Description

Technical Field

[0001] This application relates to the field of material conveying, and in particular to a clamping transmission device. Background Technology

[0002] In industrial production, transmission devices are typically used to move products during processing or inspection. Common transmission devices are single-belt drives, where the product is placed on a belt conveyor for transport. This method makes it difficult to inspect or process the bottom of the product. Therefore, clamping transmission devices consisting of two belt drives have emerged on the market. These devices clamp and transport the product, suspending its bottom for easier inspection and processing. However, in traditional belt drives, the belt tension has a crucial impact on the performance and safety of the transmission system. Adjusting belt tension usually requires adjusting the position of the driving or driven pulley, necessitating disassembly of the equipment, which is cumbersome. Furthermore, with clamping transmission devices consisting of two belt drives, adjusting the position of the driving or driven pulley can lead to asymmetry between the two belt drives, resulting in inconsistent clamping channel widths and affecting the clamping effect. Summary of the Invention

[0003] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a clamping transmission device that can adjust the tension of the belt without changing the position of the driving pulley or driven pulley, and is simple, convenient and quick to operate.

[0004] This application also proposes a testing device having the above-mentioned clamping and transmission device.

[0005] The clamping transmission device according to a first aspect embodiment of this application includes:

[0006] The clamping assembly is provided in two parts, and a clamping channel is provided between the two clamping assemblies;

[0007] A pulley assembly is disposed within the clamping assembly. The pulley assembly includes a driving pulley and a driven pulley. The driving pulley is connected to a driving device, and a belt connects the driving pulley and the driven pulley.

[0008] A tension adjustment mechanism is mounted on the clamping assembly to adjust the tension of the belt. The tension adjustment mechanism includes a tension idler wheel, which is located on one side of the belt and can compress and deform the belt. A crank is fixedly connected to the tension idler wheel, and the central axis of the crank is parallel to the central axis of the tension idler wheel. A locking device is connected to the crank. When the locking device is released, the crank can rotate and drive the tension idler wheel to rotate around the crank.

[0009] The clamping transmission device according to the embodiments of this application has at least the following beneficial effects:

[0010] By incorporating two clamping components, the product can be held in the clamping channel between them, and its movement is driven by a pulley system. This structure allows the product to be suspended off the conveyor line, facilitating bottom inspection, processing, and cleaning. A tension adjustment mechanism on the clamping components allows for belt tension adjustment. When the belt is too loose, it can be tightened to prevent slippage or unstable product clamping during transmission. Conversely, when the belt is too tight, it can be loosened to prevent breakage due to excessive tension, thus extending belt life. The tension adjustment mechanism of this application embodiment uses a tension idler pulley located on one side of the belt to compress the belt. The belt deforms under compression and becomes tensioned. The degree of belt deformation varies depending on the position of the tension idler pulley on one side of the belt. Therefore, the belt tension can be adjusted by adjusting the position of the tension idler pulley. A crank is fixedly connected to the tension idler pulley. When the crank rotates, the tension idler pulley rotates with it. Since the central axis of the crank is parallel to the central axis of the tension idler pulley, the central axis of the tension idler pulley rotates around the central axis of the crank. This means the entire tension idler pulley rotates around the central axis of the crank, changing its position and thus the degree of compression on the belt. Therefore, the belt tension can be adjusted by rotating the crank, without needing to adjust the position of the driving or driven pulley, thus maintaining the clamping effect. The operation is simple, convenient, and quick. To prevent the belt tension from changing due to the crank rotating during belt movement, a locking device is connected to the crank. The crank can only be rotated after the locking device is released, improving the stability of the equipment.

[0011] According to some embodiments of this application, a connecting plate is detachably provided between the crank and the tension idler wheel. The connecting plate is provided with a crank connecting position and an idler wheel connecting position. The crank connecting position is connected to the crank, and the idler wheel connecting position is connected to the tension idler wheel.

[0014] According to some embodiments of this application, conveyors are respectively provided at both ends of the clamping channel.

[0015] According to some embodiments of this application, the clamping assembly is provided with a mounting plate, and the driving wheel, the driven wheel, the driving device and the tension idler wheel are respectively fixedly mounted on the mounting plate.

[0016] According to some embodiments of this application, the crank rod passes through the mounting plate, and the locking device includes a fixed shaft seat sleeved on the crank rod, the fixed shaft seat being fixedly mounted on the mounting plate, and a locking nut being provided above the fixed shaft seat, the locking nut being threadedly connected to the crank rod.

[0017] According to some embodiments of this application, the tensioning idler wheel includes a central shaft, a bearing, and an idler wheel outer ring, wherein the bearing is rotatably connected to the central shaft, and the idler wheel outer ring is rotatably connected to the bearing.

[0018] According to some embodiments of this application, the drive wheel includes a transmission rod, a flange bearing, and a drive shaft synchronizer. The transmission rod is connected to the drive device, the flange bearing is connected to the transmission rod, and the drive shaft synchronizer is connected to the flange bearing. A detection device according to a second aspect of this application includes the clamping transmission device described above.

[0019] The detection device according to the embodiments of this application has at least the following beneficial effects:

[0020] The clamping transmission device according to the first aspect embodiment uses two clamping components to clamp the product in the clamping channel between the two components. The product is then moved via a pulley system. This structure allows the product to be suspended from the conveyor line, facilitating bottom inspection, processing, and cleaning. A tension adjustment mechanism on the clamping components allows for belt tension adjustment. When the belt is too loose, it can be tightened to prevent slippage or unstable product clamping during transmission. Conversely, when the belt is too tight, it can be loosened to prevent breakage due to excessive tension, thus extending belt life. The tension adjustment mechanism of this application embodiment uses a tension idler pulley located on one side of the belt to compress the belt. The belt deforms under compression and becomes tensioned. The degree of belt deformation varies depending on the position of the tension idler pulley on one side of the belt. Therefore, the belt tension can be adjusted by adjusting the position of the tension idler pulley. A crank is fixedly connected to the tension idler pulley. When the crank rotates, the tension idler pulley rotates with it. Since the central axis of the crank is parallel to the central axis of the tension idler pulley, the central axis of the tension idler pulley rotates around the central axis of the crank. This means the entire tension idler pulley rotates around the central axis of the crank, changing its position and thus the degree of compression on the belt. Therefore, the belt tension can be adjusted by rotating the crank, without needing to adjust the position of the driving or driven pulley, thus maintaining the clamping effect. The operation is simple, convenient, and quick. To prevent the belt tension from changing due to the crank rotating during belt movement, a locking device is connected to the crank. The crank can only be rotated after the locking device is released, improving the stability of the equipment.

[0035] Reference Figures 1 to 5As shown, a clamping transmission device according to an embodiment of this application can be applied in product inspection, processing, packaging, and other processes. The clamping transmission device of this embodiment has two clamping components 100 arranged opposite each other, with a clamping channel 200 between the two clamping components 100. The two clamping components 100 are symmetrically arranged with respect to the clamping channel 200, which is used for product passage. When the product passes through the clamping channel 200... Two clamping components 100, located on either side of the clamping channel 200, clamp the product and move it forward. By using these two clamping components 100 to move the product, it can be left unattached to the conveyor line, allowing for convenient bottom inspection, processing, and cleaning. Each clamping component 100 is equipped with a pulley assembly 110, which clamps and moves the product. The pulley assembly 110 includes a driving pulley 111 and a driven pulley 112, with a belt 113 between them. The clamping components 100 clamp the product via the belt 113, and the pulley assembly 110 drives the belt 113, thus moving the product while clamping it. The clamping components 100 also include a tension adjustment mechanism 120 to adjust the tension of the belt 113. Mechanism 120 includes a tension idler wheel 121, which is cylindrical and rotatable. The tension idler wheel 121 is disposed adjacent to one side of the belt 113 and applies a lateral force to the belt 113, which can compress and deform the belt 113. When the tension idler wheel 121 is in different positions, the degree of compression on the belt 113 is inconsistent, resulting in inconsistent deformation of the belt 113 and inconsistent tension. Therefore, adjusting the position of the tension idler wheel can adjust the tension of the belt. A crank rod 122 is fixedly connected to the upper end face of the tension idler wheel 121. The crank rod 122 is cylindrical, and its central axis is parallel to the central axis of the tension idler wheel 121. A locking device 130 is connected to the crank rod 122. After the locking device 130 is released, the crank rod 122 can rotate, driving the tension idler wheel 121 to rotate around the crank rod 122. By making the central axis of the crank 122 parallel to the central axis of the tension idler wheel 121, i.e., having a certain eccentricity between the crank 122 and the tension idler wheel 121, the tension idler wheel 121 will rotate around the central axis of the crank 122 when the crank 122 rotates. This changes the position of the tension idler wheel 121 and its pressure on the belt, thus altering the belt tension. With this structure, the tension of the belt 113 can be adjusted simply by loosening the locking device 130 and then rotating the crank 122, without needing to adjust the position of the driving pulley 111 or the driven pulley 112. This simple, quick, and convenient operation greatly improves work efficiency.

[0036] In related technologies, for different transmission devices, the required adjustment range of belt 113 tension varies during daily operation or maintenance. However, the eccentricity of a typical eccentric wheel structure is fixed. When this eccentric wheel structure is applied to a transmission device, the adjustment range of belt 113 tension is fixed, which is difficult to meet practical needs.

[0037] In this embodiment of the application, a connecting plate 123 is detachably connected between the crank 122 and the tension idler wheel 121. The connecting plate 123 is provided with a crank connecting position 124 and an idler wheel connecting position 125. The crank connecting position 124 is connected to the central axis of the crank 122, and the idler wheel connecting position 125 is connected to the central axis of the tension idler wheel 121. By setting a connecting plate 123, the crank 122 and the tension idler wheel 121 are respectively installed at different positions on the connecting plate 123, so that an eccentricity is generated between the crank 122 and the tension idler wheel 121. When the crank 122 rotates, the position of the tension idler wheel 121 will change. The distance between the crank connection position 124 and the idler wheel connection position 125 on the connecting plate 123 determines the size of the eccentricity between the crank 122 and the tension idler wheel 121. Since the connecting plate 123 is detachably connected to the crank 122 and the tension idler wheel 121 in this application, the eccentricity between the crank 122 and the tension idler wheel 121 can be changed by replacing different connecting plates, thereby adapting to different usage requirements. At the same time, since the tension adjustment mechanism 120 has an irregular shape, setting it to be detachable for the crank 122, the tension idler wheel 121, and the connecting plate 123 makes its production, transportation, and installation more convenient.

[0038] In related technologies, the required width of the clamping channel 200 between two clamping components 100 is different when clamping different products.

[0039] To meet the different requirements of various products regarding the distance between the two clamping assemblies 100, in this embodiment, the clamping assembly 100 is connected to a horizontal adjustment device 140. The horizontal adjustment device 140 includes a first slide rail, which includes a horizontally arranged and parallel first fixed rod 141 and a second fixed rod 142. The clamping assembly 100 includes a first clamping assembly 101 and a second clamping assembly 102. The two ends of the first clamping assembly 101 are slidably connected to the first fixed rod 141 and the second fixed rod 142, respectively. The two ends are slidably connected to the first fixed rod 141 and the second fixed rod 142 respectively; the horizontal adjustment device 140 also includes a first threaded adjustment rod 143, the first threaded adjustment rod 143 is threadedly connected to the first fixed seat 147, the two ends of the first threaded adjustment rod 143 are respectively provided with a first threaded part 144 and a second threaded part 145, the threads on the first threaded part 144 and the second threaded part 145 are opposite in direction, the first threaded part 144 is threadedly connected to the first clamping assembly 101, and the second threaded part 145 is threadedly connected to the second clamping assembly 102.

[0040] The first clamping assembly 101 and the second clamping assembly 102 are both slidably connected to the first fixed rod 141 and the second fixed rod 142. When not fixed, the first clamping assembly 101 and the second clamping assembly 102 can slide on the first fixed rod 141 and the second fixed rod 142. By setting a first threaded adjusting rod 143, the first threaded adjusting rod 143 is threadedly connected to the first clamping assembly 101, the second clamping assembly 102 and the first fixed seat 147 respectively. When the first threaded adjusting rod 143 does not rotate, the positions of the first clamping assembly 101 and the second clamping assembly 102 are fixed relative to the first fixed rod 141 and the second fixed rod 142. When the first threaded adjusting rod 143 rotates, the first threaded adjusting rod 143 can drive the first clamping assembly 101 and the second clamping assembly 102 to move on the first slide rail. By providing a first threaded portion 144 and a second threaded portion 145 with opposite thread directions at both ends of the first threaded adjusting rod 143, when the first threaded adjusting rod 143 rotates, the driving directions of the first threaded portion 144 and the second threaded portion 145 are opposite, thereby the movement directions of the first clamping assembly 101 and the second clamping assembly 102 are opposite. By rotating the first threaded adjusting rod 143, the first clamping assembly 101 and the second clamping assembly 102 can be moved closer to each other or further away from each other, thereby adjusting the width of the clamping channel 200.

[0041] Specifically, a first threaded adjusting block 148 is fixedly installed on both the first clamping assembly 101 and the second clamping assembly 102. The first adjusting threaded block 148 is threadedly connected to the first threaded adjusting rod 143. The thread on the first threaded adjusting block 148 on the first clamping assembly 101 is adapted to the thread on the first threaded part 144, and the thread on the first threaded adjusting block 148 on the second clamping assembly 102 is adapted to the thread on the second threaded part 145.

[0042] Specifically, in this embodiment of the application, a first adjusting rotating disk 146 is connected to the threaded adjusting rod 143. By setting the first adjusting rotating disk, it is convenient for the operator to rotate the first threaded adjusting rod, thereby adjusting the distance between the first clamping assembly 101 and the second clamping assembly 102. The operation is simple, convenient and quick.

[0043] Specifically, in this embodiment of the application, the first adjusting rotating disk 146 is provided with a scale to facilitate the operator to accurately adjust the distance between the first clamping component 101 and the second clamping component 102.

[0044] In related technologies, the clamping height requirements vary when the clamping component 100 clamps different products.

[0045] To meet the different height requirements of various products for the clamping assembly 100, in this embodiment, the clamping assembly 100 is connected to a vertical adjustment device 150. The vertical adjustment device 150 includes a second slide rail 151, which includes a third fixed rod 152 and a fourth fixed rod 153 that are vertically arranged and parallel to each other. The two ends of the clamping assembly 100 are slidably connected to the third fixed rod 152 and the fourth fixed rod 153, respectively. The vertical adjustment device 150 also includes a second threaded adjustment rod 154, which is threadedly connected to a second fixed seat 155. The second threaded adjustment rod 154 is threadedly connected to the clamping assembly 100. Through the cooperation between the second slide rail 151, the fixed seat 155, the second threaded adjustment rod 154, and the clamping assembly 100, the second threaded adjustment rod 154 can drive the clamping assembly 100 to move in the vertical direction when rotating, thereby meeting the different height requirements of the clamping assembly 100.

[0046] Specifically, in this embodiment, two vertical adjustment devices can be provided, driving the first clamping component 101 and the second clamping component 102 respectively. By providing two vertical adjustment devices 150 to drive the first clamping component 101 and the second clamping component 102 respectively, the work required by the vertical adjustment device 150 to overcome gravity is smaller, which is suitable for situations where the clamping component 100 has a large self-weight. In this embodiment, only one vertical adjustment device 150 can be provided to drive the clamping component 100 as a whole. In this structure, the first clamping component 101 and the second clamping component 102 can be raised and lowered synchronously, which is suitable for situations where the synchronization between the first clamping component 101 and the second clamping component 102 is high or the self-weight of the clamping component 100 is small.

[0047] Specifically, in this embodiment, a second threaded adjusting block 156 is fixedly installed on the clamping assembly 100, and the second threaded adjusting block 156 is threadedly connected to the second threaded adjusting rod 154. A second rotating adjusting disk 157 is also provided on the second threaded adjusting rod 154, and the second rotating adjusting disk 157 is provided with a scale.

[0048] In this embodiment, conveyors 210 are respectively provided at both ends of the clamping channel 200. The conveyors 210 are single belt conveyors. The product is delivered to one end of the clamping channel 200 by the conveyors 210, and the product is clamped and transported to the other end of the clamping channel 200 by two clamping components 100. The product is suspended in the middle of the clamping channel 200, which facilitates the inspection or processing of the bottom of the product.

[0049] In this embodiment, the clamping assembly 100 is provided with a mounting plate 103, and the driving wheel 111, driven wheel 112, driving device 160 and tension idler wheel 121 are respectively fixedly connected to the mounting plate 103. Each transmission assembly is an independent moving part, making installation more convenient.

[0050] The crank 122 passes through the mounting plate 103. The locking device 130 includes a fixed shaft seat 131 sleeved on the crank 122. The fixed shaft seat 131 is fixedly mounted on the mounting plate 103. A locking nut 132 is provided above the fixed shaft seat 131 and is threadedly connected to the crank 122. By fixing the tension adjustment mechanism 120 to the mounting plate 103 through the locking device 130, the crank 122 will not rotate when the belt 113 moves, thus preventing the tension idler pulley 121 from shifting and the tension of the belt 113 from changing, thereby improving the stability of the equipment.

[0051] The top of the crank 122 is provided with a wrench connection port 126. By providing the wrench connection port 126, it can be adapted to a wrench, making it easier to rotate the crank 122. Specifically, the wrench connection port 126 can be a square head, hexagonal head, octagonal head, or other types of interface.

[0052] In this embodiment, the tensioning idler pulley 121 includes a central shaft 127, a bearing 128, and an idler pulley outer ring 129. The bearing 128 is rotatably connected to the central shaft 127, and the idler pulley outer ring 129 is rotatably connected to the bearing 128. By setting the idler pulley outer ring 129 and the central shaft 127, and placing the bearing 128 between the idler pulley outer ring 129 and the central shaft 127, the idler pulley outer ring 129 will rotate under the drive of the belt 113 when the belt 113 moves. This avoids the belt 113 from constantly slipping and rubbing on the tensioning idler pulley 121, thus improving the service life of the belt 113. At the same time, it reduces the resistance of friction to the movement of the belt 113, thereby improving the transmission efficiency of the belt 113.

[0053] In the embodiments of this application, please refer to Figure 5 The driving pulley 111 includes a transmission rod 114, a flange bearing 115, and a driving shaft synchronous pulley 116. The transmission rod 114 is connected to the drive unit 160, the flange bearing 115 is connected to the transmission rod 114, and the driving shaft synchronous pulley 116 is connected to the flange bearing 115. The driven pulley 112 includes a driven shaft synchronous pulley 117, which is connected to the driving shaft synchronous pulley 116 via a belt 113. The synchronous pulleys are mounted using flange bearings, resulting in a more secure installation.

[0054] This application provides a testing device, which includes the clamping and transmission device described in the above embodiment.

[0055] The testing equipment in this embodiment uses the clamping transmission device described in the above embodiment. The clamping transmission device, by setting two clamping components 100, can clamp the product in the clamping channel 200 between the two clamping components 100, and drive the product to move via a pulley set 110. With this structure, the product does not need to be placed on the conveyor line; its bottom is suspended, facilitating inspection, processing, cleaning, and other operations on the bottom of the product. By setting a tension adjustment mechanism 120 on the clamping component 100, the tension of the belt 113 can be adjusted. When the belt 113 is too loose, it can be tightened to prevent slippage or unstable product clamping during transmission. When the belt 113 is too tight, it can be loosened to prevent excessive tension and breakage, thus extending the belt 113's lifespan. The tension adjustment mechanism of this application embodiment compresses the belt 113 by means of a tension idler wheel 121 disposed on one side of the belt 113. The belt 113 is deformed by the compression and then tensioned. The degree of compression deformation of the belt 113 varies depending on the position of the tension idler wheel 121 on one side of the belt 113. Therefore, the tension of the belt 113 can be adjusted by adjusting the position of the tension idler wheel 121. A crank rod 122 is fixedly connected to the tension idler wheel 121, so that when the crank rod 122 rotates, the tension idler wheel 121 rotates with the crank rod 122. Because the crank rod 122... The central axis is parallel to the central axis of the tension idler wheel 121. Therefore, when the crank rod 122 rotates, the central axis of the tension idler wheel 121 will rotate around the central axis of the crank rod 122. That is, the tension idler wheel 121 will rotate as a whole around the central axis of the crank rod 122, thus changing the position of the tension idler wheel 121 and the degree of compression on the belt 113. Therefore, the tension of the belt 113 can be adjusted by rotating the crank rod 122 without adjusting the position of the driving wheel 111 or the driven wheel 112, which will not affect the clamping effect. The operation is simple, convenient and quick. To prevent the belt 113 from changing its tension by rotating the crank rod 122 when the belt 113 moves, a locking device 130 is connected to the crank rod 122. The crank rod 122 can only be rotated after the locking device 130 is released, which improves the stability of the equipment.

[0056] In some alternative embodiments, the functions / operations mentioned in the block diagrams may not occur in the order shown in the operation diagrams. For example, depending on the functions / operations involved, two consecutively shown blocks may actually be executed substantially simultaneously, or the blocks may sometimes be executed in reverse order.
