Description

Technical Field

[0001] The present invention relates to the technical field of automatic blanking, and particularly to an automatic blanking production device for strip-shaped profiles. Background Art

[0002] The production of strip-shaped profiles is usually directly carried out by a plastic extruder. The plastic extruder heats solid plastic to a molten state through methods such as pressurization and shearing, and then extrudes it through a die under the action of pressure to form various shaped plastic products.

[0003] The operation of a plastic extruder usually requires raw materials to enter the barrel through a hopper and be pushed by a screw to the heating area. Inside the barrel, the plastic is subjected to the shearing of the screw and the heating of the barrel, gradually softening and melting into a uniform melt. The melt is pushed by the screw and extruded through the die to form the required product shape. The extruded product passes through a cooling device, and after cooling and solidifying, it reaches the required size and shape. The reasons for using a plastic extruder to produce strip-shaped profiles are mainly based on its advantages in terms of high efficiency, flexibility, cost-effectiveness, and product quality.

[0004] However, in the prior art, during the blanking process of a plastic extruder, the raw materials are usually directly fed into the hot melt tank through the feeding port. However, directly feeding the raw materials into the hot melt tank may cause excessive accumulation of raw materials in the hot melt tank, resulting in insufficient melting and thus the product quality not meeting the requirements. Therefore, it does not meet the existing needs, and for this reason, we propose an automatic blanking production device for strip-shaped profiles. Summary of the Invention

One end of the plugging sliding groove is communicated with the connecting hose, and the other end of the plugging sliding groove is communicated with a water supply pipe. The water supply pipe is fixedly connected to the outer side wall of the feeding bucket, and the plugging sliding groove is communicated with the hydraulic groove.

[0017] The present invention has the following beneficial effects: 1. For the automatic blanking production device for strip profiles, through the design of the driving component, the rotating shaft is driven to rotate, so as to help the raw materials in the feeding bucket enter the tank through the sieve plate. During the movement of the raw material conveyor belt, the sliding ring and the cross connecting rod are driven to slide up and down in the feeding bucket. The spiral slider arranged in the insertion slot and the spiral groove formed on the outer side wall of the rotating shaft enable the sliding ring and the cross connecting rod to drive the rotating shaft to rotate during the up and down sliding process. Through the rotation of the rotating shaft, the sweeping plate and the stirring rod fixedly connected to the side wall of the rotating shaft start to rotate. The rotation of the sweeping plate can move the raw materials located above the sieve plate, so that the raw materials fall into the tank through the sieve holes in the sieve plate. The rotation of the stirring rod makes the piled raw materials have a large activity space, preventing the raw materials from being too much and causing the sweeping plate to be stuck and unable to rotate. Through the blocking of the sieve plate and the rotation of the sweeping plate, the speed of the raw materials entering the tank is slowed down, ensuring the full melting of the raw materials in the tank, and thus ensuring the quality of the produced products.

[0018] 2. The automatic blanking production device for strip profiles, through the design of the weight-based shutdown component, effectively prevents excessive raw materials from accumulating in the feeding bucket. When there is too much raw material in the feeding bucket, the sieve plate will slide downward in the vibration chute under the influence of gravity. At this time, the side wall of the sieve plate touches the conical drive block and drives the conical drive block to slide into the feeding bucket. Since the vibration chute is filled with hydraulic oil, the contact slider located in the feeding bucket slides outward synchronously. And because the horizontal height of the contact slider is higher than that of the contact plate, during the downward movement of the sliding ring and the cross connecting rod, the drive plate inside them will not touch the contact plate, so the blocking plate will not open. At the same time, the lifting and lowering of the sliding ring and the cross connecting rod continue, so the rotation of the material sweeping plate and the stirring rod still operates. At the same time, to ensure the normal operation of the drive component, the T-shaped telescopic rod is designed as a telescopic part. When the sliding ring and the cross connecting rod touch the contact slider, the T-shaped telescopic rod will not get stuck because the left and right sliding blocks do not rotate to the lowest position, ensuring the normal operation of the drive component. This design makes it so that when there is too much raw material accumulated in the feeding bucket, no more raw material will enter the feeding bucket. At the same time, through the rotation of the material sweeping plate and the stirring rod, it is ensured that the raw material in the sieve plate can enter the tank normally and orderly. This design reduces the rate of raw material entering the tank while preventing the situation of excessive raw material accumulation in the feeding bucket.

[0019] 3. The automatic blanking production device for strip profiles, through the design of the temperature reduction component, can achieve cooling the raw materials by spraying when there is raw material accumulation in the feeding bucket. When there is too much raw material accumulated in the feeding bucket, the hydraulic oil in the hydraulic tank simultaneously drives the sealing slide plate to slide upward in the sealing chute. At this time, the cooling channel, the connecting hose, the communication hole and the water supply pipe are connected. Through the water supply of the water supply pipe and the spraying of the cooling nozzle, the accumulated raw materials can be effectively cooled. At the same time, under the stirring action of the stirring rod, the accumulated raw materials can be stirred loose to facilitate the entry of cold air into the interior of the accumulated raw materials. This design effectively reduces the situation of raw material melting when there is too much raw material accumulated in the feeding bucket, ensures the physical properties of the raw materials in the feeding bucket, and effectively prevents the raw materials from melting in the feeding bucket and then adhering to the inner wall of the feeding bucket.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that directly feeding raw materials into the tank body may cause excessive raw materials and insufficient melting. Please refer to Figures 1 to 12 A belt-shaped profile automatic blanking production device includes a production main body 1. The production main body 1 includes a tank body 11. An inlet bucket 16 is installed above the tank body 11. A raw material conveyor belt 17 is arranged above the inlet bucket 16. A decelerating blanking assembly 2 is arranged in the inlet bucket 16.

[0035] The decelerating blanking assembly 2 includes a sieve plate 21 installed in the inlet bucket 16. A rotating shaft 22 is rotatably connected above the sieve plate 21. A sweeping plate 23 and a stirring rod 24 are fixedly connected to the bottom side wall of the rotating shaft 22.

[0036] The design of the sieve plate 21 reduces the amount of raw materials entering the tank body 11 per unit time. Through the rotation of the sweeping plate 23, the raw materials remaining on the sieve plate 21 can enter the tank body 11 and will not get stuck in the sieve plate 21.

[0037] A motor 12 is installed inside the tank body 11. The output end of the motor 12 is fixedly connected to a conveying screw rod 14. A baffle 13 is inserted on the outer side of one end of the conveying screw rod 14 close to the motor 12. The baffle 13 is fixedly connected inside the inner tank body 11. One end of the tank body 11 away from the motor 12 is fixedly connected to an extrusion port 15. The raw material conveyor belt 17 includes a mounting baffle 171 fixedly connected to the upper end of the feeding bucket 16. A rotating shaft 172 is installed inside the mounting baffle 171. A conveying belt 173 is installed on the side wall of the rotating shaft 172.

[0038] The production main body 1 is used for producing strip-shaped profiles. By heating the tank body 11, the raw materials entering the tank body 11 are melted, and the melted raw materials are conveyed to the extrusion port 15 through the conveying screw rod 14 and extruded through the extrusion port 15. Through the cooling device, the production of strip-shaped profiles is realized (the production process of strip-shaped profiles is prior art, so this solution does not make specific descriptions about it). The design of the raw material conveyor belt 17 ensures the supply of raw materials.

[0039] A sliding ring 27 is arranged at the upper end of the rotating shaft 22. The sliding ring 27 is slidably connected inside the feeding bucket 16. A cross connecting rod 28 is fixedly connected inside the sliding ring 27. A plugging groove 29 and a spiral groove 25 are formed inside the cross connecting rod 28. A spiral slider 26 is slidably connected inside the spiral groove 25. The spiral slider 26 is fixedly connected to the outer side wall of the rotating shaft 22.

[0040] A driving assembly 3 is arranged above the sliding ring 27. The driving assembly 3 includes a driving gear 35 fixedly connected to the outer side wall of the rotating shaft 172. The driving gear 35 is meshed with a driven gear 34. The driven gear 34 is rotatably connected to the inner wall of the feeding bucket 16. A left and right sliding block 33 is fixedly connected to one side of the driven gear 34. The left and right sliding block 33 is slidably connected inside a left and right sliding groove 32. The left and right sliding groove 32 is formed inside a T-shaped telescopic rod 31. The bottom of the T-shaped telescopic rod 31 is fixedly connected to the upper surface of the cross connecting rod 28.

[0041] The drive assembly 3 is designed to drive the rotating shaft 22 to rotate so as to help the raw materials in the feed barrel 16 to enter the tank body 11 through the sieve plate 21. During the movement of the raw material conveyor belt 17, the driving gear 35 on the side wall of the rotating shaft 172 engages with the driven gear 34 to drive the driven gear 34 to rotate. At this time, the left and right sliding blocks 33 fixedly connected to the side walls of the driven gear 34 synchronously start to rotate around the center of the driven gear 34. At the same time, since the left and right sliding blocks 33 are slidably connected in the T-shaped telescopic rod 31, and the T-shaped telescopic rod 31 is fixedly connected to the top of the sliding ring 27 and the cross connecting rod 28, the rotation of the rotating shaft 172 can drive the sliding ring 27 and the cross connecting rod 28 to slide up and down in the feed barrel 16. Through this drive, the sliding ring 27 and the cross connecting rod 28 slide up and down relative to the rotating shaft 22, and the insertion The spiral slider 26 arranged in the connecting groove 29 and the spiral groove 25 opened on the outer wall of the rotating shaft 22 enable the sliding ring 27 and the cross connecting rod 28 to drive the rotating shaft 22 to rotate during the up and down sliding process. Through the rotation of the rotating shaft 22, the sweeping plate 23 and the stirring rod 24 fixedly connected to the side wall of the rotating shaft 22 start to rotate. The rotation of the sweeping plate 23 can move the raw materials above the sieve plate 21, so that the raw materials fall into the tank body 11 through the sieve holes in the sieve plate 21, and the rotation of the stirring rod 24 allows the accumulated raw materials to have a larger activity space, preventing the sweeping plate 23 from being stuck and unable to rotate due to excessive raw materials. The blocking of the sieve plate 21 and the rotation of the sweeping plate 23 slow down the speed of the raw materials entering the tank body 11, ensuring that the raw materials are fully melted in the tank body 11, thereby ensuring the quality of the produced products.

[0042] A stage unloading component 4 is arranged in the sliding ring 27 and the cross connecting rod 28. The stage unloading component 4 includes a rotating groove 41 opened in the cross connecting rod 28. A unloading rotating shaft 42 is rotatably connected in the rotating groove 41. The rotating groove 41 and the unloading rotating shaft 42 are connected by a torsion spring 43. A blocking plate 44 and a driving plate 45 are fixedly connected to the side wall of the unloading rotating shaft 42. The driving plate 45 is used to interfere with the contact plate 46. The contact plate 46 is fixedly connected to the outer wall of the rotating shaft 22.

[0043] The stage blanking assembly 4 is used to limit the amount of raw materials entering each time. The blocking plate 44 is used to block the gap between the sliding ring 27 and the cross connecting rod 28. During the downward movement of the sliding ring 27 and the cross connecting rod 28, the driving plate 45 at the bottom of the sliding ring 27 abuts against the abutting plate 46 on the side wall of the rotating shaft 22. Since the bottom of the driving plate 45 is set to an inclined rounded shape and the abutting plate 46 is designed as a cone, when the driving plate 45 abuts against the upper surface of the abutting plate 46, the blanking rotating shaft 42 starts to rotate. At this time, the blocking plate 44 blocking between the sliding ring 27 and the cross connecting rod 28 starts to rotate synchronously. At this time, the raw materials located in the sliding ring 27 and the cross connecting rod 28 will fall into the feeding bucket 16 through the opened gap. Through this design, intermittent feeding is achieved, further reducing the rate of raw materials entering the tank body 11 and ensuring the full melting of the raw materials. The design of the torsion spring 43 ensures the reset function of the blocking plate 44 when the sliding ring 27 and the cross connecting rod 28 slide upward.

[0044] A vibration assembly 5 is arranged at the bottom of the sieve plate 21. The vibration assembly 5 includes a vibration chute 51 opened in the feeding bucket 16. The sieve plate 21 is slidably connected in the vibration chute 51. A vibration spring 52 is fixedly connected to the bottom of the sieve plate 21, and the other end of the vibration spring 52 is fixedly connected in the vibration chute 51. The sieve plate 21 is abutted by a conical driving block 53, and the conical driving block 53 is fixedly connected to the bottom of the sweeping plate 23.

[0045] During the rotation of the sweeping plate 23, the conical driving block 53 at the bottom of the sweeping plate 23 continuously abuts against the inner wall of the sieve hole of the sieve plate 21. Through this design, the sieve plate 21 can be quickly driven to vibrate in the vibration chute 51. Through the vibration of the sieve plate 21, the raw materials remaining on the surface of the sieve plate 21 can be helped to enter the tank body 11 through the sieve holes.

[0046] Embodiment 2. The purpose of this embodiment is to promote the solution of the problem that the raw material aisle continuously enters the feeding bucket 16, resulting in the accumulation of raw materials. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 12 , a weight cut-off operation assembly 6 is arranged on the inner wall of the feeding bucket 16. The weight cut-off operation assembly 6 includes a hydraulic groove 61, an abutting chute 62 and a clamping chute 63 opened in the feeding bucket 16. An abutting slider 64 is slidably connected in the abutting chute 62, and the side wall of the abutting slider 64 is abutted by the sieve plate 21.

[0047] A clamping slider 65 is slidably connected in the clamping chute 63. One side of the clamping slider 65 is fixedly connected with a return spring 66, and the other end of the return spring 66 is fixedly connected in the hydraulic groove 61.

[0048] The design of the rated weight stop assembly 6 effectively prevents excessive accumulation of raw materials in the feed barrel 16. When there are too many raw materials in the feed barrel 16, the sieve plate 21 will be affected by gravity and slide downward in the vibration chute 51. At this time, the side wall of the sieve plate 21 abuts against the conical drive block 53 and drives the conical drive block 53 to slide into the feed barrel 16. Since the vibration chute 51 is filled with hydraulic oil, the abutting slider 64 in the feed barrel 16 slides outward synchronously. And because the horizontal height of the resistance slider 64 is higher than the resistance plate 46, when the sliding ring 27 and the cross connecting rod 28 are descending, the driving plate 45 inside them will not conflict with the resistance plate 46, so the blocking plate 44 will not open, and the lifting and lowering of the sliding ring 27 and the cross connecting rod 28 are still continuing, so the rotation of the sweeping plate 23 and the stirring rod 24 is still running. At the same time, in order to ensure the normal operation of the driving assembly 3, the T-shaped telescopic rod 31 is designed as a highly elastic telescopic member (this design of the T-shaped telescopic rod 31 is a prior art, so this solution will not be described in detail). When the cross connecting rod 28 contacts the sliding block 64, the T-shaped telescopic rod 31 will not get stuck because the left and right sliding blocks 33 have not rotated to the lowest position, thereby ensuring the normal operation of the driving assembly 3. This design ensures that when too much raw material is accumulated in the feed barrel 16, no more raw material will enter the feed barrel 16. At the same time, the rotation of the sweeping plate 23 and the stirring rod 24 ensures that the raw material in the sieve plate 21 can enter the tank body 11 normally and orderly. This design reduces the rate at which the raw material enters the tank body 11 while preventing excessive accumulation of raw material in the feed barrel 16.

[0049] Example 3: This example is intended to help solve the problem that too much raw material accumulated in the feed barrel 16 may cause the heat in the tank 11 to be transferred to the feed barrel 16, causing the raw material to melt. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 12 A cooling component 7 is arranged in the rotating shaft 22, and the cooling component 7 includes a cooling rod 71 fixedly connected to the side wall of the rotating shaft 22, a cooling nozzle 72 is fixedly connected to the bottom of the cooling rod 71, and a cooling channel 73 is opened in the rotating shaft 22 and the cooling rod 71.

[0050] The upper end of the cooling channel 73 is connected to a connecting hose 74, which is fixedly connected to the upper end of the rotating shaft 22. The other end of the connecting hose 74 is fixedly connected to the inner wall of the upper end of the feed barrel 16. A blocking slide 75 is provided in the feed barrel 16. A blocking slide 76 is slidably connected in the blocking slide 75. A connecting hole 77 is provided in the blocking slide 76. One end of the blocking slide 75 is connected to the connecting hose 74, and the other end of the blocking slide 75 is connected to a water supply pipe 78. The water supply pipe 78 is fixedly connected to the outer wall of the feed barrel 16. The blocking slide 75 is connected to the hydraulic groove 61.

[0051] Through the design of the cooling component 7, it is possible to achieve cooling of the raw materials by spraying when the raw materials are piled up in the feeding barrel 16. When the raw materials in the feeding barrel 16 are piled up too much, the hydraulic oil in the hydraulic tank 61 simultaneously drives the plugging slide plate 76 to slide upward in the plugging chute 75. At this time, the cooling channel 73, the connecting hose 74, the communication hole 77 and the water supply pipe 78 are communicated. Through the water supply of the water supply pipe 78 and the spraying of the cooling nozzle 72, the piled-up raw materials can be effectively cooled. At the same time, under the stirring action of the stirring rod 24, the piled-up raw materials can be dispersed, so that cold air can enter the interior of the piled-up raw materials. This design effectively reduces the occurrence of the situation where the raw materials melt when the raw materials in the feeding barrel 16 are piled up too much, ensures the physical properties of the feeding barrel 16 containing the raw materials, and effectively prevents the raw materials from melting in the feeding barrel 16 and then adhering to the inner wall of the feeding barrel 16.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0053] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
