initial speed of the material before it enters the variable speed conveying plane, and the second speed is an increase or decrease of the first speed. The controller controls the material pushing drive mechanism 6 to drive the correction pusher plate 512 to match the first speed. The correction pusher plate 512 pushes the material forward at the first speed, so that the speed difference between the two when the material enters the variable speed conveying plane is reduced or even zero, avoiding slippage or displacement of the material due to sudden acceleration or deceleration, and further improving the yield. After receiving the signal of the material arriving on the variable speed conveying plane, the position sensor 523 sends a command to the variable speed drive motor 522 through the controller to realize the speed change of the variable speed conveying plane at the second speed. The position sensor 523 senses the material that has entered the variable speed conveying plane, and the controller controls the variable speed drive motor 522 to stably drive the material out at the changing second speed to ensure that the material is arranged at equal intervals on the bottom roll.

[0043] For example, there are various implementations of the suction robot 44, such as a three-axis suction robot, or as in this embodiment, the suction robot includes a suction element and a transmission assembly. The transmission assembly includes a mounting base, a transverse frame, and a longitudinal moving seat. The mounting base is used for mounting the suction element. The mounting base is connected to the lifting and transferring drive component. The lifting and transferring drive component is fixedly mounted on the transverse frame. The transverse frame is connected to the transverse drive component. The transverse drive component is fixedly mounted on the longitudinal moving seat. The longitudinal moving seat is slidably mounted on the frame and is connected to the longitudinal transferring drive component. The transmission assembly drives the suction element to move in three directions: up and down, transverse and longitudinal, to transfer the inner package of the auxiliary conveyor belt 42 into the main conveyor belt 41.

[0044] For example, the variable speed conveyor belt 3 is equipped with a sensor 32 for detecting the position of the inner package at the inlet end. The variable speed conveyor belt 3 is positioned above the integrated conveyor assembly 4, which is connected to the second servo motor. The position of the inner package received by the integrated conveyor assembly 4 is the inner package inlet position. The time interval between the push block passing the inlet position is stable. Based on the inner package position signal from the position sensor 32, the controller can predict the time when the inner package will arrive at the inlet position and compare it with the time when the push block is about to arrive. The controller then adjusts the conveying speed of the variable speed conveyor belt 3 to make the inner package fall into the placement chamber, ensuring that the inner package enters the equally spaced conveyor mechanism A continuously and accurately.

[0045] To ensure the inner package falls more stably into the feeding chamber, see [link / reference]. Figure 3 The discharge end of the variable speed conveyor belt 3 is equipped with a guide plate assembly 31. The guide plate assembly 31 has a converging guide channel 311, the number of which matches the number of inner packages. The outlet of the guide channel 311 is connected to the material placement cavity. The guide plate assembly 31 prevents the inner packages from shifting laterally. In addition, the outlet of the guide channel is connected to the inlet of the material placement cavity, thereby ensuring that the inner packages fall stably into the guide channel.

[0046] See Figures 7-8The wing-type moxibustion patch laminating equipment includes a bottom layer unwinding mechanism, a release paper unwinding mechanism, a traction mechanism, and a rotatable roller cutter. The bottom layer unwinding mechanism supplies the bottom layer material, the release paper unwinding mechanism unwinds the release paper, the traction mechanism laminates the bottom layer material and release paper, and the roller cutter cuts the laminated material. The bottom layer unwinding mechanism, release paper unwinding mechanism, traction mechanism, and roller cutter are mature technologies and will not be described in detail here. The bottom layer material is divided into two types: non-adhesive (such as non-woven fabric) and adhesive (such as elastic tape). To adapt the wing-type moxibustion patch laminating equipment to different bottom layer materials, the equipment includes an adhesive application mechanism 9. After unwinding, the bottom layer material passes through the adhesive application mechanism before being laminated with the inner packaging and release paper. The gluing mechanism 9 includes a guide roller 92, a glue dispensing component 91, and a telescopic transmission component. The glue dispensing component 91 is positioned opposite to the guide roller 92, which pulls the bottom layer roll. The bottom layer roll passes between the glue dispensing component 91 and the guide roller 92. The glue dispensing component 91 has a working state and a standby state. When the glue dispensing component 91 is in the working state, the telescopic transmission component drives the glue dispensing component 91 closer to the guide roller 92 to apply glue to the bottom layer roll. When the glue dispensing component 91 is in the standby state, the telescopic transmission component drives the glue dispensing component 91 away from the guide roller 92. When the bottom layer roll is non-adhesive, such as non-woven fabric, the telescopic transmission component drives the glue dispensing component 91 closer to the guide roller 92 to apply glue. When the bottom layer roll is an adhesive elastic fabric, the telescopic transmission component drives the glue dispensing component 91 away from the guide roller 92, and the dispensing port does not contact the bottom layer roll, so that the glue dispensing component 91 is in the standby state and does not participate in the operation. This allows the wing-type hot compress patch composite device of the present invention to adapt to different types of bottom layer rolls. The telescopic transmission component includes a movable seat and a cylinder or servo motor that drives the movable seat to move horizontally. A guide rod is provided on the frame, and the axis of the guide rod is set in the horizontal direction. The movable seat is sleeved on the guide rod. The glue dispensing component 91 is fixedly set on the movable seat. The cylinder or servo motor drives the movable seat to move horizontally on the guide rod. Of course, other existing linear drive structures can also be used for the telescopic transmission component.

[0047] The working principle of the present invention is described below with reference to the accompanying drawings:

[0048] The inner packaging forming equipment 1 delivers multiple rows of inner packages, which are then fed one row at a time onto the variable speed conveyor belt 3. The controller controls the variable speed conveyor belt 3 to accelerate or decelerate based on the inner package position signal from the position sensor 32, so that the inner packages enter the corresponding material placement chambers of the main conveyor belt 41 and the auxiliary conveyor belt 42. Subsequently, the suction robot 44 picks up the inner packages from the auxiliary conveyor belt 42 and transfers them to the main conveyor belt 41 in a single row, thus meeting the input requirements of the wing-type moxibustion patch composite equipment.

[0049] The inner package is then conveyed by the main conveyor belt 41 to the stationary material support plane of the pallet 511. The correction push plate 512 moves down, and during the downward movement, the pressure plate 8 flattens the inner package. The correction push plate 512 then moves horizontally to contact the rear edge of the inner package and pushes the inner package onto the variable speed conveyor plane. The position sensor detects the actual position of the inner package entering the variable speed conveyor plane and sends the actual position signal of the inner package to the controller. The controller controls the variable speed drive motor 522 to drive the first synchronous belt 521a and the second synchronous belt 521b to accelerate or decelerate synchronously (i.e., adjust the speed of the variable speed conveyor plane) based on the deviation between the actual position signal of the inner package detected by the position sensor and the target position. This adjusts the position of the inner package entering the wing-type moxibustion patch composite equipment 2, thereby achieving the goal of equidistant arrangement of the inner packages after entering the wing-type moxibustion patch composite equipment 2, meeting the production requirements of the wing-type moxibustion patch composite equipment 2, and realizing the connection between the inner package forming equipment 1 and the wing-type moxibustion patch composite equipment 2.

[0050] Before the production line for wing-type moxibustion patches starts operating, the working state of the adhesive components can be selected according to the type of the bottom roll material, so that the production line can adapt to different types of bottom roll materials.
