Description

Technical Field

[0001] This utility model relates to the field of nylon chip production technology, and in particular to a nylon chip batching device. Background Technology

[0002] Nylon chips are sheet-like granules obtained by pelletizing nylon due to its low melt strength during production. Nylon is the commercial name for polyamide fiber, also known as nylon. Its basic components are aliphatic polyamides linked by amide-[NHCO]-. It is an important synthetic fiber. Continuous production of nylon chips includes processes such as melting, batching, prepolymerization, polymerization, casting, slicing, and extraction, using caprolactam solid as raw material.

[0003] A nylon chip batching device is disclosed in Chinese utility model patent with publication number CN209521147U, which relates to the field of nylon chip production technology. The device includes a batching box and a weighing structure. The top of the batching box is provided with a feeding hopper, and a cleaning box is fixed on the left side of the batching box. A heating cover is installed at the bottom of the batching box.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: In the above-mentioned device, material is added to the feed hopper via a weighing cylinder, and during this process, manual weighing is required. Subsequently, after weighing is completed, the weighing cylinder is placed into the feed hopper. During this process, the operator needs to repeatedly add material to the weighing cylinder, thereby increasing the difficulty of the operator's work. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a nylon chip feeding device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a nylon chip feeding device, including a storage hopper with an open top, a connecting cylinder installed on the bottom surface of the storage hopper, the connecting cylinder communicating with the storage hopper, a support frame with a U-shaped cross-section fixedly installed on the outer wall of the connecting cylinder, a sliding groove through the side wall of the support frame, a sliding plate slidably installed in the sliding groove, the upper surface of the sliding plate abutting against the bottom surface of the connecting cylinder, a feeding cylinder fixedly installed on the bottom surface of the sliding plate, a through hole through the upper surface of the sliding plate, and the connecting cylinder, the through hole and the feeding cylinder facing each other.

[0007] By adopting the above technical solution, when workers need to prepare ingredients, they need to put the raw materials into the storage hopper. At this time, the storage hopper, connecting cylinder, through hole, and feeding cylinder allow the raw materials in the storage hopper to enter the feeding cylinder. After the raw materials in the storage hopper enter the feeding cylinder, the worker slides the sliding plate, which moves the feeding cylinder under the action of the sliding plate. When the bottom of the feeding cylinder separates from the support frame, the raw materials in the feeding cylinder fall into the machine below under the action of gravity, thus completing the ingredient preparation. After the ingredient preparation is completed, the worker slides the sliding plate in the opposite direction to align the connecting cylinder, through hole, and feeding cylinder for the next ingredient preparation. In this process, the worker only needs to add raw materials to the storage hopper once to complete multiple ingredient preparations, eliminating the need for multiple additions and reducing the workload of the workers.

[0008] Furthermore, a rotating groove is formed through the outer wall of the feeding cylinder, and a reset groove is formed on the inner wall of the rotating groove. A rotating block is rotatably arranged in the rotating groove, and a baffle plate is fixedly arranged on the bottom surface of the rotating block. The bottom surface of the baffle plate abuts against the inner wall of the support frame. A rotating rod is rotatably arranged in the reset groove, and the rotating rod is fixed to the rotating block. A torsion spring is fixedly arranged on the side wall of the rotating rod, and the other end of the torsion spring is fixedly arranged on the inner wall of the reset groove.

[0009] By adopting the above technical solution, when the lower part of the feeding cylinder separates from the support frame, the raw material in the feeding cylinder moves downward under the action of gravity, causing the baffle plate to rotate under the action of the raw material. This, in turn, causes the rotating block and rotating rod to rotate under the action of the baffle plate, allowing the raw material to fall into the machine below. Subsequently, after all the raw material has fallen into the machine below, the rotating rod, rotating block, and rotating plate rotate under the action of the torsion spring. During this process, the baffle plate reduces the probability of raw material remaining on the support frame.

[0010] Furthermore, a connecting groove is provided through the side wall of the support frame, a connecting rod is slidably arranged in the connecting groove, the connecting rod is fixed to the slide plate, an mounting rod is rotatably arranged on the bottom surface of the connecting rod, and a rocker arm is rotatably arranged at the end of the mounting rod away from the connecting rod.

[0011] Furthermore, a support plate is fixedly installed on the side wall of the support frame, a motor is fixedly installed on the upper surface of the support plate, a drive gear is fixedly installed at the end of the output shaft of the motor, a driven gear is fixedly installed on the bottom surface of the rocker arm, the drive gear and the driven gear mesh with each other, the drive ratio of the drive gear and the driven gear is 1:1, and the drive gear has teeth only at 1 / 2 of its length.

[0012] By adopting the above technical solution, when the worker needs to slide the slide plate, the worker needs to start the motor, which in turn rotates the motor's output shaft. This causes the drive gear to rotate under the action of the motor's output shaft, which in turn causes the driven gear to rotate under the action of the drive gear. This causes the rocker arm to rotate under the action of the driven gear, which in turn causes the connecting rod to slide under the action of the rocker arm and the mounting rod. This causes the slide plate to rotate under the action of the connecting rod. In this process, after the driven gear rotates one revolution, the connecting rod completes one reciprocating slide, thus completing one batching operation. In addition, since the drive ratio of the drive gear to the driven gear is 1:1, and the drive gear only has teeth at half its length, the drive gear rotates two revolutions for the driven gear to rotate one revolution. Also, because the drive gear only has teeth at half its length, there is a pause after the driven gear rotates half a revolution (during which the feeding cylinder can complete loading and unloading). During this process, the worker does not need to manually slide the slide plate, thus reducing the difficulty of the worker's work.

[0013] Furthermore, both ends of the mounting rod are fixedly provided with limit rods, and the two connecting rods pass through the rocker arm and the connecting rod respectively and are rotatably connected to them. The outer walls of the two limit rods are threaded with limit rings, and the two limit rings abut against the side walls of the rocker arm and the connecting rod.

[0014] By adopting the above technical solution, the limiting rod and limiting ring reduce the probability of the rocker arm and the connecting rod and mounting rod separating from each other, thereby improving the stability of the device.

[0015] Furthermore, a support rod is fixedly provided on the upper surface of the support plate, and the support rod passes through the driven gear and is rotatably connected to it.

[0016] Furthermore, a blocking ring is fitted on the outer wall of the support rod, and the upper surface of the blocking ring abuts against the bottom surface of the driven gear.

[0017] By adopting the above technical solution, the support rod and the blocking ring reduce the probability of the driven gear shaking and separating from the driving gear, thereby improving the stability of the device.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when the worker needs to prepare ingredients, the worker needs to put the raw materials into the storage hopper. At this time, the storage hopper, connecting cylinder, through hole, and feeding cylinder allow the raw materials in the storage hopper to enter the feeding cylinder. After the raw materials in the storage hopper enter the feeding cylinder, the worker slides the sliding plate, which moves the feeding cylinder under the action of the sliding plate. When the bottom of the feeding cylinder separates from the support frame, the raw materials in the feeding cylinder fall into the machine below under the action of gravity, thus completing the preparation. After the preparation is completed, the worker slides the sliding plate in the opposite direction to align the connecting cylinder, through hole, and feeding cylinder for the next preparation. In this process, the worker only needs to add raw materials to the storage hopper once to complete multiple preparations, eliminating the need for multiple additions, thereby reducing the difficulty of the worker's work.

[0020] 2. In this application, when the lower part of the feeding cylinder separates from the support frame, the raw material inside the feeding cylinder moves downward under the action of gravity, thereby causing the baffle plate to rotate under the action of the raw material. This causes the rotating block and rotating rod to rotate under the action of the baffle plate, thus allowing the raw material to fall into the machine below. Subsequently, after all the raw material has fallen into the machine below, the rotating rod, rotating block, and rotating plate rotate under the action of the torsion spring. During this process, the baffle plate reduces the probability of raw material remaining on the support frame.

[0021] 3. In this application, when the worker needs to slide the slide plate, the worker needs to start the motor, which in turn rotates the motor's output shaft. This causes the drive gear to rotate under the action of the motor's output shaft, which in turn causes the driven gear to rotate under the action of the drive gear. This causes the rocker arm to rotate under the action of the driven gear, which in turn causes the connecting rod to slide under the action of the rocker arm and the mounting rod. This causes the slide plate to rotate under the action of the connecting rod. During this process, after the driven gear rotates one revolution, the connecting rod completes one reciprocating slide, thus completing one batching operation. In addition, since the drive ratio between the drive gear and the driven gear is 1:1, and the drive gear only has teeth at half its length, the drive gear rotates two revolutions while the driven gear rotates one revolution. Also, since the drive gear only has teeth at half its length, there will be a pause after the driven gear rotates half a revolution (during which the feeding cylinder can complete loading and unloading). During this process, the worker does not need to manually slide the slide plate, thus reducing the difficulty of the worker's work. Attached Figure Description

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4 As shown in the embodiment of this application, a nylon chip feeding device is disclosed, including a storage hopper 1, a connecting cylinder 11, a support frame 12, a sliding plate 13, a feeding cylinder 14, a rotating block 3, a blocking plate 31, a rotating rod 32, a torsion spring 33, a connecting rod 4, a mounting rod 41, a rocker arm 42, a support plate 5, a motor 51, a drive gear 52, and a driven gear 53. The axis of the storage hopper 1 is vertical, and the connecting cylinder 11 is installed on the bottom surface of the storage hopper 1, with its axis coinciding with the axis of the storage hopper 1. The connecting cylinder 11 and the storage hopper 1 are interconnected. The cross-section of the support frame 12 is U-shaped, and the support frame 12 is fixedly installed on the outer wall of the connecting cylinder 11. A sliding groove 2 is provided through the side wall of the support frame 12. The sliding plate 13 is a rectangular plate structure, and the sliding plate 13 is slidably installed in the sliding groove 2. The upper surface of the sliding plate 13 abuts against the bottom surface of the connecting cylinder 11, and a through hole 21 is provided through the upper surface of the sliding plate 13. The feeding cylinder 14 is fixedly installed on the bottom surface of the slide plate 13, and its axis coincides with the axis of the storage hopper 1. The connecting cylinder 11, the through hole 21 and the feeding cylinder 14 are directly opposite each other.

[0029] When the operator needs to prepare the ingredients, they must place the raw materials into the storage hopper 1. At this time, the storage hopper 1, connecting cylinder 11, through hole 21, and feeding cylinder 14 are connected, allowing the raw materials in the storage hopper 1 to enter the feeding cylinder 14. After the raw materials in the storage hopper 1 enter the feeding cylinder 14, the operator slides the sliding plate 13, causing the feeding cylinder 14 to move under the action of the sliding plate 13. When the bottom of the feeding cylinder 14 separates from the support frame 12, the raw materials in the feeding cylinder 14 fall into the machine below under the action of gravity, thus completing the preparation. After the preparation is completed, the operator slides the sliding plate 13 in the opposite direction to align the connecting cylinder 11, through hole 21, and feeding cylinder 14 so that the next preparation can be carried out. In this process, the operator only needs to add raw materials to the storage hopper 1 once to complete multiple preparations, eliminating the need for multiple additions and reducing the difficulty of the operator's work.

[0030] A rotating groove 22 is formed through the outer wall of the feeding cylinder 14, and a reset groove 23 is formed on the inner wall of the rotating groove 22. A rotating block 3 is rotatably disposed within the rotating groove 22, and a baffle plate 31 is fixedly disposed on the bottom surface of the rotating block 3, with the bottom surface of the baffle plate 31 abutting against the inner wall of the support frame 12. A rotating rod 32 is rotatably disposed within the reset groove 23, with its axis horizontal, and the rotating rod 32 is fixed to the rotating block 3. One end of a torsion spring 33 is fixedly disposed on the side wall of the rotating rod 32, and the other end of the torsion spring 33 is fixedly disposed on the inner wall of the reset groove 23.

[0031] When the lower part of the feeding cylinder 14 separates from the support frame 12, the raw material inside the feeding cylinder 14 moves downward under the action of gravity, causing the baffle plate 31 to rotate under the action of the raw material. This causes the rotating block 3 and the rotating rod 32 to rotate under the action of the baffle plate 31, thus causing the raw material to fall into the machine below. Subsequently, after all the raw material has fallen into the machine below, the rotating rod 32, the rotating block 3, and the rotating plate rotate under the action of the torsion spring 33. During this process, the baffle plate 31 reduces the probability of raw material remaining on the support frame 12.

[0032] A connecting groove 24 is provided through the side wall of the support frame 12. The connecting rod 4 is slidably disposed in the connecting groove 24 and is fixed to the slide plate 13. The mounting rod 41 is rotatably disposed on the bottom surface of the connecting rod 4, and the rocker arm 42 is rotatably disposed at the end of the mounting rod 41 away from the connecting rod 4.

[0033] The support plate 5 is a rectangular plate structure, and is fixedly mounted on the side wall of the support frame 12. The motor 51 is fixedly mounted on the upper surface of the support plate 5, and its output shaft axis is vertical. The drive gear 52 is fixedly mounted on the end of the output shaft of the motor 51, and its axis coincides with the axis of the output shaft of the motor 51. The driven gear 53 is fixedly mounted on the bottom surface of the rocker arm 42, and its axis is vertical. The drive gear 52 and the driven gear 53 mesh with each other, and the drive ratio between the drive gear 52 and the driven gear 53 is 1:1. The drive gear 52 has teeth only at half its length.

[0034] When the operator needs to slide the slide plate 13, the operator needs to start the motor 51, which will cause the output shaft of the motor 51 to rotate. This will cause the drive gear 52 to rotate under the action of the output shaft of the motor 51, which in turn causes the driven gear 53 to rotate under the action of the drive gear 52. This will cause the rocker arm 42 to rotate under the action of the driven gear 53, which will then cause the connecting rod 4 to slide under the action of the rocker arm 42 and the mounting rod 41. This will cause the slide plate 13 to rotate under the action of the connecting rod 4. During this process, after the driven gear 53 rotates one revolution, the connecting rod 4 completes one reciprocating slide, thus completing one batching operation. Furthermore, since the drive ratio of the drive gear 52 to the driven gear 53 is 1:1, the drive gear 52 has teeth at only 1 / 2 of its length, which causes the drive gear 52 to rotate two revolutions and the driven gear 53 to rotate one revolution. Also, since the drive gear 52 has teeth at only 1 / 2 of its length, there will be a pause after the driven gear 53 rotates half a revolution (during which the feeding cylinder 14 can complete the loading and unloading). During this process, there is no need for the staff to manually slide the slide plate 13, thereby reducing the difficulty of the staff's work.

[0035] To improve the stability of the device, limit rods 6 are fixedly installed at both ends of the mounting rod 41. Two connecting rods 4 pass through the rocker arm 42 and the connecting rod 4 respectively and are rotatably connected to them. Limiting rings 61 are threadedly connected to the outer walls of the two limit rods 6, and the two limiting rings 61 abut against the side walls of the rocker arm 42 and the connecting rod 4. The limit rods 6 and the limiting rings 61 reduce the probability of the rocker arm 42 and the connecting rod 4 separating from the mounting rod 41, thereby improving the stability of the device.

[0036] To improve the stability of the device, a support rod 7 is fixedly installed on the upper surface of the support plate 5. The support rod 7 passes through the driven gear 53 and is rotatably connected to it. A blocking ring 8 is sleeved on the outer wall of the support rod 7, and the upper surface of the blocking ring 8 abuts against the bottom surface of the driven gear 53. The support rod 7 and the blocking ring 8 reduce the probability of the driven gear 53 shaking and separating from the drive gear 52, thereby improving the stability of the device.

[0037] The operating principle of the nylon chip batching device in this embodiment is as follows: When the operator needs to batch the material, the operator needs to put the raw material into the storage hopper 1. At this time, the storage hopper 1, connecting cylinder 11, through hole 21 and feeding cylinder 14 are connected, so that the raw material in the storage hopper 1 enters the feeding cylinder 14. After the raw material in the storage hopper 1 enters the feeding cylinder 14, the operator slides the sliding plate 13, so that the feeding cylinder 14 moves under the action of the sliding plate 13. When the bottom of the feeding cylinder 14 separates from the support frame 12, the raw material in the feeding cylinder 14 falls into the machine below under the action of gravity, thus completing the batching. After the batching is completed, the operator slides the sliding plate 13 in the opposite direction to make the connecting cylinder 11, through hole 21 and feeding cylinder 14 aligned, so that the next batching can be carried out. In this process, the operator only needs to add raw material to the storage hopper 1 once to complete multiple batchings, without the need for multiple additions, thus reducing the difficulty of the operator's work.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
