Description

Technical Field

[0001] This application relates to the field of cosmetic production equipment technology, and more particularly to an extrusion device. Background Technology

[0002] In the cosmetic production process, raw materials need to be added to a raw material adding machine. When adding raw materials, the raw materials in the packaging bag are usually transferred to the raw material adding machine by manual squeezing. Most of the raw materials are currently packaged in flexible and elastic plastic packaging bags. When manually squeezing the packaging bag, it is difficult to form a uniform and continuous pressure on the entire bag, which results in the raw materials in some areas of the packaging bag not being squeezed out evenly, leading to a large amount of raw materials remaining in the plastic packaging bag and causing raw material waste. Summary of the Invention

The length direction of the active roller is parallel to the length direction of the driven roller. A first preset distance is provided between the active roller and the driven roller to form an extrusion channel.

[0007] The driving roller shaft is equipped with a first gear, and the driven roller shaft is equipped with a second gear, with the first gear and the second gear meshing together.

[0008] The output end of the drive motor is connected to the active roller shaft through a transmission component; so that when the drive motor drives the active roller shaft to rotate, it synchronously drives the driven roller shaft to rotate in the opposite direction, thereby making the active roller shaft and the driven roller shaft evenly squeeze the packaging bag and drive it through the squeezing channel.

[0009] In one possible implementation, the transmission components include: a driving wheel, a driven wheel, and a transmission chain; one end of the driving roller passes through a fixed block and is connected to the driven wheel, the driving wheel is installed at the output end of the drive motor, and the transmission chain is sleeved on the driven wheel and the driving wheel.

[0011] In one possible implementation, an adjusting bolt and a spring are also included; a sliding groove is provided on the fixed block, a second bearing is embedded in the sliding groove, and the spring is located in the sliding groove and between the first bearing and the second bearing; a threaded hole is provided on the top of the fixed block, and the threaded hole is connected to the sliding groove, and one end of the adjusting bolt passes through the threaded hole and is inserted into the sliding groove.

[0012] In one possible implementation, protective barriers are also included; two protective barriers are mounted on a fixed block and located at the entrance of the extrusion channel, the length directions of the two protective barriers are parallel to each other, and a second preset distance is provided between the two protective barriers.

[0013] In one possible implementation, a scraper is also included; the scraper is detachably mounted on the mounting frame, the length direction of the scraper is parallel to the length direction of the drive roller, and the scraper abuts against the side wall of the drive roller.

[0014] In one possible implementation, a receiving device is provided below the extrusion assembly, the receiving device including a funnel and a collecting trough; the funnel is fixedly mounted on the mounting frame, and the funnel's self-supporting interface gradually decreases in size in the direction away from the extrusion assembly, and the collecting trough is placed on the mounting frame and located at the discharge port below the funnel.

[0015] In one possible implementation, a cover plate is also included; the cover plate is detachably fastened to the receiving interface of the funnel.

[0016] In one possible implementation, a hook is provided on one side of the mounting bracket; the cover plate has hanging holes that match the hooks, and the cover plate is detachably hung on the hooks.

[0017] In one possible implementation, a controller is also included, which is located on one side of the mounting bracket, and the output of the controller is electrically connected to the input of the drive motor.

[0018] Beneficial effects of this application

[0019] When the drive motor drives the active roller to rotate, the first gear rotates accordingly. Through the meshing of the first and second gears, the driven roller rotates synchronously in opposite directions. The operator places the packaging bag containing cosmetic raw materials at the entrance of the extrusion channel. As the active and driven rollers rotate synchronously in opposite directions, their surfaces come into contact with the packaging bag and generate friction, driving the packaging bag through the extrusion channel. At the same time, the active and driven rollers uniformly and continuously extrude the packaging bag through the extrusion channel. The raw materials extruded from the packaging bag fall directly into the receiving device below under the action of gravity.

[0020] This application, by setting up a bag-squeezing assembly with a first preset distance between the active and driven rollers and a gear meshing connection, enables the drive motor to drive the active roller to rotate, and achieves synchronous and opposite rotation of the active and driven rollers through gear transmission. When the packaging bag passes through the extrusion channel, the active and driven rollers apply uniform and continuous extrusion force to the packaging bag, thereby uniformly extruding the raw material inside the packaging bag. This avoids the raw material residue in the packaging bag caused by uneven force in manual extrusion, reducing the amount of raw material residue in the packaging bag, avoiding material waste, and improving the extrusion effect. The extrusion device of this application has a simple and compact structure, is easy and convenient to operate, and can realize the extrusion operation of the packaging bag by driving the bag-squeezing assembly with a drive motor, reducing the labor intensity of manual operation and improving production efficiency.

[0032] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0033] This application proposes an extrusion device, such as Figures 1 to 3As shown, the assembly includes: a mounting frame 100, a bag extrusion assembly 200, and a drive motor 300; both the bag extrusion assembly 200 and the drive motor 300 are mounted on the mounting frame 100; the bag extrusion assembly 200 includes: a drive roller 210, a driven roller 220, and a fixing block 230; the fixing block 230 is disposed opposite to each other on the top of the mounting frame 100, and the drive roller 210 and the driven roller 220 are rotatably disposed on the fixing block 230, with the length direction of the drive roller 210 and the length direction of the driven roller 220 being parallel to each other; and the drive roller 210 and the driven roller 220 are parallel to each other. A preset distance is provided between the rotating rollers 220 to form a compression channel; a first gear 211 is provided on the driving roller 210, and a second gear 221 is provided on the driven roller 220, with the first gear 211 and the second gear 221 meshing together; the output end of the drive motor 300 is connected to the driving roller 210 through a transmission component 400; so that when the drive motor 300 drives the driving roller 210 to rotate, it synchronously drives the driven roller 220 to rotate synchronously in opposite directions; the driving roller 210 and the driven roller 220 uniformly compress the packaging bag and drive it through the compression channel.

[0034] It should be noted that the mounting bracket 100 provides a mounting foundation for the overall equipment; the fixing block 230 provides reliable support for the drive roller 210 and driven roller 220, ensuring the stability of their relative positions and preventing tilting or changes in spacing that could cause jamming during bag compression. The ends of the drive roller 210 and driven roller 220 are rotatably mounted on the fixing block 230 and positioned between the two blocks. The parallel design of the drive roller 210 and driven roller 220 ensures a consistent distance between them, guaranteeing uniform pressure on the bag as it passes through the compression channel, thus preventing... In cases of localized over- or under-compression during the extrusion of the packaging bag, the system ensures that the raw material is evenly extruded from the bag. A reasonable preset distance ensures that the packaging bag can pass smoothly through the extrusion channel while being subjected to appropriate extrusion force. The meshing connection between the first gear 211 and the second gear 221 enables synchronous, opposite-direction rotation of the drive roller 210 and the driven roller 220. The drive motor 300 provides rotational power to the drive roller 210, and the transmission component 400 transmits the power output from the drive motor 300 to the drive roller, thereby driving the drive roller 210 to rotate. Simultaneously, the rotational power of the drive roller 210 drives the driven roller 220 to rotate synchronously and opposite-direction through the meshing transmission of the first gear 211 and the second gear 221, thus achieving the extrusion and conveying of the packaging bag.

[0035] When the drive motor 300 drives the active roller 210 to rotate, the first gear 211 rotates accordingly. Through the meshing of the first gear 211 and the second gear 221, the driven roller 220 is driven to rotate synchronously in opposite directions. The operator places the packaging bag containing cosmetic raw materials at the entrance of the extrusion channel. As the active roller 210 and the driven roller 220 rotate synchronously in opposite directions, the surfaces of the active roller 210 and the driven roller 220 come into contact with the packaging bag and generate friction, which drives the packaging bag through the extrusion channel. At the same time, the active roller 210 and the driven roller 220 uniformly extrude the packaging bag through the extrusion channel. The raw materials extruded from the packaging bag fall directly into the receiving device below under the action of gravity.

[0036] This application, by setting up a bag extrusion assembly 200, with a first preset distance between the active roller 210 and the driven roller 220 and connected by gear meshing, enables the drive motor 300 to drive the active roller 210 to rotate. The synchronous, opposite-direction rotation of the active roller 210 and the driven roller 220 is achieved through gear transmission. When the packaging bag passes through the extrusion channel, the active roller 210 and the driven roller 220 apply uniform and continuous extrusion force to the packaging bag, thereby uniformly extruding the raw material inside the packaging bag. This avoids the material residue inside the packaging bag caused by uneven force in manual extrusion, reducing the amount of residual material and preventing material waste, thus improving the extrusion effect. The extrusion device of this application has a simple and compact structure, is easy and convenient to operate, and the extrusion operation of the packaging bag can be achieved by driving the bag extrusion assembly 200 with the drive motor 300, reducing the labor intensity of manual operation and improving production efficiency.

[0037] In one possible implementation, the transmission component 400 includes: a drive wheel 410, a driven wheel 420, and a transmission chain 430; one end of the drive roller 210 passes through the fixing block 230 and is connected to the driven wheel 420; the drive wheel 410 is installed at the output end of the drive motor 300; and the transmission chain 430 is sleeved on the driven wheel 420 and the drive wheel 410. It should be noted that the drive wheel 410 is installed at the output end of the drive motor 300 and is suitable for transmitting the power output by the drive motor 300 to the transmission chain 430. The transmission chain 430 is suitable for transmitting the power on the drive wheel 410 to the driven wheel 420. The driven wheel 420 is installed at one end of the drive roller 210 and receives the power from the drive wheel 410 through the transmission chain 430, thereby driving the drive roller 210 to rotate. The transmission chain 430 achieves smooth power transmission, reduces slippage during power transmission, ensures that the drive roller 210 obtains continuous and stable power, and ensures the smooth operation of the extrusion device.

[0038] In one possible implementation, the transmission component 400 can be connected by meshing of the driving wheel 410 and the driven wheel 420, or by a belt connecting the driving wheel 410 and the driven wheel 420.

[0039] In one possible implementation, the drive motor 300 can be an existing servo motor.

[0040] In one possible implementation, the fixed block 230 is provided with a first bearing (not shown) and a second bearing (not shown); the first bearing is fixedly mounted on the fixed block 230, and the drive roller shaft 210 is connected to the first bearing; the second bearing is slidably mounted on the fixed block 230, and the second bearing is located on the side of the first bearing away from the mounting bracket 100, and the driven roller shaft 220 is connected to the second bearing.

[0041] It should be noted that the first bearing provides a stable rotational support point for the drive roller 210. The first bearing is fixedly mounted on the fixed block 230, and the drive roller 210 is rotatably mounted on the fixed block 230 via the first bearing. The second bearing provides a rotational fulcrum for the driven roller 220, which is connected to the fixed block 230 via the second bearing. By sliding the second bearing, the distance between the driven roller 220 and the drive roller 210 can be adjusted, thereby changing the width of the extrusion channel and allowing the extrusion device to adapt to packaging bags of different thicknesses. The design of the first and second bearings reduces the frictional resistance between the drive roller 210 and the driven roller 220 and the fixed block 230 during rotation, making the rotation of the drive roller 210 and the driven roller 220 smoother, reducing energy loss, and improving transmission efficiency.

[0042] Furthermore, both the first and second bearings are 6003RS bearings.

[0043] In one possible implementation, an adjusting bolt 240 and a spring (not shown in the figure) are also included; a sliding groove 231 is provided on the fixing block 230, the second bearing is embedded in the sliding groove 231, and the spring is provided in the sliding groove 231 and located between the first bearing and the second bearing; a threaded hole is provided on the top of the fixing block 230, and the threaded hole is connected to the sliding groove 231, and one end of the adjusting bolt 240 is inserted into the sliding groove 231 through the threaded hole.

[0044] It should be noted that the sliding groove 231 is used to guide the second bearing, ensuring that the second bearing slides smoothly in a predetermined direction. The sliding groove 231 extends along the length of the sliding block. The second bearing is slidably disposed within the sliding groove 231. The adjusting bolt 240 is used to adjust the position of the second bearing within the sliding groove 231, thereby changing the distance between the drive roller shaft 210 and the driven roller shaft 220 (i.e., the width of the extrusion channel). The adjusting bolt 240 is threadedly connected to a threaded hole. By rotating the adjusting bolt 240, it screws in and out of the threaded hole, thus changing the position of the adjusting bolt 240 within the sliding groove 231. The length of the roller shaft 210 is adjusted to drive the second bearing to slide within the sliding groove 231, thereby adjusting the distance between the active roller shaft 210 and the driven roller shaft 220 (i.e., the width of the extrusion channel). The spring is set within the sliding groove 231, with its two ends connected to the inner wall of the sliding groove 231 and the outer wall of the second bearing, respectively. The elastic force of the spring enables the driven roller shaft 220 to adapt to changes in the thickness of the packaging bag within a certain range. When the thickness of the packaging bag is uneven, the spring can push the second bearing and the driven roller shaft 220 to automatically fine-tune their positions, thereby ensuring that the second roller shaft always maintains stable extrusion of the packaging bag, ensuring consistent extrusion effect, and improving product quality. It should be noted that the first preset distance between the driven roller shaft 220 and the driving roller shaft 210 is always less than the height of the teeth of the second gear 221. This ensures that, under the action of the spring elastic force and the adjustment bolt 240, the first gear 211 on the driven roller shaft 220 and the second gear 221 on the driving roller shaft 210 are always in meshing state. This avoids the failure of meshing between the first gear 211 and the second gear 221 or jamming due to changes in the first preset distance, thus ensuring the stability and reliability of the bag extrusion assembly 200.

[0045] In one possible implementation, the first preset distance (i.e., the distance between the drive roller 210 and the driven roller 220) is in the range of 0.5mm to 1.0mm.

[0046] In one possible implementation, the outer walls of both the drive roller 210 and the driven roller 220 are provided with roller grooves. During the extrusion process, the roller grooves generate a certain kneading effect on the surface of the packaging bag, making it easier for the material inside the packaging bag to be squeezed out and reducing the residue of raw materials inside the packaging bag. At the same time, the roller grooves can significantly increase the friction between the drive roller 210 and the driven roller 220 and the packaging bag, preventing the packaging bag from slipping or stopping during the extrusion process and ensuring that the packaging bag passes smoothly through the extrusion channel.

[0047] In one possible implementation, protective barriers 510 are also included; two protective barriers 510 are mounted on the fixed block 230 and located at the entrance of the extrusion channel, the length directions of the two protective barriers 510 are parallel to each other, and a second preset distance is provided between the two protective barriers 510.

[0048] It should be noted that the main body of the protective barrier 510 is a long rectangular structure. Both ends of the protective barrier 510 are connected to the fixing block 230 by bolts. The two protective barriers 510 are arranged parallel to each other at the entrance of the extrusion channel, forming a second preset distance between them. This second preset distance is less than the thickness of an adult's finger and matches the width of the extrusion channel, effectively preventing operators from accidentally inserting their fingers into the extrusion channel when placing packaging bags, and avoiding injury from being caught in the rotating drive roller 210 and driven roller 220 shafts, thus providing reliable safety protection for operators. Simultaneously, the center line of the second preset distance is parallel to the center line of the extrusion channel, ensuring that the packaging bag, guided by the protective barrier 510, can accurately and smoothly enter the extrusion channel, improving the stability and safety of the extrusion device during operation.

[0049] In one possible implementation, a scraper 520 is also included; the scraper 520 is detachably mounted on the mounting frame 100, the length direction of the scraper 520 is parallel to the length direction of the drive roller 210, and the scraper 520 abuts against the side wall of the drive roller 210; when the end of the packaging bag is squeezed, the raw material inside the packaging bag adheres to the surface of the drive roller 210, and the scraper 520 continuously abuts against the side wall of the roller, thereby scraping off the raw material adhering to the surface of the drive roller 210, thereby ensuring that the surface of the drive roller 210 is clean, reducing the wear of the drive roller 210 caused by raw material residue, and extending the service life of the bag extrusion assembly 200.

[0050] Furthermore, the scraper 520 includes a support arm and a scraper strip. The fixing block 230 is provided with fixing ears. Correspondingly, the two ends of the support arm are fixedly provided with screws, which pass through the fixing ears. Nuts are sleeved on the screws and threadedly connected to the screws. The scraper strip is fixedly provided on the support arm and extends along the length of the support arm. The scraper strip abuts against the drive roller 210, thereby scraping off the raw material on the drive roller 210.

[0051] Furthermore, the scraper is made of an elastic material.

[0052] In one possible implementation, a receiving device is provided below the extrusion assembly, the receiving device including a funnel 610 and a collection trough 620; the funnel 610 is fixedly mounted on the mounting frame 100, and the funnel 610 gradually decreases in size from the self-supporting interface toward the direction away from the extrusion bag assembly 200, and the collection trough 620 is placed on the mounting frame 100 and located at the discharge port below the funnel 610. It should be noted that the material receiving device is suitable for collecting raw materials squeezed out of the packaging bag to prevent spillage and waste. The main body of the funnel 610 has a pyramidal structure. The wide-diameter receiving port of the funnel 610 can cover the entire area below the extrusion bag assembly 200, ensuring that all materials can be caught. Then, guided by the conical inner wall, the materials converge to the narrow-mouthed discharge port. The mounting frame 100 is equipped with a placement plate 640, which is located below the funnel 610. The collection trough 620 is placed on the placement plate 640 and is located below the discharge port of the funnel 610, directly receiving the contents discharged from the funnel 610 to achieve temporary storage of materials.

[0053] In one possible implementation, a cover plate 630 is also included; the cover plate 630 is detachably fastened to the receiving interface of the funnel 610; the cover plate 630 closes the receiving interface of the funnel 610 by fastening, thereby preventing external dust, impurities, water droplets, etc. from falling into the funnel 610. When working, the cover plate 630 is removed to allow the squeezed material to smoothly enter the funnel 610; when not working, the cover plate 630 is fastened for protection, flexibly responding to different production needs.

[0054] Furthermore, the cover plate 630 is provided with a handle 632. The design of the handle 632 makes it convenient for workers to fasten the cover plate 630 to the receiving interface of the funnel 610 or open the receiving interface of the funnel 610.

[0055] In one possible implementation, a hook 110 is provided on one side of the mounting bracket 100; a hanging hole 631 matching the hook 110 is provided on the cover plate 630, and the cover plate 630 is detachably hung on the hook 110; the cover plate 630 can be fixed by simply hanging it on the hook 110, and the cover plate 630 can be suspended and stored on the mounting bracket 100 without any additional operation, without occupying the ground or workbench area, and avoiding the situation where the cover plate 630 is lost or deformed due to random placement after disassembly.

[0056] In one possible implementation, a controller 700 is also included. The controller 700 is located on one side of the mounting bracket 100. The input terminal of the controller 700 is suitable for connecting to a 220V power supply, and the output terminal of the controller 700 is electrically connected to the input terminal of the drive motor 300. The controller 700 controls the forward and reverse rotation of the drive motor 300 to realize the squeezing and unloading operation of the bag extrusion assembly 200 on the packaging bag. When rotating forward, the drive roller 210 and the driven roller 220 roll the packaging bag in and extrude the material. When rotating in reverse, the blocked or residual packaging bag can be removed from the squeezing channel for easy cleaning or reloading.

[0057] Furthermore, the controller 700 uses the existing 3G3JI-AB007 rotary frequency inverter.

[0058] In one possible implementation, an indicator light 710 is also included. The indicator light 710 is mounted on the controller 700, and the output terminal of the controller 700 is electrically connected to the input terminal of the indicator light 710. The indicator light 710 includes a green LED and a red LED connected in parallel. When the controller 700 controls the drive motor 300 to rotate in the forward direction, the green LED forms a circuit with the controller 700, and the controller 700 and the red LED are disconnected. At this time, the indicator light 710 displays green. When the controller 700 controls the drive motor 300 to rotate in the reverse direction, the green LED forms a circuit with the controller 700, and the controller 700 and the red LED are connected. At this time, the indicator light 710 displays red. When the controller 700 stops controlling the drive motor 300, the controller 700, the green LED, and the red LED are all disconnected. At this time, the indicator light 710 is in a de-energized state.

[0059] In one possible implementation, the mounting bracket 100 is provided with casters at the four corners of its bottom. The casters can be omnidirectional casters in the prior art, which makes it easy to push or move the extrusion device of this application.
