Description

Technical Field

[0001] This invention belongs to the field of synchronous belt production and processing technology, and in particular relates to a synchronous belt and processing equipment. Background Technology

[0002] Synchronous belts, as a key component widely used in industrial transmission, play a vital role in modern manufacturing. With the continuous improvement of industrial automation and the increasing demand for precision transmission in various industries, the application scenarios of synchronous belts are becoming increasingly diversified, and the requirements for their specifications and quality are becoming increasingly stringent. However, existing synchronous belt processing equipment often faces the following technical problems when injection molding synchronous belts: On the one hand, existing equipment often involves complicated operations when adjusting the width and thickness of the timing belt, requiring staff to make tedious manual adjustments. This is not only inefficient, but also makes it difficult to guarantee the accuracy of each adjustment due to human error, resulting in low dimensional accuracy of the produced timing belts, which cannot meet the strict requirements of different industrial scenarios for timing belt specifications. On the other hand, in terms of controlling the injection volume, the existing technology lacks an effective real-time adjustment mechanism. When the width and thickness of the synchronous belt change, the injection volume per unit time cannot be accurately adjusted according to the actual cross-sectional area of ​​the synchronous belt. If the injection volume is too high, the synchronous belt will deform due to excessive pressure during the injection process, and defects such as bubbles or blemishes will appear on the surface. If the injection volume is too low, the synchronous belt will not be fully filled, affecting its overall quality and performance, reducing the product qualification rate, and increasing production costs. Summary of the Invention

[0009] Preferably, the flow control mechanism includes a three-way pipe fixedly connected to the top of the processing mold box. Two of the three-way pipe's ports are connected to the interior of the processing mold box, and the upper end of the other port is fixedly connected to a control box.

[0012] A synchronous belt, which is manufactured by the aforementioned synchronous belt processing equipment.

[0013] Compared with existing technologies, the advantages of this synchronous belt and processing equipment are: 1. This invention, by setting up a flow channel control mechanism, delivers the injection molding raw material into the adjustable injection flow channel formed between two lateral control plates and two transverse control plates during the processing, thereby realizing the injection molding of the synchronous belt. Before this, the width of the synchronous belt can be adjusted by adjusting the distance between the two lateral control plates, and the thickness of the synchronous belt can be adjusted by adjusting the distance between the two transverse control plates, thus processing the synchronous belt of the required specifications.

[0014] 2. This invention, through the setting of an electronic control mechanism, when it is necessary to adjust the distance between the two lateral control plates, uses a first motor in the lateral control assembly to drive the first threaded rod to rotate, allowing the lifting block to move up and down. This, in turn, drives the two lateral control plates to move closer or further apart through the first hinge seat, the second hinge seat, and the connecting rod. When it is necessary to adjust the distance between the two transverse control plates, the air pressure in the telescopic rings on both sides of the transverse control plates is controlled to adjust the distance between the two transverse control plates. This eliminates the need for manual control by the operator and does not obstruct the injection flow channel formed between the two lateral control plates and the two transverse control plates, ensuring the quality of the processed synchronous belt.

[0015] 3. By setting up a flow control mechanism, after the processing width and thickness of the synchronous belt are adjusted, the distance between the two piston plates in the control box can be adjusted through multiple liquid storage tanks and corresponding piston columns, thereby adjusting the injection volume per unit time. When the width and thickness of the synchronous belt are large, more injection material is drawn in and discharged per unit time, thus ensuring that the injection material can quickly and evenly fill the injection channel. When the width and thickness of the synchronous belt are small, less injection material is drawn in and discharged per unit time, avoiding deformation and defects caused by excessive pressure.

[0018] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] Example: Refer to Figures 1 to 8 A synchronous belt processing device, comprising: The processing mold box 1 has a material discharge port at its lower end; The flow channel control mechanism 2 is used to adjust the width and thickness of the injection-molded synchronous belt according to the requirements. The flow channel control mechanism 2 includes two lateral control plates 21 that are symmetrically arranged and slidably connected to the inner wall of the processing mold box 1. Two control slots 22 are symmetrically opened on both sides of the lateral control plates 21. Two symmetrically arranged transverse control plates 23 are slidably connected in the two control slots 22. A telescopic ring 24 is sealed between the transverse control plates 23 and the inner wall of the control slots 22. A fixing rod 25 is fixedly connected to the side wall of the lateral control plates 21 for connecting the part of the lateral control plates 21 that is separated by the transverse control plates 23 and the control slots 22. It should be noted in advance that when it is necessary to process a timing belt with special tooth shape, the side walls of the lateral control plate 21 and the transverse control plate 23 can be set to tooth shape to ensure the processing effect. An adjustable injection flow channel is formed between the two lateral control plates 21 and the two transverse control plates 23; To address the problems of complex and low-precision operation in adjusting the width and thickness of synchronous belts in existing synchronous belt processing equipment, this invention sets up a flow channel control mechanism 2. During the processing, the injection molding raw material is transported into an adjustable injection flow channel formed between two lateral control plates 21 and two transverse control plates 23 to achieve injection molding of the synchronous belt. Before this, the width of the synchronous belt can be adjusted by adjusting the distance between the two lateral control plates 21, and the thickness of the synchronous belt can be adjusted by adjusting the distance between the two transverse control plates 23, thereby processing synchronous belts of the required specifications to meet the strict requirements of synchronous belt specifications in different industrial scenarios.

[0020] The electronic control mechanism 3 is used to automatically adjust the distance between the two lateral control plates 21 and the two transverse control plates 23. The electronic control mechanism 3 includes a lateral control component 31 and a transverse control component 32. The lateral control component 31 is used to adjust the distance between the two lateral control plates 21, and the transverse control component 32 is used to adjust the distance between the two transverse control plates 23.

[0021] The lateral control assembly 31 includes a push rod 311 fixedly connected to two lateral control plates 21. The part of the push rod 311 extending outside the processing mold box 1 is fixedly connected to a first hinge seat 312. A first motor 313 is fixedly connected to the top of the processing mold box 1. A first threaded rod 314 is fixedly connected to the output end of the first motor 313. A lifting block 315 is threadedly connected to the first threaded rod 314. A second hinge seat 316 is fixedly connected to the lower ends of both sides of the lifting block 315. A connecting rod 317 is hinged between the second hinge seat 316 and the corresponding first hinge seat 312.

[0022] Specifically, two limiting rods 318 are fixedly connected to the top of the processing mold box 1. The two limiting rods 318 are slidably connected to the lifting block 315. The limiting rods 318 limit the lifting block 315, so that the lifting block 315 can only move in the vertical direction during the rotation of the first threaded rod 314.

[0023] The lateral control assembly 32 includes two support blocks 321 fixedly connected to the side wall of the processing mold box 1. A second threaded rod 322 is rotatably connected between the two support blocks 321. A control cylinder 323 is provided around the threaded position on the second threaded rod 322. A piston block 324 is slidably connected to the inner wall of the control cylinder 323. The piston block 324 is threadedly connected to the second threaded rod 322. A second motor 325 for driving the second threaded rod 322 is fixedly connected to the side wall of one of the support blocks 321. A first air supply pipe 326 is connected between two adjacent telescopic rings 24 on the same side, and a first air guide pipe 327 is connected between the two first air supply pipes 326. A second air supply pipe 328 is connected between the two telescopic rings 24 on the same side that are furthest apart, and a second air guide pipe 329 is connected between the two second air supply pipes 328. The first air guide pipe 327 and the second air guide pipe 329 are respectively connected to both sides of the control cylinder 323.

[0024] Specifically, the piston block 324 is slidably connected to the inner wall of the control cylinder 323 in the horizontal direction, so that the second threaded rod 322 will not drive the piston block 324 to rotate when it rotates.

[0025] To address the problems of error-prone and inefficient manual adjustment of the synchronous belt width and thickness in existing technologies, this invention incorporates an electronic control mechanism 3. When adjustment of the distance between the two lateral control plates 21 is required, the first motor 313 in the lateral control assembly 31 drives the first threaded rod 314 to rotate, causing the lifting block 315 to move up and down. This, in turn, drives the two lateral control plates 21 to move closer or further apart via the first hinge seat 312, the second hinge seat 316, and the connecting rod 317. When adjustment of the distance between the two transverse control plates 23 is required, the second motor 325 in the transverse control assembly 32 drives the second... The threaded rod 322 rotates, causing the piston block 324 to move horizontally within the control cylinder 323. Since the spaces on both sides of the piston block 324 are connected to the two adjacent telescopic rings 24 on the same side and the two telescopic rings 24 that are furthest apart on the same side, the air pressure in the telescopic rings 24 on both sides of the transverse control plate 23 can be controlled, thereby adjusting the distance between the two transverse control plates 23. This achieves automatic control of the distance between the two lateral control plates 21 and the two transverse control plates 23, eliminating the need for manual control by personnel. Furthermore, it does not obstruct the injection flow channel formed between the two lateral control plates 21 and the two transverse control plates 23, ensuring the quality of the processed synchronous belt.

[0026] The flow control mechanism 4 is used to adjust the injection volume per unit time in real time according to the cross-sectional area of ​​the synchronous belt. The flow control mechanism 4 includes a three-way pipe 41 fixedly connected to the top of the processing mold box 1. Two of the connecting ports of the three-way pipe 41 are connected to the interior of the processing mold box 1, and the upper end of the other connecting port is fixedly connected to a control box 42. Two piston plates 43 are sealed and slidably connected inside the control box 42, and an elastic rubber plate 44 is sealed and slidably connected between the two piston plates 43. Liquid storage tanks 45 are fixedly connected to the circumferential side walls of the processing mold box 1, and pistons are sealed and slidably connected inside the liquid storage tanks 45. The piston column 46 extends beyond the reservoir 45 and is fixedly connected to the lateral control plate 21 and the transverse control plate 23 at the corresponding positions. Multiple reservoirs 45 are fixedly connected to interconnected infusion pipes 47 at their ends away from the piston column 46. Control flow channels 48 and diversion pipes 49 are connected between the infusion pipes 47 and the two side walls of the control box 42. The control flow channels 48 are used to control the amount of hydraulic oil entering the two side spaces of the control box 42 when the piston column 46 is compressed to a greater degree. The upper end of the control box 42 is fixedly connected to a drive mechanism 5 for driving the elastic rubber plate 44 to perform reciprocating vertical displacement.

[0027] Specifically, a feed pipe (not shown in the figure) is fixedly connected to the lower side wall of the control box 42, and the feed pipe is connected to the injection molding material storage box, which is used to continuously transport the injection molding material into the control box 42 and further into the processing mold box 1.

[0028] Specifically, a first liquid storage space is formed between the spaces on both sides of the control box 42, the diversion pipe 49, and the control flow channel 48; a second liquid storage space is formed between the control flow channel 48, the infusion pipe 47, and the liquid storage tank 45; both the first and second liquid storage spaces are filled with hydraulic oil. Specifically, the drive mechanism 5 includes a mounting plate 51 fixedly connected to the upper end of the control box 42. A turntable 52 is rotatably connected to one side wall of the mounting plate 51. A third motor 53 for driving the turntable 52 is fixedly connected to the side wall of the mounting plate 51 away from the turntable 52. A drive rod 54 is rotatably connected to the turntable 52 via a pin. The drive rod 54 extends into the control box 42 and is hinged to the elastic rubber plate 44.

[0029] To address the problem in existing technologies where the injection volume cannot be adjusted in real time according to the cross-sectional area of ​​the synchronous belt, which easily leads to poor quality of the synchronous belt, this invention, by setting up a flow control mechanism 4, allows for adjustment of the injection volume per unit time by using multiple liquid storage tanks 45 and corresponding piston columns 46 to regulate the distance between two piston plates 43 within the control box 42 after the processing width and thickness of the synchronous belt have been adjusted. When the width and thickness of the synchronous belt are large, the cross-sectional area of ​​the processed synchronous belt is large. During the injection molding process, more hydraulic oil in the reservoir 45 enters the first reservoir space, and less hydraulic oil in the second reservoir space enters the control box 42. The distance between the two piston plates 43 is relatively long, so that the elastic rubber plate 44 is in a large area under its own elasticity. When the elastic rubber plate moves up and down, more injection molding material is sucked and discharged per unit time, thus ensuring that the injection molding material can quickly and evenly fill the injection channel. When the width and thickness of the synchronous belt are small, the hydraulic oil in the first reservoir flows in reverse to the reservoir 45, and more hydraulic oil in the second reservoir enters the control box 42. The distance between the two piston plates 43 is relatively short, so that the elastic rubber plate 44 is in a small area under the compression of the piston plate 43, so that less injection molding material is sucked and discharged per unit time, avoiding deformation and defects caused by excessive pressure.

[0030] A synchronous belt, which is manufactured by the aforementioned synchronous belt processing equipment.

[0031] The functional principle of this invention can be explained through the following operational methods: When receiving a task to produce synchronous belts of a specific specification, the operator first determines the required width and thickness of the synchronous belt according to the design requirements. For width adjustment, the first motor 313 is started, and its output shaft drives the first threaded rod 314 to rotate. Since the lifting block 315 is threadedly connected to the first threaded rod 314, the lifting block 315 moves up and down. The connecting rod 317 connecting the second hinge seat 316 at the lower ends on both sides and the first hinge seat 312 on the side control plate 21 rotates, thereby pushing or pulling the two side control plates 21, making them move closer or further apart, thus completing the precise adjustment of the synchronous belt width. For thickness adjustment, the second motor 325 is started, driving the second threaded rod 322 to rotate. Because the piston block 324 is connected to the second threaded rod 322 by a sealing thread, it can drive the piston block 324 to move horizontally within the control cylinder 323. The movement of the piston block 324 changes the air pressure in the space on both sides of the control cylinder 323. This air pressure change is transmitted to the telescopic rings 24 on both sides of the transverse control plate 23 through the first air supply pipe 326, the first air guide pipe 327, the second air supply pipe 328, and the second air guide pipe 329. The telescopic rings 24 expand or contract according to the air pressure change, thereby pushing or pulling the transverse control plate 23 to slide within the control groove 22, realizing the adjustment of the distance between the two transverse control plates 23, and completing the setting of the synchronous belt thickness. After the width and thickness are adjusted, the flow channel control mechanism 2 determines the shape and size of the injection channel. At this time, the flow control mechanism 4 automatically adjusts the injection volume according to the changes in the flow channel. When the width and thickness of the synchronous belt are large, that is, when the cross-sectional area of ​​the injection channel is large, the lateral control plate 21 and the transverse control plate 23 move outward, which increases the distance between the two piston plates 43 in the control box 42. The elastic rubber plate 44 expands under its own elasticity, and the area increases. The drive mechanism 5 is started, and the third motor 53 drives the turntable 52 to rotate. The drive rod 54 on the turntable 52 drives the elastic rubber plate 44 to make reciprocating vertical movements in the control box 42 through the pin. Since the elastic rubber plate 44 has a large area, it can suck and discharge more injection material per unit time during its rising and falling process, ensuring that a large amount of injection material is quickly and evenly filled into the larger injection channel. Conversely, when the width and thickness of the synchronous belt are small, the cross-sectional area of ​​the injection flow channel is small, the lateral control plate 21 and the transverse control plate 23 move inward, the distance between the piston plates 43 is shortened, the elastic rubber plate 44 is squeezed and the area becomes smaller. In this way, when the elastic rubber plate 44 reciprocates, the amount of injection molding material sucked and discharged per unit time is reduced, avoiding defects such as deformation and bubbles in the synchronous belt during the injection process due to excessive injection volume. Throughout the injection molding process, the injection molding raw material is continuously transported from the storage box connected to the feed pipe below the control box 42 to the control box 42, and then enters the injection flow channel in the processing mold box 1 through the three-way pipe 41. After the injection molding is completed, the formed synchronous belt is discharged from the discharge port at the lower end of the processing mold box 1, forming a complete synchronous belt production process.
