Description

Technical Field

[0001] The present invention relates to the technical field related to food transportation, and particularly relates to a chocolate sauce production device and its production process. Background Art

[0002] The main raw materials of chocolate sauce include selected chocolate blocks, high-quality granulated sugar (or fine powdered sugar), high-quality milk powder (or fragrant fresh cream), and functional phospholipids, etc. The quality of these selected raw materials directly and profoundly affects the final taste and overall quality of the chocolate sauce.

[0003] In the traditional manufacturing process, the transportation of chocolate blocks mainly relies on an efficiently operating conveyor belt system. However, when the chocolate blocks are directly placed on the conveyor belt for transmission, an issue that cannot be ignored is that the chocolate is prone to sticking due to direct contact with the conveyor belt surface, and then leaving residues that are difficult to remove. These residues not only affect the cleanliness of the conveyor belt but may also contaminate the subsequent produced chocolate sauce.

[0004] To address this problem, the currently common treatment method is to use a special scraper to directly act on the conveyor belt surface in order to effectively remove the residual chocolate. Although this method alleviates the cleaning problem of the conveyor belt to a certain extent, it cannot be ignored that the manufacturing cost of the special conveyor belt used for food transportation is significantly higher than that of ordinary transmission conveyor belts. If relying on the scraper for cleaning in the long term, the frequent scraping action will undoubtedly accelerate the wear of the conveyor belt, thus greatly shortening its service life. This not only increases the replacement frequency of the conveyor belt but also indirectly leads to the cumulative increase in production costs, posing challenges to the overall production efficiency and cost control. Summary of the Invention

[0007] Furthermore, a receiving tray is placed on the base.

[0008] Furthermore, a limiting screw located above the upper sliding block is threadedly connected to the top of the outer side of the support seat.

[0009] Furthermore, a control arm is movably fixed on the side of the guide seat, and a start switch is fixed on the middle of the control arm.

[0010] Furthermore, a reset push spring sleeved on the outer side of the guide rod is installed between the guide seat and the support frame, an anti-dropping pull frame is fastened to the guide seat, and an anti-dropping ejector rod is fixedly installed on the side of the limiting support plate.

[0011] Furthermore, the first counterweight mechanism includes: a reset support is fastened to the support frame, and a rope seat and a cylinder seat are movably installed on the side of the reset support, a cylinder body is fixedly installed on the cylinder seat, and the rope seat is fixedly connected to the pull rope.

[0012] Furthermore, a piston is movably installed inside the cylinder body, and a top plug spring is connected between the piston and the cylinder body, a return push arm is tightly connected to the end of the piston, a reset slide located on one side of the return push arm is fixedly installed at the bottom of the support frame, a one-way air valve and an air release hole are provided in the piston, a switching arm is movably installed on the surface of the piston, an upper limit rod and a lower limit rod are fixedly installed on the side of the reset support, the upper limit rod is located directly above the lower limit rod, and the switching arm is located between the upper limit rod and the lower limit rod.

[0013] Furthermore, the second weight mechanism is a metal sphere.

[0014] A production process for chocolate sauce comprises the following steps:

[0015] S1. Use a conveyor belt to transport 80kg of chocolate chunks into a pot, heat and melt them for later use.

[0016] S2. Add the melted large pieces of chocolate to 70 kg of soybean oil, 110 kg of water, 22 kg of hydroxypropyl distarch phosphate, 9 kg of octenyl succinic anhydride starch sodium, 100 kg of maltitol, 20 kg of glycerin, 100 kg of malt syrup, 22 kg of trehalose, 6 kg of milk powder, 800 g of salt, 100 g of carrageenan, 100 g of xanthan gum, 2 kg of monoglyceride, 550 g of potassium sorbate, 3.5 kg of phospholipid, 1.3 kg of caramel pigment, and 120 g of chocolate brown. Put them into a vacuum emulsifying machine for mixing and stirring, heat the temperature to 70 °C for emulsification and homogenization, and then heat and gelatinize after homogenization is completed.

[0017] S3. After gelatinization, add 400 g of chocolate essence, 300 g of citric acid, and 50 g of vanillin, and stir and heat up to 100 °C for sterilization for ten minutes, and then vacuum package.

[0018] The present invention has the following beneficial effects:

[0019] A chocolate sauce production device and its production process provided by the present invention. The scraper can move directionally along the outside of the precisely processed support rod through a stable support seat. This design ensures the stability and accuracy of the scraper when performing the cleaning task.

[0020] When chocolate residues are inevitably adhered to the conveyor belt, as the conveyor belt continues to run, these residues will be guided to the working area of the scraper. At this time, the contact between the residues and the scraper will generate a certain driving force, prompting the scraper to move smoothly along the preset trajectory towards the direction of the guide seat. As the scraper moves, when it reaches the preset position and triggers the start switch, the coil is energized and quickly generates magnetism, generating a repulsive force with the magnetic block installed on the scraper. This magnetic repulsive force becomes the power source for driving the scraper to strongly scrape the chocolate residues on the conveyor belt. The scraping process is both efficient and thorough, ensuring the cleanliness of the conveyor belt, thereby guaranteeing the hygiene standards of subsequent chocolate sauce production.

[0021] After the scraping and cleaning task is completed, the electromagnetic system is powered off and the magnetic repulsive force disappears. At this time, under the action of its own gravity, the scraper automatically and smoothly returns to the initial position, ready to receive the next scraping signal. This automatic reset function not only improves the automation degree of the equipment, but also ensures the stability and reliability during the continuous production process.

[0022] In summary, the chocolate sauce production device realizes the timely scraping and cleaning effect of the conveyor belt through its innovative automatic cleaning mechanism. This design not only improves the production efficiency, but also ensures the product hygiene quality, providing a strong guarantee for the high-quality production of chocolate sauce.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Example 1. In the process of manufacturing chocolate sauce, the following method is mainly used:

[0035] Step 1: First, convey 80 kg of large chocolate pieces to the pot, heat and melt them for standby.

[0036] Step 2: Add the melted large chocolate pieces to 70 kg of soybean oil, 110 kg of water, 22 kg of hydroxypropyl distarch phosphate, 9 kg of octenyl succinic anhydride starch sodium, 100 kg of maltitol, 20 kg of glycerol, 100 kg of malt syrup, 22 kg of trehalose, 6 kg of milk powder, 800 g of salt, 100 g of carrageenan, 100 g of xanthan gum, 2 kg of monoglyceride, 550 g of potassium sorbate, 3.5 kg of phospholipid, 1.3 kg of caramel pigment, and 120 g of chocolate brown, put them into a vacuum emulsifier for mixing and stirring, heat the temperature to 70 °C for emulsification and homogenization, and then heat and gelatinize after homogenization is completed.

[0037] Step 3: After gelatinization, add 400 g of chocolate essence, 300 g of citric acid, and 50 g of vanillin, stir and heat up to 100 °C for sterilization for ten minutes, and then vacuum package.

[0038] For the conveying of large chocolate pieces, generally, the motor 3 is used to drive the conveyor belt 2 for conveying, as Figure 1 shown. The base 1 supports and fixes the conveyor belt 2 and the motor 3 to realize the smooth forward conveying of the large chocolate pieces in the clockwise direction on the surface of the conveyor belt 2. However, in the actual conveying process, since the chocolate is easy to stick to the conveyor belt 2, this causes some chocolate residues to firmly stick to the conveyor belt 2.

[0039] In order to remove the chocolate residues sticking to the conveyor belt 2, combined with Figure 1 and Figure 2 it can be seen that a support frame 5 for supporting the entire cleaning device is welded inside the base 1, and two symmetrically arranged guide rods 7 are installed on the side of the support frame 5, and the two ends of the guide seat 6 are fixedly connected to the ends of the guide rods 7. Combined with Figure 2 , Figure 5 and Figure 7 it can be seen that support rods 18 are symmetrically fixed on the guide seat 6, both of the two support rods 18 are located above the guide rods 7, and the support rods 18 and the support frame 5 are sleeved together. The support seat 8 is sleeved on the support rods 18 to realize the reciprocating movement of the support seat 8 along the support rods 18 in a fixed direction. During actual assembly, balls can be provided at the connection part of the support seat 8 and the support rods 18 to reduce the friction between the two during the movement.

[0040] The outer side of the support seat 8 is movably installed with an upper slider 9 and a lower slider 13 that move up and down vertically along the support seat 8, asFigure 2 As shown in the figure, the upper slider 9 is located above the lower slider 13. A scraper 10 and an upper baffle 11 are fixedly connected to the outside of the upper slider 9 by bolts. A lower baffle 14 located below the upper baffle 11 is fixedly connected to the outside of the lower slider 13 by bolts. A pressure accumulator spring 15 is fixedly connected between the upper baffle 11 and the lower baffle 14. Under normal conditions, under the action of the self-gravity of the lower slider 13, the lower slider 13 moves along the support seat 8 to the lower limit. The pressure accumulator spring 15 can support the upper baffle 11, so that the scraper 10 is normally located below the conveyor belt 2. It should be noted that in this state, the scraper 10 is close to the conveyor belt 2, but the two do not contact, that is, the gap between the scraper 10 and the conveyor belt 2 is relatively small.

[0041] A pull rope 17 is fixedly installed on the support seat 8. The other end of the pull rope 17 passes through the lower baffle 14 and is connected to a weight mechanism, such as Figure 5 shown, the weight mechanism can be a metal sphere. As Figures 5 - 7 can be seen from the figure, a start switch 27 is installed on the guide seat 6. Correspondingly, a switch top block 801 for pressing the start switch 27 is fixedly connected to the side of the support seat 8. The shape of the switch top block 801 is mainly a cuboid. When the switch top block 801 abuts against the start switch 27, the start switch 27 will start to be turned on. The start switch 27 can energize the coil 29 fixed on the outside of the support seat 8 and generate a magnetic force repulsive to the magnet 28. Combining Figure 7 shown, for the fixation of the magnet 28, the limit support plate 16 is fixedly connected to the lower slider 13 by bolts. The magnet 28 is fixed on the limit support plate 16 and is located directly above the coil 29. When the coil 29 is energized and generates a magnetic force, the magnet 28 will have a tendency to drive the lower slider 13 to move upward.

[0042] In actual application, under normal conditions, under the traction of the weight mechanism, the pull rope 17 has a tendency to pull the support seat 8 away from the guide seat 6. At this time, the support seat 8 drives the switch top block 801 to move relatively away from the start switch 27, and the start switch 27 is not turned on, and the coil 29 connected to it will not work either. Under the traction of the pull rope 17, the lower baffle 14 will also have a tendency to move downward until the lower baffle 14 drives the lower slider 13 to move downward to the bottom limit. During this process, the pressure accumulator spring 15 supports the scraper 10 and the upper baffle 11, so that there is a small gap between the scraper 10 and the conveyor belt 2.

[0043] The motor 3 is used to rotate the conveyor belt 2 clockwise, so as to complete the conveying of the chocolate blocks. When there is chocolate residue adhered to the conveyor belt 2, the chocolate residue adhered to the conveyor belt 2 will first pass through the scraper 10. If the adhesion force of the residue is less than the force pushing the scraper 10 to move, it will be separated from the conveyor belt 2 under the scraping of the scraper 10 and fall on the receiving tray 4 placed on the base 1, so as to complete the collection of the residue.

[0044] If the adhesion strength of the chocolate residue is relatively large, it will push the scraper 10 to move towards the guide seat 6. When the switch top block 801 on the support seat 8 presses the start switch 27, the coil 29 will be energized and generate a magnetic force that repels the magnet 28. At this time, the magnet 28 has a tendency to drive the lower slider 13 to push upwards, and further pushes the scraper 10 upwards through the accumulator spring 15. In order to prevent the upward force of the scraper 10 from being too large, combined with Figure 2 and Figure 5 As shown, a limit screw 12 located above the upper slider 9 is threadedly connected to the outer top of the support seat 8. By adjusting the screwing length of the limit screw 12, the upward height of the upper slider 9 is restricted, thereby restricting the contact force between the scraper 10 and the conveyor belt 2. On this basis, as the lower slider 13 continuously pushes upwards until the upper slider 9 abuts against the limit screw 12. At this time, the scraper 10 scrapes and cleans the outer side of the conveyor belt 2 with a constant force, so that the chocolate adhered to the conveyor belt 2 is scraped out.

[0045] On this basis, in order to make the scraper 10 separate from the conveyor belt 2 after scraping for a certain period of time, combined with Figure 5 and Figure 6 It can be seen that a control arm 26 is fixedly movable on the side of the guide seat 6, and the shape of the control arm 26 is "L". The start switch 27 is fixed in the middle of the control arm 26. Under normal conditions, under the action of its own gravity, the control arm 26 moves downward along the guide seat 6 to the limit, and the start switch 27 is also directly opposite to the switch top block 801. When the switch top block 801 presses the start switch 27, the effects described above will be achieved, forcing the limit support plate 16 to continuously push upwards. As the limit support plate 16 continuously moves upwards and compresses the accumulator spring 15, the limit support plate 16 will eventually abut against the control arm 26 and drive the control arm 26 to move upwards synchronously. The control arm 26 drives the start switch 27 to move upwards and move to the upper end of the switch top block 801. After that, since the switch top block 801 no longer contacts the start switch 27, the coil 29 is powered off. Under the action of the pulling force of the counterweight mechanism on the pull rope 17 and the elastic force of the accumulator spring 15, the lower slider 13 will be forced to move downwards along the support seat 8 to the bottom limit, and finally there will be a gap between the scraper 10 and the conveyor belt 2. Moreover, when the lower slider 13 moves downwards, it will no longer provide support for the control arm 26. The control arm 26 also has a tendency to drive the start switch 27 to move downwards under its own gravity. However, since the start switch 27 is a spring-type momentary switch, when the start switch 27 moves downwards, its end will abut above the switch top block 801, and the start switch 27 is blocked by the switch top block 801 and cannot continue to move downwards.

[0046] Finally, when the support base 8 is pulled away from the guide base 6 under the traction of the counterweight mechanism, the support base 8 also drives the switch top block 801 away from the start switch 27. After the switch top block 801 no longer blocks the start switch 27, under the action of the gravity of the control arm 26, it will move downward along the guide base 6 to the bottom limit until the start switch 27 and the switch top block 801 are aligned again and wait for the detection and cleaning of the next chocolate residue.

[0047] Embodiment 2 is a further improvement based on Embodiment 1. Please refer to Figure 2 and Figure 5 It can be seen that the guide rod 7 and the support frame 5 are in a movable sleeved relationship. A return spring 700 sleeved on the outer part of the guide rod 7 is installed between the guide base 6 and the support frame 5. Under the elastic force of the return spring 700, the guide base 6 always has a tendency to move away from the support frame 5. In order to prevent the separation between the guide rod 7 and the support frame 5, a screw is threadedly connected to the end of the guide rod 7 away from the guide base 6, and the movement range of the guide rod 7 is limited by the screw to avoid the separation between the guide rod 7 and the support frame 5. Combining Figures 5 - 7 It can be seen from that there is an anti - detachment bracket 30 fastened to the guide base 6 by bolts. Correspondingly, an anti - detachment ejector rod 161 is fixedly installed on the side of the limit support plate 16. Referring to Figure 7 It can be seen that the anti - detachment ejector rod 161 is a combined body of two cylinders with different diameters. Combining Figure 6 It can be seen that a cylindrical groove and a rectangular groove for the anti - detachment ejector rod 161 to pass through are formed on the anti - detachment bracket 30. When the anti - detachment ejector rod 161 passes through the cylindrical groove and moves upward, the rectangular groove can be used to limit the anti - detachment ejector rod 161 so that the anti - detachment ejector rod 161 can only move up and down along the rectangular groove on the anti - detachment bracket 30.

[0048] The advantage of this design is that when the switch top block 801 on the support base 8 presses the start switch 27, the anti - detachment ejector rod 161 will enter the cylindrical groove on the anti - detachment bracket 30. As the start switch 27 energizes the coil 29 and generates a magnetic force repulsive to the magnet 28, the magnet 28 drives the anti - detachment ejector rod 161 to move upward synchronously along the rectangular groove through the limit support plate 16. At the same time, during the upward movement of the limit support plate 16, as Figure 2As shown, when the counterweight mechanism at the end of the drawstring 17 moves upward to the limit, the lower baffle 14 pulls the drawstring 17 to move upward synchronously. Since neither the support base 8 nor the counterweight mechanism can move, this causes the upward-moving lower baffle 14 to force the support base 8 to tend to move in the direction of the support frame 5 on the basis of pulling the drawstring 17, and squeeze the reset push spring 700 through the guide seat 6, causing the scraper 10 to move along the conveyor belt 2. After that, when the limit support plate 16 pushes the control arm 26 upward and releases the extrusion on the start switch 27, under the elastic force of the reset push spring 700, the scraper 10 will be quickly reset. At this time, the reset speed is relatively greater than the running speed of the conveyor belt 2. This purpose can ensure that when the scraper 10 is away from the guide seat 6, the conveyor belt 2 that has been cleaned will not push the scraper 10 to move, ensuring that the scraper 10 has enough recovery time. This purpose can ensure that there is enough time for the support base 8 to disengage from the start switch 27.

[0049] Embodiment 3 is a further improvement on the basis of Embodiment 2. As another counterweight mechanism, as Figure 2 and Figure 3 shown, there is a reset support 19 fixedly connected to the support frame 5 by bolts, and a drawstring seat 25 is movably installed on the side of the reset support 19. The drawstring seat 25 can only move up and down reciprocally outside the reset support 19. Moreover, the drawstring seat 25 has a relatively light mass. In order to ensure that the drawstring seat 25 has sufficient downward pressure, a cylinder seat 21 is movably installed outside the reset support 19 above the drawstring seat 25, and a cylinder body 22 is fixedly installed on the cylinder seat 21. The cylinder body 22 can be used to increase the downward pressure of the drawstring seat 25, thereby increasing the intensity of dragging the drawstring 17 fixedly connected to the drawstring seat 25 forward. The drawstring 17 changes direction through the pulley, thereby pulling the support base 8 to tend to move away from the guide seat 6.

[0050] Since the adhesion force of chocolate on the conveyor belt 2 is limited, in order to further reduce the movement resistance of the support base 8, combined with Figures 2 - 4It can be seen that a piston 23 is movably installed inside the cylinder block 22, and a plug spring 235 is connected between the piston 23 and the cylinder block 22. Under the elastic force of the plug spring 235, the piston 23 always has a tendency to push outwards. A return push arm 231 is fixedly connected to the end of the piston 23. A rectangular groove for guiding the movement of the return push arm 231 is provided on the outer side of the cylinder block 22. Under the limitation of the rectangular groove, the return push arm 231 can only reciprocate along the axial direction of the cylinder block 22. Similarly, the piston 23 is restricted by the return push arm 231 and cannot rotate inside the cylinder block 22. Correspondingly, a reset slide 20 located on one side of the return push arm 231 is fixedly installed at the bottom of the support frame 5, and the surface of the reset slide 20 is inclined. When the piston 23 is pushed outwards by the elastic force of the plug spring 235, the piston 23 abuts against the reset slide 20 through the return push arm 231, causing the return push arm 231 to move along the reset slide 20, forcing the piston 23 to drive the cylinder block 22 to have an upward movement tendency until the central axis of the piston 23 is aligned with the central axis of the guide rod 7.

[0051] Reference Figure 3 and Figure 4 It can be seen that a one-way air valve 233 and an air vent 234 are provided in the piston 23. Since the air vent 234 is a through hole, the inner cavity of the cylinder block 22 can be directly communicated with the outside through the air vent 234. Therefore, the air vent 234 can quickly introduce external air into the inner cavity of the cylinder block 22, while the one-way air valve 233 can only release the air in the cylinder block 22 to the outside unidirectionally. Moreover, by controlling the aperture of the one-way air valve 233 installed, the rate of air flow out of the inner cavity of the cylinder block 22 can be controlled. A switching arm 232 is movably installed on the surface of the piston 23. After the switching arm 232 deflects up / down to the limit, it can block the corresponding one-way air valve 233 / air vent 234. In addition, in order to facilitate the switching of the switching arm 232, an upper limit rod 24 and a lower limit rod 241 arranged up and down are fixedly installed on the side of the reset support 19. Among them, the upper limit rod 24 is directly above the lower limit rod 241, and the switching arm 232 is located between the upper limit rod 24 and the lower limit rod 241.

[0052] Under normal conditions, the support seat 8 is relatively far away from the guide seat 6, and the switch top block 801 will not squeeze the start switch 27. The elastic force of the reset push spring 700 pushes the guide seat 6 to be relatively far away from the support frame 5. The elastic force of the plug spring 235 pushes the piston 23 to push outwards, causing the return push arm 231 to move upwards along the reset slide 20 until the piston 23 and the guide rod 7 are coaxially arranged. At this time, the cylinder seat 21 is located above the rope traction seat 25, and there is a spacing between them.

[0053] The conveyor belt 2 is used to convey large pieces of chocolate. When chocolate adheres to the conveyor belt 2, the protruding chocolate will cause the scraper 10 to tend to move towards the guide seat 6. It should be noted that since the cylinder seat 21 is located above the rope pulling seat 25 at this time, and the mass of the rope pulling seat 25 is relatively light, the adhered chocolate is more likely to push the scraper 10 towards the guide seat 6.

[0054] When the switch top block 801 on the support seat 8 contacts and presses the start switch 27, the anti - detachment ejector rod 161 enters the cylindrical groove of the anti - detachment pull frame 30. Then, the coil 29 is energized and generates a magnetic force repulsive to the magnet 28. The magnet 28 is used to drive the limit support plate 16 to move upward synchronously. On the one hand, the anti - detachment ejector rod 161 passes over the cylindrical groove on the anti - detachment pull frame 30 and moves upward along the rectangular groove. On the other hand, as the lower slide block 13 drives the lower baffle 14 to move upward, the pull rope 17 will be further pulled, forcing the pull rope 17 to pull the rope pulling seat 25 to move further upward until the rope pulling seat 25 abuts against the cylinder seat 21, and the upward movement of the rope pulling seat 25 is limited by the cylinder seat 21.

[0055] As the lower baffle 14 continuously moves upward and the pull rope 17 is continuously tightened upward, until the anti - detachment ejector rod 161 drags the guide seat 6 towards the support frame 5 through the anti - detachment pull frame 30, and at the same time compresses the reset push spring 700. At the same time, the scraper 10 abuts against the conveyor belt 2 and moves along the conveyor belt 2 towards the support frame 5, so that the scraper 10 scrapes the chocolate on the conveyor belt 2. When the guide rod 7 moves towards the cylinder body 22, it will squeeze the piston 23. After being pressed, the piston 23 will squeeze the top plug spring 235 and the air flow in the inner cavity of the cylinder body 22. Since the cylinder body 22 is at the upper limit position, on the premise that the upper limit rod 24 blocks the switching arm 232, the air leakage hole 234 is blocked, so that the air flow in the piston 23 can only be slowly discharged from the one - way air valve 233, thereby reducing the tendency of the guide seat 6 to move towards the support frame 5. It can be seen from this that by controlling the exhaust rate of the one - way air valve 233, the scraping rate of the scraper 10 along the conveyor belt 2 can be controlled.

[0056] After the limit support plate 16 continuously moves upward, it will eventually reach the control arm 26, thereby pushing the control arm 26 upward and separating the start switch 27 from the switch top block 801. At this time, the coil 29 is powered off, and under the elastic force of the reset push spring 700, the guide seat 6 quickly resets, that is, the guide seat 6 moves away from the support frame 5. At the same time, when the guide seat 6 moves towards the support frame 5, there is a tendency to pull the traction rope 17 through the support seat 8. By pulling the traction rope 17, the downward reset of the lower baffle 14 is further aggravated. When the guide seat 6 resets to its normal state. Since the air flow in the cylinder block 22 cannot be supplemented externally at this time, even under the elastic force of the top plug spring 235, the piston 23 still cannot be pushed outwards. After that, under the gravity of the cylinder block 22 and the cylinder seat 21, the rope pulling seat 25 will be pressed downwards until the rope pulling seat 25 quickly moves downward and pulls the support seat 8 away from the guide seat 6 quickly through the traction rope 17. When the switching arm 232 on the cylinder block 22 moves downward and contacts the lower limit rod 241, the switching arm 232 is deflected upward by the block of the lower limit rod 241, and the air release hole 234 is opened. At this time, the external air flow can be supplemented into the cylinder block 22 through the air release hole 234. Under the elastic force of the top plug spring 235, the return push arm 231 is quickly pushed outwards. When the return push arm 231 reaches the reset slide 20, it will move upward along the reset slide 20 until the piston 23 and the guide rod 7 are coaxially aligned again. After that, since the cylinder seat 21 no longer presses on the rope pulling seat 25, the rope pulling seat 25 will no longer be able to pull the support seat 8 to move again. After that, as the conveyor belt 2 continuously moves, when the area of the conveyor belt 2 that has been cleaned completely passes beyond the scraper 10, the scraper 10 can detect and clean the subsequent input area on the conveyor belt 2. In this way, the cycle is repeated to ensure that the scraper 10 can clean the conveyor belt 2 in a timely manner.
